Enhanced proliferation of progenitor cells in the subventricular zone and limited neuronal production in the striatum and neocortex of adult macaque monkeys after global cerebral ischemia

Cerebral ischemia in adult rodent models increases the proliferation of endogenous neural progenitor cells residing in the subventricular zone along the anterior horn of the lateral ventricle (SVZa) and induces neurogenesis in the postischemic striatum and cortex. Whether the adult primate brain preserves a similar ability in response to an ischemic insult is uncertain. We used the DNA synthesis indicator bromodeoxyuridine (BrdU) to label newly generated cells in adult macaque monkeys and show here that the proliferation of cells with a progenitor phenotype (double positive for BrdU and the markers Musashi1, Nestin, and βIII‐tubulin) in SVZa increased during the second week after a 20‐min transient global brain ischemia. Subsequent progenitor migration seemed restricted to the rostral migratory stream toward the olfactory bulb and ischemia increased the proportion of adult‐generated cells retaining their location in SVZa with a progenitor phenotype. Despite the lack of evidence for progenitor cell migration toward the postischemic striatum or prefrontal neocortex, a small but sustained proportion of BrdU‐labeled cells expressed features of postmitotic neurons (positive for the protein NeuN and the transcription factors Tbr1 and Islet1) in these two regions for at least 79 days after ischemia. Taken together, our data suggest an enhanced neurogenic response in the adult primate telencephalon after a cerebral ischemic insult. © 2005 Wiley‐Liss, Inc.
Negotiating Intersecting Minority Identities: The Cultural Transitioning of Jewish Argentinean Immigrants

This phenomenological qualitative study employed relational cultural theory and feminist social constructionist theory as epistemologies to examine the role of multiple intersecting identities in the cultural transitioning of Jewish Argentinean immigrants into a range of relational and social contexts. Results indicated that identity salience across different relational contexts was strongly influenced by the emergence of the immigrant identity and the resulting interpersonal challenges. Implications for future research and counselling are discussed.
ESTIMATES-Implications for property performance measurement

All nationwide return indices for direct owned property are based on valuations, which give a discussion of how well market value estimates reflect transaction prices and market movements. Two valuation experiments in relation to the Swedish Property Index give indications about the magnitude of the variation in estimated market values as well as variation in individual discounted cash flow parameters. The variation in market value estimates is found to be much dependent on the special market situation with fast escalating rents in Stockholm CBD. The results from the two experiments are discussed in relation to the variation found in other studies. One main conclusion is that valuation based performance measurement should be on an aggregated level and that several performance measures should be used for decision making. A challenge for further research is to develop tools that explicit expresses risk exposure.
Generating Functionals of Random Packing Point Processes: From Hard-Core to Carrier Sensing

In this paper we study the generating functionals of several random packing processes: the classical Matern hard-core model; its extensions, the k-Matern models and the ∞-Matern model, which is an example of random sequential packing process. We first give a sufficient condition for the ∞-Matern model to be well-defined (unlike the other two, the latter may not be well-defined on unbounded spaces). Then the generating functional of the resulting point process is given for each of the three models as the solution of a differential equation. Series representations and bounds on the generating functional of the packing models are also derived. Last but not least, we obtain moment measures and Palm distributions of the considered packing models departing from their generating functionals.
Parental Stress in Parents of Children with Learning Disabilities: A Limited Demographic Factors

The main purpose of this study was to examine the level of stress among the parents of children with learning disabilities (LD children). The data were obtained from a survey using the Perceived Stress Scale that involves 264 parents. The results revealed that a total of 99 (37.6%) parents experiencing stress at low level (M = 1.00 – 2.33) and they were in the state of normal. Whilst 138 (52.3%) of the parents were suffering moderate level of stress (M = 2.34 – 3.66) which is considered as mild. Furthermore, the analysis indicated that only 27 (10.1%) of them experienced high level of stress (M = 3.67 – 5.00) which is classified as severe. The findings indicated that mothers of LD children was associated with higher stress and were significantly experienced more stress than fathers. In terms of ethnicity, the findings showed that Chinese parents are experiencing more stress than the Malay and Indian parents. Accordingly, parents of high SES were reported experiencing greater stress than parents of middle and low SES. In contrast to the findings on parents of different religious groups whereby they were at moderate level of stress and the result also showed that there is no significant difference between the Muslims, Christians, Buddhists and Hindus with regard to parenting stress.

Narrating the accumulation of dispossession: Stories of Aboriginal Elders

The lifeworld’s of Aboriginal people and relationships between Aboriginal and non-Aboriginal people in Australia continue to bear the scars of a colonial past and present. Liberation oriented approaches within psychology have emphasised the role of storytelling and the recovery of historical memory in affirming identity and belonging but also for disrupting wilful ignorance of a history of dispossession in order to transform relationships. In this paper we draw on stories shared as part of an oral history based project and in conversational interviews, to explore the ways in which Aboriginal people have understood oppression in their lives, past and present. Following data analyses, three community narratives were identified that collectively narrated the history, legacy, and continuity of colonial dispossession. These stories are important in showing up the circuits and consequences of dispossession and privilege and can be mobilised to challenge dominant cultural narratives that construct Aboriginal people as needing to move on. As the recovery of historical memory, these symbolic resources also serve to strengthen identity and belonging within Aboriginal communities, thus disrupting the internalisation of oppression.
Gender Gaps in Cognitive and Non-Cognitive Skills in Early Primary Grades: Evidence from Rural Indonesia

This paper examines gender gaps in cognitive and non-cognitive skills among a sample of more than 10,000 children between the ages of 6 and 9 in rural Indonesia. In terms of cognitive skills, the analysis finds evidence of gender gaps favoring girls at each age in test scores of language (0.158-0.252 standard deviations) and mathematics (0.155-0.243 standard deviations) in the early years of primary school. Girls also perform significantly better than boys in non-cognitive skills, with higher scores on the social competence (0.086-0.247 standard deviations) and emotional maturity domains (0.213-0.296 standard deviations) of the Early Development Instrument, a finding consistent with research from high-income countries. Decomposition analyses are used to investigate the extent to which enrollment patterns in preschool and primary school as well as parenting practices contribute to these gender gaps in cognitive and non-cognitive skills. Standard decomposition approaches are extended to correct for selection on observables. The findings show that gender differences in enrollment patterns play a role in explaining gender gaps in test scores, while differences in parenting practices do not. However, the relative contribution of observed factors to gender gaps depends on the available quality of preschool services in the child’s village and whether the outcome of interest is cognitive or non-cognitive skills.
The Mass Function of an X-Ray Flux-limited Sample of Galaxy Clusters

A new X-ray-selected and X-ray flux-limited galaxy cluster sample is presented. Based on the ROSAT All-Sky Survey, the 63 brightest clusters with galactic latitude |bII| ≥ 20° and flux fX(0.1-2.4keV) ≥ 2 × 10-11ergss-1cm-2 have been compiled. Gravitational masses have been determined utilizing intracluster gas density profiles, derived mainly from ROSAT PSPC pointed observations, and gas temperatures, as published mainly from ASCA observations, assuming hydrostatic equilibrium. This sample and an extended sample of 106 galaxy clusters is used to establish the X-ray luminosity-gravitational mass relation. From the complete sample the galaxy cluster mass function is determined and used to constrain the mean cosmic matter density and the amplitude of mass fluctuations. Comparison to Press-Schechter type model mass functions in the framework of cold dark matter cosmological models and a Harrison-Zeldovich initial density fluctuation spectrum yields the constraints Ωm = 0.12 and σ8 = 0.96 (90% c.l.). Various possible systematic uncertainties are quantified. Adding all identified systematic uncertainties to the statistical uncertainty in a worst-case fashion results in an upper limit Ωm < 0.31. For comparison to previous results a relation σ8 = 0. 43Ω is derived. The mass function is integrated to show that the contribution of mass bound within virialized cluster regions to the total matter density is small; i.e., Ωcluster = 0.012 for cluster masses larger than 6.4 × 1013 h M☉.
Actual and Perceptual Social Inequality under Transformative Change in Russia and China

Abstract This essay aims at comparing social inequality in Russia and China and how it is perceived by the urban population. The study from which evidence is drawn was conducted through a common methodology of representative surveys of the adult population in two big cities—Shanghai and St Petersburg. The investigation shows that although people in Russia and China have broadly egalitarian attitudes, there are significant differences in the way in which Russians and Chinese regard the current system of distribution. Attitudes to social inequality are much more complicated than a direct link with the objective social situation would suggest. Egalitarian attitudes are connected not only with the actual incomes but they are very powerfully affected by subjective assessments of the distributive system. The essay argues that behind a tendency towards the convergence of political regimes in the two countries at the present time there are different patterns of legitimacy based not only on economic achievement but also on the attitudes of the population, which the ruling elites use in seeking to strengthen their monopoly.
Poverty and livelihoods: whose reality counts?

This paper explores how professionals’ universal, reductionist and standardized views of poverty differ from those of the poor themselves. Poverty line thinking concerned with income-poverty and employment thinking concerned with jobs, project Northern concerns on the South, where the realities of the poor are local, diverse, often complex and dynamic. Examples illustrate how poor people’s criteria differ from those assumed for them by professionals. The paper also discusses neglected dimensions of deprivation including vulnerability, seasonality, powerlessness and humiliation. In the new understandings of poverty, wealth as an objective is replaced by wellbeing and “employment” in jobs by livelihood. The final sections argue for altruism and reversals to enable poor people to analyze and articulate their own needs, and they conclude with the implications for policy and practice of putting first the priorities of the poor.
Attitudes of secondary school pupils towards the teaching and learning of science: a Zimbabwean case

The study sought to investigate the attitudes of Zimbabwean secondary school pupils towards the teaching and learning of science. A randomized sample of 243 participants from eight (8) selected schools completed a 5 point Likert type scale. Factorial Analysis using principal components with Varimax Rotation, Kaiser Normalisation and Scree testing were used to determine validity of the scale. Variables with factor loading of 0.3 and above and Eigen values of 1 and above were considered to form main Attitude towards Science (ATS) scale. Data were analyzed using ANOVA and One way ANOVA. It was found out that pupils in lower classes (Forms 1 and 2) recorded a positive attitude towards science than pupils in the upper classes (Forms 3 and 4). There may be a need to re-examine the reasons why attitude declines with form level. Further studies may look at linkage between pupilâ€™s attitude with their science performance in class, career aspirations and perceptions of the world of science at work.
Decidable Analysis for a Class of Cryptographic Group Protocols with Unbounded Lists

Cryptographic protocols are crucial for securing electronic transactions. The confidence in these protocols can be increased by the formal analysis of their security properties. Although many works have been dedicated to standard protocols like Needham-Schroeder very few address the more challenging class of group protocols. We have introduced in previous work a synchronous model for group protocols, that generalizes standard protocol models by permitting unbounded lists inside messages. This approach also applies to analyzing Web Services manipulating sequences of items.In this model we propose now a decision procedure for the sub-class of Well-Tagged protocols with Autonomous Keys.
Adaptive Detection for Group-Based Multimedia Fingerprinting

Grouping strategy has been proposed recently to leverage the prior knowledge on collusion pattern to improve collusion resistance in multimedia fingerprinting. However, the improvement is not consistent, as reduced performance of the existing group-based fingerprinting schemes than the non-grouped ones is observed when the grouping does not match the true collusion pattern well. In this letter, we propose a new adaptive detection method, where the threshold for the group detection can be adjusted automatically according to the detection statistics that reflect the underlying collusion pattern. Experimental results show that the proposed adaptive detection outperforms nonadaptive detection and provides consistent performance improvement over non-grouped orthogonal fingerprinting schemes under various collusion scenarios.
LOW STELLAR OBLIQUITIES IN COMPACT MULTIPLANET SYSTEMS

We measure the sky-projected stellar obliquities (λ) in the multiple-transiting planetary systems KOI-94 and Kepler-25, using the Rossiter–McLaughlin effect. In both cases, the host stars are well aligned with the orbital planes of the planets. For KOI-94 we find λ = −11° ± 11°, confirming a recent result by Hirano and coworkers. Kepler-25 was a more challenging case, because the transit depth is unusually small (0.13%). To obtain the obliquity, it was necessary to use prior knowledge of the star's projected rotation rate and apply two different analysis methods to independent wavelength regions of the spectra. The two methods gave consistent results, λ = 7° ± 8° and −0. °5 ± 5. °7. There are now a total of five obliquity measurements for host stars of systems of multiple-transiting planets, all of which are consistent with spin-orbit alignment. This alignment is unlikely to be the result of tidal interactions because of the relatively large orbital distances and low planetary masses in the systems. In this respect, the multiplanet host stars differ from hot-Jupiter host stars, which commonly have large spin-orbit misalignments whenever tidal interactions are weak. In particular, the weak-tide subset of hot-Jupiter hosts has obliquities consistent with an isotropic distribution (p = 0.6), but the multiplanet hosts are incompatible with such a distribution (p ∼ 10−6). This suggests that high obliquities are confined to hot-Jupiter systems, and provides further evidence that hot-Jupiter formation involves processes that tilt the planetary orbit.
Unclear fever 7 weeks after renal transplantation in a 56-year-old patient.

A 56-year-old male patient with end-stage renal disease, due to focal sclerotic segmental glomerulonephritis, underwent renal cadaveric transplantation after 2 years of haemodialysis (full-house HLA-match, donor age 48 years, donor and recipient cytomegalovirus (CMV) negative, cold ischaemia time 16h). Due to initial graft non-function, alternate-day haemodialysis was continued for the following 3 weeks until the kidney function gradually improved. The immunosuppressive treatment consisted of prednisone, ciclosporin and mycophenolate mofetil. Five weeks after transplantation, pp65-antigenaemia was detected. Although clinical symptoms were absent, daily treatment with 150mg gancyclovir p.o. over 3 weeks was initiated. The pp65-antigenaemia disappeared. In the seventh week post-transplant, the patient presented with fever (38.78C), an elevated white blood cell count (12.0G/l) (normal range 4.3–10.0) and an increased C-reactive protein (CRP) level (162mg/l) (normal range <5). Microbiological testing revealed Stenotrophomonas maltophilia in cultures obtained from the surgical site. Under treatment with 250mg levofloxacin p.o. per day, laboratory signs of inflammation persisted. Since a thorough diagnostic work-up for the underlying infection did not lead to a sufficient diagnosis, an inflammation scintigraphy with Tc-labelled antineutrophilic antibodies was performed 12 weeks after transplantation. The scan revealed accumulation of granulocytes in the left lobe of the thyroid gland. At physical examination the thyroid gland was slightly enlarged and indolent. Ultrasonography showed multiple liquid abscess formations (Figure 1). Fine needle aspirates yielded Aspergillus fumigatus hyphae. Neither clinical examination nor chest radiography or magnetic resonance imaging exhibited signs of disseminated Aspergillus infection. Aspergillus antigenaemia could not be detected by serological ELISA-screening for galactomannan antigen. The triple immunosuppressive treatment with ciclosporin, mycophenolate mofetil and prednisone was discontinued and replaced by prednisone monotherapy for the following 3 months. Antifungal treatment with caspofungin was initiated. After an initial reduction of the inflammatory parameters however, the CRP level stabilized at above 60mg/l at week 19, and repeated fine needle aspirates of the thyroid gland were still positive for Aspergillus. After voriconazole was added to caspofungin, the sonographic findings improved and inflammatory parameters normalized. On the day of discharge, 6 months after transplantation and 3 months after the development of the mycotic thyroiditis, fine needle aspirates of the left thyroid lobe still revealed minor growth of Aspergillus. However, CRP had dropped to a level <5mg/l. After discharge, the treatment with voriconazole was continued for the following 4 months until subsequent aspirations became negative at month 10. After discharge, mycophenolate mofetil was included in a daily dosage of 1000mg and prednisone was reduced.
Issues About Color, Human Movement, and Number of Responses in the Zulliger Test

Abstract. This study aimed to verify the scope and limitations of the stimuli of indicators of Color (C), Human movement (M), and Response number (R) of the Zulliger test through a qualitative analysis of the stimuli present in the Zulliger and the Rorschach, comparisons in expressions of C, M, and R, and R relations with evaluative inconsistencies on Zulliger. Taking the Rorschach as a reference, the qualitative analysis indicated a variation from little equivalence up to an overrepresentativeness of Zulliger stimuli. The comparisons, made with a sample of 51 subjects tested with the Zulliger and Rorschach tests and divided into concordant and discordant groups according to the evaluation of instruments, revealed a significant decrease of C and M for the Zulliger. We also identified a tendency toward a decrease of R on Zulliger for the discordant group. The results reveal distinctions between the instruments, limitations of the Zulliger, and instigate investigations for the R-Optimized Administration.
Some simple observations on lattice codes

In this paper we are considering product distance of lattice codes. We first remark that the general bounds given for the product distance of real lattice codes in coding theory literature are not the best possible. We then consider product distance bounds of rotated Zn and Z[i]n lattices and show that the simple and general bound can be applied here and that this bound is better than the previously used number theoretic bound in most cases. This analysis also proves that when n grows the orthogonality of Zn and Z[i]n lattices does bound the achievable product distance strongly. Our simple observation proves the surprising result that when n is a power of two the existing rotated Z[i]n lattices are already the best possible. In the last section we concentrate on the block fading channel, or what is equivalent to the slow fading parallel channel, and give few new examples of DMT achieving coding schemes and compare the s-product distance of these to one known coding scheme.
VSR sort: A novel vectorised sorting algorithm & architecture extensions for future microprocessors

Sorting is a widely studied problem in computer science and an elementary building block in many of its subfields. There are several known techniques to vectorise and accelerate a handful of sorting algorithms by using single instruction-multiple data (SIMD) instructions. It is expected that the widths and capabilities of SIMD support will improve dramatically in future microprocessor generations and it is not yet clear whether or not these sorting algorithms will be suitable or optimal when executed on them. This work extrapolates the level of SIMD support in future microprocessors and evaluates these algorithms using a simulation framework. The scalability, strengths and weaknesses of each algorithm are experimentally derived. We then propose VSR sort, our own novel vectorised non-comparative sorting algorithm based on radix sort. To facilitate the execution of this algorithm we define two new SIMD instructions and propose a complementary hardware structure for their execution. Our results show that VSR sort has maximum speedups between 14.9x and 20.6x over a scalar baseline and an average speedup of 3.4x over the next-best vectorised sorting algorithm.
Synchronous collaboration competencies in web‐conferencing environments – their impact on the learning process

Based on a three‐semester design‐based research study examining learning and teaching in a web‐conferencing environment, this article identifies types of synchronous collaboration competencies and reveals their influence on learning processes. Four levels of online collaborative competencies were observed – operational, interactional, managerial, and design. The relative importance of students and teachers possessing the different levels of competencies depended on the degree of interactivity in the learning designs being applied. Both misunderstandings and misuses impacted on learning and collaborative processes, with misuses occurring more persistently throughout semesters than misunderstandings. The distinction between developing students’ technical skills and their collaborative capabilities is drawn. Strategies for developing each are recommended.
