Abstract

Purpose

The present research integrates conservation of resources theory (COR) and adaptation theory to investigate the dynamics of entrepreneurs' reactions to obstacles. Furthermore, this research explores whether entrepreneurs' effort allocations following an obstacle influence how entrepreneurs appraise subsequent loss-related events. Finally, this research seeks to understand why some entrepreneurs handle obstacles better than others by considering the role of optimism.

Design/methodology/approach

This research utilized a longitudinal survey with 130 nascent entrepreneurs across 4 time periods. This research used a multivariate latent change analysis model to examine the temporal dynamics of new venture effort after exposure to obstacles.

Findings

The results indicated that entrepreneurial obstacles at time t were associated with decreased effort in new ventures at time t+1. Furthermore, new venture effort at time t was associated with decreased effort in new ventures at time t+1. The results also demonstrated that the allocation of greater effort may lead to a decrease in subsequent obstacle appraisals, a relationship that also varies as a function of nascent entrepreneurs' optimism.

Originality/value

This research extends the understanding of the dynamic pattern of reactions following exposure to entrepreneurial obstacles. The findings suggest that, rather than being straightforward, reactions are likely to ebb and flow over time.

Abstract

It was a rough crossing and the last thing we wished to be reminded of was food. The word had an almost repulsive sound. The stomach, however, is a long‐suffering organ. The cruel writhings of its muscle layers, at loggerheads with each other, gradually ceased and the organ returned to its pre‐crossing quiescence.

Abstract

This study investigates the usefulness of net value added in explaining stock returns of a sample of US firms. The results provide evidence that current and past levels of net value added or current and past levels of changes in net value added are associated with stock returns. A case may be made for the disclosure of value added information by US firms.

Abstract

This paper is an initial attempt to discuss the American institutionalist movement as it changed and developed after 1945. Institutionalism in the inter-war period was a relatively coherent movement held together by a set of general methodological, theoretical, and ideological commitments (Rutherford, 2011). Although institutionalism always had its critics, it came under increased attack in the 1940s, and faced challenges from Keynesian economics, a revived neoclassicism, econometrics, and from new methodological approaches derived from various versions of positivism. The institutionalist response to these criticisms, and particularly the criticism that institutionalism “lacked theory,” is to be found in a variety of attempts to redefine institutionalism in new theoretical or methodological terms. Perhaps the most important of these is to be found in Clarence Ayres’ The Theory of Economic Progress (1944), although there were many others. These developments were accompanied by a significant amount of debate, disagreement, and uncertainty over future directions. Some of this is reflected in the early history of The Association for Evolutionary Economics.

Abstract

This chapter reviews literature on hazing and hazing prevention specific to university athletics, with an emphasis on US and Canadian contexts. A synthesis of studies related to the nature and extent of student-athlete hazing and gender, sexuality and hazing is shared followed by a summary of public health-based approaches to hazing prevention and athlete-specific hazing prevention strategies.

Abstract

Purpose

This study aims to enhance hygiene and structural performance in additively manufactured (AM) below-knee prosthetic sockets by optimizing ventilation and structural integrity through advanced design methodologies, including topology optimization (TO) and design for additive manufacturing (DfAM).

Design/methodology/approach

A transtibial prosthetic socket was digitally modeled from image data of the residual limb of an amputee and fabricated using acrylonitrile butadiene styrene (ABS) material using fused deposition modeling. TO and DfAM rules were applied to achieve the multi-objective design of ventilation, weight reduction and structural integrity by introducing geometric discontinuities. The level of this achievement was evaluated through finite element analysis (FEA) and mechanical testing using a novel lobe bending test.

Findings

This study found that TO significantly reduced stress concentrations and improved the strength-to-weight ratio of the socket. Mechanical testing revealed a critical failure load of 918.5 N, validated by FEA, which indicated peak stresses of 37.91 MPa. A 5 mm thick socket with circular discontinuities demonstrated enhanced ventilation and mechanical resilience.

Research limitations/implications

The focus on ABS material and specific socket designs may limit the generalizability of findings to other materials and designs.

Practical implications

The optimized socket design provides a cost-effective, high-performance solution for improving comfort and durability in below-knee prosthetic sockets within AM applications.

Originality/value

This research introduces innovative testing methods, including the lobe bending test and uses advanced optimization techniques, addressing challenges in ventilation and mechanical performance. The insights gained are valuable for future prosthetic socket design advancements.

Abstract

Purpose

Despite the continuous growth of empirical studies exploring professional learning communities (PLCs) across different education systems, little is known about PLC instruments developed and used in existing research. This article aims to capture a full picture of existing PLC instruments developed since 1990. In so doing, the authors also pay attention to the seminal work of Karen Seashore Louis in alignment with the theme of the special issue.

Design/methodology/approach

Based on the authors’ searching databases, the authors identified eleven PLC instruments and 26 applied studies using the PLC instruments since 1990. Following this, the authors closely reviewed the identified studies and their relationships (i.e. which one influences which).

Findings

The authors’ review illuminates the measurement domains, conceptual origins and methodological soundness of the existing instruments and captures the impact of Louis's work on the applied studies using PLC instruments.

Originality/value

Given that PLCs are seen as a policy measure to sustain and scale up school improvement internationally, the authors’ review provides a better understanding of what and how researchers have measured the effect of PLCs on school improvement. As the first of its kind, the authors believe that their findings can give researchers valuable ideas about how to develop and use a PLC instrument.
