Abstract Eero, M. 2012. Reconstructing the population dynamics of sprat (Sprattus sprattus balticus) in the Baltic Sea in the 20th century. – ICES Journal of Marine Science, 69: 1010–1018 . Long time-series of population dynamics are increasingly needed in order to understand human impacts on marine ecosystems and support their sustainable management. In this study, the estimates of sprat (Sprattus sprattus balticus) biomass in the Baltic Sea were extended back from the beginning of ICES stock assessments in 1974 to the early 1900s. The analyses identified peaks in sprat spawner biomass in the beginning of the 1930s, 1960s, and 1970s at ∼900 kt. Only a half of that biomass was estimated for the late 1930s, for the period from the late 1940s to the mid-1950s, and for the mid-1960s. For the 1900s, fisheries landings suggest a relatively high biomass, similar to the early 1930s. The exploitation rate of sprat was low until the development of pelagic fisheries in the 1960s. Spatially resolved analyses from the 1960s onwards demonstrate changes in the distribution of sprat biomass over time. The average body weight of sprat by age in the 1950s to 1970s was higher than at present, but lower than during the 1980s to 1990s. The results of this study facilitate new analyses of the effects of climate, predation, and anthropogenic drivers on sprat, and contribute to setting long-term management strategies for the Baltic Sea.

AbstractRecords of discharge of rivers draining Alpine basins with between 0 and ~70% ice cover, in the upper Aare and Rhône catchments, Switzerland, for the period 1894–2006 have been examined together with climatic data for 1866–2006, with a view to assessing the effects on runoff from glacierized basins of climatic warming coupled with glacier recession following the Little Ice Age maximum. Annual runoff from ice-free basins reflects precipitation variations, rising from minima between 1880 and 1910 to maxima between the late 1960s and early 1980s. The more highly glacierized the basin, the more runoff mimicked mean May–September air temperature during two periods of warming. Runoff increased gradually from the 1900s, rapidly in the 1940s, before decreasing to the late 1970s. Rising runoff levels during the second warming period failed to exceed those attained during the first, despite higher summer temperatures. Although temperatures continued to rise, discharge from glacierized basins declined after reaching maxima in the late 1980s to early 1990s. In the first warming period, rising specific melt rates augmented by increasing precipitation opposed the impact of declining glacier area on runoff. Although melt continued to increase in the second period, enhanced melting (even in the exceptionally warm summer of 2003) appears to have been insufficient to offset reducing glacier surface area exposed to melt, low or reducing levels of precipitation, and increasing evaporation. Thus runoff from glacierized basins peaked in the late 1940s to early 1950s.

The similarity in water environment variation course and economic development of the Taihu Lake riverbasin and Japan is analyzed and harnessing countermeasures are introduced. The close relation between economic development and water environment is analyzed. It is suggested that coordinated development policy of “Population-Resources-Environment-Economy” should be adopted. The research results demonstrate that water quality variation trend of the Taihu Lake riverbasin in the period of 1980s-the late 1990s was very similar the that of Japan in the period of 1960s-1980s, the rapid economic development of the Taihu Lake Riverbasin in the 1980s-1990s was similar to that of Japan rapid economic development period of 1960s.-1970s, the economic development level and water environment state of Japan in 1970 was very similar to that of the Taihu Lake Riverbasin in 1998,the economic development and water environment variation of the Taihu Lake riverbasin lags behind 20 plus years than that of Japan. We can infer the present and future situation of the Taihu Lake according to the history and present social-economic and water environment development situation of Japan.

Full textAbstract:
AbstractThe present paper discusses the interplay between the Soviet state policy towards indigenous languages of "Northern Minorities" and the attitudes of the indigenous communities to their languages and to language endangerment. The author uses statistics on the Soviet state program of publishing books (primarily school books) in indigenous languages that was launched in the late 1920s and underwent considerable changes in the course of the decades to follow. It is argued that the publishing policy for all languages of indigenous minorities of the Far North followed the same consistent pattern that included several phases: "a glorious beginning" in the 1930s interrupted by the war, then a strong continuation in the 1950s, then a drop in the 1960-70s, and a resurrection in the 1980s, interrupted by the economic crisis of the early 1990s. The most interesting and the least clear period is the two and a half decades between mid-1950s and late 1970s where changes of the state policy may be connected with changes in community attitudes towards their native languages. A successful policy of language preservation and revitalization is possible only if it is supported simultaneously by the state and the indigenous community.

Abstract PURPOSE: Pediatric low-grade glioma therapy has evolved to delay or eliminate radiation. The impact of therapy changes on long-term outcomes remains unknown. METHODS: Cumulative incidence of late mortality (death >5 years from diagnosis), subsequent neoplasms (SNs), and chronic health conditions (CHCs, CTCAE grading criteria) were evaluated in the Childhood Cancer Survivor Study among 5-year survivors of glioma diagnosed 1970-1999. Outcomes were evaluated by diagnosis decade and by treatment exposures received ≤5 years following diagnosis (surgery-only, chemotherapy ± surgery, and cranial radiation ± surgery or chemotherapy). Relative risk (RRs) with 95%CIs estimated long-term outcomes using multivariable piecewise exponential models. RESULTS: Among 2,684 eligible survivors (age at diagnosis (median [range]), 7 years [0-20 years]; time from diagnosis, 24 years [5-48 years]), exposure to cranial radiation decreased [51% (1970s), 45% (1980s), 25% (1990s)] along with late tumor recurrence (>5 & ≤15 years from diagnosis) [9.8% (1970s), 8.8% (1980s), 5.0% (1990s)]. The 15-year cumulative incidence of late mortality was 10.3% (1970s), 6.5% (1980s), and 6.0% (1990s) (p<0.001, comparison of cumulative incidence curves). The 15-year cumulative incidence of grade 3-5 CHCs was 19.7% (1970s), 17.8% (1980s), and 14.2% (1990s) (p<0.0001). A reduction in SN incidence was not observed. In multivariable analyses excluding treatment exposure, later diagnosis (1990s vs. 1970s) was associated with lower risk of late mortality, grade 3-5 CHCs and SNs. Inclusion of treatment exposure in the model attenuated the effect of diagnosis decade. Radiation or chemotherapy exposure increased risk compared to surgery alone for late mortality (radiation RR 4.95, 95%CI 3.79-6.47; chemotherapy RR 2.88, 95%CI 1.85-4.48), CHCs (radiation RR 4.02, 95%CI 3.28-4.94; chemotherapy RR 1.66, 95%CI 1.13-2.45), and SNs (radiation RR 4.02, 95%CI 3.06-6.13, chemotherapy RR 2.08, 95%CI 1.03-4.23)). CONCLUSION: Late mortality and CHCs decreased in childhood glioma survivors diagnosed from 1970-1999 largely due to therapy changes, particularly avoidance of cranial radiation, without increased late recurrence.

AbstractCHD affects millions of patients worldwide. Interventional therapies for CHD goes back to the mid-1960s when Bill Rashkind performed balloon atrial septostomy on a cyanotic baby with transposition of the great vessels. This was followed by development of balloon catheters to perform balloon valvuloplasties and angioplasties in the early to late 1980s. Although King and Mills performed the first transcatheter closure of secundum atrial septal defect in the mid-1970s, this procedure was better realised in the mid-1990s. More intracardiac defect closures were performed in the late 1990s and early 2000. This brings us to the current era of percutaneous valve implantation as developed by Bonhoeffer. In this paper, we will discuss the past, present, and future of interventional cardiac catheterisation for CHD patients.

Full textAbstract:
We analyzed the temporal trends and significant changes in apparent energy and macronutrient intakes in the Bangladeshi diet from 1961 to 2017. Due to the lack of a long-running national dietary intake dataset, this study used the Food and Agriculture Organization (FAO)’s old and new food balance sheet dataset. We used the joinpoint regression model and jump model to analyze the temporal trends in apparent energy and macronutrient intakes. The annual percentage change (APC) was computed for each segment of the trends. Bangladesh has experienced a late energy revolution in their dietary history. During the 1960s, 1970s, 1980s, and 1990s, Bangladesh was suffering from substantive calorie deficits, where in apparent energy intake was less than 2200 kcal/day/person. Since the late 1990s, Bangladesh has made significant progress in raising the apparent energy consumption in the diet. Since the late 1970s, apparent fat intake started to increase significantly at a marked rate (APC = 2.16), whereas since the early 1990s, protein intake increased significantly by 1.33% per year. Plant sources have mostly governed the protein and fat intake trends in the Bangladeshi diet since 1960, whereas animal sources began to contribute significantly in protein intake since 1990 (APC = 3.43) and in fat intake since 2000 (APC = 2.88). Bangladesh overcame the substantive calorie deficit condition in the diet from the late 1990s. Excessive carbohydrate intake along with imbalanced and low-quality protein and fat intakes have been the central features in the diet in Bangladesh.

Full textAbstract:
This paper demonstrates that the key determinants of policy success have been policymakers' views about how the economy works and what monetary policy can accomplish. In the first major section of the paper, the authors analyze the narrative record of the Federal Reserve to discover what policymakers believed and why they chose the policies they did. The authors find that the well-tempered monetary policies of the 1950s and of the 1980s and 1990s stemmed from a conviction that inflation has high costs and few benefits, together with realistic views about the sustainable level of unemployment and the determinants of inflation. In contrast, the profligate policies of the late 1960s and 1970s stemmed initially from a belief in a permanent tradeoff between inflation and unemployment, and later from a natural rate framework with a highly optimistic estimate of the natural rate of unemployment and a highly pessimistic estimate of the sensitivity of inflation to economic slack. And the deflationary policies of the late 1930s stemmed from a belief that the economy could overheat at low levels of capacity utilization and that monetary ease could do little to stimulate a depressed economy.

10007 Background: Therapy for pediatric low-grade glioma has evolved to delay or eliminate the need for cranial radiation. The impact of this change in approach on long-term outcomes remains unknown. Methods: Cumulative incidence of late mortality (death ≥5 years from diagnosis), subsequent neoplasms (SNs), and chronic health conditions (CHCs, graded using CTCAE criteria) were evaluated in the Childhood Cancer Survivor Study among 5-year survivors of glioma diagnosed between 1970 and 1999. Outcomes were evaluated by diagnosis decade (1970s, 1980s, 1990s) and by treatment exposure in the first five years from diagnosis [surgery only, chemotherapy (with or without surgery), and cranial radiation (with or without surgery or chemotherapy)]. Relative Risk (RRs) with 95% CIs estimated long-term outcomes using multivariable piecewise exponential models. Results: Among 2,684 eligible survivors (median age at diagnosis, 7 years [range, 0 to 20 years]; median time from diagnosis, 24 years [range, 5 to 48 years]), the proportion exposed to cranial radiation decreased from 51% (1970s) to 45% (1980s) and 25% (1990s) while the rate of recurrence within > 5 years but ≤15 years of diagnosis decreased from 9.8% (1970s) to 8.8% (1980s) and 5.0% (1990s). The 15-year cumulative incidence rate of all-cause late mortality was 10.3% (1970s), 6.5% (1980s), and 6.0% (1990s) (p < 0.001, comparison of cumulative incidence curves). The 15-year cumulative incidence rates of severe, disabling or life-threatening (grade 3-5) CHCs also decreased between 1970 and 1999: 19.7% (1970s), 17.8% (1980s), and 14.2% (1990s) (p < 0.0001). Lower rates of SN were not observed. In a multivariable analysis adjusted for age at diagnosis, attained age, race, sex and diagnosis decade, later diagnosis (1990s vs. 1970s) was associated with lower risk of late mortality (RR 0.86, 95% CI 0.74-0.99), grade 3-5 CHCs (RR 0.65, 95% CI 0.51-0.82) and SN (RR 0.64, 95% CI 0.44-0.94). In addition, when treatment exposure was added to the multivariable model, the effect of diagnosis decade was attenuated and no longer significant. Exposure to radiation or chemotherapy both increased risk compared to surgery alone: all-cause mortality (radiation RR 4.95, 95% CI 3.79-6.47; chemotherapy RR 2.88, 95% CI 1.85-4.48), grade 3-5 CHCs (radiation RR 4.02, 95% CI 3.28-4.94; chemotherapy RR 1.66, 95% CI 1.13-2.45), SNs (radiation RR 4.02, 95% CI 3.06-6.13, chemotherapy RR 2.08, 95% CI 1.03-4.23)). The effect of delayed radiation (> 1year to ≤5 years from diagnosis) on all-cause late mortality, grade 3-5 CHCs, or SNs was not different compared to radiation within one year of diagnosis. Conclusions: Late mortality and CHCs decreased in childhood glioma survivors diagnosed from 1970-1999 largely due to therapy changes, particularly avoidance of cranial radiation, without increased late recurrence.

We use several national surveys to provide a 50-year perspective on time spent on homework. The great majority of American children at all grade levels now spend less than one hour studying on a typical day—an amount that has not changed substantially in at least 20 years. Moreover, high school students in the late 1940s and early 1950s studied no more than their counterparts did in the 1970s, 1980s, and 1990s. Changes in educational opinion on homework over the last half century have had little effect on student behavior, with only two notable exceptions: a temporary increase in homework time in the decade following Sputnik, and a new willingness in the last two decades to assign small amounts to primary-grade students.

Full textAbstract:
It has been argued repeatedly that British health policy in the 1990s had a number of similarities with that of the 1930s. This article, while accepting that a comparison of these two periods may be useful, argues that comparing policy in the 1950s with that in the 1980s and 1990s is even more illuminating. To demonstrate this the author outlines first the similarities in policy between the early and later periods, then the differences, and the events that led to each. These comparisons suggest that there is evidence of path dependency in British health policy, and although the United Kingdom appeared to break away from the policy path for a short time in the late 1980s, the changes proposed then do not appear to have been as radical as first suggested. Many of the issues highlighted in the 1950s seem to remain unresolved today.

Abstract First hydroelectric power stations in Poland were built in 19th century, mostly in the region of Podhale (Carpathian tributaries of the Vistula River) and in the Old Polish Industrial District (for the needs of the iron and steel industry) from the initiative of Stanisław Staszic. They were used in mills and saw mills, for home lighting in settlements, etc. After World War I two medium size hydroelectric power stations were constructed in Pomerania (Gródek and Żar) and the construction of a dam (at that time the largest in Europe) was started in Rożnów on the Dunajec River (50 MW); the hydroelectric power station was opened as late as 1941. A small growth in this field took place in the 1950s and 1960s, and in the late 1960s / early 1970s large hydroelectric power stations were built (Solina, Włocławek, Żydowo). The largest growth occurred in the late 1980s and early 1990s, when the two giant peak-load, pumped-storage power stations were put into operation (Porąbka-Żar: 500 MW and Żarnowiec: 680 MW), reaching the total power of 2000 MW. The most recent two large installations are: Czorsztyn-Niedzica (92 MW, 1997) and the modernisation of Solina (200 MW, 2003).

In this survey article, after delineating its historical origin of the Efficient Market Hypothesis (EMH), the authors summarize from the methodological perspective the empirical findings from 1960s through 1990s bearing on the EMH under the headings "supporting empirical findings as documented in 1960s", "mixed empirical findings as merged in the late 1970s through 1980s" and "challenging empirical findings as appeared in 1990s". The authors move on to sketch the ongoing debate in the 21st century based on empirical evidence available and then present an overall assessment of the EMH. Once necessary reservations and precautious interpretations are taken into consideration, the authors contend at the end of the article that the EMH is here to stay and will continue to play an important role in modern finance for years to come.

Full textAbstract:
Records of discharge from partially-glacierised basins in the upper Rhône catchment, Switzerland, were examined together with air temperature and precipitation data in order to assess impacts of climatic fluctuation and percentage glacierisation of basin on runoff, as glaciers declined from dimensions attained during the Little Ice Age. Above 60% glacierisation, year-to-year variations in runoff mimicked mean May–September air temperature, rising in the warm 1940s, declining in the cool 1970s, before increasing (by 50%) into the warm dry 1990s/2000s but not reaching 1940s maxima. In basins with between 35–60% glacierisation, flow also increased into the 1980s but waned through the 1990s. With less than 2% glacierisation, the pattern of runoff was broadly the inverse of that of temperature and followed precipitation, dipping in the 1940s, rising in the cool wet late 1960s, and declining into the 1990s/2000s, with glacier melt in warm years being insufficient to offset lack of precipitation. On mid-sized glaciers at relatively low elevations and with limited vertical extent, in warmer years, the transient snow line was above the highest point of the glacier. Only on large glaciers descending from high elevations can rising transient snowlines continue to expose more ice to melt. Runoff from such large glaciers was enhanced in warm summers but reduction of overall ice area through glacier recession led to runoff in the warmest summer (2003) being lower than the previous peak discharge recorded in the second warmest year (1947).

We aimed to analyze the temporal trends in the per capita food (kcal/day/person) and protein (g/day/person) availability at the national level in the Southeast Asian (SEA) countries from 1961 to 2018. To avoid intercountry variations and errors, we used a dataset derived from the FAO’s old and new food balance sheets. We used the joinpoint model and the jump model to analyze the temporal trends. The annual percentage change (APC) was computed for each segment of the trends. Per capita food and protein availability in the SEA countries increased significantly by 0.8% per year (54.0%) and 1.1% per year (85.1%), respectively, from 1961 to 2018. During the 1960s, 1970s, and 1980s the per capita food availability in mainland SEA did not change significantly and was less than 2200 kcal/person/day. Since the early 1990s, food availability increased appreciably in the mainland SEA countries, except for Cambodia, which has experienced the increasing trend from the late 1990s. Distinct from the mainland, maritime SEA countries showed an up–down–up growth trend in their per-capita food availability from 1961 to 2018. Food-availability growth slowed down for Brunei (since the mid-1980s) and Malaysia (since mid-the 1990s) whereas it increased for Indonesia (1.5% per year), Timor-Leste (0.9% per year), and the Philippines (0.8% per year). Per capita protein availability trends in the mainland SEA countries were similar to the countries’ per capita food availability trends. Since the late 1980s, Thailand and since the late 1990s, other mainland SEA countries experienced a significant growth in their per capita protein availability. Since the late 1990s, per capita protein availability in Vietnam increased markedly and reached the highest available amount in the SEA region, following Brunei and Myanmar. Per capita protein availability increased almost continuously among the maritime SEA countries, except for Timor-Leste. Marked inequality did exist between maritime and mainland SEA countries in per capita food-availability growth till the mid-1990s. Considerable increases in per capita food availability have occurred in most of the SEA countries, but growth is inadequate for Timor-Leste and Cambodia.

Abstract Inaugurated in January 1954, the ‘Minoan Linear B Seminar’ explored the information emerging from Ventris' decipherment of Linear B in 1952. The new academic discipline of ‘Mycenaean Studies’ rapidly moved on from questions influenced by the field's ‘pre-history’ dating back a further 60 years to Evans' first publication on Aegean scripts. Intense philological and epigraphical research in the 1950s and 1960s laid the foundations for comparative study of the Mycenaean palatial societies, while a greater appreciation of archaeological data and contexts moved interpretation on in the 1980s and 1990s. Building on this tradition, Mycenaean studies currently needs more documents to sustain a ‘critical mass’ of researchers and, ideally, a new Ventris to unlock the Aegean scripts that remain undeciphered.

ABSTRACTThis paper analyzes Joan Robinson's growth model, and then adapted in order to provide an exploratory taxonomy of Growth Eras. The Growth Eras or Ages were for Robinson a way to provide logical connections among output growth, capital accumulation, the degree of thriftiness, the real wage and illustrate a catalogue of growth possibilities. This modified taxonomy follows the spirit of Robinson's work, but it takes different theoretical approaches, which imply that some of her classifications do not fit perfectly the ones here suggested. Latin America has moved from a Golden Age in the 1950s and 1960s, to a Leaden Age in the 1980s, having two traverse periods, one in which the process of growth and industrialization accelerated in the late 1960s and early 1970s, which is here referred to as a Galloping Platinum Age, and one in which a process of deindustrialization, and reprimarization and maquilization of the productive structure took place, starting in the 1990s, which could be referred to as a Creeping Platinum Age.

Full textAbstract:
During the last century the technological advances in the field of spinal surgery had a dramatic impact on the treatment of spinal deformity in children and adults. Before the advent of medications and vaccines to treat and/or prevent tuberculosis and poliomyelitis, patients suffering from these disorders often became incapacitated by the resulting kyphoscoliosis. In the early 1900s Lange began to address this problem mechanically by using foreign materials to stabilize the spine internally. In the 1950s and 1960s, owing to the efforts of Harrington and others, the process evolved to create the first generation of modern spinal instrumentation. The Harrington rod was able to correct a spinal deformity primarily through distraction. In the next wave of advances, some of the shortcomings of Harrington rods were addressed. Segmental fixation involving sublaminar wires was introduced in the 1970s by Luque. Anterior approaches and instrumentation-related techniques developed by Zielke and colleagues as well as Dywer and coworkers in the late 1960s and mid-1970s allowed for better correction of deformity with immobilization of fewer motion segments compared with posterior surgery. Transpedicular fixation of the spine was popularized by Cotrel and Dubousset in the 1980s; they used the technique to perform segmental stabilization, which better reduces the rotational aspect of a deformity. Finally, in the mid-1990s, thoracoscopic techniques were developed and are currently in use for anterior release and placement of instrumentation. The authors review the major technical developments for the surgical treatment of spinal deformity.

I assemble two rarely used data sets to measure aggregate concentration in the U.S. in the 1980s and 1990s. Despite the merger waves of those decades, aggregate concentration declined in the 1980s and the early 1990s, but rose modestly in the late 1990s. The levels at the end of the decade were at or below the levels of the late 1980s or early 1990s. The average size of firm and the relative importance of larger size classes of firms increased, however. Gini coefficients for employment and payroll shares of companies showed moderate but steady increases from 1988 through 1999.

In late 2011, the Conservative and Liberal Democrat coalition government announced the launch of a new programme on ‘troubled families’ – a term used to describe the estimated 120,000 most behaviourally anti-social families in England and Wales. To many social scientists, this appeared to be yet another reconstruction of the broad ‘underclass’ concept that has run like a thread of analysis through UK poverty discourses over the last 150 years. The symbolic nature and coded meanings of this particular concept of poverty are very interesting, as is the way it has been reconstructed periodically. This paper summarises these reconstructions, and the analytical issues raised by them: the ‘residuum’ concept of the 1880–1914 period; the ‘social problem group’ of the inter-war years; the ‘problem family’ of the 1940s and 1950s; the ‘cycle of deprivation’ of the 1970s; and the ‘underclass’ of the 1980s and 1990s.

Full textAbstract:
The main aim of this study was to analyse fertility change in Ovamboland (North-Central Namibia) (1927–2010) and the Kavango region (North-East Namibia) (1935–1979) in Northern Namibia. According to the results, the fertility change was quite similar in both areas: fertility declined during the 1950s compared to the preceding period, 1935–1949. We can assume that the main reason for this early fertility decline was changes in the number of migrant workers (out-migration), which caused changes in both the marriage age and birth intervals. In both Ovamboland and in the Kavango region, fertility increased from the late 1950s into the early 1960s and the fertility transition started at the end of the 1970s. In both areas, the increase in fertility during thelate 1950s and early 1960s was probably due to the improved health situation. Fertility transition started at the end of the 1970s, but mortality had already started to decline before that. The main causes of this declining fertility at the end of the 1970s and during the 1980s were improved access to modern methods of contraception and probably also the increased level of education. As a result of the HIV epidemic, mortality increased in Ovamboland at the end of the 1990s and early 2000s. The declining fertility in the same period was probably linked to this increased mortality due to AIDS, while the increased fertility after 2008 is, in turn, probably linked to management of the HIV epidemic.

Hebrew authors of the 1960s and 1970s used the biblical context to hint at their protagonists' religious yearnings, to invest their texts with additional levels of meaning, and to amplify the significance of their plots. In the Hebrew “postmodernist” fiction of the late 1980s and the 1990s, however, biblical allusions are less commonly found, and their functions have fundamentally changed. To examine these different functions, let us first juxtapose two novels, Avram Heffner's Allelim [Alleles], a typical example of the “postmodernist” trend, and Amos Oz's Menuha Nekhona [A Perfect Peace], a representative novel of the Israeli “modernist” school.

Full textAbstract:
Why did India merely flirt with nuclear weapons in the 1960s and 1970s only to emerge as a nuclear power in the 1990s? Although a variety of factors informed India's prolonged restraint and subsequent breakthrough, new evidence indicates that India's “nuclear odyssey” can be understood as a function of Indian leaders' ability to secure their country through nonmilitary means, particularly implicit nuclear umbrellas and international institutions. In the 1960s and 1970s, India was relatively successful in this regard as it sought and received implicit support from the superpowers against China. This success, in turn, made acquiring the bomb a less pressing question. At the end of the Cold War, however, nonmilitary measures ceased to be viable for India. In the late 1980s, waning Soviet support and the failure of Rajiv Gandhi's diplomatic initiatives led to the creation of India's de facto nuclear arsenal. In the 1990s, India developed a more overt capability, not simply because the pro-bomb Bharatiya Janata Party came to power, but also because its external backing had vanished and because its efforts to improve its security through diplomacy proved unsuccessful.

Full textAbstract:
This article focuses on the history of Pentecostal and charismatic Christianity in Estonia from the early twentieth century to the early twenty-first century. From the 1870s onwards a series of religious revivals in Estonia created the context for the emergence of the Pentecostal movement in the early twentieth century. Proto-Pentecostalism at the beginning of the century transformed into a fully-fledged Pentecostalism in the 1920s with the involvement of foreign missionaries from Sweden as well as from Finland. The Finnish connection became important in the late 1960s with the emergence of a charismatic Pentecostal revival in the evangelical Christian churches, as well as amongst the Baptists in Tallinn. By the late 1970s the prayer revival had transformed into a healing ministry and this had an impact on the charismatic movement in the Soviet Union. The foreign impact on Pentecostal and charismatic movements in Estonia has also been important from the late 1980s onwards. There has been considerable diversification of the charismatic and Pentecostal traditions in Estonia since the 1990s, and the trends have reflected general changes in charismatic Christianity. Although internally diverse the charismatic Christianity (including the Pentecostals) may well be by now the second largest Protestant tradition in Estonia.

Introduced into China in the late nineteenth century, the bicycle had to compete with a variety of alternative modes of personal transportation that for a number of years limited its appeal and utility. Thus, during the 1920s and 1930s it took a back seat to the hand-pulled rickshaw and during the 1940s to the pedicab (cycle rickshaw). It was only in the 1950s that the bicycle became the primary means of transportation for most urban Chinese. For the next four decades, as its use spread from the city to the countryside, China was the iconic “bicycle kingdom.“ Since the 1990s, however, the pedal-powered bicycle has been overtaken by the automobile (and motorcycle). Nevertheless, with the recent appearance and growing popularity of the e-bike, the bicycle may yet play an important role in China's transport modal mix. This overview history of the bicycle in China is based on a wide range of textual sources in English and Chinese as well as pictorial images.

Since the French "nouvelle vague" of the late 1950s the world cinema has experienced a succession of "waves" which first rolled around some European countries and by blowing up cinematic traditions to this or that extent, led to the birth of the so-called "new cinema" (e.g. in Czechoslovakia or in Germany in the 1960s - 1970s). In Finland the similar process in its local variant occurred in the 1980s. For the most part it was connected with the Kaurismaki brothers' films, primarily with the works of the younger brother, Aki. By the early 1990s he became one of the renowned masters of not only Finnish but the "new European cinema". This article doesn't aspire to give a full detailed analysis of Aki Kaurismaki's film career. Instead, by concentrating on two "polar" films made by this original director, it presents an attempt to line out the range of his creative work and some characteristics of his poetics

Abstract The risk of hepatitis virus transmission from transfusions has declined dramatically from that of the 1940s when posttransfusion hepatitis (PTH) was first appreciated. Introduction of hepatitis B surface antigen screening and conversion to volunteer donors for whole-blood donations in the late 1960s and early 1970s led to substantial reduction in PTH cases. However, up to 10% of the recipients continued to develop PTH, most cases of which were attributed to an unknown non-A, non-B viral agent. Implementation of surrogate marker testing (i.e., alanine aminotransferase and anti-hepatitis B virus core antigen) for residual non-A, non-B hepatitis in the late 1980s reduced the per unit risk of PTH from 1 in 200 to about 1 in 400. Hepatitis C virus was discovered in 1989 and quickly was established as the causative agent of >90% of non-A, non-B PTH. Introduction of progressively improved antibody assays in the early 1990s reduced the risk of PTH due to hepatitis C virus to about 1 in 100 000. Although additional hepatitis viruses exist (e.g., hepatitis G virus), these appear to be minor contributors to clinical PTH, which has been virtually eradicated.

Full textAbstract:
Agriculture in Russia has always had to contend with unfavorable climate. At the same time, large-scale socio-economic experiments have also strained the country’s food production potential throughout the 20th century. The relative role of climate and state agricultural policies in affecting production of cereals was studied for the period of 1958–2010. The study used statistical yield modeling to explain the variations in observed yields with slowly changing progress in technology and management and weather variability. The correlation between the actual and weather-explained yields is moderate to high: measured at the level of the entire country, Pearson’s r is 0.74 and Spearman’s rho is 0.68. Further, we suggest that the residual yield variability can be explained partially with the influence of large-scale changes in agricultural policies at the state level. Between these policies, we consider the following key periods in the history of Russian agriculture: “Virgin Lands” campaign (end of 1950s), Kosygin-Liberman initiatives (late 1960s), Brezhnev’s investment programmes in response of stagnation of agriculture (late 1970s – early 1980s), Gorbachev’s “Perestrojka” (1985–1991), and land privatization and price liberalization (1990s).

Long-term changes in coastal zoobenthos in the northern Baltic Sea: the role of abiotic environmental factors – ICES Journal of Marine Science, 70: 440–451. We investigated site-specific changes in a coastal zoobenthic community during 1964–2007 in the northern Baltic Sea. Multivariate analysis indicated that the community structure had changed. The amphipods Monoporeia affinis and Pontoporeia femorata decreased drastically in the late 1970s–early 1980s, and by the early 1990s P. femorata vanished and M. affinis abundance was low. The decline of M. affinis and P. femorata was followed by an increase of the bivalve Macoma balthica and the arrival of the polychaete genus Marenzelleria in the 1990s. Trend analyses showed a rising trend for near-bottom temperature from the late 1960s. There was a significant decline in salinity during the early 1980s, which stabilized during the early 1990s. A negative trend was observed for oxygen concentration during the entire study period. There were interannual variations in the phosphorus and nitrogen concentrations, and a step-like increase in phosphorus concentration at the beginning of the 21st century. The correlations of temperature, salinity, oxygen, total phosphorus and nitrogen with zoobenthic communities were examined using Constrained Correspondence Analysis. Temperature was the most highly correlated explanatory variable for the benthic species. The study highlights the importance of long-term data sets in assessing the state and ecological processes of zoobenthic systems.

Abstract Since the beginning of the 1990s in Korea, the category and definition of new generation literature have become the topic of heated debate. One may understand this tendency as ‘generation severance’, ‘alienation between social classes’, or the ‘consumption-oriented culture of the masses’. Here, we call the literary youth born in approximately 1960 ‘the new generation’. In literature, the new generation refers to the appearance of a new culture and way of thinking. This generation passed their childhood in the 1970s and faced no such great difficulties as their parents combating poverty. However, they grew up under the indirect influence of a dark political outlook and suppression. Generally, they have a great affection for the culture produced by mass media. If we compare their development process with the literary stream in Korea, the 1960s could be defined as the era of literature for independence and strong self-awareness, the 1970s as the era for people, the 1980s as the era for the rights or emancipation of labour, and the 1990s as the era of new generation literature. Meanwhile, the appearance of the ‘Korean Wave’, or so-called ‘Hallyu’, has become one of the most beloved popular cultural phenomena both in Asia and in other countries since the late 1990s.

Abstract. Southeast Australia (SEA) experienced a protracted drought during the mid-1990s until early 2010 (known as the Big Dry or Millennium Drought) that resulted in serious environmental, social and economic effects. This paper analyses a range of historical climate data sets to place the recent drought into context in terms of Southern Hemisphere inter-annual to multi-decadal hydroclimatic variability. The findings indicate that the recent Big Dry in SEA is in fact linked to the widespread Southern Hemisphere climate shift towards drier conditions that began in the mid-1970s. However, it is shown that this link is masked because the large-scale climate drivers responsible for drying in other regions of the mid-latitudes since the mid-1970s did not have the same effect on SEA during the mid- to late 1980s and early 1990s. More specifically, smaller-scale synoptic processes resulted in elevated autumn and winter rainfall (a crucial period for SEA hydrology) during the mid- to late 1980s and early 1990s, which punctuated the longer-term drying. From the mid-1990s to 2010 the frequency of the synoptic processes associated with elevated autumn/winter rainfall decreased, resulting in a return to drier than average conditions and the onset of the Big Dry. The findings presented in this paper have marked implications for water management and climate attribution studies in SEA, in particular for understanding and dealing with "baseline" (i.e. current) hydroclimatic risks.

Abstract Sjare, B., and Stenson, G. B. 2010. Changes in the reproductive parameters of female harp seals (Pagophilus groenlandicus) in the Northwest Atlantic. – ICES Journal of Marine Science, 67: 304–315. Changes in female harp seal (Pagophilus groenlandicus) reproductive parameters from 1980 to 2004, and long-term trends since the early 1950s, are evaluated. Estimates of the total number of seals in the Northwest Atlantic declined from ∼3.0 million in the 1950s to 1.8 million in the early 1970s, then increased steadily to 5.5 million in 1996, at which relatively stable level it has remained since. Pregnancy rates increased from ∼86% in the 1950s to a high of 98% in the mid-1960s, then declined to ∼65–70% by the early 1990s; the rate then varied between 45 and 70% from 2000 to 2004. Concurrently, the mean age at sexual maturity decreased from 5.8 (s.e = 0.02) years in the mid-1950s to 4.1 (s.e. = 0.02) in the late 1970s, increased to 5.5 (s.e. = 0.03) years by the early 1990s, and peaked at 5.7 (s.e. = 0.01) in 1995. From 2000 to 2004, mean age varied from 4.9 (s.e. = 0.01) to 6.0 (s.e. = 0.01) years. Although the direction of change in each of the parameters was consistent with a density-dependent response, changes in population size explained relatively little of the variability observed, suggesting that other ecological or environmental factors were influential.

We employed data envelopment analysis (DEA) to examine the technical and scale efficiency of the sawmill industry of Washington State. We found that there is regional variation in the rate of technical efficiency and that for most years the industry in aggregate operated at a point of modest scale inefficiency. In addition, we examined the industry's rate of productivity growth and technical change between the early 1970s and late 1990s using the Malmquist input-oriented productivity index. We found that the industry experienced a modest average annual decline in productivity and technical change during the 1970s, but experienced strong productivity growth and technical change during the 1980s and 1990s.

The focus of this paper is on the earlier, recent and future developments in closing the water circuits in pulp and paper production. During the 1960s the U.S. pulp and paper industry was in its environmental infancy concentrating mainly on removal of settleable solids and initiating river assimilative capacity studies. The 1970s began with environmental legislation having enforceable powers to achieve primary and secondary (biological) treatment which was fundamentally fulfilled during the 1980s. The late 1980s and early 1990s opened with toxicity becoming the major environmental issue as measured mainly by absorbable organic halogens (AOX) and dioxins. This paper identifies progress and key technological developments towards furthering stringent environmental enhancement and provides additional knowledge requirements leading into the next century.

AbstractThis article analyses Frank Ankersmit’s Dutch-language writings in the context of Dutch debates on historical theory. In the 1970s and 1980s historical theory became a flourishing discipline in the Netherlands; it was a compulsory part of all history programmes in the country, and all history departments employed one or more historical theorists. The Dutch theoretical debates of the 1970s and 1980s mainly dealt with the relation between history and the social sciences. In these debates Ankersmit defended the traditional historicist conception of historiography, while developing philosophical views that would remain important in his later work. Especially relevant in this respect is his critique of linguistic transcendentalism. This view is already present in his earliest writings in the 1970s, but it also informs his work on historical representation of the late 1980s and 1990s, and it is very important in his analysis of historical experience, which has its roots in his Dutch writings of the mid-1990s.

Abstract This paper analyzes the difference in taxpayers’s attitudes toward fiscal politics during the 1970s - early 1980s, a period dominated by «taxpayer revolt», and those observed in the late 1990s, when taxpayers show an apparent state of apathy. The answer is that taxpayers where unhappy in the late 1970s and early 1980s because their effective real incomes were being reduced in a period of stagnant growth with inflation. They remained quiescent in the last years because taxes are extracted from them during a period of real income growth and low inflation. Paradoxically, the economic reforms that the earlier tax revolt set off may have generated the real growth that has made die ultimate failure of the movement emerge.

Abstract. A large number of glaciers in the Tibetan Plateau (TP) have experienced wastage in recent decades. And the wastage is different from region to region, even from glacier to glacier. A better understanding of long-term glacier variations and their linkage with climate variability requires extending the presently observed records. Here we present the first tree-ring-based glacier mass balance (MB) reconstruction in the TP, performed at the Hailuogou Glacier in southeastern TP during 1868–2007. The reconstructed MB is characterized mainly by ablation over the past 140 yr, and typical melting periods occurred in 1910s–1920s, 1930s–1960s, 1970s–1980s, and the last 20 yr. After the 1900s, only a few short periods (i.e., 1920s–1930s, the 1960s and the late 1980s) were characterized by accumulation. These variations can be validated by the terminus retreat velocity of Hailuogou Glacier and the ice-core accumulation rate in Guliya and respond well to regional and Northern Hemisphere temperature anomaly. In addition, the reconstructed MB is significantly and negatively correlated with August–September all-India monsoon rainfall (AIR) (r1871-2008 = −0.342, p < 0.0001). These results suggest that temperature variability is the dominant factor for the long-term MB variation at the Hailuogou Glacier. Indian summer monsoon precipitation does not affect the MB variation, yet the significant negative correlation between the MB and the AIR implies the positive effect of summer heating of the TP on Indian summer monsoon precipitation.

Full textAbstract:
This paper explores the medicalization-of-science-news thesis. Considering the results from surveys and media analyses, biomedical news appears to be the current core of the public representation of science. Why is this the case? A historical approach may bring us one step closer to an answer. A longitudinal analysis of science in the press demonstrates a shift in the core representation of science in the 1930s, and again in the 1980s/1990s, a trend change in the late 1960s, and the assimilation of science reportage to the rhetoric of biomedical news. The physical sciences provided the main source of social imagination during an unlikely intermezzo between the early 1930s and the early 1980s. Two speculations on this long-term shift are developed: (a) the medicalization of modern society may explain the recent shift, and (b) the resistance function of social representations of science may explain the long-term change.

10516 Background: Therapy for medulloblastoma and primitive neuroectodermal tumor has evolved from surgery and adjuvant radiotherapy to risk-adapted multimodal regimens. The impact of these changes in treatment on long-term outcomes remains unknown. Methods: Cumulative incidence of late mortality ( > 5 years from diagnosis), subsequent malignant neoplasms (SMN), chronic health conditions and psychosocial functioning were evaluated among 5-year survivors in CCSS diagnosed between 1970 and 1999. Survivors were stratified according to treatment decade (1970s, 1980s, 1990s) and treatment exposure (surgery + craniospinal irradiation [CSI] ≥30 Gy, no chemotherapy; surgery + CSI ≥30 Gy + chemotherapy [high-risk therapy], surgery + CSI ˂30 Gy + chemotherapy [standard-risk therapy]). Rate ratios (RRs), odds ratios (ORs) and 95% confidence intervals (CIs) were estimated for long-term outcomes among treatment eras and exposure groups using multivariable piecewise-exponential models. Results: Among 1,380 eligible survivors (median [range] age 29 [6-20] years; 21.4 [5-44] years from diagnosis), the 15-year cumulative incidence of all-cause (21.9% 1970s vs. 12.8% 1990s; p = 0.003) and recurrence-related (16.2% vs 9.6%, p = 0.03) late mortality decreased with no reduction in mortality attributable to late effects of therapy including SMN. Among 959 participants, the incidence of SMN did not decrease by era or by treatment group. However, survivors treated in the 1990s had an increased cumulative incidence of severe, life-threatening and fatal health conditions (16.9% 1970s vs 25.4% 1990s; p = 0.03), and were more likely to develop multiple severe or life-threatening health conditions, RR = 2.98 (95% CI, 1.10-8.07). Survivors of standard-risk therapy were less likely to use special education services than high-risk therapy patients, OR = 0.51 (95% CI, 0.33-0.78). Conclusions: Historical changes in therapy have improved 5-year survival, reduced risk of late mortality due to disease recurrence, and reduced special education utilization, at the cost of increased risk for multiple, severe and life-threatening chronic health conditions.

Full textAbstract:
The study continues a series of observations started in the late 1950s, aimed at inferring changes in the Lake Ladoga ecosystem state recorded in the surface-sediment diatom assemblages. At the pre-anthropogenic stage (prior to the 1960s), the composition of the surface-sediment diatom assemblages indicated an oligotrophic state of Lake Ladoga. With the increased P load to the lake (late 1960s–1980s), the transition to a mesotrophic state was recorded via increased proportions of eutrophic species and decreased abundances of the taxa typical of the pre-anthropogenic stage. In the early 1990s, the composition of the surface-sediment diatom assemblages still indicated a mesotrophic state despite a decreased external P load. At the present de-eutrophication stage of Lake Ladoga (the 2000s), the abundances of eutrophic taxa steadily decrease while some taxa typical of the pre-anthropogenic period return to their dominating position in the surface-sediment diatom assemblages. However, despite the decreased P concentrations, the Lake Ladoga ecosystem has not returned to its pre-anthropogenic state as indicated by the present-day composition of the surface-sediment diatom assemblages. This suggests a delayed ecosystem response to the decreased anthropogenic pressure, and possibly some irreversible changes resulting from the eutrophication. At present, de-eutrophication processes and ecosystem recovery are superimposed upon the recent climatic changes that govern the onset and duration of the vegetative seasons for the phytoplankton communities in Lake Ladoga. The diatom-inferred changes in the ecological state of Lake Ladoga are in agreement with the results of longterm hydrochemical and hydrobiological studies.

Full textAbstract:
Abstract An interannual seesaw between the intensities of the Icelandic and Aleutian lows and its impact on surface climate observed during the twentieth century are investigated. In a recent period from the late 1960s to the early 1990s, their seesaw relationship was particularly apparent in late winter. The associated anomalies in surface air temperature were significant in many regions over the extratropical Northern Hemisphere except in central portions of the continents. The seesaw also modified the ocean–atmosphere exchange of heat and moisture extensively over the North Atlantic and North Pacific by changing evaporation and precipitation. Since the seesaw formation was triggered by eastward propagation of stationary Rossby wave trains from the North Pacific into the North Atlantic, anomalous circulation over the North Pacific in January was identified as a good precursor for February surface air temperatures in the Euro–Atlantic sector during that period. The seesaw relationship between the two lows underwent multidecadal modulations during the twentieth century. It was weak in the mid-1950s through the mid-1960s, while it was particularly strong during the preceding period from the 1920s to the 1940s with its impact on surface temperatures as extensive as in the recent period. Although it reached maturity in January, the precursory signal of the seesaw in that early period was also found in the North Pacific one month earlier, which suggests that the formation was through essentially the same mechanisms as in the recent period.

Full textAbstract:
This article explores the ways in which architecture, landscape design, and site planning helped maintain racial segregation in housing in Atlanta, Georgia, between the 1960s and 1990s. Under Jim Crow, apartment complexes in Atlanta hewed to national design norms. By the late 1960s, however, racial tension, rioting, and passage of the Fair Housing Act led to proliferation of the architecture of enclosure: design that helped code communities as white through pastoral symbolism and heavy, obscuring landscaping. The concept, which appeared to a lesser degree in other U.S. housing markets, was introduced to Atlanta at Riverbend (1966-1972), a swinging-singles complex developed in part by Dallas’s Trammell Crow with a site plan by California’s Lawrence Halprin & Associates. The practice was generalized in the 1970s and 1980s by Post Properties, which became one of the region’s largest builders.

Evidence from Current Population Surveys, various cohorts of the National Longitudinal Surveys, and the Panel Study of Income Dynamics suggests that the fraction of American employees who were paid salaries held constant from the late 1960s through the late 1970s, and continued to hold constant or perhaps fell slightly thereafter through the late 1990s. An analysis that accounts for the changing industrial, occupational, demographic, and economic structure of the work force shows that this fraction was 9 percentage points below what would have been expected in the late 1970s. This shortfall is not explained by growth in the temporary help industry, declining unionization, institutional changes in overtime or wage payment regulation, the increasing openness of American labor and product markets, or convergence of nonwage aspects of hourly and salaried employment. The author suggests several alternative explanations.

Full textAbstract:
Arctic charr in Lake Ronvatn, a mountain lake in southern Norway was re-established through stocking. The population went extinction during the early 1980s due to acidification, when the lake was highly acidified with a mean pH of 5.2-5.4 with occasional declines to 4.3-4.7. However, from the mid to late 1990s, the pH and acid-neutralising capacity (ANC) of the lake rose to 5.8-5.9 and 13-15 µeq L-1, respectively. The lake is extremely dilute with a mean conductivity and calcium concentration of 7.7 µS cm-1 and 0.35 mg L-1, respectively. The lake was stocked with 250 Arctic charr from a neighbouring lake between 1998 and 2000. These introductions were highly successful, as test-fishing in 2004, 2008 and 2012 revealed a relatively dense population of Arctic charr, and the presence of several young age groups. Water quality has remained stable since the late 1990s, or has slightly improved.
