Measures of success in projects implementing enterprise resource planning

The purpose of this research is to examine the existing literature of enterprise resource planning (ERP) system implementation, provide a systematic compilation of success measures, and develop a full taxonomy of success measures to assess ERP system implementation projects. This study compiled literature that highlighted possible references to success measures for ERP implementation projects. Since the intention of this study is to reach a depth of understanding of the various success measures already recognised by other researchers, 'content analysis' was used as an appropriate methodology. By analysing all success measures mentioned in literature, taxonomy of ERP implementation success measures was developed. Eleven success measures were identified, which is then categorised into four main categories. Literature was collected from selected databases and journals from 1999 to 2010. This study is significant because the taxonomy helps us to organise our knowledge. The taxonomy can facilitate researchers to make their search easier by assigning success measures to a category and defining relationships between those categories. The output of this research will help future researchers to enhance detection of related studies in the literature review phase of their work.
Does Bringing Out the Candidate Bring Out the Votes?

Scholars find that party mobilization efforts reliably increase voter turnout. Although many different forms of mobilization have been studied, one of the oldest—candidate campaigning—has not. This article examines the mobilizing potential of candidate campaign appearances in presidential elections. Analyzing aggregate election returns, I show that campaign visits can measurably increase both turnout and partisan vote percentages. The effects are often contingent, though, on how frequently candidates visit a particular area and on the timing of the campaign visits.
Risk factors and presentations of periventricular venous infarction vs arterial presumed perinatal ischemic stroke.

OBJECTIVE To determine whether clinical presentations and risk factor profiles differ between periventricular venous infarction (PVI) and arterial presumed perinatal ischemic stroke (APPIS). DESIGN Retrospective cohort study. PARTICIPANTS A total of 59 children with presumed perinatal ischemic stroke (PPIS) from the SickKids Children's Stroke Program who were carried to term (63% boys). SETTING Single tertiary care center subspecialty program. INTERVENTIONS Participants had validated magnetic resonance imaging classification to define PVI and APPIS subgroups. MAIN OUTCOME MEASURES Clinical presentations, times to parental and physician concern, age at diagnosis, and standardized risk factor evaluations including maternal, fetal, obstetrical, neonatal, and prothrombotic variables. Patients with PVI and APPIS were compared using chi(2) or Fisher exact tests and Wilcoxon rank sum or Mann-Whitney U tests. RESULTS A total of 12 children (20%) had PVI and 47 (80%) had APPIS. Median parental concern was 5 months, with delays to physician concern (7 months) and diagnosis (12 months). Delays were longer in PVI cases compared with APPIS (P = .002). Most presented with asymmetrical motor development but children with APPIS were more likely to present with seizures or nonmotor delays (P = .01). Children with APPIS were more likely to have acute perinatal risk factors (66% vs 17%; P = .002) including fetal distress, emergency caesarian section, or neonatal resuscitation. Cardiac evaluations were unremarkable. Prothrombotic abnormalities were common (44%) including protein S deficiency, lupus anticoagulant, and elevated factor IX but were comparable between APPIS and PVI subgroups. CONCLUSIONS Diagnosis of PPIS is often delayed. The association of acute perinatal risk factors with APPIS compared with PVI supports distinct timing of these diseases. Prospective, case-control risk factor studies of PPIS subtypes are required to develop prevention strategies.
Citrus Peel Use Is Associated With Reduced Risk of Squamous Cell Carcinoma of the Skin

Limonene has demonstrated efficacy in preclinical models of breast and colon cancers. The principal sources of d-limonene are the oils of orange, grapefruit, and lemon. The present case-control study was designed to determine the usual citrus consumption patterns of an older Southwestern population and to then evaluate how this citrus consumption varied with history of squamous cell carcinoma (SCC) of the skin. In this Arizona population, 64.3% and 74.5% of the respondents reported weekly consumption of citrus fruits and citrus juices, respectively. Orange juice (78.5%), orange (74.3%), and grapefruit (65.3%) were the predominant varieties of citrus consumed. Peel consumption was not uncommon, with 34.7% of all subjects reporting citrus peel use. We found no association between the overall consumption of citrus fruits [odds ratio (OR) = 0.99, 95% confidence interval (CI) = 0.73-1.32] or citrus juices (OR = 0.97, 95% CI = 0.71-1.31) and skin SCC. However, the most striking feature was the protection purported by citrus peel consumption (OR = 0.66, 95% CI = 0.45-0.95). Moreover, there was a dose-response relationship between higher citrus peel in the diet and degree of risk lowering. This is the first study to explore the relationship between citrus peel consumption and human cancers. Our results show that peel consumption, the major source of dietary d-limonene, is not uncommon and may have a potential protective effect in relation to skin SCC. Further studies with large sample sizes are needed to more completely evaluate the interrelationships between peel intake, bioavailability of d-limonene, and other lifestyle factors.
Supply chain management for sustainable products – insights from research applying mixed methodologies

The significant growth in the academic literature on sustainable supply chain management (SSCM) can best be seen by the fact that three review papers have been published since 2007. In line with this, the question emerged – what distinguishes sustainable supply chain management from ‘conventional’ supply chain management? Here, the strategy of supply chain management for sustainable products proposed by Seuring and Muller (2008a) will be discussed. Against this background, this paper aims to develop a theory for sustainable supply chain management. While other contributions are taken into account, this will be primarily based on our own research spanning about 10 years and using multiple research methods. The empirical methods employed include: (1) case studies, (2) action research, (3) Delphi study, (4) survey research, and (5) literature reviews based on content analysis. The paper will provide insights into what was learned from the different research projects and how this has helped to gain a better and wider understanding of the field. This is discussed further by presenting hypotheses which should help to further advance the theory of supply chain management for sustainable products.

GWAS of Dental Caries Patterns in the Permanent Dentition

The importance of susceptibility genes in the risk for dental caries has been clearly established. While many candidate caries genes have been proposed, to date, few of them have been rigorously validated through observational and experimental studies. Moreover, most genetic epidemiological studies have analyzed global caries phenotypes that ignore the possibility that genes may exert differential effects across tooth surfaces of the dentition. Therefore, we performed genome-wide association studies (GWAS) of 5 novel dental caries phenotypes (developed by clustering the permanent dentition into categories of tooth surfaces based on co-occurrence of caries) to nominate new candidate caries genes. GWAS was performed in 920 self-reported white participants, aged 18 to 75 years, with genotype data on 518,997 genetic variants. We identified a significant genetic association between dental caries of the anterior mandibular teeth and LYZL2 (p value = 9e-9), which codes a bacteriolytic agent thought to be involved in host defense. We also identified a significant genetic association between caries of the mid- dentition tooth surfaces and AJAP1 (p value = 2e-8), a gene possibly involved in tooth development. Suggestive genetic associations were also observed for ABCG2, PKD2, the dentin/bone SCPP sub-family, EDNRA, TJFBR1, NKX2-3, IFT88, TWSG1, IL17D, and SMAD7 (p values < 7e-6). We nominate these novel genes for future study.
Quantum-well laser with integrated passive waveguide fabricated by neutral impurity disordering

Double quantum-well lasers have been fabricated with an integrated low-loss waveguide in which the quantum wells have been intermixed by neutral impurity disordering. Threshold currents of devices with integrated 600- mu m passive guides show an increase of less than 10% over normal Fabry-Perot lasers of the same active length, confirming that the propagation loss in the passive wavelength is significantly reduced by disordering to 4.5+or-2 cm/sup -1/. Comparison with unimplanted devices suggests that the implanted dopant also passivates the waveguide electrically. <<ETX>>
Differential Gene Regulation in Fibroblasts in Co-culture with Keratinocytes and Head and Neck SCC Cells.

BACKGROUND While carcinoma-associated fibroblasts (CAFs) support tumorigenesis, normal tissue fibroblasts suppress tumor progression. Mechanisms behind conversion of fibroblasts into a CAF phenotype are largely unrevealed. MATERIALS AND METHODS Transwell co-cultures with fibroblasts in collagen gels and squamous-cell carcinoma (SCC) cells or normal oral keratinocytes (NOKs) in inserts. Differences in fibroblast global gene expression were analyzed using Affymetrix arrays and subsequent functional annotation and cluster analysis, as well as gene set enrichment analysis were performed. RESULTS There were 52 up-regulated and 30 down-regulated transcript IDs (>2-fold, p<0.05) in fibroblasts co-cultured with SCC compared to NOKs. Functional analysis demonstrated an enrichment of collagen-related genes. There were similarities with gene sets reflecting a non-specific, innate-type response with activation of both interferon pathways and connective tissue turnover. CONCLUSION There were distinct differences in fibroblast gene expression between the co-culture types. Many were in genes related to an innate-type of response and to connective tissue turnover.
Distributed compressed sensing algorithms: Completing the puzzle

Reconstructing compressed sensing signals involves solving an optimization problem. An example is Basis Pursuit (BP) [1], which is applicable only in noise-free scenarios. In noisy scenarios, either the Basis Pursuit Denoising (BPDN) [1] or the Noise-Aware BP (NABP) [2] can be used. Consider a distributed scenario where the dictionary matrix and the vector of observations are spread over the nodes of a network. We solve the following open problem: design distributed algorithms that solve BPDN with a column partition, i.e., when each node knows only some columns of the dictionary matrix, and that solve NABP with a row partition, i.e., when each node knows only some rows of the dictionary matrix and the corresponding observations. Our approach manipulates these problems so that a recent general-purpose algorithm for distributed optimization can be applied.
Enhanced PET resolution by combining pinhole collimation and coincidence detection

Spatial resolution of clinical PET scanners is limited by detector design and photon non-colinearity. Although dedicated small animal PET scanners using specialized high-resolution detectors have been developed, enhancing the spatial resolution of clinical PET scanners is of interest as a more available alternative. Multi-pinhole 511 keV SPECT is capable of high spatial resolution but requires heavily shielded collimators to avoid significant background counts. A practical approach with clinical PET detectors is to combine multi-pinhole collimation with coincidence detection. In this new hybrid modality, there are three locations associated with each event, namely those of the two detected photons and the pinhole aperture. These three locations over-determine the line of response and provide redundant information that is superior to coincidence detection or pinhole collimation alone. Multi-pinhole collimation provides high resolution and avoids non-colinearity error but is subject to collimator penetration and artifacts from overlapping projections. However the coincidence information, though at lower resolution, is valuable for determining whether the photon passed near a pinhole within the cone acceptance angle and for identifying through which pinhole the photon passed. This information allows most photons penetrating through the collimator to be rejected and avoids overlapping projections. With much improved event rejection, a collimator with minimal shielding may be used, and a lightweight add-on collimator for high resolution imaging is feasible for use with a clinical PET scanner. Monte Carlo simulations were performed of a 18F hot rods phantom and a 54-pinhole unfocused whole-body mouse collimator with a clinical PET scanner. Based on coincidence information and pinhole geometry, events were accepted or rejected, and pinhole-specific crystal-map projections were generated. Tomographic images then were reconstructed using a conventional pinhole SPECT algorithm. Hot rods of 1.4 mm diameter were resolved easily in a simulated phantom. System sensitivity was 0.09% for a simulated 70-mm line source corresponding to the NEMA NU-4 mouse phantom. Higher resolution is expected with further optimization of pinhole design, and higher sensitivity is expected with a focused and denser pinhole configuration. The simulations demonstrate high spatial resolution and feasibility of small animal imaging with an add-on multi-pinhole collimator for a clinical PET scanner. Further work is needed to develop geometric calibration and quantitative data corrections and, eventually, to construct a prototype device and produce images with physical phantoms.
Improving Side-Effect Analysis with Lazy Access Path Resolving

For scalability, many side-effect analysis methods choose inclusion-based context-insensitive (IBCI) pointer analysis as their basis. However, such a pointer analysis is known to be imprecise, which often results in over-conservative side-effect sets. In this paper, we present a lightweight approach that exploits lazy access path resolving to improve the precision of side-effect analysis under IBCI pointer analysis. The approach partly represents and propagates side-effects in the access path form with the help of interstatement must aliases. All access paths can finally be resolved to the accessed locations, but during the side-effect propagation phase, an access path will never be resolved as long as it could be mapped to another access path in the caller. Since in inclusion-based points-to analysis, points-to sets of variables in the callers tend to be smaller than the ones in the callees, such lazy resolving mechanism can lead to more precision. The experimental results show that the lazy access path resolving approach is effective in improving the precision of IBCI pointer analysis based side-effect analysis methods.
Reflecting on the Design and Implementation Issues of Virtual Environments

We present a candid reflection on the issues surrounding virtual environment design and implementation (VEDI) in order to: (1) motivate the topic as a researchworthy undertaking, and (2) attempt a comprehensive listing of impeding VEDI issues so they can be addressed. In order to structure this reflection, an idealized model of VEDI is presented. This model, investigated using mixed methods, resulted in 67 distinct issues along the model's transitions and pathways. These were clustered into 11 themes and used to support five VEDI research challenges.
Dealing with the cost of illness: The experience of four villages in Lao PDR

This paper analyses household coping strategies for illness in four Lao villages. The villagers dealt with health expenditure themselves, using coping mechanisms which drew mainly on social networks within the community. They strongly believed in the principle of paying user fees and did not consider exemption from fees an option. A total of 12 households (6 per cent of households) faced catastrophic expenditure arising from healthcare payments. The national policy on exemptions did not protect the poor and the study demonstrates that there is an urgent need for the government to improve the design and implementation of exemptions or reform the policy on subsidising health care.

Unified Analytical Volume Distribution of Poisson-Delaunay Simplex and Its Application to Coordinated Multi-Point Transmission

For Poisson-Delaunay triangulations in <inline-formula> <tex-math notation="LaTeX">$d$ </tex-math></inline-formula>-dimensional Euclidean space <inline-formula> <tex-math notation="LaTeX">$\mathbb {R}^{d}$ </tex-math></inline-formula>, a structured and computationally efficient form of the probability density function (PDF) of the volume of a typical cell is analytically derived in this paper. In particular, the ensuing PDF and the corresponding cumulative density function are exact and unified, applicable to spaces of arbitrary dimension (<inline-formula> <tex-math notation="LaTeX">$d \ge 1$ </tex-math></inline-formula>). Then, the special cases and shape characteristics of the resulting PDF are thoroughly examined. Finally, various applications of the obtained distribution functions are outlined and, in particular, a novel coordinated multi-point transmission scheme based on Poisson-Delaunay triangulation is developed and the pertinent void cell effect is precisely evaluated by using the obtained distribution functions.
Labor Supply Responses and Welfare Effects of Tax Reforms

During the late 1980s and early 1990s, taxation of wage income has undergone a change towards a proportional tax regime in many countries. The authors' analysis shows that gradual tax reforms in Norway may have removed some of the distortions on worker behavior. Moreover, the authors find that proportional taxes may reduce the inequality in the distribution of disposable household income. Yet, when the distributional consequences are related to changes in individual welfare, they find that rich households may benefit far more than households at the other tail of the income distribution because they earn more without any significant increase in effort.

Permanent and Temporary Components of Stock Prices: Evidence from Assessing Macroeconomic Shocks

This paper outlines a simple macro model with overlapping wage contracts to investigate how the temporary and permanent components of stock price movements may be related to aggregate macroeconomic supply and demand disturbances. In the content of the model, we show that aggregate demand shocks have only temporary effects on real stock prices, while supply shocks may affect the level of real stock prices permanently. Moreover, the temporary component in U.S. stock prices, identified by placing appropriate structural restrictions on a vector autoregressive system estimated for the postwar period, is statistically significant. This evidence supports the mean-reversion hypothesis that stock prices are not pure random walks. The finding is robust to the choice of variables used in the vector autoregressive system and periodicity.
The Land and Water Integration Decision Support System

Integration of data and comp onent models describing habitat -based land use, non -point source pollutants transport, and water and soil quality forms the decision support developme nt processes to assist policy makers in examining management options for dealing with the impacts of land use on water for agricultural issues in Canada. The land and water integration decision support system emphasizes on scale consistency, scenario gaming and testing, pollutant source tracing and optimal solutions. Example s of a watershed -based decision support system o n water quality impact were presented as part of an assessment for the evaluation of best management practice options for future agricultural intensification scenario.
Liability for Harm or Restitution for Benefit?

THE choice between liability (negative incentive) rules and restitution (positive incentive) rules presupposes important judgments about the distribution and protection of entitlements. This paper uses economic theory to provide a systematic framework for analyzing these fundamental entitlement issues in law and political philosophy. It develops a model that enables us to answer a wide array of questions, such as, Why do ordinary economic markets tend to rely on positive incentives (the carrot), while governments tend to rely on coercion (the stick)? Should the owner of a natural lake be liable for damage to a downstream homeowner if the lake owner does not build a dam to prevent flooding, or should the downstream homeowner be liable to the owner of the lake for the benefit of building the dam? Should a passerby be liable to another person lying unconscious on a railroad track for nonrescue, or should the unconscious person be liable for being rescued? If coastal land is rezoned so that development can no longer take place, should the owner of the land be compensated for diminished value? Should a polluter be taxed for creating too much pollution or subsidized for undertaking pollution control? Should children be punished for not doing their chores or be rewarded for doing them? Why is productive labor rewarded in capitalist societies while nonproductive labor is punished in feudal societies?
I don ’ t see what you are saying : reduced visual influence on audiovisual speech integration in children with Specific Language Impairment

The impact of language impairment on audio-visual integration of speech in noise is examined here by testing the influence of the degradation of the auditory and the visual speech cue. Fourteen children with specific language impairment (SLI) and 14 age-matched children with typical language development (TLD) had to identify /aCa/ syllables presented in auditory only (AO), visual only (VO) and audiovisual (AV) congruent and incongruent (McGurk stimuli) conditions, embedded either in stationary noise (ST) or amplitude modulated noise (AM), in a masking release paradigm. Visual cues were either reduced (VR) or clear (VCL). In the AO modality, children with SLI had poorer performance than TLD children in AM noise but not in ST noise, leading to a weaker masking release effect. In VO modality, children with SLI had weaker performance both in VCL and VR conditions. Analyses revealed reduced AV gains in children with SLI compared to control children. In the McGurk trials, SLI children showed a decreased influence of visual cues on AV perception in the SLI group compared to the TLD group. Data analysis in the framework of the FuzzyLogical Model of Perception suggested that children with SLI had preserved integration abilities; the differences with TLD children were rather due to differences in the unisensory modalities. An increased weight of audition in the VR condition compared to the VCL condition was observed in both groups, suggesting that participants awarded more weight to audition when the visual input was degraded.
