Classification of Javanese Eagle Tweet Based on Improved Mel-Frequency Cepstral Coefficients and Deep Convolutional Neural Network
Get PDFThe Javanese Eagle is a rare and protected animal in Indonesia, threatened with extinction due to its limited population. Conservation efforts in zoos and nature reserves are essential to prevent their extinction. One critical aspect of conserving the Javanese Eagle is understanding their communication through tweets, which can provide insights into their needs and behaviours. This study addresses the problem of effectively classifying the Javanese Eagle's vocalizations to aid in their conservation. The primary technique involves the use of Improved Mel Frequency Cepstral Coefficients (IMFCC) and Deep Convolutional Neural Networks (DCNN), combined to create a robust classification system. Data were collected from zoos and nature reserves in Indonesia, used to train and test the models, and then validated by experts. Experts validate after the best model is obtained and use new data to test its validity. The classification system aimed to distinguish between tweets indicating lack of food or drink, normal tweets, and those related to finding a partner. The study compared various CNN architectures, including AlexNet and VGGNet, and different combinations of training, validation, and test data. The best-performing model, VGGNet, was trained with a dataset split into 80% training, 10% validation, and 10% testing. During training, the VGGNet model achieved a peak accuracy of 100%, and during testing, it attained an accuracy of 99%. The Receiver Operating Characteristic (ROC) Curve analysis showed that the 'Normal' category had an area under the curve of 0.996, the 'Looking for Partner' category had an area under the curve of 1.000, and the 'Looking for Food' category had an area under the curve of 0.996. These results demonstrate the effectiveness of the proposed classification system in accurately identifying the Javanese Eagle's primary needs. The significance of this study lies in its potential to enhance conservation efforts by providing a reliable tool for monitoring the Javanese Eagle's well-being. By accurately classifying their vocalizations, conservation site managers can better understand and address the eagles' needs, improving their chances of survival and preventing extinction. This research also contributes to the broader field of bioacoustics and wildlife conservation, offering a methodology that can be adapted for other endangered species
Impact of Corporate Social Responsibility, Morality and Servant Leadership on Employee Performance
Get PDFThis study investigates the impact of employee-centric embedded corporate social responsibility (CSR) and servant leadership on the contextual performance of staff nurses in the public sector of Pakistan. It also examines the roles of moral identity as a moderating variable and affective organisational commitment as a mediating variable. Contextual performance, encompassing the non-technical aspects of a nurse's job, is crucial for the overall effectiveness and efficiency of healthcare delivery. The study explores how these factors influence the contextual performance of staff nurses in Pakistan's public health hospitals. The philosophy of this study was positivism due to its quantitative nature. The researcher identified variables and developed eight hypotheses using Social Exchange Theory (SET). A research strategy was designed to collect data on observed reality, employing purposive sampling to gather data from 350 staff nurses in public sector hospitals in Rawalpindi/Islamabad, Pakistan. The questionnaire used for data collection was adapted from previous related research. A pilot study was conducted to assess the reliability and validity of the questionnaire. Cronbach's Alpha was used to evaluate these metrics, and the results showed that all values were above the acceptable threshold 0.7. Partial Least Squares Structural Equation Modeling (PLS-SEM) using Smart-PLS software was employed to test and confirm the causal relationships between the proposed hypotheses, with the goal of creating law-like generalizations for future testing. The structural model in PLS-SEM evaluated theoretical relationships and hypotheses concerning both direct and indirect effects among variables and estimated parameters for these relationships (paths). It also analysed complex relationships, including mediation and moderation, and assessed the overall model fit. The findings reveal a significant positive relationship between employee centric embedded CSR and contextual performance of nurses, as well as between servant leadership and nurses' contextual performance. Furthermore, affective organisational commitment was found to partially mediates the relationship between both employee-centric embedded CSR and contextual performance, and servant leadership and contextual performance. However, the study did not find a significant moderating effect of moral identity on the relationship between employee-centric embedded CSR and affective organisational commitment. This suggests that the intrinsic moral values of the nurses do not significantly alter the impact of CSR on their commitment to the organisation. These results provide valuable insights for healthcare administrators and policymakers in Pakistan, highlighting the importance of fostering a supportive leadership style and integrating CSR initiatives focused on employees. Such strategies can enhance affective organisational commitment and, consequently, improve the contextual performance of nursing staff in public healthcare settings. The study contributes to the existing literature by clarifying the interplay between CSR, leadership, organisational commitment, and performance within the context of the Pakistani public healthcare sector
Mediating Effect of Workplace Stress on the Relationship between Perceived Organizational Support and Organizational Commitment among Malaysian Manufacturing Employees
Get PDFThe purpose of the current research was to analyze organizational commitment and to predict the factors that influenced organizational commitment, with workplace stress serving as the mediator. In addition, this research introduced a novel conceptual framework to enhance the understanding of organizational commitment. Most previous studies on organizational commitment, the dependent variable, focused on establishing the direct relationship between the independent variables (predictors) and the dependent variable. However, there was insufficient research to examine the "indirect" relationship between the predictors and the dependent variable. Therefore, this research sought to address this gap by using workplace stress as a mediator to determine whether an indirect relationship existed, which enhanced the understanding of the connection between the predictors and the dependent variables. The theoretical framework of this research was the Job Demands-Resources (JD-R) Theory. Furthermore, the current researcher utilized various elements to anticipate both workplace stress and organizational commitment, including job characteristics, perceived organizational support, and work engagement. The current research adopted both Statistical Package for the Social Sciences (SPSS) and partial least squares structural equation modelling (PLS SEM) as the research method for data analysis. The expected outcome of the study was to determine whether the hypotheses tested were accepted or rejected. The significance of the findings in the study contributed to the literature on factors that could enhance organizational commitment. The results showed a significant relationship between perceived organizational support, workplace stress, and organizational commitment. However, the tested relationships between job characteristics, work engagement, and organizational commitment were found to be not significant. The findings indicated that workplace stress played a strong mediating role between job characteristics, perceived organizational support, work engagement, and organizational commitment

The Efficacy of Emotional Freedom Technique in Reducing Workplace Stress among Healthcare Professionals: A Quasi-Experimental Study
Get PDFThis study explored the relationship between Emotional Freedom Technique (EFT) and workplace stress (WPS) among healthcare professionals. Using a quasi-experimental design, 46 participants (23 males and 23 females) were selected via convenience sampling from twin cities, Rawalpindi and Islamabad. The findings revealed a negative correlation between EFT and WPS, suggesting that individuals experiencing higher levels of stress are more likely to engage in EFT sessions. Paired sample t-tests and ANOVA analyses further demonstrated significant reductions in workplace stress after EFT interventions, with p-values < 0.001 and moderate to large effect sizes (Cohen's d = 0.359 to 0.843). Across subgroups with different initial stress levels, a consistent decline in mean WPS scores was observed (from M = 26.58 to M = 21.17), reinforcing the effectiveness of EFT in reducing workplace stress across diverse healthcare professionals. The study highlights EFT as a promising tool for managing stress in healthcare settings and its potential for general application in reducing stress among professionals from varying backgrounds
Collective Leadership and Its Effectiveness on Malaysian Secondary School Culture
Get PDFThis study examined the effectiveness of collective leadership on school culture in secondary schools of the Federal Territory of Kuala Lumpur. With the constant expanding role of teachers in schools, it is a worthy effort to propagate collective leadership that encourages collaborative efforts that is key to increased efficacy and better performance. In addition, studying this leadership form in metropolitan schools such as those in Kuala Lumpur, Malaysia which are in high-accountability conditions, is a worthy effort which can, in turn inform policy and practice that is essential in the establishment of collective leadership practices. Redesigning leadership roles through collective leadership allows teachers the space to feel empowered and supported which is what is needed in this highly demanding, technologically fast-paced era. To that effect, the purpose of this phenomenological study is to confirm the effectuality of collective leadership practices for a sustained positive school culture and to encourage sanguine teacher behaviours in proliferated capacities. The theoretical underpinnings of this study were established from Friedrich et. al.’s (2014) Collectivistic Leadership Theory and Bolman and Deal’s (2003) Culture Theory. And through all these, the qualitative nature of this study revealed perceptions of six teachers through interviews and observations in order to discover emerging patterns that conformed to the research questions. The findings of this research revealed five domains which are recognition and acknowledgement, collaboration and teamwork, decision-making and responsibility, empowerment and shared goals and trust. These domains result in, teachers being open to accepting collective leadership as part of their school culture as distributing responsibilities based on teachers’ abilities and strengths could contribute to a more positive work environment. Hence the proposition of ‘Teach with CLass’ framework – the novelty of this research, which encourages everyone in the school to work together as a team, championing every individual’s expertise that enables the best possible outcome in a given situation. The implication here is that when teachers feel appreciated for expertise and contribution, the positive impact on their motivation reflects on their job satisfaction and commitment, creative a conducive environment for all stakeholders to thrive
Analyzing Challenges and Opportunities in Entrepreneurship Development: A Study of University Students in Rawalpindi and Islamabad.
Get PDFThis study examines the influence of financial, technical, and cultural barriers on entrepreneurial growth in Pakistan, focusing specifically on college students in Rawalpindi and Islamabad. The research addresses a critical issue: while Pakistan’s economic environment and various government initiatives offer substantial opportunities for business development, excessive government intervention is identified as a major impediment to entrepreneurial innovation and risk-taking. To investigate this, primary data was collected using a structured questionnaire administered to college students. The study employs correlation analysis to explore the relationship between these barriers and the capacity for business growth, as well as to assess the interactions among the different types of impediments. Financial barriers include limited access to funding and financial resources; technical barriers encompass a lack of technical skills and infrastructure; and cultural barriers involve societal attitudes and norms that may hinder entrepreneurial activities.The findings reveal that while government initiatives are well-intentioned, their excessive interference can undermine the entrepreneurial spirit by creating regulatory and bureaucratic hurdles. This research provides critical insights into how these barriers impact the entrepreneurial ecosystem and highlights the need for a balanced approach to government intervention. By offering a detailed analysis of these factors, the study aims to assist scholars and policymakers in developing more effective strategies to enhance Pakistan’s entrepreneurial environment, thereby fostering sustainable business growth and innovation
