Accessibility of alcohol expectancies from memory: impact of mood and motives in college student drinkers.

OBJECTIVE It has been hypothesized that alcohol outcome expectancies (AOEs) exist within an associative memory network and that their accessibility is facilitated in the presence of alcohol-related cues. The purpose of the present study was to examine whether the accessibility of specific AOEs varies as a function of mood state and gender and to determine whether this relationship is moderated by affect-related drinking motives. METHOD Undergraduate students (N = 302) were randomly assigned to one of three conditions (i.e., positive, negative and neutral mood). Mood states were achieved using musical mood-induction procedures. Postmood-induction AOEs, obtained using self-generation, were classified into five expectancy categories: social/ situational enhancement (SSE), positive emotional functioning (PEF), relaxation/tension reduction (RTR), physical/pharmacological effects (PPE) and miscellaneous (MISC). RESULTS Logistic regression analyses revealed that SSE and RTR expectancies were differentially accessible across mood conditions. SSE expectancies were most highly accessible to participants in a positive mood, and RTR expectancies were most highly accessible to participants in a relatively neutral mood. Although drinking motives did not moderate the AOE-mood relationship, they emerged as significant predictors of SSE and RTR expectancies. The accessibility of specific AOEs differed among men and women. CONCLUSIONS The findings suggest that mood serves as an implicit prime for the accessibility of specific AOEs. The implications of these findings for research concerning memory-based, cognitive-affective expectancy networks are discussed.
Design of a Computerised Flight Mill Device to Measure the Flight Potential of Different Insects

Several insect species pose a serious threat to different plant species, sometimes becoming a pest that produces significant damage to the landscape, biodiversity, and/or the economy. This is the case of Rhynchophorus ferrugineus Olivier (Coleoptera: Dryophthoridae), Semanotus laurasii Lucas (Coleoptera: Cerambycidae), and Monochamus galloprovincialis Olivier (Coleoptera: Cerambycidae), which have become serious threats to ornamental and productive trees all over the world such as palm trees, cypresses, and pines. Knowledge about their flight potential is very important for designing and applying measures targeted to reduce the negative effects from these pests. Studying the flight capability and behaviour of some insects is difficult due to their small size and the large area wherein they can fly, so we wondered how we could obtain information about their flight capabilities in a controlled environment. The answer came with the design of flight mills. Relevant data about the flight potential of these insects may be recorded and analysed by means of a flight mill. Once an insect is attached to the flight mill, it is able to fly in a circular direction without hitting walls or objects. By adding sensors to the flight mill, it is possible to record the number of revolutions and flight time. This paper presents a full description of a computer monitored flight mill. The description covers both the mechanical and the electronic parts in detail. The mill was designed to easily adapt to the anatomy of different insects and was successfully tested with individuals from three species R. ferrugineus, S. laurasii, and M. galloprovincialis.
Pairwise Maximum Entropy Models for Studying Large Biological Systems: When They Can Work and When They Can't

One of the most critical problems we face in the study of biological systems is building accurate statistical descriptions of them. This problem has been particularly challenging because biological systems typically contain large numbers of interacting elements, which precludes the use of standard brute force approaches. Recently, though, several groups have reported that there may be an alternate strategy. The reports show that reliable statistical models can be built without knowledge of all the interactions in a system; instead, pairwise interactions can suffice. These findings, however, are based on the analysis of small subsystems. Here, we ask whether the observations will generalize to systems of realistic size, that is, whether pairwise models will provide reliable descriptions of true biological systems. Our results show that, in most cases, they will not. The reason is that there is a crossover in the predictive power of pairwise models: If the size of the subsystem is below the crossover point, then the results have no predictive power for large systems. If the size is above the crossover point, then the results may have predictive power. This work thus provides a general framework for determining the extent to which pairwise models can be used to predict the behavior of large biological systems. Applied to neural data, the size of most systems studied so far is below the crossover point.
Shifting Conversations on Girls' and Women's Self-Injury: An Analysis of the Clinical Literature in Historical Context

Through a historical review of girls' and women's episodic and repetitive self-injury -scholarship focusing primarily on white, middle-class women in North America and Britain - in the clinical literature from 1913 to the present, the author identifies four shifts over time. These are: 1) varying degrees of clinical interest in and numbers of publications on self-injury, 2) changing conceptualizations of self-injury, 3) changing treatment approaches for self-injury, and 4) changing characterizations of women who self-injure. Moving from research studies which indicate that self-injury typically presents in females during adolescence, this article elucidates how self-injury may reflect girls' developmental struggles within a patriarchal culture and embody a narrative of women's experiences of violation. Bringing together the history of self-injury and a feminist, relational analysis, it is argued that the historical discourse on self-injury mimics women's experiences of objectification and violence by silencing and distorting their self-injury.
Re-evaluating the role of television criticism in the British press

While television criticism is very popular with readers of newspapers, it has attracted little academic interest, whether as a form of journalistic practice or as part of a critical-public discourse on television. One of the most influential articles on television criticism was published by Mike Poole in 1984, in which he lambasted much of the existing television criticism for approaching television from within a literary-based paradigm, one which he thought was unsuitable for such a medium. Since this article was published, apart from a few articles and chapters, there has been little further attempt to analyse television criticism in the British press in any depth. In this article I argue that, at a time of dramatic changes occurring in the newspapers and television industries, there is a need to develop a better understanding of the form and role of television criticism.
Morphology of the supercluster–void network in ΛCDM cosmology

We report here the first systematic study of the supercluster-void network in theCDM concordance cosmology in which voids and superclusters are treated on an equal footing. We study the dark matter density field in real space smoothed on a scale of 5 h −1 Mpc. Superclusters are defined as individual members of an overdense excursion set, and voids are defined as individual members of a complementary underdense excursion set at the same density threshold. We determine the geometric, topological and morphological properties of the cosmic web at a large set of density levels by computing Minkowski functionals for every supercluster and void using SURFGEN (described recently by Sheth et al.). The properties of the largest (percolating) supercluster and the complementary void are found to be very different from those of the individual superclusters and voids. In total, the individual superclusters occupy no more than about 5 per cent of the volume and contain no more than 20 per cent of the mass if the largest supercluster is excluded. Likewise, in total, individual voids occupy no more than 14 per cent of the volume and contain no more than 4 per cent of the mass if the largest void is excluded. Although superclusters are more massive and voids are more voluminous, the difference in maximum volumes is no greater than an order of magnitude. The genus value of individual superclusters can be ∼5, while the genus of individual voids can reach ∼50, implying a significant amount of substructure in superclusters and especially in voids. One of our main results is that large voids, as defined through the dark matter density field in real space, are distinctly non-spherical.

Employee Justice Across Cultures

This article explores the moderating influence of Hofstede’s cultural dimensions (individualism/collectivism, masculinity/femininity, uncertainty avoidance, and power distance) on the relationship between justice perceptions and both supervisor- and employer-related outcomes. The integration of justice theories with Hofstede’s national culture typology implies multiple, and potentially competing, propositions regarding the impact of culture on justice effects. To sort out these issues, the authors present meta-analytic findings summarizing data from 495 unique samples, representing over 190,000 employees working in 32 distinct countries and regions. Results indicate that justice effects are strongest among nations associated with individualism, femininity, uncertainty avoidance, and low power distance. The authors discuss these findings in terms of the practice of justice across cultures.
The Cortical Dynamics of Intelligible Speech

An important and unresolved question is how the human brain processes speech for meaning after initial analyses in early auditory cortical regions. A variety of left-hemispheric areas have been identified that clearly support semantic processing, although a systematic analysis of directed interactions among these areas is lacking. We applied dynamic causal modeling of functional magnetic resonance imaging responses and Bayesian model selection to investigate, for the first time, experimentally induced changes in coupling among three key multimodal regions that were activated by intelligible speech: the posterior and anterior superior temporal sulcus (pSTS and aSTS, respectively) and pars orbitalis (POrb) of the inferior frontal gyrus. We tested 216 different dynamic causal models and found that the best model was a “forward” system that was driven by auditory inputs into the pSTS, with forward connections from the pSTS to both the aSTS and the POrb that increased considerably in strength (by 76 and 150%, respectively) when subjects listened to intelligible speech. Task-related, directional effects can now be incorporated into models of speech comprehension.
Effect of Constructivist-Based Teaching Strategy on Academic Performance of Students in Integrated Science at the Junior Secondary School Level.

Integrated science plays vital role in Nigerian science education programme because it prepares pupils at the Junior Secondary School level for the study of core science subjects at the Senior Secondary School level which in turn brings about students’ interest in science oriented courses at the tertiary institutions. Despite government’s efforts to encourage science teaching and learning among Nigerian students right from the Junior Secondary School level, the enrolment of students in core science subjects and science oriented courses at the Senior Secondary School level and tertiary institutions level respectively, is not encouraging. This is as a result of Junior Secondary School students’ negative attitude towards integrated science. Research reports indicate that this negative attitude was caused, majorly, by teachers’ conventional (lecture) method of teaching integrated science. Research reports on the effectiveness of constructivist-based teaching strategy revealed that the strategy enhanced students’ academic performance. In view of this, this study examines the effectiveness of constructivist-based teaching strategy on academic performance in integrated science by Junior Secondary School students in South-West Nigeria. Quasi-experimental research design was used to achieve the purpose of this study. Participants were 120 Junior Secondary School Students randomly selected from four out of the 25 co-educational Junior Secondary Schools in Ijebu-ode local government area of ogun state, South-west Nigeria. Findings revealed that the constructivist instructed students had higher scores on the post test and the delayed post test, compared to those exposed to conventional (lecture) method of teaching. We concluded that if integrated science teachers could incorporate constructivist-based teaching strategy into their teaching methods, there would be an improvement in academic performance of Junior Secondary School Students in integrated science. The researchers recommended that integrated science teachers should incorporate constructivist-based teaching strategy in their methods of teaching. Key words: Nigeria, constructivism, conventional (lecture), integrated science, academic performance, junior secondary school III students.
Color and women hitchhikers' attractiveness: Gentlemen drivers prefer red

Research has shown that with some nonhuman primates, red is associated with greater sexual attractiveness of females. Five female confederates in their early 20s posed as hitchhikers wearing T-shirts of different colors (black, white, red, blue, green, or yellow). It was found that the women wearing red solicited a higher response in the number of male drivers who stopped to offer a ride. No color effect was found when considering the behavior of female drivers. © 2010 Wiley Periodicals, Inc. Col Res Appl, 2012
Social Engagement and Customer Profitability in Online Customer Networks

The rapid growth of the Internet has led to a revolution in the relationship between customers and companies. After the first experiences on social media platforms, companies started hosting their own online customer networks where formerly passive consuming customers are able to connect, share, and cooperate with each other and the company. This social engagement of customers is generally considered as an incredible value for the hosting company. However, while previous research regularly takes a positive relationship between users’ social engagement and customer profitability in online customer networks for granted, there is still a lack of research rigorously analyzing this aspect in detail. Against this background, the aim of our paper is to provide an in-depth investigation of the relationship between users’ social engagement and customer profitability in online customer networks using a unique dataset of a German direct banking institution. This leads to interesting results that do not support either existing statements in literature or best current practices. Indeed, in our case we do not generally observe significant higher social engagement for “buyers” compared with “nonbuyers”.
Oxidizing enzymes and vitamin C in tomatoes.

samples we avoided the bruised part, and our two samples gave results of 27-4 and 29-5 mg. /100 g. Two further samples taken from parts in contact with the bruise, but not including it, gave results of 11-3 and 14-5. In our opinion these results indicate the possibility of a rapid loss of vitamin C in bruised tomatoes by the penetration of the oxidase into the juice. The tomato appeared perfectly normal apart from the bruise.
Review of inverse probability weighting for dealing with missing data

The simplest approach to dealing with missing data is to restrict the analysis to complete cases, i.e. individuals with no missing values. This can induce bias, however. Inverse probability weighting (IPW) is a commonly used method to correct this bias. It is also used to adjust for unequal sampling fractions in sample surveys. This article is a review of the use of IPW in epidemiological research. We describe how the bias in the complete-case analysis arises and how IPW can remove it. IPW is compared with multiple imputation (MI) and we explain why, despite MI generally being more efficient, IPW may sometimes be preferred. We discuss the choice of missingness model and methods such as weight truncation, weight stabilisation and augmented IPW. The use of IPW is illustrated on data from the 1958 British Birth Cohort.
The Efficacy of Text Messaging to Improve Social Connectedness and Team Attitude in Student Technical Communication Projects

This experimental study investigates the impact of short-messaging service (SMS)—text messaging—on social connectedness and group attitude in student technical communication projects. It also investigates message types and communication medium preferences. Using a between-subjects design, the experiment compares two student groups: SMS only and non-SMS. The results indicated several statistically significant differences. Compared to students in the non-SMS group, students in the SMS-only group (a) communicated more, (b) felt more connected, and (c) sent more questions, answers, and nonproject-related messages. These results provide empirical evidence for using SMS in team contexts.
A prospective study of surgical margin status in oral squamous cell carcinoma: A preliminary report

A protocol was created for prospective margin status evaluation of patients with Oral SCC. Margins are evaluated intra‐ and post‐operatively during three stages. Patients were divided into three groups: group 1 in which one margins were sampled randomly, group 2 with frozen sections taken from the surgical bed and 3 in which they were taken from the tumor specimen itself. Patients in group 3 showed the best correlation with final margin status and survival. J. Surg. Oncol. 2008;98:572–578. © 2008 Wiley‐Liss, Inc.
Speech, language and communication for individuals with Down syndrome — An overview

Children with Down syndrome are usually good communicators. They are keen to interact socially right from infancy but they have to rely on non-verbal skills such as gesture for longer than other children because they usually experience significant speech and language delay. Once they start to talk, they make good use of the speech and language skills that they have for the same range of communicative activities as everyone else, particularly if encouraged to do so by sensitive support from those around them at home, at school and in the community. However, they have specific difficulty with learning grammar and with developing clear speech. Some of the reasons for their difficulties with learning to talk are known and provide pointers to effective intervention strategies. Researchers and practitioners worldwide now agree on the principles for effective intervention. Since speech and language skills are central to the development of mental abilities such as thinking, reasoning and remembering as well as to social inclusion, it is essential that speech and language is a focus for parents, teachers and therapists from infancy through to adult life. This overview covers development from birth to teenage years, and to understand the speech and language needs of primary and secondary age children, teachers and parents are encouraged to read the whole overview as the children's difficulties have their roots in the preschool years.
On the polynomial solvability of distributionally robust k-sum optimization

In this paper, we define a distributionally robust k-sum optimization problem as the problem of finding a solution that minimizes the worst-case expected sum of up to the k largest costs of the elements in the solution. The costs are random with a joint probability distribution that is not completely specified but rather assumed to be known to lie in a set of probability distributions. For k=1, this reduces to a distributionally robust bottleneck optimization problem while for k=n, this reduces to distributionally robust minimum sum optimization problem. Our main result is that for a Fréchet class of discrete marginal distributions with finite support, the distributionally robust k-sum combinatorial optimization problem is solvable in polynomial time if the deterministic minimum sum problem is solvable in polynomial time. This extends the result of Punnen and Aneja [On k-sum optimization, Oper. Res. Lett. 18(5)(1996), pp. 233–236] from the deterministic to the robust case. We show that this choice of the set of distributions helps preserve the submodularity of the k-sum objective function which is an useful structural property for optimization problems.
Language specific bootstraps for UG categories

This paper argues that the universal categories N/V are not applied to content words before the grammatical markings for reference D(eterminers) and predication I(nflection) have been acquired (van Kampen, 1997, contra Pinker, 1984). Child grammar starts as proto-grammar with language-specific operators and category-neutral content words Xo. The first content words are used as proper names with topic-intention and as brand names with characterizing-intention. The language-specificity of early operators may be illustrated by the use of wh-pronouns (what/where? ) in English versus the use of illocution particles (nou/denn? ) in Dutch/German child language. Subsequently, deictic operators for topic are regularized as Do and deictic operators for comment as Io. These functional categories are the bootstraps for category assignment and , as a subdivision of the lexicon. The generalized conclusion is that language-specific systems are not acquired due to a common UG entrance. They rather are highly frequent language-specific bootstraps that coax the child into an adult system that eventually fits UG principles. The operators in proto-grammar are situation-related, whereas the functional categories Io/D o are highly sensitive to syntactic context. This explains why, in a bilingual situation, a language switch in the context-free operators will be relatively easy. A language switch in functional categories, by contrast, will have a reflex on the syntactic context and be less easy.
Regulation of the ald Gene Encoding Alanine Dehydrogenase by AldR in Mycobacterium smegmatis

ABSTRACT The regulatory gene aldR was identified 95 bp upstream of the ald gene encoding l-alanine dehydrogenase in Mycobacterium smegmatis. The AldR protein shows sequence similarity to the regulatory proteins of the Lrp/AsnC family. Using an aldR deletion mutant, we demonstrated that AldR serves as both activator and repressor for the regulation of ald gene expression, depending on the presence or absence of l-alanine. The purified AldR protein exists as a homodimer in the absence of l-alanine, while it adopts the quaternary structure of a homohexamer in the presence of l-alanine. The binding affinity of AldR for the ald control region was shown to be increased significantly by l-alanine. Two AldR binding sites (O1 and O2) with the consensus sequence GA-N2-ATC-N2-TC and one putative AldR binding site with the sequence GA-N2-GTT-N2-TC were identified upstream of the ald gene. Alanine and cysteine were demonstrated to be the effector molecules directly involved in the induction of ald expression. The cellular level of l-alanine was shown to be increased in M. smegmatis cells grown under hypoxic conditions, and the hypoxic induction of ald expression appears to be mediated by AldR, which senses the intracellular level of alanine.
