The goal of this inductive study was to identify factors that facilitate and inhibit binational collaboration in the recovery of endangered species in the northern Mexico borderlands, focusing on the Mexican wolf (Canis lupus baileyi). A conceptual model was developed using qualitative techniques, providing the basis for design of a mail survey. The target population included participants with experience in recovery efforts for over a dozen species at risk in the region. Long interviews were recorded with 44 participants from Mexico and the United States. Thematic hierarchical analysis was used to develop a conceptual model of how interviewees talked about factors influencing binational collaboration. Issues were classified in five thematic clusters: project, organization, people, resources, culture/history. The survey was used to conduct a needs assessment, measuring respondents' attitudes about the relative priority of issues identified in the conceptual model. High priority needs were identified from each thematic cluster: (a) equitable participation in project design and implementation, (b) continuity of personnel, (c) coordination of federal, state and local efforts, (d) increased funding, managed with accountability, and (e) exchange visits to facilitate understanding of diverse perspectives. Responses to almost half the survey items indicated accord among the sample of respondents, providing a basis for shared common ground. The nature of discord was within the range of "manageable", with no clear polarization of attitudes measured. This exploratory data analysis suggested that the structure of the conceptual model developed from the Mexican wolf case study was generally a valid basis for future deductive analysis and reflection by practitioners. For 82% of 22 statements of need, priorities of participants in the Mexican wolf recovery efforts did not differ significantly from other respondents. Nationality (of respondents) significantly affected priority rankings for only 18% of the need statements. Significant effects of five demographic variables indicated that interactive effects should be examined in future multivariate analyses to determine how respondents' attitudes on issues related to priority rankings. Recommendations were provided for a more efficient and effective approach to collaborative problem-solving, engaging reflective practitioners from the private and public sectors in principled negotiation processes to better understand diverse perspectives.

Regular exercise is challenging and lapses in activity may lead to non-adherence. Adherence may be particularly challenging for symptomatic individuals with disease-related symptoms that may impede exercise. The combined use of cognitive-behavioural strategies including problem-solving has been strongly encouraged for promoting exercise adherence. However, evidence supporting the link between the use of the independent strategy of problem-solving and exercise adherence is limited. The overall purpose of this dissertation was to examine problem-solving relative to exercise-lapse related problems. Using two theoretical frameworks that offer insight into problem-solving (Model of Social Problem-Solving and Social Cognitive Theory), three studies were conducted to examine proposed relationships in various asymptomatic and symptomatic exercising samples. In Study 1A, relationships between self-regulatory efficacy (SRE) for exercise and problem-solving approach (task-diagnostic and self-diagnostic) were explored in a sample of exercising university students (n = 79). Results indicated that SRE beliefs were significantly and (1) positively related to task-diagnostic problem-solving approach and (2) negatively related to self-diagnostic problem-solving approach. In Study 1B, relationships between problem-solving effectiveness and exercise-related social cognitions were examined in the same sample. Findings demonstrated that problem-solving effectiveness was positively associated with social cognitive correlates of exercise adherence linked to adaptation. Relationships demonstrated in Study 1 provide preliminary support for previously unexamined problem-solving research questions relative to exercise. In Study 2, relationships between problem-solving effectiveness and exercise-related social cognitions (self-efficacy and persistence) were examined in a sample of exercising cardiac rehabilitation initiates (n = 52). These relationships were considered relative to two distinct components of the problem-solving process (seeking solutions to problems and carrying out solutions), which have not previously been examined relative to exercise lapses. Findings indicated significant relationships between problem-solving effectiveness and (a) self-efficacy for problem-solving (seeking solutions to problems), (b) persistence with problem-solving, (c) self-efficacy for solution implementation (carrying out solutions) and (d) persistence with solution implementation. In Study 3, problem-solving was examined among exercising cancer survivors (n = 35) with cancer-related fatigue, a problematic exercise barrier. Partial support was demonstrated for differences between more and less effective problem-solvers on fatigue-related variables. An under-examined area in problem-solving research was also examined in this study; the relationship between problem-solving and positive psychological functioning. Findings indicated significant differences for positive psychological functioning between individuals with higher and lower positive problem orientation. Taken together, the three studies represent an initial attempt to advance exercise and problem-solving literature by illustrating important theoretical relationships in three samples of exercisers, and addressing important gaps in the exercise and problem-solving literature. In regard to the latter point, the research was the first to examine (a) variables that may link problem-solving to exercise adherence, (b) two distinct components of the problem-solving process relative to an exercise lapse situation, and (c) potential links between problem-solving and selected positive psychological outcomes. Future research directions relative to problem-solving and exercise are suggested as possible next steps to advance this preliminary research.

Purpose of the Investigation. The purpose of this investigation was to determine whether a treatment of design-related heuristics would affect the judged value of student design products. Procedures. Subjects consisted of 38 foundation-level design students at Ball State University, Muncie, Indiana. Following five weeks of basic design instruction, a pretest, constructed to measure design problem-solving performance in relation to two problem-types (a Baseline Problem and a Conceptual Problem), was issued to two groups. Thereafter, a treatment of design-related heuristics was administered to one group; the other group served as a control. After a period of four weeks, in which both groups worked an identical series of problems, a post-test was issued.Evaluation of pre-test and post-test designs was performed by five designer/educators using a Design Evaluation Rating Scale, an instrument used to quantify judgments regarding six discrete evaluative criteria (i.e., General Impression, Completion, Figural Originality, Conceptual Originality, Aesthetic Value, and Functionalness). Two null hypotheses were tested which maintained that no significant interaction effects would occur for either the Baseline Problem or the Conceptual Problem between factors of (a) time-of-test (pre-test, post-test) and (b) group (experimental, control) for seven dependent variables (i.e., Overall Score, General Impression, Completion, Figural Originality, Conceptual Originality, Aesthetic Value, Functionalness). The .05 level of confidence was set as the critical level for rejection of hypotheses. Inter-rater reliability was computed, and found to be high for three of the four test problems.Results and'Conclusions1. Null Hypothesis Number one was rejected, suggesting that the heuristics treatment aided the experimental group in their performance on the Baseline Problem. Null Hypothesis Number Two was not rejected, suggesting that the treatment failed to aid the experimental group in their performance on the Conceptual Problem.2. Problem structure apparently affected the design problem-solving behavior and performance of the foundation-level design students, suggesting that highly complex or abstract problems are best reserved for more advanced design courses.3. A measured construct of "design value" can be operationally defined and expert judgments thereby quantified to validly measure the real-world value of design products

Numerous cognitive, personality and situational factors have been found to be related to aggression. Understanding how these factors interrelate is essential to predicting violence and critical to the assessment and treatment of offenders with violent histories. Previous research has suggested a potential role for social problem solving as a mediator between impulsivity and aggression (McMurran et al., 2002). Additionally, it is well established that aggression is more likely to occur in the context of alcohol use (Collins, 1993; Reiss & Roth, 1993; Lipsey, Wilson, Cohen & Derzon 1997). Based on existing literature, a model of aggression was developed involving impulsivity, social problem solving and alcohol dependency. Utilizing path analysis with multiple regression, a mediational model of aggression was assessed on a sample of 179 provincially incarcerated offenders, 87% of whom were Aboriginal and 45% of whom had a previous conviction of domestic abuse. The data suggest that social problem solving, alcohol dependency and impulsivity are all important in understanding and predicting aggression. Social problem solving does not appear to act as a mediator in the relationship between impulsivity and aggression, although preliminary results suggest that impulsivity, may serve the function in this relationship and in the manifestation of aggression. The implications of these findings for our understanding about human factors contributing to aggression and for further advancement of treatment programs are provided.

The purpose of this study was to, from the teacher's point of view; discover pupils with reading difficulties in connection with text assignments in mathematics, the teacher's support for these students, if difficulties coincide and whether it's the mathematics teacher's responsibility to make sure pupils with reading difficulties develop their reading ability. The study is based on a qualitative method and five semistructured interviews with mathematics teachers and one language support teacher. The result shows there is a strong connection between the pupils' reading ability and their ability to manage text assignments in mathematics. A weak reading ability affects the pupil in a negative way when solving text assignments in mathematics due to wrong reading technique if the teacher is absent. It is not unusual that reading difficulties and mathematics difficulties coincide. The teacher's most important role in the learning process is to teach the pupils understanding about the reading technique in different ways and to give the pupils opportunity to get spoken texts. It is not the mathematics teacher's responsibility to make sure pupils with reading difficulties develop their reading ability, rather it's the responsibility of a specialist and professional reading- and writing support teacher.

In this thesis we study four groups of students in grade 8, 9 and 10 when they try to solve a classical mathematical problem: Which rectangle with given circumference has the largest area? The aim of the study was too see how the students did to solve a mathematichal problem? The survey shows that students have rather poor strategies to solve mathematical problems. The most common mistake is that students don’t put much energy to understand the problem before trying to solve it. They have no strategies. This was clearly obvious when you look at Balacheff’s theory in an article from 1988. His first, and lowest, level is called naive empiricism. Typical for that level was that the student’s efforts to solve the problem just consisted of social interaction without any direction and structure. One reason can be that the students don’t recognize mathematical laws and general concepts well enough. Another problem is that they don’t check their results. Why they don’t do this is hard to say. Earlier results indicating that one reason can be that the students don’t take tasks in school as an intellectual challenge. The just consider it like something the must do.

Denna undersökning handlar om elevers val av strategier när de löser matematiska textuppgifter i årskurs tre. I undersökningen har sammanlagt tolv elever medverkat från två landsbygdsskolor i Kalmar län. Studien genomfördes med hjälp av enkäter, intervjuer samt observationer. Enkätsvaren, intervjuerna samt observations-anteckningarna har analyserats för att finna de olika strategier som används av eleverna i årskurs tre. Bilder och huvudräkning var de två strategier som förekom i högre grad. Eleverna använde sig även av uppställningar. Det har även visat sig att elevernas erfarenheter av textuppgifter har varit begränsade. / This study is about pupils’ choice of strategies when they solve text tasks in mathematics in the third grade. In the study two classes participated with the total of twelve students from two rural schools in Kalmar County. The study was conducted using questionnaires, interviews and observations, which have been analyzed to identify the different strategies used by the students. It turned out that two strategies were more used than others, these were pictures and mental arithmetic, but used less of calculation. It has also shown that pupils’ experiences of text tasks have been limited.
