Intelligence
Authors: Sternberg Robert J. 
Published: July 2012

AbstractIntelligence is the ability to learn from past experience and, in general, to adapt to, shape, and select environments. Aspects of intelligence are measured by standardized tests of intelligence. Average raw (number‐correct) scores on such tests vary across the life span and also across generations, as well as across ethnic and socioeconomic groups. Intelligence can be understood in part in terms of the biology of the brain—especially with regard to the functioning in the prefrontal cortex. Measured values correlate with brain size, at least within humans. The heritability coefficient (ratio of genetic to phenotypic variation) is between 0.4 and 0.8. But genes always express themselves through environment. Heritability varies as a function of a number of factors, including socioeconomic status and range of environments. Racial‐group differences in measured intelligence have been reported, but race is a socially constructed rather than biological variable. As a result, these differences are difficult to interpret. Different cultures have different conceptions of the nature of intelligence, and also require different skills in order to express intelligence in the environment.

Published: July 2012

AbstractBackgroundLaparoscopic cholecystectomy (LC) performed for acute cholecystitis (AC) is usually advised within 72 h of symptom onset. It can be difficult to accommodate all these patients within 72 h. LC beyond this early phase potentially increases the chances of LC‐related complications. The aim of this study was to evaluate the outcomes of LC both within and beyond 72 h of presentation during the emergency admission.MethodsA retrospective clinical study was performed from February 2004 to December 2009. A total of 133 patients underwent LC for AC during the emergency admission according to the protocol: 34 patients underwent early LC (ELC) (i.e., operation within 72 h of symptom onset) and 99 underwent late LC (LLC) (i.e., operation beyond 72 h of symptom onset). Pathologic type of cholecystitis, duration of the procedure, conversion rate, complications, length of hospital stay (LOS), and total charges were compared between the two groups.ResultsPatients undergoing ELC experienced a significantly shorter operating time (44.1 ± 5.32 vs. 66.4 ± 3.05 min, p < 0.01). Most of the AC (95/133, 71 %) was pathologically simple cholecystitis. There was no significant difference regarding wound infection rates [1/34 (2.94 %) vs. 2/99 (2.02 %), p > 0.05] or postoperative hospital stay (6.50 ± 1.31 vs. 6.67 ± 0.73, p > 0.05) between groups. There were no conversions to open cholecystectomy, no biliary tract injury or biliary leak, no other complications, and no 30‐day readmission rates in either group. ELC was less costly than LLC (6,692 ± 794 vs. 8,378 ± 802 RMB, p < 0.05).ConclusionsBoth ELC and LLC are safe for treating of AC, but the operative difficulty of LLC is greater. ELC is superior to LLC as it tends to shorten the total LOS and is less expensive.
A proactive personalised mobile recommendation system using analytic hierarchy process and Bayesian network

Published: July 2012

Abstract
With the growth, ready availability and affordability of wireless technologies, proactive context-aware recommendations are a potential solution to overcome the information overload and the common limitations of mobile devices (inconvenience of data input and Internet browsing). The automatic provision of just-in-time information or recommendations tailored to each user’s needs/preferences contextualised from the user’s activities, location, usage patterns, time, and connectivity may not only facilitate access to information but also remove barriers to the adoption of current and future services on mobile devices. This paper describes a hybrid P2P context-aware framework called JHPeer which supports a variety of context-aware applications in mobile environments. Any context-aware information services such as recommendation services could use the collected and shared contextual information in JHPeer network. An analytic hierarchy process based multi-criteria ranking (AHP-MCR) approach has been developed and used to rate recommendations in a variety of domains. The weights of the contexts criteria can be assigned by the user or automatically adjusted via individual-based and/or group-based assignment. Additionally, a Bayesian network algorithm is applied to solve the cold-start problem in recommendation systems. The paper also proposes a strategy for using Bayesian networks for recommendation services. A news recommendation application has been implemented on the developed JHPeer framework, which proactively pushes relevant news based on the users’ contextual information. Evaluation studies show that the system can push relevant recommendations to mobile users appropriately.
The Changing Impact of Family Size on Adolescents’ Schooling: Assessing the Exogenous Variation in Fertility Using Twins in Brazil
Authors: Marteleto Letícia J. , de Souza Laetícia R. 
Published: July 2012

Abstract
Researchers have long been interested in the influence of family size on children’s educational outcomes. Simply put, theories have suggested that resources are diluted within families that have more children. Although the empirical literature on developed countries has generally confirmed the theoretical prediction that family size is negatively related to children’s education, studies focusing on developing societies have reported heterogeneity in this association. Recent studies addressing the endogeneity between family size and children’s education have also cast doubt on the homogeneity of the negative role of family size on children’s education. The goal of this study is to examine the causal effect of family size on children’s education in Brazil over a 30-year period marked by important social and demographic change, and across extremely different regions within the country. We implement a twin birth instrumental variable approach to the nationally representative 1977–2009 PNAD data. Our results suggest an effect of family size on education that is not uniform throughout a period of significant social, economic, and demographic change. Rather, the causal effect of family size on adolescents’ schooling resembles a gradient that ranges from positive to no effect, trending to negative.
The Evolution of Notational Innovations from the Mobile Score to the Screen Score
Authors: Vickery Lindsay 
Published: July 2012

This article examines the evolution of music notational practices from avant-garde-era experiments in ‘mobility’ to the advent of the digital ‘screen score’. It considers the varied goals of the composers who initiated these developments and the dissonance between these goals and the practical possibilities actually afforded by the paper score.The advent of graphical computing is charted along with the consequent expansion of possibilities afforded by screening the score from a platform that also provides the potential for performer coordination, sound synthesis and transformation. The performative, interactive and formal implications of these possibilities are considered.

Published: July 2012

Abstract
From 2006 to 2009, we tagged and released 22,202 fish with T-bar anchor tags valued at US$0 to $200 if returned. Our intent was to assess angler tag reporting rates in Idaho and to determine whether reporting rates declined over time or differed between species. A total of 4,643 tags were reported by anglers. Assuming a reporting rate of 100% for $200 tags, weighted mean reporting rates were 54.2% for $0 tags, 69.7% for $10 tags, 91.7% for $50 tags, and 98.9% for $100 tags. By combining $100 and $200 as high-reward tags to increase sample size, nonreward tag-reporting rate was 54.5%. Tag reporting rates varied between groups of species, being highest for harvest-oriented species, both coolwater and warmwater, such as walleye Sander vitreus ($0 = 68.3%), yellow perch Perca flavescens (58.5%), and crappie Pomoxis spp. (59.7%), and lowest for largemouth bass Micropterus salmoides (39.2%). There was little variation in tag-reporting rates over time, weighted means being 53, 56, 50, and 56% from 2006 to 2009, but reporting rate did appear to decline for some species (most notably crappies). There was some evidence of a slight violation of the assumption of independence in tag-reporting, indicated by nonreward tag-reporting rates being marginally higher for anglers reporting both nonreward and reward tags than for those reporting only one or the other (signifying possible batch-reporting of tags). No batch-reporting was evident from differences in reporting rates for households reporting multiple tags compared with those reporting only one tag. Our results suggest that anglers in Idaho reported over half the nonreward tags they encountered, but rates appeared to vary among species, and this knowledge is being used to estimate angler exploitation across Idaho.

Published: July 2012

Abstract
Motivation: Next-generation sequence analysis has become an important task both in laboratory and clinical settings. A key stage in the majority sequence analysis workflows, such as resequencing, is the alignment of genomic reads to a reference genome. The accurate alignment of reads with large indels is a computationally challenging task for researchers.
Results: We introduce SeqAlto as a new algorithm for read alignment. For reads longer than or equal to 100 bp, SeqAlto is up to 10 × faster than existing algorithms, while retaining high accuracy and the ability to align reads with large (up to 50 bp) indels. This improvement in efficiency is particularly important in the analysis of future sequencing data where the number of reads approaches many billions. Furthermore, SeqAlto uses less than 8 GB of memory to align against the human genome. SeqAlto is benchmarked against several existing tools with both real and simulated data.

Regulating the Employment Relationship in Professional Team Sports
Authors: O’LEARY LEANNE 
Published: July 2012

ABSTRACT
A sporting code’s governing body is a private association of members that frequently exercises monopoly power in the sport over which it presides. In a professional team sports competition, a sporting code’s governing body may prescribe standard terms and conditions of employment, organise the competition and adopt regulatory measures which directly or indirectly affect the employment interests of players. In most relevant circumstances, a sporting code’s governing body is not obliged to inform, consult with or seek the agreement of players prior to the implementation of a regulatory measure that directly or indirectly affects a player’s employment. Strengthening the regulation of professional sport through competition law could balance the employment interests of players with the commercial and regulatory interests in a professional sports competition. Establishing a direct employment relationship between players and the sporting code’s governing body would also assist.
First Report of Meloidogyne enterolobii Infecting Euphorbia punicea in Florida
Authors: Han H. , Brito J. A. , Dickson D. W. 
Published: July 2012

Euphorbia punicea (Euphorbiaceae), commonly known as Jamaican poinsettia, is an evergreen shrub with dark green leaves and flashy red bracts. Bracts are sharply contrasted by rosettes of dark green leaves and can be observed in early summer, spring, fall, and winter. This shrub, native to Jamaica, is suitable in southern climates both in the landscape and as a seasonal patio container plant. Outdoors, the plants can reach as high as 5 meters. In January of 2012, E. punicea plants growing in an ornamental nursery in Dade Co., Florida, were observed with stunted growth and yellowing leaves. Root systems of affected plants were collected and sent to the Florida Department of Agriculture and Consumer Services, Nematology Laboratory, Gainesville, FL. Root systems showing symptoms of root-knot nematode infections were heavily galled and had already started rotting. Galls were observed in the primary, secondary, and tertiary roots. Species identification was initially performed using morphology and morphometrics. The morphology of the perineal patterns and measurements of selected characters of the second-stage juveniles fit those of the original description for M. enterolobii (3). The nematode species identification was confirmed using PCR to amplify mtDNA with the C2F3/1108 primer set (1) and a species-specific SCAR primer set, MK7-F/MK7-R (2). The PCR products were approximately 700 bp for mtDNA and approximately 520 bp for the SCAR, which were identical to those previously reported for M. enterolobii (1, 2). Sanitation practices should be implemented to avoid the spread of this nematode species within and between ornamental nurseries. Planting material should be produced in media free of this pathogen to avoid its introduction into uninfested nurseries and landscape areas. M. enterolobii has a wide host range, including cover and vegetable crops, fruit trees, herbs, and ornamental and weed plants. To our knowledge, this is the first report worldwide of E. punicea as a host of M. enterolobii. References: (1) T. O. Powers et al. J. Nematol. 37:226, 2005. (2) M. S. Tigano et al.

Authors: Campbell J. P. , Mackenzie M. J. , Yentis S. M. , Sooranna S. R. , Johnson M. R. 
Published: July 2012

SummaryHaemorrhage remains an important cause of maternal mortality worldwide. Cell salvage carries a theoretical risk of amniotic fluid embolus syndrome and is too expensive for use in many parts of the world. To explore cheaper options, we investigated whether a leucocyte depletion filter alone removes components of pure amniotic fluid. Amniotic fluid was collected from 10 women during elective caesarean section and passed through a LeukoGuard® RS filter. Pre‐ and post‐filtration samples were compared in the laboratory. Lamellar bodies and fetal squames were almost completely removed (filtration efficacy 96.6% and 99.9%, respectively; p < 0.0001 and <0.0004), and hair was completely removed (p = 0.002). Filtration had no effect on concentrations of α‐fetoprotein, tissue factor or endothelin‐1, or on the presence of meconium or vernix. Additional work is required to evaluate whether cell salvage using filtration alone may be useful in maternal haemorrhage in the developing world.

AimTo assess the pharmacokinetics, pharmacodynamics, safety and tolerability of the 5‐lipoxygenase‐activating protein inhibitor, GSK2190915, after oral dosing in two independent phase I studies, one in Western European and one in Japanese subjects, utilizing different formulations.MethodWestern European subjects received single (50–1000 mg) or multiple (10–450 mg) oral doses of GSK2190915 or placebo in a dose‐escalating manner. Japanese subjects received three of four GSK2190915 doses (10–200 mg) plus placebo once in a four period crossover design. Blood samples were collected for GSK2190915 concentrations and blood and urine were collected to measure leukotriene B4 and leukotriene E4, respectively, as pharmacodynamic markers of drug activity.ResultsThere was no clear difference in adverse events between placebo and active drug‐treated subjects in either study. Maximum plasma concentrations of GSK2190915 and area under the curve increased in a dose‐related manner and mean half‐life values ranged from 16–34 h. Dose‐dependent inhibition of blood leukotriene B4 production was observed and near complete inhibition of urinary leukotriene E4 excretion was shown at all doses except the lowest dose. The EC50 values for inhibition of LTB4 were 85 nm and 89 nm in the Western European and Japanese studies, respectively.ConclusionGSK2190915 is well‐tolerated with pharmacokinetics and pharmacodynamics in Western European and Japanese subjects that support once daily dosing for 24 h inhibition of leukotrienes. Doses of ≥50 mg show near complete inhibition of urinary leukotriene E4 at 24 h post‐dose, whereas doses of ≥150 mg are required for 24 h inhibition of blood LTB4.
Temporal variability in the spatial and environmental determinants of functional metacommunity organization – stream fish in a human‐modified landscape
Authors: ERŐS T. , SÁLY P. , TAKÁCS P. , SPECZIÁR A. , BÍRÓ P. 
Published: July 2012

Summary1. Quantifying the relative importance of environmental filtering versus regional spatial structuring has become an intensively studied area in the context of metacommunity ecology. However, most studies have evaluated the role of environmental and spatial processes using taxonomic data sets of single snapshot surveys.2. Here, we examined temporal changes in patterns and possible processes behind the functional metacommunity organization of stream fishes in a human‐modified landscape. Specifically, we (i) studied general changes in the functional composition of fish assemblages among 40 wadeable stream sites during a 3‐year study period in the catchment area of Lake Balaton, Hungary, (ii) quantified the relative importance of spatial and environmental factors as determinants of metacommunity structure and (iii) examined temporal variability in the relative role of spatial and environmental processes for this metacommunity.3. Partial triadic analysis showed that assemblages could be effectively ordered along a functional gradient from invertebrate consuming species dominated by the opportunistic life‐history strategy, to assemblages with a diverse array of functional attributes. The analysis also revealed that functional fish assemblage structure was moderately stable among the sites between the sampling periods.4. Despite moderate stability, variance partitioning using redundancy analyses (RDA) showed considerable temporal variability in the contribution of environmental and spatial factors to this pattern. The analyses also showed that environmental variables were, in general, more important than spatial ones in determining metacommunity structure. Of these, natural environmental variables (e.g. altitude, velocity) proved to be more influential than human‐related effects (e.g. pond area, % inhabited area above the site, nutrient enrichment), even in this landscape with relatively low variation in altitude and stream size.5. Pond area was, however, the most important human stressor variable that was positively associated with the abundance of non‐native species with diverse functional attributes. The temporal variability in the relative importance of environmental and spatial factors was probably shaped by the release of non‐native fish from fish ponds to the stream system during flood events.6. To conclude, both spatial processes and environmental control shape the functional metacommunity organization of stream fish assemblages in human‐modified landscapes, but their importance can vary in time. We argue, therefore, that metacommunity studies should better consider temporal variability in the ecological mechanisms (e.g. dispersal limitation, species sorting) that determine the dynamics of landscape‐level community organization.
Re‐building brown trout populations in dredged boreal forest streams: in‐stream restoration combined with stocking of young trout
Authors: LUHTA PIRKKO‐LIISA , HUUSKO ARI , LOUHI PAULIINA 
Published: July 2012

Summary1. Rivers in boreal forested areas were often dredged to facilitate the transport of timber resulting in channels with simplified bed structure and flow fields and reduced habitat suitability for stream organisms, especially lotic fishes. Currently, many streams are being restored to improve their physical habitat, by replacing boulders and gravel and removing constraining embankments. The most compelling justification behind stream restoration of former floatways has been the enhancement of native fish populations, specifically salmonids.2. We examined the success of a stream management programme aimed at re‐building diminished brown trout (Salmo trutta) populations by monitoring densities of young‐of‐year and older trout in 18 managed and three reference streams during 2000–2005. Rehabilitation included in‐stream restoration combined with a 5‐year post‐restoration period of stocking young brown trout. Our space‐for‐time substitution design comprised four pre‐management, four under‐management, 10 post‐management and three reference streams.3. Densities of young‐of‐year brown trout, indicating population establishment, were significantly higher in post‐ compared with pre‐management streams. However, density of young‐of‐year brown trout in post‐management streams was significantly lower compared with near‐pristine reference streams. Furthermore, success of managed brown trout population re‐building varied, indicating stream‐specific responses to management measures. Density of burbot (Lota lota), a native generalist predator, was associated with low recruitment of brown trout.4. Stream‐specific responses imply that rehabilitation of brown trout populations cannot be precisely predicted thereby limiting application. Our findings support the importance of adaptive stream restoration and management, with focus on identifying factor(s) limiting the establishment of target fish populations.
