Vitellogenin in Pimephales promelas was used to assess estrogenicity of a local municipal effluent. Vitellogenin induction in male P. promelas increased in frequency and magnitude with increased exposure duration and was greater ("=0.05) than controls after 2 and 3 weeks of exposure. The level of vitellogenesis induced by effluent exposure was high compared to similar studies. A spring season evaluation followed. Biomarkers in P. promelas were used to assess the efficacy of a treatment wetland to remove toxicity and estrogenicity in final treated wastewater effluent. Comparisons were made with an effluent dominated stream and laboratory controls. Vitellogenin, GSIs (gonado-somatic indices), HSIs (hepato-somatic indices) and secondary sexual characteristics were biomarkers used in P. promelas models to assess aqueous estrogenicity. Biological indicators used to assess general fish health included hematocrit and condition factors. The estrogenic nature of the effluent was screened, concurrent with fish exposure, with GC/MS analysis for target estrogenic compounds including: 17-b estradiol, estrone, ethynylestradiol, Bisphenol A, nonylphenolic compounds, phthalates, and DDT. Plasma vitellogenin measured in P. promelas was significantly elevated (p < 0.0001) at the inflow site of the wetland and stream sites. GSIs for these exposures were less (a=0.001) at the wetland inflow site. At wetland sites closest to the inflow, secondary sexual charateristics, tubercle numbers and fat pad thickness, were less (a=0.0001). Hematocrit and condition factors were less (a=0.001) at sites closer to the wetland inflow. Seasonal variation was examined by repeating the effluent characterization in summer. Additionally, summer testing included exposure to an effluent dilution series. Fish condition heavily influenced interpretation of the results. Pre-acclimation exposure to spawning stresses may have altered many of the biological markers measured. Results are discussed relative to fish health and pre-exposure environment. Toxicity assessed with P. promelas biomarkers was compared with Ceriodaphnia dubia and Vibrio fischeri toxicty tests on this effluent. Biomarkers of fish health were somewhat less sensitive than C. dubia test endpoints, but more sensitive than V. fisheri.

This study's aim was to investigate the strength of contextual aspects' influences on environmentally ethical behaviour (EEB). A survey method with a selfadministered questionnaire was used and a cross-section of the Muslim male population of New Zealand was taken. The qualitative interviews and email questionnaires were also utilised to further explain the survey results. The linear regression analyses show correlations between contextual aspects (i.e., social, religious, economic, political, and demographic) and EEB (pre-cycling, re-use and recycling). Results indicate that the contextual aspects are influential on EEB in many ways and degrees. A model describing the relationship was developed. The economic aspect statistically significantly related to EEB the strongest. The qualitative interview and email questionnaire data support the findings of the survey. The relationship was positive, meaning that the more the consumers were influenced by the economic aspect to behave in an environmentally ethical way, the more they were likely to perform EEB. Compared to the economic aspect, white collar workers, number of household occupant, work involvement with the environment, type of house, and age had a weaker statistically significant relationship with EEB. The relationships were positive, meaning that the better the consumers' occupation (i.e., white collar workers), the more household member they had (i.e., 4 and above), the higher their level of work involvement with the environment, and the better their dwelling (i.e., bungalow or semi-detached houses), the more they were likely to perform EEB. However, the relationship between age and EEB was negative, meaning that the younger the consumers the more they were likely to perform EEB. However, the results of this study, from both the survey and the interview methods, indicate that demographic characteristics were not as important as the contextual aspects, particularly the economic aspect, in understanding consumers' EEB. This study shows that the economic aspect was very important in understanding consumers' EEB compared to the other contextual aspects even the political aspect was statistically significantly related to EEB via the economic aspect. Thus, the economic aspect should be used optimally by public and private sector managers to promote EEB.

Copper hydroxide-treated surfaces are commonly used to control roots in horticultural production systems, although the particulars of Cu movement from the treated surface are largely unknown. The rate and temporal pattern of Cu mobility from in-ground Cu-treated growing baskets, and the fate of this Cu, was studied. In a field experiment involving Acer platanoides, an alternative Cu formulation consisting of Cu metal powder was determined to move slightly more slowly from the basket fabric than Cu(OH)2 over the first season while providing adequate root control. Addition of Glomus intraradices inoculum to the basket system increased the mobility of Cu metal and had no effect on Cu(OH) 2. This suggests that VAM fungi can actively solubilize Cu metal. These results also confirm that the chemistry of the Cu, possibly in addition to the chemistry of the resin, determines Cu movement from the treated surface. The fate of Cu from in-ground baskets planted with Acer jinnala was elucidated in a second field experiment. After one field season, the majority of Cu initially on the basket fabric had been deposited in the soil both in- and outside the basket. While Cu recovered in leachate represented only a tiny fraction of basket Cu, the concentration of Cu in leachate exceeded acceptable limits in the majority of samples. This indicates that the use of Cu(OH) 2-treated baskets in the field may have a negative impact on groundwater quality.

La recherche réalisée dans le cadre de notre thèse vise à étudier les conditions de la construction de l’énonciation de l’homosexualité masculine en proposant une analyse comparative des époques récentes. Ce qui nous intéresse alors, ce sont ainsi les supports de communication (espaces médiatiques et technologies numériques) et les formes de prise de parole. Notre thèse s’organise autour de trois parties. La première partie consiste à mettre en avant le contexte et les caractéristiques de l’énonciation de l’homosexualité. Nous proposons de revenir sur les travaux de Michel Foucault (au travers de son ouvrage La volonté de savoir) afin d’étudier la mise en discours du sexe et ainsi la construction des sexualités. Cela nous amène ainsi à identifier, à travers les époques, les variations de l’énonciation allant d’une logique du secret à une logique revendicative (voire subversive), mais également à étudier la place et les différentes conceptions du coming out. Dans une deuxième partie, nous mettons en avant les différents héritages des formes d’énonciation. Pour cela, nous évoquons les différentes manières de représenter l’homosexualité masculine au cinéma, à la télévision et dans les web séries, à travers une approche linéaire et généalogique des années 1930 à aujourd’hui. Puis, nous revenons également sur les pratiques de la drague homosexuelle selon les lieux ouverts et fermés ; ce qui nous amène alors à nous interroger sur l’existence d’une libération des formes expressives. Enfin, à partir de l’analyse de l’application mobile Grindr, nous proposons dans une troisième et dernière partie, d’identifier les différentes figures du dragueur et ses itinérances à l’heure de la géolocalisation. Nous abordons plus précisément le statut et le rapport à l’image, l’identification des différents types de regards qui s’organisent dans l’application, et les enjeux et les conséquences dans le cadre de l’énonciation de l’homosexualité
The research conducted as part of our thesis aims at looking into the construction of the utterance of male homosexuality putting forward comparative analysis of recent times. Our concern is communication medium (media environment and digital technologies) as well as the different forms of speaking. Our thesis is organized around three parts. The first part consists in highlighting the context and the characteristics about telling homosexuality. We will suggest to revisit Michel Foucault’s work (through his work La volonté de savoir – The will to know) in order to study the implementation of the discourse about sex and then the construction of sexualities. It is also a question of identifying the variations of the self-ascription from the logic of secret to a protest or even subversive form of logic through different times, with the evocation of the place and the different aspects of “coming out”. In a second part, we will explain the different legacies of the ways to express homosexuality. We will then mention the different ways to represent male homosexuality in films, television and in web series through a linear and genealogical basis from the 1930’s until today. We will next review the practice of cruising according to open or closed areas: this will lead us to question the existence of the liberation of expressive forms. Finally, in a third and last part, we will put forward, from the mobile phone application Grindr, the identification of the different features of the cruiser as well as his roaming in a geo-tracking world. We will discuss more precisely the status and the relationship to image, the identification of the different types of views organized through the applications and the stakes and consequences as part of the utterance of homosexuality

Dans ce travail de thèse, on s'intéresse é l'emploi de techniques de traitement de signal de systèmes de communication MIMO (Multiple Input Multiple Output) pour des applications aux réseaux de capteurs sans fil. Les contraintes énergétiques de cette classe de réseau font appel à des topologies particulières et le réseau peut être perçu comme étant un ensemble de grappes de nœuds capteurs. Ceci ouvre la porte à des techniques avancées de communication de type MIMO. Dans un premier temps, les différents aspects caractérisant les réseaux de capteurs sans fil sont introduits. Puis, les efforts engagés pour optimiser la conservation de l'énergie dans ces réseaux sont résumés. Les concepts de base de systèmes MIMOs sont abordés dans le deuxième chapitre et l'exploration par voie numérique de différentes pistes de la technologie MIMO sont exposées. Nous nous intéressons à des techniques de diversité de polarisation dans le cadre de milieux de communication riches en diffuseurs. Par la suite, des méthodes de type beamforming sont proposées pour la localisation dans les réseaux de capteurs sans fil. Le nouvel algorithme de localisation est présenté et les performances sont évaluées. Nous identifions la configuration pour la communication inter-grappes qui permet pour les meilleurs compromis entre énergie et efficacité spectrale dans les réseaux de capteurs sans fil. Finalement, nous envisageons la technique de sélection de nœuds capteurs afin de réduire la consommation de l'énergie dans le réseau de capteur sans fil
The aim of this work is to study from a signal processing point of view the use of MIMO (Multiple Input Multiple Output) communication systems for algorithms dedicated to wireless sensor networks. We investigate energy-constrained wireless sensor networks and we focus on cluster topology of the network. This topology permits for the use of MIMO communication system model. First, we review different aspects that characterize the wireless sensor network. Then, we introduce the existing strategies for energy conservation in the network. The basic concepts of MIMO systems are presented in the second chapter and numerical results are provided for evaluating the performances of MIMO techniques. Of particular interest, polarization diversity over rich scattering environment is studied. Thereafter, beamforming approach is proposed for the development of an original localization algorithm in wireless sensor network. The novel algorithm is described and performances are evaluated by simulation. We determine the optimal system configuration between a pair of clusters that permits for the highest capacity to energy ratio in the fourth chapter. The final chapter is devoted to sensor nodes selection in wireless sensor network. The aim of using such technique is to make energy conservation in the network

“" at environment and those structures invest the vast di# erences of nature with meaning intelligible to, indeed imagined by, a mankind and they involve in the end all those complex relationships of human buildings with each other that shape within nature a man-made topography.” (Scully 1991: 1) Humankind has forever been placed outside the realm of nature, peering in as a spectator through a frame. ! at which is organic is ‘natural’ and that which we create is ‘man- made’. A beaver’s nest would not exist if the beaver had not built it, yet it is ‘natural’. If humans are of earth then surely that which we build is ‘natural’ as well? Let us translate the ‘man-made’ back into the natural world. Lake Malawi makes up one-third of its country. Local Malawians are dependent on this resource for livelihood, food, water and sanitation but over" shing threatens it. Cichlid " sh native to the lake are a rapidly evolving species, they are also a rapidly depleting food source. ! e lake with its local " shing villages is nature with us in it. I propose an underwater observatory on the shoreline of the lake, to address a species and a food source. Local Malawians inhabit the shoreline within a nature that has been adapted to meet the needs of human activity. Fishermen prepare their nets at sunset, go out at night with # ickering para$ n lamps, and return at sunrise with a diminishing catch of Chambo while women make their way to the water’s edge to wash and collect water. ! e chosen site is situated in Cape Maclear at the entrance to Lake Malawi National Park which is protected aquatic sanctuary. An established tourist industry supports the local community of Chembe village. ! e observatory is a threshold to the park and a liminal boundary between land and water, in and out, above and below. ! e programme is categorized within Science and Community. Communal facilities address alternative food sources, sanitation and education while science facilities document and record the rapid evolution of Cichlids. If architecture can be viewed as a hybrid, a construct of both human culture and nature, then let an amphibious structure rest upon the water’s edge, partially submerged and partially elevated over water and land. Acting as a bathometer, climatic changes mark its surface as it modi" es nature while nature modi" es it. Designed to adapt to # uctuating water levels, the facility evolves as rapidly as its native Cichlid " sh. By reframing the mindset of locals and visitors, we become part of an evolving ecosystem and may begin to truly acknowledge the part we play in it. We attempt to preserve a species and a livelihood, yet preservation may be viewed as the pursuit of stagnation. Our livelihoods, our food and our buildings are of this earth. Like nature, they must continuously adapt, modify and evolve.

The main purpose of this research was to investigate the impact of open pit mining on the Land Use Land Cover Change (LULCC) of the Yatela region in Mali. The methodology used to assess the open pit mining operations were remote sensing vegetation indices (NDVI) and LULC maps at a four year interval from 1999 to 2015. The Support Vector Machine (SVM) classification was used to create the LULC maps. Assessment of the quality from SVM classification outputs were analyzed using the confusion matrix technique. Three satellites (Landsat 5, 7 and 8) were used to analyze the images that were extracted from scene path 202 row 050. The NDVI results were able to detect the development and expenditure of the open pit mine in the Yatela region from 1999 to 2015. The roads and open pit mine area were easily detected from the 1999 NDVI results. Over the years the vegetation cover varied in the Yatela region, good vegetation cover was present before mine operations (1999) and after the mine closure (2015). The average overall accuracy for the five classified images was 84.31%. The change detection statistics showed that there were significant changes in each of the five classes over the 16 year period. Anthropogenic factors are assumed to be the major contributing factor to the Land Use Land Cover Change in the Yatela region. Nonetheless, this should not mean that climate factors can be neglected as contributing factors to LULCC in the region. Due to data limitation this research was unable to test any climatic influences.

This thesis reports on the findings of a three year study on the economIc aspects of the woodcarving industry in Kenya. Woodcarving provides one of the most important uses of wood in Kenya both in terms of economic returns (export value estimated at US$ 20 million annually) and generation of self-employment opportunities (60,000 carvers and estimated 350,000 dependants). The industry is facing an imminent collapse owing to the depletion of prime carving tree species which has supported it since 1919. The key objectives of the study were; (a) To quantify the diversity of species in trade (volumes) and their pricing trends both for the raw materials and products (carvings); (b) determination of profit margins that accrue from carving activities and prices of these species for alternative uses; (c) to look into the possibility of onfarm production of fast growing species (Azadirachta indica) for carving, as well as Brachylaena huillensis . Each of these was pursued mainly through field surveys at seven main areas where carving is carried out in Kenya. The annual carving volume consumed in Kenya is in excess of 15,000 cubic metres concentrated on about ten tree species. However about 57% of this volume is contributed by Brachylaena huillensis. Diameter profiles of logs of the carving wood is dominated by 10-16 cm diameter timber which is an indication of resource scarcity where juvenile trees are increasingly being targeted. The prices of carving wood are distorted and are far helow the market prices largely due to the prevalence of illegal sourcing from state forests. The study has estimated that the stumpage level for Brachylaena huillensis should be raised from Ksh 4 053 to Ksh 12 000 per m3 if control on the current level of depletion is to be ensured. For the other species, the current stumpage levels need to be raised three fold. The weaknesses of the existing policies and legislation governing the access to carving wood have been examined and appropriate recommendations have been given. However, as a long term measure to benefit the carvers and conservation of the last remaining East African forests, changing buyer and carving wood sourcing behaviour from unsustainable felling of slow growing hardwoods to sustainable on-farm production is discussed. The study demonstrates that Azadirachta indica can attain a carvable size with a dbh of 16 cm in 17 years. The study has also established that potential profits (revenue) which can accrue from carvings made per unit wood volume (one cubic metre of wood or equivalent to about 20 logs of I.Sm long, 20cm diameter) can be as high as Ksh 270,000 within a period of four months. This is about four times the unit value of sawn timber of some of the finest hardwoods in the Kenyan market. The study therefore calls for restrictions on the utilization of these prime carving species on uses other than carving.

This study’s primary objective was to create a framework for developing authenticity, by exploring women’s experiences of authenticity and how these relate to their wellbeing in a male-dominated work environment. Twelve purposively chosen women participated in the study, comprising six police officers and six traffic officers from the Western Cape province in South Africa. Data were gathered through narrative interviews by using open-ended questions, and analysed by applying thematic analysis. The research findings revealed that challenges or stressors in their law enforcement environment serve as potential agents for moving the self away from best-self in the authenticity dynamic, resulting in the need for coping and therefore for developing authenticity. The framework for developing authenticity was constructed as an ongoing and unfolding process comprising the following: experiencing challenges or stressors; turning within; recognising possible ways of being; managing perceptions, thoughts, emotions and behaviour; making conscious choices and taking responsible actions; as well as evaluating responses and consequences against best-self standards. During this process various best-self characteristics and associated skills are developed and employed, but also serve as best-self standards against which to evaluate growth and transformation. Secondary objectives aimed to advance the concept of authenticity in the study of well-being as a discipline of psychology. It also aimed to make a methodological contribution by applying hermeneutic phenomenological and transpersonal approaches in a novel way.

Die primêre doel van hierdie studie was om 'n raamwerk vir die ontwikkeling van egtheid te skep, deur vroue se ervarings van egtheid te ondersoek en hoe dit verband hou met hul welstand in 'n manlik-gedomineerde werksomgewing. Twaalf doelgerig gekose vrouens het deelgeneem aan die studie, wie bestaan het uit ses polisiebeamptes en ses verkeersbeamptes uit die Wes-Kaapse provinsie in Suid- Afrika. Data was versamel deur middel van narratiewe onderhoude deur oop vrae te gebruik, en ontleed deur tematiese analise toe te pas. Die navorsingsbevindings het aan die lig gebring dat uitdagings of stressors in hul wetstoepassingsomgewing as potensiële agente dien om die self weg te beweeg van die beste-self in die egtheid dinamika, wat die behoefte aan coping tot gevolg het en dus vir die ontwikkeling van egtheid. Die raamwerk vir die ontwikkeling van egtheid is saamgestel as 'n deurlopende en ontvouende proses wat die volgende insluit: ervaring van uitdagings of stressors; keer na binne; erkenning van moontlike maniere om te wees; hantering van persepsies, gedagtes, emosies en gedrag; maak bewustelike keuses en neem verantwoordelike aksies; sowel as die evaluering van reaksies en gevolge teen die beste-self standaarde. Gedurende hierdie proses word verskeie beste-self eienskappe en verwante vaardighede ontwikkel en aangewend, maar dien ook as die beste-self standaarde om groei en transformasie te evalueer. Sekondêre doelwitte het ten doel om die konsep van egtheid in die studie van welstand as dissipline van sielkunde te bevorder. Dit is ook daarop gemik om 'n metodologiese bydrae te lewer deur hermeneutiese fenomenologiese en transpersoonlike benaderings op 'n nuwe manier toe te pas.

Previous research has found that the clarity of information provided to raters about women managers’ performance affects ratings of their competence, likeability, and overall evaluation. The current study sought to contribute to this literature by examining whether individual differences of raters can explain the reason for differential performance evaluations of male and female managers, despite them both performing equally. For this purpose, the current research extended the findings of Heilman and colleagues by replicating their methodology while introducing a moderator variable, the rater’s Implicit Person Theory (IPT). The IPT differentiates people into either entity theorists (that is, those who believe that behavior is trait-based and therefore fixed and stable) and incremental theorists (those who believe that behavior is situationally mediated and hence, changeable). Specifically, it was proposed that the effects found in the previous study would be stronger when the rater possessed an entity theory as opposed to an incremental theory. In doing so, this research attempted to provide an understanding of why male and female managers might be given different ratings, all other things being equal. Analyses revealed results that were consistent with, as well as some that were quite inconsistent with, previous findings. Rater IPT was found to have a significant effect on ratings provided by male participants but not those of female participants. Other findings and implications are discussed and limitations and future research directions are stated.

The paucity of women in senior leadership positions as indicated in the Business Women Association of South Africa 2011 census corroborates that gender equality is still a concerning issue even in the democratic era that we live in. This study explores career developmental experiences of women in senior leadership position in the civil engineering industry. The primary objective was to investigate how these professional women were managing their careers and what career experiences contributed to their ascent to the senior echelons of management. Meaning to the career experiences of these women had been given according to the self-determination theory. By means of purposive selection, seven women at senior management level were selected from both the private and public sectors in the civil engineering industry. Based on the semi-structured interviews conducted, personal documents reviewed and footnotes recorded; it was evident that there were different factors that had facilitated the ascent of these women to senior positions. Their career experiences were also characterised by challenges that subsequently instigated the development of coping strategies and methods. The study has implications for organisations in civil engineering that wish to attract and retain women from generations to come.

Nursing is a female dominated profession; making it difficult for men in the profession to excel in their caring capacities as nurses. This study aimed at identifying and describing male and female nurses' insights into and perceptions of socio-cultural influences on the recruitment and retention of men in the nursing profession and also explores their experiences in providing intimate care to patients of opposite gender. The study adopted a qualitative research methodology: 16 male and 11 female nursing students were purposively sampled and were interviewed using semi-structured questions. Themes of nursing seen as women's work; low status; stigma; caring and helping others were developed. Feelings of embarrassment and discomfort; fear and refusal of care were experienced when providing intimate care to patients of opposite gender; this has led male participants to develop strategies to protect themselves from sexual accusations. The Nursing Education Institutions (NEIs) have insufficient toilets for male nursing students; there is a lack of male role models and feminine pronouns are used when relating to professional nurses. Evidently socio-cultural perceptions of nursing enforce a negative image. The difficulties experienced by male and female nurses when providing intimate care and lack of male-friendliness in NEIs were discussed. These factors will lead to a further decline in the recruitment and retention of men in nursing; skilled and intelligent nurses are leaving the profession.
