The predatory behavior and distribution on unsprayed apple leaves of Zetzellia mali (Ewing) was studied to determine its role as a predator Panonychus ulmi (Koch) Aculus schlechtendali (Nal.).

Feeding rate and egg deposition of the predatory mite Amblyseius fallacis (Garman) was studied in response to density 3 different stages prey Tetranyehus urticae (Koch). Predation depended on up a maximum. The form curve type prey. When stage, there linear relationship between number attacked/predator density, 40 per leaf. adult ♂, by predators maximum However, contrast egg-stage prey, as ♂ further increased so attack predator. As ♀ predator attacked eggs deposited rather than bigger, active...

Recent work has supported that there is a connection between the level of domestic debt and sovereign default on external debt. We examine potential linkages in case study Venezuela from 1984 to 2013. This unique example encompasses multiple financial crises, cycles liberalization policy reversals, alternative exchange rate arrangements. experience reveals nexus among debt, repression, vulnerability.

Venezuela is at a breaking point. The political, economic, financial, social and humanitarian crisis that has gripped the country intensifying. This unsustainable situation raises several urgent questions: Which path will embattled OPEC take out of current turmoil? What type political transition lies ahead? short-term long-term impact have on its ailing oil industry, economy bond debt? would be best most effective prescription for economic recovery under new governance regime? To discuss...

Women in Jordan are excluded from labor market opportunities at among the highest rates world. Previous efforts to explain this outcome have focused on specific, isolated aspects of problem and not exploited available datasets test across causal explanations. We develop a comprehensive framework analyze drivers low female employment systematically their validity, using micro-level data Employment Unemployment Surveys (2008-2018) Jordanian Labor Market Panel Survey (2010-2016). find that...

In the 1980s, concept of sustainable economic development emerged to try deal with complex and pervasive aspects environmental problem. However, an ecological perspective sustainability requires taking a holistic approach that uses ecosphere as frame reference. This paper describes anthroposystem model philosophically views notion in terms human-ecological system functioning within some considerations on its implications.

In the decade 1999-2009, Jordan experienced an impressive growth acceleration, tripling its exports and increasing income per capita by 38%. Since then, a number of external shocks that include Global Financial Crisis (2008-2009), Arab Spring (2011), Syrian Civil War emergence Islamic State (2014) have affected in significant ways thrown economy out balance. Jordan’s debt-to-GDP ratio has ballooned from 55% (2009) to 94% (2018). The continued grow amidst massive fiscal adjustment balance...

Population counts of Zetzellia mali (Ewing) and its prey, Aculus schlechtendali (Nalepa), Panonychus ulmi (Koch), Tetranychus urticae Koch on ‘Delicious’ apple trees were studied to determine what factor(s) regulates predator-prey oscillations. Four interrelated factors considered: leaf nutrients, soil moisture, conditioning, growth the leaves. It was observed that prey populations initially increased when added new Soon thereafter, predator, Z. , numerical response. The combined effect...

This report aims to summarize the main findings of project as gathered by three baseline documents, and frame them within a coherent set policy recommendations that can help Panama maintain their growth momentum in time make it more inclusive. Three elements stand out cornerstones our proposal: attracting retaining qualified human capital; maximizing diffusion know-how knowledge spillovers, leveraging on public-private dialog tackle coordination problems are hindering economic activity...

Jordan faces a number of pressing economic challenges: low growth, high unemployment, rising debt levels, and continued vulnerability to regional shocks. After decade fast the economy decelerated with Global Financial Crisis 2008-09. From then onwards, various external shocks have thrown its out balance prolonged slowdown for over now. Conflicts in neighboring countries led reduced demand from key export markets cut off important trade routes. Foreign direct investment, which averaged 12.7%...
