Th is study focused on the implementation of environmental management (EM) in the Caribbean accommodations sector based on diff usion of innovations theory. More specifi cally, it examined the status of EM and the diff erences between adopters and non-adopters in terms of hotel characteristics, attitudes to the natural environment, familiarity, and the constraints to implementation. Th is study...

Despite these diffi culties, the need to think about the future of social-ecological systems cannot be avoided. Th e defi nition of sustainability includes the notion of non-decreasing wealth: sustainable policies meet the needs of the present without undermining future generations’ ability to meet their needs (Arrow et al. 2004). Inevitably, environmental actions aff ect future generations as ...

We review the recent developments of the SUSY quantum Hall effect [hep-th/0409230, hep-th/0411137, hep-th/0503162, hep-th/0606007, arXiv:0705.4527]. We introduce a SUSY formulation of the quantum Hall effects on supermanifolds. On each of supersphere and superplane, we investigate SUSY Landau problem and explicitly construct SUSY extensions of the Laughlin wavefunction and topological excitatio...

Chlorops distinguenda Frey is transferred to the genus Chloropsina Becker in accordance with the structure of male genitalia. Thus, Chloropsina distinguenda (Frey) is a new combination. A new species Chloropsina rohaceki sp. n. is described from Sweden and mountains of Slovakia. Some species of the genus Thaumatomyia Zenker are considered. Based on an examination of types of Th. czernyi Duda an...

BACKGROUND Autism spectrum disorder (ASD) is a group of neurodevelopmental disorders characterized by impairment in social communication/interaction and inflexible/repetitive behavior. Several lines of evidence support genetic factors as a predominant cause of ASD. Among those autism susceptibility genes that have been identified, the PTEN tumor suppressor gene, initially identified as predispo...

We study the spectrum of created particles in two-dimensional black hole geometries for a linear, hermitian scalar field satisfying a Lorentz non-invariant field equation with higher spatial derivative terms that are suppressed by powers of a fundamental momentum scale k0. The preferred frame is the “free-fall frame” of the black hole. This model is a variation of Unruh’s sonic black hole analo...

Let X be a simplicial complex with ground set V . Define its Alexander dual as the simplicial complex X∗ = {σ ⊆ V | V \ σ / ∈ X}. The combinatorial Alexander duality states that the i-th reduced homology group of X is isomorphic to the (|V | − i − 3)-th reduced cohomology group of X∗ (over a given commutative ring R). We give a selfcontained proof from first principles, accessible to the non-ex...

Consider the m-th roots of unity in C, where m > 0 is an integer. We address the following question: For what values of n can one find n such m-th roots of unity (with repetitions allowed) adding up to zero? We prove that the answer is exactly the set of linear combinations with non-negative integer coefficients of the prime factors of m.

OBJECTIVES Non-thyroidal illness syndrome (NTIS) is a form of hypothyroidism that occurs during illness. NTIS is characterized by low thyroid hormones (TH) level in the serum and tissues, with normal serum TSH levels that are considered "inappropriately" normal. The mechanisms responsible for a lack of increase in serum TSH during NTIS are unknown. However, a decreased expression of hypothalami...

Thyroid hormone (TH, T3) is required for the normal function of most tissues, with major effects on O2 consumption and metabolic rate. These are due to transcriptional activation of respiratory genes through the interaction of T3-liganded TH receptors with TH response elements or the activation of intermediate factors, with the consequent higher rates of mitochondrial oxidative phosphorylation ...
