Hispanic English Learners' Responses to Longitudinal English Instructional Intervention and the Effect of Gender: A Multilevel Analysis

This longitudinal study investigated 196 Hispanic English learners' responses to an English instructional intervention from kindergarten to second grade. The effect of student gender was also examined as a secondary focus. The intervention consisted of ongoing professional development and structured and systematic English intervention during an English as a second language (ESL) block. A multilevel modeling approach revealed that (a) the intervention effect was positive and significant, reflecting a range of phonological awareness, oral language skills, and decoding and reading proficiency, indicating the effectiveness of this intervention, and (b) that boys possessed more expressive vocabulary knowledge upon school entry and acquired receptive vocabulary faster than girls, while both girls and boys attained comparable levels of decoding skills and reading proficiency. We conclude that the effect of instructional intervention is stronger than the effect of gender. More well-planned, scientifically based research is needed to promote the linguistic development of English learners.
Predictors of Communication Satisfaction During Performance Appraisal Interviews

The following study investigates the relationship between employee perceptions of communication behaviors and satisfaction with communication that occurred during a recent performance appraisal interview. In association with communication satisfaction the relationship between communication training and the amount of time elapsed between the appraisal interview and participation in this survey were also investigated. Results indicate that perceptions of understanding and the quality of communication are significant predictors of satisfaction with communication during the appraisal interview. Implications for training in the use of communication skills to improve communication during the performance appraisal interview are discussed.
On Motivated Role Selection: Gender Beliefs, Distant Goals, and Career Interest

Despite widespread changes in occupational opportunities, men and women continue to show divergent preferences for careers. This research invoked a motivational framework to explain sex-differentiated career interest. From a role congruity perspective (Diekman & Eagly, 2008), the internalization of gender roles leads people to endorse gender-stereotypic goals, which then lead to interest in occupations that afford the pursuit of those goals. Three studies provided evidence for the hypotheses. Study 1 found that male-and female-stereotypic careers were perceived to afford different goals. Studies 2 and 3 found that men and women endorsed different goals and that this gender-normative goal endorsement predicted gender-stereotypic career interest. In addition, structural equation modeling (Study 3) indicated that internalization of gender roles fully accounted for sex-differentiated goal endorsement. These findings thus extend the social role theory framework to consider processes related to self-selection into specific social roles.
Rotation Curve Measurement using Cross‐Correlation

Long‐slit spectroscopy is entering an era of increased spatial and spectral resolution and increased sample size. Improved instruments reveal complex velocity structure that cannot be described with a one‐dimensional rotation curve, yet samples are too numerous to examine each galaxy in detail. Therefore, one goal of rotation curve measurement techniques is to flag cases in which the kinematic structure of the galaxy is more complex than a single‐valued curve. We examine cross‐correlation as a technique that is easily automated and works for low signal‐to‐noise spectra. We show that the technique yields well‐defined errors which increase when the simple spectral model (template) is a poor match to the data, flagging those cases for later inspection. We compare the technique to the more traditional, parametric technique of simultaneous emission‐line fitting. When the line profile at a single slit position is non‐Gaussian, the techniques disagree. For our model spectra with two well‐separated velocity components, assigned velocities from the two techniques differ by up to ∼52% of the velocity separation of the model components. However, careful use of the error statistics for either technique allows one to flag these non‐Gaussian spectra.
Mediated Intergroup Contact: Concept Explication, Synthesis, and Application

This article had an overarching goal of paving a foundation for the scholarship on intergroup contact in the field of media research. This goal was approached from three different directions: concept explication, synthesis, and application. First, selective reviews of literature on intergroup contact research and media effects research were conducted to identify a term that can best represent existing terminology on intergroup contact via media consumption and elaborate on its definition. A synthesis of intergroup contact literature and existing studies of mediated intergroup contact revealed potential moderators and mediators of mediated contact effect. Last, current practices of media production and consumption in the United States were analyzed through the lens of intergroup contact to provide an assessment of the current state of mediated contact. Based on these reviews and syntheses, suggestions for future research and practice were made.
Altered White Matter Integrity in Smokers Is Associated with Smoking Cessation Outcomes

Smoking is a significant cause of preventable mortality worldwide. Understanding the neural mechanisms of nicotine addiction and smoking cessation may provide effective targets for developing treatment strategies. In the present study, we explored whether smokers have white matter alterations and whether these alterations are related to cessation outcomes and smoking behaviors. Sixty-six smokers and thirty-seven healthy non-smokers were enrolled. The participants underwent magnetic resonance imaging scans and smoking-related behavioral assessments. After a 12-week treatment with varenicline, 28 smokers succeeded in quitting smoking and 38 failed. Diffusion parameter maps were compared among the non-smokers, future quitters, and relapsers to identify white matter differences. We found that the future relapsers had significantly lower fractional anisotropy (FA) in the orbitofrontal area than non-smokers, and higher FA in the cerebellum than non-smokers and future quitters. The future quitters had significantly lower FA in the postcentral gyrus compared to non-smokers and future relapsers. Compared to non-smokers, pooled smokers had lower FA in bilateral orbitofrontal gyrus and left superior frontal gyrus. In addition, regression analysis showed that the left orbitofrontal FA was correlated with smoking-relevant behaviors. These results suggest that white matter alterations in smokers may contribute to the formation of aberrant brain circuits underlying smoking behaviors and are associated with future smoking cessation outcomes.
Mobile phone use among female entertainment workers in Cambodia: an observation study.

BACKGROUND Text or voice messages containing health behavior change content may be an inexpensive, discreet, sustainable and scalable way to reach populations at high risk for HIV. In Cambodia, one of the important high-risk populations is female entertainment workers (FEWs). This ethnographic study aims to explore typical phone use, examining patterns and behaviors that may influence the design of future mHealth interventions. METHODS The study consisted of one 8-hour non-participant observation session for 15 randomly sampled FEWs. Observations focused on capturing normal daily use of mobile devices. Observation checklists were populated by observers during the observations and a post-observation survey was conducted. Findings were discussed with Cambodian HIV outreach workers and HIV research fellows and their interpretations are summarized below. RESULTS In this ethnographic study, all 15 participants made calls, checked the time and received research-related texts. More than half (n=8) of the participants engaged in texting to a non-research recipient. About half (n=7) went on Facebook (FB) and some (n=5) listened to music and looked at their FB newsfeed. Fewer played a mobile game, posted a photo to FB, went on YouTube, used FB chat/messenger, watched a video on FB, played a game on FB, used FB call/voice chat, looked at their phone's background or used the LINE app. Fewer still shared their phones, left them unattended, added airtime or changed their SIM cards. When participants received a research text message, most did not share the text message with anyone, did not ask for help deciphering the message and did not receive help composing a response. Notable themes from observer notes, HIV outreach workers and researchers include reasons why phone calls were the most frequent mode of communication, examples of how cell phone company text messages are used as a form of behavior change, literacy as a persistent barrier for some FEWs, and FEWs' high interest in receiving health-related messages and less concern about privacy and phone-sharing issues than expected. CONCLUSIONS This study suggests texting is a part of normal phone use although not as frequently used as voice calls or Facebook. Despite the less frequent use, FEWs were able to send and receive messages, were interested in health messages and were not overly concerned about privacy issues. Texting and voice messaging may be useful tools for health behavior change within the FEW population in Cambodia.
Surgical adjuvant therapy of large-bowel carcinoma: an evaluation of levamisole and the combination of levamisole and fluorouracil. The North Central Cancer Treatment Group and the Mayo Clinic.

A total of 401 eligible patients with resected stages B and C colorectal carcinoma were randomly assigned to no-further therapy or to adjuvant treatment with either levamisole alone, 150 mg/d for 3 days every 2 weeks for 1 year, or levamisole plus fluorouracil (5-FU), 450 mg/m2/d intravenously (IV) for 5 days and beginning at 28 days, 450 mg/m2 weekly for 1 year. Levamisole plus 5-FU, and to a lesser extent levamisole alone, reduced cancer recurrence in comparison with no adjuvant therapy. These differences, after correction for imbalances in prognostic variables, were only suggestive for levamisole alone (P = .05) but quite significant for levamisole plus 5-FU (P = .003). Whereas both treatment regimens were associated with overall improvements in survival, these improvements reached borderline significance only for stage C patients treated with levamisole plus 5-FU (P = .03). Therapy was clinically tolerable with either regimen and severe toxicity was uncommon. These promising results have led to a large national intergroup confirmatory trial currently in progress.
Spin–Orbit Alignment of the TrES-4 Transiting Planetary System and Possible Additional Radial-Velocity Variation

We report new radial velocities of the TrES-4 transiting planetary system, including observations of a full planetary transit, with the High Dispersion Spectrograph on the Subaru 8.2 m telescope. Modeling of the Rossiter– McLaughlin effect indicates that the exoplanet TrES-4b has a sky-projected angle of � = 6:
Accountability and Performance in Charter Schools in Florida: A Theory-Based Evaluation

This paper utilizes the framework of program theory evaluation to assess the operation of charter schools in Florida in the 1999-2000 school year. Charter school theory is modeled and a series of hypotheses are developed about the linkages expected to produce the primary program outcomes, improved student academic performance and change in the operations of regular public schools. The hypotheses are evaluated with quantitative and qualitative data. The analysis raises questions about the theory. Student performance in charter schools is not better than in regular public schools and, as might be expected, regular schools have not changed their behavior in response to their challenge. The outcome is attributed primarily to shortcomings in establishing accountability for the actions of charter schools.
Parental smoking patterns and their association with wheezing in children

OBJECTIVE: To investigate parental smoking patterns and their association with wheezing in children. METHODS: We performed a case-control study that included 105 children between 6 and 23 months of age who were divided into two groups: cases (children with 3 previous episodes of wheezing) and controls (healthy children without wheezing). The children's exposure to cigarette smoking was estimated using a questionnaire completed by the mothers and by the children's urinary cotinine levels. RESULTS: Based on both the questionnaire results and cotinine levels, exposure to cigarette smoking was higher in the households of cases in which the incidence of maternal smoking was significantly higher than that of paternal smoking. Children in this group were more affected by maternal smoking and by the total number of cigarettes smoked inside the house. Additionally, the questionnaire results indicated that the risk of wheezing was dose dependent. The presence of allergic components, such as atopic dermatitis and siblings with allergic rhinitis and asthma, greatly increased the odds ratio when wheezing was associated with cotinine levels. CONCLUSION: Children exposed to tobacco smoke have an increased risk of developing wheezing syndrome. This risk increases in association with the number of cigarettes smoked inside the house and the presence of other allergic components in the family.
Performance Evaluation of the Positron Scanner ECAT EXACT

The Cologne Special is a prototype of the ECAT EXACT (model 921), a new generation of Siemens-CTI PET scanners. It consists of three rings of 48 BGO block detectors each, covering an axial field of view of 16.2 cm with a patient port of 56.2 cm diameter. This results in a total of 24 rings with 384 crystals each, giving 47 contiguous image planes in two-dimensional (2D) mode. Total system sensitivity is 216 kcps/μCi/ml for a 20 cm cylinder phantom in 2D. This increases to 1.5 Mcps/μCi/ml in 3D. Data are acquired in the stationary mode only (no wobble motion), resulting in a transaxial spatial resolution of better than 6 mm full width at half-maximum (FWHM) at the center, which degrades to 7.5 mm tangentially and 9.6 mm radially at a radius of 20 cm. Average axial resolution changes from 5.0 mm FWHM at the center to 8.1 mm at R = 20 cm. Count rate performance was investigated at different low energy discriminator settings and found to be linear up to 2.5 μCi/ml with a 20 cm phantom. The magnitude and distribution of scatter were evaluated for both septa-extended and septa-retracted conditions for a range of energy thresholds. Brain, heart, and whole-body studies with the new tomography demonstrate the versatility of its applications without compromising on physical performance.
MAL facilitates the incorporation of exocytic uroplakin-delivering vesicles into the apical membrane of urothelial umbrella cells

MAL, suggested to play a key role in the apical sorting of membrane proteins, is not involved in the apical sorting of uroplakins. Instead, it plays an important role in facilitating the incorporation of the uroplakin-delivering exocytic vesicles into the apical surface of terminally differentiated urothelial umbrella cells.

“Well, that’s why I asked the question sir”: Well as a discourse marker in court

ABSTRACT This article discusses the use of well as a discourse marker in some New Zealand courtrooms. While well has been discussed by many in the past, the data have been selected mainly from small, friendly encounters of various kinds, including sociolinguistic interviews. The study reported on here looks at a very different situation that necessarily involves a range of relationships and includes both cooperative and adversarial activities. It confirms that explanations of well’s use focusing on single strands such as social indicators (e.g. gender) or discourse coherence are simplistic, a more fruitful account being afforded through a multi-pronged functional approach. Finally, the article considers the application of politeness and relevance theory. *
[Ultrasonography of the inferior vena cava (IVC) in the diagnosis and monitoring of therapy in patients with chronic congestive heart failure].

OBJECTIVE This prospective clinical study investigated whether the relatively simple and cost-effective ultrasonography of the inferior vena cava (IVC) represents a valid clinical tool to assess the effectiveness of diuretic therapy in patients with chronic congestive heart failure (CHF). METHODS Measurement of the resting and inspiratory diameter of the VCI repeatedly during diuretic therapy in 23 consecutive patients (11 women, 70 +/- 10 years) with CHF and comparing the results to the daily measured body weight and serum creatinine in these patients. Results were compared with the IVC diameter obtained in 33 healthy controls (16 women, 42 +/- 15 years). In addition, the IVC collapse index was calculated to assess inspiratory movements of the IVC in patients on day 1 and 10 of therapy. RESULTS The IVC diameter at rest was 2.4 +/- 0.6 cm and decreased to 2.0 +/- 0.7 cm at inspiration, which was significantly greater than in healthy controls (1.4 +/- 0.4 cm at rest and 1.05 +/- 0.5 cm at inspiration; p = 0.008 and p = 0.01, respectively). The IVC diameter decreased continuously and significantly (p < 0.003) from day 1 to day 10 during diuretic therapy without a concomitant rise in serum creatinine. At beginning of therapy, the collapse-index of the IVC was significantly greater in patients than in controls. However, after 10 days of therapy this index reached similar values to those observed in controls. CONCLUSION Ultrasonographic measurements of IVC diameter and inspiratory movements are a quantifiable and reliable approach to assess the hypervolemia associated with CHF. Normalization of inspiratory IVC collapse movement correlates with successful diuretic therapy and can be reliably used for bedside assessment and monitoring treatment in CHF patients.
Ripple joins for online aggregation

We present a new family of join algorithms, called ripple joins, for online processing of multi-table aggregation queries in a relational database management system (DBMS). Such queries arise naturally in interactive exploratory decision-support applications. Traditional offline join algorithms are designed to minimize the time to completion of the query. In contrast, ripple joins are designed to minimize the time until an acceptably precise estimate of the query result is available, as measured by the length of a confidence interval. Ripple joins are adaptive, adjusting their behavior during processing in accordance with the statistical properties of the data. Ripple joins also permit the user to dynamically trade off the two key performance factors of on-line aggregation: the time between successive updates of the running aggregate, and the amount by which the confidence-interval length decreases at each update. We show how ripple joins can be implemented in an existing DBMS using iterators, and we give an overview of the methods used to compute confidence intervals and to adaptively optimize the ripple join “aspect-ratio” parameters. In experiments with an initial implementation of our algorithms in the POSTGRES DBMS, the time required to produce reasonably precise online estimates was up to two orders of magnitude smaller than the time required for the best offline join algorithms to produce exact answers.
[The association between cognitive deficits and different outcomes of schizophrenia].

AIM Schizophrenia is a disorder with different outcomes. Besides the positive and negative symptoms, cognitive impairment is an important core feature of schizophrenia and often pre-dates the disorder. Cognition has consistently been related to outcome in schizophrenia. Given this finding and the fact that diagnosing and treating schizophrenia as early as possible has better outcome chances, the current study investigated the hypothesis that cognitive performance is associated with two seemingly opposite outcomes: clinical remission and forced hospitalization three years after first assessment. METHODS Subjects in the current study were schizophrenia patients not in an active psychosis during cognitive testing (N = 321). The results of the cognitive tests were used as predictor variables for the status of remission or the occurrence of a forced hospitalization in the three years following the cognitive testing. The cognitive tests included were WAIS-III subtests (Digit symbol, Information, Arithmetic, Block Design), Benton Facial Recognition task, Hinting task and the Rey Auditory Verbal Learning task. Besides these cognitive predictors, several relevant covariates (gender, age, education, number of psychotic episodes, duration of illness and amphetamine, cannabis or cocaine intoxication) were analyzed. Two multinomial logistic regression and analyses were conducted with the cognitive tests as independent variables and remission and forced hospitalization as dependent variables in separate models. RESULTS The results showed that better performance on the verbal tasks (WAIS-III arithmetic score (b=0.17) and the WAIS-III information score (b=0.22)) and less psychotic episodes (b=-0.64) was associated with remission status. Worse performance on the memory task (b=-0.20) and more psychotic episodes (b=0,85) was related to forced hospitalization. CONCLUSIONS This three-year longitudinal study showed that higher verbal IQ is a protective factor and poor memory and higher number of psychotic episodes are risk factors of the outcome of schizophrenia. This suggests that future research on prediction tools for the outcome of schizophrenia should include assessment of verbal IQ and verbal memory.
