"Three distinctive themes have guided our efforts in writing this book, and they are woven throughout the text. The first is intimacy, and our focus is on how to develop and maintain close relationships. Most people seek connectedness and want to be involved in intimate relationships, the most intimate being marriage and family. This book is full of ideas, principles, and suggestions for building and keeping intimate relationships in your life. As a result, we hope this will be a book that you will want to keep and refer to throughout your life. The second key theme is marital and family strengths. The family strengths perspective is based on the premise that if you approach relationships from a "problem-oriented" perspective, you will find problems. If you look for strengths, you will find strengths. Growing numbers of family educators and family therapists are using this approach today, helping families recognize their own strengths and use them as a foundation for positive growth. In Chapter 1, we identify a number of strengths that have been found to be present in healthy marriages and families all over the world. Throughout the book, we show how these strengths help families provide healthy and nurturing settings that promote the growth and well-being of individual family members, better enabling them to face the challenges and solve the problems they encounter"--

Families in Disaster research has drawn heavily from the family stress and crises research paradigms and concepts advanced by Reuben Hill's ABC-X Model and by related research. This article attempts to broaden the perspective of family behavior in disaster situations by advancing additional concepts, definitions and propositions. Findings from longitudinal research on American families faced with the historically unique traumatic situation of having a husband/father held captive or unaccounted for in the Vietnam War were analyzed first in reference to the ABC-X Model, which suggested the need to expand this classic model. This article introduces the Double ABC-X Model in an effort to capture the dynamic nature of family response to stress over time. This expanded model includes: AA-the family's pile up of life events and stressors over time; BB-the family's resources which are strenghened or developed within and in transaction with the community and include coping and social support; CC-the family's perception of the stressor and related changes in the family; and XX-the additional end state of family adaptation following a crisis. This model merits careful consideration and additional testing in light of stress and disaster studies reviewed and propositions advanced during the past decade.

As an alternative technology to energy intensive distillations, adsorptive separation by porous solids offers lower energy cost and higher efficiency. Herein we report a topology-directed design and synthesis of a series of Zr-based metal-organic frameworks with optimized pore structure for efficient separation of C6 alkane isomers, a critical step in the petroleum refining process to produce gasoline with high octane rating. Zr6O4(OH)4(bptc)3 adsorbs a large amount of n-hexane but excluding branched isomers. The n-hexane uptake is ~70% higher than that of a benchmark adsorbent, zeolite-5A. A derivative structure, Zr6O4(OH)8(H2O)4(abtc)2, is capable of discriminating all three C6 isomers and yielding a high separation factor for 3-methylpentane over 2,3-dimethylbutane. This property is critical for producing gasoline with further improved quality. Multicomponent breakthrough experiments provide a quantitative measure of the capability of these materials for separation of C6 alkane isomers. A detailed structural analysis reveals the unique topology, connectivity and relationship of these compounds. ; We would like to thank the financial support from the Materials Sciences and Engineering Division, Office of Basic Research Energy Sciences of the U.S. Department of Energy through Grant no.
