WFA-Center for Finance and Accounting Research Working Paper No. 15/07 The Information in Fire Sales

Asset prices remain depressed for prolonged periods of time following mutual fund fire sales. We show that this price pressure from fire sales is partly due to asymmetric information which leads to an adverse selection problem for arbitrageurs. After a flow shock, fund managers choose to sell low-quality stocks. To measure this, we use short interest as a proxy variable for the unobservable negative signal managers use when selling. Following flow shocks, managers are significantly more likely to sell stocks which, ex ante, have high short interest. Moreover, these stocks experience future price drops that do not later reverse. In other words, fund managers have stock selling ability. Our findings suggest an explanation for the tendency of asset prices to remain depressed following fire sales: information asymmetries make it difficult for arbitrageurs to disentangle pure price pressure from negative information.

The Challenges Faced by The Agriculture Lectures in Improving Teaching Delivery at Malaysia Agriculture Vocational Colleges: A Competency Study

Received: 28 July 2020 This study was conducted to analyse the challenges faced by agricultural lecturers at the Agricultural Vocational College in Malaysia. The objectives of this study is to look into competence in terms of skills and educational practices of agricultural lecturers. Apart from that, this study also examines the obstacles that interfere with the achievement of lecturers' competence. This study was a quantitative study that used a set of questionnaires as a research instrument. The study sample was selected using stratified random sampling method proposed by Krejeie and Morgan. The respondents of this study consisted of 162 lecturers involving five agricultural stream vocational colleges in Malaysia. The data were collected using a questionnaire instrument and analysed using Statistical Package for the Social Science (SPSS version 24) software. The results from the analysis of this study revealed that there are obstacles that interfere with the level of competence of lecturers. Meanwhile, the level of skills of lecturers in achieving positive behaviour was at a moderate level with a mean score of 2.99. However, educational practices possessed by lecturers were at a high level with an overall mean score of 3.05.
International Journal of Medical and Biomedical Studies (IJMBS)

Background and Objectives: C‐reactive protein (CRP) is a type I acute phase reactant. A number of studies have reported elevated gingival crevicular fluid (GCF) CRP levels in periodontitis subjects, which decrease following periodontal therapy. Effect of diode laser as an adjuct to Scaling & Root planing is also well stablished. The aim of the present study was to evaluate the effect of periodontal treatment SRP with diode laser, on CRP levels in GCF in patients with chronic periodontitis. Materials and Methods: A total of 40 subjects with moderate periodontitis based on community periodontal index scores, were included in the study. Periodontal therapy was performed dividing each side of jaw as a group (Split mouth); one side SRP alone & another Diode laser with SRP. GCF was collected from each subject at Baseline (prior to treatment) and 1 month after periodontal therapy. The collected sample was subjected to biochemical analysis to detect CRP levels by using a commercially available highly sensitive kit. Results: The present study demonstrated that the mean CRP values at baseline were found to be 0.11043mg/l in side-I (side treated with SRP alone); 0.11042mg/l in side-II (side treated with SRP & laser) of the patient, which reduced to 0.4148 mg/L in side I and 0.3985mg/L in side II after treatment, which are highly significant according to statistical analysis but the changes between two sides were nonsignificant statistically. Interpretation and Conclusion: Within the limitations of this study, it can be concluded that periodontal therapy is able to reduce the GCF C reactive protein level significantly, but there was no statistically significant result in CRP level, between sides treated with SRP & SRP with laser.
Seasonal Variations in Semen Parameters of Zulu Rams Preserved at 10°C for 72 H During Breeding and Non-Breeding Season

The study was conducted to evaluate the seasonal variations in semen parameters of Zulu rams preserved at 10°C for 72 h. The study site was the Agricultural Research Council (ARC) Irene, during the breeding season and the non-breeding season. Zulu rams (n = 6, age = 3 years and average weight = 35 kg ±2.29) were used in this study. Semen was collected with the aid of artificial vagina. Macroscopic (volume and pH), microscopic (sperm concentration, progressions, velocities and velocity ratios and morphology) semen parameters were evaluated immediately after semen collection. Data were analyzed using General Linear Model (GLM) in Minitab 17®. Semen volume was higher during breeding season (0.97±0.25 mL) than non-breeding season (0.72±0.5 mL). Total sperm motility was higher (92.01±1.40%) at 24h during breeding season than non-breeding season (88.69±1.40%), thereafter declined drastically in both seasons. However, non-breeding season yielded a high progressive motility (50.86±1.63%, 33.77±1.63% and 27.56±1.63%) after 24, 48 and 72 h than breeding season (21.32±1.63%, 11.89±1.63% and 10.29±1.63%). It was concluded that, semen parameters from Zulu rams does vary with seasons. Nevertheless, despite seasonal variations observed, Zulu rams’ semen quality is acceptable in both breeding and non-breeding season hence can breed throughout the year. Notwithstanding, studies involving fertility are recommended and the nutrition effect of lambing during dry period should be considered.
FoxP3 Mediated Induction of Pim 2 Allows T Regulatory Cells to Preferentially Expand in Rapamycin

Addition of rapamycin to cultures of expanding T regulatory cells helps maintain their suppressive activity, but the mechanism behind this observation is unclear. Human pim 2, similar to murine pim 2, is a serine/threonine kinase that can confer rapamycin resistance. Unexpectedly, pim 2 was found to be constitutively expressed in freshly isolated, resting T regulatory cells but not in CD4 T effector cells, explaining why addition of rapamycin prior to T cell activation favors T regulatory cell expansion. Introduction of FoxP3, but not FoxP3Ä2, into effector CD4 T cells induced pim 2 expression and conferred preferential expansion in the presence of rapamycin, indicating that FoxP3 can regulate pim 2 expression and that functional differences do exist between the two prominent FoxP3 isoforms. Finally, we correlated the ability of natural T regulatory cells to expand with FoxP3 expression and observed positive correlation in the presence of rapamycin and a negative correlation in the absence of rapamycin. Together, these results indicate that T regulatory cells, because of their constitutive expression of FoxP3, are programmed to be resistant to rapamycin and this provides further rationale why this immunosuppressant drug should be used to augment T regulatory activity.
Occurrence of diapause in neotropical parasitoids attacking Anastrepha fraterculus (Diptera: Tephritidae) in a subtropical rainforest from Argentina

Incidence of diapause in neotropical parasitoid species associated with the tephritid fruit fly Anastrepha fraterculus (Wiedemann) infesting three major host plants collected from the southernmost end of Argentinean Yungas rainforest was studied. Three other objectives were the frequency of diapause according to the fruiting season of Prunus persica (L.) Batsch (peach), Psidium guajava L. (guava) and Juglans australis Grisebach (walnut); the length of diapause period for each recovered parasitoid species; and the proportion of diapausing parasitoid individuals that displayed prolonged diapause. Between 2001 and 2003, infested ripe fruits were weekly collected in wild vegetation areas. A portion of the fruit samples was processed at the same collection site. Recovered A. fraterculus puparia were kept under natural environmental conditions inside a wooden frame cage covered with a cloth mesh. The remaining halves of fruit samples were taken to the laboratory and puparia were kept under environmental controlled condition. Unenclosed puparia were kept for 2 years. Diapause period fluctuated between 131 and 426 days and was observed in all recovered parasitoid species (Doryctobracon areolatus (Szépligeti), D. brasiliensis (Szépligeti), Opius bellus Gahan, Utetes anastrephae (Viereck) and Aganaspis pelleranoi (Brèthes)). All diapausing individuals dissected from host puparia were instar III and were also remarkably different from non‐diapausing larvae because of their smaller body size. The 65% of all diapausing individuals was recorded in early autumn and was recovered from A. fraterculus larvae that had developed in guava. Prolonged diapause was recorded in a small fraction of the diapausing populations of D. brasiliensis, D. areolatus and A. pelleranoi. Results suggest that diapause is an adaptive mechanism that allows parasitoids to overcome periods of marked host scarcity given that guava is the last widely available host plant before the winter season begins.
Understanding Ethnicity and Cultural Affiliation: Huron-Wendat and Anthropological Perspectives

It is a well-known fact that archaeological cultures constructed by archaeologists do not always overlap with actual past ethnic groups. This is the case with the St. Lawrence Iroquoians of the Northeast. Up until recently, conventional narratives viewed this group as distinct from all other historic Iroquoian populations. However, the Huron-Wendat and the Mohawk consider themselves to be their direct descendants. Our paper is an attempt to reconcile oral history and archaeological interpretations by suggesting that part of the disparity between Huron-Wendat and archaeological conceptions of the group identity of the St. Lawrence Iroquoians lies in differential understandings of the very nature of ethnicity by each party.
Teachers, Curriculum Reform for Entrepreneurship Education in Nigeria: Issues and Consequences

Nigeria’s education sector is challenged with unqualified teachers, poor education infrastructures, outdated curriculum, poor policy commitment and lack of quality education. Furthermore, the targets set by the Sustainable Development Goals (SDGs) in 2015 expect countries around the world to achieve sustainable development in all sectors including education by 2030. Specifically, the SDG 4: Quality education for all and lifelong learning is expected to be achieved by national governments through their education systems in 13 years. This makes it paramount to examine Nigeria's education system and its challenges. Therefore, this research paper employed a literature review of relevant academic and policy research on teachers, curriculum reforms and entrepreneurship education in Nigeria. Additionally, a critical analysis of literature provided insights on issues and consequences of curriculum reform for entrepreneurship education in Nigeria. The findings of this paper reveal that teachers are agents capable of determining the success or failure of any educational reform. Furthermore, in Nigeria, curriculum reform for entrepreneurship education that was implemented failed to achieve set goals because of factors that were not considered by the government when making such reform. These factors include an inadequate understanding of teacher challenges, lack of adequate resources and poor policy commitment. This research paper concludes that for entrepreneurship development through curriculum reform to be realized in Nigeria, there is a need to improve teacher welfare and training, recognition of teachers' inputs in education reforms processes and provision of resources to effectively implement reforms.

REINFORCEMENT LEARNING ALGORITHM USING NEURAL NETWORKS FOR PLAYING OTHELLO

The paper presents a reinforcement learning algorithm using neural networks for learning an agent to play the Othello game. The system has no initial knowledge of the game, except of its rules. Reinforcement learning techniques allow an agent to learn successful game strategies by repeatedly playing the game. The only information received by the agent during learning is a reinforcement signal at the end of each game. Neural networks are known for their good generalization for untrained inputs. Since the state space for a game like Othello is very large, we use neural networks to represent the value function. The approach is similar to that of Tesauro for the game of Backgammon. The learned network can play Othello at a level close to that of expert programs as shown by its performance in world-championship games.
Ordering heuristics for k-clique listing

Listing all k-cliques in a graph is a fundamental graph mining problem that finds many important applications in community detection and social network analysis. Unfortunately, the problem of k-clique listing is often deemed infeasible for a large k, as the number of k-cliques in a graph is exponential in the size k. The state-of-the-art solutions for the problem are based on the ordering heuristics on nodes which can efficiently list all k-cliques in large real-world graphs for a small k (e.g., k ≤ 10). Even though a variety of heuristic algorithms have been proposed, there still lacks a thorough comparison to cover all the state-of-the-art algorithms and evaluate their performance using diverse real-world graphs. This makes it difficult for a practitioner to select which algorithm should be used for a specific application. Furthermore, existing ordering based algorithms are far from optimal which might explore unpromising search paths in the k-clique listing procedure. To address these issues, we present a comprehensive comparison of all the state-of-the-art k-clique listing and counting algorithms. We also propose a new color ordering heuristics based on greedy graph coloring techniques which is able to significantly prune the unpromising search paths. We compare the performance of 14 various algorithms using 17 large real-world graphs with up to 3 million nodes and 100 million edges. The experimental results reveal the characteristics of different algorithms, based on which we provide useful guidance for selecting appropriate techniques for different applications.
Overcoming hierarchy in business model innovation: an actor-oriented approach

Purpose Business model innovation is a key element for firms' competitiveness. Its development can be supported by the establishment of an actor-oriented scheme to overcome hierarchical structures. The actor-oriented scheme is characterized by intra-organizational networks of relationships that can be established and dissolved between individuals. However, we lack an empirical perspective about its establishment; therefore, the purpose of this research is to advance our understanding of intra-organizational networks for supporting business model innovation. Design/methodology/approach Individuals create and manage knowledge aimed to innovate the business model through cognitive search and experiential learning mechanisms. Knowledge is spread within organizations by using intra-organizational advice networks, whose patterns reflect the presence of an actor-oriented scheme. This work applies social network analysis to network data from a multi-unit organization specializing in personal care services. We use a Logistic Regression-Quadratic Assignment Procedure to analyze intra-organizational network data on managers' advice exchange related to the learning modes of cognitive search and experiential learning. Findings Our research empirically identifies the main elements of an actor-oriented scheme in a business model innovation process. We find that managers are able to self-organize, because they are not influenced by their organizational roles, and that commons for sharing resources and protocols, processes and infrastructures enable advice exchange, thus showing the presence of an actor-oriented scheme in business model innovation process. Research limitations/implications This research is based on a cross-sectional database. A longitudinal study would provide a better understanding of the network evolution characterizing the innovation process. Practical implications The results of our study support organizational decision-making for business model innovation. Originality/value This study provides empirical evidence of how an actor-oriented scheme emerges in a business model innovation process.
The place of Ndi-Igbo in Nigeria’s social and economic development

The advent of European colonialism radically altered the Igbo consciousness and compelled them to draw upon opportunities of the ‘new order’ to meet social and economic demands. The twentieth century was a period when the Nigerian people had to come to terms with the ‘new order’ introduced by their forceful integration into the global capitalist system. New music had been introduced; new dance steps were required. This study examines how the Igbo, in response to and in spite of, these dynamics carved a distinct place for themselves in Nigeria’s social and economic development. Indeed, the nature of the place of the Igbo vis-à-vis the country’s socio-economic evolution provokes intellectual fermentation. Are they taking their place in the sun or are they hewers of wood and fetchers of water in the Nigerian super structure? What factors have shaped their development? To what extent have external dynamics shaped the Igbo socio-economic factor? What are the omens for the future?
Impact of Entrepreneurial Involvement and Background on Entrepreneurial Intention of Undergraduates in Selected Universities in Southwest Nigeria

In recent times, due to limited job employment opportunities, low income, economic downturn of some developing economies amongst others, the desire to own a business or become self-employed has increased tremendously. Entrepreneurship focuses on the generation of an idea into a profitable venture. But the Intentions of such individuals are backed up with some notable orientations such as entrepreneurship education awareness, family background, environment, educational background and so on. This study examines the implication of entrepreneurship orientation on entrepreneurial involvement and background on one hand and how family background influence entrepreneurial intention on the other hand. The survey research design was adopted for the study under investigation. Students of some selected tertiary institutions in Oyo State (Lead City University and First Technical University, Ibadan) were randomly selected to form the population of this study. A randomized sampling method was adopted in choosing the population size for the study. 90 students were randomly selected from the First Technical University, Ibadan and 90 students from the Lead City University, Ibadan. Primary method of data collected was adopted for this study through the administration of structured questionnaire. Cronbach Alpha coefficients ranging from 0.781 to 0.892 was used to validate the questionnaire. The study also made use of relevant information from articles, journals and various online resources. Results from the study indicated that entrepreneurial orientation has a positive significant effect on entrepreneurial orientation of undergraduates and that significant relationship exists between family background and entrepreneurial intentions of undergraduate students. The study made recommendations to the university managements, university undergraduate students, young entrepreneurs, entrepreneurship educators and trainers, university based business incubators and the society at large.
Correlated Research on the Early Laying Performance of Erlang Mountain Chickens

Through the comparison of the laying performances and the analysis of the correlation among laying traits between the two strains of Erlang mountain chickens(SD02,SD03),the results showed that there were significant difference in the most of laying performances between the two strains,and the laying performance of the SD02 strain was much better than that of the SD03 strain.The age at first egg(AFE) was significantly in positive correlation with body weight at first egg(BWFE)(P0.01),and positively correlated with egg weight at first egg(EWFE)(P0.05). BWFE was in positively correlated with EWFE(P0.05),but negatively correlated with egg production at the fourth month after the first egg(P0.01). There was significantly positive correlation between the egg production in the first mouth;later egg production(P0.01).
ANALYSIS OF SERIES ELASTICITY IN LOCOMOTION OF A PLANAR BIPEDAL ROBOT

The great promise of series elastic actuation as an effective mean to improve the efficiency of dynamic bipedal locomotion is challenged by the difficulties in properly exploiting the dynamics of the system, due to the mutual influence between inputs and stiffness of the elastic elements. Although numerical optimisation has proven to be a valid tool to approach this problem, the contexts in which the energy improvement justifies the greater design effort are not clear yet. To fill this gap, this work presents an extensive numerical study in which optimised walking and running gaits are compared for a planar bipedal robot, driven either by rigid or series elastic actuators, whose stiffness is selected concurrently with the input trajectories. The comparison shows that: i) the Cost of Transport relative to the soft robot with optimised stiffness is lower than that obtained for its rigid counterpart, especially in running; ii) the forward speed for which running is more efficient than walking is lower for the soft robot than for its rigid counterpart; iii) the soft robot with optimised stiffness can run significantly faster than its rigid counterpart.
