Modeling impact assessment of transport policies through a multiregional input-output integrated approach

El objetivo de esta investigación es desarrollar una metodología para estimar los potenciales impactos económicos y de transporte generados por la aplicación de políticas en el sector transporte. Los departamentos de transporte y otras instituciones gubernamentales relacionadas se encuentran interesadas en estos análisis debido a que son presentados comúnmente de forma errónea por la insuficiencia de datos o por la falta de metodologías adecuadas. La presente investigación tiene por objeto llenar este vacío haciendo un análisis exhaustivo de las técnicas disponibles que coincidan con ese propósito. Se ha realizado un análisis que ha identificado las diferencias cuando son aplicados para la valoración de los beneficios para el usuario o para otros efectos como aspectos sociales. Como resultado de ello, esta investigación ofrece un enfoque integrado que incluye un modelo Input-Output de múltiples regiones basado en la utilidad aleatoria (RUBMRIO), y un modelo de red de transporte por carretera. Este modelo permite la reproducción con mayor detalle y realismo del transporte de mercancías que por medio de su estructura sectorial identifica los vínculos de las compras y ventas inter-industriales dentro de un país utilizando los servicios del transporte de mercancías. Por esta razón, el modelo integrado es aplicable a diversas políticas de transporte. En efecto, el enfoque se ha aplicado para estudiar los efectos macroeconómicos regionales de la implementación de dos políticas diferentes en el sistema de transporte de mercancías de España, tales como la tarificación basada en la distancia recorrida por vehículo-kilómetro (€/km) aplicada a los vehículos del transporte de mercancías, y para la introducción de vehículos más largos y pesados de mercancías en la red de carreteras de España. El enfoque metodológico se ha evaluado caso por caso teniendo en cuenta una selección de la red de carreteras que unen las capitales de las regiones españolas. También se ha tenido en cuenta una dimensión económica a través de una tabla Input-Output de múltiples regiones (MRIO) y la base de datos de conteo de tráfico existente para realizar la validación del modelo. El enfoque integrado reproduce las condiciones de comercio observadas entre las regiones usando el sistema de transporte de mercancías por carretera, y que permite por comparación con los escenarios de políticas, determinar las contribuciones a los cambios distributivos y generativos. Así pues, el análisis estima los impactos económicos en cualquier región considerando los cambios en el Producto Interno Bruto (PIB) y el empleo. El enfoque identifica los cambios en el sistema de transporte a través de todos los caminos de la red de transporte a través de las medidas de efectividad (MOEs). Los resultados presentados en esta investigación proporcionan evidencia sustancial de que en la evaluación de las políticas de transporte, es necesario establecer un vínculo entre la estructura económica de las regiones y de los servicios de transporte. Los análisis muestran que para la mayoría de las regiones del país, los cambios son evidentes para el PIB y el empleo, ya que el comercio se fomenta o se inhibe. El enfoque muestra cómo el tráfico se desvía en ambas políticas, y también determina detalles de las emisiones de contaminantes en los dos escenarios. Además, las políticas de fijación de precios o de regulación de los sistemas de transporte de mercancías por carretera dirigidas a los productores y consumidores en las regiones promoverán transformaciones regionales afectando todo el país, y esto conduce a conclusiones diferentes. Así mismo, este enfoque integrado podría ser útil para evaluar otras políticas y otros países en todo el mundo. The purpose of this research is to develop a methodological approach aimed at assessing the potential economic and transportation impacts of transport policies. Transportation departments and other related government parties are interested in such analysis because it is commonly misrepresented for the insufficiency of data and suitable methodologies available. This research is directed at filling this gap by making a comprehensive analysis of the available techniques that match with that purpose. The differences when they are applied for the valuation of user benefits or for other impacts as social matters have been identified. As a result, this research presents an integrated approach which includes both a random utility-based multiregional Input-Output model (RUBMRIO), and a road transport network model. This model accounts for freight transport with more detail and realism because its commodity-based structure traces the linkages of inter-industry purchases and sales that use freight services within a given country. For this reason, the integrated model is applicable to various transport policies. In fact, the approach is applied to study the regional macroeconomic effects of implementing two different policies in the freight transport system of Spain, such as a distance-based charge in vehicle-kilometer (€/km) for Heavy Goods Vehicles (HGVs), and the introduction of Longer and Heavier Vehicles (LHVs) in the road network of Spain. The methodological approach has been evaluated on a case by case basis considering a selected road network of highways linking the capitals of the Spanish regions. It has also considered an economic dimension through a Multiregional Input Output Table (MRIO) and the existing traffic count database used in the model validation. The integrated approach replicates observed conditions of trade among regions using road freight transport systems that determine contributions to distributional and generative changes by comparison with policy scenarios. Therefore, the model estimates economic impacts in any given area by considering changes in Gross Domestic Product (GDP), employment (jobs), and in the transportation system across all paths of the transport network considering Measures of effectiveness (MOEs). The results presented in this research provide substantive evidence that in the assessment of transport policies it is necessary to establish a link between the economic structure of regions and the transportation services. The analysis shows that for most regions in the country, GDP and employment changes are noticeable when trade is encouraged or discouraged. This approach shows how traffic is diverted in both policies, and also provides details of the pollutant emissions in both scenarios. Furthermore, policies, such as pricing or regulation of road freight transportation systems, directed to producers and consumers in regions will promote different regional transformations across the country, and this lead to different conclusions. In addition, this integrated approach could be useful to assess other policies and countries worldwide.

Evaluation of Development Projects: a Process-Centered Approach in the Outskirts of Lima, Peru.

Development cooperation projects work with people involved in processes of change and social transformation. While the main objective of the intervention is the development process itself, the project?s quality will be determined by the way of implementing it. Its success lies in the sustainability of the generated processes and the connection with them by the involved actors. The evaluation analyses both aspects. This article examines the evaluation, under a process approach, of a project on urban agriculture in Lima (Peru). The results show that the use of this approach, which combines different evaluation tools, allows the identification and analysis of the processes with the involved members, providing a better understanding of the real sustainability of the results.

A random utility based multiregional input-output approach to estimate the impact of a new highway on the regional distribution of jobs

This paper addresses the economic impact assessment of the construction of a new road on the regional distribution of jobs. The paper summarizes different existing model approaches considered to assess economic impacts through a literature review. Afterwards, we present the development of a comprehensive approach for analyzing the interaction of new transport infrastructure and the economic impact through an integrated model. This model has been applied to the construction of the motorway A-40 in Spain (497 Km.) which runs across three regions without passing though Madrid City. This may in turn lead to the relocation of labor and capital due to the improvement of accessibility of markets or inputs. The result suggests the existence of direct and indirect effects in other regions derived from the improvement of the transportation infrastructure, and confirms the relevance of road freight transport in some regions. We found that the changes in regional employment are substantial for some regions (increasing or decreasing jobs), but a t the same time negligible in other regions. As a result,the approach provides broad guidance to national governments and other transport-related parties about the impacts of this transport policy.

Influencia de un nuevo marco jurídico en la competitividad del sistema portuario español

El sistema portuario español movió en el año 2013 aproximadamente 458,54 millones de toneladas, 13,8 millones de TEUs, con un total de 131.128 buques que accedieron a puerto para el conjunto de las 28 Autoridades Portuarias. Con el 62% de las exportaciones y el 86% de las importaciones realizadas por vía marítima, una rentabilidad del 2,34 %, muy cerca del objetivo del 2,5 % de rentabilidad media annual establecida legalmente, y una cifra de negocios aproximada de 1.028 millones de euros equivalentes al 1,1 % del PIB que genera un empleo directo e indirecto vinculado de 145.000 personas, concluimos que estamos hablando de un sector estratégico para la economía del país. Desde hace décadas, en muchos puertos del mundo se han venido desarrollando terminales “hub” o de concentración y distribución de cargas. Las navieras concentran entre este tipo de terminales sus líneas transoceánicas con buques de enormes dimensiones y capacidad de carga para producir los tránsitos de contenedores desde estas líneas a otras líneas llamadas “feeder”, con buques de menor tamaño que enlazan el “hub” con los puertos de su área marítima de influencia. La excepcional ubicación geoestratégica de España, con aproximadamente ocho mil kilómetros de costa, ha originado que los puertos españoles de mayor dimensión aspiren a incorporarse a esta red marítima internacional de contenedores y determina que en nuestro sistema portuario los movimientos de contenedores de tránsito tengan gran importancia. Sin embargo, la crisis económica ha tenido un efecto decisivo en el sector marítimo, determinando una lucha feroz entre todos los puertos, nacionales e internacionales, por captar este tipo de tráficos, lo que origina una búsqueda de las compañías navieras de puertos cada vez más eficientes en términos calidad/coste del servicio. La entrada en vigor del Texto Refundido de la Ley de Puertos y la piedra angular de su reforma, la Ley 33/2010, plantea como objetivo principal la mejora de la competitividad del sistema portuario español y liderar su recuperación, ofreciendo unas condiciones de entorno favorables a los puertos españoles que acaben por incentivar la captación de tráficos e inversión privada a través de una oferta de servicios e infraestructura de calidad y a precios competitivos que consoliden su posición dentro del tráfico marítimo mundial. Surge, por tanto, la conveniencia de investigar la influencia de las medidas propuestas por dicha norma legal y las soluciones ofrecidas a las demandas de un sector considerado estratégico para la economía del país, y cuya resolución se considera imprescindible para consolidar su recuperación. Por eso, se han analizado los aspectos más importantes de la reforma mediante la realización de un resumen ejecutivo y se ha estudiado la influencia de las medidas que incorpora desde el punto de vista de tres factores, que previamente se han considerado como fundamentales para la recuperación del sistema portuario español, y que históricamente habían sido demandados por el mismo, como son, en primer lugar, un progresivo sistema de flexibilización tributaria que permitiera a los puertos españoles ganar en términos de competitividad respecto a otros modelos portuarios mucho más flexibles en materia tarifaria, en segundo lugar, una necesaria liberalización del régimen de prestación de los servicios portuarios que posibilite el libre acceso a cualquier interesado en su prestación y, en último lugar, el progresivo abaratamiento de los costes inherentes a dichos servicios, fundamentalmente la manipulación de mercancías. Con posterioridad se ha investigado el trámite parlamentario al que se ha sometido la ley, fruto del enorme consenso alcanzado entre las dos principales fuerzas políticas del país, que determinó que se presentaran más de 700 enmiendas al proyecto original, y en algunos casos, se ha prestado especial atención a determinadas enmiendas que se consideran, en opinión de este investigador, novedosas y aventuradas, razón por la cual quizás no fueron incorporadas definitivamente al texto legal. Y se han analizado las principales demandas y aportaciones extraídas de la Sesión Informativa sobre la tramitación del entonces proyecto de ley ofrecida por la Comisión de Fomento del Congreso de los Diputados a los principales representantes del sector, comunidad portuaria, universidad y sindicatos. Siendo conscientes de la incidencia que tiene el servicio portuario de manipulación de mercancías en el paso de la mercancía por el puerto, se ha hecho una referencia concreta al peculiar régimen jurídico y laboral del personal vinculado al servicio. Avanzamos que las características de la relación laboral especial, y su peculiar régimen jurídico, con una dualidad de relaciones laborales, tiene una influencia decisiva en la nómina del trabajador que se repercute en los usuarios del servicio, fundamentalmente el naviero y el operador de la terminal, que en definitiva, incide en la competitividad del puerto. Y se ha constatado el auge aperturista de numerosas legislaciones portuarias europeas, prestando especial atención al proyecto frustrado de liberalización de los servicios portuarios en la Unión Europea de la conocida como Directiva Loyola de Palacio del año 2003 y al Libro Blanco de Transportes del año 2011. Así como a las deficiencias advertidas por el Dictamen de la Comisión Europea de fecha 27/09/2012 en relación al régimen jurídico del servicio portuario de manipulación de mercancías, que lo considera disconforme y contrario con las normas de libertad de establecimiento en Europa y que amenaza con una previsible reforma unilateral de la legislación portuaria española, a instancias europeas. Bajo este planteamiento, se ha procedido a analizar el marco de prestación de dichos servicios desde el punto de vista de la propia comunidad portuaria. Inicialmente, a través de un estudio de fuerzas de la competitividad del sector de los servicios portuarios en el sistema portuario español que nos permitirá trazar un mapa estratégico del mismo a través del “Modelo de las Cinco Fuerzas de Porter” concluyendo, que el poder de los prestadores de servicios portuarios como proveedores de los mismos, fundamentalmente en la manipulación de mercancías, es máximo, con un único colectivo, los estibadores portuarios, que al amparo de la normativa legal vigente tienen la exclusividad de su prestación. Dichas circunstancias restan competitividad al sistema frente a alternativas portuarias más flexibles y desincentivan la inversión privada. Y, en segundo lugar, mediante un proceso participativo en distintas encuestas sobre el modelo legislativo y sobre el marco formativo del sector con los propios agentes afectados dentro de la comunidad portuaria, desde la triple perspectiva de la vertiente pública que representan las Autoridades Portuarias, como gestores de las infraestructuras, la vertiente privada que representan los usuarios y prestadores de servicios, como principal cliente del puerto y desde el punto de vista de la propia mano de obra portuaria materializada en la representación sindical de dichos trabajadores. Los resultados nos permitirán concluir, respectivamente, la incidencia del servicio portuario mercancía por el puerto, por representar más de la mitad de los costes. Así como la aspiración de los trabajadores adscritos a dicho servicio de consolidar un título formativo que unifique y potencie su capacitación profesional, circunstancia esta última, también demandada por toda comunidad portuaria. Analizadas las conclusiones extraídas en cada una de las líneas de investigación se han detectado una serie de ineficiencias dentro del mismo que dicho marco regulador no ha sabido resolver, por lo que se ha considerado la conveniencia de formular, como herramienta de ayuda a gestores del sistema portuario español, una relación de medidas que, en opinión de este investigador, se consideran necesarias para mejorar el régimen de prestación de los servicios portuarios y se ha propuesto un borrador de modificación del actual Texto Refundido que pueda servir de base para materializar una futura reforma legal. Las conclusiones obtenidas en la investigación deben sentar las bases de una profunda reflexión sobre la necesidad de encaminar, como alternativa a una previsible modificación a instancias europeas, una reforma legal que decididamente apueste por la competitividad del sistema portuario español desde el punto de vista de la liberalización de servicios, el abaratamiento de los costes de la estiba y la necesaria profesionalización de los trabajadores adscritos al servicio portuario de manipulación de mercancías. During 2013 the Spanish Port System moved nearly 458,54 million tons of freight, 13,8 million TEUs, involving a total of 131.128 ships for the 28 existing Port Authorities. With 62% of exports and 86% of imports made through sea transportation, a 2,34% profit, close to the 2,5% average annual profit goal legally established, revenues of 1.028 million € equivalent to a 1.1% of Spain’s GDP and a figure of 145.000 people a directly or indirectly employed we can conclude that maritime industry is undoubtedly one of the strategic and key sectors for the country’s economy. Since several decades many ports in the world have been increasingly developing “Hub” terminals, those which concentrate and distribute freight. Shipping companies place among these type of terminals their transoceanic sea liners along with huge dimension & capacity ships to make the container transit from these liners to other called “feeder” which are smaller freight ships that connect the “hub” with the ports within its maritime area of influence. Spain’s exceptional geostrategic location with over 8.000 km of coastline has originated that those big dimension Spanish ports aspire to become a part of a container international maritime network which also determines that transit container move is key within our port system. Nevertheless the economic crisis has had a decisive impact on the maritime sector originating a fierce battle between all ports, national and international ones, all of them fight against each other to catch this type of maritime traffic which triggers an ongoing shipping companies search in cost/service quality efficient ports. The cornerstone of the Restated Text of Port Law is Law 33/2010, which lays out as main goal the Spanish Port System competitiveness improvement and lead its recovery offering favorable environment conditions to Spanish ports which help encourage maritime traffic attraction and private investment through a wide offer of services, quality of infrastructure and competitive prices which can consolidate its positioning within the world’s maritime traffic. It is therefore key to investigate the influence of the measures proposed by the above mentioned law and also the solutions offered to the demands of a sector which is considered strategic for the country’s economy and which solution is essential to consolidate the recovery. It is because of this that the most important aspects of the reform have been analyzed through the making of an executive summary and it has also been studied the influence of the measures it includes from the point of view of three factors which have previously been considered as key for the Spanish port system recovery. The system has historically demanded a progressive tax flexibility, which would permit Spanish ports be more competitive compared to other port models much more flexible in rates, a necessary liberalization of the port service provision regime and last but not least, to cut the price of costs related to those services, mainly freight handling. Following this, the parliamentary process of the law has also been studied as a consequence of the vast consensus reached by the main political forces in the country which clearly determined that more than 700 amendments to the original project were presented. In some cases the focus has been on amendments which are adventurous and new, reason why they were finally not included to the final legal text. Being well aware of the importance that freight handling procedure has, I have made a specific reference to the legal and working framework of those employees related to this service. We conclude that the special working relationship, its different legal regime, along with the working relationship dualism has a big impact and decisive influence over the worker’s salary which also affects service users, mainly shipowners and terminal operators, having a bad effect on the port’s competitiveness. The above confirms the new opening trend of main European port laws with special attention to the frustrated European Union port services liberalization project, also known as Directive Loyola de Palacio (2003) and the White Paper on Transports (2011). It is important to highlight that the European Commission has also observed several deficiencies with regard to the freight handling port service Law Regime being in disagreement with it, considering it is against the free establishment rules in Europe. The Commission is likely to present a unilateral reform to the Spanish Port Law. Under this approach the service provision framework is being analyzed from the Port Community point of view. Initially the analysis will focus on the study of the competition forces within the port services industry in Spain, this will allow us to draw up an strategic map through “Porter’s Five Forces Model” concluding that the power of port services providers as freight handlers is maximum, with an only collective, stevedores, which has the exclusivity for their services. All these circumstances not only decrease the system’s competitiveness versus other more flexible but also restrain private investments. Secondly, through a participating procedure in different surveys about the legislative model and about the training framework with the affected agents within the port community, there is a triple perspective: Public point of view represented by Port Authorities as infrastructure managers, Private point of view represented by users and service suppliers as main Port’s customer and finally, port workforce, represented by union leaders. Results will let us conclude that freight handling service is the most critical port service and represents more than half of the costs. This service related workers aspire to obtain a training certificate that unifies and boosts their professional role which is also chased by the entire port community. Once conclusions have been analyzed for all research lines, several deficiencies have been found and the regulatory framework hasn’t yet been able to solve them, it has therefore been a series of necessary measures that help improve the port services provision regime. A new proposal to the Restated Law Text has been drafted as the first step to embrace a future legal reform. Conclusions obtained on the research should set the new basis of a deep reflection about the need to bent on a new legal reform which firmly bets on Spanish port system competitiveness from three key points of view, service liberalization, ship load cost reduction and professionalization of freight handling related workers.

Methodology for developing an advanced communications system for the Deaf in a new domain

A methodology for developing an advanced communications system for the Deaf in a new domain is presented in this paper. This methodology is a user-centred design approach consisting of four main steps: requirement analysis, parallel corpus generation, technology adaptation to the new domain, and finally, system evaluation. During the requirement analysis, both the user and technical requirements are evaluated and defined. For generating the parallel corpus, it is necessary to collect Spanish sentences in the new domain and translate them into LSE (Lengua de Signos Española: Spanish Sign Language). LSE is represented by glosses and using video recordings. This corpus is used for training the two main modules of the advanced communications system to the new domain: the spoken Spanish into the LSE translation module and the Spanish generation from the LSE module. The main aspects to be generated are the vocabularies for both languages (Spanish words and signs), and the knowledge for translating in both directions. Finally, the field evaluation is carried out with deaf people using the advanced communications system to interact with hearing people in several scenarios. In this evaluation, the paper proposes several objective and subjective measurements for evaluating the performance. In this paper, the new considered domain is about dialogues in a hotel reception. Using this methodology, the system was developed in several months, obtaining very good performance: good translation rates (10% Sign Error Rate) with small processing times, allowing face-to-face dialogues.

Approaching unbanked people: a person-to-person payment application on Facebook

More than 2.5 billion people are still unbanked and they do not access or use financial services. In this paper, we present an innovative service that allows Santander University Smart Card holders to make person-to-person payments to their friends, using different social channels, such as Telegram, Facebook or Twitter. Our first implementation is based on Facebook, one of the most used social networks. This approach allows the service to reach a great number of potential users but the delivery and stability of the service depends on an external provider. We include the description of the service architecture, its implementation, tests, and the lessons learned from the development. We also discuss pros and cons of the third party service dependency from the technical and business viewpoints.

GESTÃO DO CONHECIMENTO: UM ESTUDO SOBRE A RELAÇÃO ENTRE A LIDERANÇA TRANSFORMACIONAL, A CONVERSÃO DO CONHECIMENTO E A EFICÁCIA ORGANIZACIONAL

Este estudo teve como objetivo principal analisar a relação entre a Liderança Transformacional, a Conversão do Conhecimento e a Eficácia Organizacional. Foram considerados como pressupostos teóricos conceitos consolidados sobre os temas desta relação, além de recentes pesquisas já realizadas em outros países e contextos organizacionais. Com base nisto identificou-se potencial estudo de um modelo que relacionasse estes três conceitos. Para tal considera-se que as organizações que buscam atingir Vantagem Competitiva e incorporam a Knowledge-Based View possam conquistar diferenciação frente a seus concorrentes. Nesse contexto o conhecimento ganha maior destaque e papel protagonista nestas organizações. Dessa forma criar conhecimento através de seus colaboradores, passa a ser um dos desafios dessas organizações ao passo que sugere melhoria de seus indicadores Econômicos, Sociais, Sistêmicos e Políticos, o que se define por Eficácia Organizacional. Portanto os modos de conversão do conhecimento nas organizações, demonstram relevância, uma vez que se cria e se converte conhecimentos através da interação entre o conhecimento existente de seus colaboradores. Essa conversão do conhecimento ou modelo SECI possui quatro modos que são a Socialização, Externalização, Combinação e Internalização. Nessa perspectiva a liderança nas organizações apresenta-se como um elemento capaz de influenciar seus colaboradores, propiciando maior dinâmica ao modelo SECI de conversão do conhecimento. Se identifica então na liderança do tipo Transformacional, características que possam influenciar colaboradores e entende-se que esta relação entre a Liderança Transformacional e a Conversão do Conhecimento possa ter influência positiva nos indicadores da Eficácia Organizacional. Dessa forma esta pesquisa buscou analisar um modelo que explorasse essa relação entre a liderança do tipo Transformacional, a Conversão do Conhecimento (SECI) e a Eficácia Organizacional. Esta pesquisa teve o caráter quantitativo com coleta de dados através do método survey, obtendo um total de 230 respondentes válidos de diferentes organizações. O instrumento de coleta de dados foi composto por afirmativas relativas ao modelo de relação pesquisado com um total de 44 itens. O perfil de respondentes concentrou-se entre 30 e 39 anos de idade, com a predominância de organizações privadas e de departamentos de TI/Telecom, Docência e Recursos Humanos respectivamente. O tratamento dos dados foi através da Análise Fatorial Exploratória e Modelagem de Equações Estruturais via Partial Least Square Path Modeling (PLS-PM). Como resultado da análise desta pesquisa, as hipóteses puderam ser confirmadas, concluindo que a Liderança Transformacional apresenta influência positiva nos modos de Conversão do Conhecimento e que; a Conversão do Conhecimento influencia positivamente na Eficácia Organizacional. Ainda, concluiu-se que a percepção entre os respondentes não apresenta resultado diferente sobre o modelo desta pesquisa entre quem possui ou não função de liderança.

Detection of 400-year-old Yersinia pestis DNA in human dental pulp: An approach to the diagnosis of ancient septicemia

Ancient septicemic plague epidemics were reported to have killed millions of people for 2 millenniums. However, confident diagnosis of ancient septicemia solely on the basis of historical clinical observations is not possible. The lack of suitable infected material has prevented direct demonstration of ancient septicemia; thus, the history of most infections such as plague remains hypothetical. The durability of dental pulp, together with its natural sterility, makes it a suitable material on which to base such research. We hypothesized that it would be a lasting refuge for Yersinia pestis, the plague agent. DNA extracts were made from the dental pulp of 12 unerupted teeth extracted from skeletons excavated from 16th and 18th century French graves of persons thought to have died of plague (“plague teeth”) and from 7 ancient negative control teeth. PCRs incorporating ancient DNA extracts and primers specific for the human β-globin gene demonstrated the absence of inhibitors in these preparations. The incorporation of primers specific for Y. pestis rpoB (the RNA polymerase β-subunit-encoding gene) and the recognized virulence-associated pla (the plasminogen activator-encoding gene) repeatedly yielded products that had a nucleotide sequence indistinguishable from that of modern day isolates of the bacterium. The specific pla sequence was obtained from 6 of 12 plague skeleton teeth but 0 of 7 negative controls (P < 0.034, Fisher exact test). A nucleic acid-based confirmation of ancient plague was achieved for historically identified victims, and we have confirmed the presence of the disease at the end of 16th century in France. Dental pulp is an attractive target in the quest to determine the etiology of septicemic illnesses detected in ancient corpses. Molecular techniques could be applied to this material to resolve historical outbreaks.

Clinical Implications for Working with Gay Men A Self Psychological Treatment Approach.

Specific training for conducting psychotherapy with gay men is limited for psychologists, particularly when using a Self Psychology theoretical orientation (Robertson, 1996). In fact, psychologists often are faced with conflicting and contradictory points of view that mirror society's condemnation of homosexuality (Robertson, 1996). This paper is written from a self-psychological perspective to address the lack of a constructive body of literature that explains the unique treatment needs which impact gay men. Estimates of the prevalence of male homosexuality have generated considerable debate. A common assumption is that there are homosexual and non-homosexual men. However, scientists have long been aware that sexual responsiveness to others of the same sex, like most human traits, is continuously distributed in the population (Michaels, 1996). Still the presumption exists that such traits are stable within each man over time (Michaels, 1996). Conflating same-sex sexual experiences with a categorization of the man as homosexual is problematic, in that defining sexuality solely on the basis of experience excludes people who fantasize about sex with others of the same sex but never have sexual contact. Thus, most modern conceptions of sexual orientation consider personal identification, sexual behavior, and sexual fantasy (McWhirter, Sanders & Reinisch, 1990). Gay men's mental health can only be understood in the context of homosexuality throughout history, since religious and moral objections to sexual attraction between men have existed for centuries. Men who desired other men were regarded as sinful and depraved if not ill or abnormal, and same sex contacts were not distinguished from lewd behaviors (Weeks, 1989). Although most people, regardless of sexual orientation, have experienced some feelings of personal rejection, rarely do heterosexuals become targets for disapproval based on the nature of their attractions and behaviors relative to the same and to the other sex. For lesbians, bisexuals, and gay men, however, homosexuality becomes the focus of aspects of themselves that make them feel hated and hateful (Isay, 1989). While gay men and lesbians are often considered together because of the same-sex nature of their relationships and the similar issues that they may experience in their treatment within society, there are many issues where they might be best studied separately. Issues involving with health, parenthood, sexuality and perceived roles and status in society, for example, are often related more to gender than to any shared concept of a 'gay and lesbian community'. Many issues surrounding lesbians and lesbian culture will have more to do with women's issues, and some issues involving with gay men will have more to do with the gay male subculture and with masculinity. The author of this paper has limited experience in working with lesbian and bisexual individuals, and although it is likely that some of the concepts articulated in this paper could translate to working with lesbian and bisexual individuals, further research is indicated to examine the beneficence of utilizing a Self Psychological orientation in psychotherapy with lesbian women and bisexual individuals. This paper presents an overview of the literature including historical treatments of homosexuality, the history of Self Psychology, key principles in Self Psychology, research on Self Psychology, identity development models for gay men, and Self Psychological perspectives on identity development related to gay men. The literature review is followed by a section on treatment implications for psychologists seeking to treat gay men, including case vignettes based on work from my own practice. I have preserved the anonymity of clients by changing demographics, and rearranging and combining presenting issues and historical backgrounds among the case examples.

Dignity and the Eighth Amendment: A New Approach to Challenging Solitary Confinement

The use of solitary confinement in U.S. prisons and jails has come under increasing scrutiny. Over the past few months, Supreme Court Justice Anthony Kennedy all but invited constitutional challenges to the use of solitary confinement, while President Obama asked, “Do we really think it makes sense to lock so many people alone in tiny cells for 23 hours a day for months, sometime for years at a time?” Even some of the most notorious prisons and jails, including California’s Pelican Bay State Prison and New York’s Rikers Island, are reforming their use of solitary confinement because of successful litigation and public outcry. Rovner suggests that in light of these developments and “the Supreme Court’s increasing reliance on human dignity as a substantive value underlying and animating constitutional rights,” there is a strong case to make that long-term solitary confinement violates the constitutional right to freedom from cruel and unusual punishment.

A relaxation technique enhances psychological well-being and immune parameters in elderly people from a nursing home: A randomized controlled study

Background: The aging process involves a decline in immune functioning that renders elderly people more vulnerable to disease. In residential programs for the aged, it is vital to diminish their risk of disease, promote their independence, and augment their psychological well-being and quality of life. Methods: We performed a randomized controlled study, evaluating the ability of a relaxation technique based on Benson’s relaxation response to enhance psychological well-being and modulate the immune parameters of elderly people living in a geriatric residence when compared to a waitlist control group. The study included a 2-week intervention period and a 3-month follow-up period. The main outcome variables were psychological well-being and quality of life, biomedical variables, immune changes from the pre-treatment to post-treatment and follow-up periods. Results: Our findings reveal significant differences between the experimental and control groups in CD19, CD71, CD97, CD134, and CD137 lymphocyte subpopulations at the end of treatment. Furthermore, there was a decrease in negative affect, psychological discomfort, and symptom perception in the treatment group, which increased participants’ quality of life scores at the three-month follow-up. Conclusions: This study represents a first approach to the application of a passive relaxation technique in residential programs for the elderly. The method appears to be effective in enhancing psychological well-being and modulating immune activity in a group of elderly people. This relaxation technique could be considered an option for achieving health benefits with a low cost for residential programs, but further studies using this technique in larger samples of older people are needed to confirm the trends observed in the present study.

Applying the WHO recommendations on health-sector response to violence against women to assess the Spanish health system. A mixed methods approach

This methodological note describes the development and application of a mixed-methods protocol to assess the responsiveness of Spanish health systems to violence against women in Spain, based on the World Health Organization (WHO) recommendations. Five areas for exploration were identified based on the WHO recommendations: policy environment, protocols, training, accountability/monitoring, and prevention/promotion. Two data collection instruments were developed to assess the situation of 17 Spanish regional health systems (RHS) with respect to these areas: 1) a set of indicators to guide a systematic review of secondary sources, and 2) an interview guide to be used with 26 key informants at the regional and national levels. We found differences between RHSs in the five areas assessed. The progress of RHSs on the WHO recommendations was notable at the level of policies, moderate in terms of health service delivery, and very limited in terms of preventive actions. Using a mixed-methods approach was useful for triangulation and complementarity during instrument design, data collection and interpretation.

Using realist evaluation to assess primary healthcare teams’ responses to intimate partner violence in Spain

Objective: Few evaluations have assessed the factors triggering an adequate health care response to intimate partner violence. This article aimed to: 1) describe a realist evaluation carried out in Spain to ascertain why, how and under what circumstances primary health care teams respond to intimate partner violence, and 2) discuss the strengths and challenges of its application. Methods: We carried out a series of case studies in four steps. First, we developed an initial programme theory (PT1), based on interviews with managers. Second, we refined PT1 into PT2 by testing it in a primary healthcare team that was actively responding to violence. Third, we tested the refined PT2 by incorporating three other cases located in the same region. Qualitative and quantitative data were collected and thick descriptions were produced and analysed using a retroduction approach. Fourth, we analysed a total of 15 cases, and identified combinations of contextual factors and mechanisms that triggered an adequate response to violence by using qualitative comparative analysis. Results: There were several key mechanisms —the teams’ self-efficacy, perceived preparation, women-centred care—, and contextual factors —an enabling team environment and managerial style, the presence of motivated professionals, the use of the protocol and accumulated experience in primary health care—that should be considered to develop adequate primary health-care responses to violence. Conclusion: The full application of this realist evaluation was demanding, but also well suited to explore a complex intervention reflecting the situation in natural settings.
