  • Plants are sessile organisms and as such must have mechanisms to deal with both abiotic and biotic stresses to ensure survival. The term “abiotic stress” includes many stresses caused by environmental conditions such as drought, salinity, UV and extreme temperatures. Due to global climate change it is predicted that abiotic stresses will increase in the near future and have substantial impacts on crop yields (Intergovernmental Panel of Climate Change; http://www.ipcc.ch).

  • The discussion of the properties of relative international prices has been closely tied with a discussion on the nature of the pricing decisions by ¯rms. 5 The observed slow pass-through of exchange rate changes to consumer prices and deviations from the law of one price for traded goods are consistent with prices of imported goods that are sticky in the currency of the consumer (local currency pricing). This pricing mechanism, however, dampens the expenditure-switching e®ect of nominal exchange rate movements.

  • The system we are considering needs to support communications for 109 devices. The users using these devices would be interested in peer-to-peer (P2P) style of communication, business- to-business (B2B) interactions or a be part of a system comprising of agents where discoveries are initiated for services from any of these devices. Finally, some of these devices could also be used as part of a computation. The devices are thus part of a complex distributed system. Communication in the system is through events, which are encapsulated within messages.

  • Numerous U.S. REITs and other institutions have invested in real property connected to maquiladoras, retail development and tourism. This trend should persist because Mexico is ripe for continued investment. With respect to retail development, for example, there are fewer than 1,000 malls and shopping centers in Mexico, which has a population of approximately 110 million people. In comparison, there are more than 102,000 malls and shopping centers in the U.S., which has a population of approximately 306 million people.

  • Irish IFs are owned mainly by non-residents, with 26 per cent held by other euro area residents and 68 per cent held by those outside the euro area and just 6 per cent owned by Irish residents. This breakdown reflects a significant move in ownership away from euro area residents to the rest of the world over recent quarters. Similarly most assets owned by Irish resident IFs are domiciled outside the state. When unclassified assets are excluded, just 9.4 per cent of capital is invested in Irish assets, 13.5 per cent invested...

  • Indeed, in the presence of predictability in fund risk loadings and benchmark returns, optimal portfolios consist entirely of actively managed funds even when the possibility of manager skills in stock selection and benchmark timing is ruled out. That is, actively managed funds allow the investor to capitalize on predictability in benchmarks and fund risk loadings in a way that cannot be achieved through long-only index fund positions. We now turn to analyze predictability in manager skills.

  • The IDB began its study thinking the funds had a major impact on em- ployment and income. Our study shows the estimates we made. We collected the data on employment generation in all the funds and ex- penditures per year on average in the funds. The study found that the impact of the funds on employment and income is small. Only the first emergency fund of Bolivia added more than 1 percent per year to the total number of jobs in the economy. Only three funds in the region added more than 0.5 percent to the number of jobs. In other words, the funds did not have a...

  • Hexabromobenzene (HBB) has been used as a flame retardant in polymers, plastics, textiles, wood and paper. Its primary uses have been reported in the plastics, paper and electrical industries (Bruchajzer et al., 2004). U.S. production/import volume was listed as 10,000- 500,000 pounds for 1998, but no information is available beyond that time (U.S. EPA, 2002). In addition to its use as a flame retardant, HBB is a thermal decomposition product of octa- and decaBDEs and hexabromobiphenyl (as cited in Bruchajzer et al., 2004).

  • An important purpose of the Financial Report is to help citizens and policymakers assess whether current fiscal policy is sustainable and, if it is not, the urgency and magnitude of policy reforms necessary to make it sustainable. A sustainable policy is one where the ratio of debt held by the public to GDP (the debt-to-GDP ratio) is stable in the long run. Sustainability concerns only whether long-run revenues and expenditures are in balance; it does not concern fairness or efficiency implications of the reforms necessary to achieve sustainability.

  • Drawing on both Eastern and Western cultural traditions, Isamu Noguchi’s sculptures appear to possess “effortlessness,” a virtue Chinese artists once valued above perfection. Together with the numerous individual sculptures that have emerged from Noguchi’s various studios throughout his long and distinguished career, the artist has been involved in major environ- mental projects, especially since the early 1950s.

  • Although the chapters included in this book are all addressing protein interactions, we try to separate them into two parts according to their objectives. Chapters in part 1 mainly focus on the investigation of some specific protein-protein or protein-nucleic acid interactions, and try to elucidate the mechanism of specific cellular processes. Part 1 provides some insight of why and how to study protein interactions, and illustrates some approaches to modulate protein interactions.

  • In order to attract the best engineers of each generation to one of the most urgent fields of engineering development we must embed understanding not just of the challenges, but the opportunities, within the collective consciousness of the public through the mass media. We must design a career path that is desired by young professionals, accredited by institutions and that will afford recognition and esteem. We must develop university courses that will excite and entice students to address the challenge of creating a low carbon world.

  • Investigations of historic yields are therefore mostly concerned with homo- genous goods such as commodities, for which indices are available. These show that certain real assets can achieve higher yields than investments in equities or bonds. A comparison of the average historic yields on raw materials over the last 10 years (2002 to 2012) shows that investments in commodity futures have achieved double-digit annual returns (see Fig. 15).

  • The plan of the paper is as follows. Section 1 argues that very high government debt/GDP ratios will increase uncertainty about the future path of interest rates. This will reduce the degree of asset substitutability between short-dated and long-dated paper, impairing the effectiveness of changes to the policy rate and making the short-term/long-term mix of government debt sales a more effective instrument of macroeconomic policy (Section 2). But the long-term interest rate on government bonds also has fundamental implications for financial stability (Section 3).

  • Out of the initial sample of 303 restating firms identified from news reports, 216 firms are listed on Standard & Poor’s Compustat database. Out of those, we were able to find a control firm for 185 firms.24 For each of these 185 restating firms, we tried to obtain detailed information on the nature and characteristics of the restatement by reading the relevant SEC filings (Forms 10K, 10K-A, 10Q, and 10Q-A). For 10 firms, despite the initial news reports, we could not find any indication of a restatement in these filings.

  • We define the data placement problem for a P2P system as follows. Assume we are given a set of cooperating nodes connected by a network (typically, but not necessarily, the Internet) that has limited bandwidth on each link. Nodes know about and exchange data with a collection of participating peers, and they may serve any or all of four roles. The first of these is a data origin, which provides original content to the system and is the authoritative source of that data.

  • In the second half of the 1990s economic growth has been favourable stimulated by a clear fall in inte- rest rates. Unemployment was rapidly decreasing and the demand for housing has been growing causing house prices to double since 1991. Production of new housing in urban areas has not increased to the same extent as the population. A shortage of housing and high house prices, especially in the capital city of Oslo and surrounding municipalities, have been the result.

  • On the theoretical side, the available inflationary models may be also evaluated with respect to their “cost”, ie. against what one gets from a given model in relation to what one puts in! Our approach does not introduce new fields, beyond those already present in gravity and supergravity. We also exploit (super)gravity interactions only,ie. do not introduce new interactions, in order to describe inflation. Before going into details, let me address two common prejudices and objections.
