A Conceptual Review of the Determinants of Employee Innovative Work Behavior

The increasing prevalence of digitalization, competitive markets, quick environmental changes, and the imperative of organizational sustainability have necessitated business organizations to adopt innovative practices. Hence, all organizations must foster a culture of innovative work behavior among their employees to ensure the organization's ongoing survival and advancement. Nonetheless, comprehensive studies that methodically scrutinize the different factors affecting IWB within a unified theoretical model are insufficient. This research is a literature review to find and analyze factors that influence innovative work behavior. The findings of the literature review or existing research indicate that psychological empowerment, employee engagement, self-efficacy, knowledge sharing, perceived organizational support, climate for innovation, HRM practices, and transformational leadership have consistently demonstrated strong associations with employee IWB in various studies. This study additionally proposes a novel conceptual framework that examines the interplay between psychological empowerment, employee engagement, self-efficacy, knowledge sharing, perceived organizational support, climate for innovation, HRM practices and transformational leadership, with a specific focus on their impact on IWB. This framework holds potential for future investigations conducted by other scholars

The TO STUDY ANTIBIOTIC SUSCEPTIBILITY PATTERN OF STAPHYLOCOCCUS AUREUS ISOLATED FROM VARIOUS SKIN SAMPLES

Objective: The study was carried out to check the antibiotic susceptibility profile of Staphylococcus aureus. Methods: In this study for the isolation of strain, skin swabs from different parts of the body were taken aseptically with the set protocol. The sensitivity patterns of S. aureus were explored with different antibiotics for the treatment of S. aureus infections. We have studied the susceptibility pattern of various antibiotics including present all line therapies and other antibiotics using disk-diffusion method. Results: It has been found that bacteria show the highest sensitivity toward third-line antibiotic tetracycline, trimethoprim, and minocycline. The different concentrations of these antibiotics were used to check the minimum inhibitory concentration and found to be effective even at the lower concentration of 0.01 mcg/disc. Furthermore, the minimum inhibitory concentration of each antibiotic has been calculated to find the most effective antibiotic at low concentration. The isolates are found to be highly resistant toward ampicillin, ciprofloxacin, and cefotaxime. Conclusion: The research concluded that the bacteria S. aureus are found to be more sensitive for chloramphenicol, kanamycin, and trimethoprim in first-line antibiotics, second-line antibiotics, and third-line antibiotics, respectively

Brain tumor inhibition in experimental model by restorative immunotherapy with a corpuscular antigen

805-813<span style="font-size:14.0pt;line-height: 115%;font-family:" times="" new="" roman";mso-fareast-font-family:"times="" roman";="" mso-ansi-language:en-in;mso-fareast-language:en-in;mso-bidi-language:hi"="" lang="EN-IN">In view of the advances in our understanding of anti-tumor immune response, it is now tempting to contemplate the development of immunotherapies for malignant brain tumors, for which no effective treatment exists. Immunotherapy, with agents known as biological response modifiers (BRMs) are thus gaining increasing interest as the fourth modality of treatment. A non -specific BRM, sheep erythrocytes (SRBC) when administered (ip, 7% PCV/V, 0.5 ml) in a group of animals at the end of seventh month of ethylnitrosourea administration, resulted in significant increase in the mean survival time (&gt;350 days). Studies conducted for growth kinetics pattern with proliferation index and fluorochrome (HO - 33342) uptake techniques at the tissue culture level exhibited a regulatory inhibition of the cells isolated from tissue excised from the tumor susceptible area of brain of SRBC treated animals. Moreover, histological examination of brain from animals showed immunomodulatory role of SRBC in experimentally induced brain tumor. Further probe into the mechanisms involving immunological investigations at the cellular level in these animals indicated an augmented and potentiated cell mediated immune response (CMI) as evidenced by enhanced spontaneous rosette forming capacity and cytotoxic activity of lymphocytes and neutrophil (PMN) mediated phagocytosis respectively. The observations suggest that SRBC down regulate malignant growth pattern of experimental brain tumors either by an immunologically enhanced killing of tumor cells and/or by directly inhibiting the tumor growth possibly via a stimulated cytokine network. Thus, a corpuscular antigen, can potentiate CMI response in experimentally induced brain tumor animal model, in which response induced in the periphery are able to mediate anti-tumor effects in the brain.</span

Human Face SEGMENTATION AND IDENTIFICATION

This thesis considers segmentation and identification of human faces from grey scale images with clutter. The segmentation developed utilizes the elliptical structure of the human head. It uses the information present in the edge map of the image and through some preprocessing separates the head from the background clutter. An ellipse is then fitted to mark the boundary between the head region and the background. The identification procedure finds feature points in the segmented face through a Gabor wavelet decomposition and performs graph matching. The segmentation and identification algorithms were tested on a database of 48 images of 16 persons with encouraging results. The support of the Advanced Research Projects Agency (ARPA Order No. 8459) and the U.S. Army Topographic Engineering Center under Contract DACA76-92-C-0009 is gratefully acknowledged, as is the help of Sandy German in preparing this paper.

Leadership Style and Quality of Work Life among Nurses in Malaysia during the COVID-19 Pandemic Crisis

The aim of this study is to investigate the association between leadership styles and the quality of work life among nurses in Selangor. The researcher used four independent variables, which are transformational, transactional, autocratic, and democratic leadership styles, while the dependent variable is Quality of Work Life (QWL). This study utilized a correlational quantitative design with 202 nurses. The researcher used a simple random sampling method to distribute the questionnaires. The findings revealed that transformational, transactional, autocratic, and democratic leadership styles are correlated with the QWL, indicating positive, moderate, and significant relationships. While regression analysis shows the most influential leadership style on QWL was the Transactional Leadership style, this study is significant to nurses as there are a need to identify the best leadership style that can assist nurses in the healthcare industry to perform their best and to help human resource managers to identify which leadership style is suitable for the management and the nurses. Apart from that, management can use these findings to aid leaders in improving their leadership skills and moulding competent leaders in a way that improves employees’ quality of life at work. Empirically, this study is relevant to ensure the 2030 Agenda for Sustainable Development Goal (SDG) is fulfilled in SDG 3 and SDG 8
