In a two-cut, alternate strip clearcutting system in upland black spruce, the main factors influencing black spruce regeneration in the first-cut strips were strip width, natural seeding period, amount of receptive seedbed and topographic position. In the three study areas, 80-m strips yielded over 60% stocking and over 7 500 seedlings per hectare with a 4-year natural seeding period. Narrower strips 40 m and 20 m wide showed increasing levels of reproduction. Four years of natural seeding gave better natural regeneration than two years. Seedling density and frequency in quadrats were correlated with the amount of receptive seedbed. Regeneration was more abundant on drainageways and lower slopes, and less abundant on upper slope and crest sites. For successful regeneration under similar climatic and physiographic conditions, strip widths should be no more than 80 m, and leave times no less than 3 years. It is essential to scarify the upland mineral soil sites, but scarification of lowland sites is not recommended, especially where there is abundant Sphagnum.

The purpose of this paper was to give an overview of economic development under reform and world integration and to evaluate the main factors influencing the growth of the Vietnamese economy during the reform period (1990-2009). Based on statistical data on the Vietnamese economy in the period of 1990-2009, this study analyzed the factors affecting economic growth. The policy changes, economic development, poverty rates and living standards of Vietnamese population are analyzed over the reform period using qualitative methods. The results of this study show that economic growth under reform and world integration has reduced the poverty rate and increased living standards of population in Vietnam. An evaluation of the factors influencing economic growth is made using a quantitative model of total factor productivity (TFP) and another econometric model. The findings from this quantitative analysis show that the growth of the Vietnamese economy was determined by two factors: (1) capital investments, including foreign direct investment (FDI) and (2) the growth of exports. The results of these qualitative and quantitative analyses lay the foundation for policy recommendations for Vietnam Government to develop economy in the future.

The general aim of the present chapter is to focus on the factors influencing simulation-based computersupported inquiry learning in small groups. The authors will give an overview of research that describes different factors influencing inquiry learning and problem solving and will add a dimension of collaborative web-based inquiry from their studies. The evidence from relevant scientific literature as well as the empirical results collected by the authors form the basis for discussion about designing an effective learning environment through a viewpoint of different end-users of our results – especially teachers and software designers. As a result, three additional main factors have been found that should be taken into account in designing support systems for problem solving: i) the level of difficulty of problems, ii) the appropriate sequence of problems, and iii) the characteristics of learners’ groups.

Natural Range

A tool was developed to allow managers and foresters to quickly assess reforestation needs following forest fire and salvage logging at the stand level in both pure and mixed black spruce and jack pine stands. This on-site operational assessment tool was created using a forest regeneration model that simulates the natural regeneration densities of black spruce and jack pine following fire and salvage. Tree species basal areas used for simulations represent the natural range expected in the field. Additional parameters include the abscission schedule of the species, the percentage of optimal (exposed mineral soil or humus) post-fire seedbeds, and the timing of the salvage operation. The tool also allows for rapid planning of both salvage operations and planting. It has important advantages over conventional seedling surveys in that it can be employed immediately following fire, can guide management decisions about the planning of road construction and the harvest sequence, and takes into account the entire establishment phase. Using the tool to adjust the harvesting schedule to minimize replanting, the likely final cost of reforestation can be estimated for an entire burn. The tool shows that a higher percentage of optimal seedbeds are necessary following salvage: (1) for black spruce to regenerate adequately compared to jack pine (i.e., planting of black spruce will almost always be necessary); (2) as basal area of the species of interest decreases; and, (3) to adequately regenerate burned intact and salvaged stands in late-season fires compared with those from early-season fires.

Hypersaline Lagoon

Abstract Cladocera represent an important zooplankton group because of their seasonal prominence in terms of abundance and their contribution in controlling primary production (phytoplankton). On a global scale, there are few studies on Cladocera in hypersaline environments. The present work aims to evaluate the spatio-temporal variation of the Cladocera assemblage across a salinity gradient in the habitats of the Araruama Lagoon. Samples were collected in random months over a period of four years at 12 fixed stations in the Araruama Lagoon using a WP2 plankton net equipped with a flow meter. Our results do not reveal significant influence of the tide and seasonal variation as factors affecting the Cladocera assemblage. Five Cladocera species were found in the Araruama Lagoon, only in stations 11 and 12 where they reached an average of 1,799 ± 3,103 ind. m-3. The mean of the Shannon Diversity Index was 0.45 ± 0.2. The species that stood out in terms of frequency and abundance were: Penilia avirostris (frequency of occurrence: 71%), followed by Pseudevadne tergestina (41%). The same species also stood out in terms of relative abundance, Penilia avirostris (87%) and Pseudevadne tergestina (11%). The absence of Cladocera in the innermost parts of the lagoon suggests that their entrance to these locations is possibly inhibited by the salinity and temperature gradient of the lagoon, being the main factors influencing the dynamics of the Cladocera assemblages.

Bank Perkreditan Rakyat (BPR) is part of  the  banking  financial institutions  apart from the commercial  banking. .One of the activities of the BPR is to distribute the credits as done by the commercial banks. Problems. BPR as micro financial institutions, in doing their business to  distribute  the credit up to certain amount, are faced with  the  commercial banks  which  have more  competitive advantages, both in the price  and facilities provided. Objective of this research is to identify the factors influencing the customers in making decisions to take the credit at BPR. By identifying the determinant factors in choosing the banks, BPR can use it to improve their services to the customers and at the same time BPR can use it as a strategy in  giving credit to the customers or debtors. The metode employed in this study was regressive logistic method, which was  used to  identify  what factors determine the customers to choose credit at BPR. The conclusion is that the procedures and personality of staff are the main factors making the customers choose credit at BPR

The article reflects the main problems of men, which differ from women. The main factors influencing the socio-psychological state of men are determined. The biggest problem men face is the idea that sharing any emotion is considered girly, and that being girls is not what they want to be. The analysis found that men have far fewer cases of being diagnosed with mental illnesses that affect their emotions, such as depression, or disorders resulting from social pressure. They (men) are often silent, depressed. Appropriate professionals such as therapist and psychologist do not address hiding their emotions.
