A study on Organizational Commitment in relation to Job Involvement in the Information Technology Industry
The research is entitled A Study on Organizational Commitment in relation to Job Involvement in the Information Technology Industry. Both Job Involvement and Organizational Commitment are areas of much interest to academicians, researchers, HR practitioners and the industry in its entirety. The last few decades has seen an increased interest in the study of both Organizational Commitment and Job Involvement by academicians and practitioners in a variety of work settings in the hope that it improves job performance and organizational effectiveness, and reduces tardiness, absenteeism and turnover. Organizations are realizing that it is critical to not just attract the right kind of talent but also ensure the retention of their key talent by addressing the problem of retention. Hence the increased focus on areas such as Job Satisfaction, Job Involvement, Organizational Commitment, Human Resource Development, Psychological Contract, Organizational Citizenship Behaviour or OCB, Organizational Development or OD initiatives, Retention strategies, Employee Engagement, etc. Each of these HR activities play a key role in achieving an organization??s strategy, goals, vision and mission. Both Job Involvement and Organizational Commitment have been studied because they are believed to affect and impact organizational performance and effectiveness in addition to clearly predicting other important variables such as absenteeism, turnover, organizational citizenship behaviour, etc. Several studies have indicated organizational commitment to be a better predictor of turnover than job satisfaction. This study, however, is intended to examine the impact of Job Involvement on Organizational Commitment specifically in the IT industry, and also understand the influence of several personal, situational, and organizational characteristics pertaining to Job Involvement on Commitment. The sample considered was 250 IT workers across various levels (right from industry freshers with no work experience whatsoever to Senior Managers with 12 to 15 years of IT experience) and functions in various IT organizations in Bangalore, India. It involved all employees working in IT organizations, including employees in functions such as HR & Training, Administration, Quality, Marketing/Sales and Finance in these organizations. The tools used for the study were (a) Organizational Commitment Questionnaire or OCQ developed by Meyer, Allen and Smith (1993); the internal reliability coefficient (Cronbach??s alpha) was found to be 0.95; and (b) the Lodahl and Kejner Job Involvement Scale (1965); Cronbach??s alpha for the 20-item Job Involvement scale was 0.79. Some of the key findings of this study were: 1. There is a significant relation between Job Involvement and Organizational Commitment of employees in the Indian IT industry 2. There is a significant influence of Job Involvement on Organizational Commitment of employees in the IT industry 3. There is a significant influence of Job Involvement on Affective Commitment of employees in the IT Industry. 4. There is a significant influence of Job Involvement on Normative Commitment of employees in the IT industry. 5. There is a significant influence of Job Involvement on Continuance Commitment of employees in the Indian IT industry 6. There is a significant difference between Organizational Commitment across demographics in the Indian IT industry. The researcher has also discussed the limitations and future research areas on the variables of this study. -
Women empowerment through community-based organisations in rural Karnataka
Women empowerment is an active multidimensional process to enable women to realize their identity and power in all spheres of life. Self Help Groups (SHGs) have played a significant role in women's empowerment. Through the SHGs, the dreams and desires of women came into reality. The current study examines women's empowerment through community-based organisations in rural Karnataka (Hoskote, Jamkhandi and Kolar). The chapter aims to determine the impact of SHGs on rural women's lives and whether it contributes to women's empowerment. The chapter follows a mixed-method research design. Thirty well-performing SHGs from three Centre for Social Action (CSA) project sites in rural Karnataka, namely Hoskote, Jamkhandi and Kolar, were considered for this chapter. A simple random sampling technique was used. Ten members from each SHG were selected, and three hundred SHG women samples were recruited. Responses from the samples were collected using pre-designed questionnaires. The results state that there is a well-evident improvement in women's economic, social, familial and political status after joining the SHG. The chapter concludes that SHG has caused significant change and development in women's socio-economic, familial and political life in rural Karnataka. 2024 Nova Science Publishers, Inc. -
Adsorptive removal of Cr (VI) using mesoporous iron-aluminum oxyhydroxide-polyvinyl alcohol self-supporting film: Kinetics, optimization studies and mechanism
Over the past decades, the disposal of heavy metals like Cr(VI) from industries had an adverse effect on the environment, thus making it a topic of particular interest. In this context, mesoporous Aluminum oxyhydroxide-polyvinyl alcohol self-supporting films were synthesized, and different transition metals (V, Fe, Co, Ni and Cu) were incorporated by an eco-friendly route, and their adsorptive capacity towards Cr (VI) was studied. The composite mesoporous film with iron, aluminum oxyhydroxide and PVA was more efficient adsorbent than other transition metal incorporated aluminum oxyhydroxide films. The surface and chemical properties of the film were confirmed by pXRD, FTIR, Raman Spectra, BET-Surface area, BJH, SEM and Optical Profilometry. Furthermore, the effect of different parameters that impact the adsorption capacity towards Cr (VI) is discussed, including adsorbent load, contact time, solution pH, temperature, and initial concentration. A detailed investigation of the film before and after the adsorption of Cr (VI) using different characterization techniques is investigated in detail. The kinetic studies and adsorption isotherms are studied, and a suitable mechanism has been proposed for Cr (VI) removal. The synthesized films possess potential advantages like cost-effectiveness, eco-friendly nature, reusability, and higher removal efficiency towards the removal of Cr (VI) from an aqueous solution. 2023 Elsevier Ltd -
Architecture of FTO/n-CdS/p-SnSe1-xOx/Au Heterojunction Thin Film Diodes by Thermal Evaporation
In this report, FTO/n-CdS/p-SnSe1-xOx/Au heterojunction diodes were fabricated using a homemade precursor followed by dry milling with a facile thermal evaporation method under oxygen atmosphere (10? 2mbar) for the first time. The chemical purity (45.35:45.07:9.58 at.%) and microstructure of the deposited films and device were characterized by energy dispersive x-ray analysis, x-ray photoelectron spectroscopy, and scanning electron microscopy. The crystallographic parameters, a = 11.512 b = 4.163and c = 4.452 with orthorhombic crystal structure and monophase nature were analyzed by powder x-ray diffraction. Raman spectroscopy revealed the vibrational modes, and UVVis-NIR spectroscopy was used to study the direct nature of optical absorption with a band gap of 1.14eV. The currentvoltage (I-V) characteristics of the semiconductor diode were measured in room temperature (25C) and revealed rectifying properties and the cut-off voltage for the device, 0.57V. The obtained results highlight that the use of a p-SnSe1-xOx (SSO) layer as an interface between n-CdS/Au diodes exhibits excellent rectifying behavior and enhanced diode performance. Therefore, the p-SSO layer is a suitable material for heterojuction diodes and optoelectronic switches.

Study of nanofluid flow and heat transfer in a stationary cone-disk system
Rheometric, viscosimetric, bio-medical, and several other pharmaceutical machineries utilize the structural advantages provided by the geometry of a stationary conical diffuser. The problem of the Buongiorno nanofluid flow in the conical gap of a stationary cone-disk system for isothermal boundaries is studied. The governing system, comprising the incompressibility condition, NavierStokes equation, energy conservation equation, and conservation of Nanoparticle Volume Fraction (NVF) equation, is analyzed. The Lie-group theory has been used to derive a self-similar model. Solutions of the self-similar equations were computed numerically, and the expressions for the Nusselt number and Sherwood number are obtained. The parametric investigation reveals that the heat and mass transfer rate subside significantly when pre-swirl is introduced to the flow. Furthermore, the nanofluid slip mechanisms enhance the effective temperature of the system. 2023 Elsevier Ltd
