Published: September 2022

Context

Vaccination status has been shown to be linked to patient-centered outcomes in those with COVID-19. However, minimal data have explored the relationship between vaccination status and representation rates after receiving monoclonal antibodies (MABs) the Delta strain of severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) in a community setting.

Objectives

The authors sought to determine if there was a difference in patient-centered outcomes between those who were vaccinated and unvaccinated after the administration of casirivimab/imdevimab for mild-to-moderate COVID-19 during the time when the Delta strain was most prevalent.

Methods

A convenience sample of consecutive adults given casirivimab/imdevimab at either an outpatient infusion center or within the emergency department (ED) were included in analysis. Patient demographics, authorized-use qualifiers from the emergency use authorization (EUA), baseline vital signs at the time of infusion, representation rates to a healthcare provider within the hospital’s network, and any admissions to the hospital following infusion were all collected from the patient’s electronic medical record. Vaccination status was confirmed in both the patient’s electronic medical record and the Arizona State Immunization Information System (ASIIS). Analysis was conducted utilizing descriptive statistics, the Mann–Whitney U test for continuous data, and the chi-squared analysis for nominal data.

Results

In total, 743 patients were included in the study, with 585 being unvaccinated and 158 being vaccinated at the time of administration. Those in the vaccinated group were more likely to be older (60.0 vs. 55.0 years; p<0.001) and to have a history of diabetes (18.4% vs. 11.3%; p=0.02), hypertension (39.9% vs. 28.5%; p=0.006), immunosuppression (7.0% vs. 1.4%; p<0.001), and chronic kidney disease (7.0% vs. 3.4%; p=0.05). In the entire sample, 105 (14.1%) patients had an unexpected return visit to either the ED or urgent care at 28 days, with 17 (2.3%) requiring hospitalization. Patients who were vaccinated were more likely to represent for care after casirivimab/imdevimab infusion (20.3% vs. 12.5%; p=0.01), but no difference was noted in hospitalization rates between the two groups (18.8% vs. 15.1%; p=0.15).

Conclusions

MAB therapy with casirivimab/imdevimab for the outpatient treatment of mild-to-moderate COVID-19 was associated with a low rate of hospitalization. However, those who were vaccinated were more likely to present for unexpected return care at either the ED or urgent care within 28 days of the initial infusion.
Multifunctional on-chip directional coupler for spectral and polarimetric routing of Bloch surface wave

Published: September 2022

Integration of multiple diversified functionalities into an ultracompact platform is crucial for the development of on-chip photonic devices. Recently, a promising all-dielectric two-dimensional platform based on Bloch surface waves (BSWs) sustained by dielectric multilayer has been proposed to enable various functionalities and provide novel approach to photonic devices. Here, we design and fabricate a multifunctional directional coupler to achieve both spectral and polarimetric routing by employing asymmetric nanoslits in a dielectric multilayer platform. Due to the dispersion property of BSWs, the directional coupling behavior is sensitive to wavelength and polarization. We demonstrate numerically and experimentally the wavelength selective directional coupling of TE BSW mode with an intensity ratio of the BSW excitation in opposite directions reaching 10 dB. Polarization selective directional coupling is also achieved at specific operating wavelength due to different response to a nanoantenna for TE and TM BSWs. The proposed two-dimensional photonic device opens new pathway for a wide range of practical applications such as molecular sensing, imaging with different polarization, and spectral requirements.
Nanophotonic-assisted precision enhancement of weak measurement using spin Hall effect of light
Authors: Kim Minkyung , Lee Dasol , Kim Yeseul , Rho Junsuk
Published: September 2022

The spin Hall effect of light, i.e., the microscopic and spin-dependent transverse splitting of linearly polarized light into circular polarizations at an optical interface, has been considered as a promising candidate for high-precision measurement when combined with a weak measurement technique. However, in those previous demonstrations, the precision is determined by the interface of interest, hindering its versatility. Here, by leveraging the direct correlation of precision with the spin Hall shift, we propose nanophotonic-assisted approaches to increase the precision of the weak measurement by controlling the spin Hall effect of light at the target interface. The refractive index sensing of an isotropic medium is demonstrated as a proof of concept, in which the precision can be increased, in principle, to infinity by placing an index-below-unity slab in the vicinity of the target interface. Furthermore, a single-layer metasurface comprising two-dimensional subwavelength patterns is introduced as an experimentally favorable platform. This study lays the foundation for nondestructive and high-precision investigation of unknown parameters of interfaces and will find wide sensing applications in material science, medical engineering, and other interdisciplinary fields.

Authors: Esteves Cláudia V. G. , Sevastyanova Olena , Östlund Sören , Brännvall Elisabet
Published: September 2022

High alkali impregnation (HAI) increases the total yield of softwood pulps following kraft cooking. This yield improvement is also maintained after oxygen delignification. This study evaluates how bleaching with either chlorine dioxide or hydrogen peroxide affects the final yield of samples obtained with standard and HAI. The chemical composition, viscosity, brightness, mechanical and morphological properties were studied. Compared to cooking after standard impregnation the yield improvement achieved by HAI was preserved in both types of bleaching sequences (2 % units for chlorine dioxide and 4 % units for hydrogen peroxide). The introduction of charged groups into the cellulose fibers was higher with hydrogen peroxide bleaching than with chlorine dioxide however, no significant impact was seen on the swelling or mechanical properties. The brightness was higher for the pulps bleached with chlorine dioxide compared with hydrogen peroxide. Hydrogen peroxide bleaching resulted in similar brightness development for both standard and HAI. Fibers bleached with chlorine dioxide had the highest curl index (16–17 %) compared to the fibers bleached with hydrogen peroxide (15 %).

Published: September 2022

Class F fly ash from both fresh and stored sources, along with finely milled sand and limestone were tested by conventional strength index approaches based on ASTM C618-2019, Standard Specification for Coal Fly Ash and Raw or Calcined Natural Pozzolan for Use in Concrete and EN 450-1:2012 - Fly ash for concrete. Definition, specifications and conformity criteria for pozzolan activity. Mortars were made with both European and U.S. standard sands. Pozzolanic activity was also measured directly by Ca(OH)2 uptake via thermogravimetric analysis and electrical resistivity. The EN 450 method proved a more reliable measure of pozzolanic activity than the ASTM equivalent, which provided false positives, probably due to the narrow gradation of the U.S. standard sand and the rheologic benefit of the fly ash on the mortar. A four-point Wenner probe was used to measure the electrical resistivity on the 40 × 40 × 160 mm mortar prisms. The resistivity correlated with the measure of strength index and pozzolanic activity by other methods. The pozzolanic reaction of the Class F fly ash was found to be relativity slow, with a latency period of at least 21 days and only small indications of activity at 28 days. Unlike compressive strength, the resistivity of the control mortars did not change significantly after 28 days and remained essentially flat over one year. The resistivity of the fly ash test prisms showed continuous increase over the same period, achieving 150 % to >500 % of control at 90 days. This may be contrasted with the compressive strength data of 90 % to 110 % for the EN-450 data. The measurement of resistivity is rapid, simple, precise, and non-destructive and made with inexpensive equipment that is relatable to pozzolanic activity. It is found to be more sensitive and selective than that provided by conventional strength index methods.

Objective: to unveil experts’ experiences on traces not preserved by health and safety professionals. Methods: qualitative research developed with 27 criminal experts through telephone interview. Data were processed in IraMuTeQ and analyzed by the Descending Hierarchical Classification. Results: four thematic classes were obtained that evidenced the existence of a communication gap with the pre-hospital service experienced by experts, who believe that training of these professionals and police officers is necessary. In cases of differentiation between suicide and homicide, experts experience corpse mobilization, in addition to weapon removal from the original location. Health professionals mischaracterize the victim’s corpse and leave health care objects, such as gloves and syringes, in place, while police mischaracterize the scene, move objects and do not adequately isolate the scene. Conclusion: experts experience forensic traces not preserved by health and safety professionals in the position of objects and the victim’s corpse, feel a communication gap and point out the need for training and awareness of professionals. Contribution to practice: the findings can redirect the training of police officers and health professionals who work with crime situations.

Authors: Chong Xue Ling , Drittenbass Lisca , Dubois-Ferriere Victor , Assal Mathieu
Published: September 2022

Current literature has described many of the complications following hallux valgus surgery and their treatment options.

Iatrogenic transfer metatarsalgia is a distinctive and challenging complication that has not been addressed in a comprehensive fashion yet.

Iatrogenic transfer metatarsalgia may result from poor preoperative assessment, planning and/or surgical technique.

We have classified the causes of iatrogenic transfer metatarsalgia based on a multiplanar assessment of the malalignment(s) and are recommending a comprehensive treatment algorithm to guide surgeons in addressing this complication.

With this knowledge, surgeons may avoid potential pitfalls in the primary surgery that can result in iatrogenic transfer metatarsalgia and find the appropriate treatment option to correct them.

Published: September 2022

The activity and some properties of glucose oxidase (EC 1.1.3.4) of the wood-degrading fungus Lentinus (Panus) tigrinus VKM F-3616D were studied. The results showed that 12 days of dynamic liquid-phase cultivation increased the activity and the biosynthetic levels of the enzyme with maximal activity at day 6. After 6 days, a decrease in the glucose oxidase activity was observed. The enzyme isolated via ion exchange chromatography had an optimal pH of 4.0 and a temperature optimum of 50 °C. Spectrophotometry, fluorescence analysis, and IR Fourier spectroscopy showed that the enzyme was a flavoprotein and that its prosthetic group contains flavin adenine dinucleotide. The relative kinetic parameters of the enzyme were determined: the Michaelis constant (Km) was 4.1 x 10-3 M, and the maximal rate of the enzymatic reaction (Vmax) was 0.36 IU. Results of electrophoresis in native and denaturing conditions were consistent with an enzyme structure having two equal subunits with a total molecular mass of approximately 160 kDa.

Published: September 2022

Increasing global paper consumption has fostered the search for new alternative non-wood fiber sources. The aquatic weeds Cyperus digitatus, Cyperus iria, and Scirpus grossus were analysed for their fiber characteristics and chemical composition, and the processed fibers were transformed into handmade paper. The selected species yielded medium-length fibers (0.92 mm to 1.03 mm), which were thin-walled with a lumen diameter (3.37 µm to 5.26 µm) wider than cell wall thickness (2.73 µm to 2.97 µm). In terms of fiber derived values, the selected species possessed a slenderness ratio of 86.5 to 113.1 (favourable, > 30) and flexibility coefficient of 35.2 to 47.6 (favourable, within the range 50 to 70), which was classified as rigid fiber. The species also contained high cellulose, 42.1% to 44.8% (favourable, > 40%) and hemicellulose content, 42.8% to 45.6% (favourable, within the range of 30% to 50%), and low lignin content, 10.6% to 11.8% (favourable, < 12%). Handmade paper of Cyperus digitatus possessed relatively high tensile strength (2.61 ± 0.15 kN/m) and breaking length (1.20 ± 0.07 km) among studied species. Comparison with other non-wood fibers indicated that the studied plants fibers can be used for production of paper plates, paperboard, and decorative paper.

Published: September 2022

Background and aims

Gambling disorder is characterized by problematic gambling behavior that causes significant problems and distress. This study aimed to develop and validate a predictive model for screening online problem gamblers based on players' account data.

Methods

Two random samples of French online gamblers in skill-based (poker, horse race betting and sports betting, n = 8,172) and pure chance games (scratch games and lotteries, n = 5,404) answered an online survey and gambling tracking data were retrospectively collected for the participants. The survey included age and gender, gambling habits, and the Problem Gambling Severity Index (PGSI). We used machine learning algorithms to predict the PGSI categories with gambling tracking data. We internally validated the prediction models in a leave-out sample.

Results

When predicting gambling problems binary based on each PGSI threshold (1 for low-risk gambling, 5 for moderate-risk gambling and 8 for problem gambling), the predictive performances were good for the model for skill-based games (AUROCs from 0.72 to 0.82), but moderate for the model for pure chance games (AUROCs from 0.63 to 0.76, with wide confidence intervals) due to the lower frequency of problem gambling in this sample. When predicting the four PGSI categories altogether, performances were good for identifying extreme categories (non-problem and problem gamblers) but poorer for intermediate categories (low-risk and moderate-risk gamblers), whatever the type of game.

Conclusions

We developed an algorithm for screening online problem gamblers, excluding online casino gamblers, that could enable the setting of prevention measures for the most vulnerable gamblers.
Gender, Science, and Two Cultures in Marion Zimmer Bradley’s "The Ruins of Isis" (1978)
Authors: Övermann Cora Zoé
Published: September 2022

Willkommen auf dem Planeten Isis, früher bekannt als Cinderella. Dies ist der Ort, an dem Marion Zimmer Bradley ihr Gedankenexperiment des spekulativen Science-Fiction-Romans The Ruins of Isis (1978) angesiedelt hat. Das Experiment basiert hauptsächlich auf folgender Tatsache: Isis ist ein Matriarchat und wird somit von Frauen regiert. Beginnend mit der Umbenennung des Planeten von Cinderella zu Isis formuliert die Autorin eine scharfe Beobachtung traditioneller Geschlechterrollen und Machtstrukturen, wobei sie sich mit ihrer Hauptfigur Cendri, einer Anthropologin, und deren Ehemann Dal, einem Archäologen, besonders auf die Wissenschaften konzentriert. Das Ergebnis ist ein klarer Kommentar zu den Kulturen, welche einander im Roman gegenüberstehen: Bewohner verschiedener Planeten, Frauen und Männer, Geisteswissenschaften und Naturwissenschaften. In diesem Artikel wird betrachtet, wie die Figuren, Kulturen und Disziplinen durch das, was C. P. Snow als »gegenseitiges Unverständnis« bezeichnet hat, getrennt sind. Es wird argumentiert, dass es Ziel des Romans ist, eben jene Trennung zu überwinden, und gleichzeitig bestehende Verhältnisse in den Wissenschaften und deren Interaktion mit gesellschaftlichen Strukturen kritisch zu hinterfragen.p { margin-bottom: 0.25cm; line-height: 120% }

Bantuk, britek, búrok és Afrika déli része a búr háború egyik magyar résztvevőjének szemszögéből
Authors: Szabó-Zsoldos Gábor
Published: September 2022

Szakmai berkekben is kevéssé ismert tény, hogy a Brit Birodalom egyik legjelentősebb 19. századi erőpróbája, a búr háború vagy más néven a dél-afrikai háború (1899–1902) számos magyar vonatkozással rendelkezik. A hadi események értékelése kapcsán kialakult közéleti vita búr- és britbarát résztvevői egyaránt előszeretettel szemlélték a búr köztársaságok (Transvaal és Oranje Szabad Állam), valamint a brit erők küzdelmét az 1848–1849-es forradalom és szabadságharc emlékezetének aspektusából. A brit hadsereg Magyarországon vásárolt, mint utólag kiderült, vélhetőleg silány minőségű lovakat. A botrány a brit és magyar törvényhozásban is komoly viták tárgyát képezte. A 20. századi magyar irodalom nagy alakjai (pl. Ady és Kosztolányi) pedig reflektáltak a búr háborúra. A dél-afrikai frontok és Magyarország közti legközvetlenebb és talán legérdekesebb kapcsolódási pontot viszont a háborút megjárt magyarok jelentik. Közéjük tartozik Péchy Tibor, aki 1896-ban vándorolt ki Transvaalba, majd a háborúban, 1900. január–szeptember közt harcolt a búrok oldalán. A tanulmány bemutatja Péchy nézőpontját, különös figyelmet szentelve annak a kérdésnek, hogy a magyar önkéntes dél-afrikai kézirataiban miként látja az idegen kultúrákat, amelyek képviselőivel a búr háború kitörése előtt és alatt találkozott először.

Necessary Optimality Conditions in the One Discrete Boundary Problem of Population Dynamics Control
Authors:   Baku State University, Agamaliyeva Aigun
Published: September 2022

One discrete problem of optimal population dynamics control with a controllable initial condition is considered. The process is described by a nonlinear system of Fredholm-type difference equations. An analogue of the L.S. Pontryagin’ maximum principle is proved by imposing a series of smoothness conditions on the right side the equation. The linearized maximum principle and the analogue of the Euler equation are proved for the case of convexity and openness of the control domain, which are first-order necessary conditions for optimality.
On the Control Problem of a Two-link Flat Manipulator with Nonseparate Multipoint Intermediate Conditions
Authors:   Institute of Mechanics of NAS of RA, Barseghyan Vanya , Simonyan Tamara ,   Yerevan State University, Matevosyan Aram ,   Yerevan State University
Published: September 2022

The article solves the problem of programmed control of the movement of a two-link flat manipulator on a fixed base with given initial, final conditions and unseparated values of the phase vector at intermediate points in time. Absolutely rigid links of the manipulator are interconnected by an ideal cylindrical hinge, and using the same hinge the first link is fixed to the base. Thus, the manipulator can perform movements only in the horizontal plane. The movements of the manipulator are described by a system of second-order Lagrange equations. The task of constructing programmed movement control of such a dynamic system is to construct laws of change in control moments that allow the manipulator to carry out programmed movement that transfers the system from a given initial state, ensuring satisfaction of the unseparated multipoint intermediate conditions, to the final state. Solutions of the considered problem are constructed using the methods of theory of control of finite-dimensnal systems with unseparated multipoint intermediate conditions. As an application of the proposed approach, functions of control and corresponding movement are constructed with given unseparated conditions on the coordinates of the phase vector at some two intermediate points in time. The corresponding graphs are constructed for the coordinates of the phase vector of the manipulator, confirming the theoretical results obtained.

Published: September 2022

Although agriculture is crucial to economic growth in South Africa, the industry faces several challenges, including the effects of pests and diseases that contribute to crop loss. Such losses severely affect the maintenance of food security. Therefore, a major challenge is finding effective, environmental-friendly control measures for insect pests. Potatoes are among the four most widely consumed vegetable crops worldwide. However, a potato crop can be infested by various pests, like the devastating leaf miner, Liriomyza huidobrensis (Blanchard) (Diptera: Agromyzidae). The leaf miner species has, since the early 2000s, become an important pest of various vegetable crops in South Africa. The species is highly invasive, causing up to 70 % damage of solanaceous crops. The damage that is caused by the leaf miner is direct, resulting from the female flies feeding on the leaf mesophyll during oviposition, and the larvae mining the leaves. Indirect damage is induced through pathogens entering through perforations that act as vectors of plant diseases. Biocontrol agents, e.g.  entomopathogenic nematodes (EPNs), entomopathogenic fungi (EPF), and parasitoids have shown potential against L. huidobrensis. This review investigates the biology and morphological identification of L. huidobrensis, its host range in the Western Cape, and the potential of associated biocontrol agents, like EPNs, EPF and parasitoids, as future control options.
INCITING VIOLENCE AND PROPAGATING HATE THROUGH THE MEDIA: RWANDA AND THE LIMITS OF INTERNATIONAL CRIMINAL LAW
Authors: Frans Viljoen
Published: September 2022

The media played a significant role during the 1994 genocide in Rwanda. Media messages took two forms: incitement to kill (or “incitement to violence”), and hate propaganda (or “hate speech”). In 2003, the International Criminal Tribunal for Rwanda (ICTR) convicted three media leaders of, amongst others, genocide and incitement to commit genocide. This contribution is an attempt to find out whether these convictions are based on the speech and responsibility for speech through the media − distinct from other actions including utterances outside the context of the media − of the accused. If any of these convictions are in fact based on mediamessages, does “incitement to violence” or “hate speech” constitute the basis for such convictions? Conceding the difficulties of disentangling these different forms of speech, the conclusion is that the convictions are based on “incitement to violence”, and not on “hate speech” as such.

Sexual abuse is not something the victim thereof discloses easily; on the contrary it is likely to give rise to feelings of shame and self-loathing. Facing the perpetrator and accusing him or her in a court of law is even more difficult. It is not surprising that perpetrators of these deeds will hardly ever be faced with criminal or delictual consequences of their vile conduct. When the victims eventually muster the courage to speak, it is often too late, because the sell-by date of the remedy has passed. The crime or delict, depending on what recourse the victim is seeking, has prescribed. The Supreme Court of Appeal recently allowed a claim which to all intents andpurposes had prescribed. In the Netherlands the prescription period in the case of sexual abuse likewise makes allowances for the victims of sexual abuse. This note proposes to compare recent case law of the Supreme Court of Appeal and the Hoge Raad (Dutch Supreme Court of Appeal) against the background of the different prescription provisions which apply in the two countries.
WINNING A CIVIL CASE WITHOUT GIVING ANY KIND OF EVIDENCE WHATSOEVER? Jordaan v Bloemfontein Transitional Local Authority [2004] 1 All SA 496 (SCA), 2004 3 SA 371 (SCA)
Authors: David M Matlala
Published: September 2022

The standard of proof in a civil case is the well-known preponderance (balance) of probabilities. This requires of the party on whom the onus lies, in order to be successful, to satisfy the court that he is entitled to succeed on his claim or defence, as the case may be (Pillay v Krishna 1946 AD 946 952-953). The onus of establishing a case in accordance with this standard is on the party who makes the assertion since if a person claims something from another in a court of law, he has to satisfy the court that he is entitled to it (Pillay v Krishna supra 951; and Van Wyk v Lewis 1924 AD 438 444). According to Voet (22.3.10) the position is: “He who asserts, proves, and nothe who denies, since a denial of a fact cannot naturally be proved, provided that it is a fact that is denied and that the denial is absolute.” The person who makes the claim, and accordingly bears the onus of proof, is invariably the plaintiff. However, there are situations in which the defendant bears the onus. This ordinarily happens when the defendant is not content with a mere denial of the claim against him but sets up a special defence. In respect of the special defence the defendant becomes the claimant. For the specialdefence to succeed the defendant must satisfy the court that he is entitled to succeed on it (Pillay v Krishna supra 952; Corpus Juris (D.44.1.1); and Voet 22.3.9).The word “onus”, in this context, refers to the duty which is cast on the particular litigant, in order to be successful, of finally satisfying the court that he is entitled to succeed on his claim or defence, as the case may be. This is the meaning of the word in its true and original (primary) sense. In this sense the onus never shifts from the party upon which it originally rested (South Cape Corporation (Pty) Ltd v Engineering Management Services (Pty) Ltd 1977 3 SA 534 (A) 548A-B). In a secondary sense the word means the duty cast upon a litigant to adduce evidence in order to combat a prima facie case made by the opponent. In this sense the onus refers to the burden of adducing evidence in rebuttal. This may shift or be transferred in the course of the case, depending upon the measure of proof furnished by the one party or the other (South Cape Corporation (Pty) Ltd v Engineering Management Services (Pty) Ltd supra 548).
KIDNAPPING BY DECEIT R v Cort [2003] 3 WLR 1300; [2004] 4 All ER 137 (CA)
Authors: Shannon Hoctor
Published: September 2022

The nature of consent, and its ambit and operation as a criminal law defence, remains somewhat unclear (see De Wet De Wet en Swanepoel Strafreg 4ed (1985) 94). This is not surprising, given the fact that the assessment of whether consent is present is largely determined on the basis of public policy. Unlike other justification grounds which indicate that, all things considered, the conduct in question was the right thing to do (eg defence), consent “embodies a recognition that the autonomy of the other person (‘victim’) is involved, and that if that person agrees to the conduct there should be no offence” (Ashworth Principles of Criminal Law 3ed (1999)331). Recognizing a defence of consent involves taking the individual will into account, in allowing individuals “to assume those consequences that they took into account when they adopted the decision; that is, in permitting them to incorporate these consequences into the course of their lives” (Nino The Ethics of Human Rights (1991) 180). It is clear that the law allows a person complete right of disposal over her property, but does not recognize her consent to the taking of her life by another. More difficult questions arise in relation to whether there can be consent to a violation of bodily integrity, particularly in the area of sport andmedical treatment (see Burchell Principles of Criminal Law 3ed (2005) 333-338). A particularly significant question, which is central to the discussion which follows, is when the apparent consent of the complainant can be excluded. Though it is settled law that consent induced by force or threats is not recognized for the purposes of the criminal law (Burchell 341), the position is not as clear with regard to whether consent induced by fraud will be excluded as a defence (Van Oosten and Labuschagne “Bedrieglike Voorstellings en Toestemming in die Strafreg” 1977 De Jure 80 81). This issue will be discussed below, in the light of the case of R v Cort.

Published: September 2022

Las diversas formas del existir humano y de las expresiones materiales e inmateriales de su autocomprensión han sido objeto, en los estudios humanísticos, de un tratamiento plural e interdisciplinario en el que pervive la idea del mejoramiento posible de las facultades humanas y de sus efectos positivos para la convivencia con los otros y en la naturaleza, más allá, claro, de la inevitable acumulación de desencanto crítico y escepticismo ante progresos lineales, grandes relatos e identidades esencialistas. En sintonía con lo anterior, este libro ofrece una serie de miradas contemporáneas al problema de la vida buena, y se concentra en esclarecer, en cada caso, dimensiones específicas de las técnicas y figuraciones con las que la vida se da forma a sí misma.

The sample of this research is 120 respondents who already have NPWP in Jakarta and surrounding areas. The study's results prove that religiosity has a positive effect on tax evasion, and Machiavellian has no effect on tax evasion. In contrast, gender has a significant negative effect on tax evasion. In addition, gender can moderate the relationship between religiosity against tax evasion, but gender cannot moderate the relationship between Machiavellian and tax evasion.
