Urbanization is an unavoidable process of social and economic growth in modern times. However, the speed with which urbanization is taking place produces complex environmental changes. It has affected the surface albedo and roughness of the soil, thereby modulating hydrological and ecological systems, which in turn has affected regional and local climate systems. In developing countries of South Asia, rampant and unplanned urbanization has created a complex system of adverse environmental scenarios. Similar is the case in India. The state of the urban environment across India is degrading so quickly that the long-term sustainability of its cities is endangered. Many metropolitan cities in India are witnessing the harmful impacts of urbanization on their land ecology. In this context, remote sensing and geographic information system (GIS) based assessments provide a comprehensive and effective analysis of the rate and the impact of urbanization. The present study focuses on understanding the spatiotemporal characteristics of urban growth and its implications on the geomorphology of the Panchkula District, Haryana, one of the fastest-growing urban centers in India. The study links the changes in land use/land cover (LULC) with the changing geomorphology of the study area using satellite remote sensing and GIS. The results showed that between 1980 and 2020, agricultural (+73.71%), built-up (+84.66%), and forest (+4.07%) classes of land increased in contrast to that of the fallow land (−76.80%) and riverbed (−50.86%) classes that have decreased in spatial extents. It has been observed that the hill geomorphological class had decreased in the area owing to conversion to industrial and built-up activities. Assessment of the environmental quality of cities involves multiple disciplines that call for a significant amount of scientific evaluation and strong decision making, and the present study shall lay down the baseline analysis of the impact of changing LULC on the geomorphological setup of the selected urban center.

Urban fringe development has become a global concern in the last decade, especially as cities continue to expand phenomenally, particularly in the Global South. Urban fringe development is a complex process that involves activities such as change in land, ownership patterns, land transfer processes, regulatory measures and enforcement. This paper examines the pattern of urban fringe development in Ado-Ekiti in South-Western part of Nigeria, focusing on the character of the population, housing types and conditions, availability and quality of infrastructure and the effects on quality of life. Primary and secondary data were obtained for the study. The study revealed that most of the fringe areas in Ado Ekiti lack adequate basic socio-economic amenities such as schools, health centres, recreational facilities, etc., as well as infrastructural facilities like adequate road network, electricity and water supply, drainage and sewage disposal, etc. Statistical data analysis also revealed that the income level of the population has significant effect on urban fringe development. Some of the recommendations for improving the situation include enlightenment of the citizenry the introduction of physical planning education to schools, proper planning, monitoring and enforcement of physical development activities in the fringe areas by government.

Two phenomena playing important role in affecting water resources all over the world are: urbanization and climate changes. Urban and peri-urban water bodies are very vulnerable to these phenomena in terms of quality and quantity protection. This study was aimed to perceive the impact of ever-increasing urbanization on water quality in the catchment area of Rawal Lake. Rawal Lake supplies water for domestic use to Rawalpindi city and Cantonment area. The water was found biologically unfit for human consumption due to total and faecal coliformus counts higher than WHO limits. Similarly, turbidity and calcium was more than WHO standards. There should be detailed study on climate change parallel to urbanization in the Rawal catchment to quantify its impacts on water quality and inflows.

Purpose The purpose of this study was to identify levels of self-compassion in adults who do and do not stutter and to determine whether self-compassion predicts the impact of stuttering on quality of life in adults who stutter. Method Participants included 140 adults who do and do not stutter matched for age and gender. All participants completed the Self-Compassion Scale. Adults who stutter also completed the Overall Assessment of the Speaker's Experience of Stuttering. Data were analyzed for self-compassion differences between and within adults who do and do not stutter and to predict self-compassion on quality of life in adults who stutter. Results Adults who do and do not stutter exhibited no significant differences in total self-compassion, regardless of participant gender. A simple linear regression of the total self-compassion score and total Overall Assessment of the Speaker's Experience of Stuttering score showed a significant, negative linear relationship of self-compassion predicting the impact of stuttering on quality of life. Conclusions Data suggest that higher levels of self-kindness, mindfulness, and social connectedness (i.e., self-compassion) are related to reduced negative reactions to stuttering, an increased participation in daily communication situations, and an improved overall quality of life. Future research should replicate current findings and identify moderators of the self-compassion–quality of life relationship.

Lung cancer is one of the most commonly diagnosed cancers across Northern America and Europe. Treatment options offered are dependent on the type of cancer, the location of the tumor, the staging, and the overall health of the person. When surgery for lung cancer is offered, difficulty swallowing is a potential complication that can have several influencing factors. Surgical interaction with the recurrent laryngeal nerve (RLN) can lead to unilateral vocal cord palsy, altering swallow function and safety. Understanding whether the RLN has been preserved, damaged, or sacrificed is integral to understanding the effect on the swallow and the subsequent treatment options available. There is also the risk of post-surgical reduction of physiological reserve, which can reduce the strength and function of the swallow in addition to any surgery specific complications. As lung cancer has a limited prognosis, the clinician must also factor in the palliative phase, as this can further increase the burden of an already compromised swallow. By understanding the surgery and the implications this may have for the swallow, there is the potential to reduce the impact of post-surgical complications and so improve quality of life (QOL) for people with lung cancer.
