The purpose of this study was to investigate the relationship of family size, birth order, socioeconomic status, and parent-child relationships to young children's intellectual development. Seventy-four children, 39 boys and 35 girls, with a mean age of 4 years-8 months, and their parents (mothers and fathers), selected from 9 preschool programs and daycare centers in Corvallis, Oregon, acted as subjects for this study. Ninety-five percent of the families came from upper or upper-middle socioeconomic classes. All the families were intact, consisting of children and their biological parents, representing one-, two, and three-child families. The children in this study were either first-, second- or third-born children. Family socioeconomic status was determined via Hollingshead's Four Factor Index of Social Status. Information on family size and birth order was obtained through a Demographic Questionnaire. Parent-child relationship was assessed via the Parent Attitude Research Instrument-Short Form. Children's intellectual level was measured with the Peabody Picture Vocabulary Test-Revised. Zajonc and Markus' Confluence Theory, Page and Grandon's Admixture Theory, and Falbo and Polies Parent-Child Relationships Theory were utilized as the basis for investigating the relative contributions of family size, birth order, socioeconomic status, mother-child relationship, and father-child relationship to children's intellectual development. The regression procedure was used in data analyses. The .05 probability level was used as the criterion for statistical significance. Findings revealed that the variables of socioeconomic status and quality of father-child relationships contributed significantly to children's intellectual development. The higher the socioeconomic status of the family, and the more supportive the father-child relationships, the higher the children's intellectual development scores. Birth order and family size made no contributions to children's intellectual development. These findings, therefore, provided support for Page and Grandon's Admixture Theory and Falbo and Polies Parent-Child Relationships Theory, but not for Zajonc and Markus' Confluence Theory. / Graduation date: 1995

Electromigration tests on different Cu dual-damascene interconnect tree structures consisting of various numbers of straight via-to-via lines connected at the common middle terminal have been carried out. Like Al-based interconnects, the reliability of a segment in a Cu-based interconnect tree strongly depends on the stress conditions of connected segments. The analytic model based on a nodal analysis developed for Al trees gives a conservative estimate of the lifetime of Cu-based interconnect trees. However, there are important differences in the results obtained under similar test conditions for Al-based and Cu-based interconnect trees. These differences are attributed to the variations in the architectural schemes of the two metallization systems. The absence of a conducting electromigration-resistant overlayer in Cu technology and the low critical stress for void nucleation at the Cu/inter-level diffusion barrier (i.e. Si₃N₄) interface leads to different failure modes between Cu and Al interconnects. As a result, the most highly stressed segment in a Cu-based interconnect tree is not always the least reliable. Moreover, the possibility of liner rupture at stressed dual-damascene vias leads to significant differences in tree reliabilities in Cu compared to Al. While an interconnect tree can be treated as a fundamental unit whose reliability is independent of that of other units in Al-based interconnect architectures, interconnect trees can not be treated as fundamental units for circuit-level reliability analyses for Cu-based interconnects. / Singapore-MIT Alliance (SMA)

The single biggest challenge facing municipalities today is a shortage of funds and labor for upgrading and expanding aging infrastructure. This continued lack of funding impairs the municipalities ability to maintain desired levels of service. Over the last decade, many Canadian municipalities have faced pressures of increasing complexity in infrastructure asset management decision-making which can be partly attributed to cost escalation, increasing service demand and interdependencies between networks. The goal of this research is to develop the framework for Asset Levels of Service (ALOS)-based decision support systems for municipal infrastructure network investment. The proposed framework is based on the fact that ALOS should be one of the main criteria for municipal infrastructure maintenance, repair and rehabilitation (MR&R). Since ALOS is based on qualitative and quantitative parameters, the use of ALOS in municipal infrastructure MR&R decisions will result in improved funding allocation. Secondary parameters used for municipal infrastructure investment decision making in the proposed framework are the physical deterioration of assets, future growth and the impact on the dependent infrastructure network. The proposed framework focuses on funding allocation for the MR&R of municipal networks. The framework is applicable to municipal infrastructure networks, excluding the other assets such as buildings, parks, etc. Application of the proposed framework is demonstrated by its implementation in the case of urban roads. Implementation is carried out in four phases. Phase I involves the quantification of ALOS for urban roads. Quantification of ALOS for urban roads has various challenges such as multiple users and interdependencies of levels of services between various users. An Analytical Hierarchy Process (AHP) has been used to quantify ALOS. Phase II involves the determination of a multiattribute utility function for investment decision. Calculated multiattribute utility of investment decision is used in the multiobjective optimization model in Phase III. In Phase IV, the proposed methodology is incorporated into a computer application called OPTIsys (OPTImum Infrastructure SYStems). OPTIsys will facilitate MR&R decision making based on fully integrated considerations of ALOS, future demand and network interdependencies. Stakeholders benefiting from OPTIsys include the general public, asset-managers, infrastructure departments and municipal councils. OPTIsys will enable infrastructure departments to maintain the operational capability of the network in compliance with the targeted levels of service. Overall, municipalities will be able to reduce the infrastructure deficit while maximizing economic returns. / Construction Engineering and Management

Abstract: This dissertation is a case study of one teacher who participated in a project that investigated the effects of the Texas Instruments NavigatorTM, a wireless communication system on student algebra achievement and related pedagogy. The larger study, Classroom Connectivity in Promoting Mathematics and Science Achievement (CCMS) based at The Ohio State University (OSU), funded by the U. S. Department of Education, involved approximately 120 self-selected participants across the United States. A partial requirement for participation was agreement to attend professional development provided by the CCMS project. The professional development included a week-long summer institute at OSU prior to implementation of the TI-NavigatorTM, attendance at annual International T3 meetings, participation in the cohort listserve, and semi-annual telephone interviews. During data collection of the CCMS project, many of the participants exhibited an enthusiasm for implementation of the tool and the pedagogy supported by the CCMS project. The subject of this case study, Mrs. G, was among those perceived as high implementers. This longitudinal study attempts to verify alignment of her instruction with the pedagogy promoted in the professional development sessions provided by the project. Transcripts from professional development sessions were compared with Mrs. G’s comments about her perception of her implementation of the project. Transcribed classroom observations were then analyzed using NVivo software to quantify evidence of implementation of the pedagogy with respect to the three constructs of classroom discourse, levels of questioning and formative assessment. The results of the analyses indicated that Mrs. G implemented the pedagogy advocated by the professional development sessions of the CCMS project. According to the literature key elements were in place for successful professional development. The teacher was allowed autonomy and choice in her professional development In Mrs. G’s words, “Professional development must be relevant to my profession and support my goals… student understanding.” Implications are that pre-service programs should instill in prospective teachers the importance of life-long learning and equip them with strategies to seek out professional development opportunities that are relevant to them. In-service teachers should in turn be given autonomy and choice in determining which professional development opportunities will complement their programs.

If we want to compare the explanatory and descriptive adequacy of the MP and OT, the original definitions by Chomsky (1964) are or little direct use. However, a relativized version of both notions can be defined, which can be used to express a number of parallels between the study of individual I-languages and the language faculty. In any version of explanatory and descriptive adequacy, the two notions derive from the research programme and can only be achieved together. They can therefore not be used to characterize the difference in orientation between OT and the MP. Even if ‘OT’ is restricted to a particular theory in Chomskyan linguistics (to the exclusion of, for instance, its use in LFG), it cannot be said to be stronger in descriptive adequacy than in explanatory adequacy in the technical sense of these terms.

Background: The description of different characters in soapoperas are often exaggerated to catch the viewers interest and to present an exiting content. The phenomenon that takes place in soapoperas can often relates to every-day- life-situations. The viewers should recognise them selves in the content, the imaginary situations and the characters should be normal but at the same time exaggerated and twisted to catch the viewers attention. This means that the characters in Rederiet should have connections to the real world and this makes it interesting to study how the different styels of leadership are descibed. Purpose: The purpose is to analyse and compare three choosen characters in the soapopera Rederiet, from existing leadership thoeries. To identify leadership on three hierarchical levels – head of machinery, superintendent and captain – and to analyse how leadership are descibed in the soapopera. Realization: The study is based on videotaped episodes of the soapopera Rederiet. Conclusion: The mediate illustrations can be compared to the scientific theories. The three managers are different from eachother. Leadership depends on the managers acting, in the soapopera and in real life. The mediate illustrations shows that leadership are different and dependent on personality and hierarchical position. This holds for Rederiet and for real organizations.

Background: Companies today are under increasing pressure from their stakeholders to become more and more transparent regarding the way they deal with the impact on the environment and the communities where they operate in. This type of information is mainly provided by means of sustainability reports. Several guidelines have been developed to aid report makers on the way. Currently however these sustainability reports still differ widely in the quantity of information provided which makes them difficult to compare and it is therefore important to understand the factors that can influence the amount of information being published. Purpose: The purpose of this study is to identify the factors having an impact on the amount of sustainability information published by Swedish companies using the guidelines developed by the Global Reporting Initiative (GRI). Method: Telephone interviews were conducted with eleven of the twenty-three Swedish companies listed in the GRI register in order to get their point of view regarding these factors. Results: The study identified that the willingness to communicate with more than one stakeholder group is the most important factor that can influence the amount of information disclosed in sustainability reports. The authors also argue that a proactive attitude towards identifying legitimation strategies instead of an adaptive approach can also influence the degree of disclosure. Finally, a positive attitude towards the GRI guidelines may also contribute to producing a more detailed report.

Neural networks underpinning working memory demonstrate sign language specific components possibly related to differences in temporary storage mechanisms. A processing approach to memory systems suggests that the organisation of memory storage is related to type of memory processing as well. In the present study, we investigated for the first time semantic, phonological and orthographic processing in working memory for sign- and speech-based language. During fMRI we administered a picture-based 2-back working memory task with Semantic, Phonological, Orthographic and Baseline conditions to 11 deaf signers and 20 hearing non-signers. Behavioural data showed poorer and slower performance for both groups in Phonological and Orthographic conditions than in the Semantic condition, in line with depth-of-processing theory. An exclusive masking procedure revealed distinct sign-specific neural networks supporting working memory components at all three levels of processing. The overall pattern of sign-specific activations may reflect a relative intermodality difference in the relationship between phonology and semantics influencing working memory storage and processing.

Background Evidence-based practice has increasingly been recognized as a priority by professional physiotherapy organizations and influential researchers and clinicians in the field. Numerous studies in the past decade have documented that physiotherapists hold generally favorable attitudes to evidence-based practice and recognize the importance of using research to guide their clinical practice. Research has predominantly investigated barriers to research use. Less is known about the circumstances that actually support use of research by physiotherapists. This study explores the conditions at different system levels that physiotherapists in Sweden perceive to be supportive of their use of research in clinical practice. Methods Patients in Sweden do not need a referral from a physician to consult a physiotherapist and physiotherapists are entitled to choose and perform any assessment and treatment technique they find suitable for each patient. Eleven focus group interviews were conducted with 45 physiotherapists, each lasting between 90 and 110 minutes. An inductive approach was applied, using topics rather than questions to allow the participants to generate their own questions and pursue their own priorities within the framework of the aim. The data were analyzed using qualitative content analysis. Results Analysis of the data yielded nine favorable conditions at three system levels supporting the participant’s use of research in clinical practice: two at the individual level (attitudes and motivation concerning research use; research-related knowledge and skills), four at the workplace level (leadership support; organizational culture; research-related resources; knowledge exchange) and three at the extra-organizational level (evidence-based practice guidelines; external meetings, networks, and conferences; academic research and education). Conclusions Supportive conditions for physiotherapists’ use of research exist at multiple interdependent levels, including the individual, workplace, and extra-organizational levels. Research use in physiotherapy appears to be an interactive and interpretative social process that involves a great deal of interaction with various people, including colleagues and patients.
