Switching Trains of Thought

This study investigated how journalistic story frames can affect the thoughts and feelings of readers. Two hundred and seventy-eight students participated in two studies, reading and responding to a fictitious story about possible reductions in state funding of their university. Stories were presented in one of four randomly assigned versions, all containing the same information, but varying in their opening and closing paragraphs according to the frame employed: human interest, conflict, or personal consequences. A control version contained the common body only. In Study 1, thoughts listed by participants indicated that the news frames—although they had no influence on the volume of cognitive responses—significantly affected the topical focus and evaluative implications of thoughts generated. In Study 2, evaluations and opinions offered by participants indicated that the news frames also subtly could affect audience decision making about matters of public policy. Implications for shaping public opinion are discussed.
Endocytosis of GPI-linked membrane folate receptor-alpha

GPI-linked membrane folate receptors (MFRs) have been implicated in the receptor-mediated uptake of reduced folate cofactors and folate-based chemotherapeutic drugs. We have studied the biosynthetic transport to and internalization of MFR isoform alpha in KB-cells. MFR-alpha was synthesized as a 32-kD protein and converted in a maturely glycosylated 36-38-kD protein 1 h after synthesis. 32-kD MFR-alpha was completely soluble in Triton X-100 at 0 degree C. In contrast, only 33% of the 36- 38-kD species could be solubilized at these conditions whereas complete solubilization was obtained in Triton X-100 at 37 degrees C or in the presence of saponin at 0 degree C. Similar solubilization characteristics were found when MFR-alpha at the plasma membrane was labeled with a crosslinkable 125I-labeled photoaffinity-analog of folic acid as a ligand. Triton X-100-insoluble membrane domains containing MFR-alpha could be separated from soluble MFR-alpha on sucrose flotation gradients. Only Triton X-100 soluble MFR-alpha was internalized from the plasma membrane. The reduced-folate-carrier, an integral membrane protein capable of translocating (anti-)folates across membranes, was completely excluded from the Triton X-100- resistant membrane domains. Internalized MFR-alpha recycled slowly to the cell surface during which it remained soluble in Triton X-100 at 0 degree C. Using immunoelectron microscopy, we found MFR-alpha along the entire endocytic pathway: in clathrin-coated buds and vesicles, and in small and large endosomal vacuoles. In conclusion, our data indicate that a large fraction, if not all, of internalizing MFR-alpha bypasses caveolae.
Quantum revivals in two degrees of freedom integrable systems: The torus case

The paper deals with the semi-classical behaviour of quantum dynamics for a semi-classical completely integrable system with two degrees of freedom near Liouville regular torus. The phenomomenon of wave packet revivals is demonstrated in this article. The framework of this paper is semi-classical analysis (limit :). For the proofs we use standard tools of real analysis, Fourier analysis and basic analytic number theory.
Significance of log-periodic precursors to financial crashes

We clarify the status of log-periodicity associated with speculative bubbles preceding financial crashes. In particular, we address Feigenbaum's criticism ([A article="1469-7688/1/3/306"] Feigenbaum J A 2001 Quantitative Finance 1 346-60 [/A]) and show how it can be refuted. Feigenbaum's main result is as follows: 'the hypothesis that the log-periodic component is present in the data cannot be rejected at the 95% confidence level when using all the data prior to the 1987 crash; however, it can be rejected by removing the last year of data' (e.g. by removing 15% of the data closest to the critical point). We stress that it is naive to analyse a critical point phenomenon, i.e., a power-law divergence, reliably by removing the most important part of the data closest to the critical point. We also present the history of log-periodicity in the present context explaining its essential features and why it may be important. We offer an extension of the rational expectation bubble model for general and arbitrary risk-aversion within the general stochastic discount factor theory. We suggest guidelines for the use of log-periodicity and explain how to develop and interpret statistical tests of log-periodicity. We discuss the issue of prediction based on our results and the evidence of outliers in the distribution of drawdowns. New statistical tests demonstrate that the 1% to 10% quantile of the largest events of the population of drawdowns of the NASDAQ composite index and of the Dow Jones Industrial Average index belong to a distribution significantly different from the rest of the population. This suggests that very large drawdowns may result from an amplification mechanism that may make them more predictable.
Anti-Immigrant Prejudice in Europe: Contact, Threat Perception, and Preferences for the Exclusion of Migrants

This article introduces the theoretical approaches of contact, group conflict, and symbolic prejudice to explain levels of exclusionary feelings toward a relatively new minority in the West European context, the immigrant. The findings indicate that even after controls for perceived threat are included in the model, intimate contact with members of minority groups in the form of friendships can reduce levels of willingness to expel legal immigrants from the country. A contextual variable, level of immigration to the country, is also introduced into the model because it is likely that this variable affects both threat perception and exclusionary feelings. While context does not seem to directly affect levels of willingness to expel or include immigrants in the society, it does have a rather powerful impact on perceived threat. Perhaps even more importantly, the findings suggest that contact mediates the effect of the environment, helping to produce lower levels of threat perception in contexts of high immigration.
Cost and outcome of treatment of adults with acute myeloid leukemia at the National Cancer Institute-Egypt.

BACKGROUND Despite important advances in the therapy of acute myeloid leukemia (AML), the majority of patients die of their disease, unless bone marrow transplantation (BMT) is done. Infection and hemorrhage are still the major causes of mortality in AML patients. Progress in therapy and supportive care has led to gradual improvement in the overall results, but further improvements are still needed. PATIENTS AND METHODS The aim of this study is to identify the outcome and costs of adult AML patients treated with conventional chemotherapy (CCT) at the National Cancer Institute (NCI), Cairo University during the time period from April 1999 to January 2002. Clinical, laboratory characteristics were all recorded. Data regarding different types of therapies given for these patients including response, outcome and costs were also collected. RESULTS The median age of 82 identified AML patients was 34 years. The complete remission (CR) rate after induction with CCT was 52% (42/82 patients) with a median CR duration of 9 months. Twenty-eight percent of patients who achieved CR subsequently relapsed. By January 2003, fifty-eight patients were dead (70.7%). Infections were the major mortality cause, followed by disease progression then bleeding (65% , 28% and 7% respectively). The median treatment cost per patient was 33158 Egyptian Pounds (LE). It was higher for patients who achieved CR compared to those who relapsed and/or died. Drugs contributed by 78 % to the total treatment cost, while hospitalization, investigations and blood-component therapy contributed by 6%, 7% and 8% respectively. CONCLUSIONS Outcome of patients with AML treated at NCI- Cairo University can be enhanced by improvement of supportive therapy; mainly infection control and expanding BMT programs to accommodate all eligible patients.
Some Refinements on Peer Assessment of Group Projects

As the demand for group projects in higher education has increased in recent years, it is necessary to device an assessment method that results in fair grading of project group members. An attempt has been made to apply an existing peer assessment approach from Goldfinch to engineering student group projects. The results confirm the validity of the approach. However, the existing approach has a number of problems owing to the inevitable bias introduced by individual students during the peer assessment process. A new normalisation process is introduced to iron out the inherent shortcomings of the existing peer assessment method. The experience gained so far has led us to believe that this peer assessment method with normalisation can be used as a tool to assess individual marks of a group project.
Authentic Leadership and Follower Development

This article contributes to the theoretical understanding of the relationship between authentic leadership and follower psychological capital. Structural equation models using a representative national sample of working adults revealed a positive relationship between authentic leadership and followers’ psychological capital, partially mediated by positive work climate, and a significant moderating effect from gender. Findings support previous predictions about the effects of authentic leadership and begin to reveal the mechanisms by which authentic leaders affect followers. Moreover, they underscore the need to consider the influence of follower characteristics in understanding leadership outcomes. Implications and directions for future research are discussed.
Genotype‐by‐environment interactions due to antibiotic resistance and adaptation in Escherichia coli

Mutations that are beneficial in one environment can have different fitness effects in other environments. In the context of antibiotic resistance, the resulting genotype‐by‐environment interactions potentially make selection on resistance unpredictable in heterogeneous environments. Furthermore, resistant bacteria frequently fix additional mutations during evolution in the absence of antibiotics. How do these two types of mutations interact to determine the bacterial phenotype across different environments? To address this, I used Escherichia coli as a model system, measuring the effects of nine different rifampicin resistance mutations on bacterial growth in 31 antibiotic‐free environments. I did this both before and after approximately 200 generations of experimental evolution in antibiotic‐free conditions (LB medium), and did the same for the antibiotic‐sensitive wild type after adaptation to the same environment. The following results were observed: (i) bacteria with and without costly resistance mutations adapted to experimental conditions and reached similar levels of competitive fitness; (ii) rifampicin resistance mutations and adaptation to LB both indirectly altered growth in other environments; and (iii) resistant‐evolved genotypes were more phenotypically different from the ancestor and from each other than resistant‐nonevolved and sensitive‐evolved genotypes. This suggests genotype‐by‐environment interactions generated by antibiotic resistance mutations, observed previously in short‐term experiments, are more pronounced after adaptation to other types of environmental variation, making it difficult to predict long‐term selection on resistance mutations from fitness effects in a single environment.
Microhardness and Ca:P ratio of carious and Carisolv treated caries-affected dentine using an ultra-micro-indentation system and energy dispersive analysis of x-rays--a pilot study.

BACKGROUND This study aimed to evaluate microhardness and chemical analysis of carious and caries-affected dentine. The hypothesis tested was that calcium:phosphorous (Ca:P) ratios correlate with microhardness values. METHODS Four carious human third molars were sectioned through the caries lesion in the mesiodistal longitudinal plane. One half of each lesion underwent carious dentine removal using Carisolv gel. The cut surfaces were polished, microhardness tested using an Ultra-Micro-Indentation System (UMIS) and elemental analysis performed using energy dispersive analysis of x-rays (EDAX). RESULTS The microhardness of carious dentine decreased gradually towards the cavity floor, but that for caries-affected dentine showed more variation with depth, having a mean hardness of (0.63 +/- 0.18) GPa. Ca:P ratios of carious dentine varied among the four specimens. The mean Ca:P ratio of caries-affected dentine was 1:2.03 +/- 0.08. The hypothesis was accepted for active lesions. CONCLUSIONS The use of Carisolv to excavate carious tissue can be as effective as rotary instrumentation.
Genetic variations associated with psoriasis and psoriatic arthritis found by genome‐wide association

Psoriasis and psoriatic arthritis are immune disorders with a complex polygenic basis. HLA‐Cw6, which lies in the major histocompatibility region on chromosome 6, is considered the major genetic determinant of psoriasis. Recent genome‐wide association studies have identified new variants outside of the MHC with relevance to the immunology of psoriasis. Variants in or near genes that encode subunits of cytokines (IL12B, IL23A) or cytokine receptors (IL23R) are interesting given that the gene product of IL12B, p40, is the target of a recently approved monoclonal antibody therapy for psoriasis (ustekinumab). Association with psoriasis and psoriatic arthritis has been found in TNFAIP3 and TNFIP1, ubiquitin ligases in the NF‐κB pathway, and IL13, a Th2 cytokine. Copy number variation of human beta‐defensin and late cornified envelope genes also associate with psoriasis. Many of these genetic variations also associate with immune disorders considered psoriatic co‐morbidities, including Crohn's disease and diabetes.
Cryo‐FIB‐nanotomography for quantitative analysis of particle structures in cement suspensions

Cryo‐FIB‐nanotomography is a novel high‐resolution 3D‐microscopy technique, which opens new possibilities for the quantitative microstructural analysis of complex suspensions. In this paper, we describe the microstructural changes associated with dissolution and precipitation processes occurring in a fresh cement paste, which has high alumina and sulphate contents. During the first 6 min, precipitation of ettringite leads to a general decrease of the particle size distribution. In the unhydrated cement paste almost no particles smaller than 500 nm are present, whereas after 6 min this size class already represents 9 vol%. The precipitation of ettringite also leads to a significant increase of the particle number density from 0.294*109/mm3 at t0min to 20.55*109/mm3 at t6min. Correspondingly the surface area increases from 0.75 m2/g at t0min to 2.13 m2/g at t6min. The small ettringite particles tend to form agglomerates, which strongly influence the rheological properties. The particular strength of cryo‐FIB‐nt is the potential to quantify particle structures in suspension and thereby also to describe higher‐order topological features such as the particle–particle interfaces, which is important for the study of agglomeration processes.
Evaluating the Effects of Information Technology on Problem-Oriented-Policing

Technologies promise to make our organizations more productive, efficient or effective. But our experience does not always fulfill this promise. Public safety agencies are the target of a barrage of new information technologies offering better performance, many of which are attractive because they can be financed through federal grants. But when evaluations are performed of these technologies, improvements do not always result. This article describes the experiences of a state police agency (SPA) during its use of cellular digital packet data (CDPD) systems to support its problem-oriented policing (POP) project. The CDPD system should have improved the SPA's POP operations; in practice, it was not as clear. Although participants believed the CDPD technology worthwhile, there were only a few minor differences between POP officers that did and did not use it. This evaluation suggests the need for better databases to measure performance as well as more informed federal funding of ways to assess the impact of technologies.
Social Networks of Refugees in the United Kingdom: Tradition, Tactics and New Community Spaces

This study is based on three years of participative, ethnographic fieldwork with asylum-seekers and refugees in the United Kingdom. Through participant observation and analysis of ego-centred networks, I attempted to build trusting research relationships with individual refugees coming to terms with life in exile. Refugees themselves have played an integral part in the innovative research design which has evolved in response to their contributions. The research demonstrates that, contrary to some stereotypes, refugees endeavour to be proactive social actors. This counters the predominant assumption of refugee dependency. Furthermore, the research adds to existing work on the social networks of refugees by providing an intimate picture of a small group of refugees. It describes their tactics in meeting practical and emotional needs, describes how these networks spread across continents and from home country to countries of exile, and proposes a new typology based on the strength of network ties:
Mental Model Updating and Team Adaptation

In this article, we build on theories of team adaptation by exploring the role of team members’ cognitive knowledge structures in team adaptation to a changing task context. We introduce the notion of mental model updating as the extent to which team members update their mental models in reaction to a change in the task situation. In a laboratory study we investigate the relations between initial mental model similarity and accuracy, team mental model updating, the development of novel interaction patterns, and postchange team performance. The results indicate that mental model updating is positively related to postchange team performance. Also, team adaptation patterns accounted for the effect of mental model updating on postchange team performance. We did not find evidence for a positive relation between initial mental model similarity and accuracy and mental model updating.
Resilience for all: a study of classrooms as protective contexts

Educational resilience has received considerable attention in the literature in the past three decades, with particular reference to indicated and selective interventions. This paper construes resilience within a generalist, universal perspective and examines how classrooms may serve as protective and competence‐enhancing contexts for all their students. Various processes, such as caring relationships, active engagement, inclusion, collaboration, positive beliefs and expectations, and recognition, were identified in a naturalist study of Maltese primary school classrooms operating as optimal learning environments. The study suggests that classrooms, which organize themselves as caring, inclusive and learning and pro‐social centred communities, may operate as protective and competence‐enhancing contexts for all their students.
Political Correctness, Selection Bias, and the NCAA Basketball Tournament

Allegations of selection bias toward the major conferences and teams with committee representation have previously been levied on the National Collegiate Athletic Association (NCAA) Basketball tournament selection committee. We illustrate the source of this bias is political correctness. When using the computer ranking of Ratings Percentage Index (RPI), which uses only wins and losses in its analysis, bias in the selection process seems evident. No bias is revealed when the Sagarin “Predictor” rating is substituted for RPI. The Sagarin “Predictor” rating uses margin of victory and results compared to expectations in its analysis; the selection committee appears to use the same factors when determining at-large bids.
Antifungal Resistance of Candida glabrata Vaginal Isolates and Development of a Quantitative Reverse Transcription-PCR-Based Azole Susceptibility Assay

ABSTRACT A multiplex quantitative reverse transcription-PCR assay was developed to detect azole resistance in Candida glabrata, an important opportunistic pathogen that develops resistance rapidly. Resistance was defined as a ≥3-fold increase in CDR1 expression by this assay, which proved to be 100% sensitive and 95% specific in comparison to the gold standard broth microdilution assay.
Pluralist discourses of bilingualism and translanguaging talk in classrooms

This paper examines student and teacher talk in a first grade classroom in a two-way immersion school in Central Texas. Drawing on audio and video data from a year-long study in a first grade two-way classroom and using a methodology that fuses ethnography and discourse analysis, the authors explore how pluralist discourses are constructed and lived in by bilingual students and teachers. These findings have implications for understanding the ways in which teachers and students are influenced by language policy, as well as how they might either support or undermine that policy.
Predictors Factors of Low Bone Mineral Density in Dental Panoramic Radiographs

Osteoporosis is a systemic disease that is considered a public health problem since it presents socioeconomic impacts. The disease results in micro architectural deterioration of bone tissue and decrease of bone mineral density (BMD) with consequent increase of bone fragility and susceptibility to fractures. Dual energy X-ray absorptiometry (DXA) is considered the gold standard for BMD evaluation, but investigations about several panoramic radiography indices have been done in order to seek a predictor of low BMD so that the dentist can play an important role in screening patients with low BMD and referring them properly for bone densitometry for osteoporosis investigation. The aim of this paper is to present a review of mandibular radio morphometric indices evaluated in dental panoramic radiographies and used to recognize patients with low BMD.
Influences of Gender Stereotypes on Adolescents’ Perceptions of Their Own Achievement

This study of Australian students’ perceptions of achievement argues for flexibility in gender stereotypes, varying with the frame of reference, and the multidimensionality of self-concepts. Students in the first 4 years of high school (N = 663) completed tests and questionnaires about mathematics and English. The systematic patterns of their responses depended on contrasting subject domains and the specific or general nature of aspects of their achievement. Gender differences in how well students thought they performed were at odds with similar performances on standardized tests. Two sources of gender stereotypes explain complex interactions of gender and subject domain for interrelated aspects of achievement—a tendency by males to overestimate specific task performance across domains, and traditional gender stereotypes about “natural talent” for females in English and for males in mathematics. The broad implications for ways we think about mathematics and gender require an understanding of discrete notions of ability and performance, and an acknowledgment of students’ flexible self-categorizations.
