Recover Overnight? Work Interruption and Worker Productivity
Authors: Cai Xiqian , Gong Jie , Lu Yi , Zhong Songfa 
Published: August 2017

This paper investigates the effect of work interruption on workers’ subsequent productivity. We employ a data set of individual productivity and machine conditions, in which each worker faces the chance, on a daily basis, that her machine will break down randomly. Our analysis finds that compared to a workday with smooth production, experiencing a machine breakdown is associated with a 3.3 percentage point decline in the worker’s productivity the following day. We discuss possible explanations for the observed effect, including negative emotions, increased cautiousness in operating the machine, and proficiency loss. Our findings shed light on the importance of understanding and managing interruptions in the workplace, and contribute to a growing literature on the determinants of productivity at the micro level. Data and the online appendix are available at https://doi.org/10.1287/mnsc.2017.2792 . This paper was accepted by John List, behavioral economics.
Multi- and univariate analyses of the weekend effect for elective lower-limb joint replacements
Authors: Briggs WTE , Guevel BLT , McCaskie AW , McDonnell SM 
Published: August 2017

Introduction The weekend effect is a perceived difference in outcome between medical care provided at the weekend when compared to that of a weekday. Clearly multifactorial, this effect remains incompletely understood and variable in different clinical contexts. In this study we analyse factors relevant to the weekend effect in elective lower-limb joint replacement at a large NHS multispecialty academic healthcare centre. Materials and Methods We reviewed the electronic medical records of 352 consecutive patients who received an elective primary hip or knee arthroplasty. Patient, clinical and time-related variables were extracted from the records. The data were anonymised, then processed using a combination of uni- and multivariate statistics. Results There is a significant association between the selected weekend effect outcome measure (postoperative length of stay) and patient age, American Society of Anesthesiologists classification, time to first postoperative physiotherapy and time to postoperative radiography but not day of the week of operation. Discussion We were not able to demonstrate a weekend effect in elective lower-limb joint replacement at our institution nor identify a factor that would require additional weekend clinical medical staffing. Rather, resource priorities would seem to include measures to optimise at-risk patients preoperatively and measures to reduce time to physiotherapy and radiography postoperatively. Conclusions Our findings imply that postoperative length of stay could be minimised by strategies relating to patient selection and access to postoperative services. We have also identified a powerful statistical methodology that could be applied to other service evaluations in different clinical contexts.

Introduction Enhanced recovery programmes (ERPs) reduce patient morbidity and mortality, and provide significant cost savings by reducing length of stay. Currently, no uniform ERP guidelines exist for lower limb arthroplasty in the UK. The aim of this study was to identify variations in ERPs and determine adherence to local policy. Methods Hospitals offering elective total knee arthroplasty (TKA) and total hip arthroplasty (THA) (23 and 22 centres respectively) contributed details of their ERPs, and performed an audit (15 patients per centre) to assess compliance. Results Contrasting content and detail of ERPs was noted across centres. Adherence to ERPs varied significantly (40–100% for TKA, 17–94% for THA). Analysis identified perioperative use of dexamethasone, tranexamic acid and early mobilisation for TKA, and procedures performed in teaching hospitals for THA as being associated with a reduced length of stay. Conclusions This study highlights variation in practice and poor compliance with local ERPs. Given the proven benefits of ERPs, evidence-based guidelines in the context of local skillsets should be established to optimise the patient care pathway.
Action Score Generator (2014)
Authors: Walker Nathan 
Published: August 2017

Abstract
The Action Score Generator is an online writing machine that writes and re-writes an infinite series of performance event scores. The source texts collect together previously performed actions by artist Nathan Walker between 2006 and 2013. The scores are arranged into poetic, six-word-length instructions, aligning performance objects, tasks, verbs and spaces that are reorganized endlessly by a JavaScript code. The Action Score Generator aligns itself with the short poetic texts of Fluxus Event Scores and with rhythms of computational data and visual poetry. An Action Score Generator book is published by IF P THEN Q Press, Manchester, including an Afterword by Mark Leahy entitled ‘An action movie (for NW): Reading time code action’.
School Literacy Practices Closer to Home: the New Challenge of Literacy Learning
Authors: Quintero Luz Mary 
Published: August 2017

Literacy learning/teaching can be an unforgettable experience when it is a joint effort between school and home. There are family literacy practices and traditions that can bring about amazing outcomes whenthey are conjugated with school literacy activities. This article attempts to suggest some possible ways for teachers and parents to work collaboratively to make the journey of becoming literate a much more rewarding path for both children and teachers. The perspectives presented here are based on experiences that some teachers have lived by working with parents, and on some theoretical perspectives. It is an invitation forus, teachers, to reflect upon our literacy practices we promote in our classrooms and think of possible alternatives to make children find reading and writing a meaningful and enjoyable route.
From pre-school to university: student-teachers’ characterize their EFL writing development
Authors: Viáfara Gozález John Jairo 
Published: August 2017

A historical review of approaches used to support students’ writing in English as a foreign or second language, as well as of Colombian teachers’ efforts to guide their pupils’ in this area becomes the starting point for this qualitative research. The study explores the biographical narratives of EFL pre-service teachers from Universidad Pedagógica y Tecnológica de Colombia (UPTC) to describe how they have developed their writing in English. The research reveals the methodological practices to which participants have been exposed from their early schooling until their university education in Colombian institutions, most of them located in Boyacá. Finally, the pedagogical implications seek to provide reflective points for the education of in-service and pre-service teachers at a time when higher standards in students’ foreign language learning are expected.
A novel ceramic tibial component is as safe as its metal counterpart
Authors: Trieb Klemens 
Published: August 2017

Abstract
Failure rates of 2–10% provide evidence for further development in knee arthroplasty. The purpose of our study was to examine the safety of the tibial component of a novel all-ceramic total knee replacement (TKR) (BPK-S Integration ceramic) consisting of BIOLOX®delta ceramic. The standards ISO 14879-1 and ASTM F1800-07 describe the test set-up for the experimental strength verification with a significantly increased maximum load of 5300 N (900 N are required) and post-fatigue burst strength testing. All specimens were able to prove their mechanical strength against fracture in the alternating load test. There was no material fracture in any of the included tibial components. The subsequent post-fatigue burst strength testing revealed the maximum strength against fracture of all specimens. With at least 9.7 kN for size 3 and at least 12.1 kN for size 6, all specimens showed relatively large strength reserves to the stress in the alternating load test. So far we simulated an in vivo lifetime of 10 years for the tibial component. Further studies should be conducted in which longer in vivo lifetimes of the components are simulated to investigate possible fatigue of the used material over a longer period of time.
Undergraduate medical students need more training in craniomaxillofacial surgery: a comparative study between medical and dental students

Published: August 2017

AbstractPurpose:To compare the performance in oral, craniomaxillofacial, and facial plastic surgery (CMF)-specific surgical skills between medical students (MS) and dental students (DS) and hence adjust the current CMF training to student-specific needs. The investigators hypothesized that there would be no performance differences between MS and DS.Methods:The investigators implemented a comparative retrospective item-based analysis of student performance in a CMF-specific objective structured clinical examination (OSCE) from 2008 to 2015. The sample was composed of 1010 MS and 225 DS who completed a standardized CMF training and OSCE. Three OSCE scenarios [management mandible fracture (MMF), management zygomatic fracture (MZF), and structured facial examination (SFE)] were included in the study because learning objectives were equal. Descriptive and bivariate statistics were computed and the p value was set at 0.05.Results:In all of the analyzed OSCE scenarios, DS significantly outperformed MS (MMF p<0.001; MZF p=0.013; SFE p<0.001). DS especially appeared to be better in the correct interpretation of radiological findings (five of seven items, MMF) and the correct allocation of anatomical structures (four of five items, MZF) as well as the symptom-oriented examination of the eye (three of three items, SFE).Discussion and conclusion:DS overall seem to be perform better in typical CMF skills. The reasons for this performance gap could be a more profound knowledge of the facial anatomy as well as a higher awareness for CMF as a related specialty to dentistry. CMF should be included in medical curricula in a larger scale, and possible career paths should be highlighted to MS and DS to raise attraction for the specialty. Further studies should focus on the implementation of modern teaching methods in CMF education.

AbstractThe dielectric barrier discharge (DBD) technique based cylindrical water falling film reactor was used for degrading an azo dye methyl orange (MO). The primary conditions affecting the degradation of methyl orange were systematically investigated. After 30 min plasma treatment, the degradation rate of MO was as high as 93.7% with gas velocity of 300 mL/min and the input energy of 72.5W. The influences of initial pH and conductivity of MO solution were also explored. The results indicated that the optimum pH value was 3.02 and 99.1% removal of MO was achieved within 30 min.

Abstract

Background:
The objective of the study was to evaluate the antidiarrheal and antinociceptive activities of ethanol extract and its chloroform and pet ether fraction of Phrynium imbricatum (Roxb.) leaves in mice.

Methods:
In the present study, the dried leaves of P. imbricatum were subjected to extraction with ethanol, and then it was fractioned by chloroform and pet ether solvent. Antidiarrheal effects were tested by using castor oil-induced diarrhea, castor oil-induced enteropooling, and gastrointestinal transit test. Antinociceptive activity was evaluated by using the acetic acid-induced writhing test and formalin-induced paw licking test.

Results:
The standard drug loperamide (5 mg/kg) showed significant (p<0.001) inhibitory activity against castor oil-induced diarrhea, in which all the examined treatments decreased the frequency of defecation and were found to possess an anti-castor oil-induced enteropooling effect in mice by reducing both weight and volume of intestinal content significantly, and reducing the propulsive movement in castor oil-induced gastrointestinal transit using charcoal meal in mice. The results showed that the ethanol extract of P. imbricatum leaves has significant dose-dependent antinociceptive activity, and among its two different fractions, the pet ether fraction significantly inhibited the abdominal writhing induced by acetic acid and the licking times in formalin test at both phases.

Conclusions:
These findings suggest that the plant may be a potential source for the development of a new antinociceptive drug and slightly suitable for diarrhea, as it exhibited lower activity. Our observations resemble previously published data on P. imbricatum leaves.
Cutaneous temperature sensitivity alteration in subjects with chronic stroke sequelae – pharmacological perspectives
Authors: Santos Artur Cesar Aquino , Alfieri Fábio Marcon , Battistella Linamara Rizzo 
Published: August 2017

Abstract

Background:
Stroke can result in body temperature sensitivity changes. This study analyzed abnormal temperature perception of patients with stroke and the use of vasoactive drugs.

Methods:
A cross-sectional retrospective study was carried out consisting of 100 patients (55.6±12.9 years old), from both genres, with either hemorrhagic or ischemic stroke, with unilateral hemiplegia or hemiparesis. Subjects had axillary temperature and different temperature sensitivities of the limbs measured using a visual analog scale (VAS). Information on the use of medical drugs was collected in clinical records.

Results:
In total, 64 patients reported body temperature alterations, and 62 patients stated they feel cold in the affected side. They reported 6.12±2.44 cm alteration for the upper limb and 6.72±2.44 cm for the lower limb in the VAS. Some 86 different drugs were identified in the 85 medical records available. There was a prevalence of a group of drugs formed by the β-blockers, dopamine agonists, dopamine reuptake Inhibitors, tricyclic antidepressants (TCAs) and another group formed by the selective serotonin reuptake inhibitors.

Conclusions:
Most of the subjects reported a sensation of cold in the affected limbs. The β-blockers, dopamine agonists, dopamine reuptake inhibitors, and TCAs seem to be related to this sensation, however, due to the number of uncontrolled variables that may be related to these drugs and the possible role of nitric oxide, it was not possible to establish precise relations regarding the use of a specific group of drugs and the cold sensation in the affected limbs, as reported by the patients.
Magneto-elastic SV-wave at the interface of pre-stressed surface with voids under rotation
Authors: Kakar Rajneesh , Kakar Shikha 
Published: August 2017

AbstractThe aim of this paper is to study the behaviour of reflection of SV- wave at a free surface under the effects of magnetic field, initial stress, rotation and voids. When a SV- wave is incident on the free surface of an elastic half space, two damped P-waves and a SV-wave is reflected. Among of these waves, P-waves are only affected by magnetic field and rotation whereas SV-wave is influenced by rotation, initial stress and magnetic field. Numerical computations are performed for the developed amplitude ratios of P-, SV- and magneto-elastic waves. This study would be useful for magneto-elastic acoustic device field and further study about nature of seismic waves.

AbstractBackground:Tandem mass spectrometry (TMS)-based newborn screening has been proven successful as one of the public healthcare programs, although the practicability has not yet been specifically addressed.Methods:Sixty residual dried blood spot (DBS) specimens from confirmation/diagnosis-insufficient cases discovered by TMS screening were analyzed by targeted next generation sequencing (TNGS) assay.Results:In total, 26, 11, 9, and 14 cases were diagnosed as positive, high risk, low risk, and negative, respectively.Conclusions:Applying the DBS-based TNGS assay for the accurate and rapid diagnosis of inborn errors of metabolism (IEMs) is feasible, competent, and advantageous, enabling a simplified TMS screening-based, TNGS assay-integrated newborn screening scheme highlighting an efficient, executable, and one-step screening-to-diagnosis workflow.
Exciton-plasmon coupling interactions: from principle to applications
Authors: Cao En , Lin Weihua , Sun Mengtao , Liang Wenjie , Song Yuzhi 
Published: August 2017

Abstract
The interaction of exciton-plasmon coupling and the conversion of exciton-plasmon-photon have been widely investigated experimentally and theoretically. In this review, we introduce the exciton-plasmon interaction from basic principle to applications. There are two kinds of exciton-plasmon coupling, which demonstrate different optical properties. The strong exciton-plasmon coupling results in two new mixed states of light and matter separated energetically by a Rabi splitting that exhibits a characteristic anticrossing behavior of the exciton-LSP energy tuning. Compared to strong coupling, such as surface-enhanced Raman scattering, surface plasmon (SP)-enhanced absorption, enhanced fluorescence, or fluorescence quenching, there is no perturbation between wave functions; the interaction here is called the weak coupling. SP resonance (SPR) arises from the collective oscillation induced by the electromagnetic field of light and can be used for investigating the interaction between light and matter beyond the diffraction limit. The study on the interaction between SPR and exaction has drawn wide attention since its discovery not only due to its contribution in deepening and broadening the understanding of SPR but also its contribution to its application in light-emitting diodes, solar cells, low threshold laser, biomedical detection, quantum information processing, and so on.

Published: August 2017

Abstract
The equiatomic rare earth iridium indides REIrIn (RE=La, Pr, Nd, Er–Yb) were synthesized by reaction of the elements in induction or muffle furnaces and were characterized through X-ray powder patterns. The structures of LaIr0.86In1.14, PrIr0.89In1.11, NdIr0.94In1.06, ErIrIn (all ZrNiAl type, P6̅2m), and YbIrIn (TiNiSi type, Pnma) were refined from single crystal X-ray diffractometer data. Refinements of the occupancy parameters revealed small degrees of solid solutions with indium substitution on the iridium sites. Chemical bonding analyses and electronic structure calculations indicate the dominance of metallic bonding in addition to partial ionic interactions between the cations and polyanions, as well as covalent contributions between the indium and iridium atoms.

Published: August 2017

Background and Purpose:
Understanding fall risk factors in people with mild cognitive impairment (MCI) and Alzheimer disease (AD) can help to establish specific plans for prevention of falls. The purpose of this study was to identify fall risk factors in older adults with MCI and mild AD.

Methods:
A prospective study was conducted with community-dwelling older adults (40 MCI; 38 mild AD). The assessments consisted of sociodemographic and health variables, caloric expenditure, functional status, functional mobility (10-m walk test, dual-task test, and transition Timed Up and Go phases), cognitive domains, and depressive symptoms. Falls were recorded for 6 months by a falls calendar and monthly telephone calls.

Results:
Falls were reported in 52.6% and 51.4% of people with MCI and mild AD, respectively. Among people with MCI, lower functional status, higher time spent on walk and dual task tests, and higher depressive symptom scores were associated with falls. Higher time spent on the dual-task test was independently associated with falls. Among people with mild AD, falls were associated with lower time spent on the walk test and turn-to-sit phase, and a higher visuospatial domain score. Lower time spent on the turn-to-sit phase was identified as an independent predictor of falls.

Conclusions:
Careful attention should be given to dual-task and turn-to-sit activities when detecting risk of falls among older people with MCI and mild AD.

Abstract
Pérez-Castilla, A, McMahon, JJ, Comfort, P, and García-Ramos, A. Assessment of loaded squat jump height with a free-weight barbell and Smith machine: comparison of the takeoff velocity and flight time procedures. J Strength Cond Res 34(3): 671–677, 2020—The aims of this study were to compare the reliability and magnitude of jump height between the 2 standard procedures of analyzing force platform data to estimate jump height (takeoff velocity [TOV] and flight time [FT]) in the loaded squat jump (SJ) exercise performed with a free-weight barbell and in a Smith machine. Twenty-three collegiate men (age, 23.1 ± 3.2 years; body mass, 74.7 ± 7.3 kg; height, 177.1 ± 7.0 cm) were tested twice for each SJ type (free-weight barbell and Smith machine) with 17-, 30-, 45-, 60-, and 75-kg loads. No substantial differences in reliability were observed between the TOV (coefficient of variation [CV], 9.88%; intraclass correlation coefficient [ICC], 0.82) and FT (CV, 8.68%; ICC, 0.88) procedures (CV ratio, 1.14), whereas the Smith SJ (CV, 7.74%; ICC, 0.87) revealed a higher reliability than the free-weight SJ (CV, 9.88%; ICC, 0.81; CV ratio, 1.28). The TOV procedure provided higher magnitudes of jump height than the FT procedure for the loaded Smith machine SJ (systematic bias, 2.64 cm; p ≤ 0.05), whereas no significant differences between the TOV and FT procedures were observed in the free-weight SJ exercise (systematic bias, 0.26 cm; p > 0.05). Heteroscedasticity of the errors was observed for the Smith machine SJ (r
2 = 0.177) with increasing differences in favor of the TOV procedure for the trials with lower jump height (i.e., higher external loads). Based on these results, the use of a Smith machine in conjunction with the FT more accurately determine jump height during the loaded SJ.
