This article discusses a technique the authors have designated Family Photo Reconnaisance. They describe the rationale for and process of utilizatizing family photographs and movies in family therapy sessions to evoke past events and memories and to uncover feelings about these occurrences and the people involved in them. Through their utilization, how one has changed over time is vividly seen. Who is missing from the constellation and when they "dropped out of the family orbit becomes obvious as do distorted memories. Family members reexperiencing the past together around their photographs come to better appreciate one another's current feelings and behavior and often are enabled to gain mastery over unresolved conflicts. 相似文献

Continuous passive motion (CPM) has been proposed as a method to help individuals with low back pain cope with prolonged sitting. The purpose of this study was to investigate the effects that a commercially available CPM device had on lumbar and thoracic erector spinae (ES) muscle activation (using surface electromyography, "EMG"), and on subjective discomfort during prolonged seated computer work with and without the use of the CPM device. There were no significant differences in average ES muscle activation levels, amplitude probability distribution functions, and EMG gaps number and length when sitting with the CPM device was compared to sitting normally. Subjective ratings of discomfort were also not significantly different between the two sitting conditions. The results indicated that there were no clear mechanisms by which the CPM device may reduce ES muscle pain and fatigue for the tasks and pain-free individuals studied. 相似文献

Volunteer contributions in the production of services are an important resource internationally. However, few countries include volunteer contributions in their national accounts, even though many encourage their populations to engage in volunteering. At the organizational level, many nonprofit organizations using volunteers often limit their input to a footnote in annual reports acknowledging their contribution; few estimate their value in financial terms. As a result, their financial accounts lack information upon which to base decisions affecting the organizations and the communities they serve. Additional information is required to assess the impact of volunteers in individual nonprofits as well as the sector as a whole. This study focuses on Canada, one of the few countries that include volunteers in the national accounts, to examine to what extent nonprofit organizations estimate a financial value for these contributions and include this in their financial statements. This paper reports the results of an online survey of 661 nonprofits from across Canada. In order to understand why some organizations keep records for volunteer contributions and quantify them, two sets of explanatory factors are explored: organizational characteristics and the attitude of the executive director. We find larger organizations were more likely to engage in record keeping and estimating volunteer value, as were organizations with a relatively large group of volunteers and volunteer programs. The attitude of the executive director is important in determining which organizations engage in these practices. 相似文献

An effective and efficient search algorithm has been developed to select from an 1(1) system zero-non-zero patterned cointegrating and loading vectors in a subset VECM, Bq(l)y(t-1) + Bq-1 (L)Ay(t) = ε( t ) , where the long term impact matrix Bq(l) contains zero entries. The algorithm can be applied to higher order integrated systems. The Finnish money-output model presented by Johansen and Juselius (1990) and the United States balanced growth model presented by King, Plosser, Stock and Watson (1991) are used to demonstrate the usefulness of this algorithm in examining the cointegrating relationships in vector time series. 相似文献
