Veerapen, Parmaseeven Pillay. "Recurrence relationships and model monitoring for Dynamic Linear Models." Thesis, University of Warwick, 1991. http://wrap.warwick.ac.uk/109386/.
Full textAbstract:
This thesis considers the incorporation and deletion of information in Dynamic Linear Models together with the detection of model changes and unusual values. General results are derived for the Normal Dynamic Linear Model which naturally also relate to second order modelling such as occurs with the Kalman Filter, linear least squares and linear Bayes estimation. The incorporation of new information, the assessment of its influence and the deletion of old or suspect information are important features of all sequential models. Many dynamic sequential models exhibit conditioned, independence properties. Important results concerning conditional independence in normal models are established which provide the framework and the tools necessary to develop neat procedures and to obtain appropriate recurrence relationships for data incorporation and deletion. These are demonstrated in the context of dynamic linear models, with particularly simple procedures for discount regression models. Appropriate model and forecast monitoring mechanisms are required to detect model changes and unusual values. Cumulative Sum (Cusum) techniques widely used in quality control and in model and forecast monitoring have been the source of inspiration in this context. Bearing in mind that a single sided Cusum may be regarded essentially as a sequence of sequential tests, such a Cusum is, in many cases, equivalent to a Sequence of Sequential Probability Ratio Tests in many cases, as for example in the case of the Exponential Family. A relationship between Cusums and Bayesian decision is established for a useful class of linear loss functions. It is found to apply to the Normal and other important practical cases. For V- mask Cusum graphs, a particularly interesting result which emerges is the interpretation of the distance of the V vertex from the latest plotted point as the prior precision in terms of a number of equivalent observations.

Full textAbstract:
This study evaluated the school psychologist's perception of effective models of consultation based upon referral problem and parent, teacher, and student response to treatment. Analyses of covariance determined that (a) parents' receptivity and total number of teacher contacts significantly influenced the parents' response to treatment; (b) teacher receptivity and total number of parent contacts significantly affected teachers' response to treatment; (c) students' response to treatment was significantly affected by the model of teacher consultation and the average number of minutes spent with the school psychologists; and (d) students in a Mental Health consultation group responded significantly more favorably than s tudents in Behavioral or Collaborative consultation groups.

Cheng, Yan. "Wood property relationships and survival models in reliability." Thesis, University of British Columbia, 2010. http://hdl.handle.net/2429/27953.
Full textAbstract:
It has been a topic of great interest in wood engineering to
understand the relationships between the different strength
properties of lumber and the relationships between the strength
properties and covariates such as visual grading characteristics. In
our mechanical wood strength tests, each piece fails (breaks) after
surviving a continuously increasing load to a level. The response of
the test is the wood strength property --
load-to-failure, which is in a very
different context from the standard
time-to-failure data in Biostatistics. This
topic is also called reliability analysis in
engineering.
In order to describe the relationships among strength properties, we
develop joint and conditional survival functions by both a
parametric method and a
nonparametric approach. However,
each piece of lumber can only be tested to destruction with one
method, which makes modeling these joint strengths distributions
challenging. In the past, this kind of problem has been solved by
subjectively matching pieces of lumber, but the quality of this
approach is then an issue.
We apply the methodologies in survival analysis to the wood strength
data collected in the FPInnovations (FPI) laboratory. The objective
of the analysis is to build a predictive model that relates the
strength properties to the recorded characteristics (i.e. a survival
model in reliability). Our conclusion is that a type of wood defect
(knot), a lumber grade status (off-grade: Yes/No) and a lumber's
module of elasticity (moe) have statistically significant effects on
wood strength. These significant covariates can be used to match
pieces of lumber. This paper also supports use of the accelerated
failure time (AFT) model as an alternative to the Cox
proportional hazard (Cox PH) model in the analysis of
survival data. Moreover, we conclude that the Weibull AFT model
provides a much better fit than the Cox PH model in our data set
with a satisfying predictive accuracy.

Full textAbstract:
This study first investigated the association between individuals' chronic regulatory styles and their attachment models in adult close relationships, and then looked at how individuals' chronic regulatory styles interact with their attachment models to influence relationship maintenance strategies (RMS) such as accommodating one's partner's transgressions and making personal sacrifices for the relationship. One hundred twenty-one dating-students completed the computerized Selves Questionnaire (Higgins et al., 1997) assessing ideal and ought discrepancies and their chronic accessibility (promotion and prevention focus strength), and then answered questions addressing attachment, accommodation and willingness to sacrifice. Results revealed that ought discrepancies were associated with avoidant attachment for high prevention focus strength individuals, whereas ideal discrepancies were associated with anxious attachment for low promotion focus strength individuals. Furthermore, prevention focus strength interacted with avoidant attachment, such that individuals with a strong prevention focus engaged in RMS to the extent that they were not avoidantly attached.

Full textAbstract:
Retrieval models are the core components of information retrieval systems, which guide the document and query representations, as well as the document ranking schemes. TF-IDF, binary independence retrieval (BIR) model and language modelling (LM) are three of the most influential contemporary models due to their stability and performance. The BIR model and LM have probabilistic theory as their basis, whereas TF-IDF is viewed as a heuristic model, whose theoretical justification always fascinates researchers. This thesis firstly investigates the parallel derivation of BIR model, LM and Poisson model, wrt event spaces, relevance assumptions and ranking rationales. It establishes a bridge between the BIR model and LM, and derives TF-IDF from the probabilistic framework. Then, the thesis presents the probabilistic logical modelling of the retrieval models. Various ways of how to estimate and aggregate probability, and alternative implementation to nonprobabilistic operator are demonstrated. Typical models have been implemented. The next contribution concerns the usage of of context-specific frequencies, i.e., the frequencies counted based on assorted element types or within different text scopes. The hypothesis is that they can help to rank the elements in structured document retrieval. The thesis applies context-specific frequencies on term weighting schemes in these models, and the outcome is a generalised retrieval model with regard to both element and document ranking. The retrieval models behave differently on the same query set: for some queries, one model performs better, for other queries, another model is superior. Therefore, one idea to improve the overall performance of a retrieval system is to choose for each query the model that is likely to perform the best. This thesis proposes and empirically explores the model selection method according to the correlation of query feature and query performance, which contributes to the methodology of dynamically choosing a model. In summary, this thesis contributes a study of probabilistic models and their relationships, the probabilistic logical modelling of retrieval models, the usage and effect of context-specific frequencies in models, and the selection of retrieval models.

Full textAbstract:
Context. Software systems, becoming larger and more complex day-by-day, have resulted in software development processes to become more complex to understand and manage. Many companies have started to adapt distributed software engineering practices that would allow them to work in distributed teams at different organizations and/or geographical locations. For example, model-driven engineering methods are being used in such global software engineering projects. Among the activities in model-based software development, consistency checking is one of the widely known ones. Consistency checking is concerned with consistent models; in particular, having a consistent group of multiple models for a whole system, e.g., multiple models produced by distributed teams. Objectives. This thesis aims to find out how ‘Global Consistency Checking (GCC)’ can be utilized for exploring inconsistency problems between distributed models; particularly among UML class diagram relationships (in terms of consistency), as well as how GCC can be scaled with large number of models and relationships. Thereby, these inconsistencies are also aimed to incrementally resolve in our approach. Methods. We made a review in distributed software development domain and model management, in particular, methods of consistency checking between ‘Distributed Models (DM)’. Next, we conducted two case studies in two problem domains in order to apply our ‘consistency checking methodology’. We concurrently constructed and implemented new consistency rules, most of which are gathered from literatures and brainstorming with our coordinators. Generally, the method contains implementing different models of the case studies with a tool support and trying to figure out overlaps, merging models and checking the merged model against the consistency rules, and evaluating the results of GCC. We mainly addressed issues focused on consistency checking of individual models and the mapping between them e.g., pair-wise consistency checking (PCC), which are incapable of fully addressing problems against any consistency rules encountered in distributed environments. Results. We have identified seven types of inconsistency, which are divided in two groups named ‘Global inconsistency’ and ‘Pair-wise inconsistency’. In the first case study, we have 94 global inconsistencies and 73 pair-wise. In the second one, 14 global and 25 pair-wise inconsistencies are resulted. During ‘Resolution approach’, we followed six steps as a ‘systematic procedure’ for resolving these inconsistencies and constructed new merged model in each iteration. The initial merged model (inconsistent model) as an input for the first step has 1267 elements, and the consistent merged model (the output) from the sixth step has 686 elements. ‘time duration’ and ‘required effort’ for checking consistency against each ‘consistency rule’ were recorded, analyzed and illustrated in Sections 4.1.5 and 4.2.4. Conclusions. We concluded that GCC enables us to explore the inconsistencies, inclusive of resolving them and therefore, refining the relationships between different models, which are difficult to detect by e.g., a pair-wise method. The most important issues are: The number of model comparisons conducted by PCC, The inability of PCC for identifying some inconsistencies, Model relationships refinement and classification based on PCC approach will not lead to a final consistent DM, whereas, GCC guarantees it. Consistency rules application, inconsistency identification and resolving them could be generalized to any UML class diagram model representing a problem domain within the fields of consistency checking in software engineering.0046760850792, 0046737749752

Full textAbstract:
This thesis is concentrated broadly in the field of mathematical industrial economics and more specifically upon what is known in the literature as principal-agent relationships. It focuses on investigating the nature of optimal contracts between, say, owners of the firm and the manager appointed by them to run the affairs of the firm or yet again between the owners and the workers employed in the firm. Chapter 1 introduces by first establishing the background of the analysis and then summarising the results of the thesis. The background consists mainly of implicit contract models, both of the symmetric and asymmetric information kind, and models of moral-hazard. The results of the thesis are contained in four chapters following the introduction. Chapters 2 and 3 are concerned primarily with the use made of principal agent models in the asymmetric-information implicit contract literature. This literature attempts to explain involuntary unemployment by showing that the inefficiency generated by the asymmetry in information between the principal (firm) and the workers (agent) manifests itself in employment lower than the efficient level. We show instead that results are altered in quite striking ways depending not only on the eventual asymmetry of information but also the asymmetry prevailing, say, when the agent takes his action, but before production occurs. Chapter 4 makes the case in favour of using the first-order approach in solving principal-agent models by proposing a weakening of the sufficient conditions which make this approach valid. Such weakening extends the range of cases - given by particular configurations of utility and density functions - for which the analytical convenience of the first-order approach may be utilised. Chapter 5 uses moral-hazard models and the first-order approach to answer the specific question "Should owner-managed firms with limited liability be taxed a higher rate than similar firms with unlimited liability?". The answer is "Yes, but only under certain conditions". Chapter 6 summarises and draws together the various strands of the arguments presented in the thesis.

Full textAbstract:
This thesis is focused upon chemistry as a school subject and students' interpretations and use of formally introduced teaching models. To explore students' developing repertoire of chemical models, a longitudinal interview study was undertaken spanning the first year of upper secondary school chemistry. Matter in its different states was selected as the target framework for this study. The results presented are derived from both generalisations of groups of students as well as a case study describing an individual learner's interpretation of formal content. The results obtained demonstrated that the formal teaching models provided to the students included in this study were not sufficient to afford them a coherent framework of matter in its different states or for chemical bonding. Instead, students' expressed models of matter and phase change were to a high degree dependent on electron movement (Paper I), anthropomorphism (Paper II) and, for one student, a mechanistic approach based on small particles and gravitation (Paper III). The results from this study place focus on the importance of learners' prior learning (previous experiences) and the need to develop a coherent framework of formal teaching models for the nature of matter and phase change.

Full textAbstract:
The present research included gender in Person-by-Situation interaction models in the study of interpersonal behavior and affect. An event-contingent recording methodology was used to measure behavior and affect across situations and over time in natural settings for a 20-day period with adult community samples. Three dyadic situations of personal relationships that varied in gender composition and emotional closeness were examined: same-sex friendships, opposite-sex friendships, and romantic relationships.Traditional investigations of gender, disregarding situational factors, have determined that women are generally less agentic, more communal, and more emotional than men. The present research demonstrated that the interpersonal behavior of agency and communion were influenced by both situation and gender. In same-sex friendships, women and men behaved consistently with their gender-stereotypes: pairs of women were more communal than pairs of men and pairs of men were more agentic than pairs of women. In mixed-sex dyads, individuals did not behave consistently with gender-stereotypes. Women and men behaved similarly on agency and communion with opposite-sex friends. In interactions with a romantic partner, women behaved less communally than men. Personal relationship situations were found to moderate agentic and communal behaviors, demonstrating the plasticity and variability of gender role behaviors.
Pleasant and unpleasant affect intensity was influenced by situation but not gender. The present research demonstrated that women and men reported experiencing similar levels of affect across the relationship situations. As predicted, individuals experienced both greater pleasant and unpleasant affect in romantic relationships than friendships.
The current research confirmed that there is a need to move beyond the conception that the stereotypic characteristics of men and women reside within individuals. Gender should be included in Person-by-Situation interaction models, taking into consideration psychological and social factors that shape the expression of sex-differentiated behaviors and the experience of emotions.

Full textAbstract:
This purpose of this study was fivefold: a)to examine the relationship between participants' reported number of positive lesbian and/or gay relationship role models their relationship outcomes (i.e., satisfaction, success, degree of closeness, and length of relationship); b) to explore the relationship between participants' level of internalized negative views of lesbian relationships and their own relationship outcomes; c) to investigate the relationship between participants' number of positive relationship role models and their level of internalized negative views of lesbian relationships; d) to examine whether participants who reported acceptance of negative stereotypes of lesbian relationships and had fewer role models also reported lower levels of interpersonal selfefficacy; e) and to investigate the relationship between participants' level of interpersonal self-efficacy and their relationship outcome (satisfaction, success, degree of closeness, and length of relationship). The study included 192 lesbian women (age 18-71 years; M = 30.6) who responded to five questionnaires: the Relationship Information Questionnaire, the Role Models Questionnaire, the Interpersonal Self-Efficacy Scale, the Internalized Negative Views of Lesbian Relationships Questionnaire, and a demographic information page. Results showed that there was no significant correlation between participants' reported number of role models and their relationship outcome (Hypothesis One). Similarly, the current study failed to find a relationship between participants' level of internalized of negative views of lesbian relationships and their own relationship outcomes (Hypothesis Two). In addition, there were no significant correlations between participants' number of positive relationship role models and their level internalized of negative views of lesbian relationships (Hypothesis Three). Furthermore, the correlation between role models and self-efficacy was not significant; however, there was a significant correlation between participants' self-efficacy and their level of internalized negative views of lesbian relationships (Hypothesis Four). The results indicated that participants' level of interpersonal self-efficacy is positively correlated with their relationship satisfaction, success, and degree of closeness. However, self-efficacy was unrelated to relationship length (Hypothesis Five). Possible explanations, limitations, and suggestions for future research are discussed.Department of Psychological Science

Full textAbstract:
Sarizotan 1-[(2R)-3,4-dihydro-2H-chromen-2-yl]-N-[[5-(4-fluorophenyl) pyridin-3-yl]methyl] methenamine, showed an in vivo pharmaco-EEG profile resembling that of methylphenidate which is used in attention deficit/hyperactivity disorder (ADHD). In turn, we tested sarizotan against impulsivity in juvenile rats measuring the choice for large delayed vs. a small immediate reward in a T-maze and obtained encouraging results starting at 0.03 mg/kg (plasma levels of ~11 nM). Results from rats treated neonatally with 6-hydroxydopamine (6-OHDA), also supported anti-ADHD activity although starting at 0.3 mg/kg. However, microdialysis studies revealed that free brain concentration of sarizotan at active doses were below its affinity for 5-HT1A receptors, the assumed primary target. In contrast, electrophysiological experiments in mid-brain Raphé serotonergic cells paralleled by plasma sampling showed that there was ~60 % inhibition of firing rate—indicating significant activation of 5-HT1A receptors—at a plasma concentration of 76 nM. In line with this, we observed that sarizotan concentrations in brain homogenates were similar to total blood levels but over 500 fold higher than free extracellular fluid (ECF) concentrations as measured using brain microdialysis. These data suggest that sarizotan may have potential anti-ADHD effects at low doses free of the previously reported side-effects. Moreover, in this case a classical pharmacokinetic–pharmacodynamic relationship based on free brain concentrations seems to be less appropriate than target engagement pharmacodynamic readouts.

Full textAbstract:
Thesis advisor: Lauren SaenzStakeholder involvement is widely acknowledged to be an important aspect of program evaluation (Mertens, 2007; Greene, 2005a; Brandon, 1998). However, limited work has been done to empirically study evaluators’ practices of stakeholder involvement and ways in which stakeholder involvement is affected or guided by various factors. As evaluators interact with and place value on the input of stakeholders, social, cultural, and historical backgrounds will always be infused into the context (Mertens & Wilson, 2012; MacNeil, 2005). The field of evaluation has done little to critically examine how such contexts impact evaluators’ perceptions of stakeholders and their involvement. The present study attempts to fill these gaps, focusing specifically on the relationships among evaluator identities and characteristics, evaluation models, and stakeholder involvement. Using the frameworks of critical evaluation theory (Freeman & Vasconcelos, 2010) and a theory of capital (Bourdieu, 1986), the present study utilized a sequential explanatory mixed methods approach. A sample of 272 practicing program evaluators from the United States and Canada provided quantitative survey data, while a sample of nine evaluators provided focus group and interview data. Regression analyses and thematic content analyses were conducted. Findings from the quantitative strand included relationships between: (1) measures of individualism-collectivism and stakeholder involvement outcomes, (2) contextual evaluation variables and stakeholder involvement outcomes, (3) use of use, values or social justice branch evaluation models and stakeholder involvement outcomes, and (4) whether the evaluator identified as a person of color and the diversity of involved stakeholders. Findings from the qualitative strand demonstrated the role of dominant frameworks of evaluation serving to perpetuate systems of power. Participating evaluators revealed ways in which they feel and experience systems of power acting on them, including participation in, recognition of, and responses to oppression. The qualitative strand showed that evaluation models may be used to help recognize power dynamics, but that they are also used to reinforce existing power dynamics. Implications and recommended directions for future research are discussed

S. Marcescens ingérée par la mouche la tue en six à huit jours. Afin d'identifier les facteurs de l'hôte impliqués dans le processus infectieux, nous avons mis en oeuvre un crible compréhensif à l'échelle du génome basé sur l'interférence ARN (ARNi) in vivo dans des mouches transgéniques. Ce crible a été réalisé à Vienne en collaboration avec le groupe dirigé par le Pr. J. Penninger (IMBA, Vienne), essentiellement par Nadine Nehme et Shane Cronin. Un crible secondaire concentré sur les gènes candidats possédant des homologues chez les vertébrés et présentant un phénotype lorsque leur expression était ciblée seulement dans l'intestin moyen a permis de restreindre la liste, laquelle contenait plusieurs gènes de la voie JAK-STAT. Nous avons établi que la voie JAK-STAT contrôle le taux de prolifération des cellules souches intestinales au cours de l'infection. Pseudomonas aeruginosa tue la mouche en huit à dix jours après ingestion. La forte prolifération des bactéries dans l'hémolymphe induit les deux voies de la réponse humorale systémique, Toll et Immune Deficiency (IMD). La réponse cellulaire est aussi impliquée. Des bactéries mutants pour le gène rhIR, lequel est requis dans un système de perception du quorum sont monis virulent. La virulence des bactéries rhIR est seulement rétablit dans des mouches dépourvues de réponse cellulaire sont infectées. Nos résultats établissent que le gène rhIR est nécessaire essentiellement pour contrebalancer la seule réponse cellulaire et non la réponse humoraleS. Marcescens fed to the fly are killing in 6-8 days. To better understand the host factors implicated in the infection process we performed an ill vivo genome-wide RNAi (RNA interference) screen. This screen was realized in collaboration with the Penninger lab (Vienna). A secondary screen on the candidate genes that have vertebrate homolgs (mouse or human) was carried out using a midgut-specific driver to express the RNAi hairpin constructs. Amongst the genes that showed, in addition to the primary screen, a phenotype in the intestine specific screen, were several members of the JAK-STAT pathway. We were able to show that the JAK-STAT pathway is needed to control the level of compensatory proliferation of ISCs during the infectious process. P. Aeruginosa kills the flies within 8-\0 days upon ingestion. A strong proliferation of the bacteria in the hemolymph induces the two pathways of the humoral systemic immune response, Toll and Immune Deficiency (IMD). Phagocytosis is also needed for host defense. Bacteria mutant for the gene rhIR are less virulent. RhIR mutant bacteria just regain their virulence in flies deficient for phagocytosis. Our results show that RhIR is needed to counteract the cellular immune response, but not the humoral immune response

Full textAbstract:
The relationship between adult attachment style and romantic relationship quality in marriage relationships was explored. Romantic relationship quality was measured at the working model (or perceptual) and the behavioral levels. No previous research had investigated romantic relationship quality as reflecting specific attachment related perceptions of self and spouse or as attachment related behaviors. Two hundred and six married subjects were recruited from university campuses, churches, and on an individual basis. Most of the subjects were white, middle class, and had children. Subjects completed self-report questionnaires measuring adult attachment style, working model of self and romantic partner, and reports of relationship behaviors of self and romantic partner. The first hypothesis proposed that attachment style differences would be seen in specific attachment related working models of self and romantic partner. The second hypothesis proposed that attachment style differences would be seen in reports of attachment related behaviors for self and romantic partner. Hypotheses were tested using multivariate analysis of variance.

Full textAbstract:
A number of practitioner surveys across a range of industries have cited the lack of
senior female role models as a barrier to career progression. There is very little
academic literature to explain this at a senior organizational level. An initial review of
the extant role model literature led to the inclusion of two further related areas –
organizational demographics, as a contextual factor affecting the availability of role
models, and work identity development as a link between the lack of senior female
role models and the lack of career progression.
In seeking to answer the question of why and then how female role models are
important for senior women, this study fills an identified gap in the comprehension of
the concept of role models and their importance in the workplace. It addresses a need
to understand both the key elements of the concept and the mechanism by which they
come into play.
The research uses qualitative methods, specifically in-depth semi-structured
interviews. These were conducted with a senior group of 33 female directors from six
global investment banks, in order to elicit their experiences of role models in
demographically imbalanced work contexts.
Analysis of interview data considered all three areas of role models, demographic
context and work identity development. As the women forged their identities in the
male-dominated context of global investment banks, what became clear was that who
they are and have become was informed by the critical relationships they have had.
Whilst clearly some of the women had found male role models with whom to develop
these critical relationships, there were some identity issues, particular salient to
women, which could not be addressed by men. Thus the findings demonstrated the
utility of female role models.
This thesis has a number of contributions to make on varying levels:
On a conceptual level, this study adds to our understanding of the value of role
models, particularly detailing the affective or symbolic value. It has added to the
conceptualization of role models, detailing what were the core attributes of individuals chosen to be role models, who they were in relation to the women, how
the women used them and why they were important.
It has combined the three literature areas of role models, organizational demographics
and work identity development in a way not previously done, and has shown
empirically that they are related and explain each other. Organizational demographics
affect the availability of role models. And it is suggested that the relatively new
theory of relational identification is the mechanism that explicates how the presence
of positive female role models is a key influence on women’s work identity
development.
It has clarified the value of role models in extreme gender demographic contexts, and
how and why they are important to senior women’s professional development, thereby
adding to the theory of role modelling.
Practically, the study explains why women in surveys may have been citing the lack
of female role models as such a prominent issue, and suggests what some of the issues

Full textAbstract:
This study examined models of self and other as they relate to attachment, forgiveness, emotional and cognitive reactions to a breakup, relationship variables, and positive and negative feelings toward the self and former partner after a romantic relationship is ended. This study also tested how these variables change over time. Data were collected over a period of five weeks from 130 undergraduates who had experienced a breakup within the two weeks prior to beginning the study. Data were analyzed with a series of univariate and multivariate analyses of variance. Results found that there were differences in how participants reacted to the relationship breakup based on attachment style. There were some changes over time in the variables for all the attachment styles, and there was only one interaction between time and attachment style. Results are discussed in terms of previous research findings. Limitations of the current study are discussed and suggestions for future research are presented.

Full textAbstract:
[Truncated abstract] The aim of this research was to define key species-environment relationships to better understand the spatial ecology of demersal fish. To help understand these relationships a combination of multivariate analyses, landscape analysis and species distribution models were employed. Of particular interest was to establish the scale at which these species respond to their environment. With recent high resolution surveying and mapping of the benthos in five of Victoria's Marine National Parks (MNPs), full coverage bathymetry, terrain data and accurate predicted benthic habitat maps were available for each of these parks. This information proved invaluable to this research, providing detailed (1:25,000) benthic environmental data, which facilitated the development and implementation of a very targeted and robust sampling strategy for the demersal fish at Cape Howe MNP. The sampling strategy was designed to provide good spatial coverage of the park and to represent the park's dominant substrate types and benthic communities, whilst also satisfying the assumptions of the statistical and spatial analyses applied. The fish assemblage data was collected using baited remote underwater stereo-video systems (stereo- BRUVS), with a total of 237 one-hour drops collected. Analysis of the video footage identified 77 species belonging to 40 families with a total of 14,449 individual fish recorded. ... This research revealed that the statistical modelling techniques employed provided an accurate means for predicting species distributions. These predicted distributions will allow for more effective management of these species by providing a robust and spatially explicit map of their current distribution enabling the identification and prediction of future changes in these species distributions. This research demonstrated the importance of the benthic environment on the spatial distribution of demersal fish. The results revealed that different species responded to different scales of investigation and that all scales must be ix considered to establish the factors fish are responding to and the strength and nature of this response. Having individual, continuous and spatially explicit environmental measures provided a significant advantage over traditional measures that group environmental and biological factors into 'habitat type'. It enabled better identification of individual factors, or correlates, driving the distribution of demersal fish. The environmental and biological measures were found to be of ecological relevance to the species and the scale of investigation and offered a more informative description of the distributions of the species examined. The use of species distribution modelling provided a robust means for the characterisation of the nature and strength of these relationships. In addition, it enabled species distributions to be predicted accurately across unsampled locations. Outcomes of the project include a greater understanding of how the benthic environment influences the distribution of demersal fish and demonstrates a suite of robust and useful marine species distribution tools that may be used by researcher and managers to understand, monitor, manage and predict marine species distributions.

Full textAbstract:
This dissertation is structured around three original studies that offer unique insights into the challenges of change in business-to-business markets. All three studies share as an important starting point that firms rely on other firms to achieve strategic flexibility in volatile business environments. This means that firms source critical resources from business relationships in order to reduce long-term investments in times of change. From this perspective, firms' competitive advantages cross the boundaries of the firm and are embedded in their business partner networks. Thus, firms' business relationships and networks have become an important locus of organizational change in order to respond to turbulence in firms' business environments. Study one of this dissertation recognizes the importance of supplier relationships as a mechanism to react to changing business environments. The article focuses on the dynamic capabilities that enable firms to structurally reconfigure their supplier portfolios or supply networks in order to access necessary resources. The framework of relationship management capabilities introduced, is structured around three important sub-dimensions: relationship initiation, development, and ending capabilities, which collectively enable a firm to manage the reconfiguration of resource portfolios accessed via supplier relationships. The key implication for management relates to thinking beyond firms' established supply chains in times of change. While to a certain degree change can be absorbed within firms' existing supply chains, there might be a need to be 'agile', i.e. search for other suppliers who are better suited to more efficiently and effectively address such changes affecting firm competitiveness in the long run. While study one highlights the importance of firms' agility in adapting their supply chains in response to changes in their business environment, study two of this dissertation, although with a focus on the demand side of the business model, addresses the managerial challenges associated with such an agile adaptation process. Study two conceptualizes a framework for business model change and provides managers guidance to approach business model redesign. In particular, study two focuses on service business models and introduces the concepts of service infusion and defusion as important processes of business model redesign. The service infusion and defusion framework provides a pragmatic and systematic approach to understanding the nature of the business model change that companies have to manage, as well as linking these changes with knowledge creation and transfer processes. These are shown to be key for successfully managing such a business model redesign. While studies one and two assume strategy and its implementation to be key to a successful response to changes in firms' business environment, study three draws attention to the difficulties of arriving at such an appropriate or fitting response strategy in the first place, given the available information. In particular, this study examines the link between sensing changes in firms' business environments and managerial decision making in the form of strategy choice. Thereby, the study shows that strategy change causes disruptions, which eventually affect firm performance. This effect is compounded with increasing sensitivity to change as well as increasing number of factors that trigger change, and thus impairs the long term benefits of such strategy change. Thus, the effectiveness of strategy or business model changes and their implementation is inevitably contingent on distinguishing key signals from noise that disturb or misguide firms' strategic decisions.

Full textAbstract:
Scholars have long been interested in the complex relationships between personality and motivation. However, much of their understanding has been limited to The Big Five personality factors (namely, Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism), and a proliferation of motivation constructs emanating from a large number of different theories and sub-theories. This study adds to the body of personality psychology and motivation science literature by examining the relationships between The Big Five personality factors and The MUSIC Model of Academic Motivation (MMAM) components (i.e., eMpowerment, Usefulness, Success, Interest, and Caring). The MMAM is comprised of five components that summarize the many instructional implications derived from motivation theories and research to provide instructors with a holistic, conceptual understanding of them. The results of this study may provide evidence as to whether or not the personality traits of college students influence their academic motivation beliefs. To obtain data, I surveyed college students using two self-report instruments. The first instrument, the Big Five Inventory (BFI), measured college students on The Big Five personality factors. The second instrument, the MUSIC Model of Academic Motivation Inventory (MMAMI), measured the academic motivation beliefs of college students as related to the MMAM. Data were obtained from 305 college students at a single university in southwest Virginia enrolled in an online course. Exploratory Factory Analysis (EFA) and Confirmatory Factor Analysis (CFA) using Structural Equation Modeling (SEM) were used to answer the following research question: To what extent do the Five Factor Model factors relate to the MMAM components? Due to the lack of substantiated knowledge regarding the relationships between The Big Five personality factors and the MMAM components, specific hypotheses were not generated. The measurement models for the Big Five personality factors and the MMAM fit well. However, the structural model, in which the Big Five factors were modeled to predict the MMAM components, did not adequately fit the data for these college students. Yet, there were a number of significant pathways between The Big Five personality factors and the MMAM components. Openness and Conscientiousness had a significant, negative impact on eMpowerment, while Extraversion had a significant, positive impact on eMpowerment, Usefulness, and Interest. Additionally, Agreeableness had a significant, positive impact on Usefulness, Success, Interest, and Caring, while Neuroticism had a significant, negative impact on Success.
Findings indicated that personality factors can relate to or predict academic motivation. In other words, students' academic motivation beliefs are, to a certain degree, influenced by some of their personality traits, and these differences in traits may manifest themselves in the classroom. In the future, researchers could examine the extent to which students with different personality traits display varying preferences as to the types of pedagogical methods or strategies that motivate them academically.Ph.

Full textAbstract:
Tese de Doutoramento em Ciências Veterinárias na Especialidade de ClínicaThe human-dog dyad is thought to be the oldest existing domestic partnership and is generally mutually beneficial for both members of the partnership. Dysfunction in the human-dog dyad, however, produces serious consequences for each member of the partnership and also for society at large. Research into these relationships has addressed only the consequences of dysfunction, making prevention difficult. This project set out to evaluate the possibility of pre-emptively identifying dysfunction in such dyads by using dog health histories easily available in clinical contexts. To that end, the researcher developed a simple, one-page questionnaire that was disseminated in the greater metropolitan areas of Lisbon, Portugal, and was made available online. By identifying a dog’s biting history, trauma, or involvement in a vehicular accident, the researcher was able to suggest the possibility of the dog’s involvement in a dysfunctional dyad. To classify the canine behaviour traits essential for establishing the general characteristics of dysfunctional dyads, the researcher developed the European Portuguese Canine Behaviour Assessment and Research Questionnaire (C-BARQ). The psychometric properties were evaluated, and the instrument showed excellent to respectable consistency. The result was a canine behavioural questionnaire that established 13 different personality traits. A more extensive questionnaire was then administered to the same population in Lisbon, Portugal, aimed at identifying husbandry and noting dog and human characteristics within dysfunctional dyads. The results suggest that dogs housed on verandas or on plots of land, dogs that were fed diets purchased at agricultural cooperatives, dogs with C-BARQ scores showing high owner-directed aggression (ODA), dog-directed agressoion/fear (DAF) and dog rivalry (DR) were more likely to be part of dysfunctional dyads. Similarly, owners with high neuroticism scores and low lie/social desirability scores on the Eysenck Personality Questionnaire (EPQ-R) were also more likely to be part of these partnerships. These characteristics were then used to develop two predicative models – the Predicted Dysfunction with Dog and Owner Characteristics (PDDOC) and the Predicted Dysfunction with Dog Characteristics (PDDC) – that successfully predicted dysfunction in 79.7% and 80.1% of cases respectively. These findings reveal the feasibility of pre-emptively identifying dysfunctional human-dog dyads. As a result, this pre-emptive identification can be used to take preventative action – specifically the development of educational programs, the improvement of human-dog pairings, and the equipping of veterinarians to better prevent and/or correct dysfunction.
RESUMO - A díade homem-cão é considerada a mais antiga parceria doméstica, sendo tida como mutualmente benéfica para ambos os membros. Quando estas díades se tornam disfuncionais pode haver sérias consequências, não apenas para os membros da díade, mas para a sociedade no seu todo. A disfuncionalidade de díades tem sido abordada em diversos estudos, contudo somente após se terem sentido as suas consequências nefastas, o que dificulta o processo de implementação de medidas preventivas. Este projecto teve como objetivo a sua identificação precoce, usando para isso, o historial de saúde do animal disponibilizado em contexto clínico. Foi desenvolvido um questionário sucinto de uma página, o qual foi distribuído a proprietários em Centros de Atendimento Médico-Veterinário (CAMV) na Área Metropolitana de Lisboa e também em formato online. A identificação de ocorrência de mordedura, trauma ou atropelamento foi associado a díade disfuncional. Foi desenvolvido o European Portuguese Canine Behaviour Assessment and Research Questionnaire – C-BARQ (Questionário de Investigação e Avaliação de Comportamento Canino) com o intuito de estabelecer bases gerais que permitissem classificar alguns aspetos do comportamento canino. Avaliaram-se as propriedades psicométricas e o instrumento mostrou um intervalo de consistência do respeitável ao excelente. O resultado final foi um questionário de comportamento canino que estabeleceu 13 traços de personalidade diferentes. Administrou-se seguidamente um questionário mais extenso à mesma população, mas agora com a finalidade de identificar características tanto do homem como do cão nestas díades disfuncionais. Observou-se que cães alojados em varandas ou em terrenos, alimentados com rações compradas em cooperativas agrícolas ou que apresentaram valores elevados nos scores de ODA, DAF e DR no C-BARQ, têm uma maior tendência de fazer parte de uma díade disfuncional. Proprietários que no questionário de personalidade humana, EPQ-R apresentaram um valor elevado em neuroticismo e baixo em mentira/desejabilidade social também partilham esta tendência. Estas características foram então usadas no desenvolvimento de dois modelos preditivos (PDDOC e PDDC), cujos resultados previram disfunções em 79,7% e 80,1% dos casos, respetivamente. Estes resultados, possibilitarão o desenvolvimento de programas educacionais, escolha mais informada na adoção de animais em abrigos, bem como dar aos médicos veterinários ferramentas para identificar e eventualmente prevenir e/ou corrigir algumas destas disfunções.

Full textAbstract:
This thesis introduces new theoretical models and concepts in support of strategic thinking about the dynamics and complexities of organisational relationship positioning that could improve public relations education and professional development linked to strategic management careers in international organisations. An exploration of public relations in the United Kingdom and Nigeria illustrates that there is a significant practice mainly concerned with communication that develops strategies and tactics in support of already established strategic organisational goals. Progress with professionalisation of the practice also shows an increasing need and want to operate at senior management levels, although it questions if the academic preparation to do so is adequate. Advances in communication technology and education approaches provide opportunities to better understand complex networks and relationships. The emphasis in this thesis is on strategic planning. Most frequently used tools and approaches are briefly discussed. They are mainly descriptive and often provide snapshots of current situations that can help with formulating a future desired situation. Most of these tools and approaches expand the brainstorming horizon providing opportunities for vertical (deeper) and horizontal (broader) thinking about organisational relationships. This thesis introduces additional models, namely the revised public relations catalyst model and the public relations lava lamp model, and concepts such as organisational personality that could be used to further the strategic thinking about the dynamics of such relationships. The new insights and perspectives on strategic planning presented here stem from qualitative explorative research based on observations and interpretations from applying strategic thinking exercises in seminars at the University of Central Lancashire, and from action research approaches by leading strategic planning and organisational change activities at the International Institute of Tropical Agriculture (IITA) which involved in-depth interviews, workgroup sessions and online questionnaires. Positioning of organisational relationships is an increasingly important function of strategic management in international organisations such as IITA. This is driven by pressure for more engagement, transparency and accountability by public investors and partners related to providing the essential resource base in terms of finance and implementation capacity essential for the organisation’s existence. Improving strategic planning competences relating organisational relationships not only provides opportunities for public relations practitioners to be part of senior management but also is essential for an organisation’s continuity and relevance. It was found that strategic thinking improves by stimulating both vertical and horizontal thinking about initial surface problems. Problem based learning approaches in public relations education should be considered as they can help prepare future practitioners to improve their strategic planning competences. Advances in communication technology have the potential to maintain and improve organisational relationships far beyond current organisational network boundaries and creates opportunities for advancing strategic thinking and planning. Logical framework planning and other problem-based tools can help to identify solutions for a central problem. However, they require the facilitation of planning teams with different personalities that are encouraged to think deeper and wider to ensure that alternative solutions are considered and that enough cause-effect relationships are established for strategic interventions to be successful. The use of the lava lamp metaphor also stimulates strategic thinking about the dynamics of organisational relationships aided by different perspectives that stimulate vertical and horizontal thinking. The concept of organisational personality has potential to identify which organisations would be potential collaborators in finding better solutions and help to understand potential relationship issues better.

Parental self-efficacy impacts the manner in which a parent interacts with his or her child, as well as child development. Parental self-efficacy can be influenced by a variety of parent and child characteristics, in addition to contextual factors such as socioeconomic status. Parents of children with autism are at risk for lower self-efficacy due to a number of additional influences, including stress, autism severity, and how professional supports are provided. The purpose of this study is to investigate the relationship between maternal self-efficacy in mothers of children with autism and parent-professional relationships, the instructional techniques utilized in parent training, parenting stress, socioeconomic status, and parents’ perceptions of child progress. A sample of 43 mothers in British Columbia whose children with autism were receiving services from a behavior consultant completed The Early Intervention Parent Questionnaire (EIPQ) that was developed for this study. The EIPQ measures maternal self-efficacy and the variables believed to influence maternal self-efficacy. A regression analysis found that parenting stress and parents’ perceptions of child progress were related equally to maternal self efficacy. Implications are discussed, with suggestions for future research.

Full textAbstract:
Assignment (MAcc )--University of Stellenbosch, 2002.ENGLISH ABSTRACT: The price-earnings ratio is one of a series of benchmarks developed after the Great Depression, to measure the fair value of shares on a relative basis. It originated from the idea that investors buy the earnings of a company and that the price-earnings ratio provides a consensus indication of the future growth potential of a company. Therefore, the price-earnings ratio is a rating of a company's future profitability. The price-earnings ratio developed, over the years, firstly, into an indicator of the relative risk associated with a company as the market anomalies associated with the ratio were investigated and clarified, and the theoretical background of the ratio integrated with the portfolio theory. It is now clear that the price-earnings ratio can be a useful indicator of the risk associated with an investment and the uncertainty associated with the duration of the growth phase of a company. Secondly, the price-earnings ratio is also a growth and valuation model with a theoretical background that can be linked to popular dividend discount models and the growth opportunities approach to investment valuation. With the use of the price-earnings ratio it is easy to visualise the relative profitability and the total investment required to raise a company's rating of future profitability. This simplicity allows one the opportunity to evaluate the reasonableness and likelihood of the investment reaching its projected potential profit targets. Lastly, as a result of accounting changes and the different accounting rules in force today, the price-earnings ratio also assists in the identification and elimination of the effects of accounting on investment decisions. It is apparent that the price-earnings ratio possesses the capabilities to assist investors significantly with the analysis of investment opportunities.
AFRIKAANSE OPSOMMING: Die prys-verdienste verhouding is een van 'n reeks relatiewe maatstawwe ontwikkel na die Groot Depressie om die redelike waarde van aandele te bepaal. Dit is gebaseer op die idee dat beleggers die winste van 'n maatskappy koop en dat die prys-verdienste verhouding 'n konsensus aanduiding verskaf van die toekomstige groeipotensiaal van 'n maatskappy. As gevolg hiervan is die prys-verdienste verhouding 'n aanduiding van die relatiewe toekomstige winsgewendheid van 'n maatskappy. Die prys-verdienste verhouding het oor die jare ontwikkel, eerstens as 'n aanwyser van die relatiewe risiko verbonde aan 'n maatskappy soos abnormaliteite wat daaraan verwant is ondersoek en verklaar is, en die teorieë onderliggend aan die verhouding ontwikkel het saam met die portefeulje teorie. Dit is nou duidelik dat die prys-verdienste verhouding 'n bruikbare aanduider is van die risiko wat geassosieer word met 'n belegging en die onsekerheid wat gepaard gaan met die duur van die groeifase van 'n maatskappy. Tweedens is die prys-verdienste verhouding ook 'n waardasie- en groeimodel met 'n teoretiese agtergrond wat verband hou met die populêre dividend verdiskonteringsmodelle en die groeigeleenthede-benadering tot waardasie. Met die gebruik van die prys-verdienste verhouding is dit maklik om die relatiewe winsgewendheid en die totale belegging wat benodig word om die waarde van die relatiewe winsgewendheid van 'n maatskappy te verhoog, tevisualiseer. Hierdie eenvoud verskaf die geleentheid om die redelikheid en die waarskynlikheid van 'n belegging om sy voorsiene winsgewendheidsdoelwitte te bereik, te evalueer. Laastens, as 'n resultaat van die rekeningkundige veranderinge, en die verskillende rekeningundige reëls huidiglik van toepassing in die wêreld, help die prys-verdienste verhouding ook met die identifikasie en die eliminasie van rekeningkundige komplikasies op beleggingsbesluite. Dit is duidelik dat die prys-verdienste verhouding die vermoë het om die belegger by te staan met die ontleding van beleggingsgeleenthede.

Full textAbstract:
A model of parental sensitivity in caregiving informs later romantic relationships and is transmitted in caregiving behaviours to children. Differences in parental caregiving contribute to individual differences in infant attachment style. The owner/dog bond mirrors this relationship as dog careseeking activates owner caregiving. The aim of this thesis was to investigate the role of individual differences in owner caregiving on dog attachment style. The first study defined dog attachment style in the Strange Situation Test (Ainsworth & Wittig, 1973) in a sample of 52 self-selected owner/dog dyads. Dogs seek proximity, show evidence of distress when separated and use owners as safe havens for exploration. Individual differences in attachment security and insecurity were found. Secure dogs achieve attachment system deactivation through owner contact. Insecure dogs’ attachment systems remains activated with: excessive focus on the owner but otherwise behaviourally passive; excessive owner avoidance focussing on evading the owner; or anxiety, consisting of high distress which could not be pacified by owner. The second and third studies tested the effects of owner behaviour on individual differences in dog attachment style and exploratory system activation in a task-solving experiment. Behaviours assessed were talk and touch durations in the Strange Situation and owner “frightening” behaviours (threatening; owner showing fear; dissociation; disorganised; highly submissive; and sexualised behaviours). Owner behaviours significantly related to dog attachment style: owners of Avoidant dogs petted them less, talked to them more and used frightening behaviours, whereas, owners of Secure dogs used moderation in talk and touch and few frightening behaviours. Secure dogs task-solved longer and their owners were significantly less invasive and controlling (grabbing paws, restraining dogs) than owners of Avoidant dogs. Owner sensitivity is therefore related to dog attachment security which enables exploratory system activation. Self-reports of owner attachment style in the fourth study found a trend towards a dismissive style in adult relationships and dog avoidance. Parent/child studies have linked parental frightening behaviours to subsequent infant disorganisation (due to the secure base or safe haven also being the source of fear), and to parental unresolved loss, trauma or abuse. Using interview protocols, studies five and six found relationships between owners Unresolved in loss, a Dismissive owner working model, invasive owner task solving behaviour, frightening owner behaviours and Avoidant dog attachment, indicating of a web of interaction between working models and behaviour. The results indicate the potential effects of owner behaviour on the human/dog bond. The results could be used in assessing owner dog relationships that may indicate risk of animal/human abuse; assist dog shelters in the successful re-homing of insecure dogs by identifying secure households; and to enable greater owner understanding of dog behaviour and appropriate responding leading to more satisfying human/dog bonds, and thus fewer relinquishments to shelters.

Full textAbstract:
This thesis examines the concept of teachers acting as moral models in education and how the role of empathy in teacher-pupil relationships plays a part in this process. In particular it examines how teachers understood these issues and whether those same understandings could be seen at work in classroom practice. The thesis integrates the traditional literature in this field with recent research into neuroscience. This combination highlights the effect of emotion on engagement in learning, decision-making and a sense of attachment and responsibility in interaction and relationships. Following a pilot study and exploratory work with both methodology and subject, grounded theory was chosen as the methodology and a conceptual framework was created from the data. Empathic teachers and student teachers were interviewed and observed, in different contexts in both primary and secondary phases, including teachers who support special needs students and students of English as another Language. The thesis presents a detailed exposition and classification of empathy at work in teaching and learning. Empathy is revealed as a highly complex phenomenon, which develops over time and with frequency of interaction and which is highly dependent on the actors and the context of the interaction. The thesis confirms and expands the powerful effects of profound empathy on self-esteem, relationships and learning. Empathic teachers are revealed as highly moral individuals who attach themselves mentally and emotionally to their pupils generating similar responses in return, in effect modelling and evoking morality in their personal interactions with pupils and colleagues. Positive personal interaction supports high quality learning, engagement and behaviour in valuing relationships. This has implications for both face to face and e-learning. However, the constraints of class size, time, curriculum, policy and management distort the moral model offered by teachers. These constraints are conditioned to a large extent by economic and competitive considerations. The thesis identifies a phenomenon entitled functional empathy, which teachers use to create mental connections with whole classes. Functional empathy is of a lower moral order and in conjunction with shallow levels of personal empathy and feigned empathy has implications for the moral model offered to large numbers of students, throughout their education. The thesis therefore has significant implications for the moral order in general.

Full textAbstract:
The purpose of this study was to examine the possible mediating effect of self-esteem on the relationship between attachment security and relationship quality. Previous studies have found a positive association between attachment style and relationship quality. One possible explanation for this link may be self-esteem, which has been shown to consistently predict relationship quality. Therefore, I hypothesized that self-esteem may mediate the relationship between attachment and relationship quality. A sample of 680 married couples that completed the sections on attachment, self-esteem, marital satisfaction, marital stability, and problem areas in the relationship of the RELATE questionnaire between 2011 and 2013 was used. The data were analyzed using an Actor-Partner Interdependence Model (APIM) to help account for shared variance. Results found that there is a positive link between one's attachment and their level of self-esteem and their own relationship quality. However, results also found negative trend-level effects for the links between attachment and partner's level of self-esteem and self-esteem and own relationship quality. There was no mediating effect of self-esteem on the relationship between attachment and relationship quality.

Full textAbstract:
The adsorption behaviour of trace metals in soil may provide us with a way to more accurately predict and assess the toxicity of metals in the environment. This thesis reports efforts to apply surface complexation modeling to agricultural and forest soil and to relate model parameters to common soil properties. This study considered Ca, Cd, Cu, Pb and Zn but the methods here could be applied to other metals. In Chapter 2, the surface charge and adsorption behaviour of a set of Ap horizons was characterised using back-titration and batch adsorption techniques. With the objective of simplifying the application of the NICCA model to surface charge and cation adsorption in whole soils the parameters of the NICCA model were related to soil properties (Chapter 3). Four of the six surface charge parameters could be predicted from soil properties and this enabled me to reasonably predict the surface charge of a second group of soils from soil properties. These results suggest that it is possible to make reasonable predictions about the surface charge and adsorption behaviour of a given type of soil using some easily measurable soil properties and a set of generic NICCA adsorption parameters for that soil type. In Chapter 4 this idea is applied to the determination of lime requirement for the agricultural soils.

La tesis trata de los modelos de gestión modernos de naturaleza causal, entre los que destaca el Cuadro de Mando Integral (CMI). En primer lugar, se presenta un análisis conceptual su supuesto central, las relaciones causa-efecto. En segundo lugar, se ofrece un análisis estadístico de los supuestos del CMI. En tercer lugar, a partir dos casos de estudio de ayuntamientos, se compara y analiza la implementación del CMI en las organizaciones. El análisis conceptual indica que la complejidad, la incertidumbre y el carácter dinámico del entorno pueden obstaculizar la elaboración de modelos válidos de causa-efecto. Los resultados del análisis estadístico no permiten confirmar la hipótesis de existencia de relaciones estables en el CMI. Finalmente, el análisis de los casos sugiere que las organizaciones pueden recurrir a diversas tácticas y escenarios para implementar el CMI y enfatiza la influencia que las rutinas y normas establecidas en las organizaciones ejercen en ello.This dissertation address a number of research questions related to causal performance measurement models, such as the Balanced Scorecard (BSC). First, we provide an analytical discussion on the topic of the cause-and-effect relationships in these models. Second, we test of the BSC assumptions on empirical data coming from the dynamic enterprises. Third, we compare and analyze the BSC adoption by two city councils. The conceptual analysis indicates that dynamic, complex and uncertain environment and the cognitive limitations of managers may greatly challenge the elaboration of valid causal models. Our statistical results give little support to the existence of stable BSC links. Our case studies findings show diverse organizational rationalities behind the BSC adoption in organizations and the importance of the existing rules and routines.

Self-thinning quantifies the reduction in tree numbers due to density-dependent mortality. Maximum size-density relationships (MSDRs) are a component of self-thinning that describe the maximum tree density per unit area obtainable for a given average tree size, often quadratic mean diameter (D). An MSDR species boundary line has been defined as a static upper limit of maximum tree density -- D relationships that applies to all stands of a certain species within a particular geographical area. MSDR dynamic thinning lines have been defined as the maximum tree density obtainable within an individual stand for a particular D which have been shown to vary relative to planting density. Results from this study show that differences in boundary levels of individual stands cause the MSDR species boundary line slope estimate to be sensitive to the range of planting densities within the model fitting dataset. Thus, a second MSDR species boundary line was defined whose slope is the average slope of all MSDR dynamic thinning lines. Mixed-models are presented as a statistical method to obtain an estimate of the population average MSDR dynamic thinning line slope.
A common problem when modeling self-thinning is to determine what observations are within generally accepted stages of stand development. Segmented regression is presented as a statistical and less subjective method to determine what observations are within various stages of stand development. Estimates of D and trees per acre (N) where MSDR dynamic thinning lines begin and end on the logarithmic scale were used as response variables and predicted as a function of planting density. Predictions of MSDR dynamic thinning line beginning and ending D and N are used in an alternative MSDR dynamic thinning line slope estimation method. These models show that the maximum value of Reineke's Stand Density Index (SDI) varies relative to planting density.
By relating planting density specific Zone of Imminent Competition Mortality boundaries to a MSDR species boundary line, self-thinning was found not to begin at a constant relative SDI. Thus, planting density specific Density Management Diagrams (DMD) showed that self-thinning began at 40 to 72% for planting densities of 605 and 2722 seedlings per acre, respectively.Ph. D.

Full textAbstract:
Sinkholes are a significant hazard for the southeastern United States. Although differences in climate are known to affect karst environments differently, quantitative analyses correlating sinkhole formation with climate variables is lacking. A temporal linear regression for Florida sinkholes and two modeled regressions for Tennessee sinkholes were produced: a general linearized logistic regression and a MaxEnt derived species distribution model. Temporal results showed highly significant correlations with precipitation, teleconnection patterns, temperature, and CO2, while spatial results showed highly significant correlations with precipitation, wind speed, solar radiation, and maximum temperature. Regression results indicated that some sinkhole formation variability could be explained by these climatological patterns and could possibly be used to help predict when/where sinkholes may form in the future.
