Discovery Potential for the Neutral Charmonium-LikeZ0(4200)byp-pAnnihilation
Authors: Wang Xiao-Yun , Chen Xu-Rong
Published: May 2015

Inspired by the observation of charmonium-likeZ(4200), we explore the discovery potential of the neutralZ0(4200)production by antiproton-proton annihilation with an effective Lagrangian approach. By investigating thep-p→J/ψπ0process including theZ0(4200)signal and background contributions, it is found that the center of mass energyEc.m.≃4.0–4.5 GeV is the best energy window for searching the neutralZ0(4200), where the signal can be clearly distinguished from background. The relevant calculations not only are helpful to search for the neutralZ0(4200)in the future experiment but also will promote the understanding of the nature and production mechanism of neutralZ0(4200)better.

The main goal in meningioma surgery is to achieve complete tumor removal, when possible, while improving or preserving patient neurological functions. Intraoperative imaging guidance is one fundamental tool for such achievement. In this regard, intra-operative ultrasound (ioUS) is a reliable solution to obtain real-time information during surgery and it has been applied in many different aspect of neurosurgery. In the last years, different ioUS modalities have been described: B-mode, Fusion Imaging with pre-operative acquired MRI, Doppler, contrast enhanced ultrasound (CEUS), and elastosonography. In this paper, we present our US based multimodal approach in meningioma surgery. We describe all the most relevant ioUS modalities and their intraoperative application to obtain precise and specific information regarding the lesion for a tailored approach in meningioma surgery. For each modality, we perform a review of the literature accompanied by a pictorial essay based on our routinely use of ioUS for meningioma resection.

Published: May 2015

We describe the case of a 6.5-year-old girl with central precocious puberty (CPP), which signifies the onset of secondary sexual characteristics before the age of eight in females and the age of nine in males as a result of stimulation of the hypothalamic-pituitary-gonadal axis. Her case is likely related to her adoption, as children who are adopted internationally have much higher rates of CPP. She had left breast development at Tanner Stage 2, adult body odor, and mildly advanced bone age. In order to halt puberty and maximize adult height, she was prescribed a gonadotropin releasing hormone analog, the first line treatment for CPP. She was administered Lupron (leuprolide acetate) Depot-Ped (3 months) intramuscularly. After her second injection, she developed swelling and muscle pain at the injection site on her right thigh. She also reported an impaired ability to walk. She was diagnosed with muscle fibrosis. This is the first reported case of muscle fibrosis resulting from Lupron injection.
Metastatic Uterine Leiomyosarcoma Involving Bilateral Ovarian Stroma without Capsular Involvement Implies a Local Route of Hematogenous Dissemination
Authors: Dandapani Monica , Seagle Brandon-Luke L. , Abdullah Amer , Hatfield Bryce , Samuelson Robert , Shahabi Shohreh
Published: May 2015

Uterine sarcomas spread via lymphatic and hematogenous dissemination, direct extension, or transtubal transport. Distant metastasis often involves the lungs. Ovarian metastasis is uncommon. Here we present an unusual case of a large, high-grade uLMS with metastatic disease internal to both ovaries without capsular involvement or other abdominal diseases, and discovered in a patient with distant metastases to the lungs, suggesting likely hematogenous dissemination of uLMS to the ovaries in this case. Knowledge of usual uLMS metastases may influence surgical management in select cases.
GELATINOUS FIBRES ARE NOT PRODUCED IN RESPONSE TO INDUCED STRESSES IN EPHEDRA
Authors: Montes Monica M. , Ewers Frank W. , Bobich Edward G.
Published: May 2015

Gelatinous fibres (g-fibres) differ from most fibres in that the innermost layer of their secondary cell wall is rich in cellulose and poor in lignin. G-fibres are often produced in response to gravitational and mechanical stresses in the roots, stems, and leaves of angiosperms, with their main function being the reorientation or contraction of these organs. G-fibres also occur in the three genera (Ephedra, Gnetum, and Welwitschia) of the Gnetales, making them the only known gymnosperms with g-fibres in their shoots. The shrubby species E. aspera and E. viridis were studied to determine the function and cues for production of g-fibres in the genus. It was hypothesized that E. aspera and E. viridis would produce g-fibres as a response to gravitational and internal stresses due to downward displacement (bending). Total number of g-fibres and number of g-fibres per area did not differ between displaced and untreated (control) stems of E. aspera. For the younger stems of E. viridis, control stems had more g-fibres than displaced stems, indicating that the production of additional g-fibres in control stems may be a response to wind or other perturbations. For both species, the oldest stems studied had the lowest g-fibre frequency, suggesting that little to no new g-fibres were produced as the stems aged, regardless of treatment. Furthermore, there were no other indications of reaction anatomy (asymmetry of phloem, compression wood, etc.) for E. aspera or E. viridis. These results and the cell wall composition of the fibres, especially those in the cortex, call into question whether the fibres of shrubby Ephedra are typical g-fibres.
Weeding the nettles III: Named nonsense versus named morphotypes in European Urtica dioica L. (Urticaceae)
Authors: Grosse-Veldmann Bernadette , Weigend Maximilian
Published: May 2015

Urtica dioica L. in its wider sense is reported from nearly all temperate zones of the world, from throughout Eurasia, from North America and South America, from S Africa and New Zealand. In Europe, over 70 infrasubspecific names referable to the widespread and often weedy U. dioica subsp. dioica have been used in one form or another; over 40 of them are formally described. Many of these names are invalid and/or superfluous. However, several identifiable morphotypes can be found, which are stable in cultivation and usually occur in several different regions of Europe and/or are characterized by some type of habitat preference. These morphotypes in their most characteristic expression are quite well differentiated, but are connected by a continuous series of intermediates in nature. As a working hypothesis we here propose the tentative recognition of the following five morphotypes: U. dioica subsp. dioica var. dioica, -var. hispida, -var. sarmatica, -var. holosericea, and -var. glabrata. A characterization of each morphotype and corresponding synonyms are presented here based on extensive field studies, literature and herbarium studies and cultivation of material. Lecto-and neotypes are designated where necessary for some of the more important names.

Published: May 2015

The phytogeographical regions and sub-regions of Australia are revised in light of new data from a recent analysis by González-Orozco, Ebach et al. (2014). The new revision includes two new regions, Northern regio nova and Northern Desert regio nova, and five new sub-regions, Nullarbor sub-regio nova, Central Desert sub-regio nova, Great Sandy Desert Interzone sub-regio nova, Central Queensland sub-regio nova and, Southwestern sub-regio nova. This new revised version of the phytogeographical regions and sub-regions of Australia’s land plants provides an updated classification based on historical nomenclature. The analysis by González-Orozco, Ebach et al. (2014) is a biogeographically centered classification that generated the first exclusively taxonomic regionalisation of Australia’s land plants, used here to update the ABA phytogeographical regions.

Authors: Troisi Jordan D. , Leder Sadie , Stiegler-Balfour Jennifer J. , Fleck Bethany K. B. , Good Jessica J.
Published: May 2015

To date, research has not examined the influence of mentorship on the teaching effectiveness of Early Career Psychologists (ECPs). We sought to fill this void by conducting a national survey of 122 ECPs assessing the presence or absence of three types of ECP mentors (i.e., in their department, in another department at their university, or another self-selected mentor) as well as the successes and challenges associated with working with those mentors. Overall, ECPs viewed relationships with mentors quite favorably, and mentorship was positively related to more effective teaching activities and adherence to model teaching criteria. Implications for future research on the study of mentorship among ECPs and how junior and senior faculty can benefit from these findings are discussed.
Effects of Online Reciprocal Teaching on Reading Strategies, Comprehension, Self-Efficacy, and Motivation
Authors: Huang Ching-Ting , Yang Shu Ching
Published: May 2015

This study examines the effects of two types of online remedial reading interventions on the reading strategy and comprehension, motivational beliefs, and self-efficacy of 36 low-achieving students (explicit teaching before reciprocal teaching [ET-RT] vs. direct instruction [DI]). We designed a 10-unit online remedial English reading program based on the theoretical framework of the ET-RT model developed by Palincsar and associates. The study investigates the patterns of teacher modeling in both groups and interactive dialogue in the ET-RT group. Students' experiences and perceptions of reading interventions are also explored. The study reveals that implementing ET-RT significantly improved student reading comprehension and strategies and self-efficacy compared with DI. Triangulation with a survey indicated that ET-RT instruction reduced learners' anxiety about learning English and increased interest in reading. Moreover, the ET-RT learners had a better command of reading strategies than the DI learners. However, the qualitative evaluation of learner performance revealed that both groups showed moderate satisfaction and that most students accepted the interventions. ET-RT learner excerpts highlight the importance and usefulness of explicit reading strategy instruction. These findings indicate that both ET-RT and DI instruction have value. However, the finding that ET-RT outperformed DI suggests the need to reconsider the design and implementation of remedial English reading instruction.
Automated LSA Assessment of Summaries in Distance Education

Published: May 2015

A latent semantic analysis-based automated summary assessment is described; this automated system is applied to a real learning from text task in a Distance Education context. We comment on the use of automated content, plagiarism, text coherence measures, and word weights average and their impact on predicting human judges summary scoring. A first regression analysis showed the independence of interparagraph coherence with respect to superficial text variables, advising its inclusion in a general regression model, along with content, plagiarism measures. The final regression model explains a considerable degree of variability in human judgment of summaries. Finally, we discuss several methodological implications and further applications of the automated summary scoring technique developed in this study.
Indeterminacy, Complexity, Technocracy and the Reform of International Corporate Taxation
Authors: Picciotto Sol
Published: May 2015

Recent public concerns and publicity about the extent of tax avoidance by some of the largest and most respected transnational corporations have prompted numerous parliamentary inquiries and intergovernmental initiatives. Among the questions raised during hearings in the UK House of Lords on 11 June 2013 were whether such avoidance could be more effectively prevented either by a reduction in the complexity of the rules, or by a more aggressive interpretation of those rules by tax authorities. These questions raised issues concerning the complexity and interpretation of law, which received interestingly different responses from the academics to whom they were posed, and they merit closer examination, which is the aim of this article. The article begins by discussing some types of complexity, then considers how these are rooted in the indeterminacy of legal language and finally discusses the sociology and politics of the interpretive communities concerned. The main part applies this analysis to the historical development of international tax rules, seen in the context of these current pressures and initiatives for reform of international corporate taxation.
Corporate Social Responsibility and Tax Planning
Authors: Gribnau Hans
Published: May 2015

Taxpayers have to plan their tax affairs to plan their life or develop their business strategy. Often tax planning is encouraged and intended by tax legislation but sometimes it is not. By way of tax incentives, the tax legislator often tries to steer citizens’ behaviour to achieve all kind of policy goals. This way the tax legislator stimulates taxpayers to adopt a calculating attitude towards the tax system, breeding a rule-based mindset focused on tax planning. This rule focus crowds out ethics. Taxpayers turn around the rules to their advantage. The tax legislator usually reacts with refined or new rules that add to the existing complexity of tax law. Companies endorsing corporate social responsibility (CSR) accept ethical obligations beyond compliance with the law. It is argued that these companies should agree that the interpretation and use of tax rules are based on a moral choice that rules out strictly complying with the letter of the law. CSR companies should even take one more step in endorsing the view that tax is a body of rules, which itself is grounded in principles that make up the internal morality of law. Therefore, they should take these principles seriously when engaging in tax planning.
Between Politics and Discipline: Gender Studies in an Institutional Setting
Authors: Sreenivas Deepa
Published: May 2015

This article draws on the classroom experiences of the author to reflect on the pedagogic shifts in Gender Studies. Along with its recognition as being a ‘proper’ discipline and the need to have Gender Studies at all levels in a university, comes the question of legitimacy. It must now be defined by boundaries, protocols and methodologies. I look at the manner in which these conditions unfold in two settings—in the undergraduate and the research classrooms. In the first context, young, freshly-out-of-school students appear to view Gender Studies as a gender sensitisation programme while in the latter methodological/ empirical certainties often take precedence over the need for analytical probing. In both cases, the initial imagination of the subject as a ‘critical perspective’ across disciplines appears to yield to a more official, programmatic understanding. In my own context, I grapple with the simultaneous visibility and reduction of Women’s/Gender Studies.
Towards a Framework for Forging Links: Exploring the Connections between Women’s Education, Empowerment and Employment
Authors: Pappu Rekha
Published: May 2015

It is a common belief that there are substantial returns on education, both direct and indirect and gainful employment is regarded as one of the expected outcomes of education. However, existing analyses of the employment–unemployment trends in India indicate an inverse relationship between women’s education and employment. Within such a context this article seeks to raise the question of whether the education system can address the problem of educated women withdrawing from the labour force even as attempts are made to transform other structural factors that impinge on the situation. Feminist concerns about empowerment frame this discussion on education and employment.
The Long-term Outlook and Risks in Advanced Countries
Authors: Robinson David
Published: May 2015

This article seeks to provide a broad overview of the long-term growth outlook for advanced countries, taking into account also the impact and legacies of the Great Moderation and the Great Recession. The article explores their role in the global economy going forward and the key policy challenges that they face, with a particular emphasis on the implications for developing countries. The starting point for this analysis is a brief summary of the short-term outlook for advanced countries and the likely legacies of the Great Recession. Then, the article sets out a baseline scenario for long-term global growth, drawing on the results of the Centennial long-term growth model. In this scenario, global trade would significantly increase and the gap in size in financial markets in emerging and advanced economies would narrow. To achieve these outcomes, advanced economies face challenges, including demographic transition, slow growth, and large fiscal imbalances. To mitigate these risks, advanced countries will need to accelerate and consolidate structural reforms and develop credible medium-term fiscal frameworks. To a certain extent, developing countries need to reduce their reliance on advanced economies to achieve the outcomes described in the baseline scenario; they should boost domestic sources of growth and strengthen their economies against external shocks. This does not preclude international cooperation, however. While some slowdown in financial globalization in particular may be necessary and appropriate to reduce risks to financial stability, there are significant risks that this could go too far. This, in turn, can only reinforce the importance of strengthened multilateral cooperation in the long term.

Defining the concept of commodity production
Authors: Patnaik Prabhat
Published: May 2015

Commodity production has been usually taken in the sense of any production organised for sale, even if this sale be for the local market and local consumption. Such a simplistic notion is, however, not really that of Marx, who had in view sale for distant markets with whose actual functioning the producer had no contact qua producer. It was the rise of such a market that really created the ground for both colonialism and capitalism.

The Bear in the Grave: Exploitation of Top Predator and Herbivore Resources in First Millennium Sweden—First Trends from a Long-Term Research Project
Authors: Lindholm Karl-Johan , Ljungkvist John
Published: May 2015

This paper focusses on animal remains associated with archaeological contexts dated to the middle and later phases of the Scandinavian Iron Age, which corresponds to the first millennium AD. The main question to be addressed is whether this record can be used for identifying human impact on certain animal populations for modelling faunal exploitation and interregional trade. In the first part of the paper, we undertake a detailed inventory of animal finds recorded in published excavation reports, research catalogues, and in existing databases maintained primarily by the Historical Museum in Stockholm. We compare the chronological pattern identified in the burial assemblages with a chronological sequence retrieved from pitfall hunting systems located in the Scandinavian inland region. The chronologies of the animal finds from burials and the pitfall systems are then compared with dated pollen-analytical sequences retrieved in the inland region and additional archaeological assemblages, such as graves and hoards of Roman coins. In our discussion, we outline an interregional model of faunal exploitation between AD 300 and 1200, including the possible location of hunting grounds and end-distribution areas for animal products. The paper provides deeper insights into the burial record of the middle Iron Age, arguing for the need for broader interregional approaches, and focussed archaeological research in the inland regions of Scandinavia.
Patients with migraine are right about their perception of temperature as a trigger: time series analysis of headache diary data
Authors: Yang Albert C. , Fuh Jong-Ling , Huang Norden E. , Shia Ben-Chang , Wang Shuu-Jiun
Published: May 2015

Background

Researches to date on the association between headache and weather have yielded inconsistent results. Only a limited number of studies have examined the clinical significance of self-reported weather sensitivity. This study aimed to identify the difference in the association of headache with temperature between migraine patients with and without temperature sensitivity.

Methods

66 migraine patients (75.8 % female; mean age 43.3 ± 12.9 years) provided their 1-year headache diaries from 2007 to a headache clinic in Taipei, Taiwan. 34 patients (51.5 %) reported sensitivity to temperature change but 32 (48.5 %) did not. Time series of daily headache incidence was modeled and stratified by temperature sensitivity. Empirical mode decomposition was used to identify temporal weather patterns that were correlated to headache incidence, and regression analysis was used to examine the amount of variance in headache incidence that could be explained by temperature in different seasons.

Results

Among all migraine patients, temperature change accounted for 16.5 % of variance in headache incidence in winter and 9.6 % in summer. In winter, the explained variance increased to 29.2 % among patients with temperature sensitivity, but was not significant among those without temperature sensitivity. Overall, temperature change explained 27.0 % of the variance of the mild headache incidence but only 4.8 % of the incidence of moderate to severe headache during winter.

Conclusions

This diary-based study provides evidence to link the perception of temperature sensitivity and headache incidence in migraine patients. Those who reported temperature sensitivity are more likely to have headache increase during the winter, particular for mild headaches.
Left-behind children and return migration in China
Authors: Démurger Sylvie , Xu Hui
Published: May 2015

This paper examines how left-behind children influence migration duration in China. We first present a simple illustrative model that incorporates economic and non-economic motives to migration duration. Using individual data from a survey carried out in Wuwei county (Anhui province) in 2008, we find that migrant parents of children in primary school tend to delay their return, a result we interpret as illustrating the need for migrant parents to accumulate money for their offspring’s education. In contrast, parental time appears substitutable by coresiding grandparents who contribute to delay the parents’ return, especially mothers, when they have children below the age of 12.

Shot- and angle-domain wave-equation traveltime inversion of reflection data: Synthetic and field data examples
Authors: Zhang Sanzong , Luo Yi , Schuster Gerard
Published: May 2015

Full-waveform inversion requires the accurate simulation of the dynamics and kinematics of wave propagation. This is difficult in practice because the amplitudes cannot be precisely reproduced for seismic waves in the earth. Wave-equation reflection traveltime tomography (WT) is proposed to avoid this problem by directly inverting the reflection-traveltime residuals without the use of the high-frequency approximation. We inverted synthetic traces and recorded seismic data for the velocity model by WT. Our results demonstrated that the wave-equation solution overcame the high-frequency approximation of ray-based tomography, was largely insensitive to the accurate modeling of amplitudes, and mitigated problems with ambiguous event identification. The synthetic examples illustrated the effectiveness of the WT method in providing a highly resolved estimate of the velocity model. A real data example from the Gulf of Mexico demonstrated these benefits of WT, but also found the limitations in traveltime residual estimation for complex models.
LES-PDF Modeling of Blowout Analysis in Slit Bluff-Body Stabilized Flames
Authors: Liu Xiao , Zheng Hongtao , Yang Jialong , Li Yajun
Published: May 2015

This work presents a numerical study of a premixed turbulent combustion behind slit bluff-body by Large Eddy Simulation (LES) and Composition PDF Transport (C-PDF) with detailed mechanism, the main focus is placed on the blowout analysis. Different flow and combustion structure is observed, two different sizes recirculation zones (RZ) are formed because of the gap flow; a V shape high temperature area exists behind slit bluff-body as a pilot flame. The blowout process was analyzed by time sequence of instantaneous temperature fields. It can be seen as the process of two small bluff-bodies strongly coupled by the gap flow. Both RZs began to shed a von Karman (vK) vortices street and the large vortex shedding from big RZ will swallow the small one from small RZ and form a larger vortex. Localized extinction exists both along the shear layer and behind the gap. The small RZ will blowout firstly once the shear layer and gap extinction meet, and then will the big RZ. The predicted blowout limits indicate that the blowout limit can be significantly improved at an optimal ratio of slit width. In addition, the influence of inlet velocity and temperature was predicted, the results show that enough energy produced by the V shape high temperature area to sustain the flame is the most important factor on the performance of the blowout.
Effects of Energy Deposition Characteristics on Localised Forced Ignition of Homogeneous Mixtures
Authors: Patel Dipal , Chakraborty Nilanjan
Published: May 2015

The effects of the characteristic width of the energy deposition profile and the duration of energy deposition by the ignitor on localised forced ignition of stoichiometric and fuel-lean homogeneous mixtures have been analysed using simplified chemistry three-dimensional compressible Direct Numerical Simulation (DNS) for different values of root-mean-square turbulent velocity fluctuation. The localised forced ignition is modelled using a source term in the energy transport equation, which deposits energy in a Gaussian manner from the centre of the ignitor over a stipulated period of time. It has been shown that the width of ignition energy deposition and the duration over which ignition energy is deposited have significant influences on the success of ignition and subsequent flame propagation. An increase in the width of ignition energy deposition (duration of energy deposition) for a given amount of ignition energy has been found to have a detrimental effect on the ignition event, which may ultimately lead to misfire. Moreover, an increase in u′ gives rise to augmented heat transfer rate from the hot gas kernel, which in turn leads to a reduction in the extent of overall burning for both stoichiometric and fuel-lean homogeneous mixtures but the detrimental effects of high values of u′ on localised ignition are particularly prevalent for fuel-lean mixtures.
A New Perspective on the Flame Describing Function of a Matrix Flame
Authors: Heckl Maria
Published: May 2015

This paper considers a fundamental thermoacoustic test rig developed by Noiray (“Linear and nonlinear analysis of combustion instabilities, application to multipoint injection systems and control strategies”, PhD thesis, École Centrale Paris, 2007) and models it with an entirely analytical approach. The test rig is treated as a system of two coupled elements: an acoustic resonator and a flame with oscillating rate of heat release. We describe the acoustics of the combustion rig in terms of modes, and derive a governing equation for one such mode. This turns out to be the equation for a damped harmonic oscillator, forced by the heat release rate from the flame. In order to model the heat release rate, and in particular its nonlinear aspects, we develop a generalised nτ-law with amplitude-dependent coefficients and multiple time-lag. The coefficients are determined from Noiray's measured flame describing function. Stability predictions are made by evaluating the sign of the damping coefficient in the governing equation. These predictions are in excellent qualitative agreement with the measured stability behaviour. Finally, the physical mechanisms of the amplitude-dependence are explored.

Published: May 2015

Implementation strategies for using oral nutritional supplements (ONS) in patients with stages 4-5 chronic kidney disease (CKD) are lacking in the UK and current international recommendations 1 are not tailored to the dietetic-led nutrition services prominent in the UK. A recent meeting of the Renal Nutrition Group (RNG) of the British Dietetic Association (BDA) identified a need for clarity on the use of ONS in these patients and as a result a group of seven renal dietitians, together with a general practitioner, met to discuss and reach agreement on a simple step-by-step consensus algorithm to guide the appropriate use of ONS in patients with stages 4-5 CKD.

Statin-induced myopathy following the use of a calcium channel blocker in a transplant patient
Authors: Coleman Adrian , Chai Mee Onn
Published: May 2015

Adrian Coleman and Mee Onn Chai discuss the case of a transplant recipient who developed myopathy as a result of a drug interaction between a calcium channel blocker (CCB) and a common cholesterol-lowering medication. They also describe the use of CCBs in the management of hypertension.

Case study

Mr SL is a 45-year-old Caucasian man with a body mass index of 24 kg/m2. His primary diagnosis for renal failure is hypertension, but he also has familial hypercholesterolaemia. He received a kidney transplant 6 months ago after spending a year on haemodialysis, and his transplanted kidney was considered a good immunological match, with a low risk of rejection. Mr SL's kidney function was stable with an estimated glomerular filtration rate (eGFR) of 45 ml/min/1.73 m2. The aim for his tacrolimus concentrations were between 4–7 mcg/l and his pre-dose level was 6 mcg/l. At his review, it was identified that his average blood pressure (BP) reading was 160/90 mmHg and the transplant consultant added nifedipine modified-release tablets (10 mg, twice-daily) to his BP medications ( Table 1 ). Four weeks later, Mr SL contacted the transplant team when he felt generally unwell with fatigue and muscle pain. Following blood tests, it was identified that his eGFR decreased to 30 ml/min/1.73 m2 and his tacrolimus trough level was 10 mcg/l. His C-reactive protein (CRP) was normal, white blood cell count was not elevated, and viral screen was negative. He did not have a temperature, his BP was 130/85 mmHg, and his creatinine kinase (CK) was elevated at 3000 mmol/l (normal range 40–100 mmol/l). The team's conclusion was that he was suffering with statin-induced myopathy, caused by a combination of interactions between nifedipine, tacrolimus and high-dose simvastatin. Nifedipine and tacrolimus were discontinued and repeat tacrolimus levels were requested for 1 weeks' time along with a review by one of the medical team. At the review, Mr SL claimed the muscle pain was resolving, and following another blood test, his CK reduced to 1300 mmol/l, eGFR returned to his baseline of 45 ml/min/1.73m2 and his tacrolimus level was back to within his normal range. His BP remained high at 155/90 mmHg and so it was decided to start amlodipine 5 mg once-daily. The team agreed to review the need for another cholesterol-lowering agent once the symptoms had completely resolved and his CK was within normal limits.

Phatic Traces: Sociality in Contemporary Japan
Authors: Nozawa Shunsuke
Published: May 2015

Widely recognized as a social problem in Japan, kodokushi (solitary death) stereotypically happens when old people living alone, detached from kin and neighbors, die alone without being noticed immediately, leaving the body to decompose. Reorganizing Japanese discourses of kinship, locality, and other modalities of “connection” ( en ), practices and projects concerning solitary death articulate an emergent fantasy of sociality. I analyze this fantasy as an ideology of communication that draws upon idioms of “contact,” or phaticity: “touching-together” ( fureai ), “connecting” ( tsunagari ), and so on. Due recognition of such an ideology reveals different ways in which sociality is understood in Japan today. Reclaiming the concept of phaticity through a more explicit theoretical metalanguage, I offer an exploration of the cultural concept of en to suggest that the condition of solitude transpires in an interstice between two qualitatively different chronotopes of sociality.
“By the Time I Get to Arizona”: Citizenship, Materiality, and Contested Identities Along the US–Mexico Border
Authors: De León Jason , Gokee Cameron , Schubert Ashley
Published: May 2015

Each year hundreds of thousands of people attempt to enter the United States from Mexico without authorization by crossing the Sonoran Desert on foot or using false identification at ports of entry. During this crossing process, people actively construct, contest, and obfuscate a multiplicity of identities through various forms of material culture including clothing, hygiene and cosmetic products, and identification paperwork. These identities include undocumented border crosser, false citizens of various countries (e.g., the US and Mexico), and people with no identification. Those charged with keeping non-citizens out of the US (i.e., Border Patrol) also rely on various forms of material culture that both reflect and construct perceptions of migrants as non-citizens with no federal rights or protections. In this article, we highlight the material correlates of different migrant and law enforcement behaviors and identities, and discuss the ways in which they impact the experiences of border crossers en route. Drawing on Agamben’s “state of exception,” we argue that the concepts of citizenship, sovereignty, and materiality are key to understanding how migrants both resist and succumb to the power of the state to exclude them.
Mediating Disjunctures of Time: Ancestral Chronotopes in Ritual and Media Practices
Authors: Eisenlohr Patrick
Published: May 2015

In this article, I approach regimes of time as a medial question, examining the interplay of different temporalities in ritual and media practices among Hindus in Mauritius and Twelver Shi’ite Muslims in Mumbai. These interactions consist of fluctuations between modernist linear modes of time and suspensions of the distinctions of past, present, and future as the performative outcome of certain ritual practices. Drawing on a broad notion of media and mediality, I trace the links between shifting states in the functioning of media and the oscillation between the different notions of temporality examined. Analyzing their interconnectedness in ancestral politics and religious mobilizations, I show how media practices provide ways to navigate the heterochronies that characterize such politics and activism.
Basic Kinship Terms: Christian Relations, Chronotopic Formulations, and a Korean Confrontation of Language
Authors: Harkness Nicholas
Published: May 2015

This ethnographic analysis of the pragmatic links among forms of address, honorifics, and narratives of spiritual maturity clarifies a conflict between two Christian models of social change in South Korea: absolute social rupture and transcendence, and progressive shifts in social orientation and institutional self-location. The focus is on a Protestant proposal for all Korean Christians to address one another with the terms hyŏngje-nim (brother) and chamae-nim (sister). While these terms promised to combine the intimacy of siblinghood with the clear marking of Christian status, they generally had the interactional effect of establishing distance where there was to be closeness and lowering where there was to be esteem. Furthermore, a simplification of address to these two basic kinship terms threatened to establish an ascetic mode of pragmatics that would override the intricate formal coding and indexing of status differentiation by the enregistered honorifics of Korean. Combined, these limited forms of address and the severe restriction of social deixis generated yet further conflict between different chronotopic formulations of social relations, namely between the narrative timespace internal to specific kinds of Korean social relations, and the generalized external narrative timespace of modern Korean Christian society at large.
Students’ Food Acquisition Struggles in the Context of South Africa: The Fundamentals of Student Development
Authors: Dominguez-Whitehead Yasmine
Published: May 2015

This article situates food at the heart of the fundamentals of student development, based on qualitative case study research. Food acquisition and food-related struggles in the context of the South African university are examined. Three overarching themes emerged from the analysis of the data, and are discussed in detail: depletion of food funds, acquiring food on campus, and awareness of others’ food struggles. The findings suggest that students struggling to acquire food are dominated by food acquisition issues and that inaccessibility of food on campus has a potentially detrimental impact on student development and involvement on campus.
Finding a Fit: Understanding Black Immigrant Students’ Engagement in Campus Activities
Authors: Griffin Kimberly A. , McIntosh Kadian L.
Published: May 2015

This qualitative study examined how both racial and ethnic identity shaped 23 Black immigrants students’ patterns of engagement. Students more often chose to meaningfully engage in culturally based organizations, differentiating between groups with a racial and ethnic focus. Whereas many students perceived the unique benefits of ethnically focused groups, some students, particularly those who were not first generation immigrants, found these groups exclusionary. Varying levels of complexity in meaning making influenced students’ decision making about which groups to join and whether certain identities were perceived to be in conflict.
A Cocktail of Extracurricular Activities (ECAs): Different ECA Combinations and Their Association With Heavy Drinking in Two College Cohorts
Authors: Martinez Julia A. , Johnson Douglas N. , Jones Jane A.
Published: May 2015

The activities that students participate in are important to college life and outcomes. With regard to the problem outcome of heavy drinking, some activities pose risks (e.g., fraternity/sorority life) and others are protective (e.g., religious groups), yet students often participate in multiple activities. We estimated the odds of frequent heavy drinking as a function of all 2-, 3-, and 4-activity combinations (out of 10 total activities) in 2 separate college cohorts of 1,005 and 592 students. Findings showed that activities indeed combine to form informative high- and low-risk groups for intervention and advising, adding additional insight into the theory of college involvement.
Cyber Aggression Among College Students: Demographic Differences, Predictors of Distress, and the Role of the University
Authors: Bauman Sheri , Baldasare Angela
Published: May 2015

Using the Cyberbullying Experiences Survey, we collected data from 1,114 undergraduate students at a large public Southwestern university. In addition to inquiring about students’ experiences with bullying, we inquired about the level of distress and the digital medium used. Results showed differences in types of experiences and level of distress by demographic groups (members of Greek organizations, LGBT students), and obtained students’ perspectives on the role of the university in curbing this behavior. The strongest predictor of the level of distress was the use of Facebook to perpetrate the bullying. Implications of findings are discussed.
The Role of Achievement Motivations and Achievement Goals in Taiwanese College Students’ Cognitive and Psychological Outcomes
Authors: Chen Su-Yen , Lu Luo
Published: May 2015

This study explores how motivational factors are associated with Taiwanese college students’ cognitive, personal, and social development by incorporating both relatively global, static self-attributes, such as social-oriented achievement motivation and individual-oriented achievement motivation, which are considered to be culturally balanced conceptions of achievement motivation for Chinese people, and more domain-specific self-attributes, such as achievement goals, which are widely adopted internationally. The findings suggest that institutions can encourage students to set their own motivational goals, rather than adopting goals set by the family or the clan, and to focus on self-referenced competence development and personal improvement.
A Qualitative Examination of Multiracial Students’ Coping Responses to Experiences with Prejudice and Discrimination in College
Authors: Museus Samuel D. , Sariñana Susan A. Lambe , Ryan Tasha Kawamata
Published: May 2015

National data indicate that multiracial individuals comprise a substantial and growing proportion of the US population, but this community is often invisible in higher education research and discourse. This study aims to increase knowledge of mixed-race students in higher education by examining the ways in which they cope with experienced prejudice and discrimination in college. Findings indicate that multiracial college students cope with prejudice and discrimination by educating others about multiracial issues, utilizing support networks, embracing fluidity of multiracial identity, and avoiding confrontation with sources of prejudice and discrimination. Implications for research and practice are discussed.
Relations of Abortion: Crip Approaches to Reproductive Justice
Authors: Jarman Michelle
Published: May 2015

The article challenges the politically reductive ways that disability is leveraged by both antiabortionists and pro-choice supporters—on one side to claim “protection” of all life, and on the other to use disability as a crucial justification for abortion rights. It centers disability for two reasons: first, to demonstrate the deep connections of disability to the ongoing political erosion of access to reproductive healthcare services, which disproportionately impacts women of color and economically vulnerable women; and second, to build on recent scholarship suggesting a merging of critical disability and reproductive justice approaches to reconfigure the dominant pro-choice public discourse on abortion. To bring these two approaches closer together, this article focuses on two key elements of the abortion debate—access and autonomy—from a critical disability studies lens. By foregrounding disability approaches to access and critiques of autonomy, the complicated relational concerns of reproduction are brought into focus. Ultimately, it argues that an interconnected relational context provides a more nuanced approach that both supports women’s access to reproductive options and demands an expansion of the political frame based on choice and rights to include valuing and sustaining lives, challenging precarity, and supporting complex reproductive decisions.
