Counseling Transgendered, Transsexual, and Gender‐Variant Clients

Abstract: The emergent consciousness and political activism within the transgender community has important implications for the field of counseling. In the current paradigm, the focus has shifted from using surgical and hormonal interventions and thereby enabling transgendered persons to “pass” within the traditional gender binary of society to affirming the unique identities of transgendered persons. To prepare counselors, counselor educators, and counseling supervisors for this important challenge, the authors describe the evolving nature of the transgender community, discuss mental health issues and counseling interventions for use with transgendered clients, and present a case study detailing the progression of counseling with 1 transgendered client.

Measurements of gross and net ecosystem productivity and water vapour exchange of a Pinus ponderosa ecosystem, and an evaluation of two generalized models

Abstract: Summary Net ecosystem productivity (NEP), net primary productivity (NPP), and water vapour exchange of a mature Pinus ponderosa forest (44°30′ N, 121°37′ W) growing in a region subject to summer drought were investigated along with canopy assimilation and respiratory fluxes. This paper describes seasonal and annual variation in these factors, and the evaluation of two generalized models of carbon and water balance (PnET-II and 3-PG) with a combination of traditional measurements of NPP, respiration and water stress, and eddy covariance measurements of above-and below-canopy CO2 and water vapour exchange. The objective was to evaluate the models using two years of traditional and eddy covariance measurements, and to use the models to help interpret the relative importance of processes controlling carbon and water vapour exchange in a water-limited pine ecosystem throughout the year. PnET-II is a monthly time-step model that is driven by nitrogen availability through foliar N concentration, and 3-PG is a monthly time-step quantum-efficiency model constrained by extreme temperatures, drought, and vapour pressure deficits. Both models require few parameters and have the potential to be applied at the watershed to regional scale. There was 2/3 less rainfall in 1997 than in 1996, providing a challenge to modelling the water balance, and consequently the carbon balance, when driving the models with the two years of climate data, sequentially. Soil fertility was not a key factor in modelling processes at this site because other environmental factors limited photosynthesis and restricted projected leaf area index to ∼1.6. Seasonally, GEP and LE were overestimated in early summer and underestimated through the rest of the year. The model predictions of annual GEP, NEP and water vapour exchange were within 1–39% of flux measurements, with greater disparity in 1997 because soil water never fully recharged. The results suggest that generalized models can provide insights to constraints on productivity on an annual basis, using a minimum of site data.

Targeting perennial vegetation in agricultural landscapes for enhancing ecosystem services

Abstract: Over the past century, agricultural landscapes worldwide have increasingly been managed for the primary purpose of producing food, while other diverse ecosystem services potentially available from these landscapes have often been undervalued and diminished. The incorporation of relatively small amounts of perennial vegetation in strategic locations within agricultural landscapes dominated by annual crops—or perennialization—creates an opportunity for enhancing the provision of a wide range of goods and services to society, such as water purification, hydrologic regulation, pollination services, control of pest and pathogen populations, diverse food and fuel products, and greater resilience to climate change and extreme disturbances, while at the same time improving the sustainability of food production. This paper synthesizesthe current scientific theoryand evidence for the role of perennial plants in balancing conservation with agricultural production, focusing on the Midwestern USA as a model system, while also drawing comparisons with other climatically diverse regions of the world. Particular emphasis is given to identifying promising opportunities for advancement and critical gaps in our knowledge related to purposefully integrating perennial vegetation into agroecosystems as a management tool for maximizing multiple benefits to society.

Conceptualizing Juvenile Prostitution as Child Maltreatment: Findings from the National Juvenile Prostitution Study:

Abstract: Two studies were conducted to identify the incidence (Study 1) and characteristics (Study 2) of juvenile prostitution cases known to law enforcement agencies in the United States. Study 1 revealed a national estimate of 1,450 arrests or detentions (95% confidence interval [CI]: 1,287-1,614) in cases involving juvenile prostitution during a 1-year period. In Study 2, exploratory data were collected from a subsample of 138 cases from police records in 2005. The cases are broadly categorized into three main types: (a) third-party exploiters, (b) solo prostitution, and (c) conventional child sexual abuse (CSA) with payment. Cases were classified into three initial categories based on police orientation toward the juvenile: (a) juveniles as victims (53%), (b) juveniles as delinquents (31%), and (c) juvenile as both victims and delinquents (16%). When examining the status of the juveniles by case type, the authors found that all the juveniles in CSA with payment cases were treated as victims, 66% in third-party exploiters cases, and 11% in solo cases. Findings indicate law enforcement responses to juvenile prostitution are influential in determining whether such youth are viewed as victims of commercial sexual exploitation or as delinquents.

Chapter 8 – Methods for the measurement of seagrass growth and production

Abstract: Direct growth measurements require fewer assumptions than those based on reconstructive techniques. When direct measurements, which require repeated visits and considerable effort, are not possible, for instance, in remote populations or in year-round assessments, reconstructive techniques are recommended. Indirect growth measurement methods involve collecting lengths of rhizome with attached stems and leaves, and reconstructing the growth interval and pattern of the plants by counting the number of leaf scars laid down on the stem or rhizome. Reconstructive analyses can also be used to derive estimates of shoot mortality and recruitment in the population. Direct assessments of seagrass growth are recommended using marking methods and the determination of the plastochrone interval, while indirect reconstructive methods are recommended for evaluation of annual growth or long-term cycles from the rhizome record. The marking technique is the choice of approach whenever repetitive visits to the meadow investigated are possible and whenever the different structures to be marked are accessible for marking purposes with tolerable disturbance. However, this is not the case for species with deep-growing rhizomes, where reconstructive techniques are useful. The reconstruction approach is of limited use for species with short life spans or annuals, for which structures older than one year are scarce or non-existent. Application of reconstruction techniques to these populations would likely render biased estimates. In these instances, leaf or rhizome marking must be repeated over time to determine annual growth.
