Prevenção, risco e desejo: estudo acerca do não uso de preservativos

Objective: To outline the causes that led men and women not to use condoms at the last sexual intercourse with casual partners. Methods: This is a documentary study, composed of 10,175 users attended to at a Counseling and Testing Center (CTC) in a capital city of the Brazilian Northeast. Variables are marital status, sex and the reasons for non-use of condoms in sexual intercourses. Data on the retrospective period from 2012 to 2014, collected in 2015, was submitted to treatment, by means of descriptive statistics, and was quantitatively tabulated. Results: The reason for not using condoms with the last casual partner had a total of 1,372 occurrences, distributed as 984 (71.7%) in the male population and 388 (28.2%) in the female. The most prevalent reason in relation to the non-use of the condom is the dislike, presenting 442 (32.2%) occurrences in both sexes. The reason with less incidence is that the partner does not accept it, with 81 (20.8%) cases and only among women; 143 (23.3%) occurrences were found only among single men, under the effect of alcohol and drugs. Conclusion: The users of the Counseling and Testing Center investigated presented, as prevalent reason for the non-use of condoms during sexual intercourses the fact of “not liking it”, for both sexes, since men and women, regardless of marital status, have confirmed that they do not use the condom with a casual partner.
General expressions of derivative-constrained linear-phase type-I FIR filters

In this paper, we propose a novel structure of linear-phase type-I FIR filters. The structure consists of a linear combination of some basic filters, called the cardinal filters. The weighting coefficients are exactly the derivatives of the amplitude response at ω = 0. We solve a closed-form recurrence relationship between the filter coefficients. Implementation of the cardinal filters is discussed.
Detecting cardiorespiratory Coordination by Respiratory Pattern Analysis of Heart Period Dynamics - the Musical rhythm Approach

The purpose of this study was to demonstrate that cardiorespiratory coordination can be unveiled by analyzing solely heart period data from the electrocardiogram (ECG). The analysis was done (1) on the basis of symbolic musical pattern analysis to detect intermittent cardiorespiratory phase coordination and (2) on the quantitative evaluation of respiratory sinus arrhythmia (RSA) to examine long-term frequency coordination between heartbeat and respiration. The methods were applied to 196 ECGs of 98 healthy subjects. The results showed that at night (1) intermittent phase coordination occurred reproducibly in individual subjects, and (2) long-term frequency ratios statistically approached 4:1 over all subjects to within an accuracy of 0.02, although individual values ranged from 2.5 – 6.0 with a high intraindividual reproducibility (r = 0.94, day A vs. day B). Moreover, intermittent phase coordination ratios and long-term frequency ratios corresponded to each other with a remarkably high correlation (r = 0.95). In the light of clinical applications, the coordination analysis presented here has an enormous advantage over those techniques depending on respiratory flow measurements, because the pattern technique requires only ECG recordings, and it is thus applicable over a longer period of time under daily life conditions.
Examination of Complicated Grief, Posttraumatic Stress, and Other Psychological Reactions among Student Survivors of the April 16th Shootings at Virginia Tech

The diagnosis of Complicated Grief (CG) is being proposed for inclusion in DSM–5. As such, it has been the focus of several studies purporting to build evidence of its validity and its conceptual and statistical distinction from Posttraumatic Stress Disorder (PTSD) and depression (Bonanno et al., 2007; Golden & Dalgleish, 2010; Prigerson et al., 1995b). However, previous research has focused predominantly on bereavement caused by non-violent means (e.g., prolonged terminal illness). This study attempts to explore the nature of CG among a sample of students who survived a mass shooting. Exploratory and confirmatory factor analytic procedures were used to examine and confirm the factor structure of CG as reported in previous studies (e.g., Boelen & van den Bout, 2005; Dillen, Fontaine, & Verhofstadt-Denève, 2008). A refined CG scale was then used as a criterion to demonstrate how different types of traumatic exposure contribute to symptoms of CG and/or posttraumatic stress (PTS). It was hypothesized that exposure items related to bereavement would be more related to CG than to PTS, whereas direct exposure to the shootings would be more closely related to PTS than to CG. Results of exploratory and confirmatory factor analyses supported CG as a unitary construct distinct from PTS and from anxiety/depression. Logistic regression results demonstrated that bereavement status was significantly predicted by CG but not PTS: Participants who scored 1 standard deviation above the mean on the CG scale were 14.64 times more likely to have been bereaved than were those who scored at the mean. SEM analyses were used to provide an additional test of this hypothesis. The final model had acceptable fit as assessed by RMSEA = . 046, CI = . 043– . 049, SRMR = . 048, and CFI = . 990; however, the Satorra-Bentler Scaled χ 2 = 1507.82, df = 589, p < . 001, did not support the model. Overall, results of SEM suggested that interpersonal loss (i.e., whether a friend was killed, injured, or escaped from the shootings) predicted CG but not PTS, whereas perceived threat predicted both CG and PTS.
Changes in the health status of newly housed chronically homeless: the Alaska Housing First program evaluation

ABSTRACT The Housing First (HF) model is an evidence-based supportive housing initiative that provides permanent housing for the homeless without preconditions such as sobriety or treatment compliance. This three-year longitudinal study investigated the effects of Alaska's inaugural Housing First projects in Anchorage and Fairbanks on local service usage, costs and tenant quality of life (QoL). A total of 94 tenants participated at baseline in the QoL study and 68 continued to follow-up. Cost data was collected from local municipalities, Alaska Department of Corrections, and local hospitals, health care clinics, behavioral health providers, and detox facilities. Emergency services use by tenants decreased from the year before moving into Housing First to the year after. Changes in health care costs were more variable depending on site and type of service.
Burnout, Fatigue, Exhaustion: An Interdisciplinary Perspective on a Modern Affliction

Our age, it seems, is the age of exhaustion. The prevalence of exhaustion – both as an individual experience and as a broader socio-cultural phenomenon – is manifest in the epidemic rise of burnout, depression, and chronic fatigue. It is equally present in a growing disenchantment with capitalism in its current neo-liberal form, in concerns about the psycho-social repercussions of ever-faster information and communication technologies, in a general distrust in grand narratives, and in anxieties about ecological sustainability. Since the precise organic causes of chronic exhaustion are still being debated, exhaustion theories entail by definition assumptions about the relationship between the mind, the body, and society, which are often ideologically charged. Exhaustion theories frequently act as discursive spaces in which specific cultural discontents are negotiated. They therefore present fascinating case studies for an investigation of the ways in which individual discomfort and wider social dynamics are interrelated. This multidisciplinary essay collection explores the connections and tensions between sociological, psychological, and biologic theories of exhaustion. Examining the status of exhaustion-syndromes in sociological, medical, psychological, psychiatric, literary, and historical accounts, it provides groundbreaking analyses of the complex interplay between the processes involved in the production of mental health diagnoses, socio-cultural transformations, and subjective illness experiences.
An Analysis of Gradual Patch Application: A Better Explanation of Patch Acceptance

Patch submission has been known as one of the most important activities to sustain the open source software (OSS). The patch archive can be analyzed to procure many benefit cognizance for supporting the OSS project works. The recent models and methods that analyze the patches acceptance are quite rack of comprehensive; hence, complex activities such as a committer portioning the Passed QA patch out and accept are still excluded from the analysis. Therefore, the results derived from those methods would be inadequate to conclude the actual patch acceptance. In this research, we introduce an algorithm for analyzing patch acceptance including the partial and gradually accepted conditions. Validating our algorithm, we present our methods for indicating the partial and gradual application of the Passed QA patch between either mailing list and SVN or Bugzilla and CVS which are the commonly deployed patch-activities related system. We studied on two well known OSS projects; Apache HTTP and Eclipse Platform. We obtained a fascinating conclusion that larger patches have more confident to be accepted than the smaller contradicted to other analysis that came from the recent methods.
Asymptotic cones of Lie groups and cone equivalences

We introduce cone bilipschitz equivalences between metric spaces. These are maps, more general than quasi-isometries, that induce a bilipschitz homeomorphism between asymptotic cones. Non-trivial examples appear in the context of Lie groups, and we thus prove that the study of asymptotic cones of connected Lie groups can be reduced to that of solvable Lie groups of a special form. We also focus on asymptotic cones of nilpotent groups.
Coexpression analysis of nine neuropeptides in the neurosecretory preoptic area of larval zebrafish

The paraventricular nucleus (PVN) of the hypothalamus in mammals coordinates neuroendocrine, autonomic and behavioral responses pivotal for homeostasis and the stress response. A large amount of studies in rodents has documented that the PVN contains diverse neuronal cell types which can be identified by the expression of distinct secretory neuropeptides. Interestingly, PVN cell types often coexpress multiple neuropeptides whose relative coexpression levels are subject to environment-induced plasticity. Due to their small size and transparency, zebrafish larvae offer the possibility to comprehensively study the development and plasticity of the PVN in large groups of intact animals, yet important anatomical information about the larval zebrafish PVN-homologous region has been missing. Therefore we recently defined the location and borders of the larval neurosecretory preoptic area (NPO) as the PVN-homologous region in larval zebrafish based on transcription factor expression and cell type clustering. To identify distinct cell types present in the larval NPO, we also generated a comprehensive 3D map of 9 zebrafish homologs of typical neuropeptides found in the mammalian PVN (arginine vasopressin (AVP), corticotropin-releasing hormone (CRH), proenkephalin a (penka)/b (penkb), neurotensin (NTS), oxytocin (OXT), vasoactive intestinal peptide (VIP), cholecystokinin (CCK), and somatostatin (SST)). Here we extend this chemoarchitectural map to include the degrees of coexpression of two neuropeptides in the same cell by performing systematic pairwise comparisons. Our results allowed the subclassification of NPO cell types, and differences in variability of coexpression profiles suggest potential targets of biochemical plasticity. Thus, this work provides an important basis for the analysis of the development, function, and plasticity of the primary neuroendocrine brain region in larval zebrafish.
Lead-free soldering and low alpha solders for wafer level interconnects

Lead-free soldering, originally started as an environmental issue, is evolving rapidly into a business survival tool for the worldwide electronic industry. Promising lead-free solder alternatives for surface mount assembly applications include eutectic Sn/Ag, eutectic Sn/Cu, Sn95/Sb5, eutectic Sn/Bi, Sn/Ag/Cu, Sn/Ag/Cu/X, Sn/Bi/Ag/X, Sn/Zn/X, and Sn/In/Ag/(X). However, for wafer level area array solder bump interconnects, most of those options fall short in terms of fatigue resistance. Sn/In/Ag/(X) appears to be superior when compared with Sn63/Pb37, as demonstrated by Sn/In/Ag/Cu. For applications involving high lead solders, no solder alternatives have been developed yet. While the industry is advancing toward being finer, smaller, lighter, and faster, wafer level packages using area array solder interconnects is suffering from the soft error due to alpha emission from the lead in the solders. Although lead-free solder alternatives for eutectic Sn/Pb are virtually free from alpha emission, the continuous dependence on the use of high-lead solders for C4 applications indicates that the challenge of alpha emission from lead-containing solders will persist regardless of the lead-free move of the industry. This challenge is getting tougher with the rapid advancement of IC design toward further miniaturization. Low alpha lead can be obtained from cold lead ore, old lead, and laser isotope separation process, with the latter having potential as a long term solution. The price of those low alpha lead is very expensive when compared with the regular lead. Due to the increase in I/O density, requirement on alpha emission level may soon move from LC2 to LC3 level. The supply of low alpha lead for wafer level interconnects does not seem to be an issue.
MYCN and HDAC2 cooperate to repress miR-183 signaling in neuroblastoma

MYCN is a master regulator controlling many processes necessary for tumor cell survival. Here, we unravel a microRNA network that causes tumor suppressive effects in MYCN-amplified neuroblastoma cells. In profiling studies, histone deacetylase (HDAC) inhibitor treatment most strongly induced miR-183. Enforced miR-183 expression triggered apoptosis, and inhibited anchorage-independent colony formation in vitro and xenograft growth in mice. Furthermore, the mechanism of miR-183 induction was found to contribute to the cell death phenotype induced by HDAC inhibitors. Experiments to identify the HDAC(s) involved in miR-183 transcriptional regulation showed that HDAC2 depletion induced miR-183. HDAC2 overexpression reduced miR-183 levels and counteracted the induction caused by HDAC2 depletion or HDAC inhibitor treatment. MYCN was found to recruit HDAC2 in the same complexes to the miR-183 promoter, and HDAC2 depletion enhanced promoter-associated histone H4 pan-acetylation, suggesting epigenetic changes preceded transcriptional activation. These data reveal miR-183 tumor suppressive properties in neuroblastoma that are jointly repressed by MYCN and HDAC2, and suggest a novel way to bypass MYCN function.
A Social-Psychological Approach To Conflict Resolution: Interactive Problem Solving

Track II diplomacy has gained currency on the international scene since the last quarter of the twentieth century. Herbert C. Kelman, a leading scholar in social sciences and a pioneer in interactive conflict resolution, has contributed to this field by applying social-psychological concepts to the analysis and resolution of conflict. In this article, the conceptual basis of Kelman’s interactive problem solving approach will be appraised as well as his work on the Israeli-Palestinian conflict. The Israeli-Palestinian workshops that Kelman and his colleagues held for more than twenty years have been influential especially in the prenegotiation process leading to the Oslo Agreement.
Super-Exponential Solution for a Retrial Supermarket Model

In this paper, we provide a new and effective approach for studying super-exponential solution of a retrial supermarket model with Poisson arrivals, exponential service times and exponential retrial times and with two different probing-server numbers. We describe the retrial supermarket model as a system of differential equations by means of density-dependent jump Markov processes, and obtain an iterative algorithm for computing the fixed point of the system of differential equations. Based on the fixed point, we analyze the expected sojourn time that a tagged arriving customer spends in this system, and use numerical examples to indicate different influence of the two probing-server numbers on system performance including the fixed point and the expected sojourn time. Furthermore, we analyze exponential convergence of the current location of the retrial supermarket model to the fixed point, and apply the Kurtz Theorem to study density-dependent jump Markov process given in the retrial supermarket model, which leads to a Lipschitz condition under which the fraction measure of the retrial supermarket model weakly converges to the system of differential equations. This paper arrives at a new understanding of how the workload probing can help in load balancing jobs in retrial supermarket models.
The Design of Video-Based Professional Development: An Exploratory Experiment Intended to Identify Effective Features

Although video cases and video clubs have become popular forms of teacher professional development, there have been few systematic investigations of designs for such programs. Programs may vary according to (a) whether teachers watch videos of their own/their peers’ instruction, or whether teachers watch stock video of unknown teachers; and (b) whether discussions are led by trained facilitators or by participants themselves. Using a factorial design, we defined four treatment conditions based on these possibilities, then assigned three groups of teachers to each condition. Teachers watched, scored, and discussed mathematics instruction according to each treatment condition’s protocol. Evidence from groups’ conversations and teachers’ video analyses and lesson reflections suggest that the teacher-led, own-video condition is slightly superior to the other conditions.
Modelling feedback from stars and black holes in galaxy mergers

We describe techniques for incorporating feedback from star formation and black hole (BH) accretion into simulations of isolated and merging galaxies. At present, the details of these processes cannot be resolved in simulations on galactic scales. Our basic approach therefore involves forming coarse-grained representations of the properties of the interstellar medium (ISM) and BH accretion starting from basic physical assumptions, so that the impact of these effects can be included on resolved scales. We illustrate our method using a multiphase description of star-forming gas. Feedback from star formation pressurizes highly overdense gas, altering its effective equation of state (EOS). We show that this allows the construction of stable galaxy models with much larger gas fractions than possible in earlier numerical work. We extend the model by including a treatment of gas accretion onto central supermassive BHs in galaxies. Assuming thermal coupling of a small fraction of the bolometric luminosity of accreting BHs to the surrounding gas, we show how this feedback regulates the growth of BHs. In gas-rich mergers of galaxies, we observe a complex interplay between starbursts and central active galactic nuclei (AGN) activity when the tidal interaction triggers intense nuclear inflows of gas. Once an accreting supermassive BH has grown to a critical size, feedback terminates its further growth and expels gas from the central region in a powerful quasar-driven wind. Our simulation methodology is therefore able to address the coupled processes of gas dynamics, star formation and BH accretion during the formation of galaxies.
Mindlessness, Submissive Behavior and Thought Suppression: A Perceptual Buffering of Self-Compassion to Psychological Vulnerabilities Among Indians

This study was designed to study the relationship among mindlessness, self-compassion, submissive behavior, thought suppression, depression, anxiety and stress among university students. The sample consisted of 100 university students, in the age range of 17-22 years from private universities viz., Banasthali University, K.N. Modi University and Dayalbagh Educational Institute. Standardized psychological tests were administered for the purpose of the study. Results indicate negative correlation among self-compassion, submissive behavior, mindlessness, thought suppression, depression and anxiety. Positive correlation was observed among submissive behavior, mindlessness, thought suppression, depression and anxiety. When regression analysis was conducted, self-compassion emerged as a significant predictor of mindlessness, thought suppression, depression and anxiety
PD-L1: PD-1 interaction contributes to the functional suppression of T-cell responses to human uveal melanoma cells in vitro.

PURPOSE To assess the expression of PD-L1 on human uveal melanomas and its potential to suppress T-cell function. METHODS A panel of primary and metastatic uveal melanoma cell lines was evaluated for PD-L1 expression by RT-PCR and flow cytometric analysis. Uveal melanoma-containing eyes were examined for PD-L1 expression by immunohistochemistry. PD-L1 function was tested by coculturing IFN-gamma-pretreated uveal melanoma cells with activated Jurkat T cells for 48 hours and assessing T-cell production of IL-2 by ELISA. RESULTS Five of the nine primary and one of the five metastatic uveal melanoma cell lines tested constitutively expressed PD-L1 protein at various levels. However, all primary and metastatic uveal melanoma cell lines upregulated PD-L1 expression after stimulation with IFN-gamma. Immunohistochemistry demonstrated that PD-L1 was not expressed by primary uveal melanomas in situ. IL-2 production by activated Jurkat T cells was decreased significantly when the cells were cocultured with IFN-gamma-pretreated uveal melanoma cells. More than 70% of IL-2 production was restored by addition of either anti-PD-L1 or anti-PD-1 antibody to the coculture assays (P < 0.01). CONCLUSIONS Expression of PD-L1 by uveal melanoma cells regulates T-cell function by suppressing IL-2 production. The results imply that the presence of IFN-gamma in the tumor local microenvironment promotes upregulation of PD-L1 expression by uveal melanoma, which may, in part, promote immune escape by impairing T-cell function. The selective blockade of PD-L1 is a potential strategy in T-cell-based immunotherapy for uveal melanoma.
Olimid Preliminary Views on the Determinants of the Cost of Capital for the Emergent Market of Romania T

This paper investigates several factors affecting the cost of capital for listed Romanian companies. Although there is a large amount of literature investigating the drivers of the cost of capital internationally, there is currently little evidence from emergent markets. Based on a sample of 19 Romanian listed companies followed by financial analysts for the years 2008-2010, according to Thomson Reuters’ I/B/E/S data base, the paper confirms the international trends, showing that size, corporate governance policies, and growth are negatively correlated with the cost of capital. Keywords—Corporate governance, determinants of the cost of capital, emergent markets.
