EVALUASI 35 TAHUN (1970 – 2005) PENGELOLAAN HUTAN ALAM DI KALIMANTAN TIMUR

In the New Order era, forest management and utilization in East Kalimantan does not assure the sustainability of wood production. Forest has tended to be depleted and degraded instead, characterized by lack of special kinds of wood and change in forest structure due to uncontrolled deforestration. In this sense, natural forest could be beneficially managed if expected value in the long term equal to current value. This is the importance of local government capital share in the forest management. Apart of that, forest management in the previous period has contributed to the creation of labor market and income generation for the worker. However, there seems to be factual that forest industry was unable to produce tricle down effect for the people lived surround the forest. This paper tries to evaluate the policy and practice of forest management during New Order and Reform era, particularly in line with the effort of promoting social welfare in East Kalimantan.Keywords: Pengelolaan hutan lestari, Kalimantan Timur

Migratory and grazing behavior of copepods and vertical distribution of phytoplankton

The vertical distribution and grazing activity of copepods was studied during the summer of 1985 throughout the North Sea. In most areas, copepods did not vertically migrated and their vertical distribution followed that of the phytoplankton which was restricted to the upper 20-30 m. This behavior may be a consequence of barely sufficient or limiting food concentrations (about 200 mg multiplied by m-3. The diel grazing patterns as a function of variations in phytoplankton are described for the dominant zooplankton species: Calanus finmarchicus, Oithona similis, Temora longicornis, Pseudocalanus elongatus, Acartia spp., Centropages hamatus, Microsetella spp</i

Calculations of zooplankton grazing rates according to a closed, steady-state, three-compartment model applied to different¹⁴C methods

A re-examination of the numerical example of the three-compartment model by CONOVER & FRANCIS (1973) showed that the warning by these authors for the misuse of radio isotopes in transfer studies within food chains is incorrect and based on a misinterpretation of their results. There is no difference in the estimate of transfer rate by use of specific activities or by use of total radioactivities observed in each compartment.After adapting the formulae developed by CONOVER & FRANCIS, their model was used to illustrate deviations of the programmed grazing rate in 3 types of grazing experiments; a) with 14C present only in the phytoplankton at the start of the experiment, b) with 14C only in the water, and c) with 14C in both phytoplankton and water. Up to a duration of the grazing experiment of 2 hours, and at various light conditions and grazing pressures, deviations were small and did not exceed 4%. These results are not directly applicable to practical work because the quantitatively important loss by egestion of radioactive material was not accounted for, only losses by respiration were incorporated in the closed, steady-state model.Best calculations of the community filtering rate (fraction of the volume of the grazing vessel swept clear per day) were generally obtained with the formula (with t in hours) lsquo((DPM zoo at time t)/(DPM phyto at 0+DPM phyto at t)/2)×24/trsquo, applicable to all three types of grazing experiments considered

Global Justice Protest Events and the Production of Knowledge about Differences

Recent social movement activities – in particular, transnationally-coordinated global justice mobilizations – require participants to work across substantial differences in languages, cultural backgrounds, political visions, and organizing traditions. Negotiating such differences is an active, adaptive, and learning-intensive process. In contrast to more institutionalized settings such as schools and workplaces, where tropes like “multiculturalism” figure prominently in treatments of “difference,” I argue that knowledge production in social movement settings cultivates a more intensely relational and dynamic disposition towards differences.Les activités récemment menées par les mouvements sociaux – plus spécifiquement, les mobilisations transnationales de justice globale – amènent les participants à collaborer au-delà de différences parfois substantielles de langues, origines culturelles, visions politiques et traditions d’organisation. La négociation de ces différences s’incarne dans un processus actif et nécessite un effort intense d’adaptation et d’apprentissage. Contrairement aux milieux institutionnels – écoles ou milieux de travail – où les rhétoriques telles que le multiculturalisme oriente de manière évidente la gestion des différences, je soutiens que la création de connaissances au sein des mouvements sociaux favorise une disposition dynamique et intensément relationnelle envers les différences

The Nebraska COVID-19 Early Care and Education Provider Survey II: Experiences, Economic Impact, and Ongoing Needs

The Nebraska COVID-19 Early Care and Education Provider Survey II, released in early August 2020, is a second survey following The Nebraska COVID-19 Early Care and Education Provider Survey that was conducted in March 2020. Both surveys were conducted by the Buffett Early Childhood Institute at the University of Nebraska. Results from the March 2020 survey suggested that the coronavirus was negatively impacting early care and education professionals in Nebraska. Imminent threats of illness and directives for enhanced cleaning and precautionary methods (e.g., social distancing) were causing child care providers to experience high levels of stress. They were struggling to access accurate information and cleaning supplies and were fearful of the economic repercussions of decreasing enrollment and/or closure. Nebraska’s agencies, philanthropies, and local communities mobilized to provide resources, and federal funding was made available to small businesses via the CARES act. This second survey examined how licensed family home-based and center-based child care providers in Nebraska have accessed financial supports, how they are coping in the midst of an ongoing pandemic, and what they still need to provide the essential service of early care and education. The current survey, administered in mid-June 2020 to licensed child care providers across Nebraska, reveals a resilient and dedicated workforce struggling economically and coping with very high levels of stress
