Predicting global invasion risks: a management tool to prevent future introductions

Predicting regions at risk from introductions of non-native species and the subsequent invasions is a fundamental aspect of horizon scanning activities that enable the development of more effective preventative actions and planning of management measures. The Asian cyprinid fish topmouth gudgeon Pseudorasbora parva has proved highly invasive across Europe since its introduction in the 1960s. In addition to direct negative impacts on native fish populations, P. parva has potential for further damage through transmission of an emergent infectious disease, known to cause mortality in other species. To quantify its invasion risk, in regions where it has yet to be introduced, we trained 900 ecological niche models and constructed an Ensemble Model predicting suitability, then integrated a proxy for introduction likelihood. This revealed high potential for P. parva to invade regions well beyond its current invasive range. These included areas in all modelled continents, with several hotspots of climatic suitability and risk of introduction. We believe that these methods are easily adapted for a variety of other invasive species and that such risk maps could be used by policy-makers and managers in hotspots to formulate increased surveillance and early-warning systems that aim to prevent introductions and subsequent invasions

Hidden inequalities amongst the international workforce

This chapter focuses on low status expatriates who have been largely ‘hidden’ from managerial scholarship. They are ‘hidden’ because they are ignored by the migrant literature which looks at people trying to remain in their new society and gain citizenship; and ignored by the expatriation literature which is mainly concerned with high-status ‘top’ talent. These hidden expatriates are typically maids, drivers, security guards, and construction workers - low status and low paid, unable to obtain citizenship, and liable to be sent home, unemployed, at the whim of their employer. If we, as scholars, are to contribute to the betterment of society by elevating the health and well-being of those who live in it, then we must recognise the existence of and address the management issues and concerns of those at the ‘bottom of the pyramid’. We use Organisational Justice theory and draw on examples from Turkey, Singapore and the Middle East to examine the position, the concerns, and the issues of such workers and their often-unequal place in the workforce

Sıvı yönetiminde EVLW ve önemi

Fluid management and optimization is one of the most frequently observed problems in anesthesiology and critical care. An ideal hemodynamic management increases oxygen supply to tissues, improves postoperative outcomes and decreases surgical costs. Extravascular lung water (EVLW) measurement has gained widespread acceptance in the early prediction and management of adverse effects caused by fluid treatment. The fundamental aim of acute circulatory failure treatment is to improve tissue perfusion and oxygenation while avoiding fluid overload. EVLW consists of extravascular interstitial, intracellular, alveolar and lymphatic fluid in the lungs and its normal values are 3-7 ml kg-1. Studies have reported that values above 10 ml kg-1 as a cut-off value points to pulmonary edema. Although the gold standard in EVLW measurement is the gravimetric method, lung ultrasound and transpulmonary thermodilution is more widely utilized since gravimetric measurement can only be performed post-mortem. EVLW measurement is expected to gain importance in the hemodynamic measurement of ALI/ARDS patients and future studies will benefit from focusing on EVLW based fluid therapy. © Copyright Anesthesiology and Reanimation Specialists’ Society.

Structural and Magnetic Properties of -Doped Powders

WOS: 000423378900003Europium-doped powders with the molar concentration of (0.5, 3 and 6 mol%) were successfully prepared at by using molten salt synthesis method. The effect of europium (Eu) molar concentration on the structural and temperature-dependent magnetic properties of powders has been investigated by using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), vibrating sample magnetometer (VSM) and ferromagnetic resonance (FMR) techniques in the temperature range of 10-300 K. XRD results confirm that all the powders have orthorhombic crystal structure. It has been confirmed from VSM and FMR measurements that -doped powders have ferromagnetic behaviour for each molar concentration between 10 and 300 K. XRD and EDX analyses indicate that there is no magnetic impurity in -doped powders, supporting that the ferromagnetic behaviour of the powders arises from ions. The observed ferromagnetism was elucidated with the intrinsic exchange interactions between the magnetic moments associated with the unpaired 4f electrons in ions. The saturation magnetization decreases with increasing molar concentration. The temperature-dependent magnetization behaviour was observed not to agree with Curie-Weiss law because europium obeys Van Vleck paramagnetism. Broad FMR spectra and a g-value higher than 2 were observed from FMR measurements, indicating the ferromagnetic behaviour of the powders. It was found that while the resonance field of FMR spectra decreases, the linewidth increases as a function of molar concentration.Marmara University Research Fund (BAPKO)Marmara University [FEN-E-100713-0319]This work was supported by Marmara University Research Fund (BAPKO) under Project No. (FEN-E-100713-0319)
