Investigation of municipal solid waste management in GCC states

This thesis investigated the municipal solid waste management in GCC states. An investigation of the GCC municipal solid waste legislation's was conducted and compared and some comments and proposed changes were pointed. The main issue of municipal solid waste management in GCC states is the absence of regional co-operation on government level. Therefore recycling and composting that could have a major role in the enhancement of the environment in the GCC states were examined and several actions that could be taken by the GCC government were proposed. The government's role in helping to increase the participation of the public in waste management activities was discussed. A regional recycling scheme was investigated and proposed including some financial aspects. Composting facilities in GCC states were investigated and especially composting as an alternative in Kuwait. Some recommendations on composting were presented. Investigation of construction and demolition waste recycling opportunity in Kuwait was examined

Environmental Parasitology: intestinal helminth parasites of the siganid fish Siganus rivulatus as bioindicators for trace metal pollution in the Red Sea

Studies on host-parasite systems as bioindicators for monitoring trace metal pollution in marine environments are still scarce. Here, 11, 14 and 17 infrapopulations of Gyliauchen volubilis (Trematoda: Digenea), Procamallanus elatensis (Nematoda) and Sclerocollum rubrimaris (Acanthocephala), respectively, were collected from the fish Siganus rivulatus (Siganidae) in the Red Sea, from a chronically polluted small bay at Sharm El-Sheikh, South Sinai, Egypt. Water and sediment samples from the bay, tissue samples (intestines, liver, and muscle) from each fish, and samples from each parasite were taken for heavy metal analyses of cadmium and lead. Cadmium concentrations in intestines, liver and muscle of non-infected and infected fishes were much lower than those of lead, and both metal concentrations decreased in the order: liver > intestines > muscle. Cadmium and lead concentrations in the tissues of fishes infected with G. volubilis or P. elatensis were slightly lower than those in non-infected ones, while in the tissues of fishes infected with Sc. rubrimaris, they were much lower. Low concentrations of cadmium and lead in G. volubilis and P. elatensis are associated with their limited ability or capacity to accumulate trace metals. Therefore, bioconcentration factors corresponding to these species were relatively low, and both are herein considered as weak bioindicators. By contrast, high concentrations of cadmium and lead in S. rubrimaris are associated with its high ability to accumulate trace metals. Of the present three host–parasite systems, only the Siganus rivulatus–Sclerocollum rubrimaris system seems to be promising for biomonitoring of metal pollution in the Red Sea

Using strategy tools: an exploration of the selection, application, and outcomes of strategy tools among Kuwaiti non-profit executives

Critics of the traditional strategy schools of thought have called to approach strategy research from a different perspective (March 2006), pushing to address strategy with a ‘social eye’ as Whittington (1996; 2003) suggested. Orienting from a strategy-as-practice (S-as-P)perspective and utilizing the tools-in-use framework (Jarzabkowski & Kaplan,2015) as an analytical lens, this study explored how Kuwaiti practitioners used strategy tools in non-profit organizations. The focus on strategy tools guided the design and direction of the study, where the researcher examined how Kuwaiti practitioners use non-market strategy tools, specifically the AI3 model (Bach & Allen, 2010). This study employed an interpretive approach to observe how practitioners use the tool in their practical strategy work within their organizations. The researcher conducted three focus groups to understand how practitioners perceived and used strategy tools. She completed an additional session to observe how the practitioners interacted with the analytical tool in real-time. This study supplements previous work on strategy-as-practice (S-as-P) and strategy tools through the following theoretical contributions. Firstly, it added to the body of knowledge on 1) the identity and the role of the strategy practitioner, 2) the activities and processes of doing strategy, and 3) the tools and techniques used to perform the work in different contexts (Whittington, 2013; Jarzabkowski & Spee, 2009; Jarzabkowski & Kaplan, 2015). Secondly, it added to the Nonmarket Strategy body of knowledge by practically introducing and applying the concept within a unique business environment such as Kuwait. Lastly, it delineated issues that determined the effectiveness of strategy tools and explored how practitioners utilized them. When developing tools, the practical way of using strategic instruments and the needs of its practitioners are not always considered (Stenfors et al., 2004). These contributions to the body of knowledge also led to some practical implications. Firstly, it analysed how Kuwaiti executives perceived and conducted strategy work in general and how they perceived and conducted non-market strategy work within their respective organizations. Finally, the concept of how tool developers can create better fitting tools that consider the various ways and reasons for their use by executives in different contexts such as Kuwait since Western thought and languages dominate strategy tool design (Jarzabkowski & Kaplan, 2015; Cabantous & Gond, 2011; Feldman & March 1981; Langley, 1989)

Evaluation of DNA polymorphism in the Red Sea Epinephelus species using 12s rRNA and inter simple sequence repeats

1197-1205The true phylogenetic relation among Epinephelus species is under debate. The present investigation was designed for evaluation of DNA polymorphism in some Red sea Epinephelus species using 12s rRNA and Inter Simple Sequence repeats. DNA polymorphism values were detected and evaluated within all estimated fishes. Both applied techniques revealed that E. malabaricus is closely related to E. summana. The distance value between E. chlorostigma and E. areolatus is lower than the distance value between E. chlorostigma and E. radiatus. The Serranidae evolutionary variations were evaluated comparatively with other ray-finned fishes belonging to four fish genera (Carangidae, Labridae, Mugilidae and Cichlidae) based on 12s rRNA sequence variations (obtained from NCBI). The developed DNA markers were reliably branched in the evaluated fishes. More molecular investigations using more spatial and temporal fish samples should be carried out in the future for exploring the true Epinephelus species biodiversity in the Red sea
