Water Conflict and Water Management in the Middle East
2004
“Water is Life”: this is often forgotten in countries with abundant water ressources. As a ressource it only gains importance once it is in short supply or once its quality declines. In the case of shortage the battle for water becomes inevitable. At the moment we have up to 200 conflicts of border-crossing water systems in the world. The Middle East is considered to be a typical example of this politically significant problem
Fish Health and Fisheries, Implications for Stock Assessment and Management: The Mediterranean Example
2012
Although fish health may influence key population-level processes, particularly those dealing with natural mortality, reproduction and growth, which in turn affect stock productivity, there has been little emphasis on the links between fish health and management of marine fisheries. This paper addresses this gap and illustrates how knowledge of fish health provides insight to marine fisheries biologists, stock assessment modellers and managers. The study demonstrates ways in which the consideration of condition (energy reserves) indicators and parasitism adds to improved stock assessment and fisheries management, also in situations of data shortage when standard methods cannot be applied, a…
Detecting Asset Misappropriation: Forensic Accounting
2021
The main task of the investigation of asset misappropriation is the correct classification of a crime: identification of the fact of misappropriation and determination of the amount of misappropriated assets. Specificity of asset diversity, asset accounting requirements, and a wide range of misappropriation opportunities require specialised knowledge in accounting and economics that investigators often lack. The aim of the study is to increase the knowledge of investigators in forensic accounting in order to increase effectiveness of investigations in detecting asset misappropriation. In this article, the authors, Latvian and Lithuanian accounting experts, talk about typologies of asset mis…
A welcome shortage of breath
2005
The respiratory systems of animals must guarantee an efficient oxygen supply. But it seems that, in some insects, they have evolved to restrict the flow of oxygen too.
Long-term observation of hepatocellular carcinoma recurrence after liver transplantation at a European transplantation centre
2019
BACKGROUND: The recurrence of hepatocellular carcinoma (HCC) is the strongest survival-limiting factor after liver transplantation (LT) in patients with HCC. In the face of donor organ shortage, it is necessary to identify factors associated with HCC recurrence in order to maximize the utility of the available grafts. OBJECTIVE: To study the phenomenon of HCC recurrence after LT at a European transplantation centre over the past 20 years. METHODS: Data from 304 HCC patients who underwent LT were prospectively recorded. Clinical and pathological factors were assessed for their association with recurrence. RESULTS: Fifty-one patients (16.8%) had HCC recurrence after LT. Patients exceeding the…
Scholarly publishing depends on peer reviewers
2018
The peer-review crisis is posing a risk to the scholarly peer-reviewed journal system. Journals have to ask many potential peer reviewers to obtain a minimum acceptable number of peers accepting reviewing a manuscript. Several solutions have been suggested to overcome this shortage. From reimbursing for the job, to eliminating pre-publication reviews, one cannot predict which is more dangerous for the future of scholarly publishing. And, why not acknowledging their contribution to the final version of the article published? PubMed created two categories of contributors: authors [AU] and collaborators [IR]. Why not a third category for the peer-reviewer? published
Crowd Models for Emergency Evacuation: A Review Targeting Human-Centered Sensing
2013
Emergency evacuation of crowds is a fascinating phenomenon that has attracted researchers from various fields. Better understanding of this class of crowd behavior opens up for improving evacuation policies and smarter design of buildings, increasing safety. Recently, a new class of disruptive technology has appeared: Human-centered sensing which allows crowd behavior to be monitored in real-time, and provides the basis for real-time crowd control. The question then becomes: to what degree can previous crowd models incorporate this development, and what areas need further research? In this paper, we provide a survey that describes some widely used crowd models and discuss their advantages a…
Buffy coat-derived platelets cryopreserved using a new method: Results from in vitro studies
2018
Abstract Cryopreservation for the long-term storage of platelets (PLTs) is a useful method to overcome the limits of platelet shortage. This is an in vitro prospective study to evaluate the count, viability, and function of buffy coat-derived pooled platelet concentrates (BC-PLTs), treated with dimethyl sulphoxide (DMSO) and cryopreserved (CRY BC-PLTs) at −80 °C with a modified Valeri method. PLTs were stored in 6% DMSO with a patented kit. Overall, 49 BC-PLTs from 245 healthy volunteer donors were prepared, cryopreserved, and analysed before and after 3, 6, and 9 months of storage. In flow cytometry, a statistically significant reduction in CD 42b (92.7 ± 4.29% at T0 vs. 23.6 ± 27.5% at T3…
La evaluación de la sexualidad de las personas con discapacidad intelectual: construcción y descripción de una entrevista semiestructurada
2020
Si bien las personas con discapacidad intelectual experimentan la misma necesidad de intimidad que el resto, una serie de barreras sociales impiden la expresión de su sexualidad alentando a que se les perciba como seres asexuales. Por ello, durante mucho tiempo las voces de las personas con discapacidad no han sido escuchadas, lo que conlleva que actualmente exista una escasez de herramientas de evaluación para explorar los diferentes aspectos de la sexualidad de este colectivo teniendo en cuenta sus limitaciones en lectoescritura y comprensión. El objetivo de este estudio es la elaboración de una entrevista semiestructurada fiable y válida que contemple las características de las personas …
Trend Following with Momentum Versus Moving Average: A Tale of Differences
2018
Despite the ever-growing interest in trend following and a series of publications in academic journals, there is still a great shortage of theoretical results on the properties of trend following rules. Our paper fills this gap by comparing and contrasting the two most popular trend following rules, the Momentum (MOM) and Moving Average (MA) rules, from a theoretical perspective. Our approach is based on the return-based formulation of trading rules and modelling the price trends by an autoregressive return process. We provide theoretical results on the similarity between various trend following rules and the forecast accuracy of trading rules. Our results show that the similarity between t…
