Regional representativity of AERONET observation sites during the biomass burning season in South America determined by correlation studies with MODIS Aerosol Optical Depth

This paper presents an analysis of ground-based Aerosol Optical Depth (AOD) observations by the Aerosol Robotic Network (AERONET) in South America from 2001 to 2007 in comparison with the satellite AOD product of Moderate Resolution Imaging Spectroradiometer (MODIS), aboard TERRA and AQUA satellites. Data of 12 observation sites were used with primary interest in AERONET sites located in or downwind of areas with high biomass burning activity and with measurements available for the full time range. Fires cause the predominant carbonaceous aerosol emission signal during the dry season in South America and are therefore a special focus of this study. Interannual and seasonal behavior of the observed AOD at different sites were investigated, showing clear differences between purely fire and urban influenced sites. An intercomparison of AERONET and MODIS AOD annual correlations revealed that neither an interannual long-term trend may be observed nor that correlations differ significantly owing to different overpass times of TERRA and AQUA. Individual anisotropic representativity areas for each AERONET site were derived by correlating daily AOD of each site for all years with available individual MODIS AOD pixels gridded to 1 degrees x 1 degrees. Results showed that for many sites a good AOD correlation (R(2) > 0.5) persists for large, often strongly anisotropic, areas. The climatological areas of common regional aerosol regimes often extend over several hundreds of kilometers, sometimes far across national boundaries. As a practical application, these strongly inhomogeneous and anisotropic areas of influence are being implemented in the tropospheric aerosol data assimilation system of the Coupled Chemistry-Aerosol-Tracer Transport Model coupled to the Brazilian Regional Atmospheric Modeling System (CCATT-BRAMS) at the Brazilian National Institute for Space Research (INPE). This new information promises an improved exploitation of local site sampling and, thus, chemical weather forecast.

Cell-cell signal-dependent dynamic interactions between HD-GYP and GGDEF domain proteins mediate virulence in Xanthomonas campestris

RpfG is a paradigm for a class of widespread bacterial two-component regulators with a CheY-like receiver domain attached to a histidine-aspartic acid-glycine-tyrosine-proline (HD-GYP) cyclic di-GMP phosphodiesterase domain. In the plant pathogen Xanthomonas campestris pv. campestris (Xcc), a two-component system comprising RpfG and the complex sensor kinase RpfC is implicated in sensing and responding to the diffusible signaling factor (DSF), which is essential for cell-cell signaling. RpfF is involved in synthesizing DSF, and mutations of rpfF, rpfG, or rpfC lead to a coordinate reduction in the synthesis of virulence factors such as extracellular enzymes, biofilm structure, and motility. Using yeast two-hybrid analysis and fluorescence resonance energy transfer experiments in Xcc, we show that the physical interaction of RpfG with two proteins with diguanylate cyclase (GGDEF) domains controls a subset of RpfG-regulated virulence functions. RpfG interactions were abolished by alanine substitutions of the three residues of the conserved GYP motif in the HD-GYP domain. Changing the GYP motif or deletion of the two GGDEF-domain proteins reduced Xcc motility but not the synthesis of extracellular enzymes or biofilm formation. RpfG-GGDEF interactions are dynamic and depend on DSF signaling, being reduced in the rpfF mutant but restored by DSF addition. The results are consistent with a model in which DSF signal transduction controlling motility depends on a highly regulated, dynamic interaction of proteins that influence the localized expression of cyclic di-GMP.

Effect of solvent on the adsorption behavior and on the surface properties of Sterculia striata polysaccharide

Characterization of Sterculia striate polysaccharide (SSP) films adsorbed onto Si wafers from solutions prepared in ethyl methyl imidazolium acetate (EmimAc), water or NaOH 0.01 mol/L was systematically studied by means of ellipsometry, atomic force microscopy and contact angle measurements. SSP adsorbed from EmimAc onto Si wafer as homogeneous monolayers (similar to 0.5 nm thick), while from water or NaOH 0.01 mol/L SSP formed layers of similar to 4.0 nm and similar to 1.5 nm thick, respectively. Surface energy values found for SSP adsorbed from EmimAc or water were 68 +/- 2 mJ/m(2) and 65 +/- 2 mJ/m(2), respectively, whereas from NaOH it amounted to 57 +/- 3 mJ/m(2). The immobilization of lysozyme (LYS) onto SSP films was also investigated. The mean thickness of LYS (d(LYS)) immobilized onto SSP films adsorbed from each solvent tended to increase with the decrease of gamma(P)(S) and gamma(total)(S). However, the enzymatic activity of LYS molecules was higher when they were immobilized onto SSP films with higher gamma(P)(S) and gamma(total)(S) values. (C) 2010 Elsevier Ltd. All rights reserved.

Translation, Communication and 'Learning' : Experiences from teaching a master program in Viet Nam

In Vietnam, as in other Asian countries, co-operation with foreign universities plays an important role for the development of higher education. This paper is based on personal experiences from teaching a Swedish Master Programme in Education Science at Vietnam National University in Hanoi. Using theories developed by Lev Vygotsky and Donald Schon, the programme is explored as an inter-cultural learning process. Three aspects are focused upon. Firstly, the fact that communication between students and teachers is conducted with the help of translators who support both teachers and students in their attempt to understand and make themselves understood. Secondly, the expressed need to connect the ideas and techniques which are studied in the programme to the students´ professional worlds. Thirdly, the need to construct a framework wherein the students can inquire into their own situations and to encourage them to try new and more productive ways to deal with problems they are confronted with.

Att skola mångfalden – ett nationalistiskt försök : En analys av sverigedemokraternas diskurs om det goda samhället och den goda skolan kopplat till skolansvärdegrund

This essay attempts to examine the discourse of the Sweden democrats in relation to thevalue system of the Swedish national school.To analyse the political texts I use discourse analysis and especially the method and approachconducted by Judith Lee Bacchi. Bacchi focuses on the construction of a problem in variouspolitical discourses. When performing this kind of analysis the main question is (accordingto Bacchi): ”What is the problem represented to be?”I find that the Sweden democrats construct the ”migration politics” and the ”multiculturalpolitics” that is guiding the society as the cause of most problems in our society. To solvethe ”problems” they promote a nationalistic and a cultural racist discourse especiallypinpointing the ”Muslims” as being a problem.Since the Sweden democrats are striving to implement their discourse in the society andschool, and since their discourse already are reproduced by solar students in the classroom,I find it important to examine the essence of their particular discourse and contrast it withthe current value system of the Swedish schools.I don´t find the nationalistic and racist discourse of the Sweden democrats to correspond tothe value system of the Swedish school, mainly due to their strive to create alienation, andby labeling individuals in a reductive manner, instead of using apparent differences as asource for democratic discussions in the classroom

Materialising bodies : there is nothing more material than a socially constructed body.

Over the last one of two decades, researchers within the physical education (PE) and sport pedagogy research frequently use the concept ‘the material body’. An initial purpose of this article is to explore what a concept of a ‘material body’ might mean. What other bodies are there? Who would dispute the materiality of bodies? I suggest that the use of a concept as ‘the material body’ suggests a hesitation before the radicalism of the linguistic turn in the sense that the concept ‘discourse’ does not include a material dimension. In this way ‘the material body’ relates to an interpretation of ‘the socially (or discursively) constructed body’ as void of matter. A further purpose with the article is to re-inscribe matter in the concept of ‘discourse’. This is done by way of discussing what theorists like Michel Foucault and, in particular, Judith Butler, has to say about the materiality of the body. In their writings, discourse should not be limited to spoken and/or written language. Rather, discourse is understood in terms of actions and events that create meanings—that matters. One conclusion of the article is that it is important to problematise the mundane view of discourse as ‘verbal interchange’ because it reinforces the promise of an objective knowledge that will eventually shed light on the ‘real’ body and the mysteries of sexual difference, what its origins are, what causes it. Another conclusion is that the PE and sport pedagogy research should pay less attention to the body as an object (what it ‘is’), and pay more attention to how the body matters, and e.g. how movements make bodies matter.

Self-help and self-censorship: A self-help cultural perspective on organizational silence This paper seeks to explain silence in the workplace through an analytical perspective derived from Judith Butlers work on censorship, and in this way suggest an alternative to explanations in the existing literature on employee silence, which are often tied to the actions and motivations of the individual subject. It is thus argued that self-help books can be seen as indicative of a pervasive culture of self-improvement, which among other things promotes the absence of criticism in the workplace. The empirical point of departure for this argument is the two bestselling self-help books The secret by Rhonda Byrne and The 7 habits of highly effective people by Stephen Covey. Theoretically, the paper applies Butlers notion of ”implicit censorship” where censorship is understood as productive in the sense of being constitutive of language. Hence, in the analysis it is shown how discursive regimes in self-help literature tend to be constructed in such a way, that explicit criticism cannot emerge as a meaningful activity, and is thus implicitly censored.

Scriptural Archeology: Excavating the Presence of Women in the Torah

Women's roles in religious history have been traditionally described in terms of their relation and value to men. The normative religious texts provide an androcentric perspective on the gender relationships within the early community, the growth of Judaism in "Jacob's House" and the monotheistic worship of God. Yet these literary representations omit an entire half of the experience of the Jewish community: the perspective and participation of women. As Judith Plaskow argues extensively in Standing Again at Sinai, women are defined not in her own terms or in her own voice, but by her relationship and value to men through the androcentric vocabulary of the Torah. This statement is textually illustrated by the authorial and editorial presentation of women and their place in ancient Israelite society in the Torah. As Judaism grew increasingly androcentric in its leadership, women were increasingly reduced to marginal figures in the community by authorial and editorial revisions. Yet the participation of women of ancient Israel is not lost. Instead, the presence of women is buried beneath the androcentric presentation of the early Judaic community, waiting to be excavated by historical and scriptural examination. The retelling of the past is influenced by the present; memory is not static but takes on different shapes depending on the focus of concentration. However, tradition greatly influences the interpretation of religious history as well. In the book of Genesis, the literature emphasizes the divine appointment of male figures such as Abraham the father of the covenant and Jacob who is renamed and claimed by God as "Israel," placing them at the center of Jewish history. As a result, the other figures in these biblical narratives are described in relation to the patriarchs, those male bearers of the covenant, by their service or their value to him. Women are at the bottom of this hierarchy. Although female figures of exceptional quality are noted in later chronicles, such as Ruth, Deborah and Miriam, it is the very nature of their exception that highlights the androcentric editorial focus of the Torah. I agree with Peggy Day, whose own scriptural examination in Gender and Difference in Ancient Israel, makes the important distinction between the literary representation and the reality of ancient Israelite culture: they are not coextensive nor equivalent. Although the text represents the culture of ancient Israel as male dominated from the time of Abraham, this presentation omits the perspective of half of the population-the women. By beginning at the point of realization that women did exist and were active in their culture, and placing aside the androcentric perspective of the text and its editors, the reality of women's place in ancient Israel may be determined. Through this new perspective, the women of the Torah will emerge as the archetypes of strength, leadership and spiritual insight to provide Jewish women of the present with female, ancestral role models and a foundation for their gender's heritage, a more complete understanding of the partial record of Jewish history recorded in the Torah. Those stories that appear as the exception of women's presence will unveil an exceptional presence. As Tamar Frankiel eloquently states in The Voice of Sarah, "the women we call our 'Mothers'-Sarah, Rivkah (Rebekah), Rachel, and Leah-are not merely mothers, any more than the 'Fathers'-Abraham, Isaac and Jacob-are merely fathers "(Frankiel 5).
