Identifying Southwest Hispanics using nonmetric traits and the cultural profile

Due to the increasing number of Southwest Hispanics in the United States, as well as the overwhelming number of foreign nationals that die every year trying to enter the United States along the southern United States border with Mexico, new methods for classifying individuals have been established at the Pima County Office of the Medical Examiner in Tucson, Arizona (PCOME). For each of the past 5 years, the PCOME has investigated a record number of deaths associated with these border crossings. The overwhelming majority of the identified decedents are Mexican Nationals. However, approximately 25% of these undocumented border crossers have yet to be identified, making it clear that improved methods for human identification are greatly needed. The first goal of this paper is to delineate the suite of skeletal nonmetric traits utilized in assessing Southwest Hispanic ancestry at the PCOME. This suite of nonmetric traits has proven to be an effective component in establishing the "biological profile" of unknown individuals in these cases. The second goal of this paper is to introduce methods used at the PCOME to establish the "cultural profile" of individuals in these cases. The "cultural profile" is a set of identification criteria that include: the geographic context of recovery, personal effects, dental health, and cultural accoutrements. Establishing the "cultural profile" in these cases is essential in identifying individuals as foreign nationals who have died trying to cross the border.     

隐私关注对移动个性化服务采纳的影响——基于用户主观认知视角的实证研究

文章研究隐私关注与MPS采纳行为意愿之间的影响关系,创新性提出从用户主观认知视角的MPS采纳理论模型。通过调研收集421份问卷,并采用结构方程模型进行隐私关注程度测量与用户隐私认知之间关系分析,验证各影响因素与隐私关注,以及隐私关注与采纳MPS意愿之间的理论假设。结果表明,用户隐私倾向、内控点、社交群体对隐私关注信息收集、错误使用、不正当访问、二次使用都有显著的正向影响;用户开放性、随和性和外向性对隐私关注上述四个维度都有显著的负向影响;同时,提出的影响因素通过隐私关注四个维度均负向影响用户采纳MPS的意愿。文章能为企业革新隐私关注下的网络营销方式,以及促进用户采纳MPS意愿向实际行为转换提供理论支持。     

Metric Assessment of the Pubic Bone Using Known and Novel Data Points for Sex Estimation,

Biological sex estimation of skeletal remains is essential in forensic and archaeological analyses. Anthropologists most often use the pelvis, which is the most sexually dimorphic element both morphologically and metrically. While nonmetric pubic bone features have been studied extensively, few metric studies have examined this individual bone for dimorphism. For this study, three observers examined three previously identified and ten novel measurements of the pubic body on a modern sample of isolated pubic bones from the Maricopa County Forensic Science Center (FSC), in Phoenix, Arizona (n = 400). A relationship between pubic body measurements and biological sex was demonstrated, with significant correlations. Discriminant function analyses found that five measurements, four of which were novel, discriminated between males (89%) and females (86%). Observer experience level did not significantly impact the results. These five measurements were reliable and show promise for inclusion in metric methods for assessment of sex.     

Personality traits of convicted male batterers

The purpose of this investigation is to determine if select psychological variables are associated with abusive behavior of convicted male batterers. The sample included a treatment group of 75 court-referred abusers who were individually administered the Taylor-Johnson Temperament Analysis (T-JTA) instrument. Explored were: (1) the relationships among personality variables and sociological and demographic characteristics, (2) possible behavioral disorders in our study group of spouse abusers, (3) whether major bipolar personality variables could distinguish our study group from the general population. Results revealed the Taylor-Johnson behavioral disorder types were not useful in identifying distinctions among our spouse abusers. However, a two-factor rotation (Internal/Emotional Balance and Social Interaction) produced results which should be of interest to programs treating batterers as well as provide a suggestive lead for future research. Battering men were found to have a restless proclivity for interaction that will be competitive and conflict-oriented in style. Their impulsiveness further suggests that their interactions will be negative in terms of evocation.     

Perceptions of police-juvenile contact predicts self-reported offending in adolescent males

ABSTRACT

Evidence suggests that positive experiences with the police can foster attitudes of respect towards the justice system that can reduce an adolescents’ propensity to commit later illegal behaviors. To advance prior work, we tested whether this association might be stronger for those adolescents who associate with deviant peers. Additionally, we tested whether the link between attitudes towards police and the justice system, and the influence of peer delinquency, would be weaker for those with elevated callous–unemotional (CU) traits. These predictions were examined in a prospective study using a sample (N?=?1,216) of adolescent males who were followed prospectively for 2 years following their first official contact with the juvenile justice system. Positive experiences with the police following the youth’s first arrest were associated with less self-reported delinquency 2 years later, which was partially mediated by reductions in adolescents’ cynicism about the legal system. However, this link was only significant for youth with low levels of peer delinquency. Although CU traits were related to less positive perceptions of experiences with the police and greater cynicism about the justice system, CU traits did not moderate the associations among experiences, attitudes, and later illegal behavior nor did they moderate the influence of peer delinquency.

Statistical Classification Methods for Estimating Ancestry Using Morphoscopic Traits,

Ancestry assessments using cranial morphoscopic traits currently rely on subjective trait lists and observer experience rather than empirical support. The trait list approach, which is untested, unverified, and in many respects unrefined, is relied upon because of tradition and subjective experience. Our objective was to examine the utility of frequently cited morphoscopic traits and to explore eleven appropriate and novel methods for classifying an unknown cranium into one of several reference groups. Based on these results, artificial neural networks (aNNs), OSSA, support vector machines, and random forest models showed mean classification accuracies of at least 85%. The aNNs had the highest overall classification rate (87.8%), and random forests show the smallest difference between the highest (90.4%) and lowest (76.5%) classification accuracies. The results of this research demonstrate that morphoscopic traits can be successfully used to assess ancestry without relying only on the experience of the observer.     

Psychological and behavioral adjustment in female youths with high or low psychopathic traits

The aim of the present study was to analyze the role of psychopathic traits in female juvenile delinquency. Using a sample of 236 young females from the Juvenile Detention Centers of the Portuguese Ministry of Justice and schools in the Lisbon area, a group of female youths with high psychopathic traits (n = 118; M = 15.84 years of age; range = 14–18 years of age) and a group of female youths with low psychopathic traits (n = 118; M = 15.77 years of age; range = 14–18 years of age) were formed based on the Portuguese version of the Antisocial Process Screening Device-Self-report (APSD-SR). The results showed that young females with high psychopathic traits start engaging in criminal activities and come into contact with the justice system earlier in life; exhibit higher levels of behavioral problems, conduct disorder, delinquent behaviors and serious criminality; and demonstrate lower levels of self-esteem and pro-social behavior. The importance of some variables in predicting group membership (high versus low psychopathic traits) was established through a binary logistic regression. Our findings reinforce the importance of the psychopathy construct for the early identification of potentially high-risk female youths and for the assessment of female youths who have already come into contact with the judicial system.
