Published: June 2021

The experiment was performed at a non-acclimatized protected screened environment. The objective of the study was to evaluate the influence predecessor crops of single and intercropping corn and brachiaria on soybean yield submitted to irrigation intervals. The experimental design adopted was in a split split-plot randomized block design with four repetitions. Two soil classes (dystroferric Red Latosol and dystrophic Red Latosol) were evaluated in the plots, three intervals between irrigations were used during the soybean flowering (each one day, two days and three days) in the subplots and three types straw in the crops autumn-winter (single corn, single brachiaria, intercropping corn and brachiaria) in the sub-subplots. The two soybean plants cultivated in polyethylene pots containing 20 liters of dystroferric Red Latosol or dystrophic Red Latosol corresponded to each repetition, according to the treatment. The irrigation intervals of three and two days, in dystroferric Red Latosol and dystrophic Red Latosol, respectively, with single brachiaria at the previous crop provided greater number and weight of pods, higher number of grains and higher soybean yield. Irrigation every three days with single corn at the previous crop in dystroferric Red Latosol and dystrophic Red Latosol, resulted in the lower soybean performance.
Local politicians in action? The relationship between perceived prerequisites and actions of political committees responsible for social services in supporting the implementation of evidence-based practice
Authors: Bäck Annika , von Thiele Schwarz Ulrica , Bergström Anna , Hasson Henna , Richter Anne
Published: June 2021

Background:

A supportive context is essential for successful implementation processes. Local politicians are delivery system actors who might both enable and hinder the implementation of health and social policies.

Aims and objectives:

The study examines the relationship between perceived prerequisites and the type of actions taken by local political committees to support the implementation of evidence-based practice in social services.

Methods:

A cross-sectional web survey targeting the chair and vice-chair of committees responsible for social services in Sweden (n=181). The data was analysed with regression analysis, cluster analysis and ANOVA.

Findings:

Three clusters of action were identified (passive, neutral and active), capturing the reported actions taken by the committees to support implementation of EBP. The committees’ perceived prerequisites (capability, motivation, and opportunity) were highest in the active cluster and lowest in the passive cluster. The clusters also differed regarding chair/vice-chair educational level, and type of municipality in which the chair/vice-chair were active.

Discussions and conclusion:

The variation in reported actions among the committees to support the implementation of EBP implies that some social service organisations might lack the contextual support they need for implementing EBP. The prerequisites for the committees might need to be strengthened with regard to capability, motivation and opportunity. This study is an indication of the relationship between committees’ prerequisites and their actions in the implementation of EBP, but further research is needed.

Published: June 2021

The purpose of the present study is to predict the whole chromatic path traveled by the colors of glossy anodized titanium samples in every specular geometry. It is based on measurements of the samples’ reflectance spectra in a limited number of specular geometries, which allow us to obtain the oxide layer structural parameters (thickness, refractive index), which are then put into an optical model to predict the samples' reflectance spectra in every specular geometry. A good color prediction performance is obtained, with an average

Quantum memories and the double-slit experiment: implications for astronomical interferometry
Authors: Bland-Hawthorn Joss , Sellars Matthew J. , Bartholomew John G.
Published: June 2021

Thomas Young’s slit experiment lies at the heart of classical interference and quantum mechanics. Over the last 50 years, it has been shown that particles (e.g., photons, electrons, large molecules), even individual particles, generate an interference pattern at a distant screen after passage through a double slit, thereby demonstrating wave-particle duality. We revisit this famous experiment by replacing both slits with single-mode fiber inputs to two independent quantum memories that are capable of storing the incident electromagnetic field’s amplitude and phase as a function of time. At a later time, the action is reversed: the quantum memories are read out in synchrony, and the single-mode fiber outputs are allowed to interact, consistent with the original observation. In contrast to any classical memory device, the write and read processes of a quantum memory are non-destructive and hence preserve the photonic quantum states. In principle, with sufficiently long storage times and sufficiently high photonic storage capacity, quantum memories operating at widely separated telescopes can be brought together to achieve optical interferometry over arbitrarily long baselines.
Investigating the trade-off between color saturation and angle-independence in photonic glasses

Published: June 2021

Photonic glasses—isotropic structures with short-range correlations—can produce structural colors with little angle-dependence, making them an alternative to dyes in applications such as cosmetics, coatings, and displays. However, the low angle-dependence is often accompanied by low color saturation. To investigate how the short-range correlations affect the trade-off between saturation and angle-independence, we vary the structure factor and use a Monte Carlo model of multiple scattering to investigate the resulting optical properties. We use structure factors derived from analytical models and calculated from simulations of disordered sphere packings. We show that the trade-off is controlled by the first peak of the structure factor. It is possible to break the trade-off by tuning the width of this peak and controlling the sample thickness. Practically, this result shows that the protocol used to pack particles into a photonic glass is important to the optical properties.
Point to multi-point physical-layer key generation and distribution in passive optical networks
Authors: Zhang Liuming , Huang Xinran , Hu Weisheng , Yang Xuelin
Published: June 2021

A point to multi-point physical-layer secure key generation and distribution (SKGD) scheme is proposed and demonstrated in passive optical networks (PONs), where the optical line terminal (OLT) broadcasts optical lights with fast fluctuating states of polarization (SOPs) to the optical network units (ONUs). The highly correlated key waveforms are shared between OLT and ONUs, and the high-level security of the SKGD scheme is guaranteed by the high sensitivity of SOP dynamics associated with the specific fiber links. As a proof of concept, a 3.9 Gb/s SKGD is achieved over 11 km single-mode fiber, where a Sagnac interferometer-based polarization scrambler is constructed as the high-speed random source. Moreover, the generated key sequences are verified to be error free and truly random. The proposed SKGD scheme offers a flexible solution for security enhancement in PONs, and is also compatible with the current PON infrastructure.

Published: June 2021

Polarization is a significant factor in a great variety of optical phenomena, playing an important role in determining the focusing properties of lenses, in the resolution of optical systems, and in the performance during laser processing. Knowing the polarization distribution in focused light is critical to understanding and designing relevant optical devices and systems. However, it remains challenging to characterize the vectorial polarization distribution in optical fields. We develop a polarization-conversion-based optical microscope for directly acquiring the distribution of three orthogonal polarizations in focused light and theoretically prove and experimentally demonstrate its validity by characterizing super-resolution focused light with different incident polarizations.
The temporal evolution of income polarization in Canada’s largest CMAs
Authors: Ilic Lazar , Sawada M.
Published: June 2021

Income polarization is a pressing issue which is increasingly discussed by academics and policymakers. The present research examines income polarization in Canada’s eight largest Census Metropolitan Areas (CMAs) using data at the census-tract (CT) level between 1971 and 2016. Generally, there are significant decreasing trends in the middle-income population with simultaneously increasing trends in low-income groups. The high-income groups have been relatively stable with fewer significant increasing population trends. Using conventional mapping and cartograms, patterns of the spatial evolution of income inequality are illustrated. Every CMA examined contains an increasing trend of spatial fragmentation at the patch level within each CMA’s landscape mosaic. The results of a spatial autocorrelation analysis at the sub-patch, CT level, exhibit significant spatial clustering of high-income CTs as one process that dominates the increasingly fragmented landscape mosaic.

Published: June 2021

Objective

To investigate the association between the nuclear factor kappa B (NF-kB) gene polymorphism and age-related macular degeneration (AMD) in a high-altitude population.

Methods

Fifty-five patients with AMD and 57 control subjects were recruited from the Qinghai Provincial People’s Hospital, China. Genomic DNA was extracted from the blood sample of each participant. FourNF-kBpolymorphisms (rs3774959, rs3774932, rs3774937, and rs230526) were genotyped using a MassARRAY system. The genotype and allele frequencies were compared between the case and control groups using the chi-squared test or Fisher’s exact test.

Results

There was no significant difference in sex, age, hypertension, diabetes, blood lipid level or smoking and drinking status between the AMD and control groups (P> 0.05). The genotype distributions of fourNF-kBpolymorphisms were in accordance with Hardy-Weinberg equilibrium in the control group (P> 0.05). The frequencies of genotype AA of rs3774932 and genotype CC of rs3774937 were nominally significantly higher in the AMD group than in the control group (P= 0.046 and 0.023, respectively), although these associations did not survive the Bonferroni correction (correctedP> 0.05). Genotype distributions of rs3774959 and rs230526 were not significantly different between the two groups (P= 0.08 and 0.16, respectively). No significant difference in the allele frequencies of the four polymorphisms was found between the AMD and control groups (P> 0.05).

Conclusions

Genotype AA of rs3774932 and genotype CC of rs3774937 inNF-kBmight be risk factors for AMD.

Published: June 2021

Background

The distribution of body mass in populations of Western countries differs from that of populations of East Asian countries. In East Asian countries, fewer people have a high body mass index than those in Western countries. In Japan, the country with the highest number of older adults worldwide, many people have a low body mass index. Therefore, this study aimed to determine the association between a low body mass index and mortality in patients with sepsis in Japan.

Methods

We conducted this retrospective analysis of 548 patients with severe sepsis from a multicenter prospective observational study. Multivariate logistic regression analyses determined the association between body mass index and 28-day mortality adjusted for age, sex, pre-existing conditions, the occurrence of septic shock, Acute Physiology and Chronic Health Evaluation II scores, and Sequential Organ Failure Assessment scores. Furthermore, the association between a low body mass index and 28-day mortality was analyzed.

Results

The low body mass index group represented 18.8% of the study population (103/548); the normal body mass index group, 57.3% (314/548); and the high body mass index group, 23.9% (131/548), with the 28-day mortality rates being 21.4% (22/103), 11.2% (35/314), and 14.5% (19/131), respectively. In the low body mass index group, the crude and adjusted odds ratios (95% confidence intervals) for 28-day mortality relative to the non-low body mass index (normal and high body mass index groups combined) group were 2.0 (1.1–3.4) and 2.3 (1.2–4.2), respectively.

Conclusion

A low body mass index was found to be associated with a higher 28-day mortality than the non-low body mass index in patients with sepsis in Japan. Given that older adults often have a low body mass index, these patients should be monitored closely to reduce the occurrence of negative outcomes.
The rise of the policy-takers: Universal service policy adoption in Jordan and Morocco
Authors: Wavre Veronique
Published: June 2021

In the late 1990s, Jordan and Morocco revised their telecommunications regulation drastically. Though these regulations were first largely inspired by the European Union policy models, each country gradually developed more autonomy, individually tailoring their regulatory frameworks overtime. The case of Universal Service Obligation (USO) policies show that while Jordan remained aligned with the European Union, Moroccan policy-makers diverged from the European Union by adopting alternative policies, inspired by the Latin American reverse-auction models. Research focusing on Euro-Mediterranean regulatory contexts commonly expect neighbouring countries to converge with EU regulatory models. Yet, borrowing on policy diffusion literature and specifically the mechanisms of learning and imitation, this article shows that policy-takers intentionally decided on the (non)adoption of USO policies. Thus, research needs to take the role of policy-takers seriously and acknowledge avenues for bidirectional convergence.
Towards Indonesia’s integrated broadcast-broadband implementation policy: A comparative analysis of Singapore, Japan and Malaysia
Authors: Yuniarti Diah , Ariyanti Sri
Published: June 2021

This study aims to provide recommendations to the government on regulating licence, content and data privacy and protection for integrated broadcast-broadband (IBB) operations in Indonesia, by referencing Singapore, Japan and Malaysia as case studies, considering the need for umbrella regulations for IBB implementation. Singapore and Japan were chosen as countries that have deployed IBB since they have been using hybrid broadcast broadband television (HbbTV) and Hybridcast standards, respectively. Malaysia was chosen because it is a neighbouring country that has conducted trials of the IBB service, bundled with its digital terrestrial television (DTT) service. The qualitative data are analysed using a comparative method. The results show that Indonesia needs to immediately revise its existing Broadcasting Law to accommodate DTT implementation, which is the basis for IBB and the expansion of the broadcaster’s TV business. Learning from Singapore, Indonesia could include over-the-top (OTT) content in its ‘Broadcast Behaviour Guidelines’ and ‘Broadcast Programme Standards’. Data privacy and protection requirements for each entity involved in the IBB ecosystem are necessary due to the vulnerability of IBB service user data leakage. In light of this, the ratification of the personal data protection law, as a legal umbrella, needs to be accelerated.
Babits – Dosztojevszkijről
Authors: Nagy István
Published: June 2021

Ezt az írást a katolikus Pilinszky János soraival kezdem. Ugyan a Szög és olaj esszéi – köztük a csaknem harminc Dosztojevszkijre való hivatkozás – a hatvanas-hetvenes években íródtak, s ezért nem illeszkedhetnek abba a képbe, melyet a két világháború között magyarul írtak, magyar szerzők Dosztojevszkijről. Ha mégis Pilinszky felől közelítek Babits Dosztojevszkij-olvasatához, az több szempontból is indokolt. Úgy vélem, hogy a Pilinszky által is kulcsszónak tekinthető „vallomásirodalom” az a fogalom, amely az emberi sors „mélyrétege”, a „világ abszurditása” iránt oly érzékeny Dosztojevszkijre maradéktalanul ráillik.1 Az egyre aggasztóbb háborús helyzet a beteg Babitsot morális szerepvállalásra készteti, ahogyan Pilinszky írja róla: „Többé nem húzódhatott vissza a merő esztétikumba, a gyülekező veszély vallásos és morális szerepre, vallomásra kényszerítette.” (Pilinszky, 1982. 39.).2 Pilinszkynél olvassuk az alábbi, Dosztojevszkij felé mutató megjegyzést is. „Az európai irodalomról Babits Mihály írta meg, hogy lényege szerint gyónás, vagyis vallomásirodalom.” (Pilinszky, 1982. 238.) Babits „vallomástartalmú, vallomáscentrikus” irodalom iránti vonzódása lehet magyarázat Dosztojevszkij-olvasatára is.
Dosztojevszkij hatása Pilinszky János kárhozatról szóló elmélkedéseiben
Authors: Kontra Attila
Published: June 2021

Jean-Paul Sartre Férfikor című regényére reflektáló esszéjében Pilinszky (1999. 118–119.) a következőket írja: „A pokol titka: a semmi titka, az élet örömeinek és szenvedéseinek megtagadása. A mennyek titka viszont a szeretet titka. Az élet örömeinek és szenvedéseinek vállalása. A semmi titkával a teremtés titka, a megsemmisülés titkával a szereteté áll szemben. Legszebb modern ábrázolását e küzdelemnek Dosztojevszkij írta meg a Karamazov testvérekben-ben, a rejtélyesen elmagányosodott Iván és a titokzatosan nyitott Aljosa ellentétében. Iván körül a semmi művei és tettei, amelyek mindig többet mutatnak, mint a mögöttük tátongó üresség, míg Aljosa igénytelen s alázatos cselekedetei mögött a hatalmas és kifogyhatatlan többlet hallgat, mintha a teremtés egyedül a szeretetben válna érvényessé, bírná és kívánná csak igazán megvalósítani, betetőzni önmagát. Szeretet híján a valóság a semmibe hanyatlik vissza.”

Published: June 2021

Objective. To assess the correctness of transpedicular screw insertion in thoracic and lumbar vertebrae using two-level navigation templates for narrow pedicles.

Material and Methods. Two-level navigation templates were used in surgical treatment of four patients aged 14–17 years with scoliotic deformity and multiple pedicles of small width (less than 4.35 mm). In each patient, the least favorable zones were selected for implantation using navigation templates. The rest of planned pedicle screws were inserted using free-hand technique. All patients underwent CT scanning postoperatively. Screws inserted to pedicles less than 4.35 mm in width  were classified as correctly placed if they did not extend beyond the medial cortical layer by more than 2 mm.

Results. Out of 68 pedicles planned for screw placement, 42 were narrower than 4.35 mm. In the pedicles difficult for implantation, 29 screws were inserted using navigation templates and 13 by free-hand technique. Screws classified as correctly placed were 28 from those inserted with navigation templates and 9 from those implanted by free-hand technique. Difference in results of screw placement in narrow pedicles with navigation templates and by free-hand technique was statistically significant (exact Fisher test, p < 0.05).

Conclusion. Transpedicular screw placement with two-level navigation templates in narrow pedicles is more correct than insertion by free hand technique.

Published: June 2021

Objective. To analyze surgical technique and possibilities of using bilateral laminoplasty technique with simultaneous foraminotomy for extended stenosis of the cervical spine.

Material and Methods. The analysis included results of surgical treatment of 26 patients (18 males and 8 females, mean age 60.2 ± 1.3 years) operated on by the method of bilateral laminoplasty with simultaneous foraminotomy from January 2016 to April 2020. Pre- and postoperative clinical condition of patients was assessed, including using VAS, JOA and Nurick scales. An objective assessment of stenosis degree (linear dimensions, areas, volume of the stenotic spinal canal) was performed using standard measuring tools of the RadiAnt DICOM Viewer software. To assess the statistical significance of the obtained results, nonparametric Wilcoxon-T and Mann – Whitney-U tests were used. Differences were considered significant at p < 0.05.

Results. Upon admission to the hospital, all patients had specific neurological symptoms with varying degree of pain, myelopathic and radicular symptoms. According to neurovisualisation, the average number of involved in the process levels (stenotic) was 3.2 ± 0.1, (the average length of stenosis was 5.1 ± 0.2 cm). In the postoperative period, all patients showed positive dynamics in the form of a decrease in the severity of neurological disorders and pain (from 7.2 ± 0.1 to 5.07 ± 0.1 according to VAS, p < 0.001). The manifestations of myelopathy decreased according to Nurick scale from 2.08 ± 0.71 to 1.84 ± 0.10 points (p < 0.05). According to MRI data, the average area of the dural sac objectively increased from 1.25 ± 0.30 cm2 to 2.26 ± 0.27 cm2 (p < 0.001), and the volume of spinal canal in the area of stenosis increased from 7.2 ± 0.2 cm3 to 13.4 ± 0.1 cm3 (p < 0.001). Patients were mobilized on the 2nd day after surgery. The duration of inpatient treatment ranged from 4 to 17 days (on average, 7.1 ± 0.4 days). Intraoperative complications were not observed in the presented series. Mild postoperative complications were detected only in two out of 26 operated patients.

Conclusion. Bilateral laminoplasty with simultaneous foraminotomy using titanium miniplates and osteoinductive material has a number of advantages and can be the surgery of choice in the treatment of patients with extended cervical stenosis complicated by myelopathy and radicular pain syndrome.

The paper is a review of the current literature data on the use of various materials and drugs for the prevention of the development of postoperative lumbar epidural fibrosis. Literature searches were performed in the Pubmed, Medline, EMBASE, Cochrane Library and eLibrary databases. The formation and growth of fibrous tissue in the epidural space, followed by tissue adhesion to the dura mater, is the leading cause of pain afferentation in the lumbar spine and/or lower extremities. Several molecular and cellular mechanisms play an important role in the pathophysiology of connective tissue formation in the epidural space. An analysis of experimental and clinical studies examining the effectiveness of various materials and drugs is presented. The authors present the current data on new therapeutic approaches to the prevention of postoperative epidural fibrosis. Topical, unresolved issues which necessitate further research on the pathophysiology of epidural fibrosis are indicated.

Being considered equal to normal people in general is a dream that people with disa-bilities really want to realize. The public's view of disability has constructed the stig-ma that people with disabilities are unable to move like normal people specifically relating to physical exercise.. The difficulty of dismantling the stigma that is already inherent and generalizing persons with disabilities with physical disability or mal-function becomes a particular challenge faced by persons with disabilities as a mi-nority group. This paper uses the constructivist paradigm as a point of view in look-ing at understanding the complexity of social construction. The phenomenological method used in this study will explore the perspective of individuals with disabilities through self-concept "me" as an object that is the result of community construction, try to be replaced with "I" as a subject that is reconstructed through the help of so-cial media with self-actualization amid physical limitations which is owned. This study found that messages through social media that contain hopes and big dreams which imply that people with disabilities also have physical abilities and expertise equivalent to normal people in general. Various attempts were made, even more so by utilizing social media as a means of proving to the world about "This Is Me"and “I Can Do Anything

Published: June 2021

The popularity of puppets and batik in the eyes of teenagers, especially Javanese people, is already inferior to fictional Hollywood superhero figures such as Hulk, Superman, Batman, Ironman, Spiderman, and other Avenger. On the other hand, we actually have a wealth of traditional art forms that are very rich in philosophical values and unmatched artistic techniques. However, nowadays, youth's pride in the nation's art works seems fragile and easily outdated, being replaced by an external art culture that is full of modernity and relatively superficial in value. The redesign of the wayang cakrik batik from the wayang kulit reference object is an effort to strengthen the national identity of the youth, while at the same time offering a solution so that the youth will love and be proud of the art of their ancestral heritage. This survey research with a quantitative descriptive approach seeks to evaluate and capture the responses of adolescents as the main target audience regarding the redesign of this batik cakrik puppet so that it fosters the enthusiasm of the teenagers. As a result, the teenagers received well the works of wayang cakrik batik from various aspects that were important to observe, namely mainly with the visual communication design approach. A process that is no less important after this research is the development and refinement of the redesign of the batik cakrik wayang by considering the audience's response.
Visible-light-induced peroxymonosulfate activation over ZnFe2O4 fine nanoparticles for ofloxacin degradation

Published: June 2021

Widespread overuse and misuse of antibiotics has led to unintended consequences, and it is necessary to find effective ways to remove antibiotics. In this study, a visible-light-response photocatalyst zinc ferrite (ZnFe2O4) was synthesized via a hydrothermal method. Meanwhile, the X-ray diffraction, Brunauer–Emmett–Teller, scanning electron microscope, X-ray photoelectron spectroscopy, and Fourier transform infrared spectra analysis were applied to characterize the structure, morphology, and physicochemical properties of the ZnFe2O4. The results indicated that the ZnFe2O4 was circular granular morphology with a particle size of approximately 30–50 nm and the noticeable intergranular agglomeration. The specific surface area, pore volume, and pore diameter of the ZnFe2O4 were determined to be 126.8655 m2/g, 0.2046 cm3/g, and 64.5190 Å, respectively, representing that the ZnFe2O4 had a large specific surface area. Moreover, the enhancement of degradation efficiency of ofloxacin (OFL) by peroxymonosulfate (PMS) under the visible light (Vis) was systematically evaluated. The results exhibited that the ZnFe2O4 achieved the relatively optimum catalytic activity with 80.9% of OFL degradation efficiency in 30 min at pH 6.0 under the PMS concentration of 100 mg/L and the corresponding pseudo-first-order kinetic constant of OFL degradation was 0.0438 min–1. In addition, the effects of ZnFe2O4 dosage, PMS concentration, initial OFL concentration, solution pH, and water matrix on the OFL degradation were comprehensively investigated in the Vis/PMS/ZnFe2O4 process. Furthermore, the ZnFe2O4 exhibited excellent stability and reusability for OFL degradation. The Vis/PMS/ZnFe2O4 process would be a reliable alternative for the degradation of OFL-like antibiotics to solve the increasingly serious problem of antibiotic pollution.
Characterizing detection probabilities of advanced mobile leak surveys
Authors: Luetschwager Emily , von Fischer Joseph C. , Weller Zachary D.
Published: June 2021

Advanced leak detection (ALD) to survey local natural gas distribution systems has reached a point in technological maturity where new federal regulations will require its use in compliance surveys. Because most of these deployments are conducted by commercial providers, there has been little publicly available data documenting characteristics of the underlying methane (CH4) plumes that are the core features measured in ALD surveys. Here, we document key features of CH4 plumes measured in ALD surveys of 15 U.S. metropolitan areas where we had deployed high-sensitivity CH4 analyzers on Google Street View cars. Our analysis reveals that CH4 concentration enhancements from CH4 sources exhibit high temporal variability, often differing by more than 10-fold among repeated observations. This variability introduces challenges for estimating source emission rates because the same source can appear to be large on one drive-by and small on the next. Additionally, the frequency distribution of CH4 enhancements from a given source generally has a strong positive skew that can lead to overestimation of leak size. The magnitude of CH4 enhancements from a source measured with a mobile sensor can also change quickly over time, as indicated by decreasing temporal correlation between mobile measurements longer than an approximately hourly time scale. To manage the uncertainty, we demonstrate how additional survey effort can help overcome this variability and instability to allow discrimination among the wide range of leak sizes. We quantify the probability of source detection, finding that it increases with estimated leak size. Combining these results, we develop a simulation that demonstrates the potential for ALD to detect leaks and quantify emissions as a function of sampling (driving) effort. Our results suggest that five to eight drives of each roadway in a target area would detect >90% of leaks and provide adequate emissions quantification for repair/replacement prioritization.
Major phonemic problems of Bangladeshi learners of English: Reasons behind and solutions
Authors: Islam A K M Mazharul
Published: June 2021

The issue of Bangladeshi EFL learners’ phonemic challenges, though not very battered, has been addressed by some researchers at different times. Even after having a prolonged history of learning and teaching and some research in the field, awkward pronunciations and misunderstandings are still prevailing everywhere, from the primary level to tertiary level and beyond. This study is undertaken to heighten the importance of delving deeper into the root causes of phonemic difficulties of the learners and to pinpoint the major problems. To add flesh to the theoretical skeleton of the topic a group of university students was interviewed along with a questionnaire to check their understanding of English phonology along with some other basic questions related to pronunciation. It can firmly be stated that teaching/learning pronunciation and hence starting from the segmental level has never been followed. Like any other country where English is in the status of a second language or foreign language, it is very natural to face difficulties to master the intricate phonemic features of the target language for the learners. Supposedly, it mostly results from the lack of knowledge of phonology and phonetics of the target language and due to the phonemic differences between the first language and the target language. In this study, the focus is kept mainly on the salient phonemic challenges faced by Bangladeshi learners of English. Bringing in the basic ideas of consonant and vowel sounds, the sound production mechanism is shown, and then the differences between the vowels and consonants of two languages are held out. Tracing out the key difficulties, some suggestions are provided. This writing is expected to be of considerable and comprehensive help for the instructors as well as for the interested learners and crucial addition to the literature of the topic.
Condolence strategy used by Facebook user to respond obituary news

Published: June 2021

Technology has changed the world of human communication today. News, information, and issues are delivered through technological advances with incredible speed. Social media such as Facebook are one of many technology mediators used by the people in the world to share information. This information can be in many forms, such as personal information, selling information, obituary information and etc. Obituary information is shared by the people on Facebook and responded to by other people with various responses. This study is descriptive research to find the strategy used by people in the Indonesian context while responding to the obituary updated on Facebook. The subjects are lecturer’s wife, artist, and an abortion girl. This study has described the responses from Facebook users as the strategy in responding to the obituary. The finding of this study showed that the condolence strategy used always depends on the person who dies itself. The person who is seen as the good person will have a good response, while someone who is seen as a bad person, in this case, the girl who did an abortion, has a positive and negative response.

Published: June 2021

From many discussions on wilderness in literary works, only a few focus on the young adult dystopian, even more on Suzanne Collins’s The Hunger Games. For this reason, this article aims to portray the wilderness in the book as the survival resource since the previous studies fail to point out such an issue. This recent study is conducted by descriptive qualitative methods. As the theoretical basis, the discussion employs Garrard’s account of wilderness and Ross’s myth of wilderness in American literature. As a result, the discussion depicts the wilderness as the natural woodland surrounding District 12 and the artificial battleground of the Games in Panem. The woods in Katniss’s district enable her to provide for her family and develop such literacy in the wilderness. This literacy is advantageous in the Games arena, thus helps Katniss to be one of the winners. The findings might provide such an insight to the reader to live harmoniously with nature, even more with the wilderness.
Remarks on continuously distributed sequences
Authors: Paštéka M.
Published: June 2021

In the first part of the paper we define the notion of the density as certain type of finitely additive probability measure and the distribution function of sequences with respect to the density. Then we derive some simple criterions providing the continuity of the distribution function of given sequence. These criterions we apply to the van der Corput's sequences. The Weyl's type criterions of continuity of the distribution function are proven.
El discurso político neopentecostal en las elecciones presidenciales de 2018 en Costa Rica: Un análisis desde la teoría de la justicia de John Rawls
Authors: A. Aguilar Ramírez Esteban , Porras Navarro Daniel
Published: June 2021

En el presente artículo se analizan los discursos y declaraciones emitidas por miembros del Partido Restauración Nacional, en especial de su candidato a presidente, durante la campaña electoral del año 2018 en Costa Rica, sobre temas relativos a los derechos humanos, como el matrimonio igualitario, el aborto, la llamada familia tradicional, entre otros. A partir de esto decidimos analizar si este tipo de declaraciones y discursos podrían ser catalogados como discursos de odio o llamados a la intolerancia y, por lo tanto, deberían limitarse y no ser tolerados, o si, por el contrario, dicha limitación se podría entender como una violación a la libertad de expresión.

Published: June 2021

Dimensional measurements were recorded to observe the durability of press-formed paperboard trays used for food processing via heating and cooling of the paperboard trays containing oatmeal. A set of the studied press-formed paperboard trays were dried before being heated, and a set of the paperboard trays were heat-sealed before being cooled to compare the effects of drying and sealing on the durability of the tray. In addition, empty trays were heated to observe the impact of food processing conditions on its durability via leak tests with a colouring solution as well as optical analysis of the material coating on the surface of the trays. The drying process of the trays was observed to improve the dimensional stability of the trays while being heated, and heat-sealing the trays yielded a major positive impact on the dimensional stability of the trays while being cooled. The leak tests and optical analysis results on the heated empty trays showed a negative durability impact from the food processing conditions. It was concluded that adjusting the heat-sealing parameters and food processing conditions is necessary in order to achieve improved durability of the press-formed paperboard trays for food processing purposes.

The present study investigated the physical and neutron- and gamma-ray-shielding features of a sodium oxide (Na2O)-doped lead (Pb)–silicate glass system. The chemical composition of the glass system is described by the formula xNa2O–50SiO2·(50 − x)PbO, where x = 0, 10, 20, 30, 40 and 50 mol%. Moreover, the shielding features were investigated by utilizing the Geant4 simulation code and the Xcom program. The density of the glasses (ρglass) was enhanced from 2.460 to 6.995 g/cm3. The mass attenuation coefficient (MAC, μ/ρ) was calculated. The MACs were arranged in the order of (NSP50)MAC> (NSP40)MAC> (NSP30)MAC> (NSP20)MAC> (NSP10)MAC> (NSP0)MAC. The half-value layer varied from 14.23 to 2.55 cm for NSP0 to NSP50, respectively, at 0.015 MeV. The mean free path (MFP) values ensured the shielding capacity for NSP-glasses, as it was found to possess the shortest MFP, and its value at 0.015 MeV changed from 20.53 to 3.68 cm for NSP0 and NSP50, respectively. The NSP50 glass sample has the highest Zeff, which increased from 32.70 to 76.93. The calculated exposure buildup factor values were greater than those of the energy absorption buildup factor at fixed energy and penetration depth for all studied glasses. The fast neutron removal cross-section ∑R(cm−1) increased gradually with the increase in lead (II) oxide content. Finally, one can conclude that the investigated NSP0–NSP50 glasses are superior materials for neutron and γ-ray shielding.

Published: June 2021

La presente disertación, se orienta hacia el análisis sobre el proceso de paz en Colombia según el ordenamiento colombiano y desde un contexto histórico desde el cual se consideran los aspectos y factores que han hecho perdurar el conflicto. Los conflictos en Colombia se remontan desde los años de la independencia de Suramérica, en las cuales se luchó por la libertad frente al yugo español, sin embargo, las olas de violencia no cesaron porque hasta siglos después perduran con enfrentamientos intestinos, ya no por temas de territorialidad extracontinental sino por desacuerdos en ideológicos entre los partidos liberales y conservadores. Así se originaron grupos de enfrentamientos en la zona rural de Colombia, en la búsqueda del poder, del dominio, en un inicio en nombre de la justicia y la inclusión, entre otros, pero luego por la consecución de objetivos mediados por posiciones políticas extremas. Así como el conflicto también ha habido intentos de arreglos para la consecución de la paz, en tal sentido el acuerdo del proceso iniciado en 2012 hasta su firma en 2016 y posterior aplicación hasta el 2020. Estas dinámicas fueron examinadas desde una perspectiva cualitativa, de revisión sistémica documental, bibliográfica y de análisis, por lo que se infirió, entre algunas conclusiones; que se deben definir acuerdos con responsabilidad penal de los que han delinquido en contra de las personas, bienes públicos, generando diversos actos de violencia, privación de libertad y asesinatos masivos.
