Opis:
Scientificmagazines have published hundreds of research papers on stereotype threat. They indicated that despite their intellectual potential some individuals may experience lower performance in school tasks because of the fear of confirminga stereotype about the low abilities of their social group. Most of the research was of an experimental nature, with the use of a single manipulation within the experiment group and comparing its results to those of the control group. Additionally, despite two decades of research, discrepancies in how the term is definedor in the manipulation and measurement methods persist. The article outlines the development of a tool for measuring the intensity of a sense of low abilities stereotype threat among elementary school pupils (grades IV-VI) and the results of a pilot study. The scale was developed based on the theoretical assumptions of Shapiro’s and Neuberg’s multi-threat concept, which appears to put in order the aforementioned discrepancies in understanding the phenomenon’s essence and the ways it is measured.

Opis:
The study describes a new method of assessing the average age of the forest range with significant share of stands in the regeneration class. In proposed method, average age of stands in regeneration layer is calculated as a mean age of tree layer as well as layer of upgrowth, recruitment and saplings weighed by these layers fraction. Example of calculation of average age was performed for 7 ranges located in Kotlina Kłodzka (SW Poland) with total area of 48 653 ha. Average age of stands calculated by proposed method vary from 62 to 73 years and is lower in comparison to average age calculating according to current regulations from 5 to 14 years. Proposed method of calculation the average age of stands in shelter wood cutting system takes into account composed structure of stands in regeneration period by using age and share of all trees generation in stand.

Opis:
Forest management in the State Forests in the past two decades (1990−2009) focused solely on the aging of forest stands and augmentation of forest resources. This period saw an increase in the average age of forest stands from 54 to 61 years, the average standing volume from 186 to 245 m3/ha, and the share of harvested volume in annual increment volume from 50 to 58%. As a result, the share of stands older than 80 years increased from 21 to 28% while that of plantations and young stands decreased from 14.4 to 11%. This resulted in the deterioration of the health and sanitary condition of forests.

Opis:
The paper is an attempt to evaluate the forest management pursued in the mountains on the basis of the analysis of the volume and structure of Carpathian forest resources in the space of nearly forty years, i.e. from 1967 till 2006. The studies comprised 68 forest divisions (previously having the rank of forest districts) covering an area of 467,226 hectares of forests administered by the State Forests National Forest Holding and forests of the Forest Experimental Station in Krynica. The same research method and research material as in 1967 were used for the comparison of the results. The material included overall inventory results obtained from individual forest divisions, so−called "tables of age classes by dominant species".
