Organizational Socialization as Part of Knowledge Management
Authors: Anđelković Maja , Marjanović Marjan , Pappas Michail
Published: May 2021

Socialization is a process during which we learn and adopt knowledge about rules and norms of our culture and through which we are enabled to collaborate with other social subjects. Individuals are socialized into an organization or a group by the method that is in its foundation the same as the method of socialization into society. As an individual becomes employed by an organization he becomes a part of that same organization, helps in the organization achieve its objectives, but also becomes a part of the community consisting of all the employees and executives, and this is where the theory of organizational socialization derives from. Organizational socialization is a responsibility of the management. Managers have the assignment to present new members of their organization with optimal information about rules and regulations, so they are able to fit into their organization in a most efficient way. This means that the manager is the main authoritative and creative body in creation and implementation of a successful organizational socialization tactics, because successful socialization of new employees means rise in productivity, and that rise in productivity should be the end objective of every successful manager.

Covid 19 is a disease that has spread all over the world. It caused upheavals in all societies and segments of society. This also relates to the Serbian society and its educational system. Education, as an important part of society, experienced a concussion. Serbia's cumbersome education system, many ongoing reforms, dissatisfaction of educators, many unresolved issues were now additionally burdened by the crown and everything it brings with it. How much of the education system, to which the primary school belongs, has successfully responded to these changes? The inflexibility and inelasticity of the education system was a major obstacle in response to such a large demand made by the Coronavirus. The transition from school to online teaching was stressful for all participants: pupils, parents and teachers. In addition to changes in the way of working, primary schools in Serbia have faced problems with the lack of information technology needed for distance learning, teaching staff who are not educated for this type of teaching, but also the quality of such teaching. All this raised the question of the quality of knowledge that pupils acquired during distance learning. The paper will discuss the management of the primary school at the time of the Covid 19, the problems encountered and how they were solved.

Since December 2019, SARS-CoV-2 infections have altered many aspects of our societies. Citizens were faced with circumstances to which even experts and scientists did not yet know the answers and were applying the scientific method to make daily steps of progress towards better understanding the threat and how to contain it. Within a year, several vaccines were produced to protect individuals from the virus, thereby resolving the most important medical problem. However, not just medical issues call for the application of the scientific method. The management of epidemics also can, and in fact should, benefit significantly from a science-based approach. The novel complexity of the situation left us torn between permissive and authoritarian approaches of containment, and it is still subject to debate what works best and why. In our contribution, we model the emerging complexity of the epidemics and propose a scientific-based data driven approach that aims to aid the decision makers in their focus on the most relevant issues and thus helping them to make informed and consistent decisions. The resulting monitoring and control system, termed COVID-19 vigilance, helps with risk assessment and communication during regional COVID-19 outbreaks. The system is based on the Cynefin decision complexity framework and the universal process model, and it uses several mathematical models that describe epidemic spreading. Different future scenarios are used to predict the impact of realistic, optimistic, and pessimistic outcomes, in turn allowing for a more efficient communication of involved risk.

The Slovenian economy did not sufficiently recognize and use the internal audit function. This is largely true for that part of the economy where internal audit is not legally defined as a key function. However, in the world, it is the internal auditor who also helps the organization in the field of making sense of values, the importance of competencies and introducing changes. These are the elements that affect the size and distance of risks and opportunities. One of the key success factors is employees. The organization needs to have the right people in the right place. Be it middle, senior management or professionals such as internal auditors. Among other things, the pandemic showed how the Human resource function influences the long-term success of the organization through the right and timely selection of personnel. Nevertheless, in all my many years of practice, I have never managed to get the management and then the supervisory board to accept the proposal that the human resources function and its efficiency and effectiveness be included in the annual internal audit plan.

The aging workforce challenges companies to keep their aging employees employable in the workforce. This paper gives an indication as to which employees are more likely to be interested in further learning and employability. Specifically, the aim of this study was to investigate the role of chronological age and achievement goal orientations for informal and formal learning and employability. It was found that informal learning has a significant positive relation with several dimensions of employability. Furthermore, mastery-approach goal orientation also shows a significant positive relation with informal learning and employability. In addition, age had no significant relation with the achievement goal orientations. The paper stresses the need to consider characteristics other than chronological age, such as goal orientations, when considering employees’ learning behavior and employability.
Vrednote kot podlaga za pravne norme in delovanje organizacij
Authors: Igličar Albin
Published: May 2021

Values as relatively enduring ideas about the good and fair treatment of people in society are the most general part of the normative world. Therefore, they are also the forerunners of legal norms that institutionalize and operationalize values or ideas about the desired social functioning of people. By defining rights and duties in legal norms, social relations also become legal relationships. The result of conscious and rational connections of people is formal organizations as institutional frameworks that encourage and monitor the activities of their members. It is therefore possible to imagine a sequence: values --- norms --- organization --- action.

t Many industrial incidents, which have taken place since the seventies of the last century onwards, have raised many questions and conclusions. These disasters have shown that it is a human, a key risk factor for the survival of all living on our planet. The very approach to the prevention and recovery system proved to be frivolous, careless, and full of holes, and as a result, we got the devastating consequences. After these incidents, the environmental awareness and acceptance of the domino effect, which they carried with them, arose. When an industrial accident occurs, it causes people's death and affects the economy, social stability, and endangering the environment and biodiversity. Therefore, in the prevention process and various laws and directives, with the development of technology, there is also the development of computer programs to anticipate possible hazards and speed up the repair of the problem when this happens.

Estrategias de representación política de las religiones africanas en el parlamento gaucho
Authors: Leistner Rodrigo Marques , Mateus Sílvia Gonçalves
Published: May 2021

El trabajo investiga los discursos parlamentarios de dos agentes políticos de Rio Grande do Sul - Moab Caldas (Asamblea Legislativa del Estado de Rio Grande do Sul, de 1959 a 1966) y Vera Soares (Ayuntamiento de Porto Alegre, en 2017), ambos miembros de religiones de matriz africana. Lo que se busca es identificar en sus discursos las estrategias de representación política y la lógica de la legitimación social en defensa de este segmento con la sociedad circundante. No sólo porque son casos raros de la presencia de representantes de estas religiones en la esfera política, sino también porque cada uno se inserta en un período histórico específico (en los períodos comúnmente conocidos como blanqueamiento y reafricanización de las religiones afrobrasileñas), tal corte proporciona un análisis comparativo sobre las diferentes modalidades de presencia de estas religiosidades en la esfera pública y en el campo político brasileño.

Los textos reunidos en este dossier remiten incesablemente a la pregunta que pone en relación los términos de agencia y normatividad. Lo que aquí se trata es de presentar cómo al romper con los juicios normativos se profundiza en la capacidad de agencia (agenciatividad). Estos manuscritos son producto de una discusión previa que se desarrolló en el marco de las Jornadas sobre Alternativas Religiosas en América Latina. El grupo de trabajo desde donde partieron muchas de las discusiones aquí figuradas se conformó teniendo como principio un equilibrio que representara autores y autoras de distintas disciplinas y academias que componen la Asociación de Cientistas Sociales de la Religión del Mercosur y que trabajan desde Argentina, Brasil, Chile, Uruguay; así como aquellas otras academias en Francia e Italia con las que se entablaron lazos de diálogo e intercambio científico. Nueve artículos de los doce iniciales conforman un variado corpus cuya temática tiene como eje pensar el género, la construcción de las agencias, la disposición de las normatividades y la condición de subalternidades, no con el afán de volver sobre viejos dilemas sino de problematizar desde otras ópticas. Los/as lectores/as encontrar trabajos más consolidados y otros más incipientes. Esta diversidad da cuenta de los distintos recorridos de cada investigador/a, pero también de la dificultad de pensar la normatividad bajos análisis menos cómodos y menos habituales.
Cuando el secreto es "ese" secreto
Authors: Leal Lucas Edgardo
Published: May 2021

Son muchos los cambios significativos que se han dado en las últimas décadas en relación a la sociabilidad y visibilidad del colectivo LGTBI+ en nuestro país con leyes que lo colocan en la vanguardia legislativa en el reconocimiento de las demandas en torno a los derechos sexuales y la ciudadanía plena de las identidades autopercibidas como no heterosexuales. Este camino de reconocimiento estatal no ha sido acompañado por la jerarquía de la Iglesia católica que continúa, en sus discursos y prácticas, estigmatizando, patologizando y moralizando a las sexualidades autopercibidas como no heterosexuales. Sin embargo, más allá de estos discursos y prácticas opuestos al reconocimiento de sexualidades autopercibidas como no heterosexuales, muchos sujetos autoidentificados como gays viven su dimensión creyente en el contexto institucionalizado de la Iglesia católica. En este trabajo exploro, en fragmentos de una entrevista, las estrategias de visibilidad-invisibilidad y la pertenencia institucional a la Iglesia católica.
Procrear en la norma
Authors: Fassatoui Omar
Published: May 2021

Las parejas religiosas -al igual que cualquier otra pareja- confrontan con la infertilidad buscando soluciones dentro las tres religiones monoteístas las que indiscutiblemente incentivan la procreación. Con este propósito, las parejas recurren a las técnicas de reproducción médicamente asistida (nuevas técnicas reproductivas). Al indagar sobre el deseo de concebir un niño y al comparar este deseo con parejas menos religiosas, podemos observar un encuadre original mediante el cual estas parejas habitan la norma. Ciertamente estas parejas desean concebir en concordancia con las reglas religiosas. Bajo este fundamento las parejas pueden excluir algunas técnicas existentes y efectivas que serían incompatibles con las normativas religiosas a las cuales adscriben. Explorando algunos casos dentro del judaísmo y el islam en el Mediterráneo, en este trabajo se busca analizar cómo las parejas habitan la norma convencional dentro del sistema de salud en general y, especialmente, del nivel estatal (ya sea en el caso de la religión de Estado o el de la religión oficial del Estado). También observaremos a través de ejemplos concretos en contextos judíos y musulmanes cómo las normas religiosas pueden reducir o expandir el rango de técnicas que las parejas infértiles pueden emplear. Analizaremos cómo las parejas de creyentes habitan la norma -presentando una posición original cuando sus prácticas se acomodan a las normas convencionales-, así como también el rol que ejercen los procesos de globalización e internet en esta misma dirección. Por último, veremos cómo se construyen la religiosidad aceptada y la medicina avanzada.
Renovación carismática católica en mar del plata
Authors: Sánchez Gabriela
Published: May 2021

La Renovación Carismática Católica es uno de los movimientos de la nueva sensibilidad católica pos-conciliar. Se caracteriza por el protagonismo que desempeñan los laicos en su estructura y su apertura al ecumenismo. Nos proponemos responder un problema central que es conocer cuáles son las prácticas distintivas de la Renovación Carismática Católica (en adelante RCC). A través del conocimiento de estas prácticas se intentará comprender de qué forma se producen las transformaciones de la subjetividad en los individuos que participan en la RCC. En este trabajo presentaremos las instituciones y prácticas dentro de la RCC. Analizaremos desde lo institucional la estructura organizativa de la RCC, remarcando la importancia que le otorgamos al grupo de oración. Luego nos centraremos sobre ritos carismáticos, dividido en grupos de oración, seminario de vida y misas carismáticas. El objetivo es realizar un análisis de las prácticas religiosas, pero incorporando la dimensión de los institucional. Sostengo que no es posible comprender completamente las propiedades de las prácticas sin vincularlas con la institución que las alberga, y sobre esto intentar comprender el modo en que viven las creencias y disposiciones, analizando de manera conjunta las prácticas y su base institucional.
La umbanda en la región metropolitana de Belo Horizonte
Authors: Maia Anderson Marinho , Ferreira Amauri Carlos
Published: May 2021

El objetivo de este artículo fue investigar las diferencias y similitudes de los cultos de umbanda a través de entrevistas en cuatro (4) terreiros (ubicados en Belo Horizonte y Contagem), además de la identidad de cada uno. Asociar Umbanda con el mito de muiraquitã nos permite comprender la unidad en la diversidad. La analogía con el mito representa los diferentes templos de Umbanda estudiados y busca informaciones recurrentes en la esfera micro/privada capaz de reflejar las prácticas umbandistas en la esfera macro/general, además de la importancia de respetar al otro y rescatar la memoria colectiva de diferentes narrativas. En el proceso de sincretismo de Umbanda, considerada una religión genuinamente brasileña, se notó que hubo pérdidas, adaptaciones y ganancias que generaron sus especificidades: la historia única de cada segmento en la formación de la historia de Umbanda.
"El fidencismo es superstición popular, mito, hipnosis, semireligión"
Authors: Gervasi Francesco
Published: May 2021

En este artículo se presentan los resultados de una investigación que se enfoca en las formas de intolerancia en contra de la devoción hacia el Niño Fidencio. Su objetivo general es analizar el discurso producido sobre esta devoción en sitios de noticias, nacionales y del estado de Coahuila, para detectar las notas en las cuales recibe un tratamiento desacreditador. El propósito final del estudio es reconstruir la imagen deteriorada de la devoción que se difunde en esas notas. Con base en la revisión realizada, he encontrado que, en las notas de los sitios de noticias del estado de Coahuila, el tratamiento de la devoción es desacreditador en el 32.87% de los casos, mientras que en los sitios nacionales, en el 25%. La imagen de la devoción difundida en esas notas con tratamiento negativo (28) es la de una forma de religiosidad engañosa, peligrosa, irracional y para devotos fanáticos, ignorantes y sin voluntad propia.
The Impact of Patient’s Fear of COVID-19 Infection on Neurology Service in University Hospital Center Sestre Milosrdnice During COVID-19 Epidemic Outbreak
Authors: Lovrenčić-Huzjan Arijana , Roje-Bedeković Marina , Collaboration Group Neurology
Published: May 2021

Increasing evidence suggests that patients with medical emergencies are avoiding the emergency department because of fear of coronavirus disease 2019 (COVID-19) infection, leading to increased morbidity and mortality due to other diseases. In order to analyse the impact of patient’s fear of COVID-19 on the admittance rate of stroke patients and severity of neurological diseases, we compared the stroke admittance rate, numbers of thrombectomies and thrombolysis and hospitalization refusal rate during the time period from March 1st until June 30th 2020 in temporal relationship with the rising numbers of COVID-19 cases in Croatia. We assessed the patients’ neurologic disease severity measured by ventilation time and mortality rate in the same time period. We compared the data with the data obtained from the same time period in 2019. We observed dramatically decreased presentation in Neurologic Emergency Department due to stroke and neurologic disease in 2020 compared to 2019, increased refused hospitalization rate and similar stroke treatment rate despite bigger catchment area. Greater neurologic disease severity with almost 40% increased ventilation time and double mortality rate during the same time was observed. During the outbreak of COVID-19 epidemic, fear of infection had significant impact on neurologic service leading to decreased presentation to NED, resulting in increased stroke or neurologic disease-related morbidity and mortality.

Hidrolisis Garam merupakan salah satu konsep yang relatif dianggap sulit dan membingungkan bagi siswa. Salah satu sebabnya adalah karena konsep ini, berkaitan dengan konsep asam-basa, sebagai konsep prasyarat yang harus dikuasai siswa sebelum mempelajari Hidrolisis Garam. Materi Hidrolisis Garam yang dipelajari siswa kelas XI IPA di SMA dimaksud, mencakup konsep asam basa, persamaan reaksi, konsep mol, serta rumus-rumus perhitungan pH. Penelitian ini bertujuan untuk mendeskripsikan kemampuan pemahaman konseptual Hidrolisis Garam siswa kelas XI SMA di Gorontalo. Deskripsi penelitian ini dilakukan secara kualitatif, dari hasil analisis data 81 siswa sebagai subjek penelitian. Subjek ditentukan secara random dari beberapa SMA di Gorontalo. Data dikumpulkan mengunakan tes pilihan ganda Hidrolisis Garam, yang dikerjakan subjek secara tertulis. Hasil penelitian menunjukkan bahwa kemampuan siswa dalam menentukan sifat asam, basa, dan netral suatu senyawa, mencapai rata-rata 47%. Hasil ini makin menurun, di mana hanya ditunjukkan rata-rata 42% siswa yang dapat menentukan sifat garam yang mengalami hidrolisis. Demikian pula, hanya rata-rata 34% siswa yang dapat reaksi hidrolisis dari berbagai jenis garam ditinjau dari jenis reaksi dan dari hidrolisis (sebagian, total dan tidak terhidrolisis). Dan, hanya rata-rata 38% siswa yang dapat menentukan pH larutan garam yang terhidrolisis. Temuan ini mengindikasikan bahwa sebagian besar siswa yang cenderung mengalami miskonsepsi pada materi hidrolisis garam.
How accurate are WorldPop-Global-Unconstrained gridded population data at the cell-level?: A simulation analysis in urban Namibia
Authors: Thomson Dana R. , Leasure Douglas R. , Bird Tomas , Tzavidis Nikos , Tatem Andrew J.
Published: May 2021

Disaggregated population counts are needed to calculate health, economic, and development indicators in Low- and Middle-Income Countries (LMICs), especially in settings of rapid urbanisation. Censuses are often outdated and inaccurate in LMIC settings, and rarely disaggregated at fine geographic scale. Modelled gridded population datasets derived from census data have become widely used by development researchers and practitioners. These datasets are evaluated for accuracy at the spatial scale of the input data which is often much courser (e.g. administrative units) than the neighbourhood or cell-level scale of many applications. We simulate a realistic "true" 2016 population in Khomas, Namibia, a majority urban region, and introduce realistic levels of outdatedness (over 15 years) and inaccuracy in slum, non-slum, and rural areas. We aggregate these simulated realistic populations by census and administrative boundaries (to mimic census data), and generate 32 gridded population datasets that are typical of a LMIC setting using WorldPop-Global-Unconstrained gridded population approach. We evaluate the cell-level accuracy of these simulated datasets using the original "true" population as a reference. In our simulation, we found large cell-level errors, particularly in slum cells, driven by the use of average population densities in large areal units to determine cell-level population densities. Age, accuracy, and aggregation of the input data also played a role in these errors. We suggest incorporating finer-scale training data into gridded population models generally, and WorldPop-Global-Unconstrained in particular (e.g., from routine household surveys or slum community population counts), and use of new building footprint datasets as a covariate to improve cell-level accuracy. It is important to measure accuracy of gridded population datasets at spatial scales more consistent with how the data are being applied, especially if they are to be used for monitoring key development indicators at neighbourhood scales with relevance to small dense deprived areas within larger administrative units.
Gene Editing and Gene Therapy: Entering Uncharted Territory in Veterinary Oncology
Authors: Wierson Wesley , Abel Alex , Siegler Elizabeth , Ekker Stephen , Johannes Chad , Kenderian Saad , Mochel Jonathan
Published: May 2021

With rapid advances in gene editing and gene therapy technologies, the development of genetic, cell, or protein-based cures to disease are no longer the realm of science fiction but that of today’s practice. The impact of these technologies are rapidly bringing them to the veterinary market as both enhanced therapeutics and towards modeling their outcomes for translational application. Simply put, gene editing enables scientists to modify an organism’s DNA a priori through the use of site-specific DNA targeting tools like clustered regularly interspaced short palindromic repeats and CRISPR-associated protein 9 (CRISPR/Cas9). Gene therapy is a broader definition that encompasses the addition of exogenous genetic materials into specific cells to correct a genetic defect. More precisely, the U.S Food and Drug Administration (FDA) defines gene therapy as “a technique that modifies a person’s genes to treat or cure disease” by either (i) replacing a disease-causing gene with a healthy copy of the gene; (ii) inactivating a disease-causing gene that was not functioning properly; or (iii) introducing a new or modified gene into the body to help treat a disease. In some instances, this can be accomplished through direct transfer of DNA or RNA into target cells of interest or more broadly through gene editing. While gene therapy is possible through the simple addition of genetic information into cells of interest, gene editing allows the genome to be reprogrammed intentionally through the deletion of diseased alleles, reconstitution of wild type sequence, or targeted integration of exogenous DNA to impart new function. Cells can be removed from the body, altered, and reinfused, or edited in vivo. Indeed, manufacturing and production efficiencies in gene editing and gene therapy in the 21st century has brought the therapeutic potential of in vitro and in vivo reprogrammed cells, to the front lines of therapeutic intervention (Brooks et al., 2016). For example, CAR-T cell therapy is revolutionizing hematologic cancer care in humans and is being translated to canines by us and others, and gene therapy trials are ongoing for mitral valve disease in dogs.
One-electron Energy Spectra of Heavy Highly Charged Quasimolecules
Authors: Kotov Artem A. , Glazov Dmitry A. , Shabaev Vladimir , Plunien Günter
Published: May 2021

The generalized dual-kinetic-balance approach for axially symmetric systems is employed to solve the two-center Dirac problem. The spectra of one-electron homonuclear quasimolecules are calculated and compared with the previous calculations. The analysis of the monopole approximation with two different choices of the origin is performed. Special attention is paid to the lead and xenon dimers, Pb82+–Pb82+–e− and Xe54+–Xe54+–e−, where the energies of the ground and several excited σ-states are presented in the wide range of internuclear distances. The developed method provides the quasicomplete finite basis set and allows for construction of the perturbation theory, including within the bound-state QED.
Full-Field Measurements in the Edge Crush Test of a Corrugated Board – Analytical and Numerical Predictive Models
Authors: Garbowski Tomasz , Grabski Jakub Krzysztof , Marek Aleksander
Published: May 2021

The article focuses on derivation of simplified predictive models for identification of overall compressive stiffness and strength of corrugated cardboards. As a representative example an unsymmetrical 5-ply sample (with E and B flute) was used in this study. In order to exclude unreliable displacement measurement in the standard edge crush test, the virtual strain gauges are used. Video extensometry is employed here to collect measurements from the outer surfaces of the sample on both sides. Additional data allows for obtaining real force-displacement curves, which are used in the validation procedure. To emulate the experimental results, beside simple analytical model, also a 3D numerical model fully reflecting the geometry of the corrugated board, based on finite elements method was also built. In both cases a good agreement between the experimental results and the analytical and numerical calculations was observed. This proves that the proposed analytical model can be successfully used to determine the overall stiffness and compressive strength of the corrugated board, provided that the geometry and properties of all the layers of the board are known. The simple model presented in this work enables quick and reliable design and prototyping of new assemblies without the need to manufacture them.

Published: May 2021

Missing observations constitute one of the most important issues in data analysis in applied research studies. The magnitude and their structure impact parameters estimation in the modeling with important consequences for decision-making. This study aims to evaluate the efficiency of imputation methods combined with the backpropagation algorithm in a nonlinear regression context. The evaluation is conducted through a simulation study including sample sizes (50, 100, 200, 300 and 400) with different missing data rates (10, 20, 30 40 and 50%) and three missingness mechanisms (MCAR, MAR and MNAR). Four imputation methods (Last Observation Carried Forward, Random Forest, Amelia and MICE) were used to impute datasets before making prediction with backpropagation. 3-MLP model was used by varying the activation functions (Logistic-Linear, Logistic-Exponential, TanH-Linear and TanH-Exponentiel), the number of nodes in the hidden layer (3 - 15) and the learning rate (20 - 70%). Analysis of the performance criteria (R2, r and RMSE) of the network revealed good performances when it is trained with TanH-Linear functions, 11 nodes in the hidden layer and a learning rate of 50%. MICE and Random Forest were the most appropriate for data imputation. These methods can support up to 50% of missing rate with an optimal sample size of 200.

Objectives: To determine the prevalence of controlled systemic hypertension and its associated risk factors among the hypertensive patients who attended the clinic at Mbeya Zonal Referral Hospital in Tanzania. Methods: A descriptive cross-sectional quantitative study was used determine the prevalence of co to 252 hypertensive patients were recruited during clinic visit from September to November 2020 and participant was randomly selected interviews using structured self-administered questionnaires. Data was analyzed using chi square test to find the risk factors associated with controlled hypertension. Results: Among 252 participants, 94(39.7%) individuals with controlled hypertension giving the prevalence of controlled hypertension. The proportion of females with controlled hypertension was slightly higher than male (49 females to 45 males). The prevalence of uncontrolled hypertension was 152(60.3%) participants. The prevalence of controlled hypertension was higher among patients who have regular clinic visit (p< .05) and have daily adherence to their anti-hypertensive medication. A similar trend was observed among participants without financial challenges to attend clinic, short duration of illness, higher level of education and there was no association between age, sex, marital status, smoking, alcohol consumption, having health insurance and having chronic illness. Conclusion: Prevalence of controlled hypertension is higher among patients who have regular clinic visit and have daily adherence to their anti-hypertensive medication. Also, it is higher among participants without financial challenges to attend clinic so they can have regular clinic visit and checkup. Reinforcement on regular drug intake and clinic visit, good nutrition and reduced salt intake and modifying lifestyles of patient with hypertension is important.

The Savings and Credit Cooperative Societies (Saccos) in Kenya have made a tremendous contribution to national development which is responsible for about 45% of Gross Domestic Product and 31% of national savings and deposits. Deposit Taking Saccos (DTSs) have enabled cooperative societies to diversify their products and services in a highly competitive market. Those who patronize the services of DTSs have options of accessing similar services from other service providers like commercial banks and non-banking financial institutions that may enjoy economies of scale due to their size. However, some of the DTSs may be small in size which makes it difficult for them to leverage on size for wider coverage of their catchment market. Guided by Human Capital Theory (HCT) and the Resource-Based View (RBV) as the theoretical framework. The purpose of this study was to examine firm size as an important influencing factor on organization performance. The study adopted a descriptive design. The study was a census of the 42 DTSs operating in Nairobi County, Kenya. The target respondents were Chief Executive Officers and Human Resource Managers in the DTSs. Data was collected from 39 respondents using a questionnaire that was tested for reliability and validity. Data was analyzed using descriptive and statistical techniques. Cross-tabulation of the number of employees and organizational performance was done. Chi-square tests were also conducted. The findings of the study indicate that the DTSs with the highest number of employees performed higher than those with fewer employees. These findings suggest that organizations should pay more attention to firm size and leverage on the optimum size for competitiveness in the market.
An Improved Multicomponent Diffusion Model for Compositional Simulation of Fractured Unconventional Reservoirs

Most simulators currently use the advection/diffusion model (ADM), where the total flux comprises Darcian advection and Fickian diffusion. However, significant errors can arise, especially for modeling diffusion processes in fractured unconventional reservoirs, if diffusion is modeled by the conventional Fick’s law using molar concentration. Hence, we propose an improved multicomponent diffusion model for fractured reservoirs to better quantify the multiphase multicomponent transport across the fracture/matrix interface.

We first give a modified formulation of the Maxwell-Stefan (MS) equation to model the multicomponent diffusion driven by the chemical potential gradients. A physics-based modification is proposed for the ADM in fractured reservoirs, where fracture, matrix, and their interface are represented by three different yet interconnected flow domains to honor the flux continuity at the fracture/matrix interface. The added interface using a more representative fluid saturation and composition of the interface can hence better capture the transient mass fluxes between fracture and matrix. The proposed approach is also implemented in an in-house compositional simulator. The multicomponent diffusion model is validated with both intraphase and interphase diffusion experiments. Then, the improved model for fracture/matrix interaction is compared with a fine-grid model. The proposed multiple interacting continua (MINC) model with three continua (MINC3) can better match the fine-grid model’s result than the double-porosity (DP) model, which only obtains a fair match at an early time.

Then, we simulate a gas huff ‘n’ puff (HnP) well in the Permian Basin to investigate the effect of diffusion within the fractured tight oil reservoir. The simulation reveals that diffusion has a minor effect on the performance of depletion when oil is the dominant phase. For gas HnP, the simulation neglecting diffusion will underestimate the oil recovery factor (RF) but overestimate the gas rate. The DP approach tends to overestimate the RF of heavy components but leads to a similar cumulative oil RF compared with MINC3. With the diffusion included in the simulation, gas HnP performance becomes more sensitive to the soaking time than the model without diffusion. Although increasing the soaking time will lead to a higher RF after considering diffusion, the incremental oil is not sufficiently large to justify a prolonged soaking time.

Background: Autoimmune thyroid diseases (AITD) are among the most common autoimmune diseases in the world. They are usually accompanied by the presence of anti-thyroid antibodies as the early predictive marker. Genetic determinants of the susceptibility to develop thyroid antibodies are still poorly understood. This study aimed to investigate the relation between thyroid peroxidase (TPO) gene variants (53 SNPs) and positive TPOAb and also to evaluate the effect of some environmental factors on changes from negative to positive TPOAb (Seroconversion). Methods: Participants from the Tehran Thyroid Study (TTS) in phases 1 and 2 (N=5317, ≥ 20 years) were evaluated for the positive TPOAb and its relationship with 53 SNPs from TPO gene (a cross-sectional approach). At the second stage of the study (a longitudinal approach), negative TPOAb participants (control group, N= 4815) were followed up for about 5.5 (5.54±1.62) years until they have had positive results for TPOAb (“TPOAb seroconversion”). The association between TPO gene polymorphisms and TPOAb seroconversion was evaluated using logistic regression analysis and SKAT (sequence kernel association test) package. Results: In cross-sectional analyses, 17 SNPs were associated with TPOAb positivity (521 positive TPOAb participants) after the adjustment for age, sex, body mass index (BMI), smoking, the number of parity and oral contraceptive consumption (P <0.05). In longitudinal analyses, there was an association between TPOAb seroconversion and four SNPs before, and three SNPs after adjustment (P <0.05). Conclusions: TPOAb seroconversion could be affected by some thyroid peroxidase gene variants.

This research aims to determine the mediating role of e-health literacy levels on the relationship between awareness of coronavirus precautions for Covid-19 and dispositional hope during the Covid-19 era. The current research is based on sequential explanatory design. The quantitative data in this research were collected online Google form, and the qualitative data were collected using the online interview technique. Participants from whom qualitative data were obtained were determined using the analog sampling method, one of the criterion sampling method. Participants from whom the quantitative data of the study were obtained were determined using the snowball sampling method, one of the purposeful sampling methods. As a result of testing the structural equation model, it has been determined that e-health literacy has a full mediating role between awareness of koronavirus and dispositional hope. In addition, in the study, it was observed that people who had Covid-19 increased their awareness of Covid-19 before and after the disease. It has been determined that people pay more attention to the precautions that should be taken for the transmission of the disease, especially after the disease. As a result, it can be said that the necessity of raising the awareness of individuals and giving priority to increasing the level of e-health literacy has emerged.
