Cadastral System

The authors describe modern trends in development of the cadastral system. The main features of the procedure of cadastral registration and software systems that act as accounting and registration of automated databases are highlighted. The technological process of maintaining the unified state register of real estate is analyzed in detail. The modern system of information electronic interaction in the real estate register is designated. The role of information and communication technologies in the Russian cadastral system is shown. The authors propose a classification of online services of Rosreestr in a number of ways. The fourth group of online services is allocated as the most promising as it provides opportunities to obtain additional information at the common activity fields of different Executive authorities. The authors conclude that changes in the cadastral system of the Russian Federation are greatly influenced by global trends which in turn are aimed at expanding the functions of the cadastre as an information basis of land management.

Relative Basicity

The relative basicity of fifteen methylethoxysilylalkylamines of the type (CH3)3-m(C2H5O)m.Si(CH2)nNH2 in acetone has been studied by potentiometric titration. For n 1 the basicity increases with increasing m, which is likely due to increasing electronic interaction of the oxygen of acetone with the silicon of silylalkylamines. The basicity of silylmethylamines (n = 1) changes nonsystematically, probably as a consequence of the competing action of opposite effects.

The Impact

Purpose – The purpose of this paper is to provide for Western educators of international Chinese and Confucian Heritage Culture (CHC) students the first integrated review of kiasu, the “fear of missing out”, and its consequences for learning, teaching, and future research. Design/methodology/approach – A review of the economic importance of international Chinese students is provided, followed by consideration of the pedagogical consequences of restricted participation in educational activities by the so-called “silent Chinese student”. Examination of research on international Chinese students and their source cultures established significant gaps and misunderstandings in the generally accepted understandings of CHCs, especially with respect to the actual practices used in Western and Chinese teaching. More importantly, the participation-related implications of kiasu within the context of broader cultural characteristics are described and implications drawn for teaching practices and research. Findings – While many Western university teachers are aware of the “silent Chinese student” phenomenon, few understand its underlying reasons, especially the kiasu mindset and its relationship to other cultural elements. Kiasu actively impedes the interaction of international Chinese students with their teachers and restricts collaboration with peers, thereby limiting educational achievement. Specific tactics for amelioration are reviewed and recommendations are provided, while an agenda for future research is outlined. Practical implications – Western teachers need to normalise and encourage Chinese student participation in class activities using tactics that have been demonstrated to improve outcomes for Chinese students, but that also assist students generally. These include both within-class and electronic interaction tools. Social implications – More culturally sensitive understanding of the impact of cultural differences on teaching effectiveness. While some effective responses to these already exist, further research is needed to expand the skill-set of Western teachers who work with international Chinese students. Originality/value – This paper provides the first systematic integration of the kiasu phenomenon with educational practice and research.

Successive Reduction

1-Hydroxy-1,2,3,4-tetrahydrophosphinoline 1-oxide (2a) was converted via the corresponding acid chloride (2b) into the 1-vinylphosphine oxide (3) which underwent a Michael-like addition with dimethylamine to give 1-(2'-dimethylaminoethyl)-1,2,3,4-tetrahydrophosphinoline 1-oxide (6). The successive reduction of (6) with trichlorosilane, and oxidation with sulphur afforded the phosphine sulphide (7). The reaction of 1-vinyl-1,2,3,4-tetrahydrophosphinoline 1-oxide (3) with N-bromosuccinimide followed by treatment with dimethylformamide gave 1-vinyl-1,2-dihydrophosphinoline 1-oxide which, under mild conditions, underwent Michael-like addition of amines to the vinyl group to give, for example, 1-(2'-propylaminoethy1)-1,2-dihydrophosphinoline 1-oxide. When heated in a sealed tube at 140-150° in water for 60 h this amine was converted into 4-propyl-1,2,3,4,5,6-hexa- hydro-1,5-methano-4,1-benzazaphosphocine 1-oxide. Several related tricyclic compounds including the corresponding phosphines and phosphine sulphides were synthesized. Several of the new aminophosphorus compounds were tested for analgesic activity.
