A surplus process involving a compound Poisson counting process and applications

Abstract

In this paper, we introduce a surplus process involving a compound Poisson counting process, which is a generalization of the classical ruin model where the claim-counting process is a homogeneous Poisson process. The incentive is to model batch arrival of claims using a counting process that is based on a compound distribution. This reduces the difficulty of modeling claim amounts and is consistent with industrial data. Recursive formula, some properties and relevant main ruin theory results are provided. Further, we consider applications involving zero-truncated negative binomial and zero-truncated binomial batch arrivals when the claim amounts follow exponential or Erlang distribution.     

Terms of engagement: Facebook and Twitter use among nonprofit human service organizations

This study uses Lovejoy and Saxton's (2012) hierarchy of engagement to analyze how nonprofit human service organizations use Facebook and Twitter to engage stakeholders. Their framework has not been applied to this nonprofit subgroup, and most previous scholarship on this topic focuses on just one platform. We also contribute by drawing on organizational theory to better understand variation in the modes of engagement organizations emphasize. Based on our analysis, we add new subcategories to the hierarchy of engagement. In addition, we find that compared to other nonprofit subgroups examined in previous research, the organizations in our sample placed a greater emphasis on using social media messages to ask stakeholders to take action. We report only modest variations in how organizations were using Facebook and Twitter. Finally, according to our results, resource dependence and stewardship theories help explain the modes of engagement organizations prioritize.     

Toward Father‐friendly Parenting Interventions: A Qualitative Study

Levels of father participation in parenting interventions are often very low, yet little is known about the factors which influence father engagement. We aimed to qualitatively explore perceived barriers to, and preferences for, parenting interventions in a community sample of fathers. Forty‐one fathers across nine focus groups were interviewed using a semi‐structured interview. Data were analysed using inductive thematic analysis. Key barriers to father participation identified included: the perception that interventions are mother‐focused; beliefs about gender roles regarding parenting and help‐seeking; mothers’ role as ‘gatekeeper’; lack of knowledge and awareness of parenting interventions; and lack of relevance of interventions. Fathers reported preferences for specific content and intervention features, facilitator characteristics, practical factors, and highlighted the need for father‐targeted recruitment and advertising. Many of the barriers and preferences identified are consistent with previous research; however, fathers’ beliefs and attitudes around gender roles and help‐seeking, as well as the perception that interventions are predominantly mother‐focused, may be key barriers for community fathers. Strategies to overcome these barriers and better meet the needs of fathers in promoting and delivering parenting interventions are discussed.     

The impact of testosterone replacement therapy on glycemic control,vascular function,and components of the metabolic syndrome in obese hypogonadal men with type 2 diabetes

Objective: This study set out to assess effects of testosterone replacement therapy (TRT) on parameters of metabolic syndrome and vascular function in obese hypogonadal males with type 2 diabetes mellitus (DM2).

Study design: Fifty-five obese hypogonadal diabetic males on oral hypoglycemic treatment were enrolled into this one-year, double-blind, randomized, placebo-controlled clinical study. Group T (n?=?28) was treated with testosterone undecanoate (1000?mg i.m. every 10?weeks) while group P (n?=?27) received placebo.

Methods: Anthropometrical and vascular measurements – flow-mediated dilatation (FMD) and intima media thickness (IMT) – biochemical and hormonal blood sample analyses were performed at the start of the study and after one year. Derived parameters (BMI, HOMA-IR, calculated free testosterone (cFT) and bioavailable testosterone (BT)) were calculated.

Results: TRT resulted in reduction of HOMA-IR by 4.64?±?4.25 (p?p?p?=?.005).

Conclusion: TRT normalized serum testosterone levels, improved glycemic control and endothelial function while exerting no ill effects on the study population.     

Confrontations and donations: encounters between homeless pet owners and the public

This study examines the interactions between homeless pet owners and the domiciled public with a focus on how the activities of pet ownership help construct positive personal identities. Homeless people are often criticized for having pets. They counter these attacks using open and contained responses to stigmatization. More often, they redefine pet ownership to incorporate how they provide for their animals, challenging definitions that require a physical home. Homeless pet owners thus create a positive moral identity by emphasizing that they feed their animals first and give them freedom that the pets of the domiciled lack. Through what we call “enabled resistance,” donations of pet food from the supportive public provide the resources to minimize the impact of stigmatization.     

Maternal narration about parenting pride and regret is related to youth emotion regulation

As they respond to children's emotions, mothers socialize children's emerging emotion regulation. Mothers' own autobiographical narratives likely reflect in part habitual ways of expressing and managing emotions—ways that may in turn influence the way mothers respond to their children's emotions. We examined features of mothers' narratives about parental pride and regret experiences, and assessed whether these were associated with parental socialization of emotion and the emotion regulation repertoire of their children. Two hundred thirty‐seven mothers with children ranging from 8 to 17 years of age provided two narratives about parental pride and parental regret experiences. Parental emotion socialization and children's emotion regulation were assessed via self‐ and informant‐report using a multi‐measure, multi‐observer approach. We found that features of the way mothers narrated their experiences with a particular child related to their parenting of that child, and that child's emotion regulation. The findings are discussed in terms of their implications for emotion‐related parenting, and the potential importance of parent narratives.     

An integrative intervention for promoting recovery from extramarital affairs

The discovery or disclosure of an extramarital affair can have a devastating impact on partners, both individually and on the relationships. Research suggests that affairs occur relatively frequently in relationships and are a common presenting problem in couple therapy. However, despite their prevalence, there is little empirical treatment research in this area, and most therapists describe this problem as one of the more difficult to treat. In this study, we used a replicated case-study design to explore the efficacy of an integrative treatment designed to help couples recover from an affair. Six couples entered and completed treatment. The majority of these couples were less emotionally or maritally distressed at the end of treatment, and the injured partners reported greater forgiveness regarding the affair. Details of the intervention, suggested adaptations of the treatment, and areas for future research are discussed.
