Effects of Contextual Sight-Singing and Aural Skills Training on Error-Detection Abilities

Effects of contextual sight-singing and ear training on pitch and rhythm error detection abilities among undergraduate instrumental music education majors were examined. Experimental (n1 = 15) and control (n2 = 15) groups received identical training in instrumental methods and conducting. Experimental subjects additionally received 50 minutes of sight-singing and ear training per week over 11 weeks using materials drawn from extant band repertoire. Subject responses to errors in one-, two-, and three-part homorhythmic and polyrhythmic examples were examined. Results showed significant differences in correct detection of rhythm and pitch errors. Experimental subjects were better at error detection compared to control subjects. Subjects were better at detecting rhythm errors compared to pitch errors. They were best with one-part, did less well with two-part, and least well with three-part examples. Differences attributable to texture were not significant. Contextual sight-singing and aural skills training and practice may have contributed to short-term development of error-detection abilities.
Are Neighborhood-Level Characteristics Associated with Indoor Allergens in the Household?

Background: Individual home characteristics have been associated with indoor allergen exposure; however, the influence of neighborhood-level characteristics has not been well studied. We defined neighborhoods as community districts determined by the New York City Department of City Planning. Objective: We examined the relationship between neighborhood-level characteristics and the presence of dust mite (Der f 1), cat (Fel d 1), cockroach (Bla g 2), and mouse (MUP) allergens in the household. Methods: Using data from the Puerto Rican Asthma Project, a birth cohort of Puerto Rican children at risk of allergic sensitization (n = 261), we examined associations between neighborhood characteristics (percent tree canopy, asthma hospitalizations per 1,000 children, roadway length within 100 meters of buildings, serious housing code violations per 1000 rental units, poverty rates, and felony crime rates), and the presence of indoor allergens. Allergen cutpoints were used for categorical analyses and defined as follows: dust mite: >0.25 μg/g; cat: >1 μg/g; cockroach: >1 U/g; mouse: >1.6 μg/g. Results: Serious housing code violations were statistically significantly positively associated with dust mite, cat, and mouse allergens (continuous variables), adjusting for mother's income and education, and all neighborhood-level characteristics. In multivariable logistic regression analyses, medium levels of housing code violations were associated with higher dust mite and cat allergens (1.81, 95%CI: 1.08, 3.03 and 3.10, 95%CI: 1.22, 7.92, respectively). A high level of serious housing code violations was associated with higher mouse allergen (2.04, 95%CI: 1.15, 3.62). A medium level of housing code violations was associated with higher cockroach allergen (3.30, 95%CI: 1.11, 9.78). Conclusions: Neighborhood-level characteristics, specifically housing code violations, appear to be related to indoor allergens, which may have implications for future research explorations and policy decisions.
The Phosphoinositide Signal Transduction System Is Impaired in Bipolar Affective Disorder Brain

Abstract: The function of the phosphoinositide second messenger system was assessed in occipital, temporal, and frontal cortex obtained postmortem from subjects with bipolar affective disorder and matched controls by measuring the hydrolysis of [3H]phosphatidylinositol ([3H]PI) incubated with membrane preparations and several different stimulatory agents. Phospholipase C activity, measured in the presence of 0.1 mM Ca2+ to stimulate the enzyme, was not different in bipolar and control samples. G proteins coupled to phospholipase C were concentration‐dependently activated by guanosine 5′‐O‐(3‐thiotriphosphate) (GTPγS) and by NaF. GTPγS‐stimulated [3H]PI hydrolysis was markedly lower (50%) at all tested concentrations (0.3–10 µM GTPγS) in occipital cortical membranes from bipolar compared with control subjects. Responses to GTPγS in temporal and frontal cortical membranes were similar in bipolars and controls, as were responses to NaF in all three regions. Brain lithium concentrations correlated directly with GTPγS‐stimulated [3H]PI hydrolysis in bipolar occipital, but not temporal or frontal, cortex. Carbachol, histamine, trans‐1‐aminocyclopentyl‐1,3‐dicarboxylic acid, serotonin, and ATP each activated [3H]PI hydrolysis above that obtained with GTPγS alone, and these responses were similar in bipolars and controls except for deficits in the responses to carbachol and serotonin in the occipital cortex, which were equivalent to the deficit detected with GTPγS alone. Thus, among the three cortical regions examined there was a selective impairment in G protein‐stimulated [3H]PI hydrolysis in occipital cortical membranes from bipolar compared with control subjects. These results directly demonstrate decreased activity of the phosphoinositide signal transduction system in specific brain regions in bipolar affective disorder.
Sex Differences in the Association of Childhood Socioeconomic Status With Adult Blood Pressure Change: The CARDIA Study

Objective To examine sex differences in the relation of childhood socioeconomic status (CSES) to systolic (SBP) and diastolic blood pressure (DBP) trajectories during 15 years, spanning young (mean [M] [standard deviation {SD}] = 30 [3] years) and middle (M [SD] = 45 [3] years) adulthood, independent of adult SES. Methods A total of 4077 adult participants reported father’s and mother’s educational attainments at study enrollment (Year 0) and own educational attainment at enrollment and at all follow-up examinations. Resting BP also was measured at all examinations. Data from examination Years 5 (when participant M [SD] age = 30 [3] years), 7, 10, 15, and 20 are examined here. Associations of own adult (Year 5), mother’s, and father’s educations with 15-year BP trajectories were examined in separate multilevel models. Fully controlled models included time-invariant covariates (age, sex, race, recruitment center) and time-varying covariates that were measured at each examination (marital status, body mass, cholesterol, oral contraceptives/hormones, and antihypertensive drugs). Analyses of parental education controlled for own education. Results When examined without covariates, higher education — own (SBP &ggr; = −0.03, DBP &ggr; = −0.03), mother’s (SBP &ggr; = −0.02, DBP &ggr; = −0.02), and father’s (SBP &ggr; = −0.02, DBP &ggr; = −0.01) — were associated with attenuated 15-year increases in BP (p < .001). Associations of own (but not either parent’s) education with BP trajectories remained independent of standard controls. Sex moderated the apparent null effects of parental education, such that higher parental education—especially mother’s, predicted attenuated BP trajectories independent of standard covariates among women (SBP &ggr; = −0.02, p = .02; DBP &ggr; = −0.01, p = .04) but not men (SBP &ggr; = 0.02, p = .06; DBP &ggr; = 0.005, p = .47; p interaction SBP < .001, p interaction DBP = .01). Conclusions Childhood socioeconomic status may influence women’s health independent of their own adult status.

Short-Term Attentional Perseveration Associated with Real-Life Creative Achievement

There are at least two competing hypotheses of how attention interacts with creative cognition, although they are not mutually exclusive. The first hypothesis is that highly creative people are particularly flexible at switching their attention – that is, they adaptively shift focus among different attentional levels using cognitive control. The second, less common, view is that creative people exhibit attentional persistence, or an ability for sustained attention. We suggest these two views need not be competing, as they may both operate, but on different time scales or on different components of creativity. In the present study we examined the role of attention in real-world creative achievement and in divergent thinking. In Experiment 1 participants with high and low real-world creative achievements identified whether the stimulus contained letters S or H within hierarchically constructed letters (e.g., large S made of small Es – global level; large E made up of small Ss – local level), which were presented in blocks of eight trials per level. In Experiment 2 participants with high, medium, and low creative achievements identified the same stimulus letters, but in blocks of five, seven, and nine trials per level. Results from both experiments indicated that people with high creative achievements made significantly more errors on trials in which they had to switch the level of attention, even after controlling for general intelligence. In Experiment 2, divergent thinking was also assessed, but it was not related to switching cost. Results from both experiments demonstrate that real-world creative acts relate to increased levels of attentional persistence, even if it comes with the cost of perseveration in certain circumstances.
Resistance of Undisturbed Soil Microbiomes to Ceftriaxone Indicates Extended Spectrum β-Lactamase Activity

Emergence and spread of antibiotic resistance, and specifically resistance to third generation cephalosporins associated with extended spectrum β-lactamase (ESBL) activity, is one of the greatest epidemiological challenges of our time. In this study we addressed the impact of the third generation cephalosporin ceftriaxone on microbial activity and bacterial community composition of two physically and chemically distinct undisturbed soils in highly regulated microcosm experiments. Surprisingly, periodical irrigation of the soils with clinical doses of ceftriaxone did not affect their microbial activity; and only moderately impacted the microbial diversity (α and β) of the two soils. Corresponding slurry experiments demonstrated that the antibiotic capacity of ceftriaxone rapidly diminished in the presence of soil, and ∼70% of this inactivation could be explained by biological activity. The biological nature of ceftriaxone degradation in soil was supported by microcosm experiments that amended model Escherichia coli strains to sterile and non-sterile soils in the presence and absence of ceftriaxone and by the ubiquitous presence of ESBL genes (blaTEM, blaCTX-M, and blaOXA) in soil DNA extracts. Collectively, these results suggest that the resistance of soil microbiomes to ceftriaxone stems from biological activity and even more, from broad-spectrum β-lactamase activity; raising questions regarding the scope and clinical implications of ESBLs in soil microbiomes.
Patching Physical Objects

Personal fabrication is currently a one-way process: Once an object has been fabricated with a 3D printer, it cannot be changed anymore; any change requires printing a new version from scratch. The problem is that this approach ignores the nature of design iteration, i.e. that in subsequent iterations large parts of an object stay the same and only small parts change. This makes fabricating from scratch feel unnecessary and wasteful. In this paper, we propose a different approach: instead of re-printing the entire object from scratch, we suggest patching the existing object to reflect the next design iteration. We built a system on top of a 3D printer that accomplishes this: Users mount the existing object into the 3D printer, then load both the original and the modified 3D model into our software, which in turn calculates how to patch the object. After identifying which parts to remove and what to add, our system locates the existing object in the printer using the system's built-in 3D scanner. After calibrating the orientation, a mill first removes the outdated geometry, then a print head prints the new geometry in place. Since only a fraction of the entire object is refabricated, our approach reduces material consumption and plastic waste (for our example objects by 82% and 93% respectively).

A SLA-Oriented Management of Containers for Hosting Stateful Web Services

Service-oriented architectures provide integration of interoperability for independent and loosely coupled services. Web services and the associated new standards such as WSRF are frequently used to realise such service-oriented architectures. In such systems, autonomic principles of self-configuration, self-optimisation, self-healing and self- adapting are desirable to ease management and improve robustness. In this paper we focus on the extension of the self management and autonomic behaviour of a WSRF container connected by a structured P2P overlay network to monitor and rectify its QoS to satisfy its SIAs. The SLA plays an important role during two distinct phases in the life-cycle of a WSRF container. Firstly during service deployment when services are assigned to containers in such a way as to minimise the threat of SLA violations, and secondly during maintenance when violations are detected and services are migrated to other containers to preserve QoS. In addition, as the architecture has been designed and built using standardised modern technologies and with high levels of transparency, conventional Web services can be deployed with the addition of a SLA specification.
CROSS-CLASS PERCEPTIONS OF SOCIAL CLASS

This article explores how members of the American middle and working classes perceive themselves and each other's lives. The data offer an opportunity to address the relevance of social class as a concept for understanding American society while at the same time helping to clarify the debate over the question of whether the working class is integrated into American society or angry, alienated, and resistant to mainstream goals and institutions. The data reported here suggest that the attitudes held by many members of the middle class, which members of the working class perceive during social interaction, have an impact on the self-confidence of working-class individuals, causing some of them to experience self-doubt, pain, and hidden injuries. Social class as defined by education, occupational prestige, and income still matters in the United States. The American working class may not be class conscious in the classic Marxian sense of the concept - a class for itself - but it does have a deep understanding of the inequalities between "us" and "them". The respondents in this study do not yet know they live in a postmodern world. The attitudes and actions of members of the middle class toward working-class culture help (re) create the American working class.
Gender‐specific peer groups and choice at 16

The purpose of this paper is to examine the influence of gender‐specific peer groups on students’ intentions and realisations to stay on into post‐compulsory education at the age of 16. This is an important area for research as one of the UK government’s aims is to achieve a 50% staying on rate in higher education at the age of 16. However, this might not be achievable because it is demand‐constrained: not all students want to stay on in education at 16. Peer groups are known to affect demand decision‐making and such affects are also known to be stronger for boys than for girls. Here we explicitly model the demand for post‐compulsory education as a function of peer groups. Our results suggest (1) boys’ intentions and realisations are influenced mainly by their male peers, and (2) girls’ intentions are influenced by their whole peer group while their female peer group influences their realisations. Policy targeted to increase participation rates should recognise these gender differences.
The flow of international students from a macro perspective: a network analysis

This paper provides a network analysis of the international flow of students among 210 countries and the factors determining the structure of this flow. Among these factors, bilateral hyperlink connections between countries and the number of telephone minutes (communication variables) are the most important predictors of the flow’s structure, followed by trade, the physical distance between countries, a common border between countries and a common language between two countries. The USA is by far the most central country in the flow of international students, followed by China, the UK, France, Germany, Australia and India. These results are discussed in light of World-System Theory. Future research should examine how the network of international student flows changes over time and consider additional factors to provide a better understanding of the network as an international system.
Australian IPv6 Readiness: Results of a National Survey

IPv6 is the replacement for the Internet's incumbent protocol, IPv4. Although exhaustion of the IPv4 address space is now imminent there has been no meaningful uptake of IPv6 since its standardisation in 1998. Data from a national survey of the top 1,000 IT user organisations in Australia are analysed, revealing that they have made little or no preparation for IPv6. This creates the potential for considerable disadvantage for Australian organisations. The author recommends that governments and regulatory bodies should consider regulatory or policy action to encourage the diffusion of IPv6. The author also recommends that enterprise organisations develop a longterm IPv6 strategy, implement IPv6 training programs, update their policy frameworks, and assess their IT assets and applications portfolios.
Do In-Training Evaluation Reports Deserve Their Bad Reputations? A Study of the Reliability and Predictive Ability of ITER Scores and Narrative Comments

Purpose Although scores on in-training evaluation reports (ITERs) are often criticized for poor reliability and validity, ITER comments may yield valuable information. The authors assessed across-rotation reliability of ITER scores in one internal medicine program, ability of ITER scores and comments to predict postgraduate year three (PGY3) performance, and reliability and incremental predictive validity of attendings’ analysis of written comments. Method Numeric and narrative data from the first two years of ITERs for one cohort of residents at the University of Toronto Faculty of Medicine (2009–2011) were assessed for reliability and predictive validity of third-year performance. Twenty-four faculty attendings rank-ordered comments (without scores) such that each resident was ranked by three faculty. Mean ITER scores and comment rankings were submitted to regression analyses; dependent variables were PGY3 ITER scores and program directors’ rankings. Results Reliabilities of ITER scores across nine rotations for 63 residents were 0.53 for both postgraduate year one (PGY1) and postgraduate year two (PGY2). Interrater reliabilities across three attendings’ rankings were 0.83 for PGY1 and 0.79 for PGY2. There were strong correlations between ITER scores and comments within each year (0.72 and 0.70). Regressions revealed that PGY1 and PGY2 ITER scores collectively explained 25% of variance in PGY3 scores and 46% of variance in PGY3 rankings. Comment rankings did not improve predictions. Conclusions ITER scores across multiple rotations showed decent reliability and predictive validity. Comment ranks did not add to the predictive ability, but correlation analyses suggest that trainee performance can be measured through these comments.
Multicentre cohort study of red blood cell use for revision hip arthroplasty and factors associated with greater risk of allogeneic blood transfusion.

BACKGROUND Revision hip arthroplasty (RHA) is associated with high rates of allogeneic blood transfusion (ABT). We aimed to determine factors associated with ABT in patients undergoing RHA in Scottish hospitals, with particular focus on perioperative cell salvage (PCS). METHODS A prospective observational cohort study of RHA procedures performed in 11 hospitals over 7 months was performed. We recorded predefined patient, surgery-related, and blood conservation factors that may influence perioperative ABT, together with postoperative haemoglobin (Hb) data and ABTs to day 7. We explored factors with strongest independent association with ABT during the perioperative period using multiple regression analysis. RESULTS Two hundred and ten cases were studied, of whom 58% received ABTs (mean 1.8 units), most of which (52%) occurred on the day of surgery. Eighty-eight (42%) patients received PCS, of whom 68 had red cells re-infused [mean re-infusion volume 312 ml (1st, 3rd quartile: 260, 363 ml)]. In unadjusted comparisons, patients receiving PCS had lower intraoperative (9% vs 40%) and total (55% vs 63%) exposure to ABTs. The mean (95% confidence interval) theatre blood loss was 1013 (899-1128) ml and was higher for combined femoral/acetabular revision and femoral revision than other categories. The mean postoperative Hb transfusion trigger was 80 g litre(-1). In multivariable models, preoperative Hb [odds ratio (OR) 0.35; P<0.001], patient weight (OR 0.96; P=0.004), operating theatre blood loss (OR 1.002; P<0.001), and re-infusion of PCS blood (OR 0.31; P=0.02) were independent predictors of ABT exposure. CONCLUSIONS PCS is an effective blood conservation strategy for RHA, especially for patients with preoperative anaemia, low body weight, or both.
Impact of Family Control/Influence on Stakeholders’ Perceptions of Benevolence

This article proposes a model explaining how family control/influence in an organization affects individual stakeholders’ perceptions of benevolence. The model suggests two effects. First, based on socioemotional wealth research, we propose that family control/influence positively affects stakeholders’ perceptions of benevolence through the benevolent behavior that the organization shows toward its stakeholders. However, this effect can be negatively influenced if the family’s socioemotional wealth goals in terms of “Family control and influence” and/or “Renewal of family bonds to the firm through dynastic succession” are at risk. Second, we argue that family control/influence, to the extent that it is perceivable to the stakeholder, influences stakeholders’ perceptions of benevolence through categorization processes. However, the impact of perceivable family control/influence on stakeholders’ perceptions of benevolence is not straightforward but instead hinges on a set of individual-level contingency factors of the stakeholder, such as stakeholders’ family business in-group membership, stakeholders’ secondhand category information, and stakeholders’ firsthand category information.
