The challenge of parenting girls in neighborhoods of different perceived quality
It is well-known that disadvantaged neighborhoods, as officially identified through census data, harbor higher numbers of delinquent individuals than advantaged neighborhoods. What is much less known is whether parentsā perception of the neighborhood problems predicts low parental engagement with their girls and, ultimately, how this is related to girlsā delinquency, including violence. This paper elucidates these issues by examining data from the Pittsburgh Girls Study, including parent-report of neighborhood problems and level of parental engagement and official records and girl-reported delinquency at ages 15, 16, and 17. Results showed higher stability over time for neighborhood problems and parental engagement than girlsā delinquency. Parentsā perception of their neighborhood affected the extent to which parents engaged in their girlsā lives, but low parental engagement did not predict girls being charged for offending at age 15, 16 or 17. These results were largely replicated for girlsā self-reported delinquency with the exception that low parental engagement at age 16 was predictive of the frequency of girlsā self-reported delinquency at age 17 as well. The results, because of their implications for screening and early interventions, are relevant to policy makers as well as practitioners
The role of the family in HIV status disclosure among women in Vietnam: Familial dependence and independence
Ā© 2018 Taylor & Francis Group, LLC. Insights into disclosure by people living with HIV and AIDS (PLWHA) can inform strategies for treatment and support, yet Vietnamese women's self-disclosure patterns are poorly understood. We conducted interviews with 12 HIV-positive women, identifying three principal factors influencing disclosure to family members: patrilocal residence, desire to protect own family, and the need for financial support. Women's decision-making about disclosure was significantly affected by dependence on or independence of parents-in-law and their own parents. We believe that our findings reveal the complex interplay of stigma and disclosure within Vietnamese families, highlighting the need for specific social measures that promote self-disclosure combined with family support for female PLWHA
Longitudinal Profiles of Girls' Irritable, Defiant and Antagonistic Oppositional Symptoms: Evidence for Group Based Differences in Symptom Severity
Three subdimensions of ODD symptoms have been proposed -angry/irritable (IR), argumentative/defiant (DF) and antagonism (AN). This study tested whether longitudinal symptom trajectories could be identified by these subdimensions. Group-based trajectory analysis was used to identify developmental trajectories of IR, DF and AN symptoms. Multi-group trajectory analysis was then used to identify how subdimension trajectories were linked together over time. Data were drawn from the Pittsburgh Girls Study (PGS; NĀ =Ā 2450), an urban community sample of girls between the ages of five--eight at baseline. We included five waves of annual data across ages five-13 to model trajectories. Three trajectories were identified for each ODD subdimension: DF and AN were characterized by high, medium and low severity groups; IR was characterized by low, medium stable, and high increasing groups. Multi-trajectory analysis confirmed these subdimensions were best linked together based on symptom severity. We did not identify girls' trajectory groups that were characterized predominantly by a particular subdimension of ODD symptoms. Membership in more severe symptom groups was significantly associated with worse outcomes five years later. In childhood and early adolescence girls with high levels of ODD symptoms can be identified, and these youth are characterized by a persistently elevated profile of IR, DF and AN symptoms. Further studies in clinical samples are required to examine the ICD-10 proposal that ODD with irritability is a distinct or more severe form of ODD
A New Validation Method for X-ray Mammogram Registration Algorithms Using a Projection Model of Breast X-ray Compression
Noninvasive diffusion magnetic resonance imaging of brain tumour cell size for the early detection of therapeutic response
Cancer cells differ in size from those of their host tissue and are known to change in size during the processes of cell death. A noninvasive method for monitoring cell size would be highly advantageous as a potential biomarker of malignancy and early therapeutic response. This need is particularly acute in brain tumours where biopsy is a highly invasive procedure. Here, diffusion MRI data were acquired in a GL261 glioma mouse model before and during treatment with Temozolomide. The biophysical model VERDICT (Vascular Extracellular and Restricted Diffusion for Cytometry in Tumours) was applied to the MRI data to quantify multi-compartmental parameters connected to the underlying tissue microstructure, which could potentially be useful clinical biomarkers. These parameters were compared to ADC and kurtosis diffusion models, and, measures from histology and optical projection tomography. MRI data was also acquired in patients to assess the feasibility of applying VERDICT in a range of different glioma subtypes. In the GL261 gliomas, cellular changes were detected according to the VERDICT model in advance of gross tumour volume changes as well as ADC and kurtosis models. VERDICT parameters in glioblastoma patients were most consistent with the GL261 mouse model, whilst displaying additional regions of localised tissue heterogeneity. The present VERDICT model was less appropriate for modelling more diffuse astrocytomas and oligodendrogliomas, but could be tuned to improve the representation of these tumour types. Biophysical modelling of the diffusion MRI signal permits monitoring of brain tumours without invasive intervention. VERDICT responds to microstructural changes induced by chemotherapy, is feasible within clinical scan times and could provide useful biomarkers of treatment response
Using Diffusion-Diffusion Exchange Spectroscopy to observe diffusion exchange in yeast
The permeability of cell membranes varies significantly across both healthy and diseased
tissue, and changes in cell membrane permeability can occur during treatment response in
tumours. Measurements of cell membrane permeability could therefore be useful for tumour
detection and as biomarkers of treatment response in the clinic. As the diffusion of water
across the cell membrane is directly dependent on cell membrane permeability, we have
investigated the ability of diffusion-diffusion exchange spectroscopy to quantify the diffusion
exchange of water in a suspension of yeast, as a first step towards its application in tumours
Girls' disruptive behavior and its relationship to family functioning: A review
Although a number of reviews of gender differences in disruptive behavior and parental socialization exist, we extend this literature by addressing the question of differential development among girls and by placing both disruptive behavior and parenting behavior in a developmental framework. Clarifying the heterogeneity of development in girls is important for developing and optimizing gender-specific prevention and treatment programs. In the current review, we describe the unique aspects of the development of disruptive behavior in girls and explore how the gender-specific development of disruptive behavior can be explained by family linked risk and protective processes. Based on this review, we formulate a gender-specific reciprocal model of the influence of social factors on the development of disruptive behavior in girls in order to steer further research and better inform prevention and treatment programs
Stres na radu i zdravlje medicinskih sestara u jedinicama intenzivne njege u Srbiji
The aim of this study was to identify and analyse professional stressors, evaluate the level of stress in nurses in Intensive Care Units (ICU), and assess the correlation between the perception of stress and psychological and somatic symptoms or diseases shown by nurses. The research, designed as a crosssectional study, was carried out in the Intensive Care Units (ICU), in health centres in Serbia. The sample population encompassed 1000 nurses. Expanded Nursing Stress Scale (ENSS) was used as the research instrument. ENSS revealed a valid metric characteristic within our sample population. Nurses from ICUs rated situations involving physical and psychological working environments as the most stressful ones, whereas situations related to social working environment were described as less stressful; however, the differences in the perception of stressfulness of these environments were minor. Socio-demographic determinants of the participants (age, marital status and education level) significantly affected the perception of stress at work. Significant differences in the perception of stressfulness of particular stress factors were observed among nurses with respect to psychological and somatic symptoms (such as headache, insomnia, fatigue, despair, lower back pain, mood swings etc.) and certain diseases (such as hypertension, myocardial infarction, stroke, diabetes mellitus etc). In view of permanent escalation of professional stressors, creating a supportive working environment is essential for positive health outcomes, prevention of job-related diseases and better protection of already ill nurses.Cilj je ovoga rada bio identifi cirati i analizirati profesionalne stresore, procijeniti razinu stresa kod medicinskih sestara u jedinicama intenzivne njege te procijeniti korelaciju izmeÄu percepcije stresa i prisutnosti psiholoÅ”kih i somatskih simptoma ili bolesti kod medicinskih sestara. Istraživanje je provedeno u obliku studije presjeka u Jedinicama intenzivne njege u zdravstvenim centrima u Srbiji. Uzorak se sastojao od 1000 medicinskih sestara-tehniÄara. Za procjenu i analizu profesionalnih stresora koriÅ”ten je upitnik Expanded Nursing Stress Scale (ENSS), koji je pokazao validne metrijske karakteristike na naÅ”oj ispitanoj populaciji. Medicinske sestre u Jedinicama intenzivne njege ocijenile su situacije iz fiziÄkoga i psiholoÅ”koga radnog okruženja kao izrazito optereÄujuÄe, a situacije iz socijalnoga radnog okruženja kao manje optereÄujuÄe. Razlika u percepciji stresogenosti navedenih radnih okruženja nije bila statistiÄki znaÄajna. Sociodemografske determinante ispitanika (dob, braÄno stanje i stupanj obrazovanja) znaÄajno utjeÄu na percepciju stresa na radnom mjestu. UtvrÄena je statistiÄki znaÄajna razlika u opažanju stresogenosti pojedinih stresnih situacija na radnom mjestu izmeÄu medicinskih sestara u odnosu na postojanje psihosomatskih simptoma (kao Å”to su glavobolja, nesanica, umor, oÄaj, bol u leÄima, Äeste promjene raspoloženja) ili odreÄenih bolesti (kao Å”to su poviÅ”ena hipertenzija, infarkt miokarda, cerebrovaskularni inzult, Å”eÄerna bolest). Zbog sve izraženije prisutnosti profesionalnih stresora nužno je poduzeti odreÄene strateÅ”ke mjere kod medicinskih sestara u Jedinicama intenzivne njege. StrateÅ”ke mjere podrazumijevaju unaprjeÄenje psihosocijalne radne klime, Å”to bi unaprijedilo njihovo zdravlje i sprijeÄilo nastanak bolesti u svezi s radom, ali i omoguÄilo bolju zaÅ”titu veÄ oboljelim medicinskim sestrama
