The WASI™ as a Screening Tool for Counselors in the Referral Decision for a Neuropsychological Evaluation

When a client has cognitive impairment resulting from cerebral dysfunction (CD) that goes undiagnosed and, therefore, untreated, psychotherapy and rehabilitation outcome is likely to be impacted negatively. Due primarily to managed care, screening for CD has reduced substantially. Master's level counselors need a cost-efficient way to detect possible CD and, thus, justify referral for neuropsychological evaluation. This study examined the Wechsler Abbreviated Scale of Intelligence™ (WASI™) instrument's ability to screen for possible CD by examining the relationship between a) WASI Performance IQ (PIQ) and Verbal IQ (VIQ) scores and neuropsychological test scores, and b) the VIQ-PIQ discrepancy and the severity of disability. In this retrospective study, test scores were extrapolated from neuropsychological assessments conducted between 2001 and 2004 on 73 CD-diagnosed adults at a CARF accredited rehabilitation facility. Disability severity ratings of mild, moderate, and severe were assigned based on clinical judgment and interrater agreement. The assessment battery included the WASI and several neuropsychological tests: Halstead-Reitan TPT, TMT-A and B, and FOT; WMS-III VR-I and 2, LM-1 and 2, and MC; McCarron-Dial HVDT; SDMT; and SCT. Based upon a multitrait-multimethod matrix, mild to moderate convergent and discriminant validity was found with the WASI VIQ and PIQ traits among neuropsychological verbal …

Wayfinding tools in public library buildings: A multiple case study.

Access: Use of this item is restricted to the UNT Community
Wayfinding is the process of using one or more tools to move from one location to another in order to accomplish a task or to achieve a goal. This qualitative study explores the process of wayfinding as it applies to locating information in a public library. A group of volunteers were asked to find a selection of items in three types of libraries-traditional, contemporary, and modern. The retrieval process was timed and the reactions of the volunteers were recorded, documented, and analyzed. The impact of various wayfinding tools-architecture, layout, color, signage, computer support, collection organization-on the retrieval process was also identified. The study revealed that many of the wayfinding tools currently available in libraries do not facilitate item retrieval. Inconsistencies, ambiguities, obstructions, disparities, and operational deficiencies all contributed to end-user frustration and retrieval failure. The study suggests that failing to address these issues may prompt library patrons-end users who are increasingly interested in finding information with minimal expenditures of time and effort-may turn to other information-retrieval strategies and abandon a system that they find confusing and frustrating.

Which version of the equity market timing affects capital structure, perceived mispricing or adverse selection? (open access)

Which version of the equity market timing affects capital structure, perceived mispricing or adverse selection?

Baker and Wurgler (2002) define a new theory of capital structure. In this theory capital structure evolves as the cumulative outcome of past attempts to time the equity market. Baker and Wurgler extend market timing theory to long-term capital structure, but their results do not clearly distinguish between the two versions of market timing: perceived mispricing and adverse selection. The main purpose of this dissertation is to empirically identify the relative importance of these two explanations. First, I retest Baker and Wurgler's theory by using insider trading as an alternative to market-to-book ratio to measure equity market timing. I also formally test the adverse selection model of the equity market timing: first by using post-issuance performance, and then by using three measures of adverse selection. The first two measures use estimates of adverse information costs based on the bid and ask prices, and the third measure is based on the close-to-offer returns. Based on received theory, a dynamic adverse selection model implies that higher adverse information costs lead to higher leverage. On the other hand, a naïve adverse selection model implies that negative inside information leads to lower leverage. The results are consistent with the equity market timing theory of …

Wild Practices: Teaching the Value of Wildness (open access)

Wild Practices: Teaching the Value of Wildness

The notion of wildness as a concept that is essentially intractable to definition has profound linguistic and ethical implications for wilderness preservation and environmental education. A survey of the ways in which wilderness value is expressed through language reveals much confusion and repression regarding our understanding of the autonomy of nature. By framing discussions of wilderness through fact-driven language games, the value of the wild autonomy in nature becomes ineffable. In removing wildness from the discourse on wilderness we convert wilderness value from an intrinsic value into a distorted instrumental value. If we want to teach others that wilderness value means something more than a recreational, scientific, or economic opportunity, we need to include other ways of articulating this value in our education programs. Through linking the wildness of natural systems with the wild forms in human language games, I examine the conceptual freedom required for valuing autonomy in nature. The focus on what is required of language in expressing the intrinsic value of wilderness reveals that wilderness preservation and environmental education need complementary approaches to the current science-based frameworks, such as those used by the National Park Service. The disciplines of poetry, literature, ethics, and aesthetics offer alternative language …

Within-session session changes in responding as a function of habituation vs. satiation. (open access)

Within-session session changes in responding as a function of habituation vs. satiation.

Behavior analysts refer to a decrease in response rate following repeated, contingent presentations of a reinforcing stimulus as a product of satiation. Other evidence suggests that these decreases may often be due to habituation to the sensory properties of the reinforcing stimulus. The investigation reported here sought to determine whether decreases in operant responding by 3 adults with developmental disabilities were due to satiation or habituation. During baseline, participants placed poker chips into a container, and no reinforcement was available. Within subsequent phases, participants received diet lemon-lime soda on a fixed-ratio (FR) schedule of reinforcement. In one condition, the color of the soda was constant throughout the session, and in another condition food coloring was added several minutes into the session. Results for at least 2 participants indicated that: (a) soda functioned as a reinforcer for placing poker chips in the can; (b) response rates decreased within the session to baseline levels; and (c) response rates increased following a change in the color of the soda within the session. Results for the third participant were less clear. The results support the argument made by other researchers that the terms habituation (a weakening of a behavior following contact with the reinforcing …

Work and Family Conflict: Expectations and Planning Among Female College Students (open access)

Work and Family Conflict: Expectations and Planning Among Female College Students

Young women today are anticipating involvement in both career and family. The competing demands of family and work often result in work-family conflict. A survey was administered to 124 female college students exploring the importance they place on work and family roles, the expectations they have for combining these roles, and their attitudes toward planning for multiple roles. Identity theory provides a foundation for understanding the choices women make regarding their anticipated participation in work and family roles. The results suggest that although college women are expecting to have demanding careers and involved family lives, they are not planning realistically in order to facilitate the combining of career and family roles with a minimum of conflict.

Working Memory Processes in the Encoding of Intentions (open access)

Working Memory Processes in the Encoding of Intentions

The primary interest of this investigation concerned working memory functioning and cue/act discrimination during encoding of intentions. The study included manipulations of working memory and intention load to investigate the encoding processes related to prospective memory (PM). Three experiments are presented that involve working memory distraction tasks at the time of encoding the PM intentions, as well as varying numbers of cues and actions. In the first experiment three cues were paired with one action, in the second, one cue with three actions, and in the third, three cues with three actions. Results suggest that the central executive is involved in binding a cue to an action, and that this operation is key to PM success. Furthermore, the phonological loop seems primarily involved with processing of cues and the visuospatial sketchpad with actions. It is further proposed that the processes of the phonological loop and visuospatial sketchpad must be successful before the central executive can bind the cues and acts together, which is possibly the most important part in the encoding of intentions. By directly examining PM at the time of encoding, information was gained that allows for a more complete understanding of the nature of how we form and …
