Billboard magazine has been keeping track of the 100 hottest (most popular) songs of the year since 1958. Lists of the Hot 100 titles from 1960 to 2019 (6001 titles) were used to study the way in which popular song titles changed over time. Based on significant polynomial regression trends and significant results from a discriminant function analysis, it is concluded that there were three main phases in titles (early, middle, and late) and that these phases differ in predictable manners in terms of stylistic features such as length, abstraction, activity, and the use of the word “love”. Early phase titles are longer, more concrete, more passive, and they do not use the word “love” often; middle phase titles are of medium length, more abstract, of medium activation, and use the word “love” frequently. Titles of the last phase are shorter, more concrete, more active, and do not often employ the word love. A possible factor contributing to these differences is the rise in popularity of rock and roll and hip-hop respectively and their different periods of ascendency.

The research reported in this article seeks to understand how and why individuals are appointed to serve as executive heads of international organizations. A simple statement of the behavioral rule used in selection of executive heads is developed in the form of an executive head appointment function. The type of data available for the analysis of the appointment of executive heads in international organizations is identified, and an empirical examination of changes in emphasis in the selection of executive heads is reported. The executive head appointment function utilized in the study views appointment as an executive head as a function of six factors (three organizational, one national, and two personal). Discriminant function analysis is used to determine if the function would distinguish between individuals appointed during the period 1945–57 and those appointed from 1958–70 as executive heads in UN treaty-based organizations. It is possible to distinguish, on the basis of the specified executive head appointment function, between executive heads appointed during the two halves of the time period under study. It is therefore reasonable to conclude that the emphasis involved in the selection of executive heads has changed over time in UN treaty-based organizations.

Data taken from the blood of 262 patients diagnosed for malabsorption, elective cholecystectomy, acute cholecystitis, infectious hepatitis, liver cirrhosis, or chronic renal disease were analyzed with three numerical taxonomy (NT) methods : cluster analysis, principal components analysis, and discriminant function analysis. Principal components analysis revealed discrete clusters of patients suffering from chronic renal disease, liver cirrhosis, and infectious hepatitis, which could be displayed by NT clustering as well as by plotting, but other disease groups were poorly defined. Sharper resolution of the same disease groups was attained by discriminant function analysis.

While there have been a number of studies on the decontextualisation and secularisation of traditional ritual music in America, Taiwan and other parts of the globe, very little has been written on the processes and transformations that South Africa’s indigenous ceremonial songs go through over time. This study was prompted by the authors’ interest in, and engagement with the Xhosa initiation song Somagwaza, which has been re-imagined as a popular song, but has also purportedly found its way into other religious spaces. In this article, we attempted to investigate the extent to which the song Somagwaza is still associated with the Xhosa initiation ritual and to analyse evidence of it being decontextualised and secularised in contemporary South Africa. Our methodology included an examination of the various academic treatments of the song, an analysis of the lyrics of a popular song, bearing the same name, holding small focus group discussions, and distributing questionnaires to speakers of isiXhosa on the topic of the song. The data gathered were analysed using the constant comparative method of analysing qualitative research.

This study is the first step towards more systematic monitoring of urban bat fauna in Vietnam and other Southeast Asian countries by collecting bat echolocation call parameters in Ho Chi Minh and Tra Vinh cities. We captured urban bats and then recorded echolocation calls after releasing in a tent. Additional bat’s echolocation calls from the free-flying bats were recorded at the site where we captured bat. We used the obtained echolocation call parameters for a discriminant function analysis to test the accuracy of classifying these species based on their echolocation call parameters. Data from this pilot work revealed a low level of diversity for the studied bat assemblages. Additionally, the discriminant function analysis successfully classified bats to four bat species with an accuracy of >87.4%. On average, species assignments were correct for all calls from Taphozous melanopogon (100% success rate), for 70% of calls from Pipistrellus javanicus, for 80.8% of calls from Myotis hasseltii and 67.3% of calls from Scotophilus kuhlii. Our study comprises the first quantitative description of echolocation call parameters for urban bats of Vietnam. The success in classifying urban bats based on their echolocation call parameters provides a promising baseline for monitoring the effect of urbanization on bat assemblages in Vietnam and potentially also other Southeast Asian countries.

SummaryObjective. To identify clinically useful predictors of adherence to medication among persons with schizophrenia. Method. We evaluated levels of compliance with neuroleptic medication among 32 consecutive admissions with DSM-III-R schizophrenia from a geographically defined catchment area using a compliance interview. We also assessed symptomatology, insight, neurological status and memory. Results. Less than 25% of consecutive admissions reported being fully compliant. Drug attitudes were the best predictor of regular compliance, symptomatology the best predictor of noncompliance, and memory the best predictor of partial compliance with neuroleptic medication. Conclusions. These data emphasise the complexity of factors that influence whether a person adheres to his medication regimen. Furthermore, they suggest that these factors may vary within the same person over time.

The magnetite composition from three sets of samples of Mazama, St. Helens set Y, and Bridge River tephras from Jasper and Banff national parks are used to test whether discriminant function analysis can unambiguously distinguish these tephras. The multivariate method is found to be very sensitive to the change in reference samples. St. Helens set Y tephra is clearly distinguished. However, discrimination between Mazama and Bridge River tephras is less distinct. A set of unknown tephras from the Sunwapta Pass area was used to test the classification schemes. Unknown tephras are assigned to different tephra types depending on which reference tephra set is used in the discriminant function analysis.
