Published: March 2021

Adult separation anxiety disorder (ASAD) is characterized by developmentally inappropriate and excessive fear or anxiety concerning separation from those to whom the individual is attached. Despite the high rates of this diagnosis among Portuguese adults, there is a lack of measures to assess it. In this study, we assessed the psychometric properties of a Portuguese adaptation of the Adult Separation Anxiety questionnaire (ASA-27) on a sample of 267 adults (72.7% women) aged 18–80 years (M= 40.5,SD= 13.1). Factor structure, internal consistency, and convergence validity were examined. This study confirmed the single-factor structure of the Portuguese version of ASA-27. Consistency was high for the total sample (ω = .92) and by gender (ω = .93 and 92, men and women groups, respectively). The scale was positively related to the Portuguese version of State-Trait Anxiety Inventory (STAI) (r= .57,p< .001, for both State and trait anxiety scales) and Composite Codependency Scale total score (r= .29,p< .001). In addition, the ASA-27 total score showed incremental validity in the explanation of anxiety measured by STAI. In conclusion, results show that the Portuguese version of the ASA-27 is a reliable and valid measure of ASAD.

Published: March 2021

Eco-cities have witnessed rapid growth in these years worldwide. As the Eco-cities entering operation stage gradually, more and more researchers have found that users (who are living or working in the Eco-cities) satisfaction is one of the most important factors to determine the success or failure of Eco-cities. Therefore, it is very important to investigate the user demands to attract more citizens willing to live or work in the Eco-cities, which will make the development of Eco-cities more sustainable and solid. The recent researches on user demands investigation and analysis in the Eco-cities mainly focused on understanding the user need itself, yet lack of research on the relationship between the user demand and user satisfaction. This paper initially introduced the Kano model analysis method to the research field of user demands in Eco-city, to explore the relationship between the user demand and user satisfaction. After proposing user demands library in Eco-city (including Land use, Ecological environment, Green building, Energy utilization, etc.), the user demands classification and importance analysis methods of Eco-city were proposed based on Kano model. The questionnaire survey for users of two Eco-cities in China as case study was conducted, consisted of user demand items questionnaire based on the Kano model and a questionnaire on the importance of the user demand items. By utilizing the integration of quantitative analysis methods based on the Kano model and Analytic Hierarchy Process (AHP) method, the final ranking of user demands importance was obtained. Comparing with the existing literatures in terms of user demands research for Eco-city, the user demands analysis method based on Kano model of this paper, is able to reveal the influence degree of user satisfaction towards the facilities and services provided in the Eco-city. The user demands analysis method can be used for other researchers worldwide to investigate and quantitively analyze user demands according to their local development situation and preference of Eco-city. The user demands analysis results obtained through this method, can benefit different stages of Eco-city.

Low oxygen and mechanical loading may play roles in regulating the fibrocartilaginous phenotype of the human inner meniscus, but their combination in engineered tissues remains unstudied. Here, we investigated how continuous low oxygen (“hypoxia”) combined with dynamic compression would affect the fibrocartilaginous “inner meniscus-like” matrix-forming phenotype of human meniscus fibrochondrocytes (MFCs) in a porous type I collagen scaffold. Freshly-seeded MFC scaffolds were cultured for 4 weeks in either 3 or 20% O2or pre-cultured for 2 weeks in 3% O2and then dynamically compressed for 2 weeks (10% strain, 1 Hz, 1 h/day, 5 days/week), all with or without TGF-β3 supplementation. TGF-β3 supplementation was found necessary to induce matrix formation by MFCs in the collagen scaffold regardless of oxygen tension and application of the dynamic compression loading regime. Neither hypoxia under static culture nor hypoxia combined with dynamic compression had significant effects on expression of specific protein and mRNA markers for the fibrocartilaginous matrix-forming phenotype. Mechanical properties significantly increased over the two-week loading period but were not different between static and dynamic-loaded tissues after the loading period. These findings indicate that 3% O2applied immediately after scaffold seeding and dynamic compression to 10% strain do not affect the fibrocartilaginous matrix-forming phenotype of human MFCs in this type I collagen scaffold. It is possible that a delayed hypoxia treatment and an optimized pre-culture period and loading regime combination would have led to different outcomes.

A non-neoplastic epithelium (NE) often appears in gastric cancer (GC). We explored the histological features of NE in comparison between HP-eradicated and HP-infected GCs. We enrolled 40 HP-eradicated and 40 HP-infected GCs matched by size, macroscopic and histological type. NE was classified into full gland type and surface type; the former was a non-neoplastic gland isolated within cancer, and the latter was NE on the surface of the cancer. Surface type was additionally divided into NE at the cancer margin (marginal surface type) and NE inside cancer (internal surface type). The primary endpoints were the frequency and the length ratio (the ratio to cancer length) of NE. The secondary endpoints were the relationships between NE and clinicopathological factors, including endoscopic findings of a gastritis-like appearance (GLA), reddish depressed lesion (RDL), and white nodular mucosa (WNM). The frequency and length ratio of the internal surface type in HP-eradicated GCs were significantly higher (82.5% vs 50%, P = 0.005) and larger (11.6 ± 10.6 vs 4.2 ± 9.9, P < 0.001) than those in HP-infected GCs, and the increase was more significant according to the passage of time since HP eradication. The frequency and length ratio of marginal surface type and full gland type were not significantly different between the two groups, but the coexistence of internal surface and full gland types was statistically significant (p < 0.001). The frequencies of GLA, RDLs, and WNM in HP-eradicated GCs were significantly higher than those in HP-infected GCs. GLA-positive GCs were covered more widely by internal surface type than GLA-negative GCs (13.3% vs. 6.6%, P = 0.003). Various types of NE were noted in gastric cancer, and the internal surface type of NE was shown to be significantly linked to HP-eradicated cancer and GLA.

A csomagolás részét képezi a jelölés – vagy más néven címke, label –, aminek elsődleges funkciója a termék tulajdonságairól való tájékoztatás, amellett, hogy a vállalat és a fogyasztó egyik legfontosabb találkozási pontja. Kiemelt szerepe van a marketing és a vállalati menedzsment eszköztárában, hiszen a fogyasztói döntéshozatal meghatározó forrása. A szerző írásában a jelölések definícióját, fajtáit és csoportosítását tárja az olvasó elé, majd ismerteti jelentőségét, fontosságát és szerepét az élelmiszer-ipari termékek segítségével. Ezután egy 630 fős megkérdezés eredményeképp a sokdimenziós skálázás (MDS) módszerével a jelölések új értelmezését mutatja be: a jelöléseket három dimenzió mentén lehet elhelyezni (előzetes tudás, érdek, megbízhatóság), valamint ezenkívül a jelölések öt homogén csoportot alkotnak (klasszikus, diétás, funkcionális, tudatos, előállítási). A téma jelentőségét az egészség és a környezet iránti növekvő érdeklődés, valamint a változó jogszabályi környezet is alátámasztja. / === / Signs, labels, claims are to inform consumers of product attributes, and are part of the packaging. Labeling is one of the most important marketing and management tool, while purchase decision is made at the point of purchase. The aim of this paper is to present the basic definitions and elements of information content on food packaging. The author developed a new approach to examine labeling using multidimensional scaling as a result of a pilot study. Labels are to distinguish through three dimensions: precognition, interest and reliability. Beyond that labels can be sorted to five homogeneous clusters based on classic, dietary, functional, conscious and production attributes. The relevancy of labeling is supported by growing interest of health and environmental issues and changing law environment.

Published: March 2021

This article provides extant background on online learning including best practice frameworks at multiple educational levels. The authors also discuss important considerations of remote and online learning when one is planning or teaching in that modality. Perhaps most importantly, this piece details the account of one highly qualified teacher’s experience transitioning to remote learning during the spring of the COVID-19 pandemic, which can serve as an exemplar to others. This example will demonstrate how teachers can be effective when mandated to utilize remote or hybrid teaching. The piece will also share implications for the future of teaching and teacher preparation.
COVID-19 Modifications to a Service-Learning Project Designed to Prepare Special Education Students to Be Effective Participants in Transdisciplinary Collaborations
Authors: Doody Kathy , Fulcher Katrina , Schueltze Pamela
Published: March 2021

This research study examined the impact of COVID-19 on university students’ perceptions about the effectiveness of a community-based service-learning project designed to prepare graduate students in special education and undergraduate students in psychology and speech-language pathology to work in transdisciplinary teams in early childhood settings. Students were placed into transdisciplinary teams and assigned to one of two community-based early childhood programs to administer a universal screening tool that assessed young children in several domains. The project was in its sixth year when the country stood still because of the COVID-19 pandemic. The project was re-envisioned, mid-course, to provide an equitable and rigorous assignment for students who were unable to complete the original assignment due to the lockdown. Student perceptions were compared, pre and post COVID; subsequent results are discussed in alignment with the original four goals of the project. Additionally, suggestions are posed to position this service-learning assignment for remote delivery should the pandemic persist to disrupt higher education.
Effect of Sand Percentage on the Compaction Properties and Undrained Shear Strength of Low Plasticity Clay
Authors: Alkroosh Iyad , Al-Robay Ali , Sarker Prabir , Alzabeebee Saif
Published: March 2021

This paper investigates the influence of sand content on the mechanical behavior of a low plasticity clay that collected from south of Iraq (Sumer town). Samples have been prepared with sand contents of 0%, 10%, 20%, 30%, and 40% of the clay weight. Standard Proctor and unconfined compression tests have been carried out and the optimum moisture content, maximum dry density, and undrained shear strength have been determined. The results show a gradual increasing trend of the maximum dry density with the increase of the sand content up to 30%. The highest dry density reaches 1.90 g/cm3 corresponding to an optimum moisture content of 12%. In addition, this paper shows that the undrained shear strength is inversely proportional to the increase of the percentage of sand. The results of this work provide a useful addition to the literature regarding the behaviour or low plasticity clay-sand mixture.
La psicología educativa a debate en nuestro país: de una encrucijada a algunas alternativas de solución.
Authors: León Cascón José A.
Published: March 2021

Desde sus inicios, la figura del psicólogo educativo en nuestro país y especialmente en lo referente a su ejercicio profesional, ha estado sometido a los dictámenes de las diferentes leyes que han regulado el sistema educativo español basadas en criterios muy diferentes y que abarcan desde la Ley General de Educación hasta la LOE y, la más reciente, la LOMCE. En el momento actual nos encontramos con serios problemas y dilemas con los que se enfrenta nuestra profesión y la formación psicológica especializada. Estos problemas afectan directamente al desajuste entre la formación profesional del psicólogo educativo y su adecuación a las demandas del mercado de trabajo, muchas de ellas inespecíficas o aglutinadas bajo un paraguas de orientación educativa. Por otro, los problemas afectan a diversos modelos de formación, a veces con objetivos opuestos, desarrollados a través de un master en psicología educativa. En este artículo se abordarán dichos problemas junto con algunas de las iniciativas que desde organizaciones avaladas por el COP han tenido lugar en los últimos años y que tratan de responder a los principales desafíos relacionados con la formación, los procesos de acreditación y el rol del psicólogo en el sistema educativo español, así como los criterios de convergencia que se están buscando en Europa entre asociaciones profesionales como la EFPA.

Authors: Pineda David , Valiente Rosa María , Martínez-Martínez Ana , Chorot Paloma , Sandín Bonifacio
Published: March 2021

La evidencia reciente indica que la psicopatología del niño está determinada por múltiples factores, tanto personales como familiares y sociales. Entre los factores familiares cabe destacar la influencia de las prácticas de crianza de los progenitores. Sin embargo, la relación entre las prácticas educativas de los padres y los síntomas de ansiedad y depresión de los niños, en función de sexo de los padres ha sido menos estudiada. Los objetivos de esta investigación han sido examinar la relación entre las prácticas educativas parentales y los síntomas interiorizados de los niños, así como las posibles diferencias en función del sexo de los progenitores; un segundo objetivo ha sido explorar el papel que la edad y el sexo de los niños pueden desempeñar en estas relaciones. Estas cuestiones fueron examinadas en una muestra por conveniencia de 211 niños con edades comprendidas entre los 8 y los 12 años. En general, los resultados obtenidos apoyan la hipótesis de las diferencias en función del sexo de los progenitores. Se discuten los resultados encontrados en base a la literatura existente y se proponen algunos aspectos que debería abordar la investigación futura.

Authors: Arnau Víctor Manuel , Checa Esquiva Irene , Bohórquez Gómez-Millán M. Rocío
Published: March 2021

El objetivo de este trabajo fue explorar la influencia que el género, la edad, los años nadando y la resiliencia tienen sobre la ansiedad competitiva en una muestra de nadadores escolares (N=74). La resiliencia fue medida con una adaptación española del CD-RISC, mientras que para medir la ansiedad competitiva se utilizó la versión española del CSAI-2R. También se exploraron los datos sociodemográficos (edad, sexo, años nadando y nivel competitivo). Para el análisis de datos se realizaron pruebas no paramétricas (Kruskal-Wallis y U de Mann Whitney), además de correlación de Pearson. Los resultados mostraron que el género, la edad de los nadadores y los años nadando no guardan relación con los niveles de ansiedad competitiva de los nadadores en edad escolar evaluados, mientras que el grado de resiliencia mostró una relación positiva con los niveles de autoconfianza, una relación negativa con los niveles de ansiedad cognitiva, y ninguna relación con la ansiedad somática. Estos resultados demuestran que el entrenamiento en la resiliencia de los jóvenes nadadores puede reducir sus niveles de ansiedad y mejorar su experiencia deportiva.

Published: March 2021

El objetivo de este estudio es analizar si la condición de trabajo emocional, TE, y estresores laborales, EL, predicen la ansiedad y depresión en un grupo de profesores universitarios mexicanos; además de analizar si las sub-escalas del TE, el sexo y la edad contribuyen para explicar dichos síntomas. Se ha señalado una estrecha relación entre estresores, ansiedad y depresión en la docencia, sin embargo, esto no ha ocurrido tan claramente con el trabajo emocional. 211 profesores universitarios de escuelas públicas participaron. Los modelos de predicción simple muestran que la ansiedad y la depresión son explicados por el TE y EL. El modelo de predicción múltiple muestra que, ser mujer, el TE y los EL contribuyen para explicar sólo la ansiedad. Este estudio permite identificar variables de predicción de salud mental en profesores universitarios mexicanos, pero aún es necesario profundizar acerca de la contribución del TE sobre la salud mental.

Published: March 2021

El periodo postparto es una etapa vital que supone retos importantes para muchas familias y que puede generar dificultades en el ámbito relacional e íntimo de las parejas, incluyendo la sexualidad. A pesar de ello, la atención que se presta desde los servicios de salud pública tiende a centrarse en la diada madre-hijo y en los cuidados al bebé, omitiendo esta importante parcela de intervención. Existe, por lo tanto, una necesidad real de ofrecer a las parejas recursos que les permitan afrontar este periodo y convertirse en un marco de seguridad afectiva para el desarrollo mutuo y del recién nacido. Se describe en este trabajo una intervención, desde psicología clínica, dirigida a parejas en el puerperio cuyo objetivo es la posible prevención de disfunciones sexuales, problemas de pareja y dificultades en el crecimiento psicoafectivo de los niños. Este tratamiento grupal incluye: abordaje y discusión de mitos, desarrollo de una comunicación eficiente en la pareja, fortalecimiento de la autoestima, información sobre la sexualidad e identificación de las dificultades en la pareja en esta fase, subrayando el papel del padre en el desarrollo del bebé. Por último, se concluye la importancia de una intervención psicológica en parejas en la etapa del postparto.

Published: March 2021

Objetivos: El presente trabajo tuvo como objetivo describir la representación de la enfermedad en pacientes con un trastorno de la conducta alimentaria (TCA) y evaluar su relación con el ajuste psicosocial y el malestar psicológico, siguiendo el Modelo de Auto-Regulación de Leventhal. Método: Participaron 56 pacientes diagnosticados de un TCA, que estaban siendo atendidos en una unidad especializada y en un centro de Atención Primaria, y cumplimentaron el BIPQ, el PAIS-SR, el HADS y el GHQ-12. Resultados: Los pacientes percibieron que su enfermedad tenía consecuencias serias para su vida y que el tratamiento ayudaría a mejorar su condición. Consideraron que el trastorno tenía emociones negativas asociadas, además de poseer una percepción de escaso control personal sobre el problema. La percepción de consecuencias y la representación emocional se asociaron con un peor ajuste psicosocial y con el malestar psicológico. Sin embargo, la percepción de control personal se relacionó con un mejor ajuste psicosocial y emocional. Conclusiones: Los hallazgos de este trabajo señalan la importancia de considerar las cogniciones individuales de estos pacientes sobre su enfermedad, con el fin de intervenir desde el tratamiento sobre estas creencias para mejorar el ajuste y disminuir las repercusiones emocionales negativas.

Published: March 2021

Los trastornos alimentarios no solo afectan a la persona que los sufre sino también a sus familiares. La literatura señala que es frecuente que los familiares de estas pacientes presenten una elevada percepción de carga, malestar emocional y acomodación al síntoma. Estas variables se han relacionado con el pronóstico y evolución de estas pacientes. El objetivo del presente trabajo fue evaluar y describir la acomodación a la enfermedad, la percepción de carga y el malestar emocional en 93 familiares de pacientes diagnosticados con un trastorno alimentario, así como analizar las relaciones entre estas variables. Los resultados mostraron diferencias significativas entre hombres y mujeres en la percepción de carga, la acomodación y el malestar emocional, presentando las familiares mujeres mayores puntuaciones en estas variables. Estas variables presentaron relaciones positivas y significativas entre ellas. El aislamiento social predijo un 46.5% de la varianza del malestar emocional de los cuidadores. Estos resultados sugieren la importancia de apoyar a los familiares y diseñar intervenciones específicas para ellos.
Incoherencias en la práctica de la entrevista motivacional
Authors: Moreno Arnedillo José Javier
Published: March 2021

El interés, la formación y la práctica de la entrevista motivacional en el ámbito de las adicciones han experimentado un desarrollo espectacular en las últimas décadas. Este impulso, sin duda positivo, convive, no obstante, con conceptos con los que es incoherente. Por un lado, con la visión del comportamiento adictivo como irracional o patológico (modelo de enfermedad más o menos ‘cerebral’); por otro, con una visión de la motivación como estado interno de naturaleza cognitiva previo a la acción., fuertemente vinculada a la popularización del modelo de las ‘fases’ del cambio. Frente a este planteamiento, la estrategia de la validación, como elemento central y definitorio de la entrevista motivacional, requiere asumir la racionalidad del comportamiento adictivo y de las resistencias a su abandono, así como el carácter contextual y no internalista de la disposición al cambio. En particular, se cuestiona el modelo de las ‘fases’ y se defiende una visión de la disposición al cambio no como previa y causante de la acción, sino como resultado de la relación entre la acción y sus resultados, señalando sus implicaciones para la práctica clínica.

Published: March 2021

El objetivo del estudio era conocer la relación entre las diferentes dimensiones de la variable de personalidad de búsqueda de sensaciones y algunas conductas de riesgo, concretamente el consumo de drogas y la conducta sexual de riesgo, en función del género de los participantes. Asimismo, se estudió si los consumos de las diferentes drogas y la conducta sexual de riesgo estaban relacionados entre sí. La muestra contó con 367 participantes de Ecuador (un 55.6% de chicos y un 44.4% de chicas) de entre 13 y 17 años. Se administraron algunos ítems de la escala The Adolescent Risk-Taking Questionnaire y la escala Sensation-Seeking Scale-V. Los resultados mostraron que la búsqueda de experiencias y la desinhibición son las dos dimensiones que mejor explican las conductas de consumo en ambos géneros y que estos explican la conducta sexual de riesgo en chicos pero no en chicas. Además, se encontró que el consumo de drogas y las conductas sexuales de riesgo presentaron relación en ambos casos. Se plantea así la necesidad de buscar alternativas para que aquellos jóvenes con más necesidad de experimentación canalicen esa característica hacia actividades saludables.

Published: March 2021

La obesidad es uno de los problemas de salud actuales más relevantes. La literatura científica señala la relación de la obesidad y la actividad física respecto a variables psicológicas. Además, la adultez emergente es un periodo vital en el que existe un abandono de hábitos saludables. En las últimas décadas se ha observado una ganancia de peso en este periodo. Por tanto, el objetivo de este trabajo fue analizar el papel de la actividad física en adultos emergentes con obesidad y su influencia en variables psicológicas, así como establecer un perfil de variables psicológicas respecto al sobrepeso y la obesidad en relación con personas con normopeso. La muestra estuvo formada por 118 estudiantes universitarios, de los cuales 59 presentaban normopeso (IMC medio=21.66, DT=3.26; 76.3% mujeres) y 59, sobrepeso y obesidad (IMC medio=27.83, DT=2.50; 67.8% mujeres). Se emplearon diversas medidas de alexitimia, regulación emocional, ansiedad y depresión, autoestima y conducta alimentaria. Únicamente se encontraron diferencias entre las personas con normopeso y obesidad en autoestima. En las diferencias en el grupo de sobrepeso a partir del nivel de actividad física, se observó peor ajuste psicológico en quienes realizaban más actividad física. Finalmente, se discuten las implicaciones de estos hallazgos.

Las técnicas empleadas fueron: psicoeducación, técnicas de la entrevista motivacional, auto-registros, modelado, entrenamiento en respuesta alternativa, control estimular, solución de problemas, reestructuración cognitiva, control de la respiración y exposición. La intervención se llevó a cabo durante 20 sesiones, distribuidas semanalmente. A partir de un análisis cualitativo y cuantitativo de la evolución de la paciente, se puede concluir que el tratamiento fue eficaz, y los retos de la intervención son discutidos.
Cytotoxic Activity of Ethyl-para-methoxycinnamate from Kaempferia galanga L. on A549 Lung Cancer and B16 Melanoma Cancer Cells
Authors: Apriani Riza , Abdullah Fajar Fauzi
Published: March 2021

Kaempferia galanga L. belongs to the family of Zingiberaceae, an endangered medicinal plant with pharmacology activities. Ethyl-p-methoxycinnamate (EPMC) is an essential phytoconstituent of K. galanga rhizomes. Several studies have reported that EPMC has anticancer activities in several cancer cells, including CL-6 gallbladder cancer cells, HepG2liver cancer cells, MCF-7 breast cancer cells, and Raji lymphoma cancer cells. However, studies on A549 lung cancer and B16 melanoma cancer cells have not been reported. This study aimed to determine the anticancer activity of EPMC against A549 lung cancer and B16 melanoma cancer cells. EPMC was obtained by extraction using n-hexane, then recrystallized with chloroform. The isolate was then analyzed by thin-layer chromatography (TLC), and the structure was characterized by Fourier Transform Infrared (FTIR) and Nuclear Magnetic Resonance (NMR) spectroscopy. Cytotoxic activity was determined under Presto Blue assay. Based on the result, EPMC from K. galanga showed the cytotoxic effect on B16 cells with an IC50 value of 97.09 μg/mL, whereas EPMC showed no significant cytotoxic effect on A549 with an IC50 value of 1407.75 μg/mL. It was concluded that EPMC has potential cytotoxic on B16 melanoma cancer cells, but it showed inactive activity against A549 lung cancer cells. Further molecular mechanism underlying EPMC cytotoxic activity needs to be conducted.

Published: March 2021

Red fruit oil contains carotene, which is dark orange, so it is not very popular. Therefore, it is necessary to reduce the intensity of the color. Yesterday, in this study, the synthesis and characterization of Al-pillared clay (Al-PILC) from light and heavy clay fractions were carried out. The absorption capacity of red fruit carotene dyes was studied. The research stages included preparation, fractionation, activation, pillarization of clay with aluminum, characterization, and adsorption test for carotene dyes on red fruit. Characterization was carried out using X-ray Diffractometer (XRD) and Gas Sorption Analyzer (GSA). The results showed that basal spacing of natural clay, Al pillared heavy fraction-clay, Al pillared light fraction-clay, activated light fraction were 15.08 Å, 15.27 Å, 16.84 Å, and 16, respectively. 22 Å. The GSA results showed that the surface area and pore volume of the Al pillared light fraction-clay of 0.3 was higher than the heavy fraction. The average pore size of Al pillared light fraction-clay and the heavy fraction was found in the mesoporous range of 30-100 Å, and the adsorption isotherm is type IV. Al-pillared light fraction-clay had higher adsorption ability than a heavy fraction and light fraction before pillaring. When the pillaring agent’s concentration was 0.3 M, Al pillared heavy fraction-has absorption capacity is 58.66%, while Al pillared light fraction-clay is 90.4%.
Pricing influential nodes in online social networks
Authors: Zhu Yuqing , Tang Jing , Tang Xueyan
Published: March 2021

Influential nodes with rich connections in online social networks (OSNs) are of great values to initiate marketing campaigns. However, the potential influence spread that can be generated by these influential nodes is hidden behind the structures of OSNs, which are often held by OSN providers and unavailable to advertisers for privacy concerns. A social advertising model known as influencer marketing is to have OSN providers offer and price candidate nodes for advertisers to purchase for seeding marketing campaigns. In this setting, a reasonable price profile for the candidate nodes should effectively reflect the expected influence gain they can bring in a marketing campaign.

In this paper, we study the problem of pricing the influential nodes based on their expected influence spread to help advertisers select the initiators of marketing campaigns without the knowledge of OSN structures. We design a function characterizing the divergence between the price and the expected influence of the initiator sets. We formulate the problem to minimize the divergence and derive an optimal price profile. An advanced algorithm is developed to estimate the price profile with accuracy guarantees. Experiments with real OSN datasets show that our pricing algorithm can significantly outperform other baselines.
Fast incremental discovery of pointwise order dependencies
Authors: Tan Zijing , Ran Ai , Ma Shuai , Qin Sheng
Published: March 2021

Pointwise order dependencies (PODs) are dependencies that specify ordering semantics on attributes of tuples. POD discovery refers to the process of identifying the set Σ of valid and minimal PODs on a given data set
D.
In practice
D
is typically large and keeps changing, and it is prohibitively expensive to compute Σ from scratch every time. In this paper, we make a first effort to study the incremental POD discovery problem, aiming at computing changes ΔΣ to Σ such that Σ ⊕ ΔΣ is the set of valid and minimal PODs on
D
with a set Δ
D
of tuple insertion updates. (1) We first propose a novel indexing technique for inputs Σ and
D.
We give algorithms to build and choose indexes for Σ and
D
, and to update indexes in response to Δ
D.
We show that POD violations
w.r.t.
Σ incurred by Δ
D
can be efficiently identified by leveraging the proposed indexes, with a cost dependent on
log
(|
D
|). (2) We then present an effective algorithm for computing ΔΣ, based on Σ and identified violations caused by Δ
D.
The PODs in Σ that become invalid on
D
+ Δ
D
are efficiently detected with the proposed indexes, and further new valid PODs on
D
+ Δ
D
are identified by refining those invalid PODs in Σ on
D

The problem of mining integrity constraints from data has been extensively studied over the past two decades for commonly used types of constraints, including the classic Functional Dependencies (FDs) and the more general Denial Constraints (DCs). In this paper, we investigate the problem of mining from data approximate DCs, that is, DCs that are "almost" satisfied. Approximation allows us to discover more accurate constraints in inconsistent databases and detect rules that are generally correct but may have a few exceptions. It also allows to avoid overfitting and obtain constraints that are more general, more natural, and less contrived. We introduce the algorithm ADCMiner for mining approximate DCs. An important feature of this algorithm is that it does not assume any specific approximation function for DCs, but rather allows for arbitrary approximation functions that satisfy some natural axioms that we define in the paper. We also show how our algorithm can be combined with sampling to return highly accurate results considerably faster.
Sharing opportunities for OLTP workloads in different isolation levels

Published: March 2021

OLTP applications are usually executed by a high number of clients in parallel and are typically faced with high throughput demand as well as a constraint latency requirement for individual statements. Interestingly, OLTP workloads are often read-heavy and comprise similar query patterns, which provides a potential to share work of statements belonging to different transactions. Consequently, OLAP techniques for sharing work have started to be applied also to OLTP workloads, lately.

In this paper, we present an approach for merging read statements within interactively submitted multi-statement transactions consisting of reads and writes. We first define a formal framework for merging transactions running under a given isolation level and provide insights into a prototypical implementation of merging within a commercial database system. In our experimental evaluation, we show that, depending on the isolation level, the load in the system and the read-share of the workload, an improvement of the transaction throughput by up to a factor of 2.5X is possible without compromising the transactional semantics.

Current systems for data-parallel, incremental processing and view maintenance over high-rate streams isolate the execution of independent queries. This creates unwanted redundancy and overhead in the presence of concurrent incrementally maintained queries: each query must independently maintain the same indexed state over the same input streams, and new queries must build this state from scratch before they can begin to emit their first results.

This paper introduces
shared arrangements
: indexed views of maintained state that allow concurrent queries to reuse the same in-memory state without compromising data-parallel performance and scaling. We implement shared arrangements in a modern stream processor and show order-of-magnitude improvements in query response time and resource consumption for incremental, interactive queries against high-throughput streams, while also significantly improving performance in other domains including business analytics, graph processing, and program analysis.

Published: March 2021

Although prior research on late-career entrepreneurship has explored the effects of financial, human, and social capital on the intentions to engage in entrepreneurial activity within the domains of a developed economy, little research has investigated this scholarship in the context of a push perspective within a developing economy. This study endeavors to meet this gap by investigating the effects of financial, social, and human capital and the personal dispositional traits on the entrepreneurial intentions among early retirees in the ICT sector of Pakistan. Based on the collected data from the web-based questionnaire and personally administered surveys and interviews from 345 respondents who face a survival challenge in the aftermath of a job loss, we make use of hierarchical logistic regression to periodically explore the independent and combined effects of the financial, social and human capital and the impact of a stable dispositional trait of fear of failure on the entrepreneurial intention. Being one of the foremost studies to address the late-career entrepreneurship phenomenon in a developing economy, this study has to offer notable contributions to entrepreneurship literature. Consistent with prior research, we observe support for the individual influence of various elements of financial, social, and human capital and the fear of failure on the intentions to engage in an entrepreneurial career. Results also demonstrate considerable evidence for the interaction effects among financial, human, and social capital as well as among different measures of financial capital, human capital, and the fear of failure. Discussion about the results is furnished followed by limitations and future research implications.

The integration of geophysical techniques with hydrological investigation is frequently used for solving different geological and environmental problems including groundwater quality and exploration and seismic vulnerability assessment. In this research, the shallow geophysical techniques comprising of electrical resistivity profiling, vertical electrical sounding, and ground magnetic were used to identify the contaminated areas lying in the upstream and downstream of Almisk Lake in Jeddah. The chemical analyses of water samples collected from the wells located in the downstream and upstream areas were used to support these results as an increase in the total dissolved solids (TDS) shows a decrease in the resistivity value. The results of geophysical techniques and hydrochemical analyses show that the TDS values are significantly higher in the upstream area of dam than those of the downstream, which suggests that the contaminating source is lying in the upstream of the reservoir. Moreover, the dam was not completely successful to block the contamination because of improper base. The hydrochemical analysis and geophysical results clearly indicate that the groundwater is not suitable for drinking and irrigation purposes.
Teaching South African Sign Language as a second language to university students: an integrated pedagogy
Authors: Stander Marga , Le Roux Annemarie
Published: March 2021

South African Sign Language (SASL) has become an increasingly popular language that hearing university students want to learn as a second language. This requires more qualified SASL instructors and new curricula at South African universities. This paper considers ways in which challenges associated with the teaching and learning of SASL can be overcome. Krashen’s Comprehension Input Hypothesis and Swain’s Output Hypothesis form the theoretical framework as reference to our own independent experience, praxis, and reflection. This study considered different teaching methods and pedagogies and found the post-method approach suggested by Kumaravadivelu (2003) a viable method for teaching SASL as a second language. This method aligns with the method we had independently identified as the most empowering for teachers to create their own strategies focused on their intuition, experiences and pedagogy. Therefore, we do not favour one specific method above another, but rather adopt an integrated approach. We make a few suggestions regarding sign language curriculum content and further research in sign language as an L2, which need urgent attention.
Kant on Traveling Blacksmiths and Passive Citizenship
Authors: Moran Kate A.
Published: March 2021

Kant makes and elaborates upon a distinction between active citizenship and passive citizenship. Active citizens enjoy the right to vote and rights of political participation generally. Passive citizens do not, though they still enjoy the protection of the law as citizens. Kant’s examples have left commentators puzzling over how these distinctions follow from his stated rationale or justification for active citizenship, namely, that active citizens possess a kind of political and economic self-sufficiency. This essay focuses on one subset passive citizenry – that of traveling blacksmiths, barbers, and day laborers in order to examine Kant’s distinctions. I argue that these examples show that Kant’s concerns regarding dependence are, at least in some cases, pragmatic rather than political.
Horaz ins Stammbuch geschrieben – Ein neu aufgefundenes Kant-Autograph
Authors: Walter Martin
Published: March 2021

Recently (2019/20), a new autograph written by Immanuel Kant in October 1786 was found and identified. It is a quotation from Horace’s Epistles I. 1, 60 dedicated to Johann Friedrich Lange (1760–1826), a preacher and former student of Kant’s at the Albertina University: “Let this be a man’s brazen wall (rule of life), to be conscious of no ill, to turn pale with no guilt.” Kant quoted the passage several times; one time in his MS. Horace was one of Kant’s favorite Latin poets.

Background

Kawasaki disease (KD) is a systemic inflammatory condition occurring predominantly in children. Coronary artery bypass grafting (CABG) is performed in the presence of inflammation and aneurysms of the coronary arteries. The objectives of our study were to assess which CABG strategy provides better graft patency and early and long-term outcomes.

Methods

A systematic review using Medline, Cochrane, and Scopus databases was performed in February 2020, incorporating a network meta-analysis, performed by random-effect model within a Bayesian framework, and pooled prevalence of adverse outcomes. Hazard ratios (HR) and corresponding 95% credible intervals (CI) were calculated by Markov chain Monte Carlo methods.

Results

Among 581 published reports, 32 studies were selected, including 1,191 patients undergoing CABG for KD. Graft patency of internal thoracic arteries (ITAs), saphenous veins (SV), and other arteries (gastroepiploic artery and radial artery) was compared. ITAs demonstrated the best patency rates at long-term follow-up (HR 0.33, 95% CI: 0.17–0.66). Pooled prevalence of early mortality after CABG was 0.28% (95% CI: 0.00–0.73%, I
2 = 0%, tau2 = 0), with 63/1,108 and 56/1,108 patients, undergoing interventional procedures and surgical re-interventions during follow-up, respectively. Pooled prevalence was 3.97% (95% CI: 1.91–6.02%, I
2 = 60%, tau2 = 0.0008) for interventional procedures and 3.47% (95% CI: 2.26–4.68%, I
2 = 5%, tau2 <0.0001) for surgical re-interventions. Patients treated with arterial, venous, and mixed (arterial plus second venous graft) CABG were compared to assess long-term mortality. Mixed CABG (HR 0.03, 95% CI: 0.00–0.30) and arterial CABG (HR 0.13, 95% CI: 0.00–1.78) showed reduced long-term mortality compared with venous CABG.

Conclusions

CABG in KD is a safe procedure. The use of arterial conduits provides better patency rates and lower mortality at long-term follow-up.
