The GA5 locus of Arabidopsis thaliana encodes a multifunctional gibberellin 20-oxidase: molecular cloning and functional expression.

The biosynthesis of gibberellins (GAs) after GA12-aldehyde involves a series of oxidative steps that lead to the formation of bioactive GAs. Previously, a cDNA clone encoding a GA 20-oxidase [gibberellin, 2-oxoglutarate:oxygen oxidoreductase (20-hydroxylating, oxidizing), EC 1.14.11.-] was isolated by immunoscreening a cDNA library from liquid endosperm of pumpkin (Cucurbita maxima L.) with antibodies against partially purified GA 20-oxidase. Here, we report isolation of a genomic clone for GA 20-oxidase from a genomic library of the long-day species Arabidopsis thaliana Heynh., strain Columbia, by using the pumpkin cDNA clone as a heterologous probe. This genomic clone contains a GA 20-oxidase gene that consists of three exons and two introns. The three exons are 1131-bp long and encode 377 amino acid residues. A cDNA clone corresponding to the putative GA 20-oxidase genomic sequence was constructed with the reverse transcription-PCR method, and the identity of the cDNA clone was confirmed by analyzing the capability of the fusion protein expressed in Escherichia coli to convert GA53 to GA44 and GA19 to GA20. The Arabidopsis GA 20-oxidase shares 55% identity and > 80% similarity with the pumpkin GA 20-oxidase at the derived amino acid level. Both GA 20-oxidases share high homology with other 2-oxoglutarate-dependent dioxygenases (2-ODDs), but the highest homology was found between the two GA 20-oxidases. Mapping results indicated tight linkage between the cloned GA 20-oxidase and the GA5 locus of Arabidopsis. The ga5 semidwarf mutant contains a G-->A point mutation that inserts a translational stop codon in the protein-coding sequence, thus confirming that the GA5 locus encodes GA 20-oxidase. Expression of the GA5 gene in Ara-bidopsis leaves was enhanced after plants were transferred from short to long days; it was reduced by GA4 treatment, suggesting end-product repression in the GA biosynthetic pathway.

Perspectivas em exercício: Uma investigação sobre a lógica administrativa e o engajamento subjetivo no trabalho

Esta pesquisa tem como tema os discursos que circulam e estruturam o ambiente de trabalho nas empresas. De forma geral, busca-se compreender a lógica administrativa que, no limite, exerce uma condução da subjetividade dos trabalhadores. Temos por objetivos: 1) identificar como nas escolas do pensamento administrativo do século XX o engajamento do trabalho é requerido dos trabalhadores; 2) pretendemos discutir uma possível caracterização do discurso e dos usos da administração, como campo de conhecimento sobre o trabalho, dentro das organizações. Para tanto, estabelecemos como panorama teórico-metodológico nas ideias centrais de Michel Foucault em suas análises sobre a funcionalidade do poder e seus dispositivos. Propusemos uma perspectiva arqueogenealógica para a estudar o tema trabalho por meio da lógica da administração e do engajamento. Para estruturar esta análise, selecionamos disciplinas oferecidas e examinamos ementas e referências de leituras nos cursos de graduação da Escola de Administração de Empresas de São Paulo da Fundação Getúlio Vargas (EAESP-FGV) e do curso de Administração da Faculdade de Economia, Administração e Contabilidade da Universidade de São Paulo (FEA-USP). Diante do contato com a discursividade administrativa pudemos formular algumas reflexões. A Administração de Empresas é a ciência da demonstração, pautada na dominação da realidade por uma dita eficiência. É o que se faz produtivo da realidade ou o que se produz nela que se torna científico. Não há discussão, nos registros aqui investigados, de um questionamento sobre o discurso de eficiência, de melhores práticas e da localização das organizações como construções historicamente produzidas, apenas como produtoras de determinações. Não parece haver a possibilidade de desnaturalizar a empresa. A administração parece estar pautada em uma duplicação da dominação como a profissão que é moldada ao moldar o trabalho. Partimos também da análise do que se nomeia engajamento para compreender o que é requerido do trabalhador para além do contrato de trabalho e de sua produtividade material. Neste sentido, o trabalho torna-se uma experiência de educação em contínua e ininterrupta vigilância pedagógica. O efeito moral das técnicas e das provas nas correntes de pensamento da administração permite uma condução técnica e do modo de viver dos trabalhadores. Nesse sentido, a administração, propõe o aperfeiçoamento do cuidado de si no trabalho e para o trabalho. As disciplinas então se duplicam: pelo exterior, por meio da regra pautada na estrutura formal da autoridade da fábrica/empresa com o governo dos corpos; e pelo interior por meio de uma sujeição por identidade, pela estilização da vida

Constructing a Neuroscientific Pastoral Theology of Fear and Hope

Contemporary therapeutic circles utilize the concept of anxiety to describe a variety of disorders. Emotional reductionism is a detriment to the therapeutic community and the persons seeking its help. This dissertation proposes that attention to the emotion of fear clarifies our categorization of particular disorders and challenges emotional reductionism. I propose that the emotion of fear, through its theological relationship to hope, is useful in therapeutic practice for persons who experience trauma and PTSD. I explore the differences between fear and anxiety by deconstructing anxiety. Through this process, I develop four categories which help the emotion of fear stand independent of anxiety in therapy. Temporality, behaviors, antidote and objects are categories which distinguish fear from anxiety. Together, they provide the impetus to explore the emotion of fear. Understanding the emotion of fear requires an examination of its neurophysiological embodiment. This includes the brain structures responsible for fear production, its defensive behaviors and the evolutionary retention of fear. Dual inheritance evolutionary theory posits that we evolved physically and culturally, helping us understand the inescapability of fear and the unique threats humans fear. The threats humans react to develop through subjective interpretations of experience. Sometimes threats, through their presence in our memories and imaginations, inhibit a person's ability to live out a preferred identity and experience hope. Understanding fear as embodied and subjective is important. Process theology provides a religious framework through which fear can be interpreted. In this framework, fear is developed as an adaptive human response. Moreover, fear is useful to the divine-human relationship, revealing an undercurrent of hope. In the context of the divine-human relationship fear is understood as an initial aim which protects a person from a threat, but also preserves them for novel future relationships. Utilizing a "double-listening" stance, a therapist hears the traumatic narrative and counternarratives of resistance and resilience. These counternarratives express an orientation towards hopeful futures wherein persons thrive through living out a preferred identity. A therapeutic practice incorporating the emotion of fear will utilize the themes of survival, coping and thriving to enable persons to place their traumatic narrative within their meaning systems.

Involvement of loop 5 lysine residues and the N-terminal β-hairpin of the ribotoxin hirsutellin A on its insecticidal activity

Ribotoxins are cytotoxic members of the family of fungal extracellular ribonucleases best represented by RNase T1. They share a high degree of sequence identity and a common structural fold, including the geometric arrangement of their active sites. However, ribotoxins are larger,with a well-defined N-terminal β-hairpin, and display longer and positively charged unstructured loops. These structural differences account for their cytotoxic properties.Unexpectedly, the discovery of hirsutellin A (HtA), a ribotoxin produced by the invertebrate pathogen Hirsutella thompsonii, showed how it was possible to accommodate these features into a shorter amino acid sequence. Examination of HtA N-terminal β-hairpin reveals differences in terms of length, charge, and spatial distribution. Consequently,four different HtA mutants were prepared and characterized. One of them was the result of deleting this hairpin [Δ(8-15)] while the other three affected single Lys residues in its close spatial proximity (K115E, K118E, and K123E). The results obtained support the general conclusion that HtA active site would show a high degree of plasticity,being able to accommodate electrostatic and structural changes not suitable for the other previously known larger ribotoxins, as the variants described here only presented small differences in terms of ribonucleolytic activity and cytotoxicity against cultured insect cells.

I'm Not Who I Thought I Was: A Contextual Resolution to the Identity Loss of Combat PTSD.

Given the historical rates of combat post-traumatic stress disorder (PTSD), one can expect 30% of soldiers returning from current military conflicts to suffer from PTSD. For these individuals, various cognitive behavioral therapies (CBT) are the most commonly employed treatments. Unfortunately, however, symptom relapse can be expected with the various CBT approaches, as traumatic memories remain. Soldiers are imbued with a militarized identity, and the identity loss experienced by those soldiers who suffer from PTSD is particularly painful for this population, as the militarized identity effectively disavows personal suffering. For this reason, many combat veterans diagnosed with post-traumatic stress disorder experience undue, prolonged suffering as they struggle to make sense of the different person they fear they have become. This paper contrasts certain versions of Western philosophy, which view the self as a fixed and reified entity with certain versions of Eastern philosophy, which view the self as more contextual and fluid, in order to illuminate the value of employing third wave behavioral treatments, specifically Acceptance and Commitment Therapy (ACT), to treat the identity loss experienced by military veterans with PTSD. ACT echoes the Buddhist principle that attachment to verbally-constructed conceptual notions of self contribute to undue suffering, and that more vital living can be achieved by assuming a more contextual and experiential perspective on identity. Research and anecdotal accounts are cited to illustrate why treatment for identity loss associated with combat PTSD should be less focused on reconstructing a historically substance-oriented self and more focused on an epistemological reorientation to a deconstructed, contextual self.

Symbol for a Community: The Dickens Opera House and Theaters of the American West

This paper reveals the importance of the Dickens Opera House to the local history of Longmont, Colorado. Through an exploration of pioneer history and of architectural patronage and audience accommodation, this paper illustrates how the Dickens Opera House participated in the construction of cultural identity and civic aspirations of the city of Longmont. Using the Tabor Opera House of Leadville and Wright Opera House of Ouray as framing examples to place the Dickens Opera House within its proper architectural and historical context, I approach the building’s inception, construction, and early years as a way to track the early civic identity of a community through a work of architecture. The Dickens Opera House provided a point for the citizens of Longmont to focus their hopes of success and respectability in a newly formed community. An opera house provided a high-class perception of a town that provided a projection of respectability. Such a construction was built from various sources – the architecture of the building, simply calling the building an ‘opera house’, furnishings in the latest fashions and equipment of the latest technology, and extravagant scenery and curtains. In addition to these outward projections, opera houses also provided a place for community events. It was the location in town that brought people together.

Body Percussion and Team Building through the BAPNE Method

BAPNE Method is a method based on cognitive stimulation integrating music and movement through body percussion. The aim of this research is to explore its whole potential as a tool to build teams. Team building is a philosophy for work design, and since over two decades ago, it defends that obtaining a high performance and organizing efficiency is more useful to perceive employees as interdependent members in a team of work than individuals ones. From this viewpoint, this research advocates that BAPNE Method’s body percussion practice will have an impact on this vision of team work directly. For its own characteristics, body percussion stimulates ways of contact in movement, which ease social ties and, especially, promote group cohesion. Through social, body and, affective dimension; BAPNE Method is capable of developing a shared vision and a single aim, to stimulate team work identity and an atmosphere of trust; and finally, to improve individual communication and satisfaction levels in group tasks.

SCAPHOID AND LUNATE CARPAL MECHANICS OVER THE SPECTRUM OF HEALTHY FUNCTION

When ligaments within the wrist are damaged, the resulting loss in range of motion and grip strength can lead to reduced earning potential and restricted ability to perform important activities of daily living. Left untreated, ligament injuries ultimately lead to arthritis and chronic pain. Surgical repair can mitigate these issues but current procedures are often non-anatomic and unable to completely restore the wrist’s complex network of ligaments. An inability to quantitatively assess wrist function clinically, both before and after surgery, limits the ability to assess the response to clinical intervention. Previous work has shown that bones within the wrist move in a similar pattern across people, but these patterns remain challenging to predict and model. In an effort to quantify and further develop the understanding of normal carpal mechanics, we performed two studies using 3D in vivo carpal bone motion analysis techniques. For the first study, we measured wrist laxity and performed CT scans of the wrist to evaluate 3D carpal bone positions. We found that through mid-range radial-ulnar deviation range of motion the scaphoid and lunate primarily flexed and extended; however, there was a significant relationship between wrist laxity and row-column behaviour. We also found that there was a significant relationship between scaphoid flexion and active radial deviation range of motion. For the second study, an analysis was performed on a publicly available database. We evaluated scapholunate relative motion over a full range of wrist positions, and found that there was a significant amount of variation in the location and orientation of the rotation axis between the two bones. Together the findings from the two studies illustrate the complexity and subject specificity of normal carpal mechanics, and should provide insights that can guide the development of anatomical wrist ligament repair surgeries that restore normal function.

Elections to the European Parliament and the trouble with vox populi. EPIN Commentary No. 12, 22 August 2013

Declining support for the European Union in many member states is causing some disquiet about the possibility of an even lower voter turnout in the upcoming European Parliament (EP) elections to be held next May. This discontent might well be exploited by populist anti-European parties and boost protest-vote participation, cautions Sonia Piedrafita in this EPIN Commentary, and this would pose a serious risk for EU decision-making and undermine the sense of common identity and any plans for further integration. This Commentary, which looks at the elections from an EU perspective, is the first in a series of Commentaries by EPIN (European Policy Institutes Network) that will examine the outlook for the European Parliament elections in various member states.

What is happening to the Schengen borders? CEPS Liberty and Security in Europe No. 86, December 2015

What is happening to the Schengen borders? Is Schengen in ‘crisis’? This paper examines the state of play in the Schengen system in light of the developments during 2015. It critically examines the assertion that Schengen is ‘in crisis’ and seeks to set the record straight on what has been happening to the intra-Schengen border-free and common external borders system. The paper argues that Schengen is here to stay and that reports about the reintroduction of internal border checks are exaggerated as they are in full compliance with the EU rule of law model laid down in the Schengen Borders Code and subject to scrutiny by the European Commission. It also examines the legal challenges inherent to police checks within the internal border areas as having an equivalent effect to border checks as well as the newly adopted proposal for a European Border and Coast Guard system. The analysis shows that the most far-reaching challenge to the current and future configurations of EU border policies relates to ensuring that they are in full compliance with fundamental human rights obligations to refugees, effective accountability and independent monitoring of the implementation of EU legal standards. This should be accompanied by a transparent and informed discussion on which ‘Schengen’ and which 'common European Border and Coast Guard Agency' we exactly want within current democratic rule of law and fundamental rights remits.
