Internal Migration and Regional Population Dynamics in Europe: Finland Case Study
Both natural increase and internal migration have played roles in the shaping of population distribution of Finland since 1900. Far reaching recent changes in the economy have brought about massive shift of jobs from agriculture to manufacturing and services. As a result people have relocated from rural to urban areas. Both natural change and net migration have distinct geographical patterns, resulting in serious depopulation in remote areas in the east and north of the country. Internal migration benefits the south, the west, coastal areas, urban agglomerations and suburban areas. International migration is a marginal phenomenon in Finland and has little impact on population dynamics. Net migration losses in the past were offset by high natural increase and in recent decades Finnish emigrants have returned.
Urban concentration is a dominant feature of the Finnish migration system. At the subregional level, suburbanisation is visible, but is not as strong as in the overcrowded metropolises of Western Europe. The relationships between migration and size of municipality, migration and population density and migration and urban/rural class of municipalities show that the process of concentration is the strongest force at work in shifting people to urban agglomerations and their suburban rings.
Regional patterns of migration show strong transfers of population from north and east to south and to lesser extent to west of the country. The Baltic Sea coast has a strong attraction to migrants. Migration is sex-selective, with a much higher propensity of females to leave remote and rural areas and migrate to urban centres and the southern part of the country. The result is a significant gender imbalance: a deficiency of females in rural areas and in the north and east of the country and a surplus in urban and semi-urban areas. However, the economic indicator unemployment has a rather weak and imprecise effect on migrants
The Costs of Biosecurity at the Farm Level: the Case of Finnish Broiler
In the European Union, the animal health and food safety strategy includes managing biosecurity along the entire production chain. Farm-level biosecurity provides the foundation for this. However, the farm-level costs of preventive biosecurity have rarely been assessed. Yet many risk management practices are in place constantly regardless of whether there is a disease outbreak or not. We contribute towards filling this information gap by studying the costs incurred in preventive biosecurity by the Finnish poultry farms. In a preliminary analysis, we find that the cost of biosecurity is some 3.55 cents per bird for broiler producers and 75.7 cents per bird for hatching egg producers. The results indicate that work-time devoted to biosecurity represents some 8% of total work time on broiler farms and about 5% on breeder farms.Biosecurity, on-farm costs, poultry, Livestock Production/Industries,

A radio continuum survey of edge-on spiral galaxies at 90 cm
Accurate spectral indices of the radio emission from both the thin disk and thick disk or halo components are critical to understanding the propagation mechanisms of electrons within spiral galaxies. The spectral indices give information of relative importance of diffusion and synchrotron energy loss in the propagation of electrons in the disk. Our goal of this survey is to locate a larger sample of spiral galaxies that exhibit halo phenomena so that a statistical analysis will be possible
Meat Consumption Patterns and Intentions for Change Among Finnish Consumers
During the past few decades, meat has increasingly become a subject of controversies relating to health and safety, environment, and animal welfare. Even though these changes in perceptions of meat are not yet visible in aggregate consumption figures, they can be observed in individual consumption patterns and as intentions to change the consumption. In this study, we examine changes in meat consumption among the Finnish consumers taking into account both stated changes in the past and intended changes in the future. Based on these changes, we identify consumer segments and investigate in which ways these segments differ from each other socio-demographically and with respect to current meat consumption and the stated reasons for the change. The latent class analysis based on representative Internet survey data revealed nine consumer clusters that formed three cluster blocks. The results showed that a large number of people, over 40%, had stabile consumption patterns. A cluster block of 14% of consumers had already shifted their consumer patterns to contain more vegetables and less meat. One third of the consumers were identified to be in the middle of the change with a general tendency to decrease the use of meat and increase the use of vegetables. Although, environmental effects of meat and animal welfare issues were important reasons for change in some clusters, healthiness was the most salient stated reason for change in consumption habits.Food Consumption/Nutrition/Food Safety, Livestock Production/Industries,
Program evaluation primer: A review of three evaluations
Program evaluationâa âtool used to assess the implementation and outcomes of a program, to increase a programâs efficiency and impact over time, and to demonstrate accountabilityâ (MacDonald et. al, 2001, p. 1)âis an essential process to program assessment and improvement. This paper overviews three published program evaluations and considers important aspects of program evaluation more broadly
An Analysis of the Impact of Information Security Policies on Computer Security Breach Incidents in Law Firms
Law firms maintain and store voluminous amounts of highly confidential and proprietary data, such as attorney-client privileged information, intellectual properties, financials, trade secrets, personal, and other sensitive information. There is an ethical obligation to protect law firm client data from unauthorized access. Security breaches jeopardize the reputation of the law firm and could have a substantial financial impact if these confidential data are compromised. Information security policies describe the security goals of a law firm and the acceptable actions and uses of law firm information resources.
In this dissertation investigation, the author examined the problem of whether information security policies assist with preventing unauthorized parties from accessing law firm confidential and sensitive information. In 2005, Doherty and Fulford performed an exploratory analysis of security policies and security breach incidents that highlighted the need for research with different target populations. This investigation advanced Doherty and Fulford\u27s research by targeting information security policies and security breach incidents in law firms. The purpose of this dissertation investigation was to determine whether there is a correlation between the timing of security policy development (proactive versus reactive policy development) and the frequency and severity of security breach incidents in law firms of varying sizes.
Outcomes of this investigation correlated with Doherty and Fulford\u27s general findings of no evidence of statistically significant relationships between the existence of a written information security policy and the frequency and severity of security breach incidents within law firms. There was also a weak relationship between infrequency of information security policy updates and increase of theft resources. Results demonstrated that, generally, written information security policies in law firms were not created in response to a security breach incident. These findings suggest that information security policies generally are proactively developed by law firms.
Important contributions to the body of knowledge from this analysis included the effectiveness of information security policies in reducing the number of computer security breach incidents of law firms, an under represented population, in the information assurance field. Also, the analysis showed the necessity for law firms to become more immersed in state security breach notification law requirements
A Glance to the Fragmenta Membranea Manuscript Collection Through Ftir and Radiocarbon Analyses
The Fragmenta membranea manuscript fragment collection at the National Library of Finland has proved challenging to date using only traditional paleography. Therefore, radiocarbon dates can contribute to the understanding of these fragments by offering a parallel natural scientific timeline for the parchment the manuscripts are written on. In this study, we apply our previously developed method for radiocarbon dating medieval manuscripts made of parchment. In total 35 datings were made from 14 separate assemblages of manuscripts, being the first systematic wide-scale application of radiocarbon dating to a collection of medieval manuscripts in order to improve their chronological proxy. Additionally, due to the fragmentary and sometimes poor condition of the manuscript fragments of Fragmenta membranea analyzed in this study, we used Fourier-transform infrared spectroscopy (FTIR) to evaluate the quality of the collagen and the presence of contaminants in the fragments affecting the radiocarbon dates. We report out radiocarbon dating results and FTIR screenings for each sample and for each manuscript assemblage, and discuss the applicability of our method in further studies of applying radiocarbon dating on objects of cultural historical interest and value. The results indicate an essential role of high-quality samples and multiple measurements to interpret the radiocarbon dating results.Peer reviewe
Camera distortion self-calibration using the plumb-line constraint and minimal Hough entropy
In this paper we present a simple and robust method for self-correction of
camera distortion using single images of scenes which contain straight lines.
Since the most common distortion can be modelled as radial distortion, we
illustrate the method using the Harris radial distortion model, but the method
is applicable to any distortion model. The method is based on transforming the
edgels of the distorted image to a 1-D angular Hough space, and optimizing the
distortion correction parameters which minimize the entropy of the
corresponding normalized histogram. Properly corrected imagery will have fewer
curved lines, and therefore less spread in Hough space. Since the method does
not rely on any image structure beyond the existence of edgels sharing some
common orientations and does not use edge fitting, it is applicable to a wide
variety of image types. For instance, it can be applied equally well to images
of texture with weak but dominant orientations, or images with strong vanishing
points. Finally, the method is performed on both synthetic and real data
revealing that it is particularly robust to noise.Comment: 9 pages, 5 figures Corrected errors in equation 1
The detection of extragalactic N: Consequences for nitrogen nucleosynthesis and chemical evolution
Detections of extragalactic N are reported from observations of the
rare hydrogen cyanide isotope HCN toward the Large Magellanic Cloud
(LMC) and the core of the (post-) starburst galaxy NGC 4945. Accounting for
optical depth effects, the LMC data from the massive star-forming region N113
infer a N ratio of 111 17, about twice the C
value. For the LMC star-forming region N159HW and for the central region of NGC
4945, N ratios are also 100. The N ratios
are smaller than all interstellar nitrogen isotope ratios measured in the disk
and center of the Milky Way, strongly supporting the idea that N is
predominantly of `primary' nature, with massive stars being its dominant
source. Although this appears to be in contradiction with standard stellar
evolution and nucleosynthesis calculations, it supports recent findings of
abundant N production due to rotationally induced mixing of protons into
the helium-burning shells of massive stars.Comment: 15 pages including one postscript figure, accepted for publication by
