The Effect of Smartphones Usability on High School Students' Science Literacy Ability in Physics Learning
Authors: Putranta Himawan , Setiyatna Hery , Supahar Supahar , Rukiyati Rukiyati
Published: July 2021

Learning in high schools has used a lot of smartphone assistance to make it easier for students to understand the material explained by the teacher. However, with the many uses of smartphones in learning, of course, it must provide positive benefits to the ability of students, especially the science literacy ability. In this study, the objectives to be achieved are to examine how much the smartphone's usability in physics learning, examine students' science literacy and examine the effect of the smartphone’s usability on students' science literacy in physics learning. The method used in this study is a quantitative method with a research design used is a one-shot case study. The data on smartphone usability is obtained using a questionnaire, and science literacy of students is obtained through on physics science literacy test. The results of this study indicate that the smartphones usability and students' science literacy in physics learning are respectively in the high and medium categories with a respective percentage of 57.20% and 36.36%. The students' science literacy is influenced by the smartphone's usability in physics learning by 34.30%. These results indicate that smartphone usability by most students is very high, but has not been able to contribute optimally to students' science literacy. Therefore, special treatment is needed in utilizing the use of smartphones in physics learning so that students' science literacy can be optimized.
Understanding the Meaning of the Equal Sign: A Case Study of Middle School Students in the United Arab Emirates
Authors: Wardat Yousef , Jarrah Adeeb M. , Stoica George
Published: July 2021

The equal symbol has been used in diverse mathematical frameworks, such as arithmetic, algebra, trigonometry, set theory, and so on. In mathematical terms, the equal sign has been used in fixed command of standings. The study reports on the students meaning and interpretations of the equal sign. The study involved Grade 6, 7, and 8 students in a secondary school in Alain, United Arab Emirates (UAE). Much of the earlier research done on the equal sign has focused on the primary school level, but this one focuses on middle school students. The study shows that the maximum foremost understanding of the equal sign amongst Grade 6, 7, and 8 students is a do-something, unidirectional symbol. Students realize the equal sign as an instrument for marking the response moderately than as an interpersonal symbol to associate extents.
Covid19, intervención pública y preferencias redistributivas: un análisis descriptivo del caso español.
Authors: Ríos Fernández Mario , Valle Moreno Félix
Published: July 2021

La pandemia del COVID19 ha comportado grandes cambios en la sociedad. La fuerte intervención de los poderes públicos en la crisis sanitaria y el impacto social que esta ha provocado con el aumento de la pobreza y la desigualdad, son factores que pueden originar un conflicto social entorno a la redistribución de ingresos y de riqueza. El presente artículo pretende discernir desde un estudio del comportamiento de la opinión pública basándose en los Estudios de Opinión Pública y Políticas Fiscal del CIS si se ha producido un cambio en el apoyo al fortalecimiento del Estado de Bienestar, en cuestiones fiscales y en la prestación de servicios públicos y la capacidad de redistribución de las instituciones públicas.
Significado de Maternidad en usuarias feministas de Instagram en Lima Metropolitana
Authors: Velarde Russo Lucero Brenda
Published: July 2021

Introducción. En los últimos años el feminismo ha ocupado un espacio mayor dentro de la sociedad peruana. Por lo que se ha vuelto frecuente escuchar debates y opiniones diversas por parte de la población acerca de temas relacionados con este movimiento, siendo el «derecho a decidir ser madre o no» uno de los temas principales y tornando, de este modo, la maternidad en tema de discusión. Objetivo. Profundizar en el relato de las participantes para describir y conocer el significado de la maternidad en un grupo específico de mujeres, en este caso, feministas de tercera ola. Metodología. Estudio cualitativo fenomenológico. La técnica utilizada para la recolección de la información fue la entrevista individual semiestructurada. Se llevó a cabo en Lima, Perú. La muestra estuvo conformada por 7 participantes. Resultados y Discusión. Se identificaron tres categorías tras el análisis: (a) Sentidos de maternidad: concepción y experiencia frente a la maternidad; (b) Ser mujer: perspectiva propia y perspectiva de la sociedad; (c) Corporalidad: feminidad y experiencia emocional desde el cuerpo. Conclusiones. Las participantes concuerdan que el cuidado y cariño brindado al infante es lo que define el rol de madre, es decir, este rol deja de ser asignado únicamente al género femenino, dejando en el pasado la ecuación mujer igual madre, de este modo se amplían los horizontes del fenómeno y con ello se comprende la complejidad del mismo.

Authors: Ortiz-Contreras Jovita , Quiroz-Carreño Jael , Mella-Guzmán Maribel
Published: July 2021

Objetivo. Se pretende explorar el impacto de las inequidades de género en la salud sexual y reproductiva, con foco principal en la salud materna y perinatal. Método. Se realizó una revisión narrativa de categoría experto, orientada a la revisión temática con enfoque problematizador. Se llevó a cabo una búsqueda principal en las bases de datos Pubmed y Scielo, con una búsqueda secundaria en Google Scholar y adición por técnica de bola de nieve. Se llevó a cabo un análisis con relación a categorías de impacto, según dimensiones ex priori, y con base en un enfoque tipo hermenéutico interpretativo. Resultados. Del análisis se desprendieron cuatro categorías que dan cuenta de respuestas generales al objetivo de la revisión: garantías de derechos reproductivos; discriminación nutricional de género e impacto materno-perinatal; subvaloración social explícita e impacto perinatal; y violencia de género y riesgo reproductivo y perinatal. Conclusiones. La salud de las mujeres, así como su salud reproductiva, materna y perinatal, se encuentran permeadas por la condición de género, generando un impacto en el desarrollo pleno de los derechos sexuales y reproductivos, como al acceso a calidad de vida que propenda a mantener su potencial saludable. Por tanto, los indicadores que expresan la calidad de dicha salud requieren incorporación prioritaria de la transversalización de enfoque de género y derechos.
Hacia una nueva racionalidad política a partir de las relaciones sociedad-Estado
Authors: Balladares Burgos Jorge Antonio
Published: July 2021

Hoy en día se percibe una crisis en torno a las relaciones de la sociedad con el estado producto del descrédito por no sentirse identificados con el gobierno de turno, los actos de corrupción, la ineficacia de las acciones en torno a desastres naturales y humanos como la pandemia del Covid-19.  Esta realidad planetaria nos invita a pensar en una nueva racionalidad política que sea incluyente reconociendo las diferencias y diversidades del ciudadano común.  Para este cometido, el presente artículo realiza una revisión de la literatura desde un recorrido histórico desde diferentes autores de la filosofía política sobre los sentidos y las tensiones en las relaciones entre la sociedad y el estado.  Luego se plantea lo que es una nueva racionalidad política a partir de un sujeto político emergente que, ante las adversidades, las situaciones de marginalidad y pobreza, hace prevalecer el sentido de una conciencia colectiva.  Desde un enfoque hermenéutico, se realiza una definición de lo político, como una forma alternativa de la praxis política que busca recuperar el sentido de organización, convivencia y toma de decisiones desde nuestra condición como seres políticos.  De esta manera, las relaciones sociedad-estado serán resituadas para la búsqueda de un nuevo orden post-covid más justo, solidario, tolerante y resiliente.
Prácticas emergentes en proyectos de espacio público: el caso de vía Argentina en ciudad de Panamá
Authors: De Gracia José Antonio
Published: July 2021

This article uses an urban intervention in Panama City to discuss fundamental concepts in public space projects from a critical and theoretical perspective.First, the functions of the street as a basic structure of public space are illustrated. Its importance is recognized not only as an element of urban connectivity, but also as a place of movement, encounter, support and creation of urban meanings and social identities.Secondly, our case study is contextualized: the urban renewal of via Argentina, a street in the urban center whose environment was in a state of degradation like most streets in the city, largely occupied by the presence of vehicles. The intervention is part of a series of urban projects aimed at improving the physical structure of the city.The third section begins a critical analysis of the actions on Via Argentina, starting with the redistribution of street space, the relationship between vehicles and pedestrians, and the consolidation of public space.Next, we discuss in detail the new primary elements used for the urbanization of the street. Curbs, fords, pavement, rigola, gutters, tree surrounds and bollards become part of a system that must maintain a coherent relationship between all its parts. In addition, emphasis is placed on the design of the ground and the application of the pavement as a tool for the construction of an urban image and identity.Finally, the article ends with an analysis of the parameters of accessibility in the project, relating the concept to the use of the pavement and the configuration in some sections of the street as a single platform. The article uses a wide repertoire of documentary photography to contextualize the case study.
Optimization of the holographic wavefront sensor for open-loop adaptive optics under realistic turbulence. Part I: simulations
Authors: Zepp Andreas , Gladysz Szymon , Stein Karin , Osten Wolfgang
Published: July 2021

The modal holographic wavefront sensor enables fast measurement of
individual aberration modes without the need for time-consuming
calculations. However, the measurement accuracy suffers greatly from
intermodal crosstalk, caused when the wavefront contains more
aberrations than the one to be measured. In this paper, we present
sensor optimization to minimize this effect and show the improvement
when using Karhunen–Lòeve instead of Zernike modes as the basis.
Finally, we show in simulation that an open-loop adaptive optics
system based on the optimized sensor can be used to correct the effect
of realistic, dynamic atmospheric turbulence on a wavefront and
increase its Strehl ratio significantly.
High spectral purity microwave generation using a dual-frequency hybrid integrated semiconductor-dielectric waveguide laser
Authors: Mak Jesse , van Rees Albert , Lammerink Rob E. M. , Geskus Dimitri , Fan Youwen , van der Slot Peter J. M. , Roeloffzen Chris G. H. , Boller Klaus-J.
Published: July 2021

We present an integrated semiconductor-dielectric hybrid dual-frequency laser operating in the 1.5 μm wavelength range for microwave and terahertz (THz) generation. Generating a microwave beat frequency near 11 GHz, we observe an intrinsic linewidth as low as about 2 kHz. This is realized by hybrid integration of a single diode amplifier based on indium phosphide (InP) with a long, low-loss silicon nitride (Si3N4) feedback circuit to extend the cavity photon lifetime, resulting in a cavity optical roundtrip length of about 30 cm on a chip. Simultaneous lasing at two frequencies is enabled by introducing an external control parameter for balancing the feedback from two tunable, frequency-selective Vernier mirrors on the Si3N4 chip. Each frequency can be tuned with a wavelength coverage of about 80 nm, potentially allowing for the generation of a broad range of frequencies in the microwave range up to the THz range.
CAMBIO CLIMÁTICO Y RIESGOS EN EL ÁMBITO MEDITERRÁNEO. LA NECESIDAD DE ADAPTACIÓN
Authors: Olcina Cantos Jorge
Published: July 2021

El cambio climático es un proceso planetario que está manifestando efectos importantes en algunas regiones del mundo. La región mediterránea es un laboratorio privilegiado para el estudio del calentamiento de la atmósfera. Junto a la subida constante de la temperatura, registrada en las últimas décadas, el problema principal es el incremento en la frecuencia de desarrollo de eventos atmosféricos extremos que suponen un aumento del riesgo en el territorio. El territorio y las sociedades ibéricas deben adaptarse a los efectos del cambio climático. Las ciudades y las actividades económicas tienen que planificar su desarrollo futuro bajo los supuestos previstos en la modelización climática. Este es el reto más importante en la región mediterránea a lo largo del presente siglo.
Muchos Sócrates: Una introducción a las voces del círculo socrático
Authors: Illarraga Rodrigo , Lozano Nembrot Milena
Published: July 2021

En este artículo se busca presentar la pluralidad de voces en torno a la figura de Sócrates como problema filosófico. Un universo de críticas y encomios, diálogos constantes que se retroalimentan en respuestas y réplicas que podemos rastrear desde las mismas Acusaciones contra Sócrates de Polícrates y las respuestas de Jenofonte y Platón en sus sendas apologías. Es en esos intersticios en donde podemos reconstruir no solo a la figura de Sócrates, sino a la dinámica de su círculo, un grupo extenso y variopinto signado tanto por las diferencias entre sí como por la devoción a su amigo y maestro. Esta cuestión es, precisamente, la que atraviesa el dossier. Luego de una introducción al tema y, en especial, al rol de la obra de Jenofonte, se pasará a describir los artículos, mostrando los ejes en común que comparten.
Enseñar la sophrosyne: el uso del elenchos del Sócrates de Jenofonte
Authors: Danzig Gabriel
Published: July 2021

En contraste con la abundante discusión que podemos encontrar en torno a la representación realizada por Platón sobre el elenchos socrático, poco ha sido trabajado con respecto al elenchos tal como aparece en Jenofonte. La razón es obvia: Jenofonte hace un uso menor del elenchos que el que hace Platón y lo que el primero ofrece no es tan interesante filosóficamente. Sin embargo, hay buenas razones para mirar más de cerca al retrato hecho por Jenofonte; provee de una corrección al retrato excesivamente intelectualizante del elenchos que encontramos en los escritos de Platón, y exhibe una cualidad educativa que es característica de las actitudes de la antigua Grecia pero que no siempre es remarcada en los tratamientos de Sócrates. En la introducción a Badini y Dorion (2000-2010, cxviii-clxxxii), Louis-André Dorion ofrece un sagaz análisis del término elenchos tal como es usado por Jenofonte y un amplio estudio sobre los elenchoi en los escritos socráticos de Jenofonte. Aunque el Sócrates de Jenofonte usa a veces un tipo de argumentación que nos recuerda a su primo platónico, esto es solo una pequeña parte de su repertorio conversacional total. La educación no es alcanzada por medio de la interrogación sino gracias a la comunicación directa y abierta de la doctrina y a través de la práctica de la virtud (askēsis: ver Mem. I 2.23, ii 1.1). En lugar de emplear el elenchos, el Sócrates de Jenofonte generalmente pasa su tiempo ofreciendo un gran volumen de consejos útiles a sus amigos. De acuerdo con Dorion, el escaso uso por parte de Jenofonte del elenchos es el resultado de su profundo escepticismo sobre su valor educativo. Como resultado de este escepticismo, Jenofonte crea un retrato alternativo de Sócrates en el cual la interrogación desempeña un papel mucho más pequeño. Dorion está en lo cierto al notar que el elenchos es menos importante para Jenofonte que para Platón, pero su conclusión es un tanto extrema. Aunque Jenofonte no se concentra en el elenchos socrático, sí ofrece retratos de este sin por ello cuestionar en forma total el retrato del elenchos realizado por Platón. Esto es porque el elenchos tiene un cierto valor para Jenofonte, incluso si este valor difiere de aquel que podemos asumir que tiene en el retrato platónico. Como ha demostrado Morrison (1994), el elenchos cumple una valiosa función al seleccionar a los alumnos o prepararlos para lecciones aún más sustantivas. También puede desempeñar un valioso papel con relación al entrenamiento para y en la actuación en los asuntos políticos. Y el elenchos puede cumplir una función educativa en otro sentido, contribuyendo directamente con la adquisición de la virtud (sophrosune) por parte del interlocutor. Rastrearé estas funciones significantes para Jenofonte del elenchos.

Published: July 2021

Background and Aim: Salmonella is one of the most common foodborne pathogens, the emergence of antibiotic-resistant strains of which is increasing. The aim of this study was to phenotypically and genotypically characterize the fluoroquinolone resistance of Salmonella isolates from broiler and humans in two regions of Colombia.

Materials and Methods: Salmonella strains (n=49) were evaluated. The phenotype of antibiotic resistance was assessed by an automated method and agar diffusion method, as well as the presence of the quinolone resistance genes qnrA, qnrB, qnrC, qnrD, qnrS, and aac(6')-Ib as determined by polymerase chain reaction.

Results: Strains were resistant to ciprofloxacin (75%), levofloxacin (57.1%), and enrofloxacin (38.8%). Molecular identification showed that 24 out of 49 strains possessed the qnrB gene (48.9%), while only one isolate from the Santander region possessed the aac(6')-Ib gene. Regarding Class 1 integron, it was present in 11 out of the 49 strains (22.44%).

Conclusion: This study reports the presence of the gene qnrB as well the presence of Class 1 integrons in broiler Salmonella isolates, which may contribute to the resistance to fluoroquinolones.
DIVERSITY AND PHENETIC STUDY ON SYCONIUM OF FICUS L. (MORACEAE) FROM KERALA, INDIA REVEALING NATURAL CLASSIFICATION ALONG WITH AN IDENTIFICATION KEY
Authors: Nair Sreehari S , Bachan K.H. Amitha , Ebin P.J.
Published: July 2021

NAIR, S. S., BACHAN, K. H. A.  &  EBIN, P. J.  2021. Diversity and phenetic study on syconium of Ficus L. (Moraceae) from Kerala, India revealing natural classification along  with an identification key. Reinwardtia  20(1): 27–36. — Ficus L. commonly called ‘figs’ is one of the most complex genera among the angiosperms with its specialised inflorescence called syconium that looks like a fruit. Syconium of 33 species of  Ficus reported from Kerala were observed here to develop a novel key, solely based on syconium morphology. Numerical taxonomic methodology  for syconium  morphological characters  were standardised, considering 22 characters with 104 character states and analysed using similarity clustering. The floral features of the genus are very much complex and all the existing keys for the species identification relays on both vegetative as well as floral features. Hence, the present key will be practical  in  use  when  syconium  is  the  only  available  part.  The  numerical  analysis  of  the  syconium  features  well clustered and separated the trees with cauliflorous inflorescence, hemi epiphytic -epiphytic life forms and independent trees similar to the natural classification of the figs as  “Atthi, Itthi and Aal”, indicating that phenetic analysis using the syconium  characters  alone  provided  a  grouping  similar  to  the  natural  grouping  based  on  the  habit.  Preliminary phylogenetic analysis of figs also provided a similar clustering. This gives an insight into the fact that the separation of figs into these natural groups is reflecting phylogenetic trait. Detailed studies including more morphological traits and molecular analysis could establish the phylogenetic relation of figs in relation to the evolutionary history of climate and vegetation.
THE IMPACT OF FRAILTY ON POST-ACUTE REHABILITATION OUTCOMES IN OLDER ADULTS
Authors: ROMERO-ORTUNO R. , TIERNAN C. , COGAN L.
Published: July 2021

We assessed the correlations of the Frailty Instrument for primary care of the Survey of Health,Ageing and Retirement in Europe (SHARE-FI on admission: non-frail, pre-frail, frail) with the outcomes of aShort-term Post-Acute Rehabilitative Care programme (N=172 admissions over one-year period, 95 of whichwere frail). SHARE-FI correlated with age (non-frail: mean 79.2 years; frail: 83.6; P<0.001). Adjusting for age,SHARE-FI correlated with longer length of stay (non-frail: median 30 days; frail: 42; P=0.047), higher rate ofemergency transfer to acute hospital (non-frail: 2.4%; frail: 21.1%; P=0.004), and lower home discharge rate(non-frail: 97.6%; frail: 81.9%; P=0.009). While frailty correlated with more disability on admission anddischarge, there was no statistically significant difference in Barthel Index (BI) improvement across frailtycategories (all groups had median BI improvement of ≥2 points, P=0.247). The post-acute rehabilitation of thefrail is worthwhile but requires more time and access to acute hospital facilities.
A Pragmatic Comparison of Four Different Programming Languages
Authors: Ali Saqib , Qayyum Sammar
Published: July 2021

Programming language debates are extremely common among programmers, computer science students and of course, software engineers. However, all of the above-mentioned professionals can concur that different languages excel in different scenarios. Software Engineers and programmers working on different projects can easily use different languages for different tasks during their work. Every year different programming languages are designed and created. In this Research, we will keep in focus the Four Horsemen of programming languages: C, C++, Python and Java; with respect to the criteria of time, speed and simplicity. The same optimized piece of pseudocode is used to write the code of the different programming languages mentioned above by following their respective syntax and rules. The results of the comparison will be displayed with the help of a table in order to simplify the final results for the reader.
Developing an Angled Perspective as Teacher Educators: Using Narrative Reflection to Disrupt the Funding of Identity in Teacher Education
Authors: Aronson Brittany , Enright Esther , Amatullah Tasneem
Published: July 2021

Building capacity in teachers to teach students skillfully and respectfully across the diversity gap is complex work that requires teachers to learn to see with what we term as angled perspective. If an angled perspective is learnable, then it is teachable. Using our narratives as religiously and ethnically diverse women teacher educators, we share through our own learning and growth, how this type of analysis can contribute to coalitional building for teacher education, and thus K-12 teachers. Through our conceptualization of identity theory, positionality, and intersectionality, we argue angled perspectives contribute to solidarity work in education. We share implications for teacher educators to integrate angled perspectives into curricula across teacher preparation courses.
La gubernamentalidad de la seguridad a través de laprevención situacional ambiental de delito. El caso de Rosario (1995-2016)
Authors: Ginga Luciana Noelia
Published: July 2021

El presente artículo tiene el objetivo de analizar la gubernamentalidad de la seguridad, a partir de la prevención del delito como un prolífero dispositivo de intervención en Rosario desde 1995 hasta 2016. Nos proponemos por un lado, describir las iniciativas gubernamentales públicas destinadas a modificar y mejorar situaciones y/o ambientes urbanos para reducir las oportunidades de comisión de actos delictivos, en el intento de gestar un espacio público «seguro»; y por el otro, identificar las iniciativas de prevención del delito que parten desde los/as ciudadanos/as intentando encontrar los modos en los que se involucran en el propio gobierno de sí mismos/as. Nuestro propósito, entonces, está focalizado en reconstruir el dispositivo de gobierno a través de la lógica preventiva. La sofisticación de las tecnologías de gobierno son especialmente atractivas para nuestro estudio y, en este sentido, consideramos vital concentrarnos en ellas ofreciendo un análisis que permita recomponer un mapa posible —no único ni unívoco— de combinaciones e hilvanado de la matriz discursiva y extradiscursiva del arte neoliberal de gobernar desde la experiencia local. Este artículo está basado en el análisis de documentos oficiales, de la prensa local y entrevistas semi-estructuradas a un/a funcionario/a municipal y a informante clave e integrante de organizaciones de la Sociedad Civil quienes se han desempeñado en áreas afines a nuestro tema de investigación.
El nacimiento de los cuerpos naranjas. La emergencia de la Policía Comunitaria de Santa Fe como programa de gobierno policial
Authors: Truchet Rocio
Published: July 2021

El presente artículo tiene como objetivo analizar las condiciones políticas que dieron lugar a la emergencia de la Policía Comunitaria en la Provincia de Santa Fe durante el año 2014. Desde la perspectiva foucaultiana de la gubernamentalidad, entendemos que este segmento especializado se conforma como efecto de disputas políticas destinadas a definir la policía en tanto locus central en el campo de gobierno de la (in)seguridad. El trabajo adopta una metodología cualitativa y aplica el análisis crítico del discurso en un corpus constituido a partir de documentos oficiales, fuentes periodísticas y entrevistas a informantes clave. Con estos discursos políticos procuramos identificar la tematización securitaria y la función policial construidas en el devenir de la Policía Comunitaria, como así también, las estrategias y técnicas que dicha unidad pretendió movilizar para intervenir en el campo de la (in)seguridad. Concluimos que la creación de esta nueva fuerza puede ser leída como un programa de gobierno de la Policía de Santa Fe enmarcada en el paradigma de la Seguridad Democrática.

Authors: Mafudi Innal , Handhika Jeffry
Published: July 2021

The purpose of this research is to describe the use of assisted virtual laboratories of Electronic Workbench (EWB) in physics experiments learning. The method in this study used (1) calibration of the results of experiments with theory and (2) analysis of user responses to EWB in practicum activities. The study concluded that: 1) EWB is easy to use for practical learning, 2) capacitive reactance values obtained from calculations and observations following the theory (close to the same), 3) the time needed for one-time trial data retrieval until the analysis phase in this practicum activity is 10 minutes means that the experiment with EWB is very efficient. Based on the results obtained indicate that EWB is feasible to use as an alternative to physics learning in the mass pandemic COVID-19.
Desposesión y violencia. Un problema para volver a pensar lo humano en bioética
Authors: Moscoso Cala Javier
Published: July 2021

La vulnerabilidad es un tema central en bioética. Cómo sea comprendida tiene claras consecuencias en las relaciones entre paciente, personal médico y personal investigador. Las reflexiones acerca de la vulnerabilidad de Judith Butler ponen de manifiesto que asentar la protección de la violencia en una noción de vulnerabilidad restringida a la exposición al daño, la enfermedad y la muerte ignora la dependencia fundamental que la vulnerabilidad implica. La reformulación compleja de la vulnerabilidad que propone Judith Butler posibilita desplazar el foco de la protección de la integridad personal hacia la demanda de la minimización social de la violencia.

Impact of Climate Change on Sea Surface Temperature and Chlorophyll-a Concentration in South Sukabumi Waters
Authors: Suhermat Mamat , Dimyati Muhammad , Supriatna S. , Martono M.
Published: July 2021

Indonesia territorial waters are very vulnerable to the impacts of climate change. Research about the variations of sea surface temperature and chlorophyll-a concentration in the southern waters of Java has been undertaken by several researchers. However, the research is still in the scope of regional scale south of Java. This research was conducted to determine the impact of climate change on sea surface temperature and chlorophyll-a concentration in Sukabumi waters. The data used consisted of IOD index anomalies, sea surface temperature and monthly chlorophyll-a concentrations from December 2002 to November 2020. Descriptive analysis was used to determine seasonal and inter-annual variability and linear regression method was used to analyze trends in changes in sea surface temperature (SST) and chlorophyll-a concentration. The results showed that the seasonal variation was influenced by the monsoon, while the interannual variation was influenced by the Indian Ocean Dipole. Climate change causes SST and chlorophyll-a concentrations to increase. In the 2003-2020 time period, SPL increased by 0.08 °C and an increase in chlorophyll-a concentration by 0.03 mg/ m3. ABSTRAKPerairan selatan Sukabumi yang berhadapan langsung dengan samudera Hindia sangat rentan terhadap dampak perubahan iklim. Penelitian mengenai variasi suhu permukaan laut dan konsentrasi klorofil-a di perairan selatan Jawa sudah dilakukan oleh beberapa peneliti sebelumnya. Namun penelitian tersebut masih dalam lingkup skala regional selatan Jawa. Penelitian ini dilakukan untuk mengetahui dampak perubahan iklim terhadap suhu permukaan laut dan konsentrasi klorofil-a di Perairan selatan Sukabumi. Data-data yang digunakan terdiri dari indeks IOD, suhu permukaan laut dan konsentrasi klorofil-a bulanan periode Desember 2002 hingga November 2020. Metode yang digunakan dalam penelitian ini adalah analisis deskripsi dan regresi linier. Hasil penelitian menunjukkan bahwa variasi musiman suhu permukaan laut dan konsentrasi klorofil-a di perairan ini dipengaruhi oleh monsun, sedangkan variasi antar tahunan dipengaruhi oleh Indian Ocean Dipole. Perubahan iklim menyebabkan suhu permukaan laut dan konsentrasi klorofil-a mengalami kenaikan. Dalam periode waktu 2003-2020 suhu permukaan laut mengalami kenaikan sebesar 0,08°C dan kenaikan konsentrasi klorofil-a sebesar 0,03 mg/m3.
Inscribed rectangle coincidences
Authors: Schwartz Richard Evan
Published: July 2021

We prove an integral formula for continuous paths of rectangles inscribed in a piecewise smooth loop. We use this integral formula to prove the inequality M(γ) ≥ Δ(γ)/2 – 1, where M(γ) denotes the total multiplicity of rectangle coincidences, i.e. pairs, triples, etc. of isometric rectangles inscribed in γ, and Δ(γ) denotes the number of stable diameters of γ, i.e. critical points of the distance function on γ.
On the alethic and moral status of political storytelling
Authors: Klenner Niels , Köppe Tilmann
Published: July 2021

The article reconstructs the theory of political storytelling as outlined by political strategist Mark McKinnon. Stories that conform to this theory feature a suspense structure, and as such they invoke hope and fear in recipients, thereby instilling pro- or contra-attitudes. This is potentially problematic in four respects: Political storytelling (1) can be used to induce attitude-change without a rational foundation, thereby infringing on the receiver’s right to epistemic self-determination; (2) political storytelling may involve a misrepresentation of the teller’s communicative intentions, thereby disclosing the truth about them in a way that is potentially harmful to society; (3) by expressing rather than stating crucial elements of his or her “message,” the political storyteller may immunize him- or herself from critique and mask the true content of the message; (4) by attempting to influence recipients’ preferences, the political storyteller does not conform to some fundamental principle of representative democracy.
Unnatural narratives, Brexit and ideology in Ian McEwan’sThe Cockroach
Authors: Zhang Dandan
Published: July 2021

Against the backdrop of sudden shifts in global political and historical climate, our century has witnessed a convergence of turns in humanities, including the nonhuman turn and the historical turn. Ian McEwan’s latest novella,The Cockroach, is a just work along this line. Through the use of unnatural narratives within realistic context, McEwan presents readers with a world that is both strange and recognisable. By examining the unnatural narrative strategies, including the deployment of nonhuman character and omniscient narrator, McEwan expresses concerns for the future of humanity and fear for social and cultural parochialism, populism and anti-cosmopolitanism.
The Legal Characterization of Crypto-Exchange Platforms
Authors: Minto Andrea
Published: July 2021

In a thriving crypto-assets market, crypto exchange platforms play a pivotal role. Indeed, such trading systems are instrumental to the matching of demand and supply (trading) as well as the transfer of tokens (settlement and post-trading). Yet, there is currently no bespoke regulatory framework applicable to crypto exchange, raising pressing questions on whether and how those platforms are regulated. This article examines the Italian regulatory framework applicable to crypto-exchange platforms. It shows that the present regulatory engagement with crypto exchanges relates to the qualification of the crypto assets traded. Depending on such qualification, different financial regimes could be triggered.
Freie mündliche Interaktion – Eine kriteriengeleitete Lehrwerkanalyse von drei Grundstufenlehrwerken des Niveaus A2: Studio d, Optimal und Schritte international
Authors: Suresh Indira
Published: July 2021

Mit der kriteriengeleiteten Lehrwerkanalyse betritt dieser Beitrag bekanntes Terrain: Kriterien für die Beurteilung von Lehrwerken zu formulieren hat im Fach Tradition. Die Analyse von drei A2-Lehrwerken zeigt, dass Aufgabenformate zur freien mündlichen Interaktion oft nicht angemessen vorbereitet werden. Bei Lernenden sind Überforderung und daraus resultierende Sprechhemmungen zu beobachten, denn viele Aufgabenformate sind nur unzureichend in kleinschrittige Sequenzen unterteilt. Die Lehrkraft muss die Schwachstellen der Lehrwerke daher durch Ergänzungsübungen kompensieren.

Der Aufbau einer zentrale Servicestelle für Forschungsdatenmanagement (FDM) an einer Hochschule ist ein mehrjähriger Prozess, der in die Phasen Initiation, Gründung, Aufbau und Roll-out und Verstetigung unterteilt werden kann. Die vorliegende Roadmap führt durch die einzelnen Abschnitte und beleuchtet dabei Herausforderungen und Umsetzungsschritte anhand gesammelter Erfahrungen an der Universitätsbibliothek (UB) Duisburg-Essen. Als zentrale Bausteine des Konzepts für die „Research Data Services“ werden das entwickelte Dienstleistungsportfolio vorgestellt, das die verschiedenen Handlungsfelder des FDM abdeckt, als auch die organisatorische Struktur, die alle relevanten Akteure innerhalb und außerhalb der Hochschule einschließt. Die Verschränkung von Fachwissenschaft und FDM ist wichtige Gelingensbedingung der Etablierung von Services und wird an der UDE insbesondere durch die enge Zusammenarbeit mit Forschungsverbünden erreicht.
Extract the information from big data with randomly distributed noise

Published: July 2021

In this manuscript, a purely data-driven statistical regularization method is proposed for extracting the information from big data with randomly distributed noise.
Since the variance of the noise may be large, the method can be regarded as a general data preprocessing method in ill-posed problems, which is able to overcome the difficulty that the traditional regularization method is unable to solve, and has superior advantage in computing efficiency.
The unique solvability of the method is proved, and a number of conditions are given to characterize the solution.
The regularization parameter strategy is discussed, and the rigorous upper bound estimation of the confidence interval of the error in the

Published: July 2021

Digital technologies have been at the heart of fieldwork at the Kaymakçı Archaeological Project (KAP) since its beginning in 2014. All data on this excavation are born-digital, from textual, photographic, and videographic descriptions of contexts and objects in a database and excavation journals to 2D plans and profiles as well as 3D volumetric recording of contexts. The integration of structure from motion (SfM) modeling and its various products has had an especially strong impact on how project participants interact with the archaeological record during and after excavation. While this technology opens up many new possibilities for data recording, analysis, and presentation, it can also present challenges when the requirements of the recording system come into conflict with an archaeologist’s training and experience. Here, we consider the benefits and costs of KAP’s volumetric recording system. We explore the ways that recording protocols for image-based modeling change how archaeologists see and manage excavation areas and how the products of this recording system are revolutionizing our interaction with the (digital) archaeological record. We also share some preliminary plans for how we intend to expand this work in the future.
Are persistent aircraft trails a threat to the environment and health?
Authors: Deruelle Fabien
Published: July 2021

According to most scientific studies, media and governments, the white trails that can be seen behind aircraft in flight, corresponding to condensation mixed with engine particulate emissions, only persist under specific atmospheric conditions. They are called condensation trails, and cirrus contrails when they remain for hours to reach several kilometers wide. The fact that they have gradually filled the skies over the last twenty years would be due to the increase in air traffic. However, other official documents link these persistent trails to a weather modification technology called solar geoengineering by stratospheric aerosol injection (SAI). These sprays would be mainly composed of metallic particles (Al, Ba, Sr, Fe, nanoparticles) and sulfur, which would considerably increase air, soil and water pollution. Many of the current environmental and health problems are consistent with those described in the literature on solar geoengineering by SAI if this method was employed. For example, metal particles used are well known environmental contaminants, ozone layer depletion, cardiorespiratory diseases, neurodegenerative diseases, sunburn. The observations (whiter skies, less solar power) also correspond to the same risks as those described in the solar geoengineering works. Patents show that this weather modification technology has been known and mastered for a long time. In addition, some scientific papers as well as policy documents suggest that solar geoengineering by SAI has been used for many years. The amount of official information presented in this review is intended to open new ways of investigation, free of conflicts of interest, about the growing global pollution of persistent aircraft trails and their possible links with solar geoengineering by SAI.

Published: July 2021

Organic-inorganic lead halide perovskite solar cells have rapidly emerged as a newfangled material for solar energy harnessing. Perovskite solar cells have succeeded in gaining a power conversion efficiency of 25% in the last year, further enhancement in the efficiency is anticipated due to advanced engineering of the different components making up the complete cell architecture with enhanced performance, stability and efficiency. Significant components of perovskite solar cell configurational architecture are the electron transport layer, active perovskite absorber layer, hole transport layer and counter electrode. Considering the profound role of transport layers in charge mobility, current review has particularly elucidated the advancements in the charge transport layers. The time duration of the review is from 2010 to 2021. However, the special focus has been laid on the recent articles. The influence of different organic and inorganic materials used for development of transport layers influencing the cell performance have been summarized. Materials used for transport layers have been modified by utilization of myriad of engineered substances through doping and surface functionalization strategies but every method have been marked by posing serious challenges towards the stability and efficiency of the cell and thus, hindering its commercialization. The review also provides an elucidation of the mechanical challenges and abatement strategies. These strategies are associated with the charge transport layers for enhancement of cell functionality.
Nation als gefühlte Gemeinschaft
Authors: Voigt Katrin
Published: July 2021

Ausgehend von Sara Ahmeds Beobachtung, dass die Bekundung nationaler Scham ein Idealbild der Nation als gefühlte Gemeinschaft konstruiert, untersucht der Artikel die Bedeutung der Emotion Scham in einer Interviewstudie zum Thema nationale Identität mit deutschen Staatsbürger*innen im Kontext der Fußballweltmeisterstaft der Männer 2018. Dabei wird deutlich, dass das Thema nationale Scham innerhalb des Samples auf vielfältige Weise verhandelt wird und bei einigen Interviewten starke Ambivalenzen auslöst. Der Artikel arbeitet unterschiedliche Mechanismen heraus, die zur Überwindung dieser Ambivalenzen von den Interviewten angewendet werden – insbesondere das Konstrukt der gesellschaftlichen Mitte und die Inszenierung eines unpolitischen Raumes im Fußball – und untersucht kritisch deren Funktion hinsichtlich von Distinktionsgewinnen innerhalb der Nation wie auch nach außen.
Optimization of a circumferential groove in a centrifugal compressor

Published: July 2021

In this work, a circumferential groove on the shroud was applied to a centrifugal compressor and optimized to improve the stability of the compressor. To reduce the number of design variables before optimization, the position of the casing groove that maximizes the stall margin of the compressor was firstly selected. The width and height of the casing groove were optimized using the RSM (Response Surface Method) and the full factorial design of experiments to increase the stall margin further. It was observed that the optimized case with the casing groove can increase the stall margin by 7.0% but the adiabatic efficiency at the design condition decreases by 0.99%, in comparison to the reference case without the groove. Finally, the flow field of both cases with and without the optimized casing groove was compared to each other to analyze effects of the casing groove on the stall margin and design efficiency. The casing groove decreases the leakage flow across the impeller tip and weakens the tip leakage vortex, consequently decreasing the blockage near the shroud and improving the stall margin. However, it was found that the spillage of the flow from the casing groove increases the mixing loss near the shroud.

In this paper, Sn-doped TiO2 nanomaterials with varying concentrations were manufactured through a simple procedure. The fabricated TiO2 and Sn loaded on TiO2 nanoparticles were studied using X-ray diffraction, scanning electron microscopy, transmission electron microscopy, energy dispersive X-rays, Fourier transform infrared spectroscopy, and resistance analyses. The benefits of dielectric constant and ac conductivity rise at high Sn loaded concentration on TiO2 nanoparticles. The enhanced electrical conductivity is seen for STO3 (3.5% Sn doped TiO2) and STO4 (5% Sn doped TiO2) specimens are apparently associated with the introduced high defect TiO2 lattice. Furthermore, the fabricated specimens’ obtained findings may be applied as possible candidates for high-energy storage devices. Moreover, proper for the manufacture of materials working at a higher frequency.

Authors:   Cruz Roja Española, Narváez María del Carmen , Arredondo Rafael
Published: July 2021

The present study tries to analyze the variables influencing school dropout and failure, focusing on a specific population with the highest risk, minors expelled from schools. For this, the data collected during five school years (2014-15 to 2018-19) has been taken, through an initial questionnaire carried out in the Civic Association for Prevention (ACP), within the Project for Attention to Minors in Expulsion (PAMEX), to a total of 523 minors. It can be observed in the results obtained the determination of a profile that characterizes these students, mostly boys of the first cycle of secondary education, with similar hobbies and enjoyment of free time, as well as the consumption of addictive substances, highlighting the importance of abuse of energy drinks. This longitudinal study has made it possible to compare these variables over time and how they have been maintained. Future lines of research and intervention are also proposed after the confinement suffered by minors due to COVID-19, focused on mitigating variables such as resilience and engagement.
