Attempts were made to exterminate rabbits at six separate sites; recolonisation was measured over the following two years. Three sites were treated by repeated warren ripping and three by repeated warren fumigation. At all sites the warren treatments were supplemented by shooting and dogging. Two years after treatment, the density of rabbits was 56% of the original density on fumigated sites and 50% on ripped sites. In the first year after treatment, reopened warrens were found more commonly than newly dug warrens; in the second year there were more new warrens than reopened ones. More of the treated warrens reopened on fumigated sites (40%) than on ripped sites (21%). For individual warrens, the number of entrances at treatment and the distance a warren was from untreated rabbit populations were the main factors influencing the probability of reopening. Population density on the periphery of the sites was the main factor influencing the rate of recolonisation of the sites and group control schemes are recommended to minimise recolonisation after control.

The diet of the brown goshawk, Accipiter fasciatus, was studied during 1980-83 near Macclesfield, VIc. Birds made up 63% and mammals 26% of 1769 prey items. Rabbits, Oryctolagus cuniculus, accounted for 95% of mammalian items. Mammals were estimated to contribute more to dietary biomass than birds (54 v.46%). Other animals recorded in the diet were reptiles (Elapidae and Scincidae), insects (mostly Coleoptera and Orthoptera) and crustaceans (Engaeus spp.). Diet composition varied significantly from year to year, from season to season and, during breeding, between territories in close proximity to one another. There were significant differences in the diets of males and females. Males took relatively more birds (52 v.24%), more insects (41 v.21%) and fewer mammals (2 v. 48%). Differences in food between age classes were also significant. Compared to second-year and older birds, first-year birds took relatively fewer mammals (28 v.43%), fewer birds (23 v.49%) and more insects (43 v.0%).

The article discusses the main factors influencing the process of territorial organization of local selfgovernment in the Republic of Buryatia. These are low population density, uneven resettlement, undeveloped transport infrastructure. The tendency of reduction (transformation) of the number of settlements in municipal districts of the Republic of Buryatia and the experience of territorial transformations of municipal formations in the subjects of the Russian Federation are shown. The main risks and benefits of optimizing the territorial organization of municipalities in the region through the merger and liquidation of a two-tier system of local governance are highlighted.

In a seminal 1973 paper, Robert Clark described the very different “cultures” of the first and second year students in a four year clinical psychology PhD programme. The author applies Clark’s template to his own experiences as trainee or trainer in five different counsellor education programmes, one in the US and four in Australia. Each of the programmes, to varying degrees, demonstrates key features of the pattern identified by Clark, where the first year is “therapeutic” and other-oriented, the second is “professional” and self-focused. The author concludes that all the surveyed programmes exhibited some level of “second year crisis”, in which a significant number of students felt abandoned, dissatisfied, or rebellious. The author extends and refines Clark’s developmental analogy (first year = childhood; second year = adolescence) to reflect recent neurological research, in particular, the shift from a right hemisphere-dominant first year of life, prioritising affiliative needs, to a left hemisphere-dominant second year, prioritising autonomy and control. This shift is paralleled later by a more gradual move from a protective, supportive childhood to necessary, but sometimes conflictual, individuation in adolescence. The first two years of a counsellor training programme broadly echo this process, a process exacerbated by the second year internship/placement, in which students must “leave home” and adjust to unfamiliar, potentially less nurturing, authority figures. Finally, the author suggests introducing more rigorous “academic holding” into the first year, and greater attention to “therapeutic holding” of dissident students in the second, hopefully decreasing student dropout, and achieving a better balanced training experience.

Subject. This article examines the issues related to changes in reproduction capacity and heterogeneity of the development of Russian regions. Objectives. The article aims to assess regional differentiation and investigate the main factors influencing the uneven development of the areas. Methods. For the study, we used the methods of comparative and correlation analyses. Results. The article identifies groups of leading and lagging Russian regions and assesses the possibility of convergence of Russian regions according to the analyzed indicators, such as GRP, GRP per capita, and the output of industry. Conclusions. The results obtained can be used when preparing strategic policy documents, spatial development programmes and concepts. The observed heterogeneity suggests that the regions maintain their positions throughout the research period.

The objective of this paper is to document the experience of developing and implementing a second-year course in an engineering professional spine that was developed in a first-tier research university and relies on project-based core courses. The main objective of this spine is to develop the students’ cognitive and employability skills that will allow them to stand out from the crowd of other engineering graduates.The spine was developed and delivered for the first time in the academic year 2010-2011 for first-year general engineering students. In the year 2011-2012, those students joined different programs, and accordingly the second-year course was tailored to align with the different programs’ learning outcomes. This paper discusses the development and implementation of the course in the Electrical and Computer Engineering (ECE) department.

Research in cognitive development has highlighted that early numeracy skills are associated with later math achievement, suggesting that these skills should be targeted in early math education. Here we tested whether tools used by researchers to assess mathematical thinking could be useful in the classroom. This paper describes a collaborative project between cognitive scientists and school board researchers/educators implementing numeracy screeners with kindergarten students over the course of three school years. The Give-A-Number task (Wynn, 1990) was used with first-year kindergarten students and the Numeracy Screener [BLINDED] with second-year kindergarten students. Results indicated that educators (N = 59) found the tools feasible to implement and helpful for exploring their students’ thinking and targeting instruction. The Educators’ feedback also helped inform improvements to the implementation of the tools and future directions for both the schools and the researchers. This work emphasizes the importance of transdisciplinary collaboration to address the research-practice gap.

Influence of abiotic factors and hosts on population dynamics of green lacewing, Chrysoper lacarnea (Stephens) was studied in sunflower, Helianthus annus (Linn.).The maximum number of C. carnea population was found during mid March –mid April in the first year and mid April – mid May in the second year in sunflower crop. The maximum number of host population viz. egg and larva of Helicoverpa armigera and Myzuspe rsicae population were found during mid March –mid April in both the year and correlation studies revealed the positive and significant correlation between larval population of H. armigera, M. persicae and predator C. carnea. While there was no significant relationship found between eggs of H. armigera and C. carnea. The C. carnea population on H. annus during both the year was positively correlated with maximum temperature and found significant,while negatively correlated with relative humidity.However, no significant correlation of C. carnea was found with minimum temperature in both the year.

AbstractCarbon black-filled polymer composites were investigated as sensing materials for organic liquids. Polypropylene and polystyrene which were selected as matrices and various amounts of carbon black were considered as the main factors influencing sensitivity of the composites in view of the percolation theory. Disposable filaments were produced of these materials. Change in their electrical resistivity was measured upon immersion in benzene, toluene, xylene, ethylbenzene and their mixtures. It has been found that studied materials were sensitive to the composition of liquid mixtures of organic solvent. Relationships between the filament response and volumetric fraction of the components were presented. The studied materials have shown promising sensing properties, which suggest their applicability for identification and quantification of multicomponent organic liquids.
