This study was conducted to determine the Important Value Indices (IVI) of some plants in the University farm. Eighty plant stands belonging to three families (Musaceae, Caricaceae and Arecaceae) were identified. Their frequency and coverage percentage were measured within the sampling plot. Data obtained were subjected to Chi-square analysis to test for significance at 5% level of significance. The results indicated that the mean richness of Caricaceae, Arecaceae and Musaceae species in the study area were 3, 2 and 6, respectively. The highest (p<0.05) Floral Value Index of 90.52 was recorded in plantain group while the least value (22.40) was recoreded in coconut. The relative density ranged from 7.5 to 45 for the genus Cocos l. and Musa l. The highest Relative Frequency (46.03 %) was recorded for Musa l. and the least in Cocos l respectively. The Important Value Indices ranged between 20 and 152 which indicated that Igbariam had a very rich Agricultural soil for Economic plant development particularly for the families of Musaceae. The Musaceae showed the maximum IVI, hence the most important family among the studied plant species in the Agricultural farm plot. Thus, it is concluded that Musaceae, particularly plantain, should be given special consideration in prioritizing species for crop production in the study area.

 This study presents an attitude of female students studying B.Ed. third year towards physical education and sports within Kathmandu valley. Initially, it was hypothesized that there is no significance difference in attitude of physical education and sports among female students of different campuses. From these 6 campuses, 184 female students were randomly selected. A five-point Likert-type scale was applied for data collection from the selected students who studied in B.Ed. third year. Altogether five opinion statements were used for data collection. It was found that all respondents showed positive attitudes towards physical education and sports. In order to test whether there is significant interdependence in score among the respondents in different perspectives. The chi-square test score was applied as statistical test at the 0.05 level of significance. The chi-test under contingency table: independent of opinion among the respondent, if (χ2>α=0.05 in different degree of freedom) and independent if (χ2≤ α=0.05 in different degree of freedom). For the measurement of attitude for physical education and sports,it has enough evidence in the data to accept alternatives hypothesis; there is relation or interdependence of attitude towards physical education and sports among the respondents. Because, the score is very high among the response of respondent. The study suggests that the university teacher must be accountable to construct professional environment.

Quantitative analysis, distributional pattern and species diversity of woody plant species of Lamberi Range of Rajouri Forest division, J&K, has been carried out by laying 50 quadrats (10m X 10m size) for trees and 100 quadrats (5m X 5m size) for shrubs. Various phytosociological parameters like frequency, density, abundance, importance value index IVI and diversity indices for trees and shrubs has been used to reveal the plant community structure of the area. The abundance to frequency ratio (A/F) for different species was determined to assess the distribution pattern of the species (regular <0.025, random 0.025-0.05 and contagious >0.05) which indicated the contagious distribution for all the species. Survey of the area revealed presence of 63 woody plant species from the study area comprising of 43 trees and 20 shrubs. Pinus roxburghii (IVI 49.7, Abundance 81.1) and Carissa opaca (IVI 81.12 abundance 7.05) have been recorded as the dominant tree and shrub, respectively, of the area. The computation of diversity indices showed that species richness and evenness i.e Shannon- Weiner’s, Margalef’s and Menhinick’s remained high for trees and low for shrubs. Simpson’s index of dominance was also high for trees. Species which needs priorities for conservation and protection and also required to be monitored have also been highlighted.

A survey of 501 alumni with disabilities who attended the University of Illinois during the forty-year period from 1948 to 1988 indicated gender is a major factor in the career choices and the occupational outcomes of university graduates. Chi-square analysis revealed significant relationships between gender and marital status (p < .05), gender and choice of major (p < .01), gender and occupational category (p<.01), gender and parttime or fulltime employment (p < .01), and gender and salary level (p < .01). There was no significant relationship between gender and disability type or gender and employment/unemployment. On the basis of this survey of college alumni, one could conclude gender has a more significant impact on career choice and career development than do the physical or sensory disabilities of college students.

Abstract A multilaboratory study was conducted to compare the VIDAS® LIS immunoassay with the standard cultural methods for the detection of Listeria in foods using an enrichment modification of AOAC Official Method 999.06. The modified enrichment protocol was implemented to harmonize the VIDAS LIS assay with the VIDAS LMO2 assay. Five food types—brie cheese, vanilla ice cream, frozen green beans, frozen raw tilapia fish, and cooked roast beef—at 3 inoculation levels, were analyzed by each method. A total of 15 laboratories representing government and industry participated. In this study, 1206 test portions were tested, of which 1170 were used in the statistical analysis. There were 433 positive by the VIDAS LIS assay and 396 positive by the standard culture methods. A Chi-square analysis of each of the 5 food types, at the 3 inoculation levels tested, was performed. The resulting average Chi square analysis, 0.42, indicated that, overall, there are no statistical differences between the VIDAS LIS assay and the standard methods at the 5% level of significance.

Although thousands of adolescents each year experience the death of a significant person, there is little evidence that the schools have taken on the responsibility of providing grief counseling services. This study investigated the grief counseling services in the middle schools and high schools in the State of Mississippi. The schools were identified by surveying the counselors, employed by those schools, who held membership in the Mississippi School Guidance Counselors Association. Four hundred and thirteen surveys were mailed and two hundred and thirty-three of those returned were usable. Four hypotheses were tested using a chi-square analysis at p < 0.05 level of significance. It was reported by the counselors that 42 percent of the schools did have grief counseling services available to the students; that within that 42 percent stating grief counseling was available, 67 percent reported that grief counseling services were implemented as a result of a sudden death to a member of the school community; that of the reported 42 percent of the schools which had grief counseling available, 81 percent reported it to be an ongoing service; and that of the 42 percent which reported their schools provided grief counseling, 68 percent reported the guidance counselor provided the service. These findings and the findings of other studies reviewed and reported indicate that there is a real need for school administrators to provide or make available grief counseling services for students in the middle schools and high schools in the State of Mississippi.

In healthy societies, physical education and sport activities carry important roles in raising individuals. Previous scientific researches point out that physical activity is very important in the development process of the children. Therefore, children need to be supported in joining planned and systematic physical education and sport activities in both family and school life, beginning at very young ages. Every possibility should be offered to the children for performing sport activities healthily in the habitat while also taking precautions.The purpose of the study is to identify the expectations of the middle-school students and the problems they encounter when attending sport activities in their family and school lives. The data was collected through a survey developed by the researchers. A descriptive method with the aim of revealing the current situation was used in the study. The population of this study consisted of 2500 students, studying in the 5th, 6th, 7th and 8th grades of the middle-school. Two middle schools from the schools within the Sakarya province were selected through a random selection method. The survey was applied to a total amount of 400 volunteer students that were selected as the sample group and studied in these schools. The SPSS 15.0 for Windows software was used for the data analysis. Frequency analysis was used in order to determine the quantity and percentage distributions of the demographic information of the participants. On the other hand, chi-square analysis was used for the comparison of the problems and expectations related to family and school life in regards to the demographic variables. The level of significance in the chi-square analysis was specified as p<0,05.As a result of the study, in relation to the family and school life, the male students were found to have more problems and expectations regarding the participation in physical education and sport activities, when compared to female students. In addition to this, the students who participated in physical education and sport activities regularly seemed to have bigger expectations and more problems with their families.The problems and expectations of participating students regarding the family and school life were identified and suggestions for possible solutions were presented. The study is hoped to be beneficial for the field.

Abstract Background: The Quercus leucotrichophora is a keystone species in maintaining the biodiversity of several other species and provides ecosystem service to the people residing around the forest. The present study is to investigate the community characteristic and coexistence of four medicinally important plants species viz. Boenninghausenia albiflora (Hk.) Reichb. ExMeissn. Hedychium spicatum (Ham. Ex Smith), Origanum vulgare (Linn.) and Rubia manjith (Linn.) in Quercus leucotrichophora forest in different canopies at three different sites i.e. Hanumangarh, Kailakhan and Pines in the Central Himalaya.Results: In the present study, a total of 81 herbaceous species encountered in the sample, out of which 41 species showed Importance Value Index (IVI) ≥ 5. About 50% species were common in different sites whereas about 54 % species were common in different canopies. There was variation in species richness among the sites (52-67 species), whereas, amongst the canopies, species richness was higher in open canopy and least in close canopy. The co-existence between the selected four species showed a frequency distribution <60% indicating their presence as rare, seldom or often. Amongst the sites, Boenninghausenia albiflora and Origanum vulgare showed its dominance in Pines, Hedychium spicatum at Kailakhan and Rubia manjith at Hanumangarh site. The coexistence between Origanum vulgare and other three species viz. Boenninghausenia albiflora, Rubia manjith and Hedychium spicatum showed negative values, while Boenninghausenia albiflora and two other species viz. Rubia manjith, Hedychium spicatum and Rubia manjith & Hedychium spicatum showed positive coefficient of association. The chi-square in both the cases indicated the values are non-significant resulting not a strong coexistence in the Oak forest, therefore their occurrence together in the community might be by chance. Conclusion: The growth of species in different habitat and association of medicinal plants is important in identifying the suitable habitat and canopy toward future multiplication of the different species in the Himalayan region. The finding of the present study would be also helpful to develop the structure and adequate strategy & plan for conservation and management of habitats, species and communities for their sustainable utilization in different part of the world.
