Serving Queensland: reflecting on geographical access to the pelvic exenteration service in Queensland.

Pelvic exenteration for rectal cancer involves a radical multi-visceral resection to improve complete surgical clearance, and access is limited within Queensland. A retrospective review of a prospective database of the referrals to the pelvic exenteration service in the Royal Brisbane and Women's Hospital from 2009 to2023. Geographic, as well as clinical and demographic information was collected. One hundred and seventy six patients were referred to the pelvic exenterations service. In total 93 patients were referred from a major city, 52 from inner regional areas, and 31 from outer regional or remote areas. One hundred and three referred patients (58.5%) proceeded to surgery, significantly more of whom were referred from a major city (P < 0.001). Of the patients referred from outer regional, inner regional, and major cities, a similar proportion of patients proceeded to surgery (55%, 52%, and 63.4%). Patients not proceeding to surgery in major cities and inner regional areas were most commonly unfit to proceed, whereas in outer regional areas most patients decided against surgery (61.5%). In the 14-year period, overall referrals increased, with inner regional referrals increasing the most over time. Overall survival was not significantly impacted by remoteness. Awareness of the pelvic exenteration service in regional Queensland may have resulted in less referrals to the service. It is important to confirm a broad-reaching service to optimize patient care.

Estimates of Air Pollutant Emissions by Vehicle Fleet in the State of Pará, Brazil: Impacts and Trends

Objective: aims to estimate emissions of the main atmospheric pollutants from vehicular sources in the state of Pará, to continue the environmental agenda of monitoring air quality. Theoretical Framework: The growing global concern about air quality in urban areas is driven by the environmental and public health impacts caused by air pollution. The concentration of pollutants from vehicle sources represents one of the main challenges, especially in densely populated regions such as the capital and other major cities in the state of Pará, where the automotive fleet has increased significantly. Method: The methodology used combined "bottom-up" and "top-down" methods to calculate emissions of carbon monoxide (CO), nitrogen oxides (NO) and total hydrocarbons (HC) for different vehicle categories and fuel types. Data on licensed vehicle fleets and fuel consumption obtained from DETRAN-PA and ANP were used. Results and Discussion: The results revealed that gasoline-powered vehicles are responsible for the majority of CO and HC emissions, while diesel vehicles emit the largest amounts of NO into the atmosphere. Motorcycles were identified as the largest source of emissions due to their larger number in the circulating fleet. Our results also highlight the importance of assessing and monitoring vehicle emissions to develop effective air pollution control strategies. Research Implications: The information obtained in this study is unprecedented for the study area, and can therefore support the formulation of environmental policies aimed at reducing emissions of atmospheric pollutants in the state of Pará, thus promoting an improvement in air quality and public health. Originality/Value: This paper makes an unprecedented contribution to national and international literature on environmental pollution in large urban centers. On the eve of the largest climate and environment conference on the planet (COP30) to be held in Pará, Amazonas, this research joins efforts in relation to the monitoring, forecasting and mitigation of air pollution, considered one of the main environmental problems of today.

Contribution and challenges of private investment in the revitalization of Jijel's Colonial Center (Algeria)

The rapid urbanization in Algeria, driven by substantial demographic growth and rural migration, has resulted in the neglect of historic city centers in favor of suburban areas. However, since the 2000s, a growing awareness has prompted urban revitalization and building renovation initiatives, primarily in major cities like Algiers, Oran, and Constantine. Meanwhile, older districts in small and medium-sized towns have been left to deteriorate, lacking appropriate renovation projects. Urban management authorities tend to enforce regulations without adopting a holistic approach to urban planning. In Jijel, a town located in northeastern Algeria, a specific colonial center has experienced rapid deterioration, despite its relatively young age, due to unique circumstances. The limited involvement of the public sector has paved the way for private investment. Property developers have played a pivotal role in the renovation, focusing on collective housing projects complemented by ground-floor commercial spaces. This study aims to analyze the role and impact of private investment on the colonial center, with a specific focus on the exclusivity of this investment and its effects on attractiveness and revitalization.

Crustal seismicity and updated stress mapping in the Bolivian Orocline, Central Andes

The Central Andes region, with significant seismic activity, has distinct faulting mechanisms across its varied topography. Notably, the sub-Andean province predominantly features reverse faulting, whereas the high Andean plateau shows a predominance of normal and strike-slip faults. Despite the importance of this extensive orogenic plateau, Bolivia remains under-documented in seismic studies. We used data from recently installed seismic stations in Bolivia and regional stations in Brazil to determine 13 new focal mechanisms of shallow crustal earthquakes in Bolivia, some of them felt in major cities. Employing probabilistic full waveform moment tensor inversion and P-wave polarities, we mapped the stress distribution across the Central Andes. The main patterns of faulting mechanisms were: reverse faulting along the NW-SE trending sub-Andean belt north of the Orocline (north of Cochabamba) with NE-SW compression; reverse faulting along the N-S trending sub-Andean belt south of the Orocline (south of Santa Cruz) with ∼ E-W oriented compression; strike-slip faulting within the Eastern Cordillera with NE-SW P axes. The results indicate that the sub-Andean belt experiences compressional forces perpendicular to the front of the Andean plateau, arising from both the spreading stresses of the plateau and the broader plate-wide compression. On the other hand, the high plateau (Altiplano) is characterized by normal and strike-slip mechanisms, suggesting a dynamic equilibrium between local extensional gravitational stresses and regional compressional forces due to the Nazca plate convergence.

Ethnic Identity and Violence in Urban Spaces: Looking Through the Lens of ‘Cultural Conditioning’

In the recent past, the episodes of violence against the Northeast migrants in major metropolitan cities have raised debates on the racial nature of such violence and have drawn scholarly attention. This article maps the experiences of differential treatment and violence among the Northeast migrants in the national capital city and looks into the consequences of such experiences and strategies to cope with various challenges in daily life. It critically examines the experiences through the sociocultural dynamics of the local societies within the city where the ethnic migrants live. It considers the experiential accounts of a sample of 130 Northeast migrants from different urban local cultures in the national capital of India. Data on lived experiences and various perspectives of the Northeast migrants are collected using a mixed-method approach. The article reveals that ethnic identity plays a role in everyday experiences with some sorts of disadvantages. The ‘construction of otherness’ is found to have a disproportionate impact on their day-to-day life. However, there have been perceived positive changes in the ‘perceptual distance’ and inter-group behaviours. Given that most of the experiences of differential treatment and violence among Northeast migrants are located within the context of the local societies in the city and they have everyday encounters for social acceptance, the article argues that the inter-group relationships are exceedingly shaped by the sociocultural orientations of the people in local societies. The article asserts that understanding the violence against a migrant ethnic minority in cosmopolitan cities cannot undermine the role of social and cultural boundaries of urban local societies.

Research on the Mechanism of Digital Economys Impact on Regional Industrial Structure Upgrading: A Case Study of Shenzhen

The digital economy, as an integrated economy, has become the driving force behind economic growth in various regions, fueling economic transformation and upgrading and serving as the focal point of industrial competition.

By exploring the mechanisms through which the digital economy impacts the upgrading of regional industrial structures, this paper analyzes how the digital economy promotes regional industrial transformation and upgrading through technological innovation, industrial integration, and market competition. It also discusses the existing problems and challenges, and proposes corresponding policy recommendations in areas such as talent cultivation, improving social welfare, and supporting enterprises to better leverage the role of the digital economy in upgrading the regional industrial structure. These efforts aim to ensure the sustainable development of Shenzhens economy, making the new engine more powerful in leading development, creating jobs, supporting international competition, and driving Shenzhens economic and social progress toward high quality.

Exploring impacts of electricity tariff on charging infrastructure planning: An activity-based approach

In the past decade, electric vehicles (EVs) have gained popularity for their efficiency and environmental benefits. Advances in battery technology and charging equipment have yielded long-range EVs and fast-charging. However, many major cities lack adequate charging infrastructure for daily EV use. This study addresses this gap by integrating activity-based modeling, charging behavior simulation, and charging infrastructure optimization. The research utilizes the POLARIS agent-based transportation model to accurately capture user activities, trip patterns, and traffic flows. Additionally, the study investigates the impact of fixed and spatiotemporal electricity rate distributions on optimal charging infrastructure deployment. The framework is applied to the Chicago regional area network and analyzed under various EV ownership scenarios. The results reveal significant impacts of the charging pricing strategy on user decision-making and charging demand distribution. There is also a need for consistent pricing policies in charging infrastructure planning and operational phases to avoid drops in service quality.

Sustainable management of construction and demolition waste in Bangladesh to promote resource recycling

ABSTRACT This study conducted during the fiscal year of 2022–2023 endeavors to offer waste generation rates (WGR) for different Construction and Demolition Waste (CDW) materials and analyze the financial and environmental benefits of CDW recycling at a national level. Findings from the study reveal that CDW in Bangladesh mainly consists of concrete (56%), brick (15%), mortar (9%), metal (6%), and ceramics (6%). Additionally, the collective CDW produced in six major cities studied totals 3.71 million tons (MT). The WGR of CDW is assessed through regression analysis. The mean WGR for Construction and Demolition activities in the fiscal year 2022–2023 are notably recorded at 64.68 kg/m2 and 1626.97 kg/m2, correspondingly for the 12 city corporations. The study highlights the potential for entrepreneurial initiatives in recycling materials like concrete, brick, mortar, metal, ceramics, and timber, leading to reduced CO2 emissions and energy consumption. The estimated economic value of recycling concrete, brick, and metals in major cities is approximately 104.5 million USD and 0.45 MT of CO2 reduction from recycling brick and metals from major cities.

Pengaruh Literasi Keuangan Syariah terhadap Keputusan Nasabah dalam Memilih Cicilan Kendaraan Islami

This study aims to analyze the influence of Islamic financial literacy on customer decisions in choosing Islamic vehicle installments in Indonesia. Using a quantitative approach, a survey was conducted on several respondents in five major cities in Indonesia. The results showed that the level of Islamic financial literacy has a significant positive influence on customer preferences for choosing Islamic vehicle installments. Logistic regression analysis revealed that every one-point increase in the Islamic financial literacy score increases the odds of choosing Islamic vehicle installments by 4.9%. Demographic factors such as age, education, and income also have a significant influence. These findings highlight the importance of efforts to improve Islamic financial literacy as a strategy to encourage the adoption of Islamic financing products. Practical implications include the need for targeted education programs, improved product communication, and innovation in the development of competitive Islamic financing products.

A pilot study of thecardiopulmonary effects in healthy volunteers after exposure to high levels of PM2.5 in a New York City subway station.

Subway systems are becoming increasingly common worldwide transporting large populations in major cities. PM2.5 concentrations have been demonstrated to be exceptionally high when underground, however. Studies on the impact of subway PM exposure on cardiopulmonary health in the United States are limited. Healthy volunteers in New York City were exposed to a 2-h visit on the 9th Street Station platform on the Port Authority Trans-Hudson train system. Blood pressure, heart rate variability (HRV), spirometry, and forced impulse oscillometry were measured, and urine, blood spot, and nasal swab biosamples were collected for cytokine analysis at the end of the 2-h exposure period. These endpoints were compared against individual control measurements collected after 2-h in a "clean" control space. In addition to paired comparisons, mixed effects models with subject as a random effect were employed to investigate the effect of the PM2.5 concentrations and visit type (i.e., subway vs. control). Mean PM2.5 concentrations on the platform and during the control visit were 293.6 ± 65.7 (SD) and 4.6 ± 1.9µg/m3, respectively. There was no change in any of the health metrics, but there was a non-significant trend for SDNN to be lower after subway exposure compared to control exposure. Total symptomatic scores did increase post-subway exposure compared to reported values prior to exposure or after the control visit. No significant changes in cytokine concentrations in any specimen type were observed. Mixed-effects models mostly corroborated these paired comparisons. Acute exposures to PM on a subway platform do not cause measurable cardiopulmonary effects apart from reductions in HRV and increases in symptoms in healthy volunteers. These findings match other studies that found little to no changes in lung function and blood pressure after exposure in underground subway stations. Future work should still target potentially more vulnerable populations, such as individuals with asthma or those who spend increased time underground on the subway such as transit workers.

Air Pollution and Urban Economic Growth: A Study Based on Dynamic Models

&lt;p class="Paragraph"&gt;&lt;span lang="EN-US"&gt;With China's economic growth, the issue of air pollution has become increasingly prominent. As the core of political and economic development, 184 major cities in China face severe air pollution and significant environmental pressures due to high population density. Consequently, China has established key urban environmental monitoring stations in these cities to monitor pollution emissions in real time. This paper utilizes panel data from 184 Chinese cities spanning 2012-2022 and employs dynamic GMM models, fixed effects models, and mediation effect models to empirically examine the impact of air pollution on urban environmental pollution and its mediation mechanisms. From the perspective of cities with different income levels, a dynamic GMM model is established to determine the correlation between air pollution and various factors influencing urban economic growth. The study finds that air pollution significantly reduces economic growth in Chinese cities at the 1 per cent level, with each unit increase in air pollution reducing economic growth in Chinese cities by 0.84 units. Urbanization and human capital are identified as two crucial channels through which air pollution affects the economic development of Chinese cities. The negative impact of air pollution on economic growth is more pronounced in larger cities compared to smaller ones, and the adverse effects of haze pollution become increasingly significant over time. Therefore, policymakers should take the cultivation and application of new quality productivity as a key strategy to enhance the quality of economic development, and realise a win-win situation between economic growth and environmental protection through scientific and technological innovation and industrial restructuring. This will not only help alleviate the air pollution problem, but also inject new momentum into the high-quality development of China’s economy.&lt;/span&gt;&lt;/p&gt;

Gentrification creates social class disparities in belonging.

Gentrification impacts nearly every major city in the United States, posing a potential threat to lower social class residents' sense of belonging in their neighborhoods. In one survey and three preregistered experiments, we investigated how gentrification affects the belonging of residents across the social class spectrum and how to invest in working-class neighborhoods without undermining lower social class residents' sense of belonging. Studies 1-3 (Ns = 141, 1,085, and 510, respectively) provided correlational and experimental evidence that lower social class residents feel less belonging than higher social class residents in gentrifying neighborhoods. Study 3 showed that this belonging disparity was mediated by lower social class individuals perceiving themselves to be less similar to and less trusting of other residents and higher social class individuals feeling the amenities would better suit them in the gentrifying neighborhood. Nevertheless, neighborhood investment does not always threaten lower social class individuals' sense of belonging. Study 4 (N = 402) showed that lower social class individuals anticipated greater belonging and were more supportive when neighborhood investment was community driven (i.e., prioritized the needs of existing residents) than capital driven (i.e., prioritized economic growth). We discuss implications for equitable urban policy and future directions for a social psychology of gentrification. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Assessment of local diagnostic reference levels (LDRLS) for full-field digital mammography (FFDM) and digital breast tomosynthesis (DBT) mammography in Tamil Nadu, India.

The purpose of this study was to assess local diagnostic reference levels (LDRLs) for full-field digital mammography (FFDM) and digital breast tomosynthesis (DBT) mammography in India. Data from 1500 women were collected from five different mammography facilities in major cities in Tamil Nadu, India. The mean of mean glandular dose were used to arrive at an LDRL. The noted mean compressed breast thickness was 55.26±3.4. The recorded mean MGDs for the five centres were 3.1±0.1 and 3.8±0.2mGy for FFDM and DBT, respectively. The 75th percentile value for all five centers is 3.3 and 4.0mGy for FFDM and DBT, respectively. The LDRLs found in the current study were also compared with those from earlier studies conducted in other nations, such as the United Kingdom, Malaysia, Morocco, and Ghana. The present study is the first of its kind to determine the LDRL for the FFDM and DBT scanners operating in the Tamil Nadu region, India, and is proposed as a starting point that will allow professionals to evaluate and optimize their practice. Furthermore, similar studies in other regions of India are necessary in order to establish National DRLs.

Simultaneous comparison of the chemical composition and attributable source of PM2.5 during 2014–2018 in major metropolitan cities in South Korea: impacts of policy interventions

Abstract Ambient fine particulate matter (PM2.5) is one of the most concerning pollutants, characterized by its diverse chemical composition. Although various studies have revealed PM2.5 chemical components, there is limited knowledge on how to reduce PM2.5 concentrations through administrative policies focusing on source management. We compared PM2.5 compositional characteristics and performed source apportionment using the positive matrix factorization in four metropolitan cities (Seoul, Daejeon, Gwangju, and Ulsan) in South Korea from 2014 to 2018. The annual average of PM2.5 concentrations exceeded the annual national ambient air quality standard of 15 μg m−3 in all areas while secondary inorganic aerosols constituted the largest fraction of PM2.5. This implies that secondary formation from gaseous precursors in the atmosphere was the main factor contributing to ambient PM2.5. However, the concentrations of PM2.5 constituents varied significantly across cities, suggesting that PM2.5 is a heterogeneous pollutant considerably influenced by region-specific conditions. In line with the chemical composition, secondary nitrate, secondary sulfate, and mobile-related sources were found to be significant contributors of PM2.5. Additionally, the extent of contribution from each source varied across the study regions. We also evaluated the impacts of policy interventions by comparing the PM2.5 composition and source apportionment before and after the policies for improving air quality. Intensive programs focused on the vehicle sector in Seoul led to a considerable decrease in the concentrations of carbonaceous compounds and mobile-related sources. In addition, strengthened regulations on coal-fired power plants (CFPPs) since 2016 have influenced the contributions of coal combustion sources in two cities adjacent to the west coastal area, where approximately half of the CFPPs of the country are densely distributed. Overall, the study’s findings indicate that region-specific PM2.5 chemical constituents and source contributions should be considered for establishing PM2.5-related policies, considering the high heterogeneity of PM2.5.

Determinants of Bank Selection: A Study on Consumer Perceptions and Expectations in Albania

This study investigates the factors influencing consumer perception in selecting banking services, focusing on service quality, customer satisfaction, and brand reputation within the Albanian banking sector. Using a structured questionnaire, 213 valid responses were gathered from customers in major cities, including Durres and Tirana. The analysis involved factor analysis, reliability testing, and regression analysis to explore the relationships between the identified factors and consumer decision-making. The findings reveal that service quality, encompassing tangibles, reliability, responsiveness, assurance, and empathy, plays a critical role in shaping consumer perceptions, with assurance, reliability, and responsiveness having the most significant impact. Additionally, customer satisfaction and the bank's brand influenced the selection process significantly. The results underscore the importance of banks enhancing service quality and maintaining a strong brand reputation to attract and retain customers in a competitive market. These insights provide valuable implications for bank marketers and strategists aiming to develop effective customer-centric approaches.

Noise monitoring of loud vehicles in four Dutch cities

Excessive noise from loud cars, motorcycles, mopeds, trikes and quads is commonplace in Dutch cities and is a major source of annoyance. In order to assess the sources, causes and potential solutions, TNO has performed a series of noise monitoring campaigns in four major cities including vehicle identification. Sound and vehicle data was acquired at 3 locations in each city for a period of five days. Several steps were applied to separate vehicle noise from other noises, and to attribute the noise to the correct vehicles. The resulting analysis provided insight into the types of vehicles and driving conditions causing most noise. A set of characteristic driving conditions were derived from the measurement data, including high acceleration, engine revving, engine backfire, high engine speed and others. Besides driving behaviour, vehicle modifications such as louder exhausts, removed dB-killers and mechanical or electronic engine modifications are common causes of high noise levels. Also an overview of suggested mitigation options and future outlook is given, based on the findings of the analysis.

Narrowing down the drivers of flood risk in medium-sized sub-Saharan African cities: insights from the Greater Kumasi Metropolitan Area, Ghana

ABSTRACT Literature on the drivers of flooding in sub-Saharan Africa is mostly focused on large and megacities, despite the majority of cities in the region being medium- and small-sized. We conducted a systematic review using 27 peer-reviewed scientific papers selected following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocols using the Greater Kumasi Metropolitan Area (GKMA), Ghana, as a case study, and validated the results in a workshop attended by 51 stakeholders. We found that the reported drivers of flood risk in GKMA are land cover changes (61.5%) (e.g. wetlands degradation); governance challenges (16.2%); challenges with drainage (13%); extreme rainfall (6.5%); and apathy towards nature (3.2%). We conclude that floods in GKMA are overwhelmingly human induced through unsustainable urbanization processes that are so rapid that city authorities are unable to properly control them. Also, a holistic understanding of flood risk is missing since majority of the included papers rather used qualitative methodologies.

The vowel space of multiethnolectal (Stuttgart) German.

The emergence of multiethnolects, i.e.specific speaking styles or varieties associated with second and third generation speakers from immigrant backgrounds, has been observed and studied in several major cities in Europe and elsewhere in theworld. The multiethnolect that is the focus of this study is one such variety of colloquial German. Most previous research on multiethnolectal German has focused on grammatical features. This paper reports on the first comprehensive study of the vowel system (vowel quality and global vowel space size) of multiethnolectal German, based on data from Stuttgart. The results show that the vowel space of multiethnolectal speakers is in generally more centralized than that of a comparison group. A more detailed analysis reveals that the linguistic background plays an important role, as speakers with a Turkish or South Slavonic language background are responsible for this effect.

Pixels to Paychecks: Understanding The Determinant of Latent Entrepreneurial Transition in Digital Context

In the ever-changing landscape of China’s digital economy, comprehending the transition drivers from latent to active participation in entrepreneurship is critical. This research explores the factors shaping the decisions of latent entrepreneurs to become active entrepreneurs in a digital context. Using simple random sampling, this study randomly selected 18 industries within China’s major cities. This study collected cross-sectional data from 485 respondents in high-tech and low-tech industries across six major Chinese cities and tested the model using partial least structural equation modeling (PLS-SEM). Statistical findings conducted by SmartPLS reveal a nuanced interplay between personal factors and external traits in shaping the transition to active entrepreneurship. In particular, entrepreneurial competence, digital skills and literacy, and adaptability are crucial personal factors influencing this transition. Access to the necessary technology, startup cost, market and customer base, and government support are external traits found to significantly shape individual decisions to venture into digital entrepreneurship. Surprisingly, Logistics and Transportation (LAT) had no substantial impact on the transformation. This investigation strengthens entrepreneurship theory while also providing policymakers and industry actors with practical insights. Personalized training for entrepreneurs, spending on digital infrastructure, evidence-based regulations, and enhanced business innovation initiatives are among the recommendations.
