Sponsored Posts from Instagram Influencers and Purchase Intentions: The Mediating Role of the Perceived Value of Sponsored Posts

examine the impact of the Instagram users’ attitudes towards influencers on their attitudes towards sponsored posts on Instagram. This study further explores the mediating effects of the perceived value of sponsored posts on the relationship between attitudes towards influencers and attitudes towards sponsored posts, which in turn affects purchase intention.A structured online questionnaire was developed using Qualtrics and distributed through Amazon Mechanical Turk (M-Turk). A regression-based mediation analysis using the PROCESS macro and simple linear regression analysis were used to test hypotheses. The results of the study revealed that Instagram users’ attitudes towards influencers had a significant and positive impact on their attitudes towards sponsored posts on Instagram, which in turn affected purchase intention. The mediation analysis showed that the perceived value of a sponsored post—entertainment, credibility, or irritation—had significant mediating impact on the relationship between the user’s attitude towards the influencer and the users’ attitude towards the sponsored post. However, the perceived value of the informativeness of a sponsored post was not a significant mediator. The findings of this study provide real-world applications and guidelines for influencer marketing when advertising through sponsored posts on Instagram. The results of this study suggest that marketers and advertisers need to develop enjoyable, trustworthy, and non-irritating sponsored posts on Instagram that can generate a positive attitude towards the influencer and the sponsored posts, further positively affecting customers’ purchase intentions.

Data-driven materials research enabled by natural language processing and information extraction

Given the emergence of data science and machine learning throughout all aspects of society, but particularly in the scientific domain, there is increased importance placed on obtaining data. Data in materials science are particularly heterogeneous, based on the significant range in materials classes that are explored and the variety of materials properties that are of interest. This leads to data that range many orders of magnitude, and these data may manifest as numerical text or image-based information, which requires quantitative interpretation. The ability to automatically consume and codify the scientific literature across domains—enabled by techniques adapted from the field of natural language processing—therefore has immense potential to unlock and generate the rich datasets necessary for data science and machine learning. This review focuses on the progress and practices of natural language processing and text mining of materials science literature and highlights opportunities for extracting additional information beyond text contained in figures and tables in articles. We discuss and provide examples for several reasons for the pursuit of natural language processing for materials, including data compilation, hypothesis development, and understanding the trends within and across fields. Current and emerging natural language processing methods along with their applications to materials science are detailed. We, then, discuss natural language processing and data challenges within the materials science domain where future directions may prove valuable.
Study of serum cortisol levels in complicated and uncomplicated Plasmodium vivax malaria patients

Background: Malaria results in pathological changes in various body organs, as the parasite invade and multiply in circulating red blood cells. Despite of advances in diagnostic and treatment modalities, worldwide incidences of malaria are significant. Current study was conducted to investigate serum cortisol level changes as a promising biomarker for risk prediction in malaria and to study adrenal insufficiency in malaria patients.Methods: Current investigation was a prospective observational study, conducted on complicated and uncomplicated Plasmodium vivax malaria patients. Serum cortisol levels in patients were investigated through immunoassay using direct chemiluminescent technology and were statistically correlated with Plasmodium vivax malaria infection.Results: Results of present investigation revealed that on day 1 there was significant difference in mean serum cortisol levels between the Plasmodium vivax malaria patients and control group and cortisol levels were significantly higher in complicated Plasmodium vivax malaria patients compared to uncomplicated cases on day 1 and 7. Cortisol levels were observed to be normal on day 1 and 7 in uncomplicated malaria cases and in patients with bleeding manifestations, renal failure and jaundice. In 10 out of 15 cases of cerebral malaria, significant increase in serum cortisol levels were observed on day 1, while on day 7 levels were normal in all 15 cases.Conclusions: Rise in serum cortisol level had a positive correlation with temperature and thus can be useful to predict the severity of disease in Plasmodium vivax malaria patients. No cortisol insufficiency was observed in during active and convalescent stages of illness.

Organic vapors emitted from solvents used in chemical / food / pharmaceutical processes, or from hydrocarbon fuel storage stations at oil terminals, can be efficiently captured by adsorption onto activated carbon beds. The overall objective of the research program is the experimental and simulation studies of the adsorption and regeneration steps in the case of VOC removal which accounts into industrial emissions by Temperature Swing Adsorption (TSA) and Vacuum Temperature Swing Adsorption (VTSA) processes. This is achieved by the following steps : to establish the isotherm equilibrium data for 5 VOCs and 8 activated carbons at 293, 313, 333, and 353 K (totally 120 isotherm experiments) and then use them in the simulation model; to develop a simulation model for adsorption and regeneration process; to design and optimize the experimental setup of Thermal Swing Adsorption (TSA) which has been established in Ecole des Mines de Nantes; to design and optimize the experimental setup of Vacuum Temperature Swing Adsorption processes (VTSA) which has been established in GRL ARKEMA unit ; simulation validation of experimental results of TSA and VTSA process. Once after the completion of all the objectives, the goal is to develop and launch a complete simulation package for adsorption and regeneration steps of VOCs with the co-operation from PROSIM Corporation.
I know who you are, but do others know? Why correct scientific names are so important for the biological sciences

Researchers are continuing to identify polychaetes using inappropriate references and failing to appreciate that many if not most species have restricted distributions. Using Marphysa sanguinea (Montagu, 1813) as a case example, we discuss the loss of valuable data by misidentifying a species. We suggest ways in which this problem can be addressed by both taxonomists, ecologists and other researchers. Furthermore, this situation is not unique to polychaetes but applies to many other groups of marine invertebrates.
Broadband Microstrip Antenna for 5G Wireless Systems Operating at 28 GHz

Communication systems have been driven towards the fifth generation (5G) due to the demands of compact, high speed, and large bandwidth systems. These types of radio communication systems require new and more efficient antenna designs. This article presents a new design solution of a broadband microstrip antenna intended for use in 5G systems. The proposed antenna has a central operating frequency of 28 GHz and can be used in the LMDS (local multipoint distribution service) frequency band. The dimensions of the antenna and its parameters have been calculated, simulated, and optimized using the FEKO software. The antenna has a compact structure with dimensions (6.2 × 8.4 × 1.57) mm. Rogers RT Duroid 5880 material was used as a substrate for the antenna construction, which has a dielectric coefficient of 2.2 and a thickness of 1.57 mm. The antenna described in the article is characterized by a low reflection coefficient of −22.51 dB, a high energy gain value of 3.6 dBi, a wide operating band of 5.57 GHz (19.89%), and high energy efficiency.
Measurement report: dual-carbon isotopic characterization of carbonaceous aerosol reveals different primary and secondary sources in Beijing and Xi'an during severe haze events

Abstract. To mitigate haze pollution in China, a better understanding of the sources of carbonaceous aerosols is required due to the complexity in multiple emissions and atmospheric processes. Here we combined the analysis of radiocarbon and the stable isotope 13C to investigate the sources and formation of carbonaceous aerosols collected in two Chinese megacities (Beijing and Xi'an) during severe haze events of a “red alarm” level from December 2016 to January 2017. The haze periods with daily PM2.5 concentrations as high as ∼ 400 µg m−3 were compared to subsequent clean periods (i.e., PM2.5 less than median concentrations during the winter 2016/2017) with PM2.5 concentrations below 100 µg m−3 in Xi'an and below 20 µg m−3 in Beijing. In Xi'an, liquid fossil fuel combustion was the dominant source of elemental carbon (EC; 44 %–57 %), followed by biomass burning (25 %–29 %) and coal combustion (17 %–29 %). In Beijing, coal combustion contributed 45 %–61 % of EC, and biomass burning (17 %–24 %) and liquid fossil fuel combustion (22 %–33 %) contributed less. Non-fossil sources contributed 51 %–56 % of organic carbon (OC) in Xi'an, and fossil sources contributed 63 %–69 % of OC in Beijing. Secondary OC (SOC) was largely contributed by non-fossil sources in Xi'an (56±6 %) and by fossil sources in Beijing (75±10 %), especially during haze periods. The fossil vs. non-fossil contributions to OC and EC did not change drastically during haze events in both Xi'an and Beijing. However, compared to clean periods, the contribution of coal combustion to EC during haze periods increased in Xi'an and decreased in Beijing. During clean periods, primary OC from biomass burning and fossil sources constituted ∼ 70 % of OC in Xi'an and ∼ 53 % of OC in Beijing. From clean to haze periods, the contribution of SOC to total OC increased in Xi'an but decreased in Beijing, suggesting that the contribution of secondary organic aerosol formation to increased OC during haze periods was more efficient in Xi'an than in Beijing. In Beijing, the high SOC fraction in total OC during clean periods was mainly due to an elevated contribution from non-fossil SOC. In Xi'an, a slight day–night difference was observed during the clean period with enhanced fossil contributions to OC and EC during the day. This day–night difference was negligible during severe haze periods, likely due to the enhanced accumulation of pollutants under stagnant weather conditions.
Sensitive fluorescence detection of saliva pepsin by a supramolecular tandem assay enables the diagnosis of gastroesophageal reflux disease

ABSTRACT Gastroesophageal reflux disease (GERD) is a prevalent gastrointestinal disorder with substantial morbidity. However, the reliable, non-invasive, and specific diagnosis of GERD remains a challenge due to the lack of specific symptoms and imaging features. Herein, we report a supramolecular tandem assay through using a reporter pair of sulfonatocalix[4]arene and lucigenin for the sensitive and real-time detection of saliva pepsin, an ideal biomarker for GERD. Moreover, we achieve the detection of pepsin in commercial artificial saliva, demonstrating the potential of this supramolecular approach for point-of-care testing of GERD. GRAPHICAL ABSTRACT
Salinity Tolerance of Four Hardy Ferns from the Genus Dryopteris Adans. Grown under Different Light Conditions

Hardy ferns form a group of attractive garden perennials with an unknown response to abiotic stresses. The aim of this study was to evaluate the tolerance of three species of ferns of Dryopteris genus (D. affinis, D. atrata and D. filix-mas) and one cultivar (D. filix-mas cv. “Linearis-Polydactylon”) to salinity and light stress. The plants were grown in full sun and shade and watered with 50 and 100 mM dm−3 NaCl solution. All taxa treated with 100 mM NaCl responded with reduced height, leaf greenness index and fresh weight of the above-ground part. In D. affinis and D. atrata salinity caused leaf damage manifested by necrotic spots, which was not observed in the other two taxa. The effect of NaCl depended on light treatments and individual taxon. D. affinis and D. atrata were more tolerant to salinity when growing under shade. Contrary to that, D. filix-mas cv. “Linearis-Polydactylon” seemed to show significantly greater tolerance to this stress under full sun. Salt-treated D. filix-mas cv. “Linearis-Polydactylon” plants accumulated enhanced amounts of K+ in the leaves, which might be associated with the taxon’s tolerance to salinity. Among the investigated genotypes, D. filix-mas cv. “Linearis-Polydactylon” seemed the most and D. affinis and D. atrata the least tolerant to salinity and light stress.
Feeding Models to Optimize Dairy Feed Rations in View of Feed Availability, Feed Prices and Milk Production Scenarios

In the global dairy production sector, feed ingredient price and availability are highly volatile; they may shape the composition of the feed ration and, in consequence, impact feed cost and enteric methane (CH4) emissions. The objective of this study is to explore the impact of changes in feed ingredients’ prices and feed ingredients’ availability on dairy ration composition, feed cost and predicted methane yield under different levels of milk production. To meet the research aim, a series of multi-period linear programming models were developed. The models were then used to simulate 14 feed rations formulations, each covering 162 months and three dairy production levels of 10, 25 and 35 kg milk/d, representing a total of 6804 feed rations altogether. Across milk production levels, the inclusion of alfalfa hay into the feed rations declined from 55% to 38% when daily milk production increased from 10 to 35 kg, reflecting the cows’ increased energy requirements. At a daily milk production level of 35 kg, CH4 production (per kg milk) was 21% and 53% lower than in average and low milk producing cows, respectively, whereas at 10 kg of milk production the potential to reduce CH4 production varied between 0.6% and 5.5% (average = 3.9%). At all production levels, a reduction in CH4 output was associated with an increase in feed costs. Overall, and considering feeding scenarios in low milk producing cows, feed cost per kg milk was 30% and 37% higher compared to that of average and high milk production, respectively. The feed ration modeling approach allows us to account for the interaction between feed ingredients over time, taking into consideration volatile global feed prices. Overall, the model provides a decision-making tool to improve the use of feed resources in the dairy sector.
Theory Development in Thematic Analysis: Procedure and Practice

ARTICLE DETAILS ABSTRACT History: Accepted 30 Nov 2020 Available Online 31 Dec 2020 Thematic analysis has widely been used in qualitative data analysis for theory development. This paper illustrates step-by-step procedure of qualitative data analysis through thematic analysis. Thematic analysis was performed on ten in-depth interviews which were transcribed for analysis. Coding in qualitative research is a systematic process through which the collected data were condensed into smaller analyzable units, called as codes, which were further categorized and developed into themes. Coding process eventually helped researchers to build a general theoretical concept about the qualitative evidence. Major themes that emerged in this analysis include (i) the management issues and (ii) employees’ apprehensions. Findings were interpreted and their implications were discussed in detail in the section of conclusion.
Study of In-situ And Laboratory Hydraulic Conductivity of Contaminated Soil with Oily Wastewater

This study aims to investigate the effect of contaminated soil samples with oily wastewater which were taken from Kawergosk refinery (20 km west of Erbil city). Laboratory constant head permeability tests on contaminated soil samples with oily wastewater have been conducted. Also, One-Dimensional (1-D) and Three-Dimensional (3-D) in-situ permeability tests were performed. A noticeable decrease in the values of hydraulic conductivity coefficient (k) have been observed for Contaminated Soil Samples comparing with uncontaminated samples. Results of hydraulic conductivity coefficient obtained from one dimensional consolidation tests were increased with increasing of applied stresses. The results of field permeability tests revealed that the surrounding lands of Kawergosk refinery lies within the range of semi-permeable area for urban development while the majority part of the area lies within the range of moderate area for agricultural and conservation purposes.
Elucidating and exploiting the chemistry of Keggin heteropolyacids in the methanol-to-DME conversion: enabling the bulk reaction thanks to operando Raman

Operando Raman spectroscopy is used here to enlighten crucial and yet unconsidered aspects of the catalytic behavior of Keggin heteropolyacids (HPAs) in the gas phase dehydration of methanol to dimethylether (DME). On one hand, HPAs are since a long time claimed as being able to absorb methanol into their bulk, but on the other hand this feature is not yet really exploited when it comes to develop/use HPA-based catalysts for the methanol-to-DME process. Actually, the conditions in which the bulk is simultaneously accessible and catalytically active are not yet clearly reported. Clarifying this is precisely the aim of our work, for which we have used H3PW12O40 and H4SiW12O40. We precisely operando-follow the νs(WOt) band reflecting whether methanol penetrates or not in the HPAs' bulk. We show that, when the HPAs are used without having been beforehand completely dehydrated, methanol penetrates into their bulk. However, the conversion remains low (<5% at 150 °C) due to remaining crystallisation water reducing the availability of the active protons within the bulk, so limiting the activation of methanol. A complete dehydration pre-treatment is thus required if one wants to fully benefit of the bulk reactivity. However, we show that this benefit is obtained only if the pre-treatment is done adequately. The most intuitive pre-treatment, namely the HPAs' dehydration at about 300 °C and then cooling down to the reaction temperature 150 °C at which methanol is fed, is shown to be inefficient. This is due to the inaccessibility of the fully dehydrated bulk to methanol, so limiting the catalytic reaction to only the surface of the HPAs. At the opposite, a pre-treatment sequence consisting of dehydrating at 300 °C, then cooling down to 25 °C, exposing to methanol at this temperature, and then only heating to the reaction temperature, is shown to succeed combining penetration of methanol into the bulk and availability of the active protons. With such sequence, an unprecedented conversion of 40% is obtained thanks to a full exploitation of the HPAs' bulk. These results show that the HPAs' bulk can contribute significantly to convert methanol, provided that the catalysts are properly pre-treated.
