Path Dependence in Decision-Making Processes: Exploring the Impact of Complexity under Increasing Returns
Authors: Koch Jochen , Eisend Martin , Petermann Arne 
Published: March 2014

AbstractThe development of path-dependent processes basically refers to positive feedback in terms of increasing returns as the main driving forces of such processes. Furthermore, path dependence can be affected by context factors, such as different degrees of complexity. Up to now, it has been unclear whether and how different settings of complexity impact path-dependent processes and the probability of lock-in. In this paper we investigate the relationship between environmental complexity and path dependence by means of an experimental study. By focusing on the mode of information load and decision quality in chronological sequences, the study explores the impact of complexity on decision-making processes. The results contribute to both the development of path-dependence theory and a better understanding of decision-making behavior under conditions of positive feedback. Since previous path research has mostly applied qualitative case-study research and (to a minor part) simulations, this paper makes a further contribution by establishing an experimental approach for research on path dependence.

Published: March 2014

AbstractBackground
Patients with mildly elevated parathormone (PTH) and calcium levels consistent for primary hyperparathyroidism (pHPT) may present with more underlying multiglandular disease (MGD) and higher operative failure and recurrence rates than those with conventional, or “classic” pHPT. This study compared the clinical characteristics and surgical outcomes of patients with biochemically mild versus conventional pHPT.MethodsA series of 707 consecutive patients underwent initial targeted parathyroidectomy with intraoperative parathormone monitoring (IPM) at a single institution. Biochemically mild (BM) pHPT was defined as PTH > 65 and <100 pg/ml with serum calcium >10.4 and <11 mg/dl. Conventional pHPT was defined as calcium ≥11 mg/dl and PTH ≥ 100 pg/ml. Prospectively collected data for all patients, including operative indication, preoperative laboratory values, imaging, IPM dynamics, and postoperative laboratory values were retrospectively reviewed. Additional assessments included presence of MGD, bilateral neck exploration (BNE), single‐gland volume, and operative failure or success, and recurrence.ResultsOf 60 patients with BM‐pHPT, 46 reported preoperative bone pain, kidney stones, fatigue, and/or mental disturbances. The remaining 14 BM‐pHPT patients underwent parathyroidectomy based on published asymptomatic guidelines. Patients with BM‐pHPT had significantly more kidney stones, MGD, and BNE. Average single‐gland volume and postoperative PTH levels were significantly lower in BM‐pHPT patients. There were no significant differences between groups regarding preoperative localization accuracy, IPM dynamics, or operative success/failure, recurrence rates.ConclusionsBM‐pHPT patients had more MGD requiring BNE but achieved operative success rates similar to those of patients with conventional disease. IPM successfully identifies MGD in BM‐pHPT patients, who should be counseled regarding more extensive operations than limited parathyroidectomy.
Science Teachers’ and Senior Secondary Schools Students’ Perceptions of Earth and Environmental Science Topics
Authors: Dawson Vaille , Carson Katherine 
Published: March 2014

AbstractThis article presents an evaluation of a new upper secondary Earth and Environmental Science (EES) course in Western Australia. Twenty-seven EES teachers were interviewed and 243 students were surveyed about the degree of difficulty, relevance and interest of EES topics in the course. The impact of the course on students’ views about EES topics was also explored. It was found that more than two thirds of the students chose to study EES because of personal interest. However, students perceived that some Earth science topics were difficult, boring or irrelevant. A lack of content knowledge from lower secondary science contributed to these perceptions. Nevertheless, teachers and students perceived that their understanding and attitudes towards environmental science topics such as climate change was improved. With the advent of a new Australian senior secondary science curriculum that includes EES, the implications of the findings for curriculum development and teacher professional development are discussed.

Published: March 2014

AbstractObjectiveAfter the Great Eastern Japan Earthquake and tsunami, the World Health Organization cautioned that evacuees at shelters would be at increased risk of infectious disease transmission; however, the frequency that occurred in this population was not known.MethodsWe reviewed medical charts of evacuees who visited medical clinics at 6 shelters from March 19, to April 8, 2011. Excluded were patients who did not reside within the shelters or whose medical records lacked a name or date. We investigated the frequency of and cumulative incidences of acute respiratory infection [ARI], acute gastroenteritis, acute jaundice syndrome, scabies, measles, pertussis, and tetanus.ResultsOf 1364 patients who visited 6 shelter clinics, 1167 patients (86.1%) were eligible for the study. The median total number of evacuees was 2545 (interquartile range [IQR], 2277-3009). ARI was the most common infectious disease; the median number of patients with ARI was 168.8 per week per 1000 evacuees (IQR, 64.5-186.1). Acute gastroenteritis was the second most common; the median number of patients was 23.7 per week per 1000 evacuees (IQR, 5.1-24.3). No other infectious diseases were observed. The median cumulative incidence of ARI per 1000 evacuees in each shelter was 13.1 person-days (IQR, 8.5–18.8). The median cumulative incidence of gastroenteritis was 1.6 person-days (IQR, 0.3–3.4).ConclusionAfter the Great Eastern Japan Earthquake and tsunami, outbreaks of ARI and acute gastroenteritis occurred in evacuation shelters.

SUMMARYCurrent theories on disease-diversity relationships predict a strong influence of host richness on disease transmission. In addition, identity effect, caused by the occurrence of particular species, can also modify disease risk. We tested the richness effect and the identity effects of mammal species on bovine tuberculosis (bTB), based on the regional bTB outbreak data in cattle from 2005–2010 in Africa. Besides, we also tested which other factors were associated with the regional bTB persistence and recurrence in cattle. Our results suggested a dilution effect, where higher mammal species richness (MSR) was associated with reduced probabilities of bTB persistence and recurrence in interaction with cattle density. African buffalo had a positive effect on bTB recurrence and a positive interaction effect with cattle density on bTB persistence, indicating an additive positive identity effect of buffalo. The presence of greater kudu had no effect on bTB recurrence or bTB persistence. Climatic variables only act as risk factors for bTB persistence. In summary, our study identified both a dilution effect and identity effect of wildlife and showed that bTB persistence and recurrence were correlated with different sets of risk factors. These results are relevant for more effective control strategies and better targeted surveillance measures in bTB.
Parasites as biological tags of marine, freshwater and anadromous fishes in North America from the tropics to the Arctic
Authors: MARCOGLIESE DAVID J. , JACOBSON KYM C. 
Published: March 2014

SUMMARYParasites have been considered as natural biological tags of marine fish populations in North America for almost 75 years. In the Northwest Atlantic, the most studied species include Atlantic cod (Gadus morhua), Atlantic herring (Clupea harengus) and the redfishes (Sebastes spp.). In the North Pacific, research has centred primarily on salmonids (Oncorhynchus spp.). However, parasites have been applied as tags for numerous other pelagic and demersal species on both the Atlantic and Pacific coasts. Relatively few studies have been undertaken in the Arctic, and these were designed to discriminate anadromous and resident salmonids (Salvelinus spp.). Although rarely applied in fresh waters, parasites have been used to delineate certain fish stocks within the Great Lakes-St Lawrence River basin. Anisakid nematodes and the copepod Sphyrion lumpi frequently prove useful indicators in the Northwest Atlantic, while myxozoan parasites prove very effective on the coast and open seas of the Pacific Ocean. Relative differences in the ability of parasites to discriminate between fish stocks on the Pacific and Atlantic coasts may be due to oceanographic and bathymetric differences between regions. Molecular techniques used to differentiate populations and species of parasites show promise in future applications in the field.

BackgroundThe high rate of depression among children of depressed mothers is well known. Suggestions that improvement in maternal acute depression has a positive effect on the child have emerged. However, data on the mechanisms of change have been sparse. The aim was to understand how remission and relapse in the mother might explain the changes in the child's outcome.MethodParticipants were 76 depressed mothers who entered into a medication clinical trial for depression and 135 of their eligible offspring ages 7–17 years. The mothers and children were assessed at baseline and periodically over 9 months by independent teams to understand the relationship between changes in children's symptoms and functioning and maternal remission or relapse. The main outcome measures were, for mothers, the Hamilton Depression Rating Scale (HAMD), the Social Adjustment Scale (SAS) and the Parental Bonding Instrument (PBI) and, for children, the Children's Depression Inventory (CDI), the Columbia Impairment Scale (CIS), the Multidimensional Anxiety Scale for Children (MASC) and the Children's Global Assessment Scale (CGAS).ResultsMaternal remission was associated with a decrease in the child's depressive symptoms. The mother's subsequent relapse was associated with an increase in the child's symptoms over 9 months. The effect of maternal remission on the child's improvement was partially explained by an improvement in the mother's parenting, particularly the change in the mother's ability to listen and talk to her child, but also reflected in her improvement in parental bonding. These findings could not be explained by the child's treatment.ConclusionsA depressed mother's remission is associated with her improvement in parenting and a decrease in her child's symptoms. Her relapse is associated with an increase in her child's symptoms.
Ages and Stages: the place of theatre in the lives of older people

Published: March 2014

ABSTRACTDespite the growing interest amongst gerontologists and literary and cultural scholars alike, in arts participation, ageing and the artistic outputs of older people, comparatively little attention has yet been paid to theatre and drama. Likewise, community or participatory theatre has long been used to address issues affecting marginalised or excluded groups, but it is a presently under-utilised medium for exploring ageing or for conveying positive messages about growing older. This paper seeks to address this lack of attention through a detailed case study of the place of one particular theatre – the Victoria/New Victoria Theatre in North Staffordshire, England – in the lives of older people. It provides an overview of the interdisciplinaryAges and Stagesproject which brought together social gerontologists, humanities scholars, psychologists, anthropologists and theatre practitioners, and presents findings from: the archival and empirical work exploring the theatre's pioneering social documentaries and its archive; individual/couple and group interviews with older people involved with the theatre (as audience members, volunteers, employees and sources); and ethnographic data gathered throughout the study. The findings reaffirm the continuing need to challenge stereotypes that the capacity for creativity and participation in later life unavoidably and inevitably declines; show how participation in creative and voluntary activities shapes meanings associated with key life transitions such as bereavement and retirement; and emphasise the positive role that theatre and drama can play as a medium for the inclusion of both older and younger people.
How similar, how different? On Dutch media depictions of older and younger people
Authors: LEPIANKA DOROTA 
Published: March 2014

ABSTRACTBy providing information on society at large, the media help to establish and maintain relations between various social groups, such as between younger and older people. They may also disturb the formation or maintenance of such relations,e.g.by stimulating the ‘othering’ of the out-group members. The aim of the present study was to trace how the different strategies of ‘othering’ are applied by Dutch news media in their portrayal of older and younger citizens. The analysis showed that the most notable discrepancies in the media coverage of the two age groups appear in (the nature of) their evaluation. While the negative descriptors of older characters relate more frequently to their (alleged) incompetence, the negative depictions of younger actors refer predominantly to their lack of benevolence. In the case of positive evaluations the reverse is true: older characters are more often presented as warm and younger people as competent. The results of the study are interpreted in the light of literature on social distance and (social) practices of ‘othering’.
Humanoid robot upper body motion generation using B-spline-based functions
Authors: Ruchanurucks M. 
Published: March 2014

SUMMARYThis paper aims to represent a human's upper body motion using a humanoid robot. As a robot has different physical limitations than a human, we present a method that can filter the trajectories to meet the limitations. The filtering can be used directly and also can be used as a constraint for optimization. It will be shown to be applicable both offline and online. Many physical attributes, namely angle, collision, velocity, and dynamic torque, are represented as B-spline explicit functions. The B-spline coefficients are then calculated to limit the physical attributes. This explicit method can guarantee that many limits are met. Hence, it is better than many methods that only reduce such physical attributes using objective functions.

Published: March 2014

Abstract:In dioecious plant species different frugivore activity between genders may influence the abundance and richness of the seedling banks underneath their canopies throughout seed removal and dispersal. In the tropical dry forest of Chamela, on the Pacific Coast of Mexico, the role of S. purpurea female trees as nucleation sites of regeneration was investigated. The standing density, species richness and dispersal syndrome of woody seedlings (i.e. trees and shrubs, 10–100 cm tall) recruited underneath and outside the canopy of 10 male and 10 female S. purpurea trees were recorded in a total of 160 1-m2 plots. Total density was greater in seedling communities associated with female trees (i.e. underneath and outside their canopies) as compared with male trees (231 vs. 153 seedlings, respectively); whereas overall species richness was greater underneath female canopies. Further, the density of zoochorous species were greater underneath the canopy of S. purpurea females (range = 0–5 plants m−2), than elsewhere (outside female canopies, range = 0–3 plants m−2; underneath and outside male canopies, range = 0–2 plants m−2), suggesting a directional dispersal bias towards them. Females of dioecious plant species may act as nucleation sites of initial seedling recruitment in tropical dry forests.
Projecting the impact of climate change on the transmission of Ross River virus: methodological challenges and research needs

Published: March 2014

SUMMARYRoss River virus (RRV) is the most common vector-borne disease in Australia. It is vitally important to make appropriate projections on the future spread of RRV under various climate change scenarios because such information is essential for policy-makers to identify vulnerable communities and to better manage RRV epidemics. However, there are many methodological challenges in projecting the impact of climate change on the transmission of RRV disease. This study critically examined the methodological issues and proposed possible solutions. A literature search was conducted between January and October 2012, using the electronic databases Medline, Web of Science and PubMed. Nineteen relevant papers were identified. These studies demonstrate that key challenges for projecting future climate change on RRV disease include: (1) a complex ecology (e.g. many mosquito vectors, immunity, heterogeneous in both time and space); (2) unclear interactions between social and environmental factors; and (3) uncertainty in climate change modelling and socioeconomic development scenarios. Future risk assessments of climate change will ultimately need to better understand the ecology of RRV disease and to integrate climate change scenarios with local socioeconomic and environmental factors, in order to develop effective adaptation strategies to prevent or reduce RRV transmission.
‘Some banglyng about the customes’: Popular Memory and the Experience of Defeat in a Sussex Village, 1549–1640
Authors: WOOD ANDY 
Published: March 2014

AbstractThis article deploys a body of remarkably detailed witness statements to interrogate the nature of popular memory and social conflict in Petworth, Sussex. These depositions are located in two specific contexts: a struggle between the tenants of Petworth and the ninth earl of Northumberland (1591 – 1608) and the broader pattern of resistance and negotiation in the village between the ‘commotion time’ of 1549 and the calling of the Short Parliament. The essay presents a micro-history of local struggles over land, rights and resources and the findings open up questions within the recent historiography of early modern social relations, undermining the notion that authority was flexibly negotiated between ruler and ruled. Instead, it locates negotiation within social structures that gave a powerful advantage to the gentry and nobility. In this respect, the essay builds upon the return in social history to questions of economic inequality and imbalances of political agency.
Sir George Stapledon and the Cahn Hill Improvement Scheme: A Dream Turned Reality
Authors: MOORE-COLYER RICHARD 
Published: March 2014

AbstractR. G. Stapledon was one of the most profound of twentieth-century thinkers on rural and landscape issues. Scientist, philosopher and teacher, he was an unconventional figure who, with a dedicated team of loyal colleagues, established the basic biology and breeding systems of the Graminae at the Welsh Plant Breeding Station in the 1920s and 1930s. They subsequently bred a range of grass and clover varieties which were to transform grazing lands throughout the British Empire. To Stapledon the grasslands of an island nation were of vital strategic importance and if Britain were to prepare for a future war, her grasslands would require dramatic improvement if they were to provide a reserve of fertility. In proposing and implementing a vast scheme of renovation of the uplands of Wales, against the fervent opposition of the economists, as a means of both improving agricultural output and stemming the haemorrhage of depopulation, he demonstrated the practical feasibility of land improvement. In so doing he provided a template for the massively subsidised post-war programme of land improvement which was so dramatically to change the face of Britain. This article describes the evolution and conduct of the Cahn Hill Improvement Scheme which was not only one of the most ambitious outdoor ‘experiments’ of the last century, but in a sense, a metaphor for nation-building itself.
The story in the mind: the effect of 3D gameplay on the structuring of written L2 narratives
Authors: Neville David O. 
Published: March 2014

AbstractThe article reports on a mixed-methods study evaluating the use of a three-dimensional digital game-based language learning (3D-DGBLL) environment to teach German two-way prepositions and specialized vocabulary within a simulated real-world context of German recycling and waste management systems. The study assumed that goal-directed player activity in this environment would configure digital narratives, which in turn would help study participants in the experimental group to co-configure story maps for ordering and making sense of the problem spaces encountered in the environment. The study further assumed that these participants would subsequently rely on the story maps to help them structure written L2 narratives describing an imagined personal experience closely resembling the gameplay of the 3D-DGBLL environment. The study found that immersion in the 3D-DGBLL environment influenced the manner in which the second language was invoked in these written narratives: Participants in the experimental group produced narratives containing more textual indicators describing the activity associated with the recycling and waste management systems and the spaces in which these systems are located. Increased usage of these indicators suggest that participants in the experimental group did indeed rely on story maps generated during 3D gameplay to structure their narratives, although stylistic and grammatical features of the narratives suggest, however, that changes could be made to the curricular implementation of the 3D-DGBLL environment. The study also puts forward ideas for instructional best practices based on research findings and suggests future areas of development and investigation.
