Teaching Writing in Nigerian Secondary Schools: Teachers’ Attitude toward the Teaching of Writing and Their Writing Self-efficacy

: This study sought to determine English Language teachers’ writing self-efficacy and attitude towards the teaching of essay writing in secondary schools in Nigeria. Two research questions and four hypotheses guided the study. The descriptive survey research design was adopted. Sixty (60) English Language teachers (21 males and 38 females) in senior secondary schools in Benin City, Nigeria formed the sample for the study. The “Questionnaire on Teachers’ Attitude toward the Teaching of Writing and Writing Self-Efficacy (QTASE)” was used in the collection of data. Descriptive statistics, independent samples t-test and ANOVA were used for data analysis. Findings revealed that teachers have negative attitude towards the teaching of essay writing and have low writing self-efficacy. In addition, there were significant differences in teachers’ attitude toward the teaching of essay writing and their writing self-efficacy based on gender and qualification. However, teachers’ writing self-efficacy did not differ based on qualification. Recommendations were made in line with the findings of the study.
Should They Stay or Should They Go? CEO Appointments and Performance in a Transitional Economy

This study examines the corporate operating performance surrounding CEO appointments from 2001-2013 to firms listed on the Warsaw Stock Exchange. We find that the decision to reappoint or to replace a CEO is preceded by a decline in corporate operating performance. We fail to find, however, improvements or stability in operating performance following either the replacement or reappointment of the incumbent CEO. The likelihood of CEO replacement is greater if the firm does not perform well in the period preceding the appointment. We conclude that there are inefficiencies or inadequacies in the corporate governance system of Polish publicly traded firms.
TFAP2A Induced ITPKA Serves as an Oncogene and Interacts with DBN1 in Lung Adenocarcinoma

The inositol polyphosphate kinase (IPK) family member ITPKA (inositol 1,4,5-trisphosphate 3-kinase) regulates the levels of many inositol polyphosphates which are important in cellular signaling. Several recent studies reported the aberrant expression of ITPKA in malignancy disease and usually made cancer more aggressive. However, the contribution of the inositol polyphosphate kinase ITPKA to lung cancer development remains unclear. Here we report that ITPKA is overexpressed in lung adenocarcinoma (LUAD) and positively correlated with advanced clinical parameters. ITPKA contributes to the malignant phenotypes in-vitro. Mechanistically, ITPKA executed its action through the inducting of epithelial-mesenchymal transition (EMT) and interacting with Drebrin 1 (which is related to cancer metastasis). Moreover, the hyper-expression of ITPKA in LUAD is transcriptionally activated by the transcription factor TFAP2A. In survival analysis by using tissue microarray (TMA), we indicate that ITPKA is hyper-expressed in LUAD tissues compared to adjacent normal tissues, and increased expression of ITPKA is associated with poor prognosis. Collectively, this study indicates that TFAP2A induced ITPKA hyperexpression promotes LUAD via interacting with Drebrin 1 and activating epithelial-mesenchymal transition (EMT). ITPKA might represent a potent candidate for the treatment and prognostic prediction of LUAD.
“Exchange Rate Risk” within the European Monetary Union? Analyzing the Exchange Rate Exposure of German Firm

In this paper we show that inflation differentials among the countries in the European Monetary Union (EMU) are an economically significant risk to German firms, which make up the largest economy in the EMU. This risk can be interpreted as real “exchange rate exposure” resulting from trade within the euro area. Actually, we find that this EMU exposure is nearly as high as the standard exchange rate exposure caused by trade with non-EMU countries. Moreover, our analysis shows that many of the conventional factors that drive firm-specific exchange rate risk, such as size, debt ratio, asset turnover and foreign business activity, also determine EMU exposure in an economically meaningful way. However, EMU exposure challenges firms’ risk management, particularly as it cannot be reduced by standard financial hedging instruments, such as currency derivatives.
School Students' Performance Predication Using Data Mining Classification

Educational management information systems generate huge amounts of data which hide a very useful knowledge. The techniques and methods used to discover the knowledge from students data are known as Educational Data Mining (EDM). The main objective of EDM is to improve students and teachers performance. Many researchers analysed students' behaviour to obtain useful knowledge that can help educators in planning for improving students' performance. There are two approaches which can be used to discover knowledge; by statistical methods and by DM techniques such as classification. This paper proposes a students' performance prediction model based on DM classification algorithms (Naïve Bayes, Decision Tree and K-NN). The dataset was collected from a preparatory male schoolin Gaza strip, includes over 1100 records. Obtained results show that Decision Tree gives the best results. Moreover, the results indicates that social case has little impact on the students' performance, while the academic features such as previous year and first term results have more impacts on the performance. These results can be used in improving students' performance by predication their retention early to minimize students' failure.
Effect of 17 α -methyl testosterone on sex reversal and growth of Nile tilapia (Oreochromis niloticus L., 1758)

The present study aims at developing a production of monosex population of all male Nile tilapia (Oreochromis niloticus) using 17α-methyltestosterone (17α-MT). Three treatments with a control (Control, T-1, T-2, and T-3) in triplicates were set up using completely randomized design (CRD). The control group diet was devoid of 17α–MT. The remaining groups T-1, T-2, T-3 and T-4 were fed with feed containing 50, 60 and 100 mg kg-1 of 17α –MT. Three days old fry were stocked at the rate of 300 nos per tank. The fry were fed with experimental diet for 21 days. After that it was shifted to FRP tanks. The maximum mean length and body weight was observed in T-2 is 80 ± 3.87 mm and 59.5 ± 7.4 mm respectively. Gonadal histology from 3 months reared O. niloticus for sex reversal was observed that 56.7 %, 83.3 %, 93.3 % and 90 % males respectively. The highest male population of 93.3% males was produced from treated groups of (T-2) 60 mg kg-1 17 α-MT.
Maser The Medication Adherence, Factor Influencing Adherence and The Executives Of Intense Asthma Children’s In Tamilnadu

The commonness and related Weight of ailment because of asthma, it required to get an ideal control of the malady and improve the results of these patients. In any case, it has been seen that there is poor adherence to the treatment, which prompts the problematic control of the illness. To read the adherence for treatment in these patients to survey the effect of Wellbeing instruction and self-activity plan to improve adherence. A forthcoming report Was done in a sum of 986 asthma patients over a time of 3 years. When incorporated into the examination, the patients are followed up after 12 Weeks of non-adherence to the treatment. It was seen that solitary 108 patients (10.95%) had normal non-adherence, and 878 patients (89.05%) Were adherence to the treatment. Elements that Were related to poor adherence Were: LoWer instructive level, poor financial status, changes in routine, and patient's evil mentalities toward Wellbeing. Subsequent to utilizing the different systems for improving the adherence in these patients, the adherence expanded in patients (61.32%) among the prior defaulted patients, while the staying 188 patients (38.68%) Were seen as non-adherence even after different instructive procedures. Nonadherence in asthma the executives is an unavoidable truth and adherence improving system likely as a viable decent doctor and patient relationship. Individualized composed activity plans dependent on pinnacle expiratory stream are proportionate to activity plans dependent on indications.
Abortion outbreak caused by Campylobacter fetus subspecies venerealis and Neospora caninum in a bovine dairy herd

In November 2015, an abortion outbreak occurred in a commercial dairy herd of 650 Holstein cows in Florida department, Uruguay. Forty-five cows aborted within three weeks. Five fetuses were subjected to gross and microscopic pathologic examination, and microbiological testing. One fetus had fibrinous epicarditis and peritonitis, and neutrophilic bronchopneumonia. Campylobacter fetus subsp. venerealis was detected by direct immunofluorescence, isolated and identified by PCR and sequencing of the 16S rDNA in the abomasal fluid and/or lung. Histologic examination of two other fetuses revealed non-suppurative necrotizing encephalitis, lymphohistiocytic myositis and myocarditis, and lymphocytic interstitial nephritis. In these fetuses, N. caninum antigen was detected intralesionally by immunohistochemistry, and N. caninum DNA was amplified by PCR on formalin-fixed paraffin-embedded brain. Antibodies against N. caninum were detected by indirect immunofluorescence in 10 of 27 cows, with titers ranging from 1/200 to 1/3200. The results indicate that two abortigenic microorganisms may coexist and cause contemporaneous abortion in a herd. We highlight the importance of performing multiple diagnostic tests in various aborted dams and fetuses from the same herd for the etiologic confirmation of bovine abortion syndrome.
A comparative analysis of Airbnb in London and Barcelona: The ethnographic research process and its discontents

Peer to peer (P2P) accommodation platforms like Airbnb or HomeAway have transformed not only the hospitality industry but they have also created wider economic change in other adjacent industries and in society in general. Because of this, many stakeholders are now trying to proactively shape the evolution of these platforms, as reflected by numerous actions by policymakers, industry representatives, media outlets and the public across the world. This paper reports on the authors’ experience conducting a comparative study over a period of one year and a half researching issues surrounding the sharing economy, by using Airbnb as a case study. The city-based case study (London and Barcelona) examines the experiences and views of relevant stakeholders in the Airbnb sphere: hosts, guests, Airbnb public policy managers, rental apartment companies, council representatives and other local authorities. The barriers and opportunities for ethical practice were also identified and reported according to the views of these stakeholders. Our main contribution is the identification of the challenges derived from conducting research of complex nature, as in the case of comparative studies in two international settings, focusing on a controversial phenomenon, in this case, the sharing economy platform Airbnb. We also reflect on some of the strategies that we used to overcome some of these challenges with the aim of supporting other researchers working in a similar context. By using participant observation, in-depth interviews and focus groups, this study gathers different perspectives on the complex topic of the operation of Airbnb in two European cities, London and Barcelona, that are also major tourist destinations.
Host Availability, Repulsive Companion Planting, and Predation Interact and Shape How a Parthenogenetic Aphid Population Responds to a Stratified Ecological Challenge

Phloem-feeding insects strive to offset the disadvantageous effects of stressors to sustain their offspring and survive. Adaptive responses to environmental stress are not well understood under complex influences of companion planting, natural enemies, and host gradient. In this study, under predation by lacewing Chrysoperla carnea Stephens (Neuroptera: Chrysopidae), we survey the responses of green peach aphid Myzus persicae Sulzer (Hemiptera: Aphididae), reared on different densities of cabbage Brassica oleracea L. (Brassicales: Brassicaceae) to its shallot companion Allium cepa (L.) var. aggregatum G. Don (Asparagales: Amaryllidaceae). Firstly, aphid aggregative abundance was strongly influenced by shallot perturbation, predator presence and changes in cabbage-host biomass, altering aphid phenotypic plasticity. Interestingly, the shallot and predation negative impacts can be of similar magnitudes. Secondly, changes in the cabbage-host availability and biomass, especially under predation, had a strong impact on aphid traits. Our study underscores the benefits of including shallots as crop-companions in augmenting pest control, but also suggests that the outcome of coupling companion planting with natural enemies is context-dependent and thus should be empirically applied. At the confluence of ecology and agronomy, this work provides insights on how manipulated functional biodiversity may function as an alternative strategy for pestilent herbivory management in model and green-house systems.
Diversity of mitochondrial DNA in fallow deer (Dama dama) from Brijuni National park, Croatia - short communication

Fallow deer (Dama dama) are one of the most important game species in Europe and approximately 5 million animals are raised on farms globally. These deer are considered to be indigenous in Europe, but during the last ice age became extinct from most of their range except Sicily, the Balkan Peninsula and Anatolia. Research suggests that after the Middle Ages the indigenous population only survived in Anatolia (today’s Turkey and Iran), so all present worldwide fallow deer populations were reintroduced from there. In Croatia, the species is mostly kept in fenced areas, while breeding in open hunting grounds or farms is rare. The goal of our research was to analyze the genetic diversity of fallow deer that live in the open grasslands of the Croatian island Veliki Brijun on an area of 5.72 km2. DNA was isolated from the muscle tissue of 22 animals and 405 base pairs of mitochondrial DNA control region were sequenced. One polymorphic site and two haplotypes were detected, both matching sequences from Germany, while one of the haplotypes was also previously detected in fallow deer in Hungary and Italy. The mtDNA diversity of Dama dama from Brijuni National park was rather low but, considering the island’s isolation, the obtained results were in accordance with the diversity of previously researched European continental populations of fallow deer.
Thermal characterization of the In–Sn–Zn eutectic alloy

Thermal properties, including melting temperature, latent heat of melting, specific heat capacity and thermal conductivity, of a low-melting In–Sn–Zn eutectic alloy were investigated in this work. The In–Sn–Zn eutectic alloy with nominal composition 52.7In-44.9Sn-2.4Zn (at.%) was prepared by the melting of pure metals under an argon atmosphere. The conducted assessment consisted of both theoretical and experimental approaches. Differential scanning calorimetry (DSC) was used for the measurement of melting temperature and latent heat, and the obtained results were compared with the results of thermodynamic calculations. The measured melting temperature and the latent heat of melting for the In–Sn–Zn eutectic alloy are 106.5±0.1 °C and 28.3±0.1 Jg-1, respectively. Thermal diffusivity and thermal conductivity of the In–Sn–Zn eutectic alloy were studied by the xenon-flash method. The determined thermal conductivity of the investigated eutectic alloy at 25 °C is 42.2±3.4 Wm-1K-1. Apart from providing insight into the possibility for application of the investigated alloy as the metallic phase-change material, the obtained values of thermal properties can also be utilized as input parameters for various simulation processes such as casting and soldering.
The Usefulness of Different Forms of Translation in a CLIL Environment

This article aims to explore the role translation can play within a CLIL environment. The hypothesis that the research project, on which this paper is based, wanted to prove, was that the introduction of materials and activities informed by the use of various forms of translation could lead to an enhancement of the performance in students attending CLIL courses at the level of both content and language. As Snell-Hornby stated at the end of the twentieth century, the practice of translation in our society has increasingly acquired a fundamental importance. Yet, for many years, translation has often been excluded from the language class. However, in our multicultural society, translation has become an essential tool in various professional and social contexts, including the multicultural classrooms teachers act in. This article is based on my experience as a teacher trainer (English language and CLIL methodology) and on the results obtained during research which focused, in particular, on the use of various forms of translation in CLIL courses and which extended over the school years 2017-2018 and 2018-2019. As a result, this article argues in favor of translation in the CLIL class. On the basis of the outcomes obtained, it is my contention here that Learning Units such as those presented here, where translation works in synergy with CLIL methodology, are perceived as motiving by students, thereby facilitating the development of various disciplinary and communicative skills.
Tell Me What You Want: Disentangling the Impact of Service Specification Option Repertoires on Service Performance in Gig Economy

Confronted with an increasingly competitive landscape for credence services in the gig economy, workers on gig economy platforms are compelled to compete by configuring the service specification options on such platforms to enhance the visibility of their gig offerings. Motivated by a dearth of research on the effects of discrete configurations of service specification options on service quality and sales, this study builds on competitive repertoire theory to advance a research model that seeks to unveil how the volume, complexity, and heterogeneity of service specification option repertoires affect service quality and sales. We empirically validate our hypotheses with a dataset comprising 3,307 lifestyle-themed credence services from Fiverr, one of the largest e-marketplaces for gig economy in the world. We discover that repertoire volume is positively associated with both service quality and sales whereas repertoire complexity is only positively associated with service quality. Repertoire heterogeneity, on the other hand, is neither associated with service quality nor with sales.
Testing performances of a newly designed olfactometer

Dynamic dilution olfactometry as regulated by EN 13725 requires instrumentation of adequate technology and in order to spread the use of Dynamic Olfactometry high usability of the device is a must. A new dynamic dilution olfactometer has been designed and manufactured after the experience gained in previous prototype development and performance studies as well as from experimental applications. Materials have been selected in order to be compliant with the expected next-to-come updates of the EN13725 technical norm and checks on pneumatic steps required by the odour concentration analysis procedure have been implemented. In order to generate specific dilutions in a wide range, a high precision stepper motor is used, instead of the more common calibrated orifices. The instrument comes with option of incrementing dilution with a factor of √2 (instead of more usual 2), so to increase resolution of the odour measurements. The consumption of neutral compressed air has been highly reduced in comparison with previous prototypes. The new features of the instrument as well as the available dilution steps will be presented. A careful check of accuracy and operative speed at high dilutions has been performed. Standard n-butanol, and samples from ambient air collected in close proximity from odour emitting sources have been collected for testing the olfactometer and the panel response. A market top instrument has been considered for sake of comparison.
Muslim Refugees in Serbia – Narrating Gender Role Identity Change

Forced migration is a highly stressful event that can cause changes in identity work. The aim of this research was to determine in what way the migration and prolonged stay in Serbia, a country that differs from both the refugees’ heritage cultures and wished host cultures on many cultural dimensions, influenced the young Mu slim refugees’ gender role identities. Semi-structured interviews with seven female and eight male refugees coming from Afghanistan, Iran and Pakistan, staying for several months in Serbia were conducted. Narrative inquiry, focused on recurring themes and changes in the past– and present-time narratives about gender role identities, yielded three types of narratives. The most frequent narrative, Expressing what was suppressed, points to identical past– and present-time narratives, but significant changes in the way gender role identities are expressed and pursued, self-confidence and interpersonal relationships. In narrative Reinventing oneself a major shift in gender role identity was noticed. Narrative Remaining the same, reflects changes in neither gender role identities nor their expression. Most participants applied integration strategies during the migration and moved towards individualism, femininity and rational values, whereas a few, exclusively male refugees, retained traditional patriarchal values.
Characterizing the Potential of Being Emerging Generic Technologies: A Bi-Layer Network Analytics-based Prediction Method

Despite tremendous involvement of bibliometrics in profiling technological landscapes and identifying emerging topics, how to predict potential technological change is still unclear. This paper proposes a bi-layer network analytics-based prediction method to characterize the potential of being emerging generic technologies. Initially, based on the innovation literature, three technological characteristics are defined, and quantified by topological indicators in network analytics; a link prediction approach is applied for reconstructing the network with weighted missing links, and such reconstruction will also result in the change of related technological characteristics; the comparison between the two ranking lists of terms can help identify potential emerging generic technologies. A case study on predicting emerging generic technologies in information science demonstrates the feasibility and reliability of the proposed method.
Antidiabetic potential of Triphala Guggul - an ayurvedic formulation in alloxan-induced diabetes animal model

The purpose of this study was to evaluate the potential antidiabetic drug Triphala guggul (TG), an indigenous polyherbal Ayurvedic formulation in an alloxan-induced diabetes rat model. Diabetes mellitus was induced in rats. The rats were divided into nine groups, including the groups of normal control which received the vehicle, the standard group (Glibenclamide) and rats with induced diabetes were treated with the tablet of Triphala guggul and Triphala guggul churna in doses of 100, 200, 400 mg/kg body weight, respectively. They were administered orally for 28 days on a single dose. Blood was collected from the vein in the tail on days 7, 14, 21 and 28. Biochemical estimates were made using blood serum. Acute toxicity studies did not reveal toxicity in rats. For 28 days, Administration of Triphala guggul tablet and Triphala guggul churna formulations improved oral glucose tolerance in diabetes-induced rats and after 28 days, resulted in a significant reduction in serum glucose level compared to normal control rats. These formulations do not affect the kidney, adipose tissue, and liver. The Triphala guggul formulation has a promising antidiabetic property and is effective in the treatment of diabetes.
