The political vitality and vital politics of Césaire’s Discourse on Colonialism: A reading in light of contemporary racism
Authors: Viveros-Vigoya Mara
Published: August 2019

This article offers a contemporary reading from Latin America of Discourse on Colonialism, one of Martinican writer and political leader Aimé Césaire’s most important works, which is not well known in the Latin American context, despite the great relevance that his politics have in that region. It is one of the strongest interpellations of colonialism and racism as inherent vectors of capitalism and Western modernity and even could be considered as a precursor to critiques of international development thinking and practices. The article includes a short biography of Césaire, and goes on to address how Discourse offers a non-Eurocentric reading of European history, arguing that Nazism is not an outgrowth of or an exception in European history but the ultimate effect of a civilization that justifies colonization. It then describes Césaire’s post-war aspirations for decolonization as a possible third way forward for Europe, breaking with the binarism of capitalism/communism, and outlines questions involving the tensions in the demands for equality and recognition of differences, which stemmed from his involvement in the departmentalization of Martinique in 1946, and the problems that French universalism caused for this process. Rereading Discourse today, there is a distinct blind spot in its androcentrism, and in Césaire’s ignoring of Black women thinkers who were his contemporaries. However, the text still offers original and creative proposals that subaltern groups in Latin America (racialized groups, women, LGBTQ+) can use to observe elements of reality that colonizers and dominant groups are reluctant to acknowledge.
Heterogeneity of public participation in urban redevelopment in Chinese cities: Beijing versus Guangzhou
Authors: Zhang Lin , Lin Yanliu , Hooimeijer Pieter , Geertman Stan
Published: August 2019

Chinese cities, especially large cities, are in urgent need of urban redevelopment but social conflicts in redevelopment processes have threatened social stability. Public participation has been stipulated in national policies to alleviate these conflicts and the responsibility to implement these policies has been delegated to local governments. Therefore, the features of public participation may differ between Chinese cities. Yet, a systematic investigation of this possible heterogeneity is lacking. This article adapts 11 features of governance to build a framework to compare public participation in urban redevelopment in Beijing and Guangzhou. Findings show that the two cities are similar in five features (policy instruments, policy integration, initiators, position of stakeholders, policy level at which citizens operate) but differ in six (policy goals, policy–science interface, power base of citizens, model of representation, rules of interaction and mechanisms of social interaction), making citizens in urban redevelopment in Guangzhou more powerful than their counterparts in Beijing. The observed shift towards urban micro-redevelopment might further strengthen the power of citizens in urban redevelopment in Beijing, but might weaken their power base in Guangzhou. The findings highlight the importance of local context and policy dynamics in the study of public participation in urban redevelopment in China.
Brunner’s gland hamartoma presenting as gastric outlet obstruction: unusual presentation and review of literature
Authors: Gupta Amit , Rajput Depak , Kumar Utkarsh , Gupta Sweety , Singh Ashok , Sanyal Sumit
Published: August 2019

Brunner’s gland hamartoma (or Brunneroma) is an uncommon tumour with an incidence of <0.01%, accounting for approximately 5–10% of benign duodenal tumours. Usually asymptomatic, it may manifest occasionally with duodenal obstruction or upper gastrointestinal haemorrhage and rarely with biliary fistulation, cholestatic jaundice and intussusception. It may be associated with uraemia and chronic pancreatitis. The diagnosis is usually confirmed by imaging studies and upper gastrointestinal endoscopy. Surgical excision or endoscopic resection is preferred for symptomatic large hamartomas. Here we report a case of 45-year-old man presenting with features of pancreatitis and gastric outlet obstruction due to a large Brunner’s gland hamartoma, on his endoscopic, radiologic, surgical and pathologic findings.
Self-plasticization of neoprene rubber via click chemistry from environmentally sustainable cardanol
Authors: Zhang Wenzheng , Jiang Ning , Zhang Tingting
Published: August 2019

The sustainable biomass cardanol grafting onto neoprene (CR) rubber was carried out successfully at room temperature by covalently binding to CR via click chemistry to realize the internal plasticization of CR rubber. The structure of the synthesized product was characterized by Fourier transform infrared spectroscopy and proton nuclear magnetic resonance, and differential scanning calorimetry and thermogravimetric analysis demonstrate a lowering of the glass transition temperature of the CR-propargyl ether cardanol as compared to CR. This confirms the plasticization effect of the cardanol when grafted onto CR. The cardanol as an internal plasticizer also has a good thermal stability and almost near-zero migration.
The Relation Between Early Adolescent Physical Activity and Internalizing Problems: Variations in Exercise Motivations as a Critical Moderator
Authors: Taylor Stephen G. , Zarrett Nicole , Roberts Alex M.
Published: August 2019

Inconsistencies exist regarding the relation between physical activity (PA) and internalizing symptomology in early adolescence, and there is need for investigation of potential moderators that may account for these discrepancies. The current study utilized a Self-Determination Theory Framework to investigate the main effects of five key motivations to exercise and their moderating effects between PA and internalizing problems in an underserved sample of adolescents ( n = 167; mean age = 12.19 years; 73% African American). Analyses showed that intrinsic motivations were negatively related to internalizing problems and extrinsic motivations were positively related. PA was only protective against internalizing problems when intrinsic motivations were high and had iatrogenic effects when these were low. Exploratory analyses further delineated the unique effects of motivational orientations. Clinical implications and future research directions are discussed.
Administering Public Participation
Authors: Eckerd Adam , Heidelberg Roy L.
Published: August 2019

Participation and administration have long had an uneasy coexistence. On one hand, public participation in decisions that affect citizens is consistent with citizenship and democracy; on the other hand, much of what government does is complex and requires some level of technical understanding to make decisions. In this article, we report on public administrators’ perceptions of public participation and the ways that they understand the participation process. We find that public participation is managed by public administrators; they determine the extent of participation, shape the ways that the participation takes place, and decide whether or not participation is valuable for their work. In some cases, the process is rather democratic, whereas in others, it is not. We find that it is up to administrators to shape the spaces for participation and select the participants in a manner consistent with their understanding of the task to be accomplished. We explore this process in the context of Environmental Impact Analysis under the National Environmental Policy Act.
Exploring implicit spaces for constrained sampling-based planning
Authors: Kingston Zachary , Moll Mark , Kavraki Lydia E
Published: August 2019

We present a review and reformulation of manifold constrained sampling-based motion planning within a unifying framework, IMACS (implicit manifold configuration space). IMACS enables a broad class of motion planners to plan in the presence of manifold constraints, decoupling the choice of motion planning algorithm and method for constraint adherence into orthogonal choices. We show that implicit configuration spaces defined by constraints can be presented to sampling-based planners by addressing two key fundamental primitives, sampling and local planning, and that IMACS preserves theoretical properties of probabilistic completeness and asymptotic optimality through these primitives. Within IMACS, we implement projection- and continuation-based methods for constraint adherence, and demonstrate the framework on a range of planners with both methods in simulated and realistic scenarios. Our results show that the choice of method for constraint adherence depends on many factors and that novel combinations of planners and methods of constraint adherence can be more effective than previous approaches. Our implementation of IMACS is open source within the Open Motion Planning Library and is easily extended for novel planners and constraint spaces.
Quantitative susceptibility mapping in spinocerebellar ataxia type 3/Machado–Joseph disease (SCA3/MJD)
Authors: Xie Fangfang , Weihua Liao , Lirong Ouyang , Wang Xiaoyi , Xing Wu
Published: August 2019

Background

The deep nuclei, brainstem, and anterior central gyrus are important sites of spinocerebellar ataxia type3/Machado–Joseph Disease (SCA3/MJD) involvement. These locations were the common iron deposition areas. We hypothesized that iron deposition changes occur in SCA3/MJD patients and are associated with disease progression.

Purpose

Quantitative susceptibility mapping was used to quantitatively analyze changes in iron levels in SCA3/MJD patients.

Material and Methods

Eighteen symptomatic SCA3/MJD patients and 18 age-matched normal controls (group 1; NC1), and 12 asymptomatic mutation carriers (pre-SCA3/MJD) and 16 age-matched normal controls (group 2; NC2) were examined by enhanced gradient echo T2*-weighted angiography. Data were processed to obtain the quantitative susceptibility mapping values. Independent sample t-tests were conducted to compare the differences in the quantitative susceptibility mapping values.

Results

In the red nuclei and substantia nigra, the quantitative susceptibility mapping values of the symptomatic SCA3/MJD group were significantly higher than those of NC1 ( P < 0.05). The quantitative susceptibility mapping values of the symptomatic SCA3/MJD group were higher than those of NC1 in the globus pallidus, but it was not statistically significant ( P = 0.056). No significant difference in quantitative susceptibility mapping values was found between the pre-SCA3/MJD and NC2. No significant correlation was found between the International Cooperative Ataxia Rating Scale and the Scale for the Assessment and Rating of Ataxia and the quantitative susceptibility mapping values.

Conclusion

The results clearly demonstrated the quantitative susceptibility mapping value increase in the globus pallidus, red nuclei, and substantia nigra of the symptomatic SCA3/MJD group, indicating iron overload in these nuclei, suggesting that iron deposition is associated with disease onset.

Published: August 2019

Background:

We evaluated the prognostic role of gross tumor volumes (GTVs) of primary tumor and positive lymph nodes on overall survival (OS) and progression-free survival (PFS) in locally advanced unresectable sinonasal cancer (SNC) treated with definitive intensity-modulated radiotherapy (IMRT) with or without chemotherapy.

Methods:

Primary tumor GTV (GTV-T), pathologic neck nodes GTV (GTV-N), and positive retropharyngeal nodes GTV (GTV-RPN) of 34 patients with epithelial nonglandular SNC receiving IMRT with or without chemotherapy were retrospectively measured. The GTV variables were analyzed in relation with OS and PFS. Survival curves were estimated using the Kaplan-Meier method and compared with the log-rank test. We also estimated the crude cumulative incidence of locoregional relapses only. The optimal volume cutoff value was determined using an outcome-oriented method among the observed values.

Results:

GTV-T was significantly associated with decreased OS ( P=0.003) and PFS ( P=0.003). Moreover, patients with disease total volumes (GTV) smaller than 149.44 cm³ had better OS and PFS than patients with higher volumes ( P<0.0001 for both). Neck nodal metastasis impacted on OS and PFS ( P=0.030 and P=0.033, respectively), but GTV-N did not ( P=0.961; P=0.958). Retropharyngeal nodes metastasis was not associated with prognosis (OS: P=0.400; PFS: P=0.104). When GTV-RPN was added to GTV-N (GTV-TN), a relation with PFS ( P=0.041) and a trend toward significance for OS ( P=0.075) were found.

Conclusions:

Our results show that tumor volume is a powerful predictor of outcome in SNC. This could be useful to identify patients with worse prognosis deserving different treatment strategies.

Published: August 2019

Background:

Most cases of breast lesions of uncertain malignant potential (B3) undergo surgical intervention. We aimed to analyze the outcome of B3 lesion subtypes in a large series of screen-detected cases.

Methods:

We screened 2,986 core needle biopsies to classify B3 lesions. Positive predictive values (PPVs) for malignancy were calculated for a comprehensive risk characterization according to clinicopathologic and morphologic variables.

Results:

B3 lesions comprised 35% atypical ductal hyperplasia (PPV = 20%), 16.7% flat epithelial atypia (PPV = 12%), 22.7% lobular neoplasia (PPV = 16.2%), 9% papillary lesion (PPV = 18.5%), 8.6% phyllodes tumor (PPV = 3.8%), and 8% radial scars (PPV = 4.1%) based on histopathologic diagnosis. Upgrade rates were 15.9% for calcifications, 13.7% for mass lesions, and 16.7% for architectural deformities, with 8.3% of malignant lesions classified as ductal carcinoma in situ and 6.7% as invasive cancers (PPV = 15%).

Conclusion:

B3 lesions entail a heterogeneous risk of malignancy, and careful radiologic–pathologic correlation is required for optimal treatment.
A randomized trial of telemedicine for migraine management
Authors: Friedman Deborah I , Rajan Balaraman , Seidmann Abraham
Published: August 2019

Objective

To determine whether synchronous video-based telemedicine visits with specialists are feasible and to evaluate clinical effectiveness, patient perceptions, and other benefits of telemedicine visits for follow-up migraine care in a tertiary headache center.

Design

A one-year, randomized clinical trial.

Results

Fifty patients were screened and 45 entered the study (43 women, two men). Out of 96 scheduled visits, 89 were successfully conducted using telemedicine. Eighteen patients (out of 22) in the telemedicine cohort and 12 patients (out of 23) in the in-office cohort completed the study. In this small study, clinical outcomes, namely improvement in MIDAS, number of headache days, and average severity at 12 months for participants in the telemedicine group, were not different from those in the in-office group. Convenience was rated higher and visit times were shorter in the telemedicine group.

Conclusions

In this cohort of patients with severe migraine-related disability, telemedicine was a feasible mode of treatment and an effective alternative to in-office visits for follow-up migraine care. Physician productivity could be higher with telemedicine, and patients may get better access because of its convenience.

Trial Registration

This study is listed on ClinicalTrials.gov (NCT01706003).
The Organizational Trap-Gap Framework: A conceptual view of library dysfunction
Authors: Acadia Spencer
Published: August 2019

This article offers a conceptual framework of library dysfunction by defining it in terms of ‘trap-gaps’ that happen when libraries become stuck relying on their outdated, legacy habits that, in turn, lead to discontinuities in new organizational knowledge, competency, and strategy. According to the Organizational Trap-Gap Framework, library leaders may address trap-gaps by blending theories and methods from knowledge management, organizational learning, organizational behavior, and organizational development; supporting a new culture of learning that relies on the socially interactive and performative elements of play, questioning, and imagination; and applying new, reformed processes of knowing, competence, and strategizing. The article concludes with a hypothetical consideration of the trap-gap framework using lack of organizational communication as an example along with further reflection on pertinent issues related to library leaders’ utility of the framework such as top-down dynamics, ethics, and cultural environment.
Knowledge management and innovation: Two explicit intentions pursued by Spanish university libraries
Authors: Pacios Ana R.
Published: August 2019

This article analyses the content of three types of institutional statements (mission, vision and values) published on Spanish university libraries’ websites. The aim is to determine whether they express explicit support for knowledge management and innovation in the university. The analysis revealed that 75% of the population (n = 76) published at least one such statement. The most widely published of the three types was the mission statement, 37 of which contained the terms ‘knowledge’ or ‘innovation’, particularly the former, present in 33. The vision statements of 17 libraries alluded to both, in practically the same proportion. ‘Innovation’ appeared in 20 of 28 libraries with statements of values, denoting the high esteem in which that conceit is held by university librarians. These statements stand as proof that libraries regard innovation and some stage of knowledge management as primary aims, with the furtherance of knowledge creation/generation the one most frequently cited.
Posteromedial Ligament Repair of the Knee With Suture Tape Augmentation: A Biomechanical Study
Authors: Mehl Julian T. , Kia Cameron , Murphy Matthew , Obopilwe Elifho , Cote Mark , Imhoff Florian B. , Imhoff Andreas B. , Arciero Robert A. , Beitzel Knut , Otto Alexander
Published: August 2019

Background:

In cases of acute combined posteromedial and anterior cruciate ligament (ACL) injuries, primary repair of the superficial medial collateral ligament (sMCL) and posterior oblique ligament (POL) with suture tape augmentation may be a reasonable alternative to standard tendon reconstruction techniques.

Purpose/Hypothesis:

The purpose was to examine the rotational and valgus laxity with ACL strain following sMCL and POL repair with suture tape augmentation at various degrees of knee flexion. It was hypothesized that this technique would restore knee laxity and kinematics comparable with those of the intact state.

Study Design:

Controlled laboratory study.

Methods:

Ten cadaveric knee specimens (mean ± SD, 57.9 ± 5.9 years) were obtained. Specimens were tested with the tibia fixed and the femur mobile on an X-Y table. Each specimen was tested in 4 conditions according to the state of the sMCL and POL: native, deficient, repaired with suture tape augmentation, and reconstructed with tendon allografts. Valgus laxity was tested with 40-N force applied in the lateral direction of the femur, and rotational motion was tested with 5-N torque applied to the tibia. ACL strain during valgus stress was also measured. Each condition was tested in 0°, 15°, 30°, 45°, and 60° of knee flexion.

Results:

Dissection of the sMCL and POL led to significantly increased valgus laxity in all flexion angles, with a significant increase in ACL strain at 30° ( P < .001) and 45° ( P < .001). Ligament repair with suture tape augmentation demonstrated similar valgus and rotational laxity as compared with intact specimens, with the exception of increased internal rotation at 30° ( P = .005). Ligament reconstruction resulted in significantly increased valgus opening at 45° ( P = .048) and significantly increased internal rotation at 30° ( P < .001) as compared with the native state. Direct comparison between surgical techniques showed no significant differences.

Conclusion:

At time zero, ligament repair of the posteromedial knee with suture tape augmentation restored close-to-native valgus and rotatory laxity, as well as native ACL strain for cases of complete sMCL and POL avulsion.

Clinical Relevance:

Ligament repair of the sMCL and POL with suture tape augmentation may be a reasonable alternative to tendon reconstruction techniques in cases of acute combined posteromedial and ACL injuries with valgus and rotatory instability.
Patient-Centered Care and Autonomy: Shared Decision-Making in Practice and a Suggestion for Practical Application in the Critically Ill
Authors: Mapes Marianna V. , DePergola Peter A. , McGee William T.
Published: August 2019

Decision-making for the hospitalized dying and critically ill is often characterized by an understanding of autonomy that leads to clinical care and outcomes that are antithetical to patients’ preferences around suffering and quality of life. A better understanding of autonomy will facilitate the ultimate goal of a patient-centered approach and ensure compassionate, high-quality care that respects our patients’ values. We reviewed the medical literature and our experiences through the ethics service, palliative care service, and critical care service of a large community teaching hospital. The cumulative experience of a senior intensivist was filtered through the lens of a medical ethicist and the palliative care team. The practical application of patient-centered care was discerned from these interactions. We determined that a clearer understanding of patient-centeredness would improve the experience and outcomes of care for our patients as well as our adherence to ethical practice. The practical applications of autonomy and patient-centered care were evaluated by the authors through clinical interactions on the wards to ascertain problems in understanding their meaning. Clarification of autonomy and patient-centeredness is provided using specific examples to enhance understanding and application of these principles in patient-centered care.
Water-Related Comfort Properties of Silver-Modified Polyamide Fabrics Treated With Wicking and Antibacterial Finishes
Authors: Duru Sena Cimilli
Published: August 2019

The performance of the active sportswear is mostly related to wetting, wicking, and permeability properties of the fabrics. Antibacterial efficacy of the garments has an important place on the wearer performance. The purpose of this study is to investigate the effects of wicking and antibacterial finishing treatments on water-related comfort properties of seamless garments made from silver-modified polyamide and conventional polyamide fibers. The results showed that silver-modified polyamide fiber performed better at longitudinal wicking height and transfer wicking ratios. Application of antibacterial and wicking finishing treatments reduced the drying rate and water vapor permeability whereas transfer wicking and wicking height values increased. By Lycra incorporation, height of water wicked was much higher while transfer wicking, drying rate, and water vapor permeability were affected negatively. Finally, SWT fabric was found the best, while PWN performed the worst according to the hybrid AHP-TOPSIS method.
Job Loss and Attempts to Return to Work: Complicating Inequalities across Gender and Class
Authors: Damaske Sarah
Published: August 2019

Drawing on data from 100 qualitative interviews with the recently unemployed, this study examines how participants made decisions about attempting to return to work and identifies how class and gender shape these decisions. Middle-class men were most likely to take time to attempt to return to work, middle-class women were most likely to begin a deliberate job search, working-class men were most likely to report an urgent search, and working-class women were most likely to have diverted searches. Financial resources, gendered labor force attachments, and family responsibilities shaped decision making. Ultimately, those in the middle-class appear doubly advantaged—both in their financial capabilities and in their ability to respond to the crisis with greater gender flexibility.
Efavirenz-Induced Vanishing Bile Duct Syndrome: A Case Report
Authors: Nwaesei Angela Shogbon , Moye-Dickerson Pamela M. , Dretler Robin Henry
Published: August 2019

Background:

Efavirenz (Sustiva®) is used for the treatment of human immunodeficiency virus (HIV) type 1 infection. Hepatoxicity is a known potential adverse drug event with efavirenz; however, to our knowledge, vanishing bile duct syndrome (VBDS), a type of liver injury, has not been reported with this therapy.

Case Presentation:

We report the case of a 48-year-old male with HIV and VBDS secondary to antiretroviral therapy. The patient was started on efavirenz, emtricitabine, and tenofovir disoproxil fumarate (Atripla®). Four weeks later, the patient presented with complaints of poor appetite, nausea with emesis, dark urine, and malaise. Labs obtained supported the diagnosis of acute hepatitis, and a liver biopsy confirmed a diagnosis of VBDS. The Naranjo adverse drug reaction probability scale showed that it was probable (score of 7) that the VBDS was related to drug therapy. Efavirenz was assessed to be the most likely cause of VBDS, end-stage liver disease, and the eventual need for liver transplantation.

Conclusion:

To our knowledge, this is the first reported case of probable efavirenz-induced VBDS in a patient living with HIV. Recognition and awareness of this adverse drug reaction by clinicians for quick diagnosis, discontinuation of therapy, and management are important in patients receiving this regimen.
Experimental and numerical investigation of an axisymmetric divergent dual throat nozzle
Authors: Wang Yang-Sheng , Xu Jing-Lei , Huang Shuai , Lin Yong-Chen , Jiang Jing-Jing
Published: August 2019

The dual throat nozzle achieves higher thrust vectoring efficiencies and lesser thrust loss than other fluidic thrust-vectoring nozzles. Separation always occurs at the bottom of the cavity with complex three-dimensional characteristics for the dual throat nozzle. In this paper, by comparing the flow structure, nozzle surface static pressure distributions and skin friction lines, which are obtained by numerical simulations and wind tunnel experiments, an axisymmetric divergent dual throat nozzle is investigated in detail. The main results show the following findings. (1) The experimental schlieren photographs confirm again that the divergent nozzle configuration has the starting problem from an intuitive perspective. Meanwhile, the flow structure and nozzle surface static pressure distributions obtained by numerical simulations are consistent with the experimental results, except for the low nozzle pressure ratios. (2) The circumferential pressure difference is negligible upstream of the separation line but obvious downstream of the separation line. The skin friction lines and nozzle surface static pressure distributions of different circumferential angles obtained by experiments both prove that the actual flow in the axisymmetric divergent dual throat nozzle indeed possesses three-dimensional characteristics. Therefore, it is necessary to utilize the full three-dimensional computational domain to study the complex three-dimensional characteristics of the flow for the axisymmetric divergent dual throat nozzle thoroughly.
Explaining paradigm shifts in Danish anti-discrimination law
Authors: Miller Jeffrey
Published: August 2019

The past three decades have witnessed dramatic transformations in Danish anti-discrimination law. Multiple methodologies—from semi-structured interviews and contemporary newspaper articles to empirical analyses of new datasets—are employed to elucidate how and why these shifts occurred. The analysis focuses on the agency of a small group of well-funded and sophisticated legal actors, who first harnessed the power of the preliminary reference procedure to advance gender discrimination claims in the 1980s and 1990s. This strategy was repeated—successfully—when Denmark adopted disability rights legislation for the first time in the 2000s. The present article builds—and offers a fresh perspective—on existing literature that investigates where, why and how Member State courts engage with EU law and the preliminary reference procedure.
Short-Term Psychological Interventions on Economically Disadvantaged Families: A Systematic Review and Meta-Analysis
Authors: Lo Herman Hay-Ming , Zhang Jiwen , Choi Chun-Wah
Published: August 2019

Purpose:

To examine the effects of short-term psychological interventions on reducing family stress of economically disadvantaged families.

Method:

Systematic review and meta-analytic procedures were used to synthesize the results of randomized controlled studies published between 1980 and 2018.

Results:

The search yielded 8 studies that included results for 1,538 families in total. The risk of bias varied across studies. The meta-analysis results suggest a small positive effect ( g = .38, p < .001) on child behavioral problems. Heterogeneity was relatively high and significant. We also found small to moderate effects on parenting stress, parental depression, and parenting quality ( g ranging from .30 to .51).

Discussion:

The findings of this review suggest that short-term psychological interventions may reduce the family stress of economically disadvantaged families, with effect sizes that are comparable to those of interventions delivered to ordinary families. Implications for further research and practice are discussed.
Confronting Medicine’s Dichotomies: Older Adults’ Use of Interpretative Repertoires in Negotiating the Paradoxes of Polypharmacy and Deprescribing
Authors: Ross Alison , Gillett James
Published: August 2019

To address the risks associated with polypharmacy, health care providers are investigating the feasibility of deprescribing programs as part of routine medical care to reduce medication burden to older adults. As older adults are enrolled in these programs, they are confronted with two dominant and legitimate accounts of medications, labeled the medication paradox: medications keep you healthy but they might be making you sick. We investigated how the medication paradox operates in the lives of older adults. In-depth qualitative interviews were conducted and analyzed with older adults aged 70+ to identify the various paradoxes that seniors live through regarding their medications and the narratives that they engage to negotiate these contradictions. Older adults were found to have established interpretative repertoires to make sense of the incongruent narratives of the medication paradox. In this article, we demonstrate older adults’ efforts to carve out their unique place in the dichotomized institution of medicine.
Body Mass Index and Association With Caries in School-Aged Children With Orofacial Cleft: A Case-Control Study
Authors: Sundell Anna Lena , Nilsson Anna-Karin , Marcusson Agneta , Törnhage Carl-Johan
Published: August 2019

Objective:

Data on the association between body mass index (BMI) and dental caries in children with orofacial clefts are sparse. Therefore, studies on the impact of BMI on caries frequency in children with cleft lip and/or palate (CL/P) are of importance. The aim of the current study was to investigate the association between BMI and frequency of dental caries in children with and without CL/P. Height, weight, and BMI in children with CL/P were also compared to controls.

Design:

This study used a cross-sectional case-control design.

Participants:

One hundred and thirty-nine 5- and 10-year-old children with CL/P and 299 age-matched controls.

Main Outcome Measures:

Caries was recorded according to the International Caries Detection and Assessment System. Height and weight were recorded, and BMI was calculated as weight/height2.

Results:

There was no correlation between BMI and caries frequency. Weight, height, and BMI were significantly lower in all children with CL/P compared to controls. After adjustment for international adoption, only BMI was significantly lower in CL/P children compared to controls. Non-adopted children with CL/P were significantly heavier and longer than adopted children with CL/P.

Conclusions:

Five- and 10-year-old children with corrected CL/P seemed to have a lower BMI than controls, but there was no association between BMI and caries frequency. Internationally adopted children with CL/P were lighter and shorter than non-adopted CL/P children and controls.
Inverse Relationship Between Radiographic Lateral Ankle Instability and Osteochondral Lesions of the Talus in Patients With Ankle Inversion Injuries
Authors: Park Byeong Seop , Chung Chin Youb , Park Moon Seok , Sung Ki Hyuk , Choi Young , Park Chulhee , Koo Seungbum , Lee Kyoung Min
Published: August 2019

Background:

Insufficient or excessive bony constraint surrounding the talus might contribute to the occurrence of ligamentous injury or bone contusion, respectively, at the time of ankle inversion injuries. This study aimed to investigate the relationship between radiographic lateral ankle instability and osteochondral lesions of the talus (OLT) following ankle inversion injuries.

Methods:

A total of 195 patients (113 men and 83 women; mean age, 38.7 years) with a history of ankle inversion injuries were included in this study. All patients underwent ankle magnetic resonance imaging (MRI) and stress radiography. The tibiotalar tilt angle on varus stress radiograph, anterior translation of the talus on anterior-drawer lateral radiographs, bimalleolar tilt angle, and fibular position were radiographically determined. The radiographic lateral ankle instability was defined as tibiotalar tilt angle ≥10 degrees, and the presence of OLT was confirmed on MR images. The relationship between the radiographic lateral ankle instability and the presence of OLT was statistically analyzed.

Results:

The presence of radiographic lateral ankle instability (tibiotalar tilt angle ≥10 degrees) showed an inverse relationship with that of OLT in the chi-squared test ( P = .003). An increased tibiotalar tilt angle was associated with lower incidence of OLT ( P = .011) in the multiple regression analysis, and the presence of OLT was associated with a decreased tibiotalar tilt angle ( P = .016) in the binary logistic regression analysis.

Conclusions:

This study showed an inverse relationship between lateral ankle instability and the development of OLT following ankle inversion injury. The role of bony constraint in the development of sports injuries in the ankle should be considered with these injuries.

A life test of ultrasonic motors under different torque loads and the analysis of the characteristics of wearing surfaces
Authors: Zhang Liwei , Zheng Huiming , Huang Shouqing , Zhang Wu , Li Fangyong , Liu Dazhi
Published: August 2019

Without a coil and a gearbox, an ultrasonic motor has an important application in space engineering and so forth with advantages of light weight, small volume, less electromagnetic radiation, fast dynamic response, and high energy density. However, the obvious friction and wear between the stator and the friction material (as a part of the shaft assembly) restrict the reliability and life time of the ultrasonic motor. In this paper, a life test of ultrasonic motors is designed and carried out for 3041.7 h, and the eight motors are divided into four groups with torque loads of 0.03 Nm, 0.09 Nm, 0.16 Nm, and 0.21 Nm in the test. The evolution characteristics of the displacement frequency response and the wear on the stator contact surface under different torque loads during the wear process are analyzed. Some start-up problems occur during the early time in the life test are found and explained based on a meshing effect between the stator and the friction material, and some targeted suggestions are proposed to overcome the problems. The study can help to understand the wear failure mechanism and characteristics of ultrasonic motors.
Florian Znaniecki’s cultural psychology project
Authors: Chojniak Arleta A
Published: August 2019

The aim of this paper is to present the project of cultural psychology formulated by Florian Znaniecki, a Polish philosopher, sociologist and pioneer of social psychology. His view of cultural psychology was connected with the concept of social psychology and was founded on the assumption of culturalism and the theory of cultural actions. Znaniecki’s cultural psychology represents the antipositivistic turning in the social sciences and the humanities and is opposite to the naturalistically oriented psychology. His proposition is also an attempt to go beyond the individualistic or antiindividualistic perspective in the cultural psychology.

There is an increasing number of shared decision-making (SDM) interventions in paediatrics. However, there is little consensus as to the best instruments to assess the feasibility and impact of these interventions. This narrative review aims to answer: (1) what feasibility, knowledge and decision-making instruments have been used to assess paediatric SDM interventions and (2) what are the psychometric properties of used decision-making instruments, guided by the ‘consensus-based standards for the selection of health measurement instrument’ criteria. We conducted a review of the peer-reviewed literature. We identified 23 studies that evaluated a paediatric intervention to facilitate SDM for a specific health decision. Eighteen studies assessed intervention feasibility, with a wide variability in assessment between studies. Twelve studies assessed objective knowledge, and four studies assessed subjective knowledge with all but one study aggregating correct responses. We identified nine decision-making instruments that had been assessed psychometrically, although few had been thoroughly evaluated. The Decisional Conflict Scale was the most commonly-used instrument and the only instrument evaluated in paediatrics. Our study revealed a lack of consistency in the instruments used to evaluate decision-making interventions in paediatrics, making it difficult to compare interventions. We provide several recommendations for researchers to improve the assessment of SDM interventions in paediatrics.
Measuring Digital Capital: An empirical investigation
Authors: Ragnedda Massimo , Ruiu Maria Laura , Addeo Felice
Published: August 2019

This article develops a Digital Capital Index by adopting the definition provided by Ragnedda, who defines Digital Capital as the accumulation of digital competencies and digital technologies, and the model for measuring it developed by Ragnedda and Ruiu. It aims to develop a measure that can be replicated for comparison in different contexts. This article contributes both theoretically and empirically to the literature by (a) consolidating the concept of Digital Capital as a specific capital and (b) empirically measuring it. A Digital Capital Index is developed through an exploratory factor analysis (EFA) and validated with a representative sample survey of 868 UK citizens. The validation procedure shows that the Digital Capital Index is associated with socioeconomic and sociodemographic patterns, such as age, income, educational level and place of residence, while it appears not to be related to gender.
Becoming through doing: How experimental spaces enable organizational identity work
Authors: Bojovic Neva , Sabatier Valérie , Coblence Emmanuel
Published: August 2019

This qualitative study of a magazine publishing incumbent shows how organizational identity work can be triggered when organizational members engage in business model experimentation within the bounded social setting of experimental space. The study adds to the understanding of the strategy-identity nexus by expanding on the view of business models as cognitive tools to business models as tools for becoming and by understanding the role of experimental spaces as holding environments for organizational identity work. We show how an experimental space engages organizational members in experimental practices (e.g. cognitive, material, and experiential). As firms experiment with “what they do,” organizational members progressively confront the existing organizational identity in the following ways: they engage in practices of organizational identity work by coping with the loss of the old identity, they play with possible organizational identities, and they allow new organizational identity aspirations to emerge. In these ways, experimental spaces act as an organizational identity work space that eventually enables organizational identity change. We identify two mechanisms (i.e. grounding and releasing) by which an organizational identity work space emerges and leads to the establishment of a renewed organizational identity.
The lay health worker–patient relationship in promoting pulmonary rehabilitation (PR) in COPD: What makes it work?

Lay health workers (LHWs) can improve access to services and adherence to treatment, as well as promoting self-care and prevention. Their effect in promoting uptake and adherence in pulmonary rehabilitation (PR) for chronic obstructive pulmonary disease (COPD) has not been tested. PR is the most effective treatment for the symptoms and disability of COPD, but this effectiveness is undermined by poor rates of completion. Trained LHWs with COPD, who also have first-hand experience of PR, are well placed to help overcome the documented barriers to its completion. The relationship between LHWs and patients may be one of the keys to their effectiveness but it has been little explored. Semi-structured qualitative interviews were used with the aim of examining the LHW-patient partnership in a feasibility study of trained PR-experienced LHWs used to support COPD patients referred to PR. Twelve volunteers with COPD who completed LHW training supported 66 patients referred for PR. All 12 of these LHWs gave end-of-study interviews, 21 COPD patients supported by LHWs were also interviewed. Patients reported that the LHWs were keen to share their experiences of PR, and that this had a positive impact. The enthusiasm of the LHWs for PR was striking. The common bond between LHWs and patients of having COPD together with the LHWs positive, first-hand experience of PR were dominant and recurring themes in their relationship.
The Prognostic Landscape of Tumor-Infiltrating Immune Cells and Immune Checkpoints in Glioblastoma

Tumor-infiltrating immune cells are part of a complex microenvironment and associated with improved clinical outcomes in a broad range of tumor types. However, a detailed map for the prognostic landscape of tumor-infiltrating immune cells and immune checkpoint modulators in glioblastoma is still lacking. Here, with the web-accessible resource, The Cancer Immunome Archive, 28 types of both adaptive and innate tumor-infiltrating immune cells were characterized in glioblastoma. Tumors lacking central memory CD4 T cells or natural killer cells were associated with better prognosis in glioblastoma, as verified by immunohistochemical analysis. Moreover, Kaplan-Meier analysis for a total of 71 key immune checkpoint molecules revealed that the expression level of inducible T cell costimulators, tumor necrosis factor superfamily member 14, and UL16 binding protein 1 were negatively correlated with the clinical outcome of patients with glioblastoma. In addition, there was a significant difference between nontumor and glioblastoma samples of several immune checkpoint modulators based on the expression level of their corresponding gene. Collectively, the annotation of tumor-infiltrating immune cells and immune checkpoint modulators in glioblastoma provides a valuable resource for identifying their involvement in tumor escape mechanisms and response to therapy.
Resisting War: Guinean Youth and Civil Wars in the Mano River Basin
Authors: Bangura Ibrahim
Published: August 2019

For more than two decades, the Mano River Basin was trapped in a spiral of violent civil wars at the centre of which were the region’s youth. However, in spite of the similarities in contexts, and despite its history and external attacks by insurgency groups based in Liberia and Sierra Leone, Guinea did not degenerate into a civil war. The immediate question then is, what factors might have been responsible at that time for mitigating the potential involvement of the country’s youth in a civil war, and can the lessons learned from Guinea be emulated in conflict-affected countries today? This article provides in-depth perspectives into the Guinean youth and the factors that mitigated their involvement in violent insurrections against the state from 1989 to 2011. It also juxtaposes the findings on Guinea with conclusions on factors responsible for involvement of youth in the civil wars in other countries in the region.
Exploring the Intersection of Violence Against Women and Girls With Post-Conflict Statebuilding and Peacebuilding Processes: A New Analytical Framework
Authors: Swaine Aisling , Spearing Michelle , Murphy Maureen , Contreras-Urbina Manuel
Published: August 2019

Conflict-related violence against women and girls (VAWG) has drawn increasing attention, yet scholars, policymakers, and practitioners focussed on conflict-related VAWG and those focussed on post-conflict statebuilding and peacebuilding have largely worked separately. Less attention has been given to VAWG during post-conflict transitions than during conflict itself. This article makes three major contributions to guide researchers and policymakers in addressing VAWG in post-conflict contexts. First, it identifies critical gaps in understanding the intersection between VAWG and post-conflict statebuilding and peacebuilding processes. Second, it presents an ecological model to explore the drivers of VAWG during and after armed conflict. Third, it proposes a conceptual framework for analysing and addressing the intersections of VAWG with both post-conflict statebuilding and peacebuilding. The article concludes that application of this framework can help policymakers shape statebuilding and peacebuilding processes to more effectively institutionalise approaches to VAWG so that post-conflict transitions advance sustainable, positive peace.
