The method adopted by Mr. Fearn in dealing with the above subject in the February number of the Journal is open to many serious objections. To begin with, it is at best approximate and as Mr. Farren points out in his article in the March number, Mr. Fearn's approximation, although near enough for displacements, give on double differentiation less close approximation for acceleration. And for less regular motions than in the case under discussion the approximation to the acceleration by Mr. Fearn's method might be comparatively poor.The greatest objection which the writer has to Mr. Fearn's method is that it is far too intricate and cumbersome. It unnecessarily involves mathematics of a high order when the problem can be solved by means within the compass of any first year student of engineering.Mr. Farren's method, on the other hand, is of extreme simplicity and as a graphical method could hardly be improved upon. But there is a very simple-analytical solution and one moreover of the familiar type for the ordinary nonarticulated case.

In order to evaluate the factor structure of the Emotions Profile Index (EPI) 217 first-year students accommodated in the school?s dormitory were examined. The data was analyzed with Beelzebub algorithm for comparative confirmative and exploratory component analysis. The results show that the empirical structure of EPI can be related with 4 bipolar factor structure proposed in the scoring key, although the relation is far from indubitable. The structure of hypothetical dimension Distrustful vs. Trustful has a solid empirical foundation, correlations between orthoblique and hypothetical factors of theoretical dimensions Gregarious vs. Depressed and Timid vs. Aggressive are acceptable while, on the other hand, the structure of the hypothetical dimension Controlled vs. Dyscontrolled requires revising, not only because the Adventurous trait is used to describe both of their poles but for numerous other reasons. The paper suggests a few ways of improving the characteristics of the test.

The dual aim of this article is, on the one hand, to identify Bessarabian writers’ individual and group rationale to stay in the territory occupied by the Soviet authorities after 28 June 1940 and, on the other hand, to analyse the institutional mechanisms set up by the Soviet authorities (namely the Moldovan Writers Union (MWU) and AgitProp) to integrate these writers into the Soviet cultural system. The three groups of Bessarabian writers remaining in the annexed territory (the ‘regionalists’ from Viaţa Basarabiei journal, the writers of Jewish origin and the formerly ‘underground’ (pro-Communist) activists) intersected and overlapped, since the writers’ interests were often multiple. At the same time, the strategies implemented by the Soviet authorities to enrol Bessarabian writers into the Soviet institutional structures followed a binary and apparently contradictory rationale, of inclusion (of candidates deemed suitable for the aspiring status) and exclusion (of those who did not correspond to the criteria of political probity).

Theability to manage one’s own process of learning (metalearning) is necessary and required of nearly any professional. To develop this skill, you need to have the creative attitude, i.e., to be critical and reflective towards yourself as a learner. This applies even more to teachers, who do not only learn how to learn but should also be able to ensure their students proper conditions for learning this skill. On the other hand, as a person who prepares children and adolescents for creative life in the new millennium, a teacher should display a special level of creativity. The aim of the study presented in this article was to identify the relationship between the creative attitude and metalearning competence of first-year pedagogy students. The results of the study show a statistically significant relationship between the creative attitude and metalearning competence level of pedagogy students.

In approaching the subject of the patination of flint implements, I am profoundly impressed with the very great difficulties of the subject; so much so indeed that I feel that some initial apology is called for. It requires some courage, nay, one may say temerity, to attack a series of problems that bristle with difficulties of a most formidable kind, about which nothing is known; and for a solution of which chemical and physical knowledge of a very high order, backed up by the aid of full laboratory equipment, is required. All this is wanting in my own case; but on the other hand I have a large first-hand acquaintance with the flints in question; for many years I have devoted much attention to the conditions in which patination is found, jand to its manifold varieties—it has been my constant endeavour to co-ordinate given patinations with other factors more or less ascertainable in connection with the flints. In this way I think I have arrived at conclusions which, though by ao means complete in themselves, may at any rate serve as points of departure or of support in the further investigations which are urgently required. I propose to divide my paper into three sections—(1) General considerations bearing on the study of patina, (2) The conditions under which patina is produced, (3) The changes in flint associated with the production of patina.

In this paper, we present a graphical method, developed in CATIA environment, based on the method of substituting circles family and dedicated to profile pinion cutters for generating interior surfaces. Hereby, the family of substituting circles associated to the worked piece (the profile to be generated) is determined at the same time to the curve transposed, in the rolling motion, to the tool centrod. After finding the position of the contact points between the generated profile and the family circles, we can determine, in the transposed family, the locus of the points from the reciprocal enwrapping profile the pinion cutter profile. The paper also includes a method application for generating a hole with square transversal section, and a comparison between the profiling results when using the graphical method, versus an analytical method. The results prove the coincidence between the two profiles determined as above, on one hand, and both rapidity and precision of the graphical method, on the other hand.

The purpose of this article is twofold: primarily to draw attention to the evidence for a hitherto unrecognised plot against the throne of Alexander the Great; and incidentally to re-examine the evidence for the regency of Philip II on behalf of his nephew Amyntas son of Perdikkas—a subject which has important repercussions on the main theme.Until the end of the nineteenth century students of the reign of Philip II of Macedon, on confronting the question of Philip's regency, had simply to make a choice between the circumstantial (but at least partly incorrect) notice of Justin—who says he was regent—and the contrary indication or implication of Diodorus and all other sources, contemporary or later, including of course Demosthenes.On the death of Perdikkas III in battle against the Illyrians Philip ‘became king of Macedonia, in the archonship of Kallimedes, the first year of Olympiad 105’ (359 B.C.). So says a scholiast on Aischines iii 51. Philip ‘was king over (ἐβασίλєυσєν) the Macedonians for 24 years’, says Diodorus—that is, from 359 to 336. On the other hand, Justin claims that on Perdikkas' death Philip became regent; he remained for a long time—diu—non regem sed tutorem pupilli. His pupillus, his ‘ward’, was Amyntas, son of the late king and nephew of Philip. As Macedonia was threatened, continues this author, with serious wars and required the leadership of more than a mere boy, Philip compulsus a populo regnum suscepit.

By means of the Directive 2014/95/EU, the EU established new requirements regarding the disclosure of non-financial information (NFI). The Spanish Act 11/2018 expands these requirements, imposing mandatory external assurance on NFI. This is a pioneering study in Spain, since it was conducted during the first year in which external assurance is mandatory. The aim of this paper is to analyse whether Spanish listed companies fulfil this requirement and to compare assurance practices before the entry into force of the Act and afterwards. Our findings indicate that some companies still fail to adopt external assurance in spite of being mandatory. We found no significant association between the choice of type of assuror and the entry into force of the Act, but this choice depends on some corporate characteristics. On the other hand, we found that the Act implementation and the type of assuror are associated with some assurance features.

The purpose of the study is to improve students’ reading comprehension of narrative text using Picture and Picture. This study is delimited on using picture and picture in teaching reading comprehension in Narrative Text to the first year student of SMK Santa Familia Tomohon. In this research, the researchers use quantitative research. Where quantitative research is used to obtain and to collect the data in the form of numbers, through Pre-experimental design with one group pre-test and post-test. Based on the explanation of previous chapters, it can be concluded that; picture and picture technique is effective to improve students’ reading comprehension, teaching reading comprehension by using picture and picture can help student improving their comprehension in reading and increase their cooperation to develop the other language skills. Then, the result of this research shows that the students’ score in Post-test is higher than their score in Pre-test. It means that Picture and Picture technique in teaching reading comprehension is effective. Therefore, it is suggested to apply Picture and picture technique in class related to the situation and material that is going to be taught in school to improve more about students’ skill not only in group but also personally. The teacher is suggested to pay more attention to increase students’ comprehension in reading. Keywords:        Reading, Picture and Picture Technique, Pre-experimental

ABSTRACT Opponents of mandatory rotation argue that a change of partner is bad for audit quality, as it results in a loss of client-specific knowledge. On the other hand, proponents argue that a change of partner is beneficial, as it results in a positive peer review effect and a fresh perspective on the audit. We test the impact of mandatory partner rotation on audit quality using a unique dataset of audit adjustments in China. Our results suggest that mandatory rotation of engagement partners results in higher quality audits in the years immediately surrounding rotation. Specifically, we find a significantly higher frequency of audit adjustments during the departing partner's final year of tenure prior to mandatory rotation and during the incoming partner's first year of tenure following mandatory rotation.
