This paper focuses on three “safe haven” assets (gold, oil, and the Swiss Franc) and examines the impact of recent financial crises and some macroeconomic variables on their return co-movements during the last two decades. All financial crises produced significant increases in conditional correlations between these asset returns, thus revealing consistent portfolio shifts from more traditional towards safer financial instruments during turbulent periods. The world equity risk premium stands out as the most relevant macroeconomic variable affecting return co-movements, while economic policy uncertainty indicators also exerted significant effects. Overall, this evidence points out that gold, oil, and the Swiss currency played an important role in global investors’ portfolio allocation choices, and that these assets preserved their essential “safe haven” properties during the period examined.

Clearing of native vegetation is a major threat to biodiversity in Australia. In Queensland, clearing has resulted in extensive ecosystem transformation, especially in the more fertile parts of the landscape. In this paper, we examine Queensland, Australian and some overseas evidence of the impact of clearing and related fragmentation effects on terrestrial biota. The geographic focus is the semi-arid regions, although we recognise that coastal regions have been extensively cleared. The evidence reviewed here suggests that the reduction of remnant vegetation to 30% will result in the loss of 25–35% of vertebrate fauna, with the full impact not realised for another 50–100 years, or even longer. Less mobile, habitat specialists and rare species appear to be particularly at risk. We propose three broad principles for effective biodiversity conservation in Queensland: (i) regional native vegetation retention thresholds of 50%; (ii) regional ecosystem thresholds of 30%; and (iii) landscape design and planning principles that protect large remnants, preferably > 2000 ha, as core habitats. Under these retention thresholds, no further clearing would be permitted in the extensively cleared biogeographic regions such as Brigalow Belt and New England Tablelands. Some elements of the biota, however, will require more detailed knowledge and targeted retention and management to ensure their security. The application of resource sustainability and economic criteria outlined elsewhere in this volume should be applied to ensure that the biogeographic regions in the north and west of Queensland that are largely intact continue to provide extensive wildlife habitat.

Abstract Leishmaniases are a global health problem and in Argentina are considered emerging diseases. The new transmission scenarios of tegumentary leishmaniasis are especially important given that large areas of forest are being transformed into rural and urban systems. The aim of this study was to analyze the impact of the construction of a large public building and a neighborhood on the assemblage of Phlebotominae in a rural area with forest remnants and to correlate the changes observed in the species assemblage with characteristics of the environment. Entomological surveys with light traps were conducted on the construction campus in the northeastern region of Argentina at six sites representing different environmental situations. Structural environmental characteristics and meteorological conditions were recorded and analyzed. At least 16 species of Phlebotominae sand flies were collected, the most prevalent being Nyssomyia whitmani (Antunes & Coutinho), followed by the genus Brumptomyia (França & Parrot) and Migonemyia migonei (França). Our study provides evidence of how the structure of the assemblages and prevalent species respond to anthropogenic disturbances. As the construction progressed, both Ny. whitmani and the genus Brumptomyia were favored. The genus Brumptomyia was favored at sites surrounded by high proportions of forest, within patches of remnant vegetation, and relatively far from anthropogenic disturbances, while Ny. whitmani, the main vector of tegumentary leishmaniasis in the region, increases their abundant at short and intermediate distances from vegetation margins and areas close to anthropogenic disturbances, therefore increasing the risk of human exposure to vectors.

Nowadays, when we still see the impact of COVID not only in the Czech Republic, but all over the world, when the value of money is constantly decreasing due to inflation and negative trends in the economy, people usually try to save their savings where they are confident that they will not lose value. The purpose of the article is to characterize the policy of the Czech National Bank in relation to the real estate market. Research hypothesis. The population of the Czech Republic now perceives housing as a safe haven and protects their savings by buying real estate. That is why, according to practicing economists, the great interest of Czechs in investing in real estate will continue in the coming years. Presentation of the main material. Wealthy people in the Czech Republic are now investing their money in apartments to protect their savings from inflation, which was largely fueled by covid restrictions. Rising inflation and volatility in world currencies is a serious blow to those who keep their savings in cash, so people want to own any asset that has any hope of going up. Originality and practical significance of the research. It has been proven that overheated markets sometimes collapse with dire consequences for a country's economy. And this is the responsibility of the regulators, who must anticipate and prevent such trends in the markets. Conclusions and prospects for further research. The current situation with the pandemic has not affected the real estate market, which is perhaps surprising. The population of the Czech Republic now perceives housing as a safe haven and protects their savings by buying real estate. The main task today of all financial market regulators, not only in the Czech Republic, but all over the world, is and will be the task of preventing a sharp collapse of the formed bubbles, including the real estate market.

Abstract The anti-tax avoidance directive (ATAD) implemented in the EU countries in 2019 has brought, among other things, a common rule for tax-deductibility of exceeding borrowing costs of corporate taxpayers – the interest limitation rule. For interest limitation, the Czech Republic had so far used the so-called safe haven thin capitalisation rule. With the implementation of ATAD, companies need to test not only the thin capitalisation rule but also the new interest limitation rule according to ATAD. This paper aims to review the impact of the new interest limitation rule on the 200 largest Czech companies by their 2017 revenue as recorded in the Albertina database. Results covering the new rules, i.e. following the ATAD implementation, are being compared to the situation before the implementation. Most of the analysed companies seem unaffected by the new interest limitation rule. The analysis also showed that most of the analysed companies do not imply exceeding borrowing costs, either before or following the ATAD implementation.

PurposeThis study is not intended to be a prescriptive blueprint for any nation or region to fight terrorism, but rather it aims to analyze the development of policies supporting terrorism and their impact on regional as well as international relations. It is an examination of relevant facts, which might hopefully benefit policy makers and practitioners who diligently work on reducing or eliminating terrorist activities.Design/methodology/approachIn order to achieve the objectives of the paper and in light of the pool of the available literature and data, the study adopts the system-analysis method in analyzing the impact of policies supporting terrorism and the countermeasures to apply based on the inputs, outputs and conversions associated with the phenomenon of terrorism.FindingsPolicies supporting terrorism differ from a state to another starting from providing safe haven to terrorist groups to providing direct finance and armaments to directly intervening militarily in a targeting country. Or deter such policies. This raised the concerns of many States in the region regarding the domination tendency of Turkey and called for a firm and pragmatic international, regional and Arab stand beyond verbal condemnation to deter Turkey from pursuing such policies.Originality/valueThe importance of the academic study stems from the importance of addressing one of the central issues in the field of regional and international relations, which is the policies some states adopt to support terrorism, not only by financing terrorism but also by incubating terrorism. Most studies on terrorism focus on the concept and situations and not on policies that support terrorism and their impact on regional and international relations and the means of encountering terrorism.

The interactions between land, vegetation, and climate are highly complex and there are few demonstrations of the many potential combinations of treatments which could be used to combat dryland salinity. For this reason, computer simulations are used. This is the first of 2 papers that describe the results of computer modelling of revegetation strategies to reduce land and water salinisation in the western wheatbelt of Western Australia. A distributed parameter, physically based, cellular, 2-layer, mathematical model was used to simulate the effect of a variety of treatments. Modelling predicted that if current land use continues, 40% of the cleared area will become saline. Modelling replacement of the annual pasture with a deep-rooted perennial pasture or pristine native vegetation prevented the onset of salinity, but block or alley treatments always left a significant residual saline area and seepage even at the highest density of revegetation modelled. Combining remnant vegetation in pristine condition, 60-m-spaced tree belts and deep-rooted perennial pasture in mainly the upper mid-slope bays between tree belts reduced saline land to 10% of the cleared area and seepage volume to 30% of the untreated case. The second paper describes the impact of faults on treatment effectiveness.

Purpose – Rankings of the world's cities by a liveability factor have become increasingly significant in the media, among governments and city councils in the promotion of cities, as well as academics interested in understanding the impact of quantifying liveability on urban planning and the relationship of liveability indices and tourism. The paper aims to discuss this issue. Design/methodology/approach – While examining characteristics of liveable cities according to some of the widely reported liveability indices, such as those produced by Mercer, Monocle magazine and the Economic Intelligence Unit (EIU), the authors provide a snapshot of Perth as a liveable city and consider liveability in relation to urban tourism, sustainability and environment. Perth's liveability ranking is discussed in terms of environmental sustainability, noting that for Perth to retain its position as one of the world's most liveable cities, consideration must be given to sustainable planning and environmental practices at policy, organisational and individual levels, placing the long-term liveability of the environment and Perth's flora and fauna at the forefront of urban, and tourism, planning. Findings – The accessibility of nature in Perth and its surrounds, its outdoor recreational opportunities and warm climate are factors that make it unique. Developing and promoting nature-based tourism would further enhance the accessibility of nature for visitors and residents. While Perth's EIU top ten ranking is justified, its major attributes remain unrecognised by the widely used EIU liveable city assessment framework. Research limitations/implications – Moreover, the notion of a liveable city is open to contention due to the subjective nature of various assessment criteria. Liveability indices should include quantifiable environmental factors such as green space, remnant vegetation, biodiversity, air quality and unpolluted water. Originality/value – This paper thus contributes to the discourse on what constitutes a liveable city, the authors emphasise that liveability is significantly related to the presence of green space and natural areas as well as the opportunity to see and interact with wildlife. Perth has such opportunities for it residents and visitors but as yet the aforementioned natural characteristics are not implicit in international measures of liveability.

The objective of this paper is to examine whether terror attacks that took place in the Eurozone in the 21st century had a significant effect on the price of the Euro. Its novelty is twofold: it is the first study that assesses the impact of such events on the price of the Euro and employs a relatively large number of these events. The event-study methodology is used to deduce whether, after a terror event, the value of the Euro declines vs. other major currencies. We found that it does not, since following such an event, the decline was seldom over 0.5%. We also found, however, evidence of some diversion to safe-haven currencies, such as the Swiss Franc. Regression analysis revealed that factors such as the ‘number of attacks’, the ‘type of target’ and the ‘type of attack’, but not the number of casualties, affected the price of the Euro.
