Abstract

Dense-urban construction is reported to affect the social and economic welfare of surrounding residents and local businesses in various ways. However, research studies and practical methodologies aimed at assessing to what extent the choice of a construction plan that reduces such effect are very limited. The objective of this paper is to present the development of an automated assessment methodology to fill this research gap. To this end, two formulations are presented; one based on multi-attributed utility functions and the other based on monetary compensations for disruptions caused by construction operations. Both formulations assess the impacts of construction plans on (1) increased travel distance; (2) residents' relocation; (3) business loss; (4) business closure; and (5) noise inconvenience. The proposed automated methodology is implemented in five sequential phases and utilizes Geographical Information Systems (GIS) and Visual Basic Application (VBA). Using the proposed implementation, the two alternative formulations are applied to an infrastructure upgrading project in Cairo, Egypt that had five possible construction scenarios. While the two formulations resulted in the same preference order for the five scenarios, they exhibited different performance in terms of their (1) assessment relative values; (2) required input data and robustness; (3) ease of results interpretation; and (4) comprehensiveness and scalability. The developed framework shows promising results in terms of identifying and sorting the major root causes of the socioeconomic disruptions caused by dense urban construction. Results show that using the proposed methodology informs decision-making and planning at the early stages of a project, which in turn helps to reduce cost overruns and schedule delays.

Abstract

WZIAT was first introduced to work zones in 1995 following a Strategic Highway Research Program (SHRP)-sponsored study (Agent & Hibbs, 1996). Since the SHRP program, several WZIATs have been developed, evaluated by departments of transportation (DOTs) and implemented in work zones on many highway projects. [...]the researchers investigated the potential usefulness of WZIATs on reported fatal work zone intrusion cases. [...]the researchers identified and evaluated work zone fatality cases captured in the NIOSH Fatality Assessment and Control Evaluation (FACE) program to determine whether WZIATs could have prevented the reported fatalities. [...]construction and maintenance workers are provided additional reaction time if an intrusion occurs before the activity zone.

Abstract

Brazil's main housing program, Minha Casa Minha Vida (MCMV), has contracted the construction of over 3 million housing units since 2009, providing access to homeownership for low and middle-income households through a combination of credit, subsidies and guarantees. In this paper, we analyze disaggregated delinquency information at the project level for the section of the program that serves households in the lowest income range (Faixa 1). Our analysis of program performance in six metropolitan regions shows an overall level of delinquency of 28% as of the end of 2015. We identify four hypotheses to explain this elevated level of delinquency: the peripheral location of the units, insufficient income to cover ongoing costs, moral hazard in the management of the program, and organized crime in some projects. Our analysis shows that in 4 of the 6 regions, low-income projects in peripheral locations exhibit substantially higher non-payment levels and that lower income households have higher levels of delinquency. Based on our analysis, we recommend modifications to program design, including the inclusion of location criteria in subsidy scaling. The findings provide evidence of the limits of MCMV Faixa l's approach to solving Brazilian low-income housing needs and contribute to an emerging body of literature pointing to the importance of location in housing programs.

The Consuming Mob: Bargain Shopping in the City

Abstract

This paper examines the representation of the crowd as the consuming mob in the American department store in the early twentieth century. In store promotions and popular accounts, urban retail spaces provide the setting for the materialization of the crowd as the driving engine and mutated body of mass consumption. Store owners and their backers employed the image of shopping hordes on their premises as an advertisement for the success of modern trade. The department store served as a model of a rational utopian order in its operations and spaces. But in popular representations the growing assemblies of bodies and goods often appeared as a potentially unruly force that threatened the constraints of their surroundings. This paper will trace the path of the urban crowd as it flowed from the city streets into the inner recesses of the store, mapping narratives of shopping through the lenses of gender and class.

Abstract

Open water evaporation (E-ow), such as evaporation of lake and reservoir, is typically estimated by observations of different pans. The observation networks of pan evaporation (E-pan) were established and maintained worldwide for a long history. All the pans in the world consist of water body and pan wall, which includes side wall, pan rim and (if any) pan bottom. Since the pan wall will affect E-pan by radiation absorption and heat conduction, once pan wall absorbs and conducts more heat for vaporizing than water body in a pan, observed E-pan dynamics will greatly deviate E-ow causing uncertainties and errors in estimating E-ow. Thus, this study calculated E-pan at 767 meteorological stations in China and quantified the contributions of water body and pan wall on E-pan trends. For China as a whole, E-pan decreased at -3.75 mm/a(2) and increased at 3.68 mm/a(2) during 1960-1993 and 1993-2016, respectively. 84% of E-pan trends were contributed by water body. For 767 stations, E-pan trends of 84 and 96 stations were dominated by pan wall during 1960-1993 and 1993-2016, respectively. Since pan wall contributed more than half of E-pan trends for (similar to)23% of the stations in China, the impacts of pan wall on E-pan dynamics cannot be ignored.

Abstract

Historic built environments of the modern colonial era survive in cityscapes of former colonies the world over, often featuring largely in the projected urban identities of cities in Africa, Asia, and the Middle East. Tunisia is no exception. The complex relationships between extant architectures of colonialism and current users, designers, and preservationists there are shifting within the context of contemporary globalization. Though ties between Europe, France, and Tunisia are less overt than they once were-now taking the form of international development loans, professional and educational exchanges, tourism programmes, popular culture and the media-they are nonetheless significant in their sustained influence. This article explores the nature and products of neocolonialism in postcolonial heritage management and tourism practices, using several case studies from Tunis including curated medina walking tours, the renovation of the Avenue Bourguiba, and expansion of the renowned Bardo Museum. Rather than dismissing contemporary preservation and tourism management practices, the article invites further debate regarding the influence of foreign actors, conservation approaches, and potential alternatives for the future of heritage management in a rapidly changing Tunisia.

Dynamic Production Scheduling Model Under Due Date Uncertainty in Precast Concrete Construction

Kim, Taehoon; Kim, Yong-Woo; Cho, Hunhee. (2020). Dynamic Production Scheduling Model Under Due Date Uncertainty in Precast Concrete Construction. Journal Of Cleaner Production, 257.

View Publication

Abstract

Precast concrete structures (PCs) are widely used in the construction industry to reduce project delivery times and improve quality. On-time delivery of PCs is critical for successful project completion because the processes involving precast concrete are the critical paths in most cases. However, existing models for scheduling PC production are not adequate for use in dynamic environments where construction projects have uncertain construction schedules because of various reasons such as poor labor productivity, inadequate equipment, and poor weather. This research proposes a dynamic model for PC production scheduling by adopting a discrete-time simulation method to respond to due date changes in real time and by using a new dispatching rule that considers the uncertainty of the due dates to minimize tardiness. The model is validated by simulation experiments based on various scenarios with different levels of tightness and due date uncertainty. The results of this research will contribute to construction project productivity with a reliable and economic precast concrete supply chain. (C) 2020 Elsevier Ltd. All rights reserved.

Abstract

Background: Studies have shown associations between neighborhood disadvantage and alcohol misuse among adults. Less is known about the role of neighborhood context in young adults (YAs), who engage in more disordered forms of alcohol use compared to other age groups. Using data collected monthly, this study examined whether YAs reported more alcohol use and consequences when they were living in neighborhoods with greater concentration of poverty. Method: This study used data from 746 participants aged 18-23 years living in the Seattle, WA, region. Surveys were administered each month for 24 consecutive months. Measures included typical number of drinks per week and past month count of alcohol-related consequences. Residential addresses at each month were geocoded and linked to census-tract level percentage of households living at or below poverty threshold. Multilevel over-dispersed Poisson models were used to estimate associations between standardized monthly deviations in tract-level poverty from one's average and alcohol outcomes. Results: Across 14,247 monthly observations, the mean number of typical drinks per week was 4.8 (SD = 7.4) and the mean number of alcohol consequences was 2.1 (SD = 3.5). On months when they were living in neighborhoods with higher levels of poverty than their average, participants reported significantly higher levels of alcohol consequences (Count Ratio = 1.05; p = .045). Conclusion: YAs may engage in more problematic forms of drinking when they reside in neighborhoods with higher levels of disadvantage. During a time of frequent residential changes, YAs moving to more disadvantaged neighborhoods may benefit from additional supports.

Abstract

Housing affects health, yet health is seldom considered in housing decisions. Health impact assessment (HIA) is a tool that can improve housing-related policies, plans, programs, and projects by bringing together scientific data, health expertise, and stakeholder engagement to identify the potential health effects of proposed decisions. We systematically identified and reviewed HIAs of housing decisions in the United States, yielding 54 HIAs between 2002 and 2016. Two examined federal proposals; the others explored decisions in 20 states. A variety of organizations led the HIAs, including non-profits, public health departments, and academic institutions. The primary decision-makers each HIA sought to inform were housing, planning, and/or elected officials. Eighteen HIAs focused on housing policies, codes, design elements, and utilities in residential structures. The remaining 36 HIAs included housing as one element of broader community development and transportation planning decisions. HIA recommendations changed decisions in some cases, and the assessment process helped strengthen connections between public health and housing decision-makers. To illustrate key characteristics of housing HIAs, we purposefully selected three HIAs and described the decisions they informed in detail: off-campus student housing in Flagstaff, Arizona; a rental housing inspections program in Portland, Oregon; and revitalization plans for a major thoroughfare in a suburb of St. Louis, Missouri. With a few exceptions, federal, state, and local agencies in the U.S. are not required to consider the health impacts of housing decisions, such as where housing is sited, how it is designed and constructed, and policies for ensuring that it is affordable and safe. HIA has emerged as a tool for advocates, health and housing practitioners, and policymakers to fill this gap. However, few studies have examined whether HIAs do in fact change housing decisions, shift the way that decision-makers think, or ultimately shift determinants of health (e.g., housing affordability and quality). This review demonstrates that HIAs can facilitate the consideration of health during housing decision-making. Housing HIAs can also help decision-makers address commonly overlooked effects, such as changes to social cohesion, and improve civic participation by engaging communities in the decisionmaking process.
