Quality has taken central stage in contemporary organizations and is one of the key areas of competition. Healthcare organizations, in particular, strive to provide better quality services to their patients in order to gain competitive advantage. Researchers and academicians have yet to agree on how to define and measure quality of service. Attempts have been made to develop standards and measurements to determine the degree of quality of services. However, the literature does not contain a model or standards to measure the quality of health care services. The paper in question presents an inclusive model to measure the quality of service of healthcare organizations. In addition to healthcare services (cure and care) the model encompasses teaching aspect of hospitals as well. This model was developed on the basis of an in-depth and careful study of a large (2400 bedded) public sector teaching hospital spread over a period of two years. Data was collected from 400 patients, 250 employees, 200 general public, and 250 students through questionnaire followed by in-depth interviews. In addition to all this, various processes and interactions among individuals in the hospital were closely observed. Hospital records were studied. Anything that possibly could contribute to the quality of service in hospital was placed under one of the three dimensions of the model. Since the model has been inductively developed through data triangulation, it can safely be used to measure the quality of health care services with a good deal of accuracy.

Artificial neural networks are extensively used to predict the financial time series. This study implements the neural network model for predicting the daily returns of the Pakistan Stock Exchange (PSE). Such an application for PSE is very rare. A multi-layer perception network is used for the model used in this study, while the network is trained using the Error Back Propagation algorithm. The results showed that the predictive power of the network was performed by the return of the previous day rather than the input of the first three days. Therefore, this study showed satisfactory results for PSE. In short, artificial intelligence can be used to give a better picture of stock market operators and can be used as an alternative or additional to predict financial variables.

Mutual funds have become an attractive investment option particularly for small investors to diversify their portfolio. The aim of this study is to explore the determinants of close ended mutual funds return in Pakistan. For this purpose secondary data is used from 2007-2013. Multiple regression analysis is carried out to measure the determinants (fund size, liquidity, expense ratio and fund turnover) of fund return. The findings of the study revealed that expense ratio and fund turnover significantly influences the return of the fund. Moreover, fund size is positively related to fund return whereas expense ratio, fund turnover and liquidity are inversely related to fund return.

The aim of this study is to examine the impact of privatization of state-owned enterprise on financial performance, employees’ satisfaction and customer satisfaction. Pakistan Telecommunication Company Limited (PTCL) was taken as the organization for analysis. Five years pre and post-privatization financial figures were analyzed to compare the return on asset, return on equity, earning per share, net profit margin, and dividend payout. To know customer satisfaction level, the questionnaire was personally administered and 102 questionnaires complete from all respects were included for analysis. A semi-structured interview was conducted with 25 employees to determine the satisfaction level of employees. Findings of the study confirmed adverse financial performance after privatization followed by the high level of employees’ dissatisfaction. However, customer satisfaction level was high after privatization

Customer service orientation is about knowing customers and willingly responding their expectations. Research efforts are underway to identify antecedents of customer service orientation. This concept is essential for service sector organizations. This study has examined the impact of Transactional leadership, Transformational leadership and perceived organizational support as antecedents of customer service orientation in the banking sector. Data from 278 respondents was gathered from bank employees in Islambad, Pakistan. Results have shown a positive and significant impact of all three antecedents on customer service orientation. This study will help banking sector organizations to design policies for enhancing customer service orientation by improving employees performance with effective leadership and supportive work environment.

This study aims to investigate the working capital management practices and its effects on firms’ profitability with moderating role of leverage. The Generalized Method of Moments estimation technique under fixed effect specification is used to analyze the cross-industries sample of 210 nonfinancial firms listed on Pakistan Stock Exchange. The result showed that receivable collection period and payable payment period have positive significant impact on profitability of firms, on the other hand cash cycle has significant negative impact on profitability of firms, and where as the impact of payable payment period is found insignificant on profitability. In case of moderation of leverage with respect to relationship of working capital with profitability the results showed that leverage weakens this relationship significantly. The study suggests that managers in nonfinancial sector should take into consideration the moderating role of leverage with respect to working capital management.

Although the concept of brand loyalty and equity in recent times has evolved one of the dominant phenomena of brand management, yet the picture is incomplete without considering the role of consumer involvement levels. The purpose of this study is to investigate significant antecedents of brand loyalty, and its role in building brand equity, relationships are also measured by conducting comparative analysis of consumer involvement levels. The self-administered survey and regression analysis used to measure relationships of variables. The findings showed significant and positive relationship of perceived quality, brand trust, and customer satisfaction with brand loyalty, and highly significant and positive impact of brand loyalty is found in building brand equity. Significant differences are found between high and low involvement settings. This research will provide exceptional learning opportunities for brand managers and scholars alike, through empirical verifying the relationships of variables, by using two brands of different consumer involvement levels.

The current research study focus on investigating the model of leadership, its effectiveness and emotional intelligence level among the banking sector employees proposed by (Badrui-Harun, Zainol, Amar and Sheri.,2016). In order to get appropriate response data was obtained from banking sector employees located in Islamabad through random sampling technique. Total 600 questionnaires were distributed among the selected head office employees of different banks. After removing missing item constructs finally 390 questionnaires were used for further analysis. In order to validate the model (Barron and Kenny.1986) mediational technique through regression analysis was performed. Results indicate that direct relationship between (Transformational and Transactional Leadership) with effectiveness (Dependent Variable) and Emotional Intelligence (Mediating Variable) was significant. That leads to acceptance of the hypothesis relating direct relationship among these variable. In the next stage mediating variables findings show that emotional intelligence fully mediate the relationship between Transformational leadership style and leader’s effectiveness, while EI partially mediate the relationship between Transactional Leadership and leader’s effectiveness. Result indicate that emotional intelligence act as a good mediator between transformational leadership and leader effectiveness.
目前的研究重点是调查(Badrui-Harun, Zainol, Amar和Sheri.，2016)提出的银行部门员工的领导模式，其有效性和情商水平。为了得到适当的回应，通过随机抽样技术从位于伊斯兰堡的银行部门雇员中获得数据。调查问卷共600份，选取了不同银行的总行员工进行调查。剔除缺失项目结构后，最终使用390份问卷进行进一步分析。为了验证模型(Barron and Kenny.1986)，采用回归分析的中介技术。结果表明，变革型领导和交易型领导与绩效(因变量)和情绪智力(中介变量)之间存在显著的直接关系。这导致人们接受这些变量之间存在直接关系的假设。在下一阶段的中介变量研究中发现，情商在变革型领导风格与领导者效能的关系中起完全中介作用，而情商在交易型领导风格与领导者效能的关系中起部分中介作用。结果表明，情绪智力在变革型领导与领导效能之间起着良好的中介作用。
