Language Learning in the Third Age
Authors: Bosisio Nicole 
Published: December 2019

Abstract
This paper discusses the importance of foreign language learning as a means of maintaining healthy cognitive, psychological and social functioning in elderly people. It argues that a complex cognitive activity involving multiple skills and stimulating extensive neural networks can greatly contribute to contrast the inception of neurodegenerative disorders such as Alzheimer’s and other types of dementia. Because of age-related physical and mental limitations, and because old learners find it hard to abandon tried-and-tested methodologies and attitudes, it is, however, crucial that teachers and educators try to meet the older adult’s needs by customising teaching procedures and learning environment to their requirements and expectations. Rather than introducing a great amount of new information and learning techniques, it may be much more fruitful to encourage the older adult to retrieve and rely on previously acquired knowledge and consolidated learning strategies. The adoption of computer-assisted language learning, however, may be helpful and motivating for older learners, provided technological demands are kept to a minimum.
ICT, Senior universities and digital security
Authors: Jacob Luis , Pocinho Ricardo 
Published: December 2019

Abstract
The Senior Universities (US) in Portugal are socio-educational organisations, of non-formal education, officially recognised by the Resolution of the Council of Ministers nº 76/2016. According to the National Network of Senior Universities (RUTIS), there were 330 US in Portugal with a total of 45,000 senior students in 2019.
Since the beginning of the US, computer education has been one of the most sought after topics for seniors. In 2018, 62% of students attended a course related to Information and Communication Technologies (ICT). This teaching has gone through three phases in the US that we will present.
In the study carried out by the author to 1,016 senior students from all over the country, it was possible to conclude that the frequency of the US contributed a great deal to diminish digital illiteracy and that it is in the older and less literate public that these contributors are more visible. It was also possible to realise that most US students have smartphones and laptops and understand the evolution that the use of computers has had in the US.
Coping and Resilience in Life-Long Learning and Ageing: new challenges
Authors: Spulber Diana 
Published: December 2019

Abstract
The society is becoming increasingly cosmopolitan as a consequence of driving wave of globalisation. Today we are living in a society with rapid dynamic changes and technologic it can be called the IT era. The one most used paradigm is “knowledge society”. The academic world uses this term for analysing the socio-economic transformation toward so-called post-industrial society. It is also used by politics world when the discourses are about the normative vision that the state, governs should aspire to fulfil or when the economic situation and the link with Universities take into consideration. Often the knowledge society is used in relationship with the economy of innovation or information society or technologic society metaphors that are used for to indicate that the labour market is in rapid change and technological competences are required.
The demographic situation is also in rapid evolution: according to UNFPA data in 2019 we are around 7,715 million habitants with 26% of the population aged 0-14, 65% of people aged 15-65 and 9% of people aged more than 65 years. The demographic trends are to have more aged people and less young people. This trend is a new and powerful challenge for society. If we consider that adult percentage of the population is the biggest one and that LLL is seen as a concept that complete the gaps of the formal learning, we can confirm that LLL is a new reply to dynamic exchanges in the society and in the globalised economy.
The article purpose is to analyse the different concepts of LLL and its link with ageing. The main focus will be on how LLL can improve the quality of ageing. The used methodology is a review of relevant intervention studies and Political Documents for examining the effectiveness of interventions and how the elder's literacy can be a value for society.

Summary

Introduction: The broad spectrum of pharmacological properties of linden inflorescence extracts results from polarity and the level of hydrophilic-lipophilic balance of solvents (medium) used to separate compatible phytochemical structures with the expected pharmacotherapeutic profile.

Objective: The use of the general Hildebrand-Scatchard-Fedors theory of solubility to calculate the predicted solubility of classes of phytochemicals contained in linden inflorescences (Tiliae flos) and the indication of those structures which, due to their high solubility in the medium, are responsible for the profile of pharmacological activity.

Material and methods: The Hildebrand, Scatchard equation, supported with computational technique proposed by Fedors, allows calculation of the solubility parameters of the extraction medium. Despite application reservations, it is a fundamental tool for estimating the predictable solubility of phytochemicals in real solution.

Results: The structure of phytochemicals isolated from linden inflorescences (Tiliae flos) owing to the use of solvents of significantly diversified polarity (–dielectric constant – εM) was the basis for calculating the molar evaporation energy – ΣΔEi (cal/mol) and molar volume – ΣΔVi (cm3/mol) by Fedors method, which are fundamental quantities necessary to estimate the solubility parameter – δ1/2 and required solubility level of hydrophilic-lipophilic balance – HLBRequ.

Conclusions: Results of the presented research indicate that basing on the parameters characterizing the structure of phytochemicals and the calculated ideal (–logxi
2) and predicted real (– log x2) solubility, it is possible – using the general Hildebrand-Scatchard-Fedors theory of solubility – to choose selectively the cascade of extraction media in order to distinguish in the plant material chemical and structural individuals of different polarity.

Published: December 2019

Summary
A lot of products from food category specified in Regulation No. 609/2013 may contain herbal substances or their preparations. Definitions of food for infants and toddlers, food for special medical purposes, and total diet replacement for weight control are now clearly regulated by UE food legislation. The concept and definition of foodstuffs for particular nutritional published in Directive 2009/39/EC of the European Parliament and Council of 6 May 2009 do not apply. On 22 February 2019, Commission Delegated Regulation (EU) 2016/128 complementary to Regulation (EU) No. 609/2013, regarding specific compositional and information requirements for food of special medical purposes was applied. Novel foods and novel food ingredients are foods which have not been used for human consumption in UE to a significant degree before 15 May 1997.
A Strong and Efficient Baseline for Vehicle Re-Identification Using Deep Triplet Embedding

Published: December 2019

Abstract
In this paper we tackle the problem of vehicle re-identification in a camera network utilizing triplet embeddings. Re-identification is the problem of matching appearances of objects across different cameras. With the proliferation of surveillance cameras enabling smart and safer cities, there is an ever-increasing need to re-identify vehicles across cameras. Typical challenges arising in smart city scenarios include variations of viewpoints, illumination and self occlusions. Most successful approaches for re-identification involve (deep) learning an embedding space such that the vehicles of same identities are projected closer to one another, compared to the vehicles representing different identities. Popular loss functions for learning an embedding (space) include contrastive or triplet loss. In this paper we provide an extensive evaluation of triplet loss applied to vehicle re-identification and demonstrate that using the recently proposed sampling approaches for mining informative data points outperform most of the existing state-of-the-art approaches for vehicle re-identification. Compared to most existing state-of-the-art approaches, our approach is simpler and more straightforward for training utilizing only identity-level annotations, along with one of the smallest published embedding dimensions for efficient inference. Furthermore in this work we introduce a formal evaluation of a triplet sampling variant (batch sample) into the re-identification literature. In addition to the conference version [24], this submission adds extensive experiments on new released datasets, cross domain evaluations and ablation studies.
Rough Support Vector Machine for Classification with Interval and Incomplete Data
Authors: Nowicki Robert K. , Grzanek Konrad , Hayashi Yoichi 
Published: December 2019

Abstract
The paper presents the idea of connecting the concepts of the Vapnik’s support vector machine with Pawlak’s rough sets in one classification scheme. The hybrid system will be applied to classifying data in the form of intervals and with missing values [1]. Both situations will be treated as a cause of dividing input space into equivalence classes. Then, the SVM procedure will lead to a classification of input data into rough sets of the desired classes, i.e. to their positive, boundary or negative regions. Such a form of answer is also called a three–way decision. The proposed solution will be tested using several popular benchmarks.
The Significance of Death-Scene Investigation in Determining Cause and Circumstances of Medico-Legal Death
Authors: Crișan Corina 
Published: December 2019

Abstract
The article presents two cases of the Arad Medico-Legal Department illustrating just a part of the role of the forensic pathologist at the death scene but there are sufficient to fully justify the importance of this investigation as no example can comprise the complexity of problems and the particularity of each case, nor a statistic can be made. Both cases were found dead at home and forensically autopsied, but the two of them were distinct in terms of forensic pathologist's request death scene participation. In the first case, the autopsy did not find traumatic lesions, but revealed that the death was due to massive hemoptysis caused by cavernous tuberculosis with subsequent exsanguination, microscopically confirmed. The death was nonviolent. In the second case, the autopsy revealed findings of mechanical asphyxia due to neck compression, both macroscopically and microscopically. The death was violent. In both cases the forensic expert participation is required at the death-scene.
In the first case it allowed the correct interpretation of the traces of blood found on site, and in the second case, an onsite research would have properly helped for restoring the death‟s occurrence.
The scene investigation and autopsy provide, together, the basis for an accurate determination of cause and circumstances of death.
Test of a Hybrid Method of Sampling the LGBT Population: Web Respondent Driven Sampling with Seeds from a Probability Sample
Authors: Michaels Stuart , Pineau Vicki , Reimer Becky , Ganesh Nadarajasundaram , Dennis J. Michael 
Published: December 2019

AbstractThis article presents the results of a pilot feasibility study comparing two alternative recruitment approaches based on Respondent Driven Sampling using initial seeds selected from a US nationally representative panel, AmeriSpeak, to augment the number of lesbian, gay, bisexual, and transgender (LGBT) respondents to a short web survey on smoking, discrimination, and health. In the nomination condition after completing the survey both LGBT and non-LGBT seeds were invited to share the names and email address of up to four LGBT persons they knew. In the recruitment condition, seeds were given four unique PINs and links to the survey to distribute to LGBT persons. Both conditions were successful in producing new LGBT respondents. The recruitment condition was much more productive. LGBT seeds (and their recruits) were much connected to and willing to contact other LGBT people they knew to participate in a survey. Comparisons of characteristics and responses from the initial samples and the LGBT referrals as well as comparisons to LGB samples from a large national survey are presented. Results demonstrate the promise of this hybrid technique for increasing the number of LGBT respondents through referrals from an initial probability based sample.
Asking about Sexual Identity on the National Health Interview Survey: Does Mode Matter?
Authors: Dahlhamer James M. , Galinsky Adena M. , Joestl Sarah S. 
Published: December 2019

AbstractPrivacy, achieved through self-administered modes of interviewing, has long been assumed to be a necessary prerequisite for obtaining unbiased responses to sexual identity questions due to their potentially sensitive nature. This study uses data collected as part of a split-ballot field test embedded in the National Health Interview Survey (NHIS) to examine the association between survey mode (computer-assisted personal interviewing (CAPI) versus audio computer-assisted self-interviewing (ACASI)) and sexual minority identity reporting. Bivariate and multivariate quantitative analyses tested for differences in sexual minority identity reporting and non-response by survey mode, as well as for moderation of such differences by sociodemographic characteristics and interviewing environment. No significant main effects of interview mode on sexual minority identity reporting or nonresponse were found. Two significant mode effects emerged in subgroup analyses of sexual minority status out of 35 comparisons, and one significant mode effect emerged in subgroup analyses of item nonresponse. We conclude that asking the NHIS sexual identity question using CAPI does not result in estimates that differ systematically and meaningfully from those produced using ACASI.

Authors: Barańczuk Katarzyna , Barańczuk Jacek 
Published: December 2019

Abstract
The article presents the ice phenology of Lake Ostrzyckie, which is a water body covering an area of 308 ha located in the central part of the Kashubian Lakeland, northern Poland. The analysis presented in the article is based on data from daily ice phenomena monitoring for the period of 1971–2010. Data including forms of lake ice, as well as the thickness of the ice cover were obtained from the Institute of Meteorology and Water. In order to present relations between the ice phenomena and air temperature the meteorological data from the Gdańsk University Limnological Station in Borucino were used. The article presents changes in the duration time of the ice seasons and changes in the ice cover duration time in relation to winter season (November–April) temperatures. The structure of the ice phenomena duration period observed on Lake Ostrzyckie consists of three different stages of ice cover formation. 94% of this time the lake is covered by permanent ice cover, the freezing period takes about 5%, and the break-up takes only 1% of the ice phenomena duration period. In general the ice phenomena in the lake can occur only in the years when the average air temperature in the winter is lower than 5.0°C, whereas the permanent ice cover is created when the average air temperature of the winter season is lower than 4.8°C. The maximum thickness of the ice cover is usually 23 cm, and the average is 14 cm.
Structural characteristic of vanadium(V) oxide/sulfur composite cathode for magnesium battery applications
Authors: Sheha E. , Kamar E.M. 
Published: December 2019

Abstract
Magnesium batteries are regarded as promising candidates for energy storage devices owing to their high volumetric capacity. The practical application is hindered, however, by strong electrostatic interactions between Mg2+ and the host lattice and due to the formation of a passivation layer between anode and electrolyte. V2O5 is a typical intercalation compound with a layered crystal structure ((0 0 1) interlayer spacing ~ 11.53 Å), which can act as a good host for the reversible insertion and extraction of multivalent cations. Herein, we have presented an investigation of the effects of S injection on the structure, electrochemical performance and Mg2+ diffusion in V2O5 cathode materials for Mg-ion batteries. The V2O5/S composite structure was investigated using X-ray diffraction, field-emission scanning electron microscope and energy dispersive X-ray spectroscopy. The integrated electrode exhibits an improvement in the electrical and electrochemical properties compared to the V2O5 electrode. The as-prepared V2O5/S composite has an initial discharge capacity of 310 mAh g−1 compared to 160 mAh g−1 for the V2O5 electrode. The V2O5/S composite is a promising cathode material for magnesium-ion battery applications.

Published: December 2019

Abstract
This study examines public organisations planning big data-driven transformations in their service provision. Without radical structural change or managerial system changes, leaders face dilemmas: simply bolting on big data makes little difference. This study is based on a qualitative empirical case study using data collected from the cities of Helsinki and Tampere in Finland. The three core dilemma pairs detected and connected to the big data-related organisational changes are: (1) repetitive continuity vs. visionary change, (2) risk-taking vs. security-seeking and (3) technology-based development vs. human-based development. This study suggests that organisational readiness involves not only capabilities; instead, readiness involves absorbing knowledge, making decisions, handling ambiguities, managing dilemmas. Thus, big data-related transformations in public organisations require embracing the world of dilemmas, since selected and cancelled experiments may each have valuable outcomes. The capability to act on intentions is a prerequisite for readiness; however, a preparedness to detect and address dilemmas is central to big data-related transformations. Thus, the ability to make dilemma decisions is a more complicated characteristic of readiness. In conclusion, our data analysis suggests that traditional public organisational and chance management approaches produce unsolved dilemmas in big data-related organisational changes.
Welfare Co-Production: Hungarian and Slovak Reality

Published: December 2019

Abstract
For more than 30 years the delivery of local public services has been undergoing change, from a style of delivery dominated by the public sector to a more efficient, more effective mixed system, characterised by variations in ownership and sources of financing. Concepts such as public-private-civil sector mix, partnerships, co-operation, and co-creation have emerged as ways of organising public-services production and delivery. Our case deals with co-production via the involvement of the third sector in welfare services. The goal of this paper is to map the real relations between public bodies and the non-governmental sector in the co-production of welfare services in two newer EU member countries – Hungary and Slovakia. The information obtained suggests that the examples of good practice exist, but at a global level the quality of partnership between the government and the non-governmental sector is problematic. The study also highlights important drivers and barriers determining the quality of collaboration and the results of projects – limited resources (mostly financial) to implement collaborative welfare innovations on both sides seem to be the core barrier.
Arrangements for the Transfer of Social-Services Delivery to Non-Governmental Providers (Regional Practices, Russia)
Authors: Zabolotnaya Galina , Larionov Andrey 
Published: December 2019

Abstract
The study focuses on the Russian practice of institutionalizing non-governmental social-service providers. The paper discusses the arrangements for the transfer of governmental social services under the terms of budget financing to commercial and non-profit organizations. The authors proceed from the fact that although there are uniform institutional conditions for the formation of the non-governmental sector in the field of social services, established by the federal center, most of the rules and procedures which determine the implementation of this process are defined on the level of the constituent subjects of the Russian Federation. The paper explores the practices of three regions: Perm, the Republic of Bashkortostan and Khanty-Mansiysk Autonomous Okrug-Ugra. These regions are recognized as the leaders in the process of diversification of social services. The analysis made it possible to identify the general and the particular in the regional processes of the transfer of social services to the non-governmental sector.

Published: December 2019

Abstract
A model of REM-2-type chamber was modeled with MCNPX code to study the dose-response to monoenergetic neutrons in wide energy range from thermal to 20 MeV for various compositions of gas in the chamber. The energy dependence of the total dose absorbed in the filling gas was compared with the energy dependence of ambient absorbed dose D*(10) and with experimental data. The results of the studies will be useful for designing new, improved generation of recombination chambers.
