Authors: Dortaj Hengameh , Dortaj Sareh , Pourentezari Majid
Published: September 2022

Henna plant (Lawsonia inermis L.) has unique properties and has long been used as an herbal remedy. In this study, polyvinyl alcohol (PVA) nanofibers containing henna extract in two different concentrations were studied to prepare a wound dressing using electrospinning. PVA polymer nanofibers using henna extract with two different concentrations of 3% and 6% were prepared by the electrospinning method. Human fibroblasts were cultured on these fibers and the mechanical and survival properties of the cells, as well as the antibacterial properties of henna were compared and evaluated. The results showed that by using of henna extract in PVA nanofibers, cell viability was significantly reduced (P≤0.05). However, the ability of nanofibers to water uptake and mechanical properties of fibers significantly increased with increasing concentrations of henna extract (P≤0.05). Nanofiber wound dressing with antibacterial properties of henna extract provides relatively fast and rapid wound healing ability. The resulting fibers are encouraging candidates for the development of improved bandaging materials.

Published: September 2022

Schizophrenia is a severe psychiatric condition that affects approximately 1% of the global population. Over the last decade, the efficacy of berberine as a complementary therapy in psychiatric diseases without significant side effects has been demonstrated. Therefore, this study assessed the effect of alkaloid berberine on the positive and negative symptoms in patients with schizophrenia. From December 2020 to March 2021, a total of 86 patients with schizophrenia who were referred to Shiraz Ebne Sina Hospital in South of Iran were divided into two groups; 42 patients with schizophrenia in the placebo group received risperidone at a dosage of 4-6 mg per day, and 44 patients in the treatment group, in addition to risperidone, received berberine at a dosage of 500 mg per day. This treatment regimen was followed for 30 days. The Positive and Negative Syndrome Scale (PANSS) was used to assess the patients’ symptoms. According to data analysis, The PANSS score in both groups showed a statistically significant decrease after 30 days (p < 0.05); however, this decreasing trend was not statistically significant between the groups (p > 0.05). The current study showed that complementary use of alkaloid berberine capsule with a dose of 500 mg per day did not show better outcomes compared with the placebo in patients with schizophrenia.

Published: September 2022

COVID-19 spread rapidly around the world from the end of 2019. Hot footbath is a simple ancient technique, which has been used to alleviate many disorders. We aimed to investigate the effect of hot footbath in hospitalized COVID-19 patients. This open-label randomized controlled trial was conducted in Iran with allocation ratio of 1:1, with final sample size of 35 patients in each group. The intervention group received hot footbath (immersion of feet into the hot water at 42 °C, 10 cm above the ankles for 20 minutes, and then kept warm for 5 minutes) once a day for a week, in addition to the conventional therapy. The control group received only the conventional therapy; the primary outcomes evaluated were fever, respiratory rate, cough, fatigue, and myalgia; whereas admission rate, ICU admission, and mortality were assessed as the secondary outcomes. Except for cough intensity, cough frequency and fatigue (p value < 0.05), no significant differences were observed between the two groups in the primary and secondary outcomes. No adverse events were reported. Hot footbath can be used as a non-invasive, highly acceptable, and complementary technique to alleviate COVID-19 patients without any needs to expensive or special equipment; nevertheless, further studies with larger sample sizes are needed so as to accurately evaluate the effectiveness of hot footbath on clinical symptoms of COVID-19.

Published: September 2022

The present work documents indigenous knowledge of plants as a natural remedy by the inhabitants of Pushprajgarh tehsil, District Anuppur in Madhya Pradesh, Central India. This study was conducted by following standard ethnobotanical methods. Questionnaires, informal meetings, and group conversations with pre-identified informants were used to collect knowledge on medicinal plants. The present investigation documented 98 plant species belong to 51 families and 90 genera. The Fabaceae family, which includes 10 species, comprises the most of medicinal plants. Habit analysis of medicinal plants uncovered that trees represented the most proportion of 39 plant species (39.79%) and that decoction (boiling) was the most popular technique of preparing traditional medicines from plant material (44.34%). The highest informants' consensus factor (ICF) was accounted for the urinary disorder (0.60), and the highest outcome was recorded for the microbial infection (20.25%). The fidelity level (FL) results for 10 significant plant species were ranged from 40.86% to 75.00%.  Most of the plants have had a use value, ranging between 0.25 to 1, hence a constant use value for the most referred species is one. The frequency of citation (FC) of the selected plant species was found to be in the range of 1.85 to 6.48 and the relative frequency of citation (RFC) was found to be in the range of 0.04 to 0.12. Statistical analysis shows that current knowledge is still viable and facilitates conserving important plant species before much is lost. This study will provide basic information for further phytochemical/ pharmacological research to explore potential lead molecules for new drug development and discovery process from natural products.

Integracija evropskih narodov ali združene države Evrope s pogleda Spinellija in Moneta v kontekstu federalizma in demokracije
Authors: MARGAN FLORIAN
Published: September 2022

Načrt za izgradnjo "Združenih držav Evrope" bi morala temeljiti na demokratičnih načelih. V nasprotnem primeru nikoli ne bo privlačna za države, regije in državljane. Dokler se v EU ne uveljavijo temeljna načela demokracije, je vsaka razprava o nadaljnji integraciji držav članic bistveno nesmiselna. Če pogledamo institucionalni razvoj ES/EU, ni jasno, da bi ta razvoj v celoti sledil na osnovi mišljenja Monnetija, vendar so bili njegovi koraki postopnosti bližje dejanskemu razvoju EU, kot Spinellijev konstitucionalizem. Potrebujemo več svobode in demokracije v Evropi suverenih držav (če bo v to smer potekala politika), ter manj predpisov in nekje, nesmiselnih regulacij.

Published: September 2022

Le cacao représente 10 à 15% du Produit Intérieur Brut (PIB) de la Côte d’Ivoire, avec près de 40% de ses recettes d’exportation. Il est la principale source de revenus de près de 800 000 ménages de producteurs. Cependant, le secteur cacaoyer ivoirien est confronté à de nombreux problèmes qui constituent des pesanteurs à son bon développement. Cet article, mené à l’échelle du territoire de la sous-préfecture de Soubré (sud-ouest de la Côte d’Ivoire), analyse la traite cacaoyère et sa pesanteur majeure qu’est l’insécurité causée par les actes criminels. Il s’appuie sur une recherche documentaire et une enquête de terrain auprès d’acteurs tels les producteurs, les coopératives et les forces de sécurité. Il est fondé sur une théorisation de l’environnement sécuritaire de la traite cacaoyère pour aboutir à trois principaux résultats. Ces résultats indiquent d’abord que la traite cacaoyère cristallise essentiellement deux types de flux, impulsés par les activités des acteurs. Ensuite, des facteurs divers concourant à l’installation d’une atmosphère d’insécurité. Enfin, d’une campagne à l’autre, les actes d’infractions connaissent une évolution en fonction de l’intensité des activités commerciales autour de la production du cacao.

Le bassin versant de Ogo est touché par les aléas climatiques et fait face à des défis écologiques et environnementaux considérables (montée de la désertification). Les terres agricoles sont devenues de plus en plus fragiles du fait de l’érosion hydrique. Dans cet article, la morphodynamique hydrique est étudiée par des mesures de terrain à différents sites sur des parcelles d’expérimentation. Les mesures sur les parcelles d’érosion entre 2015 et 2017 ont montré une forte variabilité des taux de ruissèlement et d’érosion entre les sites observés. Cette variabilité est liée à la pluviométrie et au type de sol. Les coefficients de ruissellement varient entre 0,8 et 0,25 sur les sites d’observation (Thiankone Hiraye, Mbélone et Danthiady). L’érosion sur les parcelles sont estimées à 18,7 tonnes par hectares en 2015, 13,4 t/ha en 2016 et 14,95 t/ha de pertes en terre en 2017.

Tutoring is a process of providing learning assistance to students from elementary school to high school. One of the tutoring institutions in Jember Regency is Griya Belajar Pintar Arrava. Arrava always tries to provide the best services and facilities for its students by providing quality teachers. Qualified teachers can be obtained through a good teacher selection process. However, Arrava's leader, who also serves as a decision maker, always has difficulty in choosing new teachers. Efforts that can be made to overcome these difficulties are by building a decision support system for teacher selection. The decision support system for teacher selection can assist Arrava leaders in selecting qualified teachers by providing applicant recommendations based on the results of system calculations. One method that can be used in the selection of teachers is the Promethee method. Promethee is a method that is able to solve problems in determining the order (priority). Basically the Promethee method compares the scores between alternatives (applicants) based on each criterion, resulting in a more accurate decision. The results of this study indicate that the applicant who is ranked first is Nur Khotimah with a value of 0.362014, the second is Hendra Setiawan with a value of 0.245347, the third is Miftahul Arifin with a value of 0.000833, the fourth is Novi Ekasari with a value of -0.3025, and the fifth is Nurul Azizah with a value of -0.30569.

ResumenEl entendimiento tradicional de los entornos urbanos consolidados como entidades netamente disociadas de las realidades periurbanas ha sido revisado desde hace décadas. La interacción controlada de las realidades urbanas y periurbanas se manifiesta claramente como una de las palancas más eficaces de regeneración urbana. Para tratar de aprehender la compleja dinámica de esos paisajes urbanizados situados junto a los límites de la ciudad compacta, contar con renovadas herramientas ágiles y solventes se convierte también en un apasionante reto en el proyecto y gestión de los espacios urbanos.  La comunicación presenta los procesos y las particularidades de dos espacios periurbanos de la ciudad de Zaragoza, ubicados al oeste y al este de la ciudad, en el eje del río Ebro, elemento natural configurador del territorio y de la ciudad a lo largo de su historia. La condición natural de las distintas terrazas del valle del Ebro en el punto de la confluencia de los ríos Gállego y Huerva determinó los espacios para los distintos emplazamientos y actividades urbanas. De esta forma, la condición inundable de los territorios circundantes, así como las distintas líneas de defensa contra las avenidas del Ebro, han determinado las aptitudes para el desarrollo urbanístico de las distintas piezas que conforman el entorno metropolitano de Zaragoza.  La comunicación profundiza en las dinámicas espaciales y en las tensiones sociales presentes en estos dos territorios periurbanos de Zaragoza, y realiza un repaso a los procesos que han tenido incidencia en la forma actual de estos espacios periurbanos. Finalmente, se detectan oportunidades de carácter estratégico y se plantean acciones conjuntas para la regeneración de los espacios urbanos consolidados y para el refuerzo de los valores ecológicos y culturales de los espacios agrícolas y fluviales del entorno este y oeste de Zaragoza

Systems genetics is key for integrating a large number of variants associated with diseases. Vitamin K (VK) is one of the scarcely studied conditions in lieu of ascertaining either the differentially expressed genes (DEGs) or variants in an individual subpopulation of diseased phenotypes associated with VK, viz. myocardial infarction, renal failure, prostate cancer, thrombosis, thrombocytopenia, coagulation related diseases to name a few. In this work, we have screened characteristic DEGs common to three VK-related diseases, viz. myocardial infarction, renal failure and prostate cancer and asked whether or not any DEGs in addition to pathogenic variants are common to these conditions. We attempt to bridge the gap in finding characteristic biomarkers and discuss the role of long noncoding RNAs (lncRNAs) in the biogenesis of VK deficiencies.

Pineapple is a highly demanded fruit in international markets, thanks to its unique appearance and flavor, high fiber content, vitamins, folic acid, and minerals. It makes the pineapple production and processing market a significant source of income for producing countries, such as Costa Rica. Nowadays, its processing produces a large amount of waste with negative consequences for the environment. However, pineapple waste is an essential source of cellulose, hemicellulose, lignin, and other high-value products like enzymes (bromelain). These by-products can be obtained by pineapple waste biorefinery, generating an additional source of export goods and foreign currency, framing pineapple processing in the concept of the circular economy. This review discusses how incorporating biorefinery in the pineapple production processes can contribute to the post-COVID 19 economy in Costa Rica. Pineapple production in Costa Rica is explored, and the contamination of generated residues is delineated. Furthermore, the primary processes for by-product extraction via biorefinery, their general characteristics and applications in the medical field, and their contribution to the circular economy are presented.

Published: September 2022

So that the levels of water stress are not harmful to the development of the crop and affect its productivity, its detection and monitoring are necessary, and it can occur in different ways. One of them is through the Crop Water Stress Index (CWSI). This index quantifies water stress through the normalization of leaf temperature between the maximum and minimum plant temperatures as a function of evaporation conditions. The responses of a low-cost infrared (IR) sensor were crossed with image processing through segmentation by the Excess Green model to develop a water stress detection system using CWSI. A soil/plant temperature map was generated through a point-to-point scan of the IR sensor. And when it overlaid with a segmented image of the experimental area, only points identified as plants had their temperature values maintained. The Non-Water-Stressed Baseline (NWSB) equation was parameterized for the same conditions of the experiment and external environmental. The experimental area was divided into three different treatments, maintained under stable water conditions throughout the experiment and the system was able to identify stably different stress values between treatments. Although the relationship between crop and environment affected the results, this work showed that using an irrigation system based on CWSI is possible.

Published: September 2022

In the present study we report the efficacy of food matrices derived from olives in preventing oxidation of low-density lipoprotein cholesterol (LDL) and lipid peroxidation. To this end, 12 healthy volunteers were divided into 3 groups and cross-received a single dose of olive phenolics, mainly hydroxytyrosol (HT), provided as a liquid dietary supplement (30.6 or 61.5 mg HT), or as fortified extra virgin olive oil (12.19 mg HT + tyrosol). Blood and urine samples were collected at baseline and up to 12 hours after ingestion. Plasma oxidized LDL levels were measured by ELISA using a monoclonal antibody, while F2-isoprostanes were quantified in urine by UHPLC-MS/MS. Despite the great variability between individuals, a tendency to reduce lipoxidation reactions has been observed after olive phenolics intake in both, blood and urine. In addition, the subgroup of individuals with the highest baseline lipoxidation level showed a decrease in F2-isoprostanes (p < 0.05) after taking the food supplements, as well as a marked decrease in oxidized LDL levels (p < 0.01) after intake of the food supplement with the lowest HT dose. These promising results suggest that HT supplementation could be a useful aid in preventing lipoxidation. Additionally, people with a redox imbalance could benefit even more from supplementing with bioavailable HT.

In recent years, solid state terahertz (THz) modulators have obtained rapid progress with the widespread use of two-dimensional (2D) materials in the field of THz; however, challenges remain in preparing flexible THz modulators. In this study, flexible ferromagnetic nematic materials were prepared by doping thermotropic nematic liquid crystals 5CB into magnetic fluids, and the influence of hydrogen bonding in water was reduced by a self-made cyclic olefin copolymer (COC) microfluidic chip. THz modulation characteristics of magnetic fluid and ferromagnetic nematic liquid crystal (FNLC) under the induction of external magnetic field were compared using a THz time domain spectroscopy system. Under the action of a 91 mT magnetic field, the magnetic fluid has a maximum modulation depth (MD) of 54%. Under the same magnetic field, the maximum MD of the ferromagnetic nematic liquid crystal materials increase to 78% because of the rearrangement of Fe3O4 nanoparticles induced by the topological defect of the liquid crystal. We demonstrate that the magneto-optical effect is significantly enhanced in the ferromagnetic nematic liquid crystal hybrid system. This strategy of doping thermotropic nematic liquid crystals to enhance the magneto-optical effect has great potential for THz filtering, modulation, and sensing applications.

Since the 1990s, mobile telecommunication networks have gradually become denser around the world. Nowadays, large parts of their backhaul network consist of commercial microwave links (CMLs). Since CML signals are attenuated by rainfall the exploitation of records of this attenua-tion for precipitation monitoring purposes is an innovative and inexpensive solution. Performance data from mobile operators' networks is crucial for the implementation of this technology. And, moreover for near real-time quantification. To meet this requirement, a real-time system for col-lecting and storing CML power levels from the cellular phone operator "Telecel Faso" in Burkina Faso was implemented. This new acquisition system, which uses the Simple Network Manage-ment Protocol (SNMP) can simultaneously record the transmitted and received power levels from all the CML to which it has access, with a time resolution of one minute. Installed at “Laboratoire des Matériaux et Environnement de l’Université Joseph KI-ZERBO (Burkina Faso)”, this acquisi-tion system is dynamic and has gradually grown from eight to more than 1000 radio links Tele-cel Faso CML links between 2019 and 2021. The system covers the capital Ouagadougou and the main cities of Burkina Faso (Bobo Dioulasso, Ouahigouya, Koudougou and Kaya) as well as the axes connecting Ouagadougou to these cities.

In the context of Covid-19 virus containment, there is a lack of acceptance of preventive measures in the population. The present work investigated which factors influence the belief in of scientific propositions compared belief in conspiracy theories. The focus here was on the determinants of conspiracy beliefs in the context of Covid-19 related media content. Using an online questionnaire (N = 175), results indicate that scientific compared to conspiracy theoretical media content led to higher acceptance. Furthermore, Need for Cognition (NFC-K), a conspiracy theoretical worldview (CMQ), and openness to experience (NEO-FFI) were positively associated with conspiracy beliefs derived from Facebook postings. In addition, a conspiracy theoretical worldview was negatively associated with belief in scientific media content. Furthermore, agreeableness was unrelated to conspiracy beliefs, although it was positively associated with conspiracy theoretical worldview. The results imply promising persuasion strategies for reducing conspiracy theoretical beliefs and to increase the acceptance of preventive measures.

The Sulfur Dioxide (SO2) compound is a primary environmental pollutant worldwide, whereas elemental Sulfur (S) is a global commodity possessing a variety of industrial as well as commercial functions. The chemical relationship between poisonous SO2 and commercially viable elemental S has motivated this investigation using Density Functional Theory calculation of the relative transition state barriers for the 2-step Dehydro-sulfurization oxidation-reduction reaction. Additionally, doubly-charged nanoscale platelet Molybdenum Disulfide (MoS2), Armchair (6,6) Carbon Nanotube, 28-atom Graphene nanoflake (GR-28), and Fullerene C-60 are utilized as catalysts. The optimal heterogeneous and homogeneous catalysis pathways of the 2-step oxidation-reduction from SO2 to elemental S are further inspired by the biomimicry of the honeybee species multi-step bio-catalysis of pollen conversion to organic honey. Potential applications include environmental depollution, the mining of elemental sulfur, and the functionalization of novel technologies such as the recently patented aerial and amphibious Lynchpin TM drones.

Published: September 2022

In the speed control system of Interior Permanent Magnet Synchronous Motor (IPMSM) without a speed sensor, the speed under the traditional PI control suffers from poor tracking performance and step response overshoot. This paper proposes a Compound Variable Structure PI (CVSPI) controller to improve the system control performance. It can choose whether to include an integral term according to the size of the system deviation to speed up the response. It also introduces a Model Reference Adaptive System (MRAS) speed observer in the controller to estimate the speed and adaptively adjust the size of the anti-integration saturation gain to improve the dynamic response following performance and immunity of the system. A feed-forward link is added for a given input differential to achieve an accurate answer to time-varying inputs. As the linear compensation matrix of the conventional MRAS is a unit matrix, the speed can only be accurately observed in a specific speed range. In this paper, a new linear compensation matrix is designed, and a new speed adaptive law is derived, allowing the improved MRAS to measure speed over a wide range accurately. Simulation results validate the excellent control performance of the CVSPI and the accuracy of the enhanced MRAS over a wide speed range.

The addition of prebiotics is one of the most important ways to improve the techno-functional properties of bread. In this study, the effects of resistant starch, polydextrose, and inulin on the wheat flour, dough, and bread properties were investigated. In farinography results, resistant starch significantly increased the development time (2:18) with a boosting effect, but polydextrose (1:48) and inulin (1:36) weakened the dough (P <0.05). Inulin, polydextrose, and resistant starch had the most effect on reducing water absorption (40, 43.2, and 48.9) respectively (P <0.05). According to extensography data, inulin had the best result in baking compared to other polysaccharides. In terms of baked breads, samples containing resistant starch had high moisture that could be due to starch gelatinization and moisture-retaining, which delays the staling process of bread. Inulin, polydextrose, and resistant starch prebiotic ingredients affected dough rheological properties and bread quality, and organoleptic characteristics, however, resistant starch was the best.

Published: September 2022

The use of digital twins for the development of Autonomous Maritime Surface Vessels (AMSVs) has enormous potential to resolve the increasing need for water-based navigation and safety at the seas. Aiming at the problem of lack of broad and integrated digital twin implementations with live data along with the absence of a digital twin-driven framework for AMSV design and development, an application framework for the development of a fully autonomous vessel using an integrated digital twin in a 3D simulation environment has been presented. Our framework has four layers to ensure that the simulation and the real-world boat as well as the environment are as close as possible. Åboat, an experimental research platform for maritime automation and autonomous surface ship applications, equipped with two trolling electric motors, cameras, LiDARs, IMU and GPS has been used as the case study to provide a proof of concept. Åboat and its sensors, alongwith the environment have been replicated in a 3D simulation environment. Using the proposed application framework, we develop obstacle detection and path planning systems based on machine learning which leverage live data from a 3D simulation environment to mirror the complex dynamics of the real world.

Tear Size and Stiffness Are Important Predictors of Retear
Authors: Guo Allen A. , Stitz Daniel J. , Lam Patrick , Murrell George A.C.
Published: September 2022

Background:

This study aimed to identify whether early postoperative shoulder stiffness is associated with improved healing following rotator cuff repair, and if so, how this factor might interact with other factors known to affect rotator cuff repair integrity.

Methods:

We conducted a retrospective analysis of prospectively collected data from 1,526 primary arthroscopic rotator cuff repairs. Six-week range of motion was assessed to determine shoulder stiffness, and repair integrity was evaluated at 6 months by ultrasound. Multiple logistic regression analysis was used to identify variables that affected retear, and receiver operating characteristic (ROC) curve analysis was used to evaluate predictive thresholds for retear.

Results:

Tear-size area was the most accurate predictor of retear (area under the curve [AUC] = 0.77; 95% confidence interval [CI] = 0.72 to 0.81), followed by 6-week passive external rotation (AUC = 0.67; 95% CI = 0.63 to 0.72), 6-week passive forward flexion (AUC = 0.67; 95% CI = 0.62 to 0.72), age (AUC = 0.65; 95% CI = 0.60 to 0.70), tear type (partial-thickness versus full-thickness) (AUC = 0.65; 95% CI = 0.61 to 0.69), and hospital type (public versus private) (AUC = 0.43; 95% CI = 0.37 to 0.49). Patients with smaller tears, reduced 6-week passive external rotation, reduced 6-week passive forward flexion, younger age, partial-thickness tears, and operations performed in a private day surgery or hospital setting were more likely to have an intact rotator cuff repair at 6 months. The AUC of this curve was 0.84 (95% CI = 0.80 to 0.87), which indicates that this combination of factors can accurately predict 84% of retears. Reduced range of motion at 6 weeks was associated with improved repair integrity for patients with tears of >1 to 6 cm2; however, this effect was less pronounced in tears of ≤1 cm2 or >6 cm2.

Conclusions:

Early postoperative stiffness following arthroscopic single-row, inverted-mattress rotator cuff repair at 6 weeks was associated with an intact repair at 6 months. The protective effects of postoperative stiffness and tear size were additive. The chance of retear in patients with a tear of ≤1 cm2 and external rotation of ≤27° at 6 weeks was 1%, while those with tears of >6 cm2 and external rotation of >27° had a 40% chance.

Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

The Bhil, Bhilala, Barela and Patelia form the second largest tribal group in India after the Gonds, which is consisted of 45 sub-groups, according to the 2011 Census (Census of India 2011). The Bhil tribe has itself various sub-groups besides these three other tribal groups which have been clubbed with the Bhil tribe in Madhya Pradesh. The Bhil and the related tribes have their major concentration in the adjoining states of Madhya Pradesh, Rajasthan, Gujarat and Maharashtra which form the Malwa region. Malwa covers the whole of Bhil country, excepting some adjoining portions of Gujarat, which has a considerably large population of Bhil and related tribes. The population of the Bhil, Bhilala, Barela and Patelia in Madhya Pradesh is 59,93,921. The districts which were having more than one lakh Bhil population are Dhar (1200502), Barwani (952940), Jhabua (889582), West Nimar (713640), Alirajpur (647653), Ratlam (410992), East Nimar (230857), Indore (195663), Burhanpur (142179), Dewas (136289), and Guna (116239). The focus of the study is on the Bhilala tribe who inhabit largely in the districts of Dhar and Barwani. Although, they have been clubbed with the Bhil tribe, they have their own identity and there is a process of Rajputization among them. The Bhilala assume superiority than other groups in the local milieu of the tribes living there and claim to be the Rajputs. Hence, understanding of this tribal group can be made in the local perspective and their historical background in the present day situation. It is one of the progressive tribes of India.
Evolution of Ethics Frameworks in the Oil and Gas Organizations and Professional Societies
Authors: Capello Maria Angela , Howes C. Susan
Published: September 2022

The term "ethics" as a set of rules is used in the professional world as well as in professional societies to establish what is acceptable or not, in terms of ethical professional behavior. This paper explores how the practices and codification of practices related to professional practice have evolved in the Oil and Gas sector, with emphasis on professional societies.

The analysis was performed summarizing the history of ethics in general, as applicable to the Oil and Gas sector. Then, research was conducted on how the several important corporations in the upstream or downstream of oil and gas initiated and evolved their own ethical codes. We also explored how the academic world has engaged in issuing Codes of Ethics that govern the behavior of both students and faculty members at the institutional and department level. A special emphasis was placed in the investigation of the evolution of the Code of Ethics of the main professional societies and organizations related to the Oil and Gas Sector, centered on SPE, and including AAPG (the American Association of Petroleum Geologists), SEG (the Societu of Exploration Geophsyicists), EAGE (the European Association of Geoscientists and Engineers) and other relevant ones.

The conclusions point to a realization that the ethical codes analyzed evolved, following societal changes, in relation to under-represented groups in terms of gender, race, nationality, age, religion and ethnicity, as well as in relation to the expansion of the industry to more and new geographical areas. Currently, almost all organizations and professional societies have a Code of Ethics that profiles their main values and sets a frame for what is or not appropriate in advancing their activities. The Code of Ethics were gradually expanded, spelling out further specific rules, often called "Statements" like "Sexual Harassment," "Bribery" and "Human Rights" statements, aiming to address a variety of specific issues. The Code of Ethics, along the specific self-disclosure statements, are the ethical framework of organizations in Oil and Gas for guiding employees and stakeholders towards:

– Alignment with Corporate and/or Academic Values. – Clarification of the Value Proposition for employees and/or prospective students. – Response to societal trends like "MeToo," "BlackLivesMatter," and others. – Rejection of modern issues affecting some industrial segments like Modern Work Slavery. – Enhancement of the corporate prestige and rankings in ESG (environmental, Society and Governance) grounding disclosures useful for investment decisions

Our paper is a contribution to share information and raise our collective awareness in the profession about what is the current practice in Oil and Gas regarding Codes of Ethics of Corporations and Professional Societies, how they have evolved, and what are the current and future challenges and opportunities, to expand solid and useful ethics frameworks in the context of the present rapid social transformation.
