Mapping of fourteen high-risk human papillomavirus genotypes by molecular detection in sexually active women in the West African sub-region

The aim of this study was to determine the distribution of high-risk human papillomavirus genotypes (HR-HPV) in women from the general population of five West African countries. This was a cross-sectional descriptive study, involving 2133 women from nine cities of five West African countries: Benin, Burkina Faso, Cote d'Ivoire, Niger and Togo. Women were screened for precancerous cervical lesions and HR-HPV infection. The detection of HR-HPV was done by a multiplex real-time PCR on extracted viral DNA. The average age of the women in this study was 35.06 ± 10.00 years with a range of 15 to 65 years. The overall prevalence of high-risk HPV infection among general population sample of women in five West African countries was 33.61% (717/2133). The prevalence of dysplasia was 8.81%. In decreasing order of frequency, the genotypes found were: HPV 52 followed by HPV 31, 59, 51, 66, 45, 68, 56, 56, 58, 35, 39, 18, 33 and 16. The prevalence of HPV16/18 (bivalent vaccine types) was 7.02%. This study reveals a high prevalence of HPV 52 in West Africa. The extent and diversity of HR-HPV genotypes in these West African countries deserve special attention for prevention. Key words: High-risk HPV, real time PCR, genotypes, women, epidemiology, West Africa.
Will They Share? Predicting Location Sharing Behaviors of Smartphone Users through Self-Reflection on Past Privacy Behaviors

—Location sharing is a particularly sensitive type of online information disclosure. To explain this behavior, we compared the effectiveness of using self-report measures drawn from the literature, behavioral data collected from mobile phones, and a new type of measure that represents a hybrid of self-report and behavioral data to contextualize users’ attitudes toward their past location sharing behaviors. This new measure was based on a reﬂective learning paradigm, where one reﬂects on past behavior to inform future behavior. Based on a study of Android smartphone users (N=114), we found that the construct ‘FYI About Myself’ and our new reﬂective measure of one’s comfort with sharing location with apps on the smartphone were the best predictors of location sharing behavior. Surprisingly, Behavioral Intention, a commonly used proxy for actual behavior, was not a signiﬁcant predictor. These results have important implications for privacy research and designing systems to meet users’ location sharing privacy needs.
A best-first branch-and-bound search for solving the transductive inference problem using support vector machines

In this paper, we present a new method for solving the trans-ductive inference problem whose objective is predicting the binary labels of a subset of points of interest of an unknown decision function. We attempt to learn a decision boundary using SVM. To obtain the maximal-margin hypothesis over labeled and unlabeled samples, we employ an admissible best-ﬁrst search based on margin values. Empirical evidence suggests that this globally optimal solution can obtain excellent results in the transduction problem. Due to the selection strategy used, the search algorithm explores only a small fraction of unlabeled samples making it eﬃciently applicable to median-sized datasets. We compare our results with the results obtained from the TSVM demonstrating better results in margin values.
Buffering Negative News: Individual-level Effects of Company Visibility, Tone, and Pre-existing Attitudes on Corporate Reputation

Building on the agenda-setting theory, this study investigates the effect of corporations’ visibility and tone in news coverage on reputation. More specifically, we examine the buffering role that prior reputation may have for the potential damaging impact of news coverage. Providing a stringent test of causality, data from an automated content analysis of Dutch online and print newspaper coverage (N = 5,235 articles) were linked to individual responses from a three-wave panel survey (N = 3,270 respondents) with repeated measurements of corporate reputation (12 organizations). The analyses show that mere exposure to corporations negatively affects reputation, whereas tone has a positive effect on reputation. It is furthermore shown that the effect of negative news is three times larger than the effect of positive news. Finally, in accordance with research on buffering effects of corporate reputation, we demonstrate that negative news is less influential for people holding more positive existing reputational attitudes.
Achieving Keyless CDNs with Conclaves

Content Delivery Networks (CDNs) serve a large and increasing portion of today’s web content. Beyond caching, CDNs provide their customers with a variety of services, including protection against DDoS and targeted attacks. As the web shifts from HTTP to HTTPS, CDNs continue to provide such services by also assuming control of their customers’ private keys, thereby breaking a fundamental security principle: private keys must only be known by their owner. We present the design and implementation of Phoenix, the first truly “keyless CDN”. Phoenix uses secure enclaves (in particular Intel SGX) to host web content, store sensitive key material, apply web application firewalls, and more on otherwise untrusted machines. To support scalability and multitenancy, Phoenix is built around a new architectural primitive which we call conclaves: containers of enclaves. Conclaves make it straightforward to deploy multi-process, scalable, legacy applications. We also develop a filesystem to extend the enclave’s security guarantees to untrusted storage. In its strongest configuration, Phoenix reduces the knowledge of the edge server to that of a traditional on-path HTTPS adversary. We evaluate the performance of Phoenix with a series of microand macro-benchmarks.
Plant based assisted therapy for the treatment of substance use disorders part 2 : beyond blurred boundaries.

Objective. This article aims to offer a vision of the centers at a global level that use derivatives of plants or animals for the treatment of substance use disorders, and to offer a reflection on the concept of drugs as medicinal or toxicant agents depending on the context of use, culture and policy. Methodology. Some practices coming from Africa, Asia, Europe and the Americas were considered, carrying out a research based on scientific literature, exchange of information with treatment centers, internet search and the personal experience of the authors. Results and Discussion. Different cases of the use of natural medicines are described including psychoactive derivatives of Tabernanthe iboga and Bufo alvarius. Conclusions. The blurred boundaries between considering drug consumption as a crime or as a health issue could be overcome by being inspired by the ancient wisdom of traditional medicines.
Statistical Analysis of BRDF Data for Computer Graphics and Metrology

—Characterizing the appearance of real-world surfaces is a fundamental problem in multidimensional reﬂec-tometry, computer vision and computer graphics. For many applications, appearance is sufﬁciently well characterized by the bidirectional reﬂectance distribution function. BRDF is one of the fundamental concepts in such diverse ﬁelds as multidimensional reﬂectometry, computer graphics and computer vision. In this paper, we treat BRDF measurements as samples of points from high-dimensional non-linear non-convex manifold. We argue that statistical data analysis of BRDF measurements has to account both for nonlinear structure of the data as well as for ill-behaved noise. Standard statistical methods can not be safely directly applied to BRDF data. Our study clariﬁes certain pitfalls in analysis of BRDF data, and helps to develop more reﬁned estimates and unsupervised learning procedures for BRDF models. We also apply the notion of Pitman closeness to compare different estimators and learning procedures for BRDF models. This criterion for comparison is loss function-free and seems to be especially appropriate for applications in metrology and in comparing different types of learning methods. Additionally, we outline a multiple testing procedure for testing a hypothesis that a material has diffuse reﬂection in a generalized sense.
ANGULAR KINEMATICS OF THE DEEP SQUAT TEST IN FUNCTIONAL MOVEMENT SCREEN ACCORDING TO THE SCORING SYSTEM

Functional movement is the ability to produce and maintain a balance between mobility and stability along the kinetic chain while performing fundamental patterns with accuracy and efficiency . Muscular flexibility, strength, coordination, balance, endurance, and movement efficiency are components necessary to achieve functional movement, which is integral to performance and sport-related skills and also in health promotion environments, like gyms for general population. Physically active people may face the risk of long or short term injuries and these injuries are commonly as lower extremity especially in sportive activities/ games and may occur after an intensive exercises or/and neuromuscular fatigue . Preventing injuries, it should be determined whether the athletes are in the risk group. One of the popular screening tool for this, is the Functional Movement Screen (FMS). FMS has demonstrated some efficacy in the prediction of injuries and is thus used by many practitioners to make recomActa Medica Mediterranea, 2017, 33: 651
How long does it take to ﬁx the code: A case study of OpenStack.

Code review is an excellent source of metrics that can be used to improve the software development process. Metrics bene(cid:12)ts varies from measuring the progress of a development team to investigating into software development policies and guidelines. Inthispaper, we analyse some of the absolute metrics , speci(cid:12)cally review process metrics . Our case study is the large open source cloud computing project OpenStack . We bring evidence of code review process response time by quantifying the time spent by developers to identify the bug reports in the issue tracking system ( bug triaging ) and the time they spent to carry out the reviewing process ( time to review ) in the code review system. Last, we contrast our (cid:12)ndings with the results of similar analysis from traditional software inspection conducted on the Lucent project and from open source software code review on six projects, including AMD, Microsoft, and Google-led projects. This analysis is one of the intermediate phases of a current research line. Conducted and funded under the SENECA, a EU project, the scope of the research is to analyse the process quality characterising key performance indicators of the software development processes.
Is Geographical Remoteness an Economic Disadvantage

Is the geographical location of a country deterministic to its level of economic development? Although economic geographers have been searching the answers to this question for decades, incongruities between different opinions still exist. This paper takes both theoretical and empirical approaches to provide a systematic answer to this question. Firstly, this paper uses industry-level gravity model of international trade to demonstrate that not all countries are negatively affected by geographical remoteness. Secondly, it employs a panel data of 83 countries from 2000 to 2017 and substantiates that while geographical remoteness decreases income levels and trade balances in OECD countries, it increases or does not affect them in non-OECD countries. This finding is also confirmed by recategorizing the countries based on the World Bank’s classification of high-income country and by carrying out quantile regressions. These results altogether imply that geographical remoteness is unlikely to be an economic disadvantage for certain groups of countries.
The Effects of Offshoring on U.S. Workers: A Review of the Literature

Recent economic literature views offshoring through the lens of a “trade in tasks” framework. Sources have used this framework to examine four main issues related to offshoring: (1) the relative price, productivity, and net effect of offshoring; (2) the different effects of offshoring for highand low-skilled workers; (3) the different types of offshoring; and (4) the relative importance of offshoring and technological change. Studies tend to find that low-skill workers are harmed by offshoring, while high-skill workers benefit. Similarly, different types of offshoring have either positive or negative impacts on employment in the home country. As a result of this heterogeneity, when discussing offshoring, economists should be clear about the effects and type of offshoring which they are discussing.
Determinants of use of electronic information resources by the professoriate in Nigerian universities: Extending the unified theory of acceptance and utilisation of technology model

Background: This study examined the determinants of use of electronic resources by the professoriate in the social sciences and humanities departments of three universities in Nigeria. The constructs of the unified theory of acceptance and utilisation of technology (UTAUT), namely, performance expectancy, effort expectancy, social influence and facilitating conditions, were used as determinants, and were extended to include self-efficacy, attitude and anxiety because of their theoretical and practical significance in the context of this study. Objectives: This study examined the determinants of the use of electronic information resources by the professoriate in the social sciences and humanities departments of three federal universities in Nigeria. Method: This study used a descriptive survey to study the determinants of use of electronic information resources by the professoriate. An adapted questionnaire was used to collect quantitative data from 246 professors from the three universities. Data were analysed with descriptive and inferential statistics using the Statistical Package for Social Sciences (SPSS). Results: The results show that performance expectancy, effort expectancy, attitude and social influence significantly influenced the professoriate’s intention to use electronic resources in comparison to self-efficacy, anxiety and facilitating conditions. The descriptive statistics, however, revealed high self-efficacy and low anxiety means scores, and showed the significance of these constructs in extending the UTAUT model within the context of this study. Conclusion: Extending the UTAUT in the academic context shows the relevance of these constructs in improving information services to the professoriates as a unique group.
CONFIRMATION OF THE DIMENSIONAL STRUCTURE

The dimensional structure of the SCL-90, a multidimensional self-report symptom inventory, was subjected to a con6rmatory empirical test with a sample of 1,002 psychiatric outpatients. A variation of factor analytic method termed a “Procrustes procedure” was utilized to compare the hypothesized nine-dimensional clinical-rational structure with the dimensional structure developed empirically. The hpothetical vs. empirical match was judged to be very good for eight of the nine hmensions, and moderate on the ninth and thereby makes a substantive contribution to the construct validity of the instrument.
Stable Isotope-Assisted Metabolomics for Deciphering Xenobiotic Metabolism in Mammalian Cell Culture

Xenobiotics are ubiquitous in the environment and modified in the human body by phase I and II metabolism. Liquid chromatography coupled to high resolution mass spectrometry is a powerful tool to investigate these biotransformation products. We present a workflow based on stable isotope-assisted metabolomics and the bioinformatics tool MetExtract II for deciphering xenobiotic metabolites produced by human cells. Its potential was demonstrated by the investigation of the metabolism of deoxynivalenol (DON), an abundant food contaminant, in a liver carcinoma cell line (HepG2) and a model for colon carcinoma (HT29). Detected known metabolites included DON-3-sulfate, DON-10-sulfonate 2, and DON-10-glutathione as well as DON-cysteine. Conjugation with amino acids and an antibiotic was confirmed for the first time. The approach allows the untargeted elucidation of human xenobiotic products in tissue culture. It may be applied to other fields of research including drug metabolism, personalized medicine, exposome research, and systems biology to better understand the relevance of in vitro experiments.
Modeling Statistical Variability with the Impedance Field Method A systematic comparison between the Impedance Field and the “Atomistic” Method

— As the transistor scaling continues, self-averaging of device properties for individual devices becomes less effective and thus the statistical variability of device properties become more prominent. Here we present the impedance field method (IFM) for statistical variability analysis, which provides a fast, convenient and accurate alternative to “atomistic” approaches and compare the two methods with respect to accuracy, calibration requirements and turn-around time.
Simulation of Turbulent Flow and Heat Transfer

In this paper, a numerical study of the turbulent air flow and heat transfer through a duct with baffle plates is performed. The effect of baffles arrangement baffles number, baffle height and baffle thickness on the flow and heat transfer characteristics is investigated. The fully elliptic differential equations that describe the flow and heat transfer are integrated using the finite volume approach. The standard k-є model with wall functions has been submitted to model the turbulence. The obtained computed results show that the boundary layer separation and recirculation regions are significantly affected with the height, thickness and arrangements of the baffle plates. Also the results demonstrate that in the presence of the baffle, the heat is significantly enhanced. The bulk temperature values along the duct are decreased with the increase of Reynolds number for all the studied cases. خلا ـ صلا ــــ ـــ ة ىلع يوتحٌ ًئاوه ىرجم لخاد ةرارحلا لاقتناو ًبارطضلاا ناٌرجلل ةٌددع ةسارد تٌرجأ ثحبلا اذه ًف ىلع اهكمسو ةحٌفصلا لوطو حئافصلا نٌب ةفاسملا ،حئافصلا ددع ،حئافصلا بٌترت رٌثأت ةسارد مت . ةقاعإ حئافص تلاداعملا ةسارد مت . ةرارحلا لاقتناو ًبارطضلاا ناٌرجلا صئاصخ ةرارحلا لاقتناو ناٌرجلا فصت ًتلا ةٌلضافتلا جذومن مادحتسأب بارطضلاا رٌثأت جلوع. ددحملا مجحلا بولسإ مادحتسأب ( k-є ) رادجلا ةلاد عم . ةساردلا هذه نم ةلصحتسملا جئاتنلا تنٌب ةروصب ترثأت دق رٌودتلا ةداعإ قطانمو ةمخاتملا ةقبطلا لاصفنا نأ مس ،ةحٌفصلا عافتراب ةظوحلم هذه دوجو عم دادزا دق ةرارحلا لاقتنا نإ جئاتنلا تنٌب امك . حئافصلا بٌترتو ةحٌفصلا ك اضٌأ . حئافصلا . زدلونٌر مقر ةداٌز عم تلق دق ىرجملا لوط ىلع ةرارحلا ةجرد طسوتم مٌق نأ ظحول Asst.

WHO EMRO | The status of serum vitamin D in the population of the United Arab Emirates

Research exploring the status of serum vitamin D levels in the populations of countries bordering the Arabian Gulf shows a high prevalence of vitamin D deficiency/insufficiency. These reports were usually drawn from small samples unlikely to be representative of the population. We explored serum vitamin D level in a large sample (7924) of patients who were given a blood test to check their vitamin D status on their first consultation at a day surgery hospital in Dubai. The overall mean level of 25(OH) D was ~ 20 ng/mL Deficiency was found among all age groups, in both sexes and in both local and non-local populations: overall 85.4% were vitamin D deficient, 12.5% showed insufficient serum vitamin D level, and only 2.1% had an appropriate level. In the multivariate model, serum vitamin D concentrations were positively correlated with male sex, local population and the 17−31 years age group.

Computing and Visualizing Precision-Recall Curves and Receiver Operating Characteristic Curves for Soft-labeled and Hard-labeled Data

The assessment of classifier performance is of fundamental importance in many bioinformatics applications. For instance, measures of classification performance are used to select appropriate models for solving classification problems. Performance evaluation is also inevitable for demonstrating the utility of novel approaches. In general, it assists researchers in identifying the most promising approach for the classification problem at hand. This implies that the choice of appropriate performance measures may influence the results of downstream analyses.
Refusal Strategies of Saudi EFL Undergraduate Students

This study aimed to explore the refusal strategies used by Saudi English as a foreign language (EFL) undergraduate students as well as to examine the relationship of these strategies to social status in the situations of request, invitation, offer, and suggestion. It provided an answer to the research question, what are the strategies used by EFL undergraduate students when performing the speech act of refusal and whether these strategies vary according to status in the situations of request, invitation, offer, and suggestion? The participants were 150 Saudi EFL students. Data were derived using a discourse completion task. It was composed of three request situations, three invitation situations, three offer situations, and three suggestion situations. Each of those situations consisted of a refusal to a person of a higher status, another one for a person of equal status, and finally one for a person of a lower status. Beebe et al. (1990) taxonomy was selected as the most comprehensive one for the analysis of refusal strategies. The results indicated that the most popular refusal strategies the participants used were the indirect ones, followed by the direct ones and then by adjuncts. The results also revealed that the participants refused differently in each of the four types of situations. On the other hand, the results showed that social status has no significant influence on their use of refusal strategies. Based on these findings, some recommendations for the integration of pragmatic teaching were suggested to foster pragmatic competence among undergraduate students.
Induction of lactation: an economic study of tool for dairy heifers with successive reproductive failures

ABSTRACT: The aim of this study was to evaluate the economic viability of the use of a lactation induction protocol in Holstein heifers. Were collected data of nutritional, reproductive and sanitary management pre and post-lactation period from 30 induction heifers (IG) and 30 pregnant heifers (CG). All animals were inseminated around 14 months of age and started lactation at 23±4 months. The animals of IG were heifers do not pregnant after two inseminations and natural service e were induced to lactation according to protocol: from the 1st to the 8th day, 30 mg of estradiol benzoate were administered daily, together with 300 mg of progesterone. From the 9th until the 14th, animals only received daily doses of 20 mg estradiol benzoate. On 16th day, 0.56 mg of sodium cloprostenol was administered and injections of 40 mg of dexamethasone sodium phosphate were administered daily from the 19th to the 21st day. On the 1st, 8th, 15th and 22nd day, the animals received a dose of sometribove zinc. The animals of CG were managed according to the farm routine. The costs of the CG during pre and post lactation (nutrition, sanitary, reproduction management) e were higher than the IG, however, when evaluating the economic viability due to lower milk production, the induced group did not leave profit in the first year of use. When comparing the lactation induction with the sale of animals that did not conceive and purchase of animals for replacement, this last scenario showed itself as a better alternative.
