The purpose of this paper is to explore how cohesive/diverse networks affect entrepreneurial activities. In particular, an interest is shown in how cohesion and diversity may affect entrepreneurial outcomes like survival, profitability, innovation and efficiency.

The paper organizes the literature and presents conclusions about the effects of cohesion and diversity using three stages of entrepreneurial activity: opportunity development, technology and organizational creation, and exchange.

At the opportunity stage, strong ties with entrepreneurs increase the likelihood of becoming one, but are associated with lower levels of innovation. Diverse ties increase self‐efficacy and innovation. At the technology and organizational creation stage, most entrepreneurial teams are homogeneous whereas team diversity is associated with better organizational outcomes. Using strong ties to recruit potential employees provides price and commitment advantages, but may interfere with efficiency. At the exchange stage, entrepreneurs must strike a balance between weak (market based) and stronger (embedded) ties to gain preferential access to resources and customers, while maintaining diverse sources for information and market opportunities. Overall, cohesion through strong ties provides entrepreneurs with hard to find resources very early in the development of new ventures, but those resources are limited in scope and have a high cost. By contrast, diversity is more common and more important later in a venture's life cycle.

Guidelines are suggested regarding the best networking strategies at the different stages and in different instrumental areas, offering an overall evaluation of the evidence in the cohesion v. diversity debate. Directions for future research on the effects of networks on entrepreneurial outcomes are also provided.

The case opens with Martha Stewart's 2005 release from prison following her conviction for obstructing an insider-trading investigation of her 2001 sale of personal stock. The scandal dealt a crippling blow to the powerful Martha Stewart brand and drove results at her namesake company, Martha Stewart Living Omnimedia (MSO), deep into the red. But as owner of more than 90 percent of MSO's voting shares, Stewart continued to control the company throughout the scandal.

The company faced significant external challenges, including changing consumer preferences and mounting competition in all of its markets. Ad rates were under pressure as advertisers began fragmenting spending across multiple platforms, including the Internet and social media, where MSO was weak. New competitors were luring readers from MSO's flagship publication, Martha Stewart Living. And in its second biggest business, merchandising, retailing juggernauts such as Walmart and Target were crushing MSO's most important sales channel, Kmart. Internal challenges loomed even larger, with numerous failures of governance while the company attempted a turnaround.

This case can be used to teach either corporate governance or turnarounds.

Students will learn:

• How control of shareholder voting rights by a founding executive can undermine corporate governance

• The importance of independent directors and board committees

• How company bylaws affect corporate governance

• How to recognize and respond to early signs of stagnation

• How to avoid management actions that can make a crisis worse

• How weaknesses in executive leadership can push a company into crisis and foster a culture that actively prevents strategic revitalization

For decades, the Altiplano farmers of Bolivia had been marginalized by the remoteness of their home and exploitation by the private sector and injustices inflicted by the government. The notion that this impoverished region could sustain economic development might correctly have been described as hopeless. The Altiplano farmers’ inability to develop a sustainable source of income threatened their very cultural identity. The only manner in which the farmers’ culture might be sustained was through charitable donations from international NGOs. But it is exactly in this situation, when obstacles are stacked against success, where appreciative intelligence can provide an avenue to overcome despair. After years of working with NGOs, Javier Hurtado was able to identify a source of value that could provide hope and a path to sustainable development for the Altiplano farmers. This is the story of the impact that one individual's application of appreciative intelligence can have on a community. The Irupana story illustrates how our destinies are shaped by our ability to discover that which is best within ourselves and the communities in which we live. This is the story of Javier Hurtado and Martha Cordero, founders of Irupana Organic Foods located in the Bolivian Altiplano, as they discover the unique potential in the harsh Bolivian landscape and the impoverished peasant farmers that inhabit this setting. Through the framework of appreciative intelligence, the researchers observed the entrepreneurs reframe their circumstances around the positive potential that is within the Altiplano-farming community and its unique natural resources, and create a successful organic foods company.

A safe environment is critical for adolescents’ well-being. The purpose of this photovoice study is to explore reasons that make adolescents feel safe in their community.

This study was conducted in Florida through both online and in-person recruitment. After a training session on the ethical and technical use of cameras and a brief introduction of the photovoice methodology, six adolescents took photos (n = 66) in their community and discussed their photos guided by the revised SHOWeD framework. Abridged transcripts were used to match photos with corresponding discussions. Thematic analysis was conducted by the research team.

This study identified four main themes related to adolescents’ safe perceptions, including community protective factors (n = 22 photos) such as safe physical environments and community cohesion; family protective factors (n = 14 photos) including safe home and caring parents; traffic safety (n = 14 photos), such as proper road signs, seat belts for car safety and helmets and locks for bicycle safety; and public safety (n = 8 photos), such as emergency numbers, fire departments and police cars and officers.

Due to the limited number of participants, this study did not compare the similarities and differences of safety perceptions between adolescents living in high crime areas (urban communities) and those in low crime areas (suburban and rural communities). Future photovoice studies are recommended to further explore the influential factors associated with adolescents’ perceived community safety in urban and rural areas with different levels of crime rates to provide more evidence on targeted strategies for community safety promotion in each area.

By exploring the reasons for adolescents’ safe feelings in their community using photovoice, this study provides insights for future intervention programs to promote community safety for children and adolescents from the community, family, traffic and societal perspectives.

This photovoice study not only empowers adolescents to identify community assets related to their safe perceptions but also illustrates valuable insights for researchers and public health professionals for safety promotion.

This study has used a broad research question to explore the reasons that make adolescents feel safe, providing them the opportunities to express their opinions by photo taking and photo discussions. Moreover, rich information at the community, family and societal levels has been collected as related to factors contributing to adolescents’ safe perceptions, adding to the literature on community safety. In addition, this photovoice study has offered both in-person and online participation. Such combination not only provides adolescents with an opportunity to choose a participation method that works best for them but also adds to the photovoice methodology by extending the data collection from in-person to online.

Acts of interpersonal influence are observed throughout organizations, and most typically, in direct supervisor–subordinate relationships. However, researchers have focused less on subordinates bypassing the chain of command and targeting their supervisor's supervisor with influence attempts. We conceptualize a new term, “leapfrogging,” as subordinates' attempts to influence and manage the impressions of their supervisor's supervisor. Here we focus on influencing the target's perception of likability (the focus of ingratiation) and competence (the focus of self-promotion). This study focuses on its personal and situational antecedents.

Given the central role of social exchange and psychological processes within this phenomenon, we build on a social exchange and a social cognition approach. Using a sample of 131 university support personnel service employees, hierarchical regression is used to test the hypotheses.

The following antecedents of leapfrogging are hypothesized and tested: the subordinate personal characteristics of Machiavellianism, need for achievement, and fear of negative evaluation, and the situational/relational characteristic of leader–member exchange (LMX). Of these potential antecedents, subordinate Machiavellianism and LMX were the strongest predictors, and subordinates' need for achievement and fear of negative evaluation were moderate predictors.

Leapfrogging occurs when actors are frustrated with their current situation and desire change. However, influence tactics aimed at a subordinate's supervisor's supervisor may further strain a low-quality leader–subordinate relationship. As actors become increasingly dissatisfied and leave, this may result in increased organizational costs related to the loss of experienced employees and the hiring and training of new ones.

Most upward influence research has largely ignored subordinate influence attempts that go outside of the normal chain of command and target their boss's boss. The present study addresses this gap in the literature by examining leapfrog behaviors. Although acknowledged in a limited manner as a legitimate organizational behavior, this topic has received virtually no empirical attention.

This case introduces a framework for cost modeling. Two data sets (one for injection-molded plastic parts and another for compressors) allow students to apply the cost-driver framework in conjunction with basic spreadsheet and regression analyses. Although obviously applicable in a course on supply chain management, the case can also be used to teach competitive cost analysis for strategic decision making.

This paper examines how intentional mathematics coaching practices can develop teacher professional noticing of “ambitious teaching practices” (NCTM, 2020) through connected, collaborative coaching cycles.

Narrative analysis is used to examine observations of a mathematics coach and novice teacher to better understand the role of the coach in helping teachers attend to ambitious mathematics teaching (AMT) practices.

The initial findings of this study suggest that intentional use of focused goals, iterative coaching cycles and a gradual release model of coaching can support shifts in noticing of AMT from being led by the coach to being facilitated by the teacher.

This study offers new insights into the functions of mathematics coaching that can foster shifts in teacher noticing and practice toward AMT. It contributes to the literature on what mathematics coaching looks and sounds like in the context of conversations with teachers, as well as the potential influence that structured, intentional, ongoing coaching supports can have on teacher noticing.

The purpose of this paper is to develop a model of competitiveness for the bovine livestock industry in the state of Yucatan, Mexico, by considering factors such as innovation, marketing, and finance (Perea and Rivas, 2008).

Owners of 30 cattle ranches were included in the state surveys, with each ranch having at least 1,000 head of cattle. The study was quantitative, and used the method of thresholds (Pengfei, 2006), stratification of Dalenius and Hodges (1959), Pearson’s correlation, and multivariate regression analysis.

The level of competitiveness in the livestock industry in Yucatan, and a model for its determination obtained as results reflect a similar importance for the three factors, with marketing and innovation being considered relatively more important.

It is worth nothing the context in which this information can be applies.

This study is unique because the results obtained have important practical implications for the sector. The livestock industry in Yucatan represents one of the main strategic activities of the state, and now faces serious problems of competitiveness.

Although there have been many articles and books on street vendors, ambulant and fixed, around the world, and many works written about them in Mexico, little has been done on the ubiquitous ambulant beach vendors in tourist centers.

This paper offers an analysis of the backgrounds, levels of contentment, and aspirations of 25 women beach vendors interviewed in Acapulco in 2010.

A third of the women beach vendors had fathers who were peasants, and others had grandparents who were. Thus the article shows light on the fate of some of the offspring of a dispossessed peasantry. Far more than half of the women vendors were very content with their self-employment vending wares on the beach, a few because they could set their own hours, and a few because they had no boss. Other’s contentment was linked to the fact that they could help support their children. Part of this help meant keeping them in school. This was true whether the women were married, widowed, or abandoned. Not all were content, however, and this underscores the importance of their income to their households. Most of the women, though not all, had aspirations for more education and better work, whether in the formal or the informal economy.

The women can be seen as marginalized because of their current poverty, and many because of past poverty leading to a lack of educational opportunities when they were young. They value education for their children.

This article aims to explore the concept of chain value of the public port system in Ecuador from the perspective of importing/exporting companies, analyzing how perceived value in the use of port services affects customer satisfaction and the intermediate links of the influence of trust and commitment on customer loyalty.

Relying on a survey of 634 Ecuadorian companies with experience in international trade as port users and a theoretical framework well-established in the literature on consumer behavior, the empirical study found evidence of a positive and significant relationship with the knowledge of chain effects.

The findings confirm the chain effect and reveal ways to maintain an ongoing satisfactory, trust and committed relationship with users, thereby ultimately gaining and maintaining their loyalty. The conclusions suggest how this postulate can help to close the gap referred to the effective management of port services, and point out that port managers should be concerned with a continuous in-depth understanding of the perceived value and its chain effects.

The authors add evidence of the use of the postulate of the chain of effects on these dimensions, whose applicability is very well established, tested and consensual for the doctrine in industrial marketing. In contrast, it is scarcely present in the port relationship with its users.
