Crítica e clínica na autogenealogia de Nietzsche (1886-8)
Authors: Pacheco Lemos Frederico 
Published: August 2023

A proposta deste trabalho é analisar o movimento de releitura que Nietzsche faz de sua própria obra entre os anos 1886 e 1888, comentando os cinco prefácios a obras anteriormente publicadas (escritos em 1886) e o livro Ecce Homo (de 1888). Por essa via, perguntamos se caberia denominar este movimento de uma autogenealogia e problematizamos as possíveis correlações entre uma dimensão crítica e uma dimensão clínica da filosofia de Nietzsche, por um lado, e entre a vida e a obra do autor, por outro; reavaliando por fim o alcance da tarefa nietzschiana por excelência: transvalorar todos os valores.
De l’écriture N’Zassa à la métatextualité dans D’éclairs et de foudres de Jean-Marie Adiaffi
Authors: Guehi Germain 
Published: August 2023

La parole poétique, tout en servant de vitrine à la manifestation de l’art oratoire dans le milieu traditionnel, transcende, à partir des attributs culturels, l’écriture jusqu’au mélange des genres littéraires dits écriture N’zassa, source de pratique métatextuelle. Un style d’écriture qui fait intervenir dans l’énoncé écrit, les proverbes, le mythe, le conte, le chant, la danse, les sonorités tambourinées, sédiments esthétiques normalement réservés à la production artistique en milieu traditionnel. Cette littérature exige du lecteur, une connaissance des valeurs du terroir de l’écrivain. Comment la poésie N’zassa participe-t-elle de la métatextualité ? Il s’agit de dévoiler, dans le cadre de cette étude, la poésie orale comme étant une essence de l’oralité ; d’analyser les procédés métatextuels dans l’écriture hybride avant d’identifier les enjeux sous-jacents. Grâce aux outils méthodologiques de la sociocritique et de la psychocritique, il ressort que la parole poétique procède de l’oralité ; la métatextualité est présente dans l’énoncé N’zassa à divers degrés ; la pratique fictionnelle développe un double enjeu de construction d’une écriture conforme aux valeurs traditionnelles négro-africaines et de quête de dignité culturelle.

Published: August 2023

Governments and cities are increasingly launching smart city (SC) schemes to address the challenges posed by rapid urbanization and population growth in municipalities. Smart cities utilize data from various sources within a metropolis to enhance urban development, promote qualitative lifestyles, and focus on economic and environmental sustainability. Big data analytics (BDA) plays a crucial role in collecting and analyzing vast amounts of data from SC infrastructures, enabling effective management and implementation of smart city initiatives. BDA helps explore data collected through Internet of Things (IoT) devices and sensors, identifying trends, and making appropriate changes, ultimately making smart cities more efficient, sustainable, and beneficial for their inhabitants. However, big data in SC also presents potential risks and challenges related to urban security and the well-being of residents.
The literature review examines various research approaches, techniques, algorithms, and architectures proposed to address the challenges of handling big data in smart cities. Urbanization's growing trend is causing challenges in managing basic amenities and resources in urban areas, necessitating innovative solutions to ensure efficient functioning and improved quality of life for citizens. Previous research has highlighted the significance of big data analytics in driving smart city decision-making, yet many smart city big data initiatives have faced difficulties in implementation. To overcome these challenges, researchers have explored techniques like artificial intelligence, machine learning, data mining, and deep learning, as well as architectures encompassing layers of instrumentation, middleware, and application for end-users. Additionally, researchers have emphasized the importance of selecting appropriate sensors for efficient data collection and explored low-cost smart traffic systems to improve urban traffic management. Overall, this review synthesizes insights from nine scholarly papers, shedding light on approaches to handling big data challenges in smart cities.

Published: August 2023

ImportanceBoth augmented reality (AR) and virtual reality (VR) have had increasing applications in medicine, including medical training, psychology, physical medicine, rehabilitation, and surgical specialties, such as neurosurgery and orthopedic surgery. There are little data on AR’s effect on patients’ anxiety and experiences.ObjectiveTo determine whether the use of an AR walkthrough effects patient perioperative anxiety.Design, Setting, and ParticipantsThis randomized clinical trial was conducted at an outpatient surgery center in 2021 to 2022. All patients undergoing elective orthopedic surgery with the senior author were randomized to the treatment or control group. Analyses were conducted per protocol. Data analysis was performed in November 2022.InterventionAR experience explaining to patients what to expect on their day of surgery and walking them through the surgery space. The control group received the standard educational packet.Main Outcomes and MeasuresThe main outcome was change in State-Trait Anxiety Inventory (STAI) from the screening survey to the preoperative survey.ResultsA total of 140 patients were eligible, and 45 patients either declined or were excluded. Therefore, 95 patients (63 [66.3%] male; mean [SD] age, 38 [16] years) were recruited for the study and included in the final analysis; 46 patients received the AR intervention, and 49 patients received standard instructions. The AR group experienced a decrease in anxiety from the screening to preoperative survey (mean score change, −2.4 [95% CI, −4.6 to −0.3]), while the standard care group experienced an increase (mean score change, 2.6 [95% CI, 0.2 to 4.9]; P = .01). All patients postoperatively experienced a mean decrease in anxiety score compared with both the screening survey (mean change: AR, −5.4 [95% CI, −7.9 to −2.9]; standard care, −6.9 [95% CI, −11.5 to −2.2]; P = .32) and preoperative survey (mean change: AR, −8.0 [95% CI, −10.3 to −5.7]; standard care, −4.2 [95% CI, −8.6 to 0.2]; P = .19). Of 42 patients in the AR group who completed the postoperative follow-up survey, 30 (71.4%) agreed or strongly agreed that they enjoyed the experience, 29 (69.0%) agreed or strongly agreed that they would recommend the experience, and 28 (66.7%) agreed or strongly agreed that they would use the experience again. No differences were observed in postoperative pain levels or narcotic use.Conclusions and RelevanceIn this randomized clinical trial, the use of AR decreased preoperative anxiety compared with traditional perioperative education and handouts, but there was no significant effect on postoperative anxiety, pain levels, or narcotic use. These findings suggest that AR may serve as an effective means of decreasing preoperative patient anxiety.Trial RegistrationClinicalTrials.gov Identifier: NCT04727697

Published: August 2023

AbstractRecently, by forming a P‐rich P–S system, the P3S monolayer has been predicted to have good resistance to air oxidation, large band gap, high absorption, and superior mobility. Inheriting this prediction, a series of ternary Janus P6XY (X/Y = S, Se, and Te; X ≠ Y) monolayers based on P3X nanosheet are designed and studied. The structures of P6XY monolayers are confirmed to be stable based on the evaluation of calculated results for phonon spectra, ab initio molecular dynamic simulations. It is also found that P6XY compounds possess anisotropic mechanical characteristics. All Janus structures are indirect semiconductors with large energy gaps varying from 2.12 to 2.60 eV calculated by the hybrid functional. Besides, biaxial strain significantly affects the electronic properties of the P6XY monolayers. In particular, the biaxial strains can induce a transition from indirect to direct bandgap in all three P6XY structures. The carrier mobility in the three proposed structures exhibits directional anisotropy and high electron mobility value, up to 1.27 × 103 cm2 V−1 s−1, which are suitable for applications in high‐performance and direction‐dependent nanoelectronic devices.

Published: August 2023

AbstractObjectiveThis study aimed to determine if using a pre‐gerotal fat patch at open partial nephrectomy (PN) as a haemostatic bolster is a viable alternative to using synthetic haemostatic agents.Materials and methodsHuman Research Ethics Committee approval was obtained for audit of a prospectively kept database from July 2012 to July 2021, which followed outcomes of patients who received a low‐tension pre‐gerotal fat patch renorrhaphy at open PN. Patient demographics, intraoperative measures, histological outcomes and post‐operative complications were analysed. Using a retroperitoneal approach, the peritoneum was mobilised and a vascularised pedicle of pre‐gerotal fat was rotated in the direction of the kidney. Routine definition of the hilum, clamping of the hilar vessels and dissection of mass followed. After watertight closure and haemostasis, the harvested pre‐gerotal fat patch was placed over the defect and secured using low‐tension renorrhaphy. Two‐layer closure of the abdominal wall with placement of a drain was routine.ResultsA total of 55 patients underwent open PN. Mean age was 60.4 (35–77) years. There were 38 men and 17 women, and 32 right and 23 left PNs. Mean mass size was 31.9 mm (10–95 mm) and collecting system was breached in 36.5% of cases. One patient (1.9%) suffered a Clavien–Dindo IIIb complication requiring return to theatre and transfusion due to a bleed from an intercostal artery. There were no renal bed bleeds, urine leaks or urine fistulas detected. Mean intraoperative blood loss was 355 mL (50–1500 mL) and mean post‐operative creatinine increased by 10.7 μmol/L (51–172 μmol/L). Mean follow up was 40.2 (4–109) months.ConclusionUtilisation of an anatomical pre‐gerotal fat patch to provide pressure at the renorrhaphy site during open PN is an effective technique to assist with surgical haemostasis. This simple technique avoids the costs of haemostatic agents, whilst adding minimal operating time to procedures.

Published: August 2023

AbstractYoung children's noncompliance with adult instructions has the potential to lead to a variety of other internalizing and externalizing difficulties that impact learning, behavior, and overall development. Although a variety of effective intervention strategies exist, early childhood teachers may not be well equipped to consistently implement these strategies to prevent and address young children's noncompliance. Therefore, the purpose of this study was to evaluate the effectiveness and efficiency of a novel teacher implementation support, emailed prompts, to promote early childhood teachers' effective instruction delivery with three children referred for noncompliance and related challenging behaviors. Results indicated that all three teachers increased their accuracy of effective instruction delivery with concomitant improvements in children's response to instructions, including compliance. Furthermore, data suggested that all three teachers spontaneously generalized effective instruction delivery to other non‐referred children in their classrooms. Results, implications, and limitations are discussed.

Published: August 2023

AbstractWe describe the facile synthesis of [(Me3Si)2CH]2E=PMes* (E=Ge, Sn) from the reaction of the tetrylenes with the phospha‐Wittig reagent, Me3P−PMes*. Their reactivity towards a range of substrates with protic and hydridic E−H bonds (E=N, O, Si) is described. In addition to hydroelementation reactions of the E=P bonds, we show that these compounds, particularly [(Me3Si)2CH]2Sn=PMes*, also act as base‐stabilized phosphinidenes, allowing phosphinidene transfer to other nucleophiles.

AbstractAlternative to current liquid amine technologies for post‐combustion CO2 capture, new technologies such as adsorbent‐based processes are developed, wherein material lifetime and degradation is important. Herein a robust method to determine degradation rates in a laboratory setup is developed, which was validated with a continuous multi‐staged fluidized bed pilot plant designed to capture 1 ton CO2 per day. An amine functionalized polystyrene adsorbent showed very good agreement between the experimental 1000‐hour laboratory degradation rates and 2200 hours of degradation in a pilot plant. This validates how laboratory experiments can be extrapolated for sorbent screening and for scale‐up. Resulting, the oxidative degradation in the desorber at high temperatures (120 °C) and low O2 concentrations (150 ppmv) is 3 times higher compared to the adsorber at low temperatures and high O2 (56 °C, 7 vol %). Laboratory degradation experiments can hence be used to further optimize process operations to limit degradation or screen for potential new adsorbents.

IntroductionThe performance of robot‐assisted laparoscopic pyeloplasty has recently been increasing in frequency. However, patients with duplicated renal pelvises and ureters can present challenges.Case presentationA 71‐year‐old woman presented with flank pain and was diagnosed with ureteropelvic junction obstruction with an incomplete duplicated collecting system. Preoperative imaging did not reveal the details of the stenosis. Therefore, three reconstructive procedures were prepared: The Anderson–Hynes procedure, end‐to‐side pyeloureterostomy, and upper pole ureter to lower pole pyeloplasty with the Anderson–Hynes procedure for the lower pole. These procedures were determined by the length of the intact ureter and the presence of crossed vessels. During the surgery, the crossing vein was severed, allowing successful reconstruction with Anderson–Hynes anastomosis.ConclusionPreoperative evaluation and preparation of multiple surgical techniques are crucial in robot‐assisted laparoscopic pyeloplasty for incomplete duplicated collecting systems.
Two‐sided markets: The influence of market power on information utilization strategy and welfare
Authors: Cui Zhanhong , Li Kai 
Published: August 2023

AbstractIn the digital age, platforms have leveraged consumer data to discern product preferences, thereby bolstering transaction rates via personalized recommendations. As such, consumer information not only serves as a crucial resource for market expansion but also as a competitive tool for personalized recommendations. Our research explores the strategic application of consumer information by dual‐sided platforms, within the context of two upstream merchants vending identical goods. We scrutinize the decision‐making process of these platforms in three distinct scenarios, examining their propensity to utilize consumer information for personalized recommendations, and the subsequent ramifications on pricing, consumer surplus, and social welfare. Our findings suggest a tendency among platforms to exploit consumer information, thereby inducing merchants to adopt a standardized pricing strategy through adjusted commissions. However, when a significant disparity in platform strengths is present, the more dominant platform is inclined to elevate commission levels, leading to discriminatory pricing by merchants. Interestingly, our study reveals that on platforms where information utilization and pricing strategies are optimally balanced, consumer surplus escalates in tandem with the intensification of inter‐platform competition. In contrast, total social welfare diminishes with increased competition. This research offers valuable insights into the strategic use of consumer information by platforms, with significant implications for pricing strategies, consumer surplus, and social welfare.

Published: August 2023

AbstractHerein, ethylene‐vinyl acetate copolymer/styrene ethylene butylene styrene (EVA/SEBS) blend foam with wide effective damping temperature range (ΔT) was prepared via supercritical nitrogen. The influence of the ratio of EVA and SEBS on the foaming and damping properties was studied. ΔT gradually widened into the high temperature region with the increase of SEBS content, and higher SEBS gave denser and more uniform cell structure and reduced the density of the blend foam. When the content of SEBS was 40 phr, the density of the blended foam was 0.185 g/cm3, and the ΔT was −3~54°C. These damping foams were lightweight and this work showed that damping performance could be controlled by simply adjusting blend content, which is of great significance to broaden the application environment of damping materials.Highlights
EVA/SEBS foam was prepared by supercritical nitrogen.
EVA and SEBS blends can broaden the damping temperature range.
The damping temperature range was −3.0~54.6°C when SEBS content was 40 phr.
An Efficient Synthesis of Benzimidazole‐pyrazines via the Sequential Ugi/Hydroamination/Cyclization Reactions

Published: August 2023

AbstractThis study reported an efficient two‐step method based on the sequential post‐Ugi hydroamination reaction for synthesizing a novel class of benzimidazole‐pyrazines with high yields. First, a Ugi fourcomponent reaction (Ugi‐4CR) is carried out using readily available starting materials, i. e., 1H‐benzo[d]imidazole‐2‐carboxylic acid, aldehydes, propargylamine, and isocyanides, in methanol at ambient temperature. Afterward, the Ugi products undergoes a sequential intramolecular hydroamination/cyclization reaction between a nitrogen of imidazole and alkyne functional group in aqua media in the presence of AuCl3 as a catalyst to obtain benzimidazole‐pyrazine products. These heterocyclic compounds may have a potential to be utilized in designing modern drugs with desirable features.
The Media in Southern Europe: Continuities, Changes and Challenges
Authors: Papathanassopoulos Stylianos , Giannouli Iliana , Archontaki Ioanna 
Published: August 2023

AbstractThe media systems of Portugal, Spain, France, Italy, Malta, Greece, Cyprus and Turkey represent what Daniel Hallin and Paolo Mancini have proposed as the Southern European or polarised pluralistic model. Regardless of their differences, the media in Southern Europe are characterised by low levels of newspaper circulation, a tradition of advocacy reporting, instrumentalisation of privately owned media, politicisation of public broadcasting and broadcast regulation and limited development of journalism as an autonomous profession. In the digital era, the media in Southern Europe have to adjust themselves to the new conditions, as citizens have turned rapidly to the digital and social media, regardless the uneven development of the Internet in most countries. It seems that digitisation of the media landscape has led the Southern European media to follow a path not very dissimilar to other European countries as in the past. The advent of digital and social media, as well as the emergence of citizen journalism, has made the news media landscape even more uncertain for the legacy media and the professional journalist, but less controlled by the state, which used to be the norm in the analogue past.
