Mechanics of SH and anti-plane SH waves in orthotropic piezoelectric quasicrystal with multiple surface effect
Significant restrictions have been found in the selection of piezoelectric materials and the direction of wave propagation in earlier studies on surface acoustic wave sensors. The primary goal of the current work is to investigate how wave propagation direction influences the performance of SAW macro- and nano-sensors in an effort to remove such barriers in the technological revolution of SAW sensors. A proposed model is established to study Shear Horizontal (SH) and anti-plane SH wave propagation in piezoelectric materials with surface effects. The theoretical forms are constructed and used to present the wavenumber of surface waves in any direction of the piezoelectric medium, based on the Extended Stroh formalism. In addition, we take into account surface elasticity theory in order to obtain the phase velocity equation based on the wavenumber expression. The model incorporates surface elasticity, piezoelectricity, and permittivity to account for nanoscale surface phenomena. Two configurations are examined: an orthotropic piezoelectric material layer over an elastic framework and a piezoelectric material half-space with a nano substrate. Analytical expressions for frequency equations are derived for both symmetric and anti-symmetric waves. Numerical results highlight the critical thickness of the piezoelectric layer, where surface energy significantly influences dispersion properties. The effects of surface elasticity and density on wave velocity are analyzed, revealing a spring force-like influence on boundaries. The research investigates SH wave transmission in anisotropic, transversely isotropic piezoelectric nanostructures. The findings could aid in designing SAW devices and piezoelectric sensors, as well as producing more effective surface acoustic wave sensors, based on recent theoretical work summaries.

Mechanistic elucidation of irreversible chemodosimetric sensing of hydrazine through structural, computational, and bioimaging analyses
A fluorescent chemodosimeter, DBA, has been developed for the selective detection of hydrazine via an irreversible reaction pathway that leads to fluorescence enhancement. The crystal structure of the ligand has been successfully determined. The sensing mechanism involves the conversion of a hydrazide derivative into a hydrazone derivative, as confirmed by both 1H NMR and mass spectrometry. Upon interaction of DBA with hydrazine, the probe exhibits a significant decrease in absorbance at 366 nm and 279 nm, along with a three fold enhancement in fluorescence intensity at 423 nm, achieving a detection limit of 0.37 M. The detection mechanism has also been supported by theoretical analysis using density functional theory (DFT) calculations. For practical applications, DBA has been employed in plant-based cell imaging to monitor hydrazine accumulation in Lathyrus sativus L. (grass pea). Overall, DBA is a simple, effective, and promising fluorescent probe for hydrazine detection in diverse fields such as environmental monitoring, food safety, and biological risk assessment.

Mechanoluminescence of PolymerOrganic Composites under Strain and Hydrostatic Pressure
The development of underwater-based Internet of Things has drawn much attention to fluorescence sensors for crucial technological advancement. Therefore, the technologies for underwater mechanoluminescence (ML) sensing have created various applications for sensors and self-powered waterproof displays. However, developing single-molecule-based intrinsically adaptive materials capable of responding to multiple stimuli with high sensitivity remains a challenge. Herein, a flexible sensor based on the fluorescent ligand DHN was fabricated using a PVDF polymer matrix to form PVDH, enabling the exploration of external-stimuli-responsive fluorescence enhancement under mechanical strain and underwater pressure. For PVDH, the transition from crystalline to amorphous state by mechanical stimuli boosted its photoluminescence by ?75%, and stretching (strain ?16%) the sensor boosted its photoluminescence by ?145%, which is due to the formation of molecular aggregates in the amorphous state. Additionally, the increase in ML correlated with an output voltage of ?4 V of the fabricated device under mechanical stress. The in-depth density functional theory (DFT) calculations further support the experimental observation by studying the charge distribution and orbital overlapping in the DHN ligand. Furthermore, the film shows clear visualization when subject to underwater pressure and stable fluorescence upon exposure to different impurities. Therefore, this study reveals the use of fluorescence and mechanochromic properties of the ligand for designing advanced underwater sensors for visualization and communication. 2025 American Chemical Society -
Media and Urban Governance: The Quest for Sustainable Cities and Communities
Connectivity becomes the hallmark of network society facilitated by digital technologies. Cities are fundamentally well-connected, fast-growing, communicative, and global in outlook. Cities are also known for media concentration, as the structures and people there extensively create and exchange messages - social, political, economic, and cultural. The urban communication landscape is very complex, and therefore, a robust media and communication infrastructure is required to form, reform, and transform urban communities from a sustainable development perspective. Media not only perform the responsibilities of information dissemination and community building but also facilitate urban governance and public discourses on policies. The policy-making process that consists of policy inputs, policy processes, and policy outputs - is heavily influenced by the public discourses triggered by the media. Media can establish a policy issue at the center of the public sphere, set the policy agenda, and create public opinion. It inevitably leads to the mediatization of public policy. Media can effectively place SDGs at the center of the policy discourse and serve as a tool for urban governance by enhancing citizens' participation and helping to solve complex urban problems. This research paper explores various aspects of the governance-media interface in an urban landscape to create sustainable cities and communities. The Electrochemical Society -
Media Framing of Indian Green Fiscal Policy: A Survey of Environmental Policies Across Online News Portals
This research undertakes a framing analysis of news coverage from five leading Indian news portals, focusing on the environmental provisions of India's fiscal budgets for 2022-23 and 2023-24. These budgets marked a significant shift, being the first to prioritize "Energy Transition and Climate Action" and "Green Growth" as central themes. The analysis uncovers a spectrum of portrayals: from highlighting government initiatives and the potential economic windfalls of green policies to critical evaluations and concerns about their real-world implications. Specifically, the Times of India, with its 27 stories, leans heavily towards business and economic perspectives. The Hindu, through its five stories, both praises the government's green initiatives and critiques certain infrastructure projects. Hindustan Times offers a balanced view in its nine stories, juxtaposing government action plans against critiques of infrastructure spending. In contrast, The Scroll and The Wire, each with three stories, delve deeper, providing incisive, critical analyses of the government's environmental commitments. The study underscores that while independent news portals present nuanced insights, their narratives often stand in the shadow of mainstream portals that echo the government's perspective. Given the escalating global importance of environmental challenges, the findings strongly advocate for media outlets to establish dedicated environmental news sections. Such focused coverage could enhance public awareness and pressurize effective governmental action in the domain of green fiscal policies. 2023 by authors, all rights reserved. -

Purpose: This study aims to perform a systematic literature review to organize the abundance of information on employee relations (ER) and sustainable organizations. Moreover, this study identifies the research gaps by investigating the review of ER mediating and moderating variables and the relationship between ER and sustainable organizations. Design/methodology/approach: This study is based on the systematic literature review methodology involving 257 studies in the final stage. The Scopus and Google Scholar databases with search criteria employee relations and employee relations and sustainable organization were used to achieve the research objective. After applying inclusion and exclusion criteria, researchers come to the distribution of the articles based on the subthemes, geographical region, types of methods, top authors with affiliation and complete research articles based on the citation. In the final stage, this study concluded with the conceptual model comprising mediators and moderators of ER as well as the mediating and moderating variables of the relationship between ER and sustainable organizations. Findings: The reviewed literature shows that employee relation is an optimal strategy for retaining employees via proper disclosure of human resources (HRs) and ER Index. This study included the top six publishers, namely, Emerald, Elsevier, Sage, Springer, Taylor and Francis and Wiley Online Library, to do an exhaustive review on a specific topic. The findings indicate that after COVID-19, the ER index, HR disclosures and the sustainability of ER are among the new and required paradigm shifts needed to manage a crisis impact and perform productively. The mediator and moderator variables that can improve employeeemployer relationships are organizational trusts, organizational justice, perceived job satisfaction, organizational structure and firm ownership. On the other hand, variables that mediate and moderate the relationship between ER and sustainable organizations are organizational climate, organization trust, organization culture, perceived organization support, psychological empowerment, firm ownership, leadership behavior and attitude, respectively. The findings concluded that harmonious and cordial ER are pertinent in building sustainable organizations and accomplishing organizational goals. Practical implications: The mediating and moderating variables that have been identified can be helpful for enthusiastic researchers in contributing to empirical research. Practitioners and managers can use the findings in making an effective organizational model that develops good employeeemployer relationships and helps create a culture of trust and harmony. This study focuses on exploring the variables of ER, which strengthens employeeemployer relationships and supports organizations to stay agile and attain sustainability to endure in the future. Originality/value: This study insights on the specific mediating and moderating variables of ER and sustainable organizations. Till date, studies exploring constructs of ER and sustainable organizations are still in deficit. Better employee relation reflects and leads to a more resilient organization. Future researchers should explore the connection between pandemics and ER which is done insufficiently in the present time. 2022, Emerald Publishing Limited. -
Mediating Effect of Brand Relationship Quality on Relational Bonds and Online Grocery Retailer Loyalty
The current study aims to identify how brand relationship quality mediates the relationship between different online relational bonds, and attitudinal and behavioral loyalty. A total of 316 valid questionnaires from respondents aged 2035 were collected using quota sampling from five different clusters in Bangalore, India. Hypotheses were tested using structural equation modeling. This study finds that convenience bonds and structural bond have no impact on brand trust and attitudinal and behavioral loyalty. All five relational bonds namely, convenience, structural, financial, empathy, and social bonds are seen to influence their sense of community and attitudinal attachment. Sense of community is the primary influencer of brand loyalty. This study reveals that brand dimensions of brand quality relationship mediate the effect of financial, empathy, and social bonds on attitudinal and behavioral loyalty. It also illustrates the role of different relational bonds as a stimulus, and relationship quality dimensions as an organism that lead to improved customer loyalty in online grocery retailing. Managers of online grocery stores can consider these new relational bonds, along with the traditional bonds, to develop positive emotions and achieve competitive advantage. 2021 Taylor & Francis Group, LLC. -

Mediating role of resilience on the relationship between meta emotions and emotional regulation among neglected adolescents
Background: Adolescence is a pivotal stage in human development, marked by significant biological, cognitive, and emotional transformations that shape an individual's character and future behaviour. The emotional strategies and behavioural patterns inculcated during this phase become integral aspects of one's personality, influencing how one navigates through various life challenges. For vulnerable adolescents, such as neglected children in institutional care or orphans, negative life experiences can heighten the risk of developing psychological concerns. This heightened vulnerability is often exacerbated by impaired emotional regulation and low resilience, which may contribute to the emergence of internalising disorders. Methods: The present study was conducted to examine the relationship between meta emotions and difficulties in emotional regulation among neglected adolescents and to analyse the mediating effect of resilience on this relationship. The participants of the study were 667 neglected adolescents: 335 males (50.2%) and 332 females (49.8%) who belong to the age group 13 to 17years (mean age = 14.60, S.D = 1.16) years from various institutional homes across Bangalore. Results: The results of this study confirm that in the presence of increased levels of negative meta emotions in an individual, despite the mediating effects of resilience, difficulties in emotional regulation will be further worsened. This was substantiated by the positive correlation between negative meta emotion and difficulties in emotional regulation. Contrastingly, elevated positive meta emotions in an individual, along with the mediating effects of resilience, reduce the difficulties in emotional regulation. This was also reinforced by the strong relationship between positive meta emotions and difficulties in emotion regulation. Conclusion: The findings of the study highlight the prevalence of increased negative meta emotions and poor emotional regulation among neglected adolescents, which is of utmost importance from a psychological, social and policy-making perspective. This calls for the need for tailored and individual-focused interventional strategies to improve the psychological health of these vulnerable children. Moreover, the critical period of adolescence is a crucial time for implementing effective policies in order to shape the behavioural and cognitive aspects of personality with much-needed care, support, and professional guidance.

Mediating role of self-concept on character strengths and well-being among adolescents with specific learning disorder in India
Background: Adolescents with Specific Learning Disorder (SLD) are at higher risk of academic underachievement, stigmatization, and mental health issues. However, the complete elimination of disorder-related deficits and external challenges is an impracticable solution for enhancing their well-being. Aim: The study adopts a strength-based approach to understand the role of an innate factor, i.e., self-concept, in the association between character strengths and well-being of adolescents with SLD. Methods: A correlational research design following a mediation analysis was adopted to examine the association between the study variables on a sample of 115 adolescents with SLD from India. Results: Self-concept functioned as a partial mediator between the life-satisfaction construct of well-being and six character strengths: Appreciation of beauty and excellence, Perseverance, Judgment, Leadership, Perspective, and Zest. Gender differences were identified with regard to the study variables. Conclusions and implications: Self-concept of adolescents with SLD could partly contribute to enhanced character strengths awareness to protect well-being. Further, the crucial role of internal factors like self-concept and character strengths in improving the well-being of this population was highlighted. Thereby encouraging future research on SLD to adopt approaches that focus on innate strengths rather than deficits and external sources of well-being. 2022 Elsevier Ltd -
Mediating role of teacher confidence between support system and satisfaction
Online education in India has witnessed a shift due to the ongoing pandemic, compelling the Indian education sector to adapt to new advancements. The study's main purpose has been to find the relationship between the support systems of institutions, teachers support and students, leading to instructors' satisfaction. It further analyses the mediating role of educators' confidence in linking support systems and leading to teachers' satisfaction. The sample for our research consisted of 129 teachers from Higher Educational Institutions (HEIs). We found that there is a significant relationship between support systems and teacher satisfaction. Among the three support systems, institutions support had a significant influence. On the other hand, teachers' confidence had a partially mediating effect on their satisfaction, even though they could translate to higher effectiveness in online teaching. Further, this study inferred that educational institutions are quick to adapt to online teaching due to the ongoing pandemic. Copyright 2022 Inderscience Enterprises Ltd. -
Mediation of Perceived Innovation Characteristics on ERP Adoption in Industrial Cluster
An industrial cluster, due to its close network of institutions, will experience various pressures that force the industry to have a homogeneous structure, norms, and practices. These pressures can also lead to adoption of innovative technologies. Enterprise Resource Planning (ERP) is perceived as a sophisticated technology and diffuses across the cluster by its innovative characteristics. However, firms in the industrial cluster will have different rate of adoption of technologies due to the varying level of knowledge spillover and a heterogeneous absorptive capacity. This study empirically tests how absorptive capacity mediates the institutional forces and the perceived innovation characteristics towards the ERP adoption in an industrial cluster. Mediation effect and the model validity are tested using SEM technique. The results show that absorptive capacity complements the forces of institutional pressure and the perceived innovation characteristics on ERP adoption. The implications of managing the absorptive capacity for better ERP adoption are discussed. 2016 World Scientific Publishing Company. -

Medical aptitude and its assessment
The assessment of the suitability of an individual for the profession of medical science is carried out worldwide on the basis of several yardsticks. While a few methods assess domain knowledge of sciences, others focus on evaluating the cognitive aptitude skills of the candidate, while few others assess communicative skills. Though it has been considered that the possession of an aptitude for the profession is a prerequisite, considering its strenuous demands from the candidate, a comprehensive assessment of these areas under the construct of medical aptitude has not been analysed so far, though medical aptitude has been socially defined. This article attempts to develop a comprehensive construct to Medical aptitude, meant for the pre-medical student, which has been encapsulated with respect to the areas of its assessment. We did an extensive survey of the literature pertaining to the mode of selection of students towards medical profession and analysed their areas of assessments for admittance. This enabled to identify similarities in the areas of assessment which were then classified under several domains of assessment. Special reference to the keywords involving Aptitude and Medical Aptitude was made. We analysed the definitions to the construct of aptitude from the literature with respect to its relevance in the profession of medical science to be possessed by the premedical aspirantin context. From this, a new construct of medical aptitude was formulated incorporating the existing construct of medical aptitude. Medical aptitude is a comprehensive construct that encompasses the dimensions of a consistent core, a peripheral content and the support of a scaffold. Each of these dimensions have their importance and distinct objective in being assessed in the pre-medical student. A perfect intertwining of these 3 dimensions can prove beneficial in assessing individuals to be fit for the profession of medical science. The National Medical Journal of India 2018.
