    The relevance of the problem under study is based on the fact that, as regards methodological and theoretical aspects, the problem of value and motivational sphere is poorly elaborated regarding the interrelation between professional education and professional activity and on the empirical level there is no clear understanding of how the sense of purpose of life and own professional values is related to the professional motivation. The aim of the article is to identify the specific features of the interrelation and effects of meaning of life to the professional values and motivation. The leading method of research is questionnaire method which makes it possible to identify the following: level of sense of life’s purpose – method of life-meaning orientations, specific features of professional motivation – method “Motivation of professional activity” and method “Level of correlation between value and availability of value”. The article presents and discusses the results of empirical study of the interrelation between professional values, professional motivation and life-meaning orientations, as well as the effects of the level of life’s meaning on professional motivation. The practical value is the possibility to use the results of the research in developing programs for correcting and increasing professional motivation, as well as for developing technologies of psychology-pedagogical assistance to sense-making and professional self-identification in projecting and implementing individual educational trajectories in the continuous vocational education system. The article can be useful for specialists in professiology, teachers of technical subjects and professional consultants for forecasting professional development of a person. © 2016 Zavodchikov et al

    This is the final version. Available from WIT Press via the DOI in this record. System Dynamics Model (SDM) that explores sustainable urban water management. The model is open-source compiled using Vensim software, which is free for non-commercial use. This paper demonstrates that the current SDM and the modelling approach are open to adjustment, which is illustrated by introducing a link between water tariffs and environmental awareness. The increase in water tariffs leads not only to the obvious increase in water bills, but also to an increase in Environmental Awareness, and consequently, to increases in the use of water efficiency devices, grey water acceptability, and grey water reuse. A range of further modifications is suggested, including expanding representation of sustainable drainage systems (SuDS) to consider resultant improvements in stormwater quality as well as quantity. This would recognise the indirect benefits of improved stormwater quality on biodiversity in the River Ebbsfleet, which is the receiving watercourse. This study intends to encourage knowledge transfer, by facilitating and incentivising the use and further development of the SDM by stakeholders and a wider community of end-users, including practitioners, academics and the public. While SDM is particularly suited to analysis of indirect relations, benefits and trade-offs among system constituents, other approaches provide viable alternatives and we discuss the potential for re-implementing our findings in other interactive modelling software packages and programming languages. We also explore the scope for linking the adapted SDM to other models. Finally, we consider the utility of the Ebbsfleet SDM in teaching, learning and knowledge transfer. We conclude that students, practitioners and other stakeholders could not only enhance their understanding of urban water management complexity, but also gain valuable system modelling skills based on using the SDM to support kinaesthetic learning. Ultimately, society benefits when the level of knowledge and analytical thinking skills of its members are enhanced.Engineering and Physical Sciences Research Council (EPSRC)Engineering and Physical Sciences Research Council (EPSRC)Engineering and Physical Sciences Research Council (EPSRC

    Abstract-The aim of the present paper is to construct and study a model of pair moment interaction between carbon atoms in the two-dimensional graphite lattice. The carbon atom is modeled by a structure consisting of three rigidly connected mass points located at the vertices of an equilateral triangle. The interaction between mass points is described by a pair force potential, but the total interatomic interaction contains moment components owing to the finite size of the structure modeling the atom. We compute rank 4 tensors characterizing the elastic properties of the graphite crystal lattice constructed on the basis of our model. We determine lattice stability criteria depending on the number of coordination spheres taken into account. We show that this model permits one to ensure stability of the graphite lattice but significantly underestimates the transverse-tolongitudinal interatomic coupling rigidity ratio. We construct a generalized moment potential that permits one to obtain a rigidity ratio consistent with experimental data. DOI: 10.3103/S0025654407050020 1. INTRODUCTION A well-known problem in modeling lattices with low packing density is that the use of pair potentials for describing interatomic interactions does not always result in stable lattice models. There are two alternative approaches to resolve the issue. The first approach is based on the use of multiparticle potentials This study is based on the theoretical considerations presented i

    This is the author accepted manuscript. The final version is available from IAHR via the link in this recordThe present work describes the development of a participatory System Dynamics Model (SDM) aiming to explore sustainable urban water management (UWM) in a structured way and to understand where policy interventions might be best focused. The proposed multi-step process is useful for supporting decision-making at a strategic, system-wide level and for exploring the long-term consequences of alternative strategies. The strongly participatory base of the SDM allows both to include local knowledge held by relevant stakeholders, and to support a collective learning process, which should improve the effectiveness of the selected strategies. In the following sections on the SDM co-development to enhance sustainable urban water management in the Ebbsfleet Garden City are provided.Engineering and Physical Sciences Research Council (EPSRC

    ASXL2 is essential for haematopoiesis and acts as a haploinsufficient tumour suppressor in leukemia

    Additional sex combs-like (ASXL) proteins are mammalian homologues of additional sex combs (Asx), a regulator of trithorax and polycomb function in Drosophila. While there has been great interest in ASXL1 due to its frequent mutation in leukemia, little is known about its paralog ASXL2, which is frequently mutated in acute myeloid leukemia patients bearing the RUNX1-RUNX1T1 (AML1-ETO) fusion. Here we report that ASXL2 is required for normal haematopoiesis with distinct, non-overlapping effects from ASXL1 and acts as a haploinsufficient tumour suppressor. While Asxl2 was required for normal haematopoietic stem cell self-renewal, Asxl2 loss promoted AML1-ETO leukemogenesis. Moreover, ASXL2 target genes strongly overlapped with those of RUNX1 and AML1-ETO and ASXL2 loss was associated with increased chromatin accessibility at putative enhancers of key leukemogenic loci. These data reveal that Asxl2 is a critical regulator of haematopoiesis and mediates transcriptional effects that promote leukemogenesis driven by AML1-ETO

    Abstract: The beam attenuation serves as a proxy for particulate matter and is a key parameter in visibility algorithms for the aquatic environment. It is well known, however, that the beam attenuation is a function of the acceptance angle of the transmissometer used to measure it. Here we compare eight different transmissometers with four different acceptance angles using four different deployment strategies and sites, and find that their mean attenuation values differ markedly and in a consistent way with instrument acceptance angle: smaller acceptance angles provide higher beam attenuation values. This difference is due to variations in scattered light collected with different acceptance angles and is neither constant nor easy to parameterize. Variability (in space or time) in the ratios of beam attenuations measured by two different instruments correlates, in most cases, with the particle size parameter (as expected from Mie theory), but this correlation is often weak and can be the opposite of expectations based on particle size changes. We recommended careful consideration of acceptance angle in applications of beam transmission data especially when comparing data from different instruments
