The Effectiveness of Install-Time Permission Systems for Third-Party Applications

In many modern development platforms, application permissions control third-party access to sensitive parts of the API (e.g., the camera or microphone). We study install-time permissions, which the user grants to applications during installation; different applications can receive different installtime permissions. Install-time permissions offer several advantages over traditional user-based permissions, which assign the user’s full privileges to all applications. However, these benefits rely on the assumption that applications generally require less than full privileges. We explore whether that assumption is realistic, which provides insight into the value of install-time permission. We perform case studies on two systems with install-time permissions for third-party applications, the Google Chrome extension platform and the Android OS. We collect the permission requirements of a large set of Google Chrome extensions and Android applications. From this data, we evaluate whether install-time permissions are effective at protecting users. Our results indicate that install-time application permissions have a strong positive impact on system security, but a number of changes could further improve their utility.
Children as Citizens

Due to changing social conditions active citizenship becomes a dynamic process rather than a standard, clear-cut set of rights and responsibilities. Furthermore, childhood presents itself more and more as an ambivalent social phenomenon. On the one hand, children are seen as autonomous individuals, on the other hand, as objects of protection. Nevertheless, today children can be seen as active citizens. Their ability to learn and play allows them to give active meaning to their environment. Accepting playful and ambivalent forms of citizenship, child participation presents itself no longer as an utopia, but as a fact.
New-onset delusions and hallucinations in patients infected with HIV.

OBJECTIVE To assess the relationship between HIV-associated psychotic symptoms (i.e., delusions, hallucinations) and demographic, psychopathological and medical variables by comparing patients with and without cerebral opportunistic infections or metabolic encephalopathy. DESIGN Cross-sectional study. PATIENTS 26 patients admitted to hospital with HIV and new-onset psychotic symptoms, defined according to DSM-III-R criteria. OUTCOME MEASURES A semistructured psychiatric interview using the Psychopathology Assessment Scale (AMDP-4) of the Association for Methodology and Documentation in Psychiatry system. Comprehensive medical assessments, including laboratory tests and computed tomographic scans, were also performed. RESULTS Patients with cerebral opportunistic infections or metabolic encephalopathy (i.e., "secondary" psychosis, n = 13) were more likely to show disorders of consciousness, disorders of orientation and disturbances of attention and memory than those with no evidence of HIV-related cerebral disease (i.e., "primary" psychosis, n = 13); 10 patients (77%) with cerebral opportunistic infections or metabolic encephalopathy and only 1 (8%) patient without (p < 0.001) were diagnosed with delirium. These associations were stronger for the "secondary" patients with no focal brain lesions than for those with lesions. CONCLUSIONS These findings suggest that "organic" symptoms of psychosis in those infected with HIV are related to the systemic and cerebral complications of HIV infection rather than to the psychotic process itself.
Mast cell infiltrates in vulvodynia represent secondary and idiopathic mast cell hyperplasias

Mast cell infiltrates in tissues of vulvodynia are common, but they have not been characterized for criteria of neoplastic mast cell disease or correlated with patient's concomitant diseases associated with increased mast cells. Formalin‐fixed specimens of 35 patients with vulvodynia were evaluated immunohistochemically with antibodies to CD 3,4,8,20,117c and human mast cell tryptase, and for WHO‐criteria of neoplastic mastocytosis (>25% spindled mast cell, CD25 expression, point mutations of the c‐kit gene (D816V), and chronically elevated serum tryptase levels). Only 20/35 specimens showed a T‐lymphocyte dominant inflammatory infiltrate on HE‐stained sections, but all showed mast cells. 4/35 biopsies showed <10 mast cells/mm2, 15/35 specimens 40–60 mast cells/mm2 and 16/35 specimens >60 mast cells/mm2 (average 80/mm2). Control tissue contained typically <10 mast cells/mm2. Spindling, CD25‐expression, c‐kit gene mutations, or increased serum tryptase levels were not detected. 26/35 (74%) patients had concomitant autoimmune diseases, psoriasis, atopy, various allergies, preceding infections. Independent of the subtype of vulvodynia, the majority of mast cell rich biopsies with >40 mast cells/mm2 were classified as a secondary mast cell disorder reflecting an activated immune system in 75% of vulvodynia patients. Patients with increased mast cells may benefit from medical therapy targeting mast cells.
The role of emotions in L1 attrition: The case of Korean-English late bilinguals in New Zealand

This article explores the role of emotions in L1 attrition and L2 acquisition in a group of 30 Korean-English L1-dominant late bilinguals in New Zealand. The relationship between L1/L2 proficiency measures and emotion-related language choice (ERLC) is investigated using three measurement tools: a story-retelling task, a questionnaire, and a follow-up interview. The findings point to a shift from L1 to L2 and show this to be related to an increase in L2 fluency and a decrease in L1 accuracy. The findings also show an overall preference for ERLC to be in L1 rather than L2 and point to a strong relationship between ERLC and proficiency. Two other findings emerge from the data. Scores for ERLC relating to anger show different patterns, as well as those which express light emotional load. Follow-up interviews help explain these differences and add to our understanding of why the literature on ERLC among late bilinguals often appears contradictory.
A comparison of the peabody individual achievement test, the metropolitan achievement test, and the otis-lennon mental ability test†

In order to clarify the concurrent validity of the Peabody Individual Achievement Test (PIAT) and the Metropolitan Achievement Test (MAT), product-moment correlations were computed for all subscores and total scores for 26 normal-range public school third-grade girls and boys. The reading comprehension subtests correlated.81, spelling.88, and PIAT Mathematics with MAT Total Math.64. Correlations were computed for the Otis-Lennon Mental Ability Test and the PIAT General Information subtest as.77, and the Otis-Lennon and the PIAT Total Test scores as.79. Concurrent validity of the PIAT with both tests is tentatively considered adequate except in the area of mathematics, in which the PIAT, relative to the MAT, appears to be reflecting ability to handle math concepts (.68) more accurately than math computation (.41) or math problem solving (.56). Correlations with IQ partialed out suggest the PIAT Total Test, and PIAT and MAT reading and spelling measures, are relatively uninfluenced by IQ variations, whereas with IQ held constant, the weak positive correlations between the PIAT and MAT math subtests became essentially random relationships.
Movement Variability and its Implications for Sports Scientists and Practitioners: An Overview

This overview paper presents results from the studies of the various research groups with which I have been involved over the last decade that clearly show the existence of movement variability. I then address the possible functionality of movement variability. The important issue, particularly for practitioners, of whether such variability can be assessed in the conditions that pertain in competition is a major focus of the paper Unfortunately, current evidence suggests that we cannot measure movement variability in field conditions reliably or objectively, which prevents us from being able to address satisfactorily the possible implications that movement variability might pose for practitioners. Our major tasks, as sports biomechanists wishing to produce results that allow us to address issues that are relevant to coaches, are to develop accurate markerless tracking systems and to explore other measures of reliability that are more robust to measurement errors
Behavioral changes in albino rats due to repetitive heat stress of moderate level

Background: There are a number of studies showing the effect of severe heat stress on behaviour. Severe heat stress has been well reported to cause changes in activity level, attitude/mood, and behaviour. But, the effect of repetitive heat stress of moderate level on all these parameters has not been studied extensively. Aims & Objective: In the present study, the effect of repetitive heat stress of moderate level was assessed on activity level, attitude / mood, and behaviour (spontaneous and provoked) of adult albino male rats (wistar strain). Material and Methods: The experimental animals were subjected to repetitive heat stress for 4 hours daily, at 37±0.5oC in a Biological Oxygen Demand (BOD) incubator (relative humidity 65-82%) for five consecutive days. Daily changes were assessed in activity level during and after heat exposure and in attitude / mood along with behaviour (both spontaneous and provoked) after heat exposure in experimental animals and compared with control animals. Results: There was increased restlessness during heat exposure and decreased level of activity after heat exposure in experimental animals. The mood of the experimental animals was depressed and the experimental animals kept them isolated and did not respond on provoking after heat stress. Conclusion: All the above observations confirmed that exposure to repetitive heat stress, even of moderate level, causes significant change in behaviour of male albino rats.
Interpersonal bullying behaviours in the workplace

In this paper employing a phenomenological method to explicate seven informants’ experience of interpersonal bullying behaviors in a South African work context, I demarcated four general themes namely: lack of recognition, discrimination, obstructionism, and isolation. Moreover, I found that perpetrators (male and female managers) predominantly used verbal and indirect negative acts to bully subordinates. Finally, racial tensions contributed to bullying behavior. While a phenomenological approach shows promise to explore local bullying behavior more research is needed to broaden our understanding of the phenomenon, including explicating bullying through the eyes of bystanders and alleged bullies.
Working memory demands in insight versus analytic problem solving

Working memory is one of the cognitive processes thought to differentiate insight and analytic forms of problem solving. The present research examined memory involvement in the solution of insight versus analytic problems. Participants completed verbal and spatial working memory and short-term memory measures and a series of analytic and insight problems. Results demonstrated a relationship between working-memory capacity and the solution of analytic problems and between verbal short-term memory capacity and the solution of insight problems. This distinction was generally though not universally supported when memory was examined in relation to individual problems. Memory involvement in insight problem solving was further examined to clarify whether restructuring in insight is the end result of active memory search or spontaneous processes. The present research supports the theory that differences exist in the cognitive processes underlying insight versus analytic problem solving, and provides support for the spontaneous theory of restructuring in insight.
Code-switching functions in postcolonial classrooms

ABSTRACT This paper focuses on code-switching (CS) in postcolonial (P-C) classrooms (e.g. Africa, Asia and Asia-Pacific) where the use of English has increased not only as a subject matter, but also as the language of instruction across all subjects. CS, a common behaviour among bilinguals and polyglots, refers broadly to the alternation between two or more languages or language varieties in a single conversation, and has received much attention—in terms of both its grammatical dimensions and sociolinguistic function. Rather than focusing on the grammatical dimensions of CS, this paper examines the sociolinguistic functions. The paper highlights attitudinal conflicts between educational language policies and classroom practices in regard to CS. Supporters argue that CS facilitates language learning and creates a supportive classroom environment. Opponents argue that it is counterproductive, because it does not foster acquisition in the second (or additional) language. This paper examines this conflict and highlights how it plays out in P-C classroom contexts. The authors provide implication for both classroom practice and future research.
“You Can't Always Get What You Want”: A Novel Research Paradigm to Explore the Relationship between Multiple Intentions and Behaviours

Objective Research investigating cognitive moderators of the intention–behaviour relationship and psychological consequences of failure to enact intentions is usually conducted in a single‐behaviour paradigm. A multiple‐behaviour paradigm is introduced which overcomes bias inherent to single‐behaviour designs and allows testing of novel hypotheses. Two exploratory studies illustrate the utility of this new paradigm by investigating the role of cognitive predictors and psychological correlates of intention–behaviour relationships. Method The proposed method involves measuring multiple intentions across common areas of life activity at baseline and corresponding behaviours at follow‐up. In two studies, 51 intentions and behaviours were assessed (49 by self‐report, 2 objectively). In Study 1, participants (n = 126) also completed self‐reported measures of everyday cognitive failures and dysexecutive behaviours, crystallised intelligence (Mill Hill Vocabulary Scale) at baseline and Quality of Life (QoL; follow‐up). In Study 2, objective executive function measures (Stroop, Go/NoGo task and Word Fluency test) were completed by N = 30 participants. Results The total number of intentions, cognitive, and QoL measures were unrelated to the percentage of intentions enacted. Crystallised intelligence was related to successful intention implementation and problems with emotion regulation were associated with forming fewer intentions and with fewer failed intentions. QoL was strongly related with more intentions, regardless of whether or not these were implemented. Study 2 showed that cognitive flexibility (word fluency) and task errors, rather than Stroop effect and Go/No‐Go performance were related, to intention–behaviour congruence. Conclusion Intention–behaviour relationships might be better understood when considering the multiple intentions and behaviours that people are engaged in at once at any one point in time. A multiple‐behaviour paradigm suggests novel hypotheses. Preliminary findings reported here require replication. Anticipated applications of the paradigm are outlined and discussed.
3' -> 5' Exonucleases of DNA Polymerases ε and δ Correct Base Analog Induced DNA Replication Errors on opposite DNA Strands in Saccharomyces Cerevisiae

The base analog 6- N -hydroxylaminopurine (HAP) induces bidirectional GC → AT and AT → GC transitions that are enhanced in DNA polymerase ϵ and δ 3′ → 5′ exonuclease-deficient yeast mutants, pol2-4 and pol3-01 , respectively. We have constructed a set of isogenic strains to determine whether the DNA polymerases δ and ϵ contribute equally to proofreading of replication errors provoked by HAP during leading and lagging strand DNA synthesis. Site-specific GC → AT and AT → GC transitions in a Pol→, pol2-4 or pol3-01 genetic background were scored as reversions of ura3 missense alleles. At each site, reversion was increased in only one proofreading-deficient mutant, either pol2-4 or pol3-01 , depending on the DNA strand in which HAP incorporation presumably occurred. Measurement of the HAP-induced reversion frequency of the ura3 alleles placed into chromosome III near to the defined active replication origin ARS306 in two orientations indicated that DNA polymerases ϵ and δ correct HAP-induced DNA replication errors on opposite DNA strands.
The Limited Presence of African-American Teachers

The limited presence of talented African Americans in the teaching profession has been and continues to be a serious problem confronting the education profession and the African-American community in the United States. This review summarizes what is known from the research literature. It explores the reasons that African-American teachers are important as well as overall demographic, entry, and retention trends and the distinctive factors that influence the limited presence of African-American teachers. Finally, a suggested research agenda is presented.
Time-of-day affects prospective memory differently in younger and older adults

ABSTRACT The goal of this study was to investigate the impact of circadian arousal on prospective memory performance as a function of age. We tested a younger (18–34 years) and an older group (56–95 years) of participants on- and off-peak with regard to their circadian arousal patterns in a computer-based laboratory experiment. For the prospective memory task, participants had to press a particular key whenever specific target words appeared in an ongoing concreteness-judgment task. The results showed that prospective memory performance was better on- than off-peak in younger but not older participants. Younger participants consistently outperformed older participants in all conditions. We conclude that prospective remembering underlies time-of-day effects which most likely reflect controlled processes.
Family therapists’ adult attachment styles and the therapeutic alliance

Therapists’ adult attachment style may affect their ability to form effective therapeutic alliances. An analysis of semi-structured interviews with eleven family therapists explored the relationship between their adult attachment styles, as assessed using a self-report measure, and their perceptions of the therapeutic alliance. A framework analysis was employed, using four dimensions of the therapeutic alliance: engagement in the therapeutic process, emotional connection to the therapist, safety within the therapeutic system and shared sense of purpose within the family. Responses were compared between therapists with secure and insecure attachment styles according to different dimensions of the therapeutic alliance. There were no substantial differences in therapists’ accounts of their approach to engagement and creating a sense of safety; however they differed in their approaches to managing clients’ hostility. Secure and insecure therapists differed in one of the dimensions of therapeutic alliance; emotional connections to family members. Training and supervision could incorporate an understanding of attachment style. Suggestions are made for future research based on this exploratory study. Practitioner Points The ability to co-create a secure base may be related to the therapist's adult attachment style. Therapists with insecure attachment styles appear to have difficulty in managing clients’ hostility and close emotional connections. Trainees may benefit from understanding their own adult attachment styles and resolving outstanding family-of-origin issues. Clinical supervision could reflect on the interaction between the therapist's and family attachment styles.
Reduction of myocardial reperfusion injury by intravenous adenosine administered during the early reperfusion period.

Adenosine influences the function of several cell types thought to be involved in the pathogenesis of myocardial reperfusion injury. We have previously demonstrated that intracoronary administration of adenosine enhances myocardial salvage 24 hours after reperfusion. To determine if these beneficial effects could be obtained during a prolonged period of reperfusion using an intravenous route of administration, 22 closed-chest dogs were subjected to 90 minutes of proximal left anterior descending coronary artery occlusion and 72 hours of reperfusion. Animals randomly received either intravenous adenosine (0.15 mg/kg/min) or an equal volume of Ringer's lactate during the first 150 minutes of reperfusion. The area at risk was defined in vivo with Monastral blue, and infarct size was measured histologically with Mallory's trichrome stain. Serial global and regional ventricular function were determined with contrast ventriculography and analyzed using a computerized radial shortening method. Biopsies were obtained from the central ischemic zone to assess endothelial ultrastructure and capillary obstruction. No significant effects in heart rate or blood pressure were noted during adenosine infusion. Transmural collateral blood flow during ischemia was similar in the groups. Infarct size expressed as a percentage of the anatomical area at risk was significantly less in the adenosine-treated group (35.3 +/- 4.3% in controls versus 17.1 +/- 4.3% in treated animals, p less than 0.01). A progressive decrease in transmural blood flow was noted in control animals during reperfusion, resulting in a significant reduction at 3 hours compared with the preocclusion value (0.69 +/- 0.11 ml/min/g [at baseline versus 0.45 +/- 0.10 ml/min/g at 3 hours, p less than 0.05]). In contrast, flow in adenosine animals at 3 hours was similar to baseline values (0.91 +/- 0.15 ml/min/g at baseline versus 0.98 +/- 0.14 ml/min/g at 3 hours, p = NS) and was significantly higher (p less than 0.05) than the control group. Radial shortening in the ischemic zone was significantly improved at 3 (-2.6 +/- 2.8% in controls versus 11.6 +/- 3.3% in treated animals, p less than 0.01) and 72 hours (5.5 +/- 2.0% in controls versus 17.3 +/- 3.5% in treated animals, p less than 0.01) after reperfusion in treated animals. Electron microscopy showed reduced neutrophil and erythrocyte plugging of capillaries with relative preservation of endothelial cell structure in the adenosine group.

Highly active antiretroviral therapy for critically ill HIV patients: A systematic review and meta-analysis

Introduction It is unclear whether the treatment of an HIV infection with highly active antiretroviral therapy (HAART) affects intensive care unit (ICU) outcomes. In this paper, we report the results of a systematic review and meta-analysis performed to summarize the effects of HAART on the prognosis of critically ill HIV positive patients. Materials and methods A bibliographic search was performed in 3 databases (PubMed, Web of Science and Scopus) to identify articles that investigated the use of HAART during ICU admissions for short- and long-term mortality or survival. Eligible articles were selected in a staged process and were independently assessed by two investigators. The methodological quality of the selected articles was evaluated using the Methodological Index for Non-Randomized Studies (MINORS) tool. Results Twelve articles met the systematic review inclusion criteria and examined short-term mortality. Six of them also examined long-term mortality (≥90 days) after ICU discharge. The short-term mortality meta-analysis showed a significant beneficial effect of initiating or maintaining HAART during the ICU stay (random effects odds ratio 0.53, p = 0.02). The data analysis of long-term outcomes also suggested a reduced mortality when HAART was used, but the effect of HAART on long-term mortality of HIV positive critically ill patients remains uncertain. Conclusions This meta-analysis suggests improved survival rates for HIV positive patients who were treated with HAART during their ICU admission.
