Challenges of Post-acquisition Integration

Työ käsittelee suomalaisen kemianalan yrityksen Yhdysvalloissa tekemää yritysostoa. Tarkastelun kohteena on yritysoston jälkeinen integraatio erityisesti kulttuurin näkökulmasta. Ongelma on jaettu kahteen suurempaan osakokonaisuuteen: kulttuurierojen analysointiin sekä mahdollisten muiden ongelma-alueiden kartoittamiseen. Kulttuuri on jaettu työssä neljään tasoon. Koska kyseessä on kansainvälinen liiketoiminta, laajimmasta tasosta, kansallisesta kulttuurista on erotettu omaksi käsitteekseen liiketoimintatavat tietyssä maassa. Lisäksi tarkastellaan teollisuudenalan kulttuuria ja yrityskulttuuria. Näitä kulttuurin eri dimensioita on lähestytty empiirisessä osassa lähinnä haastattelujen avulla. Kultuurierojen lisäksi muita huomioitavia seikkoja Yhdysvalloissa tehtävien yritysostojen integraatiossa ovat mm. riittävä ja selkeä kommunikonti, etukäteissuunnitelmat ja –tutkimukset, päätöksenteon ja organisaatiorakenteen erilaisuus sekä asianajajien merkittävä asema amerikkalaisessa yhteiskunnassa. Tulokset analysoitiin kyselystä, joka lähetettiin niille suomalaisille yrityksille, jotka vuoden 1990 jälkeen olivat tehneet yritysostoja Yhdysvalloissa.

Johdon yritysoston onnistumisen tukeminen pääomasijoitusyhtiön post-buyout toiminnan avulla

Tutkielman tavoitteena on analysoida, miten pääomasijoitusyhtiö voi post-buyout toiminnallaan tukea sijoituksensa onnistumista erilaisissa johdon yritysostotapauksissa. Tutkielmassa rakennetaan teoreettinen viitekehys, jonka avulla pääomasijoitusyhtiö voi tukea sijoituksensa arvon säilymistä ja toisaalta lisäarvon syntymistä. Tätä viitekehystä tarkennetaan ja testataan empiirisellä aineistolla, joka koostuu suomalaisen pääomasijoitusyhtiön ja sen neljän johdon yritysoston läpikäyneen kohdeyrityksen haastatteluista sekä pääomasijoitusyhtiön tuottamasta kirjallisesta materiaalista. Teorian ja empiirisen materiaalin perusteella johdon yritysoston onnistu-minen on usein subjektiivista sekä suhteellista suunniteltuun irtautumistapaan nähden. Joissakin tapauksissa jo pelkkä pääomasijoittajan mukaantulo voi vaikuttaa positiivisesti kohdeyrityksen riskinottoon ja siten pääomasijoitusyhtiön post-buyout toiminnan onnistumiseen.

Estimación de funciones no lineales en mezclas post-no lineales

This paper proposes a new method for blindly inverting a nonlinear mapping which transforms a sum of random variables. This is the case of post-nonlinear (PNL) source separation mixtures. The importance of the method is based on the fact that it permits to decouple the estimation of the nonlinear part from the estimation of the linear one. Only the nonlinear part is inverted, without considering on the linear part. Hence the initial problem is transformed into a linear one that can then be solved with any convenient linear algorithm. The method is compared with other existing algorithms for blindly approximating nonlinear mappings. Experiments show that the proposed algorithm outperforms the results obtained with other algorithms and give a reasonably good linearized data

Post-mortem determination of insulin using chemiluminescence enzyme immunoassay: preliminary results.

Insulin determination in blood sampled during post-mortem investigation has been repeatedly asserted as being of little diagnostic value due to the rapid occurrence of decompositional changes and blood haemolysis. In this study, we assessed the feasibility of insulin determination in post-mortem serum, vitreous humour, bile, and cerebrospinal and pericardial fluids in one case of fatal insulin self-administration and a series of 40 control cases (diabetics and non-diabetics) using a chemiluminescence enzyme immunoassay. In the case of suicide by insulin self-administration, insulin concentrations in pericardial fluid and bile were higher than blood clinical reference values, though lower than post-mortem serum concentration. Insulin concentrations in vitreous (11.50 mU/L) and cerebrospinal fluid (17.30 mU/L) were lower than blood clinical reference values. Vitreous insulin concentrations in non-diabetic control cases were lower than the estimated detection limit of the method. These preliminary results tend to confirm the usefulness of insulin determination in vitreous humour in situations of suspected fatal insulin administration. Additional findings pertaining to insulin determination in bile, pericardial, and cerebrospinal fluid would suggest that analysis performed in post-mortem serum and injection sites could be complemented, in individual cases, by investigations carried out in alternative biological fluids. Lastly, these results would indicate that analysis with chemiluminescence enzyme immunoassay may provide suitable data, similar to analysis with liquid chromatography-tandem mass spectrometry (LC-MS/MS) and immunoradiometric assay, to support the hypothesis of insulin overdose.

High doses of onabotulinumtoxinA in post-stroke spasticity: a retrospective analysis.

We retrospectively evaluated the efficacy and safety of high doses of onabotulinumtoxinA (from 600 to 800 units) in 26 patients affected by upper and/or lower limb post-stroke spasticity. They were assessed before, 30 and 90 days after treatment. We observed a significant muscle tone reduction and a significant functional improvement (assessed with the Disability Assessment Scale). No adverse events were reported. In our retrospective analysis the treatment with high doses of onabotulinumtoxinA showed to be effective and safe.

Improving the Prediction of Spontaneous and Post-thrombolytic Recanalization in Ischemic Stroke Patients.

BACKGROUND: Endovascular treatment for acute ischemic stroke patients was recently shown to improve recanalization rates and clinical outcome in a well-defined study population. Intravenous thrombolysis (IVT) alone is insufficiently effective to recanalize in certain patients or of little value in others. Accordingly, we aimed at identifying predictors of recanalization in patients treated with or without IVT. METHODS: In the observational Acute Stroke Registry and Analysis of Lausanne (ASTRAL) registry, we selected those stroke patients (1) with an arterial occlusion on computed tomography angiography (CTA) imaging, (2) who had an arterial patency assessment at 24 hours (CTA/magnetic resonance angiography/transcranial Doppler), and (3) who were treated with IVT or had no revascularization treatment. Based on 2 separate logistic regression analyses, predictors of spontaneous and post-thrombolytic recanalization were generated. RESULTS: Partial or complete recanalization was achieved in 121 of 210 (58%) thrombolyzed patients. Recanalization was associated with atrial fibrillation (odds ratio , 1.6; 95% confidence interval, 1.2-3.0) and absence of early ischemic changes on CT (1.1, 1.1-1.2) and inversely correlated with the presence of a significant extracranial (EC) stenosis or occlusion (.6, .3-.9). In nonthrombolyzed patients, partial or complete recanalization was significantly less frequent (37%, P < .01). The recanalization was independently associated with a history of hypercholesterolemia (2.6, 1.2-5.6) and the proximal site of the intracranial occlusion (2.5, 1.2-5.4), and inversely correlated with a decreased level of consciousness (.3, .1-.8), and EC (.3, .1-.6) and basilar artery pathology (.1, .0-.6). CONCLUSIONS: Various clinical findings, cardiovascular risk factors, and arterial pathology on acute CTA-based imaging are moderately associated with spontaneous and post-thrombolytic arterial recanalization at 24 hours. If confirmed in other studies, this information may influence patient selection toward the most appropriate revascularization strategy.

Animals in an Urban Context. A Zooarchaeological study of the Medieval and Post-Medieval town of Turku

The aim of this study is to explore the role and importance of different animal species in Turku through an analysis of osteological data and documentary evidence. The osteological material used in this study is derived from two town plots in Turku dating from the 13th century to the 19th century. The osteological material deposited in Turku represents animals bred both in the town and in the surrounding landscape. Animal husbandry in SW-Finland can also be examined through a number of historical documents. The importance of animals in Turku and its hinterland are closely connected and therefore the roles of the animals in both urban and rural settings are examined. The study has revealed the complexity of the depositional patterns in medieval and post-medieval Turku. In the different areas of Turku, characteristic patterns in the osteological material and different deposit types were evident. These patterns are reflections of the activities and therefore of the lifestyles practiced in Turku. The results emphasise the importance of context- awareness in the study of material culture from archaeological sites. Both the zooarchaeological and historical sources indicate that cattle were important in animal husbandry in Turku from the Middle Ages up to the 19th century. Sheep were the second most common species. When taking into consideration the larger size of cattle, the dominance of these animals when it come to meat consumption seems clear even in those phases where sheep bones are more abundant. Pig is less abundant in the material than either cattle or sheep and their importance for subsistence was probably fairly modest, albeit constant. Goats were not abundant in the material. Most of the identified goat bones came from low utility body parts (e.g. skulls and lower extremities), but some amount of goat meat was also consumed. Wild species were of minor importance when it came to consumption practices in Turku. The changes in Turku’s animal husbandry patterns between the medieval and post medieval periods is reflected in the change in age of the animals slaughtered, which was part of a wider pattern seen in North- and Central Europe. More mature animals are also present in the assemblages. This pattern is related to the more pronounced importance of cattle as a manure producer and a draught animal as a result of the intensification of crop cultivation. This change seems to occur later in Finland than in the more Southerly regions, and indeed it did not necessarily take hold in all parts of the country.

Aesthetic Breast Augmentation Mastopexy Followed by Post-surgical Pyoderma Gangrenosum (PSPG): Clinic, Treatment, and Review of the Literature.

INTRODUCTION: Pyoderma gangrenosum (PG) is a rare autoinflammatory neutrophilic ulcerative skin disease, often developing after a trauma or surgical wounds. In the literature there are several reports of post-surgical PG (PSPG) of the breast. The authors of this article experienced an impressive case of PSPG after an aesthetic breast augmentation mastopexy. PSPG is a rare but severe complication in this elective aesthetic surgical procedure. METHOD: A systematic review of the literature was performed, focusing on PSPG after aesthetic breast surgery (augmentation mammoplasty/mastopexy). The online databases Pubmed, Medline, and Cochrane were used and additionally a Google© search was conducted. We compared the data obtained from a systematic literature review to an index case of PSPG after esthetic augmentation mammoplasty. RESULTS: The literature search identified seven articles describing eight cases of PSPG after aesthetic breast surgery. In four of these cases augmentation mammoplasty had been carried out, in two cases mastopexy and in two cases augmentation mammoplasty and mastopexy (augmentation mastopexy). The patient we treated and describe in this paper underwent an augmentation mastopexy outside our clinic. Eight patients suffered from local disease, at the site of surgical wounds, one patient had disseminated disease. Leukocytosis was present in five cases (out of nine). Eight patients had received corticosteroid treatment, one patient refused such treatment. The duration of corticosteroid treatment was on average for 41 days (range 21-60 days). In all cases, the areola had been spared. Complete healing of PSPG was observed on average after 5 months (range 1.5 months-1 year). DISCUSSION: PSPG of the breast after aesthetic breast surgery is rare, but every plastic surgeon should consider this possibility, especially if skin disease develops post-surgery, mimicking wound infection that does not respond to broad-spectrum antibiotic treatment. CONCLUSION: Although the literature does not recommend this step, implant removal is recommended by the authors because bacterial wound infection normally cannot be ruled out definitely in the early stages of disease. Additional surgical intervention should be limited to the absolute necessary and performed only under adequate systemic immunosuppressive therapy.
