Published: December 2019

Abstract
The present work examines the influence of the leaching conditions on the release of various chemical elements from a cementitious material obtained by solidification of an industrial waste rejection of Algeria. Toxicity Characteristic Leaching Procedure (TCLP), X-ray diffraction (XRD) and Scanning electron microscopy coupled with energy dispersive X-ray microanalysis SEM-EDX analyses were employed to characterize the waste and the stabilized/solidified materials. Than several formulations were prepared with different percent of waste ranging from 0 % to 30 %. To evaluate the influence of leaching conditions on the release of chemical ions (Zn2+, Pb2+, Cl-, Mg2+, Ca2+, Na+, K+ and SO42−) contained in the stabilized and solidified materials, the Acid Neutralization Capacity (ANC), the Pore Water (PW) and Monolith Leaching Tests (MLT) have been carried out. The leaching tests (ANC, PW and MLT) have shown a low metal leachability. However, the lowest released amount was observed for the MLT.

Authors: Smekalova Tamara N. , Lebedeva Natalia V. , Novikova Lyubov Yu. 
Published: December 2019

Abstract
The article is dedicated to morphological analysis of the Jerusalem artichoke genetic resources collected at the N. I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR). The crop has a wide range of various usages, such as: food and feed, and medicinal, melliferous, and ornamental products. In this study, morphological characteristics of vegetative and generative plant organs (stems, leaves, tubers and inflorescences) from the VIR collections in the Maikop Experiment Station of VIR (Russian Caucasus, Republic of Adygea) and in Gatchina District, Leningrad Province, Russia were analysed. The widest range of variability was observed in accessions from Western Europe. Accessions from United States, Japan and Australia were the most unique in their set of traits, which may indicate specific paths of their evolution in these isolated territories. Accessions with unique combinations of studied traits were determined. Some traits characterizing leaf, inflorescence and tuber proved to be valuable for taxonomic and geographic analyses.
Content of Phenolic Compounds and Antioxidant Activity in Fresh Apple, Pomace and Pomace Water Extract — Effect of Cultivar
Authors: Krasnova Inta , Segliņa Dalija 
Published: December 2019

Abstract
The study aimed to evaluate the chemical composition (total phenol, flavonoid, and tannin content and the antioxidant activity) of 11 apple (Malus domestica) cultivars in fresh apples and their processing by-products — apple pomace and its water extract. In addition, the proportion of chemical compounds and antioxidant activity in fresh apples and pomace transferred to the resulting water extract was calculated. Three different season’s cultivars (autumn–winter, winter and late winter) were selected in the research, and significant differences between chemical parameters within groups were found. Cultivars ‘Zarja Alatau’, ‘Belorusskoje Malinovoje’, ‘Sinap Orlovskij’ and ‘Antej’ are characterised by a higher content of determined compounds in fresh apples, pomace and po-mace water extract. The results showed that the water extract in relation to fresh apples and apple pomace still contains an appropriate amount of total phenols, flavonoids and tannins in the range 2.5–9.6%. These results indicated that apple pomace water extracts could be recommended for use in food as well as in the pharmaceutical industry.
Limit Theorems for Bivariate Generalised Order Statistics in Stationary Gaussian Sequences with Random Sample Sizes
Authors: Essawe Fatma Hashem , Elgawad Mohamed Abd , Barakat Haroon Mohamed , Zhao Hui 
Published: December 2019

Abstract
In this paper, we study the limit distribution functions of the (lower-lower), (upper-upper) and (lower-upper) extreme and central-central m-generalised order statistics (m–GOS) of stationary Gaussian sequences under an equi-correlated set up, when the random sample size is assumed to converge weakly and independent of the basic variables. Moreover, sufficient conditions for a weak convergence of generalised quasi-range with random indices are obtained.
The concept of ‘rural’ as a psychosocial process: From concept attainment to concept unlearning
Authors: Dymitrow Mirek 
Published: December 2019

AbstractRealising that human geography has been defined less by its canonical works but rather by its canonical concepts, the current status of the concept ‘rural’ puts a question mark over progress in human geography in terms of how well we have been able to adapt knowledge to reciprocate with societal change at large. As one of the oldest geographical concepts still in widespread use, ‘rural’ stands in stark contrast to the immense changes encountered by the society during the last century, let alone decades. And while this problem has been approached both empirically and philosophically, not enough stress has been put on the cognitive and sociological processes that have governed the attainment and retention of ‘rural’ in science, and beyond. In this vein, the aim of this paper is to provide a structured argument for facilitating a view of ‘rural’ less as a geographical space and more as a concept purportedly thought to define such space by way of inculcation.
Does the process of shrinking concern also small towns? lessons from Poland
Authors: Bartosiewicz Bartosz , Kwiatek-Sołtys Agnieszka , Kurek Sławomir 
Published: December 2019

Abstract
The approach to the issue of shrinking cities is undergoing constant changes. Originally, this process was referred primarily to the progressing depopulation connected with a deteriorating economic situation. Presently, works on shrinking cities mainly focus on the challenges posed by the problem rather than the delimitation questions. Do the shrinking also apply to the situation of small towns, and if so, to what extent may small towns shrink? Being conscious of the multidimensional nature of the topic discussed, the authors took measures aimed at singling out a group of shrinking towns from the whole set of small towns in Poland. The identification of depopulating centres consisted in pointing to those shrinking both in terms of their demography and economy. This type of research gives rise to all types of methodological problems such as which tools should be used to measure town shrinking or which data should be selected for the research, an issue particularly important for small towns where the range of indicators available is rather limited. What conclusions may be drawn from the conducted analysis? Do small towns in Poland shrink? On the basis of the conducted research the answer is no. With regard to demography, the process of shrinking concerns only 30 towns (4.5%). And this group includes only four which additionally shrink in economic terms.
The role of a positive spirit in the attractiveness, sociability and success of a public place
Authors: Rahmani Lyes , Messaoudene Maha 
Published: December 2019

Abstract
The objective of this article is to highlight the role of the spirit as an intangible component in the attractiveness, conviviality and success of public places. The comparative study, which covers two public places having the same typo-morphology and sharing the same geographical and sociocultural context, aims to measure the spirits of these two places. The study is based on a theoretical conceptualisation and quantitative analysis of data collected using a measurement tool having satisfactory psychometric qualities. The two main statistical techniques employed are the relative importance index (RII) and the T-test. The results of the study show that the valence
Kurt Lewin was one of the first to use the word ‘valence’. This is in a way synonymous with the value of psychic force with a positive or negative polarity and a degree of high, low or neutral intensity (Rainio 2009).
of the spirit affects the attractiveness, the conviviality and the success of public places.
From policy to misery? the state agricultural farms vs. ‘the rural’
Authors: Biegańska Jadwiga , Dymitrow Mirek , Grzelak-Kostulska Elżbieta , Środa-Murawska Stefania 
Published: December 2019

Abstract1989 was a turning point in the socio-economic development in the former Eastern bloc, initiating a systemic transformation that affected the society at large. It also contributed to the crystallisation of certain cultural landscapes, hitherto largely illegible due to the inhibition of spatial processes encountered during socialism. In Poland, after a quarter-century of a free market economy, the focus on social problems began to expand to the spatial realm as well. It became apparent that the progressive social polarisation that followed was most prominent in environments striated by a particular landscape type – the former State Agricultural Farm (PGR). Considering PGRs as ‘the epitome of rurality’ subject to ideas informing about the direction of contemporary ‘rural development’ prompts a different way of looking at the problem. In this paper, we investigate the concept of rurality in the discursive tenor of implemented policy and contrast it with contextualised empirical examples. Our findings suggest that an efficient policy should be confronted with the expectations of residents at the local level, and introducing top-down actions usually ends in failure as in the case of post-PGR estates.
The dynamics of landscape pattern changes in mining areas: The case study of the Adamów-Koźmin Lignite Basin
Authors: Fagiewicz Katarzyna , Łowicki Damian 
Published: December 2019

AbstractMining belongs to the types of human activity that have a significant impact on the environment, and especially on the landscape. The main objective of this study is a quantitative diagnosis of the dynamics of land use changes and landscape pattern modification in areas shaped under the influence of processes related to the open pit exploitation of lignite. The study was carried out in the Adamów-Koźmin Lignite Basin, which is a model example of an area affected by strong anthropogenic pressure. An assessment of changes was carried out using a set of maps depicting land use in the period preceding the exploitation of lignite (the year 1940) and after over 60 years of the mining activity in this area (as of 2011). The source materials for mapping for the first period were archival maps and for the second period, an orthophotomap. The heads-up digitising method was used to determine 7 types of land-cover classes according to the definitions of Corine Land Cover. Ten landscape metrics for five categories of landscape features (surface, shape, neighbourhood, edge, spatial distribution and diversity) were used in the landscape pattern analysis. The results do not confirm the hypothesis of a significant landscape simplification after reclamation. The shape of patches in the landscape was more complex and the number of land-use types was higher, which combined with their spatial arrangement, caused the landscape pattern to be more diversified in the year 2011.
Design and implementation of a new mobile video analysis laboratory at the University of Salerno
Authors: Todino Michele Domenico , Sibilio Maurizio 
Published: December 2019

Abstract
Nowadays, in many Italian and European universities, teachers’ training includes one or more examinations related to new didactic methodologies and practices. The topic of this paper is how it is possible to realize a new video analysis laboratory as a didactic and research “tool” for teachers’ training at the University of Salerno that can support teaching–learning process for new teachers. The main idea of this project is to design and implement a mobile video analysis laboratory for video recording real or simulated didactic activities. In addition, the concept that drives this research is to develop a “plug-and-play” laboratory that can be installed everywhere in less than 15 minutes by everybody. This laboratory is already designed and tested and is composed of five cameras, a control room software and an open source video analysis software.
Fostering oral presentation skills by the timing of feedback: an exploratory study in virtual reality
Authors: Belboukhaddaoui Ilham , van Ginkel Stan 
Published: December 2019

Abstract
Although scholars emphasised the essence of feedback delivered on virtual reality-based tasks, it remains unclear whether the acquisition of students’ oral presentation skills can be enhanced by the timing of feedback. An exploratory study, recently conducted in a Dutch university, explores the potential differential impact of immediate versus delayed feedback within a virtual reality-based task, in which students present to a virtual audience and receive feedback generated by the computer on presentation behaviour. By making use of an experimental study design, the potential effects of immediate feedback are compared with a control condition of a virtual reality-based presentation task with delayed feedback directly provided after the presentation. Performance assessments, including validated rubrics for oral presentation skills, were used for data collection. The results demonstrated no differences between the impact of immediate and delayed feedback on students’ presentation performance. However, significant differences in performance were traceable for students from differing study domains. As such, students following a technical study showed lower presentation scores in comparison to students from non-technical higher education curricula. More studies are needed to investigate comprehensive learning environments on students’ presentation skills in virtual reality, since combining different forms of feedback could foster students’ learning outcomes.
Digital manipulation versus real one: learning and motivation in a case study on Storytelling
Authors: Tavernise Assunta , Bertacchini Francesca , Pantano Pietro , Bilotta Eleonora 
Published: December 2019

Abstract
In this work, a Storytelling FabLab has been designed for the realization of virtual performances on a Shakesperian play in an elementary school. In this FabLab, many elements have been digitally manipulated: text, audio files, virtual actors on a 3D stage, and 3D Greek masks. Learning of contents and motivation have been assessed and compared to those of a traditional class working on the construction of real masks as artefacts. Regarding learning effectiveness, data show that there is no great difference between the score gained by the experimental group and the control one; however, results emphasize a high intrinsic motivation for both experimental and control groups. Moreover, qualitative results of both groups highlight the positive feeling of doing things reflecting user’s own interest: pupils want to invent their own stories and realize them (physically or digitally).
Preservice teacher disengagement with computer-based learning environments

Published: December 2019

Abstract
Investigating disengagement is a continuing concern within computer-based learning environments. Drawing upon several strands of research into preservice teacher learning with network-based tutors, this paper outlines an object orientation to conceptualize a type of disengaged behaviour referred to as carelessness. We further differentiate this construct in terms of carelessness towards one’s own learning as opposed to other’s learning. In support of our claims, we review research into carelessness in the context of nBrowser, an intelligent web browser designed to support preservice teachers learn about the pedagogical affordances of novel technologies while designing lesson plans. The key aspects of this research can be listed as follows: (1) a knowledge engineering approach to implement a set of production rules within the learning environment to detect instances of carelessness and intervene; (2) a data-driven approach to infer learner behaviours in their absence due to carelessness; and (3) a model-driven approach to improve the functioning of the learning environment despite instances of carelessness. We discuss the limitations of these different approaches and draw implications for future research into preservice teacher disengagement with computer-based learning environments.
Unpacking the Potential of 360degree Video to Support Pre-Service Teacher Development
Authors: Balzaretti Nicoletta , Ciani Andrea , Cutting Chelsea , O’Keeffe Lisa , White Bruce 
Published: December 2019

Abstract
Video has become a useful tool in Initial Teacher Education for self-evaluation and reflection by pre-service teachers (PSTs). The availability of 360degree video cameras and web-based applications, to review and annotate 360degree videos, allows PSTs greater flexibility to view and review their practice from a variety of perspectives. This study explores PSTs’ use of 360degree video for reflection on their teaching practice. 360degree video provides PSTs with the capacity to pan ‘around’ the video, and in doing so has supported PSTs to detach and reflect on their own practice. The findings suggest that the PSTs valued the additional perspectives afforded by the 360degree nature of the video, which had a particular impact on their understanding of their presence, interactions and explanations. Peer video viewing was also found to be a useful tool in supporting PSTs to ‘notice’ additional areas for improvement in their own practice.

Published: December 2019

Abstract
The strategic goal of businesses is to secure a long-term competitive advantage, to differentiate themselves from other businesses and to succeed in the market. Corporate culture is what distinguishes an organization from others and cannot be easily imitated. Culture issues, the need for interaction and understanding are becoming an important part of business behaviour between employees and individual groups.
In the paper we present a part of the results of the research carried out within the frame of VEGA project No. 1/0348/17 „The impact of the coexistence of different generations of employees on the sustainable performance of organisations”. The aim of the project was to explore the potential of positive interaction between individual generations of employees and its use to achieve sustainable performance of organizations in the conditions of multigenerational communities. We focus on corporate culture and selected factors that influence its manifestations and formation. In the research we also found out how important the selected factors are and how individual generational groups of employees in industrial enterprises in Slovakia perceive them. The results of the research confirmed the differences in employee expectations and their fulfilment.

Published: December 2019

Uncertainty with regard to the proper implementation of Article 44 of the Criminal Code is to be discussed. In legal practice, the existence of mental disorder in those who are accused of murder or homicide will be made dependent on the decision of psychiatrist (authorized to conduct forensic psychology or psychiatry). In the case that such mental disorder is determined to be existing during a pre-trial hearing, the court is under no obligation to order cessation of the criminal proceeding. It is noted that in a number of cases the decision to terminate investigation or cease court proceeding falls completely under the Judge discretionary power. The author’s recommendation is that a reformulation of Art. 44 of the Criminal Code is in order.
CONCRETISATION OF THE PRINCIPLE OF SUSTAINABLE FINANCE IN THE BANKING SECTOR LEGISLATION IN INDONESIA: LON FULLER EIGHT DESIDERATA APPROACH
Authors: Dewantara Reka , Agatha Bimarceline 
Published: December 2019

This article aims is to explores an issue where Sustainable finance itself is a form of embodiment in Article 33 paragraph (4) of the 1945 Constitution of the Republic of Indonesia that the national economy is organized based on several principles, one of which is sustainable principles by maintaining a balance and unity of the national economy. Thus Article 33 paragraph (4) of the 1945 Constitution of the Republic of Indonesia is a juridical basis of sustainable finance that promotes a sustainable financial system. The research methodology was an integration of empirical juridical research methods and interpretation of the normative method results. The results indicated that with the involvement of banks in implementing sustainable finance, banks must be selective in granting credit to debtors by setting conditions that are following bank policies. Because basically, sustainable finance activities do not harm the community, it creates justice for the community based on the constitutional rights of citizens to get a decent life. In the concept of sustainable finance, economic sustainability includes several criteria in carrying out credit risk analysis, including sustainability of resources, the sustainability of results and sustainability of the business.
