Feeding management of dairy cattle affect grassland dynamics in an alpine pasture

The effect of different supplementary feeding rates for grazing cattle on high-altitude pastures dynamics was evaluated. A field experiment was carried out during three years in a subalpine pasture area of the Eastern Alps. The investigated pasture area was 40?ha, located between 1820 and 2230?m?a.s.l. Two paddocks were chosen in the experiment and two herds of 12 cattle each were kept in the two enclosures for 5 weeks. For the first herd (HS), the supplementary feeding rate was 4.8?kg?OM?head^?1 per day, while for the second herd (LS), the rate was 1.6?kg?OM?head^?1 per day. The amount of herbage consumed by each cattle was determined using the n-alkane technique. To monitor the pasture vegetation dynamics, eight metal exclusion cages were placed in each paddock to determine herbage growth, utilization rates, vegetation composition and animal grazing selectivity. Grazing behaviour of dairy cattle, in terms of herbage intake and species selection was affected by the different feeding rates. Cattle grazing Paddock HS consumed 1.9?kg?OM?day^?1 of herbage less than Paddock LS. In the LS paddock, cattle grazed higher phytomass rates. When the animals were fed by higher concentrate rates, a more selective grazing seemed to significantly increase the pasture necromass component. The lower grazing selectivity favoured the development of species as Nardus stricta and Deschampsia caespitosa, which are well known for their low palatability. Distinct vegetation dynamic patterns were observed, with a reduction of hair grass and an increase of legumes in the Paddock LS.     

The Curse of Being Landlocked: Institutions Rather than Trade

This article revisits the long‐term economic effects of being landlocked. The conventional wisdom, which also prevails in policy circles, is that landlockedness hurts development by reducing trade. Gravity models of bilateral trade seem to confirm this view. However, there is no evidence in cross‐country data of a systematic relationship between landlockedness and country's trade to GDP ratio. Drawing on this stylised fact, the paper explores the possibility that landlockedness might affect GDP independently from its effect on trade. Theoretical considerations suggest that institutional quality could be a relevant transmission mechanism. The estimation of a system of three equations confirms that landlockedness has a negative effect on GDP and that this negative effect is transmitted through institutions rather than trade. Moreover, after controlling for the transmission via institutions and trade, landlockedness has a further negative effect on GDP. These findings call for a review of the policy approach to the development of landlocked countries.     

ISA 570: Italian Auditors’ and Academics’ Perceptions of the Going Concern Opinion

This study aims to identify which of the indicators used to assess whether an entity may not be able to continue as a going concern are regarded by Italian partners in auditing firms and Italian accounting and finance academics as being the most important. The indicators and ratios are those pursuant to auditing standard ISA 570 Going Concern, the literature and professional practice. ISA 570 does not suggest a hierarchy of these indicators, because they are only examples of events or conditions that, individually or collectively, may cast significant doubt on the entity's ability to continue as a going concern (GC), nor does it suggest specific ratios. To this end, an online survey was administered to partners in auditing firms and to the university faculty of Accounting and Finance. The paper contributes to enriching previous literature by providing insights into how Italian auditors and Italian financial reporting scholars prioritise GC indicators suggested by ISA 570. The results have the potential to help auditors and directors focus on the most relevant indicators in a GC assessment.     

The Gendered Nature of Poverty in the EU: Individualized versus Collective Poverty Measures

Due to the adoption of the household as a unit of analysis, researchers have failed to identify accurate measures of women's income poverty. This study proposes an individualized measure of European poverty to highlight gender differences in the economic crisis. Employing data from the European Union Statistics on Income and Living Conditions (EU-SILC) for the period 2007–12, it compares the household-based at-risk-of-poverty rate (ARPR) and the individualized financial dependency rate (FDR). The study shows that the gender gap in poverty in Europe is considerably higher when computed through FDR. Indeed, since the ARPR constitutes a proxy of the household's average conditions, it levels down gender inequalities within the household and also variations in individuals’ incomes over time. Only more detailed data collection on intrahousehold resource sharing will possibly allow the development of more precise and realistic indicators of women's and men's risks of poverty and financial dependency.     

SEMIPARAMETRIC VECTOR MEM

Financial time series are often non‐negative‐valued (volumes, trades, durations, realized volatility, daily range) and exhibit clustering. When joint dynamics is of interest, the vector multiplicative error model (vMEM; the element‐by‐element product of a vector of conditionally autoregressive scale factors and a multivariate i.i.d. innovation process) is a suitable strategy. Its parameters can be estimated by generalized method of moments, bypassing the problem of specifying a multivariate distribution for the errors. Simulated results show the gains in efficiency relative to an equation‐by‐equation approach. A vMEM on several measures of volatility justifies a joint approach revealing full interdependence.

China and Japan: Culture,economics, and geopolitics in the quest for a leading international role

The Western view of China and Japan is often based on a perception that they are both Confucian and, therefore, are more similar than is actually the case. Although both do share some fundamental characteristics of Asian culture, certain unique features of each, particularly at the level of social relationships and cultural landmarks, make them quite different. Analysing what these features are allows us to understand what influence they have on personal choices and on the decisions of leaders on important issues in these countries. The Asian financial crisis of 1997–99 can be taken as a useful acid test for evaluating the different decision‐making capacities of the Chinese and Japanese leaders. Currency devaluation, exchange rate intervention, banking system restructuring, economic reforms, and responses to international pressure were the main areas in which government action took place. Interpreting the decisions made in these areas from a geographical‐cultural perspective provides a solid basis for analysing geopolitical dynamics and the ‘global’ prospects of the two most important nations of the Far East.     

Ageing,cognitive abilities and retirement

We investigate the relationship between ageing, cognitive abilities and retirement using the Survey on Health, Ageing and Retirement in Europe (SHARE), a household panel that offers the possibility of comparing several European countries using nationally representative samples of the population aged 50+. The human capital framework suggests that retirement may cause an increase in cognitive decline, since after retirement individuals lose the market incentive to invest in cognitive repair activities. Our empirical results, based on an instrumental variable strategy to deal with the potential endogeneity of retirement, confirm this key prediction. They also indicate that education plays a fundamental role in explaining heterogeneity in the level of cognitive abilities.
