The complexity of many organizational tasks requires perspectives, expertise, and talents that are often not found in a single individual. Organizations have therefore been placing employees into groups, assigning them to tasks they would formally have undertaken individually. The use of these groups, known as workgroups, has become an important strategy for managing this increased complexity. Empirical research on participative budgeting however has been limited almost exclusively to individuals. This dissertation empirically examines the effect of the information that management and workgroups have about group members' performance capabilities, on the work standards that workgroups select during the participative budgeting process. ^ A laboratory experiment was conducted in which two hundred and forty undergraduate business students were randomly assigned to three-member groups. The study provides empirical evidence which suggests that when management is unaware of group members' performance capabilities, workgroups select higher work standards and have higher performance levels than when management is aware of their performance capabilities. ^

Current views of the nature of knowledge and of learning suggest that instructional approaches in science education pay closer attention to how students learn rather than on teaching. This study examined the use of approaches to teaching science based on two contrasting perspectives in learning, social constructivist and traditional, and the effects they have on students' attitudes and achievement. Four categories of attitudes were measured using the Upper Secondary Attitude Questionnaire: Attitude towards school, towards the importance of science, towards science as a career, and towards science as a subject in school. Achievement was measured by average class grades and also with a researcher/teacher constructed 30-item test that involved three sub-scales of items based on knowledge, and applications involving near-transfer and far-transfer of concepts. The sample consisted of 202 students in nine intact classrooms in chemistry at a large high school in Miami, Florida, and involved two teachers. Results were analyzed using a two-way analysis of covariance (ANCOVA) with a pretest in attitude as the covariate for attitudes and prior achievement as the covariate for achievement. A comparison of the adjusted mean scores was made between the two groups and between females and males. ^ With constructivist-based teaching, students showed more favorable attitude towards science as a subject, obtained significantly higher scores in class achievement, total achievement and achievement on the knowledge sub-scale of the knowledge and application test. Students in the traditional group showed more favorable attitude towards school. Females showed significantly more positive attitude towards the importance of science and obtained significantly higher scores in class achievement. No significant interaction effects were obtained for method of instruction by gender. ^ This study lends some support to the view that constructivist-based approaches to teaching science is a viable alternative to traditional modes of teaching. It is suggested that in science education, more consideration be given to those aspects of classroom teaching that foster closer coordination between social influences and individual learning. ^

Current reform initiatives recommend that school geometry teaching and learning include the study of three-dimensional geometric objects and provide students with opportunities to use spatial abilities in mathematical tasks. Two ways of using Geometer's Sketchpad (GSP), a dynamic and interactive computer program, in conjunction with manipulatives enable students to investigate and explore geometric concepts, especially when used in a constructivist setting. Research on spatial abilities has focused on visual reasoning to improve visualization skills. This dissertation investigated the hypothesis that connecting visual and analytic reasoning may better improve students' spatial visualization abilities as compared to instruction that makes little or no use of the connection of the two. Data were collected using the Purdue Spatial Visualization Tests (PSVT) administered as a pretest and posttest to a control and two experimental groups. Sixty-four 10th grade students in three geometry classrooms participated in the study during 6 weeks. Research questions were answered using statistical procedures. An analysis of covariance was used for a quantitative analysis, whereas a description of students' visual-analytic processing strategies was presented using qualitative methods. The quantitative results indicated that there were significant differences in gender, but not in the group factor. However, when analyzing a sub sample of 33 participants with pretest scores below the 50th percentile, males in one of the experimental groups significantly benefited from the treatment. A review of previous research also indicated that students with low visualization skills benefited more than those with higher visualization skills. The qualitative results showed that girls were more sophisticated in their visual-analytic processing strategies to solve three-dimensional tasks. It is recommended that the teaching and learning of spatial visualization start in the middle school, prior to students' more rigorous mathematics exposure in high school. A duration longer than 6 weeks for treatments in similar future research studies is also recommended.

Adult educators are only beginning to understand the interaction between learning and emotion (Dirkx, 2006; O’Regan, 2003). Understanding these concepts and their interaction through the constructivist perspective presents a unique opportunity to appreciate the learner’s perspective and the construction of knowledge through experience.

In their discussion - Participative Budgeting and Participant Motivation: A Review of the Literature - by Frederick J. Demicco, Assistant Professor, School of Hotel, Restaurant and Institutional Management, The Pennsylvania State University and Steven J. Dempsey, Fulton F. Galer, Martin Baker, Graduate Assistants, College of Business at Virginia Polytechnic Institute and State University, the authors initially observe: “In recent years behavioral literature has stressed the importance of participation In goal-setting by those most directly affected by those goals. The common postulate is that greater participation by employees in the various management functions, especially the planning function, will lead to improved motivation, performance, coordination, and functional behavior. The authors analyze this postulate as it relates to the budgeting process and discuss whether or not participative budgeting has a significant positive impact on the motivations of budget participants.” In defining the concept of budgeting, the authors offer: “Budgeting is usually viewed as encompassing the preparation and adoption of a detailed financial operating plan…” In furthering that statement they also furnish that budgeting’s focus is to influence, in a positive way, how managers plan and coordinate the activities of a property in a way that will enhance their own performance. In essence, framing an organization within its described boundaries, and realizing its established goals. The authors will have you know, to control budget is to control operations. What kind of parallels can be drawn between the technical methods and procedures of budgeting, and managerial behavior? “In an effort to answer this question, Ronen and Livingstone have suggested that a fourth objective of budgeting exists, that of motivation,” say the authors with attribution. “The managerial function of motivation is manipulative in nature.” Demicco, Dempsey, Galer, and Baker attempt to quantify motivation as a psychological premise using the expectancy theory, which encompasses empirical support, intuitive appeal, and ease of application to the budgetary process. They also present you with House's Path-Goal model; essentially a mathematics type formula designed to gauge motivation. You really need to see this. The views of Argyris are also explored in particular detail. Although, the Argyris study was primarily aimed at manufacturing firms, and the effects on line-supervisors of the manufacturing budgets which were used to control and evaluate their performance, its application is relevant to the hospitality industry. As the title suggests, other notables in the field of behavioral motivation theory, and participation are also referenced. “Behavioral theory has been moving away from models of purported general applicability toward contingency models that are suited for particular situations,” say the authors in closing. “It is conceivable that some time in the future, contingency models will make possible the tailoring of budget strategies to individual budget holder personalities.”

A constructivist philosophy underlies the Irish primary mathematics curriculum. As constructivism is a theory of learning its implications for teaching need to be addressed. This study explores the experiences of four senior class primary teachers as they endeavour to teach mathematics from a constructivist-compatible perspective with primary school children in Ireland over a school-year period. Such a perspective implies that children should take ownership of their learning while working in groups on tasks which challenge them at their zone of proximal development. The key question on which the research is based is: to what extent will an exposure to constructivism and its implications for the classroom impact on teaching practices within the senior primary mathematics classroom in both the short and longer term? Although several perspectives on constructivism have evolved (von Glaserfeld (1995), Cobb and Yackel (1996), Ernest (1991,1998)), it is the synthesis of the emergent perspective which becomes pivotal to the Irish primary mathematics curriculum. Tracking the development of four primary teachers in a professional learning initiative involving constructivist-compatible approaches necessitated the use of Borko’s (2004) Phase 1 research methodology to account for the evolution in teachers’ understanding of constructivism. Teachers’ and pupils’ viewpoints were recorded using both audio and video technology. Teachers were interviewed at the beginning and end of the project and also one year on to ascertain how their views had evolved. Pupils were interviewed at the end of the project only. The data were analysed from a Jaworskian perspective i.e. using the categories of her Teaching Triad of management of learning, mathematical challenge and sensitivity to students. Management of learning concerns how the teacher organises her classroom to maximise learning opportunities for pupils. Mathematical challenge is reminiscent of the Vygotskian (1978) construct of the zone of proximal development. Sensitivity to students involves a consciousness on the part of the teacher as to how pupils are progressing with a mathematical task and whether or not to intervene to scaffold their learning. Through this analysis a synthesis of the teachers’ interpretations of constructivist philosophy with concomitant implications for theory, policy and practice emerges. The study identifies strategies for teachers wishing to adopt a constructivist-compatible approach to their work. Like O’Shea (2009) it also highlights the likely difficulties to be experienced by such teachers as they move from utilising teacher-dominated methods of teaching mathematics to ones in which pupils have more ownership over their learning.

Le principe de coopération est considéré depuis longtemps comme l’une des pierres angulaires du droit international, toutefois, l’existence d’une obligation de coopérer en droit international reste encore controversée. Les ressources en eau, à cause de leur fluidité et de leurs multiples usages, démontrent toujours l’interdépendance humaine. En matière de cours d’eau transfrontaliers, la Convention de New York inclut explicitement dans son texte l’obligation générale de coopérer comme l’un de ses trois principes fondamentaux. Il nous incombe alors de voir quelle obligation de coopérer les États souverains s’imposent dans leurs pratiques ? Pour répondre à cette question, nous procédons tout d’abord à une étude positiviste du contenu normatif de l’obligation de coopérer. Nous constatons que l’incorporation de la notion de l’obligation de coopérer dans le principe de la souveraineté est une tendance manifeste du droit international qui a évolué du droit de coexistence composé principalement des règles d’abstention, au droit de coopération qui comporte essentiellement des obligations positives de facere, dont la plus représentative est l’obligation de coopérer. Néanmoins, il n’existe pas de modèle unique d’application pour tous les États, chaque bassin disposant de son propre régime coopératif. Pour mesurer l’ampleur des régimes coopératifs, nous étudions cinq paramètres : le champ d’application, les règles substantielles, les règles procédurales, les arrangements institutionnels et le règlement des différends. Quatres modèles de coopération ressortent : le mécanisme consultatif (l’Indus), le mécanisme communicateur (le Mékong), le mécanisme de coordination (le Rhin) et le mécanisme d’action conjointe (le fleuve Sénégal). Pour ce qui est de la Chine, il s’agit de l’État d’amont en voie de développement le plus important dans le monde qui a longtemps été critiqué pour son approche unilatérale dans le développement des eaux transfrontières. Nous ne pouvons pas cependant passer sous silence les pratiques de coopération qu’elle a développées avec ses voisins. Quelle est son interprétation de cette obligation générale de coopérer ? Notre étude des pratiques de la Chine nous aide, en prenant du recul, à mieux comprendre tous les aspects de cette obligation de coopérer en droit international. Afin d’expliquer les raisons qui se cachent derrière son choix de mode de coopération, nous introduisons une analyse constructiviste qui est plus explicative que descriptive. Nous soutenons que ce sont les identités de la Chine qui ont déterminé son choix de coopération en matière de cours d’eau transfrontaliers. Notre étude en vient à la conclusion que même s’il y a des règles généralement reconnues, l’obligation de coopérer reste une règle émergente en droit international coutumier. Ses modes d’application sont en réalité une construction sociale qui évolue et qui peut varier énormément selon les facteurs culturels, historiques ou économiques des États riverains, en d’autres mots, selon les identités de ces États. La Chine est un État d’amont en voie de développement qui continue à insister sur le principe de la souveraineté. Par conséquent, elle opte pour son propre mécanisme consultatif de coopération pour l’utilisation des ressources en eau transfrontalières. Néanmoins, avec l’évolution de ses identités en tant que superpuissance émergente, nous pouvons probablement espérer qu’au lieu de rechercher un pouvoir hégémonique et d’appliquer une stratégie unilatérale sur l’utilisation des ressources en eau transfrontalières, la Chine adoptera une stratégie plus coopérative et plus participative dans l’avenir.

La cartographie participative est l’une des multiples disciplines de la géomatique. Elle a débuté dans les années 1980 afin d’aider les populations locales des pays du Sud à développer leur territoire. C’est en Nouvelle-Calédonie, dans la tribu de Wan Pwec que nous allons voir les intérêts, d’un tel processus de cartographie participative. Il est important de souligner que ce n’est pas pour développer son territoire que cette discipline est utilisée, mais plutôt pour montrer et démontrer les logiques traditionnelles de gestion de la terre existant dans les tribus kanak : logiques traditionnelles basées sur un savoir transmis de génération en génération de façon orale. C’est sur les terres coutumières de la tribu de Wan Pwec, que nous allons voir comment la vision mentale possédée par les chefs de familles et le chef de clan administre et gère les terres familiales. C’est dans une société kanak caractérisée par une forte tradition orale et n’ayant connu aucun support papier pour conserver et archiver ses connaissances que ce mémoire s’incorpore. À l’aide de la géomatique, d’une étude de cas sur le terrain et d’autres disciplines (comme l’anthropologie, le droit, l’histoire, la géographie, etc.), ce mémoire propose les résultats de ses travaux sur le savoir traditionnel du foncier coutumier.
