Critical Hopefulness Among Urban High School Students

Psychological empowerment encompasses several key aspects of youth civic and sociopolitical development. Most research has focused on psychological empowerment’s emotional component, which entails learned hopefulness about one’s own ability to participate in and lead community change efforts. Fewer studies have assessed critical awareness of how social power operates—psychological empowerment’s cognitive component. The confluence of these two components has been termed critical hopefulness. A complex relationship exists between these two components, and previous research has found relatively small proportions of participants reporting both high levels of critical awareness and simultaneously high levels of hopefulness about their ability to exert influence in the sociopolitical domain. The current study of urban high school students in the Northeastern U.S. (n?=?389; 53.5% female) investigates heterogeneity according to these two components of psychological empowerment. Latent class cluster analyses were conducted and seven distinct groups of participants emerged. Students identifying as Hispanic/Latinx were more likely to be classified into a profile group exhibiting critical hopefulness. Differences were observed between psychological empowerment profile groups on self-reported levels of psychological sense of community, civic engagement, and social justice orientation. Furthermore, a larger proportion of this overall sample was classified into groups that exhibited critical hopefulness than in a previous study of adults. These findings provide useful insights for efforts to engage young people in civic life and to promote sociopolitical development.     

Eliminating ill-founded eliminations in handwriting comparison cases.

Document examiners sometimes eliminate writers on the basis of differences which are given too much weight. This article is an attempt to explain some conditions whereby differences in the writing of one individual are misinterpreted as significant differences, when they are actually caused by conditions which are unknown to the examiner.     

Postmortem changes in the level of calcium pumping adenosine triphosphatase in rat heart sarcoplasmic reticulum

The activity of calcium pumping adenosine triphosphatase (Ca2+-ATPase) in cardiac sarcoplasmic reticulum plays a pivotal role in myocardiac contraction-relaxation. The Ca2+-ATPase activity is controlled by phosphorylation and dephosphorylation of a sarcoplasmic reticulum protein "phospholamban" in response to neurotransmitters and drugs. To clarify the role of Ca2+-ATPase in the development of cardiac rigor mortis, we examined the changes of cardiac rigidity and cardiac sarcoplasmic reticulum Ca2+-ATPase activity up to 5 h after the decapitation of rats. Fifteen minutes after decapitation, the rats showed a cardiac rigidity on left ventricles. After 30 min, rigidity was obvious over the whole heart. After 1 h, the rigidity reached a high degree which was maintained for the rest of the observation period. On the other hand, the Ca2+-ATPase activity controlled by phosphorylation and dephosphorylation of phospholamban did not change for the whole observation period (5 h). Another Ca2+-ATPase activity representing the total amount of Ca2+-ATPase in sarcoplasmic reticulum gradually decreased. The data suggest that no significant phosphorylation or dephosphorylation of phospholamban occurs for a short time, at least for 5 h, after death and that the Ca2+-ATPase tends to relax the myocardium against the development of cardiac rigor mortis.     

The morphogenesis of electrically and heat-induced dermal changes in pig skin

In order to establish pathological evidence in dermis for distinguishing between sequelae of electrical torture and those of other superficial injuries, the skin of eleven fully anaesthetized Danish Landrace pigs have been exposed to heat and electrical energy from either 50 Hz alternating current (a.c.) or direct current (d.c.) via 12 mm large contact knobs or via a pointed 0.5 mm large electrode (only 50 Hz a.c.). The lesions have been examined from 1 to 126 days after the injury. While heat lesions exposed to energy lower than 60 joule only gave minor changes, heat lesions exposed to more than 60 joule showed changes in both collagen fibres (basophilic or eosinophilic fibres without any birefringence or coarse cross-striation in polarized light, respectively) and dermal cells (granular cytoplasm). Areas exposed to 50 Hz a.c. via 0.5 mm. electrode showed basophilic collagen fibres and in a few biopsies on day 7 calcium salts on collagen fibres. Using 12 mm large electrodes the changes were minor, but basophilic and eosinophilic collagen fibres with no birefringence or with fine/coarse cross-striation respectively were seen. Even cells with 'vesicular nuclei' were seen on day 1 and 2 after the injury. The changes in the anode area showed resemblance to that of heat lesions (basophilic collagen fibres). Eosinophilic collagen fibres with fine densely spaced cross-striation in polarized light and 'vesicular nuclei' as well as collagen fibres with calcium salts were seen in the cathode lesions. It is concluded that the dermal changes in the cathode area are specific for electrical injury from day 1 to 14. However, earlier studies have demonstrated dermal changes specific for electrical injury at day 0 and the presence of calcified collagen fibres up to 2 months after injury. The dermal changes in anode lesions were non specific and could not be differentiated from those found in heat lesions. Alternating current lesions (50 Hz) were specific from day 1 to day 7, when the pointed electrode was used, but only in a few days when the energy was transferred via the 12-mm electrodes.     

An Examination of Reciprocal Associations Between Social Preference,Popularity, and Friendship during Early Adolescence

Getting along with peers becomes increasingly important to health and well-being during early adolescence (10–14 years). Young adolescents may succeed with peers when they are well-liked by and popular among the larger peer group (or at the group-level of social complexity). They might also fare well with peers when they are able to form numerous mutual and high quality friendships (at the dyadic-level of social complexity). Theory emphasizes the interrelatedness of different types of peer experiences, but few longitudinal studies have examined the interplay among and between group- and dyadic-level peer experiences in the same study. As a result, it is not known whether group-level peer experiences are predictors of dyadic-level peer experiences, and/or vice versa. To address this limitation, this study examined the prospective and reciprocal relations between four indices of peer experiences, preference (or being highly liked and not disliked by peers), popularity (or having a reputation as popular), friendship quantity (or having many mutual friends), and friendship or relationship quality, during early adolescence. Participants were 271 adolescents (49% girls; M_age?=?11.52 years) who completed peer nominations of preference and popularity, a self-report measure of friendship quality, and nominated friends at two waves (Wave 1: November, Grade 6; Wave 2: October, Grade 7). Structural equation modeling indicated that friendship quantity predicted increases in preference and popularity and that friendship quality predicted increases in friendship quantity. Initial popularity was associated with decreases in preference. The importance of these findings for future research is discussed along with study limitations.     

Rethinking the Tunisian miracle: a party politics view

Five years on from the Tunisian revolution, Tunisia stands as the sole success story of the Arab Spring. The country since then has managed to adopt a pluralist and democratic constitution, and held three free and fair elections. Accordingly, in the eyes of several observers, Tunisia is now in the process of consolidating its new democracy. However, the reality on the ground seems much gloomier, as most recent opinion surveys suggest that there is a significant degree of dissatisfaction, not only with political parties and Parliament but also with the very institution of democracy. Nevertheless, what accounts for this change? After the collapse of the long-lasting and oppressive Ben Ali regime, how, just in five years, has Tunisians’ confidence in the democratic process changed? This article accounts for this state of affairs from a party politics view, arguing that political parties, which are the main protagonists of the consolidation process, fail to fulfill their role of acquiring legitimacy for the new regime. While party–state relations seem to be stabilized due to the inclusiveness of the constitution-making process, both inter-party relationships and the relationship between parties and society suffer from numerous flaws which, in turn, hamper the democratic consolidation process.     

Understanding the Influence of Mental Health Diagnosis and Gender on Placement Decisions for Justice-Involved Youth

Justice-involved youth have high rates of psychiatric diagnoses, and these youth are often placed out-of-home, although evidence identifies several negative implications of juvenile confinement, especially for youth with psychopathology. Furthermore, youth in the justice system may be processed differently based on gender. As males and females tend to manifest symptoms differently, the psychopathology of youth may act to moderate the relationship between gender and placement in the juvenile justice system. The present study used a large, diverse sample (n?=?9?851, 19.8?% female) to examine whether youth placed in various types of out-of-home facilities differed in terms of externalizing, internalizing, substance use, or comorbid disorders, and to determine the predictive value of mental health diagnoses in placement decisions. The moderation effect of psychopathology and substance use on the relationship between gender and placement also was explored. The results indicated that each type of disorder differed across placements, with internalizing being most prevalent in non-secure, and externalizing, comorbid, and substance use being most prevalent in secure settings. Mental health diagnoses improved the prediction of placement in each out-of-home placement beyond legal and demographic factors such that externalizing and substance use disorders decreased the likelihood of placement in non-secure settings, and internalizing, externalizing, and substance use disorders increased the likelihood of placement in secure and state-secure facilities. The relationship between internalizing pathology and placement in more secure facilities was moderated by externalizing pathology. The relationship between gender and placement was significantly moderated by mental health such that females with mental health diagnoses receive less secure placements. Implications for policymakers and practitioners are discussed, as well as implications for reforming juvenile justice within a developmental approach.     

Comparison of Impact of Procedural Justice and Outcome on Victim Satisfaction: Evidence From Victims’ Experience With Registration of Property Crimes in India

Crime victim–police interface and registration of crime are the early and fundamental interactions in the criminal justice system. The process of lodging a complaint is marked by the pain of victimization, sharing of information, and expectation of quick remedial action from the police. The nature and quality of experience of the victim and outcomes impact the level of satisfaction with services of police. Through a survey of victims of property crimes, in different areas of a state in India, the author examines the impact of procedural justice and outcomes on victim satisfaction. The study illuminates the outcome oriented expectations of the victim, and the unique dynamics of victim–police interaction, which strains the legal ethical framework of the criminal justice system.
