How expectations affect reference point formation: an experimental investigation

This paper addresses two major topics concerning the role of expectations in the formation of reference points. First, we show that when expectations are present, they have a significant impact on reference point formation. Second, we find that decision-makers employ expected values when forming reference points (integrated mechanism) as opposed to single possible outcomes (segregated mechanism). Despite the importance of reference points in prospect theory, to date, there is no standard method of examining these. We develop a new experimental design that employs an indirect approach and extends an existing direct approach. Our findings are consistent across the two approaches.

Variable phenotypic expressivity in inbred retinal degeneration mouse lines: A comparative study of C3H/HeOu and FVB/N rd1 mice

PURPOSE Recent advances in optogenetics and gene therapy have led to promising new treatment strategies for blindness caused by retinal photoreceptor loss. Preclinical studies often rely on the retinal degeneration 1 (rd1 or Pde6b(rd1)) retinitis pigmentosa (RP) mouse model. The rd1 founder mutation is present in more than 100 actively used mouse lines. Since secondary genetic traits are well-known to modify the phenotypic progression of photoreceptor degeneration in animal models and human patients with RP, negligence of the genetic background in the rd1 mouse model is unwarranted. Moreover, the success of various potential therapies, including optogenetic gene therapy and prosthetic implants, depends on the progress of retinal degeneration, which might differ between rd1 mice. To examine the prospect of phenotypic expressivity in the rd1 mouse model, we compared the progress of retinal degeneration in two common rd1 lines, C3H/HeOu and FVB/N. METHODS We followed retinal degeneration over 24 weeks in FVB/N, C3H/HeOu, and congenic Pde6b(+) seeing mouse lines, using a range of experimental techniques including extracellular recordings from retinal ganglion cells, PCR quantification of cone opsin and Pde6b transcripts, in vivo flash electroretinogram (ERG), and behavioral optokinetic reflex (OKR) recordings. RESULTS We demonstrated a substantial difference in the speed of retinal degeneration and accompanying loss of visual function between the two rd1 lines. Photoreceptor degeneration and loss of vision were faster with an earlier onset in the FVB/N mice compared to C3H/HeOu mice, whereas the performance of the Pde6b(+) mice did not differ significantly in any of the tests. By postnatal week 4, the FVB/N mice expressed significantly less cone opsin and Pde6b mRNA and had neither ERG nor OKR responses. At 12 weeks of age, the retinal ganglion cells of the FVB/N mice had lost all light responses. In contrast, 4-week-old C3H/HeOu mice still had ERG and OKR responses, and we still recorded light responses from C3H/HeOu retinal ganglion cells until the age of 24 weeks. These results show that genetic background plays an important role in the rd1 mouse pathology. CONCLUSIONS Analogous to human RP, the mouse genetic background strongly influences the rd1 phenotype. Thus, different rd1 mouse lines may follow different timelines of retinal degeneration, making exact knowledge of genetic background imperative in all studies that use rd1 models.

Causes, forms and consequences of the professionalization of international sport federa-tions in Switzerland: Conceptual framework and first results

Synopsis: Sport organisations are facing multiple challenges originating from an increasingly complex and dynamic environment in general, and from internal changes in particular. Our study seeks to reveal and analyse the causes for professionalization processes in international sport federations, the forms resulting from it, as well as related consequences. Abstract: AIM OF ABSTRACT/PAPER - RESEARCH QUESTION Sport organisations are facing multiple challenges originating from an increasingly complex and dynamic environment in general, and from internal changes in particular. In this context, professionalization seems to have been adopted by sport organisations as an appropriate strategy to respond to pressures such as becoming more “business-like”. The ongoing study seeks to reveal and analyse the internal and external causes for professionalization processes in international sport federations, the forms resulting from it (e.g. organisational, managerial, economic) as well as related consequences on objectives, values, governance methods, performance management or again rationalisation. THEORETICAL BACKGROUND/LITERATURE REVIEW Studies on sport as specific non-profit sector mainly focus on the prospect of the “professionalization of individuals” (Thibault, Slack & Hinings, 1991), often within sport clubs (Thiel, Meier & Cachay, 2006) and national sport federations (Seippel, 2002) or on organisational change (Griginov & Sandanski, 2008; Slack & Hinings, 1987, 1992; Slack, 1985, 2001), thus leaving broader analysis on governance, management and professionalization in sport organisations an unaccomplished task. In order to further current research on above-mentioned topics, our intention is to analyse causes, forms and consequences of professionalisation processes in international sport federations. The social theory of action (Coleman, 1986; Esser, 1993) has been defined as appropriate theoretical framework, deriving in the following a multi-level framework for the analysis of sport organisations (Nagel, 2007). In light of the multi-level framework, sport federations are conceptualised as corporative actors whose objectives are defined and implemented with regard to the interests of member organisations (Heinemann, 2004) and/or other pressure groups. In order to understand social acting and social structures (Giddens 1984) of sport federations, two levels are in the focus of our analysis: the macro level examining the environment at large (political, social, economic systems etc.) and the meso level (Esser, 1999) examining organisational structures, actions and decisions of the federation’s headquarter as well as member organisations. METHODOLOGY, RESEARCH DESIGN AND DATA ANALYSIS The multi-level framework mentioned seeks to gather and analyse information on causes, forms and consequences of professionalization processes in sport federations. It is applied in a twofold approach: first an exploratory study based on nine semi-structured interviews with experts from umbrella sport organisations (IOC, WADA, ASOIF, AIOWF, etc.) as well as the analysis of related documents, relevant reports (IOC report 2000 on governance reform, Agenda 2020, etc.) and important moments of change in the Olympic Movement (Olympic revenue share, IOC evaluation criteria, etc.); and secondly several case studies. Whereas the exploratory study seeks more the causes for professionalization on an external, internal and headquarter level as depicted in the literature, the case studies rather focus on forms and consequences. Applying our conceptual framework, the analysis of forms is built around three dimensions: 1) Individuals (persons and positions), 2) Processes, structures (formalisation, specialisation), 3) Activities (strategic planning). With regard to consequences, we centre our attention on expectations of and relationships with stakeholders (e.g. cooperation with business partners), structure, culture and processes (e.g. governance models, performance), and expectations of and relationships with member organisations (e.g. centralisation vs. regionalisation). For the case studies, a mixed-method approach is applied to collect relevant data: questionnaires for rather quantitative data, interviews for rather qualitative data, as well as document and observatory analysis. RESULTS, DISCUSSION AND IMPLICATIONS/CONCLUSIONS With regard to causes of professionalization processes, we analyse the content of three different levels: 1. the external level, where the main pressure derives from financial resources (stakeholders, benefactors) and important turning points (scandals, media pressure, IOC requirements for Olympic sports); 2. the internal level, where pressure from member organisations turned out to be less decisive than assumed (little involvement of member organisations in decision-making); 3. the headquarter level, where specific economic models (World Cups, other international circuits, World Championships), and organisational structures (decision-making procedures, values, leadership) trigger or hinder a federation’s professionalization process. Based on our first analysis, an outline for an economic model is suggested, distinguishing four categories of IFs: “money-generating IFs” being rather based on commercialisation and strategic alliances; “classical Olympic IFs” being rather reactive and dependent on Olympic revenue; “classical non-Olympic IFs” being rather independent of the Olympic Movement; and “money-receiving IFs” being dependent on benefactors and having strong traditions and values. The results regarding forms and consequences will be outlined in the presentation. The first results from the two pilot studies will allow us to refine our conceptual framework for subsequent case studies, thus extending our data collection and developing fundamental conclusions.

Theory after Dialogue: Christian-Muslim Engagement Today and Tomorrow

The phenomenon of Christian–Muslim dialogue has had a very chequered history. At varying times, three broad modes of engagement can be said to have operated: antipathy, affinity and inquiry, and these three modes can be found still in today's world. In some places, hostility and antipathy abound. In others, voices and actions express cordial friendship, détente and affinity. In this latter climate, the prospect of engagement in mutual inquiry and cooperative ventures is not only theoretically possible, but actively pursued, and in the first decade of the twenty-first century, a number of notable initiatives in the arena of mutual inquiry have taken place. This article addresses aspects of the context and development of Christian–Muslim dialogue as a modern phenomenon, and then turns to a review of three twenty-first century developments – the Building Bridges seminar series; the Stuttgart-based Christian–Muslim Theological Forum and the “Common Word” letter. It also reflects on the models and theology of dialogue, including not only theology for dialogue, but also theology in and – importantly – after dialogue.

A model of factors determining levels of public support for health care policy in the United States

Public preferences for policy are formed in a little-understood process that is not adequately described by traditional economic theory of choice. In this paper I suggest that U.S. aggregate support for health reform can be modeled as tradeoffs among a small number of behavioral values and the stage of policy development. The theory underlying the model is based on Samuelson, et al.'s (1986) work and Wilke's (1991) elaboration of it as the Greed/Efficiency/Fairness (GEF) hypothesis of motivation in the management of resource dilemmas, and behavioral economics informed by Kahneman and Thaler's prospect theory. ^ The model developed in this paper employs ordered probit econometric techniques applied to data derived from U.S. polls taken from 1990 to mid-2003 that measured support for health reform proposals. Outcome data are four-tiered Likert counts; independent variables are dummies representing the presence or absence of operationalizations of each behavioral variable, along with an integer representing policy process stage. Marginal effects of each independent variable predict how support levels change on triggering that variable. Model estimation results indicate a vanishingly small likelihood that all coefficients are zero and all variables have signs expected from model theory. ^ Three hypotheses were tested: support will drain from health reform policy as it becomes increasingly well-articulated and approaches enactment; reforms appealing to fairness through universal health coverage will enjoy a higher degree of support than those targeted more narrowly; health reforms calling for government operation of the health finance system will achieve lower support than those that do not. Model results support the first and last hypotheses. Contrary to expectations, universal health care proposals did not provide incremental support beyond those targeted to “deserving” populations—children, elderly, working families. In addition, loss of autonomy (e.g. restrictions on choice of care giver) is found to be the “third rail” of health reform with significantly-reduced support. When applied to a hypothetical health reform in which an employer-mandated Medical Savings Account policy is the centerpiece, the model predicts support that may be insufficient to enactment. These results indicate that the method developed in the paper may prove valuable to health policy designers. ^

The Moderating Role of Electoral Pressure on Congressional Ideological Polarization: A Cross-Sectional Time-Series Analysis

Reelection and self-interest are recurring themes in the study of our congressional leaders. To date, many studies have already been done on the trends between elections, party affiliation, and voting behavior in Congress. However, because a plethora of data has been collected on both elections and congressional voting, the ability to draw a connection between the two provides a very reasonable prospect. This project analyzes whether voting shifts in congressional elections have an effect on congressional voting. Will a congressman become ideologically more polarized when his electoral margins increase? Essentially, this paper assumes that all congressmen are ideologically polarized, and it is elections which serve to reel congressmen back toward the ideological middle. The election and ideological data for this study, which spans from the 56th to the 107th Congress, finds statistically significant relationships between these two variables. In fact, congressman pay attention to election returns when voting in Congress. When broken down by party, Democrats are more exhibitive of this phenomenon, which suggest that Democrats may be more likely to intrinsically follow the popular model of representation. Meanwhile, it can be hypothesized that insignificant results for Republicans indicate that Republicans may follow a trustee model of representation.

Asset Pricing with Heterogeneous Agents, Incomplete Markets and Trading Constraints

The consumption capital asset pricing model is the standard economic model used to capture stock market behavior. However, empirical tests have pointed out to its inability to account quantitatively for the high average rate of return and volatility of stocks over time for plausible parameter values. Recent research has suggested that the consumption of stockholders is more strongly correlated with the performance of the stock market than the consumption of non-stockholders. We model two types of agents, non-stockholders with standard preferences and stock holders with preferences that incorporate elements of the prospect theory developed by Kahneman and Tversky (1979). In addition to consumption, stockholders consider fluctuations in their financial wealth explicitly when making decisions. Data from the Panel Study of Income Dynamics are used to calibrate the labor income processes of the two types of agents. Each agent faces idiosyncratic shocks to his labor income as well as aggregate shocks to the per-share dividend but markets are incomplete and agents cannot hedge consumption risks completely. In addition, consumers face both borrowing and short-sale constraints. Our results show that in equilibrium, agents hold different portfolios. Our model is able to generate a time-varying risk premium of about 5.5% while maintaining a low risk free rate, thus suggesting a plausible explanation for the equity premium puzzle reported by Mehra and Prescott (1985).

THE EFFECTS OF COST-SHARING ON USE OF SERVICES AND CONSUMER CHARACTERISTICS IN A STATE'S CRIPPLED CHILDREN'S DIVISION

The present study analyzed some of the effects of imposing a cost-sharing requirement on users of a state's health service program. The study population consisted of people who were in diagnosed medical need and included, but was not limited to, people in financial need.^ The purpose of the study was to determine if the cost-sharing requirement had any detrimental effects on the service population. Changes in the characteristics of service consumers and in utilization patterns were analyzed using time-series techniques and pre-post policy comparisons.^ The study hypotheses stated that the distribution of service provided, diagnoses serviced, and consumer income levels would change following the cost-sharing policy.^ Analysis of data revealed that neither the characteristics of service users (income, race, sex, etc.) nor services provided by the program changed significantly following the policy. The results were explainable in part by the fact that all of the program participants were in diagnosed medical need. Therefore, their use of "discretionary" or "less necessary" services was limited.^ The study's findings supported the work of Joseph Newhouse, Charles Phelps, and others who have contended that necessary service use would not be detrimentally affected by reasonable cost-sharing provisions. These contentions raise the prospect of incorporating cost-sharing into programs such as Medicaid, which, at this writing, do not demand any consumer payment for services.^ The study concluded with a discussion of the cost-containment problem in health services. The efficacy of cost-sharing was considered relative to other financing and reimbursement strategies such as HMO's, self-funding, and reimbursement for less costly services and places of service. ^

The influence of antibacterial susceptibility and pharmacodynamics on the therapeutic response of infection

This prospective cohort study estimated how antibacterial resistance affected the time until clinical response. Relative rates of improvement and cure were estimated by proportional-hazards regression for 391 patients with culture-confirmed bacterial keratitis who had the ciprofloxacin minimal inhibitory concentration (MIC) measured of the principal corneal isolate and who were treated with ciprofloxacin 0.3% solution or ointment. After adjusting for age and hypopyon status and stratifying by ulcer size, clinic, and ciprofloxacin formulation, the summary rate of clinical improvement with ciprofloxacin therapy was reduced by 42% (95% confidence limits [CL], 3%, 65%) among patients whose corneal isolate's ciprofloxacin MIC exceeded 1.0 μg/mL compared to those with more sensitive isolates. The summary rate of resolution to improvement and cure was reduced by 36% (95% CL, 11%, 53%) among corneal infections having a higher ciprofloxacin MIC. Rate ratios were modified by the size of the presenting corneal ulceration; for ulcer diameters of 4 mm or less and of more than 4 mm, improvement rate ratios were 0.56 (95% CL, 0.31, 1.02) and 0.65 (95% CL, 0.23, 1.80), respectively; resolution rate ratios were 0.63 (95% CL, 0.44, 0.91) and 0.67 (95% CL, 0.32, 1.39), respectively. Sensitivity analysis showed that the summary improvement rate ratio could be maximally overestimated by 24% (95% CL, −29%, 114%) because of informative censoring or by 33% (95% CL, −21%, 126%) from loss to follow up. Based on reported corneal pharmacokinetics of topical ciprofloxacin, the probability of clinical improvement was 90% or more if the ratio of the achievable corneal ciprofloxacin concentration to the corneal isolate's ciprofloxacin MIC was above 8 or the ratio of the area under the 24-hour corneal concentration curve to the ciprofloxacin MIC was greater than 151. This study suggests that corneal infections by bacteria having a higher ciprofloxacin MIC respond more slowly to ciprofloxacin treatment than those with a lower MIC. While the rate of clinical resolution is affected by patient age and clinical severity, antimicrobial susceptibility testing of corneal cultures can indicate the relative effectiveness of antibacterial therapy. A pharmacodynamic approach to treating bacterial keratitis offers the prospect of optimal antimicrobial selection and modification. ^

Tutaque sit inter inprobos innocentia : aspectos teóricos e práticos sobre os limítes da autoridade régia no reino hispano-visigodo de Toledo segundo as fontes júridicas e conciliares do reinado de Chintila (636-640).

Las construcciones teóricas elaboradas a lo largo de la Antigüedad Tardía buscaban, en su gran mayoría, poner en destaque la autoridad y el poder que deberían ser ejercidos por el rey en el espacio geográfico de su reino. Además de la evidente herencia del pensamiento político clásico romano, que ya apuntaba la supremacía teórica del magistrado o del princeps respecto al cuerpo social y político, el modelo cristiano del princeps christianus sacratissimus, que se construye a partir del siglo IV, ofrecía la perspectiva de que el gobernante debería imponer las leyes para hacer valer la justicia a los inocentes. Tales ideas se mantuvieron en el reino hispanovisigodo de Toledo y para tanto tenemos indicios en las fuentes isidorianas, conciliares y leges antiquas. Sin embargo, la antitesis entre teoría y el ejercicio práctico del poder se presenta muy claramente en las disputas nobiliarias afectando directamente el poder del rey y todas sus atribuciones. Es el caso del reinado de Chintila (636-640), en el cuál la ley tenía como principal objetivo la protección de los grupos de apoyo político del monarca.

Economia solidária e trabalho coletivo : Um olhar sobre a Cooperativa do Riachão no Norte de Minas Gerais - Brasil

It is intended to discuss the prospect of collective work in solidarity economy, from experiences with those of the Cooperative Riachao workers, located in a rural community in the municipality of Montes Claros, Minas Gerais / Brazil, this approximately 240 farming families extractive are benefited with the generation of jobs and income through initiatives grounded in associations, cooperatives and collectives. Among the 80 to 90 years, appeared inBrazil experiences of solidarity, resulting economy of the labor market crisis and rising unemployment, and an important response to the workers in relation to changes in the world of work. It is grounded in the organization of groups of workers, by way of solidarity, community, cooperation, and self-management reactions. In this sense, we intend to present the achievements, challenges and dilemmas of workers COOPERIACHAO, around a project that aims at empowerment of social actors and social transformation of the subject

El progreso de microrregionalización como estrategia del desarrollo local : Un estudio de la provincia de Chaco

El artículo analiza la experiencia de desarrollo llevada a cabo por el gobierno del Chaco, Argentina, entre los años 2000 y 2007 mediante la organización del territorio provincial en microrregiones. El énfasis ha sido puesto en los aspectos participativos y en el sentido que el proceso adquirió para sus propios actores. La noción de territorio, en su vinculación con el término ?campo? de Bourdieu, constituyó un concepto relevante a los efectos del análisis. En primer lugar, se explicitan los ejes teóricos del discurso oficial que origina y promueve el proceso: la opción por el desarrollo sustentable, la perspectiva de integración de lo económico con lo social y la generación de espacios participativos para la gestión de las políticas públicas. En la descripción de la experiencia se identifican las tensiones, actores y lógicas subyacentes: iniciativas y razones para la creación de cada microrregión, modalidad de la participación, consecuencias y obstáculos. El análisis muestra que la tensión entre los intereses económicos de los sectores productivos más estabilizados y las expectativas sociales de los sectores vulnerados no logra dirimirse, por lo cual la voluntad asociativa discurre en el marco de esta lógica. El Estado no puede ser un actor prescindente. Estos procesos deben contribuir a afirmar la identidad cultural y el sentido de pertenencia desde una perspectiva que reconozca la diversidad pero no legitime la desigualdad. En este contexto, se destaca la importancia de abrir espacios que permitan nuclear a la población de las distintas jurisdicciones para la discusión de ejes, la definición de políticas y la construcción de consensos que incluyan el reconocimiento del otro como igual, fortaleciendo los mecanismos de cohesión social

Territorio y prospección social : Un aporte para el análisis de la evolución de la sociabilidad urbana en Argentina

En este artículo se postula que la geografía posee una cierta capacidad para establecer marcos analíticos que sirven a la prospectiva en ciencias sociales. Para ello se acude a las posibilidades del análisis multiescalar como instrumento que, partiendo de los procesos territoriales estudiados a diferentes escalas, da cuenta también de los diferentes tempos que los afectan. Esas distintas temporalidades, al conjugarse en determinados espacios, ponen condiciones a los desarrollos futuros que son de interés para el análisis sociológico. Las actuales condiciones en que se desarrolla la sociedad urbana argentina son analizadas desde esta perspectiva.
