The purpose of this study is to examine the perceptions of Texas female police officers toward their colleagues. Further, the study measures respondents’ perceptions regarding work‐related stress. An independent sample t‐test analysis was conducted while controlling for the percentage of female officers working at participating Texas law enforcement agencies. Overall, the findings suggest that the percentage of female officers employed in a particular law enforcement agency did not produce a statistically significant impact on respondents’ perceptions of their male/female counterparts or stress‐related issues.

Presents results of a study which examined 50 US police officers perceptions regarding performance, applicability, effectiveness and safety issues when assigned to two‐officer units, compared with a one‐officer unit, for patrol operations in an urban setting. Half the group comprised an experimental area’s two‐officer units and half comprised a control area’s one‐officer units. It was found that officers generally agreed they would perform the same whether they were in a one‐ or two‐officer patrol car; that two‐officer units should be used at night and in areas where people mistrust the police, that two‐officer units could observe more than a single officer and respond more quickly to calls. However, most officers disagreed that two one‐officer cars could accomplish twice as much as one two‐officer car and that officers are more likely to be injured in two‐officer cars then in one‐officer cars. Notes the possibility of distractions, misunderstandings or disagreements taking place between partners sharing a vehicle for eight hours, as well as intrusion of privacy into an officer’s role/duty as a police officer.

This study aims to develop a highly loaded filament with spherical metallic particles for fused filament fabrication (FFF) technology. The research focuses on optimizing powder loading, printing parameters and final processes, including debinding and sintering, to produce successful metal parts.

The optimal powder loading was identified by measuring mixing torque and viscosity at various temperatures. The filament was extruded, and printing parameters − particularly printing speed to ensure proper material flow − were optimized. Different filling patterns were also examined. After printing, the polymeric binder was removed and the parts were sintered to form the final metal components.

The optimal powder loading was determined to be 55 vol.%. The best surface quality was achieved with an optimized printing speed of 5 mm/s. Parts printed with various infill patterns were studied for differences in open, closed and total porosity, showing a strong link between porosity and infill pattern.

This comprehensive study provides new insights into manufacturing metal parts using FFF technology. It fills a gap in the literature regarding feedstock viscosity and shear rate in highly loaded metal filaments during FFF. Additionally, it uniquely examines the open, closed and total porosity of metal parts printed with different infill patterns.

In this paper, I explore what shapes the identities of digital nomads (DNs), a class of remote workers who travel and work concurrently. Through extensive fieldwork and interviews with 50 digital nomads conducted in seven coworking hostels in Mexico in 2022, I construct a theory of DN identity. I base this upon the frequent transformations they undergo in their Circumstances, which regularly change their worker identity.

DNs relinquish traditional social determinants of identity, such as nationality and religion. They define their personal identities by their passions and interests, which are influenced by the people they meet. DNs exist in inherently transitive social spaces and, without rigid social roles to fulfil, they represent themselves authentically. They form close relationships with other long-term travellers to combat loneliness and homesickness. Digital nomads define their worker identities around their location independence. This study shows that DNs value their nomadic lifestyle above promotions and financial gain. They define themselves by productivity and professionalism to ensure the sustainability of their lifestyle. Furthermore, digital nomad coworking hubs serve focused, individual work, leaving workplace politics and strict ‘office image’ norms behind. Without fixed social and professional roles to play, digital nomads define themselves personally according to their ever-evolving passions and the sustainability of their nomadic life. Based on these findings, I present a cyclical framework for DN identity evolution which demonstrates how relational, logistical, and socio-personal flux evolves DN’s worker identities.

The present study examines head of state gender and national collectivism to explain how some leaders have been able to manage a pandemic better than others.

We measure pandemic deaths per million using objective numbers for each country. Country collectivism is measured using the GLOBE study. Qualitative analyses of world leader speeches are used to examine how health-focused leaders’ language is. Media attention with sentiment analysis about each leader’s handling of the pandemic is also used to show how others reacted to leaders.

Countries with female leaders showed fewer pandemic deaths than those led by male leaders. The interaction between leader gender and country collectivism predicted death. Media sentiment was more favorable for women leaders than men leaders.

During times of crises, women’s more careful tendencies keep their constituents safer than their male counterparts. Country collectivism also aids male leaders in keeping constituents safe.

The present study helps unpack when women leaders thrive and outperform their male counterparts. This furthers United Nations Sustainable Development Goal 5: gender equality.

The study examines leader gender and national collectivism to predict pandemic deaths.

The growing displacement of theory and other forms of wide-ranging knowledge of social phenomena by empirical research methods in economics is widely noted by economists and historians of economic knowledge. Less attention has been devoted, however, to understand the materialization of such changes in the scientific practices. This article studies the recent transformations in the epistemological practices at CEDE, a research center in Colombia. I use a machine learning technique called Topic Modeling, interviews to CEDE researchers, and exegesis of papers to characterize a shift in the production of knowledge in microeconometrics at CEDE during the years 2000 and 2018. I explain this shift by characterizing two sets of epistemological practices that implies a recent tendency to disdain research that cannot make a “strong” causal inference.

The aim of this study is to explore and understand corporate governance patterns in family firms across Latin America. This is in response to several calls in the academic literature urging for more empirical studies in corporate governance in developing regions.

Following a configurative perspective, a hierarchical cluster analysis is applied to a sample of the 155 largest Latin American family firms.

The authors identify three main corporate governance configurations across Latin American countries. First, the exported governance model resembles many characteristics of Anglo-American and Continental Europe governance patterns of public listed control, having independence from the board of directors, and mainly hiring non-family management. Second, the super-familial governance model describes private ownership where one or multiple families control both the board of directors and the top-management team. Finally, the hybrid governance model is the largest cluster identified in the sample and combines governance characteristics of both of the foregoing configurations. This configuration exhibits ownership structured through public offerings of shares combined with leadership of the board of directors by a family member as well as moderate family influence on the board and management.

This is the first study to investigate corporate governance in the largest listed and privately-owned family firms in Latin America. The article extends the conversation on family firm heterogeneity and contributes to the configurative approach in the family business field by offering a cross-country perspective and identifying meaningful taxonomies that are applicable beyond national boundaries.

Construction projects usually suffer delays, and the causes of these delays and its cost overruns have been widely discussed, the weather being one of the most recurrent. The purpose of this paper is to analyze the influence of climate on standard construction work activities through a case study.

By studying the extent at which some weather variables impede outdoor work from being effectively executed, new maps and tables for planning for delays are presented. In addition, a real case regarding the construction of several bridges in southern Chile is analyzed.

Few studies have thoroughly addressed the influences of major climatic agents on the most common outdoor construction activities. The method detailed here provides a first approximation for construction planners to assess to what extent construction productivity will be influenced by the climate.

Although this study was performed in Chile, the simplified method proposed is entirely transferable to any other country, however, other weather or combinations of weather variables could be needed in other environments or countries.

The implications will help reducing the negative social, economic and environmental outcomes that usually emerge from project delays.

Climatic data were processed using extremely simple calculations to create a series of quantitative maps and tables that would be useful for any construction planner to decide the best moment of the year to start a project and, if possible, where to build it.

This study aims to understand the leadership characteristics of founders of social and environmental enterprises in Latin America who have achieved business success with a focus on sustainability despite difficult social, economic, political and even health contexts in which they live.

This nonexperimental research is a qualitative, descriptive and exploratory study. Twenty-one in-depth interviews were conducted with social/environmental entrepreneurs of the Kunan Network (an organization that groups the entrepreneurial ecosystem in Peru).

The study analyzes the leadership profile and characteristics of entrepreneurs who have created profitable businesses with a social/environmental focus that solve relevant social problems and contribute to improving people’s quality of life and caring for the environment.

Although only 21 business leaders with outstanding participation and positive social and environmental impact were included in this study, they were supported and recognized by the Kunan Network.

The study contributed to the conceptualization and understanding of the profile of leaders of social and environmental enterprises, whose main challenges are to solve social or environmental problems of society and contribute to improving the quality of life of people and the environment. Knowing the profile of these entrepreneurs generates value to the knowledge of the subject and contributes to understand and propose strategies to improve the ecosystem of social-environmental entrepreneurship in emerging countries such as Peru. This will contribute to the creation of relationships and alliances with various social actors: public, private, third sector, academia, among others, for the management and promotion of sustainable business.

The purpose of this paper is to review the contributions of what has been established as Latin American thought, as science, technology, and innovation (STI) in Latin America have been strongly related to development.

The analysis method is based on the review of a group of Latin American and Latinoamericanista (Latin Americanist) authors who were selected on the basis of their contributions to the explanation and proposals of public policy related to STI. The following are some of the questions that guide the analysis. How much has STI in Latin American thought contributed to the development theory? Given the fact that there are other dominant mainstreams, can we say that Latin American thought is still relevant?

The main conclusion of this work is that Latin American thought is still applied to current Latin American development discussions. This can be proven by the creation of particular concepts and analytical frameworks such as structural heterogeneity, development styles, authentic and spurious competitiveness, Sabato’s Triangle, the centre-periphery model, and STI policy practices.

This paper gathered contributions and categorised them into three dimensions: state participation (intensity, composition), industrialisation as the impulse for development, and instruments and public policy actions that can be implemented or have already been implemented.

El propósito de este trabajo es el de reflexionar sobre algunas aportaciones provenientes de lo que hemos denominado pensamiento latinoamericano en relación con la innovación, la ciencia, la tecnología y su relación con el desarrollo.

El método de análisis se basa en la revisión de un conjunto de autores latinoamericanos y latinoamericanistas que hemos seleccionado con base en sus aportaciones para la explicación y sus propuestas de política pública en relación con la CTI. Algunas preguntas que guían nuestro análisis son las siguientes: ¿en qué medida el pensamiento latinoamericano en CTI ha contribuido a la teoría del desarrollo? y ¿dada la existencia de otros enfoques que predominan como pensamiento único, podemos hablar de una vigencia del pensamiento latinoamericano?

La principal conclusión de nuestro trabajo es que hay un pensamiento latinoamericano vigente que ha sido y aún es un referente actual para la discusión del desarrollo en la región latinoamericana, como lo muestran la creación de conceptos y esquemas analíticos como los de heterogeneidad estructural, estilos de desarrollo, la competitividad auténtica y espuria, el Triángulo de Sábato, centro-periferia, así como estrategias de política en CTI.

Como parte del marco analítico hemos agrupado al conjunto de aportaciones en tres direcciones: a) la participación del Estado (intensidad, composición); b) la industrialización como impulso al desarrollo y c) los instrumentos y medidas de política pública a implementar o que han sido implementados.
