Laggards or Leaders: Conservers of Traditional Agricultural Knowledge in Bolivia

Many sustainable agricultural practices are based on local and traditional farming knowledge. This article examines the conservation and loss of three traditional practices in the Bolivian Altiplano that agronomic research has shown increase the resiliency of small farmers in the face of climate‐related risks. These practices are the use of manure, the use of local forecasts and risk‐management strategies, and the preservation of crop biodiversity. Although these practices are widely used today, farmers have been steadily abandoning them during the past decade. This article examines the characteristics of those who maintain and those who abandon traditional practices to see if the abandonment of local knowledge can be explained by the adoption‐diffusion literature. This research does not support the adoption‐diffusion literature; although the factors related to conservation are slightly different for each practice, the findings do not support the idea that young, educated, and wealthier farmers are more likely to reject local knowledge. Instead, off‐farm activities such as migration, employment, and trade seem to be related to the decline in local practices as each affects the availability of labor and the availability of people to learn these practices.     

Reliability and validity of the French version of the 18-item Karasek job content questionnaire

Previous studies have shown that job strain, a combination of high psychological demands and low decision latitude, may be involved in the development of cardiovascular diseases and other health outcomes. In 1985, Karasek recommended a standard questionnaire to measure psychological demands (nine items) and job decision latitude (nine items). The internal consistency, factorial validity, discriminant validity, and 1-year stability of the French version of this instrument were evaluated in a population of 8263 white collar workers. Participants filled out the questionnaire during working hours in the context of a larger cardiovascular study. A subgroup of the study population completed the questionnaire again 1 year later (n = 953). Internal consistency was adequate: .74 for men and .73 for women for psychological demands and .83 for men and .81 for women for decision latitude. The results of the factor analysis were consistent with the two dimensions expected from the theory, although some items had high loading on two factors. Variations in the means of psychological demand and decision latitude scores and variations in the prevalence of high job strain by gender, job category, and age support the discriminant validity. These results were generally comparable to those observed with the English version. The percentages of workers remaining, after 1 year, in the same category of psychological demands, decision latitude, and job strain were 86.6, 86.1 and 75.2% respectively. These data provide evidence of the reliability and validity of the French version of these psychological demand and decision latitude scales     

Les métiers flous du développement rural

Along with the notion of development, new jobs have emerged characterized by: a vague, overall definition; an ambiguity as to roles (especially in dealings with locally elected officials); makeshift statuses; and occupational itineraries that cannot be reduced to civil service careers. As this examination of their work over three decades shows, the autonomy of rural development agents has been related to a “phase of invention”, when the switch was made from rural planning to development. Role ambiguity still prevails and has even spread, owing to the social conditions of employment, to occupational itineraries. Given the cofinancing of public authorities’ “territorial actions”, we see a couple forming between elected officials, who want to take hold in an intercommunal territory, and development agents, who “create their jobs” by capturing subsidies. Over this 30-year period, a peculiar image of “fuzzy jobs” has emerged.     

Active aging and pension reform: The gender implications in France

In the first section of this article, the authors Christel Gilles and Antoine Parent, argue that in France, public policy and the pension system provide financial incentives favoring early retirement. The implementation of “bridge jobs” to facilitate the transition from full employment to full retirement, could, in theory, lessen the long-term decline in employment rates of men and women. Gilles and Parent, in the second section, question the idea that rising labor force participation rates among women are adequate to narrow pension inequalities between men and women. Regarding this point, we also note that since women's careers are generally shorter than men's and their labor income remains, on average, lower, an increase, in female labor force participation would lead, in an occupational-based system, to a substitution effect between direct and indirect entitlements. The impact of this effect on pension gender inequalities remains uncertain. In the third section, the authors examine, from a gender perspective, other pension reform options that may, in theory, provide greater gender equality, but that are, in practice, far from the implementation phase.     

The Development of Parent–Child Relationship Perceptions in Boys from Childhood to Adolescence: A Comparison Between Disruptive and Non-Disruptive Boys

The absence or weakness of the father role is considered by many authors as one of the principal explaining factors of disruptive behavior and other psychopathologies among children. However, empirical studies on the specific role of the father are rare. Boys with stable disruptive behavior from age 5 until age 15 were compared to boys who have never been disruptive during the same time period. The perceptions that boys have regarding their relationships with their fathers from childhood to adolescence was compared to, perceptions concerning their relationships with their mothers. The results indicate that boys from both groups generally feel less loved and less appreciated by their fathers than by their mothers in adolescence but not in childhood. The boys perceived that their two parents love and appreciate them a lot less at age 15, than at age 9 and age 11. They felt less loved and appreciated by their fathers than their mothers. At age 15, disruptive boys considered they were less loved by their two parents than non-disruptive boys did. The differences in the perceptions by the boys concerning the quality of relationships with their parents appear during adolescence.     

Cooperation among competitors as status-seeking behavior: Network ties and status differentiation

Status-based affiliation represents a valuable resource in economic exchange. However, affiliation strategies introduce a status ordering paradox: whereas higher status actors seek to maintain status hierarchies, lower status actors strive to affiliate with more prestigious actors. In this paper, using original data on the network of social and professional ties among 72 hotel managers clustered in an Italian hotel district, we develop a theory of status-seeking behavior that involves the exchange of status for valued resources.     

The management of firms’ alliance network positioning: Implications for innovation

In spite of the frequent calls for a much more integrated approach, the field of management still faces the ever continuing challenges in attempting to bridge the gap between academic research and managerial actions and practices. The field of strategic alliances and firms’ networks are those among which research and practice are more diverging. Trying to cover this separation, the article presents an empirical research on automotive industry that investigates the effects on innovation performance of the position that firms occupy in the network of alliances. The hypothesis that guides this research is that innovation is generated not only from the resources that a company is able to develop internally, but also through access to resources and capabilities owned by the external companies and organizations that the firm itself is tied to through alliances and cooperation agreements. Beyond this broad argument, the paper links tightly research and practice showing way and how the quality of access to resources owned by partners is influenced by the position occupied in the network of alliances and not only by the existence of single collaborative ties. Assuming a managerial approach which relies on the milestones of network research, different types of positioning in the network of alliances are discussed and tested on their impact on innovation.     

Comparing professional identities, attitudes, and views in public communication: A study of Chilean journalists and public relations practitioners

Public relations (PR) practitioners’ and journalists’ professional views and attitudes toward each other have been a subject of academic inquiry during the past decades; however, much of this research has focused on Europe and North America. In other regions of the world, for example in Latin America, historical developments and social understandings have led to slightly different conceptualizations of PR and journalism. Using Chile as a case study, this paper reports the results of an examination of Chilean journalists’ and PR practitioners’ professional conceptions. While both groups tend to have somewhat similar views of media relations and see themselves as part of the same profession, there are also important differences which are most likely based on professional socialization processes rather than educational backgrounds or sociodemographic and work related variables. Implications for contextually grounded approaches to the study of PR and journalism are highlighted.     

Post hoc false positive control for structured hypotheses

In a high-dimensional multiple testing framework, we present new confidence bounds on the false positives contained in subsets S of selected null hypotheses. These bounds are post hoc in the sense that the coverage probability holds simultaneously over all S, possibly chosen depending on the data. This article focuses on the common case of structured null hypotheses, for example, along a tree, a hierarchy, or geometrically (spatially or temporally). Following recent advances in post hoc inference, we build confidence bounds for some prespecified forest-structured subsets and deduce a bound for any subset S by interpolation. The proposed bounds are shown to improve substantially previous ones when the signal is locally structured. Our findings are supported both by theoretical results and numerical experiments. Moreover, our bounds can be obtained by an algorithm (with complexity bilinear in the sizes of the reference hierarchy and of the selected subset) that is implemented in the open-source R package sansSouci available from https://github.com/pneuvial/sanssouci , making our approach operational.
