Margin trading shareholder activists

ABSTRACT We examine margin trading activists that we define as shareholders that are identified by Schedule 13D filings and state therein that they may use margin borrowings to finance their holdings. We find that arrivals of margin trading activists are associated with positive target announcement returns compared to those of non-margin trading activists. This indicates that margin trading activists’ arrivals are perceived as signals of positive future target firm performance. Moreover, we find that their investment horizon is likely contingent on how long they have invested in the targets prior to their filings or whether markets react positively to their arrivals.
Risk Factors of Maternal Mortality in Calabar

Maternal mortality remains unacceptably high despite both local and international programs carried at reducing the incidence. Nigeria suffers from 800 maternal death per 100,000 births. This study examines the extent to which cultural practices and quality of medical care determines maternal mortality in Calabar, Cross River State. Using the survey research design, data were collected from 400 women aged between 15 and 49 from Calabar using a self-developed structured questionnaire. The participants were selected using cluster and purposive sampling technique. Data collected from the field was analyzed using descriptive statistics and regression analyses at 0.05 confidence level. Result from the analysis revealed that uncivilized cultural practices lead to high maternal mortality. 75.64 per cent of the participant reported cases of complications during birth in the hands of traditional birth attendants. cultural practices account for 49 per cent of the variation in maternal mortality. Also, result revealed that poor care delivery or quality of medical care leads to high maternal mortality. 54.14 per cent of the participants reported that the cost of medical care for a pregnant woman in the hospital is too expensive. 69.43 per cent reported there have been deaths as a result of lack of care in hospitals. Based on these findings There is need for the government and its health ministry to increase the number of primary health centres in the nation as well as strengthen this health centres to collect high-quality data to respond to the needs and priority of women and girls amongst others.
Cost modelling of onboard cobot-supported item sorting in a picking system

ABSTRACT For manual picking processes in warehouses and assembly line feeding, collaborative robots – cobots – hold a potential to support operators and, thereby, enhance performance. However, studies focused on the economic aspects of cobot applications have been scarce. The present paper aims at modelling a new picking system, in which human operators collaborate with cobots during picking (or kitting) activities. It is considered the case of having a cobot on board of the picking trolley or cart, working in parallel with the picker by performing sorting of the picked items. The paper focuses on the economic aspects of this application and presents a model of the relative cost difference between a manual and a cobot-supported process, accounting for the costs associated with operators, equipment, and quality. The relative cost difference is analysed in a numerical example. The findings suggest that the decision to use a cobot sorting mode is robust when there is considerable sorting work to carry out, for example, when there are higher yearly order volumes to handle, and when higher order commonality among orders processed as a batch can be achieved. Future research should focus on implementation challenges and safety issues associated with cobot-supported picking processes.
Antifungal Activity of Gelatin-Tapioca Starch Film and Coating Containing Copper Nanoparticles against Colletotrichum gloeosporioides Causing Anthracnose

This study aimed to fabricate a nontoxic coating containing copper nanoparticles (CuNPs) to protect fruits from pathogenic Colletotrichum gloeosporioides causing anthracnose on several tropical fruits. We used a green approach, in which CuNPs were synthesized by reducing CuSO4 with ascorbic acid in the presence of gelatin and glycerol as the capping agents. The formation of CuNPs was confirmed by UV-vis absorption spectra of the reaction mixture, which showed a surface plasmon resonance peak at 578–594 nm. The x-ray diffraction spectrum of the CuNPs indicated the presence of mostly metallic copper with some minor impurities of Cu2O, CuO, and Cu(OH)2. Transmission electron microscopy (TEM) images and dynamic light scattering studies showed that the sizes of 90% of CuNPs were in 100–300 nm range. A 30–50 nm capping layer of gelatin surrounding CuNPs can be observed in the TEM images. Comparing FTIR spectra of the used reagents and CuNPs confirmed the depletion of ascorbic acid, as well as the gelatin layer protecting CuNPs. The synthesized CuNPs showed dose-dependent antifungal activity against C. gloeosporioides with 100% growth inhibition at 200 ppm copper. Gelatinized tapioca starch was then added to the CuNPs solution to obtain a film-forming mixture to produce stand-alone composite films on Petri dishes and coatings on mangoes. C. gloeosporioides could not grow on the surface of nutrient agar in contact with the films containing 245 ppm CuNPs, while they grew normally on control films without CuNPs. For the in vivo antifungal tests on mangoes, both the control and the CuNPs-containing coatings equally inhibit fungal growth, possibly due to the low oxygen permeability of the protein and starch components in the films. This study thus demonstrated the potential applications of composite coatings using biodegradable polymers that contain CuNPs in postharvest protecting fruits from phytopathogenic fungi.
Integrated Approach for the Management of Chilli Leaf Curl Virus (ChiLCV) Disease of Chilli (Capsicum annuum L.)

Chilli leaf curl virus (ChiLCV) disease caused by Begomovirus (family Geminiviridae) has emerged as a serious threat to the successful cultivation chilli (Capsicum annuum L.) production in India and worldwide, which is drastically decreases yield. An integrated approach was developed for the management of ChiLCV disease of chilli using strategies such as growing border crop, use of reflective mulches, soil application of organic amendment and the spray of insecticides for management of the vector. The results of the experiments from the three years pooled data, pesticides with label claims, yield and cost-benefit ratio indicated that treatment comprising application of neem cake @ 1.0 kg/m 2 in the seedbed, covering of nursery with 40 mesh white nylon net, spraying of Cyantraniliprole 10.26 OD @ 1.2 ml/l three days before transplanting, seedling dip of Imidacloprid 17.8 SL @ 0.5 ml/l and planting of two rows of maize border crop in the main field along with sliver agrimulch sheet and the spray of Cyantraniliprole 10.26 OD @ 1.2 ml/l at seven days interval till fruit formation was found significantly superior over control in terms of per cent leaf curl incidence (4.02 %) and green fruit yield (136.40 q/ha) with better cost-benefit ratio (1:2.10). This integrated approach is safe and ecologically sound and seems to be a healthy tactic for disease management.
Edu-Finance Management Model in BOS Fund Management to Create Financial Well-Being

The purpose of this study is to analyze the implementation of BOS fund management and to design an edu-finance management model in order to achieve school financial well-being. The research approach used was a qualitative approach. Data sources consisted of BOS fund managers and school principals. Data collection techniques included FGDs with BOS fund managers; interview; and documentation. Data analysis techniques used the Miles and Hubermans model including data reduction, data presentation and drawing conclusions and verification. The conclusion of this research is that the compilers of school financial planning and work programs are made only to fulfill administrative requirements; the implementation of financial management in the management of BOS fund is still low; in making accountability reports, many do not understand the evidence documents that must be prepared and financial management training has not been carried out in accordance with the needs. After being given edu-finance training, the BOS fund managers understand the preparation of work programs, the use of BOS fund based on a priority scale, and the preparation of accountability reports along with the files that should be prepared.
Changes in Learner (De)Motivation and Confidence : A Longitudinal Analysis of an Online-offline Blended English Program

This paper examines the longitudinal changes of Korean college students in their motivation and their self-confidence in an online-offline blended EFL-learning course. The participants completed the same questionnaire three times (i.e., March, June, and December) with items regarding the ideal second language (L2) self, the ought-to L2 self, instrumentality, integrativeness, demotivation, and the perceived confidence in speaking English. Repeated-measures t-test/ANOVA indicated that students’ initial motivation was maintained until the end of the academic year. Their confidence in speaking English increased in a statistically significant manner. However, student demotivation also increased despite the fact that it remained at a relatively low level. These findings portrayed that the online-offline blended English learning was an effective instructional medium for EFL students in their English courses. This study suggests that L2 practitioners need to find an optimal balance between online instruction and offline EFL classes, where in-class authentic L2 communication should be maximally fostered. online-offline college EFL course affects the English speaking confidence and English learning motivation of first-year students from a of and Education, same the intricate relationship between learners’ research in previous literature on the longitudinal effect of second language (L2) learning motivation and demotivation of college students taking an English language course where blended learning was applied. current study would contribute to a deeper understanding on the applicability of blended L2 instruction to the tertiary context.
Identity change, uncertainty and mistrust in relation to fear and risk of COVID-19

Abstract The COVID-19 pandemic produced threats not only to physical and psychological health but also to the very fabric of family, work and social life. Individuals differ markedly in their ability to cope with such threats. Drawing on Identity Process Theory, our study examines identity processes that shape emotional and attitudinal responses to COVID-19. Survey data were collected from 251 adults in the UK during July 2020. Identity resilience, trust in science and scientists, fear of COVID-19 and perceived own risk of infection were measured. Respondents then watched a video clip designed to focus their thinking further upon the disease. Immediately after, levels of feeling afraid, uncertainty about self-protection, mistrust of anyone offering COVID-19 advice, and perceptions of identity change were indexed. A structural equation model of the relationship between these variables was tested and proved a good fit for the data. Identity resilience is negatively related to fear of COVID-19, which in turn is positively related to perceived own risk of COVID-19. Lower identity resilience is associated with greater uncertainty and feeling more afraid. Greater identity change is associated with higher mistrust, uncertainty and feeling more afraid. Trust in science and scientists correlates positively with perceived own risk of COVID-19 and negatively with mistrust of those offering advice on preventive behaviour. This study shows the usefulness of the identity resilience concept in modelling responses to health hazards. It also illustrates that focusing, even for a short time, on the characteristics of such a hazard can elicit perceived identity changes. Arousing fear is unlikely to initiate self-protection in those who are already fearful or who have less identity resilience. Fostering greater general trust in science and scientists, though difficult, will be valuable, particularly in encouraging public acceptance of mass vaccination against the virus when misinformation and conspiracy theories about it abound.

Intersection between ageing-related Genes and SARS-CoV-2 Interactome: Is it higher than expected?

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection (coronavirus disease, 2019; COVID-19) is associated with adverse outcomes in patients. It has been observed that lethality seems to be related to the age of patients. Moreover, it has been demonstrated that ageing causes some modiﬁcations at a molecular level.Objective: The study aims to investigate a possible link between the increased COVID-19 lethality and the molecular changes that occur in elderly people.Methods: We considered publicly available datasets on ageing-related genes and SARS-CoV-2 interactors. Then, for each SARS-CoV-2 protein interactor, we tested for the enrichment of ageing-related proteins. Finally, we performed a network-based analysis to identify which molecular mechanisms could play a role in the SARS-CoV-2 molecular aetiology and ultimately affect COVID-19 outcome.Results: We observed a signiﬁcant intersection between some SARS-CoV-2 interactors and ageing-related genes. Our analysis evidenced that virus infection particularly affects ageing molecular mechanisms centred around proteins EEF2, NPM1, HMGA1, HMGA2, APEX1, CHEK1, PRKDC, and GPX4.Conclusion: Our study generated a mechanistic framework aiming at explaining the correlation between COVID-19 incidence in elderly patients and molecular mechanisms of ageing. This will provide testable hypotheses for future investigation on the mechanism of action of coronaviruses and pharmacological solutions tailored on speciﬁc age ranges.
What is There in a ‘Like’? Political Content in Facebook and Instagram in The 2019 Valencian Regional Election

Over the last few years, social networks such as Facebook and Instagram have become the preferred places for political communication. On the one hand, politicians have incorporated them into their strategy as a channel through which they can share their messages. On the otherhand, users have a space where they can take part and show their interest in political issues. This paper examines posts on Facebook and Instagram by the main Valencian political parties and their respective leaders in the election campaign. We analysed the nature of the content and users’ ‘likes’ to reveal the functions and themes of the most popular posts and the use made of visual resources and interaction tools. The results show that the positioning taken by politicians influences the content getting the most ‘likes’. While supporters of opposition parties are most pleased by critical messages, followers of pro-government parties prefer messages that focus on management success. At the same time, items focusing on social policies and election campaign issues are those that generate the most ‘likes’ among the public. Visual aids (such as photographs and videos) and hash tags and links help boost users’ approval.
Improved Pancreaticoduodenectomy Outcomes after Starting a Specialized Community Hospital Pancreatic Surgery Program

Background: Recent trends in centralization of pancreatic surgery happened as a response to improved outcomes in tertiary care institutions. The volume-outcome relationship is true for high volume hospitals and surgeons. Obstacles to patient travelling to high volume institutions and widespread quality care in community hospitals led to establishing a quality specialized pancreatic surgery program in the community. Methods: Two pancreatic surgery specialists relocated their program from a tertiary care center to a community hospital. Results of the first sixty-two pancreaticoduodenectomy and total pancreatectomy procedures were studied. Results: One hundred and seventeen pancreatic surgery cases were analyzed, sixty-two pancreaticoduodenectomy and total pancreatectomy cases were included. Patient demographics were not different in regard to the median age (67 vs. 62 years), gender (65 vs. 62% males), median BMI (26.2 vs. 26 kg/m2), or American Society of Anesthesiologists class, in between the two hospitals. There was a significant decrease in the operative time (350 vs. 281 minutes, p=0.0001), estimated blood loss (409 vs. 156 milliliters, p=0.003), and length of hospital stay (7.2 vs. 5.2 days, p=0.0001). Most patients were operated on for a diagnosis of malignancy (74.2%), and the R0 resection rate was better at the community hospital reaching 95.2%. Transfusions, delayed gastric emptying and leaks tended to be better at the community hospital but did not reach statistical significance. Conclusion: With dedicated institutional support and careful program design, complex procedures such as PD can be successfully relocated to the community where superior results can be achieved.
Supporting the emergence of mathematical knowledge through problem posing

Problem posing represents a valuable strategy to create a bridge between mathematics classroom activities and everyday-life experiences. Despite the value of problem posing activities as opportunities for measuring students’ mathematical learning outcomes, more research is needed in investigating if and how problem posing could support the introduction of new mathematical knowledge promoting the development of mathematical concepts . The aim of this paper is to start investigating how problem posing can extend students’ mathematical knowledge. After having introduced the notion of emergent problem posing, some results from a teaching experiment conducted in a primary school class are reported. The design of the teaching experiment was explicated through the development of the three components of a Hypothetical Learning Trajectory: learning goal ; hypothetical learning process ; learning activities . Results from the study indicate that semi-structured problem posing activities that start from a suitable artifact could support the emergence of new mathematical knowledge, supporting students’ in re-inventing mathematical strategies to solve problems posed by themselves. However, further research is necessary, especially in: supporting the notion of emergent problem posing with more teaching experiments; investigating the role of different artifacts in supporting the process of emergent problem-posing; evaluating which characteristics an artifact should have in order to support the process of emergent problem posing; examining possible relations between students’ abilities and emergent problem posing performances.
ASSESSMENT OF PREDICTIVE VALIDITY OF COLLEGE ENTRANCE EXAMINATION QUESTIONS (CEEQ) FOR 2014/2015 ACADEMIC SESSION AT BAYELSA STATE COLLEGE OF HEALTH TECHNOLOGY, OGBIA

Every test designed for purposes of admission is expected to possess psychometric properties of a test in order to address the social implications of tests. This study was aimed to determine the predictive validity of College Entrance Examination Questions (CEEQ) for 2014/2015 academic session. An expos-facto research design was used on a sample of 105 candidate entrance scores and Cumulative Grade Point Averages (CGPA) from seven programs of study. Data were obtained from the College Registry and various departments running the programs. Data collected were analyzed, using Microsoft Excel 2010 and Statistical Package for Social Sciences (SPSS) 20. Result of analysis showed that CEEQ score could predict students’ CGPA by 2.8% only. It was also determined that CEEQ has a weak but positive relationship with CGPAs (16.7%). On running the data on simple regression statistics revealed that the CEEQ do not predict CGPAs significantly as p =. 089 (P>.05). It was concluded that CEEQ was not valid hence recommendation was made that College management should look forward to develop a standardized test for admission purposes.
