Exploring the Relationship between Human Resource Management Practices and Organizational Commitment: Empirical Evidence from the Banking Sector in China
No full textThe purpose of this paper is to measure the impact of human resource management practices individually and as a system on organizational commitment. Data were collected from 304 respondents from banking sector of China. A questionnaire survey for this purpose was conducted in different cities of China. Correlations and multiple regression statistics analysis were used to explore the relationship between the variables involved in the study. The findings of the study provide support for the variables (selection, training, performance appraisal, promotion, performance based rewards, information sharing, job security and human resource management system) and are confirmed by the results of the previous studies. The findings of the current study support the notion that the HR practices relates to organizational commitment, individually and as a system as well. These findings provide important avenues for the banking sector of China and for the debate regarding convergence of the human resource management practices regionally as well as internationally

Author response: Vocal development in a Waddington landscape
No full textVocal development is the adaptive coordination of the vocal apparatus, muscles, the
nervous system, and social interaction. Here, we use a quantitative framework based on optimal
control theory and Waddington’s landscape metaphor to provide an integrated view of this
process. With a biomechanical model of the marmoset monkey vocal apparatus and behavioral
developmental data, we show that only the combination of the developing vocal tract, vocal
apparatus muscles and nervous system can fully account for the patterns of vocal development.
Together, these elements influence the shape of the monkeys’ vocal developmental landscape,
tilting, rotating or shifting it in different ways. We can thus use this framework to make quantitative
predictions regarding how interfering factors or experimental perturbations can change the
landscape within a species, or to explain comparative differences in vocal development across
species

No full textUsefulness of Clinical Prediction Rules, D-dimer, and Arterial Blood Gas Analysis to Predict Pulmonary Embolism in Cancer Patients
No full textObjectives: Pulmonary embolism (PE) is seven times more common in cancer patients than non-cancer patients. Since the existing clinical prediction rules (CPRs) were validated predominantly in a non-cancer population, we decided to look at the utility of arterial blood gas (ABG) analysis and D-dimer in predicting PE in cancer patients. Methods: Electronic medical records were reviewed between December 2005 and November 2010. A total of 177 computed tomography pulmonary angiograms (CTPAs) were performed. We selected 104 individuals based on completeness of laboratory and clinical data. Patients were divided into two groups, CTPA positive (patients with PE) and CTPA negative (PE excluded). Wells score, Geneva score, and modified Geneva score were calculated for each patient. Primary outcomes of interest were the sensitivities, specificities, positive, and negative predictive values for all three CPRs. Results: Of the total of 104 individuals who had CTPAs, 33 (31.7%) were positive for PE and 71 (68.3%) were negative. There was no difference in basic demographics between the two groups. Laboratory parameters were compared and partial pressure of oxygen was significantly lower in patients with PE (68.1 mmHg vs. 71 mmHg, p = 0.030). Clinical prediction rules showed good sensitivities (88−100%) and negative predictive values (93−100%). An alveolar-arterial (A-a) gradient > 20 had 100% sensitivity and negative predictive values. Conclusions: CPRs and a low A-a gradient were useful in excluding PE in cancer patients. There is a need for prospective trials to validate these results
The time-varying propagation between oil market and stock market- An evidence of Pakistan Stock Exchange, PSX
No full textThe prime objective of this study is to find out the time-varying propagation between the oil market and stock market. For this purpose the crudeoil future contracts in real time was chosen as proxy for an oil market determinant while two indices at Pakistan stock exchange were taken as stock market determinants. In this regard KSE100 index and KMI30 index (the Islamic index) were considered as stock market variables to examine short run or long run relationship amongst the oil market and stock market. The analysis was based on time series data. The weekly closing prices were collected for the period ranging from June, 2009 to August, 2020 with 583 total observations. The study used the Johanson and Juselius (1990) technique to examine the long run cointegration between the variables. The ADF test postulated that all series were at 1(0) nonstationary but it became stationary when taking it at 1st difference. The Johanson cointegration test examined that Pakistani stock indices were cointegrated in the long run with the crudeoil. Once Johanson test founded the long run relationship among the variable, VECM is used to examine the short run dynamics of long run equilibrium relationship. The variance decomposition revealed that fluctuations in the oil prices were strongly endogenous from its own variance in the short run but strongly exogenous in the long run from others independent variable in the model. The impulse response function demonstrated that response of KSE100 and KMI30 both to the shock of crudeoil showed increasing trend in the short run but in long run they have constantly decreasing trend
Does the Specific Matrix of Cultural Values and Ethnic- Religious Diversity Hinder Economic Development in African Region?
No full textAbstract This study empirically probes the role of culture in fostering or hindering economic performance in Africa. Our results show that cultural values appear to some extant have statistically significant and operationally meaningful economic effects. We also test the effect of ethnic and religious diversity which discourage economic growth. Using the OLS method, we appraised the baseline endogenous economic growth model to incorporate cultural variables. Cultural attitudes toward trust and self-determination were found to affect economic development significantly. However, respect was associated with unexpected signs of an inverse relationship with economic growth. Further, the cultural motivational index (CMI) was also negatively associated with growth. This implies that the traditional values of African culture do not lend support to economic growth. While the ethnic and religious fractionalization may not be harmful to development, ethnic and religious polarization affects the development more adversely
