Sentiment News in the Nigerian Reit Market: Source and its Dynamic Nature

In this study, we assess the source and dynamic nature of sentiment news on the Nigerian REIT market. The study adopts direct survey method and the Nigerian stockbrokers were surveyed through close-end questionnaire instrument. The data collected were analysed by weighted mean score and stepwise regression model. The result showed that the prominent source of biased news in the property stock market is pronouncements/announcements on economic indices and capital markets. The REIT market is more active, with often buying decisions during the optimistic market mood driven by good news. The pessimism market condition is characterized by the decision to sell, often dominated by pessimistic investors; the optimistic investors take caution, leading to a dull market and low return on investment. Findings also revealed that sentiment news from pronouncements/announcements significantly explains the dynamic behaviour of investors during the optimistic market condition; the media/press report significantly explains investor behaviour towards property stock in the pessimism market condition. The study concluded that the need to examine irrational behaviour attributed to sentiment news is imperative to optimal investment decisions when thinking of investment in the REIT market

Oxidative discolouration in whole-head and cut lettuce: biochemical and environmental influences on a complex phenotype and potential breeding strategies to improve shelf-life

Lettuce discolouration is a key post-harvest trait. The major enzyme controlling oxidative discolouration has long been considered to be polyphenol oxidase (PPO) however, levels of PPO and subsequent development of discolouration symptoms have not always correlated. The predominance of a latent state of the enzyme in plant tissues combined with substrate activation and contemporaneous suicide inactivation mechanisms are considered as potential explanations for this phenomenon. Leaf tissue physical properties have been associated with subsequent discolouration and these may be influenced by variation in nutrient availability, especially excess nitrogen and head maturity at harvest. Mild calcium and irrigation stress has also been associated with a reduction in subsequent discolouration, although excess irrigation has been linked to increased discolouration potentially through leaf physical properties. These environmental factors, including high temperature and UV light intensities, often have impacts on levels of phenolic compounds linking the environmental responses to the biochemistry of the PPO pathway. Breeding strategies targeting the PALand PPOpathway biochemistry and environmental response genes are discussed as a more cost-effective method of mitigating oxidative discolouration then either modified atmosphere packaging or post-harvest treatments, although current understanding of the biochemistry means that such programs are likely to be limited in nature and it is likely that they will need to be deployed alongside other methods for the foreseeable future

Density and Urban Sprawl

Along with its economic reform, China has experienced a rapid urbanization. This study mapped urban land expansion in China using high-resolution Landsat Thematic Mapper and Enhanced Thematic Mapper data of 1989/1990, 1995/1996 and 1999/2000 and analyzed ...

Accessibility, urban form, and property value: A study of Pudong, Shanghai

The effects of metro system development and urban form on housing prices highly depend on the spatial temporal conditions of urban neighborhoods. However, scholars have not yet comprehensively examined these interactions at a neighborhood-scale. This study assesses metro access, urban form, and property value at both the district- and neighborhood-level. The study area is Pudong, Shanghai, where metro system development has coincided with rapid urban growth. Two hundred and seventy-nine neighborhoods from 13 districts of Shanghai are randomly selected for the district-level investigation and 31 neighborhoods from Pudong are selected for the neighborhood-level investigation. The analysis of variance shows that metro access is more positively correlated to property price in Pudong than other districts. The Pearson correlation, principle component, and ordinary least square regression analyses show that while accessibility attributes have a positive influence on housing prices, neighborhood characteristics also exhibit a pronounced impact on property price change over time. This study extends our knowledge on how metro system development interacts with land-use efficiency and discusses planning policies that correspond to different stages of development.Guan, ChengHe; Peiser, Richard B..

Is the Pandemic Causing a Return to Urban Sprawl?

Urban sprawl is a catch-all term and a scapegoat for everything that is bad about urban growth today, such as congestion, blight, monotony, and ecological destruction. In recent decades, sprawl might have attenuated as America experienced a period of urban revival even as technology made working from home (WFH) and shopping from home possible nearly anywhere. The onset of the COVID-19 pandemic has accelerated the adoption of infrastructures and forced firms to rethink the necessity of workplaces. Retailers have accelerated the pace of online sales and home deliveries by years if not decades. These and other advances have decoupled people from their workplaces, shopping and other activities usually associated with density. Indeed, the sudden spurning of urban density attributable to the pandemic raises fundamental questions for the future of cities. While the pandemic has accelerated trends in people moving out of denser neighborhoods in metropolitan areas in favor of smaller metros, suburban, and exurban locations, the major shift in net migration is from a drop in people moving into central cities. This paper contextualizes pandemic era migration literature with prior studies of urban sprawl to derive a useful framework for planners, developers, and decision-makers to better understand how cities expand and to predict the lasting impacts that COVID-19 will leave on U.S. cities
