An investigation of the frequency of squatting facets in Later Stone Age foragers from South Africa

Distinctive morphological changes attributed to a habitual squatting posture were observed on the distal femur, distal tibia and on the talar neck of Later Stone Age (LSA) foragers. The frequency of squatting in LSA foragers (n = 56) was determined by the presence of anatomical features of joint hyperflexion. Three South African comparative skeletal groups from different time periods were also analysed: skeletal remains of early farming populations (n = 17), 18th century ‘Free Blacks’ and/or slaves from Cobern Street, Cape Town (n = 21), and a modern cadaver sample (n = 29). The results show that 28 out of 56 LSA foragers (50%) were habitual squatters; 13 out of 17 farmers (76.5%) and one of 21 individuals from the Cobern Street collection (4.8%) demonstrated squatting facets. No anatomical squatters were found in the modern cadaver sample. There was no significant sex difference between squatters and non‐squatters. Hence at least half of the LSA foragers and farmers were habitual squatters, according to the signs of joint hyperflexion. Squatting is a comfortable position for those used to it because the body weight is supported with minimal muscular activity. Two probable reasons are suggested for the difference in postures adopted by the different groups: (1) availability or lack of availability of furniture and (2) cultural and individual differences in resting posture.

SEARCH FRICTIONS,UNEMPLOYMENT, AND HOUSING IN CITIES: THEORY AND POLICIES

We propose an urban search‐matching model with land development. Wages, unemployment, prices of housing and land are endogenously determined. We characterize the steady‐state equilibrium and then discuss the issue of efficiency. To explore interactions among markets, we implement comparative static analysis. We also consider three policies: an entry‐cost policy that reduces firms' entry, a transportation policy that reduces commuting costs, and a housing policy that decreases rental prices. We find that the transportation and housing policies are more efficient if the unemployment rate is low, while the entry‐cost policy is more efficient if the unemployment rate is high.     

Policy Instrument Choices for Growth Management and Land Use Regulation

What factors account for local government land use practices and their choices among specific growth management policy instruments? We apply the political market framework to examine how land use policy choices in Florida are shaped by institutional features of county governments and the demands of organizations and interests in a community. Local policy decisions reflect a balance of the conflicting interests and responses to economic and political pressures. The results demonstrate that county government structure and election rules play critical roles in the adoption of urban service boundaries, incentive zoning, and transfer of development rights programs. We report evidence consistent with the argument that these “second‐generation” growth management policies are motivated by exclusionary goals.     

Policy of Delay: Evidence from a Bayesian Analysis of Metropolitan Land‐Use Choices

Do local policymakers strategically use delay in permitting development to forestall the growth machine? The mantras of smart growth and sustainable development assume local governments can balance the competing values of economic development, ecology, and equity interests in a community. We employ a political market framework to explain differences in local government land use decisions. This framework conceptualizes policy choices as resulting from the interplay between the aggregate policy demand by residents, developers, and environmental interests and the aggregate supply by government authorities. Delays can be imposed strategically through processes of development approval by city governments where industry strength and form of government vary within county‐level service‐delivery fragmentation. We utilize novel Bayesian multilevel modelling of data collected from 2007 and 2015 surveys of Florida city planners and find strong institutional effects and multilevel relationships.     

Vacuums and Veils: Engaging with Statistically ‘Invisible’ Indigenous Population Dynamics in Yamatji Country,Western Australia

Although much is known about broad trends in Australian Indigenous geographies, particular aspects of Indigenous spatiality continue to be rendered invisible by standard statistical measures. The national census, for example, only registers moves at one and five year intervals. Any mobilities enacted within these timeframes are not measured. Yet these statistically ‘un‐captured’ mobility processes are often integral to Indigenous lived experiences and have a significant dialectical relationship to government service delivery processes. Understanding these population dynamics is therefore a critical, though underdeveloped, consideration within geographic enquiry and contemporary debates about State and Federal Indigenous policy directions and initiatives. This paper presents qualitative research findings regarding local experiences and perceptions of Indigenous spatiality in Yamatji country, Western Australia. Within this grounded framework, the paper builds on existing literature by drawing out some of the common spatial, temporal and demographic characteristics, or dimensions, of statistically un‐captured Indigenous mobility processes. With this discursive, albeit generalised and malleable, typology established, the analysis turns to a reflection on some of the methodological and conceptual complexities of measurement, interpretation, and translation of these mobility processes across the policy‐research nexus.     

Land Policy and Farming Practices in Laos

The government of Laos has identified the eradication of poverty as a priority. Given the primarily agricultural character of the country, it has selected land reform as a core policy to reach this goal. The policy has two major aims: to increase land tenure security in order to encourage farmer involvement in intensive farming, and to eliminate slash‐and‐burn agriculture to protect the environment in a country still rich in forest resources. State intervention takes the form of land allocation, a process which combines the protection of some areas of village land with the formal recognition of private ownership in authorized farming areas. In a country with different types of geography, the effects of the policy are variable, but the research presented in this article demonstrates that the land laws have shortcomings which allow for differing interpretations depending on the local social relationships. Since local specificities are not taken into account, the reform is proving counterproductive for both forest protection and agricultural modernization, as well as having a negative social impact by marginalizing the poorest farmers.     

Performing Rootedness in the Negev/Naqab: Possibilities and Perils of Competitive Planting

Through ethnographic and historical analysis of the Negev region of Israel, this article examines competitive planting as a common tool in land conflicts. In a context of disputed land ownership, some Bedouin Arab residents plant crops in defiance of government policy. Government enforcers of land‐use regulations destroy many of these crops and engage in counterinsurgent tree‐planting. I suggest that planting is such a potent tactic because it draws on “environmental idioms” of agricultural labor, the rootedness of trees, and a fundamental Jewish‐Arab opposition that have been central to the development of both Israeli and Palestinian nationalisms. For Bedouin Arabs, whose relationship to both nationalisms has long been contested, the multivalent symbolism of planting makes it a particularly promising tactic for asserting land claims. Further, I contend that these plantings demonstrate both the power of environmental idioms to structure land claims along ethnic lines and the creative potential of participants to challenge dominant environmental discourses by adding new connotations.     

Learning policy—the contextual curtain and conceptual barriers

Many European states are now giving attention to strategic planning as a means of coordinating and democratizing local government. The UK government is not alone in seeing some form of ‘community planning’ as a means of promoting closer sectoral integration in policy‐making and service delivery while also encouraging public participation. This suggests scope for comparative research to inform lesson drawing, especially from Norway, which has been rolling out kommuneplan at the municipality level since 1985. Cross‐national lesson‐drawing is hazardous, however, given the different legal, political and cultural traditions which make policies ‘work’ in particular local settings. In this article these difficulties are acknowledged and ethnographic research is used to explore further problems in lesson‐drawing, especially the very different ways in which concepts of participation and integration are given meaning in particular national contexts. Through comparative ethnographies of community planning processes in Asker Municipality, Norway, and South Lanarkshire Council, Scotland, remarkable similarities are revealed in the language and objectives of the planning documents in each setting, but show that this belies important differences in the relations between administrative and political domains, in the governing role of plan statements, and in the underlying theories of democracy.     

Political Structure and the Limits of Recognition and Representation in Ghana

Recent studies of democratization in sub‐Saharan Africa often focus on government recognition granted to traditional authorities. This article examines northern Ghana, where chiefs of a minority group are denied formal recognition but pressure state officials to recognize their status as land custodians. This leads to contests and debates between state officials, chiefs and communities over whether the customary institutions have in fact been recognized for what they claim to be. The article uses episodes of contention to nuance conceptualizations of recognition as a specific relationship between actors and institutions, and as a question of government policy or choice. Recognition and non‐recognition are contested in a grey zone of social constructions. Non‐recognition persists as a continuation of colonial policy, state law path trajectory, and state officials’ endeavours to stay out of ‘traditional’ affairs. However, customary rights to land are validated by the new local government institution, and chiefs use newfound positions to expand their jurisdictions. Stakeholders affirm unequal social categories underpinning different understandings of recognition. The article examines contentions that hinge on interpretations of who is recognizing and not recognizing whom, and actors’ efforts to reshape and reproduce political structures.     

Positive Returns and Equilibrium: Simultaneous Feedback Between Public Opinion and Social Policy

This paper pushes forward political research from across disciplines seeking to understand the linkages between public opinion and social policy in democracies. It considers the thermostatic and the increasing returns perspectives as pointing toward a potentially stable set of effects running between opinion and policy. Both theoretical perspectives argue that opinion and policy are reciprocally causal, feeding back on one another. This is a general argument found in opinion‐policy literatures. However, much empirical research claims to model “feedback” effects when actually using separate unidirectional models of opinion and policy. Only a small body of research addresses opinion‐policy endogeneity directly. In this paper I consider an opinion‐policy system with simultaneous feedback and without lags. I argue that there is a theoretical equilibrium in the relationship of opinion and policy underlying the otherwise cyclical processes that link them. Given that available cross‐national data are cross‐sectional and provide limited degrees of freedom, an ideal theoretical model must be somewhat constrained in order to arrive at empirically meaningful results. In this challenging and exploratory undertaking I hope to open up the possibility of a general system of effects between public opinion and social policy and how to model them in future research. I focus on social welfare policy as it is highly salient to public interests and a costly area of government budgets, making it an area of contentious policymaking. Social policy is also a major part of the thermostatic model of opinion and policy, which was recently extended to the cross‐national comparative context (Wlezien & Soroka, 2012) providing a critical predecessor to this paper because identification of equilibrium between public opinion and social policy in any given society is greatly enhanced through comparison with other societies. This counterfactual approach helps to identify opinion‐policy patterns that may not change much within societies, but can be seen as taking on discrete trajectories between societies.     

Punctuated Equilibrium Theory and the Diffusion of Innovations

This article builds on punctuated equilibrium theory to evaluate the diffusion of public policy innovations in the United States. The article argues that punctuated equilibrium theory provides a unifying framework for understating three mechanisms leading to the diffusion of innovations: gradual policy diffusion driven by incremental policy emulation, rapid state‐to‐state diffusion driven by policy imitation and mimicking, and nearly immediate policy diffusion driven by state‐level responses to a common exogenous shock. Drawing upon the Bass mixed influence diffusion model, this research generates measures of the coefficients of external and internal influences for diffusion for 81 public policy innovations that have spread across the United States. The article then evaluates how the policy image and direct participation of the federal government contribute to distinct patterns of diffusion over time.     

A connectivity model as a potential tool for smart specialization strategies

The article contributes to the smart specialization literature by presenting a new approach, connectivity analysis, where Triple Helix (TH) relations (involving universities, companies and government) are at the centre of the entrepreneurial discovery process. Relations between helices may be seen, from the point of departure of proximity, as preconditions of connectivity, or interaction, measured through expectations and experiences. This offers potential solution to two limitations of proximity approach: its static nature and narrow focus on dyadic relationships. The connectivity analysis reveals the extent of mutual expectations, as well as tensions, or gaps. Based on this analysis, the article presents a policy model that is used to map structures of networks and gaps between TH actors. It may also identify strengths, weaknesses and problems. This analysis is used as input to structured dialogues between actors in leading positions in the TH and in smart specialization policy-making and implementation. This approach may lead to policy interventions supporting entrepreneurial discoveries. The model has been developed in partnership with researchers and the Regional Council of Ostrobothnia. The article also presents this case study and demonstrates the use of the connectivity model in practice.     

Policy Change and Policy Stasis: Comparing Swiss Foreign Policy toward South Africa (1968–94) and Iraq (1990–91)

This article investigates how concepts from the field of public policy, in particular the Advocacy Coalition Framework (ACF) initially introduced by Sabatier and Jenkins‐Smith, can be applied to the study of foreign policy analysis. Using a most similar comparative case studies design, we examine Switzerland's foreign policy toward South Africa under apartheid for the period from 1968 to 1994 and compare it with the Swiss position toward Iraq after the Iraqi invasion of Kuwait in 1990, when the Swiss government imposed—for the first time—comprehensive economic sanctions against another state. The application of the ACF shows that a dominant advocacy coalition in Swiss foreign policy toward South Africa prevented a major policy change in Swiss–South African relations despite external pressure from the international and national political levels. Actually, quite the opposite could be observed: Swiss foreign policy increased its persistence in not taking economic sanctions against the racist regime in South Africa during the 1980s and early 1990s. The ACF, with its analytical focus on policy subsystems and the role of external shocks as potential triggers for change, provided a useful framework for analyzing the factors for policy change and stasis in Swiss foreign relations toward the selected two countries.     

Can national cultural policy approaches be used for sub‐national comparisons? An analysis of the Québec and Ontario experiences in Canada

There has been relatively little comparative research undertaken on sub‐national cultural policy. This article aims to contribute to the development of sub‐national comparative studies by assessing the utility of national cultural policy approaches for comparative research at the sub‐national level in Canada. Drawing on studies of national cultural policy, the authors develop three main approaches to cultural policy and administration – the French, British and hybrid approaches – and explore their applicability to the origin and evolution of cultural policy and administration in the Canadian provinces of Québec and Ontario. This exploratory research suggests there is room for optimism in drawing on national‐level experiences to undertake sub‐national comparative cultural policy research, particularly for comparisons over broad time periods. The study also suggests that it will be important in subsequent research to further elaborate the models for present‐day comparative analysis and to refine and adapt them to reflect specificities at the provincial level of analysis.     

Optimal Allocation of Land between Productive Use and Recreational Use

Abstract This paper is an inquiry into the optimal allocation of time and natural areas to recreational uses, which have the feature of being a pure and continuous public good. We address this issue with a comprehensive approach. A static rational general equilibrium framework is developed in which heterogeneous agents allocate land and time endowments between alternative uses. This modeling has important advantages. First, Pareto‐optimal and voluntary‐contribution equilibrium allocations are obtained in a unified set‐up. Second, the suboptimality result of the decentralized equilibrium, the free‐rider problem on the provision of this nonexcludable public good, and different mechanisms to return the economy to its first‐best are analyzed. Finally, a methodological critique is made of some empirical literature, and it is suggested that our theoretical microeconomic‐based structure seems to be a suitable starting point for empirical research.     

Dispossession 1990s style: Aborigines,islanders and the policy making process of the Goss labor government

Aboriginal and Islander people in Queensland remain unempowered in the policy making process of government. This is achieved by downgrading and under‐resourcing the relevant portfolio, by co‐locating it with welfare, by giving other departments statutory rights in decision making on indigenous issues which are not reciprocal, by relocating key indigenous policy areas into otherwise antagonistic departments, by ghettoising the issues in Cabinet and by failing to elucidate clear policy guidelines on indigenous issues. The Goss government has also ensured that indigenous people remain unempowered outside of government by failing to legislate for regional land councils, Aboriginal majority on national parks boards of management and an Aboriginal‐controlled statutory acquisitions fund and by retaining excessive discretionary power in the administration of the 1991 Land Acts.     

NEW DIRECTIONS FOR URBAN ECONOMIC MODELS OF LAND USE CHANGE: INCORPORATING SPATIAL DYNAMICS AND HETEROGENEITY*

ABSTRACT We review the usefulness of urban spatial economic models of land use change for the study and policy analysis of spatial land use–environment interactions. We find that meaningful progress has been made in econometric and monocentric models extended to account for multiple sources of spatial heterogeneity and in the development of general equilibrium models with spatial dynamics. Despite these advances, more work is needed in developing models with greater realism. Most agent‐based computational models of urban land use change currently lack economic fundamentals, but provide a flexible means of linking microlevel behavior and interactions with macrolevel land use dynamics. In combination with empirical methods to identify parameters, this framework provides a promising approach to modeling spatial land use dynamics and policy effects.     

Industry policy under the accord: Reform vs traditionalism in economic management

During the emergence and implementation of the ALP‐ACTU Accord, commentators havé paid comparatively little attention to its industry‐policy aspect. But the Accord itself rests on important changes in Australian unionism, its new priority in employment policy and ambition to participate in policymaking in general. These changes have now crystallised in a more penetrating analysis of manufacturing decline and demands for industry‐policy reform within the framework of the Accord. The Hawke government, however, has fallen under the influence of an older, institutionalised tradition of Australian economic management that is frustrating the attempt to use industry policy to return to maintainable full employment and assert the labour movement's social priorities. The present conflict over industry policy thus represents a major threat to the Accord.     

Mode Choice,Commuting Cost,and Urban Household Behavior*

Abstract. In this paper, we extend the partial equilibrium urban model of DeSalvo (1985) to include mode choice. DeSalvo demonstrated that the urban model of Muth (1969) was robust to the extension to leisure choice. We show that the model is robust to mode choice as well. In addition, we derive the comparative static results that commuters choose higher speed modes for longer commutes, at higher wage rates, with greater tastes for housing, and with lower housing prices. Also, for a given distance commuted, we derive the comparative static result that commuters chose shorter duration commutes at higher wage rates. Whereas it is typically assumed that marginal commuting cost is positive and non‐increasing with distance, we derive these results. Moreover, we derive the results that marginal commuting cost rises with an exogenous increase in housing price and falls with increased tastes for housing. We also explore the effects of exogenous commuting‐cost changes on the endogenous variables of the model. The remaining comparative static results on housing consumption and location are qualitatively the same as in DeSalvo.
