Small-bore drains (≤ 16 Fr) are used in many centers to manage all pleural effusions. The goal of this study was to determine the proportion of avoidable chest drains and associated complications when a strategy of routine chest drain insertion is in place.

We retrospectively reviewed consecutive pleural procedures performed in the Radiology Department of the McGill University Health Centre over one year (August 2015–July 2016). Drain insertion was the default drainage strategy. An interdisciplinary workgroup established criteria for drain insertion, namely: pneumothorax, pleural infection (confirmed/highly suspected), massive effusion (more than 2/3 of hemithorax with severe dyspnea /hypoxemia), effusions in ventilated patients and hemothorax. Drains inserted without any of these criteria were deemed potentially avoidable.

A total of 288 procedures performed in 205 patients were reviewed: 249 (86.5%) drain insertions and 39 (13.5%) thoracenteses. Out of 249 chest drains, 113 (45.4%) were placed in the absence of drain insertion criteria and were deemed potentially avoidable. Of those, 33.6% were inserted for malignant effusions (without subsequent pleurodesis) and 34.5% for transudative effusions (median drainage duration of 2 and 4 days, respectively). Major complications were seen in 21.5% of all procedures. Pneumothorax requiring intervention (2.1%), bleeding (0.7%) and organ puncture or drain misplacement (2%) only occurred with drain insertion. Narcotics were prescribed more frequently following drain insertion vs. thoracentesis (27.1% vs. 9.1%, p = 0.03).

Routine use of chest drains for pleural effusions leads to avoidable drain insertions in a large proportion of cases and causes unnecessary harms.

The author presents new estimates of the probability weighting functions found in rank-dependent theories of choice under risk. These estimates are unusual in two senses. First, they are free of functional form assumptions about both utility and weighting functions, and they are entirely based on binary discrete choices and not on matching or valuation tasks, though they depend on assumptions concerning the nature of probabilistic choice under risk. Second, estimated weighting functions contradict widely held priors of an inverse-s shape with fixed point well in the interior of the (0,1) interval: Instead the author usually finds populations dominated by “optimists” who uniformly overweight best outcomes in risky options. The choice pairs used here mostly do not provoke similarity-based simplifications. In a third experiment, the author shows that the presence of choice pairs that provoke similarity-based computational shortcuts does indeed flatten estimated probability weighting functions.

This study aims to verify whether the reduction factors for the post-fire performance of Grade 10.9 bolts stated in an earlier study at the TU Darmstadt are also valid for shear and combined tension and shear.

Tests on Grade 10.9 bolt sets under combined tension and shear were carried out. The tested bolts were heated and cooled without being stressed by an additional mechanical load before being tested.

The test results show that the reduction factors can also be adopted for bolts under combined tension and shear, but the tension-shear-ratio has an influence on the load bearing capacity.

The post-fire performance of high-strength bolts is of special interest when a building structure is evaluated after an event of fire. In contrast to conventional structural steel, high-strength bolts do not recover their original strength and material properties.

The COVID-19 pandemic and its related economic meltdown and social unrest severely challenged most countries, their societies, economies, organizations, and individual citizens. Focusing on both more and less successful country-specific initiatives to fight the pandemic and its multitude of related consequences, this chapter explores implications for leadership and effective action at the individual, organizational, and societal levels. As international management scholars and consultants, the authors document actions taken and their wide-ranging consequences in a diverse set of countries, including countries that have been more or less successful in fighting the pandemic, are geographically larger and smaller, are located in each region of the world, are economically advanced and economically developing, and that chose unique strategies versus strategies more similar to those of their neighbors. Cultural influences on leadership, strategy, and outcomes are described for 19 countries. Informed by a cross-cultural lens, the authors explore such urgent questions as: What is most important for leaders, scholars, and organizations to learn from critical, life-threatening, society-encompassing crises and grand challenges? How do leaders build and maintain trust? What types of communication are most effective at various stages of a crisis? How can we accelerate learning processes globally? How does cultural resilience emerge within rapidly changing environments of fear, shifting cultural norms, and profound challenges to core identity and meaning? This chapter invites readers and authors alike to learn from each other and to begin to discover novel and more successful approaches to tackling grand challenges. It is not definitive; we are all still learning.

While brand purpose has gained traction in academia and industry, it overlaps with other socially-oriented branding concepts, generating confusion and criticism around what brand purpose is and how it should be implemented. This study aims to clarify conceptualisations of brand purpose and related concepts, developing a managerial framework for effective implementation and contributing a future research agenda for scholars.

The paper presents the results of a systematic literature review on brand purpose, exploring the current knowledge. A total of 202 studies from 75 journals were drawn from a wide range of databases and met the identified criteria relevant to brand purpose, published up to and including 2023. Full papers were empirically analysed using qualitative iterative thematic analysis to identify common and emerging themes and synthesise this into a framework.

Beyond identifying the diverse applications of brand purpose, the BEING framework is proposed. This acronym captures five principles of brand purpose: beyond profit, enduring commitment, integrated values, nurturing stakeholders and genuine action.

The BEING framework provides clear managerial guidance for implementing brand purpose, urging brand leaders to enact meaningful brand purpose and champion purpose within organisations.

As more brands pursue a higher purpose, this research elucidates the meaning of brand purpose and offers an actionable framework for brands to contribute to a better world.

This work examines the related branding concepts, clarifying the brand purpose concept and offering the BEING framework to articulate essential components of effective brand purpose.

Social relationships play an important role in organizational entrepreneurship. They are crucial to entrepreneurs’ decisions because, despite the bleeding-edge technological advancements observed nowadays, entrepreneurs as human beings will always strive to be social. During the COVID-19 pandemic many companies moved activities into the virtual world and as a result offline Social relationships became rarer, but as it turns out, even more valuable, likewise, the inter-organizational cooperation enabling many companies to survive.

This chapter aims to develop knowledge about entrepreneurs’ SR and their links with inter-organizational cooperation. The results of an integrative systematic literature review show that the concept of Social relationships, although often investigated, lacks a clear definition, conceptualization, and operationalization. This chapter revealed a great diversity of definitions for Social relationships, including different scopes of meaning and levels of analysis. The authors identify 10 building blocks and nine sources of entrepreneurs’ Social relationships. The authors offer an original typology of Social relationships using 12 criteria. Interestingly, with regard to building blocks, besides those frequently considered such as trust, reciprocity and commitment, the authors also point to others more rarely and narrowly discussed, such as gratitude, satisfaction and affection. Similarly, the authors discuss the varied scope of sources, including workplace, family/friendship, past relationships, and ethnic or religious bonds. The findings of this study point to a variety of links between Social relationships and inter-organizational cooperation, including their positive and negative influences on one another. These links appear to be extremely dynamic, bi-directional and highly complex.

Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.

In this chapter, we explore how our backgrounds as mixed-heritage Latinas influence our work as junior faculty members at a four-year public Hispanic-serving institution (HSI). Drawing on the conceptual lens of intersectionality, we address the question: how do our multiple social identities affect our identity development and socialization as faculty members?

As part of a critical mass of junior Latina scholars studying educational issues pertinent to the Latina community, we build a sense of community in what can be an isolated environment for women faculty of color. Using our own examples, we examine how two faculty members who might be considered “outsiders within” the Latina/o community draw on their Latinidad as a source of strength to employ their academic work in advancing social justice for Latina/os. Our identities have influenced us to take into account multiple social categories and social contexts in the study of educational phenomena. Serving as faculty within the institutional context of an HSI has distinctively influenced our socialization as new faculty.

We believe that this examination has implications for understanding how people can build cross-cultural collaborations and identify productively with communities that may not necessarily recognize them as “authentic.” Our exploration also offers insights for building a more inclusive academy, particularly for junior scholars from historically underrepresented backgrounds. Based on the themes identified in this research, we draw recommendations for university personnel interested in the recruitment and retention of Latina junior faculty. More broadly, this research has implications for developing support systems for faculty members who have been historically underrepresented in their fields and those who study marginalized populations.

Researchers, subject specialists, and information professionals have long been aware of scientific and technical (sci‐tech) dictionaries available from the U.S. government. Yet these reference sources often remain invisible to the general public, especially in libraries that exclude government documents from the main catalog or that maintain separate documents collections. However, as more libraries automate their holdings and load cataloging records for government publications into their online public access catalogs (OPACs), government documents should become more visible. Until then, it may surprise some to learn that many U.S. government agencies have allocated vast resources into compiling, publishing, and updating technical dictionaries in print, microfiche, and electronic format.

Recently, there has been an increase in the number and type of studies in the organizational sciences that examine curvilinear relationships. These studies are important because some relationships have context-specific inflection points that alter their magnitude and/or direction. Although some scholars have utilized basic techniques to make meta-analytic inferences about curvilinear effects with the limited information available about them, there is still a tremendous opportunity to advance our knowledge by utilizing rigorous techniques to meta-analytically examine curvilinear effects. In a recent study, we used a novel meta-analytic approach in an effort to comprehensively examine curvilinear relationships between destructive leadership and followers' workplace outcomes. The purpose of this chapter is to provide an actionable guide for conducting curvilinear meta-analyses by describing the meta-analytic techniques we used in our recent study. Our contributions include a detailed guide for conducting curvilinear meta-analyses, the useful context we provide to facilitate its implementation, and our identification of opportunities for scholars to leverage our technique in future studies to generate nuanced knowledge that can advance their fields.
