Self-stabilized soliton generation in a microresonator through mode-pulled Brillouin lasing
Authors: Do In Hwan , Kim Dohyeong , Jeong Dongin , Suk Daewon , Kwon Dohyeon , Kim Jungwon , Lee Jae Hoon , Lee Hansuek
Published: March 2021

Reducing the complexity required for starting and maintaining a soliton state has been a major task to fully miniaturize soliton microcombs including the accompanying external operating systems. Here we experimentally examine the generative process of a self-stabilized soliton in which a continuous-wave pump detuned on the thermally stable blue side of a resonance generates a Brillouin lasing signal that relays the pump power to the soliton pulses via intracavity mode-coupling without breaking thermal self-stability. Based on a simple setup consisting of a free-running laser and a microcavity without any external feedback systems by virtue of internal thermal locking, single-soliton pulses of 11 GHz repetition rate were deterministically generated. We demonstrate that the single-soliton pulses can be passively maintained over several days in a laboratory environment with a phase noise performance of

Changes in both trans- and cis-regulatory elements mediate insecticide resistance in a lepidopteron pest, Spodoptera exigua
Authors: Hu Bo , Huang He , Hu Songzhu , Ren Miaomiao , Wei Qi , Tian Xiangrui , Esmail Abdalla Elzaki Mohammed , Bass Chris , Su Jianya , Reddy Palli Subba
Published: March 2021

The evolution of insect resistance to insecticides is frequently associated with overexpression of one or more cytochrome P450 enzyme genes. Although overexpression of CYP450 genes is a well-known mechanism of insecticide resistance, the underlying regulatory mechanisms are poorly understood. Here we uncovered the mechanisms of overexpression of the P450 gene, CYP321A8 in a major pest insect, Spodoptera exigua that is resistant to multiple insecticides. CYP321A8 confers resistance to organophosphate (chlorpyrifos) and pyrethroid (cypermethrin and deltamethrin) insecticides in this insect. Constitutive upregulation of transcription factors CncC/Maf are partially responsible for upregulated expression of CYP321A8 in the resistant strain. Reporter gene assays and site-directed mutagenesis analyses demonstrated that CncC/Maf enhanced the expression of CYP321A8 by binding to specific sites in the promoter. Additional cis-regulatory elements resulting from a mutation in the CYP321A8 promoter in the resistant strain facilitates the binding of the orphan nuclear receptor, Knirps, and enhances the promoter activity. These results demonstrate that two independent mechanisms; overexpression of transcription factors and mutations in the promoter region resulting in a new cis-regulatory element that facilitates binding of the orphan nuclear receptor are involved in overexpression of CYP321A8 in insecticide-resistant S. exigua.
AKT-dependent signaling of extracellular cues through telomeres impact on tumorigenesis
Authors: Sánchez-Vázquez Raúl , Martínez Paula , Blasco Maria A.
Published: March 2021

The telomere-bound shelterin complex is essential for chromosome-end protection and genomic stability. Little is known on the regulation of shelterin components by extracellular signals including developmental and environmental cues. Here, we show that human TRF1 is subjected to AKT-dependent regulation. To study the importance of this modification in vivo, we generate knock-in human cell lines carrying non-phosphorylatable mutants of the AKT-dependent TRF1 phosphorylation sites by CRISPR-Cas9. We find that TRF1 mutant cells show decreased TRF1 binding to telomeres and increased global and telomeric DNA damage. Human cells carrying non-phosphorylatable mutant TRF1 alleles show accelerated telomere shortening, demonstrating that AKT-dependent TRF1 phosphorylation regulates telomere maintenance in vivo. TRF1 mutant cells show an impaired response to proliferative extracellular signals as well as a decreased tumorigenesis potential. These findings indicate that telomere protection and telomere length can be regulated by extracellular signals upstream of PI3K/AKT activation, such as growth factors, nutrients or immune regulators, and this has an impact on tumorigenesis potential.
An amplified derepression controller with multisite inhibition and positive feedback
Authors: Drobac Gorana , Waheed Qaiser , Heidari Behzad , Ruoff Peter
Published: March 2021

How organisms are able to maintain robust homeostasis has in recent years received increased attention by the use of combined control engineering and kinetic concepts, which led to the discovery of robust controller motifs. While these motifs employ kinetic conditions showing integral feedback and homeostasis for step-wise perturbations, the motifs’ performance differ significantly when exposing them to time dependent perturbations. One type of controller motifs which are able to handle exponentially and even hyperbolically growing perturbations are based on derepression. In these controllers the compensatory reaction, which neutralizes the perturbation, is derepressed, i.e. its reaction rate is increased by the decrease of an inhibitor acting on the compensatory flux. While controllers in this category can deal well with different time-dependent perturbations they have the disadvantage that they break down once the concentration of the regulatory inhibitor becomes too low and the compensatory flux has gained its maximum value. We wondered whether it would be possible to bypass this restriction, while still keeping the advantages of derepression kinetics. In this paper we show how the inclusion of multisite inhibition and the presence of positive feedback loops lead to an amplified controller which is still based on derepression kinetics but without showing the breakdown due to low inhibitor concentrations. By searching for the amplified feedback motif in natural systems, we found it as a part of the plant circadian clock where it is highly interlocked with other feedback loops.
Linking bacterial enterotoxins and alpha defensin 5 expansion in the Crohn’s colitis: A new insight into the etiopathogenetic and differentiation triggers driving colonic inflammatory bowel disease

Evidence link bacterial enterotoxins to apparent crypt-cell like cells (CCLCs), and Alpha Defensin 5 (DEFA5) expansion in the colonic mucosa of Crohn’s colitis disease (CC) patients. These areas of ectopic ileal metaplasia, positive for Paneth cell (PC) markers are consistent with diagnosis of CC. Retrospectively, we: 1. Identified 21 patients with indeterminate colitis (IC) between 2000–2007 and were reevaluation their final clinical diagnosis in 2014 after a followed-up for mean 8.7±3.7 (range, 4–14) years. Their initial biopsies were analyzed by DEFA5 bioassay. 2. Differentiated ulcer-associated cell lineage (UACL) analysis by immunohistochemistry (IHC) of the CC patients, stained for Mucin 6 (MUC6) and DEFA5. 3. Treated human immortalized colonic epithelial cells (NCM460) and colonoids with pure DEFA5 on the secretion of signatures after 24hr. The control colonoids were not treated. 4. Treated colonoids with/without enterotoxins for 14 days and the spent medium were collected and determined by quantitative expression of DEFA5, CCLCs and other biologic signatures. The experiments were repeated twice. Three statistical methods were used: (i) Univariate analysis; (ii) LASSO; and (iii) Elastic net. DEFA5 bioassay discriminated CC and ulcerative colitis (UC) in a cohort of IC patients with accuracy. A fit logistic model with group CC and UC as the outcome and the DEFA5 as independent variable differentiator with a positive predictive value of 96 percent. IHC staining of CC for MUC6 and DEFA5 stained in different locations indicating that DEFA5 is not co-expressed in UACL and is therefore NOT the genesis of CC, rather a secretagogue for specific signature(s) that underlie the distinct crypt pathobiology of CC. Notably, we observed expansion of signatures after DEFA5 treatment on NCM460 and colonoids cells expressed at different times, intervals, and intensity. These factors are key stem cell niche regulators leading to DEFA5 secreting CCLCs differentiation ‘the colonic ectopy ileal metaplasia formation’ conspicuously of pathogenic importance in CC.
Informed consent rates for neonatal randomized controlled trials in low- and lower middle-income versus high-income countries: A systematic review

Published: March 2021

Objective

Legal, ethical, and regulatory requirements of medical research uniformly call for informed consent. We aimed to characterize and compare consent rates for neonatal randomized controlled trials in low- and lower middle-income countries versus high-income countries, and to evaluate the influence of study characteristics on consent rates.

Methods

In this systematic review, we searched MEDLINE, EMBASE and Cochrane for randomized controlled trials of neonatal interventions in low- and lower middle-income countries or high-income countries published 01/01/2013 to 01/04/2018. Our primary outcome was consent rate, the proportion of eligible participants who consented amongst those approached, extracted from the article or email with the author. Using a generalised linear model for fractional dependent variables, we analysed the odds of consenting in low- and lower middle-income countries versus high-income countries across control types and interventions.

Findings

We screened 3523 articles, yielding 300 eligible randomized controlled trials with consent rates available for 135 low- and lower middle-income country trials and 65 high-income country trials. Median consent rates were higher for low- and lower middle-income countries (95.6%; interquartile range (IQR) 88.2–98.9) than high-income countries (82.7%; IQR 68.6–93.0; p<0.001). In adjusted regression analysis comparing low- and lower middle-income countries to high-income countries, the odds of consent for no placebo-drug/nutrition trials was 3.67 (95% Confidence Interval (CI) 1.87–7.19; p = 0.0002) and 6.40 (95%CI 3.32–12.34; p<0.0001) for placebo-drug/nutrition trials.

Conclusion

Neonatal randomized controlled trials in low- and lower middle-income countries report consistently higher consent rates compared to high-income country trials. Our study is limited by the overrepresentation of India among randomized controlled trials in low- and lower middle-income countries. This study raises serious concerns about the adequacy of protections for highly vulnerable populations recruited to clinical trials in low- and lower middle-income countries.
Sequential targeting of interferon pathways for increased host resistance to bacterial superinfection during influenza
Authors: Barman Tarani Kanta , Racine Rachael , Bonin Jesse L. , Califano Danielle , Salmon Sharon L. , Metzger Dennis W.
Published: March 2021

Bacterial co-infections represent a major clinical complication of influenza. Host-derived interferon (IFN) increases susceptibility to bacterial infections following influenza, but the relative roles of type-I versus type-II IFN remain poorly understood. We have used novel mouse models of co-infection in which colonizing pneumococci were inoculated into the upper respiratory tract; subsequent sublethal influenza virus infection caused the bacteria to enter the lungs and mediate lethal disease. Compared to wild-type mice or mice deficient in only one pathway, mice lacking both IFN pathways demonstrated the least amount of lung tissue damage and mortality following pneumococcal-influenza virus superinfection. Therapeutic neutralization of both type-I and type-II IFN pathways similarly provided optimal protection to co-infected wild-type mice. The most effective treatment regimen was staggered neutralization of the type-I IFN pathway early during co-infection combined with later neutralization of type-II IFN, which was consistent with the expression and reported activities of these IFNs during superinfection. These results are the first to directly compare the activities of type-I and type-II IFN during superinfection and provide new insights into potential host-directed targets for treatment of secondary bacterial infections during influenza.
Humbling the human: Posthuman explorations in contemporary short fiction
Authors: D’hoker Elke
Published: March 2021

In a context of manmade global warming, ecological destruction and species extinction, posthumanist scholars have advocated moving beyond the anthropocentrism that determines western thinking in favour of an embedded and embodied interspecies relationality. If these remain fairly abstract notions in the work of critics such as Donna Haraway and Rosi Braidotti, contemporary short fiction provides many interesting examples of these alternative forms of being and becoming. The short story seems especially suited to exploring this decentring of the human subject, given its own status as a liminal, ‘minor’ or ‘humble’ genre and its long tradition of exploring human–animal relations in animal stories. This article demonstrates how contemporary short stories by Lauren Groff, Claire-Louise Bennett, Sarah Hall, Sara Baume and Louise Ehrdrich stage a profoundly biocentric perspective by moving beyond animal stories’ traditional modes of the fabular and the figural towards a realistic depiction of our creaturely existence in experiences that may be at once empowering and terrifying.
‘The extremely private literary giant’: Alice Munro’s poetics of humility
Authors: Cox Ailsa
Published: March 2021

When the Nobel Prize committee awarded the laureateship to Alice Munro in October 2013, someone or something called ‘Alice Munro’ was immediately placed under a media spotlight. She had, over the years, accrued what Lorraine York has called ‘reluctant celebrity’, regularly gathering literary prizes, but making relatively few personal appearances. In the first decade of the twenty-first century she had become more visible in public whilst still retaining a degree of ambivalence. This ambivalence was evident in the brief interviews she gave in the weeks after the announcement, following which she returned to her private life and the retirement from writing that she had already announced. This article combines an interrogation of Munro’s humble public persona with an investigation into her poetics of short fiction, referring to her published texts and interviews. It concludes with some personal reflections on writing about a living author at the end of her career.

International students at the Centro Sperimentale di Cinematografia in Rome: 1935–2020: A history to be written
Authors: Laviosa Flavia , Baldi Alfredo , Carter Jim , Bonelli Diego
Published: March 2021

The Centro Sperimentale di Cinematografia (CSC), founded in Rome in 1935, has come to signify Italian cinema education in acting, directing, photography, set design, costume design, screenwriting, sound production, editing, production and film animation (since 1983). The CSC has historically admitted a significant number of international students (more than 13 per cent) in the past 85 years. This collaborative article introduces the first comprehensive list of international students in three CSC disciplines: directing, photography and set design. It begins with historical and artistic perspectives addressing the ideal of diversity, the internationalization of culture and the sociopolitical context of studying cinema in Rome. This article also includes graphs and statistics that give a clear sense of the broad geographical representation of foreigners who studied at the CSC. A comprehensive list of their names, nationalities, specializations and year of their degrees is organized in two formats: one by geography and one by chronology. The aim of this article is also to set new research goals so as to broaden our understanding of whether and how the CSC’s Italian cinematic education impacted world cinema.

Rural geographies and the New Chinese Cinemas: Imaging progressive places in Hou Hsiao-Hsien’s Dust in the Wind and Jia Zhangke’s Platform
Authors: Lo Dennis
Published: March 2021

The New Chinese Cinemas were unprecedented in critiquing official narratives of progress through dramatic location-shot images of rural Taiwan and China. Much more than standing in as a picturesque backdrop, the rural was a site of complex ideological contestations. Yet, existing scholarship overlooks the richness of rural representations, reductively interpreting rural films as works of nostalgia and cultural salvage. Through a comparative analysis of representations of landscape, travel and visual perception in Hou Hsiao-Hsien’s Dust in the Wind () and Jia Zhangke’s Platform (), this article brings into focus the important but largely ignored roles that Hou and Jia have played in envisioning new frameworks for thinking about rural geographies. Drawing from Doreen Massey’s notion of the ‘progressive place’, I investigate how Jiufen and Fenyang – the films’ shooting locations – are stages upon which the directors experimented with imaging and imagining communities. Jiufen is represented in Dust as a porous interface between the urban and rural, a metonym for the film’s representation of Taiwan as a contact zone with China. Platform, by contrast, fashions an image of Fenyang as a non-place, a microcosm of China as it undergoes unchecked neo-liberal development. Significantly, these films went beyond revising rural imaginaries on-screen, to making a material impact on Jiufen and Fenyang by transforming them into landmarks of global film tourism. This work demonstrates how Hou and Jia responded to disorienting social changes not by resisting, but by tactically embracing the blurring of divides between the urban and rural, and local and global.
An unconventional zombie: Subcultural genres, global art cinema and bio-power in Sebastian Hofmann’s Halley (2012)
Authors: Vera Cristina Ruiz-Poveda
Published: March 2021

With an unconventional living-dead protagonist and a minimalist auteur style,Halleybrings to the fore how the tensions between genre movies and art cinema operate in a transnational context.Halleysurprises the audience with the story of a security guard who is dead but remains alive. While his flesh decomposes, Beto goes to work and continues with his lonely life pretending that everything is fine. In this sense, the film presents an unconventional zombie: Beto is not a monster, he is harmless and he is an obedient worker, but his condition exhibits his alienation in society. This article analyses Beto’s impossible embodiment from the perspective of film categorization, taking into account the intersections between auteur cinema and subcultural genres such as zombie movies in a transnational context. To that end, I rely on Dolores Tierney’s mapping of cult cinema in Latin America as well as on Ignacio Sánchez Prado’s analysis of global art cinema in México, both of which are related to international film circuits. Secondly, this article focuses on the sociopolitical implications of Beto’s living-dead body. I trace the trope of the living-dead character and analyse its political commentary from the perspective of bio-power. Drawing from Giorgio Agamben’s exploration of the homo sacer and bare life, this article explores how Beto’s embodiment evokes his diminished agency but also its subversive potential. With a body that transcends basic medical categorizations of life and death, Beto confronts Foucault’s idea of bio-power and resists the clinic.
Film as dialogue: Documentary theorization through practice
Authors: Semege Mahoro
Published: March 2021

A large body of documentary scholarship approves of the documentary’s effectiveness in addressing social issues beneficially. However, documentaries that have been made with the primary aim of testing such effectiveness are rare. This article presents the findings based on a documentary made specifically to test this theory. Titled Forsaken, the documentary was made and used as a test tool to assess its rhetorical ability to generate pledges for support of neglected adolescent orphans in South African communities. This article highlights the documentary’s rhetorical strategies and the extent to which such strategies led audience members to pledge support for this category of orphans. Contrary to views in the extant literature that pay little attention to the contextual limitations of the documentary’s rhetorical principles, the present article argues that a documentary’s effectiveness in addressing social issues beneficially is largely dependent on the cultural attuning of the documentary’s rhetorical principles.
The post-2000 Hong Kong young filmmakers: Embrace, resistance and new chances
Authors: Chen Fangyu
Published: March 2021

This article is a text-based analysis of 107 Hong Kong local productions produced from 2000 to August 2018. These films are made by the current young generation of filmmakers who joined the industry in the new millennium, when it gradually entered an era marked by the domination of Hong Kong–mainland co-productions. With the aim of expanding the scholarly discussion on the emerging ‘Hong Kong SAR New Wave Cinema’, it identifies four themes that recurrently appear in their films: (1) a tendency to feature people with physical or mental disabilities as their protagonists; (2) the possession of a sense of nostalgia for the glorious 1980s; (3) a manifestation of larger Hong Kong–mainland relations through characters; and (4) varying degrees of politicization. The young generation of filmmakers, whose works denote the social responsibility these young people bring to their filmmaking, shows their greater engagement with civic issues, less consideration of the mainland market and capital and a stronger desire to tell local Hong Kong stories, preserve local Hong Kong culture and emphasize the Hong Kong identity it represents. These traits, as the conclusion argues, are rooted deeply in economic, cultural and political realities.
Colonial representations of Macao and the Macanese: Circulation, knowledge, identities and challenges for the future
Authors: de Matos Patrícia Ferraz
Published: March 2021

This article intends to contribute towards the study of harbour cities, reflecting on the circulation of things and people, matters associated with national borders and multiple identities that cross paths there. Considering the history of Macao, its relationship with the Portuguese colonial empire and the challenges posed to the Macanese identity, this article intends to analyse representations of Macao and the Macanese produced in Portugal during the colonial period, considering some of them may still have repercussions today. Representations in generally accessed documents, such as the periodical press, will be analysed, as will events, such as great exhibitions, that were directed to a broader audience and which were frequently incorporated into colonial propaganda. By realizing that even today the movement towards the internationalization of Macao and China itself also involves Portugal, one concludes this is an interesting place for reflecting on power strategies, the circulation of individuals and the formation of identities.
The poetics and politics of ‘progress’ in neoliberal India: The state and its margins in Shanghai (2012)
Authors: Chakraborty Proshant
Published: March 2021

The contemporary Indian state is exemplified by contradictions. Its workings are marked by a simultaneous retreat and deepening of state power under neoliberalism as well as burgeoning governmentalities that both produce and police political dissent. Such framings of the state problematize received political wisdom on the relations between centre and margin, state and government, citizen and subject. Anthropological approaches to the state map out its complex organizational logics, which are further embedded in the exercise of power and violence. Drawing on such approaches, this article examines the 2012 Indian film Shanghai, directed by Dibakar Banerjee. Based on Greek author Vassilis Vassilikos’ 1966 novel Z, Shanghai represents the contemporary neoliberal Indian state’s workings in the fictitious periurban town of Bharatnagar, slated to become a world-class Special Economic Zone. However, when a left-wing activist opposing land acquisition is fatally injured in an ‘accident’, a state bureaucrat’s investigation unravels how the onward march of pragati (‘progress’) is undergirded by violence. Taking Shanghai as an example of ‘realist fiction’, I examine both representations and realities of the neoliberal Indian state using a thick and nuanced reading of the film’s narrative, cinematic details, context and characters, situating them in anthropological discussions on the state and its margins in contemporary India.
Sound and the masters: The aural in Indian art cinema
Authors: Bhattacharya Indranil
Published: March 2021

The study of art cinema has emerged as a richly discursive, but, at the same time, a deeply contested terrain in recent film scholarship. This article examines the discourse of art cinema in India through the prism of sound style and aesthetics. It analyses the sonic strategies deployed in the films of Satyajit Ray, Ritwik Ghatak, Mrinal Sen and Mani Kaul, in order to identify the dominant stylistic impulses of sound in art cinema, ranging from Brechtian epic realism on one hand to Indian aesthetic theories on the other. Locating sound as a key element in the discourse of art cinema, the article surveys the different modes through which aesthetic philosophies were translated into formal strategies of sound recording, designing and mixing. Using previous scholarship on art cinema in India as the point of departure, this study combines theoretically informed textual analysis with new historical insights on Indian cinema.

A fejlődés és fejlettség sokfélesége a számok tükrében = A GDP és néhány alternatív mutató értékének összevetése a világ országaiban
Authors: Lakócai Csaba
Published: March 2021

A közgazdaságtani gondolkodásban az elmúlt fél évszázad során fokozatosan teret nyert az a nézet, miszerint újra kell gondolni a gazdaság feladatait és célját, feladva a termelékenység és fogyasztás vég nélküli növekedésébe vetett hitet. A kezdetben még csak néhány elméleti kutató körében terjedő meggyőződést a 2008-as pénzügyi válság óta már több politikai döntéshozó is magáénak vallja, jóllehet egyelőre szerkezeti korlátai (is) vannak a gazdaság másfajta, fenntarthatóbb pályára állításának. Egy, a közeljövőben esedékes strukturális változásban kulcsszerepet kap az, hogyan és mivel mérjük a makrogazdaság teljesítményét. Jelen tanulmányban a GDP, mint a legelterjedtebb makrogazdasági mutató kerül összevetésre néhány alternatív fejlettségi-jól(l)éti mutatóval statisztikai adatok alapján, rámutatva a fejlődés különböző megjelenési formáinak összetettségére, amit a jövőben a jelenlegi gyakorlathoz képest jobban figyelembe kell venni a fenntarthatóság érdekében. Within the economic thinking, an opinion on the necessary reconsideration of the mission and objectives of the economy has gained ground over the past half century, giving up the belief in the infinite growth of productivity and consumption. Initially, this was only the conviction of a few theoretical scholars, but since the 2008 financial crisis, some decision makers agree with this thinking. However, there are still systemic limitations of switching the economy to a more sustainable path. In future structural transition, the question of how to measure the macroeconomic performance will be a key issue. In this paper, GDP, as the most broadly used economic index, is compared with some alternative welfare and wellbeing indices based on statistical data, underscoring the complexity and diversity of the different dimensions of progress and development. Decision makers should consider the latter fact more in the future than they do today.

A bruttó hozzáadott érték kiszámításának segítségével azonosítja a tanulmány a jól teljesítő élelmiszeripari ágakat, területi és különböző kategorizálási szempontok szerint elemzi azokat. A tanulmány eredményei alapján az élelmiszeripari vállalatok képesek jelentős hozzáadott érték előállítására, de ez területileg nagyon heterogén. Az iparágban érvényesül a méretgazdaságosság elve, jelentős potenciál főként a kis- és középvállalkozások esetén azonosítható. Agriculture is an important sector and has strategic role in the Hungarian economic policy. The changes in the subsidy scheme open up new opportunities and financial sources in agriculture. The paper summirizes these changes and gives a comprehensive picture of the primary sector relying on annual company reports and gross added value calculations. The results show that there is a territorial heterogeneity regarding gross added value in the Hungarian agriculture and economies of scale occurs, but the contribution of SMEs is well below its potential.
Specifikusság, mint migrációs ellenösztönző: elmélet és egy rendezett logit modell tanulságai = Specificity as counterincentive of migration: theoretical approach and the teaching of an ordered logit model
Authors: Golovics József
Published: March 2021

Jelen tanulmányban a nemzetközi migráció hagyományos mikroökonómiai elméletét bővítjük ki a Williamson-féle specifikusság koncepciójával. Amellett érvelünk, hogy bizonyos hely- és kapcsolatspecifikus beruházások megléte komoly ellenösztönzőként szolgálhat az elvándorlásra. A specifikusság fogalmával így a korábbi gazdasági megközelítések horizontján kívül eső empirikus megfigyeléseket is magyarázni tudjuk, emellett pedig bizonyos, a migráció közgazdaságtani modelljeiben meglévő tényezőket helyezünk új megvilágításba. Feltevéseinket egy elméleti keretben vázoljuk fel, majd egyéni szintű migrációs potenciálra vonatkozó Eurobarometer adatok és egy rendezett logit modell segítségével empirikusan is teszteljük őket. This paper integrates Williamson’s concept of specificity into the neoclassical microeconomic theory of international migration. It is claimed that certain site specific and relationship specific investments may be substantial disincentives to migrate. Thus, the concept of specificity can interpret several empirical findings that remained unexplained in former economic models. Besides, it can shed a new light on standard factors of these models as well. These claims are outlined in a theoretical framework and tested empirically by using individual Eurobarometer migration intention data and an ordered logit model.
Devizaárfolyam előrejelzés neurális háló modell segítségével = Foreign Exchange Rate Forecast Using Neural Network
Authors: Lakatos Zsolt
Published: March 2021

Modelljeimben a technikai indikátorok használatát kapcsolom össze a neurális hálós modellek előrejelző képességeivel. A technikai indikátorok használata mellett szól, hogy rövid távon a pénzügyi idősorok autokorreláltak, a neurális modellek pedig nemlineáris kapcsolatok modellezésére alkalmasak. A kapott eredmények révén azt a következtetést vontam le, hogy ugyan a neurális háló modellek optimalizációs képessége nagyon jó és alkalmazásukkal a megfelelő technikai indikátorok is meghatározhatók, de csak lassan képesek rátanulni az adatokra, így még a legkisebb tranzakciós költség alkalmazása mellett is csak a kezdeti befektetésünk elvesztését tudjuk halogatni. My present paper is the shortened version of my master's thesis in finance presented in November 2015, in which I presented the results of the research implemented in the Training Center for Bankers. In my models I combine the use of technical indicators with predictive capabilities of neural network models. The use of a technical indicator suggests that in the short term the financial timeseries are autocorrelated, and neural models are suitable for modeling nonlinear relationships. Based on the results I concluded that although the optimization capabilities of the neural network models are very good and their application can be determined by the appropriate technical indicators, but learning from timeseries data takes too much time, so even with the smallest transaction cost we can only delay the loss of our initial investment.
E-kereskedelem: szállítási díjjal vagy anélkül? = E-commerce: with or without shipping fee?
Authors: Kelemen József
Published: March 2021

A tanulmány az ingyenes házhozszállítás és a szállítási díjjal való árazás stratégiáját vizsgálja. Egy termék vásárlásakor házhozszállítás esetén felmerül a kérdés, hogy a termék árában benne kell lennie a szállítási díjnak vagy a kettőt szét kell választani, és a termék ára mellett külön meg kell jelennie annak? A probléma elemzéséhez Kelemen [2017b] modelljét alkalmazzuk, amit kiegészítünk a szállítási díjat kifogásoló fogyasztókkal. Egy olyan modellbe helyezzük az elemzést, ami a térbeliséget mélyrehatóbban veszi figyelembe a piac méretén, a szállítási díjon és az utazási költségen keresztül. A szállítási díjjal való árazás magasabb profitot eredményez, azonban ehhez a piacot jól kell ismerni. This paper studies the free shipping and partitioned pricing strategy (product price with shipping fee). If a product is ordered for delivery, it is not straightforward that the price should consist of the shipping fee or the product price and shipping fee should be separated. We extend the model of Kelemen [2017b] with shipping charge skepticism. In this framework, we can investigate the spatial properties in more detail through the size of the market, the shipping fee and the transportation cost. As a result of that, the partitioned pricing ensures higher profit, but it requires the knowledge of key characteristics of the market.

Published: March 2021

Disproportional burden of COVID-19 and vulnerability to containment measures in informal settlements have been recognised, however, the role of poor housing conditions in propagating these remains neglected. Poor housing conditions will make it difficult to effectively implement social distancing measures. With increased time spent in cramped, dark and uncomfortable indoor environments, water and sanitation outside the home, and no outdoor space, higher exposure to existing health hazards and high levels of stress, with women and children most vulnerable, are anticipated. We reflect on these interconnections and recommend immediate measures and the long-term need for adequate housing for health and well-being.
D-optimal Design Optimization for the Separation of Oleic Acid from Malaysian High Free Fatty Acid Crude Palm Oil Fatty Acids Mixture Using Urea Complex Fractionation
Authors: Bahadi Murad , Salih Nadia , Salimon Jumat
Published: March 2021

Oleic acid (OA) rich vegetable oils is important for the daily essential dietary oils intake but restrict to particular oil such as olive oil. However OA enrichment to other vegetable oil such as palm oil is always possible. OA can be obtained from cheap resources such as high free fatty acid crude palm oil (HFFA-CPO). OA concentrate from HFFA-CPO fatty acids mixture requires efficient and low cost technique. Urea complex crystallization fractionation is a classic method for fractionating saturated and monounsaturated fatty acids from polyunsaturated fatty acids of many vegetable oils. In this work, the separation and purification of oleic acid (OA) from unsaturated fatty acids mixture fraction (USFA) of HFFA-CPO fatty acids mixture by urea complex fractionation (UCF) was studied. The crystallization reaction conditions of urea inclusion for the non-urea complex fraction (NUCF) were optimized using the response surface methodology (RSM) and the optimal model was developed. The results showed high content of OA (88%) in urea complex fraction (UCF) with 86% yield at optimal conditions of urea-to-USFAs ratio of 4.62 : 1 (w/w), crystallization temperature at –10°C and crystallization time of 24 h. The results have demonstrated that urea complex crystallization fractionation method is a very effective with low cost, stable, obtainable, and comparatively ease to recover of OA from polyunsaturated fatty acids (PUFA) of an oil fatty acids mixture. Pure OA is plausible to be used back for the OA enrichment modification into palm oil for new dietary oil.
El trapo rojo, un faro de colores y la fiesta: un mundo de símbolos
Authors: González Pérez Marcos
Published: March 2021

Los símbolos hacen parte de las manifestaciones sociales y dan cuenta de las complejidades en que están inmersas las comunidades humanas. Este ensayo busca explicar las diversas formas en que colectivos o individuos hicieron público los problemas que afrontaban al inicio del periodo de la cuarentena en Colombia, específicamente en el mes de marzo de 2020. En una especie de juego de colores, colgaron trapos rojos para llamar la atención sobre sus necesidades económicas, trapos negros para denunciar la violencia contra las mujeres o trapos azules para reclamar respeto por los trabajadores de la salud. Esa gama de símbolos cruzó fronteras y les dio visibilidad a todas estas problemáticas. De esta situación no escapó la fiesta, y este escrito trata de descifrar las diversas formas en que esta manifestación patrimonial podría ser defendida frente a la pandemia desencadenada por el coronavirus.
Voguing, un grito retorcido contra la opresión. Soy todo y nada, sobre la danza de cuerpos desviantes
Authors: Nunes Barbosa Lucelina
Published: March 2021

Este artículo es una aproximación al cuerpo desde la especificidad de la danza “voguing” y la nociónde cuerpo no binario. Las reflexiones circundan los discursos de poder y dominación a que estamos subordinadas en nuestra cotidianidad y en el ámbitode la danza, y el “voguing” como expresión dancística activista de resistencia contra la marginación de grupos minoritarios integrados por gays, afroamericanos, migrantes latinos, transgéneros y queer. Este estilo dancístico y expresión de reafirmación social tipificó a la comunidad LGBTTTIQ en las décadas de 1980 y 1990. Abordamos aquí las prácticas corporales de jóvenes que bailan bajo la perspectiva de la diversidad y desarrollan diferentes abordajes somatopolíticos con un particular interés en expresiones dancísticas que revelan el cuerpo como objeto de consumo y signo a la vez. Se indaga sobre las aprobaciones hegemónicas utilizadas por los “voguers” como reivindicación contestataria que reproducegestos codificados de concepción binaria.
Antes y Ahora: espacio y tiempo andino en los diálogos de El zorro de arriba y el zorro de abajo
Authors: Alcón Tancara Sofía
Published: March 2021

El artículo explora, desde una mirada aimara, la visión del tiempo-espacio andino en los diálogos de El zorro de arriba y el zorro de abajo de José María Arguedas, inspirados en los relatos quechuas de Dioses y Hombres de Huarochirí. Asimismo, el artículo sugiere un modo distinto de interpretación de la realidad social de Chimbote en transformación. Por consiguiente, el artículo propone otras categorías y maneras de analizar la realidad social desde una perspectiva andina. Es una propuesta epistemológica distinta a las indigenistas de su tiempo. Para este análisis, se recurre a los relatos indígenas traducidos por Arguedas de la lengua quechua al castellano. Finalmente, se utiliza el archivo de la memoria oral para visibilizar un modo distinto de concebir y organizar el tiempo-espacio, y por consiguiente la palabra y el texto.
Psychoeducational programs in psychiatry – possibilities and limitations of their application
Authors: Majewicz Piotr
Published: March 2021

Psychoeducation is currently used in many areas of life, including psychiatry. It is difficult to imagine the modern process of treating people with mental disorders without the use of psychoeducation as a necessary, permanent element of this process, in addition to pharmacotherapy and psychotherapy. Psychoeducational programs are used primarily in the treatment of people with schizophrenia spectrum disorders and those suffering from bipolar affective disorder (BPAD). These programs are not only directed to the patient, but they are also addressed to their family members and friends. The article presents the possibilities of using selected psychoeducational programs, including the PEGASUS program, the Barcelona Psychoeducation Program and the Krakow Program for People with BPAD, as well as limitations of their application. The goals of these programs, their structure and effectiveness were also presented.
