Measuring climate for work group innovation: development and validation of the team climate inventory

Summary This paper reports the development and psychometric validation of a multi-dimensional measure of facet-specific climate for innovation within groups at work: the Team Climate Inventory (TCI). Brief reviews of the organizational climate and work group innovation literatures are presented initially, and the need for measures of facet-specific climate at the level of the proximal work group asserted. The four-factor theory of facet-specific climate for innovation, which was derived from these reviews, is described, and the procedures used to operationalize this model into the original version measure described. Data attesting to underlying factor structure, internal homogeneity, predictive validity and factor replicability across groups of the summarized measure are presented. An initial sample of 155 individuals from 27 hospital management teams provided data for the exploratory factor analysis of this measure. Responses from 121 further groups in four occupations (35 primary health care teams, 42 social services teams, 20 psychiatric teams and 24 oil company teams; total Na 971) were used to apply confirmatory factor analysis techniques. This five-factor, 38-item summarized version demonstrates robust psychometric properties, with acceptable levels of reliability and validity. Potential applications of this measure are described and the implication of these findings for the measurement of proximal work group climate are discussed. #1998 John Wiley & Sons, Ltd.
The influence of lexical status and neighborhood density on children's nonword repetition

ABSTRACT This study examined effects of lexical status and neighborhood density of constituent syllables on children's nonword repetition and interactions with nonword length. Lexical status of the target syllable impacted repetition accuracy for the longest nonwords. In addition, children made more errors that changed a nonword syllable to a word syllable than the reverse. Syllables from dense versus sparse neighborhoods were repeated more accurately in three- and four-syllable nonwords, but there was no effect of density for two-syllable nonwords. The effect of neighborhood density was greater for a low versus high vocabulary group. Finally, children's error responses were from more dense neighborhoods than the target syllables. The results are congruent with models of nonword repetition that emphasize the influence of long-term lexical knowledge on children's performance.
Politics of Language in the Ex-Soviet Muslim States: Azerbaijan, Uzbekistan, Kazakhstan, Kyrgyzstan, Turkmenistan and Tajikistan

"Politics of Language in the Ex-Soviet Muslim States" offers a unique and timely analysis of language policies in the central Asian states of the former Soviet Union. The authors relate these policies to broad issues such as nation-building, language planning, and multilingualism. The book is a comprehensive survey of language policy in the five newly independent states with largely Turkic-speaking populations and in the Tajic republic, with its mainly Iranian-speaking population. It addresses each state's consideration over how the use of Russian--widespread as a second language among the Turkic-speaking peoples and known as a first language for Soviet-era immigrants regardless of ethnicity--should relate to use of the local varieties of Turkic or Iranian. It also addresses efforts in each state to elaborate the local variety of Turkic or Iranian for use as public discourse in administration, law, business, and politics, including teaching the language to its nominal speakers, and considers the relation between these languages and those of local ethnic minorities. The authors utilize previously unpublished empirical data, which is presented in both a clear narrative and conceptual framework.Jacob M.

Modeling MW-dependent ramp rate in the electricity market

Maintaining certain amount of reserves in the realtime electricity market is an important task to ensure the reliability of the grid operation. The traditional reserve designation method calculates the reserve capability of a resource based on its average ramp rate, which may misrepresent the true reserve capacity of the system. System reliability and economics could be affected by such misrepresentation under certain conditions. This paper proposes an efficient MW-dependent ramp rate reserve model that utilizes the ramp rate of a generator at its energy desired dispatch point (DDP) in calculating reserve, which accurately reflects the true reserve capacity of the system in real time. The proposed model is prototyped in ISO New England's real time market and the solution is demonstrated to be more accurate and efficient, thus improving the market operation's efficiency and reliability.
Cooperative Transcriptional Activation by the Neurogenic Basic Helix-Loop-Helix Protein MASH1 and Members of the Myocyte Enhancer Factor-2 (MEF2) Family*

Establishment of skeletal muscle and neural cell types is controlled by families of myogenic and neurogenic basic helix-loop-helix (bHLH) proteins, respectively. Myogenic bHLH proteins have been shown to activate skeletal muscle transcription in collaboration with members of the myocyte enhancer factor-2 (MEF2) family of MCM1-agamous-deficiens-serum response factor (MADS)-box transcription factors, which are expressed in differentiated myocytes and neurons. Here, we show that the neurogenic bHLH protein MASH1 interacts with members of the MEF2 family and that this interaction, mediated by the DNA binding and dimerization domains of these factors, results in synergistic activation of transcription through either the MASH1 or the MEF2 DNA binding site. Consistent with their involvement in activation of neuronal gene expression, members of the MEF2 family are expressed in P19 embryonal carcinoma cells that have been induced to form neurons following treatment with retinoic acid. These results suggest that members of the MEF2 family perform similar roles in synergistic activation of transcription in myogenic and neurogenic lineages by serving as cofactors for cell type-specific bHLH proteins.
Gender and Usage Patterns of English in South African Urban and Rural Contexts.

Relatively little attention has been paid to gender issues in the investigation of world Englishes, in spite of their common focus, over the past twenty years, on the analysis of (hidden) ways in which power is exercised in society. Recent studies in gender and language have begun to reveal ways in which gender contributes to linguistic pluralism and diversity in post-colonial societies. This paper draws on studies of gender and bilingualism by Gal (1978, 1979) and Burton et al. (1994), to investigate ways in which acquisition and usage patterns of English as an additional language in KwaZulu-Natal, South Africa, may be gendered. It extends work done for a Masters thesis (Appalraju, 1999), which first recognised and explored the gendered nature of English acquisition and usage patterns of school pupils from a rural environment. These data are contrasted with English usage patterns of Zulu-speaking pupils at an urban school. The two sets of results are interpreted in terms of the construction of gender identities, to explore ways in which gender identities may be changing in modernising contexts, and to reveal gender as one hitherto neglected factor which is impacting on the current spread of English as an additional language.
Understanding Boys' Bodies and Masculinity in Early Childhood

Children as young as five experience feelings of body image dissatisfaction. However, body image research has tended to focus on females due to myriad social and cultural issues girls/women confront in terms of their body image. Therefore, in an attempt to redress this imbalance, this paper investigates the constructions of body image and health among young boys between 5-6 years of age using qualitative research. While the paper highlights the young boys’ voices, it specifically identifies how boys construct notions around their bodies and body identity. This research highlights the early age at which boys begin to reflect upon, compare, and contrast their own bodies with others and the images surrounding them.
Elements of Successful Mentoring of a Female School Leader

This case study examines the successful mentoring relationship between an early-career principal and her mentor as they participated in an Entry Year Program for early-career school administrators as a component of an Administrative Leadership Academy (ALA). Using a feminist poststructuralist framework, the findings show that contrary to traditional mentoring paradigms, which hold that the exchange of information is passed from the mentor to the protégé, the success of this mentoring experience was the nonhierarchal and mutual learning interactions afforded the protégé and her mentor. Implications of such findings are offered for future entry programs to increase support of more nontraditional leaders moving into the school principalship.
MULTIPARTY TALK IN FAMILY THERAPY: COMPLEXITY BREEDS OPPORTUNITY

Discursive investigations of multiparty talk can aid family therapists. In this article, discourse analysis was used to demonstrate how a therapist and family members concurrently engage multiple conversational partners to accomplish forward movement after conversational impasses. By looking closer at conversational practices, therapists can become more aware and creative as they attempt to move forward with clients. With the microlens cultivated in a discursive analysis, therapists can adopt alternative “conversational courses of action” as they become more sensitive to constructing “interventions” with clients. With this sensitivity, it is less likely that therapists will label clients resistant as they learn to become more resourceful and conversationally adaptive participants in stalled conversations. They may then better position themselves to recognize the enormous, often previously unnoticed, opportunities to join family members in multiparty talk.
Positivism and the Promise of the Social Sciences

This paper contends that Auguste Comte, John Stuart Mill and Karl Marx, though politically disparate, were all vigorous proponents of a scientific approach to human phenomena, and in that way were harbingers of modem social and behavioral science. We show how for these three thinkers social science was inextricably linked to a notion of human betterment embodied in a specific moral and political vision, and argue that a dilemma emerged from their belief that such a science would lead to objective prescriptions. We then analyze how each resolved this dilemma, and review major disciplinary developments to illustrate how the modem professionalized version of social science is a response to this same dilemma. Knowledge of the historical conditions and intentions that surrounded the extension of scientific principles from physical to human arenas may better enable modem practitioners to understand why the promise the early positivists saw in social science has gone unfulfilled.
Human immunodeficiency virus type 1 envelope glycoprotein molecules containing membrane fusion-impairing mutations in the V3 region efficiently undergo soluble CD4-stimulated gp120 release

The ability of soluble forms of CD4 to induce gp120 release from the human immunodeficiency virus type 1 envelope glycoprotein complex may reflect molecular events associated with membrane fusion. The third hypervariable (V3) region of gp120 appears to play a role in fusion independent of CD4 binding. We demonstrate herein that envelope glycoprotein molecules rendered fusion defective by mutations in conserved residues within the V3 region nevertheless undergo efficient soluble CD4-induced gp120 release.
Isolation of a Novel Phage with Activity against Streptococcus mutans Biofilms

Streptococcus mutans is one of the principal agents of caries formation mainly, because of its ability to form biofilms at the tooth surface. Bacteriophages (phages) are promising antimicrobial agents that could be used to prevent or treat caries formation by S. mutans. The aim of this study was to isolate new S. mutans phages and to characterize their antimicrobial properties. A new phage, ɸAPCM01, was isolated from a human saliva sample. Its genome was closely related to the only two other available S. mutans phage genomes, M102 and M102AD. ɸAPCM01 inhibited the growth of S. mutans strain DPC6143 within hours in broth and in artificial saliva at multiplicity of infections as low as 2.5x10-5. In the presence of phage ɸAPCM01 the metabolic activity of a S. mutans biofilm was reduced after 24 h of contact and did not increased again after 48 h, and the live cells in the biofilm decreased by at least 5 log cfu/ml. Despite its narrow host range, this newly isolated S. mutans phage exhibits promising antimicrobial properties.
Replacing an Inpatient Electronic Medical Record

Summary Objective: Since it is important to develop strategies for the successful implementation of electronic clinical information systems, the aim of this study is to explore where, and to what extent, users’ attitudes toward the former system that is being replaced may vary. Methods: A cross-sectional survey of 346 nurses and physicians practicing in two Canadian teaching hospitals resulted in a total response rate of 63%. User attitudes were measured in three dimensions: a) user satisfaction with the system’s quality attributes, b) perceived system usefulness, and c) perceived impact on quality of care and patient safety. The current system (the one being replaced) was analyzed as a dual system composed of both paper-based and electronic records. Results: The results on user satisfaction demonstrate a wide variation in opinions, with satisfaction ranging from 4.2 to 7.7 on a 10-point disagree-agree, Likert scale. The quality attributes varied by record type, with differences that were systematically in favor of the electronic record component, which received higher scores. The results also highlighted large differences by user group. Physicians and nurses systematically rated the two record formats differently. The nurses were more satisfied with the attributes of the paper-based record. Multivariate regression analyses results also revealed strong interdependencies among the three dimensions of user attitudes, to the extent that perceived system usefulness was strongly correlated with system quality attributes and the system outcomes were also correlated, although less strongly, with the two former system dimensions. Conclusion: Understanding users’ attitudes toward a clinical information system in use, both in its paper and electronic aspects, is crucial for developing more successful implementation strategies for electronic record systems.
The Person and the Situation: Perspectives of Social Psychology

How does the situation we're in influence the way we behave and think? Professors Ross and Nisbett eloquently argue that the context we find ourselves in substantially affects our behavior in this timely reissue of one of social psychology's classic textbooks.

The evolutionary reality of higher taxa in mammals

Species are generally regarded as a fundamental unit of biodiversity. By contrast, higher taxa such as genera and families, while widely used as biodiversity metrics and for classification and communication, are generally not believed to be shaped by shared evolutionary processes in the same way as species. We use simulations to show that processes which are important for emergence of evolutionarily significant units (ESUs) at the species level, namely geographical isolation and ecological divergence, can generate evolutionary independence above the species level and thereby lead to emergence of discrete phylogenetic clusters (higher ESUs). Extending phylogenetic approaches for delimiting evolutionarily significant species to broader phylogenetic scales, we find evidence for the existence of higher ESUs in mammals. In carnivores, euungulates and lagomorphs the hierarchical level of units detected correspond, on average, to the level of family or genus in traditional taxonomy. The units in euungulates are associated with divergent patterns of body mass, consistent with occupation of distinct ecological zones. Our findings demonstrate a new framework for studying biodiversity that unifies approaches at species and higher levels, thus potentially restoring higher taxa to their historical status as natural entities.
Sampled Image Tagging and Retrieval Methods on User Generated Content

Traditional image tagging and retrieval algorithms have limited value as a result of being trained with heavily curated datasets. These limitations are most evident when arbitrary search words are used that do not intersect with training set labels. Weak labels from user generated content (UGC) found in the wild (e.g., Google Photos, FlickR, etc.) have an almost unlimited number of unique words in the metadata tags. Prior work on word embeddings successfully leveraged unstructured text with large vocabularies, and our proposed method seeks to apply similar cost functions to open source imagery. Specifically, we train a deep learning image tagging and retrieval system on large scale, user generated content (UGC) using sampling methods and joint optimization of word embeddings. By using the Yahoo! FlickR Creative Commons (YFCC100M) dataset, such an approach builds robustness to common unstructured data issues that include but are not limited to irrelevant tags, misspellings, multiple languages, polysemy, and tag imbalance. As a result, the final proposed algorithm will not only yield comparable results to state of the art in conventional image tagging, but will enable new capability to train algorithms on large, scale unstructured text in the YFCC100M dataset and outperform cited work in zero-shot capability.
Frequency and Prognostic Relevance of FLT3 Mutations in Saudi Acute Myeloid Leukemia Patients

The Fms-like tyrosine kinase-3 (FLT3) is a receptor tyrosine kinase that plays a key role in cell survival, proliferation, and differentiation of hematopoietic stem cells. Mutations of FLT3 were first described in 1997 and account for the most frequent molecular mutations in acute myeloid leukemia (AML). AML patients with FLT3 internal tandem duplication (ITD) mutations have poor cure rates the prognostic significance of point mutations; tyrosine kinase domain (TKD) is still unclear. We analyzed the frequency of FLT3 mutations (ITD and D835) in patients with AML at diagnosis; no sufficient data currently exist regarding FLT3 mutations in Saudi AML patients. This study was aimed at evaluating the frequency of FLT3 mutations in patients with AML and its significance for prognosis. The frequency of FLT3 mutations in our study (18.56%) was lower than many of the reported studies, FLT3-ITD mutations were observed in 14.4%, and FLT3-TKD in 4.1%, of 97 newly diagnosed AML patients (82 adult and 15 pediatric). Our data show significant increase of FLT3 mutations in male more than female (13 male, 5 female). Our results support the view that FLT3-ITD mutation has strong prognostic factor in AML patients and is associated with high rate of relapse, and high leucocytes and blast count at diagnosis and relapse.
Blind identification of FIR MIMO channels by decorrelating subchannels

We study blind identification and equalization of finite impulse response (FIR) and multi-input and multi-output (MIMO) channels driven by colored signals. We first show a sufficient condition for an FIR MIMO channel to be identifiable up to a scaling and permutation using the second-order statistics of the channel output. This condition is that the channel matrix is irreducible (but not necessarily column-reduced), and the input signals are mutually uncorrelated and of distinct power spectra. We also show that this condition is necessary in the sense that no single part of the condition can be further weakened without another part being strengthened. While the above condition is a strong result that sets a fundamental limit of blind identification, there does not yet exist a working algorithm under that condition. In the second part of this paper, we show that a method called blind identification via decorrelating subchannels (BIDS) can uniquely identify an FIR MIMO channel if a) the channel matrix is nonsingular (almost everywhere) and column-wise coprime and b) the input signals are mutually uncorrelated and of sufficiently diverse power spectra. The BIDS method requires a weaker condition on the channel matrix than that required by most existing methods for the same problem.
Protein kinase inhibitors can control the progression of endometriosis in vitro and in vivo

Endometriosis affects 6–10% of women in their reproductive years, causing chronic pelvic pain and infertility. Its pathogenesis remains poorly understood and current treatments, based on hormonal therapy or surgery, are often insufficient. The purpose of our study was to investigate the role of the ERK pathway in the development of endometriosis and to test the effects of protein kinase inhibitors on the proliferation of endometriotic cells in vitro and in vivo. We studied ex vivo human endometrial and endometriotic cells in culture. Stromal and epithelial cells were extracted from endometrial and endometriotic biopsies from patients with endometriosis and from patients without endometriosis. The ERK pathway was explored by western blot on cell lysates and by ELISA on total crushed specimens of endometrium. Cells in culture were treated with A771726, PD98059, and U0126. Human endometriotic lesions were implanted in nude mice. Mice were treated with A771726, leflunomide, PD98059, U0126 or PBS during 2 weeks before sacrifice and extraction of the endometriotic implants for histological examination. We found that the ERK pathway was significantly activated in endometriotic cells and in endometrial cells from patients with endometriosis compared to endometrial cells of control patients, both by ELISA and by western blot. This phenomenon was associated with an increased proliferation of endometriotic cells compared to endometrial cells. Treating endometriotic cells with A771726, PD98059 or U0126 abrogated the phosphorylation of ERK and significantly decreased the cellular proliferation in vitro. In vivo, A771726, leflunomide, PD98059, and U0126 controlled the growth of endometriotic implants in the mouse model of endometriosis. Our study shows that protein kinase inhibitors could be new candidates to treat endometriosis. However, further studies are needed to evaluate their effects and tolerability in humans.
