Cloud Computing Ecosystem Model: Refinement and Evaluation

A business ecosystem has evolved in the field of cloud computing whereby new types of market actors have emerged breaking up the traditional value chain of IT service provision. In order to create a profound understanding of this ecosystem, several scholars tried to capture it in a model. However, these models differ considerably from each other. The goal of this paper, therefore, is to develop a revised and comprehensive cloud computing ecosystem model according to the design science paradigm. For this purpose, the recently published Passau Cloud Computing Ecosystem Model (PaCE Model) is developed significantly further by integrating the insights of an analysis of the existing cloud ecosystem models regarding ten criteria and by considering findings from the general cloud and business ecosystem literature. To ensure the integrity of the enhanced PaCE Model, the Internet is manually searched for companies occupying the roles of the model. As a result, the model comprises 26 roles and includes the basic service flows. Since the missing market transparency is regarded as one of the main reasons for the low cloud adoption, the intended contribution is to foster a better understanding of the cloud ecosystem and to provide a conceptual framework for further research.
The Mouse Follicle Microenvironment Regulates Antrum Formation and Steroid Production: Alterations in Gene Expression Profiles1

Abstract Folliculogenesis is a coordinated process, and the genes that regulate development are difficult to investigate in vivo. In vitro culture systems permit the assessment of individual follicles during development, thereby enabling gene expression patterns to be monitored during follicle development. Mouse multilayered secondary follicles (150–180 μm in diameter) were cultured in three-dimensional matrices of varying physical properties for up to 8 days. During this period of follicle growth in vitro, antrum formation and steroid production were monitored, and mRNA was isolated. The expression levels of genes (Star, Cyp11a1, Cyp17a1, Hsd3b1, Cyp19a1, Fshr, Lhcgr, Aqp7, Aqp8, Aqp9, and Hif1a) were measured and correlated to follicle developmental status. Follicles that developed an antrum and produced appropriate levels of estrogen and progesterone had unchanging expression of Star, Aqp7, Aqp8, and Hif1a and a 34-fold increase in Cyp19a1 expression at Day 8 of culture and had elevated Lhcgr at Days 6 and 8 of culture. Follicles that were healthy but did not form an antrum or produce appropriate levels of steroids, however, demonstrated increasing levels of Star, Aqp7, Aqp8, and Hif1a and a 15-fold increase in Cyp19a1 at Day 8 of culture, and Lhcgr levels were not elevated until Day 8 of culture. To our knowledge, this study provides the first temporal analysis of gene expression using individual culture in alginate hydrogels that correlates growth and steroidogenesis during follicle development and identifies expression patterns in healthy follicles and in developmentally disadvantaged follicles.
Effects of Alcohol On Scientific Thought During the Incubation Phase of The Creative Process

The present study examined whether or not acute alcohol intoxication inhibits or facilitates the incubation phase of Wallas' (1926/1970) four-stage model of creativity. Sixty male and female participants were randomly assigned to three groups of equal size: a Control group, a Placebo group and an Alcohol group (alcohol dose: 1.0 ml of 100% alcohol/kg body weight, delivered on two occasions). It was shown that the Alcohol group produced significantly more incubations and significantly higher levels of originality. No differences between groups regarding the scientific value of the products were obtained. Possible consequences of alcohol intoxication for creative production are discussed and a theoretical framework is introduced.
“Betwixt the dark and the daylight”∗ of maternal subjectivity meditations on the threshold

Psychoanalysts have long looked to maternal experience to enhance our appreciation of what we may be feeling in our work. This tradition has drawn on psychoanalyst's construction of a particular kind of good‐enough mother who is typically muted in her subjectivity. Contemporary efforts are relying on more subjectively complex descriptions of mothering to make sense of the analyst's subjective experience. However, even recent portrayals of the maternal misapprehend the degree to which mothering strains the ability of all mothers to tolerate ambivalence and tend to simply replace previous idealizations with updated prototypes. The mother as currently constructed is valorized both for her resilience and for her ability to play easily with her feelings of hate and aggression toward her baby. The questions of how the mother feels about what she feels and what she does with how she feels are not addressed. Ironically, insights derived from an increased appreciation of the mutual affect and impact that character.
The clinical distinction between the affective psychoses and schizophrenia.

In an attempt to determine whether schizophrenic and affective illnesses are distinct entities or whether mixed states are really commoner than 'pure' forms of either, a discriminant function analysis was performed on clinical data from 146 schizophrenics and 146 patients with affective psychoses. The results were equivocal. The distribution of the weighted scores of the 292 patients on the disciminant function differed significantly from a normal distribution, but the distribution was trimodal rather than bimodal, and the boundary between schizophrenic and affective patients was at the peak of the distribution. Discrimination between the two groups was, however, better than that obtained in an analogous study of psychotic and neurotic depressions, and it is possible that the inclusion of data covering the outcome of the illness would increase discrimination to the point at which a bimodal distribution would be demonstrable.
An Adaptive QR Decomposition Processor for Carrier-Aggregated LTE-A in 28-nm FD-SOI

This paper presents an adaptive QR decomposition (QRD) processor for five-band carrier-aggregated Long Term Evolution-Advanced downlinks. The design uses time and frequency correlation properties of wireless channels to reduce QRD computations while maintaining an uncoded bit error rate loss below 1 dB. An analysis on the performance of a linear interpolating QRD is presented, and optimum distances for different channel conditions are suggested. The Householder transform suited for spatially correlated scenarios is chosen and modified for concurrent vector rotations resulting in high throughput. Based on these, a parallel hardware architecture suitable for easy reconfigurability and low power is developed and fabricated in 28-nm fully depleted silicon-on-insulator technology. The QRD unit occupies 205k gates of logic and has a maximum throughput of 22 MQRD/s while consuming 29 mW of power. On a circuit level, the back gate feature is leveraged to double operational frequency in low time-frequency correlation channels or to lower power consumption to 1.9 mW in favorable conditions. The proposed system provides designers with multiple levels of adaptive control from architectural to circuit level for power-performance tradeoffs and is well suited for mobile devices operating on limited battery energy.
Accuracy of CT for the detection of pleural adhesions: correlation with video-assisted thoracoscopic surgery.

STUDY OBJECTIVE The presence of pleural adhesions may render video-assisted thoracoscopic surgery (VATS) difficult or impossible. The aim of this study was to assess the value of chest CT in the detection of pleural adhesions prior to VATS. DESIGN Prospective study of the accuracy of chest CT in detecting pleural adhesions prior to VATS. SETTING Tertiary-referra; teaching hospital and Veterans Administration hospital. PATIENTS Between July 1994 and March 1995, 63 consecutive patients undergoing 64 VATS procedures were evaluated with chest CT prior to surgery. MEASUREMENTS AND RESULTS Preoperative scans were interpreted by consensus of two pulmonary radiologists prior to surgery. Suspected pleural adhesions and other findings related to the pleura were recorded on a form given to the surgeon prior to VATS. The surgeon confirmed or excluded each suspected adhesion during VATS, and documented any other lesions not identified preoperatively. Patient-by-patient and lesion-by-lesion analyses were performed. Pleural adhesions were correctly identified by CT in 28 of 39 cases (sensitivity, 71%) and excluded in 18 of 25 cases (specificity, 72%). On a lesion-by-lesion basis, 73 adhesions were identified during VATS, of which only 28 were identified prospectively at CT. There were 45 missed adhesions and 20 adhesions that were suggested falsely (sensitivity, 38%; specificity, 46%). Eighteen pleural spaces were correctly identified as being free of pleural adhesions. CONCLUSIONS CT is moderately sensitive and specific for preoperative identification of pleural adhesions in patients undergoing VATS but its accuracy is poorer for individual lesions.
Effects of transformational leadership on empowerment and team effectiveness

The purpose of this article is to investigate transformational leadership in relation to empowerment and team effectiveness. As part of an integrative model of leadership, transformational leadership style of superiors is proposed to be related to the strength of subordinate empowerment and team effectiveness. A total of 152 employees from various industries rated their superiors’ transformational leadership behaviors and also how much they felt empowered. They also evaluated their teams’ effectiveness in terms of innovativeness, communication and team performance. Findings suggest that transformational leadership contributes to the prediction of subordinates’ self‐reported empowerment and that the more a team’s members experience team empowerment, the more effective the team will be.
Using Regression Discontinuity to Test the Impact of a Tier 2 Reading Intervention in First Grade

Abstract Multitiered systems of reading instruction and intervention, including response to intervention, are widely used in early reading by schools to provide more intense services to students who need them. Research using randomized controlled trials has compared innovative Tier 2 interventions to business-as-usual Tier 2 approaches and established a number of important components that compose effective Tier 2 interventions in early reading. The purpose of this study was to test the impact of a Tier 2 intervention with Tier 2 compared to Tier 1 instruction alone using regression discontinuity. A cut score was used to assign first-grade students at risk for reading difficulties to Tier 2 intervention plus Tier 1 instruction. Students who missed the cut score in the control group received Tier 1 instruction only. Students in the treatment group, just below the cut score, made greater gains on the SAT10 total score and the individual subtests than students just above the cut score. Outcomes were not significant on oral reading fluency.
TraR directly regulates transcription initiation by mimicking the combined effects of the global regulators DksA and ppGpp

Significance TraR is a 73-amino acid protein encoded in the transfer region operon (tra) of the Escherichia coli conjugative F plasmid. Here we describe evidence for a model in which TraR mimics the combined regulatory activities of the transcription factor DksA and the second messenger ppGpp. By interacting with the residues in RNA polymerase that form a ppGpp binding pocket, we suggest that TraR provides a means for regulating transcription initiation by targeting the secondary channel even under conditions that do not result in induction of ppGpp. TraR-like proteins appear to be ubiquitous in bacteria even in phyla distant from the proteobacteriaceae, in support of the accumulating evidence that very small proteins can have a large impact on bacterial biology. The Escherichia coli F element-encoded protein TraR is a distant homolog of the chromosome-encoded transcription factor DksA. Here we address the mechanism by which TraR acts as a global regulator, inhibiting some promoters and activating others. We show that TraR regulates transcription directly in vitro by binding to the secondary channel of RNA polymerase (RNAP) using interactions similar, but not identical, to those of DksA. Even though it binds to RNAP with only slightly higher affinity than DksA and is only half the size of DksA, TraR by itself inhibits transcription as strongly as DksA and ppGpp combined and much more than DksA alone. Furthermore, unlike DksA, TraR activates transcription even in the absence of ppGpp. TraR lacks the residues that interact with ppGpp in DksA, and TraR binding to RNAP uses the residues in the β′ rim helices that contribute to the ppGpp binding site in the DksA–ppGpp–RNAP complex. Thus, unlike DksA, TraR does not bind ppGpp. We propose a model in which TraR mimics the effects of DksA and ppGpp together by binding directly to the region of the RNAP secondary channel that otherwise binds ppGpp, and its N-terminal region, like the coiled-coil tip of DksA, engages the active-site region of the enzyme and affects transcription allosterically. These data provide insights into the function not only of TraR but also of an evolutionarily widespread and diverse family of TraR-like proteins encoded by bacteria, as well as bacteriophages and other extrachromosomal elements.
In vivo phosphorylation of OmpR, the transcription activator of the ompF and ompC genes in Escherichia coli

An in vivo approach was taken to assess whether the phosphorylated state of the transcription activator OmpR was affected by changes in the osmolarity of the growth medium or by mutations in envZ, the gene encoding the inner membrane histidine kinase that phosphorylates OmpR. We present results that support the view that increased phosphorylation of OmpR is correlated with enhanced expression of ompC. The in vivo phosphorylation approach was also used to show that OmpR can be phosphorylated in an envZ null strain. This result indicates that phosphorylation cross talk can occur in vivo between OmpR and a kinase(s) that is functionally homologous to envZ.
Visual analytics: how much visualization and how much analytics?

The term Visual Analytics has been around for almost five years by now, but still there are on-going discussions about what it actually is and in particular what is new about it. The core of our view on Visual Analytics is the new enabling and accessible analytic reasoning interactions supported by the combination of automated and visual analysis. In this paper, we outline the scope of Visual Analytics using two problem and three methodological classes in order to workout the need for and purpose of Visual Analytics. By examples of analytic reasoning interaction, the respective advan- tages and disadvantages of automated and visual analysis methods are explained leading to a glimpse into the future of how Visual Analytics methods will enable us to go beyond what is possible when separately using the two methods.
From ‘Common Observation’ to Behavioural Risk Management

This article seeks to introduce a new site for surveillance studies. While a considerable body of literature has been devoted to the issue of workplace surveillance, little if any attention has been paid to the ‘caring cousin’ of workplace monitoring practices – employee assistance programmes. Employee assistance programmes (EAPs) work in concert with other forms of workplace monitoring, to identify threats to productivity. However, EAPs seek not only to identify, as do electronic and traditional modes of workplace monitoring, those workers who are, through their observable conduct, behaving in an unproductive or not optimally productive manner, they also seek to detect and address potential problems, or workers at particular risk of becoming unproductive, and to encourage the prophylactic treatment of such risks through ‘employee assistance’. In this attention to the detection of problems in potentia, EAPs are one of a family of peculiarly postindustrial surveillance technologies concerned with foresight, and with preventative systems of social administration.
Comparison of Generally Applicable Mechanisms for Preventing Embedded Event-Driven Real-Time Systems from Interrupt Overloads

This paper is related to event-driven embedded systems whose function can be divided into the real-time (RT) and non-RT parts. Such a system must be designed so that all predetermined timing constraints are met at runtime, even in adverse conditions such as an excessive rate of events caused by interrupts. In other words, the RT part is expected not to fail because of its criticality. In the paper, the interrupt overload problem (IOV) is introduced, then typical generally applicable solutions to the predictability part of the problem are presented along with our adaptive hardware/software mechanism for preventing the RT part from the same type of the problem, finally, the solutions are compared to summarize their attributes from the RT point of view.
L’accès au lexique mental dans une langue étrangère : le cas des francophones apprenant l’anglais

La recherche en acquisition du vocabulaire en L2 a tendance a investiguer les connaissances lexicales que les apprenants ont stockees en memoire ; certains specialistes considerent que l’acces a ces connaissances constitue un facteur determinant de la competence communicative. Des francophones apprenant l’anglais pourraient acceder de facon efficace a la forme ecrite des mots anglais, puisqu’une grande partie du vocabulaire anglais est derivee du francais. Les differences des systemes phonologiques des deux langues rendraient le traitement de ces memes mots plus problematique en mode oral. L’experience decrite ici – qui est basee sur la tâche de decision lexicale –compare l’acces a des mots anglais par un groupe d’apprenants francophones aux resultats pour un groupe d’anglophones. La performance des francophones a varie de facon significative, selon le mode de presentation des stimuli (formes ecrites ou orales).
TmPrime: fast, flexible oligonucleotide design software for gene synthesis

Herein we present TmPrime, a computer program to design oligonucleotide sets for gene assembly by both ligase chain reaction (LCR) and polymerase chain reaction (PCR). TmPrime offers much flexibility with no constraints on the gene and oligonucleotide lengths. The program divides the long input DNA sequence based on the input desired melting temperature, and dynamically optimizes the length of oligonucleotides to achieve homologous melting temperatures. The output reports the melting temperatures, oligonucleotide sequences and potential formation of secondary structures. Our program also provides functions on sequence pooling to separate long genes into smaller pieces for multi-pool assembly and codon optimization for expression. The software has been successfully used in the design and synthesis of green fluorescent protein fragment (GFPuv) (760 bp), human protein kinase B-2 (PKB2) (1446 bp) and the promoter of human calcium-binding protein A4 (S100A4) (752 bp) using real-time PCR assembly with LCGreen I, which offers a novel approach to compare the efficiency of gene synthesis. The purity of assembled products is successfully estimated with the use of melting curve analysis, which would potentially eliminate the necessity for agarose gel electrophoresis. This program is freely available at http://prime.ibn. a-star.edu. sg.
Mainstreaming Gender in Water Management: A Critical View

Abstract This article offers a critical perspective on gender mainstreaming in water management in India by exploring the linkages between pre-given notions of ‘gender’ in mainstreaming rhetoric and selected practices of water management. Evaluative studies have shown that gender mainstreaming is not effective if restricted to practices that try to make women visible or simply add a gender component in an intervention program. The much publicized ‘Women, Water and Work’ campaign initiated by India’s Self-Employed Women’s Association (SEWA) by and large excluded men, and the newly-instituted water sector reforms, which promote privatization and marginalize women in the process, are selected for analysis to distill the meanings of gender and social interests. Prospects for effective gender mainstreaming in water management will hinge on how the main agenda can address the transformation of gender relations and treat water as a human right so as to realize the Millennium Development Goals (MDGs) in developing countries.
Line segment based map building and localization using 2D laser rangefinder

We study a new scheme for map building and describe localization techniques for a mobile robot equipped with a 2D laser rangefinder. We propose to use line segments as the basic element for the purpose of localization and to build the map. Line segments do provide considerable geometric information about the scene that can also be used for accurate and fast localization. We introduce a new closed line segment (CLS) map which consists of only line segments and defines a closed and connected region. Virtual line segments are drawn, for the spots that do not adequately describe a line segment on the range data. These are further explored via navigation and we argue that the CLS map provides an efficient mobile robot exploration scheme. All these techniques have been implemented on our Nomad XR4000 mobile robot and results are described in this paper.
They all look alike, but so do we … sometimes: Perceptions of in-group and out-group homogeneity as a function of sex and context

The impact of gender on perceptions of group homogeneity was assessed using a memory paradigm. In the main experimental conditions, male and female subjects were presented with 12 pairs of photographs and gendered silhouettes. The photographs portrayed a series of environments (e.g. a kitchen) in public settings (e.g. a restaurant) and in domestic ones (e.g. at home). The connection of settings and gender of silhouettes varied across subjects. In control conditions, all silhouettes were of the same sex or were geometrical forms (triangles and squares). The subjects memorized the pairs of photographs and targets, and then had to reconstruct them. The experiment addressed three hypotheses. The categorization effect: within-category errors would exceed between-category errors, especially when gender was used as a categorization criterion. The out-group homogeneity effect: within-category errors concerning the out-group would be greater than those concerning the in-group. The social status effect: men would display more out-group homogeneity than women. Results provided evidence for the categorization and the out-group homogeneity hypotheses. They also supported to some extent the social status hypothesis. Different styles of processing of information were suggested by men's and women's performances. Men consistently displayed the out-group homogeneity bias, whereas women did not. Women took into account the kind of setting: they made more errors when matching the male or the female silhouettes to the domestic settings (the stereotypical in-group settings) than when matching these silhouettes to the public settings (the stereotypical out-group settings). Finally, sex-typing measures about the self were related to the subjects' behavioural performances, especially for women.
