Contribution of the Regulatory Gene lemA to Field Fitness of Pseudomonas syringae pv. syringae

In Pseudomonas syringae pv. syringae, lemA is required for brown spot lesion formation on snap bean and for production of syringomycin and extracellular proteases (E. M. Hrabak and D. K. Willis, J. Bacteriol. 174: 3011-3022, 1992; E. M. Hrabak and D. K. Willis, Mol. Plant-Microbe Interact. 6:368-375, 1993; D. K. Willis, E. M. Hrabak, J. J. Rich, T. M. Barta, S. E. Lindow, and N. J. Panopoulos, Mol. Plant-Microbe Interact. 3:149-156, 1990). The lemA mutant NPS3136 (lemA1::Tn5) was previously found to be indistinguishable from its pathogenic parent B728a in its ability to grow when infiltrated into bean leaves of plants maintained under controlled environmental conditions (Willis et al., Mol. Plant-Microbe Interact. 3:149-156, 1990). We compared population sizes of NPS3136 and B728aN (a Nal(supr) clone of wild-type B728a) in two field experiments to determine the effect of inactivation of lemA on the fitness of P. syringae pv. syringae. In one experiment, the bacterial strains were spray inoculated onto the foliage of 25-day-old bean plants. In the other, seeds were inoculated at the time of planting. In both experiments, the strains were inoculated individually and coinoculated in a 1:1 ratio. NPS3136 and B728aN achieved similar large population sizes on germinating seeds. However, in association with leaves, population sizes of NPS3136 were diminished relative to those of B728aN in both experiments. Thus, lemA contributed significantly to the fitness of P. syringae pv. syringae in association with bean leaves but not on germinating seeds under field conditions. When NPS3136 was coinoculated with B728aN, the mutant behaved as it did when inoculated alone. However, population sizes of B728aN in the coinoculation treatment were much lower than those when it was inoculated alone. Inactivation of the lemA gene appeared to have rendered the mutant suppressive to B728aN.
Factors Inducing National Media Coverage for Tourism in Rural versus Urban Areas: The Role of Public Relations

ABSTRACT This study examines the relationship between media coverage patterns of rural and urban tourist spaces in Israel, the characteristics of these spaces, and the way in which public relations (PR) are conducted to promote rural tourism in those areas. Using geographical distance, population size and type of tourist products for the spatial variables, PR financial budgets and PR practice types for the PR variables, the study examines their relative importance for rural versus urban tourism promotion. Results show that ongoing professional PR is crucial for the success of rural destinations in receiving large and positive national media coverage.
Persistent Employment Instability and Fertility Intentions: The Gender-Specific Effect within Couples in Italy

Our paper adds to the growing literature on the measurement of employment instability and on that on its consequences on fertility dynamics. We argue that many of these studies disregard a crucial dimension of employment instability: its persistence (duration). It is the persistence in an unstable condition, more than the status itself, that may have the most severe consequences on subsequent family choices. In this paper, we propose an index of persistence in employment instability that synthesizes all the information inside the individual sequence of employment statuses in a single number accounting simultaneously for the duration, sequencing, intensity, and labour market circumstances. Then, we test its impact on short-term childbearing intentions, and we do this separately for women and for men as well as for different parities. The application focuses on the Italian case.
Contextual factors affecting the deployment of innovative performance measurement systems

Purpose - The purpose of this paper is to examine the association between strategy, structure and environmental uncertainty, and the design and the use of performance measurements systems. The paper provides empirical evidence on the contextual factors associated with the use of financial and non-financial measures, process and outcome measures and the deployment of innovative performance measurement systems in manufacturing business units. Design/methodology/approach - A questionnaire was sent to a random sample of 200 Canadian manufacturing organizations. Respondents were asked to indicate to which extent they use different measures. They also had to mention if they had adopted an innovative performance measurement approach such as the balanced scorecard. The questionnaire also included questions to classify organizations as prospectors, defenders or analyzers and to measure the levels of decentralization and perceived environmental uncertainty. Findings - The results show that there is a significant association between strategy, organizational structure and environmental uncertainty and the use of non-financial and process measures. They also indicate that there is an association between strategy and environmental uncertainty and the deployment of innovative performance measurement systems. Practical implications - Since the 1990s, performance measurement has become an important issue for both academics and practitioners. The professional literature has suggested that managers should design innovative performance measurement systems such as balanced scorecards that include financial and non-financial measures and also process and outcome measures. This paper provides a better understanding of the factors that affect the implementation of innovative performance measurement systems. Originality/value - The paper presents one of the few studies that provide a better understanding of the contingent factors that influence the design and the use of innovative performance measurement systems.
Value for Money and Risk in Public–Private Partnerships

Problem, research strategy, and findings: Delivering improved public services at lower cost, also known formally as value for money (VfM), is often the main rationale for procuring large infrastructure projects through public–private partnerships (PPPs). However, it is unclear whether the ex ante assessments of PPPs account for key planning concerns, including limitations on community consultation, contractual lock-ins that curtail public flexibility to make future plans, and a political preference for PPPs that may influence the way that projects are structured and evaluated. This set of questions is examined for 28 infrastructure PPPs delivered in Ontario, Canada, and interviews with18 senior political, government, and private-sector participants in the province's PPP industry. We find that transferring of construction risks from government to the private-sector partners drives VfM results, and may overvalue the extent to which planning related risks can be transferred. Takeaway for practice: PPP contract structures should permit more transparency during the project planning process and preserve the flexibility of governments to control key planning tasks such as user fees, service coordination and facility expansion. Strategies might include: the unbundling of construction and operation phases of the PPP in all but the most unique situations, the use of competitive dialogue tendering to deepen public–private collaboration earlier in the planning process, and the inclusion of contract rebalancing terms to better share rather than transfer project risks.

Theoretical examination of destination loyalty formation

Purpose – The purpose of this paper is to identify the most critical antecedents of destination loyalty formation (DLF) and to develop a series of propositions for the relationships among the antecedents of loyalty formation and their direct and indirect impacts on loyalty formation. Design/methodology/approach – This conceptual paper provides a comprehensive review of the previous studies that examined destination loyalty and posits a framework of tourist DLF titled Destination Loyalty Formation. Findings – In the proposed conceptual model, the sequential relationships among the antecedents of tourist destination loyalty postulate that previous experiences are the most influential driver that could manipulate tourist destination loyalty. Place attachment and involvement constitute the second most influential factors of DLF. In addition to the above two variables, destination image is proposed to have direct and indirect effects on perception of service quality and satisfaction. Meanwhile, service quality.
Institutional and Individual Influences on the President's Veto

This article evaluates and compares "president" and "presidency" centered explanations of presidential activity with respect to one important presidential power, the veto. Using individual bill data for nine congresses characterized by divided party government, I estimate a logistic regression model of presidential vetoes. This contrasts with previous research, which has used annual aggregate data. Using individual bill data allows controls for objectionable legislation passed by Congress and enables me to measure and compare the "propensity to veto" of different presidents. I conclude that presidential vetoes are in substantial measure caused by Congress passing objectionable bills, but that even controlling for congressional behavior, presidents exhibit strikingly different veto behavior. Ford was most prone to using the veto, and Reagan, the least. Although external factors exert great influence on the president's veto decision, the individual choices and strategies of presidents also have an important influence.
Modeling Earnings Dynamics

In this paper we use indirect inference to estimate a joint model of earnings, employment, job changes, wage rates, and work hours over a career. Our model incorporates duration dependence in several variables, multiple sources of unobserved heterogeneity, job-specific error components in both wages and hours, and measurement error. We use the model to address a number of important questions in labor economics, including the source of the experience profile of wages, the response of job changes to outside wage offers, and the effects of seniority on job changes. We provide estimates of the dynamic response of wage rates, hours, and earnings to various shocks and measure the relative contributions of the shocks to the variance of earnings in a given year and over a lifetime. We find that human capital accounts for most of the growth of earnings over a career although job seniority and job mobility also play significant roles. Unemployment shocks have a large impact on earnings in the short run as well a substantial long long-term effect that operates through the wage rate. Shocks associated with job changes and unemployment make a large contribution to the variance of career earnings and operate mostly through the job-specific error components in wages and hours.
Experimental feasibility assessment of MNP enhanced microwave diagnostics of breast cancer

A new technique, exploiting magnetic nanoparticles as contrast agent, has been recently proposed for microwave breast cancer imaging. As human tissues are non magnetic, the adoption of a magnetic contrast agent, able to selectively target tumoral cells, represents an effective means to increase diagnostic reliability. Although the effectiveness of the new technique has been fully assessed through realistic and accurate numerical simulations, an experimental proof-of-concept is still needed to set the ground for a subsequent pre-clinical stage. In this communication, we present the first results of such an experimental validation, performed with an ad hoc designed laboratory set-up and exploiting a realistic (although simplified) breast phantom.
Asset Securitization, Securitization Recourse, and Information Uncertainty

ABSTRACT: In this study, we examine some of the consequences of asset securitization. Specifically, using a sample of bank holding companies, we investigate whether the difficulty in assessing the true extent of risk transfer, between securitizing banks and investors in asset-backed securities, affects bank information uncertainty. We find that when market participants have a greater difficulty in estimating risk transfer, banks face greater information uncertainty (i.e., larger bid-ask spreads and analyst forecast dispersion). In addition, we find that this effect is mitigated for banks that operate in a higher quality information environment. We also find that banks that securitize financial assets have higher spreads and analyst forecast dispersion as compared to non-securitizing banks.
Novel Hepatitis B Virus Strain from a Chimpanzee of Central Africa (Pan troglodytes troglodytes) with an Unusual Antigenicity of the Core Protein

We and others have previously reported a hepatitis B virus (HBV)-like hepadnavirus strain which seemed to be indigenous to West African chimpanzees (Pan troglodytes verus). After that, we obtained an HBsAg-positive serum sample from a chimpanzee from Central Africa, named Bassi, belonging to another subspecies (P. troglodytes troglodytes). The full-genome nucleotide sequence of the hepadnavirus from Bassi showed a significant difference (9–26%) from those so far reported from primates including humans, chimpanzees and gorillas, suggesting a novel strain. More interestingly, however, the core antigen (HBcAg) deduced from Bassi’s sequence showed only 78–82% similarity to known primate strains at the amino acid level, whereas the other strains shared more than 90% similarity. HBcAg expressed from Bassi HBV failed to react with monoclonal antibodies that were directed at an epitope borne by codons 135–145 of HBcAg of conventional hepadnaviruses. This could explain why Bassi was negative for anti-HBc in a routine test. Here we report the novel HBV strain presumably indigenous to P. troglodytes troglodytes in Central Africa.
State and Output Feedback Control of Interval Type-2 Fuzzy Systems With Mismatched Membership Functions

This paper is concerned with the problems of state and output feedback control for interval type-2 (IT2) fuzzy systems with mismatched membership functions. The IT2 fuzzy model and the IT2 state and output feedback controllers do not share the same membership functions. A novel performance index, which is expressed as an extended dissipativity performance, is introduced to be a generalization of H∞, L2-L∞, passive, and dissipativity performances indexes. First, the IT2 Takagi-Sugeno fuzzy model and the controllers are constructed by considering the mismatched membership functions. Second, on the basis of Lyapunov stability theory, the IT2 fuzzy state and output feedback controllers are designed, respectively, to guarantee that the closed-loop system is asymptotically stable with extended dissipativity performance. The existence conditions of the two kinds of controllers are obtained in terms of convex optimization problems, which can be solved by standard software. Finally, simulation results are provided to illustrate the effectiveness of the proposed methods.
Fusing Social Media Cues: Personality Prediction from Twitter and Instagram

Incorporating users' personality traits has shown to be instrumental in many personalized retrieval and recommender systems. Analysis of users' digital traces has become an important resource for inferring personality traits. To date, the analysis of users' explicit and latent characteristics is typically restricted to a single social networking site (SNS). In this work, we propose a novel method that integrates text, image, and users' meta features from two different SNSs: Twitter and Instagram. Our preliminary results indicate that the joint analysis of users' simultaneous activities in two popular SNSs seems to lead to a consistent decrease of the prediction errors for each personality trait.
A Growing Demand for Monitoring and Evaluation in Africa

When decision-makers want to use evidence from monitoring and evaluation (M&E) systems to assist them in making choices, there is a demand for M&E. When there is great capacity to supply M&E information, but low capacity to demand quality evidence, there is a mismatch between supply and demand. In this context, as Picciotto (2009) observed, ‘monitoring masquerades as evaluation’. This article applies this observation, using six case studies of African M&E systems, by asking: What evidence is there that African governments are developing stronger endogenous demand for evidence generated from M&E systems? The argument presented here is that demand for evidence is increasing, leading to further development of M&E systems, with monitoring being dominant. As part of this dominance there are attempts to align monitoring systems to emerging local demand, whilst donor demands are still important in several countries. There is also evidence of increasing demand through government-led evaluation systems in South Africa, Uganda and Benin. One of the main issues that this article notes is that the M&E systems are not yet conceptualised within a reform effort to introduce a comprehensive results-based orientation to the public services of these countries. Results concepts are not yet consistently applied throughout the M&E systems in the case countries. In addition, the results-based notions that are applied appear to be generating perverse incentives that reinforce upward compliance and controle to the detriment of more developmental uses of M&E evidence.
Conductive polymer nanowire gas sensor fabricated by nanoscale soft lithography

Resistive devices composed of one-dimensional nanostructures are promising candidates for the next generation of gas sensors. However, the large-scale fabrication of nanowires is still challenging, which restricts the commercialization of such devices. Here, we report a highly efficient and facile approach to fabricating poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) nanowire chemiresistive gas sensors by nanoscale soft lithography. Well-defined sub-100 nm nanowires are fabricated on silicon substrate, which facilitates device integration. The nanowire chemiresistive gas sensor is demonstrated for NH3 and NO2 detection at room temperature and shows a limit of detection at ppb level, which is compatible with nanoscale PEDOT:PSS gas sensors fabricated with the conventional lithography technique. In comparison with PEDOT:PSS thin-film gas sensors, the nanowire gas sensor exhibits higher sensitivity and a much faster response to gas molecules.
Living large: Affect amplification in visual perception predicts emotional reactivity to events in daily life

It was hypothesised that affect-amplifying individuals would be more reactive to affective events in daily life. Affect amplification was quantified in terms of overestimating the font size of positive and negative, relative to neutral, words in a basic perception task. Subsequently, the same (N=70) individuals completed a daily diary protocol in which they reported on levels of daily stressors, provocations, and social support as well as six emotion-related outcomes for 14 consecutive days. Individual differences in affect amplification moderated reactivity to daily affective events in all such analyses. For example, daily stressor levels predicted cognitive failures at high, but not low, levels of affect amplification. Affect amplification, then, appears to have widespread utility in understanding individual differences in emotional reactivity.
The Intertemporal Elasticity of Substitution: An Exploration using a US Panel of State Data

This paper uses state-level consumption data to estimate the intertemporal elasticity of substitution of consumption (IES). In contrast to the results of Hall (1988) and Campbell and Mankiw (1989), we provide evidence indicating that the IES is significantly different from zero and probably close to one. Since inference about the IES in the context of the standard Euler equation is problematic as a result of mis-specification bias, we cast most of our discussion in the context of the framework developed by Campbell and Mankiw. This modifies the Euler equation in that a fraction of agents simply consume their income. The use of panel data to examine the relationship between interest rates and consumption growth has two advantages. First, we achieve a significant increase in precision, which in particular allows us to rule out a zero IES. Second, we can use the panel aspect of the data to bypass asset return measurement problems. In particular, we identify a common time component in expected consumption growth that is associated with movements in interest rates when the IES is positive.

Precautionary savings under income uncertainty: a cross-sectional analysis

The first part of this paper derives a closed fro solution for present consumption as a function of current and expected economic variables, which contains a precautionary component that is directly affected by future income risk. An estimating equation forthe structural relationship between savings and their determinants is discussed and tested using cross-sectional data from the 1984 UK Family Expenditure Survey.
Serum Albumin Is Superior to Prealbumin for Predicting Short-Term Recurrence in Patients with Operable Colorectal Cancer

The relationship between preoperative prealbumin and cancer survival has not been fully elucidated. The purpose of this study was to examine the relationship between preoperative nutritional conditions, including prealbumin and albumin concentrations, and the risk of recurrence in cases with operable colorectal carcinoma. One hundred fifty-eight patients who underwent elective colorectal resection were analyzed in this study. Of the eligible cases, 56 (35.4%) had decreased serum prealbumin and 15 (9.5%) had decreased serum albumin preoperatively. Among 158 cases in this study, 18 (11.4%) had disease recurrence. In the univariate analysis, the depth of tumor invasion, lymph node metastasis, lymphovascular invasion, serum albumin, prealbumin, and carcinoembryonic antigen were the factors significantly associated with disease recurrence. Multivariate analysis demonstrated that only serum albumin was a predictor of the recurrence; however, serum prealbumin lost its significance on multivariate analysis. Time to tumor recurrence by Kaplan-Meier curves significantly differed among patients with low serum albumin and prealbumin level. Our results suggest that prealbumin and albumin may be sensitive indicators of the risk of recurrent disease; however, low serum albumin levels are more useful than prealbumin in predicting short-term disease recurrence in operable colorectal cancer.
The effectiveness of training in public sector organisations: A case study of the College of the Arts in Windhoek, Namibia

This study focused on investigating the effectiveness of in-service training programs provided to lecturers at the College of the Arts. The objectives of the study were: to investigate the effectiveness of the in-service training programs at the College of the Arts for the upgrading of teaching skills and specialist subject knowledge of academic staff members and to identify how these in-service training programs can successfully be used to improve the performance of academic staff members at College of the Arts. The study adopted a mixed research approach of qualitative and quantitative methods, made used of a multiple case study design to collect data through interviews as well as conducting lesson observations. The study also employed a descriptive design, and used close ended questions to gather data through questionnaires. Content analysis method was used to analyse the qualitative data. Quantitative data were processed using the Statistical Package for the Social Sciences (SPSS) IBM version 21 software package and descriptive statistics was used to interpret the participants’ responses. The methodological triangulation of data was accomplished through the use of data obtained through the interviews, observations and questionnaires.
