Review of Succeeding in private practice: A business guide for psychotherapists.

Reviews the book, Succeeding in private practice: A business guide for psychotherapists by Eileen S. Lenson (1994). Lenson, a social worker, has produced a usable and well thought out overview for any psychotherapy practitioner considering private practice. She suggests more than a dozen points such as freedom from routine, the need to be an energetic self-starter, and ability to delay gratification to determine fitness for private practice. After reviewing the various forms for a business (solo, partnership, corporation), Lenson outlines setting up an office and arranging for necessary supplies and services. Only a paragraph or so is allotted to each item, including computers, and the use of consultants such as accountants and attorneys. Lenson's real strengths are in the thorough and detailed discussion she provides for the business of doing business, including record keeping, fee setting, personnel issues, taxes, and marketing. She has drawn extensively from her own experience as well as from Psychotherapy Finances and Practice Builder, two specialized publications for professional practitioners. Chapters on office paperwork, insurance, and collections could stand alone as procedures manuals, they are so well-organized and comprehensive. Sample forms included are clear and attractively laid out. Succeeding in Private Practice is well-organized, attractively laid out with short paragraphs, thorough indexing, and numbered or bulleted lists. It lends itself well for use as a handbook since topics can be found easily. Let this book by Eileen Lenson be the first or second on a list for the beginning practitioner who must then go on to read many other works and seek advice from experienced psychotherapists in his or her own field.

Complexity of synthesis of composite service with correctness guarantee

How to compose existing web services automatically and to guarantee the correctness of the design (e.g. temporal constraints specified by temporal logic LTL, CTL or CTL*) is an important and challenging problem in web services. Most existing approaches use the process in conventional software development of design, verification, analysis and correction to guarantee the correctness of composite services, which makes the composition process both complex and time-consuming. In this paper, we focus on the synthesis problem of composite service; that is, for a given set of services and correctness constraint specified by CTL or CTL* formula, a composite service is automatically constructed which guarantees that the correctness is ensured. We prove that the synthesis problem for CTL and CTL* are complete for EXPTIME and 2EXPTIME, respectively. Moreover, for the case of synthesis failure, we discuss the problem of how to disable outputs of environment (i.e. users or services) reasonably to make synthesis successful, which are also proved complete for EXPTIME and 2EXPTIME for CTL and CTL*, respectively.
