Actors and Emotion in Performance
Utilising a survey conducted among actors in the USA and UK, this article examines and challenges the historical assumption that textual-based acting in the West is concerned primarily with the [re]creation of emotion. The idea that acting is based on the [re]creation of emotion is supported by a brief exploration of historical notions of acting from ancient Rome to the early twentieth century. Through the use of a questionnaire and interviews, the author uses the words of modern actors along with the writings of their historical counterparts to demonstrate, statistically and anecdotally, that actors do not feel that they are [re]creating emotions but are, in fact, reacting to the given circumstances as the character they are portraying would
Effect of nonmetallic and intermetallic inclusions on crater formation on the surface of TiNi alloys under the electron-beam impact
AbstractThe regularities of surface cratering in commercial and precision TiNi alloys irradiated with a low-energy, high-current electron beam (LEHCEB) in dependence on non-metallic (TiC(O)) or intermetallic (Ti2Ni) inclusions presented in TiNi matrix are studied. The melting threshold of TiNi alloy was found to be achieved in the range of LEHCEBs energy density Es corresponding to 1.3-1.5 J/cm2. The dominant role of non-metallic inclusions [mainly, TiC(O)] in the nucleation of microcraters was found. The processes initiated by pulsed heating/melting near the inclusion/matrix interface were analyzed. It is proposed that the most important factor enabling the liquid-phase dissolution of inclusions and delivery of impurities of C and O [from TiC(O)] and O (from Ti4Ni2Ox) into TiNi melt are eutectic reactions taking place in the Ti-Ni-C and Ti-Ni-O systems near Ti50Ni50 composition
Does strict employment protection discourage job creation? Evidence from Croatia
Employment protection legislation in Croatia is among the most strict in Europe. Firing is difficult and costly, and flexible forms of employment are limited. Is this apparent rigidity reflected-as one would expect based on standard economic theory-in low labor market dynamics? Is job creation low and hiring limited? Is the job security of insiders achieved at the cost of outsiders not being able to enter thelabor market? The author attempts to answer these questions by examining job flows. If the employment protection legislation is binding, then job and worker turnover should be low. He shows that this is indeed the case. Hiring is limited and the average job tenure is very long in Croatia. Job destruction is low, however job creation is still lower. The result is accumulation of unemployment, in large part due to new labor market entrants not being able to find a job. The high degree of job protection also seems to strengthen the bargaining position of insiders and results in relatively high wages. So, wages in Croatia are higher than among its competitors, even after adjusting for productivity. These high labor costs are likely to contribute to limited job creation in existing firms, but also are likely to discourage the entry of-and thus job creation in-new firms. The author presents evidence that firm growth has been indeed limited in Croatia, contributing to the low employment level. The author examines other potential causes of high unemployment in Croatia (the unemployment benefit system, labor taxation, the wage structure, and skill and spatial mismatches). He argues that they do not play a substantial part in accounting for poor labor market outcomes in Croatia. The author concludes that the stringent employment protection legislation is the key labor market institution behind low job creation and high unemployment. Based on this he recommends specific measures aimed at liberalizing the labor market to foster job creation and employment.Labor Management and Relations,Labor Policies,Labor Markets,Environmental Economics&Policies,Trade Finance and Investment,Labor Markets,Labor Management and Relations,Labor Standards,Banks&Banking Reform,Environmental Economics&Policies
The polarization-based collimated beam combiner and the proposed NOVA fringe tracker (NFT) for the VLTI
The Polarization-Based Collimated Beam Combiner efficiently produces pairwise interference between beams from multiple telescopes. An important feature is achieving ”Photometric Symmetry” whereby interference measurements have no first-order sensitivity to wavefront perturbations (or photometric variations following spatial filtering) which otherwise entail visibility measurements with increased error, bias, and nonlinearity in phase determination. Among other proposed applications, this topology has been chosen as the basis for the design of the NOVA Fringe Tracker (NFT), a proposed 4 or 6 telescope second-generation fringe tracker for the VLTI. The NFT takes advantage of the photometric symmetry thus achieved making it capable of tracking on stars resolved beyond the first visibility null, as well as interfering a telescope beam with one which is 20 times brighter, a design goal set by ESO. By not requiring OPD modulation for interferometric detection, the detector exposure time can be increased without performance reduction due to time skew nor is sensitivity reduced by removing optical power for photometric monitoring, and use of two-phase interferometric detection saves one half of the photons being diverted for detection of the other two (mainly) unused quadrature phases. The topology is also proposed for visibility measuring interferometers with configurations proposed for the achievement of balanced quadrature or 3-phase interferometric detection. A laboratory demonstration confirms »100:1 rejection of photometric crosstalk in a fringe tracking configuration where atmospheric OPD fluctuations were simulated using a hair dryer. Tracking with a 30:1 intensity ratio between the incoming beams was performed while rejecting large introduced photometric fluctuations.IST/OpticaApplied Science
Gold coast nearshore nourishments
In 1988 a large nearshore nourishment at Gold Coast, Australia was carried out. InSeptember/October 1988 1.5 million m3 of sand was dumped nearshore between the -6m and -10m depth contour, in the most southern part of the Gold Coast beaches. Following these works, carried out by WestHam Dredging, further nourishment took place from November 1989 until Mar 1990, consisting of the dumping of approximately 3.6 million m of sand on the beach profile, from Kirra to Coolangatta. It is the 1988 nearshore nourishment that is the main subject of this report.Hydraulic EngineeringCivil Engineering and Geoscience

Governance and economic growth
Because protection of property rights cannot be appropriated by any individual, it is widely recognized as being the state's responsibility. Moreover, recent empirical evidence suggests that protection of property rights leads to higher investment levels and faster growth. The extent of property rights protection differs significantly across countries. The author integrates the emergence of property rights within a simple growth framework. Drawing on North (1990), he presents a model where economic performance and enforcement of property rights may reinforce each other.Initial conditions determine the economy's convergence to a high-income or a low-income steady state. Existing empirical evidence offers tentative support for this theory.Judicial System Reform,Labor Policies,Economic Theory&Research,Environmental Economics&Policies,Common Property Resource Development,Economic Theory&Research,Inequality,Common Property Resource Development,Environmental Economics&Policies,Governance Indicators
Landaanwinning IJburg: Erosie van tijdelijke kering Haveneiland A en voorontwerp recreatiestrand van het Strandeiland
In november 1998 is in het IJmeer begonnen met de eerste fase van de aanleg van de eilandengroep genaamd IJburg. IJburg wordt met behulp van zandsuppletie aangelegd. De eilanden gelegen in het IJmeer worden aangelegd ten behoeve van de woningbouw om het te verwachten tekort aan woningen in Amsterdam in de toekomst op te vangen. In deze studie zijn twee onderdelen van de eilandengroep uitgelicht te weten: \u95 De tijdelijke kering van Haveneiland A. \u95 Recreatiestrand van het Strandeiland. Gedurende de aanleg en zettingsperiode van het Haveneiland A zal de tijdelijke zandkering onbeschermd blijven tegen invloeden van water en de wind. Hierdoor is het mogelijk dat transport van zand plaatsvindt. Door het IBA (Ingenieursbureau Amsterdam) is voorgesteld de tijdelijke kering van Haveneiland A aan te leggen met een talud boven water van 1:5 en een onderwaterhelling van 1:1O. Steilere hellingen zijn niet toegestaan uit oogpunt van stabiliteit op afschuiven van de kering. De volgende vraag deed zich in de studie voor: Welke verbreding van het eiland is nodig om er zeker van te zijn dat er na de uitvoeringsfase en zettingsperiode van 400 dagen nog voldoende zand overblijft voor de aanleg van de definitieve randen? Het recreatiestrand van het strandeiland is het enige gedeelte van de eilandengroep dat de gehele levensduur onbeschermd blijft. De vraag die voor het strand beantwoord moest worden was: Wat is de uiteindelijke ligging van het strand? Het evenwichtsprofiel, 'dwarsprofiel na inwerking van golven', van het strand kan benaderd worden door een onderwaterhelling van 1:28 toe te passen. Dit zou dan ook het aan te leggen onderwaterprofiel moeten zijn. Zonder beschermende maatregelen zou er zo'n 2000 m3 per jaar aan zand verdwijnen. De plaatsing van strekdammen is een goede methode om dit tegen te gaan. Door de ligging van de kustlijn over 41 graden tegen de klokrichting in te draaien zijn de langstransporten voor de kust in evenwicht en vindt er geen of nauwelijks erosie van de kustlijn plaats.Hydraulic EngineeringCivil Engineering and Geoscience
