Commentary on Family-Directed Structural Therapy: Ten Years of Building on Family Strengths
This is an original and ground-breaking article because the authors have operationalized important concepts in family-centered thinking and practice, developed assessment tools that can be used for testing the validity of these concepts and then collected data from control and treatment groups of families in four very different service areas.
Nevertheless, the use of \u27structural family therapy\u27 in the title and design of instruments without grounding this research in the non-linear systems assumptions that are the hallmark of the literature on structural family therapy, obscures some of the theoretical and practice problems that are faced in family treatment today
Temperature, organic matter and the sustainability of aquatic systems
Changes in sustainability of aquatic ecosystems are likely to be brought about by the global warming that has been widely predicted. In this article, the effects of water temperature on water-bodies (lakes, oceans and rivers) are reviewed followed by the effects of temperature on aquatic organisms. Almost all aquatic organisms require exogenous heat before they can metabolise efficiently. An organism that is adapted to warm temperatures will have a higher rate of metabolism of food organisms and this increases feeding rate. In addition, an increase in temperature raises the metabolism of food organisms, so food quality can be altered. Where populations have a different tolerance to temperature the result is habitat partitioning. One effect of prolonged high temperature is that it causes water to evaporate readily. In the marine littoral this is not an important problem as tides will replenish water in pools. Small rain pools are found in many tropical countries during the rainy season and these become incompletely dried at intervals. The biota of such pools must have resistant stages within the life cycle that enable them to cope with periods of drying. The most important potential effects of global warming include (i) the alteration of existing coastlines, (ii) the development of more deserts on some land masses, (iii) higher productivity producing higher crop production but a greater threat of algal blooms and (iv) the processing of organic matter at surface microlayers
Online Theological Education: Perspectives from First-Generation Asian Americans
This essay explores the use of online asynchronous discussions from the perspective of first-generation Asian American seminarians. The pedagogical paradigm implicit in these online forums assumes values that compete and even contradict the values these students bring from their native educational experiences. Combined with the language difficulties, asynchronous discussions can present a serious challenge to the educational goals of both the institution and the student. Despite these barriers, first-generation Asian American students often see the incorporation of the asynchronous discussions as a welcome enhancement to their theological education
How to Rewrite Torah: The Case for Proto-Sectarian Ideology in the Reworked Pentateuch (4QRP)
This study challenges the initial categorization of the Reworked Pentateuch (4Q364-4Q367) as another non-sectarian textual witness to the Torah. A close analysis of the manuscripts suggests that certain unaligned readings likely ret1ect some of the sectarian ideas of the community. Other variants evoke both content and ideology of the authoritative Rewritten Bible documents, the Temple Scroll and Jubilees. These characteristics imply that 4QRP contains deliberate reworking of biblical material that is in line with sectarian ideology, in contrast to a mere mechanical copying of the text. Though the scroll may not be strictly sectarian, at the very least, it is protosectarian in that 4QRP served as source material for the community\u27s ideology

von Neumann Stability Analysis of Globally Constraint-Preserving DGTD and PNPM Schemes for the Maxwell Equations using Multidimensional Riemann Solvers
The time-dependent equations of computational electrodynamics (CED) are
evolved consistent with the divergence constraints. As a result, there has been
a recent effort to design finite volume time domain (FVTD) and discontinuous
Galerkin time domain (DGTD) schemes that satisfy the same constraints and,
nevertheless, draw on recent advances in higher order Godunov methods. This
paper catalogues the first step in the design of globally constraint-preserving
DGTD schemes. The algorithms presented here are based on a novel DG-like method
that is applied to a Yee-type staggering of the electromagnetic field variables
in the faces of the mesh. The other two novel building blocks of the method
include constraint-preserving reconstruction of the electromagnetic fields and
multidimensional Riemann solvers; both of which have been developed in recent
years by the first author. We carry out a von Neumann stability analysis of the
entire suite of DGTD schemes for CED at orders of accuracy ranging from second
to fourth. A von Neumann stability analysis gives us the maximal CFL numbers
that can be sustained by the DGTD schemes presented here at all orders. It also
enables us to understand the wave propagation characteristics of the schemes in
various directions on a Cartesian mesh. We find that the CFL of DGTD schemes
decreases with increasing order. To counteract that, we also present
constraint-preserving PNPM schemes for CED. We find that the third and fourth
order constraint-preserving DGTD and P1PM schemes have some extremely
attractive properties when it comes to low-dispersion, low-dissipation
propagation of electromagnetic waves in multidimensions. Numerical accuracy
tests are also provided to support the von Neumann stability analysis
