Authors: Anas Mohd. , Jamal Mohd Tariq , Ahmad Md. Moneef , Azmi Shujaat Naeem , Alam Md. Firoz
Published: June 2022

The present study investigates the relationship between board characteristics and a firm value. The study offers new insight into the association between board characteristics and a firm value by examining whether board gender diversity alters the impact of board characteristics on a firm value. The study uses panel data approach on a sample of 39 non-financial firms listed in the S&P BSE SENSEX 50 over 6 years (2014–2015 to 2019–2020). An appropriate model between fixed effect and the random effect was selected using the Hausman test first and two separate regressions were run later, showing the direct effect of board characteristics on firm value, and change in the effect of board characteristics on firm value when board gender diversity was put as a moderator. Consistent with the previous findings (Field, Lowry, & Mkrtchyan, 2013; Vo & Bui, 2017; Gulzar, Haque, & Khan, 2020), the study reveals that board busyness has a significant and positive effect on Tobin’s Q only, whereas, board meetings and board gender diversity are the factors that leave a significant negative effect on both return on assets (ROA) and Tobin’s Q. In contrast to existing literature (Chin, Ganesan, Pitchay, Haron, & Hendayani, 2019), we found that the board gender diversity positively moderates the association of board size and board meetings with Tobin’s Q and ROA, respectively.

Published: June 2022

The untreated and sodium chlorite-treated coconut coir was implemented to remove crystal violet (CV) dye from an aqueous solution by batch adsorption experiments. The adsorption capacity, equilibrium time, and adsorption kinetics of CV on both adsorbents were regulated by the pH of the dye solution. High pH favors the comparative adsorption capacity for both adsorbents. In contrast, the untreated coconut coir (UT-CC) shows higher adsorption efficiency (9.61 mg g-1) than sodium chlorite-treated coconut coir (SCT-CC) at low pH. At lower pH (2.00), the equilibrium was established within 60 min by both adsorbents. However, the quick attainment of the equilibrium (30 min) was observed using both the adsorbents at higher pH (8.00). The isotherm data for both the adsorbents was found to have better agreement with the Freundlich than the Langmuir model at pH 8.00. The kinetic data was well-fitted with Ho?s pseudo-second-order model. Both adsorbents were characterized by FTIR and SEM to get evidence for the proposed adsorption mechanism. Density functional theory (DFT) also supports this result which illustrates the adsorption of CV on lignin of CC with the adsorption energy -51.16 kJ/mol at the B3LYP/6-31(d,p) level of theory.

Published: June 2022

Alfalfa (Medicago sativa L.) is the most important forage plant species in Bosnia and Herzegovina. In this study, conducted in Banja Luka, the investigated ten alfalfa genotypes originated from different regions of USA and Europe. The study objective was to determine their grain yield per plants and four morphological properties. The interactions analyses provided to select individual genotypes that are shown the highest stability and yield potential in different production conditions. Genotype with the highest yield shown lower stability level. The influence year and genotype on GYP - the grain yield per plants for investigated alfalfa genotypes was significant (Fexp=7.54* and Fexp= 8.34*). The highest average value for investigated parameter in the first research year had genotypes G53 and G44 and in second research year genotype G2. The lowest value in both research years had genotype G100 (0.28 kg ha-1 and 0.30 kg ha-1. Positive and strong correlations were found between the grain yield per plants and the number of pods per plants (r= 0.74**) and the grain yield per plant and the number of flower per inflorescence (r= 0.51*). On the basis of the obtained values, we conclude that we have excellent genotypes G2, G44, G53 and G51 for successful breeding work in order to obtain new high-yielding varieties of alfalfa.

Published: June 2022

Ostrinia nubilalis Hbn. is a corn pest that can do great damage to plants in
some seasons. The aim of this paper is to study the resistance /
susceptibility of hybrids to the attack of European corn borer and the
effects of different doses of insecticides and time of application in
protection against pests on maize plants, but primarily the influence of
hybrids on attack intensity. The six maize hybrids of different maturation
groups (ZP 427, ZP 434, ZP 555, ZP 600, ZP 606 and ZP 666) used for study
effect of attack of Ostrinia nubillalis Hbn., on control variant T1 without
application of insecticide and on variant treated with two insecticides
Fobos EC (bifentrin - 200 ml ha-1) and combination of Match 050 EC and
Nurelle D (lufenuron 50 g l-1 and hlorpirifos 500 g l-1 + cipermetrin 50 g
l-1), 0.75 l ha-1) in two terms (in the first generation of insect flying T2
and T3 and in the second generation of insect flying T4 and T5) in three
replication. The results showed the highest intensity of Ostrinia nubilalis
Hbn. attack and degree of damages on control variant and significant
differences between treatments for investigated parameters. Observing all
hybrids and treatments, there was no statistical significance between the
six examined maize hybrids of different maturity groups. In the control
variant, the greatest attack (damage) was in plants, namely in the hybrid ZP
666 (94.28%) and ZP 606 (93.90%) and among the variants of applied
insecticides, the greatest damage was found in the treatment T5 with the
applied combination of Match + Nurelle in hybrid ZP 555 and was 92.02%. On
treatment T1-control variant without insecticides, the smallest attack with
Ostrinia nubilalis Hbn. was found in the hybrid ZP 434 (from 88.76%) and
among the variants of applied insecticides, the smallest attack was found on
variant T2 with applied Phobos in the first generation of insect in hybrid
ZP 434 and amounted to 77.12%. The attack of Ostrinia nubilalis Hbn. and
variation of average mass of maize cob varied in dependence of maze of
hybrids and variant of insecticides application.

This instructional case describes an embezzlement committed by the former executive director of a Southeast Idaho nonprofit organization, New Day Products. The case, based on an organization that helps people with disabilities, provides a rich context for students to learn about the important roles and responsibilities of nonprofit organizations' boards of directors. Highlighting the challenges faced by nonprofit boards of directors, the case asks students to consider how New Day Products' board of directors' governance decisions, including choosing financial statement reviews rather than audits, increased the executive director's opportunities to commit fraud.
The Pitch: Managers’ Disclosure Choice during Initial Public Offering Roadshows
Authors: Blankespoor Elizabeth , Hendricks Bradley E. , Miller Gregory S.
Published: June 2022

We examine firm disclosure choice during the initial public offering (IPO) roadshow presentation to understand the informativeness of a management presentation designed to attract investors. Although firms submit a comprehensive registration filing during the IPO, managers also prepare a roadshow presentation, which is shorter and typically allows managers more autonomy to select the information released and how it is discussed. We find that IPO roadshows have significantly more positive, less negative, and less uncertain language than the SEC filing. Using machine learning to classify roadshow sentences into five major topics from the registration statement, we find that roadshows differ in both the topics selected and the language used within each topic. We then examine the predictive ability of the roadshow language, finding that roadshow language predicts future accounting performance, whereas filing language does not. These results highlight the informational role of management presentations, despite the flexibility they grant managers.

When Does the Internal Audit Function Enhance Audit Committee Effectiveness?
Authors: Jaggi Jacob
Published: June 2022

I examine whether audit committees (ACs) improve financial reporting reliability by utilizing an internal audit function (IAF) as a resource and use semistructured interviews with chief audit executives and AC chairs to develop an understanding of the nature of AC-IAF relations. Using AC charters, I measure AC interaction with IAFs, finding improvement in financial reporting reliability for firms that introduce a new IAF under a New York Stock Exchange (NYSE) mandate. This improvement is limited to firms with significant interaction between ACs and new IAFs. Using detailed hand-coded data, I investigate the different kinds of interactions between ACs and IAFs, finding evidence of the importance of private meetings to review the IAF's scope, findings, and recommendations. The value of the IAF as a resource to the AC is greater when the AC ensures free and open communication, promotes IAF independence, and stands in greater ex ante need of monitoring assistance.

Authors: Hellgren Lovisa , Levi Richard , Divanoglou Anestis , Birberg-Thornberg Ulrika , Samuelsson Kersti
Published: June 2022

Objectives: To identify domains of persisting problems at 4 months after discharge in patients previously hospitalized due to COVID-19, with a focus on a subgroup of patients reporting symptoms to an extent indicative of rehabilitation needs.Design: Ambidirectional observational cohort study.Patients: All patients with a laboratory-confirmed COVID-19 diagnosis admitted to hospital in a Swedish healthcare region during the period 1 March to 31 May 2020. After exclusion, 94% of all survivors (n = 433) participated in the study. Forty-three percent (n = 185) of these reported persisting problems indicating rehabilitation needs and formed a subgroup.Methods: Explorative factor analysis based on results from comprehensive telephone interviews covering persisting symptoms, including assessment of impact on daily life.Results: Seven domains were identified, comprising problems related to vision, cognition, mental fatigue, swallowing, voice, sensorimotor dysfunction, and feeling anxious/depressed. The patients in the subgroup reported a median of 8 symptoms/limitationsaffecting everyday life, and two-thirds reported symptoms/limitations in 3 or more domains.Conclusion: Seven problem domains corresponding to specific modalities of rehabilitative interventions were identified. A majority of patients reported problems from several domains, indicating the need for multiprofessional teams in post-COVID-19 rehabilitation. Screening of patients previously hospitalized due to COVID-19 should cover all 7 domains of persisting problems.
LAY ABSTRACTMore than 70% of patients with COVID-19 have previously been shown to experience 1 or several of a multitude of persisting problems several months after infection. This study aimed to identify areas of persisting problems among a broad spectrum of self-reported problems. Survivors of COVID-19 who had been discharged from hospital 4 months previously participated in a telephone interview covering persisting problems, including assessment of impact on daily life. The persisting problems clustered into 7 functional areas. Mental fatigue, cognitive- and sensorimotor problems were reported most frequently. A potential rehabilitation need was seen in more than 40% of patients interviewed. These patients reported approximately 8 different problems affecting their everyday life, and a majority of these patients reported problems from 3 or more areas. These findings highlight the need for multiprofessional teams in post-COVID-19 rehabilitation. Screening of patients previously hospitalized due to COVID-19 should cover all 7 areas of persisting problems.

Published: June 2022

A correlation ratio between a glass transition temperature Tg and average bond energy E (obtained for chalcogenide glasses in L. Tichý & H. Tichá [J. Non-Cryst. Solids, 189, 1995]) was critically analyzed in this paper. As a result, this ratio was shown to have been obtained using incorrect calculations of the average bond energy E through inappropriate application of different averaging procedures for different terms of this parameter and, therefore, it cannot be used in practice. A mathematical algorithm for calculating the average energy bonding was adjusted by the atom-averaging procedure for the both energy of the “network part of a matrix” Ec (energy of heteropolar bonds) and energy of a "residual matrix" Erm (energy of homopolar bonds), as well as considering the impossibility of forming covalent chemical bonds between cations of different type. It was stated that the linear ratio between the glass transition temperature Tg and energy bonding E can be obtained by the ratio Tg ≅ 326∙(E – 0.94) and this claim was proved for 145 typical representatives of the covalent-bonded network chalcogenide glasses (Ge-As-S/Se-type systems).
Loose housing-nothing to lose? Exploring the on-farm profitability, risk and agricultural policy consequences associated with a tie-stall ban on dairy farms
Authors: Hansen Bjørn Gunnar , Jenssen Maria Natalie , Larsson Ingrid Melstveit
Published: June 2022

Due to stricter animal welfare regulations, in Norway tie-stalls for dairy cows are banned from 2034 onwards. The aim of this paper is to explore the profitability, risk and agricultural policy consequences associated with the transition from tie-stalls to loose housing. Data on farm economics and investments were collected from farm enterprise budgets on 66 farms that have built new cowsheds in recent years in Vestland county. Vestland was chosen because on average it has the smallest dairy farms in Norway, with 45 percent of the herds having less than 20 cows. To analyze profitability and risk we used net present value and stochastic simulation. The findings show that irrespective of herd size, to continue farming with an upgraded tie-stall is more profitable than to invest in new loose housing. For farms with less than 30 cows, investment in new loose housing is on average not profitable and involves a high risk. Unless the Governmental investment grant is significantly increased, the tie-stall ban will have large consequences for farm structure and conflict several agricultural policy goals. Farmland in less favored districts may go out of production, making it more difficult to reach the policy goals of increasing food production, agriculture across the country, biodiversity and rural viability. Our findings are of interest to politicians in countries where one considers stricter animal welfare regulations, as well as planners and farmers who consider investing in new loose housing dairies.

Tradition of Besan Bali Marriage in the Muslim Community of Banjarnegara
Authors: Hariyanto Hariyanto
Published: June 2022

This article examines how the Besan Bali marriage tradition in the Muslim community of Banjarnegara and an overview of Islamic law. This type of research is a field research, using qualitative methods with a qualitative descriptive approach. The interview method was used to obtain direct data from the informants. The types of data are primary and secondary data. The results of this study show that the Besan Bali marriage tradition is a tradition of prohibition in marriages that occur between two brothers (besan) that someone who wants to hold a marriage is hindered if the-bride-to-be comes from the Besan family where previously her brother was married to her groom-to-be’s family and vice versa. If it is reviewed based on Islamic law, the prohibition of Besan Bali marriage is actually not in accordance with Islamic teachings, because the reason for the prohibition of Besan Bali marriage is not in accordance with Islamic teachings.
INFLUENCE OF EXTRALINGUISTIC FACTORS ON THE QUALITY OF TRANSLATION OF THE TERMINOLOGY OF ENGLISH TEXTS OF PUBLIC AND POLITICAL TOPICS INTO THE UKRAINIAN LANGUAGE
Authors: Chumachenko Konstantin , Palonova Hanna , Hahirniak Hanna
Published: June 2022

This article has established that the analysis of the linguistic units of the English and Ukrainian languages at the extralinguistic level from the point of view of their semantic structure and cultural significance is of the greatest interest in terms of comparison and translation. Within the framework of the study, the authors identified extralinguistic aspects, translation means and methods of transferring information, which the translator uses when working with a sociopolitical text. In the course of the study, it was established that the peculiarity of socio-political translation is to convey and show the means of transmission of information, which the translator uses in a socio-political text, in which not a simple transmission is highlighted or which is not considered from the point of view of its aesthetic values, and where the axiological aspect of its content is revealed. After all, the success of a text is determined by how effectively language means of influence are used in translation and how an advanced text meets the norms of mass communication adopted in another language community. The authors concluded that any translation focused on conveying only the content of a socio-political text and ignoring the need to ensure its cultural adaptation, in principle, cannot be recognized as adequate. Summing up, we will indicate that when translating socio-political terms, it is necessary to use certain techniques. By means of analysis, the authors revealed that the main translation transformations for high-quality translation of socio-political terms are: tracing, transliteration and transcription, descriptive translation, functional replacement.
Distribution and predators of the invasive spider mite Tetranychus evansi (Acari: Tetranychidae) in the Syrian coastal region, with first record of predation by the native Scolothrips longicornis (Thysanoptera: Thripidae)
Authors: Dayoub Ahmad Malek , Dib Hazem , Boubou Angham
Published: June 2022

The tomato red spider mite, Tetranychus evansi Baker and Pritchard, has emerged as a destructive invasive pest of solanaceous crops worldwide. It was first recorded in Syria in 2011, in Latakia governorate, in the coastal region. Successful management of T. evansi in a given region benefits from information about its distribution, host plants, and associated natural enemies. Therefore, we investigated, in 2019 and 2020, the status of T. evansi on solanaceous plants in the Syrian coastal region, an important producer of solanaceous crops. A total of 237 samples were collected at 187 sites in Latakia and Tartus governorates. Tetranychus evansi was found in 34 cultivated and wild solanaceous plant samples collected at 29 sites distributed across all districts in those governorates, and in a variety of landscapes and elevations, ranging from the coastal plains to high altitudes in the Syrian Coastal Mountain Range. It was collected from three solanaceous crops, namely tomato (Solanum lycopersicum L.), eggplant (Solanum melongena L.) and potato (Solanum tuberosum L.), as well as from two wild solanaceous plants: black nightshade (Solanum nigrum L.) and red nightshade (Solanum villosum Mill.). A total of 14 species of predatory insects and mites, and five species of phytophagous mites, were identified in association with T. evansi. Predatory insects were more frequent and abundant than predatory mites. The insect predator Feltiella acarisuga (Vallot) was the most common and abundant species among the predators, followed by Stethorus gilvifrons (Mulsant) and Scolothrips longicornis Priesner. The predatory mite Phytoseiulus persimilis Athias-Henriot was the most frequent and abundant species of associated predatory mites.
Application of data mining in basketball statistics
Authors: Ma Bin , Wang Yingchun , Li Zheng
Published: June 2022

Data mining is a practice that employs mathematical algorithms to search for hidden information in a large amount of data to analyse the underlying pattern and law, and this practice is also known as knowledge discovery in data. The National Basketball Association (NBA) is the professional basketball game at the highest level in the world, and many events in an NBA game are used for statistical analysis. In this paper, data mining technology was applied based on event statistics to quantify the ability of basketball players and teams, the aim of the exercise being to predict basketball results. According to the NBA (2013–2018) season competition data, the quantitative evaluation method was firstly used to establish a player ability evaluation model, and the feature variable selection history game data weighting method was selected to construct a team player ability evaluation feature system. Secondly, machine learning algorithms such as linear regression, XGBoost and neural network models were used to predict the player performance. Considering the randomness and uncertainty of sports competitions, this paper deploys a combination of data mining algorithms and statistical simulation methods to predict the uncertainty of events, and the results indicate a good prediction effect. Therefore, this combined method is worthy of being applied in the evaluation system of team players and in game prediction.
Some new meaning in the conctpt of "subjectlessness"
Authors: Sarkarova Naila Akhedovna
Published: June 2022

The purpose of study is to explore some new manifestations of the concepts of subjectlessnes and "death of the subject", different from those considered by postmodernism and structuralism, what is its scientific novelty. Among them, quite common is the assessment of some religions as subjectless, especially Islam, supposedly built on the absolute obedience of man to God, where there is no personal active principle. Arguments refuting this point of view are given. Particular attention is drawn to the manifestations of subjectlessnes in the virtual space, where a person loses the features of the integrity of a real subject and acquires new features, breaking up into many avatars that exclude him from cognitive and evaluative discourse. In order to show the features of such virtual non-subjectivity, the author conducts a comparative analysis of the concepts of "knowledge" and "information" and shows that in the latter the "death of the subject" occurs. As a result, it was found that the concept of "subjectlessness" operates not only in literature and art, as postmodernism has shown, but also in other areas of social life and consciousness, including culture, religion, education, and even virtual reality.
Historical truth: directions and techniques of its falsification

Published: June 2022

We treat scalar data compression in sensor network nodes in streaming mode (compressing data points as they arrive, no pre-compression buffering). Several experimental algorithms based on linear predictive coding (LPC) combined with run length encoding (RLE) are considered. In entropy coding stage we evaluated (a) variable-length coding with dynamic prefixes generated with MTF-transform, (b) adaptive width binary coding, and (c) adaptive Golomb-Rice coding. We provide a comparison of known and experimental compression algorithms on 75 sensor data sources. Compression ratios achieved in the tests are about 1.5/4/1000000 (min/med/max), with compression context size about 10 bytes.
Methotrexate monotherapy versus methotrexate and apremilast combination therapy in the treatment of palmoplantar psoriasis: A prospective, randomised, assessor-blinded, comparative study
Authors: Hassanandani Trashita , Panda Maitreyee , Jena Ajaya Kumar , Raj Chinmoy
Published: June 2022

Background:

Palmoplantar psoriasis is a chronic debilitating condition which significantly impairs quality of life.

Objectives:

To assess the efficacy and safety of the combination of apremilast and methotrexate compared with methotrexate monotherapy in the treatment of palmoplantar psoriasis. Also, to study the impact on treatment on the Dermatology Life Quality Index and Palmoplantar Quality of Life Index.

Methods:

A total of 64 patients were randomised to two groups in a 1:1 ratio - Group A received both methotrexate and apremilast in combination, while Group B received only methotrexate, for 16 weeks. The primary endpoints were the mean score of Modified Palmoplantar Psoriasis Area and Severity Index at week 16, the proportion of patients achieving modified palmoplantar psoriasis area severity index-75 and/or Palmoplantar Psoriasis Physician Global Assessment score 0/1 at week 16.

Results:

A significantly higher proportion of patients in Group A achieved Modified Palmoplantar Psoriasis Area and Severity Index-75 at week 16 (43% in Group A vs 30% in Group B). The Modified Palmoplantar Psoriasis Area and Severity Index score was significantly lower in the combination group at week 16 (4.03 ± 2.05 in Group A and 5.89 ± 2.31 in Group B, P-value = 0.002). About 80% of patients in the combination group with baseline Palmoplantar Psoriasis Physician Global Assessment ≥3 achieved Palmoplantar Psoriasis Physician Global Assessment 0/1 compared to 60% in Group B. The combination group showed a significantly higher reduction in Dermatology Life Quality Index and Palmoplantar Quality of Life Index scores compared to the methotrexate alone group (P-value = 0.025). No notable adverse events were observed.

Limitation:

The limitations of the study were single blinding, small sample size and a lack of longer follow up to assess the rate of relapse. We did not account for attrition during sample size calculation. Also, due to the paucity of data regarding the use of apremilast in palmoplantar psoriasis, definitive comparisons could not be made with previous studies.

Conclusion:

The combination of apremilast and methotrexate has superior efficacy and a similar safety profile as compared to methotrexate monotherapy for the treatment of moderate to severe palmoplantar psoriasis.
Outcomes using linear accelerator stereotactic radiosurgery for the treatment of trigeminal neuralgia: A single-center, retrospective study
Authors: Kundu Bornali , Brock Andrea A. , Garry Jason G. , Jensen Randy L. , Burt Lindsay M. , Cannon Donald M. , Shrieve Dennis C. , Rolston John D.
Published: June 2022

Background:

Linear accelerator (LINAC)-based stereotactic radiosurgery (SRS) treatment of trigeminal neuralgia (TN) may have similar efficacy to Gamma Knife SRS (GK-SRS), but the preponderance of data comes from patients treated with GK-SRS. Our objective was to analyze the outcomes for LINAC-based treatment of TN in patients at our institution.

Methods:

We retrospectively analyzed data for patients who underwent LINAC-based SRS for TN from 2006 to 2018. Data were collected from the patients’ medical records. Nonparametric statistics were used for the analysis.

Results:

Of the 41 patients treated with LINAC-based SRS (typically 90 Gy dosed using a 4 mm collimator for one fraction) during that time, follow-up data of >3 weeks post-SRS were available for 32 patients. The median pretreatment Barrow Neurological Institute (BNI) pain score was 5 (range 4–5). The follow-up period ranged from 0.9 to 113.2 months (median 5 months). There was significant improvement in postradiation BNI pain score (P < 0.001), with 23 (72%) patients who improved to a BNI pain score of 1–3. One patient had bothersome hypoesthesia postradiation. Approximately 38% of patients who had initial pain control had recurrence of symptoms (BNI > 3). Survival analysis showed a median time to pain recurrence of 30 months. There was no relationship between prior microvascular decompression (MVD) surgery and change in BNI pain score pre- to posttreatment.

Conclusion:

The results demonstrate that LINAC-based SRS is an effective means to treat TN. Prior MVD surgery did not affect efficacy of SRS in lowering the BNI score from pre- to posttreatment in this patient cohort.

In recent years, multi-phase materials capable of multi-ion transport have emerged as attractive candidates for a variety of electrochemical devices. Here, we provide experimental results for fabricating a composite electrolyte made up of a one-dimensional fast sodium-ion conductor, sodium zirconogallate, and an oxygen-ion conductor, yttria-stabilized zirconia. The composite is synthesized through a vapor phase conversion mechanism, and the kinetics of this process are discussed in detail. The samples are characterized using diffraction, electron microscopy, and electrochemical impedance spectroscopy techniques. Samples with a finer grain structure exhibit higher kinetic rates due to larger three-phase boundaries (TPBs) per unit area. The total conductivity is fitted to an Arrhenius type equation with activation energies ranging from 0.23 eV at temperatures below 550 °C to 1.07 eV above 550 °C. The electrochemical performance of multi-phase multi-species, mixed sodium- and oxygen-ion conductors, is tested under both oxygen chemical potential gradient as well as sodium chemical potential gradient, before and after reaching equilibrium, are discussed using the Goldman-Hodgkin-Kats (GHK) and the Nernst equation. The total conductivity of the degraded cathode and anode terminals is investigated using electrochemical impedance spectroscopy. The degradation investigation of samples indicates a decrease in conductivity adjacent to the anode terminal, the loss of sodium content, and the formation of β-gallia adjacent to the fuel electrode after ~396h at 1463 K.

Organic donor:acceptor semiconductor nanoparticles (NPs) formed through the miniemul- sion method have been shown to be active photocatalysts. Here we report photocatalytic hydrogen (H2) evolution under sacrificial conditions with Pt as a co-catalyst by NPs comprising only the non-fullerene acceptor Y6, stabilized by either sodium dodecyl sulfate (SDS) or the thiophene-containing surfactant 2-(3-thienyl)ethyloxybutylsulfonate sodium salt (TEBS). Typically, changes in the photocatalytic activity of donor:acceptor NPs are associated with differences in morphology due to the use of surfactants. However, as these NPs are single-component, their photocatalytic activity has a significantly lower dependence on morphology than two-component donor:acceptor NPs. Results from ultrafast transient absorption spectroscopy show a minor difference between the photophysics of the TEBS- and SDS-stabilized Y6 NPs, with free charges present with either surfactant. The similar photophysics suggest that both TEBS- and SDS-stabilized Y6 NPs would be expected to have similar rates of H2 evolution. However, the results from photocatalysis show that Y6 NPs stabilized by TEBS have a H2 evolution rate 21 times higher than that of the SDS- stabilized NPs under broadband solar-like illumination (400–900 nm). Transmission electron microscopy images of the Y6 NPs show effective photodeposition of Pt on the surface of the TEBS-stabilized NPs. In contrast, photodeposition of Pt is inhibited when SDS is used. Furthermore, the zeta potential of the NPs is higher in magnitude when SDS is present. Hence, we hypothesize that SDS forms a dense, insulating layer on the NP surface which hinders the photodeposition of Pt and reduces the rate of H2 evolution. This insulating effect is absent for TEBS-stabilized Y6 NPs, allowing a high rate of H2 evolution. The TEBS-stabilized Y6 NPs have a H2 evolution rate higher than most single-component organic photocatalysts, signaling the potential use of the Y-series acceptors for H2 evolution in Z-scheme photocatalysis.
Computational and Experimental Design of Quinones for Electrochemical CO2 Capture and Concentration

Current state-of-the-art thermal technologies for CO2 Capture and Concentration (CCC) from industrial emissions and air are energetically inefficient. In contrast, electrochemical CCC (eCCC) using redox carriers can theoretically approach 100% efficiency. However, there are currently few oxygen-stable redox carriers suitable for eCCC. Quinone derivatives have previously been studied as redox carriers, as they have no affinity for CO2 in the fully oxidized state and an enhanced affinity for CO2 in their reduced states. Unfortunately, the quinones used in prior studies displayed an unfavorable tradeoff between their second reduction potential (E1/2) and CO2 binding constant (KCO2). As a result, reduced quinones that exhibit a sufficient KCO2 for flue gas or atmospheric CO2 capture have E1/2 values negative of the O2/O2•‒ reduction potential. To improve our understanding of the structural and electronic relationships that correlate KCO2 and E1/2, we report the largest set of quinones that have been experimentally evaluated for their KCO2 and E1/2 properties. The trends in the E1/2 and KCO2 properties were further investigated through extensive quantum chemical calculations to inform experimental carrier design. Notably, we identified structural handles to manipulate E1/2 and KCO2 properties of quinones; however, the altered steric and electronic effects did not disrupt their linear dependence.
DIFICULTADES DE LA INCLUSIÓN LABORAL DE PERSONAS CON DISCAPACIDAD DESDE LA PERSPECTIVA DE GÉNERO

Las mujeres con discapacidad son objeto de una multidiscriminación que condiciona significativamente su acceso al empleo y sus condiciones laborales. La brecha salarial de género afecta a este segmento de manera incisiva. Las mujeres con discapacidad reciben un salario inferior al de los hombres del colectivo y al de las mujeres sin discapacidad. Además de desventajas económicas y profesionales, las mujeres con discapacidad también sufren más violencia de género. La última Macroencuesta de Violencia contra la Mujer define 6 tipos de violencia de género y la prevalencia de la violencia en la pareja a lo largo de la vida entre las mujeres con discapacidad acreditada es mayor que entre las mujeres sin discapacidad acreditada en todos los casos. Así, el 20.7 % de las mujeres con discapacidad acreditada ha sufrido violencia física o sexual de alguna pareja frente al 13.8 % de las mujeres sin discapacidad acreditada. El 40.4 % de las mujeres con discapacidad acreditada ha sufrido algún tipo de violencia en la pareja frente al 31.9 % de las mujeres sin discapacidad acreditada. El 17.5 % de las mujeres con discapacidad que ha sufrido VFSEM de alguna pareja dicen que su discapacidad es consecuencia de la violencia de sus parejas. Este porcentaje asciende al 23.4 % entre las mujeres con discapacidad que han sufrido violencia física sexual de alguna pareja.
LA NEGOCIACIÓN COLECTIVA ESPAÑOLA ANTE EL RETO DEL TELETRABAJO
Authors: Gallego Moya Fermín
Published: June 2022

Es misión del Convenio Colectivo adaptar el ordenamiento jurídico a la siempre cambiante realidad sociolaboral, algo que no siempre se acomete de manera acompasada. El reto de actualización que el instrumento convencional como fuente normativa se impone, es complicado, más aún si en el complejo equilibrio negocial irrumpen, sin previo aviso, construcciones jurídicas apenas esbozadas que precisan de una rápida reglamentación. En este último año, es evidente, el teletrabajo ha sido uno de esos cambios, inesperado por su precipitación, que se ha convertido en la estrella del debate iuslaboralista global. Estudios, comentarios, noticias y análisis se han ocupado del mismo desde todos los puntos de vista, tanto en ámbitos especializados cuanto en medios de comunicación generales. En buena lógica, también le han prestado atención los diversos poderes normativos y los agentes sociales, habiéndose asignado a estos últimos un papel muy relevante en la concreción de una normativa tan novedosa como necesaria. En España, el Real Decreto Ley 28/2020 y la posterior Ley 10/2021 de trabajo a distancia han apostado de manera decidida por la intervención convencional sectorial en el desarrollo de un debutante y escueto marco legal, siendo objeto del presente trabajo al análisis de dicha delegación y, en consecuencia, la comprobación del grado de asunción de este nuevo reto por parte de los negociadores colectivos. Del nivel de compromiso de estos últimos dependerá, en gran medida, la implantación exitosa de esta modalidad de prestación laboral.

Wideband Antenna for High-Frequency 5G Wireless Communication
Authors: Kim Ikhwan , Lee Byungje
Published: June 2022

In this study, a wideband patch array antenna for high-frequency 5G wireless communication is proposed. The wideband high-frequency 5G antenna is needed to handle the increase in 5G data traffic. The proposed antenna, a 2 × 16 element array with gap-coupled parasitic elements and a multi-section or stepped transformer feeding network with feed cover to prevent unwanted feed radiation, can cover 5G new radio (NR) n257 (26.5–29.5 GHz), n258 (24.25–27.5 GHz), and n261 (27.5–28.35 GHz) bands. Using parasitic elements with a single substrate instead of cavity and stacked structures, a wide impedance bandwidth (dB magnitude of S11 < –10) of 24.2% (23.75–32 GHz) is achieved. A high cross-polarization discrimination (XPD > 25.2 dB) is achieved using orthogonal dual polarization. The peak gain obtained is 18.69 dB.
