Study of Audio – Visual Reaction Time in Chronic Smokers and Alcoholic Males

The consumption of alcohol and cigarette smoking is most common and serious problem, worldwide. Apart from various factors such as awakening, age, sex, left v/s right hand practice, number of stimuli, fasting and nutrition, reaction time is also affected by smoking and alcohol consumption. The aim of the present study is to measure and compare Auditory & Visual reaction time between study groups (smoker, alcoholic, smoker with alcoholic) and control group. The present study involves 360 subjects in the age group of 30-60 years, both smoker and alcoholic, recruited from medicine OPD from S.M. S Hospital, Jaipur (Rajasthan). Out of total 360 subjects: 90 were smoker, 90 were alcoholic, 90 were smoker with alcoholic and 90 were control subjects. Data were statistically analyzed by student’s unpaired t test, one way ANOVAs and post hoc turkey test. Visual reaction time (sec.) for red and green light increased significantly (p < 0.05) in alcoholics and smoker with alcoholics when compared with controls with left hand and with right hand visual reaction time for red and green light increased significantly (p < 0.05) in smoker with alcoholics and smokers. Further, Auditory reaction time (sec.) (for low and high pitch) is highest in smoker with alcoholic group but non-significant, for low pitch with both left and right hand. Alcohol decreases processing of information and both smoking and alcohol consumption affects audio-visual reaction time by several ways.
Antibiotic resistance and genotyping of gram-negative bacteria causing hospital-acquired infection in patients referred to Children’s Medical Center

Background and aim Hospital-acquired infection (HAI) is a major problem worldwide. Understanding patterns of bacterial etiology and antibiotic susceptibility is vital to combating HAI. Besides, typing of isolates is important to establish the intra-hospital surveillance of resistant clones. In this study, we aimed to evaluate antibiotic resistance and genotyping of a number of gram-negative bacteria (GNB) causing HAI in patients who were referred to Children’s Medical Center. Methods During the 6-month period, antimicrobial susceptibility profiles of GNB isolates recovered from patients in Children’s Medical Center were determined. Typing of common GNB was performed by random amplified polymorphic DNA (RAPD) analysis and the results were analyzed by Gelcompar II software. Results In total, 142 (1.1%) gram-negative bacterial strains were isolated, among which 59.2% were from males. The most organisms were isolated from blood (63%) followed by wounds (13.7%). The greatest proportion of strains came from intensive care units (51%). Low sensitivity of Acinetobacter baumannii to common antibiotics and high resistance of Enterobacter spp. To cefotaxime (100%) were reported. The most efficient antibiotics for Escherichia coli strains were amikacin (84%) and gentamycin (81%). However, just 12.5% of Serratia marcescens strains were resistant to trimethoprim-sulfamethoxazole. The analysis of RAPD-typing revealed the presence of one clone in A. baumannii and E. coli and two clones in Klebsiella pneumoniae, whereas the trend varied completely in Pseudomonas aeruginosa strains and Enterobacter spp. Conclusion The results of this study showed a possibility of an outbreak in the Children’s Medical Center. Since there is a possibility of transmission of an infection from one patient to another, high attention should be paid to the basic methods of preventing infection.
Shoulder proprioception in male adolescent tennis players and controls: The effect of shoulder position and dominance

Proprioceptive information appears to play an important role in stability and movements of shoulder joint in sporting activities especially in tennis. The purpose of this study was to measure the shoulder proprioceptive sense differences between male tennis players and control group, in sitting and standing positions. 15 young male tennis players with a mean age 14.6 ± 0.7 years and 15 young male sedentary individuals with a mean age 14.8 ± 0.9 years participated in this cross-sectional descriptive study. Proprioceptive sense was measured with an isokinetic dynamometer. Measurements were made in two positions: 'sitting' versus 'standing' for forehand and backhand positions. Service motion was measured in sitting position. There was no statistical difference between players and non-players in means of age, body height, weight, and BMI. The study revealed the following results: 1) there was a significant difference between shoulder proprioceptive senses of players and controls (p < 0.05). 2) significant difference between dominant and non-dominant shoulders at 15° and 30° was not observed (p < 0.05). 3) no significant difference was observed between sitting and standing positions at 30° (p < 0.05). It was concluded that tennis players had better proprioceptive sense than their age matched sedentary controls.
Zootaxa, Cirripedia, Acrothoracica

The morphology of the females and males of the ancient acrothoracican burrowing barnacle family, the Lithoglpytidae Aurivillius, 1892, was surveyed. It became evident that by resurrecting a previously described family-group taxon and proposing a new family-group taxon, the Lithoglyptidae could readily be divided into three subfamilies, the Lithoglyptinae s.s. Aurivillius, 1892 stat. nov., the Weltneriinae subfam. nov., and the Kochlorininae Gruvel, 1905 stat. nov. The largest and relatively generalized lithoglyptine genus, Lithoglyptes s.l. , was investigated utilizing SEM as well as conventional means. From gross morphological characteristics it became evident these species fell into three natural groups for which we propose the genera Lithoglyptes s.s. , Auritoglyptes gen. nov., and Armatoglyptes gen. nov. The relationships between the species as well as the genera are explored cladistically, a new species of Armatoglyptes is described from Bermuda, the biogeography of the subfamily is discussed, and a key to the genera and species is provided.
On the number of variables to use in principal component regression

We study least squares linear regression over N uncorrelated Gaussian features that are selected in order of decreasing variance. When the number of selected features p is at most the sample size n, the estimator under consideration coincides with the principal component regression estimator; when p > n, the estimator is the least ` 2 norm solution over the selected features. We give an average-case analysis of the out-of-sample prediction error as p, n, N ! 1 with p/N ! ↵ and n/N ! , for some constants ↵ 2 [0, 1] and 2 (0, 1). In this average-case setting, the prediction error exhibits a “double descent” shape as a function of p. We also establish conditions under which the minimum risk is achieved in the interpolating (p > n) regime.
Victorian family day care scheme providers' knowledge of child restraint best practice

In Victoria nearly half of the population under 12 years of age uses family day care services. Providers of family day care services are in a position to provide important information on the best practice of child transportation to family day care educators, and families accessing family day care. Our study, conducted in November 2011, aimed to investigate family day care service providersr level of knowledge of best practice for transporting children in cars. A sample of Family Day Care Victoria service providers completed a survey on child restraint knowledge, practices and attitudes. Of the providers surveyed, 98 per cent stated that they knew the law regarding child restraint usage. A high proportion offered professional and practical support (92 per cent) as well as educational resources (94 per cent) to family day care educators with regards to safe transportation. However, when asked to provide the minimum age at which children are able to use a specific restraint type only 81 per cent correctly identified the minimum age for booster seats, 75 per cent for forward-facing restraints, 40 per cent for the front seat, and 58 per cent for adult seat belts. These results indicate that more effort is required to support family day care services, which are required to ensure that transport is suitable and safe for all children. Family day care services act as information conduits to families with young children, and additionally educate and train family day care educators travelling daily with young children in their charge. This would ensure all children are provided optimal levels of protection whenever they travel in cars.
Social sustainability in supply chains: clarifications and insights Sustentabilidade social na cadeia de suprimentos: esclarecimentos e novas direções

Considering a historical predominance of environmental issues within the context of sustainability, social issues are underrepresented. This also appliesfor Sustainable Supply Chain Management. The research field still advances disproportionately on environmental and economic dimensions, front of the social dimension. This study aims toshed additional light about sustainable supply chain management, focusing on provide a theoretical explanation for social sustainability adoption into the supply chain. To guide this theoretical essay, the studyexplores theconcepts of social issues and governance mechanisms and presents a framework for social sustainability adoption and management into supply chains, considering three guiding theories: Stakeholder Theory, Behavioral Theory and Contingency Theory. In order to collaborate with a future research agenda for the field, research gaps focusing on the social dimension are addressed.
EFFECT OF ANTIOXIDANT SUPPLEMENTATION IN DIETS OF ROOSTERS DURING THE POST-PEAK PHASE ON REPRODUCTION AND PRODUCTION CHARACTERISTICS OF OFFSPRING

Abstract This study aimed to evaluate the effects of antioxidant supplementation in diets of breeding roosters during the post-peak phase on reproduction characteristics and muscle performance of offspring in two similar breeder houses from a local company. Treatments consisted of a control diet and a diet supplemented with antioxidants (8 ppm canthaxanthin + 40 ppm lycopene + 150 ppm vitamin C). During the 66th week of age, eggs were incubated, and offspring were housed. Dietary supplementation of the blend of antioxidant resulted in higher (p<0.05) weights of testicles, crests, dewlaps, dewlap thickness, and number of perforations (53.35 x 25.30) in relation to non-supplemented roosters. There was no significant effect (p>0.05) of supplementation of the antioxidant blend on weight gain and breast weight and count and diameter of muscle fibers of offspring at 7 days of age. Feed conversion and weight gain from 14 to 35 days were better (p<0.05) in offspring from supplemented roosters. The supplementation of an antioxidant blend in roosters improved reproductive characteristics assessed and feed conversion and weight gain of offspring.
A Socio-Epidemiological Study Of Leprosy In A Leprosy Endemic Rural Population (South India)

Various social factors in relation to leprosy were studied in a rural population of Pondicherry Union Territory. The prevalence of leprosy among Harijans was found to be 56.8 / 1000 and among Gounders it was 40.08 / 1000. Highest prevalence of 46.05 / 1000 was found in those whose income was between Rs.100/- and 200/- per month. The prevalence of leprosy was inversely correlated with the education. A positive history of contact was forthcoming in 30.1% of the cases. Only 23.6% of the cases were registered for treatment was 6.30%. There was a change in the social life in 2.09% of the cases and the income had decreased in 3.14% of the cases consequent to the disease.
Time variability and uncertainty in the fraction of young water in a small headwater catchment

Abstract. The time precipitation needs to travel through a catchment to its outlet is an important descriptor of a catchment's susceptibility to pollutant contamination, nutrient loss, and hydrological functioning. The fast component of total water flow can be estimated by the fraction of young water (Fyw), which is the percentage of streamflow younger than 3 months. Fyw is calculated by comparing the amplitudes of sine waves fitted to seasonal precipitation and streamflow tracer signals. This is usually done for the complete tracer time series available, neglecting annual differences in the amplitudes of longer time series. Considering inter-annual amplitude differences, we employed a moving time window of 1 year in weekly time steps over a 4.5-year δ18O tracer time series to calculate 189 Fyw estimates and their uncertainty. They were then tested against the following null hypotheses: (1) at least 90 % of Fyw results do not deviate more than ±0.04 (4 %) from the mean of all Fyw results, indicating long-term invariance. Larger deviations would indicate changes in the relative contribution of different flow paths; (2) for any 4-week window, Fyw does not change more than ±0.04, indicating short-term invariance. Larger deviations would indicate a high sensitivity of Fyw to a 1-week to 4-week shift in the start of a 1-year sampling campaign; (3) the Fyw results of 1-year sampling campaigns started in a given calendar month do not change more than ±0.04, indicating seasonal invariance. In our study, all three null hypotheses were rejected. Thus, the Fyw results were time-variable, showed variability in the chosen sampling time, and had no pronounced seasonality. We furthermore found evidence that the 2015 European heat wave and including two winters into a 1-year sampling campaign increased the uncertainty of Fyw. Based on an increase in Fyw uncertainty when the mean adjusted R2 was below 0.2, we recommend further investigations into the dependence of Fyw and its uncertainty to goodness-of-fit measures. Furthermore, while investigated individual meteorological factors did not sufficiently explain variations of Fyw, the runoff coefficient showed a moderate negative correlation of r=-0.50 with Fyw. The results of this study suggest that care must be taken when comparing Fyw of catchments that were based on different calculation periods and that the influence of extreme events and snow must be considered.
PARTIAL CHARACTERIZATION OF BACTERIOCINS PRODUCED BY TWO STRAINS OF LACTIC ACID BACTERIA, ISOLATED FROM TRADITIONAL EGYPTIAN DAIRY PRODUCTS

This study presents the characterization of strains of lactic acid bacteria (LAB) from traditional Egyptian dairy products. 623 isolates of lactic acid bacteria (LAB) were studied for their antimicrobial activity against taxonomically related microorganisms. Selected LAB were identified by PCR method as Enterococcus faecium IM1and Enterococcus hirae IM1. Partial purified enterocin from tested strains showed antimicrobial activity against different indicators such as: Brochothrix thermosphacta DSMZ, Carnobacterium maltaromaticum CIP103135 T , Carnobacterium piscicola S4312, Enterococcus faecalis JH2, Listeria grayi CLIP12518, Listeria innocua, Listeria ivanovii ATCC, Listeria monocytogenes and Vagococcus penaei CIP109914 T but have no effect against Bacillus subtilis, Moellerella wisconsensis, Pseudomonas fluorescens, Salmonella enterica, Salmonella montevideo, Salmonella typhimurium and Serratia liquefaciens CIP103238 T . The inhibitory activity was not due to hydrogen peroxide for Enterococcus hirae IM1, but strain Enterococcus faecium IM1 may excrete diverse antimicrobial compounds such as hydrogen peroxide and bacteriocins. Bacteriocins produced by isolated strains were stable between pH 5 and 8 and stable until 100°C/ 20 min. Tested strains were free from some of virulence determinant genes. They may be useful as starter cultures and co-cultures. Consequently, the selected strains can be applied in fermented dairy foods as efficient biopreservatives cultures.
Measurement of Shoulder and Trunk Movements in Hemiplegic Participants Using a System for Collecting Motion Data

Upper limb and trunk functionalities are important for performing activities of daily living, such as eating, drinking, clothing and personal care. However, hemiplegic patients impair upper extremity functionalities, the activities are performed by using compensatory movement strategies. Recently, Takahashi and Murata et al. developed a system for collecting motion data with a cloud service. The purpose of this study was to investigated whether clinical application of this system for collecting motion data is available as assessment for hemiplegic patients. Two hemiplegic participants and one healthy participant performed drinking task, and the angles of shoulder abduction and trunk flexion were calculated. Angles of shoulder abduction and trunk flexion during drinking between non-paretic and healthy sides were similar, however, the larger angles of shoulder abduction and trunk flexion during drinking by paretic side showed compared with them by non-paretic and healthy sides. We believe that this system will be available as a quantitative assessment of activities of daily living in patients with disabilities. Keywords-rehabilitation treatment; activities of daily living; disability; functional recovery.
School motivation, goal orientation and academic performance in secondary education students

Background: In the students' school stage can appear many psychological variables that can positively or negatively affect the academic life of the students as well as their learning process. Therefore, the present study aims to explore the relation between school motivation, goal orientation and academic performance in adolescent students. Methods: This cross-sectional study was performed on adolescent students (N=3512) from 18 public Secondary Education (ESO) centers. The Scale of School Motivation (EME-S), the Perception of Success Questionnaire (POSQ) and academic performance, quanti ﬁ ed by each student ’ s mean mark, were instruments used. Results: The results revealed signi ﬁ cant relations among, on the one hand, intrinsic school motivations, task-oriented goal orientations and academic performance in a more adaptive pattern behavior and, on the other hand, relations between extrinsic motivations and ego-oriented goal orientations. The in ﬂ uence of intrinsic motivations, task-oriented goal orientations and low amotivation indices on predicting academic performance was deduced. Conclusion: The importance of promoting adaptive behaviors that improve adolescent students ’ academic lives focus on adequate levels of school motivation and task-oriented goal orientations at their education centers was revealed.
Endogenous selection into single and coauthorships by surnames in economics and management

Many prior studies suggest that alphabetic ordering confers professional advantages to authors with earlier surname initials. However, these assume that authors are select into coauthorships, without regard to the incentives identified. We consider the alternative and develop a model of endogenous selection into single and coauthorships for economics and tested it using management as a benchmark. We predict that lower citation ranked (“ability”) authors with earlier surnames would be less desirable as coauthors, while higher ability authors with later surnames would have a lower desire to coauthor. Both are therefore more likely to single author. Furthermore, higher ability authors with earlier surnames should have more and better coauthoring options, all the more so, for authors of non-alphabetically ordered papers. Consistent with our predictions, we found citation ranks were increasing on surnames for single authored works and decreasing for coauthored in economics both absolutely and compared to management, and that the effect was even more severe for non-alphabetically ordered papers. We show that economists take into account both the likely contribution of their coauthors and their own share of the credit, when deciding to coauthor, and thus, offer an alternative explanation for prior findings. We also show that the alphabetical convention could have important consequences for research productivity.
The Determinants of the Stock Price Performance of Analyst Recommendations

This study examines the cross-sectional determinants of the price reaction to analysts’ recommendations disseminated through various type of media and for firms listed in Taiwan stock markets. We measure abnormal returns using the market model of event study. Based on the type of media (traditional media/social media) and the type of exchange (Taiwan Stock Exchange (TWSE)/Taipei Exchange (TPEx)), we classify the combined sample observations into four samples and run quantile regressions to investigate whether the relation will be uniform across various quantile levels. Our results show that the relation between firm characteristics and cumulative abnormal returns is not homogeneous across various quantiles of abnormal returns. Our evidence indicates that in general the relation tends to be stronger for firms at higher performance quantile levels and tends to be more pronounced for TWSE firms. The strongest relation is found for the Traditional/TWSE sample, where the abnormal returns are positively related to insider ownership and prior-period earnings, and negatively related to institutional shareholding and price-to-book ratio for firms in the highest abnormal performance quantile.
Characterizing Android App Signing Issues

In the app releasing process, Android requires all apps to be digitally signed with a certificate before distribution. Android uses this certificate to identify the author and ensure the integrity of an app. However, a number of signature issues have been reported recently, threatening the security and privacy of Android apps. In this paper, we present the first large-scale systematic measurement study on issues related to Android app signatures. We first create a taxonomy covering four types of app signing issues (21 anti-patterns in total), including vulnerabilities, potential attacks, release bugs and compatibility issues. Then we developed an automated tool to characterize signature-related issues in over 5 million app items (3 million distinct apks) crawled from Google Play and 24 alternative Android app markets. Our empirical findings suggest that although Google has introduced apk-level signing schemes (V2 and V3) to overcome some of the known security issues, more than 93% of the apps still use only the JAR signing scheme (V1), which poses great security threats. Besides, we also revealed that 7% to 45% of the apps in the 25 studied markets have been found containing at least one signing issue, while a large number of apps have been exposed to security vulnerabilities, attacks and compatibility issues. Among them a considerable number of apps we identified are popular apps with millions of downloads. Finally, our evolution analysis suggested that most of the issues were not mitigated after a considerable amount of time across markets. The results shed light on the emergency for detecting and repairing the app signing issues.
