TROLLing: Scope and operation of an open repository for linguistic datasets

Poster: TROLLing (opendata.uit.no) is an international archive for open linguistic data and statistical code (e.g. R scripts), launched in 2014 at UiT The Arctic University of Norway. With the increasing demand for archiving and sharing research data, as well as the problem of improper attribution, TROLLing aims to meet researchers’ needs by proposing safe storage of data files, and metadata templates based on international standards. Retrieval, sharing, and reuse of data is further facilitated by TROLLing being part of a global open data network. As regards attribution, the system automatically provides a dataset citation, comprising among other things the author name(s) and a persistent identifier (doi). A version control allows researchers to update their datasets at any time, previously published versions still being available open access. TROLLing is available to all subfields of linguistics, but is limited to structural data. The metadata template, however, allows linking to primary data, stored elsewhere.TROLLing (opendata.uit.no) is an international archive for open linguistic data and statistical code (e.g. R scripts), launched in 2014 at UiT The Arctic University of Norway.

The Impact of Peer Pressure to Disregard Parental Authority on Academic Achievement of Secondary Schools Students

This study investigated the impact of peer pressure to disregard parental authority on academic achievement of secondary school students. Two hypotheses were tested in this study. Relevant literature were consulted to support the study. The variant of research design that was adopted in this study is correlation survey design. Survey design involves obtaining data from a sample (survey) of the population. The study is carried out in Cross River State, Nigeria. Sample size of 400 was used. Multistage sampling procedure was adopted. A sampling technique combining simple and stratified random sampling was adopted for the purpose of this study. Stratification was done based on the educational zones in the state. In each zone, 4 Local government Areas were sampled using the simple random sampling method. In each local government Area, thirty–three (33) persons will be sampled by simple random sampling method. Questionnaire is used as instrument for data collection. Correlation coefficient is used to analyse data for the purpose of the study. Findings of the study include among others that Peer Pressure to overrule parental control/authority does significantly affect academic achievement among secondary school student in Cross River State, Nigeria. Based on the findings of this study, recommendations were made which include that a child should be trained and taught to appreciate parental authority. If necessary, strict disciplinary actions should be used by parents in an effort to carry this out. DOI: 10.7176/JEP/10-35-10 Publication date: December 31st 201

Spatially structured genetic diversity of the Amerindian yam (Dioscorea trifida L.) assessed by SSR and ISSR markers in Southern Brazil

Dioscorea trifida L. (Dioscoreaceae) is among the economically most important cultivated Amerindian yam species, whose origin and domestication are still unresolved issues. in order to estimate the genetic diversity maintained by traditional farmers in Brazil, 53 accessions of D. trifida from 11 municipalities in the states of São Paulo, Santa Catarina, Mato Grosso and Amazonas were characterized on the basis of eight Simple Sequence Repeats (SSR) and 16 Inter Simple Sequence Repeats (ISSR) markers. the level of polymorphism among the accessions was high, 95 % for SSR and 75.8 % for ISSR. the SSR marker showed higher discrimination power among accessions compared to ISSR, with D parameter values of 0.79 and 0.44, respectively. Although SSR and ISSR markers led to dendrograms with different topologies, both separated the accessions into three main groups: I-Ubatuba-SP; II-Iguape-SP and Santa Catarina; and III-Mato Grosso. the accessions from Amazonas State were classified in group II with SSR and in a separate group with ISSR. Bayesian and principal coordinate analyzes conducted with both molecular markers corroborated the classification into three main groups. Higher variation was found within groups in the AMOVA analysis for both markers (66.5 and 60.6 % for ISSR and SSR, respectively), and higher Shannon diversity index was found for group II with SSR. Significant but low correlations were found between genetic and geographic distances (r = 0.08; p = 0.0007 for SSR and r = 0.16; p = 0.0002 for ISSR). Therefore, results from both markers showed a slight spatially structured genetic diversity in D. trifida accessions maintained by small traditional farmers in Brazil.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Univ São Paulo, Luiz de Queiroz Coll Agr, Dept Genet, BR-13400970 São Paulo, BrazilUniversidade Federal de São Paulo, Dept Biol Sci, BR-09972270 São Paulo, BrazilUniv Calif Davis, Dept Plant Sci MS1, Sect Crop & Ecosyst Sci, Davis, CA 95616 USAUniversidade Federal de São Paulo, Dept Biol Sci, BR-09972270 São Paulo, BrazilFAPESP: 2007/04805-2Web of Scienc

CULTIVATION OF OYSTER MUSHROOM (Pleurotus tuber-regium) ON SELECTED ORGANIC WASTES

ABSTRACT Cultivation of OYSTER MUSHROOM (Pleurotus tuber-regium) on selected organic waste was carried out in the Microbiology Laboratory, Faculty of Science of the University of Port Harcourt. The study evaluated the effect of selected organic wastes on the growth and yield of Pleurotus tuber-regium (Fr. Singer). The organic wastes (Dry Substrates which include Maize cob, Cassava peelings, Plantain peelings and water melon pod) were used in the study. Experiments were carried out using Completely Randomized Design (CRD) with 4 treatment and 3 replicates. Maize cob (T 1 ) and Cassava peelings (T 2 ) Supported very abundant mycelial growth and also the development of healthy fruit bodies of the fungus studied. Plantain peelings (T 3 ) and water melon pod (T 4 ) supported abundant and moderate mycelial growth of P. tuberregium respectively but fruit bodies were not developed on them. In all parameters measured fruit bodies produced on T 1 were better than those on T 2 except in dry weight. In terms of average diameter of pileus on T 1 it was 13.0cm while on T 2 it was 10.2cm; average number of healthy fruit bodies formed on T 1 was 20, on T 2 , 15: average height of stipe on T 1 was 7.0cm and on T 2 , 5.1cm: average fresh weight of fruit bodies on T 1 was 87.3g where as it was 85.0g on T 2 but the dry weight of P. tuber-regium was 21.8g on both T 1 and T 2. The Biological efficiency (B.E) of P. tuber-regium produced on T 1 was 8.7% and 8.5% on T 2 .Corn cobs and cassava peelings which are major agro wastes abundantly found in Nigeria, have been found to excellently support the mycelial growth and fruit body formation of pleurotus tuber-regium. P. tuber-regium a Nigerian edible mushroom is therefore recommended to both existing and intending mushroom farmers because of its good growth performance on various substrates
