Published: June 2020

The optical properties are investigated by spectroscopic characterizations for bilayer InGaAs/GaAs quantum dot (QD) structures consisting of a layer of surface quantum dots (SQDs) separated from a layer of buried quantum dots (BQDs) by different GaAs spacers with thicknesses of 7 nm, 10.5 nm and 70 nm. The coupling from the BQDs to SQDs leads to carrier transfer for the two samples with thin spacers, 7 nm and 10.5 nm, in which QD pairs are obtained while not for the 70 nm spacer sample. The carrier tunneling time is measured to be 0.145 ns and 0.275 ns from BQDs to SQD through the 7 nm and 10.5 nm spacers, respectively. A weak emission band can be observed at the wavelength of ∼ 960 nm, while the excitation intensity dependent PL and PLE spectra show that this is from the wetting layer (WL) of the SQDs. This WL is very important for carrier dynamics in bilayer structures of BQDs and SQDs, including for carrier generation, capture, relaxation, tunneling, and recombination. These results provide useful information for understanding the optical properties of InGaAs SQDs and for using such hybrid structures as building blocks for surface sensing devices.
Strip-pair comparison method for building threshold color-difference model: theoretical model validation
Authors: Brusola Fernando , Tortajada Ignacio , Lengua Ismael , Jordá Begoña , Peris-Fajarnés Guillermo
Published: June 2020

This paper presents a method for developing color-difference models near a threshold, based on the serial exploration method described by Torgerson [Theory and Methods of Scaling(Wiley,1958), chap. 7], involving the construction of color-control strips of patches arranged in arrays of 2 × n, where n is the number of pairs in the strip. The patches in the lower row should be calorimetrically identical, while the color of the patches in the upper row should vary progressively in constant steps of CIELAB color difference along selected color space vector directions. Prospective observers are instructed to indicate the patch pair number for which they begin to perceive a slight color difference between corresponding patches. The frequency data obtained from the observers was used to build a threshold color-difference model. The intention was to validate the method with theoretical data to determine the effect of the precision with which the strips are constructed, on the accuracy of the estimated parameters. Theoretical frequency data was generated using the CIE94 color difference formula, whose associated color discrimination ellipsoid parameters are very easy to determine, associated with a hypothetical logistic psychometric curve for different color centers. The proposed method allows to determine color discrimination parameters with a precision nearby 4% and an accuracy of 3% with respect to the simulated theoretical parameters, for color samples generated with a standard deviation ofΔEab∗=0.2of the superimposed error around the ideal color difference of pairs of patches.

Published: June 2020

In this paper, AlInN nanowire ultraviolet light-emitting diodes (LEDs) with emission at ∼299 nm have been successfully demonstrated. We have further studied the light extraction properties of these nanowire LEDs using photonic crystal structures with square and hexagonal lattices of nanowires. The light extraction efficiency (LEE) of the periodic nanowire LED arrays was found to be significantly increased as compared to random nanowire LEDs. The LEEs reach ∼ 56%, and ∼ 63% for the square and hexagonal photonic crystal-based nanowire structures, respectively. Moreover, highly transverse-magnetic polarized emission was observed with dominant vertical light emission for the AlInN nanowire ultraviolet LEDs.
Low-loss hyperbolic dispersion and anisotropic plasmonic excitation in nodal-line semimetallic yttrium nitride
Authors: Gao Han , Sun Lei , Zhao Mingwen
Published: June 2020

Hyperbolic isofrequency of materials (referred to as hyperbolic materials) renders an unusual electromagnetic response and has potential applications, such as all-angle negative refraction, sub-diffraction imaging and nano-sensing. Compared with artificially structured hyperbolic metamaterials, natural hyperbolic materials have many obvious advantages. However, present natural hyperbolic materials are facing the limitations of narrow operating frequency intervals and high loss stemming from electron-hole excitations. Using first-principles calculations, we demonstrated that the recently-discovered nodal-line semimetallic yttrium nitride (YN) can be tuned to a type-I natural hyperbolic material with a broad frequency window from near-IR (∼1.4 μm) to the visible regime (∼769 nm) along with ultra-low energy loss, owning to the unique electronic band structure near the Fermi level. The unusual optical properties of YN, such as all-angle negative refraction and anisotropic light propagation were verified. The tunable hyperbolic dispersion can be interpreted in terms of the linear relation between critical frequency and plasma frequency. A branch of plasmon dispersion with strong anisotropy in the low-energy region was also revealed in the electron-doped YN. This work is expected to offer a promising strategy for exploring high-performance hyperbolic materials and regulating plasmon properties.
Polarization-insensitive, omnidirectional fiber-optic ultrasonic sensor with quadrature demodulation
Authors: Liu Guigen , Zhu Yupeng , Sheng Qiwen , Han Ming
Published: June 2020

We report an ultrasonic sensor system based on a low-finesse Fabry–Perot interferometer (FPI) formed by two weak chirped fiber Bragg gratings (CFBGs) on a coiled single-mode fiber. The sensor system has several desirable features for practical applications in detecting ultrasound on a solid surface. By controlling the birefringence of the fiber coil during the sensor fabrication, the sensor is made insensitive to the polarization variations of the laser source. The circular symmetric structure of the fiber coil also renders the omnidirectional response of the sensor to ultrasound. While the fiber coil is bonded directly to the structure, the CFBGs are suspended from the structure and free from large background strains with little reduction to the sensitivity of the sensor. The low-finesse FPI features a sinusoidal reflection spectrum. Like the conventional phase-generated carried technique, a phase modulator is utilized to implement quadrature demodulation. Therefore, the sensing system is adaptive to large background perturbations experienced by the fiber coil.
Impact of carrier transport on the performance of QD lasers on silicon: a drift-diffusion approach
Authors: Saldutti Marco , Tibaldi Alberto , Cappelluti Federica , Gioannini Mariangela
Published: June 2020

The operation of quantum dot lasers epitaxially grown on silicon is investigated through a quantum-corrected Poisson-drift-diffusion model. This in-house developed simulation framework completes the traditional rate equation approach, which models the intersubband transitions involved into simultaneous ground-state and excited-state lasing, with a physics-based description of carrier transport and electrostatic effects. The code is applied to look into some of the most relevant mechanisms affecting the lasing operation. We analyze the impact of threading dislocations on non-radiative recombination and laser threshold current. We demonstrate that asymmetric carrier transport in the barrier explains the ground-state power quenching above the excited-state lasing threshold. Finally, we study p-type modulation doping and its benefits/contraindications. The observation of an optimum doping level, minimizing the ground-state lasing threshold current, stems from the reduction of the electron density, which counteracts the benefits from the expected increase of the hole density. This reduction is due to electrostatic effects hindering electron injection.
The omnivore at home and abroad: The value to the state of food tourism discourse of diversity
Authors: Duffy Andrew , Pang Annabel
Published: June 2020

While a discourse of difference has routinely been used as a marker of national identity, such an approach is premised on exclusion. By contrast, this article considers how inclusion or diversity may be employed in nation-building discourse, and its impact on the citizenry, as embodied in the omnivore – one who appreciates a wide range of cultural artefacts and, in doing so, evokes a high status. Using a Verstehen approach to critical discourse analysis, we analyse one kind of state media – the Singapore Tourism Board’s food-related webpages – to assess how they represent citizens and tourists as culinary omnivores, and how this may be interpreted to reveal mechanisms of hegemonic state control.
Naga youth engagement with Korean popular culture: An alternative avenue
Authors: Yimchunger Jasmine
Published: June 2020

Based on ethnographic research in Nagaland, a north-eastern state in India, this article critically examines the engagement of Naga youth with Korean media focusing on its popularity, meaning-creation and negotiation, against the larger context of Indo-Naga political issues. Naga youth, denied time and space by the Indian mainstream media, have found in Korean media an alternative way to engage themselves. It also examines the complex process of reception of Korean media by the Nagas to re-negotiate the broader terrains of modernity, identity and national culture. The reception process also illuminates the political tensions between the centre and periphery and reflects the political status and identity of the Naga vis-à-vis the mainstream Indian identity. The tension between Naga nationalistic sentiments and de-indianization comes out in this transnational media engagement. And as they carve out an identity in this complex matrix from the local across the global, it is an expanded identity that is highly mediated with remnants of the memories of past injustices and struggles, an identity that goes beyond the borders of Nagaland.

Aspectos atmosféricos y climáticos en la expansión de la pandemia (COVID-19) en la provincia de Alicante
Authors: Olcina Cantos Jorge , Biener Camacho Samuel , Martí Talavera Javier
Published: June 2020

La pandemia de la COVID-19 se ha convertido en uno de los mayores desafíos recientes que se ha encontrado la ciencia. Multitud de estudios pretenden dar respuesta a la propagación de este coronavirus, hasta ahora desconocido, ante unas condiciones atmosféricas y climáticas determinadas. El estudio de parámetros como la temperatura, la humedad y la radiación en los meses de febrero y marzo de 2020, así como un análisis correlativo con otras variables de distinta temática, pretende ponderar el peso que pudieron haber tenido estas variables en la expansión de este patógeno en la provincia de Alicante. Los resultados obtenidos apuntan, de forma preliminar, como la única variable que guarda relación con la tasa de contagio y la tasa de defunción son las temperaturas máximas. Este hecho podría estar relacionado con el nicho climático del coronavirus, el cual podría ser determinante en su expansión a nivel mundial. La carencia de información sobre las anteriores tasas a nivel municipal, así como la inexistencia de datos de movilidad a tan baja escala, impide establecer unas conclusiones definitorias.
Revitalization of Islamic Boarding School Management to Foster the Spirit of Islamic Moderation in Indonesia
Authors: Fathurrochman Irwan , Ristianti Dina Hajja , Arif Mohamad Aziz Shah bin Mohamed
Published: June 2020

Islamic moderation-based boarding school management is vital to be carried out amidst the negative stigma of radicalism. This study aims to analyze the management revitalization of Islamic boarding schools conducted by Islamic boarding schools in Bengkulu, Indonesia, i.e., Miftahul Jannah, Hidayatullah, Ar-Rahmah, Muhammadiyah, and Al-Hijaaz Islamic boarding schools, in order to foster a spirit of Islamic moderation in Indonesia. This study used a qualitative method. The researchers were actively involved in managerial activities in Islamic boarding schools as a part of uncovering phenomena that occur in Islamic boarding schools. The results showed that the revitalization of boarding school management in order to have a significant role in preventing radicalism was done by creating commitment and not giving the slightest opportunity to the emergence of radicalism, returning the position of the existence of boarding schools as tafaqquh fiddin and boarding school managers committed to not engage in practical politics, to monitor strictly all boarding school programs to be free from radicalism. The spirit of Islamic moderation is used as a foothold in the practice of religious life so that Islamic boarding schools become a driving force in fostering the spirit of Islamic moderation.
Strategic Planning Model of Islamic Religious Higher Education (PTKI) in Indonesia
Authors: Agus Zaenul Fitri  , Nasukah Binti , Tayeb Azmil
Published: June 2020

Strategic planning for higher education is vital because it becomes a reference in determining the direction of policy and organizational performance. To win the competition in gaining the market, strategic planning activities become the spearhead in determining the strategy to achieve the appropriate institutional goals. However, the implementation of strategic planning at Islamic Religious Higher Education (PTKI) is often constrained because of the lack of understanding of the importance of these theories, so the implementation of strategic planning is often only intended for administrative requirements. Amid this condition, there is a phenomenon where some PTKIs are developing rapidly and transforming to be more market-oriented and to win the competition. These PTKIs are UIN Maulana Malik Ibrahim Malang, UIN Syarif Hidayatullah, IAIN Tulungagung, Muhammadiyah University of Malang, and Malang Islamic University. They have succeeded in creating effective strategies in organizational development until now they can become modern institutions and develop into multi-level organizations. The purpose of this study is to explore the five PTKI strategy models in Indonesia at the corporate and business unit levels based on Fred R. David's corporate-level strategy models, and Porter's generic strategy model theory Data were collected by qualitative methods through observation, interview, and documentation techniques. The results showed that at the corporate level, Fred R. David's strategy models applied by PTKI were vertical integration strategy, intensive strategy, and diversification strategy. In the defensive strategy, what is more, applied is the retrenchment strategy choice. However, at the business unit level, Porter's well-implemented strategy models are the cost leadership strategy, differentiation strategy, and focus strategy. These results have implications for the selection of business strategy models to be used in either profit-oriented or non-profit strategic planning activities in PTKI.
Gamification in nursing

Published: June 2020

Introduction: With new generations of students entering the educational system and calling for novel adult learning approaches, such as gamification, traditional didactics seem to be diminishing in importance. The aim of this paper is to introduce gamification as a novel concept in adult learning and to present its impact on nursing education.Methods: Through a combination of 2dSearch, Publish or Perish and PubMed2XL applications and the set criteria, we used the Google Scholar and Medline / PubMed search engines to compile, analyse, and synthesise studies related to gamification in correlation with the educational process in the field of nursing. To assess the level of methodological quality of research, we used the Mixed Methods Appraisal Tool (MMAT).Results: The final analysis included nine studies related to gamification in nursing course units. Most often, game elements in the form of badges and feedback were included. Most research studies reported a positive impact of gamification on nursing students in the form of increased motivation and engagement, with only one survey reporting a negative impact in the form of inappropriateness and inefficiency. The evaluation of the included studies according to the MMAT tool showed a medium level of methodological quality. Discussion and conclusion: Gamification is a relatively new concept in nursing education and represents the potential for a more advanced way of conveying information. In the future, research should be carried out to clarify the concept of gamification and examine the possibilities of its implementation in the educational environment in Slovenia.

Interestingly, anion and cation of 2 both contain the Tp* ligand. Moreover, the cationic moiety highlights an unusual sodium atom hexacoordinated by six DMSO molecules acting as O-bonded ligands. Three of which exhibit a bridging coordination mode and three are in terminal position. To the best of our knowledge, the framework of [Na2Tp*(μ-Me2SO)3(Me2SO)3] is unprecedented.

Authors: Szreder Jarosław , Walentynowicz Piotr
Published: June 2020

The article attempts to identify, classify and evaluate the success factors of development projects implemented in the holiday property sector. The first part of the study presents development prospects for this market in Poland. The next part presents the idea of using key success factors in management. The empirical part presents the results of own research and the conclusions resulting therefrom. The analyses were based on the experience gained during the successful implementation of this type of projects and the opinions of their clients. The information presented in the literature on the subject was also helpful in developing the KCS list for the examined sector. In the authors’ opinion, despite conducting the research in an unrepresentative manner, the resulting conclusions, which are qualitative, can be highly helpful in implementing such projects in practice and as a material for discussion in the process of educating students.
Time-Varying Housing Market Fluctuations: Evidence from the U.S. Housing Market
Authors: Ozdemir Dicle
Published: June 2020

The objective of this paper is to investigate how the housing market and credit market factors contribute to US business and interest rate cycles in a time-varying transition probability modeling framework. The Markov switching results appear to exhibit periods of low-growth regime and highgrowth regime for both house and credit markets. The study also shows that the transition probabilities reflecting the regime switching behavior of business and interest rate cycles vary over time as functions of the house and credit market. We find that both the housing market and credit market contribute to whether the economy remains in a high-growth regime or moves into lowgrowth regime, and whether the interest rates remain in a low or high-growth regime. The results show that the housing market plays a leading role in affecting the time-varying probabilities between regimes for the business and interest rate cycles.
Mobile learning in a flipped classroom: findings from a “5-lecture-5” blended learning design for large classes
Authors: Yilmaz Yusuf , Suner Aslı , Yilmaz Ozlem
Published: June 2020

Objective

We aimed to develop and evaluate a mobile learning (m-learning) design for large group application learning based on flipped classroom approach within an integrated curriculum of medical faculty.

Materials and methods

Totally 359 students enrolled in a two-credit course during the 2017–2018 academic year. An instructional design called 5-Lecture-5 (5L5) was implemented via mobile application. This design is a blend of m-learning and flipped classroom approaches, with pre-, during-, and post-lecture elements. Data were analysed using Chi-square, Mann–Whitney U, and Kruskal–Wallis tests. Open-ended questions and course observations were analysed thematically and reported together.

Results

Of the participating students, 26.96% who saw the first announcement examined pre-lecture materials and 55.43% attended face-to-face lecture. Achievement test scores of those who attended lecture were significantly higher (p = 0.027). Correct response rates for each question were 99.30, 72.10, 58.70, and 94.40%, respectively. Consequently, students demonstrated positive attitude towards m-learning (M = 170.15 ± 28.48). The most preferred positive aspects were “active learning,” “interactive,” “entertaining,” “useful,” and “repeatable.”

Conclusions

M-learning activities within a flipped classroom with instant feedback were found to increase participation and interaction levels of students in classroom setting, resulting in their increased enjoyment and engagement.
Egypt’s Quest for Social Justice
Authors: Mansour Rasha S.
Published: June 2020

This paper examines Egypt’s shift from socialism to neo-liberalism in the wake of the economic crisis of the late 1980s and the implications of this shift for its socialist legacy. It argues that the decline of the welfare state in Egypt since 1991 has contributed to the erosion of the social contract forged in the post-independence period, which was marked by state-led development and high social mobility and a prominent role for the middle class. Neoliberal ‘reforms’ dictated by economic crisis and pressures from transnational capital as well international financial institutions led to the alienation of the middle and lower classes and the emergence of a new economic elite, whose dubious links to the ruling class has undermined the regime’s legitimacy and helped fuel the 25 January 2011 uprising.
Why Syria Considers Israel an Existential Threat
Authors: Wakim Jamal
Published: June 2020

This article argues that Syria considers Israel as an existential threat and that peace or coexistence between the two sides is impossible in the long run, due to the fact that Syria’s perception of its own history and identity, as an entity that consists of a majority belonging to one ethnicity, (90 percent Arabs), and various religious groups, is in direct conflict with Israel’s perception of its own history (80 percent Jews from various ethnicities). This renders Syrian national security in direct conflict with Israel’s perception of its national security. In addition, both sides are competing over the same sphere of influence which is Greater Syria. This has rendered any reconciliation impossible between the two sides and has led to a continuous struggle with the failure of all efforts to establish peace and end the conflict between them.
Joint Speech
Authors: Day-O’Connell Jeremy
Published: June 2020

In charting the “territory between speech and song,” Cummins (2020) identifies various forms of vocal behavior involving “multiple people uttering the same thing at the same time”—what the author calls “joint speech.” I interrogate this conceptual framework in light of specific examples both musical and linguistic, which suggest a usefully expanded category: “collaborative vocality.” At the same time, I also propose a distinctly musical account of joint speech that ultimately affirms the conventional separation between music and language. Central to this account is an analysis of the unique character of singing and an insistence on the centrality of pleasure in musical experience.
Think twice: a rare calcium sensing receptor mutation and a new diagnosis of familial hypocalciuric hypercalcaemia
Authors: Tellam Jane J , Abdulrasool Ghusoon , Ciin Louise C H
Published: June 2020

Distinguishing primary hyperparathyroidism (PHPT) from familial hypocalciuric hypercalcaemia (FHH) can be challenging. Currently, 24-h urinary calcium is used to differentiate between the two conditions in vitamin D replete patients, with urinary calcium creatinine clearance ratio (UCCR) <0.01 suggestive of FHH and >0.02 supportive of PHPT. A 26-year-old Caucasian gentleman presented with recurrent mild hypercalcaemia and inappropriately normal parathyroid hormone (PTH) following previous parathyroidectomy 3 years prior. He had symptoms of fatigue and light-headedness. He did not have any other symptoms of hypercalcaemia. His previous evaluation appeared to be consistent with PHPT as evidenced by hypercalcaemia with inappropriately normal PTH and UCCR of 0.0118 (borderline low using guidelines of >0.01 consistent with PHPT). He underwent parathyroidectomy and three parathyroid glands were removed. His calcium briefly normalised after surgery, but rose again to pre-surgery levels within 3 months. Subsequently, he presented to our centre and repeated investigations showed 24-h urinary calcium of 4.6 mmol/day and UCCR of 0.0081 which prompted assessment for FHH. His calcium-sensing receptor (CASR) gene was sequenced and a rare inactivating variant was detected. This variant was described once previously in the literature. His mother was also confirmed to have mild hypercalcaemia with hypocalciuria and, on further enquiry, had the same CASR variant. The CASR variant was classified as likely pathogenic and is consistent with the diagnosis of FHH. This case highlights the challenges in differentiating FHH from PHPT. Accurate diagnosis is vital to prevent unnecessary surgical intervention in the FHH population and is not always straightforward.

Learning points:

Distinguishing FHH from PHPT with co-existing vitamin D deficiency is difficult as this can mimic FHH. Therefore, ensure patients are vitamin D replete prior to performing 24-h urinary calcium collection.

Individuals with borderline UCCR could have either FHH or PHPT. Consider performing CASR gene sequencing for UCCR between 0.01 and 0.02.

Parathyroid imaging is not required for making the diagnosis of PHPT. It is performed when surgery is considered after confirming the diagnosis of PHPT.
Enseñar y aprender a argumentar a lo largo de la escolaridad
Authors: Padilla Constanza
Published: June 2020

Desde hace varias décadas, diferentes campos disciplinares abordan el estudio de la argumentación, desde diversos enfoques, los cuales -más allá de sus divergencias-, contribuyen a configurar un mapa de los complejos aspectos implicados en esta temática, que exige un tratamiento interdisciplinario. El mayor problema radica en la escasa relación entre estos estudios teóricos y el ámbito educativo, o más bien en la “aplicación” de algunos enfoques (retóricos y/o lógicos), en detrimento de otros (dialógicos y dialécticos), que habilitan el planteamiento de su dimensión epistémica y colaborativa. Tanto estos enfoques, como otros que enfatizan la relevancia de las dimensiones actitudinal, emocional, ética y situada, son indispensables para entender la complejidad de la argumentación y de su posible enseñanza y aprendizaje. En este artículo, consideramos algunos de estos aportes teóricos y empíricos que contribuyen a analizar las condiciones de posibilidad de una enseñanza sistemática de la argumentación a lo largo de la escolaridad.
(Im)posibilidades de enseñanza de la argumentación en la escuela
Authors: Lopes Piris Eduardo
Published: June 2020

En Brasil, la enseñanza de argumentación en la educación primaria y secundaria es entendida como la enseñanza de ensayo argumentativo, pues tal práctica fue institucionalizada por un Decreto presidencial que determinó la exigencia de un ensayo en lengua portuguesa en los exámenes de ingreso a la educación superior. Discuto las condiciones que favorezcan a la escuela a enseñar a sus educandos a argumentar, a tomar la palabra en la esfera pública para presentar, justificar, sostener, rechazar y (re)evaluar argumentos en situaciones de conflicto de perspectivas sobre una cuestión argumentativa. Presento una propuesta de enseñanza de la argumentación en situación concreta de interacción con orientaciones para desarrollar las capacidades y competencias argumentativas en el marco de la educación emancipatoria del ser humano, con el fines de superar el modelo de capacitación para redacción de ensayo argumentativo, una práctica de legitimación del régimen de exclusión en el sistema educativo brasileño.

Resulta innegable ignorar la brecha que separa las prácticas de lectura y escritura que tienen lugar en el nivel secundario y las que son necesarias en la universidad para acceder al conocimiento disciplinar y a la construcción de conocimiento científico. La toma de conciencia de esta situación de desventaja con la que llegan los estudiantes al primer año universitario ha llevado a implementar acciones tendientes a abordar la escritura en las aulas universitarias. En este sentido, el objetivo de este trabajo es dar cuenta de cómo se puede ayudar a los ingresantes universitarios a escribir un texto argumentativo de especialidad a partir de las retroalimentaciones escritas dadas por un docente de una materia de primer año de Humanidades de una universidad pública a un grupo de estudiantes que participan en ciclos de investigación-acción mediante el empleo de comentarios escritos digitales.
ЗОВНІШНЯ ТОРГІВЛЯ ПОСЛУГАМИ У КОНТЕКСТІ ПОСТІНДУСТРІАЛЬНОГО РОЗВИТКУ УКРАЇНИ
Authors: МЕЛЬНИК Тетяна
Published: June 2020

Досліджено тенденції розвитку зовнішньої торгівлі послугами України в період переходу до постіндустріального суспільства. Частка експорту українських послуг у 2017 р. становила 0,2% світового експорту і 0,1% світового імпорту.Проаналізовано зовнішню торгівлю технологічно місткими послугами за критерієм наукомісткості, за яким Євростат виокремлює 4 групи високотехнологічних послуг: вищого рівня наукомісткості; наукомісткі ринкові послуги; наукомісткі фінансові послуги; інші наукомісткі послуги. У зовнішній торгівлі частка високотехнологічних послуг становить 42%, з яких 26% припадає на експорт. Отже, Україна є нетто-експортером на світовому ринку високотехнологічних послуг і має понад 1,6 млрд. дол. додатного сальдо.Освітні послуги, які належать до четвертої групи наукомістких послуг, характеризуються конкурентними перевагами. В Україні високий коефіцієнт покриття населення вищою освітою. Кінцеві споживчі витрати домашніх господарств на освіту у 2016 р. становили 1,3% усіх витрат у фактичних цінах. Незважаючи на те, що цінова політика українських ВНЗ достатньо лояльна, з кожним роком збільшується кількість студентів, які виїжджають на навчання за кордон. За даними центру CEDOS, кількість українських студентів, що навчаються в іноземних університетах, у 2016/17 навчальному році становила 72 тис. осіб. Згідно з даними Державної міграційної служби України, у 2016 р. виїхали за кордон 13621 особа, а повернулися лише 1958 осіб. Причому виїжджають висококваліфіковані фахівці, що негативно впливає на якість освіти. У міжнародних рейтингах університетів українські ВНЗ посідають місця у другій половині списку, причому у кількості 5,6 з 289.Дослідження рівня загальних витрат на душу населення за паритетом купівельної спроможності на охорону здоров’я виявило, що в Україні він нижчий порівняно зі світовим в 1,8 раза, а з країнами пострадянського простору – у 2–3,1 раза. Витрати держави та населення на охорону здоров’я зростають (у 2017 р. вони становили 0,02% ВВП), проте не супроводжуються підвищенням якості послуг. За программами особистого медичного страхування звертаються не більше 6% українців. Отже, необхідно розробити нормативно-правовы стандарти у сфері послуг, гармонізованих з міжнародними стандартами.

Досвід глобального розвитку останніх десятиліть дозволяє виявити два взаємопов’язаних, але разом з тим різних напрями трансформацій, які безпосередньо фокусуються у площині цієї проблематики. На початку XXI ст. глобальна економіка вступила у нову еру розвитку, оскільки стрімко загострилися суперечності між транснаціональним виміром капіталу та державним суверенітетом як формою організації та функціонування суспільства. Глибинним наслідком глобалізації є обмеження регулюючих функцій держав. При цьому держави вже не можуть належним чином захистити національні економіки від дисбалансів та асиметричних шоків. Унаслідок лібералізації національні уряди втрачають можливість дієвого використання цілої низки макроекономічних інструментів.Місце і роль держави за умов сучасних трансформацій визначається перш за все тим, що держава розглядається як суб’єкт, який забезпечує організацію та функціонування всіх елементів соціально-економічної системи. Виступаючи представником суспільства в цілому, саме держава встановлює правила функціонування та ринкової взаємодії економічних агентів у межах певного господарського порядку і здійснює контроль за їх дотриманням. Підґрунтям для реалізації виваженої економічної політики має слугувати наукова ідентифікація стратегічних пріоритетів розвитку економіки й визначення на цій основі концептуальних підходів та інструментарію з метою гармонізації інтересів суспільства.

Well-being and inequality in comparative perspective: the case of Poland and Ukraine
Authors: Kovalisko Natalia , Makeev Serhii
Published: June 2020

Socio-economic trajectories of Poland and Ukraine have been considerably diverging since the last decade of the 20th century. The former has been advancing and catching up with Western European countries in terms of the quality of life — whereas in Ukraine, the 1990s recession gave way to unsustainable economic growth, which interrupted in the second half of the 2000s and in the 2010s. The comparison of official statistics, along with the data of household surveys and public opinion polls, makes it possible to conclude that a progressive and sustainable transition from a command economy to free market, as exemplified by Poland, is accompanied by moderate deepening of economic inequality. However, an abnormal transition (deviating from the “Polish rule”) entails excessive concentration of wealth and gives rise to corruption as a mechanism of income redistribution among different categories of population. This also results in a more noticeable stratification of opportunies for meeting vital and existential needs. Owing to a large proportion of shadow economy and undeclared work, Ukrainians remain a source of cheap labour in both the domestic and international labour markets; in addition, a persistent subculture of tax evasion is being formed in this country.

Background and aims

The Conceptual Framework of Harmful Gambling moves beyond a symptoms-based view of harm and addresses a broad set of factors related to the risks and effects of gambling harmfully at the individual, family, and community levels. Coauthored by international research experts and informed by multiple stakeholders, Gambling Research Exchange (GREO) facilitated the framework development in 2013 and retains responsibility for regular updates and mobilization. This review article presents information about the revised version of the Conceptual Framework of Harmful Gambling completed in late 2018.

Methods

We describe eight interrelated factors depicted in the framework that represent major themes in gambling ranging from the specific (gambling environment, exposure, gambling types, and treatment resources) to the general (cultural, social, psychological, and biological influences). After outlining the framework development and collaborative process, we highlight new topics for the recent update that reflect changes in the gambling landscape and prominent discourses in the scientific community. Some of these topics include social and economic impacts of gambling, and a new model of understanding gambling related harm.

Discussion and conclusions

We address the relevance of the CFHG to the gambling and behavioral addictions research community. Harm-based frameworks have been undertaken in other areas of addiction that can both inform and be informed by a model dedicated to harmful gambling. Further, the framework brings a multi-disciplinary perspective to bear on antecedents and factors that co-occur with harmful gambling.
Crooked Prophets, Ungodly Politicians and their Publics
Authors: Wyk Ilana van
Published: June 2020

Pentecostal Charismatic Christianity (PCC) has had a radical and public impact on African cities, believers and politics. Scholars often describe this impact in terms of the “Pentecostalization” of the public sphere. Looking at Prophet Bushiri and his Enlightened Christian Gathering Church in South Africa, I argue that the ontological situatedness of PCC believers, “unbelievers” and those who shared a spirited world view led to a plurality of public spheres and counter publics. Thus, secular commentators in South Africa did not understand the Pentecostal message or its expression while locals who believed in a spirited world interpreted Prophet Bushiri’s messages and behaviour in terms that dismissed debate in favour of (violent) action. Within PCC circles, which often stretched beyond the local to encompass vast networks of “spiritual kin”, communicative flows were scuppered by an unstable public moved by the Spirit rather than secular political processes.
Contradicción, antinomia y el problema de una introducción a la filosofía en el pensamiento hegeliano entre 1797 y 1802
Authors: Mattana-Ereño Leonardo
Published: June 2020

La intención del este artículo es presentar algunas pautas fundamentales del pensamiento hegeliano en el periodo indicado, con respecto a la relación entre lógica y metafísica y el problema de una introducción a la filosofía. A través de algunos textos de los años entre 1797 y 1802, podemos observar la evolución de dos conceptos clave como la contradicción y la antinomia y sus implicaciones para el incipiente pensar sistemático de Hegel.
Las relaciones entre teoría y práctica en la obra de Ortega y su conexión con la filosofía de la técnica orteguiana
Authors: Alonso Marcos
Published: June 2020

El presente artículo realiza un recorrido a las complejas y cambiantes concepciones de Ortega y Gasset sobre teoría y práctica. Tras unos primeros años en los que la teoría aparece en una posición preponderante respecto de la práctica, en un segundo momento, a partir de la madurez orteguiana de los años 30 —y en especial después de su detenido tratamiento del problema de la técnica— la dimensión práctica pasará a ocupar este primer lugar. Defenderemos que la propuesta de Ortega de entender la realidad radical como quehacer supone un intento de superación de este problema.

Shallow landslides through land degrading not only lead to threat the properly and life of human but they also may produce huge ecosystem damages. The aim of this study was to compare the performance of two decision tree machine learning algorithms including classification and regression tree (CART) and reduced error pruning tree (REPTree) for shallow landslide susceptibility mapping in Bijar, Kurdistan province, Iran. We first used 20 conditioning factors and then they were tested by information gain ratio (IGR) technique to select the most important ones. We then constructed a geodatabase based on the selected factors along with a total of 111 landslide locations with a ratio of 80/20 (for calibration/validation). The performance of the models was checked by the true positive rate (TP Rate), false positive rate (FP Rate), precision, recall, F1-Measure, Kappa, mean absolute error, and area under the receiver operatic curve (AUC). Results of IGR specified that the slope angle and TWI had the most contribution to shallow landslide occurrence in the study area. Moreover, results concluded that although these models had a high goodness-of-fit and prediction accuracy, the CART model (AUC=0.856) outperformed the REPTree model (AUC=0.837). Therefore, the CART model can be used as a promising tool and also as a base classifier to hybrid with optimization algorithms and Meta classifiers for spatial prediction of shallow landslide-prone areas.

Tutor-demonstrated feedback in the mini-clinical evaluation exercise
Authors: Bhattarai Madhur , McAleer Sean
Published: June 2020

This article was migrated. The article was marked as recommended. Introduction: The mini-clinical evaluation exercise (mini-CEX) allows for assessment and subsequent feedback across a range of individual clinical cases, although much of what is assessed is left implicit. After the performance by a trainee, further observation of appropriate clinical performance by the tutor provides a strong standard of reference for effective learning. Methods: In each mini-CEX encounter one final year resident clinically assessed an unfamiliar patient in the presence of peers and a tutor. The tutor then demonstrated the appropriate clinical behaviour. Twelve peers rated the performance of the resident before and after the tutor-demonstrated feedback (TDF). The encounters with the first cases by each of the participants were completed one by one and the cycles of encounters with the next cases by each resident were similarly continued. Results: All 13 participants completed six mini-CEX encounters over one year with an overall response rate of 95% for peer-assessment ratings (PARs). There was a total of 1772 PAR forms each with seven parameters and 1772 peer-satisfaction rating (PSR). Reliability coefficients of PARs ranged from .77 to .93. The PARs decreased significantly in each of the six cases after TDF (p<0.001). Peers rated the performance more negatively after the TDF than before the TDF. The mean PSRs, however, increased significantly in each of the six cases after the TDF (p<0.05). The mean observation time of participants' performance decreased from 26 minutes in the initial two cases to 14.5 in the last two (p<0.001). Conclusion: The feasibility and the positive educational impact of the TDF were shown in our exploratory study. The novel concept of TDF in the mini-CEX as supervised learning events and formative assessment deserves further investigation.
