Asunnottomuuden ratkaisumallit Helsingin Sanomien uutisoinnissa

Tutkimukseni käsittelee Helsingin Sanomien asunnottomuusuutisointia, josta etsin erilaisia ratkaisumalleja, jotka liittyivät asunnottomuuteen tai suoraan asunnottomuudesta johdettavissa olevaan ongelmaan. Tutkin artikkeleita ajanjaksolta 1.1.2013–30.6.2014. Valikoin asunnottomuutta käsitteleviä artikkeleita jotka sisälsivät ainakin yhden ratkaisumallin, ja kokosin lopulta 22 tutkimukseeni sopivaa artikkelia. Sovelsin sisällön analyysia, ja jaottelin näitä ratkaisumalleja kahteen ryhmään. Tutkin samalla minkälaisia ratkaisuja erilaiset asunnottomuusuutisointikehykset sisälsivät. Analysoin sitten millaisena ilmiönä asunnottomuus näyttäytyy Helsingin Sanomissa. Käytin tässä muokattua What's the problem represented to be- menetelmää. Tulokseni osoittivat, että Helsingin Sanomien asunnottomuusuutisoinnissa ennaltaehkäisevät toimenpiteet, sekä majoitukseen ja sen kehittämiseen tähtäävät toimenpiteet olivat yleisempiä ratkaisumalleja. Suurimmassa osassa ehdotetuista toimenpiteistä tähdättiin asunnottomien hyvinvoinnin parantamiseen. Ratkaisujen esittäjät olivat yleisemmin asiantuntijatahoja, kun taas kaikki muut tahot olivat selvä vähemmistö. Asunnottomat itse esiintyivät varsinaisena ratkaisumallin esittäjänä vain yhdessä tapauksessa. Asunnottomat näyttäytyivät yleisesti Helsingin Sanomien uutisoinnissa ihmisryhmänä joka tarvitsi yhteiskunnan apua. Vaikka uutisointi oli suurimmilta osin sympaattissävyistä, joissain tapauksissa asunnottomat saattoivat näyttäytyä taloudellisena rasitteena. Koska ratkaisumallien asunnottomien auttamiseen keskittyvät toimenpiteet olivat keskittyneet voimakkaasti majoitukseen, tämä nosti esiin kysymyksen muunlaisen tarpeellisen avun jäämisestä taka-alalle. Tätä näkemystä vahvisti WPR menetelmällä toteutettu analyysi. Asunnottomuuden aiheuttajana näkyi lähinnä edullisten asuntojen puute. Ongelmat joita asunnottomat kohtaavat ja joihin he voisivat tarvita apua olivat myös hyvin yksipuolisia. Asunnon puute ja asumispalvelut olivat lähestulkoon ainoat esiin nouseet asunnottomia koskevat ongelmat joita ratkaisumallit käsittelivät. Aiheen lisätutkimus olisi tarpeellista, jotta eri ryhmien intressien erottelu, ilmiön monipuolinen kokonaiskuva ja mahdollisimman puolueeton tiedon välitys tulisi esiin tiedon välityksessä ja päätöksen teossa.

Geographical Studies of Underwater Light Dynamics in the Coastal Archipelago of SW Finland, Baltic Sea

The underwater light field is an important environmental variable as it, among other things, enables aquatic primary production. Although the portion of solar radiation that is referred to as visible light penetrates water, it is restricted to a limited surface water layer because of efficient absorption and scattering processes. Based on the varying content of optical constituents in the water, the efficiency of light attenuation changes in many dimensions and over various spatial and temporal scales. This thesis discusses the underwater light dynamics of a transitional coastal archipelago in south-western Finland, in the Baltic Sea. While the area has long been known to have a highly variable underwater light field, quantified knowledge on the phenomenon has been scarce, patchy, or non-existent. This thesis focuses on the variability in the underwater light field through euphotic depths (1% irradiance remaining), which were derived from in situ measurements of vertical profiles of photosynthetically active radiation (PAR). Spot samples were conducted in the archipelago of south-western Finland, mainly during the ice-free growing seasons of 2010 and 2011. In addition to quantifying both the seasonal and geographical patterns of euphotic depth development, the need and usability of underwater light information are also discussed. Light availability was found to fluctuate in multiple dimensions and scales. The euphotic depth was shown to have combined spatio-temporal dynamics rather than separate changes in spatial and temporal dimensions. Such complexity in the underwater light field creates challenges in data collection, as well as in its utilisation. Although local information is needed, in highly variable conditions spot sampled information may only poorly represent its surroundings. Moreover, either temporally or spatially limited sampling may cause biases in understanding underwater light dynamics. Consequently, the application of light availability data, for example in ecological modelling, should be made with great caution.

Plaseboefekti hammaslääketieteessä

Plaseboefekti on yleisesti tunnettu mutta kliinisessä työssä melko vähän hyödynnetty ilmiö. Se on kuitenkin tärkeä osa kliinisiä lääketutkimuksia ja tiedostamattomasti osana kaikkia hoitotoimenpiteitä myös hammaslääketieteessä. Vaikka plaseboefektin olemassaolo on havaittu jo noin 200 vuotta sitten, ei plasebolle ole laadittu täsmällistä virallista määritelmää, ja edelleen myös muu ilmiöön liittyvä terminologia on monimuotoista. Yleensä plaseboefektillä tarkoitetaan hoitoon liittyviä vaikutuksia, jotka johtuvat tuntemattomista tai tarkoitusta vastaamattomista syistä. Plaseboefektin aiheuttamia haittavaikutuksia kutsutaan noseboksi. Plasebolääkkeiden ja -hoitojen määrääminen potilaalle ei lähtökohtaisesti ole hyväksyttävää. Potilaiden myönteisten odotusten vahvistaminen tehokkaiksi todistetuissa hoidoissa on kuitenkin kannattavaa, sillä se lisää kokonaishoitovaikutusta huomattavasti. Lääketieteelliseen tutkimustyöhön Maailman lääkäriliitto on laatinut eettisen ohjeiston plasebon käytöstä. Erityisesti viime vuosien käyttäytymis- ja lääketutkimukset, psykofysiologiset tutkimukset sekä aivojen kuvantamistutkimukset ovat antaneet paljon tietoa plaseboefektin luonteesta. Sen on todettu olevan todellinen neurobiologinen ilmiö, jonka vaikutukset perustuvat voimakkaiden odotusten laukaisemaan dopamiinin ja endogeenisten opioidien vapautumiseen. Plasebohoitojen vaikuttavuudesta eniten on tutkittu niiden analgeettista tehoa ja esimerkiksi päänsäryn ja orofasiaalisen kivun lievityksessä plasebohoidoilla on saatu hyviä hoitovasteita. Myös purentafysiologian alalla on tutkittu plaseboefektin aiheuttamaa kivun lievitystä: TMD-vaivoista johtuvissa kiputiloissa plasebohoito auttaa jopa 40 %:lla. Lisäksi plasebovaikutus on myös osana esimerkiksi purentakiskohoitojen vaikuttavuutta ja tulisi huomioida hoidon suunnittelussa sekä hoitotuloksen arvioinnissa.

Linguistic skills and trust creation in international business relationships

Today’s international business in highly related to crossing national, cultural and linguistic borders making communication and linguistic skills a vital part of the trade. The purpose of the study is to understand the role of linguistic skills in trust creation in international business relationships. Subobjectives are to discuss the importance of linguistic skills in international business context, to evaluate the strategic value of trust in business relationships and to analyze the extent to which linguistic skills affect trust formation. The scope is restricted to business-to-business markets. The theoretical background consists of different theories and previous studies related to trust and linguistic skills. Based on the theory a new LTS-framework is created to demonstrate a process model of linguistic skills affecting trust creation in international B2B relationships. This study is qualitative using interviews as a data collection method. Altogether eleven interviews were conducted between October 2014 and February 2015. All of the interviewees worked for organizations operating in the field of international business in B2B markets, spoke multiple languages and had a lot of experience in sales and negotiations. This study confirms that linguistic skills are an important part of international business. In many organizations English is used as lingua franca. However, there are several benefits of speaking the mother tongue of the customer. It makes people feel more relaxed and it makes the relationship more intimate and allows to continue developing it at a more personal level. From the strategic point of view trust creates competitive advantage to a company adding strategic value to the business. The data also supported the view that linguistic skills definitely impact the trust formation process. Quickness and easiness could be stated as the main benefits. It was seen that trust forms faster because both parties understand each other better and they become more open about information sharing within a shorter period of time. These findings and the importance of linguistic skills in trust creation should be acknowledged by organizations, especially regarding the human resource management. Boundary spanners are in key positions so special attention should be put into hiring and educating employees which then take care of company’s relationships. Eventually, these benefits are economical and affect to the profitability of the organization

Matalalämpötilaisten jätelämpövirtojen hyödyntäminen lämpöpumpuilla: Case Energiaväylä

Hyvinkään Sahanmäen teollisuusalueella tarkastellaan mahdollisuutta hyödyntää Saint Gobain Isoverin lasivillatehtaalla syntyvää ylijäämälämpöä alueen yritysten lämmittämiseen. Hukkalämpöä on tarkoitus ottaa talteen lauhduttamalla savukaasuihin sitoutunutta vesihöyryä ja siirtää lauhtumisessa vapautuva lämpö matalalämpötilaiseen verkkoon, Energiaväylään. Verkkoon liittyviin kohteisiin asennetaan lämpöpumput, joiden avulla kohteet hyödyntävät verkosta saatavaa lämpöä. Työssä lasketaan Energiaväylästä potentiaalisesti saatava lämpöteho ja sen riittävyys asiakkaille. Lasketaan myös lämpö- ja painehäviöt sekä pumppauskustannukset. Lisäksi määritetään verkkoon liittyvien yritysten saavuttamat kustannussäästöt perustuen niiden lämpöenergiankulutukseen, sekä hankkeen kokonaiskannattavuus. Työ ei kuvaa todellista tilannetta tarkasti, vaan perustuu lukuisiin oletuksiin ja arvioihin. Työn tuloksia voidaan hyödyntää kannattavuuden arvioinnissa, mutta niiden perusteella ei voida tehdä investointipäätöksiä. Tehtyjen oletuksien perusteella kohteet saavuttaisivat yhteensä noin 1,22 milj. euron vuosittaiset säästöt vaihtamalla maakaasulämmityksen Energiaväylään. Hanke on mahdollisesti kannattava viiden vuoden takaisinmaksuajalla. Kannattavuus riippuu kuitenkin oleellisesti lämpöpumppujen asennuskustannuksista, jotka tulee arvioida erikseen kullekin kohteelle.

Promoting Healthy Lifestyles with Personalized, APOE Genotype Based Health Information: The Effects on Psychological-, Health Behavioral and Clinical Factors

There is an increasing demand for individualized, genotype-based health advice. The general population-based dietary recommendations do not always motivate people to change their life-style, and partly following this, cardiovascular diseases (CVD) are a major cause of death in worldwide. Using genotype-based nutrition and health information (e.g. nutrigenetics) in health education is a relatively new approach, although genetic variation is known to cause individual differences in response to dietary factors. Response to changes in dietary fat quality varies, for example, among different APOE genotypes. Research in this field is challenging, because several non-modifiable (genetic, age, sex) and modifiable (e.g. lifestyle, dietary, physical activity) factors together and with interaction affect the risk of life-style related diseases (e.g. CVD). The other challenge is the psychological factors (e.g. anxiety, threat, stress, motivation, attitude), which also have an effect on health behavior. The genotype-based information is always a very sensitive topic, because it can also cause some negative consequences and feelings (e.g. depression, increased anxiety). The aim of this series of studies was firstly to study how individual, genotype-based health information affects an individual’s health form three aspects, and secondly whether this could be one method in the future to prevent lifestyle-related diseases, such as CVD. The first study concentrated on the psychological effects; the focus of the second study was on health behavior effects, and the third study concentrated on clinical effects. In the fourth study of this series, the focus was on all these three aspects and their associations with each other. The genetic risk and health information was the APOE gene and its effects on CVD. To study the effect of APOE genotype-based health information in prevention of CVD, a total of 151 volunteers attended the baseline assessments (T0), of which 122 healthy adults (aged 20 – 67 y) passed the inclusion criteria and started the one-year intervention. The participants (n = 122) were randomized into a control group (n = 61) and an intervention group (n = 61). There were 21 participants in the intervention Ɛ4+ group (including APOE genotypes 3/4 and 4/4) and 40 participants in the intervention Ɛ4- group (including APOE genotypes 2/3 and 3/3). The control group included 61 participants (including APOE genotypes 3/4, 4/4, 2/3, 3/3 and 2/2). The baseline (T0) and follow-up assessments (T1, T2, T3) included detailed measurements of psychological (threat and anxiety experience, stage of change), and behavioral (dietary fat quality, consumption of vegetables, - high fat/sugar foods and –alcohol, physical activity and health and taste attitudes) and clinical factors (total-, LDL- HDL cholesterol, triglycerides, blood pressure, blood glucose (0h and 2h), body mass index, waist circumference and body fat percentage). During the intervention six different communication sessions (lectures on healthy lifestyle and nutrigenomics, health messages by mail, and personal discussion with the doctor) were arranged. The intervention groups (Ɛ4+ and Ɛ4-) received their APOE genotype information and health message at the beginning of the intervention. The control group received their APOE genotype information after the intervention. For the analyses in this dissertation, the results for 106/107 participants were analyzed. In the intervention, there were 16 participants in the high-risk (Ɛ4+) group and 35 in the low-risk (Ɛ4-) group. The control group had 55 participants in studies III-IV and 56 participants in studies I-II. The intervention had both short-term (≤ 6 months) and long-term (12 months) effects on health behavior and clinical factors. The short-term effects were found in dietary fat quality and waist circumference. Dietary fat quality improved more in the Ɛ4+ group than the Ɛ4- and the control groups as the personal, genotype-based health information and waist circumference lowered more in the Ɛ4+ group compared with the control group. Both these changes differed significantly between the Ɛ4+ and control groups (p<0.05). A long-term effect was found in triglyceride values (p<0.05), which lowered more in Ɛ4+ compared with the control group during the intervention. Short-term effects were also found in the threat experience, which increased mostly in the Ɛ4+ group after the genetic feedback (p<0.05), but it decreased after 12 months, although remaining at a higher level compared to the baseline (T0). In addition, Study IV found that changes in the psychological factors (anxiety and threat experience, motivation), health and taste attitudes, and health behaviors (dietary, alcohol consumption, and physical activity) did not directly explain the changes in triglyceride values and waist circumference. However, change caused by a threat experience may have affected the change in triglycerides through total- and HDL cholesterol. In conclusion, this dissertation study has given some indications that individual, genotypebased health information could be one potential option in the future to prevent lifestyle-related diseases in public health care. The results of this study imply that personal genetic information, based on APOE, may have positive effects on dietary fat quality and some cardiovascular risk markers (e.g., improvement in triglyceride values and waist circumference). This study also suggests that psychological factors (e.g. anxiety and threat experience) may not be an obstacle for healthy people to use genotype-based health information to promote healthy lifestyles. However, even in the case of very personal health information, in order to achieve a permanent health behavior change, it is important to include attitudes and other psychological factors (e.g. motivation), as well as intensive repetition and a longer intervention duration. This research will serve as a basis for future studies and its information can be used to develop targeted interventions, including health information based on genotyping that would aim at preventing lifestyle diseases. People’s interest in personalized health advices has increased, while also the costs of genetic screening have decreased. Therefore, generally speaking, it can be assumed that genetic screening as a part of the prevention of lifestyle-related diseases may become more common in the future. In consequence, more research is required about how to make genetic screening a practical tool in public health care, and how to efficiently achieve long-term changes.

The nature experiences of wilderness recreation leaders : throwing a stone

Through this descriptive exploratory study, the ways that wilderness recreation leaders experience nature are illuminated, deconstructing the assumed environmental benefits of and practices used in outdoor recreation (Haluza-Delay, 2001). This study also offers a foundation for advancing an environmental ethic among wilderness recreation leaders, participants, and organizations. With the continued degradation of and threats to natural environments, and the rising popularity of outdoor recreation participation, the outdoor recreation professional can be a leader in promoting human reconnections to the Earth (Henderson, 1999). Leaders of outdoor recreation experiences play an important role in encouraging these revived relationships to natural settings and can contribute to the necessary environmental consciousness shift needed within Western society (Hanna, 1995; Jordan, 1996). The purpose of this research was to describe the lived-experience in nature of wilderness recreation leaders. Specifically, a phenomenological method of inquiry was used to describe the meaning of nature, the connections and relationships to nature, and the behaviours and emotions experienced in nature by a group of wilderness canoe trip leaders employed by a residential summer camp. In addition to the implications of this research, achieving this outcome provides a rich descriptive understanding of wilderness leaders' experiences—a basis from which to extend future research endeavours and programmatic practices that promote effective environmental outcomes of outdoor recreation participation. Each of the five study participants was employed in the summer of 2003 by an Ontario residential summer camp organization that sponsors extended wilderness river canoe trips for youth. Two in-depth and semi-structured interviews were performed with each participant, asking them to reflect on the canoe trip that they led for the summer camp organization during 2003. Phenomenological data was analyzed according to Colaizzi's (1978) thematic analysis process. Consistent with van Manen's (1997) emphasis on phenomenological writing, the final result presents the essence of the nature experiences of wilderness recreation leaders in the format of a narrative description. This narrative piece is the culmination of this research effort. Throughout the journey, however, various foundations within the outdoor recreation field, such as minimum impact principles, environmentally responsible behaviours, anthropocentric and ecocentric worldviews, and effective leadership are deconstructed and discussed.

Exchange reactions of organic halides and organo-silicon compounds with boron tribromide and boron triiodide

Reactions of the boron halides with organic halides and organo-silicon compounds have been investigated. The results show exchange of halogens between the BX3 (X = Br# 1) and the organic halidef exchange of the halogen of the C-X bond being proved. The rates of halogen exchange vary. Reaction of the heavier halides with organo-silicon compounds indicated that the silicon-carbon bonds ruptured in the absence of electronegative atom attached to the silicon. The presence of an electronegative atom (halogen or oxygen) attached to the silicon causes the bond between the silicon and the electronegative atom to be preferentially broken. Products of exchange reactions of the boron halides and the organic halides or the organo-silicon compounds were studied by use of 1H NMR and GC/MS. From these results some possible mechanisms for the exchange reactions are postulated, but further work is indicated to prove the real courses of the reactions

Studies of nucleophilic attack on tris (pentafluorophenyl) phosphine and its oxides

The reaction of tris(pentafluorophenyl)phosphine [5] with the nucleophiles dimethyl formamide (DMF), hexamethylphosphoric triamide (HMPA), diethyl formamide (DEF), hexaethylphosphoric triamide (HEPA), hydrazine, N,N-dimethyl hydrazine (in presence and/or absence of KF), phenylhydrazine, ammonium hydroxide, formamide, aniline, sodium hydrogen sulfide, and hexaethylphosphorous triamide was investigated. The reaction of [5] with DMF and HMPA gave the same product, namely tris-[4-(N,N-dimethylamino)-2,3,5,6-tetrafluorophenyl]phosphine [12] but in higher yield in the case of HMPA. Compound (5] also reacted with DEF to give tris[4-(N,N-diethylamino)-2,3,5,6-tetrafluorophenyl] phosphine [14]. When [51 was treated with HEPA, it gave a mixture of bis(pentafluorophe~yl)-(N,N-diethylamino-tetrafluorophenyl)phosphine, pentafluorophenyl-bis-(N,N-diethylamino-tetrafluorophenyl)phosphine and tris (N,N-diethylamino-tetrafluorophenyl)phosphine. Treatment of [5] with aqueeus hydrazine solution in excess ethanol gave tris(4-hydrazo-2,3,4,6-tetrafluorophenyl)phosphine [1s1 in high yield while reaction with aqueous hydrazine led to C-P cleavage and production of tetrafluorophenyl hydrazine. With N,N-dimethyl hydrazine, [5] gave tris(4-N,N-dimethylhydrazine-2,3,5,6-tetrafluorophenyl) phosphine {20j. The latter could be obtained in higher yield and shorter reaction time, by the addition of KF. The reaction of compound {51 with phenylhydrazine in THF gave bis(pentafluorophe~yl)-4-S-phenylhydrazino- 2,3,5,6-tetrafluorophenyl phosphine [22] in low yield. Reaction of [5] with ammonium hydroxide in THF at high pressure in the presence of KF gave tris-~4-amino-2,3,5,6-tetrafluorophenyl)phosphine [25]. Similarly, formamide led to a mixture of (C6F4NHZ)3P, (C6F4NHZ)ZPC6FS, (C6F4NHZ)ZPC6F4NHCHO, and C6F4NHZP(C6Fs)(C6F4NHCHO). When [5] was treated with aniline, a mixture of mono-, di-, and tri-substituted products was obtained. Sodium hydrogen sulfide in ethylene glycol/ pyridine led to C-P cleavage and the isolation of pentafluorobenzene and tetrafluorothiophenol. Reaction of [5] and its oxide [35] with different alkoxides in the corresponding alcohols led mainly to C-P bond cleavage products, with the exception of one case where sodium methoxide was used in ether, and which led to tris-(4-methoxy-2,3,9,6-tetrafluorophenyl)phosphine [37]. On the basis of various spectroscopic data, it was concluded that the para position in compound [5] was generally the favoured site of attack.
