Samarbete mellan konkurrenter - en undersökning av österbottniska sm-företag

Under senare tid har förekomsten av samarbete mellan konkurrerande sm-företag ökat. Forskningen kring ämnet har dock bedrivits i mindre skala, framför allt om man beaktar finländska (nordiska) förhållanden. Syftet med denna undersökning är att kartlägga förekomsten av samarbete mellan konkurrerande sm-företag i Österbotten (Finland), samt beskriva dessa. Gällande demografiska variabler jämförs dessa företag även med sm-företag som inte samarbetar. Data insamlades genom en enkät utskickad i november 2001 till 345 sm-företag i Österbotten. Svarsprocenten var 35.1. Av de respondenter som besvarade enkäten, var 47.9 procent involverade i ett eller flera samarbeten med ett eller flera företag som var deras konkurrenter. Samarbete mellan konkurrenter är således inte ett ovanligt fenomen, utan innefattar allt från informella, operativa samarbeten till formella, strategiskt viktiga samarbeten. Samarbete inom produktion var den mest vanligt förekommande formen av samarbete. Partnern kom från Finland, även om målmarknaderna för samarbetet fanns både i Finland och i utlandet. Denna undersökning kunde inte identifiera någon större skillnad mellan de sm-företag som samarbetade med konkurrenter och de sm-företag som inte samarbetade. Det intressanta är således att det inte verkar finnas några skillnader vad gäller ålder, omsättning, omsättningsökning, underleverans- och exportverksamhet mellan de samarbetande och de icke samarbetande företagen. Skillnaderna bör således sökas i andra variabler. Den enda signifikanta skillnaden kunde upptäckas i upplevelsen av konkurrens. Tidigare forskning har identifierat att osäkerhet i konkurrensen är ett incitament till att börja samarbeta med konkurrenter. Denna undersökning förstärker detta antagande. De samarbetande företagen upplevde att konkurrensen var hårdare än de icke samarbetande företagen. Bland de samarbetande företagen var det speciellt de mindre (med en personalstyrka mellan 10 och 50 arbetstagare) som upplevde att konkurrensen var hård. Undersökningen har finansierats med stipendiemedel från Sparbanksstiftelsen i Vasa och Handlande Gustav Svanljungs fond.

Protein Kinase C and Anaplastic Lymphoma Kinase Targeted Compounds

The protein kinases (PKs) belong to the largest single family of enzymes, phosphotransferases, which catalyze the phosphorylation of other enzymes and proteins and function primarily in signal transduction. Consequently, PKs regulate cell mechanisms such as growth, differentiation, and proliferation. Dysfunction of these cellular mechanisms may lead to cancer, a major predicament in health care. Even though there is a range of clinically available cancer-fighting drugs, increasing number of cancer cases and setbacks such as drug resistance, constantly keep cancer research active. At the commencement of this study an isophthalic acid derivative had been suggested to bind to the regulatory domain of protein kinase C (PKC). In order to investigate the biological effects and structure-activity relationships (SARs) of this new chemical entity, a library of compounds was synthesized. The best compounds induced apoptosis in human leukemia HL-60 cells and were not cytotoxic in Swiss 3T3 fibroblasts. In addition, the best apoptosis inducers were neither cytotoxic nor mutagenic. Furthermore, results from binding affinity assays of PKC isoforms revealed the pharmacophores of these isophthalic acid derivatives. The best inhibition constants of the tested compounds were measured to 210 nM for PKCα and to 530 nM for PKCδ. Among natural compounds targeting the regulatory domain of PKC, the target of bistramide A has been a matter of debate. It was initially found to activate PKCδ; however, actin was recently reported as the main target. In order to clarify and to further study the biological effects of bistramide A, the total syntheses of the natural compound and two isomers were performed. Biological assays of the compounds revealed accumulation of 4n polyploid cells as the primary mode of action and the compounds showed similar overall antiproliferative activities. However, each compound showed a distinct distribution of antimitotic effect presumably via actin binding, proapoptotic effect presumably via PKCδ, and pro-differentiation effect as evidenced by CD11b expression. Furthermore, it was shown that the antimitotic and proapoptotic effects of bistramide A were not secondary effects of actin binding but independent effects. The third aim in this study was to synthesize a library of a new class of urea-based type II inhibitors targeted at the kinase domain of anaplastic lymphoma kinase (ALK). The best compounds in this library showed IC50 values as low as 390 nM for ALK while the initial low cellular activities were successfully increased even by more than 70 times for NPM-ALK- positive BaF3 cells. More importantly, selective antiproliferative activity on ALK-positive cell lines was achieved; while the best compound affected the BaF3 and SU-DHL-1 cells with IC50 values of 0.5 and 0.8 μM, respectively, they were less toxic to the NPM-ALK-negative human leukemic cells U937 (IC50 = 3.2 μM) and BaF3 parental cells (IC50 = 5.4 μM). Furthermore, SAR studies of the synthesized compounds revealed functional groups and positions of the scaffold, which enhanced the enzymatic and cellular activities.

Phylogeography unplugged: comparative surveys in the genomic era

In March 2012, the authors met at the National Evolutionary Synthesis Center (NESCent) in Durham, North Carolina, USA, to discuss approaches and cooperative ventures in Indo-Pacific phylogeography. The group emerged with a series of findings: (1) Marine population structure is complex, but single locus mtDNA studies continue to provide powerful first assessment of phylogeographic patterns. (2) These patterns gain greater significance/power when resolved in a diversity of taxa. New analytical tools are emerging to address these analyses with multi-taxon approaches. (3) Genome-wide analyses are warranted if selection is indicated by surveys of standard markers. Such indicators can include discordance between genetic loci, or between genetic loci and morphology. Phylogeographic information provides a valuable context for studies of selection and adaptation. (4) Phylogeographic inferences are greatly enhanced by an understanding of the biology and ecology of study organisms. (5) Thorough, range-wide sampling of taxa is the foundation for robust phylogeographic inference. (6) Congruent geographic and taxonomic sampling by the Indo-Pacific community of scientists would facilitate better comparative analyses. The group concluded that at this stage of technology and software development, judicious rather than wholesale application of genomics appears to be the most robust course for marine phylogeographic studies. Therefore, our group intends to affirm the value of traditional (''unplugged'') approaches, such as those based on mtDNA sequencing and microsatellites, along with essential field studies, in an era with increasing emphasis on genomic approaches.

A Method for siting and prioritizing the removal of derelict vessels in Florida Coastal Waters: test applications in the Florida Keys

Increased boating activities and new waterfront developments have contributed an estimated 3,000 dismantled, abandoned, junked, wrecked, derelict vessels to Florida coastal waters. This report outlines a method of siting and prioritizing derelict vessel removal using the Florida Keys as a test area. The data base was information on 240 vessels, obtained from Florida Marine Patrol files. Vessel location was plotted on 1:250,000 regional and 1:5,000 and 1:12,000 site maps. Type of vessel, length, hull material, engine, fuel tanks, overall condition, afloat and submerged characteristics, and accessibility, were used to derive parametric site indices of removal priority and removal difficulty. Results indicate 59 top priority cases which should be the focus of immediate clean up efforts in the Florida Keys. Half of these cases are rated low to moderate in removal difficulty; the remainder are difficult to remove. Removal difficulty is a surrogate for removal cost: low difficulty -low cost, high difficulty - high cost. The rating scheme offers coastal planners options of focusing removal operations either on (1) specific areas with clusters of high priority derelict vessels or on (2) selected targeted derelicts at various, specific locations.

O laboratório analítico: a psicologia de C.G. Jung examinada pela teoria do ator-rede

O psiquiatra suíço Carl Gustav Jung (1875-1961) é um dos principais nomes da psicologia e da psicoterapia do século XX. Algumas de suas maiores contribuições teórico-metodológicas são as idéias de realidade psíquica, complexo, arquétipo (inconsciente coletivo), processo de individuação, método dialético, método construtivo e imaginação ativa. A psicologia analítica de Jung, ao longo de sua formação, foi influenciada por diversas disciplinas, dentre elas a etnologia (ciências sociais). Este trabalho buscou dar continuidade a este processo de construção epistêmica, mediante exame das concepções de Jung por intermédio da teoria do ator-rede (TAR), uma importante corrente da sociologia contemporânea. Pretendeu-se também saber se a psicologia analítica se mantém atual ou se já é uma teoria e prática clínica anacrônicas. O principal autor relacionado à TAR a quem se recorreu neste trabalho foi o sociólogo francês Bruno Latour. De sua perspectiva, o acordo moderno, disjuntor de Natureza e Cultura, é insuficiente para explicar a complicação inerente às entidades que compõem a realidade. Para escapar das armadilhas conceptuais da modernidade, Latour opera com constructos tais como coletivo (social), ator-rede, proposição, vínculo e plasma. Além do pensamento de Latour, este trabalho valeu-se das idéias sociológicas de Gabriel Tarde e da influenciologia etnopsicanalítica de Tobie Nathan, aproveitando-se da afinidade teórica que compartilham com Latour. Nathan, por desenvolver uma prática em psicoterapia, permitiu propor à psicologia clínica de Jung determinadas questões que o enfoque mais estritamente sociológico de Latour não possibilitava. Uma vez expostas as concepções de Latour, Tarde e Nathan, apresentaram-se os elementos da psicologia analítica com os quais se esperava que elas fossem compatíveis. Concluiu-se que, apesar das diferenças, muitas aproximações são plausíveis entre psicologia analítica e TAR. Constatou-se que a concepção de Jung de um psiquismo multifacetado, em devir, cujos componentes se relacionam de diferentes maneiras, é comparável à noção de ator-rede trabalhada por Latour e à monadologia de Tarde. Verificou-se também que a abordagem pragmática e construtiva identificada na psicoterapia junguiana é em muitos aspectos análoga à prática da etnopsicanálise. Assim, foi possível afirmar que a TAR e a psicologia analítica podem formar aliança.

A vida do artista e a crise da modernidade: uma leitura de Morte em Veneza, de Thomas Mann

Este trabalho busca compreender os problemas enfrentados pelo artista burguês para o cultivo de sua alma sem diante do problema da crise da modernidade. Entre os séculos XIX e XX a autonomização do mundo e a fragmentação da cultura em duas esferas distintas objetiva e subjetiva tornaram a vida cotidiana uma perspectiva problemática para aqueles que desejavam atingir um nível elevado de suas almas. Nesse sentido, a obra Morte em Veneza (1912) de Thomas Mann conta a história de um artista Gustav Aschenbach que rejeita o mundo e seus sentimentos no intuito de explorar um ideal estético clássico e impossível de se articular com a realidade. A história narra a trajetória desse artista do momento em que decide deixar a Alemanha, seu país natal, rumo à Veneza, no intuito de recuperar-se da exaustão que o exercício do trabalho vocacionado lhe impõe. Mostraremos que Veneza assume, sob tal perspectiva, um papel de grande relevância, pois se relaciona de maneira direta ao ideal de vida do artista. E será em Veneza que Aschenbach encontrará na figura de um garoto a manifestação real de seus anseios idealísticos do belo. Tal encontro produzirá, no artista, um descontrole e uma anarquia de sentimentos que o levará diretamente ao abismo.

Benthic habitats of Fish Bay, Coral Bay and the St. Thomas East End Reserve

NOAA’s National Centers for Coastal Ocean Science Biogeography Branch has mapped and characterized large portions of the coral reef ecosystems inside the U.S. coastal and territorial waters, including the U.S. Caribbean. The complementary protocols used in these efforts have enabled scientists and managers to quantitatively and qualitatively compare marine ecosystems in tropical U.S. waters. The Biogeography Branch used similar protocols to generate new benthic habitat maps for Fish Bay, Coral Bay and the St. Thomas East End Reserve (STEER). While this mapping effort marks the third time that some of these shallow-water habitats (≤40 m) have been mapped, it is the first time that nearly 100% of the seafloor has been characterized in each of these areas. It is also the first time that high resolution imagery describing seafloor depth has been collected in each of these areas. Consequently, these datasets provide new information describing the distribution of coral reef ecosystems and serve as a spatial baseline for monitoring change in the Fish Bay, Coral Bay and the STEER. Benthic habitat maps were developed for approximately 64.3 square kilometers of seafloor in and around Fish Bay, Coral Bay and the STEER. Twenty seven percent (17.5 square kilometers) of these habitat maps describe the seafloor inside the boundaries of the STEER, the Virgin Islands National Park and the Virgin Islands Coral Reef National Monument. The remaining 73% (46.8 square kilometers) describe the seafloor outside of these MPA boundaries. These habitat maps were developed using a combination of semi-automated and manual classification methods. Habitats were interpreted from aerial photographs and LiDAR (Light Detection and Ranging) imagery. In total, 155 distinct combinations of habitat classes describing the geology and biology of the seafloor were identified from the source imagery.
