PARENTS ROLE IN EDUCATION PROCESS AND THEIR RIGHTS, DUTIES IN COOPERATION WITH THE EDUCATION INSTITUTION

Latvia’s educational policymakers already in 2006 pointed out that one of the main obstacles to raising public awareness about the development of education is poor teacher training for working with parents. It means that a full understanding of the educational process by parents and teachers is unthinkable without cooperation. Respectively, cooperation with educational staff, pupils, parents and family, employers, local governments and state institutions, public organizations and society are pointed out as a fundamental principle of education development policy. Alongside with the other equally important basic principles - systemicity, succession, sustainability, accessibility and coordination. In Great Britain, executive representatives recommend actively incorporating parents into educational policies and practices. The inclusion of parents in teaching-related activities alongside prepared teachers has proved to be a useful factor in improving the attendance of school, the quality of teaching and social cohesion. The author thinks that it is necessary to find out the role of parents in the education process both in pedagogy and in jurisprudence. In Latvia, there are no researches done about this topic. The Education Law of the Republic of Latvia defines both the rights and responsibilities of parents. So, it means that it is important to look closer to these rights and responsibilities.

A study of the chelation of 1,3-bis-(tris-(hydroxymethyl)-methylamino)-2-propanol dihydrochloride with copper (II), nickel (II), cobalt (II)

In this study 1,3-bis-(tris-(hydroxymethyl)-methyl­ amino)-2-prapanol dihydrochloride chelates with calcium, manganous, cobaltous, nickelous, cupric and zinc ions were investigated. Potentiometric titrations were performed to obtain information about the stability of the chelates formed. Calcium and manganous ions showed little chelating ability. Cobaltous, nickelous, cupric and zinc ions formed stable chelates when the ratio of the chelating agent Concentration to the metal ion concentration was 1:1 or larger. Job \u27s method of continuous variations was used for determining the composition of the cupric, nickelous and cobaltous chelates and it was found that these metal ions form a 1:1 chelate with l,3-bis-(tris-(hydroxymethyl)­ methyl amino)-2-propanol dihydrochloride. Stability constants of cupric, niekelous and cobaltous ion chelates were determined spectrophoto­ metrically. The logarithms of the stability constants for the metal chelates are: Cu(II)- 6.45, Ni(II)- 4.86, and Co(II)- 3.66. This order of stability of the chelates is in agreement with the Irving-Williams stability series based on the central metal ion

PeaceFounder: centralised E2E verifiable evoting via pseudonym braiding and history trees

PeaceFounder is a centralised E2E verifiable e-voting system that leverages pseudonym braiding and history trees. The immutability of the bulletin board is maintained replication-free by voter’s client devices with locally stored consistency-proof chains. Meanwhile, pseudonym braiding done via an exponentiation mix before the vote allows anonymisation to be transactional with a single braider at a time. In contrast to existing E2E verifiable e-voting systems, it is much easier to deploy as the system is fully centralised, free from threshold decryption ceremonies, trusted setup phases and bulletin board replication. Furthermore, the body of a vote is signed with a braided pseudonym, enabling unlimited ballot types

Holonomic quantum manipulation in the Weyl Disk

It has been shown that a Weyl point in a superconducting nanostructure may give rise to a Weyl disk where two quantum states are almost degenerate in a 2D manifold in the parametric space. This opens up the possibility of a holonomic quantum manipulation: a transformation of the wave function upon adiabatic change of the parameters within the degenerate manifold. In this paper, we investigate in detail the opportunities for holonomic manipulation in Weyl disks. We compute the connection at the manifold in quasiclassical approximation to show it is Abelian and can be used for a phase gate. To provide a closed example of quantum manipulation that includes a state preparation and read-out, we augment the holonomic gate with a change of parameters that brings the system out of the degenerate subspace. For numerical illustrations, we use a finite value of quasiclassical parameter and exact quantum dynamics. We investigate the fidelity of an example gate for different execution times.Comment: For numerical code used in this paper, see https://zenodo.org/record/508904

FINANCIAL VIABILITY OF CIRCULAR BUSINESS MODELS IN TYRE RECYCLING INDUSTRY IN LATVIA

The end-of-life (EOL) tyre recycling industry in Latvia is encountering economic and sustainability challenges, which require solutions by various stakeholders. Improvement of tyre waste management and recycling is important within the context of sustainability and the new streamlining of circular business models. Its importance is also recognized at the European Union level in relation to the further strategic goals and the European Green Deal. In addition, the tyre recycling industry in Latvia demonstrates a relatively unfavourable financial situation, which is one of the most significant factors hindering the introduction of new circular business models. The aim of this research is to clarify the challenges related to the financial viability of tyre recycling companies adopting the new circular business models. The main research methods are literature review, semistructured in-depth interviews, case studies and financial analyses. There are large stocks of EOL tyres and on average just 50 % of them are recycled. The tyre waste management companies are not motivated to supply EOL tyres to recycling companies. On the other hand, due to various reasons, most of the tyre recycling companies are not working with their maximum production capacity. The research results reveal that the tyre recycling companies mostly run traditional and inefficient business models that require large operating costs and ensure comparatively low profitability. In order to enable more efficient and environmentally friendly tyre recycling process, the companies should implement new, investment intensive technologies. Yet, they face critical issues of liquidity and financial returns. Major conclusions are related to the necessity to develop several business models interlinked within one portfolio thus ensuring the manufacturing of various products with higher added value and quality. This may maximise the profits and improve the financial viability of tyre recycling business modelspublishersversionPeer reviewe

Copyright: Copyright 2020 Elsevier B.V., All rights reserved.The end-of-life tyre recycling industry in Latvia faces significant issues on a national level and on a micro business level. The aim of the research is the clarification of opportunities for new circular business models within the tyre recycling industry in Latvia. The main research methods are literature review, semi-structured in-depth interviews, case studies, content analyses, and quantitative statistical analyses, qualitative and descriptive analyses, allowing providing integrative interdisciplinary assessment. In addition, design-thinking methods contributed to conclusions on future opportunities of new tyre recycling business models. The research shows that the system is insufficiently supervised, and it does not facilitate the development of new environmentally friendly technologies and circular business models. A large share of tyres ends up in waste landfills, are incinerated or illegally stored, whereas only a small number of them are recycled. The traditional tyre incineration methods are ineffective and create adverse effects on the environment. Tyre recycling companies in Latvia are not active in adoption of new technologies and business models. This justifies the topicality of the research problem. The research results reveal that globally new opportunities are being actively explored on how to produce higher added value products from materials obtained in the tyre recycling process. In Latvia, it is possible to develop new financially viable circular business models in tyre recycling industry, for instance, by producing tyre-derived aggregates for construction materials or pavement subbases. Besides the need for dynamic innovation capabilities of entrepreneurs, development of new business models in tyre recycling requires collaboration among various stakeholders. In addition, the government has a significant role in implementing the Green Public Procurement for the industries utilizing products gained as a result of tyre recycling.publishersversionPeer reviewe

Long-term treatment with the oncolytic ECHO-7 virus Rigvir of a melanoma stage IV M1c patient, a small cell lung cancer stage IIIA patient, and a histiocytic sarcoma stage IV patient-three case reports

Publisher Copyright: © 2016 International Virotherapy Center. APMIS published by John Wiley & Sons LtdOncolytic virotherapy is a recent addition to cancer treatment. Here, we describe positive treatment outcomes in three patients using Rigvir virotherapy. One of the patients is diagnosed with melanoma stage IV M1c, one with small cell lung cancer stage IIIA, and one with histiocytic sarcoma stage IV. The diagnoses of all patients are verified by histology or cytology. All patients started Rigvir treatment within a few months after being diagnosed and are currently continuing Rigvir treatment. The degree of regression of the disease has been determined by computed tomography. Safety assessment of adverse events graded according to NCI CTCAE did not show any value above grade 1 during Rigvir® treatment. Using current standard treatments, the survival of patients with the present diagnoses is low. In contrast, the patients described here were diagnosed 3.5, 7.0, and 6.6 years ago, and their condition has improved and been stabile for over 1.5, 6.5, and 4 years, respectively. These observations suggest that virotherapy using Rigvir can successfully be used in long-term treatment of patients with melanoma stage IV M1c, small cell lung cancer stage IIIA, and histiocytic sarcoma stage IV and therefore could be included in prospective clinical studies.publishersversionPeer reviewe

Multimodality Treatment of a Colorectal Cancer Stage IV Patient with FOLFOX-4, Bevacizumab, Rigvir Oncolytic Virus, and Surgery

Colorectal cancer is one of the most commonly diagnosed cancers worldwide. The treatment consists of surgical resection, systemic chemotherapy, and new biological agents. One more recently emerging treatment option is oncolytic virotherapy. Although the use of the new treatment methods shows improved overall and progression-free survival, in general, even with the new treatments, mortality remains high and combinations of treatments should be sought to treat patients with colorectal cancer. Here we report a stage IV colorectal cancer patient who received multimodality treatment including bevacizumab, FOLFOX-4, surgery, and the oncolytic virus Rigvir. The patient shows complete pathological remission and remains stable 7.7 years after initial diagnosis. The possible benefits of combining Rigvir oncolytic virus and bevacizumab should be investigated since in vitro research suggests that anti-angiogenesis agents improve viral distribution by altering the microenvironment of the tumor
