The Welfare Effects of Balance of Payments Reform: A Micro-Macro Simulation of the Cost of Rent-Seeking

This article proposes a methodology for analysing the effect of balance of payments liberalisation on measures of poverty and distribution and applies it to the case of Jamaica in the 1990s. The methodology consists of a macro-micro simulation in which a CGE model provides labour market outcomes, which in turn are used to manipulate the sectoral allocation of employment to generate the income distribution consistent with the new labour market outcome. In the application to Jamaica, we find that the reallocation of resources away from rent-seeking activities in the presence of exchange controls is significant and has large macroeconomic effects. Opening up of the current account has little effect on poverty, but liberalisation of the capital account reduces poverty, especially amongst the very poor. Neither policy change taken separately, nor the combination of the two, has more than a negligible effect on the distribution of income.     

X‐ray Scattering Evaluation of Ultrastructural Changes in Human Dental Tissues with Thermal Treatment

Micro‐ and ultrastructural analysis of burned skeletal remains is crucial for obtaining a reliable estimation of cremation temperature. Earlier studies mainly focused on heat‐induced changes in bone tissue, while this study extends this research to human dental tissues using a novel quantitative analytical approach. Twelve tooth sections were burned at 400–900°C (30‐min exposure, increments of 100°C). Subsequent combined small‐ and wide‐angle X‐ray scattering (SAXS/WAXS) experiments were performed at the Diamond Light Source synchrotron facility, where 28 scattering patterns were collected within each tooth section. In comparison with the control sample, an increase in mean crystal thickness was found in burned dentine (2.8‐fold) and enamel (1.4‐fold), however at a smaller rate than reported earlier for bone tissue (5–10.7‐fold). The results provide a structural reference for traditional X‐ray scattering methods and emphasize the need to investigate bone and dental tissues separately to obtain a reliable estimation of cremation temperature.     

In Vitro Effects of Household Products on Calliphoridae Larvae Development: Implication for Forensic Entomology

Several parameters can delay the first arrival of flies on a corpse and the subsequent development of the larvae. This study focuses on the development of Lucilia sericata (Diptera: Calliphoridae) (Meigen, 1826) on household chemical‐contaminated substrates. bleach, perfume, hydrochloric acid, caustic soda, insecticide, mosquito repellent, and gasoline in quantities consistent with an amount that could possibly be spilled on a corpse were mixed with beef liver to simulate contaminated fleshes. Larvae were bred at 25°C on these media until emergence. Four developmental parameters were followed: survival rates, development times, sex ratios, and adult sizes. Hydrochloric acid, insecticide, and gasoline killed all larvae. In low quantities, caustic soda and mosquito repellent increased the development time and decreased the adult size. However, high quantities of these chemicals killed all larvae. Lastly, bleach and perfume did not affect the survival rate and barely impacted the development time or adult size. These results demonstrate common household products spilled on a corpse can strongly affect the development of Calliphoridae larvae. The effects of such products should be considered in forensic entomology cases.     

Representations of reproductive citizenship and vulnerability in media reports of offshore surrogacy

In his elaboration of the concept of ‘reproductive citizenship’, Turner (Turner B.S., 2001. The erosion of citizenship. The British journal of sociology, 52 (2), 189–209) suggested something of a homogeneous accumulation of cultural capital to those who make a reproductive contribution to contemporary western societies. The present article takes up this suggestion and proposes that whilst reproduction is indeed a hallmark of contemporary citizenship, the cultural capital arising from this is still differentiated by mode of reproduction, with reproductive heterosex remaining the norm against which other modes are compared. This norm, it is suggested, produces what is termed here ‘reproductive vulnerability’, namely vulnerability arising from being located outside of the norm. Through an analysis of media representations of Australian people who have undertaken offshore surrogacy arrangements in India, this article demonstrates how reproductive vulnerability is highlighted only to be dismissed through recourse to the construction of those who undertake reproductive travel as agentic citizens. The article concludes by considering what it would take for an ethics of reproductive travel to exist; one in which multiple, incommensurable vulnerabilities are taken into account, and the representation of which encourages, rather than inhibits, careful thought about the reproductive desires of all people.     

Larval-mass effect: Characterisation of heat emission by necrophageous blowflies (Diptera: Calliphoridae) larval aggregates

Numerous Calliphoridae species larvae are necrophageous and develop on animal cadavers. During the feeding stages, a strong gregarious behaviour leads to the formation of large larval masses, allowing larvae to share digestive fluids. Furthermore, a mass of larvae emits heat, resulting in a local increase of temperature. Differences greater than 20°C between ambient and larval mass temperatures have already been observed, and the temperature of the mass can reach 50°C. Thus, larvae could benefit from this increased local temperature to speed up their development. This study focuses on the dynamic and characterisation of heat emission by Lucilia sericata (Diptera: Calliphoridae) (Meigen, 1826) larval masses. Experiments were performed under controlled conditions using several ambient temperatures and different numbers of larvae. Results indicate that heat emission depends on the instar and is strongly affected by available amount of food. Furthermore, according to the experimental data, the heat emission is also relative to the weight of the larval mass, the larvae number and the local temperature. These results also demonstrate that optimum ambient-temperature values ranging between 22°C and 25°C produce maximal heat-emission per larva. Furthermore, a feedback loop, involving heat exchanges and physiological and behavioural thermoregulation processes, appears inside aggregates. In the context of forensic cases and post-mortem interval (PMI) estimation, these results indicate that heat emission can occur even with "small" masses if they are composed of high number of second stage larvae. Furthermore, particular attention should be paid on cases involving L. sericata larvae at ambient temperature ranging from 22°C to 25°C, which appears to maximise the heat-emission process.     

Multimodal biometrics for identity documents (MBioID)

The MBioID initiative has been set up to address the following germane question: What and how biometric technologies could be deployed in identity documents in the foreseeable future? This research effort proposes to look at current and future practices and systems of establishing and using biometric identity documents (IDs) and evaluate their effectiveness in large-scale developments. The first objective of the MBioID project is to present a review document establishing the current state-of-the-art related to the use of multimodal biometrics in an IDs application. This research report gives the main definitions, properties and the framework of use related to biometrics, an overview of the main standards developed in the biometric industry and standardisation organisations to ensure interoperability, as well as some of the legal framework and the issues associated to biometrics such as privacy and personal data protection. The state-of-the-art in terms of technological development is also summarised for a range of single biometric modalities (2D and 3D face, fingerprint, iris, on-line signature and speech), chosen according to ICAO recommendations and availabilities, and for various multimodal approaches. This paper gives a summary of the main elements of that report. The second objective of the MBioID project is to propose relevant acquisition and evaluation protocols for a large-scale deployment of biometric IDs. Combined with the protocols, a multimodal database will be acquired in a realistic way, in order to be as close as possible to a real biometric IDs deployment. In this paper, the issues and solutions related to the acquisition setup are briefly presented.     

Ticket-splitting in mixed-member systems: on the importance of seat linkage between electoral tiers

Abstract

In mixed-member electoral systems, voters usually have two votes: a nominal and a list vote. According to some studies, voters are increasingly using them to cast a split-ticket vote. However, very little is known about whether the type of mixed-member system, and in particular whether the allocation of seats across tiers is linked or not, creates different sets of incentives for this behaviour. This article provides new insights into the topic by analysing survey data from seven countries and 18 elections since 1990. It is found that the proportion of split-ticket votes is greater in mixed-member proportional than in mixed-member majoritarian systems. The results suggest that voters understand the operation of the electoral system and its consequences for the distribution of seats among parties, and adapt their behaviour accordingly.     

Risk Factors and Drivers of Financial Sustainability in Local Government: An Empirical Study

The current international crisis in public finances has made financial sustainability a key issue for governments. Although the European Union (EU) and other international organisations have recommended governments to monitor demographic and economic variables, few studies have considered the influence of these variables on financial sustainability. This paper seeks to identify and analyse the drivers and risk factors that influence the financial sustainability of local government. The findings identify both risk factors (unemployment and population aged under 16 years) and drivers (budgetary outcome) of financial sustainability, which may constitute a useful basis for decision-taking by managers and policy-makers.
