    doi: 10.14456/ITJEMAST.2019.227

    Keywords: Dynamic neighborhood models; Variable neighborhoods; Linear models; Parametric identification; Identification criteria; Pseudo-inverse matrix.

    Abstract
    The paper presents the definition of the dynamic input-state neighborhood model, the structure of which is determined by the set of nodes and the neighborhood links between model nodes according to control actions and states. The dynamic neighborhood model functions in discrete time. The states of each node in the next point in time depend on the control actions and the states of adjacent nodes and change under the influence of the state recalculation function. The paper considers a neighborhood model with variable neighborhoods, which is distinguished by dynamic links between the nodes of the system, changing at each discrete point in time of its operation. In this model, the entire set of neighborhood links is divided into intersecting subsets that form layers. For dynamic neighborhood models, the problem of parametric identification is given, the identification criterion is shown. The method is considered and the block diagram of the solution of the parametric identification problem for linear neighborhood models in matrix form is given.

    Keywords: Mutual funds; Ordinary least square (OLS); Time variant effect; Sharpe ratio; Fisher z-transformation; Skewness and kurtosis.

    Abstract
    The first objective of our paper is to identify if the skewness and kurtosis having an impact on the end result in relation to the distribution return pattern of returns in mutual fund industry of Pakistan. The second objective evaluates the persistency in the performance of chosen performance measures against Sharpe measure. In this regard, ordinary least square (OLS) method approach has been applied first and secondly, the fisher z-transformation approach has been used to evaluate the degree of concordance among the alternative performance measures and the Sharpe ratio. The results from (OLS) method verified that the skewness and kurtosis had no impact on the relationship between the alternative measures and Sharpe ratio in evaluation of mutual funds classes. Whereas, from degree of concordance analysis the alternative measures against the non-normal distribution seem more logical choice simply because the deviation is far lower than ones based upon assumption of normal distribution.

    Keywords: Counter-Productive Work Behavior (CWB); Job Performance; WOS; Organizational Cynicism (OC); Perceived Organizational Support (POS); Leader-Member Exchange (LMX).

    Abstract
    Various employees had reported being left out at the workplace which might have reduced in-role performance and adaptive performance or might have enhanced counterproductive work behaviour. Limited research has been conducted on Ostracism. Few recent studies relate to negative and psychological effects of ostracism, however, the effects on job performance and moderating effects of leader-member exchange (LMX) and perceived organizational support (POS) need to be explored studied. Moreover, the mediating role of cynicism has not yet been studied. This study has proposed a research model to explore the relations between workplace ostracism (WOS) and organizational cynicism (OC) and their impact. Managers of service sector need to comprehend ostracism phenomenon and take remedial measures for the betterment of the employees and the organization.

    Keywords: Calcium hydroxide; Polymer-modified; cement system; Polymer-modified mortar (PMM); Mortar strength; Adhesion properties; Toyoura sand.

    Abstract
    Polymer-modified mortars (PMMs) are prepared by using dispersible polymer powders or powdered emulsion (powered cement modifiers) and aqueous polymer dispersion (aqueous cement modifiers) with various polymer-cement (P/C) ratios. Specimens are made with the help of moulds and cured. Different tests like compressive strength, flexural strength, tensile strength, maximum deflection, maximum extreme tensile fibre strain, maximum tensile strain and adhesion in tension or bond strength are performed for the cured specimens. Afterward, powder samples are made from the broken specimens, which are then subjected to X-ray diffraction, differential thermal analysis (DTA) and thermal gravimetric analysis (TGA). From the test results, it is concluded that the formation of calcium hydroxide (Ca(OH)2) is reduced in (PMMs). Whereas, on the other hand, their compressive strength, flexural strength, tensile strength, maximum deflection, maximum extreme tensile fibre strain, maximum tensile strain and adhesion in tension or bond strength have been improved. However, variation in the above- mentioned properties depend upon the P/C ratio and cement modifier used or both. It has been concluded that the reduction of Ca(OH)2 content in PMMs does not cause any detrimental or adverse effect on their strength, elastic and adhesion properties, they are improved.

    Keywords: Foreign Portfolio Investment (FPI); Co-Integration; VECM; Pakistan Stock Exchange (PSX); Stock Market Returns..

    Abstract
    This research study is designed to study the relationship between stock market indicators and net foreign portfolio investment (NFPI). Long term and short term relationships of five stock market indicators namely stock market capitalization, market returns, market turnover, market risk and market indices with NFPI are analysed through co-integration and vector error correction models (VECM). Three co-integrated vectors are found to show long term relationships and three variables are found to have short term relationships. Similarly, past values have impact on the current values. Regression analysis displays the impact of stock market indicators on NFPI. The results demonstrate that all the stock market indicators have positive and significant impact on NFPI except the market risk which has a negative relation with NFPI.

    Abstract
    The association between financial leverage and corporate investment strategy is considered a significant concern in corporate finance; Therefore, we proceed with this line of research to elaborate further the impact of leverage on investment decisions using panel regression and Two-Stage Least Squares (2SLS) regression. Our sample covers all non-financial Pakistani firms listed in Pakistan Stock Exchange (PSX) from the year 2008 to 2017. The results indicate that there is an inverse relationship between leverage and investment in the Pakistani context. However, this inverse association is unique to higher and lower growth firms. We further documented that leverage has a negative and significant impact on the lower growth firms than the higher growth ones. Our results are aligned with the agency theory of corporate leverage, focusing mainly on the theory that financial leverage has a unique and disciplining position in low growth organizations.

    Keywords: Macroeconomic factors; NPL; ARDL; Cointegration test; Commercial Banks; ARDL bound testing approach.

    Abstract
    Given the level of Malaysian economic openness is high, the performance of the financial system especially the banking institutions is ubiquitously exposed to risks of financial stress arising from global financial uncertainty. This headwind, to some greater or lower extent, can be translated into a more challenging prospect of economic growth, price instability, as well as a slower labor market participation faced by the local economy. With greater challenge, it prompts a call towards a continuous assessment on how these uncertainties impact the stability of the banking sector, of which proxied through the performance of non-performing loans (henceforth NPLs). This paper, therefore, aims to examine the macroeconomic influences on NPLs in the case of Malaysian commercial banks. Employing autoregressive distributed lag (ARDL) and bounds testing approach, we explored whether any of these variables namely GDP growth, inflation, and unemployment rate carry informational content about changes of NPLs. Applying this cointegration test onto a dataset of macroeconomic factors and NPLs data of the period spanning from 1998 to 2018 on a quarterly basis, the result suggests that in the long run and short run, GDP growth and unemployment are correlated with the NPLs fluctuations. Inflation, on the other hand, has no correlation. More particularly, GDP growth depicted a negative relationship with NPLs, while the unemployment rate positively influences the NPLs.

    Keywords: English class; Interaction in English; Learner's conversational skill; Communicative activities; English unease

    Abstract
    Like other countries, Pakistan is struggling for an ideal model for English language teaching in their educational institute. The English language is developing as a persuasive mode of interaction. In Pakistan English language is the second language; therefore, verbal English unease is common in the learners. This research has been conducted in the city Lahore, Pakistan and it is mixed method research. Learners' views regarding the usage of the communicating behaviors for the advancement of their verbal English skill were collected through the closed-ended questionnaire i.e. foreign language class unease scale developed by Elaine Horwitz (1987). It was a quasi-experimental pre-test post-test research. A whole group of forty learners was divided equally in one monitor group and two experimental groups. The research aimed to see the effect of the communicative activities on the learners' verbal English confidence level from the learners' perspective. This study investigated on many factors leading to unease among learners whilst they conversed in a foreign language. The results showed that communicative activities enhance confidence and reduce unease while speaking a foreign language. The research also pinpoints that the institutes that do not encourage their learners to interact in English language often have learners who do not have good conversational skills in English. The findings of the research have shown that the learners' confidence level in verbal English was enhanced when they were taught with the communicative activities in every English language class. Thus it is proposed that communicative activities should be incorporated in the English language classes. The research also recommends that the English language teachers should also be trained well in their verbal English skills.

    Keywords: Structural inspection; Structural strengthening; Structural improvement; Reinforced concrete; Reinforced beam; Structure load test; Concrete slab repair; Beam deflection repair; Beam strengthening.

    Abstract
    This study focuses on the strengthening improvement of reinforced concrete (RC) beams and slab using the Social Science Complex Building (SC2), Thammasat University, Rangsit Campus, Thailand, as the case study. The optimal strengthening design for RC beams in the case study building is recommended. The main focused issue is to reduce the deflections of the beams. There are three strengthening improvement methods that are compared each other. Once completing the design, this study finds that the first, the second, and the third methods have the maximum deflection at 3.57 cm, 3.35 cm, 3.51 cm, respectively. The second method offers the smallest deflection; however, the third method requires the smallest repair amount of strengthening reinforcing steels. When compare to ACI standard, it is clear that the maximum deflections all three methods are within the acceptable standard. Therefore, the third method is considered the most optimal design method.

    Keywords: Sporting Events; Cricket; Mob Psychology; Pakistan Stock Exchange; Stock market prices; Mood Swing; Ordinary Least Squares (OLS); Macroeconomic variable; Event Study.

    Abstract
    This study investigates the impact of international cricket matches on the stock market via sudden changes in social mood associated with the sporting event. This study also considers three important macroeconomic variables to explain changes in the stock market prices. The evidence shows that cricket matches have a short-term adverse effect on the Pakistani stock market. The significant impact of the matches played in financial cities implies that the moods of local investors are induced by sporting events that affect the stock market. The negative effects of game losses are stronger than the game wins, which confirms the existence of asymmetrical biases. The matches against India particularly generates a downward movement in the market returns. Furthermore, there is no evidence of match-fixing and stock market returns.

    Abstract
    The article discusses the issues of increasing the efficiency of day hospital staff through various tools, analyzes new approaches to increase labor productivity in a medical organization. Currently, the role of human capital in the effective functioning of the organization is given much attention. Many companies understand that the success of an organization depends on the people who work in it. The activities of the medical organization can be presented through the process. This approach to management is called the process approach. Currently, companies tend to have developed vertical communications, there is a boss who controls the activities of his subordinates and controls the process, and horizontal communications are poorly expressed. The process approach in human capital implies the development of horizontal links and close work between various functional links that help each other in achieving the overall goals of the organization [5]. In this case, the employee is responsible not only for his functional activities but also for his contribution to the overall business process and the achievement of goals. Thanks to the development of human capital, there is an increase in the efficiency of the entire medical organization. It is important that doctors do their job with maximum efficiency, and patients receive high-quality medical care [2]. The article was held timekeeping activities of each doctor, as well as recommendations on the placement of specialists in a medical organization. All these actions are taking place in the framework of the Lean Polyclinic project of the Russian Federation Ministry of Health.

    Abstract
    The effects of root-feeding stimulators Crezacin, Ribav-Extra, Zircon and Epin-Extra on the growth of seedlings of Khingan fir (Abies nephrolepis (Trautv.) Maxim.) as growing planting material are studied. There was a higher growth activity in seedlings fed with Ribav-Extra growth stimulant at solution concentrations of 1ml/5l and 1ml/10l and Zircon at a concentration of 1ml/10l. Root feeding of seedlings with these stimulants activates their growth in height and biomass, the development of side shoots and the formation of the crown of plants. Three-year-old seedlings can be used for transplanting into the school nursery department, for further cultivation of seedlings and their use in landscape construction. Four-year-old seedlings grown with root-feeding with these stimulants in terms of growth meet the requirements of the current OST 56-98-93 and exceed it in height by 12.3-40.4%, in diameter of the root neck by 6.7-43.3 %.
