EFFECT OF AGE, AND VITAMIN E AND SELENIUM ADMINISTRATION ON SEMEN CHARACTERISTICS OF NEW ZEALAND WHITE RABBIT BUCKS

The aim of this study was to investigate the effect of age and supplementation with vitamin E and selenium combination on semen characteristics of New Zealand White (NZW) rabbit bucks. Thirty six NZW rabbit bucks were divided into three equal experimental groups according to their age. Group 1: young age (4-5 months), Group 2: middle age (9-10 months) and Group 3: old age (20-24 months). Each group was divided into two subgroups (treatment and control). Treated group was subcutaneously injected with 50 mg vitamin E and 0.1 mg selenium per kg live body weight, while the other was given saline solution and served as control. Experimental animals were injected once a week for 12 weeks. After six weeks of treatments, semen was collected weekly for six successive weeks. Reaction time was recorded; semen characteristics and plasma testosterone were estimated. Results showed that the young age group had significantly (p<0.05) lower sperm cell concentration/ml, total motile sperm/ml and insignificantly lower initial motility and sperm viability than those recorded in other ages. The middle age group had significantly (p<0.05) higher whole ejaculate volume than other groups. Also, they had significantly (p<0.05) higher sperm membrane integrity and significantly (p<0.05) lower fructose level than those recorded in the old age group, but not significant with the young age group. Animals treated with Vit. E and selenium showed significantly (p<0.05) improvement in most semen quality traits compared with control animals. Averages of sperm viability, motility, sperm concentration, total motile sperm per ml, ejaculate volume, sexual libido and sperm membrane integrity were significantly higher in bucks received Vit. E and selenium than those recorded in control bucks. In addition, best results were observed in the middle age group, meanwhile, semen characteristics of young and old rabbit bucks did not decrease dramatically and still in acceptable range. It could be concluded from our study that young and middle age bucks with supplementing with Vit. E and selenium could be used successfully and efficiently in rabbit breeding systems.
Evaluation the impact of selenium-enrichment and some organic matter on morphophysiological and essential oil in Anethum graveolens L

Original Article Recently, the role of selenium (Se) as an antioxidant has generated wide interest in humans and animal-based on its presence in antioxidant defense systems. Unfortunately, people in many countries fail to get enough selenium. Dill (Anethum graveolens L.) is one of the medicinal plants belonging to the family Apiaceae. Any kind of herbal drug is influenced by many factors. Genetic, pre-harvest (season of harvest, soil, type of water), and post-harvest factors (storage, temperature, moisture) can affect total phenolic, flavonoid, and antioxidant capacity as well as other elements and compounds. The aim of this study was to investigate the effect of selenium trace in combination with and acids on the enrichment of dill. The experiment was conducted in a completely randomized design with three levels of acid (0, 50, and 150 mmol/L) and selenium application at 5 levels (0, 6, 8, 12 and 16 mg/L). The results of this experiment showed that the effect of selenium at different level of acids was significant. So that shoot fresh and dry weight, chlorophyll, essential oils, selenium content, and antioxidant enzymes were affected by increasing treatment level. The results indicated that (50 mg/L acid+12 mg/L sodium selenate) increased and improved some morphophysiological traits and essential oils including ɑ-Pinene, β-Myrecene, ɑ-Phellandene, and Carvone. © 2020, Science and Research Branch, Islamic Azad University.

Establishment of a spontaneously started sourdough in Vietnam

Received 30 Oct 2019 Revised 22 Apr 2020 Accepted 31 Mar 2021 The use of sourdoughs in bread baking in Vietnam has recently been increased but little is known about microorganisms in those sourdoughs. This study was to assess changes in pH value and microbial density of a sourdough from bread flour (BF) and a sourdough from all-purpose flour (AF) during propagation. The results showed that the type of flour did not cause a significant difference in pH changes, but it could contribute to the distinct levels of lactic acid bacteria (LAB) and yeast in the two sourdoughs. The BF sourdough gained proper maturation in 15 days when it reached pH of 3.69, 1.3 x 10 CFU g LAB and 7.4 x 10 CFU g yeast. Meanwhile, the AF sourdough had lower levels of LAB and yeast (3.9 x 10 CFU g and 1.0 x 10 CFU g, respectively). Sequencing analysis revealed the presence of Lactobacillus plantarum in the BF sourdough on the 10 and 15 days of the propagation process. Wickerhamomyces anomalus was found on the 10 day while Saccharomyces cerevisiae was detected on the 15 day. This sourdough can be used in further studies to assess the benefits of sourdough in bread baking. Keywords
Moderating role of organizational trust in the relationship between perceived job insecurity and proactive behaviour

This study examined the moderating role of organizational trust in the relationship between perceived job insecurity and proactive behaviour of bank employees. Six hundred and twenty-nine commercial bank employees (409 men and 220 women) in Akwa Ibom state, South-South, Nigeria participated in the study. They were selected from a population of 1,074 employees using purposive sampling technique, while the banks were selected using systematic sampling technique. Three instruments were used for data collection, namely, Job Insecurity Scale (JIS), Organizational Trust Inventory (OTI), and Proactive Personality Scale (PPS). Data generated were analyzed using Hayes’ regression-based PROCESS macro for SPSS in order to test the hypotheses. Result of the study revealed that job insecurity was positively related to proactive behaviour. Similarly, organizational trust was positively related to proactive behaviour. Contrary to expectation, organizational trust did not moderate the relationship between job insecurity and proactive behaviour. Based on the above relevant findings, strategies to encourage trust in the organization by workers were suggested.
Peculiarities of girth body sizes in men with mild and severe psoriasis course

Given the most frequent manifestation of psoriasis at a young working age and in some cases severe, continuously recurrent course, the presence of many treatments, none of which is a guarantee of complete recovery and no recurrence – now there is an urgent need to find prognostic signs therapy and prevention of relapses. In the absence of ideal biomarkers, the study of constitutional markers becomes crucial. The aim of the study was to examine the differences in girth body sizes between healthy and/or psoriatic men depending on the severity of the disease. Anthropometric examination according to V.V. Bunak was performed for 32 men of the first mature age patients with mild and 68 with severe psoriasis course. The PASI index was used to clinically assess the severity and area of psoriatic lesions. The control group, according to anthropometric parameters, consisted of 82 practically healthy men of the same age, selected from the database of the research center of National Pirogov Memorial Medical University, Vinnytsya. Statistical data processing was performed in the license package “Statistica 5.5” using non-parametric methods of evaluation of the obtained results. In patients with psoriasis of mild and severe course, compared with healthy, we found: greater values for – the girth of the shoulder in a tense state by 8.9% and 6.8%; shoulder girth in the unstressed state by 14.2% and 12.3%; forearm girth in the upper part by 8.0% and 7.1%; forearm girth in the lower part by 4.2% and 4.5%; hand girth by 5.1% and 5.8%; hip girth by 11.4% and 9.3%; hips circumference by 8.7% and 6.5%; crus girth in the upper part by 10.2% and 7.9%; crus girth in the lower part by 8.7% and 5.9%; neck girth by 6.9% and 7.8%; waist circumference by 17.1% and 18.2%; chest girth on inspiration by 7.8% and 7.2%; chest girth on exhalation by 10.6% and 10.3%; chest circumference at rest by 10.0% and 9.6%. Thus, there are pronounced differences in the girth sizes between healthy and patients with mild and severe psoriasis Ukrainian men of the first mature age. Between patients with varying degrees of severity of dermatosis, differences are established only for the girth of the crus in the lower part.
RISK FACTORS FOR IN- STENT RESTENOSIS IN PATIENTS WITH PERCUTANEOUS CORONARY INTERVENTIONS

Percutaneous coronary intervention (PCI) is one of the main treatments for patients with coronary heart disease (CHD), and in-stent restenosis (ISR) after PCI has gradually attracted clinical attention. Although the rates of in-stent restenosis (ISR) have been reduced dramatically with the introduction of drug-eluting stents (DESs), the ISR problem has not been completely resolved. The aim of our study was to identify the risk factors influencing the likelihood of restenosis after stent implantation. We retrospectively review 115 patients (mean age 63.4±0.3years) with previous PCI for acute coronary syndrome or stabile angina pectoris, hospitalized at the University clinic of cardiology in Skopje for follow-up coronary angiography. The data were obtain from coronary intervention database. Seventy two patients were diagnosed as ISR and forty three patients had no significant ISR. Restenosis rates were higher among patients with diabetes mellitus, hiperlipidemia and smoking history and the differences between two groups were statistically significant (all p<0.05). The restenosis rates were higher in patients with BMS compared to first and second generation DESs (p<0.01). The smaller (diameter <3mm) and longer stents (>20mm) were associated with more in-stent restenosis with significant statistical difference among group (p < 0.05). Predictors of in-stent restenosis were identified with linear regression analyses. The diabetes, hyperlipidemia, stent features were independent risk factors for ISR (all p < 0.05). In conclusion, for patients with PCI risk factors identification and management is warranted to prevent the ISR.
WORKING PAPER SERIES

I present a statistical discrimination model of the labor market in which persistent negative employer biases about the productivity of a group of workers arise through hiring and learning about the group. Bayesian profit-maximizing employers endogenously develop biased beliefs based on their hiring experiences which lead to asymmetric learning about the group’s productivity across employers. Optimal hiring follows a cutoff rule in posterior beliefs and market-clearing wages below which employers stop hiring from the group, preserving negative biases and leading to a negatively-skewed aggregate distribution of beliefs. Long-run discrimination in the form of a wage below the group’s expected productivity can arise even with market competition, without productivity differentials across worker groups or prior employer biases, and regardless of worker signaling or investment decisions. The model generates predictions analogous to the Becker taste-based model, in a statistical framework with beliefs replacing preferences, rationalizing apparent prejudice as the result of “incorrect” statistical discrimination. * I thank Martha Bailey, John Bound, Charlie Brown, David Miller, Tanya Rosenblat and Jeff Smith for continued guidance and feedback.

Testing for COVID-19: Some Statistical Issues

The swift spread of the novel coronavirus is largely attributed to its stealthy transmissions in which infected patients may be asymptomatic or exhibit only flu-like symptoms in the early stage. Undetected transmissions present a remarkable challenge for the containment of the virus and pose an appalling threat to the public. An urgent question is on testing of the coronavirus. In this paper, we evaluate the situation from the statistical viewpoint by discussing the accuracy of test procedures and stress the importance of rationally interpreting test results.
Tertiary students’ housing priorities: Finding home away from home

Globally, 5 million students annually leave both high school and their homes for the first time in pursuit of a higher education, while some others may be transiting to a new country in search of an international education. If tertiary students are unable to access suitable accommodation, this could have several implications. First is the significant role of housing on one’s health, wellbeing, and quality of life as this can be an additional cause for stress and worry. Second, there is ample evidence that attests to the fact that students with access to settled housing have better educational outcomes than those with less settled housing. This paper examines tertiary students’ housing needs and preferences, towards providing them with suitable and stable accommodation during their study duration. A 26-item online questionnaire was administered to students enrolled at two regional universities in Australia. Participants were asked to choose their needs and preferences from eleven housing attributes, and rate them from ‘most important’ to ‘least important’ need. The results were analysed using SPSS. The results of the survey from both universities indicate that students’ most important need was for affordable accommodation (i.e. the lowest cost for rent) and accommodation offering recreational facilities rated the least important. This study fills a gap in understanding student priorities in housing in regional universities and offers insight to individuals and institutions involved in or intending to develop student accommodation on how to properly target and satisfy this sector. The research findings has wider application to regional or urban-based universities in Australia and globally.
Framing Multi-Stakeholder Value Propositions: A wicked problem lens

We use two dimensions of wicked problems involving complexity and complicatedness, and conduct a secondary analysis of seven technology venture case studies from Australia and New Zealand. We then categorise the configuration types of these firms' stakeholder value propositions in the context of their scale-up process. We contribute to the value proposition and business model development research streams by suggesting that the challenge of mediating value propositions that conflict can manifest itself in four types of configurations: easy, complicated, complex and wicked. Complicated and complex propositions are thorny, but with structures and processes in place, they can be adequately addressed. On the other hand, wicked propositions consist of many unknowns and require firms to collaborate with stakeholders to derive outcomes that align company scaling objective with stakeholder value propositions. The value of a thing is estimated from the advantages supposed to be derived from it, and depends very much upon time, place, and circumstances”
Unrealistic optimism and HEXACO traits as predictors of risk perception and compliance with COVID-19 preventive measures during the first wave of pandemic

The aims of this study were to examine possible differences and factors that contribute to risk perception and compliance with preventive measures at the beginning (T1) and the end (T2) of the first wave of COVID-19 pandemic. The sample consisted of 423 participants (M = 30.29, SD = 14.45; 69% female). Compliance, risk perception and trust in information were significantly higher in T1 than T2. For risk perception, significant predictors in both T1 and T2 were age, Emotionality (HEXACO-PI-R) and Unrealistic Optimism (NLE, Negative Life Events). Trust in information was a significant predictor in T1, while Unrealistic Optimism (Positive Life Events) was a signifi-cant predictor in T2. For compliance, significant predictors in T1 were gender and trust in information while in T2 were Emo-tionality, Extraversion, Conscientiousness (HEXACO-PI-R), NLE and trust in information, for both T1 and T2. In general, findings suggest a much more pronounced role of personality traits in adherence to protective measures at the end than at the beginning of the first wave of the COVID-19 pandemic in Serbia. Also, the results indicate the role of unrealistic opti-mism regarding negative life events in lower compliance with protective measures.
Compositional dependence of H2O solubility along the joins NaAlSi3O8-KAlSi3O8, NaAlSi3O8-LiAlSi3O8, and KAlSi3O8-LiAlSi3O8

Abstract The composition-dependence of the solubility of H2O in silicate melts along the binary joins NaAlSi3O8-KAlSi3O8, NaAlSi3O8-LiAlSi3O8, and KAlSi3O8-LiAlSi3O8 has been determined at 2 kbar and 1040 °C. The study involved 1 atm dry oxide fusion, hydrothermal saturation, isobaric rapid quench and macroscopic analysis for H2O using Karl Fischer titration (KFT) and microscopic investigation of homogeneity using infrared absorption spectroscopy, respectively. The solubility of H2O in these melts increases in the order KAlSi3O8 (5.12 wt%) < NaAlSi3O8 (6.03 wt%) < LiAlSi3O8 (7.32 wt%). The total relative weight percent variation in solubility is 43%, which corresponds to a relative mole percent variation of 23%. Along the joins, small but systematic deviations from additivity are observed at the 1σ uncertainty level. These deviations are positive on the NaAlSi3O8- KAlSi3O8 join but negative on the LiAlSi3O8 -bearing joins. The present results confirm the early suggestion of Voigt et al. (1981) that solubility variation along the NaAlSi3O8-KAlSi3O8 join is nonlinear and disagree in detail with the equimolal approximation of Burnham (1975, 1981) and Burnham and Davis (1974). Models of H2O solubility must take into account not only the nonequimolal solubility of H2O in feldspathic melts but also nonlinear binary variations as well. We interpret the relative solubilities of the end-member compositions in terms of the relative stability of the tectosilicate melt structure and the nonlinearities along the joins in terms of the next-nearest neighbor distributions of Al and Si in these melts.
ANTHROPOMETRIC PARAMETERS AND INDEXES IN 9 YEAR-OLD-CHILDREN FROM R. NORTH MACEDONIA

The aim of the study was the detection of sex-specific differences of anthropometric parameters and indexes that were used as indicators of growth and nutritional status in the 9-year-oldchildren from R.North Macedonia. The study included 280 healthy children aged 9 (140 boys, 140 girls) from R.North Macedonia. Fourteen anthropometric parameters were measured which define longitudinal, circular and transversal measures of skeleton using standard equipment and measurement technique. The following indicators were calculated: weight-for-age (BW), height-for-age (BH), BMI, mid-upper circumferencefor-age (MUAC) and skinfolds thickness (scapula SFSc and triceps SFTr)-for-age. The results have shown significant sex-specific differences in favour of boys for the height, four transversal and three circular parameters, with exception of mid-upper-arm circumference and skinfolds that were apparently higer in girls. Values of the 50 th percentile in boys were as follows: 33 kg for BW, 136 cm for BH and 17.65 kg/m for BMI, 19.8 cm for MUAC and for skinfolds: SFSc 8 mm and 12 mm for SFTr.The values of these parameters in girls were: 32 kg for BW, 135cm for BH and 17.47 kg/m 2 for BMI. 20.8 cm for MUAC and for SFSc 9.8 mm and 12.8 mm for SFTr. These results can be used as criteria for the assessment of the morphological characteristics and detection of deviations in the growth and nutritional status in children aged 9.
The Norwegian EV success continues

The incentive package will be revised and adjusted parallel with the market development in coming years. The tax incentives will stay in place to 2018 and then be revised. From 2017 the local governments will decide the incentives such as access to buss lanes and free municipal parking. Free toll roads will be replaced with a new system with differentiated prices depending on CO2 and NOx emissions.
Point of View Research Accounting and Auditing

The impact of company size, profitability, and foreign ownership on the disclosure of corporate social responsibility in mining companies on the stock exchange is explored in this study. The data in this analysis was derived from the IDX-listed financial statements of mining companies. Via a database library, this research uses secondary data by collecting data relevant to the research approach used for data analysis is multiple linear regression analysis. The findings showed that the greater the size of the organization, the improved Corporate Social Responsibility (CSR) disclosure, the positive and important effect of the company's size on Corporate Social Responsibility. The findings showed that profitability had a beneficial and significant effect on corporate social responsibility (CSR). The greater the performance of the business, the greater the disclosure of Corporate Social Responsibility (CSR). The results of the hypothesis test suggest that the greater the ownership of foreign shares held by a corporation, the greater the disclosure of corporate social responsibility. The size of the company and foreign ownership at the same time (together) have a positive and relevant influence on corporate social responsibility.
