Avoiding the Pitfall of Progress and Associated Perils of Evolutionary Education
Authors: Werth Alexander
Published: May 2012

People reflexively see all change as implying inevitably increasing progress and complexity. This expected directionality is especially observed in students’ views of living things, with some species envisioned as “higher” or more evolved. Students tend naturally to see all evolutionary change as adaptive, progressive, optimal, and teleological, with improvement achieved as needed or desired by organisms (if not as planned in advance). Following an extended outline of many interrelated ways, this basic yet unfortunately widespread and deep-seated misconception of evolutionary thinking ensnares students and hinders proper understanding of the actual pattern and process of evolution, a more useful pedagogical approach is presented. A strategy that involves eliciting preconceptions, engaging in numerous counterexamples, and continually reinforcing an alternative view is generally effective. This is best achieved by tackling the misconception of progress head-on, with an active learning model that forces students to come up with substitute explanations. Several examples of exercises and activities to combat the universal and automatically intuitive inclination toward teleological notions of progress are given, including analyses of paleontology, ecology, biochemistry, development, and systematics.
The Abundances of some Trace-elements in the First-ever Reported Sample of Spinifex-Textured Komatiite from Ghatti Hosahalli, Karnataka
Authors: Ramakrishnan M. , Mahabaleswar B. , Viswanathan S.
Published: May 2012

The paper reports wavelength-dispersive x-ray fluorescence spectrometric data on the abundances of Sc, V, Cr, Co, Ni, Cu, Zn, Rb, Sr, Y, Zr, Nb, Ba, Pb, and Th in the first-ever reported sample of spinifex-textured komatiite from India at Ghatti Hosahalli in Karnataka. With some exceptions, these abundances are similar to those reported for the spinifex-textured komatiite from the Barberton greenstone belt in South Africa. The values for some alteration-resistant element ratios — Ti/Zr, Ti/Y, Ti/Sc, Ti/V, Zr/Y, Zr/Sc, Sc/Y, V/Zr, and V/Sc — for chondrite and for spinifex-textured komatiites from Ghatti Hosahalli (India), Barberton (South Africa), Munro (Canada), and Yilgarn (Australia) reveal that, except for the Ti/Zr ratio for the Ghatti Hosahalli komatiite, the other ratios from the four terrains define a unique trend that is almost superimposed on the trend defined by these ratios for chondrite. This suggests that the processes of formation of komatiitic lavas from the four far-separated terrains were similar, and that, the source regions from which these lavas formed had a chondritic composition.
Tectono-Metamorphic and Geochronologic Studies from Sandmata Complex, Northwest Indian Shield: Implications on Exhumation of Late-Palaeoproterozoic Granulites in an Archaean-early Palaeoproterozoic Granite-Gneiss Terrane

Published: May 2012

Several bodies of granulites comprising charnockite, charno-enderbite, pelitic and calc-silicate rocks occur within an assemblage of granite gneiss/granitoid, amphibolite and metasediments (henceforth described as banded gneisses) in the central part of the Aravalli Mountains, northwestern India. The combined rock assemblage was thought to constitute an Archaean basement (BGC-II) onto which the successive Proterozoic cover rocks were deposited. Recent field studies reveal the occurrence of several bodies of late-Palaeoproterozoic (1725 and 1621 Ma) granulites within the banded gneisses, which locally show evidence of migmatization at c. 1900 Ma coeval with the Aravalli Orogeny. We report single zircon ‘evaporation’ ages together with information from LA-ICP-MS U-Pb zircon datings to confirm an Archaean (2905 – ca. 2500 Ma) age for the banded gneisses hosting the granulites. The new geochronological data, therefore, suggest a polycyclic evolution for the BGC-II terrane for which the new term Sandmata Complex is proposed. The zircon ages suggest that the different rock formations in the Sandmata Complex are neither entirely Palaeoproterozoic in age, as claimed in some studies nor are they exclusively Archaean as was initially thought. Apart from distinct differences in the age of rocks, tectono-metamorphic breaks are observed in the field between the Archaean banded gneisses and the Palaeoproterozoic granulites. Collating the data on granulite ages with the known tectono-stratigraphic framework of the Aravalli Mountains, we conclude that the evolution and exhumation of granulites in the Sandmata Complex occurred during a tectono-magmatic/metamorphic event, which cannot be linked to known orogenic cycles that shaped this ancient mountain belt. We present some field and geochronologic evidence to elucidate the exhumation history and tectonic emplacement of the late Palaeoproterozoic, high P-T granulites into the Archaean banded gneisses. The granulite-facies metamorphism has been correlated with the thermal perturbation during the asymmetric opening of Delhi basins at around 1700 Ma.

Published: May 2012

Recent developments in sensor technology have given an onset for studying the earth surface features based on the detailed spectroscopic observation of different rocks and minerals. The spectroscopic profiles of the rocks are always quite different than their constituent minerals however, the spectral profile of a rock can be broadly reconstituted from the spectral profile of each constituent minerals. Interpretation of rock spectra using the spectra of constituent minerals based on relative spectral matching can bring out interesting information on the rock. Present study is an effort toward this and it highlights how visible-near infrared-shortwave-infrared (VNIR-SWIR) rock spectroscopy acts as an useful tool for understanding the rock-mineralogy in indirect and rapid way. It has also been observed that spectral signatures of rocks; studied in present case, are related to spectral signatures of constituent minerals although absorption features of constituent mineral in the rock are also modified by the other minerals juxtaposed in the rock fabric. However, each rock of the study area has their significant absorption features, but many of the absorption signatures are closely spaced, as altered rock has significant absorption at 2305 nm whereas amphibolite has its important absorption signature in 2385 nm and metabasalt has its significant absorption at 2342 nm. Therefore spectral measurement of high spectral resolution with appreciable signal to noise ratio (SNR) only can detect rocks from each other based on the absorption signatures mentioned above (each of which is 10 to 20 nm apart from the other) and therefore spectroscopy of rock is an innovative technique to map rocks and minerals based on the spectral signatures.
Identification of Active Seismicity by Fractal Analysis for Understanding the Recent Geodynamics of Central Himalaya
Authors: Roy P. N. S. , Mondal S.K.
Published: May 2012

Seismicity along the Himalayan front is mostly attributed to the processes of collision between the Indian and the Eurasian plates resulting in the under-thrusting of the Indian Peninsula underneath the Himalaya. The dynamics of the region bears very complex components which require in-depth understanding. Here the overall rate of crustal shortening since ∼ 11 Ma is ∼ 21mm/yr, which is comparable to modern rate of under-thrusting of the northern Indian plate beneath the Himalaya. The region experienced a large number of great earthquakes for the last 100 – 120 years causing massive destruction. Here an attempt has been made to understand the seismicity pattern of the region using fractal correlation dimension and hence used for the detection of active seismicity. Some clusters of seismicity were found to be indicative of seismically very active zones. Such clusters may enlighten the understanding of recent complex dynamics of Himalayan zone.
Principal Component Analysis of Lithologic Variables in Early Permian Barakar Coal-Measures, Western Singrauli Gondwana Sub-Basin of Central India
Authors: Khan Z. A. , Tewari Ram Chandra
Published: May 2012

The quantitative relationships between lithological variables of Early Permian Barakar coal measures of western Singrauli Gondwana sub-basin are investigated using principal component analysis in an attempt to reveal simple relationships undetected by conventional quantitative methods. The results not only confirm and amplify those of the simple regression analysis described in Casshyap et.al. (1988), but are also interpreted in terms of evolution of coal swamps. If the total thickness of strata, total thickness of clastic sediments, total thickness of coal seams, number of sandstone beds, number of shale beds, number of coal seams and clastic ratio are considered, the first three components accounts for 80% of the total variance and the lithological variables generally fall into two groups. One group contains the first four variables, namely, total thickness of strata, total thickness of sandstone, total thickness of shale and total thickness of coal seams, all of which have basin-like regional patterns of sedimentation linked to net subsidence. The other group of variables, which are somewhat less closely related to net subsidence such as number of sandstone beds, number of shale beds and number of coal seam. The sand/shale ratio and clastic ratio are dependent on the other variables and seem to be unrelated to net subsidence. The principal component results, at best in geological term, may be explained by the to and fro lateral migration of a river channel across its flood plain coupled with a gradual isostatic adjustment of the basin floor in response to the weight of the sediments and differential subsidence through space and time.

Published: May 2012

Heavy mineral analysis was carried out for the beach and fore dune sediments along 60 transects of Nizampatnam-Lankavanidibba coastal area. The heavy mineral assemblage in this area with decreasing abundance of opaques (Ilmenite + magnetite, 47.67%), pyriboles (20.35%), garnets (3.66%), epidote (3.23%) and with less than 3.0% concentration of sillimanite, zircon, staurolite, kyanite, apatite, spinel, monazite, biotite, topaz, leucoxene and chlorite. The heavy mineral concentrations are high in the finer fractions i.e., +120 and +230 (ASTM) than the coarse fraction (+60) of sand. In the seven sectors, heavy mineral assemblage is same but their concentrations are different. The sectors nearer to the river mouth contain high concentration of high specific gravity heavy minerals (ilmenite and magnetite) than sectors away from the river mouth. The redistribution of heavy minerals is controlled by creek dynamics, longshore currents, size and specific gravity of the heavy minerals.
Coherent structures and dominant frequencies in a turbulent three-dimensional diffuser
Authors: Malm Johan , Schlatter Philipp , Henningson Dan S.
Published: May 2012

Dominant frequencies and coherent structures are investigated in a turbulent, three-dimensional and separated diffuser flow at$\mathit{Re}= 10\hspace{0.167em} 000$(based on bulk velocity and inflow-duct height), where mean flow characteristics were first studied experimentally by Cherry, Elkins and Eaton (Intl J. Heat Fluid Flow, vol. 29, 2008, pp. 803–811) and later numerically by Ohlssonet al. (J. Fluid Mech., vol. 650, 2010, pp. 307–318). Coherent structures are educed by proper orthogonal decomposition (POD) of the flow, which together with time probes located in the flow domain are used to extract frequency information. The present study shows that the flow contains multiple phenomena, well separated in frequency space. Dominant large-scale frequencies in a narrow band$\mathit{St}\equiv fh/ {u}_{b} \in [0. 0092, 0. 014] $(where$h$is the inflow-duct height and${u}_{b} $is the bulk velocity), yielding time periods${T}^{\ensuremath{\ast} } = T{u}_{b} / h\in [70, 110] $, are deduced from the time signal probes in the upper separated part of the diffuser. The associated structures identified by the POD are large streaks arising from a sinusoidal oscillating motion in the diffuser. Their individual contributions to the total kinetic energy, dominated by the mean flow, are, however, small. The reason for the oscillating movement in this low-frequency range is concluded to be the confinement of the flow in this particular geometric set-up in combination with the high Reynolds number and the large separated zone on the top diffuser wall. Based on this analysis, it is shown that the bulk of the streamwise root mean square (r.m.s.) value arises due to large-scale motion, which in turn can explain the appearance of two or more peaks in the streamwise r.m.s. value. The weak secondary flow present in the inflow duct is shown to survive into the diffuser, where it experiences an imbalance with respect to the upper expanding corners, thereby giving rise to the asymmetry of the mean separated region in the diffuser.

Published: May 2012

Lactating rats reinfected with Nippostrongylus brasiliensis fed low-crude protein (CP) foods show reduced lactational performance and less resistance to parasites compared with their high-CP counterparts. Here, we hypothesised that feeding high-CP foods deficient in specific essential amino acids (AA) would result in similar penalties. Second-parity lactating rats, immunised with 1600 N. brasiliensis infective larvae before mating, were fed foods with either 250 (high protein; HP) or 150 (low protein; LP) g CP/kg, or were HP deficient in either leucine (HP-Leu) or methionine (HP-Met). On day 1 of lactation, litter size was standardised at twelve pups. On day 2, dams were either reinfected with 1600 N. brasiliensis larvae or sham-infected with PBS. Dams and litters were weighed daily until either day 8 or 11, when worm burdens, and inflammatory cells and systemic levels of N. brasiliensis-specific Ig isotypes were assessed. Data from five out of sixteen HP-Met rats were omitted due to very high levels of food refusals from parturition onwards. Relative to feeding HP foods, feeding LP, HP-Met and HP-Leu foods reduced dam weight gain and, to a lesser extent, litter weight gain, and increased the number of worm eggs in the colon, indicative of a reduction in resistance to parasites. However, only feeding LP and HP-Leu foods resulted in increased worm numbers, while none of the feeding treatments affected systemic Ig, mast and goblet cells, and eosinophil numbers. The present results support the view that resistance to parasites during lactation may be sensitive to specific essential AA scarcity.

Inflammatory bowel diseases (IBD) are chronically relapsing inflammatory disorders of the intestine. Although some therapeutic agents, including steroids, are available for the treatment of IBD, these agents have limited use. Therefore, dietary supplements have emerged as possible interventions for IBD. Japanese honeysuckle flower, the flower of Lonicera japonica, is a well-known dietary supplement and has been used to prevent or treat various inflammatory diseases. In the present study, we investigated the effects of L. japonica on experimental murine colitis. Colitis was induced by 5 % dextran sulphate sodium (DSS) in Balb/c mice. The water extract of L. japonica (LJE) at doses of 20, 100 or 500 mg/kg was orally administered to mice twice per day for 7 d. Body weight, colon length and a histological damage score were assessed to determine the effects on colitis. Cytokine profiles were assessed to examine the effects on helper T (Th) cell-related immunological responses. In addition, CD4+CD25+Foxp3+T cells were analysed in vivo and in vitro for investigating the effects on regulatory T (Treg) cells. LJE showed dose-dependent inhibitory effects against colon shortening, weight loss and histological damage. LJE down-regulated IL-1β, TNF-α, interferon-γ, IL-6, IL-12 and IL-17. However, LJE did not show any significant effects on IL-10, IL-23, transforming growth factor-β1 and Treg cell populations. In conclusion, LJE showed protective effects against DSS-induced colitis via the Th1/Th17 pathway and not via Treg cell-related mechanisms.

Healthy diet and physical activity are associated with a lower cardiometabolic risk (CMR). Little is known about whether they interact to improve CMR. The purpose of the present study was to determine the synergistic associations of diet quality and physical activity energy expenditure (PAEE) on CMR factors. The present study was ana posteriorianalysis of two cross-sectional studies on 124 inactive non-diabetic postmenopausal women with a BMI ≥ 27 kg/m2. The following factors were measured: diet quality (assessed by the Canadian Healthy Eating Index (C-HEI) from a 3 d food record); PAEE (doubly labelled water); body composition (dual-energy X-ray absorptiometry, computed tomography scan); lipoprotein profile (total, HDL- and LDL-cholesterol (HDL-C and LDL-C), non-HDL-C, total cholesterol:HDL-C, TAG, apoA1, apoB, apoA1:apoB and LDL-C:apoB); insulin sensitivity (homeostasis model assessment of insulin resistance and hyperinsulinaemic–euglycaemic clamp); inflammatory markers (high-sensitivity C-reactive protein (hs-CRP), haptoglobin, orosomucoid, IL-6 and leucocyte count). The association of the interaction PAEE × C-HEI and CMR factors was evaluated by hierarchical regressions. Fat mass-adjusted ANCOVA determined the interaction between PAEE and the C-HEI. In hierarchical regressions, the interaction PAEE × C-HEI was a correlate of more favourable values of HDL-C, apoB, apoA1:apoB and LDL-C:apoB ratios, and hs-CRP, while only PAEE was a negative correlate of haptoglobin. Compared with those in the low-PAEE/low-C-HEI group, women in the high-PAEE/high-C-HEI group had 10 % higher HDL-C, 13 % lower apoB, 11 % larger LDL particles and 28 % lower hs-CRP concentrations (P< 0·05). PAEE and the C-HEI have a synergistic association with the CMR profile. These results support the integration of both diet quality and physical activity in the management of CMR.
The Ongoing Disaster
Authors: Dudden Alexis
Published: May 2012

On March 15, 2011, late at night at the Osaka train station, I met the first refugees from the earthquake that I would come to know. The family of four did not look like what I thought that people who were fleeing the horrendous images on television would. The mother, father, and two young daughters were neatly dressed, and their yellow lab was obediently packed into a crate that stood in the middle of their matching suitcases. Each wore a crisp, white mask. Much as I wanted to hear stories of what they had seen, I imagined that they did not want to talk. My son, however, zoomed a toy train over to their youngest girl, who was about six or seven; she happily raced it back. I motioned for him to stop and smiled at the mother, who acknowledged me from behind her mask as she brushed a hand across her forehead in exhaustion. “Are you OK?” I asked, not knowing how to avoid noticing that something appeared wrong. “Mmmm-hmmm.” “Are you traveling further tonight?” “Kanazawa.” “How terrible it all must be.” “We're from Fukushima,” she said. “We're fine. Our house is fine. It all looks fine, but we don't know what will happen, and the girls are so young.”
Articulating Regionalism through Popular Music: The Case ofNauchami Narayanain the Uttarakhand Himalayas
Authors: Fiol Stefan
Published: May 2012

As regionalism has become a politically and economically advantageous policy across much of Asia, vernacular popular music has concomitantly become an important arena for articulating and codifying shared regionalist sentiment. This article explores the reasons for the emergence of subnational regionalism within post-independence India, and its more recent resurgence since the 1990s, arguing that expansion and diversification of popular music (in combination with other media) industries have been central to these processes. Examining the case of the protest song “Nauchami Narayana” from the Uttarakhand Himalayas, the article then investigates how vernacular popular music can blend local signs of devotion and cultural identity in order to effect political change and articulate a space of regional belonging.
An Ever-contested Poem: TheClassic of Poetry's “Hanyi” and the Sino-Korean History Debate
Authors: Shim Jae-Hoon
Published: May 2012

Since 2003, the dispute over the history of the ancient kingdom of Koguryŏ (37bce, trad.-668ce), located in Manchuria and northern Korea, has been one of the hottest issues between China and Korea. The debate seems to have fueled a new nationalistic or Sinocentric historiography of the ancient Chinese northeast. A ninth century BCE poem called “Hanyi” in theClassic of Poetry[Shijing] has been the cause of a far older history dispute. Whereas Chinese scholars have generally understood Han as a Zhou feudal state ruled by a Ji-surnamed scion of the Zhou Dynasty (1045–256bce), most Korean scholars have linked the polity with Old Chosŏn (n.d.-108bce), the earliest known state in Korean history. However, by comparing the “Hanyi” with several bronze inscriptions with similar contents, this study seeks to re-read the “Hanyi” from a perspective that transcends the dichotomy of Chinese history versus Korean history.
Cognitions, behaviours and co-morbid psychiatric diagnoses in patients with chronic fatigue syndrome
Authors: Cella M. , White P. D. , Sharpe M. , Chalder T.
Published: May 2012

Background

Specific cognitions and behaviours are hypothesized to be important in maintaining chronic fatigue syndrome (CFS). Previous research has shown that a substantial proportion of CFS patients have co-morbid anxiety and/or depression. This study aims to measure the prevalence of specific cognitions and behaviours in patients with CFS and to determine their association with co-morbid anxiety or depression disorders.

Method

A total of 640 patients meeting Oxford criteria for CFS were recruited into a treatment trial (i.e. the PACE trial). Measures analysed were: the Cognitive Behavioural Response Questionnaire, the Chalder Fatigue Scale and the Work and Social Adjustment Scale. Anxiety and depression diagnoses were from the Structured Clinical Interview for DSM-IV. Multivariate analysis of variance was used to explore the associations between cognitive-behavioural factors in patients with and without co-morbid anxiety and/or depression.

Results

Of the total sample, 54% had a diagnosis of CFS and no depression or anxiety disorder, 14% had CFS and one anxiety disorder, 14% had CFS and depressive disorder and 18% had CFS and both depression and anxiety disorders. Cognitive and behavioural factors were associated with co-morbid diagnoses; however, some of the mean differences between groups were small. Beliefs about damage and symptom focussing were more frequent in patients with anxiety disorders while embarrassment and behavioural avoidance were more common in patients with depressive disorder.

Conclusions

Cognitions and behaviours hypothesized to perpetuate CFS differed in patients with concomitant depression and anxiety. Cognitive behavioural treatments should be tailored appropriately.
Protein flexibility in docking and surface mapping
Authors: Lexa Katrina W. , Carlson Heather A.
Published: May 2012

Structure-based drug design has become an essential tool for rapid lead discovery and optimization. As available structural information has increased, researchers have become increasingly aware of the importance of protein flexibility for accurate description of the native state. Typical protein–ligand docking efforts still rely on a single rigid receptor, which is an incomplete representation of potential binding conformations of the protein. These rigid docking efforts typically show the best performance rates between 50 and 75%, while fully flexible docking methods can enhance pose prediction up to 80–95%. This review examines the current toolbox for flexible protein–ligand docking and receptor surface mapping. Present limitations and possibilities for future development are discussed.
A quantitative assessment of students’ experiences of studying music: a Spanish perspective on the European credit transfer system (ECTS)
Authors: Esteve-Faubel José-María , Stephens Jonathan , Molina Valero Miguel Ángel
Published: May 2012

The purpose of this investigation is to evaluate whether or not the allocation of time proposed in the Music Study Guide, adapted from the European Higher Education Area (EHEA) guidelines, is consistent and adequate for students with minimal musical knowledge. The report takes into account the importance of students’ previous knowledge and the relation this has to the time and effort expended by students in acquiring appropriate knowledge and skills. This is related also to the adequacy of the course specification to meet the demands of university study and the labour market. Results show that those students who enrolled at university without any previous musical knowledge are likely to experience significant difficulty in the acquisition of certain musical and professional competences. This highlights a need to reinforce the music curriculum, or establish zero-level courses, in order to enable such students to succeed in the subject.
Singing in primary schools: case studies of good practice in whole class vocal tuition
Authors: Lamont Alexandra , Daubney Alison , Spruce Gary
Published: May 2012

Within the context of British initiatives in music education such as the Wider Opportunities programme in England and the recommendations of the Music Manifesto emphasising the importance of singing in primary schools, the current paper explores examples of good practice in whole-class vocal tuition. The research included seven different primary schools in England and combined observational methods and semi-structured interviews with musicians, teachers and headteachers. Results indicate a variety of successful approaches to promoting singing in primary schools. Essential motivators for developing singing include an enthusiastic staff member, a supportive headteacher and support from other school staff. Additional motivators include access to musical expertise within and beyond the school, and a singing leader with keyboard skills. Challenges to good practice centre on the issue of confidence and skill in singing from both teachers and pupils, individually and in groups, recognising and rewarding quality in singing, and the sustainability of externally funded initiatives as pupils move through their schooling and particularly from primary to secondary school. Good-quality support from specialists and external organisations can facilitate good practice in schools, but it seems to be important to integrate singing into children's wider musical learning and development within the curriculum, in the extended curriculum and beyond school in order to help sustain a lifelong interest in singing.
Death versus GDP! Decoding the Fatality Indicators on Work Safety Regulation in Post-Deng China
Authors: Chan Hon S. , Gao Jie
Published: May 2012

This article examines how Chinese reformers have used a set of “fatality indicators” to deal with the serious work safety situation in the past two decades. It argues that the system of fatality indicators is a prudent strategy to tackle the responsibility deficiencies in the previous work safety regulatory system and strengthen the central government's supervision over local safety management. The primary purpose of implementing the fatality indicators is to shift local officials' focus from a GDP-centred growth mode to a new mindset of achieving a balance between economic development and social stability in local governance. The article also indicates that the decline in work-related fatalities in recent years is evidence of the effectiveness of the fatality indicators. These achievements aside, however, the introduction of fatality indicators is closely associated with an increase in local officials' dishonest reporting of real death tolls and the fluctuation in very serious accidents.
Age and the Cost of Being Uyghurs in Ürümchi
Authors: Zang Xiaowei
Published: May 2012

This article asks: is the cost of being Uyghurs higher for young Uyghurs than for old Uyghurs in Ürümchi? I address this question with data from a survey of 2,947 people conducted in Ürümchi in 2005. The cost of being Uyghurs refers to the extent of economic inequality in the earnings of Han Chinese and Uyghurs. I develop three hypotheses on the effect of age on earnings differentials between Han Chinese and Uyghurs. Data analyses show that although young Uyghurs are better educated and earn more than old Uyghurs, they are more likely than old Uyghurs to suffer from being Uyghurs in Ürümchi. This finding has policy implications for the reduction of ethnic disparity in Xinjiang.

Une étude a montré que le programmeMon arthrite, je m’en charge!pouvait réduire la perception des limitations fonctionnelles des participants du groupe expérimental, réduire leur sentiment d’impuissance et améliorer leur perception de gestion de la maladie. La présente étude examine le maintien de ces bénéfices et le rôle du renforcement social sur ce maintien, huit mois après l’intervention. Les mesures ont été prises à quatre temps: 1) mesure de base (n=125); 2) deux mois plus tard, avant randomisation (pré-intervention); 3) deux mois post randomisation (post-intervention) et 4) dix mois après la randomisation (post-intervention 2) (n=80). Un devis expérimental randomisé a été utilisé pour comparer trois groupes: le groupe témoin, le groupe expérimental sans renforcement social et le groupe expérimental avec renforcement social post-intervention (i.e., téléphones mensuels par un bénévole). Les analyses multiniveaux ont révélé que les participants du groupe expérimental avec renforcement social ont continué à rapporter moins de limitations fonctionnelles (p= 0.05) et une meilleure perception de gestion de la maladie (p=0.07) que les participants du groupe expérimental sans renforcement social. Cette étude fournit des preuves préliminaires sur la valeur ajoutée des renforcements post-intervention pour maintenir les effets d’un programme d’autogestion chez des aînés frêles, confinés à domicile.
Mechanistic modeling of vertebrate spatial contrast sensitivity and acuity at low luminance
Authors: JARVIS JOHN R. , WATHES CHRISTOPHER M.
Published: May 2012

The validity of the Barten theoretical model for describing the vertebrate spatial contrast sensitivity function (CSF) and acuity at scotopic light levels has been examined. Although this model (which has its basis in signal modulation transfer theory) can successfully describe vertebrate CSF, and its relation to underlying visual neurophysiology at photopic light levels, significant discrepancies between theory and experimental data have been found at scotopic levels. It is shown that in order to describe scotopic CSF, the theory must be modified to account for important mechanistic changes, which occur as cone vision switches to rod vision. These changes are divided into photon management factors [changes in optical performance (for a dilated pupil), quantum efficiency, receptor sampling] and neural factors (changes in spatial integration area, neural noise, and lateral inhibition in the retina). Predictions of both scotopic CSF and acuity obtained from the modified theory were found to be in good agreement with experimental values obtained from the human, macaque, cat, and owl monkey. The last two species have rod densities particularly suited for scotopic conditions.
Macros that Work Together

Published: May 2012

Racket is a large language that is built mostly within itself. Unlike the usual approach taken by non-Lisp languages, the self-hosting of Racket is not a matter of bootstrapping one implementation through a previous implementation, but instead a matter of building a tower of languages and libraries via macros. The upper layers of the tower include a class system, a component system, pedagogic variants of Scheme, a statically typed dialect of Scheme, and more. The demands of this language-construction effort require a macro system that is substantially more expressive than previous macro systems. In particular, while conventional Scheme macro systems handle stand-alone syntactic forms adequately, they provide weak support for macros that share information or macros that use existing syntactic forms in new contexts. This paper describes and models features of the Racket macro system, including support for general compile-time bindings, sub-form expansion and analysis, and environment management. The presentation assumes a basic familiarity with Lisp-style macros, and it takes for granted the need for macros that respect lexical scope. The model, however, strips away the pattern and template system that is normally associated with Scheme macros, isolating a core that is simpler, can support pattern and template forms themselves as macros, and generalizes naturally to Racket's other extensions.
B-type natriuretic peptide: use and misuse in the older patient
Authors: Oxley K , Baxter J
Published: May 2012

B-type natriuretic peptide (BNP) and the inactive N-terminal fragment of the precursor (NT-proBNP) are hormones predominantly produced by the cardiac myocyte. It has been shown that very high levels of circulating natriuretic peptides correlate with a diagnosis of heart failure. In view of this, the current NICE, SIGN and European Society of Cardiology guidelines on heart failure recommend the measurement of natriuretic peptides as part of the diagnostic pathway for patients with suspected heart failure in primary care. Patients should be stratified according to results, with high-risk patients referred and reviewed by specialist services within 2 weeks. There has also been interest regarding the potential use of natriuretic peptides in disease surveillance, therapeutic monitoring and in-patient discharge planning. Consequently, it is a test that we will encounter with increasing frequency in clinical practice.

Heart failure is common in older people, hence geriatricians need to have an understanding of the implications of natriuretic peptide levels. The test can be affected by both physiological and pharmacological factors and this should be taken into consideration when interpreting results.
Le débit lent des Suisses romands: mythe ou réalité?
Authors: SCHWAB SANDRA , RACINE ISABELLE
Published: May 2012

Cette recherche vise à examiner empiriquement l'idée commune que les Suisses romands parlent lentement. Nous avons comparé, en parole lue, diverses variables temporelles produites par des locuteurs provenant d'une variété régionale française (Brunoy en Ile-de-France) et de deux variétés régionales suisses romandes (Neuchâtel et Nyon), et ce, en tenant compte de l’âge et du sexe des locuteurs. Les résultats montrent, d'une part, que, parmi les diverses variables temporelles, seule la vitesse d'articulation permet de distinguer les locuteurs des trois variétés régionales. D'autre part, ils soulignent le rôle différent, selon la variété régionale, que jouent l’âge et le sexe des locuteurs dans la production de la vitesse d'articulation.
Inclusive wealth: a tool for the United Nations
Authors: Duraiappah Anantha Kumar , Muñoz Pablo
Published: May 2012

The world's leaders, business leaders and the public at large are beginning to question, amidst the multiple social, environmental and economic crises, whether our present trajectory of economic growth is sustainable. We seem to force ourselves to believe that we can grow ourselves out of the multiple crises we face today. The notion of sustainable development and the call for going beyond just material wealth to gauge our wellbeing has long featured in much of the sustainable development, environmental and ecological economics literature. We are afraid the present preoccupation with the green economy will not provide the change we are looking for if we don't address the fundamental problem of what we are aiming to achieve and how we measure our progress towards achieving those goals. We fall into the trap many international agencies have made over the past six decades, where the means become the ends and the ends become an academic exercise (Chang, 2001).
BINDING MINIMUM WAGE AS AN EQUILIBRIUM SELECTION DEVICE
Authors: Beugnot Julie
Published: May 2012

This paper investigates the effects of a binding minimum wage in an economy which exhibits multiple unemployment equilibria. For this purpose, we develop a theoretical model based on the simple imperfectly competitive model of Manning [In Conference Papers, Economic Journal 100, 151–162 (1990)], in which we introduce labor heterogeneity and knowledge spillovers in the individual production technology. Then, using numerical simulations, we show that a binding minimum wage rules out the occurrence of an inefficient equilibrium. Last, we analyze the effects of a minimum wage increase on the labor market's outcomes.
Nuclear astrophysics: nucleosynthesis in the Universe
Authors: Lépine-Szily Alinka , Descouvemont Pierre
Published: May 2012

Nuclear astrophysics is a relatively young science; it is about half a century old. It is a multidisciplinary subject, since it combines nuclear physics with astrophysics and observations in astronomy. It also addresses fundamental issues in astrobiology through the formation of elements, in particular those required for a carbon-based life. In this paper, a rapid overview of nucleosynthesis is given, mainly from the point of view of nuclear physics. A short historical introduction is followed by the definition of the relevant nuclear parameters, such as nuclear reaction cross sections, astrophysical S-factors, the energy range defined by the Gamow peak and reaction rates. The different astrophysical scenarios that are the sites of nucleosynthesis, and different processes, cycles and chains that are responsible for the building of complex nuclei from the elementary hydrogen nuclei are then briefly described.
Diasporic Dialogues in Mid-Century New York: Stefan Wolpe, George Russell, Hannah Arendt, and the Historiography of Displacement
Authors: COHEN BRIGID
Published: May 2012

This article explores mid-century New York intellectual scenes mediated by the avant-garde émigré composer Stefan Wolpe (1902–72), with special emphasis on Wolpe's interactions with jazz composer George Russell (1923–2009) and political philosopher Hannah Arendt (1906–75). Cross-disciplinary communities set the stage for these encounters: Wolpe and Russell met in the post-bop circles that clustered in Gil Evans's basement apartment, while Wolpe encountered Arendt at the Eighth Street Artists’ Club, the hotbed of Abstract Expressionism. Wolpe's exchanges with Arendt and Russell, long unacknowledged, may initially seem unrelated. Yet each figure shared a series of “cosmopolitan” commitments. They valued artistic communities as spaces for salutary acts of cultural boundary crossing, and they tended to see forms of self-representation in the arts as a way to respond to the dehumanizing political disasters of the century. Wolpe and Arendt focused on questions of human plurality in the wake of their forced displacements as German-Jewish émigrés, whereas Russell confronted dilemmas of difference as an African American migrant from southern Ohio in New York. Bringing together interpretive readings of music with interview- and archive-based research, this article works toward a historiography of aesthetic modernism that recognizes migration as formative rather than incidental to its community bonds, ethical aspirations, and creative projects.
Jazzing the Classics: Race, Modernism, and the Career of Arranger Chappie Willet
Authors: WRIGGLE JOHN
Published: May 2012

The American popular music tradition of “jazzing the classics” has long stood at the intersection of discourses on high and low culture, commercialism, and jazz authenticity. Dance band arrangers during the 1930s and 1940s frequently evoked, parodied, or straddled these cultural debates through their manipulations of European classical repertoire. This article examines Swing Era arranging strategies in the context of prevailing racial essentialisms, conceptions of modernism, and notions of technical virtuosity. The legacy of African American freelance arranger Chappie Willet, and his arrangement of Beethoven's Piano Sonata, op. 13 (“Pathétique”) for the black dance band of Jimmie Lunceford, suggests that an account of the biography and artistic voice of the arranger is critical to understanding the motivations behind these hybrid musical works.
Reminiscence, Reflections, and Resonance: The Just Intonation Resophonic Guitar and Lou Harrison'sScenes from Nek Chand
Authors: FIORE GIACOMO
Published: May 2012

Upon accepting a commission for a solo guitar piece from the 2002 Open Minds Music Festival in San Francisco, Lou Harrison decided to writeScenes from Nek Chandfor a unique instrument: a resonator guitar refretted in just intonation. Harrison's last completed work draws inspiration from the sound of Hawaiian music that the composer remembered hearing in his youth, as well as from the artwork populating Nek Chand's Rock Garden of Chandigarh, India.

Based on archival research, oral histories, and the author's insights as a performer of contemporary music, this article examines the piece's inception, outlining the organological evolution of resophonic guitars and their relationship to Hawaiian music. It addresses the practical and aesthetic implications of the composer's choice of tuning, and examines the work of additional artists, such as Terry Riley and Larry Polansky, who have contributed to the growing repertoire for the just intonation resophonic guitar.
THE GENETIC VERSUS THE AXIOMATIC METHOD: RESPONDING TO FEFERMAN 1977
Authors: LANDRY ELAINE
Published: May 2012

Feferman (1977) argues that category theory cannot stand on its own as a structuralist foundation for mathematics: he claims that, because the notions of operation and collection are both epistemically and logically prior, we require a background theory of operations and collections. Recently [2011], I have argued that in rationally reconstructing Hilbert’s organizational use of the axiomatic method, we can construct an algebraic version of category-theoretic structuralism. That is, in reply to Shapiro (2005), we can be structuralists all the way down; we do not have to appeal to some background theory to guarantee the truth of our axioms. In this paper, I again turn to Hilbert; I borrow his (Hilbert, 1900a) distinction between the genetic method and the axiomatic method to argue that even if the genetic method requires the notions of operation and collection, the axiomatic method does not. Even if the genetic method is in some sense epistemically or logically prior, the axiomatic method stands alone. Thus, if the claim that category theory can act as a structuralist foundation for mathematics arises from the organizational use of the axiomatic method, then it does not depend on the prior notions of operation or collection, and so we can be structuralists all the way up.
Sportaktivität als Stresspuffer
Authors: Klaperski Sandra , Seelig Harald , Fuchs Reinhard
Published: May 2012

Zusammenfassung: Die Rolle des Sports als Strategie der Stressregulation ist noch wenig systematisch erforscht. Im vorliegenden Beitrag wird die sog. „Stresspuffer-Hypothese der Sportaktivität“ genauer geprüft. Sie besagt, dass Sportaktivität die negativen Auswirkungen von Stress auf die Gesundheit „abzupuffern“ vermag. Bis heute ist diese Hypothese noch nicht überzeugend empirisch belegt, vor allem mangelt es an längsschnittlicher und experimenteller Evidenz. In der vorliegenden Studie wird die Stresspuffer-Hypothese sowohl quer- als auch längsschnittlich überprüft: N = 427 Angestellte machten an zwei Messzeitpunkten im Abstand von zehn Monaten Angaben zu ihrer seelischen Gesundheit, ihrem arbeitsbedingten Stresserleben und ihrer Sportaktivität. Die Ergebnisse bestätigen den Stresspuffereffekt auf der Ebene der Querschnittsanalysen – bei Betrachtung des aktuellen Stresserlebens und des aktuellen Sporttreibens – nur teilweise, auf der Ebene der Längsschnittanalysen – bei Betrachtung des chronischen Stresserlebens und des chronischen Sporttreibens – dagegen in vollem Umfang. Die Befunde deuten darauf hin, dass das habituelle Sportverhalten insbesondere bei zeitlich andauernden Stressbedingungen seine gesundheitsprotektive Wirkung zu entfalten vermag.
Zur Anwendung der Elektroenzephalographie in der Sportpsychologie
Authors: Doppelmayr Michael , Amesberger Günter
Published: May 2012

Zusammenfassung: Das Elektroenzephalogramm (EEG) ist ein geeignetes Instrument, um diejenigen bioelektrischen Vorgänge zu untersuchen, die kognitiven Prozessen oder emotionalen Zuständen zugrunde liegen, welche fundamentale Prozesse im Sport darstellen. Ziel dieses Artikels ist es, die methodischen Möglichkeiten der Elektroenzephalographie in bewegungs- und sportwissenschaftlichen Studien zu beleuchten, einen Überblick über bisherige Befunde zu geben und die Verwendung des EEGs kritisch zu bewerten. Nach einer einführenden Darstellung der Grundlagen des EEGs und der wichtigsten Analysemöglichkeiten, werden drei Gruppen von Studien diskutiert, die sich mit den EEG Korrelaten 1. grundlegende Aspekte von Bewegung und Bewegungslernen, 2. aufmerksamkeitsspezifische Veränderungen während der Bewegung und 3. affektive Veränderungen im Zusammenhang mit sportlicher Bewegung beschäftigen. Es wird die Relevanz der Elektroenzephalographie aufgezeigt und abschließend auch auf die Limitationen dieses Zuganges eingegangen.
