The Relationship

An on-site system for measuring low-frequency noise and complainant's responses to the low-frequency noise was developed to confirm whether the complainant suffer from the environmental noise with low-frequency components. The system suggests several methods to find the dominant frequency and major sound pressure level spectrum of the noise causing annoyance. This method can also yield a quantified relationship (correlation coefficient and percentage of response to the noise) between physical noise properties and the complainant’s responses. The advantage of this system is that it can easily find the relationship between the complainant’s response to the acoustic event of the houses and the physical characteristics of the low-frequency noise, such as the time trends and frequency characteristics. This paper describes the developed system and provides an example of the measurement results.

AbstractSurvey nonresponse may increase the chances of nonresponse error, and different interviewers contribute differentially to nonresponse. This article first addresses the relationship between initial impressions of interviewers in survey introductions and the outcome of these introductions, and then contrasts this relationship with current viewpoints and practices in telephone interviewing. The first study described here exposed judges to excerpts of interviewer speech from actual survey introductions and asked them to rate twelve characteristics of the interviewer. Impressions of positive traits such as friendliness and confidence had no association with the actual outcome of the call, while higher ratings of “scriptedness” predicted lower participation likelihood. At the same time, a second study among individuals responsible for training telephone interviewers found that when training interviewers, sounding natural or unscripted during a survey introduction is not emphasized. This article concludes with recommendations for practice and further research.

The new anthropometric history, which blends human biology with history and economics in a form understandable to a general audience, began in the mid-1970s with the study of important questions about American slavery, such as the age of slaves at menarche and their first birth, stature attained relative to other contemporary populations, time trends in stature, and the relationship between mortality and physical growth in childhood. This chapter updates the literature based on refinements in the methodology and on substantially more evidence from slave manifests. Important new conclusions concern childbearing at young ages, adequacy of the diet, the profitability of childhood stunting and recovery, and the cognitive and socioeconomic consequences of severe early childhood deprivation.

In order to determine the relationship between age and achievement in the politico-military domain, the reigns of 25 long-tenured European absolute monarchs were - analyzed as cross-sectional time series of 238 5-year age periods. Both linear and curvilinear age functions were defined along with variables to control for individual differences, linear time trends, and other potential artifacts. A partial correlation analysis indicated that leader age tends to be negatively correlated with military success in foreign wars and with treaty negotiation, and positively correlated with civil instability at home, whether in the royal family or in the populace. Moreover, some indicators of military and diplomatic success are curvilinear inverted U-functions of leader age, the peak approximately occurring in the leader's 42nd year.

The Relationship

Background and Purpose: Hypertensive disorders of pregnancy (HDP) comprise 4 subtypes. Previous studies have not investigated the relationship between stroke risk, different HDP subtypes, and follow-up time, which was the purpose of this study. Methods: Data of 17 588 women aged 18 to 45 years who had a history of HDP in Taiwan from 2000 to 2017 was retrospectively reviewed. After matching with confounders, 13 617 HDP women and 54 468 non-HDP women were recruited. Results: HDP women had an adjusted hazard ratio (aHR) of 1.71 (95% CI, 1.46−2.00) for stroke, and 1.60 (1.35−1.89) and 2.98 (2.13−4.18) for ischemic and hemorrhagic stroke, respectively ( P <0.001 for all). The overall stroke risk in the HDP group was still 2.04 times 10 to 15 years after childbirth (1.47−2.83, P <0.001). Although the risks of both ischemic and hemorrhagic stroke persisted, their risk time trends were different. The risk of ischemic stroke reached peak during 1 to 3 years after childbirth with an aHR of 2.14 (1.36–3.38), while hemorrhagic stroke risk gradually increased and had an aHR of 4.64 (2.47−8.73) after 10 to 15 years of childbirth (both P <0.001). Among the 4 HDP subtypes, chronic hypertension with superimposed preeclampsia had the highest stroke risk (aHR=3.86, 1.91−7.82, P <0.001), followed by preeclampsia–eclampsia (aHR=2.00, 1.63−2.45, P <0.001), and gestational hypertension (aHR=1.68, 1.13−2.52, P <0.05); chronic preexisting hypertension had the lowest stroke risk (aHR=1.27, 0.97−1.68, P >0.05). Furthermore, multiple HDP combined with preeclampsia had aHR of 5.48 (1.14−26.42, P <0.05). Conclusions: The effect of HDP on the risk of future stroke persisted for up to 17 years, both for ischemic and hemorrhagic strokes. The presence of multiple HDP and preeclampsia further increase the stroke risk.

A review is given of information on the galactic-centre region obtained from recent observations of the 21-cm line from neutral hydrogen, the 18-cm group of OH lines, a hydrogen recombination line at 6 cm wavelength, and the continuum emission from ionized hydrogen.Both inward and outward motions are important in this region, in addition to rotation. Several types of observation indicate the presence of material in features inclined to the galactic plane. The relationship between the H and OH concentrations is not yet clear, but a rough picture of the central region can be proposed.

Biologic Factors

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.
