Persistence of cognitive impairment and its negative impact on psychosocial functioning in lithium-treated, euthymic bipolar patients: a 6-year follow-up study.

BACKGROUND: Previous cross-sectional studies report that cognitive impairment is associated with poor psychosocial functioning in euthymic bipolar patients. There is a lack of long-term studies to determine the course of cognitive impairment and its impact on functional outcome. Method A total of 54 subjects were assessed at baseline and 6 years later; 28 had DSM-IV TR bipolar I or II disorder (recruited, at baseline, from a Lithium Clinic Program) and 26 were healthy matched controls. They were all assessed with a cognitive battery tapping into the main cognitive domains (executive function, attention, processing speed, verbal memory and visual memory) twice over a 6-year follow-up period. All patients were euthymic (Hamilton Rating Scale for Depression score lower than 8 and Young mania rating scale score lower than 6) for at least 3 months before both evaluations. At the end of follow-up, psychosocial functioning was also evaluated by means of the Functioning Assessment Short Test. RESULTS: Repeated-measures multivariate analysis of covariance showed that there were main effects of group in the executive domain, in the inhibition domain, in the processing speed domain, and in the verbal memory domain (p<0.04). Among the clinical factors, only longer illness duration was significantly related to slow processing (p=0.01), whereas strong relationships were observed between impoverished cognition along time and poorer psychosocial functioning (p<0.05). CONCLUSIONS: Executive functioning, inhibition, processing speed and verbal memory were impaired in euthymic bipolar out-patients. Although cognitive deficits remained stable on average throughout the follow-up, they had enduring negative effects on psychosocial adaptation of patients.

Ego identity in adolescence: preliminary validation of a French short-form of the EIPQ

Following the seminal work on personal identity of Erikson, Marcia's identity status model has been one of the most enduring paradigms. The Ego Identity Process Questionnaire (EIPQ; Balistreri, Busch-Rossnagel, & Geissinger, 1995) is a widely used measure of identity status. The purpose of this study was to evaluate the factor structure and the reliability of a French version of the EIPQ. The hypothesized structures were not confirmed. In light of the failed attempts to validate the original version, an alternative short-form version of the EIPQ (EIPQ-SF), maintaining the integrity of the original model, was developed in one sample and cross-validated in another sample. Additionally, theoretically consistent associations between the EIPQ-SF dimensions and self-esteem confirmed convergent validity. Globally, the results indicated that the French short-version of the EIPQ might be a useful instrument for the assessment of the identity statuses in adolescence and emerging adulthood.

Drug abuse, brain calcification and glutamate-induced neurodegeneration

Positive and negative reinforcing systems are part of the mechanism of drug dependence. Drugs with abuse potential may change the manner of response to negative emotional stimuli, activate positive emotional reactions and possess primary reinforcing properties. Catecholaminergic and peptidergic processes are of importance in these mechanisms. Current research needs to understand the types of adaptations that underlie the particularly long-lived aspects of addiction. Presently, glutamate is candidate to play a role in the enduring effects of drugs of abuse. For example, it participates in the chronic pathological changes of corticostriatal terminals produced by methamphetamine. At the synaptic level, a link between over-activation of glutamate receptors, [C(a2+)](i) increase and neuronal damage has been clearly established leading to neurodegeneration. Thus, neurodegeneration can start after an acute over-stimulation whose immediate effects depend on a diversity of calcium-activated mechanisms. If sufficient, the initial insult results in calcification and activation of a chronic on-going process with a progressive loss of neurons. At present, long-term effects of drug dependence underlie an excitotoxicity process linked to a polysynaptic pathway that dynamically regulates synaptic glutamate. Retaliatory mechanisms include energy capability of the neurons, inhibitory systems and cytoplasmic calcium precipitation as part of the neuron-glia interactions. This paper presents an integrated view of these molecular and cellular mechanisms to help understand their relationship and interdependence in a chronic pathological process that suggest new targets for therapeutic intervention.

De ratones y hombres. Maus, de Art Spiegelman

This article analyses the cómic book Maus, by Art Spiegelman (1986-1991), from two angles: as a work of art dealing with the Holocaust, and as a cómic that subverts the fictional tradition of the genre, opening itself up to history and the narration of reality. Maus, the first cómic book to treat the topic of the Holocaust in depth, was written by a second-generation witness. It is a story of both physical survival and enduring trauma in the family. At the same time, an analysis of the stratevival and enduring trauma in the family. At the same time, an analysis of the strateof the traditional cómic reveals how Spiegelman has used the genre to recount, instead of fiction and for the first time, a historically authentic biographical tale

Expanding to institutionally different countries. Reasons, Firm International Experience, and Entry Mode Choice

We examine entry mode choice and its consequences when a multinational enterprise (MNE) expands into an institutionally different country. We argue that discussions of entry mode should distinguish between informal (e.g., culture) and formal (e.g., laws) institutions, and should take into account not just the home country of the MNE and its distance to the focal host country, but the MNE's overall footprint and experience across the world in general, especially in countries with an institutional structure that is similar to that of the focal host country. Specifically, we argue that firms with experience in countries with different informal institutions will be more likely to enter via acquisitions than firms without such experience, that such experience will not matter as much in the case of formal institutions, and that such firms will exit more quickly when they enter via equity alliances than through full acquisitions. We also distinguish between balanced and unbalanced alliances and argue that balanced alliances will be more enduring, but only when the host country is culturally (not legally) different from the other countries where the MNE has experience. Our arguments suggest that entry mode should be conditioned on a firm's experience in other markets, and that intercountry differences in formal versus informal institutions have distinct influences on entry mode.

Yhdysvaltojen ja koalition joukkojen tappiot Afganistanin sodassa 19.10.2001 - 31.12.2009

Työn aiheena on Yhdysvaltojen ja koalition joukkojen tappiot Afganistanin sodassa 2001 – 2009. Syyskuun 2001 terrori-iskujen jälkeen Yhdysvallat aloittivat sotilaalliset operaatiot Afganistanissa nopeasti. Aluksi operaatio sai nimen ”Infinite Justice”, joka melko pian muutettiin ”Enduring Freedomiksi”. Afganistanin operaation alkuperäisenä tavoitteena oli vaihtaa Afganistanin hallinto ja tuhota maassa olevat Al-Qaidan ja Talibanin aseellisetvoimat. Nämä tavoitteet saavutettiin varsin nopeasti. Vuoteen 2002 loppuun mennessä Taliban ja Al- Qaida oli sotilaallisesti lyöty Afganistanissa. Tärkeimpiä johtohenkilöitä ei kuitenkaan saatu eliminoitua ja tappion ollessa varma Talibanin ja Al-Qaidan edustajat siirtyivät heimoalueelle Pakistaniin. Vuodesta 2003 alkaen Afganistanin sotaa voidaan pitää kumouksellisena sotana, jossa kapinalliset yrittävät kukistaa vallalla olevan hallinnon. Kuten monissa muissakin kumouksellisissa sodissa myös Afganistanissa on käynyt niin, että sieltä irtautuminen on muodostunut ongelmaksi. Operaation pitkittyessä, se vaati kokoajan lisää resursseja.

Aseistettujen UAV:iden käyttö Afganistanin sodassa

Nykyajan sodankäynnissä jatkuvan tilannekuvan ylläpitäminen, kaukovaikuttaminen ja täsmäiskut ovat nousseet tärkeisiin rooleihin. Perinteisten lentokoneiden rinnalle taistelukentille ovat tulleet miehittämättömät ilma-alukset, joiden käyttö on lisääntynyt valtavasti 2000-luvun puolella. Tutkimuksessa tarkastellaan Afganistanin sodassa käytettyjä miehittämättömiä ilma-aluksia ja niiden käyttöperiaatteita. Tutkielma on laadullinen eli kvalitatiivisin menetelmin tehty tutkimus, jonka menetelmät painottuvat asiakirja- ja tekstianalyysiin. Päätutkimuskysymyksenä on ”Mitä taktisia elementtejä UCAV tuo taisteluun?”. Tutkimuksessa esitellään UAV yleisesti sekä Afganistanin sodassa käytetyt mallit. Tutkielma jakautuu lukuihin, joista ensimmäisessä esitellään UAV:ta teknisesti ja toisessa luvussa tarkastellaan UAV:iden käyttöä Afganistanissa. Kolmannessa pääluvussa tarkastellaan UAV:iden etuja ja heikkouksia lentokoneisiin verrattuna. Johtopäätöksissä saadut tulokset tiivistetään vastauksiksi tutkimuskysymyksiin. Tutkielman ajankohtaisuutta korostaa UAV-operaatioiden lisääntyminen sodissa jatkuvasti ja niiden lentotuntimäärien huomattava kasvu verrattuna lentokoneisiin. Myös Suomen Puolustusvoimat on päättänyt hankkia lisää tiedusteluun sopivia kevyitä UAV:ita.

Porin Kuudennen osan tarinoista rakennettu kulttuuriperintö

Tutkimus käsittelee viranomaisten ja asukkaiden välistä vuorovaikutusta kaavaprosessin aikana. Tutkimusalueena on valtakunnallisesti merkittäväksi kulttuuriympäristöksi luokiteltu Porin Kuudes osa, joka on yksi laajimmista yhtenäisenä säilyneistä 1800-luvun lopun puukaupunkialueista Suomessa. Hermeneuttis-fenomenologista otetta soveltava tutkimus perustuu muistitietoaineistoon, joka avaa näkökulman paikallisen kulttuuriperinnön syntymiseen, periytymiseen ja muutokseen. Kuudennen osan vuonna 2012 voimaan tulleessa asemakaavamuutoksessa suojeltiin 405 rakennusta. Sekä viranomaiset että asukkaat haluavat säilyttää arvokkaan ympäristön jälkipolville. Asukkaiden ja viranomaisten lähtökohdat arvottamiselle ovat kuitenkin erilaiset. Asiantuntijoiden näkemys kulttuuriympäristön arvoista perustuu eksplisiittiseen viralliseen tietoon, joka heijastaa positivistista käsitystä maailmasta mitattavista objekteista koostuvana kokonaisuutena. Asukkaiden arvostus asuinaluetta ja sen rakennuksia kohtaan puolestaan nousee sukupolvelta toiselle siirretyn aineettoman perinnön yhteisöllisestä merkityksestä. Heidän kokemuksensa kiteytyy kodin ja kotiseudun käsitteissä ja se tuodaan esiin rakennuksiin liittyvissä tarinoissa. Tulkinta on virallista tietoa haastavaa ja täydentävää. Kestäviä suojelupäätöksiä voidaan tehdä vain viranomaisten ja asukkaiden väliseen tasa-arvoiseen vuoropuheluun perustuen. Tutkimus nostaa asukkaiden kokemuksellisen, paikkaan sitoutuneen hiljaisen tiedon virallisen tiedon rinnalle, kulttuurisesti kestävän maankäytön suunnittelun perustaksi. Koska ihminen toimii sellaisten asioiden puolesta, jotka hän kokee arvokkaaksi, asukaslähtöinen rakennussuojelu on lähtökohtaisesti yhteisön omakseen kokeman aineettoman kulttuuriperinnön suojelua.

Characterisation of Cladonia rangiferina transcriptome and genome, and the effects of dehydration and rehydration on its gene expression

Lichens are symbiotic organisms, which consist of the fungal partner and the photosynthetic partner, which can be either an alga or a cyanobacterium. In some lichen species the symbiosis is tripartite, where the relationship includes both an alga and a cyanobacterium alongside the primary symbiont, fungus. The lichen symbiosis is an evolutionarily old adaptation to life on land and many extant fungal species have evolved from lichenised ancestors. Lichens inhabit a wide range of habitats and are capable of living in harsh environments and on nutrient poor substrates, such as bare rocks, often enduring frequent cycles of drying and wetting. Most lichen species are desiccation tolerant, and they can survive long periods of dehydration, but can rapidly resume photosynthesis upon rehydration. The molecular mechanisms behind lichen desiccation tolerance are still largely uncharacterised and little information is available for any lichen species at the genomic or transcriptomic level. The emergence of the high-throughput next generation sequencing (NGS) technologies and the subsequent decrease in the cost of sequencing new genomes and transcriptomes has enabled non-model organism research on the whole genome level. In this doctoral work the transcriptome and genome of the grey reindeer lichen, Cladonia rangiferina, were sequenced, de novo assembled and characterised using NGS and traditional expressed sequence tag (EST) technologies. RNA extraction methods were optimised to improve the yield and quality of RNA extracted from lichen tissue. The effects of rehydration and desiccation on C. rangiferina gene expression on whole transcriptome level were studied and the most differentially expressed genes were identified. The secondary metabolites present in C. rangiferina decreased the quality – integrity, optical characteristics and utility for sensitive molecular biological applications – of the extracted RNA requiring an optimised RNA extraction method for isolating sufficient quantities of high-quality RNA from lichen tissue in a time- and cost-efficient manner. The de novo assembly of the transcriptome of C. rangiferina was used to produce a set of contiguous unigene sequences that were used to investigate the biological functions and pathways active in a hydrated lichen thallus. The de novo assembly of the genome yielded an assembly containing mostly genes derived from the fungal partner. The assembly was of sufficient quality, in size similar to other lichen-forming fungal genomes and included most of the core eukaryotic genes. Differences in gene expression were detected in all studied stages of desiccation and rehydration, but the largest changes occurred during the early stages of rehydration. The most differentially expressed genes did not have any annotations, making them potentially lichen-specific genes, but several genes known to participate in environmental stress tolerance in other organisms were also identified as differentially expressed.

From semi-stagnation to growth in a sino-centric market

According to recent available information, the Brazilian economy may be entering a cycle of sustained growth. The dominant current interpretation points to the progresses made in terms of monetary stability, Balance of Payments and structural reforms. Indeed, without monetary stability and the commercial opening of the economy, investments would not be increasing and credit growth would not be helping the emergence of millions of new consumers. But these achievements should be taken as generally conditioning, rather than actually shaping the new picture. Some unexpected (not rarely positive) consequences of overcoming the long enduring semi-stagnation, the emergence of China as a major player, and its consequences on the necessary re-structuring of the Brazilian industry, seem to be decisive in the present day redefinition of the Brazilian GDP growth potential.

Personality traits and personal values : an investigation into the importance of each in the prediction of behaviour /

Personality traits and personal values are two important domains of individual differences. Traits are enduring and distinguishable patterns of behaviour whereas values are societally taught, stable, individual preferences that guide behaviour in order to reach a specific end state. The purpose of the present study was to investigate the relations between self and peer report within the domains of personality traits and values, to examine the correlations between values and traits, and to explore the amount of incremental validity of traits and values in predicting behaviour. Two hundred and fiftytwo men and women from a university setting completed self and peer reports on three questionnaires. In order to assess personality traits, the HEXACO-PI (Lee & Ashton, 2004) was used to identify levels of 6 major dimensions of personality in participants. To assess values, the Schwartz Value Survey (Schwartz, 1992) was used to identify the importance each participant placed on each of Schwartz's 10 value types. To measure behaviour, a Behavior Scale, created by Bardi and Schwartz (2003), consisting of items designed to measure the frequency of value-expressive behaviour was used. As expected, correlations between self and peer reports for the personality scales were high indicating that personality traits are easily observable to other people. Correlations between self and peer reports for the values and behaviour scales were only moderate, suggesting that some goals, and behaviours expressive of those goals, may not always be observable to others. Consistent with previous research, there were many strong correlations between traits and values. In addition to the similarities with past research, the present study found that the personality factor Honesty-Humility was correlated strongly with values scales (with five correlations exceeding .25). In the prediction of behaviour, it was found that both personahty and values were able to account for significant and similar amounts of variance. Personality outpredicted values for some behaviours, but the opposite was true of other behaviours. Each domain provided incremental validity beyond the other domain. The impUcations for these findings, along with limitations, and possibilities for future research are also discussed.

Exploring the experience of the pioneers of change

The world of work with Western society appears to be undergoing a major change. The literature has described this phenomenon as a change from an industrialbased economy to a knowledge-based economy. This change will represent a complete transformation of the world of work; some suggest that everything we have come to accept and know as normal will change. Our present society seems to be in a period of transition. It is a time with many challenges and problems, many of which cannot be solved with thinking patterns from an old industrial-based economy. A fundamental shift in thinking patterns consistent with a new emerging world of work must take place. This change in thinking represents a fundmental shift from traditional and linear ways of seeing the world (worldview), to more holistic ways of seeing the world. In this investigation the word paradigm was used to define how people see their world. A paradigm shift is defined as a change in how a person sees their world: a change from an old to new or different way of viewing the world. Those individuals who are the first to shift their paradigm are called paradigm pioneers. These individuals do not only shift their ways of seeing the world, but they also begin to act and behave in ways consistent with the new paradigm. Thus far the research literature has adequately described the concepts of paradigms and paradigm shifts. However, little is known regarding how people actually and eventually make a shift. As it will be important for each individual to make a personal paradigm shift, then it will be extremely valuable to learn more about the process itself. The purpose of this investigation was to explore these issues in more detail and specifically, describe the experience of paradigm shifts and explore the experience of paradigm pioneers. A qualitative research methodology involving in-depth interviews was used to investigate the experiences of four participants identified as paradigm pioneers. It is interesting to note that the participants in this study did not describe an allencompassing paradigm shift. In fact, each participant, defined a paradigm shift in several different ways. They did relate several examples of paradigm shifts. However, even among these examples, there was a high degree of variability. The findings of this investigation centered upon the participants' experience as pioneers. Each pioneer shared many of the same qualities, the first quality of which described how these pioneers dealt with change. I called this a change-sense quality. The pioneers viewed change in an open and positive manner, and were also aware of change taking place in their world. Finally, they displayed an understanding of change, and a bias to take positive action in the face it. The participants also shared an inner quality. The four pioneers demonstrated a personal purpose and vision, and were selfdirected individuals. They also had an innate curiosity which translated into a love of learning. They also displayed a quality where relationships with others were highly valued. Relationships were important to the pioneers because they played a support role to help them deal with the challenges of being a pioneer. Pioneers also valued relationships because, they relied on others to make change happen. The above mentioned qualities enabled pioneers to be effective in a changing world of work. The findings from this investigation have many implications for research and practice. First, the concept of paradigms and paradigm shifts must be further researched. A great deal more must be learned in order to better understand the kind of shift individuals must make to be effective in the new world of work. Second, the qualities displayed by pioneers are important for all members of the world of work to develop. The qualities shared by pioneers appeared to represent an enduring set of traits that can possibly help individuals deal more positively with uncertainty and rapid change taking place in today's North American world of work.

Ten years after : a qualitative study of students' experiences in a high school theatre company

This qualitative study explored 4 former students' perceptions of the learning associated with their involvement in a high school theatre program and the contextual factors they linked to their perceived development. The study involved 4 adult participants, 2 male and 2 female, who had participated extensively in a high school theatre company from 1996 to 2001 when they were students in a large Ontario school board. Data were collected from January to August, 2007, when the 4 former students took part in two in-depth, open-ended interviews. The focus of investigation was participant perspectives. Data analysis revealed that the 4 participants' involvement in high school theatre produced both wide-ranging and enduring developmental benefits across personal, social, and cognitive domains. Participants achieved these benefits through interactions among 3 related contexts: (a) rehearsal and performance practices, (b) the world of the play, and (c) characteristics of the high school theatre company.
