Stop Loss reinsurance has attracted the interest of ASTIN members for years. May I recall the paper of Borch [1] in which he demonstrates some optimality qualities of the stop loss reinsurance from the ceding company's point of view, the contribution of Kahn [2] and the paper of Pesonen [3]. I also mention the paper of Esscher [4] and Verbeek's contribution [5]. Going back to the pre-ASTIN days we find a paper of Dubois [6].The rating problems have been dealt with by several authors. Let me recall the rating formula worked out by a group of Dutch Actuaries some 20 years ago. This was based on the assumption that the mean and the standard deviation were known. Based on Chebycheff's inequality an approximation formula was worked out which, of course, was heavily on the safe side.Even younger members of ASTIN are probably familiar with the studies made in the early sixties by a group of Swedish Actuaries, the results of which were presented by Bohman at the Actuarial Congress in London in 1964. Partly based on this, Bühlmann worked out some tables which he used for rating purposes.My present contribution to the subject may not justify the above reviews, particularly as I will deal with a very special retention situation which a practical underwriter will rightly not accept, namely a stop-loss point as low as equal to the mean value of the distribution.My excuse for this is that the formula deduced is very handy and that it is of value to the underwriter to know the stop loss risk rate also at this low level.

There are a wide range of options for individuals to choose from in order to engage in aerobic exercise; from outdoor running to computer controlled and self-propelled treadmills. Recently, self-propelled treadmills have increased in popularity and provide an alternative to a motorized treadmill. Twenty subjects (10 men, 10 women) ranging in age from 19-23 with a mean of 20.4 ± 0.8 SD were participants in this study. The subjects visited the laboratory on three occasions. The purpose of the first visit was to familiarize the subject with the self-propelled treadmill (Woodway Curve 3.0). The second visit, subjects were instructed to run on the self-propelled treadmill for 3km at a self-determined pace. Speed data were collected directly from the self-propelled treadmill. The third visit used speed data collected during the self-propelled treadmill run to create an identically paced 3km run for the subjects to perform on a motorized treadmill (COSMED T150). During both the second and third visit, oxygen consumption (VO2) and respiratory exchange ratio (R) data were collected with COSMED’s Quark cardiopulmonary exercise testing (CPET) metabolic mixing chamber system. The VO2 mean value for the self-propelled treadmill (44.90 ± 1.65 SE ml/kg/min) was significantly greater than the motorized treadmill (34.38 ± 1.39 SE ml/kg/min). The mean R value for the self-propelled treadmill (0.91 ± 0.01 SE) was significantly greater than the motorized treadmill (0.86 ± 0.01 SE). Our study demonstrated that a 3km run on a self-propelled treadmill does elicit a greater physiological response than a 3km run at on a standard motorized treadmill. Self-propelled treadmills provide a mode of exercise that offers increased training loads and should be considered as an alternative to motorized treadmills.

It is increasingly realized that hypnosis may be seen from an interpersonal point of view, meaning that it forms part of the relationship between the hypnotist and the subject. From this premise it follows that what goes on in the relationship prior to hypnosis probably has an influence on the hypnosis. Certain of these prior occurences can then be seen as waking suggestionns (however implicitly given) that the subject should behave in a certain way with regard to the subsequent hypnosis. A study was conducted to test the hypothesis that waking suggestions regarding post-hypnotic amnesia are effective. Eighteen female subjects were randomly divided into two groups. The groups listened to a tape-recorded talk on hypnosis in which for the one group amnesia for the subsequent hypnotic experience and for the other group no such amnesia was suggested. Thereafter the Stanford Hypnotic Susceptibility Scale was administered to all subjects. Only the interrogation part of the amnesia item of the scale was administered. The subjects to whom post-hypnotic amnesia was suggested tended to score lower on the amnesia item than the other subjects, as was expected, but the difference between the mean amnesia scores of the two groups was not significant.

We compute the mean two-point spectral form factor and the spectral number variance for permutation matrices of large order. The two-point correlation function is expressed in terms of generalized divisor functions, which are frequently discussed in number theory. Using classical results from number theory and casting them in a convenient form, we derive expressions which include the leading and next to leading terms in the asymptotic expansion, thus providing a new point of view on the subject, and improving some known results.

Purpose This paper aims to provide guidance on cloud computing assurance from an IT governance point of view. The board and executive management are tasked with ensuring proper governance of organizations, which should in the end contribute to a sense of assurance. Assurance is understood to be a part of corporate governance which provides stakeholders with confidence in a subject matter by evaluating evidence about that subject matter. Evidence will include proof that proper controls and structures are in place, that risks are managed and that compliance with internal and external requirements is demonstrated with regard to the subject matter. Decisions regarding the use of cloud computing in organizations bring these responsibilities to the fore. Design/methodology/approach The design of this paper is based on an extensive review of literature, predominantly best practices and standards, from the fields covering IT governance, cloud computing and assurance. Findings The results from this paper can be used to formulate cloud computing assurance evidence statements, as part of IT governance mandates. Originality/value This paper aims to add value by highlighting the responsibility of managers to ensure assurance when exploiting opportunities presented through IT advances, such as cloud computing; serving to inform management about the advances that have and are being made in the field of cloud computing guidelines; and motivating that these guidelines be used for assurance on behalf of organizations adopting and using cloud computing.

Normoblast is an immature form of erythrocyte in erythropoietin system. Normally, normoblast can be found in peripheral blood healthy neonates. The existence of normoblast in peripheral blood might be the sign of pathologic conditions such as hemolytic anemia,acute blood loss, and ischemia and bone marrows abnormalities like malignancy or leukemia. In acute leukemia (Acute MyeloblasticLeukemia and Acute Lymphoblastic Leukemia), normoblast existence in peripheral blood may due to erythropoietin system suppression.The aim of this study is to compare normoblast count between AML and ALL, and also to find out the correlation between leukocyte andnormoblast count in AML and ALL. The subject of this study were patient diagnosed as AML (30) and ALL (30) in Hematology Divisionof Clinical Pathology Department at Dr.Hasan Sadikin Hospital Bandung in July 2006–August 2008. In this study we examined 30peripheral blood smears from AML and 30 peripheral blood smears from ALL. Leukocyte count result was derived from CBC performedwith Sysmex KX-21. The mean value of normoblast count from AML blood smear patients is 1930.60 (3.60/100 WBC) while ALL bloodsmear patients is 309.60 (0.43/100 WBC). Statistically this difference is significant (p < 0.001). There are strong correlation betweenleukocyte count and normoblast count within both group (r = 0.851, r = 0.948; p < 0.001).

In this paper, we proposed a modification of the measurement of the personality consistency level of the Pauli &amp; Kraepelin Test in the field of psychology, using the formula made in April 2016, by Sigit Haryadi, and named "the Harmony in Gradation" or “the Haryadi Index”. The purpose of this proposal is because the existing formula uses only the mean value of the deviation, which leads to the possibility that the result of consistency measurement on people whose facts are different levels of consistency will be considered to have the same consistency level, on the other hand, the proposed method will be more accurate and precise in terms of providing an assessment of the level of personality consistency of a person.

Introduction. The relevance of the study of the concept of subjectivity in the work of I.A. Ilyin is connected with the fact that the center of the philosophical reflection of the Russian thinker is anthropological problems of a worldview nature, which is consonant with the developments of both domestic researchers and foreign thinkers in connection with permanent attempts to overcome the current crisis of understanding the human phenomenon in modern humanitarian knowledge.Materials and Methods. The research material is the work of I.A. Ilyin, related to subjectivist themes. The principle of historicism, concreteness, the method of reconstruction, the comparative method and the phenomenological approach are the methodological basis that makes it possible to optimally explicate the developments of I.A. Ilyin in the field of subjectivity.Results. It was established that the problem of subjectivity is a backbone for the philosophical system of I.A. Ilyin. Models of German classical philosophy from the point of view of I.A. Ilyin reveal their inconsistency, while the phenomenological approach requires supplementation from the standpoint of ontological realism. From the point of view of I.A. Ilyin, personality gains its concreteness through connection with the initiating personality of the Absolute.Discussions and Conclusions. The study allowed to carry out an explication, a constitution and an analysis of the concept of human subjectivity in the work of I.A. Ilyin. The originality of the understanding of subjectivity in the personalistic philosophy of I.A. Ilyin is made in the context of the thinker's creative reflection on the views of Kant, Fichte, Hegel and Husserl. I.A. Ilyin believes that a consistent model of the subject can be built only taking into account all anthropological constants, including both the rational and the spiritual components in their orientation towards the absolute Subject.

The problem with which this paper is concerned arose in the discussion of a series of chronometric observations, but it is of more general application, and is capable of wide extension. Pairs of readings (xi yi) were taken at times ti, i = 1, 2, …, n. These readings were known to be affected by respective errors (ξi ηi) from sources different but possessing some common part. It was important to have an estimate of the consequent correlation and to assess its precision. The assumptions made in the particular experiment were that x and y were both linear in t, representable by x = a0 + a1t, y = b0 + b1t, and that the distributions of error in x and y were normal. The parameters a0 and a1, b0 and b1 were therefore obtained from two separate sets of normal equations, and the unknown correlation was then estimated from the sum of products of corresponding residuals ui, vi, one from each set. In the corresponding situation in n samples (xi,yi) from a bivariate normal distribution the mean value of is (n − 1) ρσ1σ2, where σ12, σ22 are the variances of x and y and ρσ1σ2 is their product moment. One might therefore anticipate, by analogy, that in the present case the mean value of Σuivi would be (n − 2)ρσ1σ2. So indeed it proves to be, and the sampling variance of Σuivi conforms likewise with standard results; but it is desirable, by an extension of the problem, both to see why this is so and to take notice of cases where the analogy fails to hold.
