The variation in the epidermal ridge's width between the sexes, during various growth stages, and among different populations has been previously assessed. However, the changes that occur with aging are barely known.The goal of this study was to analyse the degree of variation in epidermal ridge width due to aging. So that, fingerprint ridge density was estimated to establish their relationship with body and hand size changes that typically occur in adulthood.In this study, a sample of 213 adults of both sexes from a Spanish native population of different age ranges—18–30?years old (“junior” group) and 50–66?years old (“senior” group)—was used. Ridge density was assessed in three counting areas of the distal phalanx of each finger (radial, ulnar, and proximal). Height, weight, and a set of anthropometric measurements for both hands were also taken.Our results show that ridge density is higher in females than males throughout adulthood and decreases with aging in the radial and ulnar areas (as the hands widen) but not in the proximal region. Thus, a relationship between hand dimensions and ridge density was found.The data indicate that aging changes may conceal the recognized sex differences in ridge density, and so a better understanding of the topological variations in the epidermal ridge width throughout the life cycle and the factors involved would facilitate the interpretation of the differences between the sexes and different age groups. 相似文献

Since the beginning of the twenty-first century, expansion of the formal credit supply in Brazil has promoted the ‘financial inclusion’ of the low-income population, especially through instalment plans offered by large retail chains. This article aims to analyse the impacts of formal credit availability on the consumption of electrical and electronic goods by residents of Jardim Helena, a neighbourhood in São Paulo's periphery. Through the collection and analysis of qualitative and quantitative data, this study reveals how the instalment plan can stimulate consumption among the low-income population, with a significant impact on household budgets, raising the risk of indebtedness. 相似文献

We explore the strategies implemented by Research Groups' Leaders while coping with unstable contexts, characterized by incoherence and lack of coordination among different policy discourses and instruments, and scarce resources. We focus on a country where these conditions are present: Colombia. In doing so, we study two cases, one in nanotechnology and another one in biomedical engineering. Interviews, focus groups and workshops allowed us to identify and validate strategies grouped in four popular sayings, proper to local idiosyncrasy, highlighting the role of home institutions and principal investigators in facing such situations with resilience and resourcefulness, and even taking advantage of them. We find that Research Groups' Leaders use strategies such as: adapting, balancing agendas and funding sources, networking, and taking advantage of the support programs available at their home institution to continue functioning. These are setting the ground for a further survey which could pretend some generalization. However, policymakers could consider these findings when defining policy instruments or for assessing their effectiveness or impacts. 相似文献

Interior immigration enforcement in the U.S. has rapidly increased over the past two decades, including increased Immigration and Customs Enforcement (ICE) activity and the revival of workplace raids under the Trump administration. We contribute to the body of research that aims to better understand the consequences of immigration enforcement for children in targeted communities, including on their education, health, and socioemotional well-being. We employ a mixed methods research design to investigate the effects of the sweeping April 2018 Morristown, Tennessee immigration raid on children's health and education outcomes. We utilize linked, longitudinal health and education data on children and a quasi-experimental design to analyze the effects of the raid on those residing in close proximity to the raid. Interview data from community members and organizations in the affected area aid in better understanding how the raid unfolded and the mechanisms through which a community trauma such as this might affect children both directly and indirectly. Our results indicate negative effects across multiple education and behavioral health outcomes for children of immigrants living in the area targeted by the raid, including a substantial spike in absences from school in the month of the raid and significant increases in exclusionary disciplinary actions and in diagnoses of substance use disorder, depression, self-harm, suicide attempts or ideation, and sexual abuse in the year following the raid. 相似文献
