The Education Of Culturally And Linguistically Diverse Students

In this study, the researcher has examined and presented the perceptions and attitudes of K-12 school teachers regarding students from culturally and linguistically diverse backgrounds. In addition, these same teachers were asked to evaluate their own professional preparations that might enable them to identify and effectively teach these students. This researcher conducted an in depth study in a Northwest Florida School District (Escambia Co.), and a Nodaway County School District in Missouri.  A proportionate, stratified, random sample of 300 K-12 regular education teachers, special education teachers, school counselors, and therapists was used for the survey. In addition, a case study was conducted of 30 members from each school district.  The findings of these studies, plus previous research and current literature all indicate that these educators were not professionally prepared to identify, understand and work with culturally, and linguistically diverse students.&nbsp

The Effect of Dietary Interventions on Intestinal-associated Metabolites and Immune Parameters

The obesity epidemic has driven the search for dietary interventions for weight reduction. In the current study we determined the role of dietary composition and also timing of feeding on weight loss, with a specific focus on changes in intestinal parameters. Mice were divided into different groups with different feeding protocols. Dietary interventions altered weight gain and body composition and intestinal parameters including small intestinal length and cecum weight. There was no difference in splenic or colonic B and T cell populations, but regulatory T cells numbers were altered with the vegan-based diet

Multicultural Education: Teachers Perceptions And Preparation

In this study, the researcher has explored and described K-12 school teachers’ perceptions of multicultural education and their professional preparation to teach culturally diverse students in a Northwest Florida school district. This was a descriptive study, combining quantitative and qualitative research methods. A proportionate stratified random sample of 150 K-12 teachers was used for the survey and a case study of 15 teachers for the interviews. Correlation coefficients and ANOVA results determined overall significantly low correlations between teachers’ demographics and their perceptions. Previous research and the findings from this study indicate a need for effective preparation in multicultural education for teachers of culturally diverse students

In silico comparative analysis of conserved genes expressed in solanaceous plants under abiotic stresses

The gene expression data was studied in order to analyze genes involved in different abiotic stresses in solanaceous plants. Salt, temperature (heat & cold) and drought are the main abiotic stresses to the plants. Abiotic stress responses are important for sessile organisms like plants because they have to cope with environmental changes to survive. The idea was to analyze those differentially expressed genes, which show common expression in response to different abiotic stress conditions in each plant. Mitogen activated protein kinases (MAPK) are important mediators in signal transmission, connecting the perception of external stimuli to cellular responses. In plants, MAPKs plays a major role in the signaling of abiotic stresses. The expression data were retrieved from gene expression omnibus (GEO) database at NCBI. The set of genes were selected showing up or down regulation in at least two abiotic stresses. These genes were used for searching their involvement in different steps of MAP kinase pathway. Our findings suggest that a common set of genes are the key players in signaling pathway responsible for initiation of cascade of reaction in response to stress. The study will help to understand how the conserved genes are expressing differentially in response to various abiotic stresses. The common genes affecting the MAP kinase pathway might be highly conserved. These genes may be used to study the response of different abiotic stresses in other plant species

Karyomorphology of skin diseases in human population

The aim of the present study is to determine the incidence of chromosomal abnormalities in skin diseases. Patients were analyzed for chromosomal aberrations using peripheral lymphocyte culture. Cytogenetic analysis was carried out in 27 people affected by Vitiligo, Psoriasis, Parthenia. Lymphocytes culture was done and subjected to colcemid, hypotonic treatment, fixation and air drying.  GTG banded chromosomes were identified and counted for abnormalities. One way ANOVA was used to analyze the collected data. Tukey-Kramer Multiple Comparisons Test was used to determine differences between the means. Comparing the groups on the basis of type of chromosomal abnormalities, the differences between the means was found to be non significant (P>0.05) in all the comparisons. However, it was found to be significant for acrocentric association in Vitiligo subjects as compared to the controls. The means for premature centromeric divisions (Parthenia Vs Vitiligo) were also found to be significantly different

A novel and discernible plate assay method for the qualitative screening of bacterial keratinases

174-180Routinely, qualitative screening for keratinolytic activity exhibited by microorganisms is carried out on feather agar medium, containing keratin as the sole source of carbon and nitrogen. Formation of a clear zone of keratin hydrolysis may observed directly on feather agar medium or after flooding the plates with either 5% (w/v) trichloro acetic acid (TCA) or Commassie brilliant blue dye (CBB R-250) for 30 minutes followed by destaining. The main drawback of these methods is that the hydrolyzed area is not sharply discernible which makes judgment very difficult. Hence, an improved, novel and sharply discernible plate assay method is reported herein for the detection of extracellular keratinases production by bacteria and actinomycetes. In this method, feather agar plates are flooded with Gram’s iodine, which formed a bluish black complex with keratin but not with hydrolyzed keratin, giving sharp and distinct zones around the keratinase producing microbial colonies within 3 to 5 minutes. This new method being rapid as well as more effective than other methods in terms of visualization and measurement of zone size could easily be performed for screening a large number of microbial cultures

Impact of Piriformospora indica, Pseudomonas species and Mesorhizobium cicer on growth of chickpea (Cicer arietinum L.)

The present study was conducted to examine synergistic interactions among Piriformospora indica (PI) with potential plant growth promoting rhizobacteria (PGPR) and Mesorhizobium cicer (LGR33, MR) in two chickpea (Cicer arietinum L.) varieties viz. desi PBG1 and kabuli BG1053. Different PGPR species were used viz. native isolates of Pseudomonas argentinensis (LPGPR1), Pseudomonas sp. (LPGPR2) along with national check Pseudomonas sp. (LK884). Compatibility of MR, PI and differentPseudomonas spp. was studied by streak assay method and growth of fungal pellicle in-vitro. Consortium of MR+PI+LPGPR1 (0.605 g dry weight fungal pellicle/100ml nutrient broth) was found as the best compatible treatment. In vivo the synergistic effect of consortia was studied for improving dry weight of roots, nutrient acquisition, colonization and stress tolerance ability in chickpea. Significant improvement in dry weight of root was observed with MR+PI+LPGPR1 (1.316 g plant-1) in comparison to MR alone treatment (0.980 g plant-1) at 90 days after sowing (DAS). Percentage colonization of P.indica improved significantly with consortium MR+PI+LPGPR1 (75.5 and 78.3 %) treatment at 90 DAS. All the treatments significantly improved total soluble sugar content (12.2-26.9 %); amino N content (1.36-1.80 fold) and stress tolerance ability (4-6 fold) over the MR alone treatment. Reducing sugar content significantly improved with MR+PI+LPGPR1 (0.62 and 0.79 mg mL–1) over MR alone (0.42 and 0.58 mg mL–1) treatment in desiPBG1 and kabuli BG1053 chickpea, respectively. The tripartite combination MR+LPGPR1+PI can be explored as potent biofertilizer for improvment in chickpea productivity

Postcolonial Indian Feminism: A Study of Sensible Sensuality: A Collection of Essays on Sexuality, Femininity and Literature

Present paper attempts to study the key features of postcolonial Indian Feminism as represented by Sarojini Sahoo a feminist of international fame in her monumental work Sesnsible Sensuality: A Collection of Essays on Sexuality, Femininity and Literature. Linked with sexual politics of women, this work covers various issues pertaining to women like motherhood, marital practices, socialization of gender, beauty myth, feminine identity and female sexuality. Drawing upon theories of Chandra Talpade Mohanty critiquing monolithic concept of universal womanhood, this research paper underlines the Indian version of feminism as depicted in the text to be studied. The selected work is grounded in Indian socio-cultural context. Sahoo demands equal status for women in every sphere of life. Her bold and candid expression for sexual liberty for women makes her stand apart from the conventional women thinkers and writers. She redefines feminism with Indian perspective dealing with sensitive issues like rape, menopause, abortion, lesibianism from a female perspective

Insecticidal Activity of Ethanolic Extract of Mentha piperata Leaves against Cotton Aphid Aphis gossypii Glover on Okra Crop (Abelmoschus esculentus)ï€

ABSTRACT: Different concentrations of ethanolic extract of Mentha piperata leaves were tested against the adult apterous females and third instar nymphs of aphid Aphis gossypii  infesting okra crop. This aphid is a major limiting factor for the profitable cultivation of okra. The aphicidal activity of Mentha piperata extract was examined on Aphis gossypii with the counted number of third instar nymphs and adult viviparous females. The 2% concentration of the extract has resulted in 100% mortality of nymphs and adults in 72hrs. and 96hrs. time period  respectively. The lower concentration of 1.5% also caused 100% mortality but required more time of 96hrs. At 2% concentration the LT50 value for nymphs and adults were 13.37 and 26.66hrs. The extract of M. piperata can be used as a potent insecticide for the control of cotton aphid A. gossypii infesting okra plants. Key words: Cotton aphid, Aphis gossypii, Insecticidal activity, Mentha piperata, okra crop Pest and Parasite Research laboratory, Post Graduate Dept. of Zoology, Bareilly College, Bareilly- 243005 (U.P.)Please Cite This Article As: Sunita Sharma and Kavita Vidyarthi. 2010.
