Coping efficacy and psychological problems of children of divorce

Three models of the relations of coping efficacy, coping, and psychological problems of children of divorce were investigated. A structural equation model using cross-sectional data of 356 nine- to twelve-year-old children of divorce yielded results that supported coping efficacy as a mediator of the relations between both active coping and avoiding coping and psychological problems. In a prospective longitudinal model with a subsample of 162 of these children, support was found for Time 2 coping efficacy as a mediator of the relations between Time 1 active coping and Time 2 internalizing of problems. Individual growth curve models over four waves also found support for coping efficacy as a mediator of the relations between active coping and psychological problems. No support was found for alternative models of coping as a mediator of the relations between efficacy and symptoms or for coping efficacy as a moderator of the relations between coping and symptoms.     

Salient Effects of Practice Poster Sessions on Counselor Development: Implications for Research Training and Professional Identification

This study examined the effects of a 2-step practice poster session on first-year doctoral students' self-efficacy beliefs about making professional presentations, and evaluated the usefulness of an active-learning teaching assignment. Quantitative and qualitative data were collected from participants after each of 2 practice poster sessions. The results (a) suggest that the relatively brief training exercise significantly increased participants' self-efficacy to give scholarly presentations, and (b) replicate earlier reports about the usefulness of the learning assignment.     

Motivational factors in learning American sign lanquage

This study focuses on factors that motivate and demotivate professionals to learn American Sign Language (ASL). Using a qualitative approach known as the Critical Incident Technique (CIT), faculty and staff were asked to reflect on their sign language learning expericences, and their responses were examined for motivational patterns. Principal motivating factors were intrinsic in nature, including a desire to perform well in one's position, personal goals, and an interest in sign language per se. Integrative factors were also important, especially an interest in social interactions with deaf people. Principal factors that demotivated the respondents were more extrinsic in nature, dealing with workload, scheduling issues associated with the sign language curriculum, instruction, and the attitudes of self and others. We draw implications from the findings for the enhancement of sign language instruction programs.     

Recognition of substantial equivalence of engineering competence: the Canada—France mutual recognition agreement

Recognition at the full professional level of engineers coming from two different countries with totally different systems is a very difficult task. However, in the context of globalization of all human activities, particularly engineering services, it is essential that well-developed countries take very serious efforts using an open-minded approach to establish the parameters that will permit the ultimate objective of international recognition to be achieved. While there are many ways to move toward this objective, one recognized method of making very important steps is certainly the signature of mutual recognition agreements by major players in the trade of engineering services. In this context, this paper presents the features of a bilateral agreement that has been signed between France and Canada for the recognition of engineers at the full professional level from both countries. This agreement is the first of its kind for Canada. Many features of the agreement are worthy of note for others trying to identify the parameters to achieve an agreement between two countries having very different systems. How this success was achieved is explained, giving full attention to those factors that contributed to the conclusion of this agreement.     

Mathematics classrooms in Japan, Taiwan, and the United States

Observations were conducted in Chinese, Japanese, and American classrooms during mathematics classes. Activities in 20 representative classrooms were observed in each of 2 grades (1 and 5) and in each country. Some observations focused on individual children and others on the teachers. Large cross-cultural differences were found in many variables related to classroom structure and management. These differences paralleled differences in achievement in mathematics among the 3 countries. A number of these variables also were significantly related to average level of mathematics achievement within the American classrooms.     

Language in the Family Domain in Singapore: An Analysis of the 1980 Census Statistics

The 1980 population census of Singapore is the first census that gathered detailed information on languages spoken at home. The data were collected from the 20 per cent sample enumeration, using the following question:     

Walsh Operational Matrices for Fractional Calculus and Their Application to Distributed Systems

The Walsh operational matrix for performing integration and solving state equations is generalized to fractional calculus for investigating distributed systems. A new set of orthogonal functions is derived from Walsh functions. By using the new functions, the generalized Walsh operational matrices corresponding to √s, √(s²+ 1), e^-s and e^-√s etc. are established. Several distributed parameter problems are solved by the new approach.     

Probability of error in CPSK systems with intersymbol interference and additive noise

A simple lower bound, an upper bound and a simple approximation to the upper bound on the probability of error for coherent phase-shift-keyed (CPSK) systems operating in the presence of intersymbol interference and additive noise are obtained. The additive noises in the in-phase channel and the quadrature channel are assumed to be independent, and are independent of the signal, but not restricted to be Gaussian. The approximation to the upper bound is four times the lower bound, hence the tightness of these bounds is uniform for all cases. This fact and the simplicity of the bounds make these bounds a useful system design tool. Numerical examples for quaternary and octonary systems are presented and compared to known results.
