Lag length specification in Engle-Granger cointegration test: a modified Koyck mean lag approach based on partial correlation
Authors: Agunloye Oluokun Kasali , Shangodoyin Dahud Kehinde , Arnab Raghunath
Published: October 2023

The Engle-Granger cointegration test is highly sensitive to the choice of lag length and the poor performance of conventional lag selection criteria such as standard information criteria in selecting appropriate optimal lag length for the implementation of the Engle-Granger cointegration test is well-established in the statistical literature. Testing for cointegration within the framework of the residual-based Engle-Granger cointegration methodology is the same as testing for the stationarity of the residual series via the augmented Dickey-Fuller test which is well known to be sensitive to the choice of lag length. Given an array of candidate optimal lag lengths that may be suggested by different standard information criteria, the applied researchers are faced with the problem of deciding the best optimal lag among the candidate optimal lag lengths suggested by different standard information criteria, which are often either underestimated or overestimated. In an attempt to address this well-known major pitfall of standard information criteria, this paper introduces a new lag selection criterion called a modified Koyck mean lag approach based on partial correlation criterion for the selection of optimal lag length for the residual-based Engle-Granger cointegration test. Based on empirical findings, it was observed that in some instances over-specification of lag length can bias the Engle-Granger cointegration test towards the rejection of a true cointegration relationship and non-rejection of a spurious cointegration relationship. Using real-life data, we present an empirical illustration which demonstrates that our proposed criterion outperformed the standard information criteria in selecting appropriate optimal truncation lag for the implementation of the Engle-Granger cointegration test using both augmented Dickey-Fuller and generalized least squares Dickey-Fuller tests.
Functional regression in short-term prediction of economic time series
Authors: Kosiorowski Daniel
Published: October 2023

We compare four methods of forecasting functional time series including fully functional regression, functional autoregression FAR(1) model, Hyndman & Shang principal component scores forecasting using one-dimensional time series method, and moving functional median. Our comparison methods involve simulation studies as well as analysis of empirical dataset concerning the Internet users behaviours for two Internet services in 2013. Our studies reveal that Hyndman & Shao predicting method outperforms other methods in the case of stationary functional time series without outliers, and the moving functional median induced by Frainman & Muniz depth for functional data outperforms other methods in the case of smooth departures from stationarity of the time series as well as in the case of functional time series containing outliers.

Authors: Füstös Vivien , Erős Tibor , Józsa János
Published: October 2023

A Gemenci-erdő és Béda-Karapancsa területek hullámterei nagy kiterjedésük okán (is) kiemelt természeti értéket képviselnek. A Duna és a mellékágak mederszintjei között az elmúlt időszak süllyedési és feltöltődési folyamatai nyomán egyre nő a különbség, ami beavatkozás nélkül súlyos ökológiai következményeket vetít előre. Egy átfogó morfodinamikai kutatás keretében célul tűztük ki a jelen állapot felmérését, majd erre alapozva javaslatot teszünk egy hosszútávon fenntartható állapotra. A kutatás köztes lépésében ismertetjük a hidrodinamikai modellek első eredményeit, példát hozunk a keresztirányú átjárhatóság (laterális konnektivitás) értékelésére. Bemutatjuk az árvízi kockázatkezelésből ismert vízmélység-vízsebesség alapú besorolási rendszert, amely jelen alkalmazásában jól megfeleltethető a szubjektív besoroláson alapuló potamális osztályozás típusainak. A modell a további, részletes terepi felmérések adatain alapulóan finomításra szorul. Azonban a bemutatott módszertan segíthet a jelen állapot értékelésében és fontos információval szolgál jövőbeni hatásvizsgálatok alapozásához, mind hidrodinamikai, mind ökológiai vonatkozásban.
A Balaton üledék-víz határfelületén zajló hőcsere jellemzése és hatása
Authors: Török Sebestyén Dániel , Torma Péter , Weidinger Tamás
Published: October 2023

A tavi ökoszisztémák egyik legfontosabb fizikai paramétere a vízhőmérséklet, ami közvetlen hatással van a biológiai és a kémiai folyamatok dinamikájára. Az olyan sekély tavak esetében, mint például a Balaton, az üledék hőmérséklete szoros kapcsolatban áll a vízhőmérséklettel, ám ennek ellenére a vonatkozó irodalom túlnyomó részében mégis elhanyagolhatónak tekintik a két térrész közti hőcserét. Ez azonban nem minden esetben tehető meg, mivel bizonyos sekély tavak esetében az energiamérleg több, mint 30%-át is kiteheti az üledékkel való hőcsere. Ezért kutatásunkban a Balaton üledék-víz határfelületén zajló hőcserét vizsgáltuk hosszú idejű mérési adatsorokra alapozva. A mérési program során nemcsak a víz- és üledékhőmérsékleteket monitoroztuk nagy időbeli felbontással, hanem hőárammérő-korongok segítségével közvetlenül mértük az üledék felső rétegében a hőáramot. A vizsgálatok során azt kaptuk, hogy a Balaton üledékének hővezetése olyan esetekben, mikor az üledéket nem zavarja meg a vízmozgás, illetve amikor stabil hőmérsékleti-rétegződés jellemzi a határfelületet, jól jellemezhető egy konstans hővezetési együtthatóval, illetve, hogy a felületi hőcsere számottevően kihat az üledék feletti alsó víztér rétegződésére, amelynek jelentős hatása lehet hidrobiológiai folyamatokra, mint például az oldott oxigénszint alakulására az üledék felszínén. Továbbá rámutattunk, hogy a mederhőáram elhanyagolásával a vízhőmérséklet jól modellezhető, azonban hatását a légkör-víz határfelületen zajló hőcserékkel tudjuk kompenzálni. Ezzel elsősorban a szenzibilis, másodsorban pedig a párolgási hőcsere számításánál követünk el kismértékű hibát.
Két alföldi kisvízgyűjtő éves vízmérlegének meghatározása mért és modellezett adatok alapján
Authors: Quang Hop Tran
Published: October 2023

Vízgazdálkodásunk fontos stratégiai kérdése a területi vízmérlegek jobb megismerése. Ehhez azonban nem rendelkezünk megfelelő részletességű adatokkal, így jobbára hidrológiai modellezéssel próbáljuk ismereteinket kiegészíteni. Mivel azonban ezeket a modelleket nem a magyarországi viszonyokra dolgozták ki, ezért kétirányú kutatást kell elvégeznünk. Egyrészt meg kell határoznunk, hogy a rendelkezésünkre álló (nem egységes területi felbontású, és nem feltétlenül kielégítő gyakorisággal megfigyelt) adatok hogyan használhatók fel az összetett visszacsatolásokkal terhelt környezeti kapcsolatrendszerek modellezésében. Másrészt adódik a kérdés, hogy milyen biztonsággal alkalmazhatjuk hazai körülmények között a nemzetközi gyakorlatban széles körben elterjedt modelleket. Ennek érdekében havi adatok felhasználásával két alföldi kisvízgyűjtőn végeztünk kutatásokat. Ennek során összehasonlítottuk a ténylegesen mért adatokból statisztikai és hidrológiai számítással készült hagyományos (vízkészlet–gazdálkodási mérleg modellel számított) vízmérleget a csapadék-lefolyás (MIKE NAM) és a hidrodinamikai (MIKE Hydro River) modellel számított modellek eredményeivel. A két vizsgált vízgyűjtő (a Dong-ér és a Berettyó) alapadatok tekintetében nagyon különbözött. A Berettyó részvízgyűjtőben számos felszíni víz mérőállomás van. Ezen rendelkezésre álló adatok statisztikai módon kiszámolt tényleges vízhozama lehet egy referencia érték, amelyhez a hidrodinamikai modell kalibrálása elvégezhető. A Dong-ér vízgyűjtő esetében a területi adatok szignifikáns hiánya miatt azokat előbb egy referencia vízgyűjtő segítségével kellett kalibrálni, hogy megbízható modellt alkothassunk. A vizsgálataim rámutattak, hogy a MIKE NAM csapadék-lefolyás és a MIKE Hydro River hidrodinamikai modellek kombinációjával megbízható kalibráció és szimuláció végezhető. A mért adatokból számított statisztikai eredmények alapján kimutatható egyfelől a modellek alkalmassága, sőt megfordítva a modell szimulációs eljárás is alkalmas arra, hogy kiegészíthessük az adathiányos vízgyűjtőkön a felszíni vízkészletek statisztikai értékelését. Bizonyítottuk, hogy a referencia vízgyűjtő kiválasztása – a hidrológiai analógia típusú megközelítés alapján – lényeges mértékben befolyásolja az eredményeket. Eredményeink szerint a hidrológiai analógia alapján paraméterezett modell – tényleges megfigyelések hiányában – a vízhasználatok engedélyezési döntéstámogatásában és alternatív vízkészlet-gazdálkodási javaslatok tesztelésében nagy hatékonysággal alkalmazható.

A Multiscale Comparative Study of the Structure Features of Rapidly Quenched REP-Powders, PM HIP Compacts, Products of Austenitic Stainless Steels and Their Tradi-tional Counterparts
Authors: Shulga A.V.
Published: October 2023

Rapidly quenched REP-powders produced by melt atomization, evidently, are characterized by the same effect of quenching rate on structure features as in traditional solid state quenching. However, the critical cooling rate, determined in the TTT diagram for melt phase transformation: crystallization is much higher than its value for suppressing austenite transformation in carbon steels. Important features of rapidly quenched powders - high dispersity of dendrites and formation of fine grain struc-ture - determine the precipitation of carbides. Direct nuclear methods of activation autoradiography on carbon, track autoradiography on boron, metallography, SEM, EDX, etc were used for investiga-tion. The structure features including the lattice parameter of a solid solution of rapidly quenched REP powders, HIP PM compacts, products of austenitic stainless steels and their traditional coun-terparts were revealed and analyzed taking into account the role of carbon and boron, precipitation of carbides, borides and effect of non-equilibrium states of investigated materials.
Evaluation Of Grain Growth Using Master Sintering Curve And Dilatometry Data For Binder Jetted Parts
Authors: Kancharla Deekshitha , Greifzu Moritz , Marquardt Axel , Eckardt Joanna
Published: October 2023

Metal Binder jetting (BJ) is an additive manufacturing technology that requires a series of post-processing steps to obtain the final product, with sintering being one of the important steps. Multiple coupled phenomena such as densification, coarsening, grain growth, and evolution of microstructure, influence sintering. Grain growth during sintering impacts the final mechanical properties and the densification of a material. The most common method to evaluate the grain growth behaviour is conducting interrupted-sintering analysis followed by microscopy which is a time-consuming process. This work intends to estimate the grain growth during sintering from the shrinkage data obtained from dilatometry. The concept of integrating a master sintering curve (MSC) into the Skorohod-Olevsky-based model is explored to predict grain growth and sintering behaviour. The main aim is to evaluate the adaptability of this approach to BJ.

Organisational performance in the post-COVID era led by top leadership: Focus on the mediating effects of value co-creation mindset
Authors: Oe Hiroko , Yamaoka Yasuyuki
Published: October 2023

In the midst of the transformations brought about by COVID-19 in contemporary society, new approaches and leadership styles are essential to ensure organizational success and sustainability. This paper aims to explore the significance of a mindset focused on co-creating value as a support for post-COVID-19 organizational performance and quantitatively validate its impact. Under the influence of COVID-19, it has become evident that conventional approaches alone are insufficient to guarantee the quality of organizational management. In a context where traditional management models no longer suffice, organizations must possess the capacity for adaptation and transformation. To achieve this, the fostering of a shared value co-creation mindset within the organization is crucial. The paper investigates the mediating effect of a value co-creation mindset on the relationship between top leadership and business performance within the framework of total quality management (TQM). By employing quantitative methods and analyzing 300 datasets collected from an online survey, this study examines the direct and indirect effects of top management leadership on performance, highlighting the mediating role played by the value co-creation mindset. The findings reveal a noteworthy insight into the dynamics of leadership and organizational culture in the post-COVID-19 era. While the direct impact of top management leadership on performance appears to be insignificant, the indirect influence mediated by the adoption of a value co-creation mindset is highly relevant. This suggests that the significance of top management leadership lies in its ability to foster an internal culture that facilitates trust-building between top management and employees and encourages value co-creation. In the context of the co-existence with COVID-19 in the foreseeable future, the implications of these findings are profound. It is evident that organizational sustainability and success hinge not solely on leadership with a clear message but also on the cultivation of shared values as an integral part of the organizational culture. As organizations navigate the challenges and opportunities presented by the post-COVID-19 landscape, the role of leadership and the cultivation of a value co-creation mindset emerge as pivotal factors in charting a course towards enduring success and resilience.

Research progress and applications of image defogging algorithms
Authors: Chen Yi , Yan Shiju , Xu Yunhua , Gu Linping
Published: October 2023

Images taken under hazy weather conditions suffer from problems such as blurring, low contrast, and low saturation due to the scattering of atmospheric light by aerosol particles in the air, which affects the performance and judgment of image analysis equipment. With the rapid development of image processing technology and computer vision technology, researchers have proposed a large number of targeted haze removal algorithms to improve the quality of images taken under hazy weather conditions. According to the haze removal principle, mainstream haze removal algorithms can be classified into three categories: image enhancement-based, physics model-based, and neural network-based. This paper introduces and explores classic haze removal algorithms from the perspectives of principles, development, advantages, and disadvantages, and outlines the prospects for the future development and application direction of haze removal algorithms.
A method for identifying pleural lines in B-mode ultrasound images
Authors: Zhou Tingting , Zhuang Haozhe , Yan Shiju , Xie Erze , Ma Yibo , Zhang Tao , Yu Tianxiang , Deng Shuang
Published: October 2023

In ultrasound imaging, the pleura is visualized as echo reflection formed by the echoes of the interface between the pleura and the lung surface. Three major signs of pleura determines whether the patient has pneumothorax. In this paper, we propose a method to identify pleural line for the diagnosis of pneumothorax. Firstly, the gray threshold of ultrasonic image is properly classified by pre-experiment. Secondly, possible pleural line regions are identified based on threshold classification. Thirdly, the region of pleural line is identified based on the known characteristics of pleural line. The last step is to consider whether it is necessary to modify the threshold to accurately identify the pleural line region. Moreover, we tested 890 ultrasound samples, which included three categories: lung sliding, lung point, and lung sliding disappearance. Each category of samples was divided into two subsets, typical and atypical. The average identification rate reached 90.45%. According to the test results, the advantages and disadvantages of the proposed method as well as the further improvement direction were analyzed. This method for identifying pleural line can serve as the groundwork for developing automatic algorithm for diagnosing pneumothorax.
Precision cooling radiofrequency ablation under tumor boundary temperature control
Authors: Qian Ruiyan , Lin Haixiao , Gu Dandan , Liu Difang , Yao Haitao , Rui Danni , Zhou Yu
Published: October 2023

Radiofrequency ablation (RFA) represents a convenient, minimally invasive, and cost-effective approach for the treatment of small liver cancers measuring less than 3 cm in diameter. Nonetheless, the existing RFA techniques encounter challenges in precisely controlling the extent of ablation and the risk of overheating, which can lead to damage on the surrounding tissues. The ability to control the ablation area also plays a crucial role in the success of RFA procedures. To address these issues, we introduce a novel method that utilizes tumor boundary temperature monitoring to achieve precise control over the RFA process. Through the utilization of COMSOL Multiphysics simulation software, the proposed method was verified by comprehensive simulation and modeling and its efficacy in achieving regional control was testified. Subsequently, ex vivo experiments were conducted employing a custom-designed cooling RFA instrument. The experimental results demonstrated that the RFA controlled by boundary temperature yielded an ablation area with a diameter approaching 30 mm. In comparison to the standard spherical solidification zone (characterized by both the ellipticity and regularity indices of 1), the cooling RFA discoloration zone, under boundary temperature control, exhibited a maximum deviation of 7% in the ellipticity index and 17% in the regularity index. The average ellipticity index was determined to be 0.96, while the average regularity index was 0.86. Collectively, these findings underscore the capability of the proposed temperature-controlled cooling RFA method to attain precise control over the ablation area, contributing to comprehensive ablation of tumor tissue within the target region.
Globalization and Pollution in Central and Eastern European EU Countries
Authors: Simionescu Mihaela
Published: October 2023

Pollution and globalization are current challenges for Central and Eastern Europe (CEE), especially in the context of negative effects of globalization on environment. The aim of this paper is to assess the impact of globalization index on CO2 emissions in the CEE countries that joined the EU in the period 2005-2021. The results based on a panel data approach with DOLS/FMOLS estimators confirm the hypothesis that globalization enhances pollution in this region, but a non-linear relationship was validated between CO2 emissions and globalization index. After reaching a maximum level, the CO2 emissions begin to decrease, while globalization enhances. On the other hand, economic freedom and electricity prices in household consumers had a positive impact on pollution. Renewable energy consumption has the capacity to reduce pollution, while higher electricity prices for non-household users discourage economic activities, which contribute to environmental protection. These empirical findings could support policy proposals to reduce pollution in this region.
Role of Social Support in Mitigating Child Rearing Strain, Among Parents of Differently Abled Children: A Chain Mediation of Family Sense of Coherence and Family External Resources
Authors: Sarwar Adnan Ahmed , Safdar Muhammad Rizwan
Published: October 2023

The family is considered a fundamental cornerstone of society, holding a significant influence over the development of individuals, their emotional well-being, and the overall cohesion of communities. Raising a differently abled child is a fundamental aspect of familial dynamics that encompasses a multifaceted range of obligations, choices, and affective commitments. In view of this, the current research was carried out with the aim of analyzing the influence of child rearing strain on family adaptation, along with the mediation effect of family sense of coherence and family external resources. The current study was conducted using a quantitative research design with survey and cross-sectional research methods. Data were collected from parents of differently abled children between January 2023 and May 2023. The study's scope covered nine divisions of the Punjab province. Data collection was conducted using an interview schedule and carried out with the collaboration of the Punjab Welfare and Baitul Mall departments. The analysis was conducted after gathering data from 200 parents of differently-abled children. Multistage and convenient sampling techniques were applied for data collection. To analyze the mediation results, structural equation modelling was employed to determine the effect of predictor variables on the dependent variables of the study, considering the mediation effect. Based on the major findings of the study, it is concluded that child rearing strain is closely connected with family adaptation and family external resource variables. This suggests that child rearing strain could be mitigated if families had access to external resources and social support to cope with adverse situations.
Unveiling the Impact of Gaslighting on Female Academic Leadership: A Qualitative Phenomenological Study
Authors: Aurangzeb Wajeeha , Abbasi Nabeela Shakur , Kashan Sehrish
Published: October 2023

Gaslighting is a psychological manipulation phenomenon that makes people doubt their own perception and sanity. In light of the prevalence of women in academia, this may have profound effects on academic leadership. Gaslighting is a common problem for women in academic leadership that can be harmful to their mental well-being and ability to develop in their careers. This phenomenon may lead to physical health effects, psychological and emotional stress, work-life balance issues, professional setbacks, low self-esteem, loss of confidence, and low self-efficacy. This study adopted a qualitative phenomenological research design with purposive sampling. Data was collected through semi-structured interviews with 15 mid-career female academic leaders working in two public sector universities in Punjab. Research ethical guidelines were followed by obtaining the informed consent of the participants and keeping their identities confidential. Transcribed data was analyzed through thematic analysis while adopting the IPA (interpretative phenomenological analysis) model. The study provided insights into the causes of gaslighting at the individual and organizational levels. Furthermore, the psychological, emotional, and professional impacts of gaslighting were explored. Participants suggested remedial measures such as awareness, engagement, social networking, documenting and reporting incidents, professional counselling, and boundary-setting skills that may help female academic leaders face and handle this situation effectively.

Published: October 2023

Background: Clean Intermittent Catheterization (CIC) is the preferred bladder management modality among individuals afflicted with neurogenic bladder and has been deemed a safe and effective treatment. Nevertheless, extensive research reveals that adherence to CIC procedures over a prolonged period of time is less than ideal. Aims: This systematic review aims to collect qualitative information from CIC users to comprehend their actual experiences, assess the impact of CIC on their everyday life, and explore practical barriers to CIC use. Methods: Systematic searches were conducted across four databases, CINAHL, PsycINFO, PubMed, and Scopus. The author team evaluated the included articles using the Critical Appraisal Skills Programme checklist for qualitative studies. A meta-synthesis approach was employed in the analysis of the data. Findings: Eleven studies published in English met the inclusion criteria. The meta-synthesis findings based on third-order analysis confirmed twelve sub-themes that integrate into three higher-order themes, ‘psychological experience’, ‘impact on daily life’, and ‘practical barriers’.

Authors: ZHANG Ying , WANG Xiaodong
Published: October 2023

"Appreciate the beauty of each other and share the beauty of all" is the purpose and spirit. The update design of historical blocks, as a part of public environment landscape, attaches importance to its own historical value and aesthetic education value to the contemporary public aesthetics. Historical blocks are the symbols of city history and culture, and also the main content of sustainable development of urban landscape in the new era. They reflect the development trajectory of a city in different historical periods and condense the historical memory of several generations of a city. The renovation of historical blocks should not only focus on spatial form, but also pay attention to socio-economic and cultural factors. Urban micro-update can be regarded as a way to improve and enhance the quality of human life. The focus is mainly on small-scale transformation of existing sites and buildings to meet new functional and aesthetic needs, characterized by small investment, good benefits, and high quality. The East Gate Market in Jinjiang District, Chengdu, is a "small and exquisite" block landscape known for its old Chengdu market cultural experience, backed by the famous writer Li Jieren's former residence. It has typical local characteristics and cultural accumulation. This article takes Chengdu East Gate Market as the research object, adopts both qualitative and quantitative research methods, uses the micro-updating of urban historical blocks as the entry point, conducts field research, summarizes the micro-updating practice experience of Chengdu East Gate Market from the aspects of spatial structure, material space, and cultural landscape, with a view to injecting new vitality into the updating practice of the same type of urban historical blocks and meeting the higher demands of contemporary people for spiritual and cultural life.
Petroleum de Bessora : de la fossile-fiction à l’herméneutique des profonds
Authors: Hachette Pauline
Published: October 2023

Petroleum de Bessora (2004) repose en apparence sur une intrigue policière dont l’objectif est de découvrir l’auteur de l’explosion qui s’est produite sur l’Ocean Liberator, un navire de prospection pétrolière explorant les fonds marins au large de l’île Mandji (Gabon). Bien vite cependant, il apparaît que cet « ultra-deep » qui aimante les convoitises humaines est le véritable épicentre du roman. Foyer de la géographie fossile néocoloniale que son exploitation sécrète en surface, il est aussi le lieu où logent des divinités sous-marines, elles-mêmes reliées aux esprits des forêts. La dynamique verticale qui s’instaure dans le roman, en nous conduisant à faire l’expérience sensible de profonds animés d’énergies aussi matérielles que spirituelles, modifie nos perceptions et nos affects de lecteurs. L’élucidation de l’énigme se double par là d’une herméneutique du territoire déployant les strates et les conflits d’interprétation qui se logent dans les imaginaires de ses habitants.
Les puisatiers du Sahara : regards scientifiques, littéraires et cinématographiques sur les plongeurs de l’Oued Righ et d’Ouargla
Authors: Bodiot Adrien
Published: October 2023

Avant la conquête coloniale, qui conduisit à la mise en oeuvre d’un projet de forage à grande échelle, les oasis algériennes étaient le théâtre des exploits des rhetassin, des plongeurs spécialisés dans l’aménagement et le désengorgement des puits. La présente étude revient sur le destin culturel de ces figures atypiques en explorant un corpus large : des textes des savants arabes médiévaux – Ibn Khaldun notamment – aux récits des voyageurs et géographes français durant la colonisation jusqu’à la réappropriation de ces figures par Tahar Hanache dans le premier film du cinéma algérien et par Sven Lindqvist dans un récit de voyage plus récent. L’article fait l’hypothèse que les plongeurs révèlent le regard de ceux qui les observent : le « sens » écologique et politique de leur pratique n’est réellement saisi que par de rares artistes.
Writing against extraction: Petroleum resistance in Sony Labou Tansi’s Je,
soussigné cardiaque
Authors: Vessier Ninon
Published: October 2023

This paper analyses the presence of petroleum in the 1977 play Je,
soussigné cardiaque by Congolese writer Sony Labou Tansi. The play relates
petroleum extraction led by the Spanish colonist Perono in the imaginary country of
Lebango. The main character, Mallot, is a new teacher in town. He is accompanied by
his pregnant wife and their young daughter. Mallot realizes that Perono rules over
this petro-imperial tyranny, where the Lebangolese ecosystem is shaped and voided by
resource exploitation. My reading focuses on the presence of petroleum beyond an
anthropocentric perspective that sees it only as a resource, as I argue that
petroleum offers new possibilities of nonhuman resistance to
extraction.
« Pyrocène » ou « apocalypso » : les profonds angolais à l’épreuve de la pétro-magie dans O desejo de Kianda de Pepetela (1995) et Os transparentes d’Ondjaki (2012)
Authors: Boulanger Dorothée
Published: October 2023

Écrits à près d’un quart de siècle d’intervalle, O desejo de Kianda de Pepetela et Os transparentes d’Ondjaki décrivent tous deux l’emprise de la « pétro-magie » sur la capitale angolaise, Luanda, et ils annoncent la revanche des forces plus-qu’humaines tapies dans les sous-sols luandais. Dans le récit de Pepetela, le soulèvement des profonds est illustré par la figure de Kianda, l’esprit des eaux. Dans le roman d’Ondjaki, les nappes de pétrole cachées dans le sous-sol luandais entraînent des excavations destructrices, évoquant un processus morbide d’auto-dévoration néo-libérale sous les yeux de la population défaite. Malgré leur dénouement antinomique sous le signe de l’eau (apocalypso) ou du feu (pyrocène), ces deux ouvrages participent d’un processus similaire de redécouverte des solidarités populaires, examinées à travers le prisme des cosmologies animistes et des nouvelles possibilités de coalitions inter-espèces.
Sarkopenia pada Lanjut Usia: Patogenesis, Diagnosis dan Tata Laksana
Authors:   Faculty of Medicine and Health, Sepuluh November Institut of Technology, Njoto Edwin Nugroho
Published: October 2023

‘Sarcopenia’ involves a progressive age-related loss of muscle mass and associated muscle weakness that renders frail elders susceptible to serious injury from sudden falls and fractures and losing their functional independence. This disease has a complex multifactorial pathogenesis, which involves not only age-related changes in neuromuscular function, muscle protein turnover, and hormone levels and sensitivity, but also a chronic pro-inflammatory state, oxidative stress, and behavioral factors – in particular, nutritional status and degree of physical activity. In the previous definition by the European Working Group on Sarcopenia in Older People (EWGSOP) in 2010, the diagnosis of sarcopenia requires the presence of both low muscle mass and low muscle function. Since the 2010 definition is difficult to be translated to clinical practice, the EWGSOP uses low muscle strength as the primary parameter of sarcopenia in the 2018 definition; sarcopenia is probable when low muscle strength is detected. A sarcopenia diagnosis is confirmed by the presence of low muscle quantity or quality. When low muscle strength, low muscle quantity/quality and low physical performance are all detected, sarcopenia is considered severe. According to the pathophysiological factors involved in the pathogenesis of sarcopenia, different treatment strategies against sarcopenia are resistance exercise training, increase essential amino acids intake, vitamin D supplementation for those with vitamin D deficiency, polyunsaturated fatty acids (PUFAs) supplementation, testosterone supplementation, angiotensin-converting enzyme inhibitor administration.
