Willingness to pay for green energy sources in the United Arab Emirates (UAE)
Authors: Tadele Haileslasie , Kalyebara Baliira
Published: April 2023

This study investigates the willingness of customers in the UAE to pay a premium for green energy (GE) sources. Given the huge initial investment required for GE projects, raising capital is often achieved by increasing energy bills or taxes. To explore this issue, the study surveyed 192 small and medium-sized businesses using the contingent valuation method. The results indicate that while most businesses are aware of solar and wind energy sources and the importance of combating climate change, half of them are not willing to compromise their current energy use and do not support an increase in utility bills or taxes to finance GE projects. However, older businesses tend to be more willing to pay a premium for GE compared to younger businesses. Overall, majority of the businesses support a voluntary increase in electricity bills. The findings highlight the crucial role of current electricity bills and knowledge about GE sources in shaping customers' willingness to pay. This study contributes to the literature on energy finance and the contingent valuation method in the context of green energy in the UAE.

Published: April 2023

Background: Cigarette smoke contains a lot of free radicals that can reduce antioxidants in the body. One of those is Reactive Oxygen Species (ROS) which can induce Retinal Ganglion Cell (RGC) apoptosis. Reduced ganglion cell axons will eventually lead to optic neuropathy. Supplementing herbal medicines, vitamins, foods, and drinks containing antioxidants is one way to increase oxidant levels in the body. Roselle or Hibiscus sabdariffa is a herbal plant reported to have a lot of antioxidant content.Objective: The study aimed to prove that Roselle flower infusions can reduce retinal ganglion cell apoptosis of Sprague Dawley rats exposed to cigarette smoke.Methods: This was an experimental study with a post-test-only design with a total of 24 male Sprague Dawley rats exposed to four non-filtered cigarettes/day for 30 consecutive days. They were randomly divided into four sub-groups, and each group consisted of 6 rats. The control group received 1 ml of saline, and three treatment groups received Roselle flower infusions of 2.5%, 5%, and 10% for 30 days. Enucleated eyes were then made paraffin blocks and slides with HE staining. The retinal ganglion cell apoptosis score was assessed by calculating the number of apoptotic cells using 1000x in five fields of view. The data were analyzed using Kruskal-Wallis non-parametric test followed by the Mann-Whitney U test.Results: The average retinal ganglion cell apoptosis score in control, treatment 1, 2, and 3 groups were 3.00; 2.83; 2.00; 1.83. There was a significant difference between the control group and treatment groups 2 (p=0.001) and group 3 (p=0.001), while between the control group and treatment group 1, there was no significant difference (p=0.317).Conclusion: The administration of 5% and 10% Roselle flower infusions can reduce the apoptosis score of retinal ganglion cells in Sprague Dawley rats exposed to cigarette smoke. The higher the Roselle flower infusion concentration, the lower the apoptosis score of retinal ganglion cells.
Environmental factors promoting the effective use of a computer-assisted clinical case for second-year osteopathic medical students
Authors: Baer Robert W. , Chamberlain Neal R.
Published: April 2023

Computer-aided clinical cases (CACC) have the potential to complement and/or supplement other types of problem-based learning exercises in modern medical curricula. Deploying a CACC learning experience requires institutional commitment to technology and a belief by administration, faculty, and students that “climbing a steep growth curve” is worth the effort. Several aspects of the institutional environment at the Kirksville College of Osteopathic Medicine (KCOM) led to the development of the CACC exercise described in this article, including the need to design a uniform, supplemental, Internet-based learning experience and assessment exercises for students doing clinical rotations at off-site facilities. The CACC learning experience was enthusiastically accepted by second-year medical students as an integrative and clinically relevant educational experience. The success of this CACC exercise has helped to promote the development of other innovative applications of technology to medical education at KCOM.
Benefits of direct glomerular filtration rate (GFR) determination versus creatinine-based tests for evaluating renal function
Authors: Cimmino Christopher J.
Published: April 2023

To diagnose renal disease earlier and thereby reduce the number of patients with end-stage renal disease, accurate, specific diagnostic tests are necessary. The author explains the benefits of using tests that rely on the glomerular filtration rate measurement rather than on traditional creatinine-based diagnostic tests.
Manipulative treatment of carpal tunnel syndrome: Biomechanical and osteopathic intervention to increase the length of the transverse carpal ligament
Authors: Sucher Benjamin M. , Hinrichs Richard N.
Published: April 2023

To quantify the amount of transverse carpal ligament (TCL) elongation in response to osteopathic manipulation or sustained load bearing (or both), a study involving seven cadaver limbs was conducted. Distances from the trapezium to the hamate (distance A) and from the scaphoid to the pisiform (distance B) were measured in five mounted cadaver limbs during and after the limbs bore the weight (2 newtons [N] to 4 N) for 2 several-hour periods. A several-hour period occurred between the weight bearing to assess recoil. Distances A and B were measured before and after the limbs were manipulated, according to previously described techniques, as well as with a new maneuver, termed the “guy-wire” technique. Two dissected limbs also were subjected to further weight bearing, this time increased to 8 N. Greater weight loads produced greater lengthening of the TCL, and recoil after removal of weight loads was slower than recoil after manipulation. Manipulation was more effective than weight loading for increasing distance A (distal canal), but weight loading generally was more effective than manipulation for increasing distance B (proximal canal). The guy-wire manipulation combined with direct transverse extension appeared to have the greatest impact on lengthening the TCL distally. These results show promise for the effective use of manipulation and load bearing for TCL elongation and nonsurgical relief of pressure on the median nerve in patients with carpal tunnel syndrome.
Domestic violence: A primer for the primary care physician
Authors: Konchak Peter S.
Published: April 2023

Domestic violence is a serious, complex, public health problem, which is more common than many physicians realize. Although certain characteristics may be associated with the victim and perpetrator, they have limited value in identification or prediction of partner violence. Any woman may be a victim and any man, a perpetrator; therefore, universal screening for partner abuse is encouraged. The medical and psychological consequences of domestic violence are often of tragic proportion, for both the woman and her children. Unfortunately, unless asked directly and in a supportive fashion, many women will remain silent and continue to be victimized.
The intertextuality of argumentation: a semiotic approach to academic writing in higher education
Authors: Ma James
Published: April 2023

The importance of argumentation in academic writing, while historically recognised, has arguably lost prominence alongside the rapid expansion of higher education since the early 1990s in the UK. This has been exacerbated by an increasingly prevalent technological intervention in teaching and learning processes. With this as a background, this article presents a semiotic analysis of student dissertation extracts to illustrate the role of intertextuality in governing interpretative, evaluative, and concluding propositions in argumentation. Each proposition is perceived as indexed to syntactical compositionality by which a previous proposition elicits a present one that awaits a future one, thus forming a line of argument. The analysis teases out what is at stake concerning the interdependence of signifying codes in textual relations and functions. This brings into view a network of sign actions that lends itself to instances of signification in mediating and coordinating propositions in argumentation. The article concludes with reflection on the medium of English as a lingua franca for studies in higher education, highlighting a semiotic understanding of the intertextuality of argumentation in academic writing.
Bone growth and body weight patterns in juvenile raccoon dogs in Wakayama Prefecture, western Japan
Authors: Takatsuki Seiki , Suzuki Kazuo
Published: April 2023

Information on growth of the Japanese raccoon dog, Nyctereutes procyonoides is limited. We collected 237 juvenile raccoon dogs, road-killed and culled for pest control in Wakayama Prefecture, western Japan from 2002 to 2019. We measured the skull, mandible, femur lengths, and body weights of all specimens and used the body weights of healthy animals (n = 136). We found that these variables increased rapidly up to September and reached maximum values in October. Evidence of dorsal surface roughness of the neurocranium became obvious in October, and up to 35 % of individuals had rough dorsal surfaces of neurocranium in December. Epiphyseal fusion of femurs appeared in September, and 27 % of specimens having fused femurs was recorded in December. This study firstly described the growth patterns of the Japanese raccoon dogs based on a lot of samples.

In this study, we determined the diagnostic performance of adding ultrasound (US) with/without fine‐needle aspiration cytology (FNAC) to computed tomography (CT)/magnetic resonance imaging (MRI) in evaluating neck lymphadenopathy (LAP) in patients with head and neck cancer treated with irradiation. We included 269 patients who had neck LAP after radiotherapy (RT) or concurrent chemoradiotherapy (CCRT) resulting from cancers of the head and neck region between October 2008 and September 2018. The diagnostic methods consisted of the following: 1) CT/MRI alone, 2) CT/MRI combined with a post-RT US predictive model, and 3) CT/MRI combined with US + FNAC. We compared their diagnostic performance using receiver operating characteristic (ROC) curves. In total, 141 (52%) malignant and 128 (48%) benign LAPs were observed. Regarding the diagnostic accuracy, the area under the ROC curves was highest for the combined CT/MRI and US + FNAC (0.965), followed by the combined CT/MRI and post-RT US predictive model (0.906) and CT/MRI alone (0.836). Our data suggest that the addition of a US examination to CT/MRI resulted in higher diagnostic performance than CT/MRI alone in terms of diagnosing recurrent or persistent nodal disease during the evaluation of LAP in patients with irradiation-treated head and neck cancer.

Published: April 2023

Immune cells are indispensable defenders of the human body, clearing exogenous pathogens and toxicities or endogenous malignant and aging cells. Immune cell dysfunction can cause an inability to recognize, react, and remove these hazards, resulting in cancers, inflammatory diseases, autoimmune diseases, and infections. Immune cells regulation has shown great promise in treating disease, and immune agonists are usually used to treat cancers and infections caused by immune suppression. In contrast, immunosuppressants are used to treat inflammatory and autoimmune diseases. However, the key to maintaining health is to restore balance to the immune system, as excessive activation or inhibition of immune cells is a common complication of immunotherapy. Nanoparticles are efficient drug delivery systems widely used to deliver small molecule inhibitors, nucleic acid, and proteins. Using nanoparticles for the targeted delivery of drugs to immune cells provides opportunities to regulate immune cell function. In this review, we summarize the current progress of nanoparticle-based strategies for regulating immune function and discuss the prospects of future nanoparticle design to improve immunotherapy.
Simultaneous aerodynamic and structural optimisation of a low-speed horizontal-axis wind turbine blade using metaheuristic algorithms

Published: April 2023

This work presents a concurrent design and multi-objective optimisation framework of horizontal axis wind turbine blades, made of composite material, for low wind speed. The optimisation model aims to minimise the structural mass of the blade whilst simultaneously maximising the turbine power output, subjected to three constraints viz. blade tip deflection, and Tsai-Hill and von Mises criteria. The design variables are blade shape and details of the internal blade structure. The control points and polynomial interpolation technique were adopted to determine the blade shape while the airfoil types at blade sections remained fixed. The internal blade structure design variables include the thickness of ribs and spars and the carbon fibre thickness and orientations. The blade element momentum approach is utilised to calculate turbine power and structural loads, whereas a finite element method is employed for structural analysis. Twelve multi-objective metaheuristics algorithms are used to solve the proposed multi-objective optimisation problem while their performance is investigated. The results obtained show that the multi-objective cuckoo search algorithm is the most efficient method. This study is said to be the baseline for a future study on multi-objective optimisation which combines two design stages of the composite low-speed wind turbine blades.
The representation of multilingualism in dubbing and subtitling for the deaf and hard of hearing (SDH)
Authors: Rezvani Sichani Behnam , Afrouz Mahmoud , Moinzadeh Ahmad
Published: April 2023

Multilingualism serves an important function in the characterization of an audiovisual product; thus, its representation in translations demands scientific attention. The task of rendering multilingualism in translation becomes more complicated when no or limited access to the original audio content is possible. This being so, this study investigates the representation of multilingualism in English subtitles for the deaf and hard of hearing (SDH) and Persian dubbing of four polyglot films. It examines and discusses the strategies adopted by translators in eight translations, both the SDH and dubbed versions. The results indicate that translators employ a variety of solutions and strategies to tackle challenges and render the third language (L3), but still dubbing tends to neutralize L3 in most instances. In the case of SDH, L3 was made explicit, but the high frequency of homogenising strategies and the loss of L3 in the translations were noticeable. These results could be of use for both cinema and translation professionals and non-professionals, particularly for enhancing media accessibility (MA) for the deaf and hard of hearing (DHH) community, besides adding to the body of studies on the translation of multilingualism.

Infrared camouflage is an effective technique to avoid many kinds of target detection by detectors in the infrared band. For a high-temperature environment, thermal management of selective emission is crucial to dissipate heat in the mid-infrared non-atmospheric window (5–8 μm). However, it still remains challenges for balancing infrared camouflage and thermal management. Here, we experimentally demonstrate a multilayer film structure (MFS) for infrared camouflage with thermal management. Combining the ideal emission spectrum and genetic algorithm (GA), the inverse-design MFS containing 7 layers of five materials (SiO2, Ge, ZnS, Pt and Au) has been designed. Based on the hierarchical metamaterial, the optimized MFS has high performance of infrared camouflage to against the lidar detection in the near-infrared band. The experimental results reveal the high compatible efficiency among thermal camouflage (ε
3–5μm = 0.21, ε
8–14μm = 0.16), laser stealth (ε
1.06μm = 0.64, ε
1.55μm = 0.90, ε
10.6μm = 0.76) and thermal management (ε
5–8μm = 0.54). Therefore, the proposed MFSs are attractive as basic building block of selective emitter, for the application of advanced photonics such as radiative cooling, infrared camouflage, and thermal emission.

Analyzing Drop Jump Ground Reaction Forces in Microsoft Excel
Authors: Pedley Jason S. , Radnor John M. , Lloyd Rhodri S. , Oliver Jon L.
Published: April 2023

Analysis of ground reaction forces during a drop jump can provide greater insight into stretch-shortening cycle function and jump-landing strategy than performance metrics such as jump height, ground contact time, and reactive strength index. Commercially available force plates have customized processing software capable of calculating many variables, but this software can be cost-prohibitive for many academics and practitioners. Using the accompanying spreadsheet outlined in this article, any professional can quickly process force plate data and enhance their assessment of an athlete's stretch-shortening cycle function and plyometric performance to guide future training objectives.

Authors: Paiva Samara dos Santos , Silva Erika Lorena Ramos de Oliveira , Martins Gisele
Published: April 2023

Objective: to map the evidence on web-based technologies and their applicability in outpatient and home care in pediatric urology. Methods: this is a scoping review, with searches conducted in six databases, with no time limit, in Portuguese, English, and Spanish. Results: 2,200 articles were obtained, with 19 publications eligible for the final sample. The most used web-based technologies were telehealth and telemedicine (47.3%), online intervention programs (21.0%), and mobile apps (15.8%), with a lower rate of use of serious games, social media, and urination videos (5.3%), mostly in the home setting. Conclusion: the mapping of technological evidence in outpatient and home care in pediatric urology allowed us to identify the types of technology and their applications focused on self-management of symptoms and self-efficacy, for monitoring and follow-up of urologic care. Contributions to practice: the synthesized evidence contributes to an expanded, qualified, and innovative professional practice with the pediatric population with urinary and bowel symptoms, characteristics related to advanced nursing practice, in addition to favoring early diagnosis and greater therapeutic adherence, particularly by supporting interventions tailored to the needs of the pediatric patient and his family.

In some primaries, African American race/ethnicity predisposes to higher stage and worse survival. We tested for differences in cancer-specific mortality (CSM) and other-cause mortality (OCM) in patients with adrenocortical carcinoma (ACC) according to African American vs Caucasian race/ethnicity. We hypothesized that African Americans present with higher tumor stage and grade, do not receive the same treatment, and experience worse oncological outcomes than Caucasians. Within Surveillance, Epidemiology, and End Results database, we identified 1016 ACC patients: 123 (12.1%) African Americans vs 893 (87.9%) Caucasians. Propensity score matching (PSM) (age, sex, marital status, grade, T, N, and M stages, and treatment type), Poisson-smoothed cumulative incidence plots, and competing risk regression (CRR) were used. Compared to Caucasians, African Americans were more frequently unmarried (56.9% vs 35.5%, P < 0.001). No clinically meaningful or statistically significant differences were observed for age, grade, T, N, and M stages, as well as treatment type (all P > 0.05). After PSM (1:4), 123 African Americans and 492 Caucasians remained and were included in CRR analysis. In multivariable CRR models, CSM and OCM rates were not different between the two race/ethnicities (hazard ratio: 0.84, P = 0.3). In African Americans, 5-year CSM rates were 31.2% and 75.3% in European Network for the Study of Adrenal Tumors (ENSAT) stages I-II and III-IV, respectively vs 32.9% and 75.4% in Caucasians. Overall 5-year OCM rates were 11.0% vs 10.1% in respectively African Americans and Caucasians. Unlike other primaries, in ACC, African American race/ethnicity is not associated with higher disease stage at initial diagnosis or worse survival.
Las prácticas de subsistencia de las sociedades cazadoras-recolectoras del noroeste de la Patagonia argentina a lo largo del Holoceno
Authors: Cordero José Agustín
Published: April 2023

La explotación del guanaco (Lama guanicoe) como recurso principal –proveedor no sólo de carne y grasa sino también materia prima para la confección de varios tipos de instrumentos, de vestimentas y de viviendas– ha variado a lo largo del Holoceno en el noroeste de la Patagonia. El siguiente trabajo analiza la información disponible y propone un modelo explicativo que da cuenta de las prácticas de subsistencia de las sociedades cazadoras-recolectoras que habitaron el área de estudio durante este período. Al inicio del Holoceno existían dos modos de vida con economías marcadamente diferentes. Los primeros ocupantes de la estepa, que basaban su subsistencia en la obtención del guanaco con una tecnología de puntas de proyectil, se extendieron a la zona ecotonal, donde los grupos con una tecnología sencilla hecha en materias primas locales explotaban principalmente animales medianos y chicos y poco guanaco. La explotación del guanaco se generalizó a mediados del Holoceno en el ecotono y la estepa, pero siempre se complementó con fauna menor, vegetales, moluscos y peces. En el tránsito de los últimos 2.000 años, la cantidad de especies explotadas aumentó significativamente junto con la diversidad.
El uso de los recursos faunísticos entre los cazadores-recolectores de Patagonia: tendencias espacio/temporales de las estrategias durante el Holoceno
Authors: Miotti Laura
Published: April 2023

En Argentina, el problema de la intensificación de recursos ha sido tratado más profundamente en los últimos años, sólo en algunas regiones. En este trabajo se analiza el problema por Fajas latitudinales, con el resultado final que en el único sector de Patagonia que podríamos referir los casos arqueológicos a un modelo de intensificación es en Patagonia norcentral y en Tierra del Fuego, mientras que en Patagonia meridional, otros modelos responden mejor (extensificación, diversificación). La búsqueda de variables y procesos nos permite sugerir que la historia de la intensificación/extensificación varía notablemente en las diferentes zonas específicas hacia el Holoceno tardío, lo cual implica que no podemos utilizar un único modelo para comprender el registro arqueológico.
Dando un uso a los «indeterminados»: un marco de referencia específico para la zooarqueología de contextos históricos hispanocriollos
Authors: Marschoff María
Published: April 2023

La propuesta de este trabajo es explorar las posibilidades que brinda el uso de muestras identificadas a nivel anatómico en nuestros análisis e interpretaciones acerca de la composición y distribución de restos arqueofaunísticos en contextos domésticos de momentos históricos. A partir de la construcción de un marco de referencia específico para la culinaria hispana de los siglos XVI a inicios del XIX, mostramos cómo es posible abordar las prácticas alimentarias de contextos domésticos sin necesidad de alcanzar el nivel de identificación taxonómica, lo cual consideramos especialmente útil para muestras muy fragmentadas. Ilustramos el alcance de este modelo a través del análisis de dos espacios de habitación diferentes de la colonia española de Floridablanca, San Julián, Santa Cruz, Argentina (1780-1784).
Intensificación en el sur de Mendoza: un enfoque avifaunístico
Authors: Giardina Miguel Ángel
Published: April 2023

En el presente trabajo se aborda el significado de la avifauna, discutiendo su patrón temporal en términos de variaciones en amplitud de dieta humana pre-hispánica en Mendoza. Se evalúa el comportamiento representado en los diferentes conjuntos analizados, utilizando variables temporales y espaciales de NTAXA, índices de diversidad, heterogeneidad y abundancia de camélidos. Entendiendo a la intensificación como un proceso que genera un incremento en la cantidad de energía obtenida por superficie, se propone una tendencia en el registro zooarqueológico con un aumento de la diversidad taxonómica en torno a los 2000 años AP. Dicho proceso ha sido interpretado como un aumento en la amplitud de dieta producto de un proceso de intensificación regional. Sin embargo, esta tendencia no se verificaría en todos los ecosistemas del sur de Mendoza.
Análisis arqueomalacológico de tres contextos rituales de la necrópolis púnica de Cádiz
Authors: Mesa Hernández Eduardo M. , Niveau de Villedary y Mariñas Ana María
Published: April 2023

La muestra malacológica estudiada pertenece a tres contextos rituales contemporáneos de época bárcida (finales del s. III a.C.) procedentes de un sector recientemente excavado de la necrópolis púnica de Cádiz. La investigación arqueológica ha puesto de manifiesto la particular frecuencia de ofrendas de tipo marino en la necrópolis púnica de Cádiz, interpretadas bien como ofrendas alimentarias, o bien como comidas o «banquetes» funerarios. El presente trabajo trata de ahondar en el debate generado en torno al sentido y significado de estos restos en contextos rituales púnicos. A través de las muestras analizadas se han distinguido dos producciones diferenciadas que evidencian un sentido ritual distinto. Por un lado, los restos derivados de una producción de carácter alimenticio y, por otra parte, los que presentan un significado «económico-simbólico», que nos habla de la posible estandarización del culto o ritual funerario fenicio-púnico.

Published: April 2023

La entrada a la Galería Sur de la Cueva del Toll (Moià, Barcelona) fue descubierta en los años 40 del pasado siglo. Desde entonces, las distintas intervenciones realizadas han puesto de manifiesto la importancia del yacimiento arqueo-paleontológico tanto a nivel regional como peninsular. Centrándonos en los niveles holocenos de la cavidad, las investigaciones realizadas indican un uso prolongado de la misma, al menos desde el Neolítico Antiguo, hasta finales del Bronce inicial. Entre la variada cantidad de materiales recuperados destacan por el interés del presente estudio, varios restos de malacofauna marina. En el marco del actual proyecto de investigación, han sido recuperados nuevos ejemplares pertenecientes a las especies Columbella rustica y Nassarius cuvieri. El análisis tecnológico, traceológico y químico de las mismas sugiere que fueron modificadas antrópicamente mediante la realización de perforaciones para su uso, siendo tintadas con pigmentos rojizos. La posición estratigráfica y espacial de los ejemplares nos lleva a interpretar las mismas como parte de un único abalorio, depositado en el fondo de una estructura neolítica.
Purification and characterisation of thermostable α-amylases from microbial sources
Authors: Lim Si J. , Hazwani-Oslan Siti Nur , Oslan Siti N.
Published: April 2023

α-Amylases (E.C 3.2.1.1) hydrolyse starch into smaller moieties such as maltose and glucose by breaking α-1,4-glycosidic linkages. The application of α-amylases in various industries has made the large-scale productions of these enzymes crucial. Thermostable α-amylase that catalyses starch degradation at the temperatures higher than 50 °C is favourable in harsh industrial applications. Due to ease in genetic manipulation and bulk production, this enzyme is most preferably produced by microorganisms. Bacillus sp. and Escherichia coli are commonly used microbial expression hosts for α-amylases (30 to 205 kDa in molecular weight). These amylases can be purified using ultrafiltration, salt precipitation, dialysis, and column chromatography. Recently, affinity column chromatography has shown the most promising result where the recovery rate was 38 to 60% and purification up to 13.2-fold. Microbial thermostable α-amylases have the optimum temperature and pH ranging from 50 °C to 100 °C and 5.0 to 10.5, respectively. These enzymes have high specificity towards potato starch, wheat starch, amylose, and amylopectin. EDTA (1 mM) gave the highest inhibitory effect (79%), but Ca2+ (5 mM) was the most effective co-factor with 155%. This review provides insight regarding thermostable α-amylases obtained from microbial sources for industrial applications.
Childhood Obesity among Socioeconomically Vulnerable Families: A Path Model Using Parenting Behavior and Its Associates
Authors: Yang Hwa-Mi , Choo Jina
Published: April 2023

Using path analysis, we aimed to examine whether parenting self-efficacy and parenting styles would be significant associates with parenting behavior, and the parenting behavior would be significantly associated with the obesity status of children from socioeconomically vulnerable families.A cross-sectional study was conducted with 61 parents and their children enrolled in public welfare systems in a community in Seoul, South Korea. Parenting behavior was defined as encouraging a child’s healthy eating habits and was measured using the Child Feeding Questionnaire.In the path model, higher levels of parenting self-efficacy and lower levels of authoritarian parenting were significantly associated with a higher level of parenting behavior, which was significantly associated with lower child body mass index z-scores.Community health nurses need to provide intervention strategies for increasing parenting self-efficacy and decreasing authoritarian parenting styles to promote parenting behaviors and childhood obesity prevention among socioeconomically vulnerable families.
Case Report on Painful Patellar Crepitation Following a Knee Replacement with Preserved Patella
Authors: Butarbutar John Christian Parsaoran , Hananto Joshua Edward , Irvan Irvan
Published: April 2023

Patellar clunk crepitation is a well-known complication following knee replacement surgery and is associated with posterior stabilized knee replacement surgery and surgical technique. Currently, patellar clunk or crepitation management following knee replacement surgery with preserved patella remains unclear. The purpose of this case report is to discuss whether patellar clunk or crepitation management should include debridement with patellar resurfacing or debridement alone. This case describes a patellar crepitation after knee replacement surgery with the preserved patella. The surgery went uneventfully using the standard medial parapatellar approach. However, the patient was still unsatisfied with the chronic left knee pain (>3 months) and crepitation that developed following the surgery, and the patient was diagnosed with patellar clunk and crepitation (PCC). A patellar resurfacing procedure was performed with a satisfactory clinical outcome. Replicating the original joint line level and placing the tibial component posteriorly play a pivotal role in preventing PCC. Debridement and patellar resurfacing procedures are recommended in this type of case to overcome the valgus knee alignment and the placement of the tibial component.

Authors: Nasution Sri Wahyuni , Chairunnisa Chairunnisa
Published: April 2023

In providing the best health care to the community, hospitals as health care facilities utilize technologies that are influenced by developments and advances in medical sciences and technologies. One of such technologies is the information management technology. Since the quality of information processing is an essential factor for succesful medical care of patients, Regulation of the Minister of Health of the Republic of Indonesia Number 82 of 2013 requires all hospitals to implement a hospital information management system (HIMS). To assess the successful implementation of HIMS, various models and frameworks have been developed, including the HOT-FIT model. This study aimed to analyze the implementation of the hospital management information system at Langsa General Hospital, Aceh, Indonesia, using the HOT-FIT model which applied the SEM-PLS method. This quantitative study was performed in approximately three months using the HOT-FIT (company, technology-FIT human,) framework that includes nine variables of system quality, information quality, service quality, organization structure, facility situations, support from leadership, system usage, user satisfaction, and net benefits. Data analysis was performed using the SEM-PLS analysis in SmartPLS application (V.3.2.9). Results showed that human, organization, and technology supports were factors that influence the successful implementation of HIMS. To conclude, the HOT-FIT model can be used to identify the factors that influence the successful implementation of HIMS to inform the HIMS improvement in the hospital that will eventually improve the hospital’s quality system, information, service quality, and user satisfaction.

We present a learnability analysis of the argument-modifier distinction, asking whether there is information in the distribution of English constituents that could allow learners to identify which constituents are arguments and which are modifiers. We first develop a general description of some of the ways in which arguments and modifiers differ in distribution. We then identify two models from the literature that can capture these differences, which we call the argument-only model and the argument-modifier model. We employ these models using a common learning framework based on two simplicity biases which tradeoff against one another. The first bias favors a small lexicon with highly reusable lexical items, and the second, opposing, bias favors simple derivations of individual forms – those using small numbers of lexical items.
Our first empirical study shows that the argument-modifier model is able to recover the argument-modifier status of many individual constituents when evaluated against a gold standard. This provides evidence in favor of our general account of the distributional differences between arguments and modifiers. It also suggests a kind of lower bound on the amount of information that a suitably equipped learner could use to identify which phrases are arguments or modifiers.
We then present a series of analyses investigating how and why the argument-modifier model is able to recover the argument-modifier status of some constituents. In particular, we show that the argumentmodifier model is able to provide a simpler description of the input corpus than the argument-only model, both in terms of lexicon size, and in terms of the complexity of individual derivations. Intuitively, the argument-modifier model is able to do this because it is able to ignore spurious modifier structure when learning the lexicon. These analyses further support our general account of the differences between arguments and modifiers, as well as our simplicity-based approach to learning.
Nietzsche e Prinz

Published: April 2023

O objetivo do texto é não apenas explicar a contribuição da filosofia de Nietzsche no atual debate em torno da filosofia das emoções, por meio da aproximação teórica com o emocionismo de Jesse Prinz – especialmente da abordagem das emoções entendidas como sentimento –, mas, sobretudo, defender a tese da compatibilidade da abordagem cognitiva e não cognitiva das emoções. Assim, se por um lado, emoções são acompanhadas de sinais somáticos, por outro lado, emoções também representam preocupações (Prinz) ou avaliações (Nietzsche) sobre algo no mundo. A tese compatibilista auxilia na solução de duas sérias objeções ao sentimentalismo: a determinação do conteúdo das emoções e a individualização das experiências emocionais. Essa conclusão é mais bem compreendida, além disso, por meio da hipótese disposicional.
Material Bonuses for Combat and Service Activities of Fighters and Commanders of the Red Army (1918–1946)
Authors: Shunyakov Dmitry V.
Published: April 2023

Introduction. The article analyzes the experience of creating and improving the system of material bonuses for Red Army soldiers and officers of the Red Army during the Civil War, the interwar period and during the Great Patriotic War.

Materials and Methods. Collections of official documents, scientific literature, as well as sources of personal origin were used in the work. The study was conducted on the basis of the principles of historicism, objectivity and consistency. The need to consider material bonuses in the context of the activities of state bodies to motivate the combat activities of military personnel led to the use of the historical-systemic method.

Results. The study revealed a clear financial vertical from the central bodies of military administration (financial administration of the Red Army) through intermediate financial authorities in military formations to an individual soldier. Bonus money was issued at the choice of a serviceman either in banknotes or transferred non-cash to deposit books.

Conclusions. It is stated that material bonuses have led to an increase in professional skills through the personal interest of military personnel in the results of combat and service activities.
Dios, Patria y Democracia: el ideario de la Fuerza Democrática Nicaragüense (FDN) en El Libro Azul y Blanco de 1983

En septiembre de 1983 la comandancia de la Fuerza Democrática Nicaragüense (FDN) terminó la redacción de El Libro Azul y Blanco (LAyB). Dos mil ejemplares fueron impresos bajo el sello del Centro de Comunicaciones de la FDN. En 1984 fueron entregados a los combatientes que ingresarían a Nicaragua desde Honduras. Se trató de un código de conducta y un manual ideológico que buscó preparar a los combatientes en el trato con los pobladores y aprovechar esas oportunidades para explicarles su lucha y reclutarlos. En 2001, el documento fue desclasificado de los National Security Archives (NSA). El objetivo de este artículo es analizar el ideario de la FDN a través del LAyB con la finalidad de determinar las causas consignadas del levantamiento contrarrevolucionario, entender las estrategias planeadas para sumar adeptos armados a la Contra y la lógica de lucha, para esto último también se usan otros documentos contrarrevolucionarios producidos en la época.

A intervenção pedagógica e a inclusão de alunos no Espectro Autista no ambiente escolar é um desafio que demanda cada vez mais capacitação dos profissionais atuantes da Educação Infantil. A fim de auxiliar na compreensão de como os profissionais lidam com essa realidade, este estudo tomou como ponto de partida diversas proposições teóricas de autores que indicam os desafios e estratégias para inclusão no ambiente escolar e teve o objetivo de levantar as intervenções didáticas realizadas por educadores e relatadas em publicações científicas recentes. Para isso, foi elaborado um protocolo de pesquisa para a identificação de estudos de caso com intervenções pedagógicas com crianças com Transtorno do Espectro Autista (TEA), matriculados na Educação Infantil. A partir dos estudos selecionados foi realizada uma revisão de literatura integrativa. Os resultados mostraram que a abordagem lúdica tem sido a mais frequente, porém existe uma grande variedade de intervenções sendo realizadas de forma efetiva. As intervenções levantadas e as análises desses estudos fornecem importantes subsídios para a atuação de docentes, outros profissionais e pesquisadores de crianças com TEA.

The Applied mechanical and mathematical model of grinding of a solid particle by static crushing

Now crushers are one of the most common types of crushing equipment using the principle of a mechanical method of material destruction (for example, rollers, jaws, cone crushers, etc.). To provide effective parameters of the crusher, it is necessary to take into account the correlation between the physical and mechanical characteristics of the material (sizes, shapes, strengths, fragility, uniformity, etc.) and the energy parameters of the crusher (operation and power) at the design stage. The existing theories describing the mentioned dependence and relying on different classical hypotheses allow obtaining a very approximate (inaccurate) result. Consequently, it is necessary to develop a detailed theory of crushing capable of an accurate description of the mechanical process of material destructions by working members of the crushers. Thus, the authors have developed the crushing theory as an original solution of a complex constructively nonlinear engineering and technical problem on the static contact of a spherical model of a comminuted brittle substance with absolutely rigid convex-concave surfaces of cylindrical rolls designed for coarse and medium grinding. The theory is based on the classical assumptions of the mechanics of an elastically deformable continuous medium, the fundamental analytical dependences of Hertz-Shtaerman and the Kirpichev-Kick volumetric energy hypothesis. During the quantitative assessment of the bearing capacity of the ball, we used the well-known physical and mathematical problem of Weber on the stress state of a sphere loaded by two equal forces applied at the poles, and the Kulon-Mor’s strength criterion, which describes the process of destruction of a wide class of brittle homogeneous materials. The developed theory of fragmentation has been brought to the design formulas and illustrated with a typical numerical example.

A mathematical model of reconstruction of the fields of residual stresses and plastic deformations in thin-walled cylindrical tubes in the delivery state and after bilateral surface plastic hardening was developed. It included a method for identification of the model parameters using the example of thin-walled mm tubes made of X18N10T steel based on experimental data for the axial and circumferential components of the residual stress tensor for samples in the delivery state and after bilateral mechanical ultrasonic hardening. The adequacy of the mathematical model for the reconstruction of residual stresses in the thin-walled tubes made of X18N10T steel was verified by the experimental data in the state of delivery and after bilateral surface plastic hardening, taking into account the anisotropy of the distribution of plastic deformation after hardening in the axial and circumferential directions. A method for calculating the two-way relaxation of residual stresses on the outer and inner surfaces of thin-walled tubes under creep conditions was developed based on the generalization of the corresponding method for unilateral hardening. The relaxation process in the thin-walled tubes made of 08X18N9 steel (an early analogue of X18N10T steel) under conditions of thermal exposure, axial tension, internal pressure and the combined action of axial tension and internal pressure was investigated on the basis of the constructed phenomenological creep theory for this steel. A detailed analysis of the kinetics of the fields of residual stresses during creep in the thin-walled samples in the delivery state and after bilateral hardening at different times was performed. It is shown that under these conditions, almost a complete relaxation of residual technological stresses occurs both in the samples in the delivery state and after bilateral surface plastic deformation within 50 hours.
