A Solution to the Mental Health Problem?

Discusses other solutions to the mental health problem other than increasing the number of psychologists, psychiatrists, and social workers. At the author's state supported adult outpatient clinic, they have modified the operation of their clinic to make an approach to this problem by utilizing a resource group of those who are already in a position to foster the psychological health of others, such as ministers, physicians, and teachers. The authors discuss the implementation of this philosophy. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Metacognition in prospective memory: Are performance predictions accurate?

This study investigated the role of metacognition in event-based prospective memory. The aim of the study was to explore the relation between an item-level prediction (judgments of learning, JOL) and actual performance. The task and JOLs allowed a differentiation of the two components of prospective memory tasks (retrospective vs. prospective). Results revealed that individuals' predictions were (moderately) accurate for delayed JOLs but not for JOLs that had to be given immediately after task encoding. Moreover, data revealed an underconfidence-with-practice effect only for the retrospective component. For the prospective component, a substantial and general level of underconfidence in individuals' prediction–performance ratios was observed. The importance of metacognitive factors for prospective memory is discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Mental disorders are brain disorders: You think?

Recent years have seen an explosion of biologically based studies, interventions, and explanations for most mental disorders. Indeed, the mantra that mental disorders are brain disorders is frequently stated and certainly is at least partially true. Yet, the current landslide of information, produced with new extraordinary technologies, has resulted in limited clarity. The area of mental disorders remains laden with deficient, contradictory, and unproven explanations and treatments. One common rationale for this state is the failure to translate new scientific findings into practise. A more defensible and encompassing explanation focuses on the very basic conceptualizations and definitions of these disorders. Patently powerful methodologies can be no better or worse than the clarity of the problems under study. Numerous examples of definitional and diagnostic problems exist that have led to the lack of clarity and application of research findings. Alternative research strategies are discussed with a focus on the high-risk paradigm. A series of studies of a single characteristic of individuals at risk for problems with alcohol is presented.

Discrimination in the 21st century: Are science and the law aligned?

Although scholars agree that traditional forms of discrimination have generally been supplanted by subtler interpersonal manifestations of discrimination, it is yet unknown whether targets of these behaviors or the American judicial branch recognize such negative behaviors as violations of extant law. Extending research and theory, we propose that denigrating messages toward women and ethnic minorities (i.e., microaggressions) emerge in workplace interactions and are sometimes interpreted as discrimination. Specifically, this research explores the presence, severity, and frequency of microaggressions that appear in a random sample of race and gender discrimination cases in federal court dockets since the year 2000. The results suggest that microinsults, microinvalidations, and microassaults are reported in a variety of discrimination claims. However, only overt and intentional forms of microaggressions (microassaults) increased the likelihood that decisions favored plaintiffs. Thus, there may be a disconnect between forms of discrimination perceived by claimants and how those forms are evaluated by the legal system that protects victims of discrimination. This potential misalignment of science and practice is discussed, as are directions for future research. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Are there still indications for cerclage in 1995?

AIM: In order to assess their undertook a retrospective study in their department over a 4 year period: from January 1991 to December 1994. METHOD: the study concerned 129 patients who were treated by cerclage. This procedure was performed prophylactically in the great majority of them (97), while it was carried out as an emergency in 32 (25%). RESULTS: the authors drew a distinction between two groups (prophylactic and emergency suture) when analyzing the various results: complications due to suture, mean age of pregnancy at delivery, threatened premature labor, mean length of prolongation obtained. These personal data formed the basis of a review of the literature, in order to specify the indications for suture adopted by various authors at the present time. CONCLUSION: the authors found themselves to be in agreement with data from the literature, considering a history of at least two obstetric accidents (late abortions) and/or the existence of a severe uterine malformation to be the principal indication for prophylactic suture. "Emergency" suture should be performed whenever there is a serious threat of early premature labor in the presence of cervical changes such that suture offers the only chance of prolonging the pregnancy.     

Resistance to IT Change in the AEC Industry: Are the Stereotypes True?

Information technology (IT) change is difficult to implement successfully. Cultural (people) issues are a major barrier to IT implementation in the architecture, engineering, and construction (AEC) industry and existing change models have limitations, particularly with respect to cultural issues, which directly affect the ability of companies within the AEC industry to successfully implement IT change. This paper discusses research exploring the relationships between a resistance to change index (RTCI) and the demographics of individuals to understand different AEC participants’ resistance to IT change. Identifying individuals that exhibit different intensities of resistance to IT change efforts and their attendant demographics provides benchmark data to organizations. The ability to identify potential resistors is the first step in helping ensure that new technology implementations succeed. Data was collected from a 156-person sample of the AEC population to determine the relationships among different demographic groups within the AEC population and differences in their RTCI. The data analysis found several demographic groups that were different in their likelihood of resistance, including profession, gender, computer understanding and experience, and awareness of past or future changes occurring in their company. Age and education level were expected to have relationships with RTCI, based on industry stereotypes. The data analysis found that these stereotypes have no scientific basis. Two other stereotypes, gender and computer understanding and experience, were supported by the data analysis.     

Are associative changes in acquisition and extinction negatively accelerated?

Performance to a conditioned stimulus typically shows a negatively accelerated change with Pavlovian conditioning or extinction. This is commonly attributed to negatively accelerated changes in the underlying associative learning. However, the absence of well-specified rules for mapping learning into performance makes it difficult to infer changes in the size of associative changes for stimuli occupying different points on the performance scale. This problem can be addressed by comparing responding to stimulus compounds, each consisting of 2 stimuli, 1 of which is poorly conditioned and 1 of which is well conditioned, when either the former or the latter receives a specified amount of additional training. This permits comparison at a common performance level. Two magazine-approach experiments in rats and 2 autoshaping experiments in pigeons used this technique to assess the form of the associative changes in acquisition and extinction.

Are Arabic and verbal numbers processed in different ways?

Four experiments were conducted in order to examine effects of notation--Arabic and verbal numbers--on relevant and irrelevant numerical processing. In Experiment 1, notation interacted with the numerical distance effect, and irrelevant physical size affected numerical processing (i.e., size congruity effect) for both notations but to a lesser degree for verbal numbers. In contrast, size congruity had no effect when verbal numbers were the irrelevant dimension. In Experiments 2 and 3, different parameters that could possibly affect the results, such as discriminability and variability (Experiment 2) and the block design (Experiment 3), were controlled. The results replicated the effects obtained in Experiment 1. In Experiment 4, in which physical size was made more difficult to process, size congruity for irrelevant verbal numbers was observed. The present results imply that notation affects numerical processing and that Arabic and verbal numbers are represented separately, and thus it is suggested that current models of numerical processing should have separate comparison mechanisms for verbal and Arabic numbers.

Are Deicing Salts Necessary to Promote Scaling in Concrete?

The main purpose of the present study is to investigate the role of the material parameters such as permeability, thermal diffusivity, and pore size distribution on the mechanical behavior of cementitious structures submitted to frost action, such as surface scaling. An experimental device, in which a cement paste specimen is exposed to freezing-thawing cycles under a thermal gradient, has been developed. The experimental results show that under high thermal gradient (up to 1.5°C/mm), skin damage can occur without a saline layer in contact with the frozen surface. This can be explained and quantified in the framework of poromechanics. The model is based on the coupling between liquid-ice crystal thermodynamic equilibrium, liquid water transport, thermal conduction, and elastic properties of the different phases that form the saturated porous material. It eventually predicts that a less permeable sample is more susceptible to damage by surface defacement, which explains the observed experimental result.     

Deceptive packaging: Are the deceivers being deceived?

To investigate the effects of deceptive packaging, sample packages of potato chips containing various amounts were distributed to consumers who purchased a regular pack of the same brand. The only difference between the sample and the purchased pack was in terms of quantity of chips with the sample packs having various deficits. Preference data were obtained via a follow-up interview. The analyses of the questionnaire data indicated that: (a) consumers did not perceive weight differences between packs, (b) all indices of consumer preference favored the free pack when the two were of equal weight, and (c) all indices showed a marked decrease in preference for the experimental pack as the contents of the experimental packs were decreased.

Are zero tolerance policies effective in the schools?: An evidentiary review and recommendations.

Although there can be no dispute that schools must do all that can be done to ensure the safety of learning environments, controversy has arisen about the use of zero tolerance policies and procedures to achieve those aims. In response to that controversy, and to assess the extent to which current practice benefits students and schools, the American Psychological Association convened a task force to evaluate the evidence and to make appropriate recommendations regarding zero tolerance policies and practices. An extensive review of the literature found that, despite a 20-year history of implementation, there are surprisingly few data that could directly test the assumptions of a zero tolerance approach to school discipline, and the data that are available tend to contradict those assumptions. Moreover, zero tolerance policies may negatively affect the relationship of education with juvenile justice and appear to conflict to some degree with current best knowledge concerning adolescent development. To address the needs of schools for discipline that can maintain school safety while maximizing student opportunity to learn, the report offers recommendations for both reforming zero tolerance where its implementation is necessary and for alternative practice to replace zero tolerance where a more appropriate approach is indicated.

Are working memory deficits in bipolar disorder markers for psychosis?

Working memory deficits have been identified in bipolar disorder, but there is evidence suggesting that these deficits may be markers for psychosis rather than affective disorder. The current study examined this issue by comparing two groups of individuals with bipolar disorder, one with psychotic features and one without psychotic features, with a group of normal controls. Working memory was conceptualized as a multicomponent system that includes auditory and visuospatial short-term stores, executive control processes, and an episodic buffer that allows for communication between short- and long-term memory stores (Baddeley & Logie, 1999). Results indicated that only executive control processes significantly differentiated the psychotic and nonpsychotic bipolar groups, although visuospatial working memory differentiated both bipolar groups from controls. The results support the idea that some aspects of working memory performance are markers for psychosis, while others may be more general markers for bipolar disorders.

Are there "autistic-like" features in congenitally blind children?

Reduced levels of serum albumin concentration, a routine blood test, within the "normal" range have been reported to be associated with mortality risk. The literature is reviewed, with a focus on cohort studies meeting specified criteria, and findings are summarized. In studies of many populations, comprising healthy subjects and patients with acute or chronic illness, serum albumin concentration is inversely related to mortality risk in a graded manner over its entire range; the estimated increase in the odds of death ranges from 24% to 56% for each 2.5 g/l decrement in serum albumin concentration. The association predicts overall and cause-specific mortality including cardiovascular mortality. It is likely that albumin concentration is a highly sensitive indicator of preclinical disease and disease severity. A direct protective effect of the albumin molecule is suggested by the persistence of the association after adjustment for other known risk factors and preexisting illness, and after exclusion of early mortality. Although biologically plausible, there is no direct evidence for this hypothesis. Serum albumin concentration is an independent predictor of mortality risk and could be useful in the quantification of risk in a broad range of clinical and research settings.     

Proper-name processing: Are proper names pure referencing expressions?

Theoretical models of proper-name processing have been primarily derived from studies of people's names; however, they are thought to generalize to all classes of proper name. Five experiments are reported that use repetition priming to compare different classes of proper names. It was found that for people's names and landmark names, (a) production of a name in response to seeing a picture primed a subsequent familiarity decision to the same item's written name and (b) similarity, making a familiarity decision to an auditory presentation of a name primed a familiarity decision to the same item's written name. No comparable facilitation was found for the country-name stimuli. The presence of this specific facilitation was attributed to the nature of connectivity between conceptual and lexical representations. Theoretical views that proper names are unique, meaningless labels and that they are pure referencing expressions are evaluated. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
