To improve the satisfaction of both service demanders (SDs) and service providers (SPs) in the matching of cloud manufacturing (CMfg) tasks and services, a two-sided stable matching model of CMfg tasks and service considering the nonlinear relationship between satisfaction and expectations is proposed. As the expectations of SDs and SPs are difficult to be quantified directly, an evaluation method based on interval-valued hesitant fuzzy linguistic sets (IVHFLSs) is first presented. Next, a nonlinear model of satisfaction and expectations is built to quantify the satisfaction, which achieves accurate quantification of satisfaction. Then, a two-sided stable matching model of CMfg tasks and service is built, which takes the satisfaction of SDs and SPs as the optimization goals and considers the individual rationalities and blocking pairs. Finally, an adaptive genetic algorithm (AGA) is designed to solve the proposed two-sided matching model. A practical application and comparison analysis is used to verify the effectiveness and superiority of the research.

Abstract To account for the effects of multiple impairments, evaluating physicians must provide a summary value that combines multiple impairments so the whole person impairment is equal to or less than the sum of all the individual impairment values. A common error is to add values that should be combined and typically results in an inflated rating. The Combined Values Chart in the AMA Guides to the Evaluation of Permanent Impairment, Fifth Edition, includes instructions that guide physicians about combining impairment ratings. For example, impairment values within a region generally are combined and converted to a whole person permanent impairment before combination with the results from other regions (exceptions include certain impairments of the spine and extremities). When they combine three or more values, physicians should select and combine the two lowest values; this value is combined with the third value to yield the total value. Upper extremity impairment ratings are combined based on the principle that a second and each succeeding impairment applies not to the whole unit (eg, whole finger) but only to the part that remains (eg, proximal phalanx). Physicians who combine lower extremity impairments usually use only one evaluation method, but, if more than one method is used, the physician should use the Combined Values Chart.

Background: Currently, Cloud Service Provider (CSP) or third party usually proposes principles and methods for cloud security risk evaluation, while cloud users have no choice but accept them. However, since cloud users and cloud service providers have conflicts of interests, cloud users may not trust the results of security evaluation performed by the CSP. Also, different cloud users may have different security risk preferences, which makes it difficult for third party to consider all users' needs during evaluation. In addition, current security evaluation indexes for cloud are too impractical to test (e.g., indexes like interoperability, transparency, portability are not easy to be evaluated). Methods: To solve the above problems, this paper proposes a practical cloud security risk evaluation method of decision-making based on conflicting roles by using the Analytic Hierarchy Process (AHP) with Aggregation of Individual priorities (AIP). Results: Not only can our method bring forward a new index system based on risk source for cloud security and corresponding practical testing methods, but also can obtain the evaluation result with the risk preferences of conflicting roles, namely CSP and cloud users, which can lay a foundation for improving mutual trusts between the CSP and cloud users. The experiments show that the method can effectively assess the security risk of cloud platforms and in the case where the number of clouds increased by 100% and 200%, the evaluation time using our methodology increased by only by 12% and 30%. Conclusion: Our method can achieve consistent decision based on conflicting roles, high scalability and practicability for cloud security risk evaluation.

Informal settlements represent a challenging operational context for local government service providers due to precarious contextual conditions. Location choice and land procurement for public infrastructure raise the complicated question: who has the right to occupy, control, and use a piece of land in informal settlements? There is currently a dearth of intelligence on how to identify well-located land for public infrastructure, spatially and with careful consideration for safeguarding the claimed rights and preventing conflicts. Drawing on a case study of green infrastructure retrofit in seven informal settlements in Makassar, Indonesia, we classify the informal settlers’ land rights into four types: ownership, use, control, and management. This exploratory study uses a typological approach to investigate the spatial dimension of land rights in informal settlements. We introduce non-registrable land interests and the partial, dynamic, and informal land use rights that impact the land procurement for infrastructure retrofit. We also create a simple spatial matrix describing the control/power, responsibilities and land interests of different stakeholders involved in the location decision making for public infrastructure. We argue that without sufficient understanding of non-formal land rights, land procurement proposals for the public infrastructure upgrades can be frustrated by the individual or group claims on the land, making the service provision impossible in informal settlements.

The NDIS introduces changes to the level of control, choice and flexibility that persons with a disability can exercise over the services they require to support their individual needs. One of the main stays of NDIS is the ability for persons with a disability to utilise allocated funding how and with whom they choose to create a package of supports. Coinciding with the move towards the NDIS has been the introduction of the NSW WHS Act 2011. This Act introduces and broader new definitions relating to persons with responsibilities for ensuring health and safety at work. In some circumstances the individual person with a disability will be a direct employer, or an “other” in the workplace, and will take on responsibilities for health and safety for persons working in their home. For government organisations making funding decisions and allocating funds for the purchase of support services, there continues to be an obligation to ensure that services are conducted safely with risks to health adequately managed. NSW FACS can not “contract” out of their obligations. Instead we must work in partnership with all stakeholders to manage WHS risks as far as is reasonably practicable. Our role in government means we have the resources, experience, and must respond to the community expectation that we will support persons with a disability to understand and discharge their WHS obligations as far as is reasonably practicable. This is a way of operating presents the following questions: Do persons with disability understand the WHS obligations and risks associated with their care and supports? How to individuals with disability obtain sound advice and information on WHS risks that may be associated with their care arrangements? Can WHS information and resources that organisations like NSW Department of Family and Community Services (Ageing Disability and Home Care) have established be leverages to share with our “clients”? As Government partners in NDIS are we obligated to share our knowledge and information? What is the best way to bridge the gap in understanding and what types of information, tools and training can be made available on WHS for persons with a disability.A Joint WHS project currently underway within NSW FACS seeks to address the information and resources gap for all clients who participate in self directed funding arrangements (including NDIS). Our project will demonstrate how products and advice developed for internal staff use can be “reframed” and made accessible to persons with disability, their carers and individual service providers. The approach being applied within NSW FACS will potentially reduce costs in persons with disability being required to engage additional services to seek and develop WHS direct guidance and tools. The project being undertaken will deliver face to face training models, e-learning components and online information and tools to assist stakeholders in the NDIS and other Direct Funding Arrangements within NSW, to make informed decisions regarding WHS risk in the provision of care and support services. Guidance and information is provided on key risk areas utilising tested tools & WHS resources within the disability sector. E-learning solutions are made available to inform and train stakeholders of WHS obligations and potential risk management approaches. NSW FACS works with NGO stakeholders to ensure consistent advice and assistance is provided in the area of WHS obligations and performance expectations.

Purpose This study aims to address the paradigm changes currently affecting tourism: the increasingly recognisable signs of irreversible climate change and the consequences of this and overtourism for service providers, destinations and tourists’ experiences. A more specific objective was to identify good practices carried out by destinations and companies in different tourism sectors to increase sustainability. Design/methodology/approach The research involved examining the academic, institutional and trade literature to develop an overview of the most important challenges and an accurate portrayal of how innovative and proactive companies and destination managers are addressing these issues. Findings Increased tourism demand has contributed to social and environmental unsustainability in tourism. Although the tourism sector has already implemented sustainable initiatives, an accurate quantification and measurement of these practices’ real impacts on global tourism’s sustainability is not yet possible. Originality/value This study’s value arises from the systematic identification of the implications of climate change and overtourism as major features of a paradigm shift in tourism. This paper also presents a set of good practices to provide tourism stakeholders with more sustainable strategies and inspire these entities to adopt appropriate measures.

It’s important to control telecom equipment maintenance outsourcers’ performance in outsourcing decision-making process by selecting the proper evaluation indexes. This paper sets up a new comprehensive evaluation method based on statistics distance with weight to assess outsourcer’s performance. Ten indexes are choosed to determine which are good service providers from the ability and effort degree of their work, including failure rate, failure loss, service level, maintenance price, management fee, arrive time, repair time, customer relationship, maintenance engineer and tool machine. Each index has its own expert’s weight. We classify different service grades and calculate the real distance of every maintenance outsourcer by Euclidean distance. Then the performance of each equipment maintenance outsourcer can be inspected from the calculation result. Through the application in telecom company we testify its advantages compared with other evaluation methods.

AbstractUser involvement has become an explicit goal within social service provision. Even so, the term remains ambiguous, and its implementation troublesome. Implementation theory lists a number of factors influencing bureaucratic behaviour; in this paper we investigate the ‘human factor’. Our ambition is to provide a framework for analysis of user influence in activation programmes that includes the individual characteristics of both service users and service providers. Building on theoretical insights from the literature on activation and agency, we develop a framework that distinguishes between two ideal types of service users: Pawns and Queens, and two types of service providers: care-oriented Carers and rule-oriented Clerks. This framework is then applied to identify key challenges for the interaction between users and caseworkers in two challenging situations: when service users express little or no agency and when they express agency that is incompatible with the overall goals of the programme. We find that Carers show pronounced reluctance to overrule the choices made by service users even when they have conflicting views – and tend to postpone decisions when they interact with Pawns. Clerks tend to overrule the decisions of Queens when they have conflicting views, and to make decisions on behalf of Pawns. The analysis draws on data collected from 126 qualitative interviews with service providers and participants in the Norwegian Introductory Programme for immigrants and a survey of 320 caseworkers.

Among the wide range of cloud service providers with different performance characteristics, in order to let the cloud users find cloud services which satisfy its performance preferences and specific trust levels,it needs to establish a reasonable and scientific cloud service trust evaluation system. This paper introduces a membership degree theory into trust evaluation model. First, it designs the trust evaluation system framework of cloud services, and establishes a trust evaluation model of cloud services. Next, it calculates the trust level of cloud services with the comprehensive trust cloud center of gravity evaluation method (CCGE). Finally, the experiment results show that this model can build precise trust relationship between cloud users and cloud services based on users performance demands.
