Coaches’ Bases of Power and Coaching Effectiveness in Team Sports
Authors: Rylander Pär
Published: May 2016

The purpose of the current study was to investigate the relationship between team sport coaches’ power and coaching effectiveness using French and Raven’s (1959) taxonomy of power bases as a theoretical framework. Coaching effectiveness (CE) was conceptualized as an umbrella concept and four different CE outcomes were used; athletes’ satisfaction with the coach, coaches’ general influence, adaptive training behaviours, and collective efficacy. Hypotheses were made on the specific relationships between the individual power bases and the effectiveness criteria. The total sample consisted of 820 athletes (47% females), representing 56 elite and nonelite teams from three team sports (soccer, floorball, and team handball). Data were analysed separately for adults and youths. Structural equations modelling showed that 30% (in the youth sample) and 55% (in the adult sample) of the proposed hypotheses was supported. Overall, coaches’ bases of power were strongly associated with coaching effectiveness, explaining between 13% and 59% of variance in the effectiveness outcomes used. Expert power was consistently positively related to coaching effectiveness; reward and coercive power had mixed relationships (positively, negatively, unrelated) as had legitimate power (negatively, unrelated) and reward power (positively, unrelated). The results are discussed in relation to coaching effectiveness, limitations, practical implications and future research.
The Anatomy of a Successful Olympic Coach: Actor, Agent, and Author
Authors: Mallett Clifford J. , Coulter Tristan J.
Published: May 2016

Little in-depth knowledge is known about the person behind successful coaching. Therefore, the current study was designed to comprehensively examine the personality of a successful Olympic coach. Using McAdams’ whole-person framework, we sought to elicit a coherent description of this coach’s personality by integrating data drawn from three layers of personality: (i) dispositional traits, (ii) personal strivings, and (iii) narrative identity. The findings suggest that, compared with the norm, the participant coach is emotionally stable, agreeable, conscientious, and open to new experiences. His achievement and power strivings shape his motivational agenda as a coach. His narrative identity identifies many redemptive sequences that speak of a coach who is seeking to redeem his failures as an athlete, to feel special, and who invests himself wholeheartedly into developing others to help fulfill their potential. Overall, the study, incorporating McAdams’ personality framework, provided a deep understanding of the person as a coach. We were able to garner insights about how this individual typically behaves, what guides and structures his coaching priorities, and how he has made sense of his life experiences that are fundamental to his investment in coaching and winning. Tentative implications for coaches and coach developers are presented.
Profiling the Canadian High School Teacher-Coach: A National Survey
Authors: Camiré Martin , Rocchi Meredith , Kendellen Kelsey
Published: May 2016

Each academic year, a large number of teachers voluntarily assume coaching positions in Canadian high schools and thus undertake the dual role of teacher-coach. To date, much of the scholarship on teacher-coaches has been conducted with small samples of participants and as such, the conclusions that can be drawn about the status of the Canadian teacher-coach are limited. The purpose of the current study was to profile the Canadian high school teacher-coach using a national sample. A total of 3062 teacher-coaches (males = 2046, 67%) emanating from all Canadian provinces and territories completed a questionnaire examining personal background and work conditions. Results indicated that aspects of teacher-coaches’ personal background significantly influenced the benefits and challenges they perceived from coaching as well as the recommendations they suggested to improve their coaching experience. The recommendations put forth by the teacher-coaches to improve their work conditions must be earnestly considered by school administrators to ensure the long-term viability of the Canadian high school sport system, which is largely sustained by dedicated volunteers.
Is There a Need for Coaches to Be More Gender Responsive? A Review of the Evidence
Authors: Norman Leanne
Published: May 2016

The purpose of this paper is to explore current research evidence to understand whether and how gender influences the coach-athlete relationship. Considering the importance of coach-athlete relationships, the field still remains under researched and the influences on this relationship require greater examination. Coach-athlete exchanges are shaped by assumptions and ideas about coaching and teaching relationships. Interactions are complex because sport makes a number of (at times competing) demands on participants. Varying individual characteristics increase this complexity. Yet within this multifaceted context, gender relations appear constant and problematic, particularly with respect to coaching. Evidence suggests that while male and female athletes share many similarities in what they want and prefer in terms of their coaching needs and expectations, there are specific nuances and differences that must be understood to facilitate an effective relationship. Furthermore, the evidence also suggests that male coaches, unwittingly, play a role in the perpetuation of the stereotype of women as the less able, less competitive and frailer athlete. These findings evidence the need to include a greater focus on gender-responsive coaching. The paper also highlights different coaching styles that may facilitate working with male and female athletes and emphasises the need for coaches to become relational experts to empower their athletes.

Authors: Kishan Rama , Saibaba Balaji , Kumar Vishal , Aggarwal Sameer
Published: May 2016

Conjoint bicondylar coronal plane fracture is a rare orthopaedic injury, associated with high-velocity trauma. The proposed mechanism is axially directed shear forces in a flexed knee. To the best of our literature search, only 2 cases of conjoint bicondylar coronal fracture have been published in English literature—1 each in adult and paediatric age group. Conjoint bicondylar coronal plane fracture with incarcerated patella has not yet been reported and hence this is the first report of its kind. We report on the clinical presentation, management and outcome of such a complex injury, along with a comprehensive, up-to-date literature review. Prompt open reduction and internal fixation coupled with early knee mobilisation is the key to achieve good functional outcome.
Emergent pacemaker placement in a patient with Lyme carditis-induced complete heart block and ventricular asystole
Authors: Brownstein Adam J , Gautam Samir , Bhatt Paras , Nanna Michael
Published: May 2016

We report a case of a 31-year-old man who presented to the emergency department after four episodes of syncope within a 24 h time span. He was found to have symptomatic complete heart block associated with episodes of ventricular asystole lasting 5–6 s. He underwent emergent permanent pacemaker insertion during which he was found to have no underlying rhythm. He was later found to have positive serologies for Lyme disease despite no known exposure to ticks and neither signs nor symptoms of the disease. The pacemaker was ultimately removed due to resolution of his heart block with antibiotic therapy.
Development of a Multi-period Output Model for Considering Time Lag Effect
Authors: Zhang Yanshuang , Jeong Byung Ho
Published: May 2016

Existing data envelopment analysis (DEA) models have focused on evaluating the relative efficiency of decision making units (DMUs) based on multiple input and output factors for the same period. However, a certain kind of lead time is sometimes required to produce outputs using inputs in an organization. R&D evaluation is a typical area with this kind of time lag. Thus, the purpose of this paper is to develop a new DEA model to deal with time lag effect in performance evaluation. The suggested model defines the efficiency measure of a DMU by using outputs of multiple periods in different view with existing multi-period input (MpI) model. Three varieties of the suggested model are presented by adding three kinds of constraints based on the different types of time lag effect. A case example using a real data set is given to demonstrate the usage or implications of the suggested models. In the experimental section, the results of the suggested models are compared with the results of CCR and the MpI model using the data set of the 21st Century Frontier R&D program which is a long-term national R&D program of Korea.

Authors: Jiang Jianfei , Mao Zhigang , Sheng Weiguang , Wang Qin , He Weifeng
Published: May 2016

On-chip global interconnects are becoming speed and power bottlenecks in state-of-the-art chips. Low-swing signaling is used to improve delay performance and reduce power consumption. This paper first performs a delay analysis for different low-swing circuits based on the Asymptotic Waveform Evaluation (AWE). In addition, new delay metrics are presented and analyzed. The new delay metrics demonstrate that optimal designs can be obtained in low-swing signaling. To verify our analysis, a simulation environment is established. The simulation results indicate that the optimal designs can increase the 3[Formula: see text]dB bandwidth of a wire by more than 40% in resistively driven or capacitively driven 10[Formula: see text]mm global links. Thus, these optimal design methods can effectively improve the bandwidth of global wires.
Error-disturbance uncertainty relations in neutron spin measurements
Authors: Sponar Stephan
Published: May 2016

Heisenberg’s uncertainty principle in a formulation of uncertainties, intrinsic to any quantum system, is rigorously proven and demonstrated in various quantum systems. Nevertheless, Heisenberg’s original formulation of the uncertainty principle was given in terms of a reciprocal relation between the error of a position measurement and the thereby induced disturbance on a subsequent momentum measurement. However, a naive generalization of a Heisenberg-type error-disturbance relation for arbitrary observables is not valid. An alternative universally valid relation was derived by Ozawa in 2003. Though universally valid, Ozawa’s relation is not optimal. Recently, Branciard has derived a tight error-disturbance uncertainty relation (EDUR), describing the optimal trade-off between error and disturbance under certain conditions. Here, we report a neutron-optical experiment that records the error of a spin-component measurement, as well as the disturbance caused on another spin-component to test EDURs. We demonstrate that Heisenberg’s original EDUR is violated, and Ozawa’s and Branciard’s EDURs are valid in a wide range of experimental parameters, as well as the tightness of Branciard’s relation.

TRIFL
Authors: That Dai Hai Ton , Popa Iulian Sandu , Zeitouni Karine
Published: May 2016

Due to several important features, such as high performance, low power consumption, and shock resistance, NAND flash has become a very popular stable storage medium for embedded mobile devices, personal computers, and even enterprise servers. However, the peculiar characteristics of flash memory require redesigning the existing data storage and indexing techniques that were devised for magnetic hard disks.

In this article, we propose TRIFL, an efficient and generic TRajectory Index for FLash. TRIFL is designed around the key requirements of trajectory indexing and flash storage. TRIFL is generic in the sense that it is efficient for both simple flash storage devices such as SD cards and more powerful devices such as solid state drives. In addition, TRIFL is supplied with an online self-tuning algorithm that allows adapting the index structure to the workload and the technical specifications of the flash storage device to maximize the index performance. Moreover, TRIFL achieves good performance with relatively low memory requirements, which makes the index appropriate for many application scenarios. The experimental evaluation shows that TRIFL outperforms the representative indexing methods on magnetic disks and flash disks.
Privacy-Aware Dynamic Ride Sharing
Authors: Goel Preeti , Kulik Lars , Ramamohanarao Kotagiri
Published: May 2016

Dynamic ride sharing is a service that enables shared vehicle rides in real time and on short notice. It can be an effective solution to counter the problem of increasing traffic jams at peak hours in cities. The growing use and popularity of smart phones and GPS-enabled devices provides us with tools required to efficiently implement ride sharing and significantly enhance carpooling. However, privacy and safety concerns are the main obstacles faced when encouraging people to use such a service. In this work, we present “Match Maker,” a negotiation-based model that hides exact location information data for system participants while implementing privacy preserving ride sharing. We use the concept of imprecision (not being precise about location of the user out of set of
n
locations) and follow the idea of obfuscation, which equates a higher degree of imprecision with a higher degree of privacy. We identify two attack types that could circumvent privacy preserving ride sharing. We compare the Match Maker model with the standard central trusted server model collecting precise location data, which we term eBay model. We provide the first comprehensive approach that integrates privacy, safety and trust in a single model. We present a recursive ellipse-based algorithm to compute an optimal driver path as well as three negotiation strategies for drivers and passengers. We conduct extensive experiments on real road networks and compare the strategies for privacy and effectiveness of ride sharing in terms of traffic load and vehicle km reduction. We show that ride sharing saves between 9% and 21% (on average 12%) of vehicle km if drivers are only prepared to accept slight detours of their usual trips. In the city of Melbourne, with 11.6 million trips a weekday and an average trip length of 10.2 km, this would save 14.2 million km per weekday.
PREFiguRE
Authors: Yan Feng , Mountrouidou Xenia , Riska Alma , Smirni Evgenia
Published: May 2016

Low disk drive utilization suggests that placing the drive into a power saving mode during idle times may decrease power consumption. We present PREFiguRE, a robust framework that aims at harvesting future idle intervals for power savings while meeting strict quality constraints: first, it contains potential delays in serving IO requests that occur during power savings since the time to bring up the disk is not negligible, and second, it ensures that the power saving mechanism is triggered a few times only, such that the disk wear-out due to powering up and down does not compromise the disk’s lifetime. PREFiguRE is based on an analytic methodology that uses the histogram of idle times to determine schedules for power saving modes as a function of the preceding constraints. PREFiguRE facilitates analysis for the evaluation of the trade-offs between power savings and quality targets for the current workload. Extensive experimentation on a set of enterprise storage traces illustrates PREFiguRE’s effectiveness to consistently achieve high power savings without undermining disk reliability and performance.
A Unified Approach to the Performance Analysis of Caching Systems
Authors: Garetto Michele , Leonardi Emilio , Martina Valentina
Published: May 2016

We propose a unified methodology to analyze the performance of caches (both isolated and interconnected), by extending and generalizing a decoupling technique originally known as Che’s approximation, which provides very accurate results at low computational cost. We consider several caching policies (including a very attractive one, called
k
-LRU), taking into account the effects of temporal locality. In the case of interconnected caches, our approach allows us to do better than the Poisson approximation commonly adopted in prior work. Our results, validated against simulations and trace-driven experiments, provide interesting insights into the performance of caching systems.

Published: May 2016

Fêmeas e machos castrados, em fase de crescimento e terminação, foram submetidos a diferentes níveis de proteína em dietas com e sem suplementação de aminoácidos industriais. Foram utilizados 72 animais, 36 de cada sexo, com pesos médios iniciais de 30,73 e 30,38 kg (fase de crescimento) e 61,08 e 57,31 kg (fase de terminação), respectivamente. Adotou-se o delineamento blocos ao acaso com três tratamentos, seis repetições e dois animais por unidade experimental. Os tratamentos corresponderam a dietas com os níveis de protéicos: 19,40; 16,80 e 14,90% na fase crescimento e 17,8; 15,40 e 13,60% na fase terminação. Na fase de crescimento, as dietas com 16,80 e 14,90% de proteína bruta são as indicadas para fêmeas e machos castrados, respectivamente. Na fase de terminação, a dieta com 17,80% de proteína bruta, sem aminoácidos suplementares, seria indicada para fêmeas e machos castrados da genética estudada se o custo do farelo de soja for viável para assegurar a concentração de lisina digestível estuda e o retorno econômico. Preços do farelo de soja, dos aminoácidos industriais e do suíno determinarão a viabilidade da estratégia alimentar nessas fases do desenvolvimento. Outro fator na adoção dos níveis protéicos aplicados aos machos castrados na fase de terminação é o preço do suíno pago pelo frigorífico, no caso da classificação de carcaça, uma vez que a redução dietética da proteína implica em maior acúmulo de gordura corporal.
Contributions to an anthropology of work: On the role of psycho-technicians in the management of freedom within the Dutch police
Authors: Mutsaers Paul
Published: May 2016

Organizational life has taken on a psychological hue now that psychological expertise has become an ever more important factor in matters such as selection, job evaluation, work design, job enrichment and the like. This phenomenon is not new, but has recently received new critical commentary in various disciplines. This article contributes to an anthropology of the ‘cognitive turn’ in diversity management (DM) within the Dutch police on the basis of an ethnographic study between 2008 and 2013. In particular, it seeks to enhance our understanding of the role of ‘psycho-technicians’ in this matter and looks at the domaining effect of their productions: What happens when their (discursive) management techniques leave the context of production and become operational in different contexts of usage? The article builds upon various concepts that are common in the field of linguistic anthropology (e.g. entextualization, interdiscursivity, intertextual asymmetry, pretextuality and strategically deployable shifters) to answer this question.

Background

Long non-coding RNAs (lncRNAs) have emerged as biomarkers and important regulators of tumor development and progression. PANDAR (promoter of CDKN1A antisense DNA damage activated RNA) is a novel long non-coding RNA that acts as a potential biomarker and involves in development of multiple cancers. However, the clinical significance and molecular mechanism of PANDAR in bladder cancer is still unknown. In this study, we aimed to figure out the role of PANDAR in bladder cancer.

Methods

The relative expression level of lncRNA PANDAR was determined by Real-Time qPCR in a total of 55 patients with urothelial bladder cancer and in different bladder cancer cell lines. We inhibited PANDAR expression by transfecting PANDAR specific siRNA and enhanced PANDAR expression by transfecting a PANDAR expression vector (pcDNA3.1-PANDAR). Cell proliferation was determined by using both CCK-8 assay and Edu assay. Cell apoptosis was determined by using ELISA assay, Hoechst 33342 staining and Flow cytometry. Cell migration was determined by using transwell assay. All experimental data from three independent experiments were analyzed by χ2 test or Student’s t-test and results were expressed as mean ± standard deviation.

Results

We found that PANDAR was significantly up-regulated in bladder cancer tissues compared with paired-adjacent nontumorous tissues in a cohort of 55 bladder cancer patients. Moreover, increased PANDAR expression was positively correlated with higher histological grade (P < 0.05) and advanced TNM stage (P < 0.05). Further experiments demonstrated that inhibited cell proliferation/migration and induced apoptosis by silencing PANDAR were also observed in bladder cancer cells. Furthermore, over expression of PANDAR in bladder cancer cells promoted the proliferation/migration and suppressed apoptosis.

Conclusions

These findings demonstrate that PANDAR plays oncogenic roles in bladder cancer and PANDAR may serve as a potential prognostic biomarker and therapeutic target of bladder cancer.
Damped multichannel singular spectrum analysis for 3D random noise attenuation
Authors: Huang Weilin , Wang Runqiu , Chen Yangkang , Li Huijian , Gan Shuwei
Published: May 2016

Multichannel singular spectrum analysis (MSSA) is an effective algorithm for random noise attenuation in seismic data, which decomposes the vector space of the Hankel matrix of the noisy signal into a signal subspace and a noise subspace by truncated singular value decomposition (TSVD). However, this signal subspace actually still contains residual noise. We have derived a new formula of low-rank reduction, which is more powerful in distinguishing between signal and noise compared with the traditional TSVD. By introducing a damping factor into traditional MSSA to dampen the singular values, we have developed a new algorithm for random noise attenuation. We have named our modified MSSA as damped MSSA. The denoising performance is controlled by the damping factor, and our approach reverts to the traditional MSSA approach when the damping factor is sufficiently large. Application of the damped MSSA algorithm on synthetic and field seismic data demonstrates superior performance compared with the conventional MSSA algorithm.
Accelerating extended least-squares migration with weighted conjugate gradient iteration
Authors: Hou Jie , Symes William W.
Published: May 2016

Least-squares migration (LSM) iteratively achieves a mean-square best fit to seismic reflection data, provided that a kinematically accurate velocity model is available. The subsurface offset extension adds extra degrees of freedom to the model, thereby allowing LSM to fit the data even in the event of significant velocity error. This type of extension also implies additional computational expense per iteration from crosscorrelating source and receiver wavefields over the subsurface offset, and therefore places a premium on rapid convergence. We have accelerated the convergence of extended least-squares migration by combining the conjugate gradient algorithm with weighted norms in range (data) and domain (model) spaces that render the extended Born modeling operator approximately unitary. We have developed numerical examples that demonstrate that the proposed algorithm dramatically reduces the number of iterations required to achieve a given level of fit or gradient reduction compared with conjugate gradient iteration with Euclidean (unweighted) norms.
Crosshole seismic tomography with cross-firing geometry
Authors: Rao Ying , Wang Yanghua , Chen Shumin , Wang Jianmin
Published: May 2016

We have developed a case study of crosshole seismic tomography with a cross-firing geometry in which seismic sources were placed in two vertical boreholes alternatingly and receiver arrays were placed in another vertical borehole. There are two crosshole seismic data sets in a conventional sense. These two data sets are used jointly in seismic tomography. Because the local sediment is dominated by periodic, flat, thin layers, there is seismic anisotropy with different velocities in the vertical and horizontal directions. The vertical transverse isotropy anisotropic effect is taken into account in inversion processing, which consists of three stages in sequence. First, isotropic traveltime tomography is used for estimating the maximum horizontal velocity. Then, anisotropic traveltime tomography is used to invert for the anisotropic parameter, which is the normalized difference between the maximum horizontal velocity and the maximum vertical velocity. Finally, anisotropic waveform tomography is implemented to refine the maximum horizontal velocity. The cross-firing acquisition geometry significantly improves the ray coverage and results in a relatively even distribution of the ray density in the study area between two boreholes. Consequently, joint inversion of two crosshole seismic data sets improves the resolution and increases the reliability of the velocity model reconstructed by tomography.
Zooming In on Choice: How Do Consumers Search for Cameras Online?
Authors: Bronnenberg Bart J. , Kim Jun B. , Mela Carl F.
Published: May 2016

We describe online consumers’ search behavior for differentiated durable goods using a data set that captures a detailed level of consumer search and attribute information for digital cameras. Consumers search extensively, engaging in 14 searches on average prior to purchase. Individual level search is confined to a small part of the attribute space. Early search is highly predictive of the characteristics of the camera eventually purchased. Search paths through the attribute space are state dependent and display “lock-in” as the search unfolds. Finally, the first-time discovery of the chosen alternative usually takes place toward the end of the search sequence. We discuss these and other findings in the context of optimal search strategies and discuss the prospects for consumer learning during search.

Boundary layer atmospheric ozone depletion events (ODEs) are commonly observed across polar sea ice regions following polar sunrise. During March-April 2005 in Alaska, the coastal site of Barrow and inland site of Atqasuk experienced ODEs (O3< 10 nmol mol-1) concurrently for 31% of the observations, consistent with large spatial scale ozone depletion. However, 7% of the time ODEs were exclusively observed inland at Atqasuk. This phenomenon also occurred during one of nine flights during the BRomine, Ozone, and Mercury EXperiment (BROMEX), when atmospheric vertical profiles at both sites showed near-surface ozone depletion only at Atqasuk on 28 March 2012. Concurrent in-flight BrO measurements made using nadir scanning differential optical absorption spectroscopy (DOAS) showed the differences in ozone vertical profiles at these two sites could not be attributed to differences in locally occurring halogen chemistry. During both studies, backward air mass trajectories showed that the Barrow air masses observed had interacted with open sea ice leads, causing increased vertical mixing and recovery of ozone at Barrow and not Atqasuk, where the air masses only interacted with tundra and consolidated sea ice. These observations suggest that, while it is typical for coastal and inland sites to have similar ozone conditions, open leads may cause heterogeneity in the chemical composition of the springtime Arctic boundary layer over coastal and inland areas adjacent to sea ice regions.

different combinations of process parameters: pulse
frequency, pulse energy and laser beam scanning speed.
The morphological characterization of ablated surfaces
has been performed using scanning electron microscopy
(SEM) technique.

The results show limited possibility of ns pulse fibre laser
application to generate different surface structures for tribological
modification of metallic materials. These structures
were obtained by varying the processing conditions
between surface ablation, to surface remelting. In all cases
the areas of molten material and re-cast layers were observed

Authors: Zhao Xiaoli , Luo Guowei , Bai Chunqing , Peng Hailong , Xiong Hua
Published: May 2016

In this research, thermosensitive liposomes (t-L) containing juglone were prepared with 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) and cholesterol by aether injection method. Morphological characteristics, encapsulation efficiency (EE), particle size, zeta potential, in vitro release, and cell viability of t-L were investigated and compared with those of conventional liposomes (c-L). Results indicated that t-L are multilamellar vesicles with lower negative charge, larger particle diameter, and higher EE than c-L. Moreover, in vitro juglone release from t-L was temperature dependent. Up to 60 % of the loaded juglone was released from t-L in 20 min when environmental temperature was increased from 37 °C to 42 °C; by contrast, >60 % of the drug remained inside for 24 h at 37 °C. Furthermore, MTT assay results revealed that t-L significantly increased the inhibitory effect on HepG2 cell growth and proliferation when these cells were exposed to hyperthermia; therefore, t-L could be applied for targeted therapy.

A variationist account of voice onset time (VOT) among bilingual West Indians in Panama
Authors: Lamy Delano S.
Published: May 2016

The present study is concerned with language contact between Creole English and Spanish spoken by bilingual West Indians living in Panama City, Panama. The goal is to examine the speech patterns of monolinguals of Creole English and Spanish and Creole English-Spanish bilinguals by employing the comparative variationist method. A series of statistical comparisons of the factors contributing to voice onset time (VOT) of the voiceless coronal plosive /t/ in four varieties were carried out to address phonetic permeability due to contact. These comparisons reveal evidence of different types of contact-induced outcomes among bilinguals. When speaking Spanish, convergence, which is the result of direct transfer from Creole English, is apparent in terms of rate of speech. When speaking Creole English, there is also evidence of convergence, particularly in the preceding segment variable. Furthermore, the comparisons reveal processes of indirect transfer from Spanish, such as simplification in terms of following vowel height, and the creation of alternations in terms of phone position and syllable stress. These contact-induced changes are interpreted as evidence that bilingual West Indians are resisting influence from a more dominant Mestizo culture, and are creating West Indian norms. It is proposed that this community is in the initial stages of developing new emerging varieties.

Published: May 2016

Simulator training in interventional cardiology is becoming a central part of early career acquisition of technical and non-technical skills. Its use is now mandated by national training organisations. Haptic simulators, part-task trainers, immersive environments and simulated patients can provide benchmarked, reproducible and safe opportunities for trainees to develop without exposing patients to the learning curve. However, whilst enthusiasm persists and trainee-centred evidence has been encouraging, simulation does not yet have a clear link to improved clinical outcomes. In this article we describe the range of simulation options, review the evidence for their efficacy in training and discuss the delivery of training in technical skills as well as human factor training and crisis resource management. We also review the future direction and barriers to the progression of simulation training.

Ministry to US Catholic LGBTQ Youth: A Call for More Openness and Affirmation
Authors: Canales Arthur David
Published: May 2016

This article evaluates the current Catholic youth ministry practice to, with, and for Catholic LGBTQ youth. The methodology utilized is both descriptive and prescriptive, and calls into question the lack of ministerial presence afforded to Catholic LGBTQ youth. The essay briefly examines the official ecclesiastical documents on homosexuality and their relevance for LGBTQ youth. Next it assesses the major US ecclesial youth ministry document, Renewing the Vision, and calls for its renewal and revision.  In particular the article offers concrete recommendations for the two areas of Catholic youth ministry—advocacy and pastoral care—that would have the most positive impact for LGBTQ youth and Catholic youth ministry. Finally, the article calls for the US Catholic bishops, youth ministers, and parents to be more open and affirming with LGBTQ youth and provides some practical suggestions.

Welcoming the Stranger: Anatheism and L'Arche
Authors: Little Brent
Published: May 2016

In his book Anatheism, Richard Kearney argues for God to be imagined as a stranger and a guest, a God who comes unexpectedly into mundane reality. As a potential host, the human person may freely say yes in hospitality or no in hostility to this divine stranger, a hospitality or hostility practised in encounters with the everyday strangers of life, such as marginalized populations. As an exemplar, Kearney offers Jean Vanier's vision for L'Arche, a global network of communities that live in solidarity with the developmentally disabled. But Kearney provides only a start for a theological dialogue with L'Arche's experience. In order to further refine this conversation between Kearney and L'Arche, I consider questions about the limits of hospitality in the context of L'Arche. What are, for example, necessary boundaries between guest and host? When does uncritical hospitality become problematic? After a discussion of Kearney's anatheism and the writings of Vanier, Henri Nouwen, and others, I argue for the necessity of judiciously drawn boundaries so as to promote a healthy relationship between the disabled person and the assistant, a relationship that hopefully has become one of friendship. This article, then, confronts the task of discerning the limits to Kearney's paradigm, and L'Arche's practice, of hospitality.
Kierkegaard's Relation to Catholic Theology and the Broader Christian World
Authors: Evans C. Stephen
Published: May 2016

This article responds to articles by Joshua Furnal and Lee Barrett on the relation of Kierkegaard's thought to Catholic theology. I express appreciation for Furnal's claim that Kierkegaard had a deep impact on Vatican ii and suggest this was made possible by Kierkegaard's commitment to the early Christian fathers, which makes him a “ressourcement” theologian. Barrett's view of Kierkegaard's account of the relation between nature and grace is also applauded, and I suggest another way Kierkegaard can be seen as reconciling Protestant and Catholic thought on this issue. I conclude by putting this discussion into the broader context of Kierkegaard's positive reception by many different strands of Christianity, suggesting that this is made possible by Kierkegaard's commitment to something like “mere Christianity” in C.S. Lewis's sense, along with his fervent defence of passion and subjectivity as the elements that give life to religious faith.
Literature and Law: Consensus and the Art of Disagreement
Authors: Kertzer Jon
Published: May 2016

Literary and legal judgments require, formulate, and defend, but also retain an urge to disrupt, a consensus of like-minded people. This essay studies the aesthetic of taste in literature and the jury system in law to show how consensus works, and at what cost. Using Pierre Bourdieu's model of social “fields” competing for authority, it argues that consensus must be won within a dissensus that it can never quite quell. Concord emerges from discord, which remains unruly. This dynamic energizes theories of taste (Burke, Hume, Scarry), which derive social and moral relevance from the sensory immediacy of art, and the jury system, which theatrically forges agreement out of judicial dispute. Jane Austen provides examples of irony in the service of critical taste; the O.J. Simpson criminal trial illustrates the tribulations of reaching a unanimous verdict, which it displays to a disputatious public.
Robots and the “End of Work” in Archibald Lampman's “City of the End of Things”
Authors: Stacey Robert David
Published: May 2016

This essay examines the representation of work in Archibald Lampman's “The City of the End of Things” in order to challenge received ideas about Lampman's socialist politics. In particular, the essay argues that the poem's negative treatment of automation suggests a disjuncture between his beliefs and those of the Fabian Society, with which he has repeatedly been associated. Arguing that Lampman's views on labour and production are more consonant with William Morris's economic theory, the essay counters readings of the poem as a critique of alienated labour, suggesting that Lampman's primary concern is actually the elimination of work via the application of technology to the production process.

Renal artery injury during lateral transpsoas interbody fusion: case report
Authors: Blizzard Daniel J. , Gallizzi Michael A. , Isaacs Robert E. , Brown Christopher R.
Published: May 2016

Lateral interbody fusion (LIF) via the retroperitoneal transpsoas approach is an increasingly popular, minimally invasive technique for interbody fusion in the thoracolumbar spine that avoids many of the complications of traditional anterior and transforaminal approaches. Renal vascular injury has been cited as a potential risk in LIF, but little has been documented in the literature regarding the etiology of this injury. The authors discuss a case of an intraoperative complication of renal artery injury during LIF. A 42-year-old woman underwent staged T12–L5 LIF in the left lateral decubitus position, and L5–S1 anterior lumbar interbody fusion, followed 3 days later by T12–S1 posterior instrumentation for idiopathic scoliosis with radiculopathy refractory to conservative management. After placement of the T12–L1 cage, the retractor was released and significant bleeding was encountered during its removal. Immediate consultation with the vascular team was obtained, and hemostasis was achieved with vascular clips. The patient was stabilized, and the remainder of the procedure was performed without complication. On postoperative CT imaging, the patient was found to have a supernumerary left renal artery with complete occlusion of the superior left renal artery, causing infarction of approximately 75% of the kidney. There was no increase in creatinine level immediately postoperatively or at the 3-month follow-up. Renal visceral and vascular injuries are known risks with LIF, with potentially devastating consequences. The retroperitoneal transpsoas approach for LIF in the superior lumbar spine requires a thorough knowledge of renal visceral and vascular anatomy. Supernumerary renal arteries occur in 25%–40% of the population and occur most frequently on the left and superior to the usual renal artery trunk. These arteries can vary in number, position, and course from the aorta and position relative to the usual renal artery trunk. Understanding of renal anatomy and the potential variability of the renal vasculature is essential to prevent iatrogenic injury.
