The Contribution of Digital Marketing to Business Performance: The Case of Companies in the Northern Region of Morocco

Digital marketing is revolutionizing the organizational structures and offers companies, especially Moroccan companies, a multitude of opportunities to evolve the classic business model to innovate in products and services while building a direct and personalized relationship with customers. Indeed, digital marketing highlights important features for companies seeking efficiency and performance, and it considers an attractive alternative to traditional approaches as a response to the challenges of globalization. The ultimate objective of our research is to confirm the direct relationship between digital marketing and the business performance of companies in the northern region of Morocco. The result of the study was noted by many authors. On this matter, we have conducted a quantitative survey carried out among 120 companies in the northern region of Morocco using the PLS path modeling, a method particularly suited for academic development and predictive applications. According to our empirical study, we found that digital marketing has a positive impact on the performance of companies in the northern region of Morocco.
Simultaneous‐source deblending using adaptive coherence‐constrained dictionary learning and sparse approximation

The dictionary learning and sparse approximation method using the K‐singular value decomposition algorithm rely on the knowledge of the sparsity or noise variance as a constraint when it is used for data denoising. However, the determination of the sparsity or noise variance of seismic data can be tricky and sometimes unknown, especially in seismic field data. Thus, where the cardinality or the noise variance is not known, the intrinsic character of the relative coherence between the removed noise from noisy data and its learned dictionary is instead used as a constraint for the sparse approximation of simultaneous‐source seismic data. The dictionary learning is obtained using a modified orthogonal matching pursuit algorithm which uses coherence as a constraint and is referred to as coherence dictionary learning. The coherence dictionary learning is then adapted to handle the simultaneous‐source seismic data deblending. A blending structure with random time dithering of sequential source shooting is used to guarantee adequate randomness of the noise. Two‐dimensional overlap patches of the noisy data were extracted from the common receiver gather domain to train the dictionary and to determine the sparse representation of the signal. The method is tested on both synthetic and field data, and it shows adequate data recovery. Comparing the result of this method to the matching pursuit algorithm constrained by the signal sparsity and the noise variance reveals that our approach performs better at noise attenuation and yields a reasonable data recovery especially for strong seismic signal.
Ancient genomes from the initial Jomon period: new insights into the genetic history of the Japanese archipelago

Starting 16000 years ago, the Neolithic lifestyle known as the Jomon culture spread across the Japanese archipelago. Although extensively studied by archaeology and physical anthropology, little is known about the genetic characteristics of the Jomon people. Here, we report the entire mitogenome and partial nuclear genome of skeletal remains from the initial Jomon period that were excavated from the Higashimyo shell midden site at Saga City, Kyushu Island, Japan. This is the first genome analysis of the initial Jomon people of Kyushu Island. These results provide important data for understanding the temporal transition and regional differences of the Jomon people. The mitochondrial DNA and Y-chromosome haplogroups were similar to those found in the previously reported later Jomon people. Moreover, comparison of three nuclear genomes from the initial to final Jomon periods indicated genet ic continuity throughout the Jomon period within the Japanese archipelago with no significant evidence of admixture. This indicates that the genetic differentiation found among the Jomon people was promot ed by the progression of regionalization throughout the Jomon period. Further accumulation of high-quality Jomon genome data spanning a wide range of regions and ages will clarify both intimate regional and temporal differences of the Jomon people and details of their admixture history with rice farmers, as suggested by Jomon mitochondrial genome data. The results obtained from this study provide important information for further analysis.
The Aquila Digital Community The Aquila Digital Community Restorative Justice and the School-To-Prison Pipeline: A Review Restorative Justice and the School-To-Prison Pipeline: A Review of Existing Literature of Existing Literature

: Black students experience out-of-school suspensions at a higher rate than other students. The higher rate at which these students are suspended is believed to contribute to a school-to-prison pipeline. This review article is designed to enhance the understanding of this problem by focusing on the factors that play a part in the school-to-prison pipeline. A purposeful sample of recently published literature by some of the leading scholars in this area was selected for analysis. Some studies indicate that school personnel may be biased in the ways they respond to Black students. The lack of teacher preparation and support has been documented to be one of the contributing factors as well. Researchers have also referred to the similarities between urban schools and other schools with high concentrations of Black students, arguing that these schools implement more punitive approaches to discipline. This review article enhances the understanding of a possible way to deal with this problem by including content about how implementing effective restorative discipline programs may alleviate the school-to-prison pipeline.
THE ROLE OF TEMPERATURE AND AIR QUALITY IN OUTDOOR RECREATION BEHAVIOR: A SOCIAL-ECOLOGICAL SYSTEMS APPROACH

ABSTRACT Ambient air pollution and rising global temperatures pose dual threats to the health and well-being of urban residents, in part, through dissuading them from engaging in healthy, outdoor physical activity. We leveraged a social-ecological systems (SES) framework to explain weather-dependent, outdoor recreation in the wildland-urban interface of Salt Lake City, Utah. Using 24-hour trail camera monitoring for 32 days, we measured trail use and ambient temperature. Additionally, we accessed particulate matter (PM2.5) and ozone (O3) data to assess the impact of air quality on outdoor recreation behaviors. Curvilinear regression analysis illustrated temperature predicted 45.9 percent of the variance in outdoor recreation use, while bivariate analyses show particulate matter and ozone also served as substantial predictors. These results further parameterize components of this complex SES, and help demonstrate the utility of trail cameras in collecting localized thermal measurements, along with temporal and activity-specific distributions in use.
In-hospital prognosis of first-ever noncardiogenic ischemic stroke in patients with and without indication for prestroke antiplatelet therapy: Chinese Stroke Center Alliance

Background It is unknown about the influence of prestroke antiplatelet use on early outcomes in patients with and without the indication. We aimed to evaluate the in-hospital prognosis of first-ever noncardiogenic ischemic stroke patients with and without indications of antiplatelet use for primary prevention. Methods This was a retrospective, observational study based on a prospective hospital-based registry (Chinese Stroke Center Alliance). Using the data with 436,660 first-ever noncardiogenic acute ischemic strokes recorded from Aug 1, 2015, to July 31, 2019, from 1,453 hospitals in China, we examined the associations between the indication for prestroke antiplatelet use and in-hospital clinical outcomes. Results Among 436,660 first-ever noncardiogenic ischemic stroke patients, 42,409 patients (9.7%) had a documented previous vascular indication and 394,251 (90.3%) did not. Compared to those without, patients with the indication were associated with increased prevalence of in-hospital morbid conditions, including stroke severity (OR 2.71; 95% CI: 2.62–2.81; P<0.0001), length of stay >14 days (OR 1.16; 95% CI: 1.13–1.19; P<0.0001), mortality (OR 2.20; 95% CI: 1.96–2.46, P<0.0001), and recurrence of ischemic stroke and transient ischemic attack (TIA) (OR 1.5; 95% CI: 1.43–1.59, P<0.0001). Among patients without indication, prestroke antiplatelet use was associated with lower mortality (OR 0.73, 95% CI: 0.56–0.96; P=0.0221); while among patients with indication, those receiving prestroke antiplatelet had lower odds ratios in stroke severity (P<0.0001) and disability (P=0.0003) than those who not. Conclusions Patients with indications of prestroke antiplatelet use were more likely to have unfavorable outcomes than those without. Prestroke antiplatelet might be associated with lower mortality, less disability, and less stroke severity in certain population groups. Future studies to improve risk prediction rules are needed to guide effective primary prevention for ischemic stroke.
Acceptance of Google Meet during the Spread of Coronavirus by Arab University Students

The COVID-19 pandemic not only affected our health and medical systems but also has created large disruption of education systems at school and universities levels. According to the United Nation’s report, COVID-19 has influenced more than 1.6 billion learners from all over the world (190 countries or more). To tackle this problem, universities and colleges have implemented various technologically based platforms to replace the physical classrooms during the spread of Coronavirus. The effectiveness of these technologies and their educational impact on the educational sector has been the concern of researchers during the spread of the pandemic. Consequently, the current study is an attempt to explore the effect of Google Meet acceptance among Arab students during the pandemic in Oman, UAE, and Jordan. The perceived fear factor is integrated into a hybrid model that combines crucial factors in TAM (Technology acceptance Model) and VAM (Value-based Adoption Model). The integration embraces perceived fear factor with other important factors in TAM perceived ease of use (PEOU) and perceived usefulness (PU) on the one hand and technically influential factor of VAM, which are perceived technicality (PTE) and perceived enjoyment (PE) on the other hand. The data, collected from 475 participants (49% males and 51% females students), were analyzed using the partial least squares-structural equation modelling (PLS-SEM). The results have shown that TAM hypotheses of usefulness and easy to use have been supported. Similarly, the results have supported the hypotheses related to VAM factors of being technically useful and enjoying, which helps in reducing the atmosphere of fear that is created due to the spread of Coronavirus.
Degradation fitting of irradiated solar cells using variable threshold energy for atomic displacement

Characteristic degradation curves for proton and electron induced degradation of triple junction (3J) and isotype Ga0.5In0. 5P/GaAs/Ge solar cells were obtained. The displacement damage dose methodology in combination with a varying effective threshold energy for atomic displacement Td,eff was used to analyze 3G28 and 3G30 3J cell data. The nonionizing energy loss (NIEL) was calculated analytically, and Td,eff was explicitly introduced as a fit parameter. Using the GaAs NIEL in fitting the 3J degradation data, a Td,eff of 21 eV was determined, whereas a Td,eff of 36 eV was found using the Ga0.5In0. 5P NIEL. In GaAs and Ga0.5In0. 5P single junction cells, the effective threshold energies for atomic displacement of 22 and 34 eV were determined. Copyright © 2017 John Wiley & Sons, Ltd.
Relationship between Phase Composition and Mechanical Properties of Peat Soils Stabilized Using Oil Shale Ash and Pozzolanic Additive

Construction of road embankments in peatlands commonly involves replacement of the peat with a fill-up soil of an adequate load-bearing capacity. This usually requires a lowering of the water level, turning a peatland from a carbon sink to a source of greenhouse gases. Thus, alternatives are sought that are less costly in both economic and ecological terms. Mass-stabilization technology can provide a cheap substitute for Portland cement. Calcareous ashes (waste materials), supplemented with pozzolanic and alkali additives to facilitate and accelerate the setting and hardening processes, are attractive alternatives to soil excavation or replacement techniques. Silica fume and waterglass were used as pozzolanic agents and KOH as a soil-alkalizing agent. X-ray fluorescence (XRF), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) analyses and stress–strain tests were performed for the hardened samples. Crystallization of alkali feldspars was observed in all test samples. Comparable hardening of peat soil was achieved for both ashes. It was shown that the ashes of Estonian kukersite (oil shale) from both pulverized firing and a circulating fluidized bed incineration process (produced in energy sector as quantitatively major solid waste in Estonia) can be used as binding agents for peat stabilization, even without the addition of Portland cement. Hardened peat soil samples behaved as a ductile material, and the cellulose fibers naturally present in peat gave the peat–ash composite plasticity, acting mechanically in the same way as the steel or glass fiber in ordinary reinforced concrete. The effect of peat fiber reinforcement was higher in cases of higher load and displacement of the composite, making the material usable in ecological constructions.
Regime Switching in High-Tech ETFs: Idiosyncratic Volatility and Return

The volatility of asset returns can be classified into market and firm-specific volatility, otherwise known as idiosyncratic volatility. Idiosyncratic volatility is increasing over time with some literature attributing this to the IT revolution. An understanding of the relationship between idiosyncratic risk and return is indeed relevant for idiosyncratic risk pricing and asset allocation, in a context of emerging technologies. The case of high-tech exchange traded funds (ETFs) is especially interesting, since ETFs introduce new noise to the market due to arbitrage activities and high frequency trading. This article examines the relevance of idiosyncratic risk in explaining the return of nine high-tech ETFs. The Markov regime-switching (MRS) methodology for heteroscedastic regimes has been applied. We found that high-tech ETF returns are negatively related to idiosyncratic risk during the high volatility regime and positively related to idiosyncratic risk during the low volatility regime. These results suggest that idiosyncratic volatility matters in high-tech ETF pricing, and that the effects are driven by volatility regimes, leading to changes across them.
Industry 4.0 enabling technologies in manufacturing: implementation priorities and difficulties in an emerging country

ABSTRACT Industry 4.0 is one of the most heterogeneous waves of global industrialisation and the impact of new technologies in the industry is not clear. The present research aims to explore the perception of professionals from the Brazilian manufacturing sector regarding the main enabling technologies of Industry 4.0, their priority and difficulty level of implementation. A survey was carried out and collected data were analysed using a Fuzzy-TOPSIS approach. The results were summarised into a final ranking and it was possible to understand the perception of professionals regarding Brazilian manufacturing. For them, companies for aforementioned sector need to prioritise investments in shop-floor digitalisation (common fact in developing countries) and focus on understanding cybersecurity requirements (which hinders the implementation process). Understanding of Industry 4.0 phenomena in emerging countries is essential to grasp its particularities at a global level, helping researchers, decision-makers and policymakers to leverage Industry 4.0 in the context of a globalised economy.
Modest therapeutic effects of low-frequency transcutaneous electric nerve stimulation on insomnia among older adults: A 4-week multi-center, randomized controlled study

A 4-week, multi-center, randomized controlled study was conducted to evaluate the therapeutic efficacy and safety of low-frequency transcutaneous electric nerve stimulation (LF-TENS) for insomnia disorder. A total of 160 individuals aged 40 to 80 years with insomnia disorder were included and randomized to the experimental group receiving active device (n = 81) or control group receiving sham device (n = 79). Both groups used the device for four weeks, more than five days a week. The participants also completed pre- and post-intervention assessment with questionnaires, sleep diaries, wrist actigraphy, and blood tests. We found a significant improvement of subjective sleep quality, depressive/anxiety symptoms, and blood cortisol level in both experimental and control groups. Notably, among patients aged over 60 years, the experimental group showed better improvement after intervention in the change of PSQI score (2.60 ± 0.46 vs. 1.22 ± 0.46, p = 0.039; Cohen’s d = 0.99 vs 0.45) and blood cortisol level (-1.97 ± 0.53 µg/dl vs. -0.16 ± 0.53 µg/dl, p = 0.007; Cohen’s d = 0.56 vs 0.05). We found that LF-TENS was effective in improving subjective sleep quality in older adults aged over 60 years. The hypothalamic-pituitary-adrenal axis might be related to the therapeutic mechanism.
How to Produce and Measure Throughput Legitimacy? Lessons from a Systematic Literature Review

After two decades of research on throughput legitimacy, making sense of the stock of accumulated knowledge remains a challenge. How can relevant publications on throughput legitimacy be collected and analysed? How can the level of throughput legitimacy be measured? Which policy activities contribute to the production of throughput legitimacy? To answer these questions, we designed and implemented an original systematic literature review. We find that the measurement of the level of throughput legitimacy introduces a number of problems that call for the systematic and rigorous use of a more complete set of precise, specific indicators to advance the theory of throughput legitimacy. A number of participatory decision-making activities contribute to the production of throughput legitimacy. Engaging in these activities is not without risk, as variations in throughput legitimacy affect input and output legitimacy. To prevent vicious circles, lessons can be drawn from the literature on collaborative governance and decision-makers’ strategies to support effective collaboration between stakeholders.
Plagiomnium decursivum (Mniaceae), a new moss species from Japan and China

Abstract. Much attention has been focused on the moss family Mniaceae over the past 50 years, yet new discoveries continue to be made. Plagiomnium decursivum joins P. floridanum as the second new species of Plagiomnium Section Plagiomnium described in the past ten years. Careful morphological and anatomical studies, coupled with evidence from isozymes and gene sequencing, reveal that a species from Japan referred to in an earlier paper (Wyatt & Odrzykoski 1998) as “P. acutum” is actually new to science. In addition, the taxon referred to in that paper as “P. acutum-J” is in fact P. acutum, and the taxon referred to as “P. cuspidatum-F” is now named P. floridanum (Wyatt & Odrzykoski 2012). The new species, P. decursivum, is compared to its closest relative, P. acutum, and to the other four species of Section Plagiomnium. It differs in having smaller leaves with long, broad decurrencies, longer leaf cells with corner thickenings, and shorter teeth composed of a single cell. Based on isozyme data, it is concluded that allopolyploid P. cuspidatum has P. decursivum as one haploid progenitor and that P. floridanum is most likely the other. Moreover, sequencing of two regions of chloroplast DNA (rps4 and rpL16) suggests that P. floridanum may have been the maternal parent in crosses that launched the allopolyploid. The relative isolation of P. drummondii and P. japonicum within the section is apparent from both morphology and genetics.
Update on Pathologic and Radiologic Diagnosis of Combined Hepatocellular-Cholangiocarcinoma

Combined hepatocellular-cholangiocarcinoma (cHCC-CCA) is a malignant primary liver carcinoma characterized by the unequivocal presence of both hepatocytic and cholangiocytic differentiation within the same tumor. Recent research has highlighted that cHCC-CCAs are more heterogeneous than previously expected. In the updated consensus terminology and WHO 2019 classification, “classical type” and “subtypes with stem-cell features” of the WHO 2010 classification are no longer recommended. Instead, it is recommended that the presence and percentages of various histopathologic components and stem-cell features be mentioned in the pathologic report. The new terminology and classification enable the exchange of clearer and more objective information about cHCC-CCAs, facilitating multi-center and multi-national research. However, there are limitations to the diagnosis of cHCC-CCA by imaging and biopsy. cHCC-CCAs showing typical imaging findings of HCC could be misdiagnosed as HCC and subjected to inappropriate treatment, if other clinical findings are not sufficiently considered. cHCC-CCAs showing at least one of the CCA-like imaging features or unusual clinical features should be subjected to biopsy. There may be a sampling error for the biopsy diagnosis of cHCC-CCA. An optimized diagnostic algorithm integrating clinical, radiological, and histopathologic information of biopsy is required to resolve these diagnostic pitfalls.
Systematic Incorporation of Gold Nanoparticles onto Mesoporous Titanium Oxide Particles for Green Catalysts

This report describes the systematic incorporation of gold nanoparticles (AuNPs) onto mesoporous TiO2 (MPT) particles without strong attractive forces to efficiently serve as reactive and recyclable catalysts in the homocoupling of arylboronic acid in green reaction conditions. Unlike using nonporous TiO2 particles and conventional SiO2 particles as supporting materials, the employment of MPT particles significantly improves the loading efficiency of AuNPs. The incorporated AuNPs are less than 10 nm in diameter, regardless of the amount of applied gold ions, and their surfaces, free from any modifiers, act as highly reactive catalytic sites to notably improve the yields in the homocoupling reaction. The overall physical properties of the AuNPs integrated onto the MPT particles are thoroughly examined as functions of the gold content, and their catalytic functions, including the rate of reaction, activation energy, and recyclability, are also evaluated. While the rate of reaction slightly increases with the improved loading efficiency of AuNPs, the apparent activation energies do not clearly show any correlation with the size or distribution of the AuNPs under our reaction conditions. Understanding the formation of these types of composite particles and their catalytic functions could lead to the development of highly practical, quasi-homogeneous catalysts in environmentally friendly reaction conditions.
