Thesis advisor: Henry Braun / The Next Generation Science Standards propose a multidimensional model of science learning, comprised of Core Disciplinary Ideas, Science and Engineering Practices, and Crosscutting Concepts (NGSS Lead States, 2013). Accordingly, there is a need for student assessment aligned with the new standards. Creating assessments that validly and reliably measure multidimensional science ability is a challenge for the measurement community (Pellegrino, et al., 2014). Multidimensional assessment tasks may need to go beyond typical item designs of standalone multiple-choice and short-answer items. Furthermore, scoring and modeling of student performance should account for the multidimensionality of the construct. This research contributes to knowledge about best practices for multidimensional science assessment by exploring three areas of interest: 1) item design, 2) scoring rubrics, and 3) measurement models. This study investigated multidimensional scaffolding and response format by comparing alternative item designs on an elementary assessment of matter. Item variations had a different number of item prompts and/or response formats. Observations about student cognition and performance were collected during cognitive interviews and a pilot test. Items were scored using a holistic rubric and a multidimensional rubric, and interrater agreement was examined. Assessment data was scaled with multidimensional scores and holistic scores, using unidimensional and multidimensional Rasch models, and model-data fit was compared. Results showed that scaffolding is associated with more thorough responses, especially among low ability students. Students tended to utilize different cognitive processes to respond to selected-response items and constructed-response items, and were more likely to respond to selected-response arguments. Interrater agreement was highest when the structure of the item aligned with the structure of the scoring rubric. Holistic scores provided similar reliability and precision as multidimensional scores, but item and person fit was poorer. Multidimensional subscales had lower reliability, less precise student estimates than the unidimensional model, and interdimensional correlations were high. However, the multidimensional rubric and model provide nuanced information about student performance and better fit to the response data. Recommendations about optimal combinations of scaffolding, rubric, and measurement models are made for teachers, policymakers, and researchers. / Thesis (PhD) — Boston College, 2018. / Submitted to: Boston College.

Depression is heterogeneous, however, depression measures conceptualize it as homogeneous. To help fulfill NIMH's strategic plan to focus on components of depression, this study analyzed the psychometrics of factor-based subscales in the BDI-II, CES-D, IDAS, and IDS. CCA was also used to explore redundancy across measures. Using a diverse sample of symptomatic undergraduates, this study found the IDAS to be the best measure, with complete DSM-IV symptom coverage and psychometrically sound subscales. The other measures did not have consistent subscales or coverage of symptoms. Furthermore, CCA revealed low levels of redundancy across measures. These results serve to disabuse the field of a perception that different measures of equivalently measure depression. Conversion tables were provided to empirically compare scores from different measures.

In light of collated research linking temperament traits and executive performance, the aim of this study is to explore, in a large non-clinical sample, the differences in executive performance profiles among participants with different intensities of the trait Novelty Seeking (NS). A further aim is to establish which facets of NS contribute to these differences. The NS temperament dimension and its subscales were operationalised as scores on the Temperament and Character Inventory (TCI), which is based on the psychobiological theory of personality. The University of Pennsylvania Computerised Neuropsychological Test Battery (PennCNP) of executive functioning (EF) and abstract reasoning was used to measure participants’ neuropsychological EF. The total sample of participants (n= 461) was divided into high NS (n= 216) and low NS (n= 245) groups to investigate any significant differences between them. Further analysis was then conducted in order to analyse the relationship between the NS scale, the four subscales (Exploratory Excitability, Impulsiveness, Extravagance, and Disorderliness), and performance in executive tasks. The findings of this study indicated significant differences between groups with different intensities of NS, with the high NS group functioning notably better in performance and reaction time. Furthermore, this study showed that facets of NS, such as impulsiveness was a significant contributor to EF performance outcomes. / Dissertation (MA)--University of Pretoria, 2013. / Psychology / unrestricted

Abstract This cross-sectional survey study investigated middle and high school administrative team members’ leadership classifications and perceptions of secondary principals’ leadership actions and behaviors in the context of change and to what extent these perceptions are gender specific. In addition to gender, the study also examined the impact of race/ethnicity, age, campus level, length of employment in the district, length of time working with the principal, and closeness to the principals on leadership actions and behaviors. The results of the study are intended to highlight the importance and value of feminine-inspired leadership approaches and administrative team members’ perspectives of leadership in managing and leading the change process. The study targeted the leadership actions and behaviors of 39 middle school and 28 high school principals assigned to traditional secondary schools in the southwestern United States. Administrative team members’ perceptions of secondary school principals’ approaches to leadership served as the basis for the study, which investigated whether administrative team members perceived principals’ leadership actions or behaviors in a change context to be gender specific. Male and female administrative team members (n=210) were surveyed using the Leader Behavior Description Questionnaire (LBDQ), Form XII – fourth revision (Ohio State University, 1962). Based on survey results, secondary principals were classified as dynamic, considerate, passive, and structured leaders as rated by administrative team members using the LBDQ. The results of the study revealed that gender and school level of administrative team members did not influence the classification of secondary principals as dynamic, considerate, passive, or structured leaders. The ratings of those principals perceived as dynamic were statistically significantly higher than those of principals as passive and structured leaders. Out of 62 secondary principals, administrative team members classified principals as follows: dynamic leaders 63% (n=39), considerate leaders 5% (n=3), passive leaders 16% (n=10) and structured leaders 16% (n=10). Additionally, dynamic leaders received a statistically significant higher rating of closeness to principal when compared to passive and structured leaders. The findings of the study, which illuminate the perspectives of administrative team members with regard to secondary school principals, have implications for informing research on school leadership as well as educational leadership practices.

Social comparison influences well-being, especially during psychological threat. Social comparison outcomes have been theorized to depend on motivation, frequency, contrast versus identification, with a better- versus worse-off other. To reduce this complexity in the theory, 94 senior-housing residents were interviewed and cluster analysis was conducted. Four clusters emerged. Half the interviewees formed a cluster using only adaptive social comparison methods. Adaptives were contrasted with a cluster of indiscriminate comparers, a cluster striving for improvement, and a cluster of participants disagreeing with most questions. Clusters differed especially in patterns of downward identification, upward and downward contrast. Self-evaluation and uncertainty-reduction also differed between clusters; self-enhancement and self-improvement motivations did not. Cluster membership had no direct effect on well-being, but moderation analysis demonstrated threat-buffering of high neuroticism in the adaptive cluster. The benefits were not due to self-esteem or educational level. By separating individuals rather than behaviors, cluster analysis provides a fresh perspective.

The content of this work was to carry out construction-technical survey of timber structures of the existing building in order to design an appropriate procedure for their reconstruction. The survey showed construction in an unsatisfactory to disrepair, so further work also includes the static calculation of new structures proposed instead of the current. Timber structure in the building has form of staircase, roof and ceiling construction. Newly designed the following types of stairs and roof trusses from which the lower belts are used as ceiling beams. The new proposal also includes possible roofing, roofing options, developed one of them. The work also includes drawings, bill of materials and cost estimate staircase structure and truss. Specialization in the field of civil engineering is represented by drawings of the new truss and passport (view of current state) whole object on parcel ST.74 / 1, land Tišnov (okr.Brno-venkov), the content of which was the basis for this work.
