INFLUENCES ON THEf INCLUSION OF CHILDREN IN FAMILY THERAPY BRIEF REPORT

This study examined factors that influence family therapists to include children in or exclude them from therapy sessions. We hypothesized that therapist comfort, child problem type (internalizing vs. externalizing), family composition (one- vs two-parent families), and presenting problem (child-oriented problem vs. adult-oriented problem) affect therapists' inclusion of children. A survey of clinical members of AAMFT found that half of the therapists excluded children on the basis of their comfort and that those who felt more comfortable were more likely to include children in sessions. Therapists included children more frequently in cases of an internalizing vs. an externalizing child, more with single-parent than two- parent families, and more often when the presenting problem focused on a child than on an adult. Implications of the findings are discussed.     

Using housing growth to estimate habitat change: detecting Ovenbird response in a rapidly growing New England State

Numerous measures of human influence on the environment exist, but one that is of particular importance is houses as they can impact the environment from species through the landscape level. Furthermore, because the addition of houses represents an important component of landscape change, housing information could be used to assess ecological responses (e.g., decline in wildlife habitat) to that change. Recently developed housing density data represents a potential source of information to assess landscape and habitat change over long periods of time and at broad spatial extents, which is critically needed for conservation and management. Considering the potential value of housing data, our goal was to demonstrate how changes in the number of houses leads to changes in the amount of habitat across the landscape, and in-turn, how these habitat changes are likely to influence the distribution and abundance for a species of conservation concern, the Ovenbird (Seiurus aurocapillus). Using a relationship between Ovenbird abundance and housing density, we predict suitable habitat in the forests of Massachusetts (USA) from 1970 to 2030. Over this 60-year period, the number of houses was projected to increase from 1.84 to 3.32 million. This magnitude of housing growth translates into a 57 % decline in Ovenbird habitat (6,002 km² to 2,616 km²), a minimum decline of ~850,000 (48 %) Ovenbirds, and an increase in the number of subpopulations across the landscape. Overall, housing data provide important information to robustly measure landscape and habitat change, and hence predict population change of a species. We suggest that time series of housing data linked to ecological responses (e.g., Ovenbird abundance) offers a novel and underutilized approach to estimating long-term and spatially broad predictions of ecosystem response to landscape change, which in turn can inform conservation and management.     

Comments on zacks' recent paper on one-sided cusum procedures

The goal of this paper is to propose approximations for the cdf and the inverse cdf of the normal sample median. The presented methodology, which seems to not have been investigated before, suggests to fit the normal sample median distribution with a symmetrical Johnson S_U: distribution having ap-proximatively the same second and fourth moments. The results obtained with this approach, compared with the normal approximation, are very impressive, especially for the inverse cdf. One important application of the inverse cdf approximation of the normal sample median is the computation of accurate α‐level median/range control limits for any value of α (and not only for the popular value α = 0.0027). This paper can be also viewed as an homage to Professor N.L. Johnson's works by making a link between two of his major papers.     

SELF ISSUES FOR FAMILY THERAPY EDUCATORS

Family therapy educators frequently encourage self-reflection in their students and clients. However, little attention has been paid to the challanges and processes of the eudcators themselves. In this piece, four faculty members reflect individually and collectively on their lives and roles as educators. the describe family-of-origin influences, the intersections of their personal and academic lives, systemic factors in the professional setting, balancing work and family, hierarchy, gender, and coping strategies ot increase support and reduce competition. They recommend a deliberate process of self-reflection to other family therapy educators and offer suggestions for improving the organizational dynamic of family therapy training programs.     

Efficient and easy-to-use sample size formulas in ratio-based non-inferiority tests

In many biomedical applications, tests for the classical hypotheses based on the difference of treatment means in a one-way layout can be replaced by tests for ratios (or tests for relative changes). This approach is well noted for its simplicity in defining the margins, as for example in tests for non-inferiority. Here, we derive approximate and efficient sample size formulas in a multiple testing situation and then thoroughly investigate the relative performance of hypothesis testing based on the ratios of treatment means when compared with differences of means. The results will be illustrated with an example on simultaneous tests for non-inferiority.

Multicultural supervision: lessons learned about an ongoing struggle

This article examines the experiences of seven diverse therapists in a supervision course as they wrestled with the real-world application of multicultural supervision. Existing literature on multicultural supervision does not address the difficulties that arise in addressing multicultural issues in the context of the supervision relationship. The experiences of six supervisory candidates and one mentoring supervisor in addressing multicultural issues in supervision are explored. Guidelines for conversations regarding multicultural issues are provided.     

Spatial and temporal residential density patterns from 1940 to 2000 in and around the Northern Forest of the Northeastern United States

Over the past 60 years, housing growth has outpaced population growth in the United States. Conservationists are concerned about the far-reaching environmental impacts of housing development, particularly in rural areas. We use clustering analysis to examine the pattern and distribution of housing development since 1940 in and around the Northern Forest, a heavily forested region with high amenity and recreation use in the Northeastern United States. We find that both proximity to urban areas and an abundance of natural amenities are associated with housing growth at the neighborhood level in this region. In the 1970s, counterurbanization led to higher rates of growth across rural areas. The Northern Forest now has extensive interface between forest vegetation and residential development, which has the potential to profoundly alter the ecological and social benefits of these forests.     

VERTICAL RELATIONS UNDER CREDIT CONSTRAINTS

We model the impact that credit constraints and market risk have on the vertical relationships between firms in the supply chain. Firms which might face credit constraints in future investments become endogenously risk averse when accumulating pledgable assets. In the short run, the optimal supply contract involves risk sharing, so inducing double marginalization. Credit constraints thus result in higher retail prices, and this is true whether the firm is debt or equity funded. Further, we offer a new theory of supplier finance arms as we show an intrinsic complementarity between supply and lending which reduces financing inefficiencies created by informational asymmetries. The model offers: a theory of countervailing power based on credit constraints; a transmission mechanism linking the cost of borrowing with retail prices; and a motive for outsourcing supply (or distribution) in the face of market risk.
