Watershed - A Transdisciplinary Social Design Process Applied To An Environmental Issue, Forrest Thomas Conroy

Graduate Theses, Dissertations, and Problem Reports (ETD)

Wicked problems are often vast, complex, and difficult to navigate. Often used in dealing with social design issues, the term "wicked" is intended to connote a problem that is difficult to define and solve rather than its moral implications.1 These problems, like watershed maintenance and pollution mitigation, involve an entwined community of diverse players, intricate systems, and ever-changing terrain. Because of their pluralistic nature, these problems can seem impossible to solve and even impossible to understand. This requires a collective approach and new ways of thinking to create better understanding and solutions. Important changes occur when citizens are knowledgeable, see …


Evolutionary Search Techniques With Strong Heuristics For Multi-Objective Feature Selection In Software Product Lines, Abdel Salam Sayyad Aug 2014

Evolutionary Search Techniques With Strong Heuristics For Multi-Objective Feature Selection In Software Product Lines, Abdel Salam Sayyad

Graduate Theses, Dissertations, and Problem Reports (ETD)

Software design is a process of trading off competing objectives. If the user objective space is rich, then we should use optimizers that can fully exploit that richness. For example, this study configures software product lines (expressed as feature models) using various search-based software engineering methods. Our main result is that as we increase the number of optimization objectives, the methods in widespread use (e.g. NSGA-II, SPEA2) perform much worse than IBEA (Indicator-Based Evolutionary Algorithm). IBEA works best since it makes most use of user preference knowledge. Hence it does better on the standard measures (hypervolume and spread) but it …

Data from 626 women without a history of breast cancer were used to investigate associations between psychosocial variables (e.g., anxiety, body dissatisfaction, cancer fatalism; religious beliefs and participation) and breast awareness behaviors (BSE frequency and proficiency, frequency of checking for lumps, …


Supervisee Experiences Of Impression Management, The Supervisory Working Alliance, And Counseling Self-Efficacy, Jennifer M. Haist Aug 2014

Supervisee Experiences Of Impression Management, The Supervisory Working Alliance, And Counseling Self-Efficacy, Jennifer M. Haist

Graduate Theses, Dissertations, and Problem Reports (ETD)

Supervision plays a vital role in fostering competent, ethical and effective counseling psychologists. However, studies have shown that supervisees act in ways that counteract the benefits of supervision. Trainees manage supervisor impressions to the detriment of their professional growth; they withhold information that would help supervisors promote learning, clarify misunderstandings, gain insight into supervisee weaknesses and strengths, and provide feedback that would enhance supervisee competence. Supervisee nondisclosure is a particularly prevalent impression management behavior documented in the supervision literature (Hill, Thompson, & Corbett, 1992; Ladany et al., 1996). It and other forms of impression management may be particularly related to …
