Private forest farming has been a new source of family income for farmers in the Ciamis District. However, it has not been could to fully support the living needs of farmer families. Therefore, a strategy is needed to increase the productivity of private forest lands wich can meet the short-term and long-term needs of farmers. This study aims to identify the superior commodity types of empon-empon wich has the potential to increase the productivity of community forest lands. The study desk method was used in this research by utilizing statistical data on the production of biopharma plants in Ciamis Regency and West Java Province. To find out the superior commodities, a Location Quotient analysis approach was used. There were six types of empon-empon that have been cultivated in Ciamis Regency, including Zingiber officinale, Amomum compactum, Kaepferia galanga, Curcuma longa, Alpinia galanga, and Curcuma zanthorrhiza. Amomum compactum types is considered as a potential commodity to be developed on private forest land because it has a comparative advantage with LQ value>1.

Forest Lands

The National Executive Committee of the Canadian Institute of Forestry was asked by the federal Minister of Fisheries and the Environment to propose and detail specific federal tax incentives for intensified forestry. Estimates and analyses of Canada's present timber supply show that most timber surplus is remote and costly, and emphasize the need for regular and systematic renewal on productive forests in order to maintain the forest industry. Regeneration has not kept pace with depletion, and a backlog of 12% of the productive forest land in Canada now requires treatment. Moreover, serious annual shortfalls in current provincial reforestation programs, are steadily adding to this area. The responsibility for restocking these depleted forest lands rests with those who benefit from productive forests. The federal government is asked to cooperate by changing the Income Tax Act and Regulations to encourage forest operators to invest in current reforestation activities, and by negotiating long-term cost-sharing agreements with provincial governments to attack the backlog.

Abstract Very little effort has been devoted to analyzing the contributions of National Forests to groundwater resources in the US and around the world. In this study, the US Geological Survey's MERAS (Mississippi Embayment Regional Aquifer Study) model was used in the ModelMuse simulating system to estimate more than a century of subsurface hydrologic processes, groundwater budgets, and spatial-temporal groundwater level distributions in three forests in Mississippi, US. The results showed that groundwater recharge and stream leakage are important for groundwater storage in this region. All three forests served as groundwater sinks at times and sources at others, but the volume changes were relatively small. Groundwater levels declined over the simulation period – 1900 to 2014 – beneath all three forests, especially around the DNF (Delta National Forest) where groundwater abstraction is relatively intense. Knowledge gained from long-term hydrologic simulations and water budgets is useful when managing forest land groundwater resources.

In laboratory and small-field experiments inducers of synthetic origin: benzothiadiazole (BTH), salicylic acid, and inducers of biological origin: glycine betaine, extracts prepared from oak bark (Quercus robur L.), Reynoutria sacchaliensis L., curcuma (Curcuma longa L.), ginger (Zingiber officinale Roscoe) were effective against powdery mildew on the winter wheat (cv. Kanzler) susceptible to this disease. All studied inducers slightly effected the synthesis of new proteins (PR-proteins) that were localized in extracellular space. The efficacy of inducers was long-term. The most effective inducer was BTH; its application produced a number of chlorotic blotches on leaves

The paper presents deductive-mathematical analyses regarding short and long-term timber supply of non-industrial private forest owners using several papers of Tahvonen and Tahvonen et al. With the help of an intertemporal dynamic consumer model based on the Faustmann tradition, the effects of utility in situ, non-forest income and credit rationing are investigated: The higher the utility in situ and the non-forest income, the higher is the quantity of the long-term timber supply and the lower the quantity of short-term timber supply. The higher the timber price and the market interest rate, the lower the quantity of the long-term timber supply and the higher the quantity of short-term timber supply. Credit rationing leads to essential modifications of those results. The found results also differ strongly from analyses of the pure case of intertemporal profit maximizers. In the second part inductive-empirical studies concerning timber supply of non-industrial private forest owners are presented as well. Reference is made to two papers with review characteristics in which cases from North America and Scandinavia are analysed. In the third part the results of the two different methods are compared and the relations of these two methods are discussed. Special emphasis is given to the fact that deduction shall not equalize theory and the inductive-empirical method shall not be synonym for reality or practice. Instead inductive-empirical research is also theory. Finally it is explained that the low quantity of short-term timber supply by non-industrial private forest owners is not a result of market failure but of a more complex competition among the different usages of forests that emerged in modern societies.

Abstract This paper analyses the effect of aspects of family background, such as family income and parental education, on the educational attainment of persons born from 1967 to 1972. Family income is measured at different periods of a child’s life to separate long-term versus short-term effects of family income on educational choices.We find that permanent income matters to a certain degree, and that family income when the child is 0-6 years old is an important explanatory variable for educational attainment later in a child’s life. We find that short-term credit constraints have only a small effect on educational attainment. Long-term factors, such as permanent family income and parental education, are much more important for educational attainment than are short-term credit constraints. Public interventions to alleviate the effects of family background should thus also be targeted at a child’s early years, the shaping period for the cognitive and non-cognitive skills important later in life.

Privately Owned

Canada has the third largest area of forest in the world after Russia and Brazil. About 89% is in public ownership; 11%, or 23 million ha, is privately owned. The comparatively small area of forest in private ownership has been largely overlooked. If it were a national forest, it would be the 11th largest in the world, between Japan and Finland, with the 8th largest production of industrial roundwood, between Finland and Germany. Canada's privately owned forest lands produce 19% of our wood supply, some 36 million m3 per year. There are about 425 000 owners with an average of 45 ha each. Their objectives vary greatly. They own a high percentage of the Deciduous, Great Lakes-St. Lawrence and Acadian Forest Regions. These forests are very important environmental, economic and social resources. We should understand their value better and set in place management programs to ensure their health and productivity. Landowner's rights and management objectives must be respected. Key words: private forest land, Canada, wood production, area of forest, management programs

AbstractRapid serial visual presentation (RSVP) of words or pictured scenes provides evidence for a large-capacity conceptual short-term memory (CSTM) that momentarily provides rich associated material from long-term memory, permitting rapid chunking (Potter 1993; 2009; 2012). In perception of scenes as well as language comprehension, we make use of knowledge that briefly exceeds the supposed limits of working memory.

Previous short term toxicological studies of one to two weeks duration have demonstrated that MDL 19,660 (5-(4-chlorophenyl)-2,4-dihydro-2,4-dimethyl-3Hl, 2,4-triazole-3-thione), an antidepressant drug, causes a dose-related thrombocytopenia in dogs. Platelet counts started to decline after two days of dosing with 30 mg/kg/day and continued to decrease to their lowest levels by 5-7 days. The loss in platelets was primarily of the small discoid subpopulation. In vitro studies have also indicated that MDL 19,660: does not spontaneously aggregate canine platelets and has moderate antiaggregating properties by inhibiting ADP-induced aggregation. The objectives of the present investigation of MDL 19,660 were to evaluate ultrastructurally long term effects on platelet internal architecture and changes in subpopulations of platelets and megakaryocytes.Nine male and nine female beagle dogs were divided equally into three groups and were administered orally 0, 15, or 30 mg/kg/day of MDL 19,660 for three months. Compared to a control platelet range of 353,000- 452,000/μl, a doserelated thrombocytopenia reached a maximum severity of an average of 135,000/μl for the 15 mg/kg/day dogs after two weeks and 81,000/μl for the 30 mg/kg/day dogs after one week.

Objectives School-age children with and without parent-reported listening difficulties (LiD) were compared on auditory processing, language, memory, and attention abilities. The objective was to extend what is known so far in the literature about children with LiD by using multiple measures and selective novel measures across the above areas. Design Twenty-six children who were reported by their parents as having LiD and 26 age-matched typically developing children completed clinical tests of auditory processing and multiple measures of language, attention, and memory. All children had normal-range pure-tone hearing thresholds bilaterally. Group differences were examined. Results In addition to significantly poorer speech-perception-in-noise scores, children with LiD had reduced speed and accuracy of word retrieval from long-term memory, poorer short-term memory, sentence recall, and inferencing ability. Statistically significant group differences were of moderate effect size; however, standard test scores of children with LiD were not clinically poor. No statistically significant group differences were observed in attention, working memory capacity, vocabulary, and nonverbal IQ. Conclusions Mild signal-to-noise ratio loss, as reflected by the group mean of children with LiD, supported the children's functional listening problems. In addition, children's relative weakness in select areas of language performance, short-term memory, and long-term memory lexical retrieval speed and accuracy added to previous research on evidence-based areas that need to be evaluated in children with LiD who almost always have heterogenous profiles. Importantly, the functional difficulties faced by children with LiD in relation to their test results indicated, to some extent, that commonly used assessments may not be adequately capturing the children's listening challenges.
