The spectral representation of a moving average process obtained as a convolution of a kernel with a general noise measure is studied. A proof of the spectral theorem that yields explicit expression for the spectral measure in terms of the noise measure is presented. The main interest is in noise measures generated by second order Lévy motions. For practical considerations, such measures are easil

The rapid expansion of the university sector has channelled many students into study programs that lead to employment in new kinds of jobs, occupations and professional groups. There are three main reasons why more and more occupations get their training within the university system  (a)    The qualification and competence level of the labour force has been raised, due to changes in the economy an

In this paper we study the distribution of the product of an inverse Wishart random matrix and a Gaussian random vector. We derive its asymptotic distribution as well as its approximate density function formula which is based on the Gaussian integral and the third order Taylor expansion. Furthermore, we compare obtained asymptotic and approximate density functions with the exact density which is o

Emerging multiculturalism in China's metropolitan areas implies people's frequent engagement in intercultural contacts and, therefore, creates a need for a mutual acculturation between the migrants and the host society. This research aimed to contribute to the study of immigrant adjustment in China by exploring the patterns of dietary acculturation among Russian immigrants residing in Beijing. The

Since 2009, Japanese civil society groups have arranged exhibitions in China dealing with the so-called comfort women issue in cooperation with local Chinese organizers, including state-run war museums that function as patriotic education bases. Organizing these exhibitions has required much time and energy. A fundamental aim of these groups is to make the Japanese government compensate the victim

The third moment cumulant for the aggregated multivariate claims is considered. A formula is presented for the general case when the aggregating variable is independent of the multivariate claims. It is discussed how this result can be used to obtain a formula for the third cumulant for a classical model of multivariate claims. Two important special cases are considered. In the rst one, multivaria

The collective identity is subject to permanent negotiation. Due to the lack of incentive to offer public statements, the collective identity of Japanese bureaucrats (or kanryo, 官僚) has been constructed separately inside and outside of the ministries. This paper explores how the collective identity of kanryo has been constructed in two Japanese national newspapers as outsider discourses using stru

Broad public contention against nuclear energy can be observed as a new phenomenon in Japanese society after the 2011 Fukushima Daiichi nuclear power plant accident. This study aimed to identify a sufficient explanation about why the emergence of such a protest movement only occurred after the direct experience of a critical event and did not happen before. Discrediting a sole and simple grievance

When evaluating whether the effect of one treatment is larger than that of another the first step in the comparison is to decide what should be understood by the statement that one patient has achieved a greater effect than has another patient. When the outcome variable is quantitative, measured on a ratio scale, absolute or relative effects are the most commonly used effect measures; however, suc

The position of English vis-a-vis Swedish in Sweden is gaining attention because of a growing concern that the encroachment of English in certain Swedish domains will result in Swedish simultaneously losing ground. A current language policy proposal, entitled Mal i mun, commissioned by the Swedish government addresses this concern, in part, by outlining recommendations for the respective roles of
