What Drives or Decelerates Generation Z? An Empirical Study Navigating Consumer Buying Intentions in Online Shopping
This study provides a comprehensive exploration of factors impacting the online buying intentions of Generation Z consumers by studying perceived risk, perceived usefulness, perceived ease of use, perceived privacy and perceived security, customer trust, and trust toward sellers. Furthermore, the study augments the Technology Acceptance Model (TAM), which can assist in formulating marketing strategies for online marketers and companies to enrich their online shopping platforms and entice more Generation Z consumers. This study employed a quantitative research approach to explore how perceived risk, perceived usefulness and perceived ease of use, perceived privacy and perceived security, customer trust, and trust toward sellers impact online buying intentions among Generation Z consumers. The data were collected employing a 5-point Likert scale questionnaire and analyzed using the SmartPLS software. Generation Z consumers’ online buying intentions are directly impacted by perceived risk, perceived usefulness, perceived ease of use, perceived privacy and perceived security, customer trust, and trust toward sellers. Applying these factors, the TAM model augmented the theoretical understanding of the online buying intentions of Generation Z consumers in the Indian context. Companies and marketers can employ the study’s insights to develop targeted online marketing campaigns that cater to the manifold needs of Generation Z consumers. The study furnishes a theoretical perspective of the intricate interplay of factors impacting consumers’ online buying intentions. The study on Generation Z consumers’ online buying intentions had several limitations, including a small sample size, quantitative technique, and geographical context limited to India.

ACC deaminase producing rhizobacterium Enterobacter cloacae ZNP-4 enhance abiotic stress tolerance in wheat plant
Plant growth promoting rhizobacterium (PGPR) designated as ZNP-4, isolated from the rhizosphere of Ziziphus nummularia , was identified as Enterobacter cloacae following 16S rRNA sequence analysis. The isolated strain exhibited various plant growth promoting (PGP) traits. The 1-aminocyclopropane-1-carboxylic acid deaminase (ACCD) activity was evaluated under diverse physiological conditions that could be useful for minimizing the abiotic stress-induced inhibitory effects on wheat plants. The strain showed resistance to salt (NaCl) and metal (ZnSO 4 ) stress. The effect of E . cloacae ZNP-4 on the augmentation of plant growth was studied under salinity stress of 150 mM (T1 treatment) & 200 mM (T2 treatment) NaCl. The inoculation of strain ZNP-4 significantly improved the various growth parameters of wheat plant such as shoot length (41%), root length (31%), fresh weight (28%), dry weight (29%), photosynthetic pigments chlorophyll a (62%) and chlorophyll b (34%). Additionally, the strain was found to be efficient for minimizing the imposed Zn stress in terms of improving plant growth, biomass and photosynthetic pigments in pots containing different levels of metal stress of 150 mg kg -1 (treatment T1) and 250 mg kg -1 (treatment T2). Isolate ZNP-4 also improved the proline content and decreased malondialdehyde (MDA) level under both salinity and metal stress, therefore maintaining the membrane integrity. Furthermore, bacterial inoculation increased the activities of antioxidative enzymes such as superoxide dismutase (SOD), catalase (CAT), and peroxidase (POX). The positive effects of PGPR occurred concurrently with the decrease in abiotic stress-induced reactive oxygen species (ROS) molecules such as hydrogen peroxide (H 2 O 2 ) and superoxide (O 2 - ) contents. Overall, the observed results indicate that use of bacteria with such beneficial traits could be used as bio-fertilizers for many crops growing under stress conditions.

Prevalence and Associated Risk Factors of Hypertension: A Cross-Sectional Study in Urban Varanasi
Hypertension is a major public health problem and important area of research due to its high prevalence and being major risk factor for cardiovascular diseases and other complications. Objectives. (1) To assess the prevalence of hypertension and its associated factors and (2) to estimate awareness, treatment, and adequacy of control of hypertension among study subjects. Methods and Materials. A community based cross-sectional study with multistage sampling design was conducted among urban population of Varanasi. A modified WHO STEPS interview schedule on 640 study subjects aged 25–64 years was used. Results. The prevalence of hypertension was 32.9% (male: 40.9%, female: 26.0%). Mean systolic and diastolic BP were 124.25 ± 15.05 mmHg and 83.45 ± 9.49 mmHg, respectively. Higher odds of being hypertensive were found in male subjects, eldest age group, married subjects, subjects of upper socioeconomic status, illiterate subjects, and retired subjects. Tobacco and alcohol consumption, overweight, obesity, and abdominal obesity were also associated with hypertension. Out of the total hypertensive 211 subjects, only 81 (38.4%) were aware about their hypertension status; out of those, 57 (70.4%) were seeking treatment and 20 (35.08%) had their blood pressure adequately controlled. Conclusion. Around one-third of the subjects were hypertensive and half of the study subjects were prehypertensive in this area. The awareness, treatment, and control of high blood pressure were also very low.

Literature Review of Shared Value: A Theoretical Concept or a Management Buzzword?
Porter and Kramer (Harv Bus Rev 84(12):78–92, 2006; Harv Bus Rev 89(1/2), 66–77, 2011) introduced 'shared value' as a 'new conception of capitalism,' claiming it is a powerful driver of economic growth and reconciliation between business and society. The idea has generated strong interest in business and academia; however, its theoretical precepts have not been rigorously assessed. In this paper, we provide a systematic and thorough analysis of shared value, focusing on its ontological and epistemological properties. Our review highlights that 'shared value' has spread into the language of multiple disciplines, but that its current conceptualization is vague, and it presents important discrepancies in the way it is defined and operationalized, such that it is more of a buzzword than a substantive concept. It also overlaps with many other (related) concepts and lacks empirical grounding. We offer recommendations for defining and measuring the concept, take a step toward disentangling it from related concepts, and identify relevant theories and research methods that would facilitate extending the knowledge frontier on shared value.

Re-evaluating supply chain integration and firm performance: linking operations strategy to supply chain strategy
Purpose
This paper aims to explore the performance implications of supply chain integration (SCI) taking a strategic perspective. Thus, this paper is set to provide answers to the following research questions: Does a higher degree of SCI always lead to greater firm performance improvements? As the answer to this question is likely to be no, the authors explore the performance implications from a strategic perspective: Is the SCI–performance relationship contingent on a company’s competitive priorities (i.e. operations strategy)?
Design/methodology/approach
The authors explore their questions through multiple quasi-independent data sets to test the impact of SCI on firm performance. Furthermore, the authors provide a more nuanced conceptual and empirical view to explore the previously uncovered contradictory results and contingent relationship challenging the “more integration equals higher firm performance” proposition.
Findings
The results only provide partial support for the proposition that more integration is always beneficial in the supply chain context. The authors also identified that the impact of SCI on financial performance is contingent on a company’s competitive priorities.
Originality/value
This study provides a much-needed comprehensive assessment of the SCI–performance relationship through critically re-evaluating one of the most popular propositions in the field of supply chain management. The results can be extrapolated beyond the dyad, as the authors conceptualise integration simultaneously from an upstream and downstream perspective.

The Multifarious PGPR Serratia marcescens CDP-13 Augments Induced Systemic Resistance and Enhanced Salinity Tolerance of Wheat (Triticum aestivum L.)
The present study demonstrates the plant growth promoting (PGP) potential of a bacterial isolate CDP-13 isolated from 'Capparis decidua' plant, and its ability to protect plants from the deleterious effect of biotic and abiotic stressors. Based on 16S rRNA gene sequence analysis, the isolate was identified as Serratia marcescens. Among the PGP traits, the isolate was found to be positive for ACC deaminase activity, phosphate solubilization, production of siderophore, indole acetic acid production, nitrogen fixation, and ammonia production. CDP-13 showed growth at an increased salt (NaCl) concentration of up to 6%, indicating its potential to survive and associate with plants growing in saline soil. The inoculation of S. marcescens enhanced the growth of wheat plant under salinity stress (150-200 mM). It significantly reduced inhibition of plant growth (15 to 85%) caused by salt stressors. Application of CDP-13 also modulated concentration (20 to 75%) of different osmoprotectants (proline, malondialdehyde, total soluble sugar, total protein content, and indole acetic acid) in plants suggesting its role in enabling plants to tolerate salt stressors. In addition, bacterial inoculation also reduced the disease severity caused by fungal infection, which illustrated its ability to confer induced systemic resistance (ISR) in host plants. Treatment of wheat plants with the test organism caused alteration in anti-oxidative enzymes activities (Superoxide dismutase, Catalase, and Peroxidase) under various salinity levels, and therefore minimizes the salinity-induced oxidative damages to the plants. Colonization efficiency of strain CDP-13 was confirmed by CFU count, epi-fluorescence microscopy, and ERIC-PCR-based DNA fingerprinting approach. Hence, the study indicates that bacterium CDP-13 enhances plant growth, and has potential for the amelioration of salinity stress in wheat plants. Likewise, the results also provide insights into biotechnological approaches to using PGPR as an alternative to chemicals and pesticides.

A high density GBS map of bread wheat and its application for dissecting complex disease resistance traits
Background
Genotyping-by-sequencing (GBS) is a high-throughput genotyping approach that is starting to be used in several crop species, including bread wheat. Anchoring GBS tags on chromosomes is an important step towards utilizing them for wheat genetic improvement. Here we use genetic linkage mapping to construct a consensus map containing 28644 GBS markers.
Results
Three RIL populations, PBW343 × Kingbird, PBW343 × Kenya Swara and PBW343 × Muu, which share a common parent, were used to minimize the impact of potential structural genomic variation on consensus-map quality. The consensus map comprised 3757 unique positions, and the average marker distance was 0.88 cM, obtained by calculating the average distance between two adjacent unique positions. Significant variation of segregation distortion was observed across the three populations. The consensus map was validated by comparing positions of known rust resistance genes, and comparing them to wheat reference genome sequences recently published by the International Wheat Genome Sequencing Consortium, Rye and

genomes. Three well-characterized rust resistance genes (

) and 15 published QTLs for wheat rusts were validated with high resolution. Fifty-two per cent of GBS tags on the consensus map were successfully aligned through BLAST to the right chromosomes on the wheat reference genome sequence.
Conclusion
The consensus map should provide a useful basis for analyzing genome-wide variation of complex traits. The identified genes can then be explored as genetic markers to be used in genomic applications in wheat breeding.

Supply chain management: a structured literature review and implications for future research
Purpose - The field of supply chain management (SCM) has historically been informed by knowledge from narrow functional areas. While some effort towards producing a broader organizational perspective has been made, nonetheless, SCM continues to be largely eclectic with little consensus on its conceptualization and research methodological bases. This paper seeks to clarify aspects of this emerging perspective.Design methodology approach - A total of 100 randomly selected refereed journal articles were systematically analyzed.Findings - A number of key findings emerged: the field is a relatively \"new\" one; several disciplines claim ownership of the field; consensus is lacking on the definition of the term; contextual focus is mostly on the manufacturing industry; predominantly \"process\" conceptual framing prevails; research methods employed are mostly analytical conceptual, empirical surveys or case studies; the positivist research paradigmatic stance is prevalent; and theories related to transaction cost economics and competitive advantage dominate.Originality value - This review identifies various conceptual and research methodological characteristics of SCM. From a philosophy of knowledge perspective, it is suggested that SCM be framed as a Lakatosian Research Program, for this has the best potential to assist in the development of SCM body of knowledge in a sustainable way into the future.
