Ecuadorian Teachers’ Perceptions of Teaching English: Challenges in the Public Education Sector
Authors: Orosz Agnes , Monzón Mirdelio , Velasco Paola
Published: May 2021

The current English curriculum in Ecuador requires high-school students graduate with an intermediate (B1) level. Attaining this target depends on several factors, such as teaching strategies employed in class and teacher training opportunities offered. Ecuador is ranked low for English language proficiency and, therefore, an exploratory approach has been conducted as the main data collection method to investigate the possible reasons for poor performance. In the previous phase of an overarching research project, round table discussions were held to explore themes related to English teachers’ pedagogical practices. The data gathering process in the phase described in the present study involved conducting in-depth interviews with 10 primary and secondary school English language teachers. The transcribed interviews were analyzed by putting the material through the MAXqda qualitative analysis software. The resulting coded categories allowed the authors to investigate three specific issues dealt with in the present research study, namely: teachers’ perceptions of the importance of learning English, actual classroom teaching practices, and the teachers’ observations on in-service training options. The findings of the study demonstrated that English teachers in Ecuadorian public schools recognized the importance of English and are making a substantial effort to keep up with the professional demands related to teaching English as a Foreign Language, but they lack the required knowledge to develop skills, such as critical thinking and creativity. They are also facing several challenges, such as a demanding new curriculum and students’ lack of motivation at a time of apparently dwindling teacher training opportunities.

The Potency of Senggani (Melastoma malabathricum L) Leaves in Repair of Pancreatic Beta Cells for Diabetes Mellitus Patients: A Narrative Review
Authors: Prayoga Galuh Rizal , Huda Aziz Syamsul , Sitepu Syndilona Br
Published: May 2021

Diabetes mellitus is often caused by damage to pancreatic beta cells which play a role in secreting insulin in the body. Damage to pancreatic beta cells causes the body to lack insulin. Dipeptidyl peptidase-4 (DPP-4) is a peptidase enzyme complex located on the surface of the cell membrane. Inhibition of the DPP4 enzyme will increase blood GLP-1 levels and induce regeneration of pancreatic beta cells. Senggani leaf (Melastoma malabathricum) boiled water is believed by the people of the Ciamis area to be used as a diabetes medicine. There have been many studies and reviews related to Senggani (Melastoma malabathricum) and its potential. This review focuses on the discussion of Senggani as an antidiabetic by analyzing the reduction in glucose levels and the repair ability of pancreatic beta cells. The results of the literature study that show that senggani leaves have the ability to reduce blood glucose levels and repair activity of pancreatic beta cells through the DPP-4 enzyme inhibition mechanism supported by molecular docking simulation data. There are 12 active compounds that have a binding site similarity above 50% with the comparison compound vildagliptin. Rutin is the best active compound which has a 100% similarity of the binding site. Based on in vivo research and toxicity analysis on the admetsar database, senggani leaf extract and active compounds of senggani leaves have low toxicity, making it safe to be used as antidiabetic herbal preparations.

Published: May 2021

Background: The increase of life expectancy in Indonesia causes increasing numbers of dementia, mostly caused by Alzheimer's disease (AD). High serum cholesterol level has been suggested as a risk factor for AD. The strongest evidence linking lipid profile with AD provided by previous experimental studies where adding or reducing cholesterol altered amyloid precursor protein (APP) and amyloid ?-protein (A?) levels is the basic of this research.

Objective: To determine whether lipid profile is associated with cognitive function deterioration of geriatric outpatients at Neurology Clinic Gunungsitoli Regional General Hospital.

Methods: Participants of this cross-sectional study were outpatient geriatric patients at Neurology Clinic Gunungsitoli Regional General Hospital (n=85; mean age, 62.46±5.49 years old). The cognitive state was evaluated using Montreal Cognitive Assessment Indonesian Version (MoCA-INA) and those with MoCA-INA score <24 were considered cognitively declined. Concentrations of serum lipid profile were measured and correlated with cognitive state using Pearson’s correlation. Multiple logistic regression analysis was used to calculate odds ratios (ORs) for cognitive decline.

Results: Based on Pearson’s correlation test, high-density lipoprotein (HDL) level had significant strong positive correlation with MoCA-INA score (r=0.876;p=0.000) and triglyceride level had significant strong negative correlation with MoCA-INA score (r=-0.726;p=0.000). Relatively to cognitive decline, ORs for decreased HDL level was 3.19 (95%CI 2.02-4.36) and increased triglyceride level was 2.59 (95%CI 1.29-3.91).

Conclusion: There was a significant relationship between decreased HDL-cholesterol level and increased triglyceride level with cognitive decline in geriatric outpatients.
Behavioral and Reproductive Effects of Environmental Enrichment and Pseudoloma neurophilia infection on Adult Zebrafish (Danio rerio)
Authors: Estes Jenny M , Altemara Michelle L , Crim Marcus J , Fletcher Craig A , Whitaker Julia W
Published: May 2021

Recent studies have shown beneficial effects of environmental enrichment (EE) for zebrafish, while infection of zebrafish with the common pathogen Pseudoloma neurophilia has negative effects. This study investigates the effects of P. neurophilia infection and EE in housing
and breeding tanks on measures of behavior, growth, and reproduction. Zebrafish were socially housed and were either infected, P. neurophilia-infected (PNI) (n = 12 tanks), or SPF for P. neurophilia (SPF) (n = 24 tanks). Fish were housed with or without EE, which
consisted of placing plastic plants in the tanks; sprigs from plants were placed in half of the breeding tanks for half of breedings, alternating breeding tanks without EE weekly. Behavioral testing included the Novel Tank Diving Test (NTT) and Light/Dark Preference Test (LDT) conducted prior
to breeding. At the end of the study, biometric data were collected. Histopathology and molecular analysis for common diseases in fish confirmed that SPF fish remained SPF and that fish from all PNI tanks were infected. PNI fish produced significantly fewer eggs and had lower body weights
and lengths than did SPF fish. Fish with EE had longer body lengths, than did fish without EE, and male fish had longer body lengths than female fish. The biometric results and reproductive measures show that SPF fish exhibited better growth and suggest that EE in housing tanks could improve
fish growth. The behavioral test results were inconclusive regard- ing whether infection status or EE altered anxiety-like behavior. Our results support other recent studies showing negative effects of P. neurophilia infection on zebrafish.

Identifikasi Ken Dedes Dalam Arca Perwujudan Sebagai Dewi Prajnaparamita : Tinjauan Filsafat Religi dan Ikonografi
Authors: Suwardono Nfn.
Published: May 2021

Dikalangan masyarakat Malang dan sekitarnya, sosok Ken Dedes (baca: Dedes) sebagai seorang putri Jawa kuno yang dipandang sangat cantik jelita sudah bukan barang baru lagi. Anggapan ini mencuat dipermukaan pada dekade awal abad 19, ketika orang Belanda menemukan reruntuhan di komplek percandian Singosari. Salah satu temuan dari reruntuhan itu adalah sebuah area batu yang sangat indah yang ditemukan di candi Wayang atau candi E (menurut laporan-laporan Belanda), sebuah area dari pantheon agama Budha Mahayana yaitu Dewi Prajnaparamita. Ketika area tersebut untuk sementara berada di tempat residen di Malang, Monnerau, Residen Malang waktu itu menghubungkan area Dewi Prajnaparamita tersebut dengan cerita penduduk tentang Ken Dedes. Dari sinilah dugaan awal timbulnya anggapan bahwa arca Dewi Prajnaparamita adalah portret dari Ken Dedes.

Paradigma pembangunan di banyak negara kini lebih berorientasi kepada pengembangan sektor jasa dan industri, termasuk di dalamnya adalah industri pariwisata. Demikian juga halnya di Indonesia dalam tiga dasawarsa terakhir sektor pariwisata telah didorong dan ditanggapi secara positif oleh pemerintah dengan harapan dapat menggantikan sektor minyak dan gas (migas) yang selama ini menjadi primadona dalam penerimaan devisa negara. Sektor pariwisata memang cukup menjanjikan untuk turut membantu menaikkan cadangan devisa dan secara pragmatis juga mampu meningkatkan pendapatan masyarakat. Situasi nasional yang kini mulai memperlihatkan perkembangan ke arah kestabilan khususnya dalam bidang politik dan keamanan akan memberikan jaminan kepercayaan kepada wisatawan asing untuk masuk ke wilayah Indonesia.

The Multi-fold Theory: A synopsis so far
Authors: Maes Stephane
Published: May 2021

This paper provides a synopsis and review of the multi-fold theory in preparation for more detailed reviews lectures and books. In a multi-fold universe, gravity emerges from Entanglement through the multi-fold mechanisms. As a result, gravity-like effects appear in between entangled particles that they be real or virtual. Long range, massless gravity results from entanglement of massless virtual particles. Entanglement of massive virtual particles leads to massive gravity contributions at very smalls scales. Multi-folds mechanisms also result into a spacetime that is discrete, with a random walk fractal structure and non-commutative geometry that is Lorentz invariant and where spacetime nodes and particles can be modeled with microscopic black holes. All these recover General Relativity (GR) at large scales and semi-classical model remain valid till smaller scale than usually expected. Gravity can therefore be added to the Standard Model resulting into what we defined as SMG. This can contribute to resolving several open issues with the Standard Model without new Physics other than gravity. These considerations hints at a even stronger relationship between gravity and the Standard Model.Among the multi-fold SMG discoveries, the apparition of an-always in-flight, and hence non-interacting, right-handed neutrinos, coupled to the Higgs boson is quite notable. It is supposedly always around right-handed neutrinos, due to chirality flips by gravity of the massless Weyl fermions, induced by 7D space time matter models and hidden behind the Higgs boson or field at the entry points and exit points of the multi-folds. Massless Higgs bosons modeled as minimal microscopic black holes mark concretized spacetime location. They can condensate into Dirac Kerr-Newman soliton Qballs to produce massive and charged particles, thereby providing a microscopic explanation for a Higgs driven inflation, the electroweak symmetry breaking, the Higgs mechanism, the mass acquisition and the chirality of fermions and spacetime; all resulting from the multi-fold gravity electroweak symmetry breaking. The multi-fold theory has also concrete implications on New Physics.We see this paper as a draft to collect comment and feedback as we evolve it towards a fuller publication.

Gas kinetics of galactic disk explains rotation curves of S-type galaxies without a need for Dark Matter.
Authors: Lipovka Anton A.
Published: May 2021

Present work argues that the commonly used methods of classical mechanics cannot be applied to calculate rotation curves for the outer parts of galactic disks, where the influence of collisions in gas on its dynamics becomes dominant. Moreover, the hydrodynamic approach is also not applicable for these purposes due to the extreme rarefaction of the gas. In this case, an alternative approach is developed to describe the dynamics of the rarefied gas in the outer regions of galactic disks, where the gas dynamics is determined mainly by collisions. Equations describing the gas dynamics, but free from the restrictions imposed on hydrodynamics, are derived. The resulting equations relate two quantities: the tangential velocity of the gas as a function of the distance from the galactic center (rotation curve) and the radial distribution of gas density.It is shown that if the physical properties of the rarefied gas are fully taken into account, then dark matter is not required and "non-physical" (non-Keplerian) rotation curves for the outer parts of galactic disks are tailwinds and can be described in the framework of ordinary gas kinetics. To illustrate the legitimacy of the model obtained, two galaxies with flat rotation curves (NGC7331 and NGC3198) are considered. From the given rotation curves, a good agreement was obtained between the gas densities calculated by expression (14) and their observed values. This coincidence is an additional argument in favor of the considered model.. Thus, the nonphysical rotation curves of spiral galaxies are tailwinds of gas, the dynamics of which should be described by kinetic equation, without involving the concept of dark matter. The total masses of the galaxies NGC7331 and NGC3198 have been calculated. The implications for cosmology are discussed.

Misbegotten Methodologies and Forgotten Lessons from Tom Swift’s Electric Factor Analysis Machine: A Demonstration with Competing Structural Models of Psychopathology
Authors: Greene Ashley Lauren , Watts Ashley L. , Forbes Miriam K. , Kotov Roman , Krueger Robert , Eaton Nicholas R
Published: May 2021

Confirmatory factor analysis (CFA) and its bifactor models are popular in empirical investigations of the factor structure of psychological constructs. CFA offers straightforward hypothesis testing but has notable pitfalls, such as the imposition of strict assumptions (i.e., simple structure) that obscure unmodeled complexity. Due to the limitations of bifactor CFAs, they have yielded anomalous results across samples and studies that suggest model misspecification (e.g., evaporating specific factors and unexpected loadings). We propose the use of exploratory factor analysis (EFA) to evaluate the structural validity of CFA solutions—either before or after the estimation of more restrictive CFA models—to (1) identify model misspecifications that may drive anomalous estimates and (2) confirm CFA models by examining whether hypothesized structures emerge with limited researcher input. We evaluated the degree to which predominant factor structures were invariant across contexts along the exploratory-confirmatory continuum and demonstrate how poor methodological choices can distort results and impede theory development. All models fit well, but there were numerous differences in replicability and substantive interpretability. Several similarities emerged between bifactor CFA and EFA models, including evidence of overextraction, the collapse of specific factors onto the general factor, and subsequent shifts in how the general factor was defined. We situate these methodological shortcomings within the broader literature on structural models of psychopathology, articulate implications for theories (such as the p-factor) that are borne out of factor analysis, outline several remedies for problems encountered when performing exploratory bifactor analysis, and propose alternative specifications for confirmatory bifactor models.
Remembering for Resilience: Brief Cognitive-Reminiscence Therapy Improves Psychological Resources and Mental Well-Being in Young Adults

Published: May 2021

Reminiscence-based interventions focus on the recall of autobiographical memories and reflective reasoning about these remembered experiences. This study assessed the effect of a three-session, positive-memory version of cognitive-reminiscence therapy (CRT) on the psychological resources and mental well-being of young adults. The participants (N=62, Mage=24.6 [SD=3.1], 71% females) were randomised to CRT or wait-list. Psychological resources (self-esteem, self-efficacy, meaning in life, optimism), mental well-being (depression, anxiety, and stress symptoms) and theorised change processes (automatic negative thoughts, awareness of narrative identity and cognitive reappraisal) were assessed. The results showed the CRT group was significantly higher on psychological resources at post-CRT (d=0.75-0.80) and follow-up (d=0.52-0.87), and mental well-being at post-intervention (d=0.71–1.30) and follow-up (d=0.64–0.98). The hypotheses regarding change processes were supported. Future research may use an active comparator and include a longer follow-up, given only short-term effects were assessed. Brief, positive-focused CRT is effective in increasing psychological resources and mental well-being in young adults.
High reliability knowledge networks: Responding to animal diseases in a pastoral area of northern Kenya
Authors: Tasker Alex , Scoones Ian
Published: May 2021

How can reliability be generated and sustained in the face of uncertainty? This question is explored by examining knowledge networks among pastoralists and others in northern Kenya, emerging in response to a highly variable animal disease setting. Using quantitative and qualitative social network analysis, intersecting locally-embedded, development project and political networks are identified. Drawing on high-reliability theory, as applied to critical infrastructures, the paper explores the key characteristics of the knowledge networks in relation to systems, knowledges, relationships, technologies, professionals and politics. Reliability – the ability to provide stable services and respond variability in real-time – is shown to be related to the networked capacity to mobilise knowledge to confront uncertainty and avoid ignorance, with certain high-reliability professionals central. The locally-embedded network in particular has important characteristics of a high reliability knowledge network, but key brokers link to the development project and political network. Development challenges often require addressing uncertainty and even ignorance and lessons from high-reliability approaches can be crucial.
Quantifying The Effect of Wakefield et al. (1998) on Skepticism about MMR Vaccine Safety in the U.S.
Authors: Motta Matt , Stecula Dominik
Published: May 2021

Background. Efforts to trace the rise of childhood vaccine safety concerns in the US often suggest Andrew Wakefield and colleagues’ retracted 1998 Lancet study (AW98) – which alleged that the MMR vaccine can cause children to develop autism – as a primary cause of US vaccine skepticism. However, a lack of public opinion data on MMR safety collected before/after AW98’s publication obscures whether anecdotal accounts are indicative of a potentially-causal effect. Methods. We address this problem using a regression discontinuity framework to study change in monthly MMR injury claims (N = 74,850; from 1990-2019) from the Vaccine Adverse Events Reporting System (VAERS) to proxy concern about vaccine safety. Additionally, we suggest a potential mechanism for the effect of AW98 on vaccine skepticism, via automated sentiment analyses of MMR-related news stories (N = 674; from 1996-2000) in major television and newspaper outlets. Results. AW98 led to an immediate increase of about 70 MMR injury claims cases per month, averaging across six estimation strategies (meta-analytic effect = 70.44 [52.19, 88.75], p < 0.01). Preliminary evidence suggests that the volume of negative media attention to MMR increased in the weeks following AW98’s publication, across four estimation strategies (meta-analytic effect = 9.59% [3.66, 15.51], p < 0.01).Conclusions. Vaccine skepticism increased following the publication of AW98, which was potentially made possible by increased negative media coverage of MMR. Significance. Childhood vaccine skepticism presents an important challenge to widespread vaccine uptake, and undermines support for pro-vaccine health policies. In addition to advancing our understanding of the previously-obscured origins of US vaccine skepticism, our work cautions that high-profile media attention to inaccurate scientific studies can undermine public confidence in vaccines. We conclude by offering several recommendations that researchers and health communicators might consider to detect and address future threats to vaccine confidence.
Moral Reframing Increases Support for Economically Progressive Candidates

While most Americans perceive current levels of inequality in the US as too high, economically progressive candidates who champion redistributive policies designed to reduce inequality rarely win elections. Here we propose that progressive candidates achieve greater support by framing their policy platforms in terms of values that resonate beyond their progressive base. In two experiments (total N = 4,138), including one pre-registered experiment conducted on a national probability sample, we found that a presidential candidate who framed his progressive economic platform using values consistent with the “binding” moral foundations – e.g., patriotism, family, and respect for tradition – as opposed to values consistent with the “individualizing” foundations – e.g., equality and social justice – received significantly stronger support. This effect was driven by increased support among conservatives and, unexpectedly, among moderates as well. By comparison, a manipulation of how progressive the candidate’s platform was had small and inconsistent effects. Despite the potential gains associated with binding framing, analyses using (a) text-based analysis of every word spoken in a presidential debate since 2000, and (b) machine learning-based measures of recent presidential candidates’ economic views, reveal that appeals to binding values are least common among economically progressive candidates. These findings show, however, that the alignment between values and economic policies is malleable, suggesting economically progressive candidates can build broader coalitions by reframing the values they associate with their platforms.
Greater Diversity or Fewer Whites? Disentangling Heterogeneity and Marginalized Group Share at Macro and Micro Levels
Authors: Abascal Maria , Ganter Flavien , Baldassarri Delia
Published: May 2021

Scholarship claims that diversity undermines trust and cooperation. Critiques focus on studies' inability to discern diversity's causal effects. In fact, most studies are unable to distinguish diversity (i.e., mixture) and marginalized group share (e.g., percentage Black). We argue for preserving this distinction and identify obstacles to doing so. First, homogeneously disadvantaged communities are acutely underrepresented in North America and Europe, the settings of most diversity research. The second issue, a case of the ecological fallacy, concerns our inability to infer associations between individual outcomes and diversity from associations between macro-level outcomes and diversity. Much diversity research would be better served by using group share measures that align with the ingroup/outgroup theories they draw on to motivate research and explain findings. We clarify the data and analytic requirements for research that seeks to draw conclusions about diversity per se. Practically, the distinction between diversity and marginalized group share is also relevant for policy.
A Discussion of John Keats’s Ode to a Nightingale
Authors: Khadka Kul Bahadur
Published: May 2021

John Keats passes away at an early age but leaves many outstanding works behind. In his Ode to a Nightingale, the poet sees suffering on the earth and highly appreciates a nightingale’s marvelous music. This article discusses the pain-pleasure contrast and association in terms of the poet and the nightingale. It also explores the use of time and space in the poem. It is important to know where and when the bird is singing and the poet is sitting, listening to the bird’s music. The use of imagery ad symbols in the poem is very significant to connect the poet’s world with that of the bird. Art, death and life can be drawn as major themes in the poem. In order to strengthen the discussion, various books and critics’ opinions concerning Keats, the respective poem and Romanticism have been consulted. The discussion reveals the poet’s ugly and painful world which is real and the nightingale’s beautiful and pleasurable world which is ideal. The real contrasts from the ideal and sometimes they get associated with each other. In exclusion of the ideal, the real suffers and gets confused.
An Alternative Reading of Amor Towles’s A Gentleman in Moscow
Authors: Acharya Rajendra
Published: May 2021

This paper explores Amor Towles’s A Gentleman in Moscow (2016) as an Alternative Reading of Stalinian Era in terms of its reinterpretation of the Russian history and scrutinization of the historical documents. In doing so, this paper endeavors to study Amor Towles’s A Gentleman in Moscow (2016), through the vantage point of Foucauldian discourse supported by Friedrich Nietzsche’s notion of ‘freewill’, Catherine Gallaher and Stephen Greenblatt’s notion of ‘counter history.  This Article further delves in to the official history and examines the power-politics of and behind the critique of Stalinian regime by observing the socio-cultural background of the author. The paper also offers more than one potential reading of Russian history and the novelist’s social context in order to analyze the novel as a direct outcome of the clashing interpretations and concludes that, Towles, while crafting historical fiction, explicitly tantalizes Russian history, implicitly emphasizes American values and creates the new knowledge for the sake of subjugated through artistic discourse. Finally, the paper will demonstrate that the novelist invites the reader to concentrate and support the political power of marginalized group despite its absence in official history.
Niewypowiedziane naruszenia więzi i emocji, czyli o kryzysach zapisanych w ciele. Znaczenie choreoterapii w redukcji napięć emocjonalnych
Authors: Pyrzyk-Kuta Aleksandra
Published: May 2021

W artykule podjęto temat cielesnych aspektów kryzysu emocji i kryzysu więzi. Rozważania opierają się na socjologicznej teorii emocji Thomasa J. Scheffa oraz Suzanne Retzinger, którzy podkreślali znaczenie więzi społecznych w rozwiązywaniu konfliktów i radzeniu sobie z trudnościami. Każda odczuwana emocja ma swój odpowiednik motoryczny w ciele, które pamięta traumatyczne doświadczenie oraz, szeroko rozumiane, konflikty i wynikające z nich obciążenia. Gdy nagromadzone emocje nie znajdują ujścia, ciało może chorować. Aby temu zapobiec, istotne są interwencje psychologiczne z równoległą pracą na poziomie ciała. Studia przypadków, które są ważną częścią opracowania, ukazują, w jaki sposób – poprzez choreoterapię i czynniki leczące – kryzysowość zmienia znaczenie, a napięcia emocjonalne minimalizują się.
Do Legitimate Publishers Benefit or Profit from Error, Misconduct or Fraud?
Authors: Teixeira da Silva Jaime , Vuong Quan-Hoang
Published: May 2021

One of the aspects of post-publication peer review that is difficult for reputable journals or publishers to accept is that it may reveal flaws in their oft-claimed resilient peer review and efficient editorial management. Prospective authors are frequently sold a brand-associated image of a fail-safe process, rigorous editorial handling, and stringent peer review. Yet, in reality, a sector of the published literature that has passed through claimed rigorous screening may still be flawed and contain errors, while some of the peer-reviewed literature is the product of fraud or misconduct. Even top-ranked journals, in terms of journal-based metrics such as the Clarivate Analytics’ journal impact factor, or those that are indexed or hosted on platforms like PubMed, Scopus or Web of Science, have published papers with associated errata or retractions. In such journals, it is possible that erroneous literature has yet to be detected. This paper argues that publishers draw benefit in the form of metrics-based recognition, such as citations to erroneous or retracted papers, or financial reward, either as subscription fees or in the form of article processing charges, neither of which is refunded when a peer-reviewed academic paper is retracted. Knowing that peer review and editorial decisions can be imperfect, publishers have a moral responsibility of toning down claims of the excellence or perfection of peer review when advertising their journals, or they should conduct a full-scale post-publication peer review of their journals’ entire collection to prove it. In turn, academics need to be more proactive in the publishing ecosystem, seeking to correct the literature when errors are found, and not be afraid to call out editors or publishers that defy their claimed academic or ethical excellence.

The spread of COVID-19 has forced many people around the world to adjust the manner in which they relate to and participate in the goings-on of the outside world. This article examines a seemingly novel attempt by a few amateur investors to take on the might of hedge funds’ cutting-edge algorithms. Our analysis includes an examination of short-selling, online investment communities and the problem of collective action they face. This piece examines how Wall Street betters on Reddit, with little or no experience, brought a new series of questions about regulation and speculative investing to the fore. We close by reflecting on the kinds of questions that people who are interested in the stock market (no matter their ability) might ask themselves in the very near future.

Published: May 2021

The present paper describes the implementation of electrospinning technique to manufacture (polymeric-nonwoven) fibrous-mats (with micrometric/nanometric fibers) as photosensitive region. These mats are tailored and assembled in UV-A radiation detection cards.  The selective photoluminescence of our mats is due to the Europium ions (Eu3+, Eu+2) added as Europium nitrate to a polymethyl methacrylate (PMMA) matrix. The electrospinning-equipment operation-parameters such as applied voltage (10 kV), distance from needle tip to collector plate (17 cm), and precursor-solution flow-rate (0.45 mL/h) are determined from the solution of a unidimensional model comprising three differential equations. The manufactured photoluminescent mats average-fiber-diameter is 1.3 ± 0.5 mm, with 76% void volume, average void-size of 7 mm, and average thickness of 350 mm. The photoluminescent mats sustain significant light absorption in the wavelength range of 245 to 350 nm and corresponding emission in the visible range of 400 to 650 nm.
