Young adulthood is a period renowned for engagement in impulsive and risky behaviors, including gambling. There are some indications that young adults exhibit higher gambling rates in comparison to older adults. Problem gambling has also been linked to ADHD. This longitudinal study examines the relationship between gambling and ADHD among an epidemiological sample of young adults (n = 235; males = 179, females = 56) aged 18-24. Results indicate that individuals who report childhood ADHD symptoms which persist into young adulthood experience greater gambling problem severity than participants with no ADHD or those with non-persistent ADHD.  相似文献

The term gridlock describes the occurrence of rigid patterns in couples’ conflict. This study aimed to describe strategies of conflict resolution and gridlock prevention from the perspectives of couples and couple therapists. Participants were couple therapists and highly adjusted couples scored by the dyadic adjustment scale (DAS), distributed according to traditional and non‐traditional position in life and duration of relationships. Conflict gridlock scenarios were used to create video stimulus that were presented to participants. A qualitative methodology was used to analyse couples’ and therapists’ commentaries on the scenarios. Results showed differences in preventing conflict gridlock among sub‐groups of couples. Long‐term traditional couples focused on loyalty to a common project and value sacrificing to a higher good; long‐term non‐traditional couples prioritised caring and validating the bond in the relationship. Short‐term traditional couples focused on mutual love and the relief of hurt while short‐term non‐traditional couples supported the value of equity.  相似文献

Critical infrastructure networks enable social behavior, economic productivity, and the way of life of communities. Disruptions to these cyber–physical–social networks highlight their importance. Recent disruptions caused by natural phenomena, including Hurricanes Harvey and Irma in 2017, have particularly demonstrated the importance of functioning electric power networks. Assessing the economic impact (EI) of electricity outages after a service disruption is a challenging task, particularly when interruption costs vary by the type of electric power use (e.g., residential, commercial, industrial). In contrast with most of the literature, this work proposes an approach to spatially evaluate EIs of disruptions to particular components of the electric power network, thus enabling resilience‐based preparedness planning from economic and community perspectives. Our contribution is a mix‐method approach that combines EI evaluation, component importance analysis, and GIS visualization for decision making. We integrate geographic information systems and an economic evaluation of sporadic electric power outages to provide a tool to assist with prioritizing restoration of power in commercial areas that have the largest impact. By making use of public data describing commercial market value, gross domestic product, and electric area distribution, this article proposes a method to evaluate the EI experienced by commercial districts. A geospatial visualization is presented to observe and compare the areas that are more vulnerable in terms of EI based on the areas covered by each distribution substation. Additionally, a heat map is developed to observe the behavior of disrupted substations to determine the important component exhibiting the highest EI. The proposed resilience analytics approach is applied to analyze outages of substations in the boroughs of New York City.  相似文献

Analysing a 2 2 2 table is one of the most frequent problems in applied research (particularly in epidemiology). When the table arises from a 2 2 2 multinomial trial (or the case of double dichotomy), the appropriate test for independence is an unconditional one, like those of Barnard (1947), which, although they date from a long time ago, have not been developed (because of computational problems) until the last ten years. Among the different possible versions, the optimal (Martín Andrés & Tapia Garcia, 1999) is Barnard's original one, but the calculation time (even today) is excessive. This paper offers critical region tables for that version, which behave well compared to those of Shuster (1992). The tables are of particular use for researchers wishing to obtain significant results for very small sample sizes (N h 50).  相似文献

As many NGOs find themselves responding to the same crises, they have realized the potential benefits of coordinating their information and communication technology (ICT) activities—sharing satellite communications and internet access, sharing disaster assessment information—and have created cross-organizational coordination bodies. Coordination at the headquarters level across organizations has proven to be insufficient, and some bodies are now engaging ICT personnel in their field offices in coordination efforts. This case study presents the findings of one body’s field office coordination efforts among its ICT workers, where trust building through collaborative activities is revealed to be essential elements in successful coordination across organizations.  相似文献

Although the U.S. population is becoming more racially and ethnically diverse, research indicates that minority participation in the arts continues to decline. This article addresses the racial disparity of public art museum attendance by examining the role of the art museum curator and the process by which concepts of race are reproduced within the space of the public art museum. Utilizing Bourdieu's theories of cultural reproduction, social space, and symbolic power as a preliminary framework of inquiry, we examine the concept of whiteness as privileged social construct. Through face‐to‐face in‐depth interviews with museum curators, we investigate the means by which the dominant cultural narrative of whiteness is maintained through the preferences, decisions, and social interactions of curators. We draw upon critical white studies, a part of critical race theory, to underline the manner in which whiteness presents itself as a position of dominance. Our findings show that whiteness is maintained through the process of exclusion by presenting the white cultural narrative as both ordinary and invisible.  相似文献

The relationship between economic fluctuations and mortality is assessed with data from Spain during the years 1980–1997, when national unemployment oscillated between 7% and 24%. Mortality rates of the Spanish provinces are modeled in fixed-effect panel regressions as functions of the demographic structure and the economic conditions. Unemployment effects on general mortality, sex-specific mortality, and mortality for major causes of death are negative, i.e., death rates increase procyclically when joblessness diminishes in an economic expansion. Homicides and female suicides are only weakly related or unrelated to economic fluctuations, but male suicides escalate countercyclically during economic downturns.

This article focuses on dialogic discursive dynamics present in couples’ conversations about unresolved conflicts. The phenomenon of conflict is addressed as a semiotically mediated process of co‐construction of the self and the relationship. The purpose of this article is to report on patterns of meaning construction in couples’ conflict, with the identification of strategies that promote or hinder resolution. A qualitative exploratory approach was used to focus on the interactional process at the micro‐processing level. Eight married couples participated in the study. The procedure considered asking the couple to discuss unresolved conflict. Recorded data of couples’ dialogues were transcribed to text and assessed through semiotic analysis using a microgenetic protocol (Molina, Del Río, & Tapia, 2015). The results document the use of strategies for conflict regulation such as psychological distancing, opposition, and generalisation on the border between protecting the bond and regulating tension. The dynamics of non‐resolution manifested in polarisation and rigid patterns with increased tension. The ‘in‐motion’ nature of dialogue about conflict is pushed by the semiotic tension that induces variations in subjective positions manifested in speech and actions.  相似文献

Background

Increased circulating levels of prolactin have been associated with increased risk of both in situ and invasive breast cancer. We investigated whether or not physical activity had a dose–response effect in lowering plasma levels of prolactin in postmenopausal women.

Methods

Four hundred previously inactive but healthy postmenopausal women aged 50–74 years of age were randomized to 150 or 300 min per week of aerobic physical activity in a year-long intervention. Prolactin was measured from fasting samples with a custom-plex multiplex assay.

Results

A high compared to moderate volume of physical activity did not reduce plasma prolactin levels in intention-to-treat (Treatment Effect Ratio (TER) 1.00, 95% Confidence Interval (CI) 0.95 – 1.06) or per-protocol analyses (TER 1.02, 95% CI 0.93 – 1.13).

Conclusions

It is unlikely that changes in prolactin levels mediate the reduced risk of breast cancer development in post-menopausal women associated with increased levels of physical activity.
