Big Data has been created from virtually everything around us at all times. Every digital media interaction generates data, from computer browsing and online retail to iTunes shopping and Facebook likes. This data is captured from multiple sources, with terrifying speed, volume and variety. But in order to extract substantial value from them, one must possess the optimal processing power, the appropriate analysis tools and, of course, the corresponding skills. The range of data collected by businesses today is almost unreal. According to IBM, more than 2.5 times four million data bytes generated per year, while the amount of data generated increases at such an astonishing rate that 90 % of it has been generated in just the last two years. Big Data have recently attracted substantial interest from both academics and practitioners. Big Data Analytics (BDA) is increasingly becoming a trending practice that many organizations are adopting with the purpose of constructing valuable information from BD. The analytics process, including the deployment and use of BDA tools, is seen by organizations as a tool to improve operational efficiency though it has strategic potential, drive new revenue streams and gain competitive advantages over business rivals. However, there are different types of analytic applications to consider. This paper presents a view of the BD challenges and methods to help to understand the significance of using the Big Data Technologies. This article based on a bibliographic review, on texts published in scientific journals, on relevant research dealing with the big data that have exploded in recent years, as they are increasingly linked to technology
Oxidation or cation re-arrangement? Distinct behavior of riebeckite at high temperature

Published: December 2021

Abstract
In this work we address the stability of riebeckite at high temperatures and compare the different behaviors observed under various oxidation conditions. For this purpose, we annealed powders of a sample from Mt. Malosa (Malawi), which is compositionally close to the end-member; the run products obtained after annealing in air vs. in vacuum were studied by Mössbauer spectroscopy and powder X-ray diffraction. The results show that riebeckite follows two distinct paths depending on the external environment. Under oxidizing conditions, it is stable in the hydrous form up to relatively low temperatures (400–450 °C), then it undergoes a rapid (within ~50 °C) dehydrogenation, forming oxo-riebeckite, which is stable up to ~900 °C. The final breakdown products of the oxo-amphibole include aegirine + cristobalite + hematite. Based on the relative intensity of the (310) Bragg reflection, the activation energy (Ea) for the riebeckite to oxo-riebeckite transition is 166 ± 6 kJ/mol.
Under vacuum conditions, no Fe oxidation is observed, and riebeckite is stable up to much higher temperatures (750–800 °C); however, in the 550 &lt; T &lt; 700 °C range, it undergoes a significant re-arrangement of the C cations (those hosted in the strip of octahedra). Indeed, the amphibole stable in the 700–800 °C range has the same chemical formula as riebeckite but has a disordered and nonstandard cation distribution at the octahedra, i.e., M(1)(Fe3+Fe2+)M(2)(Fe3+Fe2+)M(3)Fe2+; we call this phase “CR3+ disordered riebeckite”. For T ≥ 800 °C, it decomposes to aegirine + fayalite + cristobalite + H2O.
External oxygen is required for the release of water into the surrounding system, being a prerequisite for the Fe-amphiboles to be a carrier of H2O in the lower crust and upper mantle. One important implication of our results is that characterization of the overall oxidation state of iron does not necessarily provide the redox conditions of the environment of formation because a crystal-chemical re-arrangement under reducing conditions allows riebeckite to maintain its Fe3+/Fe2+ composition up to higher temperatures.

Abstract
The Fe3+/FeT ratios (Fe3+/[Fe2++Fe3+]) in minerals can be used to understand their crystallization and post-crystallization conditions. However, as natural minerals are often zoned and contain inclusions, bulk techniques, e.g., wet chemistry, may not provide accurate Fe3+/FeT values for a single phase of interest. We determined Fe3+/FeT ratios of amphiboles in different crystallographic orientations by single-crystal synchrotron Mössbauer spectroscopy (SMS) in energy and time domain modes from four volcanic localities (Long Valley Caldera, Mount St. Helens, Lassen Volcanic Center, U.S.A., and Mt. Pinatubo, Philippines). The high spatial resolution (as low as 12 × 12 μm spot size) and standard-free nature of SMS allow the detection of intra-grain compositional heterogeneities in Fe3+/FeT with relatively low uncertainties.
We combine SMS with major element compositions, water contents, and hydrogen isotope compositions to document the Fe3+/FeT ratios as a function of mineral composition and post-crystallization dehydrogenation. Spectra were fitted with up to five distinct sites: ferrous iron on M(1), M(2), M(3), and ferric iron on M(2) and M(3), consistent with X-ray diffraction studies on single crystals of amphibole. The Fe3+/FeT ratios range from 0.14 ± 0.03 (Long Valley Caldera), 0.51 to 0.63 ± 0.02 (representing intra-grain heterogeneities, Mount St. Helens) to 0.86 ± 0.03 (Lassen Volcanic Center). The latter grain experienced post-crystallization dehydrogenation, shown by its low water content (0.6 ± 0.05 wt%) and its elevated hydrogen isotope composition (δD = +25 ± 3‰ relative to SMOW). The Fe3+/FeT ratios of 0.62 ± 0.01 and 0.20 ± 0.01 of two Mt. Pinatubo grains correlate with high-Al2O3 cores and low-Al2O3 rims and smaller phenocrysts in the sample, respectively. This study shows that SMS is capable of distinguishing two different domains with dissimilar Fe3+/FeT values formed under different crystallization conditions, demonstrating that SMS in combination with major element, water, and hydrogen isotope compositions allows the interpretation of amphibole Fe3+/FeT ratios in the context of crystallization and post-crystallization processes.
The Ideal Dimension of Law
Authors: Alexy Robert 
Published: December 2021

The main theme of the article is ideal dimension of law. Author argue for a dual nature thesis – which contends that law necessarily comprises both a real or factual dimension and an ideal or critical dimension – and demonstrates how the ideal dimension (which refers primarily to moral correctness) implies the truth of non-positivism. The key provisions of the conception represented in article are substantiated in a polemic with other well-known representative of non-positivism – John Finnis.
Particular attention is paid to determine relation between the real and ideal dimensions of law, which involves answering five questions. First, is there an outermost border of law? Second, is legal argumentation based exclusively on authoritative reasons or does it also include non-authoritative reasons? Third, what is the relation between human rights and legal systems? Forth, is democracy to be understood exclusively as a decision procedure or also as a form of discourse? Fifth, do legal system comprise only rules expressing a real “ought” or also principles expressing an “ideal ought”? These five questions are answered by the following five theses: the first with the Radbruch formula; he second with the special case thesis; the third with the thesis that constitutional rights are to be understood as attempts to positivize human rights; the fourth with the deliberative model of democracy; and the fifth with principles theory. All five theses turn on the same point: the claim to correctness.
A Pilot Study on the Degree of Tooth Staining Caused by Pollen Water and Chlorhexidine: In Vitro Study
Authors: Almulhim Khalid S. , Alhareky Muhanad S. , AlDakhil Ahmed Mohammed , Alsultan Odai , Barouch Kasumi K. 
Published: December 2021

Background:
Chlorhexidine oral rinse has been used as an adjuvant in the treatment of periodontal disease. However, there are drawbacks of using chlorhexidine i.e. tooth staining and other side effects, including allergy reaction. In light of the proven therapeutic properties of pollen water as well as its relatively cheap cost in the market, pollen water has a potential to be an effective alternative to chlorhexidine oral rinse. The aim of this study is to compare the degree of tooth staining influenced by water-based pollen mouthwash to the standard Chlorhexidine mouthwash using spectrophotometer.

Materials and Methods:
24 specimens from extracted intact human teeth were soaked into the three different solutions, Chlorhexidine, Pollen water (date palm pollen water suspension), and normal water. Color measurements were carried out by a spectrophotometer devise and recorded at 5 different time intervals. Color change (∆E), Chroma (C*) and Hue (H*) were analyzed and compared among the three solutions.

Results:
Overall mean ∆E was similar in all groups, significant difference between all time points was found only in pollen water. The change in C* was higher in pollen water as compared to other solutions. There was a subtle increase in H* in the Chlorhexidine samples after week 3. The H* values in pollen water were stable, but a sudden decrease was observed in week 6. The difference in H* among the three solutions was significant after 3 weeks.

Conclusion:
Within the limitation of our study, it can be concluded that Pollen water stained teeth to a lesser extent than did chlorhexidine. It might be beneficial to use Pollen water as mouthwash however, further investigation is needed regarding the efficacy of plaque control.
The Influence of the Material Properties on the Ultimate Behaviour of Aluminium H-shaped Beams
Authors: Montuori Rosario , Nastri Elide , Piluso Vincenzo , Pisapia Alessandro 
Published: December 2021

Background:
In this paper, the influence of the Ramberg-Osgood exponent on the ultimate behaviour of the H-shaped (or I-shaped) aluminium beams subjected to non-uniform bending moment is investigated.

Methods:
In particular, the results of a wide parametric analysis recently carried out by the authors are herein exploited to point out the influence of the material properties. The flange slenderness, the flange-to-web slenderness ratio, and the non-dimensional shear length, accounting for the moment gradient, are the main non-dimensional parameters governing the ultimate resistance and the rotation capacity of H-shaped aluminium beams.

Results:
The influence of these parameters was investigated considering four different materials covering both low yielding-high hardening alloys and high yielding-low hardening alloys, which are characterised by significant differences in the values of the Ramberg-Osgood exponent of the stress-strain constitutive law of the material.

Conclusion:
Finally, empirical formulations for predicting the non-dimensional ultimate flexural strength and the plastic rotation capacity of H-section aluminium beams under moment gradient have been provided as a function of the Ramberg-Osgood exponent and all the above non-dimensional parameters.
Konstantin Batiushkov "An Evening at Kantemir’s" (1816)
Authors: Levitt Marcus 
Published: December 2021

Konstantin Batiushkov’s “An Evening at Kantemir’s” (Vecher u Kantemira, 1816) is unique as a work of literature, a document of Russian intellectual history, and a cultural and artistic manifesto. The “Evening” takes its cue from the popular Enlightenment genre of “dialogues with the dead,” although Batiushkov brings together people who were contemporaries rather than widely separated historical figures, as was usual. In it, the poet Antiokh Kantemir (1708-44) challenges Montesquieu’s argument from The Spirit of Laws that Russia’s harsh climate has resulted in its alleged lack of civilization. Batiushkov was rewriting history with hindsight, and one of the charming aspects of the work is its slightly humorous and lightly ironic play with anachronism, as Batiushkov presents Kantemir as marvelously prophetic of the later successes of Russian literature. Typical is his interlocutor’s statement that “It is easier to believe that the Russians will storm Paris” than that Russia could produce a Lomonosov. Batiushkov himself was with the troops that took Paris in 1814, and the recent Russian victory was surely on readers’ minds as they read this piece. “An Evening at Kantemir’s” attempted to integrate the “new” Russian literature with the eighteenth-century “classicist” literary and Enlightenment tradition. It also illustrates Batiushkov’s faith in poetry as a fundamental way to advance the cause of national progress.

In the 2040, When today’s young teachers will be ending their teaching, it is reasonable to expect those global issues related to the environment and to cultural diversity to be a major focus in education. Now to help current students prepare to use modern technologies to bring student’s respect closer for apparently distant lands and culture. So it is need of the society for new framework of curriculum should be based on collaboration of universities, socirty and other organizations. There are some reasons of global dimensions in education.
•	The content for education is becoming global.
•	Modern technology is being used to increase access to education on a global scale.
•	Global issues can enhance education through the provision of stimulating rich contexts for critical reflection.
The Relative Contributions of Live and Recorded Online Mindfulness Training Programs to Lower Stress in the Workplace: Longitudinal Observational Study
Authors: Wolever Ruth Q , Finn Michael T M , Shields Denise 
Published: December 2021

Background
Despite numerous gaps in the literature, mindfulness training in the workplace is rapidly proliferating. Many “online” or “digital mindfulness” programs do not distinguish between live teaching and recorded or asynchronous sessions, yet differences in delivery mode (eg, face-to-face, online live, online self-guided, other) may explain outcomes.

Objective
The aim of this study was to use existing data from an online mindfulness solutions company to assess the relative contribution of live and recorded mindfulness training to lower perceived stress in employees.

Methods
Perceived stress and the amount of live and recorded online mindfulness training accessed by employees were assessed during eMindful’s One-Percent Challenge (OPC). The OPC is a 30-day program wherein participants are encouraged to spend 1% of their day (14 minutes) practicing mindfulness meditation on the platform. We used linear mixed-effects models to assess the relationship between stress reduction and usage of components of the eMindful platform (live teaching and recorded options) while controlling for potential reporting bias (completion) and sampling bias.

Results
A total of 8341 participants from 44 companies registered for the OPC, with 7757 (93.00%) completing stress assessments prior to the OPC and 2360 (28.29%) completing the postassessment. Approximately one-quarter of the participants (28.86%, 2407/8341) completed both assessments. Most of the completers (2161/2407, 89.78%) engaged in the platform at least once. Among all participants (N=8341), 8.78% (n=707) accessed only recorded sessions and 33.78% (n=2818) participated only in the live programs. Most participants engaged in both live and recorded options, with those who used any recordings (2686/8341, 32.20%) tending to use them 3-4 times. Controlling for completer status, any participation with the eMindful OPC reduced stress (B=–0.32, 95% CI –0.35 to –0.30, SE=0.01, t2393.25=–24.99, P<.001, Cohen d=–1.02). Participation in live programs drove the decrease in stress (B=–0.03, SE=0.01, t3258.61=–3.03, P=.002, d=–0.11), whereas participation in recorded classes alone did not. Regular practice across the month led to a greater reduction in stress.

Conclusions
Our findings are in stark contrast to the rapid evolution of online mindfulness training for the workplace. While the market is reproducing apps and recorded teaching at an unprecedented pace, our results demonstrate that live mindfulness programs with recorded or on-demand programs used to supplement live practices confer the strongest likelihood of achieving a significant decrease in stress levels.

Choice, Purchase Decision and Post-Purchase Dissonance: The Social Media Perspective
Authors: Mensah Kobby , Boateng Dankwah Justice , Mensah Gilbert , Masope-Crabbe Judith Aku 
Published: December 2021

Social media tools have emerged as an imperative source of information for customers. However, the relationship between information volume on social media and consumer choice quality remains blurred in literature. The study sought to examine the relationship between choice overload on social media and product choice quality, and how choice quality influences post-purchase dissonance. The study employed a positivist research paradigm and an explanatory design to examine the relationship between the various constructs. Using a purposive sampling method, Responses from 249 respondents were quantitatively analyzed. Structural equation modeling (SEM) was utilized. The outcome revealed a direct significant effect of choice overload on poor choice quality and a strong positive association between choice quality and post-purchase dissonance using social media tools. The distinctiveness of the study adds to the existing literature by extending the current understanding of post-purchase dissonance and consumer behavior in general.
Bark pitch in the Early Neolithic of Central Europe
Authors: Kotova Nadezhda , Stadler Peter , Goslar Tomasz 
Published: December 2021

The Linear Pottery people in 5670-5000 BC at the Brunn sites in Austria produced birch and beech bark pitches. Big globular vessels and closed high bowls could have been containers for the production and storage of this substance. Miniature vessels with a handle for hanging had contained small portions. Bark pitch as an adhesive for the repair of pottery and in the construction of big idols is also testified, as is the application of this material in decoration of vessels and idols, where bark pitch was a matrix for inlaying with grains or stones and creation of a contrasting black colour in linear ornamentation. Radiocarbon dating of bark pitch now is one of the most reliable materials for age determination of the Neolithic objects.
Logboat Discovered in Lake Lubanowo, Western Pomerania
Authors: Kontny Bartosz 
Published: December 2021

The paper presents a logboat found by an expedition from the University of Warsaw in Lake Lubanowo (northwestern Poland) during an underwater archaeological survey in 2020. It is the first logboat made of beech wood (Fagus sylvatica) registered in the area of Poland. The conventional radiocarbon date is 2350±30 BP; thus, the vessel may be attributed to the Jastorf or Pomeranian culture, as it was found in the border area between the territories of both units. Only a few logboats are known from the period preceding the Middle Ages in Poland. Other untypical traits are a transom, and a carefully formed beak-shaped bow. In the prow there is a rectangular hollow with a circular perforation inside of unclear function. One may consider it a fastening of an outrigger or other kind of floating attachment but also perhaps that the bow slot was intended either for a figurehead, for mooring, or to hold a torch during night-time fishing, or even functioned as a ‘stick-in-the-mud’ – type anchor.

Sociedade dividida, o feminino em disputa
Authors: Arce Carolina Assunción Oliveira , Penna Mariana Affonso 
Published: December 2021

O artigo reflete acerca dos projetos em disputa manifestos por um lado na organização anarco-feminista espanhola Mujeres Libres, por outro na Sección Femenina de la Falange, alinhada ao fascismo. Coletividades antagônicas, estas organizações se confrontaram em escritos e ações durante a Guerra Civil Espanhola, apresentando concepções opostas acerca do “lugar” a ser ocupado pela mulher na sociedade. Assumindo como ponto de partida as publicações produzidas por estes agrupamentos durante os anos de guerra, o manuscrito investiga o tratamento dado a temas como a sexualidade feminina, família, maternidade, espaço público e trabalho doméstico. Frente a ascensão do fascismo na Espanha após a queda da República, subverter ou aprofundar o papel tradicional atribuído à mulher fez parte de uma disputa, literalmente de vida ou morte para muitas.
