An Exploration of Baby Boomer Mass Retirement Effects on Information Systems Organizations

The potential knowledge loss from Baby Boomer generation employee retirements can negatively affect information systems organizations. The purpose of this hermeneutic phenomenology study was to explore the lived experiences of the leaders and managers of information systems organizations as they tried to maintain operational continuity after Baby Boomer worker retirements. The impact of this issue was the operational continuity after the Baby Boomer worker retirement. The social impact of this issue was the knowledge loss events that might result in business loss or even bankruptcy. McElroy\u27s knowledge life cycle model was the conceptual framework for this study that included knowledge production and knowledge integration processes within a feedback loop. The lived experiences of 20 knowledgeable participants who had experienced institutional knowledge loss from retired Baby Boomer generation employees were captured through purposeful sampling. Data were collected through individual interviews using either face-to-face or a web conferencing tool such as Skype and analyzed through a modified Van Kaam. Five themes were identified: business climate, delivery practices, work processes, camaraderie, and management response. Significant attributes that added to the body of knowledge were workplace navigation, alternate focus, and outsourcing management. The results of the study may enable organizations to be better able to understand and manage the Baby Boomer knowledge loss effects and subsequently create systems to help maintain their competitive edge and avoid knowledge loss that might result in business loss or even bankruptcy

Pathways towards reverse logistics adoption in Indian educational institutes: a challenging factors analysis

Reverse logistics (RL) has been proven to have a positive effect on addressing the issue of effectively utilizing resources. India has a population of over one billion people with most of it dominated by youth. Developing RL strategies and exposing it to students will encourage them to find ways to manage the limited resources available in our country. This study is focused on identifying the challenges of RL implementation in education institutes in India and finding the inter-relationship among them. The most crucial barrier to RL implementation in educational institutes is also sought in the process. We initially review the RL practices in the Indian sub-continent to examine the challenges of effectively implementing RL. We then identify the challenges of RL based on literature and discussions with experts from the education industry. The experts selected for this study include administrators from schools and universities in Kerala, India (South India). A survey was conducted in two phases. The Fuzzy-DEMATEL technique was applied to determine the inter-relationship between the challenges and obtain the causal diagram. Initially, 45 challenges were identified. Based on responses from experts from phase one of the survey, it was narrowed down to 29 crucial challenges. A pairwise comparison among the challenges was then done by experts in the education field. Finally, on the application of Fuzzy-DEMATEL, a causal diagram was generated to indicate the extent of influence of the RL challenges. Our findings indicate that educational institutions are faced with lack of awareness about reverse logistic, lack of responsibilities about environment, resistance to change, lack of supplies on supplier end, lack of knowledge, and no proper outlet for disposal in managing RL operations in educational institutes. The challenges identified in our study is unique to the Indian sub-continent and provides a result based on the current scenario of RL implementation in Indian educational institutes. The findings from our study indicate a unique perspective of RL implementation challenges. We analyzed 29 challenges to obtain our findings. Furthermore, we use Fuzzy-DEMATEL as our analysis tool to facilitate finding results. We present this as the uniqueness of our study from the available literature

Rapid detection of Ganoderma lucidum and assessment of inhibition effect of various control measures by immunoassay and PCR

Molecular and immunological methods have been applied for detecting the Ganoderma disease of coconut. Polyclonal antibodies (PAbs) raised against basidiocarp protein of Ganoderma were used for detection. For polymerase chain reaction (PCR) test, the primer generated from the internal transcribed spacer region one (ITS 1) of ribosomal DNA gene of Ganoderma, which produced a PCR product of 167 bp in size is used for early detection. Ganoderma disease in apparently healthy palms in two coconut gardens was tested by ELISA test using basidiocarp protein antiserum. Field trials were laid out in these early-diagnosed palms for the management of the disease. Based on the ELISA results,Pseudomonas fluorescens + Trichoderma viride with chitin amended treatments arrested the multiplication of the pathogen and showed below the infection level of optical density (O.D) within six months. Integrated disease management (IDM) and fungicide tridemorph treated palms showed below infection level (O.D value) within seven months and T. harzianum and P. fluorescens + T. viride treatedpalms showed below infection level (OD value) of the disease in eighth months

A rare case of patellar fracture with quadriceps tendon rupture

Quadriceps tendon rupture is the rarest injury with an incidence of 1.37/1,00,000/year. A patellar fracture is the most common injury associated with extensor mechanism lag, but it is rarely found to have quadriceps rupture rather than patellar tendon rupture. Normally when patella fracture occurs the force is disseminated at the bone level rather than at the muscular level. In this case, the force has disseminated at both muscle and bone leading to fracture of patella and quadriceps tendon rupture. Here we report a case of patellar fracture along with quadriceps tendon rupture

Applying Reflexivity to Artificial Intelligence for Researching Marginalized Communities and Real-World Problems

Despite advances in artificial intelligence (AI), ethical principles have been overlooked, harming marginalized communities. These flaws are due to a lack of critical insight into the complex positionality of the researcher, power dynamics between scholars and the communities being studied, and the structural impact on real-world problems when AI systems appear to be accurate but ethically fail. Reflexivity is a process that yields a better understanding of community-specific nuances, areas requiring local expertise, and the potential consequences of scholastic interventions for real-world problems (i.e., social, environmental, or socioeconomic). The paper builds on the five stages of social work reflexivity that can be applied to AI researchers and provided questions that can be asked in order to increase privacy, accountability, and fairness. We discuss the effective implementation of reflexivity in research, detail the stages of social work reflexivity and highlight key questions for AI researchers to ask throughout the research process

Parameter uniform convergence of a finite element method for a singularly perturbed linear reaction diffusion system with discontinuous source terms

A linear system of ’n’ second order ordinary differential equations of reaction-diffusion type with discontinuous source terms is considered. On a piecewise uniform Shishkin mesh, a numerical system is built that employs the finite element method. The numerical approximations obtained by this approach are proven to be effectively almost second order convergent

Circular slot antenna for triband application

We recommend a circular monopole antenna (CMPA) with a central feed to operate in three bands. The antenna is circular and has an 8cm diameter. The suggested antennas' resonance frequency ranges are 2.43 GHz, 5.24 GHz, and 9.61 GHz. The planned CMPA is made up of two circle-shaped slots cut into the radiating patch. The whole structure is supplied via a microstrip feed line and analysed using CST Studio's electromagnetic simulator, which is based on finite integral technique (FIT). To check the structure, the return loss, radiation pattern, voltage standing wave ratio (VSWR), and gain are all examined. The structure's ideal dimensions are determined using a parametric study of three factors: feed position, feed breadth, and ground size. The proposed CMPA is capable of operating in several bands and has good matching impedance in all of them
