Evaluation of Actiheart and a 7 d activity diary for estimating free-living total and activity energy expenditure using criterion methods in 1·5- and 3-year-old children
Authors: Henriksson Hanna , Forsum Elisabet , Löf Marie 
Published: February 2014

Accurate and easy-to-use methods to assess free-living energy expenditure in response to physical activity in young children are scarce. In the present study, we evaluated the capacity of (1) 4 d recordings obtained using the Actiheart (mean heart rate (mHR) and mean activity counts (mAC)) to provide assessments of total energy expenditure (TEE) and activity energy expenditure (AEE) and (2) a 7 d activity diary to provide assessments of physical activity levels (PAL) using three sets of metabolic equivalent (MET) values (PALTorun, PALAdolphand PALAinsworth) in forty-four and thirty-one healthy Swedish children aged 1·5 and 3 years, respectively. Reference TEE, PALrefand AEE were measured using criterion methods, i.e. the doubly labelled water method and indirect calorimetry. At 1·5 years of age, mHR explained 8 % (P= 0·006) of the variation in TEE above that explained by fat mass and fat-free mass. At 3 years of age, mHR and mAC explained 8 (P= 0·004) and 6 (P= 0·03) % of the variation in TEE and AEE, respectively, above that explained by fat mass and fat-free mass. At 1·5 and 3 years of age, average PALAinsworthvalues were 1·44 and 1·59, respectively, and not significantly different from PALrefvalues (1·39 and 1·61, respectively). By contrast, average PALTorun(1·5 and 3 years) and PALAdolph(3 years) values were lower (P< 0·05) than the corresponding PALrefvalues. In conclusion, at both ages, Actiheart recordings explained a small but significant fraction of free-living energy expenditure above that explained by body composition variables, and our activity diary produced mean PAL values in agreement with reference values when using MET values published by Ainsworth.
Where's the ‘Faith’ in ‘Faith-Based’ Organisations? The Evolution and Practice of Faith-Based Homelessness Services in the UK
Authors: JOHNSEN SARAH 
Published: February 2014

AbstractDrawing upon a qualitative exploration of the role of faith-based organisations (FBOs) in service provision for homeless people in the UK, this paper examines the ways in which the ‘faith’ in ‘faith-based’ services is articulated and experienced ‘on the ground’. It demonstrates that the ‘F’ in FBO is expressed in a myriad of nuanced ways, and that the strength of ‘coupling’ between many welfare agencies and organised religion has diminished over time such that some projects’ faith affiliation or heritage is now evident in palimpsest only. Homeless people do in fact often find it difficult to discern tangible differences between avowedly ‘faith-based’ and ‘secular’ projects, given a blurring of boundaries between the religious and the secular. These findings problematise FBO typologies, and highlight the complexity and fluidity of the very concept of ‘FBO’ itself. Certainly, they suggest that the differences between faith-based and secular provision should not be exaggerated, whilst recognising the importance of faith to the motivations of many service providers and the potential value of the (optional) ‘spiritual’ support offered by most FBOs.
Is ego depletion too incredible? Evidence for the overestimation of the depletion effect
Authors: Carter Evan C. , McCullough Michael E. 
Published: February 2014

AbstractThe depletion effect, a decreased capacity for self-control following previous acts of self-control, is thought to result from a lack of necessary psychological/physical resources (i.e., “ego depletion”). Kurzban et al. present an alternative explanation for depletion; but based on statistical techniques that evaluate and adjust for publication bias, we question whether depletion is a real phenomenon in need of explanation.
Copernicus's Development in Context: Politics, Astrology, Cosmology and a Prince-Bishopric
Authors: Blumenthal Geoffrey 
Published: February 2014

ArgumentDuring the two decades before the turning point in Copernicus's personal and scientific development in 1510, he had experience of political activity which has been largely ignored by the existing Copernicus literature but part of which is reconstructed in outline in this paper. Given the close linkage between politics and astrology, Copernicus's likely reaction to astrology is re-examined here. This reconstruction also suggests that the turning point in 1510, when Copernicus left his post as secretary to his uncle Lucas Watzenrode the prince-bishop of Warmia, was not only linked to Copernicus's first version of his heliocentric theory in theCommentariolus, but also to major political setbacks being experienced by Watzenrode during these years, and with the publication of Copernicus's translation of theLettersof Theophylactus Simocatta. Some of these considerations contribute to maintaining the view that Copernicus and his work were in several respects exceptional.
The Portuguese Astronomer Melo e Simas (1870–1934): Republican Ideals and Popularization of Science
Authors: Simões Ana , Carolino Luís Miguel 
Published: February 2014

ArgumentThis paper analyses a process of co-construction of knowledge and its multiple forms of communication in a country of the European periphery in the early twentieth century. It focuses on Lieutenant Manuel Soares de Melo e Simas, a politically engaged Portuguese astronomer, who moved from amateur to professional during the political transition from the monarchy to the republic. Melo e Simas paralleled his professional career in continuous activity of communicating science to the public in the context of republicanism in a double way, by responding to the agenda of republicanism and by playing an active role in shaping it. He aimed at educating lay audiences in the various ways of astronomy, and he reached out to as many people as possible by exploring a multitude of communication channels, from lectures to articles in newspapers and journals. Voiced often within newly created republican institutions, the praxis and the ideas of Melo e Simas helped to mold the new republican scientific ethos. By going beyond mere emphasis on scientism and positivism, usually taken to be the defining characteristics of the new republican ethos, this paper argues that science and the specificities of its multiple forms of communication were central to the way Melo e Simas shaped the republican ideology. Furthermore, popularization of science was used to legitimize the status of professional scientists at the same time that it helped reinforce their institutional setting, still to be negotiated in the forthcoming decades through a complex process which deserves further historical analysis.
Mobility and Migration of Spanish Mathematicians during the Years around the Spanish Civil War and World War II
Authors: Pacheco José M. 
Published: February 2014

ArgumentThis paper considers some aspects of the reception and development of contemporary mathematics in Spain during the first half of the twentieth century, more specifically between 1910 and 1950. It analyzes the possible influence of scientists’ mobility in the adoption of newer views or theories. A short overview of key points of the social and scientific background in nineteenth-century Spain locates the expounded facts in an appropriate context. Three leading threads are followed. First is the consideration of the mobility of some Spanish mathematicians during a period including World War I and World War II – when Spain was a theoretically neutral country – and the Spanish Civil War (1936–1939). Second, the emergence and socio-political behavior of a dominant mathematical group gathered around Julio Rey Pastor between 1915 and 1936 is also accounted for, as well as its continuity after the Civil War into the 1940s. Third, attention is paid to the migration or interior exile of a number of mathematicians as a consequence of the Civil War. The paper is organized around nine Tables containing information on mobility of mathematicians, doctorates awarded in the mathematical sciences, and mathematical production in Spain during this period, accompanied by statistical résumés and comments on interesting entries. The main conclusions drawn are: 1) a number of integrants of the Rey group, himself included, officially traveled to Austria, France, Germany, Italy, and Switzerland – usually after having obtained doctorates and fixed positions – imported mathematical knowledge into Spain; 2) the group also managed to dominate the mathematical panorama from both the scientific and the sociological viewpoint; 3) social usages in Spanish mathematical affairs established in Spain in the years prior to the Civil War present a clear continuity under the Franco regime once the war was over.
Grammaticalization at an early stage: futurebe going toin conservative British dialects
Authors: TAGLIAMONTE SALI A. , DURHAM MERCEDES , SMITH JENNIFER 
Published: February 2014

The Englishgofuture, a quintessential example of grammaticalization, has shown layering withwillsince at least 1490. To date, most synchronic evidence for this development comes from dialects wherebe going torepresents a sizable proportion of the future temporal reference system. However, in the United Kingdom in the late twentieth century there were still dialects wherebe going towas only beginning to make inroads, representing a mere 10–15 per cent of future contexts. These varieties offer an effective view of the early stages of grammatical change.Statistical analysis of nearly 5,000 variable contexts reveals that the use ofbe going tois increasing across generations, but at different rates, depending on location and orientation to mainstream norms. Major patterns of use mirror previous findings:be going tois favoured for subordinate clauses. However, other widely reported constraints conditioningbe going toare radically different across age groups, exposing contrasts between incipient vs later stages of grammaticalization. In the most conservative dialectsbe going tois strongly correlated with negatives and questions especially in the first person singular. This suggests that these contexts may have been the ‘trigger’ environments for redistribution of meaning of the incoming grammatical form (Hopper & Traugott 1993: 85). The fact that strong effects of negatives and questions endure in contemporary urban varieties (Torres-Cacoullos & Walker 2009) confirms that grammaticalization begins in very specific syntactic contexts, and impacts on the system for generations to come. In contrast, other reported constraints – resistance ofbe going toin the first person singular and extension to inanimates and far future readings – emerge across generations, suggesting they are later developments.Taken together, these findings demonstrate how synchronic dialects show us incremental steps in the grammaticalization process. Comparative sociolinguistic analysis thus offers insights into which patterns define the point of grammaticalization itself; which derive from systemic processes; which can be attributed to discourse routines and collocations; and how these factors converge in shaping the evolution of grammar.

AbstractWe aimed to assess whether birth order affects metabolism and body composition in overweight middle-aged men. We studied 50 men aged 45.6 ± 5.5 years, who were overweight (BMI 27.5 ± 1.7 kg/m2) but otherwise healthy in Auckland, New Zealand. These included 26 first-borns and 24 second-borns. Insulin sensitivity was assessed by the Matsuda method from an oral glucose tolerance test. Other assessments included DXA-derived body composition, lipid profiles, 24-hour ambulatory blood pressure and carotid intima-media thickness. First-born men were 6.9 kg heavier (p = 0.013) and had greater BMI (29.1 vs 27.5 kg/m2; p = 0.004) than second-borns. Insulin sensitivity in first-born men was 33% lower than in second-borns (4.38 vs 6.51; p = 0.014), despite adjustment for fat mass. There were no significant differences in ambulatory blood pressure, lipid profile or carotid intima-media thickness between first- and second-borns. Thus, first-born adults may be at a greater risk of metabolic and cardiovascular diseases.
A complete ancient RNA genome: identification, reconstruction and evolutionary history of archaeological Barley Stripe Mosaic Virus
Authors: Smith Oliver , Clapham Alan , Rose Pam , Liu Yuan , Wang Jun , Allaby Robin G. 
Published: February 2014

AbstractThe origins of many plant diseases appear to be recent and associated with the rise of domestication, the spread of agriculture or recent global movements of crops. Distinguishing between these possibilities is problematic because of the difficulty of determining rates of molecular evolution over short time frames. Heterochronous approaches using recent and historical samples show that plant viruses exhibit highly variable and often rapid rates of molecular evolution. The accuracy of estimated evolution rates and age of origin can be greatly improved with the inclusion of older molecular data from archaeological material. Here we present the first reconstruction of an archaeological RNA genome, which is of Barley Stripe Mosaic Virus (BSMV) isolated from barley grain ~750 years of age. Phylogenetic analysis of BSMV that includes this genome indicates the divergence of BSMV and its closest relative prior to this time, most likely around 2000 years ago. However, exclusion of the archaeological data results in an apparently much more recent origin of the virus that postdates even the archaeological sample. We conclude that this viral lineage originated in the Near East or North Africa and spread to North America and East Asia with their hosts along historical trade routes.
Different yawns, different functions? Testing social hypotheses on spontaneous yawning in Theropithecus gelada
Authors: Leone Alessia , Ferrari Pier Francesco , Palagi Elisabetta 
Published: February 2014

AbstractHere, we tested hypotheses about the potential functions of yawning based on its intensity and social contexts. Due to their spectrum intensity of yawns (covered teeth/YW1; uncovered teeth/YW2; uncovered gums/YW3), geladas are a good model species for this purpose. We suggest that yawns of different intensity can bear different information according to the performer, the context and the behavioural pattern temporally associated to the yawn event. YW3, mainly performed by high ranking males during periods of high social tension, was frequently associated with an auditory component and often accompanied by scratching (a measure of anxiety). YW1 and YW2, preferentially performed by females, were frequently associated to lip smacking, an affiliative display. In conclusion, even though a clear-cut functional distinction of geladas' yawn intensity is difficult, YW1 and YW2 seem to be more linked to affiliative social interactions; whereas, YW3 seems to be more linked to agonistic and tension situations.
Program Intensity and Service Delivery Models in the Schools: SLP Survey Results
Authors: Brandel Jayne , Frome Loeb Diane 
Published: February 2014

Purpose
School-based speech-language pathologists (SLPs) routinely work with team members to make recommendations regarding an intervention program’s intensity and method of service delivery for children with speech and language impairments. In this study, student, SLP, and workplace characteristics that may influence SLPs' recommendations were examined.

Method
Almost 2,000 school-based SLPs completed an online survey about the factors they consider when making recommendations regarding program intensity and service delivery model that students on their caseloads receive.

Results
SLPs reported that student characteristics, rather than SLP or workplace characteristics, were the factors they considered the most when making these recommendations. However, these same SLPs reported that current students on their caseload with severe to moderate disabilities participated in intervention 2–3 times a week for 20–30 min in groups outside of the classroom. Students with the least severe disability received intervention 1 time a week for 20–30 min in groups outside of the classroom.

Conclusion
The limited variety of intervention program intensities and service delivery models used suggests that student characteristics may not be the most important factor considered when making intervention recommendations, as reported by the SLPs. Instead, caseload size and years of practice appear to influence SLPs' recommendations regarding which program intensity and service delivery models to use.
Examining Speech Perception in Noise and Cognitive Functions in the Elderly
Authors: Meister Hartmut , Schreitmüller Stefan , Grugel Linda , Beutner Dirk , Walger Martin , Meister Ingo 
Published: February 2014

Purpose
The purpose of this study was to investigate the relationship of cognitive functions (i.e., working memory [WM]) and speech recognition against different background maskers in older individuals.

Method
Speech reception thresholds (SRTs) were determined using a matrix-sentence test. Unmodulated noise, modulated noise (International Collegium for Rehabilitative Audiology [ICRA] noise 5-250), and speech fragments (International Speech Test Signal [ISTS]) were used as background maskers. Verbal WM was assessed using the Verbal Learning and Memory Test (VLMT; Helmstaedter & Durwen, 1990). Measurements were conducted with 14 normal-hearing older individuals and a control group of 12 normal-hearing young listeners.

Results
Despite their normal hearing ability, the young listeners outperformed the older individuals in all background maskers. These differences were largest for the modulated maskers. SRTs were significantly correlated with the scores of the VLMT. A linear regression model also included WM as the only significant predictor variable.

Conclusions

The results support the assumption that WM plays an important role for speech understanding and that it might have impact on results obtained using speech audiometry. Thus, an individual's WM capacity should be considered with aural diagnosis and rehabilitation. The VLMT proved to be a clinically applicable test for WM. Further cognitive functions important with speech understanding are currently being investigated within the SAKoLA (

Perceived Occlusion and Comfort in Receiver-in-the-Ear Hearing Aids
Authors: Conrad Sara , Rout Ayasakanta 
Published: February 2014

PurposeThis study examined self-perceived occlusion and physical comfort ratings by hearing aid users with receiver-in-the-ear (RITE) hearing aids using different sizes of domes.MethodTwenty-one older adults with hearing impairment were fitted with bilateral RITE hearing aids and tested with 3 dome conditions (open, plus, and power domes) and 1 control condition (participants' own aids). Participants ranked self-perceived occlusion across dome size conditions and across recorded and own voice conditions. Participants also ranked their level of physical comfort across dome sizes.ResultsSelf-perceived occlusion increased as dome size increased, with open domes and participants' own aids resulting in the least amount of occlusion. Although this effect was demonstrated in both recorded and own voice conditions, the effect of dome size was greatest in the own voice test conditions. Perceived physical comfort decreased as dome size increased.ConclusionsSelf-perceived occlusion was greatest for power domes, although average level of occlusion did not exceed moderate occlusion on the rating scale. Perceived physical comfort was highest with the open dome and participants' own aids. Plus and power domes were respectively ranked as more uncomfortable than open domes.
Transitioning From Bimodal to Bilateral Cochlear Implant Listening: Speech Recognition and Localization in Four Individuals
Authors: Potts Lisa G. , Litovsky Ruth Y. 
Published: February 2014

Purpose
The use of bilateral stimulation is becoming common for cochlear implant (CI) recipients with either (a) a CI in one ear and a hearing aid (HA) in the nonimplanted ear (CI&HA—bimodal) or (b) CIs in both ears (CI&CI—bilateral). The objective of this study was to evaluate 4 individuals who transitioned from bimodal to bilateral stimulation.

Method
Participants had completed a larger study of bimodal hearing and subsequently received a second CI. Test procedures from the bimodal study, including roaming speech recognition, localization, and a questionnaire (the Speech, Spatial, and Qualities of Hearing Scale; Gatehouse & Noble, 2004) were repeated after 6–7 months of bilateral CI experience.

Results
Speech recognition and localization were not significantly different between bimodal and unilateral CI. In contrast, performance was significantly better with CI&CI compared with unilateral CI. Speech recognition with CI&CI was significantly better than with CI&HA for 2 of 4 participants. Localization was significantly better for all participants with CI&CI compared with CI&HA. CI&CI performance was rated as significantly better on the Speech, Spatial, and Qualities of Hearing Scale compared with CI&HA.

Conclusions
There was a strong preference for CI&CI for all participants. The variability in speech recognition and localization, however, suggests that performance under these stimulus conditions is individualized. Differences in hearing and/or HA history may explain performance differences.
Impact of Fear of Falling for Patients and Caregivers: Perceptions Before and After Participation in Vestibular and Balance Rehabilitation Therapy
Authors: Honaker Julie A. , Kretschmer Laura W. 
Published: February 2014

Purpose
The purpose of this study was to investigate the impact of fear of falling (FoF) on older patients with dizziness history and their caregivers to better determine holistic needs when developing a patient-family centered approach to falling risk reduction.

Method
A mixed-method design was used, incorporating a phenomenological qualitative approach to explore the impact of FoF in 14 patients and a family member or spouse of each patient. Quantitative analysis was used to further interpret results of interviews conducted before and after participation in a vestibular and balance rehabilitation program designed to reduce falling risk and improve balance confidence.

Results
Qualitative analysis of participant interviews pre and post vestibular rehabilitation revealed lifestyle changes for both participants and family caregivers due to FoF and the need for reducing falling concerns. Patient age showed statistically significant differences in levels of balance confidence, with younger participants (≤ 65 years) showing more concerns about the consequences of falling, even after rehabilitation, than older participants (> 65 years).

Conclusion
The study highlights the impact of FoF on participation and activity levels of patients and family caregivers, as well as the need to thoroughly evaluate falling fears to achieve a holistic rehabilitation outcome.
