Abstract Compact torus (CT) injection is one of the most promising methods for the central fuelling of next-generation reactor-grade fusion devices due to its high density, high velocity, and self-contained magnetised structure. A newly compact torus injector (CTI) device in Keda Torus eXperiment (KTX), named KTX-CTI, was successfully developed and tested at the University of Science and Technology in China. In this study, first, we briefly introduce the basic principles and structure of KTX-CTI, and then, present an accurate circuit model that relies on nonlinear regression analysis (NRA) for studying the current waveform of the formation region. The current waveform, displacement, and velocity of CT plasma in the acceleration region are calculated using this NRA-based one-dimensional point model. The agreement between the model results and the experimental results is better than in the previous general model results estimated by the device dimensions in previous. The next-step upgrading reference scheme of the KTX-CTI device is preliminarily investigated using this NRA-based point model. This research can provide insights for the development of experiments and future upgrades of the device.

We have shown previously that isotope-labelled nucleotides in human metaphase chromosomes can be detected and mapped by imaging secondary ion mass spectrometry (SIMS), using the University of Chicago high resolution scanning ion microprobe (UC SIM). These early studies, conducted with BrdU- and 14C-thymidine-labelled chromosomes via detection of the Br and 28CN- (14C14N-> labelcarrying signals, provided some evidence for the condensation of the label into banding patterns along the chromatids (SIMS bands) reminiscent of the well known Q- and G-bands obtained by conventional staining methods for optical microscopy. The potential of this technique has been greatly enhanced by the recent upgrade of the UC SIM, now coupled to a high performance magnetic sector mass spectrometer in lieu of the previous RF quadrupole mass filter. The high transmission of the new spectrometer improves the SIMS analytical sensitivity of the microprobe better than a hundredfold, overcoming most of the previous imaging limitations resulting from low count statistics.

The relation between authoritarianism and social dominance orientation was analyzed, with authoritarianism measured using a three-dimensional scale. The implicit multidimensional structure (authoritarian submission, conventionalism, authoritarian aggression) of Altemeyer’s (1981, 1988) conceptualization of authoritarianism is inconsistent with its one-dimensional methodological operationalization. The dimensionality of authoritarianism was investigated using confirmatory factor analysis in a sample of 713 university students. As hypothesized, the three-factor model fit the data significantly better than the one-factor model. Regression analyses revealed that only authoritarian aggression was related to social dominance orientation. That is, only intolerance of deviance was related to high social dominance, whereas submissiveness was not.

We examine the effectiveness and sustainability of the distance teacher education program established by the University of Education, Winneba, Ghana, by investigating the differences in the academic performance of students who are trained in the teacher education program via traditional and distance education modes, respectively, from 2011 to 2015. Close attention is paid to the factors that affect the academic performance of students in the distance mode. Our findings confirm that traditional mode students perform better than their distance mode counterparts in terms of cumulative GPAs. Gender and economic demographics of distance study centers are found to affect the academic performance of distance education students significantly. The policy implications of these findings are discussed and directions of further action are outlined.

Abstract Professional literature and practice started to focus intensively on the field of talent management. A lack of talented individuals occurred in all sectors worldwide. The war for talents has not faded out, on the contrary, it has been intensifying. The aim of the paper is therefore to analyse the perception of opportunities for development and management of talents in forestry and to specify characteristics of employee/ talent support perception in surveyed companies. The analysis is based on a primary survey conducted in 101 forestry companies. The data were obtained through surveys in which one manager and one employee represented a single company. One-dimensional and multidimensional statistics were used to evaluate the data. The results showed that employees perceived developmental conditions in companies more positively than what was stated by managers and company representatives. The average difference in the perception was 8.5%; employees perceived the conditions better than company representatives. When negative phenomena were analysed, the perception was quite opposite. The average difference was 9.5%. The limit of the paper is the narrow focus on primary sector companies. The results may help surveyed companies in the primary sector to encourage managers and employees to participate in developmental programmes as their own initiative and willingness to take part in education and developmental activities was found.

Over half of all students enrolling at a particular university in KwaZulu-Natal fail to complete a degree. This article is wanting to determine to what extent the marks they obtain for English and Mathematics at school impact on their probability of graduation at this university. In addressing this problem, other student specific factors associated with their gender, race and the type of school they have attended need also to be properly accounted for. To provide answers for this study, the performance of 24 392 students enrolling at the university over the period 2004 to 2012 was followed until they graduated or dropped out from their studies. A structural equation model was fitted because it allows one to separate a direct effect from that of an indirect effect. Gender, race and school background were found to be very significant with males, Black Africans and students coming from a less privileged school background having a smaller probability associated with eventually graduating from this university. Males tend to perform better than females in Mathematics, with females performing better males in English. More importantly, however, a single percentage point increase in one’s mark for English increases the probability associated with graduating from this university far more than would be the case if their Mathematics mark were to increase by a single percentage point. In the light of these mediated results, perhaps this university should be directing their efforts more towards improving the English (rather than mathematical) literacy of students entering the university.

Coromandel Coast

At the beginning of the 17th century, the Danish East India company (Dansk Østindisk Kompagni) was established in Europe. In particular, Tranquebar (Dansborg fortress) became the stronghold of the Danes in India. In another hundred years, at the very beginning of the 18th century, the first Lutheran missionaries appeared on the Coromandel coast. At this time the Danish Royal mission was established in Tranquebar, funded by king Frederick IV. It consisted mainly of Germans who graduated from the University of the Saxon city of Halle. Those missionaries not only actively preached among the local population, but also studied languages of the region, translated Gospels into local languages and then published it in the printing house they created. They also trained neophytes from among the local children. One of the first missionaries in Tranquebar was pastor Bartholomäus Ziegenbalg, who lived in India from 1706 to 1719. Information about Pastor's activities in the Royal Danish mission has been preserved in his letters and records. These letters and papers were regularly printed in Halle in the reports of the Royal Danish Mission («Ausführliche Berichte an, die von der königlichen dänischen Missionaren aus Ost-Indien»). However, besides letters and reports, this edition constantly published texts of a special kind, called «conversations» (das Gespräch). They looked like dialogues between pastor Bartholomäus Ziegenbalg and local religious authorities. Those brahmans explained the basic principles of the Hindu religion, and their opponent showed them the absurdity of their creed by comparing it with the main tenets of Christianity. The following is a translation of one of these dialogues.
