Analysing Space-Time Accessibility Towards the Implementation of the Light Rail System: The Case Study of Brescia

This paper proposes a methodology for investigation of the space–time relations of accessibility to public services and collective mobility. The paper assesses the space–time efficiency of local public transport facilities and makes an accessibility analysis as a baseline for evaluating future changes. It explains the potential for improvement and the effects on planning paradigms. Public transport accessibility greatly changes during day and night time so they should be assessed through multi-scaled and diachronic maps as a contribution to the timetable plan and overall planning strategies. The case study of Brescia, Italy is used to test the methodology. The new light rail system of Brescia entered into operation in 2013 and could change the entire form of urban mobility.     

Utilizing job resources: Qualitative evidence of the roles of job control and social support in problem solving

Abstract

In resource-based models of job design, job resources, such as control and social support, are thought to help workers to solve problems. Few studies have examined this assumption. We analyzed 80 qualitative diary entries (N=29) and interviews (N=37) concerned with the in-role requirements of medical technology designers in the UK for problem solving. Four themes linked to using the resources of job control and social support for problem solving emerged. These were: (1) eliciting social support to solve problems; (2) exercising job control to solve problems; (3) co-dependence between eliciting social support and exercising job control to solve problems; and (4) using job resources to regulate affect. The results were largely supportive of the assumptions underpinning resource-based models of job design. They also indicated that the explanatory power of resource-based models of job design may be enhanced by considering interdependencies between various factors: how different job resources are used, workers' motivation to use resources, workers' knowledge of how to use resources and the use of resources from across organizational boundaries. The study provides qualitative support for the assumption that social support and job control are used to cope with demands.     

An ant colony algorithm for solving budget constrained and unconstrained dynamic facility layout problems

The main characteristic of today's manufacturing environments is volatility. Under a volatile environment, demand is not stable. It changes from one production period to another. To operate efficiently under such environments, the facilities must be adaptive to changing production requirements. From a layout point of view, this situation requires the solution of the dynamic layout problem (DLP). DLP is a computationally complex combinatorial optimization problem for which optimal solutions can only be found for small size problems. It is known that classical optimization procedures are not adequate for this problem. Therefore, several heuristics including taboo search, simulated annealing and genetic algorithm are applied to this problem to find a good solution. This work makes use of the ant colony optimization (ACO) algorithm to solve the DLP by considering the budget constraints. The paper makes the first attempt to show how the ACO can be applied to DLP with the budget constraints. In the paper, example applications are presented and computational experiments are performed to present suitability of the ACO to solve the DLP problems. Promising results are obtained from the solution of several test problems.     

Neural networks in production planning and control

The purpose of this paper is to present a selection of the most significant ANN (artificial neural network) applications used to solve PPC (production planning and control) problems. Therefore, the paper itself is a reasoned classification rather than a simple survey. The PPC domain is divided into various areas, and for each area one or more examples of ANNs are discussed, together with the benefits and drawbacks of their application to that particular area. Finally, two case studies developed by the authors are reported and discussed to analyse the main implementation problems to be considered when using ANNs.     

Collaboration with Caveats: Research–Practice Exchange in Planning

Abstract

Researcher and practitioner collaboration in urban planning is both critical to good outcomes and problematic to achieve in reality. Collaboration has the potential for new partnerships, better research problem definition, improved research design and greater impact on practice and policy. However, politics, stakeholder agendas and funding bodies bring pressures and constraints, for which research professionals require a broader set of skills to manage. We examine researcher–practitioner collaboration as part of an action research project on urban greening in Australia. Focusing on a stakeholder engagement workshop, we examine the mechanisms used to overcome barriers to research-practice exchange. We find overt consideration of common barriers to access and use of research when planning collaboration exercises can help facilitate more productive engagement, creating spaces for mutual understanding and generating shared objectives. However, we also find that efforts at collaboration challenge traditional research practices, involve tensions and caveats, and require a different mode of researcher engagement.     

Understanding and Planning for Freight Movement in Cities: Practices and Challenges

ABSTRACT

Planning for freight presents a perpetual challenge for governments. Understanding freight flows has attracted increasing research attention, though such knowledge can be difficult to translate to address problems in planning practice. This paper critically assesses the challenges of understanding and planning for urban freight movement, especially with reference to achieving more sustainable outcomes. In doing so, we elucidate guidance for broader analytical and policy approaches suited to meeting diverse public interest objectives. We review the literature with specific reference to the nature of policy problems, while collating existing conceptual knowledge for broad urban land use types.     

Disability,Terror and Safety in the City: Charting Individuals’ Spatio-temporal Encounters with Counter-terrorism Measures in Birmingham,UK

ABSTRACT

This paper responds to recent calls for further work on vulnerable people’s experiences of official planned attempts to create safe cities that are based on ableist assumptions. Go-along interviews elicited from people with cognitive, physical or motor impairments, together with interviews taken from built environment professionals are used to highlight the diverse ways in which differently disabled individuals encounter official efforts to create safe, secure urban spaces and suppress terrorist threats in one UK city centre (Birmingham). Focusing on individuals’ embodied spatio-temporal experiences provide wider lessons for planners and urban stakeholders about the decision-making processes people adopt during urban crises.     

Guest Editorial Production Planning and Control in other Industries

This paper provides an excursion into various scheduling problems arising in the manufacturing environment and possible approaches that can be taken to solve them. It reviews the research in production scheduling from the perspective of designing and operating a production system and examines the research strategies adopted to find the solution of the practical problems. This review is in the form of the paradigms that evolved during the twentieth century and shows the transition in theory and practice of each paradigm. It covers the fundamental frameworks of scheduling theory, outlining various approaches that can be taken to solve (optimally or approximately) such problems, and the difficulties arising in their practical use. Subsequently, an iterative scheduling process is suggested as an extension of existing paradigms to solve practical production scheduling problems and to bridge the gap between theory and practice in production scheduling and control.     

How smart cities transform operations models: a new research agenda for operations management in the digital economy

Abstract

The notion of smart cities is growing in prominence in the digital economy. The integration of urban infrastructures with information and communication technologies enables the development of new operations models. Digitised infrastructures offer opportunities for public and private organisations to design and deliver more customer-centric products or services, particularly for those that require geographical proximity with consumers in the online to offline (O2O) context. A framework is developed and used to analyse three case examples. These cases illustrate the emergence of new operations models and, demonstrate how smart cities are redefining the characteristics of operations models around their scalability, analytical output and connectivity. We also explore the feasibility, vulnerability and acceptability of each new operation. This paper contributes to our understanding of how smart cities can potentially transform operational models, and sets out a research agenda for operations management in smart cities in the digital economy.     

Italian Urban Plans: Diversified Approaches and Methods for Assessing Their Quality

This article poses the difficult task of providing a brief overview of Italian urban planning, difficult to understand for foreign observers because each Region has different legislation and urban planning tools. The paper describes an original methodology that evaluates the quality of the approach differentiated as (1) ‘of the plan’ (reformist, participative, from the territory); (2) ‘in the plan’ (integrated strategic, sustainable); (3) ‘with the plan’ (conformative, methodological, recompositional, systemic-infrastructural); and (4) ‘beyond the plan’ (beyond governance methodologies). The paper also compares aspects of quality present in plans for large, medium and small Italian cities. The conclusions review factors of excellence that may be used in other international scenarios.     

Making Competitive Cities in the Light of the Meta-SWOT Tool: A Case Study of Tehran,Iran

ABSTRACT

While there is a growing body of scholarship on regional competitiveness, little attention has been paid to the planning methods that can pursue this objective. Public planners are mainly relying on conventional methods that have come under increasing criticism. This study aims to introduce Meta-SWOT as a novel planning tool in urban and regional studies. Meta-SWOT provides competitive and realistic strategies for planners. It systematically tries to present strategies rooted in internal resources and capabilities while acknowledging the challenges posed by the external environment. Nevertheless, it has several limitations that should be considered when applying to urban and regional planning.     

Finding symbolons for cyberspace: Addressing the issues of trust in electronic commerce

E-commerce is growing rapidly, but a majority of the Internet users is still hesitant to become involved in it. One big hurdle is lack of trust. This paper deals with trust in ecommerce and measures to increase it. It discusses one particular so-called web assurance service for business-to-consumer commerce in detail. It also analyses if such services remain viable in an era of more mature e-commerce, and how they should be adjusted to the business-to-business environment.     

Comparative evaluation of genetic algorithms for job-shop scheduling

Many optimization problems from the industrial engineering world, in particular the manufacturing systems, are very complex in nature and quite hard to solve by conventional optimization techniques. There has been increasing interest in imitating living beings to solve such kinds of hard optimization problems. Simulating the natural evolutionary process of human beings results in stochastic optimization tech niques called evolutionary algorithms, which can often outperform conventional optimization methods when applied to difficult real-world problems. There are currently three main avenues of this research: genetic algorithms (GAs), evolutionary programming (EP) and evolution strategies (ESs). Among them, genetic algorithms are perhaps the most widely known types of evolutionary algorithms today. During the past years, several GAs for the job-shop scheduling problems have been proposed, each with different chromosome representation. In this paper, the different GAs are collected from the literature and an attempt has been made to evaluate them. The benchmark problems available in open literature are used for evaluation and the performance measure considered is makespan. The algorithms are coded in C+ +.     

COMMON DUE-WINDOW SCHEDULING

In this paper, we solve common due-window scheduling problems within the just-in-time window concept, i.e., scheduling problems including both earliness and tardiness penalties. We assume that jobs share the same due window and incur no penalty as long as they are completed within the due window. We further assume that the earliness and tardiness penalty factors are constant and that the size of the window is a given parameter. For cases where the location of the due window is a decision variable, we provide a polynomial algorithm with complexity O(n * log (n)) to solve the problem. For cases where the location of the due window is a given parameter, we use dynamic programming with pseudopolynomial complexity to solve the problem.     

A re-analysis of the occupational stress indicator

Abstract

This paper investigates the reliability of the Occupational Stress Indicator (OSI). Data from a sample of university staff, drawn from all areas of an urban university, are used to reassess the apparently low reliabilities of many of the OSI subscales reported by Cooper et al. (1988). In addition, factor analysis results are reported for the first time for the sources of pressure data. The reliability data reported here, while higher reliabilities than originally obtained, remain unacceptably low. A lack of stability in the device as it is currently formulated seems apparent. The paper also presents for the first time a detailed analysis of the sources of pressure scale, indicating a solution different from that proposed by Cooper et al. (1988). Certain areas of the OSI clearly need refinement; the inclusion of locus of control and type A behaviour as personality variables in particular is called into question. Observations regarding the particular strengths and weaknesses of this device, and suggestions for future refinements, are offered.     

Twenty Years after the Hot Autumn: Work and Politics in Italy from Rupture to Change

Abstract. In the first paper the authors make a critical analysis of the interpretations and models generally used for it caso italiano(the Italian Case) and propose explanations that are not one-sided, and that take into account all the elements of continuity which characterised the various phases of these last twenty years. The second paper examines the institutional features of the Italian industrial relations system, and underlines its ‘constant characteristic’. that is. its under-institutionalisation. The author emphasises the negative effects of these institutional shortcomings, and shows concern that the much exalted ‘flexibility’ of the Italian system could be detrimental, rather than positive, as it derives from these shortcomings. The note by Guido Romagnoli. attempts to use some theoretical statements on union behaviour, as the key to interpret the events of the Italian case. The author then indicates some aspects and reasons for the crisis of Italian unions. The fourth paper examines the relationship of the unions with the Italian political system over the last twenty years. This article suggests that it is characterised by considerable continuity in stabilising this political system, both in phases of strength and in times of weakness. This stabilising role has. however, not been reciprocated; in fact, not only has the political system not stabilised the unions and industrial relations, but has become a major obstacle to their strategic reorientation. The last paper in this group of essays on the Autunno Caldo offers what could be termed an ‘institutional’ explanation of union continuity, analysing the various phases of collective mobilisation. political exchange and flexibility, and examines the relationships between the social actors during these phases. The selection of papers published here is in memoriam of our colleague and friend Guido Romagnoli, who suddenly died shortly after the conference. For this reason it includes the outline that he presented at that conference which he could not develop into a full article.     

The Potential of Integrated Urban Deposit Modelling as a Cultural Heritage Planning Tool

Researchers investigating human settlements from an archaeological perspective have long recognized that the urban landscape provides a particular set of challenges and demands. Building on the formative Arup study [Ove Arup and Partners (1991) York Development and Archaeology Study (London: English Heritage)], urban deposit modelling as a heritage planning tool has been developed for some time; however, its use has not become widespread. There are however recent intellectual and technical developments that enhance integrated deposit modelling and reveal potential as a curatorial tool for the management of the historic environment. These relate to three key developments: the improvement and enhancement of 3D modelling and visualization techniques, conceptual changes around categories such as ‘made ground’ and the formation of research agendas for the urban historic environment. This paper will explore an example of the difficulties inherent in combining differently scaled datasets whilst also outlining the potential and the significance of urban deposit modelling in, often deeply stratified, historic northern European cities.     

Spatial Planning in Ghana: Exploring the Contradictions

The purpose of this research is twofold: to explore the complexity of spatial plan preparation and implementation in Ghana using Kumasi as a case study; and second, to examine the contradictions of spatial plans and ‘actual development’ occurring in Kumasi. Using social science research methods (semi-structured interviews) and physical survey (land use plans), findings indicate that spatial planning in Kumasi is a bureaucratic process hijacked by urban planning agencies with limited involvement of urban residents. As a result, urban development is considerably influenced by spontaneous informal development patterns (i.e. self-organization). This phenomenon of self-organization is expressed in a context of uncertainty created by weak spatial planning system which encourages haphazard development. Regrettably, in Kumasi, self-organization is often overlooked by spatial planning agencies as they focused on rigid and exclusionary spatial plans. This paper advocates consideration and integration of self-organization processes in spatial planning efforts to respond adequately to the urban development challenges confronting Kumasi.     

Women and technology: A review of training initiatives

Abstract

This paper considers the entry of women into technological areas of work, their subsequent career progression and return to work after a career break. It considers the development of those training programmes and related initiatives which have attempted to encourage girls and young women to enter non-traditional areas of work, and others which help women return to work after a career break. It emphasizes that such training needs to address the psychological and social issues which arise, as well as provide for new technical knowledge and skills. In doing so it reviews some of the courses which are currently available and comments on their apparent success. In its concluding problems it refers to the on-going problem of funding such training and of providing a supportive database.     

Business patterns within telecommunications

The global telecommunications changed from a number of co-operating national monopolies offering a restricted range of services to a competitive, growing market with players of many types and sizes, offering a large range of services. How can vertically integrated incumbents align themselves and their systems to best compete in this environment? Business patterns and enterprise modelling offer a tool to model a large organization as a number of smaller enterprises that can compete with and co-operate with smaller specialist players in the market. In order to identify enterprises, this paper proposes that there are only a limited number of types of enterprise (manufacturer, service supplier, reseller, that these enterprise types can only interact in a limited number of ways (component supply, aggregation supply, resell supply, trading, end-supply and commission). With the use of examples, this paper illustrates these types of enterprise and enterprise relationships, and how they can be combined to build both internal and external supply chains, and discusses some of the conclusions that can be drawn from this analysis.
