The concept of smart mobility depends on a country’s or city’s visions and surroundings, such as traffic issues and available transportation modes. This study, therefore, proposes a clear and consistent set of definitions for smart mobility, in the context of past, present, and future, based on investigations of smart mobility practices in South Korea and overseas. In addition, smart mobility definitions are collected from various written sources and analyzed via text mining to define levels of smart mobility beyond the present service level. This study therefore defines smart mobility in six stages: level 0, base infrastructure; level 1, individual digitization; level 2, partial integration; level 3, full integration; level 4, personalized integration; and level 5, mobility transformation. The definition of each stage includes the scope of transportation modes to be integrated, required technology level, mobility operations, and user convenience. This definition of smart mobility by stage will be beneficial for setting the targeted levels of smart mobility services in projects and for setting goals not only in the present context but also for the future of smart mobility, which will be utilized as a roadmap for the implementation of smart mobility in many countries and cities.

The Impact

In this paper, the definition of seaport fairway capacity, considering port service level, is given by referring to both road and inland waterway capacity combined with the features of coastal fairways. In view of the navigation environment and ships' behaviour, the safety distance of ships entering and leaving a seaport is chosen as an overall index to evaluate the navigational safety level of a fairway. Based on the ship-following theory, an Arena-based seaport operating system simulation model is constructed to analyse the impact of safety level on seaport fairway capacity. For different navigational safety levels (i.e., minimum, general and adequate), seaport fairway capacity corresponding to different service levels and navigation durations is obtained. The results show that fairway capacity varies with safety level for a given port service level, and the lower the safety level is, the higher the fairway capacity is. Finally, a recommended navigational safety level and its associated fairway capacity are given to provide a theoretical foundation for fairway design and management.

This work aims to reorganize theoretical and empirical research on smart mobility through the systematic literature review approach. The research goal is to reach an extended and shared definition of smart mobility using the cluster analysis. The article provides a summary of the state of the art that can have broader impacts in determining new angles for approaching research. In particular, the results will be a reference for future quantitative developments for the authors who are working on the construction of a territorial measurement model of the smartness degree, helping them in identifying performance indicators consistent with the definition proposed.

Competitiveness can be defined in a number of ways. We can think of it as of a successful performance of a company or organization; or we may talk about competitiveness in a macro context such as a favourable exchange rate of a national currency. Can we also talk about competitiveness of a nation? What is it and how can it be evaluated?There does not seem to be a common definition of what the international competitiveness of nations is. Some feel that the very notion of international competitiveness of nations is unfair and unacceptable. They argue that the nations themselves do not compete, their enterprises do. For others the notion of international competitiveness of nations is fair. They believe that creating appropriate measures of international competitiveness is central for tracking and understanding the sources of competitiveness of countries.In this paper I classify and compare the measures developed by various authors. I suggest that the studies on the measurement of competitiveness can be classified into five groups:1. Particular sector studies.2. Competitiveness studies at the regional / country level.3. Particular competitiveness indicator studies.4. Competitiveness studies at an international level.5. Cross-country economic policy studies.Since the competitiveness studies serve a different audience and purpose, we cannot discuss which is best without first asking: best at what?

The article is devoted to the theoretical and legal analysis of issues related to the range of problems connected with development of such legal model as ‘nonentrepreneurial legal entity’. In the scientific work the author makes an analysis of those concepts which are submitted by the leading Ukrainian scholars and concern the formation of civil-law terminology in general and that is applied to the nonentrepreneurial legal entities, in particular. The author has concluded that it is expedient to apply the set of criteria during formation of the non-entrepreneurial legal entity. The article gives the definition of non-entrepreneurial legal entity in the narrow and broad meanings. It is proved that a non-business entity should be singled out as a separate category according to the non-distribution of profit (income) rather than to the specifics of its business activity. The author demonstrates the feasibility to change classification criteria and levels while classifying the legal entities and on the mentioned ground she has singled out: 1) procedure for establishment of the legal entity; 2) structure of the legal entity as a criterion of the second classification level; 3) specific character of the profit distribution as a criterion of the third level of classification. It is based on the argument that non-business entities are an independent group of the legal entities, which is divided into subgroups: the non-business entities of corporate type and the non-business entities of unitary type. Each subgroup of the non-business legal entity distinguishes several legal forms within of which specific types of non-business entities are allocated. The author presents one’s own definition of the non-entrepreneurial legal entity, as a legal entity of public or private law, whether of corporate or unitary type, which is specially established in the different areas of social life and endowed with a special legal capacity. The non-entrepreneurial legal entity shall be entitled to carry out activities with a view to profit but it doesn’t distribute it among participants (members).

Despite advanced supply chain planning and execution systems, manufacturers and distributors tend to observe service levels below their targets, owing to different sources of uncertainty and risks. These risks, such as drastic changes in demand, machine failures, or systems not properly configured, can lead to planning or execution issues in the supply chain. It is too expensive to have planners continually track all situations at a granular level to ensure that no deviations or configuration problems occur. We present a machine learning system that predicts service-level failures a few weeks in advance and alerts the planners. The system includes a user interface that explains the alerts and helps to identify failure fixes. We conducted this research in cooperation with Michelin. Through experiments carried out over the course of four phases, we confirmed that machine learning can help predict service-level failures. In our last experiment, planners were able to use these predictions to make adjustments on tires for which failures were predicted, resulting in an improvement in the service level of 10 percentage points. Additionally, the system enabled planners to identify recurrent issues in their supply chain, such as safety-stock computation problems, impacting the overall supply chain efficiency. The proposed system showcases the importance of reducing the silos in supply chain management.

Data in the Cloud, which applies to data as a cloud service provider (CSP), transmits stores, or manages it. The company will enforce the same definition of data usage while the data is resident within the enterprise and thus extend the required cryptographic security criteria to data collected, exchanged, or handled by CSP. The CSP Service Level Agreements cannot override the cryptographic access measures. When the data is transferred securely to CSP, it can be securely collected, distributed, and interpreted. Data at the rest position applies to data as it is processed internally in organized and in the unstructured ways like databases and file cabinets. The Data at the Rest example includes the use of cryptography for preserving the integrity of valuable data when processed. For cloud services, computing takes multiple forms from recording units, repositories, and many unstructured items. This paper presents a secure model for Data at rest. The TF-Sec model suggested is planned for use with Slicing, Tokenization, and Encryption. The model encrypts the given cloud data using AES 256 encryption, and then the encrypted block is sliced into the chunks of data fragments using HD-Slicer. Then it applies tokenization algorithm TKNZ to each chunk of data, applies erasure coding technique to tokens, applies the data dispersion technique to scramble encrypted data fragments, and allocates to storage nodes of the multiple CSP. In taking the above steps, this study aims to resolve the cloud security problems found and to guarantee the confidentiality of their data to cloud users due to encryption of data fragments would be of little benefit to a CSP.

Abstract Motivation SBML is the most widespread language for the definition of biochemical models. Although dozens of SBML simulators are available, there is a general lack of support to the integration of SBML models within open-standard general-purpose simulation ecosystems. This hinders co-simulation and integration of SBML models within larger model networks, in order to, e.g. enable in silico clinical trials of drugs, pharmacological protocols, or engineering artefacts such as biomedical devices against Virtual Physiological Human models. Modelica is one of the most popular existing open-standard general-purpose simulation languages, supported by many simulators. Modelica models are especially suited for the definition of complex networks of heterogeneous models from virtually all application domains. Models written in Modelica (and in 100+ other languages) can be readily exported into black-box Functional Mock-Up Units (FMUs), and seamlessly co-simulated and integrated into larger model networks within open-standard language-independent simulation ecosystems. Results In order to enable SBML model integration within heterogeneous model networks, we present SBML2Modelica, a software system translating SBML models into well-structured, user-intelligible, easily modifiable Modelica models. SBML2Modelica is SBML Level 3 Version 2—compliant and succeeds on 96.47% of the SBML Test Suite Core (with a few rare, intricate and easily avoidable combinations of constructs unsupported and cleanly signalled to the user). Our experimental campaign on 613 models from the BioModels database (with up to 5438 variables) shows that the major open-source (general-purpose) Modelica and FMU simulators achieve performance comparable to state-of-the-art specialized SBML simulators. Availability and implementation SBML2Modelica is written in Java and is freely available for non-commercial use at https://bitbucket.org/mclab/sbml2modelica.

PurposeThis paper explores the effect of port's service time, particularly the mean and variability, on shippers' total landed costs to determine the competitive position of the port and derive recommendations for the strategic design of port services.Design/methodology/approachThe competitive position of a port is estimated considering the service level offered to the end-users of the port such as port service time, its variability and its effect on the total landed costs observed by the port users. The proposed methodology is meant to help ports to determine the required service time levels to maintain or gain a competitive advantage against other ports, in terms of attracting common hinterland's customers.FindingsResults show the advantages of considering service levels factors to determine the competitive position of a port, and what are the minimum characteristics required to capture more traffic volumes, that can help port managers to take strategic design decisions to better position the port in the current fierce market.Research limitations/implicationsThe proposed methodology is illustrated by considering a case study, which is the Port of Guaymas in Mexico. Data was not directly collected by the port, but based on interviews with shippers and public information, a representative case is presented. Due to a confidentiality agreement with the Port, specific references for most of the data used to estimate the model's parameters are not provided. The analysis is intended to show the potential value of this mechanism and can be used for evaluating the competitive position, from a high-level perspective, of any port to determine potential hinterland by improving the service level of the port.Originality/valueThe existing literature on port choice and port competition has not previously considered the effect of port service levels under the perspective of total landed costs of the users, being this paper a contribution to fulfill this gap.

Bill of Services (BOS) is a novel management tool designed to support service organizations in developing their services and planning resources to satisfy management's target service level. This paper presents a methodology for configuration of the BOS in a manner similar to configuration of the Bill of Materials (BOM) in a manufacturing organization. Definition of the BOS enables management to calculate the capacity of the resources needed to satisfy service demand and support the cost process of any service category in the organization. The BOS may also support management during the phase of negotiations with potential customers by testing various service alternatives. The BOS assists management in the day-to-day planning and control of activities, and facilitates a professional management infrastructure in service organizations. The paper presents a detailed example of a hotel BOS and elaborates the advantages of using this management tool.

National Association Of Evangelicals

Much of the best recent scholarship on conservative Protestantism in the middle decades of this Century focuses on what is sometimes called the “mainstream” of interdenominational evangelicalism. Although this variety of evangelicalism was deeply influenced by and, indeed, in some respects the direct successor to the fundamentalist movement of the 1910's, 1920's, and 1930's, it did not begin to assume its present shape until the early 1940's. The formation of the National Association of Evangelicals in 1942 is a convenient symbol of the emergence of what we now think of as constituting the evangelical mainstream.Drafting a perfect definition of this mainstream is impossible; drafting a good working description of it is not. In the present context, “evangelical mainstream” simply refers to that network of born-again Christians associated with the Billy Graham Evangelistic Association, the National Association of Evangelicals, and Campus Crusade for Christ; with schools such as the Moody Bible Institute, Füller Seminary, and Wheaton College; with publishing firms like Eerdman's and Zondervan; and with magazines such as Christianity Today, Eternity, and Moody Monthly.
