The primary role of speed in determining Digit Symbol scores is well established. Among the important questions that remain to be resolved are: (1) whether speed accounts for all of the age-related decline in Digit Symbol scores, and (2) whether memory ability makes any significant contribution to Digit Symbol performance, especially after controlling for speed. We analyzed data from the WAIS-III/WMS-III standardization sample to resolve these issues. As expected, speed (Digit Symbol-Copy) correlated very strongly with Digit Symbol--Coding. Memory (Digit Symbol--Incidental Learning or WMS-III index scores) correlated more moderately with Digit Symbol-Coding. Even after controlling for variance in Coding explained by Copying, a statistically significant proportion of the residual variance was explicable in terms of memory functions. The contribution of memory to Digit Symbol--Coding, while relatively small, is real. In addition, a small portion of the age-associated decline in Coding scores cannot be accounted for by Copying scores.

Abstract The characteristics and trends of observed river discharge into the Hudson, James, and Ungava Bays (HJUBs) for the period 1964–2000 are investigated. Forty-two rivers with outlets into these bays contribute on average 714 km3 yr−1 [= 0.023 Sv (1 Sv ≡ 106 m3 s−1)] of freshwater to high-latitude oceans. For the system as a whole, discharge attains an annual peak of 4.2 km3 day−1 on average in mid-June, whereas the minimum of 0.68 km3 day−1 occurs on average during the last week of March. The Nelson River contributes as much as 34% of the daily discharge for the entire system during winter but diminishes in relative importance during spring and summer. Runoff rates per contributing area are highest (lowest) on the eastern (western) shores of the Hudson and James Bays. Linear trend analyses reveal decreasing discharge over the 37-yr period in 36 out of the 42 rivers. By 2000, the total annual freshwater discharge into HJUBs diminished by 96 km3 (−13%) from its value in 1964, equivalent to a reduction of 0.003 Sv. The annual peak discharge rate associated with snowmelt has advanced by 8 days between 1964 and 2000 and has diminished by 0.036 km3 day−1 in intensity. There is a direct correlation between the timing of peak spring discharge rates and the latitude of a river’s mouth; the spring freshet varies by 5 days for each degree of latitude. Continental snowmelt induces a seasonal pulse of freshwater from HJUBs that is tracked along its path into the Labrador Current. It is suggested that the annual upper-ocean salinity minimum observed on the inner Newfoundland Shelf can be explained by freshwater pulses composed of meltwater from three successive winter seasons in the river basins draining into HJUBs. A gradual salinization of the upper ocean during summer over the period 1966–94 on the inner Newfoundland Shelf is in accord with a decadal trend of a diminishing intensity in the continental meltwater pulses.

Children with type 1 diabetes are at risk for negative psychosocial and physiological outcomes, particularly as they enter adolescence. The purpose of this randomized trial (n = 82) was to determine the effects, mediators, and moderators of a coping skills training intervention (n = 53) for school-aged children compared to general diabetes education (n = 29). Both groups improved over time, reporting lower impact of diabetes, better coping with diabetes, better diabetes self-efficacy, fewer depressive symptoms, and less parental control. Treatment modality (pump vs. injections) moderated intervention efficacy on select outcomes. Findings suggest that group-based interventions may be beneficial for this age group.

The authors evaluated the relative contributions of speed, memory, and visual scanning to Digit Symbol score in a sample of young adults (N = 87). Speed (Symbol Copy) explained 35% of Digit Symbol variance; only half of this was attributable to graphomotor speed (Name Printing), implying a role for perceptual speed. Visual-scanning tests (e.g., Symbol Scan) explained (on average) 34% of Digit Symbol variance, much of which was independent of perceptual-motor speed, establishing an important role for visual-scanning efficiency in Digit Symbol performance. By contrast, memory tests (on average) explained only 4% to 5% of Digit Symbol variance: statistically significant but clearly subsidiary, although a visual memory composite correlated more strongly with Digit Symbol. The Digit Symbol incidental learning procedures did, however, correlate moderately with other memory measures, suggesting that they are valid memory screening devices.

Scholarly productivity is used to index faculty achievement, but normative data on publication rates among academic psychologists are scarce. This article presents the results of a study of 1,216 faculty members from 96 schools, ranging from elite research universities to minor undergraduate colleges. As expected, faculty members at research universities publish the most, followed by those at elite 4-year schools and other doctoral institutions. Institutional prestige has little effect on productivity, except that elite universities employ a greater proportion of truly eminent scholars than other schools do. The fact that many of these scholars are hired by elite schools after achieving eminence elsewhere suggests that financial prowess, rather than institutional climate, produces the latter effect. Academics at all of these types of schools tend to continue publishing throughout their careers; achieving tenure has little effect on their subsequent scholarship. Faculty members at master's universities and lesser 4-year schools publish less than others and tend to cease publication activity after about 10 years, presumably upon receiving tenure. Males tend to publish more than females during the initial push for tenure, but not thereafter; females, unlike males, tend to increase their publication rates as they mature professionally. A subset of highly productive males who are moving toward more prestigious types of schools accounts for much of the remaininggender difference. The number of predoctoral publications is a relatively weak predictor of postdoctoral scholarship.

Although roles have been proposed for both graphomotor speed and learning in the execution of Digit Symbol, few data have been available concerning performance across the adult lifespan on the Symbol Copy, paired associates, or free recall measures derived from Digit Symbol and recommended in the WAIS-R-NI. We report findings on 177 healthy older adults (ages 50-90), providing normative data by age group, education level, and gender. As previously reported, Digit Symbol scores decline steeply with age (r = -.64). Symbol Copy speed declines almost as steeply (r = -.58). Incidental learning, however, declines only modestly (r = -.26 on both measures). Symbol Copy is a far stronger correlate of Digit Symbol (r = .72) than are paired associates or free recall (r = .26 and r = .28, respectively). The 2 incidental learning measures do, however, offer valuable supplementary information as part of a comprehensive individual assessment. When low Digit Symbol scores are produced by slowing on Symbol Copy, further evaluation of perceptual and motor speed and dexterity are indicated. When low incidental learning scores are obtained, further evaluation of memory is warranted. Qualitative analysis of errors (e.g., rotations) made on the incidental learning procedures may also be valuable.

Increasing consumption of refined sugar has been implicated in many gastrointestinal disorders on epidemiological grounds. Nine volunteers agreed to participate in a study comparing the effects of a diet containing 165 g refined sugar/day with a diet of only 60 g/day on gut transit, bile acid metabolism, and fermentative activity of the intestinal flora. The wet and dry weight, pH, and water content of the stools were similar on the two diets. On the high sugar diet mouth-to-anus transit time was significantly prolonged, despite a shortened mouth-to-caecum transit time. The faecal concentration of total bile acids and the faecal concentration of secondary bile acids increased significantly. Diet affected neither the serum bile acid pattern nor the concentration. Breath hydrogen tests showed significantly enhanced H2 production on the high sugar diet. We conclude that the quantity of refined sugar in the diet can significantly influence gut function and the composition of bowel contents.

OBJECTIVE: Equinovarus foot deformity following stroke or traumatic brain injury compromises walking capacity, interfering with activities of daily living. In soft-tissue surgery the imbalanced muscles responsible for the deviant position of the ankle and foot are lengthened, released and/or transferred. However, knowledge about the effectiveness of surgical correction is limited. The aim of the present study was to carry out a systematic review of the literature to assess the effects of surgical correction of equinovarus foot deformity in patients with stroke or traumatic brain injury. METHODS: A systematic search of full-length articles in the English, German or Dutch languages published from 1965 to March 2011 was performed in PubMed, EMBASE, CINAHL, Cochrane and CIRRIE. The identified studies were analysed following the International Classification of Functioning, Disability and Health criteria. RESULTS: A total of 15 case series, case control and historically controlled studies (CEBM level 4) were identified, suggesting that surgical correction of equinovarus foot deformity is a safe procedure that is effective in terms of re-obtaining a balanced foot position, improving walking capacity and diminishing the need for orthotic use. DISCUSSION: Further validation of surgical correction of equinovarus foot deformity following stroke or traumatic brain injury is required, using higher level study designs with validated assessment tools. Comparing surgical techniques with other interventions is necessary to generate evidence upon which treatment algorithms could be based.

This study examined the relationship between intimate partner violence (IPV), internalized homophobia, and psychological maladjustment in a convenience sample of young adult women. Rates of psychological and physical abuse in women’s same-sex relationships were shown to be commensurate to previously reported rates of violence in the IPV literature; rates of sexual coercion were also ascertained. A relationship was found between Moral and Religious Attitudes Toward Lesbianism (MRATL), a dimension of internalized homophobia, and the perpetration of sexual coercion. As expected, internalized homophobia was connected to psychological maladjustment. In addition, both the perpetration of psychological aggression and physical violence were associated with emotional instability. The study findings are discussed within the current body of literature on IPV.

The unresolved difficulties associated with defining and measuring population density strictly circumscribe the scope and nature of the conclusions that can be properly derived from differentials in man:land ratios. Any conclusions about human density will have meaning only to the extent that they are based on a recognition that this density must be viewed in both static and dynamic terms and that it cannot be isolated in analysis, from either the social and cultural setting, the demographic characteristics of the population, or the broader processes of social change within the society. In and of itself, the familiar man:land ratio says more about area than it does about either the human experience of density or the relation of population to resources. This ratio is therefore essentially meaningless as an indicator of comparative conditions of life among different countries and different geographic regions. The mere fact of having a relatively low average population density thus, does not automatically entitle a nation to complacency about its ability to adjust readily to future population change, either in terms of growth in numbers or in the geographic location of its people.

When typing on a keyboard a user can be authenticated through what he/she types (username, password), but also through how he/she types, that is, through keystroke dynamics. We study whether authentication through keystroke dynamics is sufficiently reliable as a security instrument to be used together with the more standard instruments. Based on a data set of 1254 participants who typed the same username and password, 20 times each, we develop a test statistic and obtain the power of our test. We conclude that keystroke dynamics can be a reliable security instrument for authentication, if used together with other instruments. It seems more suitable for authentication (verification) than for identification. Dwell times (how long a key is held pressed) are more discriminatory and therefore more powerful than flight times (time between consecutive press times).

Block Design tasks are neuropsychologically valuable, but standard scoring sacrifices potentially useful information that could elucidate the cognitive processes underlying performance failures. Qualitative indices that were proposed in the WAIS-R-NI [Kaplan, E., Fein, D., Morris, R., & Delis, D. (1991). The WAIS-R as a neuropsychological instrument [Manual]. San Antonio, TX: Psychological Corporation] should help to remedy this situation but have received little research attention. We present WAIS-R Block Design data for 177 healthy older adults (aged 50-90) incorporating several qualitative measures, outlining normative ranges and examining age differences. Proportional scoring, counts of single-block placement and rotation errors, counts of parameter-violating errors such as breaking configuration, and availability of implicit grid information all offer potentially valuable supplementary data that can enrich clinical interpretation of Block Design protocols.

Decision‐makers in organizations often make what appear as being intuitively obviously and reasonable decisions, which often turn out to yield unintended outcomes. The cause of such ineffective decisions can be a combination of cognitive biases, poor mental models of complex systems, and errors in thinking provoked by anxiety, all of which tend to reinforce the currently held belief structures that reinforce even further resistance to change in people. While Senge has advocated for the use of simulations, called, “microworlds” to overcome such resistance, there are times when such simulations are not available for use or are otherwise infeasible. At these times, alternative methods need to be considered for improving the capacity of managers to learn from experience and improve the quality of their decision‐making. Among the alternatives that can be used to improve decision‐making are role‐play, neuro‐linguistic programming, the use of corrective methods related to groupthink, critical thinking skills and failure analysis. A review of the causes of poor decision‐making, methods of changing one's beliefs, guiding principles for making better decisions, and a process for improving the quality of lessons learned from experience is presented in this article.

We analyzed WAIS-III/WMS-III standardization data for evidence of the construct validity and clinical utility of the Digit Symbol-Incidental Learning procedures (Pairing and Free Recall). Scores on both tests correlated moderately with WMS-III memory index scores (mean r=.38 for Pairing and .36 for Free Recall). Cutoff scores can be used to identify younger and older adults likely to suffer from memory impairment. In the standardization sample (which excludes neurological patients), these have moderate positive predictive power (averaging .56 if either test yields a positive finding), moderate negative predictive power (.76), and high specificity (.88), but low sensitivity (.35). In a clinical sample, the same cutoff scores were much more sensitive, correctly identifying 88% of a group of patients with Alzheimer's Disease. Examinees who obtain these low scores should receive follow-up memory testing. Very high scores are associated with a reduced risk of memory impairment.

Image programs are a specific type of psychosocial cancer service developed to help women address the appearance‐related side effects of cancer treatment. They include the Look good, feel better program, medical and mastectomy boutiques and other cosmetic and makeover programs. In this paper I argue that the primary goal of image programs is to 'normalize' female cancer patients by hiding the physical evidence of illness and by reconstructing women with cancer as physically attractive, heterosexual and not disabled. The recovery of femininity and a feminine appearance is seen as central to recovering health. As a result, image programs take on a certain clinical legitimacy and become powerful reproducers of heterosexist and ableist discourses of gender and wellness.

Undergraduates (N = 68) completed inventories measuring innovation motivation (need to be different and innovation expectancy), psychoticism, extraversion, neuroticism, and symptomatic distress, as well as a sentence completion measure of adjustment. They also wrote lyric poems using an associative procedure and completed house–tree–person drawings. Poems were scored for originality and arousal potential and independently judged for quality by two college writing instructors. Drawings were scored for original features and independently judged for quality by two art therapists. The need to be different and current adjustment problems correlated significantly with both originality scores and judged creativity on both tasks, often interacting to explain much of the variance in creativity. Innovation expectancy and psychoticism displayed significant correlations with some creativity measures. Originality scoring and expert judgment correlated well on both tasks. Originality and judged creativity correlated significantly across creative domains, supporting a domain-general view of creativity.

Abstract According to social learning theory, innovation motivation is partly composed of the subjective value set upon the opportunity to engage in different behaviors. An inventory measuring this explicit need to be different ( v Differ) has not previously been evaluated for its ability to predict divergent production of ideas. In this study, the v Differ scale was administered together with three divergent production (originality) measures: a word‐association test, a new uses test, and a test requiring examinees to name members of categories. Responses were scored for unusualness in the sample. The need to be different predicted unusual category exemplars ( r = .31), word associations ( r = .30), and uses for common objects ( r = .31). Although general knowledge or verbal fluency also predicted some originality scores, innovation motivation tests accounted for significant variance over and above that attributable to these ability measures.

8-Nitro-2'-deoxyguanosine (8-nitrodG) is a relatively unstable, mutagenic lesion of DNA that is increasingly believed to be associated with tissue inflammation. Due to the lability of the glycosidic bond, 8-nitrodG cannot be incorporated into oligodeoxynucleotides (ODNs) by chemical DNA synthesis and thus very little is known about its physicochemical properties and base-pairing preferences. Here we describe the synthesis of 8-nitro-2'-O-methylguanosine, a ribonucleoside analogue of this lesion, which is sufficiently stable to be incorporated into ODNs. Physicochemical studies demonstrated that 8-nitro-2'-O-methylguanosine adopts a syn conformation about the glycosidic bond; thermal melting studies and molecular modelling suggest a relatively stable syn-8-nitroG·anti-G base pair. Interestingly, when this lesion analogue was placed in a primer-template system, extension of the primer by either avian myeloblastosis virus reverse transcriptase (AMV-RT) or human DNA polymerase β (pol β), was significantly impaired, but where incorporation opposite 8-nitroguanine did occur, pol β showed a 2:1 preference to insert dA over dC, while AMV-RT incorporated predominantly dC. The fact that no 8-nitroG·G base pairing is seen in the primer extension products suggests that the polymerases may discriminate against this pairing system on the basis of its poor geometric match to a Watson-Crick pair.

This book presents an ecocritical reading of DeLillo’s novels in an attempt to mediate between the seemingly incompatible influences of postmodernism and environmentalism. Martucci argues that although DeLillo is responding to and engaging with a postmodern culture of simulacra and simulation, his novels do not reflect a postmodernist theory of the "end of nature." Rather, his fiction emphasizes the lasting significance of the natural world and alerts us to the dangers of destroying it. In order to support this argument, Martucci examines DeLillo’s novels in the context of traditional American literary representations of the environment, especially through the lens of Leo Marx’s discussion of the conflict between technology and nature found in traditional American literature. She demonstrate that DeLillo’s fiction explores the way in which new technologies alter perceptions and mediate reality to a further extent than earlier technologies; however, she argues that he keeps the material world at the forefront of his novels, thereby illuminating the environmental implications of these technologies. Through close readings of Americana, The Names, White Noise, and Underworld, and discussions of postmodernist and ecocritical theories, this project engages with current criticism of DeLillo, postmodernist fiction, and environmental criticism.

The identification and longitudinal assessment of traumatic brain injury presents several challenges. Because these injuries can have subtle effects, efforts to find quantitative physiological measures that can be used to characterize traumatic brain injury are receiving increased attention. The results of this research must be considered with care. Six reasons for cautious assessment are outlined in this paper. None of the issues raised here are new. They are standard elements in the technical literature that describes the mathematical analysis of clinical data. The purpose of this paper is to draw attention to these issues because they need to be considered when clinicians evaluate the usefulness of this research. In some instances these points are demonstrated by simulation studies of diagnostic processes. We take as an additional objective the explicit presentation of the mathematical methods used to reach these conclusions. This material is in the appendices. The following points are made: (1) A statistically significant separation of a clinical population from a control population does not ensure a successful diagnostic procedure. (2) Adding more variables to a diagnostic discrimination can, in some instances, actually reduce classification accuracy. (3) A high sensitivity and specificity in a TBI versus control population classification does not ensure diagnostic successes when the method is applied in a more general neuropsychiatric population. (4) Evaluation of treatment effectiveness must recognize that high variability is a pronounced characteristic of an injured central nervous system and that results can be confounded by either disease progression or spontaneous recovery. A large pre-treatment versus post-treatment effect size does not, of itself, establish a successful treatment. (5) A procedure for discriminating between treatment responders and non-responders requires, minimally, a two phase investigation. This procedure must include a mechanism to discriminate between treatment responders, placebo responders, and spontaneous recovery. (6) A search for prodromes of neuropsychiatric disorders following traumatic brain injury can be implemented with these procedures.
