Kuntaorganisaation henkilöstöraportoinnin kehittäminen, case: Lappeenrannan kaupunki

Tämän tutkimuksen tarkoituksena on tutkia Lappeenrannan kaupungin henkilöstöraportointia ja auttaa sen kehittämistyössä siten, että se vastaisi paremmin toimialojen käytännön henkilöstöjohdollisia tarpeita. Nykyisellään henkilöstöstä tuotettua informaatiota voidaan pitää toimialojen johdon näkökulmasta puutteellisena ja vanhentuneena. Tavoitteena on täten auttaa kaupunkia kehittämään raportointityövälineitään vastaamaan nykyistä paremmin reaaliaikaisiin johdollisiin tarpeisiin kartoittamalla eri toimialojen henkilöstöraportointiin liittyviä toiveita. Teoriaosassa käsitellään henkisen ja aineettoman pääoman ulottuvuuksia, henkilöstövoimavarojen johtamisen toimintakenttää sekä henkilöstövoimavarojen raportointia. Empiirisessä osassa keskitytään Lappeenrannan kaupunkiin, sen henkilöstöraportoinnin nykytilaan ja mahdollisiin kehittämisehdotuksiin. Luonteeltaan tutkimusta voidaan pitää laadullisena tapaustutkimuksena, joka sisältää sekä deskriptiivisiä että normatiivisia piirteitä. Tutkimuksen perusteella havaitaan, ettei henkilöstöraportointi nykyisellään täysin vastaa esimiesten tarpeita, vaan sitä tulisi kehittää sekä sisällöllisesti että käytettyjen raportointivälineiden osalta joustavammaksi toimialojen erityispiirteitä huomioivaksi kokonaisuudeksi.

Tavoitevarastoarvojen määrittäminen uusille tuotteille - case: päivittäistavarakaupan yritys

Tämän tutkielman tarkoituksena oli löytää keinoja uusien tuotteiden tavoitevarastoarvojen määrittämisen helpottamiseksi case-yrityksessä. Ongelma on seurausta siitä, ettei uusille tuotteille ole saatavissa kysyntädataa. Oikeelliset tavoitevarastoarvot on tärkeitä case-yritykselle hävikin minimoimisen ja erityisesti asiakastyytyväisyyden vuoksi. Tutkittavaa aihetta lähestyttiin päivittäistavarakaupan strategisten menestystekijöiden sekä varastonhallinnan kautta. Teoriaosuuden pohjalta toteutettiin empiirinen osio, jossa etsittiin case-yrityksen kahden tuoteryhmän kysyntää selittäviä tekijöitä paneeliregression avulla. Ensin kuitenkin tutkittiin tuoteryhmien yleistä kysynnän rakennetta erilaisten kysyntäkuvaajien sekä korrelaatiomatriisien avulla. Tavoitevarastoarvoon eniten vaikuttava tekijä on kysyntä. Brändi ja hinta muodostuivat puolestaan vahvimmiksi kysyntää määrittäviksi muuttujiksi. Kysyntää arvioitaessa muut sitä nostavat muuttujat tulee aina miettiä tapauskohtaisesti. Mehukeitoilla kysyntää nostivat eniten vahva brändi ja suuri pakkauskoko. Juustoraasteilla puolestaan alhainen hinta ja pieni pakkauskoko olivat keskeisimmät myyntiin vaikuttavat tekijät. Tuoteryhmien muut kysyntää nostavat ominaisuudet olivat samoja, kuin tuoteryhmän suosituimmilla tuotteilla.

The nature of communication structures of university students in an international web-based computer-supported collaborative learning (CSCL) course

Communication, the flow of ideas and information between individuals in a social context, is the heart of educational experience. Constructivism and constructivist theories form the foundation for the collaborative learning processes of creating and sharing meaning in online educational contexts. The Learning and Collaboration in Technology-enhanced Contexts (LeCoTec) course comprised of 66 participants drawn from four European universities (Oulu, Turku, Ghent and Ramon Llull). These participants were split into 15 groups with the express aim of learning about computer-supported collaborative learning (CSCL). The Community of Inquiry model (social, cognitive and teaching presences) provided the content and tools for learning and researching the collaborative interactions in this environment. The sampled comments from the collaborative phase were collected and analyzed at chain-level and group-level, with the aim of identifying the various message types that sustained high learning outcomes. Furthermore, the Social Network Analysis helped to view the density of whole group interactions, as well as the popular and active members within the highly collaborating groups. It was observed that long chains occur in groups having high quality outcomes. These chains were also characterized by Social, Interactivity, Administrative and Content comment-types. In addition, high outcomes were realized from the high interactive cases and high-density groups. In low interactive groups, commenting patterned around the one or two central group members. In conclusion, future online environments should support high-order learning and develop greater metacognition and self-regulation. Moreover, such an environment, with a wide variety of problem solving tools, would enhance interactivity.

Uuteen organisaatioon rakennettavan kustannuslaskentajärjestelmän sertifioiminen valtionhallinnossa: Case Maanmittauslaitos

Työn lähtökohtana oli tieto siitä, että Valtiontalouden tarkastusvirasto (VTV) on lähtenyt tarjoamaan kustannuslaskentajärjestelmien sertifiointeja valtion virastoille ja laitoksille. Ensimmäisenä tavoitteena oli selvittää, mitä kustannuslaskentajärjestelmien sertifioiminen valtionhallinnossa tarkoittaa. Työn toisena tavoitteena oli selvittää, miten Maanmittauslaitoksen kustannuslaskenta muuttuu vuoden 2014 vaihteessa tapahtuvan organisaatiouudistuksen johdosta, ja miten ja milloin tämä uusi kustannuslaskentajärjestelmä voidaan sertifioida. Diplomityö toteutettiin tapaustutkimuksena ja empiirinen aineisto kerättiin kvalitatiivisin menetelmin tekemällä organisaation sisäisiä ja ulkoisia haastatteluja. Maanmittauslaitoksen lisäksi haastateltavat osapuolet olivat VTV, Ernst & Young, sertifiointiprosessin lähes läpikäyneen Riista- ja kalatalouden tutkimuslaitoksen entinen ja nykyinen talouspäällikkö, Maa- ja metsätalousministeriö ja Valtiokonttori. Haastatteluiden lisäksi valtion virastoilta ja laitoksilta kysyttiin ovatko he kuulleet VTV:n tarjoamasta sertifiointipalvelusta ja ovatko he kiinnostuneita tästä kyseisestä palvelusta. Työn tuloksista käy ilmi, että VTV:n palvelu etenee samalla tavalla kuin mikä tahansa muu sertifiointiprosessi. VTV:n palvelu eroaa kuitenkin jonkin verran sertifioinnin perusrakenteesta, koska kustannuslaskentajärjestelmien tapauksessa ei ole laadittu yleisiä standardeja kustannuslaskennalle. Tämän vuoksi perusrakenteessa ei ole ollenkaan standardin omistajaa. Standardin omistajan paikalle sijoittuvat laki valtion talousarviosta ja asetus valtion talousarviosta. Maanmittauslaitoksen kustannuslaskenta muuttuu organisaatiouudistuksen myötä odotettua enemmän. Uuden organisaatiorakenteen vuoksi kustannuksia ei tarvitse vyöryttää toimintayksiköille, tulosyksiköille ja vastuualueille. Kustannukset vyörytetään jatkossa vain tuotteille ja projekteille. Maanmittauslaitoksen kannattaa sertifioida uusi kustannuslaskentajärjestelmänsä vuonna 2014, vaikka seuraavien vuosien aikana on tiedossa uusia muutoksia sekä organisaatioon, että tietojärjestelmiin. Ennen varsinaista tarkastusta Maanmittauslaitoksen kustannuslaskentajärjestelmä kuvattiin uudelleen.

Elevers läs- och skrivförmåga över tid : en longitudinell kohortstudie av läsförståelse och stavning i årskurs 1-6 i en finlandssvensk skola

Reports have shown that a growing number of students are leaving school without adequate reading and writing skills. At the same time, finnish children have improved in reading lit-eracy over the past decade. The school´s primary mission is to support student´s reading and writing development and follow it over time. Not only individual students´development has to be followd over time, as seen in this study, to be able to plan interventions. The purpose of this licentiate thesis is to study how the results in grades 1–6 exhibit in reading compre-hension and spelling over time in a school for the Swedish-speaking minority in Finland. Even gender differences in reading comprehension and spelling are being examined, as well as students with low performance. The data collection has been done during a period of twelwe years, 1997–2009, where data from practically every two years has been used for this study. Results are reported for the years 1997, 2000, 2001, 2003, 2007 and 2009. The measuring instruments are standardized and normative tests in reading comprehension and spelling. The same instruments were used all of the years. The number of students was 1 037 and when possible, students partici-pated more than once. There was a minimal loss of data. The groups of students mostly came from urban districts, and a smaller number came from rural districts. Students with special needs were included in the group, but none of the students in special units participat-ed. The results show that the skills in reading comprehension and spelling haven´t changed appreciably over time. The trend shows slightly positive or unchanged direction except in spelling in grade 1 and reading comprehension in grade 5 where the trend is slightly nega-tive. The most obvious change can be noticed over time in reading comprehension in grade 2, where performance has improved significantly. Significant differences between boys´and girls´performances occur some years and in favor of the girls, but more often in spelling than in reading comprehension. In grade 4, there are no differences in results between boys and girls in any year, neither in reading comprehension nor in spelling, nor in grade 2 in reading comprehension. When the results shows gender differences, there are always differ-ences in both reading comprehension and spelling. Poor performances are also analyzed over time. Isolated reading comprehension difficulties were common for those who was performing poorly. In grade 2, as the only grade, most common was a double deficit in both reading comprehension and spelling, and in grade 4, most students who performed poorly had isolated difficulties in spelling. The amount of poor results varies over time, and no particular trend can be discerned. In grade 2, however, the poor results decreased over time, especially for the boys. Even in reading comprehension for grade 6 the amount of poor results, especially for the boys (10th percentile), has decreased over time, at least in the later years, while the poor results in-creased in spelling generally. In grade 4 the amount of poor results in spelling (10th perc.) seems to be reduced for the girls.

The duality of tactical thought : a study of how Swedish land forces' commanders view tactics in irregular warfare

This is a sociological study of the views of officers in the Swedish Army and its Amphibious Forces on tactics in Irregular Warfare (IW), in particular, Counterinsurgency (COIN). IW comprises struggles, where the military weaker part uses an indirect approach with smaller units and integrates the civilian and military dimensions in a violence spectrum including subversion, terrorism, Guerrilla Warfare and infantry actions. IW is the main armed warfare style in insurgencies. COIN is the combined political, military, economic, social and legal actions in counter insurgencies. Data has been collected by means of interviews with almost all (n =43) officers, who were either commanding battalions or rifle and manoeuvre companies while undergoing training for general warfare and international operations. The main theoretical and methodological inspiration is the traditional one for research on social fields, inaugurated by the French sociologist Pierre Bourdieu. The statistical technique used is Multiple Correspondence Analysis. As a background and context base, an inquiry inspired by the Begriffsgechichte (Conceptual History) tradition explores the genesis and development of understandings of the term Irregular Warfare. The research question is outlined as; “how can contemporary Swedish military thought on tactics in Irregular Warfare be characterized using descriptive patterns, mapped in relation to background factors and normative standards? The most significant findings are that there are two main opposing notions separating the officers’ views on tactics in Irregular Warfare: (1) a focus on larger, combat oriented and collectively operating military units versus smaller and larger, more intelligence oriented and dispersed operating units, and (2) a focus on military tasks and kinetic effects versus military and civilian tasks as well as “soft” effects. The distribution of these views can be presented as a two-dimensional space structured by the two axes. This space represents four categories of tactics, partly diverging from normative military standards for Counterinsurgency. This social space of standpoints shows different structural tendencies for background factors of social and cultural character, particularly dominant concerning military backgrounds, international mission experiences and civilian education. Compared to military standards for Counterinsurgency, the two tactical types characterized by a Regular Warfare mind-set stands out as counter-normative. Signs of creative thought on military practice and theory, as well as a still persistent Regular Warfare doxa are apparent. Power struggles might thus develop, effecting the transformation to a broadened warfare culture with an enhanced focus also on Irregular Warfare. The result does not support research results arguing for a convergence of military thought in the European transformation of Armed Forces. The main argument goes beyond tactics and suggests sociological analysis on reciprocal effects regarding strategy, operational art, tactics as well as leadership, concerning the mind-set and preferences for Regular, Irregular and Hybrid Warfare.

Modulation of fibronectin expression in the central nervous system of Lewis rats with experimental autoimmune encephalomyelitis

Fibronectin (FN), a large family of plasma and extracellular matrix (ECM) glycoproteins, plays an important role in leukocyte migration. In normal central nervous system (CNS), a fine and delicate mesh of FN is virtually restricted to the basal membrane of cerebral blood vessels and to the glial limitans externa. Experimental autoimmune encephalomyelitis (EAE), an inflammatory CNS demyelinating disease, was induced in Lewis rats with a spinal cord homogenate. During the preclinical phase and the onset of the disease, marked immunolabelling was observed on the endothelial luminal surface and basal lamina of spinal cord and brainstem microvasculature. In the paralytic phase, a discrete labelling was evident in blood vessels of spinal cord and brainstem associated or not with an inflammatory infiltrate. Conversely, intense immunolabelling was present in cerebral and cerebellar blood vessels, which were still free from inflammatory cuffs. Shortly after clinical recovery minimal labelling was observed in a few blood vessels. Brainstem and spinal cord returned to normal, but numerous inflammatory foci and demyelination were still evident near the ventricle walls, in the cerebral cortex and in the cerebellum. Intense expression of FN in brain vessels ascending from the spinal cord towards the encephalon preceded the appearance of inflammatory cells but faded away after the establishment of the inflammatory cuff. These results indicate an important role for FN in the pathogenesis of CNS inflammatory demyelinating events occurring during EAE.

Zinc accumulation in phosphate granules of Ucides cordatus hepatopancreas

Amorphous phosphate granules are present in vertebrate and invertebrate organisms. The functions attributed to these structures depend on their mineral contents and organic matrix composition. In the present study we have determined zinc concentrations in the hepatopancreas of the crab Ucides cordatus from regions contaminated with zinc, and the elemental composition of hepatopancreal phosphate granules. Organisms were collected from the contaminated areas of Sepetiba Bay (SB) and Guanabara Bay (GB), and from a non-contaminated area, Ribeira Bay (RB). The first two sites are located near the metropolitan region of Rio de Janeiro city, Brazil. Atomic absorption spectroscopy (AAS) showed a significant difference (P<0.05) for zinc concentration in the hepatopancreas from organisms collected at the contaminated sites GB (210 ± 20 µg/g dry weight) and SB (181 ± 16 µg/g dry weight) compared to the non-contaminated site RB (76 ± 14 µg/g dry weight). Phosphate granules isolated from hepatopancreatic tissue were studied by electron diffraction (ED), energy dispersive X-ray analysis (EDX) and electron spectroscopic imaging (ESI). ED of granules presented no diffraction spots, indicating that these structures are in an amorphous state, while EDX of granules isolated from a contaminated area contained P, Ca and Zn. Mg, Cl and Fe were also found in some of the spectra. ESI showed that O, P and Ca were colocalized in the mineralized layers of most granules observed. The correlation between the results obtained by AAS and those obtained by microanalytical techniques suggests that the hepatopancreatic granules of U. cordatus may be related to the phenomenon of heavy metal retention.

Evidence of hemispheric specialization in marmosets (Callithrix penicillata) using tympanic membrane thermometry

Recent studies have employed tympanic thermometry to assess lateralization of cognitive and emotional functions in primates. However, no studies using this technique have investigated the possibility of hemispheric specialization in New World monkeys. Therefore, the aim of the present study was to investigate tympanic membrane (TM) temperature asymmetries and their possible correlation with stress responses in marmosets (Callithrix penicillata). Infrared TM thermometry was completed bilaterally in 24 animals (14 males and 10 females) during a stressful situation of capture and restraint. There were no significant differences between gender. A significant negative correlation was observed between TM temperature of the right ear and the number of captures (r = -0.633; P<0.001). Subjects with a more frequent previous history of captures (5 to 9 captures; N = 11) showed lower TM temperature when compared to those with fewer previous captures (1 to 4 captures; N = 13). No differences were observed for the left TM temperature. These results suggest that under intense emotional challenge (capture and restraint) there is a stronger activation of the neural structures situated in the right brain hemisphere. Taken together, the data reveal for the first time evidence of hemispheric specialization in emotional physiological processing in a New World monkey.

Thymocyte migration: an affair of multiple cellular interactions?

Cell migration is a crucial event in the general process of thymocyte differentiation. The cellular interactions involved in the control of this migration are beginning to be defined. At least chemokines and extracellular matrix proteins appear to be part of the game. Cells of the thymic microenvironment produce these two groups of molecules, whereas developing thymocytes express the corresponding receptors. Moreover, although chemokines and extracellular matrix can drive thymocyte migration per se, a combined role for these molecules appears to contribute to the resulting migration patterns of thymocytes in their various stages of differentiation. The dynamics of chemokine and extracellular matrix production and degradation is not yet well understood. However, matrix metalloproteinases are likely to play a role in the breakdown of intrathymic extracellular matrix contents. Thus, the physiological migration of thymocytes should be envisioned as a resulting vector of multiple, simultaneous and/or sequential stimuli involving chemokines, adhesive and de-adhesive extracellular matrix proteins, as well as matrix metalloproteinases. Accordingly, it is conceivable that any pathological change in any of these loops may result in the alteration of normal thymocyte migration. This seems to be the case in murine infection by the protozoan parasite Trypanosoma cruzi, the causative agent of Chagas' disease. A better knowledge of the physiological mechanisms governing thymocyte migration will provide new clues for designing therapeutic strategies targeting developing T cells.

Hypotrophy of conduit artery walls of the offspring of nitric oxide-defective rats

The objective of the present study was to investigate the structure of the arterial walls of the offspring stemming from nitric oxide (NO)-defective hypertensive parents. The parents were treated with N G-nitro-L-arginine methyl ester (40 mg kg-1 day-1) for 5 weeks. Blood pressure was measured noninvasively in six 30-day-old rats and nine age-matched controls. The cardiovascular system was perfused with glutaraldehyde at 120 mmHg. The thoracic aorta and carotid artery were processed for electron microscopy, and geometry was determined by light microscopy. Endothelial cells, smooth muscle cells (SMC) and extracellular matrix (ECM) were determined by the point counting method in electron micrographs of the carotid artery. The blood pressure of experimental offspring was 150.0 ± 2.3 vs 104.6 ± 2.1 mmHg (P < 0.01) for the controls and their heart/body weight ratio of 3.9 ± 0.1 vs 4.4 ± 0.2 (P < 0.05) for the controls indicated cardiac hypotrophy. The wall thickness (tunica intima and media) of the thoracic aorta and carotid artery of experimental offspring was decreased to 78.9% (P < 0.01) and 83.8% (P < 0.01), respectively, compared to controls, as confirmed by a respective cross-sectional area of 85.3% (P < 0.01) and 84.1% (P < 0.01). The wall thickness/inner diameter ratio was reduced to 75% (P < 0.01) in the thoracic artery and to 81.5% (P < 0.01) in the carotid artery. No change in endothelial cell volume density or ECM was observed in the tunica intima of the carotid artery, and SMC volume density was lower in the tunica media (37.6 ± 0.9 vs 44.7 ± 1.1% for controls, P < 0.01), indicating compromised SMC development. Interference with arginine metabolism, a decrease in NO, and other factors are possible mechanisms underlying the structural alterations of the cardiovascular system of offspring from NO-defective hypertensive rats.

Gene expression in IFN-gamma-activated murine macrophages

Macrophages are critical for natural immunity and play a central role in specific acquired immunity. The IFN-gamma activation of macrophages derived from A/J or BALB/c mice yielded two different patterns of antiviral state in murine hepatitis virus 3 infection, which were related to a down-regulation of the main virus receptor. Using cDNA hybridization to evaluate mRNA accumulation in the cells, we were able to identify several genes that are differently up- or down-regulated by IFN-gamma in A/J (267 and 266 genes, respectively, up- and down-regulated) or BALB/c (297 and 58 genes, respectively, up- and down-regulated) mouse macrophages. Macrophages from mice with different genetic backgrounds behave differently at the molecular level and comparison of the patterns of non-activated and IFN-gamma-activated A/J or BALB/c mouse macrophages revealed, for instance, an up-regulation and a down-regulation of genes coding for biological functions such as enzymatic reactions, nucleic acid synthesis and transport, protein synthesis, transport and metabolism, cytoskeleton arrangement and extracellular matrix, phagocytosis, resistance and susceptibility to infection and tumors, inflammation, and cell differentiation or activation. The present data are reported in order to facilitate future correlation of proteomic/transcriptomic findings as well as of results obtained from a classical approach for the understanding of biological phenomena. The possible implication of the role of some of the gene products relevant to macrophage biology can now be further scrutinized. In this respect, a down-regulation of the main murine hepatitis virus 3 receptor gene was detected only in IFN-gamma-activated macrophages of resistant mice.

Multicellular spheroids of bone marrow stromal cells: a three-dimensional in vitro culture system for the study of hematopoietic cell migration

Cell fate decisions are governed by a complex interplay between cell-autonomous signals and stimuli from the surrounding tissue. In vivo cells are connected to their neighbors and to the extracellular matrix forming a complex three-dimensional (3-D) microenvironment that is not reproduced in conventional in vitro systems. A large body of evidence indicates that mechanical tension applied to the cytoskeleton controls cell proliferation, differentiation and migration, suggesting that 3-D in vitro culture systems that mimic the in vivo situation would reveal biological subtleties. In hematopoietic tissues, the microenvironment plays a crucial role in stem and progenitor cell survival, differentiation, proliferation, and migration. In adults, hematopoiesis takes place inside the bone marrow cavity where hematopoietic cells are intimately associated with a specialized three 3-D scaffold of stromal cell surfaces and extracellular matrix that comprise specific niches. The relationship between hematopoietic cells and their niches is highly dynamic. Under steady-state conditions, hematopoietic cells migrate within the marrow cavity and circulate in the bloodstream. The mechanisms underlying hematopoietic stem/progenitor cell homing and mobilization have been studied in animal models, since conventional two-dimensional (2-D) bone marrow cell cultures do not reproduce the complex 3-D environment. In this review, we will highlight some of the mechanisms controlling hematopoietic cell migration and 3-D culture systems.

Longitudinal brain volumetric changes during one year in non-elderly healthy adults: a voxel-based morphometry study

Previous cross-sectional magnetic resonance imaging (MRI) studies of healthy aging in young adults have indicated the presence of significant inverse correlations between age and gray matter volumes, although not homogeneously across all brain regions. However, such cross-sectional studies have important limitations and there is a scarcity of detailed longitudinal MRI studies with repeated measures obtained in the same individuals in order to investigate regional gray matter changes during short periods of time in non-elderly healthy adults. In the present study, 52 healthy young adults aged 18 to 50 years (27 males and 25 females) were followed with repeated MRI acquisitions over approximately 15 months. Gray matter volumes were compared between the two times using voxel-based morphometry, with the prediction that volume changes would be detectable in the frontal lobe, temporal neocortex and hippocampus. Voxel-wise analyses showed significant (P < 0.05, family-wise error corrected) relative volume reductions of gray matter in two small foci located in the right orbitofrontal cortex and left hippocampus. Separate comparisons for males and females showed bilateral gray matter relative reductions in the orbitofrontal cortex over time only in males. We conclude that, in non-elderly healthy adults, subtle gray matter volume alterations are detectable after short periods of time. This underscores the dynamic nature of gray matter changes in the brain during adult life, with regional volume reductions being detectable in brain regions that are relevant to cognitive and emotional processes.
