Pulse Shaper Design for UWB-Based Medical Imaging Applications
In this paper, a pulse shaping filter is designed to shape the higher-order derivatives of the basic UWB Gaussian pulse for efficient pulse transmission through human tissues for medical imaging applications. The shaped pulse for the desired center frequency fits the FCC mask and power spectral density (PSD) specifications with higher spectral efficiency being achieved. It is observed that the ringing effect of Gaussian pulse is reduced by using the proposed bandpass FIR shaping filter. The low ringing effect observed in the shaped pulse ensures better antenna power distribution and improved location accuracy which is critical factor for medical imaging applications. The pulses synthesized are highly orthogonal which aids in multi-access communication, improved bit error rate (BER) performance and short duration UWB pulses leading to higher data rate transmission. The drooping frequency response characteristics of the synthesized pulse have reduced clutter hence tightly focused image obtained for imaging applications. 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. -

Publication stress amongst scholars and faculties: a concern of mental health
Purpose: The purpose of this paper is to explore the impact of the seemingly entrenched culture of publish or perish on academics and lecturers mental health in academia. From an autoethnographic perspective, personal experiences of stress, anxiety and burnout are articulated and considered in terms of broader system issues within academia. Design/methodology/approach: Using personal reflections on publication pressure and combining that with the broader existing literature on mental health in academia, this paper, like the ones mentioned above, has been written with autoethnography as the research mode. Autoethnography is a research method that allows for profoundly exploring personal experiences but frames them in a broader academic context, thereby allowing for a qualitative analysis of academics mental health challenges. Findings: The pressure to publish in high-impact journals puts a person under a level of mental health stress that includes feeling anxious, feeling like an impostor and suffering from burnout. Therefore, this very unfitting competitive environment requires institutional support and strategies to mitigate the stress associated with publication. Originality/value: This paper offers an autoethnographic view of the mental health difficulties in academia, providing a firsthand account of the emotional toll of academic publishing. This paper fleshes out the burgeoning discourse surrounding mental health within higher education by connecting personal experiences with systemic issues, pointing to changes in culture and structure. 2024, Emerald Publishing Limited. -
Public-Private Partnership Ventures: A Diasporic Initiative in India Through Social Remittances and Philanthropic Work
Diaspora networks across the globe think of their homeland, which makes them continuously assist various projects that have public-private partnership ventures. Many of the members of the Indian diaspora had difficult times during their childhood in their native country. The conditions were not favorable within India prior to Indian Independence for acquiring desired skills in entrepreneurial activities. However, they managed to sail through the rough sea and reach the western coast in great adversity. The journey itself was a training for the early diaspora that resulted in learning the skills needed for setting up their business in the adopted countries. Indian diaspora from various developed countries have learned a great deal about the local culture, new skills in business partnership, consultancy services, research and innovations in technology that helped them to prosper in the adopted land and implement those ideas in their home country as a part of social remittances and giving back to the society. Developed countries have exhibited the feasibility of sustainable development through social entrepreneurship. Compulsory community service that trains people in new skill development also educates them in preserving the environment in which they reside. The public-private partnership model, which is in practice in developed countries, has become the agent of creation of social entrepreneurship with accountability toward the society. Diaspora communities that send social remittances to their home countries not only in the form of money but also ideas, identities and behaviors help set up public- private models of undertakings that would ensure sustainable growth in the long run. Philanthropic work is reckoned in the Public-Private Partnership (PPP) model that we see in various parts of India, especially in states like Punjab (Sikh diaspora), Kerala (Malayali diaspora) and Gujarat (Gujarati diaspora). In this background, this chapter tries to examine the Indian diasporas schemes in India on the model of public-private partnership that they had either set up or observed in their adopted countries. This chapter also looks into how far diaspora remittances in totality help mitigate the existing problems in Indian villages, create new job opportunities for the local population, manage skill development centers and educate the masses in preserving the environment that would help in sustainable development through social entrepreneurship. 2024 by World Scientific Publishing Co.

PUBLIC DEBT AND ECONOMIC GROWTH IN INDIA
With the intention of stabilizing economy and to stimulate economic growth rate the modern day governments are presenting un balanced government budgets. This is increasing the growth of public debt. This deficit can be bridged by increasing the existing rates in taxes, imposing new taxes, and borrowing from public. The objectives of this study are 1) Analyzing the trends of public debt in India. 2) Analyzing the components of internal debt of India. 3) To find the threshold point of public debt to gross domestic product (GDP) ratio in India. 4) To investigate the connection among public debt and economic growth rate in India. Time period is 1981-2011-2012 and study used statistical tools and econometric techniques like percentage, R square, Adjusted R square, linear regression, and unit root test. Results show that there is an increasing trends in public debt of India. Regression result showed that 60 percent is the threshold point of public debt to GDP ratio and unit root test cleared that no need to check connection among public debt and gross domestic product. -
Public debt - economic growth nexus in emerging and developing economies: Exploring nonlinearity
This paper explores the nonlinear dynamics between public debt and economic growth by estimating the threshold level of debt for thirty-nine emerging and developing economies. The study found a considerable variation amongst the debt thresholds in these countries, ranging between 24 and 132 per cent. We observed the evidence for an inverted U-shape relationship either partially or fully only in six countries. On the contrary, our study found that expanding debt even beyond the threshold promotes economic growth in some countries, while debt hinders growth even at low debt levels in a few countries. 2022 Elsevier Inc. -

Pt Nanospheres Decorated Graphene-?-CD Modified Pencil Graphite Electrode for the Electrochemical Determination of Vitamin B6
An electrochemical sensor for Vitamin B6 determination has been prepared by the electrochemical deposition of Pt nanospheres on graphene-?-CD coated Pencil Graphite Electrode (PGE). Cyclic voltammetric (CV) and electrochemical impedance spectroscopic (EIS) studies were employed to explore the electrochemical properties of the modified electrode. The physicochemical properties of the modified electrodes were characterized by X-ray photoelectron spectroscopy (XPS), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and optical profilometric studies. The experimental conditions such as effect of scan rate, concentration and pH were optimized. The linear dynamic range for the determination of Vitamin B6 was found to be 5nM to 205nM. The low level of detection limit (1.2nM) implies the high sensitivity of the process. The suggested method was effectively employed for the electrocatalytic evaluation of Vitamin B6 in different juice samples.

Pt nanoflower-poly(aniline) electrode material with the synchronized concept of energy storage in supercapacitor /
Applied Surface Science, Vol.589, ISSN No: 0169-4332.
Electrochemically deposited porous film of poly(aniline) (PANI) on stainless steel (SS) current collector is employed as the support for electrodeposition of platinum (Pt). PANI facilitates the formation of Pt nanoflowers with an enhanced electrochemically active surface area compared with sub-micron size Pt particles deposited on the bare SS electrode. Hence, a new concept Pt nanoflower-PANI electrode materials with synchronization between redox mode in PANI and double-layer mode of charge storage in Pt nanoflower is discussed. Remarkably, Pt is distributed like a nano-flower on the surface of PANI and prevents PANI from stripping during the charge-discharge process, thereby minimizing the issue of stripping in conducting polymer-based electrodes. -

Remarkably, Pt is distributed like a nano-flower on the surface of PANI and prevents PANI from stripping during the charge-discharge process, thereby minimizing the issue of stripping in conducting polymer-based electrodes. Owing to the highly porous surface morphology of Pt nanoflowers as observed in SEM, the Pt-PANI/SS electrode shows excellent electrochemical performance than PANI/SS electrode towards supercapacitor application. The electrode materials are characterized using X-ray and X-ray photon spectroscopy (XPS), which shows dual amorphous and crystalline properties. Dielectric studies of Pt-PANI/SS electrodes were carried out to understand electrode/electrolyte interface behavior. In the fabricated supercapacitor, the cyclic voltammetry studies showed quasi-rectangular shape characteristics at slower scan rates with a specific capacitance of 926 Fg?1. Charge-discharge studies showed good cyclic stability and coulombic efficiency. 2022 Elsevier B.V. -

Psychosocial Well-Being of Adolescents : A Social Group Work Intervention
Social work practice with children and families is one of the most challenging, skilled and rewarding areas of social work practice. Social workers believe that safeguarding children and preventing them from significant harm is a rewarding and challenging way to make a difference in the life of a child, which involves the corporation, consultation and collaboration of many people working effectively together. As highlighted by the United Nations' data disaggregation against the goal of "no one left behind," the absence of data on adolescents needs research on the "second decade." Furthermore, because India has the world's largest adolescent population, studies and policies aimed at developing adolescents' competencies are critical to the country's development; interventions aimed at instilling confidence in underprivileged adolescents to strive for a better future are critical for mitigating inequity. Adolescents from disadvantaged families and whose parents are no longer able to provide adequate care to children are having various psychosocial problems, high risk of violence, exploitation, abuse and neglect and their psychosocial well-being is often insufficiently monitored. This intervention study adopted a quasi-interventional design to measure the effectiveness of social group work in raising the psychological well-being, self-esteem and coping orientation of adolescents in child sponsorship programs. Social group work intervention with 20 sessions was designed in response to the information garnered through the pilot study and administered to the intervention group (n=20). Conducted pre-test and post-test for both intervention group and control group (n=20) and two follow up tests in three months intervals for the intervention group (n=20) using 42 item version of Ryffs scale for psychological well-being, Rosenbergs 10 item self-esteem scale and 54 items A-COPE scale; and data analyzed using SPSS. Comparison between pre and post measurements carried out using paired sample t-test for the intervention group and control group separately, gave out a p value < 0.05 for the intervention group and, > 0. 05 for the control group. Thus, it was proved that the psychological well-being, self-esteem and coping orientation of participants in the intervention group were raised significantly due to the social group work intervention. Applying refined granularity, this research adds data specifically on adolescents enrolled in child sponsorship programs and sets a blueprint for social group work to raise their psychological well-being, self-esteem and coping orientation. Proposing a conceptual framework for child sponsorship programs, this study recommends the need for operational tie-ups, sustained youth support, training of trainers (ToT) for community animators, preparing individual care plans and training to school social workers and the need of starting walk-in counselling centres and mentoring services. Furthermore, this study suggests additional research in all aspects of its operation, as well as interventions at the group, family, and community levels, for the well-being and empowerment of marginalised adolescents. -

Psychosocial correlates of resilience among older adults in Mexico
There is a tremendousglobal increase in the older adultspopulation. Mental health in older age is as important in as it is for other age categories. Majority of older adults show healthy states, vitality, good humor and enthusiasm in performing various activities, interest in continuing to contribute to their family and society despite the difficulties of this stage of life due to large part to resilience they have. The aim of the study was to establish social and psychosocial factors associated with resilience.A cross-sectional and correlation study was conducted on older adults who were hospitalized in a public General Hospital of Mexico in 2013. Resilience, gender, occupation, family environment, self-esteem, presence of critical life events, and the presence of significant persons were assessed. 186 older adults participated. Higher levels of resilience were found in males and employed people. Participants with a functional family and high self-esteem had the highest levels of resilience. Besides, 15% of the variance of the total resilience score was explained by family environment, and 27% was explained by self-esteem (p<0.05).Although all participants were older adults, individual characteristics such as gender, occupation and self-esteem; besides family environment, were found to be associated to the levels of resilience in this population. Specific programs- -enhancing these factorsare needed to improve resilience. 2019 Oriental Scientific Publishing Company. All rights reserved. -

Psychometric Properties of the Moral Injury Symptom Scale Among Indian Healthcare Professionals
The spread of the novel coronavirus has led to a rise in morally conflicting situations for healthcare professionals. Doctors and nurses who were serving as frontline workers, require special attention to alleviate the long-lasting impact of the potentially morally injurious events. The current study aims to validate the Moral Injury Symptom Scale-Healthcare Professionals (MISS-HP) among Indian healthcare workers. The 10-item MISS was administered to 150 doctors and 150 nurses using the purposive sampling method. Firstly, reliability was assessed using internal consistency measure. Secondly, item discrimination index was assessed by calculating the point biserial correlation for each item. Cronbach alpha indicated high internal consistency (0.77). The point biserial correlation value for each item indicated good discrimination. Finally, confirmatory factor analysis (CFA) was performed to replicate the factor structure. CFA results suggested a good fit to the data. In conclusion, MISS-HP is a reliable and valid tool to assess moral injury among Indian healthcare professionals in India. 2023 Hibino et al. -
Psychometric Properties of the Interpersonal Emotion Regulation Questionnaire Among Couples in India
The aim of the present study was to translate the Interpersonal Emotion Regulation Questionnaire (IERQ) into the Tamil language and examine its psychometric properties in the Indian cultural context. Data were collected from a dyadic sample of 340 married heterosexual couples (N = 680) currently residing in India. The mean age of husbands was 39.57 (SD = 6.10; 26 ? range ? 58), and the wives was 35.33 (SD = 5.72; 23 ? range ? 54). Descriptive results indicated that husbands and wives reported similar levels of interpersonal emotion regulation. Confirmatory factor analysis showed a 20-item model with four factorsenhancing positive affect, perspective-taking, soothing and social modeling, similar to the original version, fits the data well. Furthermore, the multiple-group analysis indicated robust measurement invariance across gender (husbands vs. wives), family type ( joint vs. nuclear) and marriage type (arranged vs. love), indicating that the Tamil version of the IERQ operates similarly across these groups. Besides, the Tamil version of the IERQ showed good convergent and discriminant validity with measures of dyadic coping and relationship satisfaction. Implications for research and couples therapy in the Indian cultural context are discussed. 2022, PsychOpen. All rights reserved. -
