Synthesis and characterization of fluorescein-grafted polyurethane for potential application in biomedical tracing
Authors: Yang Boyuan , Zou Qin , Lin Lili , Li Limei , Zuo Yi , Li Yubao
Published: December 2016

Redesigned multifunctional biopolymers represent a novel building bridge for interdisciplinary collaborations in biomaterials development. We prepared fluorescein-grafted polyurethane scaffolds (PU-C1, PU-C5, and PU-B1) to meet both clinical needs and biological safety evaluations, using different contents of calcein and different synthesis procedures for potential biomedical tracing. X-ray diffraction, infrared, X-ray photoelectron spectroscopy, nuclear magnetic resonance, scanning electron microscopy, and light microscopy were used to analyze the composition and structure of polyurethanes, as well as to observe their morphology with and without biomarkers. Fluorescence spectrophotometer and fluorescence microscopy were used to detect the fluorescence characteristics. The results showed that the grafting of calcein significantly affected the chemical structure and fluorescence sensitivities of copolymers. When compared to calcein, which was added before synthesis (PU-C1), the marker that was added during the extender process (PU-B1) presented higher fluorescence efficiency. Both PU-C5 and PU-B1 exhibited strong fluorescent response and good cytocompatibility in vitro and in vivo, with no interference from the autofluorescence of tissues after 4 weeks of implantation. The fluorescence-marked material can be used to continuously and noninvasively monitor the dynamic changes in polymers, which provides a way to clearly trace the material or to distinguish between the material and tissue in vivo.

Authors: Wang Qiushi , Ning Haibin , Vaidya Uday , Pillay Selvum , Nolen Leigh-Ann
Published: December 2016

Carbon fiber–reinforced thermoplastic composites are gaining increasing interest in various applications thanks to their combined properties of high specific stiffness, high specific strength, and superior toughness. Their mechanical properties are highly dependent on the carbon fiber content. In this study, the carbonization-in-nitrogen method (CIN) developed in previous work is used to measure the fiber content of carbon fiber thermoplastic composites. Three types of carbon fiber thermoplastic composite samples were prepared using hot-melt impregnation. The carbon fiber thermoplastic composite sample is carbonized in a nitrogen environment alongside a neat resin sample that is used for calibrating the resin carbonization percentage. A good agreement is achieved between the nominal carbon fiber content and the carbon fiber content measured using the CIN method. It is concluded that the CIN method is an accurate and efficient way to characterize the carbon fiber content for carbon fiber thermoplastic composites. This work completes the verification of the CIN method, which enables extended application to thermoplastic composites. Moreover, it has its unique merits on evaluating the carbon fiber content for high-temperature and solvent-resistant thermoplastic composites that would encounter challenges using other methods.
Preschool girls as rule breakers: Negotiating moral orders of justice and fairness
Authors: Karlsson Magnus , Hjörne Eva , Evaldsson Ann-Carita
Published: December 2016

This study examines how preschool girls organize situated board games. Examining video data using an ethnomethodological approach, we focus on moral work-in-interaction in instances where the girls negotiate rule violations. It was found that the girls oriented to diverse forms of moral orders, shifting between a competitive/justice-based order and a socio-moral order of reciprocal relations. Argumentative moves of cheating were used as communicative resources both to control moral transgressions and to gain personal advantages. Overall, the analysis shows that preschool girls are active moral agents in the making and breaking of rules and in the negotiation of complex moral orders.
Improved interfacial shear strength of carbon fiber/polyphenylene sulfide composites by graphene
Authors: Xu Junyi , Xu Dongxia , Wang Xiaojun , Long Shengru , Yang Jie
Published: December 2016

By taking advantage of the micrometer size dimensions and excellent mechanical properties along with the large specific surface area of graphene (GN) sheet, we developed a simple and effective strategy to improve the interfacial properties of carbon fiber (CF)-reinforced plastic. Different contents of GN dispersed in the agent were introduced onto the surface of CF to prepare the CF-GN/polyphenylene sulfide composites. The surface topography and the distribution of GN sheets on the surface of CF were detected by scanning electron microscopy. It was found that the introduction of GN significantly increased the surface roughness of CF, which was beneficial to enhance mechanical interlocking between the fiber and matrix. The microbond test showed that there was the most appropriate GN content, at which the composites exhibited the highest interfacial shear strength (IFSS). An improvement of 20% from 55.2 MPa to 66.2 MPa in IFSS confirmed the remarkable improvement in the interfacial properties of the composites when only 0.5 wt% of GN sheets was introduced in the agent sizing.
‘For a living countryside’: Political rhetoric about Swedish rural areas
Authors: Nilsson Bo , Lundgren Anna Sofia
Published: December 2016

The expression ‘a living countryside’ is often used to characterize the goal of Swedish rural politics. In this article the use of the expression in 170 non-government bills related to Swedish rural politics is analysed using discourse theory. On a general level, the expression was found to be empty of meaning and open for use by different and often opposing political parties proposing different and sometimes antagonistic measures. However, there were aspects of it that flirted with positively charged notions of Swedish national identity. It was also clear that the discursive struggle for a living countryside was also part of a party-political struggle. Further, the fantasy of a living countryside performed an ideological function in that it under-communicated how rural areas are generally and structurally subordinated to urban centres in ways that reach far beyond easily performed measures and political party quarrels.
On being ‘head strong’: The pain zone and concussion in non-elite rugby union
Authors: Liston Katie , McDowell Mark , Malcolm Dominic , Scott-Bell Andrea , Waddington Ivan
Published: December 2016

In recent years there has been growing concern about concussion in sport in general and rugby union in particular. The qualitative study reported here draws on interviews ( n=20) with adult players in non-elite club rugby union in Ireland in order to explore the frames of reference within which they perceive, give meaning to and manage concussion. Within a sporting subculture which emphasizes lay sporting values – particularly the value of ‘playing hurt’ – and which reflects a functional view of injury, non-elite players tend to display an irreverent attitude towards concussion which encourages risky behaviours and underplays, ignores or denies the significance of concussion. We analogously describe these beliefs and actions as being ‘head strong’. The paper concludes by identifying the contextual contingencies which make the regulation of injuries in rugby union so difficult and by establishing some core principles of public health education campaigns that might be deployed to militate against the high incidence of concussive injury in future.
Nonprofit Collections of Digital Personal Experience Narratives
Authors: Dush Lisa
Published: December 2016

Nonprofit organizations have long used the personal experience narratives of clients, staff, and stakeholders in their communications. This study explores digital-age practices with this text form, analyzing 82 collections of digital personal experience narratives (DPENs) housed at or linked to Web sites of nonprofit organizations. Results are reported on the variety and frequency of the modes, featured constituencies, narrative perspectives, and digital interface features in the sample. Overall, the nonprofit DPEN collections sampled showed limited use of new digital production and distribution possibilities. Practice, however, differed notably between two segments of nonprofits: networks and service organizations. To explore these results, the article discusses key examples of DPEN collections from each segment.
Self-Determined Learning to Motivate Struggling Learners in Reading and Writing
Authors: Wehmeyer Michael L. , Shogren Karrie A. , Toste Jessica R. , Mahal Stephanie
Published: December 2016

Promoting self-determined learning through student-directed learning strategies has been documented to promote more positive school-related outcomes for upper elementary grade learners with disabilities and other students who are struggling. These strategies are typically introduced in multicomponent interventions combining several student-directed learning strategies such as self-monitoring, self-evaluation, antecedent cue regulation, and self-instruction. Such interventions have established efficacy in promoting a wide array of academic outcomes. Students’ motivation is consistently related to academic achievement, but it has been found to change over time, with intrinsic motivation’s having marked decreases into the later elementary years and into middle school. This article reviews the literature on the impact of promoting self-determination and self-determined learning strategies that can be used to promote more positive reading and writing outcomes to enable students to become autonomous learners.
Reading and Writing Instruction in the Upper Elementary Grades
Authors: Toste Jessica R. , Ciullo Stephen
Published: December 2016

This special issue of Intervention in School and Clinic supports the knowledge and skills of educators who provide reading and writing intervention to students with learning disabilities (LD) in the upper elementary grades. Grades 3 through 5 are critical to long-term academic success because, for many students with LD, foundational literacy skills are still developing during a time when reading and writing tasks become more challenging. In this issue, evidence-based instructional practices and strategies are presented. The articles in this issue include interventions for improving word reading skills, written expression, advanced reading comprehension, as well as motivation and self-determined learning. Detailed teaching steps, classroom examples, and suggestions for classroom resources are included.
Using the De Jong Gierveld Loneliness Scale With Early Adolescents: Factor Structure, Reliability, Stability, and External Validity
Authors: Grygiel Paweł , Humenny Grzegorz , Rębisz Sławomir
Published: December 2016

The present investigation is the first examination of the factor structures, reliability, external validity, longitudinal invariance, and stability of the De Jong Gierveld Loneliness Scale (DJGLS), as used with early adolescents. It is based on a two-wave, large, representative sample of Polish primary school pupils. The results demonstrate that the model most reflective of the factor structure of the DJGLS is the bifactor model, which assumes the occurrence of one, highly reliable, general factor (overall sense of loneliness) and two, relatively irrelevant, subfactors. Essential unidimensionality (the general factor accounting for three fourth of the common variance) suggest that the interpretation of the subfactors over and above the general factor is inappropriate. The longitudinal confirmatory factor analysis indicated that the bifactor structure of the DJGLS is invariant over time. Correlations with self-rated loneliness, sociometric acceptance/rejection, social self-efficacy, identification with class group, family structure, and gender provide support for the validity of the DJGLS. This implies that it could be used as a measure of loneliness in adolescence, which does not involve references to the school context, making it possible to conduct studies that go beyond school period and compare the intensity of the feeling of loneliness in that group with other age groups.
Practice to Evidence: Using Evaluability Assessment to Generate Practice-Based Evidence in Rural South Georgia
Authors: Honeycutt Sally , Hermstad April , Carvalho Michelle L. , Arriola Kimberly R. Jacob , Ballard Denise , Escoffery Cam , Kegler Michelle C.
Published: December 2016

Evidence from formal evaluation of real-world practice can address gaps in the public health knowledge base and provide information about feasible, relevant strategies for varied settings. Interest in evaluability assessment (EA) as an approach for generating practice-based evidence has grown. EA has been central to several structured assessment processes that identify and select promising programs and evaluate those most likely to produce useful findings. The Emory Prevention Research Center used EA as part of an initiative to generate practice-based evidence for cancer prevention in southwest Georgia. Our initiative consisted of five steps: (1) environmental scan to identify potential programs, (2) program selection, (3) EA, (4) evaluation, and (5) dissemination. We identified nine programs, four of which completed a formal application, and conducted two EAs. EAs consisted of document review, site visits, and literature reviews. The EA purpose was to assess the program model, data availability, stakeholder interest in evaluation, feasibility of an outcome evaluation, and potential contribution to the literature. We conducted one outcome evaluation and one descriptive qualitative study; both were published in peer-reviewed journals. The outcome evaluation addressed knowledge gaps about strategies to promote colorectal cancer screening. Results led to the program’s inclusion in national resources for practitioners seeking evidence-based practices and helped the community organization expand and strengthen the program. As part of a structured assessment process, EA can identify programs most likely to produce useful results for dissemination and is a viable approach for local initiatives to generate practice-based evidence in rural or low-resource settings.
The map as playground: Location-based games as cartographical practices
Authors: Lammes Sybille , Wilmott Clancy
Published: December 2016

This article examines how maps in location-based mobile games are used as surfaces on which players can inscribe their whereabouts and other local information while being on the move. Using different examples of location-based games (LBGs) to which the map is central, our main argument is that such cartographical LBGs foreground the fluidity of mapping and emphasize the performative aspects of playing with maps. As such, we wish to move away from a conception of maps as representational texts and will show that it is far more productive to approach such cartographical games as processual and navigational practices. Instead of conceiving maps in such games as ‘mimetic interfaces’ (Juul, 2009), they should therefore be approached as what we will call navigational interfaces. To understand them as such, we will combine perspectives from game studies with non-representational understandings of maps as technological and spatial practices as developed in human geography and science and technology studies. By doing so, we wish to instigate a productive interdisciplinary debate about the relation between play and mapping as to deepen our understanding of LBGs as cultural cartographical practices.
Is there a bilingual advantage in phonetic and phonological acquisition? The initial learning of word-final coronal stop realization in a novel accent of English
Authors: Spinu Laura E , Hwang Jiwon , Lohmann Renata
Published: December 2016

Research question:

We address the question of whether the cognitive advantage of the bilingual mind, already demonstrated in the case of auditory processing or novel word acquisition, also applies to other linguistic domains, specifically to phonetic and phonological learning.

Design:

We compare the performance of 17 monolinguals and 25 bilinguals from Canada in a production experiment with two tasks: imitation and spontaneous reproduction of a novel foreign accent, specifically Sussex English.

Data and analysis:

To eliminate potential sources of variability, our focus is on a sound already existing in the subjects’ production (the glottal stop), but differently mapped to surface representations in the novel accent to which they were exposed (i.e., as an allophone of coronal stops in word-final position). We measured the glottal stop rates of our subjects in baseline, training, and post-training.

Results:

The two groups behaved differently, with bilinguals showing a larger increase of their glottal stop rate post-training. Our results are thus consistent with a bilingual advantage in phonetic and phonological learning.

Originality:

We interpret these findings in light of recent psycholinguistic work and conclude that echoic memory strategies, possibly underlain by stronger subcortical encoding of sound in bilinguals, may account for our results by facilitating the re-mapping between existing mental representations of sounds and existing articulatory command configurations.

Significance:

Our study adds to the body of work suggesting that there may be an advantage of bilingualism in second dialect learning in adulthood, and provides an explanation in terms of perceptual strategies in which echoic memory is involved. We also contribute to the body of research suggesting that imitation of an action can result in improved understanding of that action.
In search of the working memory advantage in conference interpreting – Training, experience and task effects
Authors: Chmiel Agnieszka
Published: December 2016

Aims and Objectives:

The purpose of the study was to disentangle the effects of simultaneous interpreting experience and training on working memory, to examine the effect of language, modality and recall on working memory scores, and to associate memory scores of trainees with interpreting quality.

Design:

Working memory scores were compared in the L2 reading span task (performed by professional conference interpreters, bilingual controls and interpreter trainees tested before and after training) and in the L1 reading span task and L1 listening span task (performed by interpreters and controls).

Data and Analysis:

Data was collected from 68 participants in experiment 1 and from 51 participants in experiment 2. It was analysed by means of linear models, regressions and t-tests.

Findings:

Professional interpreters consistently outperformed controls on all working memory tasks. They performed better in L1 than L2, and their scores were not affected due to modality (visual vs. auditory presentation) and recall mode (serial vs. free). Interpreter training improved working memory scores. Trainees’ higher scores predicted better interpreting performance.

Originality:

This was the first study to adopt a longitudinal design to examine the effect of training on memory of conference interpreter trainees.

Significance:

The study shows that interpreter training (but not experience) improves working memory capacity and predicts interpreting performance.
The meaning of exile
Authors: Hess Andreas
Published: December 2016

This article discusses why the theme of exile, marginality and the role of outsiders occupied Judith N. Shklar and how it impacted on her teaching and writing. More specifically it draws on Shklar’s last Harvard lectures and essays in which she reflects systematically on the questions of obligation and exile. It maintains that the relatively late turn towards exile is neither accident nor retrospective construction. Throughout her adult life Judith Shklar argued from a position of ‘optimal marginality’ – what has been called ‘exile from exile’ − that allowed her to situate and present herself simultaneously as an outsider and to present her political theory as a kind of pedagogic and maieutic discourse. This was a way of turning traumatic personal experiences into a creative academic performance marked by true intellectual curiosity.
Managing police personnel for effective crime control in Nigeria
Authors: Chinwokwu Eke Chijioke
Published: December 2016

This study examines the ways in which police authorities manage their personnel, as well as the factors militating against police authorities in managing their personnel for effective crime control and prevention in Nigeria. The study used both quantitative and qualitative designs to attempt to identify the criteria used in posting police officers. Data were obtained through questionnaires from 360 randomly selected respondents complemented by 15 in-depth interviews (IDI) undertaken in three geo-political regions in Nigeria namely: southeast, southwest and north central. The three geo-political regions were purposively chosen based on the incidences of armed robbery recorded in each. The study also used secondary data sourced from the National Bureau of Statistics and the Nigeria Police Force as reference materials. Simple percentages and chi-squared tests were employed to analyse the collected data. The qualitative data were content analysed. The findings revealed that factors such as crime rate, population size, industrial development and land mass or political interference were not clearly defined criteria used in the posting of personnel. The number of police in a region does not equate to more or less crime; effective crime control and prevention depend on proper and effective utilization, as well as management, of police personnel. Police authorities are culpable of mismanagement of police personnel for personal gain to the detriment of citizens; most states are under-policed and under-staffed. This study also found that factors militating against the effective utilization and management of police personnel include: corruption, political interference, ethno-religious consideration, lack of funds and lack of facilities. Thus, the study recommends among other things, that the distribution of police personnel should be anchored to the population size, industrialization and volume of criminality in a particular place; there should be a gross reduction in the numbers of personnel attached to political officials, whereas those attached to individuals who are not entitled to personal police protection must be withdrawn and efforts made to recruit more people into the police force.
Unscrambling method and methodology in action research traditions: theoretical conceptualization of praxis and emancipation
Authors: Cordeiro Luciana , Soares Cassia Baldini , Rittenmeyer Leslie
Published: December 2016

Action research is a participatory approach that is used in an array of contexts. From its first proposition it comprises four core principles: participation and collaboration; a constant spiral cycle of self-reflection; knowledge generation; and practice transformation. Praxis and emancipation are two important analytical categories in AR, but are conceptualized differently in the two existing AR traditions. These conceptualizations reveal different AR aims, which lead to either the use of AR as a method (Northern tradition) or as a methodology (Southern tradition). Much depends on the researchers’ interest and worldview. Our objective in this paper is to compare how emancipation and praxis are theorized in both traditions. This discussion intends to add insight into the methodological understanding and utilization of AR.
Criteria for quality in qualitative research and use of freedom of information requests in the social sciences
Authors: Walby Kevin , Luscombe Alex
Published: December 2016

Access to information (ATI) and freedom of information (FOI) requests are an under-used means of producing data in the social sciences, especially across Canada and the United States. We use literature on criteria for quality in qualitative inquiry to enhance ongoing debates and developments in ATI/FOI research, and to extend literature on quality in qualitative inquiry. We do this by building on Tracy’s (2010) article on criteria for quality in qualitative inquiry, which advances meaningful terms of reference for qualitative researchers to use in improving the quality of their work; and illustrating these criteria using examples of ATI/FOI research from our own work and from others’ in Canada, the United States, and the United Kingdom. We argue that, when systematically designed and conducted, ATI/FOI research can prove extraordinary in all eight of Tracy’s criteria.
Machine-made lace, the spaces of skilled practices and the paradoxes of contemporary craft production
Authors: Fisher Tom , Botticello Julie
Published: December 2016

This article inspects a set of paradoxes that appeared in an investigation of contemporary industrial craft in the last remaining factory making machine lace in the United Kingdom. Its focus on a single site, set against a now global industry, means it can build on work in cultural and economic geography to understand this setting as a heterogeneous space, with links to a range of material and immaterial lineages, practices and networks. Ethnographic fieldwork on the factory floor at Cluny Lace threw up three paradoxes inherent in the firm’s continued survival in a context of industrial decline. The first of these paradoxes is the re-concentration of material and immaterial resources in the factory both despite and as a result of the global restructuring of the textile industry. The second is the embodiment of knowledge, and therefore craft skill, both within persons and distributed through the worker’s material environments. Third, is the recognition that the skilled practice the workers carry is not uniform but is multiple, resulting from an unequal distribution of opportunities within the lace industry and different versions of practice that result from the re-concentration of human capital in the factory. This article demonstrates that skill is not uncontested, but is power-ridden and value-laden, and transcends scale. It shows that knowledge and skill are not bound within an individual but are distributed among social actors, material objects and locales, where an attention to each is necessary for understanding the spaces of skilled practices and the ongoing survival of contemporary industrial craft production.
Optimisation of machine components in thermal bonding process of nonwovens: Effect of the conveyer belt on the porous web performance
Authors: Peksen M , Acar M , Malalasekera W
Published: December 2016

A complementary study to our previous research to aid in the optimisation of the thermal bonding machine components for improved thermally bonded nonwoven production is introduced. The effect of the conveyer belt on the nonwoven’s thermo-fluid flow behaviour is investigated in detail. A hybrid model consisting of the discrete conveyer belt geometry and the continuum porous nonwoven web, is presented. A comparison study to predict the thermal and flow field differences in 3D and 2D formulations of the same problem is elucidated. The thermal and fluid flow distributions within the conveyer belt, nonwoven and the air domain are predicted with particular focus on the conveyer belt component of the Low & BONAR pilot machine. It has been shown that the developed 2D model provides accurate results for the conveyer belt temperatures. The three-dimensional flow effects on the thermal boundary have been predicted. The 3D approach is shown to be superior in depicting the wake behind the central conveyer belt thread. The amplitude of the wavy geometry is determined to be introducing different degrees of geometric three dimensionalities in the wake. The industrial partner Low & BONAR (former COLBOND bv.) provided technical data for the nonwoven and machine components.
Posture-Dependent Corticomotor Excitability Differs Between the Transferred Biceps in Individuals With Tetraplegia and the Biceps of Nonimpaired Individuals

Published: December 2016

Background. Following biceps transfer to enable elbow extension in individuals with tetraplegia, motor re-education may be facilitated by greater corticomotor excitability. Arm posture modulates corticomotor excitability of the nonimpaired biceps. If arm posture also modulates excitability of the transferred biceps, posture may aid in motor re-education. Objective. Our objective was to determine whether multi-joint arm posture affects corticomotor excitability of the transferred biceps similar to the nonimpaired biceps. We also aimed to determine whether corticomotor excitability of the transferred biceps is related to elbow extension strength and muscle length. Methods. Corticomotor excitability was assessed in 7 arms of individuals with tetraplegia and biceps transfer using transcranial magnetic stimulation and compared to biceps excitability of nonimpaired individuals. Single-pulse transcranial magnetic stimulation was delivered to the motor cortex with the arm in functional postures at rest. Motor-evoked potential amplitude was recorded via surface electromyography. Elbow moment was recorded during maximum isometric extension trials, and muscle length was estimated using a biomechanical model. Results. Arm posture modulated corticomotor excitability of the transferred biceps differently than the nonimpaired biceps. Elbow extension strength was positively related and muscle length was unrelated, respectively, to motor-evoked potential amplitude across the arms with biceps transfer. Conclusions. Corticomotor excitability of the transferred biceps is modulated by arm posture and may contribute to strength outcomes after tendon transfer. Future work should determine whether modulating corticomotor excitability via posture promotes motor re-education during the rehabilitative period following surgery.
Sex and Race/Ethnicity Differences in Following Dietary and Exercise Recommendations for U.S. Representative Sample of Adults With Type 2 Diabetes
Authors: Vaccaro Joan A. , Huffman Fatma G.
Published: December 2016

This study examined sex by race/ethnicity differences in medical advice received for diet and exercise with corresponding health behaviors of a U.S. representative sample of adults with type 2 diabetes ( N = 1,269). Data from the National Health and Nutrition Examination Surveys for 2011-2014 for 185 Mexican Americans, 123 Other Hispanics, 392 non-Hispanic Blacks, 140 non-Hispanic Asians, and 429 non-Hispanic Whites were analyzed using logistic regression analyses. Reporting being given dietary and exercise advice was positively associated with reporting following the behavior. There were differences in sex and sex by race/ethnicity for reporting receiving medical advice and performing the advised health behavior. These results suggest the importance of physicians having patient-centered communication skills and cultural competency when discussing diabetes management.
Mental Health Among Jail and Prison Inmates
Authors: Yi Youngmin , Turney Kristin , Wildeman Christopher
Published: December 2016

Previous studies provide insight into the mental health of jail and prison inmates, but this research does not compare the two groups of inmates. Using data from the Fragile Families and Child Wellbeing Study, this article examines how the association between incarceration and self-reported mental health varies by facility type, net of an array of demographic and socioeconomic characteristics. Both jail and prison inmates report high rates of depression, life dissatisfaction, heavy drinking, and illicit drug use. In adjusted logistic regression models, those incarcerated in jails, compared with those not incarcerated, have higher odds of depression (odds ratio [ OR] = 5.06, 90% confidence interval [CI; 1.96, 13.11]), life dissatisfaction ( OR = 3.59, 90% CI [1.40, 9.24]), and recent illicit drug use ( OR = 4.03, 90% CI [1.49, 10.58]). Those incarcerated in prisons have higher odds of life dissatisfaction ( OR = 3.88, 90% CI [2.16, 6.94]) and lower odds of recent heavy drinking ( OR = 0.32, 90% CI [0.13, 0.81]) compared with those not incarcerated. Furthermore, jail inmates report significantly more depression, heavy drinking, and illicit drug use than prison inmates. These results suggest the association between incarceration and mental health may vary substantially across facilities and highlight the importance of expanding research in this area beyond studies of prisons. The results also indicate that public health professionals in the correctional system should be especially attuned to the disproportionately high levels of poor mental health outcomes among jail inmates.
An English geography curriculum abroad: Using ‘third space’ as an ideal type to understand similarity and difference
Authors: Chapman Kay
Published: December 2016

Where there is a demand for English-medium schooling and English academic qualifications in a former British colony such as Sri Lanka, questions about power relations and the construction of knowledge are raised. Geography is a school subject that claims to make sense of the world. In this article I propose a postcolonial theoretical framework and the concept of third space as an ideal type to compare with interaction in the pedagogical third space of geography classrooms where the syllabus is from a colonial epistemology, teachers may be local or British expatriate and pupils are from affluent families desirous of an English education. This comparison will help further our understanding of how and what kind of geographical knowledge of difference and similarity is constructed through interaction between the syllabus, pupils and teachers in geography classrooms in British international schools.
Constructing memories of Holmfirth through Last of the Summer Wine
Authors: Hibberd Lynne , Tew-Thompson Zoë
Published: December 2016

Last of the Summer Wine (BBC, 1973–2010) was filmed in Holmfirth, West Yorkshire, UK, for 37 years. Consequently, it has affected collective memories of the space and place of the region. Summer Wine has become embedded into the area and exists as part of everyday communicative memory in which fictional representations, oral histories, embodied practices, sensory engagements and lived experiences collide. In examining Summer Wine’s continued presence in Holmfirth even after it has ceased production, we investigate how the series as a text, institution and brand serves to spatially inform Holmfirth and construct, embed and inform cultural memory.
Medium- to long-term outcomes of anatomical reconstruction of the radioulnar ligament to the ulnar fovea
Authors: Nakamura T. , Abe K. , Nishiwaki M. , Iwamoto T. , Sato K.
Published: December 2016

We examined the medium- to long-term outcome of the original reconstruction technique of the radioulnar ligament using a half-slip of the extensor carpi ulnaris tendon for chronic foveal avulsion of the triangular fibrocartilage complex. We treated 37 wrists in 36 patients with a minimum follow-up of 5 years. Of 36 patients, 12 had more than 10 years follow-up. At final follow-up, 30 patients (31 wrists) reported no pain, five patients (five wrists) reported mild occasional pain and one patient reported severe persistent pain. Two patients had lost 30° of supination. Complete stability of the distal radio-ulnar joint was achieved in 31 wrists, moderate instability was noted in five and severe distal radio-ulnar joint instability remained in one. The size of the bone tunnel was assessed radiologically: in two it had enlarged; in 23 it was unchanged; and in 12 it appeared to have closed over the tendon graft. The overall clinical outcomes were 28 excellent, four good, four fair and one poor. The 12 wrists with more than 10 years follow-up had seven excellent, three good and two fair clinical results. This reattachment technique appears to work and last over the medium- to long-term.

Published: December 2016

Sepsis is a life-threatening event predominantly caused by Gram-negative bacteria. Bacterial infection causes a pronounced macrophage (MΦ) and dendritic cell activation that leads to excessive pro-inflammatory cytokine IL-1β, IL-6 and TNF-α production (cytokine storm), resulting in endotoxic shock. Previous experimental studies have revealed that inhibiting NF-κB signaling ameliorates disease symptoms; however, the contribution of myeloid p65 in endotoxic shock remains elusive. In this study, we demonstrate increased mortality in mice lacking p65 in the myeloid lineage (p65Δmye) compared with wild type mice upon ultra-pure LPS challenge. We show that increased susceptibility to LPS-induced shock was associated with elevated serum level of IL-1β and IL-6. Mechanistic analyses revealed that LPS-induced pro-inflammatory cytokine production was ameliorated in p65-deficient bone marrow-derived MΦs; however, p65-deficient ‘activated’ peritoneal MΦs exhibited elevated IL-1β and IL-6. We show that the elevated pro-inflammatory cytokine secretion was due, in part, to increased accumulation of IL-1β mRNA and protein in activated inflammatory MΦs. The increased IL-1β was linked with heightened binding of PU.1 and CCAAT/enhancer binding protein-β to Il1b and Il6 promoters in activated inflammatory MΦs. Our data provide insight into a role for NF-κB in the negative regulation of pro-inflammatory cytokines in myeloid cells.
Development of Type 2 Diabetes Mellitus Phenotyping Framework Using Expert Knowledge and Machine Learning Approach
Authors: Kagawa Rina , Kawazoe Yoshimasa , Ida Yusuke , Shinohara Emiko , Tanaka Katsuya , Imai Takeshi , Ohe Kazuhiko
Published: December 2016

Background:

Phenotyping is an automated technique that can be used to distinguish patients based on electronic health records. To improve the quality of medical care and advance type 2 diabetes mellitus (T2DM) research, the demand for T2DM phenotyping has been increasing. Some existing phenotyping algorithms are not sufficiently accurate for screening or identifying clinical research subjects.

Objective:

We propose a practical phenotyping framework using both expert knowledge and a machine learning approach to develop 2 phenotyping algorithms: one is for screening; the other is for identifying research subjects.

Methods:

We employ expert knowledge as rules to exclude obvious control patients and machine learning to increase accuracy for complicated patients. We developed phenotyping algorithms on the basis of our framework and performed binary classification to determine whether a patient has T2DM. To facilitate development of practical phenotyping algorithms, this study introduces new evaluation metrics: area under the precision-sensitivity curve (AUPS) with a high sensitivity and AUPS with a high positive predictive value.

Results:

The proposed phenotyping algorithms based on our framework show higher performance than baseline algorithms. Our proposed framework can be used to develop 2 types of phenotyping algorithms depending on the tuning approach: one for screening, the other for identifying research subjects.

Conclusions:

We develop a novel phenotyping framework that can be easily implemented on the basis of proper evaluation metrics, which are in accordance with users’ objectives. The phenotyping algorithms based on our framework are useful for extraction of T2DM patients in retrospective studies.
Why Does Nonsuicidal Self-Injury Improve Mood? A Preliminary Test of Three Hypotheses
Authors: Fox Kathryn R. , Toole Kaitlyn E. , Franklin Joseph C. , Hooley Jill M.
Published: December 2016

People who engage in nonsuicidal self-injury (NSSI) often state that it helps them feel better. We tested three hypotheses through which this mood modification might occur. Following a negative mood induction, adults reporting past year NSSI were randomized into a control (i.e., sitting alone quietly), mild distraction, or pain condition. All participants completed mood ratings at regular intervals. No mood repair occurred in the control condition. However, distraction improved mood both during and after the activity. Participants who self-administered pain reported no overall mood change, suggesting that contrary to popular NSSI theories, pain likely does not improve mood via distraction. However, as predicted, level of self-criticism moderated mood change during pain. Participants high on self-criticism felt significantly better during pain and participants low on self-criticism felt significantly worse during pain. Findings shed light on how NSSI improves mood by clarifying the circumstances under which different affect regulation processes may operate.
Anti-Americanism in East Asia: Analyses of college students’ attitudes in China, Japan, and South Korea
Authors: Kim Young Choul , Yoo Ho Keun
Published: December 2016

In the last decade, negative attitudes towards the United States have increased throughout the world. Though the United States and East Asian countries have relatively had harmonious relationships, anti-Americanism is still prevalent for various reasons. In spite of China’s increasing economic interdependence with the United States, the country is succeeding to its long history of anti-Americanism. Although Japan and South Korea have been considered pro-United States allies since the Korean War (1950–1953), the countries’ younger generations have often expressed critical opinions of the United States. What is the cause of this anti-American sentiment in the East Asian countries? The purpose of this study is to examine the determinants of anti-American sentiment in East Asian countries using a cross-national survey. The results of the empirical analyses support previous approaches and promote four theoretical concepts: (1) the people’s knowledge and curiosity about the United States is the most influential factor of anti-American sentiment for East Asian college students (the cognitive-orientation); (2) individual’s attitudes towards American culture and society influence anti-American sentiment in East Asian countries (the cultural-cleavage); (3) anti-American sentiment in East Asian countries is mostly affected by people’s general ideas about the roles of the United States in the world and United States’ foreign policies (the anti-hegemony); and (4) the people’s general perception on the relationship between their own countries and the United States is another determinant of anti-American sentiment in East Asian countries (the equal-relationship). In contrast, it explains that gender and the financial condition of East Asian college students are not significant determinants of anti-American sentiment.
Lazy thinking, lazy giving? Examining the effects of Norwegian aid on forests in developing countries
Authors: Hermanrud Kristine , de Soysa Indra
Published: December 2016

The Norwegian government enthusiastically supports the protection of forests, which are important CO2sinks. Given all the difficulty surrounding the reduction of greenhouse gases, funding the protection of forests is a sound proposition. Up to the present time, how well has Norwegian aid to forests and Norwegian bilateral aid affected the health of forests? Using World Bank data on forest degradation and change in forest area for roughly 130 developing countries from 1999 to 2013, we find that higher levels of Norwegian forest aid among recipient countries has generally had no effect on reducing degradation, while total Norwegian bilateral aid is associated with increased degradation, results that might very well be causal because they are robust to estimations using instrumental variable techniques. Two-step selection models show that forest aid also increases forest degradation, result that are quite unflattering of Norwegian aid. These results are robust to several alternative specifications of our models and to alternative estimation techniques including country fixed effects. Two clear lessons emerge from our findings; firstly, that Norwegian aid does not seem to be coordinated for addressing the problem of forest degradation; and secondly, aid as a means to solve the climate problem likely faces steep obstacles if even a non-strategic, aid-giving country, such as Norway, is capable of more harm than good.

Background

Traumatic pancreatic injuries are rare, and guidelines specifying management are controversial and difficult to apply in the acute clinical setting. Due to sparse data on these injuries, we carried out a retrospective review to determine outcomes following surgical or non-surgical management of traumatic pancreatic injuries. We hypothesize a higher morbidity and mortality rate in patients treated surgically when compared to patients treated non-surgically.

Methods

We performed a retrospective review of data from four trauma centers in New York from 1990–2014, comparing patients who had blunt traumatic pancreatic injuries who were managed operatively to those managed non-operatively. We compared continuous variables using the Mann-Whitney U test and categorical variables using the chi-square and Fisher’s exact tests. Univariate analysis was performed to determine the possible confounding factors associated with mortality in both treatment groups.

Results

Twenty nine patients were managed operatively and 32 non-operatively. There was a significant difference between the operative and non-operative groups in median age (37.0 vs. 16.2 years, P = 0.016), grade of pancreatic injury (grade I; 30.8 vs. 85.2%, P value for all comparisons <0.0001), median injury severity score (ISS) (16.0 vs. 4.0, P = 0.002), blood transfusion (55.2 vs. 15.6%, P = 0.0012), other abdominal injuries (79.3 vs. 38.7%, P = 0.0014), pelvic fractures (17.2 vs. 0.00%, P = 0.020), intensive care unit (ICU) admission (86.2 vs. 50.0%, P = 0.003), median length of stay (LOS) (16.0 vs. 4.0 days, P <0.0001), and mortality (27.6 vs. 3.1%, P = 0.010).

Conclusions

Patients with traumatic pancreatic injuries treated operatively were more severely injured and suffered greater complications than those treated non-operatively. The greater morbidity and mortality associated with these patients warrants further study to determine optimal triage strategies and which subset of patients is likely to benefit from surgery.
Temporally coherent disparity maps using CRFs with fast 4D filtering
Authors: Arjomand Bigdeli Siavash , Budweiser Gregor , Zwicker Matthias
Published: December 2016

State-of-the-art methods for disparity estimation achieve good results for single stereo frames, but temporal coherence in stereo videos is often neglected. In this paper, we present a method to compute temporally coherent disparity maps. We define an energy over whole stereo sequences and optimize their conditional random field (CRF) distributions using the mean-field approximation. In addition, we introduce novel terms for smoothness and consistency between the left and right views. We perform CRF optimization by fast, iterative spatio-temporal filtering with linear complexity in the total number of pixels. We propose two CRF optimization techniques, using parallel and sequential updates, and compare them in detail. While parallel updates are not guaranteed to converge, we show that, in practice with appropriate initialization, they provide the same quality as sequential updates and they also lead to faster implementations. Finally, we demonstrate that the results of our approach rank among the state of the art while having significantly less flickering artifacts in stereo sequences.
