A Systems Thinking Approach to Green Schools
The school facility is positioned to provide contextual cues for informal and formal learning in environmental education (EE). Evidence suggests that incorporating the school facility with EE also provides a context in which students can engage with environmental issues like waste management and energy conservation. Using the school building as a learning tool has been well documented and is supported as an instructional approach in Ontario’s public schools. The purpose of this study is to explore the interacting attributes of Ontario EcoSchools to identify themes supporting the integration of the school facility with EE. This qualitative study examines how this occurs within the context of whole school sustainability. This is achieved through a secondary data analysis of the results from 2017/2018 EcoSchool Platinum applications to determine how these schools are integrating the school facility with EE. Platinum certification allows high achieving schools to deepen their existing green school program. A school’s building and operations are important components in achieving school board policies for EE and sustainability while also supporting national and provincial climate change mitigation and sustainability objectives. The findings in this investigation highlight the themes, Formal/Curriculum Learning, Non-formal Learning, Building Attributes, Cross-Cutting and Partnerships within the school facility that is a sub-system functioning as a place where students are learning about environmental issues through direct and indirect engagement with their surroundings. Integrating the school facility with EE reflected non-linear approaches to EE where students were reflexive as they engaged in sustainable practice while co-creating their sense of place with the school facility
Length-weight relationship, condition factor and sex ratio of two chrysichthys species (pisces: claroteidae) of socio-economic importance from Kpong reservoir in Ghana
A total of 392 combined samples of Chrysichthys auratus and Chrysichthys nigrodigitatus was obtained from experimental and artisanal fishing from inshore and offshore areas of Kpong Reservoir. C. auratus and C. nigrodigitatus exhibited hyperallometric (b = 3.17–3.23) and hypoallometric (b = 2.79 - 2.91) growth patterns, respectively. Fluctuating monthly condition factor for males, females and combined sexes observed for the two species based on standard length and total length could be attributed to changes in feeding activity and, or degree of nourishment, food availability, gonadal activity, and season. However, based on total length, October and June were periods of the best physiological condition for C. auratus, while for C. nigrodigitatus, December was the least physiological period. There were significantly more females than males while differences in sex ratio were significant at 95 percent confidence interval (P = 1.354), indicating departure from the expected sex ratio of 1:1 for the two species. Regular assessment of biological, ecological and environmental characteristics of the species is recommended to provide the requisite information for sustainable management of the species for reservoir fishery development and food security

Potential fish yield and Physico-chemical characteristics of Weija reservoir in Ghana
The Weija Reservoir is an important resource for the production and supply of potable water, fish and irrigation services in Ghana. The study was undertaken to estimate the potential fish yield of Weija Reservoir to provide information for planning and management and to address the challenges of paucity of information on the potential fish yield of reservoirs in Ghana. Fish and water samples were collected monthly between March and December 2011 at Intake, Machigeni and Galilea sampling stations in the Weija Reservoir. Based on the physico-chemical parameters evaluated, the Weija Reservoir is adequate for fish survival, growth and production despite indications of low levels of organic contamination. Estimates of mean fish yield and potential fish yield for the three (3) stations based on morpho-edaphic index indicate that Machigeni has the highest yields followed by Intake and Galilea due to differences in anthropogenic activities, contamination and species richness. Monthly variations in potential fish yield and physico-chemical parameters follow similar pattern at all three sites with Machigeni recording the highest values and Intake the lowest. For the section of the reservoir sampled, the mean potential fish yield was 68.27 kg ha-1 while the mean fish yield was 229.45 t yr-1 giving indication of declining fish yield compared to the earlier life of the reservoir which is attributable to physico-chemical, environmental, biological and anthropogenic changes. For successful fisheries management, regular monitoring of the fish species as well as control of fish habitat and environmental degradation are recommended

Aspects of the fecundity of the black-chinned tilapia Sarotherodon melanotheron in the Fosu lagoon, Ghana
The black-chinned tilapia, Sarotherodon melanotheron (Pisces: Cichlidae), which dominated the Fosu Lagoon fishery, was exposed to pollution, siltation, fishing pressure, destructive fishing methods, and climate change. Samples of black-chinned tilapia were obtained with cast net, drag net and gill net, out of which 441 gravid specimen were randomly selected and dissected to remove eggs which were then counted. The absolute fecundity varied from 20 eggs to 370 eggs with a mean of 78 ± 33 eggs. Fish that had fecundity below and above the reported minimum of 200 eggs constituted 98.86 percent and 1.14 percent of the total sample, respectively, indicating that fecundity is below the minimum number of eggs the species is reportedly capable of producing. Positive, linear, weak and significant relationships were found between absolute fecundity and body parameters indicating that absolute fecundity is independent of body parameters, and could be influenced by biological, environmental, or anthropogenic factors. Condition factor ranged between 2.26 SL and 10.63 SL. Length at first maturity was 4.8 cm SL and 6.4 cm TL, respectively, confirming the precocious reproductive habit of the species. The size structure of the S. melanotheron population is dominated by small-sized fish of SL 7.0 – 7.9 cm (44.90 %) and 6.0 – 6.9 cm SL (32.65 %) ranges, which together accounted for 77.55 percent of the total sample. It is recommended that the fecundity and other reproductive parameters of the species be investigated during the dry and wet seasons in order to determine the reproductive potential and strategies for survival of the species
Water Quality of the Weija Reservoir after 28 Years of Impoundment
The water quality of the Weija Reservoir was assessed and the various sources of contaminants were identified in order to provide scientific basis for finding appropriate remedies to the contamination problems that may confront the Reservoir. Monthly
water samples were taken from three sampling stations in the Weija Reservoir and analysed for physico-chemical parameters in the laboratory. The mean pH values of the sampling sites were within the recommended range of 6.5–8.5 for potability and sustenance of aquatic life. The ionic dominance pattern observed was Na > Ca > Mg > K and HCO3 > Cl > SO4, indicating partial cationic characteristics of sea water and anionic characteristics intermediate between fresh water and sea water. Dissolved oxygen (DO) levels were 102.5%, 81.5% and 82.7% saturation for Weija Intake, Machigani and Galilea, respectively. Thus, the oxygen conditions in the Weija Reservoir were sufficient to support fish and other aquatic life. Maximum BOD level was 8.1 mg/l at Weija Intake. Compared with previous studies on the Weija Reservoir, results of the study show a slight increase in
nitrate, ammonia, sulphate and phosphate levels. Generally, the levels of nitrate, sulphate, phosphate, trace elements (e.g. manganese and iron) and BOD were moderately high. Anthropogenic activities, such as stone quarrying, dumping of domestic wastes, as well as run-offs from agricultural activities and the occurrence of algae, are some of the sources of contamination identified in the study. Tougher legislation, stricter enforcement of existing regulations, matching of non-technical and technosocial remedial measures and education are among the recommendations made for the protection of the Weija Reservoir.West African Journal of Applied Ecology Vol. 13 2008: pp. 125-13
Fisheries and limnology of two reservoirs in Northern Ghana
The fisheries and limnology of Bontanga and Libga reservoirs in northern Ghana were studied with the objective of generating information to support the development, management and sustainable use of their fisheries to enhance the socio-economic status of riparian communities. Using gill nets of various mesh sizes, fishes were sampled monthly and individually identified, weighed and measured for standard and total lengths. Water samples were taken monthly and analysed for physico-chemical parameters. In the Bontanga Reservoir, 21 species belonging to 18 genera and 10 families were encountered. Four families, namely Clariidae, Cichlidae, Cyprinidae and Clarotidae constituted almost 83% of the fishery while Clarias anguillaris, Auchenoglanis occidentalis, Barbus macrops and Sarotherodon galileus were the major species. In the Libga Reservoir, 36 species, representing 27 genera and 15 families, were obtained. Twofamilies, namely Mochokidae and Centropomidae constituted almost 67% of the fishery resources while Synodontis gambiensis and the Nile perch, Lates niloticus, were the dominant species. The fish diversity of the Bontanga Reservoir was lower than that of the Libga reservoir. Carnivorous fishes were dominant in Bontanga Reservoir while fishes offorage feeding habits were the major feeding group in Libga Reservoir. The forage-carnivore ratios of 1.60 and 2.12 for Bontanga and Libga reservoirs, respectively, suggest a suitable ecological balance between carnivorous fishes and their prey populations. The estimated potential fish yield per year for the Bontanga Reservoir (67 tons) was higher than thatof the Libga Reservoir (4.7 tons) mainly due to its larger size although the productivity per hectare for Libga Reservoir was slightly higher. Both reservoirs were well oxygenated all year-round with relatively high oxygen demanding substances and slightly acidic from June to October. The Bontanga Reservoir was characterized by a strikingly high ionic content. The nutrient level and the mean productivity of the Bontanga Reservoir were slightly lower than those of the Libga Reservoir
A marketing communications plan to increase brand aAwareness of Accents & Art
Applied project submitted to the Department of Business Administration, Ashesi University College, in partial fulfillment of Bachelor of Science degree in Business Administration, April 2017Accents & Art Limited (A&A), is a fully Ghanaian-owned company founded in May
2000 by Constance E. Swaniker. The company specializes in furnishings and décor made
primarily out of metal, with wood, glass, and cane accents.
The primary objective of this project was to identify a problem that Accents & Art faced,
and go through the necessary steps to find an appropriate solution for it.
Having been in operation for a little over 16 years, A&A has relied mainly on customer
referrals to gain business and new customers. This has led to them having relatively low
brand awareness thus making it difficult to attract new customers.
Qualitative research was used to find the appropriate and most effective means by which
A&A could reach potential clients. Findings from this were then used to craft a solution
suited to A&A and its problem. This solution was a marketing communications plan
based on the PASTA model which involves Problem Definition, Analyzing, Strategy,
Tactics and Action.
When implemented, this marketing communications plan will be able to help A&A
increase its brand awareness and thus be able to attract a wider range of new customers.Ashesi University Colleg
