The Utilisation of Facebook for Knowledge Sharing in Selected Local Government Councils in Delta State, Nigeria

Aim/Purpose/ Background Facebook has made it possible for organisation to embrace social and network centric knowledge processes by creating opportunities to connect, interact, and collaborate with stakeholders. We have witnessed a significant increase in the popularity and use of this tool in many organisations, especially in the private sector. But the utilisation of Facebook in public organisations is at its infancy, with many also believing that the use of Facebook is not a common practice in many public organisations in Nigeria. In spite of this fact, our discernment on the implications of Facebook usage in public organisations in Nigeria, especially organisations at the local level, seem to be remarkably limited. This paper specifically sought to ascertain if Facebook usage influenced inward and outward knowledge sharing in the selected local government councils in Delta State, Nigeria Methodology The qualitative method was adopted. The study used interview as the primary means of data gathering. The study purposively sampled thirtysix employees as interviewees, twenty from Oshimili South and sixteen from Oshimili North local government councils respectively. The thematic content analysis method was used to analyse interview transcripts. Contribution This research made distinct contributions to the available literature in social knowledge management, specifically bringing to the fore the intricacies surrounding the use of Facebook for knowledge sharing purposes in the public sector. Utilisation of Facebook for Knowledge Sharing 270 Findings The local government councils were yet to appreciate and utilise the interactive and collaborative nature of Facebook in improving stakeholders’ engagement, feedback, and cooperation. Facebook was used for outward knowledge sharing but not for inward knowledge sharing. Recommendations Local government councils should encourage interaction via Facebook, show willingness to capture knowledge from identifiable sources, and effectively manage critical knowledge assets in order to build trust, cooperation, and confidence in the system. To gain strategic benefits from the use of Facebook for synchronous communication of knowledge, local government councils should ensure that the use of such technology is aligned with strategic plans and that directional change is in line with the new knowledge economy, where interaction and collaboration through technology are seen as strategic imperatives for continued success and sustainability. In addition, local government councils need to train stakeholders on effective use of Facebook for knowledge sharing, with special emphasis on how, why, who, when, and where to use such tool for knowledge sharing activities.
Effects of Work Life Balance on Employee Loyalty in Private Commercial Banks of Bangladesh

Maintaining employees’ personal life and work life- which is referred as Work Life Balance- is a recent concept of contemporary Human Resource Management. Banking sector provides one of the busiest working environments in Bangladesh. To achieve its’ business objectives banking sector needs to develop the professional lives of the employees along with their family lives. The study examines employee loyalty’s relationship with work life balance opportunities in private commercial banking sector of Bangladesh.The specific objectives of the research are- to examine to what extend the private commercial banks are giving opportunities to their employees to have proper work life balance, to explore the perceptions of the employees to current work schedule and the factors which are dependent on their loyalty to the organization,. The research adopts a research design where the population size is thirty nine (39) and the sample size is ten (10) private commercial banks. At least hundred (100) structured questionnaires are being filled completely by the employees.Various factors are identified that are directly related to Work Life Balance and employee loyalty such as working hours, leave policies, holidays/ picnics, health programs, work pressure, work distribution, job satisfaction, etc. The findings are based on the employees’ present situation of work life balance in connection with employee loyalty. Recommendations are given on the basis of the areas which need to be focused more and on the basis of the top managements’ responsibilities to make their employees loyal through providing work life balance.If the implementation of the suggested recommendations can be ensured, the objectives of the study will be achieved. Moreover, the study can also help the managers of various organizations to understand how Work Life balance policies can influence proper job satisfaction of employees.

Language Documentation in Diaspora Communities

Due to environmental, economic, and social factors, cities are increasingly absorbing speakers of endangered languages. In this chapter, the authors examine some of the ways that organizations can work with communities in an urban setting to further language documentation, conservation, and revitalization. They base their discussion on their experience at the Endangered Language Alliance, a non-profit organization based in New York City that facilitates collaboration between linguists, students, speakers of endangered languages, and other relevant parties. While ex-situ language documentation has not been given much attention in the literature, they argue that it has its own unique advantages and that diaspora communities need to be taken seriously, both to fully understand language endangerment and to better counteract it.

Covering the Dead in Later Prehistoric Britain: Elusive Objects and Powerful Technologies of Funerary Performance

This paper examines the containment and covering of people and objects in burials throughout later prehistory in Britain. Recent analyses of grave assemblages with exceptionally well-preserved organic remains have revealed some of the particular roles played by covers in funerary contexts. Beyond these spectacular examples, however, the objects involved in covering and containing have largely been overlooked. Many of the ‘motley crew’ of pots and stones used to wrap, cover, and contain bodies (and objects) were discarded or destroyed by antiquarian investigators in their quest for more immediately dazzling items. Organic containers and covers – bags, coffins, shrouds, blankets – are rarely preserved. Our study brings together the diverse and often elusive objects that played a part in covering and containing prehistoric burials, including items that directly enclosed bodies and objects, and those that potentially pinned together (now mostly absent) organic wraps. Overall, we contend, wrapping, covering, and containing were significantly more prevalent in prehistoric funerary practices than has previously been recognised.
Clearing homicides

This article is based on work supported by the Laura and John Arnold Foundation (LJAF). We thank them for the support and note that LJAF is not responsible for any of the content or conclusions herein. Research Summary: Since the RAND Corporation studies on investigations were published, there has been a widely held belief among scholars that police agencies and investigative effort matter little to solving crimes. A few researchers have recently challenged this belief, however, producing results that show that investigative effort does play a role in clearing crimes. In this study, we replicate the methodological approach of the RAND studies and use multiagency, multimethod, detailed case files, as well as organizational analysis, to examine the association among investigative effort, case features, organizational factors, and the clearance of homicide cases. The results show that variation between the homicide clearances in agencies can be explained by case attributes, investigative practices, and organizational differences. Future research should be aimed at building on these results using a similar design with a larger number of agencies.
Pricing companies: Ethno-accounting of private equity activity

How do private equity firms decide on a fair price for a business? Drawing on 76 semi-structured interviews, this article contributes to the sociology of finance and valuation studies by showing that pricing companies is not just a valuation operation but also a capital-repartition issue. In so doing, it shows how concrete, local pricing methods contribute to the financialisation of the economy through the creation of a new capital accumulation centre. The article’s ethno-accounting approach describes three pricing steps: first, the capital access rules applicable to the private equity firm members (the price rationale); second, the expectations about the capital that can be transferred from the business to the private equity firm (the theoretical price level); and third, the transaction participant coordination mechanisms (culminating in the actual price). This description of the practices and concepts inherent in business valuation sidesteps the traditional divide between price formation in constructivist concepts of value as well as price discovery in substantivist concepts of value. Instead, value is defined as the expectation of a transfer of capital from the productive sphere to the private equity firm.

CEO-CFO Educational Ties and Mergers and Acquisitions

This paper analyzes the social connections between a firm’s chief executive officer (CEO) and its chief financial officer (CFO). We focus on French educational networks and examine the corporate governance and performance of firms whose CEO and CFO attended the same elite college (Grande ecole). Given the strong involvement of CEOs and CFOs in the takeover process, we investigate acquisition policies and observe that strong social ties within the top management team are associated with higher acquisitiveness and lower returns for bidder shareholders. These results are consistent with excessive managerial homogeneity reducing CEO monitoring and reinforcing decisional biases such as overconfidence. We find that CEOs are more likely to choose socially connected CFOs when CEOs are more powerful and are employed at firms with lower board monitoring. We also show that CEOs are less likely to be fired when the firms’ CFOs are drawn from the same network. These results suggest that social connections within executive committees come at the cost of CEO entrenchment and corporate governance failures.
Analyzing the I/O Performance of Post-Hoc Visualization of Huge Simulation Datasets on the K Computer

As computational science simulations produce ever increasing volumes of data, executing part or even the entire visualization pipeline in the supercomputer side becomes more a requirement than an option. Given the uniqueness of the high performance K computer architecture, the HIVE visualization framework was developed, focusing on meeting visualization and data analysis demands of scientists and engineers. In this paper, we present an analysis on the input/output (I/O) performance of post-hoc visualization. The contribution of this research work is characterized by an analysis of a set of empirical study cases considering huge simulation datasets using HIVE on the K computer. Results from the experimental effort, using a dataset produced by a real-world global climate simulation, provide a differentiated knowledge on the impact of dataset partitioning parameters in the I/O performance of large-scale visualization systems, and highlight challenges and opportunities for performance optimizations.
Using Self-Organizing Map and Clustering to Investigate Problem-Solving Patterns in the Massive Open Online Course: An Exploratory Study

This study investigated whether clustering can identify different groups of students enrolled in a massive open online course (MOOC). This study applied self-organizing map and hierarchical clustering algorithms to the log files of a physics MOOC capturing how students solved weekly homework and quiz problems to identify clusters of students showing similar problem-solving patterns. The usefulness of the identified clusters was verified by examining various characteristics of students such as number of problems students attempted to solve, weekly and daily problem completion percentages, and whether they earned a course certificate. The findings of this study suggest that the clustering technique utilizing self-organizing map and hierarchical clustering algorithms in tandem can be a useful exploratory data analysis tool that can help MOOC instructors identify similar students based on a large number of variables and examine their characteristics from multiple perspectives.
Affordances and limitations of learning analytics for computer-assisted language learning: a case study of the VITAL project

ABSTRACT Learning analytics (LA) has emerged as a field that offers promising new ways to prevent drop-out and aid retention. However, other research suggests that large datasets of learner activity can be used to understand online learning behaviour and improve pedagogy. While the use of LA in language learning has received little attention to date, available research suggests that LA could provide valuable insights into task design for instructors and materials designers, as well as help students with effective learning strategies and personalised learning pathways. This paper first discusses previous CALL research based on learner tracking and specific affordances of LA for CALL, as well as its inherent limitations and challenges. The second part of the paper analyses data arising from the VITAL project that implemented LA in different blended or distance learning settings. Statistical and process-mining techniques were applied to data from 285 undergraduate students on a Business French course. Results suggested that most students planned their self-study sessions in accordance with the flipped classroom design. Other metrics measuring active online engagement indicated significant differences between successful and non-successful students’ learner patterns. The research implied that valuable insights can be acquired through LA and the use of visualisation and process-mining tools.
A Critical Analysis of the Vocabulary in L2 Spanish Textbooks

This study researches the treatment given to L2 vocabulary in Spanish language textbooks. To that end, 12 textbooks (together with the teacher�s editions) at three proficiency levels were analyzed. The results suggest that the vocabulary to be taught lacks consistency as the selection and grading criteria are not explicitly stated in most of the teacher�s guides. The place of publication and the proficiency level of the textbooks influence the introduction of new words. Vocabulary teaching tends to be rather traditional since its practice is mostly comprised of closed and open exercises and vocabulary learning strategies are rarely present. Finally, the results of research into L2 vocabulary learning have not been taken into consideration. This can be seen in the overuse of semantic sets and the insufficient recycling found in the teaching units.
Stability and control of a compass gait model walking with series-elastic ankle actuation

STABILITY AND CONTROL OF A COMPASS GAIT MODEL WALKING WITH SERIES-ELASTIC ANKLE ACTUATION Deniz Kerimoğlu Ph.D. in Electrical and Electronics Engineering Advisor: Ömer Morgül Co-Advisor: Uluç Saranlı November 2017 Passive dynamic walking models are capable of capturing basic properties of walking behaviors and can generate stable human-like walking without any actuation on downhill surfaces. The passive compass gait model is among the simplest of such models, consisting of a planar point mass and two stick legs. A number of different actuation methods have been proposed both for this model and its more complex extensions to eliminate the need for a downhill sloped ground, balancing collision losses using gravitational potential energy. In this thesis, we introduce and investigate an extended compass gait model with series-elastic actuation at the ankle towards a similar goal, realizing stable walking on various terrains such as level ground, inclined surfaces and rough terrains. Our model seeks to capture the basic structure of how humans utilize toe push-off prior to leg liftoff, and is intended to eventually be used for controlling the ankle joint in a lower-body robotic orthosis. We derive hybrid equations of motion for this model and obtain limit cycle walking on level and inclined grounds. We then numerically identify fixed points of this system and and show numerically through Poincaré analysis that it can achieve asymptotically stable walking on level and inclined ground for certain choices of system parameters. The dependence of limit cycles and their stability on system parameters such as spring precompression and stiffness for level ground walking is identified by studying the bifurcation regimes of period doubling of this model, leading to chaotic walking patterns. We show that feedback control on the initial extension of the series ankle spring can be used to improve and extend system stability on level ground walking. Then, we investigate and identify the period doubling bifurcation regions of our model for spring precompression and ground slope parameter leading to various maps that we utilize for rough terrain
Debt Policy: Affecting Factors and Their Impact on Company Values

One of the main sources of funding for operational activities and company expansion is derived from debt. The company's debt policy is a policy made by the management as the manager of the company. The debt policy will have an impact on the company value as reflected in the market price of the company's shares. This study aims to prove the factors that influence the company's debt policy and the impact of the debt policy on the company value. The factors that influence debt policy as an independent variable of this study are: managerial ownership, institutional ownership, company growth, free cash flow and company size. The company's debt policy is proxied by the Debt to Equity (DER) ratio and the company value is proxied by the Price to Book Value (PBV) ratio. The research sample is a manufacturing company selected based on criteria, so as to obtain as many as 91 companies registered in 2014-2016. Using multiple regression analysis on alpha = 5%, the results show that managerial ownership and Free cash flow affect the company's debt policy, while other variables have no effect on it. Debt policy did not affect the value of the company. Keywords: Debt policy, company value, managerial ownership, free cash flow, company size DOI : 10.7176/RJFA/10-14-14 Publication date :July 31 st 2019
Does Diversification Strategy Reduce The Level of Financial Distress? (Evidence from Indonesia)

The objective of this study is to investigate the effect of diversification strategy towards the level of financial distress. Altman Z-score is used to measure the level of financial distress and Herfindahl index is used to measure diversification in this research. This study used 101 non-financial companies listed in Indonesian Stock Exchange during 2014-2016 (303 firm years) as samples. For testing the hypotheses, Mann Whitney test and panel data regression with random effect model was used. The results showed that there are Z score differences between high and low diversified firms; and diversification has a negative effect towards the level of financial distress. The control variables testing showed that liquidity, profitability, and firm size negatively influence the level of financial distress, while leverage has a positive effect towards the level of financial distress. Besides, the type of diversification has no effect toward financial distress.
Informal Sector and Mobile Financial Services in Developing Countries: Does Financial Innovation Matter?

This paper investigates the impact of mobile financial services - MFS (mobile money, and mobile credit and savings) on the informal sector. Using both parametric and non-parametric methods on panel data from 101 emerging and developing countries over the period 2000-15, we find that MFS negatively affect the size of the informal sector. According to estimates derived from propensity score matching, MFS adoption decreases the informal sector size in a range of 2.4 – 4.3 percentage points of GDP. These formalization effects may stem from different possible transmission channels: improvement in credit access, increase in the productivity/profitability of informal firms attenuating subsistence constraints typical of entrepreneurship in the informal sector, as well as possible induced growth of firms already in the formal sector. The robustness of these results is supported by the use of an alternative estimation approach (instrumental variables). These findings lay the groundwork for the scarce literature on the macroeconomic impact of mobile financial services, a major dimension of the growing drive towards economic digitalization transiting through industry-level MW.
