Research with geriatric populations suggests high levels of clinical depression and greater financial and psychological costs of treatment in long-term care facilities with more restrictive care. Research on learned helplessness, a construct separate from depression, suggests learned helplessness and perceived control are useful theories for the study of elder depression, but the relationship between depression and learned helplessness in this population is not clear. This cross-sectional quantitative study examined the relationship between depression and learned helplessness by comparing residents over age 65 in less restrictive assisted living (n =42) versus those in more restrictive skilled nursing facilities (n =63). Data were collected using the Geriatric Depression Scale, the Helplessness subscale of the Cognitive Distortion Scales, and the Learned Helplessness and Instrumental Helplessness subscales of the Multi-Score Depression Inventory. Between-group ANOVA results confirmed a higher level of depression and state learned helplessness, but not trait learned helplessness, in restrictive skilled nursing residents when compared to those in less restrictive assisted living residents. There were positive correlations between learned helplessness, instrumental helplessness, and depression regardless of level of nursing care, and a positive correlation between perceived control and depression regardless of level of facility care. Identifying state learned helplessness and depression in long-term, restrictive care facilities can promote positive social change through increased awareness, intervention, and treatment to improve individual quality of life and maximize internalization of perceived control of the decision making process for elders.

Studien fokuserar på en praktisk tillämpning av lärdomar från erfarenheter, så kallade lessonslearned, inom kontexten sprintretrospektiv. Genom att studera utvecklingsteam på en svenskmyndighet som använder sig av det agila ramverket Scrum, är syftet att bidra till en utökadförståelse för hur myndighetens arbete med lärande genom sprintretrospektiv sker, samt attföreslå förbättringar. Empiri inhämtas genom en kvalitativ fallstudie och relateras till teorierinom knowledge management och organizational learning, varefter en tankemodell, lessonslearned-tratten, utvecklas. Lessons learned-tratten visar hur sprintretrospektivets struktur kanvara ett stöd i utvecklingsteamets lärande. Den gör detta genom att tydliggöra moment därteammedlemmarna delar med sig av erfarenheter, formaliserar och analyserar dem, beslutarom åtgärder samt möjliggör återkoppling genom en nedskriven åtgärdslista.

In an effort to free up valuable storage space, an obsolete dual tube furnace facility was repurposed to process legacy and newly generated reaction by-products for reuse and/or evaluation. These materials consist of magnesium oxide and unreacted chemicals including small amounts of uranium. They will be converted to their safest form. The repurposing of the facility was not a simple undertaking as all of the utilities with the exception of electricity were disconnected from the facility and the furnaces were more than 50 years old. A 2-part project consisting of a construction phase and transition to operations phase was initiated to accomplish the task. Because funding was done in a piecemeal fashion, the dynamics of restarting the facility was accomplished using creative project management. Lessons learned will provide invaluable information for future sustainability endeavors that require the renovation of an out-service facility to meet current and future needs.

Organisms can form safety associations with cues that predict the absence of an aversive event. This cognitive process, learned safety, is important for modulating emotional processing, as safety cues can decrease fear in the presence of previously learned danger cues. Further, there are clinical implications in understanding learned safety, as individuals with PTSD present with deficits in learned safety. Additionally, there is a well established relationship between smoking and PTSD. The link between smoking and PTSD is unclear, however one possibility is that nicotine-associated changes in cognition could facilitate PTSD symptoms, particularly by disrupting are altering learned safety. Considering that nicotine has been shown to modulate associative learning, including hippocampus-dependent forms of fear learning, we hypothesized that nicotine administration could cause maladaptive associative learning to occur, leading to altered safety learning. In the present study, mice were administered acute nicotine and trained and tested in two forms of cued safety learning, explicitly unpaired and backwards trace conditioning. To test for conditioned inhibition of fear by safety cues we performed summation testing. Summation testing indicated that acute nicotine did not impact unpaired learned safety, but did disrupt backwards trace conditioned safety. Additionally, chronic nicotine was found to have no effect on backwards trace conditioned safety, suggesting the development of tolerance. Importantly, on a separate test in which the backwards trace conditioned stimulus was presented alone in a novel context, acute nicotine administration was found to facilitate a fear association with the backwards trace conditioned stimulus. Therefore, acute nicotine prevented backwards trace conditioned safety, by facilitating the formation of a maladaptive fear association. Finally, we found that infusion of nicotine into the dorsal hippocampus and medial prefrontal cortex resulted in similar maladaptive behavioral patterns in summation testing. These findings are discussed with respect to how nicotine can alter cognition and the role alterations in cognition may play PTSD. / Psychology

The goal of this study was to investigate if participation in collaborative professional development workshops - on learned helplessness, self-efficacy, and metacognition - would impact teachers' beliefs in their capacity to address students' helplessness. The underlying assumption was that, with deeper understanding of the theoretical background upon which instructional practices should be constructed, teachers would develop a stronger belief that, through their pedagogical practices, they could impact students' individual learning outcomes as well as the classroom environment. In order to achieve this endeavor, an eight-week intervention was conducted in a low-achieving and low SES public school in Rio de Janeiro, Brazil. The study's design, development, implementation, and evaluation were oriented by guidelines derived from the formative and design experiment methodology. The study benefited from quantitative and qualitative data collection and analysis methods. Triangulation of data showed strong consistency between quantitative and qualitative findings. After the intervention, participating teachers acknowledged implementing the theories in their classrooms. Reported impacts included (a) strengthened teachers' beliefs about their capacity for effective teaching in this school environment; (b) increases in teachers' instructional efficacy and metacognitive abilities; (c) increased capacity to exercise reflective practice through evidence- based self-evaluations; (d) increased capacity to create comprehensive lesson plans including the Nine Events of Instruction (Gagne, 1985), the MUSIC Model of Academic Motivation (Jones, 2009), and metacognitive strategies (Schraw, 1998). As teachers implemented the strategies in their classes, they reported positive impacts on the students' interests, attitudes towards classroom activities, and efforts to achieve. / Ph. D.

Accelerated Bridge Construction, also known as ABC, is a methodology that seeks to improve project development of bridges by reducing the overall project schedule and the impact on the traveling public by implementing innovative technologies and strategies in any phase of project development. However, ABC may incur additional direct costs for the project and some risks are associated because of the accelerated constraints implied in this methodology. On the positive side, the opportunity costs and reductions of traffic disruptions costs may overcome the additional costs associated with ABC. Decision-making methodologies for assessment of ABC as an alternative to traditional construction are of great interest for project developers. The topics of research about ABC are diverse but focus mainly on the means and methods, technical aspects, applications, innovations, and decision-making of ABC. Decision-making is of great concern for project developers, especially government organizations, to sustain project goals of serviceability and to validate the additional expenditures in a project. In addition, project developers improve their decisions and project outcomes by reviewing success and failure cases for completed projects in the past. This study seeks to improve the decision-making processes in ABC by finding a more direct correlation of projects to compare by means of a categorization of these ABC projects. Smaller groups in this categorization will help narrow the scope of the characteristics of the projects to consider and to find more relevant lessons learned from the smaller groups of the categorization. To develop the categorization in this study, the data source used is the completed ABC projects database from the Federal Highway Administration (FHWA). The statistical categorization methodology for this study is the Agglomerate Hierarchy Clustering which developed a determined number of cluster based on the closeness among data parameters with "n" number of dimensions of analysis. The number of dimensions for the analysis in this study was established as 13 parameters collected from the database and these were considered critical decision-making parameters and consequential parameters to reflect project decisions and consequences of those decisions. The results of this study rendered 3 categories, and into these categories, 5 sub-categories were distributed according to the same analysis developed. The sub-categories show similarities between the projects according to the parameters established, so the sub-categories help narrow the scope of projects for project developers. As a complement to the categorization, a project matching tool for external projects was also developed to help decision-makers to test their projects according to the analysis in this study and also help developers narrow their review of cases in search for lessons learned. Uses of this study include the prediction of information of parameters according to the variables and ranges in this categorization, and the narrowing of study cases to review. Stakeholders interested can be government organizations seeking to establish the viability of an ABC project, or to improve their project outcomes at any stage of development. Other stakeholders can be designers and contractors that also need to improve their projects at any stage of development. / Master of Science / Accelerated Bridge Construction (ABC) reduces construction time and diminishes traffic disruption by applying strategies and innovations to the way bridges are designed and constructed. However, it implies additional initial costs that need to be justified. Project developers need to evaluate their projects to make decisions to assure the best execution and outcomes. The review of lessons learned from previous bridge projects has been one of the sources that developers have found to find strategies and tips to implement best practices or to avoid mistakes during planning and construction of new bridge projects. This study relies on the lessons learned compiled on the completed ABC project database from the federal transportation authority, the Federal Highway Administration (FHWA), in order to help developers, narrow the scope of projects to be reviewed and find more relevant cases to compare their projects. This scope includes the development of a categorization or a structured hierarchy of completed ABC projects with the FHWA database by applying a statistical analysis and a validation procedure. The results of this study rendered a categorization with 3 categories and 5 subcategories, each with its definition of parameters, which highlight the similarities among projects in the same groups and the differences among different categories. In addition, a framework was developed to match external projects with the categorization in this study to help project developers narrow the projects to review, or even predict missing information according to the parameters in this study. These results may help decision-makers better inform their decisions and support the research in the field of study.
