Ethical issues in topical computer vision applications

2017

Computer vision is a research area that contains multiple methods to approach numerous visual problems. In the past decade, it has been rapidly evolving with the introduction of many new technologies and applications that utilize different computer vision techniques. The purpose of this study is to identify the ethical issues that concern recent trending computer vision applications and their tasks. This was done by conducting an integrative literature review and synthesizing various studies that have been conducted on the different applications of computer vision and their ethical issues. The result was a synthesized framework of different ethics themes that relate to the different areas o…

Differences in Chromatic Sensitivity Estimated Using Static and Dynamic Colour Stimuli

2017

Abstract The current study reports on a novel computerised colour vision test employing static and dynamic stimuli. The aim of the study was to assess if static and dynamic stimuli result in comparable chromatic discrimination thresholds when participant’s age is taken into account. Participants (n = 20) were 21 to 77 years old, had normal colour vision and no history of any eye disease. They all participated in two sessions estimating chromatic sensitivity with static and dynamic stimuli, respectively, with six directions in colour space varying either along the red-green (RG) or yellow- blue (YB) directions. We found no significant differences in chromatic thresholds along a tritan axis o…

Bleomycin: Action on growth of oncogenic RNA viruses and on cell transformation

1975

Bleomycin (BLM) inhibits cell proliferation of noninfected chick embryo fibroblasts by blocking their DNA synthesis selectively. Chick embryo fibroblasts have beentransformed by Schmidt-Ruppin D strain of Rous Sarcoma Virus. Transformation has been determined by a focus assay. Foci formation is strongly reduced by BLM. Virus replication is inhibited by BLM in growing and confluent monolayer cells. This result might be explained by the observation that this drug reduces proliferation of growing and of confluent monolayer cells very sensitively. During the first 24 hours after infection the BLM inhibitory effect is more pronounced than in the case of BLM-application during the period 24--48 h…

Protective coloration of European vipers throughout the predation sequence

2020

Antipredator adaptations in the form of animal coloration are common and often multifunctional. European vipers (genus Vipera) have a characteristic dorsal zigzag pattern, which has been shown to serve as a warning signal to potential predators. At the same time, it has been suggested to decrease detection risk, and to cause a motion dazzle or flicker-fusion effect during movement. We tested these hypotheses by asking whether (1) the zigzag pattern decreases detection risk and (2) the detection is dependent on the base coloration (grey or brown) or the snake's posture (coiled, basking form or S-shaped, active form). Additionally, (3) we measured the fleeing speed of adders, Vipera berus, an…

Visual Acuity and Contrast Sensitivity Depending from Keratoconus Apex Position

2017

Abstract Various studies have demonstrated that patients with keratoconus have significant loss of contrast sensitivity while its value varies in different studies. None of these studies has analysed reduced contrast sensitivity depending on the position of apex of corneal conus. Visual acuity and contrast sensitivity were evaluated for patients with keratoconus using the FrACT software. Contrast sensitivity was assessed at the following frequencies: 1, 3, 5, 7, 9, 11, 13, and 15 cycles per degree (cpd). Twenty-four eyes with keratoconus were analysed. Contrast sensitivity was significantly lower for patients with the apex at the centre compared with apex on the periphery both with (p = 0.0…

Constructing knowledge : epistemic practices in three television interview genres

2011

This study analyses epistemic practices in broadcast television interviews, focusing on three different interview genres: celebrity interviews, sports interviews and political interviews. In the analysis I examine the linguistic and interactional practices that are used to construct knowledge in the interviews. These practices include mobilization of different types of knowledge, use of assessments to invite first-hand knowledge, negotiation of epistemic stances while disaligning with the question, and use of assessments for claiming or contesting epistemic rights to authority and expertise. The study comprises four articles and a summary. Article I focuses on celebrity interviews and analy…

System dozoru elektronicznego w Polsce – praktyka stosowania

2019

Napisania niniejszego artykułu podjęto się z uwagi na istniejący od czasu wprowadzenia ustawy o dozorze elektronicznym (2007 r.) problem stosowania kary pozbawienia wolności w systemie dozoru elektronicznego w praktyce. W Polsce z systemu dozoru elektronicznego korzysta obecnie jedynie około 30% całkowitej przewidzianej do odbywania kary w ten sposób liczby skazanych. Pomimo funkcjonowania od 12 lat ustawa wciąż wymaga poprawek. Za podstawowe dwa problemy uznaje się dużą liczbę odrzuconych wniosków o zastosowanie dozoru elektronicznego (w tym również umorzonych postępowań) oraz wnioskowy charakter tego systemu. Do zbadania zjawiska wykorzystano metody i techniki badawcze jakościowe (indywid…

La integración de la Atención a la Dependencia en los Servicios Sociales Municipales del Ayuntamiento de Sagunto

2011

El cuarto Pilar del Bienestar Social es el sistema de Servicios Sociales, la atención a la dependencia debería ser considerada un subsistema del sistema de Servicios Sociales, el catalogo de prestaciones que recoge la Ley de Autonomía Personal y Atención a las Personas en Situación de Dependencia (Ley 39/2006) se corresponde con las prestaciones reconocidas en las leyes de servicios sociales de las diferentes Comunidades Autónomas, todas ellas aprobadas con anterioridad a la Ley 39/2006. La implantación por parte de la Generalitat Valenciana de la Ley de atención a la dependencia puede vulnerar el principio de Autonomía Local recogido en varios marcos normativos. La visión de atención integ…
