Luottamuksen rooli ja rakentuminen organisaation sisäisten yksiköiden välisessä yhteistyössä

Tämä tutkielma tarkastelee luottamuksen roolia organisaation sisäisessä yhteistyössä. Tavoitteena on tutkia niitä mekanismeja, joiden avulla luottamuksen ilmenemistä sisäisessä yhteistyössä voidaan vahvistaa. Toiseksi työ tarkastelee sitä, onko luottamus yhteystyössä henkilöityvää vai ei-henkilöityvää. Koska luottamusta on pääsääntöisesti tutkittu yrityskontekstissa, työn kolmantena tavoitteena on tarkastella sitä, vaikuttavatko kuntaorganisaation erityispiirteet luottamuksen ilmenemiseen yksiköiden välisessä yhteistyössä. Tämän laadullisen tutkimuksen teoreettinen osuus toteutettiin kirjallisuuskatsauksena. Tutkimuksen empiirisenä aineistona käytettiin narratiiveja, jotka olivat kuntaorganisaation keskijohdolta kerättyjä tarinoita. Aineiston analysointiin käytettiin sisällönanalyysin menetelmiä. Tutkimuksen tuloksena voidaan todeta, että luottamus on perusedellytys toimivalle yhteistyösuhteelle ja se rakentuu hyvin pitkälle käyttäytymisen ja kommunikoinnin kautta. Luottamus yhteistyössä ilmenee hyvin usein ei-henkilöityvänä luottamuksena, jolloin se kohdistuu siihen yksikköön, minkä kanssa yhteystyötä tehdään. Kuntaorganisaation erityispiirteillä ei ole merkittävää roolia luottamuksen ilmenemisessä yhteistyössä, vaikka virkamiehen virkavastuu onkin tarinoista nähtävissä.

Limnological research in the Iberian Peninsula: a ten-year survey of published literature.

Research on limnology in southern Europe had achieved a notable presence in the international arena before the onset of the current dramatic cuts in public investment in science. We assessed the limnological research published in peer-reviewed journals by Spanish and Portuguese (i.e., Iberian) researchers during the decade prior to the economic recession (2000 to 2009). The Thompson Reuters Web of Knowledge database was used to retrieve all publications on limnology authored by researchers affiliated with Spanish or Portuguese institutions independently of the geographical setting of the study. The publishing pattern was characterised in terms of authors, journals, and citation statistics. In addition, a thematic characterisation of the research was performed by a manual assignation of several categorical descriptors combined with a blind word count analysis. Iberian researchers produced an annual mean of 278 papers on limnology. Papers were published in journals that had impact factors ranging from 0.1 to 31.4, with a mean of 2.0. Based on citations, the impact of the Iberian limnological research was not due to a few highly cited papers but rather to a wide number of publications; each paper received a mean of 8 citations. The Iberian limnological research involved up to 5460 researchers, with a mean of 4.3 authors per paper. The research largely focused on fluvial systems, with 47 % of total publications (2778) devoted to these ecosystems. There was a dominant focus on local, within-system aspects of study sites and the research was mostly restricted to the Iberian Peninsula; larger spatial scales of analysis (i.e., landscape, regional, or global) tended to be overlooked. Iberian research addressed fundamental (75 %) rather than applied (17 %) or methodological (5 %) questions and was vastly dominated by observational approaches (75 %). Interestingly, Iberian limnological research increased its scientific productivity during the analysed decade at a higher rate than its international counterpart (increase of 119 %). Overall, Iberian research on limnology appeared to be in good health during the analysed decade. Certain areas have been more studied than others, which opens opportunities to develop new research.

A three dimensional study of heat transfer in a supercritical circulating fluidized bed combustor

From the boiler design point of view, it is imperative to know and understand the operation of the boiler. Since comprehensive measurement of a large furnace is impossible, the furnace can be modeled in order to study its behavior and phenomena. This requires the used model to be validated to correspond with the physical furnace behavior. In this thesis, a three dimensional furnace model is validated to match a bituminous coal utilizing, supercritical once-through circulating fluidized bed combustor based on measurement data. The validated model is used for analyzing the furnace heat transfer. Other heat transfer analysis methods are energy balance method based on tube surface temperature measurements and a method based on measured temperature difference between the tube crest and the fin. The latter method was developed in the thesis using Fluent-software. In the theory part, literature is reviewed and the fundamental aspects of circulating fluidized bed are discussed. These aspects are solid particle behavior in fluidization known as hydrodynamics, behavior of fuel and combustion and heat transfer. Fundamental aspects of modeling are also presented.

Métodos emergentes para aumentar a eficiência do ozônio no tratamento de águas contaminadas

Many industrial processes produce effluents with a wide variety of xenobiotic organic pollutants, which cannot be efficiently degraded by conventional biological treatments. Thus, the development of new technologies to eliminate these refractory compounds in water has become very imperative in order to assure the quality of this important resource. Ozonation is a very promising process for the treatment of wastewaters containing non-easily removable organic compounds. The present work aims at highlighting new methods of enhancing the efficiency of ozone towards the removal organic pollutants in aqueous solution. Special attention is given to catalytic ozonation processes contemplating homo- and heterogeneous catalysis, their activity and mechanisms. Recent results and future prospects about the application of these processes to real effluents are also evaluated.

Experimento utilizando grãos para explorar a calibração em análises químicas

The conventional curriculum of Analytical Chemistry undergraduate courses emphasizes the introduction of techniques, methods and procedures used for instrumental analysis. All these concepts must be integrated into a sound conceptual framework to allow students to make appropriate decisions. Method calibration is one of the most critical parameters that has to be grasped since most analytical techniques depend on it for quantitative analysis. The conceptual understanding of calibration is not trivial for undergraduate students. External calibration is widely discussed during instrumental analysis courses. However, the understanding of the limitations of external calibration to correct some systematic errors is not directly derived from laboratory examples. The conceptual understanding of other calibration methods (standard addition, matrix matching, and internal standard) is imperative. The aim of this work is to present a simple experiment using grains (beans, corn and chickpeas) to explore different types of calibration methods.

The destinal question of language

How can we think the destinal place of language in the essentially historical condition of our existence if such historicity cannot be understood on the basis of the labor of negativity alone? The attempt is made here to think language in a more originary manner, as non-negative finitude, that affirms what is outside dialectical-speculative closure, what is to come. The notion of 'destinal' itself is thus transformed. No longer being merely a categorical grasp of "entities presently given", language is an originary exposure to the event of arrival in its lightning flash. Destiny appears as that of the messianic arrival of the 'not yet' which is not a telos that the immanent movement of historical reason reaches by an irresistible force of the negative. This essay reads Schelling, Heidegger and Kierkegaard to think language as a "place" of exposure to the non-teleological destiny that may erupt even today, here and now, without any given conditionality.

On the institution of the moral subject: on the commander and the commanded in Nietzsche's discussion of law

The article discusses how Nietzsche understands the institution of law and morals in distinction to Kant and the Christian tradition. It argues that Nietzsche to a large extent is inspired by the paradigm-shift toward a evolutionary biological thinking introduced by several of his peers in the late 19th century, among else F. A. Lange, who sees this shift as a sobering scientific-materialistic alternative to Kant. In Nietzsche, the Kantian moral imperative is replaced with a notion of a morality emerging thanks to historical, or pre-historical, civilizational processes, imposed on a feebleminded human without any inherent rational dispositions to obey Law. It is also a process, which rather than universalizing the human, splits it in a duality where one part obeys old immediate self-interests and another part obeys new 'commands,' having been shouted 'into the ear' by a so-called 'commander.' The compliance with law takes two radically different forms in Nietzsche: servile and mediocre individuals need to be exposed to discipline and punishment in order to adopt Law; while so-called 'sovereign' individuals are able to impose law upon themselves. The figure of the 'sovereign' has consequently been an issue for vigorous debate in especially the Anglo-Saxon tradition of Nietzsche research, since his apparent 'respect for law' and 'sense of duty' reiterate typical Kantian qualities. Relating to these discussions, I suggest that Nietzsche's 'sovereign' (in one context) is identical his 'commander' (in other contexts). When the 'sovereign' as such imposes law upon himself and others, his act is conventional and arbitrary (like language in Saussure), and is rather irrational than rational as in Kant. His will is not a good will, nor a rational will with a vision of human autonomy. His command of himself and others is a performative, thus without truth-value (like illocutionary speech-acts in Austin and Searle).

Applications of graph transformation in tools for domain-specific modeling languages

The use of domain-specific languages (DSLs) has been proposed as an approach to cost-e ectively develop families of software systems in a restricted application domain. Domain-specific languages in combination with the accumulated knowledge and experience of previous implementations, can in turn be used to generate new applications with unique sets of requirements. For this reason, DSLs are considered to be an important approach for software reuse. However, the toolset supporting a particular domain-specific language is also domain-specific and is per definition not reusable. Therefore, creating and maintaining a DSL requires additional resources that could be even larger than the savings associated with using them. As a solution, di erent tool frameworks have been proposed to simplify and reduce the cost of developments of DSLs. Developers of tool support for DSLs need to instantiate, customize or configure the framework for a particular DSL. There are di erent approaches for this. An approach is to use an application programming interface (API) and to extend the basic framework using an imperative programming language. An example of a tools which is based on this approach is Eclipse GEF. Another approach is to configure the framework using declarative languages that are independent of the underlying framework implementation. We believe this second approach can bring important benefits as this brings focus to specifying what should the tool be like instead of writing a program specifying how the tool achieves this functionality. In this thesis we explore this second approach. We use graph transformation as the basic approach to customize a domain-specific modeling (DSM) tool framework. The contributions of this thesis includes a comparison of di erent approaches for defining, representing and interchanging software modeling languages and models and a tool architecture for an open domain-specific modeling framework that e ciently integrates several model transformation components and visual editors. We also present several specific algorithms and tool components for DSM framework. These include an approach for graph query based on region operators and the star operator and an approach for reconciling models and diagrams after executing model transformation programs. We exemplify our approach with two case studies MICAS and EFCO. In these studies we show how our experimental modeling tool framework has been used to define tool environments for domain-specific languages.

Military crisis management in the next decade (2020-2030) : inducing consent or relying on compliance?

The most outstanding conceptual challenge of modern crisis management is the principle of consent. It is not a problem only at the operational level - it challenges the entire decision-making structures of crisis management operations. In post-cold war times and especially in the 21st century, there has been a transition from peacekeeping with limited size and scope towards large and complex peace operations. This shift has presented peace operations with a dilemma. How to balance between maintaining consent for peace operations, whilst being able to use military force to coerce those attempting to wreck peace processes? To address such a dilemma, this research aims to promote understanding, on what can be achieved by military crisis management operations (peace support operations) in the next decade. The research concentrates on the focal research question: Should military components induce consent or rely on the compliance of conflicting parties in crisis management operations of the next decade (2020 – 2030)? The focus is on military – political strategic level considerations, and especially on the time before political decisions to commit to a crisis management operation. This study does not focus on which actor or organisation should intervene. The framework of this thesis derives from the so called ‘peacebuilding space’, the scope of peace operations and spoiler theory. Feasibility of both peace enforcement and peacekeeping in countering future risk conditions are analysed in this framework. This future-orientated qualitative research uses the Delphi-method with a panel of national and international experts. Citation analysis supports identification of relevant reference material, which consists of contemporary literature, the Delphi-questionnaires and interviews. The research process followed three main stages. In the first stage, plausible future scenarios and risk conditions were identified with the Delphi-panel. In the second stage, operating environments for peace support operations were described and consequent hypotheses formulated. In the third stage, these hypotheses were tested on the Delphi-panel. The Delphi-panel is sufficiently wide and diverse to produce plausible yet different insights. The research design utilised specifically military crisis management and peace operations theories. This produced various and relevant normative considerations. Therefore, one may argue that this research; which is based on accepted contemporary theory, hypotheses derived thereof and utilising an expert panel, contributes to the realm of peace support operations. This research finds that some degree of peace enforcement will be feasible and necessary in at least the following risk conditions: failed governance; potential spillover of ethnic, religious, ideological conflict; vulnerability of strategic chokepoints and infrastructures in ungoverned spaces; as well as in territorial and extra-territorial border disputes. In addition, some form of peace enforcement is probably necessary in risk conditions pertaining to: extremism of marginalised groups; potential disputes over previously uninhabited and resource-rich territories; and interstate rivalry. Furthermore, this research finds that peacekeeping measures will be feasible and necessary in at least risk conditions pertaining to: potential spillover of ethnic, religious, ideological conflict; uncontrolled migration; consequences from environmental catastrophes or changes; territorial and extra-territorial border disputes; and potential disputes over previously uninhabited and resource-rich territories. These findings are all subject to both generic and case specific preconditions that must exist for a peace support operation. Some deductions could be derived from the research findings. Although some risk conditions may appear illogical, understanding the underlying logic of a conflict is fundamental to understanding transition in crisis management. Practitioners of crisis management should possess cognizance of such transition. They must understand how transition should occur from threat to safety, from conflict to stability – and so forth. Understanding transition is imperative for managing the dynamic evolution of preconditions, which begins at the outset of a peace support operation. Furthermore, it is pertinent that spoilers are defined from a peace process point of view. If spoilers are defined otherwise, it changes the nature of an operation towards war, where the logic is breaking the will of an enemy - and surrender. In peace support operations, the logic is different: actions towards spoilers are intended to cause transition towards consent - not defeat. Notwithstanding future developments, history continues to provide strategic education. However, the distinction is that the risk conditions occur in novel futures. Hence, lessons learned from the past should be fitted to the case at hand. This research shows compelling evidence that swaying between intervention optimism and pessimism is not substantiated. Both peace enforcement and peacekeeping are sine qua non for successful military crisis management in the next decade.

Leadership in the mobile smartphone market

The mobile telecommunications industry has been going through an enormous revolution, especially after mid-1990 when smartphones were introduced to the market. As a consequence, the smartphone market’s dynamism is requesting companies to operate differently in the way they do business. After a long period occupying the leader position in the smartphones manufacturers’ rank, Nokia was outperformed by Apple and Samsung during 2011 and since then has been on the third place. Nevertheless, Nokia is battling for regaining the leadership in such a competitive and high-velocity growing market and that is what this research is about. This research covers the competitive and strategic forces that shape dynamic industries whereas the main purpose is to elucidate the main factors that contribute to a company’s above-average performance and ultimately determine its leadership in the mobile smartphone market. Therefore, this exploratory qualitative research was conducted as a desk research, which utilized various secondary sources of data in the knowledge area of strategic management such as theories about competitive advantages and dynamic capabilities of firms, innovation, and strategy. This research is enriched with a case study about Nokia: how the company has been organizing its corporate structure to support the strategies and hence how it has been competing in the smartphone market is analyzed, taking into account many contemporary data sources, including market analysts’ and business experts’ opinions. As a result of the classic literature exploration and the case study assay, a framework for deeper analysis of the competitiveness of firms in dynamic markets was developed. The conclusion that emerged from this research is that the success of a firm results from the interplay of various factors. To regain the leader position in the mobile smartphone market is a challenging task that requires Nokia to reinvent its core strategy for taking charge of the smartphones’ industry transformation through for example the adoption of the open innovation concept. It is imperative that Nokia designs and implement a breakthrough strategy as well as embraces the uncertainty of the smartphone market competition as an opportunity for discontinuous innovation development with the ultimate goal of recovering the leadership.

Reconstrução da parede torácica nos defeitos adquiridos

Acquired chest wall defects present a challenging problem for thoracic surgeons. Many of such defects can be repaired with the use of local and regional musculocutaneous flaps, but larger defects compromising skeletal structure require increasingly sophisticated reconstructive techniques. The following discussion will review the options for repair acquired chest wall defects based in literature. The authors searched the Pubmed (www.pubmed.com) and found citations from January 1996 to February 2008. By reading the titles and the abstracts most of the citations were discharged because they focused in congenital chest wall defects or were cases report. However, many papers were found describing the outcome of large series of patients with acquired chest wall deformities. A review of recent literature shows that the repair of chest wall defects with soft tissues, if possible, remains the treatment of choice. Large chest wall defects require skeletal reconstruction to prevent paradoxical respiration. The selection of the most appropriate flap is primary dictated by the location and the size of the defect. It is important to transfer tissue with good vitality, so understanding the vascular supply is imperative. Autogenous grafts have been used in the past for skeletal reconstruction but a combination of synthetic materials with musculocutaneous flaps has been used lately. Based in the literature, the use of prosthetic material in chest wall reconstruction does not significantly increases the risk of wound infection.

System to outline the graduatestudents

Objective: to evaluate the system to outline the graduate students from the Post-Graduate Programs of CAPES Medicine III area. Method: it was analyzed the book of indicators and the Document of Area of the Post-Graduate Programs of Surgery, also checking the literature about this issue. Results: there was a paucity of data from most of the programs, as regards to the methods for evaluation of graduate students. The current system lacks a standard and an institutional support to outline the graduate students. In the public system there is a concentration of postgraduate students in Medicine; however, they represent a small part of those Brazilians students who finished their graduation courses in Medicine. In the current context, the quest for the post graduate courses and consequently for a research field or even a teaching career, has been replaced by the private sector jobs and the labor market, both in non-academic assistance activities. Conclusion: it is imperative to establish not only science and technology innovation policies but also educational and health policies acting harmoniously and stimulating the qualification and the teaching career, improving the post-graduate courses. It is necessary to develop a single form under the institutional guidance of CAPES with the conception of a National Program for Graduate Student in order to consolidate guidelines to mapping the graduate students of post-graduate programs in surgery, in our country.

Relationship between anxiety and overactive bladder syndrome in older women

PURPOSE: The objective of this study was to investigate the relationship between overactive bladder syndrome and anxiety in older women.METHODS: Of the 198 older women who were invited, 29 were excluded and 166 were then divided into two groups according to the Advanced Questionnaire of Overactive Bladder (OAB-V8): one group with overactive bladder symptoms (OAB-V8≥8) and the other without the symptoms of an overactive bladder (OAB-V8<8). The purpose was to conduct a frequency analysis and to investigate the relation of the social demographic data and anxiety in the two groups. The Beck Anxiety Inventory (BAI) was used to evaluate the level of anxiety. The Kolmogorov-Smirnov test was used to determine the distribution of the data. The differences between the two groups for the continuous variables were analyzed by the Mann-Whitney U test, the differences for the categorical variables were analyzed by the Chi-Square test and the association between the continuous variables was analyzed by the Spearman Correlation test. The tests were two-tailed with a confidence level of 5%.RESULTS: Overall, the frequency of an overactive bladder was present in 117 (70.5%) of the participants. The body mass index (BMI) of the group with overactive bladder symptoms was significantly higher than the BMI of those without these symptoms (p=0.001). A higher prevalence of mild, moderate and severe anxiety was observed among older women with overactive bladder symptoms. In addition, the overactive bladder symptoms group presented a positive low correlation with anxiety symptoms (r=0.345) and with BMI (r=0.281). There was a small correlation between BMI and anxiety symptoms (r=0.164).CONCLUSIONS: Overactive bladder syndrome was prevalent among older women and the existence of these symptoms was linked to the presence of mild, moderate and/or severe anxiety symptoms.

Loss of PTEN expression and AKT activation in HER2-positive breast carcinomas

PURPOSE: To examine the expression of AKT and PTEN in a series of HER2-positive primary invasive breast tumors using immunohistochemistry, and to associate these expression profiles with classic pathologic features such as tumor grade, hormone receptor expression, lymphatic vascular invasion, and proliferation.METHODS: A total of 104 HER2-positive breast carcinoma specimens were prepared in tissue microarrays blocks for immunohistochemical detection of PTEN and phosphorylated AKT (pAKT). Original histologic sections were reviewed to assess pathological features, including HER2 status and Ki-67 index values. The associations between categorical and numeric variables were identified using Pearson's chi-square test and the Mann-Whitney, respectively.RESULTS: Co-expression of pAKT and PTEN was presented in 59 (56.7%) cases. Reduced levels of PTEN expression were detected in 20 (19.2%) cases, and these 20 tumors had a lower Ki-67 index value. In contrast, tumors positive for pAKT expression [71 (68.3%)] were associated with a higher Ki-67 index value.CONCLUSION: A role for AKT in the proliferation of HER2-positive breast cancers was confirmed. However, immunohistochemical detection of PTEN expression did not correlate with an inhibition of cellular proliferation or control of AKT phosphorylation, suggesting other pathways in these mechanisms of control.

Increased oxidative stress markers may be a promising indicator of risk for primary ovarian insufficiency: a cross-sectional case control study

PURPOSE: The aim of this study was to evaluate serum levels of inducible nitric oxide synthase (INOS), myeloperoxidase (MPO), total antioxidant status (TAS), and total oxidative status (TOS) in women with primary ovarian insufficiency (POI) and to compare them with healthy fertile women. We also examined the possible risk factors associated with POI.METHODS: This cross-sectional case control study was conducted in Zekai Tahir Burak Women's Health Education and Research Hospital. The study population consisted of 44 women with POI (study group) and 36 healthy fertile women (control group). In all patients, serum levels of INOS, MPO, TAS, and TOS were determined. INOS and MPO levels were measured by enzyme-linked immunosorbent assay whereas colorimetric method was used for evaluating TAS and TOS levels. Age, body mass index (BMI), obstetric history, smoking status, family history, comorbidities, sonographic findings, complete blood count values, C-reactive protein and baseline hormone levels were also analyzed. Student's t-test or Mann-Whitney U test was used to compare continuous variables between the groups; categorical data were evaluated by using Pearson χ2 or Fisher exact test, when appropriate. Binary logistic regression method was used to identify risk factors for POI.RESULTS: We found significantly elevated levels of INOS (234.1±749.5 versus133.8±143.0; p=0.005), MPO (3,438.7±1,228.6 versus 2,481.9±1,230.1; p=0.001), and TOS (4.3±1.4 versus 3.6±1.4; p=0.02) in the sera of the study group when compared to the BMI-age matched control group. However, difference in serum levels of TAS were not significant between the 2 groups (1.7±0.2 versus 1.6±0.2; p=0.15). Logistic regression method demonstrated that BMI <25 kg/m2, nulliparity, family history of POI, smoking, and elevated serum levels of INOS, MPO, and TOS were independent risk factors for POI.CONCLUSION: We found an increase in INOS, MPO, and TOS in women with POI. These serum markers may be promising in early diagnosis of POI. Further large-scale studies are required to determine whether oxidative stress markers have a role in diagnosing POI.
