Objective:
Verbal fluency consists of semantic and phonemic fluency and is often used to detect verbal ability and executive control (Shao et al., 2014). While research has found general verbal fluency impairments in chronic alcohol use, few studies have examined semantic and phonemic fluency separately (Stavro et al., 2012; Stephan et al., 2017). This meta-analytical study examines the performance of abstinent alcohol-dependent individuals on semantic fluency (categories) and phonemic fluency (letters).
Participants and Methods:As part of a larger study, two researchers independently searched eight databases, extracted required data, and calculated effect sizes on neuropsychological data in alcohol dependent (AD) individuals. Inclusion criteria for articles were: (a) comparison of abstinent alcohol-dependent patients to healthy controls, (b) matched control group on age, education, or IQ, and (c) standardized neuropsychological testing. Exclusion criteria included: (a) diagnosis of Axis I disorders (other than alcohol dependence), (b) comorbidity with other disorders that impact neuropsychological functioning, or (c) not published or translated into English. A total of 31 articles (AD n=1,080 and HC n=1,090) was analyzed in this study.
Results:Semantic fluency evidenced a statistically significant and medium effect size estimate (g = 0.632, p < 0.001). The heterogeneity for semantic fluency was statistically significant (Q=152.468, df=20, p=0.000). Phonemic fluency evidenced a statistically significant and medium effect size estimate (g = 0.572, p < 0.001). The heterogeneity for phonemic fluency was also statistically significant (Q=236.697, df=24, p=0.000).
Conclusions:Deficits in semantic and phonemic fluency are both associated with alcohol dependence. Although some previous research has reported more frontal lobe impact of alcohol, which would be expected to impact phonemic more readily than semantic fluency, this is not evident in the current data. There are many possible reasons for this failure to observe this dissociation meta-analytically. Some potential reasons include the possibility that alcohol affects multiple regions of the brain, that both these measures are affected by alcohol but miss the subtlety associated with frontal damage, or the likelihood that when studies are aggregated in meta-analysis the heterogeneity results in a regression to the mean effect size. These and other reasons are not mutually exclusive and future research should attempt to examine these and other hypotheses.

Objective:
Chronic alcohol consumption has been associated with widespread cognitive deficits, including psychomotor speed. Researchers have found impairments in reaction speed, information processing, and fine-finger movement in alcoholics (Oscar-Berman et al., 2015). There have also been mixed findings on the impact of duration of alcohol use on neurocognitive functioning (Beatty et al., 2000; Oscar-Berman et al., 2004). This meta-analytical study examines: (a) the performance of abstinent alcohol-dependent individuals on psychomotor speed using the Trail Making TestA (TMT-A), and (b) the effect of duration of alcohol use on TMT-A.
Participants and Methods:As part of a larger study, two researchers independently searched eight databases, extracted required data, and calculated effect sizes on neuropsychological data in alcohol dependent (AD) individuals. Inclusion criteria for articles were: (a) comparison of abstinent alcohol-dependent patients to healthy controls, (b) matched control group on age, education, or IQ, and (c) standardized neuropsychological testing. Exclusion criteria included: (a) diagnosis of Axis I disorders (other than alcohol dependence), (b) comorbidity with other disorders that impact neuropsychological functioning, or (c) not published or translated into English. Twenty-seven articles (AD n= 840 and HC n = 881) were analyzed in this study.
Results:The TMT-A evidenced a statistically significant and medium effect size estimate (g = 0.624, p < 0.001). The heterogeneity of TMT-A was statistically significant (Q=61.935, df=26, p=0.000) and moderate (I2=58.021%). The meta-regression analysis between duration of alcohol use in days and TMT-A was not statistically significant (Q=0.012, df=1, p=0.913).
Conclusions:TMT-A detects psychomotor speed deficits associated with alcohol dependence. Duration of alcohol use did not affect TMT-A performance, suggesting that other factors may have moderated this relationship. Further research should analyze other factors that affect psychomotor performance in alcohol dependent individuals.

Objective:
Heart failure occurs when the heart is unable to support a flow of blood that meets the body’s needs, ultimately resulting in decreased oxygenation throughout the body— including the brain. Results of previous research suggest that individuals with heart failure exhibit both localized and diffuse neuropsychological deficits. The aims of this study are to meta-analytically examine a) the performance of participants with heart-failure and healthy controls on the Mini Mental State Examination (MMSE), a neuropsychological test of general cognition, and b) the role of depressive mood as a potential moderator of performance on the MMSE in these participants.
Participants and Methods:Two researchers independently searched eight databases for articles that examined the neuropsychological functioning of patients with heart failure.
Inclusion criteria identified studies that had a heart failure group with a comparable control group and reported on neuropsychological assessment for both groups. Studies were excluded if a heart failure group had any other type of major organ failure or if the comparison was between different classes of heart failure rather than between a heart failure group and healthy controls.
Results:A meta-analysis using a random-effects model revealed a statistically significant and large effect size estimate (g= 0.727, p <.001) CI [.331, 1.123]. The heterogeneity was found to be statistically significant and in the large range, I2 = 83.027%, tau2 = .155, p < .001. A meta-regression analyzing the relationship between depressive mood and MMSE effect size estimates was statistically significant, Q residual = 8.715, df = 3, p = .03.
Conclusions:This study is the first to examine the relationship between depressive mood and general cognitive status (as measured by the MMSE) in participants with heart failure. The strong relationship between cognitive status and heart failure, and the role of depression in explaining a statistically significant portion of the heterogeneity in the relationship seen in primary studies, highlights the importance of accurately assessing depression when studying the effect of heart failure on cognition. Further research needs to examine the impact of depression on quality of life in patients with heart failure as potentially mediated by difficulties in cognition.

The local electrode atom probe (LEAP) has become the primary instrument used for atom probe tomography measurements. Recent advances in detector and laser design, together with updated hit detection algorithms, have been incorporated into the latest LEAP 5000 instrument, but the implications of these changes on measurements, particularly the size and chemistry of small clusters and elemental segregations, have not been explored. In this study, we compare data sets from a variety of materials with small-scale chemical heterogeneity using both a LEAP 3000 instrument with 37% detector efficiency and a 532-nm green laser and a new LEAP 5000 instrument with a manufacturer estimated increase to 52% detector efficiency, and a 355-nm ultraviolet laser. In general, it was found that the number of atoms within small clusters or surface segregation increased in the LEAP 5000, as would be expected by the reported increase in detector efficiency from the LEAP 3000 architecture, but subtle differences in chemistry were observed which are attributed to changes in the way multiple hit detection is calculated using the LEAP 5000.

This paper examines two policy initiatives that research shows can increase opportunities for physical activity and, in turn, improve health outcomes. These initiatives — shared use and Safe Routes to School (SRTS) — can and should be embraced by schools to improve student and community health. Fear of liability, however, has made many schools reluctant to support these efforts despite their proven benefits. This paper addresses school administrators’ real and perceived liability concerns and identifies four strategies for managing the fear of liability and mitigating any potential liability exposure.

Chrysomela scripta Fabricius adults showed a feeding preference for the youngest, most succulent leaves of tissue-cultured Populus × euramericana. Larvae fed equally on all leaves with water contents greater than 73%. Larvae chose shoot bark for feeding after all leaves with water contents greater that 70% had been consumed. Larvae reared on immature foliage had shorter developmental times and higher prepupal weights than those reared on mature foliage.

In recent years, a great deal of interest has been directed toward the use of organic materials in the development of high-efficiency optoelectronic and photonic devices. There is a myriad of possibilities among organic materials, which allows flexibility in the design of unique structures with a variety of functional groups. The use of nonlinear optical (NLO) organic materials as thin-film waveguides allows full exploitation of their desirable qualities by permitting long interaction lengths and large susceptibilities allowing modest power input. There are several methods in use to prepare thin films such as Langmuir-Blodgett (LB) and self-assembly techniques,2-4 vapor deposition.5-7 growth from sheared solution or melt,8,9 and melt growth between glass plates.10 Organic-based materials have many features that make them desirable for use in optical devices, such as high second- and third-order nonlinearity, flexibility of molecular design, and damage resistance to optical radiation. However, processing difficulties for crystals and thin films has hindered their use in devices.
We discuss the potential role of microgravity processing of a few organic and polymeric materials. It is of interest to note how materials with second- and third-order NLO behavior may be improved in a diffusion-limited environment and ways in which convection may be detrimental to these materials. We focus our discussion on third-order materials for all-optical switching, and second-order materials for frequency conversion and electro-optics. The goal of minimizing optical loss obviously depends on processing methods. For solution-based processes, such as solution crystal growth and solution photopolymerization, it is well known that thermal- and solutal-density gradients can initiate buoyancy-driven convection. Resultant fluid flows can affect transport of material to and from growth interfaces and become manifest in the morphology and homogeneity of the growing film or crystal. Likewise, buoyancy-driven convection can hinder production of defect-free, high-quality crystals or films during crystal and film growth by vapor deposition.
