Survey of Irrigation Methods in California in 2001

Reliable information on irrigation methods is important for determining agricultural water demand trends. Therefore, a study was conducted during 2002 to collect information on irrigation methods that were used by growers to irrigate their crops in 2001. The results were compared to earlier surveys to assess trends in cropping and irrigation methods. A one-page questionnaire was developed to collect information on irrigated land by crop and irrigation methods. The questionnaire was mailed to 10,000 growers in California that were randomly selected from a list of 58,000 growers by the California Department of Food and Agriculture, excluding rice, dry-land, and livestock producers. From 1972 to 2002, the area planted has increased from 15 to 31% for orchards and from 6 to 16% for vineyards. The area planted to vegetables has remained relatively static, while that planted to field crops has declined from 67 to 42% of the irrigated area. The land irrigated by low-volume (drip and microsprinkler) irrigation has increased by about 33%, while the amount of land irrigated by surface methods has decreased by about 31%. Sprinkler usage has decreased in orchards and vineyards, but it has increased in vegetable crops.     

The roles of respect for parental authority and parenting practices in parent-child conflict among African American, Latino, and European American families.

In this study, the authors examined whether parent-child conflict during the middle childhood years varied among families characterized as having different cultural traditions regarding issues of respect for parental authority and parenting practices. The sample included 133 African American, European American, and Latina girls (M age = 8.41 years) and their mothers. African American and Latina girls showed significantly more respect for parental authority than did European American girls. Furthermore, African American and Latina mothers reported significantly more intense arguments when respect was low than did European American mothers. Higher levels of discipline and better communication by mothers were both associated with reports of lower frequency of conflict; ethnicity did not moderate this association. Thus, respect for authority was most salient to group differences in conflict. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Personal religious practice, risky behavior, and implementation intentions among adolescents.

The benefits of religiousness for promoting well-being and avoiding risky behaviors has long been noted, especially for adolescents, but a precise understanding of the mechanism underlying this effect on risky behaviors has not yet been developed. We hypothesized that religious practices help religious adolescents form implementation intentions (IIs) when pursuing decisions and goals to avoid risky behaviors. We predicted that participants with higher rates of private religious practice would generate greater numbers and higher quality IIs to avoid risky behaviors relative to other participants. In this preliminary exploration, 50 college students completed assessments of private religious practices, risk–benefit evaluations about risky scenarios, and the number and quality of IIs they could generate to avoid risk in those scenarios. Results supported our predictions: After controlling for age and gender, participants who engaged more frequently in private religious practice were able to generate both more and higher quality IIs about avoiding risky scenarios. This provides initial support for the hypothesis that religiousness may protect against risky behaviors by enhancing the abilities of religious adolescents to form IIs to avoid risky behaviors.

Rethinking the concept of acculturation: Implications for theory and research.

This article presents an expanded model of acculturation among international migrants and their immediate descendants. Acculturation is proposed as a multidimensional process consisting of the confluence among heritage-cultural and receiving-cultural practices, values, and identifications. The implications of this reconceptualization for the acculturation construct, as well as for its relationship to psychosocial and health outcomes, are discussed. In particular, an expanded operationalization of acculturation is needed to address the “immigrant paradox,” whereby international migrants with more exposure to the receiving cultural context report poorer mental and physical health outcomes. We discuss the role of ethnicity, cultural similarity, and discrimination in the acculturation process, offer an operational definition for context of reception, and call for studies on the role that context of reception plays in the acculturation process. The new perspective on acculturation presented in this article is intended to yield a fuller understanding of complex acculturation processes and their relationships to contextual and individual functioning.
