Connecting Societal Change to Value Differences Across Generations: Adolescents, Mothers, and Grandmothers in a Maya Community in Southern Mexico
This study tests the hypothesis that societal change from subsistence agriculture to a market economy with higher levels of formal schooling leads to an increase in individualistic values that guide human development. Values relating to adolescent development and the transition to adulthood were compared across three generations of women in 18 families in the Maya community of Zinacantán in southern Mexico. Grandmothers grew up in Zinacantán when it was a farming community; mothers grew up during the introduction of commerce in the late 1970s and 1980s; daughters are now experiencing adolescence with an opportunity to attend high school in their community. Comparisons were also conducted between 40 female and male adolescents in high school and a matched sample of 40 adolescents who discontinued school after elementary. Values were measured using eight ethnographically derived social dilemmas about adolescent relationships with parents and peers, work and family gender roles, and sexuality and partnering. One character in the dilemmas advocates for interdependent values; a second character advocates for independent values. High school adolescents were more likely to endorse characters articulating independent values than non–high school adolescents, mothers, and grandmothers. Involvement in a market economy was also associated with higher levels of independent value endorsement in the mother and grandmother generations. Results suggest that the introduction of commerce drove value changes between grandmother and mother generations, and now schooling drives change. Qualitative examples of participants’ responses also illustrate how families negotiate shifting values
Values for gender roles and relations among high school and non-high school adolescents in a Maya community in Chiapas, Mexico.
In the current study, I describe values for gender roles and cross-sex relations among adolescents growing up in a southern Mexican Maya community in which high school was introduced in 1999. A total of 80 adolescent girls and boys, half of whom were attending the new high school, provided their opinions on two ethnographically derived vignettes that depicted changes in gender roles and relations occurring in their community. Systematic coding revealed that adolescents not enrolled in high school tended to prioritise ascribed and complementary gender roles and emphasise the importance of family mediation in cross-sex relations. Adolescents who were enrolled in high school tended to prioritise equivalent and chosen gender roles, and emphasised personal responsibility and personal fulfillment in cross-sex relations. Perceptions of risks and opportunities differed by gender: girls favourably evaluated the expansion of adult female role options, but saw risks in personal negotiations of cross-sex relations; boys emphasised the loss of the female homemaker role, but favourably evaluated new opportunities for intimacy in cross-sex relations
Redescription of Hypoptopoma inexspectata (Holmberg, 1883), with notes on its anatomy (Siluriformes: Loricariidae).
Hypoptopoma inexspectata is diagnosed and redescribed based on the examination of additional
material and comparison with its congeners. This poorly known hypoptopomine species is distributed in the
Paraguay and Paraná river draĂnages. Hypoptopoma inexspectata is diagnosable based on the
autapomorphy biserial arrangement of anterior snout rostral margin odontodes, laterally extended to limit
between second and third infraorbital plates, with dorsally directed dorsad series separated from ventrally
directed ventrad series by a narrow odontode-free area, which at the level of first and second infraorbital
plates is reduced to a dividing line of the series. The species can be further distinguished by the
combination (1) low number of canal-bearing lateral plates (20-22, typically 21), (2) presence of a shield of
prepectoral dermal plates, (3) arrangement of abdominal plates in one paired series of 3-5 plates, (4)
shorter least interorbital distance 4856% head lengh, (5) larger horizontal eye diameter 17-20% head lengh,
and (6) least orbit-nare distance 812% head lengh. Intraspecific variation skull dermal bones, neuracranium
and suspensorium bones, dermal plates, adipose fin is reported. (PDF has 20 pages.
Viscous instability of a compressible round jet
The compressible linear stability equations are derived from the Navier Stokes equations in cylindrical polar coordinates. Numerical solutions for locally parallel flow are found using a direct matrix method. Discretization with compact finite difference is found to have better convergence properties than a Chebyshev spectral method for a round jet test case. The method is validated against previous results and convergence is tested for a range of jet profiles. Finally and en method is used to determine the dominant frequency of a Mach 0.9 jet

Conservation in conflict: Illegal drugs versus habitat in the Americas
About the book:
State of the Wild is a biennial series that brings together international conservation experts and writers to discuss emerging issues in the conservation of wildlife and wild places.
Each volume in the series combines evocative writings with a fascinating tour of conservation news highlights and vital statistics from around the world. One-third of each volume focuses on a topic of particular concern to conservationists working to protect wildlife and our last wild places. This 2008–2009 edition considers the integration of wildlife health, ecosystem health, human health, and the health of domestic animals—a “One World–One Health” approach to disease and conservation.
This focus is complemented with essays clustered into sections that address other key issues—conservation of species; conservation of wild places; people, culture, and conservation; and the art and practice of conservation. Essays cover a broad range of topics, from restoring biodiversity on the prairies to mapping the state of the oceans to the conservation impacts of lawlessness and coca cultivation in Colombia. Essay contributions come from people directly involved in on-the-ground conservation efforts and offer a unique and valuable perspective on often-overlooked topics.
State of the Wild’s accessible approach educates a wide range of audiences while at the same time presenting leading-edge scientific overviews of hot topics in conservation. Uniquely structured with magazine-like features up front, conservation news in the middle, and essays from eminent authors and experienced scientists throughout, this landmark series is an essential addition to any environmental bookshelf

Classical Turnpike Theory and the Economics of Forestry
Classical turnpike theory, as originally conceived by Samuelson, pertains to optimal growth theory over a large but infinite time horizon with given initial and terminal stocks. In this paper, we present two turnpike results in the context of the economics of forestry with given initial and terminal forest configurations. Our results depart from the general theory in that they pertain to a transitional production set which does not satisfy the assumptions of inaction and free disposal, and rely on a recently-discovered non-interiority assumption on concave (not necessarily differentiable) benefit functions that implies, and is implied by, the asymptotic convergence of good programs.
Education and Health: Evaluating Theories and Evidence
There is a large and persistent association between education and health. In this paper, we review what is known about this link. We first document the facts about the relationship between education and health. The education %u2018gradient%u2019 is found for both health behaviors and health status, though the former does not fully explain the latter. The effect of education increases with increasing years of education, with no evidence of a sheepskin effect. Nor are there differences between blacks and whites, or men and women. Gradients in behavior are biggest at young ages, and decline after age 50 or 60. We then consider differing reasons why education might be related to health. The obvious economic explanations %u2013 education is related to income or occupational choice %u2013 explain only a part of the education effect. We suggest that increasing levels of education lead to different thinking and decision-making patterns. The monetary value of the return to education in terms of health is perhaps half of the return to education on earnings, so policies that impact educational attainment could have a large effect on population health.
DO U.S. MARKETING ORDERS HAVE MUCH MARKET POWER? AN EXAMINATION OF THE ALMOND BOARD OF CALIFORNIA
This paper tests the conventional wisdom that U.S. marketing orders act as profit-maximizing cartels. The paper analyzes the marketing order for U.S. almonds in both the domestic and export markets. Such a case study is relevant to all U.S. marketing orders because the size and scope of the U.S. almond industry on the world market, and the legal authority of the almond marketing order makes it a likely prospect for exhibiting true cartel behavior. The authors find that the market power exerted by the Almond Board of California's reserve setting is significantly less than would be expected from a profit-maximizing cartel.Marketing,
