The gamma half-Cauchy distribution: Properties and applications

A new distribution, namely, the Gamma-Half-Cauchy distribution is proposed. Various properties of the Gamma-Half-Cauchy distribution are studied in detail such as limiting behavior, moments, mean deviations and Shannon entropy. The model parameters are estimated by the method of maximum likelihood and the observed information matrix is obtained. Two data sets are used to illustrate the applications of Gamma-Half-Cauchy distribution

Understanding youth well-being in the family context: the role of democracy, warmth, and disclosure

ABSTRACTThis study applies a nonexperimental quantitative design to investigate youth well-being within the family context. Structural equation model analyses of information from 1883 seventh grade youths revealed: Democratic parenting (β = 0.43, p  .05). Future well-being research should consider parent–youth relationships, and youths could be involved in family policy-making and fostering supportive family environments

Improving Guidelines of Practice for the Prevention and Response of Suicidality in Post-Secondary Institutions

ABSTRACT: Suicide on post-secondary campuses is a pressing concern, with many students in Canada demanding that post-secondary institutions improve their policies and procedures for supporting students with suicidality. The past decade has shown an increase in research and literature on students with mental health illnesses including depression and anxiety, while research specifically on the prevention of and response to suicide at post-secondary institutions is lacking. This article expands upon current literature on suicidality in post-secondary institutions and provides recommendations including further areas of research, addressing risk factors, promoting educational awareness, and increasing help-seeking behaviour to future researchers and post-secondary professionals seeking to improve guidelines for practice in supporting students experiencing suicidality.Résumé: Le sujet du suicide sur les campus postsecondaires est une préoccupation urgente. Beaucoup d’étudiants au Canada exigent que les écoles postsecondaires améliorent leurs politiques et procédures pour mieux soutenir les étudiants suicidaires. Les recherches de la dernière décennie ont montré une augmentation des études et de la littérature sur les étudiants souffrant de maladies mentales, y compris la dépression et l’anxiété. Toutefois, la recherche spécifique sur la prévention et la réponse au suicide dans les établissements postsecondaires manquent. Cet article fournit des recommandations sur d’autres domaines d’aide au suicide tels que la lutte contre les facteurs de risque, la promotion des programmes de sensibilisation et la recherche d’aide auprès des futurs chercheurs et professionnels de l’enseignement postsecondaire afin d’améliorer les lignes directrices pour la prévention du suicide chez les étudiants

Exploring global identity in emerging adults

Recent literature has suggested that global identity and world citizenship are relevant capacities in an increasingly globalizing world. However, these concepts remain understudied. The current study aimed to explore qualities of these concepts with emerging adults and to examine their views of humanity and how these influence their decision-making. Interviews with 20 participants between the ages of 19-25 and a thematic analysis resulted in the identification of a number of themes. Global identity and citizenship, universally intrinsic, implicate global belongingness and stand as opposites to adversarial constructs. Humans, linked as one species sharing common skills, were recognized as essentially interdependent. Participants also depicted a sense of global responsibility and role unawareness in relation to humanity. The findings may serve as a springboard for a future scale development to measure these concepts

Youth well-being within the family context : Belief and behavior patterns of Swedish fathers, mothers, and youths

Youth well-being is multifaceted, complex, and embedded in sociocultural contexts. In this dissertation, youth well-being is explored within the family context from a developmental niche theoretical perspective. Belief and behavior patterns of Swedish fathers, mothers, and youths are analyzed separately based on self-reported surveys in three empirical studies. All participants are from the national research project KUPOL. In Study 1, fathers’ dominant belief patterns about youth well-being are explored. By studying 201 fathers’ descriptions, four broad and frequent themes were identified. They were cognitive, emotional/psychological, physical, and social well-being. While some sub-themes confirm earlier research findings, other sub-themes that have not received much theoretical attention were also identified. In light of these findings, youth well-being is discussed as a concept that is multidimensional and sociocultural. The study is one of the first of its kind to highlight specifically fathers’ belief patterns concerning youth well-being. In Study 2, Swedish mothers’ belief patterns of youth well-being are analyzed qualitatively, and potential links with gender and education characteristics are studied quantitatively. Based on descriptions from 1074 mothers, five dominant themes were identified, namely academic/cognitive, emotional/psychological, physical, recreational, and social well-being. Theme combinations were also identified from individual reports, with an emphasis on cognitive, emotional, and social well-being domains. The themes were not found to be linked with youths’ gender. However, mothers with higher formal education reported a greater range of belief patterns than mothers with less formal education. These findings support the sparse but existing research on mothers’ views of youth well-being. Considering that some belief patterns were more evident than others, future research should consider to what extent this might be linked with ideas and norms in the cultural and socioeconomic contexts. In Study 3, youth reports of the parent-youth relationship are studied in relation to self-evaluations of well-being. By analyzing information from 1883 youths, it was found that democratic parenting, maternal warmth, and paternal warmth were concurrently linked with youth disclosure in seventh grade, and youth disclosure was in turn associated with academic, emotional, and social well-being in eighth grade. Paternal warmth was also linked to emotional well-being a year later. Gender moderation was identified between youth disclosure and emotional well-being. The study highlights the importance of studying the family context characterized by democracy, warmth, and routine disclosure in relation to youth well-being. Beyond the findings in the three studies, the dissertation contributes to contemporary but limited knowledge on youth well-being. In conclusion, the dissertation shows how youth well-being is conceptualized by parents, what sociodemographic characteristics may be linked with these conceptual beliefs, and how mutuality between parents and youths may facilitate understanding about the complexities of youth well-being within the family context. Theoretical argumentations are proposed for the embeddedness of youth well-being in sociocultural contexts. Based on findings and theoretical underpinnings, the dissertation concludes with a discussion, practical implications, and future directions for theory and research

Teaching Semantic Prosody of English Verbs through the DDL Approach and its Effect on Learners' Vocabulary Choice Appropriateness in a Persian EFL Context

This study examined teaching SP of English verbs through the data-driven learning (DDL) approach and its effect on learners' vocabulary choice appropriateness in the Persian English foreign language (EFL) context. In the present study, two male intact classes were selected. One of these two classes was randomly selected as a treatment group and another one as a control group. The treatment group was provided with SP instruction through the DDL approach. The control group was exposed to SP as well, but traditionally and not through a DDL approach. The corpora used in the DDL approach were the Brown corpus and British National Corpus (BNC). Pretests and posttests of vocabulary choice appropriateness were administered and a repeated-measures ANOVA was used to compare means of test scores within and between subjects. The results indicated that SP instruction through DDL was significantly an effective approach to improve EFL learners' vocabulary choice appropriateness

Effects of Organic Acids Treatments with or without Ultra-Sonic Treatment on Increasing the Shelf Life of Fresh Cut Kiwifruit

The market sales of ready to use fresh cut fruits have grown rapidly in recent decades. Kiwi fruit is an important fruit that its marketing as fresh cut has increased in recent years. The main limiting factors in shelf life of fresh cut fruits are microbial spoilage, drastic softening and browning. In this study, the effects of oxalic and citric acids, both at 0, 2, 4 and 6 mM concentrations, with or without ultra-sonic treatment were investigated on the increasing the shelf life of fresh cut kiwi fruit. After treatments, the fresh slices were stored at 2°C for 7 or 14 days and assessed for several traits and analyzed. Results showed that, oxalic and citric acid treated slices, in comparison to the control, had greater marketability, as well as higher flesh firmness, titrable acidity, ascorbic acid content, total phenol content and antioxidant capacity and smaller bacterial forming colony unit (CFU). Among the treatments, 2, 4 and 6 mM oxalic acid and 6 mM citric acid treatments were found more appropriate than the reaming treatments. Application of ultra-sonic treatment, despite the reduction of microbial load and maintaining antioxidant capacity, had no effects on marketability of fresh cut kiwi fruit. Hence, application of organic acid treatments as dipping can be used to increase the shelf life of fresh cut kiwi fruit
