Cirsium candelabrum Griseb. (Asteraceae) u Hrvatskoj - početak invazivnog širenja izvan prirodnog areala?

The natural range of a species Cirsium candelabrum Griseb. (Asteraceae) comprises the territory of the Balkans (Balkan endemic): Bosnia and Herzegovina, Montenegro, Albania, Serbia, Kosovo, Macedonia, Greece, Bulgaria and south-west Romania. Outside of its natural range, C. candelabrum has recently been found in the European part of Turkey, in Slovenia and Croatia. First findings in Croatia were reported from south Croatian region of Dalmatia in 2008 and 2010 by Jasenka Topić. The species was included, based on these findings, in Flora Croatica Database in 2008. In summer 2014, we were looking for the localities of C. candelabrum in Dalmatia, from the hinterland of cities of Split and Makarska to the border area between Croatia and Bosnia and Herzegovina. A large number of new localities (50) was found, mainly on industrial zone of Dugopolje and along the roads leading towards border crossings of settlements of Aržano and Kamensko. The results indicate the spread of this plant in the hinterland of Dalmatia from Bosnia and Herzegovina. The plant grows in ruderal habitats along roads, especially when the natural vegetation has been removed by means of road building or reconstruction. Monitoring can help us to understand whether the latest findings of C. candelabrum on localities outside its natural range is only a temporary phenomenon or is it the beginning of its invasive spread. So far, it occurs only on anthropogenic habitats and shows no tendency to spread on agricultural land or natural habitats and vegetation.Prirodni areal vrste Cirsium candelabrum Griseb. (Asteraceae) obuhvaća područje Balkana (balkanski endem): Bosna i Hercegovina, Crna Gora, Albanija, Srbija, Kosovo, Makedonija, Grčka, Bugarska i jugozapadna Rumunjska. Izvan svog prirodnog areala, nedavno je zabilježena u europskom dijelu Turske, u Sloveniji i u Hrvatskoj. Prve nalaze za Hrvatsku navodi Jasenka Topić, koja biljku 2008. i 2010. pronalazi na nekoliko lokaliteta u srednjoj Dalmaciji. Na temelju tih nalaza vrsta je od 2008. uvrštena u bazu podataka „Flora Hrvatske“. Tijekom ljeta 2014. istraživali smo nalazišta C. candelabrum u srednjoj Dalmaciji, od zaleđa Splita na sjeveru do Makarske na jugu prema granicnom području s Bosnom i Hercegovinom. Pronađen je veliki broj novih nalazišta (50), najviše na području industrijske zone Dugopolje te oko Aržana i Kamenskoga. Rezultati pokazuju da se ova biljka širi u zaleđu srednje Dalmacije, na ruderalnim staništima uz rubove cesta, naročito na mjestima gdje je zbog gradnje i rekonstrukcije cesta odstranjena prirodna vegetacija. Monitoring će pokazati jesu li najnovija nalazišta vrste C. candelabrum izvan prirodnog areala samo privremeni fenomen ili je riječ o početku njezina invazivnog širenja. Za sada dolazi samo na antropogenim staništima i ne pokazuje tendenciju širenja na poljoprivredne površine te prirodna staništa i vegetaciju

IMPLEMENTATION OF MOTION ESTIMATION BASED ON HETEROGENEOUS PARALLEL COMPUTING SYSTEM WITH OPENC

International audienceHeterogeneous computing system increases the performance of parallel computing in many domain of general purpose computing with CPU, GPU and other accelerators. Open Computing Language (OpenCL) is the first open, royaltyfree standard for heterogenous computing on multi hardware platforms. In this paper, we propose a parallel Motion Estimation (ME) algorithm implemented using OpenCL and present several optimization strategies applied in our OpenCL implementation of the motion estimation. In the same time, we implement the proposed algorithm on our heterogeneous computing system which contains one CPU and one GPU, and propose one method to determine the balance to distribute the workload in heterogeneous computing system with OpenCL. According to experiments, our motion estimator with achieves 100 to 150 speed-up compared with its implementation with C code executed by single CPU core and our proposed method obtains obviously enhancement of performance in based on our heterogeneous computing system

An intersection in population control: Welfare reform and indigenous people with a partial capacity to work in the Australian Northern Territory

In Australia, in the last decade, there have been significant policy changes to income support payments for people with a disability and Indigenous people. These policy reforms intersect in the experience of Indigenous people with a partial capacity to work in the Northern Territory who are subject to compulsory income management if classified as long-term welfare payment recipients. This intersection is overlooked in existing research and government policy. In this article, we apply intersectionality and Southern disability theory as frameworks to analyse how Indigenous people with a partial capacity to work (PCW) in the Northern Territory are governed under compulsory income management. Whilst the program is theoretically race and ability neutral, in practice it targets specific categories of people because it fails to address the structural and cultural barriers experienced by Indigenous people with a disability and reinscribes disabling and colonising technologies of population control

Optimal Opportunistic Monetary Policy in A New-Keynesian Model

The present paper compares the performance in terms of second order accurate welfare of opportunistic non-linear Taylor rules and with respect to traditional linear Taylor rules. The macroeconomic model representing the benchmark for the analysis includes capital accumulation (with quadratic costs of adjustment), price rigidities (quadratic approach), along the standard New-Keynesian approach. The model is solved up to second order approximation and welfare is evaluated according to several criteria (conditional to the non-stochastic steady state, unconditional, and according to a linear ad hoc function). The results show that: (i) the opportunistic rule is a Pareto improvement with respect to other monetary policy rules traditionally considered in the literature; (ii) the computation of welfare costs reveals that the burden of adjustment is almost entirely on labor supply fluctuations;(iii) increasing the degree of price rigidities and the degree of competition in the final goods markets, makes the opportunistic rule even more preferable with respect to the alternatives. Business Cycle statistics for the model with opportunistic rule show a large volatility in labor supply, with a limited volatility for the nominal interest rate

Analysing the SML97 Definition: Lexicalisation

The specification of the syntax and semantics for Standard ML have been designed to support the generation of a compiler front end, but actual implementations have required significant modification to the specification. Since the specification was written there have been major advances in the development of language analysis systems that can handle general syntax specifications. We are revisiting the SML specification to consider to what extent, using modern tooling, it can be implemented exactly as originally written. In this short paper we focus on the lexical specification

WOMEN IN LEADERSHIP: HOW A WOMAN’S BACKGROUND AFFECTS HER LEADERSHIP STYLE

Stereotypes and beliefs about women have often kept them from equality with men. What is more striking is that women perpetuate the stereotypes and beliefs as much as men and society as a whole. This literature review focuses on three areas in a woman’s background that influence her ability to lead: a) triggers that propel her into a leadership position, b) the “intersectionalities” or multiple identities and personalities a woman must have to be an effective leader, and c) how the context of where she leads affects her leadership behavior. It also addresses the need for more research to identify barriers and challenges for women leaders, and factors which may bring about cultural change within the United States, leading to an even more influential role for women leaders
