Induction of Superovulation in Acutely Hypophysectomized Rats and Presence of Ovulable Population of Follicles.

Superovulation was induced in intact and acutely hypophysectomized mature rats by a successive eCG-hCG treatment. In the rats hypophysectomized after the onset of GTH surges, increment in eCG dosages maximized the number of ova shed by the following hCG treatment, and the maximum number was similar to those in non-hypophysectomized rats. In the rats hypophysectomized before GTH surges, however, the number of ova shed was significantly less, but this decrease was restored by an hCG injection immediately after the hypophysectomy. These results indicate that the maximum number of ova shed is determined by the limited number of eCG-responsive follicles that are generated during exposure to an antecedent LH surge. In intact rats, excess doses of eCG elicited enhanced progesterone secretion which, in turn, established PRL surges. These PRL surges appears to cause atretic changes in growing follicles and decreased the number of ova shed by the following hCG treatment. Thus, the upper limit of the number of ova shed in mature cycling rats subjected to the eCG-hCG treatment was estimated to be approximately 80.
Engagement Marketing: the Innovative Perspective to Enhance the Viewer’s Loyalty in Social Media and Blogging E-Commerce Websites

The purpose of this paper is to examine the impact of three dimensions of Blog service innovation (system operation, social technology & diversification) on website viewers' online loyalty through the intervening effect of two aspects of online relationship quality (trust & satisfaction) in the context of social media and blogging websites. A sample of 251 social media and blogging sites users responded to a structured questionnaire adapted from existing literature. First, confirmatory factor analysis was carried out, and then data were analysed through structural equation modelling using the bootstrap methodology in AMOS 24. The findings indicated that two innovations (system operations & diversification) indirectly affect the website viewers' online loyalty through both Trust and Satisfaction. In contrast, Social Technology related innovation affects website viewers' online loyalty only through Trust. Further, none of those mentioned above innovations has a direct relationship with the website viewers' online loyalty. This paper explains the loyalty pattern of social media and blogging website users following the changes in services provided by organizations in their websites, which is explicitly mediated through online relationship quality factors. From a managerial perspective, the study does only provides the vital information on user's behaviour in relationship to the innovations in services introduced by organizations in their websites but also reveals that it can help them to minimize their cost and maximize their profits through value creation to the target audience. This paper is first of its kind to investigate the relationship between different dimensions of blog service innovations and website viewers' online loyalty mediated through two dimensions of online relationship quality. Although different studies focused on the enhancement of online loyalty factors through trust and satisfaction, no study was afforded to the blog service innovation perspective which includes innovations related to System operations, Social technology and Diversification especially in the context of social media and blogging website users. Keywords service innovation, social media, blogging, online relationship quality, trust, satisfaction, online loyalty, e-loyalty.
The relationship of tropical bird communities to tree species composition and vegetation structure along an Andean elevational gradient

Understanding patterns of species turnover along environmental gradients and their consistency across taxonomic groups is central to the study of biodiversity. We may expect congruence in diversity patterns across groups whose ranges could be influenced by species interactions. We explore associations between bird and vegetation communities in the tropical Andes to determine whether patterns of species richness and turnover in birds and trees are congruent with elevation, and whether tree species composition, vegetation structure, elevation, or a combination of these best predicts bird species composition.
The Effects of Market Competition, Capital Structure, and CEO Duality on Firm Performance: A Mediation Analysis by Incorporating the GMM Model Technique

This current study is one of the few investigations to conduct a focalized examination of the relationship between CEO duality and firm performance; however, this relationship seems to be imprecise due to the impact of the invention mechanism. This study explores the effect of CEO duality to achieve firm performance through the mediating effects of capital structure and market competition, which is an innovative model. The study incorporated the generalized method of moments (GMM) model to examine the proposed association of the CEO duality and firm performance, and the findings specified a negative relationship between CEO duality and firm performance. The results indicated that capital structure partially mediated the association between CEO duality and firm performance. The results also showed that market competition fully mediated this linkage between CEO duality and firm performance, which in turn specified a significant positive relationship with market competition, which mediated a positive relationship. By incorporating these mediators, the results determined that CEO duality reduces firm performance through the capital structure; however, it enhances firm performance by stimulating market competition.
Provision of Teaching and Learning Materials that Enhance Participation of Students with Special Educational Needs in Inclusive Schools at Pokuase in the Greater Accra Region

The study focused on investigating teaching and learning materials teachers provide to enhance participation of students with special educational needs in teaching and learning at Pokuase in the Greater Accra Region of Ghana. The study employed the descriptive survey design. Purposive and simple random sampling techniques were used to select the sample size of 112 respondents. Descriptive statistical method was used to analyse questionnaire data for the study. Results from the study revealed that, teachers provide teaching and learning materials of all kinds during teaching and learning. However, some of these materials do not cater for the unique needs of all learners especially those with special educational needs. Instructional materials such as tape recorders and text in braille were not provided, computers were not adapted to enhance easy access for pupils with special educational needs. The study recommended that teachers provide materials to include tape recorders, text in Braille, materials that are bold with good colour contrast and adapted computers for easy access especially to those with special educational needs . Purpose of the study The study sought to investigate teaching and learning materials teachers provide to enhance learning among pupils especially those with special educational needs in inclusive classrooms. Keywords: provisions, special educational needs, teaching and learning materials, assistive technology. DOI: 10.7176/JEP/11-4-01 Publication date: February 29 th 2020
A Multilayered-and-Randomized Latent Factor Model for High-Dimensional and Sparse Matrices

How to extract useful knowledge from a high-dimensional and sparse (HiDS) matrix efficiently is critical for many big data-related applications. A latent factor (LF) model has been widely adopted to address this problem. It commonly relies on an iterative learning algorithm like stochastic gradient descent. However, an algorithm of this kind commonly consumes many iterations to converge, resulting in considerable time cost on large-scale datasets. How to accelerate an LF model's training process without accuracy loss becomes a vital issue. To address it, this study innovatively proposes a multilayered-and-randomized latent factor (MLF) model. Its main idea is two-fold: a) adopting randomized-learning to train LFs for implementing a ‘one-iteration’ training process for saving time; and 2) adopting the principle of a generally multilayered structure as in a deep forest or multilayered extreme learning machine to structure its LFs, thereby enhancing its representative learning ability. Empirical studies on six HiDS matrices from real applications demonstrate that compared with state-of-the-art LF models, an MLF model achieves significantly higher computational efficiency with satisfactory prediction accuracy. It has the potential to handle LF analysis on a large scale HiDS matrix with real-time requirements.
Incorporating IEEE 1609.2-2016 Standard with Internet of Things-Based Low Power WAVE Devices

The integration of low-power devices in different aspects of life has increased the challenges of mitigating the impact of the heterogeneity of different related technologies. Accordingly, the Internet of Things context is an umbrella that diffuses different proprietary protocols into standardized forms to overcome the heterogeneity problem. The recent IEEE 1609.2-2016 standard is tackling the issue of wireless access security in the vehicular environment. An obstacle arose by which Internet of Things-based, low-power devices are integrated into the Internet of Vehicles cloud. In turn, the overhead of Internet of Vehicles-based protocols must be analyzed regarding the adaptability of low-power devices in the vehicular environment. This paper investigates the burden of the IEEE 1609.2 security stack on Internet of Things-based, limited-capability devices and defines the possible approaches to incorporate these low-power devices within the vehicular network under the IEEE 1609.2 standard. The proposed methodology, through the conducted simulations, demonstrates low security overhead with a 40% reduction in consumed energy over the default WAVE stack. In addition, the results show that including low-power devices within the Internet of Vehicles paradigm is possible, but still more enhancements and contributions are required to minimize the overhead of the WAVE security stack.
Failure of Eucalyptus globulus (Labill.) plantations on previously irrigated pasture sites in south-eastern South Australia

Summary From the mid-1990s onwards large areas of Eucalyptus globulus (Labill.) were planted in south-eastern South Australia and south-western Victoria (the Green Triangle region) on land which had been under pasture for decades. Within these plantations some well-defined areas had poor tree growth, and in extreme cases trees died in circular patches. The geometry of the affected areas strongly suggested an association with previous irrigation practices: very clear boundaries separated healthy and affected trees. Foliar analyses of both healthy and affected trees indicated adequate levels of most major nutrients (N, P, K and Ca). There were, however, marked differences in foliar manganese concentrations. Analysis of soil from previously irrigated areas showed increased soil bicarbonate concentration and pH compared to soil from areas with no history of irrigation. There was a strong negative correlation between soil pH and DTPA-extractable manganese. Concomitantly, foliar manganese concentrations decreased significantly to deficient levels as the soil-extractable manganese decreased. We conclude that the severe growth problems in E. globulus commonly found in circular patches of previously irrigated areas are due to acute manganese deficiency as a result of increased soil pH caused by irrigation with water containing high levels of bicarbonate. At one site where pasture grass was analysed, manganese concentration in pasture was considerably lower than in pasture from unirrigated areas, suggesting there could be problems in future for other crops in the region receiving repeated irrigation. The evidence that the pre-planting history dramatically influenced the growth of E. globulus plantations is important because plantations were not irrigated after planting, and areas of current eucalypt plantations in the region include land which had been under irrigation.
Morphometric and genetic variation of small dwarf honeybees Apis andreniformis Smith, 1858 in Thailand

The small dwarf honey bee, Apis andreniformis, is a rare and patchily distributed Apis spp. and is one of the native Thai honey bees, yet little is known about its biodiversity. Thirty (27 Thai and 3 Malaysian) and 37 (32 Thai and 5 Malaysian) colonies of A. andreniformis were sampled for morphometric and genetic analysis, respectively. For morphometric analysis, 20 informative characters were used to determine the variation. After plotting the factor scores, A. andreniformis from across Thailand were found to belong to one group, a notion further supported by a cluster analysis generated dendrogram. However, clinal patterns in groups of bee morphometric characters were revealed by linear regression analysis. The body size of bees increases from South to North but decreases from West to East, although this may reflect altitude rather than longitude. Genetic variation was determined by sequence analysis of a 520 bp fragment of the mitochondrial cytochrome oxidase subunit b (cytb). DNA polymorphism among bees from the mainland of Thailand is lower than that from Phuket Island and Chiang Mai. Although two main different groups of bees were obtained from phylogenetic trees constructed by neighbor‐joining and unweighted pair‐group method using arithmetic averages programs, no clear geographic signal was present. Thus, while the minor group (B) contained all of the samples from the only island sampled (Phuket in the south), but not the southern mainland colonies, it also contained samples from the far northern inland region of Chiang Mai, other samples of which were firmly rooted in the major group (A).
Towards a Chatbot for educational and vocational guidance in Morocco: Chatbot E-Orientation

Chatbots are currently used in various online applications; often for shopping or as a personal assistant. These chatbots offer a range of potential benefits, including personalization and 24/7 instant availability. These positive aspects of chatbots lend to applications in the educational sector. they represent a new type of human-machine interface in natural language. However, chatbots in academia have received only limited attention, for example by providing organizational support for studies or courses and exams. This branch of research is just emerging in the scientific community, therefore, in our article, we set up a chatbot in the field of educational and professional guidance which is based on the theory of John Holland and the RIASEC questionnaire in order to determine the dominant type of personality of undergraduate and graduate students that wants to enter the job market .
Your Next Move: Improving the health of middle-aged men who are overweight or obese

Received Date: Apr 16, 2020 / Accepted Date: Apr 23, 2020 / Published Date: Apr 24, 2020 Abstract Background: Your NeXt Move: X Fans in Training Program is a healthy lifestyle program tailored for men who are overweight or obese and was based on another intervention implemented in an urban setting. The goal of ‘Your NeXt Move’ was to improve men’s health through exercise and health literacy-based lessons using humor and competition to facilitate positive lifestyle changes. This paper shares the efficacy of the 12-week program regarding: weight, body mass index, waist circumference, blood pressure and physical activity in 35 to 65-year-old men who were overweight and obese living in a rural area. Methods: 25 men (49.4±8.3 yrs) provided data for this study. Results: Upon program completion, these men experienced, on average, a significant decrease in body weight (2.1 kg, p=0.006), BMI (0.7 kg/m, p=0.006), waist circumference, (3.6 cm, p=0.007), and systolic (7.7 mmHg, p=0.007) and diastolic (4.3 mmHg, p=0.036) blood pressure. They also, on average, increased their daily steps by about 2000, indicating improved levels of physical activity. Conclusion: These findings suggest ‘Your neXt Move’ was successful in improving the physiological health of the men who participated.

Treatment Persistence with TNF Blocker in Korean Rheumatoid Arthritis Patients

Objective. To estimate drug persistency and the safety of TNF blocker in Korean patients with rheumatoid arthritis. Methods. Data were extracted from medical records of rheumatoid arthritis patients who had treated with TNF blocker or are currently using TNF blocker at Hanyang University Hospital for Rheumatic Diseases from December 2000 to November 2009 (REtrospective study for Safety and Efficacy of Anti-RA treatment with biologiCs, RESEARCh). Comprehensive chart reviews were undertaken on all patients and data on drug usages and response of TNF blocker was collected at initiation, 3 months and the time of data collection. Persistency with treatment was examined using life-table analysis and multivariate Cox proportional hazard models were developed to examine potential predictors of discontinuation of TNF blocker. Result. A total of 268 patients were enrolled in this retrospective study. Among them 180 patients were included in the analysis of drug persistency. The 1-year and 5-year drug persistency of TNF blocker was 74% and 46%, respectively. Concomitant use of methotrexate (hazard ratio 0.46, 95% CI 0.27-0.80) was associated with higher persistence. Comparing to etanercept, adalimumab is an independent risk factor for discontinuation (hazard ratio 2.63, 95% CI 1.43-4.84). Conclusion. Five-year drug persistency of TNF blocker was 46% and concomitant use of methotrexate is associated with higher persistence.
KINETICS OF GROWTH AND DEATH IN ANABAENA FLOS‐AQUAE (CYANOBACTERIA) UNDER LIGHT LIMITATION AND SUPERSATURATION

The kinetics of population growth and death were investigated in Anabaena flos‐aquae (Lyngb.) Bréb grown at light intensities ranging from limitation to photoinhibition (5 W·m−2 to 160 W·m−2) in a nutrient‐replete turbidostat. Steady‐state growth rate (μ, or dilution rate, D) increased with light intensity from 0.44·day−1 at a light intensity of 5 W·m−2 to 0.99·day−1 at 20 W·m−2 and started to decrease above about 22 W·m−2, reaching 0.56·day−1 at 160 W·m−2. The Haldane function of enzyme inhibition fit the growth data poorly, largely because of the unusually narrow range of saturation intensity. However, it produced a good fit (P < 0.001) for growth under photoinhibition. Anabaena flos‐aquae died at different specific death rates (γ) below and above the saturation intensity. When calculated as the slope of a vx−1 and D−1 plot, where vx and D are cell viability (or live cell fraction) and dilution rate, respectively; γ was 0.047·day−1 in the range of light limitation and 0.103·day−1 under photoinhibition. Live vegetative cells and heterocysts, either in numbers or as a percentage of the total cells, showed a peak at the saturation intensity and decreased at lower and higher intensities. The ratio of live heterocysts to live vegetative cells increased with intensity when light was limiting but decreased when light was supersaturating. In cells growing at the same growth rate, the ratio was significantly lower under light inhibition than under subsaturation and the cell N:C ratio was also lower under inhibition. The steady‐state rate of dissolved organic carbon (DOC) production increased with light intensity. However, its production as a percentage of the total C fixation was lowest at the optimum intensity and increased as the irradiance decreased or increased. The rate and percentage was significantly higher under photoinhibition than limitation in cells growing at the same growth rate. About 22% of the total fixed carbon was released as DOC at the highest light intensity. No correlation was found between the number of dead cells and DOC.
The Treatment of Hairy‐Cell Leukemia with 2′‐Deoxycoformycin

Five patients with hairy-cell leukemia (HCL) and accompanying panctyopenia received three weekly treatments with 2'-deoxycoformycin (dCF, 4 mg/M2, i.v.), which was followed thereafter by treatments at threeto four-week intervals. These patients have been followed for 2 to 11 months, and their clinical features before and following therapy are shown in TABLES 1 and 2, respectively. One patient had been splenectomized and two patients had minimal splenomegaly, and their bone marrows showed greater than 90% replacement with HC. Normal peripheral blood counts (granulocyte count greater than l,000/mm3, platelet count greater than IOO,OOO/mm', and hemoglobin level greater than 11 g/dl) were obtained at 2 months, and have to date been maintained for 2, 5, and 9 months. One patient has complete, and two patients greater than 50% marrow clearing of HC. In two patients with massive splenomegaly there was a 50% and 70% reduction in the spleen size at 2 and 4 months, respectively, and concomitant improvements in the peripheral blood counts. Although dCF did not depress the granulocyte or platelet counts, there was a 1-3 g/dl decrease in the hemoglobin levels in all patients with the initial three treatments. The latter finding may reflect inhibition of marrow erythropoiesis by dCF, as there was no biochemical evidence of hemolysis. Moderate nausea / vomiting and associated lethargy, occurring 24 hours following dCF therapy, was observed in 80% of the patients. The incidence and severity of this toxicity increased with the number of initial weekly treatments, but therapy was well tolerated when dCF was administered on a three to four weekly basis, and continued to effectively reduce the marrow HC population or the degree of splenomegaly. The plasma deox yadenosine and adenosine levels were measured by reverse-phase HPLC' 24 hours after the first three treatments, and ranged from 0.5 to 2.2 p M and 0.8 to 4.6 pM, respectively. There was no consistent increase in the levels of these nucleosides with the number of weekly treatments, and no correlation between the levels and the incidence or severity of nausea/vomiting. In one patient the peripheral HC dATP content, as measured by a DNA polymerase assay: was initially less than 1 pmol/106 cells, and rose to 240 and 560 pmol/lo6 cells, respectively, 24 h after the first two weekly treatments, although the plasma deoxyadenosine levels at these times were only 0.6 and 1.6 pM, respectively. Concomitantly, the peripheral HC count decreased from 8,300 to 1,500 cells/mm3 2 weeks after the initiation of therapy.
