Institutional Support of the Public-Private Partnership in the Republic of Poland
Authors: Lakhyzha Nykola , Yehorycheva Svitlana
Published: March 2020

The experience of the institutional support of public-private partnership in the Republic of Poland has been analyzed. It is noted that Poland was one of the first among the post-communist countries to implement a mechanism of public-private partnership. The peculiarities of the practice of realization of public-private partnership in Poland during the 1990s and its legal support were determined. The possibility of its development on the basis of general norms of civil, economic, administrative and other branches of law is emphasized. The process of development and adoption of separate laws on public-private partnership and their specific features are described. The essence of discussions about the need for creation of a special authorized body for regulation of public-private partnership, which was caused by the problems that arose from public and private partners during the conclusion and implementation of the relevant agreements, was disclosed. The modern components of organizational support for supporting the development of public-private partnership in Poland, their role and their inherent functions are revealed: the Department for Public-Private Partnerships of the Ministry of Investment and Development, similar departments in public administration bodies of different levels, the Public-Private Partnership Platform, Polish Entrepreneurship Development Agency, Institute of Public Private Partnership, private law firms, scientific and educational institutions. The necessity to improve the institutional support of public-private partnership, which is realized by the government of Poland as well, is stated. The content and significance of the latest program documents in this area that are intended to improve the process of administration the development of public-private partnership — the concept «The vision of sustainable development for Polish business 2050» and «Government policy in the field of development of public-private partnership» are characterized. The importance of using the experience of the Republic of Poland in the practice of public administration of the Ukrainian system of public-private partnership is emphasized.
The Will under the Roman Succession Law and its Reception in the Law of the Countries in the Period of the Middle Ages
Authors: Lozinska Svitlana
Published: March 2020

The article carries out the comparative analysis of the main criteria to the will in a succession law of the Roman State, in particular, concerning conditions of its reality, formal requirements to a circle of successors, procedures of drawing up and types of wills. It has been established the essence of the principle of freedom of the will. In the XIIth – XIIIth centuries in Western Europe one could fnd the frst codifed collections of laws, the reception of Roman Law, emergence of a municipal right, as well as extension of Canon Law. The Roman Law becomes one of the sources of the medieval right. It has been investigated the reception of legal norms of the will in a medieval Canon Law of Europe. With introduction of Christianity a part of property which belonged to the testator was ceased to be buried and burnt together with a corpse. Instead, it was distributed on charity for the beneft of soul of the dead. The Canon Law of wills was established based on jurisdiction of church and ecclesiastical courts, and the will was considered as the religious act of expression of the last will of the dead. Freedom of the will was considered as freedom to make contributions on religious and charitable affairs. As for the wills, the Roman Law was signifcantly complemented by canonists with two important institutes: an ex- ecutor of the will and appointment of the managing director to distribute property of the person who died without will. The Canon Succession Law enforced protection of interests of the wife of the dead and his children against deprivation of heritage by the testator. The successor was also granted the right to refuse inheritance accep- tance if duties which arose in this regard exceeded his/her opportunities. Thanks to the reception of Roman Law which took place in medieval Western Europe ca-nonists created the new right of wills — partially based on German-Christian institutes and partially on the classical Roman Succession Law which was known to church and was used by it long ago. If there was no will, the Roman Succession Law applied the norms similar to the institute of the German National Law, i.e. its main goal was to provide the successor of the head of the family. However the Ro- man Law defned legal aspects of inheritance much more broadly.
The Practice of the Supreme Court as an Indicator of the Defects in Legislation on Enforcement Proceedings
Authors: Stefanchuk Maryna
Published: March 2020

The current state of enforcement proceedings reform in Ukraine has been highlighted. It has been stated that its goal is to overcome the systemic problems of an ineffective enforcement of court judicial decisions. The practice of the Supreme Court on the enforcement of judicial decisions in Ukraine has been analyzed. It has been found that the Grand Chamber of the Supreme Court, which reviews the case if it contains an exceptional legal issue to ensure the development of law and the formulation of uniform law enforcement practice, has stated a significant number of gaps in the legislation of Ukraine on enforcement proceedings. It has been considered one of these exceptional legal problems in the sphere of enforcement proceedings concerning the defects in legislative regulation of relations in consolidated enforcement proceedings. On the basis of the study, it has been concluded that the practice of the Supreme Court is an indicator of the defects in legislation on enforcement in Ukraine in the form of consolidated enforcement proceedings, which consist of legal uncertainty in the regulation of the important elements of this legal institution. These gaps in the legislation should be addressed at the legislative level, and not remain subject of judicial lawmaking, as judicial practice is not stable. Moreover, it should be in accordance with the requirements of European institutions in the sphere of enforcement, according to which national legislation should contain a clear definition of the conditions for enforcement, the statutory enforcement provisions should be worked out clearly, avoiding the possibility for misinterpretation. Taking into account the doctrinal studies, as well as using the successful experience of other states, the strategic direction of improvement of the legislation of Ukraine in the sphere of enforcement should determine the need for a conceptual change in the system of enforcement with the transition to the monopoly of private executors or their dominant component in the system of enforcement agencies. The competence of the State Enforcement Service should be focused on the enforcement of judicial decisions in which one of the parties is a state.

Published: March 2020

Social interactions require quick perception, interpretation, and categorization of faces, with facial features offering cues to emotions, intentions, and traits. Importantly, reactions to faces depend not only on their features but also on their processing fluency, with disfluent faces suffering social devaluation. The current research used electrophysiological (EEG) and behavioral measures to explore at what processing stage and under what conditions emotional ambiguity is detected in the brain and how it influences trustworthiness judgments. Participants viewed male and female faces ranging from pure anger, through mixed expressions, to pure happiness. They categorized each face along the experimental dimension (happy vs. angry) or a control dimension (gender). In the emotion-categorization condition, mixed (ambiguous) expressions were classified relatively slower, and their trustworthiness was rated relatively lower. EEG analyses revealed that early brain responses are independent of the categorization condition, with pure faces evoking larger P1/N1 responses than mixed expressions. Some late (728- 880 ms) brain responses from central-parietal sites also were independent of the categorization condition and presumably reflect familiarity of the emotion categories, with pure expressions evoking larger central-parietal LPP amplitude than mixed expressions. Interestingly, other late responses were sensitive to both expressive features and categorization task, with ambiguous faces evoking a larger LPP amplitude in frontal-medial sites around 560-660 ms but only in the emotion categorization task. Critically, these late responses from the frontal-medial cluster correlated with the reduction in trustworthiness judgments. Overall, the results suggest that ambiguity detection involves late, top-down processes and that it influences important social impressions.

The role of parents in the professional choice of young people
Authors: Udovytska T. A. , Savokhina M. V.
Published: March 2020

The article deals with the analysis of parents’ role in young people’s professional choice. The main aspects of this impact, traditionally considered in literature on these kinds of problems, have been mentioned in this article. A typology of interaction between parents and children in the process of professional choice has been given, based on this analysis.
Moreover, the factors, which influenced the change of parents’ role in the professional choice of modern youth, have been considered in this article. These factors have led, on the one hand, to the increase of young people’s independence in choosing professions, which are quite new on the modern labour market and parents do not always know these professions. In addition, on the other hand, these factors have led to the decrease of the same independence, caused by the increase in the number of those who study on the contract basis, which is financially supported by parents.
Based on this analysis, contradictions in interaction between parents and children in the process of professional choice have been found.

Celebration of the 208th Anniversary of May Revolution
Authors: Alonso Alberto José
Published: March 2020

The article is devoted to the May Revolution in Argentina and the 25th anniversary of the opening of the representation of the Argentine Republic in Ukraine.
The May Revolution has its origins in the events of May 25, 1810. It was the day when the foundation act declaring the creation of the Argentine state was issued. Two hundred and eight years ago, the word “freedom” arose in the hearts of Argentines. Remembering the most significant moments of history, Argentines preserve and cherish their desire for peace and freedom.
Ukraine and Argentina are negotiating bilateral agreements on social security, extradition, mutual assistance in criminal and civil cases, tourism, cinematographic production, intellectual property protection, environmental safety. More than 50 bilateral agreements have already been signed by the two countries in recent years. The enhancement of cooperation is to be reiterated at the meetings of the Joint Commission for Economic and Trade Affairs in Buenos Aires. It is expected that those meetings would result in visits of delegations of Ukrainian businessmen to Argentina and vice versa.
The author draws attention to the unveiling of a commemorative sign dedicated to the father of the Argentine nation, General Don José de San Martín, in the garden square in front of the Embassy of the Argentine Republic to Ukraine.
The article also focuses on active efforts to spread the culture of Argentina through the Argentine House in Kyiv that offers a wide range of activities, including Argentine literature workshops, tango and folk dance classes, tourism seminars, movie screenings. The author argues that nothing brings people closer together than culture and concludes that relations between Ukraine and the Argentine Republic are at a high level.

Vietnam and Ukraine: Briliant Relations in New Period
Authors: Anh Tuan Nguyen
Published: March 2020

The article describes the development and strengthening of communication between Ukraine and Vietnam thanks to tireless work of many generations. Ukraine provided tremendous efficient moral and material assistance to Vietnam while it conducted struggle for peace and national independence as well as in the period of post-war national reconstruction. In the course of this war, thousands of Ukrainian advisors and military experts marched long distances throughout Vietnam to make their contribution to assisting the Vietnamese nation. Tens of thousands of Vietnamese, namely high-ranking officials in various fields, have been trained in Ukraine and obtained the necessary knowledge and skills. Ukrainians have made a significant contribution to the development of Vietnam.
Over the last 26 years, traditional friendship and all-round cooperation between the two states have transformed into a comprehensive partnership. That upshot is the establishment of a new development basis of Vietnamese-Ukrainian relations that were rapidly developing in all domains, including economy, politics, defense, trade, science, education, and humanitarian cooperation.
Ukraine is highly interested in developing cooperation with Vietnam, especially on those matters related to giving permission to Ukraine for vegetable exports to Vietnamese market. Ukraine also purports to deepen cooperation in the realm of machinery production, energy, in particular in projects of modernization, improvement or construction of new power plants in Vietnam. Besides, Vietnam is the only foreign state where Ukraine has its own port. Vietnamese and Ukrainian enterprises in the realm of agriculture, mining, IT, vessel construction, and footwear industry have concluded a range of agreements.
Keywords: Vietnam, cooperation, Ukraine, Vietnamese nation, comprehensive partnership, Vietnamese-Ukrainian agreements.

The purpose of this research is analizing the impacts of sandstone mining activities against erosion in Indragiri River, quality of Indragiri River water and local socio-economic conditions. Based on the reasearch, sand-stone mining in Indragiri River causes erosion so that the river body widened and the depth of the river is shallower due to sedimentation. Other than that, quality of Indragiri River water such as brightness, turbidity, TSS, DO and BOD5 including the polluted category. This is caused by sand-stone mining activities, waste from palm factory and gold mining along the Indragiri River. Socially and economically, the sand-stone mining activities have a positive impact in improve the living standards of local communities and have a negative impact on environmental quality
DO HIGHER HOUSE PRICES INDICATE HIGHER SAFETY? PRICE VOLATILITY RISK IN MAJOR CITIES IN TAIWAN
Authors: Chu Fang-Ni , Tsai I-Chun
Published: March 2020

This study investigates the housing market in Taiwan, an emerging market with relatively severe housing price inflation. Using data from the first quarter of 1991 to the second quarter of 2017 for four cities in Taiwan, this study compares the risk transmission and sources of their housing prices. The results reveal that Taipei−Taiwan’s main financial hub−has the highest house prices among the four cities but maintains the lowest risk. Thus, in terms of price volatility risk, Taipei has the safest housing market among the studied cities. Other studies have discussed the potential housing price bubbles in regions with high housing prices but have been unable to explain the continual overheating of the housing markets. The findings of this study reveal that despite having the highest housing prices and the greatest potential bubble, the Taipei housing market has the lowest fluctuation risk, making it the safest market in terms of housing investment. The results of this study imply that Taiwan’s economic development is excessively concentrated in Taipei, causing people to bear low returns and high risk when purchasing real estate in other areas, in turn increasing the continual imbalance between regional housing markets.
Dynamic Responses of Radiation Belt Electron Fluxes to Magnetic Storms and their Correlations with Magnetospheric Plasma Wave Activities

Published: March 2020

To investigate the responses of Earth’s radiation belt electrons during magnetic storms and their correlations with magnetospheric chorus and plasmaspheric hiss waves, a statistical analysis is conducted using high-quality Van Allen Probes measurements during 68 isolated geomagnetic storms from 2012 September to 2017 December. The variations of radiation belt electron fluxes exhibit high dependence on electron kinetic energy, L-shell, and geomagnetic storm magnitude. It is found that the Increase-type events increase considerably with L-shell at L ∼ 3.0–5.0, the Decrease-type events tend to occur more frequently at L = 3.7–4.7 for <1 MeV electrons during weak storms and at L = 3.5–6 for >1 MeV electrons during moderate storms, and the No-change-type storm events are relatively dominant for extremely high-energy (>5.2 MeV) electrons. Superposed epoch analyses for the three types of storm events indicate that compared to relativistic (604 keV) electrons, ultrarelativistic (3.4 MeV) electron flux enhancements are more likely in association with elevated solar wind pressure during the storm initial phase, enhanced southward initial mass function Bz during the storm main phase, and prolonged high solar wind speed during the storm recovery phase. It is also shown that the dynamic variations of relativistic (604 keV) electron fluxes are closely connected to the activity level of chorus waves, but the three variation categories of ultrarelativistic (3.4 MeV) electrons have basically comparable intensities of chorus waves possibly due to the loss mechanisms becoming more dominate for their No-change-type or Decrease-type events. From a statistically observational perspective, chorus waves act as a critical candidate for relativistic electron acceleration and plasmaspheric hiss as a viable cause for relativistic electron loss.

Published: March 2020

We present the second Open Gravitational-wave Catalog (2-OGC) of compact-binary coalescences, obtained from the complete set of public data from Advanced LIGO’s first and second observing runs. For the first time we also search public data from the Virgo observatory. The sensitivity of our search benefits from updated methods of ranking candidate events including the effects of nonstationary detector noise and varying network sensitivity; in a separate targeted binary black hole merger search we also impose a prior distribution of binary component masses. We identify a population of 14 binary black hole merger events with probability of astrophysical origin >0.5 as well as the binary neutron star merger GW170817. We confirm the previously reported events GW170121, GW170304, and GW170727 and also report GW151205, a new marginal binary black hole merger with a primary mass of

that may have formed through hierarchical merger. We find no additional significant binary neutron star merger or neutron star–black hole merger events. To enable deeper follow-up as our understanding of the underlying populations evolves, we make available our comprehensive catalog of events, including the subthreshold population of candidates and posterior samples from parameter inference of the 30 most significant binary black hole candidates.
Diffusive Shock Acceleration: Breakdown of Spatial Diffusion and Isotropy
Authors: Keshet Uri , Arad Ofir , Lyubarski Yuri
Published: March 2020

We point out that particles accelerated in a nonrelativistic shock of compression ratio r do not necessarily attain the standard, p = (r + 2)/(r − 1) spectral index. Previous derivations of the spectrum, based on the approximations of spatial diffusion or negligible anisotropy, are shown to rely on unjustified implicit assumptions. We prove analytically that the standard result is nevertheless valid in the limit of an isotropic medium. For an anisotropic medium, the problem generally requires a numerical treatment; the standard result remains valid as long as the anisotropy is not too strong, but p can substantially deviate from the standard result for sufficiently anisotropic scattering, even in the small-angle scattering limit. Additional spectral modifications, for example, by motions of scattering modes at intermediate optical depths from the shock, are discussed.
Detection of the Red Supergiant Wind from the Progenitor of Cassiopeia A

Published: March 2020

Cassiopeia A (Cas A) is one of the best studied young Galactic supernova remnants. While it provides a rare opportunity to study in detail the remnant of a supernova (SN) type IIb, questions remain regarding the nature of its progenitor, its mass-loss history, and its pre-SN evolution. Here we present an optical investigation of the circumstellar environment around Cas A and find clumpy and filamentary Hα emission nebulosities concentrated 10–15 pc (10′–15′) to the north and east. First reported by Minkowski as a faint H ii region, these nebulosities exhibit distinct morphological and spectroscopic properties relative to the surrounding diffuse emissions. Compared to neighboring H ii regions, these nebulae show stronger [N ii] 6548, 6583 Å and [S ii] 6716, 6731 Å emissions relative to Hα. We show that Cas A’s highest-velocity ejecta knots are interacting with some of the closest projected emission nebulae, thus providing strong evidence that these nebulae lie at the same distance as the remnant. We interpret these surrounding nebulosities to be the remains of the progenitor’s red supergiant wind, which accumulated against the southern edge of a large extended H ii region located north of Cas A. Our findings are consistent with the view that Cas A’s progenitor underwent considerable mass loss, first from a fast main-sequence wind, then from a slower, clumpy red supergiant wind, and finally from a brief high-velocity wind, like that from a yellow supergiant.
Extreme Ultraviolet and Soft X-Ray Diffraction Efficiency of a Blazed Reflection Grating Fabricated by Thermally Activated Selective Topography Equilibration
Authors: McCoy Jake A. , McEntaffer Randall L. , Miles Drew M.
Published: March 2020

Future observatories utilizing reflection grating spectrometers for extreme ultraviolet (EUV) and soft X-ray (SXR) spectroscopy require high-fidelity gratings with both blazed groove facets and custom groove layouts that are often fanned or feature a slight curvature. While fabrication procedures centering on wet anisotropic etching in monocrystalline silicon produce highly efficient blazed gratings, the precision of a nonparallel groove layout is limited by the cubic structure of the silicon crystal. This motivates the pursuit of alternative techniques to grating manufacture, namely thermally activated selective topography equilibration (TASTE), which uses gray-scale electron-beam lithography to pattern multilevel structures in resist followed by an optimized polymer thermal reflow to smooth the 3D patterns into continuous surface relief profiles. Using TASTE, a mold for a reflection grating with a periodicity of 400 nm and grooves resembling an asymmetric sawtooth was patterned in 130 nm thick poly(methyl methacrylate) resist on a silicon substrate over a 50 mm by 7.5 mm area. This structure was coated with 15 nm of gold by electron-beam physical vapor deposition using titanium as an adhesion layer and then tested for EUV and SXR diffraction efficiency at beamline 6.3.2 of the Advanced Light Source synchrotron facility. Results demonstrate a quasi-blaze response characteristic of a 27◦ blaze angle with groove facets smooth to 1.5 nm rms. Absolute peak-order efficiency ranges from 75% to 25%, while total relative efficiency measures ⪆90% across the measured bandpass of 15.5 nm > λ > 1.55 nm.
Spiders (Arachnida: Araneae) in the semideciduous Atlantic Forest: An ecological and morphological trait dataset for functional studies
Authors: Munévar Ana , Cardoso Pedro , Piñanez Espejo Yolanda , Zurita Gustavo Andres
Published: March 2020

The semideciduous Atlantic Forest is one of the most diverse ecosystems in the world with a great diversity of spiders. Most spider-related studies in this ecosystem focused on species richness and composition; however, little is known about their trait diversity (including morphological, ecological and/or physiological traits). Two main datasets were compiled to generate a complete record of spider traits for this ecosystem.

Here, we present two datasets about 259 species of spiders from the semideciduous Atlantic Forest of Argentina. The trait data set compiled information of morphological and ecological traits such as body size, femur length, ocular distance, foraging strategy, prey range, circadian activity and stratum preference; traits were assessed by species considering sexual dimorphism. The second dataset included information about phenology (season when spiders were collected), number of individuals assessed by species and presence/absence of spiders in the different sample sites. This dataset has high potential to help researchers in recording the state of a component of biodiversity (functional) and contributes with the study of ecosystem services and species conservation.
Cryptic diversity and range extension in the big-eyed bat genus Chiroderma (Chiroptera, Phyllostomidae)
Authors: Lim Burton K. , Loureiro Livia O. , Garbino Guilherme S.T.
Published: March 2020

Since the last systematic review ofChiroderma(big-eyed bats) more than two decades ago, we report on biodiversity surveys that expand the distribution and species diversity of this Neotropical genus. The Caribbean endemic speciesChiroderma improvisumis documented for the first time from Nevis in the northern Lesser Antilles. A broader geographic sampling for a molecular analysis identifies a paraphyletic relationship inChiroderma trinitatumwith respect toChiroderma doriae. Cis-Andean populations ofC. trinitatumare most closely related to the morphologically distinctive and allopatrically distributedC. doriaein the Cerrado and Atlantic Forest of Brazil and Paraguay. The sister taxon to this grouping includes trans-Andean populations ofC. trinitatum, which we recommend to elevate to species status asC. gorgasi. This is an example of a cryptic species becauseC. gorgasiwas previously considered morphologically similar toC. trinitatum, but more detailed examination revealed that it lacks a posterolabial accessory cusp on the lower second premolar and has a narrower breadth of the braincase. We provide an amended description ofChiroderma gorgasi.

L’objet du Liber sex principiorum d’après ses commentateurs (c. 1230-1337)
Authors: Girard Charles
Published: March 2020

L’article porte sur quatre questions généralement traitées au début des commentaires au Livre des six principes , à savoir : 1. De quelle discipline relève le traité ? 2. Quel est le sujet du traité et sous quel mode est-il considéré ? 3. Pourquoi forme-t-il un traité distinct des Catégories ? 4. Pourquoi y parle-t-on de « principes » ? Des commentaires, pour la plupart inédits, de la deuxième moitié du xiii e siècle et du début du xiv e siècle sont analysés.
La pulsion de mort : hypothèse, croyance ou supposition ?
Authors: Sédat Jacques
Published: March 2020

La pulsion de mort : hypothèse, croyance ou supposition ? L’hypothèse d’une pulsion de mort n’apparaît chez Freud qu’au terme de ses recherches sur la distinction indispensable entre pulsion de genre et pulsion sexuelle, ainsi que sur le rôle capital joué par la contrainte de répétition, issue de motions pulsionnelles. Il aborde en 1920 pour la première fois, dans Au-delà du principe de plaisir , l’« hypothèse » de la pulsion de mort qu’il situe avec précaution au niveau de la croyance. Dans divers textes ultérieurs, il revient prudemment sur cette notion qu’il désigne plus volontiers sous le nom de « pulsion de destruction », non sans lien avec la contrainte de répétition.
Diversidad y distribución de los endemismos de Asteraceae (Compositae) en la Flora del Ecuador
Authors: Rivero-Guerra A. O.
Published: March 2020

La familia Asteraceae está representada en la Flora de Ecuador por un total de 310 táxones endémicos. Están agrupadas en 4 subfamilias (Asteroideae, Barnadesioideae, Cichorioideae y Mutisioideae), 16 tribus y 89 géneros. Doscientas setenta y dos táxones (87,74%) restringen su hábitat a la región andina. Los niveles más altos de endemismos están asociados a los Andes, mayoritariamente desde el bosque andino alto hasta el páramo, y a las Islas Galápagos. Los géneros con mayor riqueza de endemismos son Mikania (26), Pentacalia (23), y Gynoxys (20). Tres géneros monotípicos son endémicos: Cyathomone, Idiopappus y Trigonopterum. Los géneros Darwiniothamnus, Kingianthus, Lecocarpus, y Scalesia también son endémicos. La diversidad de la familia se incrementa desde los 2000 m a 3000 m, alcanzando su mayor riqueza entre los 2900-3000 m, con dominancia de las plantas arbustivas (195 especies, 1 subespecie, 2 variedades) y herbáceas (97 especies). Ciento veinteseis especies tienen categoría de vulnerable, 90 están en peligro de extinción y 24 están en estado crítico de amenaza. Las temperaturas y precipitaciones medias anuales varían significativamente entre los sectores biogeográficos.
The Dialogical Potential of Facebook: The Case of Fashion Brands
Authors: Beltrá Marián Navarro , Medina Irene Garcia , Correia Pedro Pereira
Published: March 2020

The main goal of this study is to examine the communication that fashion brands make through Facebook. It is intended to ascertain if the fashion brands use a communication strategy based on dialogue with their followers. In order to reach the objectives indicated above, a content analysis has been carried out (quantitative methodology) of 326 publications made through Facebook by H&M, Zara and Ralph Lauren between January 1st and June 30th of 2017. The main results of this work show that, although Facebook has a wide dialogical potential, fashion brands do not use it to a great extent. Although we consider appropriate to have analyzed only the social network Facebook given its importance, this situation could be considered as the main limitation of the present study, since the fashion brands could, or not, be taking advantage of the dialogical potential of other social networks, such as Twitter or Instagram. It could be considered that this research stands out for studying a series of variables that allows organizations to know if they are using the dialogical potential offered by digital communication.
Secure Cloud-Mediator Architecture for Mobile-Government using RBAC and DUKPT

Published: March 2020

Smart mobile devices and cloud computing are widely used today. While mobile and portable devices have different capabilities, architectures, operating systems, and communication channels than one another, government data are distributed over heterogeneous systems. This paper proposes a 3-tier mediation framework providing single application to manage all governmental services. The framework is based on private cloud computing for adapting the content of Mobile-Government (M-Government) services using Role-Based Access Control (RBAC) and Derive Unique Key Per Transaction (DUKPT). The 3-layers in the framework are: presence, integration, and homogenization. The presence layer is responsible for adapting the content with regard to four contexts: device, personal, location, and connectivity contexts. The integration layer, which is hosted in a private cloud server, is responsible for integrating heterogeneous data sources. The homogenization layer is responsible for converting data into XML format. The flexibility of the mediation and XML provides an adaptive environment to stream data based on the capabilities of the device that sends the query to the system.
Software Development Framework for Real-Time Face Detection and Recognition in Mobile Devices

Published: March 2020

With the rapid use of Android OS in mobile devices and related products, face recognition technology is an essential feature, so that mobile devices have a strong personal identity authentication. In this paper, we propose Android based software development framework for real-time face detection and recognition using OpenCV library, which is applicable in several mobile applications. Initially, the Gaussian smoothing and gray-scale transformation algorithm is applied to preprocess the source image. Then, the Haar-like feature matching method is used to describe the characteristics of the operator and obtain the face characteristic value. Finally, the normalization method is used to match the recognition of face database. To achieve the face recognition in the Android platform, JNI (Java Native Interface) is used to call the local Open CV. The proposed system is tested in real-time in two different brands of smart phones, and results average success rate in both devices for face detection and recognition is 95% and 80% respectively.

Communication between teachers and parents is essential to foster parental involvement in school related activities. The purpose of this study is to evaluate the effectiveness of mobile instant messaging for parent-teacher communication in enhancing two-way communication between parents and teachers. In particular, the research examines the barriers on parental involvement and investigates the relationship between the use of mobile instant messaging for parent-teacher communication, as well as for families of different socio-economic and educational background. In addition, the study also evaluates parents’ attitudes and perceptions towards the use of mobile instant messaging for communication with teachers. The respondents for this study were 251 parents with different background. This study employed a mix-method research design which involved quantitative and qualitative data. The findings revealed that time constraint is the primary reason for parents to be involved in school related activities. The study results also indicated that there is no relationship between family socio-economic background and the use of mobile instant messaging for parent-teacher communication. However, the findings show a significant relationship between parents’ educational background and the use of mobile instant messaging for parents-teacher communication. Moreover, the study also found a receptive attitude among parents towards mobile based communications with teachers and school
