Career De-Separation in Westminster Democracies

In Westminster parliamentary systems there was once a clear separation between the careers of public servants and of elected politicians. Politicians decided what policies they wanted to pursue, while public servants advised, devised and delivered the policies. This separation ensured that policy ideas were developed by a professional elite with experience and knowledge. Politicians came from a variety of backgrounds, entering politics for a variety of reasons. Over time, the source of policy advice for ministers has shifted from the professional public servant to political advisers lacking experience and with different career ambitions than public service. Increasingly, elected politicians are becoming ‘professionalised’—emerging from similar party and adviser backgrounds. The de-separation of what were once distinct career paths has led to poorer policy development, increasing public malfeasance, a lower-quality civil service, and democratic disenchantment. We need to separate the career paths once more.     

The use of error rates to predict and characterize the efficacy of presumptive field tests

From a forensic perspective, a presumptive test, one which indicates the presence or absence of a certain target material such as blood, is an invaluable tool. Among these tests, there are different specificities, sensitivities, and shelf lives. The accuracy of a test is an algebraic combination of the specificity and sensitivity of the test. Each test has limitations as given by its false positive and false negative rates. The aim of this study was to illustrate how the false positive and false negative rates are to be properly determined using a simulation study for the phenolphthalein test. New presumptive tests must be properly evaluated/validated through testing of commonly encountered household items and other potentially probative items usually found at crime scenes, however, the makeup of test sets must appropriately capture all error rates. In order to correctly use these results when the test is applied to an unknown sample recovered at a crime scene, the error rates cannot be applied directly to estimate whether or not the sample is actually the analyte of interest. In a validation study, the forensic scientist calculates the false positive rate as the p(Positive Reaction|Blood), whereas at the scene, the crime scene investigator wishes to determine the p(Blood|Positive Reaction). All crime scene investigators need to ensure that the conditional is not transposed when interpreting such results. Furthermore, this work provides a model for the assessment of a multiple test diagnostic system intended for investigators.     

Timing and Appearance of Postmortem Root Banding in Nonhuman Mammals,

A study was undertaken using nonhuman mammal specimens to better understand environmental influences on postmortem hair root band (PMRB) formation and to see whether PMRBs would occur in nonhuman mammal hairs in a similar fashion to human hairs. Carcasses from surrounding roadways were the primary source of specimens for this study, augmented by donated deceased domestic pets. Sections of pelt from each specimen were placed in controlled environmental conditions while the remainder of the carcass was left in a secure outdoor setting. Hair samples were collected daily from outdoor and control specimens and examined for evidence of PMRBs. Several environmental factors were also recorded on a daily basis. Results demonstrate PMRBs can occur in nonhuman mammal hairs, and they have microscopic characteristics similar to human PMRBs. Factors found to correlate with PMRB formation include postmortem interval, temperature, pH, and the formation and subsequent volatilization of ammonia from the surrounding tissue.     

The downsides of information transmission and voting

I analyze a model of information transmission in collective choice environments. An Expert possesses private information about the consequences of passing an exogenous proposal and engages in cheap talk to persuade voters to pass or reject the proposal. The Expert may successfully persuade the voters to take her preferred action even when all or most voters would receive a better ex ante payoff with no information transmission. I consider several remedies that an institutional designer may consider in order to avoid this problem while allowing information transmission that benefits the voters. I evaluate the effects of (1) limiting Expert communication to binary endorsements, (2) encouraging competition between Experts, and (3) restricting the agenda in order to consider only one dimension at a time. None of these proposals completely eliminate negative persuasion outcomes, but limiting the Expert to binary endorsements avoids the worst manipulation while preserving beneficial information transmission.     

Combining autoethnography and multimodal social semiotics: potentials for theory and method

Different methodological approaches allow varying access to the objects of inquiry and enable one to ask different kinds of questions. This paper explores the possibilities that emerge through the combination of multimodal social semiotics and autoethnography. We discuss the epistemological and methodological bases for each approach and show the potentials in combining them. Drawing on an autoethnographic study in civil engineering, we argue that three aspects of research inquiry are enhanced through the combination of these approaches. These three aspects include a greater understanding of social context and its impact on meaning-making; an awareness of the multimodal nature of meaning-making; and an understanding of the ways in which the “interest” of the researcher (as participant) manifests in texts. Overall, we argue that these approaches augment each other in generative ways and allow for an in-depth look at how texts are embedded in particular practices and communities.     

Using Cultural Theory to Analyze the Metagovernance of the Nuclear Renaissance in Britain,France, and the United States

The governments of Britain, France, and the United States are seeking to promote renewed investment in nuclear power through metagovernance. Metagovernance describes the way governments can leverage state power and resources to shape the behavior of networked actors to advance policy goals. To metagovern, governments use a variety of policy tools but the factors shaping the design of these policy tools remains unclear. Grid‐group cultural theory is used to show that the design of the policy tools used in metagovernance reflects both an underlying cultural bias within government and prevailing institutional circumstances. The paper demonstrates the utility of cultural theory in the study of metagovernance.     

Defending the Articles of Conferation: A Response to Sobel

A fundamental mystery of the Articles of Confederation is why the statescontributed sizeable resources to the confederation government when theywere allegedly caught in a collective action problem. In a recent article,Russel Sobel denies the collective action problem and suggests that ourresearch on the incentive structure of the confederation contradicts theevidence. This note clarifies both of our arguments, introduces the typeof evidence that would determine whether national public goods weresub-optimally supplied, and explains why states contributed in a mannerthat is consistent with the evidence and with a deficient institutionaldesign.
