Material effects on strawbale wall seismic capacity
Strawbale construction is a sustainable, viable alternative to conventional building practices. As a newly introduced appendix to the International Residential Code (IRC), the strawbale construction requirements may benefit from further evaluation and possible refinement. Such evaluation and refinement may lead towards code change proposals that will improve the provisions and make strawbale construction safer and more accessible to the general public. This seismic test series addressed the effect of mesh wire type on ductility and the validity of the existing wall slenderness limits. The tests focused on slender walls dominated by flexural deformations. Welded wire mesh wall performed better than the woven wire mesh wall of the same detailing, yet fell short of expected values. Slenderness must continue to be analyzed as the results of a wall using 14” bales were impacted by bale irregularity. The additional tests done as part of this thesis, including vertical load tests and materials testing, added to the understanding of strawbale construction performance and expanded the corpus of strawbale wall test data. All tested walls performed satisfactorily under vertical loading in post-seismic conditions. The purpose of this test series was to validate and potentially suggest improvements to the building code provisions to enhance the prevalence and safety of strawbale construction
Monitoring first year Maori students enrolled in selected Faculty of Arts and Social Sciences courses: A report prepared for the Dean of the Faculty of Arts and Social Sciences
Monitoring first year Maori Students Enrolled in Selected Faculty of Arts andSocial Sciences Courses. The total number of Maori students targeted by this project was 182, representing 93% of the total number of Maori students enrolled in Semester B level one courses. The majority of students participating in this initiative were first year students, although a small number of students taking 100 level courses were second, third or graduate year students. 11 Student views on the monitoring and support initiative Students were provided with the opportunity to comment on the monitoring and support initiative. All students contacted (49) recommended that this intervention continue for future first year Maori students enrolled in FASS
Exploring The Barriers Colleges Face Implementing Positive Psychology Interventions To Reduce Depression, Anxiety, Or Stress In College Students
The purpose of this qualitative collective case study was to understand the barriers that colleges face implementing positive psychology interventions (PPIs) to reduce depression, anxiety, or stress (DAS) in college students. The problem was the lack of utilizing PPIs to reduce DAS in college students, despite increased reports of symptoms among this population. Several research studies have supported the use of PPIs to reduce. DAS in college students. However, no prior research was identified regarding barriers to initiating these interventions. The three research questions that guided this study were fueled by previous empirical studies that revealed three barriers to implementing sustainable mental health programs on college campuses. Funding, knowledge, and structure barriers were identified in this study. This qualitative research methodology approach involved 11 participants. The participants were selected using purposeful sampling methods that pinpointed the specific population of individuals required for the study. The setting for this study was 4-year colleges/universities on the U.S. East Coast. The states represented were North Carolina, South Carolina, Virginia, Maryland, and Pennsylvania. Multiple sources of data collection were utilized, including in-depth interviews, a focus group, and document analysis. This study identified specific barriers, such as funding barriers, -100% knowledge barriers regarding poor access to information, - 92%, and structural barriers associated to space and other constraints, -80%. The implications of abolishing the identified barriers will increase PPI use and reduce DAS
Evaluating the effectiveness of rangeland resting initiatives in communal grazing systems in South Africa
In South Africa, rangeland environments provide ecosystem services upon which many broader natural processes and millions of livelihoods depend. Against a background of environmental degradation and widespread poverty, trade-offs between different services must be carefully managed. 17% of South African rangeland is held under communal tenure, bringing unique management challenges. This thesis investigates the efficacy of Conservation Agreements (CAs) - an example of a Payments for Ecosystems Services approach - in achieving positive environmental and social outcomes within three communities in the Mvenyane region of Eastern Cape, South Africa. It seeks to establish whether areas of rangeland in these communities were successfully rested, a key tenet of these agreements. Biomass sampled from designated rested areas was compared against samples from exclosures within these rested areas. Focus groups (FG) were also conducted with local signatory institutions known as Grazing Associations (GAs) to identify factors contributing to in/effective resting. The findings show that rangeland was not effectively rested in any of the communities studied. Insights from the New Institutionalist paradigm and the broader literature were used to analyse data from focus groups and a household survey. This indicated inadequate institutional capacity to deliver management strategies required to satisfy the terms of the CAs, and limitations in the pro-social outcomes the CAs were designed to provide. In particular, the design of CAs contributed to the exclusion of marginalised groups from GAs. More broadly, a dichotomy was revealed between the market-based approach underpinning the CA arrangements, and the priorities of many rangeland users. Further research into reasons for non-participation in GAs, and into other local institutions of power, is suggested, alongside key policy recommendations. <br/
