Myocardial hypertrophy induces carotid body hyperplasia

The carotid bodies tend to enlarge after long-standing cardiopulmonary disease. Our objective was to investigate whether cardiac hypertrophy is associated with carotid body hyperplasia. Fifteen autopsy cases with combined left and right ventricular hypertrophy were examined and compared with two control groups (16 cases). The study involved a meticulous dissection of carotid bifurcations, thin serial sections, and morphometric analysis of carotid body volume and cell types (progenitor, dark, light, and sustentacular). There was a significant increase in sustentacular cells in all individuals with cardiac hypertrophy, which was not drug-induced, and accompanied by a similar increase in carotid body volume. Dark or light cell accumulation was detected focally and only in three instances. It appears that the generalized sustentacular cell hyperplasia is the result of long-standing hypoxia, while a superimposed focal prominence of dark or light cells may be proliferative or metaplastic in nature and attributed to short-term hypoxia.     

Understanding Culture in Kentucky's Courtrooms: An Essential Tool for Management and Long‐Range Planning

Though the “old conventional wisdom” explained delay as the product of too few resources and staff, the “new conventional wisdom” posits court efficiency is largely due to the cultural makeup of the court. Adapting the Court Culture Assessment Instrument developed by Dr. Ostrom and colleagues at the National Center for State Courts, this research study examines judicial perceptions of culture in the Kentucky Court of Justice general and family circuit court. Results indicate circuit courts are predominantly autonomous but desire to be more structured (hierarchical). In addition, bivariate analyses showed a significant, but weak, inverse relationship exists between perceptions of a predominantly hierarchical culture orientation and the presence of delay. In other words, judges who perceived their circuit to be predominantly hierarchical in nature were less likely to perceive delay as a problem.     

Economic freedom, culture, and growth

How do economic freedom and culture impact economic growth? This paper argues that culture, as measured by the World Values Surveys, and economic institutions associated with economic freedom are both independently important for economic prosperity, but the strength of their impact can be better understood only when both are included in the growth regression. Our results indicate that economic freedom is more important than culture for growth outcomes, suggesting substitutability between the two. We posit that culture is important for growth when economic freedom is absent, diminishing in significance once economic freedom is established.     

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.     

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.
