New leader assimilation: process and outcomes

Purpose – This study seeks to test the researchers' theory that a leadership development intervention called “leader assimilation” for newly appointed leaders and their subordinates will facilitate feedback‐seeking and a leader‐team dialogue which will accelerate leader/team learning, leader adaptation, and relationship building between the new leaders and their teams.Design/methodology/approach – Robert Yin's positivistic multiple case study research method was used. Four primary modes of data collection were used in each of the three cases: observation during the five steps of the intervention, documentation review after the intervention, a pre‐ and post‐survey, and individual interviews with the leader and the leader's direct reports approximately seven days after the last phase of the intervention.Findings – The researchers found support for their theory from a leader and team perspective. The three leaders in the study experienced accelerated learning, adaptation, and they built relationships with th.
Convolutional Coding in Hybrid Type-II ARQ Schemeson Wireless

In our previous work, we have proposed a hybrid type-II Automatic Repeat reQuest (ARQ) scheme (Scheme 5) based on Rate Compatible Punctured Convolu-tional (RCPC) codes which performs signiicantly better than all the other ARQ schemes in all the channel conditions. In this work, we study the performance of Scheme 5 based on High Rate Optimized RCPC (HRO-RCPC) codes combined with simple repetition codes in more detail. The performance is investigated for diierent packet sizes and constraint lengths of the convolutional encoder in various fading environments. We have also studied the performance of the HRO-RCPC codes combined with optimized Rate Compatible Repetition Convolutional (RCRC) codes as another alternative for channel coding in hybrid type-II ARQ schemes. The corresponding simulation results show that these codes with high parent code rate perform almost as good as the HRO-RCPC codes with simple repetition codes at lower parent code rate.
Flash photography enhancement via intrinsic relighting

We enhance photographs shot in dark environments by combining a picture taken with the available light and one taken with the flash. We preserve the ambiance of the original lighting and insert the sharpness from the flash image. We use the bilateral filter to decompose the images into detail and large scale. We reconstruct the image using the large scale of the available lighting and the detail of the flash. We detect and correct flash shadows. This combines the advantages of available illumination and flash photography.
Can the conceptual framework be all things to all (wo)men

This paper explores the significant changes which have taken place in recent years, and continue to take place, in relation to the role of, and desirable characteristics of, a conceptual framework (CF). More precisely, we address the following three questions. 1) Why were conceptual frameworks created, or not created? 2) What is the role of conceptual frameworks today? and 3) What is the answer to our title question? While exploring the origins of the search of CF at the beginning of the twentieth century and adopting a multi-national (as well as international) approach, we discuss the origins, role and possible rationales for the economics-based CFs of the IASB and other bodies with a strong Anglo-Saxon influence. This analysis leads us to partially reject the commonly held view that public-sector regulators have, and need, no conceptual framework. More precisely, our analysis on CF-based standard-setting points out the inherent contradictions in trying to produce a single properly coherent set of notions and practices which is applied in significantly different contexts and for significantly different purposes.
Difficulties faced by color-anomalous observers in interpreting color displays

We have reconstructed the color spaces of normal observers and of protanomalous and deuteranomalous observers by measuring the time that each requires to decide whether pairs of colors are the same or different. By means of a multidimensional scaling procedure these response times were ordered into a space such that colors that were more quickly discriminated were farther from one another. When presented with a set of colors that yields an approximately rectangular color space for normal observers, anomalous observers have difficulty in discriminating colors that lie on lines parallel to the red-green cardinal axis. Their color spaces suggest that the gamut of color that anomalous observers experience is far more impoverished than is usually thought to be the case, and that their ability to interpret color-coded displays is correspondingly limited.
The control of growth and differentiation in normal and leukemic blood cells

The establishment of a cell culture system for the clonal development of hematopoietic cells has made it possible to discover the proteins that control growth and differentiation of different hematopoietic cell lineages and the molecular basis of normal and abnormal cell development in blood‐forming tissues. A model system with myeloid cells has shown that normal hematopoietic cells require different proteins to induce cell multiplication and cell differentiation, and that a cascade of interactions between proteins determines the correct balance between immature and mature cells in normal development. Gene cloning has shown that there is a family of different genes for these proteins. Normal protein regulators of hematopoiesis can control the abnormal growth of certain types of leukemic cells and suppress malignancy by inducing differentiation to mature nondividing cells. Genetic abnormalities that give rise to malignancy in these leukemic cells can be bypassed and their effects nullified by inducing differentiation, which stops cells from multiplying. These hematopoietic regulatory proteins are active in culture and in vivo and have been used clinically to correct defects in blood cell development. The results provide new approaches to therapy.
Probing the Topological Properties of Complex Networks Modeling Short Written Texts

In recent years, graph theory has been widely employed to probe several language properties. More specifically, the so-called word adjacency model has been proven useful for tackling several practical problems, especially those relying on textual stylistic analysis. The most common approach to treat texts as networks has simply considered either large pieces of texts or entire books. This approach has certainly worked well—many informative discoveries have been made this way—but it raises an uncomfortable question: could there be important topological patterns in small pieces of texts? To address this problem, the topological properties of subtexts sampled from entire books was probed. Statistical analyses performed on a dataset comprising 50 novels revealed that most of the traditional topological measurements are stable for short subtexts. When the performance of the authorship recognition task was analyzed, it was found that a proper sampling yields a discriminability similar to the one found with full texts. Surprisingly, the support vector machine classification based on the characterization of short texts outperformed the one performed with entire books. These findings suggest that a local topological analysis of large documents might improve its global characterization. Most importantly, it was verified, as a proof of principle, that short texts can be analyzed with the methods and concepts of complex networks. As a consequence, the techniques described here can be extended in a straightforward fashion to analyze texts as time-varying complex networks.
The relationship between intellectual capital and financial performance: An empirical investigation in an Iranian company

In the Intellectual Capital (IC) literature, only a few studies have analyzed the relationships among the components of IC and organizational success. This study provides further insight into the role of IC in organizational performance, especially financial performance. In this order, Value Added Intellectual Coefficient (VAICTM) method has been used for measuring the value based performance of the company. Corporate performance measures used in this analysis are profitability, Employee productivity, and Growth in sales. The intellectual capital (human capital and structural capital) and physical capital of the company have been analyzed and their impact on corporate performance has been measured using multiple regression technique. Findings from the empirical analysis indicate that the relationships between the performance of a company’s intellectual capital and profitability, Employee productivity, and Growth in sales are informative. The empirical findings suggest that the performance of a company’s intellectual capital can explain profitability and productivity.
Fibroblast-collagen interactions in the formation of the secondary stroma of the chick cornea

Fibroblasts invade the primary corneal stroma of the 6-day-old chick embryo eye. The way in which these cells build the secondary stroma has been studied by microscope examination of the stroma during the subsequent 8 Days. Eyes were embedded in low viscosity nitrocellulose, and 30-micrometer tangential sections of cornea were cut and stained with azan (giving blue collagen and red cells). These sections were sufficiently thick to include enough cells and collagen for stromal organization to be visible under Nomarski optics. Three days after invasion, the fibroblasts extend along collagen bundles in the posterior region of the stroma; surprisingly, fibroblasts near the epithelium are more rounded. The collagen itself is organized in orthogonal bundles rather than in sheets. Measurements show that posterior bundles increase in size with time while anterior stroma si similar in diameter to primary stroma. These observations confirm that the epithelium continues to deposit primary stroma up to at least the 14th day. They show, moreover, that fibroblasts deposit collagen fibrils on extant stroma and that the farther a bundle is from the epithelium, and hence the longer the period since it was first laid down, the wider it is likely to be. Analysis of the results and existing data on hyaluronic acid levels in the stroma suggests that Bowman's membrane, the region of anterior stroma that remains uncolonized by cells, is, during this period at least, primary stroma laid down but as yet unswollen.
Tailoring Retrieval to Support Case-Based Teaching

This paper describes how a computer program can support learning by retrieving and presenting relevant stories drawn from a video case base. Although this is an information retrieval problem, it is not a problem that fits comfortably within the classical IR model (Salton & McGill, 1983) because in the classical model the computer system is too passive. The standard model of IR assumes that the user will take the initiative to formulate retrieval requests, but a teaching system must be able to initiate retrieval and formulate retrieval requests automatically. We describe a system, called SPIEL, that performs this type of retrieval, and discuss theoretical challenges addressed in implementing such a system. These challenges include the development of a representation language for indexing the system's video library, and the development of set of retrieval strategies and recognition knowledge that allow the system to locate educationally relevant stories.
Identification of inflammatory gene modules based on variations of human endothelial cell responses to oxidized lipids

Oxidized phospholipids are thought to promote atherogenesis by stimulating endothelial cells (ECs) to produce inflammatory cytokines, such as IL-8. In studies with mouse models, we previously demonstrated that genetic variation in inflammatory responses of endothelial cells to oxidized lipids contributes importantly to atherosclerosis susceptibility. We now show that similar variations occur in cultured aortic ECs derived from multiple heart transplant donors. These variations were stably maintained between passages and, thus, reflect either genetic or epigenetic regulatory differences. Expression array analysis of aortic EC cultures derived from 12 individuals revealed that >1,000 genes were regulated by oxidized phospholipids. We have used the observed variations in the sampled population to construct a gene coexpression network comprised of 15 modules of highly connected genes. We show that several identified modules are significantly enriched in genes for known pathways and confirm a module enriched for unfolded protein response (UPR) genes using siRNA and the UPR inducer tunicamycin. On the basis of the constructed network, we predicted that a gene of unknown function (MGC4504) present in the UPR module is a target for UPR transcriptional activator ATF4. Our data also indicate that IL-8 is present in the UPR module and is regulated, in part, by the UPR. We validate these by using siRNA. In conclusion, we show that interindividual variability can be used to group genes into pathways and predict gene–gene regulatory relationships, thus identifying targets potentially involved in susceptibility to common diseases such as atherosclerosis.
An Investigation of Body Appreciation, Ethnic Identity, and Eating Disorder Symptoms in Black Women

Positive body image, such as body appreciation or acceptance, has gone largely unexamined in women of color in comparison with more pathological body attitudes. In an effort to promote and extend positive body image research, this study examined the reliability and validity of the Body Appreciation Scale (BAS) in Black college women, as well as the relation between ethnic identity and body appreciation. Participants were 228 Black college women (M age = 19.89, SD = 4.57). The relation between BAS scores and measures of appearance evaluation, self-esteem, Western beauty ideal internalization, eating disordered behavior, and teasing was examined to investigate convergent and divergent validity. Results supported the construct validity of this measure. Similar to previous research, a confirmatory factor analysis supported a unidimensional factor structure. Ethnic identity was moderately, positively associated with body appreciation. Western beauty ideal internalization mediated the relation between ethnic identity and eating, weight, and shape concerns. Overall, findings support the use of the BAS with Black college women.
MHC Class II Expression Identifies Functionally Distinct Human Regulatory T Cells1

It has been known for decades that circulating human CD4 cells can express functional MHC class II molecules that induce T cell nonresponsiveness with Ag presentation. Because there is significant expression of MHC class II (MHC-II) determinants (DR) on a subpopulation CD4+CD25high regulatory T cells (Treg), we examined the function of CD4 cells expressing MHC-DR. We demonstrate that MHC-II expression on human CD4+CD25high T cells identifies a functionally distinct population of Treg that induces early contact-dependent suppression that is associated with high Foxp3 expression. In striking contrast, MHC-II− CD4+CD25high Treg induce early IL-4 and IL-10 secretion and a late Foxp3-associated contact-dependent suppression. The DR expressing CD25high Treg express higher levels of Foxp3 message and protein, compared with the DR−CD25high Treg population. Direct single-cell cloning of CD4+CD25high Treg revealed that, regardless of initial DR expression, ex vivo expression of CD25high, and not DR, predicted which clones would exhibit contact-dependent suppression, high levels of Foxp3 message, and an increased propensity to become constitutive for DR expression. Thus, the direct ex vivo expression of MHC-II in the context of CD25high identifies a mature, functionally distinct regulatory T cell population involved in contact-dependent in vitro suppression.
The Effects of a Sport-Specific Maximal Strength and Conditioning Training on Critical Velocity, Anaerobic Running Distance, and 5-km Race Performance.

PURPOSE To investigate the effects of a sport-specific maximal 6-wk strength and conditioning program on critical velocity (CV), anaerobic running distance (ARD), and 5-km time-trial performance (TT). METHODS 16 moderately trained recreational endurance runners were tested for CV, ARD, and TT performances on 3 separate occasions (baseline, midstudy, and poststudy). DESIGN Participants were randomly allocated into a strength and conditioning group (S&C; n = 8) and a comparison endurance-training-only group (EO; n = 8). During the first phase of the study (6 wk), the S&C group performed concurrent maximal strength and endurance training, while the EO group performed endurance-only training. After the retest of all variables (midstudy), both groups subsequently, during phase 2, performed another 6 wk of endurance-only training that was followed by poststudy tests. RESULTS No significant change for CV was identified in either group. The S&C group demonstrated a significant decrease for ARD values after phases 1 and 2 of the study. TT performances were significantly different in the S&C group after the intervention, with a performance improvement of 3.62%. This performance increase returned close to baseline after the 6-wk endurance-only training. CONCLUSION Combining a 6-wk resistance-training program with endurance training significantly improves 5-km TT performance. Removing strength training results in some loss of those performance improvements.
Tool Support for Class Library ReuseS

OO-CaRE is a classiication and retrieval tool to support reuse of class libraries. The tool is based on the faceted classiication method where a component is classiied using a collection of terms belonging to diierent facets. The tool provides a retrieval mechanism which returns the set of matching classes and their \closeness" to the the given query. The priority of a facet (signifying its importance) can be dynamically set by the reuser thus providing additional exibility in the formulation of queries. The tool is built in the Eiiel environment using Eiiel class libraries.
Concomitant infusion of low doses of rFVIIa and FEIBA in haemophilia patients with inhibitors

Summary. Patients with severe haemophilia A and an inhibitor may become refractory to FEIBA and/or recombinant factor VIIa (rFVIIa). Sequential therapy with both products has been reported in such patients. In this pilot study, we examined the safety and efficacy of combined rFVIIa and FEIBA therapy in patients with haemophilia A and inhibitors during bleeding episodes. We also tried to evaluate whether thrombin generation (TG), by various mixtures of these agents, can serve as a guide for tailoring therapy. TG was measured in plasma taken from eight haemophilia A patients. Increasing concentrations of rFVIIa, FEIBA or both were added ex vivo to the plasmas, and TG was induced by recalcification. Since low concentrations of rFVIIa and FEIBA had either an additive or a synergistic effect in all patients, the lowest combination, yielding TG comparable or lower than TG achieved with either FEIBA 100 U kg−1 or rFVIIa 160 μg kg−1 alone, was selected for the treatment of bleeding episodes. Five patients with a high titre of an inhibitor (8–1300 BU), including one previously refractory to infusions of rFVIIa at doses up to 400 μg kg−1 X4 daily, were treated with combinations of 30–70 μg kg−1 rFVIIa and 20–30 U kg−1 FEIBA during a total number of 400 bleeding episodes with excellent haemostatic effect. No adverse events and no DIC were observed following these infusions. Concomitant infusion of low‐dose rFVIIa and low‐dose FEIBA, seems to be safe, efficacious and economical in patients refractory to rFVIIa and probably other haemophilia A patients with an inhibitor.
The content and validity of music-genre stereotypes among college students

The present research examined the content and validity of stereotypes about fans of 14 different music genres (e.g. country, rap, rock). In particular, we focused on stereotypes concerning fans’ personalities (e.g. extraversion, emotional stability), personal qualities (e.g. political beliefs, athleticism), values (e.g. for peace, for wisdom), and alcohol and drug preferences (e.g. wine, hallucinogens). Previous research has shown that music is linked to a variety of psychological characteristics, that music is used to convey information about oneself to observers, and that observers can infer personality on the basis of music preferences. Guided by such research, we predicted and found that individuals have robust and clearly defined stereotypes about the fans of various music genres (Study 1), and that many of these music-genre stereotypes possess a kernel of truth (Study 2). Discussion focuses on the potential role of music-genre stereotypes in self-expression and impression formation.
Prerequisite Study for the Development of Embedded Instrumentation for Plant Phenotyping Using Computational Vision

This paper sought to investigate the most relevant criteria for determination of an embedded stereo vision system, both in the choice of the cameras and in terms of the processing platform to be used for plant phenotyping. Since this paper is a result of a preliminary study of the real implementation itself, the main motivation was to evaluate the accuracy of the low-cost visual system's field of view and its viability for the proposed application. In addition, the real agricultural scenario was presented and studied, showing how the stereo system should be modeled to meet the accuracy and the portability requirements for using in situ machine vision in agricultural decision-making processes.
Face Detection In Profile Views Using Fast Discrete Curvelet Transform (Fdct) And Support Vector Machine (Svm)

Abstract Human face detection is an indispensable component in face processing applications, including automatic face recognition, security surveillance, facial expression recognition, and the like. This paper presents a profile face detection algorithm based on curvelet features, as curvelet transform offers good directional representation and can capture edge information in human face from different angles. First, a simple skin color segmentation scheme based on HSV (Hue - Saturation - Value) and YCgCr (luminance - green chrominance - red chrominance) color models is used to extract skin blocks. The segmentation scheme utilizes only the S and CgCr components, and is therefore luminance independent. Features extracted from three frequency bands from curvelet decomposition are used to detect face in each block. A support vector machine (SVM) classifier is trained for the classification task. In the performance test, the results showed that the proposed algorithm can detect profile faces in color images with good detection rate and low misdetection rate
