Sentiment Analysis in Tickets for IT Support

Sentiment analysis has been adopted in software engineeringfor problems such as software usability and sentimentof developers in open-source projects. This paper proposesa method to evaluate the sentiment contained in tickets forIT (Information Technology) support.IT tickets are broadin coverage (e.g. infrastructure, software), and involve errors,incidents, requests, etc. The main challenge is to automaticallydistinguish between factual information, whichis intrinsically negative (e.g. error description), from thesentiment embedded in the description. Our approach isto automatically create a Domain Dictionary that containsterms with sentiment in the IT context, used to filter termsin ticket for sentiment analysis. We experiment and evaluatethree approaches for calculating the polarity of terms intickets. Our study was developed using 34,895 tickets fromfive organizations, from which we randomly selected 2,333tickets to compose a Gold Standard. Our best results displayan average precision and recall of 82.83% and 88.42%, whichoutperforms the compared sentiment analysis solutions.
Evaluation of Facial Appearance in Patients with Cleft Lip and Palate by Laypeople and Professionals: A Systematic Literature Review

Objective To identify whether laypeople and professionals rate the facial appearance of patients with cleft lip and palate (CLP) similarly based on viewing full facial images. Design Several electronic databases were searched. A hand search was performed among reference lists and relevant journals. Studies that assessed the full facial appearance of patients with CLP based on two-dimensional (2D) photographs, 3D images, or clinical examination by laypeople and professionals using a visual analog scale (VAS) or a categorical rating scale were included. Two authors independently assessed articles using methodologic-quality scoring protocol. Result Eleven articles were included in qualitative synthesis, including four high-level and seven moderate-level papers. Three studies found that laypeople were more critical than professionals, three found there was no significant difference between laypeople and professionals, and five reported that professionals were more critical than laypeople when assessing facial appearance of patients with CLP. Conclusions It still remains unknown whether laypeople are more or less critical than professionals when rating facial appearance of patients with repaired CLP. Professionals are more familiar with the esthetic outcomes and difficulties of treating patients. The opposite maybe true for laypeople; this disparity between what is achievable by professionals and what is expected by laypeople may be a source of dissatisfaction in facial appearance outcome. Further well-designed studies should be carried out to address this question and the clinical significance of the difference in rating scores for patients with CLP.
Neurological Development of Children with Isolated Robin Sequence Treated with Nasopharyngeal Intubation in Early Infancy

The study assessed the neurodevelopment of children with isolated Robin sequence (IRS) and evaluated if children treated exclusively with nasopharyngeal intubation (NPI) present delay in neurological development. The prospective and cross-sectional study was conducted at the Hospital for Rehabilitation of Craniofacial Anomalies, Brazil. Children with IRS were divided into two groups according to the type of treatment in early infancy: 38 were treated with NPI (more severe cases) and 24 with postural treatment (less severe cases). Regarding interventions, children were assessed at 2 to 6 years of age using the Denver II Developmental Screening Test (Denver II) and Neurological Evolutionary Examination (NEE). According to Denver II, 73.7% in the NPI group and 79.2% in the postural group presented normal development. This result was similar to the results of different studies in the literature with typical population. Considering all areas of development, there were no significant differences in Denver II between the NPI and postural groups (P = .854). In the NPI group, 89.5% of children and 87.5% in the postural group presented normal development in NEE. Language was the most affected area, as 18.4% and 20.8% of children in NPI and postural group, respectively, presented risk for delay in the Denver II. The increased risk for delay in language area was probably due to anatomical conditions of the muscles involved in speech, and to hearing oscillations, as 47.4% in NPI group and 58.3% in postural group underwent myringotomy. IRS treated with NPI had neurological development similar to those in less severe cases. Children treated exclusively with NPI did not present delay in neurological development.
Overlapping Variance Estimators for Simulation

To estimate the variance parameter (i.e., the sum of covariances at all lags) for a steady-state simulation output process, we formulate certain statistics that are computed from overlapping batches separately and then averaged over all such batches. We form overlapping versions of the area and Cramer--von Mises estimators using the method of standardized time series. For these estimators, we establish (i) their limiting distributions as the sample size increases while the ratio of the sample size to the batch size remains fixed; and (ii) their mean-square convergence to the variance parameter as both the batch size and the ratio of the sample size to the batch size increase. Compared with their counterparts computed from nonoverlapping batches, the estimators computed from overlapping batches asymptotically achieve reduced variance while maintaining the same bias as the sample size increases; moreover, the new variance estimators usually achieve similar improvements compared with the conventional variance estimators based on nonoverlapping or overlapping batch means. In follow-up work, we present several analytical and Monte Carlo examples, and we formulate efficient procedures for computing the overlapping estimators with only order-of-sample-size effort.
Relationship between Mandibular Ramus Height and Masticatory Muscle Function in Patients with Unilateral Hemifacial Microsomia

Objective To clarify the relationship between mandibular ramus height and function of masticatory muscles in patients with hemifacial microsomia. Design Retrospective study of imaging and physiological data. Setting Images and physiological data were obtained from the records of Sapporo Medical University Hospital. Patients A total of 29 patients with hemifacial microsomia who showed Pruzansky grades I, II deformity. Main Outcome Measures Mandibular ramus height and masticatory muscle volume were evaluated with multi-detector row computed tomography. The electromyographic value was measured by the K7 Evaluation System. The hemifacial microsomia patients were classified into three groups based on the mandibular ramus height ratio of the affected and unaffected sides: group 0, > 1.00; group 1, 1.00 to 0.85; group 2, < 0.85. The Tukey-Kramer method and Games-Howell method were used to determine correlations between parameters. Results Decreased mandibular ramus height was significantly correlated with both reduced electromyographic values of the masseter muscle (P < .05) and the amount of mandibular lateral deviation at the time of maximum opening (P < .05) on the affected side. These differences were prominent in unilateral hemifacial microsomia patients classified as group 2. Conclusions Decreased mandibular ramus height may cause dysfunction of the masseter muscles but not the temporal muscle on the affected side in patients with hemifacial microsomia.
Review: Pharmacotherapy as part of a weight management programme: a UK perspective

Rates of obesity and overweight continue to rise and substantially increase the risk of morbidity and mortality from type 2 diabetes, coronary heart disease and stroke. On the other hand, a sustained weight loss of 5-10% in the obese confers marked health benefits. Current strategies for the management of obesity include lifestyle interventions and pharmacotherapy. At present, three drugs are approved for the medical management of obesity in the UK : orlistat, sibutramine and rimonabant. All three agents are efficacious in reducing body weight but by different mechanisms. Although weight loss is an important treatment outcome, a major goal of obesity management should be to improve cardiovascular and metabolic risk factors in order to reduce obesity-related morbidity and mortality. Given the similar levels of weight loss achievable with currently approved agents, treatment decisions should include careful assessment of the effects of these agents on cardiovascular and metabolic risk factors and on their long-term safety profiles.
Social Isolation Following Embryo Transfer increases Success Rates in IVF and ICSI Cycles

Background and objective: Bruce et al had shown, during1959 to 1968, that if, 24 hours after mating, a mouse belongingto a different inbred strain than the stud mouse was placed inthe cage of the female mouse, partitioned in such a way that nophysical contact of the nonstud male with the female waspossible, pregnancy was blocked. We, therefore, decided todetermine whether, by analogy with mice, isolation of womenfrom all other men except the husband, for 3 days after embryotransfer following in vitro fertilization (IVF) or intracycloplasmicsperm injection (ICSI), increases the establishment ofpregnancy.Method:We isolated randomly selected 729 women from allother men except the husband for 3 full days after embryotransfer following IVF/ICSI, and followed them to the end ofpregnancy; 1005 randomly selected women who were treatedsimilarly but not isolated served as the control group.Results:The establishment of clinical pregnancy as well as livebirths were more than 50% higher in the isolated group than inthe control.Conclusion: The social isolation as mentioned above couldsubstantially increase the success rates in IVF or ICSI. Whilethe exact mechanism of this phenomenon is yet to beunderstood, one possible explanation may be, by analogy withmice, an olfactory block to implantation.
E-learning Opens Door to the Global Community: Novice Users' Experiences of E-learning in a Somali University

E-learning has become one of the primary ways of delivering education around the globe. In Somalia, which is a country torn within and from the global community by a prolonged civil war, University of Hargeisa has in collaboration with Dalarna University in Sweden adopted, for the first time, e-learning. This study explores barriers and facilitators to e-learning usage, experienced by students in Somalia’s higher education, using the University of Hargeisa as case study. Interviews were conducted with students to explore how University of Hargeisa’s novice users perceived elearning, and what factors positively and negatively affected their e-learning experiences. The Unified Theory of Acceptance and Use of Technology (UTAUT) model was used as a framework for interpreting the results. The findings show that, in general, the students have a very positive attitude towards e-learning, and they perceived that e-learning enhanced their educational experience. The communication aspect was found to be especially important for Somali students, as it facilitated a feeling of belonging to the global community of students and scholars and alleviated the war-torn country’s isolation. However, some socio-cultural aspects of students’ communities negatively affected their e-learning experience. This study ends with recommendations based on the empirical findings to promote the use and enhance the experience of e-learning in post conflict Somali educational institutions.
High-Fat Diet Elevates Blood Pressure and Cerebrovascular Muscle Ca2+ Current

Abstract —Dietary fat contributes to the elevation of blood pressure and increases the risk of stroke and coronary artery disease. Previous observations have shown that voltage-gated Ca2+ current density is significantly increased in hypertension and can be affected by free fatty acids (FAs). We hypothesized that a diet of elevated fat level would lead to an increase in blood pressure, an elevation of L-type Ca2+ current, and an increase in saturated FA content in vascular smooth muscle cell membranes. Male Osborne-Mendel rats were fed normal rat chow or a high-fat diet (Ob/HT group) for 8 weeks. Blood pressures in the Ob/HT group increased moderately from 122.5±0.7 to 134.4±0.8 mm Hg ( P <0.05, n=26). Voltage-clamp examination of cerebral arterial cells revealed significantly elevated L-type Ca2+ current density in the Ob/HT group. Voltage-dependent inactivation of the Ob/HT L-type channels was significantly delayed. Total serum FA contents were significantly elevated in the Ob/HT group, and HPLC analyses of fractional pools of FAs from segments of abdominal aorta revealed that arachidonic acid levels were elevated in the phospholipid fraction in Ob/HT. No differences in vascular membrane cholesterol contents were noted. Plasma cholesterol was significantly elevated in portal venous and cardiac blood samples from Ob/HT rats. These findings suggest that an elevation of plasma FAs may contribute to the development of hypertension via a process involving the elevation of Ca2+ current density and an alteration of channel kinetics in the vascular smooth muscle membrane.
La salud mental en un contexto de pobreza urbana: una aproximación cualitativa

Objetivo: Bajo el postulado de que los problemas de salud mental no son ajenos a las caracteristicas del mundo en el que vive la gente, este trabajo presenta una indagacion cualitativa sobre la situacion de un pequeno conjunto de familias pobres urbanas en Mexico a finales del siglo xx, a la vez que plantea una reflexion sobre las aportaciones que pueden hacer los enfoques que se orientan a la comprension de las complejas constelaciones que dan lugar a las perturbaciones de la salud mental que prevalecen en cada contexto. Metodologia: La interpretacion que aqui se presenta se construyo a partir de un modelo psicoanalitico postkleiniano que estudia los contextos de crianza sobre la estructuracion psiquica del sujeto. El material de analisis fue recabado varios anos atras por medio de observacion directa y entrevistas en profundidad a los integrantes de veinte familias de bajo nivel de ingreso que habitaban en una zona del sur de la Ciudad de Mexico. Resultados: La observacion orientada por este modelo permitio distinguir distintos tipos de dinamica emocional en las familias participantes, asi como su influencia sobre la estructuracion y el funcionamiento psiquico de sus integrantes. Se pudo constatar tambien la baja cobertura de servicios publicos y de atencion medica para este grupo de la poblacion y, especialmente, la gran escasez de servicios preventivos
Field Evaluation of Female Attractants for Monitoring Ceratitis capitata (Diptera: Tephritidae) Under a Range of Climatic Conditions and Population Levels in Western Australia

Abstract Field trials were conducted in Western Australia to compare captures of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), in a standard male-targeted trap (Lynfield trap baited with Capilure) with a synthetic, female-targeted attractant marketed as BioLure. BioLure was also compared with other female attractants (orange ammonia, liquid protein bait) and tested in plastic McPhail, Tephri, and Lynfield traps. The possibility of using one trap to monitor female and male C. capitata populations was also tested by combining BioLure in a trap with the male attractant, Capilure. The results of these experiments show that BioLure outperformed the female-targeted system currently used for monitoring female C. capitata (liquid protein in McPhail trap). More male C. capitata were caught in the standard male-targeted trap, but more females were caught in traps baited with BioLure irrespective of trap type, climate, host tree, or population level. Combined lure traps caught equivalent total numbers of C. capitata to the standard male-targeted trap, but fewer females were captured. Tephri traps caught more flies than McPhail traps, but McPhail traps caught equivalent proportions of females. We compared the performance in commercial orchards of the standard male-targeted trap with a female-targeted trap (McPhail with BioLure). We found that the male trap detected C. capitata more often, caught more flies, triggered the economic threshold more often (66% of the time) and was more cost effective. The male-targeted trap is recommended for use on commercial orchards if cost is limiting. However, using both male and female-targeted traps increases the chance of detecting flies and triggering the economic threshold level. The synthetic female attractant is recommended for replacement of protein hydrolysate lures and may be used in either Tephri or McPhail traps.
Avaliação tecnológica em saúde: densitometria óssea e terapêuticas alternativas na osteoporose pós-menopausa

This article briefly presents the target factors and methods for summarizing evidence employed in a technological evaluation, as well as the underlying logic in their elaboration and utilization in the field of public health. The example is post-menopausal osteoporosis, analyzing the current timeliness of disseminating bone densitometry and technologies to combat osteoporosis in Brazil Available studies on the effects of the respective technologies were reviewed according to the recommended methodology in order to produce a synthesis of the scientific evidence, updated and applied in Brazil. Preliminary cost-effective analyses of different alternatives for intervention (as compared to traditional care) are presented, considering women in and around menopause and at 65 years of age. Despite the optimistic hypotheses, the incremental cost estimates per averted fracture were high, all above R$ 10,000 for any of the various intervention alternatives, as compared to a mean cost of fractures treated by traditional care estimated at less than R$ 2,000, suggesting that the implementation of any of the target alternatives in the SUS would be questionable according to both efficiency criteria in the use of resources as well as equity.
Interleukin-8—An Early Marker for Bacterial Infection

The cytokine network is activated in the pathogenetic mechanisms of septic diseases. We measured serum concentrations of interleukin-8 (IL-8) in 152 patients with septic syndrome and 25 control subjects. IL-8 concentration in patients with septic syndrome was significantly ( P <.05) higher than in controls. Serum IL-8 concentration was assayed prospectively in 6 patients undergoing chemotherapy for leukemia. Increased IL-8 concentration preceded onset of fever and elevation of C-reactive protein by 1 day. Human peripheral whole blood cells were stimulated with phorbol 12–myristate 13–acetate (PMA), lipopolysaccharide (LPS), or lipoteichoic acid. IL-8 mRNA expression was detected 10 minutes after PMA or LPS exposure, and IL-8 was secreted into culture media 3 hours after exposure. These data suggest that IL-8 is a useful early indicator of bacterial infection.
Collaborative Care for Bipolar Disorder: Part II. Impact on Clinical Outcome, Function, and Costs

Objective:The study addressed whether a collaborative model for chronic care, described in part I (this issue), improves outcome for bipolar disorder.Methods:The intervention was designed to improve outcome by enhancing patient self-management skills with group psychoeducation; providing clinician decision support with simplified practice guidelines; and improving access to care, continuity of care, and information flow via nurse care coordinators. In an effectiveness design veterans with bipolar disorder at 11 Veterans Affairs hospitals were randomly assigned to three years of care in the intervention or continued usual care. Blinded clinical and functional measures were obtained every eight weeks. Intention-to-treat analysis (N=306) with mixed-effects models addressed the hypothesis that improvements would accrue over three years, consistent with social learning theory.Results:The intervention significantly reduced weeks in affective episode, primarily mania. Broad-based improvements were demonstrated i.
Evaluation of the Eytex System for Use as a Predictor of Ocular Irritancy. I. Shampoos

AbstractThe Eytex in vitro assay was used to evaluate 42 adult and baby shampoos. The assay, which is based on protein precipitation, was chosen because it provides rapid, quantitative results at a relatively low cost. All shampoos were diluted 1:10 in deionized water and tested with two different protocols: the rapid membrane assay (RMA) protocol for adult products and the high-sensitivity assay (HSA) for baby shampoos. All samples were tested in two and, in some cases, three separate experiments and the qualified Eytex scores were averaged. The correlation of the Draize scores with the Eytex scores was statistically significant (r2 = 0.90). The Eytex scores were used to establish irritation classes similar to the standard Draize classification scheme (minimal, mild, moderate, severe). When the Draize eye irritation class was compared to the Eytex irritation class for a given shampoo, the correlation for the baby shampoo data was 100% and 89% for the adult shampoo data. This study indicates that the Eyte.
Enabling risk and ensuring safety: self-directed support and personal budgets

Purpose – This paper aims to present a digest of the main discussion points and key findings from a recent Social Care Institute for Excellence report on risk enablement and safeguarding in the context of self‐directed support and personal budgets.Design/methodology/approach – The paper explores how the personalisation agenda and adult safeguarding can work together in policy and practice and addresses some of the frontline concerns about empowerment and duty of care.Findings – Evidence on how self‐directed support and personal budgets can be used to enable people to take positive risks while staying safe and emerging practice is examined. It suggests that person‐centred working in adult safeguarding, along with the mechanism of self‐directed support planning and outcome review, can support the individual to identify the risks they want to take and those they want to avoid in order to stay safe. It is clear that if frontline practitioners are overly occupied with protecting organisations and individuals f.
Comparison of cycloplegic retinoscopy using cyclopentolate or tropicamide eye drops in an epidemiologic study of pediatric refraction among 1907 school-aged children

Compound tropicamide eye drop (0.5% tropicamide + sodium hyaluronate) and 1% cyclopentolate eye drop were compared in an epidemiologic study of pediatric refraction in school-aged children. A total of 1907 school-aged children were divided into three age groups: 6 to 8, 9 to 12, and 13 to 15 years old. Compound tropicamide eye drop and 1% cyclopentolate eye drop were used in the same individual before conducting retinoscopy, sequentially. The administration protocols were as follows. Three drops of compound tropicamide eye drop were administrated (one drop every 10 min), followed by retinoscopy 30 to 45 min later. Three drops of 1% cyclopentolate eye drop were administrated (one drop every 10 min), followed by retinoscopy 45 to 75 min later. There was a 7-day interval between the two times of retinoscopy. Average diopter was significantly higher using cyclopentolate than tropicamide in all age groups (p<0.001). The diopter (spherical equivalent value) < 0.50 D was considered as the coincidence rate between retinoscopies using the two different cycloplegic agents. Classified by the age group, the coincidence rate was 57.14% in 6 to 8 years old group (n=595), 67.79% in 9 to 12 years old group (n=798) and 81.70% in 13 to 15 years old group (n=514). Classified by refractive status, the coincidence rate was 94.97% (n=199) in myopia population, 79.53% in emmetropia population (n=337) and 61.56% in hyperopia population (n=1371). The cycloplegic effect of cyclopentolate was stronger than that of tropicamide. The variation was even more significant with the reduction of age and increase of diopter.
