A reasonable strategy for reducing road casualties should reside in safety engineering: seat-belts; airbags; ABS brakes; water-repellent road-surfaces; and the like. Yet, for some time there have been rumblings about whether engineering initiatives are ever effective over the long term. One crucial issue that has emerged concerns the interpretation of trends in casualty rates; the present article is directed primarily to this issue and, specifically, to what appears to be a paradox in the relationship between death and injury statistics.

One of the central concepts of The Polish Peasant in Europe and America, especially highlighted in the “Methodological Note,” is the relationship between values and attitudes which frames the subsequent empirical analyses and conclusions. The aim of the present article is to reconstruct Florian Znaniecki’s early idea of values in order to demonstrate its originality and later influence on his sociological contributions. As the author argues, Znaniecki’s early insights with regard to values allow us to reconsider his collaboration with William Thomas and to interpret The Polish Peasant as a part of Znaniecki’s long-term research programme.

Introduction. Road traffic collisions and injuries are a global public health issue, not only due to high mortality rates, but also due to significant multiple injuries and subsequent disabilities. The number of deaths and injuries from road traffic collisions in Latvia is still significantly higher than in other European Union countries. Given the current paradigm that views road traffic injuries as predictable and avoidable, the development of an evidence–based and cross–sectoral understanding of individual habits and related factors is essential for the successful implementation of road safety improvement measures in the long term. The aim of the study was to describe persons killed or seriously injured in road traffic collisions and their risk factors from 2010 to 2018, to study the road safety habits of the adult population of Latvia during the same period, as well as to clarify the relationship between the habits and individual factors, health behaviour, and attitude towards road safety factors. Material and methods. The research has been carried out in parallel in two stages. In the first stage of the study, The Statistical Database of Road Traffic Collisions and Consequences was used for the analysis, including data on 57,471 persons involved in road traffic collisions. In the second stage of the study, using the data of a representative cross–sectional study of “Health Behaviour among Latvian Adult Population”, road safety habits – the use of reflectors, the use of seat belts in the front and rear seats – were analysed. The study tool was a validated, standardised questionnaire, including data from 10,731 respondents. Frequency distribution, cross–tabulation analysis, and Chi–square (?2) test were used for processing statistical data. Odds ratio, Spearman’s rank correlation coefficient, and multiple logistic regression were used to assess the associations. Results. Between 2010 and 2018, the percentage of persons killed or seriously injured in road traffic collisions has decreased on average by 0.3 percentage points per year, while the incidence rate of persons killed or seriously injured in road traffic collisions per 100,000 person–years has increased on average by 1.2% per year. Higher odds of being fatally or seriously injured in road traffic collisions are observed in males, among the elderly (55 years and older) and the youngest (18 to 24 years) persons, when the collision occurs on regional and local roads, and in other cities compared to Riga, as well as in persons with exceeded permitted blood alcohol concentration level. During the period from 2010 to 2018, the use of reflectors in Latvia has not changed significantly (p > 0.05), in general, they are almost always worn by 53.6% of respondents. The use of seat belts has increased slightly – from 93.5% to 95.6% in the front seat of the vehicle, from 52.4% to 56.3% in the rear seat of the vehicle (p < 0,001). The multifactor regression analysis shows that lower odds for road safety habits are observed in males, among the youngest age group (18–24 years), in respondents with primary education,as well as among residents of Riga, followed by other cities compared to rural areas. Better road safety habits are among respondents without excessive alcohol consumption (OR = 1,6 – 2,1 depending on the habit analysed), among nonsmokers (OR = 1,5 – 1,8) and those with families where smoking is not allowed in the car (OR = 1,3 – 1,7). The odds for safe road habits are higher among persons who have visited their family doctor during the last year (OR = 1,2 – 1,3). Individuals with a possitive attitude towards the use of seat belts (OR = 1,9 – 9,7 depending on the specific question) and penalties for traffic violations (OR = 1,3 – 1,9) have higher odds for road safety habits. Higher odds of wearing seat belts are among respondents with more responsible attitude towards driving under the influence of alcohol (OR = 1,8 – 2,8) and respect for speed limits (OR = 1,3 – 1,9). Conclusions. Road safety and individual habits are a pressing public health issue in Latvia. Although the proportion of persons killed or seriously injured in road traffic collisions is decreasing, the incidence rate of persons killed or seriously injured in road traffic collisions (per 100,000 person–years) is increasing. The use of seat belts in the front seat of the vehicle is gradually approaching the level of other European countries, while the use of seat belts in the rear seat of the vehicle and the use of reflectors is insufficient and critically low. The relationship between individual road safety habits has been demonstrated not only with demographic, socio–economic, and attitude factors but also with careless health behaviour, which highlights the need to base sectoral policies and research in the long term on an integrated approach and cross–sectoral cooperation.

SummaryIn a collaborative trial of eleven laboratories which was performed mainly within the framework of the European Community Bureau of Reference (BCR), a second reference material for thromboplastin, rabbit, plain, was calibrated against its predecessor RBT/79. This second reference material (coded CRM 149R) has a mean International Sensitivity Index (ISI) of 1.343 with a standard error of the mean of 0.035. The standard error of the ISI was determined by combination of the standard errors of the ISI of RBT/79 and the slope of the calibration line in this trial.The BCR reference material for thromboplastin, human, plain (coded BCT/099) was also included in this trial for assessment of the long-term stability of the relationship with RBT/79. The results indicated that this relationship has not changed over a period of 8 years. The interlaboratory variation of the slope of the relationship between CRM 149R and RBT/79 was significantly lower than the variation of the slope of the relationship between BCT/099 and RBT/79. In addition to the manual technique, a semi-automatic coagulometer according to Schnitger & Gross was used to determine prothrombin times with CRM 149R. The mean ISI of CRM 149R was not affected by replacement of the manual technique by this particular coagulometer.Two lyophilized plasmas were included in this trial. The mean slope of relationship between RBT/79 and CRM 149R based on the two lyophilized plasmas was the same as the corresponding slope based on fresh plasmas. Tlowever, the mean slope of relationship between RBT/79 and BCT/099 based on the two lyophilized plasmas was 4.9% higher than the mean slope based on fresh plasmas. Thus, the use of these lyophilized plasmas induced a small but significant bias in the slope of relationship between these thromboplastins of different species.

This paper aims to detect the impact of firm managers’ risk attitude on the relationship between the degree of output market uncertainty and firm investment. The findings show that there is a negative relationship between these two aspects for risk-averse managers while there is a positive relationship for risk-loving ones, since they have different utility functions. Based on the findings, this paper proposes recommendations for firm managers to take into account when making investment decisions and long-term business strategies as well.

This epilogue argues that Castile was solvent throughout Philip II's reign. A complex web of contractual obligations designed to ensure repayment governed the relationship between the king and his bankers. The same contracts allowed great flexibility for both the Crown and bankers when liquidity was tight. The risk of potential defaults was not a surprise; their likelihood was priced into the loan contracts. As a consequence, virtually every banking family turned a profit over the long term, while the king benefited from their services to run the largest empire that had yet existed. The epilogue then looks at the economic history version of Spain's Black Legend. The economic history version of the Black Legend emerged from a combination of two narratives: a rich historical tradition analyzing the decline of Spain as an economic and military power from the seventeenth century onward, combined with new institutional analysis highlighting the unconstrained power of the monarch.

: Neurological diseases bring great mental and physical torture to the patients, and have long-term and sustained negative effects on families and society. The attention to neurological diseases is increasing, and the improvement of the material level is accompanied by an increase in the demand for mental level. The p75 neurotrophin receptor (p75NTR) is a low-affinity neurotrophin receptor and involved in diverse and pleiotropic effects in the developmental and adult central nervous system (CNS). Since neurological diseases are usually accompanied by the regression of memory, the pathogenesis of p75NTR also activates and inhibits other signaling pathways, which has a serious impact on the learning and memory of patients. The results of studies shown that p75NTR is associated with LTP/LTD-induced synaptic enhancement and inhibition, suggest that p75NTR may be involved in the progression of synaptic plasticity. And its pro-apoptotic effect is associated with activation of proBDNF and inhibition of proNGF, and TrkA/p75NTR imbalance leads to pro-survival or pro-apoptotic phenomena. It can be inferred that p75NTR mediates apoptosis in the hippocampus and amygdale, which may affect learning and memory behavior. This article mainly discusses the relationship between p75NTR and learning memory and associated mechanisms, which may provide some new ideas for the treatment of neurological diseases.

This chapter explores the interactions between economic growth and human development, as measured by the Human Development Index, theoretically and empirically. Drawing on many studies it explores the links in two chains, from economic growth to human development, and from human development to growth. Econometric analysis establishes strong links between economic growth and human development, and intervening variables influencing the strength of the chains. Because of the complementary relationship, putting emphasis on economic growth alone is not a long-term viable strategy, as growth is likely to be impeded by failure on human development. The chapter classifies country performance in four ways: virtuous cycles where both growth and human development are successful; vicious cycles where both are weak; and lopsided ones where the economy is strong but human development is weak, or conversely ones where human development is strong but the economy is weak.

Northeast India is situated at the nexus of the South Asian, Southeast Asian, and East Asian biogeographical realms and harbours diverse biota, providing a unique opportunity to archaeologists and anthropologists for the study of the relationship between humans and their environment over the ages. Moreover, this region, the abode of diverse ethnic groups with diverse cultures and customs, hints at a long history of continuous and close association between humans and nature, which is important in the understanding of plant and animal domestication. Genetic analysis of present-day domesticates with their wild counterparts provides valuable insights into their differentiation, time of domestication, and changes in their morphological traits through control by humans. The chapter also elucidates the role played by rice in Northeast Indian culture and highlights the long-term history of rice agriculture in the region.
