Decision support systems (DSS) that integrate long-term duck population and land use data are currently being used to develop conservation programs on the Canadian prairies. However, understanding inter-relationships between ducks and other grassland bird species would greatly enhance program planning and delivery among various bird conservation initiatives. Therefore, to achieve these goals, grassland bird species richness and relative abundance were compared between areas of low, moderate and high predicted waterfowl breeding densities (strata) in the southern Missouri Coteau, Saskatchewan. Roadside point counts were conducted during spring 2001 and 2002, and habitats were delineated within 400 m radius of each point. More birds of more species were encountered in the high density waterfowl stratum when compared with low but species that tended to co-occur with ducks were primarily wetland-associated. Overall, duck and other grassland bird species richness and abundance were moderately correlated (0.69 > r > 0.37, all Ps < 0.05); strong positive correlations between priority species of conservation concern and northern pintails were not found. No difference in mean number of priority grassland species occurred among strata, but differences were found for both number of species and total birds detected among routes within strata. High duck density stratum was more heterogeneous, consisting of greater areas of forage, shrub, wetlands, and open water bodies whereas low stratum contained larger, more uniformly-shaped habitat patches and greater proportion of cropland. Ordination analyses revealed that most priority species occurred in grassland-dominated sites with lower shrub area and wetland density whereas most wetland-associated species, including ducks and 2 priority species (Wilsons phalarope and marbled godwit) inhabited cultivated areas with higher wetland density. Ducks and priority species generally did not co-occur at the stop-level in highly heterogeneous landscapes but suitable habitats for both groups may exist in near proximity. In homogeneous landscapes, ducks and other wetland-associated common species were less abundant because of limited number of suitable wetlands. To achieve these dual goals, conservation efforts should be focused in areas containing wetlands adjacent to contiguous tracts of native pasture.

This thesis is a case study of coordination policies and practices in child protection services. The study is an exploratory, descriptive account of the processes and outputs of interagency coordination rather than a hypothesis-testing study or an evaluation of the outcomes of coordination. It is based on empirical research undertaken in two research sites in the north of England. The principal data sources used in the research were: an analysis of the social services departmental case records relating to a sample of 48 children on child protection registers for physical or sexual abuse; interviews with 90 professionals (social workers, teachers, community nurses, police officers, doctors and others), drawn from a sub-sample of the 48 cases; a questionnaire issued to those interviewed and selected others, completed by 81 respondents; and analysis of central government guidance, local interagency procedures and other documents. In Chapter One of the thesis, selected topics in the literature on interagency coordination and the policy background to the study are reviewed. The research methods used and the characteristics of the case sample and the interview and questionnaire respondents are presented in Chapter Two. The principal research findings are presented in Chapters Three to Eleven covering three main topics: i) interagency coordination in the key phases of a case career (namely referral, initial investigation, medical assessment, case conferences, child protection plans and intervention, monitoring and review) ii) an examination of local interagency procedures and the role of Area Child Protection Committees and iii) the perceptions and experiences of respondents concerning interagency work. The thesis concludes that there is a high degree of routinised coordination with a relatively clear division of labour in child protection services; that coordination involves principally the exchange of information, arranging for the sequential and separate performance of key tasks and some limited shared decision-making but that there is little joint hands-on collaboration; that interagency activity peaks in the early phases of the construction of a case and diminishes thereafter; that the implementation of policy guidance may be seen as relatively successful and that there is some support for the idea that interagency coordination strategies tend towards conservatism.

The current study aimed to discover whether, and to what extent, children and adolescents at risk of Developmental Coordination Disorder (DCD) perceive themselves as lacking competence, control, social support and self-worth. In addition, the study aimed to discover whether, and to what extent, children and adolescents at risk of DCD experience more trait and state anxiety than their peers. Fifty-eight children aged 8- to 10-years identified as being at risk of DCD were matched with 58 control children on age and gender, and fifty-one adolescents aged 12- to 14-years at risk of DCD group were matched with 51 control adolescents. Children and adolescent at risk of DCD were compared to the control group on measures of perceived competence, perceived control, perceived social support, self-worth and anxiety. Multivariate Analysis of Variance revealed that children and adolescents at risk of DCD performed significantly more poorly than the control group on measures of perceived competence, perceived control, perceived social support, self-worth and state and trait anxiety. In addition, significant differences were found on some measures for age, whilst only the self-perception profile differentiated gender.Based on the assumption that children and adolescents with poor motor coordination do have negative views of self and experience relatively high levels of anxiety, a second aim of the study was to test an aetiological model of anxiety. Harters (1987) model of the determinants of self-worth provided a sound theoretical basis for investigating the relationships between self-perceptions and affect. Self-perception, according to Harter, precedes emotional and behavioural outcomes. A series of path analyses conducted separately for each group revealed differences in the pattern of interrelationships between the dependent variables for children and adolescents at risk of DCD ++ / and the control group. The salient findings were that for both groups physical appearance was an important and consistent determinant of self-worth. Few significant pathways were identified for those in the DCD group limiting the conclusions that could be drawn from this study.Overall, given the negative consequences of poor motor coordination identified in the current study it would seem imperative that early assessment and diagnosis of DCD be introduced into the school system.

The chemistry and physical properties of actinide complexes has become increasingly significant and relevant since the dawn of the nuclear age. In addition to increasing the potency of nuclear power and the safety and disposal of its subsequent waste products, exploration of the chemistry of actinide complexes provides a fascinating insight into the increased complexity and divergence of reactivity of these complexes when compared to transition metal complexes. Chapter One provides a brief introduction to the chemistry of actinides and in particular, the major focus of this work, of thorium. This is followed by a survey of examples of rare examples of thorium complexes with a formal oxidation state other than Th (IV). Following this is a review of selected examples of thorium (IV) complexes exhibiting unusual reactivity surveying thorium hydride and alkyl complexes initially. This progresses into reviewing the chemistry of thorium complexes containing multiple bonds to non-metal atoms, beginning with carbon atoms and then progressing to atoms in the chalcogen and pnictogen groups. The introduction finishes with an investigation into the properties of the terphenolate ligands used in this study, including examples of unusual complexes that they have been shown to stabilise. In Chapter Two, an exploration into the catalytic activity of fairly simple actinide amide catalysts, N”2Th (IV) {k2-N(SiMe3)SiMe2CH2, N”2U (IV) {k2-N(SiMe3)SiMe2CH2} and UN”3, upon terminal acetylenes is presented. The chapter begins with a brief introduction summarising the previous reactivity observed in the catalysis of terminal acetylenes, with particular focus on actinide-based catalyst mediated reactions. The catalytic results on a variety of terminal acetylenes with different steric and electronic properties is then reported upon. It is found that high conversions and selectivities can be achieved upon optimisation of the catalytic process. It was also found that the different catalysts and substrates favoured different products, with selective oligomerisation and cyclotrimerisation reactions observed. The differing reactivities lend support to the role of f-electrons upon the catalytic route of the reaction. Conclusions are discussed at the end of the chapter. In Chapter Three, the synthesis and characterisation of heteroleptic terphenolate thorium chloride complexes and their subsequent reactivity was investigated. The synthesis and characterisation of ThCl2(OTerMes)2DME and ThCl2(OTerMes)2(H2O)3 are initially described. The reactivity of these complexes favoured transmetallation of the terphenolate ligands, with the complexes; [Li(OTerMes)THF]2, [Li(OTerMes)]2THF, μ3- (TerMesO)μ3-(CH2SiMe3)3Li4, LiAlH2(OTerMes)2, [(THF)K(OTerMes)]2, MgCl(OTerMes)(THF)2, MgBr(OTerMes)(THF)2 and Fe(OTerMes)2(py)2 synthesised and characterised from reactions attempting to transform the ancillary chlorido-ligands. The reactivity of ThCl2(OTerMes)2DME was found to not be solely transmetallation of the terphenolate ligands as elucidated by the synthesis and characterisation of [Th(OTerMes)2(Cl)2(4,4’- bipyridyl)1.5]∞ and [MgTh2μ2-Cl2μ3-Cl(OTerMes)2(C4H7)2μ-η3:η3(C4H7)H]. The synthesis of [MgTh2μ2-Cl2μ3-Cl(OTerMes)2(C4H7)2μ-η3:η3(C4H7)H] was found to proceed via a reductive elimination route with concomitant formation of a terphenolate transmetallation product Mg(OTerMes)2(THF)2. The formation of[Th(OTerMes)2(Cl)2(4,4’- bipyridyl)1.5]∞ was achieved via reaction with the Lewis base 4-4’ bipyridine. Reactions attempting to form heteroleptic uranium terphenolate complexes were also detailed. Conclusions are discussed at the end of the chapter. In Chapter Four, the synthesis and characterisation of heteroleptic terphenolate thorium borohydride complexes and their subsequent reactivity was investigated. It was found that the conversion of ThCl2(OTerMes)2DME to Th(BH4)2(OTerMes)2DME proceeded smoothly using a precedented reaction route. In contrast to ThCl2(OTerMes)2DME, reaction with a Lewis acid was found to result in abstraction of the solvating DME molecule, resulting in the synthesis and characterisation of Th(BH4)2(OTerMes)2. In similarity to ThCl2(OTerMes)2DME, Th(BH4)2(OTerMes)2DME was found to react with a Lewis base (4-4’ bipyridine) to form Th(BH4)2(OTerMes)2(4,4’ bipyridine)∞. However, despite the increased robustness and versatility of the borohydride complexes, transmetallation of the terphenolate complexes remained an issue as shown by the synthesis and characterisation of Mg(OTerMes)((μ-H)3BH)THF)2. Th(BH4)2(OTerMes)2 was found to be able to facilitate small molecule activation in a variety of substrates, encompassing CO, CO2 and CS2 amongst others. In most cases this small molecule activation favoured the formation of BMe3, with the concomitant formation of HB(OTerMes)2 in the case of CO2 and CS2. Attempts at catalysis of isonitriles and terminal acetylenes by Th(BH4)2(OTerMes)2 are presented with mixed results. Conclusions are discussed at the end of the chapter. In Chapter Five, investigations into the effects of changing the donor atom of the terphenyl moiety were probed. The chapter began by examining the differing properties of a phosphorous atom acting as a ligating atom, as opposed to the oxygen atom seen in Chapters Three and Four. The chapter continued by detailing the result of reactions attempting to synthesise and characterise terphenyl phosphino-actinide complexes. It was found that in the case of actinides with easily accessible lower oxidation states, i.e. U (IV), that reductive elimination was favoured, culminating in the isolation of (TerMesPH)2. Following this result attempts were made to modify the ligand system in an attempt to divert the reaction away from this product, in the hope of isolating a phosphino-actinide complex. Reactions attempting to ligate the terphenyl moiety via the aryl α-carbon to thorium were also detailed, resulting in radicular degeneration and the isolation of nBuTerTrip and ClTerTrip. Conclusions are discussed at the end of the chapter. Experimental and characterising data are provided in Chapter Six.
