STR-genotyping from human medieval tooth and bone samples

We extracted the DNA contained in samples of bones and teeth from 10 skeletons excavated from the Gravette site (400-1000 AD, south of France). Ancient DNA was analysed by autosomal short tandem repeats (STRs). The DNA present in these ancient remains appeared very degraded, but nevertheless, better conserved in tooth than in bone samples. Moreover, we showed that the DNA extracted from ancient dental pulp was not exempt from polymerase chain reaction (PCR) inhibitors, which could result from extreme DNA fragmentation. An adapted protocol with a supplementary step of purification removed this inhibition.     

The Impact of School Mental Health Services on Out-of-School Suspension Rates

The current study investigated whether the presence of school-based mental health clinicians in an urban school district was associated with reduced out-of-school suspension rates. Forty one elementary schools with expanded school mental health (ESMH) programs were compared to 41 schools without ESMH programs. Correlational analyses revealed associations between suspension outcomes and several school-level demographic variables including school attendance rate, percent of students in poverty, and percent of nonwhite students in the school. After controlling for these variables, however, results of stepwise linear regressions demonstrated no significant differences between ESMH and non-ESMH schools on suspension outcomes. Results of the current study suggest that the presence of ESMH clinicians will not necessarily impact suspension rates in an elementary school. Targeted and well-implemented approaches to address behaviors that lead to suspension, or school- and system-level policies to provide alternatives to suspensions, will likely be a better route to achieving this outcome.

Age-at-death estimation based on the study of frontosphenoidal sutures

Determination of age at the time of death based on the observation of cranial sutures has led to numerous studies with sometimes contradictory results. The initial hypothesis being that suture closure is part of an age-related physiological process, the conflicting results have been interpreted by various authors as secondary to the choice of sutures, under the co-existing influence of pathological factors or genetic factors, or even independent of age. Despite these differences, macroscopic methods remain much used in anthropology and in forensic medicine. In our work, we evaluated the value of the degree of closure of the frontosphenoidal suture in estimating age at death of mature subjects, with the secondary objective of establishing a linear regression which could be used in routine practice. The study concerned bone specimens from individuals whose age, sex and medical history were known. Macroscopic observation was carried out on the ectocranial and endocranial sides according to four stages of closure previously defined. 290 sutures were taken from a population of whom two-thirds were men. The method can be repeated and reproduced and the regression established shows the confidence range for average error to be +/-1.5 years. While this result is of interest in terms of precision in prediction for a group of people, the prediction range is too great (+/-23 years) to be applicable to a single individual as part of a forensic procedure.     

Economic resilience after the Great Recession: an examination of unreserved fund balance in Michigan counties

ABSTRACT

This paper examines fiscal slack, in the form of unreserved fund balance, as a tool used by local governments to enhance economic resilience. It adapts ecological, engineering, and organisational definitions of economic resilience and investigate their relevance to local financial management in the United States after the Great Recession in 2008. Using group-based trajectory modelling, we identify different strategies of fund balances used by Michigan counties. The change of fund balance does not delineate any pattern theorised by the resilience concepts. We also find different factors that motivate local officials to manage their fund balances differently. The study suggests a nuanced understanding of fiscal slack used by local governments for economic resilience that goes beyond unreserved fund balance.     

Social enterprise and work integration of North Korean migrants in South Korea

This contribution aims to present the general issue of integrating North Korean (NK) migrants living in South Korea into jobs and society, the main characteristics of the social enterprise scheme set up in South Korea, and a few examples of social enterprises engaged in NKs migrants’ work integration. It stresses that the process of integrating NK migrants through the social enterprise model leads to apprehend this question, not in the traditional framework of policies specific to NK migrants, but in a broader framework to address a more comprehensive issue of the integration of vulnerable populations. This is an orientation that breaks with the previous public-policy framework towards NK migrants without real counterpart benefits. This approach also supplements governmental policies that have been developed since 2005 to encourage NK migrants to engage in skills training and support programmes in employment coaching. By adding case studies that assess the effectiveness of NK migrants’ work integration based on the criteria of job creation, job skills enhancement, and normal job sustenance, this study examines whether the European-originated work integration social enterprise model works for a particular social enterprise type benefiting NK migrants in South Korea.     

Connecting smallholders with dynamic markets: a market information service in Zambia

Commodity markets have changed significantly in the past two decades, with smallholders increasingly requiring robust market intelligence to understand and secure benefit from the new environment. This article explores the approach to, and lessons stemming from, an IFAD-financed market information service in Zambia. It finds that by locating the service within a pre-existing institution with legitimacy and credibility, the service has secured the interest of a wide range of actors, and has better enabled smallholders and traders to access and utilise relevant, up-to-date, and actionable information to shape decision-making. The article concludes by discussing the key considerations that shaped the institutional analysis, and the issues that will influence the financial sustainability of the service.
