mWOM Business Strategies: Factors Affecting Recommendations

ABSTRACT The aim of this paper is to understand why shoppers who use smartphones to make their purchases recommend shopping through this channel. To do this, the influence of the main relational marketing variables on the Word of Mouth (WOM) generated by shoppers is analyzed. The model shows the effect of reputation, loyalty and relational quality (satisfaction, trust, and affective commitment) on the WOM published after buying different things using smartphones. The proposed model explains the background of the influence of mWOM on m-shopping using smartphones based on rela-tional variables (Satisfaction, Trust and Affective Commitment), a com-mon external variable of the online environment (online reputation) and loyalty as a habitual precedent of WOM. The main contributions of this study are the recommendations that consumers with experience of mobile shopping make about the use of this channel based on both relational and external variables with gender as a moderating variable.
New Insights into the Chemical Composition of Ayahuasca

Ayahuasca is a psychedelic beverage originally from the Amazon rainforest used in different shamanic settings for medicinal, spiritual, and cultural purposes. It is prepared by boiling in water an admixture of the Amazonian vine Banisteriopsis caapi, which is a source of β-carboline alkaloids, with plants containing N,N-dimethyltryptamine, usually Psychotria viridis. While previous studies have focused on the detection and quantification of the alkaloids present in the drink, less attention has been given to other nonalkaloid components or the composition of the solids suspended in the beverage, which may also affect its psychoactive properties. In this study, we used nuclear magnetic resonance (NMR) and liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) to study the composition of ayahuasca samples, to determine their alkaloid qualitative and quantitative profiles, as well as other major soluble and nonsoluble components. For the first time, fructose was detected as a major component of the samples, while harmine (a β-carboline previously described as an abundant alkaloid in ayahuasca) was found to be present in the solids suspended in the beverage. In addition, N,N-dimethyltryptamine (DMT), harmine, tetrahydroharmine, harmaline, and harmol were identified as the major alkaloids present in extracts of all samples. Finally, a novel, easy, and fast method using quantitative NMR was developed and validated to simultaneously quantify the content of these alkaloids found in each ayahuasca sample.
Synergy Effect and Symmetry-Induced Enhancement Effect of Surface Multi-Defects on Nanohardness by Quasi-Continuum Method

The quasicontinuum method has been applied to probe the thin film with surface multi-defects, which is commonly seen in nanoimprint technique and bulk micromachining. Three unilaterally distributed multi-defect models and six bilaterally distributed multi-defect models of Pt thin film have been carried out in nanoindentation. The results show that the nanohardness gradually decreases as the number of unilaterally distributed multi-defects increases, along with the increasingly low decline rate of the nanohardness. The synergy effect of the unilaterally distributed multi-defects has been highly evidenced by the critical load revision for dislocation emission of Pt thin film, and it is predicted into a universal form with the synergy coefficient among the existing multi-defects for FCC metals. Moreover, the nanohardness obviously increases when the bilaterally distributed multi-defects form into symmetrical couple, and it could be even greater than the one with defect-free surface, due to the symmetry-induced enhancement effect on nanohardness. The symmetry-induced enhancement coefficient has been brought out and has well explained the symmetry-induced enhancement effect of bilaterally distributed multi-defects on the nanohardness by a prediction formula. Furthermore, the characteristic length of symmetric relations has been brought out to calculate the symmetry-induced enhancement coefficient and it has been effectively predicted to equal to the sum of the adjacent distance between the surface defect and the indenter, the defect depth near the indenter, and the defect width for FCC metal.
Prediction of Indoor Environmental Quality Using a Regression Model for Educational Buildings in Hot Arid Climate: A Case Study in the Al-Najaf Technical Institute – Iraq

In hot climates, achieving a good indoor environmental quality (IEQ) in existing buildings is important especially with climate change challenges as future heat waves will increase in frequency, duration, and intensity. In educational buildings, there is much more focus on the IEQ parameters and the interactions among them that need to be in line with the continuously changing learning environment. This study assesses the IEQ parameters (represented by noise, temperature and humidity) at three selected campus areas (lecture rooms of an administrative department building (LR), main hall of a management department building (MH) and a central library building (CL)) at the Al-Najaf Technical Institute (NTI), Al-Najaf City, Iraq, for the period from May to December 2019. A statistical analysis using a multi-linear regression model was performed to determine the relationship between the selected IEQ parameters and explain the noise level behavior as a function of the temperature and relative humidity. The research indicated that the noise levels and temperature values exceeded the maximum standard limits in all buildings reflecting the displeasing sound and heating quality within the studied areas, while the readings for relative humidity within each building environment complied with standards. Moreover, for both LR and MH buildings (R2 ≥ 0.8, significance F ≤ 0.01), the noise values were satisfactorily modeled by temperature and relative humidity highlighting the interactions between temperature, humidity and noise under consistent conditions. However, the results for the CL building (R2 = 0.6, significance F = 0.1) showed no relationship between the IEQ parameters, highlighting the fact that this building is exposed to unsteady conditions (an irregular number of people using this building during the daytime) resulting in a high variation of data measurements. The current results demonstrate that detailed modeling can be helpful to predict IEQ parameters depending on other known parameters in buildings. The results of the predictive model aligned with the directly measured data. Therefore, its performance is equally effective, but with a significant reduction in cost and time consumed.
Angular frequency variations at microgrids and its impact on measuring instruments performance

The aim of this study is to discuss the challenges that will be faced by the designers of measuring instruments in future, in the wake of the proliferation of microgrids. In this context, the fluctuations in the angular frequency of the fundamental component of the voltage and the resulting changes in the duration of the measurement windows are considered. The main objective of this study is to consider this variation in the angular frequency from the point of view of the IEC Standard 61000-4-7, using real signals. Numerous results from the experiments conducted in 11 electric power networks, chiefly marine microgrids, are presented, and discussed. A comparative analysis of the behaviour of two measuring instruments is also provided. Both the instruments are based on different signal processing principles. One of them utilises the signal processing method recommended in the IEC 61000-4-7 standard, whereas, the other is based on the application of the chirp z-transform principle.
Reverse Versus Radical Discourse: A Qualified Critique of Butler and Foucault, with an Alternative Interactive Theorisation

ABSTRACT This article explores the concept of reverse discourse, as suggested by Foucault and Butler. It is argued that Butler's concept of subject formation is overly determinist, as is Foucault's of discourse. Following Scott's critique, it is argued that there is a strong and a weak conceptualisation of dominant ideology. Discourses are in competition for authority, where dominant ideology is the discourse of more powerful decision-makers, while subaltern ideologies persist. This leads to a more interactive theory of structural constraint and the conditions of possibility for radical action. Social actors can change power relations by reproducing dominant discourses while reversing implied power-authority relations – reverse discourse. Alternatively, more radically, they can resist dominant ideology by attempting to build consensus around subaltern ideology, which is incommensurable with dominant ideology. Reverse discourse has the advantage over radical critique in that it reproduces the natural-order-of-things. However, it has the disadvantage of reproducing reifying norms.
New bat records in south-eastern Bosnia and Herzegovina with additional confirmation of Myotis alcathoe and Myotis brandtii

The Balkans represent one of the regions with the highest bat diversity in Europe. Thus far, 31 bat species have been recorded in Bosnia and Herzegovina (BiH). The bat fauna of this Balkan country is one of the least studied in Europe. In order to reduce this knowledge gap, bat research was carried out during a ten-day inventory in the vicinity of Čajniče in south-eastern BiH (Republic of Srpska). Mist net surveys resulted in the capture of 15 bat species: Rhinolophus ferrumequinum, R. hipposideros, Myotis brandtii, M. mystacinus sensu lato, M. alcathoe, M. emarginatus, M. nattereri, M. bechsteinii, M. blythii, Nyctalus leisleri, Eptesicus serotinus, Vespertilio murinus, Pipistrellus pipistrellus, P. pygmaeus, and Plecotus auritus. Acoustic surveys resulted in recording one additional species: Barbastella barbastellus. Roost surveys yielded in the finding of three maternity colonies of R. hipposideros. The genetic analysis resulted in the first molecularly confirmed M. brandtii and M. alcathoe records for BiH. Capture of several post-lactating females, sexually active males and multiple juveniles is proof for reproducing populations of these species in the country. During this brief study, we found more than half of all known bat species in BiH in an area of circa 75 km2 .
Application of An Equivalent Homogeneous Line Model to A Transient Analysis on A Distribution System

The paper proposes a simplified model to deal with a distribution system which involves a number of nodes and branches due to earth wire grounding at every some ten meters. The grounding, which is a typical boundary condition, is combined with the shunt admittance of a distributed-parameter line, and thus a distribution line with a number of the earth wire groundings is represented by an equivalent homogeneous line. The input impedance evaluated using the proposed model agrees with the accurate input impedance. Transients on a distribution system are calculated using the proposed model and the results show a satisfactory accuracy compared with the accurate solutions. By this approach, a computation time step of a transient is greatly increased and therefore a CPU time and a memory required are greatly reduced. The proposed model is expected to be very efficient to carry a transient analysis on a distribution system.
Inter-Rater Reliability of Reflective-Writing Assessment in an Undergraduate Professionalism Course in Medical Education

Reflective writing is increasingly being used in the teaching of professionalism. Because assessment enhances the learning process, effective evaluation of students’ reflective writing is needed. The aim of this study was to examine the inter-rater agreement between two different reflective writing assessment rubrics, which categorised reflective writings into four level of reflection, in an undergraduate medical professionalism course. The reflective writing assignments from 63 medical students enrolled in the 2017 medical professionalism course in the Faculty of Medicine Universitas Indonesia were randomly selected and independently assessed by two raters in September 2019. Intraclass correlation (ICC) analysis (two-way mixed effect, single measure) was carried out to determine the inter-rater agreement of the reflective writing assessment. The less detailed instrument showed a low ICC score of 0.43, which was classified into poor inter-rater agreement, whereas the more detailed rubric showed poor to moderate reliability, with ICC scores of 0.50, 0.50, and 0.36 for the score of each criterion, the total score of each assessed criterion, and the overall score of reflection, respectively. Utilising a more detailed (analytic) rubric to assess students’ reflective writing produced a relatively higher score of interrater reliability, although the reliability achieved using this rubric was still categorised as moderate.
Effect of Replacing Sorghum Stubble with Tillandsia recurvata (L.) on Liveweight Change, Blood Metabolites, and Hematic Biometry of Goats

Simple Summary Tillandsia recurvata is an epiphyte that contains adequate protein and energy levels regardless of the season and can be used as forage for small ruminants. We evaluated the effects of substituting sorghum stubble for T. recurvata in adult goats for 89 d, including an adaptation period of 14 d, at three different levels: 0% (control), 30%, and 60%. At the last phase of the trial, control goats gained more weight than goats consuming T. recurvata. Overall, the metabolic status was similar among treatments, whereas some variables tested of the complete blood count differed among treatments. Interestingly, the inclusion of T. recurvata in goats’ diets at 30% gained or at 60% decreased 1% live weight; without signs of health disturbance. Using up to 60% T. recurvata in the diet did not negatively affect animal health; however, under the conditions of this study, supplemental protein would be required when T. recurvata completely replaced sorghum stubble. The use of T. recurvata as a supplement for goats would improve the nutrition of grazing goats in the dry season compared to the current diet obtained from arid rangelands and would alleviate host trees invaded by this aggressive epiphyte. Abstract Tillandsia recurvata is an epiphyte that grows on the canopy of many trees in tropical and subtropical areas of America. The objective of this study was to evaluate the effect of partial or complete substitution of sorghum stubble with T. recurvata on liveweight change, metabolic profile, and complete blood count of goats fed increasing levels (0, 30, and 60%, dry matter basis) of T. recurvata. Thirty non-pregnant three-year-old, non-lactating, healthy mixed-breed goats, ten animals per treatment (T0, T30, and T60), were adapted to diets and facilities for 14 days (d-14). Blood samples were collected at d-15, 28, and 56. At the last phase of the trial (from days 67 on), control goats tended to gain more (p = 0.09) weight than their counterparts consuming T. recurvata. Plasma protein, glucose, triglycerides, calcium, and phosphorus concentrations did not differ among dietary treatments (p > 0.05). Dietary treatment influenced red blood cells (higher for T60; p < 0.01), white blood cells (higher for T30; p < 0.05), mean corpuscular volume (higher for T0; p < 0.001), and mean corpuscular hemoglobin concentration (higher for T0; p < 0.01), although not the rest of the blood variables (p > 0.05). The hematocrit percentage tended to be higher (p = 0.06) in T30 than T0 and T60. It was concluded that replacing sorghum stubble with T. recurvata did not modify the metabolic status and maintained live weight of goats. Nevertheless, the use of T. recurvata as feed for goats would improve the nutrition of these animals in the dry season compared to the current diet obtained from an arid rangeland, reducing production costs, and would alleviate the damage caused by this aggressive epiphyte to host trees.
The Psychological Distress of Cancer Patients following the COVID-19 Pandemic First Lockdown: Results from a Large French Survey

Simple Summary Cancer patients commonly experience anxiety which could increase with the COVID-19 pandemic situation. The aim of this study was to measure post-traumatic stress disorder (PTSD) and anxiety in cancer patients in France following the first COVID-19-related lockdown and associated factors. We found that the factors associated with PTSD and anxiety were different in nature. Factors associated with PTSD were not related to cancer but to the COVID-19 crisis, while factors associated with anxiety were mainly cancer related. More specifically, the fear of coming to hospital because of the risk of contracting COVID-19 was the strongest predictor of PTSD, and a better lockdown experience was protective against PTSD. Fear of cancer recurrence appear to be the main predictor of anxiety. Our study highlights the need to better integrate psychosocial support in pandemic response measures. Healthcare providers should not prioritize COVID-19 over cancer as the latter remains a central concern for cancer patients. Abstract Cancer patients commonly experience psychological distress that may increase with the current COVID-19 pandemic. This prospective study aimed to measure post-traumatic stress disorder (PTSD) and anxiety in cancer patients following France’s first COVID-19-related lockdown, together with associated factors. Cancer patients receiving outpatient treatment or post-treatment follow-up completed a questionnaire which measured, among other things, PTSD (IES-R), anxiety (State-Trait Anxiety Inventory), and fear of cancer recurrence (FCR). Of the 1097 patients included in the study, 14.7% and 30.5% suffered from PTSD and anxiety, respectively. Patients afraid to come to hospital due to the risk of COVID-19 transmission (OR = 3.49, p < 0.001), those with a negative lockdown experience (OR = 0.98, p < 0.001), women (OR = 1.97; p = 0.009), and patients living alone (OR = 1.63, p = 0.045) were all more likely to have PTSD. Older patients (OR = 1.65, p = 0.020), women (OR = 1.62, p = 0.018), those with a higher FCR score (OR = 5.02, p < 0.001), patients unsatisfied with their cancer management (OR = 2.36, p < 0.001), and those afraid to come to hospital due to COVID-19 (OR = 2.43, p < 0.001) all had a higher risk of anxiety. These results provide a greater understanding of the psychological consequences of the COVID-19 pandemic in cancer patients and highlight the need to better integrate psychosocial support in pandemic response measures in order to guide health systems.
Physiological and biochemical responses of osmo-primed parsley seeds subjected to saline stress

Water and salt stress conditions affect germination and seedling emergence. It is known that physiological priming can not only trigger different mechanisms to increase the speed and uniformity of germination, but also influence the antioxidant defence system of the seeds, especially in adverse conditions. In this context, the objective of this work was to evaluate the physiological seed quality and the activity of antioxidant enzymes in seeds of Petroselinum crispum induced to tolerate saline stress through osmo-priming. Seeds were placed in polyethylene glycol solutions with three osmotic potentials (-0.5, -1.0 or -1.5 MPa) for 2, 4 or 6 days. Subsequently, they were placed on substrates moistened with sodium chloride solution (NaCl), in concentrations that generated osmotic potentials of -0.2, -0.4, -0.6, -0.8 or -1.0 MPa, to germinate. The germination percentage, germination speed index, seedling length, fresh weight, dry weight and activity of the antioxidant enzymes superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) were evaluated. Germination and germination speed index decreased linearly with the increase in NaCl concentrations, indicating the species sensitivity. As for length, fresh weight and dry weight of seedlings, this effect was more expressive from the potential of -0.4 MPa. The vigour and activity of SOD, POD, and CAT enzymes were reduced in unprimed seeds, emphasising the effectiveness of the technique. The induction of tolerance to saline stress can be related to the activity of the antioxidant system observed in seeds.
Unraveling the population structure of the sugarcane borer, Diatraea saccharalis, in Argentina

Diatraea saccharalis (Fabricius) (Lepidoptera: Crambidae) is one of the major lepidopteran pests throughout the Western Hemisphere. In Argentina, it causes significant losses mainly in sugarcane (Saccharum officinarum L.) and corn (maize, Zea mays L.) (both Poaceae). Previous studies determined the existence of reproductive incompatibilities between populations from Buenos Aires and Tucumán from different host plants; however, the genetic basis of this incompatibility is still unknown. As the effectiveness of pest control programs mainly depends on strategies that minimize the risk of favoring insecticide‐resistant genotypes, estimating the level of mating between genotypes is important to monitor and manage resistance. The aim of this study was to characterize the genetic structure of D. saccharalis populations collected from various hosts and regions in Argentina, comparing with those from Brazil, through cytochrome c oxidase subunit I (COI) analysis and next‐generation sequencing (NGS). The COI analysis showed a haplotypic diversity of 0.8 and a nucleotide diversity of 0.0058. Analysis of molecular variance revealed greater variation within populations than among them. The 17 haplotypes detected were linked in a single parsimony network that did not reveal clusters based on geography or host plants. In total, 4549 single nucleotide polymorphism markers (SNPs) were obtained through NGS. Out of the 2349 outlier loci, 84 showed similarities with previously characterized proteins. The coefficient of inbreeding showed evidence of random matings as well as some degree of selection. The fixation index values showed high genetic variation between Argentinean and Brazilian populations; however, there was no clear trend based on distance or hosts. Similarly, the discriminant analysis of principal components revealed three separate groups: one Brazilian and two Argentinean. Results generated important clarification of the population genetic structure of D. saccharalis in South America, which provides information about routes of dispersal and the development of suitable management strategies.
Virality, only the tip of the iceberg: ways of spread and interaction around COVID-19 misinformation in Twitter

Misinformation has long been a weapon that helps the political, social, and economic interests of different sectors. This became more evident with the transmission of false information in the COVID-19 pandemic, compromising citizens’ health by anti-vaccine recommendations, the denial of the coronavirus and false remedies. Online social networks are the breeding ground for falsehoods and conspiracy theories. Users can share viral misinformation or publish it on their own. This encourages a double analysis of this issue: the need to capture the deluge of false information as opposed to the real one and the study of users’ patterns to interact with that infodemic. As a response to this, our work combines the use of artificial intelligence and journalism through fact-checked false claims to provide an in-depth study of the number of retweets, likes, replies, quotes and repeated texts in posts stating or contradicting misinformation in Twitter. The large sample of tweets was collected and automatically analysed through Natural Language Processing (NLP) techniques, not to give all the attention only to the posts with a big impact but to all the messages contributing to the expansion of false information or its rejection regardless of their virality. This analysis revealed that the diffusion of tweets surrounding coronavirus-related misinformation is not only a domain of viral tweets, but also from posts without interactions, which represent most of the sample, and that there are no big differences between misinformation and its contradiction in general, except for the use of replies.
