abstract this paper discusses several commonly used models for strategic marketing¹ including market environmental analysis methods (i.e. swot and pest analysis) and strategic marketing tools and techniques (i.e. boston matrix and shell directional policy matrix)and shows how these models may help a firm to achieve its strategic goals. at first, the main reason for doing this research is de...
this study investigated the effect of prior knowledge on the listening comprehension performance of fl learners. twenty students, male and female, drawn from the two intact groups of the senior and junior english language and literature majors were chosen as the participants of this study . the two groups were then randomly assigned into the experimental and control group. the experimental gr...
the purpose of this study was to find the relationship between critical thinking and self-regulation with reading comprehension of iranian female elementary language learners. the present study is a correlational one having a descriptive design. two questionnaires, critical thinking questionnaire and self-regulation questionnaire which were valid and reliable questionnaires and four reading com...
Geographic information systems provide a high level of functionality for spatial analyses but are not yet able to provide extended functionality needed to create a truly "scientific GIS". Functionality that is lacking include time series analyses, calculation of the volume of the overlap between two volumes or calculation of the intersection of a vector path with a volume. Other functions inclu...
the main purpose of the present study was to investigate the relationship between listening proficiency and metacognitive listening strategies awareness among low, mid, and highly self-regulated students. three hundred and seventy one efl students participated in this study (all grade 3 and 4 high-school students who were studying in khansar in academic year 1391-92). to gather the data, three ...
Onsite wastewater treatment systems (OWTS), or septic systems, can be a significant source of nitrates in groundwater and surface water. The adverse effects that nitrates have on human and environmental health have given rise to the need to estimate the actual or potential level of nitrate contamination. With the goal of reducing data collection and preparation costs, and decreasing the time re...
With the aim of exploring the usefulness of spatial analysis in the formulation of a strategy for schistosomiasis japonica control in different environmental settings, a population-based database was established in Dangtu county, China. This database, containing the human prevalence of schistosomiasis at the village level from 2001 to 2004, was analyzed by directional trend analysis supported w...
The US Forest Service adopted the National Hierarchical Framework of Ecological Units in 1993 with the ecological landtype (ELT) and ecological landtype phase (ELTP) forming the lowest levels of the hierarchy. This study examines the potential of computer mapping ELTPs for the Hoosier National Forest (HNF) located in southern Indiana. ELTPs were sampled in 2001–2003 within four units of the HNF...
We investigate farmers’ decision to engage in organic production. Our objective is to identify the key factors that promote or hinder the update of organic farming. In particular, we focus on neighborhood factors and the spatial allocation of organic land parcels. A rich spatial panel data of all agricultural parcels is compiled and the information on land use, soil quality, biodiversity, local...
When researchers are interested in multiple geographic datasets over similar geographic areas, it is oftentimes necessary to mosaic the digital images. The process becomes increasingly difficult as the images vary in projection, spatial resolution, and data representation. We first present a framework to describe this mosaicking process in a formal setting. We resolve the issues of varying proj...
