Weighted Majoritarian Rules for the Location of Multiple Public Facilities

We consider collective decision problems given by a profile of single-peaked preferences defined over the real line and a set of pure public facilities to be located on the line. In this context, Bochet and Gordon (2012) provide a large class of priority rules based on efficiency, object-population monotonicity and sovereignty. Each such rule is described by a fixed priority ordering among interest groups. We show that any priority rule which treats agents symmetrically — anonymity — respects some form of coherence across collective decision problems — reinforcement — and only depends on peak information — peakonly — is a weighted majoritarian rule. Each such rule defines priorities based on the relative size of the interest groups and specific weights attached to locations. We give an explicit account of the richness of this class of rules.

Accident or homicide - virtual crime scene reconstruction using 3D methods

The analysis and reconstruction of forensically relevant events, such as traffic accidents, criminal assaults and homicides are based on external and internal morphological findings of the injured or deceased person. For this approach high-tech methods are gaining increasing importance in forensic investigations. The non-contact optical 3D digitising system GOM ATOS is applied as a suitable tool for whole body surface and wound documentation and analysis in order to identify injury-causing instruments and to reconstruct the course of event. In addition to the surface documentation, cross-sectional imaging methods deliver medical internal findings of the body. These 3D data are fused into a whole body model of the deceased. Additional to the findings of the bodies, the injury inflicting instruments and incident scene is documented in 3D. The 3D data of the incident scene, generated by 3D laser scanning and photogrammetry, is also included into the reconstruction. Two cases illustrate the methods. In the fist case a man was shot in his bedroom and the main question was, if the offender shot the man intentionally or accidentally, as he declared. In the second case a woman was hit by a car, driving backwards into a garage. It was unclear if the driver drove backwards once or twice, which would indicate that he willingly injured and killed the woman. With this work, we demonstrate how 3D documentation, data merging and animation enable to answer reconstructive questions regarding the dynamic development of patterned injuries, and how this leads to a real data based reconstruction of the course of event.

Ethical Consumption and Social Context: Experimental Evidence from Germany and the United States

This research examines the role of social context in ethical consumption, specifically, the extent to which anonymity and social control influence individuals' decisions to purchase organic and Fair Trade coffee. Our research design overcomes biases of prior research by combining framing and discrete choice experiments in a survey. We systematically vary coffee growing method (organic or not), import status (Fair Trade or not), flavor, and price across four social contexts that vary in degree of anonymity and normative social control. The social contexts are buying coffee online, in a large grocery store, in a small neighborhood shop, and for a meeting of a human rights group. Subjects comprise 1,103 German and American undergraduate students. We find that social context indeed influences subjects' ethical consumer decisions, especially in situations with low anonymity and high social control. In addition, gender, coffee buying, and subjective social norms trigger heterogeneity regarding stated ethical consumption and the effects of social context. These results suggest previous research has underestimated the relevance of social context for ethical consumption and overestimated altruistic motives of ethical consumers. Our study demonstrates the great potential of discrete choice experiments for the study of social action and decision making processes in sociology.

Uncertain Belongings. Absent mourning, burial, and post-mortem repatriations at the external border of the EU in Spain

Since the mid-1980s, migrants from North African and sub-Saharan countries have irregularly crossed the Strait of Gibraltar, in the hope of a better future for themselves and their families. Travelling in small, poorly equipped boats without experienced captains has cost the lives of myriad border crossers. Many of these bodies will never be recovered and the bereaved will never know whether their relatives and friends are alive or not. The bereaved are thus condemned to a state of not knowing and uncertainty. Exploring the junction of death and belonging, I firstly open a discussion about the enigmatic relation between a dead body and a dead person and argue for the importance of the physical presence of the body for mourning. Secondly, I show how the anonymity of dead border crossers and their uncertain belongings are generated, concealed, or rewritten. Following the story of an undertaker, I thirdly examine post-mortem border crossings. Depicting the power relations within identification processes, I outline the ambiguity of the term belonging by emphasising the constitutive significance of personal belongings such as clothes to restore a person’s identity. Reflecting on the ethical relationships which different actors (including the researcher) undertake with the deceased, I aim at gaining a better understanding of the multiple belonging of dead border crossers found on Spanish shores.

Mikro- versus Makroperspektive der retributiven Gerechtigkeit, Strafziele und die Forderung nach Strafe

Wie Personen auf Straftaten reagieren und welche Strafziele sie dabei verfolgen, war bisher kaum Gegenstand psychologischer Forschung. In der vorliegenden Arbeit wird die dimensionale Struktur der Präferenz von Strafzielen untersucht. In zwei Befragungen wurden juristischen Laien Fallgeschichten zur Beurteilung vorgelegt (Raubüberfall, Körperverletzung, Betrug, Vergewaltigung). Die multivariaten Auswertungen weisen eine hohe Übereinstimmung auf: Strafziele lassen sich durch die zwei voneinander unabhängigen Dimensionen Strafhärte und Mikro- versus Makroperspektive klassifizieren. Wird eine Makroperspektive eingenommen, so ist dies mit einer stärkeren Gewichtung von Gesellschaftsinteressen verbunden sowie mit der Präferenz für das Strafziel der positiven Generalprävention. Die Mikroperspektive ist hingegen mit der Überzeugung verbunden, dass Gerechtigkeit insbesondere aus der Perspektive der konkret Beteiligten herzustellen ist. Je nach geforderter Strafhärte geht die Mikroperspektive mit einem Bias entweder für das Opfer und das Strafziel der Vergeltung oder aber für den Täter und das Strafziel der Resozialisierung einher.

Development of a questionnaire measuring Attitudes towards Psychological Online Interventions–the APOI

BACKGROUND: Only a minority of people suffering from depression receive adequate treatment. Psychological Online Interventions (POIs) could help bridge existing treatment gaps and augment the effectiveness of current treatments. Apart from effectiveness, user acceptance of POIs must be achieved if such interventions are to be broadly implemented in existing health-care. Valid measurement tools examining attitudes towards POIs are lacking. Therefore, we examined the dimensionality of attitudes towards POIs, developed a novel questionnaire, the Attitudes towards Psychological Online Interventions Questionnaire (APOI), and gathered data to examine its reliability. METHODS: We recruited a sample of 1004 adults with mild to moderate depressive symptoms from a range of sources. We constructed a set of 35 items based on literature review as well as expert and patient queries. The initial items were subjected to an exploratory factor analysis (EFA) in a randomly selected subsample. A final set of 16 items was subjected to a confirmatory factor analysis (CFA) to cross-validate the factor structure in a separate subsample. RESULTS: The EFA revealed four dimensions: "Scepticism and Perception of Risks", "Confidence in Effectiveness", "Technologization Threat" and "Anonymity Benefits". The model fit in the CFA was excellent relating to all applied indices (χ(2)=105.816, p=.651; SRMR=.042; RMSEA=.013; CFI=.994) and the APOI total scale showed acceptable to good internal consistency. CONCLUSIONS: Further research with the APOI might facilitate the development and dissemination of POIs and, ultimately, help improve the quality of care for people experiencing depressive symptoms.

Racial Bias in Motor Vehicle Searches: Additional Theory and Evidence

Knowles, Persico, and Todd (2001) develop a model of police search and offender behavior. Their model implies that if police are unprejudiced the rate of guilt should not vary across groups. Using data from Interstate 95 in Maryland, they find equal guilt rates for African-Americans and whites and conclude that the data is not consistent with racial prejudice against African-Americans. This paper generalizes the model of Knowles, Persico, and Todd by accounting for the fact that potential offenders are frequently not observed by the police and by including two different levels of offense severity. The paper shows that for African-American males the data is consistent with prejudice against African-American males, no prejudice, and reverse discrimination depending on the form of equilibria that exists in the economy. Additional analyses based on stratification by type of vehicle and time of day were conducted, but did not shed any light on the form of equilibria that best represents the situation in Maryland during the sample period.

Penalty Enhancement for Hate Crimes: An Economic Analysis

The issue of bias-motivated crimes has attracted consderable attention in recent years. In this paper, we develop an economic framework to analyze penalty enhancements for bias-motivated crimes. We extend the standard model by introducing two different groups of potential victims of crime, and assume that a potential offender's benefits from a crime depend on the group to which the victim belongs. We begin with the assumption that the harm to an individual victim from a bias-motivated crime is identical to that from an equivalent non-hate crime. Nonetheless, we derive the result that a pattern of crimes disproportionately targeting an identifiable group leads to greater social harm. This conclusion follows both from a model where disparities in groups' victimization probabilities lead to social losses due to fairness concerns, as well as a model where potential victims have the opportunity to undertake socially costly victimization avoidance activities. In particular, penalty enhancements can reduce the incentives for avoidance activity, and thereby protect the networks of profitable interactions that link members of different groups. We also argue that those groups that are covered by hate crime statutes tend to be those whose characteristics make it especially likely that penalty enhancement is socially optimal. Finally, we consider a number of other issues related to hate crimes, including teh choice of sanctions from behind a Rawlsian 'veil of ignorance' concerning group identity.

Punishing the Innocent along with the Guilty: The Economics of Individual versus Group Punishment

Standard models of law enforcement involve the apprehension and punishment of a single suspect, but in many contexts, punishment is actually imposed on an entire group known to contain the offender. The advantages of .group punishment. are that the offender is punished with certainty and detection costs are saved. The disadvantage is that innocent individuals are punished. We compare individual and group punishment when social welfare depends on fairness, and when it depends on deterrence. We show that group punishment may dominate in the former case if the detection technology is ineffective but never in the latter case. We discuss our results in the context of several examples.

Deterrence and Incapacitation: Towards a Unified Theory of Criminal Punishment

Economic models of crime have focused primarily on the goal of deterrence; the goal of incapacitation has received much less attention. This paper adapts the standard deterrence model to incorporate incapacitation. When prison only is used, incapacitation can result in a longer or a shorter optimal prison term compared to the deterrence-only model. It is longer if there is underdeterrence, and shorter if there is overdeterrence. In contrast, when a fine is available and it is not constrained by the offender's wealth, the optimal prison term is zero. Since the fine achieves first-best deterrence, only efficient crimes are committed and hence, there is no gain from incapacitation.

Statistics of the National soil test database of France

In France, farmers commission about 250,000 soil-testing analyses per year to assist them managing soil fertility. The number and diversity of origin of the samples make these analyses an interesting and original information source regarding cultivated topsoil variability. Moreover, these analyses relate to several parameters strongly influenced by human activity (macronutrient contents, pH...), for which existing cartographic information is not very relevant. Compiling the results of these analyses into a database makes it possible to re-use these data within both a national and temporal framework. A database compilation relating to data collected over the period 1990-2009 has been recently achieved. So far, commercial soil-testing laboratories approved by the Ministry of Agriculture have provided analytical results from more than 2,000,000 samples. After the initial quality control stage, analytical results from more than 1,900,000 samples were available in the database. The anonymity of the landholders seeking soil analyses is perfectly preserved, as the only identifying information stored is the location of the nearest administrative city to the sample site. We present in this dataset a set of statistical parameters of the spatial distributions for several agronomic soil properties. These statistical parameters are calculated for 4 different nested spatial entities (administrative areas: e.g. regions, departments, counties and agricultural areas) and for 4 time periods (1990-1994, 1995-1999, 2000-2004, 2005-2009). Two kinds of agronomic soil properties are available: the firs one correspond to the quantitative variables like the organic carbon content and the second one corresponds to the qualitative variables like the texture class. For each spatial unit and temporal period, we calculated the following statistics stets: the first set is calculated for the quantitative variables and corresponds to the number of samples, the mean, the standard deviation and, the 2-,4-,10-quantiles; the second set is calculated for the qualitative variables and corresponds to the number of samples, the value of the dominant class, the number of samples of the dominant class, the second dominant class, the number of samples of the second dominant class.

La misión fundante de los apodos en La Reina Isabel cantaba rancheras de Rivera Letelier

En su novela La Reina Isabel cantaba rancheras, Rivera Letelier retrata el sórdido mundo de las pampas salitreras del norte de Chile. Los personajes que habitan estas regiones carecen por completo de nombre propio. En su lugar encontramos apodos a partir de los que el autor crea y recrea la historia de los viejos y prostitutas que habitaron estas oficinas salitreras. Más allá de la evidente intención cómica que persigue el autor de la novela, creemos que el apodo es el elemento estructurante tanto de los personajes como de la novela en general. Esto se debe a que la historia de la desaparición de la "última oficina salitrera" se entrelaza con la historia de los personajes que vivieron en ella. Los protagonistas de la novela se destacan gracias a sus apodos del resto de aquellos viejos que no hicieron ningún mérito para conseguirlo y por lo tanto están condenados al anonimato. Precisamente, son las características del apodo las que permiten al autor configurar a estos personajes que al lector le costará olvidar. Como primera característica, aludiremos a la calidad referencial del apodo frente al nombre propio. Esto se debe a que el mote surge de los defectos, virtudes o de cualquier otra circunstancia vivida por alguna persona. Esto permite que se establezca una relación causal entre apodo y persona. Por su parte, el nombre propio establece una relación casual con la persona a la que designa. Por otro lado, mientras el nombre propio es otorgado de una vez y para siempre. El apodo presenta como segunda característica la validez. Es decir, el apodo, necesariamente, esta circuscripto a un tiempo, a un espacio y sólo es válido para un grupo determinado. Esto se debe a que sólo dentro de estos parámetros el apodo podrá ser interpretado. Cuando se altera alguna de estas coordenadas, indefectiblemente, el apodo cambia.

La compleja construcción de la problemática de la seguridad : violencia y políticas públicas de seguridad a comienzos del siglo XXI

Los primeros diez años del nuevo siglo nos encuentran con un bagaje de producción científica y trabajos de campo a partir de los cuales podemos reflexionar sobre la importancia de abordar la violencia cuando hablamos de políticas públicas de seguridad en sociedades democráticas. Ello implica reconocer un recorte del tema y una toma de posición alrededor de la cual iremos reconstruyendo la problemática de la seguridad que va más allá del delincuente, la asociación del problema de la seguridad al problema del delito, la tipificación de delitos y las técnicas disciplinarias. Nuestra atención esta dirigida a la violencia, la política expresada en políticas públicas y la expresión de las subjetividades en el miedo a ser víctima.

Potpourri : Conjeturas y cavilaciones

Potpourri, la primera novela de Cambaceres, suscitó un importante debate moral acerca de los asuntos que trata, del estilo en que está escrita y de la displicencia de su narrador, a quien se asoció -sin mediaciones- con su autor. El artículo aborda ese estilo que en general se impugnó para proponer que es precisamente en la supuesta falta de forma y en el desapego a las convenciones, tanto como en la indolencia del narrador, donde radican su potencia narrativa y su carácter experimental. Siguiendo este hilo conceptual, se indagan ciertos aspectos específicos: el anonimato, el silbido, el chisme y los secretos a voces, y la arquitectura de la página
