Around 80% of the 63 million people in the UK live in urban areas where demand for affordable housing is highest. Supply of new dwellings is a long way short of demand and with an average annual replacement rate of 0.5% more than 80% of the existing residential housing stock will still be in use by 2050. A high proportion of owner-occupiers, a weak private rental sector and lack of sustainable financing models render England’s housing market one of the least responsive in the developed world. As an exploratory research the purpose of this paper is to examine the provision of social housing in the United Kingdom with a particular focus on England, and to set out implications for housing associations delivering sustainable community development. The paper is based on an analysis of historical data series (Census data), current macro-economic data and population projections to 2033. The paper identifies a chronic undersupply of affordable housing in England which is likely to be exacerbated by demographic development, changes in household composition and reduced availability of finance to develop new homes. Based on the housing market trends analysed in this paper opportunities are identified for policy makers to remove barriers to the delivery of new affordable homes and for social housing providers to evolve their business models by taking a wider role in sustainable community development.

In this talk we will review some of the key enabling technologies of optical communications and potential future bottlenecks. Single mode fibre (SMF) has long been the preferred waveguide for long distance communication. This is largely due to low loss, low cost and relative linearity over a wide bandwidth. As capacity demands have grown SMF has largely been able to keep pace with demand. Several groups have been identifying the possibility of exhausting the bandwidth provided by SMF [1,2,3]. This so called “capacity-crunch” has potentially vast economic and social consequences and will be discussed in detail. As demand grows optical power launched into the fibre has the potential to cause nonlinearities that can be detrimental to transmission. There has been considerable work done on identifying this nonlinear limit [4, 5] with a strong re- search interest currently on the topic of nonlinear compensation [6, 7]. Embracing and compensating for nonlinear transmission is one potential solution that may extend the lifetime of the current waveguide technology. However, at sufficiently high powers the waveguide will fail due to heat-induced mechanical failure. Moving forward it be- comes necessary to address the waveguide itself with several promising contenders discussed, including few-mode fibre and multi-core fibre.

Az Amerikai Egyesült Államok – mint a világ gazdaságilag és katonailag legerősebb hatalma – hamarosan leküzdi a jelenlegi válságot és továbbra is vezető hatalom marad. Európában a főbb tennivalókat továbbra is a demográfiai helyzet, a migráció kezelése és az összeurópai intézmények kialakítása jelenti. A szovjet utódállamok etnikai feszültségekkel és demográfiai hanyatlással, továbbá az orosz befolyás erősödésével számolhatnak. A háborús térségekben a feszültség nem fog csökkenni – Irak, Afganisztán Irán, Észak-Afrika és a Közel-Kelet továbbra is a figyelem középpontjában lesz. Kína gazdasági növekedése következtében a világ második legnagyobb hatalmává léphet elő. Összességében megállapítható, hogy a világ az elmúlt években nem lett biztonságosabb és ez a tendencia folytatódik 2011-ben is. / === / The economic and political processes experienced in the world are followed by great attention not only by experts, but also by public opinion. The most important conclusions of the study are as follows: the United States – as the economically and politically strongest power in the world – will soon overcome the present crisis and preserve its leading power status. The main task in Europe will remain handling the demographic decline and migration, as well as to establish appropriate pan-European institutions. The post-Soviet successor states are facing ethnical tensions and demographic decline. In addition , they cannot resist the strengthening Russian influence. The tension in the war-zones is not expected to significantly ease, Iraq, Afghanistan, North Africa and the Middle East will remain high on the world's agenda. China – thanks to its economic growth – is going to become the second greatest power of the world. In the study we can read in detail about the development tendencies of the regions and states. To sum up, the world has not become safer at all in the past years and this tendency will continue also in 2011.

A 2012-es év várhatóan nem hoz radikális változást a világgazdaságban és a világpolitikában, meglepetésekkel azonban számolni kell. A gazdasági válság hatását nemcsak Európában, hanem azon kívül is érzékeljük, a válság rányomja bélyegét az érintett államok belpolitikájára és nemzetközi kapcsolataira. Az Egyesült Államok meghatározó tényező marad 2012-ben, még akkor is, ha ezt néhányan vitatják. A BRIC államok kimagasló mutatóik ellenére sem vonhatják ki magukat a válság hatása alól. 2012-ben az Egyesült Államok új védelmi stratégiát adott ki, amelyben egyértelműen kimutathatók a háborúk következményei. Az Al Kaida terrorszervezet ugyan jelentősen meggyengült, de a dzsihádizmussal továbbra is számolni kell, főként a válságkörzetekben. ______________ The year 2012 will probably not bring radical changes in the global economy and world policy. However, one should count on surprises. The results of the economic crisis are felt not only in Europe but outside Europe as well and it will have an effect on the domestic politics and on the international connections of the respective countries. The United States will remain a determinant factor in 2012 as well, although even if some dispute this observation. The BRIC states, in spite of theirs outstanding economic achievements, cannot avoid the detrimental effects of the crisis. As for security policy, the USA delivered a new defence strategy in 2012 that summarises the consequences of the wars. Although Al-Qaida lost its strength remarkably, one has to count on jihadism mainly in crisis areas.

The paper addresses five issue areas. First it describes the plurality of trajectories in central and eastern European transformations, offering a broad typology. Then it addresses the drift between acceptance of democracy and the market, owing to growing inequalities. Third, problems of poverty and exclusion are addressed. Fourth, it is addressed if any known model of redistribution emerged in the post-transition economies. Fifth, consequences of the populist turn in European policies are being analyzed. Influences of the EU practices will be dealt with and some preliminary conclusions drawn. These suggest a strong intertwining between social and economic performance that limit theoretically conceivable – neoliberal, social democratic, postmodern or conservative - policy choices.

The importance of advertising has changed in many aspects in the last decade, and mainly during the last years of the economic crisis. Economics traditionally did not find advertising a valuable factor until empirical studies demonstrated that advertisement affects consumer perception by means of indicating the quality of the underlying product. Consequently, products that are advertised more frequently, are more likely to be associated with a higher quality. Nevertheless, advertising is a strong tool in competition, which statement is confirmed by the recognition that increasing consumer knowledge contributes to the diffusion of innovation and to the reduction of research and development (R&D) costs. This contribution can be achieved nowadays by consumer interactivity, where companies deliberately rely on the involvement of their consumers. Recently, when companies were confronted to the global economic crisis, brand managers realized that allocating advertising budgets in a recession (considering the actual state of the economic conditions) is a highly important decision factor beside competition, consumer behaviour, trends or industrial conditions. Companies have to realize that their communication budgets are planned substantially in a different way in times of crisis than during an upsurge. Moreover, should a company make the best of maintaining their advertising budgets in recession times, it will indicate more trust towards their consumers and show a more favorable image towards their investors. This study assembles different approaches from the economics of advertising to draw conclusions for the subsequent analyses of advertising in times of a crisis. The main objective with the literature review is to show, that pro-cyclical actions (reducing advertising budgets in times of crisis and overspending during upsurge) of companies can lead to problems of profitability, consumer trust and competitiveness in the long run.

Pessimistic Malthusian verdicts on the capacity of pre-industrial European economies to sustain a degree of real economic growth under conditions of population growth are challenged using current reconstructions of urbanisation ratios, the real wage rates of building and agricultural labourers, and GDP per capita estimated by a range of methods. Economic growth is shown to have outpaced population growth and raised GDP per capita to in excess of $1,500 (1990 $ international at PPP) in Italy during its twelfth- and thirteenth-century commercial revolution, Holland during its fifteenth- and sixteenth-century golden age, and England during the seventeenth- and eighteenth-century runup to its industrial revolution. During each of these Smithian growth episodes expanding trade and commerce sustained significant output and employment growth in the manufacturing and service sectors. These positive developments were not necessarily reflected by trends in real wage rates for the latter were powerfully influenced by associated changes in relative factor prices and the per capita supply of labour as workers varied the length of the working year in order to consume either more leisure or more goods. The scale of the divergence between trends in real wage rates and GDP per capita nevertheless varied a great deal between countries for reasons which have yet to be adequately explained.

Skeletal maturity is used to evaluate biological maturity status. Information about the association between socio-economic status (SES) and skeletal maturity is limited in Portugal. Aims: The aim of this study is to document the skeletal maturity of youths in Madeira and to evaluate variation in maturity associated with SES. Subjects and methods: The study involved 507 subjects (256 boys and 251 girls) from the Madeira Growth Study, a mixed-longitudinal study of five cohorts (8, 10, 12, 14 and 16 years of age) followed at yearly intervals over 3 years (1996–1998). A total of 1493 observations were made. Skeletal age was estimated from radiographs of the hand and wrist using the Tanner–Whitehouse 2 method (TW2). Social class rankings were based on Graffar’s (1956) method. Five social rankings were subsequently grouped into three SES categories: high, average and low. Results: Median for the radius, ulna and short finger bones (RUS scores) in the total sample of boys and girls increased curvilinearly across age whereas median for the 7 (without pisiform) carpal bones (Carpal scores) increased almost linearly. The 20-bone maturity scores demonstrated distinctive trends by gender: the medians for boys increased almost linearly while the medians for girls increased curvilinearly. SES differences were minimal. Only among children aged 10–11 years were high SES boys and girls advanced in skeletal maturity. Madeira adolescents were advanced in skeletal maturity compared with Belgian reference values. Conclusion: The data suggests population variation in TW2 estimates of skeletal maturation. Skeletal maturity was not related to SES in youths from Madeira.

Sunflower cropped area in Brazil has been showing potential possibilities to be increased in a short period of time for biofuel production. Planning the activities is one of the requirements for the success of future cropped area expansion. This requires a previous survey that identifies future trends in the transformation and rearrangement of the sunflower agro-industry sector and also identifies technological needs that may affect this process. With the objectives of identify future trends and technological needs, a value production chain was built and a questionary was applied to agents of all the sectors participating at the V National Brazilian Symposium of Sunflower and at the XVII Sunflower National Research Meeting Network. The results pointed out a strong tendency for area expansion in the next two to five years (75%); being as a secondary follow-up crop (83%) specially after soybean and top be used for biofuel (77%). The main research needs were linked with disease control, crop zoning and varietal improvement for disease resistance and high oleic oil content. Also considering the vision of and concerns regarding the future expansion and transformation of the sunflower productive complex, it is believed that the expansion is a consolidated trend, requiring a strategic sector planning associated with an economic and technological police for its success within the Brazilian agribusiness.

This thesis is a combination of research questions in development economics and economics of culture, with an emphasis on the role of ancestry, gender and language policies in shaping inequality of opportunities and socio-economic outcomes across different segments of a society. The first chapter shows both theoretically and empirically that heterogeneity in risk attitudes can be traced to the ethnic origins and ancestral way of living. In particular, I construct a measure of historical nomadism at the ethnicity level and link it to contemporary individual-level data on various proxies of risk attitudes. I exploit exogenous variation in biodiversity to build a novel instrument for nomadism: distance to domestication points. I find that descendants of ethnic groups that historically practiced nomadism (i) are more willing to take risks, (ii) value security less, and (iii) have riskier health behavior. The second chapter evaluates the nature of a trade-off between the advantages of female labor participation and the positive effects of female education. This work exploits a triple difference identification strategy relying on exogenous spike in cotton price and spatial variation in suitability for cotton, and split sample analyses based on the exogenous allocation of land contracts. Results show that gender differences in parental investments in patriarchal societies can be reinforced by the type of agricultural activity, while positive economic shocks may further exacerbate this bias, additionally crowding out higher possibilities to invest in female education. The third chapter brings novel evidence of the role of the language policy in building national sentiments, affecting educational and occupational choices. Here I focus on the case of Uzbekistan and estimate the effects of exposure to the Latin alphabet on informational literacy, education and career choices. I show that alphabet change affects people's informational literacy and the formation of certain educational and labour market trends.

In this manuscript we briefly describe bipolar disorder (a depressive and manic mental disease), its classification, its effects on the patient, which sometimes include suicidal tendencies, and the drugs used for treatment. We also address the status quo with regard to diagnosis of bipolar disorder and recent advances in bioanalytical approaches for biomarker discovery. These approaches focus on blood samples (serum and plasma) and proteins as the main biomarker targets, and use various strategies for protein depletion. Strategies include use of commercially available kits or other homemade strategies and use of classical proteomics methods for protein identification based on bottom-up or top-down approaches, which used SELDI, ESI, or MALDI as sources for mass spectrometry, and up-to-date mass analyzers, for example Orbitrap. We also discuss some future objectives for treatment of this disorder and possible directions for the correct diagnosis of this still-unclear mental illness.
