Histological and Histochemical study of the Esophagus in Laughing Dove Streptopelia senegalensis

The present study represent the histological and histochemical structure of the esophagus of laughing dove Streptopelia senegalensis, one of the wild birds, which feed on the seeds( grainvorous). The result showed that the esophagus long tubular quit wide and highly distensible organ situated at the right side of the nick , lie between pharynx and stomach it was divided into cervical and thoracic part , the cervical part longer than the thoracic part, and the crop was merely enlargement fusiform in shape which located at the entrance of the thorax. Esophagus parts showed that composed of four layer ;the mucosa, sub mucosa, muscular and adventitia or serosa, the mucosal layer was arranged in folds which was longer in the cervical part and constituted by nonkertenized stratified squamous epithelium ,the lamina propria had esophageal glands in the the thoracic part only . The submucosa composed of a thin layer of connective tissue , muscularis externa consists of two layers of smooth muscle fibers, which were an inner circular layer and an outer longitudinal layer which was surrounded by adventitia or serosa . The histochemical result showed the glands positive reaction with (PAS) dye and the mucous layer of the wall of the esophagus showed positive with Alcian blue -PAS dye as well as with Mercuric bromophenol blue dye, esophageal glands did not show a positive reaction with the last dye.
Competitive intelligence in hospitality and tourism: a perspective article

This study aims to critically review competitive intelligence (CI) research and offer suggestions for future research in the hospitality and tourism (HT) field. ,The study reviews and synthetizes current CI research in the HT field. ,The study findings suggest that CI research in HT is at an embryonic level, as researchers have not used the same terminology on what CI is, how CI is implemented and what should be included in the CI framework. Hence, researchers should address the link between operation and CI practices. Also, new studies discussing business espionage and ethics in CI practices are needed because the related studies are rare. ,The study offers specific theoretical and practical implications for CI research. ,This study provides a perspective on future developments of CI research in the HT field.
Conserved and divergent features of DNA methylation in embryonic stem cell-derived neurons

DNA methylation functions in genome regulation and is implicated in neuronal maturation. Early post-natal accumulation of atypical non-CG methylation (mCH) occurs in neurons of mice and humans, but its precise function remains unknown. Here we investigate mCH deposition in neurons derived from mouse ES-cells in vitro and in cultured primary mouse neurons. We find that both acquire comparable levels of mCH over a similar period as in vivo. In vitro mCH deposition occurs concurrently with a transient increase in Dnmt3a expression, is preceded by expression of the post-mitotic neuronal marker Rbfox3 (NeuN) and is enriched at the nuclear lamina. Despite these similarities, whole genome bisulfite sequencing reveals that mCH patterning in mESC-derived neurons partially differs from in vivo. mESC-derived neurons therefore represent a valuable model system for analyzing the mechanisms and functional consequences of correct and aberrantly deposited CG and non-CG methylation in neuronal maturation.
Aerobic Dance Wore with EMS Suit Improves Fatness and Biomarkers of Obese Elderly Women

Electromyostimulation (EMS) has been shown to improve body composition, but what biomarkers it affects has not been investigated. The purpose of this study was to compare the EMSeffect of aerobic dance on fatness and biomarkers’ levels in obese elderly women. Methods: Twentyfive women with obesity were randomly classified into a control group (CON; n = 12) and EMS group (EMSG; n = 13). EMS suits used in this study enabled the simultaneous activation of eight muscles with selectable intensities. Program sessions of EMS were combined with aerobic dance three times a week for 8 weeks. Although both groups received the same program, CON did not receive electrical stimuli. Results: Compared with CON, a significant effect of the EMS intervention concerning decreased fatness, as well as an increased skeletal muscle mass and basal metabolic rate, were evident. Compared with CON, aerobic dancing with an EMS suit also improved biomarkers in EMSG. Cytokines, including interleukin-6, tumor necrosis factor, C-reactive protein, resistin, and carcinoembryonic antigen were significantly changed in EMSG, whereas those of CON did not change from the baseline to the end of the experiment. These results showed significant differences between groups. Similarly, the changes caused by EMS were represented in high-density lipoproteincholesterol and low-density lipoprotein-cholesterol. Conclusions: The results indicate that a significant effect due to the EMS intervention was found concerning body composition and biomarkers in obese elderly women.

Seroprevalence Studies on Brucellosis in Goats of Jammu Region

A study on brucellosis in goats from 10 different parts of Jammu region was conducted from 2011 to 2013. A total of 724 serum samples was collected and subjected to Rose Bengal plate test (RBPT), modified-Rose Bengal plate test (m-RBPT), standard tube agglutination test (STAT) and indirect-enzyme-linked immunosorbent assay (I-ELISA). The overall seroprevalence was 7.73 (RBPT), 8.29 (m-RBPT), 10.22 (STAT) and 12.98% (I-ELISA) based on individual test. Ffemales, goats from unorganized rearing and older goats were found most vulnerable. The sensitivity of m-RBPT and kappa value as well as specificity of RBPT were found best for the diagnosis of brucellosis in goats. Among serological tests, I-ELISA was found most sensitive and detected maximum number of positive sera samples.
Board, audit committee, ownership and financial performance – emerging trends from Thailand

This study aims to investigate the effects of corporate board and audit committee characteristics and ownership structures on market-based financial performance of listed firms in Thailand. ,It applies system GMM (generalized method of moments) as the baseline estimator approach, and ordinary least squares and fixed effects for robustness checks on a sample of 452 firms listed on the Thai Stock Exchange for the period 2000-2016. ,Relying mainly on the system GMM estimator, the empirical results indicate some emerging trends in the Thai economy. Contrary to expectations for an emerging market and prior research findings, ownership structures, particularly ownership concentration and family ownership, appear to have no significant influence on market-based firm performance, while managerial ownership exerts a positive effect on performance. Moreover, as expected, board structure variables such as board independence; size; meeting and dual role; and audit committee meeting show significant explanatory power on market-based firm performance in Thai firms. ,These findings are important for policymakers in constructing an appropriate set of governance mechanisms in an emerging market context, and for corporate entities and investors in shaping their understanding of corporate governance in the Thai institutional context. ,Unlike previous literature on the Thai market, this study is the first to use the more advanced econometric method known as system GMM estimator for addressing causality/endogeneity issues in governance–performance relationships. The findings indicate new trends in the explanatory power of ownership structure variables on market-based firm performance in Thai-listed firms.
Credit Union and Bank Subprime Lending in the Great Recession

Firm structure affects incentives and performance. We document significant differences in subprime lending between banks and credit unions prior to and during the Great Recession. In 2006, 23.6% of mortgages from commercial banks were subprime versus only 3.6% of mortgages from credit unions. Moreover, banks were more likely to fail, and had higher delinquency and net charge-off ratios immediately following the financial crisis. Our empirical models control for important differences between credit unions and banks including firm-level characteristics, borrower-level characteristics, and state-level economic conditions. We argue that the remaining difference captures the effects of credit unions’ nonprofit and cooperative structure, which encourages them to internalize the utility of their customer-owners. Our findings explain why credit unions often appear more risk averse relative to commercial banks, a result with important research and policy implications.

Polarized education levels and civil unrest

After introducing a measure for educational polarization (EduPol), this paper presents a theoretical framework to understand whether and how EduPol may affect the contest for power in society. The model suggests that societies with high degrees of EduPol (i.e., substantial shares with either no or university-level education) are systematically more prone to civil unrest. We test this prediction on four measures of civil unrest: Political instability, domestic terrorism, civil conflict, and civil war. Our empirical estimations produce evidence consistent with this hypothesis as all four phenomena are positively associated with EduPol at the beginning of the respective period, exhibiting meaningful magnitudes. These results prevail when accounting for (i) potentially confounding factors, (ii) country- and time- fixed effects, (iii) economic inequality, (iv) ethnic and religious polarization and fractionalization, and (v) numerous alternative estimations and outcome variables.
Seroprevalence of HIV in ANC clinic attendees and utilization of PPTCT services at a tertiary care hospital of western Rajasthan, India

Background: Human immunodeficiency virus (HIV) infection in pregnant women has an important role in its spread to paediatric population by means of vertical transmission. Effective utilization of PPTCT services can reduce this spread. This study aims to determine seroprevalence of HIV in antenatal women, demographic factors of seropositive women and utilization of PPTCT services to minimize the risk of mother to child transmission. Methods: A retrospective study was done among pregnant women attending antenatal clinic of a tertiary care hospital within a period of two years from November 2013 to October 2015. Pre-test counselling, HIV testing, and post-test counselling were done as per NACO guidelines. Antiretroviral prophylaxis was given to seropositive women and their children. Analysis of demographic data of seropositive women and assessment of utilization of PPTCT services was done. Results: Out of 40,913 new antenatal registrations 26,803 (65.58%) women attended pre test counselling and 24716(60.41%) of them accepted HIV testing. Thirty-eight women were found to be seropositive with a seroprevalence rate of 0.16%. Majority of seropositve women were young primigravida, illiterate housewives belonging to rural area. Eight out of 33 partners of seropositive women tested, were found to be seronegative. Out of the 38 seropositive women, 4(10.52%) opted for pregnancy termination, and 31(81.57%) had delivery in our institution. All mother and baby pairs received antiretroviral prophylaxis. Conclusions: Seroprevalence of HIV infection in antenatal women is relatively low in this region than the national average and acceptance of therapeutic interventions to reduce the mother to child transmission is high. There is scope to improve acceptance of counselling and testing of HIV.
Common Errors Made in Learning English Prepositions While Writing Essays by Iraqi Students

This study examines the most important commonly errors made in learning English prepositions while writing essays by Iraqi students of English as a foreign language. It suggests some solutions to help them recover and overcome their errors. All the students come from non-English speaking background and hardly communicate in English outside school. The study was carried out at preparatory schools in Diwaniya governorate in Iraq. Seventy essays were collected from two secondary schools and analyzed in relation to the theories of Contrastive Analysis and Error Analysis. A detailed classification of the most common errors, their analysis, and the comparison of the total number of inter-lingual and intra-lingual errors are given place in this study. The study aims to find out answers to the following research questions: 1.What are the types of prepositional errors committed while writing English Essays by Iraqi final year EFL senior secondary school students? 2.What are the causes/sources of prepositional errors committed while writing English Essays by Iraqi final year EFL senior secondary school students? 3.What is the effect of Arabic language interference on learning English language prepositions as used by Iraqi final year EFL senior secondary school students in Iraq? 4.What should be the appropriate method in teaching English prepositions to Iraqi EFL senior secondary school students? This study intends to use a qualitative content analysis of the students’ written essays in accordance with the Error Analysis approach. For this, the researcher intends to explore and analyze the written productions of the final year students’ essays. Thus, the results of the study identify the kinds of prepositional errors Iraqi students commit in writing as well as their sources and causes in Dewaniyah governorate in Iraq. This study has shed light on the manner in which students internalize the rules of the target language. Such an insight into language learning problems is useful to teachers as it provides information on common troubles confronted in language learning which can be used in the preparation of effective teaching materials.

The purpose of this study was to investigate the Canonical analysis of the relationship between personality traits and attitude with motivation and EFL learners’ written production task. This research in terms of data collection procedure is a correlation type. The statistical population consisted of the students who were selected by random cluster sampling method. Data were analyzed using standard questionnaire of motivation, attitude, and personality traits, and analyzed by SPSS software using statistical tests. The results of correlation analysis of variables showed that there is a significant positive correlation between personality traits with motivation and written skills. It was also determined that attitudes with motivation and written skills predict a positive and significant relationship. Finally, the results of this study can be a very clear perspective for planners and trainers of writing skills training courses to pay more attention to non-cognitive and attitudinal variables such as personality traits and learners’ motivation in English language classes.
Job characteristics and perceived cultural novelty: exploring the consequences for expatriate academics’ job satisfaction

Abstract Drawing from the Job Characteristics Model, this study elucidates the joint effects of job autonomy and job clarity on expatriate academics’ job satisfaction and explores if the combined effects of job autonomy and job clarity vary depending on perceived cultural novelty. Based on a sample of 428 expatriate academics, we test our hypotheses using moderated polynomial regression and response surface analysis. Findings show that job satisfaction was highest when both job autonomy and job clarity were pronounced. In a situation of imbalance, higher levels of job satisfaction were found when job clarity exceeded job autonomy, indicating that job clarity is more important than job autonomy. Further, analyses provide tentative support for the moderating role of perceived cultural novelty, thus, showing that the relative importance of job clarity for job satisfaction increased/decreased when perceived cultural novelty was high/low.
A Clinical and Radiologic Study

A consecutive series of patients undergoing total knee arthroplasty (TKA) using either a mobile-bearing (MB) or a fixed-bearing (FB) implant were studied. Forty-four patients received 57 MB rotating platforms, and 40 patients received 45 FB posterior stabilized implants. At an average 41-month follow-up (range, 2-6 years), no significant differences were found between the groups with respect to Knee Society ratings or pain scores. Postoperative flexion was not different between the groups (116° for MB and 118° for FB). Three MB knees were revised for implant-related complications. There was no difference between these MB or FB knee implants clinically or radiographically at early follow-up. However, more patients with a MB knee required early revision for failure of rotating patellar or tibial polyethylene implants. Key words: range of motion, mobile-bearing, fixed- bearing, total knee arthroplasty.
Middle–late permian I-type granitoids from the Diaobingshan region in the northern margin of the North China Craton: insight into southward subduction of the Paleo–Asian Ocean

ABSTRACT An integrated study of the petrology, zircon U–Pb geochronology, whole–rock geochemistry, and in situ zircon Hf isotopic compositions of middle–late Permian granitoids from the Diaobingshan region in the northern margin of the North China Craton (NCC) has been implemented, with the aim of investigating their geochronological framework, petrogenesis, and tectonic significance. The studied granitoids are widely distributed on the southern side of the Changchun–Yanji suture zone and comprise mainly monzogranite and syenogranite, with minor quartz monzonite. New zircon U–Pb data measured by laser ablation inductively coupled plasma mass spectrometry (LA–ICP–MS) yield emplacement ages of 262–256 Ma, reflecting middle–late Permian magmatism. Geochemically, the rocks contain 60.53–73.33 wt. % SiO2, 12.60–18.35 wt. % Al2O3, 3.50–8.10 wt. % K2O, 0.18–0.91 wt. % TiO2, and 0.22–1.01 wt. % MgO, and exhibit weakly peraluminous (A/CNK = 0.86–1.01) and high-K calc–alkaline and shoshonitic characteristics, indicating I-type granite affinities. They are also characterized by low Sr and high Yb contents, reflecting low-pressure magma source conditions with residual plagioclase (i.e. amphibolite facies). These granitoids also exhibit geochemical characteristics typical of arc–type magmatic rocks, with enrichment in large ion lithophile elements (LILEs; e.g. Rb, Ba, and K) and light rare earth elements (LREEs), and depletion in high field strength elements (HFSEs; e.g. Nb, Ta, Ti, and P) and heavy rare earth elements (HREEs), indicating that they were formed in a subduction-related setting. Moreover, magmatic zircons from the studied rocks have relatively homogeneous Hf isotopic compositions (εHf(t) = – 1.4 to +15.1) and corresponding two–stage model (TDM2) ages of 1839–348 Ma, indicating that they were generated by partial melting of Paleoproterozoic–Phanerozoic accreted lower crust, with minor contributions of ancient crustal materials. Their geochemical characteristics and specific lithological assemblage, together with the temporal–spatial distribution of Permian granitic magmatism, indicate that the formation of middle–late Permian granitoids in the northern margin of the NCC was related to southward Paleo–Asian oceanic subduction. Data from this and previous studies lead us to favour a double-sided, early–late Permian subduction model, with the Paleo–Asian Ocean closing after the late Permian. Graphical Abstract
