Contribution to the knowledge of Mediterranean lichen-feeding darkling beetles of the genus Stenohelops Reitter, 1922 (Coleoptera: Tenebrionidae)
Authors: NABOZHENKO MAXIM V. , MPAMNARAS ATHANASIOS , KALAENTZIS KONSTANTINOS
Published: December 2020

Species of the genus Helopelius Reitter, 1922 (type species: Stenomax aeneipennis Allard, 1876) were known from Rhodes and North Africa. We found that two species described from Rhodes belong to the genus Stenohelops Reitter, 1922, and Helopelius can be interpreted as a subgenus within latter, guided by the article 23.2 of ICZN. The following synonyms are proposed: Helopelius, stat. n. (from genus to subgenus) = Stenomaleis Español, 1957, syn. n.; Stenohelops Reitter, 1922 = Gunarellus Reitter, 1922, syn. n.; Stenohelops (Helopelius) aeneipennis (Allard, 1876) = Helopelius disgregus Reitter, 1922, syn. n., = Gunarus gayirbegi Nabozhenko & Keskin, 2009, syn. n. As a result, the following species are transferred from the former genus Helopelius to the genus Stenohelops: Stenohelops (Helopelius) nodifer (Kraatz, 1880), comb. n.; Stenohelops (Helopelius) otini (Antoine, 1949), comb. n.; Stenohelops (Helopelius) subsinuatus (Antoine, 1951), comb. n.; Stenohelops (Helopelius) verrucosus (Vauloger de Beaupré, 1900), comb. n.; Stenohelops (Helopelius) zaianus (Antoine, 1949), comb. n. Thus, the subgenus Helopelius contains 11 species from three isolated geographical exclaves: Western Mediterranean, Eastern Mediterranean and China. Lectotypes of Stenomax aeneipennis Allard, 1876, Helops gratus J. Frivaldszky, 1894 and Cylindrinotus (Helopelius) disgregus Reitter, 1922 are designated. Data on fossil species of the genus and the allied extinct taxa, as well as on bionomics of extant species of the subgenus Helopelius are presented. The check-list for extant and extinct species of Stenohelops is given.

Authors: CHOI EUNHA , KARANOVIC IVANA , LEE WONCHOEL , ANGEL MARTIN V.
Published: December 2020

Two new planktonic ostracods of the genus Proceroecia Kock, 1992, P. hwanghaensis sp. nov. and P. joseondonghaensis sp. nov., collected from neritic waters off the south coast of South Korea are described. Morphologically, they are similar to P. microprocera (Angel, 1971), the type species of the genus, but show several clear morphological differences, most prominent being the shape of the male endopodite on the second antenna and the presence of a sensilla on the coxale of the fifth limb. The two new species have subtle differences, such as the length of the frontal organ, number of spines on the comb-like e-seta on the first antenna in males, number of spinules on the b-seta on the second antenna in females, etc. Sequences derived from partial mitochondrial cytochrome oxidase c subunit 1 (mtCOI) for these novel species have been compared with sequences available for other Proceroecia species on GenBank, including P. microprocera. These comparisons suggest that both new species are distinct taxa. They also indicate that one set of sequences on GeneBank previously attributed to P. microprocera and derived from material collected from Chinese waters, belong to P. hwanghaensis, and that another set of sequences of an unidentified Proceroecia species from the South China Sea can be attributable to P. joseondonghaensis. Hence, these new species occur widely in the neritic waters of East Asia. The present study increases the number of the known Proceroecia species to nine, and the numbers of halocyprid ostracod species recorded from Korean waters to six.

The Effect of Material and Social Deprivation on Well-Being of Elderly in Europe
Authors: Terraneo Marco
Published: December 2020

In this work, attention is paid to 2 explanatory factors of successful aging. The first is material deprivation. There is growing evidence that poverty is associated with the onset of physical and mental disorders and, broadly, with aspects such as life satisfaction and happiness. The second factor is social deprivation. Social exclusion affects health due to lack of emotional and concrete support; moreover, participation in social activities among older people is associated with greater longevity and a lower risk of disability. The study describes the effect of material and social deprivation on depression (measured through the EURO-D scale) and quality of life (through CASP-12 scale), for individuals aged 50 and older in 14 European countries. Data is derived from Wave 5 of the SHARE project. To estimate the effect of material and social deprivation on outcomes and to determine whether it is moderated by the country in which people live, we apply 2 multi-group path models, respectively, for people aged 65 or younger and for those aged 66 years or older. Findings indicate that higher material and social deprivation is associated with greater levels of stress and worse quality of life. The effect of social deprivation would be stronger than that of material deprivation, and this result seems to be valid in all countries considered, although their intensity varies significantly between them.
Assessing antiretroviral therapy success in HIV/AIDS morbidity and mortality trends in Brazil, 1990–2017: an interrupted time series study
Authors: de Sousa Augusto Cesar Lara , Eleuterio Tatiana de Araujo , Coutinho José Victor Afonso , Guimarães Raphael Mendonça
Published: December 2020

To describe the trends of HIV/AIDS metrics related to the burden of disease for Brazil between 1990 and 2017 we conducted a timeseries analysis for HIV/AIDS indicators by extracting data from the Global Burden of Disease study. We calculated traditional prevalence, incidence and mortality rates, the number of years lost by HIV-related deaths (YLL) and disability (YLD), and disability-adjusted life years (DALY). We estimated time series models and assessed the impact of highly active antiretroviral therapy (HAART) on the same indicators. In the set of disability-adjusted life years (DALY), the highest weight of its magnitude was due to YLL. There was a decline, especially after 1996, of DALY, mortality and YLL for HIV/AIDS. However, YLD, incidence, and prevalence increased over the same period. Also, the analysis of interrupted time series showed that the introduction of HAART into health policy had a significant impact on indicators, especially for DALY and YLL. We need to assess the quality of life of people living with HIV, especially among older adults. In addition, we need to focus on primary prevention, emphasizing methods to avoid infection and public policies should reflect this.
Determination of fundamental coupled torsional—radial frequency of single-walled carbon nanotubes
Authors: Singh Sneha
Published: December 2020

Research indicates that single-walled carbon nanotubes have a unique coupled torsional–radial vibration as one of their fundamental modes. Determination of their vibration frequency is required for efficient use of single-walled carbon nanotube in nano-electromechanical systems. However, there is no mathematical expression for these frequencies and their dependence on single-walled carbon nanotube geometry is unknown. This article examines the effect of diameter, length, and chirality on the fundamental coupled torsional–radial vibration frequency of single-walled carbon nanotube using molecular–structural–mechanics–approach, finite element analysis, and regression analyses. Consequently, a first-ever mathematical form of this frequency is derived. The form quickly and accurately predicts these frequencies at 1.5% in-sample, and 7.2% out-sample mean absolute percentage error. single-walled carbon nanotubes’ fundamental coupled torsional–radial vibration frequency is found independent of diameter and inversely proportional to length where the proportionality constant depends on chirality. The coupling of modes and the similarity of the frequency form with cylindrical shell suggest that single-walled carbon nanotube behave like thin shells in these vibrations. A form for effective circumferential shear modulus of single-walled carbon nanotube is also derived. This modulus is found to depend only on the chirality where achiral single-walled carbon nanotubes have higher values than chiral single-walled carbon nanotubes. Proposed mathematical forms can be used for characterization of single-walled carbon nanotubes, determination of single-walled carbon nanotubes’ effective shear modulus, and tuning operational frequency of single-walled carbon nanotube-based nano-electromechanical systems.

The objectives of this study are to evaluate the structure and protein recognition features of branched DNA four-way junctions in an effort to explore the therapeutic potential of these molecules. The classic immobile DNA 4WJ, J1, is used as a matrix to design novel intramolecular junctions including natural and phosphorothioate bonds. Here we have inserted H2-type mini-hairpins into the helical termini of the arms of J1 to generate four novel intramolecular four-way junctions. Hairpins are inserted to reduce end fraying and effectively eliminate potential nuclease binding sites. We compare the structure and protein recognition features of J1 with four intramolecular four-way junctions: i-J1, i-J1(PS1), i-J1(PS2) and i-J1(PS3). Circular dichroism studies suggest that the secondary structure of each intramolecular 4WJ is composed predominantly of B-form helices. Thermal unfolding studies indicate that intramolecular four-way junctions are significantly more stable than J1. The Tmvalues of the hairpin four-way junctions are 25.2° to 32.2°C higher than the control, J1. With respect to protein recognition, gel shift assays reveal that the DNA-binding proteins HMGBb1 and HMGB1 bind the hairpin four-way junctions with affinity levels similar to control, J1. To evaluate nuclease resistance, four-way junctions are incubated with DNase I, exonuclease III (Exo III) and T5 exonuclease (T5 Exo). The enzymes probe nucleic acid cleavage that occurs non-specifically (DNase I) and in a 5ʹ→3ʹ (T5 Exo) and 3ʹ→5ʹ direction (Exo III). The nuclease digestion assays clearly show that the intramolecular four-way junctions possess significantly higher nuclease resistance than the control, J1.
New Start-up Method for a Closed-Cycle Compression System with Gas Bearings and Its Characteristics
Authors: Lian Huaqi , Wu Hong , Li Yulong , Rong Chengjun
Published: December 2020

Gas bearings, which have the advantages of low frictional resistance and power loss, high rotational speed and high temperature operation, and long life, are more suitable than are traditional liquid lubricated bearings because of their high precision, high rotational speed, and special condition support. However, the problem of starting a closed-cycle compression system with gas bearings still needs to be solved for practical application. Thus, a new start-up method for a closed-cycle compression system with aerostatic gas bearings is proposed in this paper. Further, this paper presents a numerical simulation and experimental investigation of the method’s feasibility and characteristics during the start-up process when the gas tank’s initial pressure is fixed. The results show that the gas tank volume is approximately directly proportional to the start-up time allowable, and a gas tank volume sufficiently small, which not only ensures the feasibility of start-up, but also affects other components only slightly, can be obtained. A perfect combination of radial and axial loads also can be achieved to make the start-up time allowable as long as possible. R134a is a better choice for the working medium than is air, as the start-up time allowable is longer, which leads to a smaller gas tank. This research proposes a new start-up method for a closed-cycle compression system with aerostatic gas bearings which has sufficient load capacity to support system during the start-up method.
Port state control at European Union under pandemic outbreak
Authors: Akyurek Efe , Bolat Pelin
Published: December 2020

Introduction

Port State Control (PSC) is a vital element of sustainable maritime transportation. Inspections of PSC regimes have been ensuring the continuity of the global supply chain as they enforce shipping to implement the maritime regulations to be safe, secure, and environmentally friendly.

Objective

Since the beginning of the COVID-19 Pandemic, the number of onboard ship inspections has decreased inherently for protecting PSC officersand seafarers, while PSC regimes have developed a policy to focus on a high-risk ship based on historical inspection records. In this context, planning for a “new normal” in maritime transportation, it is essential to realize the change in ship inspection numbers and the trend of deficiency - detention factors for the maritime sector to provide current standards. This study aims to present the difference in ship inspection trends between 2017-2020 by focusing on COVID-19 pandemic outbreak data.

Methods

Comparative analysis with Paris MOU ship inspection & detention figures and entropy-based Grey Relevance Analysis has been used as a methodology to reveal the change in inspection trends after COVID-19.

Results

After the pandemic outbreak caused by COVID-19, the number of ship inspections under Paris MOU fell dramatically, however, inspection and detention rate remained the same, also entropy-based Grey Relevance Analysis indicates that detention remarks have also changed compared to last year deficiencies. Detention caused by nautical publication and cleanliness in the engine room has an increasing trend on detentions.

Conclusion

Inspection statistics indicate consistent figures even during the pandemic outbreak, which indicates the current sample group for Paris MOU inspection is healthy. At the same time, entropy-based Grey Relevance Analysis presents a broader insight that the inspection trend on detention deficiencies has varied. Familiarization with the changing trends in inspections will cause fewer detentions of the ships.

Published: December 2020

Background

An estimated 50% of children in the US are Medicaid-insured. Some of these patients have poor health literacy and limited access to medications and specialty care. These factors affect treatment utilization for pediatric patients with atopic dermatitis (AD), the most common inflammatory skin disease in children. This study assesses and compares treatment patterns and healthcare resource utilization (HCRU) between large cohorts of Medicaid and commercially insured children with AD.

Methods

Pediatric patients with AD were identified from 2 large US healthcare claims databases (2011–2016). Included patients had continuous health plan eligibility for ≥6 months before and ≥12 months after the first AD diagnosis (index date). Patients with an autoimmune disease diagnosis within 6 months of the index date were excluded. Treatment patterns and all-cause and AD-related HCRU during the observation period were compared between commercially and Medicaid-insured children.

Results

A minority of children were evaluated by a dermatology or allergy/immunology specialist. Several significant differences were observed between commercially and Medicaid-insured children with AD. Disparities detected for Medicaid-insured children included: comparatively fewer received specialist care, emergency department and urgent care center utilization was higher, a greater proportion had asthma and non-atopic morbidities, high- potency topical corticosteroids and calcineurin inhibitors were less often prescribed, and prescriptions for antihistamines were more than three times higher, despite similar rates of comorbid asthma and allergies among antihistamine users. Treatment patterns also varied substantially across physician specialties.

Conclusions

Results suggest barriers in accessing specialty care for all children with AD and significant differences in management between commercially and Medicaid-insured children. These disparities in treatment and access to specialty care may contribute to poor AD control, especially in Medicaid-insured patients.

Published: December 2020

Background

Extensive research describes how nurses experience their work environment. The conditions are described as stressful and dissatisfying with nurses intending to leave their workplace. Knowledge about the personal perception regarding why nurses consider leaving the hospital workplace is limited. The purpose of this study was to understand why hospital nurses remain in their workplace, which facilitates their continuation in the profession.

Objective

The objective was to explore and describe factors explaining why hospital nurses remain in the workplace.

Methods

This was a descriptive qualitative study with a purposive sample of hospital nurses in Sweden. The salutogenic theory was the basis for the interview guide and the semi-structured questions. Individual interviews were conducted in a hospital in western Sweden. Content analysis was performed to organize the coded data according to the sense of coherence.

Results

Data saturation was achieved with 12 interviews. Within the three themes of coherence (comprehensibility, manageability, and meaningfulness), ten subthemes were categorized from the data as follows: job satisfaction and fun at work, acknowledgement and productivity, togetherness and team security, manageable workload, variable work and challenging situations, workplace and personal space balance, collaboration and supportive leadership, valued role and good work, commitment and involvement, and pride in the professional role.

Conclusions

The main findings of this study have shown the critical importance of being in a meaningful, comprehensible and manageable work context that supports nurses in maintaining their professional identity.

Published: December 2020

Background

Preference assessments of patients with rheumatoid arthritis can support clinical therapeutic decisions for including biologic and targeted synthetic medicines to use. This study assesses patient preferences for attributes of second-line therapies and heterogeneity within these preferences to estimate the relative importance of treatment characteristics and to calculate the minimum benefit levels patients require to accept higher levels of side effects.

Methods

Between November 2018 to August 2019, patients with rheumatoid arthritis were recruited to a survey containing demographic and disease-related questions as well as a discrete choice experiment to measure their preferences for second-line therapies using biologics or Janus kinases inhibitors. Treatment characteristics included were route of administration, frequency of use, probability of mild short-term side effects, probability of side effects changing appearance, probability of psychological side effects, probability of severe side effects and effectiveness of treatment.

Results

A total of 358 patients were included in the analysis. A latent class analysis revealed three preference patterns: (1) treatment effectiveness as the single most important attribute, (2) route of administration as the most important attribute, closely followed by frequency of use and psychological side effects and (3) severe side effects as the most important attribute followed by psychological side effects. In addition, disease duration and mild side effects influenced the patients’ choices.

Conclusion

Respondents found either effectiveness, route of administration or severe side effects as the most important attribute. Patients noting effectiveness as most important were more willing than other patients to accept higher risks of side effects.

Published: December 2020

Background

Leprosy is a chronic infectious disease classified into two subgroups for therapeutic purposes: paucibacillary (PB) and multibacillary (MB), closely related to the host immune responses. In this context it is noteworthy looking for immunological biomarkers applicable as complementary diagnostic tools as well as a laboratorial strategy to follow-up leprosy household contacts.

Methods

The cross-sectional study enrolled 49 participants, including 19 patients and 30 healthy controls. Peripheral blood mononuclear cells (PBMC) were isolated and incubated in the presence of Mycobacterium leprae bacilli. The cells were prepared for surface (CD4+ and CD8+) and intracytoplasmic cytokine staining (IFN-γ, IL-4 and IL-10). Multiple comparisons amongst groups were carried out by ANOVA, Kruskal–Wallis, Student T or Mann–Whitney test. Comparative analysis of categorical variables was performed by Chi-square. Functional biomarker signature analysis was conducted using the global median values for each biomarker index as the cut-off edge to identify the proportion of subjects with high biomarker levels.

Results

The cytokine signature analysis demonstrated that leprosy patients presented a polyfunctional profile of T-cells subsets, with increased frequency of IFN-γ+ T-cell subsets along with IL-10+ and IL-4+ from CD4+ T-cells, as compared to health Controls (Venn diagram report). Moreover, statistical analysis was carried out using parametric or non-parametric variance analysis followed by pairwise multiple comparisons, according to the data normality distribution. L(PB) displayed a polyfunctional profile characterized by enhanced percentage of IFN-γ+, IL-10+ and IL-4+ produced by most T-cell subsets, as compared to L(MB) that presented a more restricted cytokine functional profile mediated by IL-10+ and IL-4+ T-cells with minor contribution of IFN-γ produced by CD4+ T-cells. Noteworthy was that HHC(MB) exhibited enhanced frequency of IFN-γ+ T-cells, contrasting with HHC(PB) that presented a cytokine profile limited to IL-10 and IL-4.

Conclusions

Our data demonstrated that L(PB) displayed enhanced percentage of IFN-γ+, IL-10+ and IL-4+ as compared to L(MB) that presented functional profile mediated by IL-10+ and IL-4+ T-cells and HHC(MB) exhibited enhanced frequency of IFN-γ+ T-cells, contrasting with HHC(PB). Together, our findings provide additional immunological features associated with leprosy and household contacts. These data provide evidence that biomarkers of immune response can be useful complementary diagnostic/prognostic tools as well as insights that household contacts should be monitored to access putative subclinical infection.
On efficient frequency-domain full-waveform inversion with extended search space
Authors: Aghamiry Hossein S. , Gholami Ali , Operto Stéphane
Published: December 2020

Efficient frequency-domain full-waveform inversion (FD-FWI) of wide-aperture data is designed by limiting inversion to a few frequencies and by solving the Helmholtz equation with a direct solver to process multiple sources efficiently. Some variants of FD-FWI, which process the wave equation as a weak constraint, have been proposed to increase the computational efficiency or extend the search space. Among them, the contrast-source reconstruction inversion (CSRI) reparameterizes FD-FWI in terms of contrast sources (CS) and contrasts and updates them in an alternating mode. This reparameterization allows for one lower-upper (LU) decomposition of the Helmholtz operator to be performed per frequency inversion hence further improving the computational efficiency of FD-FWI. However, iteratively refined wavefield reconstruction inversion (IR-WRI) relies on the alternating-direction method of multipliers to extend the search space by matching the data from the early iterations via an aggressive relaxation of the wave equation while satisfying it at the convergence point thanks to the defect correction performed by the Lagrange multipliers. In contrast to CSRI, IR-WRI requires redoing one LU decomposition when the subsurface model is updated. In both methods, the CSs or the wavefields are computed by solving in a least-squares sense an overdetermined linear system gathering an observation equation and a wave equation. A drawback of CSRI is that CSs are estimated approximately with one iteration of a conjugate gradient method, whereas the wavefields are reconstructed exactly by IR-WRI with a Gauss-Newton method. We have combined the benefits of CSRI and IR-WRI to decrease the number of LU decomposition during IR-WRI with a fixed-point (FP) algorithm while preserving its search space extension capability. Application on the 2D complex Marmousi and the BP salt models shows that our FP-based IR-WRI manages to reconstruct these models as accurately as the classic IR-WRI while reducing the number of LU factorizations considerably. A theoretical complexity analysis and a recent application of 3D FD-FWI based upon direct solver suggest that the FP algorithm should reduce the cost of IR-WRI by a factor of approximately 2 and 10 for 3D dense ocean bottom cable and sparse ocean bottom node acquisitions, respectively.

Published: December 2020

Agriculture has advanced tremendously over the last 100 years. In fact it is been keeping up with food production at a very high rate. In fact, some scientists feel that agriculture already produces enough food to feed the world, but of course there are issues and problems with food availability, agricultural production practices, preservation and transportation, and probably more that one can think of that hinder many people in this world from getting adequate food. The basic challenge is to provide food for the needy people. This need can be fulfilled with the help of the farmers taking responsibility in increasing the food production by 50% by the year 2050. The objective of the present work is to increase this food production, protecting the environmentwith managing natural resources. Mainly focusing on water, nutrients and other inputs to produce foods without degrading the environment. The Goal is to develop the social, environmental, and the economic aspects of possible solutions to minimize the agricultural footprint, and become more sustainable. The dataset considered in our experiment is used in yield prediction based on historic yield and weather information. Implemented both the versions of Thomson model and compared the result with segmentation model, Random Forest (RF). Root Mean Square Error (RMSE) and Mean Absolute Error (MAE) are used as evaluation metrics in estimating the performance of models implements and stated that Random forest algorithm is providing 0.07 (RMSE). The outcome of the present research work helps farmers in adopting best management practices and trying to give them the economical and technical support in making easier for them to adopt best management practices.
A Dynamic Prediction for Elastic Resource Allocation in Hybrid Cloud Environment
Authors: Chudasama Vipul , Bhavsar Madhuri
Published: December 2020

Cloud applications heavily use resources and generate more traffic specifically during specific events. In order to achieve quality in service provisioning, the elasticity of resources is a major requirement. With the use of a hybrid cloud model, organizations combine the private and public cloud services to deploy applications for the elasticity of resources. For elasticity, a traditional adaptive policy implements threshold-based auto-scaling approaches that are adaptive and simple to follow. However, during a high dynamic and unpredictable workload, such a static threshold policy may not be effective. An efficient auto-scaling technique that predicts the system load is highly necessary. Balancing a dynamism of load through the best auto-scale policy is still a challenging issue. In this paper, we suggest an algorithm using Deep learning and queuing theory concepts that proactively indicate an appropriate number of future computing resources for short term resource demand. Experiment results show that the proposed model predicts SLA violation with higher accuracy 5% than the baseline model. The suggested model enhances the elasticity of resources with performance metrics.

Published: December 2020

In this work, using the in-silico experiment modeling method, the receptor and its ligands were docked in order to obtain the data necessary to study the possibility of using machine learning and hard intermolecular docking methods to predict potential ligands for various receptors. The protein TRPM8 was chosen, which is a member of the TRP superfamily of proteins and its classic agonist menthol as a ligand. It is known that menthol is able to bind to tyrosine 745 of the B chain. To carry out all the manipulations, we used the Autodock software and a special set of graphic tools designed to work with in silico models of chemicals. As a result of all the manipulations, the menthol conformations were obtained that can bind to the active center of the TRPM8 receptor.

Pada saat ini,Â peserta didikÂ diharapkan untuk memiliki keterampilan sosial dan personal abad 21, yaitu kreatifitas, kolaborasi, berpikir kritis, dan komunikatif karena keterampilan kognitif saja tidak cukup untuk menghadapi tantangan yang akan mereka temukan di masa depan. Hal ini kemudian menjadi tantangan bagi para guru untuk bisa mengintegrasikan keempat komponen tersebut dalam pembelajaran dalam kelas. Pertimbangan ini menjadi latar belakang pelatihan pembuatan Rencana Pelaksanaan Pembelajaran (RPP) yang diperuntukkan untuk guru-guru MGMP di Kalimantan Selatan. Pelatihan ini berupa workshop satu hari dimana para guru belajar mengenai konsep 4 Câ€™SÂ dan di akhir sesi pelatihan mereka diminta untuk berkolaborasi membuat RPP. Pada kegiatan kolaborasi ini guru-guru berdiskusi tentang suatu topik, menentukan langkah-langkah pembelajaran, sekaligus memikirkan dibagian mana mereka menyisipkan 4 C. RPP ditulis pada sebuah kertas karton besar yang kemudian akan didisplay dan dipresentasikan. Pada akhir kegiatan, peserta diminta untuk merefleksi apa yang telah mereka pelajari dan mengisi angket yang berisi persepsi dan evaluasi terhadap program pengabdian masyarakat ini. Peserta kegiatan merasa senang dan mendapatkan manfaat berupa praktik langsung pembuatan RPP serta berkolaborasi dengan rekan MGMP dari berbagai wilayah di Kalimantan Selatan.

Sekolah Dasar Inklusi satu-satunya di Kecamatan Pringapus yaitu SD N Klepu 02 memiliki kendala dalam pelaksanaan pendidikan inklusi karena tidak ada guru pendamping khusus. Di setiap kelas ada dua sampai empat Anak Berkebutuhan Khusus (ABK) yang perlu dilayani secara khusus karena kebanyakan belum cakap dalam hal membaca dan menulis. Melalui kegiatan pengabdian kepada masyarakat ini diharapkan para guru dapat meningkatkan kemampuan dan keterampilannya dalam mengelola pembelajaran bagi ABK khususnya dalam melayani pembelajaran dengan sistem Belajar dari Rumah (BDR) di masa pandemic covid-19. Metode pelaksanaan kegiatan pengabdian ini melalui pelatihan dan pendampingan bagi para guru SDN Klepu 02. Hasil kegiatan menunjukkan peningkatan pengetahuan guru tentang berbagai model pendidikan inklusi dari rata-rata skor 50 menjadi 76. Sedangkan model pengembangan kurikulum yang diimplementasikan di SDN Klepu 02 adalam model modifikasi dan model substitusi. Pembelajaran bagi siswa BDR yang diselenggarakan dalam masa pandemic covid-19 di SDN Klepu 02 dengan aspek menonjol yang tampak adalah melibatkan peran orangtua dan lingkungan belajar siswa (84%), fokus pada literasi dan numerasi, perilaku hidup sehat, spiritual keagamaan, penguatan karakter dan budaya (78%), serta menyederhanakan materi pokok dalam sub-sub materi agar terarah (78%).

‘The Ties That Bind’: Indonesian Female Academic Leaders’ Agency and Constraints in Higher Education
Authors: Arquisola Maria Jacinta
Published: December 2020

Indonesia has achieved equal parity in access to education, income, and career opportunities. Yet in many parts of the country, female academic leaders are still highly under-represented in top academic boards. This study examines how fourteen (14) Indonesian female higher education academic leaders (FALs) enact identity salience and agency in performing their duties, while experiencing social control schemas or ‘triple binds’—exigencies of gender roles, unequal power-plays due to social status and positions, and lack of organizational resources and capital in higher education—in Indonesia, one of the world’s emerging economies still consolidating democracy and building necessary social, fiscal, and physical infrastructures. Taken as a whole, the study found the ‘triple binds’ as aggregate constraints for female leadership progression, driving female academic leaders to resist and rise above this discursive struggle and confrontation through sense-making, assertiveness, depth of conviction, a take-charge attitude, and the use of other tactical strategies like networking with key gatekeepers to obtain the resources they need. The study presents a framework of the triple binds that university leaders can use to assess constraints to academic leadership.
Upgrading Downsizing: Ethics and Personnel Reductions in Declining Organizations
Authors: Walker Keith D. , Kutsyuruba Benjamin
Published: December 2020

Decline and downsizing often create organizational conditions that are tension-filled, problematic, disruptive, and prone to unethical behaviour. It is common for educational organizations to face discontinuity of services and reduction of personnel; therefore, it is important to understand the relationship between declining organizations and the ethical behaviour of educational leaders under these circumstances. In this article, we provide a general description of organizational decline, typical responses to such decline, and highlight the phenomenon of personnel downsizing, with particular attention to the Canadian education context. We offer descriptions of various in situ strategies from several Canadian educational superintendents to illustrate implications for how we might better understand personnel reductions in relation to ethics. We conclude with suggestions concerning ways we might upgrade downsizing with wise judgment and ethical decision-making.
Linearizations for Interpolatory Bases - a Comparison: New Families of Linearizations
Authors: Bueno Cachadina Maria Isabel , Perez Javier , Akshar Anthony , Mileeva Daria , Kassem Remy
Published: December 2020

One strategy to solve a nonlinear eigenvalue problem $T(\lambda)x=0$ is to solve a polynomial eigenvalue problem (PEP) $P(\lambda)x=0$ that approximates the original problem through interpolation. Then, this PEP is usually solved by linearization. Because of the polynomial approximation techniques, in this context, $P(\lambda)$ is expressed in a non-monomial basis. The bases used with most frequency are the Chebyshev basis, the Newton basis and the Lagrange basis. Although, there exist already a number of linearizations available in the literature for matrix polynomials expressed in these bases, new families of linearizations are introduced because they present the following advantages: 1) they are easy to construct from the matrix coefficients of $P(\lambda)$ when this polynomial is expressed in any of those three bases; 2) their block-structure is given explicitly; 3) it is possible to provide equivalent formulations for all three bases which allows a natural framework for comparison. Also, recovery formulas of eigenvectors (when $P(\lambda)$ is regular) and recovery formulas of minimal bases and minimal indices (when $P(\lambda)$ is singular) are provided. The ultimate goal is to use these families to compare the numerical behavior of the linearizations associated to the same basis (to select the best one) and with the linearizations associated to the other two bases, to provide recommendations on what basis to use in each context. This comparison will appear in a subsequent paper.
