Vibratory weld conditioning parameters have a great influence on the improvement of mechanical properties of weld connections. The purpose of this paper is to understand the influence of vibratory weld conditioning on the mechanical and microstructural characterization of aluminum 5052 alloy weldments. An attempt is made to understand the effect of the vibratory tungsten inert gas (TIG) welding process parameters on the hardness, ultimate tensile strength and microstructure of Al 5052-H32 alloy weldments.

Aluminum 5052 H32 specimens are welded at different combinations of vibromotor voltage inputs and time of vibrations. Voltage input is varied from 50 to 230 V at an interval of 10 V. At each voltage input to the vibromotor, there are three levels of time of vibration, i.e. 80, 90 and 100 s. The vibratory TIG-welded specimens are tested for their mechanical and microstructural properties.

The results indicate that the mechanical properties of aluminum alloy weld connections improved by increasing voltage input up to 160 V. Also, it has been observed that by increasing vibromotor voltage input beyond 160 V, mechanical properties were reduced significantly. It is also found that vibration time has less influence on the mechanical properties of weld connections. Improvement in hardness and ultimate tensile strength of vibratory welded joints is 16 and 14%, respectively, when compared without vibration, i.e. normal weld conditions. Average grain size is measured as per ASTM E 112–96. Average grain size is in the case of 0, 120, 160 and 230 is 20.709, 17.99, 16.57 and 20.8086 µm, respectively.

Novel vibratory TIG welded joints are prepared. Mechanical and micro-structural properties are tested.

By doing so, the current study contributes to careers literature by revealing the linkage between the career construction model of adaptation and career sustainability.

Jamun is an underutilised fruit crop of India whose utilization needs to be considerably increased. Despite its impressive nutritional profile and several health benefits, its cultivation is still very limited. Hence, this study aims to highlight the essential nutrients, health benefits and value-added products of jamun fruit and seed.

Major sources of bibliometric information such as Web of Science, Scopus, PubMed and Google Scholar were extensively searched with keywords such as nutritional composition of jamun, bioactive compounds, health benefits and jamun-based food products to obtain a database of 317 papers. Thirty four publications met the criteria for review.

Jamun fruit (Syzygium cumini L.) is known for its attractive colour, astringent taste, enormous nutrients and nutraceutical properties; nevertheless, this fruit is seasonal, perishable and underutilised. Furthermore, the fruit is used for the treatment of diabetes and also possess anti-cancer, anti-inflammatory, anti-obesity and cardio-protection properties. Investigations were done on the production of value-added food products such as read-to-serve beverages, jam, cookies and cake from jamun due to their several health benefits. The present review was an attempt to provide spotlights on the health benefits and food product applications of jamun fruit and its by-products.

This review systematically collates evidence from various published sources regarding the nutritional profile, development of food products from jamun and their health benefits. The compiled information will help researchers and professional become aware of the significance of jamun fruit and thereby enhances its processing and applications in food systems.

The purpose of this paper is to investigate the long-run equilibrium relationship between developed, emerging and frontier markets of the Asia-Pacific region during January 2000 to June 2016.

Zivot and Andrews’ unit root test is used to examine the existence of unit root in index series in the presence of a structural break. Gregory and Hansen’s test of cointegration is employed to examine the stable long-run relationship between the indices under study.

The results suggest that the emerging markets of China and Thailand and the frontier markets of Sri Lanka and Pakistan are fairly segmented from most of the markets in the Asia-Pacific region. Hence, these markets provide good diversification opportunities to global investors. Bidirectional cointegration analysis indicates that emerging and frontier markets influence developed markets. Hence, it can be inferred that the de facto position that only bigger markets influence small markets no longer holds true in the current environment.

The findings of this study will provide valuable inputs to global investors for creating an optimal investment portfolio.

This study does a comprehensive examination of market integration in the Asia-Pacific region. It also contributes to the thin body of work done on frontier markets. Unlike past studies, this paper analyzes the bidirectional cointegration relationship to examine if the notion that only bigger markets influence smaller markets holds true or not. Finally, this study employs advanced techniques of unit root test and cointegration test that consider structural breaks in the models.

This paper aims to gauge the quality of risk disclosure in 3,872 annual reports of Indian corporates, using a risk disclosure index (RDI) developed to capture both quality and quantity of risk disclosures.

Focussing on 69 risk items, the paper uses manual textual analysis and scores risk items using an ordinal scale, as opposed to the general practice of using a dichotomous scale.

The average risk index is low, but greater in the post-recession period than in the pre-recession period. Most disclosures are qualitative, both backward and forward-looking, and exhibit a negative tone. In addition, company age and industry sector have a significant impact on disclosure levels.

The choice and weighting of semantic qualities used to construct RDIs used in disclosure studies are inherently subjective. This exploratory study uses univariate analysis and does not explore the reasons for poor disclosure.

In addition to its usefulness for investors and companies’ management, the findings of non-compliance with certain mandatory provisions and a low average RDI is particularly relevant for policymakers and regulatory bodies.

Development of a summary measure/RDI that is novel in its differential weighting of the semantic qualities pertaining to quantification, time-orientation and tone. Further, it serves as an exploratory study about risk disclosure practices in the Indian context that reveals notable differences from findings of previous risk disclosure research. Moreover, the study examines the relationship between firms’ age and risk disclosure levels, a largely ignored aspect in disclosure research.

The purpose of this paper is to investigate the impact of mergers and acquisitions (M & A) on corporate performance. It addresses the major question related to the long-term performance of the acquiring firm.

The paper uses the long-term pre- and post-merger financial data to investigate the long-term performance. It compares performance of the acquiring firms before and after M & A. The present work conducts a comprehensive ratio analysis of 14 major ratios related to profitability, efficiency, leverage and liquidity. To ascertain the sources of the better long-term post-M & A returns, the present work decomposes the measure of operating performance into its constituents in terms of Du Pont analysis.

Taking a sample of 305 M & As during the period of January 2003 to December 2008, it has been observed that there is significant improvement in the profitability of the acquiring companies involved in M & A. The results pertaining to profitability, efficiency (in terms of utilization of fixed assets), expense and liquidity ratios show that there is an improvement in performance of the acquiring firms in the post-M & A period. The analysis in terms of Du Pont shows improvement in the long-term operating profit margin of the acquiring firms. This means higher profit is generated per unit net sales by the acquiring firms after the M & A. The higher profits (profit before interest and taxes and non-operating income) are generated primarily due to the better operating margins. The improved operating cash flows are on account of the improvement in the post-M & A operating margins of the acquirers, not due to the efficient utilization of the assets turnover to generate higher sales.

The paper contributes to the existing literature by comparing operating performance and profitability of acquirers before and after M & A using a comprehensive set of 14 ratios for a substantially large sample.

The purpose of this paper is to study the effect of corporate social responsibility (CSR) effectiveness on job seekers’ organizational attractiveness (JSA). Deriving inspiration from Carroll’s theory, the study specifically tries to measure the impact of CSR on JSA with the four dimensions pertaining to economics (PECO), pertaining to legal compliance (PLCO), pertaining to ethics (PETH) and pertaining to philanthropic (PPH). Furthermore, the paper also tries to examine the moderating role of company selection (COM SEL) done based on high or low CSR reputation and JSA.

Management and engineering students enrolled in premier institutions and universities of Western Odisha in India are surveyed for their perceptions of CSR and JSA. Purposive and convenience sampling are applied to collect data from 456 job seekers. Based on the analysis, the study proposes two main models (Models 1 and 2) wherein Model 1 tries to measure the effect of CSR on JSA and Model 2 checks the moderating effect of COM SEL on CSR and JSA. In addition, robustness of the study is tested using control variables (Models 3 and 4). Data is treated through SmartPLS 3.3 software. The structural equation modelling (partial least squares-SEM) method is applied to test the hypotheses and for further analysis.

The result reveals an interesting insight. There is a positive and significant effect of PECO, PLCO and PPH on JSA. Moreover, no such significant effect is observed between PETH and JSA. Further, the findings are contrary with respect to COM SEL, that partially moderates the effect of CSR on JSA. However, the results reveal that COM SEL has a substantial moderating effect on the PPH dimension of CSR and JSA.

The results highlight that CSR positively and significantly affects JSA in terms of PECO, PLCO and PPH, thereby emphasizing that organizations must be more focused on these perspectives of CSR. Further, though the results did not exhibit any significance with PETH, it is essential that organizations should strengthen the ethical aspects of CSR as well and align them with the CSR strategic actions. The study also confirms the moderating effect of COM SEL on PPH dimension of CSR and JSA, thereby supporting the philanthropic approach in this domain. Further, the organizations should foresee the philanthropic factor of CSR as a competitive advantage to attract potential job seekers.

This research attempts to contribute to CSR and HR literature in two ways. First, it is the first attempt to use PLS-SEM with an attempt to understand job seekers’ perception of CSR and JSA with Indian data consisting of students belonging to premier business management and engineering institutes. Second, the study is an attempt to empirically measure the moderating effect of COM SEL on JSA. To sum up, the study will provide insights to organizations to help craft CSR strategies for attracting more job seekers.

It was December 13, 2010. The Government of Uttar Pradesh announced their plan to urbanize the entire area along the Yamuna Expressway (YE) in order to prevent haphazard growth of urban sprawls on the flanks of the YE. The YE was conceived in 1997 as a dream project of Ms Mayawati, the then Chief Minister of Uttar Pradesh, with the idea of reducing the travel time between Delhi (and the larger National Capital Region) and Agra. It was a 165 km long expressway and was proposed to run from Greater Noida to Agra via Mathura. Amidst issues concerning land acquisition, and various protests and litigations, the deadline for completion of the project had extended beyond its original completion date of February 8, 2010 to April 2013. Meanwhile, the project cost had escalated from Rs 2500 crore (cr) in the year 2000 to about Rs 10,000 cr as of December 2010. By then, about 80% work on the expressway had been completed. The project was finally expected to be completed around April 2011. This was, however, subject to the pending court judgements and mitigation of risks as perceived by Jaypee Infratech, the concessionaire of the project.

The purpose of this paper is to identify the challenges surrounding the implementation of digital technology (DT) agri-food supply chain (AFSC) and explore how these challenges relate to the various sustainability dimensions. Additionally, it aims to assess how these challenges are interconnected in relation to achieving sustainable development goals (SDGs).

The study employs a mixed-method approach utilizing the EFA-ISM-Fuzzy DEMATEL technique. To support and validate the findings, exploratory factor analysis (EFA) categorized 12 critical challenges in sustainable dimensions from 141 participants' responses. Furthermore, interpretive structural modeling (ISM) and decision-making trial and evaluation (DEMATEL) methods were used to obtain the interrelationship and hierarchical structure of the challenges.

The study identified 12 critical challenges while adopting DT in AFSC. These challenges were categorized into four sustainable dimensions: technological, economic, environmental and social. These challenges hinder the achievement of SDGs as well. Lack of regulatory and policy framework with security and privacy issues were the key challenges faced while adopting DT. These observations emphasize the necessity for government and policymakers to prioritize tackling the identified challenges to successfully endorse and execute DT initiatives in AFSC while also fulfilling the SDGs.

The implication underscores the need for collaboration among various stakeholders, such as governments, policymakers, businesses and researchers. By collectively addressing these challenges, DT can be leveraged optimally, fostering sustainable practices and making progress toward achieving the SDGs within the AFSC.

The study uses a combination technique of EFA and ISM-DEMATEL to identify the challenges faced in Indian AFSC while adopting DT and categorizes the interrelation between the challenges along with fulfilling the SDGs.
