Abstract

Examines two modern industrial vision systems which cover both 2‐D and 3‐D applications. Describes the 2‐D Object Recognition and Inspection System [ORIS] which is based on the analysis of the gradients of grey‐scale images and used for such tasks as robotized depalletizing. Goes on to describe a 3‐D position measurement system, Car Body Position Measurement System [CAPMES] which is based on the recognition algorithms of ORIS. Covers calibration, recognition and measurement. CAPMES is used typically for complex tasks such as assembly, spray painting and sealing of car bodies. Concludes that both systems have been installed in a number of industrial applications in the automotive industry.

Abstract

Purpose

The purpose of this paper is to investigate the morphological and metallurgical changes of laser gas‐assisted nitriding of titanium implants.

Design/methodology/approach

Laser gas‐assisted nitriding of titanium implant is carried out and the metallurgical as well as the morphological changes in the nitride layer are examined using optical microscopy, SEM, XRD, and X‐ray photoelectron spectroscopy. Temperature and thermal stress fields are computed during the laser heating process adopting the finite element method. The residual stress formed in the nitride layer is measured using the XRD technique while micro‐indentation tests are carried out to determine the fracture toughness of the surface after the laser treatment process.

Findings

It is found that nitride depth layer extends to 40 μm below the surface and it is free from the cracks and micro‐voids. The residual stress formed on the surface region is higher than at some depth below the surface in the nitride layer, provided that the maximum residual stress is less than the elastic limit of the substrate material.

Originality/value

The paper contains original findings and the findings are not submitted any other journal for publication.

Abstract

Purpose

In this paper, the authors introduce supply disruption ambiguity as the inability of a sourcing firm to attach probability point estimates to the occurrence of and to the magnitude of loss from supply disruptions. The authors drew on the “ambiguity in decision-making” literature to define this concept formally, connected it to relevant supply disruption information deficit, positioned it relative to supply chain risk assessment and hypothesized and tested its negative associations with both supply base ties and inventory turnover.

Design/methodology/approach

The authors analysed survey data from 171 North American manufacturers and archival data for a subset (88 publicly listed) of these manufacturers via Ordinary Least Squares (OLS) estimation after ensuring that methodological concerns with survey research have been addressed. They used appropriate controls and employed the heteroskedasticity-based instrumental variable (HBIV) approach to ensure that inferences from our results are not unduly influenced by endogeneity.

Findings

Strong supply base ties decrease supply disruption ambiguity, which, in turn, increases inventory turnover. Moreover, strong supply base ties and data integration with the supply base have indirect and positive effects on inventory turnover. As sourcing firms strengthen ties and integrate data exchange with their supply base, their inventory turnover improves from access to information relevant to detect and diagnose supply disruptions effectively.

Originality/value

Research on supply disruption management has paid more attention to the “disruption recovery” stage than to the “disruption discovery” stage. In this paper, the authors add novel insights regarding the recognition and diagnosis aspects of the “disruption discovery” stage. These novel insights reveal how and why sourcing firms reduce their overall ambiguity associated with detecting and assessing losses from supply disruptions through establishing strong ties with their supply base and how and why reducing such ambiguity improves inventory turnover performance.

Abstract

Project networks are an increasingly salient organisational temporary form to deal with complex problems. It remains unclear, however, whether and how project networks adapt over time, and hence implement changes, both within the span of the specific project, and across projects. The authors apply the performance feedback (PF) perspective to explore how adaptive responses to PF are organised and absorbed within project networks. The authors investigate these matters in the area of humanitarian and development aid efforts, which represent complex social issues. In this context, project networks involve a multitude of actors at different distances from the implementation field, ranging from the donor, through an international Non-Governmental Organisation (NGO), to the NGO’s country offices, local NGOs and the beneficiary communities. This study’s qualitative findings, which the authors generate through an abductive analytical process, highlight that project networks dealing with complex social issues face six paradoxes based on work by DeFillippi and Sydow: the distance, difference, identity, learning, temporal and performance paradoxes. Collective goal setting, adaptive monitoring and evaluation practices, and continuous re-negotiation of aspiration levels emerge as coping mechanisms enabling project networks to internalise insights from the field and translate them into adaptive behavioural responses, mainly at the intra-project level. The authors contribute to a better understanding of adaption in these temporary forms, and particularly in its behavioural consequences. The study also advances knowledge on the PF perspective, through its application in temporary settings, on the level of the project network and in the context of complex social issues, where organisational arrangements strive to pursue multiple interdependent goals.

Abstract

The aim of the study was to evaluate depressive symptomatology within the student population of the University of Palermo (Italy). An anonymous online questionnaire was provided to the students of the University of Palermo. The first section investigated demographic and social data, while in the second section the QIDSSR16 (Quick Inventory of Depressive Symptomatology Self-Report) test was administered. 539 students (68.3% female) gave informed consent and completed the questionnaire. Considering as a dependent variable: Depressive symptomatology moderate-severe-very severe, the statistically significant independent variables associated are I don't live with my family (aOR 1.63, 95% CI 1.01-2.63, P=0.043), I currently smoke (aOR 1.55, 95% CI 1.01-2.39, P=0.048) and Low perceived health status (aOR 4.14, 95% CI 2.73-6.28, P<0.001). Smoking is associated with an increased risk of developing a high-grade depressive symptomatology. Family plays a crucial role in decreasing the risk of moderate, severe or very severe symptoms.

Abstract

Introduction: Financial failure is a concept that may arise from many internal and external factors such as operational, financial, and economic items and may incur serious losses. Over-indebtedness arising from managerial misjudgments may cause high financial distress, insufficiency, and bankruptcy. In this regard, determination of effects of capital structure decisions on financial failure risk is crucial.

Aim: The main purpose of this study is to explore the relationship between capital structure decisions and financial failure risk. For this purpose, data from Borsa İstanbul (BIST) for listed food and beverage companies for the period from 2004 to 2019 is used. Another purpose of this study is to compare the financial failure models considering capital structure theories.

Method: In the study, capital structure decisions are associated with five different financial ratios; while the financial failure risk is proxied by financial failure scores of Altman (1968), Springate (1978), Ohlson (1980), Taffler (1983), and Zmijewski (1984). Therefore, five different panel data models are used for testing these hypotheses.

Findings: The results of panel data analysis reveal that capital structure decisions have statistically significant effects on financial failure risk for all models; however, those effects vary from one financial failure model to another. Also, the results show that in the models in which financial failure risk is proxied by the Altman (1968) and Taffler (1983) scores, the aggressive financial policies increase the financial failure risk. However, regarding the models in which financial failure risk is proxied by the Springate (1978), Ohlson (1980), and Zmijewski (1984) scores, aggressive financial policies decrease the financial failure risk.

Originality of the Study: To the best of our knowledge, this chapter is original and important in terms of revealing the effects of capital structure decisions on the financial failure risk and comparing the financial failure models.

Implications: The results revealed that the risk of financial failure models represented by Altman (1968) and Taffler (1983) scores are found to be statistically stronger and more successful in meeting theoretical expectations compared to other models. Therefore, it would be more appropriate to refer Altman’s (1968) and Taffler’s (1983) financial failure models in financial failure risk measurements.

Abstract

Purpose

Conceptual and empirical research over the past 20 years has moved the social media (SM) literature beyond the embryotic stage to a well-developed academic discipline. As the lead article in the special issue in the Journal of Research in Interactive Marketing on Cutting-Edge Research in Social Media and Interactive Marketing, this review and agenda article has two key goals: (1) to review key SM and interactive marketing research over the past three years and (2) to identify the next wave of high priority challenges and research opportunities.

Design/methodology/approach

Given the “cutting-edge” research focus of the special issue, this review and research agenda paper focused on articles published in 25 key marketing journals between January 2021 and March 2024. Initially, the search request was for articles with “social media, social selling, social commerce” located in the article title, author-selected key words and journal-selected keywords. Later, we conducted searches based on terminology from articles presented in the final review. In total, over 1,000 articles were reviewed across the 25 journals, plus additional ones that were cited in those journals that were not on the initial list.

Findings

Our review uncovered eight key content areas: (1) data sources, methodology and scale development; (2) emergent SM technologies; (3) artificial intelligence; (4) virtual reality; (5) sales and sales management; (6) consumer welfare; (7) influencer marketing; and (8) social commerce. Table I provides a summer of key articles and research findings for each of the content areas.

Originality/value

As a literature review and research agenda article, this paper is one of the most extensive to date on SM marketing, and particularly with regard to emergent research over the past three years. Recommendations for future research are integrated through the paper and summarized in Figure 2.

Social implications

Consumer welfare is one of the eight emergent content areas uncovered in the literature review. Specific focus is on SM privacy, misinformation, mental health and misbehavior.
