Proficiency descriptors based on a scale-anchoring study of the new TOEFL iBT reading test

Providing information to test takers and test score users about the abilities of test takers at different score levels has been a persistent problem in educational and psychological measurement (Carroll, 1993). Since the 1990s Educational Testing Service has been investigating solutions to this problem through the development of proficiency scaling procedures and questiondifficulty research. In 1997 a proficiency scale was developed for the Test of English as a Foreign Language (TOEFL) Reading Comprehension section using a tree-based regression approach. The current study describes a scale-anchoring study of the new TOEFL iBT reading test and the resulting proficiency descriptors that are now part of the TOEFL iBT score report. The goal was to provide descriptive information about the abilities that test takers need in order to answer questions correctly. These abilities are those articulated in the new TOEFL Reading Framework and in the guidelines for writing test questions. Scale anchoring is a method of creating descriptors of the performance of test takers that is based on both empirical data and judgments by test developers. It has been used with a variety of assessments, including the National Assessment of Educational Progress (NAEP) and the Trends in International Mathematics and Science Study (TIMSS).
A Correlational Study of the Impact of Discrimination on Disposition During Hospital Emergency Services Contacts

Abstract Racial discrimination is a phenomenon that is reported to occur throughout many domains of service provision in health care and mental health care, and is a major research concern of the National Institute of Health. Many service delivery venues have received attention to address the potential presence of racial discrimination, although a form of mental health service delivery in hospital emergency rooms known as emergency services has received sparse attention. The current study is an investigation into the presence of racial discrimination and the potential impact of such discrimination in a rural Southeastern three county public mental health system. Methodological considerations of the research approach are also discussed.
Putting Young Children in Front of the Television: Antecedents and Outcomes of Parents’ Use of Television as a Babysitter

This study investigates predictors and consequences associated with the use of television as a babysitter for young children. Survey data of 844 children between the ages of six months and six years are analyzed using structural equation modeling. Parents’ attitude toward television emerged as best predictor of using television as a babysitter, which in turn predicted increased time spent watching television. Children of parents with strong positive attitudes toward television and, unexpectedly, children of parents with more education are at greater risk for increased television viewing if they are left in front of the television as a way of occupying them.
An Observer-Based de-Quantisation of Deutsch's Algorithm

Deutsch’s problem is the simplest and most frequently examined example of computational problem used to demonstrate the superiority of quantum computing over classical computing. Deutsch’s quantum algorithm has been claimed to be faster than any classical ones solving the same problem, only to be discovered later that this was not the case. Various de-quantised solutions for Deutsch’s quantum algorithm—classical solutions which are as efficient as the quantum one—have been proposed in the literature. These solutions are based on the possibility of classically simulating “superpositions”, a key ingredient of quantum algorithms, in particular, Deutsch’s algorithm. The de-quantisation proposed in this note is based on a classical simulation of the quantum measurement achieved with a model of observed system. As in some previous de-quantisations of Deutsch’s quantum algorithm, the resulting de-quantised algorithm is deterministic. Finally, we classify observers (as finite state automata) that can solve the problem in terms of their “observational power”.
A Comparison of Special, General and Support Teachers’ Controllability and Stability Attributions for Children’s Difficulties in Learning

The study aimed to explore teachers’ attributions for learner difficulties in their schoolwork. In order to explore their attributions of controllability and stability, three groups of teachers, general mainstream class teachers (N = 39), mainstream learning support teachers (N = 35), and special school teachers (N = 25) were asked to rate vignettes about children’s difficulties. The results showed that the two groups of teachers working in the mainstream settings viewed learners with identified support needs as having less control over their performance than those with no specific support needs, while special school teachers viewed both learner groups similarly. Similar findings were found for teacher attributions of controllability in high‐ and low‐ability learners. Stability attributions across all conditions showed that special school teachers viewed children’s difficulties as more amenable to change than did the two groups of mainstream teachers. The implications of these findings for inclusion in mainstream schools are discussed.
‘Crazyghettosmart’: a case study in Latina identities

Drawing from recent scholarship that examines schooling and the shifting terrain of youth identities, this study examines the identity constructions of Jessica, a Latina high school student. Our portrait of Jessica is part of a larger longitudinal study in which the middle and high school experiences of three Latinas, including Jessica, were examined. For this paper, we used data gathered from Jessica’s four years in high school, which included interviews from Jessica and her mother, and field observations from shadowing Jessica’s school days during her junior and senior years. Data analysis illustrated two broad themes: Jessica’s relationships with her academics and her social life, including the recent positioning of herself as a mother during her pregnancy in her senior year. Findings suggest that Jessica improvised her positions within various realms of school to both resist and reconfigure discourses that shaped her identities as a student and adolescent. This study argues for more research that examines and explores what youth have to say about their school experiences in order to illustrate the complex ways in which adolescents author themselves in school.
Mud for the Land

Besides the conventional financial and technical requirements, the typical property leasing agreement often includes the provision that a tenant be assured of the “quiet enjoyment of the land. ” The term quiet, apparently, refers not to protection from excess noise but an assurance that the tenant can enjoy his or her possession without interference and interruption, free from disturbance and dissension.1 But quiet also has a more active sense in the language of law, as settlements of ambiguous or disputed property relations speak of “quieting title. ” It’s a rather archaic phrase but an evocative and suggestive one for my purposes. What it tells us is that property doesn’t just happen. Just as quiet can be a verb, so property is an enactment (Rose 1994; Seed 1995). In this sense, a property regime is never complete and self-evident but requires a continual doing. The doing of real property happens not only in courtrooms and the law schools. Property must also be put to work on material spaces and real people, including owners and those who are to be excluded from that which is owned. In this grounding
Disabled People: Active or passive citizens - reflections from the Malaysian experience

The concept of citizenship has once again entered centre-stage in the debate among political philosophers, welfare theorists and activists. Marginalised groups, including disabled people around the world, are making a claim for their inclusion, rights and equal opportunities on the basis of citizenship rights. The Malaysian experience of disabled people within a newly-industrialising country draws lessons on how a disadvantaged section of Malaysian society struggle to enhance their rights as citizens of the nation and a share of the nations wealth. While there are difficult challenges, there are also positive indicators for the active citizenship participation of disabled people among fellow Malaysians.
Anti-smoking advertising campaigns targeting youth: case studies from USA and Canada

OBJECTIVE To assist in planning anti-smoking advertising that targets youth. Using five US state campaigns, one US research study, and a Canadian initiative as exemplars, an attempt is made to explain why certain advertising campaigns have been more cost effective than others in terms of reducing adolescent smoking prevalence. Several factors which prior research and theory suggest may be important to cost effectiveness are examined. Specifically, three variables pertaining to the advertising message (content, consistency, and clarity) and two variables related to the advertising execution or style (age of spokesperson and depiction of smoking behaviour) are studied. DESIGN A case study approach has been combined with supplemental data collection and analysis. To assess campaign effects, published articles and surveys of adolescent smoking prevalence in campaign versus control (non-campaign) locations were utilised. Adolescent subjects provided supplemental data on the advertising message variables. Trained adults content analysed each advertisement to assess the executional variables. SUBJECTS A total of 1128 seventh grade (age 12–13 years) and 10th grade (age 15–16 years) students participated in the supplemental data collection effort. RESULTS An anti-smoking advertising campaign initiated by Vermont researchers was found to be the most cost effective in that it significantly reduced adolescent smoking prevalence at a low per capita cost. Next in order of cost effectiveness were California, Massachusetts, and Florida because behavioural outcomes were inconsistent across time and/or grades. California was ranked higher than the other two because it spent less per capita. Minnesota and Canada were ineffective at reducing adolescent smoking prevalence, and no comparison outcome data were available for Arizona. Four factors were found to be associated with increased cost effectiveness: (1) a greater use of message content that prior research suggests is efficacious with youth; (2) a more concentrated use of a single efficacious message; (3) an avoidance of unclear messages; and (4) an increased use of youthful spokespeople that adolescents could more readily identify with. No indication was found that depictions of smoking undermined campaign effectiveness by inadvertently implying that smoking was prevalent. CONCLUSIONS The highly cost effective Vermont campaign can be used as a model for future efforts. It is estimated that 79% of the Vermont advertisements conveyed efficacious messages, 58% concentrated on a single efficacious message, 70% showed youthful spokespeople, and only 4% contained unclear messages. The results suggest that, in the less effective campaigns, as few as 25% of the advertisements contained messages that prior research indicates should be efficacious with youth, as few as 10% of the advertisements focused on one efficacious message, and up to 32% of the advertisements lacked clearcut messages.
Fertilization with acrosome-reacted mouse sperm: Implications for the site of exocytosis

For successful mammalian fertilization, sperm penetrate the outer investments of female gametes in the ampulla of the oviduct and fuse with the egg plasma membrane. The “fertilizing” sperm traverse the cumulus mass surrounding ovulated eggs, bind temporarily, and then penetrate through the zona pellucida, a structured extracellular glycomatrix, to enter into the perivitelline space (Fig. 1A). Underlying the anterior plasma membrane of the mouse sperm head is the acrosome, a Golgi-derived subcellular organelle. Sperm that approach ovulated eggs in the female reproductive tract have an intact acrosome. Before fertilization, the outer acrosomal membrane fuses with the sperm plasma membrane resulting in exocytosis of acrosomal contents (Fig. 1B). Only acrosome-reacted sperm are observed in the perivitelline space between the egg plasma membrane and the inner aspect of the zona pellucida and only acrosome-reacted sperm fuse with the egg. Thus, at some point during sperm penetration through the investments of ovulated eggs, acrosome exocytosis must occur. But where (Fig. 1A)? This is the issue that concerns Inoue et al. (1) in their study in PNAS.
Gaps between breastfeeding awareness and practices in Vietnamese mothers result from inadequate support in health facilities and social norms.

BACKGROUND Although gaps between breastfeeding awareness and practices have been described, determinants of the gaps have not been well investigated. OBJECTIVE The aim of this study was to examine determinants of the gap between breastfeeding awareness and practices in Vietnam. METHODS We interviewed 10,834 mothers with children aged 0-23 mo in 11 of 63 Vietnam provinces about breastfeeding practices, awareness, barriers, and support. A gap between awareness and practice was defined when a mother was aware of the benefit but did not perform the corresponding practice. Logistic regression models were used to examine determinants associated with the gaps. RESULTS The percentages of mothers with an awareness-practice gap for early initiation of breastfeeding, exclusive breastfeeding (EBF), continued breastfeeding at 1 y, and continued breastfeeding at 2 y were 34%, 66%, 19%, and 49%, respectively. Mothers had a lower awareness-practice gap in early initiation of breastfeeding if they received breastfeeding support from a health worker during pregnancy (OR: 0.79; 95% CI: 0.69, 0.92) or at birth (OR: 0.73; 95% CI: 0.60, 0.88). This gap was more likely to occur among those with a natural birth in the hospital (OR: 1.92; 95% CI: 1.50, 2.45), cesarean delivery (OR: 28.95; 95% CI: 20.1, 44.7), and breastfeeding difficulties (OR: 1.52; 95% CI: 1.21, 1.90). For EBF, the gap was lower among mothers with a higher social norm (OR: 0.20; 95% CI: 0.15, 0.27) or when they received breastfeeding support at birth by a health worker (OR: 0.82; 95% CI: 0.70, 0.95). In addition, intention of feeding infant formula at birth and having breastfeeding difficulties were associated with an increased gap in EBF [ORs (95% CIs): 1.28 (1.08, 1.51) and 1.29 (1.06, 1.57), respectively]. For continued breastfeeding at 1 y, social norms were associated with a lower gap (OR: 0.61; 95% CI: 0.41, 0.91), whereas breastfeeding difficulties were associated with an increased gap (OR: 1.70; 95% CI: 1.12, 2.57). CONCLUSION Reducing breastfeeding awareness-practice gaps requires strengthening breastfeeding support in health facilities and the sociocultural environment to make desired practices normative.
Progressive Injury in Chronic Multiple Sclerosis Lesions Is Gender-Specific: A DTI Study

Objective To evaluate the longitudinal integrity of white matter tracts in patients with relapsing remitting multiple sclerosis (RRMS) as determined by changes in diffusivity indices of lesional and non-lesional white matter in the optic radiation over 12 months. Methods The optic radiation (OR) was identified in sixty RRMS patients using probabilistic tractography. MS lesions were segmented on FLAIR T2 images and a lesion mask was intersected with the co-registered OR. Lesions within the OR were identified in 39 patients. Voxel-based analysis of axial diffusivity (AD) and radial diffusivity (RD) within OR lesions and non-lesional normal appearing white matter (NAWM) was performed at baseline and 12 months in 34 patients (five patients excluded due to new OR lesions). Results Both RD and AD demonstrated much higher values within the lesions compared with non-lesional NAWM. There was a significant (p<0.001) increase of lesional AD and RD during the follow-up period. This increase, however, was driven almost entirely by the male cohort, in which a significantly greater change in both AD (M-2.7%, F-0.9%) and RD (M-4.6%, F-0.7%) was observed during the follow-up period. Non-lesional NAWM also demonstrated an increase in both AD and RD, albeit on a much lesser scale (1.0% and 0.6% respectively). In contradistinction to lesions, the diffusivity change in non-lesional NAWM was similar between sexes. Conclusions The evolution of AD and RD in chronic MS lesions over 12 months suggests ongoing inflammatory demyelinating activity accompanied by axonal loss. In addition, our findings are consistent with the recently observed trend of more rapid clinical progression in males and establish a potential in vivo biomarker of gender dichotomy by demonstrating a significantly faster rate of microstructural change in the chronic lesions of male patients with MS.
Unruptured pregnancy in a noncommunicating rudimentary horn at 37 weeks with a live fetus: a case report

Abstract We report an extremely rare case of an unruptured non-communicating rudimentary horn full-term pregnancy. A woman who had a uterine malformation was misdiagnosed as uterus didelphys and gave birth to a live, healthy fetus. The correct diagnosis was not made until cesarean section at 37 4/7 weeks. The case suggests that women who are pregnant in a rudimentary horn could obtain a full-term delivery and give birth to a live and healthy baby.
PKCε, Via its Regulatory Domain and Independently of its Catalytic Domain, Induces Neurite-like Processes in Neuroblastoma Cells

To investigate the role of protein kinase C (PKC) isoforms in regulation of neurite outgrowth, PKCα, βII, δ, and ε fused to enhanced green fluorescent protein (EGFP) were transiently overexpressed in neuroblastoma cells. Overexpression of PKCε–EGFP induced cell processes whereas the other isoforms did not. The effect of PKCε–EGFP was not suppressed by the PKC inhibitor GF109203X. Instead, process formation was more pronounced when the regulatory domain was introduced. Overexpression of various fragments from PKCε regulatory domain revealed that a region encompassing the pseudosubstrate, the two C1 domains, and parts of the V3 region were necessary and sufficient for induction of processes. By deleting the second C1 domain from this construct, a dominant-negative protein was generated which suppressed processes induced by full-length PKCε and neurites induced during retinoic acid- and growth factor–induced differentiation. As with neurites in differentiated neuroblastoma cells, processes induced by the PKCε– PSC1V3 protein contained α-tubulin, neurofilament-160, and F-actin, but the PKCε–PSC1V3-induced processes lacked the synaptic markers synaptophysin and neuropeptide Y. These data suggest that PKCε, through its regulatory domain, can induce immature neurite-like processes via a mechanism that appears to be of importance for neurite outgrowth during neuronal differentiation.
The spatial concentration of bias: An examination of the community factors that influence residents’ perceptions of bias crime

Emerging scholarship indicates that bias crimes are concentrated in particular types of places. Currently, only a small number of studies consider the ecological factors that influence official reports of bias crime. Results from these studies indicate that the community processes and structures associated with the occurrence of non-bias crime may operate differently for bias crime. We use administrative and survey data from approximately 4000 residents living across 148 communities in Brisbane, Queensland to examine the ecological drivers of bias crime. Using multi-level logistic regression, we examine the community and household factors associated with residents’ perceptions of bias crime. Here, we focus not only on the structural demographics of the community, but also on the degree to which community cohesion influences whether or not residents perceive bias crime as a problem in their community. We find that poverty and ethnic diversity are positively associated with residents’ perceptions of bias crime. Further, residents living in communities with higher levels of community cohesion are less likely to perceive bias crime as a problem in their community. The level of community cohesion fully mediates the impact of ethnic diversity and partially mediates the effect of poverty on residents’ perceptions of bias crime.
Analysis of prostate tissue DNA for the presence of human papillomavirus by polymerase chain reaction, cloning, and automated sequencing

We have analysed the DNA from 24 prostate tissue biopsies, spanning a range of Gleason grading from benign to grade 5 and mixed randomly with cervical cancer samples of known human papillomavirus (HPV) status, for the prevalence of HPV DNA, in a double‐blind study to ensure complete objectivity. Polymerase chain reactions (PCR) were performed using general E1 open reading frame primers for HPV under low stringency conditions, in addition to reactions containing primers specific for HPV16, E2, and E6 open reading frames under higher, more stringent PCR conditions. The presence of cellular DNA was verified by the use of primers for hypoxanthine guanine phosphoribosyl transferase.
Finite-Set Model-Predictive Control Strategies for a 3L-NPC Inverter Operating With Fixed Switching Frequency

In this paper, finite-set model-predictive control (FS-MPC) methodologies for a grid-connected three-level neutral-point-clamped converter are investigated. The proposed control strategies produce fixed switching frequency, maintaining all the advantages of predictive control such as fast dynamic response, inclusion of nonlinearities and restrictions, and multivariable control using a single control loop. The first of the proposed FS-MPC strategies is based on a multiobjective cost function, designed to regulate both the inverter currents and the balancing of the dc-link capacitor voltages. The second FS-MPC strategy is derived from the first one, and it is based on a cost function that regulates only the grid current, with the balancing of the capacitor voltages being realized by controlling the duty cycles of the redundant vectors. The proposed control systems are experimentally validated using a 5-kW prototype. The experimental results show a good performance for both strategies, in steady-state and transient response, with a total harmonic distortion lower than $\text{2}\%$ for the currents supplied to the grid.
Coping variables as predictors of perioperative emotional states and adjustment

Abstract Surgery, regardless of its kind and severity, can be regarded as a major stress situation for any patient. High preoperative emotional arousal may negatively influence adaptation during surgery and, consequently, rate of postoperative recovery. In a series of previous studies, our research group analyzed the influence of dispositional and actual coping on subjective and objective stress indicators before, during, and after surgery. The present study investigates the influence of the dispositional coping variables vigilance and cognitive avoidance on actual surgery-related coping, state anxiety, and indicators of intra- and postoperative adjustment. The sample consisted of 42 male and 42 female patients undergoing elective maxillofacial surgery under general anaesthesia. Dispositional coping was measured on the dimensions vigilance and cognitive avoidance with the Mainz Coping Inventory. Actual surgery-related coping was assessed by means of a newly constructed inventory containing items to measur.
