Gender, race, militarism and remembrance: the everyday geopolitics of the poppy

This article offers a feminist analysis of how British military violence and war are, in part, made possible through everyday embodied and emotional practices of remembrance and forgetting. Focusing on recent iterations of the Royal British Legion’s Annual Poppy Appeal, I explore how the emotionality, and gendered and racial politics of collective mourning provide opportunities for the emergence of ‘communities of feeling’, through which differently gendered and racialised individuals can find their ‘place’ in the national story. I aim to show that in relying on such gendered and racial logics of emotion, the Poppy Appeal invites communities of feeling to remember military sacrifice, whilst forgetting the violence and bloodiness of actual warfare. In so doing, the poppy serves to reinstitute war as an activity in which masculinised, muscular ‘protectors’ necessarily make sacrifices for the feminised ‘protected’. The poppy is thus not only a site for examining the everyday politics of contemporary collective mourning, but its emotional, gendered and racialised foundations and how these work together to animate the geopolitics of war.
Gluten-free bread with an addition of freeze-dried red and purple potatoes as a source of phenolic compounds in gluten-free diet

Abstract The basis for gluten-free diet is often gluten-free bread, which is usually characterized by a low-nutritional value, and lacks any pro-health properties. Only after an introduction of gluten-free raw materials, containing high level of bioactive compounds it would be possible to obtain the product with a pro-health potential. The aim of the study was to analyze the content of bioactive compounds (total phenolic content, phenolic acids, flavonoids, flavonols, anthocyanins and carotenoids) in gluten-free bread prepared with 5% addition of freeze-dried red and purple potatoes as well as to assess their antioxidant potential. Summarizing, among the analyzed gluten-free breads with an addition of freeze-dried red and purple potatoes, the best results could be obtained by using variety Magenta Love (red potato), which provided the highest levels of phenolic compounds and carotenoids and also antioxidant and antiradical activity.
Conditioned Reinforcement can be Mediated by Either Outcome-Specific or General Affective Representations

Conditioned reinforcers are Pavlovian cues that support the acquisition and maintenance of new instrumental responses. Responding on the basis of conditioned rather than primary reinforcers is a pervasive part of modern life, yet we have a remarkably limited understanding of what underlying associative information is triggered by these cues to guide responding. Specifically, it is not certain whether conditioned reinforcers are effective because they evoke representations of specific outcomes or because they trigger general affective states that are independent of any specific outcome. This question has important implications for how different brain circuits might be involved in conditioned reinforcement. Here, we use specialized Pavlovian training procedures, reinforcer devaluation and transreinforcer blocking, to create cues that were biased to preferentially evoke either devaluation-insensitive, general affect representations or, devaluation-sensitive, outcome-specific representations. Subsequently, these cues, along with normally conditioned control cues, were presented contingent on lever pressing. We found that intact rats learned to lever press for either the outcome or the affect cues to the same extent as for a normally conditioned cue. These results demonstrate that conditioned reinforcers can guide responding through either type of associative information. Interestingly, conditioned reinforcement was abolished in rats with basolateral amygdala lesions. Consistent with the extant literature, this result suggests a general role for basolateral amygdala in conditioned reinforcement. The implications of these data, combined with recent reports from our laboratory of a more specialized role of orbitofrontal cortex in conditioned reinforcement, will be discussed.
COnstructing Proxy Records from Age models (COPRA)

Reliable age models are fundamental for any palaeoclimate reconstruction. Available interpolation proce- dures between age control points are often inadequately re- ported, and very few translate age uncertainties to proxy un- certainties. Most available modeling algorithms do not allow incorporation of layer counted intervals to improve the con- fidence limits of the age model in question. We present a framework that allows detection and interac- tive handling of age reversals and hiatuses, depth-age mod- eling, and proxy-record reconstruction. Monte Carlo simula- tion and a translation procedure are used to assign a precise time scale to climate proxies and to translate dating uncer- tainties to uncertainties in the proxy values. The presented framework allows integration of incremental relative dating information to improve the final age model. The free soft- ware package COPRA1.0 facilitates easy interactive usage.
Cortical Signatures of Dyslexia and Remediation: An Intrinsic Functional Connectivity Approach

This observational, cross-sectional study investigates cortical signatures of developmental dyslexia, particularly from the perspective of behavioral remediation. We employed resting-state fMRI, and compared intrinsic functional connectivity (iFC) patterns of known reading regions (seeds) among three dyslexia groups characterized by (a) no remediation (current reading and spelling deficits), (b) partial remediation (only reading deficit remediated), and (c) full remediation (both reading and spelling deficits remediated), and a group of age- and IQ-matched typically developing children (TDC) (total N = 44, age range = 7–15 years). We observed significant group differences in iFC of two seeds located in the left posterior reading network – left intraparietal sulcus (L.IPS) and left fusiform gyrus (L.FFG). Specifically, iFC between L.IPS and left middle frontal gyrus was significantly weaker in all dyslexia groups, irrespective of remediation status/literacy competence, suggesting that persistent dysfunction in the fronto-parietal attention network characterizes dyslexia. Additionally, relative to both TDC and the no remediation group, the remediation groups exhibited stronger iFC between L.FFG and right middle occipital gyrus (R.MOG). The full remediation group also exhibited stronger negative iFC between the same L.FFG seed and right medial prefrontal cortex (R.MPFC), a core region of the default network These results suggest that behavioral remediation may be associated with compensatory changes anchored in L.FFG, which reflect atypically stronger coupling between posterior visual regions (L.FFG-R.MOG) and greater functional segregation between task-positive and task-negative regions (L.FFG-R.MPFC). These findings were bolstered by significant relationships between the strength of the identified functional connections and literacy scores. We conclude that examining iFC can reveal cortical signatures of dyslexia with particular promise for monitoring neural changes associated with behavioral remediation.
Sketch-based Querying of Distributed Sliding-Window Data Streams

While traditional data-management systems focus on evaluating single, ad-hoc queries over static data sets in a centralized setting, several emerging applications require (possibly, continuous) answers to queries on dynamic data that is widely distributed and constantly updated. Furthermore, such query answers often need to discount data that is "stale", and operate solely on a sliding window of recent data arrivals (e.g., data updates occurring over the last 24 hours). Such distributed data streaming applications mandate novel algorithmic solutions that are both time- and space-efficient (to manage high-speed data streams), and also communication-efficient (to deal with physical data distribution). In this paper, we consider the problem of complex query answering over distributed, high-dimensional data streams in the sliding-window model. We introduce a novel sketching technique (termed ECM-sketch) that allows effective summarization of streaming data over both time-based and count-based sliding windows with probabilistic accuracy guarantees. Our sketch structure enables point as well as inner-product queries, and can be employed to address a broad range of problems, such as maintaining frequency statistics, finding heavy hitters, and computing quantiles in the sliding-window model. Focusing on distributed environments, we demonstrate how ECM-sketches of individual, local streams can be composed to generate a (low-error) ECM-sketch summary of the order-preserving aggregation of all streams; furthermore, we show how ECM-sketches can be exploited for continuous monitoring of sliding-window queries over distributed streams. Our extensive experimental study with two real-life data sets validates our theoretical claims and verifies the effectiveness of our techniques. To the best of our knowledge, ours is the first work to address efficient, guaranteed-error complex query answering over distributed data streams in the sliding-window model.
Compulsory Military Service and Personality Development

Compulsory military service is a uniformed life event disrupting the lives of young men (and sometimes women) in countries with conscription. Consequently, the development of personality and subjective well-being during service was investigated using representative population data from the German Socio-Economic Panel. In line with previous findings, men who chose military service revealed descriptively lower agreeableness than those who did civil service (d = –0.33). Contrasting previous research, agreeableness ratings remained stable in both groups. Conscientiousness increased in both groups (η² = .067). The potentially disruptive nature of conscription is not reflected in the present longitudinal results.Overall, personality traits and life satisfaction appear to remain remarkably stable despite the substantial changes of living environments and daily routines associated with military service.
Towards providing effective academic literacy intervention

This article focuses on the current situation in South Africa in which a number of factors related to academic literacy deleteriously affect student throughput. This has large financial implications for the country as well as tertiary institutions. Since significant numbers of students with high academic potential are at risk because of their low levels of academic literacy, all first year students at three South African universities write the Test of Academic Literacy Levels (TALL). This test can be used to assign students to appropriate support courses. An explanation illustrated by empirical data is given of the construct and the use of TALL. Preliminary conclusions in terms of the impact of the intervention are drawn as first iteration towards an in-depth longitudinal study to test the effectiveness/success of the academic literacy intervention. Finally suggestions for further research are outlined.
Heterogeneity in Levels of Vacuolating Cytotoxin Gene (vacA) Transcription among Helicobacter pylori Strains

ABSTRACT Broth culture supernatants from Tox+Helicobacter pylori strains induce vacuolation of HeLa cells in vitro and contain VacA in concentrations that are higher than those found in supernatants from Tox−H. pyloristrains. To investigate the basis for this phenomenon, we analyzed the transcription of the vacuolating cytotoxin gene (vacA) in eight Tox+ strains (each with a type s1/m1 vacA genotype) and nine Tox− strains (each with a type s2/m2 vacA genotype). Most of the Tox+ and Tox− strains tested used the samevacA transcriptional start point, but Tox+strains yielded significantly stronger primer extension signal intensities than did Tox− strains (mean densitometry values of 15.8 ± 1.9 versus 8.9 ± 1.7, P = 0.0016). Correspondingly, when we introducedvacA::xylE transcriptional fusions into the chromosomes of a Tox+ strain (60190) and a Tox− strain (86-313), the level of XylE activity in 60190vacA::xylE was about 30-fold higher than that in 86-313 vacA::xylE. Sequence analysis and promoter exchange experiments indicated that the different levels of vacA transcription in these two strains cannot be explained solely by a difference in promoter strength. These data indicate that Tox+ and Tox−H. pylori strains typically differ not only in the VacA amino acid sequence but also in the level of vacA transcription.
Iron Bioavailability Studied in Infants: The Influence of Phytic Acid and Ascorbic Acid in Infant Formulas Based on Soy Isolate

ABSTRACT: The influence of phytic acid and ascorbic acid content of soy formula on iron (Fe) bioavailability was investigated in infants by analysis of the incorporation of stable isotopes of Fe into red blood cells 14 d after administration using a double stable isotope technique. Paired comparisons were made with each infant acting as his or her own control. The geometric mean fractional Fe incorporation into red blood cells increased from 5.5 to 6.8% (p<0.05) when soy formula with the native content of phytic acid was compared with a 83% dephytinized formula. A more pronounced effect was shown with soy formula containing no phytic acid; the mean fractional Fe incorporation increased from 3.9 (native phytic acid) to 8.7% (zero phytic acid; p < 0.001). A significant (p < 0.01) effect was also demonstrated when the Fe:ascorbic acid molar ratio in the native phytate-containing formula was increased from 1:2.1 to 1:4.2; mean fractional Fe incorporation increased from 5.9 to 9.6%. These results demonstrate that the Fe bioavailability from soy-based infant formulas can be similarly increased by either removing phytic acid or increasing the ascorbic acid content.
Effect of osmotic-release oral system methylphenidate on learning skills in adolescents with attention-deficit/hyperactivity disorder: an open-label study

We evaluated the effect of osmotic-release oral system (OROS) methylphenidate on learning skills in adolescents with attention-deficit/hyperactivity disorder (ADHD). In an open-label study, 121 adolescents with ADHD were administered flexible doses of OROS methylphenidate for 12 weeks. The efficacy of methylphenidate on ADHD symptoms was evaluated by ADHD Rating Scale (ARS) and Clinical Global Impression Scale (CGI). Learning Skills Test (LST) was used to measure the learning skills of the participants at the baseline and the endpoint. Continuous performance test, visuospatial and verbal working memory, verbal fluency, and inhibition were evaluated before and after the 12 weeks of treatment. The mean total and subscores of LST were significantly increased after the 12-week treatment with OROS methylphenidate. Executive functions were also improved during the trial, with the exception of inhibition measured by the Stroop Test. To the best of our knowledge, this is the first study to examine the influence of OROS methylphenidate on learning skill. As a result, OROS methylphenidate was effective in enhancing learning skills in adolescents with ADHD.
Anti-inflammatory Lignans from the Fruits of Acanthopanax sessiliflorus

A new lignan, named acanthosessilin A (1), as well as eight known lignan and lignan glycosides 2−9 were isolated from an ethanolic extract of Acanthopanax sessiliflorus fruits. The chemical structures were determined by spectroscopic methods, including HR-EIMS, 1D NMR (1H, 13C, DEPT), 2D NMR (gCOSY, gHSQC, gHMBC, NOESY), and IR spectroscopy. All isolated compounds were tested for the ability to inhibit LPS-induced nitric oxide production in RAW264.7 macrophages.
Which males or females are most at risk and on what? An analysis of gender differentials within the primary school system of Trinidad and Tobago

This paper reviews the work on gendered achievement in the English‐speaking Caribbean, with its often explicit focus on underachieving males. However, patterns of gendered achievement are more likely region‐specific and variegated in some contexts. In Trinidad and Tobago, the full‐scale implementation of national assessments in 2004 provided an opportunity to evaluate mathematics and language performance across the entire pupil population at standards 1 (7‐ to 8‐year‐olds) and 3 (9‐ to 10‐year‐olds). Census data from the high‐stakes 2003 Secondary Entrance Assessment (SEA) administered at standard 5 (ages: 10–11+) were also included in the analysis. Therefore the entire dataset consisted of 52,284 primary school students (26,574 males and 25,710 females). The findings confirmed that female pupils had a statistically significant advantage on all assessments. However, in terms of practical significance, most differentials were negligible to small. Medium‐sized differentials were obtained for pupils of low ability, living in rural educational districts, and on language arts. Male achievement scores were also more variable for lower grade levels, low ability groups and language arts. Paradoxically, in some educational districts secondary school placement opportunities still favoured males. These variegated patterns of gendered achievement may be associated with differences in institutional effectiveness and variations in male socialization practices that are especially evident across the urban–rural divide.
Hamburger Beiträge zur Angewandten Mathematik Microscopic car-following models revisited : From road works to fundamental diagrams

We analyse the dynamics of the classical optimal velocity model for the case of inhomogeneous drivers and for the case of road works. We introduce a different viewpoint, the so-called rotation solutions, which in case of an additional symmetry leads to the POM solutions. This approach opens the possibility to analytical and numerical bifurcation studies, which show a big variety in the possible dynamics of this very simple model. In addition we mimic different measurement approaches and recover the inverse greek λ structure in the fundamental diagram.
Reverse Multi-Label Learning

Multi-label classification is the task of predicting potentially multiple labels for a given instance. This is common in several applications such as image annotation, document classification and gene function prediction. In this paper we present a formulation for this problem based on reverse prediction: we predict sets of instances given the labels. By viewing the problem from this perspective, the most popular quality measures for assessing the performance of multi-label classification admit relaxations that can be efficiently optimised. We optimise these relaxations with standard algorithms and compare our results with several state-of-the-art methods, showing excellent performance.
Biopsy proven and biopsy negative temporal arteritis: differences in clinical spectrum at the onset of the disease

OBJECTIVES To assess the clinical features of biopsy proven and negative biopsy temporal arteritis at the time of diagnosis and during a three year follow up. METHODS Newly diagnosed cases of giant cell arteritis were included in a prospective, multicentre study. Initial clinical and biological features, season of diagnosis, and cardiovascular events occurring during the follow up were recorded. Biopsy proven and negative biopsy cases were compared. RESULTS Two hundred and seven biopsy proven, and 85 negative biopsy cases were included from 1991 to 1997. Fifty eight per cent of the biopsy proven cases, compared with 39.29% of the negative biopsy cases, were diagnosed during the autumn or winter (p = 0.003). Visual problems (31.5%,v 19.1%, p = 0.031), blindness (9.7%v 2.38%, p = 0.033), jaw claudication (40.8%, v 28.243%, p = 0.044), and temporal artery palpation abnormalities (61.3%v 29.5%, p = 7.10-7) were more frequent in the biopsy proven than in the negative biopsy group. Less specific symptoms, such as headache (82.5%v 92.9%, p = 0.021), or associated polymyalgia rheumatica (40.1% v 65.9%, p = 9 × 10-5) were more prevalent in the negative biopsy cases. Biological markers of inflammation were significantly more increased in the biopsy proven group. All cases of blindness occurring after treatment belonged to the biopsy proven group. CONCLUSION Biopsy proven cases seem to be more severe than biopsy negative cases at the time of diagnosis and during follow up. Seasonal difference at diagnosis may suggest a different aetiological pattern.
Can Mixed-Species Groups Reduce Individual Parasite Load? A Field Test with Two Closely Related Poeciliid Fishes (Poecilia reticulata and Poecilia picta)

Predation and parasitism are two of the most important sources of mortality in nature. By forming groups, individuals can gain protection against predators but may increase their risk of being infected with contagious parasites. Animals might resolve this conflict by forming mixed-species groups thereby reducing the costs associated with parasites through a relative decrease in available hosts. We tested this hypothesis in a system with two closely related poeciliid fishes (Poecilia reticulata and Poecilia picta) and their host-specific monogenean ectoparasites (Gyrodactylus spp.) in Trinidad. Fish from three different rivers were sampled from single and mixed-species groups, measured and scanned for Gyrodactylus. The presence and abundance of Gyrodactylus were lower when fish of both species were part of mixed-species groups relative to single-species groups. This is consistent with the hypothesis that mixed-species groups provide a level of protection against contagious parasites. We discuss the importance of potentially confounding factors such as salinity and individual fish size.
Kinetics of Local Tissue and Regional Lymph Node IL‐2 and IFN‐γ Responses in Experimental Oral Mucosa and Skin Contact Sensitivity in Mice

Using ELISA, we have quantified the levels of IL‐2 and IFN‐γ in the oral mucosa, ear skin and regional and distant lymph nodes in an experimental murine model of contact sensitivity (CS), induced by the hapten oxazolone (OXA). Compared to normal conditions, the levels of IL‐2 peaked early (4–6 h) after hapten exposure in the hapten‐exposed tissues analysed both during the first hapten exposure (sensitization) and the second (elicitation) phase, thereafter quickly to subside. The oral mucosa displayed maximal 24‐fold increase in IL‐2 levels after sensitization and 39‐fold increase after elicitation. Respective figures for ear skin were ×27 and ×35 and for regional lymph nodes ×8 and ×9, respectively. The distant lymph nodes displayed only minor cytokine increases at any time. IFN‐γ‐levels did not increase after sensitization with OXA. An increase in IFN‐γ was seen after the second exposure, peaking at 8–24 h, thereafter quickly subsiding. The oral mucosa IFN‐γ increased ×14 after elicitation, the ear skin ×8 and regional lymph nodes ×37. The weight of the four regional lymph nodes increased from 10 to 38 mg, and the total number of cells in these lymph nodes was increased ×11, peaking 48 h after the elicitation. We conclude that in CS reactions, tissue levels of IL‐2 increased in buccal mucosa, ear skin and in regional lymph nodes after hapten exposure and re‐exposure, IFN‐γ appeared only after re‐exposure to the hapten. The increased weight of the regional lymph nodes was mainly attributed to cell proliferation. The common ectodermal origin and the similarity of the CS reactions on skin and in buccal mucosa indicate that these tissues share common immunological patterns of Th1 cell reactivity, at least in dealing with haptens like OXA.
