Heritability of language laterality assessed by functional transcranial Doppler ultrasound: a twin study
Authors: Bishop Dorothy V.M. , Bates Timothy C.
Published: March 2020

Background: Prior studies have estimated heritability of around 0.25 for the trait of handedness, with studies of structural brain asymmetry giving estimates in a similar or lower range. Little is known about heritability of functional language lateralization. This report describes heritability estimates using functional language laterality and handedness phenotypes in a twin sample previously reported by Wilson and Bishop (2018).

Methods: The total sample consisted of 194 twin pairs (49% monozygotic) aged from 6 to 11 years. A language laterality index was obtained for 141 twin pairs, who completed a protocol where relative blood flow through left and right middle cerebral arteries was measured using functional transcranial Doppler ultrasound (fTCD) while the child described animation sequences. Handedness data was available from the Edinburgh Handedness Inventory (EHI) and Quantification of Hand Preference (QHP) for all 194 pairs. Heritability was assessed using conventional structural equation modeling, assuming no effect of shared environment (AE model).

Results: For the two handedness measures, heritability estimates were consistent with prior research: 0.23 and 0.22 respectively for the EHI and QHP. For the language laterality index, however, the twin-cotwin correlations were close to zero for both MZ and DZ twins, and the heritability estimate was zero.

Conclusions: A single study cannot rule out a genetic effect on language lateralisation. It is possible that the low twin-cotwin correlations were affected by noisy data: although the split-half reliability of the fTCD-based laterality index was high (0.85), we did not have information on test-retest reliability in children, which is likely to be lower. We cannot reject the hypothesis that there is low but nonzero heritability for this trait, but our data suggest that individual variation in language lateralisation is predominantly due to stochastic variation in neurodevelopment.
Stay True to Your Roots? Category Distance, Hierarchy, and the Performance of New Entrants in the Music Industry
Authors: Younkin Peter , Kashkooli Keyvan
Published: March 2020

New entrants in established markets face competing recommendations over whether it is better to establish their legitimacy by conforming to type or to differentiate themselves from incumbents by proposing novel contributions. This dilemma is particularly acute in cultural markets in which demand for novelty and attention to legitimacy are both high. We draw upon research in organizational theory and entrepreneurship to hypothesize the effects of pursuing narrow or broad appeals on the performance of new entrants in the music industry. We propose that the sales of novel products vary with the distance perceived between the classes being combined and that this happens, in part, because combinations that appear to span great distances encourage consumers to adopt superordinate rather than subordinate classes (e.g., to classify and evaluate something as a “song” rather than a “country song”). Using a sample of 144 artists introduced to the public via the U.S. television program The Voice, we find evidence of a U-shaped relationship between category distance and consumer response. Specifically, consumers reward new entrants who pursue either familiarity (i.e., nonspanning) or distinctive combinations (i.e., combine distant genres) but reject efforts that try to balance both goals. An experimental test validates that manipulating the perceived distance an artist spans influences individual evaluations of product quality and the hierarchy of categorization. Together these results provide initial evidence that distant combinations are more likely to be classified using a superordinate category, mitigating the potential confusion and legitimacy-based penalties that affect middle-distance combinations.
Competition, Technology Licensing-in, and Innovation
Authors: Moreira Solon , Klueter Thomas Maximilian , Tasselli Stefano
Published: March 2020

Although the relationship between competition and firm innovation has long been of scholarly interest, prior research has predominantly considered changes in internal research and development (R&D) as a strategic response to competitors’ actions. In this study, we focus on one of the most important and commonly observed contractual mechanisms used to acquire external technologies: technology licensing. Surprisingly, licensing has been mostly overlooked by prior studies examining the effect of competition on firms’ allocation of R&D. We take into account the unique properties of licensing and systematically link them to the demands arising from the competitive pressure caused by rivals’ launches of new products. Furthermore, we discuss how licensing-in decisions ultimately shape a firm’s subsequent innovation in areas where they are threatened by competitors and how such innovation depends on the cumulative R&D investments inside the organization into which licensed knowledge is added. We test our theoretical model through a longitudinal design that tracks the licensing-in and innovation outcomes of firms in the global biopharmaceutical industry. Accounting for the endogenous selection of firms into licensing, our findings illustrate that licensing-in is motivated by competitive pressures. We also find that licensing-in increases a firm’s capacity to innovate in areas where competitors have exerted pressure, particularly in the presence of cumulative R&D investments. In so doing, the paper anchors technology licensing as a key organizational action that helps increase our understanding of the important relationship between competition and innovation.
Female survivors’ experiences of authorities’ actions in cases of partner stalking
Authors: Puronvarsi Nelli , Ruotanen Viivi , Holma Juha
Published: March 2020

Previous studies have shown that civil authorities fail to understand the nature of stalking and the harmful consequences it causes victims. The aim of this study was to investigate how the victims of partner stalking had perceived the actions of civil authorities and the stalking investigation process. The data were drawn from conversations among members of an internet-based peer support group for female victims of partner stalking. We identified four main categories of victims’ experiences pertaining to authorities’ actions and the investigation process: authorities’ problems in dealing with stalking, dissatisfaction with the investigation process, trust in the authorities and expectations of future actions by the authorities. Negative experiences were clearly foregrounded in the data. The results indicate that civil authorities continue to have problems in dealing with stalking. Authorities, especially the police, representatives of the justice system and child protection personnel should be offered more comprehensive education to enable them to deal more effectively when encountering female stalking victims.
La tradició grega del culte de Cebrià d'Antioquia i Santa Justina a Catalunya
Authors: Camps Gaset Montserrat
Published: March 2020

El culte de Cebrià d’Antioquia i santa Justina té l’origen en un text grec apòcrif del segle IV i des dels inicis s’ha confós amb la biografia de sant Cebrià, bisbe de Cartago. A Catalunya hi ha diverses esglésies antigues dedicades a un dels dos, i no sempre queda clara la diferència. Alguns dels goigs cantats en honor del sant donen testimoni de l’antiga llegenda oriental i de la confusió amb el bisbe. Aquí es presenta una proposta d’identificació d’una màrtir desconeguda que apareix al retaule de sant Cebrià de Cabanyes, del segle XV.
L’humanisme medieval de Joan Rois de Corella
Authors: Garriga Carles
Published: March 2020

Joan Roís de Corella usa el tema de l’escala dels éssers i el de l’ànima bestialitzada pels vicis usant exemples de la tradició clàssica però en realitat la ideologia i els principis morals amb què ho fa depenen del desenvolupament que la moralitat cristiana ha fet d’aquells temes. L’un i l’altre es troben units en el text sobre la disputa entre Àiax i Ulisses, on Corella els usa d’una manera tal que són una representació de la seva pròpia actitud com a escriptor.
La alternancia predicativa en español
Authors: Agenjo Recuero Dolores
Published: March 2020

En español, la alternancia predicativa (tener granos en la cara / tener la cara con granos) difiere de la alternancia locativa (cargar el heno en el camión / cargar el camión con heno) en tres aspectos relevantes: (i) argumentos verbales, (ii) estructura eventiva y (iii) relación semántica entre el significado verbal de la variante de locado y el significado verbal en la variante de locación. Por otra parte, el tipo de construcciones propio de la alternancia predicativa no solo se combina con verbos estativos, sino también con verbos aspectualmente dinámicos, incluidos los más representativos de la alternancia locativa. En conclusión, sostenemos que la alternancia predicativa constituye un tipo de diátesis verbal distinto e independiente de la alternancia locativa.
Subjectivació i evidencialitat: El verb "amenaçar" fins al segle XIX. Un estudi de corpus
Authors: Antolí Martínez Jordi M.
Published: March 2020

En català actual, el verb amenaçar coneix, juntament amb un valor lèxic (amb subjecte agent), un valor d’auxiliar evidencial (segons la definició de Cornillie 2016) que permet realitzacions com: amenaçava de ploure (DIEC2, s. v. amenaçar, 3; DDLC, s. v. amenaçar, 5). El desplegament d’aquest valor ha estat explicat, per al cas de l’anglès (com a epistèmic: Traugott 1997) i de l’espanyol (Cornillie 2007, 2016; Cornillie i Octavio de Toledo 2015), amb el concepte de subjectivació (d’acord amb la proposta de Traugott i Dasher 2002). Seguint aquesta línia de recerca, en aquest estudi provem de descriure i explicar el procés de canvi pel qual aquest verb desenvoluparà, en català, el valor epistèmic/evidencial durant l’època moderna, en un procés que culminarà ja en el segle XIX. La recerca es fonamentarà en el buidatge i anàlisi de dades de corpus textuals informatitzats del català antic, modern i contemporani. Les dades obtingudes seran analitzades qualitativament i quantitativa, i interpretades mitjançant les eines teòriques de què ens forneix la Lingüística Cognitiva i la Gramàtica de Construccions basada en l’ús d’acord amb la proposta de Traugott i Trousdale (2013) i la Invited Inferencing Theory of Semantic Change (IITSC) de Traugott (2012).
Aplicación del modelo bioecológico en Educación Física en contextos de exclusión social
Authors: Lamoneda Prieto Javier
Published: March 2020

El objetivo del presente estudio fue implementar un programa de educación física (EF) basado en el modelo bioecológico y valorar a través de la opinión de los participantes el grado de interés y beneficio social que les reportó. Participaron 151 estudiantes con una edad media de 14.39 años (± 1.62) pertenecientes a un centro de Secundaria en una zona en riesgo de exclusión. Se emplearon cuatro áreas de actuación: recreos activos, actividades inter-centro, contacto con entidades locales y actividades en el medio natural. El cuestionario presentó una adecuada consistencia interna (entre α = .63 y α = .83). Los resultados revelaron un nivel satisfactorio en las dos variables analizadas: interés y beneficio social (entre M = 3.78 y M = 3.94). El contacto con entidades deportivas y la práctica de actividades en el medio natural resultaron ser las medidas de actuación idóneas para trabajar con adolescentes independientemente del curso y género.
El acercamiento al tratamiento pedagógico de lo corporal a través de la participación en una comunidad de práctica virtual
Authors: Bores García Daniel , González Calvo Gustavo , García Monge Alfonso
Published: March 2020

En el presente artículo de reflexión se traza el camino recorrido por un docente hasta su participación en (Re)Produce, una comunidad de práctica virtual para profesionales de Educación Física en la que, durante tres cursos escolares, intercambia experiencias, opiniones y conocimientos con varias decenas de profesores de las diferentes etapas educativas y con docentes en formación inicial. Esta vivencia permite al investigador conocer una nueva manera de entender la Educación Física, desconocida para él hasta el momento. A través de fragmentos del diario personal y de los textos de los hilos de discusión de la comunidad de práctica virtual se recorrerá el camino del docente hasta el acercamiento al Tratamiento Pedagógico de lo Corporal, visión educativa que deja una huella indeleble en su identidad profesional.
La fonética en el aula de Bachillerato. Una propuesta basada en los nuevos modelos de análisis
Authors: Casado Mancebo Mario
Published: March 2020

Tras la última ley educativa, la fonética ha sido apartada del currículo oficial de Lengua castellana y Literatura. Aunque en las leyes anteriores apenas se les dedicaba un epígrafe en la programación, esa mínima presencia permitía recordar que los estudios de lingüística no han de reducirse a análisis sintácticos o morfológicos, realizados frecuentemente de un modo mecánico. El objetivo de este trabajo, además de proponer una secuencia didáctica basada en conceptos relativos al nivel fónico, es demostrar de forma argumentada la importancia del estudio de la fonética. En este trabajo se proporciona un enfoque renovado: basado, por una parte, en recientes investigaciones sobre fonética; alejado, por otra, de la teoría tradicional, caracterizada por su engañosa sencillez y claridad. Sin renunciar a una exposición científica rigurosa, sustento de cualquier estudio, se ofrece una unidad didáctica para abordar los conceptos fundamentales de la fonética.

Educación musical en el panorama español. Contexto, niveles y perfiles educativos
Authors: Vernia Carrasco Ana M.
Published: March 2020

Si pensamos en los retos actuales de la Educación Musical, podríamos pensar en la empleabilidad y en la formación, pues actualmente, la música se mueve en todos los ámbitos y contextos que nos podamos imaginar, traspasando lo que algunos investigadores puros llamarían código ético del investigador. Si nos planteamos los retos para el siglo XXI ya en el primer cuarto de este esperado siglo, es que algo no hicimos bien cuando nos planteamos estos retos a finales del siglo pasado. En este artículo se recogen algunas propuestas para los diferentes ámbitos, contextos y niveles educativos, donde la música está o debería de estar presente, no como una materia optativa, sino como una necesidad educativa. Hacemos un repaso del estado de la Educación Musical en la Educación Infantil, Primaria y Secundaria, escuelas de Música y conservatorios, universidad y otros posibles espacios de educación no formal e informal.

Pedagogías creativas y trabajo por proyectos en la formación musical en los Grados de Educación. El caso de la Facultad de Palencia
Authors: Peñalba Alicia , Blanco García Yurima
Published: March 2020

El presente artículo expone diversas experiencias llevadas a cabo en la formación musical universitaria, en los Grados de Educación Infantil, Primaria y Social de la Facultad de Educación de Palencia, Universidad de Valladolid. Tomando como referencia las pedagogías creativas y el trabajo por proyectos, se muestran propuestas desarrolladas por el alumnado en la clase de Música bajo un enfoque globalizador. Estos proyectos tratan de hacer frente a tres importantes retos que caracterizan la educación en el siglo XXI: el componente creativo de la educación, la responsabilidad social, y el uso de las Tecnologías de la Información y las Comunicaciones (TICs) de forma crítica y responsable. Las ideas pedagógico-musicales desarrolladas por Paynter, Delalande y Alcázar, y los proyectos de transformación social a través de la música –como el conocido “Sistema” de orquestas en Venezuela– se convierten en puntos de partida para generar nuevas experiencias pedagógicas en la formación inicial del profesorado y para dar respuesta a las demandas de la educación musical en nuestra sociedad.
El impacto social, emocional y académico de las experiencias musicales
Authors: García-Gil Desirée , Cuervo Calvo Laura
Published: March 2020

La influencia musical es un hecho determinante en la formación integral del individuo que implica diferentes ámbitos y perspectivas, entre las que destacan la educación escolar obligatoria, la educación no formal, el contexto social cercano, la formación superior, el desarrollo laboral y la relación entre iguales. Esta investigación analiza ocho historias de vida de alumnos egresados de una universidad pública madrileña. Los resultados ponen de manifiesto que la disciplina musical tiene mayor influencia en el rendimiento académico y en la socialización en la etapa de Secundaria, en detrimento de la Primaria; es en esta en la que se aprecia un mayor peso del repertorio aprendido. Se constata una relación directa entre la influencia docente y el afianzamiento vocacional, ambos a su vez desencadenantes de la elección del egresado de una trayectoria profesional en el ámbito musical. Las conclusiones señalan el poder personal, social y académico que tiene la didáctica del hecho sonoro, por lo que se hace determinante y necesario la presencia de modelos educativos idóneos en las aulas y la apuesta por un profesorado bien formado, con capacidad para innovar y motivar al alumnado.
Switchable generation of a sub-200  fs dissipative soliton and a noise-like pulse in a normal-dispersion Tm-doped mode-locked fiber laser
Authors: Zhao Yiwu , Zhao Desheng , Liu Runmin , Ma Wanzhuo , Wang Tianshu
Published: March 2020

We report on the switchable generation of a dissipative soliton (DS) pulse and a noise-like pulse (NLP) in an all-fiberized Tm-doped fiber laser in the normal-dispersion region. Mode-locking operation is achieved through a nonlinear polarization rotation component, and the cavity dispersion is compensated using ultra-high numerical aperture (UHNA4) fiber that is easy to integrate and low in cost. At a pump threshold of 510 mW, DS operation can first be achieved without additional filter. The 3 dB spectrum bandwidth of the DS pulse is greater than 50 nm, and the duration of the de-chirped pulse is 193 fs. By increasing the pump power to 880 mW, the mode-locking state can evolve into NLP operation with proper cavity polarization state. The 3 dB spectrum bandwidth and duration of de-chirped coherence spike are 105.6 nm and 121 fs, respectively. Meanwhile, ultra-broadband NLP (over 150 nm considering 3 dB spectrum width) can also be observed with the appropriate cavity parameters. All the proposed pulse patterns present good capacity for achieving narrow pulse width and withstanding high pulse energy.
All-optical 3R regeneration for DPSK signal based on a semiconductor optical amplifier scheme
Authors: Mao Yaya , Liu Bo , Zhao Delin , Sun Tingting , Zhao Lilong , Ullah Rahat , Wu Yongfeng
Published: March 2020

This paper presents experimental demonstration of an all-optical 3 R (re-amplification, re-shaping, re-timing) regeneration scheme for differential phase-shift keying (DPSK) signals, which consists of a clock recovery module and a phase-regeneration module. The clock recovery module is based on a mode-locked fiber laser, and the optical clock is extracted with low timing jitter of 29 ps from a degraded 10 Gb/s DPSK signal. The phase regenerator consists of a one-bit delay interferometer demodulation stage and a semiconductor optical amplifier in which cross-phase modulation and nonlinear polarization rotation occur simultaneously. The results show that, after 3 R regeneration, the receiver sensitivity is improved by more than 1.6 dB for a bit error rate of 1 E-9.
The production of knowledge in Brazilian social movement families
Authors: Sartoretto Paola , Custódio Leonardo
Published: March 2020

Analyses of the interplay between media technologies and social movements have been predominantly media-centric, focusing on practices and orientations towards media. Studies looking into communication and media practices within social movements usually have the single social movement as a unit of analysis, overlooking relations and interactions among social movements. We shift the focus to practices and orientations towards media, and to communicative processes among social movement families. The study pays particular attention to communication related to the production and circulation of knowledge. Through the study of the interrelations among three social movements in Brazil, we propose a typology of knowledge constructed and circulated within and among social movements as related to 1) militancy and insurgency, 2) mobilisation dynamics, and 3) framing awareness.

What is Communicable? Unaccounted Injuries and “Catching” Diabetes in an Illegible Epidemic
Authors: Moran-Thomas Amy
Published: March 2020

Long-accepted models of causality cast diseases into the binary of either “contagious” or “non-communicable,” typically with institutional resources focused primarily on interrupting infectious disease transmission. But in southern Belize, as in much of the world today, epidemic diabetes has become a leading cause of death and a notorious contributor to organ failure and amputated limbs. This ethnographic essay follows caregivers’ and families’ work to survive in-between public health categories, and asks what responses a bifurcated model of infectious versus non-communicable disease structures or incapacitates in practice. It proposes an alternative focus on diabetes as a “para-communicable” condition—materially transmitted as bodies and ecologies intimately shape each other over time, with unequal and compounding effects for historically situated groups of people. The article closes by querying how communicability relates to community, and why it matters to reframe narratives about contributing causalities in relation to struggles for treatment access.
Populist Becoming: The Red Shirt Movement and Political Affliction in Thailand
Authors: Seo Bo Kyeong
Published: March 2020

In this article, I explore the ways in which political subjectivities take shape through populist mobilization and dissipation. While the rise and increasing electoral success of populist movements across the world are largely attributed to charismatic leadership that conjures the will of “the people,” much less known is how people become populist subjects at a particular historical juncture. By attending to personal accounts of participation and detachment in a mass movement known as the Red Shirts in Thailand, I explore how the politics of becoming that emerges from this movement obfuscates the conventional distinction between populist and democratic identification. The articulation of populist subjects’ aspiration and affliction provides a window into the undetermined aspects of political mobilization from the realm of the ordinary.

본 논문은 포퓰리즘 운동의 확대와 해소 과정에서 정치적 주체성이 만들어지는 다양한 양상을 탐구한다. 포퓰리즘 정치의 전세계적 성장과 선거 정치에서 커져가는 영향력은 흔히 대중 혹은 인민의 의지를 결집시킬 수 있는 카리스마적 지도자의 성공과 등치되어 왔다. 그러나 과연 어떻게 대중 혹은 인민이 특정한 역사적 시점에서 포퓰리스트가 되는가에 대해서는 충분한 논의가 이루어지지 못한 바 있다. 이러한 문제의식을 바탕으로 본 논문은 태국 레드셔츠 운동의 흥망성쇠를 경유한 한 개인의 삶 경험을 탐색하고, 이를 통해 대중 운동에 기반한 되기(becoming)의 정치가 포퓰리즘과 민주주의에 대한 관습적 구분을 흐트러트리는 양상에 주목한다. 포퓰리스트 주체성을 고무하는 복잡한 정동과 의미들은 민주주의 정치를 저해하는 병폐가 아니며, 역으로 정치적 주체성의 새로운 형식들이 만들어지고 작동하는 방식을 핵심적으로 보여준다. 포퓰리스트 주체들의 변화에 대한 열망과 수난의 경험은 일상의 영역에서부터 정치적 동원의 아직 결정되지 않은, 불확정적 속성을 드러낸다.
Speculative Fields: Property in the Shadow of Post-Conflict Colombia
Authors: Morris Meghan L.
Published: March 2020

In Colombia’s attempts to bring its decades-long conflict to a close, the state engaged in a broad endeavor to bring about a new era: the “post-conflict.” Land restitution, which aims to return and title land to those who lost it in the conflict, was billed as part of the path to peace. In the shadow of the post-conflict, however, restitution has given rise to speculation on uncertain market and legal regimes, as well as regimes of violence, which I explore drawing on ethnographic fieldwork in the region of Urabá. Speculative possession of land calls up historical forms of possession as well as potential futures, defining this shadow as peace is continually deferred.

RESUMEN

Los intentos por terminar el largo conflicto armado en Colombia incluyen grandes esfuerzos por parte del Estado colombiano orientados a producir una nueva época: el “posconflicto”. La restitución de tierras, una política que aspira devolver y titular tierras a los que las perdieron por causa del conflicto, fue promovida precisamente como parte de dicho esfuerzo hacia la paz. A partir de trabajo etnográfico en la región del Urabá exploro como, en la sombra del posconflicto, la restitución de tierras ha traído consigo diversas formas de especulación en torno a regímenes jurídicos, económicos y de violencia. En este contexto, la posesión especulativa de tierras simultáneamente invoca formas históricas de posesión así como futuros posibles, definiendo la sombra del posconflicto mientras la paz continuamente se difiere.
Aktorzy, relacje i sieci – o współpracy naukowej nie bibliometrycznie
Authors: Czerniawska Dominika , Fenrich Wojciech , Bojanowski Michał
Published: March 2020

Współpraca w nauce jest względnie dobrze opisywana na poziomie makro dzięki ilościowym analizom dużych baz bibliograficznych. Takie ujęcie współpracy naukowej ma jednak szereg znanych ograniczeń. Stoimy na stanowisku, że, aby poszerzyć wiedzę o procesach społecznych w świecie nauki, konieczne jest bardziej pogłębione ujęcie, które (1) rozróżnia różne typy aktorów społecznych identyfikowanych przez naukowców jako potencjalni współpracownicy, (2) identyfikuje cechy relacji współpracy, które potencjalni współpracownicy postrzegają jako istotne, (3) jakimi strukturami sieci relacji współpracy otoczeni są naukowcy i jakie czynniki odpowiadają za zróżnicowanie tych struktur. Za pomocą 30 wywiadów pogłębionych (IDI) przeprowadzonych z polskimi naukowcami zebraliśmy szczegółowe informacje na temat poszczególnych współpracy, które pozwoliły nam na analizę relacji z indywidualnych perspektyw i rozrysowanie ego-centrycznych sieci współpracy poszczególnych respondentów. Wśród swoich współpracowników naukowcy wymieniają zarówno osoby, jak i zespoły lub całe instytucje. Rozróżniają również współprace symetryczne i niesymetryczne. Struktury ego-centrycznych sieci współpracy są zróżnicowane ze względu na (a) strategie przywódcze kierowników zespołów, szczególnie pod względem tego, czy zespoły są budowane wokół ludzi, czy też raczej wokół pozycji; (b) ulokowanie instytucjonalne poprzez łatwość bądź trudność nawiązywania współpracy z naukowcami z większych ośrodków; (c) stopień naukowy i zmiany w zasadach finansowania, albowiem grant badawczy dla „młodego naukowca” pozwala mu na więcej swobody i oderwanie od lokalnych hierarchii organizacyjnych.
Citizen sociolinguists scaling back
Authors: Rymes Betsy , Smail Gareth
Published: March 2020

This paper examines the different ways that professional experts and everyday language users engage in scaling practices to claim authority when they talk about multilingual practices and the social significance they assign to them. Specifically, we compare sociolinguists’ use of the term translanguaging to describe multilingual and multimodal practices to the diverse observations of amateur online commentators, or citizen sociolinguists. Our analysis focuses on commentary on cross-linguistic communicative practices in Wales, or “things Welsh people say.” We ultimately argue that by calling practices “translanguaging” and defaulting to scaled-up interpretations of multilingual communication, sociolinguists are increasingly missing out on analyses of how the social meaning of (cross)linguistic practices accrues and evolves within specific communities over time. By contrast, the fine-grained perceptions of “citizen sociolinguists” as they discuss their own communicative practices in context may have something unique and underexamined to offer us as researchers of communicative diversity.

Pediatricians’ knowledge, attitudes and practices surrounding menstruation and feminine products
Authors: Singer Miriam R. , Sood Nikita , Rapoport Eli , Gim Haelynn , Adesman Andrew , Milanaik Ruth
Published: March 2020

Objective

This study investigates whether primary care pediatricians adhere to the American Academy of Pediatrics (AAP) recommendations by routinely evaluating patients’ menstrual cycles and educating patients about menstruation and feminine products. Additionally, this study examines pediatricians’ knowledge and attitudes surrounding menstrual health topics.

Methods

A 53-item online questionnaire was developed to evaluate pediatricians’ knowledge, attitudes and clinical practices regarding menstruation-related topics. The questionnaire was emailed to 2500 AAP members using a geographically-stratified sampling approach, with pediatricians in each state selected randomly. Mann-Whitney U tests, t-tests, and logistic regressions were used to assess associations between correlates and pediatricians’ knowledge, attitudes and practices.

Results

Five hundred and eighteen out of 2500 pediatricians participated (response rate = 20.7%), 462 met inclusion criteria; 78.8% were female, 79.2% were Caucasian. The majority of the pediatricians (58.2%) were “not at all” or only “slightly” familiar with the AAP guidelines on anticipatory guidance surrounding menarche. Many reported they do not routinely provide anticipatory guidance regarding menstruation to pre-menarchal patients (24.7%), discuss menstruation with post-menarchal patients (33.1%) or ask patients the date of their last period (28.4%). The majority were unlikely to discuss feminine products with patients. Gaps in menstruation-related knowledge were noted. Male pediatricians were significantly less likely to evaluate patients’ menstrual cycles and provide patient-education regarding menstruation-related topics, and had significantly lower self-rated and measured knowledge of these topics.

Conclusions

A concerning number of pediatricians in a national sample do not abide by AAP recommendations surrounding menstruation and exhibit knowledge gaps in this area. To effectively address the health needs of female patients, pediatricians should better incorporate menstrual health care into their clinical practice.
Research on Power Generation Control of Asynchronous Machine as Main Generator
Authors: Sun Yannan , Hu Jisheng , Li Changxian
Published: March 2020

High-power asynchronous machine can be used as the main generator of diesel locomotive and marine power system. The standalone power system of asynchronous generator based on four-quadrant converter is proposed. The magnetic field energy required by the machine must meet the minimum requirements for power generation, and the balance between power generation and load power must be ensured. Therefore, the initial voltage and capacitance of the DC-link capacitor are first analyzed and calculated. After that, the simple and easy slip prediction control is designed, that is, the given electric frequency takes into account the influence of the slip ratio. A power generation system is designed with an asynchronous machine as the main generator to achieve a DC voltage of 750 V, with an output power of up to 520 kW. Simulate the system for different operating conditions. The stable DC voltage is maintained under full load at different speeds. When suddenly unloading or loading 50 %, it can restore stable DC voltage in 10 ms time. In the case of stepless speed regulation and stepped speed regulation of diesel engine, the generator can still generate a stable DC voltage with loads of different power levels. The simulation results show that the power generation system has good load capacity and good dynamic performance.
Democratic Legitimacy and the Competence Obligation
Authors: Malcolm Finlay
Published: March 2020

What obligations are there on voters? This paper argues that voters should make their electoral decision competently, and does so by developing on a recent proposal for democratic legitimacy. It then explores three problems arising from this ‘competency obligation’. First, how should voters be competent? I propose three conditions required for voter competence. Second, how competent should voters be? I argue that the competency required tracks the significance of the consequences of the vote. Third, if the electorate are unlikely to deliver a competent decision, should suffrage be restricted to the competent alone? I defend unrestricted suffrage on the grounds that restricting suffrage cannot guarantee a competently made electoral decision. Instead, obligations on voters should be minimised by political parties satisfying their obligations to be politically sound; if they are sound, then the obligation to be competent can be easily satisfied by voters.

The rapid advancement of perovskite-based optoelectronics devices has caught the world’s attention due to their outstanding properties, such as long carrier lifetime, low defect trap density, large absorption coefficient, narrow linewidth and high optical gain. Herein, the photonic lasing properties of perovskites are reviewed since the first stimulated emission of perovskites observed in 2014. The review is mainly focused on 3D structures based on their inherently active microcavities and externally passive microcavities of the perovskites. First, the fundamental properties in terms of crystal structure and optical characteristics of perovskites are reviewed. Then the perovskite lasers are classified into two sections based on the morphology features: the ability/inability to support lasing behaviors by themselves. Every section is further divided into two kinds of cavities according to the light reflection paths (Standing wave for the Fabry–Pérot cavity and travelling wave for the Whispering-Gallery-Mode cavity). The lasing performance involves fabrication methods, cavity sizes, thresholds, quality factors, pumping sources, etc. Finally, some challenges and prospects for perovskite lasers are given.
Flucht – Migration – Gender

Im vorliegenden Beitrag wird vor dem Hintergrund diskursiv verhandelter Topoi über Geflüchtete untersucht, inwiefern Sportlehrkräfte geflüchtete Schüler*innen als ‚Andere‘ wahrnehmen. Angesichts der binären Geschlechterordnung, die sowohl im Sport als auch im Diskurs um Geflüchtete reproduziert wird, liegt der Schwerpunkt hierbei auf der geschlechterbezogenen Konstruktion von ‚Anderssein‘. Dafür werden der Forschungsstand und konstruktivistische und postkoloniale Theoriebezüge skizziert sowie 31 Interviews mit Sportlehrkräften unter einem diskursanalytischen Fokus ausgewertet. Die Befunde legen nahe, dass der Umgang mit geflüchteten Schüler*innen mit dem Normalitätsverständnis der Interviewten und der Institution Schule bricht. Darüber hinaus lassen sich fluchtbezogene Konstruktionsmuster erkennen, die durch die Körperzentrierung des Sportunterrichts besonders aktualisiert und von den Befragten geschlechtstypisierend und kulturell ausgedeutet werden.

Bartolomei, S, Nigro, F, Malagoli Lanzoni, I, Masina, F, Di Michele, R, and Hoffman, JR. A comparison between total body and split routine resistance training programs in trained men. J Strength Cond Res 35(6): 1520–1526, 2021—The purpose of the present investigation was to compare the effects of total body (TB) versus split routine (SR) resistance training workouts on maximal strength and muscle hypertrophy in trained men. Twenty-one resistance-trained men were randomly assigned to either a TB (TB: age = 24.1 ± 4.4 years; body mass = 78.7 ± 11.3 kg; body height = 177.0 ± 3.9 cm) or the SR group (SR: age = 24.9 ± 4.2 years; body mass = 79.2 ± 9.5 kg; body height = 175.2 ± 6.0 cm). Both groups performed a 10-week resistance training program. Isokinetic bench press at 75 and 25 cm·s−1 (ISOK75 and ISOK25, respectively), isometric bench press (ISOBP), isometric squat (ISOSQ), and one repetition maximum BP and SQ assessments were performed before and after training. Muscle thickness of the pectoralis major (PECMT), superior part of trapezius (TRAPMT), and vastus lateralis (VLMT) muscles was also evaluated at the same timepoints using ultrasonography. Improvements were observed in both groups for all strength assessments and muscle thicknesses. Only changes in ISOK25 were significantly (p = 0.015) greater in TB than in SR, while significantly greater (p = 0.037) changes in VLMT were detected in SR compared with TB. Results indicated that a TB training paradigm may be more appropriate for maximal strength improvement, while an SR training protocol may be more optimal in stimulating muscle growth in experienced, resistance-trained men.
Gray Areas

“Navigable narratives” are a subgenre of narrative-based video games under the umbrella definition of “walking simulators.” While they are a subgenre of video games, analyzing their score or soundscape purely through a video game lens paints an incomplete picture because of their different artistic focus. Models like Elizabeth Medina-Gray's modular analysis are a useful start but insufficient on their own to understand this genre's sound. Rather, a participant's experience in a navigable narrative is often quite similar to that of a soundwalk, especially a virtual reality soundwalk; the game composer/audio designer creates an intricate soundscape through which the participant moves, and with the main focus on the story and gradual travel, the participant has more time and capacity than in a typical video game to build meaning from the soundwalk they perform. One of the major relationships navigable narratives have with soundwalks is the breakdown of diegesis in the soundscape the participant takes in, which is unlike most video games. To analyze the soundwalk and also the soundscape present in navigable narratives, I draw from R. Murray Schafer, Hildegard Westerkamp, and Janet Cardiff. In the opposite direction, in many ways navigable narratives are very much like “literary computer games,” or interactive narratives that may be analyzed via “ludostylistics” à la Janet Murray and Astrid Ensslin. A key element in many navigable narratives is the use of narrative time, as described by Alicyn Warren, rather than real time, which also sets navigable narratives apart from standard video games and especially from soundwalks. To explore these varied models and lenses, I demonstrate an analytical approach, using Leaving Lyndow (2017) as my primary case study. And so, between these analytical lenses of video game music theory, soundscape and soundwalk study, and ludostylistics applicable to literary computer games, I posit that the sound of navigable narratives is best understood through a synthesis of all three.
Canon Anxiety?
Authors: Cook Karen M.
Published: March 2020

Canons—of music, video games, or people—can provide a shared pool of resources for scholars, practitioners, and fans; but the formation of canons can also lead to an obscuring or devaluing of materials and people outside of a canon. The four authors in this colloquy interrogate issues of canons relating to video game music and sound from a variety of perspectives. Each author considers an aspect of canonization and argues for a wider purview. In “Rewritable Memory: Concerts, Canons, and Game Music History,” William Gibbons examines the ways in which concerts of video game music may create canons and reinforce particular historical narratives. In “On Canons as Music and Muse,” Julianne Grasso views the music originally presented in a video game as itself a type of canon and argues that official and fan arrangements of original game music may provide windows into lived experiences of play. In “The Difficult, Uncomfortable, and Imperative Conversations Needed in Game Music and Sound Studies,” Hyeonjin Park highlights issues of diversity and representation in the field of video game music and sound studies, with respect to the people and music that make up the subjects of the field, the people who produce scholarship in the field, and the people who engage with game music and sound. In “Canon Anxiety?” Karen Cook pulls together various issues of academic canons to question the scope, focus, and diversity of the growing field in which the Journal of Sound and Music in Games exists.

The 15th anniversary of the SIEC test under the EU Merger Regulation – where do we stand? (Part 1)
Authors: Kuhn Tilman
Published: March 2020

On May 1, 2019, the significant impediment to effective competition (“SIEC”) test pursuant to Article 2(2) and (3) of the EU Merger Regulation (Regulation No. 139/2004; “EUMR”), celebrated its 15th anniversary. The Commission has taken more than 5,000 decisions in merger cases under this new standard in the last decade and a half. Therefore, it seems opportune to pause and take stock. Has the introduction of the SIEC test achieved the desired results? Has it been applied according to the legislator’s plans? Does its application need to change going forward?

After a short recap of the test’s history and genesis (I.) and a reminder of the burden and standard of proof (II.), this article reviews the Commission’s decisional practice (and the limited practice of the EU Courts) systematically, and intends to summarize the various theories of harm covered by the SIEC test’s application in practice (III.). Second, it analyzes the decisional practice and draws conclusions as to whether the test’s application in practice is predictable, persuasive, and in line with the legislator’s intent (IV.). Third and last, after some practical and procedural observations (V.), it concludes with a few proposals for improvement (VI.).

Given the scope of the ground covered, this article is split into two separate parts over two separate volumes of this journal, with Part 1 in this volume covering sections I. and II., as well as part III. with regard to horizontal mergers and a brief summary in this respect. Part 2 of the article will then continue section III. with non-horizontal mergers, and finish with sections IV. through VI.
Zur Interpretation empirischer Evidenz vor Gericht
Authors: Bönisch Peter , Inderst Roman
Published: March 2020

Bei der Verwendung der empirischen Evidenz in ökonomischen Gutachten ergeben sich mitunter gravierende Fehlinterpretationen. So wird mangelnde statistische Signifikanz zuweilen als Evidenz für die Abwesenheit jeglichen Effekts interpretiert oder die statistische Widerlegung eines Nulleffekts als Beleg für eine bestimmte Verstoßeffektshöhe angeführt. Um solchen Fehlinterpretationen vorzubeugen, stellt dieser Aufsatz zunächst die in der gutachterlichen Praxis verwendeten statistischen Konzepte (der Signifikanzniveaus, p-Werte, t-Tests und Konfidenzintervalle) als Variationen des stets gleichen Testverfahrens dar. Sieht man die Ergebnisse aus dieser Perspektive, werden auch die engen Grenzen einer Interpretation offensichtlich und die häufigen Fehlinterpretationen verständlich. Der Aufsatz geht allerdings darüber hinaus und stellt mit dem Konzept der „Severity“ (Schwere der Evidenz) ein einfaches zusätzliches Instrumentarium vor, mit dem die vorhandene Evidenz anschaulich dargestellt werden kann, um damit insbesondere verschiedene mögliche Verstoßeffekte auf ihre Kompatibilität mit der vorhandenen Evidenz hin zu prüfen.
