Abstract

Purpose

Top-seat angle connection is known as one of the usual uncomplicated beam-to-column joints used in steel structures. This article investigates the fire performance of welded top-seat angle connections.

Design/methodology/approach

A finite element (FE) model, including nonlinear contact interactions, high-temperature properties of steel, and material and geometric nonlinearities was created for accomplishing the fire performance analysis. The FE model was verified by comparing its simulation results with test data. Using the verified model, 24 steel-framed top-seat angle connection assemblies are modeled. Parametric studies were performed employing the verified FE model to study the influence of critical factors on the performance of steel beams and their welded angle joints.

Findings

The results obtained from the parametric studies illustrate that decreasing the gap size and the top angle size and increasing the top angles thickness affect fire behavior of top-seat angle joints and decrease the beam deflection by about 16% at temperatures beyond 570 °C. Also, the fire-resistance rating of the beam with seat angle stiffener increases about 15%, compared to those with and without the web stiffener. The failure of the beam happens when the deflections become more than span/30 at temperatures beyond 576 °C. Results also show that load type, load ratio and axial stiffness levels significantly control the fire performance of the beam with top-seat angle connections in semi-rigid steel frames.

Originality/value

Development of design methodologies for these joints and connected beam in fire conditions is delayed by current building codes due to the lack of adequate understanding of fire behavior of steel beams with welded top-seat angle connections.

Abstract

Purpose

The COVID-19 pandemic has brought dramatic life changes to consumers. From the perspective of fashion shopping, this study aims to provide an understanding of how consumers have coped with the pandemic to maintain their physical and mental well-being.

Design/methodology/approach

Utilizing an observational research method, this study extracted and analyzed text data from Twitter, focusing on fashion consumption-related tweets posted by consumers in May 2020. Content analysis was employed to reveal consumers' coping strategies during the pandemic.

Findings

Through fashion shopping, consumers have employed various strategies to cope with the problems incurred during the pandemic as well as the associated emotional stress. Specifically, problem-focused strategies included both active coping and restraint coping. Emotion-focused strategies included positive reinterpretation, acceptance, mental disengagement and seeking social support.

Originality/value

Theoretically, this study provides empirical evidence for the Coping Orientation to Problems Experienced (COPE) Inventory in the context of using fashion shopping as a venue to cope with a pandemic. Managerial implications are also provided for the fashion industry as well as human service providers to better prepare for future public health crises.

This study aims to integrate the theory of planned behavior (TPB) and the value-belief-norm (VBN) theory into a meta-analytic framework to synthesize green consumption literature.

Abstract

Purpose

This study aims to integrate the theory of planned behavior (TPB) and the value-belief-norm (VBN) theory into a meta-analytic framework to synthesize green consumption literature.

Design/methodology/approach

By integrating the findings from 173 studies, a meta-analysis was performed adopting several analytical methods: bivariate analysis, moderation analysis and path analysis.

Findings

VBN- and TPB-based psychological factors (adverse consequences, ascribed responsibility, personal norms, subjective norms, attitude and perceived behavioral control) mediate the effects of altruistic, biospheric and egoistic values on green purchase intention. Further, inconsistencies in the proposed relationships are due to cultural factors (i.e. individualism-collectivism, power distance, uncertainty avoidance, masculinity–femininity, short- vs long-term orientation and indulgence-restraint) and countries’ human development status.

Research limitations/implications

The authors selected papers published in English; hence, other relevant papers in this domain published in other languages might have been missed.

Practical implications

The findings are useful to marketers of green offerings in designing strategies, i.e. specific messages, targeting different customers based on countries’ cultural score and human development index, to harvest positive customer responses.

Originality/value

This study is the pioneering attempt to synthesize the TPB- and VBN-based quantitative literature on green consumer behavior to resolve the reported inconsistent findings.

Abstract

In 1979, Galbraith wrote a manuscript titled “The Social Consequences of Inflation and Unemployment and Their Remedies.” The manuscript was found in the John Kenneth Galbraith Personal Papers at the John F. Kennedy Library. The reasons for Galbraith to write the article might appear at first glance to be purely contextual. At the macroeconomic level, the United States was experiencing stagflation, a situation unseen since 1945, resulting in double-digit inflation rates and high unemployment. A policy debate was going on about the Phillips curve and whether there is a trade-off between inflation and unemployment. Milton Friedman challenged the Keynesian analyses of the Phillips curve in the mid-1960s (Friedman, 1977). Galbraith’s 16-page draft manuscript provides us an incisive summary of Galbraith’s views about the causes of stagflation and what can be done about it. He provides us with an alternative to the neoclassical synthesis of Samuelson and Solow and the neoliberal thinking of Milton Friedman and F.A. Hayek.

Abstract

Today, as we hurtle towards imminent planetary destruction in the age of the Anthropocene, we believe it may be instructive to try and understand if the ancient science of spirituality can prove useful in humankind's ability to change course, even at this late hour. We argue that such a paradigm shift is critically essential for human survival and that without the inner transformation proposed by this science, it may prove impossible to build a society based on the principles of liberty, equality and fraternity. This chapter draws from foundational texts and authoritative sources across multiple religious traditions, based upon which it outlines a brief sketch of the ancient science of spirituality. We begin with an account of the differentia specifica of this science, where we delve into what kind of science this is. Since it is centrally concerned with inner transformation, we briefly outline the theory of change embedded in this science and the kind of rejuvenation it enables, which makes it possible for us to clearly perceive the key elements and the structure of reality. We then spell out the impact this has on the nature of human action, continually teasing out implications for policy and practice in our time. We provide a few concrete illustrations of the same. Inter alia, we also show how many of these insights can be found even within modern scientific and philosophical traditions, thereby indicating possibilities of convergence and synthesis between ancient and modern science, following thereby the guidance of genuine spirituality.

Abstract

Purpose

To understand the seismic behavior of reinforced concrete (RC) beams confined by corroded stirrups, low-reversed cyclic loading tests were carried out on seven RC beam specimens with different stirrup corrosion levels and stirrup ratios to investigate their mechanical characteristics.

Design/methodology/approach

The failure mode, hysteresis behavior, skeleton curves, ductility, stiffness degradation and energy dissipation behavior of RC specimens are compared and discussed. The experimental results showed that the restraint of concrete provided by corroded stirrups is reduced, which leads to a decline in seismic performance.

Findings

For the specimens with the same ratios of stirrup, as the corrosion level increased, the load-carrying capacity, stiffness, plastic deformation capacity and energy-dissipation capacity dropped significantly. Compared with the uncorroded specimen, the failure modes of specimens with high corrosion level changed from ductile bending failure to brittle failure. For the specimens with the same levels of corrosion, the higher the stirrup ratio was, the stronger the restraint effect of the stirrups on the concrete, and the seismic behavior of the specimens was obviously improved.

Originality/value

In this paper, a total of seven full-size RC beam specimens at joints with different stirrup corrosion levels and stirrup ratios were designed and constructed to explore the influences of corrosion levels and stirrup ratios of stirrups on the seismic performances. The failure modes, strain of reinforcement, hysteretic curves, skeleton curves, stiffness degradation and ductility factor of RC specimens are compared and discussed.

Abstract

Purpose

Interorganizational power dependence has become an increasingly important factor for small and medium-sized enterprises (SMEs) to improve product innovation. This paper examines the role of power dependence in SMEs' product innovation trade-offs between exploration and exploitation. The article further studies the mediating effect of supply chain adaptability and the moderating effect of knowledge acquisition on the relationship between power dependence and product innovation.

Design/methodology/approach

The study proposes a model to verify the impact of power dependence on SMEs' product innovation trade-offs based on social network theory. Two conceptually independent constructs, “availability of alternatives (ALTRN)” and “restraint in the use of power (RSPTW),” are used to evaluate the power dependence. The model also analyzed how these effects are mediated by supply chain adaptability and moderated by knowledge acquisition. The authors test these relationships using data collected from 224 SMEs in China.

Findings

The empirical analysis shows that ALTRN has a more substantial effect on exploration for product innovation, while RSTPW has a more significant impact on exploitation for product innovation. Moreover, empirical data indicate a partial mediating effect by supply chain adaptability between power dependence and product innovation of SMEs. The results also show that knowledge acquisition positively moderates the relationship between ALTRN/RSTPW, supply chain adaptability and product innovation.

Originality/value

Overall, the findings of the study advance the understanding of the roles of power dependence in product innovation for SMEs. In addition, the research also uncovers the impact mechanisms of existing theoretical frameworks and extends the boundaries of the theory.

Abstract

Purpose

This study aims to evaluate the impact of varying cultural dimensions, according to Hofstede, on corporate social responsibility (CSR) performance before and during the COVID-19 crisis.

Design/methodology/approach

This study examines the moderating impact of Hofstede’s cultural dimensions on the relationship between CSR and firm performance. The database comprises 36,295 firm-year observations from 2,135 firms operating in civil law countries.

Findings

The findings confirm that CSR investments have a positive impact on firm performance both before and after the COVID-19 crisis. Furthermore, it becomes evident that cultural dimensions play a moderating role in the CSR–firm performance relationship. The crisis has generated a shift in perspective, emphasizing the advantages of CSR in terms of reputation and financial well-being in the post-crisis environment.

Originality/value

The significance of this study lies in its examination of the relationship between CSR and firm performance within the framework of Hofstede’s cultural dimension theory, before and during the COVID-19 crisis.

Abstract

Purpose

The institutional conditions of primary care provision remain understudied in low- and middle-income countries. This study analyzes how primary care doctors cope with medical uncertainty in municipal clinics in urban India. As street-level bureaucrats, the municipal doctors occupy two roles simultaneously: medical professional and state agent. They operate under conditions that characterize health systems in low-resource contexts globally: inadequate state investment, weak regulation and low societal trust. The study investigates how, in these conditions, the doctors respond to clinical risk, specifically related to noncommunicable diseases (NCDs).

Design/methodology/approach

The analysis draws on year-long ethnographic fieldwork in Pune (2013–14), a city of three million, including 30 semi-structured interviews with municipal doctors.

Findings

Interpreting their municipal mandate to exclude NCDs and reasoning their medical expertise as insufficient to treat NCDs, the doctors routinely referred NCD cases. They expressed concerns about violence from patients, negative media attention and unsupportive municipal authorities should anything go wrong clinically.

Originality/value

The study contextualizes street-level service-delivery in weak institutional conditions. Whereas street-level workers may commonly standardize practices to reduce workload, here the doctors routinized NCD care to avoid the sociopolitical consequences of clinical uncertainty. Modalities of the welfare state and medical care in India – manifest in weak municipal capacity and healthcare regulation – appear to compel restraint in service-delivery. The analysis highlights how norms and social relations may shape primary care provision and quality.
