Elemental analysis of wood materials by external millibeam thick target PIXE

PIXE (Particle Induce X-ray Emission spectrometry) was used for analysing stem bark and stem wood of Scots pine, Norway spruce and Silver birch. Thick samples were irradiated, in laboratory atmosphere, with 3 MeV protons and the beam current was measured indirectly using a photo multiplicator (PM) tube. Both point scans and bulk analyses were performed with the 1 mm diameter proton beam. In bulk analyses, whole bark and sectors of discs of the stem wood were dry ashed at 550 ˚C. The ashes were homogenised by shaking and prepared to target pellets for PIXE analyses. This procedure generated representative samples to be analysed, but the enrichment also enabled quantification of some additional trace elements. The ash contents obtained as a product of the sample preparation procedure also showed to be of great importance in the evaluation of results in environmental studies. Spot scans from the pith of pine wood outwards, showed clearly highest concentrations of manganese, calcium and zinc in the first spot irradiated, or 2-3 times higher than in the surrounding wood. For stem wood from the crown part of a pine this higher concentration level was found in the first four spots/mms, including the pith and the two following growth rings. Zinc showed increasing concentrations outwards in sapwood of the pine stem, with the over-all lowest concentrations in the inner half of the sapwood. This could indicate emigration of this element from sapwood being under transformation to heartwood. Point scans across sapwood of pine and spruce showed more distinct variations in concentrations relative to hearth wood. Higher concentrations of e.g. zinc, calcium and manganese were found in earlywood than in denser latewood. Very high concentrations of iron and copper were also seen for some earlywood increments. The ash content of stem bark is up to and order higher than for the stem wood. However, when the elemental concentration in ashes of bark and wood of the same disc were compared, these are very similar – this when trees are growing at spots with no anthropogenic contamination from the atmosphere. The largest difference was obtained for calcium which appeared at two times high concentrations in ashes of bark than in ashes of the wood (ratio of 2). Pine bark is often used in monitoring of atmospheric pollution, where concentrations in bark samples are compared. Here an alternative approach is suggested: Bark and the underlying stem wood of a pine trees are dry ashed and analysed. The elemental concentration in the bark ash is then compared to the concentration of the same element in the wood ash. Comparing bark to wood includes a normalisation for the varying availability of an element from the soil at different sites. When this comparison is done for the ashes of the materials, a normalisation is also obtained for the general and locally different enrichment of inorganic elements from wood to bark. Already a ratio >2 between the concentration in the bark ash and the concentration in the wood ash could indicate atmospheric pollution. For monitoring where bark is used, this way of “inwards” comparison is suggested - instead of comparing to results from analyses of bark from other trees (read reference areas), growing at sites with different soil and, locally, different climate conditions. This approach also enables evaluation of atmospheric pollution from sampling of only relative few individual trees –preferable during forest felling.

Investigation Into the Timeliness of the Death Notification to the Surviving Spouse of a Motor Vehicle Accident Victim, 2005

Report: #05-02 Kirke C. Quinn, Attorney for Jo Anne Holland, first contacted the Ombudsman by letter dated January 2, 2004. Quinn also addressed his letter to the Governor’s Office, Iowa State Patrol (ISP), and Iowa Department of Public Safety (DPS). Quinn characterized his letter as a complaint against ISP regarding “the method and manner of reporting the death of Ross Holland to his surviving spouse.” According to Quinn, Mrs. Holland “went through hours of misery as a result of the patrol’s inattention to a tragic situation.” On January 7, 2004, the Ombudsman asked ISP Major Gary Hoskins, Supervisor of Field Operations, how ISP and DPS intended to respond to Mr. Quinn’s letter. Major Hoskins stated he would refer Quinn’s letter of complaint to DPS’ Professional Standards Bureau (PSB) for investigation and response. After speaking with Major Hoskins, the Ombudsman told Mr. Quinn that DPS would do an internal investigation and if he were not satisfied with the results he could contact the Ombudsman again. On March 29, 2004, Mr. Quinn contacted the Ombudsman and stated he was not satisfied with DPS’ response. Quinn stated he would send a copy of the response to the Ombudsman, along with a letter stating his outstanding issues and concerns. In his letter to the Ombudsman, dated May 5, Quinn simply stated: “Please find enclosed [a] copy of the letter received from the Department of Public Safety. We think this is an absolute outrage. We welcome your input.”

Bassossa Erik Lindström

Opinnäytetyössäni tavoitteena on saada tietoa Erik Lindströmistä basistina, sekä selvittää, mitkä tekijät ovat vaikuttaneet hänen menestyksekkääseen basistin uraansa. Esitän hypoteesina, että ominaisuudet, joita freelancebasistilta edellytetään, ovat varsin samanlaisia nykyään, kuin Lindströmin uran alkuvaiheilla 1940-luvulla. Opinnäytetyötäni varten olen haastatellut Lindströmiä ja kirjoittanut hänen bassonsoittourastaan musiikkiharrastuksen alusta alkaen. Haastattelu on liitteenä CD-muodossa työn takakannessa ja sen kesto on 60 minuuttia. Erik Lindström syntyi Helsingissä 29.5.1922. Hänen isänsä oli aktiivinen amatöörimuusikko, jonka kanssa Erik oli jo 10-vuotiaana ensimmäisellä tanssikeikalla. Ensimmäinen soitin oli viulu, jota hän soitti korvakuulolta. Erik tutustui myöhemmin jazzia harrastaviin ikätovereihinsa Cotton Clubilla. Tästä porukasta alkoi muodostua yhtyeitä, joissa Lindström soitti bassoa. Hän tutki amerikkalaisten esikuviensa soittoa ja opiskeli klassista kontrabasson soittoa kolme vuotta. Luvussa bassonsoiton opiskelu käsitellään jazzinnostusta ja esikuvien vaikutusta, sekä Lindströmin tärkeänä pitämiä asioita, kuten soundia, timea ja yhtyesoittoa. Lisäksi pohditaan korvakuulosoittoa ja nuotinlukua. Lindströmistä kehittyi nopeasti yksi Helsingin kysytyimpiä basisteja. Valittuaan ammattimuusikon uran hän asennoitui kunnianhimoisesti työhönsä ja kehitti itseään niin teoreettisesti kuin taidollisestikin. Hän työskenteli ahkerasti studioissa soittaen erilaisissa tuotannoissa. Ammattilaisura-osassa käsiteltäviä asioita ovat asenne, instrumentit, keikat ja uran kohokohdat. Lopuksi Lindström antaa ohjeita nuoremmille soittajille. Tämän tutkimuksen valossa freelancebasistilta vaadittavat ominaisuudet eivät ole juuri muuttuneet Erik Lindströmin uran alkuajoista. Lindström pitää tärkeänä hypoteesissa mainitsemiani ominaisuuksia: soundia, taimia, musiikin omaksumistaitoja sekä täsmällisyyttä ja luotettavuutta niin musiikillisissa kuin käytännön asioissakin.

Show me your brain! Stories of interdisciplinary knowledge creation in practice. Experiences and observations from Aalto Design Factory, Finland.

This dissertation centres on the themes of knowledge creation, interdisciplinarity and knowledge work. My research approaches interdisciplinary knowledge creation (IKC) as practical situated activity. I argue that by approaching IKC from the practice-based perspective makes it possible to “deconstruct” how knowledge creation actually happens, and demystify its strong intellectual, mentalistic and expertise-based connotations. I have rendered the work of the observed knowledge workers into something ordinary, accessible and routinized. Consequently this has made it possible to grasp the pragmatic challenges as well the concrete drivers of such activity. Thus the effective way of organizing such activities becomes a question of organizing and leading effective everyday practices. To achieve that end, I have conducted ethnographic research of one explicitly interdisciplinary space within higher education, Aalto Design Factory in Helsinki, Finland, where I observed how students from different disciplines collaborated in new product development projects. I argue that IKC is a multi-dimensional construct that intertwines a particular way of doing; a way of experiencing; a way of embodied being; and a way of reflecting on the very doing itself. This places emphasis not only the practices themselves, but also on the way the individual experiences the practices, as this directly affects how the individual practices. My findings suggest that in order to effectively organize and execute knowledge creation activities organizations need to better accept and manage the emergent diversity and complexity inherent in such activities. In order to accomplish this, I highlight the importance of understanding and using a variety of (material) objects, the centrality of mundane everyday practices, the acceptance of contradictions and negotiations well as the role of management that is involved and engaged. To succeed in interdisciplinary knowledge creation is to lead not only by example, but also by being very much present in the very everyday practices that make it happen.

Posttraumatic stress disorder symptoms might be destroying your intimacy : a test of mediational models in a community sample of couples

The present research focused on the pathways through which the symptoms of posttraumatic stress disorder (PTSD) may negatively impact intimacy. Previous research has confirmed a link between self-reported PTSD symptoms and intimacy; however, a thorough examination of mediating paths, partner effects, and secondary traumatization has not yet been realized. With a sample of 297 heterosexual couples, intraindividual and dyadic models were developed to explain the relationships between PTSD symptoms and intimacy in the context of interdependence theory, attachment theory, and models of selfpreservation (e.g., fight-or-flight). The current study replicated the findings of others and has supported a process in which affective (alexithymia, negative affect, positive affect) and communication (demand-withdraw behaviour, self-concealment, and constructive communication) pathways mediate the intraindividual and dyadic relationships between PTSD symptoms and intimacy. Moreover, it also found that the PTSD symptoms of each partner were significantly related; however, this was only the case for those dyads in which the partners had disclosed most everything about their traumatic experiences. As such, secondary traumatization was supported. Finally, although the overall pattern of results suggest a total negative effect of PTSD symptoms on intimacy, a sex difference was evident such that the direct effect of the woman's PTSD symptoms were positively associated with both her and her partner's intimacy. I t is possible that the Tend-andBefriend model of threat response, wherein women are said to foster social bonds in the face of distress, may account for this sex difference. Overall, however, it is clear that PTSD symptoms were negatively associated with relationship quality and attention to this impact in the development of diagnostic criteria and treatment protocols is necessary.

Resiliencia organizacional y capital psicológico

Desde la noción universal sobre la empresa como un sistema de interacción con un entorno determinado para alcanzar un objetivo, de manera planificada y en función de satisfacer las demandas de un mercado mediante la actividad económica, su viabilidad, sostenibilidad y crecimiento dependerán, por supuesto, de una serie de estrategias adecuadas no solo para tales fines, sino también para enfrentar diversidad de agentes endógenos y exógenos que puedan afectar el normal desempeño de su gestión. Estamos hablando de la importancia de la resiliencia organizacional y del Capital Psicológico. En un escenario tan impredecible como el de la economía mundial, donde la constante son los cambios en su comportamiento —unos propios de su dinámica e interdependencia, naturales de fenómenos como la globalización, y otros derivados de eventos disruptivos— hoy más que nunca es necesario implementar el modelo de la empresa resiliente, que es aquella entidad capaz de adaptarse y recuperarse frente a una perturbación. Al mismo tiempo, más allá de su tamaño, naturaleza u objeto social, es indispensable reconocer básicamente que toda organización está constituida por personas, lo cual implica la trascendencia que para su funcionamiento tiene el factor humano-dependiente, y por lo tanto se crea la necesidad de promover el Capital Psicológico y la resiliencia a nivel de las organizaciones a través de una cultura empresarial.

Tapping into your people: successfully managing idea generation in organisations

Over the past few years, innovation has increasingly garnered the headlines as one of the core competencies every sustainable organisation must have. Yet, it is the idea which is the foundation of any innovation. This paper draws together knowledge about idea generation, and its management, and how the process of encouraging ideas, creativity and then managing them effectively will enhance the opportunities of successfully finding and implementing innovations which will add value to the organisation and its stakeholders. Extensive review of literature in the field of idea and innovation management, as well as a study of Souza Cruz¿s recently conceptualised and implemented Idea Management programme has brought together the many facets involved in successfully harnessing and implementing ideas.

Better than my pride is your misfortune: the impact of schadenfreude on decision-making

Investigações anteriores relacionadas ao schadenfreude concentraram-se nos fatores que provocam o prazer no infortúnio do outro. A presente pesquisa tem como objetivo investigar o impacto do schadenfreude na tomada de decisão. Dois estudos (um em laboratório e uma em campo) abordam o impacto do schadenfreude em decisões realizadas no passado e no futuro em eventos desportivos. O primeiro estudo confronta sentimentos de orgulho em uma vitória do time favorito contra os sentimentos de perda schadenfreude de uma equipe rival. Os resultados mostraram que as pessoas preferiam enviar notícias sobre a vitória da equipe favorita (orgulho) ao invés da perda do time rival (schadenfreude) quando as diferenças de pontuação no jogo eram pequenas (por exemplo: time favorito 1 x 0 outro, contra, o time rival 0 x 1 favorito). No entanto, as pessoas eram mais propensas a fazer a escolha schadenfreude (por exemplo, escolher o envio de uma notícia sobre a derrota de um time rival) quando o resultado era alto (por exemplo, time favorito 5 x 0 rival, contra, time rival 0 x 5 favorito). O segundo estudo no campo examina como schadenfreude influencia a vontade de apostar contra um time rival. Para responder a esse problema, a preferência da equipe do participante é avaliada (Participantes que apoiam time alvo contra os que apoiam o rival). Uma manipulação de louvor é adicionada, tal que os consumidores vejam ou não um elogio à equipe alvo enquanto eles estão fazendo uma aposta sobre o resultado da partida. Os resultados mostram que os torcedores do time alvo não foram influenciados pela manipulação de louvor. No entanto, torcedores do time rival aumentaram sua probabilidade de aposta contra o time alvo (ou seja, mostraram um comportamento que envolve o schadenfreude) quando esta foi elogiada antes do jogo.

Speak now or forever hold your peace: an empirical investigation of whistleblowing in Brazilian organizations

À medida que ajudam as organizações a prevenir condutas irregulares e a manter um ambiente de trabalho mais éticos, as denúncias (whistleblowing) são frequentemente apontadas pela literatura como um benefício à sociedade como um todo. Entretanto, pouco se sabe a respeito de muitos aspectos associados à decisão de denunciar uma irregularidade. No Brasil, em especial, onde o assunto permanece sendo negligenciado por pesquisadores, elementos culturais específicos podem obstruir o caminho da denuncia, além de impor restrições à generalização dos resultados de pesquisas anteriores, quase sempre voltadas para a realidade anglo-saxônica. Com base nesses pressupostos, este estudo busca identificar os antecedentes do whistleblowing interno nas organizações brasileiras. De modo geral, os resultados da pesquisa empírica realizada com uma ampla amostra de profissionais oriundos de empresas púbicas e privadas dão suporte ao modelo proposto e reforçam a noção de que o ato de denunciar é o resultado complexo da interação entre fatores da organização, do indivíduo da situação observada. Em particular, os resultados sugerem que os indivíduos são mais propensos a realizar a denúncia quando a irregularidade observada é percebida como grave e quando a própria denuncia é vista como um curso de ação ético. Por outro lado, os indivíduos podem optar pelo silêncio se o alvo da denúncia for alguém com alto status na organização, se eles não sentirem apoio da organização ou se temerem retaliações. A influência negativa do medo de retaliação sobre a intenção de denunciar, contudo, pode ser atenuada se o indivíduo está convencido de que o correto a fazer é denunciar. Por fim, os resultados também sugerem que profissionais em posição gerencial são mais propensos a denunciar irregularidades do que os demais membros de uma organização. As implicações desses resultados, bem como as limitações e contribuições do estudo para a teoria e para a prática são discutidas em detalhe, juntamente com sugestões para pesquisas futuras.

Not your mother's Latinas : film representations for a new millennium

This dissertation seeks to contribute to film, feminist and Latino/a studies by exploring the construction and ideological implications of representations of Latinas in four recent, popular U.S. films: Girlfight (Kusama 2000), Maid in Manhattan (Wang 2002), Real Women Have Curves (Cardoso 2002) and Spanglish (Brooks 2004). These films were released following a time of tremendous growth in the population and the political and economic strength of the Latina/o community as well as a rise in popularity and visibility in the 1990s of entertainers like Selena and actresses such as Jennifer Lopez and Salma Hayek. Drawing on the critical concepts of hybridity, Latinidad, and Bakhtinian dialogism, I analyze these films from a cultural and historical perspective to consider whether and to what degree, assuming changes in the situation of Latinas/os in the 1990’s, representations of Latinas have also changed. Specifically, in this dissertation I consider the ways in which the terrain of the Latina body is articulated in these films in relation to competing societal, cultural and familial conflicts, focusing on the body as a site of struggle where relationships collide, interact and are negotiated. In this dissertation I argue that most of the representations of Latinas in these films defy easy categorization, featuring complex characters grappling with economic issues, intergenerational differences, abuse, mother-daughter relationships, notions of beauty, familial expectations and the very real tensions between Latina/o cultural beliefs and practices and the dominant Anglo culture of the United States. Specifically, I argue that narrative and visual representation of Latina bodies in these films reflects a change in the Latinas offered for consumption to film viewers, presenting us with what some critics have called ‘emergent’ Latinas: conflicted and multilayered representations that in some cases challenge dominant ideologies and offer new demonstrations of Latina agency.
