    Abstract Nucleotide mutations in human genes have long been a hot subject for study because some of them may lead to severe human diseases. Understanding the general mutational process and evolutionary trend of human genes could help answer such questions as why certain diseases occur and what challenges we face in protecting human health. In this study, we conducted statistics on 89,895 single-nucleotide variations identified in coding regions of 18,339 human genes. The results show that C and G are frequently mutated into T and A in human genes. C/G (C or G)-to-T/A mutations lead to reduction of hydrogen bonds in double-stranded DNA because C-G and T-A base pairs are maintained by three and two hydrogen bonds respectively. C-to-T and G-to-A mutations occur predominantly in human genes because they not only reduce hydrogen bonds but also belong to transition mutation. Reduction of hydrogen bonds could reduce energy consumption not only in separating double strands of mutated DNA for transcription and replication but also in disrupting stem-loop structure of mutated mRNA for translation. It is thus considered that to reduce hydrogen bonds (and thus to reduce energy consumption in gene expression) is one of the driving forces for nucleotide mutation. Moreover, codon mutation is positively correlated to its content, suggesting that most mutations are not targeted on changing any specific codons (amino acids) but are merely for reducing hydrogen bonds. Our study provides an example of utilizing single-nucleotide variation data to infer evolutionary trend of human genes, which can be referenced to conduct similar studies in other organisms.

    Abstract Future agriculture faces a twofold challenge: increasing yields to safeguard food security while simultaneously reducing its environmental impact. Ecological intensification has been proposed as a solution to this challenge. It entails the integration of ecosystem service management into farming practices to enhance or maintain yields while minimizing artificial inputs and environmental externalities. An increasing number of empirical studies have shown beneficial effects of ecosystem services on crop production, but the majority of these studies have focused on the effects of only a single ecosystem service in isolation. In contrast, in real-world agricultural systems, crop yield is shaped by several ecosystem services simultaneously. These different ecosystem services may interact (positively or negatively) and their interactions may furthermore depend on agricultural management practices. To assess the potential of ecological intensification in promoting yields and reducing external inputs, it is essential to understand the combined effects of different ecosystem services on agricultural production. The aim of this thesis was to examine whether and to what extent different ecosystem services interactively shape crop yield, and whether and how this is affected by agricultural management. Focusing on raspberry (Rubus idaeus L.), a globally important perennial fruit crop, I examined the potential interactive effects of the ecosystem services provided by insect pollinators, arbuscular mycorrhizal fungi (AMF) and soil organic matter (SOM) on the quantity and quality of raspberry production, and whether these effects were influenced by artificial fertilizer inputs.Natural relatives of commercial raspberry are widespread in temperate forests. These natural relatives depend entirely on several ecosystem services for survival and reproduction. Therefore, investigating the effects of ecosystem services on natural raspberry production would be informative to fully understand their importance, and could act as a ...

    Abstract Assistive technology is increasingly valued to support older people with functional decline and disabilities. Inspired by classical theories on technology acceptance, emotional experience, and psychological needs, this study aimed to better understand the use of assistive technology by older people. Qualitative semi-structured interviews were conducted with 50 community-dwelling older adults in Hong Kong (mean age = 67.47, standard deviation = 7.96). Thematic analysis was used to generate themes. Positive and negative emotional experiences emerged as two themes. The theme of positive emotional experiences is associated with enhanced security, independence, and relativeness. However, assistive technology may also produce anxiety, frustration, stigma, isolation, and risks that induce negative emotional experiences. These findings indicate that older users' emotional and psychological concerns should be addressed and reflected in the process of assistive technology product design and implementation.
