Abstract A rubber agroforest system is a form of land use that considers ecological and economic aspects that are still maintained by the people of Tumbang Mantuhe Village. This study aims to identify and analyze the diversity of vegetation in the agroforest system in Tumbang Mantuhe Village, Gunung Mas Regency, Central Kalimantan. This research uses purposive sampling and the vegetation analysis method. The results showed that the species of vegetation in the rubber agroforest system amounted to 29 species in 23 families. At the seedling level, it is dominated by Macaranga sp. and Xylopia ferruginea; the sapling level is dominated by H. brasiliensis and Syzygium tawahense; the pole level is dominated by Deplanchea bancana and Xylopia ferruginea; at the tree, the level is dominated by H. brasiliensis and Lithocarpus sp. At the seedling, sapling, pole, and tree levels, the diversity values were moderate and the species richness values were moderate to high, and the species distribution was even (stable). The H. brasiliensis agroforest system with various trees in it is a characteristic of local wisdom that the people of Tumbang Mantuhe Village have applied from generation to generation, which provides a balance between ecology and economy.

It is recommended to implement forecasting management models in the area of land use and protection by applying linear programming methods to optimize the size of farms, which land is located in different natural and economic zones. Analysis and assessment of land use in natural-economic zones is a type of management activity for deep understanding of the dialectic of a managed object development and true assessment of its moving forces. This enables to simulate the situation of land use, to identify a specific goal, to choose the means to achieve it and to obtain the optimum result. The implementation of the proposed forecast models of the optimal farm size is carried out by linear programming in three ways (northwest corner method, minimum cost method and What-If analysis method, that uses Solver, a Microsoft Excel add-in program). The implementation of the above approaches is based on the example of four farms and five natural-economic zones. The obtained solutions show that the best result is attained by using Solver for What-If analysis method, a Microsoft Excel add-in program. The northwest corner method gives the worst result, but this is the simplest solution. The minimum cost method depends on the researcher qualification and produces the result that is most often found between the results obtained by the northwest corner method and the "Solver" procedure. When using the method of the northwest corner a program of consideration of different options for the distribution of land resources and the choice of the optimal solution was developed. This allows to find an optimal result of land allocation according to the result, which is similar to the result of the procedure "Solver", but it is more adapted for the direct participation of the researcher in the process of solving problems. There is an opportunity to improve the result by changing the original data, which simulates the forecast of the distribution of farm land in natural-economic zones, while minimizing production costs. In the absence of access to computers, the solutions obtained by the northwest corner and the minimum cost methods can be improved by the potential method.

The importance of managing weeds in seminatural habitats that are adjacent to farm fields is unclear. Weedy-margin vegetation may harbor pests or pathogens and may ALSo serve as source populations for ongoing immigration of weeds into the field. It is ALSo possible, however, that margin vegetation provides habitat for organisms that consume weed seeds or suppress the likelihood of pest or pathogen outbreak. We examined the nature of margin habitat using spatial-scaling of Weed-Species richness as an ecological assay. In 2003, we recorded the occurrence of weedy species along the perimeters of 63 fields in Wisconsin. The fields were distributed within six counties that differed in topography, geological history, local climate, and soil type and which spanned the range of variability in the agricultural landscape. We identified seven habitats that differed in geology and land use. The relationship between species richness and margin class was estimated using an analog of the power law. Additionally, we investigated broadscale correlates of habitat heterogeneity at the field level, using a modeling strategy that included additional explanatory factors logically connected to plant diversity. Using a model-confrontation approach, the survey supported the inclusion of two topographical diversity indices, elevation gradient and a field-shape index, into our model. Our broadscale survey provides information on one of a suite of important considerations needed to make decisions about the importance of managing weeds in field margins.

<p>The purpose of this study was to analyze the availability and usability of aids for dyslexia according to the experiences of people with dyslexia. This was a qualitative study in which people with dyslexia were asked to participate by filling out a qualitative survey. The analysis followed the principles of qualitative content analysis method. Participants (N=11) were 15-65-year-old Finnish people with diagnosed dyslexia who use aids for dyslexia regularly. The purpose of this study was to answer the following research questions: (1) How do the people with dyslexia describe the importance of the aids for dyslexia in their everyday life and learning?; (2) Which aids for dyslexia do the people with dyslexia consider the most usable and beneficial?; and (3) What challenges have the people with dyslexia faced when using aids for dyslexia? According to the findings, aids for dyslexia were considered irreplaceably important and supported everyday life in numerous ways. The participants reported that they used aids in many areas of life, such as in school, work, and leisure. The most usable aids were computers (especially word processing soft wares), tablets, and smart phones. Most of the participants had used one or more of them. The biggest challenges were the expensiveness of aids and difficulties in learning to use aids. As the knowledge about dyslexia and number of diagnoses increase, new studies on the possible aids and their developmental needs are required. Versatile aids can provide personal help and support the coping of people with dyslexia in many areas of life. Furthermore, the study showed that, based on the participants’ experiences, more attention should be paid on the product development of aids for dyslexia in the future.</p>

Land Use Effects

Here, we examine the effects of adjacent land use in a managed forest on pond-breeding amphibian species richness and community composition at 34 New Brunswick, Canada, ponds. Amphibian species richness was negatively correlated with the proportion of roads, precommercial thinning, and hardwood forest and positively correlated with the proportion of wetlands in adjacent lands. These land-use effects peak at 180 m from the ponds. Road density was negatively correlated with Lithobates catesbeiana and Lithobates septentrionalis presence. Precommercial thinning was negatively correlated with Ambystoma spp. presence and positively correlated with Anaxyrus americanus presence. Wetlands were positively correlated with L. septentrionalis and Notopthalamus viridescens presence. Correlations were also found between water table height and A. americanus, Lithobates palustris , and Ambystoma spp. presence. In addition, L. catesbeiana and N. viridescens presence–absence was positively correlated with the proportion of mature and overmature forest on the landscape (at scales of 500 and 1000 m, respectively). Lastly, the proportion of regenerating and sapling forest on the landscape was negatively correlated with L. palustris presence–absence but, by contrast, was positively correlated with A. americanus. These results suggest that the effects of adjacent land use may significantly impact amphibian populations in managed eastern Canadian forests.

Vegetation is one factor that can decrease carbon accumulation in the atmosphere. The diversity of plant species in each land use has different abilities to absorb carbon in the atmosphere. This research was conducted in Pesisir Barat Regency of Lampung Province on 4 (four) types of land use, namely: (1) natural forest in Balai Kencana Resort, Bukit Barisan National Park (2) oil palm plantation in Pekon Marang, (3) coffee plantation in Pekon Suka Mulya, and (4) agroforestry of repong damar in Pekon Pahmungan. This reserach aims to analyze the diversity of plant species and to calculate the potential of plant carbon stock and carbon sequestration (above ground biomass) using alometric equations in various types of land use in Pesisir Barat Regency. The research method was vegetation analysis to learn about the diversity of plant species and calculation of carbon stock using alometric equations. The results showed that the composition of plant species in Bukit Barisan NP found 83 plant species belonging to 37 families, in the palm plantation found 9 plant species belonging to 8 families, in the coffee garden found 17 plant species belonging to 11 families, and in agroforestry of repong damar found 73 plant species belonging to 33 families. The total carbon stock potential was 376.16 ton/ha and carbon sequestrated. 1 257.20 ton/ha with the highest carbon uptake available at repong damar agroforestry site of 901.11 ton/ha.Keywords: aboveground biomass, carbon, diversity, pesisir barat regency

Marginalized Families

On the basis of data collected during fieldwork in the city of León, Nicaragua, this article discusses the paradox of many Nicaraguan parents describing their children’s school as being free of charge despite the fact that they are frequently asked to pay for it. The article shows that, in spite of the constitutional definition of education as free and equal for all Nicaraguans, parents are often asked for economic contributions. By analysing the values surrounding the school I suggest that values of responsibility and solidarity influence the way that parents conceptualize their school expenditures and, in relation to this, confirm the status of the school as free. Furthermore, the article describes how Nicaraguan parents often compare the school to their home and describe the relation between teacher and students by using family terms. Inspired by the theory of the American sociologist James Carrier, I argue that this comparison, in addition to the values of responsibility and solidarity, further influences the way Nicaraguan parents and children experience their economic contributions. Finally, I argue that even though the users of the school describe it as free of charge, it remains necessary to recognize its economic aspects, since a lack of recognition can turn out to have important individual and social consequences for the people involved, especially, for the most economically marginalized families.
