PTSD and HIV in Women: The Role of Gender in This Dual Diagnosis

This article is based on the authors findings from a cross-sectional descriptive study of men (n = 116) and women (n = 68) who were receiving HIV/AIDS counseling from four different community centers across New York state from March–July 2010. To ascertain the prevalence of post-traumatic stress in this population, a checklist (PCL) was employed. The responses from females and males were compared to detect gender differences in the common dual diagnosis of HIV and PTSD. The genders differed regarding several manifestations of PTSD: (1) women reported a significantly higher mean score on “feeling very upset when something reminded” them of a stressful experience from the past; (2) while not statistically significant, but noteworthy, men reported they were more likely to feel “distant or cut off” depending on their employment status. These and other findings suggested that the genders may manifest PTSD differently. Implications for those in the health care field and the trauma field are provided.
Towards Generating Recommendations on Large Dynamically Growing Domains

Overwhelming increase in the amount of information raise a requirement of personalized recommendation system. A vast amount of studies have applied traditional collaborative filtering (CF) techniques for generating recommendations. However, well-known scalability issue imposes a limit on its general application. Association Rule based CF techniques where the association rules are primarily generated on items have also been considered but the approaches turned out inefficient with the rapid growth of item space. We anticipated a promising solution of these issues could be diminution in the cardinality of the large user-item rating matrix. Thus, instead of generating associations among the dynamically growing items, generation of associations among the categories, which is quasi-static in practice, could be a convenient route. Herein, we have proposed an elegant approach to generate recommendations using association rule based CF approach on categories. To evaluate the method, we have experimented with real world mobile application user data from Mobilewalla (Mobilewalla is a venture capital backed company which accumulates data for mobile applications from four major platforms, Apple, Android, Windows, and Blackberry). Two new measures are introduced for calculating accuracy. Findings show that our method scales well on dynamic mobile application domain with legitimate accuracy.
Rural Women and Climate Change: A Gender-inclusive Perspective

Abstract This paper reports on a small-scale research study that explores the impact of climate change on rural women. Qualitative data were collected through interviews with 7 women, who came from a regional centre and were either employed by women's services or who had activist roles within the community pertaining to women's services. Outcomes of the study identified a range of areas of impact, including increased hardship for rural women, implications of household roles, and subsequent organisational responsibilities. A high level of concern, particularly for the vulnerability of women in crisis, was identified among participants. We contend that the effects of climate change are becoming increasingly relevant to the social work profession and that specific groups such as women are at risk of further disadvantage unless collective action is taken to circumvent the impact of climate change. Strategies for social work practice and policy initiatives are considered.
The Emergence of Psychiatric Disabilities in Postsecondary Education

A significant development in the field of postsecondary disability supports in the last decade has been the proliferation of individuals with psychiatric disabilities. This phenomenon has emerged at a pace that one observer characterized as a “rising tide” (Eudaly, 2002). Measel (1998) found that within one year, five institutions in the Big Ten Conference encountered an increase from 30% to 100% in the number of students served with psychiatric disabilities. At one institution, the University of Minnesota, the number of students reporting a psychiatric disability as their primary disability (285) was more than the combination of students reporting learning disabilities and attention deficit disorders (269). Although there is little systematically collected data to provide a reliable estimate of the emergence of psychiatric disabilities in postsecondary education, information from current sources provides evidence that this issue is likely to come into sharper focus as data from more studies become available.
First steps in programming: a rationale for attention investment models

Research into the cognitive aspects of programming originated in the study of professional programmers (whether experts or students). Even "end-user" programmers in previous studies have often worked in organizations where programming is recognized to be demanding professional work-the term "power-user" recognizes this technical kudos. But as personal computers become widespread, and most new domestic appliances incorporate microprocessors, many people are engaging in programming-like activities in domestic or nonprofessional contexts. Such users often have less motivation and more obstacles to programming, meaning that they may be unlikely even to take the first steps. This paper analyses the generic nature of those first steps, and identifies the cognitive demands that characterize them. On the basis of this analysis the paper proposes the attention investment model, a cognitive model of programming that offers a consistent account of all programming behaviour, from professionals to end-users.
Terrenolide S, a new antileishmanial butenolide from the endophytic fungus Aspergillus terreus

Abstract Terrenolide S, a new butenolide derivative (6), together with six known compounds: (22E,24R)-stigmasta-5,7,22-trien-3-β-ol (1), stigmast-4-ene-3-one (2), stigmasta-4,6,8(14),22-tetraen-3-one (3), terretonin A (4), terretonin (5) and butyrolactone VI (7) have been isolated from the endophytic fungus Aspergillus terreus isolated from the roots of Carthamus lanatus (Asteraceae). Their structures were established by extensive spectroscopic analyses (1D, 2D NMR and HRESIMS), as well as optical rotation measurement and comparison with literature data. Compound 1 displayed a potent activity towards methicillin-resistant Staphylococcus aureus (MRSA) and Cryptococcus neoformans with IC50 values of 2.29 and 10.68 µM, respectively. Moreover, 1, 2 and 6 exhibited antileishmanial activity towards Leishmania donovani with IC50 values of 11.24, 15.32 and 27.27 µM, respectively and IC90 values of 14.68, 40.56 and 167.03 µM, respectively.

In whose words? Struggles and strategies of service providers working with immigrant clients with limited language abilities in the violence against women sector and child protection services

Newcomer and immigrant clients with limited language abilities face communication barriers that can compromise their capacity to make informed decisions about themselves and their children with serious implications for their families. These clients most likely had high proficiency of language in their country of origin but are learning the language of the new host country. Using a phenomenological design to elicit descriptions from and interpret experiences of Canadian-helping professionals, we conducted four focus groups first with child protection workers, and second with violence against women service providers. Analyses of these data uncovered five themes: (1) enhancing client engagement and self-agency; (2) advantages and drawbacks in use of interpreters; (3) creative and intensive translation strategies; (4) structural challenges and (5) gender and cultural considerations. Results are organized into an ecological framework in putting forward implications for policy and practice. The over-arching finding supports that important training and preparation are necessary for service providers to deliver language-sensitive services. As well, funding levels need to be increased to better match service delivery goals. Newcomer and immigrant clients whose language needs are not adequately met potentially face safety issues and/or fragmentation of their families.
Lipschitz-Killing Curvatures of the Excursion Sets of Skew Student's t Random Fields

In many applications related with geostatistics, biological and medical imaging, material science, and engineering surfaces, the real observations have asymmetric and heavy-tailed multivariate distributions. These observations are spatially correlated and they could be modeled by the skew random fields. However, several statistical analysis problems require studying the integral geometry of these random fields in order to detect the local changes between the different samples, via the expected Euler-Poincaré characteristic and the intrinsic volumes (Lipschitz-Killing curvatures) of the excursion set obtained at a given threshold. This article is interested in a class of skew random fields, namely, skew Student's t random field. The goal is to derive an explicit formula of Lipschitz-Killing curvatures and the expected Euler-Poincaré characteristic of the skew Student's t excursion sets on a compact subset S of ℝ2 by extending previous results reported in the literature. The motivation comes from the need to model the roughness of some engineering surfaces in order to detect the local changes of the surface peaks/valleys during a specific physical phenomenon. The analytical and empirical Euler-Poincaré characteristics are compared in order to test the skew Student's t random field on the real surface. Simulation results are also presented in the article for illustration and validation.
Polynomial Representations of Polar Codes and Decoding under Overcomplete Representations

This letter proposes an alternative expression of polar codes using polynomial representations. Polynomial representations may help to explore further algebraic properties of polar codes, same as those for convolutional codes. The relationship between message and codeword polynomials of polar codes indicates that polar codes are highly related to convolutional codes with generator polynomials 1+D and 1/(1+D). By using polynomial representations, we show the input and output bit shift properties of polar codes. This property is then employed to construct redundant trellises for overcomplete representations. Simulation results show that belief propagation (BP) decoding over the proposed overcomplete representation can achieve a significant performance gain as compared with BP decoding over the overcomplete representation using trellis permutations.
Investigation of the Correlation Between Trust and Reputation in B2C e-Commerce Using Alexa Ranking

As a general approach to gain electronic trust in business-to-consumer e-commerce, the customers select valid brands based on the authenticity of the Web and regulatory mechanisms in order to facilitate purchase decision process. This approach is not suitable for purchase from small companies without brands active in e-commerce. To purchase from these companies, we should follow other e-trust approaches. One of the approaches applied in information literate is to refer to valid ranking sites like Alexa rank. Here, we have evaluated the correlation between Alexa rank and the formal measures of trust in electronic space, and have suggested a new method for the e-trust that is based on an electronic reputation built on the existing ranking results given by the ranking sites. To this end, we selected 100 store Websites based on regulatory lists, and the formal criteria of trust for them were measured along with the correlation of these criteria with Alexa rank.
A Comparison of Natural (D-α-tocopherol) and Synthetic (DL-α-tocopherol Acetate) Vitamin E Supplementation on the Growth Performance, Meat Quality and Oxidative Status of Broilers

The present study was conducted to compare the supplementation of natural (D-α-tocopherol) and synthetic (DL-α-tocopherol acetate) vitamin E on the growth performance, meat quality, muscular antioxidant capacity and genes expression related to oxidative status of broilers. A total of 144 1 day-old Arbor Acres broiler chicks were randomly allocated into 3 groups with 6 replicates of 8 birds each. Birds were given a basal diet (control group), and basal diet supplemented with either 20 IU D-α-tocopherol or DL-α-tocopherol acetate for 42 days, respectively. The results indicated that treatments did not alter growth performance of broilers (p>0.05). Compared with the control group, concentration of α-tocopherol in the breast muscle was increased by the supplementation of vitamin E (p<0.05). In the thigh, α-tocopherol content was also enhanced by vitamin E inclusion, and this effect was more pronounced in the natural vitamin E group (p<0.05). Vitamin E supplementation increased the redness of breast (p<0.05). In the contrast, the inclusion of synthetic vitamin E decreased lightness of thigh (p<0.05). Dietary vitamin E inclusion reduced drip loss at 24 h of thigh muscle (p<0.05), and this effect was maintained for drip loss at 48 h in the natural vitamin E group (p<0.05). Broilers given diet supplemented with vitamin E showed decreased malondialdehyde (MDA) content in the breast (p<0.05). Additionally, natural rather than synthetic vitamin E reduced MDA accumulation in the thigh (p<0.05). Neither natural nor synthetic vitamin E supplementation altered muscular mRNA abundance of genes related to oxidative stress (p>0.05). It was concluded that vitamin E supplementation, especially the natural vitamin E, can enhance the retention of muscular α-tocopherol, improve meat quality and muscular antioxidant capacity of broilers.
Detection of Coronary Microembolization by Doppler Ultrasound in Patients With Stable Angina Pectoris Undergoing Elective Percutaneous Coronary Interventions

Background— Intracoronary Doppler guidewires can be used for real-time detection and quantification of microembolism during percutaneous coronary interventions (PCIs). We investigated whether the frequency of Doppler-detected microembolism is related to the incidence of myonecrosis during elective PCI. Methods and Results— The study population included 52 consecutive patients (aged 64±10 years; 36 men, 16 women) with coronary artery disease who underwent elective PCI of a single-vessel stenosis. Using intracoronary Doppler ultrasound, we compared the frequency of microembolism during PCI in 22 patients with periprocedural non–ST-segment elevation myocardial infarctions (pNSTEMI) and 30 patients without pNSTEMI. The 2 groups were comparable with regard to their clinical and procedural characteristics. In the group with pNSTEMI, the total number of coronary microemboli after PCI (27±10 versus 16±8, P<0.001) was higher than in the group without pNSTEMI. Although high-sensitivity C-reactive protein plasma levels were similar before PCI (2.9±2.2 versus 3.4±1.7 mg/L, P=NS), they were higher in the group with pNSTEMI after PCI (12.6±10.4 versus 6.1±5.1 mg/L, P<0.05). Microembolic count independently correlated to postprocedural cardiac troponin I elevation (r=0.565, P<0.001), coronary flow velocity reserve (r=−0.506, P<0.001), and baseline average peak velocity (r=0.499, P<0.001). Conclusions— Patients with pNSTEMI had a significantly higher frequency of coronary microembolization during PCI, and their systemic inflammatory response and microvascular impairment after PCI were more pronounced. Intracoronary Doppler ultrasound provides evidence that pNSTEMI in patients undergoing elective PCI is caused by microembolization during the procedure.
Canonical Dual Method for Resource Allocation and Adaptive Modulation in Uplink SC-FDMA Systems

In this paper, we study resource allocation and adaptive modulation in SC-FDMA which is adopted as the multiple access scheme for the uplink in the 3GPP-LTE standard. A sum-utility maximization (SUmax), and a joint adaptive modulation and sum-cost minimization (JAMSCmin) problems are considered. Unlike OFDMA, in addition to the restriction of allocating a sub-channel to one user at most, the multiple sub-channels allocated to a user in SC-FDMA should be consecutive as well. This renders the resource allocation problem prohibitively difficult and the standard optimization tools (e.g., Lagrange dual approach widely used for OFDMA, etc.) can not help towards its optimal solution. We propose a novel optimization framework for the solution of these problems that is inspired from the recently developed canonical duality theory. We first formulate the optimization problems as binary-integer programming problems and then transform these binary-integer programming problems into continuous space canonical dual problems that are concave maximization problems. Based on the solution of the continuous space dual problems, we derive resource allocation (joint with adaptive modulation for JAMSCmin) algorithms for both the problems which have polynomial complexities. We provide conditions under which the proposed algorithms are optimal. We also propose an adaptive modulation scheme for SUmax problem. We compare the proposed algorithms with the existing algorithms in the literature to assess their performance.
Wake-up flooding: an asynchronous network flooding primitive

We present a new technique for overcoming the fundamental trade-off between energy-efficiency and end-to-end packet latency pervading all event-triggered wireless sensing applications. Instead of applying popular synchronous or pseudo-asynchronous protocols, we leverage state-of-the-art wake-up receivers to facilitate purely asynchronous rendezvous. We then extend the per-hop asynchrony into a multi-hop flooding primitive, termed Wake-up Flooding. We describe the underpinnings of the flooding primitive and present preliminary results of wake-up flooding implemented on a custom dual-radio wireless sensing platform deployed in an indoor testbed.
Compact Lowpass Filter with Wide StopBand using Open Stubs-Loaded Spiral Microstrip Resonant Cell

─ In this paper, a compact lowpass filter using open stubs-loaded spiral compact microstrip resonant cell (OSL-SCMRC) is presented. The proposed resonator is implemented to design the lowpass filter with the wide and high out-of-band rejection in the stop-band region. The lowpass filter has the insertion loss from DC to 5.29 GHz better than -0.1 dB and the return loss better than 19.3 dB. Moreover, the lowpass filter is shown to suppress the harmonics with -20 dB attenuation level from 6.71 GHz to 16.73 GHz result in a 10.02 GHz rejection band. The proposed resonator has an improved slow-wave factor, low radiation and scattering, with a compact size. The filter is designed, fabricated and measured. There is a good agreement between the measured and the simulated S-parameters. Index Terms ─ Low insertion loss, lowpass filter, microstrip resonator cell, open stubs-loaded, and wide stop-band.
Analytical derivation of emf waveforms in PM machines based on permanent magnet volume integration

An analytical expression is developed for predicting EMF waveforms resulting from permanent magnets (PM) in electrical machines. The expressions derived in the paper for the flux linkage are based on a volume integral over the PM volume, rather than the usual surface integral over the coil. The proposed method consists in applying a virtual current in the coil of the machine and calculating the magnetic field generated inside the PM volume. The EMF waveform is obtained by derivating the flux linkage with respect to time. Analytical expressions of the emf are given for various PM shapes and Halbach magnetization patterns. Experimental verifications of the waveforms obtained are presented in the paper, demonstrating the validity of the expressions obtained theoretically.
From text to landscape: locating, identifying and mapping the use of landscape features in a Swiss Alpine corpus

In this paper, we demonstrate how a large corpus, consisting of about 10 000 articles describing Swiss alpine landscapes and activities and dating back to 1864, can be used to explore the use of language in space. In a first step, we link landscape descriptions to geospatial footprints, which requires new methods to disambiguating toponyms referring to natural features. Secondly, we identify natural features used to describe landscapes, which are compared and discussed in the light of previous work based on controlled participant experiments in laboratory settings and more exploratory ethnographic studies. Finally, we use natural features in combination with geospatial footprints to investigate variations in landscape descriptions across space. Our contributions are threefold. Firstly, we show how a corpus composed of detailed descriptions of natural landscapes can be georeferenced and mapped using density surfaces and an adaptive grid linking footprints to articles. Secondly, 95 natural features are identified in the corpus, forming a vocabulary of terms reflecting known basic levels and their relationships to other more specific landscape features. Thirdly, we can explore the use of natural features in broader spatial and temporal contexts than is possible in typical ethnographic work, by exploring when and where particular terms are used within Switzerland with respect to our corpus. On the one hand, this enables us to characterize individual regions and, on the other hand, to measure similarity between regions, on the basis of associated natural features. Our methods could be adapted to different types of corpus, for instance, referring to fine granularity entities in urban landscapes. Our results are potential building blocks for attaching place-related descriptions to automatically generated sensor data such as photographs or satellite images.
A cumulative hierarchy of sets for constructive set theory

The von Neumann hierarchy of sets is heavily used as a basic tool in classical set theory, being an underlying ingredient in many proofs and concepts. In constructive set theories like CZF without the powerset axiom however, it loses much of its potency by ceasing to be a hierarchy of sets as its single stages become only classes. This article proposes an alternative cumulative hierarchy which does not have this drawback and provides examples of how it can be used to prove new theorems in CZF .
Multicultural Groups

This study examined the effects of constructive conflict on decision-making groups that were culturally diverse. In a laboratory exercise, 45 four-person groups recorded their recommendations and assumptions regarding a business problem, and afterward members individually completed a questionnaire on the experience. Ethnic minorities contributed considerably less to decisions than nonminorities did. However, with increasing use of constructive conflict, groups made more valid and more important assumptions, and the performance and reactions of ethnic minorities improved at rates either the same as or greater than those of nonminorities. to North American managers, who face growing ethnic diversity in the workplace, the practices of constructive conflict offer a promising approach to group decision making.
