Open-cell stent and use of cone-beam CT enables a safe and effective coil embolization of true ophthalmic artery and anterior choroidal artery aneurysms with preservation of parent vessel: Clinical and angiographic results
Authors: Hou Samuel Y , Kühn Anna Luisa , Puri Ajit S , Wakhloo Ajay K
Published: December 2017

Background

Treatment of true ophthalmic artery (OA) or anterior choroidal artery (AChA) aneurysms with preservation of the parent vessel may be challenging. Flow diverters have limitations when dealing with branch vessels arising from the aneurysm sac. Visual loss or AChA territory infarcts have been reported both for surgical and endovascular treatment.

Methods

We evaluated the safety and efficacy of an open-cell design, laser-cut, self-expanding Nitinol stent, and use of cone-beam computed tomography (CBCT) for stent-assisted coil embolization.

Results

A total of seven patients with unruptured OA or AChA aneurysms were enrolled in this prospective small case study and the data were analyzed retrospectively. A complete obliteration was achieved in all aneurysms immediately post-intervention or at six-month follow-up without any evidence for recanalization at up to three-year follow-up. All patients tolerated the procedure well and there was no change in baseline modified Rankin Scale.

Conclusions

Our study suggests that specific features of an open-cell stent allow a safe and effective treatment of OA or AChA aneurysms with a high technical success rate and excellent mid-term angiographic and clinical outcome. CBCT is a useful intraoperative imaging tool.
Recurrent posterior circulation infarcts secondary to vertebral artery external compression treated with endovascular deconstruction
Authors: Berti Aldo Fabrizio , Zafar Atif , Ikram Asad , Calder Christopher S , Sorte Danielle Eckart
Published: December 2017

When multiple, recurrent infarcts occur in spite of maximal medical management, the level of suspicion for atypical vascular injury should be heightened. We present a case of a patient who presented with recurrent posterior circulation infarcts despite optimized medical management. On imaging, he was found to have external anatomical vertebral artery muscular and/or osseous compression leading to repetitive vascular injury and strokes. Recurrent intimal injury and vertebral artery to intracranial emboli despite anticoagulation and subsequent dual antiplatelet therapy necessitated definitive operative management. Surgical bypass, external surgical decompression, reconstructive endovascular, and deconstructive endovascular techniques were carefully considered. A deconstructive endovascular approach was chosen as the least morbid option. The use of endovascular plugs such as a microvascular plug provides a quick and effective means of achieving a therapeutic parent artery occlusion in lieu of traditional coil occlusion. Although reserved as a last resort, parent artery occlusion can be a viable option to treat recurrent strokes, particularly in a nondominant vertebral artery.
Sacral nerve stimulation versus intravesical botulinum toxin injections for medically refractory overactive bladder: A contemporary review of UK treatment from both clinician and patients’ perspectives
Authors: Nobrega R , Greenwell TJ , Pickard R , Ockrim JL , Harding CK
Published: December 2017

Introduction:

In the UK, 10,000 refractory overactive bladder patients per year receive intravesical onabotulinum toxin A treatment and 300 receive sacral nerve stimulation implants. Current National Institute for Health and Care Excellence guidelines propose using onabotulinum toxin A before sacral nerve stimulation whilst the European Association of Urology (EAU) and American Urological Association (AUA) suggests both be offered with equipoise. The aim of this study was to ascertain both patients and clinician views regarding these two treatments.

Subjects/methods:

Fifty consecutive overactive bladder patients who were refractory to behavioural and medical therapy anonymously completed a structured questionnaire about their treatment preferences. Additionally, 100 UK consultant urologists anonymously completed a separate questionnaire about their treatment preferences and which treatment modalities they had available for use in their Trusts.

Results:

Of patients, 60% preferred sacral nerve stimulation over onabotulinum toxin A, of whom 80% would happily randomise into a trial between the two treatments. Ninety-seven per cent of 100 consultant urologists in the UK have access to onabotulinum toxin A in their hospitals, but only 39% have access to sacral nerve stimulation. Of clinicians given access to all available options, 71% would use onabotulinum toxin A as their first choice treatment for refractory overactive bladder.

Conclusion:

There appears to be a significant disparity between current UK overactive bladder guidance, National Health Service accessibility to onabotulinum toxin A and sacral nerve stimulation therapies, the views of clinicians, and patient preferences for treatment.

Hoffa Fragments in the Geriatric Distal Femur Fracture: Myth or Reality?
Authors: Hill Brian W. , Cannada Lisa K.
Published: December 2017

Background:

Previous research reported the frequency of coronal plane (Hoffa) fractures in high-energy supracondylar femur fractures in a relatively young population. It is the purpose of this study to identify the frequency of coronal plane fractures seen in elderly patients.

Methods:

All patients over the age of 18 years treated for supracondylar femur fractures at 2 level I trauma centers were reviewed over a 4-year period. The patients were stratified (≥60 years and <60 years) and compared to determine differences in injury characteristics and fracture patterns with special attention to the prevalence of coronal plane fractures.

Results:

One hundred ten patients were identified with supracondylar femur fractures (12 Orthopaedic Trauma Association [OTA] 33A; 2 OTA 33B; 96 OTA 33C). Thirty-two of the 96 intercondylar fractures were in patients >60 years of age. The elderly group included a higher percentage of females (81% vs 36%, P = .0001) and was more likely to sustain their injury due to a fall (59% vs 19%, P = .0001). Coronal plane fractures were visualized on computed tomography scans in 56 (58%) of the 96 33C femur fractures. Forty-four percent of elderly patients sustained a coronal plane fracture compared with 66% of the younger cohort ( P = .04). The percentage of open fractures (30% elderly vs 46%) was not significantly different between the 2 groups ( P = .17).

Conclusions:

The occurrence rate of 44% in this study was higher than expected and is the first to provide this information in the elderly patients on this fracture. It is important that a high index of suspicion be maintained for the Hoffa fracture in all distal femur fractures, regardless of age or mechanism of injury.
With Malice Towards All? Moral Authority, Violence, and the (Affective) Discipline of Basketball (Bodies)
Authors: Kurtz Jeffrey B.
Published: December 2017

This article examines National Basketball Association Commissioner David Stern’s press conference on November 21, 2004, in response to the brawl between the Detroit Pistons and Indiana Pacers 2 days earlier, during which he announced the suspensions of nine players. Specifically, I illuminate the ways the tropes of authority and discipline converged to fashion a rhetorical site of absolute professionalism that profoundly altered understandings of race, masculinity, and power. Stern’s prepared remarks and verbal exchanges with reporters, I contend, invite a reconsideration that examines more closely the cocktail of violence, authority, professionalism, and genuine moral struggle that plays out within the text. If that cocktail was tinged with putative racism and masculine domination, Stern’s presser (i.e., the full press conference) challenges scholars of sport to reflect upon the complex affective dynamics of institutional leadership and the obligations of professionalism, dynamics overlooked in recent analyses of the brawl and its aftermath. These dynamics present a compelling heuristic with which to “work through” our social anxiety over morality and sports.
Predictors of Entering a Hearing Aid Evaluation Period: A Prospective Study in Older Hearing-Help Seekers

Published: December 2017

This study aimed to determine the predictors of entering a hearing aid evaluation period (HAEP) using a prospective design drawing on the health belief model and the transtheoretical model. In total, 377 older persons who presented with hearing problems to an Ear, Nose, and Throat specialist ( n = 110) or a hearing aid dispenser ( n = 267) filled in a baseline questionnaire. After 4 months, it was determined via a telephone interview whether or not participants had decided to enter a HAEP. Multivariable logistic regression analyses were applied to determine which baseline variables predicted HAEP status. A priori, candidate predictors were divided into ‘likely’ and ‘novel’ predictors based on the literature. The following variables turned out to be significant predictors: more expected hearing aid benefits, greater social pressure, and greater self-reported hearing disability. In addition, greater hearing loss severity and stigma were predictors in women but not in men. Of note, the predictive effect of self-reported hearing disability was modified by readiness such that with higher readiness, the positive predictive effect became stronger. None of the ‘novel’ predictors added significant predictive value. The results support the notion that predictors of hearing aid uptake are also predictive of entering a HAEP. This study shows that some of these predictors appear to be gender specific or are dependent on a person’s readiness for change. After assuring the external validity of the predictors, an important next step would be to develop prediction rules for use in clinical practice, so that older persons’ hearing help-seeking journey can be facilitated.

Published: December 2017

Due to their unique properties, laser and optical technologies hold today an important role in the protection and study of Cultural Heritage, since they are used in a wide range of demanding analytical and diagnostic applications. Considering the rapid and vast technological development of their methodologies and tools, it is necessary to make this new knowledge more reachable and comprehensible to heritage scientists. Towards this end, a web-based knowledge platform (Polygnosis) (http://politeia.iesl.forth.gr/polygnosis/) was designed by the Institute of Computer Science (ICS) of FORTH concerning the state-of-the-art light and/or laser-based techniques, which have been developed at the Institute of Electronic Structure and Lasers (IESL) of FORTH, for advanced imaging, analysis and diagnosis of Cultural Heritage objects. This educational digital tool seeks to highlight the efficiency and potentials of modern optical and laser technologies in Cultural Heritage documentation, as well as, promote the dissemination and deeper understanding of their applications to conservators, archaeologists, art historians, material and laser scientists. “Polygnosis” represents accumulated knowledge regarding the selection of the diagnostic tool and the suggested methodology, with simultaneous display of examples of actual experimental procedures. The model relates those examples with the relevant terminology of the Thesaurus, the information about the object under examination and the metadata resulting from those experiments. ‘Polygnosis’ thesaurus is a semantically structured vocabulary organized by a faceted classification, which serves the educational needs of the system. The current study concerns the definition and classification of terms for the development of the semantically linked Thesaurus, as well as, the presentation and review of the knowledge platform, with emphasis on the supportive role of the thesaurus in such an educational resource.
Characterizing Dynamic Decay of Motion of Free-Standing Rocking Members
Authors: Kalliontzis Dimitrios , Sritharan Sri
Published: December 2017

Rocking is likely the primary dynamic mode of vibration during the earthquake response of free-standing structural members. Previous research has routinely described the dynamic behavior of these members using a coefficient of restitution ( r) modeling approach, which is shown in this paper to be insufficient for accurately capturing their decaying motion characteristics. Utilizing experimental testing and analytical investigation of concrete members, this study concludes that free-standing members dissipate energy in both a continuous manner and instantaneously at impacts at the rocking interface. Accounting for these two energy dissipation components is necessary to accurately produce rocking dynamic responses of free-standing blocks.
Multivariate Conversion of Moment Magnitude for Small-to-Moderate-Magnitude Earthquakes in Iran

Published: December 2017

Homogeneous estimates of moment magnitude (M) for small-to-moderate-magnitude (SMM) earthquakes are important to assess regional ground motion compared to global models. However, an estimate of M was available for only 6% of the shallow crustal earthquakes in Iran from 1973 to 2013 in the database developed by the Pacific Earthquake Engineering Research Center. Therefore, this study evaluates the existing conversion models, from ML, Ms, and m b, to M, for M > 4.0 using the Iranian data set. Correlations between the residuals of these conversions were computed. A weighted estimate for M is presented that combines these conversion models using these correlations based on multivariate statistics. The conversion to M was improved with smaller standard deviations, especially when ML and m b were both available. The inverse-variance–weighted approach, which is common in practice, underestimates the standard deviations because it neglects the positive correlations between these variables.
Consideration and Propagation of Ground Motion Selection Epistemic Uncertainties to Seismic Performance Metrics
Authors: Tarbali Karim , Bradley Brendon A. , Baker Jack W.
Published: December 2017

This paper investigates various approaches to propagate the effect of epistemic uncertainty in seismic hazard and ground motion selection to seismic performance metrics. Specifically, three approaches with different levels of rigor are presented for establishing the conditional distribution of intensity measures considered for ground motion selection, selecting ground motion ensembles, and performing nonlinear response history analyses (RHAs) to probabilistically characterize seismic response. The mean and distribution of the seismic demand hazard is used as the principal means to compare the various results. An example application illustrates that, for seismic demand levels significantly below the collapse limit, epistemic uncertainty in seismic response resulting from ground motion selection can generally be considered as small relative to the uncertainty in the seismic hazard itself. In contrast, uncertainty resulting from ground motion selection appreciably increases the uncertainty in the seismic demand hazard for near-collapse demand levels.
Performance Prediction Equations for Linear Planar Structural Systems: Concept, Formulation, and Validation
Authors: De Bortoli Marta , Zareian Farzin
Published: December 2017

This paper presents and validates an analytical formulation, denoted as Performance Prediction Equations (PPEs), that relates the seismic response engineering demand parameter (EDP) of buildings to earthquake parameters such as magnitude, epicentral distance, and type of faulting. PPEs are conceptually novel and can be readily included in any hazard calculation program to directly estimate EDP hazard curves. The PPEs presented herein are based on the linearization of response spectrum analysis (RSA) formulation for estimation of the seismic response of multi-degree-of-freedom (MDOF) models for planar structural systems. Equations for mean and variance are provided for floor displacement, interstory drift ratio, and normalized base shear. The input parameters needed to apply the proposed PPEs are the modal properties of the structural system and the selection of an existing ground motion model (GMM). The proposed PPEs are validated against simulated results using a set of planar building models and the Campbell-Bozorgnia 2014 GMM. The comparison confirms that the proposed PPEs provide an accurate estimate of the statistics of the said EDPs.

Published: December 2017

Purpose

For the past 65 years, patient age at diagnosis has been widely used as a major mortality risk factor in the risk stratification of papillary thyroid cancer (PTC), but whether this is generally applicable, particularly in patients with different BRAF genetic backgrounds, is unclear. The current study was designed to test whether patient age at diagnosis is a major mortality risk factor.

Patients and Methods

We conducted a comparative study of the relationship between patient age at diagnosis and PTC-specific mortality with respect to BRAF status in 2,638 patients (623 men and 2,015 women) with a median age of 46 years (interquartile range, 35 to 58 years) at diagnosis and a median follow-up time of 58 months (interquartile range, 26 to 107 months). Eleven medical centers from six countries participated in this study.

Results

There was a linear association between patient age and mortality in patients with BRAF V600E mutation, but not in patients with wild-type BRAF, in whom the mortality rate remained low and flat with increasing age. Kaplan-Meier survival curves rapidly declined with increasing age in patients with BRAF V600E mutation but did not decline in patients with wild-type BRAF, even beyond age 75 years. The association between mortality and age in patients with BRAF V600E was independent of clinicopathologic risk factors. Similar results were observed when only patients with the conventional variant of PTC were analyzed.

Conclusion

The long-observed age-associated mortality risk in PTC is dependent on BRAF status; age is a strong, continuous, and independent mortality risk factor in patients with BRAF V600E mutation but not in patients with wild-type BRAF. These results question the conventional general use of patient age as a high-risk factor in PTC and call for differentiation between patients with BRAF V600E and wild-type BRAF when applying age to risk stratification and management of PTC.

As tecnologias estão presentes nos processos e dinâmicas sociais e redesenham seu contexto em diversos âmbitos. Estas são alvo dos mais diversos sentimentos como euforia, receio, resistência ou adoção indiscriminada. Quando algo novo adentra o contexto social, de algum modo o reconfigura. Assim também têm sido as atuais tecnologias disponíveis nos smartphones. O Uber, serviço de transporte particular, repulsa taxistas e atrai consumidores. Este ensaio verifica a existência de relações entre os fenômenos precedentes observados por autores como Schumpeter e Christensen, e que foram representados no processo de formulação de suas teorias com a empresa Uber. Características capazes de classificar o modelo de negócios do Uber como uma “nova combinação” (SCHUMPETER, 1997) foram identificadas. Os direcionamentos tomados por essa indústria são discutidos neste ensaio através da distinção entre “tecnologias de sustentação”, utilizadas pelos táxis e “inovações disruptivas”, praticadas pelo Uber.

Hospitalist and Internal Medicine Leaders' Perspectives of Early Discharge Challenges at Academic Medical Centers
Authors: Patel Hemali , Fang Margaret C. , Mourad Michelle , Green Adrienne , Wachter Robert M. , Murphy Ryan D. , Harrison James D.
Published: December 2017

Improving early discharges may improve patient flow and increase hospital capacity. We conducted a national survey of academic medical centers addressing the prevalence, importance, and effectiveness of early‐discharge initiatives. We assembled a list of hospitalist and general internal medicine leaders at 115 US‐based academic medical centers. We emailed each institutional representative a 30‐item online survey regarding early‐discharge initiatives. The survey included questions on discharge prioritization, the prevalence and effectiveness of early‐discharge initiatives, and barriers to implementation. We received 61 responses from 115 institutions (53% response rate). Forty‐seven (77%) “strongly agreed” or “agreed” that early discharge was a priority. “Discharge by noon” was the most cited goal (n = 23; 38%) followed by “no set time but overall goal for improvement” (n = 13; 21%). The majority of respondents reported early discharge as more important than obtaining translators for non‐English‐speaking patients and equally important as reducing 30‐day readmissions and improving patient satisfaction. The most commonly reported factors delaying discharge were availability of postacute care beds (n = 48; 79%) and patient‐related transport complications (n = 44; 72%). The most effective early discharge initiatives reported involved changes to the rounding process, such as preemptive identification and early preparation of discharge paperwork (n = 34; 56%) and communication with patients about anticipated discharge (n = 29; 48%). There is a strong interest in increasing early discharges in an effort to improve hospital throughput and patient flow.
Experiencia con Símbolos y Comprensión de Dibujos en Niños Pequeños de Distintos Contextos Socioeconómicos
Authors: Salsa Analía M , Gariboldi María Belén
Published: December 2017

El propósito de esta investigación fue profundizar el estudio de la comprensión temprana de dibujos en niños de nivel socioeconómico medio (NSE medio) y bajo (NSE bajo) y examinar la influencia en este proceso de las experiencias con imágenes en el contexto familiar. Para ello, 28 niños de entre 30 y 38 meses resolvieron una tarea de correspondencias en la que debían establecer relaciones entre cinco objetos y sus dibujos en lápiz negro; sus madres contestaron un cuestionario sobre las experiencias infantiles con distintos tipos de imágenes (imágenes audiovisuales, fotografías y dibujos) y las prácticas entre adultos y niños con estas representaciones. Los resultados muestran que solamente los niños de NSE medio demostraron comprender la relación dibujo-referente; el desempeño simbólico se asoció principalmente con la presencia en los hogares de recursos con imágenes para niños (DVD y libros infantiles) y con las interacciones adulto-niño con estos recursos, como las experiencias conjuntas con imágenes audiovisuales, la lectura de cuentos y la asistencia materna al dibujar.

La Confederación Anticomunista Latinoamericana. Las conexiones civiles y militares entre Guatemala y Argentina (1972-1980)
Authors: Rostica Julieta
Published: December 2017

El ejercicio de la represión política en las zonas urbanas en Argentina y Guatemala desde mediados de los años setenta hasta mediados de los años ochenta, específicamente la desaparición forzada de personas, presenta varias similitudes. Nuestra hipótesis es que dichas similitudes se explican por la colaboración argentina en la lucha contrasubversiva en Guatemala a los órganos vertebrales que producen la desaparición forzada, como la inteligencia civil y militar. A nuestro juicio, la transferencia de recursos, conocimientos y experiencias de Argentina hacia Guatemala se  realizó no solamente a través de canales diplomáticos y oficiales, sino también a través de las conexiones civiles y militares (secretas, informales y clandestinas), como la red transnacional de extrema derecha denominada Confederación Anticomunista Latinoamericana (cal). En este artículo nos propusimos mostrar una de las condiciones de posibilidad para esa transferencia de recursos: la participación de la extrema derecha guatemalteca en la red latinoamericana de la cal y sus conexiones con Argentina. Para ello utilizamos, sobre todo, documentos desclasificados del Archivo Histórico de la Cancillería Argentina y del Centro de Documentación y Archivo para la Defensa de los Derechos Humanos de Paraguay.

En el marco de los recientes procesos de regionalización que vive América Latina como respuesta a la creciente multipolaridad e interdependencia que identifican el escenario global contemporáneo se configura un nuevo mapa de la integración regional que retoma y cuestiona los paradigmas tradicionales de inserción internacional. La Alianza del Pacífico (AP) se destaca como proyecto regional novedoso heredero del regionalismo abierto, con rasgos específicos que le imprimen una identidad propia aún en construcción. El objetivo del artículo es identificar las continuidades y las rupturas que evidencia la ap frente al regionalismo abierto como su marco teórico-conceptual  inspirador. Se concluye que la ap se configura en sus pocos años de existencia como un proceso distinto de experiencias previas de regionalismo abierto en América Latina, con rasgos específicos que no permiten reducir la comprensión de este actor regional a un estudio de caso típico del enfoque del regionalismo abierto.
Ni aquí ni allá: Nociones de hogar y sentido de pertenencia en el contexto de la migración.
Authors: Gomez Ricardo
Published: December 2017

La pregunta ¿dónde queda el hogar? es difícil, especialmente para los migrantes, quienes viven en un lugar diferente a su lugar de origen. Es particularmente difícil para aquellos que no tienen documentos y por lo tanto no tienen ni reconocimiento legal ni derechos, y están en constante riesgo de ser detenidos y deportados. A través de fotografía participativa y entrevistas, proceso que se ha llamado fotohistorias, se exploran experiencias humanas relacionadas con la migración en ee.uu., y en la frontera entre este y México. El artículo trata sobre las nociones contrapuestas relacionadas con el hogar y el sentido de pertenencia que surgieron en las experiencias compartidas por migrantes en estos dos contextos. Los migrantes evidenciaron diferentes nociones de “hogar” así como de “pertenencia”, que reflejan los diferentes grados de transitoriedad e impermanencia en su cotidianidad.
La múltiple audienciación de las sociedades contemporáneas: desafíos para su investigación
Authors: Orozco Guillermo
Published: December 2017

Al reconocer que a la par de una mediatización creciente y diferenciada de las sociedades contemporáneas se desarrolla una audienciación múltiple y contrastante de los sujetos sociales, se sostiene en este ensayo que “ser y estar” como audiencia es la situación y actividad más característica de los ciudadanos hoy, y que es en esa interacción con el mundo, siempre mediada por representaciones audiovisuales de sí mismos, de los otros y de lo otro desde donde se construye y se juega la ciudadanía. El entendimiento de esta realidad es una razón sustantiva para su investigación, la cual se propone implementar a través de hacer evidente: i) los modos en que las representaciones mediáticas y digítales asumen a su audiencia; ii) la forma dominante o alternativa en que la audiencia es representada en las narrativas o en sus propias representaciones en los productos transmedia, y iii) la manera en que las audiencias son interpeladas desde las pantallas o por otras audiencias.
Absence-Neglect and the Origins of Great Strategies
Authors: Powell Thomas C.
Published: December 2017

Great business strategies originate in a top management worldview that seeks to implement bold strategic change in the external world. This worldview generates confident strategic actions capable of producing extreme success. However, it also generates catastrophic failures and lower returns on average. This is because action-oriented managers pay abnormal attention to the observables of sense experience while neglecting the world of absence, a bias I refer to as absence-neglect. Absence-neglect is the cognitive tendency to notice presence more than absence—for example, movement more than stillness and noise more than silence. This paper examines the origins of absence-neglect and its consequences for strategy formation, firm performance, and social welfare. I argue that societies can reduce the economic and moral risks of “great” strategies by cultivating a more balanced discernment of presence and absence.
From Values to Value: Value Rationality and the Creation of Great Strategies
Authors: Rindova Violina P. , Martins Luis L.
Published: December 2017

This paper proposes that strategies with superior value-creation and value-capture potential—that is, great strategies—can originate in the personal values of strategists. We root our argument in Max Weber’s idea of value-rational action as an innate human capacity expressed in value rationality, which refers to actions that derive their logic with reference to a value system. We build on psychological research on personal values to propose that values are complex cognitive resources, distinct from mental representations, beliefs, ideologies, identities, and emotions, that, when deployed in strategy making, affect the attributes of the strategies created. We specify how values affect the value-creation and value-capture potential of firms’ strategies by theorizing four distinct functions of values in strategy making: as attentional structures, as valuation lenses, as design principles, and as identity markers. As attentional structures, values direct strategists’ attention to specific issues and often unconventional solutions; as valuation lenses, they change the evaluation of relevant markets and resources; as design principles, they influence the prioritization and integration of activities; and as identity markers, they facilitate audience engagement and mobilization. Our theory offers a new basis for understanding the sources of novel strategies and pathways to superior value creation by firms.
The Attention-Based View of Great Strategies
Authors: Ocasio William , Joseph John
Published: December 2017

For the attention-based view, the origins of the ideas behind a great strategy are less important than the ability of the organization to sustain focused attention in developing, implementing, and elaborating good ideas into a distinctive strategic agenda for value creation. We propose that the transformation of ideas into a great strategy is shaped by the firm’s identity and corresponding patterns of organizational attention. Furthermore, great strategies focus attention on creating value for the customer—through the firm’s value proposition and business model—relative to capturing value for the shareholders. Finally, we propose that great strategies emerge from a focused, strategic agenda communicated and distributed throughout the organization. We illustrate our propositions by comparing Apple and Motorola, which began with similar ideas for developing a strategy for seamless integration and seamless mobility, with smartphones as the digital hub. Apple sustained focused attention on transforming the ideas into the great strategy and business model behind the iPhone, while Motorola did not focus or sustain attention throughout the organization on developing its original ideas, leading to strategic failure.
Why Great Strategies Spring from Identity Movements
Authors: Rao Hayagreeva , Dutta Sunasir
Published: December 2017

We extend the emergent lens on strategy formulation by arguing that great strategies arise from insurgent identity movements. In motivating the paper, we depict Steve Jobs as an activist constituted by the personal computing movement that attacked corporate computing. We discuss the processes that mediate the link between great strategies and oppositional movements, and suggest that the strategist ought to be an activist rather than an analyst alone.
Nursing and the barriers to sustainable health care: a literature review
Authors: Griggs Chloe , Fernandez Ana , Callanan Margie
Published: December 2017

Objectives:

global warming poses a serious threat to human health, yet healthcare organisations and staff have been relatively slow to engage with sustainable healthcare practices. This review of the literature seeks to frame what is already known about nurses and their views on global warming and sustainable health care.

Design:

11 primary research articles were sourced from a search of five mainstream databases. These articles were subject to a basic thematic analysis.

Results:

six themes were identified: sustainability, endemic blindness to global issues, environmental numbness, social norms, priority assigned to sustainability, and psychology of responsibility and blame.

Conclusion:

from the literature reviewed, there are a number of social, cultural and psychological barriers that have led to widespread inaction. This article recommends further research to understand the psychological barriers in more depth as this is a poorly understood area.

Mild bleeding disorders: what every clinician should know
Authors: Hussein HK , Nicolson PLR , Fordwor K , Lowe GC
Published: December 2017

Patients with mild bleeding disorders are under-recognized and frequently present to general physicians. The underlying reasons for bleeding are multifactorial. There is little evidence to guide diagnostic and management decision making in patients with mild bleeding disorders.

This article outlines different types of mild bleeding disorders, with a particular focus on bleeding associated with low levels of von Willebrand factor and mild platelet defects. It gives practical, evidence-based advice on the investigation and management of patients with a suspected or known mild bleeding disorder, considering the scenarios of an acute bleed, stable outpatient, peri-surgical management and thrombosis.

Patients with a mild bleeding disorder have variable bleeding because of the interplay of genetic and environmental factors. The clinical history remains of utmost importance in their general management. Liaison with a specialist centre, multidisciplinary assessment and a careful judgement of the balance of risk in each individual circumstance is required to safely manage these patients.

Reading History into Law: Who Is Worthy of Reparations? Observations on Spain and Portugal's Return Laws and the Implications for Reparations
Authors: Jinan Bastaki
Published: December 2017

In 2015, both Portugal and Spain passed similar laws offering Sephardic Jews their respective citizenships to redress the historic wrong of their persecution and expulsion under the Inquisition. Portugal and Spain are now the only other countries in the world to have a return law for the Jewish people, in addition to Israel—albeit limited to Sephardic Jews. Given the underlying reasons for the passing of this law, it is notable that Iberian Muslims, who were also expelled, have no recourse for redress—not even symbolically. While remedies can be limited under international law, this article explores the relationship between the historical narrative of the Arab/Muslim occupiers, the current popular portrayal of Muslims in the Iberian Peninsula, and the relationship between the absence of reparations and current discrimination against groups.

Experiencia en metodologías activas: proyecto para las asignaturas Introducción a la Contabilidad y Contabilidad Financiera en el Grado de Relaciones Laborales y Recursos Humanos de la UPV/EHU
Authors: Saitua Iribar Ainhoa , Vázquez Arias Isabel
Published: December 2017

Este artículo presenta los resultados de la experiencia en la implementación del Aprendizaje Basado en Proyecto (ABPy) para las asignaturas de Contabilidad en el grado de Relaciones Laborales y Recursos Humanos. Hemos podido comprobar que el alumnado puede aprender de forma alternativa a la tradicional. La formulación de una pregunta motriz como eje de un proyecto ayuda a visualizar la utilidad de cada una de las asignaturas en la vida real y, por lo tanto, entendemos que fomenta la motivación del alumnado. Sin embargo, desde el curso 2013/2014, en el que se produjo la primera implantación de la metodología de ABPy, hasta el curso 2016/2017, la tasa de rendimiento ha disminuido en todos los grupos. Así, creemos que por mucho esfuerzo pedagógico que realice el profesorado, es el alumnado quien finalmente determina con sus capacidades iniciales y, después, con su asistencia, actitud y esfuerzo continuado en el tiempo, el mayor o menor éxito en su proceso de aprendizaje y, finalmente, su nivel de éxito en la superación de las materias correspondientes

En este artículo trataré de explicar en qué ha consistido el Proyecto de Innovación Educativa “Los podcast como método de aprendizaje autónomo en la asignatura de Derecho del Trabajo y de la Seguridad Social en la Universidad del País Vasco / Euskal Herriko Unibertsitatea” (PIE 25, 2015-2017) −en el que hemos participado profesorado de dos Universidades[1]−, cómo se ha implementado, cuáles son las dificultades con las que nos hemos encontrado en ese proceso, resultados obtenidos y cuáles son las conclusiones a las que hemos llegado.[1] De la UPV/EHU: Olga Fotinopoulou Basurko (coord.), María Aránzazu Martínez Balmaseda, Amaya Martínez de Viergol Lanzagorta, Koldo Irurzun Ugalde, Elisabet Errandonea Ulazia, Eider Larrazabal Astigarraga, Miren Alazne Odriozola Landeras, Ana Isabel Zapirain Bilbao, Marta Arrue Mendizabal, María Nieves Martínez Gayoso, Garbiñe Biurrun Mancisidor y Miren Edurne López Rubia; y de la Universidad Jaume I de Castellón: Aranzazu Vicente Palacios, Sara Ruano Albertos e Inmaculada Ballester Pastor.
“Érase una vez…”: la creación de historias como herramienta de aprendizaje activo en el grado en relaciones laborales y recursos humanos
Authors: Fernández del Río Elena , Berges Saldaña Alfredo , Ramos Villagrasa Pedro José
Published: December 2017

La creación de historias o storytelling constituye una herramienta útil en la enseñanza universitaria en cuanto promueve en los estudiantes un aprendizaje más activo. Esto es especialmente relevante en el ámbito de las Relaciones Laborales y Recursos Humanos (RLRH), ya que la historia creada refleja situaciones concretas relacionadas con el comportamiento humano dentro del ámbito laboral. El objetivo de este trabajo es analizar los resultados obtenidos tras la introducción del storytelling con 111 alumnos matriculados en una asignatura del Grado en RLRH de la Universidad de Zaragoza. Los resultados indican que aquellas actividades que implican un aprendizaje integral y activo, como la construcción de una historia, repercuten significativamente en el rendimiento académico, además de contribuir a una mayor percepción de utilidad y satisfacción del alumnado. En este sentido, se plantea la idoneidad de generalizar este tipo de herramientas didácticas a otras asignaturas del Grado vinculadas a diferentes áreas de conocimiento.
El aprendizaje colaborativo: una metodología eficaz para la enseñanza del Derecho Procesal Laboral
Authors: Sánchez-Rubio Ana
Published: December 2017

El Grado en Relaciones Laborales y Recursos Humanos no posee un campo de conocimientoúnico sino que está configurado de manera híbrida, dado que engloba porigual conocimientos jurídicos y de gestión del personal. En concreto, en lo que respectaal Derecho procesal, el plan de estudios no contempla ninguna asignatura introductoriaque permita a los alumnos establecer una primera toma de contacto con la terminologíay la dinámica de esta disciplina. Por ello, a los estudiantes les resulta especialmentecomplejo enfrentarse a asignaturas como Derecho procesal laboral. Con elpropósito de mitigar dicha sensación de dificultad, en las siguientes líneas se expondrándistintas técnicas docentes enfocadas hacia un modelo de clase colaborativa, enla que tanto los alumnos como el docente construyen la materia objeto de estudio alunísono, ya que hacer partícipe al alumno es el modo más eficaz de aprendizaje.
La homogenización de contenidos en el duopolio privado de televisión en España: Atresmedia y Mediaset
Authors: Medina-Nieto Margarita
Published: December 2017

El artículo presenta un análisis comparativo entre las dos plataformas privadas de televisión más importantes de España. Se ofrece un análisis de contenido de los cuatro canales de mayor audiencia de Atresmedia y Mediaset (canales generalistas y temáticos) para demostrar empíricamente que ambos grupos mediáticos tienen una estrategia programática muy similar que acucia, más si cabe, la falta de pluralismo en el panorama mediático español. Se concluye, a través de la presentación de gráficos comparativos entre las cadenas homólogas, que se dan significativas coincidencias en la tipología y estrategia programática de ambas plataformas.

Asimismo, pretende visibilizar y recuperar la figura de Enrique Ortega como creador gráfico con una primera semblanza biográfica. Un trabajo que le aborda por primera vez reivindicándolo como uno de los ilustradores clave para redibujar la transición española.
El Genio (1874-1875): La primera revista periódica que insertó fotografías
Authors: Chomón Serna José María , Moreno Gallo Miguel Ángel
Published: December 2017

El Genio fue pionero en el uso de la fotografía como elemento icónico en la prensa. La Diputación Provincial de Burgos conserva un ejemplar del año 1875, en el que se insertan fotografías a la albúmina en ejemplares de tipografía mediante un ingenioso sistema de pegado en espacios en blanco. Aunque hay precedentes de la inserción de páginas con imágenes fotográficas en libros ilustrados, por vez primera los lectores pudieron contemplar testimonios reales icónicos en una revista periódica. El Genio fue obra de la familia Martínez Añibarro.
