Les marchés de la téléphonie mobile en Afrique de l’Ouest : dynamiques populaires et stratégies des firmes globales
Authors: Dembélé Abdul-Aziz
Published: November 2023

Cet article étudie le commerce des produits électroniques grand public, principalement les téléphones mobiles et leurs divers accessoires, sur un lieu marchand : le marché Tecno dans l’agglomération abidjanaise (Côte d’Ivoire). Alors que ces types de commerces sont généralement appréhendés selon une approche de la mondialisation par le bas, le cadre analytique que nous proposons les envisage dans la perspective d’une co-construction : c’est-à-dire à la fois comme produits des capacités d’initiatives des acteurs populaires mais aussi comme des manifestations locales de stratégies déployées par les firmes globales de la téléphonie qui ont compris l’intérêt qu’elles ont à investir et exploiter ces espaces où s’approvisionne la majeure partie de la population urbaine. L’intervention directe et pour le moins originale d’une firme globale – Samsung – sur le marché Tecno est ainsi analysée à la lumière de son articulation aux logiques plurielles d’acteurs populaires. Cet article montre ainsi une convergence d’intérêt entre acteurs globaux et acteurs populaires autour d’un objectif commun : vendre au plus grand nombre.

Published: November 2023

Cerebral stroke is the second leading cause of death and the third leading cause of death and disability in the world, and more than half of these patients have hand dysfunction, making hand rehabilitation an urgent challenge. In this study, a system for hand rehabilitation therapy for stroke patients was designed using novel human-computer interaction technology. The system combines a brain-computer interface, a deep learning algorithm and a rehabilitation glove, and designs an electroencephalogram (EEG) signal acquisition card and a rehabilitation glove to realise the application of motor imagery therapy to the active rehabilitation of patients' hands. On the brain-computer interface-based motor imagery experiments, the Long Short Term Memory (LSTM) recurrent neural network algorithm designed in this study achieves an average accuracy of 95.78% for the classification accuracy of mental tasks in seven motor imagery modes, which is important for the active rehabilitation of patients with hand function based on motor imagery-driven rehabilitation.

Authors: Eglit Margarita Ernestovna , Drozdova Yulia Aleksandrovna , Usachev Ilya Nikolaevich , Drozdov Aleksander Vladimirovich
Published: November 2023

Рассматриваются ламинарные течения жидкостей, обладающих пределом текучести, в трубах под действием периодически меняющегося перепада давления. Для описания реологических свойств движущихся жидкостей принимается модель Хершеля-Балкли. Численно исследуется влияние пульсаций перепада давления на профили скорости, а также на средние по периоду величины расхода, трения на стенках трубы и толщины "квазитвердого" ядра в зависимости от амплитуды и частоты колебаний перепада давления, обобщенного числа Бингама и степенного индекса. Показано, что в потоках вязкопластических жидкостей с величиной степенного индекса, большей единицы, влияние пульсаций перепада давления качественно различно в разных диапазонах величин скорости сдвига. Исследованы потоки, в которых относительные амплитуды колебаний перепада давления велики. При больших амплитудах и малых частотах колебаний перепада давления в потоке периодически возникают противотечения и образуются не одна, а две зоны "квазитвердого" течения, а также периодически появляются конечные интервалы времени, на которых расход равен нулю.
Периодические и уединенные волны и бездиссипативные структуры разрывов в электромагнитной гидродинамике в случае резонанса волн
Authors: Bakholdin Igor Borisovich
Published: November 2023

Описывается численный метод исследования периодических волн, уединенных волн и структур бездиссипативных разрывов для уравнений электромагнитной гидродинамики. Исследуется расположение ветвей периодических решений. Уединенные волны находятся как предельные решения последовательностей периодических волн, структуры бездиссипативных разрывов - как пределы последовательностей уединенных волн. Показано, что разрыв длинноволновой ветви быстрых магнитозвуковых волн не коррелирует с существованием перехода на короткую ветвь, чем обусловлено возникновение решений хаотического типа при отсутствии диссипации. Исследование медленных магнитозвуковых волн показало, что при малых и умеренных амплитудах есть решение, близкое к уединенной волне. Выявлены приближенные уединенные волны гибридного типа, представляющие собой комбинации альвеновской и медленной магнитозвуковой волн.

EFFECTIVENESS OF DWIHARIDRA RASAKRIYA PICHU IN CHRONIC FIS-SURE-IN-ANO - A SINGLE GROUP CLINICAL STUDY
Authors: P Bijuna , P. V Sunitha
Published: November 2023

Fissure-in-ano is an elongated ulcer in the long axis of the lower anal canal. One in every ten people is affected by anal fissure in their lifetime. It occurs equally in both sexes and is mostly seen between 30-50 years of age. Sometimes it occurs in children also. Constipation is the primary and sole cause of initiation of a fissure-in-ano. Passage of hard stool, irregularity of diet, consumption of spicy and pungent food, faulty bowel habits, and lack of local hygiene can contribute to initiation of the pathology. Fissure-in-ano is of two types, acute and chronic. If a fissure is present for more than six weeks, it is termed a chronic fissure. In Ayurveda it may be correlated with Parikaṛthika. Pichu dhārana was found to be effective in chronic fissure-in-ano. The aim of this study is to find out the effectiveness of Dwiharidra rasakriya pichu in the management of chronic fissure-in ano.

Published: November 2023

The article reveals the essence of the process of digitalization of the economy of Ukraine in the conditions of growing threats from the external environment, which is connected with the formation of an open economic system and deep transformational ties in global economic relations. Economic relations in the intellectual sphere, which are connected with the innovative activities of Ukrainian enterprises, are the object of attention of both international transatlantic companies and national structures, which are connected with the undermining of the competitiveness of the state and export-oriented enterprises, which ultimately leads to the limitation autonomy and independence of the state. Under such conditions, the importance of economic security and the formation of significantly new systems for the protection of intellectual resources of Ukrainian enterprises and the limitation of the ability to influence the modern information, telecommunications and modern communication systems of the country's enterprises, which can become the object of information attacks on the production infrastructure and the creation of threats, are sharply increasing for its existence.

This research investigates the chemical composition, total phenolic and flavonoid content, and antioxidant activity of acetone, methanol, and ethanol extracts of the lichen Umbilicaria grisea, and its major secondary metabolite, gyrophoric acid. The extracts were analyzed using high-performance liquid chromatography (HPLC-UV) and spectrophotometric assays. The results showed significant levels of phenolic compounds and flavonoids, which contribute to the lichen’s antioxidant potential. The antioxidant activity was evaluated using in vitro assays such as DPPH and ABTS radical scavenging activity. The extracts demonstrated potent antioxidant activity, suggesting their potential as natural antioxidants. The identification of bioactive compounds, high phenolic and flavonoid content, and significant antioxidant activity support the potential use of U. grisea as a natural source of therapeutic agents. Further studies are needed to elucidate the underlying mechanisms responsible for these biological activities and evaluate the efficacy and safety of these extracts for potential pharmaceutical applications.
Are We Ready For “Triplet” Therapy in Higher-Risk MDS?
Authors: Brunner Andrew M. , Platzbecker Uwe , DeZern Amy E. , Zeidan Amer M.
Published: November 2023

Higher-risk Myelodysplastic Syndromes/Neoplasms (MDS) represent an ongoing therapeutic challenge, with few effective therapies, many of which may have limited use in this older patient population often with considerations around comorbidities. Outside of transplant, azacitidine and decitabine remain the only disease-modifying therapies, and are palliative in nature. Recent interest has grown in extending combination chemotherapies used to treat acute myeloid leukemia (AML) to patients with MDS, including novel combination chemotherapy “doublets” and “triplets.” In this review, we discuss considerations around combination chemotherapy in MDS, specifically as relates to study design, appropriate endpoints, supportive considerations, and how to integrate these into the current treatment paradigm. New therapies in MDS are desperately needed but also require considerations particular to this unique patient population.

Pondok Pesantren Nurul Islam Pungging Mojokerto (NURIS) equips its santri with structured formal education. Problems are experienced when this boarding school has been productive in the field of education but is still passive in terms of economic independence. The potential to make boarding schools economically independent is very high. One is the creative economy, which is increasingly showing its intelligence in Industry 5.0. To catch up with this, it is necessary to empower santri to be able to become a santripreneur who has soft skills. One way is to empower students in the business incubator industry. The purpose of implementing santri empowerment activities is so that Nurul Islam Pungging Mojokerto boarding school can meet its own needs and become an economically independent modern boarding school. In addition to improving the pesantren's economy, this business incubator program is also expected to be a provision for students when they graduate to be able to live independently. This research uses a qualitative method by collecting data from in-depth interviews with several students, teachers, and the head of the boarding school foundation. After collecting the data, a Forum Group Discussion (FGD) was conducted, and determined the mechanism of this business incubator activity. Training and mentoring activities were conducted for Nurul Islam Pungging Mojokerto boarding school students for approximately 3 months. The design layout of the business incubator is the output of this research. As a business incubator, it is still not optimal. It needs to be improved regarding Shared, namely not providing office facilities that can be used together, and Synergy, namely not creating cooperation with parties outside the boarding school.

We study four expressions involving the integrals of Jacobi’s theta functions. From Poisson’s summation formula, we write the integrals of the functions θi, (i = 1,2,3,4) in terms of modified Bessel functions of the second kind. For the integrals of θ1 , θ2 and θ3, we get expressions with real arguments, but for the integral of θ4 , we find an expression with imaginary argument. In addition, we apply our results to the description of two kinds of interacting quantum systems: boson gas and fermion gas both under a thermal bath and an external magnetic field. PACS numbers:

The article presents studies to identify the greatest synergy effect for managing the sowing qualities of alfalfa seeds of variable Victoria with the use of neural network elements to control the dose of ultraviolet irradiation. The synergistic effect occurs when the seeds are simultaneously exposed first to ultraviolet radiation and then to a silicon-containing preparation of nanosilicon, or first to treatment with a preparation of NanoSilicon, and then to ultraviolet radiation. In both cases, changes in the sowing qualities of seeds were observed. The seeds were irradiated on a mobile LED UV irradiation unit using end-to-end digital energy-saving technologies with neural network elements to control the dose of UFOs with a VEML6070 digital sensor from the manufacturer Vishay Semiconductors. The TKS– ABC device measured the energy illumination of UV LEDs at a height of 70 mm, which showed that UV-A radiation is 95.67% at an average energy illumination of 3.137 W/m2, UV-B radiation is 3.41% at 0.112 W/m2 and UV-C radiation is 0.91% at 0.030 W/m2. The conducted studies have revealed that the greatest synergistic effect for managing the sowing qualities of alfalfa seeds occurs when alfalfa seeds are treated first with a nanosilicon preparation, and then with UFOs. As a result of the management of the sowing qualities of alfalfa seeds, which is involved in the implementation of the proposed sequence of pre-sowing seed treatment, an increase in laboratory germination was obtained by 6% at HCR05 – 4%; the length of the sprout up to 2.4 cm and the root up to 1.5 cm; the degree of development of seedlings up to 3.0 points and growth strength up to 29.8%.

Fractionation of stable carbon isotopes during formate consumption in anoxic rice paddy soils and lake sediments
Authors: Conrad Ralf , Claus Peter
Published: November 2023

Abstract. Formate is energetically equivalent to hydrogen and thus, is an important intermediate during the breakdown of organic matter in anoxic rice paddy soils and lake sediments. Formate is a common substrate for methanogenesis, homoacetogenesis and sulfate reduction. However, how much these processes contribute to formate degradation and fractionate carbon stable isotopes is largely unknown. Therefore, we measured the conversion of formate to acetate, CH4 and CO2 and the δ13C of these compounds in samples of paddy soils from Vercelli (Italy) and the International Rice Research Institute (IRRI, the Philippines) and of sediments from the NE and SW basins of Lake Fuchskuhle (Germany). The samples were suspended in phosphate buffer (pH 7.0) both in the absence and presence of sulfate (gypsum) and of methyl fluoride (CH3F), an inhibitor of aceticlastic methanogenesis. In the paddy soils, formate was mainly converted to acetate both under methanogenic and sulfidogenic conditions. Methane was only a minor product and was mainly formed from the acetate. In the lake sediments, the product spectrum was similar, but only under methanogenic conditions. In the presence of sulfate, however, acetate and CH4 were only minor products. The isotopic enrichment factors (εform) of formate consumption, determined by Mariotti plots, were in the low range of -8 ‰ to -2.5 ‰ when sulfate was absent and formate was mainly converted to acetate and CH4. However, no enrichment factor was detectable when formate was degraded with sulfate to mainly CO2. The δ13C of acetate was by about 25–50 ‰ more negative than that of formate indicating acetate production by chemolithotrophic homoacetogenesis. Hence, formate seems to be an excellent substrate for homoacetogenesis in anoxic soils and sediments, so that this process is competing well with methanogenesis and sulfate reduction.

Published: November 2023

Abstract. Glaciers are retreating globally and are projected to continue to lose mass in the coming decades, directly affecting downstream ecosystems through changes in glacier runoff. Estimating the future evolution of glacier runoff involves several sources of uncertainty in the modelling chain, which to date have not been comprehensively assessed on a regional scale. In this study, we used the Open Global Glacier Model (OGGM) to estimate the glacier evolution of each glacier (area > 1 km2) in the Patagonian Andes (40–56° S), which together represent 82 % of the glacier area of the Andes. We used different glacier inventories (n = 2), ice thickness datasets (n = 2), historical climate datasets (n = 4), general circulation models (GCMs; n = 10), emission scenarios (SSPs; n = 4), and bias correction methods (BCMs; n = 3) to generate 1,920 possible scenarios over the period 1980–2099. For each scenario and catchment, glacier runoff and melt on glacier time series were characterized by ten glacio-hydrological signatures (i.e., metrics). We used the permutation feature importance of random forest regression models to assess the relative importance of each source on the signatures of each catchment. Considering all scenarios, 61 % ± 14 % of the catchment area (30 % ± 13 % of glacier area) has already peaked in terms of glacier melt (year 2020), and 43 % ± 8 % of the catchment area (18 % ± 7 % of glacier area) will lose more than 80 % of its volume this century. Considering the melt on glacier signatures, the future sources of uncertainty (GCMs, SSPs and BCMs) were the main source in only 18 % ± 21 % of the total catchment area. In contrast, the reference climate was the most important source in 78 % ± 21 % of the catchment area, highlighting the importance of the choices we make in the calibration procedure. The results provide a basis for prioritizing future efforts (e.g., improve reference climate characterization) to reduce glacio-hydrological modelling gaps in poorly instrumented regions, such as the Patagonian Andes.
Derivation of Atmospheric Reaction Mechanisms for Volatile Organic Compounds by the SAPRC Mechanism Generation System (MechGen)
Authors: Carter William P. L. , Jiang Jia , Orlando John J. , Barsanti Kelley C.
Published: November 2023

Abstract. This paper describes the methods that are used in the SAPRC mechanism generation system, MechGen, to estimate rate constants and derive mechanisms for gas-phase reactions of volatile organic compounds (VOCs) in the lower atmosphere. Earlier versions of this system have been used for over 20 years in the development of the SAPRC mechanisms for air quality models and ozone (O3) reactivity assessments. This is the first complete documentation of MechGen as it currently exists. MechGen can be used to derive explicit mechanisms for most compounds with C, H, O, or N atoms. Included are reactions of stable compounds with hydroxy (OH) and nitrate (NO3) radicals, O3, O3P, or by photolysis or unimolecular reactions, and the reactions of the radicals they form in the presence of O2 and oxides of nitrogen (NOx) at atmospheric temperatures and pressures. Measured or theoretically calculated rate constants and branching ratios are used when data are available, but in most cases rate constants and branching ratios are estimated using various structure-reactivity or other estimation methods. Types of reactions that are estimated include initial reactions of organics with atmospheric oxidants or by photolysis, and unimolecular and bimolecular reactions of carbon-centered, alkoxy, and peroxy radicals and Criegee and other intermediates that are formed. This manuscript summarizes the capabilities of the MechGen system for deriving chemical mechanisms and the methods, assignments, and estimates used to derive them. Examples of MechGen predictions also are provided. Many of the estimation methods discussed here have not been published previously, and others have not been used previously in developing comprehensive mechanisms. This paper concludes with a discussion of the areas of uncertainty where additional measurements or theoretical estimates are needed and recommendations for future mechanism development and application.
Rate-induced tipping in ecosystems and climate: the role of unstable states, basin boundaries and transient dynamics
Authors: Feudel Ulrike
Published: November 2023

Abstract. The climate system as well as ecosystems might undergo relatively sudden qualitative changes in the dynamics when environmental parameters or external forcings vary due to anthropogenic influences. The study of these qualitative changes, called tipping phenomena, requires the development of new methodological approaches that allow phenomena observed in nature to be modeled, analyzed and predicted, especially concerning the climate crisis and its consequences. Here we briefly review the mechanisms of classical tipping phenomena and investigate rate-dependent tipping phenomena which occur in non-autonomous systems characterized by multiple timescales in more detail. We focus on the mechanism of rate-induced tipping caused by basin boundary crossings. We unravel the mechanism of this transition and analyze, in particular, the role of such basin boundary crossings in non-autonomous systems when a parameter drift induces a saddle-node bifurcation in which new attractors and saddle points emerge, including their basins of attraction. Furthermore, we study the detectability of those bifurcations by monitoring single trajectories in state space and find that depending on the rate of environmental parameter drift, such saddle-node bifurcations might be masked or hidden, and they can only be detected if a critical rate of environmental drift is crossed. This analysis reveals that unstable states of saddle type are the organizing centers of the global dynamics in non-autonomous multistable systems and as such need much more attention in future studies.
Brief communication: Alternation of thaw zones and deep permafrost in the cold climate conditions of the East Siberian Mountains, Suntar-Khayata Range

Published: November 2023

Abstract. The Suntar-Khayata Range includes numerous natural phenomena interacting with or depending on permafrost conditions. Here, we examine some patterns of deep permafrost and talik zones on adjacent sites. A 210 m deep borehole in siltstone bedrock was equipped for the temperature monitoring of the topmost 15 m and measurements of a deep permafrost temperature profile in July 2010. The temperature curvature in the upper part has a bend, which is consistent with the upper portion justified by climate warming, and shows a steady-state linear geothermal profile below 85 m depth with a high geothermal heat flux. A shallow borehole situated at the river floodplain was used to investigate the thaw zone's temperature regime. The temperatures down to 6.7 m deep have been monitored at 5 min intervals during heavy rainfall, and the temperature readings have behaved quite peculiarly. The thickness of the seasonal freezing layer reaches 5.7 m; moreover the ground temperature increases to 6 ∘C at 6.7 m depth by groundwater heat transfer. This study provides some new insights into the permafrost condition at one of the coldest places in the Northern Hemisphere.

Published: November 2023

Celem niniejszego szkicu jest przedstawienie historii diecezji poznańskiej i jej organizacji przez wieki. Diecezja poznańska miała początkowo bardzo rozległe terytorium, obejmując całą ówczesną Polskę. Wraz z powstaniem metropolii gnieźnieńskiej i biskupstw w innych miastach, jej obszar został zawężony. Wprowadzenie nowych diecezji i utrata terytoriów wskutek rozbicia dzielnicowego spowodowały zmiany w jej obszarze.  Artykuł ukazuje bogatą historię religijną i kulturową diecezji poznańskiej, począwszy od czasów chrztu Polski, aż po okres okupacji i odbudowę po wojnie. Warto podkreślić, że rozwinięcie kultu Najświętszej Maryi Panny, kultu świętych oraz różnych stowarzyszeń kapłańskich i bractw stanowiło istotny element życia religijnego w diecezji poznańskiej. Trudne czasy okupacji nie zdołały wygasić wiary i oddania duchowieństwa i wiernych. Diecezja poznańska przez minione wieki odgrywała ważną rolę w historii Kościoła w Polsce, a jej historia jest fascynującym przykładem, jak religia i duchowość kształtują życie społeczne i kulturalne regionu.

Clinical signs are often nonspecific and can easily be confused with other pathologies. Although acute, sub-acute and chronic forms have been described, the most common situation in equines is that of asymptomatic carrier, characterized by undetectable or extremely low parasitaemia and lack of clinical signs. Identification of the parasitic agent can be done both by direct methods and by molecular and serological methods. This study aims to identify the most commonly used diagnostic methods of EP with the highest specificity and sensitivity and the fewest limitations. In order to achieve the aim of this study, a systematic database search was carried out, resulting, after a preliminary selection, in a total of 97 publications considered eligible. It was concluded that molecular diagnostic methods can overcome many of the limitations of traditional methods and are essential to identify and distinguish genotypes of T. equi. Nonmolecular diagnostic methods may lack sensitivity and specificity, but they are still widely used and useful to support clinical and epidemiological research.

Hoop barns, the low input housing structures, can be used in housing horses during fall and winter seasons. One of the hoop structures issue is the level of temperature, which is close to environmental temperature. The aim of this study is to show some technological measures which can overcome the weaknesses of hoop structures such as: feeding strategy, water system and body warming of horses using IR film. The control variable was the skin temperature of six horses, repeatedly measured with FLIR® thermo camera during several levels of environmental temperature. In the study, by using IR heating film at outside temperatures such as 0, -5 and -10°C,  the body temperature measured in three body regions (neck, shoulder point and internal angle of eyes) did not differed significant (F=0.167 at p =0.847): without IR heating system, differences were observed (F= 8.905 at p =0.000). Moreover, in low BCS’s animals, below -10°C environmental temperature, in absence of IR heating and if less fiber was present in the diet, low critical temperature signs were observed. In conclusion the hoop structure can be used successfully in horses even when outside temperatures are below low critical temperature of horses if certain conditions are assigned such as: water at 10-15°C, additional hay for fiber, with or without infrared heating.

Assessing the behavior of a dog in a shelter is extremely important because the type of behavior can tell us if the animal can be given up for adoption, to whom it can be given up for adoption, if it cannot be given up for adoption and in which direction improvements in behavior need to be made to get it safely given up for adoption. This study aimed to assess the behavior of dogs in a public dog shelter by how a dog behaves towards a person (examiner) in a sequence of situations and to determine the number of individuals who responded with aggression. The behavior test was developed by The Rottweiler Rescue Society (Ontario, Canada) and John Rogerson, Blue Cross, Britain. Following minor modifications, has been used to examine dogs in public shelters. The test contains two additional assessment items from the article "An Evaluation of a Behavior Assessment to Determine the Suitability of Shelter Dogs for Rehoming" [1]. A total of 187 adult dogs were examined, of which 24 were identified with aggressive behavior and the types of aggression identified were dominance, interspecific, or territorial aggression.  No behavioral test can show specifically how a dog will behave in a new environment, but the information obtained from the examination can indicate extreme manifestations of canine behavior, such as dominance aggression, possessive aggression, territorial aggression, and separation anxiety.

The use of biomicro-needles, splinters derived from marine and freshwater sponges, is the subject of research worldwide. Their regenerative potential is due to their ability to form microchannels in the skin and persist for 72-120 hours. The study aimed to evaluate the effect of preparation based on biomicro-needles from the Spongilla spicules species on the skin parameters of women with visible signs of ageing. A significant improvement in skin hydration was demonstrated, as evidenced by a decrease in transepidermal water loss, an increase in hydration of the stratum corneum, or a statistically significant decrease in the echogenicity of the dermis. In addition, the thickness of the dermis increased significantly. A decrease in pH, an improvement in barrier function, and a visible reduction in hyperpigmentation,erythema, and wrinkles were demonstrated.
Barriers and benefits of breast cancer prevention programs in Poland

Breast cancer is the leading kind of malignancy among women in Poland. Mammography is recognised as a non-invasive diagnostic technique; yet, there exists a notable deficiency in the frequency of routine preventative screenings among Polish women. The aim of this research was to address the following inquiries: why there is a lack of widespread participation among women in Poland in cost-free tests that have the potential to save their lives, and what factors might motivate their engagement in preventative programmes. In order to achieve this objective, a survey was undertaken. The early detection of breast cancer significantly enhances the likelihood of achieving a full remission. Although most Polish women are aware that they can take a preventive test, still too few women take a mammogram. There is a need for modifications to be made in the precautionary screening system in order to enhance women’s motivation to engage in preventive care.
Quality of audit and cost stickiness empirical evidence from emerging markets
Authors: Raweh Nahla Abdulrahman Mohammed , Abdullah Abdulwahid Ahmed Hashed
Published: November 2023

This study aims to present further evidence of cost stickiness by employing Selling, General, and Administrative (SG&A) costs. It also provides empirical evidence on the effect of audit committee meetings and audit quality on cost stickiness. The study used data from listed companies on the Saudi Arabian stock exchange during 2015–2019. Based on pooled panel data regression, the study proves that the SG&A costs are sticky. The results show the level of SG&A costs increases more with an increase in sales revenue (activity) while it decreases less with an equivalent reduction in sales revenue (activity). Also, this study finds that the frequency of audit committee meetings decreases the magnitude stickiness of SG&A costs, which supports the view that frequent meetings of AC significantly enhance its overseeing function and effectiveness. The study further reveals that audit quality “by BIG4 audit firms” is not related to reduced cost stickiness. This result implies that there is no difference in CS between companies audited by BIG4 or by non-BIG4. In general, the research highlights the importance of AC diligence (i.e., meetings) in improving its effectiveness and controlling management’s discretions affecting the cost structure in the context of sticky cost behavior.
The food safety behavior of Jordanian restaurant managers and supervisors: A social cognitive theory-based perspective
Authors: Haddad Amany Khalaf , Ngah Abdul Hafaz
Published: November 2023

As foodborne diseases are current major health issues worldwide, food safety is a global health target. The present work has used social cognitive theory as theoretical support for examining the social and cognitive factors [outcome expectations (OE), self-regulation (SR), environmental determinants (ED), and self-efficacy (SE)] of Jordanian restaurant managers’ and supervisors’ food safety behavior (FSB). The moderator was willingness to comply (WC). Data were collected from the participants via Google Forms using purposive sampling methods. A total of 500 questionnaires were distributed, where 250 questionnaires were sent each to the Jordanian Restaurant Association (JRA, representing international and chain food restaurants in Jordan) as well as the Jordanian Union of Restaurants and Confectionary Proprietors (URCP, representing the local Jordanian restaurants). Two hundred and ninety-six completed questionnaires were returned. The hypotheses were analysed with smart partial least squares by structural equation modelling. The analysis determined that OE, SR, ED, and SE had positive impacts on FSB, while WC played a role in moderating the interlinkage among SE, OE, and FSB. To sum up, the current study as a whole also has significant theoretical and practical contributions for the practitioners in the given context.

Published: November 2023

This study aimed to investigate the impact of Environmental Education on sustainability and the mediating role of Environmentally Friendly Supply Chain Efficiency (EFSC) and Fostered Environmental Knowledge (FENK). Employing a quantitative approach, data were collected from supply chain professionals who participated in Environmental Education programs. The research findings indicate a positive relationship between Environmental Education and supply chain sustainability. The study revealed that Environmental Education significantly enhances EFSC and FENK and positively influences sustainability practices within supply chains. The implications of this research are twofold. Firstly, it underscores the importance of incorporating Environmental Education as a fundamental component of supply chain management, contributing to more environmentally responsible practices. Secondly, the study highlights the mediating role of EFSC and FENK, indicating that not only does Environmental Education directly impact sustainability but also through the enhancement of these mediating factors. This research offers a novel perspective by establishing the link between Environmental Education, EFSC, FENK, and supply chain sustainability. However, certain limitations should be acknowledged, such as the potential for response bias and the need for further research to explore other potential mediators. Nevertheless, this study provides valuable insights for practitioners and policymakers seeking to promote sustainability in supply chains by emphasizing the role of Environmental Education and its interconnectedness with EFSC and FENK.
