The most important questions we ask are normative questions. And the most fundamental normative questions are couched in terms of reasons: What do I have reason to do? and What do I have reason to believe? Although not always explicitly about reasons, I take it that much of normative philosophy at least implicitly offers first order normative answers to such questions. But stepping back, we can ask what these questions and answers are about - what are reasons anyway? This dissertation addresses those meta-normative questions, questions about the conceptual structure, semantics, ontology and epistemology of reasons. In the inquiry to come, chapters 1 and 2 consider the conceptual structure and core semantics of reasons. I argue that all reasons-internal reasons grounded in motivational states, external reasons connected to morality, epistemic reasons for belief, whatever--share the same conceptual structure and core semantics, so they all will stand or fall together when it comes to questions of reason truths and facts. In chapters 3-5 I argue that reason discourse has realist purport because reason judgments feature cognitive and belief-like attitudes about the way the world is, normatively speaking. To vindicate normativity's realist purport would require an ontology of favoring relations flowing from considerations in the world to actions and attitudes of various agents. So in chapters 6 and 7 I consider such an ontology. Unfortunately, favoring relations do not fit into the emerging naturalized view of the world. To make matters worse, based on the kinds of reasons we accept, there are no good reasons for admitting non-natural favoring relations in to the ontology. Reasons cannot bear their own survey. As a result, this dissertation culminates in a revisionary semantics, discussed in chapter 8, whereby I suggest we all adopt a fictive stance toward propositions about any kind of reason. In the end, we can preserve reason discourse and its characteristic roles in our lives so long as we are disposed to avow irrealism about reasons in critical contexts.

Proceduralists about practical rationality and reasons for action argue that practical rationality is only capable of criticizing our reasons for action when, through deliberation, they are reachable through our current beliefs and desires. Using this model of practical rationality, proceduralists also typically argue that the only reasons for action we have are instrumentally valuable ones. Substantivists disagree, however, and argue that practical rationality is capable of criticizing our actions despite our desires, preferences and interests. Substantivists argue that although we have instrumental reasons for action, there are also other reasons for action we have, specific non-instrumental ones, which we are required to act for on pain of irrationality. In this thesis I argue that a substantivist model of practical rationality and reasons for action is correct, and that understanding practical rationality and reasons for action in this way has surprising consequences for moral theory.

There is a clear call to use evidence-based practice (EBP) in schools, and a growing knowledge base of practices that have proven to be effective in helping students achieve in educational settings. In addition, the current trends of Positive Behavior Supports (PBS) and Response to Intervention (RtI) advocate for preventative and proactive strategies. Token economies (TE) are one intervention that is proactive and can be flexible to use with students across a wide range of behaviors and settings. According to Higgins, Williams, and McLaughlin, token economy (TE) is an effective way to improve classroom behavior. Unfortunately, limited recent research is available that evaluated the effects and moderators of token economies in classroom settings. The purpose of this investigation was to Meta-analyze the single case research on TE implemented in school and is the first to offer effect size analysis and identify moderators. The use of TE's has been widely established as an evidence-based intervention for use in prisons, psychiatric hospitals, and school settings. However, very few articles discuss size of effects to expect, the essential elements required, or the practical implementation issues within a classroom. Many myths surround the use of a TE, i.e., many assume a token system is effective only for individuals and this is not so, as TE is effective for groups as well as individuals. In an age of accountability and emphasis on preventative evidence based practice evidence for using a TE and how to implement a TE is needed in our literature. Empirical evidence for the use of a token economy in a classroom is presented along with suggested implementation ideas. Twenty four studies were included in this Meta-analysis with an overall combined Tau-U ES of .78 of data showing improvement between phase A and B with CI90 [.72, .83]. Tau-U effect sizes ranged from .35 to 1.0. TE is effective with all ages evaluated (ages 3 - 15); however, statistically significant results indicated it was more effective with ages 6 - 15. Active ingredients (i.e. procedural steps) were evaluated, combined, and reported. Results indicate that TE is an evidence-based intervention to increase academic readiness behaviors and to decrease inappropriate behaviors.

Ant Colony Optimization is a relatively new meta-heuristic that has proven its quality and versatility on various combinatorial optimization problems such as the traveling salesman problem, the vehicle routing problem and the job shop scheduling problem. The paper introduces an Ant Colony Optimization approach to solve the problem of determining a job-sequence that minimizes the overall tardiness for a given set of jobs to be processed on a single, continuously available machine, the Single Machine Total Tardiness Problem. We experiment with various heuristic information as well as with variants for local search. Experiments with 250 benchmark problems with 50 and 100 jobs illustrate that Ant Colony Optimization is an adequate method to tackle the SMTTP.

The purpose of this dissertation was to determine the concepts, characteristics, and variables addressed in other dissertations deemed highly relevant to the literature on adult faith development. The principle contribution of this dissertation was a 44-page matrix and an accompanying 29-page index that reveal the "Primary" and "Secondary" concepts addressed in these other documents. The study employed meta-analytical techniques to design this pictorial tool for future faith development researchers.A search for the keyword "faith development" on the CD-ROM Dissertation Abstracts database yielded 141 documents written from 1980-1994. One hundred and thirty-six abstracts were obtainable for review. Based on these abstracts and aided by a second reader, the author deemed 60 dissertations as being highly relevant to the adult faith development literature. These dissertations were then ordered via interlibrary loan for further analysis of their concepts, etc.Following the pilot study, a decision was made to include an analysis of the dissertations in terms of three tpes of classification. A classification code was assigned to all 60 dissertations in terms of their "Type of Research," "Type of Methodology," and "Type of (Religious) Tradition."Over 900 "Primary" and "Secondary" concepts, etc., were gleaned from the 60 documents. Using Spradley's ethnographic technique of organizing concepts, the concepts were arranged in 35 clusters. The clusters were tallied in 10 possible ways.The results suggest that the dissertations were fairly balanced in terms of those which constituted "Application" research and "Theoretical" research. The most frequently used methodology was "Creative Project," followed by "Qualitative" methods. The vast majority of dissertations were written from the "Protestant" tradition, followed by "Catholic," and "Other."Of the 35 clusters of concepts, etc., analyzed, the results suggest a gap in doctoral research in terms of studies pertaining to concepts related to "Transcendence," "Symbolism," "Evangelism," and "Gender." Much "Secondary" emphasis has been give to concepts, etc., related to "Devotional" but this cluster was not of "Primary" emphasis in any of the 60 studies. The work of faith development pioneer James W. Fowler was of "Primary" emphasis in 37 of the 60 dissertations. / Department of Educational Leadership

With the growing number of older adults in the general population, there is also a concomitant rise in the number of older adults who require mental health services, making the measurement of psychological conditions in later life a priority. However, due to a lack of measures created for older adults, researchers and clinicians must often rely on measures created for younger populations. Three studies were designed to add to the field of evidence-based assessment and determine which anxiety measures possess strong evidence when used with older adults to warrant their use with this specific population. In the first study, I systematically reviewed the literature to identify the anxiety measures most commonly used with older adults. I reviewed each measure to examine its psychometric properties (e.g., internal consistency, test-retest reliability, inter-rater reliability, concurrent and discriminant validity) and the availability of age-appropriate norms in order to evaluate whether the instruments are appropriate for use with older adults. In the second study, I conducted a reliability generalization meta-analysis to estimate the mean reliability of each commonly used anxiety measure identified in the first study. Finally, in the third study, I examined whether the anxiety measures commonly used with an older population can be consistently and accurately categorized as evidence-based. The literature review and the reliability generalization study both revealed that most of the most commonly used measures lacked sufficient evidence to warrant their use with older adults. However, three measures (Beck Anxiety Inventory, Penn State Worry Questionnaire, and Geriatric Mental Status Examination) showed psychometric properties sufficient to justify the use of these instruments when assessing anxiety in older adults. In addition, two measures developed specifically for older adults (Worry Scale and Geriatric Anxiety Inventory) were also found to be appropriate for use with older adults. This suggests that based on their overall level of reliability and previous psychometric evidence, both researchers and clinicians assessing anxiety in a geriatric population should consider these measures as likely to be the best currently available.

The thesis develops new understanding in relation to Outdoor Management Development (OMD). The argument is in three parts. Part One reviews notions of management development within which OMD is conventionally located. It underlines the powerful influence of a modernistic positivistic-objectivist methodological paradigm in much of the OMD commentary, manifesting itself as an objectivised corporate imperative of optimum effectiveness and efficiency. Complementary critical perspective paradigms are introduced including comments on narrative and social construction. In relation to this context, the argument presents a contemporary set of images sourced from prima facie conceptualisations of the OMD domain. Part Two considers possibilities for revisiting the contextualisation of OMD. This is undertaken through a contemporaneous and diachronic look at OMD. This involves a novel debate on the "origins" of OMD and comments on the neglected influences important to how individuals construct narrative. Certain narrative accounts in OMD writing are reviewed. These are shown to be very influenced by the predominant positivist paradigm. The third and final Part of the argument presents: Methodology, Stories and Conclusion. The debate develops a qualitative participant observer approach that facilitates the writing of narratives that underline the reflexive and deeply personal experience that the research involves. The Stories are accompanied by reflective commentaries. The argument concludes and contributes a number of points. The contemporaneous conceptualisation of OMD is positivistic and this is a consequence of its close association with modernistic perspectives of management thinking. Also, modernistic meta-narratives have been apparent in the historical accounts in the field. Consequently, stoned and narrative accounts have been marginalised but where written they are imbued with positivism also. Bearing the above in mind the thesis writes fresh socially constructive accounts of experiences in OMD contexts and provides reflective commentary on them.

School-based problem-solving consultation is an indirect problem-solving process where the consultant works directly with the teacher in order to solve a current work problem of the teacher. The focus of school-based problem-solving consultation was to remediate a current difficult; however, during school-based problem-solving consultation, the teacher developed coping skills that improved his/her ability to handle future problems. Although the subject of several previous syntheses of the literature attesting to its promise, the current state of school-based problem consultation effectiveness was not known. This study sought to update the school-based problem-solving consultation effectiveness literature as measured by conducting a meta-analysis spanning the years 1986 to 2009. A secondary goal was to identify variables that functioned as moderators. Following procedures advocated by Lipsey and Wilson in 2001, 19 studies were identified producing 205 effect sizes. However, these effect sizes were not calculated independently. Instead, the effect sizes from each study were averaged in order to form a mean effect size per study. The mean effects were then averaged to form the omnibus mean effect size. The omnibus mean effect size from the 19 studies was g = 0.42, with a range of -0.01 to 1.52 demonstrating a medium-sized effect. This effect size was more modest in magnitude when compared to the previous school-based problem-solving consultation meta-analyses; however, the results indicated that school-based problem-solving consultation positively impacted client-level outcomes. With the exception of grade level, moderator analyses produced little information in terms of statistical differences between and among categories for “teacher type of class, consultant type, school type, referral source, referral reason, consultation model, comparison group, intervention type, design quality, outcome measured, and data type. For grade level, students in the “Other/Not Specified” category benefited most from school-based problem-solving consultation when compared to the “Elementary (K-6)” category. In addition to examining the omnibus mean effect size and potential moderators, limitations and implications for practice and future research were discussed.

This study investigated the effects of output stimulus tasks and glosses on L2 incidental vocabulary learning. Two meta-analytic studies were conducted. The first was intended to provide a systematic statistical synthesis of the effects of output stimulus tasks on L2 incidental vocabulary learning. A total of 12 studies were included in this meta-analysis. Results showed that language learners gained more benefit from using output stimulus tasks to learn vocabulary than those who only read a text. Results also supported the involvement load hypothesis that language learners who perform a task with a higher extent of involvement load gain more L2 vocabulary. As opposed to studies with the low level of design quality, studies with high and medium levels of design quality were more likely to detect statistically significant differences among groups with different output stimulus tasks. Moreover, results suggested that time on task had a positive impact on L2 vocabulary learning. Learners who read a combination of expository and narrative texts outperformed those who only read either an expository or a narrative text in the vocabulary posttest. Learners who read a text with text-target word ratios of less than or equal to 2 percent did not learn significantly more vocabulary than those who read a text with a ratio of 2 percent to 5 percent. The second meta-analysis study used meta-analytic techniques to explore the effects of L1 textual and image-based glosses on second language (L2) incidental vocabulary learning while reading. Results revealed that language learners who were provided with textual glosses gained more vocabulary than those who had no access to glosses. Results suggested that text-target word ratios played an important role in second language vocabulary learning. Language learners who read a passage with a text-target word ratio of ≤2 percent outperformed those who read a passage with a text-target word ratio between 2 percent and 5 percent. No statistically significant difference was found between the groups that were provided with multiple-choice and single glosses. Compared to paper-and-pencil environments, computer-assisted settings did not significantly enhance L2 vocabulary learning. Language learners who read narrative reading materials did not significantly outperform those who were exposed to expository texts with regard to incidental vocabulary learning. No significant difference in L2 vocabulary learning was observed between groups who were given L1 textual glosses and those who had access to L1 textual image-based glosses.
