DETERMINANTS OF SUCCESSFUL KNOWLEDGE MANAGEMENT PROGRAMS

The main objective of this paper is to investigate and identify the main determinants of successful knowledge management (KM) programs. We draw upon the institutional theory and the theory of technology assimilation to develop an integrative model of KM success that clarifies the role of information technology (IT) in relation to other important KM infrastructural capabilities and to KM process capabilities. We argue that the role of IT cannot be studied in isolation and that the effect of IT on KM success is fully mediated by KM process capabilities. The research model is tested with a survey study involving 191 KM practitioners. The empirical results provided strong support for the model. In addition to its theoretical contributions, this study also presents important practical implications through the identification of specific infrastructural capabilities leading to KM success.
Algorithms for Graph Similarity and Subgraph Matching

We deal with two independent but related problems, those of graph similarity and subgraph matching, which are both important practical problems useful in several ﬁelds of science, engineering and data analysis. For the problem of graph similarity, we develop and test a new framework for solving the problem using belief propagation and related ideas. For the subgraph matching problem, we develop a new algorithm based on existing techniques in the bioinformatics and data mining literature, which uncover periodic or infrequent matchings. We make substantial progress compared to the existing methods for both problems
Highly sensitive RF energy harvester using gate and bulk self compensation techniques

This paper presents a highly sensitive RF energy harvester. The developed prototype is based on an improved rectifier, that makes use of passive self compensation and biasing techniques to increase the sensitivity and efficiency of the device. These techniques include gate compensation and bulk DC biasing to lower the rectifier transistors threshold voltage. The rectifier exhibits a very high sensitivity of 84 mV at 1 V / 1 μW output voltage and power.

Learning About Beta: Time-Varying Factor Loadings, Expected Returns, and the Conditional CAPM

This paper explores the theoretical and empirical implications of time-varying and unobservable beta. Investors infer factor loadings from the history of returns via the Kalman filter. Due to learning, the history of beta matters. Even though the conditional CAPM holds, standard OLS tests can reject the model if the evolution of investor's expectations is not properly modelled. We use our methodology to explain returns on the twenty-five size and book-to-market sorted portfolios. Our learning version of the conditional CAPM produces pricing errors that are significantly smaller than standard conditional or unconditional CAPM and the model is not rejected by the data.
One-Class SVMs for Document Classification

We implemented versions of the SVM appropriate for one-class classification in the context of information retrieval. The experiments were conducted on the standard Reuters data set. For the SVM implementation we used both a version of Schoelkopf et al. and a somewhat different version of one-class SVM based on identifying "outlier" data as representative of the second-class. We report on experiments with different kernels for both of these implementations and with different representations of the data, including binary vectors, tf-idf representation and a modification called "Hadamard" representation. Then we compared it with one-class versions of the algorithms prototype (Rocchio), nearest neighbor, naive Bayes, and finally a natural one-class neural network classification method based on "bottleneck" compression generated filters.The SVM approach as represented by Schoelkopf was superior to all the methods except the neural network one, where it was, although occasionally worse, essentially comparable. However, the SVM methods turned out to be quite sensitive to the choice of representation and kernel in ways which are not well understood; therefore, for the time being leaving the neural network approach as the most robust.
Effects of Nitrogen Application Rate on the Yields, Nutritive Value and Silage Fermentation Quality of Whole-crop Wheat

Whole-crop wheat (Triticum aestivum L.) as forage has been extensively used in the world. In this study, the effects of N application rates on the yields, nutritive value and silage quality were investigated. The N application rates were 0, 75, 150, 225, and 300 kg/ha. The research results indicated that the dry matter yield of whole-crop wheat increased significantly with increasing N rate up to 150 kg/ha, and then leveled off. The crude protein content and in vitro dry matter digestibility of whole-crop wheat increased significantly with increasing N up to 225 kg/ha, while they no longer increased at N 300 kg/ha. On the contrary, the content of various fibers tended to decrease with the increase of N application. The content of lactic acid, acetic acid and propionic acid in silages increased with the increase of N rate (p<0.05). The ammonia-N content of silages with higher N application rates (≥225 kg/ha) was significantly higher than that with lower N application rates (≤150 kg/ha). Whole-crop wheat applied with high levels of N accumulated more nitrate-N. In conclusion, taking account of yields, nutritive value, silage quality and safety, the optimum N application to whole-crop wheat should be about 150 kg/ha at the present experiment conditions.
How Humans Reach: Distinct Cortical Systems for Central and Peripheral Vision

Lesions of the posterior parietal cortex in humans can produce a specific disruption of visually guided hand movements termed optic ataxia. The fact that the deficit mainly occurs in peripheral vision suggests that reaching in foveal and extrafoveal vision relies on two different anatomical substrates. Using fMRI in healthy subjects, the authors demonstrated the existence of two systems, differently modulated by the two reaching conditions. Reaching in central vision involves a restricted network, including the medial intraparietal sulcus (mIPS) and the caudal part of the dorsal premotor cortex (PMd). Reaching in peripheral vision engages a more extensive network, including the parieto-occipital junction (POJ). Interestingly, POJ corresponds to the site of the lesion overlap that the authors recently found to be responsible for optic ataxia. These two sets of results converge to show that there is not a unique cortical network for reaching control but instead two systems engaged in reaching to targets in the central and peripheral visual field.
Plans in Cooperation Logics : a modular approach

We develop a logical framework to model how agents can cooperate in order to ensure a certain state of affairs. We extend previous work on this issue by adding an explicit planning language to the object language. The resulting logical system combines reasoning about agents and groups of agents, their plans, and the effect of those plans, and becomes quite complex. To reduce this complexity, we show how the model can be defined by two separate modules: one module describes how plans affect the environment, another module describes how a group of agents can cooperate in order execute a plan. We can combine these models to obtain a new model to reason about the ability of groups of agents to use their plans to obtain certain results. What we gain with respect to earlier systems for reasoning about group ability, such as ATL, apart from handling different problems separately, is the possibility to explicitly describe by means of which plans agents obtain some outcomes.
The Beginnings of Music for a Lifetime: Survey of Musical Practices in Wisconsin Preschools

During the past ten years, increasing interest in the welfare of the preschool child has led music education organizations and teachers to examine their own philosophies and practices concerning music in the life of the young child. The MENC (1990) Future Directions Statement directs music educators to "increase the amount and quality of music education in preschools, day care centers, and kindergartens. " Implicit in this goal is the assumption that the amount and quality of music in such settings are known. During this same decade, early childhood organizations have acknowledged the importance of music in defining developmentally appropriate practice for young children as that which includes experience in singing, listening to music of various cultures, and moving and engaging in rhythmic play with simple rhythm instruments (Bredenkamp, 1987). These recommendations take the form of policy when articulated as accredited standards to address curriculum and selection of activities emphasizing "creative expression and appreciation for the arts" (National Association for the Education of Young Children, 1991, p. 23). The extent to which these policies are considered or
Síndrome de burnout y calidad de vida profesional percibida según estilos de personalidad en profesores de educación primaria

espanolEl objetivo del presente estudio es analizar los niveles del sindrome de quemarse por el trabajo o Burnout (SB) y la percepcion de calidad de vida profesional (CVP) en funcion de la tipologia y/o estilos de personalidad de Torgensen (1995) y algunas variables sociodemograficas y sociolaborales. Participaron 212 profesores de educacion primaria. Se utilizo una estrategia asociativa de tipo comparativo transversal aplicando el Inventario de los Cinco Factores (NEO-FFI), el Cuestionario de Estar Quemado por el Trabajo (CESQT) y el Cuestionario de Vida Profesional (CVP-35). Se concluye que el estilo de personalidad esta relacionada al SB, de modo que los profesores con personalidad Tipo Inseguro puntuan mas alto en las escalas de Indolencia y Culpa; y los Tipo Empresario presentan mayor puntuacion en la escala de Ilusion por el trabajo y menor en la de Indolencia. Respecto al sexo, los hombres presentan mayores puntuaciones en las escalas de Indolencia y Culpa, mientras las mujeres obtienen mayores puntaciones en la de Ilusion por el trabajo. EnglishThe main goal of the present study is to analyze the burnout syndrome levels (SB) and the perception of the professional quality of life (CVP) according to the typology and/or personality styles of Torgensen (1995) and some sociodemographic and socio-occupational variables. 212 primary school teachers participated. An associative strategy of transversal comparative type was used administering the Inventory of the Five Factors (NEO-FFI), the Questionnaire of Being Burned for Work (CESQT) and the Professional Life Questionnaire (CVP-35). It is concluded that the personality style is related to SB, being the teachers with Insecure Type personality, who score higher in the scales of Indolence and Guilt; and the Entrepreneurial Type who has the highest score in the motivation for Work scale and lowest in the Indolence scale. Regarding genders, men present higher scores in Indolence and Guilt, while women obtain higher scores in motivation for work.
A New Efficient Approach for Variable Selection Based on Multiregression: Prediction of Gas Chromatographic Retention Times and Response Factors

The selection of the most relevant variable is a frequent problem in the analysis of chemical data, especially now considering the large amounts of data created by the increased computer power and analytical resolution. A novel procedure for variable selection based on multiregression (MR) analysis is developed and applied to the quantitative structure−property relationship (QSPR) modeling of gas chromatographic retention times tR and Dietz response factors RF on 152 diverse chemical compounds. Using 296 descriptors generated by the CODESSA program, “absolutely the best” linear MR models containing from 1 to 5 descriptors were first selected (∼2 × 1010 models were checked), and then “the best” linear stepwise MR models with six and seven descriptors were obtained through “i by i” stepwise selection. In this paper i was varied from 1 to 4, so that in each next step i descriptors were added to the previously selected descriptors. Nonlinear models were developed by the inclusion of cross-products of initial .
Iterative multiuser detection with soft feedback with a subsequent stage utilizing Hopfield networks for error search and correction

In this paper, a second stage for algorithms applying iterative soft decision interference cancellation (ISDIC) (R. R. Muller and J.B. Huber, 1998) (A. Lampe et. al., Jan., 2001) (J.F. Robler J. B. Huber Nov., 2002) and for multiuser detection is proposed performing error search and correction. Analysis by simulations shows for the considered downlink scenario that the bit error ratio of a matched filter (MF) ISDIC can he lowered by a factor of nearly 100 for high signal-to-noise ratios with the subsequent second stage approaching the performance of a more complex minimum mean-squared error (MMSE) ISDIC. Furthermore, the MMSE ISDIC can he improved by the proposed second stage by up to 0.5 dB. It is shown that the ISDIC scheme with additional second stage can approach the matched filter bound up to 1 dB for the analyzed channel and 4QAM transmission.
A Brief History of Incivility in Rural Postcolonial India: Caste, Religion, and Anthropology

Abstract Anthropological studies of Indian villages conducted in the 1950s and 1960s form a valuable archive of rural life soon after India's independence. We compare sections of that archive with recent fieldwork in the same villages in Gujarat, Madhya Pradesh, and Odisha. If we trust the ethnography of the 1950s, domestic and caste spheres were the locations of village incivility. It is noteworthy that there is no reference in the early work to the Partition of the subcontinent that had occurred just a few years before. Neither is there mention of discrimination or violence carried out in the name of religion in these locations. New fieldwork reveals a different story about the rise of wholesale religious incivility in the public sphere. Caste has not vanished, but inter-caste relations have taken on new forms. We suggest that the intersection of affirmative action policies, political parties, and the systematic penetration of Hindu nationalist organizations has been crucial in the remaking of rural India.
Hystricognathy vs Sciurognathy in the Rodent Jaw: A New Morphometric Assessment of Hystricognathy Applied to the Living Fossil Laonastes (Diatomyidae)

While exceptional for an intense diversification of lineages, the evolutionary history of the order Rodentia comprises only a limited number of morphological morphotypes for the mandible. This situation could partly explain the intense debates about the taxonomic position of the latest described member of this clade, the Laotian rock rat Laonastes aenigmamus (Diatomyidae). This discovery has re-launched the debate on the definition of the Hystricognathi suborder identified using the angle of the jaw relative to the plane of the incisors. Our study aims to end this ambiguity. For clarity, it became necessary to revisit the entire morphological diversity of the mandible in extant and extinct rodents. However, current and past rodent diversity brings out the limitations of the qualitative descriptive approach and highlights the need for a quantitative approach. Here, we present the first descriptive comparison of the masticatory apparatus within the Ctenohystrica clade, in combining classic comparative anatomy with morphometrical methods. First, we quantified the shape of the mandible in rodents using 3D landmarks. Then, the analysis of osteological features was compared to myological features in order to understand the biomechanical origin of this morphological diversity. Among the morphological variation observed, the mandible of Laonastes aenigmamus displays an intermediate association of features that could be considered neither as sciurognathous nor as hystricognathous.
Generative fatherhood and children’s future civic engagement: A conceptual model of the relationship between paternal engagement and child’s developing prosocial skills

ABSTRACT Socio-emotional readiness for civic activities is necessary for young children emerging from their infant-toddler years. Cognitive skills and emotional regulation are essential to learning about one’s society and one’s role in society-at-large. When mothers and fathers are consistently emotionally present in the lives of their children, the children demonstrate prosocial outcomes in cognition, emotional regulation and social behaviors to promote socio-emotional readiness for civic activities or civic readiness. In particular, the presence of one’s father satisfies affiliative needs as the father serves as more a socializer of child to society-at-large. Generative fathering emerges from the concept of “emotional paternity. ” When fathers (birth, childrearing or cultural) are physically and emotionally present in the lives of the children on a consistent basis, children are able to demonstrate prosocial outcomes such as higher cognition, increased emotional regulation and improved social behavior. The purpose of this article is to provide a conceptual model on the relationship between paternal engagement in child-focused activities and a young child’s early presentation of prosocial behaviors that serve as building blocks to one’s future civic engagement.
Judging up and down.

In Experiment I subjects were asked to judge whether an arrow was pointing up or pointing down at various heights inside a surrounding rectangle. They were faster on an arrow pointing up the higher it was in the rectangle, and they were faster on an arrow pointing down the lower it was in the rectangle. Experiments 2, 3, and 4 were designed to test sources for this"congruity effect. " The intrusive height information for each arrow was assumed to facilitate or interfere with (a) the activation of the correct motor response; (b) the maintenance of the implicit instruction "Is it pointing up, or is it pointing down? "; or (c) the selection of the criterial perceptual information as a basis for the response. All three experiments were consistent with c, but not with a or b. Indeed, the results contrasted with previous demonstrations of the Stroop effect in certain critical features.
Adaptive mutation: General mutagenesis is not a programmed response to stress but results from rare coamplification of dinB with lac

In a particular genetic system, selection stimulates reversion of a lac mutation and causes genome-wide mutagenesis (adaptive mutation). Selection allows rare plated cells with a duplication of the leaky lac allele to initiate clones within which further lac amplification improves growth rate. Growth and amplification add mutational targets to each clone and thereby increase the likelihood of reversion. We suggest that general mutagenesis occurs only in clones whose lac amplification includes the nearby dinB+ gene (for error-prone DNA polymerase IV). Thus mutagenesis is not a programmed response to stress but a side effect of amplification in a few clones; it is not central to the effect of selection on reversion.
