Exocytotic incorporation of plasmalemmal precursor vesicles (PPVs) into the cell surface is necessary for axonal outgrowth and is known to occur mainly at the nerve growth cone. We have demonstrated recently that plasmalemmal expansion is regulated at the growth cone by IGF-1, but not by BDNF, in a manner that is quasi independent of the neuron's perikaryon. To begin elucidating the signaling pathway by which exocytosis of the plasmalemmal precursor is regulated, we studied activation of the IRS/ ...

We review the literature on Dutch disease, and document that shocks that trigger foreign exchange inflows (such as natural resource booms, surges in foreign aid, remittances, or capital inflows) appreciate the real exchange rate, generate factor reallocation, and reduce manufacturing output and net exports. We also observe that real exchange rate misalignment due to overvaluation and higher volatility of the real exchange rate lower growth. Regarding the effect of undervaluation of the exchange rate ...

Commodity-exporting countries have significantly benefited from the commodity price boom of recent years. At the current juncture, however, uncertain global economic prospects have raised questions about their vulnerability to a sharp fall in commodity prices and the policies that can shield it from such a shock. To address these questions, this paper takes a long term (4 decade) view at emerging markets’ commodity dependence, the history of commodity price busts and the role of policies in mitigating ...

This article develops country-specific vector autoregressive (VAR) models with block exogeneity restrictions to analyze how exogenous factors affect business cycles in the Eastern Caribbean. It finds that external shocks play a key role, explaining more than half of macroeconomic fluctuations in the region. Domestic business cycles are especially vulnerable to changes in climatic conditions, with a natural disaster leading to an immediate and significant fall in output – but the effects do not appear ...

In the last decade, a group of Latin American countries (Bolivia, Paraguay, Peru, and Uruguay) experienced a gradual, yet sustained decline in financial dollarization. This paper documents the stylized facts and uses a standard VAR approach to examine the drivers of both deposit and credit de-dollarization. It finds that the exchange rate appreciation has been a key factor explaining deposit de-dollarization. The introduction of prudential measures to create incentives to internalize the risks of ...

When tested in rectangular arenas, the navigational behavior of the ant Gigantiops destructor can produce results similar to vertebrates. Such results are usually interpreted as supporting the ability of animals to segregate spatial geometry and features. Here, we combine a detailed analysis of ants' paths with panoramic images taken from the ant's perspective that can serve as a basis for developing view-based matching models. The corner choices observed in ants were better predicted by the use ...

We document that (i) although private investment growth in emerging markets has decelerated in recent years, it came down from cyclical highs and remains close to pre-crisis trends; and (ii) investment-to-output ratios generally remain close to or above historical averages.We show that investment is positively related to expect future profitability, cash flows and debt flows, and negatively associated with leverage.Critically, it is also positively related to (country-specific) commodity export prices ...

We study the dynamic response of gross capital flows in emerging market economies to different global financial shocks, using a panel vector-autoregressive (PVAR) approach. Our focus lies primarily on the potentially stabilizing role played by domestic investors in offsetting the response of foreign investors to adverse global shocks. We find that, while foreign investors tend to retrench from emerging markets in response to global risk aversion and monetary policy shocks, foreign asset repatriation ...

Social network analysis is a powerful tool that enables us to describe and quantify relationships between individuals. So far most of the studies rely on the analyses of various network snapshots, but do not capture changes over time. Here we use a stochastic actor-oriented model (SAOM) to test both the structure and the dynamics of relationships of three groups of wild vervet monkeys. We found that triadic closure (i.e. the friend of a friend is a friend) was significant in all three groups while ...

Against the background of political turmoil in the Middle-East, Europe faces an unprecedented surge in asylum applications. In analyzing the economic impact of this inflow, this paper draws from the experience of previous economic migrants and refugees, mindful of the fact that the characteristics of economic migrants can be different from refugees. In the short-run, additional public expenditure will provide a small positive impact on GDP, concentrated in the main destination countries of Germany, ...

A society is a complex system composed of individuals that can be characterized by their own attributes that influence their behaviors. In this study, a specific analytical protocol based on social network analysis was adopted to investigate the influence of four attributes (gender, age, matriline, and hierarchical rank) on affiliative (allogrooming) and agonistic networks in a non-human primate species, Macaca sylvanus, at the park La Forêt des Singes in France. The results show significant differences ...

Abstract Cybergenetics is a novel field of research aiming at remotely pilot cellular processes in real-time with to leverage the biotechnological potential of synthetic biology. Yet, the control of only a small number of genetic circuits has been tested so far. Here we investigate the control of multistable gene regulatory networks, which are ubiquitously found in nature and play critical roles in cell differentiation and decision-making. Using an in silico feedback control loop, we demonstrate ...

Among nonhuman primates, the evolutionary underpinnings of variation in social structure remain debated, with both ancestral relationships and adaptation to current conditions hypothesized to play determining roles. Here we assess whether interspecific variation in higher-order aspects of female macaque (genus: Macaca) dominance and grooming social structure show phylogenetic signals, that is, greater similarity among more closely-related species. We use a social network approach to describe higher- ...

The social relationships that individuals experience at different life stages have a non-negligible influence on their lives, and this is particularly true for group living animals. The long lifespan of many primates makes it likely that these animals have various tactics of social interaction to adapt to complex changes in environmental or physical conditions. The different strategies used in social interaction by individuals at different life stages, and whether the position (central or peripheral) ...

From a cognitive point of view, management and knowledge of social relationships is thought to be very challenging. Because of ecological and demographic constraints, relationships are likely to be prone to variation and hence need constant updating. Social network analysis is a potential tool to quantify the information that needs to be processed. However, despite the growing number of studies on social networks, few have focused on their dynamics and how they evolve across time. Here we present ...

Lactobacillus casei and Lactobacillus rhamnosus proteins P40 and P75 belong to a large family of secreted cell wall proteins that contain a carboxy(C)-terminal CHAP or NlpC/P60 superfamily domains. In addition to their peptidoglycan hydrolases activity, proteins in this family are specific antigens of pathogens, frequently responsible of interactions with the host. L. rhamnosus GG and L. casei BL23 purified P40 and P75 proteins have antiapoptotic activity by inducing the EGF/Akt pathway. The aim ...

The sociality of cattle facilitates the maintenance of herd cohesion and synchronization, making these species the ideal choice for domestication as livestock for humans. However, livestock populations are not self-regulated, and farmers transfer individuals across different groups. Individuals consequently have to adapt to different group compositions during their lives rather than choose their own herd mates, as they would do in the wild. These changes may lead to social instability and stress, ...

Abstract In social networks analysis, two different approaches have predominated in creating null models for hypothesis testing, namely pre‐network and node network permutation approaches. Although the pre‐network permutation approach appears more advantageous, its use has mainly been restricted to data on associations and sampling methods such as ‘group follows’. The pre‐network permutation approach has recently been adapted to data on interactions and the focal sampling method, but its performance ...
