Teaching Geometry Using an Adapted Narrative: A Case Study with a Visually Impaired Student
Authors: Borges Fabio , De Carvalho Rutz da Silva Sani , Midori Shimazaki Elsa , Mamcasz Viginheski Lúcia Virginia
Published: January 2023

Context: Inclusive education for disabled people is an ongoing debate within schools, making it necessary for teachers and institutions to create methodological pathways that ensure an equitable and effective learning process for all pupils, regardless of their limitations. Objectives: To investigate the contributions of a tactile adapted version of the historical narrative “Eratosthenes and the Circumference of the Earth” in the formation of geometry concepts in visually impaired students and the challenges associated with the teaching process, this proposal is based on the application of an adapted didactic structure through Eratosthenes’ historical narrative, focusing on teaching the similarity of triangles and geometry. The study was based on Vygotsky’s cultural-historical theory and Galperin’s theory of the gradual formation of mental actions. Design:  The methods are qualitative in nature via a case-study strategy. Environment and participants: The research was conducted with a class of 46 students, of which one is visually impaired, attending the first grade of high school at a public institution in the countryside of Paraná-Brazil. Data collection and analysis: Data were collected through activities performed in class and an evaluation questionnaire. Data were analysed through content analysis. Results: The results show that the intervention contributed to the assimilation of mathematical concepts by the visually impaired individual and other students, showing changes in the perceptions of key topics within plane geometry, previously demonstrated by the students as partial and non-scientific concepts. Conclusions: We can emphasise the need for research and studies targeting the construction of proposals and materials that enable an equitable and inclusive teaching process for all students.
Reverse Mathematical Modelling
Authors: Sodré Gleison De Jesus Marinho , Ferreira Raquel Soares do Rêgo , Guerra Renato Borges
Published: January 2023

Background: Research in mathematics education shows that mathematical modelling is a practice that seeks to “translate” problem situations into possible mathematical models without, however, explaining the complexity involved in the reverse formulation, starting from the mathematical model to delimit the type of situation. Objective: To highlight the problem of reverse mathematical modelling, in the sense of a reverse formulation that goes from the mathematical model to the situation. Design: For this, a course of study and research was carried out guided by the investigative cycle of mathematical modelling that is based on theoretical-methodological resources of the anthropological theory of the didactic. Setting and Participants: Pre-service teachers of a teaching degree at a public institution were faced with a problem in an unusual context about the decimal number system and, more broadly, the positional number system. Data collection and analysis: We present an empirical approach based on research carried out by Ferreira (2020) with teachers in initial training. Results: The empirical results observed confirm the hypothesis of the existence of the problem of reverse mathematical modelling, even in the face of normative models, in the sense that they can faithfully describe a real situation. Conclusions: Ultimately, the study of a type of problem in an unusual context, in addition to highlighting the encounter of teachers with different objects of knowledge, revealed the remarkable difficulty in delimiting the type of quantification situation that can be associated with the mathematical model of the number and as stimulate future research on the teaching of reverse mathematical modelling.

Post-quantum cryptographic algorithm identification using machine learning
Authors: Rocha Bruno Santos , Xexeo Jose Antonio Moreira , Torres Renato Hidaka
Published: January 2023

This research presents a study on the identification of post-quantum cryptography algorithms through machine learning techniques. Plain text files were encoded by four post-quantum algorithms, participating in NIST's post-quantum cryptography standardization contest, in ECB mode. The resulting cryptograms were submitted to the NIST Statistical Test Suite to enable the creation of metadata files. These files provide information for six data mining algorithms to identify the cryptographic algorithm used for encryption. Identification performance was evaluated in samples of different sizes. The successful identification of each machine learning algorithm is higher than a probabilistic bid, with hit rates ranging between 73 and 100%.

Authors:   Baden-Wuerttemberg Cooperative State University, Mannheim, Germany, Schäfer C. , Siegfried P. ,   International School of Management GmbH, Frankfurt, Germany
Published: January 2023

Der Automobilhandel befindet sich in einer momentanen Phase des Umbruchs. Der Trend zum Kauferlebnis online, verstärkt durch die Pandemie, und die durch die Dieselproblematik entfachte Diskussion zum Emissionsausstoß und Fahrverboten für Verbrennungsmotoren im Fahrzeugbereich, treibt den Wandel zu elektrischen Antriebstechnologien an [1]. Durch diese Umstellung ergeben sich neue Möglichkeiten für das Fahrzeug im Bereich der Digitalisierung [2]. Die branchenübergreifende Digitalisierung findet sich auch in den neuen Vertriebssystemen der Automobilhersteller wieder [3]. Hierbei ist zudem eine Veränderung der Absatzkanäle zu beobachten. Der Kunde weicht beim Autokauf davon ab, exklusiv zu dem Händler seines Vertrauens zu gehen und sich hier durch den gesamten Verkaufsprozess hinweg betreuen zu lassen. Vielmehr verschieben sich einzelne Teilbereiche in das Internet. So müssen etablierte Prozesse neugestaltet werden, um weiterhin im Markt und im Wettbewerb bestehen zu können. Das Ziel dieser Arbeit ist die Beantwortung zweier Forschungsfragen. Zum einen soll der Status-Quo der Digitalisierung von Vertriebsinstrumenten im Autohaus untersucht werden. Konkret geht es dabei um die Frage, in welcher Art und Weise die Digitalisierung den Vertrieb beeinflusst und welche Effekte sich daraus ergeben. Zum anderen stellt sich die Frage wie die Digitalisierung in Form des Internets, als Absatzkanal für die Automobilindustrie geeignet ist, und ob derart komplexe Produkte wie ein Neufahrzeug über diesen Kanal abgesetzt werden können. Weiterhin soll betrachtet werden, welche Veränderungen in den Vertriebsstrukturen das beim stationären Autohändler verursacht. Die Arbeit befasst sich ausschließlich mit der Digitalisierung bei Vertragshändlern mit Volumenzielen im Neuwagen-Bereich. Damit sind die Luxus- oder Premiummarken ausgeschlossen. Außerdem wird im Autohaus in zwei Kundenkategorien unterschieden. Es gibt die Großabnehmer und die Einzelkunden. Die Großabnehmer sind Unternehmen, die durch eine vordefinierte Anzahl an Mindestabnahmen einen besonderen Status und Konditionen genießen. Die Einzelkunden sind private Abnehmer oder gewerbliche Kunden, die die Mindestabnahme nicht erreichen. Die Arbeit beschränkt sich ausschließlich auf die Analyse und Auswirkungen der Veränderungen im Segment der Einzelkunden.
Palaeoproterozoic structural evolution of polyphase migmatites in Olkiluoto, SW Finland

Published: January 2023

In migmatitic environments the behaviour of the system is controlled by the generation and amount of the anatectic melt. Accordingly, migmatites typically show a genetic linkage between the tectonic deformation and melt migration. We investigated this relationship in Olkiluoto (SW Finland) and identified four phases of ductile deformation, which are distinguished by the multiple folding phases, ductile shear events and cross-cutting features associated with pegmatitic leucosomes and/or a specific type of diatexitic migmatite with feldspar megacrysts. U–Pb LA-MC-ICPMS data on zircon cores and rims from migmatites and cross-cutting pegmatites indicate two distinct metamorphic events associated with melt generation and migration at 1.87–1.84 Ga and 1.82–1.78 Ga. These two migmatitic events suggest that the orogenic evolution of the area was long-lasting and characterized by slow cooling. The structural data and the age constraints presented in this paper support the idea of similar tectonic evolution and metamorphic environment in SW Finland and central E Sweden.
Hiekkapohja hydrothermal system – ore mineral, lithogeochemical and paleomagnetic evidence from the Paleoproterozoic Central Finland Granitoid Complex

Published: January 2023

The Paleoproterozoic Svecofennian Central Finland Granitoid Complex (CFGC) has been regarded as an area of low mineralisation potential. The Hiekkapohja area, 20km north-east of the town of Jyväskylä, host a concentration of variable metalliferous showings. Samples from mineralised boulders and outcrops display variable combinations of anomalously high concentrations of Cu, Mo, Zn, Pb, W, Pb, Ag, As, and Au. The area is composed mainly of peraluminous and ferroan granitoids. The dominant porphyritic Hiekkapohja granodiorite (~1.88 Ga) is cross-cut by the equigranular Soimavuori granite of similar age. The porphyritic Lehesvuori granite on the western side of the study area represents marginally older (~1.89 Ga) magmatism. The paragenetic sequence of the ore minerals shows that the Hiekkapohja area has been affected by at least two separate stages of hydrothermal activity. The first mineralisation stage was widespread, crystallising typically chalcopyrite, pyrrhotite, sphalerite, galena, arsenopyrite, magnetite and Ag-bearing minerals. After the first stage, a low temperature oxidising phase formed hematite and marcasite. The second mineralisation stage enclosed low temperature minerals, such as marcasite and native Ag and Ag-minerals, as inclusions inside chalcopyrite, pyrite, pyrrhotite, sphalerite, and arsenopyrite. The mineralised samples typically display signs of K-metasomatism and less commonly signs of propylitic alteration. During the second mineralisation stage the fluid flow was controlled by the dominant 120°–135° trending shear zones. Both the hydrothermal activity and the regional geology indicate that porphyry type ore forming processes have occurred in the Hiekkapohja area. Paleoproterozoic resetting of the remanent magnetisation is further evidence for the role of the hydrothermal system.
Examining Global Wellness, Anxiety Severity, and Depression Severity Among Black and Latinx Adults: Implications for Counseling
Authors: Kalkbrenner Michael T.
Published: January 2023

The effectiveness of the Global Wellness scale of the Lifestyle Practices and Health Consciousness Inventory, measuring combined mental and physical health, is well documented in the literature among samples of primarily White clients. However, the global wellness literature is lacking research among ethnic minority populations who tend to face healthcare inequities. For example, Black and Latinx adults in the United States face inequities in the quality and accessibility of mental and physical healthcare services, including unique risks for anxiety and depression. In this study, a national random sample (N = 4,009) was recruited (stratified by age, gender, and geographic region of the United States) of Latinx and Black adults to examine the association of anxiety severity and depression severity with global wellness as well as demographic differences in global wellness. Anxiety and depression emerged as significant negative predictors of global wellness, and results revealed a number of demographic differences in global wellness. Implications for counseling practice and how mental health counselors can reduce healthcare disparities are discussed.

Abstract: It is known that since the early 2000s there has been a rapid increase in data traffic and a significant increase in the need for information flows in the process of providing new types of telecommunications services. This has led to the fact that the existing telecommunications networks have failed or approached the limit of their ability to serve subscribers with specified quality of service. The problem of improving the network architecture of such networks and improving the quality of their operation based on the use of modern methods and principles has arisen and needs constant solution. In this paper the requirements to the bandwidth of the channels of the telecommunication network management system in modern conditions are analyzed and their formalized description is given. In order to assess the bandwidth of the channel of the control network of the telecommunications network on the indicators of the quality of its work in the transmission of various types of data in the work developed and submitted an appropriate methodology. The method is based on mathematical dependences that describe the process of functioning of the telecommunication network management system based on the application of the laws and rules of queuing theory.
Modelling Multilayer Communication Channel in Terahertz Band for Medical Applications
Authors: Mahmoud Essraa Hesham , Gadelrab Mohammed S. , ElSayed Khaled , Sallam Abdel Rahman
Published: January 2023

In this work we present a multi-layer channel model for terahertz communication that incorporates both layers of human body tissues and textile layers. Many research works tackled communication channel modelling in human body alone while some other research focused on textile characterization/modelling alone. There is a real gap in connecting these different models. To investigate this, a multi-layer channel model for terahertz communication is developed, this model assumes external textile layer stacked over layers of human body tissues. The electromagnetic properties of the different layers are extracted from previous works that used time domain spectroscopy (TDS) in the terahertz band to characterize each of the considered layers. The model is implemented as a flexible MATLAB/Octave program that enables the simulation of layers with either fixed or random depths. This paper aims to pave the way to connecting patients’ in-body nano-nodes with off-body (on-cloth) nano-nodes by building such a combined channel model. This helps in many applications especially in the medical field. For example, having connected nano-nodes can help in diagnosing diseases, monitoring health by sending information to the external environment, treatment (e.g., increasing or decreasing a certain dose depending on the monitoring), etc. The obtained results show how the THz signal can be affected when it propagates through heterogeneous mediums (i.e., human body tissues and textile). Various types of path-loss has been calculated for this purpose and verified by comparison with results from previous research on separate models of human body and textile.
Low-level laser therapy in the supportive treatment of dermatologic adverse events in oncology
Authors: Polonskaia Aleksandra S. , Shatokhina Evgeniya  A. , Kruglova Larisa S.
Published: January 2023

Supportive treatment plays an important role in oncology nowadays. The main aims of oncologic supportive treatment are management of cancer symptoms and adverse events of cancer treatment.
In terms of dermatologic adverse events the most important types of reaction are oral mucositis during radiation therapy, chemotherapy and during hematopoetic stem cell transplantation, palmoplantar syndrome during chemotherapy, palmoplantar skin reaction, acneiform paronychia and pyogenic granulomas during targeted therapy, immune-related dermatologic adverse events during immunotherapy.
During recent years, special attention has been paid to low level laser therapy for the prophylaxis and management of cancer therapy dermatologic adverse events. The effects of low level laser therapy may have a beneficial effect on many conditions that play important roles in the pathogenesis of radiation and chemotherapy-induced complications in oncologic patients. Therapeutic effects of low level laser therapy are attributed to the stimulation of adaptive processes and to the increase of nonspecific resistance. The latter develop due to the close interaction of the immune, humoral and nervous systems. When choosing a method for the supportive treatment of cancer therapy adverse events, it is extremely important to establish safety in terms of the tumor process and absence of negative effects on cancer treatment.
Effects of low level laser therapy on the proliferative and invasive activity of an existing malignancy remains a matter of debate due to conflicting results from in vitro studies.
At the same time, according to the results of numerous clinical studies, the use of this method is assumed to be safe for cancer patients.
Efficacy of transcutaneous electrical nerve stimulation in the treatment of a patient with amyotrophic lateral sclerosis due to syringomyelia
Authors: Al-Zamil Mustafa Kh. , Kulikova Natalia G. , Vasilieva Ekaterina S.
Published: January 2023

This paper demonstrates a clinical case of the development of amyotrophic lateral sclerosis with lesions of the anterior horns of the spinal cord in the cervicothoracic region against the background of syringomyelia.
The main complaints of the patient at the initial request for medical care were associated with weakness and hypotrophy of the right hand. Electrokymography revealed signs of damage to the anterior horns of the spinal cord at the C5Th1 level with a predominant lesion of the motor fibers of the right median and ulnar nerves. As a result, a diagnosis of amyotrophic lateral sclerosis was made. Magnetic resonance imaging revealed the presence of Chiari I malformation and severe syringomyelia of the cervical and thoracic calving of the spinal cord.
The patient underwent surgical posterior decompression of the foramen magnum. However, the treatment was not effective with the worsening of the neurological deficit in the right hand and the spread of motor deficit and hypotrophy to the left hand.
After the use of transcutaneous electrical neurostimulation of the median and ulnar nerves, there was a significant regression of motor deficit with a decrease in the severity of malnutrition without significant changes in the electromyography parameters of the median and ulnar nerves.
The absence of neurological deficit in the lower extremities, with the preservation of tendon reflexes in the norm, and the absence of pathological reflexes, indicates a high plasticity of the pyramidal tracts at the level of the spinal cord.
Regression of motor deficit after the use of transcutaneous electrical nerve stimulation is due to improvement in the state of altered motor units with hypertrophy of muscle fibers and acceleration of reinnervation processes.
Effects of a combination of herbal oils (rosemary, black cumin, and clove) on quail growth, antioxidant enzymes and health status
Authors: Al-Ghamdi Etab Saleh
Published: January 2023

The purpose of this trial was to evaluate the potential of herbal oil combinations (rosemary, clove, and black cumin) in quail feeding as a natural growth enhancer. The effects of dietary gradual levels of this blend (RCBC) on growth indices, carcass attributes, and blood biochemical variables were compared to the control group (basal diets). For this, 300 1-week-old developing quails were employed. Birds were kept on the baseline diet with or free of herbal oils blend (RCBC) at three different amounts (0, 1.50, and 3.00 cm3/kg diet) from one to six weeks of age to suit their nutritional needs. There were no variations in live body weight or body weight gain over the entire period or at intervals. Compared to the control, birds fed RCBC-supplemented diets devoured more feed (P<0.01). RCBC supplementation in the diet did not affect the feed conversion ratio. Except for heart %, all carcass features were statistically (P <0.01) different after RCBC treatment when compared to the control. The amounts of total globulins, total protein, and albumin in quails given RCBC were higher than the control (P<0.001). In quails, the hepatic levels of GSH and the activity of SOD, catalase, GR, GPx, and GST all increased (P<0.001). MDA concentrations in hepatic homogenate were dramatically reduced by RCBC diets. Finally, RCBC supplementation at a dose of up to 3.0 cm3/ kg diet is recommended to enhance the growth and general health of quails during growth, which would have a favorable impact on the general health of quail meat consumers.

Published: January 2023

Aim    To analyze long-term outcomes by results of the prospective part of the Kuban registry of patients with an implantable cardioverter defibrillator (ICD).Material and methods    A prospective analysis of the incidence of hard endpoints and changes in the condition was performed for 260 patients with ICD successively added to the Registry of Patients with Implantable Cardioverter Defibrillator” from 2015 through 2019.Results    At the time of ICD implantation, all patients had chronic heart failure (CHF), mostly of ischemic etiology with a low left ventricular ejection fraction (LVEF); median LVEF was 30 (25; 36.5) %. 54 of 266 (21.9 %) patients died by 2021;  17 of them (31.5 %) died in the hospital; in 76.5 % of cases, death was caused by acute decompensated heart failure (HF). 139 (53.5%) patients were readmitted; 66 (25.4 %) hospitalizations were related with ICDs (lead revision or reimplantation); acute cardiovascular events developed in 38 (14.6 %) patients; 12 (4.6%) patients underwent percutaneous coronary interventions; orthotopic heart transplantation was performed for 4 patients. ICD shocks were recorded in 27 (10.4 %) patients. After the ICD implantation, median LVEF remained unchanged, 31 (25; 42) vs. 30 (25; 36.5) % (р>0.05). However, both objective and subjective HF symptoms worsened. Thus, the number of patients with IIB stage CHF increased from 29.6  to 88.8 % (р<0.01) and with NYHA III CHF from 24.2  to 34.5 % (p<0.05). 80 (30.8%) patients visited cardiologists on a regular basis. Only 7.3% of patients received an optimal drug therapy. During the observation period, the rate of beta-blocker treatment considerably decreased, from 90.6  to 64.3 % (р<0.01), and the rate of the mineralocorticoid receptor antagonist treatment decreased from 50.8  to 17.4 % (р<0.01). The rate of the diuretic treatment was inconsistent with the severity of patients’ condition.Conclusion    Most of the problems the patients encountered after the ICD implantation were related with an inadequate treatment of the underlying disease. Since the majority of patients with ICD have a low LVEF, it is essential to focus on prescribing an optimal drug therapy and maintaining compliance with this therapy.
Рossibility of using European (HFA-PEFF) and American (H2FPEF) algorithms for diagnosing heart failure with preserved ejection fraction in Russian clinical practice
Authors: Ageev F. T. , Yarovaya E. B. , Ovchinnikov A. G.
Published: January 2023

This article focuses on the significance of a unified approach to diagnosing heart failure with preserved left ventricular ejection fraction (HFpEF). The key hemodynamic index of HFpEF is increased left ventricular filling pressure (LVFP) and its noninvasive marker, the E / e’ value obtained by tissue Doppler echocardiography (EchoCG). The modern verified algorithms for HFpEF diagnosis, HFA–PEFF and Н2FPEF, mandatorily take into account the E / e’ value. However, the routing use of these algorithms in the Russian practice may be complicated since even among “advanced” specialists who are interested in heart failure, 38% of the interviewed do not use or do not know how to use tissue Doppler EchoCG or the algorithm for diagnosing HFpEF with E / e’. In addition to the obvious way of overcoming this problem by equipping respective medical facilities with ultrasonic apparatuses with tissue Doppler EchoCG software and educating physicians, a possibility of using simplified HFA algorithm without the E / e’ value is being considered. However, such approach will inevitably lead to erroneous estimation of the probability of HFpEF and, at the best, to underestimation of this probability with ensuing mistakes in diagnosis and treatment. Simplifying the HFA–PEFF and H2FPEF algorithms by omitting one or more parameters is possible but this requires a special investigation to develop a new rating scale and actually a new algorithm, which, in turn, will require a new validation.
Greenland in U.S. Arctic Strategy: A Challenge for Danish-American Relations?
Authors: Belukhin Nikita
Published: January 2023

At the present moment there is an increasingly palpable desire on the part of Greenland's autonomous government to move to bilateralism in its relations with the United States, leaving Denmark out of the equation, and to expand its own diplomatic presence and powers. Since Greenland does not support militarization, it would be optimal for Denmark and the United States to expand technical "domain awareness" capabilities in the High North. The economic dimension presents the U.S. with the difficult task of supporting the creation of an efficient mining industry in Greenland, which, however, could potentially contradict the environmental priorities of the current Greenlandic government.

Published: January 2023

Numerous studies examine the electrical and mechanical, internal and exterior problems of induction motors separately. However, this type of machines is also susceptible to several combined faults which affect it at the same time. The aim of this work is to study firstly the effects of the mass imbalance with the supply voltage unbalance faults in a combined state, and specifically its effects on the stator currents (distortion of currents waveform and augmentation of current unbalance factor (CUF)). The findings of this research were derived from experimental tests, which enabled us to produce the combined voltage and mass imbalance fault intentionally. The second purpose of this paper is to identify these irregularities. In the field of induction motor fault diagnosis, the stator current analysis techniques have shown to be quite successful and have gained widespread use. Therefore, we used the well-known method motor current signature analysis (MCSA). In addition, we have strengthened the research by using spectral analysis on the Park's components (Id and Iq). The obtained results demonstrate the efficacy of analyzing stator currents and Park components spectra (particularly the direct Park component (Id)) for detecting this kind of electrical and mechanical combined defects

In recent years, MOOCs (Massive Open Online Courses) have become popular and the online learning resources are increasing, they are an offered courses by schools and universities, which are accessible to everyone and free of charge on the internet, they offer the possibility to teach a very group of students, in the same course, at the same time, even if they are not in the same location. There are many MOOCs platforms with different characteristics, they contain a huge amount of data, so the learner does not know which course to take and can choose irrelevant MOOCs. Therefore, he will waste the time and also the motivation. Recommender systems give a solution to this problem, they suggest learning resources to learners according to their interests and needs, so learner will be satisfied because he finds an appropriate course. In this paper, we give a systematic literature review of MOOCs recommender systems, based on published papers in the past ten years, between 2012 and 2022. We have selected 123 papers from five databases, IEEE Xplore, Springer Link, Science Direct, Google Scholar and ACM Library. We have divided the data analysis in two parts, the quantitative analysis, and the qualitative analysis. In the quantitative analysis, we have studied first the evolution of papers by year and the distribution of papers on databases by type. Then, in the qualitative analysis, we have based principally on the distribution of papers by the existed areas in MOOCs. We have found that there are six main fields, course recommendation, peer recommender, MOOC provider, video recommendation, learning activities and OER, paid activities recommender system and other papers in various types. A high number of articles have been published in the field of courses, which confirms that this domain is very important and crucial for learners.
Determinants of Tuition Prices in Private Universities of Mexico: A Panel Data Analysis at the State Level 2005-2019
Authors: Flores Miguel , Salcedo Alejandrina , Torre Leonardo
Published: January 2023

Objective: Estimate a supply and demand model of private college education services in Mexico for the 2005-2019 period, in order to identify the factors that influenced the dynamics of their equilibrium prices.Methodology: The methodology consists of estimating such models with two- and three-stage least squares using panel data at the state level.Results: The results suggest that while the contribution of demand variables to the inflation of such prices has been positive and fairly stable, that of supply variables, even though it has been more fluctuating, it has also been larger than the contribution of the former throughout the entireperiod.Limitations and implications: It bounds the discussion on the role associated with private universities own characteristics as well as market structure due to lack of disaggregated information at private institution level.
Originality and value: This paper contributes to the literature on the subject in Mexico by providing the first estimates of supply and demand elasticities for private higher education.
Conclusions: Based on these estimates, it was possible to identify the dynamics of the equilibrium prices of tuition fees at private universities in Mexico and their relationship with both supply and demand factors.
Does high-intensity laser therapy speed return to primary function in horses with suspensory ligament desmopathy?
Authors: Rushing James
Published: January 2023

PICO question
In horses with a suspensory ligament branch injury, does high-intensity laser therapy (energy output greater than 500 mW) combined with conservative management, compared to conservative management alone, result in a faster return to primary function?
 
Clinical bottom line
Category research
Treatment.
Number and type of study deisgns reviewed
The number and type of study designs that were critically appraised were two peer-reviewed studies: a non-randomised controlled clinical trial and a randomised controlled experimental study.
Strength of evidence
Weak.
Outcomes reported
The outcomes reported are summarised as follows: the two appraised studies report positive effects of high-intensity laser therapy (HILT) on equine tendon and ligament injuries as measured by pain to palpation, lameness, swelling and ultrasonographic and magnetic resonance imaging (MRI) evaluation of HILT-treated lesions.
Conclusion
In view of the strength of evidence and the outcomes from the studies the following conclusion is made: the two appraised studies provide only weak evidence to show that horses treated with high-intensity laser therapy (HILT) and conservative management return to primary function sooner than horses treated with conservative management alone. Issues of design, methodology, statistical analysis and reporting reduce the reliability and external validity of these studies.
 
How to apply this evidence in practice
The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources.

La traza del Vocabulario de mexicanismos de Joaquín García Icazbalceta: Estudio lexicográfico e historiográfico
Authors: Zamudio Mesa Celia , Cifuentes Bárbara
Published: January 2023

El presente estudio analiza el Vocabulario de mexicanismos de Joaquín García Icazbalceta a la luz de las ideas planteadas por él mismo en el documento Provincialismos mexicanos, publicado como Prólogo del Vocabulario. Postulamos dos tesis que guiarían al autor en la consecución de su obra lexicográfica. La primera refiere a la naturaleza de los “provincialismos mexicanos”, a los que García Icazbalceta atribuye un origen prominentemente hispánico. La segunda puntualiza su concepción del español americano, su valor en cuanto expresión propia y legítima de los hispanohablantes de esta parte del mundo y, por consiguiente, la necesidad de documentar tanto su presente como su pasado.

Nuestro propósito es mostrar cómo García Icazbalceta materializó ambas tesis en la macroestructura del Vocabulario y, simultáneamente, destacar el carácter descriptivo de su diccionario y su valor historiográfico. En el análisis intentamos determinar, en la medida de lo posible, los criterios de selección léxica empleados por el autor; después, hacemos un recuento de todos los vocablos incluidos, las clasificaciones y marcación que les dio, la data que hizo de sus autoridades y su constatación en cuanto americanismos. Por último, presentamos una caracterización de la microestructura de los artículos en la que se evidencia el método seguido por el autor para desarrollarlos.
Valores epistémicos de igual e igual y en datos del español de México
Authors: Frías Castillo Adán
Published: January 2023

En el presente artículo se analizaron los valores modales del adverbio igual en el español mexicano, cuya configuración no ha sido descrita en esta variante. Se encontraron casos donde el adverbio precede a la conjunción y formando la locución adverbial igual y la cual aparece también en contextos modales. Este trabajo busca comparar los diferentes matices semánticos de las dos construcciones en el español mexicano. Para cumplir tal objetivo, se analizaron casos de muestras orales extraídos del Corpus Sociolingüístico de la Ciudad de México y de PRESEEA. Los resultados muestran valores epistémicos de posibilidad, atenuación, expectativa e hipótesis en ambas marcas modales. El marcador modal igual y se encuentra en más del doble de casos en relación con igual, lo cual responde a la facilidad de y no coordinado para incorporarse a contextos epistémicos. Como consecuencia, igual y presenta un espectro más amplio de usos y más libertad sintáctica.
Las estrategias comunicativas de a en español a la luz de una nueva propuesta de significado
Authors: Risco Roxana
Published: January 2023

Las gramáticas tradicionales y los tratados prescriptivos ofrecen listas de usos preposicionales de a, que bien podemos considerar listas de tipos de mensajes (Alcina Franch y Blecua, 1979; Alonso y Henríquez Ureña, 1981[1938]; Cifuentes, 1996; Fernández López, 1999; García Yebra, 1998; RAE-ASALE, 2010; López, 1970; Luque, 1973; Náñez Fernández, 1990; entre otros). Las listas suman más de veinte entradas diferentes y muestran la medida del desafío que supone el estudio de su significado. En ese sentido, el presente trabajo tiene por objetivo proponer un nuevo significado para a, en línea con la perspectiva teórica de la Escuela Lingüística de Columbia (Diver, 1995 [2012]; Huffman, 2001, 2006; Huffman y Davis, 2012; Otheguy, 1995, 2002, 2018; Reid, 1995, 2018; Stern, 2019), un enfoque que guarda similitudes con el campo de la lingüística cognitiva y la lingüística basada en el uso (Harder, 1996; Langacker, 2004; Bybee, 2010; Croft, 2013). Para ejemplificar la explotación del significado postulado para a, nuestra indagación presenta y analiza la observación de contextos de uso en un corpus formado por instancias de cerca a, en alternancia con cerca de, en hablantes que explotan este contraste para producir sutiles diferencias en sus mensajes.
Mobile Commoning: Reclaiming Indigenous, Caribbean, Maroon, and Migrant Commons
Authors: Sheller Mimi
Published: January 2023

Over the last two decades, the concept of ‘the commons’ has been rediscovered as a powerful organizing principle in social movements, radical political thought, and critical theory. The concept of commoning has also been adopted within discussions of migration and critical mobilities research. This article will first trace some of these emerging ideas of commoning as a relational practice found in many political mobilizations around ‘reclaiming the commons’. Then it will turn to approaches to commoning that seek to complicate Euro-American histories by centering Indigenous practices of radical commoning, Caribbean and African diaspora mobile commoning, and recent concepts such as undercommons, queer commons, and migrant mobile commoning. The article asks: How can such practices of radical mobile commoning help us envision ways to unmake the existing violent settlings and destructive im/mobilities of enclosure, coloniality, imperialism, and capitalist extraction?
