A Review of Hashing based Image Copy Detection Techniques
Authors: Srivastava Mayank , Siddiqui Jamshed , Ali Mohammad Athar 
Published: June 2019

Abstract
Images are considered to be natural carriers of information, and a large number of images are created, exchanged and are made available online. Apart from creating new images, the availability of number of duplicate copies of images is a critical problem. Hashing based image copy detection techniques are a promising alternative to address this problem. In this approach, a hash is constructed by using a set of unique features extracted from the image for identification. This article provides a comprehensive review of the state-of-the-art image hashing techniques. The reviewed techniques are categorized by the mechanism used and compared across a set of functional & performance parameters. The article finally highlights the current issues faced by such systems and possible future directions to motivate further research work.

Abstract
Berry skin colour is a crucial determinant of red/black grape berry quality. We investigated the effects of combination treatments with amino acids and a low concentration of ABA on anthocyanin accumulation in grapes. Among the amino acids tested, isoleucine and phenylalanine resulted in high anthocyanin contents in grape cell cultures. The combination treatments with isoleucine or phenylalanine, and a low concentration of ABA enhanced anthocyanin accumulation in grape cells and detached grape berries. The combination treatment with isoleucine, but not with phenylalanine, and ABA upregulated MybA1 expression. Field-grown grapevines received combination treatments with isoleucine or phenylalanine, and ABA in two growing seasons. In the 2015 growing season, the combination treatments with isoleucine or phenylalanine, and a low concentration of ABA accelerated anthocyanin accumulation in grape berry skins of field-grown grapevines on days 10 and 31 post treatment. The effects on anthocyanin accumulation became negligible at harvest. The effect of the combination treatment with phenylalanine and a low concentration of ABA on anthocyanin accumulation was masked in the 2017 growing season due to the unexpected stimulation of anthocyanin accumulation by the low concentration of ABA, although the combination treatment accelerated anthocyanin accumulation on days 3 and 10 post treatment. Taken together, the results suggested that exogenous isoleucine and phenylalanine interacted with ABA-mediated anthocyanin accumulation in grape berry skins of field-grown grapevines when the activity of ABA used to treat the grapevines was inadequate.
Use of biocides for controlling viral diseases that attack common bean and cucumber plants
Authors: Helal Ismail Mohamed 
Published: June 2019

Abstract
This study aimed at investigating the antiviral activities of biocides made of formulated essential oils. These were derived from five plant species: fennel, oregano, peppermint, thyme and ginger. The potencies of these preparations were tested against local infection with the Tobacco necrosis virus (TNV) on common bean (Phaseolus vulgaris L.) and against systemic infection with the Cucumber mosaic virus (CMV) on cucumber (Cucumis sativus L.). After the determination of the most effective concentration, the formulated biocides were tested in protective and curative manners (before and after virus inoculation) against the growth of plants. The obtained results showed that the peppermint-derived biocide had the greatest effect on reducing the infectivity of the TNV virus (100% growth inhibition at 4000 ppm), whereas the biocide from thyme was the most effective against the infectivity of the CMV virus, as it induced a complete growth inhibition at 3000 ppm. The results of the protective and curative experiments revealed that the formulated biocides exerted high protection and curative effects against the two viruses. The observations revealed that the biocides were able to enhance plant defences against viral infection, as indicated by the increased levels of total chlorophyll, protein and phenols. Moreover, the levels of the oxidative stress markers including peroxidase (POD), polyphenol oxidase (PPO) and phenylalanine ammonia lyase (PAL) were improved compared to the control settings. In conclusion, the formulated biocides progressively present a favourable alternative to chemically synthesized pesticides in crop protection.
Salicylic acid and jasmonic acid can suppress green and blue moulds of citrus fruit and induce the activity of polyphenol oxidase and peroxidase

Published: June 2019

Abstract
The ability of salicylic acid and jasmonic acid to suppress post-harvest infection with green mould Penicillium digitatum and blue mould P. italicum on three citrus species Citrus reticulata ‘Kinnow’, C. limon ‘Meyer Lemon’, and C. limetta ‘Mosambi’ was evaluated in a dose-response study. Salicylic acid (SA) and jasmonic acid (JA) were applied to the fruits as a post-harvest dip treatment followed by wound inoculation with the pathogens. Both resistance inducers caused a significantly lower disease severity compared with the infected but non-treated control, whereas disease incidence was not significantly lower than in the control. The efficacy of both SA and JA in reducing disease severity was concentration-dependent; the use of higher concentrations resulted in a greater degree of suppression. All the Citrus species tested in this study showed different responses in terms of disease development. C. limon ‘Meyer Lemon’ showed the highest disease development, and C. limetta ‘Mosambi’ the lowest. To get an insight into the mechanisms underlying the increase in resistance, the activity of defence-related enzymes – peroxidase (POD) and polyphenol oxidase (PPO) – was recorded in SA- and JA-treated fruit peelings. The activity of both enzymes was directly proportional to the concentration of the SA and JA applications. The highest activity of PPO and POD was observed in C. reticulata ‘Kinnow’ and the lowest in C. limon ‘Meyer Lemon’ fruits. This study is the first to document an increase in the activity of PPO and POD in SA- and JA-treated Citrus species in the presence of blue mould and green mould pathogens.
Influenza and sudden unexpected death: the possible role of peptide cross-reactivity
Authors: Kanduc Darja 
Published: June 2019

AbstractThis study investigates the hypothesis that cross-reactions may occur between human cardiac proteins and influenza antigens, thus possibly representing the molecular mechanism underlying influenzaassociated sudden unexpected death (SUD). Using titin protein as a research model, data were obtained on (1) the occurrence of the titin octapeptide AELLVLLE or its mimic AELLVALE in influenza A virus hemagglutinin (HA) sequences; (2) the immunological potential of AELLVLLE and its mimic AELLVALE; (3) the possible role of the flanking amino acid aa) context of the two octapeptide determinants in eliciting cross-reactivity between the human cardiac titin protein and HA antigens.
Remarks on Geo-Logarithmic Price Indices
Authors: Białek Jacek 
Published: June 2019

Abstract
As is known, all geo-logarithmic indices enjoy the axiomatic properties of being proportional, commensurable and homogeneous, together with their cofactors (Martini 1992a). Geologarithmic price indices satisfying the axioms of monotonicity, basis reversibility and factor reversibility have been investigated by Marco Fattore (2010), who has shown that the superlative Fisher price index does not belong to this family of indices. In this article, we discuss geo-logarithmic price indices with reference to the Laspeyres-Paasche bounding test and we propose a modification of the considered index family that satisfies this test. We also modify the structure of geo-logarithmic indices by using an additional parameter and, following the economic approach, we list superlative price index formulas that are members of the considered price index family. We obtain a special subfamily that approximates superlative price indices and includes the Fisher, Walsh and Sato-Vartia price indices.
Decomposing Multilateral Price Indexes into the Contributions of Individual Commodities
Authors: Webster Michael , Tarnow-Mordi Rory C. 
Published: June 2019

Abstract
This article describes methods for decomposing price indexes into contributions from individual commodities, to help understand the influence of each commodity on aggregate price index movements.
Previous authors have addressed the decomposition of bilateral price indexes, which aggregate changes in commodity prices from one time period to another. Our focus is the decomposition of multilateral price indexes, which aggregate commodity prices across more than two time periods or countries at once. Multilateral indexes have historically been used for spatial comparisons, and have recently received attention from statistical agencies looking to produce temporal price indexes from large and high frequency price data sets, such as scanner data. Methods for decomposing these indexes are of practical relevance.
We present decompositions of three multilateral price indexes. We also review methods proposed by other researchers for extending multilateral indexes without revising previously published index levels, and show how to decompose the extended indexes they produce. Finally, we use a data set of seasonal prices and quantities to illustrate how these decomposition methods can be used to understand the influence of individual commodities on multilateral price index movements, and to shed light on the relationships between various multilateral and extension methods.
Genetic sequence stratigraphy on the basis of ichnology for the Middle Jurassic basin margin succession of Chorar Island (eastern Kachchh Basin, western India)
Authors: Darngawn Jehova L. , Patel Satish J. , Joseph Jaquilin K. , Shitole Apuva D. 
Published: June 2019

Abstract
Synrift basin margin successions are greatly influenced by eustatic sea level changes, tectonics and accommodation space filled in by sediments. The Middle Jurassic (Bajocian–Callovian) of Chorar Island (western India) comprises a ~109-m-thick synrift basin margin succession of clastic, non-clastic and mixed siliciclastic-carbonate rocks which are here analysed and categorised into nine lithofacies. The succession is bioturbated to varying intensities; 16 identified ichnogenera can be assigned to environmentally related groups of five trace fossil assemblages, which include Gyrochorte, Hillichnus, Rhizocorallium, Skolithos and Thalassinoides. These ichnoassemblages document the Skolithos and Cruziana Ichnofacies which marks a change in energy conditions, sedimentation dispersal patterns and bathymetry in a shallow-marine environment. The Bajocian–Callovian succession is further analysed on the basis of sedimentological and ichnological data that show two genetic sequences consisting of Transgressive Systems Tract and Highstand Systems Tract bounded by Maximum Flooding Surface. The synrift basin margin succession of the Middle Jurassic of Chorar Island shows cyclicity in deposition; the Bajocian–Bathonian succession represents progradational to retrogradational coastlines, while the Callovian succession documents an aggrading progradational coastline.
Long-term shoreline shifts on continental blocks during the Bajocian: an updated interpretation based on synthetic stratigraphical and palaeogeographical developments on regional scales
Authors: Ruban Dmitry A. , Sallam Emad S. 
Published: June 2019

Abstract
Available reconstructions of Jurassic global sea level changes differ and are in need of an update. New stratigraphical charts and palaeogeographical developments for a number of large continental blocks or their portions of these (e.g., Germany, India, northeast Africa, northwest Australia, the Russian Platform and western Siberia) reveal regional long-term shoreline shifts (i.e., transgressions and regressions) during the Bajocian Stage (168.3–170.3 Ma). A comparison of these allows to document only a single coherent feature, namely the earliest Bajocian transgression, in the majority of the continental blocks considered. Undoubtedly, this event was triggered by a eustatic rise. However, long-term shoreline shifts were either weak to absent or differed between the blocks during almost the entire Bajocian, thus providing evidence of the apparent stability of global sea level and the importance of regional tectonic activity as a control mechanism on particular transgressions and regressions. Interestingly, it appears that the earliest Bajocian eustatic rise was a constituent of a long-term eustatic pattern; the nature of this event has yet to be fully understood. Generally, the findings presented here are in better agreement with Anthony Hallam’s view of Jurassic eustasy and question some other global sea level reconstructions.
Pay Dissatisfaction among Municipal Employees: Empirical Evidence from Russia’s Stavropol Region
Authors: Jäkel Tim 
Published: June 2019

Abstract
Dissatisfied public employees put at risk the quality of service delivery. Th is study investigates pay dissatisfaction among a sample (N=501) of municipal employees in Russia’s Stavropol region. We find that pay dissatisfaction results from negative perceptions of public employment compensation, low levels of risk aversion, unethical professional attitudes, and more than 4 years of working experience. Our findings suggest that municipal employees are sensitive to multiple wage gaps within the public sector, and that upward pay comparisons are a relevant predictor of dissatisfaction with pay. We conclude that widespread pay dissatisfaction poses a serious threat to the implementation of federal programs and sustainable rural development in Russia.
The Hungarian Experiences with Handling Irregularities in the Use of EU Funds
Authors: Nyikos Györgyi , Kondor Zsuzsanna 
Published: June 2019

Abstract
Using European Union funds involves a complex process; Member States must adhere to wide-ranging EU and domestic legislation, non-compliance can lead to irregularities. Besides accordance with the letter of the law, also the general EU budgetary principles, in particular sound financial management, must be given full consideration. The paper presents Hungary’s evolving approach to handling irregularities and her experience in creating the corresponding legal and institutional framework. The research also assesses how the perspective of the European Commission, in particular of its auditors, has contributed to legal uncertainties.
In the draft legislation for the 2021 – 2027 budgetary period, the European Commission proposes a new requirement, namely the rule of law conditionality.3 Its clarity and objectivity, however, are still being widely discussed. Additionally, cohesion policy conditionalities have always contained an obligation for the proper functioning of the institutions – including the courts. Nonetheless, the European Commission has not previously examined the performance of the courts in relation to proceeding irregularity and recovery disputes. The presented Hungarian case study not only explains the particular challenges that call for revisiting the appeal system in Hungary; it warns of the general difficulties Member States may face when embedding the irregularity and recovery management functions into their national legislation, whereas the paper also gives notice to the long-awaited analysis of the root problems invoking irregularities.

Authors: Šagát Vladimír , Plaček Michal , Kolman Petr 
Published: June 2019

Abstract
This article deals with the analysis of the impact of fiscal rules on financial management within the higher self-governing units of the Slovak Republic. For this analysis, unique data from 2002 – 2016 has been used. The quantitative analysis is complemented by a questionnaire survey and a structured interview of respondents who are responsible for controlling the financial management of higher territorial units. This analysis has shown the positive effect of fiscal rules on regional economics, but also revealed shortcomings that prevent the full use of fiscal rules in Slovakia. Th is is primarily due to incomplete and formal implementation, the interests of local elites, and a lack of coordination of activities with the central government.
Autonomy, Collaboration and Competition: The Impact of Education Management Reforms which Aim to Increase School Autonomy on Relations between Schools

Published: June 2019

Abstract
In recent decades, the neoliberal education policy has been implemented in many countries, by reducing the state’s role in education management. Lithuania is one of the countries which after the restoration of Independence in 1991 and collapse of the Soviet Union has decentralized its education management system by giving more autonomy to schools and local authorities. Education-management reforms, which have already been implemented or are currently being implemented in response to social, economic and political changes in the country, have an impact on relationships between schools. Purpose: This article reports the findings of a study which reviewed education management reforms aimed at increasing school autonomy and their impact on inter-school collaboration and competition. Research Method: This study employs a qualitative research design with semi-structured interviews. Twenty-four elementary and secondary school principals from different regions of Lithuania were interviewed. Findings: The results reveal that a significant influence on relations between schools comes from government decisions which relate to school autonomy, school choice, allocation of funds, school ranking, and the like. Implications: This study generates discussions on the impact of the education management reforms which aim to enhance school autonomy on inter-school relationships. In order to answer that question, a theoretical model of research was developed, including the theoretical basis of school autonomy, collaboration and competition, as well as the characteristics of Lithuanian education governance.
Effectiveness Measurement Using DEA & BSC Methods in Public Health Services

Published: June 2019

Abstract
It is well-known that health-care systems all over the world try to improve efficiency and effectiveness due to high pressure to pursue rational performance. Many of the health-care reforms in different countries are conducted with the objectives to rationalise costs, to make health services more available, and to increase, or at least not to reduce, the quality of health services. Adequate efficient metrics used in assessing health-care services are critical for the quality of decision-making. The subject of this research is efficiency measurement in the institutes of public health in Croatia oriented to preventive activities, i.e. monitoring, analysis, and evaluation of the health of the population. Diversity of the programmes and temporal variability are the characteristics of public health services, and it is therefore harder to measure the effects in the long run. This research aims to analyse and propose a new approach to the measurement system using two methods: the Data Envelopment Analysis (DEA) and the Balanced Score Card (BSC), combined into the DEABSC integrative model, which can be an efficient method for the decision-making process. The starting point of this research is the analysis of the measurement system in public-health services in Croatia. The results confirm a weak and inadequate efficiency measurement system and very low effectiveness measurement. To enhance the efficiency measurement, we have developed the conceptual integrative DEABSC model which has been tested at the Teaching Institute of Public Health – the Department of Health Ecology. Using DEA for 2017, we have identified relatively efficient units that helped establish future goals set in the BSC strategic map. The combination of DEA and BSC allows identifying options for improving the effectiveness of public-health service programmes. The study confirms that it is possible to determine the relative efficiency of different DMUs within the Department of Health Ecology and use best practice for each perspective in the BSC Cause & Effect conceptual model. This paper also provides recommendations for an easier establishment of performance measurement in order to achieve the mission of public health institutions, but also indicates some limitations in the application of the methods.

Published: June 2019

Abstract
This paper describes a method of retrieving stereoscopic medical images from the database that consists of feature extraction, similarity measure, and re-ranking of retrieved images. This method retrieves similar images of the query image from the database and re-ranks them according to the disparity map. The performance is evaluated using the metrics namely average retrieval precision (APR) and average retrieval rate (ARR). According to the performance outcomes, the multi-feature based image retrieval using Mahalanobis distance measure has produced better result compared to other distance measures namely Euclidean, Minkowski, the sum of absolute difference (SAD) and the sum of squared absolute difference (SSAD). Therefore, the stereo image retrieval systems presented has high potential in biomedical image storage and retrieval systems.
