ABSTRACTA Joint Task Force comprised of members of the Association for Lesbian, Gay, Bisexual, and Transgender Issues in Counseling (ALGBTIC) and the Association for Assessment and Research in Counseling (AARC) present standards of care for assessment of Lesbian, Gay, Bisexual, Transgender, Gender Expansive, and Queer/Questioning (LGBTGEQ+) Persons. 相似文献

ABSTRACTA framework for approaching lesbian, gay, bisexual, transgender, queer+ (LGBTQ+) youth is presented that honors their voice. This methodology utilizes participant-driven photo elicitation as a qualitative data collection method, and then integrates thematic analysis. A brief review of current literature is provided to outline gaps, which establish the need to expand effective research methods with LGBTQ+ youth. Photo elicitation is explained with discussion specific to use with LGBTQ+ youth. Thematic analysis is identified and explained as an analytic approach. Challenges of implementing this methodology are discussed with attention to ethical concerns. 相似文献

Li et al. (2011) presented the novel idea of using support vector machines (SVMs) to perform sufficient dimension reduction. In this work, we investigate the potential improvement in recovering the dimension reduction subspace when one changes the SVM algorithm to treat imbalance based on several proposals in the machine learning literature. We find out that in most situations, treating the imbalanced nature of the slices will help improve the estimation. Our results are verified through simulation and real data applications. 相似文献

Given a configuration of pebbles on the vertices of a connected graph G, a pebbling move removes two pebbles from some vertex and places one pebble on an adjacent vertex. The pebbling number of a graph G is the smallest integer k such that for each vertex v and each configuration of k pebbles on G there is a sequence of pebbling moves that places at least one pebble on v. First, we improve on results of Hurlbert, who introduced a linear optimization technique for graph pebbling. In particular, we use a different set of weight functions, based on graphs more general than trees. We apply this new idea to some graphs from Hurlbert’s paper to give improved bounds on their pebbling numbers. Second, we investigate the structure of Class 0 graphs with few edges. We show that every n-vertex Class 0 graph has at least \(\frac{5}{3}n - \frac{11}{3}\) edges. This disproves a conjecture of Blasiak et al. For diameter 2 graphs, we strengthen this lower bound to \(2n - 5\), which is best possible. Further, we characterize the graphs where the bound holds with equality and extend the argument to obtain an identical bound for diameter 2 graphs with no cut-vertex. 相似文献

ABSTRACTWriting is a skill that spans many competencies. The Council on Social Work’s Educational Policy and Accreditation Standards promotes a holistic view of competence informed by knowledge, values, skills, and cognitive and affective processes. This teaching note contributes to the scholarship of teaching and learning by describing a professional writing course that uses a holistic pedagogical approach. We provide pragmatic strategies and assignments that can be readily adapted by other faculty and programs. 相似文献

Soil-atmosphere exchange of carbon dioxide,methane and nitrous oxide in urban garden systems: impact of irrigation,fertiliser and mulch 总被引:1,自引:1,他引:0

Urban green spaces provide important ecosystem services, such as amenity, biodiversity, productivity, climate amelioration,
hydrological and biogeochemical cycling. Intensively managed urban gardens can sequester carbon through vegetation growth
and soil C increase, but may experience nitrous oxide (N2O) emissions and reduced soil methane (CH4) uptake from irrigation and fertiliser use. Soil atmosphere exchange of N2O, CH4 and carbon dioxide (CO2) was measured in lawn and wood chip mulched garden areas in Melbourne, Australia in winter, spring and summer under various
water and fertiliser regimes. Gas exchange before and after lawn fertiliser application was measured continuously for three
weeks using an automated chamber system. Applying fertiliser led to a peak N2O emission of >60 μg N m−2 h−1, but overall only weekly irrigation (10 mm) significantly increased mean soil N2O emissions above that in other treatments. Under mulch, mean soil N2O emissions (14.0 μg N m−2 h−1) were significantly smaller than from irrigated lawn (27.9 μg N m−2 h−1), whereas mean soil CH4 uptake under mulch (−30.7 μg C m−2 h−1) was significantly greater (p < 0.01) than in any lawn treatment. Lawns were either a weak CH4 sink or source. Soil C density (0–25 cm) under mulch (12.5 kg C m−2) was greater that under lawn (8.0 kg C m−2). On a carbon dioxide equivalent (CO2-e) basis, soil N2O emissions offset the benefits of soil CH4 uptake. Mulched garden areas provide greatest C sequestration potential in soil and vegetation and the smallest non-CO2 emissions, as soil CH4 uptake offsets a large fraction of soil N2O emissions. Results of this study suggest that reducing the irrigation and fertiliser application to lawns can help mitigate
GHG emissions from urban garden systems, and increasing the area of mulched perennial garden beds can also provide net GHG
benefits; however, this needs to be tested in other garden systems with different soil types and environmental conditions. 相似文献

This study integrates the results of quantitative and qualitative methods to elucidate the association between sexual identity and physical and sexual abuse among Puerto Rican drug users. A structured questionnaire was administered to 800 subjects in New York and 399 in Puerto Rico. A total of 93 subjects (7.9%) self-identified as homosexual or bisexual. Gay males were significantly more likely than heterosexual males to report first occurrence of physical abuse by a family member in childhood. Both gay and bisexual males were more likely than their heterosexual counterparts to report first experiencing unwanted sex in childhood and intimate partner physical abuse later in life. Lesbians were more likely than female heterosexuals to report unwanted sex in childhood. Qualitative data were collected through in-depth life histories with 21 subjects and suggest that gay and lesbian subjects perceive antihomosexual prejudice on the part of family members as one cause of childhood physical and sexual abuse. 相似文献

Equality is related to relationship success, yet few couples achieve it. In this qualitative study, we examine how couples with children in two time cohorts (1982 and 2001) moved toward equality. The analysis identifies three types of couples: Postgender, gender legacy, and traditional. Movement toward equality is facilitated by: (a) Stimulus for change, including awareness of gender, commitment to family and work, and situational pressures; and (b) patterns that promote change, including active negotiation, challenges to gender entitlement, development of new competencies, and mutual attention to relationship and family tasks. Implications for practice are discussed. 相似文献

1. Clenched fist syndrome is a clinical entity in which no organic disease can be found. 2. The syndrome usually follows a minor inciting incident and is associated with swelling, pain, and paradoxical stiffness. 3. Patients with severe forms of clenched fist syndrome may experience infections of the palm or joints. 相似文献

This article provides evidence to the debateabout whether or not investments designated forcompliance with environmental performance andtechnology standards favor or harm the workproductivity of companies. A panel data modelis analyzed, which panel refers to 53 largeSpanish companies quoted on the stock exchangeand that have participated in a subsidizedenvironmental protection program during the1990–1995 period, specifically in theIndustrial and Technological Program for theEnvironment (PITMA). A Cobb-Douglas productionfunction is used to relate the workproductivity to a measure of the pollutionabatement investment dedicated to compliancewith standards. The resulting negativecoefficient, although close to zero, should notbe interpreted as a result derived from justany kind of regulation, but rather a result ofthe kind of regulation analyzed in this work,meaning the command and control regulation thatoften binds companies to make environmentalinvestments that are not productive in theconventional economic sense, although they areproductive in terms of environmental quality.In addition, and in order to specify the kindof company to which the conclusions of thispaper are applicable, the characteristics ofthe companies that participated in PITMA areanalyzed comparatively with companies that didnot participate. 相似文献
