The potential for Gracilaria polyculture at Jacobs Bay Sea Products Pty

This report investigates the potential for the culture of G. gracilis, an indigenous red alga, into the west coast mariculture farm Jacobs Bay Sea Products Pty. Various methods for cultivating Gracilaria as well as environmental parameters, which influence growth of Gracilaria, are disltussed below. From these optimal conditions for the polycultivation of G. gracilis are determined. Cultivation can take place either, in open waters, or on land. Open water systems are generally less intensive than land based operations. Open water systems can be either bottom planted or suspended. Suspended cultivation has the advantage of maintaining the plant thalli in optimal light intensities. Land based systems can make use of ponds, raceways or tanks. Tanks and raceways are more productive than ponds, but require higher flow rates and regulated nutrient regimes

The response of mobile intertidal invertebrates to subsistence harvesting in Northern KwaZulu-Natal

The Response of mobile intertidal invertebrates to subsistence harvesting in Northern KwaZulu Natal was investigated. Spatial scale comparisons were made between as well as within harvested and non-harvested locations. The difference in three population variables was investigated: i) abundance of species groups. ii) size structure of each organism and iii) community structure of mobile organisms. Abundance analysis revealed no significant difference between harvested and no harvested regimes for most species' groups, excepting Snails and Chitons. Snails were more abundant und chitons less abundant at harvested sites. A significant difference.... between locations was however noted, for all species groups, suggesting that variation in abundance within is more prominent than between harvesting regimes. Size stmcturc analysis revealed significantly larger sizes for most spec1cs at non harvested locations, with only Morula gm1111/u111 and Scutellastm exusw showing u significantly larger size structure at non-harvested locations. Community structure analysis revealed no clear distinction between or wi1hin harvested locations. A decrease in size structure with no co1Tespondi11g density effect may be a function of the preference of harvesters for larger individuals, thereby favouringjuveaile populations. The possibility also exists that density effects have been masked due to the use of size instead of biomass data. Converting to size data to biomass, using wet mass versus size regressions, may be a more appropriate analysis method. The observed differences in community structure between as well ru; within loi:-ations indicates that the intertidal communities are inl1erintly hcterogenous in this area. ln order 10 determine the irnpacr of exploitation. spatial scale comparisons between harvesting regimes thus ideall y need to be conducted to each location. [n this study there was also a lack of representative control sites, us unharvested locatio11s are impacted by fisherman and tourists. A possible strategy would be to demarcate "110-go" areas in harvested and non-harvested areas, to serve as both controls and provide broodi11g stocks for adjacent ledges. It is however recommended that more research emphasis be placed on U1e user in evaluating the effects ofhurmtn tmpact on intertidal resource

An investigation of selected academic and nonacademic predictor variables of academic performance of student-athletes at Louisiana State University

This study investigated the effects of selected predictor variables of academic achievement on the academic performance of student-athletes at Louisiana State University. This study attempted to identify cognitive and noncognitive variables that might explain the variance in the cumulative college grade point average (GPA)among student-athletes at LSU enrolled during the 2003-04 academic year. Cognitive variables included ACT composite score, high school GPA, and cumulative college GPA. Noncognitive variables included positive self-concept, support of academic plans, and community involvement. In addition, data were collected for two sport variables--type of sport participation (revenue and non-revenue generating sports) and time spent on sport (in hours per week). These data were analyzed using a stepwise regression method for student-athletes as a group, as well as by subgroups of gender, race, and academic classification level (freshman, upperclassmen). In addition, follow-up interviews were done with selected student-athletes to provide insight into the experiences that student-athletes encountered as a result of their dual roles as students and student-athletes. The results of this study indicated that high school GPA, ACT composite score, gender, and academic classification level accounted for 55 percent of the variance in student-athletes\u27 cumulative college GPA. High school GPA was the most effective single predictor variable of student-athletes\u27 cumulative college GPA. In subgroup regression analyses, a different combination of cognitive and noncognitive variables explained most of the variance for each subgroup. Time spent on sport was significant in regression equations for whites, males, and upperclassmen student-athletes. Type of sport participation was significant for black and all freshman student-athletes. Support of academic plans was significant for all female and black student-athletes. The results of this study suggest that, in addition to the cognitive variables, the noncognitive variables accounted for additional variance in college cumulative GPA in the subgroup analyses. Moreover, student-athletes identified time constraints, feeling fatigued, and financial concerns as challenges encountered in their dual roles as students and student-athletes. These various experiences of student-athletes should be considered when developing academic support strategies designed to improve their academic performance

The Canengusian Connection: The Kaleidoscope of Tort Theory

In the course of our teaching and research, we uncovered a recent decision of the Supreme Court of Canengus. The judgment in Allan v. Derek was handed down on 1st April, 1984. We reproduce it here in the hope that it will be of some interest to tort lawyers and legal scholars generally

Advance care planning documentation strategies; goals-of-care as an alternative to not-for-resuscitation in medical and oncology patients. A pre-post controlled study on quantifiable outcomes

Background: Health services in Tasmania, Victoria and now Western Australia are changing to goals-of-care (GOC) advance care planning (ACP) documentation strategies. Aim: To compare the clinical impact of two different health department-sanctioned ACP documentation strategies. Methods: A non-blinded, pre–post, controlled study over two corresponding 6-month periods in 2016 and 2017 comparing the current discretional not-for-resuscitation (NFR) with a new, inclusive GOC strategy in two medical/oncology wards at a large private hospital. Main outcomes were the uptake of ACP forms per hospitalisation and the timing between hospital admission, ACP form completion and in-patient death. Secondary outcomes included utilisation of the rapid response team (RRT), palliative and critical care services. Results: In total, 650 NFR and 653 GOC patients underwent 1885 admissions (mean Charlson Comorbidity Index = 3.7). GOC patients had a higher uptake of ACP documentation (346 vs 150 ACP forms per 1000 admissions, P \u3c 0.0001) and a higher proportion of ACP forms completed within the first 48 h of admission (58 vs 39%, P = 0.0002) but a higher incidence of altering the initial ACP level of care (P = 0.003). All other measures, including ACP documentation within 48 h of death (P = 0.50), activation of RRT (P = 0.73) and admission to critical (P = 0.62) or palliative (P = 0.81) care services, remained similar. GOC documentation was often incomplete, with most sub-sections left blank between 74 and 87% of occasions. Conclusion: Despite an increased uptake of the GOC form, overall use remained low, written completion was poor, and most quantitative outcomes remained statistically unchanged. Further research is required before a wider GOC implementation can be supported in Australia’s healthcare systems

The Durban Climate Change Strategy: Lessons learnt from the 2021 strategy review and implementation plan

Urban local governments are increasingly developing climate change adaptation plans. However, there is limited literature on climate change adaptation experiences of African cities, particularly with regard to moving from strategy development to implementation. This continues to hamper efforts to understand and guide city climate change actions on the continent. This article helps address this gap by providing critical insights into the opportunities and challenges experienced, and the solutions found in the process of developing and implementing the Durban Climate Change Strategy (DCCS) in the City of Durban, South Africa. The initial 2015 DCCS was reviewed in 2020/2021, and an analysis of the process and its outcomes provide useful focus areas that could guide other cities across the Global South and beyond for implementing climate change strategies. Based on these focus areas, the article demonstrates that there are considerable governance and other barriers to this process that span multiple scales, but also many opportunities such as good organisation, ongoing support across multiple departments and scales, and perseverance that can be harnessed. The findings have significant practical and policy implications for developing and implementing urban climate strategies and provide important conceptual insights for building transformative resilience in challenging governance contexts
