There have been increasing calls for the United States (U.S.) government’s implementation of broad public access policies mandating free online access to federally funded research. This study examines the potential impact of such a policy on peer-reviewed forestry literature. The authors analyze information about federal government authorship, federal government funding, and U.S. authorship indicated in articles published in five core forestry journals in 2006. The results of the analysis provide evidence that federal public access legislation would have a significant impact on the accessibility of forestry literature published in leading journals in the field. 相似文献

The computer software industry is an extreme example of rapid new product introduction. However, many consumers are sophisticated enough to anticipate the availability of upgrades in the future. This creates the possibility that consumers might either postpone purchase or buy early on and never upgrade. In response, many software producers offer special upgrade pricing to old customers in order to mitigate the effects of strategic consumer behavior. We analyze the optimality of upgrade pricing by characterizing the relationship between magnitude of product improvement and the equilibrium pricing structure, particularly in the context of user upgrade costs. This upgrade cost (such as the cost of upgrading complementary hardware or drivers) is incurred by the user when she buys the new version but is not captured by the upgrade price for the software. Our approach is to formulate a game theoretic model where consumers can look ahead and anticipate prices and product qualities while the firm can offer special upgrade pricing. We classify upgrades as minor, moderate or large based on the primitive parameters. We find that at sufficiently large user costs, upgrade pricing is an effective tool for minor and large upgrades but not moderate upgrades. Thus, upgrade pricing is suboptimal for the firm for a middle range of product improvement. User upgrade costs have both direct and indirect effects on the pricing decision. The indirect effect arises because the upgrade cost is a critical factor in determining whether all old consumers would upgrade to a new product or not, and this further alters the product improvement threshold at which special upgrade pricing becomes optimal. Finally, we also analyze the impact of upgrade pricing on the total coverage of the market. 相似文献

Pathways to Prevention is a developmental prevention project focused on the transition to school in a disadvantaged multicultural urban area in Queensland. The project incorporates two elements: The Preschool Intervention Program (PIP) promotes communication and social skills related to school success; and the Family Independence Program (FIP) (parent training, facilitated playgroups, support groups, etc) promotes family capacity to foster child development. Using a quasi-experimental design (N= 597), improvements in boys' but not girls' behaviours over the preschool year were found. FIP reached more than a quarter of the target population, including many difficult-to-reach families experiencing high stress. Case studies and other qualitative data suggest positive outcomes. 相似文献

1. Water intoxication is a severe complication of disordered water balance. Hyponatremia precedes water intoxication and can be identified through abnormal diurnal weight variation. 2. The St. Louis Target Weight Procedure (STWP) is a nonintrusive method that includes a client's baseline weight, frequent weights throughout the day, a target weight of 5% above the baseline weight, and restricted fluids if the target weight is exceeded. 3. The STWP was positively related to an increase in urine concentration; thus it is successful in restoring normal fluid balance. 相似文献

POSITIVE PRACTICE IN FAMILY THERAPY 总被引:1,自引:0,他引:1
Alan Carr 《Journal of marital and family therapy》1997,23(3):271-293
Positive practice, a brief integative approach to consultation with families, is described in this paper. A clear distinction is made between the stages of planning, assessment, therapy, and disengagement. Guideliness for progression from one stage to the next are provided. Frameworks for deciding who to invite to preliminary sessions and methods for planning and organizing lines of inquiry are incorporated into this approach to practice. A three-column model is used to construct formulations. The model allows therapists and clients to map information about the pattern of interaction around the presenting problem, beliefs that constrain family members from altering their roles in these problem-maintaining patterns, and factors that have predisposed family members to hold these beliefs. Positive practice offers methods for evolving new behavioral patterns and belief systems within sessions and for arranging homework tasks for clients between sessions. It also incorporates methods for dealing with resistnace, for managing therapeutic crises, for convening indivudial sessions and borader network meetings, for disengaging from the consultation process, and for recontracting for further episodes of therapy. This evolving approach to practice draws on ideas from many traditions within the family therapy field and takes account of recent research relevent to the practice of family therapy. 相似文献

International students underuse counseling services, which are grounded in Western cultural values. The authors describe a support group for Asian international students that they launched at a large midwestern university to help students feel at ease with American university life, address homesickness, language problems, and academic and social stressors. Co-leaders created a safe and culturally sensitive atmosphere where the women could network, socialize, and address their issues. Group treatment offers many advantages over individual counseling and can enhance the health of international students. 相似文献

We evaluated the effects of multiple exemplar instruction (MEI) on the relation between listener and intraverbal categorization repertoires of six typically developing preschool-age children using a nonconcurrent multiple-probe design across participants. After failing to emit intraverbal categorization responses following listener categorization training, participants were exposed to MEI in the form of alternating response forms (listener and intraverbal) during categorization training with novel stimulus sets. For two participants for whom there was some evidence of emergent intraverbal responding, responding was variable. For the remaining four participants, 32 to 99 MEI trial blocks produced minimal improvement in responding or no emergent responding at all. The results are discussed in terms of Skinner’s analysis of verbal behavior and naming theory. 相似文献
