Reconsidering a multivalent concept: An integrated affordance framework to approach technology and social media use
Authors: Frey Tobias
Published: July 2023

The affordance concept has been widely used in communication studies to theorize and examine social media use beyond specific features and practices. However, its implementation is characterized by an inconsistent use of terms and a neglect of the concept’s relationality. The present article demonstrates and addresses these shortcomings. First, it briefly reviews the affordance perspective’s origins and its further development in communication literature. Second, it outlines the perspective’s diverse but inconsistent application in social media research. Third, it introduces an integrated framework that contributes to a better understanding of affordances and supports a more precise use of the underlying concepts and terms in social media research. The framework a) emphasizes the relational nature of affordances as opportunities for action that occur in various technological and social contexts and are contingent on designed and cognitive mechanisms, b) it highlights the abstract nature of individual, relational, and collective affordances that are distinct from outcomes such as practices and structures, and c) it encompasses effects and dynamics that impact both technology and actors. Drawing on the framework, the article concludes with conceptional, empirical and terminological implications for future research approaching technology and social media use from an affordance perspective.
Techniques and Methods for Measuring the Texture of Processed and Fresh Agro-Food Products – A Review
Authors: Lupu Mariana , Nedeff Valentin , Panainte Mirela , Rusu Dragoş-Ioan
Published: July 2023

The measurement of texture is a widely used method in postharvest and food research. The majority of the textural characteristics of fresh foods, such as vegetables and fruit, are frequently employed as maturity indicators in order to meet long-term storage, transportation and customer fulfillment requirements. Understanding the textural features is also crucial for controlling processing processes like drying, heating, and frying on processed foods. The sensory qualities of the texture have been evaluated using a variety of methods. The methods for measuring texture that are most frequently used are objective tests using a variety of tools. The set of physical qualities referred to as a food’s textural properties includes those that arise from the structural elements of the food, are primarily perceived through touch, are associated with the distortion, disappearance, and the response of food under the action of a force and are evaluated objectively by functions of quantity, distance or time. Due to their well-balanced supply of nutrients, including sugars, organic acids, vitamins, pro-vitamins, and minerals, as well as non-nutritional, advantageous components like fiber and secondary metabolites, fresh fruit and vegetables are vital dietary items for human nutrition. Production processes need to be managed sustainably while producing high-quality products. At harvest, the maturity stage is typically an important factor not only affecting the product quality at harvest but also the susceptibility of the product postharvest. In postharvest, the main task is maintaining the good quality of perishable products for as long as possible to avoid food waste and economic losses. Consequently, knowledge of factors related to produce quality in the pre-harvest, harvest, and post-harvest stages is relevant for the producer, harvest manager, storage manager, packaging facility personnel, local markets, global distributors, wholesalers, and consumers. The word quality is consistently used throughout the production-to-consumption chain, but its definition changes depending on where in the chain you are. Yet, in each of these stages, quality refers to the product’s level of excellence and lack of defects (absence of defects and blemishes, cultivar-typical ripeness, freshness, a non-harmful amount of residues considering pesticides and other chemicals, and cleanliness). Texture represents one of the four principal factors defining food or fruit quality, together with appearance, flavor, and nutritional properties, and plays a key role in consumer acceptability and recognition of agro-foods.

Published: July 2023

In this paper, the expression of the electrostatic interaction force between two charged particles is derived in the framework of Stochastic Electrodynamics. The fundamental assumption is that the electrically charged particle can be modeled as a two-dimensional oscillator that scatters the classical zero point field background radiation. The correct expression of the electrostatic force is obtained if the natural pulsation of the oscillator is equal to the Zitterbewegung angular velocity.
Multimodality Imaging-Based Therapeutic Decision in Ischemic Cardiomyopathy and Ventricular Tachycardia – a Case Report
Authors: Sascău Radu Andy , Clement Alexandra , Stătescu Cristian
Published: July 2023

Introduction

In patients with ischemic heart disease and coronary chronic total occlusion, it is extremely important to assess the presence of myocardial viability via different cardiac imaging techniques in order to predict a potential functional recovery following revascularization. Multimodality cardiac imaging techniques estimate the risk of sudden cardiac death and personalize patient selection for primary prevention implantable cardioverterdefibrillator therapy.

Case presentation

A 61-year-old patient with a history of an extensive anterior myocardial infarction with conservative management (8 years before the current presentation, when the coronary angiography revealed two-vessel chronic total occlusion) presented to our outpatient service for fast-paced palpitations at home and fatigue. At the time of the index hospitalization, the patient refused coronary artery bypass grafting. During this period, he did not undergo any cardiovascular evaluation, but he did follow the pharmacological recommendations from the initial hospital discharge. Given the detection of multiple premature ventricular contractions and numerous episodes of nonsustained ventricular tachycardia during this medical visit, a multimodal imaging evaluation was conducted, which further guided the implementation of a personalized therapy.

Conclusions

In patients with ischemic heart failure and coronary chronic total occlusion, presenting with ventricular tachycardia, the therapeutic decision should be based on the results of a multi-modality cardiac imaging evaluation.

Published: July 2023

Introduction

Early vaccination of cattle with an inactivated commercial bacterial vaccine against bovine respiratory disease has been reported to increase antibody production and can alleviate the disease. However, its dosage has been little investigated in young Holstein calves. This study addresses the need to establish guide values for vaccine dosage in these animals.

Material and Methods

Healthy calves received an inactivated vaccine for Histophilus somni, Pasteurella multocida and Mannheimia haemolytica intramuscularly at the ages of 1 and 4 weeks. Administered vaccine doses were 1.0 mL for the primary and booster vaccinations (1.0 + 1.0 group), 0.5 mL for the primary and 1.0 mL for the booster vaccination (0.5 + 1.0 group), or 0.5 mL for both vaccinations (0.5 + 0.5 group).

Results

Differences in the vaccine responses between the 1.0 + 1.0 group and 0.5 + 1.0 group were minor. However, the number of calves with a positive vaccine response to H. somni in the 0.5 + 0.5 group was less than half of that in the 1.0 + 1.0 and 0.5 + 1.0 groups. In logistic regression analysis, although the booster vaccination dose was positively correlated with seropositivity for H. somni, the primary vaccination dose was not correlated with vaccine response. The number of calves with positive vaccine responses to M. haemolytica was low even after booster vaccination regardless of the dose.

Conclusion

The dose of 0.5 mL can be used for primary vaccinations in newborn Holstein calves, but 1.0 mL may be required for booster vaccinations.

Published: July 2023

Introduction.
This study focuses on the sensory information delivered by the visual system, particularly in the peripheral visual field (PVF). Visual abilities, especially the ability to detect peripheral information, have been identified as important factors for successful performance in team sports. Athletes often need to divide their visual focus between central and peripheral fields to achieve optimal performance. However, research on visual perception in athletes with varying levels of experience is still limited. The aim of the study was to compare peripheral perception of basketball players at different level of experience.

Material and Methods.
In study 165 basketball players took part at different level of experience. An analysis compare abilities general visual functions (i.e. field of vision) and reaction time to visual stimuli. Peripheral perception was examined using the peripheral test included in Vienna Test System (VTS, Schuhfried, Austria). During the test variables were recorded: total field of vision, viewing angle of the left and right eye., tracking deviation, number of correct reactions, the number of omitted responses and median reaction time – left and right stimuli.

Results.
The results indicate that the E and U19 groups had significantly shorter response time to stimuli appearing in the peripheral field of vision compared to U15 group. Two more experienced groups had bigger field of vision than U15. No statistically significant differences were observed between E and U19 group.

Conclusions.
The study highlights the importance of perceptual skills, particularly in anticipation and decision-making processes, for basketball players due to the high number of stimuli involved in the sport. Understanding these differences can inform training strategies and help identify areas that may require additional attention for optimal performance. The accumulation of high volume of sport specific exercises may facilitate the development of perceptual expertise in basketball players.
Sport, Physical Activity and (Harmful) Alcohol Drinking in University Students During the First Year After COVID-19 Pandemic: Gender-Stratified Cross-Sectional Study
Authors: Drenjak Jasna Lulić , Užičanin Edin , Zenić Nataša
Published: July 2023

Introduction.
COVID-19 pandemic increased consumption of alcohol (including harmful drinking – HD), and decreased physical activity levels (PAL) globally, but there is an evident lack of studies examining the problem in the post-pandemic period. This study aimed to evaluate gender-specific associations between sport participation and PAL (independent variables), and HD (dependent variable) among college/university students during the first post-pandemic year of the COVID-19 pandemic.

Material and Methods.
The participants were college/university students, aged 18 to 21 years (n = 788; 409 females) from Croatia and Bosnia and Herzegovina. They were tested on socio-demographic factors, HD (using the AUDIT scale), sport participation and PAL (using the IPAQ questionnaire). Analysis of variance, Chi square test, and t-test for independent samples were used to evaluate differences, while logistic regression with dichotomized criterion (HD vs. non-harmful drinking – NHD) was calculated to establish associations between independent and dependent variables.

Results.
T-test indicated significant differences between HD and NHD in PAL (t-test = 2.16, p = 0.02), but only in males. Also, logistic regression indicated a significant correlation between PAL and HD in males (OR: 1.41, 95%CI: 1.11-1.76), while no association was evidenced: (i) between sport participation and HD (in both males and females), and (ii) between PAL and HD (in females).

Conclusions.
Results indicated that an overall increase in PAL could be helpful in decreasing HD among college/university students; however, to evaluate it more specifically, prospective analyses are needed.

The article addresses how the headman and the legislative members of the village in Aceh overcome issues in managing the village income and expenditure budget. Using a qualitative method, the article inductively analyzes the styles of the headman and the village legislature in dealing with issues regarding the village income and expenditure budget and examines the factors that influence their response styles. The data for this study consists of newspaper articles in local newspapers from 2014 to 2022. The findings identify two conflict resolution styles of headman and village legislature that are commonly used: unilateral action and seeking third-party intervention. Meanwhile, in the third style, measures for conflict resolution formulated through regulations do not feature in the newspaper reporting. Furthermore, the findings also identify some underlying causes for the conflict resolution styles that are used in this context, including mechanisms and actors. This study will contribute to the literature about post-conflict grassroot efforts in Aceh and formulate a more effective early warning system at the local level.AbstrakArtikel ini membahas tentang pola respons keuchik dan tuha peut terhadap konflik pengelolaan Anggaran Pendapatan dan Belanja Gampong (APBG).

Energy Crisis and Entrepreneurial Failure
Authors: ENE (VASILE) CRISTINA MARIANA
Published: July 2023

The author starts from the notion of a deterministic, causality-based model with which we can analyse phenomena of the Romanian economy that finds itself under the impact of a couple of crises. The two years of the pandemic have generated numerous dysfunctions and imbalances in various integrated markets. As we survey the Romanian business environment, their impact is visible. Emphasis is put on the pressure of certain crises pertaining to a range of factors such as: the pandemic, the workforce, energy, finance etc., which lead to unemployment, inflation, bankruptcy, and the decline of the quality of life. At the heart of the paper, we analyse the impact of the energy crisis on the business environment, public institutions, and population. The network of interconnected negative effects is highlighted through the state of entrepreneurial failure. In the conclusion of this paper, the effects that lead to the reduction of the quality of life in Romania are underscored.

The article describes the events of 1906 related to the publishing of the results of several accidental discoveries from the Golden Horde age in the Stavropol Governorate area by A.A. Spitsyn. In 1887 and 1890, the Imperial Archaeological Commission received several accidental findings from the nearby area of Roguly, Kievsky, Zdvizhensky, Beshpagir villages and the tract of Gashun Usta. A.A. Spitsyn published the most important ones in 1906. The article presents the materials from the archives of the Institute for Material Culture History first published by the researcher. The bronze mirrors from the nearby areas of the Roguly and Beshpagir villages are made public for the first time. Materials from the archive allowed to determine the contents of the findings from the “Koltsov” mound and the mound of the Yun-baba mountain. The authors attempt to localize most of the listed findings. The published materials also add to the already existing knowledge of the culture of the inhabitants of Stavropol Plateau in the age of the Golden Horde reign.
“I Do Love / To Note and to Observe”: The Pleasures of Surveillance and Resistance in the Work of Ben Jonson
Authors: Miele Benjamin
Published: July 2023

Poet, playwright, religious dissident, and collaborator with the state surveillance apparatus: Ben Jonson experienced a long and tortuous relationship with surveilling in late-Tudor/early-Stuart England. The cultures of surveillance he encountered extended beyond espionage to social and religious surveillance, which in early modern England often bled into and facilitated the workings of the state’s network of informants. His literary output and unusually detailed (for the time) biographical information combine to give us a complex picture of his engagement with surveilling, secrecy, and resistance. Jonson’s experience of surveillance involved incarceration and the threat of corporal punishment, but in his writings, he associates surveilling and being surveilled with pleasure in the context of his Humanist education, his conversion to Catholicism at a time when the Protestant English state had outlawed such worship, and his work as a satirist, playwright, and poet. Using Freud’s notion of unheimlich, or the uncanny, I argue that Jonson demystifies surveilling, but approaches his critique from two directions simultaneously: he interrogates and encourages resistance to state violence and coercion while highlighting his own acquiescence to the pleasures of voyeurism and exhibitionism, suggesting that surveilling is seemingly irresistible, as in both overpowering and appealing. Because he centers the uncanny in his writings, Jonson may be a useful guide for those theorizing and navigating the complexities of surveillance. He exemplifies how resistance to asymmetries of power persists through time and despite outward conformity to a regime of surveillance, which itself may be unheimlich.
Contested Care: COVID-19 Surveillance and Health Data in the Workplace
Authors: Metcalf Kathryne , Irani Lilly , Uribe del Águila Verónica
Published: July 2023

Within the ongoing disruption of the COVID-19 pandemic, technologically mediated health surveillance programs have vastly intensified and expanded to new spaces. Popular understandings of medical and health data protections came into question as a variety of institutions introduced new tools for symptom tracking, contact tracing, and the management of related data. These systems have raised complex questions about who should have access to health information, under what circumstances, and how people and institutions negotiate relationships between privacy, public safety, and care during times of crisis. In this paper, we take up the case of a large public university working to keep campus productive during COVID-19 through practices of placemaking, symptom screeners, and vaccine mandate compliance databases. Drawing on a multi-methods study including thirty-eight interviews, organizational documents, and discursive analysis, we show where and for whom administrative care infrastructures either misrecognized or torqued (Bowker and Star 1999) the care relationships that made life possible for people in the university community. We argue that an analysis of care—including the social relations that enable it and those that attempt to hegemonically define it—opens important questions for how people relate to data they produce about their bodies as well as to the institutions that manage them. Furthermore, we argue that privacy frameworks that rely on individual rights, essential categories of “sensitive information,” or the normative legitimacy of institutional practices are not equipped to reveal how people negotiate privacy and care in times of crisis.

Published: July 2023

Following the events of the summer of 2020, public and private sector organizations have engaged in a variety of actions related to promoting, valuing, and celebrating diversity, equity, and inclusion (DEI). Perhaps due to their role as direct providers of public safety, local governments are along the front lines of DEI efforts and values. Using a novel dataset of International City/County Management Association job advertisements from July 1, 2020–November 1, 2020, this article examines why some local hiring authorities utilize DEI signaling language in their job advertisements while others do not. Results indicate that both external and internal characteristics are associated with diversity value signaling in local government administrations.

Published: July 2023

Approximately 15% of all couples all over the world suffer from difficulty conceiving their first child. The word "infertility" is used to describe this problem.
When a couple had  regular, unprotected sexual intercourse for a year or longer, it indicates that they have been unsuccessful in their efforts to conceive.
      The current investigation aims to find out if there is a relationship between PROTAMIN-1(PRM-1) and INTERLEUKINE-12 (IL-12) gene expressions and their effect on the development of infertility. The current investigation comprised 100 teratozoospermia patients and 100 healthy fertile controls who had their semen examined. Samples were given by Al-Nahrain University's Biotechnology Research Center and the Kamal Al-Samarie IVF Hospital in Baghdad, Iraq. Determinations Reverse Transcription quantitative Polymerase Chain Reaction (RT-qPCR) was employed to test the expression of the PRM gene in semen and blood samples, as well as the IL-12 gene in blood samples. And the titer of IL-12 was evaluated in the seminal plasma employing the Enzyme Linked Immune Sorband Assay (ELISA) technique. The difference between the mean threshold cycle (ΔCt) of PRM-1 and IL-12 mRNA in the infertile patient group versus the healthy control group was also statistically significant. Evaluating the means of 2 ̄ΔΔCt   revealed an important finding,  a decrease in the expression of PRM-1 mRNA in the infertile group in comparison to the control group in the two types of samples. Conversely, there was an increase in the expression of IL-12 mRNA between the two study groups. In infertile Iraqi men, the expression of the PRM-1 gene was found to be down-regulated, whereas the expression of the IL-12 gene was found to be up-regulated. Our data revealed the diagnostic value of these genes and might be considered as predictive biomarkers in infertile people with idiopathic infertility.
Numerical Investigation in Nitinol Lattice Stability and Safe Usage in Replacing Hard Tissue
Authors: Hiadrah Soha S. , Al shadidi Zina A.
Published: July 2023

NiTi (also called Nitinol) transforms from cubic (austenite) to monoclinic (martensite), and vice versa, owing to the shape memory effect and superelasticity. Nitinol has a large number of biomedical applications because of its low elastic modulus close to that of natural bone material and good resistance to corrosion and fatigue, in addition to the transformation temperatures of nitinol that are close to body temperature. It has many other important applications, such as in the aircraft industry. In all these important applications, especially medical applications, Nitinol stability is an important factor for safety. Our goal is to study the stability of NiTi by calculating the phonon dispersion relation to obtain an accurate understanding of the mechanically unstable phases of the NiTi alloy.  The dispersion relation for the cubic and monoclinic phases was studied and coded using MATLAB to make a clear consideration of the dispersion relation and its optical and acoustic branches. Moreover, the density of the state and energy from the lattice vibrations were calculated.
     The crystal is found to be stable by the anharmonic part of the interactions. The austenite phase is stable up to (300 K). While it is not above (300 K). Any extra energy due to temperature changes caused the transformation to the martensite phase. The positive phonon modes indicate that the monoclinic phase is stable against energy perturbations. When the thermal vibration energy was calculated for the cubic phase and in the case of the monoclinic phase at T= 300 K. In both cases, it was less than 5 eV. There are no broken bonds owing to the energy of vibration.

Authors: Rauuf Aws Faisal , Aadim Kadhim A.
Published: July 2023

In this work, lead oxide (PbO) thin films were deposited using D.C. sputtering method on a surface of glass substrates and then thermally annealed at a temperature of 473K with annealing times of (1,2 and 3) hours. The structural, morphological, and optical properties of films were determined using X-ray diffraction (XRD), atomic force microscopy (AFM), FT-IR, and UV-Visible spectroscopy. The structure studies confirmed that PbO films are polycrystalline structures in an orthorhombic phase with average grain size (24.51, 29.64, 46.49, 16) nm with increasing annealing time. From AFM, the roughness of the film surface  (3.26, 1.76, 1.61, 1.79) nm as the film annealing time increases. The optical band gap values of the PbO thin films are (3.9, 2.8, 3.7, 2.4) eV as the annealing time increases.

Authors: Mohammed Israa Imad , Alsultan Hamid A. A.
Published: July 2023

The Nahr Umr Formation is considered one of the main reservoirs produced in southern Iraq. It is one of the important siliciclastic deposits of the Cretaceous sequence of Iraq oilfields. Zubair oil fields ZB-190 and ZB-047 were chosen to study areas. This study depends on the available core and cutting samples to determine the facies analysis, depositional environments, petrographic characteristics and diagenesis processes. Based on the description of the core and the borehole, six types of facies were distinguished in the Nahr Umr Formation, resulting in an intercalated sandstone and shale with a thin layer of siltstone. The petrographic study of the clastic part of the Nahr Umr Formation showed that the sandstone is composed mainly of quartz arenite. Diagenesis processes affecting the Nahr Umr Formation are two types compaction and cementation processes. The sedimentary environment of the Nahr Umr Formation was represented by the deltaic fluvial environments. These environments appear in the central and southwestern parts of the study area. Sequence stratigraphy in the Nahr Umr Formation is beginning by sequence boundary type one (SB1) and sequence boundary type two (SB2) that appeared in the upper part of the formation. The other surfaces were represented by the end of the deposition of the Nahr Umr Formation and the emergence of the transgressive ravinement surface (TRS) within the transgressive system tract (TST)and The maximum flooding surface (MFS) was distinguished in the middle of the formation and each of these surfaces has a lateral extension along the study section.

Computation of the Relationships of X-ray to Radio Luminosities of a Sample of Starburst Galaxies
Authors: Zamal Maha M. , N. Al Najm M.
Published: July 2023

The goal of this research is to better understand the physical features of starburst galaxies. Radio and X-ray observations are good for exploring the stuff within the central regions of galaxies.  A galaxy that is undergoing a strong star formation, usually in its central area, is known as a starburst galaxy. This paper provides the results of a statistical analysis of a sample of starburst galaxies. The data used in this research have been collected from NASA Extragalactic Database (NED), and HYPERLEDA. Those data have been used to examine possible luminosity correlations of X-ray to a radio of a sample of starburst galaxies. In this research, statistical software, known as statistic-win-program, has been used to investigate if there is a luminosity correlation between multiple-wavelength bands. The results of the statistical analysis conclude that there is a good correlation between X-ray luminosity and radio luminosity at 1.4GHz where the partial correlation coefficient is (R≈0.53) and slope (0.6±0.12). There is also a good correlation between X-ray luminosity and radio luminosity at 5GHz with a good partial correlation coefficient (R ≈ 0.65) and slope (0.77±0.11).  There are good positive relationships between radio luminosity at (1.4GHz, 5GHz) with infrared and far-infrared luminosities (Log L1.4GHz α log LFIR0.89±0.04 α Log LIR0.9±0.03) with a very strong correlation equal to R=0.9 (Log L5GHz α Log LFIR0.79±0.05 α Log LIR0.81±0.05) with strong correlation R=0.8 both with very high probability level p≈10-7. One of the closest and most ubiquitous correlations known among the global features of local star formation and starburst galaxies is the link between far-infrared (FIR) and radio emission.
Detection of Abnormal electrocardiograms Based on Various Feature Extraction methods
Authors: Ahmad Khorsheed Eman
Published: July 2023

Electrocardiogram (ECG) is a graphical representation of the electrical activity of the heart obtained by placing various electrodes on specific areas of the subject's body surface. Abnormalities in a patient's ECG signal may indicate cardiac diseases that require immediate medical attention. As a result, detecting an abnormal ECG is critical for the patient's benefit. This work develops a method for classifying ECG signals as normal or abnormal. In this paper, we propose a method for detecting cardiac arrhythmias in electrocardiograms (ECG). In the first stage, the proposal focuses on various feature extractor methods. The Fourier Transform (DFT), Discrete Wavelet Transform (DWT), and Improved complete ensemble empirical mode decomposition with adaptive noise were the feature extraction techniques evaluated (ICEEMDAN). The PCA method is then used to reduce the number of features. Finally, for classification, the Support Vector Machine (SVM) was used, which was trained using the features extracted in the first stage. The proposed models are tested using datasets from MIT-BIH arrhythmia and PTB Diagnostics. The experimental results show that using 3-PCs with the DWT method produces better results than the other methods, which achieve 98.7% in terms of accuracy.
