Abstract:

Native desert vegetation in Kuwait has been severely depleted due to both natural and anthropogenic factors and are facing the danger of extinction. Symbiotic rhizospheric microflora influences the growth of plant communities in different ecosystems. The objective of this study is to emphasize the enhancing effect of rhizospheric microbial inoculum on the growth of native desert plants. A shed house experiment was conducted using Nitraria retusa which was selected on the basis of its importance and potential for the revegetation of desert flora. The plant was propagated in three different soil

Inputs from terrestrial habitats to aquatic habitats are important for structuring aquatic communities. Terrestrial producer diversity in the tropics may decline due to anthropogenic causes. I investigated how tree diversity affects aquatic communities. We used leaves from three timber-producing species (Dalbergia retusa, Pachira quinata, and Tectona grandis) to test the effects of leaf litter species composition and richness on invertebrate aquatic communities in Gamboa, Panama. We quantified macroinvertbrate species richness and abundances, leaf litter mass loss, and dissolved carbon to

Abstract:

The purpose of this research has been to study contemporary Mormon migration in the United States. The underlying assumption of the research was that Utah Mormons are culturally and normatively different from Mormons living elsewhere. Research was carried out in two stages. The first stage was a description of migration streams between four designated regions, i.e. Utah, states adjacent to Utah, other Western states, and the remaining Other states. This stage also determined the proportion of return migration in each stream. It provides initial evidence of the cultural pull of Utah for Mormons

Abstract:

Purpose: Whether researchers have an obligation to disclose genetic incidental findings (GIFs) to research participants has been widely debated but has lacked empirical data. This is the first extensive national examination of IRB professionals’ understanding, experience, and beliefs surrounding GIFs in the context of genomic sequencing. Methods: We conducted a cross-sectional online survey of 796 individuals sampled from Public Responsibility in Medicine and Research (PRIM&R) about background and experience with GIFs and ethical reasoning supporting or diminishing an obligation to disclose.

Markowitz introduced the concept of modelling the risk associated with a given security as the variance of the expected return and showed how under certain conditions an investors portfolio can be managed by balancing the expected return of the portfolio and its variance.

There are number of assumptions governing the residuals of the Sharpe index model, one being that the error terms of the stocks are uncorrelated. The

Abstract:

This thesis attempts to investigate the cross-sectional predictive power of return asymmetry, skewness and tail risk. It mainly consists of three empirical chapters on the relation between predictive patterns of the return distribution and expected stock returns. In the first empirical chapter, I adopt a measure of asymmetry, originally proposed by Patil et al. (2012), which can be employed to characterise the shape of the entire distribution of asset returns instead of skewness. Empirical evidence on the relation between asset returns and the skewness of the return distribution is mixed. As s

As expected the return in the private sector is higher than in the public sector. Females have a higher return than males, but there are no differences between East and West Germans.

The expected yield to maturity on a defaultable obligation equals the nominal yield less expected default losses. However, in a mark-to-market world, one doesn't have the luxury of reporting one's performance on the basis of yield to maturity. Total return is calculated for an arbitrary holding period, and must reflect any mark-to-market gains or losses as at the close of the period-gains or losses that can be triggered by the bond's upgrade or downgrade. Thus to estimate expected total return, one must estimate not only expected default losses, but also the impact on capital price of expec

Cystic fibrosis (CF) is caused by defective function of CF Transmembrane Conductance Regulator (CFTR), an epithelial ion channel that facilitates chloride secretion. Previous research has identified impaired dark adaptation (DA) in CF, which has been attributed to concomitant vitamin A deficiency or CF-related diabetes (CFRD). However, CFTR has been localised to the retinal pigment epithelium (RPE) and it is proposed that abnormal DA could be a primary manifestation of CF. DA is similarly impaired in individuals with type 1 and 2 diabetes and is thought to be caused by retinal hypoxia as oxyge

Corporate water risk is a function of resource dependence, which exposes firms to uncertainty. Firms rationally seek to reduce this risk, and this shapes their disclosure strategies. However, the consequence is that corporate water risk disclosure is becoming increasingly unfit for purpose. As current approaches begin to acquire institutional legitimacy and the path-dependent label of best practice, a status quo is becoming embedded, reinforced through mimetic behaviour. The agency problem that this creates is unchecked; in part because of the legitimacy acquired by the disclosure strategies,

Abstract:

A expressão do receptor de potencial receptor transiente, vanilóide 1 (TRPV1) começa desde estágios pré-sinaptogênicos da retina. O bloqueio farmacológico desse receptor nesse período diminui a apoptose fisiológica, havendo possível envolvimento da sinalização de MAP quinases. Na retina do animal adulto, observamos que a expressão de TRPV1 é amplamente difundida, albergando neurônios, células endoteliais e células da microglia. A ativação dos receptores TRPV1 é potencialmente citotóxica, e os mecanismos que podem estar envolvidos incluem a liberação de glutamato, a excitotoxicidade e o estress

Abstract:

Dans cette thèse, deux aspects asymptotiques des temps de retour et d'entrée sont étudiés: les taux locaux de temps de retour, et les lois limites des k-ièmes temps de retour et d'entrée. Dans le cadre des "shifts" Sturmiens, des formules permettant de calculer les taux locaux de temps de retour sont développées. La classe des lois limites de premier temps d'entrée est décrite explicitement. Nous y prouvons que la classe des lois limites des k-ièmes temps de retour est la même que celle des premiers temps de retour, caractérisée par Y. Lacroix. Enfin, nous y exhibons un lien entre les lois lim

Abstract:

The present study was designed to look at inhibition of return within a schizophrenic population for the first time. Inhibition of return is an attentional phenomenon that has been studied with a number of populations, and has been shown to be present in normal individuals. Based on the disattention hypothesis put forth by Cromwell and colleagues (e.g., Cromwell & Dokecki, 1968), it was hypothesized that patients with schizophrenia would show an impaired inhibition of return. Twenty-eight inpatients with schizophrenia, and 19 normal comparisons were evaluated on a visual inhibition of return t
