Sensory cue, emotion, cognition and impulse buying behaviour of fast-food vendors in Ghana
Authors: Martey Edward Markwei , Martey Racheal Markwei , Adenutsi Kingsford 
Published: January 2021

Fast food vendors use a sensory cue to trigger impulsive buying behaviour. Though impulse buying has gained interestamong researchers, little has been done concerning food in Ghana. The purpose of the study was to investigate thecontribution of the sensory cue on customer’s emotions and cognition and impulsive buying behaviour. The study findsanswers to the succeeding research questions: what sensory cue impacts on consumer emotion and cognition? And doesemotion and cognition influence consumer’s impulsive buying behaviour. A proposed theoretical model identifies visual,audio, and tactile dimensions as the sensory cue, emotions, and cognitive as mediation variable and impulsive buyingbehaviour as the outcome. Data were collected from 241 customers who were residence in Tema and have patronizedthe services of food vendors for a minimum of two years using a convenience sampling technique. The suggestedhypothesis was tested using structural equation modeling and hierarchical multiple regression analysis. The result of thestudy shows that visual, audio, and tactile dimensions have a positive relationship with emotion but a negativerelationship with cognition. Regarding directs effect, the study revealed that there is a positive relationship betweenemotion and impulsive buying behaviour whiles cognition has a negative effect on impulsive buying behaviour. Thestudy recommended that managers must induce impulsive buying using characteristics of the food they serve and theenvironments in which they operate to stimulate customers' arousal and pleasure and provide enough information toalleviate the risk customers consider before buying food. The findings may not be generalized since the data wascollected in specific areas in Tema.

Toma de decisión para colocar mantenedor de espacio después de la pérdida prematura de primeros molares primarios: Revisión de literatura
Authors: Pino Guerrero Elizabeth Fiorella , Castillo Cevallos Jorge Luis 
Published: January 2021

Introducción: La pérdida prematura de molares primarios ha sido asociada con la perdida de espacio y dificultades eruptivas. Sin embargo, existen opiniones diferentes sobre la necesidad de colocar mantenedor de espacio después de la pérdida prematura de un primer molar primario. El propósito de esta revisión es proporcionar un resumen de la evidencia disponible respecto a la colocación de mantenedor de espacio después de la perdida prematura del primer molar primario.
Métodos: Se realizó una revisión de literatura en base de datos electrónicas desde el año 1977 hasta el 2016, en las bases de datos (Pubmed, Medline, EBSCO).
Resultados: La mayor parte de estudios concluyeron que la mayor pérdida de espacio ocurre después de la perdida prematura de un primer molar primario mandibular. Muchos factores condicionan está perdida, como lo son la falta de espacio disponible, el status de erupción del primer molar permanente, el momento de la perdida prematura, entre otros.
Conclusiones: Según los estudios consultados la magnitud de la pérdida de espacio después de la pérdida prematura de un primer molar primario es clínicamente cuestionable, no tiene un gran efecto en los arcos dentales. Sin embargo se ha demostrado un gran efecto en el sitio de extracción por lo cual el mantenedor de espacio debe ser usado lo más temprano posible para evitar el desplazamiento de los dientes adyacentes. Cabe resaltar que el tamaño de las muestras y la metodología de algunos artículos son limitadas, por lo cual se requiere estudios de mejor calidad metodológica.
Propuesta metodológica para el análisis gráfico, tipográfico y cromático de cartelería
Authors: Tabuenca Bengoa María , González-Díez Laura , Puebla Martínez Belén 
Published: January 2021

No existe un consenso claro en cuanto al método más apropiado para el estudio de carteles, por lo que se han ido utilizando unas y otras alternativas al hilo de las necesidades puntuales de cada investigación.
El objetivo del presente artículo es plantear una propuesta metodológica para análisis del diseño gráfico de cartelería, y la elección de dicha temática viene dada por la ausencia de una metodología clara a este respecto y se justifica por la escasez de modelos previos que versen sobre el análisis del cartel.
La presente propuesta tiene como fin abordar y plantear un diseño de fichas de variables con el que poder extraer posteriormente en el trabajo de campo, no solo elementos descriptivos cualitativos de los carteles, si no datos cuantitativos del objeto de estudio en cuestión.
En un primer momento se hace necesario plantear una ficha más genérica, para posteriormente abordar la carga textual y del contenido icónico del cartel en sus correspondientes plantillas, para en una última examinar la propuesta cromática, tanto de los elementos tipográficos como de los gráficos.
Para el diseño de dichas tablas de análisis se tendrán en cuenta, en primer lugar, los datos informativos básicos sobre de los carteles, para una vez definidos los criterios compositivos elementales, pasar a examinar pormenorizadamente, en posteriores plantillas, las distintas creaciones artísticas, definidas por los citados contenidos textual, gráfico y cromático.
Large-Scale Production of Basic Commodities at Salinas de los Nueve Cerros, Guatemala
Authors: Woodfill Brent K. S. 
Published: January 2021

Salinas de los Nueve Cerros is a major Pre-Columbian Maya city that grew around the only non-coastal salt source in the Maya lowlands. Residents of the city were able to transform the neighborhoods adjacent to and atop the salt dome into a large-scale production operation with the capacity to produce over 10,000 metric tons of salt a year, which were then distributed throughout the western lowlands via the Chixoy, Pasión, and Usumacinta river networks. By the Late Classic period, the city had expanded into the production and trade of other commodities that were locally produced (including agricultural and pescacultural goods) and traded from farther upriver. Investigations at Nueve Cerros since 2010 have shown that the salt source and basic production was tightly controlled by the local elite—workshops were associated with administrative structures containing the tombs of important individuals—although some phases of production or refining appear to have taken place throughout the site in each of the different neighborhoods under investigation.

Srovnávací studie právních informačních systémů: rozdíly mezi systémy při využití různých vyhledávacích strategií
Authors: Harašta Jakub 
Published: January 2021

Vyhledávání právních informací v právních informačních systémech je běžnou součástí života právníka. V zásadě je možné ve dvou modech: jako vyhledávání zprostředkované a nezprostředkované. V rámci zprostředkovaného vyhledávání se spoléháme na souvislosti připravené tvůrcem systému. Jedná se například o přiřazení dokumentu do oblasti úpravy nebo, na specifičtější úrovni, o označení soudních rozhodnutí jako souvisejících s určitým předpisem nebo ustanovením. Při nezprostředkovaném vyhledávání se uživatel naopak spoléhá sám na sebe. Sám formuluje plnotextové dotazy a vyhledává výrazy, které pro něj symbolizují rešeršovaný problém. V tomto textu se zaměřuji na porovnání výsledků poskytnutých právními informačními systémy ASPI, Beck-online a Codexis v odpovědi na srovnatelné dotazy využívající zprostředkovaných i nezprostředkovaných právních informací. Po úvodu a přehledu literatury následuje představení výzkumných otázek. Čtvrtá část pak popisuje metodu použitou pro srovnání systémů a data k tomuto srovnání využitá. Pátá část popisuje výsledky srovnání napříč právními informačními systémy ASPI, Beck-online a Codexis. Šestá část se věnuje diskuzi těchto výsledků a jejich zasazení do kontextu. V poslední části pak předkládám závěr a formuluji doporučení ohledně volby vyhledávacích strategií při sběru právních informací (dokumentů) pro akademickou i praktickou činnost. Závěrem tohoto textu je, že při využití různých systémů pro zprostředkované vyhledávání (identifikaci soudních rozhodnutí souvisejících s konkrétním ustanovením) pozorujeme výrazné rozdíly. Naopak při zařazení metod nezprostředkovaného vyhledávání (plnotextový dotaz) jsou si výsledky poskytnuté jednotlivými systémy podobnější, byť jsou celkově horší oproti vyhledávání zprostředkovanému.
Life Stages, Gender and Temporalities. Historical and Sociological Reflections
Authors: Charles Aline , Charton Laurence , Baslyk Valentina 
Published: January 2021

Research Framework: Long conducted in parallel,
studies on life stages and gender have converged more in recent years, but still
leave large areas uncovered. Some analyzes still treat sex as a simple variable that
does not require problematization. Others lose sight of the fact that growing up and
aging generate categories and trajectories that are the result of interactions of
sex and age. The link between gender and age thus still needs to be tightened.
Objectives: The introductory article of the
issue " Life Stages, Gender and Temporalities" proposes to explore the interactions
between age and gender relations by examining the gendered constructions of ages and
the life trajectories structured by gender.
Methodology: This article lists studies by
sociologists and historians exploring gender/age links.
Results: The articles presented help to show to
what extent gender and age relationships overlap and interact in the development of
social inequalities throughout the life of individuals. They also participate in
questioning the social hierarchy which is "mechanically" based on gender and certain
age-related markers.
Conclusions: The joint analysis of gender and
age relations is progressing, but slowly, and still remains in the blind spot of
intersectional perspectives. While current research now recognizes gender and age as
constantly interacting systems, it too seldom addresses the power relations and the
cumulative inequalities they generate.
Contribution: This introductory article opens
up new research perspectives, both with regard to the gendered processes favouring
the development of sexual physical characteristics and to the dominant social codes
that shape heteronormative experiences and temporalities.
dynasor—A Tool for Extracting Dynamical Structure Factors and Current Correlation Functions from Molecular Dynamics Simulations
Authors: Fransson Erik , Slabanja Mattias , Erhart Paul , Wahnström Göran 
Published: January 2021

AbstractPerturbative treatments of the lattice dynamics are widely successful for many crystalline materials; however, their applicability is limited for strongly anharmonic systems, metastable crystal structures and liquids. The full dynamics of these systems can, however, be accessed via molecular dynamics (MD) simulations using correlation functions, which includes dynamical structure factors providing a direct bridge to experiment. To simplify the analysis of correlation functions, here the dynasor package is presented as a flexible and efficient tool that enables the calculation of static and dynamical structure factors, current correlation functions as well as their partial counterparts from MD trajectories. The dynasor code can handle input from several major open source MD packages and thanks to its C/Python structure can be readily extended to support additional codes. The utility of dynasor is demonstrated via examples for both solid and liquid single and multi‐component systems. In particular, the possibility to extract the full temperature dependence of phonon frequencies and lifetimes is emphasized.
Spatial–temporal thermal‐fluid behaviors of microbubble emission boiling (MEB)
Authors: Horiuchi Kazuna , Kobayashi Hotaka , Miyashita Shu , Hori Takuma , Ueno Ichiro 
Published: January 2021

AbstractWe investigate non‐uniform behaviors in space of the microbubble emission boiling (MEB). Special attention is paid to radial temperature difference on the heated surface before/after the onset of the MEB. Correlation among the regimes of the MEBs, the radial temperature difference in the heated surface and the vapor bubble behaviors is indicated experimentally. We find that the surface temperature near the center becomes higher in the transition to the MEB, and then it becomes lower in the developed MEB. It is found that a linear correlation between the power input to the heaters and the resultant heat flux on the heated surface breaks in the transition of the MEB. The difference of the MEB regimes, S‐MEB and C‐MEB, is apparently distinguishable by monitoring the radial temperature difference of the heated surface.

AbstractIntron retention (IR) has been implicated in the pathogenesis of complex diseases such as cancers; its association with Alzheimer's disease (AD) remains unexplored. We performed genome‐wide analysis of IR through integrating genetic, transcriptomic, and proteomic data of AD subjects and mouse models from the Accelerating Medicines Partnership‐Alzheimer's Disease project. We identified 4535 and 4086 IR events in 2173 human and 1736 mouse genes, respectively. Quantitation of IR enabled the identification of differentially expressed genes that conventional exon‐level approaches did not reveal. There were significant correlations of intron expression within innate immune genes, like HMBOX1, with AD in humans. Peptides with a high probability of translation from intron‐retained mRNAs were identified using mass spectrometry. Further, we established AD‐specific intron expression Quantitative Trait Loci, and identified splicing‐related genes that may regulate IR. Our analysis provides a novel resource for the search for new AD biomarkers and pathological mechanisms.
Boosting the Electrocatalysis of MXenes by Plasmon‐Induced Thermalization and Hot‐Electron Injection

Published: January 2021

AbstractThe MXenes attract great interest in catalytic and energy applications but suffer from inferior redox activity. An efficient strategy is presented to boost the intrinsic electrochemical activity of MXenes for electrocatalysis in various chemical environments by utilizing their plasmonic response to electromagnetic waves. The resulting significant thermoplasmonic effect lowers the endothermic enthalpy and potential barrier to the hydrogen evolution reaction (HER) in the Vis/near‐IR region. Simultaneous hot‐electron injection in a prolonged sub‐femtosecond to picosecond timescale also remarkably facilitates interfacial charge transfer and decreases the activation energy of the reaction. Both effects boost the HER activity of various types of MXenes over fivefold with improved kinetics and Faradaic efficiency over a broad pH range.
Site Selective Chlorination of C(sp3)−H Bonds Suitable for Late‐Stage Functionalization
Authors: Fawcett Alexander , Keller M. Josephine , Herrera Zachary , Hartwig John F. 
Published: January 2021

AbstractC(sp3)−Cl bonds are present in numerous biologically active small molecules, and an ideal route for their preparation is by the chlorination of a C(sp3)−H bond. However, most current methods for the chlorination of C(sp3)−H bonds are insufficiently site selective and tolerant of functional groups to be applicable to the late‐stage functionalization of complex molecules. We report a method for the highly selective chlorination of tertiary and benzylic C(sp3)−H bonds to produce the corresponding chlorides, generally in high yields. The reaction occurs with a mixture of an azidoiodinane, which generates a selective H‐atom abstractor under mild conditions, and a readily‐accessible and inexpensive copper(II) chloride complex, which efficiently transfers a chlorine atom. The reaction's exceptional functional group tolerance is demonstrated by the chlorination of >30 diversely functionalized substrates and the late‐stage chlorination of a dozen derivatives of natural products and active pharmaceutical ingredients.
Surface Modification of Black Phosphorus with Group 13 Lewis Acids for Ambient Protection and Electronic Tuning
Authors: Tofan Daniel , Sakazaki Yukako , Walz Mitra Kendahl L. , Peng Ruoming , Lee Seokhyeong , Li Mo , Velian Alexandra 
Published: January 2021

AbstractHerein we introduce a facile, solution‐phase protocol to modify the Lewis basic surface of few‐layer black phosphorus (bP) and demonstrate its effectiveness at providing ambient stability and tuning of electronic properties. Commercially available group 13 Lewis acids that range in electrophilicity, steric bulk, and Pearson hard/soft‐ness are evaluated. The nature of the interaction between the Lewis acids and thebP lattice is investigated using a range of microscopic (optical, atomic force, scanning electron) and spectroscopic (energy dispersive, X‐ray photoelectron) methods. Al and Ga halides are most effective at preventing ambient degradation ofbP (>84 h for AlBr3), and the resulting field‐effect transistors show excellentIVcharacteristics, photocurrent, and current stability, and are significantly p‐doped. This protocol, chemically matched tobP and compatible with device fabrication, opens a path for deterministic and persistent tuning of the electronic properties inbP.
Superior overall water splitting performance in polypyrrole photoelectrode by couplingNrGOand modifying electropolymerization substrate
Authors: Rasouli Haleh , Hosseini Mir Ghasem , Yardani sefidi Pariya , Kinayyigit Solen 
Published: January 2021

AbstractWe prepare photoelectrodes with mixed metal oxides (TiO2‐RuO2), polypyrrole (PPy) and N‐doped reduced graphene oxide (NrGO) on titanium (Ti) substrate for overall water splitting and methylene blue degradation during two steps; including a sol–gel deposition of mixed metal oxide (MMO) and electrodeposition of PPy or PPy‐NrGO films. The as‐prepared photoelectrodes are characterized by physical and photoelectrochemical measurements. Ti/MMO/PPy‐NrGO photoelectrode exhibit a considerably photocurrent density of −6.97 mA cm−2(at 0 V vs. reversible hydrogen electrode [RHE]) and 12.89 mA cm−2(at 1.23 V vs. RHE) for hydrogen and oxygen generations, respectively. However, promotion in the H+/H2efficiency (40.25%) is about 28 orders of magnitude while in the case of H2O/O2(13.77%) is 10 times. The electrochemical impedance spectroscopy and Mott–Schottky measurements reveal that the simultaneous incorporation of MMO and NrGO nanosheets in PPy coating leads to the lowest charge transfer resistance at the photoelectrode/electrolyte interface and an improvement in charge carrier density.
