Searching for keys to successful post-merger integration : a longitudinal case-study following a public sector merger

Unsuccessful mergers are unfortunately the rule rather than the exception. Therefore it is necessary to gain an enhanced understanding of mergers and post-merger integrations (PMI) as well as learning more about how mergers and PMIs of information systems (IS) and people can be facilitated. Studies on PMI of IS are scarce and public sector mergers are even less studied. There is nothing however to indicate that public sector mergers are any more successful than those in the private sector. This thesis covers five studies carried out between 2008 and 2011 in two organizations in higher education that merged in January 2010. The most recent study was carried out two years after the new university was established. The longitudinal case-study focused on the administrators and their opinions of the IS, the work situation and the merger in general. These issues were investigated before, during and after the merger. Both surveys and interviews were used to collect data, to which were added documents that both describe and guide the merger process; in this way we aimed at a triangulation of findings. Administrators were chosen as the focus of the study since public organizations are highly dependent on this staff category, forming the backbone of the organization and whose performance is a key success factor for the organization. Reliable and effective IS are also critical for maintaining a functional and effective organization, and this makes administrators highly dependent on their organizations’ IS for the ability to carry out their duties as intended. The case-study has confirmed the administrators’ dependency on IS that work well. A merger is likely to lead to changes in the IS and the routines associated with the administrators’ work. Hence it was especially interesting to study how the administrators viewed the merger and its consequences for IS and the work situation. The overall research objective is to find key issues for successful mergers and PMIs. The first explorative study in 2008 showed that the administrators were confident of their skills and knowledge of IS and had no fear of having to learn new IS due to the merger. Most administrators had an academic background and were not anxious about whether IS training would be given or not. Before the merger the administrators were positive and enthusiastic towards the merger and also to the changes that they expected. The studies carried out before the merger showed that these administrators were very satisfied with the information provided about the merger. This information was disseminated through various channels and even negative information and postponed decisions were quickly distributed. The study conflicts with the theories that have found that resistance to change is inevitable in a merger. Shortly after the merger the (third) study showed disappointment with the fact that fewer changes than expected had been implemented even if the changes that actually were carried out sometimes led to a more problematic work situation. This was seen to be more prominent for routine changes than IS changes. Still the administrators showed a clear willingness to change and to share their knowledge with new colleagues. This knowledge sharing (also tacit) worked well in the merger and the PMI. The majority reported that the most common way to learn to use new ISs and to apply new routines was by asking help from colleagues. They also needed to take responsibility for their own training and development. Five months after the merger (the fourth study) the administrators had become worried about the changes in communication strategy that had been implemented in the new university. This was perceived as being more anonymous. Furthermore, it was harder to get to know what was happening and to contact the new decision makers. The administrators found that decisions, and the authority to make decisions, had been moved to a higher administrative level than they were accustomed to. A directive management style is recommended in mergers in order to achieve a quick transition without distracting from the core business. A merger process may be tiresome and require considerable effort from the participants. In addition, not everyone can make their voice heard during a merger and consensus is not possible in every question. It is important to find out what is best for the new organization instead of simply claiming that the tried and tested methods of doing things should be implemented. A major problem turned out to be the lack of management continuity during the merger process. Especially problematic was the situation in the IS-department with many substitute managers during the whole merger process (even after the merger was carried out). This meant that no one was in charge of IS-issues and the PMI of IS. Moreover, the top managers were appointed very late in the process; in some cases after the merger was carried out. This led to missed opportunities for building trust and management credibility was heavily affected. The administrators felt neglected and that their competences and knowledge no longer counted. This, together with a reduced and altered information flow, led to rumours and distrust. Before the merger the administrators were convinced that their achievements contributed value to their organizations and that they worked effectively. After the merger they were less sure of their value contribution and effectiveness even if these factors were not totally discounted. The fifth study in November 2011 found that the administrators were still satisfied with their IS as they had been throughout the whole study. Furthermore, they believed that the IS department had done a good job despite challenging circumstances. Both the former organizations lacked IS strategies, which badly affected the IS strategizing during the merger and the PMI. IS strategies deal with issues like system ownership; namely who should pay and who is responsible for maintenance and system development, for organizing system training for new IS, and for effectively run IS even during changing circumstances (e.g. more users). A proactive approach is recommended for IS strategizing to work. This is particularly true during a merger and PMI for handling issues about what ISs should be adopted and implemented in the new organization, issues of integration and reengineering of IS-related processes. In the new university an ITstrategy had still not been decided 26 months after the new university was established. The study shows the importance of the decisive management of IS in a merger requiring that IS issues are addressed in the merger process and that IS decisions are made early. Moreover, the new management needs to be appointed early in order to work actively with the IS-strategizing. It is also necessary to build trust and to plan and make decisions about integration of IS and people.

Long-term professional performance of minimally invasive surgery post-graduates

OBJECTIVE: to evaluate the contribution of a post-graduation program in surgeons professional careers. METHODS: participants were asked to answer a questionnaire with questions related to possible changes in their professional performance after the end of the course. RESULTS: forty-three (76.7%) of the 56 participants eligible for the study responded to the questionnaires. Most participants, 32 (74.4%), had previous contact with laparoscopic surgery; however, only 14 (32.5%) reported the experience as primary surgeon. The expectations on the course were reached or exceeded for 36 (83.7%) participants. Thirty-seven (86%) incorporated minimally invasive procedures in their daily surgical practice, 37 (86%) reported improvements in their income above 10% and 12% reported income increase of over 100%, directly related to their increase of laparoscopic activity. CONCLUSION: the program in minimally invasive surgery provides a high level of satisfaction to its participants, enables them to perform more complex technical procedures, such as sutures, and improves their professional economic performance.

Associated factors to empyema in post-traumatic hemotorax

ABSTRACTObjective:to analyze the associated factors with empyema in patients with post-traumatic retained hemothorax.Methods:prospective observational study. Data were collected in patients undergoing PD during emergency duty. Variables analyzed were age, sex, mechanism of injury, side of the chest injury, intrathoracic complications of RH, laparotomy, specific injuries, rib fractures, trauma scores, days to diagnosis, diagnostic method of RH, primary indication of PD, initial volume drained, length of the first tube removal, surgical procedure. Cumulative incidence of empyema, pneumonia and pulmonary contusion and the proportion of patients with empyema or without empyema in each category of each variable analyzed were obtained.Results: the cumulative incidence of PD among trauma patients was 1.83% and the RH among those with PD was 10.63%. There were 20 cases of empyema (32.8%). Most were male in the age from 20 to 29, victims of injury by firearm on the left side of the thorax. The incidence of empyema in patients with injury by firearms was lower compared to those with stab wound or blunt trauma; higher among those with drained volume between 300 and 599 ml. The median hospital lenght of stay was higher among those with empyema.Conclusion:the incidence of PD was 1.83% and RH was 10.63%, these results are consistent with the low severity of the patients involved in this study and consistent with the literature. The incidence of empyema proved to be negatively associated with the occurrence of injury by firearms and positively associated with a drained volume between 300 and 599 ml, compared with lower or higher volumes.

Caracterização das lesões por Cysticercus bovis, na inspeção post mortem de bovinos, pelos exames macroscópico, histopatológico e pela reação em cadeia da polimerase (PCR)

Considerando a necessidade do conhecimento da cisticercose bovina e do aperfeiçoamento dos métodos de diagnóstico desta doença, objetivou-se verificar a ocorrência do Cysticercus bovis nos diversos locais anatômicos, tais como: cabeça, coração, esôfago, diafragma, língua, fígado e carcaça, examinados pelo Serviço de Inspeção Federal. O diagnóstico foi feito por macroscopia, microscopia e PCR com extração de DNA por fervura para a identificação do metacestóide. Dos 22043 bovinos abatidos, 713 (3,23%) estavam infectados. O coração foi o sítio anatômico mais afetado, com 1,90% (420/22043), seguido da cabeça, 1,11% (245/22043), do esôfago, 0,08% (18/22043), da carcaça, 0,07% (15/22043), do diafragma, 0,03% (7/22043), do fígado, 0,02% (5/22043) e da língua, 0,01% (3/22043). Dos cistos obtidos, 58,35% (416/713) estavam mortos e 41,65% (297/713), vivos. As diferenças entre os sítios anatômicos e a condição morfológica dos cistos foram significativas (p < 0,05). Dos 416 cistos mortos, 253 foram examinados por apresentarem características de: lesões nodulares firmes, brancacentas, com material amarelado, por vezes com aspecto calcário, no interior. O exame microscópico revelou granulomas comumente representados por centro necrótico e/ou mineralizado, envolto por histiócitos dispostos em paliçada, células gigantes multinucleadas, infiltrado misto, predominantemente de mononucleares, e fibrose. Por vezes, a periferia das lesões tinha características de tecido de granulação e mineralização em forma de lâminas lineares. Os restos parasitários foram identificados como um material hialino acelular, contendo elementos ovais e circulares, basofílicos, acidófilos e incolores, denominados corpúsculos calcários. Em algumas lesões foram observados raros corpúsculos, dispersos na reação inflamatória. Nódulos fibrosos, ricos em infiltrado linfóide ou crônico ativos, foram frequentemente visualizados. Dos cistos vivos examinados, 65% (13/20) foram positivos para C. bovis , confirmando o diagnóstico ambulatorial e a eficácia do método de PCR utilizado. Em virtude da positividade observada para C. bovis nos exames histopatológico e PCR, particularmente em fígado e esôfago, sugere-se que seja reformulado o artigo 176 do Regulamento de Inspeção Industrial e Sanitária de Produtos de Origem Animal, incluindo estes locais na rotina de inspeção nos matadouros.

Uso de métodos complementares na inspeção post mortem de carcaças com suspeita de tuberculose bovina

O objetivo foi utilizar métodos complementares de diagnóstico (histopatológicos, bacteriológicos e moleculares), no julgamento de lesões suspeitas de tuberculose observadas durante a inspeção post mortem de rotina em abatedouros. Foi acompanhado o abate e a inspeção de 41.193 bovinos, sadios ao exame ante mortem, em sete abatedouros no estado de Mato Grosso. Carcaças de 198 (0,48%) animais apresentaram lesões, sendo 182 (92,0%) classificadas como granulomatosas ou piogranulomatosas na avaliação histopatológica. Entretanto, na baciloscopia, não foi evidenciada a presença de bacilo álcool-ácido resistente (BAAR). Mycobacterium bovis foi isolado em três (1,5%) lesões, provenientes de linfonodos retrofaringeanos de bovinos com até três anos de idade. Quando usado a PCR múltipla (m-PCR) diretamente nos fragmentos de tecido, detectou-se a presença de DNA de M. bovis em 14 (7,0%) lesões, incluindo as três amostras identificadas na análise bacteriológica. O julgamento das lesões pelo exame macroscópico concordou em 93,0% (184/198) com os resultados obtidos por meio da PCR. A fim de evitar equívocos durante a avaliação, principalmente das lesões paucibacilares, como as encontradas neste estudo, recomenda-se a utilização de testes complementares rápidos e confirmatórios. A m-PCR, associada à inspeção post mortem de rotina, demonstrou ser uma técnica promissora para a vigilância da tuberculose bovina em abatedouros, contribuindo para o sucesso do programa de erradicação da tuberculose bovina.

Pre-and post-puberty physiological plasma oxytocin concentrations in male domestic cats (Felis silvestris catus)

The hormone oxytocin is released by the neuropituitary gland through stimulation of the neurons of the supraoptic and paraventricular nuclei of the hypothalamus. In order to determine the physiological concentrations of this hormone in domestic cats, blood samples were collected from 15 male animals (Felis silvestris catus) during the pre- and post-puberty periods (at four and eight months of age, respectively). Oxytocin determination was accomplished by radioimmunoassay. The average oxytocin concentrations measured in the pre- and post-puberty periods were 2.54±0.24 (μg/dL) and 2.53±0.28 (μg/dL), respectively, and there were no statistical differences between these measurements. Because there are few literature on the analysis of this hormone, especially in the case of male Felis silvestris catus, more studies on the influence of oxytocin on the physiology and reproduction of this species should be conducted under maintenance and situations of stress (such as transportation), and other routine events.

A interpretação das alterações encontradas na necropsia é uma etapa importante para o sucesso do diagnóstico final. Este trabalho tem como objetivo descrever e ilustrar os aspectos anatômicos, não lesões, artefatos, lesões sem significado clínico e alterações post mortem encontradas em suínos domésticos e selvagens. Além disso, também se recomenda técnicas de colheita de tecidos para o diagnóstico de doenças que acometem essa espécie. Os principais aspectos anatômicos e não lesões descritos são fímbrias linguais, quadrilátero esofágico, toro pilórico e demarcação do padrão lobular do fígado (sistema gastrintestinal); tonsilas do palato mole, tecido linfoide associado ao estômago, placas de Peyer do intestino delgado e dobras da margem do baço (sistema hematopoiético); mediastino proeminente do testículo e aréolas da placenta (sistema reprodutor); atelectasia pulmonar e apêndice decidual (feto); e glândulas carpais (sistema tegumentar). Os artefatos de eutanásia abordados são petéquias na superfície do pulmão e rim, falsa anemia por sangria, hemorragia subdural por concussão cerebral, pseudo-infartos do baço e aspecto cerebriforme do intestino delgado. As lesões de pouco significado clínico descritas são cistos renais, linfonodos com pigmento de ferro, papilomas e hemangiomas no escroto, ossos no mesentério e hiperemia da mucosa gástrica. As alterações post mortem comumente encontradas são livor mortis, músculos pálidos, pseudomelanose e líquido serosanguinolento nas cavidades torácica e abdominal em fetos.

Clinical, hematological, total plasma protein and fibrinogen parameters of magellanic penguins ( Spheniscus magellanicus ) pre- and post-rehabilitation

Abstract: Magellanic penguins (Spheniscus magellanicus) usually arrive in poor body conditions at Brazilian beaches during the winter. Hematology provides valuable information about clinical and immunity status of the animals. The aims of this study were to determine the hematologic, total plasma protein (TPP) and fibrinogen profiles of young and adult magellanic penguins in PROAMAR and CETAS-SC, relating these results with the state of health and survival possibility of the animals. In Paraná 14 animals were evaluated in pre and eight in post-rehabilitation and 29 animals were evaluated in Santa Catarina after rehabilitation. Before rehabilitation, all animals showed weakness. In hematological exams of these animals, we found that anemia was present in 83% of the penguins that died and 50% of those which survived. The heterophils/lymphocytes (H/L) ratio was 3.87±0.57 in animals that died, significantly higher than the average of 2.20±0.30 for animals that survived. These two parameters are useful to assess the survival possibility of animals to rehabilitation. The body condition score was positively correlated with hematocrit and TPP, and negatively correlated with H/L ratio. After rehabilitation, the values were similar to other animals of the family Spheniscidae, with averages ranging from 1.64 to 1.90x106 erythrocytes/μL; 43.38 to 48.80% of hematocrit; 12.45 to 13.52g/dL of hemoglobin; 8,684 to 14,011 leukocytes/μL; 4,767 to 8,041 heterophils/μL; 3,215 to 4,951 lymphocytes/μL; 95 to 655 eosinophils/μl; 179.8 to 277.9 monocytes/μL; 141 to 184.9 basophils/μL; and 1.26 to 1.74 of H/L ratio. These parameters can therefore be used as reference values and release parameters for young and adult Magellanic penguins in captivity on the rehabilitation centers.

An Inspection System to Identify Fatigue Damage on Steel-Bridge Structures

Crack formation and growth in steel bridge structural elements may be due to loading oscillations. The welded elements are liable to internal discontinuities along welded joints and sensible to stress variations. The evaluation of the remaining life of a bridge is needed to make cost-effective decisions regarding inspection, repair, rehabilitation, and replacement. A steel beam model has been proposed to simulate crack openings due to cyclic loads. Two possible alternatives have been considered to model crack propagation, which the initial phase is based on the linear fracture mechanics. Then, the model is extended to take into account the elastoplastic fracture mechanic concepts. The natural frequency changes are directly related to moment of inertia variation and consequently to a reduction in the flexural stiffness of a steel beam. Thus, it is possible to adopt a nondestructive technique during steel bridge inspection to quantify the structure eigenvalue variation that will be used to localize the grown fracture. A damage detection algorithm is developed for the proposed model and the numerical results are compared with the solutions achieved by using another well know computer code.

Model based analysis of the post-combustion calcium looping process for carbon dioxide capture

This thesis presents a one-dimensional, semi-empirical dynamic model for the simulation and analysis of a calcium looping process for post-combustion CO2 capture. Reduction of greenhouse emissions from fossil fuel power production requires rapid actions including the development of efficient carbon capture and sequestration technologies. The development of new carbon capture technologies can be expedited by using modelling tools. Techno-economical evaluation of new capture processes can be done quickly and cost-effectively with computational models before building expensive pilot plants. Post-combustion calcium looping is a developing carbon capture process which utilizes fluidized bed technology with lime as a sorbent. The main objective of this work was to analyse the technological feasibility of the calcium looping process at different scales with a computational model. A one-dimensional dynamic model was applied to the calcium looping process, simulating the behaviour of the interconnected circulating fluidized bed reactors. The model incorporates fundamental mass and energy balance solvers to semi-empirical models describing solid behaviour in a circulating fluidized bed and chemical reactions occurring in the calcium loop. In addition, fluidized bed combustion, heat transfer and core-wall layer effects were modelled. The calcium looping model framework was successfully applied to a 30 kWth laboratory scale and a pilot scale unit 1.7 MWth and used to design a conceptual 250 MWth industrial scale unit. Valuable information was gathered from the behaviour of a small scale laboratory device. In addition, the interconnected behaviour of pilot plant reactors and the effect of solid fluidization on the thermal and carbon dioxide balances of the system were analysed. The scale-up study provided practical information on the thermal design of an industrial sized unit, selection of particle size and operability in different load scenarios.

Weed control in young coffee plantations through post emergence herbicide application onto total area

This study was carried out to investigate the efficiency of several herbicides under field conditions, by post-emergence application onto the entire area, their effect on the control of weeds in young coffee plantations and commercial coffee and bean intercropping system, as well as on both crops. Seedlings of Coffea arabica cv. Red Catuaí with four to six leaf pairs were transplanted to the field and treated according to conventional agronomic practices. A bean and coffee intercropping system was established by sowing three lines of beans in the coffee inter-rows. At the time the herbicides were sprayed, the coffee plants had six to ten leaf pairs; the bean plants, three leaflets; and the weeds were at an early development stage. Fluazifop-p-butyl and clethodim were selective for coffee plants and controlled only Brachiaria plantaginea and Digitaria horizontalis efficiently. Broad-leaved weeds (Amaranthus retroflexus, Bidens pilosa, Coronopus didymus, Emilia sonchifolia, Galinsoga parviflora, Ipomoea grandifolia, Lepidium virginicum, and Raphanus raphanistrum) were controlled with high efficiency by sole applications of fomesafen, flazasulfuron, and oxyfluorfen, except B. pilosa, C. didymus, and R. raphanistrum for oxyfluorfen. Sequential applications in seven-day intervals of fomesafen + fluazifop-p-butyl, or clethodim, and two commercial mixtures of fomesafen + fluazifop-p-butyl simultaneously controlled both types of weed. Cyperus rotundus was only controlled by flazasulfuron. Except for fluazifop-p-butyl and clethodim, all herbicide treatments caused only slight injuries on younger coffee leaves. However, further plant growth was not impaired and coffee plant height and stem diameter were therefore similar in the treatments, as evaluated four months later. Fomesafen, fluazifop-p-butyl, and clethodim, at sole or sequential application, and the commercial mixtures of fomesafen + fluazifop-p-butyl were also highly selective for bean crop; thus at doses recommended for bean crop, these herbicides may be applied to control weeds in coffee and bean intercropping systems by spraying the entire area.

Lujien painelaiteterästen hitsaus

Työn tavoitteena oli tutkia lujan nuorrutetun painelaiteteräksen P500QL2 hitsattavuutta ja koehitsausten avulla löytää optimaaliset hitsausparametrit ja lämmöntuonti teräksen hitsaukseen. Työn tavoitteena oli myös selvittää ja käsitellä kaikkien painelaiteterässtandardissa esitettyjen lujien painelaiteterästen hitsauksessa huomioon otettavia asioita. Työn teoriaosuudessa käsitellään lujien painelaiteterästen hitsauksessa huomioitavia erityispiirteitä, kuten lämmöntuontia, jäähtymisaikaa, esilämmitystä sekä hitsausaineiden valintaa. Lisäksi teoriaosuudessa käsitellään painelaitteiden valmistusta, painelaiteterässtandardiin kuuluvia lujia painelaiteteräksiä sekä keinoja lujien terästen hitsattavuuden arviointiin. Työn kokeellisessa osassa tutkittiin aineenvahvuudeltaan 50 mm paksun P500QL2-teräksen päittäisliitoksen mekaanisia ominaisuuksia eri lämmöntuonneilla hitsattuna. Kokeellisessa osassa tutkittiin myös myöstön poisjättämisen vaikutuksia liitoksen mekaanisiin ominaisuuksiin. Mekaanisia ominaisuuksia tutkittiin toteuttamalla koekappaleiden aineenkoetus menetelmäkoestandardin vaatimuksia soveltaen. Tutkimuksessa käytettyjä testausmenetelmiä olivat silmämääräinen tarkastus, magneettijauhetarkastus, ultraäänitarkastus, mikro- ja makrorakennetarkastelu, kovuuskokeet, vetokokeeet ja iskukokeet. Testauksessa saatujen tulosten avulla lujan painelaiteteräksen P500QL2 hitsaukseen laadittiin alustava hitsausohje. Hitsausliitosten testauksessa saatujen tulosten perusteella havaittiin hitsien lujuuden ja kovuuden laskevan lämmöntuonnin kasvaessa. Hitsausliitosten iskusitkeysominaisuudet olivat erinomaiset vielä suurellakin lämmöntuonnilla, mutta liitosten murtovenymäarvot laskivat lämmöntuonnin kasvaessa. Myöstön havaittiin parantavan hitsin mekaanisia ominaisuuksia huomattavasti. Tutkimuksen tulosten perusteella painelaiteteräs P500QL2 on hitsattavissa suurella lämmöntuonnilla ja suurella tuottavuudella liitoksen täyttäessä painelaitevalmistuksen edellyttämät vaatimukset.
