Why Tourists Choose Airbnb: A Motivation-Based Segmentation Study
Authors: Guttentag Daniel , Smith Stephen , Potwarka Luke , Havitz Mark
Published: April 2017

Airbnb has grown very rapidly over the past several years, with millions of tourists having used the service. The purpose of this study was to investigate tourists’ motivations for using Airbnb and to segment them accordingly. The study involved an online survey completed in 2015 by more than 800 tourists who had stayed in Airbnb accommodation during the previous 12 months. Aggregate results indicated that respondents were most strongly attracted to Airbnb by its practical attributes, and somewhat less so by its experiential attributes. An exploratory factor analysis identified five motivating factors—Interaction, Home Benefits, Novelty, Sharing Economy Ethos, and Local Authenticity. A subsequent cluster analysis divided the respondents into five segments—Money Savers, Home Seekers, Collaborative Consumers, Pragmatic Novelty Seekers, and Interactive Novelty Seekers. Profiling of the segments revealed numerous distinctive characteristics. Various practical and conceptual implications of the findings are discussed.
Modeling, simulation and control of the dynamics of a Heptads’ effect evaporator system used in the Kraft recovery processes
Authors: Verma Om Prakash , Mohammed Toufiq Hazi , Mangal Shubham , Manik Gaurav
Published: April 2017

This research article attempts to investigate the dynamic behavior of the heptads’ effect evaporator (HEE) used to concentrate the weak black liquor during the Kraft recovery process in a paper industry. In order to fully characterize the HEE unit, a complete understanding of its performance for steady state and transient conditions is required. For this purpose, a set of first order nonlinear differential equations have been developed for the backward feed flow configuration (BFFC) for an unsteady state. Further, the developed non-linear model is linearized and linear state space equations obtained. The dynamic response of the system in terms of vapor temperature and liquor concentration changes for different changes in input liquor flow rate has been investigated. The rise, delay and settling times for the temperature deviation from steady state have been found to be significantly less as compared with that for the concentration deviation. The results also indicate that each effect of HEE acts as an individual first order system. The placement of such first order systems in series makes both the liquor concentration and vapor temperatures response more sluggish progressively with each subsequent effect. Finally, a Cascade-PID control strategy has been implemented and shown to exhibit differentiated and improved dynamic performance of the HEE system versus open-loop dynamic response.
Moral cosmopolitanism and the everyday life: how students encounter distant others
Authors: Vandevoordt Robin
Published: April 2017

While moral cosmopolitanism has been at the heart of many theoretical debates for decades if not centuries, empirically driven analyses have only comparably recently fed into a growing body of literature. Most of these recent studies have successfully mapped the discourses, dispositions and affects through which individual actors interpret and experience their encounters with distant others. This article seeks to contribute to this line of empirical research by exploring the everyday situations and spheres in which these discourses and dispositions are embedded. In doing so, this study draws on a qualitative analysis of 19 students’ encounters with distant others, through both a 10-day diary on their media use and in-depth individualised interviews.
Who watches Korean TV dramas in Africa? A preliminary study in Ghana
Authors: Kim Suweon
Published: April 2017

More and more Ghanaians are watching Korean TV dramas. These are not just ordinary Ghanaians because they are from a particular socioeconomic bracket; they have a certain level of education, access to screen devices and Internet, accumulated previous experience of watching other foreign screen products and, most importantly, a peer network with those who can afford these items. Drawing from qualitative work and focus-group interviews, the article argues that Korean TV dramas are spread efficiently by taking advantage of those contributing components within the privileged network, but they remain within the network due to the lack of those necessary components outside the bracket. The recipients find Korean media products attractive because they are fresh, funny, socially decent, different, yet close to them vis-à-vis Hollywood and Nollywood.
Viscosity reduction of extra heavy crude oil by magnetite nanoparticle-based ferrofluids
Authors: Aristizábal-Fontal Juan E , Cortés Farid B , Franco Camilo A
Published: April 2017

The main objective of this work is to synthesize and evaluate magnetite (Fe3O4) nanoparticle-based ferrofluids for reducing the viscosity of an extra heavy crude oil. The carrier fluid of the nanoparticles was synthesized using an engine lubricant recycled from the automotive industry and hexadecyltrimethylammonium bromide as a surfactant. Fe3O4 nanoparticles were synthesized by coprecipitation method. The effect of the concentration of nanoparticles in the viscosity reduction degree was determined for dosages between 0 and 50,000 mg/L. Different dosages of carrier fluid were evaluated between 0 and 10% v/v. The effects of the amount of brine emulsified, temperature, time, and shear rate were assessed. Overall, the results showed that viscosity and shear stress of extra heavy crude oil could be reduced up to 81 and 78% in the presence of ferrofluid, respectively. The rheological behavior of extra heavy crude oil in the presence and absence of ferrofluid was assessed by Cross, Ostwald-de Waele, and Herschel-Bulkley models.
M2 segment dissection of middle cerebral artery diagnosed using high-resolution magnetic resonance imaging
Authors: Song Xiaoyan , Lv Haiyan , Tang Jianjun , Zhang Qing , Wang Qiaoshu
Published: April 2017

Middle cerebral artery (MCA) dissection is a rare cause of ischemic stroke, especially in the M2 or M3 segments. Diagnosis of intracranial artery dissection remains challenging. We herein report a case of M2 segment dissection of the MCA with typical features of an intimal flap and intramural hematoma diagnosed using high-resolution 3T magnetic resonance imaging. This imaging technique might be a more effective noninvasive method by which to diagnose M2 segment dissection of the MCA than either computed tomography angiography or digital subtraction angiography.
The Emerging Health Leaders network experience: Reflections and lessons learned from a grassroots movement
Authors: Gruenwoldt Emily , Hagen Lyster Adrienne
Published: April 2017

The Emerging Health Leaders (EHL) network was established in 2006 to enhance the leadership capacity of early careerists in the health sector in Canada. Ten years later, the development of the next generation of health leaders continues to be a focus for system leaders. Despite the rhetoric, financial investments in leadership development remain stagnant. This article describes the network’s experience in supporting the professional development needs of aspiring leaders across Canada. Successes and challenges regarding the development of the network are discussed, as are the results from a recent benchmarking survey, which identify remaining gaps and priorities for aspiring young leaders. Recommendations are also provided—based on the EHL experience—about how senior leaders can look to support and leverage the contributions of young leaders.

The necessity for boundary corrections in a standard practice for the open-jet wind tunnel testing of automobiles
Authors: Cooper Kevin R , Mercker Edzard , Müller Jürg
Published: April 2017

This paper is intended to provide a summary of the necessary adjustments required for road-representative open-jet wind tunnel measurements on automobiles. The open-jet wind tunnel provides accurate measurements, but they are made in a finite-sized jet that differs from the unconfined open-road conditions. Furthermore, measurements on a given automobile made in different open-jet wind tunnels disagree with each other, and with measurements in closed-wall wind tunnels that were corrected for the influences of their solid boundaries. There appears to be reticence at some company levels to making ‘corrections’ to open-jet measurements. Perhaps non-specialist managers think that the need for a ‘correction’ means an erroneous measurement. It does not! Any high-quality wind tunnel measurement is accurate, but it needs to be ‘calibrated’ to on-road conditions through an appropriate set of procedures. Closed-wall wind tunnels measure higher drag coefficients, in comparison with those in an unconstrained on-road flow. Open-jet wind tunnels frequently measure a lower value. The closed-wall adjustments lower the drag coefficient to the unconstrained value. Open-jet adjustments should also adjust the drag coefficient to the same unconstrained value. This paper explores the range of effects from the finite jet and elucidates the effectiveness of a two-measurement correction procedure. It is shown that not every data point must be measured twice, only a small selected subset. Since approximately 20% of tunnel occupancy is in the fan-on condition, then the additional cost of correct accurate on-road-equivalent data is low.
Fuel remains in archaeological contexts: Experimental and archaeological evidence for recognizing remains in hearths used by Iron Age farmers who lived in peatlands
Authors: Braadbaart F , van Brussel Ton , van Os Bertil , Eijskoot Yurie
Published: April 2017

In the archaeological record, ash and charred organic material are the only indications of the type of fuel used by ancient societies to feed their fires. This potential source of information may help further understanding of past human behaviour in relation to fuel selection, applied type of fire and function of fires lit in hearths. This study examined ash from reference samples and ash and char samples recovered from an Iron Age peatland site in Vlaardingen, the Netherlands. Local availability and abundance made it possible for the occupants of the site to choose from different fuel resources. Peat and cattle dung were readily available, while wood was less abundant. Reference samples from various locations were collected to investigate the properties of ash. Different types of wood, peat and cattle dung were accordingly ashed and analysed. In total, two techniques were used, that is, chemical analyses (x-ray fluorescence (XRF)) for the determination of the elemental composition and microscopic studies on field images of these ashes, mounted on glass slides, to investigate phytoliths quantitatively (Si and Ca types), siliceous aggregates and spherulites. The properties of the archaeological samples were compared with these results. The archaeological char samples were used for identification and analysed using reflective microscopy to study structure and temperature by reflectance (%Ro). It provided the necessary information to determine the type of fuel used by the Iron Age farmers and obtain more information on the function of the present fire structures. The results are strong indications that Iron Age farmers used all available fuels, that is, peat, cattle dung and wood, to feed their fires. The integrated application of phytolith, geochemical and char analyses has a high potential for the identification of the fuel selected by ancient societies.
Cost-effectiveness of the Yashoda Programme
Authors: Saha Somen , Varghese Beena
Published: April 2017

Background:

Under the Norway-India Partnership Initiative (NIPI), a pilot programme was launched in 2008 to improve the quality of institutional maternal and neonatal care through Yashodas or birth companions. Yashodas were placed at higher-level healthcare facilities across select districts of India to support mother and newborn. This article presents the additional cost of the Yashoda programme from a government perspective and models the potential cost-effectiveness of the Yashoda intervention in averting neonatal deaths.

Methods:

We estimated the additional costs of the Yashoda programme (2011–2012) using an activity-based costing approach from a provider perspective. Effectiveness measure was estimated as the difference in the average rate of receipt of counselling (for mothers who delivered at district hospitals) between intervention and comparison districts. The potential impact of the Yashoda programme on neonatal mortality was modelled from secondary data assuming a 30 per cent reduction in neonatal mortality among those who received counselling and practiced safe newborn care practices.

Results:

The additional cost of Yashoda intervention was US$26,350 per year or US$0.83 per live birth. Eighty-four per cent of mothers in the intervention group received essential postpartum newborn care counselling at the facility compared to 62 per cent of mothers in the comparison groups. Through potential change in newborn care practices, the Yashoda intervention was estimated to avert 45 neonatal deaths for a hypothetical cohort of 100,000 mothers who delivered at district hospitals. The incremental cost of the Yashoda intervention was US$1,832 per neonatal death averted or US$29 per life year saved (LYS). Sensitivity analysis showed the incremental cost per LYS of the Yashoda intervention varied between US$14 and US$59.

Conclusion:

This study concludes that the Yashoda intervention, when scaled up at high delivery load facilities, is a very cost-effective intervention to save newborn lives.
Government policy and private sector development in post-conflict states: Growing Cambodia’s rice production and export industries
Authors: Turner Mark , Korm Ribaun , Veara Kim
Published: April 2017

This article deals with the rehabilitation of economies in post-conflict states, paying particular attention to the role played by the state in this process. Using the example of Cambodia and its policies on rice production and export, the article shows the prominent role that may be played by the state in prioritised areas of economic development where there has been market failure. In the Cambodian case, the government targeted rice production and export as these had great potential for promoting the major aims of national development policy – economic growth and poverty alleviation. Using a whole-of-government approach and a combination of direct involvement and the creation of an enabling environment, the government appears to have contributed to vastly increased rice production and export.
Youth survival in the labour market: Employment scarring in three transition economies
Authors: Mojsoska-Blazevski Nikica , Petreski Marjan , Bojadziev Marjan I
Published: April 2017

The aim of this study is to examine whether the prevalent and fairly long unemployment spell of young Macedonians, Serbians and Montenegrins early in their career has negative effects on their subsequent labour-market performance: the so-called employment scarring. We first model unemployment spell as a function of individual and household characteristics and work attitudes and preferences using a discrete-time duration method. Then, we estimate the survival probabilities to examine the potential existence of employment scarring. The results provide some evidence for the potential presence of employment scarring in the three countries. The scars are largest in Serbia for all durations of the unemployment spell followed by Macedonia; they are weakest in Montenegro.

Falls Suffered by Elderly People From the Perspective of Health Care Personnel: A Qualitative Study
Authors: López-Soto Pablo J. , García-Arcos A. , Fabbian F. , Manfredini R. , Rodríguez-Borrego M. A.
Published: April 2017

An exploratory interpretative study was carried out to recognize the factors regarded by health care professionals as potential obstacles to the evaluation, prevention, and documentation of falls in persons above 65 years of age. Focus groups and questionnaires were carried out. Audio recordings were made, and these were subsequently transcribed and analyzed in accordance with the Bardin’s thematic content analysis. Four focus groups of four persons were set up, and 16 questionnaires were returned. Four thematic categories were obtained. The analysis showed a lack of data in records of falls, perhaps for reasons of overwork, lack of motivation, awareness, or consistency in the registration systems in use. Health care professionals document two types of fall, depending on the elderly person’s ability to carry out everyday tasks. There is not a rigorous and systematic approach for recording falls. Perspectives from health care professionals could help in analyzing the causes of falls and suggesting comprehensive preventive measures.
The Arterial Anatomy of the Deltoid Ligament: A Cadaveric Study
Authors: Haynes Jacob A. , Gosselin Michelle , Cusworth Brian , McCormick Jeremy , Johnson Jeffrey , Klein Sandra
Published: April 2017

Background:

There is an increasing interest in the operative treatment of deltoid ligament disruption in the setting of chronic ankle instability. Understanding the vascular anatomy of the deltoid complex is beneficial when considering operative procedures on the medial ankle and may provide insight into factors that lead to chronic deltoid insufficiency and ankle instability.

Methods:

Thirty-two pairs of cadaveric specimens (64 total legs) were amputated below the knee, and the tibialis anterior, tibialis posterior, and peroneal arteries were injected with India ink and Ward’s blue latex. Specimens then underwent chemical debridement to identify the vascular supply to the deltoid ligament. A subset of specimens also underwent intraosseous debridement using the modified Spalteholz technique.

Results:

The vascular supply to the deltoid ligament was clearly visualized in 60 (93.8%) specimens. Fifty-eight specimens (96.7%) had arterial supply with an origin from the medial tarsal artery, 57 specimens (95%) had supply from the tibialis posterior artery, and 23 (38.3%) specimens had supply from the tibialis anterior artery. All specimens had at least 1 location of intraosseous vascular supply, either at the medial malleolus or medial talus.

Conclusion:

There were 3 separate extraosseous sources and 2 intraosseous sources of vascular supply to the deltoid ligament.

Clinical Relevance:

Knowledge of the vascular supply may aid in identifying factors that predispose a subset of patients with medial ankle sprains to failure of conservative treatment, as well as provide useful anatomic information when considering operative treatment for chronic ankle instability.

Authors: Uçar Halit Necmi , Eray Şafak , Vural Ayşe Pınar , Kocael Ömer
Published: April 2017

Objective: In this study, our objective is to assess the perception of family environments by adolescents with ADHD based on perceived expressed emotion (EE) and the self-esteem of the adolescents. Method: Uludag University Medical Faculty Hospital completed this study with 41 adolescents with ADHD and 35 control group participants who were matched based on age and gender. Results: The total scores of perceived EE, described as a lack of emotional support, irritability, and intrusiveness, were significantly higher in ADHD group than in the control group. The group with ADHD also showed significantly lower self-esteem. There was a negative correlation between self-esteem scores and total perceived EE scores in the ADHD group and the control group. Conclusion: This study showed that the adolescents with ADHD perceive less emotional support and higher levels of intrusiveness, with patients also describing their families as more irritating. Other results in this study show that adolescents with less emotional support possess lower self-esteem, as do adolescents with more irritable parents.
A study of the stressors and coping behaviors of parents of Chinese hemophilic children
Authors: Peng Jie , Yang Hongbin , Fu Gan , Zhao Xielan , Li Xiaolin , Chen Fangping
Published: April 2017

To understand the stressors experienced by parents of hemophiliac children in China and the coping behaviors utilized, semi-structured interviews were conducted with parents of 158 Chinese hemophiliac children. We administered the Coping Health Inventory for Parents to determine coping behaviors. Parents’ main stressors were in the domains of children’s illness and physical condition, economic problems, and so on. Parents engaged in various positive coping behaviors to manage these stressors. The helpfulness of these coping behaviors in maintaining a normal family life differed significantly by parents’ education and income ( p < .01). Parents of hemophilic children in China face numerous stressors but engage in a number of coping behaviors to manage these stressors. While treating hemophilic children, Chinese medical workers should guide parents to adopt such positive coping behaviors.
Digitizing localism: Anticipating, assembling and animating a ‘space’ for UK hyperlocal media production
Authors: Rodgers Scott
Published: April 2017

This article presents an unconventional view of media production, not as the direct production of media content or forms, but the cultivation of spaces for media production taking place elsewhere. I draw on a close analysis of Destination Local, a program of UK charity Nesta, which focused on the implications of location-based technologies for the emergent field of ‘hyperlocal’ media. Although the first round of the program – the focus in this paper – funded 10 experimental projects alongside extensive research, my argument is that Destination Local was less a matter of enabling specific place-based hyperlocal media outlets. Rather, it was an attempt to anticipate, assemble and animate a broader UK hyperlocal media ‘space’, composed of both technical ecologies (e.g. data, devices, platforms, standards) and practical fields (e.g. journalism, software development, local government, community activism). This space, I argue, was anchored to a largely implicit political discourse of localism.
Fracture liaison services: do they reduce fracture rates?
Authors: de Bruin Irma J. A. , Wyers Caroline E. , van den Bergh Joop P. W. , Geusens Piet P. M. M.
Published: April 2017

The fracture liaison service (FLS) care is considered the most appropriate organizational approach for secondary fracture prevention. We performed a literature search to evaluate to what extent the introduction of a FLS reduced subsequent fracture rates. We identified five studies that compared subsequent fracture rates. These studies varied in study design, proportion of women, baseline and subsequent fracture type [vertebral fracture (VF), non-VF (NVF) or hip fractures], duration of follow-up, response rates of attending the FLS, as well as variables included in adjusted analyses (age, sex, baseline fracture, time dependency). In two studies comparing hospitals with and without a FLS, the adjusted hazard ratio (HR) for subsequent fractures was significantly lower in the FLS hospitals (HR: 0.84 during the first year, 0.44 during the second year for subsequent NVFs after baseline NVF, and 0.67 during the third year for subsequent VFs + NVFs after baseline VFs + NVFs). When comparing fracture rates before (pre-FLS) and after (post-FLS) introduction of a FLS, the adjusted HR for subsequent NVFs after baseline NVF was significantly lower in the post-FLS group after 2 years in one study (HR = 0.65) and nonsignificant in another study for subsequent hip fractures after baseline hip fracture. One study comparing pre-FLS and post-FLS with a follow-up of less than a year did not demonstrate a significant difference in subsequent fracture risk. In conclusion, only five FLS studies with heterogeneous study designs are available, three of them reported a lower subsequent fracture rate related to FLS care. Larger and long-term studies will be needed to further quantify the effect of FLS care on subsequent fracture risk.
A Midterm Review of Lesser Toe Arthrodesis With an Intramedullary Implant
Authors: Harmer James Lee , Wilkinson Anthony , Maher Anthony John
Published: April 2017

Lesser toe deformities are one of the most common conditions encountered by podiatric surgeons. When conservative treatments fail surgical correction is indicated. Many surgical options have been described to address the complex nature of these deformities but no perfect solution has been reported to date. However, with the continued advancement of internal fixation technology, interphalangeal joint (IPJ) arthrodesis with an intramedullary implant may be a good option. This retrospective study presents patient reported outcomes and complications at 6 months and 3 years following lesser toe proximal interphalangeal joint (PIPJ) arthrodesis with a polyketone intrameduallary implant (Toe Grip, Orthosolutions, UK). Between September 2011 and November 2012, a total of 38 patients attended for second toe PIPJ arthrodesis by means of the Toe Grip device. At 6 months postoperation, 94.7% of patients and at 3 years postoperation, 92.8% of patients felt that their original complaint was better or much better. Health-related quality of life scores continued to improve overtime as measured by the Manchester Oxford Foot Questionnaire. Complications were generally observational and asymptomatic. The most common complications were floating toes (17.8%), mallet deformities (14.2%), metatarsalgia (17.8%), and transverse plane deformity of the toe (10.7%). This study demonstrates excellent patient-eported outcomes with minimal symptomatic complications making the “Toe Grip” implant a safe and effective alternative fixation device for IPJ arthrodesis when dealing with painful digital deformities.

The Bias of Provocation Narratives in International News
Authors: Boudana Sandrine , Segev Elad
Published: April 2017

This paper explores how provocation narratives introduce political bias in international news. It is based on a two-step methodology. First, a network analysis of country co-mentions in American, British, French, and German news corpus shows that core countries (e.g., the United States) and their opponents (e.g., North Korea, Russia, Iran) are the most frequently cited in provocation narratives. Focusing on the case where provocation narratives are the most prominent, the Korean conflict, we then employ a quantitative content analysis to identify the relationships between the countries involved in news stories using provocation narratives, and the role played by the provocation in those news stories. Our findings show that bias is introduced in many instances where journalists, while repeatedly identifying one country, North Korea, as the provocateur, omit key information such as the reasons behind North Korea’s provocations or the identity of the provoked country. This indicates that provocation narratives adopt the core countries’ geopolitical views and portray their enemies as a global threat.
Resistance Training in Youth: Laying the Foundation for Injury Prevention and Physical Literacy
Authors: Zwolski Christin , Quatman-Yates Catherine , Paterno Mark V.
Published: April 2017

Context:

The rising incidence of physical activity– and sports-related injuries has prompted the present-day investigation of resistance training as a potential means of injury prevention and physical literacy development among youth.

Evidence Acquisition:

Relevant studies on the topics of athlete development, physical literacy, resistance training, and injury prevention in children and adolescents were reviewed (PubMed and Sports Discus, 1982-2016). Recommendations from consensus guidelines and position statements applicable to resistance training and injury prevention in youth, in addition to young athlete development, were reviewed. Additionally, hand searches, expert requests, article reference lists, and gray literature were utilized and reviewed for pertinent content.

Study Design:

Clinical review.

Level of Evidence:

Level 4.

Results:

Youth throughout the physical activity spectrum are at risk for physical activity– and sports-related injury. Of highest priority are early specializers, physically inactive youth, and young girls, owing to increased injury rates. Resistance training among these at-risk populations has been shown to reduce injury risk by up to 68% and improve sports performance and health measures, in addition to accelerating the development of physical literacy. Recent recommendations, position statements, and national initiatives advocate for the incorporation of resistance training with qualified instruction among these groups.

Conclusion:

Resistance training in addition to free play and other structured physical activity training can serve as a protective means against injury and a positive catalyst for the development of physical literacy to offset the impact of diminishing physical activity and early sport specialization in today’s youth.
Giving the Underdog a Leg Up
Authors: Bruneau Emile , Lane Daniel , Saleem Muniba
Published: April 2017

In the current work, we experimentally examined the effect of exposure to a narrative of nonviolent resistance on third-party attitudes toward and support for a disempowered group involved in asymmetric conflict. Across three experiments, we found that Americans exposed to a brief video about Palestinian nonviolent resistance consistently registered more favorable attitudes toward Palestinians than people who watched a film trailer either unrelated to the Israeli–Palestinian conflict or a trailer to a Palestinian-made film about sympathetic Palestinians violently opposing Israelis. Americans’ attitudes toward Palestinians and behavior supporting Palestinian collective action persisted weeks after exposure to nonviolent resistance and were mediated by decreased perceptions that Palestinians are inherently violent. Importantly, positive attitudes toward Palestinians did not result in increased negativity toward Israelis. These data show that exposure to nonviolent resistance can have lasting effects on third-party attitudes and behavior toward an underdog/disempowered group, without driving partisanship.
Advancing integrated care and its evaluation by means of a universal typology
Authors: Busetto Loraine , Luijkx Katrien , Vrijhoef Hubertus Johannes Maria
Published: April 2017

Health systems around the globe implement integrated care interventions to address the Triple Aim of simultaneously improving population health, patient experiences and cost-efficiency. However, the underlying definitions and conceptualisations of integrated care often differ considerably, which makes uniform measurement and comparison difficult. Rather than agreeing on one definition of integrated care, we argue that a universal typology of integrated care interventions should be developed to enable the comparison of interventions that are based on different understandings of integrated care. This universal typology should combine rankable and intangible components with unrankable and tangible sub-components, and be conceptually sound and flexible. The content of the typology should be developed by an international consortium of relevant stakeholders.
Is Inequality Designed or Preordained?
Authors: Levin-Waldman Oren M.
Published: April 2017

The conventional explanation of raising income inequality is often referred to as the market forces hypothesis. Global forces have led to structural economic changes in which we now have a two-tiered economy: a highly skilled and highly paid economy at the top of the income distribution and a poorly skilled and poorly paid economy at the bottom of the income distribution. In recent years, however, the conventional theory has been called into question by what can be characterized as the public policy hypothesis that holds that it is because of public policy, both active and passive, that labor market institutions that served to bolster incomes of the poor and middle class deteriorated. As a consequence of this deterioration, income inequality has only risen. Through an examination of data from the Current Population Survey during the 2000s, this article seeks to address to what extent these two hypotheses are related. Although there is no question that the data does support the market forces hypothesis, the data also show that these forces may have been exacerbated by the deterioration of important labor market institutions.
Tacrolimus-Associated Dilated Cardiomyopathy in Adult Patient After Orthotopic Liver Transplant
Authors: McLeod Jennifer , Wu Stephanie , Grazette Luanda , Sarcon Anna
Published: April 2017

This report presents a case of tacrolimus cardiotoxicity in an adult patient who received tacrolimus immunosuppression for orthotopic liver transplant (OLT). Tacrolimus-associated cardiotoxicity has been described in the literature, however this is the first case to document the development of a dilated cardiomyopathy in a patient shortly after initiating tacrolimus therapy post transplant. With the growing use of tacrolimus in transplant medicine, this case report expands the literature of tacrolimus cardiotoxicity and can aid clinicians in the evaluation and management of patients exposed to this form of immunosuppression.
Early Osteoarthritis After Untreated Anterior Meniscal Root Tears: An In Vivo Animal Study
Authors: Steineman Brett D. , LaPrade Robert F. , Santangelo Kelly S. , Warner Brent T. , Goodrich Laurie R. , Haut Donahue Tammy L.
Published: April 2017

Background:

Meniscal root tears cause menisci and their insertions to inadequately distribute loads and potentially leave underlying articular cartilage unprotected. Untreated meniscal root tears are becoming increasingly recognized to induce joint degradation; however, little information is known about anterior meniscal root tears and how they affect joint tissue.

Purpose:

To observe the early degenerative changes within the synovial fluid, menisci, tibial articular cartilage, and subchondral bone after arthroscopic creation of untreated anterior meniscal root tears.

Study Design:

Controlled laboratory study.

Methods:

Anterolateral meniscal root tears were created in 1 knee joint of 5 adult Flemish Giant rabbits, and anteromedial meniscal root tears were created in 4 additional rabbits. The contralateral limbs were used as nonoperated controls. The animals were euthanized at 8 weeks postoperatively; synovial fluid was aspirated, and tissue samples of menisci and tibial articular cartilage were collected and processed for multiple analyses to detect signs of early degeneration.

Results:

Significant changes were found within the synovial fluid, meniscal tissue, and tibial subchondral bone of the knees with anterior meniscal root tears when compared with controls. There were no significant changes identified in the tibial articular cartilage when comparing the tear groups with controls.

Conclusion:

This study demonstrated early degenerative changes within the synovial fluid, menisci, and tibial subchondral bone when leaving anterior meniscal root tears untreated for 8 weeks. The results suggest that meniscal tissue presents measurable, degenerative changes prior to changes within the articular cartilage after anterior meniscal root tears. Anterior destabilization of the meniscus arthroscopically may lead to measurable degenerative changes and be useful for future in vivo natural history and animal repair studies.

Clinical Relevance:

The present study is the first to investigate various tissue changes after anterior meniscal root tears of both the medial and lateral menisci. The results from this study suggest that degenerative changes occur within the synovial fluid, meniscus, and tibial subchondral bone prior to any measurable changes to the tibial articular cartilage. Further studies should expand on this study to evaluate how these components continue to progress when left untreated for long periods.

Background

Forests provide an essential resource that support the livelihoods of an estimated 20% of the global population. Forests are thought to serve in three primary roles to support livelihoods: subsistence, safety nets, and pathways to prosperity. While we have a working understanding of how poor people depend on forests in individual sites and countries, much of this evidence is dispersed and not easily accessible. Thus, while the importance of forest ecosystems and resources to contribute to poverty alleviation has been increasingly emphasized in international policies, conservation and development initiatives and investments—the strength of evidence to support how forests can affect poverty outcomes is still unclear. This study takes a systematic mapping approach to scope, identify and describe studies that measure the effect of forest-based activities on poverty outcomes at local and regional scales. This effort builds upon an existing systematic map on linkages between conservation and human well-being in order to make this process more efficient. We will conduct a refined and updated search strategy pertinent to forests-poverty linkages to glean additional evidence from studies outside the scope of the original map. Results of this study can be used for informing conservation and development policy and practices in global forest ecosystems and highlight evidence gaps where future primary studies and systematic reviews can add value.

Methods

We build upon the search strategy outlined in McKinnon et al. (Environ Evid 1–25, 2016) and expand our search to cover a total of 7 bibliographic databases, 15 organizational websites, 8 existing systematic reviews and maps, and evidence gap maps, and solicit key informants. All searches will be conducted in English and encompass all nations. Search results will be screened at title, abstract, and full text levels, recording both the number of excluded articles and reasons for exclusion. Full text assessment will be conducted on all included article and extracted data will be reported in a narrative review that will summarize trends in the evidence, report any knowledge gaps and gluts, and provide insight for policy, practice and future research. The data from this systematic map will be made available as well, through an open access, searchable data portal and visualization tool.

Nearly half of all undergraduates are enrolled at community colleges (CCs), including the majority of U.S. students who represent groups underserved in the sciences. Yet only a small minority of studies published in discipline-based education research journals address CC biology students, faculty, courses, or authors. This marked underrepresentation of CC biology education research (BER) limits the availability of evidence that could be used to increase CC student success in biology programs. To address this issue, a diverse group of stakeholders convened at the Building Capacity for Biology Education Research at Community Colleges meeting to discuss how to increase the prevalence of CC BER and foster participation of CC faculty as BER collaborators and authors. The group identified characteristics of CCs that make them excellent environments for studying biology teaching and learning, including student diversity and institutional cultures that prioritize teaching, learning, and assessment. The group also identified constraints likely to impede BER at CCs: limited time, resources, support, and incentives, as well as misalignment between doing research and CC faculty identities as teachers. The meeting culminated with proposing strategies for faculty, administrators, journal editors, scientific societies, and funding agencies to better support CC BER.
Reinventing the Pre-Tang Tradition: Compiling and Publishing Pre-Tang Poetry Anthologies in Sixteenth-Century China
Authors: Chen Jing
Published: April 2017

This article examines how the making of pre-Tang poetry anthologies in sixteenth-century Ming China led to a reinvention of the pre-Tang poetic tradition. From the Zhengde period 正德 (1506–21) well into the Wanli reign 萬曆 (1573–1620), the compilation and publication of new pre-Tang poetry anthologies saw a dramatic increase, making the anthologizing practices in the 1500s crucial to understanding the pre-Tang tradition. Through a study of paratextual elements (book titles, tables of contents, prefaces, postscripts, etc.) in twenty-two pre-Tang poetry anthologies compiled in the 1500s, this article identifies three types of anthologizing practices. By employing quantitative and network analysis, the author hopes to historicize these practices, investigate the motivations for the anthologies, and explore their citation networks. These anthologizing practices, I conclude, gradually transformed the classification principles of previous anthologies, expanded the scope of canonized anthologies, and established a distinct pre-Tang tradition by the end of the sixteenth century.
Gendering the Planchette: Female Writer Qian Xi's (1872–1930) Spiritual World
Authors: Wang Yanning
Published: April 2017

Fuji (wielding the planchette, or spirit writing) was in vogue among Ming-Qing literati, and its influence extended into modern times. Existing studies focus on this popular divination itself or on men's writings related to this practice. This article, instead, explores the poetry and prose of a female writer, Qian Xi, and her writing activities associated with this divination. Qian claims that the spirits she communicated with include several female immortals and her deceased husband. Some of the questions the author explores are: What are the characteristics of Qian's writings? What inspired Qian to participate in spirit writing? What role did this practice play in Qian's life and writing? Regarding the emotions, thoughts, and works of Qian, what types of information can spirit writing and corresponding poetic and prosaic compositions provide? Instead of simplifying and disregarding the ritual of wielding the planchette as bizarre, superstitious, or even mad, the author argues that it played a meaningful role in shaping Qian's literary images and enhancing her literary productivity. More important, Qian Xi's strategies of using spirit writing to stimulate her literary creations was significant in meeting her emotional needs, highlighting her identity as a talented woman, and demonstrating the worth of her very existence.
School Bus Routing with Stochastic Demand and Duration Constraints

Published: April 2017

The school bus routing problem (SBRP) is crucial because of its impact on economic and social objectives. A single bus is assigned to each route, picking up students and arriving at the school within a specified time window. SBRP aims to find the fewest buses needed to cover all of the routes while minimizing the total travel distance and meeting required constraints. We propose a mathematical formulation responding to the overbooking policies applied in a real-world school district. According to our empirical studies, the probability of a student riding a bus varies from 22% to 77%, opening the opportunity to overbook the buses to improve utilization of their capacity. However, SBRP with overbooking has not attracted much attention in previous studies. In this work, overbooking is modeled via chance constrained programming. Additionally, to account for the uncertainty of the total travel time of the buses, a constraint limiting the probability of being late to school is also proposed in this paper. As a result of the NP-hard nature of the problem, a cascade simplification algorithm is proposed to partition the multiple stage SBRP problems into multiple multi-depot and one-school subproblems that are solved sequentially, where the results for one are data inputs for the next. Furthermore, we develop column-generation-based algorithms to solve the scheduling problem, and different instances of the problem are examined. Our computational experiments on a real-world school district demonstrate desirable cost savings in terms of the total number of buses used.
