Prior real-world experience influences non-linguistic statistical learning
Authors: Van Hedger Stephen Charles , Johnsrude Ingrid , Batterink Laura
Published: June 2020

Listeners are adept at extracting regularities from the environment, a process known as statistical learning (SL). SL has been generally assumed to be a form of “context-free” learning that occurs independently of prior knowledge, and SL experiments typically involve exposing participants to presumed novel regularities, such as repeating nonsense words. However, recent work has called this assumption into question, demonstrating that learners’ previous language experience can considerably influence SL performance. In the present experiment, we tested whether previous knowledge also shapes SL in a non-linguistic domain, using a paradigm that involves extracting regularities over tone sequences. Participants learned novel tone sequences, which consisted of pitch intervals not typically found in Western music. For one group of participants, the tone sequences used artificial, computerized instrument sounds. For the other group, the same tone sequences used familiar instrument sounds (piano or violin). Knowledge of the statistical regularities was assessed using both trained sounds (measuring specific learning) and sounds that differed in pitch range and/or instrument (measuring transfer learning). In a follow-up experiment, two additional testing sessions were administered to gauge retention of learning (one day and approximately one-week post-training). Compared to artificial instruments, training on sequences played by familiar instruments resulted in reduced correlations among test items, reflecting more idiosyncratic performance. Across all three testing sessions, learning of novel regularities presented with familiar instruments was worse compared to unfamiliar instruments, suggesting that prior exposure to music produced by familiar instruments interfered with new sequence learning. Overall, these results demonstrate that real-world experience influences SL in a non-linguistic domain, supporting the view that SL involves the continuous updating of existing representations, rather than the establishment of entirely novel ones.

America’s Most Divided Sport: Polarization and Inequality in Attitudes about Youth Football
Authors: Lindner Andrew Micah , Hawkins Daniel N.
Published: June 2020

Football may be America’s most popular sport, but, with growing evidence of the risk of sport-associated concussions, some adults are reconsidering which sports they would encourage children to play. Using data from a nationally representative sample of 958 respondents, we examine how political party, belief in patriotic displays in sport, attention to concussion news, social class, and race are associated with encouragement of children playing each of the five major U.S. sports: baseball, basketball, hockey, soccer, and football. Our findings suggest that unlike other sports, attitudes about youth participation in football are divided by views on patriotism in sport, age, race, education, and attention to concussion news. For many Americans, football is connected to participation in a civil religion, which celebrates national pride and respect for the military. We argue that child safety advocates who aim to steer children away from football must grapple with the deeper cultural and identity-based framework associated with the sport.
Wyrok Trybunału Sprawiedliwości w sprawie National Grid Indus BV – złote runo czy puszka Pandory?
Authors: Prejs Ewa
Published: June 2020

This paper examines the decision of the European Court of Justice in the National Grid Indus case issued on 29 November 2011, concerning exit tax levied on unrealised capital gains relating to the assets of a company transferring its place of management for tax purposes between Member States. The author indicates the significance of the judgment. She generally shares the ECJ’s opinion but argues that justifications based on the need to safeguard the allocation of taxing rights among Member States should not be rejected by the ECJ without any differentiation regarding specific circumstances. The author also considers whether the ECJ changed its view on the provisions introduced by the member states in their domestic law relating to remedies safeguarding the recovery of the tax, such as interest payments and bank guarantees, and mandatory provisions allowing for future decreases in value of the company assets transferred to another Member State.
Obywatelstwo i obywatelskość w Unii Europejskiej
Authors: Poboży Monika
Published: June 2020

Celebration of the 20th anniversary of the EU citizenship in 2013 was a good occasion for reflection on this institution. Has anything changed during this period in the status of European citizens and their role in the EU’s political system? Do they have opportunities to participate in the European decision-making process and to influence the European law and the direction of the EU’s development? Is the EU citizenship only a symbolic project that brings no added value? Can it be called “citizenship”? The article is devoted to answering these questions. The institution of the EU citizenship was analysed in two aspects: 1) citizenship as formal status connected with some rights and 2) civilness as mechanisms that guarantee participation in decisions on the future of a political community. The conclusion is that after 20 years the importance of the EU citizenship has been significantly increased, but only on declarative level – in the wording of treaties and institutional acts. However, this change has not caused the factual increase of citizen participation in the shaping of the European Union politics. It is the effect of a discrepancy on the EU level between citizenship as formal status and civilness as real empowerment of individual in the political system.
Instytucjonalne reprezentacje głównych wyznań religijnych w Unii Europejskiej
Authors: Kołsut-Markowska Anita
Published: June 2020

The institutional and organisational presence of the main religions in Europe is diverse. Representatives of Christianity, Islam or Judaism hold different status in their relations with the EU structures. The forms, range and dynamics of their actions vary as well. The position of Christianity in the discussions over the various issues of European policies is strengthened by the preponderance of Christianity in Europe, its proven and efficient organisational structures within the European Union, as well as the support granted to the Catholic Church by the Holy See.
Wspólnotowy wymiar polityki imigracyjnej Unii Europejskiej w obliczu wyzwań związanych ze zwiększonym napływem imigrantów w 2015 r.
Authors: Skorzycki Michał
Published: June 2020

The article comprises the overview of the essential legal, administrative and financial means that the EU has at its disposal in case of rapid influx of immigrants, as well as a selection of major obstacles to the use of these tools, based on observation of the activities of the EU and its member states taken up to deal with the aforementioned situation which took place in 2015. Using the abovementioned observation and an analysis of relevant documents, it is argued that the refugee crisis of 2015 has revealed the necessity of a profound institutionalisation of the European immigration policy as the most effective way to overcome difficulties in response to such situations. The analysis leads also to the conclusion that the EU is caught in a dilemma of either suspending the Dublin system in crisis situations or creating a new system of intensive support for border member states.
Nowe procedury konsultacji Komisji Europejskiej jako czynnik niwelujący deficyt demokracji w UE
Authors: Vetulani-Cęgiel Agnieszka
Published: June 2020

The objective of the article is to assess the new Commission’s Guidelines on Stakeholder Consultation (2015) in the EU policy-shaping in view of raising effectiveness of the EU governance model and of reducing the EU democratic deficit. The hypothesis of the article is that the Commission’s revision of the stakeholder consultation procedures contributes to overcoming the EU crisis of the consultation model and, in general, to reducing the democratic deficit in the EU. The neoinstitutional research perspective permits to catch the relations between the EU institutions and stakeholders wanting to co-shape EU sectoral policies, and the concepts of the UE democratic legitimacy (by F. Scharpf) as well as of the deliberative democracy (by J. Habermas) make possible to verify the research hypothesis. The verification takes place also in the course of the analysis of the new guidelines by confronting them with the identified deficits in matters of the dialogue with stakeholders.
Transformation Towards a Market Oriented Economy – an Impetus or Hindrance for Organized Crime in Poland?
Authors: Buszko Andrzej
Published: June 2020

This article deals with the phenomenon of organized crime that has emerged as an urgent and serious problem in Poland during the transformation period. The solid background for organized crime group activity was created during the communist time. Due to the strong position of the police (that time called militia), and the security body, organized crime was not so well developed. After 1989, the organized crime groups (OCG) started to be more active, both in the domestic and the international market. The patterns of organized crime group activity were presented. So the main objective of the paper is to reveal the evolution of OCG activities and their scale in Poland. The organized crime groups have proven to be skillful in the exploitation of legal loopholes. The OCG became less violent, and focused more on economic crimes.
The Efficiency of Sovereign Debt Markets in the EMU: Truth or Mistruth?
Authors: Waszkiewicz Grzegorz
Published: June 2020

Ever since the last financial crisis, the efficiency of financial markets has been widely challenged. On the basis of sovereign debt markets in the European Monetary Union (EMU), we tried to contrast some reservations about the market efficiency existing in the literature with findings coming from our empirical analysis of weak-form efficiency. To do so, we first outlined the crux of the efficient market hypothesis. Secondly, we show the main reservations in relation to this concept. Then, after a brief review of outcomes from contributions in this area, we conducted a three-stage empirical procedure that Worthington and Higgs (2006) as well as Borges (2009) had employed to stock markets analysis. Then, the results were evaluated and conclusions were drawn. To sum up, we did confirm the weak-form efficiency on examined sovereign debt markets from the EMU. That suggests that a random process plays a key role in shaping bond yields. Finally, neither theoretical nor practical reservations deflate the weak-form efficiency in the public debt markets of the EMU.
Structure and Constituents of Digital Marketing Systems
Authors: Robul Yuriy
Published: June 2020

The article addresses the study of digital marketing as a marketing system, the definition of its key elements, feeds and outputs, as well as levels of structure. At the moment, digital marketing is mostly considered at the micro level, while it is functioning at the level of the entire economy, and the systemic interaction between digital marketing and other social subsystems are not well understood. The result of the study is the conceptualization of the digital marketing model as a marketing system and the allocation of three levels of digital marketing. This opens up prospects for a better understanding of the processes of economic development, factors of influence and means to manage.
Publicly Funded Abortion and Marginalised People’s Experiences in Catalunya
Authors: Ostrach Bayla
Published: June 2020

Abortion law reforms enacted in Spain in 2010 and extended to Catalunya expanded access to abortion. Simultaneously, the autonomous region was affected by economic crisis and austerity, affecting access to care for migrant and marginalised populations. Mixed-method ethnographic data were collected in relation to low-income and immigrant women seeking abortion in two phases: (1) 2012–2013 and (2) early 2016. Data sources included surveys, interviews and participant observation. Data analysis combined descriptive statistics, modified Grounded Theory, thematic analysis and constant comparative methods. Despite public funding of care in a system ostensibly available to all, marginalised people seeking abortion reported reduced access and more barriers to access. Participant experiences with legal, publicly funded abortion revealed bureaucratic difficulties and delays as well as inconsistent and inadequate information. Data on marginalised people’s experiences demonstrate that even where abortion is legal and ostensibly available, politico-economic contexts and trends affect their access to abortion and public health care.
Reflective Practitioners and Participant Observers in Autism Services
Authors: Long Joseph J.
Published: June 2020

Situated practice research offers rich possibilities for recognising and developing practitioner knowledge in social care. In this article, I document the application of anthropological methods and thinking within a research programme in autism services. Drawing on Donald Schön’s model of the reflective practitioner, I argue that participant observation, aimed at the holistic documentation of autism services, provides a means to systematic reflection, comparison and learning in order to inform practice. This approach stands to broaden the field of autism research from unidirectional models of knowledge ‘translation’ to include research and insights generated from services. I also advocate the relational nature of anthropology as a means to meaningfully engage autistic people with intellectual disabilities in research through collaboration with practitioner researchers.
Anthropology from Home
Authors: Góralska Magdalena
Published: June 2020

The coronavirus pandemic has made ethnographic fieldwork, as traditionally conceived in anthropology, temporarily impossible to conduct. Facing long-term limitations to mobility and physical contact, which will challenge our research practices for the foreseeable future, social anthropology has to adjust to these new circumstances. This article discusses and reflects on what digital ethnography can off er to researchers across the world, providing critical insight into the method and offering advice to beginners in the field. Last, but not least, the article introduces the phrase ‘anthropology from home’ to talk about research in the pandemic times – that is, geographically restricted but digitally enabled.

Published: June 2020

İkinci Dünya Savaşı'nda Sovyetler Birliği radyo yayınlarında Almanya'ya karşı propaganda amaçlı şarkılar yayınlamıştı. Bunlar içerisinde Vasiliy Lebedev tarafından yazılan ve Sovyetler Birliği'nin ulusal marşının bestecisi Aleksandr Aleksandrov tarafından bestelenen "Kutsal Savaş" isimli şarkı radyo yayınlarında ön plana çıkarılmış ve Sovyet halkının Alman ordularına karşı mücadelesini teşvik etmek için propaganda amaçlı kullanılmıştı. Çalışma kapsamında "Kutsal Savaş" adlı şarkı özelinde İkinci Dünya Savaşı'nda Sovyetler Birliği'nin radyo yayınlarında Almanya'ya yönelik propaganda amaçlı hangi söylemlere yer verildiğinin ortaya çıkarılması amaçlanmıştır. Bu amaçla çalışmada "Kutsal Savaş" adlı şarkının sözleri, dilbilimci Roman Jakobson'un göstergebilim metodu ışığında analiz edilmiştir. Marşın müziksel analizi duyumsal olarak gerçekleştirilmiştir. Marşın iki bölmeli şarkı formunda la minör tonunda farklı çalgı gruplarından enstrumanlar eşliğinde icra edildiği gözlemlenmiştir. Elde edilen bulgularda, propaganda şarkısında doğrudan Almanya'ya yönelik nefret söyleminin inşa edildiği ve ideolojik söylemler üzerinden Almanya'nın Sovyetler Birliği için tehlikeye yol açtığı vurgulanarak, Alman ordularına karşı Sovyet halkının seferber edilmeye çalışıldığı ortaya konulmuştur.

Witold Szalonek’in (1927-2001) Quattro Monologhi Adlı Solo Obua Eserinin İcra Bakımından İncelenmesi Ve Uygulama Önerilerinde Bulunulması başlıklı bu çalışma, Yeni Müzik solo obua repertuvarının önemli bir eserini tanıtarak, icra etmek isteyen obuacıları bilgilendirmek ve uğraşlarını kolaylaştırmak amacını taşımaktadır. Yenilikçi bir besteci olan Witold Szalonek’in, çoksesli tınılar tekniğini Bruno Bartolozzi’nin (1911-1980) New Sounds for Woodwind adlı ünlü çalışmasından önce kullandığı bilinmektedir. 1966 yılında bestelediği Quattro Monologhi eserinde, dönemin simgesel öneme sahip çoksesli tınılar ve kurbağa dili yeni çalış tekniklerinin yanı sıra, çok az bilinen sadece kamışla çalma tekniğini de değerlendirmektedir. Szalonek’in kullandığı rastlamsal yazı, ilkesel olarak “hem icracıyı kontrol altında tutmak hem de ona serbestlikler tanıyarak müzikal fantezisini olabildiğince özgürleştirmek” amacını güdmüştür. Bu çalışmada, yüksek icra kalitesine ulaşabilmek amacıyla eserin ayrıntılı icra analizi yapılmıştır. Ulaşılan sonuca göre; yeni çalış tekniklerinin icrasında başarılı olabilmek için icracı, kullandığı çalgı modelini ve kamış özelliklerini irdelemeli, sabırlı ve bilinçli çalışmalardan sonucunda edineceği kişisel tecrübeyle yardımcı teknikler üzerinde ustalaşarak kendinde has bir duyarlılık geliştirmelidir. Bu tekniklerin kullanımındaki ayar, başarının anahtarı olacaktır. Belli bir beceriye ulaşıldıktan sonra, önce “eserin notasyonunun öğrenilmesi, sonrasında ise çalış tekniklerinin bireysel olarak çalışılmasıyla istenilen müzikal ifadenin eserde uygulanması” tavsiye edilmektedir. Yapılan çalışma, icra analizi ve yazarın kendi tecrübelerine dayanarak uygulama önerilerinde bulunmasıyla icra bakımından kolaylıklar sağlamaktadır.

stoljeća ta je grafija učestala u selima Borke (od 1685.), Stanetinski Breg (od
1688.) i Stanetinec (od 1690.). Sela Borke, Stanetinec Breg, Stanetinec i

godine 1900. (Prhovec, Globoka). S druge strane, grafem ß (scharfes S),
zabilježen početkom 19. stoljeća, posljedica je pisanja prezimena austrijskog
državljanina. Zbog
jednokratnog bilježenja nije isključeno da su neke grafije rezultat pogrešnog

Бұл жұмыста тұрақты динамикалық пішіні және массасы өзгермелі үш осьті бейстационар дененің Ньютондық центрлік гравитациялық өрісіндегі ілгерілмелі-айналмалы қозғалысы зерттелді. Координаттар басы сфералық дене центрінде жататын салыстырмалы координата жүйесіндегі үш осьті бейстационар дененің ілгерілмелі-айналмалы қозғалысы қарастырылған. Бірінші дене сфералық-симметриялы массасы бар шар болып табылады, оның таралу массасы және радиусы мен негізгі центрлік инерция моменттері уақытқа тәуелді функциялар болып табылады. Екінші дене - динамикалық құрылымы өзара перпендикуляр және массалар центрі арқылы өтетін үш жазықтыққа симметриялы, өзгермелі массалы дене. Екінші дененің бас инерция моменттері және үш ось бойындағы сығылу коэффициенттері әртүрлі, уақытқа тәуелді функциялар болып табылады. Екінші дененің динамикалық формасы үш осьті. Оның бас инерция моменттері әртүрлі жылдамдықпен өзгереді және де сығылу коэффициенттері де әртүрлі мәнге ие. Екінші денемен қатаң байланысқан өзіндік координата осьтері өзара перпендикуляр үш симметрия жазықтығының қиылысуынан туындайтын осьпен бағытталады. Екінші дене массасы және өлшемдері өзгеруіне байланысты туындайтын реактивті күштер нөлге тең емес, оның модулі мен бағыты өзгермелі. Екінші денеге реактивті күштер мен массалар геометриясының өзгеруінен туындайтын қосымша айналмалы моменттер әсер етеді. Бейстационар үш осьті дене эволюция барысында өзара перпендикуляр үш жазықтыққа байланысты әрқашанда симметриялы болады. Осы өзара перпендикуляр үш жазықтық қиылысу түзулері оның бас инерция осьтерін анықтайды. Өзіндік координаттар жүйесінің осьтері дененің бас инерция осьтері бойымен бағытталған және эволюция барысында бағдары өзгеріссіз қалады деп қабылдаймыз. Үш осьті бейстационар дененің массасы мен өлшемі өзгеру салдарынан туындайтын реактивті күштер мен моменттер денеге әсер етеді, және олар нөлге тең емес. Салыстырмалы координата жүйесінде үш осьті бейстационар дененің ілгерілмелі-айналмалы қозғалысының дифференциалдық теңдеулері алынды.
СУБЛИМАЦИЯ ПЫЛЕВЫХ ЧАСТИЦ ВБЛИЗИ БЕЛОГО КАРЛИКА G29-38

Published: June 2020

Проведены расчеты температурного баланса и орбитальной эволюции силикатных и графитовых пылевых частиц в области сублимации около белого карлика G29-38. Темп сублимации (испарения) задается температурой нагрева пылевых частиц в зависимости от расстояния до звезды, параметров материала и радиусов пылинок в пределах от 0.01 до 100 мкм. Учитывалось влияние давления радиации и эффекта торможения Пойнтинга-Робертсона на динамику пыли. В расчётах предполагается, что частицы срываются с родительских тел, движущихся по круговым орбитам. Наши расчёты показали, что гранулы могут образовать резкую границу области сублимации на определённом расстоянии от звезды в зависимости от материала частиц. Если около звезды с параметрами, близкими к G29-38, преобладают силикатные частицы, то внутренняя граница зоны сублимации для крупных гранул радиусами s > 5 мкм образуется на расстоянии около 45 Rstar ≈ 0.6Rsun. Малые силикатные частицы радиусами s < 0.1 мкм не могут приблизиться к звезде на расстояние ближе 300Rstar ≈ 4Rsun из-за быстрого испарения. Если преобладают графитнокарбоновые частицы, то граница зоны сублимации для частиц радиусами s > 0.2 мкм возможна на расстоянии около 12.5 Rstar ≈ 0.16 Rsun. Карбоновые частицы радиусами s < 0.1 мкм испаряются за пределами расстояния 0.6Rsun. Если согласно Rearch (2009) температура пыли Т = 950К, то наблюдаемая часть пылевого облака (диска) соответствует расстоянию от звезды около 1Rsun, где могут существовать только крупные силикатные частицы радиусами s > 5 мкм или карбоновые радиусами s > 0.5 мкм.

Evaluación de políticas públicas con métodos cuasi-experimentales: una aplicación a las políticas activas de empleo en la Comunidad Valenciana
Authors: Vila José , Gómez Yolanda , Martínez Juan , Cervera-Ferri José Luis
Published: June 2020

Este artículo presenta un estudio comparativo de dos metodologías de medición de impacto de políticas públicas: los métodos baseline y cuasi-experimental. Ambos métodos son aplicados a la evaluación de las políticas activas de empleo implementadas en la Comunidad Valenciana en el periodo 2012-2015. La aplicación de ambos métodos a un mismo conjunto de políticas permite cuantificar un fenómeno (habitualmente citado en la literatura, pero escasamente validado empíricamente) como es el grado de confusión entre los efectos de una política y los de la evolución de su entorno, asociados a la utilización del método baseline. Los resultados de este análisis muestran que, en algunos casos, más de dos terceras partes del impacto medido a través de indicadores baseline es en realidad atribuible a variaciones del entorno y no a la política evaluada. Como consecuencia, los resultados de este artículo muestran los peligros de afrontar la evaluación de políticas desde un enfoque baseline y la conveniencia de recurrir a métodos alternativos con base experimental.
Economic Models of Optimism: What Does the Evidence Say?
Authors: Caballero Adrián , López-Pérez Raúl
Published: June 2020

Recent economic models define a (non-Bayesian) optimist as someone whose beliefs and expectations are typically “too rosy”, in the sense that her priors and the evidence objectively available statistically warrant a more negative outlook. This paper reviews the existing empirical literature on optimism to assess the empirical relevance of those models. While there exists abundant and compelling evidence in favor of motivated inference, i.e., that preferences shape beliefs, the support for the most specific predictions of the economic models seems mixed, if not negative. We discuss open questions and opportunities for future research
Sobornos y contratación pública: un experimento económico
Authors: Vargas Villamizar Álvaro Javier , Palacio García Luis Alejandro
Published: June 2020

La presente investigación pretende determinar si el pliego de condiciones genera incentivos para la entrega de sobornos en la contratación pública. En este sentido, el objetivo es analizar cómo la discrecionalidad del Burócrata y las asimetrías de información afectan el nivel de entrega de sobornos y la discriminación de concursantes en una subasta para la adjudicación de contratos públicos. Para ello se realizó un experimento económico de laboratorio, cuyo diseño experimental simuló una subasta por contratos públicos bajo cuatro tratamientos. Se encontró que las asimetrías de información son una herramienta útil para disminuir la entrega de sobornos y que existe discriminación negativa por parte del Burócrata al asignar los contratos. Por lo cual, se logra concluir que el poder que posee el Burócrata para decidir sobre el ingreso de los participantes a la subasta es el principal detonante para la entrega de sobornos
