Sources and directions of social support and life satisfaction among solitary Chinese older adults in Hong Kong: the mediating role of sense of loneliness

Based on survey data collected from 151 community-dwelling solitary Chinese older adults in Hong Kong, the present study used path analysis to examine the mediating role of sense of loneliness in the relationship between different sources and directions of social support and life satisfaction. The results showed that sense of loneliness mediated the effects of support from families, friends, and support for others on life satisfaction. In addition, a formal source of social support was not associated with life satisfaction among solitary older adults, although those with a more secure financial status had greater overall life satisfaction. These findings highlight the importance of enhancing awareness among social and health care service providers about the negative effects of insufficient social support on older adults’ sense of loneliness and life satisfaction. Family and friendship networks should be expanded for solitary older adults

Analytical Modelling of Formation Damage in One-phase and Two-phase Flows: Applications for Laboratory Experiments

I hereby present a Ph.D. thesis by publication. This thesis includes six journal publications, four of which have been published and two have been submitted for publication. This thesis is focussed on the application of analytical modelling in laboratory experiments of formation damage in one-phase and two-phase flows in porous media. It targets formation damage with chemical reactions, fines migration, as well as onedimensional (1D) and two-dimensional (2D) two-phase flows accounting for capillary end effects. The thesis develops a novel system of fundamental equations for reactive flows with large deposition of solid reaction products. A new class of exact analytical solutions has been derived for reactive flows with any arbitrary stoichiometric coefficients. The analytical solution yields breakthrough concentration and pressure drop type curves, significantly facilitating the interpretation of the laboratory data. The developed system of governing equations has been validated by laboratory modelling and can be used for the prediction of mineral precipitation chemical reactive flows in porous media. In addition, the three-point pressure method for large scale deposits has been investigated for the first time and the results show that the inclusion of outlet concentration data significantly decreases parameter uncertainty. The large parameter uncertainties without using outlet concentration arise due to the inability for the model to distinguish between a set of deposit profiles. Laboratory studies applying the three-point pressure method have also been conducted for fines migration in porous media to predict formation damage in a hydraulically fractured well. The results show that while pressure measurements alone can predict formation damage due to fracture fluid leak-off, breakthrough fines concentration is able to fully predict model functions and coefficients to characterise the system. The two-phase flow in porous media investigated in this thesis comprises steady-state and transient 1D flow with capillary end effects, and steady-state 2D flow with capillary end effects near a hydraulically fractured production well. Steady-state analytical solutions, along with transient numerical solutions, have been applied in the so-called steady-state-transient test (SSTT). It includes a three-dimensional (3D) modelling of the SSTT with the treatment of the simulated data by a 1D inverse solver. The main result shows a significant reduction in the 3D flow effects when using an inlet distributor with spiral (or concentric-circle) grooves rather than one with halfmoon grooves. Following this result, two SSTTs were carried out in the laboratory. In the concentriccircle SSTT, a weighting method for water cut measurements at the effluent was used, while in the half-moon SSTT, a visualisation method was used. Based on the results, the use of a concentric-circle distributor and the weighting method in SSTTs is recommended. Lastly, the exact solution to the steady-state 2D flow towards a fractured well was derived and applied to predict formation damage due to capillary-trapped water, known as water blocking. The results show water blocking is likely to be a significant factor in the productivity decline for the case study conducted.Thesis (Ph.D.) -- University of Adelaide, Australian School of Petroleum and Energy Resources, 202

A Review of Current Studies on Internet Finance in China

The Internet and finance are accelerating into integration in the 21st Century. Internet Finance was firstly proposed by Ma Weihua, the former president of China Merchants Bank in July 2012. On the basis of 74 latest research literatures selected from CSSCI Journals, Chinese Core Journals, authoritative magazines and related newspapers, this paper summarizes the current domestic research progress and trend about Internet Finance according to three dimensions, such as the sources of journals, research subjects and research contents. This research shows that the current domestic researches are not only shallow and superficial, but also lack the theoretical analyses and model applications; and the wealth-based and bank-based Internet Finance will be the research focus in the future

The title compound, C19H10BrCl2F3N4O, is an imine with an overall Y shape. The dihedral angles between the pyrazole ring and the methoxy- and trifluoromethyl-substituted benzene ring planes are 88.4 (2) and 65.8 (2)°, respectively

A Semantic Search Engine Based on SKOS Model Ontology in Agriculture

Abstract. A simple agriculture ontology system was constructed under extended SKOS model in this paper. A theme relevance algorithm based on terms' distances in ontology system was tested and applied in improving the Pagerank evaluating. And also an online agricultural semantic search engine named as Sonong was implemented and deployed for service on internet. This online engine provides semantic hierarchy inference with the ontology system and a satisfying ranking list of retrieved information

Causal Reasoning of Entities and Events in Procedural Texts

Entities and events are crucial to natural language reasoning and common in procedural texts. Existing work has focused either exclusively on entity state tracking (e.g., whether a pan is hot) or on event reasoning (e.g., whether one would burn themselves by touching the pan), while these two tasks are often causally related. We propose CREPE, the first benchmark on causal reasoning of event plausibility and entity states. We show that most language models, including GPT-3, perform close to chance at .35 F1, lagging far behind human at .87 F1. We boost model performance to .59 F1 by creatively representing events as programming languages while prompting language models pretrained on code. By injecting the causal relations between entities and events as intermediate reasoning steps in our representation, we further boost the performance to .67 F1. Our findings indicate not only the challenge that CREPE brings for language models, but also the efficacy of code-like prompting combined with chain-of-thought prompting for multihop event reasoning.Comment: In Findings of EACL 202

Improvement of hybrid grouper (Epinephelus fuscoguttatus ♀ × E. lanceolatus ♂) by enzyme-digested poultry by-product: Growth performance, amino acid and peptide transport capacity, and intestinal morphology

BackgroundAt present, fish meal (FM) resources are in short supply, and competition for food between humans and animals is becoming increasingly critical. Finding non-grain protein sources that can replace FM is the key to solving the rapid development of aquaculture.MethodsSeven trial diets were prepared with 0 g/kg (EP0), 30 g/kg (EP3), 60 g/kg (EP6), 90 g/kg (EP9), 120 g/kg (EP12), 150 g/kg (EP15), and 180 g/kg (EP18) of enzyme-digested poultry by-product meal (EPBM) by replacing of FM. A total of 630 hybrid groupers (Epinephelus fuscoguttatus ♀ × E. lanceolatus ♂) were equally portioned into 21 tanks. At 8:00 and 16:00 each day, groupers were fed until they were full for a cumulative period of 8 weeks.ResultsThe results showed that 30 g/kg of EPBM significantly increased the rates of weight gain and special growth (P < 0.05). Significantly higher activities of serum glutamic pyruvic transaminase, glutamic oxaloacetic transaminase, catalase, and superoxide dismutase were observed in the EP3 group (P < 0.05). The categories and numbers of the top 10 dominant bacteria in the phylum and genus levels were not significantly influenced by feed (P > 0.05). In the proximal intestine and distal intestine, there were significantly higher expressions of SNAT3, LAAT1, CAT2, and CAT1 in the EP3 group compared with the EP0 group (P < 0.05). In the EP3 group, the expressions of PepT1, LAAT1, B0, +AT, and CAT2 were significantly increased in MI than those in all other groups (except the EP0 group, P < 0.05).ConclusionWhen FM was replaced by 30 g/kg of EPBM, growth performance, antioxidant capacity, and the ability to transport amino acids and peptides of hybrid grouper were significantly improved
