Model Approach

The study investigated the relationship among some environmental factors and research attitude of post-graduate students in Nigeria using a path model approach. The researchers were poised at filling the gap in the type of multivariate statistical tools that have hitherto been used in comparing these variables by authors in the research area. One research question was formulated to guide the study. Survey research design was adopted for the study. The study area, which was south-south Nigeria, is one of the geo-political zones in the country with six federal universities. The population of the study was made up of 1,299 post graduate students of education faculties in the six universities. A sample of 520 students (40% of the population) was selected for the study through stratified random sampling method. The study instrument was a questionnaire titled Environmental and Attitude variables Questionnaire (EAVQ) prepared by the researchers. Result of the study showed that 14 out of 15 pathways in the hypothesized model for the relationship between environmental variables and research attitudewere significant and meaningful, withfive direct and nine indirect pathways. Based on the finding, the study recommends an improvement in those environmental factors to bring about corresponding improvement in research attitude. The study suggests that a study of the relationship between other environmental variables not included in this study on graduate students‟ research attitude in federal universities in south-south Nigeria should be carried out by future researchers. Such research can be extended to cover more geo-political zones in the country.

Significant Factors

The relationship between the diatom taxa preserved in surface lake sediments and environmental variables in Dongping Lake was explored using multivariate statistical methods. The statistical analysis showed that the lake was eutrophicated in all seasons. Transparency, chlorophyll a (Chla) and total phosphorus (TP) were the dominant environmental factors in spring and summer, and NH4+-N and chemical oxygen demand (COD) were the dominant environmental factors in autumn and winter. Sixteen genera and 43 species of diatom were found in the surface sediments, and the dominant diatom genera were Aulacoseira, Ulnaria, Cyclotella, Navicula and Fragilaria. A redundancy analysis (RDA) and Monte Carlo permutation 20 test revealed that COD, pH, TP, conductivity and transparency were significant factors influencing diatom assemblage change, meaning that the distribution of the diatom assemblages were mostly influenced by nutrient composition, light intensity and ion concentrations.

The Relationship

The present paper explores some possible links between linguistics and social science, departing from an example of textual analysis originating in research in progress. Particular attention is paid to the characteristics of historical textual analysis and to the relationship between social phenomena and the concepts employed by social scientists. It is argued that the presence of common theoretical problems and shared methodologies provides an interesting starting point for future interdisciplinary research and for up-to-date teaching of post-graduate students.

AbstractAkdeniz and Akbuk lagoons are part of a shallow coastal ecosystem of great aesthetic and ecological importance, located in Muğla Province in the southern Aegean region of Turkey. In the present study, four expeditions to collect ostracods from these lagoons were conducted in May, July, October, and November of 2008. Benthic samples were obtained monthly and several environmental factors were recorded simultaneously in situ. The ecological preferences of the ostracods were monitored, and qualitative and quantitative samples were collected from three sites in Akdeniz lagoon and two sites in Akbuk lagoon. Three ostracod taxa (Cyprideis torosa, Loxoconcha elliptica and Cytherois fischeri) were identified from the Akdeniz lagoon sampling sites and one species (Cyprideis torosa) from the Akbuk lagoon sampling sites. We present and analyze the dominance and distribution of ostracod assemblages and their relationships to environmental factors: temperature, dissolved oxygen, percentage oxygen saturation, pH, redox potential, salinity, and electrical conductivity) using classification and ordination techniques. Canonical correspondence analysis (CCA) is used to characterize the relationship between ostracods and the environmental variables. Approximately 82% of the correlation between the community composition and environmental variables was explained by the first axis of the CCA ordination for the Akdeniz lagoon. The study revealed that the distribution and population density of ostracod species depends on the physicochemical properties of the environment. The reason for this is that Cyprideis torosa and Loxoconcha elliptica are euryhaline species.

En Guayaquil existe el dengue y tiene una población expuesta de forma endémico – epidémica, pero hay escasos estudios sobre la tendencia histórica de los factores que influyen en el comportamiento del dengue. El objetivo de este trabajo es relacionar los factores ambientales y el cambio climático en el comportamiento del Dengue en la ciudad de Guayaquil, durante el período 2010-2014. Se aplicó una investigación no experimental, tipo longitudinal de tendencia. Analizándose el comportamiento de dengue con la pluviosidad, temperatura, humedad y vientos por semanas epidemiológicas. Los resultados de más casos fueron en los años 2010, 2012 y 2014; existiendo variabilidad en su comportamiento. Las variables ambientales mostraron que la pluviosidad tiene escasa relación en la presencia de casos, hallazgos de humedad por encima del 70% con temperatura altas y escasos vientos provocan condiciones para incremento en la transmisión de la enfermedad, pero existen períodos epidemiológicos donde su transmisión disminuye y puede estar relacionado a las temperaturas promedios bajas, humedad relativa y presencia de vientos. A su vez, es de relevancia observar la relación que tiene el aumento de la temperatura superficial del mar con el incremento de casos de Dengue como se observa en los años de más casos.In Guayaquil there is dengue and it has an exposed population in an endemic – epidemic way, but there is little research on the historical trend of the factors that influence the behavior of dengue. The objective of this work is to relate environmental factors and climate change in the behavior of Dengue in Guayaquil city during the period 2010-2014. A Non - experimental research of a longitudinal type of trend was applied, analyzing the behavior of dengue with rainfall, temperature, humidity and winds per epidemiological weeks. The results with more cases were in the years 2010, 2012 and 2014; Showing variability in their behavior. The environmental variables showed that the rainfall has little relation in the presence of cases, humidity findings above 70% with high temperatures and few winds cause conditions to increase the transmission of the disease, but there are epidemiological periods where the transmission decreases and may be related to low average temperatures, relative humidity and presence of winds. At the same time, it is relevant to observe the relationship between the increase in sea surface temperature and the increase in Dengue cases as observed in the years of more cases

Our objectives were to offer insight into the characteristics of the physical environment in the River Danube in Serbia; and to show the relationship between selected environmental factors and the composition and abundance of macrophyte species. The macrophyte survey method followed the European Standard EN 14184, applying Kohler?s five-level descriptive scale. Principal component analysis was carried out to examine the variation in aquatic vegetation, and to analyze the effect of environmental variables on the aquatic vegetation, redundancy analysis was used. To build a simpler model with fewer explanatory variables, yet sufficiently explaining species variability, forward selection of environmental variables was done. Our results confirmed that physical environmental factors significantly influence the establishment and structure of macrophyte vegetation, with the level of hydrological connectivity to the main river channel being the most important, followed by the transparency of the water column, sediment texture and water-flow velocity. In order to inspect the individual relation between best-fitted plant species and each of selected environmental variables, Spearman?s rank correlation coefficients were calculated. We have distinguished plant species with preferences to specific combinations of analyzed factors. Our results provide a background for future, more specific studies on the macrophyte/habitat relationship.

Background. The primary aim of the study reported here was to determine the effectiveness of utilizing local spatial variations in environmental data to uncover the statistical relationships between West Nile Virus (WNV) risk and environmental factors. Because least squares regression methods do not account for spatial autocorrelation and non-stationarity of the type of spatial data analyzed for studies that explore the relationship between WNV and environmental determinants, we hypothesized that a geographically weighted regression model would help us better understand how environmental factors are related to WNV risk patterns without the confounding effects of spatial non-stationarity. Methods. We examined commonly mapped environmental factors using both ordinary least squares regression (LSR) and geographically weighted regression (GWR). Both types of models were applied to examine the relationship between WNV-infected dead bird counts and various environmental factors for those locations. The goal was to determine which approach yielded a better predictive model. Results. LSR efforts lead to identifying three environmental variables that were statistically significantly related to WNV infected dead birds (adjusted R2=0.61): stream density, road density, and land surface temperature. GWR efforts increased the explanatory value of these three environmental variables with better spatial precision (adjusted R2 = 0.71). Conclusions. The spatial granularity resulting from the geographically weighted approach provides a better understanding of how environmental spatial heterogeneity is related to WNV risk as implied by WNV infected dead birds, which should allow improved planning of public health management strategies.

Purpose In developing countries, numerous small- and medium-sized enterprises (SMEs) must innovate because of their scarce resources. This study aims to address the ambidextrous innovation (radical and incremental) associated with firm performance on the SMEs and investigate the moderating effect of environmental factors on the relationship between technological innovation and firm performance. Design/methodology/approach The authors formulate a path model with the variables to investigate the impacts of the two different innovation strategies and their joint effects on firm performance. Meanwhile, they hypothesized that external environmental factors – market dynamism, labour availability, business cost and competitive hostility – moderate the association of radical and incremental innovations with firm performance. The validity of the proposed model was evaluated using a structural equation modelling approach. Confirmatory factor analysis was used to evaluate the convergent validity of the constructs. Findings The authors find that positive association between radical innovation and firm performance; it shows that the radical innovation strategies are positively related to firm performance in SMEs. They also find that the relationship between radical innovation and firm performance has moderated by environmental factors. Second, they find that the incremental innovation strategies have a negative impact to firm performance, and the relationship between incremental innovation and firm performance has no moderated by environmental factors. Practical implications This paper suggests that the managers of SMEs must involve in technological innovation, and offer fourth main implications above. In particular, the authors forewarn SMEs’ managers of the necessity of generating that the relationship between radical innovation and firm performance has moderated by environmental factors, there are approaches fourth items around. Originality/value This study highlights the crucial importance of the mediating role of environmental dynamism when examining the relationship between ambidexterity (radical and incremental innovations) with firm performance; firms can perceive environmental factors and develop technological innovation strategies to enhance business performance.
