The impact of traditional psychiatric services and case management services on the functioning of people with schizophrenia: A cross-national study in Nova Scotia and Texas

The purpose of this study was to determine the impact of traditional psychiatric services with case management services on the functioning of people with schizophrenia. Traditional services were defined as routine clinic services consisting of medication follow-along, psychotherapy, and support services. Case management consisted of activities involved in linking, planning, and monitoring services for the outpatient client who has schizophrenia. The target population was adult schizophrenics who had been receiving outpatient clinic services for a minimum of six months. Structured interviews were conducted using standardized scales (e.g., Quality of Life, Self-Efficacy, and Brief Symptom Inventory) with 78 outpatient client volunteers from two sites: Nova Scotia (Canada) and Texas (USA). The researcher tested for differences in psychiatric symptomatology, recidivism, and quality of life for persons with schizophrenia receiving traditional psychiatric services in Nova Scotia and traditional plus case management services in Texas. Data were collected from the structured interviews and medical records review forms. Types of services were blocked into low and high levels of Intensity (frequency x minutes) and compared to determine the relative contribution of each. Finally, the role of clients' self-efficacy was tested as an intervening variable. Although the findings did not support the hypotheses in the direction anticipated, there were some interesting and useful results. From the Nova Scotia site, clients who received low levels of services were hospitalized less compared to the Texas site. The more psychotic a patient was the higher their involvement in medication follow-along and the more monitoring they received. The more psychotherapy received, the lower the reported satisfaction with social relationships. Of particular interest is the role that self-efficacy played in improved client outcomes. Although self-efficacy scores were related to improved functioning, the mechanism for this still needs to be clarified through subsequent research. ^

A cross-sectional analysis of the association between polycyclic aromatic hydrocarbons and diesel particulate matter exposures and hypertension among individuals of Mexican origin residing in Houston, TX

Background. Research has shown that elevations of only 10 mmHg diastolic blood pressure (BP) and 5 mmHg systolic BP are associated with substantial (as large as 50%) increases in risks for cardiovascular disease, a leading cause of death, worldwide. Epidemiological studies have found that particulate matter (PM) increases blood pressure (BP) and many biological mechanisms which may suggest that the organic matter of PM contributes to the increase in BP. To understand components of PM which may contribute to the increase in BP, this study focuses on diesel particulate matter (DPM) and polycyclic aromatic hydrocarbons (PAHs). To our knowledge, there have been only four epidemiological studies on BP and DPM, and no epidemiological studies on BP and PAHs. ^ Objective. Our objective was to evaluate the association between prevalent hypertension and two ambient exposures: DPM and PAHs amongst the Mano a Mano cohort. ^ Methods. The Mano a Mano cohort which was established by the M.D. Anderson Cancer Center in 2001, is comprised of individuals of Mexican origin residing in Houston, TX. Using geographical information systems, we linked modeled annual estimates of PAHs and DPM at the census track level from the U.S. Environmental Protection Agency's National-Scale Air Toxics Assessment to residential addresses of cohort members. Mixed-effects logistic regression models were applied to determine associations between DPM and PAHs and hypertension while adjusting for confounders. ^ Results. Ambient levels of DPM, categorized into quartiles, were not statistically associated with hypertension and did not indicate a dose response relationship. Ambient levels of PAHs, categorized into quartiles, were not associated with hypertension, but did indicate a dose response relationship in multiple models (for example: Q2: OR = 0.98; 95% CI, 0.73–1.31, Q3: OR = 1.08; 95% CI, 0.82–1.41, Q4: OR = 1.26; 95% CI, 0.94–1.70). ^ Conclusion. This is the first assessment to analyze the relationship between ambient levels of PAHs and hypertension and it is amongst a few studies investigating the association between ambient levels of DPM and hypertension. Future analyses are warranted to explore the effects DPM and PAHs using different categorizations in order to clarify their relationships with hypertension.^

The Relationship of Provincial Economic Level and Child Injury Mortality in Thailand: A Cross-Sectional Analysis in a Middle Income Country

The objective of this cross-sectional study was to examine the relationship of provincial economic development indices with incidences of child injury mortality in Thailand from 1999 - 2001. All injury deaths among children age 1-14 years were included. The independent variables included gross provincial product per capita (GPP/c), poverty and inequality indices, material and social deprivation indices, population in rural/ urban areas, and migration. Due to multicollinearity of such variables, the 76 provinces were categorized by GPP/c quartile, and means of overall injury, drowning, and transport-related mortality rates were compared among quartile groups. Spearman’s rho correlation between GPP/c and injury mortality rates was also performed. Finally, factor analysis was employed to create a set of factors to be treated as uncorrelated variables and stepwise multiple regression was carried out for the effects of the factors on injury mortality rates. A significant direct relationship was observed between GPP/c and overall injury mortality among children age 1-4 years, and 10-14 year-olds of both genders. Drowning was the main cause of this relationship among children age 1-4 years, and transport-related injury was the principle cause among children age 10-14 years. Conversely, provinces with lower GPP/c experienced higher injury mortality rates among school-age children 5-9 years old for both genders, mostly due to drowning. Factor analysis, and multiple regression results confirmed the relationships between economic development and injury mortality rates. These findings revealed that economic development had an adverse impact on injury-related mortality among children 1 to 4 and 10 to14 in Thailand.

The development of professor's professional knowledge in Psychology

This work belongs to the Project "Teaching and learning Psychology: a study of the educational practice in professors and beginners". It is part of an investigation program developed in the context of the subject "Didactic and Practical Planning of Psychology teaching" in which we have been working since 1998. This subject is also considered as the final stage of the formative itinerary for Psychology s professors. The reached results show the incidence that the beliefs and professors' representations have in the teaching processes. By getting into the studies centered in the educational knowledge we guide the inquiry around the development of the professor's professional knowledge and particularly the development of their formation. Our proposal contemplates a formation device which incorporates the observation, reflection, evaluation and self-evaluation of the practice in order to facilitate the reconstruction, significance and re-significance of the teaching and learning processes by giving relevance to the development of the teacher professional knowledge. The analysis of teaching practices process reveals that the mediations that cross the knowledge in the being taught instances are constituted in reflections axes. This involves the future professor's relationship with the knowledge and their projection in the construction of the professional identity.

The causal relationships in mean and variance between stock returns and foreign institutional investment in India

This paper examines the causalities in mean and variance between stock returns and Foreign Institutional Investment (FII) in India. The analysis in this paper applies the Cross Correlation Function approach from Cheung and Ng (1996), and uses daily data for the timeframe of January 1999 to March 2008 divided into two periods before and after May 2003. Empirical results showed that there are uni-directional causalities in mean and variance from stock returns to FII flows irrelevant of the sample periods, while the reverse causalities in mean and variance are only found in the period beginning with 2003. These results point to FII flows having exerted an impact on the movement of Indian stock prices during the more recent period.

Análisis de sistemas dinámicos y complejos en la Liga Profesional de Balonmano de España = Complex and dynamical systems analysis in Spanish Professional Handball League

El propósito de esta tesis fue estudiar el rendimiento ofensivo de los equipos de balonmano de élite cuando se considera el balonmano como un sistema dinámico complejo no lineal. La perspectiva de análisis dinámica dependiente del tiempo fue adoptada para evaluar el rendimiento de los equipos durante el partido. La muestra general comprendió los 240 partidos jugados en la temporada 2011-2012 de la liga profesional masculina de balonmano de España (Liga ASOBAL). En el análisis posterior solo se consideraron los partidos ajustados (diferencia final de goles ≤ 5; n = 142). El estado del marcador, la localización del partido, el nivel de los oponentes y el periodo de juego fueron incorporados al análisis como variables situacionales. Tres estudios compusieron el núcleo de la tesis. En el primer estudio, analizamos la coordinación entre las series temporales que representan el proceso goleador a lo largo del partido de cada uno de los dos equipos que se enfrentan. Autocorrelaciones, correlaciones cruzadas, doble media móvil y transformada de Hilbert fueron usadas para el análisis. El proceso goleador de los equipos presentó una alta consistencia a lo largo de todos los partidos, así como fuertes modos de coordinación en fase en todos los contextos de juego. Las únicas diferencias se encontraron en relación al periodo de juego. La coordinación en los procesos goleadores de los equipos fue significativamente menor en el 1er y 2º periodo (0–10 min y 10–20 min), mostrando una clara coordinación creciente a medida que el partido avanzaba. Esto sugiere que son los 20 primeros minutos aquellos que rompen los partidos. En el segundo estudio, analizamos los efectos temporales (efecto inmediato, a corto y a medio plazo) de los tiempos muertos en el rendimiento goleador de los equipos. Modelos de regresión lineal múltiple fueron empleados para el análisis. Los resultados mostraron incrementos de 0.59, 1.40 y 1.85 goles para los periodos que comprenden la primera, tercera y quinta posesión de los equipos que pidieron el tiempo muerto. Inversamente, se encontraron efectos significativamente negativos para los equipos rivales, con decrementos de 0.50, 1.43 y 2.05 goles en los mismos periodos respectivamente. La influencia de las variables situacionales solo se registró en ciertos periodos de juego. Finalmente, en el tercer estudio, analizamos los efectos temporales de las exclusiones de los jugadores sobre el rendimiento goleador de los equipos, tanto para los equipos que sufren la exclusión (inferioridad numérica) como para los rivales (superioridad numérica). Se emplearon modelos de regresión lineal múltiple para el análisis. Los resultados mostraron efectos negativos significativos en el número de goles marcados por los equipos con un jugador menos, con decrementos de 0.25, 0.40, 0.61, 0.62 y 0.57 goles para los periodos que comprenden el primer, segundo, tercer, cuarto y quinto minutos previos y posteriores a la exclusión. Para los rivales, los resultados mostraron efectos positivos significativos, con incrementos de la misma magnitud en los mismos periodos. Esta tendencia no se vio afectada por el estado del marcador, localización del partido, nivel de los oponentes o periodo de juego. Los incrementos goleadores fueron menores de lo que se podría esperar de una superioridad numérica de 2 minutos. Diferentes teorías psicológicas como la paralización ante situaciones de presión donde se espera un gran rendimiento pueden ayudar a explicar este hecho. Los últimos capítulos de la tesis enumeran las conclusiones principales y presentan diferentes aplicaciones prácticas que surgen de los tres estudios. Por último, se presentan las limitaciones y futuras líneas de investigación. ABSTRACT The purpose of this thesis was to investigate the offensive performance of elite handball teams when considering handball as a complex non-linear dynamical system. The time-dependent dynamic approach was adopted to assess teams’ performance during the game. The overall sample comprised the 240 games played in the season 2011-2012 of men’s Spanish Professional Handball League (ASOBAL League). In the subsequent analyses, only close games (final goal-difference ≤ 5; n = 142) were considered. Match status, game location, quality of opposition, and game period situational variables were incorporated into the analysis. Three studies composed the core of the thesis. In the first study, we analyzed the game-scoring coordination between the time series representing the scoring processes of the two opposing teams throughout the game. Autocorrelation, cross-correlation, double moving average, and Hilbert transform were used for analysis. The scoring processes of the teams presented a high consistency across all the games as well as strong in-phase modes of coordination in all the game contexts. The only differences were found when controlling for the game period. The coordination in the scoring processes of the teams was significantly lower for the 1st and 2nd period (0–10 min and 10–20 min), showing a clear increasing coordination behavior as the game progressed. This suggests that the first 20 minutes are those that break the game-scoring. In the second study, we analyzed the temporal effects (immediate effect, short-term effect, and medium-term effect) of team timeouts on teams’ scoring performance. Multiple linear regression models were used for the analysis. The results showed increments of 0.59, 1.40 and 1.85 goals for the periods within the first, third and fifth timeout ball possessions for the teams that requested the timeout. Conversely, significant negative effects on goals scored were found for the opponent teams, with decrements of 0.59, 1.43 and 2.04 goals for the same periods, respectively. The influence of situational variables on the scoring performance was only registered in certain game periods. Finally, in the third study, we analyzed the players’ exclusions temporal effects on teams’ scoring performance, for the teams that suffer the exclusion (numerical inferiority) and for the opponents (numerical superiority). Multiple linear regression models were used for the analysis. The results showed significant negative effects on the number of goals scored for the teams with one less player, with decrements of 0.25, 0.40, 0.61, 0.62, and 0.57 goals for the periods within the previous and post one, two, three, four and five minutes of play. For the opponent teams, the results showed positive effects, with increments of the same magnitude in the same game periods. This trend was not affected by match status, game location, quality of opposition, or game period. The scoring increments were smaller than might be expected from a 2-minute numerical playing superiority. Psychological theories such as choking under pressure situations where good performance is expected could contribute to explain this finding. The final chapters of the thesis enumerate the main conclusions and underline the main practical applications that arise from the three studies. Lastly, limitations and future research directions are described.

Business, development and inclusive supply chains. Exploring pathways for the sustainable incorporation of the poor as suppliers in agrifood supply chains

El panorama global está cambiando, y esto influye sobre la forma en la que entendemos y tratamos de alcanzar un desarrollo humano sostenible. El crecimiento de la población conlleva una mayor presión sobre los recursos, pero también supone una mayor cantidad de mano de obra y de talento; la concentración en áreas urbanas está cambiando las dinámicas sociales y desafiando los canales de comercialización tradicionales, pero también genera nuevos mercados y fomenta la innovación; los cambios en la economía global están reduciendo los tradicionales desequilibrios de poder entre los países occidentales y el resto del mundo; y las crecientes interconexiones crean nuevos riesgos pero también oportunidades para lanzar iniciativas de alcance global. Todas estas tendencias nos están obligando a repensar qué es el desarrollo humano y de qué manera deberíamos afrontar el reto de la pobreza. Es comúnmente aceptado que la globalización implica interdependencia y que, para conseguir un desarrollo humano sostenible, la colaboración entre actores de distintos ámbitos es necesaria. Se observa una creciente convergencia de temas, intereses y soluciones en torno al desarrollo sostenible, incluso en diferentes países y sectores, lo que está facilitando la colaboración estratégica entre empresas, gobiernos y sociedad civil. Existen pocas duda a día de hoy sobre el papel fundamental que las empresas deben desempeñar en la transición mundial hacia la sostenibilidad ambiental y la erradicación de la pobreza. Las empresas están evolucionando desde un enfoque tradicional centrado en la maximización de beneficios económicos hacia un enfoque holístico que integra la sostenibilidad y la responsabilidad social como parte del núcleo de negocio de las compañías. En el ámbito medioambiental, muchas empresas ya han comenzado a actuar y tratan de reducir sus emisiones, sus desechos y su consumo de energía. Sin embargo la contribución de las empresas a la reducción de la pobreza no está tan clara. Actualmente en torno a 1,2 miles de millones de personas viven en situación de extrema pobreza. La mayoría de estas personas aún vive en zonas rurales donde la mayor parte de la población activa trabaja en el sector agrícola. Por lo tanto, mejorar las oportunidades y reducir los riesgos de los productores más vulnerables en el sector de la agricultura puede ser un motor de desarrollo rural y reducción de la pobreza, especialmente en países de bajo nivel de desarrollo cuyas economías están fundamentalmente basadas en la agricultura. Algunas empresas comienzan a incluir a los pobres en sus operaciones como consumidores, proveedores y emprendedores. Esta tesis se centra en las potenciales oportunidades relacionadas con la incorporación sostenible de los pobres como proveedores de productos y/o de mano de obra. La colaboración entre empresas y productores vulnerables de países en desarrollo es un tema relativamente nuevo y todavía poco estudiado. La pregunta que guía esta tesis es: “¿Cómo pueden las empresas facilitar la inclusión sostenible en cadenas de suministro de productores vulnerables de los países menos desarrollados?”. Para responder a la pregunta anterior, la autora ha aplicado una metodología de casos de estudio. Esta metodología se considera apropiada porque la investigación sobre cadenas de suministro inclusivas es todavía escasa y porque es necesario entender en profundidad un fenómeno de la vida real, y para ello es fundamental conocer su contexto. En primer lugar, se realiza una revisión de literatura para identificar las proposiciones y los constructos teóricos que guiarán la posterior recogida de datos. La revisión de literatura se divide en dos partes: una más general que explora la dimensión social de la sostenibilidad en cadenas de suministro, y una más específica que se centra en la incorporación de los pobres como proveedores en cadenas de suministro. A lo largo de la última década, ha habido un crecimiento exponencial de los estudios académicos sobre la sostenibilidad de las cadenas de suministro, pero la mayoría de los esfuerzos se han dirigido hacia la dimensión medioambiental de la sostenibilidad. Por lo tanto la revisión de literatura, que se presenta en la Sección 3.1 (página 35) y que profundiza en la sostenibilidad social de las cadenas de suministro, puede considerarse una contribución en sí misma. Esta revisión de literatura revela que la investigación sobre aspectos sociales en cadenas de suministro está cobrando impulso en distintas áreas de conocimiento, principalmente en los ámbitos de investigación sobre “gestión de cadenas de suministro”, “responsabilidad social corporativa” y “estudios del desarrollo”. La investigación existente sobre sostenibilidad social de cadenas de suministro se centra en tres temas: aclarar la definición de sostenibilidad social; analizar la implementación de estrategias de sostenibilidad social en cadenas de suministro; y estudiar el apoyo de las em presas líderes a proveedores vulnerables para facilitar su transición hacia la sostenibilidad. Un marco conceptual que resume los principales hallazgos de esta primera parte de la revisión de literatura es planteado en la Figura 7 (página 48). No obstante, en el área de investigación que está emergiendo en torno a la sostenibilidad social de las cadenas de suministro, los estudios relacionados con la reducción de la pobreza son aún escasos. Además se aprecia una falta de contribuciones desde y sobre los países menos desarrollados, así como una clara tendencia a reflejar la visión de las empresas líderes de las cadenas de suministro, olvidando la perspectiva de los proveedores. La segunda parte de la revisión de literatura presentada en la Sección 3.2 (página 51) profundiza en tres líneas de investigación que exploran, desde distintas perspectivas, la inclusión de los pobres en cadenas de suministro. Estas líneas son “Global Value Chains” (GVC), “Base of the Pyramid” (BoP) y “Sustainable Supply Chain Management” (SSCM). La investigación en GVC analiza las cadenas de suministro desde la perspectiva de la globalización económica y el comercio internacional, poniendo especial énfasis en las implicaciones para los países en desarrollo y las comunidades vulnerables. GVC caracteriza las cadenas de suministro según la forma en la que son gobernadas, las oportunidades de mejora que existen para los productores que forman parte de la cadena y el grado de inclusión o exclusión de las comunidades más pobres y vulnerables. La investigación en BoP explora las relaciones comerciales entre empresas y comunidades pobres. La premisa fundamental del concepto BoP es la posibilidad de combinar la generación de beneficios con la reducción de la pobreza. La propuesta original es que mediante la venta de productos y servicios a las comunidades pobres de países en desarrollo, la pobreza puede ser reducida al tiempo que las empresas incrementan sus beneficios, especialmente las grandes empresas multinacionales. Esta idea ha ido evolucionando y, a día de hoy, los investigadores BoP consideran la incorporación de los pobres no sólo como consumidores sino también como empleados, proveedores y co-creadores. La investigación en SSCM ha estado fundamentalmente orientada al estudio de la dimensión medioambiental de la sostenibilidad de cadenas de suministro. Sin embargo, la creciente externalización de la producción a países en desarrollo y las demandas de los grupos de interés para que las empresas aborden todos los aspectos de la sostenibilidad han llevado a los académicos de SSCM a reconocer la importancia de integrar asuntos relacionados con la reducción de la pobreza en sus investigaciones. Algunos estudios comienzan a apuntar los principales retos a los que se enfrentan las empresas para colaborar con productores vulnerables en sus cadenas de suministro. Estos retos son: falta de comunicación, altos costes de transacción y el incremento de la complejidad de las operaciones. Las contribuciones de estas tres líneas de investigación son complementarias para el estudio de las cadenas de suministro inclusivas. Sin embargo, raramente han sido consideradas conjuntamente, ya que pertenecen a ámbitos de conocimiento distintos. Esta tesis integra las aportaciones de GVC, BoP y SSCM en un marco conceptual para la creación y gestión de cadenas de suministro inclusivas. Este marco conceptual para cadenas de suministro inclusivas queda representado en la Figura 9 (página 68). El marco conceptual refleja las motivaciones que llevan a las empresas a colaborar con productores vulnerables, los retos a los que se enfrentan al hacerlo, y los caminos o estrategias que están siguiendo para construir y operar cadenas de suministro inclusivas de manera que sean beneficiosas tanto para la empresa como para los productores vulnerables. A fin de validar y refinar el marco conceptual propuesto, tres casos de estudio se llevan a cabo. Las cadenas de suministro analizadas por los casos de estudio pertenecen al sector agrícola y sus principales proveedores se encuentran en países de África subsahariana. Múltiples métodos de recolección de datos y triangulación son utilizados para mejorar la fiabilidad de los datos. La autora desarrolló trabajos de campo en Senegal, Etiopía y Tanzania. Estos viajes permitieron enriquecer el proceso de recogida de información mediante entrevistas semiestructuradas y conversaciones informales con los principales actores de la cadena de suministro y mediante la observación directa de los procesos y las interacciones entre productores vulnerables y empresas. El Caso de estudio A (Sección 5.1 en página 96) es un caso de estudio único. Analiza la cadena de suministro local de verduras en Senegal. La organización focal es Manobi, una empresa senegalesa que provee servicios de bajo coste a emprendedores locales del sector agrícola. El Caso de estudio A proporciona un interesante análisis del funcionamiento de una cadena de suministro local en un país en desarrollo y muestra como la provisión de servicios profesionales puede mejorar el desempeño de productores vulnerables. El Caso de estudio B (Sección 5.2 en página 122) es un caso de estudio único. Analiza la cadena de suministro global de flor cortada con origen en Etiopía. La organización focal es EHPEA, la Asociación Etíope de Productores y Exportadores Hortícolas, cuya misión es promover y salvaguardar la posición competitiva del sector agrícola etíope en el mercado global. El Caso de estudio B ayuda a comprender mejor la perspectiva de los proveedores respecto a los requerimiento de sostenibilidad del mercado global. También muestra cómo la inclusión de los productores en el proceso de desarrollo de un estándar privado facilita su implementación posterior. El Caso de estudio C (Sección 5.3 en página 143) es un caso de estudio múltiple. Analiza la cadena de suministro global de café especial con origen en Tanzania. Las organizaciones focales son comerciantes que conectan de manera directa a pequeños agricultores de café en países en desarrollo con empresas tostadoras de café en países desarrollados. El Caso de estudio C muestra cómo un pequeño agricultor puede proveer un producto “premium” al mercado global, y participar en un segmento diferenciado del mercado a través de una cadena de suministro transparente y eficiente. Las aportaciones empíricas de los casos de estudio ayudan a validar y mejorar el marco conceptual sobre cadenas de suministro inclusivas (ver discusión en el Capítulo 6 en página 170). El resultado es la propuesta de una nueva versión del marco conceptual representado en la Figura 40 (página 195). Los casos de estudio también proporcionan interesantes aportaciones en relación a la gestión de cadenas de suministro inclusivas y muestran las perspectivas de distintos actores implicados. Esta tesis arroja luz sobre el papel de las empresas en la creación y la gestión de cadenas de suministro inclusivas llevando a cabo una revisión de literatura multidisciplinar y analizando tres casos de estudio en países africanos. Como resultado, esta tesis presenta una serie de contribuciones empíricas y teóricas al ámbito de investigación emergente en torno a las cadenas de suministro inclusivas (Capítulo 7). Esta tesis también pretende ser útil a profesionales que deseen facilitar la incorporación de los pobres como proveedores en condiciones justas y beneficiosas. ABSTRACT The global outlook is changing, and this is influencing the way we understand and try to achieve sustainable human development. Population growth entails increasing pressure over resources, but it also provides greater workforce and talent; concentration in urban areas is changing social dynamics and challenging traditional marketing channels, but also creating news markets and driving innovation; the global economy shift is rebalancing the traditional power imbalance between Western countries and the rest of the world, making new opportunities to arise; and interconnections and global interdependence create new risks but also opportunities for launching initiatives with a global reach. All these trends are impelling us to rethink what development is and in which way poverty alleviation should be approached. It is generally agreed that globalization implies interdependence and, in order to achieve sustainable human development, collaboration of all actors is needed. A convergence of issues, interests and solutions related to sustainable development is being observed across countries and sectors, encouraging strategic collaboration among companies, governments and civil society. There is little doubt nowadays about the crucial role of the private sector in the world’s path towards environmental sustainability and poverty alleviation. Businesses are evolving from a “business as usual” stance to a more sustainable and responsible approach. In the environmental arena, many companies have already “walk the talk”, implementing environmental management systems and trying to reduce emissions and energy consumption. However, regarding poverty alleviation, their contribution is less clear. There are around 1.2 billion people living in extreme poverty. Most of this people still live in rural areas where the agricultural sector employs a big part of the active population. Therefore, improving opportunities and reducing risks for vulnerable producers in the agri-food sector can be a primary engine of rural development and poverty alleviation, particularly in the poor, agriculture-based economies of least developed countries. Some companies are beginning to include the poor into their operations as consumers, suppliers and entrepreneurs. This thesis focuses specifically on the potential opportunities related to the sustainable incorporation of the poor as suppliers of products and/or labor. Business collaboration with vulnerable producers in developing countries is a relatively new trend and it is still understudied. The overall question guiding this thesis is: “How can businesses facilitate the sustainable inclusion of vulnerable producers from least developed countries into supply chains?”. In order to answer the research question, the author has applied a case study research strategy. This methodology is considered appropriate because research about inclusive supply chains is still at an early stage, and because there is a need to understand a real-life phenomenon in depth, but such understanding encompasses important contextual conditions. First, a literature review is conducted, in order to identify the research propositions and theoretical constructs that will guide the data collection. The literature review is divided in two parts: a more general one that explores the social dimension of sustainability of supply chains, and a more specific one that focuses on the incorporation of the poor as suppliers in supply chains. During the last decade, there has been an exponential growth of studies in the field of supply chain sustainability, but research efforts have traditionally been directed towards the analysis of the environmental dimension. Therefore, the literature review presented in Section 3.1 (page 35) that delves into social sustainability of supply chains can be considered a contribution in itself. This literature review reveals that the investigation of social issues in supply chains is gaining momentum and comes from different academic disciplines, namely Supply Chain Management, Corporate Social Responsibility and Development Studies. Existing research about social sustainability of supply chains focuses on three issues: clarify the definition of social sustainability; analyze the implementation of social sustainability strategies in supply chains; and study lead companies’ support to vulnerable suppliers in their transition towards sustainability. A conceptual framework that outlines the main findings that emerge from this first part of literature review is proposed in Figure 7 (page 48). Nevertheless, in this nascent field of social sustainability of supply chains, studies related to poverty alleviation are still scarce. Moreover, a lack of contributions from and about least developed countries has been observed, as well as a tendency to reflect on the lead firms’ standpoint, neglecting the suppliers’ perspective. The second part of the literature review (Section 3.2 in page 51) delves into three research streams that are exploring the inclusion of the poor into supply chains from different viewpoints. These research streams are Global Value Chains (GVC), Base of the Pyramid (BoP) and Sustainable Supply Chain Management (SSCM). GVC research discusses the dynamics of economic globalization and international trade, putting special emphasis in the implications for developing countries and vulnerable communities. GVC characterizes supply chains by the way they are governed, the upgrading opportunities that exist for producers in the chain and the degree of inclusion or exclusion of impoverished communities. BoP research explores trading relationships between businesses and impoverished communities. The core premise of the BoP concept is the possibility to combine profits with poverty alleviation. The original BoP proposition is that by marketing innovative products and services to poor communities in developing countries, poverty would be reduced and companies would increase their benefits, especially multinational companies. This idea has evolved to consider the incorporation of the poor to business activities not only as consumers, but also as employees, entrepreneurs and co-creators. The SSCM school of thought has mainly focused on studying the environmental dimension of supply chain sustainability, neglecting the consideration of the social perspective. However, in recent years, increasing outsourcing of production to developing countries and stakeholders’ demands for a more holistic approach to business sustainability have led SSCM scholars to acknowledge the importance of integrating poverty concerns in this field’s research agenda. Some SSCM studies identify the main operational challenges for companies which engage with vulnerable suppliers in their supply chains: missing communication, higher transactional and operational costs and increased complexity. Contributions from these three research streams are complementary for the study of inclusive supply chains. However, they have been rarely considered together, since they belong to different research areas. This thesis seeks to play a dovetailing role in this scenario by proposing a conceptual framework for creating and operating inclusive supply chains that builds on contributions from GVC, SSCM and BoP research. This framework for inclusive supply chains is depicted in Figure 9 (page 68), and explains the motivations that drive businesses to collaborate with vulnerable suppliers, the chal lenges they face in doing so, and the pathways they are following in order to build and operate inclusive supply chains profitably for both buying companies and vulnerable suppliers. In order to validate and refine the proposed framework, three case studies are carried out. The supply chains analyzed by the case studies belong to the agri-food sector and source from Sub-Saharan African countries. Multiple data collection methods and triangulation are used in order to improve reliability of findings. The author carried out field work in Senegal, Ethiopia and Tanzania. These travels enriched the data collection process, providing semi-structured interviews and informal conversations with the main actors in the supply chains, as well as direct observation of processes and interactions among companies and vulnerable suppliers. Case study A (Section 5.1 in page 96) is a single case study. It analyzes a local supply chain in Senegal providing vegetables to the local market. The focal organization is Manobi, a Senegalese inclusive business which provides affordable ICT services to local entrepreneurs in the agri-food sector. Case study A provides interesting insights into the dynamics of local supply chains and how professional services can help to improve their performance. Case study B (Section 5.2 in page 122) is a single case study. It analyzes a global supply chain with origin in Ethiopia providing cut flowers to the global commodity market. The focal organization is EHPEA, Ethiopian Horticulture Producers and Exporters Association, whose mission is to promote and safeguard the competitive position of the Ethiopian horticulture sector within the global market. Case study B helps to better understand the suppliers’ perspective regarding global market sustainability requirements and shows how the inclusion of suppliers in the process of development of a private standard has a positive impact in its implementation. Case study C (Section 5.3 in page 143) is a multiple case study. It analyzes a global supply chain with origin in Tanzania providing coffee to the global niche market of specialty coffee. The focal organizations are traders who are directly connecting smallholder coffee farmers in developing countries to coffee roasters in developed countries. Case study C shows how smallholder farmers can supply a premium product and be incorporated in a differentiated market segment through a transparent and efficient supply chain. The empirical findings from the case studies help to validate and refine the conceptual framework (see discussion in Chapter 6). The proposal of a new version of the conceptual framework is depicted in Figure 40 (page 195). The case studies also provide interesting insights related to the management of inclusive supply chains and show the perspectives of the different actors involved. This thesis sheds some light on the role of businesses in the creation and operation of inclusive supply chains by carrying out a cross-disciplinary literature review and analyzing three case studies in African countries. In doing so, this thesis presents a series of theoretical and empirical contributions to the emerging academic field of inclusive supply chains (Chapter 7). This thesis also intends to be useful to practitioners willing to improve the incorporation of the poor as suppliers in fair and profitable conditions.

Análisis sectorial y posicionamiento estratégico: el caso de la industria naval hacia el 2050

El motivo de abordar esta Tesis responde al hecho personal de haber vivido históricamente momentos cumbre de la Construcción Naval en España y no dejar de plantearme, a pesar de mi distancia del sector desde el punto de vista profesional, en las opciones de futuro para volver a ser competitivos en un sector que ha tenido un peso tan importante en la economía española, y que tanto ha ilusionado a centenares de profesionales y compañeros a lo largo de muchas décadas con el optimismo de estar aportando valor para que España fuera competitiva. A lo largo de los últimos años, y la relación con el ámbito de la dirección de Empresas desde el punto de vista de una Escuela de Negocios, así como el contacto con enfoques estratégicos en sectores muy diversos me animó a plantearme la Tesis con el objetivo de reflejar el estado actual del sector y poder valorar alternativas de futuro para la Construcción Naval española, aun sabiendo que son muchos los “maestros” realmente autorizados en nuestros país, con amplios conocimientos y experiencia, que muchas veces, a pesar de las propuestas y de los esfuerzos que han realizado para impulsar el sector, se han encontrado con situaciones adversas, bien de tipo económico, social‐laboral, político ‐a nivel nacional, europeo o global‐, etc., que han impedido un fortalecimiento del sector como todos hubiéramos deseado. La presión histórica ejercida por los países competidores en Construcción naval del ámbito asiático y lejano oriente, así como los compromisos derivados de las Directivas europeas, han obligado al sector de la Construcción Naval en España a buscar unos nuevos posicionamientos estratégicos presentes y, sobre todo, de futuro. Partiendo de un análisis del sector naval, tanto del mercado nacional como del internacional, con especial foco en los países líderes, se plantea investigar, siguiendo el modelo de Porter, las fuerzas competitivas que han influido en estas últimas décadas y que han conducido a la situación actual, valorando la estructura competitiva, el entorno relevante y los efectos de la globalización, con las amenazas de los nuevos y actuales competidores y las barreras existentes. Para abordar esta investigación se ha realizado un análisis del sector naval con la siguiente metodología: 1. Análisis del estado actual de la construcción naval en España. 2. Análisis del estado actual de la construcción naval en el mundo. 3. Estudio de la demanda en el mercado y evolución de la misma en los últimos años: muy centrada en los países líderes y más competitivos. 4. Estudio de las perspectivas de negocio en el sector marítimo y oceánico: estudio particular del transporte marítimo y una comparativa con la explotación de recursos oceánicos. Finalmente se decidió no abordar por falta de datos de futuro las construcciones militares. 5. Estudio de características de la industria naval española y capacidad de los astilleros. Se ha focalizado especialmente en la construcción para valorar la capacidad de futuro. 6. Análisis de fuerzas competitivas de la industria naval española a partir del modelo de Porter. En esta parte se incluyen alguno de los factores críticos externos e internos que ayudan a identificar barreras y estrategias en el entorno de la construcción naval como sector global. 7. Identificación de las oportunidades de negocio hacia el 2050. 8. Alternativas para una estrategia competitiva de actuación frente a las oportunidades de futuro en el 2050. Con esta Tesis se aporta un estudio competitivo actualizado, de acuerdo con el modelo de Porter, con el fin de proponer una posible estrategia competitiva de futuro, que posicione competitivamente la industria naval y el sector marítimo en España en las próximas décadas. ABSTRACT The reason for addressing this thesis responds to my personal experience about having lived historical moments summit Shipbuilding in Spain. Despite my distance from this industry from a professional point of view, I have never stopped wonder myself which are the options for the future to become competitive in an industry that has had such an important weight in the Spanish economy, which has excited so hundreds of professionals and peers through many decades with optimism to be adding value to Spain in order to be competitive again. Over recent years, and the relationship with the field of business management from the point of view of a business school, as well as contact with strategic approaches in diverse sectors encouraged me to wonder Thesis order to reflect the current state of the sector and to evaluate future alternatives for the Spanish Shipbuilding, knowing that many "teachers" really allowed in our country, with extensive knowledge and experience that often, despite proposals and the efforts that have been made to boost the sector, have met with adverse situations, whether economic, social and labor, political kind ‐at national, European or global‐level, etc., that have prevented a strengthening of all sectors we wished. The historical pressure from competing countries in Shipbuilding Asian area and Far East, as well as commitments arising from EU directives, have forced the shipbuilding industry in Spain to seek a new strategic positions present and, above all, future. Starting from an analysis of the shipbuilding sector, both national and international market, with special focus on the leading countries, we propose to investigate, following the model of Porter, the competitive forces that have influenced recent decades and have led to the current situation, assessing the competitive structure of the relevant environment and the effects of globalization, with the threat of new and existing competitors and barriers. To address this research has analyzed the naval sector with the following methodology: 1. Analysis of the current state of shipbuilding in Spain. 2. Analysis of the current state of shipbuilding in the world. 3. Study of the demand in the market and evolution of the same in recent years: very focused on the leading and most competitive countries. 4. Study of business prospects in the maritime and oceanic sector: private study of maritime transport and a comparison with the exploitation of ocean resources. Finally it was decided not to address a lack of data future military construction. 5. Study of characteristics of the Spanish shipbuilding and shipyard capacity. It is particularly focused on building the capacity to assess future. 6. Analysis of competitive forces of the Spanish shipbuilding industry from the model of Porter. In this part they include some critics of the external and internal factors that help identify barriers and strategies in the environment of global shipbuilding sector. 7. Identification of business opportunities by 2050. 8. Alternatives to a competitive strategy of action against future opportunities in 2050. This thesis has sought to provide a competitive study updated according to Porter's model, in order to propose a possible future competitive strategy to reach a competitive position at the shipbuilding industry and the maritime sector in Spain in the coming decades. The historical pressure from competing countries in the Asian sphere Shipbuilding and Far East, as well as commitments arising from EU directives have forced the shipbuilding industry in Spain to seek a new strategic positioning. Starting from an analysis of the shipbuilding sector, both national and international market, with a special focus on the leading countries, it is proposed to analyze, following the model of Porter, the competitive forces that have influenced in recent decades and have led to the current situation, studying the competitive structure of the relevant environment and the effects of globalization, with the threat of new and existing competitors and barriers. It concludes with a forecast of future market and business opportunities arising in the global environment of maritime and naval Industry, in order to propose a possible competitive strategy for the near future, which could help to achieve a competitive position on the shipbuilding and maritime sector in Spain for the coming decades.

Aprendizaje integrado en arquitectura con modelos virtuales : implementación de metodología BIM en la docencia universitaria

Los procesos de diseño y construcción en Arquitectura han mostrado un desarrollo de optimización históricamente muy deficiente cuando se compara con las restantes actividades típicamente industriales. La aspiración constante a una industrialización efectiva, tanto en aras de alcanzar mayores cotas de calidad así como de ahorro de recursos, recibe hoy una oportunidad inmejorable desde el ámbito informático: el Building Information Modelling o BIM. Lo que en un inicio puede parecer meramente un determinado tipo de programa informático, en realidad supone un concepto de “proceso” que subvierte muchas rutinas hoy habituales en el desarrollo de proyectos y construcciones arquitectónicas. La inclusión y desarrollo de datos ligados al proyecto, desde su inicio hasta el fin de su ciclo de vida, conlleva la oportunidad de crear una realidad virtual dinámica y actualizable, que por añadidura posibilita su ensayo y optimización en todos sus aspectos: antes y durante su ejecución, así como vida útil. A ello se suma la oportunidad de transmitir eficientemente los datos completos de proyecto, sin apenas pérdidas o reelaboración, a la cadena de fabricación, lo que facilita el paso a una industrialización verdaderamente significativa en edificación. Ante una llamada mundial a la optimización de recursos y el interés indudable de aumentar beneficios económicos por medio de la reducción del factor de incertidumbre de los procesos, BIM supone un opción de mejora indudable, y así ha sido reconocido a través de la inminente implantación obligatoria por parte de los gobiernos (p. ej. Gran Bretaña en 2016 y España en 2018). La modificación de procesos y roles profesionales que conlleva la incorporación de BIM resulta muy significativa y marcará el ejercicio profesional de los futuros graduados en las disciplinas de Arquitectura, Ingeniería y Construcción (AEC por sus siglas en inglés). La universidad debe responder ágilmente a estas nuevas necesidades incorporando esta metodología en la enseñanza reglada y aportando una visión sinérgica que permita extraer los beneficios formativos subyacentes en el propio marco BIM. En este sentido BIM, al aglutinar el conjunto de datos sobre un único modelo virtual, ofrece un potencial singularmente interesante. La realidad tridimensional del modelo, desarrollada y actualizada continuamente, ofrece al estudiante una gestión radicalmente distinta de la representación gráfica, en la que las vistas parciales de secciones y plantas, tan complejas de asimilar en los inicios de la formación universitaria, resultan en una mera petición a posteriori, para ser extraída según necesidad del modelo virtual. El diseño se realiza siempre sobre el propio modelo único, independientemente de la vista de trabajo elegida en cada momento, permaneciendo los datos y sus relaciones constructivas siempre actualizados y plenamente coherentes. Esta descripción condensada de características de BIM preconfiguran gran parte de las beneficios formativos que ofrecen los procesos BIM, en especial, en referencia al desarrollo del diseño integrado y la gestión de la información (incluyendo TIC). Destacan a su vez las facilidades en comprensión visual de elementos arquitectónicos, sistemas técnicos, sus relaciones intrínsecas así como procesos constructivos. A ello se une el desarrollo experimental que la plataforma BIM ofrece a través de sus software colaborativos: la simulación del comportamiento estructural, energético, económico, entre otros muchos, del modelo virtual en base a los datos inherentes del proyecto. En la presente tesis se describe un estudio de conjunto para explicitar tanto las cualidades como posibles reservas en el uso de procesos BIM, en el marco de una disciplina concreta: la docencia de la Arquitectura. Para ello se ha realizado una revisión bibliográfica general sobre BIM y específica sobre docencia en Arquitectura, así como analizado las experiencias de distintos grupos de interés en el marco concreto de la enseñanza de la en Arquitectura en la Universidad Europea de Madrid. El análisis de beneficios o reservas respecto al uso de BIM se ha enfocado a través de la encuesta a estudiantes y la entrevista a profesionales AEC relacionados o no con BIM. Las conclusiones del estudio permiten sintetizar una implantación de metodología BIM que para mayor claridad y facilidad de comunicación y manejo, se ha volcado en un Marco de Implantación eminentemente gráfico. En él se orienta sobre las acciones docentes para el desarrollo de competencias concretas, valiéndose de la flexibilidad conceptual de los Planes de Estudio en el contexto del Espacio Europeo de Educación Superior (Declaración de Bolonia) para incorporar con naturalidad la nueva herramienta docente al servicio de los objetivos formativo legalmente establecidos. El enfoque global del Marco de Implementación propuesto facilita la planificación de acciones formativas con perspectiva de conjunto: combinar los formatos puntuales o vehiculares BIM, establecer sinergias transversales y armonizar recursos, de modo que la metodología pueda beneficiar tanto la asimilación de conocimientos y habilidades establecidas para el título, como el propio flujo de aprendizaje o learn flow BIM. Del mismo modo reserva, incluso visualmente, aquellas áreas de conocimiento en las que, al menos en la planificación actual, la inclusión de procesos BIM no se considera ventajosa respecto a otras metodologías, o incluso inadecuadas para los objetivos docentes establecidos. Y es esta última categorización la que caracteriza el conjunto de conclusiones de esta investigación, centrada en: 1. la incuestionable necesidad de formar en conceptos y procesos BIM desde etapas muy iniciales de la formación universitaria en Arquitectura, 2. los beneficios formativos adicionales que aporta BIM en el desarrollo de competencias muy diversas contempladas en el currículum académico y 3. la especificidad del rol profesional del arquitecto que exigirá una implantación cuidadosa y ponderada de BIM que respete las metodologías de desarrollo creativo tradicionalmente efectivas, y aporte valor en una reorientación simbiótica con el diseño paramétrico y fabricación digital que permita un diseño finalmente generativo. ABSTRACT The traditional architectural design and construction procedures have proven to be deficient where process optimization is concerned, particularly when compared to other common industrial activities. The ever‐growing strife to achieve effective industrialization, both in favor of reaching greater quality levels as well as sustainable management of resources, has a better chance today than ever through a mean out of the realm of information technology, the Building Information Modelling o BIM. What may initially seem to be merely another computer program, in reality turns out to be a “process” concept that subverts many of today’s routines in architectural design and construction. Including and working with project data from the very beginning to the end of its full life cycle allows for creating a dynamic and updatable virtual reality, enabling data testing and optimizing throughout: before and during execution, all the way to the end of its lifespan. In addition, there is an opportunity to transmit complete project data efficiently, with hardly any loss or redeveloping of the manufacture chain required, which facilitates attaining a truly significant industrialization within the construction industry. In the presence of a world‐wide call for optimizing resources, along with an undeniable interest in increasing economic benefits through reducing uncertainty factors in its processes, BIM undoubtedly offers a chance for improvement as acknowledged by its imminent and mandatory implementation on the part of governments (for example United Kingdom in 2016 and Spain in 2018). The changes involved in professional roles and procedures upon incorporating BIM are highly significant and will set the course for future graduates of Architecture, Engineering and Construction disciplines (AEC) within their professions. Higher Education must respond to such needs with swiftness by incorporating this methodology into their educational standards and providing a synergetic vision that focuses on the underlying educational benefits inherent in the BIM framework. In this respect, BIM, in gathering data set under one single virtual model, offers a uniquely interesting potential. The three‐dimensional reality of the model, under continuous development and updating, provides students with a radically different graphic environment, in which partial views of elevation, section or plan that tend characteristically to be difficult to assimilate at the beginning of their studies, become mere post hoc requests to be ordered when needed directly out the virtual model. The design is always carried out on the sole model itself, independently of the working view chosen at any particular moment, with all data and data relations within construction permanently updated and fully coherent. This condensed description of the features of BIM begin to shape an important part of the educational benefits posed by BIM processes, particularly in reference to integrated design development and information management (including ITC). At the same time, it highlights the ease with which visual understanding is achieved regarding architectural elements, technology systems, their intrinsic relationships, and construction processes. In addition to this, there is the experimental development the BIM platform grants through its collaborative software: simulation of structural, energetic, and economic behavior, among others, of the virtual model according to the data inherent to the project. This doctoral dissertation presents a broad study including a wide array of research methods and issues in order to specify both the virtues and possible reservations in the use of BIM processes within the framework of a specific discipline: teaching Architecture. To do so, a literature review on BIM has been carried out, specifically concerning teaching in the discipline of Architecture, as well as an analysis of the experience of different groups of interest delimited to Universidad Europea de Madrid. The analysis of the benefits and/or limitations of using BIM has been approached through student surveys and interviews with professionals from the AEC sector, associated or not, with BIM. Various diverse educational experiences are described and academic management for experimental implementation has been analyzed. The conclusions of this study offer a synthesis for a Framework of Implementation of BIM methodology, which in order to reach greater clarity, communication ease and user‐friendliness, have been posed in an eminently graphic manner. The proposed framework proffers guidance on teaching methods conducive to the development of specific skills, taking advantage of the conceptual flexibility of the European Higher Education Area guidelines based on competencies, which naturally facilitate for the incorporation of this new teaching tool to achieve the educational objectives established by law. The global approach of the Implementation Framework put forth in this study facilitates the planning of educational actions within a common perspective: combining exceptional or vehicular BIM formats, establishing cross‐disciplinary synergies, and sharing resources, so as to purport a methodology that contributes to the assimilation of knowledge and pre‐defined competencies within the degree program, and to the flow of learning itself. At the same time, it reserves, even visually, those areas of knowledge in which the use of BIM processes is not considered necessarily an advantage over other methodologies, or even inadequate for the learning outcomes established, at least where current planning is concerned. It is this last category which characterizes the research conclusions as a whole, centering on: 1. The unquestionable need for teaching BIM concepts and processes in Architecture very early on, in the initial stages of higher education; 2. The additional educational benefits that BIM offers in a varied array of competency development within the academic curriculum; and 3. The specific nature of the professional role of the Architect, which demands a careful and balanced implementation of BIM that respects the traditional teaching methodologies that have proven effective and creative, and adds value by a symbiotic reorientation merged with parametric design and digital manufacturing so to enable for a finally generative design.

Estimate of the total volume of Svalbard glaciers, and their potential contribution to sea-level rise, using new regionally based scaling relationships

We present a set of new volume scaling relationships specific to Svalbard glaciers, derived from a sample of 60 volume–area pairs. Glacier volumes are computed from ground-penetrating radar (GPR)-retrieved ice thickness measurements, which have been compiled from different sources for this study. The most precise scaling models, in terms of lowest cross-validation errors, are obtained using a multivariate approach where, in addition to glacier area, glacier length and elevation range are also used as predictors. Using this multivariate scaling approach, together with the Randolph Glacier Inventory V3.2 for Svalbard and Jan Mayen, we obtain a regional volume estimate of 6700 ± 835 km3, or 17 ± 2 mm of sea-level equivalent (SLE). This result lies in the mid- to low range of recently published estimates, which show values as varied as 13 and 24 mm SLE. We assess the sensitivity of the scaling exponents to glacier characteristics such as size, aspect ratio and average slope, and find that the volume of steep-slope and cirque-type glaciers is not very sensitive to changes in glacier area.

Performing the personal within the organizational: Communicating professional identities through Taiwanese commercial airline pilots' personal narratives

This dissertation project explored professionalism and the performance of identities by examining Taiwanese commercial airline pilots' discursive practices in everyday life. The intentions for this project were to not only expand current knowledge of organizational communication from a critical rhetorical perspective, but to further explore the under-appreciated concept of professionalism of organizational members. Theoretically, I traced theoretical analysis in the sociology of professions and further investigated scholarship from identity research in organizational communication studies. This research agenda helped to advance communication-based understandings of the meanings and practices of professional identity as a complement to the sociological conception. I further merged a performance paradigm and critical rhetorical perspective to examine the discursive practices of organizational members and to challenge the bias of traditional textual approaches. Methodologically, I conducted ethnographic interviews with Taiwanese commercial airline pilots in order to understand how they construct their personal, social, and professional identities. Five narrative themes were identified and demonstrated in this project: (1) It takes a lot to become a commercial airline pilot, (2) Being a professional commercial airline pilot is to build up sufficient knowledge, beyond average skill, and correct attitude, (3) Pilots' resistance and dissent toward company management, (4) Popular (re)presentation influences professionalism, (5) Power and fear affect professionalism. Pilots' personal narratives were presented in performative writing and in poetic transcription to make word alive with sounds featuring their meanings. Their personal storytelling created a dialogic space to not only let pilots' voice to be heard but also revealed how identities are created within and against a larger organizational identity. Overall, this project demonstrated the interdisciplinary examination of the meanings, functions, and consequence of discursive practices in everyday professional life. It also critiqued relationships between power, domination, and resistance while reintroducing the roles of the body and materiality in the domain of professionalism, and provides ethical readings of larger and complex organizational cultures. Applying communication-oriented analysis to study professionalism indeed challenged the long time neglected phenomena regarding the power of the symbolic in sociological approaches and raised the awareness of structural, material, and bodily condition of work.

Do socioeconomic inequalities in mortality vary between different Spanish cities? a pooled cross-sectional analysis

Background: The relationship between deprivation and mortality in urban settings is well established. This relationship has been found for several causes of death in Spanish cities in independent analyses (the MEDEA project). However, no joint analysis which pools the strength of this relationship across several cities has ever been undertaken. Such an analysis would determine, if appropriate, a joint relationship by linking the associations found. Methods: A pooled cross-sectional analysis of the data from the MEDEA project has been carried out for each of the causes of death studied. Specifically, a meta-analysis has been carried out to pool the relative risks in eleven Spanish cities. Different deprivation-mortality relationships across the cities are considered in the analysis (fixed and random effects models). The size of the cities is also considered as a possible factor explaining differences between cities. Results: Twenty studies have been carried out for different combinations of sex and causes of death. For nine of them (men: prostate cancer, diabetes, mental illnesses, Alzheimer’s disease, cerebrovascular disease; women: diabetes, mental illnesses, respiratory diseases, cirrhosis) no differences were found between cities in the effect of deprivation on mortality; in four cases (men: respiratory diseases, all causes of mortality; women: breast cancer, Alzheimer’s disease) differences not associated with the size of the city have been determined; in two cases (men: cirrhosis; women: lung cancer) differences strictly linked to the size of the city have been determined, and in five cases (men: lung cancer, ischaemic heart disease; women: ischaemic heart disease, cerebrovascular diseases, all causes of mortality) both kinds of differences have been found. Except for lung cancer in women, every significant relationship between deprivation and mortality goes in the same direction: deprivation increases mortality. Variability in the relative risks across cities was found for general mortality for both sexes. Conclusions: This study provides a general overview of the relationship between deprivation and mortality for a sample of large Spanish cities combined. This joint study allows the exploration of and, if appropriate, the quantification of the variability in that relationship for the set of cities considered.

Perceived emotional intelligence, general intelligence and early professional success: predictive and incremental validity

Although the study of factors affecting career success has shown connections between biographical and other aspects related to ability, knowledge and personality, few studies have examined the relationship be-tween emotional intelligence and professional success at the initial career stage. When these studies were carried out, the results showed significant relationships between the dimensions of emotional intelligence (emotional self-awareness, self-regulation, social awareness or social skills) and the level of professional competence. In this paper, we analyze the relationship between perceived emotional intelligence, measured by the Trait Meta-Mood Scale (TMMS-24) questionnaire, general intelligence assessed by the Cattell factor "g" test, scale 3, and extrinsic indicators of career success, in a sample of 130 graduates at the beginning of their careers. Results from hierarchical regression analysis indicate that emotional intelligence makes a specific contribution to the prediction of salary, after controlling the general intelligence effect. The perceived emotional intelligence dimensions of TMMS repair, TMMS attention and sex show a higher correlation and make a greater contribution to professional success than general intelligence. The implications of these results for the development of socio-emotional skills among University graduates are discussed.
