A Validation Study of the Langley et al. (2017) Decision Tree Model for Sex Estimation

Langley et al. (2017) developed a sex estimation decision tree utilizing two traditional cranial traits (glabella and mastoid) and a new trait: zygomatic extension. This study aimed to test the reliability of their zygomatic extension scoring method and validate their sex estimation method. Ordinal score data were collected from 281 male and female U.S. White and Black individuals. The five traditional cranial traits were collected from physical specimens, while zygomatic extension was scored from 3D cranial models. Intra‐ and interobserver analyses carried out on a subsample of 30 individuals indicate good agreement between zygomatic scores. The decision tree correctly sexed 71.5% of the sample, but a strong sex bias (94.2% correct for females, 49.3% correct for males) severely limits the utility of this method. The Walker (2008) and Stevenson et al. (2009) methods produced higher accuracy rates (80.8% and 82.6%, respectively), although these methods also produced sex and ancestry biases.     

Political Homophily and Collaboration in Regional Planning Networks

We study the extent of political homophily—the tendency to form connections with others who are politically similar—in local governments’ decisions to participate in an important form of intergovernmental collaboration: regional planning networks. Using data from a recent survey of California planners and government officials, we develop and test hypotheses about the factors that lead local governments to collaborate within regional planning networks. We find that local governments whose constituents are similar politically, in terms of partisanship and voting behavior, are more likely to collaborate with one another in regional planning efforts than those whose constituents are politically diverse. We conclude that political homophily reduces the transaction costs associated with institutional collective action, even in settings where we expect political considerations to be minimal.     

The Impact of Drinking Water Quality and Sanitation on Child Health: Evidence from Rural Ethiopia

This paper examines the association between stored drinking water quality and sanitation on diarrhoea incidence among under-five children in Ethiopia. Using primary household survey data and microbiological water quality testing for Escherichia coli, our results show that uncontaminated stored drinking water and safe child stool disposal are associated with decreased child diarrhoea incidences of 18 and 20 percentage points, respectively. In contrast, neighbourhood concentration of pit latrine shows an increased incidence of child diarrhoea of 16 percentage points. To protect rural children from the risk of contracting diarrhoea, improving household drinking water quality and changing people’s behaviour towards safe sanitation practices is needed.     

Cultivated,caught, and collected: defining culturally appropriate foods in Tallé, Niger

The indigenous plants and fish of Niger are incorporated into the Songhai people's daily life but are largely underemphasised in development programmes. In this paper we describe the culturally appropriate foods of Tallé, Niger. Based on information obtained from 42 participants using interviews and focus groups, we identified 11 commonly consumed fish species, 22 plant species, and nine factors that made them culturally appropriate: taste, perceived health effects, economic value, use as snacks or staple, storability, seasonal availability, use in celebrations, abundance, and cultural identity. We conclude with a discussion of how local knowledge can be incorporated into development programmes.

Cultivés, pêchés et cueillis : définir des aliments culturellement appropriés à Tallé, au Niger

Les plantes et le poisson autochtones du Niger sont incorporés dans le quotidien des Songhais, mais on ne leur accorde généralement pas une attention suffisante dans les programmes de développement. Dans cet article, nous décrivons les aliments culturellement appropriés de Tallé, au Niger. Sur la base d'informations obtenues de 42 participants à l'aide d'entretiens et de groupes de réflexion, nous avons identifié 11 espèces de poisson fréquemment consommées, 22 espèces de plantes et neuf facteurs qui les rendent culturellement appropriés : goût, effets perçus sur la santé, valeur économique, utilisation comme en-cas ou denrées de base, facilité de conservation, disponibilité saisonnière, utilisation lors de célébrations, abondance et identité culturelle. Nous concluons par une discussion sur la manière dont les connaissances locales peuvent être incorporées dans les programmes de développement.

Cultivados, cazados y recolectados: la definición de alimentos culturalmente adecuados en Tallé, Níger

Las plantas y los peces endémicos de Níger han sido incorporados a la dieta cotidiana del pueblo songhai. Sin embargo, dicha dieta recibe escasa atención de parte de los programas de desarrollo. En el presente artículo, los autores analizan aquellos alimentos culturalmente adecuados en Tallé, Níger. Apoyándose en la información recopilada entre 42 personas que participaron en entrevistas y en grupos de enfoque, los autores identificaron 11 variedades de peces consumidas con frecuencia, 22 especies de plantas, así como nueve factores que determinan que estos alimentos sean culturalmente adecuados: sabor, efectos percibidos en la salud, valor económico de los mismos, posibilidad de uso como tentempiés o como alimentos principales, período de almacenamiento, disponibilidad estacional, uso de los mismos en celebraciones, abundancia e identidad cultural. El ensayo concluye realizando un análisis acerca de cómo los conocimientos locales pueden ser incorporados a los programas de desarrollo.

Cultivados, colhidos e coletados: definindo alimentos culturalmente apropriados em Tallé, Níger

As plantas e peixes consumidos pelos indígenas de Níger estão incorporados na vida cotidiana das pessoas de Songhai mas, geralmente, recebem pouco destaque nos programas de desenvolvimento. Neste artigo, descrevemos os alimentos culturalmente apropriados de Tallé, Níger. Com base nas informações obtidas de 42 participantes utilizando entrevistas e grupos de enfoque, identificamos 11 espécies de peixe frequentemente consumidas, 22 espécies de plantas e nove fatores que os tornam culturalmente apropriados: paladar, percepção de seus efeitos na saúde, valor econômico, uso como aperitivo ou alimento básico, armazenagem, disponibilidade sazonal, uso em comemorações, abundância e identidade cultural. Concluímos com uma discussão de como o conhecimento local pode ser incorporado em programas de desenvolvimento.     

Criminality and Armed Groups: A Comparative Study of FARC and Paramilitary Groups in Colombia

Terrorist groups and armed insurgents regularly exploit illicit markets to launder money, traffic illegal goods, and purchase arms. In such an environment, the line between armed political organizations and criminal groups appears to break down. However, through a comparative study of paramilitary groups and Fuerzas Armadas Revolucionarias de Colombia (Revolutionary Armed Forces of Colombia—FARC) in Colombia, this article finds that group goals, the political environment, and membership strongly influence the types of criminal activities a given armed groups undertakes. Thus, the membership and political agenda of sub-state armed groups not only distinguishes them from criminal groups—organized for and motivated by economic gain—but also shapes their criminal behavior.     

Security Through Sociology: The North Caucasus and the Global Counterinsurgency Paradigm

The global counterinsurgency strategy to combat terrorism emphasizes responding to the social and economic needs of communities where terrorists may find support. Public opinion data can help in that strategy, as shown by a 2006 survey of 1,200 young males from three provinces in Russia's North Caucasus. Conventional wisdom notwithstanding, the survey shows few signs of burgeoning radical Islam or ethnic animosity. Instead, economic conditions and poor governance are primary concerns. The region provides both an opportunity and threat: policymakers can and should address the region's needs; if not, radical Islamist groups can turn it into a flashpoint for terrorism.     

Student perceptions of hate crimes

Estimates indicate hate crimes are a growing concern in the United States. This paper addresses how criminal justice students perceive victims of hate crimes. Survey findings show subjects are less likely to define certain groups of people as victims of hate crimes. Suggestions are made as to how criminal justice departments can heighten awareness of hate crime victims, multiculturalism, and gender diversity among criminal justice students.
