and assimilation into the norm. Having introduced masculinity, Chapter 6 provides a more detailed analysis of current debates in the field of men and masculinities through the lens of voice and visibility. The chapter is organized around four existing frameworks from the masculinities literature — role theory, social relations, post-structuralism, and psychoanalytical perspectives—which the authors align with their own four perspectives—surface conceptualisations of voice, surface conceptualisations of visibility and deep conceptualisations of visibility, respectively. The chapter concludes with a table that brings together all eight of these analytical principles to illustrate their differences and commonalities. Chapter 7 applies the framework to the authors’ own work on entrepreneurship. In constructing an analytical framework that both contradicts and overlaps with existing perspectives the authors run the risk of producing a confusing and overlycomplicated text. The main strength of this book lies in the logical and accessible way in which it presents what is indeed challenging material. The voice/visibility framework permits an exploration of relationships, tensions and commonalities between more conventional feminist perspectives and importantly enables the authors to demonstrate how they have been used to shape understanding of gendering of organizations. In this respect it is a welcome addition in the field of gender and organization studies. I would caution, however, that some understanding of feminist perspectives is necessary to fully appreciate the arguments put forward.
Achievement and language proficiency of Latino students in dual language programmes: native English speakers, fluent English/previous ELLs, and current ELLs

Abstract This article examines the language proficiency and achievement outcomes of Latino students enrolled in a dual language programme who varied by language proficiency (Native English speakers, Current English Language Learners – ELLs, Fluent English Proficient/Previous ELLs). Most previous research has not disaggregated Latino students, especially ELLs. The purpose of this research is to examine the achievement and language proficiency of 732 Grade 4 to Grade 8 Latino students enrolled in a dual language programme who differed by language proficiency. Results show that these Latino student groups achieve at higher levels than their peers in English mainstream. Findings also indicated that the three groups vary in parent education, language proficiency in Spanish, and achievement as measured in Spanish and English. Further, Fluent English Proficient/Previous ELLs are the most Spanish proficient and bilingual, achieve at higher levels in English and Spanish, and close the achievement gap with native English speakers in English mainstream programmes.

The Global Extent and Determinants of Savanna and Forest as Alternative Biome States

Savanna and forest are alternative states governed by fire at intermediate rainfall levels. Theoretically, fire–tree cover feedbacks can maintain savanna and forest as alternative stable states. However, the global extent of fire-driven discontinuities in tree cover is unknown, especially accounting for seasonality and soils. We use tree cover, climate, fire, and soils data sets to show that tree cover is globally discontinuous. Climate influences tree cover globally but, at intermediate rainfall (1000 to 2500 millimeters) with mild seasonality (less than 7 months), tree cover is bimodal, and only fire differentiates between savanna and forest. These may be alternative states over large areas, including parts of Amazonia and the Congo. Changes in biome distributions, whether at the cost of savanna (due to fragmentation) or forest (due to climate), will be neither smooth nor easily reversible.
Especialización manufacturera y aglomeración urbana en las grandes ciudades de México

This paper uses the concepts of specialisation and urbanisation economies to study the growth of employment in the manufacturing sector in the largest cities of Mexico. We observe a relative decrease in the concentration of industries in the center of the country and a more dynamical increase in the cities of the north of Mexico. We applied three econometric models to estimate the effect of specialisation and urbanisation economies in the main urban areas of Mexico. The results reveal that specialisation economies have had a positive effect in the employment growth. In the areas where manufacturing is more important (Mexico City, Monterrey and Guadalajara) the size of the labour market was a very important factor. Whereas in the case of urbanisation economies, they had a positive but not conclusive effect in the employment growth.
Task Characteristics and the Experience of Optimal Flow in Human—Computer Interaction

Abstract This article builds on job characteristics and optimal flow theory to describe the experience of individuals using computers in the workplace. A model was developed and tested with linear structural relationship modeling (LISREL) with data from 149 professionals employed in a variety of organizations. Flow, which is characterized by intense concentration and enjoyment, was found to be significantly linked with exploratory use behavior, which in turn was linked to extent of computer use. Flow was itself determined by the individual's sense of being in control and the level of challenge perceived in using computers. Perceived control was more important for individuals with high task-scope jobs, that is, jobs with high variety, identity, autonomy, and feedback. Challenge played a greater role for low task-scope individuals. Practical and theoretical implications of the model are discussed, and suggestions for further research are offered.
Dehydroepiandrosterone antagonizes the suppressive effects of dexamethasone on lymphocyte proliferation.

Administration of dehydroepiandrosterone (DHEA) appears to have physiological effects opposing those of glucocorticoids in several animal models. Recently, immunomodulatory effects of treatment with DHEA have been described. This paper reports the effects of DHEA treatment on splenocyte blastogenic responses as well as thymic and spleen weights in C3H/HeN mice. Pretreatment of mice with sc DHEA (60 mg/kg.day) for 3 days in vivo antagonized the profound suppression of in vitro blastogenic responses seen in T- and B-lymphocytes after a single injection of dexamethasone (DEX; 60 mg/kg). Pretreatment with DHEA also significantly reduced dexamethasone-induced thymic and splenic atrophy. Splenic lymphocytes from DHEA-treated mice were markedly more resistant to in in vitro suppression of blastogenesis by DEX at 10(-6)-10(-8) M compared to lymphocytes from control mice. However, DHEA added to lymphocyte cultures in vitro over a concentration range from 10(-7)-10(-8) M failed to protect against suppression of mitogenic responses caused by addition of DEX to cultures. In summary, DHEA given in vivo antagonizes the suppressive actions of DEX on lymphoid target tissues in mice.
Genome-Wide Identification of Genes Conferring Energy Related Resistance to a Synthetic Antimicrobial Peptide (Bac8c)

A fundamental issue in the design and development of antimicrobials is the lack of understanding of complex modes of action and how this complexity affects potential pathways for resistance evolution. Bac8c (RIWVIWRR-NH2) is an 8 amino acid antimicrobial peptide (AMP) that has been shown to have enhanced activity against a range of pathogenic Gram-positive and Gram-negative bacteria, as well as yeast. We have previously demonstrated that Bac8c appears to interfere with multiple targets, at least in part through the disruption of cytoplasmic membrane related functions, and that resistance to this peptide does not easily develop using standard laboratory methods. Here, we applied a genomics approach, SCalar Analysis of Library Enrichement (SCALEs), to map the effect of gene overexpression onto Bac8c resistance in parallel for all genes and gene combinations (up to ∼ 10 adjacent genes) in the E. coli genome (a total of ∼ 500,000 individual clones were mapped). Our efforts identified an elaborate network of genes for which overexpression leads to low-level resistance to Bac8c (including biofilm formation, multi-drug transporters, etc). This data was analyzed to provide insights into the complex relationships between mechanisms of action and potential routes by which resistance to this synthetic AMP can develop.
Application: Functional ASL, Pharma Perfusion MRI & Reactivity Measurements

1. Introduction An important feature of brain perfusion is that it can adjust itself based on tissue demand and others conditions. This property is to some extent more clinically relevant compared to baseline perfusion only, because deficits in many brain disorders are often most pronounced when the brain is asked to perform a demanding task. Therefore, perfusion techniques are sometimes used in a dynamic manner in which brain perfusion is measured under two or more different physiologic conditions, from which the capacity of blood supply regulation is evaluated. In this lecture, applications related to dynamic measurement of perfusion are discussed.
On the cooperation between cognitive radio users and femtocell networks for cooperative spectrum sensing and self-organization

We propose a single framework for cooperative spectrum sensing of cognitive radio network as well as for the self-organization of femtocells. This constructs a large-scale spectrum database through cooperative spectrum sensing for cognitive radio network, which exploits the existing infrastructure of the two-tier (macrocell-femtocell) network and encourages a small cellular network, i.e., femtocell, to act as the rendezvous point between individual local spectrum monitors and the fusion center of spectrum database. Distributed sensing results reported from many cognitive radio users can be integrated into spectrum database via these rendezvous points. Thus the problem of the dependency of conventional cooperative spectrum sensing on common control channel is improved. Meanwhile, the interaction between cognitive radio users and femtocells can offer an intriguing possibility to improve the self-organization of femtocells by absorbing radio environment maps constructed by cognitive radio users. Game theory can be applied to formulate the mutual benefits in the cooperation between cognitive radio user and femtocell. We illustrate the numerical effects of the coalitions between cognitive radio users and femtocells.
An XOR based Reed-Solomon algorithm for advanced RAID systems

In this paper, a simple codec algorithm, based on Reed-Solomon (RS) codes, is proposed for erasure correcting in RAID (redundant array of independent disks) level 6 systems. Unlike conventional RS codes, this scheme, with a mathematical reduction method, called reduced static-checksum table approach, could improve coding performance, including encoding and decoding procedures. This scheme uses current industrial RAID-5 controllers as well as the regular hardware, and is without extra cost in adding any new equipment. Moreover, our algorithm is able to expand to correct multiple failed-disks while others, EvenOdd codes for example, cannot do so. Also, this scheme performs all computations with only simple exclusive-OR (XOR) operators, the same as EvenOdd codes. For most RAID architectures, this new XOR-based RS code could adapt to implementation in terms of reliability, flexibility and lower cost.
Learning Teams and Virtual Communities of Practice: Managing Evidence and Expertise Beyond the Stable State

In the past decade, the Israeli Ministry of Social Affairs has been engaged in an ongoing effort to change the capacity of social service organizations and social workers across the country to use and create knowledge in order to achieve the best outcomes for the people they serve. Although there is an ever-growing mandate in Israel to demonstrate outcomes and use effective strategies, social workers have historically experienced unique challenges in accessing and assessing available evidence-based practice when they are available. The first step to addressing these challenges, the intra-organizational phase, was to design, implement, and test a model of organizational learning designed to teach social workers how to use learning to change practice. The second step, the inter-organizational phase, was the introduction of virtual communities of practice as a tool to support workers in the acquisition and dissemination of new knowledge. This paper presents a case study of this effort including a description of the development and implementation of the two phases and an agenda for future research.
An integrated approach for studying architectural evolution

Studying how a software system has evolved over time is difficult, time consuming, and costly; existing techniques are often limited in their applicability, are hard to extend, and provide little support for coping with architectural change. The paper introduces an approach to studying software evolution that integrates the use of metrics, software visualization, and origin analysis, which is a set of techniques for reasoning about structural and architectural change. Our approach incorporates data from various statistical and metrics tools, and provides a query engine as well as a Web-based visualization and navigation interface. It aims to provide an extensible, integrated environment for aiding software maintainers in understanding the evolution of long-lived systems that have undergone significant architectural change. We use the evolution of GCC as an example to demonstrate the uses of various functionalities of BEAGLE, a prototype implementation of the proposed environment.
iTRAQ-Based Quantitative Proteomic Analysis of Cotton Roots and Leaves Reveals Pathways Associated with Salt Stress

Salinity is a major abiotic stress that affects plant growth and development. In this study, we performed a proteomic analysis of cotton roots and leaf tissue following exposure to saline stress. 611 and 1477 proteins were differentially expressed in the roots and leaves, respectively. In the roots, 259 (42%) proteins were up-regulated and 352 (58%) were down-regulated. In the leaves, 748 (51%) proteins were up-regulated and 729 (49%) were down-regulated. On the basis of Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis, we concluded that the phenylalanine metabolism and starch and sucrose metabolism were active for energy homeostasis to cope with salt stress in cotton roots. Moreover, photosynthesis, pyruvate metabolism, glycolysis / gluconeogenesis, carbon fixation in photosynthetic organisms and phenylalanine metabolism were inhabited to reduce energy consumption. Characterization of the signaling pathways will help elucidate the mechanism activated by cotton in response to salt stress.
Abundance and Distribution of Enteric Bacteria and Viruses in Coastal and Estuarine Sediments—a Review

The long term survival of fecal indicator organisms (FIOs) and human pathogenic microorganisms in sediments is important from a water quality, human health and ecological perspective. Typically, both bacteria and viruses strongly associate with particulate matter present in freshwater, estuarine and marine environments. This association tends to be stronger in finer textured sediments and is strongly influenced by the type and quantity of clay minerals and organic matter present. Binding to particle surfaces promotes the persistence of bacteria in the environment by offering physical and chemical protection from biotic and abiotic stresses. How bacterial and viral viability and pathogenicity is influenced by surface attachment requires further study. Typically, long-term association with surfaces including sediments induces bacteria to enter a viable-but-non-culturable (VBNC) state. Inherent methodological challenges of quantifying VBNC bacteria may lead to the frequent under-reporting of their abundance in sediments. The implications of this in a quantitative risk assessment context remain unclear. Similarly, sediments can harbor significant amounts of enteric viruses, however, the factors regulating their persistence remains poorly understood. Quantification of viruses in sediment remains problematic due to our poor ability to recover intact viral particles from sediment surfaces (typically <10%), our inability to distinguish between infective and damaged (non-infective) viral particles, aggregation of viral particles, and inhibition during qPCR. This suggests that the true viral titre in sediments may be being vastly underestimated. In turn, this is limiting our ability to understand the fate and transport of viruses in sediments. Model systems (e.g., human cell culture) are also lacking for some key viruses, preventing our ability to evaluate the infectivity of viruses recovered from sediments (e.g., norovirus). The release of particle-bound bacteria and viruses into the water column during sediment resuspension also represents a risk to water quality. In conclusion, our poor process level understanding of viral/bacterial-sediment interactions combined with methodological challenges is limiting the accurate source apportionment and quantitative microbial risk assessment for pathogenic organisms associated with sediments in aquatic environments.
On Applying Sonification Methods to Convey Business Process Data

Visualization of business process models with large numbers of process activities and running instances in different execution states shows various limitations. Hence, using sonification methods becomes a promising idea to enable users to gain insight into process information that cannot be conveyed by using purely visual means. This visionary short paper aims to envision the usage of sonification methods in order to represent business process-related data in all phases of the process life cycle. Sonification methods are presented and analyzed in terms of their potential suitability for representations of process data. Overall, this paper aims at breaking new ground for designing and applying multimodal approaches for making process information more accessible to users.
Combining Event Processing and Support Vector Machines for Automated Flight Diversion Predictions

Multi-modal logistics chains are those transportation processes in which different modes of transportation are involved for the delivery of goods. These modes are adopted in consecutive legs, which have to be synchronized. An example scenario is the delivery of goods from a production center in New York, USA, to a plant in Utrecht, the Netherlands. The transportation chain consists of two legs: (i) an aicraft carries the goods from John F. Kennedy International Airport (New York) to Schiphol (Amsterdam) and (ii) a truck sent by a Logistics Service Provider (LSP) transports the cargo from Dutch airport to Utrecht. The growth in international and inter-continental trade has led to a significant increase of multi-modal transports worldwide. Therefore, guaranteeing its efficiency is of crucial relevance for the successful completion of such transportation processes. In the example scenario, the goal of the LSP is to deliver the goods in time, in conformance with the Service Level Objectives (SLOs).
Targeting human PPN: few patients, numerous disputes

Sir, Dr Yelnik highlights an important issue, already extensively addressed (consider Mazzone et al ., 2007 a , b in response to Zrinzo and co-authors). Briefly, there is no doubt that some figures were misleading (Stefani et al ., 2007). In describing our original approach to the first six Parkinson's disease (PD) patients double-implanted in the subthalamic nucleus (STN) plus the pedunculopontine nucleus (PPN), we have emphasized the trajectory through …
Technology, Size, and Organization Structure

A study of 82 business organizations provides data on the disputed question of whether organization technology or organization size is more closely associated with the elements of organization structure. Technological variables are found to be associated with structure in certain definable respects, but, on the whole, size enjoys a much higher relationship. Partial correlational analysis serves to clarify these patterns of association. Measures of technology used in previous studies are seen to be problematic for two reasons. They can obscure the differential elements involved in technology. Secondly, they may to an important degree be acting as surrogates for inter-industry differences which include the influence of industrial managerial ideologies and environments.
Constant mean curvature hypersurfaces condensing along a submanifold

Given any nondegenerate k-dimensional minimal submanifold K of codimension greater than 1, we prove the existence of families of constant mean curvature submanifolds, with mean curvature varying from one member of the family to another, which `condense' to K. In particular, our result proves the existence of constant mean curvature hypersurfaces with nontrivial topology in any Riemannian manifold.
Self-stabilizing systems in spite of distributed control

The synchronization task between loosely coupled cyclic sequential processes (as can be distinguished in, for instance, operating systems) can be viewed as keeping the relation “the system is in a legitimate state” invariant. As a result, each individual process step that could possibly cause violation of that relation has to be preceded by a test deciding whether the process in question is allowed to proceed or has to be delayed. The resulting design is readily—and quite systematically—implemented if the different processes can be granted mutually exclusive access to a common store in which “the current system state” is recorded.
Models of the Creative Process: Past, Present and Future

The creative process, one of the key topics discussed in Guilford's (1950) address to the American Psychological Association and his subsequent work, refers to the sequence of thoughts and actions that leads to novel, adaptive productions. This article examines conceptions of the creative process that have been advocated during the past century. In particular, stage-based models of the creative process are discussed and the evolution of these models is traced. Empirical research suggests that the basic 4-stage model of the creative process may need to be revised or replaced. Several key questions about the creative process are raised, such as how the creative process differs from the noncreative process and how process-related differences may lead to different levels of creative performance. New directions for future research are identified.
