This research was aimed at exploring levels of equity in accessibility to employment and education in the city-region of Bogotá, Colombia's capital city. Building on consolidated methodologies for the assessment of potential accessibility, we estimate accessibility indicators at the zone level, evaluate how potential accessibility varies among income groups, and present evidence related to transport mode, in order to analyze social and spatial inequalities produced by the distribution of accessibility to employment and education activities. The research incorporates a method to evaluate how accessibility varies among zones according to average income and mode of transport in order to produce evidence-based arguments that can inform transport policy in the city-region of Bogotá, and other similar contexts in the Global South. Our results show strong distributional effects of the socio-spatial and economic structure of the city-region, its transport infrastructure and services, and the effect of current transport and land-use policies for citizens of different income groups. The tools and empirical evidence in this research seek to contribute to informed policy development in Latin America and other developing contexts, and feeding current debates on the role of accessibility in addressing social and spatial inequalities stemming from urban mobility.

Public transport has claimed a preferential position in recent urban development agendas internationally. Rising interest on inclusive development of cities at different levels of urban policy involves new opportunities and challenges for increasingly urban societies. In cities of the Global South, in addition to institutional and physical challenges for the development of efficient and inclusive public transport, local governments face the challenge of making public transport affordable for a large share of the population in conditions of poverty. In order to meet these challenges, several public transport systems throughout have implemented targeted subsidies for specific social groups such as students, the elderly and people with reduced mobility, and more recently for the poor. The government of Bogotá has implemented a pro-poor public transport subsidy scheme that aims at alleviating the em. This research develops an analysis of the effects of such subsidy from an accessibility perspective using potential accessibility measures to employment opportunities and assess its impact on equity. The research builds on the hypothesis that accessibility is a multidimensional construct that can benefit from the decrease in economic as much as gains in time costs. Results from the analysis show that both the current structure of the pro-poor subsidies in Bogotá and alternative scenarios for increasing its coverage are progressive, improving accessibility and equity for those with access to the subsidy. The paper provides valuable insights for the analysis of similar policies in other urban contexts in the Global South.

The relationship between transport, poverty and social exclusion has increasingly held an important place in both research and policy agendas, particularly in industrialised countries. While this has helped consolidate an emerging body of theory concerned with the social consequences of mobility, our understanding of these dynamics in the context of high vulnerability and poverty in the global south is still relatively undeveloped. Through the case of Soacha, a municipality adjacent to Colombia's capital-Bogotá, this paper explores travel strategies in a context of scarce provision of transport which, when combined with acute conditions of low-income and segregation, limit vulnerable populations' access to the city. The travel practices, perceptions and priorities of low-income populations in deprived areas of the global south are analysed, using a framework of transport-related social exclusion, to critically examine the elements that play a role in gaining access to the city. The emergence of adaptable methods, relations and transactions between demand and supply that allows deprived populations to reduce their risk of becoming socially excluded show potential for conceptual and practical development in addressing and analysing transportrelated social exclusion.

Context: Dosing parameters are needed to ensure the best practice guidelines for knee osteoarthritis. Objective: To determine whether resistance training affects pain and physical function in individuals with knee osteoarthritis, and whether a dose-response relationship exists. Second, we will investigate whether the effects are influenced by Kellgren-Lawrence grade or location of osteoarthritis. Data Sources: A search for randomized controlled trials was conducted in MEDLINE, Embase, and CINAHL, from their inception dates, between November 1, 2018, and January 15, 2019. Keywords included knee osteoarthritis, knee joint, resistance training, strength training, and weight lifting. Study Selection: Inclusion criteria were randomized controlled trials reporting changes in pain and physical function on humans with knee osteoarthritis comparing resistance training interventions with no intervention. Two reviewers screened 471 abstracts; 12 of the 13 studies assessed were included. Study Design: Systematic review. Level of Evidence: Level 2. Data Extraction: Mean baseline and follow-up Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores and standard deviations were extracted to calculate the standard mean difference. Articles were assessed for methodological quality using the CONSORT (Consolidated Standards of Reporting Trials) 2010 scale and Cochrane Collaboration tool for assessing risk of bias. Results: The 12 included studies had high methodological quality. Of these, 11 studies revealed that resistance training improved pain and/or physical function. The most common regimen was a 30- to 60-minute session of 2 to 3 sets of 8 to 12 repetitions with an initial resistance of 50% to 60% of maximum resistance that progressed over 3 sessions per week for 24 weeks. Seven studies reported Kellgren-Lawrence grade, and 4 studies included osteoarthritis location. Conclusion: Resistance training improves pain and physical function in knee osteoarthritis. Large effect sizes were associated with 24 total sessions and 8- to 12-week duration. No optimal number of repetitions, maximum strength, or frequency of sets or repetitions was found. No trends were identified between outcomes and location or Kellgren-Lawrence grade of osteoarthritis.
