Current state and trends of Ukrainian civil engineering industry development

Досліджено сучасний стан й особливості діяльності підприємств будівельної галузі України. Розкрито спектр виробничих процесів, які охоплює будівництво як галузь матеріального виробництва. Оцінено стан будівельної галузі шляхом аналізу структури ВВП України та динаміки частки будівельної галузі в структурі ВВП за останні п’ять років. Позитивні тенденції у розвитку будівельної галузі за останні роки характеризуються стабільним зростанням індексу будівельної продукції. Наведено характеристику й аналіз даного показника. Зроблено акцент на розвитку житлового будівництва як основного напряму, завдяки якому сьогодні розвивається будівельна галузь України. Житлове будівництво має особливо важливе соціальне значення, оскільки є складовою, що визначає рівень та якість життя населення. Узагальнено дані статистичних спостережень щодо обсягів інвестицій у житлове будівництво, прийнятого в експлуатацію житла (нове будівництво), а також дачних та садових будинків нового будівництва. Будівництво є складним бізнес-процесом, який включає постійну взаємодію забудовника, підрядника, інвестора, регулюючих органів, фізичних осіб у часі із залученням великих коштів та реалізує комплекс дій, метою яких є планове завершення будівництва та успішного введення об’єкта в експлуатацію. Для подальшого розвитку будівельна галузь потребує значних капіталовкладень, джерелами яких можуть бути як вітчизняні, так і закордонні інвестори. Процедура залучення інвестицій вимагає оцінювання ділової активності будівельних підприємств. Узагальнююч им показником для такого оцінювання є індикатор ділової впевненості в будівництві. За останніх п’ять років даний показник має стійку тенденцію до зростання. Ділову активність будівельних підприємств оцінюють за такими напрямами: оцінювання зміни обсягу виконаних будівельних робіт за попередній період; оцінювання впливу факторів, що стримують будівельну діяльність; оцінювання поточного обсягу замовлень на будівельні роботи; оцінювання зміни кількості працівників; оцінювання зміни цін на роботи, які виконують будівельні підприємства; оцінювання забезпеченості замовленнями будівельних підприємств у майбутньому.The current state and peculiarities of Ukrainian civil engineering enterprises activity are investigated in this paper. The production processes spectrum concerning civil engineering as the branch of material production is revealed. The civil engineering industry state is estimated by analyzing Ukraine GDP structure and dynamics of the civil engineering industry share in GDP structure over the past five years. Positive trends of the civil engineering industry development in the last years are characterized by stable growth in the construction products index. The characteristics and analysis of this index are described in this paper. Emphasis is made on the development of residential construction as the main direction of Ukraine civil engineering industry development today. Residential construction has special social importance as it is the component determining the living standards. The data of statistical observations concerning the amount of investments in resid ential construction, housing introduced into service (new construction), as well as country and garden houses of new construction are generalized. Construction is the complex business process that involves the constant interaction of the developer, contractor, investor, regulators, physical persons in time involving large funds and implements a set of actions aimed at the scheduled construction completion and successful introduction into service. For its further development the civil engineering industry requires significant investments, which can be the source of both domestic and foreign investors. The procedure of attracting investment requires estimation of construction companies business activity. The summarizing indicator for this estimation is the Con struction Business Confidence Indicator. Over the last five years, this indicator has been steadily increasing. Business activity of civil engineering industry enterprises is evaluated in the following directions – assessment of changes in the volume of construction work performed in the previous period; assessment of the impact of limiting construction activity factors; estimation of current orders volume for construction works; estimation of changes in the employees number; estimation of changes in prices for works performed by civil engineering industry enterprises; assessment of future procurement of construction enterprise

Subdiagrams and invariant measures on Bratteli diagrams

We study ergodic finite and infinite measures defined on the path space $X_{B}$ of a Bratteli diagram $B$ which are invariant with respect to the tail equivalence relation on $X_{B}$. Our interest is focused on measures supported by vertex and edge subdiagrams of $B$. We give several criteria when a finite invariant measure defined on the path space of a subdiagram of $B$ extends to a finite invariant measure on $B$. Given a finite ergodic measure on a Bratteli diagram $B$ and a subdiagram $B^{\prime }$ of $B$, we find the necessary and sufficient conditions under which the measure of the path space $X_{B^{\prime }}$ of $B^{\prime }$ is positive. For a class of Bratteli diagrams of finite rank, we determine when they have maximal possible number of ergodic invariant measures. The case of diagrams of rank two is completely studied. We also include an example which explicitly illustrates the proven results.</jats:p

INWESTORZY INDYWIDUALNI JAKO AKCJONARIUSZE SPÓŁEK PUBLICZNYCH W POLSCE

Znaczenie inwestorów indywidualnych można rozpatrywać zarówno z punktu widzenia ichwpływu na rynek akcji, jak i oddziaływania na same spółki. W badaniu pierwszego z tych obszarówoparto się na analizie wielkości obrotów generowanych przez tych uczestników rynku,w przypadku drugiego zaś wykorzystano analizę udziału w organach spółki akcjonariuszy notyfikowanychbędących osobami fizycznymi. Wyniki badań potwierdziły, że w odniesieniu do mniejszejaktywności w handlu akcjami znajdującymi się w wolnym obrocie, zachowania inwestorówindywidualnych powielają wzorce występujące na bardziej dojrzałych rynkach, natomiast niepowielają ich w zakresie bierności akcjonariuszy w ujęciu corporate governance.INDIVIDUAL INVESTORS AS SHAREHOLDERSOF PUBLIC COMPANIES IN POLANDThe importance of individual investors can be examined taking into consideration theirinfluence on equity market and their impact on stock issuers. The investigation of the first of theabove was based on the analysis of turnover generated by these stock market participants. In caseof the second problem, the analysis of participation of notified shareholders being individualpersons in company authorities was performed. The results of the study prove that relative to loweractivity in free float equity transactions, the behavior of individual investors duplicate patternsfrom more mature markets, however it does not copy this behavior in when it comes to theshareholders passiveness in terms of corporate governance

Reputation as an Institution: An Attempt to Conceptualize and Measure Issues

The article deals with the problem of identifying institutions and measuring them. As an example, reputation was taken into consideration. The analysis leads to the conclusion that reputation could be treated as an institution and could be measured in the context of its impact on economic outcomes. This measurement can be carried out at three levels of detail: micro, meso and macro, of which the third is the least recognized in new institutional economics.The “Annales. Ethics in Economic Life” is affiliated and co-financed by the Faculty of Economics and Sociology of the University of Lodz

The effect of free radical enhancers and scavengers on accumulation of early light-inducible protein during light stress

Involvement of active oxygen species in the accumulation of early light-inducible protein (ELIP) in mature pea plants was investigated under light stress conditions. Here we provide evidence th at hydroxyl radicals and singlet oxygen interfere with ELIP expression at both, transcriptional and posttranslational levels. Addition of free radical scavengers can alleviate the detrimental action of the radicals almost completely at the level of transcription but only a partial protection was observed at the level of proteins. The data suggest that the damage of ELIP occurs during its insertion into thylakoid membranes close to the free radical sources

Competing impurities and reentrant magnetism in La(2-x)Sr(x)Cu(1-z)Zn(z)O(4) revisited. The role of the Dzyaloshinskii-Moriya and XY anisotropies

We study the order-from-disorder transition and reentrant magnetism in La(2-x)Sr(x)Cu(1-z)Zn(z)O(4) within the framework of a long-wavelength nonlinear sigma model that properly incorporates the Dzyaloshinskii-Moriya and XY anisotropies. Doping with nonmagnetic impurities, such as Zn, is considered according to classical percolation theory, whereas the effect of Sr, which introduces charge carriers into the CuO(2) planes, is described as a dipolar frustration of the antiferromagnetic order. We calculate several magnetic, thermodynamic, and spectral properties of the system, such as the antiferromagnetic order parameter, the Neel temperature, the spin-stiffness, and the anisotropy gaps, as well as their evolution with both Zn and Sr doping. We explain the nonmonotonic and reentrant behavior experimentally observed for T_N by Hucker et al. in Phys. Rev. B 59, R725 (1999), as resulting from the reduction, due to the nonmagnetic impurities, of the dipolar frustration induced by the charge carriers (order-from-disorder). Furthermore, we find a similar nonmonotonic and reentrant behavior for all the other observables studied. Most remarkably, our results show that while for x=2% and z=0 the Dzyaloshinskii-Moriya gap \Delta_{DM}=0, for z=15% it is approximately \Delta_{DM} = 7.5 cm^(-1). The later is larger than the lowest low-frequency cutoff for Raman spectroscopy (~ 5 cm^(-1)), and could thus be observed in one-magnon Raman scattering.Comment: 13 pages, 10 figure

The type 4 metallothionein from Brassica napus seeds folds in a metal-dependent fashion and favours zinc over other metals

The problem of handling zinc in the cell is of great importance because zinc is an indis-pensable micronutrient involved in most physiological processes in all living organisms. Moreover, our understanding of mechanisms governing the discrimination between mi-cronutrients and toxic metals on the level of individual proteins to the whole-organism level is incomplete. Metallothioneins are able to bind heavy metal ions, and roles in zinc homeostasis have been proposed. Here, we have studied the in vitro and in vivo metal-binding abilities of Brassica napus type 4 metallothionein (BnMT4) and its expression in germinating seeds in response to metal treatment. Our studies on the regulation of MT4 expression by metals at early stages of ontogenic development revealed for the first time that the mRNA levels of BnMT4 were elevated in response to cadmium and zinc. Given this unexpected metalloregulation, and the dramatic differences in protein folding as de-tected by 1H NMR spectroscopy, we suggest that the BnMT4 protein may not only have a role in zinc homeostasis in early ontogenesis, but also the potential to discriminate be-tween zinc and cadmium, perhaps via differential recognition of Cd- and Zn-complexes by cellular components involved in protein turnover
