Indebted to development: microcredit as (de)marginalisation in rural China

Microcredit schemes have been increasingly incorporated into development policies that aim to de-marginalise rural China. Based on in-depth ethnographic fieldwork, this paper examines the various roles that microcredit programmes play in development outcomes at the local level. It demonstrates that microcredit has the ability to facilitate the de-marginalisation of certain individuals/groups, while simultaneously (re)producing inequalities, thus exacerbating the marginalisation of others. This finding demonstrates that microcredit does not induce uniform, predictable and linear development through the integration of marginal places and people into the formal financial system and wider economy. Instead, microcredit programmes reflect and reinforce the interlocking sets of unequal relationships that are the root cause of marginality and underdevelopment in China. Through this detailed analysis of the contradictory outcomes of Chinese microcredit programmes, this paper provides the basis for a wider relational critique of microcredit as an intervention aimed at inducing a specific type of market-oriented linear development that is beneficial for some and detrimental for others.     

An Insider–Outsider Theory of Popular Tolerance for Corrupt Politicians

This article addresses the puzzle of electoral support for corrupt politicians in emerging democracies by examining citizens’ varying attitudes toward political corruption. We make an important theoretical distinction between perceptions of and tolerance for corruption, and argue that these different attitudes vary across individuals depending on whether they are political insiders or outsiders. We test our theory using Afrobarometer survey data from 18 sub‐Saharan African countries and find that individuals included within clientelistic networks simultaneously perceive corruption as ubiquitous and are more tolerant of malfeasance. Meanwhile, those individuals with partisan or ethnic ties to the incumbent are less likely to consider corruption as widespread. Finally, we explore whether variation in attitudes toward corruption influences citizens’ voting behavior, and find that insiders are less likely to “vote the rascals out.”     

Evaluation of DNA Extraction Methods for Processing Fingerprint Powder-Coated Forensic Evidence

In unison, fingerprinting and DNA analysis have played a pivotal role in forensic investigations. Fingerprint powders that are available on the market can come in a range of colors and with specific properties. This study evaluated the efficiency of DNA extraction from samples coated with 3 brands of fingerprint powders: Lightning, Sirchie, and SupraNano, covering a range of colors and properties. A total of 23 fingerprint powders were tested using the Chelex, Promega DNA IQ™, and Applied Biosystems™ PrepFiler™ DNA extraction protocols. The DNA IQ™ and PrepFiler™ methods extracted higher yields of DNA in comparison to Chelex, which also accounted for better quality of PowerPlex x00AE; 21 DNA profiles recovered. There were no signs of degradation or inhibition in the quantification data, indicating that samples returning low DNA yield was due to interference during DNA extraction and not PCR inhibition. DNA profiles were recovered from the majority of fingerprint powders with only a single powder, Sirchie Magnetic Silver, failing to produce a profile using any of the methods tested. A link was observed between the DNA extraction chemistry, fingerprint powder property, that is, nonmagnetic, magnetic and aqueous, and the brand of fingerprint powder. Overall, the DNA IQ™ method was favorable for nonmagnetic fingerprint powders, while magnetic fingerprint powders produced more DNA profiles when extracted with the PrepFiler™ chemistry. This study highlights the importance of screening DNA extraction chemistries for the type of fingerprint powder used, as there is not a single DNA extraction method that suits all fingerprint powder brands and properties.     

Meeting peasants where they are: cultivating agroecological alternatives in neoliberal Guatemala

ABSTRACT

Social movements increasingly embrace agroecology as an integral part of food sovereignty. This essay has two related aims: first, to highlight the barriers to agroecology and explore how these can be overcome; second, to deepen understandings of how agroecology can strengthen movements for food sovereignty or extend neoliberal governance. I ground these questions by examining state and social movement agroecological programs in Guatemala. I argue that strict rejection of conventional inputs and market production, in addition to insufficient state investment and redistribution, creates barriers to participation among a rural peasantry whose livelihoods have been transformed by decades of scientific, market-led development. Facing these limits, agroecology can work to strengthen food sovereignty movements, but can also reinforce the neoliberal food regime by promoting resilience and indigenous agriculture as sufficient to resolve the food crisis.     

An econometric analysis of counterterrorism effectiveness: the impact on life and property losses

This paper investigates authorities’ relative counterterrorism effectiveness focusing on its behavior over time, its impact on casualties and property losses. Using data on transnational terrorism from the ITERATE database (1973–2003) and discrete choice models, relative counterterrorism effectiveness is evaluated controlling for a variety of terrorists’ and authorities’ effort attributes. The probability of a terrorist incident being stopped by the authorities has increased in the examined period. Furthermore, a negative relationship between authorities’ ability to stop an incident and the probabilities of casualties and damages is identified. However, the “ability to stop” exerts higher impact on the probability of property losses compared to casualties.     

Trading policy: Constituents and party in U.S. trade policy

Studies of US trade policy legislation focus on the effect of constituents on trade policy voting and give less weight to institutions such as political parties. To demonstrate that political parties affect voting, I compare the votes of politicians who share constituency characteristics but differ in political party affiliation. This approach requires less reliance on assumptions about, or empirical measures of, constituents’ trade preferences. The results demonstrate that political parties play a significant role in legislative voting on trade policy. Theories of political economy therefore should incorporate how constituency interests and partisan pressures affect legislative voting.     

Preparation of Tool Mark Standards with Jewelry Modeling Waxes

Abstract:  This paper presents how jewelry modeling waxes are used in the preparation of tool mark standards from exemplar tools. We have previously found that jewelry modeling waxes are ideal for preparing test tool marks from exemplar tools. In this study, simple methods and techniques are offered for the replication of accurate, highly detailed tool mark standards with jewelry modeling waxes. The techniques described here demonstrate the conditioning and proper use of jewelry modeling wax in the production of tool mark standards. The application of each test tool's working surface to a piece of the appropriate wax in a manner consistent with the tool's design is clearly illustrated. The resulting tool mark standards are exact, highly detailed, 1:1, negative impressions of the exemplar tool's working surface. These wax models have a long shelf life and are suitable for use in microscopic examination comparison of questioned and known tool marks.     

Estimation and evidence in forensic anthropology: age-at-death

A great deal has previously been written about the use of skeletal morphological changes in estimating ages-at-death. This article looks in particular at the pubic symphysis, as it was historically one of the first regions to be described in the literature on age estimation. Despite the lengthy history, the value of the pubic symphysis in estimating ages and in providing evidence for putative identifications remains unclear. This lack of clarity primarily stems from the fact that rather ad hoc statistical methods have been applied in previous studies. This article presents a statistical analysis of a large data set (n = 1766) of pubic symphyseal scores from multiple contexts, including anatomical collections, war dead, and victims of genocide. The emphasis is in finding statistical methods that will have the correct "coverage."Coverage" means that if a method has a stated coverage of 50%, then approximately 50% of the individuals in a particular pubic symphyseal stage should have ages that are between the stated age limits, and that approximately 25% should be below the bottom age limit and 25% above the top age limit. In a number of applications it is shown that if an appropriate prior age-at-death distribution is used, then "transition analysis" will provide accurate "coverages," while percentile methods, range methods, and means (+/-standard deviations) will not. Even in cases where there are significant differences in the mean ages-to-transition between populations, the effects on the stated age limits for particular "coverages" are minimal. As a consequence, more emphasis needs to be placed on collecting data on age changes in large samples, rather than focusing on the possibility of inter-population variation in rates of aging.     

Statistical discrimination of liquid gasoline samples from casework

The intention of this study was to differentiate liquid gasoline samples from casework by utilizing multivariate pattern recognition procedures on data from gas chromatography-mass spectrometry. A supervised learning approach was undertaken to achieve this goal employing the methods of principal component analysis (PCA), canonical variate analysis (CVA), orthogonal canonical variate analysis (OCVA), and linear discriminant analysis. The study revealed that the variability in the sample population was sufficient enough to distinguish all the samples from one another knowing their groups a priori. CVA was able to differentiate all samples in the population using only three dimensions, while OCVA required four dimensions. PCA required 10 dimensions of data in order to predict the correct groupings. These results were all cross-validated using the "jackknife" method to confirm the classification functions and compute estimates of error rates. The results of this initial study have helped to develop procedures for the application of multivariate analysis to fire debris casework.     

A Genetic Basis for Social Trust?

A propensity to believe that fellow citizens will not act against our interests in social and economic transactions has been identified as key to the effective functioning of democratic polities. Yet the causes of this type of ‘generalized’ or ‘social’ trust are far from clear. To date, researchers within the social and political sciences have focused almost exclusively on social-developmental and political/institutional features of individuals and societies as the primary causal influences. In this paper we investigate the intriguing possibility that social trust might have a genetic, as well as an environmental basis. We use data collected from samples of monozygotic and dizygotic twins to estimate the additive genetic, shared environmental, and non-shared environmental components of trust. Our results show that the majority of the variance in a multi-item trust scale is accounted for by an additive genetic factor. On the other hand, the environmental influences experienced in common by sibling pairs have no discernable effect; the only environmental influences appear to be those that are unique to the individual. Our findings problematise the widely held view that the development of social trust occurs through a process of familial socialization at an early stage of the life course.
