[Psychosomatic medicine and arterial hypertension - love it or leave it?]

Over the last two decades modern psychosomatic research has found multiple evidence for an impact of psychosocial factors on the control of arterial blood pressure as well as the development of arterial hypertension. This narrative review focuses first on the current stress concept and factors that influence the degree of blood pressure change following a psychosocial stressor. Second, relevant psychosocial factors associated with blood pressure are presented such as marital status, social support, socioeconomic status and work conditions. In addition, the influence of personality and cognition on blood pressure will be discussed. The second part focuses on the outcome of cognitive-behavioral therapies and relaxation techniques as a means to effectively control blood pressure. In conclusion, there is now good evidence showing that psychosocial factors and stressors may increase blood pressure. The working environment, the socioeconomic status as well as aspects of personality and cognitive factors like rumination may also impact blood pressure with to an extent that is clinically relevant. With respect to therapeutic options, cognitive-behavioral interventions, combined with relaxation techniques all fitting the needs of the individual patient best can offer a clinically meaningful contribution of an effective blood pressure control.

The Permanent Income Hypothesis: A Test on Czech Privatisation

Since the late eighties, economists have been regarding the transition from command to market economies in Central and Eastern Europe with intense interest. In addition to studying the transition per se, they have begun using the region as a testing ground on which to investigate the validity of certain classic economic propositions. In his research, comprising three articles written in English and totalling 40 pages, Mr. Hanousek uses the so-called "Czech national experiment" (voucher privatisation scheme) to test the permanent income hypothesis (PIH). He took as his inspiration Kreinin's recommendation: "Since data concerning the behaviour of windfall income recipients is relatively scanty, and since such data can constitute an important test of the permanent income hypothesis, it is of interest to bring to bear on the hypothesis whatever information is available". Mr. Hanousek argues that, since the transfer of property to Czech citizens from 1992 to 1994 through the voucher scheme was not anticipated, it can be regarded as windfall income. The average size of the windfall was more than three month's salary and over 60 percent of the Czech population received this unexpected income. Furthermore, there are other reasons for conducting such an analysis in the Czech Republic. Firstly, the privatisation process took place quickly. Secondly, both the economy and consumer behaviour have been very stable. Thirdly, out of a total population of 10 million Czech citizens, an astonishing 6 million, that is, virtually every household, participated in the scheme. Thus Czech voucher privatisation provides a sample for testing the PIH almost equivalent to a full population, thus avoiding problems with the distribution of windfalls. Compare this, for instance with the fact that only 4% of the Israeli urban population received personal restitution from Germany, while the number of veterans who received the National Service Life Insurance Dividends amounted to less than 9% of the US population and were concentrated in certain age groups. But to begin with, Mr. Hanousek considers the question of whether the public percieves the transfer from the state to individual as an increase in net wealth. It can be argued that the state is only divesting itself of assets that would otherwise provide a future source of transfers. According to this argument, assigning these assets to individuals creates an offsetting change in the present value of potential future transfers so that individuals are no better off after the transfer. Mr. Hanousek disagrees with this approach. He points out that a change in the ownership of inefficient state-owned enterprises should lead to higher efficiency, which alone increases the value of enterprises and creates a windfall increase in citizens' portfolios. More importantly, the state and individuals had very different preferences during the transition. Despite government propaganda, it is doubtful that citizens of former communist countries viewed government-owned enterprises as being operated in the citizens' best interest. Moreover, it is unlikely that the public fully comprehended the sophisticated links between the state budget, state-owned enterprises, and transfers to individuals. Finally, the transfers were not equal across the population. Mr. Hanousek conducted a survey on 1263 individuals, dividing them into four monthly earnings categories. After determining whether the respondent had participated in the voucher process, he asked those who had how much of what they received from voucher privatisation had been (a) spent on goods and services, (b) invested elsewhere, (c) transferred to newly emerging pension funds, (d) given to a family member, and (e) retained in their original form as an investment. Both the mean and the variance of the windfall rise with income. He obtained similar results with respect to education, where the mean (median) windfall for those with a basic school education was 13,600 Czech Crowns (CZK), a figure that increased to 15,000 CZK for those with a high school education without exams, 19,900 CZK for high school graduates with exams, and 24,600 CZK for university graduates. Mr. Hanousek concludes that it can be argued that higher income (and better educated) groups allocated their vouchers or timed the disposition of their shares better. He turns next to an analysis of how respondents reported using their windfalls. The key result is that only a relatively small number of individuals reported spending on goods. Overall, the results provide strong support for the permanent income hypothesis, the only apparent deviation being the fact that both men and women aged 26 to 35 apparently consume more than they should if the windfall were annuitised. This finding is still fully consistent with the PIH, however, if this group is at a stage in their life-cycle where, without the windfall, they would be borrowing to finance consumption associated with family formation etc. Indeed, the PIH predicts that individuals who would otherwise borrow to finance consumption would consume the windfall up to the level equal to the annuitised fraction of the increase in lifetime income plus the full amount of the previously planned borrowing for consumption. Greater consumption would then be financed, not from investing the windfall, but from avoidance of future repayment obligations for debts that would have been incurred without the windfall.

Say on Pay: ein Überblick über Gestaltungsoptionen, ökonomische Konsequenzen und Erkenntnisse aus Empirie und Laborexperimenten

Unter dem Stichwort Say on Pay (SoP) haben in den letzen Jahren die meisten Länder der EU und die USA den Aktionären Abstimmungsrechte im Zusammenhang mit der Vergütung des Top-Managements eingeräumt. Zwischen den einzelnen Ländern bestehen jedoch erhebliche Unterschiede hinsichtlich der konkreten Ausgestaltung des SoP. Dieser Beitrag diskutiert die Wirkungen unterschiedlicher Gestaltungsoptionen des SoP auf die Anreizgestaltung und den Nutzen des Managements und der Aktionäre im Rahmen eines einfachen linearen Agency Modells. Dabei erweisen sich das vorvertragliche bindende SoP und das bedingt verpflichtende, nachvertragliche bindende SoP gegenüber den anderen untersuchten Varianten als überlegen. Während das konsultative SoP an seiner mangelnden Durchsetzbarkeit leidet, bietet das nachvertragliche bindende SoP Anreize für opportunistisches Verhalten auf Seiten der Aktionäre und führt deshalb zu Wohlfahrtsverlusten. In Ergänzung der Modellanalyse wird ein Überblick über die wichtigsten empirischen und experimentellen Studien zum Thema SoP gegeben und deren Inhalt im Lichte der Modellergebnisse diskutiert. Most countries of the European Union as well as the US recently introduced shareholder votes on the remuneration of executives, also referred to as “Say on Pay” (SoP). Interestingly, legislators in different jurisdictions opted for quite dissimilar voting right regimes. We provide an overview of the main regulatory approaches and discuss the potential impact of variations in SoP design on the structure of compensation contracts and the utility of shareholders and executives. We find that pre-contractual SoP and conditional post-contractual SoP with binding consequences are in the best interest of shareholders. By contrast, advisory SoP typically suffers from lacking enforceability. We also find that post-contractual SoP with binding consequences results in efficiency losses because it fuels moral hazard on the part of shareholders. We complement the theoretical analysis with a discussion of recent empirical and experimental studies on Say on Pay.

The Need for School-Based Teen Dating Violence Prevention

Schools have several competing demands, and often suffer from inefficient access to needed resources. Thus, the addition of any program into an already overtaxed school system must be met with convincing evidence that 1) a need or problem exists and is relevant to the education of students, 2) the problem is amenable to change, and 3) addressing the problem is in the best interest of educators and students. The purpose of the present paper is to present a case for inclusion of teen dating violence prevention programs in middle and high schools. We also discuss a recent survey of 219 employees of a suburban school district in southeast Texas. Specifically, we examined their perceived need for and appropriateness of a school-based dating violence prevention program. The anonymous internet-based survey revealed that a majority of participants believed that teen dating violence was a problem, 19% reported having observed an instance of teen dating violence, and 82% believed school to be an appropriate outlet for the implementation of a dating violence prevention program.

Is the anti-trafficking framework really for the 'victims'? : reflections on Burmese victims of human trafficking and non-trafficked migrants in Thailand

Since the year 2000 when the Protocol to Prevent, Suppress and Punish Trafficking in Persons, Especially Women and Children, human trafficking has been regarded as one of the egregious violations of human rights, and global efforts have been made to eradicate it. The anti-trafficking framework has multiple dimensions, and the way the anti-trafficking framework is constructed influences its impact on the victims and non-trafficked migrants. This paper will analyze the impact of the anti-trafficking framework on the experiences of Burmese victims and non-trafficked migrants in Thailand. I will question the conventional framework of anti-trafficking, and seek to construct a framework more appropriate for addressing victims' actual needs. In conclusion, the anti-trafficking framework should serve the best interest of the victim; still, it should not be one which might adversely affect the interest of the would-be victim who is not identified as a victim according to the law.

Intereses exógenos y resistencia ciudadana en la transformación físicosocial de un asentamiento auto-producido de Dakar (2005-2011)

La presión sobre el acceso a la tierra en la península de Dakar, Senegal, ha generado un proceso de transformación físico-social del mayor asentamiento auto-producido de la periferia urbana de Dakar (Pikine Irregular Sur) en el periodo 2005-2011. Esta investigación se propone analizar en qué medida las acciones llevadas a cabo: i) satisfacen o no el sistema integral de necesidades de los afectados (Demanda); ii) favorecen la implicación de los afectados o, por el contrario, fortalecen las estructuras de poder dominantes (Oferta), y iii) promueven o no la autonomía económica, la sostenibilidad ambiental, la equidad social y la legitimidad de los actores que participan (Entorno). La investigación se ha llevado a cabo por el método de estudio de casos, mediante un proceso de recogida de información participativo, articulado de abajo hacia arriba, en el que han participado 196 personas; la información recogida se ha procesado mediante la utilización de dos herramientas de análisis de realidades complejas: flujo de programa y sistema funcional. Los resultados del estudio de los casos 1 y 2 muestran que las acciones se han llevado a cabo en beneficio de los intereses de los mercados y de los actores que toman las decisiones y gestionan los recursos, incrementando la dependencia económica, empobreciendo a los directamente afectados y fragmentando su tejido social, promoviendo un desarrollo urbano desequilibrado, disperso y segregado, y deslegitimando a las instituciones involucradas. En el estudio del caso 3, en cambio, se verifica que la acción se ha llevado a cabo en beneficio de los intereses de los directamente afectados, utilizando recursos endógenos, fortaleciendo su tejido social, promoviendo un desarrollo urbano concentrado e inclusivo, e incrementando la legitimidad de las instituciones involucradas. El análisis cruzado de los resultados muestra que la pobreza, la exclusión social y la precariedad habitacional, en el contexto específico de la periferia de Dakar, no son un problema de falta de recursos, sino de falta de ética por parte de quienes gestionan y financian los procesos de transformación físico-social, y de falta de voluntad por parte de las autoridades de implicar a los ciudadanos, y en particular a los directamente afectados, en los procesos de toma de decisiones de las acciones y los programas que les afectan. Finalmente se concluye que no se trata de luchar contra la pobreza, sino de luchar contra los sistemas injustos que generan la pobreza y la exclusión. ABSTRACT The pressure on the access to land in the area of Dakar, Senegal, has generated a physical/social transformation process in the largest self-produced settlement in the urban periphery of Dakar (South Irregular Pikine), in the period 2005-2011. This research aims to analyze to what extent the actions carried out: i) satisfy the integral needs of the affected population (Demand), ii) encourage the involvement of those affected or otherwise strengthen dominant power structures (Supply), and iii) promote or inhibit economic autonomy, environmental sustainability, social equity and legitimacy of the actors involved (Environment). The research was conducted by the case study method. 196 people participated in a bottom-up participatory process of information gathering. The information collected was processed using two custom tools aimed to analyse complex systems: the program flow and the functional system. The results of case studies 1 and 2 show that the actions were carried out in the best interest of the markets and the actors who made decisions and managed resources, increasing economic dependence, impoverishing those directly affected and fragmenting their social network by promoting an unbalanced, dispersed and segregated urban development, and de-legitimizing the institutions involved in the process. On the contrary, in the case study 3 it is verified that the action has been carried out on behalf of the interests of those directly affected, using endogenous resources, strengthening the social network, promoting a focused and inclusive urban development, and increasing legitimacy of the institutions involved. The comparative analysis of the results shows that poverty, social exclusion and precarious housing in South Irregular Pikine are not a problem of lack of resources but of unethical behaviour of those who manage and finance physical and social transformation processes, as well as unwillingness on the part of the authorities to involve citizens in the decision making processes for the actions and programs that affect them. Finally we conclude that the enemy to fight against is not poverty but unfair systems that generate poverty and exclusion. RÉSUMÉ La pression sur le foncier dans la presqu'île de Dakar, au Sénégal, a généré un processus de transformation physico-sociale du plus grand établissement auto-produit de la périphérie urbaine de Dakar (Pikine Irrégulier Sud), durant la période 2005-2011. Cette recherche vise à analyser dans quelle mesure les actions menées: i) répondent ou non à l’ensemble des besoins intégrales des personnes concernés (Demande), ii) encouragent l'implication des concernées ou au contraire renforcent les structures de pouvoir dominant (Offre), et iii) favorisent ou non l'autonomie économique, la durabilité environnementale, l'équité sociale et la légitimité des acteurs concernés (Contexte). La recherche a été menée par la méthode des études de cas, par un processus de collecte d'information participative articulée du bas vers le haut dans lequel ont participé 196 personnes. Les informations recueillies ont été traitées à l'aide de deux outils d'analyse de réalités complexes: le système fonctionnel et le flux de programme. Les résultats de l'étude de cas 1 et 2 montrent que les actions ont été menées au profit des intérêts des marchés et des acteurs qui prennent les décisions et gèrent les ressources, augmentant la dépendance économique, appauvrissant ceux qui sont directement concernés et fragmentant leur tissu social, encourageant un développement urbain déséquilibré, dispersé et ségrégé, et délégitimant les institutions concernées. Dans l'étude de cas 3, cependant, il est vérifié que l'action a été menée au profit des intérêts de ceux qui sont directement concernés, en utilisant des ressources endogènes, en renforçant son tissu social, en encourageant un développement urbain concentré et inclusif, et en augmentant la légitimité des institutions concernées. L'analyse comparée des résultats montre que la pauvreté, l'exclusion sociale et le logement précaire, dans le contexte spécifique de la banlieue de Dakar, ne sont pas un problème de manque de ressources, mais de manque d'éthique de la part de ceux qui gèrent et financent les processus de transformation physico-sociale, et de manque de volonté de la part des autorités d'impliquer les citoyens, en particulier ceux qui sont directement concernés, dans le processus de prise de décision des actions et des programmes qui les impliquent. Finalement, on conclut qu'il ne s'agit pas de lutter contre la pauvreté, mais de lutter contre les systèmes injustes qui produisent la pauvreté et l'exclusion.

Optimal water allocation in shortage situations as applied to an irrigation community.

This work studies the most beneficial way of allocating water in an irrigation community in water shortage situations. Therefore, it proposes that the irrigation surface area be divided into homogeneous zones, each with a beneficial relationship with respect to the water applied. The mathematical formula that enables one to obtain the optimal quota for the users or irrigation community as a whole has been found for individual relations of a quadratic or power type, and these have yielded different and complementary characteristics. Dimensionless variables have been used to display the results, and to compare with other alternative allocation rules such as the proportional rule, referencing the situation without water restrictions. As a result, for each water shortage situation, the water that is allocated to each user is obtained, together with the losses in individual income and the losses for the community as a whole. Furthermore, a proposal is put forth for establishing the marginal benefit from the water available, which could be of interest in enabling each community to analyze whether it is in its best interest to invest in increasing the resource, or to sell the resource to other users. Finally, an example is given to demonstrate how the method works and to show that, when the differences between the production schemes are considered, the differences in benefit reduction between the proportional allocation and the optimal allocation are also sizeable.

Étude exploratoire sur le point de vue des enfants placés vivant l'expérience d'avoir des visites supervisées avec leurs parents

L’objectif de ce mémoire est de mieux comprendre, à partir de leur point de vue, le vécu des enfants âgés de 6 à 12 ans qui sont placés dans des ressources d’accueil et qui vivent l’expérience d’avoir des visites supervisées avec leurs parents. Pour ce faire, des entrevues semi-dirigées ont été réalisées auprès de douze enfants hébergés dans des unités de vie, foyers de groupe ou ressources intermédiaires du Centre jeunesse de Montréal – Institut Universitaire et du Centre jeunesse de la Montérégie. Les entrevues réalisées auprès des enfants ont été soumises à une analyse de contenu thématique. Les résultats de l’étude montrent que les enfants ne comprennent pas toujours bien les raisons qui justifient la mise en place de visites supervisées, ni le rôle des adultes dans les décisions, ni celui du tiers durant les visites. De façon générale, les enfants sont favorables au maintien des contacts avec leurs parents, mais sont plus critiques face aux cadres imposés par ces visites. Il ressort également de l’étude que les enfants sont très peu consultés en lien avec l’organisation et la planification de leurs visites et qu’ils souhaiteraient l’être davantage. Les enfants ont rapporté de nombreuses insatisfactions en lien avec les modalités organisationnelles des visites. L’analyse du discours qui a été menée a permis de mettre en évidence le fait que les visites supervisées sont une source de stress importante pour l’enfant. La création d’un guide d’information destiné aux enfants pour expliquer ce qu’est une visite supervisée, les raisons de sa mise en place, ses buts et ses objectifs serait une piste intéressante à explorer.

An analysis of the factors that influence regional economic development cooperation

This dissertation is a comparative case study of regional cooperation in the field of economic development. In the 21st century global economy, proponents of regionalism have put forth fresh arguments for collective action. A regional approach to economic development activity presents a classic social dilemma: How can local officials collectively improve the economic prospects of a region, and remain autonomous to act in the best interest of the local community? This research examines the role of social capital in overcoming this social dilemma. ^ Three (3) comparable Metropolitan Statistical Areas (MSAs) form the empirical basis of this research. The Houston MSA, the Atlanta MSA and the Miami MSA present distinct variations of regionalized economic development activity. This dissertation seeks to explain this disparity in the dependent variable. The hypothesis is that accrued social capital is crucial to obtaining economic development cooperative agreements.^ This qualitative research utilized secondary demographic and economic databases, survey instruments, interviews, field observations, and a review of legislative and administrative decisions to formulate a clear understanding of the factors influencing the current state of regional economic development cooperation within each region. The study concludes that the legislative and executive decisions of state government exert inordinate influence on the capacity of local officials to cooperate regionally for economic development purposes.^

A study of the relationship between employee virtuality and technology deviance as mediated by leadership and employee perceptions

Recent studies found that organizations have been investing significant capital in developing teams and employees in geographic areas where labor and resources are considerably cheaper. Furthermore, organizations are moving core operational activities such as research and development and back-office processes to globally distributed teams. ^ However, several factors that are inherent to these virtual teams can have a negative impact on employee perceptions and engagement; specifically, the physical and temporal differences between employees and their supervisors, the lack of meaningful social interaction intrinsic to working relationships, and cultural biases that can be fostered when close, daily interactions is not there to help bridge the dissimilarity. ^ When strategies are not in place to mitigate these deficiencies, it can cause virtual employees to disengage emotionally and intellectually from the organization, or lead them to feel justified in working against the best interest of the company. ^ Past research indicates that although deviant behavior in the workplace is not new, transgressions committed by employees have been increasing significantly every year. Beyond the focus of why employees are motivated to act against the organization, to what extent do the recent changes to the organization’s structure influence this type of behavior through their actions at the macro (organizational) and micro level (leadership). ^ In addition, there is a related phenomenon that has aided the transformation of the workplace—namely, the ubiquity of technology. In the context of workplace deviance, established research has documented an increasing trend of employees utilizing company technology as a medium and amplifier when harming the organization. It is important to understand whether technology has facilitated or hindered workplace deviance by virtue of the technology itself (as a means), and as part of the new employee roles created by the evolving technology (i.e., virtual employees). Therefore, it is important to identify how individual attitudes and behaviors can be affected by an employee’s degree of virtuality. ^ This study will add to the understanding of how social interaction and physical proximity, leadership and other perception factors contribute to the changes organizations are experiencing as their structure evolves and adapts to compete in the new global environment. ^

Lärares ledarskap som möjliggörande och begränsande i mötet med ’alla’ barn : En deltagarorienterad studie

The aim of this thesis is to, based on teachers’ experiences, describe and analyse meanings of teachers’ leadership in general, and in relation to children in need of special support in particular. The study was carried out within the tradition of participatory-oriented research, a research circle. The dialogues in the circle were based on the participants’ questions, experiences, interests, and knowledge. The circle included a researcher and nine teachers from the following types of schools: preschool, preschool class, compulsory school, and compulsory school for pupils with learning disabilities. The study is based on an understanding of leadership as a relational practice. Leadership is practised in the interaction between teacher and child. Both parties exert influence over the practice of leadership. A central assumption in the study is that knowledge can develop through and in interactions between people, that knowledge and power are connected, and that knowledge and actions are intertwined. Another central assumption is that learning is a complex phenomenon. In the analysis of the research circle’s dialogues, the following meanings of teachers’ leadership emerge: to facilitate learning and discipline, and to promote different interests. The practice of leadership involves teachers handling complex situations in their interactions with ‘all’ children, i.e. children in need of special support and children without such needs. Leadership is practised between teachers and children, and the teachers have to consider the group of children as a collective in relation to the individual children. At the same time, the teachers have to consider their intentions versus what happens during the interactions. In addition, the teachers have to pay heed to the fact that their own actions and the children’s actions influence one another. Finally, the teachers have to consider the individual child’s ‘best interest’ in relation to the requirements of the policy documents. Furthermore, the results indicate that the practice of leadership is perceived as both unpredictable and, to some extent, predictable at the same time, which adds to the complexity of leadership. The teachers cannot know for sure what the children understand or if the children’s actions facilitate learning. However, the teachers can make certain assumptions about how to practice leadership in order to facilitate learning and discipline in children with different needs. The meanings of leadership were expressed in different ways in the circle’s dialogues; both as enabling and limiting in interactions with children in need of special support. One of the study’s conclusions is that leadership seems to be particularly complex in interactions with children in need of special support. The research circle’s dialogues served to promote a democratic knowledge process. The dialogues were characterised by respect for the participants’ different opinions; however, this does not mean that they were free from power structures.

Development of an Economic Dust Palliative for Limestone Surfaced Secondary Roads, HR-297, Progress Report, 1988

Research activities during this period concentrated on continuation of field and laboratory testing for the Dallas County test road. Stationary ditch collection of dust was eliminated because of inconsistent data, and because of vandalism to collectors. Braking tests were developed and initiated to evaluate the influence of treatments on braking and safety characteristics of the test sections. Dust testing was initiated for out of the wheelpath conditions as well as in the wheelpath. Contrary to the results obtained during the summer and fall of 1987, the 1.5 percent bentonite treatment appears to be outperforming the other bentonite treated sections after over a year of service. Overall dust reduction appears to average between 25 to 35 percent. Dallas County applied 300 tons per mile of class A roadstone maintenance surfacing to the test road in August 1988. Test data indicates that the bentonite is capable of interacting and functioning to reduce dust generation of the new surfacing material. Again, the 1.5 percent bentonite treatment appeared the most effective. The fine particulate bonding and aggregation mechanism of the bentonite appears recoverable from the environmental effects of winter, and from alternating wet and dry road surface conditions. The magnesium chloride treatment appears capable of long-term (over one year) dust reduction and exhibited an overall average reduction in the range of 15 to 30 percent. The magnesium chloride treatment also appears capable of interacting with newly applied crushed stone to reduce dust generation. Two additional one mile test roads were to have been constructed early this year. Due to an extremely dry spring and summer, construction scheduling was not possible until August. This would have allowed only minimal data collection. Considering this and the fact that this was an atypically dry summer, it was our opinion that it would be in the best interest of the research project to extend the project (at no additional cost) for a period of one year. The two additional test roads will be constructed in early spring 1989 in Adair and Marion counties.
