Magnetic, thermal and spectral properties of Ni(II) 2,3- , 3,5- and 2,6-dimethoxybenzoates

Complexes of Ni(II) 2,3-, 3,5- and 2,6-dimethoxybenzoates have been synthesized, their physico-chemical properties have been compared and the influence of the position of -OCH3 substituent on their properties investigated. The analysed compounds are crystalline, hydrated salts with green colour. The carboxylate ions show a bidentate chelating or bridging coordination modes. The thermal stabilities of Ni(II) dimethoxybenzoates were investigated in air in the range of 293-1173 K. The complexes decompose in three steps, yelding the NiO as the final product of decomposition. Their solubilities in water at 293 K are in the order of 10-2-10-4 mol×dm-3. The magnetic susceptibilities for the analysed dimethoxybenzoates of Ni(II) were measured over the range of 76-303 K and the magnetic moments were calculated. The results reveal that the complexes are the high-spin ones and the ligands form the weak electrostatic field in the octahedral coordination sphere of the central Ni(II) ion. The various position -OCH3 groups in benzene ring cause the different steric, mesomeric and inductive effects on the electron density in benzene ring.

Nursing Ethics Education in Finland from the Perspective of Codes of Ethics

The purpose of this study was to analyze nursing ethics education from the perspective of nurses’ codes of ethics in the basic nursing education programmes in polytechnics in Finland with the following research questions: What is known about nurses’ codes in practice and education, what contents of the codes are taught, what teaching and evaluation methods are used, which demographic variables are associated with the teaching, what is nurse educators’ adequacy of knowledge to teach the codes and nursing students’ knowledge of and ability to apply the codes, and what are participants’ opinions of the need and applicability of the codes, and their importance in nursing ethics education. The aim of the study was to identify strengths and possible problem areas in teaching of the codes and nursing ethics in general. The knowledge gained from this study can be used for developing nursing ethics curricula and teaching of ethics in theory and practice. The data collection was targeted to all polytechnics in Finland providing basic nursing education (i.e. Bachelor of Health Care). The target groups were all nurse educators teaching ethics and all graduating nursing students in the academic year of 2006. A total of 183 educators and 214 students from 24 polytechnics participated. The data was collected using a structured questionnaire with four open-ended questions, designed for this study. The data was analysed by SPSS (14.0) and the open-ended questions by inductive content analysis. Descriptive statistics were used to summarize the data. Inferential statistics were used to estimate the differences between the participant groups. The reliability of the questionnaire was estimated with Cronbach’s coefficient alpha. The literature review revealed that empirical research on the codes was scarce, and minimal in the area of education. Teaching of nurses’ codes themselves and the embedded ethical concepts was extensive, teaching of the functions of the codes and related laws and agreements was moderate, but teaching of the codes of other health care professions was modest. Issues related to the nurse-patient relationship were emphasised. Wider social dimensions of the codes were less emphasized. Educators’ and students’ descriptions of teaching emphasized mainly the same teaching contents, but there were statistically significant differences between the groups in that educators assessed their teaching to be more extensive than what students had perceived it had been. T he use of teaching and evaluation methods was rather narrow and conventional. However, educators’ and students’ descriptions of the used methods differed statistically significantly. Students’ knowledge of the codes and their ability to apply them in practice was assessed as mediocre by educators and by students themselves. Most educators assessed their own knowledge of the codes as adequate to teach the codes, as did most of the students. Educators who regarded their knowledge as adequate taught the codes more extensively than those who assessed their knowledge as less adequate. Also students who assessed their educators’ knowledge as adequate perceived the teaching of the codes to be more extensive. Otherwise educators’ and students’ demographic variables had little association with their descriptions of the teaching. According to the participants, nurses need their own codes, and they are also regarded as applicable in practice. The codes are an important element in nursing ethics education, but their teaching needs development. Further research should focus on the organization of ethics teaching in the curricula, the teaching process, and on the evaluation of the effectiveness of ethics education and on educators’ competence. Also the meaning and functions of the codes at all levels of nursing deserve attention. More versatile use of research methods would be beneficial in gaining new knowledge.

Clinical reasoning of medical students in a public university in Brazil

The aim of this research was to understand the reasoning developed by medical students in a public university in Brazil. This research on education included semi-structured interviews and film recordings of interns discussing 10 clinical cases. A sample of 16 interns analyzed cases presented on a notebook computer with a webcam. They were instructed to verbalize all their thoughts on the procedures they would use. The film recordings and transcripts of the interviews were analyzed. Quantitative data was evaluated using Yates' chi-squared test and speech analysis was used to evaluate the transcripts. The theme worked on in the practice of reasoning was: the student's perceptions of their clinical practice. Of the 160 diagnoses, 57% were done with analytical reasoning and 43% with non-analytical reasoning. The hypothetical deductive method was employed by 31% of the interns and the inductive method was employed by 69%. The diagnostic accuracy was 81% correct for easy cases and 85% correct for difficult cases. We observed two empirical categories: the cognitive universe of the student and the patient's context.

General terms and rigidity: another solution to the trivialization problem

In this paper I am concerned with the problem of applying the notion of rigidity to general terms. In Naming and Necessity, Kripke has clearly suggested that we should include some general terms among the rigid ones, namely, those common nouns semantically correlated with natural substances, species and phenomena, in general, natural kinds -'water', 'tiger', 'heat'- and some adjectives -'red', 'hot', 'loud'. However, the notion of rigidity has been defined for singular terms; after all, the notion that Kripke has provided us with is the notion of a rigid designator. But general terms do not designate single individuals: rather, they apply to many of them. In sum, the original concept of rigidity cannot be straightforwardly applied to general terms: it has to be somehow redefined in order to make it cover them. As is known, two main positions have been put forward to accomplish that task: the identity of designation conception, according to which a rigid general term is one that designates the same property or kind in all possible worlds, and the essentialist conception, which conceives of a rigid general term as an essentialist one, namely, a term that expresses an essential property of an object. My purpose in the present paper is to defend a particular version of the identity of designation conception: on the proposed approach, a rigid general term will be one that expresses the same property in all possible worlds and names the property it expresses. In my opinion, the position can be established on the basis of an inference to the best explanation of our intuitive interpretation and evaluation, relative to counterfactual circumstances, of statements containing different kinds of general terms, which is strictly analogous to our intuitive interpretation and evaluation, relative to such circumstances, of statements containing different kinds of singular ones. I will argue that it is possible to offer a new solution to the trivialization problem that is thought to threaten all versions of the identity of designation conception of rigidity. Finally, I will also sketch a solution to the so-called 'over-generalization and under-generalization problems', both closely related to the above-mentioned one.

MCMC Analysis for Optimization of Stochastic Models

In any decision making under uncertainties, the goal is mostly to minimize the expected cost. The minimization of cost under uncertainties is usually done by optimization. For simple models, the optimization can easily be done using deterministic methods.However, many models practically contain some complex and varying parameters that can not easily be taken into account using usual deterministic methods of optimization. Thus, it is very important to look for other methods that can be used to get insight into such models. MCMC method is one of the practical methods that can be used for optimization of stochastic models under uncertainty. This method is based on simulation that provides a general methodology which can be applied in nonlinear and non-Gaussian state models. MCMC method is very important for practical applications because it is a uni ed estimation procedure which simultaneously estimates both parameters and state variables. MCMC computes the distribution of the state variables and parameters of the given data measurements. MCMC method is faster in terms of computing time when compared to other optimization methods. This thesis discusses the use of Markov chain Monte Carlo (MCMC) methods for optimization of Stochastic models under uncertainties .The thesis begins with a short discussion about Bayesian Inference, MCMC and Stochastic optimization methods. Then an example is given of how MCMC can be applied for maximizing production at a minimum cost in a chemical reaction process. It is observed that this method performs better in optimizing the given cost function with a very high certainty.

Viestitaktiikan kehittyminen yhtymän viestijärjestelmän käyttöönoton jälkeen

Tutkimus käynnistyi Maanpuolustuskorkeakoulun taktiikan laitoksen esittäessä aihepiiriä tutkittavaksi. Tutkimuksen tavoitteena on ollut lisätä tietämystä viestitaktiikan kehittymisestä yhtymän viestijärjestelmän käyttöönoton jälkeen 1980 – 2000-luvuilla osana operatiivistaktisten toimintaperiaatteiden ja -tapojen kehittymistä. Tutkimuksella on pyritty syventämään tietämystä taktisten periaatteiden muutoksista viestitaktiikan näkökulmasta. Tutkimuksessa tarkasteltiin maavoimien YVI-järjestelmillä varustettujen yhtymien viestitaktiikkaa sekä niissä tapahtuneita muutoksia. Muutoksia tarkasteltaessa tutkimuksessa keskityttiin käsitykseen viestitaktiikasta, viestitaktisiin periaatteisiin sekä viestipäällikköön ja hänen toimintakenttäänsä. Viestitaktisia periaatteita ja niissä tapahtuneita muutoksia vertailtiin myös yleisiin taktisiin periaatteisiin ja niiden painotuksissa tapahtuneisiin muutoksiin. Tutkimus on luonteeltaan kvalitatiivinen. Tutkimusongelmia lähestyttiin fenomenografisella tutkimusotteella, jossa tavoitteena on kuvailla, analysoida ja ymmärtää erilaisia käsityksiä ilmiöistä sekä käsitysten keskinäisistä suhteista. Lähdeaineiston muodostivat 18 viestitaktiikan asiantuntijan kokemusperäiset käsitykset viestitaktiikasta ja sen kehittymisestä YVIjärjestelmien käyttöönoton jälkeen. Käsityksistä muodostettiin merkitys- ja kuvauskategorioiden sekä tutkijan esiymmärryksen pohjalta induktiivisen päättelyn avulla tutkimuksen varsinaiset johtopäätökset. Tutkimushenkilöiden käsitysten sekä taktiikan ja viestitaktiikan aikaisempien määritelmien perusteella johtopäätöksenä määritettiin, että viestitaktiikka on tehtävän toteuttamiseen käytettävissä olevan viestillisen kapasiteetin optimaalista suunnittelua, soveltamista ja käyttöä viestivoimana haluttujen päämäärien saavuttamiseksi ja viestitaisteluiden voittamiseksi. Viestitaktikointi edellyttää viestitaisteluun liittyvien keinojen tuntemista sekä taitoa soveltaa niitä käytännössä. Tutkimustulosten perusteella keskeisiksi viestitaktisiksi periaatteiksi tärkeysjärjestyksessä muodostuivat - päämäärän ja tehtävän selkeys - varautuminen odottamattomiin tilanteen vaihteluihin - yksinkertaisuus - aktiivisuus ja oma-aloitteisuus. Keskeisiksi merkitystään lisänneiksi viestitaktisiksi periaatteiksi muodostuivat - voimien vaikutuksen keskittäminen - joukkojen ja voimien jakaminen (reservi) - varautuminen odottamattomiin tilanteen vaihteluihin - salaaminen ja harhauttaminen - turvallisuus. Selkeimpänä viestipäällikön tehtävien muutoksena pidettiin siirtymistä yksityiskohtaisesta viestiyhteyksien suunnittelijasta kokonaisvaltaiseksi yhtymän viestitoiminnan johtajaksi. Tutkimustulosten ja aikaisempien määritelmien perusteella johtopäätöksenä määritettiin, että viestipäällikkö johtaa yhtymän viestitoimintaa komentajan antamien vaatimusten mukaisesti ja vastaa yhtymän johtoryhmän jäsenenä viestitaktisista ratkaisuista haluttujen päämäärien saavuttamiseksi ja viestitaisteluiden voittamiseksi. Viestipäälliköltä edellytetään viestitaisteluun liittyvien keinojen tuntemista sekä taitoa soveltaa niitä käytännössä. Tutkimuksen mukaan yhtymän viestitaktiikkaan merkittävimmin vaikuttaneita tekijöitä olivat yhtymän viestijärjestelmien käyttöönotto, uusien esikunta- ja viestiyksiköiden kehittäminen, kiinteän viestiverkon ja johtamisjärjestelmäalan merkityksen kasvaminen, käytettävien tekniikoiden kehittyminen sekä joukkojen ja johtoportaiden tiedonsiirtotarpeiden kasvaminen. Viestitaktiikan osalta voidaan todeta deterministisen näkemyksen taistelusta ja taistelutilasta muuttuneen yleisten taktisten periaatteiden muutosten mukaisesti aikaisempaa monimuotoisempaan ja rohkeampaan, voluntaarisempaan, suuntaan.

Preventive diagnosis of dairy cow lameness

This research aimed to develop a Fuzzy inference based on expert system to help preventing lameness in dairy cattle. Hoof length, nutritional parameters and floor material properties (roughness) were used to build the Fuzzy inference system. The expert system architecture was defined using Unified Modelling Language (UML). Data were collected in a commercial dairy herd using two different subgroups (H1 and H2), in order to validate the Fuzzy inference functions. The numbers of True Positive (TP), False Positive (FP), True Negative (TN), and False Negative (FN) responses were used to build the classifier system up, after an established gold standard comparison. A Lesion Incidence Possibility (LIP) developed function indicates the chances of a cow becoming lame. The obtained lameness percentage in H1 and H2 was 8.40% and 1.77%, respectively. The system estimated a Lesion Incidence Possibility (LIP) of 5.00% and 2.00% in H1 and H2, respectively. The system simulation presented 3.40% difference from real cattle lameness data for H1, while for H2, it was 0.23%; indicating the system efficiency in decision-making.

Fuzzy modeling of broiler performance, raised from 1 to 21 days, subject to heat stress

ABSTRACT Given the need to obtain systems to better control broiler production environment, we performed an experiment with broilers from 1 to 21 days, which were submitted to different intensities and air temperature durations in conditioned wind tunnels and the results were used for validation of afuzzy model. The model was developed using as input variables: duration of heat stress (days), dry bulb air temperature (°C) and as output variable: feed intake (g) weight gain (g) and feed conversion (g.g-1). The inference method used was Mamdani, 20 rules have been prepared and the defuzzification technique used was the Center of Gravity. A satisfactory efficiency in determining productive responses is evidenced in the results obtained in the model simulation, when compared with the experimental data, where R2 values ​​calculated for feed intake, weight gain and feed conversion were 0.998, 0.981 and 0.980, respectively.

Integration in project business : mechanisms for integrating customers and the project network during the life-cycle of industrial projects

This thesis focuses on integration in project business, i.e. how projectbased companies organize their product and process structures when they deliver industrial solutions to their customers. The customers that invest in these solutions run their businesses in different geographical, political and economical environments, which should be acknowledged by the supplier when providing solutions comprising of larger and more complex scopes than previously supplied to these customers. This means that the suppliers are increasing their supply range by taking over some of the activities in the value chain that have traditionally been handled by the customer. In order to be able to provide the functioning solutions, including more engineering hours, technical equipment and a wider project network, a change is needed in the mindset in order to be able to carry out and take the required responsibility that these new approaches bring. For the supplier it is important to be able to integrate technical products, systems and services, but the supplier also needs to have the capabilities to integrate the cross-functional organizations and departments in the project network, the knowledge and information between and within these organizations and departments, along with inputs from the customer into the product and process structures during the lifecycle of the project under development. Hence, the main objective of this thesis is to explore the challenges of integration that industrial projects meet, and based on that, to suggest a concept of how to manage integration in project business by making use of integration mechanisms. Integration is considered the essential process for accomplishing an industrial project, whereas the accomplishment of the industrial project is considered to be the result of the integration. The thesis consists of an extended summary and four papers, that are based on three studies in which integration mechanisms for value creation in industrial project networks and the management of integration in project business have been explored. The research is based on an inductive approach where in particular the design, commissioning and operations functions of industrial projects have been studied, addressing entire project life-cycles. The studies have been conducted in the shipbuilding and power generation industries where the scopes of supply consist of stand-alone equipment, equipment and engineering, and turnkey solutions. These industrial solutions include demanding efforts in engineering and organization. Addressing the calls for more studies on the evolving value chains of integrated solutions, mechanisms for inter- and intra-organizational integration and subsequent value creation in project networks have been explored. The research results in thirteen integration mechanisms and a typology for integration is proposed. Managing integration consists of integrating the project network (the supplier and the sub-suppliers) and the customer (the customer’s business purpose, operations environment and the end-user) into the project by making use of integration mechanisms. The findings bring new insight into research on industrial project business by proposing integration of technology and engineering related elements with elements related to customer oriented business performance in contemporary project environments. Thirteen mechanisms for combining products and the processes needed to deliver projects are described and categorized according to the impact that they have on the management of knowledge and information. These mechanisms directly relate to the performance of the supplier, and consequently to the functioning of the solution that the project provides. This thesis offers ways to promote integration of knowledge and information during the lifecycle of industrial projects, enhancing the development towards innovative solutions in project business.

Kirurgisten potilasohjeiden laatu ja valmius tukea voimavaraistavaa potilasohjausta sekä infektioiden torjuntaan liittyvä sisältö

Hoitotyössä infektioiden torjunnan painopistealueena on ollut lisätä potilaiden osallistuvuutta voimavaraistavalla potilasohjauksella. Potilasohjauksen apuna käytetään usein kirjallisia potilasohjeita, joiden rakenne ja laatu tulee olla hyvä. Lisäksi potilasohjeiden tulee omata valmiuksia tukea voimavaraistavaa potilasohjausta. Kirjalliset potilasohjeet ovat hyvä potilasohjauksen keino, mutta systemaattinen tieto potilasohjeiden laadusta, valmiuksista tukea voimavaraistavaa potilasohjausta sekä infektioiden torjunnan sisällöstä puuttuu. Tutkimuksen tarkoituksena oli analysoida Suomen yliopistosairaaloiden kirurgisten potilasohjeiden infektioiden torjuntaan liittyvää sisältöä. Lisäksi oltiin kiinnostuneita potilasohjeiden laadusta hyvien kirjallisten potilasohjeiden ominaispiirteiden toteutumisessa sekä potilasohjeiden valmiuksista tukea voimavaraistavaa potilasohjausta. Tutkimuksen aineistona oli viiden yliopistosairaalan kirurgisille aikuispotilaille tarkoitetut potilasohjeet (N = 237). Organisaatioittain joka viides potilasohje (n = 50) analysoitiin potilasohjeiden laadun osalta sisällönerittelyllä ja aikaisemmin kehitetyn mittarin avulla (Salanterä ym. 2004). Deduktiivisella sisällönanalyysillä analysoitiin potilasohjeiden valmiuksia tukea voimavaraistavaa potilasohjausta, jonka ulottuvuuksien esiintyvyyden arviointiasteikko oli kehitetty tätä tutkimusta varten. Induktiivisella sisällönerittelyllä analysoitiin infektioiden torjuntaan liittyvä sisältö. Potilasohjeiden laadussa oli paljon vaihtelua, ja vain 36 % (n = 18) potilasohjeista oli julkaistu viimeisen kolmen vuoden (2010–2012) aikana. Potilasohjeet olivat ulkoasultaan selkeitä ja johdonmukaisia, jolloin kirjallisten potilasohjeiden ominaisuuksista parhaiten toteutuivat ulkoasun sekä kielen ja rakenteen ominaisuudet. Potilasohjeet kuvasivat toimenpidettä ja siitä selviytymistä, antaen parhaiten valmiuksia tukea toiminnallista ja bio-fysiologista selviytymistä potilasohjauksella. Infektioiden torjuntaan liittyvä sisältö oli pääasiassa esitetty epäsuorasti toisen asian kautta. Infektioiden syntyyn tai torjuntaan ei viitattu, vaan asiaa tarkasteltiin muusta näkökulmasta esimerkiksi ylipainon ja ihon kunnon osalta. Yleisin infektioiden torjuntaan liittyvä sisältö koski käsihygieniaa, vaikka sen toteuttamista ei opastettu tai ohjeistettu. Tutkimus tarjoaa lähtökohdan kehittää potilasohjeiden infektioiden torjuntaan liittyvää sisältöä sekä potilaan osallistuvuuden lisäämistä. Erityisesti tulisi kehittää potilaan osallistuvuuden tukemista voimavaraistavalla potilasohjauksella. Jatkotutkimuksena tulisi kartoittaa potilaiden tarpeet infektioiden torjunnan sisällöstä sekä kehittää kansallinen ohjeistus potilasohjeiden infektioon torjuntaan liittyvästä sisällöstä ja rakenteesta.

Marketers’ perception of the implementation of social media marketing: Evidence from large Finnish companies’ marketing campaigns

Social media is a multidimensional marketing and communications channel which can support and enhance a business’ reputation, sales and even longevity. Social media as a business tool encourages an interaction between customers and companies which gives opportunities for a company to better understand their customers, to target them more effectively and to collaborate and create dialogues with them which is not possible through traditional media channels. The aim of a social media strategy is to increase brand awareness, image, loyalty and recognition. The peer networks that social media creates allows a company to disseminate information through loyal customers to new and prospective customers to ultimately increase reach. The purpose of the study is to understand the marketer’s perspective of social media marketing use and how it is currently utilized in marketing and communications activities in Finland. Three companies were interviewed covering fourteen different implementations of social media marketing campaigns. These were then analysed to ascertain the utilization methods and experience gained on recent campaigns in the Finnish market The utilization of social media marketing was analysed using the methods of thematic analysis and inductive and abductive reasoning. Elements and themes were drawn out of the separate interviews to create a framework with which to explore, evaluate and match theories that define social media usage by companies. It became clear from all of the interviews that social media as a tool is most effective when it captures the viewer’s interest through rich and entertaining content. This directed the theoretical research towards Engagement Theory and Content Marketing which look to emphasize the importance of communities, collaboration, interaction, and peer-sharing as the key drivers of a social media marketing campaign.

Distribution of immune response cells in the pelvic urethra and the prepuce of rams

The pathogens of the reproductive system in the male can penetrate and establish by ascending route, from to the prepuce to the urethra, accessory glands, epididymis and testicles. The aim of this paper is determine the distribution and number of cells involved in the immune response in prepuce and pelvic urethra of rams, without apparent clinical alterations in testicle, epididymis and prepuce. The distribution of some of the cells involved in the immune response at the level of the prepuce and the pelvic urethra was quantified in four one-year-old rams seronegative for B. ovis and A. seminis and without apparent lesions in the testicles, the epididymis, and the prepuce. At the moment of slaughter, samples were taken from the preputial fornix and the pelvic urethra and placed in 10% formalin and under freezing conditions. CD4, CD8, WC1, CD45RO, CD14 and CD1b cells were demonstrated by immunohistochemistry, and immunoglobulin-containing cells (ICC) of the IgA, IgG and IgM classes were demonstrated by immunofluorescence. The labeled cells present in the mucosa of both organs were counted with an image analyzer. The total number of cells was compared between both tissues and differentially between the epithelium and the connective tissue of the mucosa. Significant differences were found in the total number of CD4, CD45RO, and WC1 lymphocytes, in CD14 macrophages, and CD1b dendritic cells, with mean values being greater in the fornix than in the urethra (p<0.05) in all cases. Only dendritic cells were found in the prepuce. No differences were found in the number of CD8 lymphocytes between both organs. The ratio between each cell type in the connective and the intraepithelial tissues and between organs was 10/1 for CD4 in the fornix (p<0.05), against 7/1 in the urethra (p<0.05), while CD8 had a 1/1 distribution in both mucosae. The WC1 ratio was 5/1 in both mucosae (p<0.05). CD45RO labeling was 19/1 in the prepuce (p<0.05) and 1/1 in the urethra. IgA-containing cells did not show differences in the total number of cells in both tissues. In the urethra, no IgG-containing cells were observed and IgM-containing cells were scarce; in contrast, both cell types were present in the prepuce, in amounts greater than in the urethra (p<0.05). IgA-, IgG-, and IgM-containing cells were located in both organs in the mucosal connective tissue. The presence of antigen-presenting cells, macrophages, and dendritic cells, as well as of lymphocytes CD4, CD8 TCR γδ (WC1), IgA-, IgG and IgM positive cells, and CD45RO cells suggests that both mucosae may behave as inductive and effector sites for the mucosal immune response.
