A General Chemistry Course for Prospective Elementary School Teachers

The paper describes a general chemistry course designed for students who are planning to become elementary school teachers. The course has been structured so as to transmit the fun and excitement of experiencing chemistry and uncovering its basic principles by centering on laboratory and other discovery experiences. In addition, the course uses peer led workshops in which the students discuss these experiences. The course is thus a product of a particularly strong collaboration between public schools and college faculties. It is going to become a part of a new four-course sequence that will be required of all students intending to earn elementary education certification at Lehman College

Artificial fish habitats in traditional fisheries of southwest coast of India

Artisanal fishermen of Trivandrum area in South India are showing keen interest to put up artificial reefs to enhance fish production. Non-govenunental organisations working for the welfare of coastal fishermen are giving financial and moral support to these fishermen to deploy more and more artificial reefs. The results of a study made on such reefs are presented in this paper. Granite stones, truck tyres, coconut tree stumps, concrete well rings and concrete slabs are used for the construction of artificial reefs in this area. A gradual increase in the annual fish catch was noticed at Valiathura (Trivandrum) fish landing centre after the establishment of artificial reefs in this area. It rose from 669.0 tormes in the year 1988 to 857.5 tormes in 1989 and to 1442.8 toimes in 1990. Sepia pharaonis was the major component in the catches from these reefs. Carangoides plagiotaenia, C. ntalabarictis, Lethrinus harak, Selar kalla and Selaroides leptolepis were caught only from the artificial reef region at a point of time. Underwater studies revealed the congregation of large shoals of small reef-dwelling fishes and other bottom living animals around the reefs

The sardine fishery of Vizhinjam with suggestions for improvement

The annual landings of sardine fishery at Vizhinjam for the period 1970-77 have been found to fluctuate between 126.6 and 536.7 tonnes with an average at 272.3 tonnes forming 6 5% of the total fish catch of the centre. The fishery extends throughout the year with one major peak during May and two minor peaks during August and October months

ECONOMIC IMPACT OF INTRODUCING ROTATIONS ON LONG ISLAND POTATO FARMS

Potatoes have been grown continuously on many Long Island (New York) fields. Environmental concerns have raised questions about the continued usage of this practice. A farm-level linear programming model was used to investigate the economic impacts of crop rotations which result in reduced potato acreage. Crop rotations (an Integrated Pest Management tactic) reduced total pesticide use, but also reduced returns above variable costs as successively stringent rotation requirements were forced into the solution. The crop rotations which caused the least effect on income were identified.Resource /Energy Economics and Policy,

The influence of emotional reaction on help seeking by victims of school bullying

Research has started to focus on how victims of school bullying cope, but there is still very little understanding if why pupils cope in one way and not another. This paper aimed to examine the effects of gender, school-stage, frequency of victimization and different emotions (anger, vengeance, self-pity, indifference, and helplessness) upon the choice of social support that children report using. Questionnaires were completed by 6282 Maltese schoolchildren aged between 9 and 14 years old. Analyses revealed that specific patterns of emotion and victimization predict whether pupils report using certain sources of social support. Results are discussed in relation to their relevance for possible intervention, future research needs and implications for the theoretical framework used

A Transpersonal Feminist Approach to Family Systems

This paper presents a preliminary description of A Transpersonal Feminist Approach to Family Systems (ATFAFS) as taught at the Institute of Transpersonal Psychology (ITP) between 1995 and 2002. In this approach, students studied the principles of Murray Bowen’s family systems theory with attention to feminist revisions of the theory while simultaneously investigating their own multigenerational family histories. Additionally, students kept a journal, recorded and worked with their dreams, and worked with a chosen creative expressive modality. They may also have worked with other transpersonal modalities. Student narratives, informed by organic inquiry, illustrate aspects of the approach. The paper concludes with a detailed look at students’ perceived benefits and drawbacks of the approach

Ecological observations on a remote montane occurrence of Bedfordia arborescens (Asteraceae), Cape Barren Island, Tasmania

Bedfordia arborescens Hochr. is a tree listed under the Tasmanian Threatened Species Protection Act 1995 and is known in Tasmania only from an outlying population in cloud forest on Mt Munro, Cape Barren Island in the Furneaux Group. While the species is a common component of some rainforest and mixed forest in southeast mainland Australia, the outlying population on Cape Barren Island has apparently been eroded by a high fire frequency over the previous 200 years. The species occupies an ecological zone that is marginal to Atherosperma moschatum Labill.-dominated rainforest. Some stands occur adjacent to grasslands separated by a sharp ecological boundary. Even-aged cohorts represent the population structure on the mountain with no evidence of recent regeneration in or adjacent to any particular stand. A range of different aged cohorts occurs within the forest across the mountain. Mt Munro intercepts cloud moisture, resulting in the development of a cloud forest and a steep precipitation gradient between Mt Munro and the nearby coast. The persistence of B. arborescens on Mt Munro can be attributed partly to the sharp topographical boundaries that have been reinforced by fire due to the burning frequency on the mountain. The vegetation patterning has responded to frequent anthropogenic fires during the past 200 years. Comparisons are made with subalpine grasslands in New Guinea and elsewhere. Future fire management on Cape Barren Island will be critical to the survival of B. arborescens in Tasmania. On the basis of modified IUCN criteria used in Tasmania for listing of threatened species, it is recommended that the status o/B. arborescens be up-listed from rare to vulnerable

Record production of milkfish from ponds developed in sandy beach at Calicut

The milkfish, Chanos chanos, a hardy, euryhaline and fast growing species was cultured to study the production as well as survival rates in the pump-fed, polyethylene film lined ponds developed on sandy beach at Calicut Research Centre of CMFRI from July 1982 to February 1983

The intensive farming of striped Mullet, Mugil cephalus Linnaeus, in the polyethylene film-lined ponds developed on the sea shore at Calicut, Kerala

Significant advances have been made in the mariculture fin fishes in many parts of the world. In India two major cultivable fin fishes, namely, mullets and milk fish, have been used in the traditional culture practices and also in the scientific culture of fin fishes in ponds and pens. Among mullets, the striped mullet Mugil cephalus is a fast growing species and is commonly available on the east and west coasts of India. It is also an important table fish and has a good market both in the coastal and interior regions of our country
