The relationship between the robustness of HRV derived by linear and nonlinear methods to the required minimum data lengths has yet to be well understood. The normal electrocardiography (ECG) data of 14 healthy volunteers were applied to 34 HRV measures using various data lengths, and compared with the most prolonged (2000 R peaks or 750 s) by using the Mann–Whitney U test, to determine the 0.05 level of significance. We found that SDNN, RMSSD, pNN50, normalized LF, the ratio of LF and HF, and SD1 of the Poincaré plot could be adequately computed by small data size (60–100 R peaks). In addition, parameters of RQA did not show any significant differences among 60 and 750 s. However, longer data length (1000 R peaks) is recommended to calculate most other measures. The DFA and Lyapunov exponent might require an even longer data length to show robust results. Conclusions: Our work suggests the optimal minimum data sizes for different HRV measures which can potentially improve the efficiency and save the time and effort for both patients and medical care providers.

Well-functioning financial markets can have a positive effect on economic growth by facilitating savings and more efficient allocation of capital. This paper characterises some of the recent theoretical developments that analyse the relationship between financial intermediation and economic growth and presents empirical estimates based on a model of the linkage between financially intermediated investment and growth for two separate groups of countries, developing and advanced. Empirical estimates for both groups suggest that financial intermediation through the efficiency of investment leads to a higher rate of growth per capita. The relevant coefficient estimates show a higher level of significance for the developing countries. This financial liberalisation in the form of deregulation and establishment and development of stock markets can be expected to lead to enhanced economic growth.

Objective: The need to make sense of coherence in placement support for student dental hygienists has been shown. On this basis, this study investigated the relationship between the sense of coherence of student dental hygienists and their view of the profession and attitude to work in order to clarify how they perceive their prospects for employment. Methods: The subjects were graduation-year students at all of the dental hygienist training institutions in Japan, and anonymous, self-administered questionnaires were sent to the institutions by post in 2019. The results were analyzed by χ2 tests, as well as one-way analysis of variance and multiple comparisons using Tukey’s test, with the level of significance set at 5%. Results: Of 6270 questionnaires that were returned, 6264 were analyzed. The sense of coherence (SOC) component senses were manageability (F(26,221) = 5306.06, p < 0.01), meaningfulness (F(26,222) = 4373.48, p < 0.01), and comprehensibility (F(26,216) = 3986.12, p < 0.01), with meaningfulness scoring significantly higher than the other two (p < 0.01). Analysis with SOC scores divided into the low, medium, and high groups showed a relationship between the SOC of student dental hygienists and their view of the profession and attitude to work (p < 0.01), such that higher SOC scores were associated with a better view of the profession and a better attitude to work (F(26,225) = 282.18, p < 0.01). Conclusions: The results suggest that education that increases SOC in dental hygienist training programs may positively affect future prospects for student dental hygienists.

The Relationship

The objective of this study was to explore and empirically investigate the relationship between the labour force across educational levels and foreign direct investment (FDI), and to facilitate comparisons of education statistics and indicators across countries based on uniform and internationally agreed definitions. The analysis focuses on OECD countries. The empirical findings suggest that an educated labour force positively affects inward FDI. However, different educational levels do not have the same level of significance; tertiary education appears to have the greatest influence. As far as gender is concerned, the level of female participation in the workforce seems to be crucial in attracting FDI, and governments should therefore adopt policies to promote women’s empowerment.

Recent efforts to “engineer” new nonlinear optical materials with specific desired characteristics has engendered a need for a theoretical description of optical properties which is readily accessible to chemists, yet correctly treats the essential physics of dielectric response. This paper describes a simple empirical molecular orbital model which gives useful insights into the relationship between chemical composition, crystalline structure, and optical susceptibilities. We compare the probabilities of finding new harmonic generators in various chemical classes. Rigorous bounds on the magnitudes of linear and nonlinear optical coefficients and their anisotropies are also discussed.

Knowledge management and continuous improvement are key success factors that are applied in organizations independently; However, there is a significant relationship between the two, therefore organizations that seek to be leaders in their sector must analyze them together. Considering that universities have a leading role and must transcend the expectations of our society, I have considered it pertinent to carry out this article whose purpose is to establish the relationship between Knowledge Management and Continuous Improvement in a Private University from Lima, Peru. It has a quantitative approach because statistical analysis was used to test what was established in the hypotheses. The design is non-experimental, cross-sectional, since information is presented as it occurs in reality and in a given time, it is transectional, correlational, because it measures and evaluates the relationship between the variables. The sample is made up of 45 individuals between heads of areas and school coordinators, to whom a questionnaire with 32 questions was applied, whose data were processed in the statistical program SPSS version 25. Finally, the significant relationship between management of the knowledge and continuous improvement, obtaining a Spearman Rho, 0.730, at the 1% level of significance. Likewise, the findings affirm that the phases of creating, storing, applying and transferring knowledge also have a significant relationship with continuous improvement.

The research aims to study the relationship between the management strategies of the small projects of the workers in their dimensions: (Project phase strategy, making decisions, the project management strategy of financial production, Marketing Productive Management Strategy, the strategy of managing productive legal projects) with satisfaction with life dimensions: (Psychological compatibility, Self-compliance, Work environment, and Social compatibility) . The research sample consisted of 102 persons working in four small projects, "Ceramics - Bamboo - Serma - Hand Carpets". They were selected in a pesky-purpose manner from the employees of these projects in Sakiet Abu Shaara village, Sentris, Menoufia Governorate and 10th of Ramadan City. "General data form", "Project Management Strategies scale", and "measure of satisfaction with life" were applied. The study followed the descriptive and analytical approach. The data were categorized and analyzed using appropriate statistical methods through the SPSS statistical program such as number and percentages, arithmetic mean, standard deviation, T-test, Pearson correlation coefficient, Chi-square and F-test. The most important results are related to the relationship between the project management strategy and the financial productivity and self-compliance at the level of significance of 0.01, which means that the realization of the requirements of the project in terms of finance and meet the needs, resulting in self-compatibility.  There is also a correlation between the project management strategy and the business environment at the level of 0.01 meaning that whenever the project needs to be met in terms of funding and meet the needs of the project as this leads to compatibility with the place of residence of the project and the surrounding environment, there is an inverse correlation Between the social situation and the decision-making at the level of significance of 0.01, which means that the greater the number of employees are married the less ability to make the decisions needed in those small projects, which means the impact of the ability to make decisions on the social situation of the individual. There were statistically significant differences between the averages of the different projects in terms of the overall project management strategy according to the dwelling. The highest value was for the medium in the ceramics project and the lowest in the hand carpets where the ceramic represents the highest average 2.000 while the carpets represent the lowest average by 1.809 at the level of significance 0.1. There were significant differences between the mean of the various projects in terms of satisfaction with total life according to the dimension of psychological compatibility and the highest value for the average in the hand carpet project where the results showed that the average and standard deviation of hand carpets is (23.745 ± 4.38) The recommendations of the government, decision-makers and ministries to establish a culture of entrepreneurship and motivate young people to set up private projects through the media, paying attention to the enactment of laws on small projects to motivate young people to establish and develop small and micro enterprises, In various stages to ensure the success and continuity of the project.

Abstract Background: Diversity sensitive task perception and diversity sensitive behavioural intentions are strong predictors of diversity sensitive care. Nevertheless, it has been less clear which psychosocial determinants are affecting these concepts in health care providers. This article also explores whether there are differences in relationships between these concepts, and how these concepts are interrelated. The study focussed on the following psychosocial determinants: (a) ethnocentric attitudes and (b) intercultural capabilities. The latter concept is drawn from the four-dimensional construct of intercultural intelligence. Methods: A survey was conducted in a health care student population (N = 364). In addition to classic survey questions, behavioural intentions were measured through the use of eight vignettes comprising situations characterised by diversity in health care. Results: Regression analyses show that ethnocentric attitudes were negatively associated with diversity sensitive task perception and behavioural intentions. Interestingly, we found no significant relationship between cognitive intercultural capabilities (IC) and diversity sensitivity. Motivational- and behavioural intercultural capabilities were significantly associated with diversity sensitive task perception and behavioural intentions. Motivational IC had a stronger relationship with task perception. Behavioural IC had a stronger relationship with behavioural intentions. Adding diversity sensitive task perception in a supplementary regression model as an independent variable on behavioural intentions caused a shift in associations. The significant association between motivational IC and behavioural intentions disappeared, and a significant association between diversity sensitive task perception and diversity sensitive behavioural intention appeared. Conclusion: Diversity education should increasingly focus on diminishing ethnocentric attitudes and encouraging behavioural IC and motivational IC in health care students. The paper also suggests two theoretical hypothesises. Firstly, metacognitive IC is a concept strongly related to two IC: motivational IC and behavioural IC. Secondly, the relationship between motivational IC and behavioural intentions is fully mediated by diversity sensitive task perception. Further research that substantiate these theoretical hypothesises is recommended.

AbstractGiven an ageing population and increased participation by women in the labour force, the relationship between unpaid care and the availability of women to the labour force is gaining in importance as an issue. This article assesses the impact of unpaid care on transitions into employment by women aged between 45 and 59 years. It uses the German Socio-Economic Panel (SOEP) from the years 2001–2014 to estimate Cox regression models for 6,201 employed women. The results indicate that women with higher caring responsibilities and women with lower caring responsibilities are heterogeneous in terms of the socio-economic characteristics that they exhibit: higher-intensity care providers tend to have a lower level of educational attainment and a weaker attachment to the labour force than women with less-intensive caring responsibilities. Furthermore, while women with more-intensive caring roles are highly likely to exit the labour market altogether, female carers with less-intensive roles seem to be able to combine work and care better. These results highlight the importance of providing more affordable institutional and professional care services, especially for low- and medium-income families.
