Impact of the Built Environment on Ageing in Place: A Systematic Overview of Reviews

Background: As the global demographic shifts towards an ageing population, the significance of the built environment in facilitating ageing in place gains prominence. This study addresses the critical question of how a built environment can support older adults’ independence and enhance their quality of life. Method: Utilising a systematic review of review papers, this research scrutinises existing literature to uncover the influence of urban planning, physical accessibility, and residential design on the older people’s physical and mental well-being. More specially, the study methodically examines existing review articles that span various aspects of the built environment related to ageing in place. Results: The analysis reveals that specific elements of the built environment, notably rational urban planning and accessible urban spaces, as well as adaptable housing designs, significantly impact ageing individuals’ health, social engagement, and overall satisfaction with life. It also identifies contradictions in the effects of environmental features on cognitive health and well-being, underscoring areas that warrant further exploration. Conclusions: The study concludes that thoughtful urban and housing designs are pivotal in creating age-friendly environments that support ageing in place. It emphasises the need for future research and policy development aimed at enhancing the living conditions of older adults within their communities.

Invasive peacock basses (Cichla spp.) and decreased abundance of small native fish in Brazilian reservoirs

Abstract Peacock basses (Cichla spp.) have been introduced in impoundments for decades, and their negative impacts on the native fish fauna have been documented. However, previous studies largely focused on the overall responses of fish assemblages, often neglecting specific predator–prey interactions and the underlying effects of environmental characteristics. Here, the effects of peacock bass introduction on the size structure (<120, 120–180 and >180 mm in total length) of fish assemblages in reservoirs of the Paraíba do Sul river basin were assessed. The abundance and time since the introduction of peacock basses were used as predictors, together with reservoir features, limnological variables and habitat composition as potential influencing factors. Descriptors of the overall community (richness, abundance and species composition) were only marginally associated with the occurrence of peacock basses. However, small and (to a lesser extent) medium‐sized fish were adversely affected by the abundance and introduction time of peacock basses. Two pelagic native characids – namely Astyanax cf. bimaculatus and Oligosarcus hepsetus – were the most affected. Redundancy analysis showed that reservoir age and macrophyte cover were the best predictors of fish assemblage composition. Older reservoirs and reservoirs with a higher cover of macrophytes showed a greater abundance of catfish and characids, respectively. Peacock basses appear to affect fish assemblages through predation on small fish. Therefore, analyses of assemblages by size are recommended, as the use of overall assemblage descriptors may not be sufficient to capture the adverse effects of peacock basses. Moreover, these findings underscore the importance of conserving and restoring habitats in littoral zones, which function as refuges for native fish species in reservoirs. Further educational and management measures are warranted to prevent the spread of peacock basses to other reservoirs in Brazil.

Evaluation of the effects of urbanization and environmental features on sandy beach macrobenthos highlights the importance of submerged zones

To assess how sandy beach biodiversity is influenced by the effects of environmental features and urbanization, we sampled the macrofauna in the whole across-shore gradient of 90 beach sites in Southeast Brazil. We found that morphodynamic features were the main drivers of macrobenthos, but urbanization-related variables, such as number of beachgoers and number of constructions on the upper shore, decreased species richness and biomass. We also found that submerged zones sustained the highest number of species and biomass in the across-shore gradient, but were the most impacted by human activities. By demonstrating the ecological importance of submerged zones, our results show that beach management practices, which are mainly focused on the upper shore, are missing important components of beach biodiversity. To secure the sustainability of beach ecosystems, management initiatives should include both their social and ecological components and consider the entire Littoral Active Zone as the proper management unit.

Density Dependence and Adult Survival Drive Dynamics in Two High Elevation Amphibian Populations

Amphibian conservation has progressed from the identification of declines to mitigation, but efforts are hampered by the lack of nuanced information about the effects of environmental characteristics and stressors on mechanistic processes of population regulation. Challenges include a paucity of long-term data and scant information about the relative roles of extrinsic (e.g., weather) and intrinsic (e.g., density dependence) factors. We used a Bayesian formulation of an open population capture-recapture model and >30 years of data to examine intrinsic and extrinsic factors regulating two adult boreal chorus frogs (Pseudacris maculata) populations. We modelled population growth rate and apparent survival directly, assessed their temporal variability, and derived estimates of recruitment. Populations were relatively stable (geometric mean population growth rate >1) and regulated by negative density dependence (i.e., higher population sizes reduced population growth rate). In the smaller population, density dependence also acted on adult survival. In the larger population, higher population growth was associated with warmer autumns. Survival estimates ranged from 0.30–0.87, per-capita recruitment was <1 in most years, and mean seniority probability was >0.50, suggesting adult survival is more important to population growth than recruitment. Our analysis indicates density dependence is a primary driver of population dynamics for P. maculata adults.

Effects of environmental characteristics and business partner relationships on improving innovation performance through the mediation of knowledge management practices

PurposeThis study aims to know the effects of environmental characteristics and business partner relationships on improving innovation performance through the mediation of knowledge management practices (KMPs).Design/methodology/approachThe population of this research was all manufacturing companies engaged in the food and beverage sector categorized into large industries. According to Jakarta’s Badan Penyelenggara Jaminan Sosial (BPJS) Ketenagakerjaan (social insurance administration body of employment), large industries are industries with a number of employees > 100. However, in this research, the total population did not reach 100 but only 89 companies. The analysis unit used in this research was the companies. Data collection for this research relied on questionnaires with closed questions. The questionnaires were then distributed to the sample companies by using enumerator services. In accordance with the hypotheses formulated, the data analysis used in this research was partial least square.FindingsThe three findings are the significant and negative effect of environmental characteristics on KMPs, the significant effect of business partner relationships on innovation performance and the insignificant effect of KMPs on innovation performance. The management of food sector manufacturing companies needs to support the activities of generating ideas carried out by employees and support their innovative ideas and creativity. Good cooperation between employees and management is highly needed in an effort to develop company innovation.Originality/valueThis research used the innovation diffusion paradigm and the combination of market-based and knowledge-based paradigms is expected to fill the previous research gap and become the uniqueness and originality of this research. The second originality is that this research examined the role of the KMP variable as the moderating variable. The third originality of this research is the focus on examining the effect of business partner relationships on innovation performance. These three originalities are rarely found in previous studies. Therefore, this research is expected to complete and expand the study of knowledge management and innovation performance.

Diurnal and Seasonal Variations in the Effect of Urban Environmental Factors on Air Temperature: A Consecutive Regression Analysis Approach.

This study investigates the diurnal and seasonal variations in the effect of environmental features on air temperature in Seoul, Korea. We expect that this study will lead to the identification of factors that can be applied for urban heat island mitigation strategies in summer without leading to an unintended result in winter. As our dependent variable, we employed the smoothed 31-day moving average of air temperatures, where we controlled the seasonal variation by normalizing the values observed from 247 automatic weather stations (AWS) from 2015 to 2016. Subsequently, we conducted consecutive log–log regression analyses of each day to examine patterns of change in regression coefficients and the significance of each independent variable. For independent variables, we applied built environment features including albedo, land-use, average building floors, the sky view factor, and green and water areas. This study provides analytical results regarding the relationship between environmental factors and air temperature. This study also addresses imperative issues for planners, especially regarding albedo, wind path, building geometry, and land use types. Finally, this study gives useful insights for managing the diurnal and seasonal variations of urban thermal environment in the mega-city.

Developing openly accessible health indicators for small areas in Great Britain: an observational study

BackgroundPublic health has long been concerned with understanding how the accessibility of individuals to certain environmental features can influence health and wellbeing. Such insights are increasingly being adopted by policy makers for designing healthy neighbourhoods. We aimed to use small area national level data to support and inform decision making about effects of environmental features on health. MethodsMeasures were selected by a scoping review of geographical determinants of health. Road network distance for every postcode centroid in Great Britain to its nearest outlet postcode centroid (for ten retail and health-related services) was calculated. These results were aggregated to lower super output areas. We also created measures of green space (amount of green space within a 900 m2 buffer) and concentrations of air pollutants (nitrogen dioxide, sulphur dioxide, and particulate matter less than 10 μm in diameter). Data were validated through field observations. An index (Access to Healthy Assets and Hazards) was also developed to summarise all the indicators into an overall measure of how healthy neighbourhoods are. Outcomes were point estimates of distance to nearest service, or level of green space or air pollution, and an overall score summarising these values for the index. FindingsIndividuals were located nearest to health services (eg, median distance to a general practice was 1·05 km, IQR 0·65–1·79), although they were just as near to many health negating outlets (eg, pubs 1·12, 0·64–1·99). Wide social inequalities were observed; for example, mean distance to a fast food outlet in the most deprived decile of areas in England was 1·17 km (95% CI 1·17–1·22) compared with 2·42 (2·35–2·49) in the least deprived decile. Access to Healthy Assets and Hazards identified suburban regions as the healthiest environments, and inner city and isolated rural areas as the least healthy. InterpretationOur open source suite of measures offers a useful resource for understanding the accessibility of small areas to positive and negative features of environments. We extend previous approaches towards designing health-related indicators by creating a multidimensional index, which has been incorporated into Public Health England's FingerTips system.

Effect of Environmental Factors on Cyanobacteria Richness in Some Agricultural Soils

The physicochemical variations of soil, such as temperature, pH, nutrients, and the type of plant cultivation, affect the diversity of cyanobacteria, whether heterocystous or not. The aim of this study was to identify the species of cyanobacteria in a soil and the effect of environmental characteristics on cyanobacteria. Soil samples collected from six different agricultural sites in Al Diwaniyah city/Iraq during September 2016 in the autumn season were analyzed, and the physicochemical characteristics of the samples were measured using approved methods.The results showed significant correlation and differences between cyanobacteria composition, distribution, and physicochemical factors among soil sites. The Agricultural soil was slightly alkaline and moderately saline and contained abundant nutrients, cations and a high percentage of organic matter. All these characteristics influenced the distribution and diversity of cyanobacteria. Ninety-six species were identified, including four heterocystous species represented by Anabaena, Calothrix, Cylnidrospermum, and Nostoc. However, the non-heterocystous were represented by 13 species: Aphanocapsa, Aphanothece, Arthrospira, Chroococcus, Gloeocapsa, Lyngbya, Merismopedia, Microcystis, Microcoleus, Oscillatoria, Phormidium, Schizothrix, and Spirulina. The dominant species of cyanobacteria was Oscillatoria, followed by Phormidium, Chroococcus, Gleocapsa and Lyngbya. The highest value of Shannon’s and Simpson’s diversities were registered in the Ghammas site, which is a paddy field, but the lowest was registered in the Afak site, cultivated with the alfalfa plant. Soil was classified as finely textured with silty clayey characterization, favorable for cyanobacteria growth.

Offspring sex ratio and reproductive tactics of Leptocybe invasa (Hymenoptera: Eulophidae): testing the effect of environmental characteristics

AbstractEnvironmental characteristics (for example, temperature, photoperiod) as seasonal cues can affect the offspring sex ratio and reproductive tactics of many hymenopteran insects.Leptocybe invasaFisher & La Salle is the most critical invasive insect pest ofEucalyptusspp. in the world and displays thelytokous reproduction. In the current study, we studied the effects of temperature and photoperiod on offspring sex ratio and reproductive tactics inL. invasa. Results show that sex ratio (female: male) ofL. invasawas under 15, 25 and 35 °C with both L 12: D 12 and L 16: D 8, and cold and thermal acclimation were 74.5:1, 71.0:1, 59.0:0, 17.3:1, 53.0:0, 64.0:0, 47.0:1 and 56.0:0, respectively, which was highly significantly female biased and with no significant difference due to temperature or photoperiod. Offspring virgin females oviposited and induced the bump-shaped galls on plants under the same conditions as described above. Constant temperature, photoperiod and their interaction, and cold and thermal acclimation had no significant effect on the infestation rates ofEucalyptusbranches induced by offspring virgin females. Thus, temperature, photoperiod and cold and thermal acclimation did not influence female-biased sex ratio and tactics with thelytokous reproduction of offspring females inL. invasa.

Paralyzed by the Dashboard Light: Environmental Characteristics and Firm Capabilities

Firms in the East African region have been faced with highly uncertain environments, which has fueled environmental dynamism, changes in industry structures and enhanced competitive dynamics. In order to understand the opportunities and challenges within this environment, firms need to develop scanning capabilities to cope with this uncertainty. However, the effect of environmental characteristics on the development of firm capabilities in developing countries is unclear. In this paper, we analyze how different environmental characteristics drive or hamper the development of firm capabilities. We focus specifically on environmental scanning capabilities that allow firms to respond swiftly to changing needs by monitoring its environment. We include four environmental characteristics: environmental dynamism, heterogeneity, formal and informal competition. We investigate this in Kenya, Tanzania and Uganda in a sample of 473 manufacturing firms. Our main results indicate that environmental dynamism and informal competition have a paralyzing effect on the development of scanning capabilities of firms in East Africa. Thus, environmental characteristics can indeed hamper the development of firm capabilities.

The Effects of Environmental Features and Overstory Composition on the Understory Species Assemblage in Sub-Mediterranean Coppiced Woods: Implications for a Sustainable Forest Management

Understanding the relationship among environmental factors, overstory and understory is a key step for the improvement of sustainable forest management. Our aim was to understand how environmental features (topographic factors) and overstory (tree species) composition affect understory (shrub and herb species) assemblage in sub-Mediterranean coppiced woods. The study area lies in the Monti Sibillini National Park (central Italy). In 205 plots (20 × 20 m) we collected topographic features and species cover values; moreover, we defined the Social Behaviour Type (SBT — i.e. species ecological and dynamic features) of each understory species. Data were analysed using Redundancy Analysis and Generalized Linear Modeling. We found that topographic factors shaped percentage cover of different tree species and hence determined forest community type. Topography-related factors were further mediated by the tree layer composition, in filtering understory assemblage, on the basis of species SBT. We found no effect of overstory species diversity on understory species diversity. However, the presence of tree species different from the dominant ones increased understory species richness. This effect was particularly notable in evergreen woods, dominated by Quercus ilex. We conclude that, to improve the management sustainability, coppicing management should be focused on the achievement of the greater tree species diversity.

Risk and safety perception on urban and rural roads: Effects of environmental features, driver age and risk sensitivity

ABSTRACTObjective: The ability to detect changing visual information is a vital component of safe driving. In addition to detecting changing visual information, drivers must also interpret its relevance to safety. Environmental changes considered to have high safety relevance will likely demand greater attention and more timely responses than those considered to have lower safety relevance. The aim of this study was to explore factors that are likely to influence perceptions of risk and safety regarding changing visual information in the driving environment. Factors explored were the environment in which the change occurs (i.e., urban vs. rural), the type of object that changes, and the driver's age, experience, and risk sensitivity.Methods: Sixty-three licensed drivers aged 18–70 years completed a hazard rating task, which required them to rate the perceived hazardousness of changing specific elements within urban and rural driving environments. Three attributes of potential hazards were systematically manipulated: the environment (urban, rural); the type of object changed (road sign, car, motorcycle, pedestrian, traffic light, animal, tree); and its inherent safety risk (low risk, high risk). Inherent safety risk was manipulated by either varying the object's placement, on/near or away from the road, or altering an infrastructure element that would require a change to driver behavior. Participants also completed two driving-related risk perception tasks, rating their relative crash risk and perceived risk of aberrant driving behaviors.Results: Driver age was not significantly associated with hazard ratings, but individual differences in perceived risk of aberrant driving behaviors predicted hazard ratings, suggesting that general driving-related risk sensitivity plays a strong role in safety perception. In both urban and rural scenes, there were significant associations between hazard ratings and inherent safety risk, with low-risk changes perceived as consistently less hazardous than high-risk impact changes; however, the effect was larger for urban environments. There were also effects of object type, with certain objects rated as consistently more safety relevant. In urban scenes, changes involving pedestrians were rated significantly more hazardous than all other objects, and in rural scenes, changes involving animals were rated as significantly more hazardous. Notably, hazard ratings were found to be higher in urban compared with rural driving environments, even when changes were matched between environments.Conclusion: This study demonstrates that drivers perceive rural roads as less risky than urban roads, even when similar scenarios occur in both environments. Age did not affect hazard ratings. Instead, the findings suggest that the assessment of risk posed by hazards is influenced more by individual differences in risk sensitivity. This highlights the need for driver education to account for appraisal of hazards’ risk and relevance, in addition to hazard detection, when considering factors that promote road safety.

Effects of environmental features and sport hunting on caribou migration in northwestern Alaska

BackgroundUngulate movements are influenced by a variety of biotic and abiotic factors, which may affect connectivity between key resource areas and seasonal ranges. In northwestern Alaska, one important question regarding human impacts on ungulate movement involves caribou (Rangifer tarandus) response to autumn hunting and related aircraft activity. While concerns have been voiced by local hunters about the influence of transporter aircraft and non-local sport hunters, there has been little quantitative analysis of the effects of hunter activity on caribou movement. We utilized a novel spatial dataset of commercial aircraft landing locations and sport hunter camps in and around Noatak National Preserve to analyze resource selection of caribou in autumn for non-local hunting activity and environmental features. We combined step selection functions with randomized shortest paths to investigate whether terrain ruggedness, river width, land cover, and hunting activity (in the form of aircraft landings and sport hunter camps) facilitated or impeded caribou movement. By varying a parameter in the randomized shortest path models, we also explored the tradeoff between exploration and exploitation in movement behavior exhibited by traveling caribou.ResultsWe found that caribou avoided rugged terrain and areas with more river, forest, and tall shrubs while selecting for areas dominated by tussock tundra and dwarf shrubs. Migration of caribou through Noatak does not appear to be inhibited by sport hunting activity, though this does not preclude the possibility of temporary effects altering availability of caribou for individual hunters. Caribou exhibited exploratory movement, following predictions of a random walk model. This behavior may facilitate the location of remaining patches of high-quality forage prior to the onset of winter, especially during mild autumns.ConclusionsUnderstanding animal movement behavior is fundamental to protecting critical areas of connectivity and to informing management decisions. Our study identifies migratory connectivity and hotspots of potential conflict among user groups, enabling development of policies that balance human access with species conservation.

The Effect of Environmental Features, Self-Avatar, and Immersion on Object Location Memory in Virtual Environments

One potential application for virtual environments (VEs) is the training of spatial knowledge. A critical question is what features the VE should have in order to facilitate this training. Previous research has shown that people rely on environmental features, such as sockets and wall decorations, when learning object locations. The aim of this study is to explore the effect of varied environmental feature fidelity of VEs, the use of self-avatars and the level of immersion on object location learning and recall. Following a between-subjects experimental design, participants were asked to learn the location of three identical objects by navigating one of three environments: a physical laboratory, or low and high detail VE replicas of this laboratory. Participants who experienced the VEs could use either a head-mounted display (HMD) or a desktop computer. Half of the participants learning in the HMD and desktop systems were assigned a virtual body. Participants were then asked to place physical versions of the three objects in the physical laboratory in the same configuration. We tracked participant movement, measured object placement, and administered a questionnaire related to aspects of the experience. HMD learning resulted in statistically significant higher performance than desktop learning. Results indicate that, when learning in low detail VEs, there is no difference in performance between participants using HMD and desktop systems. Overall, providing the participant with a virtual body had a negative impact on performance. Preliminary inspection of navigation data indicates that spatial learning strategies are different in systems with varying levels of immersion.

Seasonal population changes in the ammonia-oxidizing bacteria community structure of Songhua Lake, China

Abstract Ammonia-oxidizing bacteria (AOB) and the effects of environmental characteristics on the AOB community distribution were investigated in the Songhua Lake in May, August, October and December of 2011. Profiles of the AOB communities were generated using denaturing gradient gel electrophoresis (DGGE) to assess the expression of 16S rRNA genes followed by DNA sequence analysis. The dominant AOB groups were affiliated with Nitrosomonas and Nitrosospira spp. The effects of environmental characteristics on the AOB community distribution were analyzed by the ordination technique of redundancy analysis. The environmental characteristics significantly influencing the AOB community structure were different in the four seasons. The suspended solids (SS), ammonia nitrogen (NH 4 + -N) and nitrate nitrogen (NO 3 − -N) differed in May, the pH, NH 4 + -N, NO 3 − -N and total nitrogen (TN) differed in August, and the NH 4 + -N, DO and TN differed in December. None of the assessed environmental variables displayed heterogeneity in October. This study suggested that seasonal variation and nutrient differences might be responsible for the differences in the key environmental characteristics used to determine the distribution of the AOB communities in all seasons.

Diversity in the monotony? Habitat traits and management practices shape avian communities in intensive vineyards

Spreading of viticulture may pose serious threats to biodiversity and adequate policies targeted at decreasing its impact are urgently required. Current knowledge of viticulture effects on biodiversity is scarce and studies on bird communities in vineyards are even scarcer.We surveyed avian assemblages in Trentino vineyards (North-East Italy) in both breeding and wintering seasons to evaluate the effect of: i) landscape, ii) management and iii) topographic-climatic characteristics on birds and to derive implications for conservation. We calculated four community indexes (species richness, abundance, evenness and conservation index) and modelled their relative variation according to 18 environmental variables belonging to the three above-mentioned groups.Landscape models performed better than the others, except for winter evenness, for which management models were the most supported ones. Generally, models considering the three groups together explained more variation than models from an individual group.Landscape (and agricultural) heterogeneity, extent of marginal habitats, density of traditional elements (hedgerows, tree rows, isolated trees and rural buildings) all had positive effects, whereas vineyard cover had negative impact on the value of the four community indexes.Organic management had no apparent effect on avian communities. We detected a seasonal difference in the effects of environmental characteristics on bird communities, which suggested that local conservation efforts could be tuned according to the seasonal importance of vineyards in different regions.Key measures to promote biodiversity in vineyards include maintaining patches of residual habitats in the vineyard matrix and enhancing heterogeneity. Marginal features appeared particularly important in the homogeneous landscape of intensive vineyards to favour bird communities.

Factors influencing the formation of shallow landslides in the Boston Mountains of northwest Arkansas, USA

Slope failures cause billions of dollars of damage annually and put human lives at risk. This study employed field measurements and observations to provide the framework for laboratory simulations to investigate the effects of environmental characteristics on slope stability in the highly fractured bedrock region of the Boston Mountains, northwest Arkansas. Field measurements, to determine characteristics and possible controls of 10 shallow slope failures along an interstate highway, revealed that slope failures occurred within a relatively narrow range of slope angles (17–36°) and in loamy soils. Based on field observations, flume experiments were conducted to investigate the relationships between soil texture, slope angle, bedrock fractures, soil compaction, and slope instability. Time to failure differed (p < 0.05) among treatment combinations. Generally, slopes composed of loam were more stable than slopes composed of sand. Time to failure decreased more on slopes of 15–20° than on slopes of 20–25°. Flume slopes with sod cover never failed. This study provided a methodology for using field analyses of slope failures to guide laboratory experiments and demonstrated that complex interactions among environmental factors work to stabilize or compromise steep (>20°) slopes.

Environmental drivers of macrophyte species richness in artificial and natural aquatic water bodies – comparative approach from two central European regions

Species richness of macrophytes of artificial and natural water bodies covering rivers, streams, canals and habitats with standing water was studied in two Central European biogeographical regions, Pannonian and Carpathian, represented by two model areas (the Borská nížina Lowland and the Turčianska Kotlina Basin). We found that: (i) the total number of macrophytes was higher in artificial water bodies compared to natural aquatic habitats in both regions and differences were statistically significant (P<0.05); and (ii) species richness of macrophytes is relatively low in both regions; slightly higher mean number was found in the Pannonian region (3.53) compared with the Carpathian region (3.06). Effects of environmental characteristics on species richness studied by generalized linear model (GLM) showed that explained variances of GLM were similar in both regions. The main drivers of the diversity pattern were those connected with the hydrology of water bodies, such as substrate characteristics and turbidity, less frequent were chemical characteristics, such as water conductivity and N-contents, whereas landscape characteristics manifested the smallest impact.
