Sex Assessment from the Sacral Base by Means of Image Processing

Abstract:  To help improve sex assessment from skeletal remains, the present study considers the diagnostic value of the sacral base (basis osseus sacri) based on its planar image and related metric data. For this purpose, 114 adult sacra of known sex and age from two early 20th century Italian populations were examined, the first from Bologna, northern Italy ( n  = 76), and the second from Sassari, Sardinia ( n  = 38). Digital photos of the sacral base were taken with each bone in a standardized orientation. Technical drawing software was used to trace its profile and to measure related dimensions (area, perimeter, and breadth of S1 and total breadth of the sacrum). The measurements were subjected to discriminant and classification function analyses. The sex prediction success of 93.2% for the Bolognese sample, 81.6% for the Sassarese sample, and 88.3% for the pooled sample indicates that the first sacral vertebra is a good character for sex determination.     

Der Billigkeitsbegriff im nachehelichen Unterhaltsrecht

Im ?sterreichischen Ehegesetz stellt der Gesetzgeber zur Regelung des nachehelichen Unterhalts in den §§ 67 ff EheG auf den Begriff der Billigkeit ab, um bestm?gliche Einzelfallgerechtigkeit zu gew?hrleisten. Die inhaltliche Ausgestaltung dieses unbestimmten Gesetzesbegriffes ist aber durchaus unterschiedlich. Der vorliegende Beitrag versucht in einer vergleichenden Gegenüberstellung unter Berücksichtigung des Schrifttums und der Judikatur die unterschiedlichen Bedeutungen des Billigkeitsbegriffs im nachehelichen Unterhaltsrecht aufzuzeigen.     

Direct and non-linear innovation effects of demographic shifts

A varied set of pressures drive organizational innovation. Among these pressures, demographic shifts seem to boost innovation, as the public sector responds to the arrival of migrants and to community changes in race and ethnic composition. However, we know little about innovation by governments in response to expected population decline. In particular, studies have under-examined how anticipated demographic pressures prompt public organizations to innovate. This study undertakes this task by arguing that innovation is more visible in municipalities facing greater anticipated demographic decline. However, we also argue for a non-linear relationship in which too strong and/or too weak expected demographic declines lead to less visible innovation (inverted U-shape effect). These propositions were tested with a data set of Japanese municipalities and employing a dose–response model. Findings show that anticipated demographic declines directly boost innovation visibility. However, too strong and/or too weak unexpected demographic declines make innovation less visible.     

“The Good,the Bad and the Ugly” Reconsidered: A Comparison of German,Canadian and Spanish Labour Migration Policies

This article compares three immigration countries that are perceived, both publicly and politically, as being fundamentally different: Canada, which is allegedly one of the most attractive destination countries for labour migrants worldwide; Germany, which is still thought to be sceptical towards immigration; and finally Spain, which is considered institutionally incapable of implementing efficient labour migration policies. Against the backdrop of various political reforms that have been adopted in these countries, however, the article argues that such a distinction is becoming increasingly inaccurate. This observation is backed empirically by analysing the technique of screening labour migrants and the temporal design of labour migration policy.     

What Drives Japanese INGOs to Operate in Latin American Countries?

International nongovernmental organizations (INGOs) provide essential aid and public services to less-developed countries. Although most literature focuses on Western INGOs, Asian INGOs have also become globally active. Little is known about what motivates INGOs to provide services in other regions, such as Latin America. In this study, we seek to identify the criteria Japanese INGOs use to select Latin American recipient countries. We propose that Japanese INGO operational location decisions are a function of Japanese foreign policy agenda, Japan-recipient country business relations, and recipient country’s need and liberalization. Using data from Japanese INGOs working in Latin America and 24 Latin American countries on contextual, macroeconomic, and demographic indicators, we find that the significant factors driving INGO decisions to operate in Latin American countries are need and the presence of Japanese businesses in the recipient country. Results have practical implications for foreign aid targeting and economic development.     

The influence of sense of coherence,self-care and work satisfaction on secondary traumatic stress and burnout among child and youth residential care workers in Switzerland

The present study aimed to investigate the incidence of post-traumatic and secondary traumatic stress as well as burnout symptoms among child and youth welfare workers in residential care in Switzerland and to assess the predictive value of sense of coherence, self-care, and job satisfaction. A sample of 319 child welfare professionals in Swiss child and youth residential care was assessed using questionnaires that addressed sense of coherence, perceived collective efficacy, self-care, and work satisfaction, as well as symptoms of traumatic stress and burnout. Linear regression analyses were conducted to determine the influence of sense of coherence, self-care and job satisfaction on symptoms of burnout and traumatic stress. Enhancing sense of coherence, work-related self-care and work satisfaction could reduce stress symptoms and increase the well-being of child and youth welfare staff. The authors discuss how child and youth residential care institutions could improve these factors among their staff.     

Evaluating Transport Infrastructure Projects in Low Data Environments: An Application to Nigeria

Transport infrastructure consumes a large fraction of the development assistance envelope. Yet procedures for evaluating transport infrastructure projects are typically ad-hoc. This paper proposes an approach to assess the differential impacts of alternative investment proposals in data constrained environments where conducting reliable impact analyses is difficult. We first demonstrate a technique for estimating the cost of transporting products to markets. We then estimate the impact of improving the road network on economic activity. Finally, we perform simulations to demonstrate a methodology for prioritising alternative investments. The analysis demonstrates a pragmatic, though rigorous, approach for assessing transport infrastructure benefits.
