Speech acts, responsibility and commitment in poetry

Philosophy has tended to regard poetry primarily in terms of truth and falsity, assuming that its business is to state or describe states of affairs. Speech act theory transforms philosophical debate by regarding poetry in terms of action, showing that its business is primarily to do things. The proposal can sharpen our understanding of types of poetry; examples of the ‘Chaucer-Type’ and its variants demonstrate this. Objections to the proposal can be divided into those that relate to the agent of actions associated with a poem, those that relate to the actions themselves, and those that relate to the things done. These objections can be answered. A significant consequence of the proposal is that it gives prominence to issues of responsibility and commitment. This prominence brings philosophical debate usefully into line with contemporary poetry, whose concern with such issues is manifest in characteristic forms of anxiety.

Time to act: the UK in NATO

Since 1989, NATO has expanded its strategic concept and geopolitical scope to the detriment of an efficient and well-defined military capability in Europe. The Ukrainian crisis has brought the attention back to Europe and to NATO’s deterrent value. As one of the Alliance’s leading members, Britain must act as a catalyst to ensure that NATO has the necessary military strength and political will to respond to the new security challenges.

Processes of feelings in a society with a violent past : A qualitative study of the communication for Societal healing in the Truth Commissions in East Timor, Sri Lanka and Ghana between 2002-2011

The research investigates in what extent and how communication for meeting feelings is provided in Truth Commission work. It examines if and in what way feelings are addressed in the communication officially published by the Truth Commissions in East Timor, Ghana and Sri Lanka, occurring between 2002-2011. The research is also looking at the healing processes in a time perspective to find out if there is a communication for Societal healing to be continued in a longer term. My conclusion is that two cases of three in my research, the TRCs in Ghana and East Timor, have communication clearly directed to meet feelings caused by the war. One of the three cases (East Timor) has a communication with a clear ambition to heal over a longer period, to continue after the existence of the Truth Commission. The research suggests that communication with a clear ambition to reach out widely in the society, a communication directed to meet and process feelings over a longer period, can make Societal healing more effective. It also concludes that, in the future, Societal healing, as a field in conflict resolution, will be more based on representational media than today, provided through web communication.

Dip financing of financially distressed companies in Brazil – the conditions provided by the brazilian bankruptcy law act as real incentives for dip lenders as in chapter 11 of the American bankruptcy code?

O objeto deste trabalho é a compreensão do financiamento de empresas em crise, mais especificamente, o financiamento concedido após o pedido de recuperação judicial, como forma de permitir que a empresa saia da situação de crise e retorne à condição de normalidade. Para tanto, nos apropriando do termo cunhado pela doutrina norte-americana, para fazer referência ao aporte de recursos em empresas em dificuldade, utilizaremos o termo DIP financing ou financiamento DIP. Para uma compreensão adequada do objeto, é necessário que entendamos a origem do DIP financing nos Estados Unidos e como é a regulação norte-americana sobre a matéria atualmente. O segundo passo será avaliar a possibilidade de aplicação da mesma estrutura de aporte de recursos no Brasil. Ao estudarmos a origem desse mecanismo nos Estados Unidos, veremos os problemas que surgiram ao longo dos anos e como foram superados jurisprudencialmente e doutrinariamente para que o financiamento DIP se consolidasse como uma das formas de aporte de capital em empresas em crise, culminando no desenvolvimento de uma verdadeira indústria de crédito às empresas em dificuldade. Uma análise dos problemas enfrentados pelo sistema falimentar americano nos levará a hipótese de que, a menos que sejam afirmados mecanismos que assegurem a quem concede o financiamento após o pedido de recuperação judicial, uma super prioridade no recebimento após a recuperação judicial, será possível o desenvolvimento de um mercado de DIP financing no Brasil.

Cyclicality of SME Lending and Government Involvement in Banks

Recent regulatory efforts aim at lowering the cyclicality of bank lending because of its potential detrimental effects on financial stability and the real economy. We investigate the cyclicality of SME lending by local banks with vs. without a public mandate, controlling for location, size, loan maturity, funding structure, liquidity, profitability, and credit demand-side factors. The public mandate is set by local governments and stipulates a deviation from strict profit maximization and a sustainable provision of financial services to local customers. We find that banks with a public mandate are 25 percent less cyclical than other local banks. The result is credit supply-side driven and especially strong for savings banks with high liquidity and stable deposit funding. Our findings have implications for the banking structure, financial stability and the finance-growth nexus in a local context.

Peer to peer lending and financial inclusion in Brazil: a case study

While pursuing the objective to investigate the potential for the P2P innovation to enhance financial inclusion in Brazil, the P2P industry and the current market environment were analyzed in order to highlight the factors that can facilitate this desired enhancement. There seems to be no doubt that there is substantial potential for the P2P industry worldwide and in Brazil but, beyond this, a considerable part of this industry could be providing financially inclusive products. The P2P industry in Brazil needs to recognize the potential for growing, not only the industry itself, but also the market for financially inclusive P2P products. The first section of this thesis focuses on financial inclusion briefly in order to establish the frame of what is being addressed. Subsequently the P2P industry is analyzed globally, locally in Brazil and with regard to financial inclusion. The study is conducted through an interview with the founder of a P2P platform in Brazil and its data collection is used to build a case study which allowed for an analysis of the potential for financial inclusion of the P2P industry and the development of key success factors with regard to converting this potential into results.

Can sieve-element plastids in Panicum maximum (Poaceae) leaves act in the blockage of injured sieve-tube elements?

The ultrastructural features and the plastid changes caused by sample preparation were studied in sieve elements of Panicum maximum leaves. Samples of expanded leaves, taken near the ligule region, were fixed and processed by common light and transmission electron microscopy methods. In mature sieve-tube elements, the protoplast is electron-translucent and plastids are the most frequent organelles. Mitochondria and smooth endoplasmic reticulum segments are also visible and occupy a parietal position within the cell. The plastids are globular and show electron-dense proteinaceous inclusions in the stroma. The protein crystals are predominantly cuneate, but thin crystalloids and amorphous and/or filamentous proteins also occur. The presence of intact plastids plus others in different phases of plastid envelope rupture were interpreted as evidence that this rupture is a normal event in response to injury. This plastid envelope rupture is possibly activated by the release of pressure in the sieve-tube element. After plastid membrane vesiculation, the stroma and the protein crystals are dispersed within the sieve-element ground cytoplasm. The vesicles originating from the plastid envelope move to one cell pole, while protein crystalloids move to the opposite pole and agglomerate in the sieve-plate region. Our findings indicate that these protein crystalloids, which deposit in the sieve plate, may act in sieve-plate pores occlusion, preventing the release of phloem sap, similar to the role of P-protein in dicotyledons.

Leaf glands act as nectaries in Diplopterys pubipetala (Malpighiaceae)

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)

Do Terrestrial Tank Bromeliads in Brazil Create Safe Sites for Palm Establishment or Act as Natural Traps for Its Dispersed Seeds ?

This study shows for the first time that terrestrial tank bromeliads from Brazilian restinga can act as natural traps for dispersed palm Euterpe edulis seeds. Such bromeliads, which are shade intolerant, gain benefits by limiting palm recruitment since they hinder canopy formation and, consequently, increase luminosity over its aggregates.

Progesterone restores the female prostate activity in ovariectomized gerbil and may act as competitor of testosterone in intraprostatic environment

Aims Little is known about the effect of progesterone on gerbil female prostate. It is known that normal oscillation in the progesterone and estradiol levels during the estrous cycle phases influence the morphophysiology of this gland. The present study aims to evaluate the isolated effect of prolonged administration of progesterone combined or not with testosterone on the prostate of ovariectomized female gerbil. Main methods To observe the morphological changes caused by castration in the prostate of different groups stereologic analyses of all prostate compartments, analysis of nuclear area and perimeter, and morphometric measurements of epithelial and smooth muscle cells layers were used. In addition, immunocytochemistry was performed to investigate the distribution of the androgen, estrogen alfa and beta and progesterone receptors in different prostatic compartments. Key findings This study demonstrated that both treatments partially recovered the structure of the gland. In the group treated with progesterone plus testosterone a higher incidence of epithelial and stromal disorders occurred, besides the absence of secretory activity. Thus, treatment only with progesterone showed better results in the restoration of glandular homeostasis mainly seen by the regulation of the secretory activity. Significance Collectively, the findings of this study indicate that progesterone may have a significant role on the maintenance of prostate morphophysiology, and showed an interesting evidence of hormonal competition between progesterone and testosterone. © 2013 Elsevier Inc.

Ferroelectric and structural instability of (Pb,Ca)TiO3 thin films prepared in an oxygen atmosphere and deposited on LSCO thin films which act as a buffer layer

Structural, microstructural and ferroelectric properties of Pb0.90Ca0.10TiO3 (PCT10) thin films deposited using La0.50Sr0.50CoO3 (LSCO) thin films which serve only as a buffer layer were compared with properties of the thin films grown using a platinum-coated silicon substrate. LSCO and PCT10 thin films were grown using the chemical solution deposition method and heat-treated in an oxygen atmosphere at 700 °C and 650 °C in a tube oven, respectively. X-ray diffraction (XRD) and Raman spectroscopy results showed that PCT10 thin films deposited directly on a platinum-coated silicon substrate exhibit a strong tetragonal character while thin films with the LSCO buffer layer displayed a smaller tetragonal character. Surface morphology observations by atomic force microscopy (AFM) revealed that PCT10 thin films with a LSCO buffer layer had a smoother surface and smaller grain size compared with thin films grown on a platinum-coated silicon substrate. Additionally, the capacitance versus voltage curves and hysteresis loop measurement indicated that the degree of polarization decreased for PCT10 thin films on a LSCO buffer layer compared with PCT10 thin films deposited directly on a platinum-coated silicon substrate. This phenomenon can be described as the smaller shift off-center of Ti atoms along the c-direction 〈001〉 inside the TiO6 octahedron unit due to the reduction of lattice parameters. Remnant polarization (P r ) values are about 30 μC/cm2 and 12 μC/cm2 for PCT10/Pt and PCT10/LSCO thin films, respectively. Results showed that the LSCO buffer layer strongly influenced the structural, microstructural and ferroelectric properties of PCT10 thin films. © 2013 Elsevier Ltd and Techna Group S.r.l.

Green tea polyphenol epigallocatechin-3-gallate and cranberry proanthocyanidins act in synergy with cathelicidin (LL-37) to reduce the LPS-induced inflammatory response in a three-dimensional co-culture model of gingival epithelial cells and fibroblasts

Objectives: The human antimicrobial peptide cathelicidin (LL-37) possesses anti-inflammatory properties that may contribute to attenuating the inflammatory process associated with chronic periodontitis. Plant polyphenols, including those from cranberry and green tea, have been reported to reduce inflammatory cytokine secretion by host cells. In the present study, we hypothesized that A-type cranberry proanthocyanidins (AC-PACs) and green tea epigallocatechin-3-gallate (EGCG) act in synergy with LL-37 to reduce the secretion of inflammatory mediators by oral mucosal cells. Methods: A three-dimensional (3D) co-culture model of gingival epithelial cells and fibroblasts treated with non-cytotoxic concentrations of AC-PACs (25 and 50 mg/ml), EGCG (1 and 5 mg/ml), and LL-37 (0.1 and 0.2 mM) individually and in combination (AC-PACs + LL-37 and EGCG + LL-37) were stimulated with Aggregatibacter actinomycetemcomitans lipopolysaccharide (LPS). Multiplex ELISA assays were used to quantify the secretion of 54 host factors, including chemokines, cytokines, growth factors, matrix metalloproteinases (MMPs), and tissue inhibitors of metalloproteinases (TIMPs). Results: LL-37, AC-PACs, and EGCG, individually or in combination, had no effect on the regulation of MMP and TIMP secretion but inhibited the secretion of several cytokines. ACPACs and LL-37 acted in synergy to reduce the secretion of CXC-chemokine ligand 1 (GRO-a), granulocyte colony-stimulating factor (G-CSF), and interleukin-6 (IL-6), and had an additive effect on reducing the secretion of interleukin-8 (IL-8), interferon-g inducible protein 10 (IP-10), and monocyte chemoattractant protein-1 (MCP-1) in response to LPS stimulation. EGCG and LL-37 acted in synergy to reduce the secretion of GRO-a, G-CSF, IL-6, IL-8, and IP-10, and had an additive effect on MCP-1 secretion. Conclusion: The combination of LL-37 and natural polyphenols from cranberry and green tea acted in synergy to reduce the secretion of several cytokines by an LPS-stimulated 3D coculture model of oral mucosal cells. Such combinations show promising results as potential adjunctive therapies for treating inflammatory periodontitis.
