Just-in-time (JIT) production systems are increasingly being seen as a vital way for manufacturing organizations to enhance their competitiveness. A number of commentators have suggested that this will simplify jobs and reduce employee well-being. This paper presents a conceptual framework for interpreting the effects of JIT and reports findings from a study of the impact of JIT on the content of workers'jobs and on job satisfaction and psychological strain. The introduction of JIT led to a reduction in control over work timing, an increase in production pressure, and a drop in job satisfaction. Contrary to claims in the literature, no changes were found in control over work methods, other aspects of cognitive demands and skill use, and in psychological strain. The study shows that JIT can be implemented without radical changes in job content or adverse impact in terms of employee strain, and the implications of these findings are discussed.

The primary aim of this paper is to demonstrate how technology transfer between universities and rural industries in developing countries can be achieved effectively, using independent research and advisory centres as intermediaries. It draws on a longitudinal action research study, which experiments with the process of nurturing and bridging communities of practice amongst recipients of technology and stakeholders concerned with technology diffusion, productivity and economic development. Its empirical evidence is from an academic-related, non-government intervention initiative targeting two small-scale industries, namely fish farming and coffee production, in the Cauca region of Colombia. Results demonstrate how barriers to transfer can be overcome. The intervention is considered as instrumental; its key components and outcomes are discussed in detail. © 2012 Elsevier Ltd.

The National Institute for Transport and Logistics (NITL) is Ireland’s centre of excellence for supply chain management (SCM). As part of its mission to promote the development of supply chain expertise in Irish business, it designs and delivers executive modular learning programmes. In 2004, as part of a drive to create more flexible learning opportunities for course participants, NITL designed and implemented an eLearning programme, which involved converting traditionally tutored modules to online modules. This paper describes the rationale behind this initiative and the significance of technology as an enabling tool for executive education, as well as detailing the design and implementation processes for the pilot module. The paper concludes with a critique of the expected and actual benefits realised, as well as future development considerations.

Macroeconomic developments, such as the business cycle, have a remarkable influence on firms and their performance. In business-to-business (B-to-B) markets characterized by a strong emphasis on long-term customer relationships, market orientation (MO) provides a particularly important safeguard for firms against fluctuating market forces. Using panel data from an economic upturn and downturn, we examine the effectiveness of different forms of MO (i.e., customer orientation, competitor orientation, interfunctional coordination, and their combinations) on firm performance in B-to-B firms. Our findings suggest that the impact of MO increases especially during a downturn, with interfunctional coordination clearly boosting firm performance and, conversely, competitor orientation becoming even detrimental. The findings further indicate that both the role of MO and its most effective forms vary across industry sectors, MO having a particularly strong impact on performance among B-to-B service firms. The findings of our study provide guidelines for executives to better manage performance across the business cycle and tailor their investments in MO more effectively, according to the firm's specific industry sector.

Purpose: The focus of this paper is the evolution of supply chain management (SCM) and logistics, as well as of the relationship between them. Its purpose is to generate deep insights into practice, particularly in relation to the fundamental issue of how practitioners define these key terms and phrases. Research approach: A largely qualitative study which involved in depth interviews with managers from two third party logistics providers (3PLs)/distributors, two retailers and two manufacturers from the United Kingdom. This interview protocol is based on the template used in a previous study published over a decade ago. Findings and originality: The data collected during the focussed interviews in the United Kingdom is contrasted with results from the earlier study. The findings suggest that there is variation between practitioners particularly in relation to what SCM is specifically concerned with. This variation mirrors to a large extent the differing orientations and emphases evident in the many theoretical definitions of SCM that have been proposed in recent decades. Research impact: The authors introduced the concept of refined replication in SCM research. This allows previous research to be built upon in order to test understanding of SCM theory and its practical implementation among SCM professionals in the United Kingdom. Practical impact: A profile of SCM understanding and adoption by firms in the United Kingdom is presented .

The extant literature on workplace coaching is characterised by a lack of theoretical and empirical understanding regarding the effectiveness of coaching as a learning and development tool; the types of outcomes one can expect from coaching; the tools that can be used to measure coaching outcomes; the underlying processes that explain why and how coaching works and the factors that may impact on coaching effectiveness. This thesis sought to address these substantial gaps in the literature with three linked studies. Firstly, a meta-analysis of workplace coaching effectiveness (k = 17), synthesizing the existing research was presented. A framework of coaching outcomes was developed and utilised to code the studies. Analysis indicated that coaching had positive effects on all outcomes. Next, the framework of outcomes was utilised as the deductive start-point to the development of the scale measuring perceived coaching effectiveness. Utilising a multi-stage approach (n = 201), the analysis indicated that perceived coaching effectiveness may be organised into a six factor structure: career clarity; team performance; work well-being; performance; planning and organizing and personal effectiveness and adaptability. The final study was a longitudinal field experiment to test a theoretical model of individual differences and coaching effectiveness developed in this thesis. An organizational sample of 84 employees each participated in a coaching intervention, completed self-report surveys, and had their job performance rated by peers, direct reports and supervisors (a total of 352 employees provided data on participant performance). The results demonstrate that compared to a control group, the coaching intervention generated a number of positive outcomes. The analysis indicated that coachees’ enthusiasm, intellect and orderliness influenced the impact of coaching on outcomes. Mediation analysis suggested that mastery goal orientation, performance goal orientation and approach motivation in the form of behavioural activation system (BAS) drive, were significant mediators between personality and outcomes. Overall, the findings of this thesis make an original contribution to the understanding of the types of outcomes that can be expected from coaching, and the magnitude of impact coaching has on outcomes. The thesis also provides a tool for reliably measuring coaching effectiveness and a theoretical model to understand the influence of coachee individual differences on coaching outcomes.

The purpose of this study was to aid in understanding the relationship between current Reading report card grading practices and standards-based state standardized testing results in Reading and factors associated with the alignment of this relationship. Report card and Florida Comprehensive Assessment Test (FLAT) data for 2004 were collected for 1064 third grade students in nine schools of one feeder pattern in Florida's Miami-Dade County Public Schools. A Third Grade Teacher Questionnaire was administered to 48 Reading teachers. The questionnaire contained items relating to teachers' education, teaching experience, grading practices, and beliefs about the FCAT, instructional Reading activities, methods, and materials. ^ Findings of this study support a strong relationship between report card grades and FCAT Reading achievement levels. However, individual school correlational analysis showed significant differences among schools' alignment measures. Higher teacher alignment between grades and FCAT levels was associated with teachers spending more time on individualized methods of Reading instruction and to teachers feeling there was not enough time to teach and help individual students. Lower teacher alignment of grades and achievement levels was associated with teachers taking homework into account in the final Reading grade. Teacher alignment of grades and achievement levels was not associated with teacher beliefs concerning the FCAT, instructional activities in Reading and Language Arts, the Reading program used, the model of delivery of the Reading program, instruction or type of instructional planning done by the teachers. ^ This study highlights the need for further investigations related to determining additional teacher factors that may affect the alignment relationship between report card grades and standards-based state standardized testing results. ^

The prevalence of waterpipe smoking exceeds that of cigarettes among adolescents in the Middle East where waterpipe is believed as less harmful, less addictive and can be a safer alternative to cigarettes. This dissertation tested the gateway hypothesis that waterpipe can provide a bridge to initiate cigarette smoking, identified the predictors of cigarette smoking progression, and identified predictors of waterpipe smoking progression among a school-based sample of Jordanian adolescents (mean age ± SD) (12.7 ±0.61) years at baseline. Data for this research have been drawn from Irbid Longitudinal Study of smoking behavior, Jordan (2008-2011). The grouped-time survival analysis showed that waterpipe smoking was associated with a higher risk of cigarette smoking initiation compared to never smokers (P < 0.001) and this association was dose dependent (P < 0.001). Predictors of cigarette smoking progression were peer smoking and attending public schools for boys, siblings’ smoking for girls, and the urge to smoke for both genders. Predictors of waterpipe smoking progression were enrollment in public schools, frequent physical activity, and low refusal self-efficacy for boys, ever smoking cigarettes, friends’ and siblings’ waterpipe smoking for girls. Awareness of harms of waterpipe among boys and seeing warning labels on the tobacco packs by girls were protective against waterpipe smoking progression. In Conclusion, waterpipe can serve as a gateway to cigarette smoking initiation among adolescents. Waterpipe and cigarette smoking progressions among initiators were solely family-related among girls, and mainly peer-related among boys. The unique gender differences for both cigarette and waterpipe smoking among Jordanian adolescents in Irbid call for cultural and gender-specific smoking prevention interventions to prevent the progression of smoking among initiators.

El drama migratorio del cual está siendo Europa testigo en estas últimas semanas es en parte el resultado de una falta de políticas comunitarias en relación a este tema, hecho del cual, en los últimos años, se han hecho eco multitud de medios. Europa, y en especial los países del Mediterráneo, ha experimentado un incremento sustancial en el número de inmigrantes que llegan a sus costas en condiciones cada vez más deplorables y arriesgando gravemente su integridad física. Este hecho está principalmente motivado por el aumento y la intensidad de los conflictos bélicos en países de África y Oriente próximo. En el caso de Malta, un diminuto archipiélago ubicado entre los territorios de Libia y Sicilia, el cambio en la tendencia migratoria que se produjo en 2002 le hizo pasar de ser un país de emigrantes a un país receptor de inmigrantes. Este cambio dio como resultado la aparición de grupos y partidos anti-inmigración, como Azzjoni Nazzjonali, y de un sentimiento de preocupación frente a la llegada de inmigrantes que crece de manera constante según se refleja en encuestas europeas (véase Eurobarometer 82-83). Desde el punto de vista lingüístico, el discurso discriminatorio empleado por los medios de comunicación, organismos y figuras políticas ha sido ampliamente estudiado dentro de la rama del Análisis Crítico del Discurso (Charteris-Black, 2006; Fairclough, 1989, Reisigl & Wodak, 2001; Santa Ana, 1999; Van Dijk, 1984, 1992, 1999, 2000, 2006, Van Leeuwen & Wodak, 1999). En los últimos años, se ha potenciado el uso de un enfoque cognitivo en el análisis de este tipo de discursos. Dicho enfoque utiliza elementos tomados de la lingüística cognitiva para explicar cómo la representación de eventos y participantes en el discurso atiende, o está motivada por la conceptualización mental de dichos eventos y participantes (Charteris-Black, 2006; Hart, 2011; Musolff, 2012; Núñez-Perucha, 2011; O’Brien, 2003; Santa Ana, 1999; Van Dijk, 1992, 1998, 1999, 2000, 2006; Wodak, 2006). El Análisis Crítico del Discurso es una disciplina cuyo principal objetivo es analizar cómo ciertos fenómenos sociales que se basan en relaciones de abuso de poder y dominación se representan en el discurso de las denominadas élites (Van Dijk, 2001). Muchos de estos discursos atienden a lo que en lingüística se ha denominado discurso de discriminación, en donde un grupo dominante ejerce poder sobre otro mediante el uso de diversas herramientas discursivas. Generalmente, estos estudios sobre discursos de discriminación se han centrado en fenómenos como el machismo o el racismo. Dentro de este último campo, cabe destacar el trabajo de Van Dijk en el análisis del discurso del racismo y del discurso de la inmigración (Van Dijk, 1992, 1999, 2000, 2001, 2006). El presente trabajo se centra en analizar cómo la prensa maltesa ha representado el fenómeno de la inmigración y a los inmigrantes desde 2005 hasta 2015. Dentro de esta línea temporal, se presta especial atención al día 2 de abril de 2013. Esta es la fecha en la que la Associated Press, una organización de prensa independiente con subscriptores alrededor del mundo, decidió incluir un importante cambio léxico en su manual de estilo. El motivo del mismo era modificar el uso del adjetivo “ilegal” recomendando su uso para referirse exclusivamente a acciones (ej. Inmigración ilegal) pero nunca para referirse a individuos (ej. Inmigrante ilegal). Nuestro estudio pretende identificar hasta qué punto esta medida se ha puesto en práctica en los periódicos malteses y qué repercusiones ha tenido su incorporación en la representación de los inmigrantes y la inmigración. Para ello, se ha seleccionado como caso de estudio uno de los periódicos en lengua inglesa más leídos en el archipiélago, Times of Malta. El estudio se ha centrado en el análisis de un total de treinta artículos de opinión repartidos de manera homogénea (quince y quince) en dos corpus. El primer corpus contiene artículos pertenecientes a un periodo de tiempo que va desde 2005 hasta la fecha en la cual el cambio léxico de la Associated Press fue publicado, es decir, el 2 de abril de 2013. Por otro lado, el segundo corpus contiene artículos desde el 2 de abril de 2013 hasta mediados de 2015. Para agilizar y facilitar el análisis de los artículos, se ha hecho uso del programa llamado WordSmith Tools, el cual está especializado en el trabajo con corpus. Este programa se utilizó principalmente para analizar la representación semántica de los distintos participantes y eventos. Los resultados del análisis demuestran que el periódico ha aplicado el cambio léxico sugerido por la Associated Press al no encontrarse ningún ejemplo de “inmigrante ilegal” o “migrante ilegal” a partir del 2 de abril de 2013. En estos mismos resultados también se aprecia una representación más positiva de la figura del inmigrante en el segundo corpus, dónde el inmigrante abandona la categoría léxica de “criminal” para comenzar a ser visto cada vez más como la víctima. También a nivel léxico, se puede observar cómo los autores tienden a usar cada vez más el término “migrante” en lugar de “inmigrante”. A pesar de que este último continúa siendo el término más utilizado para referirse a la persona que llega desde otro país, el significativo incremento del uso de la palabra “migrante” en el segundo corpus es llamativo y puede deberse a que la palabra “inmigrante” haya adquirido connotaciones negativas por su repetido uso junto al adjetivo “ilegal”. De entre las estrategias discursivas empleadas en la representación de la sociedad maltesa, cabe destacar dos. Por un lado, tenemos el uso de la victimización, mediante la cual la población maltesa aparece como una víctima frente a la inmigración, que es vista como una amenaza, al mismo tiempo que Malta es también víctima de la falta de apoyo internacional. En segundo lugar, es también común encontrar artículos en donde el autor destaca las cualidades positivas de la sociedad maltesa, especialmente su generosidad. Esta última estrategia es lo que Van Dijk denomina national self-glorifiation (2000:220; 2006:738). En cuanto al uso de las metáforas, el cambio es menos significativo. En general, ambos corpus muestran ejemplos de metáforas en las que el inmigrante aparece conceptualizado como parte de un fenómeno natural incontrolable, un invasor o un organismo dispuesto a infectar o dañar de algún modo el país. En el segundo corpus, sin embargo, desaparecen las metáforas en las que el inmigrante se percibe como un animal inferior, que sí aparecían en el primer corpus. Esto supone un cambio positivo. Hasta este punto hemos resumido los cambios en la representación de los inmigrantes. Respecto al modo en el cual el fenómeno de la inmigración aparece representado en los periódicos, también encontramos cambios importantes. A nivel léxico, el cambio que mencionábamos relativo a los términos “inmigrante” y “migrante” también se produce a la hora de nombrar este fenómeno social. De este modo, la palabra “migración” es más usada en el segundo corpus que en el primero, aunque sigue ocupando el segundo lugar por detrás de la palabra “inmigración”. En cuanto a los contenidos, se puede observar un cambio positivo hacia una mayor concienciación social. Por ejemplo, vemos cómo en el segundo corpus en ocasiones se pide una respuesta estatal a temas como la integración de los inmigrantes o el racismo entre la sociedad, mientras que en el primer corpus la integración era una labor del inmigrante y el racismo era un tema incómodo. En el segundo corpus también encontramos la queja más clara hacia el uso de centros de detención en la isla. En el primer corpus, aunque algunos autores manifestaban su disconformidad con las condiciones en las cuales los inmigrantes vivían dentro de los centros de detención, todos asumían que tener dichos centros era una medida necesaria. Esta especie de consenso social y político acerca del uso de centros de detención se consigue mediante el empleo de herramientas discursivas que representen la inmigración como una amenaza de la cual hay que protegerse (negative other-presentation Van Dijk, 2000:221; 2006:738). En resumen, podemos decir que este trabajo muestra una progresión en el discurso de inmigración en Malta hacia una representación más positiva y amable del inmigrante y de la inmigración. Aunque las limitaciones de este estudio hacen imposible establecer una relación única y directa entre los cambios experimentados por el periódico y el cambio léxico sugerido por la Associated Press, lo cierto es que la descriminalización de los inmigrantes a nivel léxico (mediante la supresión de términos como “ilegal” o “detenidos”) ha influido de manera positiva en el tono y la forma en que este periódico se refiere al fenómeno social de la inmigración

The expansion of the specialty of sports and exercise medicine (SEM) is a relatively recent development in the medical community and the role of the SEM specialist continues to evolve and develop. The SEM specialist is ideally placed to care for all aspects of physical activity not only in athletes but also in the general population. As an advocate for physical activity the SEM specialist plays a broad role in advising safe effective sports and recreation participation; screening for disease related to sports participation; examining and contributing to the evidence behind treatment strategies and evaluating any potential negative impact of sports injury prevention measures. In this thesis I will demonstrate the breadth of the role the Sports and Exercise Medicine Specialist from epidemiology to in-depth examination of treatment strategies. In Chapter 2, I examined the epidemiology of sports and recreation related injury (SRI) in Ireland, an area that has previously been poorly studied. We report on 3,172 SRI (14% of total presentations) presentations to the ED over 6 months. Paediatric patients (4-16 yrs) were over represented comprising 39.9% of all SRI presentation compared to 16% of total ED presentations and 18% of the general population. These injuries were serious (32% fractures) and though 49% of injuries occurred during organised competition/practice, 41.5% occurred during recreation-most often at home. In Chapter 3, I examined risk factors associated with hand injury in hurling. The previous chapter highlighted the importance of a firm evidence base underpinning treatment strategies. When measures to improve welfare are introduced not only must potential benefits be measured, so too must potential unwanted adverse outcomes. In this study I examined a cohort of adult hurlers who had presented to the ED with a hurling related injury in order to highlight the variables associated with hand injury in this population. I found the athletes who wore a helmet were far more likely (OR 3.15 95% CI (1.51-6.56) p= 0.002) to suffer a hand injury than athletes who did not. Very few of those interviewed (4.9%) used hand protection compared to 65% who used helmet and faceguard. The introduction of the helmet and faceguard in hurling has undeniably decreased the incidence of head and face injury in hurling. However in tandem with this intervention several observational studies have demonstrated an increase in the occurrence of hurling related hand injuries. This study highlights the importance of being cognisant of unanticipated or unintended consequences when implementing a new treatment or intervention. In Chapter 4, I examined the role of population screening as applied to sport and exercise. This is a controversial area –cardiac screening in the exercising population has been the subject of much debate. Specifically I define the prevalence of exercise induced bronchoconstriction (EIB) using a specifically designed sports specific field-testing protocol. In this study I found almost a third (29%) of a full international professional rugby squad had confirmed asthma or EIB, as compared with 12-15% of the general population. Despite regular medical screening, 5 ‘new’ untreated cases (12%) were elicited by the challenge test and in the group already on treatment for asthma/EIB; over 50% still displayed EIB. In Chapter 5, I examined the evidence supporting current treatment options for iliotibial band friction syndrome (ITBFS). The practice of sports medicine has traditionally been ‘eminence based’ rather than ‘evidence based’. This may be problematic as some of these practices are based upon flawed principles- for example the treatment of iliotibial band friction syndrome (ITBFS). In this chapter, using cadaveric and biomechanical studies I expand upon the growing base of evidence clarifying the anatomy and biomechanics of the area-thereby re-examining the principles on which current treatments are based. The role of the SEM specialist is broad; we chose to examine specific examples of some of the roles that they execute. An understanding of the epidemiology of SRI presenting to the ED has implications for individual patients, sports governing bodies and health resource utilisation. Population screening is an important tool in health promotion and disease prevention in the general population. Screening in SEM may have similar less well-recognised benefits. The SEM specialist needs to be conversant in screening for medical conditions concerning physical activity. A comprehensive understanding of the pathophysiology of a disease is required for its diagnosis and treatment. Due to the ongoing evolution of SEM many treatments are eminence-based rather than evidence‐based practice. Continued re-examination of the fundamentals of current practice is essential. An awareness of potential unwanted side effects is essential prior to the introduction of any new treatment or intervention. The SEM specialist is ideally placed to advise sports governing bodies on these issues prior to and during their implementation.

Since submission of the draft report to the OECD‐LEED Program on 30 June 2007, a unique seven‐years retrospective study of the unemployed high technology workers was released by Statistics Canada.1 Drawing upon Statistics Canada’s confidential Longitudinal Worker File – itself constructed from four administrative data sources that linked Records of Employment and tax filer information by the Social Insurance Number and firm‐level data by a company identifier – this study was able to identify and trace the re‐employment of those permanently laid off in the high‐tech industry by location. The findings are stunning.

Previous research claims that there has been a narrowing of distance between the Swedish political parties. Typically, such research into political distance has primarily focused on studying voters rather than the political parties themselves. In this article, the author conducts a longitudinal analysis of Comparative Manifesto Project data to determine if, and to what extent, the political parties have converged ideologically on a Left-Right continuum in the period 1991-2010. After first unraveling the concept of political distance, the author moves on to explain why the ideological dispersion of political parties is an important and consequential characteristic within party systems. Furthermore, the author argues that the Left-Right ideological scale continues to be a highly useful model with which to conceptualize and study this characteristic. The author then discusses the methodological approach and explains why quantitative manifesto data, often overlooked in favor of voter interview data, is deemed a valid and reliable material for measuring the ideological positions of political parties. The findings are that there indeed have been over all tendencies of ideological convergence between the blocs and that, in terms of how political parties are dispersed on a Left- Right ideological continuum, by 2010, the Swedish party system (the Sweden Democrats excluded) had become much less polarized than it had been in 1991.

Most Australian banana production occurs on the north-eastern tropical coast between latitudes 15-18°S, and can experience summer cyclone activity. Damage from severe tropical cyclones has serious impact on banana-based livelihoods. The most significant impacts include immediate loss of production and income for several months, the region-wide synchronization of cropping and the expense of rehabilitating affected plantations. Severe tropical cyclones have directly affected the main production region twice in recent years Tropical Cyclone (TC) Larry (Category 4) in March 2006 and TC Yasi (Category 5) in February 2011. Based on TC Larry experiences, pre- and post-cyclone farm practices were developed to reduce these impacts in future cyclonic events. The main pre-cyclone farm practice focused on maintaining production units and an earlier return to fruit production by partially or completely removing the plant canopy to reduce wind resistance. Post-cyclone farm practices focused on managing the industry-wide crop synchronization using crop timing techniques to achieve a staggered return to cropping by scheduling production to provide continuous fruit supply. With TC Yasi in 2011, some banana producers implemented these practices, allowing them to examine their effectiveness in reducing cyclonic impacts. Additional research and development activities were conducted to refine our understanding of their effectiveness and improve their application for future cyclonic events. Based on these activities and farm-based observations, suggested practice-based management strategies can be developed to help reduce the impact of severe tropical cyclones in the future. Canopy removal maintained banana plants as productive units, and provided earlier but smaller bunches, generating earlier-than-expected income. Queensland producers expressed willingness to adopt canopy removal for future cyclone threats where appropriate, despite its labor-intensiveness. Mechanization would allow larger scale adoption. Implementing a staggered cropping program successfully achieved a consistent, continuous fruit supply after a cyclone impact. Both techniques should be applicable to other cyclone-prone regions.
