Bacteriological patterns and antibiotic sensitivities in calculus cholecystitis.

BACKGROUND: Calculus cholecystitis with its complications dominates the diseases of the biliary tract. There is an inherent difficulty in identifying patients having infected gall bladders who may have the risk of wound infection or gram negative septicaemia after cholecystectomy. This study was conducted to ascertain the bacteriological patterns and antibiotic sensitivities of bile in calculus cholecystitis patients presenting at a tertiary care hospital and formulate guidelines for prophylactic antibiotic therapy. METHODS: This descriptive study was conducted in Combined Military Hospital, Rawalpindi from 20th Dec 2006 to 19th Sep 2008. A total number of 150 patients presenting at CMH Rawalpindi for elective cholecystectomy were included in the study. Prophylactic antibiotics were given after the induction of anaesthesia, 5 ml of bile was aspirated from their intact gall bladder was subjected to bacteriological examination at Armed Forces Institute of Pathology. A pro forma was designed to record all the information regarding isolated bacteria and their sensitivities to various antibiotics. Data was analyzed using SPSS-11. RESULTS: Growth of bacteria was seen in 57 (38%) cases and no growth was seen in 93 (62%). Most common organism cultured was: Pseudomonas aeruginosa followed by Escherichia coli (E. Coli) and Klebsiella pneumoniae. The most effective antibiotic was Imipenem followed by Piperacillin- Tazobactum combination and Amikacin. CONCLUSIONS: Imipenem, Piperacillin-Tazobactum combination and Amikacin should be used for prophylaxis in cases of cholelithiasis undergoing elective cholecystectomy.

Going green: Impact of green supply chain management practices on sustainability performance.

The rising environmental challenges are capturing the attention of stakeholders of corporations due to increasing competition. The sustainable performance of firms does not merely gauge their economic performance but also their sustainable development. Since the environmental supply chain management of firms has an important part in maneuvering their sustainable performance, the present study focuses on assessing the impact of green supply chain management practices on the sustainable performance of the textile, automobile, and tobacco industries. The data were collected from 384 organizations and analyzed through SPSS and AMOS. The results reveal that the impact of green manufacturing, green purchases, eco-design, and green information system are significant and positive on the sustainable performance of the organizations, whereas the impact of cooperation with customers is insignificant. Similarly, the moderation of institutional pressures between green manufacturing, green purchases, eco-design, and sustainability performance is insignificant, whereas it significantly moderates between cooperation with customers, green information systems, and sustainable performance. The study is significant and novel for considering five different factors of green supply chain management (GSCM): green manufacturing, green purchasing, cooperation with customers, eco-design, and green information systems. Furthermore, adding institutional pressures as a moderator between GSCM and sustainable performance adds to the novelty and uniqueness of the research. The managerial implications have also been discussed.

Firing on all cylinders: Configuring information technology around the constituents of corporate entrepreneurship to outperform in SME sector.

This study has examined how small and medium enterprises (SMEs) may enhance their performance under different settings of information technology (IT) capabilities and corporate entrepreneurship (CE). Established on the dynamic capability view, the researchers have analyzed the connections between IT capabilities and CE, in addition to the performance results of SMEs. The research has explored these novel relationships by utilizing partial least square-structural equation modeling (PLS-SEM) with a data sample of 447 SMEs of the manufacturing sector in Pakistan. The findings present that IT capabilities positively influence the market and financial performance of SMEs through the mediating role of CE dimensions. The study uniquely determines the mediating role of dimensional effects of corporate entrepreneurship between IT capabilities and performance outcomes of firms. Thus, the study would enable the management of SMEs to realize the potential of IT-related CE dimensions and their use to improve firms' performance.

Humor of the Leader: A Source of Creativity of Employees Through Psychological Empowerment or Unethical Behavior Through Perceived Power? The Role of Self-Deprecating Behavior.

Although we use humor in our daily communication, there still needs to cognize its effects on the attitudes and behavior of the employees. Based on benign violation theory (BVT), the study proposes that leader's humor (LH) conveys social information about counter norms. The BVT has been amalgamated with social information processing theory (SIPT) to develop hypotheses assuming the consequences of LH on the attitude and behavior of the employees. This study hypothesizes that even though LH is linked positively with employee creativity via leader-member exchange and psychological empowerment in sequence (blessing path), it may also send information to the employees about the acceptability of norm violation. This perception ultimately leads to power perception and, causes unethical behavior in the series (curse path). Moreover, this study also postulates that leader's self-deprecating humor (LSDH) moderates these indirect effects by enhancing the blessing and reducing the curse, which emerged from LH. Quantitative data of 630 software engineers from software houses based in Pakistan provided support to test the hypotheses. The results demonstrate that LH is a double-edge sword that enhances blessing (creativity) as well as curse (employee unethical behavior), whereas LSDH augments the blessing and throttles back the curse. Theoretical and managerial implications have also been discussed.

Students' Performance in Online Learning Environment: The Role of Task Technology Fit and Actual Usage of System During COVID-19.

The 2019 Pandemic has forced students to take online classes, increasing their stress levels and negatively impacting their academic performance. This issue urges the development of a mechanism to make online learning more effective in this nerve-racking time. Therefore, the present study has integrated the task technology fit (TTF) model and the DeLone and McLean Model of Information Systems Success (DMISM) to address the stated issue. The data were collected from 330 and 326 students of top-ranked public and private universities of Punjab, respectively. The theoretical framework was analyzed with the help of structural equation modeling (SEM) using Analysis of Moment Structures (AMOS). The findings indicate that overall quality positively predicts performance through the mediating role of user satisfaction and TTF. The overall quality also positively elevates performance through the mediating role of user satisfaction and actual usage of the system. Moreover, perceived usefulness proved to be a moderator between overall quality and user satisfaction. Finally, the expected practical and theoretical implications have also been discussed.

The Interplay between Corporate Social Responsibility at Employee Level, Ethical Leadership, Quality of Work Life and Employee Pro-Environmental Behavior: The Case of Healthcare Organizations.

The notion of corporate social responsibility (CSR) has been around for many decades. However, even in 2021, its spectrum is still evolving. Several studies addressed CSR for realizing different organizational outcomes. However, its significance in achieving employee-related consequences is relatively new to the literature. In the same manner, it is not clear from existing literature how ethical leaders can impact their followers' CSR-related behavior, for example, employee pro-environmental behavior (EPB). With this background, the current study aims to explore the relationship of CSR at the employee level (CSR-E) with EPB through the mediating effect of ethical leadership (ELS) in the healthcare sector of a developing economy. This study also proposes a conditional indirect effect of quality of work-life (QWL) in this relationship. The data for the current study were obtained from different hospitals located in a large city through a self-administered questionnaire. The data were examined through the structural equation modeling (SEM) technique. The results validated that CSR-E positively influences EPB, and ELS partially mediates this relationship. Furthermore, the results also confirmed the presence of the conditional indirect effect of QWL in the proposed relationship of the current study. These findings will be helpful for healthcare policymakers to enhance the pro-environmental behavior of employees at the workplace through CSR-E and ELS. These results will also be helpful in reducing the overall environmental footprint of a hospital.
