In 2007 Tunisia’s first Islamic radio channel, Radio Zitouna, was launched. The year before, in 2006, a public expression of Islam by the population culminated when Ben Ali and his regime cracked down on women wearing the Islamic veil in public. Same year the regime caught an Islamist group planning an attack on strategic places and the president and therefore described by the regime as terrorists. With a point of departure in the theories presented by studies of the Arab authoritarian regimes it would be obvious to explain the launch of Radio Zitouna as a regime response to a threat against one of its power strongholds, Islam. However, this article widens the perspective of Radio Zitouna and includes other aspects than the relation between the radio station and the regime. Bases on analysis of a number of programmes broadcast from 2007 to 2009 and interviews with the staff at the radio station in 2009 and 2010 the article presents other contexts which do not only link to the current events in Tunisia but rather relates to a broader historical and political context.

Regime analysis has focused on issues of market failure, the resolution of which depends upon knowledge and institution building. Global communications regimes, however, have been concerned either with issues of pure coordination or with coordination problems with distributional consequences. Outcomes have been decided by the underlying distribution of national power. In those areas where power was asymmetrically distributed and there was no agreement on basic principles and norms—radio broadcasting and remote sensing—no regime was formed. In those areas where distributional issues could not be unilaterally resolved—allocation of the radio spectrum and telecommunications—regimes were created, although both principles and rules changed with alterations in national power capabilities.

The paper proposes a study of broadcasting in one of the most tightly isolated regimes of the communist Eastern Bloc, beyond the paradigms of radio as a pure propaganda medium and of radio history as pure institutional history. Instead of a macro-history from above, this contribution proposes an ethnographically grounded micro-perspective alongside the lines of ?audience studies?, informed by ?oral history? methods. It proposes focusing on the social effects of radio listening and, in a broader perspective, on how radio broadcasting was embedded into larger modernization agendas of the regime of Enver Hoxha.

Abstract We present a highly complete sample of broad-line (Type 1) QSOs out to z ∼ 3 selected by their mid-infrared colors, a method that is minimally affected by dust reddening. We remove host-galaxy emission from the spectra and fit for excess reddening in the residual QSOs, resulting in a Gaussian distribution of colors for unreddened (blue) QSOs, with a tail extending toward heavily reddened (red) QSOs, defined as having E(B − V) > 0.25. This radio-independent selection method enables us to compare red and blue QSO radio properties in both the FIRST (1.4 GHz) and VLASS (2–4 GHz) surveys. Consistent with recent results from optically selected QSOs from SDSS, we find that red QSOs have a significantly higher detection fraction and a higher fraction of compact radio morphologies at both frequencies. We employ radio stacking to investigate the median radio properties of the QSOs including those that are undetected in FIRST and VLASS, finding that red QSOs have significantly brighter radio emission and steeper radio spectral slopes compared with blue QSOs. Finally, we find that the incidence of red QSOs is strongly luminosity dependent, where red QSOs make up >40% of all QSOs at the highest luminosities. Overall, red QSOs comprise ∼40% of higher luminosity QSOs, dropping to only a few percent at lower luminosities. Furthermore, red QSOs make up a larger percentage of the radio-detected QSO population. We argue that dusty AGN-driven winds are responsible for both the obscuration as well as excess radio emission seen in red QSOs.

The extended radio structures or lobes found in edge-brightened radio galaxies represent interactions with the ambient medium over the source lifetimes. Their study probes the temporal evolution in the radio sources and the properties of the ambient medium encountered at different locations. Previous studies (Leahy & Williams, 1984; Leahy et al., 1989) involved radio galaxies with sizes ≃ 400 kpc, and revealed radio morphologies with a variety of off-axis distortions that could be interpreted as due to different ways in which the lobes interact with the galactic halos. Such studies are lacking for radio galaxies having Megaparsec sizes, which extend to distances well beyond the observed galactic halos and are suspected of evolving in a different regime (Baldwin, 1982). Towards learning the evolution of radio galaxies in this size regime, we have carried out a study of a complete sample of Mpc-size radio galaxies; details are presented in Subrahmanyan, Saripalli & Hunstead (to appear in MNRAS, 1996).

AbstractThis study explores whether and how exposure to mass media affects regime support in competitive authoritarian regimes. Using geographical and temporal variation in newspaper circulation and radio signal strength in South Korea under Park Chung Hee's competitive authoritarian rule (1961–1972), we find that greater exposure to media was correlated with more opposition to the authoritarian incumbent, but only when the government's control of the media was weaker. When state control of the media was stronger, the correlation between media exposure and regime support disappeared. Through a content analysis of newspaper articles, we also demonstrate that the regime's tighter media control is indeed associated with pro-regime bias in news coverage. These findings from the South Korean case suggest that the liberalizing effect of mass media in competitive authoritarian regimes is conditional on the extent of government control over the media.

The discovery of the first binary pulsar in 1974 has opened up a completely new field of experimental gravity. In numerous important ways, pulsars have taken precision gravity tests quantitatively and qualitatively beyond the weak-field slow-motion regime of the Solar System. Apart from the first verification of the existence of gravitational waves, binary pulsars for the first time gave us the possibility to study the dynamics of strongly self-gravitating bodies with high precision. To date there are several radio pulsars known which can be utilized for precision tests of gravity. Depending on their orbital properties and the nature of their companion, these pulsars probe various different predictions of general relativity and its alternatives in the mildly relativistic strong-field regime. In many aspects, pulsar tests are complementary to other present and upcoming gravity experiments, like gravitational-wave observatories or the Event Horizon Telescope. This review gives an introduction to gravity tests with radio pulsars and its theoretical foundations, highlights some of the most important results, and gives a brief outlook into the future of this important field of experimental gravity.

Nous presentons un nouvel outil destine a atteindre la condensation de bose-einstein par refroidissement evaporatif d'atomes alcalins confines dans un potentiel magnetique. Notre approche repose sur l'utilisation de materiaux ferromagnetiques pour generer le potentiel de piegeage. Elle nous permet d'obtenir un confinement efficace avec une puissance electrique faible (100 w). Apres une experience preliminaire qui nous a permis de valider l'utilisation d'un electroaimant a coeur de fer pur pour le piegeage magnetique d'atomes neutres, nous avons developpe un electroaimant de seconde generation que nous avons utilise pour etudier le refroidissement evaporatif d'un gaz de rubidium 87. Ce dispositif a pour particularite de pieger les atomes dans un champ magnetique eleve, de l'ordre de 100 gauss. A cause de la valeur elevee du champ magnetique, l'effet zeeman quadratique n'est plus negligeable et les transitions radio-frequence entre sous-niveaux zeeman adjacents ne sont plus resonnantes au meme point. Cette propriete a des consequences dramatiques sur le refroidissement evaporatif dans l'etat f = 2 et conduit a une interruption de l'evaporation. Une experience d'evaporation a frequence fixe nous a permis de mettre en evidence l'influence de cet effet. Nous avons egalement observe que le refroidissement d'un gaz piege dans f = m = 2 ne permet pas de diminuer la temperature en dessous de 50 k. En revanche, le processus d'evaporation n'est pas affecte pour l'etat hyperfin inferieur f = 1 et nous avons pu atteindre la condensation de bose-einstein en refroidissant le gaz en dessous de 150 nk.

Rural electrification has been a long-standing objective in many developing countries. For decades, the assumption and practice has been to build centralised generating capacity and transmit the electricity over national grids. More recently, interest has grown in using PV (photovoltaic) technology as a solution to the problem of rural electrification. A private household market for PV has been developing in Kenya since 1984 and now has more than 200,000 systems installed, sold through this private market. Consequently, it is widely hailed as a success story among developing countries. Until recently, Tanzania had almost no household PV market, despite interest from a number of actors, including some of those who have been involved in enabling the rapid growth of the market in Kenya. However, sales of PV began to grow quite rapidly from the early 2000s and the trend appears to be gaining pace, with an estimated 285 kWp sold in 2007, having risen by 57% in one year. At the time of the research, there were two large donor-funded PV projects underway in the country. The research attempts to explain the dynamics of the two PV niches over the past 25 years using strategic niche management as its theoretical framework. It finds that the Kenyan niche has benefited more from donor support than is usually acknowledged. The thesis also makes theoretical and methodological contributions. It offers a way to connect first and second-order learning to expectations and visions concepts; dimensions expectations and visions; and presents a tool for systematic investigation of socio-technical trajectory developments. The thesis also suggests a number of ways in which the strategic niche management framework could be enhanced. These include stronger theorising about learning, and the incorporation of power, politics and risk into the theory.

In practice, a communication system works with finite blocklength codes because of the delay constraints and the information-theoretic bounds which are proposed for finite blocklength systems can be exploited to determine the performance of a designed system. In this thesis, achievable rates for given average error probabilities are considered for finite blocklength systems. Although classical bounds can be used to upper bound the error probability, these bounds require the optimization of auxiliary variables. In this work, a bound which is called the dependence testing (DT) bound that is free of any auxiliary variables is exploited. The DT bound is evaluated by introducing a normal approximation to the information density. Simulations carried out both for the Gaussian and discrete input alphabets show the proposed approximation enables very good prediction of the achievable rates. The proposed approximation is also used to calculate the average error probability for block fading channels. Simulations performed for Rayleigh block fading channels demonstrate that the total blocklength of the system in addition to the number of fading blocks should be accounted for especially when the number of fading blocks is large. A power allocation problem in block fading channels when the channel state information is available to the transmitting side is investigated in the final part of this work. The DT bound is optimized for a given channel state vector by allocating different power levels to each fading block by exploiting short-term power allocation. A simple power allocation algorithm is proposed which comes out with very similar results compared with the analytically computed values.

The Minerva Project was a distance learning project of the Brazilian Ministry of Education (MEC) which used radio as its main medium. It began in the second half of 1970, remaining until the early 1990s and it was intended to offer supplementary training for adults. The program, half an hour in length, was aired on a mandatory basis, from Monday to Friday on a national radio chain. The program was complemented by a magazine sent by the post office to the radiopostos - places where students, along with a monitor, had access to the radio receiver. The project was implemented by the Brazilian government during the military regime; however, during this research, a public collection of documents of Paraná State was discovered, which suggested a "Communist infiltration” in the radio program produced by MEC. Thus, the interest became to understand the Minerva Project, its origins, organization and forms of educational activities, seeking to capture the political-ideological struggle undertaken in that context. The primary sources used in the analysis (the State of Paraná's public collection documents) came from literature by Pinto (2013; 2014), Ferraretto (2010; 2014; 2016), Aggarwal (2007). In addition, an interview with one of the coordinators of the Project, Professor Marlene Blois (2015), contributed to the analysis. In conclusion, due to the censorship of the military regime in place at the time, and the content of the radio program being pre-recorded, there was no possibility of an ideological transmission.
O Projeto Minerva foi um programa de ensino a distância do Ministério da Educação que utilizou como ferramenta principal o rádio. Teve seu início no segundo semestre de 1970, o qual permaneceu até o começo dos anos 1990 e almejava oferecer formação supletiva para adultos, tendo duração de meia hora; era veiculado, em caráter obrigatório, de 2ª a 6ª feira, em cadeia nacional de rádio. Contava, ainda, com o apoio de fascículos enviados pelos Correios para os radiopostos – lugares onde os alunos, juntamente com um monitor, tinham acesso ao aparelho receptor. O Projeto foi implantado pelo governo brasileiro durante o Regime Militar, no entanto, nesta pesquisa, atenta-se para documentos do acervo público do Estado do Paraná, liberados em 2013, os quais direcionaram para uma possibilidade de “infiltração de comunistas no programa da rádio MEC, Projeto Minerva da Educação”. Assim, o interesse voltou-se para, primeiro, compreender o Projeto Minerva, sua origem, organização e forma de atuação educativa, buscando captar a luta política-ideológica empreendida naquele contexto. Para tal, a pesquisa bibliográfica utilizou-se de autores como Pinto (2013; 2014), Ferraretto (2010; 2014; 2016), Aggarwal (2007), além de entrevista com uma das coordenadoras do Projeto, a Professora Marlene Blois (2015), e análise de fontes primárias (documentos do acervo público do Estado do Paraná). Diante dessas considerações, concluiu-se que a própria censura do Regime e o fato de o conteúdo dos programas de rádio serem pré-gravados impossibilitaria qualquer possibilidade de transmissão de ideologia que fosse contrária ao estabelecido pelos militares. O encerramento do projeto coincidiu com o fim do Regime Militar

Low density plasmas are found throughout the known universe. Therefore, accurate diagnostic methods have implications for our understanding of a variety of topics, ranging from star formation to the semi conductor industry. Low density plasmas are ubiquitous in the material processing industry. However, measurements of the electron temperature and density, two of the most fundamental plasma properties, are not straightforward. In the laboratory, we create a low density, radio frequency, helium plasma with a bi-Maxwellian electron distribution, similar to those found in the semiconductor processing industry. We use optical emission spectroscopy to perform a non invasive measurement of the plasma conditions. We compare this to measurements obtained using a Langmuir probe, a commonly used invasive diagnostic. The optical emission spectroscopy is found to be insensitive to electron density but good agreement is found between the two techniques for values of the temperature of the hot electron component of the bi-Maxwellian. Plasmas created with high-intensity lasers are able to recreate conditions similar to those found during astrophysical events. This development has led to these condi- tions being explored in laboratories around the world. An experiment was performed at the Rutherford Appleton Laboratory in Didcot, UK, investigating the properties of supersonic turbulent jets. For the first time a magneto-optic probe was used to measure the magnetic field in a low-density supersonic turbulent plasma. The results were compared to measurements taken using a magnetic-induction probe. Good agreement was found between measurements of the magnetic field strength within the plasma; however, the magnetic power spectra differ. We attribute this to the dif- ference in integration length between the two measurements. Statistical properties of the velocity field are inferred from the magnetic field measurements, which compare favourably to astrophysical observations and hydrodynamic simulations.

Aburas, Akram. "Operating System Based Perceptual Evaluation of Call Quality in Radio Telecommunications Networks. Development of call quality assessment at mobile terminals using the Symbian operating system, comparison with traditional approaches and proposals for a tariff regime relating call charging to perceived speech quality." Thesis, University of Bradford, 2012. http://hdl.handle.net/10454/5479.

Call quality has been crucial from the inception of telecommunication networks. Operators need to monitor call quality from the end-user's perspective, in order to retain subscribers and reduce subscriber 'churn'. Operators worry not only about call quality and interconnect revenue loss, but also about network connectivity issues in areas where mobile network gateways are prevalent. Bandwidth quality as experienced by the end-user is equally important in helping operators to reduce churn. The parameters that network operators use to improve call quality are mainly from the end-user's perspective. These parameters are usually ASR (answer seizure ratio), PDD (postdial delay), NER (network efficiency ratio), the number of calls for which these parameters have been analyzed and successful calls. Operators use these parameters to evaluate and optimize the network to meet their quality requirements. Analysis of speech quality is a major arena for research. Traditionally, users' perception of speech quality has been measured offline using subjective listening tests. Such tests are, however, slow, tedious and costly. An alternative method is therefore needed; one that can be automatically computed on the subscriber's handset, be available to the operator as well as to subscribers and, at the same time, provide results that are comparable with conventional subjective scores. QMeter® 'a set of tools for signal and bandwidth measurement that have been developed bearing in mind all the parameters that influence call and bandwidth quality experienced by the end-user' addresses these issues and, additionally, facilitates dynamic tariff propositions which enhance the credibility of the operator. This research focuses on call quality parameters from the end-user's perspective. The call parameters used in the research are signal strength, successful call rate, normal drop call rate, and hand-over drop rate. Signal strength is measured for every five milliseconds of an active call and average signal strength is calculated for each successful call. The successful call rate, normal drop rate and hand-over drop rate are used to achieve a measurement of the overall call quality. Call quality with respect to bundles of 10 calls is proposed. An attempt is made to visualize these parameters for better understanding of where the quality is bad, good and excellent. This will help operators, as well as user groups, to measure quality and coverage. Operators boast about their bandwidth but in reality, to know the locations where speed has to be improved, they need a tool that can effectively measure speed from the end-user's perspective. BM (bandwidth meter), a tool developed as a part of this research, measures the average speed of data sessions and stores the information for analysis at different locations. To address issues of quality in the subscriber segment, this research proposes the varying of tariffs based on call and bandwidth quality. Call charging based on call quality as perceived by the end-user is proposed, both to satisfy subscribers and help operators to improve customer satisfaction and increase average revenue per user. Tariff redemption procedures are put forward for bundles of 10 calls and 10 data sessions. In addition to the varying of tariffs, quality escalation processes are proposed. Deploying such tools on selected or random samples of users will result in substantial improvement in user loyalty which, in turn, will bring operational and economic advantages.

An atomic magnetometer is a sensor which is used to measure a magnetic field through its interaction with the atomic sample. Significant research into atomic magnetometry has led to the development of very sensitive atomic sensors capable of matching the sensitivity of the most sensitive magnetometers, superconducting quantum interference devices (SQUIDs). Because SQUIDS require cryogenics to operate, atomic magnetometers provide a sensitive, yet low-cost alternative. They have found use in many areas such as medicine, security, explosives detection and fundamental physics research. One of the primary factors influencing sensitivity is the detuning of the probe beam from the resonant transitions of the atomic ground state. A caesium room temperature radio-frequency (rf) magnetometer is constructed and used to investigate the influence of the probe beam detuning on the magnetometer signal of the F = 3 and F = 4 ground states. The results of probing near and far from resonance revealed an off-resonant regime and two absorptive regimes. In the off-resonant regime, the atomic spins are unperturbed by the probe beam; it is a quantum non-demolition (QND) interaction. The two absorptive regimes, found when the probe beam is in the vicinity of either the 62S1 2 F = 3 → 6 2P3 2 F 0 = 2,3,4 or the 62S1 2 F = 4 → 6 2P3 2 F 0 = 3,4,5 transitions, is characterised as a non-QND interaction in which the probe beam influences the measurement. The sensitivity of the rf magnetometer is determined to be ≈ 1.98 fT/ √ Hz. In addition, the exploration of the relationship between the signal to noise ratio (SNR) and probe beam detuning revealed that the SNR is constant with detuning but the larger the detuning, the higher the probe beam power needs to be to reach the optimum SNR.

Future wireless networks will combine multiple radio technologies and subsystems, possibly managed by competing network providers. For such systems it may be advantageous to let the end nodes (terminals) make some or all of the resource management decisions. In addition to reducing complexity and costs, increasing redundancy, and facilitating more timely decisions; distributed resource sharing regimes can decouple the individual subsystems. Decoupled subsystems could be desirable both because competing operators can be business-wise separated and because it allows new technologies to be added (removed) in a modular fashion. However, distributed regimes can also lead to “selfish” wireless nodes who only try to maximize their own performance. The first part of this dissertation studies if selfish nodes can make efficient use of wireless resources, using multiaccess and network layers as examples. The related problems are formulated as noncooperative games between nodes. To maintain tractability nodes are confined to simple strategies that neither account for future payoffs nor allow for coordination. Yet, it is demonstrated that selfish nodes can achieve comparable performance to traditional protocols. These results should be interpreted as an argument in favor of distributed regimes. The second part of this dissertation evaluates the effects of multi-provider network architectures where users can roam freely across all networks. From a supply side perspective the benefits are improved path gain statistics and the fact that different networks may have non-overlapping busy hours. Several network configurations are analyzed and it is shown that cooperation between symmetric providers can yield significant capacity gains for both downlink and uplink; even if the providers have nearly collocated sites. When the providers have different site densities the gains from cooperation are reduced and the provider with a sparse network always gains more from cooperating. This suggests that initially, voluntary cooperation may be limited to some special cases. Lastly, the architecture is analyzed in a context where the providers compete for users on a per session basis by offering access at different prices. Although such architectures currently only exist in a few special cases, they could emerge in domestic markets where the costs to switch and search for new networks are low. Based on a game theoretic formulation it is shown that a competitive market for wireless access can be advantageous for both users and providers. The results presented suggest that the advantages of cooperation of competing providers occur in more than just a few cases.

Description Ballarat sits on Wathaurong land and is located at the crossroads of four main Victorian highways. A number of State agencies are located here to support and build entrepreneurial activity in the region. The Ballarat Technology Park, located some way out of the heart of the city at the Mount Helen campus of Federation University, is an attempt to expand and diversify the technology and innovation sector in the region. This university also has a high profile presence in the city occupying part of a historically endowed precinct in the city centre. Because of the wise preservation and maintenance of its heritage listed buildings by the local council, Ballarat has been used as the location for a significant set of feature films, documentaries and television series bringing work to local crews and suppliers. With numerous festivals playing to the cities strengths many creative embeddeds and performing artists take advantage of employment in facilities such as the Museum of Australian Democracy at Eureka. The city has its share of start-ups, as well as advertising, design and architectural firms. The city is noted for its museums, its many theatres and art galleries. All major national networks service the TV and radio sector here while community radio is strong and growing.

Geelong and the Surf Coast are treated here as one entity although there are marked differences between the two communities. Sitting on the home of the Wathaurong Aboriginal group, this G21 region is geographically diverse. Geelong serviced a wool industry on its western plains, while manufacturing and its seaport past has left it as a post-industrial city. The Surf Coast has benefitted from the sea change phenomenon. Both communities have fast growing populations and have benefitted from their proximity to Melbourne. They are deeply integrated with this major urban centre. The early establishment of digital infrastructure proved an advantage to certain sectors. All creative industries are represented well in Geelong while many creatives in Torquay are embedded in the high profile and economically dominant surfing industry. The Geelong community is serviced well by its own creative industries with well-established advertising firms, architects, bookshops, gaming arcades, movie houses, music venues, newspaper headquarters, brand new and iconic performing and visual arts centres, libraries and museums, television and radio all accessible in its refurbished downtown area. Co-working spaces, collective practices and entrepreneurial activity are evident throughout the region.

The governments response to the COVID-19 pandemic left Latin America and the Caribbean economies with increased levels of sovereign debt as a percentage of output, bringing up the question of debt sustainability in the region. The literature has identified two testable conditions on the fiscal reaction function for debt sustainability: i) a positive response of primary balances to debt (Bohn, 1995) and ii) the response of primary balances to debt should be higher than the growth adjusted interest rate (Ghosh et al., 2013). This paper revisits these conditions, both from the theoretical and empirical perspective. It introduces a new “implicit growth” measure which is the relevant one for the debt-to-GDP ratio dynamics. It also tests empirically both conditions for economies in the region. The results suggest that debt is likely sustainable in the region, although it cannot be assured at a 95 percent confidence level. A deep look at the causes of this results pointed towards fiscal fatigue, the fact that primary balances become less responsive to debt levels the higher the latter are. At post-pandemic debt levels sustainability is far from certain. The results here indicate decisive action is required to ensure debt will fall back to prudent levels.

This study was conducted in selected provinces of Bicol Region from April 2015 to May 2015 to describe the knowledge, attitudes and practices (KAP) of dog owners regarding rabies and dog bites. A purposive sampling was used in selecting the respondents of the study. Frequencies were tabulated for all variables. Of the 1,200 respondents, 2,193 dogs were recorded making a 2:1 ratio of dogs to householders in this particular study. Among these dogs 58% were vaccinated against rabies. The majority of the ones taking care of the dogs were female (57.3%) but the primary owner (62.9%) was the head of the family. Only 34.7% of the respondents knew that it is their duty to get their pets vaccinated against rabies. Around one-fourth (20.7%) admitted that someone in their household had been bitten by a dog but most respondents (62.5%) did nothing to the dog. The majority (57.7%) of the bite victims were youths (1-14 years old) and almost all (82.7%) of the wound bites were washed with soap and water. Television (44.9%) was the primary source of knowledge about rabies. The majority of participants (67.3%) said that humans are the main end-hosts that can be infected with rabies. Salivation or drooling (42.7%) and craziness (34.2%) were the main signs cited as behaviour of rabid dogs while craziness (40.2%) and hydrophobia or fear of water (25.4%) were cited for rabid humans. Most (33.9%) do not know the source of rabies but the majority (61.8%) believe that vaccination is the main preventive measure against rabies. The majority of participants (63%) reported that the local ordinances regarding rabies in their locality is about the Local Anti-Rabies Act and almost all (93.2%) admitted that vaccination is the most common anti-rabies program of the government.

Повний текст джерела
Анотація:
Testing normality against discrete normal mixtures is complex because some parameters turn increasingly underidentified along alternative ways of approaching the null, others are inequality constrained, and several higher-order derivatives become identically 0. These problems make the maximum of the alternative model log-likelihood function numerically unreliable. We propose score-type tests asymptotically equivalent to the likelihood ratio as the largest of two simple intuitive statistics that only require estimation under the null. One novelty of our approach is that we treat symmetrically both ways of writing the null hypothesis without excluding any region of the parameter space. We derive the asymptotic distribution of our tests under the null and sequences of local alternatives. We also show that their asymptotic distribution is the same whether applied to observations or standardized residuals from heteroskedastic regression models. Finally, we study their power in simulations and apply them to the residuals of Mincer earnings functions.

Objectives: We seek to establish the basis for improving cotton productivity under arid conditions, by studying the water use efficiency - evaporative cooling interrelationship. Specifically, we will test the hypothesis that cotton productivity under arid conditions can be improved by combining high seasonal WUE with efficient evaporative cooling, evaluate whether high WUE and/or evaporative cooling are based on specific physiological factors such as diurnal flexibility in stomatal conductance, stomatal density, photosynthetic capacity, chlorophyll fluorescence, and plant water status. Genes influencing both WUE and evaporative cooling, as well as other parameters such as economic products (lint yield, quality, harvest index) of cotton will also be mapped, in order to evaluate influences of water relations on these parameters. Approach: Carbon isotope ratio will be used to evaluate WUE, accompanied by additional parameters to elucidate the relationship between WUE, evaporative cooling, and cotton productivity. A detailed RFLP map will be used to determine the number, location, and phenotypic effects of genes underlying genetic variation in WUE between cultivated cottons, as well as test associations of these genes with traits of economic importance such as harvest index, lint yield, and lint quality. Major Conclusions: Productivity and quality of cotton grown under well-watered versus water-limited conditions was shown to be partly accounted for by different quantitative trait loci (QTLs). Among a suite of physiological traits often found to differ between genotypes adapted to arid versus well-watered conditions, genetic mapping implicated only reduced plant osmotic potential in improved cotton productivity under arid conditions. Our findings clearly implicate OP as a major component of cotton adaptation to arid conditions. However, testing of further physiological hypotheses is clearly needed to account for additional QTL alleles conferring higher seed-cotton yield under arid conditions, such as three of the five we found. Near-isogenic lines being made for QTLs discovered herein will offer a powerful new tool useful toward identification of the underlying gene(s) by using fine-scale mapping approaches (Paterson et al 1990). Implications: Adaptation to both arid and favorable conditions can be combined into the same genotype. We have identified diagnostic DNA markers that are being applied to creation of such desirable genotypes. Simultaneous improvement of productivity (and/or quality) for both arid and irrigated conditions will require more extensive field testing and the manipulation of larger numbers of genes, reducing the expected rate of genetic gain These difficulties may be at least partly ameliorated by efficiencies gained through identification and use of diagnostic DNA markers. Genomic tools and approaches may expedite adaptation of crops to arid cultivation, help to test roles of additional physiological factors, and guide the isolation of the underlying genes that protect crop performance under arid conditions.
