Review Essay: How Critical Discourse Analysis Faces the Challenge of Interpretive Explanations from a Micro- and Macro-theoretical Perspective

Zu Beginn wird ein knapper Uberblick zu aktuellen Veroffentlichungen und den historischen Wurzeln der Kritischen Diskursanalyse (KDA) gegeben. Die anschliesende Rezension des Sammelbandes orientiert sich an den von den HerausgeberInnen, Ruth WODAK and Gilbert WEISS, beschriebenen KDA-Merkmalen: 1) Klarung der zentralen KDA-Begriffe, 2) die Erzeugung sowohl verstehend-erklarender als auch kritischer Erkenntnisse aufgrund der relationierenden Verknupfung von institutionellen, strukturellen mit text-/diskursspezifischen, pragmatischen Dimensionen und 3) die methodisch kontrollierte Genese von Konstruktionen zweiter Ordnung. Mithilfe dieser Aspekte verdeutlicht der Rezensionsaufsatz, inwiefern die einzelnen Artikel beachtenswerte Thesen, Suchstrategien und Forschungsergebnisse beinhalten, v.a. im Hinblick auf die selbst-reflexive Kritik des "Kritischen" oder die Situation benachteiligter und diskriminierter Gruppenmitglieder in unterschiedlichen Handlungsfeldern. Dabei prasentiert sich die KDA als ein interdisziplinares, unabgeschlossenes Projekt, das sich um die Erfullung hoher empirischer Standards sowohl der Linguistik als auch der Sozialwissenschaften bemuht. Diesem Anliegen sind denn auch die Hinweise der Rezensentin u.a. auf die systematischen Unterschiede zwischen Grundlagen- und Verwendungsforschung sowie auf die umfassende Operationalisierung einer Handlungstheorie verpflichtet.

Do new democracies deliver social welfare? Political regimes and health policy in Ghana and Cameroon

Democratic reform processes often go hand in hand with expectations of social welfare improvements. While the connection between the emergence of democracy and the development of welfare states in the West has been the object of several studies, however, there is a scant empirical literature on the effects of recent democratization processes on welfare policies in developing countries. This is particularly true for Africa. In a dramatically poor environment, Africans often anticipated that the democratic reforms many sub-Saharan states undertook during the early 1990s would deliver welfare dividends. This article investigates whether and how the advent of democracy affected social policies – focusing, in particular, on health policy – by examining one of the continent's most successful cases of recent democratization (Ghana) and comparing it with developments in a country of enduring authoritarian rule (Cameroon). Evidence shows that democracy can indeed be instrumental to the expansion and strengthening of social policies. In Ghana, new participatory and competitive pressures pushed the government towards devising and adopting an ambitious health reform. Despite façade elections, no similar pressures could be detected in undemocratic Cameroon and health policy remained almost entirely dictated by foreign donors.
Analyzing the Correlation of Serum Iron Parameters with Paraoxanase, Arylesterase and Oxidative Stress Markers in Stem Cell Transplantation Patients

Background: Hematopoietic Stem Cell Transplantation (HSCT) itself is associated with morbidity and mortality, and impaired iron metabolism might have an impact on these complications. Iron, ferritin overload in tissues and systemic circulation, is importantly thought that (to) increase the oxidative stress. Methods: In patients and controls serum iron, iron binding capacity and ferritin levels were measured. Antioxidant enzymes, Catalase (CAT), Glutathione peroxidase (GPx), Paraoxonase (PON), Arylesterase (ARE), and Glutathione-s Transferase (GST) activities were measured in the serum. These parameters and enzymes in relevance to malondialdehyde (MDA) were evaluated. Results: Serum MDA levels were significantly increased in the autologous group compared with the control group (p 0.05). Serum PON activity levels in autologous were found to be low when compared with the control group (p < 0.05). In terms of serum iron levels, statistically significant difference were found between allogeneic, autologous and the control group (p < 0.05). Serum ferritin levels were found high in allogeneic and autologous groups than the control group (p < 0.05). According to Spearman’s correlation analysis, between serum MDA level and GPx activity in serum, a negative correlation was found. Between serum MDA and serum GST, and between serum PON activity and serum ARE activity were found a positive correlation. Conlusions: Serum and tissues ferritin overload and the decrease in antioxidative enzymes activity levels may be harmful to body, causing some types of blood cancer diseases.
Cobalt ( III ) , nickel ( II ) and ruthenium ( II ) complexes of 1 , 10-phenanthroline family of ligands : DNA binding and photocleavage studies

DNA binding and photocleavage characteristics of a series of mixedligand complexes of the type [M(phen)2LL] n+ (where M = Co(III), Ni(II) or Ru(II), LL = 1,10-phenanthroline (phen), phenanthroline-dione (phen-dione) or dipyridophenazine (dppz) and n = 3 or 2) have been investigated in detail. Various physico-chemical and biochemical techniques including UV/Visible, fluorescence and viscometric titration, thermal denaturation, and differential pulse voltammetry have been employed to probe the details of DNA binding by these complexes; intrinsic binding constants (Kb) have been estimated under a similar set of experimental conditions. Analysis of the results suggests that intercalative ability of the coordinated ligands varies as dppz > phen > phen-dione in this series of complexes. While the Co(II) and Ru(II) complexes investigated in this study effect photocleavage of the supercoiled pBR 322 DNA, the corresponding Ni(II) complexes are found to be inactive under similar experimental conditions. Results of detailed investigations carried out inquiring into the mechanistic aspects of DNA photocleavage by [Co(phen)2(dppz)] 3+ have also been reported.
Ligninolytic enzymes production by Dichostereum sordulentum cultures in the presence of Eucalyptus bark as a natural laccase stimulator

A strain of a fungal species, i.e., Dichostereum sordulentum , not yet isolated from either Uruguay or decayed Eucalyptus spp. wood, was investigated for its ability of producing extracellular ligninolytic enzymes. To this aim, the strain was grown on a N-rich liquid medium added with either bark or wood Eucalyptus dunnii sawdust. The former additive was more effective than the latter instimulating laccase leading to a production of 4.78 IU mL -1 which was further enhanced by the concomitant presence of 80 ppm CuSO 4 (6.56 IU mL -1 ). The two order of magnitude higher proanthocyanidin content in bark than in wood suggests that this fraction might be responsible for the higher stimulatory effect of the former on laccase production.
Reactive Red (RR141) Solution Adsorption by Nanochitin Particle via XAS and ATR-FTIR Techniques

Adsorption of reactive dye solution on nanochitin and chitin particle under acidic, neutral and basic condition was studied. The percentage adsorption of reactive dye solution on nanochitin and chitin under basic condition was 98% and 59%, respectively. In this study, we used ATR-FTIR spectroscopy to study the adsorption mechanism between nanochitin and reactive dye. The results indicated that the amine group of nanochitin was a functional group for the adsorption of Reactive Red (RR141) under acidic condition while the hydroxyl group of nanochitin was the main site for adsorption of Reactive Red (RR141) under basic condition. Azo group (N=N) of reactive dye might be electron donor, while amide group (-CONH2) of nanochitin was electron acceptor under neutral condition. XAS spectra obtained the changes of S atom in RR141 adsorbed onto nanochitin under acidic, whereas adsorption under neutral and basic condition caused no change in the form of S- atom in the dye.
Effective Detection, Isolation and Characterization of Dakaramine from Ghanaian Axinella sp and Bioactivity Keywords: Iodotyramine; Acetamide; Bioaccumulation; Jurkat

The Ghanaian sponge Axinella sp collected for the first time from the Gulf of Guinea yielded similar amounts of dakaramine (1), acetamide and a new hydroxylated acetate metabolite (2). The structures of these metabolites were elucidated by 1D and 2D NMR data interpretation. The halogens in dakaramine were detected by high performance liquid chromatography coupled with inductively coupled plasma and electrospray ionization mass spectrometry (HPLC-ICPMS/ESMS), a technique that allows for heteroatoms and metals in organic compounds to be detected specifically and with very high sensitivity. Cytotoxicity of dakaramine was assessed in vitro using two human cancer cell lines, human lymphocytic cell (Jurkat) and acute promyelocytic leukemia (HL60). This compound was found to be acutely toxic to these cell lines with IC50 values of 35.0 and 26.5 µg/ml respectively.
Intertree competition in uneven-aged ponderosa pine stands

Intertree competition indices and effects were examined in 14 uneven-aged ponderosa pine (Pinus ponderosa var. scopulorum Engelm.) stands in eastern Montana. Location, height, diameter at breast height (DBH), basal area in- crement, crown ratio, and sapwood area were determined for each tree (DBH >3.8 cm) on one stem-mapped plot (0.2- 0.4 ha) in each sample stand. Based on tree locations, various competition indices were derived for each sample tree and correlated with its growth efficiency by diameter class. In addition, trends in individual tree attributes by diameter class and level of surrounding competition were determined. For trees with a DBH 3,8 cm) dans une placette (0,2-0,4 ha) dont les tiges ont ete cartographiees. Sur la base de la localisation des arbres, differents indices de competition ont ete deri- ves pour chaque arbre et correles avec leur efficacite de croissance par classe de diametre. De plus, les tendances dans les attributs des arbres ont ete determinees par classe de diametre et par niveau de competition avoisinante. Pour les ar- bres avec un DHP <10 cm, l'efficacite de croissance est plus fortement correlee avec la somme de la hauteur des ar- bres avoisinants situes a moins de 10,6 m. Pour les arbres plus gros, l'indice le plus fortement correle correspond a la somme de la surface terriere des arbres voisins situes a moins de 6,1 m. Independamment de la taille des arbres, l'effi- cacite de croissance des arbres, l'accroissement en surface terriere et la proportion de houppier diminuaient avec l'aug- mentation des niveaux de competition, avec un effet plus prononce pour les petits arbres. Ces resultats montrent que les arbres des peuplements inequiennes subissent une competition provenant de sources differentes a des echelles varia - bles, en fonction de leur taille et avec une reponse a la competition qui diminue a mesure que la taille de l'arbre aug - mente.
On the long run relationship between industrial construction and housing

Most empirical analysis of property development treats the subcomponents of the construction industry as independent. For example, models of housing construction typically do not consider any relationship with industrial or commercial construction. In fact, there are a number of ways in which changes over time may be interdependent. For example, economic theory suggests that, under some conditions, housing investment crowds out industrial and commercial investment. In general, therefore, if there are interdependencies, the presumption is that the relationship is negative. Here the relationship between new housing and industrial construction is concentrated on. It is found that, in the long run, based on Johansen tests for Britain since the sixties, the relationship is positive - movements are complementary. At first sight, this result is counter-intuitive, at least in an aspatial setting. But, in a spatial setting, the results are consistent with the view that (i) 'jobs move to workers' as relocating firms seek out highly skilled workers who, in turn, search for high quality housing locations; (ii) particularly in SE England, which has a high rate of new firm formation, fast growing new firms are started by high potential entrepreneurs close to where they live. Therefore, new housing and industrial development are self-reinforcing.
Novel Broadband Equalizer Optimization Technique for High-Speed Digital System Designs

In this paper, a novel broadband equalizer optimization technique is introduced for highspeed digital system designs. Through effectively compensating both conductor loss and dielectric loss, this technique provides a new solution to find optimal equalizer for high-speed signaling over printed circuit board (PCB) with continuous time linear equalizer (CTLE) as an application. The coefficients of CTLE are quickly identified through searching the minimum of the variation of total transfer functions over the low-mid frequency range. Channel simulations with different server interfaces of 12 Gbps and 25 Gbps are performed, respectively. Simulation results are presented to validate the technique.
Comparative analysis of halophilic microbial populations at Lake Tyrrell, Australia

The study of life at extreme environments helps us better understand the limits of where organisms can exist and how life adapts to survive. We are studying Lake Tyrell, south-eastern Australia, to gain information on life that survives in a specific extreme environment: evaporitic environments. Possible applications of studying the lake are evolution, biotechnology, and an analog for possible conditions on Mars and primitive Earth. A comparative analysis was conducted on halophilic microorganisms found in planktonic samples and microorganisms found in salt at Lake Tyrrell. As water evaporates from the lake, salinity increases and salt crystals form. When the crystals form, water is trapped within the matrix, and microbes can be found in these fluid inclusions. This study compares microbial populations trapped within salt crystals with previously studied halophilic microbial populations present free-floating in the lake. The DNA from two microbial populations were sequenced: planktonic populations and salt populations. From this, 16S clone libraries and an Archaea and a Bacteria phylogenetic tree with both populations was created. By attempting to study what halophiles are present in the salts through the sequencing of DNA, we have taken another step towards discovering what is viable in these salt crystals and thus what life can possibly survive in different and possibly new environments.
An Isometric Imbedding Theorem for Holomorphic Bundles

The main result in this paper concerns special Hermitian metrics on vector bundles over certain compact complex manifolds. These metrics are not necessarily isometric pullbacks of the Euclidean metric on the universal bundle over a Grassman manifold, but become so after tensoring sufficiently often with a line bundle. The result generalizes to this context a concrete theorem the authors proved in [CD1] about bihomogeneous polynomials on complex Euclidean space
Exchange Rate Pass-Through to Manufactured Import Prices: The Case of Japan

This paper examines the exchange rate pass-through to yen based manufactured import prices of Japan using asymmetric unit root and cointegration tests and asymmetric models. Due to sticky prices, for example, there are reasons to believe that the degree of pass-through depends on whether the exchange rate appreciates or depreciates. The sample used in this study covers the period January 1975 to June 1997. Using two state regime switching models, the estimated pass-through coefficients corresponding to appreciation and depreciation of the currency are found to be 98 percent and 83 percent respectively; these coefficients are shown to be significantly different, particularly in the post recession period. Moreover, we have shown that the recession in Japan in the 1990s has significantly affected the exchange rate passthrough relationship particularly when the yen depreciates and that the proposition that exchange rate depreciation and appreciation have systematic asymmetric effects on exchange rate pass-through coefficient. Forcing appreciations and depreciations to have the same effects on the import prices does not appear to uncover the true underlying exchange rate pass through relationship.
Utilizing Universal Probability of Expression Code (UPC) to Identify Disrupted Pathways in Cancer Samples

Utilizing Universal Probability of Expression Code (UPC) to Identify Deregulated Pathways in Cancer Samples Michelle R. Withers Department of Statistics, BYU Master of Science Understanding the role of deregulated biological pathways in cancer samples has the potential to improve cancer treatment, making it more effective by selecting treatments that reverse the biological cause of the cancer. One of the challenges with pathway analysis is identifying a deregulated pathway in a given sample. This project develops the Universal Probability of Expression Code (UPC), a profile of a single deregulated biological pathway, and projects it into a cancer cell to determine if it is present. One of the benefits of this method is that rather than use information from a single over-expressed gene, it provides a profile of multiple genes, which has been shown by Sjoblom et al. (2006) and Wood et al. (2007) to be more effective. The UPC uses a novel normalization and summarization approach to characterize a deregulated pathway using only data from the array (Mixture model-based analysis of expression arrays, MMAX), making it applicable to all microarray platforms, unlike other methods. When compared to both Affymetrix’s PMA calls (Hubbell, Liu, and Mei 2002) and Barcoding (Zilliox and Irizarry 2007), it performs comparably.
Automatic Exchange of Scheduling Methods for Clusters

Due to still increasing demand for computing power, the efficient utilization of computational clusters is becoming more and more important. During the process of utilizing such clusters, different sometimes conflicting objectives like the maximization of the overall system utilization or the minimization of the energy consumption have to be incorporated into the scheduling decision process. Therefore, the ability to dynamically adapt to changing demands becomes a highly desirable feature of cluster schedulers and job management systems. In this paper, we describe a cluster scheduling system that can automatically adapt itself to the changing system states within the cluster. Based on the different resource measurements, it can update different parameters of the scheduling policy that is currently in place or dynamically exchange the whole scheduling policy. Note that the new scheduling policy does not need to be defined at the system start. That is, the administrator can define new strategies during the runtime that are dynamically integrated. To this end, we present the main components which form our scheduling system: the Pluggable Probes and Scheduling Policies Framework and the Scheduling Configuration Changer. Furthermore, we discuss different advantages and disadvantages of our approach.
Potential for Solar System Science with the ngVLA.

Radio wavelength observations of solar system bodies are a powerful method of probing many characteristics of those bodies. From surface and subsurface, to atmospheres (including deep atmospheres of the giant planets), to rings, to the magnetosphere of Jupiter, these observations provide unique information on current state, and sometimes history, of the bodies. The ngVLA will enable the highest sensitivity and resolution observations of this kind, with the potential to revolutionize our understanding of some of these bodies. In this article, we present a review of state-of-the-art radio wavelength observations of a variety of bodies in our solar system, varying in size from ring particles and small near-Earth asteroids to the giant planets. Throughout the review we mention improvements for each body (or class of bodies) to be expected with the ngVLA. A simulation of a Neptune-sized object is presented in Section 6. Section 7 provides a brief summary for each type of object, together with the type of measurements needed for all objects throughout the Solar System.

Measuring and modeling the spectrum of fine‐root turnover times in three forests using isotopes, minirhizotrons, and the Radix model

Fine root (<2 mm) cycling rates are important for understanding plant ecology and carbon fluxes in forests, but they are difficult to determine and remain uncertain. This paper synthesizes minirhizotron and isotopic data and a root model and concludes that (1) fine roots have a spectrum of turnover times ranging from months to many years and (2) the mean age of live root biomass (A) and the mean age of roots when they die (i.e., their turnover time (τ)) are not equal. We estimated A and τ of fine roots in three forests using the root model Radix. For short‐lived roots, we constrained τ with existing minirhizotron data; for long‐lived roots, we used new radiocarbon measurements of roots sampled by diameter size class and root branch order. Long‐lived root pools had site mean τ of 8–13 y and 5–9 y when sampled by diameter and branch order, respectively. Mean turnover times across sites were in general not significantly different as a function of branch‐order, size class, or depth. Our modeling results indicate that ∼20% of fine root biomass has turnover times of about a year, and ∼80% has decadal turnover times. This partitioning is reflected in our predicted mean ages of ∼9 y and turnover times of ∼3 y. We estimate that fine root mortality contributes between 38 and 104 g C m−2 y−1 to soil in these forests. These estimates are 20 to 80% of previous estimates in these and similar forests, in part because we explicitly account for the large portion of fine‐root biomass with decadal cycling rates. Our work shows that both fast and slow cycling roots must be modeled jointly to account for the heterogeneous nature of fine‐root dynamics.
