In the past, researchers in the field of environmental psychology have explained environmental perceptions primarily through socioeconomic and demographic factors. However, knowledge of and support for protecting specific natural features of the landscape should also be influenced by one’s location, setting, and proximity to such features. This article focuses on residents’familiarity with and ...

In state of the art sentiment analysis, text is analyzed for a single unidimensional sentiment or opinion score. This unidimensional sentiment, however, cannot capture the nuances of emotions: for example, two texts that respectively convey anger and sadness will both have a negative sentiment associated with them, while carrying very different connotations. Thus, we require a tool that allows ...

where A is an unknown p× n matrix of coefficients and E is an unobserved m× n random noise matrix with independent mean zero and variance σ. We want to find an estimate  such that ||Y −XÂ|| is small. If we use standard least square estimation directly to estimate A in (1.1) without adding any constraints, then it is just the same as regressing each response on the predictors separately. In thi...

Larval settlement in the fouling polychaete Hydroides elegans Haswell (1883) is mediated by natural biofilms, a complex consortium of marine bacteria, benthic diatoms, protozoa, fungi and adsorbed organic matter. Currently, the inductive effect of natural biofilms on larval settlement is attributed to the bacterial component. In this paper, we present results of an investigation of the diatom c...

The amount of sialic acid on the surface of the neutrophil influences its ability to interact with other cells. Neutrophil activation with various stimuli mobilizes intracellular sialidase to the plasma membrane where it cleaves sialic acid from cell surfaces. Since enhanced neutrophil adherence, spreading, deformability and motility each are associated with surface desialylation and critical t...

In this project, an object detection algorithm is implemented. The algorithm is capable of locating keyboards in images. Main component of the algorithm is based on GMM models which can be applied to objects other than keyboards as well, while parts of the algorithm is heuristics based on the characteristics of the keyboard object. The algorithm achieved 80% detection rate for this task.

Recent research on the impact of economics on mental and physical health has raised fundamental questions about structural elements in the macro-economy and their role in creating stress; This paper reviews and integratoes these sometimes conflicting fiddings into a cohesive mod4. Structural elements of our current economic 6sYstem are identified as possible major stres4ers: (1) instability in ...
