Religious Identity and Consumption

Consumption choices assist in solving the problem of how to convey and recognize religious identities. In the communication of an identity, individuals use the knowledge embedded in consumption norms, which restrict the range of choices to a smaller set and abbreviate the required knowledge for encoding and decoding messages. Using this knowledge as a shared framework for understanding, individuals with religious beliefs can choose consumption items that would not only strengthen their beliefs but also help them express the intensity of their commitments to these beliefs. Because individuals and societies have different beliefs, norms, commitments, and expressive needs, consumption choice can help to express these differences. Our explanation contrasts with incentive-based approaches that view religious consumption norms as solutions to free-rider problem inherent in clubs.

Teachers' Views of Human Rights Education

The Universal Declaration of Human Rights (UDHR) states that education should be "directed to the full development of the human personality and to the strengthening of respect for human rights and fundamental freedoms... promote understanding, tolerance and friendship among all nations, racial or religious groups." This study surveyed 53 teachers on their views of Human Rights Education, including their familiarity with the concept, their self-efficacy with teaching it, and conditions that would increase the likelihood of their teaching it. The study found that, regardless of familiarity with the topic, years of teaching experience, or school location (urban/suburban), most teachers were open to teaching Human Rights Education. They did identify the need for better resources in the form of lesson plans, teaching materials, and professional training. In addition, support from other teachers, administration, and parents was felt to be important in order for them to undertake Human Rights Education. The best strategy to move forward with Human Rights Education would be to provide resources and support for teachers so that we can be living up to the expectations put forth in the UDHR.

Enhanced Cold Tolerance in Transgenic Tobacco Expressing a Chloroplast Omega-3 Fatty Acid Desaturase Gene under the Control of a Cold-inducible Promoter

A new cold-inducible genetic construct was cloned using a chloroplast-specific omega-3-fatty acid desaturase gene (FAD7) under the control of a cold-inducible promoter (cor15a) from Arabidopsis thaliana. RT-PCR confirmed a marked increase in FAD7 expression, in young Nicotiana tabacum (cv. Havana) plants harboring cor15a-FAD7, after a short-term exposure to cold. When young, cold-induced tobacco seedlings were exposed to low-temperature (0.5, 2 or 3.5 degrees C) for up to 44 days, survival within independent cor15a-FAD7 transgenic lines (40.2-96%) was far superior to the wild type (6.7-10.2%). In addition, the major trienoic fatty acid species remained stable in cold-induced cor15a-FAD7 N. tabacum plants under prolonged cold storage while the levels of hexadecatrienoic acid (16:3) and octadecatrienoic acid (18:3) declined in wild type plants under the same conditions (79 and 20.7% respectively). Electron microscopy showed that chloroplast membrane ultrastructure in cor15a-FAD7 transgenic plants was unaffected by prolonged exposure to cold temperatures. In contrast, wild type plants experienced a loss of granal stacking and disorganization of the thylakoid membrane under the same conditions. Changes in membrane integrity coincided with a precipitous decline in leaf chlorophyll concentration and low survival rates in wild type plants. Cold-induced double transgenic N. alata (cv. Domino Mix) plants, harboring both the cor15a-FAD7 cold-tolerance gene and a cor15a-IPT dark-tolerance gene, exhibited dramatically higher survival rates (89-90%) than wild type plants (2%) under prolonged cold storage under dark conditions (2 degrees C for 50 days).

The Effects Of Reinforcement Inclusions On Wear Tolerance, Playing Quality And Physical Properties In A Silt Loam And Sand Rootzone Matrix

Reinforcement inclusions have been advocated to alleviate wear, compaction, and unstable surfaces in sports fields, but little research on the effects of these materials has been conducted in the USA. Experiments were established on a native silt loam and a sand rootzone matrix, seeded with a Kentucky bluegrass (Poa pratensis L.) blend, at the Joseph Troll Turf Research Center, University of Massachusetts, Amherst, USA to determine the effects of reinforcement inclusions on wear, surface hardness, traction, ball roll, ball bounce resilience, water infiltration rate, soil bulk density, air porosity, total porosity, and root weights. Three types of reinforcement inclusions (Sportgrass, Netlon, Turfgrids) were tested along with a non-reinforced control in a three year study. The treatments were set out in a randomized complete block design with four replications in both soils. No inclusion provided less wear or greater infiltration or air-filled porosity relative to the control. Reinforcement inclusions showed significant differences, however, in surface hardness, traction, and ball roll relative to the control, although this varied with the time of year. Infiltration rates, airfilled porosity, total pore space, bulk density, hardness, traction, ball roll, and ball rebound were greater on the sand rootzone than on the silt loam. Significant correlations were present between soil bulk density, surface hardness, traction, and ball roll. Based on our study, the use of reinforcement inclusions to provide better wear tolerance for sand or native soil athletic fields is not warranted. Certain playing surface characteristics, however, may be slightly improved with the use of reinforcement inclusions. The use of sands for sports surfaces is justified based upon the improvement in playing quality characteristics and soil physical properties important to a good playing surface.
