Looking into today’s mechanism synthesis we see that this well-developed field has been studied from many perspectives such as; transmission angle, working envelop, Grashof criteria and many others. Also, many mathematical representations were used to solve the problems in this field such as vectorial methods, exponent methods dimensionless analysis, genetic algorithm, artificial intelligence. This paper will be presenting new mathematical approach to solve the mechanism synthesis using motion generation function. This proposed method will study how far the proposed mathematical model (i.e. matrix inversion) will ensure the mechanism to go through prescribed poses or try to approximate them with tolerable error.
Review on Wearable Antennas and their Applications
Authors: Christina G.
Published: May 2022

Wearable antennas are one of the primary sources for the Body Area Networks (BAN). It allows the users to sense, communicate, transfer and exchange data to a remote server with the help of IoT gateway. The size, speed, and power consumption play a major role in the design of wearable antennas. In most of the applications, the wearable antennas are connected over the cloth of the user and in rare cases the antenna is fixed over or under the skin of the user. The motive of this paper is to review the technologies behind the design of wearable antennas and their applications in various fields. Moreover, the paper determines the research gap in the field of wearable antenna designing.
Effect of Steel and Prestressed GFRP Bars on Bending and Shearing Failure Modes in Reinforced Beams
Authors: Najaf Erfan
Published: May 2022

In recent years, there has been significant progress in using FRP materials as masonry in civil engineering. In this regard, researchers have investigated the behavior of reinforced beams with FRP and steel bars. One way to enhance these sections is to prestress FRP bars to increase sections' bending and shearing strength. Reinforcing with a hybrid bar is a new method in which GFRP and steel bars are combined. In this research, the type of GFRP bars is first determined, and then samples are prestressed. Samples are modeled using LS-DYNA software. Bending and shearing failure modes of reinforced beams with FRP, GFRP, steel, and hybrid bars are analyzed, and finally, load-displacement behavior and crack width are compared. By studying the beam's bending and shearing behavior and failure modes, we found out that using hybrid bars decreases the number of cracks Wider than 0.35 mm in the same displacement and greater loading capacity. By comparing load-displacement diagrams of samples, we conclude that the sample reinforced with hybrid bars has the best function. We can benefit from the anti-corrosion property of GFRP bars by arranging the reinforcements properly. The loading capacity of the sample can be increased by about 65% by prestressing them. Consequently, the displacement of samples decreased.

Authors: ALKAÇ Erkan , CEYLAN Fahrettin
Published: May 2022

Amphorae are stamped by production centers, especially in the Aegean Region. Stamps, which are epigraphic evidence, provide the date of the layer or context they were found by determining the origin of the amphorae and reveals the commercial relations between the production and consumption centers. There are many amphorae in the Edirne Museum of Archaeology and Ethnography. These amphorae are recorded in various ways in the inventory of the museum. It was determined that only five of the amphorae in the museum collection were stamped. This article aims to classify the stamped amphorae according to their production centers, to give a date to the stamped amphorae and to analyze the inscriptions on the stamps.In this study, seven stamps on five amphorae with preserved double handles were examined. Three of these stamps are Thasos and four are Rhodes. Only two of the Rhodesian stamps have been resolved. As a result of our investigations, it was determined that these stamped amphorae belonged to Thasos and Rhodes. The stamps have the names of the eponym and the producer, ethnicon and symbol. The date of the stamps that can be read within the scope of this article is determined by the names of the eponyms and producers. It is understood that the stamped amphorae here are generally from between the 4th – 2nd centuries BCE.
ERGONOMIC ASPECTS OF LABOR PROTECTION IN AGRICULTURE
Authors: Spirin Anatoly , Tsurkan Oleh , Tverdokhlib Igor , Borysiuk Dmytro
Published: May 2022

One of the reasons for the high level of occupational injuries and diseases in Ukraine is the lack of attention to compliance with ergonomic requirements for facilities and working conditions. Ergonomics is an element of a complex system of "labor protection" which is connected by intra-system connections with other elements of this system. In turn, ergonomics is a system for a number of relevant elements, the main of which are man and means of labor. The main task of labor protection (and, of course, ergonomics) is to ensure healthy and safe working conditions that minimize cases of occupational injuries and diseases. Research of human-machine systems is conducted in many directions with the use of modern methods. But we must also recognize that there are still many problems in this area of human life. This is eloquently evidenced by the statistics of occupational injuries (including fatal) in agriculture of Ukraine.
The aim of the research is to reduce the number of occupational injuries and occupational diseases of agricultural workers by studying the ergonomic principles of the human-machine system, identifying its basic elements, relationships, possible reactions to external and internal disturbances and developing adequate solutions to reduce possible risks to the life and health of workers.
The relationship between man and machine is one of the many types of relationships that work. There are four types of such dependencies: "man-machine", "man-man", "machine-machine", "operation-operation". In ergonomic research, it is often important to determine how a worker uses the controls in his workplace - how often he uses each of these organs and, most importantly, in what sequence.
In order to facilitate the solution of this problem, the concept of "communication" is introduced. Information about the obtained connections is summarized with the help of special matrices.
In addition to the interaction of man and machine in agriculture, it is necessary to take into account the specifics of the material environment and external conditions in the workplace.
The analysis of the "man-machine" system should include not only technical aspects, but also take into account the specifics of the material environment and external conditions in the workplace, as well as organizational aspects that are revealed only in dynamic analysis of the system.

Review question / Objective: P:Adult patients (age ≥ 18 years) diagnosed with stroke based on relevant clinical examination; I:Intervention group with rTMS alone or in combination with other treatments with rTMS; C:Control group received sham treatment or no rTMS; O: Upper extremity function:the Fugl-Meyer Assessment Upper Extremity (FMA-UE); Hand function:box and block test(BBT), nine-hole peg test(NHPT), and Purdue pegboard test(PPT); S:Randomized controlled trials (rather than crossover designs). Condition being studied: In Europe, more than 1 million new cases of stroke are reported each year. The absolute number of stroke patients is expected to increase in the near future due to the progressive aging of the population. Approximately 50-80% of stroke survivors present with upper extremity dysfunction. Recovery of upper extremity function is associated with improvements in activities of daily living and mental health. However, few stroke survivors show full recovery of upper extremity function 6 months after stroke. In addition, rehabilitation has a limited impact on the recovery of hand motor function.

Authors:   HSE, Rameli Puteri Maisarah , Rajendran Nithya
Published: May 2022

Review question / Objective: The proposed scoping review will address the following question: 1. What discharge initiatives or pathways are in place for older adults with complex discharge needs that encompasses all 9 domains of outcome assessment? 2. Are there follow-up studies that assess the impact or provide outcome evaluation of CDP initiatives or pathways? Condition being studied: Whilst existing literature discusses initiatives and interventions around discharge processes aimed at resolving complex needs, few have reported outcome measures to assess the efficacy of proposed interventions. With the advancement in age, there is an anticipated increase in associated multi-morbidity levels. This gives rise to poor outcomes if complex needs are unaddressed. Outcome measures such as those focusing on patient centred factors, economic factors, medication, carer outcomes, community services link in, readmission, and follow up remain underexplored. Our scoping review seeks to summarise outcomes of complex discharge planning in the older adult population and identify gaps for future research considerations.

Preliminary Model of Energy Harvesting through Prosthetics
Authors: Sachan Vyom
Published: May 2022

The goal of the paper is to harvest energy through the flexing of a piezoelectric unit in a prosthetic limb. Depending upon the flex of the sensor, it produces a voltage output. To embed this in a forearm prosthetic, a piezoelectric sensor can be attached to the hinge joint. Hence, the more it moves, the more voltage output is produced. In this paper, a prosthetic limb is modeled as a physical pendulum. The experiment done includes a voltmeter, a physical pendulum, and a piezoelectric sensor attached to the axis. Due to the formula breakdown into a 2-parameter model, the chi-squared analysis on the formula is much simpler. Hence, the author could fit the model to the data and the best fit values were found.

Uno de los grandes problemas que se observa en la enseñanza del derecho internacional público en Perú es que se parte de la premisa que esta disciplina tiene un modo homogéneo de ser  concebida. El propósito del presente artículo es deconstruir esa preconcepción a partir de dos  críticas. La primera es el cuestionamiento contra la universalidad ideológica que asume el debate  normativismo – iusnaturalismo, para dar a conocer otras posibilidades de aproximación al derecho internacional. La segunda crítica es contra la neutralidad ideológica en el estudio de nuestra  materia, con el objetivo de demostrar la presencia de un norte y un sur global en la producción  académica. Para la elaboración del presente artículo, se analizará la literatura contemporánea producida por autores peruanos y extranjeros.
ASSESSMENT OF E-TRADE IN GLOBAL ENVIRONMENT
Authors: Karazijienė Žaneta , Černikovaitė Miglė Eleonora
Published: May 2022

The article analyses the topic of e-trade assessment in a global environment. To achieve the objective, a de-tailed analysis of scientific works was carried out in order to identify the importance of e-trade assessment in a global environment and, by removing the identified limitations, to develop a model of e-trade evaluation applicable to a global environment. The empirical research was based on the developed e-trade evaluation model to test its effectiveness and applicability in a global environment. Based on the data collected, a multi-criteria assessment of e-trade was carried out, dividing the factors into five dimensions: emotional (consumer satisfaction and trust), technological (internet ac-cessibility, data security and privacy), financial (e-GDP, e-trade sales, impact of e-trade on overall company turnover), social (internet usage and purchasing volumes) and tax environment (VAT), and a comparative analysis of the coun-tries to compare the results of economically similar countries, to find out why the market leaders are performing so well in the e-trade sector, and to identify the methodologies and practices used in these countries, so as to identify the most effective methods and practices that can be applied in other countries. The results of the multi-criteria assessment al-lowed European countries to be classified into three groups: from market leaders to the most laggard countries. The strongest growth rates are found in Ro-mania and Bulgaria. It is worth noting that e-trade is also unpopular in South-ern European countries: Greece, Portugal, Spain, Italy, Malta, Cyprus.
Earth as a Proxy Exoplanet: Simulating DSCOVR/EPIC Observations Using the Earth Spectrum Simulator

Published: May 2022

Analyzing time-resolved disk-integrated spectral images of the Earth can provide a baseline for future exoplanet characterization. The Earth Polychromatic Imaging Camera (EPIC) onboard the Deep Space Climate Observatory (DSCOVR) provides ∼5000 full-disk sunlit Earth images each year in ten wavelengths from the ultraviolet to the near-infrared. A whole-disk radiative transfer model can improve our understanding of the temporal variation of Earth’s disk-integrated reflected radiance (“light curves”) at different wavelengths and create a pool of possible observations of Earth-like exoplanets. We use the two-stream-exact-single-scattering line-by-line radiative transfer model to build the Earth Spectrum Simulator (ESS) and reconstruct DSCOVR/EPIC spectral observations. Atmospheric effects, such as scattering by air molecules, clouds, aerosols, and gaseous absorption, are included. Surface contributions are treated using appropriate bidirectional reflectance distribution functions. We simulate ∼300 images in each channel for observations collected in 2016, with a spatial resolution of ∼2000 pixels over the visible disk. ESS provides a simultaneous fit to the observed light curves, with time-averaged reflectance differences typically less than 7% and root-mean-square errors less than 1%. The only exceptions are in the oxygen absorption channels, where reflectance biases can be as large as 19.55%; this is a consequence of simplified assumptions about clouds; especially their vertical placement. We also recover principal components of the spectrophotometric light curves and correlate them with atmospheric and surface features.
Coevolution of Brightest Cluster Galaxies and Their Host Clusters in IllustrisTNG

Published: May 2022

We use IllustrisTNG simulations to explore the dynamic scaling relation between massive clusters and their—central—brightest cluster galaxies (BCGs). The IllustrisTNG-300 simulation we use includes 280 massive clusters from the z = 0 snapshot with M
200 > 1014
M
⊙, enabling a robust statistical analysis. We derive the line-of-sight velocity dispersion of the stellar particles of the BCGs (σ
*,BCG), analogous to the observed BCG stellar velocity dispersion. We also compute the subhalo velocity dispersion to measure the cluster velocity dispersion (σ
cl). Both σ
*,BCG and σ
cl are proportional to the cluster halo mass, but the slopes differ slightly. Thus, like the observed relation, σ
*,BCG/σ
cl declines as a function of σ
cl, but the scatter is large. We explore the redshift evolution of the σ
*,BCG − σ
cl scaling relation for z ≲ 1 in a way that can be compared directly with observations. The scaling relation has a similar slope at high redshift, but the scatter increases because of the large scatter in σ
*,BCG. The simulations imply that high-redshift BCGs are dynamically more complex than their low-redshift counterparts.
Investigating the Disk–Jet Structure in M87 through Flux Separation in the Linear and Circular Polarization Images
Authors: Tsunetoe Yuh , Mineshige Shin , Kawashima Tomohisa , Ohsuga Ken , Akiyama Kazunori , Takahashi Hiroyuki R.
Published: May 2022

For testing different electron temperature (T
e) prescriptions in general relativistic magnetohydrodynamics (GRMHD) simulations through observations, we propose to utilize linear polarization (LP) and circular polarization (CP) images. We calculate the polarization images based on a semi-magnetically arrested disk GRMHD model for various T
e parameters, bearing M87 in mind. We find an LP–CP separation in the images of the low-T
e disk cases at 230GHz; namely, the LP flux mainly originates from downstream of the jet, and the CP flux comes from the counter-side jet, while the total intensity is maximum at the jet base. This can be understood as follows: although the LP flux is generated through synchrotron emission widely around the black hole, most of the LP flux from the jet base does not reach the observer, since it undergoes Faraday rotation (

∝

T

e

−

) when passing through the outer cold disk and is thus depolarized. Hence, only the LP flux from the downstream (not passing the cold dense plasmas) can survive. Meanwhile, the CP flux is generated from the LP flux by Faraday conversion ( ∝ T
e) in the inner hot region. Stronger CP flux is thus observed from the counter-side jet. Moreover, the LP–CP separation is more enhanced at a lower frequency, such as 86 GHz, but is rather weak at 43 GHz, since the media in the latter case is optically thick for synchrotron self-absorption so that all of the fluxes should come from the photosphere. The same is true for cases with higher mass accretion rates and/or larger inclination angles.
Two complete mitochondrial genomes of the subfamily Chloroperlinae (Plecoptera: Chloroperlidae) and their phylogenetic implications

Published: May 2022

Two new complete mitochondrial genomes (mitogenomes) of the subfamily Chloroperlinae, Haploperla japonica Kohno, 1946 and Sweltsa sp., were sequenced. The two species showed similar gene order, nucleotide composition, and codon usage. The Sweltsa sp. and H. japonica mitogenomes were typical circular DNA molecules, with lengths of 15,893 bp and 16,012 bp, respectively. Standard ATN start and TAN stop codons were present in most PCGs. All tRNA genes exhibited the cloverleaf secondary structure typical for metazoans except the tRNASer(AGN), which lacked the dihydrouridine arm. In both species, the secondary structure of lrRNA contained five structural domains, while the srRNA included three domains. The A+T-rich regions contained different repeat regions in each species. Phylogenetic analyses using Bayesian inference (BI) and maximum likelihood methods (ML) showed identical results. The family Chloroperlidae was sister to the Perlodidae. Our analyses inferred relationships between six of the seven Systellognatha families: (((Chloroperlidae + Perlodidae) + Perlidae) + (Styloperlidae + Pteronarcyidae)) + Peltoperlidae.
Dental development and first premolar homology in placental mammals
Authors: McKay Calum J. , Welbourn-Green Claudia , Seiffert Erik R. , Sallam Hesham , Li Jessica , Kakarala Sophia E. , Bennett Nigel C. , Asher Robert J.
Published: May 2022

Macroscelidid afrotherians and canid carnivorans possess four premolar loci, the first of which is not replaced. Previous work suggests that the first premolar in macroscelidids is a retained deciduous tooth, but in Canis it is a successional tooth with no milk precursor. We tested this contrasting interpretation of first premolar homology with data from ontogenetic anatomy and with area predictions from the inhibitory cascade (IC) model. Our results based on anatomy support previous interpretations that the functional first premolar is a retained deciduous tooth (dp1) with no successor in macroscelidids, and a successional tooth (p1) with no precursor in Canis. Hyracoids are among the few placental mammals that show replacement at the first premolar locus and show less deviation than other taxa of actual from predicted areas across the deciduous and molar toothrow. However, predicted vs. actual tooth areas can depart substantially from one another. At least without a better means of representing tooth size, the inhibitory cascade does not help to distinguish the deciduous from successional first premolar. This observation does not rule out the possibility that factors such as a size-shift within the toothrow (e.g., carnivoran carnassials) help to explain deviations from the inhibitory cascade model.

Published: May 2022

We present a comprehensive checklist of scleractinian (hard) corals for the Mersing Islands, Malaysia based on surveys conducted at 24 reefs across protected and unprotected marine areas. A total of 261 species of corals from 16 families and one incertae sedis (Pachyseris spp.) were recorded, along with ten records that are new for the east coast of Peninsular Malaysia. Compared against the IUCN Red List, 46.7% of coral species found in the Mersing Islands were of Least Concern (LC), 29.5% as Near Threatened (NT) and 16.4% Vulnerable (V). Only one recorded species, Pectinia maxima (Moll & Best, 1984), was listed as Endangered (EN). Baseline species diversity data are essential for the monitoring and management of marine biodiversity, especially within marine protected areas. With both protected and unprotected coral reef areas in the vicinity of the widely scattered Mersing Islands, the diversity and distribution of coral species can be used as the basis for area-based conservation and management strategies. The diversity and abundance of scleractinian corals of each island or area should be surveyed periodically to ensure the appropriate level of protection is afforded to retain scleractinian biodiversity in this region.

Quel est le rôle des États membres dans le Groupe d’experts intergouvernemental sur l’évolution du climat, organisation connue généralement pour les scientifiques de renom qui participent à ses évaluations globales des connaissances sur les changements climatiques ? En combinant les approches des études des sciences et des techniques et de la sociologie des organisations internationales, je propose tout d’abord une analyse détaillée de la manière dont les États membres du GIEC influencent les activités de l’organisation. Je montre en particulier comment cette influence se décline lors de la définition des plans des rapports et de l’approbation de leurs résumés politiques. Je reviens ensuite sur la façon dont la négociation entre auteurs et représentants des États membres façonne le texte des rapports du GIEC et sur les implications de ces pratiques sur le cadrage de la crise climatique. Ce faisant, je montre la pertinence d’une étude des groupes d’experts intergouvernementaux en tant qu’organisations internationales.

Il est d’usage de connaître la norme pour son rôle préventif. Néanmoins, plusieurs théories dénoncent la norme en tant que source immanente de risques. Cet article reprend les intuitions convergentes de six disciplines des sciences humaines et les résultats d’une recherche qualitative pour définir différentes formes du risque normatif. L’article propose une typologie de cinq risques normatifs, allant du risque de sanction à l’accroissement du risque entrepreneurial. Plusieurs facteurs sont également identifiés pour prédire la probabilité de survenance du risque normatif.
Les contraintes normatives sur le marché du bâtiment : une opportunité d’évolution des agences d’architecture vers des stratégies plus coopératives et innovantes
Authors: Ruat Thibault
Published: May 2022

Les normes sont perçues par les acteurs comme des contraintes. Pourtant, l’essence même des normes, définies par la loi française, est d’intérêt général car elles encouragent le développement économique et l’innovation dans une perspective sociétale et de développement durable. Dans cette appréhension, les normes peuvent alors constituer des opportunités stratégiques pour les organisations. Cette recherche s’est attachée à mettre en lumière comment les agences d’architecture, confrontées aux nombreuses normes du cadre bâti, peuvent transformer ce qu’elles perçoivent le plus souvent comme des contraintes normatives en opportunités stratégiques. À partir d’une étude qualitative auprès d’agences d’architecture, les résultats de cette recherche mettent en évidence qu’une implication stratégique de ces organisations dans le pilotage normatif diminue les risques liés à une insuffisante maîtrise des normes et favorise les innovations internes. La recherche apporte également des pistes de développement d’un réseau de coopération stratégique transversal visant à améliorer les performances sociétales de l’application des normes dans le bâtiment.

Limit cycle bifurcations by perturbing piecewise Hamiltonian systems with a nonregular switching line via multiple parameters
Authors: Chang Yuan , Bai Yuzhen
Published: May 2022

In this paper, we investigate limit cycle bifurcations by perturbing planar piecewise Hamiltonian systems with a switching line \begin{document}$ \left\{(x,y): y = \pm kx, k\right. $\end{document} \begin{document}$ \left.\in(0,+\infty), x\geqslant0\right\} $\end{document} via multiple parameters. With the help of Han and Xiong [3], Han and Liu [5] and Xiong [18], we obtain the second and third terms in expansions of the first order Melnikov function. As an application, we consider limit cycle bifurcations of a piecewise near-Hamiltonian system and prove that the system has four limit cycles.
Multiple ergodic averages for variable polynomials
Authors: Koutsogiannis Andreas
Published: May 2022

In this paper we study multiple ergodic averages for "good" variable polynomials. In particular, under an additional assumption, we show that these averages converge to the expected limit, making progress related to an open problem posted by Frantzikinakis ([13,Problem 10]). These general convergence results imply several variable extensions of classical recurrence, combinatorial and number theoretical results which are presented as well.

Published: May 2022

By the principle of differential subordination and the $ q $-derivative operator, we introduce the $ q $-analog $ \mathcal{SP}^{q}_{snail}(\lambda; \alpha, \beta, \gamma) $ of certain class of analytic functions associated with the generalized Pascal snail. Firstly, we obtain the coefficient estimates and Fekete-Szegö functional inequalities for this class. Meanwhile, we also estimate the corresponding symmetric Toeplitz determinant. Secondly, for all the above results we provide the corresponding results for the reduced classes $ \mathcal{SP}^{q}_{snail}(\alpha, \beta, \gamma) $ and $ \mathcal{RP}^{q}_{snail}(\alpha, \beta, \gamma) $. Thirdly, we characterize the Bohr radius problems for the function class $ \mathcal{SP}^{q}_{snail}(\alpha, \beta, \gamma) $. Lastly, we establish certain results for some new subclasses of functions defined by the neutrosophic Poisson distribution series.
Mathematical modelling and analysis of coffee berry disease dynamics on a coffee farm
Authors: Melese Abdisa Shiferaw , Makinde Oluwole Daniel , Obsu Legesse Lemecha
Published: May 2022

This paper focuses on a mathematical model for coffee berry disease infestation dynamics. This model considers coffee berry and vector populations with the interaction of fungal pathogens. In order to gain an insight into the global dynamics of coffee berry disease transmission and eradication on any given coffee farm, the assumption of logistic growth with a carrying capacity reflects the fact that the amount of coffee plants depends on the limited size of the coffee farm. First, we show that all solutions of the chosen model are bounded and non-negative with positive initial data in a feasible region. Subsequently, endemic and disease-free equilibrium points are calculated. The basic reproduction number with respect to the coffee berry disease-free equilibrium point is derived using a next generation matrix approach. Furthermore, the local stability of the equilibria is established based on the Jacobian matrix and Routh Hurwitz criteria. The global stability of the equilibria is also proved by using the Lyapunov function. Moreover, bifurcation analysis is proved by the center manifold theory. The sensitivity indices for the basic reproduction number with respect to the main parameters are determined. Finally, the numerical simulations show the agreement with the analytical results of the model analysis.
Health-related Quality of Life Instrument With 8 Items for Use in Patients With Type 2 Diabetes Mellitus: A Validation Study in Korea
Authors: Kim Juyoung , Lee Hyeon-Jeong , Jo Min-Woo
Published: May 2022

Objectives: This study assessed the validity and reliability of the Health-related Quality of Life Instrument with 8 Items (HINT-8) in patients with diabetes. HINT-8 is a newly-developed, generic health-related quality of life (HRQoL) instrument.Methods: Three HRQoL instruments—HINT-8, EuroQoL 5-Dimension 5-Level (EQ-5D-5L), and Short Form Health Survey version 2.0 (SF-36v2)—were provided to 300 patients with diabetes visiting a tertiary hospital for follow-up visits in Korea. The HRQoL scores obtained using the HINT-8 were evaluated for subgroups with known differences based on demographics and diabetes-related characteristics (known-group validity). The mean scores of the instruments were compared between groups segmented by their responses to the HINT-8 (discriminatory ability). Correlation coefficients of the HINT-8 with other instruments were calculated (convergent and divergent validity). The Cohen kappa and intra-class correlation coefficient (ICC) were also evaluated (test-retest reliability).Results: The average HINT-8 indexes were lower among women, older, and less-educated subjects. Subjects who did not list any problems on the HINT-8 had significantly higher HRQoL scores than those who did. The correlation coefficients of the HINT-8 with the EQ-5D-5L index and EuroQoL visual analogue scale were 0.715 (p<0.001) and 0.517 (p<0.001), respectively. The correlation coefficients between the HINT-8 index and the scores of 8 domains of the SF-36v2 ranged from 0.478 (p<0.001) to 0.669 (p<0.001). The Cohen kappa values for the HINT-8 ranged from 0.268 to 0.601, and the ICC of the HINT-8 index was 0.800 (95% confidence interval [CI], 0.720 to 0.860).Conclusions: This study showed that the HINT-8 is a valid and reliable HRQoL instrument for patients with diabetes.

El dramaturgo Angel Guimerá, Tenerife y Cuba: raíces de una vinculación
Authors: Guimerá Ravina Agustín
Published: May 2022

Se estudian las raíces de la vinculación de Angel Guimerá a su tierra natal, Santa Cruz de Tenerife. El nacimiento del dramaturgo en esta ciudad el año 1845 no es fruto de una casualidad. El hecho debe ser inscrito dentro de un contexto más general: el establecimiento de un importante grupo de catalanes en Canarias durante la primera mitad del siglo XIX, al amparo del comercio y la navegación. El análisis de estas circunstancias económicas y sociales constituye el objetivo de este trabajo.

A la búsqueda de la 'felicidad' perdida. La expedición Malaspina o la interrogación sociológica del imperio
Authors: Vericat José
Published: May 2022

La expedición española alrededor del mundo a fines del s. XVIII constituye un intento por parte de la monarquía ilustrada de desvelar las claves de una legalidad -la sociológica- que permitiese reciclar el poder imperial ante el fracaso irreparable de lo político, lo militar y lo económico. La heurística de esta legalidad, en el contexto de las expediciones científicas de la época, se configura como afín a la estética de la jardinería barroca.

Los "Naufragios" de Alvar Núñez Cabeza de Vaca: notas sobre la relevancia antropológica del texto
Authors: Pupo-Walker Enrique
Published: May 2022

Analizando las referencias de Cabeza de Vaca a las sociedades indígenas, se postula por el autor, más que una valoración estrictamente informativa o etnohistórica, un análisis antropológico en un doble sentido: en cuanto la obra revela una reflexión comparada sobre las sociedades americanas, y en cuanto que hoy disponemos de una teoría antropológica para entender mejor la disposición del autor ante "los otros". A la reflexión propiamente antropológica actual, se suma el enfoque del psicoanálisis y de la literatura para mejor entender la paradoja en que se coloca Alvar Núñez en su relación cotidiana con los indios del norte de Méjico: si por un lado el relator se presenta como un viajero evangélico, por otro asume mucho de las creencias y conocimientos indígenas a la hora de ejercer su oficio de médico mágico.

El indio americano en la filosofía política de John Locke
Authors: Castilla Urbano Francisco
Published: May 2022

Análisis de la obra de John Locke para comparar el tratamiento que en ella recibe todo lo relacionado con América: las obras sobre el Nuevo Mundo y sus habitantes. Se demuestra que su biografía contiene numerosos elementos de contacto con lo americano, sacando a la luz el interés ideológico que envuelve su filosofía política y concluyendo que la defensa del empirista inglés corno fundamentadar de los orígenes de la historia de la antropología no se encuentra justificada.
Capoche, Potosí y la coca. El consumo popular de estimulantes en el siglo XVII
Authors: Saignes Thierry
Published: May 2022

A partir de un informe inédito (1610) del conocido minero potosino Luis Capoche, se refutan las interpretaciones tradicionales sobre la disminución, desde los primeros años del siglo XVII, del consumo de coca en Potosí. No se trata d e una contracción del mercado por la disminución demográfica y el cambio de patrones alimentarios (extensión del pan de trigo y el vino), sino de un profundo cambio cultural: la alteración en el uso de estimulantes entre la población del yacimiento minero. Se asocia esta novedad a la irrupción de una nueva generación más acostumbrada al trabajo minero, con más posibilidades económicas y, probablemente, más insertada en el mercado colonial.
Efectos de Potosí sobre la población indígena del Alto Perú. Pacajes a mediados del siglo XVII
Authors: Cañedo-Argüelles Fábrega Teresa
Published: May 2022

La actual provincia de Pacajes (Bolivia) ha servido como base empírica para el estudio de la mita de Potosí. Los principales puntos que se han abordado son los siguientes: el sistema de trabajo, las distintas formas de prestaciones laborales que no siempre tenían un cauce oficial a través de la mita, así como las implicaciones que tales irregularidades tuvieron en las clases indígenas dirigentes y en las propias comunidades, cuyos miembros iniciaron a raíz de ello un proceso de huida buscando amparo en las propiedades rurales de otras regiones. Asimismo se han analizado los cambios producidos en la estructura demográfica y social de los pueblos como consecuencia de este proceso.
