Theoretical study on travelling web dynamics and instability under non-homogeneous tension

2013

Problems of dynamics and stability of a moving web, travelling between two rollers at a constant velocity, are studied using analytical approaches. Transverse vibrations of the web are described by a partial differential equation that includes the centrifugal force, in-plane tension, elastic reaction and nonstationary inertial terms. The model of a thin elastic plate subjected to bending and non-homogeneous tension is used to describe the bending moment and the distribution of membrane forces. The stability of the plate is investigated with the help of studies of small out-of-plane vibrations. The influence of linearly distributed in-plane tension on the characteristics of the web vibration…

Poverty and Tax Exemptions in Mid-Nineteenth Century Finland

2017

The topic of this article is the nature and social character of Finnish rural poverty during the early stages of industrialization. Specifically, I analyze households exempted from two separate taxes in order to locate and study the rural poor. Contrary to several previous considerations deeming taxation sources unreliable in poverty studies, it is shown that under controlled settings tax exemption information does display promising features. These include a high exemption percentage of households without adult male members, small average household size of the tax exempted and a clear concentration of the exemptions on the lower rural social classes. My findings also highlight the fact that…

Guanxi and social capital: Networking among women managers in China and Finland

2014

Considering that women are still under-represented in management, researchers have claimed that networking is an important career management tool for women. This study aims to empirically explore how women managers benefit from social networks in the information technology (IT) field in China and Finland. Guanxi, an Eastern term for social networking, has seldom been studied in terms of gender and career, especially within cross-cultural research. Social capital is a Western term for social networks. Using questionnaires, in-depth interviews and interpretive analysis, we compare the composition and structure of social networks used by women managers within the information technology sector …

China's economic, environmental and social development in crossfire : province-specific analysis of China's ecological modernization and sustainabili…

2014

Häyhä, Laura. China’s Economic, Environmental and Social Development in Crossfire – Province-specific Analysis of China’s Ecological Modernization and Sustainability. Master thesis. Autumn 2014. Supervisor: Pertti Jokivuori. Sociology. University of Jyväskylä. Pages 89 + 1 appendix. This study concentrated to examine ecological modernization process and sustainability of Chinese provinces. The examination focused on the differences between the westernmost and the easternmost China. Data of Chinese Statistical Yearbook was used during the years 2001–2010. Analyses were implemented with SPSS 20. and Excel 2010. Among general statistical analysis, Principal Component Analysis and a relatively …

Hidden and self-excited attractors in radiophysical and biophysical models

2017

One of the central tasks of investigation of dynamical systems is the problem of analysis of the steady (limiting) behavior of the system after the completion of transient processes, i.e., the problem of localization and analysis of attractors (bounded sets of states of the system to which the system tends after transient processes from close initial states). Transition of the system with initial conditions from the vicinity of stationary state to an attractor corresponds to the case of a self-excited attractor. However, there exist attractors of another type: hidden attractors are attractors with the basin of attraction which does not have intersection with a small neighborhoods of any equ…

Rethinking Civil Society in Development: Scales and Situated Hegemonies

2016

Ethnic residential segregation is often explained with the claim that ‘immigrants don’t want to integrate—they prefer to stick together with co-ethnics’. By contrast, mixed neighbourhoods are seen as crucial for achieving social cohesion. In line with spatial assimilation theory there is a normative assumption that people interact with those living nearby. From interviews on neighbourhood qualities and locations valued by Oslo residents of Turkish, Somali and Polish backgrounds, we raise questions about the validity of two assumptions: that most immigrants want to live in the same neighbourhoods as co-ethnics; and that they want to live close to co-ethnics because they do not want to integr…

Extended music education enhances the quality of school life

2013

The claim of whether music education can create social benefits in the school environment was tested in 10 Finnish schools with an extended music curricular class and control classes. The quality of school life (QSL) was assessed by a representative sample (N=735) of pupils at years 3 and 6 (9- and 12-years-olds). The results showed that extended music education enhances the QSL, particularly in areas related to general satisfaction about the school and a sense of achievement and opportunity for students. Differences related to the schools and gender did not account for the results. A follow-up study examined whether the increase in critical QSL variables was related to music. This analysis…

Systematisation of Systems Solving Physics Boundary Value Problems

2020

A general conservation law that defines a class of physical field theories is constructed. First, the notion of a general field is introduced as a formal sum of differential forms on a Minkowski manifold. By the action principle the conservation law is defined for such a general field. By construction, particular field notions of physics, e.g., magnetic flux, electric field strength, stress, strain etc. become instances of the general field. Hence, the differential equations that constitute physical field theories become also instances of the general conservation law. The general field and the general conservation law together correspond to a large class of relativistic hyperbolic physical …

A two-phase problem with Robin conditions on the free boundary

2020

We study for the first time a two-phase free boundary problem in which the solution satisfies a Robin boundary condition. We consider the case in which the solution is continuous across the free boundary and we prove an existence and a regularity result for minimizers of the associated variational problem. Finally, in the appendix, we give an example of a class of Steiner symmetric minimizers. peerReviewed
