Authors: Hustad Eldbjørg , Myklebust Tor Åge , Gulati Sasha , Aasly Jan O.
Published: July 2021

Objective Few studies have followed Parkinson’s disease (PD) patients from the time of diagnosis to the date of death. This study compared mortality in the Trondheim PD cohort to the general population, investigated causes of death and analyzed the associations between mortality and age at disease onset (AAO) and cognitive decline defined as Montreal Cognitive Assessment (MoCA) score below 26.Methods The cohort was followed longitudinally from 1997. By the end of January 2020, 587 patients had died. Comparisons to the Norwegian population were performed by calculating standardized mortality ratios (SMRs). Survival curves were estimated using the standard Kaplan-Meier estimator, and multivariable Cox proportional hazard models were estimated to investigate associations.Results SMR was 2.28 [95% confidence interval (CI): 2.13–2.44] for the whole cohort. For participants with AAO 20–39 years, the SMR was 5.55 (95% CI: 3.38–8.61). Median survival was 15 years (95% CI: 14.2–15.5) for the whole cohort. Early-onset PD (EOPD) patients (AAO < 50 years) had the longest median survival time. For all groups, there was a significant shortening in median survival time and an almost 3-fold higher age- and sex-adjusted hazard ratio for death when the MoCA score decreased below 26.Conclusion PD patients with an AAO before 40 years had a more than fivefold higher mortality rate compared to a similar general population. EOPD patients had the longest median survival; however, their life expectancy was reduced to a greater degree than that of late-onset PD patients. Cognitive impairment was strongly associated with mortality in PD.
Existence results for double phase problems depending on Robin and Steklov eigenvalues for the p-Laplacian
Authors: Manouni Said El , Marino Greta , Winkert Patrick
Published: July 2021

In this paper we study double phase problems with nonlinear boundary condition and gradient dependence. Under quite general assumptions we prove existence results for such problems where the perturbations satisfy a suitable behavior in the origin and at infinity. Our proofs make use of variational tools, truncation techniques and comparison methods. The obtained solutions depend on the first eigenvalues of the Robin and Steklov eigenvalue problems for the p-Laplacian.

Published: July 2021

The research on facile, low-cost, and green process for the uniform dispersion of graphene nanoplatelets (GNPs) into polymer matrix has always been a considerable challenge in practical applications. The Van der Waals interaction between graphene layers can easily cause aggregation of the nanofillers. Here, we propose a new method to solve this problem by involving solid-state shear mixing to obtain a well-dispersed nanocomposite. The comprehensive properties of nanocomposite, including antistatic properties, mechanical properties, and thermal stability, can be significantly enhanced by this method. The surface resistivity of the nanocomposite can be up to 2.4 × 107 Ω sq−1 under 1 wt% content of GNPs, which is significantly better than the value obtained by conventional melting compounding and meets the required standard of less than 3 × 108 Ω sq−1 for actual application antistatic materials. The impact strength of the nanocomposite increased by 120.8% when compared with neat PP. At the same time, the heat distortion temperature and initial decomposition temperature of the nanocomposite with only 0.5 wt% content of GNPs are improved by 11.7°C and 110°C, respectively. In addition, GNPs is a heterogeneous nucleating agent that leads PP to emerge β crystal form. This study provides an effective and practical reference for the broad-scale industrial preparation of polymer-based graphene nanocomposites.

Adalékok a 18. századi Szabolcs, Szatmár és Bereg vármegyei boszorkányság kutatásához
Authors: Kocsis Annamária
Published: July 2021

A tanulmány a 18. századi Szabolcs, Szatmár és Bereg megyei boszorkányságot vizsgálja. A boszorkányperek társadalmi ellentéteket tárnak fel nemcsak országos, hanem helyi szinten is, ennél fogva kiváló forrásbázisát képezik a konfliktuskutatásnak.  
A boszorkányüldözés során a perbefogottak mintegy 90%-a nő volt. A boszorkányperek kutatása során ezért a nő mint társadalmi kategória jelenik meg és az interdiszciplináris kutatások a nő helyzetét a maga komplexitásában mutatják be. Kiemelt figyelmet fordítva a férfi-nő kapcsolat különböző megjelenési formáira.  
A magyarországi boszorkányperek kutatása során már megtörtént a legfontosabb források feltárása és azok publikálása. Azonban az egyes területek, kisebb-nagyobb földrajzi régiók, sajátosságait bemutató művek csak nagyon kis számban állnak rendelkezésre. Különösen az általam választott megyék területén. Jelen munka elsődleges célja a nevezett három vármegye boszorkánypereinek kvantitatív, kvalitatív és tartalomelemző módszerrel történő, különböző szempontok szerinti (vád, vádlottak nemi összetétele és aránya, büntetési tételek típusa) feldolgozás elemzése, a tipikusságok és a sajátosságok kiemelése.  
Az összefüggések megállapítását, a magyarázatok elkészítését és értékelését követően, a kapott eredményeknek köszönhetően pontosabb képet kaphatunk majd a boszorkányságról, mint magyarországi jelenségről. Továbbá a vizsgált terület, tehát Szabolcs, Szatmár és Bereg vármegyék boszorkánypereinek sajátosságaira is rálátást kaphatunk.

Anousaki, E, Zaras, N, Stasinaki A-N, Panidi, I, Terzis, T, and Karampatsos, G. Effects of a 25-week periodized training macrocycle on muscle strength, power, muscle architecture, and performance in well-trained track and field throwers. J Strength Cond Res 35(10): 2728–2736, 2021—The purpose of the study was to investigate the effect of a 25-week macrocycle on strength, power, vastus lateralis (VL) muscle architecture, and competitive track and field throwing performance, in well-trained track and field throwers. Twelve well-trained throwers (age: 24.3 ± 5.5 years, mass: 96.6 ± 9.9 kg, and height: 1.82 ± 0.02 m), participated in the study. All athletes followed a 25-week periodized training program divided into 3 training phases: the hypertrophy/maximum strength phase, the maximum strength/power phase, and the power/speed phase. Measurements were performed at the beginning of the training period (T1), after the first training phase (T2), and after the end of the training period (T3). Measurements included the following: competitive track and field throwing performance; shot put throws; maximum strength (1-RM) in snatch, clean, and squat; countermovement jump (CMJ); and VL muscle architecture. Competitive track and field throwing performance and shot put throws increased from T1 to T3 by 10.9 ± 3.2% (p = 0.001) and 5.1 ± 6.4% (P = 0.049), respectively. 1 RM strength in snatch and squat increased significantly from T1 to T3 by 9.7 ± 8.9% (p = 0.001) and 9.9 ± 7.1% (p = 0.002), respectively. Countermovement jump height increased only from T1 to T2 by 10.9 ± 11.8% (p = 0.026). A significant increase was found for VL fascicle length between T1 and T3 (9.6 ± 11.1%, p = 0.049). Strong correlations were found between the percentage increase of competitive track and field throwing performance with 1 RM snatch (r = 0.571, p = 0.046) and with shot put throws (r = 0.715, p = 0.001). Twenty five weeks of training may increase performance and VL fascicle length, whereas increases in 1 RM snatch and in shot put throws are associated with competitive track and field throwing performance in well-trained throwers.

Bielitzki, R, Behrendt, T, Behrens, M, and Schega, L. Current techniques used for practical blood flow restriction training: a systematic review. J Strength Cond Res 35(10): 2936–2951, 2021—The purpose of this article was to systematically review the available scientific evidence on current methods used for practical blood flow restriction (pBFR) training together with application characteristics as well as advantages and disadvantages of each technique. A literature search was conducted in different databases (PubMed, Web of Science, Scopus, and Cochrane Library) for the period from January 2000 to December 2020. Inclusion criteria for this review were (a) original research involving humans, (b) the use of elastic wraps or nonpneumatic cuffs, and (c) articles written in English. Of 26 studies included and reviewed, 15 were conducted using an acute intervention (11 in the lower body and 4 in the upper body), and 11 were performed with a chronic intervention (8 in the lower body, 1 in the upper body, and 2 in both the upper and the lower body). Three pBFR techniques could be identified: (a) based on the perceptual response (perceived pressure technique), (b) based on the overlap of the cuff (absolute and relative overlap technique), and (c) based on the cuffs' maximal tensile strength (maximal cuff elasticity technique). In conclusion, the perceived pressure technique is simple, valid for the first application, and can be used independently of the cuffs' material properties, but is less reliable within a person over time. The absolute and relative overlap technique as well as the maximal cuff elasticity technique might be applied more reliably due to markings, but require a cuff with constant material properties over time.
A Cre-Dependent CRISPR/dCas9 System for Gene Expression Regulation in Neurons

Published: July 2021

Site-specific genetic and epigenetic targeting of distinct cell populations is a central goal in molecular neuroscience and is crucial to understand the gene regulatory mechanisms that underlie complex phenotypes and behaviors. While recent technological advances have enabled unprecedented control over gene expression, many of these approaches are focused on selected model organisms and/or require labor-intensive customization for different applications. The simplicity and modularity of clustered regularly interspaced short palindromic repeats (CRISPR)-based systems have transformed genome editing and expanded the gene regulatory toolbox. However, there are few available tools for cell-selective CRISPR regulation in neurons. We designed, validated, and optimized CRISPR activation (CRISPRa) and CRISPR interference (CRISPRi) systems for Cre recombinase-dependent gene regulation. Unexpectedly, CRISPRa systems based on a traditional double-floxed inverted open reading frame (DIO) strategy exhibited leaky target gene induction even without Cre. Therefore, we developed an intron-containing Cre-dependent CRISPRa system (SVI-DIO-dCas9-VPR) that alleviated leaky gene induction and outperformed the traditional DIO system at endogenous genes in HEK293T cells and rat primary neuron cultures. Using gene-specific CRISPR sgRNAs, we demonstrate that SVI-DIO-dCas9-VPR can activate numerous rat or human genes (GRM2,Tent5b,Fos,Sstr2, andGadd45b) in a Cre-specific manner. To illustrate the versatility of this tool, we created a parallel CRISPRi construct that successfully inhibited expression from a luciferase reporter in HEK293T cells only in the presence of Cre. These results provide a robust framework for Cre-dependent CRISPR-dCas9 approaches across different model systems, and enable cell-specific targeting when combined with common Cre driver lines or Cre delivery via viral vectors.

Published: July 2021

Bearing is a small component that widely uses in industries, either in rotary machines or shafts. Faulty in bearing might cause massive downtime in the industries, which lead to loss of revenue. This paper intends to find the consequential statistical time-domain-based features that can be used in classification from accelerometry signals for the bearing condition. An accelerometer was used as the data logger device to attain the condition signals from the bearing. Machinery Failure Prevention Technology (MFPT) online dataset has three different bearing conditions: baseline condition, inner faulty condition, and outer faulty condition. Extraction of eight statistical time-domain features was done, which is root-mean-square (RMS), minimum (Min), maximum (Max), mean, median, standard deviation, variance, and skewness. The identification of informative attributes was made using a filter-based method, in which the scoring is done by using the Information gain ratio. For the extracted features, the data splitting of training data to testing data was set to the ratio of 70% and 30%, respectively. The selected feature for classification is then fed into various types of classifiers to observe the effect of this feature selection method on the classification performance. From this research, six features were identified as the significant features: variance,  standard deviation, Min, Max, mean, and RMS. It is said that the classification accuracy of the training data and the testing data using the filter-based feature selection method is equivalent to the classification accuracy of all the features selected.
Experiment of Pullout Expansion Anchor in Installation Cast in Place and Post Installed with Concrete Breakout Failure
Authors: Huda Amirul , Apriyatno Henry
Published: July 2021

Abstract: The use of anchors in construction is gaining popularity to connect steel and concrete constructions, and to transmit tensile loads acting onto the concrete. This research aims to find out the difference in the strength of anchor based on two methods of installations that are cast in place compared to post installed with the influence of effective depth, diameter of anchor and quality of concrete, and failure of concrete breakout. Expansion anchor used in this study is "Sanko" M12x100 and ready-mix concrete PT Bonindo Ungaran, fc 25 MPa with 6 pieces of test specimens of 300x300x150 mm. Each specimen has 4 anchors with a distance between the anchors of 100 cm, the distance between the anchors to the edge of the concrete 100 mm, and the depth of installation (hef) of 60 mm. The result of the study is the predicted value of the anchor pullout capacity with the failure of concrete breakout due to the theoretical pullout, namely 42,223 N, anchor pullout test results with cast in place method of 40,574 N and post installed method by 37,494 N. Tensile strength tests (material) of anchor (fy) 338 MPa, for flat concrete compressive strength strength of (fâ€™c) 25,698 MPa. The results of the cast in place pullout test are larger and better than post installed (40574 N37494 N). Failure that occurred in cast in place method is a failure of concrete breakout and post installed method has occurred slip. Failures that occur are relevant to the theory.

Authors: Lu Chun-feng , Liu Wang-shu , Ge Xiao-qin , Xu Feng
Published: July 2021

The aim of the present study was to evaluate the association between adenosine deaminase (ADA) levels and diabetic kidney disease (DKD) in patients with type 2 diabetes (T2D). In this study, patients with T2D who had been screened for DKD were recruited. Patients with an estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m2 or a urinary albumin-to-creatinine ratio (UACR) ≥ 30 mg/g for 3 months were identified as having DKD. The prevalence of DKD was 13.3%, and the range of serum ADA levels was 4–37 U/L. Serum ADA levels were positively associated with cystatin C levels and UACR (r = 0.295 and r = 0.302, respectively, both P < 0.05) and negatively associated with eGFR (r = −0.342, P < 0.05). The proportion of participants with DKD increased significantly from 3.8% in the first tertile (T1) to 13.6% in the second tertile (T2) and 25.9% in the third tertile (T3) of ADA (P for trend < 0.001). After adjusting for clinical risk factors for DKD via multiple logistic regression, the corresponding odds ratios (ORs) of DKD for the participants in T2 and T3 vs those in T1 of ADA were 5.123 (1.282–20.474) and 10.098 (1.660–61.431), respectively. Receiver operating characteristic (ROC) analysis revealed that the optimal cutoff value of ADA to indicate DKD was 10 U/L. Its corresponding sensitivity and specificity were 75.5 and 56.4%, respectively. Our results demonstrated that serum ADA levels were closely associated with DKD and partly reflect the risk of DKD in patients with T2D.
Образи «нових людей» у повісті «Семен Жук і його родичі» О. Кониського
Authors: Бойко Надія
Published: July 2021

Мета статті – простежити концепцію творення образу «нових людей» в ідеологічній повісті «Семен Жук і його родичі» Олександра Кониського, проаналізувати мотиви їхнього екзистенційного вибору. Дослідницька методика. У розвідці поєднано біографічний, історико-генетичний та культурноісторичний підходи вивчення літературного явища. Результати дослідження. Ідеологічна проза О. Кониського дозволяє простежити еволюцію образу народника, «нової людини» в українській літературі другої половини ХІХ ст. – від зародження, набуття досвіду шляхом реалізації «малих справ», етап «культурного опору», розчарування і до самознищення. Поява в українській літературі ідеологічної повісті була закономірним процесом, зумовленим новими суспільними умовами, пошуком нового об’єкта художньої обсервації та функціями, які покладалися на неї: пропагування нових ідей і виховання покоління української інтелігенції. Ідеологічні повісті Кониського віддзеркалюють ідейно-світоглядні переконання самого автора, вони цінні як відтворенням подій «по гарячих слідах» (І. Франко), а й тим, як ці події сприймалися українським народником. Наукова новизна полягає у незаангажованому прочитанні ідеологічної прози другої половини ХІХ ст. як цілісного явища; осмисленні авторського задуму образу «нової людини». Практичне значення. Результати дослідження можуть бути використані для подальшого вивчення літературного процесу другої половини ХІХ ст., формозмістових особливостей української прози цього періоду; як додатковий матеріал при підготовці навчальних курсів, наукових семінарів і спецкурсів з історії української літератури.
Algunas propuestas para mejorar la formación del profesorado de Chile a la luz de las prácticas pedagógicas de éxito en el País Vasco

Published: July 2021

El propósito de este trabajo es realizar una revisión de la literatura existente para identificar algunas propuestas de ciertas experiencias educativas de éxito en la Comunidad Autónoma del País Vasco para ayudar a fortalecer los procesos de formación inicial y continua del profesorado en la Universidad Arturo Prat de Chile. Los nuevos escenarios sociales presentes en el mundo actual y las nuevas demandas para la educación y el profesorado constituyen una tarea que debe ser atendida con celeridad y responsabilidad. Desde esta inquietud, primeramente, se ha descrito cómo es actualmente la formación docente en Chile y cómo se entiende la formación del profesorado, para pasar seguidamente al planteamiento del sistema educativo del País Vasco. En este contexto territorial, se ha revisado la literatura existente sobre distintas experiencias educativas consideradas exitosas por el Gobierno Vasco porque impactan en alumnado y docentes, en la escuela y los contextos sociales en que el centro está imbricado, ya que cuidan mucho las relaciones personales y los aspectos organizativos. Los centros objeto de revisión han sido: Comunidades de Aprendizaje, Sistema Amara Berri, Pedagogía de la Confianza y el Modelo Pedagógico de Antzuola. La principal conclusión pone de relieve que en todas las experiencias se opera un cambio en las interacciones de las personas de la comunidad escolar donde cobra gran importancia el contexto en que la persona vive, crece y se relaciona, aspectos que no son tenidos en cuenta en la formación del profesorado en Chile.
Bio-based rigid polyurethane foam prepared from apricot stone shell-based polyol for thermal insulation application – Part 2: Morphological, mechanical, and thermal properties
Authors: Fidan Muhammed Said , Ertaş Murat
Published: July 2021

The procedure for the liquefaction of apricot stone shells was reported in Part 1. Part 2 of this work determines the morphological, mechanical, and thermal properties of the bio-based rigid polyurethane foam composites (RPUFc). In this study, the thermal conductivity, compressive strength, compressive modulus, thermogravimetric analysis, flammability tests (horizontal burning and limited oxygen index (LOI)) in the flame retardants), and scanning electron microscope (SEM) (cell diameter in the SEM) tests of the RPUFc were performed and compared with control samples. The results showed the thermal conductivity (0.0342 to 0.0362 mW/mK), compressive strength (10.5 to 14.9 kPa), compressive modulus (179.9 to 180.3 kPa), decomposition and residue in the thermogravimetric analysis (230 to 491 °C, 15.31 to 21.61%), UL-94 and LOI in the flame retardants (539.5 to 591.1 mm/min, 17.8 to 18.5%), and cell diameter in the SEM (50.6 to 347.5 μm) of RPUFc attained from liquefied biomass. The results were similar to those of foams obtained from industrial RPUFs, and demonstrated that bio-based RPUFc obtained from liquefied apricot stone shells could be used as a reinforcement filler in the preparation of RPUFs, specifically in construction and insulation materials. Moreover, liquefied apricot stone shell products have potential to be fabricated into rigid polyurethane foam composites.

Issues of maturation and functional activity of cells are highlighted. The stages of the vital activity of neutrophils are shown – migration, chemotaxis, adhesion, oxygen explosion, absorption, degranulation, apoptosis. Special attention is paid to neutrophilic extracellular traps and the importance of myeloperoxidase. Today, these cells are increasingly viewed as a potential biomarker with specific treatments.
Padronização de uma masculinidade e virilidade por meio da revista Playboy Brasil na década de 1980
Authors: Voks Douglas Josiel
Published: July 2021

ser homem, masculino ou viril são construções históricas que ganham diferentes significações ao longo do tempo e do espaço. Observar historicamente essas significações é essencial para compreender rupturas, continuidades ou repetibilidades em torno de prescrições e normatividades de gênero. Por isso, neste trabalho, investiga-se como se estabeleceu a construção de um ideal de homem por meio dos discursos de masculinidade e virilidade da revista Playboy Brasil na década de 1980, e como esses discursos serviram para constituir um novo padrão de masculinidade. Inicia-se o trabalho fazendo uma breve revisão teórica sobre os estudos das masculinidades e como estes têm contribuído para as discussões de gênero nas últimas décadas. Em seguida, aborda-se a virilidade em contraponto com a masculinidade, desde a construção da noção de virilidade e suas mudanças históricas até a sua problematização dentro da revista Playboy. E, por fim, é analisada a construção da imagem de uma mulher “ideal” para legitimar um homem “ideal” na Playboy. Metodologicamente, esse trabalho parte da análise do discurso proposta por Michel Foucault. Na análise do corpo documental, percebe-se que a revista tentou criar um ideal de homem com um projeto que incidia diretamente em uma outra masculinidade/virilidade, gerando conflitos e tensões de gênero.
Elementos para comprender la construcción de la masculinidad militar paraguaya en el siglo XX
Authors: Duarte-Sckell Jazmín
Published: July 2021

la masculinidad militar es uno de los modelos de virilidad instalados en el imaginario paraguayo por ser eje del discurso heroico, y base de la identidad nacionalista. En este artículo, se analiza la construcción de dicho fenómeno en el siglo XX a partir de las investigaciones existentes sobre autoritarismo y nacionalismo en Paraguay con el fin de visibilizar el proceso de establecimiento de esta masculinidad por medio de su expresión simbólica, su relevancia en la práctica política y su reproducción en el ámbito educativo. Sin ser la única, es una de las masculinidades hegemónicas del país por lo cual debe comprenderse como históricamente construida y propulsada desde el Estado autoritario.
Los imperativos psicológicos de la gestión empresarial en Medellín a través de la revista Temas (1941-1948)
Authors: Posada-Morales Juan-Esteban
Published: July 2021

en este artículo se analiza los imperativos de un discurso psicológico que como imaginario colectivo y como una nueva cultura fue propuesto para afrontar los retos económicos, sociales y subjetivos de algunos medellinenses a mediados del siglo XX. A su vez, se analiza el tipo de la personalidad que se promovía a través de la “gestión empresarial de sí”, y cómo a través de la revista Temas de Medellín (Colombia) se empezaron a hacer explícitas las formas y los valores asociados a los procesos que impulsaron una nueva manera de “ser en el mundo”. El objetivo de este tipo de relato fue el de promover el emprendimiento, el individualismo, el bienestar, el trabajo, la “raza”, los negocios, el comercio, la felicidad, la cultura de empresa, la autovalorización, la gestión del espíritu en la avidez de bienes materiales y de riquezas, el desarrollo personal, el poder de la mente sobre el cuerpo y la espiritualidad como los valores, emociones y placeres asociados a la economía de producción y de consumo. Así mismo, se estudian los valores de este tipo de capitalismo emergente como la síntesis de todas las aspiraciones humanas y como la capacidad más voluptuosa de la ciudadanía de Medellín en ese momento histórico. Para ello se examina la publicación periódica Temas y se concluye que a través de estrategias educativas se generó una memoria social para el perfil empresarial basada en el éxito y en los privilegios de clase centrados en la acumulación de capital material y humano, lo cual llevó a una forma específica de clasificación social resumida bajo la categoría de “gestión empresarial”.

Ciudades argentinas en el contexto del cambio climático: exploraciones para el análisis del riesgo y la resiliencia urbana
Authors: Zulaica Maria Laura , Vazquez Patricia Susana
Published: July 2021

América Latina evidencia un acelerado proceso de urbanización bajo un modelo de desarrollo que genera e intensifica problemas sociales y ambientales. A esto se suman los riesgos desencadenados por el cambio climático que afectan las ciudades actuales. En Argentina sus efectos se manifiestan diferencialmente sobre las regiones, impactando en las ciudades y asentamientos. Este trabajo propone explorar el riesgo ambiental al que se enfrentan ciudades argentinas en un contexto de cambio climático en dos dimensiones: amenaza y resiliencia. Se construyeron dos índices sintéticos aplicando la metodología de Valor Índice Medio para cada dimensión y, posteriormente, se articularon los resultados definiendo categorías de riesgo.

Crónica de una utopía urbana: arabépolis de Abu Dabi, una ciudad emiratí en un contexto de cambio ambiental global
Authors: Avendaño Arias Johan Andrés
Published: July 2021

Las ciudades contemporáneas de la península arábica —Abu Dabi, Dubái, La Meca, Doha, Medina, Riad, Dammam, Kuwait, Manama—, han experimentado abruptas transformaciones con un factor común: una economía petrodolarizada a partir de 1967. Pese a sus contextos y orígenes geohistóricos disímiles, actualmente, son claros nodos jerárquicos centrales de la economía mundo, un tipo de ciudades globales de nueva generación. ¿Cómo no preguntarse? ¿Qué rol juegan y qué características poseen estas aglomeraciones, en tanto proyecto urbano, que se soportan en la dominación de las fuerzas agrestes del desierto, en un contexto de crisis ambiental, y por qué no, social global? Si bien en otras latitudes también emergen como champiñones ciudades suntuosas llenas de incontables rascacielos, las arabépolis o ciudades árabes actuales —tal como es la propuesta a ser tipificadas— con las mayores reservas de gas y petróleo del mundo, un estilo arquitectónico, urbanístico y simbólico peculiar, y sin antecedente industrial: ¿serían en sí mismas una utopía o una distopía urbana? Poniendo foco en Abu Dabi, y exponiendo algunas hipótesis para resolver esos cuestionamientos, se hila este texto, verificando particularidades y combinando métodos geohistóricos, de observación y revisión documental, con el fin de incentivar nuevos escenarios de reflexión.

Published: July 2021

El proceso de periurbanización en la Zona Metropolitana Puebla, Tlaxcala (ZMPT), en México, ha incluido en gran medida, una ocupación irregular del suelo estrechamente relacionada al deterioro ambiental de una zona de alto valor ecológico. Este artículo presenta un estudio de los procesos de crecimiento poblacional y expansión urbana que han impactado en el cambio de uso del suelo en la periferia norte de la ZMPT, y como parte de ella, en el Parque Nacional La Malinche. Se llevó a cabo un análisis de la evolución del comportamiento demográfico y de la expansión urbana en la zona, así como de la transformación de los usos del suelo por medio de imágenes satelitales de distintas fechas. El trabajo realizado permitió contar con el panorama social y económico necesario para cuantificar y establecer los efectos en los cambios de uso del suelo a nivel regional y sus consecuencias, sustentando el valor de dicho argumento. Fue posible caracterizar el proceso urbano expansivo y verificar que ha sido la causa principal de la aceleración del fenómeno que ha afectado la conservación del medio ambiente y la calidad de vida de la población.

Leadership is critical for the functioning of society and of any organization, and the effectiveness is incumbent on leader and follower congruence. The effectiveness of a leader is therefore inevitably contingent to the leader’s ability to develop a balance between the objectives of the followers, the leader and the organization. This is compounded by the factors that inform leader behavior, follower expectation and the tasks to be performed. Chief amongst these would be culture, religion, levels of follower education, and the tasks to be performed. The Gaza Strip is a heavily militarized, paternalistic and strongly religious environment, allowing for an environment that encourages transactional leadership. The research sought to establish the acceptability of transactional leadership at a large telecommunications organization in the Gaza Strip. The target population was employees of the organization and their perceptions about transactional leadership. The findings indicate a high acceptability of transactional leadership style by the employees of the organization.

Published: July 2021

An analytical framework is presented for the evaluation of quantile probability forecasts. It is demonstrated using weekly quantile forecasts of changes in the number of US COVID-19 deaths. Empirical quantiles are derived using the assumption that daily changes in a variable follow a normal distribution with time varying means and standard deviations, which can be assumed constant over short horizons such as one week. These empirical quantiles are used to evaluate quantile forecasts using the Mean Squared Quantile Score (MSQS), which, in turn, is decomposed into sub-components involving bias, resolution and error variation to identify specific aspects of performance, which highlight the strengths and weaknesses of forecasts. The framework is then extended to test if performance enhancement can be achieved by combining diverse forecasts from different sources. The demonstration illustrates that the technique can effectively evaluate quantile forecasting performance based on a limited number of data points, which is crucial in emergency situations such as forecasting pandemic behavior. It also shows that combining the predictions with quantile probability forecasts generated from an Autoregressive Order One, AR(1) model provided substantially improved performance. The implications of these findings are discussed, suggestions are offered for future research and potential limitations are considered.

Published: July 2021

This study examines the socioeconomic determinants of women’s empowerment or bargaining power among married couples living in farm households in Nigeria. A multistage random sampling technique is employed to collect cross-sectional data from 320 farm households aged between 15 to 50 years. Women’s empowerment or bargaining power is measured using 18 questions, and a Tobit regression model is used to analyze all the variables employed. According to the findings, husbands have five more years of formal education than wives and literacy rates are higher for men (62%) than for women (30%). This differenceleads to more decision-making power for men. The result shows that there is a visible gender disparity in the worth and value of assets brought into the marriage, with the men bringing around 34% while that of the women is around 3% making men the main decision-makers and women less empowered. As a policy recommendation, women’s status in society should be enhanced through investment in education and well-being. Additionally, policies and programs aimed at leveraging the bargaining power of the woman in her attempts to make decisions in the household and increasing her empowerment should be formulated and implemented by policymakers.

A behavior such as enabling two factor authentication has a positive impact on a users’ information security. It is assumed that given the benefits, users will want to perform this cybersecurity related behavior. However, some users choose not to perform the beneficial security behavior. Varied explanations have been provided as to why users choose to perform or not perform cybersecurity behaviors. The factors that influence users in the decision making of whether to perform or not perform a cybersecurity related behavior are referred to as constructs. This study seeks to combine the results of selected studied, with the aim of identifying prominent user cybersecurity behavior constructs, as well as the relationships between the constructs. The contributions made by the study is the consolidated visualization of behavior constructs that have an influence on user cybersecurity behavior. Furthermore, the study also provides practical applications of the cybersecurity behavior constructs. To achieve the goals of the study, a literature review is used as the study methodology. Data from previous studies is systematically collected, and analyzed. The study makes use of the Theoretical Domains Theory as a tool, which aids in consolidating the different behavior constructs found in cybersecurity literature. The constructs Beliefs about Capabilities, Beliefs about Consequences, Reinforcements, Social Influences, Intentions, Emotions, Social/Professional Role and Identity, Knowledge and Skills are found to have influence on cybersecurity behavior.

A biscuit is a flour-based baked food product which is accepted by all age groups. Carrageenan is a natural polysaccharide obtained from red seaweeds andis a rich source of fibre. The diets rich in fibre have a positive effect on health, thus, carrageenan was incorporated into biscuits to enhance the fibre content. Different percentages (2 to 6%) of carrageenan were incorporated in biscuits among which 6 per cent was found to be the best. Fibre rich biscuits were subjected to physiochemical analysis. The antioxidant activity and total polyphenol contents were estimated. Snap test to determine the crispiness and textural characterization of biscuit was performed and Scanning Electron Microscopy (SEM) was done to compare the morphological changes in the products due to addition of carrageenan. The stability of the product at room temperature was analysed by monitoring the textural and colour changes and development of rancidity in the product. The storage studies have revealed a shelf-life of 63 days for the product at room temperature when packed in polypropylene trays.

Published: July 2021

Colletotrichum species is considered as amajor fungal pathogen that can cause economic damage in commercial chilli production because of its ability to infect fruits both at pre- and post-harvest stages. Results obtained from the Fourier transform near-infrared spectrophotometer in chilli genotypes indicated that, there is a significant difference among the chilli genotypes for both quantitative and qualitative traits. Furthermore, capsaicin and oleoresin contents have a significant linear relationship with resistance to anthracnose at red fruit stage. Incidentally, chilli genotypes that are moderately resistant to anthracnose were significantly superior in capsaicin and oleoresin contents and fruit yield. Hence, capsaicin and oleoresin content can be used as an indirect method to predict anthracnose resistance in chilli breeding.

Published: July 2021

Powdery mildew disease of sesame occurs on epidemic scale in areas of high rainfall and humidity coupled with low night temperature causing considerable yield losses. Use of host plant resistance is the practical approach to manage this disease, but proper resistance sources with combining ability for the trait are unknown. Hence, an experiment was conducted to determine resistance in sesame genotypes against powdery mildew disease. Among the twenty four genotypes screened, none was found resistant while, nine genotypes exhibited moderately resistant to tolerant reaction and 15 genotypes exhibited susceptible reaction. Apparent rate of infection value varied and at times they did not remain consistent for given genotype and also did not show a particular trend which is attributed to genetic character of the genotype. The AUDPC values differed considerably for different genotypes. The values of AUDPC and apparent rate of infection of susceptible varieties were high as compared to moderately susceptible varieties. Genotype ‘JLS-302-11’ and ‘JLT-7’ having minimum AUDPC and apparent rate of infection value showed lowest intensity of powdery mildew while, genotype ‘JLT-408’ having maximum AUDPC and apparent rate of infection value showed highest intensity of powdery mildew.
