Optical Fermi level-tuned plasmonic coupling in a grating-assisted graphene nanoribbon system
Authors: Xu Hui , He Zhihui , Chen Zhiquan , Nie Guozheng , Li Hongjian
Published: August 2020

A novel graphene-based grating-coupled metamaterial structure is proposed, and the optical response of this structure can be obviously controlled by the Fermi level, which is theoretically regulated by the electric field of an applied voltage. The upper graphene monolayer can be intensely excited with the aid of periodic grating and thus it can be considered a bright mode. Meanwhile, the lower graphene monolayer cannot be directly excited, but it could be indirectly activated by the help of bright mode. The plasmonic polaritons resulting from the light-graphene interaction resonance can lead to a destructive interference effect, leading to a plasmonic induced transparency. This structure has a simple construction and retains the integrity of graphene. In the meantime, it can achieve a good tuning effect by adjusting the voltage regulation of microstructure array and it can obtain an outstanding reflection efficiency. Thus, this graphene-based metamaterial structure with these properties is very suitable for the plasmonic optical reflector. In contacting with the characteristics of material, the group delay of this device can reach to 0.3ps, which can well match the slow light performance. Therefore, the device is expected to make some contribution in optical reflection and slow light devices.
Plasmonic-organic hybrid electro/optic Mach-Zehnder modulators: from waveguide to multiphysics modal-FDTD modeling

Published: August 2020

Plasmonic organic hybrid electro/optic modulators are among the most innovative light modulators fully compatible with the silicon photonics platform. In this context, modeling is instrumental to both computer-aided optimization and interpretation of experimental data. Due to the large computational resources required, modeling is usually limited to waveguide simulations. The first aim of this work to investigate an improved, physics-based description of the voltage-dependent electro/optic effect, leading to a multiphysics-augmented model of the modulator cross-section. Targeting the accuracy of full-wave, 3D modeling with moderate computational resources, the paper presents a novel mixed modal-FDTD simulation strategy that allows us to drastically reduce the number and complexity of 3D-FDTD simulations needed to accurately evaluate the modulator response. This framework is demonstrated on a device inspired by the literature.
Vector optical-chirp-chain Brillouin optical time-domain analyzer based on complex principal component analysis
Authors: Zhang Jingdong , Zheng Hua , Wu Haoting , Guo Nan , Yin Guolu , Zhu Tao
Published: August 2020

A vector optical-chirp-chain (OCC) Brillouin optical time-domain analyzer (BOTDA) based on complex principal component analysis (CPCA) is proposed and experimentally demonstrated by employing a four-tone OCC probe with two orthogonal polarization states. The polarization-fading-free complex Brillouin spectrum (CBS) of the vector OCC-BOTDA is obtained by combining the amplitude and phase response spectra of the probe wave at both Brillouin gain and loss region. We utilize the CPCA method to determine the Brillouin frequency shift (BFS) directly using the measured CBS, and the sensing accuracy is improved by a factor of up to 1.4. The distributed temperature sensing is demonstrated over a 20 km standard single-mode fiber with a 6 m spatial resolution and less than 1 MHz frequency uncertainty under 10 times of trace averaging.
Letters to Sheila: Improvisational scores in creative practice research
Authors: Mees Cleo
Published: August 2020

This article argues that improvisational scores can function as valuable scaffolds to support creative practice research. Drawing on existing literatures about creative practice research, and the practices and scores of artists, including Simone Forti, Rosalind Crisp, James Hazel and Nancy Stark Smith, the article proposes seven different ways in which improvisational scores might help to focus, sustain and evolve research methods. Importantly, the author not only discusses the ways improvisational scores support research; she also uses a score to write the article itself, thus enacting the method she describes. The score she uses is based around a task – to write a series of letters to non-fiction author Sheila Heti. The resulting letters focus especially on the ways scores are used in improvised dance, and on the ways they might be applied in other fields such as writing and filmmaking. In doing so, the letters show how creative methodologies can be moved across disciplines and artistic forms to invigorate practice. They also give expression to and seek to better understand the embodied and affective dimensions of scholarship.
Choreographic practice research and emotional labour through the x-ray of affective dissonance
Authors: Ehrenberg Shantel
Published: August 2020

In this writing I offer critical illuminations and diffractions with(in) researching, producing and performing a piece of choreographic practice research titled (in)fertile territories: a performance lecture. I utilize the concept of affective dissonance as x-ray to get closer to feelings and emotional labour as an early-career researcher in an institutional context. The writing is grounded in the cultural politics of emotion, and presents choreographic practice research, feminist critical reflection, and writing as technologies mobilized in the hopes of birthing something anew with significantly personal choreographic material.
Somatic ethnographic research: Achoreographic process informed byAlexander Technique
Authors: Liska Suzanne
Published: August 2020

I write from the perspective of a dance artist interested in reflecting on and sharing my experiences of applying the Alexander Technique (AT) to a choreographic process. The inquiry was framed by dance ethnography, and I choreographed, danced, interviewed and performed with emerging to established dance artists specializing in Contact Improvisation, and interviewed and participated in lessons and workshops with AT teachers. During each phase of the research, I asked: why and how does AT guide me to embody my practice as a choreographer and dancer? This self-ethnographic research outlines an AT-inspired dance methodology using a systematic somatic process to enhance physical, mental and emotional coordination for choreographers and dancers. I propose that AT expanded my attention moment-to-moment to develop my choreographic intentions and desires.
Performing Water: Site-specific dance-making as liquid art
Authors: Coleman Lucinda
Published: August 2020

The Remnant Dance Project, Culaccini, developed site-specific dance movement in response to the waters of the Taleggio Valley, Italy, during the Nature, Art and Habitat Residency (NAHR) (2018). The intention was to respond to the Enna River system through documenting dance movement made in the region via film, photography and reflective writing. The practice-led research process was shared on the daily blog, ‘The drop of the day’. At the close of the NAHR, a short dance film, Performing Water, was made to further interrogate the nature of site-specific dance-making in water and the notion of what constitutes ‘site-dance’ in this context. In our journey of water-dance discovery, unique marks have remained on each other, the site and on things we have made, like the traces of a water vessel: culaccini. The dance made for the project was immersive and focused, constructed to invite interpretation through the use of symbolism and imagery.

Progetto Culaccini sviluppa un movimento di danza site-specific in risposta alle acque dei torrenti della Val Taleggio, Italia (2018). L’intenzione è quella di rispondere al sistema del torrente Enna documentando il movimento di danza fatto sul luogo attraverso film, fotografia e scrittura riflessiva. Questo processo di ricerca guidato dalla pratica venne condiviso quotidianamente sul blog: La goccia del giorno. Al termine della residenza Natura, Arte e Habitat, la produzione di un cortometraggio di danza ha permesso l’analisi e approfondimento della danza site-specific in acqua e la nozione di ciò che costituisce la ‘danza’ in questo contesto. Nel nostro viaggio di scoperta della danza nell’acqua, segni unici rimangono impressi uno sull’altro, il luogo e le cose che abbiamo fatto, come le tracce di un vessello d’acqua: i culaccini. La danza fatta in questo contesto è stata immersiva e focalizzata; costruita per invitare l’interpretazione attraverso l’uso di simbolismo e immagini.
Of other spaces: ‘Punk art’ and its wider contexts
Authors: Binns Rebecca
Published: August 2020

This article explores the connection between punk culture and artistic expression, drawing on a series of interviews with contemporary artists and designers who reflect the notion of ‘punk art’ and featuring their work to show how this continues to thrive in an independent context through music graphics, fanzines, comics, posters and flyers, professional work practices, such as tattoo design, and the art world. It outlines the prominent, established names in punk art and design before looking beyond it to a selection of people whose lived experience of punk is reflected in their work. This article draws out what connection, if any, there is between punk politics, values and ideals and various forms of artistic expression, while issues of high vs. low, commercial vs. DIY and collaborative vs. individualistic forms of practice provide recurrent themes throughout.
A crise política no Brasil e o impeachment de Dilma Rousseff em 2016
Authors: Cremonese Dejalma
Published: August 2020

O artigo analisa as ações sociais e políticas que levaram ao afastamento da presidente Dilma Rousseff da Presidência da República no ano de 2016. O trabalho foi elaborado a partir de pesquisa bibliográfica, análise de um banco de dados constituído a partir de leituras e fichamentos de textos, autores e reportagens online dos principais jornais do país entre os anos de 2013-2018. Inicialmente, sustentamos que o modelo político-econômico protagonizado pelo governo de FHC, marcado por mudanças nas áreas fiscal, cambial e monetária, e de Lula, sustentado no consumo e no crédito subsidiado, trouxeram avanços pontuais significativos, mas, de certa forma, esgotaram-se. A ausência de uma coalizão política do governo petista, aliada à crise econômica brasileira, foram determinantes para a eclosão de protestos generalizados promovidos por movimentos sociais conservadores por todo o país no ano de 2013 em diante. Esse cenário de instabilidade social, política e econômica, somado à infidelidade do PMDB ao governo de Dilma Rousseff, contribuíram para o seu afastamento da Presidência da República no dia 31 de agosto de 2016. Esse fato abriu espaço para a inclusão de “novos” atores no cenário político nacional, culminando na posse do vice-presidente Michel Temer.

Published: August 2020

Pediatric-onset multiple sclerosis (MS) can lead to cognitive impairment (CI). In general, in early-onset MS, there are disturbances in cognitive processes, such as information processing speed, attention, and controlling functions. Also, unlike adults with MS, children show a failure in various spheres of speech activity. The age of onset in MS, its duration and recurrence rate can affect not only the accumulation of a stable neurological deficit, but also the state of the cognitive sphere.

Objective: to study of the features of CI in children and adolescents with MS; to assess the relationship of CI to clinical characteristics, such as age at onset in the disease and its duration.

Patients and methods. The study involved 45 pediatric and adolescent patients with an established diagnosis of MS, who underwent a general neuropsychological examination of the cognitive sphere (Luria’s tests) with transfer to a point system; in addition, psychometric techniques were used to assess attention, controlling functions, memory, verbal fluency, and various types of thinking. Clinical characteristics, such as age at onset in MS and its duration at the time of the examination, were also taken into account.

Results and discussion. The leading factors that combine certain symptom complexes of CI in children and adolescents with MS were established. These factors include attention, controlling functions, auditory-verbal and visuospatial memories, various spheres of speech activity. Early-onset MS (at age of 5–8 years) was ascertained to have a greater impact on the formation of speech and controlling functions than adolescence- onset (at age of 13–16-years).

Conclusion. The risk of cognitive deficit and subsequent disability was found to be highest in early-onset MS.

Authors: Octaviani Irine , Koestiono Djoko , Aprilia Anisa
Published: August 2020

Supply chain management is not easy because there are two challenges that must be faced, that is the complexity of the supply chain structure and sudden uncertainty, therefore conditions are vulnerable to various forms of risk. In companies that produce organic fertilizer such as PT. MBA, organic fertilizer supply chain activities have the opportunity to pose risks. The purpose of this research is to identify risks and identify the causes of risk and determine the right strategy to deal with the causes of risk in supply chain activities at PT. MBA. The method used is the House of Risk (HOR) by using five indicators in the SCOR (Supply Chain Operation Reference) model, that is plan, source, manufacture, distribution and return. Risk events are identified and considered priorities, that is delays in receiving raw materials from suppliers, implementation of production not on schedule, no production process activities, unable to meet all requests, decreasing product quality during the process, product quality not in accordance with existing standards and delays product delivery (finished fertilizer) to PT. PKG. The priority risk agent is a risk agent to check inaccurate raw materials. Meanwhile, the handling strategy that is a priority to be implemented, with the hope of being able to prevent the causes of risk is coordination, stock strategy and flexible supply base.

Published: August 2020

Mudik is an annual community activity in Indonesia that is carried out simultaneously and in a short time. The government has made various physical or non-physical efforts to reduce the negative impacts arising from Mudik activity. One effort is by providing information related to the condition of Mudik routes. Study of preferences of travelers for changing Mudik routes after obtaining information is needed to anticipate these differences in decisions. The method used in the study is quantitative and qualitative descriptive analysis and uses non-parametric statistical analysis with McNemar and ChiSquare K free samples test to determine whether there are differences in decisions after providing information and differences in preferences for route changes based on factors. The study results show that the factors that cause the same route decisions for travelers who regularly Mudik with private vehicles are the fastest route, and there is no other route choice. The analysis shows that for both factors there is a preference of travelers to change the route by 68.5%, uncertainty by 15%, and not change the route by 16.5%. This study also shows there are differences in decisions after providing information, and there are no differences in route change preferences based on factors.
Immunohistochemical Detection of Intermediate Filament Nestin
Authors: Mokrý Jaroslav , Němeček Stanislav
Published: August 2020

Using Rat-401 monoclonal antibody and peroxidase immunohistochemistry we have detected IF nestin in developing and adult rat tissues. Although epitope recognized by Rat-401 antibody is relatively resistant to aldehyde f ixation and paraffin embedding, the embedding of tissue samples into polyester wax and microwave antigen retrieval of histological sections enabled us to enhance sensitivity of immunohistochemical detection and to identify cells expressing low levels of nestin. Our findings confirm that nestin is predominantly distributed in developing neural, myogenic and mesenchymal cells, i.e. cell types that have been previously described to express this intermediate filament. Furthermore, we made original findings on identification of nestin expression in additional cell types, e.g. newly formed endothelial cells of extra- and intraembryonic blood vessels, epithelial cells of the developing lens, and cells apposed to hair follicles.

Published: August 2020

De acuerdo con la teoría de ambientes positivos, los contextos donde se brinda apoyo académico pueden promover la adaptación exitosa de los estudiantes, y, a su vez, el resultado de dicha adaptación favorece su éxito académico, lo cual puede medirse con los constructos de compromiso académico y aprendizaje autorregulado en el ámbito académico. Teniendo esto en consideración, en la presente investigación se da cuenta de un trabajo de psicología positiva aplicada en el que se tuvo como objetivo evaluar la relación entre el ambiente de aprendizaje positivo (AAP), el compromiso académico y el aprendizaje autorregulado en bachilleres mexicanos. Para esto, se diseñó un estudio de tipo correlacional en el que participaron 166 estudiantes voluntarios de primer grado de bachillerato, seleccionados por conglomerados, con consentimiento informado individual y de sus padres. Del total de participantes, 76 fueron de sexo masculino (45.8 %) y 90 de sexo femenino (54.2 %), con una edad promedio de 15.2 años (DE = .43); quienes respondieron a cuestionarios sobre apoyo académico de padres, amigos pro-académicos, ambiente familiar positivo, compromiso académico y aprendizaje autorregulado. Se realizó un análisis de ecuaciones estructurales, y en los resultados se encontró, con una p < .05, que el AAP fue un factor latente formado por el apoyo académico de los padres, los amigos pro-académicos y el ambiente familiar positivo; además, en el modelo estructural, el AAP correlacionó positivamente con el compromiso académico (coeficiente estructural = .80), y este último se relacionó positivamente con el aprendizaje autorregulado de los estudiantes (coeficiente estructural = .55); finalmente el modelo estructural resultante explicó el 30 % del aprendizaje autorregulado. Para concluir, se discute respecto a la posibilidad de que el AAP promueva el compromiso académico y el aprendizaje autorregulado de los estudiantes.
Emotion regulation and healthy behaviors of the body energy balance in adults: A review of evidence
Authors: Gómez-Acosta César Andrés , Londoño Pérez Constanza
Published: August 2020

There is no document that analyzes the state of the art of scientific research published between 2013 and 2018 in relation to possible interdependence links between emotional regulation [ER] and healthy behaviors associated with Body Energy Balance [BEB] (physical activity, balanced diet and sleep hygiene). To achieve this purpose, an exploratory systematic review was conducted, whose search criteria were “emotion regulation”, “emotion dysregulation” connected with the Boolean operator “AND” to the keywords “sleep hygiene”, “eating behavior” and “physical activity”. Terms like “alexithymia”, “depression”, “stress”, “negative emotions”, and “rumination” were omitted. The methodological quality of the evidence was assessed with a patented rubric. After applying the analysis criteria, 35 articles were obtained, reporting theexistence of reciprocal associations and interactions between ER and at least one of the three behaviors associated with BEB were analyzed. It is concluded that, despite the importance of these behaviors in the vital maintenance of people and the clear impact that emotional regulation has on them, their research has not been sufficient, and more empirical studies in this regard in Latin America are needed.

Published: August 2020

En el presente trabajo se examinan las propiedades psicométricas de la versión argentina del Cuestionario Honey-Alonso de Estilos de Aprendizaje (CHAEA). Primero se analiza la estructura interna de la escala mediante un análisis factorial confirmatorio y de invarianza factorial, segmentando la muestra según facultad; luego se estudia la consistencia interna de las dimensiones confirmadas y se comparan los resultados con los obtenidos en estudios previos; posteriormente se examina la estabilidad temporal de las puntuaciones de cada dimensión; y, por último, se estudian las evidencias de validez concurrente con otra escala que evalúa enfoques de aprendizaje. Los resultados del análisis factorial confirmatorio muestran un adecuado ajuste del modelo testeado a partir de distintos métodos de estimación, mientras que con el análisis de invarianza factorial se comprueba la equivalencia métrica del modelo. Asimismo, los índices de consistencia interna son aceptables, aunque el análisis de estabilidad temporal de las dimensiones no comprueba diferencias significativas entre la primera y segunda administración del instrumento. Finalmente, en consonancia con hallazgos previos, las evidencias de validez concurrente exhiben asociaciones positivas entre los estilos de aprendizaje y el enfoque profundo, así como asociaciones negativas entre los estilos y el enfoque superficial. Al final se discuten los resultados a partir de antecedentes teóricos y empíricos.

Published: August 2020

La aceleración del ritmo de gestión organizacional plantea nuevos desafíos para las empresas, que pueden reflejarse en la intensificación de las demandas del trabajo y en que las personas expresen un aumento tanto en los niveles de intensidad en el desarrollo de sus tareas como en la sensación de una mayor presión del tiempo en su contexto laboral. Teniendo esto en cuenta, el objetivo del presente estudio fue examinar en una muestra de trabajadores colombianos las evidencias de validez de constructo y confiabilidad de la versión en español de la escala Intensification of Job Demands Scale (IDS), desarrollada por Kubicek et al. en 2015 para evaluar cinco demandas del trabajo sujetas a la intensificación la muestra estuvo compuesta por 420 profesionales del sector de servicios de la salud en Bogotá, Colombia. Para esto, se establecieron los estadísticos descriptivos, así como los índices de discriminación de los ítems, la estructura interna del instrumento mediante análisis factorial exploratorio y confirmatorio, y las evidencias de validez de constructo. Como resultado, se mantiene la estructura original de cinco factores de la prueba, que explican el 47.12 % de la varianza total; y, por medio de la utilización de modelos de ecuaciones estructurales, se evidencia un adecuado ajuste y parsimonia del modelo en congruencia con la propuesta teórica de la escala. Se concluye que esta versión en español de la IDS posee propiedades psicométricas adecuadas y que puede contribuir a la investigación en la región sobre la intensificación del trabajo como una demanda asociada aldeterioro en la salud y al bienestar en los trabajadores.

La revista continúa realizando aportes significativos para el desarrollo de la psicología en Hispanoamérica.
An Algorithm to Predict Life-Threatening Complications using Heart Rate Variability and the Circadian Heart Rate Difference with a Special Interest on Covid-19, Sudep Children with Congenital Heart Disease and Obesity
Authors: Buchhorn Reiner
Published: August 2020

Corona virus disease (COVID-19) has been declared as a pandemic by the WHO with a global mortality rate of about 3.4%. More recently the neuroinvasive potential of SARS-CoV2 was emphasized as a potential cause for respiratory failure. Such pathophysiology has been investigated in sudden unexplained death in epilepsy (SUDEP) including functional neuroimaging that demonstrates alterations to networks involved in central autonomic and respiratory control located in the brainstem. For risk stratification in these patients, one method may be heart rate and heart rate variability (HRV) monitoring. Method: For a better understanding, we compare HRV monitoring in two cases; 1.) Twenty Holter ECGs of a boy with generalized tonic-clonic seizures up to his dead at the age of 10.5 years with special interest on an acute respiratory failure at the age of 5.4 years. 2.) Thirty one Holter ECGs of a 58-year old pediatric cardiologist who survived an infection with COVID-19. During his disease 24-hour Holter electrocardiography (ECG) was performed continuously over 10 days. Moreover, 24-hour Holter ECGs from the last 10 years were available. The derived algorithm that depends on the global heart rate variability and circadian heart rate difference was proofed in 151 healthy children, 26 children with a fatal outcome or transplantation, 151 patients with operated congenital heart disease, 130 obese children and healthy adult data from literature. Results: In both cases we observe a decline of the global heart rate variability SDNN together with a loss of the circadian heart rate difference. The derived algorithm differentiate healthy children from children with a fatal outcome. The algorithm identify 7.3% of 151 patients with operated congenital heart disease and 5.4% of children with obesity as candidates for COVID-19 complications. Conclusions: A sudden decline of HRV together with a loss of the circadian heart rate difference may indicate a life-threatening complication in critical illness.

Lizana, JA, Bachero-Mena, B, Calvo-Lluch, A, Sánchez-Moreno, M, Pereira, LA, Loturco, I, and Pareja-Blanco, F. Do faster, stronger, and more powerful athletes perform better in resisted sprints? J Strength Cond Res 36(7): 1826–1832, 2022—This study aimed to analyze the relationships between different strength, power, and speed abilities and resisted sprint performance across a wide range of sled loads (10, 30, and 50% body mass [BM]). Seventy-nine young physically active male sport science students (age: 22.8 ± 3.4 years, BM: 74.2 ± 9.1 kg, and height: 175.4 ± 8.5 cm) performed 2 testing sessions. Session 1 consisted of a 20 m sprint without any additional load and with 10, 30, and 50% BM. Session 2 consisted of countermovement jump and full squat (SQ) tests. The CMJ was performed without any additional load and with loads of 30 and 50% BM, and the SQ was performed with loads corresponding to 30, 50, 70, and 90% BM. Resisted sprint times were moderate to large correlated with unloaded sprint times (r = 0.79 to 0.89), unloaded and loaded jump height (r = −0.62 to −0.71), and SQ performance (r = −0.56 to −0.71). Negative relationships were observed between velocity loss induced by each sled load and jump and SQ performance. The magnitude of these relationships increased with increasing sled loads. In conclusion, differences in speed, strength, and power abilities may explain, at least partially, the individual response of each athlete during sprinting towing a sled, especially with heavier sled loads. Thus, faster, stronger, and more powerful athletes require heavier sled loads (relative to %BM) to experience similar exercise intensities.

Ratanapinunchai, J and Madeeyoh, I. Differences in electromygraphic activity of the middle and the lower serratus anterior fibers during open and closed kinematics exercises. J Strength Cond Res 36(7): 1788–1792, 2022—This paper seeks to determine differences in muscle activation between the middle (MSA) and the lower serratus anterior (LSA) fibers during 3 exercises. Fifteen healthy men were recruited for the study. Bench push-up plus (BPUP), unstable BPUP (UPUP), and resisted shoulder flexion (RSF) with 10 repetitions at maximum weight were tested. The normalized electromyographic (EMG) activity of the MSA and the LSA was recorded during isometric scapular protraction for BPUP and UPUP or at 150° shoulder flexion for RSF. Normalization was calculated using maximum voluntary isometric scapular protraction activity (%EMG). The results showed that the ratio of %EMG of MSA:LSA was higher than one in BPUP (1.41 ± 0.36) and UPUP (1.81 ± 0.47), but less than one (0.86 ± 0.27) in RSF. These ratios were statistically significantly different (p < 0.05). The activity of MSA and LSA in RSF was significantly (p < 0.002) higher than that of BPUP and UPUP (%EMG of the MSA = 80.53 ± 26.07, 64.75 ± 23.19 and 55.62 ± 25.56 for the RSF, BPUP, and UPUP, respectively; %EMG of LSA = 95.54 ± 24.15, 50.71 ± 26.32, and 32.26 ± 16.14 for the RSF, BPUP, and UPUP, respectively). There was no difference in the %EMG of MSA and LSA between BPUP and UPUP. The MSA worked more than the LSA in the push-up plus (PUP), but the opposite was found in the RSF exercise. The study suggests different functions of the MSA and the LSA. Different exercises should be used, including a PUP for the MSA and RSF for the LSA, or a combination to emphasize both parts of the SA.

Authors: Ghaaowd Ismaail , Faisal Abu Hakim Muhammad Hasan , Rahman Md Habibur , Abu-Farsakh Murad
Published: August 2020

This study focused on evaluating the laboratory measurement errors and site variability due to soil deposition and operator using the following tests: unconsolidated-undrained (UU), Atterberg limits, small direct shear, and California bearing ratio (CBR) tests. Four clay soils with different plasticity indexes (PIs) were tested in the laboratory (PI = 11, 21, 38, 53), in addition to sandy soil and 3 aggregate base materials. Five different operators tested three specimens for each soil type to investigate the effect of operator on testing results. The maximum coefficient of variation (COV) data due to operator were 10.9 %, 7.8 %, 18.2 %, 16.9 %, 19.5 %, and 15.6 % for UU, liquid limit, plastic limit, plasticity index, direct shear, and CBR tests, respectively. The effect of operator and equipment on field testing results was evaluated using 28 cone penetration tests (CPTs) points performed in the same site at different times by two contractors. The spatial variability of CPT data was evaluated for each contactor and both combined. The values of COV for CPT data were different for the two contractors. The average COVs of pile design method and site variability were used to calibrate the Load Resistance Factor Design (LRFD) resistance factor, Φ, which showed high value for lower variability data, and vice versa for high variability data. The operator and equipment variabilities caused Φ to reach 0.24 for CPT data. In addition, the standard penetration test (SPT) and unconfined compressive strength test (qu) were collected from 21 borings and used to evaluate site variability. The value of Φ increased from 0.41, when COV of pile design method was only included, to 0.55, when site variability was included for SPT data. The same scenario was done for qu, in which Φ was increased from 0.34 when including COV of pile design method only to 0.39 when using the average COV of both method and site.
China’s Engagement with Former Foreign Leaders
Authors: Cooper Andrew F. , Wang Hongying
Published: August 2020

In recent years many former heads of foreign governments have visited China, appearing at various forums, conferences, and other events. China’s engagement with these former leaders may appear to be a form of public diplomacy, but even more importantly it has been a strategy of political legitimation adopted by the Chinese Communist Party. Based on an original database of hundreds of cases, we provide a systematic analysis of the visits of former foreign leaders to China and of their role as external validators for the party-state and its policy initiatives, particularly the Belt and Road Initiative. By shedding light on the Party’s search for external consent and support, we seek to fill a significant gap in the literature, which tends to focus narrowly on the domestic sources of legitimacy and domestic strategies of legitimation.
Han–Hui Relations and Chinese Regime Legitimation in the Xi Jinping Era
Authors: Stroup David R.
Published: August 2020

The Chinese Communist Party stresses the regime’s role in presiding over the unity of China’s minzu (ethnic groups) and their shared stake in China’s prosperity. However, an examination of the quality of interactions between Han and ethnic minorities illustrates the regime’s vulnerability to counterclaims based on these lived experiences. This paper conducts a case study of Han–Hui relations to argue that physical separation between Han and Hui prevents the two groups from interacting in ways that transmit substantive knowledge about the differences between the groups. Instead, interactions perpetuate stereotypes and distrust. By continuing to push narratives about the unity of all groups and shared family relations, the state highlights the shortcomings of its own policies, and undercuts its own legitimating narrative.
Stakeholder Attitudes and Factors Affecting Multiculturalism and Immigrant Integration Policy in South Korea
Authors: Lim Dong-Jin
Published: August 2020

This study analyzes the attitudes of core policy stakeholders in South Korea to multiculturalism and immigrant integration policies, as well as the factors affecting such attitudes, and suggests theoretical and policy implications. I conducted a survey of public officials, program operators, and academics. The responses suggest that public officials, program operators, and academics in Korea have more positive expectations for immigrants’ societal contributions and less fear of social clashes or conflicts due to increasing immigration, compared to the general public. They prefer the assimilationist model, which means that immigrants fully adopt the Korean culture and language as a matter of integration policy. The study sheds light on the stakeholders’ attitudes to multiculturalism and immigration integration policy, how their views differ from the general public, and the causes and policy implications of these differences.
Terrorism in Bangladesh
Authors: Lorch Jasmin
Published: August 2020

Bangladesh continues to face a threat from Islamic terrorism. However, the drivers of this phenomenon remain under-studied. Research has traced terrorism in Bangladesh to wider processes of Islamization; a political context marked by conflict between the country’s two main political parties and by authoritarian governance; the institutional weakness of the Bangladeshi security and justice system; and international factors, such as the Afghanistan War, influences from the Gulf, and more recently the Rohingya refugee crisis, as well as the increased interest of al-Qaeda and the Islamic State in South Asia. Based on an analysis of the literature and interviews, I argue that while the growth of terrorism in Bangladesh has been a complex process in which all of these factors have interacted, different constellations of them have been decisive at different historical stages.

To generate the full-length transcriptome of Xinjiang green and purple turnips, Brassica rapa var. Rapa, using single-molecule real-time (SMRT) sequencing. The samples of two varieties of Brassica rapa var. Rapa at five developmental stages were collected and combined to perform SMRT sequencing. Meanwhile, next generation sequencing was performed to correct SMRT sequencing data. A series of analyses were performed to investigate the transcript structure. Finally, the obtained transcripts were mapped to the genome of Brassica rapa ssp. pekinesis Chiifu to identify potential novel transcripts. For green turnip (F01), a total of 19.54 Gb clean data were obtained from 8 cells. The number of reads of insert (ROI) and full-length non-chimeric (FLNC) reads were 510,137 and 267,666. In addition, 82,640 consensus isoforms were obtained in the isoform sequences clustering, of which 69,480 were high-quality, and 13,160 low-quality sequences were corrected using Illumina RNA seq data. For purple turnip (F02), there were 20.41 Gb clean data, 552,829 ROIs, and 274,915 FLNC sequences. A total of 93,775 consensus isoforms were obtained, of which 78,798 were high-quality, and the 14,977 low-quality sequences were corrected. Following the removal of redundant sequences, there were 46,516 and 49,429 non-redundant transcripts for F01 and F02, respectively; 7,774 and 9,385 alternative splicing events were predicted for F01 and F02; 63,890 simple sequence repeats, 59,460 complete coding sequences, and 535 long-non coding RNAs were predicted. Moreover, 5,194 and 5,369 novel transcripts were identified by mapping to Brassica rapa ssp. pekinesis Chiifu. The obtained transcriptome data may improve turnip genome annotation and facilitate further study of the Brassica rapa var. Rapa genome and transcriptome.

Published: August 2020

Management consulting, as we know it today, has existed for over 100 years. We review the basic concepts of consulting, outline the major steps in the development of business-related consulting, and highlight that consulting plays an important role in shaping the globalization of multinational firms. Next, we depict the specific evolutionary steps of consulting in Czechoslovakia and independent Slovakia in the light of global and regional trends. The development of Slovakia is described within the framework of the first (1919-1939) and the second (1945-1992) Czechoslovak Republics, and we discuss the development of Marketing, HRM, and other consulting in Slovakia.  We also discuss clients' opinions of consultants in the light of an empirical research project carried out in 2018.
The interaction between Foreign Direct Investment and Domestic Investment: Is there crowding out effect?
Authors: Akin Tugba , Avcı Ozge Bolaman
Published: August 2020

After the fall of communism, Central and Eastern European countries have experienced a transition process in which a remarkable increase is observed in foreign direct investment flows into the region. During this process, when transition countries tried to adopt a free-market economy instead of a closed centrally structured economy, funds obtained through FDI constituted an essential way of financing for these countries that were trying to restructure their economy. Study questions the existence of the crowding-out effect by using data from Eastern European Countries, including Romania, the Russian Federation, Moldova, Poland, Bulgaria, Hungary, Slovak Republic, Ukraine. With this aim, PANIC Bai and Ng (2004), the bias-corrected PANIC Westerlund and Larsson (2009) unit root tests, and panel data analysis are implemented. Results obtained were consistent with theoretical expectations and showed that FDI had a crowding-out effect in the short run but, in the long run, a crowding-in impact on domestic investment.

Published: August 2020

The study aims to contribute to the medieval environmental history of the eastern periphery of the Transylvanian Plain (Câmpia Transilvaniei/Mezőség). With the help of archaeological and historical data and the multi-aspect analysis of undisturbed core sequences, the economic life of the Pauline Monastery founded in the 14th century near Sâncraiu de Mureş (Marosszentkirály) and the surrounding villages was investigated. The multidisciplinary research focuses on the paleochannels of the Mureş and the artificial watercourses (ditches) that branch off the river, and the mills built on them. The work also provides new data on the general environmental changes in the middle course of the Mureş river during the Middle Ages and the early modern period, which are largely due to the very intense human activity here.

Published: August 2020

Sample pretreatment is one of the most crucial and error-prone steps of an analytical procedure; it consents to improve selectivity and sensitivity by sample clean-up and pre-concentration. Nowadays, the arousing interest in greener and sustainable analytical chemistry has increased the development of microextraction techniques as alternative sample preparation procedures. In this review, we aimed to show two different categorizations of the most used micro-solid-phase extraction (μSPE) techniques. In essence, the first one concerns the solid-phase extraction (SPE) sorbent selection and structure: normal-phase, reversed-phase, ion-exchange, mixed-mode, molecular imprinted polymer, and special techniques (e.g., doped cartridges for specific analytes). The second is a grouping of the commercially available μSPE products in categories and sub-categories. We present every device and technology into the classifications paying attention to their historical development and the actual state of the art. So, this study aims to provide the state-of-the-art of μSPE techniques, highlighting their advantages, disadvantages, and possible future developments in sample pretreatment.
Environmental stress effects on appetite: Changing desire for high- and low-energy foods depends on the nature of the perceived threat
Authors: Swaffield Jim B. , Guo Qi
Published: August 2020

It is well-documented that harsh environmental conditions influence appetite and food choice. However, the experience of environmental harshness is complex and shaped by several underlying dimensions, notably threats to one's social support, economic prospects, and physical safety. Here, we examined the differential effects of these three dimensions of environmental harshness on desire for specific food items. We first showed 564 participants images of 30 food items. Next, they rated how much they desired each item. The participants were then randomly assigned to a condition where they read one of six scenario stories that described someone's current living conditions. Each scenario story emphasized one of the three dimensions (social support, economic prospects, physical safety), with two levels (safe, harsh). Following this, the participants once again rated how desirable each food item was. The results showed that exposure to cues of low social support and high physical threat reduce the desire to eat, whereas cues of economic harshness had little effect. Further analysis revealed a significant interaction between energy level of different foods and perceived threat to physical safety. These findings are important in helping to understand how current environmental conditions influence changes in appetite and desire for different kinds of food items.

Published: August 2020

The centenary celebration of the International Labour Organisation (ILO) is an ideal occasion to look at its current position, possibilities and challenges from the perspective of its long-lasting relation with the EU. This paper looks at the current state of affairs and how it has been achieved. It looks at the history of good cooperation of ILO and EU from the legal point of view highlighting some moments, when the ILO law has been ahead in social protection of workers, whilst showing that currently the EU is taking the lead in many fields. By commenting on recent basic documents of both the EU and ILO, the conclusion can be made that the solid and real interaction between both ‘legal systems’ can significantly contribute to more solidarity and decent work around the world.
