Leaders benefit followers in the collective movement of a social sawfly

The challenges of maintaining cohesion while making collective decisions in social or aggregating insects can result in the emergence of a leader or leaders. Larval aggregations of the steel-blue sawfly Perga affinis forage nocturnally, and some larvae lead the aggregation on foraging trips more often than expected by chance. We investigated the relationship between these leader and follower roles by comparing the weight and growth of individual larvae with different roles. Our observations reveal no significant difference between the growth of leaders and followers, suggesting that the role of leadership may not provide direct foraging benefits. However, by experimentally manipulating the social structure of larval aggregations, we found that individuals within aggregations that comprise a mixture of leaders and followers enjoy higher growth rates than those in aggregations comprising a single behavioural type. These data demonstrate, for the first time, individual benefits to maintaining a balance of leader and follower roles within larval aggregations, and highlight the importance of considering the perspectives of both leaders and followers when investigating the evolutionary significance of this behavioural variation within animal groups.

Performance and narrative, bodies and movement in the construction of places and objects, spaces and knowledges: The case of the Maltese megaliths

The article explores the ways knowledge and space are co-produced performatively through bodily movement in an examination of the Maltese megaliths the first complex stone structures in the world. It is argued that knowledge is best seen as spatialized narratives of human actions and objects as materialized forms of those spatial narratives. Rewriting our social and historical narratives so that the performativity of place, space and knowledge is restored opens new possibilities for rethinking the social and material order.

Tourism, globalization, social externalities, and domestic welfare

One of the impacts of globalisation has been the growth in tourism and mobility of capital. This paper examines the welfare effect of tourism on the host economy with imperfect competition. Three channels that affects domestic welfare by tourism are: social externalities accompanied with tourists, the terms of trade effect via rises in the non-tradable prices, and the resource movement effect to the manufacturing sector. Owing to the positive terms-of-trade effect and/or the beneficial resource movement effect, the optimal levels of tourism occur at the situations that tourists bring negative social externalities to the economy.

Fundamental movement skills - How do primary school children perform? The 'Move it Groove it' program in rural Australia

Child Fundamental Movement Skills (FMS) underpin active lifestyles yet little is known of their distribution and mastery.

‘Move it Groove it’ project rated proficiency of primary school children (n=1045, 18 schools) in skills of balance, throw, catch, sprint, hop, kick, side gallop and jump. Rating categories were ‘mastery’, ‘near mastery’ or ‘poor’ (ie mastered all, all but one, or less of the five to six components of an FMS).

Less than half of all child tests were rated at mastery (21.3%) or near mastery (25.7%) level. In grade three, 75.4% of children achieved mastery or near mastery (MNM) in static balance but less than half did so for any other FMS. In grade four, 59.0% achieved MNM in the side gallop and 56.0% in the catch but less than half did so for any other FMS.

Although the highest percent mastery for both genders was for the balance, the skills best performed thereafter by boys (throw and kick) rated poorest for girls. Conversely the hop and side gallop which rated, after balance, as the skills best mastered by girls, were among the more poorly performed skills for boys.

The low prevalence of FMS mastery found in this survey suggests that there may be great potential to improve fundamental movement skills of primary aged children in many parts of rural Australia. Even if the aim were for children to achieve near mastery levels, the improvement could be substantial in every skill category. Where appropriate, gender differences in mastery might easily be addressed by tailored physical education programs and modification of social and physical environments.

Assessment of movement participation for children with developmental coordination disorders

The Caregiver Assessment of Movement Participation was developed to identify children of 5-10 years old for movement participation difficulties in home contexts. Its psychometric properties were investigated including its usefulness as a screening instrument using both classical test theory methods and Rasch analysis. Results confirmed its validity and reliability.

Fundamental movement skills in children and adolescents : review of associated health benefits

The mastery of fundamental movement skills (FMS) has been purported as contributing to children's physical, cognitive and social development and is thought to provide the foundation for an active lifestyle. Commonly developed in childhood and subsequently refined into context- and sport-specific skills, they include locomotor (e.g. running and hopping), manipulative or object control (e.g. catching and throwing) and stability (e.g. balancing and twisting) skills. The rationale for promoting the development of FMS in childhood relies on the existence of evidence on the current or future benefits associated with the acquisition of FMS proficiency. The objective of this systematic review was to examine the relationship between FMS competency and potential health benefits in children and adolescents. Benefits were defined in terms of psychological, physiological and behavioural outcomes that can impact public health. A systematic search of six electronic databases (EMBASE, OVID MEDLINE, PsycINFO, PubMed, Scopus and SportDiscus) was conducted on 22 June 2009. Included studies were cross-sectional, longitudinal or experimental studies involving healthy children or adolescents (aged 3–18 years) that quantitatively analysed the relationship between FMS competency and potential benefits. The search identified 21 articles examining the relationship between FMS competency and eight potential benefits (i.e. global self-concept, perceived physical competence, cardio-respiratory fitness [CRF], muscular fitness, weight status, flexibility, physical activity and reduced sedentary behaviour). We found strong evidence for a positive association between FMS competency and physical activity in children and adolescents. There was also a positive relationship between FMS competency and CRF and an inverse association between FMS competency and weight status. Due to an inadequate number of studies, the relationship between FMS competency and the remaining benefits was classified as uncertain. More longitudinal and intervention research examining the relationship between FMS competency and potential psychological, physiological and behavioural outcomes in children and adolescents is recommended.

Representação espacial na cognição ambiental urbana : aspectos de uso do solo e presença social

In the present paper different representations of urban character that influence environmental cognition are tested. Two main features involved in urban identity are the functional and social aspects of urban environment. Land use of lots is aggregated into different intensity measures that explore functional characterization of urban spaces. Social presence related to residential use and movement in urban space are also evaluated by intensity and social-economic characteristics. All selected attributes come from normal governmental data bases. Thus, one of the challenges is to transpose/interchange data from different scale units into a unique spatial representation unit, creating a common spatial base in a GIS environment.

Genes and song : genetic and social connections in fragmented habitat in a woodland bird with limited dispersal

Understanding the processes leading to population declines in fragmented landscapes is essential for successful conservation management. However, isolating the influence of disparate processes, and dispersal in particular, is challenging. The Grey Shrike-thrush, Colluricincla harmonica, is a sedentary woodland-dependent songbird, with learned vocalizations whose incidence in suitable habitat patches falls disproportionally with decline in tree cover in the landscape. Although it has been suggested that gaps in tree cover might act as barriers to its dispersal, the species remains in many remnants of native vegetation in agricultural landscapes, suggesting that it may have responded to habitat removal and fragmentation by maintaining or even increasing dispersal distances. We quantified population connectivity of the Grey Shrike-thrush in a system fragmented over more than 120 years using genetic (microsatellites) and acoustic (song types) data. First, we tested for population genetic and acoustic structure at regional and local scales in search of barriers to dispersal or gene flow and signals of local spatial structuring indicative of restricted dispersal or localized acoustic similarity. Then we tested for effects of habitat loss and fragmentation on genetic and acoustic connectivity by fitting alternative models of mobility (isolation-by-distance [the null model] and reduced and increased movement models) across treeless vs. treed areas. Birds within 5 km of each other had more similar genotypes and song types than those farther away, suggesting that dispersal and song matching are limited in the region. Despite restricted dispersal detected for females (but not males), populations appeared to be connected by gene flow and displayed some cultural (acoustic) connectivity across the region. Fragmentation did not appear to impact greatly the dispersal of the Grey Shrike-thrush: none of the mobility models fit the genetic distances of males, whereas for females, an isolation-by-distance model could not be rejected in favor of the models of reduced or increased movement through treeless gaps. However, dissimilarities of the song types were more consistent with the model of reduced cultural connectivity through treeless areas, suggesting that fragmentation impedes song type sharing in the Grey Shrike-thrush. Our paper demonstrates that habitat fragmentation hinders important population processes in an Australian woodland bird even though its dispersal is not detectably impacted.

Incorrigible and undisciplined lines in visual social research : ways of ‘writing’ and ‘drawing’ at the interstices

In this paper the author traces the possibilities afforded by engaging with the aesthetic, historic and socio-political nature of shodo (Japanese calligraphy) as an intersectional space. Shodo literally translated as 'the way of writing' is an artistic practice bringing together ink, brush and paper. It is simultaneously a juncture between studied discipline and an ongoing mediation of subjectivities. The calligrapher/writer/drawer communicates to the reader through the bold or subtle brush strokes, the pressure and movement at the completion of each stroke. The calligrapher/writer/drawer draws across the boundaries of text and image to meet the reader blurring the lines between subject and object. This discussion re-examines the hierarchical binaries of writing/drawing, text/image, self/Other as they play out from vanishing lines of distinction between truth and conjecture. Crossing these binaries opens up opportunity for decentring and questioning representational practice by enabling other possible meanings and practices to emerge (Lather, 2007). I work from a stance of theoretical promiscuity in order to disrupt constitutive discourses and restore the liminal in social research. Drawing across the fragments of research projects I illustrate the generative and speculative space of visualising pedascapes in educational research.

The multifaith movement : global risks and cosmopolitan solutions

This book documents the ultramodern rise of the multifaith movement, as mulitfaith initiatives have been increasingly deployed as cosmopolitan solutions to counter global risks such as terrorism and climate change at the turn of the 21st century. These projects aim to enhance common security, particularly in Western societies following the events of September 11, 2001 and the July 2005 London bombings, where multifaith engagement has been promoted as a strategy to counter violent extremism. The author draws on interviews with 56 leading figures in the field of multifaith relations, including Paul Knitter, Eboo Patel, Marcus Braybrooke, Katherine Marshall, John Voll and Krista Tippett.
Identifying the principle aims of the multifaith movement, the analysis explores the benefits—and challenges—of multifaith engagement, as well as the effectiveness of multifaith initiatives in countering the process of radicalization. Building on notions of cosmopolitanism, the work proposes a new theoretical framework termed ‘Netpeace’, which recognizes the interconnectedness of global problems and their solutions. In doing so, it acknowledges the capacity of multi-actor peacebuilding networks, including religious and state actors, to address the pressing dilemmas of our times. The primary intention of the book is to assist in the formation of new models of activism and governance, founded on a ‘politics of understanding’ modeled by the multifaith movement.

Brief report: children with ADHA without co-morbid autism do not have impaired motor proficiency on the Movement Assessment Battery for Children

Motor proficiency was investigated in a sample of children with Attention Deficit Hyperactivity Disorder-Combined type (ADHD-CT) without autism. Accounting for the influence of co-morbid autistic symptoms in ADHD motor studies is vital given that motor impairment has been linked to social–communication symptoms in children who have co-morbid ADHD and autistic-like symptoms. Two groups of children aged between 7–14 years were recruited; children with ADHD-CT (n = 16; mean age 10 years, 7 months [SD = 1 year, 10 months]) and a typically developing (n = 16; mean age 10 years, 6 months [SD = 2 years, 6 months]) group. Motor proficiency was measured using the Movement Assessment Battery for Children-2nd Edition, ADHD symptoms were measured using the Conner’s Parent Rating Scale. Children with ADHD-CT who had been screened for co-morbid autism did not display motor difficulties on the MABC-2. Higher levels of inattention, but not hyperactivity or impulsivity were associated with poorer motor performance. These findings provide indirect evidence that the motor problems that children with ADHD experience may be related to co-occurring social responsiveness impairments.

The house of service: the Gulen movement and Islam's third way

David Tittensor offers a groundbreaking new perspective on the Gülen movement, a Turkish Muslim educational activist network that emerged in the 1960s and has grown into a global empire with an estimated worth of $25 billion. Named after its leader Fethullah Gülen, the movement has established more than 1,000 secular educational institutions in over 140 countries, aiming to provide holistic education that incorporates both spirituality and the secular sciences.

Despite the movement's success, little is known about how its schools are run, or how Islam is operationalized. Drawing on thirteen months of ethnographic fieldwork in Turkey, Tittensor explores the movement's ideo-theology and how it is practiced in the schools. His interviews with both teachers and graduates from Africa, Indonesia, Central Asia, and Turkey show that the movement is a missionary organization, but of a singular kind: its goal is not simply widespread religious conversion, but a quest to recoup those Muslims who have apparently lost their way and to show non-Muslims that Muslims can embrace modernity and integrate into the wider community. Tittensor also examines the movement's operational side and shows how the schools represent an example of Mohammad Yunus's social business model: a business with a social cause at its heart.

The House of Service is an insightful exploration of one of the world's largest transnational Muslim associations, and will be invaluable for those seeking to understand how Islam will be perceived and practiced in the future.

Social media's impact on journalism : a study of media's coverage of anti-corruption protests in India

The year 2011 was memorable for many in India – for those who participated in numerous anti-corruption protests, and for those who witnessed these protests via all pervasive mainstream news media. This paper will use inter-media agenda-setting discourse to explain the Indian media’s coverage of the so-called ‘Anna movement’. It will outline how the use of mobile and social media platforms by the ‘India Against Corruption’ organisers and the educated middle class influenced the mainstream media’s coverage of the protests. The paper will consider the implication of this coverage, in the light of the unique position of power the Indian news media has in this transitioning society.

Learning latent activities from social signals with hierarchical dirichlet processes

Understanding human activities is an important research topic, most noticeably in assisted-living and healthcare monitoring environments. Beyond simple forms of activity (e.g., an RFID event of entering a building), learning latent activities that are more semantically interpretable, such as sitting at a desk, meeting with people, or gathering with friends, remains a challenging problem. Supervised learning has been the typical modeling choice in the past. However, this requires labeled training data, is unable to predict never-seen-before activity, and fails to adapt to the continuing growth of data over time. In this chapter, we explore the use of a Bayesian nonparametric method, in particular the hierarchical Dirichlet process, to infer latent activities from sensor data acquired in a pervasive setting. Our framework is unsupervised, requires no labeled data, and is able to discover new activities as data grows. We present experiments on extracting movement and interaction activities from sociometric badge signals and show how to use them for detecting of subcommunities. Using the popular Reality Mining dataset, we further demonstrate the extraction of colocation activities and use them to automatically infer the structure of social subgroups. © 2014 Elsevier Inc.
