Be(coming) the Change You Want to See in the World: Social Justice Teacher Education as Affective Craft

This dissertation begins from the difficulty faced by the field of social justice teacher education (SJTE) in setting itself apart from other aspects of teacher education. SJTE’s history of internal and external evidence pressures has distracted the field from reckoning with ‘social justice’ as a moving horizon and not a static outcome against which it can be found effective. If ‘social justice’ cannot be the outcome holding SJTE together and apart from other kinds of teacher education, how does SJTE work? To answer this question, I use Deleuzo-Guattarian and affect theories to position SJTE as an assemblage: an ever-becoming whole composed of the relations among its non-sovereign yet affecting/affected components. In the first analytical chapter, I assemble what SJTE is, does and wants by analyzing 58 field-defining texts. Regardless of what SJTE may say about itself, the field is characterized by an affective capacity to inhabit irresolvable tensions; this capacity expresses assemblage becoming and, therefore, an incremental conception of social change. The second and third analytical chapters analyze the SJTE-assemblage at the level of everyday life. Through multi-sensory fieldwork at education conferences and experimental conversations with practitioners, I tracked moments of intensity bordering on rupture. These were frequently events unthinkable among ‘equity experts’ yet recalling familiar forms of student resistance. In the second chapter, I investigate what happens at these thresholds where SJTE threatens to come apart. In the third chapter, I assemble an emergent theory of resistance that challenges prevailing conceptions of SJTE practice ‘gone wrong.’ My findings reveal the implicit ways in which SJTE reckons with ‘social justice’ as a moving horizon. Although SJTE tends toward political and conceptual rigidity, I identified its enacted and unspoken flexibility in how e.g., race or sexuality can emerge otherwise in everyday life. This capacity of openness to the surprises of social difference or difference-to-come is a pivotal yet unnamed contribution of the field that is expressed in its craft. I conclude by envisioning how SJTE might explicitly attend to depth – the sovereign political will of teachers as agents of social change – and surface: what is affective, implicit and pre-personal.

Root systems and diagram calculus. III. Semi-Coxeter orbits of linkage diagrams and the Carter theorem

A diagram obtained from the Carter diagram $Γ$ by adding one root together with its bonds such that the resulting subset of roots is linearly independent is said to be the {\it linkage diagram}. Given a linkage diagram, we associate the linkage labels vector, which is introduced like the vector of Dynkin labels. Similarly to the dual Weyl group, we introduce the group $W^{\vee}_L$ associated with $Γ$, and we call it the dual partial Weyl group. The linkage labels vectors connected under the action of $W^{\vee}_L$ constitute the linkage system $\mathscr{L}(Γ)$, which is similar to the weight system arising in the representation theory of the semisimple Lie algebras. The Carter theorem states that every element of a Weyl group $W$ is expressible as the product of two involutions. We give the proof of this theorem based on the description of the linkage system $\mathscr{L}(Γ)$ and semi-Coxeter orbits of linkage labels vectors for any Carter diagram $Γ$. The main idea of the proof is based on the fact that, with a few exceptions, in each semi-Coxeter orbit there is a special linkage diagram -- called {\it unicolored}, for which the decomposition into the product of two involutions is trivial.

GLUT4 protein expression in obese and lean 12-month-old rats: insights from different types of data analysis

GLUT4 protein expression in white adipose tissue (WAT) and skeletal muscle (SM) was investigated in 2-month-old, 12-month-old spontaneously obese or 12-month-old calorie-restricted lean Wistar rats, by considering different parameters of analysis, such as tissue and body weight, and total protein yield of the tissue. In WAT, an approximately 70% decrease was observed in plasma membrane and microsomal GLUT4 protein, expressed as microg protein or g tissue, in both 12-month-old obese and 12-month-old lean rats compared to 2-month-old rats. However, when plasma membrane and microsomal GLUT4 tissue contents were expressed as g body weight, they were the same. In SM, GLUT4 protein content, expressed as microg protein, was similar in 2-month-old and 12-month-old obese rats, whereas it was reduced in 12-month-old obese rats, when expressed as g tissue or g body weight, which may play an important role in insulin resistance. Weight loss did not change the SM GLUT4 content. These results show that altered insulin sensitivity is accompanied by modulation of GLUT4 protein expression. However, the true role of WAT and SM GLUT4 contents in whole-body or tissue insulin sensitivity should be determined considering not only GLUT4 protein expression, but also the strong morphostructural changes in these tissues, which require different types of data analysis.

CONSTITUTIONAL DOCUMENTS OF THE KEHILA ASHKENAZI IN MEXICO

The Ashkenazijews arrived in Mexico at the beginning of the twentieth century. Being few in number, they prayed in the same small place as Jews ofSephardi descent. Yet differences between both groups appeared almost immediately because of the different styles of prayer service. These differ ences forced the Ashkenazi Jews to leave and search for a place of their own. This event can be considered as the initiation of the Kehild Ashkenazi in Mexico, which occurred in 1922. This study presents five early documents in Spanish related to this founding and its development through the following seventy years.

Advanced Technology and Analytical Methods for Assessing the Impact of Anticancer Drug Metabolites on Drug Efficacy and Toxicity

This study focuses on advancing the analysis of anticancer drug metabolites by integrating cutting-edge analytical and computational techniques. To improve the separation and identification of metabolites, we employ advanced chromatographic methods, including Ultra-Performance Liquid Chromatography (UPLC) coupled with high-resolution mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectroscopy. These techniques provide enhanced resolution and accuracy in metabolite profiling. Computational approaches, such as molecular dynamics (MD) simulations and quantum mechanical (QM) calculations, are utilized to predict metabolic pathways and identify novel metabolites, while quantitative structure-activity relationship (QSAR) models assess biological activity and potential toxicity. The study reveals that Metabolite A exhibits high binding affinity and favorable reaction energy, suggesting its significant role in drug efficacy, whereas Metabolite B, despite lower binding affinity, shows higher potency and may contribute substantially to therapeutic effects. In contrast, Metabolite C, with the lowest binding affinity and less favorable reaction energy, presents potential safety concerns. This integrated methodology highlights the importance of combining advanced analytical techniques with computational models to optimize drug development and personalized medicine. The findings underscore the potential for improved therapeutic efficacy and safety in oncology through detailed metabolite analysis.

Abnormal blood chemistry data in Cushing's syndrome: Comparison with those for fatty liver.

It has been reported that fatty liver is not uncommon in Cushing's syndrome. Biochemical data obtained from routine blood chemistry in 10 patients with Cushing's syndrome were compared with those for 15 patients with histologically verified fatty liver. We found an absence of a decreased GOT/GPT ratio, low normal choline esterase and increased lactic dehydrogenase activities together with lowered serum protein and albumin, and increased blood sugar and total cholesterol in Cushing's syndrome when compared with those of fatty liver cases. These data and additional findings in liver histology obtained from one patient with Cushing's syndrome due to adrenocortical carcinoma indicated that fatty changes in the liver were not frequently encountered in Cushing's syndrome. These abnormal biochemical data might be a way of distinguishing Cushing's syndrome from fatty liver.

Pulsars and Compact Extragalactic Objects Epstein, Richard I. ; Petrosian, Vahe Abstract We discuss some limitation on synchrotron models for optical pulsars and compact extragalactic objects. Using the results of the previous paper, we show that several existing models for the pulsar NP 0532 are inconsistent with the measured time variations and polarization of the optical emission. We also consider whether the low-frequency falloffs in some extragalactic objects (PKS 2134+004, OQ 408, and NGC 1068) could be due to emission from particles with small pitch angles, absorption by a thermal plasma, or synchrotron self-absorption. We find that radiation by particles with small pitch angles could explain the radio emission from PKS 2134+004 and OQ 208, but this process is inconsistent with the observations of NGC 1068. The absorption interpretations cannot account for the turnover in the spectrum of PKS 2134+004. Measurements of polarization, angular structure, and X-ray flux would be helpful in evaluating these models.

Simultaneous removal of NO<sub><i>x</i></sub>and SO<sub>2</sub>from NO-SO<sub>2</sub>-CO<sub>2</sub>-N<sub>2</sub>-O<sub>2</sub>gas mixtures by corona radical shower systems

In this study, an experimental investigation has been conducted to remove NOx and SO2 simultaneously from NO-SO2-CO2-N2-O2 gas mixtures using a d.c. corona discharge activated radical shower system. The gas mixtures consisted of NO-SO2-CO2-N2-O2([NO]o:200 ppm and [SO2]o:800 ppm) and the injection gas used as the radical source gas was NH3-Ar-air. The effect of NH3 radical injection rate on the NOx and SO2 removal efficiency and other by-product gases was measured by Fourier transform infrared (FTIR), as well as SO2, NOx and NO2 gas detectors. By-product aerosol particles were also observed using a condensation nucleation particle counter (CNPC) and SEM imaging after sampling. The results showed that significant aerosol particle formation was observed during simultaneous NOx and SO2 removal by corona radical shower systems. Electrode surface conditions had a significant influence on the NOx and SO2 removal characteristics. The NOx removal efficiency significantly increased with increasing applied voltage and NH3 injection rate. The SO2 removal efficiency was not significantly affected by applied voltage and slightly increased with increasing acid gas to NH3 molecular ratio.

Synthesis and Properties of Alphatic Polyurethanes and Model Compounds Containing Alpha, Alpha, Alpha Prime, Alpha Prime - Tetramethyl-p-Xylylene-Diisocyanate.

New materials are needed to replace the rubber compounds which are in current use in certain high stress environments. The rubber materials usually fail due to the high internal temperature which results from compressive cycling under heavy loads. Rubber formulations, such as styrene-butadiene, also fail due to severe mechanical stresses, such as tearing forces. Polyurethanes are being examined as possible replacements due to indications of better mechanical strength. However, hysteric heat buildup in polyurethanes is a major problem. Investigation of the molecular arrangement of the polyurethane samples was made using infrared and X-ray scattering techniques. Low molecular weight model compounds, simulating the polar regions of the polyurethanes, were prepared and characterized by single crystal X-ray diffraction by Dr. Jerry P. Jasinski. Compressive fatigue tests were conducted on some samples which showed good thermal resistance by other tests. The model compounds of p-TMXSI provided information on the possible conformation of this unique structure in the polyurethane chains. Until recently, polyurethanes made from diphenylmethane-4,4'-diisocyanate were the only polyurethane class which had been characterized by X-ray scattering and X-ray crystallographic techniques.

“Wading Through Sludge”: An Interpretative Phenomenological Analysis of Parental Experiences of Child Feeding in the Context of Avoidant Eating

Responsive feeding is an approach to feeding children that prioritises child autonomy and supports children’s ability to regulate their energy intake. Alongside innate and developmental factors, nonresponsive feeding practices - specifically pressure to eat - are associated with increased avoidant (‘picky’) eating, a common parenting challenge. Although much is known about associations between feeding practices and child eating behaviours, an in depth understanding of the parental perspective is lacking. This programme of research comprises a systematic review of the conceptualisation of pressure to eat and a qualitative study: an interpretative phenomenological analysis of maternal meaning making in relation to their feeding practices and their child’s eating behaviours. The study is unique in its methodology and its sample (UK mothers of nonclinical avoidant eaters seeking support from their health visitor). Ten participants were recruited and data were gathered using semi-structured interviews. It was found that current or past use of pressure to eat was ubiquitous in this sample. This was captured by the superordinate theme ‘Getting the food down the child’. Three further superordinate themes were identified. These concerned maternal agency, identity, and attempts to understand. It is argued that participants experienced child feeding as an unwinnable battle, their only options being to fight on in vain or submit completely. There may be several factors contributing to this. First, a lack of knowledge, both of responsive feeding and common causes of avoidant eating. Secondly, a misinterpretation of aspects of the feeding literature, embedded in the contemporary parenting canon. Finally, a sense of hopelessness - participants felt they had tried everything, nothing worked, and no one had any answers. These findings comprise an original, fine-grained insight into maternal meaning making in the context of avoidant eating. They have implications for research and practice, especially regarding screening and support provided in primary care.

The acetylation of insulin

The acetylation of the free amino groups of insulin was studied by reaction of the hormone with N-hydroxysuccinimide acetate at pH6.9 and 8.5. The products formed were separated by chromatography on DEAE-Sephadex and were characterized by isoelectric focusing, by end-group analysis, by the incorporation of [3H]acetyl groups in the molecule, and by treatment with trypsin that had been treated with 1-chloro-4-phenyl-3-toluene-p-sulphonamidobutan-2-one (‘tosylphenylalanyl chloromethyl ketone’). Three monosubstituted products, two disubstituted products and one trisubstituted derivative were prepared. The α-amino groups of the terminal residues and the ∈-amino group of the lysine-B29 were the sites of reaction. Acetylation of any of the free amino groups did not affect the biological activity of insulin. It was demonstrated, however, that substitution at the glycine-A1 amino group by the larger residues, acetoacetyl or thiazolidinecarbonyl, produced a decrease in biological activity. Modification of the lysine-B29 or phenylalanine-B1 amino groups with these larger reagents did not affect the biological activity. Modification of the phenylalanine-B1 amino group by any of the three substituents resulted in a large decrease in the affinity of insulin for anti-insulin antibodies raised in the guinea pig. Modification of the other two amino groups did not affect the reaction with antibody. These observations are correlated with the tertiary structure of insulin.

3D-SCENE MODELING FROM IMAGE SEQUENCES

This contribution gives an overview of automatic 3D scene reconstruction and visualisation from uncalibrated and handheld camera image sequences. We address specifically the problems that are associated with calibration and visual-geometric reconstruction of complex scenes with occlusions and view-dependent surfaces. The scene is then represented by large sets of calibrated real viewpoints with image texture and depth maps. Novel views are synthesized from this representation with view-dependent image-based rendering techniques at interactive rates. 1

Effect of Particles on the Recovery of <i>Cryptosporidium</i> Oocysts from Source Water Samples of Various Turbidities

ABSTRACT Cryptosporidium parvum can be found in both source and drinking water and has been reported to cause serious waterborne outbreaks which threaten public health safety. The U.S. Environmental Protection Agency has developed method 1622 for detection of Cryptosporidium oocysts present in water. Method 1622 involves four key processing steps: filtration, immunomagnetic separation (IMS), fluorescent-antibody (FA) staining, and microscopic evaluation. The individual performance of each of these four steps was evaluated in this study. We found that the levels of recovery of C. parvum oocysts at the IMS-FA and FA staining stages were high, averaging more than 95%. In contrast, the level of recovery declined significantly, to 14.4%, when the filtration step was incorporated with tap water as a spiking medium. This observation suggested that a significant fraction of C. parvum oocysts was lost during the filtration step. When C. parvum oocysts were spiked into reclaimed water, tap water, microfiltration filtrate, and reservoir water, the highest mean level of recovery of (85.0% ± 5.2% [mean ± standard deviation]) was obtained for the relatively turbid reservoir water. Further studies indicated that it was the suspended particles present in the reservoir water that contributed to the enhanced C. parvum oocyst recovery. The levels of C. parvum oocyst recovery from spiked reservoir water with different turbidities indicated that particle size and concentration could affect oocyst recovery. Similar observations were also made when silica particles of different sizes and masses were added to seeded tap water. The optimal particle size was determined to be in the range from 5 to 40 μm, and the corresponding optimal concentration of suspended particles was 1.42 g for 10 liters of tap water.
