Bone mineral density (BMD) is the most widely used predictor of fracture risk. We performed the largest meta-analysis to date on lumbar spine and femoral neck BMD, including 17 genome-wide association studies and 32,961 individuals of European and east Asian ancestry. We tested the top BMD-associated markers for replication in 50,933 independent subjects and for association with risk of low-trauma fracture in 31,016 individuals with a history of fracture (cases) and 102,444 controls. We identified 56 loci (32 new) associated with BMD at genome-wide significance (P < 5 × 10−8). Several of these factors cluster within the RANK-RANKL-OPG, mesenchymal stem cell differentiation, endochondral ossification and Wnt signaling pathways. However, we also discovered loci that were localized to genes not known to have a role in bone biology. Fourteen BMD-associated loci were also associated with fracture risk (P < 5 × 10−4, Bonferroni corrected), of which six reached P < 5 × 10−8, including at 18p11.21 (FAM210A), 7q21.3 (SLC25A13), 11q13.2 (LRP5), 4q22.1 (MEPE), 2p16.2 (SPTBN1) and 10q21.1 (DKK1). These findings shed light on the genetic architecture and pathophysiological mechanisms underlying BMD variation and fracture susceptibility.

Background The Global Burden of Disease Study 2013 (GBD 2013) aims to bring together all available epidemiological data using a coherent measurement framework, standardised estimation methods, and transparent data sources to enable comparisons of health loss over time and across causes, age–sex groups, and countries. The GBD can be used to generate summary measures such as disability-adjusted life-years (DALYs) and healthy life expectancy (HALE) that make possible comparative assessments of broad epidemiological patterns across countries and time. These summary measures can also be used to quantify the component of variation in epidemiology that is related to sociodemographic development. Methods We used the published GBD 2013 data for age-specific mortality, years of life lost due to premature mortality (YLLs), and years lived with disability (YLDs) to calculate DALYs and HALE for 1990, 1995, 2000, 2005, 2010, and 2013 for 188 countries. We calculated HALE using the Sullivan method; 95% uncertainty intervals (UIs) represent uncertainty in age-specific death rates and YLDs per person for each country, age, sex, and year. We estimated DALYs for 306 causes for each country as the sum of YLLs and YLDs; 95% UIs represent uncertainty in YLL and YLD rates. We quantified patterns of the epidemiological transition with a composite indicator of sociodemographic status, which we constructed from income per person, average years of schooling after age 15 years, and the total fertility rate and mean age of the population. We applied hierarchical regression to DALY rates by cause across countries to decompose variance related to the sociodemographic status variable, country, and time. Findings Worldwide, from 1990 to 2013, life expectancy at birth rose by 6·2 years (95% UI 5·6–6·6), from 65·3 years (65·0–65·6) in 1990 to 71·5 years (71·0–71·9) in 2013, HALE at birth rose by 5·4 years (4·9–5·8), from 56·9 years (54·5–59·1) to 62·3 years (59·7–64·8), total DALYs fell by 3·6% (0·3–7·4), and age-standardised DALY rates per 100 000 people fell by 26·7% (24·6–29·1). For communicable, maternal, neonatal, and nutritional disorders, global DALY numbers, crude rates, and age-standardised rates have all declined between 1990 and 2013, whereas for non–communicable diseases, global DALYs have been increasing, DALY rates have remained nearly constant, and age-standardised DALY rates declined during the same period. From 2005 to 2013, the number of DALYs increased for most specific non-communicable diseases, including cardiovascular diseases and neoplasms, in addition to dengue, food-borne trematodes, and leishmaniasis; DALYs decreased for nearly all other causes. By 2013, the five leading causes of DALYs were ischaemic heart disease, lower respiratory infections, cerebrovascular disease, low back and neck pain, and road injuries. Sociodemographic status explained more than 50% of the variance between countries and over time for diarrhoea, lower respiratory infections, and other common infectious diseases; maternal disorders; neonatal disorders; nutritional deficiencies; other communicable, maternal, neonatal, and nutritional diseases; musculoskeletal disorders; and other non-communicable diseases. However, sociodemographic status explained less than 10% of the variance in DALY rates for cardiovascular diseases; chronic respiratory diseases; cirrhosis; diabetes, urogenital, blood, and endocrine diseases; unintentional injuries; and self-harm and interpersonal violence. Predictably, increased sociodemographic status was associated with a shift in burden from YLLs to YLDs, driven by declines in YLLs and increases in YLDs from musculoskeletal disorders, neurological disorders, and mental and substance use disorders. In most country-specific estimates, the increase in life expectancy was greater than that in HALE. Leading causes of DALYs are highly variable across countries. Interpretation Global health is improving. Population growth and ageing have driven up numbers of DALYs, but crude rates have remained relatively constant, showing that progress in health does not mean fewer demands on health systems. The notion of an epidemiological transition—in which increasing sociodemographic status brings structured change in disease burden—is useful, but there is tremendous variation in burden of disease that is not associated with sociodemographic status. This further underscores the need for country-specific assessments of DALYs and HALE to appropriately inform health policy decisions and attendant actions.

Background The Global Burden of Disease, Injuries, and Risk Factor study 2013 (GBD 2013) is the first of a series of annual updates of the GBD. Risk factor quantification, particularly of modifiable risk factors, can help to identify emerging threats to population health and opportunities for prevention. The GBD 2013 provides a timely opportunity to update the comparative risk assessment with new data for exposure, relative risks, and evidence on the appropriate counterfactual risk distribution. Methods Attributable deaths, years of life lost, years lived with disability, and disability-adjusted life-years (DALYs) have been estimated for 79 risks or clusters of risks using the GBD 2010 methods. Risk–outcome pairs meeting explicit evidence criteria were assessed for 188 countries for the period 1990–2013 by age and sex using three inputs: risk exposure, relative risks, and the theoretical minimum risk exposure level (TMREL). Risks are organised into a hierarchy with blocks of behavioural, environmental and occupational, and metabolic risks at the first level of the hierarchy. The next level in the hierarchy includes nine clusters of related risks and two individual risks, with more detail provided at levels 3 and 4 of the hierarchy. Compared with GBD 2010, six new risk factors have been added: handwashing practices, occupational exposure to trichloroethylene, childhood wasting, childhood stunting, unsafe sex, and low glomerular filtration rate. For most risks, data for exposure were synthesised with a Bayesian meta-regression method, DisMod-MR 2.0, or spatial-temporal Gaussian process regression. Relative risks were based on meta-regressions of published cohort and intervention studies. Attributable burden for clusters of risks and all risks combined took into account evidence on the mediation of some risks such as high body-mass index (BMI) through other risks such as high systolic blood pressure and high cholesterol. Findings All risks combined account for 57·2% (95% uncertainty interval [UI] 55·8–58·5) of deaths and 41·6% (40·1–43·0) of DALYs. Risks quantified account for 87·9% (86·5–89·3) of cardiovascular disease DALYs, ranging to a low of 0% for neonatal disorders and neglected tropical diseases and malaria. In terms of global DALYs in 2013, six risks or clusters of risks each caused more than 5% of DALYs: dietary risks accounting for 11·3 million deaths and 241·4 million DALYs, high systolic blood pressure for 10·4 million deaths and 208·1 million DALYs, child and maternal malnutrition for 1·7 million deaths and 176·9 million DALYs, tobacco smoke for 6·1 million deaths and 143·5 million DALYs, air pollution for 5·5 million deaths and 141·5 million DALYs, and high BMI for 4·4 million deaths and 134·0 million DALYs. Risk factor patterns vary across regions and countries and with time. In sub-Saharan Africa, the leading risk factors are child and maternal malnutrition, unsafe sex, and unsafe water, sanitation, and handwashing. In women, in nearly all countries in the Americas, north Africa, and the Middle East, and in many other high-income countries, high BMI is the leading risk factor, with high systolic blood pressure as the leading risk in most of Central and Eastern Europe and south and east Asia. For men, high systolic blood pressure or tobacco use are the leading risks in nearly all high-income countries, in north Africa and the Middle East, Europe, and Asia. For men and women, unsafe sex is the leading risk in a corridor from Kenya to South Africa. Interpretation Behavioural, environmental and occupational, and metabolic risks can explain half of global mortality and more than one-third of global DALYs providing many opportunities for prevention. Of the larger risks, the attributable burden of high BMI has increased in the past 23 years. In view of the prominence of behavioural risk factors, behavioural and social science research on interventions for these risks should be strengthened. Many prevention and primary care policy options are available now to act on key risks.

Background Genome-wide association studies have identified multiple genetic variants associated with prostate cancer risk which explain a substantial proportion of familial relative risk. These variants can be used to stratify individuals by their risk of prostate cancer. Methods We genotyped 25 prostate cancer susceptibility loci in 40,414 individuals and derived a polygenic risk score (PRS).We estimated empirical odds ratios (OR) for prostate cancer associated with different risk strata defined by PRS and derived agespecific absolute risks of developing prostate cancer by PRS stratum and family history. Results The prostate cancer risk for men in the top 1% of the PRS distribution was 30.6 (95% CI, 16.4-57.3) fold compared with men in the bottom 1%, and 4.2 (95% CI, 3.2-5.5) fold compared with the median risk. The absolute risk of prostate cancer by age of 85 years was 65.8% for a man with family history in the top 1% of the PRS distribution, compared with 3.7% for a man in the bottom 1%. The PRS was only weakly correlated with serum PSA level (correlation = 0.09). Conclusions Risk profiling can identify men at substantially increased or reduced risk of prostate cancer. The effect size, measured by OR per unit PRS, was higher in men at younger ages and in men with family history of prostate cancer. Incorporating additional newly identified loci into a PRS should improve the predictive value of risk profiles. Impact:We demonstrate that the risk profiling based on SNPs can identify men at substantially increased or reduced risk that could have useful implications for targeted prevention and screening programs.

Jean-Jacques Rousseau’s Émile, ou de I’Education (Émile, or on Education) has been described by Rousseau scholars in latter twentieth century English-language philosophy as an educational classic. In 1995 Robert Wokler argued that together with Montesquieu, Hume, Smith, and Kant among his contemporaries, Rousseau had exerted the most profound influence on modern European intellectual history, “perhaps even surpassing anyone else of his day." For Wokler Émile is “the most significant work on education after Plato’s Republic.” Earlier in 1977, Allan Bloom questioned why Émile had not been the subject of analysis in philosophy relative to the rest of Rousseau‘s work, for “Émile is truly a great book, one that lays out for the first time and with the greatest clarity and vitality the modern way of posing the problems of psychology.” Bloom also saw Émile as “one of those rare total or synoptic books... a book comparable to Plato’s Republic, which it is meant to rival or supersede” and argued that Rousseau himself was at the source of a new tradition: “Whatever else Rousseau may have accomplished, he presented alternatives available to man more comprehensively and profoundly and articulated them in the form which has dominated discussion since his time." Even Peter Gay’s earlier commentary on John Locke and education in 1964 could not escape this central positioning of the text. The significance of Locke’s Some Thoughts on Education is weighed in relation to its impact on Rousseau‘s Émile. For Gay, the latter is “probably the most influential revolutionary tract on education that we have.”

From Steely Nation-State Superman to Conciliator of Economical Global Empire – A Psychohistory of Finnish Police Culture 1930-1997 My study concerns the way police culture has changed within the societal changes in Finnish society between 1930 and 1997. The method of my study was psycho-historical and post-structural analysis. The research was conducted by examining the psycho-historical plateaus traceable within Finnish police culture. I made a social diagnosis of the autopoietic relationship between the power-holders of Finnish society and the police (at various levels of hierarchical organization). According to police researcher John P. Crank, police culture should be understood as the cognitive processes behind the actions of the police. Among these processes are the values, beliefs, rituals, customs and advice which standardize their work and the common sense of policemen. According to Crank, police culture is defined by a mindset which thinks, judges and acts according to its evaluations filtered by its own preliminary comprehension. Police culture consists of all the unsaid assumptions of being a policeman, the organizational structures of police, official policies, unofficial ways of behaviour, forms of arrest, procedures of practice and different kinds of training habits, attitudes towards suspects and citizens, and also possible corruption. Police culture channels its members’ feelings and emotions. Crank says that police culture can be seen in how policemen express their feelings. He advises police researchers to ask themselves how it feels to be a member of the police. Ethos has been described as a communal frame for thought that guides one’s actions. According to sociologist Martti Grönfors, the Finnish mentality of the Protestant ethic is accentuated among Finnish policemen. The concept of ethos expresses very well the self-made mentality as an ethical tension which prevails in police work between communal belonging and individual freedom of choice. However, it is significant that it is a matter of the quality of relationships, and that the relationship is always tied to the context of the cultural history of dealing with one’s anxiety. According to criminologist Clifford Shearing, the values of police culture act as subterranean processes of the maintenance of social power in society. Policemen have been called microcosmic mediators, or street corner politicians. Robert Reiner argues that at the level of self-comprehension, policemen disparage the dimension of politics in their work. Reiner points out that all relationships which hold a dimension of power are political. Police culture has also been called a canteen culture. This idea expresses the day-to-day basis of the mentality of taking care of business which policing produces as a necessity for dealing with everyday hardships. According to police researcher Timo Korander, this figurative expression embodies the nature of police culture as a crew culture which is partly hidden from police chiefs who are at a different level. This multitude of standpoints depicts the diversity of police cultures. According to Reiner, one should not see police culture as one monolithic whole; instead one should assess it as the interplay of individuals negotiating with their environment and societal power networks. The cases analyzed formed different plateaus of study. The first plateau was the so-called ‘Rovaniemi arson’ case in the summer of 1930. The second plateau consisted of the examinations of alleged police assaults towards the Communists during the Finnish Continuation War of 1941 to 1944 and the threats that societal change after the war posed to Finnish Society. The third plateau was thematic. Here I investigated how using force towards police clients has changed culturally from the 1930s to the 1980s. The fourth plateau concerned with the material produced by the Security Police detectives traced the interaction between Soviet KGB agents and Finnish politicians during the long 1970s. The fifth plateau of larger changes in Finnish police culture then occurred during the 1980s as an aftermath of the former decade. The last, sixth plateau of changing relationships between policing and the national logic of action can be seen in the murder of two policemen in the autumn of 1997. My study shows that police culture has transformed from a “stone cold” steely fixed identity towards a more relational identity that tries to solve problems by negotiating with clients instead of using excessive force. However, in this process of change there is a traceable paradox in Finnish policing and police culture. On the one hand, policemen have, at the practical level, constructed their policing identity by protecting their inner self in their organizational role at work against the projections of anger and fear in society. On the other hand, however, they have had to safeguard themselves at the emotional level against the predominance of this same organizational role. Because of this dilemma they must simultaneously construct both a distance from their own role as police officers and the role of the police itself. This makes the task of policing susceptible to the political pressures of society. In an era of globalization, and after the heyday of the welfare state, this can produce heightened challenges for Finnish police culture.

Opinnäytetyöni tarkastelee eurooppalaisen kulttuurin kannalta keskeistä kommunikaatiovälinettä, painettua kirjaa, ja sen kansainvälistä luonnetta ja liikkumista. Teemaan perehdytään helsinkiläisen Gustaf Otto Waseniuksen (1789-1852) kirjakaupan toiminnan avulla keskittyen tarkastelemaan ulkomaisen kirjallisuuden tuomista Suomeen 1800-luvun alkupuolella. Tutkielma käsittelee ensisijaisesti itse kauppiastoimintaa: mitä kirjakauppayhteyksiä Waseniuksella oli sekä miten ja keiden ehdoilla ne toimivat. Näiden kysymysten ohessa pohdin myös itse kirjojen välityksellä tapahtunutta tiedonvälitystä. Työn tavoitteena on paljastaa, minkälaisia suomalaisten kirjakauppiaiden ja lukijoiden kirjallisuudenhankinnan sekä lukemisen kontekstit ja resurssit olivat 1800-luvun alkupuolella. Tutkielman lähteinä on käytetty Waseniuksen kirjakaupan kirjeitä ja kuitteja sekä sensuuriviranomaisten arkistoja. Tutkielmani jakautuu kolmeen osaan. Ensiksi paneudun Waseniuksen kauppaverkoston syntyyn ja sen esittelyyn: Waseniuksen kansainväliset yhteydet keskittyivät kolmelle kulttuurialueelle. Ruotsista hän sai kirjoja kaikilta merkittäviltä kustantajilta, kauppiailta sekä itsenäisesti toimivilta kirjailijoilta. Saksankielisen kulttuurin tarjontaa Wasenius pystyi hankkimaan Leipzigin kansainvälisten kirjakauppiaiden avulla. Ranskalaisen kirjallisuuden osalta Wasenius omasi toimivat yhteydet Pariisin kirjakauppiaisiin. Sen sijaan Brittein saaret jäivät vielä Waseniuksen kontaktiverkoston ulkopuolelle, samoin myös Pietarin huomattava kulttuurikeskus. Tämän jälkeen keskityn yhteyksien toimintaan. Wasenius solmi kauppakumppaniensa kanssa yleiseurooppalaisen komissionääri-sopimuksen, jonka valtuuttamana hän sai myydä kunkin ulkomaisen kauppiaan tuotteita liikkeessään. Ensiksi tarkastelen kauppiaiden välisten etäisyyksien ylittämistä. Aikakauden kuljetustavat huomioonottaen suuret etäisyydet eivät Waseniuksen kirjojen hankintaa juuri haitanneet, vaan suurkauppiaana hän pystyi käyttämään aikansa parhaat resurssit lähetystensä kuljettamiseen. Toiseksi pohdin aikakauden kauppiastoimintojen ja kulttuuripiirteiden vaikutusta kirjakauppaan. Waseniuksen toiminta kirjakauppiaana perustui taloudellisen voiton tavoittelulle, mikä tarkoitti mm. sitä, että lähetysten sisältö määrättiin etukäteen hyvin tarkasti. Ennen Suomeen saapumistaan kirjoilla piti olla varma ostaja, minkä Wasenius useimmiten varmisti ennakkotilausluetteloin ja etumaksuin. Kolmanneksi esiin nousevat 1800-luvun alun poliittiset tapahtumat, jotka osaltaan, kauppiaan silmiin kaikkein näkyvimmin, vaikuttivat kirjojen tuontiin. Sensuurin piti periaatteessa estää useiden satojen vaarallisena pidetyn kirjan levittäminen ja lukeminen Suomessa, mutta Wasenius ei suinkaan lopettanut kiellettyjen kirjojen tuontia, vaan salakuljetti sensuroitavia teoksia jatkuvasti liikkeeseensä myytäväksi. Suomalaiset viranomaiset hyväksyivät usein tämänkaltaisen toiminnan, joten venäläistä sensuuriasetusta tai hallintoa ei juuri kunnioitettu. Vertailu eurooppalaiseen kirjakauppatoimintaan osoittaa Waseniuksen omanneen erittäin hyvät kansainväliset suhteet. Tämä kuitenkin johtui niin kirjakauppatoiminnan keskittymisestä harvojen kauppiaiden käsiin kuin myös oman kustannustoiminnan vähyydestä. Tiedonvälityksen kehityksen ja kulttuurihistorian kannalta Waseniuksen kansainvälinen toiminta osoittautuu noudattelevan vielä vanhan eliittikulttuurin muotoja, mutta kirjakauppainstituution kehittyminen aivan uudenlaiseen kukoistukseen valmisteli jo kansallisen kulttuurin nousemista lähivuosikymmeninä.

The genetic population structure of red snapper Lutjanus malabaricus and Lutjanus erythropterus in eastern Indonesia and northern Australia was investigated by allozyme electrophoresis and sequence variation in the control region of mtDNA. Samples were collected from eight sites in Indonesia and four sites in northern Australia for both species. A total of 13 allozyme loci were scored. More variable loci were observed in L. malabaricus than in L. erythropterus. Sequence variation in the control region (left domain) of the mitochondrial genome was assessed by RFLP and direct sequencing. MtDNA haplotype diversity was high (L. erythropterus, 0.95 and L. malabaricus, 0.97), as was intraspecific sequence divergence, (L. erythropterus, 0.0-12.5% and L. malabaricus, 0.0-9.5%). The pattern of mtDNA haplotype frequencies grouped both species into two broad fisheries stocks with a genetic boundary either between Kupang and Sape (L. malabaricus) or between Kupang and Australian Timor Sea (L. erythropertus). The allozyme analyses revealed similar boundaries for L. erythropterus. Seven allozymes stocks compared to two mtDNA stocks of L. malabaricus including Ambon, which was not sampled with mtDNA, however, were reported. Possible reasons for differences in discrimination between the methods include: i) increased power of multiple allozyme loci over the single mtDNA locus, ii) insufficient gene sampling in the mtDNA control region and iii) relative evolutionary dynamics of nuclear (allozyme loci) and mitochondrial DNA in these taxa. Allozyme and haplotype data did not distinguish separate stocks among the four Australian locations nor the central Indonesian (Bali and Sape locations) for both L. malabaricus and L. erythropterus.

The aim of this study is to explore by systematic textual analysis the crucial conceptions of constructive alignment and to reconstruct the concept of constructive alignment and examine the relation between conceptual relationships in John Biggs’s texts. In this study, I have also analyzed the presuppositions of the concept of constructive alignment and its possible implications. The research material includes Biggs’s (1996b; 2003) article entitled Enhancing Teaching through Constructive Alignment and book entitled Teaching for Quality Learning at University. The primary purpose of the systematic textual analysis is to reconstruct concepts and gain access to a new or more profound understanding of the concepts. The main purpose of the constructive alignment is to design a teaching system that supports and encourages students to adopt a deep approach learning. At the center of the constructive alignment are two concepts: constructivism in learning and alignment in teaching. A tension was detected between these concepts. Biggs assumes that students’ learning activities are primed by the teaching. Because of this it is not important what the teacher does. At the same time he emphasizes that teaching interacts with learning. The teacher’s task is to support student’s appropriate learning activities. On the basis of the analysis, I conclude these conceptions are not mutually exclusive. Interaction between teaching and learning has an effect on student’s learning activities. The most essential benefit of the model of constructive alignment is that Biggs brings together and considers teaching at the same level with learning. A weakness of Biggs’s model relates to the theoretical basis and positions of the concept of constructive alignment. There are some conflicts between conceptions of epistemology in Biggs’s texts. In addition, Biggs writes about constructivism also as conceptions of epistemology, but doesn’t consider implications of that position or what follows or doesn’t follow from that commitment. On the basis of the analysis, I suggest that constructivism refers in Biggs’s texts rather to constructivism in learning than philosophical constructivism. In light of this study, constructive alignment doesn´t lead to philosophical constructivism. That’s why constructive alignment stays out of idealism. Biggs’s way of thinking about teachers possibility to confronting students’ misconceptions and evaluate and assess students’ constructions support a realist purpose in terms of philosophical stance. Realism does not drift toward general problems of relativism, like lack of criteria for assessing or evaluate these constructions.
