Professional education in urban planning: A framework for growth

Expanded interest in socio-economic problems have created new opportunities for the urban planning profession. Because of their emphasis on physical and land-use aspects of the city, traditional educational programs in urban planning have been unable to deal adequately with these new opportunities. Changes in program orientation and emphasis to meet these new challenges have started to take place in some urban planning departments. It remains to be seen how effective some of these changes will be over the long run.

This paper considers some current aspects of urban planning education. The role of professional education in our society is examined along with the role of science in planning. Based on this analysis, a framework is proposed for the future growth of professional education in urban planning. Because of its strong orientation towards a “science of planning”, this proposal appears to be somewhat different than other changes currently being considered in some urban planning programs.     

Spatial strategies of the “haredi” population in Jerusalem

The purpose of this article is to discuss the strategic behavior—spatial and social—of the “Haredi” (ultra-orthodox) Jewish population. This behavior is associated, in essence, with self-segregation and social isolation accompanied by spatial expansion.

This study deals with these processes in one of the largest concentrations of the ultra-orthodox Jewish community—the northern neighborhoods of Jerusalem. The Jewish ultra-orthodox community is characterized by its special interpretation of Jewish law (halacha) and by its high degree of cohesiveness. It tends to segregate itself from the Israeli population for two main motives. The positive one is the desire to create and maintain “cultural dominance” in a specific area in which the community lives and functions. This includes considerations of scale economies and concentration economies in the provision of the special goods and services which it consumes. The second motive, a negative one, is the desire to avoid some kinds of contacts and interactions with the various groups which do not observe Jewish law according to the orthodox conception. This is done in order to prevent the transfer of secular cultural values of western society into their domain.

The high communal cohesiveness, coupled with high population growth and a strong desire for self-territorial segregation, results in increased pressure on the urban residential space. The fear of social relationship—which may serve as agents for transferring social or cultural values—results in a high degree of intolerance toward the non-religious Israeli population. The contact lines between the two populations have become, therefore, confrontation areas which are characterized by territorial conflicts.

Study of the directions of the territorial expansion suggests what the spatial strategy of the ultraorthodox community is: to gain control of a whole, well-defined urban space in order to maintain cultural dominance in it, while assuring potential directions for expansion in the future. The relationships with the outside, non-religious population is built on a modus operandi principle: i.e. minimal and culturally neutral interactions.

This strategy is carried out through penetration and expansion tactics in a well-known process. These processes present important challenges for planning areas in which ultra-orthodox communities reside.     

Social indicators and social accounts

This paper defines “social indicators” as statistics which have two denning characteristics. They are, first, measures of direct normative interest; that is, what the economist would call measures of “welfare” and “illfare”. Most existing government statistics are not of this type, because a large proportion of existing statistics are measures of government or other institutional activity, produced as a by-product of accounting or administrative routine. The second defining characteristic of a social indicator is that it should fit into a systematic scheme of classification or aggregation which would make possible a balanced assessment of socio-economic progress or retrogression in some broad area, as well as disaggregated and detailed study of particular problems.

The work in government on social indicators was designed in part to meet the needs of Toward a Social Report, a preliminary study of the condition of American society issued by the U.S. Department of Health, Education, and Welfare (Superintendent of Documents, Wash. D.C. 20402; 1969). Social indicators can also fit, with other statistics, into a set of “policy accounts” or scheme of social accounting, which would relate social expenditures to the social indicator they were designed to affect. This would encourage broadened cost-benefit analysis and rational public decision-making.     

The computer imperative

“The Computer Imperative” has been defined as the necessity for the administrator to specify his goals, objectives, criteria, standards, rules, etc., in very explicit and operational terms as he seeks to devise a better management system, especially if computers will be used to implement portions of the system. It is essential that educational leaders be able to tell system designers and computer technologists what they want, and to do this they must know at least the rudiments of what is technically possible. Otherwise, the administrator in some sense is at the mercy of the technologist. Studying an administrative system as essentially an information system provides a useful model. To define who originates, processes, uses, or needs information is to describe much of the actual operation of administration. In a manual system, many rules and procedures can be left undefined, and intuition and experience can substitute effectively for logical precision. As computers are programed to assume certain basic transactional functions, the administrator must bear in mind that computers do only what they are told. It is therefore critically important to be able to describe what we want. Much of the “threat” of automation can be attributed to uneasy or uncomfortable recognition of this “imperative”.     

An extremal and information-theoretic characterization of some interzonal transfer models

The paper develops a method of deriving gravity models from extremal principles. The prototype result yields the most popular gravity flow model characterized by an extremal principle. This principle is also for the first time elucidated as an information-theoretic one of choosing the distribution of interzonal transfers which gives least “information” (in the technical sense) for discrimination against a distribution reflecting the “facility” (reciprocal of the “difficulty”) of travel between zones.     

Mathematical analysis applied to school attendance areas

The objective of this paper is to develop a generalized mathematical model of pupil assignment within school districts. This model can then be used to examine various policies of student integration. Proposed bussing schemes, school location policies, educational parks, attendance boundaries, etc., can be tested for cost, travel time or other measures of efficiency. Extension to other areas of educational planning is feasible.

Mathematical programming techniques are used to assign resources (say school children) to facilities (say schools) subject to restrictions on facilities (say capacity limits) and resources (say a maximum travel time or a desirable range of school “mixtures”) so that a measure of performance, the “objective function” (say total cost or total time of travel) is optimized. The model is intended to allow examination of a wide range of objective functions and system constraints.     

Load-limited order release in job shop scheduling systems

This report examines the practice of using work load limits to control the release of orders to a job shop. Load limits function in the following general way. Whenever the inventory of work at a work center exceeds some critical value (its “load limit”), further release of orders which are routed to that work center are blocked from entering the shop. After the inventory is “worked off,” release of work to the shop gateways is again permitted. Load-limited order release is intuitively appealing because it appears to be a method for reducing system inventory and flow times. The practice of load limiting order release is becoming popularized by some of the recent production planning software products now on the market. A notable example is OPT. In this report, analytical results for an M/M/1 queueing model, along with existing simulation studies of multi-machine job shops are interpreted to form a theory about the effects of using load limits.The major finding here is the proposition that system flow time, inventory, and order tardiness all deteriorate to the extent that load limits introduce idle time into the schedule. Based on the arguments presented here, a very cautious approach toward the use of input control schemes for anywhere but gateway work centers would be advised. The conclusions drawn here are to a great extent arrived at by interpreting the research results of others, so there is a clear need for further research which tests these assertions in a more direct and controlled way.     

The air diffusion model as an urban planning tool

The air above a city is scarce and thus should be considered an urban resource. As a resource, air affects the urban population in several ways. First, the quality of this resource is important, it provides amenities to the urban dweller and enters into his site selection process. Second, because this mass is constantly in motion, it provides a diffusion mechanism through which externalities, or economic “bads”, are exchanged throughout the city.

In this article, we will develop a statistical air diffusion model that explicitly defines this exchange process. The model is then employed to examine two opposing theories of zoning justification—the property value theory and the planning theory. In examining the latter, the importance of air quality and its movement to the design and implementation of the comprehensive urban plan is emphasized.

“This urban system is no longer composed of separate, autonomous places with country in between but is a complete eco-system. A new urban ecology is in the making. Man is no longer able to step temporarily out of the framework of his own structuring or to move on elsewhere to escape the unforeseen consequences of his ingenuity, ruthless energy or folly”     

Shifts in autonomy, responsibility and control from centre to periphery in public administration: the case of the ministry of finance in Italy

In tackling administrative reform and in the hope of improving the effective allocation of resources, most European governments have shown a growing interest in adopting private sector management models in the public administration. The assumption underlying this paper is that the decisive variables in the different national contexts have to do with the relationships between the central and the peripheral administrative levels, and the way in which administrative actors at the two levels interpret their roles and participate in the reform process. The paper examines the case of the reform of the Italian Ministry of Finance. In seeking to improve its performance and the services it provides, the ministry reform is intended to introduce a management system in which the key concepts are the planning, programming and control of administrative action and results. According to reform rhetoric, shaping a new class of administrative managers at the local level is the crux of the question. However, research results hint that the “creation” of this new local executive staff is yet to be completed. The working hypothesis advanced is that this is due to local executives’ lack of confidence in the “system”, inasmuch as the reform process has so far been characterised by a tendency to give them responsibility without autonomy and autonomy without control. The greater their lack of trust, the lesser their willingness to risk the consequences of failure and the greater their tendency to stick to defensive positions and to return to previous “bureaucratic” conceptions and ways of operating.     

Systems engineering approach in residential land planning

Residential land planning, which is concerned with the physical development of land for residential use, is a multidisciplinary activity wherein the physical planner, engineer and architect play very prominent roles. Cost is paramount for low-income households. Therefore, in residential land planning for producing lots for this economic group, all possible efforts have to be made for reducing the cost per lot consistent with acceptable standards. To achieve this objective, residential land planning should be concerned not only with physical planning but should also take into account the interaction between the spatial design, the architectural design of the dwelling and the design and layout of utility systems so that the cost per lot including the service connection cost is minimised. In the paper, the systems nature of the residential land planning problem has been discussed and a cost-optimisation model for obtaining the optimum physical design of a planning module (a unit of design) fulfilling the given constraints has been developed using the technique of geometric programming. Application of the model is illustrated with a number of example problems using the field data, which show large cost differences from one system solution to another. This establishes the need for such an approach if cost reduction is the primary objective. The geometric programming technique of optimisation adopted in the paper could be used by a designer in the smallest design office with the help of a low-cost programmable calculator and the programmes developed by the author.     

The cultural significance of accounting in Japan

We have had a spate of works on “Japanese Management” in the world, but very few on “Japanese Accounting”. In this article it is made clear that the functioning of accounting is contingent on the culture in which the accounting systems are incorporated, and that in order to discuss this intermingling of accounting and culture a perspective elaborated in Scandinavia can be relevant despite the uniqueness of Japanese culture. For only non-rationalistic or “naturalistic” perspectives can provide a basis for understanding the cultural dynamics of Japanese organizations and Japanese society. Thus the roles of accounting in Japan go far beyond what has been discussed in accounting textbooks.

Feasibility of national population growth targets in LDC's

This study employs a simulation model and data on desired family size to evaluate feasibility of national population growth targets. A basic claim is that neglect to consider desired family size in population planning has resulted in spurious target setting by a number of governments. It is proposed that if presently attainable family size is below desired family size in any society i, then low utilization of family planning services can be expected to continue as a function of absence of demand. Policy implications of this claim for allocation of scarce international family planning funds are discussed.     

An application of a spatially distributed queuing model to an ambulance system

An application of a spatially distributed queuing model to an ambulance system is presented. The purpose of this research was to assess the usefulness of a variation of the “hypercube” queuing model developed specifically for modeling an ambulance system. The model was applied to the emergency medical system of Greenville County, South Carolina using historical data. Results indicate that the model provides reasonably accurate estimates of system performance measures when the input parameters can be accurately specified.     

Street-lighting projects selection: A rational decision making approach

The study presented in this paper represents a new and fresh approach to the problem of efficiently and optimally allocating scarce resources in the provision of public services—namely, street-lighting. The methodology developed is aimed at introducing more systematic and rational thinking in a way which is both technically and politically feasible. To the best of the author's knowledge, the study presents, for the first time, a procedure for the comprehensive quantitative estimate of the utility accruing from street-lighting. The utility value derived from each street-lighting project depends upon several factors, some of which can be technically assessed and others estimated only by subjective values.

In order to deduce the subjective values, the Delphi method was employed. This method permits derivation of subjective values for groups of interviewees whose assessments may reasonably be assumed to be crucial in determining the relative values of the objectives of the utility function. Those components of the utility function representing subjective values were identified and estimated.

The conventional practice, whereby residents have no explicit say in the planning of the lighting system in their city, was abandoned. Residents' value judgements concerning the relative importance of the objectives to be gained by the lighting system were incorporated into the planning process. An optimization model based on an integer programming algorithm was employed because it permits periodic (e.g. annual) selection of a set of indivisible projects to be realized during a given period. This enables maximum economic and social utility to be derived, subject to budgetary and technological constraints.

The selection process was extended and deepened so as to render it sensitive to benefit from economies of scale and external economies. The optimization process was carried out with the use of an IBM-MPS X (an integer programming algorithm). The methodology was applied to a large and diverse quarter in the city of Jerusalem that is divided into seven semi-homogeneous neighborhoods—in terms of their physical as well as their socio-economic and demographic characteristics. This represents a very different approach when compared to the conventional way in which the planning design and installation of street-lighting projects are currently carried out.     

A new pattern of risk management: The Hyogo Framework for Action and Italian practise

On January 2005, the World Conference on Disaster Reduction adopted the “Hyogo Framework for Action 2005–2025: Building the Resilience of Nations and Communities to Disasters” [UN-ISDR (United Nations, International Strategy for Disaster Reduction), Disaster Risk and Sustainable Development: understanding the links between development, environment and natural hazards leading to disasters, World Summit on Sustainable Development, August–September 2002, Johannesburg, 2002]. This “white paper” seeks to promote “an effective integration of disaster risk considerations into sustainable development policies, planning and programming at all levels” [UN-ISDR (United Nations, International Strategy for Disaster Reduction), Disaster Risk and Sustainable Development: understanding the links between development, environment and natural hazards leading to disasters, World Summit on Sustainable Development, August–September 2002, Johannesburg, 2002. p. 1] outlining a strategic and systematic approach to reduce vulnerabilities and risks to hazards.

The current paper discusses each aspect of the Hyogo approach in relation to the Italian experience. Italy represents an interesting case because of its multiple hazard environment, and the fact that it has developed an integrated approach to risk reduction planning. Strengths and weaknesses of the “Italian way” of dealing with risk are identified, and compared with the theoretical processes suggested by the framework. Implementation of selected key actions in Italy has helped identify a series of obstacles to progress, further defining the gap that still exists between theoretical framework and actual practise.

The various activities constituting “risk management” (viz., assessment, prevention, mitigation, monitoring, early warning, preparedness) are here considered in a comprehensive framework wherein each phase is connected to the others. The paper focuses on natural hazards, which are more frequent in Italy (landslides, floods, earthquakes, volcanic eruptions, natural soil erosion). The main results include:

• A new process for dealing with risk, using the framework for guidance, is identified. We track the reasons for Italy gradually adopting this process in dealing with her vulnerabilities to natural hazards.

• Those factors that appear to interfere with an integrated approach to risk management are identified as a function of selected experiences.

• Guidelines for analysing vulnerabilities to disaster in a multi-hazard, integrated context are proposed.

A budget model of a university

Yale University operates a number of budget systems for purposes of planning and control. These include a capital budget, a cash budget, an operating budget, and an operating growth budget. The operating growth budget might be the one of most potential interest to people concerned with Operations Analysis in Education.

The operating growth budget is a model of what the University fiscal flows and structure might look like under varying conditions over an extended period, e.g., 20 years. It is composed of a set of ideas, a set of equations, and a computer program.

It is important to us to point out that this work is in a development stage. We have run many simulations, adjusted the program, refined the parameter estimates, and modified the questions we have been asking. Part of our efforts have followed a concern that we have captured the appropriate structure, part that we are investigating our own spectrum of decisions, and part that we can reflect the varying “external” conditions outside of the University's immediate influence and control.

Our work with the operating growth budget has already started to influence some of the decisions of the University including the yearly operating budget, the capital funds programs, and the endowment investment portfolio.
