The chapter deals with issues related to the construction and development of the digital economy in one particular region: Republic of Armenia. This country is considered the digital sector of which may become the largest in the country in the next five years. The digital revolution affects all areas of the Armenian economy. Prior to this, the Armenian economy was known as the mining industry, a food producer, and a food. Today, according to statistics, Armenia's leading mining and energy companies are already one step ahead of their colleagues in the economically successful implementation of digital technology. Naturally, in such successes of digital transformations, there are key components. The authors hope that the examples of development and thought about the driving springs of these transformations, chosen in consideration of the interests of the development of the Russian digital economy, can be interesting and useful for Russian enterprises that have started their digital transformations.
Smart Cities in Sub-Saharan Africa
Authors: Chirisa Innocent , Matamanda Abraham Rajab
Published: January 2019

The aim of this chapter is to interrogate and diagnose the concept of smart cities as it has been applied to Sub-Saharan Africa (SSA) in a bid to decrypt the opportunities and challenges characterizing its manifestation in space and actuality. The chapter is a product of the critical engagement of scholarly work that compares the best practices in the development and promotion of the smart city concept against those practices that are antithetical and retrogressive in light of this good cause. To crystallize the realities, the chapter makes use of case studies that speak to these contrasting experiences. Case studies in SSA reveal differential practices with South Africa emerging as a country doing very well relative to others in the region. Some cities, especially the small and intermediate ones, fail to break even in terms of the revenue collections. This is partly because they have failed to attract investment in the form of industries or retain them because of politically induced instabilities.

Published: January 2019

Climate change is an actual fact setting off an imbalance in many living systems. Among these affected systems, water is a major essential element in the globe and in every existing living being. Therefore, several complications have been stated to occur, following water scarcity and water flood in many regions of the world, which make of them a global major threat of water security. The global disease burden is an additional factor that appeals to serious interventions worldwide in order to alleviate the water scarcity and water flood-related effects.
Using Critical Literacy Skills to Support Civic Discourse
Authors: Augustine Tami A. , Redman Daniel P.
Published: January 2019

A central focus of social studies education is to help students develop into informed and active citizens. Central to the practice of citizenship is the ability to engage in civic dialogue. Informed by the work of Kumashiro and Wolk, this chapter examines the role of critical literacy in moving social studies instruction beyond traditional, teacher-centered approaches to emphasize multiple and conflicting perspectives, inquiry skills, and civic discourse. In order to honor the multiple and conflicting perspectives present in any event, the use of critical literacy examines such questions as who is being represented? and who is speaking for whom? These questions serve to problematize American and Western-centric approaches to social studies education that serve to reinforce the hegemonic discourse too often evident in social studies classrooms to engage students in richer learning experiences and provide them with the skills and dispositions necessary to become active citizens.
Expanding the Curriculum With Creativity
Authors: Hinchman Timothy
Published: January 2019

Standardized education and narrow curriculum testing reduces students' abilities to critically think and creatively solve real-world problems. Although public policy emphasizes these important and practical skills, they have not adequately manifested in United States classrooms. They are instead filled with shallow prescribed curriculum that fails to inspire and guide students to think creatively. Science education provides a unique opportunity to engage students by solving real problems through flexible co-constructed supportive environment.
Brand Management and Media Gatekeeping
Authors: Miliopoulou Georgia-Zozeta , Cossiavelou Vassiliki
Published: January 2019

This chapter examines the brand manager's point of view on content marketing and brand management in the social media. Using the filters of media gatekeeping, the authors study Greek executives' views and practices in local and multinational firms and agencies. Findings indicate that gatekeeping still prevails. The dipole between control and security on the one hand, and openness and dialog on the other, determines all decision-making processes. A standardization of practices is observed, especially around brand communities and content publishing, as well as a need for control and risk avoidance. Global brands rely on headquarter-provided content requesting approvals for any modification. Local brands tend to outsource and monitor content calendars. Most brands consider what to release rather than what not to. They maintain a narrow, campaign-oriented mindset that reflects traditional practices and have not embraced the requirements for transparency and openness that prevail in the social media environment.
Digital Forensics and Cyber Law Enforcement

Published: January 2019

Security, safety, and privacy are of paramount importance to anyone who likes to crawl on the web. Keeping the best interest of the internet users in mind, India has laid down very solid foundations to safeguard its people from cyberattacks and cyber terrorism. The word “cyber law” encompasses all the cases, statutes, and constitutional provisions that affect persons and institutions who control the entry to cyberspace, provide access to cyberspace, create the hardware and software that enable people to access cyberspace or use their own devices to go “online” and enter cyberspace. Cyber crimes are unlawful acts wherein the computer is either a tool or a target or both. Cyber crimes can involve criminal activities that are traditional in nature, such as theft, fraud, forgery, defamation, and mischief, all of which are subject to the Indian Penal Code.

How a Specific Task Was Developed Through Multimodal Narratives
Authors: Nzau Domingos Kimpolo
Published: January 2019

Multimodal narratives (MNs) in the teaching of science and technology seek to report many aspects of a pedagogical nature in a complete and holistic manner. This chapter shows how six teachers of physics, from Angolan elementary education, without adequate pedagogical or academic training to teach physics, specifically the Newtonian concept of force, worked on a task during an intensive teacher training course. The MNs documents the professional development of the teachers in particular showing how they appropriated a tool (a specific didactic model) that was object of the training. The results achieved, with the help of multimodal narratives to register the occurrences in the seminar, once again reveal that MNs are as valuable a pedagogical tool in teachers' teaching practices as in their professional development (PD).
Researching Language and Semiotic Registers in Chemistry Lessons Using Multimodal Narratives
Authors: Maria Carolina José
Published: January 2019

The main objective of this chapter is to extend the discussion of language and the use of semiotic registers in chemistry lessons. Audio and video recordings, students' notebooks, photographs of content, and activities recorded on the blackboard in chemistry lessons for high school students taught in a public school in the interior of the State of São Paulo enabled the construction of multimodal narratives (MNs). The qualitative analysis of the MNs allowed the identification and understanding of the semiotic registers present in eight lessons conducted by a chemistry teacher. The study revealed several semiotic registers present in the lessons, but there is little exploration of the processes of conversion between semiotic registers by the teacher and therefore by the students. The use of different semiotic registers without the necessary understanding of them can result in difficulties in the teaching and learning processes of chemical concepts.
A Structural Evaluation of University Brand Equity Dimensions: Evidence from Private Indian University
Authors: Kaushal Vikrant , Ali Nurmahmud
Published: January 2019

The purpose of this article is to employ brand equity concepts to higher education. In doing so, the effects of certain dimensions, namely: university image, perceived quality, perceived value, and student satisfaction, on student loyalty are examined. A survey of 438 students enrolled in various programs was conducted on a large private university in north Indian state of Punjab. To arrive at an acceptable model, structural equation modelling was used and various hypotheses were tested. In the sampled data it was found that unlike theoretical indications, perceived quality was not found to be influencing student loyalty, moreover satisfaction only showed diminutive impact. However, perceived value emerged as the most important dimension in affecting students' loyalty behaviour. The study also highlights vital implications, limitations and scope of further studies.
An Empirical Analysis of an Organizational Continuum in a Japanese Accounting Cloud Service
Authors: Mizuno Yutaka , Odake Nobutaka
Published: January 2019

The purpose of this article is to clarify an organizational continuum of a technological platform development in a Japanese accounting cloud service. The authors continuously have been studying an accounting cloud service, which adopts two-sided markets structure and freemium business model. As the results, the authors obtain three findings. First, the Japanese accounting cloud service, which runs its business with regional banks in retail banking, has been exploiting its platform into partners' customers. Second, it has been building up from a supply-chain platform to an industrial platform in four years since its entrepreneurship. Third, it has been transforming its cloud-to-cloud service connections from weak-tied interfaces to its own strong-tied interfaces. Therefore, starting-up cloud service providers should not only utilize weak-ties to establish a structural hole, but also should develop its own strong-ties and indirect ties to tighten upon its two-sided markets structure in its cloud ecosystem.
A Case for Using Blended Learning and Development Techniques to Aid the Delivery of a UK Cybersecurity Core Body of Knowledge
Authors: Bird David A , Curry John
Published: January 2019

This article explores the UK's current approach in addressing the cybersecurity skills gap championed by the National Cyber Security Strategy. There have been progressive and elaborate steps taken in the UK toward professionalization of the cybersecurity field. However, cybersecurity knowledge has been labelled as inconsistent when a cybersecurity Chartered status is being proposed. The objective of this analysis was to apply an academic lens over the UK's voyage towards the establishment of a cybersecurity profession. It has been an ambitious but complex endeavor that at times has had alterations of course. Learning from this experience, a blended learning and development approach is now recommended underpinned by an overarching core knowledge framework. Such a framework could join up the existing silos of learning and development activities to benefit from, and build upon, a coherent core knowledge-base for the community. It is argued that this will provide a more satisfactory outcome to enhance the UK's cybersecurity capability on the road to a cybersecurity profession.
Theory Driven Modeling as the Core of Software Development
Authors: Osis Janis , Nazaruka (Asnina) Erika
Published: January 2019

Some experts opine that software is built in a primitive way. The role of modeling as a treatment for the weakness of software engineering became more important when the principles of Model Driven Architecture (MDA) appeared. Its main advantage is architectural separation of concerns. It showed the necessity of modeling and opened the way for software development to become an engineering discipline. However, this principle does not demonstrate its whole potential power in practice because of lack of mathematical accuracy in the very initial steps of software development. The sufficiency of modeling in software development is still disputable. The authors believe that software development in general (and modeling in particular) based on mathematical formalism in all of its stages and together with the implemented principle of architectural separation of concerns can become an important part of software engineering in its real sense. They propose the formalism by topological modeling of system functioning as the first step towards engineering.

Published: January 2019

Improving the performance of e-learning services to provide a scalable and effective e-learning system is a big challenge for the educational organizations. The e-learning system faces many challenges in pedagogical services (e.g. learning design and learning content problems), and technical services (e.g. resource provisioning and financial cost). This article presents an e-learning environment based on cloud computing (PCLE) in attempt to enhance the e-learning services' by customizing the contents of the course's material depending on the students' knowledge, experiences, and requirements. Also, the system focuses on supporting and achieving reusability, interoperability, adaptation and personalization in order to overcome the passive role of the student and transfer it into an interactive and useful participation. On the other hand, PCLE is built over the cloud computing environment trying to overcome the traditional web-hosting challenges as scalability, availability, and cost.

The Keap1–Nrf2 system plays a pivotal role in the oxidative stress response by inducing a number of cytoprotective genes. Under stress, damaged epithelial cells release cytokines that activate type 2 innate lymphoid cells (ILC2s), which mediate the allergic immune response. In this article, we investigated the role of the Keap1–Nrf2 pathway in ILC2 homeostasis and allergic inflammation using Nrf2 knockout mice. ILC2s from Nrf2-deficient mice showed a transient, upregulated IL-33 response and underwent hyperproliferation in response to a combined stimulation of IL-33 with IL-2, IL-7, or TSLP. This enhanced proliferation was correlated with an increased activation of downstream signals, including JAK1, Akt, and Erk1/2. In contrast, activating Nrf2 with a chemical inducer (CDDO-Im) decreased the viability of the wild-type but not of the Nrf2-deficient ILC2s. This effect on viability resembled that exerted by the corticosteroid dexamethasone; however, unlike the latter, the Nrf2-dependent cell death was mediated by neither caspase 3–dependent apoptosis nor necroptosis. Using a mouse intratracheal IL-33 administration allergy model, we found that the activation of Nrf2 by CDDO-Im in vivo decreased the number of pulmonary ILC2s and eosinophils. These findings indicated that Nrf2 is an important regulator of the allergic response by determining the survival and death of ILC2s, and these findings suggest that Nrf2 activation is a potential therapeutic strategy for steroid-resistant allergy alleviation.
Acquired tracheoesophageal fistula repair, due to prolonged mechanical ventilation, in patient with double incomplete aortic arch
Authors: Zampieri Davide , Pangoni Alessandro , Marulli Giuseppe , Rea Federico
Published: January 2019

We report a case of the repair of an acquired benign tracheoesophageal fistula (TEF) after prolonged mechanical invasive ventilation. Patient had an unknown double incomplete aortic arch determining a vascular ring above trachea and esophagus. External tracheobronchial compression, caused by the vascular ring, increasing the internal tracheoesophageal walls pressure determined by endotracheal and nasogastric tubes favored an early TEF development. The fistula was repaired through an unusual left thoracotomy and vascular ring dissection. TEFs are a heterogeneous group of diseases affecting critically ill patients. Operative closure is necessary to avoid further complications related to this condition. Pre-operative study is mandatory to plan an adequate surgical approach.
A case of bleomycin-induced lung toxicity
Authors: Tetikkurt Cuneyt , Ongel Deniz , Tetikkurt Seza
Published: January 2019

A 64-year-old female was admitted for dry cough, dyspnea, fever, loss of appetite, and weight loss. Past medical history revealed scoliosis, cholecystectomy, and Hodgkin lymphoma. ABG values were: pH: 7.42, pCO2: 40.2 mm Hg, pO2: 61.4 mm Hg. Chest CT showed cystic lesions, emphysema, ground glass, and reticular opacities. ABG values worsened under 8L/min nasal oxygen. The patient underwent bilevel positive airway pressure (BiPAP) and methylprednisolone 60 mg/day bid was commenced. The final diagnosis was respiratory insufficiency due to bleomycin toxicity. The patient deceased on the sixth day after transfer to the intensive care unit. Bleomycin is an effective chemotherapeutic agent used for Hodgkin lymphoma treatment. It causes significant lung toxicity in half of the patients. Clinicians should always remember that bleomycin toxicity may lead to fatal complications in patients with comorbid conditions. We present this case to remark the possible consequences of bleomycin toxicity and the precautions taken to preclude bleomycin-induced pulmonary complications are discussed.
The impact of gender in cardiovascular medicine: Lessons from the gender/sex-issue in heart failure
Authors: Marra Alberto M. , Salzano Andrea , Arcopinto Michele , Piccioli Lucrezia , Raparelli Valeria
Published: January 2019

Heart Failure (HF) is a major healthcare issue, given its high prevalence and incidence, the rate of comorbidities, the related high health-care costs and its poor outcome. In the last years mounting evidence revealed several differences between men and women affected by this clinical condition. Apart from the well-known difference in phenotype (HF with reduced ejection fraction (HFrEF) occurs more commonly in men, and HF with preserved ejection fraction (HFpEF) is more frequent in women) other relevant sex-related issues dwell upon epidemiology, presentation, risk stratification and management. These differences shed new lights on the possibility to consider HF as a prototype of the impact of gender/sex issue in cardiovascular medicine. A call for action and future strategies might help in the achievement of a cleaver patient-care.

Behavioral effects of the neurotoxin ß-N-methylamino-L-alanine on the mangrove rivulus (Kryptolebias marmoratus) larvae
Authors: Carion Alessandra , Hétru Julie , Markey Angèle , Suarez-Ulloa Victoria , Frédéric Silvestre
Published: January 2019

Mangrove rivulus, Kryptolebias marmoratus, is a hermaphrodite fish capable of self-fertilization. This particularity allows to naturally produce highly homozygous and isogenic individuals. Despite the low genetic diversity, rivulus can live in extremely variable environments and adjust its phenotype accordingly. This species represents a unique opportunity to clearly distinguish the genetic and non-genetic factors implicated in adaptation and evolution, such as epigenetic mechanisms. It is thus a great model in aquatic ecotoxicology to investigate the effects of xenobiotics on the epigenome, and their potential long-term impacts. In the present study, we used the mangrove rivulus to investigate the effects of the neurotoxin ß-N-methylamino-L-alanine (BMAA) on larvae behaviors after 7 days exposure to two sub-lethal concentrations. Results show that BMAA can affect the maximal speed and prey capture (trials and failures), suggesting potential impacts on the organism’s fitness.

Impacts of climate change and emissions on atmospheric oxidized nitrogen deposition over East Asia
Authors: Zhang Junxi , Gao Yang , Leung L. Ruby , Luo Kun , Liu Huan , Lamarque Jean-Francois , Fan Jianren , Yao Xiaohong , Gao Huiwang , Nagashima Tatsuya
Published: January 2019

Abstract. A multi-model ensemble of Atmospheric Chemistry and Climate Model
Intercomparison Project (ACCMIP) simulations is used to study the atmospheric
oxidized nitrogen (NOy) deposition over East Asia under
climate and emission changes projected for the future. Both dry and wet
NOy deposition show significant decreases in the 2100s under
RCP4.5 and RCP8.5, primarily due to large anthropogenic emission reduction
over both land and sea. However, in the near future of the 2030s, both dry
and wet NOy deposition increase significantly due to
continued increase in emissions. Marine primary production from both dry and
wet NOy deposition increases by 19 %–34 % in the
2030s and decreases by 34 %–63 % in the 2100s over the East China
Sea. The individual effect of climate or emission changes on dry and wet
NOy deposition is also investigated. The impact of climate
change on dry NOy deposition is relatively minor, but the
effect on wet deposition, primarily caused by changes in precipitation, is
much higher. For example, over the East China Sea, wet NOy
deposition increases significantly in summer due to climate change by the end
of this century under RCP8.5, which may subsequently enhance marine primary
production. Over the coastal seas of China, as the transport of
NOy from land becomes weaker due to the decrease in
anthropogenic emissions, the effect of ship emissions and lightning emissions
becomes more important. On average, the seasonal mean contribution of ship
emissions to total NOy deposition is projected to be
enhanced by 24 %–48 % and 3 %–37 % over the Yellow Sea and
East China Sea, respectively, by the end of this century. Therefore,
continued control of both anthropogenic emissions over land and ship
emissions may reduce NOy deposition to the Chinese coastal
seas.
High-resolution Beijing MST radar detection of tropopause structure and variability over Xianghe (39.75° N, 116.96° E), China

Published: January 2019

Abstract. As a result of partial specular reflection from the atmospheric stable layer, the radar tropopause (RT) can simply and directly be detected by VHF radars with vertical incidence. Here, the Beijing MST radar measurements are used to investigate the structure and the variabilities of the tropopause in Xianghe, China with a temporal resolution of 0.5 hour from November 2011 to May 2017. High-resolution radar-derived tropopause is compared with the thermal lapse-rate tropopause (LRT) that defined by the World Meteorological Organization (WMO) criterion from twice daily radiosonde soundings and with the dynamical potential vorticity tropopause (PVT) that defined as the height of 2 PVU surface. During all the seasons, the RT and the LRT in altitude agree well with each other with a correlation coefficient of ≥ 0.74. Statistically, weaker (higher) tropopause sharpness seems to contribute to larger (smaller) difference between the RT and the LRT in altitude. The RT agrees well with the PVT in altitude during winter and spring with a correlation coefficient of ≥ 0.72, while the correlation coefficient in summer is only 0.33. As expected, the monthly mean RT and LRT height both show seasonal variations. Lomb-Scargle periodograms show that the tropopause exhibits obvious diurnal variation throughout the seasons, whereas the semidiurnal oscillations are rare and occasionally observed during summer and later spring. Our study shows the good capability of the Beijing MST radar to determine the tropopause height, as well as present its diurnal oscillations.

Abstract. To study key processes of the water cycle, two special observation periods (SOPs) of the Hydrological cycle in the Mediterranean experiment (HyMeX) took place during the autumn 2012 and winter 2013. The first SOP aimed to study high precipitation systems and flash-flooding in the Mediterranean area. The AROME-WMED (West-Mediterranean) model (Fourrié et al., 2015) is a dedicated version of the mesoscale Numerical Weather Prediction (NWP) AROME-France model 5 which covers the western Mediterranean basin providing the HyMeX operational centre with daily real-time analyses and forecasts. These products allowed adequate decision-making for the field campaign observation deployment and the instrument operation. Shortly after the end of the campaign, a first re-analysis with more observations was performed with the first SOP operational software. An ensuing comprehensive second re-analysis of the first SOP which included field research observations (not assimilated in real-time), and some reprocessed observation datasets, was made with AROME-WMED. Moreover, a more recent version of the AROME model was used with updated background error statistics for the assimilation process. This paper depicts the main differences between the real-time version and the benefits brought by HyMeX re-analyses with AROME-WMED. The first re-analysis used 9 % of additional data and the second one 24 % more compared to the real-time version. The second re-analysis is found to be closer to observations than the previous AROME-WMED analyses. The second re-analysis forecast errors of surface parameters are reduced up to the 18-h or 24-h forecast range. In the mid and in the upper troposphere, upper-level fields are also improved up to the 48-h forecast range when compared to radiosondes. Integrated Water Vapour comparisons indicate a positive benefit for at least 24 hours. Precipitation forecasts are found to be improved with the second re-analysis for a thresholds up to 10 mm/24-h. For higher thresholds, the frequency bias is degraded. Finally, improvement brought by the second re-analysis is illustrated with the Intensive Observation Period (IOP 8) associated with heavy precipitation over Eastern Spain and South of France.
Error propagation in spectrometric functions of soil
organic carbon
Authors: Ellinger Monja , Merbach Ines , Werban Ulrike , Ließ Mareike
Published: January 2019

Abstract. Soil organic carbon (SOC) plays a major role concerning the chemical, physical and biological soil properties and functions. To get a better understanding how soil management affects the SOC content, the exact monitoring of SOC on long-term field experiments (LTFE) is needed. Visible and near infrared (Vis-NIR) reflectance spectrometry is an inexpensive and fast possibility to enhance conventional SOC analysis and has often been used to predict SOC. For this study, 100 soil samples were collected at a LTFE in central Germany by two different sampling designs. Regression models were built using partial least square regression (PLSR). In order to build robust models, 10-fold cross-validation was used for model tuning and validation procedure. We analysed and discussed various aspects that influence the obtained error measure. A transparent and precise documentation of the model building and validation process, including the calculation of the error measure, is necessary in order to assess the model accuracy in a comprehensive way. This would be the first step to gain a standardized method for model building and validation procedure.
Effect of Salinity and PH on the Industrial Effluent Treatment by Activated Carbon: Modeling of the Kinetic Adsorption and Equilibrium Isotherms
Authors: Mohamed E. F. , Awad G. , Andriantsiferana C. , Delmas H.
Published: January 2019

In recent years, interest has been focused on the removal of phenols from contaminated by using a variety of purification techniques. Adsorption of bio-industrial effluent on commercial activated carbon S23 was investigated at ambient conditions. In this wok, phenol and p-hydroxyl benzoic acid (PHBA) was studied as an example of the organic compounds present in the industrial effluent. The effect of temperature, pH, and the presence of inorganic salt NaCl on the pollutants adsorption were studied to give further comprehension of the optimal conditions of the organic compounds adsorption onto activated carbon. It was noted that the increase in temperature resulted in a decrease in phenols adsorption capacity by S23. Lower phenol adsorption was also observed at the solution pH 2 and 10, whereas, favourable adsorption was reached at neutral solution pH, and the coexisting inorganic salt NaCl exerts slightly positive effect on the adsorption process. The isotherms obtained at pH 2.2 and 3.5 (non-buffered solution) are very similar and showed a higher adsorption capacity compared with that obtained at pH 7 and 10 for PHBA which is more adsorbable than phenol. The kinetic of the adsorption processes can be better represented by the pseudo-second order. The results showed also that the total organic carbon (TOC) of the industrial effluent reduced for about 20 %. Freundlich, Langmuir and Jovanovic adsorption models were used for mathematical description of adsorption equilibrium of phenols. The results showed that the experimental data fitted very well to the Freundlich and Jovanovic models.

Esta investigación es un análisis en el marco de la teoría queer de relaciones internacionales sobre las acciones ejecutivas federales relativas a la diversidad sexual en México. Se postula que formas particulares de entender quién es el "homosexual" se trasladaron a una agenda doble entre lo que se predica a nivel internacional y lo que se hace en la esfera local. Se concluye que México construyó por medio de su diplomacia queer una figuración del “homosexual normal” que era incompatible con la diversidad de la comunidad LGBT del país

The research conducted is a descriptive analysis of quantitative data to determine information on the interests of halal certificates in the eyes of business actors. By using a questionnaire as an instrument. The sample used was 101 business actors with different lengths of operation. The results showed that presents the high actors who have given halal label on the length effort than or equal to 2 years and less than five years, with a percentage of 64.10%. This shows that most business actors who are very concerned with labeling their products are usually those who have run their business more than or equal to 2 years but less than 5 years.

Redeveloping sites to accommodate housing or new economic activities is a major urban policy challenge. This problem belongs to the class of NP-hard problems. In this paper, we present an attractive mixed integer nonlinear programming formulation for the transportation network and land use problem. We first introduce a new useful nonlinear formulation of this challenging combinatorial optimization problem. Then, an alternative to considering a linearity of the constraints is to reformulate the problem as a new exact, compact discrete linear model. The problem is solved by our new algorithm and numerical results are presented for a number of test problems in academics instances.

Distance education is a form of education in which students don’t need physically attend the place of study. students receives the study material (personally, by mail, email or other possibilities offered by the Internet), allowing the educational act to employ new techniques and learning strategies focused on the student, thus promoting self- teaching and self-management, it is a flexible and self-directed education, whose main tools are communication technologies. This paper aims to discuss how learning occurs, especially in distance education, what it means to learn from this educational modality. In order to delimit the conceptual framework, we initially start with what education is and how learning is generated in this mediated process. The conclusions allow us to infer that distance learning requires the conditions and capacities of the teacher to promote independent study, of the student's self-regulation and self-regulation, in order that this can control their learning process.

Political and administrative corruption in the Netherlands; state of affairs 2018

The most recent extensive study on political and administrative corruption in The Netherlands dates back to 2005 (Huberts & Nelen, 2005). Afterwards various studies have been conducted on related subthemes and areas. In this contribution, the state of affairs regarding political and administrative corruption – and the responses to them – in The Netherlands in 2018 is described, based on the results of these studies. Starting with an overview of the nature and severity of political and administrative corruption, the focus shifts to relevant developments in the control and prevention of corruption, partly addressing the causes of the phenomenon.

Parents’ knowledge of risk factors of caries and the need to visit a dentist for routine check-ups affect the children’s dentition status in the future. Lack of activities in this field often results in premature loss of deciduous teeth and it adversely affects a position of permanent teeth undergoing eruption. Aim. To compare the dentition status of children under the care of an orthodontist and of children who are not covered by orthodontic care, and to assess the effects of parents’ education on the dentition status of their children. Material and methods. The study included 232 children from primary schools in Lublin (110 boys and 122 girls). The age of subjects was between 6 years to 8 years and 11 months. The study included a survey questionnaire for parents and a clinical examination of children. The number of DMFT and dmft was calculated in each child based on a clinical examination. In the study population the incidence of caries (Fp) and mean numbers of dmft (for deciduous teeth) and DMFT (for permanent teeth) were calculated. Results. In the study group of children 12.93% were receiving orthodontic treatment with removable appliances, 10.78% were supervised by an orthodontist or were orthodontic treatment scheduled, and 75.86% of studied children had never been at an orthodontist’s office. One person (0.43%) did not provide answers to questions asked. Children receiving orthodontic care had significantly lesser carious defects in their deciduous teeth compared to children who were not receiving such care. Conclusions. 1) Providing orthodontic care to children had a beneficial effect on their dentition. 2) It is worth to pay more attention to prophylaxis of caries and to supervise the process of dentition replacement. 3) It is necessary to promote health-promoting education regarding caries and malocclusions among parents.

Effects of premature loss of deciduous teeth on the morphology and functions of the masticatory organ. Literature review
Authors: Wojtaszek-Lis Julita , Regulski Piotr , Laskowska Małgorzata , Zadurska Małgorzata
Published: January 2019

Premature loss of a deciduous tooth is its loss 3 to 4 years before its physiological replacement, in other words – one year before the date of physiological resorption of its roots. The most common reasons for premature loss of deciduous teeth include complications of caries such as: pulp gangrene, periodontitis, inflammation of the periapical area, periapical lesions, abscesses, and osteitis. Mechanical traumas and cysts belong to other reasons. Direct consequences of premature loss of a deciduous tooth include inhibition of growth of the alveolar process bone of the maxilla or alveolar part of the mandible in the area where a tooth is missing. Presence of space in the dental arch leads to various dental displacements such as tooth displacement along the arch, rotations, inclinations. It leads to dental abnormalities, including secondary crowding, dental abnormalities associated with time and place of eruption of permanent teeth, arch midline shift, and Godon’s effect. Consequences of premature loss of deciduous teeth also include worsening of pre-existing malocclusions and dysfunctions of the masticatory organ associated with chewing, speech and swallowing. Aim. The paper aimed to present consequences of premature loss of deciduous teeth and to determine indications for prophylactic treatment. Material and methods. A review of literature in Polish and English from the period 2006–2017 was performed using PubMed, PBL, Embase, Scopus databases. “Premature loss of deciduous teeth” was a key word. Results. Consequences of premature loss of various groups of deciduous teeth were presented and indications for prophylactic treatment were discussed based on literature collected. Conclusions. The analysis performed concluded that due to various consequences of premature loss of deciduous teeth orthodontic management is recommended in many cases in order to minimise consequences of premature loss of deciduous teeth.

Studies regarding development of the facial skeleton and understanding of morphogenetic background of various types of skeletal classes are important not only from a cognitive point of view, but also from a clinical one, in relation to treatment of patients according to a personal phenotype. Aim. This paper aimed to present a review of literature regarding development and growth of the facial skeleton in the aspect of skeletal classes. Material and methods. A review of the literature from the years 2001– 2016 was conducted using the PubMed database. Key words used to search for articles included: skeletal class development, skeletal class malocclusion development. Inclusion criteria were based on selection of original papers regarding development and growth of facial skeleton in the prenatal and postnatal period. Exclusion criteria included review papers and case reports. Results. Articles selected based on inclusion criteria indicate there are many reasons affecting a direction of morphogenesis of the facial skeleton and mutual correlations during development. It is possible to understand these processes as a result of distinguishing between growth and physical development in the prenatal and postnatal period. Important factors present in the prenatal period include, among others, the following: interactions of the Frontonasal Ectodermal Zone, shh proteins, fgf8 proteins and BMP signalling. Factors present in the postnatal period depend on structural, functional, anatomical, genetic and growth patterns interactions. The following factors affecting development of skeletal classes were analysed: sexual dimorphism, effects of masticatory muscles, permanent tooth eruption, and quality of the respiratory tract. Conclusions. Studies regarding development of the facial skeleton and morphogenetic background of various types of skeletal classes contribute to improvement of clinical aspects of treatment, according to a personal phenotype and any dysfunctions associated with the skeletal structure.
