Authors: Forero-Cabrera Nathalia María , Sánchez-Sáenz Carolina Maria
Published: August 2020

The importance of the selection and classification processes in the industry of agricultural products and the increase in the production of fruits make necessary the development and implementation of new techniques to efficiently perform these tasks. Techniques such as NIR spectroscopy have proved to have potential to accomplish this purpose. The aim of this research was to evaluate the performance of near infrared spectroscopy as a classification tool for agraz (Vaccinium meridionale Swartz), according to its state of maturity. In order to obtainthe classification models, the PCA and SIMCA methods were used. Results were obtained close to 100% accuracy in the classification for maturity stages 4 and 5 and between 81 and 90% for maturity stage 3. The NIR spectroscopy appears as a suitable technique for the classification of fruits of agraz according to their state of maturity.

Protection against corrosion by molten salts through aluminum coatings deposited by arc thermal spray on ASTM A53 grade B steel
Authors: Pérez Muñoz Diego , Marulanda-Arévalo José Luddey , Tristancho-Reyes José Luis
Published: August 2020

ASTM A53 steel samples were coated with aluminium by EATS, they report continuity and adherence. Thermal treatment improved their performance against corrosion, because the aluminium inter-diffusions are produced from coating into substrate and iron from substrate into coating. Samples were subjected to molten salts corrosion (20 % Na2SO4 and 80 % V2O5) at range of (400–600)° C. Samples were characterized by SEM-EDS and the morphology of layers were studied, noting good protection of layer deposited and the degradation of coating happened at above fusion temperatures of salts, besides the corrosion rate increases with temperature and decreases with exposition time.

Authors: Navarro Donoso Patricio , Vargas Riquelme Cristian , Castillo Jonathan , Sepúlveda Rossana
Published: August 2020

The entrainment of the organic phase in the aqueous applied to typical solutions in a solvent extraction of copper process was studied. The organic phase used is composed of the commercial extractant LIX 984-N diluted in Shellsol 2046 AR. The aqueous phase contains 6 g/L of Cu2+, at pH 2  and 20 ºC. The variables studied were: mixing speed of 400 to 1000 rpm; mixing time of 3 to 30 minutes; initial pH of the electrolyte 2, 3, and 4; percentage of extractant in the organic phase 10 to 30% v/v; and copper concentration in the aqueous phase 1 to 6 g/L. It was determined that the entrainment of the organic phase in the aqueous is determined by the physical properties of the phases in equilibrium and by the system’s hydrodynamics, and it is a phenomenon that involves the advancing speed of the interphase (or dispersion band) and the displacement speed of the organic drops.

Interference test interpretation in naturally fractured reservoirs
Authors: Escobar Freddy Humberto , Torregrosa Marlés Carlos Andrés , Olaya Marín Guiber
Published: August 2020

The naturally fractured reservoir characterization is crucial because it can help to predict the flow pattern of fluids, and the storativity ratio of the fractures and to understand whether two or more wells have communication, among others. This paper presents a practical methodology for interpreting interference tests in naturally fractured reservoirs using characteristic points found on the pressure derivative curve. These kinds of tests describe a system that consists of a producing well and an observation well separated by a distance (r). Using characteristic points and features found on the pressure and pressure derivative log-log plot, Analytical expressions were developed from the characteristic points of the pressure and pressure derivative log-log plot to determine the interporosity flow parameter (λ) and the storativity ratio of the fractures (ω). Finally, examples are used to successfully verify the expressions developed so that the naturally-fractured parameters were reproduced with good accuracy.

Published: August 2020

The effect of partial replacement of wheat flour with turmeric flour (Curcuma longa) on the physicochemical and sensory properties of chorizo made with pork was evaluated. Three levels of turmeric flour substitution were proposed 0.8%, 1.4% and 2.1%, corresponding to a substitution of a 19.04%, 33.33% and 50,00%, respectively, along with a control chorizo without the addition of said flour. The pH, water holding capacity, color, texture and sensory evaluation were measured. The pH tended towards acidity in the treatment with the greatest inclusion of uremic flour. The sensory evaluation was carried out with to untrained panelists who determined the chorizo with the highest acceptability. For the sensory parameters, there were no significant differences, except for color. Therefore, turmeric flour can be used as a partial substitute for wheat flour in the production of common chorizo without affecting physicochemical and sensory properties.

Authors: Mangelli Tarcio S. , Zapelini Cleverson , Da Rocha Wesley Duarte , Schiavetti Alexandre
Published: August 2020

Monitoring surveys provide data needed to assess ecosystem conditions in places where bioinvasion occurs. The collection of data by volunteer researchers (citizen science) is an alternative for scientists and research agencies that lack information but do not have sufficient financial resources. The objective of this study was to evaluate marine monitoring using voluntary recreational scuba diving to identify invasive exotic marine species at eight diving sites distributed between the north of Ilha Grande and the municipality of Angra dos Reis in the Central Channel of Ilha Grande Bay, Rio de Janeiro state. During the three months of study, 207 questionnaires were evaluated. The results showed that the group of volunteer divers with more experience identified a greater number of invasive exotic species compared to the group of divers with less experience. No statistical difference was found in the number of species identified between the groups of volunteer divers with and without a species identification chart. As a recommendation for the use of citizen science, it is necessary to use divers with greater diving experience. Developing stricter protocols for the identification of invasive exotic marine species is essential for the collection of quality data. The improvement of monitoring programs based on citizen science can provide useful information for research on biodiversity in marine environments, significantly reducing financial costs and time in the field, in addition to contributing to the ecological knowledge, awareness and environmental education of participants
Major Factors Associated with Congenital Malformations in the Agadir Region of Morocco
Authors: EL MADIDI SAID
Published: August 2020

Introduction: Congenital malformations are a global health problem around the world. MCs is one of the main causes of death and disability of newborns worldwide, but the majority of its risk factors are still poorly understood.

Objective: The aim of this study is to determine the main causes that are related to the incidence of congenital malformations (CMs) in the region of Agadir in Morocco.

Material and Methods: A prospective cases-control study at regional level was conducted in the pediatrics and neonatology department of Hassan II hospital in Agadir from April 2016 to April 2018. Data on child and maternal variables were recorded for 3701 newborns. The types of congenital malformations  have been classified according to the codes of the International Classification of Diseases. Univariate analyzes were performed to identify the variables associated with the etiology of the malformations. Multiple logistic regression was used to characterize the associations between the MC and the determining explanatory variables taken into account simultaneously.

Results: The results of these studies showed that there is a significant association between the incidence of the Congenital anomalies and the level of the consanguinity of the child, the prematurity of childbirth, the family history of CMs, the body mass index of the mother and the presence of major trauma during pregnancy.

Conclusion: our results have made it possible to highlight the existence of an association between a certain number of risk factors and the occurrence of congenital malformations. Additional studies are needed to confirm and clarify the role of these risk factors.

Refutation of a claim made by Fejes Tóth on the accuracy of surface meshes
Authors: Vegter Gert , Wintraecken Mathijs
Published: August 2020

Fejes Tóth [3] studied approximations of smooth surfaces in three-space by piecewise flat triangular meshes with a given number of vertices on the surface that are optimal with respect to Hausdorff distance. He proves that this Hausdorff distance decreases inversely proportional with the number of vertices of the approximating mesh if the surface is convex. He also claims that this Hausdorff distance is inversely proportional to the square of the number of vertices for a specific non-convex surface, namely a one-sheeted hyperboloid of revolution bounded by two congruent circles. We refute this claim, and show that the asymptotic behavior of the Hausdorff distance is linear, that is the same as for convex surfaces.
Zeros of the Riemann zeta-function in the discrete universality of the Hurwitz zeta-function
Authors: Laurinčikas Antanas
Published: August 2020

Let 0 < γ1 < γ2 < ··· ⩽ ··· be the imaginary parts of non-trivial zeros of the Riemann zeta-function. In the paper, we consider the approximation of analytic functions by shifts of the Hurwitz zeta-function ζ(s + iγkh, α), h > 0, with parameter α such that the set {log(m + α): m ∈ } is linearly independent over the field of rational numbers. For this, a weak form of the Montgomery conjecture on the pair correlation of {γk} is applied.

Published: August 2020

The aim of the experiment is to establish a method for the determination of acrylamide in food by automatic accelerated solvent extraction-gas chromatography-mass spectrometry. D3-acrylamide was used as isotope internal standard, crushed samples were extracted and purified by automatic accelerated solvent, acrylamide was derivatized into 2,3-dibromopropanamide by potassium bromide and potassium bromate under acidic conditions, and then the derivative was extracted by ethyl acetate and detected by gas chromatography-mass spectrometry. The method had a good linear relationship in the concentration range of 10–2000 ng/mL, and the coefficient of determination (R2) was 0.9997. The detection limit of the method was 3 μg/kg. The quantification limit of the method was 10 μg/kg. The standard addition recovery of acrylamide was between 105 and 120%, and the relative standard deviation of the recovery of acrylamide was less than 3.0%. The experimental result showed that the method was simple, sensitive, efficient and accurate, and could be used for the determination of acrylamide in food.

Published: August 2020

Introduction

To evaluate the automated cartridge-based PCR approach ARIES SARS-CoV-2 Assay targeting the ORF-sequence and the N-gene of SARS-CoV-2.

Methods

In line with the suggestions by Rabenau and colleagues, the automated ARIES SARS-CoV-2 Assay was challenged with strongly positive samples, weakly positive samples and negative samples. Further, intra-assay and inter-assay precision as well as the limit-of-detection (lod) were defined with quantified target RNA and DNA. The Cepheid Xpert Xpress SARS-Cov-2 Assay was used as gold standard.

Results

Concordance between the ARIES assay and the Cepheid assay was 100% for strongly positive samples and for negative samples, respectively. For weakly positive samples as confirmed applying the Cepheid assay, a relevant minority of 4 out of 15 samples (26.7%) went undetected by the ARIES assay. Intra- and inter-assay precision were satisfactory, while the lod was in the 103 DNA copies/reaction-range, in the 103 virus copies/reaction-range, or in the 103–104 free RNA copies/reaction-range in our hands.

Conclusions

The automated ARIES assay shows comparable test characteristics as the Cepheid assay focusing on strongly positive and negative samples but a slightly reduced sensitivity with weakly positive samples. Decisions on diagnostic use should include considerations on the lod.
The prospective effect of purpose in life on gambling disorder and psychological flourishing among university students
Authors: Zhang Meng Xuan , Yang Hong Mian , Tong Kwok-Kit , Wu Anise M. S.
Published: August 2020

Background and aims

Gambling disorder (GD) is a mental disorder with a relatively higher prevalence in university students compared to adolescents and adults. Its reciprocity with mental being indicators, such as psychological flourishing, would be expected, but prior to this study had not yet been empirically examined. In addition, the predictive value of purpose in life (PIL) on university students' GD and psychological flourishing also remained unknown. This 1-year longitudinal study was the first to test the potential bidirectional relationships among PIL, self-reported GD symptoms, and psychological flourishing.

Methods

In this study, a total of 283 university students (39.6% females; age = 18–27 years, M = 20.47, SD = 1.15) completed an anonymous questionnaire at both baseline and a year later in a follow-up study.

Results

The results of our cross-lagged analysis did not show the hypothesized reciprocity between GD symptoms and psychological flourishing (P > 0.05). However, PIL significantly predicted fewer GD symptoms (β = −0.23, P < 0.001) and higher levels of psychological flourishing (β = 0.30, P < 0.001) in the follow-up study. Moreover, psychological flourishing predicted PIL a year later.

Conclusion

The findings demonstrate the potential efficacy of purpose/meaning oriented interventions in gambling prevention and in well-being promotion programs.

Published: August 2020

Background and aims: The UK allows a number of gambling products to be legally used by people under the age of 18. The aim of this study was to explore associations between recalled legal usage of five youth gambling products and adult disordered gambling. Methods: A retrospective cross-sectional study of 1,057 adult UK gamblers, aged 18–40. Recalled legal use of five youth gambling products (category D fruit machines, coin push machines, crane grab machines, the National Lottery, and National Lottery scratchcards) was correlated with adult disordered gambling symptoms as measured by the Problem Gambling Severity Index (PGSI). Results: Recalled rates of legal engagement with each product ranged from 50.9% for Category D fruit machines to 96.6% for coin push machines. For category D fruit machines, the National Lottery, and National Lottery scratchcards, merely having legally engaged with these products as a child was associated with adult disordered gambling. Furthermore, higher levels of recalled legal youth usage with each of the five products was also associated with adult disordered gambling. Discussion and conclusions: These results relate to recent government proposals to increase the National Lottery scratchcard legal age to 18, and add to a wider literature on youth gambling and subsequent gambling-related harm.
‘These stories have to be told’
Authors: Mausfeld Dianne Violeta
Published: August 2020

In the late 1980s and early 1990s, Los Angeles gave rise to Chicano rap, a subgenre of gangster rap that uniquely incorporated transcultural signifiers of music and language. Key characteristics included ‘oldie’ and Chicano rock samples, multilingual lyrics and the proclamation of Brown pride. The lyrics treated gang violence, police brutality and daily life in the varrio (’hood), thus articulating the artists’ alienation from white America. While strongly identifying with both LA and their Mexican heritage, artists like (Kid) Frost created a brand-new music style that inspired a whole generation of bilingual rappers. Considering Chicano rap as historical source provides a deeper understanding of the issues Mexican-American youth in the US have been facing up to the present day. On the basis of (Kid) Frost’s music this article will trace cultural and social topics as well as musical features that mirror the resurfacing of Chicano consciousness and identity during the 1990s
Historical Silences, Musical Noise
Authors: Martin Toby
Published: August 2020

Much Australian history has argued that Australian culture and academic writing were largely silent on the issue of Aboriginal history prior to 1968. Further, there has been a common argument—and assumption—that non-Indigenous country music did not deal with Indigenous Australians in this period at all. However, Australia’s most popular recording artist, the country singer-songwriter, Slim Dusty, did in fact record several songs that dealt with issues such as the history of frontier massacres and Aboriginal pastoral labour during the 1950s and 1960s. These songs provide fascinating examples of alternative history-making, and show that there was a conversation—albeit limited—about difficult settler-colonial issues occurring in postwar popular culture. Dusty’s songs also provide new ways of thinking about music and politics in the civil rights era, supplying rich examples of the ways in which popular music in general can engage with complex historical narratives, and how popular culture can disrupt conventional ways of telling history.
How hard is it to remember Bananarama? The perennial forgetting of girls in music
Authors: Robinson Lucy
Published: August 2020

Remembering and forgetting female pop musicians sits within the broader project of feminist and queer identity histories. The history of uncovering a past in order to inform the here and now raises questions about the relationship between lived experiences and the types of history that are produced. There is an assumption that each may inform the other. In the 1980s, within the academy, there was a growing understanding of the importance of remembering and re-remembering marginalized agents. This sat alongside an increasing visibility of the girl, both as a market and as a performer. Looking at the discourses, remembering and forgetting, seeing and silencing of the successful girl band Bananarama, I will map the active levels through which female performers have been marginalized, have resisted and persisted. I ask: what will it take for them to be remembered?

A force measuring microsystem bases on electrothermal V-shaped actuator
Authors: Phuc Pham Hong
Published: August 2020

This paper describes design and calculation of an electrothermal V-shaped actuator (EVA) and an amplification mechanism integrated into a force measuring microsystem (FMMS), aims to apply for characterization of a micro beam. Displacement and driving force are generated by thermal expansion of the V-shaped silicon beams while applying a voltage to the electrodes of the EVA. ANSYS simulation helps to find out the relations between thermal force and displacement corresponding to driving voltage and determine the temperature of V-shaped beam at various applying voltages. In our simulation, with applying voltage Um = 38 volt for six pairs of V-shaped beam, the maximal temperature of the beam reaches approximately to 1100°C and causes a melting phenomenon of the silicon beam. The additional amplification mechanism allows actuator's displacement to be 6 times larger than before the improvement, thus the bending deformation of the micro beam can be seen perfectly, i.e. the force loading on the beam can be computed more exactly via a measured displacement of the beam tip. In addition, this FMMS has smaller size and supplies a larger beam's deformation at the same voltage in comparison with previous design.

Published: August 2020

Bir ülkede sürdürülebilir kalkınma için temel maliye politikası aracı olan vergiler, önemli kamu geliri türüdür. Vergilerin gelir sağlama dışında ekonomik ve sosyal amaçları da bulunmaktadır. Bu amaçları gerçekleştirecek vergi sisteminin oluşturulmasında önemli parametrelerden biri vergi esnekliğidir. Vergi esnekliğinin bilinmesi vergi sisteminin otomatik stabilizatör olma özelliği, artan oranlılık ve hedeflenen vergi geliri tahmini için önem arz eder. Bir ülkede inelastik bir vergi sistemi, toplanacak vergiler konusunda belirsizlik yaratmaktadır. Bu çalışmanın amacı, Türkiye’de 2002-2019 döneminde özel tüketim vergisinde (ÖTV) vergi esnekliğinin teorik değere uygun olup olmadığını OECD ülkeleriyle karşılaştırmalı olarak incelemektir. Olumsuz dışsallıkları önleme, tersine artan oranlılığı azaltma gibi işlevleri gereği vergi sisteminin temel yapı taşları arasında yer alan ÖTV’nin, beklentileri yerine getirmesinin ölçümünde vergi gelir esnekliği önemli bir araçtır. Çalışmanın sonucunda ÖTV’de Türkiye’deki vergi gelir esnekliğinin OECD ülkelerinden düşük olduğu görülmüştür.

Published: August 2020

Introduction: in the modern world, the level of international terrorism is constantly growing, with an increasing tendency for terrorists to use an impressive arsenal of weapons of destruction, which creates a real threat to the world community, for all countries without exception. The use of various types of explosive devices in public places – streets, railway stations, and trains – is directed by terrorists to intimidate the population and create a serious threat to stability and security in society. Therefore, at the present stage, it is important to apply all previously developed methods and techniques, as well as to use new recommendations in order to improve the logistics of the law enforcement agencies. The involvement of specialists in conducting such an important investigative action as the inspection of the accident scene will contribute to an objective perception, a full study of the scene, the detection, recording and removal of various traces and other physical evidence in order to clarify the nature of the event. The purpose of the study: to determine the methods available to the investigator, providing the maximum possible information for further investigation of the crime. The objectives of the study: to describe the principles of modern tactics of conducting the accident scene observation; to clarify requirements and review the specifics of the inspection report of the explosion scene; to develop recommendations on the examination and recovery of the objects. Methods: the methodological framework is based on the methods of historicism, systematization, and comparative law. Results: the proposals were made to improve the interaction of the investigator with the forensic expert involved in the scene examination. Conclusions: as a result of the study, it is revealed that when the forensic examination of corpses or their fragments discovered at the accident scene when an explosive device was used, an approximate list of questions for the forensic expert is formed for the investigators. It is established that the use of the techniques available to the investigator provides the necessary information for further investigative actions.
The Development of Regulation of the Family and Marriage Institutions in Russia in the Context of the Decisions of the European Court of Human Rights
Authors: Mamay Evgeny , Ermakova Julia
Published: August 2020

Introduction: the institution of marriage is the pillar of every society and state and forms their material, spiritual, psychological and even ideological basis. The state is inextricably linked with the family and marriage. Changing each of the elements of this interaction leads to the radical changes in the entire system, so the state must regulate these social institutions in a certain way. Modern Russia strives to achieve a reasonable balance of human rights and freedoms, develop a democratic society and work closely with the international community while preserving the established moral foundations and traditional values related to the institution of the family and marriage. The purpose of the publication is to determine the current state and prospective vectors of development of the state policy in relation to the institution of marriage. The research methodology is based on the use of the logical, dialectical techniques and methods of scientific knowledge, the comparative legal and legal-technical analysis of the texts of laws and other documents. Results: the paper analyzes the scientific literature, the Russian and foreign legislation, the international legal acts and decisions of the European Court of Human Rights in order to determine the efficiency of the state policy in this area, establish the criteria for achieving a sufficient balance between the non-interference of the state in the gender issues and maintaining the institution of traditional marriage in Russia. The conducted research of the issue suggests that in general, the legislation of the Russian Federation concerning the family and marriage relations is quite stable, but in response to the challenges of modern times, it is undergoing a certain reform. Conclusions: the practice of implementing the European Convention on Human Rights requires that the Russian legislation be seriously reformed in terms of regulating the gender issues and marital and family relations. In recent years, the Russian Federation has repeatedly lost cases in the European Court of Human Rights (ECHR), without being able to defend the fairness of its position. According to the authors of the publication, the solution to this problem is possible by reviewing certain international obligations of Russia in the context of their interpretation of the ECHR, as well as forming a consolidated position in Russian society regarding the institution of traditional marriage and the gender relations. These changes should be reflected in both the domestic legislation and the legalized law enforcement practices. The authors consider the achieved level of tolerance of Russian law regarding the institutions of the family and marriage to be extremely sufficient for the preservation and sustainable development of Russian society.
The Implementation of the Educational Function of Witness Interrogation as an Element of Countering Crimes of Extremism
Authors: Slavgorodskaya Olga
Published: August 2020

Introduction: countering crimes of extremism is one of the most urgent tasks of our time. To solve this problem, a variety of tools and methods are actively used, including the capabilities currently developed by criminalistics. One of the promising directions in the development of improving measures to counter extremism is the formation of a morally oriented personality. In this regard, the purpose of the study was to consider the possibilities of educational influence on witnesses during interrogation in criminal cases of extremism. Methods: the methodological framework for this research was based on the methods of systematicity, analysis, historicism and comparative law. Results: the author’s well-grounded position was based on the consideration of the possibility of using educational influence on various categories of witnesses in the investigations of crimes of extremism. In the study of the possibilities of using educational effects, the relationship between the influences of the investigator on the witness was studied. On the basis of the conducted research, the differentiation of characteristic categories of witnesses subject to interrogation in this category of criminal cases under investigation was made. The author studied the peculiarities of forming professional competencies of investigators and the possibilities of using their key elements to make a positive impact on witnesses. Based on the analysis of the basics of interrogation tactics, the place of psychological contact was determined as an element that helps to strengthen the positive impact on the witness during the interrogation. Conclusions: as a result of the research, the existing relationship between the educational influences exerted by the investigator during the interrogation of witnesses in the investigation of crimes of extremism was revealed. It was established that educational influence could be used as one of the measures to counteract this type of crime.
Landscape and Geomorphological Features of Ravine Systems Developed in Sand Deposits of the Southern Part of the Volga Upland
Authors: Dedova Irina
Published: August 2020

The article deals with the morphological features of the profile and slopes of ravine systems developed in sand deposits of the southern part of the Volga Upland. The author notes that the southern part of the Volga Upland is a vast inter-river space bounded by the river valleys of the Don and the lower reaches of the Ilovlya river in the west and the Volga river and Volgograd reservoir in the east. This area has a potential for water and wind erosion. This is determined by the features of the geological structure (the development of Cenozoic Eocene-Oligocene marine deposits represented by alternating layers of clays, siltstones, sandstones and sands and Neogene-Quaternary sand-loam covers), as well as hilly type of terrain. The density of the erosion net here is 0.8–1.0 km/km2. The ravine and river valleys of the territory under consideration are typified by the age and morphological criteria into 4 types: middle and late Pliocene valleys of the Don drainage basin; Pleistocene valleys of widespread distribution; late Pleistocene valleys of the Don drainage basin; modern Holocene erosional forms. Broad floodplains with sandy loam alluvium, flattened valley slopes, and trough-shaped cross-sections are noted as common features of the structure of ravine and river valleys. The role of deflation and water erosion in the evolution of the slope microrelief of erosion forms is analyzed. The role of ravine systems in the formation of natural-territorial complexes of psammophytic steppes with a significant share of rare plant species, as well as the spread of bayrachny forest in the dry-steppe zone is noted. The predominant role of such natural-territorial complexes as psammophytic sagebrush-cereal sparse steppes on the sodsandy soils of the Don above-floodplain terraces; sparse dry sheep fescue and white artemisia steppe on the light mechanical composition of the soils of the Ergeninsk sands on the ravine slopes is noted. Among the intrazonal natural-territorial complexes, ravine and floodplain poplar-oak and old-growth aspen-poplar forests are distinguished.
Retail Signage During the COVID-19 Pandemic
Authors: McNeish Joanne E.
Published: August 2020

Early in 2020 the COVID-19 pandemic began to impact countries across the world. Within weeks, people’s normal social behavior had to be changed in order to stop the spread of the disease. In Canada, where this study takes place, governments and public health departments were the primary and trusted information sources. Photographs of retail signs were taken by the author in one neighborhood in a major Canadian city in March and April. Along with descriptive information, the author speculates on the meaning conveyed by the printer-paper signs, beyond their traditional role of supporting wayfinding. Paper’s relative fragility may have simultaneously reflected the uncertainty that people felt in the early days of the pandemic, while its familiar and timeless presence may have provided a sense of emotional security and direction. Marking a return to “business as usual”, stores replaced many, but not all of the informal signs with professionally produced and branded signs suggesting that the early “blind panic” had been replaced by a form of “steady state”. One could say that retailers demonstrated corporate social responsibility through their efforts in creating and posting the signs to create awareness of, educate, and reinforce the new and changing social distancing behaviors.
Effects of Time for Deliberation and Disfluency on Omission Neglect

The use of disfluency in marketing signage has more complex effects than what past research suggests. Time plays an important role in consumer information processing of signage presented disfluently. Three experimental studies suggest that the effects of disfluency on the awareness of missing information, purchase likelihood, and likelihood of future surprise depend on whether consumers have more or less time to process the information. When they have a limited amount of time, disfluency improves their awareness of missing information, leading to not only a lower likelihood of immediate purchase but also less surprise when important omissions are revealed later. Nevertheless, the effects are attenuated when consumers have a greater amount of time.
Simple or complex? Consumer response to display signs

Retail signage provides information from the marketer to facilitate product purchase. An increase in sign information creates greater sign complexity, which raises the question: for consumer product choices, what quantity of information is helpful versus overwhelming? We hypothesize that consumers would allocate more visual attention to complex signs and that sign complexity would be a predictor of likeliness to buy (LTB). Five experts rated 105 real garden center signs for complexity and five low, moderate, and highcomplexity signs were selected for the study. Signs were incorporated into Tobii X1 Light Eye Tracker software, where 85 non-student subjects rated sign attractiveness and LTB from a display containing that sign. Subjects allocated greater visual attention (higher fixation count and longer total fixation duration) to more complex signs, which were also rated as most attractive. Initial regression results showed sign attractiveness and fixation count were positive predictors of LTB, while complexity and total fixation duration were inversely related to LTB. Mediation analysis showed that fixation duration fully mediates fixation count impact on purchase intention. Results suggest that informationrich messaging in high complexity signs, while seen as attractive, may give consumers too much information and higher cognitive load, which makes decision-making more difficult.
A Sign of Trust? The value of source attribution in accolade claims
Authors: Isaac Mathew S.
Published: August 2020

Organizations that have received an accolade or honor often share this information with current or prospective customers, either in a digital (i.e., on their website, social media, etc.) or physical (i.e., on-premise signs, outdoor signs, etc.) format. When publicizing their achievement, marketers must make decisions related to source attribution—that is, how much detail to provide and how prominently (if at all) to mention the thirdparty entity that bestowed the accolade upon them. This is an important question, particularly with respect to physical signs where informational complexity is often detrimental and visual clarity is paramount. In this research, I examine whether source attribution in signage materially affects consumer evaluations and behavioral intentions. Across three studies, I find converging evidence that source attribution in accolade claims does in fact bolster evaluations and behavioral intentions, even in the context of physical signage when consumers are likely to be engaged in heuristic processing. Furthermore, I provide evidence that these more positive judgments arise because attribution increases perceived credibility of the organization receiving the accolade.
Introduction

Published: August 2020

Our newest issue of the Interdisciplinary Journal of Signage and Wayfinding focuses on communication effectiveness at the intersection of consumers’ perception and their experience. This special issue features work from marketing and communication scholars who explore the visual characteristics of signage as they influence evaluations, purchase intentions, detection of omission, and compliance. Given the timing of this issue, it is not surprising that the COVID-19 pandemic provided a highly relevant context in which to study consumers’ perception of visual information. As such, two of the articles presented discuss signage within the context of the global pandemic specifically. Other articles present important research on topics related to sign complexity and consumer perceptiveness.
