Recycling or Rubbish? Understanding Decision-Making in Household Recycling Programs
Authors: Browne C. A. , Moloney B. 
Published: August 2020

Abstract
Material recycling is an increasingly complex global problem. Unprecedented levels of material consumption across developed economies and continuous innovation around materials and manufacturing within the economy have made the practical challenge of closing the loop in recycling increasingly difficult. At the same time, political decisions at the global scale, such as exported recyclables not meeting standards for processing, are forcing local municipalities and councils to reconsider their approach to curbside recycling systems. In recent decades, local councils in Australia have tried various methods, such as education and awareness training, for decreasing contamination of recyclable material in curbside recycling bins. These efforts have been shown to have had a limited effect. To investigate this phenomenon at a local level, we conducted a practical workshop and knowledge experiment with undergraduate engineering students. Students were given a worksheet where they were required to sort household items into curbside recycling, drop-off recycling, or landfill. In this experiment, there were two intervention groups: a picture-based intervention and slogan-based intervention. We found that students in both groups were able to more reliably sort items intended for the Recycling waste stream than the Landfill waste stream. Further, we found that waste education interventions did little to improve correct sorting of items in the Recycling waste stream but did make a difference for Landfill items. This shows that methods for improving communication about material waste streams are needed to improve end-of-life disposal efforts, even within a cohort of young adults who have a background in engineering materials.

Abstract
A Rosaceae family-level candidate gene approach was used to identify genes associated with sugar content in blackberry (Rubus subgenus Rubus). Three regions conserved among apple (Malus × domestica), peach (Prunus persica), and alpine strawberry (Fragaria vesca) were identified that contained previously detected sweetness-related quantitative trait loci (QTL) in at least two of the crops. Sugar related genes from these conserved regions and 789 sugar-associated apple genes were used to identify 279 Rubus candidate transcripts. A Hyb-Seq approach was used in conjunction with PacBio sequencing to generate haplotype level sequence information of sugar-related genes for 40 cultivars with high and low soluble solids content from the University of Arkansas and USDA blackberry breeding programs. Polymorphisms were identified relative to the ‘Hillquist’ blackberry (R. argutus) and ORUS 4115-3 black raspberry (R. occidentalis) genomes and tested for their association with soluble solids content (SSC). A total of 173 alleles were identified that were significantly (α = 0.05) associated with SSC. KASP genotyping was conducted for 92 of these alleles on a validation set of blackberries from each breeding program and 48 markers were identified that were significantly associated with SSC. One QTL, qSSC-Ruh-ch1.1, identified in both breeding programs accounted for an increase of 1.5 °Brix and the polymorphisms were detected in the intron space of a sucrose synthase gene. This discovery represents the first environmentally stable sweetness QTL identified in blackberry. The approach demonstrated in this study can be used to develop breeding tools for other crops that have not yet benefited directly from the genomics revolution.
Estimation of Natural Selection and Allele Age from Time Series Allele Frequency Data Using a Novel Likelihood-Based Approach
Authors: He Zhangyi , Dai Xiaoyang , Beaumont Mark , Yu Feng 
Published: August 2020

Abstract
Temporally spaced genetic data allow for more accurate inference of population genetic parameters and hypothesis testing on the recent action of natural selection. In this work, we develop a novel likelihood-based method for jointly estimating selection coefficient and allele age from time series data of allele frequencies. Our approach is based on a hidden Markov model where the underlying process is a Wright-Fisher diffusion conditioned to survive until the time of the most recent sample. This formulation circumvents the assumption required in existing methods that the allele is created by mutation at a certain low frequency. We calculate the likelihood by numerically solving the resulting Kolmogorov backward equation backward in time while reweighting the solution with the emission probabilities of the observation at each sampling time point. This procedure reduces the two-dimensional numerical search for the maximum of the likelihood surface, for both the selection coefficient and the allele age, to a one-dimensional search over the selection coefficient only. We illustrate through extensive simulations that our method can produce accurate estimates of the selection coefficient and the allele age under both constant and nonconstant demographic histories. We apply our approach to reanalyze ancient DNA data associated with horse base coat colors. We find that ignoring demographic histories or grouping raw samples can significantly bias the inference results.
Mentality management: Mentality formation and strategy development
Authors: Voinycha Liliia , Popivniak Roman 
Published: August 2020

The goal of this article is to analyze problems relating to the mindset of the Ukrainian people as it pertains to Ukraine’s integration into the European Union. Several different methods were used in this analysis. Comparative analysis identified similarities and differences between the peoples of the European Union and Ukraine. Also, an abstract-logical method was used to define the main problems relating to state support for democracy in Ukraine. Finally, a statistical-economic method was used to identify the existence and closeness of the connection between the standard of living and the perpetuation of corruption in Ukraine. The work analyses the principal directions and problems of mentality management for the people of Ukraine and finds that the strategy development for the Ukrainian personality should be focused not only on the self-improvement of each individual but also on developing practical recommendations for strengthening the democratic foundations of Ukrainian society.
Menedzserizmus a felsőoktatásban: érvek, ellenérvek, alternatívák
Authors: Kováts Gergely 
Published: August 2020

Absztrakt:
Az elmúlt évtizedek felsőoktatási reformjainak egyik kiemelt célja az
eredményesebb intézményi működés elérése volt, amelyet a menedzsment
megerősítésével kívántak elérni. A menedzserizmus azonban az egyetem
diszfunkcionális működését is eredményezte. A tanulmány alapkérdése, hogy milyen
alternatívái fogalmazódnak meg a menedzserizmusnak azokban az országokban, ahol
ez vált az uralkodó egyetemszervezési megközelítéssé. A cikk áttekinti a
menedzserizmus kialakulásának okait és kritikáját, néhány ellenállási és
reformstratégiát, valamint illusztrációként bemutat egy egyedi irányítási
gyakorlattal rendelkező egyetemet, a szövetkezeti elvekre épülő Mondragon
Egyetemet.
A reformjavaslatok egyike sem vágyódik vissza az elefántcsonttoronyba, és egyik
sem vitatja a hatékonyság és eredményesség fontosságát. Mindegyik úgy véli
azonban, hogy a menedzserizmusnál vannak jobb módok, amelyek a hatékonyság
elérése mellett a közösség és az érintettek érdekeit teljesebben meg tudják
jeleníteni és jobban ki tudják egyensúlyozni. Mindegyik javaslat kiemeli a
döntéshozási folyamatok demokratizálásának szükségességét, ami elengedhetetlen
feltétele az egyetem megújulásának

Cikkünkben a társadalmi vállalkozások és a felsőoktatás lehetséges kapcsolatát,
kapcsolódásait járjuk körül elsősorban abból a szempontból, hogy a társadalmi
vállalkozás viszonylag új koncepciója miképp hathat a felsőoktatási intézmények
működésére. Ezt a kérdést – a társadalmi vállalkozás fogalmának körbejárását
követően – három irányból látjuk izgalmasnak vizsgálni: elsőként bemutatjuk a
társadalmi vállalkozás koncepció néhány lehetséges hatását a felsőoktatási
intézmények működésére; ezt követően a tématerület megjelenését tekintjük át a
felsőoktatásban, fókuszálva a gazdálkodástudományok területére; végezetül
elemezzük a társadalmi vállalkozásokhoz való kapcsolódást egy úgynevezett
science shop tapasztalatai alapján, amelyet a felsőoktatási
intézmények harmadik missziójának egyik megvalósítási módjaként tartanak
számon.
Kooperációs tanulási kísérlet iskolai osztályteremben

Absztrakt:
Két kísérlet eredményeit mutatjuk be a cikkben. A kísérleteket az Elliot Aronson
által kifejlesztett mozaikmódszerrel végeztük abból a célból, hogy kimutassuk a
kooperációs tanulási módszer előnyeit az osztályteremben zajló tanulás során. A
kooperáció evolúciós biológiai és szociálpszichológiai értelmezése alapján azt
vártuk, hogy az együttműködés pozitív hatást gyakorol a tanulók egyes szociális
készségeinek alakulására. Kiderült, hogy ez a várakozás csak bizonyos feltételek
között igaz. A nyolcadikos, iskolaváltás előtt álló diákok kevésbé hajlanak a
kooperációra, s a biológia mint tantárgy is kevéssé alkalmas a módszer
alkalmazására. Fiatalabb korú diákok és diszkurzív tantárgy esetén viszont a
kooperatív módszer alkalmazása előnyös.
The health psychology approach to normal ageing
Authors: Hoyer M. 
Published: August 2020

AbstractApproaching the process of normal ageing with a health psychology model was an important development in health science. In earlier healing models, questions of old age were either ignored or dealt with only in the context of various diseases. Definitions of the stages of human life have changed and pushed the limits of old age to a higher level. The expanding human life course raises important medical, psychological, and sociological issues. The definition of ageing and the characteristics of normal ageing need to be reconsidered. The cognitive representations of ageing people are a good reflection of how they think about themselves, the world, and the stage of life ahead. The contribution of health psychology as a modern approach to healthy ageing has greatly altered the attitudes of healthcare professionals. The concept of active old age helps to deal with the growing number of elderly people in a new context. In this brief overview of the health psychology approach to normal ageing, we aim to help healthcare professionals better manage the problems in their daily work. In a brief introduction, we review the physical and mental symptoms of ageing. We strive to isolate the normal variants from gerontopsychiatric and neuropsychiatric disorders. While normal ageing does not require clinical attention, psychiatric disorders do, and we briefly describe the therapeutic forms. Psychoeducation, group therapy, and supportive techniques prove to be the most effective.

Household electricity usage optimization using MPC and mixed integer programming
Authors: Taik Salma , Kiss Bálint 
Published: August 2020

Abstract
This paper discusses the control of the electric energy consumption in a household equipped with smart devices. The household consumption pattern is the result of a two-level optimization framework. The scheduling of the electric appliances is determined by the first optimization, receiving Time of Use tariffs proposed by the utility company. The scheduler considers the consumer's preferences on the powering on for each appliance.
Secondly a model predictive controller is developed to control the electric heating system based on energy constraints resulting from the appliance scheduling.
Simulations show the energy efficiency and an optimized electricity cost of the strategy proposed.
Analysis of movement of persons with disabilities during evacuation by lift
Authors: Szénay Martin , Lopušniak Martin 
Published: August 2020

Abstract
Lifts are indispensable for the evacuation of mobility-impaired people from buildings in case of emergency. It is necessary to quantify the movement parameters of these people and describe the entire process using a suitable algorithm. The aim of the research was to quantify the times and speeds of movement for a person using a wheelchair and for an injured person. An experiment in situ was used. During the experiment, arrivals at the lift, cabin entries, and exits were monitored. The results include the times and speeds of a mobility-impaired person's movement. The experiments showed that a person using a wheelchair was slower than an injured person. The results can be used to expand computational models to account for the possibility of using lifts for evacuation.
Analysis and balance of phosphorous removal from wastewater at urban wastewater treatment plant
Authors: Lukac Peter , Jurik Lubos 
Published: August 2020

Abstract:Phosphorus is a major substance that is needed especially for agricultural production or for the industry. At the same time it is an important component of wastewater. At present, the waste management priority is recycling and this requirement is also transferred to wastewater treatment plants. Substances in wastewater can be recovered and utilized. In Europe (in Germany and Austria already legally binding), access to phosphorus-containing sewage treatment is changing. This paper dealt with the issue of phosphorus on the sewage treatment plant in Nitra. There are several industrial areas in Nitra where record major producers in phosphorus production in sewage. The new wastewater treatment plant is built as a mechanicalbiological wastewater treatment plant with simultaneous nitrification and denitrification, sludge regeneration, an anaerobic zone for biological phosphorus removal at the beginning of the process and chemical phosphorus precipitation. The sludge management is anaerobic sludge stabilization with heating and mechanical dewatering of stabilized sludge and gas management. The aim of the work was to document the phosphorus balance in all parts of the wastewater treatment plant - from the inflow of raw water to the outflow of purified water and the production of excess sludge. Balancing quantities in the wastewater treatment plant treatment processes provide information where efficient phosphorus recovery could be possible. The mean daily value of P tot is approximately 122.3 kg/day of these two sources. The mean daily value of P tot is approximately 122.3 kg/day of these two sources. There are also two outflows - drainage of cleaned water to the recipient - the river Nitra - 9.9 kg Ptot/day and Ptot content in sewage sludge - about 120.3 kg Ptot/day - total 130.2 kg Ptot/day.
Formex algebra adaptation into parametric design tools and rotational grids
Authors: Sárközi Réka , Iványi Péter , Széll Attila Béla 
Published: August 2020

Abstract:This paper describes the adaptation of the formex configuration processing to the computer program Grasshopper 3D and focuses on the applied mathematical solutions. Formex algebra is a mathematical system, primarily used for planning structural systems like truss-grid domes and vaults, together with the programming language Formian. The goal of the research is to allow architects to plan truss-grid structures easily with parametric design tools based on the versatile formex algebra mathematical system. To produce regular structures, coordinate system transformations are used. Owing to the abilities of the parametric design software, it is possible to apply further modifications on the structures and gain special forms. The paper covers the basic dome types, and it introduces additional dome-based structures using special coordinate-system solutions based on a spherical coordinate system, vault structures and their modifications based on a cylindrical coordinate system and circular structures and their modifications based on polar coordinates. Moreover two rotational grid tools are introduced, which uses coordinate system transformations on a unique way to create surfaces of revolutions based on the given generating curve and create grid structures on these surfaces. It also describes the solution technique to implement the triangular grid version of every one of these tools based on diamatic domes. The adaptation of formex algebra and the parametric workflow of Grasshopper together give the possibility of quick and easy design and optimization of special truss-grid domes.
Optimized room arrangement and building shaping of an industrial and office facility
Authors: Androsics Tamás , Baranyai Bálint 
Published: August 2020

Abstract:This paper proposes the application of energy efficient, low tech (passive) building design strategies and concepts in an industrial facility case study, in order to create a building with high efficiency and comfort within the boundaries of a tight investment cost. The planning process is supported by dynamic thermal and daylight simulations. Two versions were considered, a conventional industry building and a low tech one with climate zone based space organization. According to the evaluation of thermal and visual comfort as well as energy demand the selected version with the innovative passive concept delivered considerably better performance. According to the constructor’s concept, the reference building had to be placed by minimal adaptation on the new site. After considering and calling this concept into question, a new ‘energy design’ concept was elaborated at the sketch planning level. The new concept was compared with the reference building and a quantified, simulation assisted evaluation was provided about the cases. Since there was an essential improvement in comfort and energy level and, in addition, at architectural standard, the constructor could have been convinced to accept the new concept.
A comparative evaluation of techniques for N-way joins in wireless sensors networks
Authors: Djail Boubekeur , Hidouci Walid Khaled , Loudini Malik 
Published: August 2020

Abstract:In wireless sensors networks, data are sensed and recorded as databases, and then acceded by relational queries. Joins are queries that are largely used. Joins collect data from several nodes’ table. These are operations that typically consume a lot of energy because they generate a large number of messages in the network. Researchers worked to decrease this consumed energy. Many strategies were proposed in this way, but most of them addressed only binary joins. N-way joins received few interests. N-way joins perform join operations between more than two tables. They cause greater energy consumption. Additionally, the number of execution order is very important; it grows exponentially with the number of considered tables.
