Koexistenzfiguren. Zu zwei Texten von Werner Picht und Ernst Simon aus dem Zweiten Jahr der Kreatur
Authors: Erdle Birgit R.
Published: December 2019

Der Aufsatz beschäftigt sich mit zwei Beiträgen zum zweiten Jahrgang der Zeitschrift “Die Kreatur“ (1927/1928) von Ernst Simon und Werner Picht – mit Pichts „Internationale Verständigung“ und Ernst Simons „Das Werturteil im Geschichtsunterricht“. Wie wäre deren Verhältnis zueinander zu beschreiben – als Dialog? Als Koexistenz? Oder als Aneinandervorbeirede? Im Hintergrund steht dabei die methodische Frage, wieviel Wissen über Kontext und Textgeschichte wir benötigen, um die Zeitschrift “Die Kreatur“ als Projekt und ihre Diskurse in ihrem Interagieren, ihrem intellektuellen Austausch oder ihrer Koexistenz lesen und verstehen zu können.
Real-time dynamics of soliton collision in a bound-state soliton fiber laser
Authors: Liang Hu , Zhao Xiaoming , Liu Bohan , Yu Jie , Liu Yange , He Ruijing , He Jiangyong , Li Hongye , Wang Zhi
Published: December 2019

We experimentally investigated the soliton collisions between soliton molecules and deuterogenic solitons spontaneously generated on the continuous wave (cw) noise background in an ultrafast erbium-doped fiber laser mode locked with MoS2 saturable absorber (SA). The dynamics of the soliton collisions were observed using the time-stretch dispersion Fourier transform technique. The noise-induced deuterogenic solitons first undergo spectral broadening and wavelength shifting, then collide successively with a soliton molecule and eventually vanish. Within the simple collision framework, the spectral-temporal dynamics of soliton collision would help to unveil the self-stabilization mechanism of the soliton molecules in consideration of dispersive wave shedding. This nonlinear dynamics is similar to the soliton rain, except that complex condensed soliton phase is substituted with a soliton molecule.

Two-dimensional material tungsten diselenide (WSe2) nanosheets are coated on a microfibre knot resonator (MKR) to achieve an all-optical power modulation functionality. On account of the strong absorption property of WSe2 and the resonance enhancement properties of MKR, the transmitted optical power of signal light within the WSe2-based MKR can be effectively modulated. The sensitivities of light–control–light experiments with 405- and 660-nm lasers are as high as 0.32 and 0.12 dB/mW, respectively. The sensitivities and power tuning can be enhanced by a higher resonance Q and a larger extinction ratio of MKR. In terms of the response time, the average rise and fall times are 3.5/3.7 and 3.5/4 ms with 405- and 660-nm lasers, respectively. This proposed structure is expected to achieve potential applications in all-fibre-optic–based tunable device such as optical modulator, detector, and so on.

Contested and Cemented Borders: Understanding the Implications of Overseas Indian Citizenship
Authors: Kumar-Banerjee Ananya
Published: December 2019

Although the Person of Indian Origin (PIO) and Overseas Citizen of India (OCI) schemes have existed for some time, they began to serve a political and economic purpose for the Republic of India with the arrival of the twenty-first century. The OCI status asserts “Indianness” as a legible quality in diasporic memory. It does the work of cementing political Indo-Pakistani and Indo-Bangladeshi borders, while coopting the language of transnationalism to bolster the fundamentally nationalist regime of capitalism at work in the Republic of India. The goal of this regime is to promote a functionally nationalist, and thus, anti-transnational reality. As more generations of South Asians live and grow up abroad, creating a legible “Indianness” functions as a service to the capitalist Indian economy. These individuals abroad are encouraged to identify as diasporic “Indians” who must engage with their “motherland.” Thus, the transnationalist discourse of decreasing territoriality is exploited by the Indian state to serve goals that function in ideological opposition to transnationalism. As this discourse of legible “Indianness” becomes more successful, there will be increasing incentives for the ruling party in India to further privilege OCIs. In the end, the language and capital of the OCIs affirms the powers of capitalism contemporary Indian nation-state.
In-situ X-ray techniques for non-noble electrocatalysts
Authors: Hung Sung-Fu
Published: December 2019

Electrocatalysis offers an alternative solution for the energy crisis because it lowers the activation energy of reaction to produce economic fuels more accessible. Non-noble electrocatalysts have shown their capabilities to practical catalytic applications as compared to noble ones, whose scarcity and high price limit the development. However, the puzzling catalytic processes in non-noble electrocatalysts hinder their advancement. In-situ techniques allow us to unveil the mystery of electrocatalysis and boost the catalytic performances. Recently, various in-situ X-ray techniques have been rapidly developed, so that the whole picture of electrocatalysis becomes clear and explicit. In this review, the in-situ X-ray techniques exploring the structural evolution and chemical-state variation during electrocatalysis are summarized for mainly oxygen evolution reaction (OER), hydrogen evolution reaction (HER), oxygen reduction reaction (ORR), and carbon dioxide reduction reaction (CO2RR). These approaches include X-ray Absorption Spectroscopy (XAS), X-ray diffraction (XRD), and X-ray Photoelectron Spectroscopy (XPS). The information seized from these in-situ X-ray techniques can effectively decipher the electrocatalysis and thus provide promising strategies for advancing the electrocatalysts. It is expected that this review could be conducive to understanding these in-situ X-ray approaches and, accordingly, the catalytic mechanism to better the electrocatalysis.
Effects of tension fatigue on the structure and properties of carbon black filled-SBR and SBR/TPI blends
Authors: Yang Liu , Liu Kaikai , Gu Zijun , Du Aihua
Published: December 2019

The aim of this study was to explore the impact of tension fatigue on the structure and properties of filled SBR and SBR/TPI blends. The effect of tension fatigue on the dynamic properties of carbon black-filled styrene-butadiene rubber (SBR) and SBR/trans-1,4-polyisoprene (SBR/TPI) blend vulcanizates were investigated by dynamic mechanical analysis (DMA). The Mooney-Rivlin analysis of tensile stress-strain data is used for the determination of a rubber network crosslink density. The fatigue fracture surface of SBR/TPI vulcanizates was observed with a scanning electron microscopy (SEM). The crystallinity of TPI in carbon black-filled SBR/TPI (80/20) was characterized by X-ray diffraction (XRD). The results showed that the incorporation of TPI into SBR vulcanizates influences the fatigue properties of the blend vulcanizates. The blend vulcanizates showed optimum fatigue properties with 20 phr TPI. With increasing fatigue cycles, the tensile properties and crosslink density of SBR vulcanizates were decreased substantially. Compared with that of SBR vulcanizates, the tensile properties and crosslink density of SBR/TPI (80/20) blend vulcanizates changed little with the increase in fatigue cycles, and tan δ and E′ decreased gradually with the fatigue cycles. There was a sharp decrease in the E′ and tan δ curve in the temperature range of 40 ~ 60°C. The XRD diffraction peak corresponding to 3.9 Å broadened when the fatigue cycles were increased to 1 million times, and a new peak with inter-planar spacing at 7.6 and 4.7 Å appeared.
Synergistic visible light photoredox catalysis
Authors: Zeitler Kirsten , Neumann Matthias
Published: December 2019

Within the last decade the combination of photoredox catalysis and other catalytic modes of activation has become a powerful tool for organic synthesis to enable transformations that are not possible using single catalyst systems and hence are complementary to traditional methodology. Especially reactions proceeding via synergistic catalysis where co-catalyst and photocatalyst simultaneously and separately activate different reaction partners greatly benefit from the special properties of molecules and transition metal complexes in their excited state being oxidizing and reducing in nature at the same time. Apart from allowing for the generation of radical (open-shell) reactive intermediates by SET under mild conditions from bench-stable, abundant precursors, the photocatalyst often acts to interweave the distinct catalytic cycles by interaction at multiple points of the reaction mechanism to provide overall redox-neutral processes by shuttling electrons within in this complex network of elementary reaction steps. Synergistic strategies moreover may allow to performing such reactions with enantioselectivity, while mostly the selectivity is achieved by the chiral co-catalyst. The merger of photocatalysis has been achieved with a broad range of alternative modes of catalysis including organocatalysis, Brønstedt and Lewis acid and base catalysis, enzyme catalysis as well as in the context of cross-coupling transition metal catalysis overcoming challenging steps in this methodology and therefore has contributed to considerably expand the repertoire of suitable coupling partners. While only selected examples will be discussed, this chapter will highlight various dual catalytic platforms focusing on the photocatalytically generated intermediates, but also illustrating the diverse roles of photocatalysts in the context of such synergistic multicatalysis reactions.
What do we currently know about the clinically isolated syndrome suggestive of multiple sclerosis? An update
Authors: Grzegorski Tomasz , Losy Jacek
Published: December 2019

Multiple sclerosis (MS) is a chronic, demyelinating, not fully understood disease of the central nervous system. The first demyelinating clinical episode is called clinically isolated syndrome (CIS) suggestive of MS. Although the most common manifestations of CIS are long tracts dysfunction and unilateral optic neuritis, it can also include isolated brainstem syndromes, cerebellar involvement, and polysymptomatic clinical image. Recently, the frequency of CIS diagnosis has decreased due to the more sensitive and less specific 2017 McDonald criteria compared with the revisions from 2010. Not all patients with CIS develop MS. The risk of conversion can be estimated based on many predictive factors including epidemiological, ethnical, clinical, biochemical, radiological, immunogenetic, and other markers. The management of CIS is nowadays widely discussed among clinicians and neuroscientists. To date, interferons, glatiramer acetate, teriflunomide, cladribine, and some other agents have been evaluated in randomized, placebo-controlled, double-blind studies relying on large groups of patients with the first demyelinating event. All of these drugs were shown to have beneficial effects in patients with CIS and might be used routinely in the future. The goal of this article is to explore the most relevant topics regarding CIS as well as to provide the most recent information in the field. The review presents CIS definition, classification, clinical image, predictive factors, and management. What is more, this is one of very few reviews summarizing the topic in the light of the 2017 McDonald criteria.
”Catastrophe is our Bedtime Story”: The Media-Fuelled Obsession with Death in Don Delillo’s Zero K
Authors: Baya Adina
Published: December 2019

Death and the mass-media represent two recurring and connected presences throughout Don DeLillo’s fiction. While his canonical novel White Noise is themed around the paradoxical link between the pathological fear of dying and consumerism, his latest novel Zero K is about the deferral of death through cryonics. Using the analytical tools of critical theory, the current paper aims to analyse how the portrayal of death appears in the media saturated and consumer-driven environment in which DeLillo’s characters evolve, and how technology contributes both to fuelling the obsession with dying and to feeding the illusion of immortality.
Anne Brontë’s Helen and her Atypical Insuborination: “A Will of her Own”
Authors: De Dios Torralbo Caballero Juan
Published: December 2019

This article examines the protagonist of The Tenant of Wildfell Hall (Helen Huntingdon/Graham) as an anomaly in the novelistic tradition. Helen Huntingdon is a character who decides for herself, without heeding the advice of her aunt and uncle (exercising “a will of her own”, “I take the liberty of judging for myself”). Helen Graham, in this manner, challenges society, the Victorian novel, and also the sentimental novel that preceded it. She suffers domestic violence at the hands of her husband and, in an extraordinary act of rebellion, courage and determination, abandons him, taking her son away with her. The author’s depiction of Helen’s spouse, the alcoholic and abusive Arthur Huntingdon, also constitutes a divergence from the status quo of the era, as affairs of this kind were not normally portrayed in novels about the affluent Victorian society.
History as Story and Parody in Julian Barnes’s the Noise of Time
Authors: Catană Elisabeta Simona
Published: December 2019

This article analyses Julian Barnes’s The Noise of Time, a postmodernist parody of the Russian communist world, and shows that historical truth is turned into a story which is remembered with bitter irony and which offers various interpretations. Being nothing but a story, history, associated with the symbol of noise, becomes subject to parody. Emphasizing the role of irony in revealing the dramatic effects of the Russian communist past, this essay remarks that parody functions as severe criticism.
Lives Fractured: Re/Naming and Identity in the Writing of Caryl Phillips
Authors: Čatić Emina , Öner I. Murat
Published: December 2019

The novels of Caryl Phillips often deal with the experiences and identities of those displaced and marginalized by society. Caryl Phillips is well known for employing different textual strategies such as spatiotemporal fragmentation, intertextuality, naming, and point of view shifts in order to portray the struggles and suffering of his characters. The aim of this article is to examine how Phillips uses naming of his characters to depict the effects exile, slavery and other forms of oppression may have on their lives and identities. In order to accomplish this, different characters from Phillips’s novels Cambridge (1991), The Nature of Blood (1997), Crossing the River (1993) and Higher Ground (1989) will be discussed. The analysis of the characters will draw upon three concepts of naming first proposed by Bénédicte Ledent (2002): anonymity, (re)naming and name alteration.
Homes on Borders in Chicano Literature
Authors: Tucan Gabriela
Published: December 2019

In “Borderlands/La Frontera” (1987), Gloria Anzaldúa writes about the “tradition of long walks” (11) across physical and imaginary borders, which defines her Mexican-American people. The borderland is both a space of transit and a state of transition from where the Chicanos venture into unknown territories. Their identity is constructed around and across space(s). In this paper, I seek to examine the Chicanos’ fluid spatial identity in their searches for a real home, in Pat Mora’s “House of Houses”, Sandra Cisneros’ “The House on Mango Street”, Gloria Anzaldúa’s “Borderlands/La Frontera”. I argue that in these literary and autobiographical works, the cosy domestic home is impossible to find because of constant displacement and imposed mobility.
The American Beserk. Young Terrorists as Archetypes in Contemporary American Culture

Published: December 2019

Ambiguity has played a central role in the formation of modern grammatical theory. The article revisits the topic of structural ambiguity in particular, by looking closely at the sentences ‘The shooting of the hunters is terrible’ and ‘Flying planes can be dangerous’, both taken from Chomsky’s works. The question posed is whether the data provided by corpora verify their ambiguity.
Translation Errors Across Genres: A Research Perspective
Authors: Cozma Mihaela
Published: December 2019

Even if there may be types of translation errors which have a rather general character, in most of the cases they are closely related to the genre that the text to be translated represents. The paper offers an analysis of the translation errors contained by the assignments of 30 MA students in Translation Studies from the West University of Timisoara, Romania. The assignments consist in the translation from English into Romanian of texts belonging to three different genres: travel guides, legislation, and medical case reports. The errors are analyzed both quantitatively and qualitatively, with a view to arriving at conclusions of relevance for the improvement of the training process.
English Compound Terms in Air Traffic and Waterways Transport and Traffic Engineering and their Translation into Serbian
Authors: Dimković-Telebaković Gordana
Published: December 2019

In this paper, we explore the morphological structure and semantics of 89 English compound terms and their Serbian equivalents, as employed in air traffic and waterways transport and traffic engineering. In order to facilitate the process of translating these English metaphorical compound lexemes into Serbian, 10 translation patterns and strategies are designed. The results of the analysis also show that English compound terms and translation equivalents in Serbian do not pattern in most cases. To obtain the findings, we develop a semantico-morpho-translation method.
The Mechanism of Implicature and Inference as Influenced by Primary Stimuli
Authors: Dimulescu Cristina
Published: December 2019

This paper attempts to explain language as a process of meaning creation by a speaker (implicature) and meaning disambiguation by a hearer (inference) at the basis of which there is a complex mechanism of reality perception, internalization and verbalization. This mechanism of implicature/inference is studied from two interconnecting perspectives: Conversation Analysis and Neuro Linguistic Programming. While the former investigates the function of the utterance in context, the latter explores the way speakers and hearers internalize reality depending on how they see, hear and feel the world around them.
Redesigning Summative Evaluation in Medical English
Authors: Pop Anişoara
Published: December 2019

Evaluation of discrete skills such as reading comprehension as well as vocabulary and grammar multiple choice testing are commonplace in Medical English examinations in higher education. But are these approaches to evaluation practically oriented enough so as to provide a clear image of what students can do with the language in a real life communicative context? This paper will present a case of projectbased evaluation with students in English for Medical Cosmetics likely to meet such challenges.
Free Speech in Public Employment: Has the Supreme Court Clarified Matters? An Empirical Analysis of the Impact of Lane v Franks
Authors: Connolly John P. , Wasserman Lewis M.
Published: December 2019

We employ a counterfactual treatment effect analysis to evaluate whether U.S. Courts of Appeals judges have changed their propensity to vote against plaintiffs in public employment free speech disputes following the Supreme Court’s 2015Lane v Franksdecision. In order to ensure a like-for-like comparison of votes before and after theLanedecision we employ a variant of the “straddle” approach, which entails identifying cases caught in the crosshairs of the upper court’s ruling and then comparing the votes with those of cases already decided. Our results underscore the importance of paying close attention to selection effects when evaluating the impact of legal changes on judicial behavior.
Aligning Quality Incentives and Tariff Adjustments: The Case of the Brazilian Electricity Distribution Sector
Authors: Corton Maria Luisa , Phillips Michelle Andrea , Zimmermann Aneliese
Published: December 2019

This study investigates the role of aligning tariff adjustments and quality incentives in a Price cap regulatory regime. According to theory costs and quality are positively related. If additional resources are needed to improve service quality, a high cost high quality utility could be at a disadvantage when tariffs are adjusted by an X-factor that does not include quality. The regulator of the electricity distribution sector of Brazil has set up a public ranking of utilities according to quality compliance at the same time that a quality component is added to the X-factor, in 2013. We develop a stochastic cost frontier integrating all components of the X-factor to rank the utilities based on this integrated efficiency. Comparing this rank with the regulator’s public rank we argue that the resulting differences highlight the importance of using the same factors to rank and adjust tariffs in the sector. Otherwise, incentives would be misplaced with respect to factors used in cost adjustments. In addition, our findings reveal that the utilities’ cost behavior with respect to quality depends on the volume of energy delivered. We believe these results could be considered by the regulator when setting incentives and considering factors to adjust tariffs.
The European growth synchronization through crises and structural changes
Authors: Uctum Merih , Uctum Remzi , Vijverberg Chu-Ping C.
Published: December 2019

In light of several economic and financial crises and institutional changes experienced by the European countries, we examine whether these economies achieved synchronization of their business cycles and fostered synchronization of their growth rates. Controlling for reverse causality, we conduct multiple endogenous break tests and find that (i) several endogenous break dates correspond to idiosyncratic shocks affecting individual countries or major shocks in international arena but not the adoption of the euro; this result suggests that the convergence process has been nonlinear for a number of countries and that studies imposing break dates exogenously, such as the launch of euro, may lead to biased conclusions; (ii) while output growth was increasingly synchronized for some countries, integration occurred in an asymmetric way and it did not change or did not occur for others despite being in the same common currency area (iii) convergence has been prevalent among the non-Eurozone economies in our sample.
Was ist mit der Philosophie in Spiritual Care?
Authors: Schuchter Patrick
Published: December 2019

Im Spiritual Care-Diskurs kommen philosophische Traditionen und Zugänge zu Spiritualität kaum bis gar nicht vor. Referenzdiskurse und -felder sind vor allem die Religionen und die Religionswissenschaft, die Seelsorge, die Psychotherapie. Demgegenüber steht die historische Tatsache, dass Philosophie in der Antike, aber auch in der gegenwärtigen Bewegung der „Philosophischen Praxis“, durchaus als eine spirituelle Praxis gelebt und konzipiert wird. Der Rückgriff auf die antike, insbesondere hellenistische Tradition eines spirituell-sorgenden Philosophierens ist historisch der Königsweg, die Philosophie als explizite Traditionslinie in Spiritual Care zu positionieren. Der Artikel beschreibt vier philosophische Übungen, begründet deren Bedeutung im spezifischen Standpunkt, von den Grenzen des Daseins her zu denken und fühlen zu lernen, und erläutert die dialogisch-zuhörende Einbettung der philosophischen Meditationen. Ein kleiner, praktischer Leitfaden soll der Übersetzung in die Praxis dienen.
Effects of α-lactalbumin and sulindac on primary and metastatic human colon cancer cell lines
Authors: Aydemir Işıl , Vatansever Seda , Özbilgin Kemal
Published: December 2019

Background

HAMLET (human α-lactalbumin made lethal to tumor cells) and sulindac are active ingredients which are used in the treatment of cancers. Under both in vivo and in vitro conditions, HAMLET binds to the surface of tumor cells and enters the cells. Sulindac is one of nonsteroidal anti-inflammatory drugs. It inhibits the growth of tumor cells by inducing the apoptosis. In our study, we aimed to investigate effects of α-lactalbumin and sulindac on COLO-320 primary and COLO-741 metastatic human colon carcinoma cell lines via mitochondrial apoptotic pathway by indirect immunocytochemistry and TUNEL assays.

Materials and methods

The effects of α-lactalbumin and sulindac were assessed by using MTT assay at 24, 48 and 72 h and apoptosis markers caspase-3, caspase-9 and cytochrome-c were detected using immunocytochemistry and TUNEL methods.

Results

It was appeared that α-lactalbumin and sulindac may triggger mechanisms of apoptosis in both primary and metastatic colon carcinoma cell lines and the primary colon carcinoma cell line was affected more than the metastatic cells.

Conclusion

It is proposed that α-lactalbumin and sulindac can be used in cancer treatments and future in vivo experiments.
Landau Quantised Modification of Rayleigh–Taylor Instability in Dense Plasmas
Authors: Shahid M. , Rasheed A. , Kanwal Misbah , Jamil M.
Published: December 2019

Effects of Landau quantisation and exchange-correlation potential on Rayleigh–Taylor instability (RTI)/gravitational instability are investigated in inhomogeneous dense plasmas. Quantum hydrodynamic model is used for the electrons, while the ions are assumed to be cold and classical. RTI is modified with the inclusion of Landau quantisation related to plasma density, ambient magnetic field, exchange speed, and modified Fermi speed. Owing to the exchange-correlation effects, gravitational instability increases, whereas the Landau quantisation effects contribute in the opposite way for quantisation factor η < 1. Since the exchange-correlation potential is a function of density, by controlling the number density and magnetic field one can control RTI.

FQ columnist Caetlin Benson-Allott identifies a new, noteworthy pattern in North American cinema: independent filmmakers crafting narratives about African-American rural women struggling to survive oppressive white communities. Centering her discussion around Nia DaCosta's Little Woods (2018), Jasmin Mozaffari's Firecrackers (2018), and Tate Taylor's Ma (2019), Benson-Allott suggests that these films allow viewers to glimpse the intersections of race, gender, and geography rarely explored in mainstream media.
Bologna, My Love: Il Cinema Ritrovato
Authors: Marcantonio Carla
Published: December 2019

FQ books editor Carla Marcantonio guides readers through the 33rd edition of Il Cinema Ritrovato Festival held each year in Bologna at the end of June. Highlights of this year's festival included a restoration of one of Vittorio De Sica's hard-to-find and hence lesser-known films, the social justice fairy tale, Miracolo a Milano (Miracle in Milan, 1951). The film was presented by De Sica's daughter, Emi De Sica, and was an example of the ongoing project to restore De Sica's archive, which was given to the Cineteca de Bologna in 2016. Marcantonio also notes her unexpected responses to certain reviewings; Apocalypse Now: Final Cut (2019), presented by Francis Ford Coppola on the large-scale screen of Piazza Maggiore and accompanied by remastered Dolby Atmos sound, struck her as a tour-de-force while a restoration of David Lynch's Blue Velvet (1986) had lost some of its strange allure.
You Don't Own This War: Arab Women's Cinema Showcase
Authors: Turan Müge
Published: December 2019

With only nine films, “Here and Now: Contemporary Arab Women Filmmakers,” a film series exhibited in August 2019 at Toronto's TIFF Bell Lightbox, is inevitably limited in the variety of style, form, and storytelling it can convey. However, by highlighting both the diversity and intersectionality of identities, the films presented are linked by a compelling thematic thread: they all investigate how cinema represents Arab women with a focus on the body, its materiality, and the power relations that determine it. Although each film reflected its local political and socio-economic context, collectively these films by Arab women utilized the body as a mediated object with the potential to destabilize, disrupt, and transform.
La incidencia de la violencia y criminalidad en la localización sectorial de las empresas en el occidente de México
Authors: Hernández Angeles José Luis
Published: December 2019

La localización y concentración de la actividad económica responde a muchos factores —algunos de ellos positivos y otros negativos— que desde la perspectiva de la teoría económica provocan economías de aglomeración. Uno de los elementos desfavorecedores y que provocan externalidades negativas son el crimen y la violencia (Hampley y McPheters, 1975; Pichardo-Muñíz y Chavarría, 2016). En particular, aquellos que afectan directa e indirectamente a las empresas son los analizados en el presente estudio. Los resultados obtenidos que aplican técnicas de análisis espacial y econometría lineal indican que, para el occidente de México, la afectación por la delincuencia oficialmente reportada es dispar y altamente dependiente de los sectores económicos analizados.No obstante, en la mayoría de los casos, factores que generan externalidades positivas, como el nivel educativo, son significativamente relevantes y acordes a los planteamientos propuestos.

Drawing from the consideration of cultural values as an explanatory factor of economic development, this article correlates the cultural traits reported by Hofstede’s Cultural Dimension model with the results in terms of industrialization for Colombia and selected cultural clusters. By contrasting industrialization-oriented policy choices with the evolution of export composition and industrial competitiveness indicators, we conclude that guided by a short-term, materialistic, nepotistic, and intolerant to uncertainty orientation, Colombian economic authorities and elites have helped in the prolongation of an underdeveloped industrial structure by favoring closed groups through extractive institutions, while Asia, instead of adopting ‘western values’, has drawn upon a long-term orientation to implement risky but sound, coordinated, and convergent social and economic policies in order to industrialize.

This study aims to determine the cash out transactions that occur in the Sabilurrosyad Islamic boarding school, analyze the internal control system, then compile the AIS cash outflow chart for the Sabilurrosyad boarding school so that it can increase public accountability. The research method is descriptive qualitative method using case studies. The results of the study indicate that internal control is still not good as evidenced by the existence of multiple tasks. Understanding of risk is still not understood by the leaders of Islamic boarding schools, information and communication is unclear. Monitoring has been carried out with the existence of monthly and annual financial reports, but it has not been compiled according to the accounting standards that should be. The flow chart has not been created so that the results of this study are in the form of a cash flow chart AIS can be used by the Sabilurrosyad boarding school.

An emerging evidence suggests that microRNAs (miRNAs) may be reliable biomarkers for inflammation or oncogenesis. The aim of this study was to investigate the diagnostic value of miR-23a and miR-181b in patients with irritable bowel syndrome (IBS) and patients with colorectal cancer (CRC) vs. healthy controls. Forty patients with IBS (29 females, 11 males), 33 patients with CRC (14 females, 19 males), and 33 healthy controls (17 females, 16 males) were prospectively included. Serum levels of miRNAs were evaluated by quantitative reverse transcription PCR. MiR-23a and miR-181b had significantly higher serum levels (p = 0.0009 and p = 0.004, respectively) in IBS patients than in controls. Serum levels of miR-23a and miR-181b in CRC patients were also significantly higher than in controls (p = 0.002 and p = 0.029, respectively). The levels of miR-23a and miR-181b in CRC vs. IBS patients suggested a trend of overexpression in patients with CRC, however, without statistical significance (p = 0.169 and p = 0.179, respectively). miRNet and Reactome database showed phosphatase and tensin homolog (PTEN) to be a major common pathway, suggesting inflammation as a central mechanism. MiRNAs may serve as reliable biomarkers in clinical practice, but further studies are necessary to establish a cut-off limit for specific miRNAs in different diseases.

Authors: KEMPA Rudolf
Published: December 2019

If the distribution of teachers is only
carried out following the political interests and desires of the authorities,
it will have an impact on the accumulation of teachers’ schools in the city,
while there are lack of teachers in remote areas schools. This study aims to evaluate
the policy of the Regional Government of Southwest Maluku Regency in the
distribution of High School/Vocational High School teachers. The approach used
in this study is an evaluative approach using data collection techniques in the
form of interview methods and documentation. Data analysis uses a triangulation
approach from the point of view of the resource person. The results of this
study indicate there are already local government policies related to equitable
distribution of teacher in Southwest Maluku Regency; Negative Impacts are Excess
number of subject teachers and unfulfilled compulsory teaching hours of
teachers. The results of this study are expected to be to be an input for the
local government in implementing policies of equitable distribution of teacher.
Department of Education and Culture of Maluku Province is expected to provide
input to local governments and related institutions so that the policy of
equitable distribution of teacher runs according to the aspirations of teachers
and schools

This research aims at determining the effect of
learning models on motivation, creative thinking skills, and cognitive learning
results of  students of Senior High
School 6 of Ambon, Indonesia. This research is a quasi-experimental
research using a non-equivalent pretest-post-test control group design. The
subjects of this research were class XI Science students with the total number
of 40 students. One group was taught by using the Modified Problem Based
Learning (M-PBL) and the other group was taught by using the discovery learning
model. Research data were collected using test and non-test instruments. The
data were analyzed by using ANCOVA with a significance level of 5%. The results
of the analysis show that the significance value of the learning model towards
students’ learning motivation and cognitive learning results was 0.000<0.05.
The significance value of learning model towards students' academic skill was
0.000<0.05. The significance value of the learning model towards
students' creative thinking skills was 0.030<0.05. The significance value of
the interaction between learning models and students' academic ability towards
students' cognitive learning results was 0.084>0.05. The results of this
research indicate that the implementation of M-PBL learning model has an effect
on students’ learning motivation, creative thinking skills, and learning
results better than that of the discovery learning model

Published: December 2019

This article provides an overview of educational
values ​​contained in Randai Minangkabau art, Indonesia. Randai
is one of the folk arts and local wisdom for the Minangkabau people, West
Sumatra, Indonesia. Educational values ​​from
Randai art can be integrated into the learning process as an effort to build the
talents and character of students. The research was a qualitative descriptive
study focused on ethnopedagogic fields. Data was obtained through interviews
with traditional leaders, Minangkabau culturalists and Randai art trainers,
West Sumatra, Indonesia. Based on the research that has been carried out, the
results show that the educational value of Randai was grouped into three parts,
namely: the philosophy of Randai art, the value of education in preparation for
the Randai performance and the value of education in the performance of Randai.
Philosophically, Randai's art aims at character education delivered through Kaba (stories). In preparation for Randai,
there were several educational values ​​including:
Barundiang (negotiating) principally
at bulek kato dek mufakaik and
bakarajosamo (in collaboration). Meanwhile, from the performance of Randai,
there was an educational value that was reflected in the activities of pasambahan, Kaba, garak malingka and the dramatic act of kato nan ampek. Educational values ​​from
Randai art that had been identified pedagogically can be integrated in the
learning process, especially learning Biology.

Published: December 2019

Gifted education has received more attention all over the
world, including UAE, because of its significant contribution in economic
investment.  This quantitative
study aimed to describe and analyze mathematics teacher perceptions toward
teaching gifted learners in general education classrooms in the UAE.  The survey consisted of 19 statements on a 5-
point Likert scale. The survey conducted among 66 teachers. Survey results were
analyzed based on two factors: teacher competency and perceptions about the
effectiveness of gifted learner programs. The results showed general positive
attitudes toward gifted education. More specifically, teachers showed positive
perceptions toward their competency to teach gifted students, while they mostly
held negative perceptions regarding the effectiveness of gifted programs. In
addition, teaching level (cycle1, cycle2, cycle3) impacts teacher perceptions regarding
their competency to teach gifted students and the applied gifted programs in
their schools. However, more research is needed as this study was limited to Al
Ain city teachers.

The theory about character education is
not new thing anymore, but in an effort to internalize the values of humanity
has not been studied, particularly in the current development, where there are
still many people who underestimated the existence of pesantren as a
terrorist base. In this qualitative case study, we examine a pesantren
in the practice of learning emphasizes the characters learning in an effort to
foster human values. Data taken used direct observation techniques and
interview with the informants (kiai, teacher and santri). Our
results suggest that pesantren are educational institutions which are
very effective in developing character in students (santri) especially
on human values which ensure the unity of the nation. This research gives
evidence that pesantren in Indonesia are friendly Islamic educational
institutions, uphold human rights, democratic, pluralist, and tolerant toward
religion. It becomes important to be known by people worldwide to uphold world
peace.
Discrete Stochastic Regulator on a Manifold, Minimizing Dispersion of the Output Macrovariable

Published: December 2019

A theoretical result is presented in the form of a new algorithm for the synthesis of a control system over a non-linear object, whose mathematical model represents a stochastic matrix difference equation having noise with a zero mean and finite dispersion in the righthand part. The new algorithm for synthesizing stochastic control for such an object is based on a three-stage procedure. In the first stage, the structure of the control system is formed in accordance with the classical method of analytical design of aggregated regulators (ADAR) in a fixed-noise assumption. In the second stage, the conditional mathematical expectation of the resulting expression for the first-stage control is determined. In the third stage, the control model is refined by excluding the noise variable from the control formula based on decomposing the initial control system affected by the new control. It is shown that the proposed control strategies minimize the target macro variable dispersion and ensure a stable, on average, achievement of the target manifold. A detailed example of an application of the algorithm for synthesizing control over the motion of an immobile center of mass is given, whose analog is represented by the objects such as by robot-manipulators, is given. The results of numerical modeling are presented, which confirm the operability of the constructed controller. Numerical simulations of the designed control system was performed using the authentic working equipment data.
