A Computer Simulation Test of the M-Form Hypothesis

This research began in the summer 1978 with the support of the Danish Social Science Research Council. Thanks go to Ms. Margaret Figueroa, the first author's research assistant. A grant from the Duke University Research Council supported her efforts. This research tests Williamson's M-form hypothesis which posits an information imperative of organizational form instead of a technology imperative. The experimental design is a two-by-two factorial design. Two levels of decomposability of technology are the values for the first variable. The multidivisional form (M-form) and the unitary (U-form) are the values for the second variable. The data are generated from a perturbed decomposed mathematical programming model that is coordinated by a Dantzig-Wolfe pricing approach. The data are analyzed using the Kruskal-Wallis nonparametric approach. The results substantiate Williamson's hypothesis that the M-form of organization is superior to the U-form organization alternative. For each of the two levels of decomposability of technology, the M-form of organization yields higher profit solutions than the U-form.
Comparison of FPGA and ASIC Implementation of a Linear Congruence Solver

Residual processor (RP) is a dedicated hardware for solution of sets of linear congruences. RPs are parts of a larger modular system for error-free solution of linear equations in residue arithmetic. We present new FPGA and ASIC RP implementations, focusing mainly on their memory units being a bottleneck of the calculation and therefore determining the efficiency of the system. First, we choose an FPGA to easily test the functionality of our implementation, then we do the same in ASIC, and finally we compare both implementations together. The experimental FPGA results are obtained for Xilinx Virtex 6, while the ASIC results are obtained from Synopsys tools with a 130 nm standard cell library. Results also present a maximum matrix dimension fitting directly into the FPGA and achieved speed as a function of the dimension.
Enjoyment as the Link between Leisure and Physical Activity

Iam a runner. I used to think that the label of runner was stretching my capabilities, but since I have run for over 25 years, I think I can claim this identity. Two years ago during a 10K road race, I passed a young woman around mile four. As I ran by, she said, "I hope I can run like you when I get old:' At first, I felt insulted that she was highlighting my age. However, after the race was over, I thought more about her comment and reflected on it in my journal:
Effects of Aeration Cycles on Nitrifying Bacterial Populations and Nitrogen Removal in Intermittently Aerated Reactors

ABSTRACT The effects of the lengths of aeration and nonaeration periods on nitrogen removal and the nitrifying bacterial community structure were assessed in intermittently aerated (IA) reactors treating digested swine wastewater. Five IA reactors were operated in parallel with different aeration-to-nonaeration time ratios (ANA). Populations of ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB) were monitored using 16S rRNA slot blot hybridizations. AOB species diversity was assessed using amoA gene denaturant gradient gel electrophoresis. Nitrosomonas and Nitrosococcus mobilis were the dominant AOB and Nitrospira spp. were the dominant NOB in all reactors, although Nitrosospira and Nitrobacter were also detected at lower levels. Reactors operated with the shortest aeration time (30 min) showed the highest Nitrosospira rRNA levels, and reactors operated with the longest anoxic periods (3 and 4 h) showed the lowest levels of Nitrobacter, compared to the other reactors. Nitrosomonas sp. strain Nm107 was detected in all reactors, regardless of the reactor's performance. Close relatives of Nitrosomonas europaea, Nitrosomonas sp. strain ENI-11, and Nitrosospira multiformis were occasionally detected in all reactors. Biomass fractions of AOB and effluent ammonia concentrations were not significantly different among the reactors. NOB were more sensitive than AOB to long nonaeration periods, as nitrite accumulation and lower total NOB rRNA levels were observed for an ANA of 1 h:4 h. The reactor with the longest nonaeration time of 4 h performed partial nitrification, followed by denitrification via nitrite, whereas the other reactors removed nitrogen through traditional nitrification and denitrification via nitrate. Superior ammonia removal efficiencies were not associated with levels of specific AOB species or with higher AOB species diversity.
Serum concentrations of zinc and selenium in elderly people : results in healthy nonagenarians / centenarians

Trace elements such as zinc (Zn) and selenium (Se) play an important role in maintaining the metabolic homeostasis in elderly people and the risk of de®ciency seems to increase in proportion to the age. Zn and Se concentrations, as indices of the micronutrient status in healthy subjects over 90 years, are scarcely analyzed and could represent a model for studying the physiology of successful aging. Our aim was to investigate Zn and Se concentrations in the healthy persons over the age of 90 years. One hundred and ®fty two subjects volunteered for the study. They were divided into two groups: 90 non-institutionalized nonagenarians/centenarians (91±110 years) (group A) and 62 elderly subjects (60±90 years) used for comparison (group B). Serum concentrations of Zn and Se were determined, respectively, by ̄ame atomic absorption spectrophotometry (FAAS) and electrothermal atomic absorption spectrophotometry (ETAAS). The effect of age and sex on ion concentrations was investigated. Mean values ^ standard deviation of Zn and Se concentrations in the group A were 11.97 ^ 2.00 and 0.87 ^ 0.28 mmol/l, respectively. A signi®cant decrease of Se and Zn values was demonstrated in group A, when compared with group B, in both males and females. However, 84.4% of the `healthy' nonagenarians/centerians had both Zn and Se concentrations equal to or greater than the lowest values of the elderly group and only 3.3% of cases showed both Zn and Se de®ciencies. Consequently, a prospective and follow-up evaluation of Zn and Se could be proposed as a good index for a correct monitoring of the micronutrient de®ciencies, that could represent an early sign of disease. q 2001 Elsevier Science Inc.

Surfing with Fun

The paper presents a formalization of web sites based on functional programming (FP) and graphs. More precisely, it explains how FP can be used to infer and to generate web pages from a data model, or to embed a query language (helpful to search a precise information). As a consequence, the paper also proposes a generic web site to be configured with a (meta)model of a domain, and its application to the CCAlps European project.
Taking a Turn Toward the Masculine: The Impact of Mortality Salience on Implicit Leadership Theories

The present research investigates the influence of subtle death-related thoughts (i.e., mortality salience) on people's images of effective leaders (i.e., their implicit leadership theories [ILTs]). We test the prediction that mortality salience will change the content of these implicit theories to be more gender stereotypical such that individuals will conceive of effective leaders in a significantly more masculine, or agentic, manner. To test this prediction, we assessed the communal and agentic components of participants' ILTs after they were presented with a mortality salience or control manipulation. Results show that priming individuals to think about their mortality with two open-ended questions resulted in a significant shift in their ILTs such that an effective leader is described in significantly more agentic terms compared to the control condition. This masculine shift in people's ILTs was demonstrated in both women and men, and mortality salience did not influence perceptions of effective leaders' communal traits. This work contributes to research on gender bias in leadership, ILTs, and terror management theory and has implications for female leaders.
Corticosteroids for treating dengue shock syndrome.

BACKGROUND Dengue shock syndrome is the most severe from of dengue haemorrhagic fever, one of the leading causes of death in children. Observational studies have suggested corticosteroids may benefit people with dengue shock syndrome. OBJECTIVES To compare corticosteroids with placebo or no corticosteroids for treating dengue shock syndrome. SEARCH STRATEGY We searched the Cochrane Infectious Disease Group Specialized Register (January 2006), CENTRAL (The Cochrane Library 2005, Issue 4), MEDLINE (1966 to January 2006), EMBASE, (1974 to January 2006), LILACS (1982 to January 2006), and reference lists. We also contacted researchers. SELECTION CRITERIA Randomized and quasi-randomized controlled trials comparing corticosteroids with no corticosteroids or placebo in people diagnosed with dengue shock syndrome. DATA COLLECTION AND ANALYSIS Two authors independently applied the inclusion criteria, extracted data, and assessed methodological quality. We calculated the relative risk (RR) for dichotomous data and weighted mean difference for continuous data, and presented them with 95% confidence intervals (CI). MAIN RESULTS Four trials involving 284 participants met the inclusion criteria. Corticosteroids were no more effective than placebo or no treatment for reducing the number of deaths (RR 0.68, 95% CI 0.42 to 1.11; 284 participants, 4 trials), the need for blood transfusion (RR 1.08, 0.52 to 2.24; 89 participants, 2 trials), or the number of serious complications (convulsions and pulmonary haemorrhage) as reported in one trial (63 participants). AUTHORS' CONCLUSIONS There is insufficient evidence to justify the use of corticosteroids in managing dengue shock syndrome. As corticosteroids can potentially do harm, clinicians should not use them unless they are participating in a randomized controlled trial comparing corticosteroids with placebo.
Developing phonological awareness: Is there a bilingual advantage?

Three studies are reported that examine the development of phonological awareness in monolingual and bilingual children between kindergarten and Grade 2. In the first study, monolingual and bilingual children performed equally well on a complex task requiring phoneme substitution. The second study replicated these results and demonstrated a significant role for the language of literacy instruction. The third study extended the research by including two groups of bilingual children and a range of phonological awareness and reading tasks. Spanish–English bilinguals performed better than English-speaking monolinguals on a phoneme segmentation task, but Chinese–English bilinguals performed worse. Other measures of phonological awareness did not differ among the three groups. The results are discussed in terms of a limit on the effect that bilingualism exerts on metalinguistic development.
Human hepatic lipase overexpression in mice induces hepatic steatosis and obesity through promoting hepatic lipogenesis and white adipose tissue lipolysis and fatty acid uptake

Human hepatic lipase (hHL) is mainly localized on the hepatocyte cell surface where it hydrolyzes lipids from remnant lipoproteins and high density lipoproteins and promotes their hepatic selective uptake. Furthermore, hepatic lipase (HL) is closely associated with obesity in multiple studies. Therefore, HL may play a key role on lipid homeostasis in liver and white adipose tissue (WAT). In the present study, we aimed to evaluate the effects of hHL expression on hepatic and white adipose triglyceride metabolism in vivo. Experiments were carried out in hHL transgenic and wild-type mice fed a Western-type diet. Triglyceride metabolism studies included β-oxidation and de novo lipogenesis in liver and WAT, hepatic triglyceride secretion, and adipose lipoprotein lipase (LPL)-mediated free fatty acid (FFA) lipolysis and influx. The expression of hHL promoted hepatic triglyceride accumulation and de novo lipogenesis without affecting triglyceride secretion, and this was associated with an upregulation of Srebf1 as well as the main genes controlling the synthesis of fatty acids. Transgenic mice also exhibited more adiposity and an increased LPL-mediated FFA influx into the WAT without affecting glucose tolerance. Our results demonstrate that hHL promoted hepatic steatosis in mice mainly by upregulating de novo lipogenesis. HL also upregulated WAT LPL and promoted triglyceride-rich lipoprotein hydrolysis and adipose FFA uptake. These data support the important role of hHL in regulating hepatic lipid homeostasis and confirm the broad cardiometabolic role of HL.
The Influence of Religiosity and Spirituality on Drinking Behaviors: Differences between Students Attending Two Southern Universities

The purpose of this study was to determine if students (n = 431) from two southern universities—one in the “buckle” of the Bible-belt, the other a southern “border” state—have different drinking behaviors depending on their religiosity and spirituality. Approximately 95% of students indicated that they had at least one drink of alcohol during their lives, with almost 82% reporting that they used alcohol in the past 30 days. Binge drinking among underage students increased every year (approximately 43% to almost 70%). Students from the buckle university had higher degrees of religiosity and spirituality and reported fewer unhealthy drinking behaviors than those from the border university. By creating a learning environment where students are encouraged to increase the spiritual dimension of health, health educators may alleviate potentially deadly consequences of alcohol.
Visual and Verbal Rhetorical Figures Under Directed Processing Versus Incidental Exposure to Advertising

This re-inquiry examines the robustness of research showing that rhetorical figures such as rhyme and metaphor can have a positive impact on consumer response to advertising. Prior empirical research explicitly directed subjects to process the ads and generally examined either visual or verbal rhetoric, but not both. We embedded ads containing visual and verbal figures in a 32-page magazine designed to be interesting to subjects and manipulated directed processing or incidental exposure to the ads. Ads with figures were recalled more often and liked better. Visual figures were more effective regardless of processing condition, whereas verbal figures performed better only when subjects were directed to process the ads.
Principles of CT: Radiation Dose and Image Quality*

This article discusses CT radiation dose, the measurement of CT dose, and CT image quality. The most commonly used dose descriptor is CT dose index, which represents the dose to a location (e.g., depth) in a scanned volume from a complete series of slices. A weighted average of the CT dose index measured at the center and periphery of dose phantoms provides a convenient single-number estimate of patient dose for a procedure, and this value (or a related indicator that includes the scanned length) is often displayed on the operator's console. CT image quality, as in most imaging, is described in terms of contrast, spatial resolution, image noise, and artifacts. A strength of CT is its ability to visualize structures of low contrast in a subject, a task that is limited primarily by noise and is therefore closely associated with radiation dose: The higher the dose contributing to the image, the less apparent is image noise and the easier it is to perceive low-contrast structures. Spatial resolution is ultimately limited by sampling, but both image noise and resolution are strongly affected by the reconstruction filter. As a result, diagnostically acceptable image quality at acceptable doses of radiation requires appropriately designed clinical protocols, including appropriate kilovolt peaks, amperages, slice thicknesses, and reconstruction filters.
A Multigene Phylogenetic Study of Clonal Diversity and Divergence in North American Strains of the Plant Pathogen Xylella fastidiosa

ABSTRACT Xylella fastidiosa is a pathogen that causes leaf scorch and related diseases in over 100 plant species, including Pierce's disease in grapevines (PD), phony peach disease (PP), plum leaf scald (PLS), and leaf scorch in almond (ALS), oak (OAK), and oleander (OLS). We used a high-resolution DNA sequence approach to investigate the evolutionary relationships, geographic variation, and divergence times among the X. fastidiosa isolates causing these diseases in North America. Using a large data set of 10 coding loci and 26 isolates, the phylogeny of X. fastidiosa defined three major clades. Two of these clades correspond to the recently identified X. fastidiosa subspecies piercei (PD and some ALS isolates) and X. fastidiosa subsp. multiplex (OAK, PP, PLS, and some ALS isolates). The third clade grouped all of the OLS isolates into a genetically distinct group, named X. fastidiosa subsp. sandyi. These well-differentiated clades indicate that, historically, X. fastidiosa has been a clonal organism. Based on their synonymous-site divergence (∼3%), these three clades probably originated more than 15,000 years ago, long before the introduction of the nonnative plants that characterize most infections. The sister clades of X. fastidiosa subsp. sandyi and X. fastidiosa subsp. piercei have synonymous-site evolutionary rates 2.9 times faster than X. fastidiosa subsp. multiplex, possibly due to generation time differences. Within X. fastidiosa subsp. multiplex, a low level (∼0.1%) of genetic differentiation indicates the recent divergence of ALS isolates from the PP, PLS, and OAK isolates due to host plant adaptation and/or allopatry. The low level of variation within the X. fastidiosa subsp. piercei and X. fastidiosa subsp. sandyi clades, despite their antiquity, suggests strong selection, possibly driven by host plant adaptation.
A symbiotic mutant of Sinorhizobium meliloti reveals a novel genetic pathway involving succinoglycan biosynthetic functions

A large‐scale screen for symbiotic mutants was carried out using the model root nodulating bacterium Sinorhizobium meliloti. Several mutations in the previously uncharacterized gene msbA2 were isolated. msbA2 encodes a member of the ATP‐binding cassette exporter family. This protein family is known to export a wide variety of compounds from bacterial cells. S. meliloti MsbA2 is required for the invasion of nodule tissue, with msbA2 mutant cells stimulating nodule primordium morphogenesis, but failing to invade plant tissue beyond the epidermal cell layer. msbA2 mutants do not exhibit any of the free‐living traits often found to correlate with symbiotic defects, suggesting that MsbA2 may take part in a specifically symbiotic function. In strains that overproduce the symbiotic signalling polysaccharide succinoglycan, loss of MsbA2 function is extremely deleterious. This synthetic lethal phenotype can be suppressed by disrupting the succinoglycan biosynthetic genes exoY or exoA. It can also be suppressed by disrupting putative glycosyltransferase‐encoding genes found upstream of msbA2. Finally, the symbiotic phenotype of a msbA2 null mutant is suppressed by secondary mutations in these upstream transferase genes, indicating that the msbA2 mutant phenotype may be caused by an inhibitory accumulation of a novel polysaccharide that is synthesized from succinoglycan precursors.
Dynamic capabilities for CSR management: towards identifying common processes

Purpose – The objective of this paper is to address the question whether and how firms can follow a standard management process to cope with emerging corporate social responsibility (CSR) challenges? Both researchers and practitioners have paid increasing attention to the question because of the rapidly evolving CSR expectations of stakeholders and the limited diffusion of CSR standardization. The question was addressed by developing a theoretical framework to explain how dynamic capabilities can contribute to effective CSR management. Design/methodology/approach – Based on 64 world-leading companies’ contemporary CSR reports, we carried out a large-scale content analysis to identify and examine the common organizational processes involved in CSR management and the dynamic capabilities underpinning those management processes. Findings – Drawing on the dynamic capabilities perspective, we demonstrate how the deployment of three dynamic capabilities for CSR management, namely, scanning, sensing and reconfiguration capabilities can help firms to meet emerging CSR requirements by following a set of common management processes. The findings demonstrate that what is more important in CSR standardization is the identification and development of the underlying dynamic capabilities and the related organizational processes and routines, rather than the detailed operational activities. Originality/value - Our study is an early attempt to examine the fundamental organizational capabilities and processes involved in CSR management from the dynamic capabilities perspective. Our research findings contribute to CSR standardization literature by providing a new theoretical perspective to better understand the capabilities enabling common CSR management processes.
PDGF‐BB increases endothelial migration and cord movements during angiogenesis in vitro

To explore direct effects of platelet‐derived growth factor (PDGF) on endothelial cells during angiogenesis in vitro, we have used cloned bovine aortic endothelial cells that spontaneously form cord structures. Recently we have shown that cells forming these endothelial cords express PDGF β‐receptors and that PDGF‐BB can contribute to cellular proliferation and cord formation. In this study we investigated whether PDGF‐induced cellular migration might also contribute to endothelial repair and angiogenesis in vitro.
The DCR Protein TTC3 Affects Differentiation and Golgi Compactness in Neurons through Specific Actin-Regulating Pathways

In neuronal cells, actin remodeling plays a well known role in neurite extension but is also deeply involved in the organization of intracellular structures, such as the Golgi apparatus. However, it is still not very clear which mechanisms may regulate actin dynamics at the different sites. In this report we show that high levels of the TTC3 protein, encoded by one of the genes of the Down Syndrome Critical Region (DCR), prevent neurite extension and disrupt Golgi compactness in differentiating primary neurons. These effects largely depend on the capability of TTC3 to promote actin polymerization through signaling pathways involving RhoA, ROCK, CIT-N and PIIa. However, the functional relationships between these molecules differ significantly if considering the TTC3 activity on neurite extension or on Golgi organization. Finally, our results reveal an unexpected stage-dependent requirement for F-actin in Golgi organization at different stages of neuronal differentiation.
Mineral Potential Prediction Using Hybrid Intelligent Approach

Predicting minerals potential helps miners in making wise decisions. In this paper, we present a computerized prototype system called GoldXplorer that enables to predict the existence and distribution of gold (aurum (Au)) at a given location with its geological and geographical factors. With its two intelligent engines based on back-propagation neural network and self-organizing map techniques, GoldXplorer helps users (geologists, investors, gold miners or individuals) to determine the gold potentials for further investigation and mining activity. For the case study, we use data sets collected from an area called Kuala Lipis in Malaysia. This set of data was supplied and verified by Malaysia Department of Minerals and Geosciences. The data consists of the location (RSOE and RSON) and all types of minerals found in the area. Two thousand sample points were used in this research and it results in eighty percent (or more) of accuracy rate. With the results produced by GoldXplorer, the potential strategic locations for gold mining may be determined. In addition, with the predicted information, future planning can be carried out so that the earth can be properly kept from any illegal mining.
