Henkilöstönäkökulma kuntien yhdistymiseen, Case: Kouvolan kaupunki

Tutkimuksen tavoitteena oli selvittää miten henkilöstö kokee kuntien yhdistymistä seuraavan organisaatiomuutoksen, millaista muutosjohtamista organisaatio tarvitsee sekä mitkä tekijät vaikuttavat muutokseen suhtautumiseen. Tutkimus on laadullinen tapaustutkimus, jonka empiirisen aineiston muodostavat Kouvolan kaupungin yhdentoista hallinnon ja talouden toimistotyöntekijän haastattelut sekä niihin liittyvä sähköpostikysely. Tutkimustulokset osoittavat, että muutos on aina yksilöllinen kokemus, ja muutostilanteessa korostuu erityisesti läsnä oleva ja keskusteleva esimiestyö. Henkilöstön oma osallistuminen ja vaikutusmahdollisuudet auttavat muutokseen sopeutumisessa. Myös avoimella ja vuorovaikutteisella viestinnällä on suuri merkitys muutoksen toteuttamisen onnistumisessa.

Improving Label Space Usage for Ethernet Label Switched Paths

Ethernet is becoming the dominant aggregation technology for carrier transport networks; however, as it is a LAN technology, native bridged ethernet does not fulfill all the carrier requirements. One of the schemes proposed by the research community to make ethernet fulfill carrier requirements is ethernet VLAN-label switching (ELS). ELS allows the creation of label switched data paths using a 12-bit label encoded in the VLAN TAG control information field. Previous label switching technologies such as MPLS use more bits for encoding the label. Hence, they do not suffer from label sparsity issues as ELS might. This paper studies the sparsity issues resulting from the reduced ELS VLAN-label space and proposes the use of the label merging technique to improve label space usage. Experimental results show that label merging considerably improves label space usage

Dynamic patterns of flow in the workplace: characterizing within-individual variability using a complexity science approach

As a result of the growing interest in studying employee well-being as a complex process that portrays high levels of within-individual variability and evolves over time, this present study considers the experience of flow in the workplace from a nonlinear dynamical systems approach. Our goal is to offer new ways to move the study of employee well-being beyond linear approaches. With nonlinear dynamical systems theory as the backdrop, we conducted a longitudinal study using the experience sampling method and qualitative semi-structured interviews for data collection; 6981 registers of data were collected from a sample of 60 employees. The obtained time series were analyzed using various techniques derived from the nonlinear dynamical systems theory (i.e., recurrence analysis and surrogate data) and multiple correspondence analyses. The results revealed the following: 1) flow in the workplace presents a high degree of within-individual variability; this variability is characterized as chaotic for most of the cases (75%); 2) high levels of flow are associated with chaos; and 3) different dimensions of the flow experience (e.g., merging of action and awareness) as well as individual (e.g., age) and job characteristics (e.g., job tenure) are associated with the emergence of different dynamic patterns (chaotic, linear and random).

Image Segmentation Using Information Bottleneck Method

In image processing, segmentation algorithms constitute one of the main focuses of research. In this paper, new image segmentation algorithms based on a hard version of the information bottleneck method are presented. The objective of this method is to extract a compact representation of a variable, considered the input, with minimal loss of mutual information with respect to another variable, considered the output. First, we introduce a split-and-merge algorithm based on the definition of an information channel between a set of regions (input) of the image and the intensity histogram bins (output). From this channel, the maximization of the mutual information gain is used to optimize the image partitioning. Then, the merging process of the regions obtained in the previous phase is carried out by minimizing the loss of mutual information. From the inversion of the above channel, we also present a new histogram clustering algorithm based on the minimization of the mutual information loss, where now the input variable represents the histogram bins and the output is given by the set of regions obtained from the above split-and-merge algorithm. Finally, we introduce two new clustering algorithms which show how the information bottleneck method can be applied to the registration channel obtained when two multimodal images are correctly aligned. Different experiments on 2-D and 3-D images show the behavior of the proposed algorithms

An octree isosurface codification based on discrete planes

Describes a method to code a decimated model of an isosurface on an octree representation while maintaining volume data if it is needed. The proposed technique is based on grouping the marching cubes (MC) patterns into five configurations according the topology and the number of planes of the surface that are contained in a cell. Moreover, the discrete number of planes on which the surface lays is fixed. Starting from a complete volume octree, with the isosurface codified at terminal nodes according to the new configuration, a bottom-up strategy is taken for merging cells. Such a strategy allows one to implicitly represent co-planar faces in the upper octree levels without introducing any error. At the end of this merging process, when it is required, a reconstruction strategy is applied to generate the surface contained in the octree intersected leaves. Some examples with medical data demonstrate that a reduction of up to 50% in the number of polygons can be achieved

Determinação turbidimétrica de metilbrometo de homatropina em formulações farmacêuticas empregando um sistema de análise por injeção em fluxo

A flow injection turbidimetric procedure exploiting merging zones is proposed for determining homatropine methylbromide (HMB) in pharmaceutical preparations. The determination is based on the precipitation reaction of homatropine methylbromide with AgNO3 solution to form a precipitate, which was measured at 410 nm. The analytical curve was linear in the HMB concentration range from 8.0x10-4 to 1.7x10-3 mol L-1, with a detection limit of 9.5x10-5 mol L-1. The recoveries ranged from 94.9 to 104 %, the sampling frequency was 75 h-1 and relative standard deviations were smaller than 2.0 % for solutions containing 1.2x10-3 and 1.5x10-3 mol L-1 HMB (n=10). The results obtained for commercial formulations using the FIA procedure were in good agreement with those obtained by using a comparative method (r= 0.9983).

Direct determination of calcium in milk by atomic absorption spectrometry using flow-injection analysis

A flow-injection system with sample and reagent addition by the synchronous merging zones approach for calcium determination in milk by flame AAS is proposed. Main parameters were optimized using a factorial design with central point. The optimum conditions were 2.5% (m/v) for La concentration, 8 mL min-1 for the carrier flow-rate, 20 cm for coiled reactor and 250 ìL for sample volume. Different sample preparation procedures were evaluated such as dilution in water or acid and microwave-assisted decomposition using concentrated or diluted acids. The optimized flow system was applied to determine Ca in eleven commercial milk samples and two standard reference materials diluted in water. Similar calcium levels were encountered comparing the results obtained by the proposed method (dilution in water) with those obtained using microwave-oven digestion. Results obtained in two standard reference materials were in agreement at 95% confidence level with those certified. Recoveries of spiked samples were in the 93% - 116% range. Relative standard deviation (n = 12) was < 5.4% and the sample throughput was 150 measurements per hour, corresponding to a consumption of 250 µL of sample and 6.25 mg La per determination.

Hälsans grund kan bara hjärtat förstå : ett sökande efter kunskap om hälsa i ljuset av Blaise Pascals tänkande

The aim of this thesis is to gain new understanding of health based on the work Penseés (Thoughts) by Blaise Pascal. The research interest originates from the motive of the heart for the greatness of man in conjunction with his baseness. The study is hermeneutic and the purpose is to describe health formulated as new abductive theses based on the assumption that caring science and caring theology can be conjoined in the same ontology. The work Penseés is, in Gadamer’s sense, alive since the text is constantly being made use of and is in this occurence interpreted through the requirements made by caring science. Pascal’s arguments continue through the historically effected consciousness while the interpretation is confronted with the ontological model of health. In the initial horizon we find the understanding of the motion of health and the extension towards text materials which is undertaken by Pascal’s Penseés. to open up the perspective and be able to project the horizon of the text. In the encounter with the text, the core content will first be discussed in an interpretative part after which the understanding gained will be summarized into new abductive assumptions. On the basis of Gadamer’s emphasis on the applications of the interpretations, the merging of the horizons will identify health as something desired by man, what he is and what he wants to accomplish. The creation of health is the reason of the heart, and on the basis of what man wants to confide in, the rise of health will be established. The totality of greatness and baseness of man is achieved by the accomplishment of health. That man owns spiritual devotedness means health whereas unhealthy means that he is insecure of his character and leads a life with ill-considered amusements. When according to Pascal, man’s desires and thoughts are joined in the heart, a connecting relation will arise. Hence the spiritual edification that man will fail to secure if he puts too much of his confidence in transient reason is included, something that is insufficient when it comes to understand the meaning of health.

The role of business information and knowledge in sales steering

The objective of this study is to find out how sales management can be optimally supported with business information and knowledge. The first chapters of the study focus on theoretical literature about sales planning, sales steering, business intelligence, and knowledge management. The empirical part of the study is a case study for which the material was collected through interviews with the selected people of the company. The findings from the interviews were analyzed, and possible suggestions for solving the problems were made. The case study revealed that sales management requires a multitude of metrics and reports to steer the sales to the desired direction. The information sources can be internal and external, and the optimal solution for satisfying the information needs is a combination of both of these. The simple information should be turned into knowledge by merging the intellectual assets with the information from the firm’s transaction processing systems, in order to promote organizational learning and effective decision-making.

Gross anatomical features of the oropharyngeal cavity of the ostrich (Struthio camelus)

Most descriptions of the ostrich oropharynx and oesophagus are superficial and supply little meaningful morphological data. The aim of this investigation is describe the ostrich oropharingeal cavity, in order to supply the deficiency of macroscopic data about this important animal. Five heads of 12 to 14-month-old ostriches of either sex were anatomically dissected to expose the oropharynx. The ostrich oropharynx was "bell-shaped" composed by the maxillary and mandibular ramphoteca. The roof and floor presented two distinct regions different in colour of the mucosa. The rostral region was pale pink contrasting to creamy-pink coloured caudal region. The median longitudinal ridge extended rostrally from the apex of the choana to the tip of the beak in the roof and it is clearly more prominent and rigid than the homolog in the floor that appeared thin and stretched rostrally, continuing caudally surrounding the tongue and the laryngeal mound eventually merging with the oesophageal mucosa. The floor was formed by the interramal region, tongue and laryngeal mound containing shield-shaped glottis. It can be concluded that the present study, in addition to confirming the basic features of the oropharynx previously described for the ostrich, clarified the contradictory information presented in the literature and also provided new, unreported morphological data, some of which may be important when studying nutrition and health in these birds.

Integrating the export distribution channels after an acquisition

This thesis is based on studying integration synergies in a merger or acquisition situation with the interest in distribution channel integration. M&As seem to be forever popular and nowadays companies often use them as a certain kind of strategy to develop their business. M&As have attracted research for decades and also distribution in M&As has been found interesting. Moreover, research often concentrates to the horizontal M&A´s potential synergies that emerge in the integration process and so is the case also in this study as the core issue is to study the integration of the distribution channels and its potential synergies. This study concentrates on a single case, an acquisition which took place in 2011. The case consists of two Finnish companies operating in the same business field. Both of the companies are very export orientated, which gives this study its export view. As the companies operate in the same field this acquisition falls into the categorization of horizontal acquisition. The objective of the thesis is to study how the export channels could be integrated after an acquisition? This research question is divided again to three sub-questions asking how the distribution channels of the acquirer and acquired company are organized, what is pursued by the post-acquisition distribution channel integration and what are the integration challenges especially from the logistics point-of-view. The framework was built from the basis of the literature used in this thesis. The framework combines M&A process and distribution channels to a one united model which presents the progress of this thesis. The study was carried out as a qualitative research and as a holistic single case study. The data used in the research includes two interviews, other material from the case companies and also material of the companies collected by the author independently from different sources. There were many motives for the acquisition as usual. From the research results one can find that the integration process is still very ongoing and the synergies have not yet been fully discovered but also they are there to be found. The concentration of the research was in the export distribution which proved to be meaningful since the exports markets of the case companies were found to be quite complementary. The research results brought up also other issues concerning the post-acquisition integration process rather than the distribution channels and export. M&As are always a risky business. The final result can never be predicted. No matter how good the merging companies look on paper the practice is not the same. The acquisition process of this case has not ended yet and there lies potential synergy benefits to be discovered if enough effort is used to go through the process right.

Ecophysiology

An attempt to delineate rather than to precisely define what we mean by "ecophysiology" is based on a brief historical overview of what eventually led to development of instrumentation and sampling strategies for analyses that allow description of physiological performance in the field. These techniques are surveyed. Ecophysiology originally is aut-ecology dedicated to the behaviour of individual plants, species or higher taxa, viz. "physiotypes", in particular habitats. Examples of ecophysiological diversity are developed, which illustrate gradual merging with more integrative considerations of functions and dynamics of habitats or ecosystems, i.e. a trend of research towards physiological syn-ecology. The latter is exemplified by studies with comparisons of a variety of morphotypes and physiotypes within a given habitat or ecosystem and across a range of habitats or ecosystems. The high demand and complexity as well as the excitement of ecology and ecophysiology arise from the quest to cover all conditions of the existence of organisms according to Ernst Haeckel's original definition of "ecology".
