Abstract:

Monitoring microbial water quality is essential for recreational beaches in order to protect human health. To evaluate the relative importance and impacts of various types of non-point microbial sources at a subtropical beach (Hobie Beach, Miami, USA), we utilized a coastal ocean circulation model (Delft3D) with a microbe transport-fate model. Those non-point sources include beach sediment, dog feces, bather shedding, and rainfall runoff. The hydrodynamic model results agreed well with tidal elevations recorded by a nearby NOAA tidal station and also field data collected by pressure sensors, acoustic Doppler current profiler (ADCP). We modeled enterococci levels from four different types of non-point sources on the beach and Staphylococcus aureus levels from only the bather shedding. Model results suggest that dog feces are spotty sources of enterococci and can result in transient spikes of enterococci levels for hours. Beach sands are pervasive sources of enterococci and may explain observed persistent elevations of enterococci levels at this site. Runoff may also significantly increase enterococci levels during rainfall events while bather shedding contribution of enterococci is almost negligible. Bather is the only Staphylococcus aureus source considered in the study and simulated levels are in the same order as prior field measurements.

Abstract:

AbstractFirm operators continually manage multiple sources of risk. In an application to cattle feedlot operations, our objective is to determine if producers view output price and animal health risks separately or jointly. We conduct a survey with a choice experiment placing operators in forward looking, decision-making scenarios, and capture information on past risk management approaches. Evidence regarding a relationship between animal health and output price risk mitigation is mixed and depends on the decision being made. Combined, these results provide new insight into how managers approach multiple risks when facing resource constraints.

Abstract:

To complement the current studies of risk assessment on water sources which seldom consider the distribution effects of multiple risk sources concentration, and improve the efficiency of water source supervision, this study establishes a method system for risk assessment of water sources and regulatory rating evaluation under the distribution effects of multiple risk sources concentration. The method system includes: (1) utilizing the single-risk source impact index to characterize the risk impact degree of the single-risk source on the water source, the index calculation method of single-risk source impact considers the risk degree and the distribution location of risk source; (2) using the multiple risk sources impact index to characterize the risk impact degree of the multiple risk sources on the water source, the index calculation method of multiple risk sources considers the impact index of single-risk source, the number of risk sources, and the distribution concentration of multiple risk sources; (3) the environmental risk assessment and regulatory rating evaluation method consider multiple risk sources impact index, anti-risk ability of water source, and the importance of water source. This method system has been applied to the environmental risk assessment and regulatory rating of eight water sources along the Nanjing Yangtze River, with excellent achievements. As the results reveal, eight water sources suffer 437 risk impacts from 175 risk sources, 69.04% of which are low-risk impacts and 13 are high-risk impacts. Longtan water source suffers the most risk impacts of 86, among which eight are high-risk impacts. The impacts of multiply-risk sources on the eight water sources are high-risk impacts. The impact index of multiple risk sources increases from the upstream water sources to the downstream water sources, reaching the maximum value of 5.267 at the most downstream Longtan water source. Though the environmental risk and supervision rating of Longtan water source is high, those of other water sources are rated as medium.

Abstract:

Stabilized N sources are N fertilizers treated with urease inhibitors, nitrification inhibitors, or a combination of both. They can comprise “right source” in many situations in which 4R Nutrient Stewardship is implemented. Several meta-analyses demonstrate that nitrification inhibitors with and without urease inhibitors consistently reduce N2O emissions. Nitrification inhibitors are effective at decreasing NO3- leaching but can increase ammonia volatilization, while urease inhibitors are effective at preventing volatilization losses.

Abstract:

As the informationization of the medicare sector in China grows up and the sources of the rehabilitation data are distributed and multi-leveled from different centers, it is urgently needed to integrate the resources of various application systems, implement unified data exchange of the distributed and heterogeneous multiple data sources and encapsulate the data resources into various kinds of services. For this purpose, this paper puts forward the idea of SOA-based cloud services encapsulation and integrated architecture. At first, the multi-source and heterogeneity of data and the integration of information in the rehabilitation management are analyzed. Then, the cloud services encapsulation and integration technology is study to find out how to encapsulate data resources into various kinds of services, build a SOA-based cloud services platform, find a solution for the integration of multi-sourced and heterogeneous data, and meet the function extension, encapsulation and release of cloud services arising out of changing demands. At last, A case of the cloud platform system is presented to show the feasibility and effectiveness of the architecture platform.

Abstract:

The aim of this article is to review the literature on the topic of sustained and temporary competitive advantage creation, specifically in dynamic markets, and to propose further research possibilities. After having analyzed the main trends and scholars’ works on the subject, it was concluded that a firm which has been experiencing erosion of its core sources of economic rent generation, should have diversified its strategy portfolio in a search for new sources of competitive advantage, ones that could compensate for the decline of profits provoked by intensive competitive environments. This review concludes with the hypothesis that firms, who have decided to enter and manage multiple competitive environments, should have developed a multiple strategies framework approach. The management of this source of competitive advantage portfolio should have allowed persistence of a firm’s superior economic performance through the management of diverse temporary advantages lifecycle and through a resilient effect, where a very successful source of competitive advantage compensates the ones that have been eroded. Additionally, the review indicates that economies of emerging countries, such as the ones from the BRIC block, should present a more complex competitive environment due to their historical nature of cultural diversity, social contrasts and frequent economic disruption, and also because of recent institutional normalization that has turned the market into hypercompetition. Consequently, the study of complex competition should be appropriate in such environments.

Abstract:

Purpose – The purpose of this paper is to examine the moderating role of passive leadership in the relationships of perceived support from organization, coworkers, and physicians to affective commitment and organizational citizenship behavior (OCB) among hospital employees. Design/methodology/approach – Using a sample of 182 hospital employees and a time-lagged design in which predictors and moderator were assessed at Time 1 and self-reported OCB was obtained 2.5 years later, the authors examined whether passive leadership moderates the relationships of perceived supports to commitment and their indirect effects on OCB. Findings – Analyses indicate that at high levels of passive leadership, the relationship between support from organization and coworkers and commitment is less positive and the relationship between support from physicians and commitment is negative. Moreover, the indirect effect of perceived support from coworkers and physicians on OCB through affective commitment is weaker at high levels of passive leadership. Research limitations/implications – Although the data used were self-reported, the analyses show that method variance accounted for only 9 percent of the variance among constructs at Time 1. Findings contribute to highlight the boundary conditions associated with perceived support and establish that passive leadership severely limits the beneficial effects expected from support available to employees. Practical implications – Findings suggest that supervisors should be trained not only on improving positive leadership skills but also on reducing passive behaviors in the face of problems in their teams. Originality/value – This study extends the understanding of social exchange processes in organizations and invites managers and researchers to look at factors that slow down the development of social exchange relationships with employees.

Full text

Abstract:

This work focuses on energy management for a system operated by multiple energy sources which include batteries, super capacitors, a hydrogen fuel cell, and a photovoltaic cell. The overall objective is to minimize the power consumption from all sources needed to satisfy the system’s power demand by optimizing the switching between the different energy sources. A dynamic mathematical model representing the energy sources is developed taking into account the different constraints on the system, i.e., primarily the state-of-charge of the battery and the super capacitors. In addition to the model, a heuristic approach is developed and compared with the mathematical model. Both approaches were tested on a multi-energy source ground robot as a prototype. The novelty of this work is that the scheduling of an energy system consisting of four different types of sources is compared by performing analysis via dynamic programming, and a heuristic approach. The results generated using both methods are analyzed and compared to a standard mode of operation. The comparison validated that the proposed approaches minimize the average power consumption across all sources. The dynamic modeling approach performs well in terms of optimization and provided a superior switching sequence, while the heuristic approach offers the definite advantages in terms of ease of implementation and simple computation requirements. Additionally, the switching sequence provided by the dynamic approach was able to meet the power demand for all simulations performed and showed that the average power consumption across all sources is minimized.

Abstract:

The continuous growth of available resources on the web, both in the form of Linked Open Data and on Social Networks, provides an important opportunity to gather information concerning specific kinds of touristic activities like, for example, cultural tourism, eco-tourism, bike-tourism, and so on. Both decision makers and tourists can take advantage from these data, as demonstrated by previous works, with institutional actors foreseeing an increase in the use of this data to substitute other time-consuming and expensive approaches. However, managing multiple sources built with different goals and structures is not straightforward, so specific design choices must be made when assembling this kind of information. Graph databases represent an ideal way to combine multiple-source data but, to be successful, strategies accounting for inconsistencies and format differences have to be defined to support coherent analysis. Also, the continuously changing nature of crowd-sourced data makes it difficult, for the research community, to compare technological approaches to the different tasks that are linked to cultural heritage, from recommendation to management. To support the research effort in this direction, we describe the data ingestion and enrichment procedure we followed to organise knowledge coming from three different sources, namely Wikidata, Wikipedia, and Flickr, into a single, application-oriented, resource organised as a graph database. We present the potential use of this resource to perform multiple source analyses targeting the specific case of cultural tourism on a nationwide scale, and we propose its use as a shared benchmark for technological applications designed to support optimal management of cultural resources.

Abstract:

The aim of this study was to elucidate the experience of self-management among people with multiple sclerosis (MS) and gather their input to inform a self-management intervention. Twelve people with MS participated in focus groups in which they were asked open-ended questions about MS symptoms, challenges, overcoming challenges, symptom management, and treatment preferences. The results suggest four major themes: 1) “The Everyday Experience of MS,” including comments about symptoms and their impact on functioning; 2) “Motivation for Self-Management,” including descriptions of motivation originating from physical necessity, success with other management techniques, and external sources; 3) “Coping Strategies and Skills,” including descriptions of changing behaviors, expanding social support networks, finding resources, utilizing medical treatment, and monitoring symptoms; and 4) “Vision for a Self-Management Intervention,” including suggestions that an intervention be individualized, be motivating, and provide resources. The results of this study can inform the design and implementation of self-management interventions. Experiences described by participants are consistent with other qualitative reports suggesting the active role people with MS play in managing their condition. Intervention approaches must consider the complex constellation of symptoms associated with MS and provide individualized treatments that enhance the person's ability to manage their symptoms, barriers presented by such symptoms, and their health care.

Abstract:

Consider a queueing system where the input traffic consists of background traffic, modeled by a Markov Arrival Process, and foreground traffic modeled by N ≥ 1 homogeneous on–off sources. The queueing system has an increasing and concave service rate, which includes as a particular case multiserver queueing systems. Both the infinite-capacity and the finite-capacity buffer cases are analyzed. We show that the queue length in the infinite-capacity buffer system (respectively, the number of losses in the finite-capacity buffer system) is larger in the increasing convex order sense (respectively, the strong stochastic order sense) than the queue length (respectively, the number of losses) of the queueing system with the same background traffic and M N homogeneous on–off sources of the same total intensity as the foreground traffic, where M is an arbitrary integer. As a consequence, the queue length and the loss with a foreground traffic of multiple homogeneous on–off sources is upper bounded by that with a single on–off source and lower bounded by a Poisson source, where the bounds are obtained in the increasing convex order (respectively, the strong stochastic order). We also compare N ≥ 1 homogeneous arbitrary two-state Markov Modulated Poisson Process sources. We prove the monotonicity of the queue length in the transition rates and its convexity in the arrival rates. Standard techniques could not be used due to the different state spaces that we compare. We propose a new approach for the stochastic comparison of queues using dynamic programming which involves initially stationary arrival processes.

Abstract:

A widespread methodological concern in the organizational literature is the possibility that observed results are due to the influence of common-method variance or mono-method bias. This concern is based on a conception of method variance as being produced by the nature of the method itself, and therefore, variables assessed with the same method would share common-method variance that inflates observed correlations. In this paper, we argue for a more complex view of method variance that consists of multiple sources that affect each measured variable in a potentially unique way. Shared sources among measures (common-method variance) act to inflate correlations, whereas unshared sources (uncommon-method variance) act to attenuate correlations. Two empirical examples, one from a simulation study and the other from a single-source survey, are presented to illustrate the complex action of multiple sources of method variance. A five-step approach is suggested whereby a theory of the measure is generated for each measured variable that would inform strategies to control for method variance by assessing and modeling the actions of identified method variance sources.

Abstract:

Understanding biological responses to nutrient enrichment under different environmental conditions is integral for the effective management of eutrophication in coastal environments. However, current conceptual models of nutrient enrichment are limited as they are based on studies that only consider a single source of nutrients, when in reality it is more likely that enrichment is a result of multiple sources. Here, we test the hypothesis that biological responses to nutrient enrichment in intertidal mudflat assemblages depend on the source by comparing enrichment from a controlled release fertilizer with that from decomposing macroalgae. Sediment at two sites in Port Phillip Bay, Victoria, were dosed with the different nutrient sources and monitored through time. After six weeks, the macroalgae-enriched plots had significantly higher abundances and biomass of some taxa of deposit-feeding polychaetes. In the fertilizer-enriched plots, the porewater nutrients increased but there was no detectable change in abundances or biomass of infauna, suggesting that the nutrients did not assimilate into the foodweb. The rate of assimilation of anthropogenic nutrients potentially occurs over longer time scales compared with the rapid assimilation and biological responses to decomposing macroalgae. Responses to the different nutrient sources provide new insights into the complexity of nutrient enrichment models that are applied to the management of aquatic ecosystems worldwide.

Abstract:

Abstract. Information about the spatial distribution of flood risk is important for integrated urban flood risk management. Focusing on urban areas, spatial flood risk assessment must reflect all risk information derived from multiple flood sources: rivers, drainage, coastal flooding etc. that may affect the area. However, conventional flood risk assessment deals with each flood source independently, which leads to an underestimation of flood risk in the floodplain. Even in floodplains that have no risk from coastal flooding, flooding from river channels and inundation caused by insufficient drainage capacity should be considered simultaneously. For integrated flood risk management, it is necessary to establish a methodology to estimate flood risk distribution across a floodplain. In this paper, a rainfall design method for spatial flood risk assessment, which considers the joint effects of multiple flood sources, is proposed. The concept of critical rainfall duration determined by the concentration time of flooding is introduced to connect response characteristics of different flood sources with rainfall. A copula method is then adopted to capture the correlation of rainfall amount with different critical rainfall durations. Rainfall events are designed taking advantage of the copula structure of correlation and marginal distribution of rainfall amounts within different critical rainfall durations. A case study in the Otsu River Basin, Osaka prefecture, Japan was conducted to demonstrate this methodology.

Abstract:

In this essay, we explore and discuss current practices of source critique. In our empirical analysis of a sample of interview-based studies, we find that few studies show a careful and reflective stance toward their sources. In the majority of cases, we discern a tendency to either ignore basic issues of the trustworthiness of interview material or produce technical descriptions which seem to have no real effect on the actual assessment of the study’s sources. We suggest five epistemic attitudes which describe how scholars engage—or rather not engage—in source critique. To improve source critique, we suggest tactics of intra- and extrasource critique which seriously consider interactional dynamics behind and quality of interview content other than “truth” reporting, aiming to corroborate interview statements by carefully cross-checking interview material with observations and multiple sources.

Abstract:

Many pollution-related issues are raising due to the usage of conventional internal combustion engines (ICEs) vehicles. Electric Vehicles/ Hybrid electric vehicles (EVs/HEVs) are the finest solutions to overcome those problems associated with ICE-based vehicles. The EVs are introduced with a signal energy source (SES), which is not a successful attempt, especially during transient vehicles, driving, etc. Multiple energy sources (MES) EVs are introduced to attain better performance than the SES vehicles, which is obtained by combining two sources like battery/fuel cells, ultracapacitor. In this contest, energy management (EMNG) plays a vital role in sharing the load to the sources as per the EVs requirement. In the case of MES-based EVs, the controller always plays a significant role in the related EMNG system because it is the key factor in improving vehicle efficiency. In this article, a study has mainly been done related to several conventional, intelligent controllers and control algorithms to do the proper EMNG between sources present in the EV.

Abstract:

Regional Sediment Management (RSM) is a planning approach that seeks to address coastal sediment processes on a broader geographic scale. It recognizes that sand, cobble, and fine sediment are important natural resources that are critical to the environmental health and economic vitality of the coastal zone. The relevant sediment processes overlap multiple geopolitical boundaries which explains why a regional planning perspective is needed. To be effective a comprehensive road map is needed to addresses how to conserve and restore the valuable sediment resources, reduce shoreline erosion and coastal storm damages, protect sensitive environmental resources, increase natural sediment supply to the coast, preserve and enhance beaches, improve water quality along the shoreline, and optimize the beneficial use of material dredged from ports, harbors, and other opportunistic sediment sources. The plan that was prepared for the diverse 144-mile long Santa Barbara and Ventura Counties coastline was developed systematically using traditional planning processes to understand the baseline science and relevant physical processes; identify the challenges that currently exist and the corresponding opportunities that can be seized to positively move forward; and formulate appropriate action plans and solutions that have unanimity of purpose. It is demonstrated that in order to be technically, environmentally, economically, and politically effective regional sediment management plans should consist of a suite of diverse study, management, policy, and capital project activities.
