The Food Preferences of the Blow Fly Lucilia cuprina Offered Human Blood,Semen and Saliva,and Various Nonhuman Foods Sources

As human DNA profiles can be obtained from blow fly artifacts, this study aimed to establish the feeding preferences of Lucilia cuprina (Wiedemann) blow flies when offered human biological fluids and nonhuman food sources. One‐day‐old and 3‐day‐old blow flies of both sexes were simultaneously offered human blood, semen and saliva, pet food, canned tuna and honey, and the number and length of visits documented over 6 h. One‐day‐old flies visited pet food and honey most often, but stayed longest on honey and semen. Three‐day‐old flies visited semen and pet food most often, and stayed longest on these food sources. Blood and saliva were the least preferred options for all flies. Overall, flies preferred dry blood and semen to the wet forms. These findings demonstrate that even when other food sources are available, flies at a crime scene may feed on human biological fluids if present, potentially transferring human DNA.     

Political Dynasties in the UK House of Commons: The Null Effect of Narrow Electoral Selection

Does power persist within families? This article considers whether members of the UK House of Commons with longer legislative careers after 1832 were more likely to establish a political dynasty. Tenure can create opportunities to promote relatives. A regression discontinuity design for re‐election races helps to rule out the confounding influence of inheritable traits. There is no evidence for a causal effect of tenure length on establishing or continuing a dynasty. Established families may have constrained further dynasty development, explaining the null result of tenure.     

Gender Differences in Resistance to Schooling: The Role of Dynamic Peer-Influence and Selection Processes

Boys engage in notably higher levels of resistance to schooling than girls. While scholars argue that peer processes contribute to this gender gap, this claim has not been tested with longitudinal quantitative data. This study fills this lacuna by examining the role of dynamic peer-selection and influence processes in the gender gap in resistance to schooling (i.e., arguing with teachers, skipping class, not putting effort into school, receiving punishments at school, and coming late to class) with two-wave panel data. We expect that, compared to girls, boys are more exposed and more responsive to peers who exhibit resistant behavior. We estimate hybrid models on 5448 students from 251 school classes in Sweden (14–15 years, 49% boys), and stochastic actor-based models (SIENA) on a subsample of these data (2480 students in 98 classes; 49% boys). We find that boys are more exposed to resistant friends than girls, and that adolescents are influenced by the resistant behavior of friends. These peer processes do not contribute to a widening of the gender gap in resistance to schooling, yet they contribute somewhat to the persistence of the initial gender gap. Boys are not more responsive to the resistant behavior of friends than girls. Instead, girls are influenced more by the resistant behavior of lower status friends than boys. This explains to some extent why boys increase their resistance to schooling more over time. All in all, peer-influence and selection processes seem to play a minor role in gender differences in resistance to schooling. These findings nuance under investigated claims that have been made in the literature.     

Lobbying and asymmetric information

Informational lobbying — the use by interest groups of their (alleged) expertise or private information on matters of importance for policymakers in an attempt to persuade them to implement particular policies — is often regarded as an important means of influence. This paper analyzes this phenomenon in a game setting. On the one hand, the interest group is assumed to have private information which is relevant to the policymaker, whilst, on the other hand, the policymaker is assumed to be fully aware of the strategic incentives of the interest group to (mis)report or conceal its private information. It is shown that in a setting of partially conflicting interests a rationale for informational lobbying can only exist if messages bear a cost to the interest group and if the group's preferences carry information in the ‘right direction’. Furthermore, it is shown that it is not the content of the message as such, but rather the characteristics of the interest group that induces potential changes in the policymaker's behavior. In addition, the model reveals some interesting results on the relation between, on the one hand, the occurrence and impact of lobbying and, on the other hand, the cost of lobbying, the stake which an interest group has in persuading the policymaker, the similarity between the policymaker's and the group's preferences, and the initial beliefs of the policymaker. Moreover, we relate the results to some empirical findings on lobbying. qu]Much of the pressure placed upon government and its agencies takes the form of freely provided “objective” studies showing the important outcomes to be expected from the enactment of particular policies (Bartlett, 1973: 133, his quotation marks). qu]The analysis here is vague. What is needed is an equilibrium model in which lobbying activities have influence. Incomplete information ought to be the key to building such a model that would explain why lobbying occurs (information, collusion with decision makers, and so on) and whether lobbying expenses are socially wasteful. (Tirole, 1989: Ch. 1.3, p. 77, Rentseeking behavior).     

The impact of plurilateral trade agreements on developing countries – to participate or not to participate?

In the wake of the impasse in the Doha Development Round of multilateral trade talks, sector-specific plurilateral trade agreements (PTAs) have been gaining traction. However, PTAs mostly appeal to developed countries, with the uptake among developing countries (including least-developed countries) being very limited. This article investigates the factors contributing to such a phenomenon, whether there is indeed merit in developing countries playing a more active role in PTAs and how they might be encouraged to do so. Both qualitative and quantitative analyses were conducted with specific attention being given to the effects, on a selection of developing countries, of participation in four PTAs: the Trade in Services Agreement, the Government Procurement Agreement, the Environmental Goods Agreement and the Information Technology Agreement II. Among the findings was that although, according to the qualitative analysis, policymakers are generally disinterested in the four PTAs because they are not aligned to the countries’ economic interests or they threaten policy space, the quantitative analysis revealed that gains could often be made from more active participation in these agreements. This clearly points to a research gap and highlights the need for more in-depth analysis of the potential of PTAs in the developing world.     

Justice and Feelings: Toward a New Era in Justice Research

In this special issue, the relationship between feelings and justice and its consequences are highlighted. Five articles discuss the role that affect, feelings, and emotions play in justice processes across a variety of social settings. In the present introductory article, the position of past and present justice research in relationship to these topics is briefly reviewed. In addition, reasons are outlined to show why a focus on these issues may be pivotal for a better understanding of social justice and how this may pave the way for a new, more process-oriented era in social justice research, focusing more on “hot” cognitive aspects as they pertain to social justice concerns.     

Implementing randomized experiments in criminal justice settings: An evaluation of multi-systemic therapy in the Netherlands

This paper addresses several issues that we encountered when implementing a randomized experiment to evaluate a promising intervention for serious juvenile delinquents, multi-systemic therapy (MST). The issues overlap with issues others experienced when trying to conduct randomized experiments in clinical practice, but are complicated because MST takes place in a legal context. The complex juvenile justice system makes it difficult to come up with a simple system of randomization. Problems encountered are the complexity of the referral process in this type of intervention, legal issues and the ethical concerns raised by clinicians. Our experiences might be useful to others planning to carry out a randomized efficacy study within the juvenile justice system. Firstly, other researchers might feel supported if they realize that others experience similar problems, and, secondly, we provide some concrete suggestions concerning the following: selecting the procedures and determining the moment of randomization, dealing with and overcoming the resistance of institutions involved, maintaining the cooperation of both the institution and the sample, and keeping turnover of research staff to a minimum.
