A goal programming model for the siting of multilevel EMS systems.

Facility siting models known as location covering techniques have proven to be useful particularly for emergency medical services (EMS) planning, given the importance of ambulances responding to demand within some maximum time constraint. These models represent a set of methods which focus the health planner's attention on the access of people to health care, since they attempt to “cover” people in need of service within some specified time standard.This research develops a technique for the locational planning of sophisticated EMS systems, characterized by multiple levels of emergency health services. Specifically, a two-tiered system with “basic life support” and “advanced life support” capabilities is modeled as a goal program.By applying location covering techniques within a goal programming framework, this study develops a method for the siting of multilevel EMS systems so that (1) each service level maximizes coverage of its own demand population, and (2) “back-up” coordination between levels is assured. The usefulness of this goal program as a health planning tool is evidenced in the model's explicit articulation of EMS policy objectives and its ability to link system levels in terms of “goal-directed behavior”. The working of this multilevel covering model is demonstrated by reference to EMS planning scenarios and related numerical examples.     

On the possibility of positive rent gradients

The negative rent gradient is a virtually unanimous prediction of urban residential land rent models and a condition of locational equilibrium. This is the result of treating urban rents solely as location rents, where location is defined in terms of accessibility to the CBD. Urban rent may include another component, “externality rent,” which could, for instance, reflect neighborhood externalities in the form of area amenities and pleasant living environments. Introducing externality rent as an element in urban rent makes a positive rent gradient possible, provided that the externality is internalized in the land market. Conditions for a positive rent gradient are determined for both the identical and unequal incomes cases.     

Economic Methodology and Nobel Laureates: Confirmation of a Methodological Paradigm Shift

Meir Kohn ( 2004 ) argues that two methodologies, the “value paradigm” and the “exchange paradigm,” dominate modern economics with the equilibrium‐focused value paradigm increasingly replaced by the more successful exchange paradigm. This article examines the question of modern economic methodologies and seeks to determine if the shift described by Kohn can be seen in the winners of the Nobel Prize in Economics (1969–2010). Trends in Nobel laureates suggest that Kohn's depiction of the two paradigms and their relationship appears accurate.     

Implications for food production potential of future urban expansion in Ontario

The paper describes the application of an evaluation system to assess the flexibility that would exist in the use of Ontario's agricultural land resources under alternative urban growth scenarios. A programming method is employed, but the analysis does not yield a “best” or “predicted” allocation of land use; rather, the system gauges the degree to which options in the use of land are affected by changes in conditions, and identifies those land areas which are strategically important for particular uses given the specified conditions. The conditions are specified to reflect possible patterns of urban and exurban development, both with and without policy controls. The analysis provides evaluations of both the pressures on the land resources if food production requirements are to be met, and the importance of particular land units for agriculture if the requirements are to be met, under the alternative urban growth scenarios.     

An evolutionary complex systems perspective on urban health

Deliberations about how to govern complex problems of urban health and wellbeing sustainably have often been implicitly biased by ideas such as being ‘human-scale’ or ‘people-centered.’ With increasing urban populations and increasing urban system interconnectivity, many cities have transformed into city regions or clusters, and the external effects of urban growth are carried mainly by the marginalized and the environment putting urban health increasingly at risk. Here we address the question of why human societies have not been better at collectively adapting to the challenges of urbanization and global environmental change? We build a theoretical framework of multi-level selection, complex systems evolution, and governance, following which we then present ‘human-scale’ and ‘people-centered’ ideas of urban development as expressions of two types of socio-political organization with different degrees of self-organization. We found several reasons for which the maladies of current urban development emerged and the seeming inability to resolve them. First, urban systems became increasingly interconnected and evolved into ultrasocial superorganisms, displaying preference to sustain themselves as a whole rather than their subordinates. Second, the difference in scaling effects between the biological and the social network contributed to the mismatch between rapid urban growth and slow adaptation. Furthermore, institutions of decreased variety reinforce themselves and become dominant, creating a positive feedback mechanism and promoting invasive and exploitative exponential growth, but they also reduce the creativity and resilience of urban systems. We also found that both the “human-scale” and the “people-centered” approaches acknowledge the exponential growth and decreasing variety in urban systems, and advocate for correcting the mismatches. To incorporate people's needs and values for long-term, truly sustainable urban health governance, we recommend combining the self-organizing, evolutionary feature of “human-scale” and the coordinative, political feature of “people-centeredness.”     

On The "Stickiness' Of The Economic Equilibrium Paradigm

Abstract . Thomas S. Kuhn, Imre Lakatos and Mark A. Zupan have made important contributions to our understanding of why paradigms of thought tend to be quite resistant to displacement, or even revision. Their work is extended in an attempt to explain the staying power of the economic equilibrium paradigm. It is argued that this paradigm is particularly “sticky” due to its pedagogical, methodological and protective properties. The implications of this for paradigm assessment and evolution are discussed.     

Dogmatic trends in marxist sociology

The research program of theoretical pluralism would imply for sociology, to confront marxist with nonmarxist sociology. This seems useful only if both sociologies are refutable in principle. However, certain principles of marxist sociology prevent the refutation of its most fundamental hypotheses. This is shown in analyzing an often cited book by E. Hahn. The “basis” of marxist sociology is historical materialism. Thus, if hypotheses from marxist sociology are falsified, historical materialism is falsified too. Hahn maintains-without presenting any empirical evidence-that historical materialism has found the solution of all problems and thus cannot be refuted. Marxist sociology, however, is-according to Hahn-falsifiable. This statement and the thesis mentioned before are inconsistent, for if historical materialism is true, marxist sociology-which follows from historical materialism-cannot be wrong. But even if there would be no inconsistency, the following situation would be possible: Marxist sociology proves entirely wrong, but historical materialism (the “basis” of marxist sociology) will not be abandoned. Furthermore, Hahn maintains that by means of empirical research (observation and experiment) the central hypotheses of marxist sociology cannot be tested, namely the “essence of appearances.” But he is at a loss for arguments; so every hypothesis can be immunized against falsification by declaring that it describes the “essence” of certain “appearances.” One further strategy of immunization Hahn introduces, is the rule that in an explanation only marxist laws may be used. So it is not possible to confront marxist and nonmarxist hypotheses. This rule eliminates a very effective kind of criticism, namely the confrontation of inconsistent theories.     

Environmental quality,expenditure patterns and urban location: Effects on income groups

The incidence of environmental quality is related to urban socio-economic groups in Canada. The study firstly is concerned with the distributional implications of expenditures for goods and services that are “heavy polluters”, and secondly with the incidence of urban environmental quality on the residents of Montreal, again in terms of impact on income classes. The econometric investigation is cross-sectional and provides base-line information of immediate importance to the social planner, and permits the assessment of changes in the distributional impacts of pollution for areas where the majority of Canadians now live.     

Self-renewal of the Japanese firm and the human resource strategy

Traditional “Japanese personnel management” that has long been considered as the key for Japan's competitive success now needs fundamental restructuring in order to meet the challenges of a stagnant economy, matured domestic market, and the rise of NICs (Newly Industrialized Countries) in international markets. The self-renewal of Japanese firms can be achieved by a paradigm shift at the corporate strategy level: from a production orientation to a product orientation. In accordance with this paradigm shift, leading Japanese firms have started reforming their Human Resource Management (HRM) function from a productivity-centered to a creativity-centered one— creative HRM. Creative HRM has three pillars: (1) the creation of the strategic vision through commitment of the employees, (2) an entrepreneurial middle management as a key strategic node, and (3) multi-dimensional personnel management. Creation and realization of the strategic vision through the active commitment of an entrepreneurial middle management is necessary for the self-renewal of the firm. “Japanese Personnel Management” that might have been overadapted to the traditional strategic paradigm is now transforming itself from a “group-centered” personnel administration to an “individual-centered” one. While Western companies have been adopting Japanese “groupism” to reconstruct their production systems, Japanese companies have started introducing Western “individualism” to encourage creative self-transformation. But no system or technique is truly effective without human commitment, and this requires a fundamental paradigm shift for Japanese firms.     

Cooperative choice and its framing effect under threshold uncertainty in a provision point mechanism

This paper explores how threshold uncertainty affects cooperative behaviors in the provision of public goods and the prevention of public bads. The following facts motivate our study. First, environmental (resource) problems are either framed as public bads prevention or public goods provision. Second, the occurrence of these problems is characterized by thresholds that are interchangeably represented as “nonconvexity,” “bifurcation,” “bi-stability,” or “catastrophes.” Third, the threshold location is mostly unknown. We employ a provision point mechanism with threshold uncertainty and analyze the responses of cooperative behaviors to uncertainty and to the framing for each type of social preferences categorized by a value orientation test. We find that aggregate framing effects are negligible, although the response to the frame is the opposite depending on the type of social preferences. “Cooperative” subjects become more cooperative in negative frames than in positive frames, whereas “individualistic” subjects are less cooperative in negative frames than in positive ones. This finding implies that the insignificance of aggregate framing effects arises from behavioral asymmetry. We also find that the percentage of cooperative choices non-monotonically varies with the degree of threshold uncertainty, irrespective of framing and value orientation. Specifically, the degree of cooperation is highest at intermediate levels of threshold uncertainty and decreases as the uncertainty becomes sufficiently large.     

Wage gradients,rent gradients,and the price elasticity of demand for housing: An empirical investigation

As developed in Muth's “Cities and Housing,” attainment of locational equilibrium within an urban area implies a necessary functional correspondence between wage and price gradients and the compensated price elasticity of demand for housing. In this paper estimates of the rent and wage gradients are utilized to generate price-elasticity estimates via this equilibrium correspondence. The Box-Cox transformation technique is used with data from the metropolitan Chicago area to test for the functional forms of the wage and rent gradients. The optimal maximum-likelihood functional forms for both gradients yield a price-elasticity estimate of ?0.40.     

The Male-Female Comparable Worth Debate: Alternative Economics Perspectives on an Issue That Cuts Across the Social Sciences

Abstract . Writers and speakers on the “comparable worth” or “pay equity” issue refer to “the economic view” but there is no such consensus. Three major paradigms exist in labor economics, the neoclassical, the “radical” or Marxian or Neomarxian, and the institutional Each differs in philosophical orientation, employs different analytical methods, and leads to different policy implications. On the issue of pay equity for women their views are contrasted; differences center on how successfully the market extends full options of choice. The analysis indicates that incremental advances in the direction of pay equity are to be expected, given present incentives in the private sector and less economic constraints in the public sector, provided women continue economic, legal, and political pressure. Surveying The Literature on the comparable worth or pay equity debate, one often encounters reference to the economic view. In reality however, three major paradigms exist in labor economics today; the prevailing neoclassical paradigm, the radical or Marxian view, and the institutional approach. While the three can be viewed as sharing common objectives (to describe, to predict, and to prescribe) they approach issues from different philosophical frameworks, employ different analytical tools, and lead to very different policy implications. Examining the pay equity issue from the perspectives of the three paradigms suggests different insights into the issue than that usually labelled the economic view.     

An exploratory analysis of the effect of the “buy it now” option on sellers' revenues in silent auctions

• This paper tests three competing hypotheses regarding the effect of a “buy it now” option in silent auctions: that the option has a positive, negative, or neutral effect on the seller's revenues. These hypotheses were tested on 4 years of data from a university art museum's silent auctions. The results indicate that the “buy it now” option has a significant negative effect on the seller's revenues. Possible explanation, implications, and limitations are discussed.

A journey of social sustainability in organization during MDG & SDG period: A bibliometric analysis

Organizational sustainability is a multi-facet paradigm widely used to address perennial business challenges such as climate change, industrial waste, the economies of scale and social well-being, etc. In the last three decades, extensive research has been performed on ecological or economic sustainability, ignoring the third pillar of sustainability. Given the importance of humans and society-a center-stage of inclusive development-this paper aims to conduct a bibliometric analysis to examine the growth of organizational social sustainability (OSS) from 2000 to 2021 during MDG & SDG periods. A total of 1566 publications are analyzed using Scopus and the Web of Science (WoS) database. Citation networks, bibliographic coupling, and thematic mapping have explored influential work, intellectual structure, and research gaps. The study findings demonstrated that most publications are during the SDG period, with Sustainability as the most productive journal and the USA as the most contributing country. The top 10 active institutions are from Australia, France, and Spain. The top contributing authors are from France, but the USA is at the top in citations. Contributions are lacking from large portions of Africa. Keyword analysis showed that “social sustainability,” “sustainable development,” “environmental sustainability,” “sustainable supply change management,” “circular economy,” and “social life cycle assessment” are the main topics. Keyword analysis and thematic mapping show that despite increased publications in the field of organizational social sustainability, OSS research is still far from focusing on the stakeholders' benefits, satisfaction, and subjective well-being. Moreover, quantitative assessment of OSS based on sustainability standards such as Global Reporting Initiatives (GRI) and Value Reporting Foundation (VRF) standards was found scant in the given field. The present research concluded with scope and opportunity for future research in the area of OSS.     

The dark side of competition: Modeling status games

Though “teams” are supposed to work together for the benefit of the firm, suboptimal outcomes may emerge when individuals within a team are more concerned with their own status and outcomes relative to their “teammates,” behaving as if they are competitors. Using a version of the stag hunt coordination game, we develop hypotheses regarding the role of status and competitiveness on coordination on Pareto optimal solutions. We test these hypotheses using three studies, with manipulations for both role and status. Status is found to play a significant role, resulting in suboptimal outcomes for competitors but not teammates.     

海尔“人单合一”管理模式的演化路径及其价值实现机理——基于波粒二象性的理论视域

“人单合一”模式的演化路径可以用“人”“单”之间相互作用关系的变化过程进行描述,这一路径也可概括为“人的价值实现”从无到有地创生涌现,再形成一种独立力量,对“人单合一”体系以及各组织要素进行反向影响和塑造的过程。无论是表面上的二重性特征,还是在内涵层次、演化路径和发展趋势方面,“波粒二象性”与“人单合一”都具有紧密的对应契合性。文章在分析比较“波粒二象性”与“人单合一”对应契合关系的基础上,结合“人”与“单”之间由“分化对立”到“互补转化”再到“整合创新”关系转化的过程,分析阐释了海尔“人单合一”管理模式的演化路径及其价值实现机理。“波粒二象性”不仅为“人单合一”的内涵转变以及发展路径提供了机理解释,而且从跨学科的视角出发,为组织的管理实践与创新变革提供了思路启示。     

Environmentally driven mode of business development: a management control perspective

A prerequisite for successful business development is that the control system is designed and used in such a way that strategically important areas can be planned and followed up. Thus, it must be possible to relate results on the quality front, for example, to the company's strategy, which is why quality systems are often integrated with the overall system of control. Environmental management systems, on the other hand, often tend to lead a life of their own, quite disconnected from the overall control system with its routines for strategic planning and follow-up. This can perhaps explain why environmental work has not become a natural part of corporate business development, despite the market for environmentally friendly products. In this article, we therefore focus particularly on control systems and their role in the promotion of an environmentally driven mode of business development. It appears that the integration of environmental management systems with other control systems has been found to be important. The tentative model presented here indicates the conditions under which such integration is possible. It also shows how a company's approach to environmentally driven business development can fall into various phases. The model includes three dimensions: (1) strategy, (2) control systems, and (3) attitude to environmental work. A number of hypotheses are formulated regarding the importance of these dimensions for the successful promotion of an environmentally driven mode of business development in large companies. The article concludes with some suggestions as to how the model can be used in further research.     

Occupation and the journey-to-work: Some further analysis

This paper examines the impact of occupation upon commuting distances in the Toronto Census Metropolitan Area (CMA). Specifically, from the residential and job location patterns of each occupational group a “minimum distance” indicator of the degree of job-residence access of each occupational group is developed with the aid of a linear programming transportation model. The differences in “minimum distance” that must be travelled by the members of each occupational group are explained. The actual distances travelled to work by the members of each occupational group are then investigated and attempts are made to separate the determinants of each occupational group's average journey-to-work distance into two main factors—job residence access and propensity to commute. On the basis of the locational patterns, the analysis suggests that job residence access was generally greater for blue-collar workers than for white-collar workers. Although occupation did have an impact, then, on journey-to-work distance through its influence upon locational patterns of job and residence, little evidence of its effect on the propensity to commute was found. Rather, the results suggest that the main determinant of this factor was sex since female workers exhibited a far lower disposition to commute than did their male counterparts.     

The new regionalism in the Americas: a theoretical framework

This paper concerns the “new regionalism” of the last decade, as opposed to the “old regionalism” of the 1950s and 1960s. I first argue that the new regionalism is taking place in a world fundamentally different from that of the old regionalism, so that old-regionalism-theory is not necessarily relevant. I then present an explanation for why neighbors might integrate, relevant to why integration might occur in the Americas. This gives prominent roles to political economy, direct investment, and fundamental economic reform, and de-emphasizes the old trade creation versus trade diversion trade-off. It also implies a diversity of approaches to regional integration.
