Managing Resource-related Conflict
Authors: Roy Vita
Published: October 2016

States endowed with valuable lootable natural resources tend to experience longer armed conflicts, more intense fighting in extractive regions and face a higher risk of recurring conflict than states without such resources. At the same time, many states defy resource-fueled conflict traps and set up institutional arrangements that seem to alleviate the risk of recurring conflict. However, policy makers and academics alike lack a sound understanding of the link between postconflict stabilization and strategies of resource management that often escape the paradigm of “good resource governance.” This article contributes to the questions of how to conceptualize diverse institutional arrangements in the resource sector and how to link these emerging institutions to postconflict stabilization. I develop a theoretical framework that predicts the risk of recurring armed conflict based on lootable resource management strategies and conditioning factors. The framework is then tested on a unique event history dataset. Results support the stabilizing effects of inclusive and publicly accountable modes of resource management as advocated for by proponents of “good resource governance.” Alternative resource management strategies either increase the risk of conflict recurrence or interact with other variables, changing the prospects of postconflict stability in important ways.
Opening the Scientific Expert’s Black Box
Authors: Carr Sophie , Piasecki Emma , Tully Gillian , Wilson Tim J
Published: October 2016

The work of forensic scientists, by providing specialist assistance beyond the normal experience or knowledge of the factfinders, can be elusive to the law’s traditional probative safeguards. These safeguards, in any case, only apply to the small proportion of such evidence actually tested in court. The specialist nature of the scientific work and the knowledge and understanding needed by users with a non-scientific background makes trust in forensic science problematic if conceptualised in binary terms. A systematic review of the development of the quality controls for the production and use of expert scientific evidence demonstrates that critical trust, as an organising principle, does offer a continuum (ranging from scepticism to acceptance) for assessing the reliability and use of forensic science evidence. Despite progressive reform in forensic science, significant risks remain. These risks are both (i) scientific, including the fragmentation of scientific interpretation and the assurance that all providers and/or processes can meet the necessary standards, and (ii) professional, ranging from the timely provision of information to the ability of counsel to critically test the evidence in a manner intelligible to the factfinders.
No More Laissez Faire? Expert Evidence, Rule Changes and Reliability
Authors: Davies Gemma , Piasecki Emma
Published: October 2016

The apparent link between miscarriages of justice in prosecutions involving expert evidence and the level of training provided to the legal profession (the Bar in particular) and the judiciary in respect of such evidence was highlighted in 2005 with the publication of the House of Commons Science and Technology Committee Report Expert Evidence on Trial.2 The Law Commission, in the 2011 Report Expert Evidence in England and Wales3 subsequently comprehensively addressed the same issue. This article seeks to consider why appropriate training in relation to expert evidence is so necessary and questions whether, in the context of the amendments to what is now Part 19 of the Criminal Procedure Rules (CrimPR19) and Part 19A of the Criminal Practice Direction (CrimPD19A), there have been sufficient developments in training to effect a cultural change within the legal profession and ultimately substantially reduce the risk of future miscarriages of justice. Finally, the article debates the nature of required training, arguing that much more detailed training is required than has previously been considered and addresses where this training best sits.
Governing urbanism: Urban governance studies 1.0, 2.0 and beyond
Authors: McCann Eugene
Published: October 2016

Governance has been a key concept in urban studies since the late 1980s. This paper reflects on its use and development over the past 25 years and identifies contemporary innovations and concerns that will likely define the future of urban governance studies. The paper argues that to fully understand the impacts of governance approaches on our understanding of cities, urban regions and global urbanism, we must address how urbanism, rather than urbanisation, is governed. An attention to urbanism highlights a wider range of scholarly work on how the mutually constitutive relationships between the development of built environments and the identities, practices, struggles and opportunities of everyday social life are governed. In introducing 15 contributions from the archives of Urban Studies, the paper employs a heuristic framing – urban governance studies (UGS) 1.0, 2.0, and beyond – to show that, while governance as a contemporary critical concept gained prominence through the work of Marxian political economists concerned largely with urbanisation (UGS 1.0), other work, analysing the governance of other aspects of urbanism, including identity and citizenship (UGS 2.0), also has a significant history. The paper then points to ways in which urban governance studies grapple with future-defining challenges, such as climate change, and new framings, such as the ‘smart city’, while extending the scope of their analyses both temporally and spatially. The paper concludes by pointing to gaps and potential topics for ongoing attention.

Published: October 2016

Additional intervention and medical treatment of complications may follow the primary treatment of a ureteral stone. We investigated the cost of the treatment of ureteral stone(s) within 45 days after initial intervention by means of retrospective analysis of the National Health Insurance Research Database of Taiwan. All patients of ages ≥20 years diagnosed with ureteral stone(s)( International Classification of Diseases, Ninth Revision, Clinical Modification/ICD-9-CM: 592.1) from January 2001 to December 2011 were enrolled. We included a comorbidity code only if the diagnosis appeared in at least 2 separate claims in a patient’s record. Treatment modalities (code) included extracorporeal shock-wave lithotripsy (SWL; 98.51), ureteroscopic lithotripsy (URSL; 56.31), percutaneous nephrolithotripsy (PNL; 55.04), (open) ureterolithotomy (56.20), and laparoscopy (ie, laparoscopic ureterolithotomy; 54.21). There were 28 513 patients with ureteral stones (13 848 men and 14 665 women) in the randomized sample of 1 million patients. The mean cost was 526.4 ± 724.1 United States Dollar (USD). The costs of treatment were significantly increased in patients with comorbidities. The costs of treatment among each primary treatment modalities were 1212.2 ± 627.3, 1146.7 ± 816.8, 2507.4 ± 1333.5, 1533.3 ± 1137.1, 2566.4 ± 2594.3, and 209.8 ± 473.2 USD in the SWL, URSL, PNL, (open) ureterolithotomy, laparoscopy (laparoscopic ureterolithotomy), and conservative treatment group, respectively. In conclusion, URSL was more cost-effective than SWL and PNL as a primary treatment modality for ureteral stone(s) when the possible additional costs within 45 days after the initial operation were included in the calculation.
Not Funny? The Effects of Factual Versus Sarcastic Journalistic Responses to Uncivil User Comments
Authors: Ziegele Marc , Jost Pablo B.
Published: October 2016

Incivility in user comments on news websites has been discussed as a significant problem of online participation. Previous research suggests that news outlets should tackle this problem by interactively moderating uncivil postings and asking their authors to discuss more civilized. We argue that this kind of interactive comment moderation as well as different response styles to uncivil comments (i.e., factual vs. sarcastic) differently affect observers’ evaluations of the discussion atmosphere, the credibility of the news outlet, the quality of its stories, and ultimately observers’ willingness to participate in the discussions. Results from an online experiment show that factual responses to uncivil comments indirectly increase participation rates by suggesting a deliberative discussion atmosphere. In contrast, sarcastic responses indirectly deteriorate participation rates due to a decrease in the credibility of the news outlet and the quality of its stories. Sarcastic responses however increase the entertainment value of the discussions.
Measuring the Impact of Psychological Trauma Change on Recidivism Among Juvenile Justice–Involved Youth
Authors: Tossone Krystel , Butcher Fredrick , Kretschmar Jeff
Published: October 2016

Population heterogeneity and intra-individual change are often overlooked in recidivism research. This study employs latent transition analysis of psychological trauma from intake into a juvenile justice diversion program until termination, followed by modeling of recidivism. A comparison model of a logistic regression without latent variables is also presented, to answer whether the same results would have been achieved without using latent variable modeling. Results indicate that juvenile justice–involved (JJI) youth are assigned into four psychological trauma classes at intake, and three at termination. Latent status membership predicts 6-month recidivism ( p = .03). Those who begin in classes that have Depression, Post-Traumatic Stress, and Anger have higher odds of recidivating than those who demonstrate generally high or low trauma symptoms at intake. The comparison regression model found no significant relationship between the five trauma symptom domains and recidivism. Implications for employing latent variable modeling and person-centered analyses for recidivism research are discussed.
The Association of Sleep Disturbances With Quality of Life in Heart Failure Patient–Caregiver Dyads
Authors: Al-Rawashdeh Sami Y. , Lennie Terry A. , Chung Misook L.
Published: October 2016

Sleep disturbance is common in patients with heart failure and their family caregivers. The purpose of this study was to determine whether sleep disturbances of patients and their spousal caregivers predicted their own and their partners’ quality of life (QoL) in 78 heart failure patient–spousal caregiver dyads. Sleep disturbance was assessed using a composite score of four common sleep complaints. QoL was assessed by the physical and mental well-being subscales of the Short-Form 12 Health Survey. The multilevel dyadic actor–partner interdependence model analysis was used to determine the association between sleep disturbance and QoL. Each individual’s sleep disturbance predicted their own poor physical and mental well-being while spousal caregivers’ sleep disturbance predicted their partners’ mental well-being. Results indicated that patients’ mental well-being is sensitive to their spouses’ sleep disturbance. Interventions targeting improving sleep and QoL may have to include both patients and spousal caregivers.
Holding together logistical worlds: Friction, seams and circulation in the emerging ‘global warehouse’
Authors: Gregson Nicky , Crang Mike , Antonopoulos Constantinos N
Published: October 2016

This paper examines logistics in the space of action between production and consumption to provide (1) a rethinking of logistical power, not as seamless flow but through seam space and friction, and (2) a re-conceptualisation of cargo mobilities, as the dynamic articulation between things being freight cargo, and being products and goods. The paper uses empirical research on cargo movement in Northern Europe to reveal the frictions resulting from freight cargo’s spatial ordering and from systemic imbalances in trade flows. It shows the multiple lines of friction produced by and productive of cargo mobilities across maritime and terrestrial space. It argues that logistics is an art of accommodating this and creating competitive advantage through making interruptions, discontinuities or seams in the spaces of flow. This is done through different temporal logics of ordering physical cargo sequenced across maritime and terrestrial space. The paper further shows the frictions between the physical spaces and flows of freight and the corresponding code-space and data flows. Bespoke corporate systems translate freight cargo to data and provide visibility to actors such that logistical and regulatory work can be anticipated and planned. Yet they do so through specific lines of sight. Bespoke systems also create seam spaces between networks as they simultaneously make frictions between rival corporate systems. The effect is to generate a contested, fractured space in which at stake is whether logistics works to further the interests of lead actors in the distribution chain linking up the global factory or as a tool of supply chain capitalism that spans continents and connects material supply to consumer, in which logistical actors increasingly perform the role of contractors in a global warehouse.
Street dogs at the intersection of colonialism and informality: ‘Subaltern animism’ as a posthuman critique of Indian cities
Authors: Narayanan Yamini
Published: October 2016

This paper argues that colonial biopolitics and informality co-produce a ‘state of exception' for nonhuman animals in cities, based on the socio-political construct of a human/animal binary. This state is enacted by exceptionalising animals as not-persons, and humans as not-animals, and through urbanisation, a uniquely human claim on land. ‘Colonial' is understood in an anthropocentric sense of (privileged) human imperialism over nonhumans and poor humans. Informality, a carefully produced condition that is exceptional to formal governance and planning, legitimises the view of animals (and poor humans) as ‘trespassers' in urban spaces. This paper examines street canines in Indian cities, demonstrating their marginalisation and eviction at the intersection of colonialism and informality. Last, this paper builds upon ‘subaltern urbanism’ that recognises the agency inherent in marginalised citizens and spaces, to conceptualise ‘subaltern animism’ as a way of acknowledging animal spaces and citizenship in the city.
Gaps Between Self-Rated Job Importance and Abilities for Community Health Workers in Massachusetts
Authors: Rataj Suzanne , Weber Luise , DiFulvio Gloria , Heffernan Dawn , Gerber Dan , Chipkin Stuart R.
Published: October 2016

Introduction

Community health workers (CHWs) serve increasingly active roles in clinical care and population health. To identify priorities for training programs, we developed a training needs assessment (TNA) tool by integrating and distilling core competencies previously identified by various national and state agencies.

Methods

CHWs were asked to self-rate, using a 4-point scale, the importance to their work and their ability to perform 49 competencies categorized under 10 domains. A difference score—Ability minus Importance—was calculated to determine relative Need.

Results

The 96 CHWs who completed the TNA were mostly female (80%) and Latino (40%). While CHWs indicated training was needed for all competencies, the scores ranged from −0.04 to −0.45, on a scale running from 0 to −3, where larger negative numbers indicate higher need. In general, there was a high level of congruence between individual competencies with high Need and domains with Need, with few outliers. Competencies with high Need scores related to culture, case assessment and coordination, and behavior change. CHWs rated client-based competencies higher than population health competencies in Ability scores (3.43 vs. 3.05, respectively) and Importance scores (3.70 vs. 3.35, respectively). However, overall Need scores showed no difference between client-based and public health-based competencies.

Conclusion

CHWs can successfully rate the importance of core competencies to their work and rank their ability to perform these competencies. Training needs generally favored clinical individual client-focused skills over prevention and public health competencies. Using scales that incorporate self-rated measures of core competency ability and importance can inform priorities for CHW training programs and contribute to successful curriculum development.
Extra-terra incognita: Martian maps in the digital age
Authors: Messeri Lisa
Published: October 2016

Science and technology studies (STS) and critical cartography are both asking questions about the ontological fixity of maps and other scientific objects. This paper examines how a group of NASA computer scientists who call themselves The Mapmakers conceptualizes and creates maps in service of different commitments. The maps under construction are those of alien Mars, produced through partnerships that NASA has established with Google and Microsoft. With the goal of bringing an experience of Mars to as many people as possible, these maps influence how we imagine our neighbouring planet. This paper analyzes two attributes of the map, evident in both its representation and the attending cartographic practices: a sense of Mars as dynamic and a desire for a democratic experience of Mars in which up-to-date Mars data can be intuitively accessed not only by scientists but by lay users as well. Whereas a democratic Mars promises users the ability to decide how to interact with the map and understand Mars, dynamic Mars imposes a more singular sense of Mars as a target of continued robotic and maybe even human exploration. Because maps of Mars have a different (and arguably less complex) set of social and political commitments than those of Earth, they help us see how different goals contradict and complement each other in matters of exploration and state-craft relevant both to other worlds and our own.
Political experiments that matter: Ordering democracy from experimental sites
Authors: Laurent Brice
Published: October 2016

Some recent work in STS has discussed various forms of ‘political experiments’. But why and how do experiments matter, and for whom? Answering these questions requires that one leave the locality of the experimental site and account for the construction of wider spaces wherein experiments matter. Using examples related to the public debate on, critique and government of nanotechnology in France, the article identifies three of these spaces. The first one is characterized by the replication of technologies of participation, the second by the conduct of radical critique, and the third by the constitution of objects of government. Overall, the description of these spaces helps describe the current (and incomplete) transformation of French democracy, as the public administration attempts to include new elements, such as ‘citizens as locals’ or ‘substances in a nanoparticulate state’, in the French polity. Thus, the study of political experiments proposed here offers analytical entry points for an examination of democratic ordering.
A study on non-linear post-buckling behavior of tapered Timoshenko beam made of functionally graded material under in-plane thermal loadings
Authors: Paul Amlan , Das Debabrata
Published: October 2016

In the present work, the non-linear post-buckling load–deflection behavior of tapered functionally graded material beam is studied for different in-plane thermal loadings. Two different thermal loadings are considered. The first one is due to the uniform temperature rise and the second one is due to the steady-state heat conduction across the beam thickness leading to non-uniform temperature rise. The governing equations are derived using the principle of minimum total potential energy employing Timoshenko beam theory. The solution is obtained by approximating the displacement fields following Ritz method. Geometric non-linearity for large post-buckling behavior is considered using von Kármán type non-linear strain-displacement relationship. Stainless steel/silicon nitride functionally graded material beam is considered with temperature-dependent material properties. The validation of the present work is successfully performed using finite element software ANSYS and using the available result in the literature. The post-buckling load–deflection behavior in non-dimensional plane is presented for different taperness parameters and also for different volume fraction indices. Normalized transverse deflection fields are presented showing the shift of the point of maximum deflection for various deflection levels. The results are new of its kind and establish benchmark for studying non-linear thermo-mechanical behavior of tapered functionally graded material beam.
Impact of static synchronous compensator on the stability of a wind farm: Case study of wind farm in Tunisia
Authors: Karoui Ridha , Aouiti Abdelkarim , Zoghlami Maha , Bacha Faouzi
Published: October 2016

The static synchronous compensator is one of the FACTS (Flexible Alternating Current Transmission System) device capable of maintaining the stability of wind turbines during a sudden default. Among these faults, the voltage drops at the connection bus wind turbines. For this fault case, the static synchronous compensator intervenes by injection of the reactive power to compensate the voltage drop. In this article, as application case, we study the wind farm of Bizerte (north of Tunisia). This farm is composed of fixed speed aero-generators using squirrel cage induction generators. Our study begins with modeling the wind system. Next, we describe the technical requirements for connection of a wind energy system to the grid and outfit at the voltage dips (low-voltage ride through) according to STEG (Tunisian Company of Electricity and Gas). We also present the structure of static synchronous compensator. Finally, we present the simulation results of the wind farm under low-voltage ride through with and without static synchronous compensator.
Functional Performance Among Active Female Soccer Players After Unilateral Primary Anterior Cruciate Ligament Reconstruction Compared With Knee-Healthy Controls
Authors: Fältström Anne , Hägglund Martin , Kvist Joanna
Published: October 2016

Background:

Good functional performance with limb symmetry is believed to be important to minimize the risk of injury after a return to pivoting and contact sports after anterior cruciate ligament reconstruction (ACLR).

Purpose:

This study aimed to investigate any side-to-side limb differences in functional performance and movement asymmetries in female soccer players with a primary unilateral anterior cruciate ligament (ACL)–reconstructed knee and to compare these players with knee-healthy controls from the same soccer teams.

Study Design:

Cross-sectional study; Level of evidence, 3.

Methods:

This study included 77 active female soccer players at a median of 18 months after ACLR (interquartile range [IQR], 14.5 months; range, 7-39 months) and 77 knee-healthy female soccer players. The mean age was 20.1 ± 2.3 years for players with an ACL-reconstructed knee and 19.5 ± 2.2 years for controls. We used a battery of tests to assess postural control (Star Excursion Balance Test) and hop performance (1-legged hop for distance, 5-jump test, and side hop). Movement asymmetries in the lower limbs and trunk were assessed with the drop vertical jump and the tuck jump using 2-dimensional analyses.

Results:

The reconstructed and uninvolved limbs did not differ in any of the tests. In the 5-jump test, players with an ACL-reconstructed knee performed worse than controls (mean 8.75 ± 1.05 m vs 9.09 ± 0.89 m; P = .034). On the drop vertical jump test, the ACL-reconstructed limb had significantly less knee valgus motion in the frontal plane (median 0.028 m [IQR, 0.049 m] vs 0.045 m [IQR, 0.043 m]; P = .004) and a lower probability of a high knee abduction moment (pKAM) (median 69.2% [IQR, 44.4%] vs 79.8% [IQR, 44.8%]; P = .043) compared with the control players’ matched limb (for leg dominance). Results showed that 9% to 49% of players in both groups performed outside recommended guidelines on the different tests. Only 14 players with an ACL-reconstructed knee (18%) and 15 controls (19%) had results that met the recommended guidelines for all 5 tests ( P = .837).

Conclusion:

The reconstructed and uninvolved limbs did not differ, and players with an ACL-reconstructed knee and controls differed only minimally on the functional performance tests, indicating similar function. It is worth noting that many players with an ACL-reconstructed knee and controls had movement asymmetries and a high pKAM pattern, which have previously been associated with an increased risk for both primary and secondary ACL injury in female athletes.
Intra-articular Steroid Injection for Frozen Shoulder: A Systematic Review and Meta-analysis of Randomized Controlled Trials With Trial Sequential Analysis
Authors: Sun Yaying , Zhang Peng , Liu Shaohua , Li Hong , Jiang Jia , Chen Shiyi , Chen Jiwu
Published: October 2016

Background:

Intra-articular steroid injection is a common intervention for frozen shoulder (FS).

Purpose:

This review aimed to illustrate the effects of intra-articular steroid injection for FS.

Study Design:

Systematic review and meta-analysis.

Methods:

PubMed, Embase, and the Cochrane Library were searched for randomized controlled trials (RCTs) comparing intra-articular steroid injection with no injection or sham injections for FS. Visual analog scale (VAS) pain scores were the primary outcome measure. Secondary outcome measures included passive external rotation, abduction, flexion, internal rotation, and functional scores. Complication rates were the safety outcome measure. Comparisons were performed with mean differences (MDs) and 95% confidence intervals (95% CIs). Three time intervals were analyzed: 4 to 6 weeks, 12 to 16 weeks, and 24 to 26 weeks postintervention. Trial sequential analysis was used to verify the pooled results. Line charts were drawn to view the recovery trend in both the intervention and control groups.

Results:

Eight RCTs with 416 patients were included. Compared with controls, patients who received intra-articular steroid injection had significantly reduced VAS pain scores at 4 to 6 weeks (MD, 1.28 cm [95% CI, 0.75 to 1.82]), 12 to 16 weeks (MD, 1.00 cm [95% CI, 0.47 to 1.52]), and 24 to 26 weeks (MD, 0.65 cm [95% CI, 0.19 to 1.10]) postinjection. Trial sequential analysis confirmed the pooled results at 4 to 6 weeks and 12 to 16 weeks but not at 24 to 26 weeks. Patients who received intra-articular steroid injection had improved passive external rotation, abduction, and flexion and Shoulder Pain and Disability Index (SPADI) scores at all 3 time intervals, as well as improved American Shoulder and Elbow Surgeons (ASES) scores at 12 to 16 weeks (MD, 12.20 [95% CI, 2.55 to 21.85]). No difference was noticed in Constant scores (MD, 5.70 [95% CI, –0.59 to 11.99]) or internal rotation except at 12 to 16 weeks (MD, 0.81° [95% CI, 0.18° to 1.44°]) and 24 to 26 weeks (MD, 3.88° [95% CI, 0.51° to 7.25°]) between steroid injection and placebo. Complication rates were 1.78% for facial flushing, 0.71% for dizziness owing to vasovagal reactions during injection, 1.07% for chest or shoulder pain, and 0.36% for nausea. Line charts improved in both groups.

Conclusion:

Intra-articular steroid injection is effective and safe for FS and relieves pain, improves functional performance, and increases range of motion. The effects are significant at 4 to 6 and 12 to 16 weeks postintervention and may last as long as 24 to 26 weeks.
Sudden sensorineural hearing loss: Is there a connection with inner ear electrolytic disorders? A literature review
Authors: Ciorba Andrea , Corazzi Virginia , Bianchini Chiara , Aimoni Claudia , Skarzynski Henryk , Skarzynski Piotr Henryk , Hatzopoulos Stavros
Published: October 2016

Electrolytic disorders of the inner ear represent a model that could be implicated in partially explaining the pathogenesis of sudden sensorineural hearing loss (SSNHL). Different types of electrolytes and different inner-ear loci are involved in cochlear homeostasis physiologically, to ensure the maintenance of an ion-balanced cochlear environment allowing a normal hair cell function. It has been hypothesized that a sudden loss of endocochlear potential, due to a rapid disruption of the inner ear fluid osmolality, could be responsible for a deterioration of the hearing function caused by damaged hair cells. The aim of this paper was to review the current literature and identify sources which might validate/fortify the hypothesis that inner ear electrolytic disorders have a role in the etiopathogenesis of SSNHL. The data in the literature underline the importance of ionic homeostasis in the inner ear, but they do not support a direct link between SSNHL and electrolyte disorders/imbalances. There is marginal evidence from otoacoustic emissions research that an indirect link might be present.
The Effectiveness of a Technology-Enhanced Flipped Science Classroom
Authors: Sezer Baris
Published: October 2016

This study examined the effect on the learning and motivation of students of a flipped classroom environment enriched with technology. A mixed research design using a pretest or posttest experimental model, combined with qualitative data, was conducted in a public middle school in Turkey for 2 weeks (three class hours) within a science course. Participants consisted of two groups of sixth-grade students. A variety of electronic materials to support a flipped classroom environment was distributed to students in the experimental group 3 days before the class. Before the normal class hour, the basic outline of the subject was discussed with the students, problem situations were created and solutions suggested, issues that were not understood were focused on, and, most importantly, student–teacher interaction was carried out at the highest level. It was determined that the flipped classroom yielded both greater academic achievement and greater motivation compared with the control group.
Tracing New Urbanism’s Suburban Intervention in Minneapolis–St. Paul
Authors: Trudeau Dan
Published: October 2016

New Urbanism (NU) is an urban planning movement that aims to curtail suburban sprawl. Critics argue that NU actually contributes to sprawl. However, such claims overlook the diverse ways in which NU is implemented. This article contributes to the study of suburban development by examining two different types of NU projects in suburban Minneapolis–St. Paul and comparing these with a control case. Using surveys of the projects’ built environments and residents’ travel behavior and attitudes toward neighbors, the article finds that the NU projects break away from the physical and functional dimensions of sprawl, yet reproduce the social dimensions.
Evolution of the structural orientation in polyacrylonitrile precursors during stabilization revealed by in-situ synchrotron wide-angle X-ray diffraction and polarized infrared spectroscopy
Authors: Zhou Yiran , Han Xu , Hu Xiaoyuan , Xu Lianghua , Cao Weiyu
Published: October 2016

Evolution of the orientation structures of polyacrylonitrile (PAN) precursors during thermal stabilization was investigated on the basis of in situ temperature-dependent measurements including synchrotron wide-angle X-ray diffraction and polarized infrared spectroscopy. The results indicated that the Hermans orientation factor of PAN crystallites increased firstly and then decreased in the process of stabilization, while the orientation of molecular chains showed a two-stage decrease. These were mainly attributed to the thermal relaxation of molecular chains and the cyclization reactions, which also resulted in the physical shrinkage as well as the chemical shrinkage apparently observed from the thermal mechanical curves of the precursor.
Multi-objective optimisation for battery electric vehicle powertrain topologies
Authors: Othaganont Pongpun , Assadian Francis , Auger Daniel J
Published: October 2016

Electric vehicles are becoming more popular in the market. To be competitive, manufacturers need to produce vehicles with a low energy consumption, a good range and an acceptable driving performance. These are dependent on the choice of components and the topology in which they are used. In a conventional gasoline vehicle, the powertrain topology is constrained to a few well-understood layouts; these typically consist of a single engine driving one axle or both axles through a multi-ratio gearbox. With electric vehicles, there is more flexibility, and the design space is relatively unexplored. In this paper, we evaluate several different topologies as follows: a traditional topology using a single electric motor driving a single axle with a fixed gear ratio; a topology using separate motors for the front axle and the rear axle, each with its own fixed gear ratio; a topology using in-wheel motors on a single axle; a four-wheel-drive topology using in-wheel motors on both axes. Multi-objective optimisation techniques are used to find the optimal component sizing for a given requirement set and to investigate the trade-offs between the energy consumption, the powertrain cost and the acceleration performance. The paper concludes with a discussion of the relative merits of the different topologies and their applicability to real-world passenger cars.
Precipitation evolution of Central Asia during the last 5000 years

Published: October 2016

Central Asia is located at the confluence of large-scale atmospheric circulation systems. However, the number of Holocene climate records is still low in most parts of this region and insufficient to allow detailed discussion and comparisons to disentangle the complex climate history and interplays between the different climatic systems. Here, we present the first stalagmite record from arid Central Asia (south-western Kyrgyzstan) by using δ18O, δ13C, and micro x-ray fluorescence (µXRF)-sulfur data spanning the last 5000 years. The cave hosting stalagmite Uluu-2 is ideally suited to identify past shifts in seasonal variations in precipitation in this part of the world. Comparison of instrumental and paleo-isotopic studies demonstrates that the Uluu-2 speleothem isotope composition faithfully records climate changes and responds to shifts in the proportion of moisture derived from mid-latitude Westerlies during the winter/spring season. The reconstructions suggest that the area was characterized by a dry climate from 4700 to 3900 yr BP, interrupted by a wet episode around 4200 yr BP. Further drier conditions also occurred between 4000 and 3500 yr BP. Wetter conditions were re-established at ca. 2500 yr BP, after another dry episode between 3000 and 2500 yr BP. With the exception of two short dry events (1150 and 1300 yr BP), the period after 1700 yr BP shows moderate to wet conditions. Regional comparisons suggest that the strength and position of the Westerly winds control climatic shifts in arid Central Asia, leading to complex local responses.

We describe here the social science-environmental health collaboration in PROTECT, the Puerto Rico Testsite for Exploring Contamination Threats, which is one of eighteen Superfund Research Program centers funded by the National Institute of Environmental Health Sciences. This collaboration has multiple facets: (1) create a holistic, unified research program that addresses the complexity of environmental contamination, (2) offer research participants an engaged and respectful interaction with the research team, (3) provide cross-training, in which the team's social scientists learn environmental health and the environmental health scientists learn social science, and (4) provide training for graduate students and post-docs in multiple disciplines in this burgeoning form of collaboration.

Published: October 2016

The purpose of the present project has been to carry out international studies on meaning-making coping among people who have been affected by cancer in a number of societies and, thereby, to try to understand the influence of culture on use of these coping methods. Five countries—Sweden, South Korea, China, Japan, and Turkey—are included in the project. Qualitative semistructured interviews have been conducted with persons with a cancer diagnosis. The research group in each country has used, as a foundation, the interview questions developed for the Swedish study. These questions were, however, modified to better suite the sociocultural context of each participating country. The results presented here concern only Turkey and are restricted to religious coping methods. The study consists of 25 cancer patients (18 females and 7 males) between 20 and 71 years of age. The results of the study in Turkey indicated that the RCOPE (Religious Coping) methods are highly relevant for the interviewees. A sociological analysis of the study made from a cultural perspective showed clearly the importance of the idea of being tolerant ( Sabr) for patients when coping with the psychological problems brought about by cancer. The study made it clear that culture plays an essential role in the choice of coping methods.

Published: October 2016

Background: In October 2010, a pharmacist-driven stewardship program was implemented at the Brigham and Women’s Hospital to ensure continued adherence to the prescribing guideline, focusing on indications for intravenous immune globulin (IVIG) use and dosing per ideal body weight. Objective: The primary objective was to describe an IVIG stewardship program at a tertiary academic medical center. Methods: This was a prospective, observational study from January 2013 through December 2014. All patients ordered to receive IVIG during the defined study period were included. The intervention assessed describes a pharmacist-driven IVIG stewardship program for medication approval. The primary end point was guideline compliance based on indication, dose, dosing weight, and frequency. Secondary end points included the number of patients receiving IVIG, indications, orders discontinued as a result of guideline nonadherence, and total amount dispensed. Results: A total of 418 patients were identified during the study time frame. The top indications were: hypogammaglobulinemia in bone marrow transplantation and hematological malignancy (50.7%), acute solid organ rejection (11.8%), and immune thrombocytopenia with bleeding (10.1%). In all, 12 patients (2.9%) received IVIG for an indication nonadherent with the IVIG prescribing guideline; 9 patients (2.2%) and 2 patients (0.5%), respectively, received a different dose or frequency per the prescribed indication; and 12 orders (2.9%) for indications nonadherent to the guideline were discontinued. A total of 26 033 g of IVIG were dispensed during the study period. Conclusions: An IVIG stewardship program, including an institution-specific prescribing guideline and a pharmacist-driven stewardship program, may ensure guideline compliance for appropriateness of indication and dose at an academic medical center.
Student-Initiated Use of Facebook for Learning Online Journalism
Authors: Song Yang
Published: October 2016

This article presents a case study of student-initiated use of Facebook Groups in doing a team project for an online journalism course. Drawing upon the concept of affinity space and a theoretical taxonomy of asynchronous online discussion, the present study triangulates classroom observation, semi-structured student interviews, and microanalysis of posting activities of a student-initiated Facebook group. The findings suggest a shift of attention from instructor-centered course design to student-initiated use of social networking sites for learning online journalism. Instructors are invited to position themselves as facilitators and to take an intersubjective stance when designing computer-assisted learning activities.
A fast massively parallel two-phase flow solver for microfluidic chip simulation
Authors: Kronbichler Martin , Diagne Ababacar , Holmgren Hanna
Published: October 2016

This work presents a parallel finite element solver of incompressible two-phase flow targeting large-scale simulations of three-dimensional dynamics in high-throughput microfluidic separation devices. The method relies on a conservative level set formulation for representing the fluid-fluid interface and uses adaptive mesh refinement on forests of octrees. An implicit time stepping with efficient block solvers for the incompressible Navier–Stokes equations discretized with Taylor–Hood and augmented Taylor–Hood finite elements is presented. A matrix-free implementation is used that reduces the solution time for the Navier–Stokes system by a factor of approximately three compared to the best matrix-based algorithms. Scalability of the chosen algorithms up to 32,768 cores and a billion degrees of freedom is shown.
Enhancing intercultural engagement through service learning and music making with Indigenous communities in Australia
Authors: Bartleet Brydie-Leigh , Sunderland Naomi , Carfoot Gavin
Published: October 2016

This article explores the potential for music making activities such as jamming, song writing, and performance to act as a medium for intercultural connection and relationship building during service learning programs with Indigenous communities in Australia. To set the context, the paper begins with an overview of current international perspectives on service learning and then moves towards a theoretical and practical discussion of how these processes, politics, and learning outcomes arise when intercultural engagement is used in service learning programs. The paper then extends this discussion to consider the ways in which shared music making can bring a sense of intercultural “proximity” that has the potential to evoke deep learning experiences for all involved in the service learning activity. These learning experiences arise from three different “facings” in the process of making music together: facing others together; facing each other; facing ourselves. In order to flesh out how these theoretical ideas work in practice, the article draws on insights and data from Queensland Conservatorium Griffith University’s award winning Winanjjikari Service Learning Program, which has been running in partnership with Barkly Regional Arts and Winanjjikari Music Centre in Tennant Creek since 2009. This program involves annual service learning trips where university music students travel to Central Australia to work alongside Aboriginal and non-Indigenous musicians and artists on a range of community-led projects. By looking at the ways in which shared music making brings participants in this program “face to face”, we explore how this proximity leads to powerful learning experiences that foster mutual appreciation, relationship building, and intercultural reconciliation.
Maternal responses to difficult food request scenarios: Relationships with feeding style and child unhealthy snack intake
Authors: Boots Samantha B , Tiggemann Marika , Corsini Nadia
Published: October 2016

This study sought to identify parent-feeding behaviours in real-life difficult feeding situations through the use of a set of scenarios. These were then used to examine links between parent feeding and child snack intake. Mothers of children aged 2–7 years ( n = 611) completed an online survey containing five snack food request scenarios, two commonly used parent-feeding scales (Restriction and Covert Control), and reported on their child’s snack intake. Results showed that parent-feeding styles (restrictive or covert) translated into specific behaviours in response to the scenarios. These parent behaviours predicted children’s intake of unhealthy snack food over and above the feeding style.
Penetrating knife injury to the skull: A case report in pediatric neurosurgical care
Authors: Cage Tene A , Sanai Nader , Lawton Michael T , Auguste Kurtis I
Published: October 2016

Isolated penetrating head injury in children is rare and is usually accidental. Each case is unique since the penetrating object and the trajectory through the brain parenchyma vary greatly among patients. We present a three-year-old girl who presented with a kitchen utility knife penetrating her left midface, skull, and brain abutting the anterior cerebral vasculature. Though the patient initially presented to a local trauma center, there were no pediatric nor vascular neurosurgeons on staff. Thus, she was transferred to our tertiary facility for definitive surgical management. A pediatric and vascular neurosurgeon worked together to remove the knife safely and the underlying vasculature remained intact. Postoperatively, the patient did well and was neurologically intact. Though penetrating cranial injury is rare in the pediatric population, such complex cases of brain injury can be properly managed with good outcome by an interdisciplinary team of specialists in tertiary care centers and can result in an excellent surgical and functional outcome for the patient.
Explicating problematic social network sites use: A review of concepts, theoretical frameworks, and future directions for communication theorizing
Authors: Lee Edmund W J , Ho Shirley S , Lwin May O
Published: October 2016

The prevalence of social network sites (SNSs) has sparked a growing interest in understanding the development of problematic SNSs use among adolescents. Yet, this nascent area of research is marked by some deficiencies in existing theoretical paradigms. This article seeks to review the state of research in problematic SNSs use—broadly with a specific focus on adolescents—and identify key areas of research for future scholarly work. First, we summarize the historical and recent developments of media addiction and problematic SNSs use research. Second, we discuss the theoretical perspectives that contribute to our understanding of the problematic SNSs use phenomenon and identify the weaknesses of these frameworks. Third, we propose that communication scholars should strive for theoretical integration and examine the impact of microsystem (e.g. parents and peers) and macrosystem (e.g. surveillance culture) on the development of problematic SNSs among adolescents. Directions for future theoretical and methodological approaches are suggested.
