Influence of Plant Leaf Texture on the Development, Reproduction and Life Table Parameters of the Predacious Mite Cydnoseius zaheri (Acari: Phytoseiidae)

Influence of plant leaf texture of camphor, guava and fig on development, reproduction and life table parameters of the phytoseiid mite, Cydnoseius zaheri (Yousef and El Borolossy) was studied at 27 °C and 70% R.H. as rearing substrates. Cydnoseius zaheri successfully developed and reproduced on different plant leaves. Guava and camphor leaves were the most appropriate surfaces as individuals induced the shortest generation period and the highest reproduction rate. In contrast, fig leaf was the least suitable surface. A total of 53.0, 41.6 and 36.9 eggs/&8482; were obtained when guava, camphor and fig leaves were provided as rearing substrates. The intrinsic rate of increase (rm) and the finite rate of increase (exp rm) were 0.280 and 1.323 on camphor, 0.261 and 1.298 on guava and 0.169 and 1.183 on fig, respectively. Cydnoseius zaheri showed the highest fecundity rate (Mx), which compensated its lowest survival rate (Lx), on guava leaf. However, the predator exhibited the highest survival rate and the lo.
An exploratory study of undergraduate law students’ experience of online peer and self-grading: Towards an experiential perspective

Many studies have reported on the use of online technology in teaching and learning to engage students and to overcome limitations in time and place. However recent research has found integration of technology to be less successful in fostering quality student learning. This study suggests to further our understanding of student participation in learning activities involving online learning by use of the participatory qualities framework. The qualities reference the degree to which expressivity, exposure, investment, sociality and persistence is present in a learning activity. Research on this subject is still in its exploratory stage, thus the exploratory research question: How do students experience the structuring context for participation in the learning activities they engage in online. Data was collected through focus group interviews with a purposive sample of students (N=8) in an undergraduate Law programme at Aarhus University, Denmark. During a first semester course, students were invited to participate in a learning activity, which involved online peer and self-grading. Six elective assignments were offered to 74 students throughout the semester. Following almost full participation in the first assignment, the number of students participating decreased throughout the rest of the course. Preliminary data analysis suggests that students experienced the activity to involve high commitment (investment), while exposure, expressivity, and sociality were perceived to be low. It remains to be explored how student perception of participatory qualities influences student learning.
Assessment of Female Sexual Dysfunction in Patients with Premenopausal Female Pattern Hair Loss

Introduction: Female sexual dysfunction (FSD) is a serious problem that affects negatively the quality of life, interpersonal relationships and female self- confidence and might be a direct cause of psychopathological disturbances. Female pattern hair loss (FPHL) is a common cosmetically disturbing condition affecting many women with social and psychological consequences. Aim of the Work: Assessment of the relationship between female sexual dysfunction and Female pattern hair loss in premenopausal females. Methods: A case-control study was carried on 47 female patients with FPHL and 43 age- matched control women without FPHL among premenopausal women attending dermatology and Andrology outpatient’s clinics, Suez Canal University hospital during the period from May 2018 to January 2019. History taking, clinical examination and hormonal investigation (Free Testosterone, Total Testosterone, and SHBG) were performed to all participants in the study. Main Outcome Measures: The Female Sexual Function Index (FSFI) was used to assess the key aspects of female sexual function in patients and controls. FPHL was diagnosed and graded by Ludwig’s classification. Results: Mean age of patients group was 30.12 ± 5.49 years, Regarding FPHL grading, 55.3%, 42.6% & 2.1% of patients were grades 1, 2 and 3 Ludwig’s classification respectively. FSD was found in 44.7% of patients while it was 44.2% in control group (P > 0.05). FSFI score in patients group was 26.40 ± 4.61 and in control group was 27.05 ± 3.12 (P > 0.05). Correlation between FSD prevalence and grade of FPHL by Ludwig’s classification was statistically insignificant. FSD was significantly compromised by increasing age and parity in patients and control groups (P Conclusions: The present study suggests that FSD was not significantly related to FPHL. Increased age and parity may have strong impact on sexual function in premenopausal women, while androgen hormones levels were not determinant factor.
The Effect of President Trump’s Company-Specific Tweets on Company’s Stocks

Implementing event-study analysis, I find that President Trump’s tweets about publicly traded companies cause daily abnormal returns of 0.25% in a company’s stock in the same direction as the sentiment of the tweet: positive tweets increase abnormal returns by 0.25% on the day’s end, while negative tweets will cause -0.25% abnormal returns. Additionally, I find that President Trump’s company-specific tweets increase the daily abnormal trading volume and volatility of a company’s stock by 19%, regardless of tweet sentiment. For abnormal returns and abnormal trading volume, the effects of President Trump’s tweets do not last multiple days after a tweet. However, company stocks experience persistent higher volatility up to four days after President Trump tweets about them. When breaking the sample into subsets, I find that President Trump’s positive sentiment company-specific tweets have an asymmetrically stronger impact on a company’s abnormal returns and abnormal trading volume than that of negative sentiment company-specific tweets. For most measures, President Trump’s Twitter influence increases greatly when he tweets about a company during U.S. market trading hours. Outlier robust regressions confirm that the main abnormal returns results are not driven by outliers, while the results for volume and volatility appear to be inflated by outliers. Because this type of stock market influence causes persistent increased volatility and has potential to be abused, I recommend that lawmakers consider limiting the scope of presidents’ ability to tweet about publicly traded companies.
Analyzing Temporal Dynamics in Music

THIS ARTICLE INTRODUCES THEORETICAL and analytical tools for research involving musical emotion or musical change. We describe techniques for visualizing and analyzing data drawn from timevarying processes, such as continuous tension judgments, movement tracking, and performance tempo curves. Functional Data Analysis tools are demonstrated with real-time judgments of musical tension (a proxy for musical affect) to reveal patterns of tension and resolution in a listener’s experience. The derivatives of tension judgment curves are shown to change with cycles of expectation and release in music, indexing the dynamics of musical tension. We explore notions of potential energy and kinetic energy in music and propose that affective energy is stored or released in the listener as musical tension increases and decreases. Differential calculus (and related concepts) are introduced as tools for the analysis of temporal dynamics in musical performances, and phase-plane plots are described as a means to quantify and to visualize musical change.
The Effect of Inflorescence Bud Removal on Tuber Production in Helianthus Tuberosus L. (Asteraceae)

I investigated allocation to sexual and asexual reproduction in the Jerusalem artichoke, Helianthus tuberosus L. (Asteraceae), a clonal pseudoannual that is an herbaceous ramet for one season, but propagates as a perennial through tubers that quickly dissociate from the parent plant. H. tuberosus ramets grown from tubers allocated 24% of their end-of-season biomass to tubers and 9% to sexual organs, with substantial variation attributable to four genetic lines cultured from eastern Iowa. Experimentally induced failure of sexual reproduction increased allocation to asexual reproduction under common garden conditions. Plants with inflorescence buds removed produced more (82 vs. 69) and larger (4.4 g vs. 3.8 g) tubers than those with unlimited sexual reproduction. Total biomass allocation to reproduction in plants receiving the bud-removal treatment was equivalent to combined allocation to sexual and asexual reproduction in plants that produced flower heads and achenes. This suggests a complete diversion of resources from sexual to asexual reproduction when sexual reproduction is thwarted. Aboveground plant size did not change with treatment. These results suggest a flexible life history that can respond to sexual failure resulting from low pollinator availability or damage to inflorescences from herbivory or weather, with enhanced facultative production of asexual tubers capable of sexual reproduction the following year. Hereditary variation in allocation leaves open the possibility of local ad- aptation.
Cues from Introduced Fish Alter Shelter Use and Feeding Behaviour in Adult Alpine Newts

Amphibians are particularly affected by alien fish introductions and are declining worldwide. However, the behavioural mechanisms behind the observed cases of coexistence and exclusion patterns between adult amphibians and fish are poorly understood. In the present study, we aimed at testing the hypothesis that adult newts display different feeding and space use behaviour in the presence of fish cues (i.e. access less food resources and use more shelters than when fish cues are absent). To achieve this we measured behavioural patterns in 100 adult Alpine newts (Mesotriton alpestris) in a replicated laboratory design (20 tanks × 7 replicates across time). Half of trials involved individuals in indirect (visual and olfactory) contact with goldfish (Carassius auratus), a non-predatory species for adult newts. In the presence of fish, significantly more newts hid under shelters than in their absence, but this difference decreased over time. A lower number of newts fed in comparison with controls. These results show that newts responded to fish presence even in the absence of direct contact, but the differences were small. Newts decreased vital activities such as exploration of open areas and feeding. They also adjusted shelter use over time, suggesting a process of habituation or a risk assessment in the absence of direct risk. These results reveal that exploring behavioural patterns can aid in understanding the causes of exclusion and coexistence patterns between fish and amphibians.
Vitamin D Metabolism and Rickets in Domestic Animals: A Review

Rickets and osteomalacia are increasing in prevalence in people because of cultural practices, breast-feeding, decreased sun exposure, and increased sunscreen usage. Several hereditary forms of rickets owing to either renal phosphate wasting or defects in vitamin D metabolism are also reported in people. Rickets is well recognized in domestic animals, but published reports are not always supported by microscopic findings, and diagnoses based on clinical signs and radiology are unreliable. Most cases in domestic animals are caused by dietary deficiency of either vitamin D or phosphorus, but occasional inherited forms are reported in pigs, sheep, cats, and dogs. There is variation between species in susceptibility to dietary vitamin D and phosphorus deficiency and in the ability to manufacture vitamin D in their skin. A number of mouse models have been discovered or created to study human skeletal diseases and skeletal homeostasis. With the discovery that vitamin D is involved in not only calcium and phosphorus homeostasis but also in the immune system and cancer, there is great potential for new and existing animal models to generate valuable information about vitamin D and its many functions. This review presents an overview of vitamin D metabolism and rickets in domestic and laboratory animals and makes comparisons where appropriate with the disease in humans.
Assessment of the Willingness to Buy and the Use of Insecticide Treated Nets (ITN) among Caregivers of Under-Five Children Attending Immunization Clinics in a Private Tertiary Hospital in Plateau State, Nigeria

Introduction: Malaria control becomes effective if countries adopt the World Health Organization & Global Malaria Programme (WHO/GMP) recommendation with includes diagnosis of malaria cases and treatment with effective medicines, distribution of insecticide-treated nets (ITNs) and indoor residual spraying (IRS). Ownership and utilization of mosquito nets for malaria prevention is still sub-optimal with only 62% ownership of at least one mosquito net and only 37% of children using the nets. This seeks to investigate the willingness to buy and the use ITN use among caregivers of under five children attending immunization clinic in Bingham University Teaching Hospital. Methodology: A descriptive cross sectional study design carried out among 242 caregivers of all ages and sex of under-five children attending immunization clinic at Bingham University Teaching Hospital (BHUTH) in Jos North Local Government Area of Plateau State, Nigeria. A Simple Random Sampling technique was used to select respondents. Findings: Two hundred and sixteen 216 (89.3%) of the children use ITNs, majority of the children 190 (78.5%) slept under ITN the night before the interview, 226 (93.4%) owned ITNs, 156 (64.5%) got the ITNs for free while 60 (24.8%) paid for it and majority 172 (71.1%) of the children use ITN every night. Tertiary education, having much younger children (less than 3 years) and perception as a means of malaria prevention were associated with higher use of ITNs. Majority 220 (90.9%) the caregivers were willing to buy ITN and also recommend ITN to others. Caregivers who were traders and civil servants were willing to buy ITN than farmers, tertiary education, having children 1 - 3 months old, and owning 3 or more ITNs was associated with willingness to buy ITNs. Conclusion: About 90% of the children of caregivers use ITNs and over three quarters slept under ITN the night before the interview and majority use it every night. Majority the caregivers were willing to buy ITN and also recommend ITN to others. The government and health care workers should continue to encourage and enlighten caregivers to keep using ITNs for their children and sustain mass free distribution of ITNs to improve ownership and utilization of ITNs.
Improving student retention through scholarly development

Student retention is an important issue, from the deeply personal level of individual students to a higher education system level of national or even global scale. There are many motives for higher education institutes to improve their student retention – their ability to retain students and enable them to graduate. Large drop out numbers can be connected to quality problems and affect both reputation and recruitment in a negative way. This has lead to a great number of interventions to improve student retention. However, many of these are based on hunches, traditions and taken-for-granted assumptions. For example, the ATTRACT-project found that less than one fifth of surveyed retention initiatives built on a scholarly foundation (Andersson, Gelin & Marklund, 2011). Routines and practices for addressing student retention issues in a research-based fashion with a strong connection to the local context have been developed at the faculty of science and technology at Uppsala University. The process started a decade ago, when initiatives based on feelings and assumptions failed to affect student retention. A strong scientific base for new initiatives was constructed on relevant research, such as the work of Tinto (1997) and Yorke & Longden (2004). Questionnaire and interview studies were utilized to explore the local context, drawing on international research. Important areas for action were identified, such as the process of academic integration, and different initiatives were developed. Evaluation showed that some of these directly had a large impact on improving student retention. Successful initiatives, as well as the scientific foundation for these, has spread between educational programmes and institutes through communication and collaboration. We present and discuss this development process.
Sources, Sinks, and Population Regulation

Animal and plant populations often occupy a variety of local areas and may experience different local birth and death rates in different areas. When this occurs, reproductive surpluses from productive source habitats may maintain populations in sink habitats, where local reproductive success fails to keep pace with local mortality. For animals with active habitat selection, an equilibrium with both source and sink habitats occupied can be both ecologically and evolutionarily stable. If the surplus population of the source is large and the per capita deficit in the sink is small, only a small fraction of the total population will occur in areas where local reproduction is sufficient to compensate for local mortality. In this sense, the realized niche may be larger than the fundamental niche. Consequently, the particular species assemblage occupying any local study site may consist of a mixture of source and sink populations and may be as much or more influenced by the type and proximity of other habitats as by the resources and other conditions at the site.
Digestibility of threonine from protein concentrates for growing pigs. 2. The digestibility of threonine to the terminal ileum in pigs given six protein concentrates

Six male Landrace x Large White pigs (25 kg liveweight) were fitted with T-shape cannulae in the terminal ileum. The pigs were fed 1.2 kg dry matter per day containing 4.5 g threonine/kg of diet from continuous belt feeders. The apparent digestibility of dry matter (DM) to the terminal ileum was 0.91, 0.87, 0.85, 0.81, 0.80 and 0.75 for pigs given diets containing milk, fish meal, soybean meal, meat meal, sunflower meal and cotton seed meal respectively. The apparent digestibility of nitrogen (N) to the terminal ileum was 0.87, 0.87, 0.86, 0.86, 0.81 and 0.74 for pigs given diets containing milk, fish meal, soybean meal, sunflower meal, meat meal and cottonseed meal, respectively. The true digestibility of threonine to the terminal ileum was 0.96, 0.95, 0.90, 0.87, 0.80 and 0.66 for the diets containing milk, fish meal, sunflower meal, soybean meal, meat meal and cottonseed meal, respectively.
The Marketing Factors Affecting Student’s Decision of Choosing Higher Education Institution in South- Northeastern Region

This research is to examine the marketing factors that affect student’s behavior in decision making of choosing higher education institution under the Higher Education Commission in the south-northeastern region totally 7 provinces which consists of Sri Saket, Burirum, Chaiyaphum, Nakhon Ratchasima, Surin, Nongbau Lamphu and Ubon Ratchathani. The results of this study based on its objectives are as followed. 1) To study the marketing factors that affecting student’s decision of choosing higher education institution in the Southnortheastern region, after testing the relationship between marketing factors and the institution type of selection tested with the chi square ( 2 χ ), found that product, price, distribution channels, people and physical evidence have relationship with institution type of selection at 0.05 significance level and promotion is associated with institution type of selection at 0.10 significance level. But process of service providing has none relationship with any institution types selection. 2) To study the personal factors; income of the parent, domicile of the family, occupation of the parents, and education level of parents of students that affect student’s decision in choosing higher education institution in the Southnortheastern region, the result of testing the relationship between personal factors to institution type tested with the chi square ( 2 χ ) at 0.05 significance level, found that personal factors, which are parent income, family domicile, father's and mother's occupation, and level of education, affect the selection of institution type. Thus, in order to set institution’s marketing policies and strategies, different types of institution should consider the differences between personal factors and focus on improving to differentiate marketing strategies. So that the institution will fulfill perspective student needs effectively which will enables organizations to insistent operate under highly competitive circumstance in the future.
Board Attributes and Firm Performance: Tunisian Evidence

This study examines the relationship between board attributes and firm performance. In accordance with agency theory, effective board of directors plays a key role in establishing good corporate governance and enhancing firm performance by mitigating earnings management. Based on panel data set drawn from Tunisian listed firms over the period 2011 – 2017 and while using dynamic panel GMM estimator to alleviate endogeneity problems, a U-shaped relationship was found between board size, board independence and firm performance. Indeed, results show that a higher firm performance is confirmed if the board size is composed of at least 6 members and 15% of independent board members. For a robustness check, this study measures a composite score of the effectiveness of board of directors to capture the aggregate impact of board’s effectiveness on firm performance. The findings of regression analysis find a significant positive relationship between the board effectiveness score and firm performance. Indeed, there is a synergy between mechanisms that act together to enhance firm performance in the Tunisian context.
Karyotype and banding analyses on haploid males of the honey bee (apis mellifera).

Chromosomes of spermatogonial cells from young larvae of Apis mellifera were analyzed by means of G- and C-banding techniques. They consist of 4 meta-centrics and 12 submeta- or subtelo-centrics. G-banding patterns so far as no. 1 to no. 6 and no. 14 to no. 16 were concerned, they were stably distinguished.Nos. 2, 3, 4, 6, 7 and one from no. 8 to no. 16 showed C-bands. Even with these banding techniques, no sex chromosomes were found in this study.
Angiotensin Converting Enzyme 2 in Coronavirus Disease (COVID-19): Evidence from Bioinformatics Analysis

Recently, the outbreak of coronavirus disease 2019 (COVID-19) is threatening human health globally. There is a dire need to find potential therapeutic agents. Angiotensin converting enzyme 2 (ACE2), as an entry receptor of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is considered as potential therapeutic target in COVID-19 pandemic. Here, our bioinformatics analysis revealed that the biological function of ACE2 was correlated with regulation of blood pressure and mediation of SARS-CoV-2 entry into host cells. Ten ACE2 cooperative proteins were identified by using STRING with a high score. ACE2 expressed highly in the small intestine, testis, and kidney. The level of ACE2 expression in tumor tissues varies in different types of cancers compared with that in normal tissues. It was worth noting that the expression level of ACE2 in the tumor has no effect on patient survival. MiRNA hsa-miR-942-5p, and three transcription factors (TFs) including Signal transducer and activator of transcription 4 (STAT4), Estrogen related receptor α (ESRRA), and Signal transducer and activator of transcription 3 (STAT3) were selected as novel ACE2 regulators. Moreover, nine potential therapeutic drugs were predicted by two online databases. Thus, our research may expand the overall view of ACE2 in COVID-19 treatment.
