Essays on dynamics of the housing market : a thesis presented in fulfilment of the requirement for the degree of Doctor of Philosophy in Finance at Massey University, Albany, New Zealand

Listed in 2021 Dean's List of Exceptional ThesesAs the largest proportion of a household’s wealth is invested in houses, a household’s saving and consumption is highly likely to be affected by the movement of housing markets. Economists are also very interested in housing price movements, due to its significant impact on general economic wellbeing and business cycles. The US housing collapse is commonly referred to as the trigger of the global financial crisis (GFC), leading to stronger demand from both the public and policymakers for in-depth analysis of housing markets. This thesis provides three empirical studies that aim to explore the dynamics of housing markets. The first essay analyses the relationship between immigration and housing markets with a focus on the regional differences within a country. Among the three housing market indicators studied (prices, rents, and price-to-rent ratios), the impact of immigration is found to be most strongly associated with rents and most weakly associated with prices. A negative relationship is reported between immigration and price-to-rent ratios, implying that in an overvalued housing market, the extent of deviation from equilibrium would have been even greater without immigration. Increased global financial integration as a result of improvements in the specification of trade, innovations in finance, and advances in information technology has led to increased connectedness between financial markets. Against this backdrop, the second essay measures the equicorrelation and connectedness between housing and oil markets. The results provide robust evidence of the existence of strong connectedness between these markets. The results also indicate that the connectedness is time variant, reaching its peak during the financial crisis. Among the studied markets, the US housing market is found to be the dominant shock transmitter, spreading shocks to the other markets. During the GFC period, the oil market operated as an information transmission mediator, conveying shocks from the US housing market to other OECD housing markets, particularly in the net oil importing OECD countries. The third essay focuses on whether capital gain in housing markets smooths consumption. The results indicate that the appreciation of house prices is an effective channel of risk sharing. Furthermore, the analysis of the consumption response to long-run output shocks in three developed countries (Australia, Canada, and New Zealand) provides evidence that Canadian residents are the most sensitive to permanent domestic output shocks and that the consumption patterns of Australian residents remain unchanged

THE EFFECTIVENESS OF EXPERIENTIAL LEARNING MODELS IN TEACHER TRAINING: A CASE STUDY IN THAI NGUYEN PROVINCE, VIETNAM

The quality of education may be raised in large part by investing in teacher training. It contributes to the expansion and updating of professional knowledge, teaching abilities, and new and improved methods of approaching students. Teachers can also continue to grow individually via the refresher process, reflect on their teaching methods, and adjust to shifts in the educational landscape and the needs of their students. The purpose of the project is to identify an experiential learning-based teacher training paradigm that is efficient and workable. A pedagogical experiment using this model was conducted with two classes and 35 high school teachers in Thai Nguyen Province, Vietnam. The findings of the research, which used the document research approach together with expert opinion, demonstrate that learning via experience in teacher training has accomplished the desired objective in 5 key stages: (1) (1) Choosing a few standard lessons to organize to teach illustrations; (2) preparing to organize the illustration teaching after the standard lesson has been chosen; (3) practicing demonstration teaching; (4) organizing the discussion after attending the demonstration lesson; and (5) making personal plans to organize the lesson in accordance with the training's content.  Article visualizations

Topological Lifshitz phase transition in effective model of QCD with chiral symmetry non-restoration

The topological Lifshitz phase transition is studied systematically within an effective model of QCD, in which the chiral symmetry, broken at zero temperature, is not restored at high temperature and/or baryon chemical potential. It is found that during phase transition the quark system undergoes a first-order transition from low density fully-gapped state to high density state with Fermi sphere which is protected by momentum-space topology. The Lifshitz phase diagram in the plane of temperature and baryon chemical potential is established. The critical behaviors of various equations of state are determined.Comment: 8 pages, 10 figure

IMPACTS OF CLIMATE CHANGE AND SEA LEVEL RISE ON SALINITY INTRUSION IN THE LOWER DONG NAI RIVER SYSTEM

Ho Chi Minh City (HCMC) is ranked among the top 10 cities in the world most likely to be severely affected by climate change and sea level rise (SLR). This study was to assess the impacts of change of upstream flow and sea level rise due to climate change on salinity intrusion in HCMC. The MIKE 11 model with modules hydrodynamic (HD) and advection-dispersion (AD) was applied to this problem by setting up the whole lower Dong Nai river system. Based upon the observed water level and salinity concentration data in 2009, the calibration and validation results indicated that the MIKE11 model was able to simulate the streamflow and salinity concentration with NSE values exceeding 0.6 for both calibration and validation periods. As a result, the differences in salinity concentration under climate change and SLR scenarios were analyzed. The simulated results illustrate that the saltwater will move inland in the future, especially in the dry season

The Potential of Beauveria against Root Mealybugs Formiccoccus sp. (Homoptera: Pseudococidae) Black Pepper in Dak Lak Province of Vietnam

Root mealybugs Formicoccus sp.(Hemiptera: Pseudococcidae) currently emerge as an economically important soil-borne insect pest in the production of black pepper (Piper nigrum L.) in Dak Lak province of Vietnam. Entomopathogenic fungi can be used in agricultural production as feasible safe biocontrol agents and plant growth promoters. This study aimed to isolate, select and identify the local Beauveria sp. strains from the black pepper fields, as well as evaluate the effects of the selected strains on the growth of black pepper. The results showed that the frequency of positive Beauveria sp. soil samples collected from organic black pepper fields was significantly higher than that from conventional black pepper fields. Twenty-one Beauveria sp. strains in black pepper organic fields and four Beauveria sp. strains in black pepper conventional fields were successfully isolated, among them, the Beauveria bassiana BB1 was examined and evaluated for its biocontrol potential against Formicoccus sp. and its ability to promote the growth of black pepper seedlings. In the laboratory experiments, the mortality of both adults and first instar nymph root mealybugs Formicoccus sp. caused by B. bassiana BB1 culminated 100% at 21 days after treatments. In the nethouse, at 6 months after treatment, the efficacy of B. bassiana BB1 against black pepper root mealybugs reached 99.18%. The levels of photosynthetic pigments in the leaves of the black pepper seedlings increased about 2 times compared to the control. Moreover, B. bassiana BB1 strain also remarkably promoted the growth of the black pepper seedlings under the nethouse conditions

Investigation of the pollution status and the waste reusing ability in trade village Duong Lieu, Hoai Duc, Hanoi: Short communication

Vietnam has about 2,000 trade villages locating mainly in the north. Duong Lieu village in Hoai Duc, Hanoi, is one of the key areas of agricultural production and food processing. However, this area is affected by serious environmental pollution, particularly caused by solid waste and wastewater. Solid wastes of the starch production process from arrowroot are disposed in large amounts and represent the main reason for environmental pollution in Duong Lieu village. These wastes are present anywhere in this village, for example on the main road, in gardens, event fill in ponds and ditches. The components of the dried arrowroot waste are mainly carbon-rich substances such as starch (5%), cellulose (90%) and N, P, K (0.5%; 0.11%; 0.16%, respectively). The fresh arrowroot waste has humidity of up to 80%. This substrate is suitable for culture of straw mushroom and oyster mushroom. The mushrooms use cellulose as carbon source for their growth. Therefore, waste from arrowroot that can be recycled efficiently by the biological method for culturing mushrooms. This treatment method is suitable to the conditions of Vietnam because it does not only reduce waste residues but also is environmentally friendly.Việt nam có khoảng 2000 làng nghề và tập trung chủ yếu ở miền Bắc. Dương Liễu là một trong những vùng trọng điểm chế biến nông sản thực phẩm. Song hiện tại khu vực này đang bị ô nhiễm môi trường nghiêm trọng,đặc biệt ô nhiễm rác thải và nước thải. Chất thải rắn của quá trình chế biến tinh bột từ củ dong là rất lớn. Nó có mặt khắp nơi từ trong nhà ra ngoài ngõ thậm chí lấp đầy cống rãnh, ao hồ. Đây chính là nguyên nhân gây nên ô nhiễm môi trường vùng làng nghề. Thành phần của bã dong rất giàu cellulose (90%), tinh bột (5%) và có cả nitơ, photpho, kali tương với 0,5%, 0,11% và 0,16%; độ ẩm của bã dong tươi lên tới 80%. Cơ chất này thích hợp để trồng nấm rơm và nấm sò. Bởi các loại nấm này sử dụng cellulose là nguồn cung cấp cacbon chính để sinh trưởng. Do vậy, bã thải từ củ dong có thể được tái sử dụng hiệu quả bằng phương pháp sinh học như là dùng trồng nấm. Đây là một sự lựa chọn phù hợp với điều kiện Việt Nam, vừa giảm thiểu chất thải dư thừa vừa thân thiện với môi trường

Design and fabrication of a moving robotic glove system

This paper presents the research, design, and manufacture of a robotic hand to control movement with a glove. The moving glove-controlled robotic hand is based on two main parts: the hand mechanism and the control circuit. The control glove unit includes an Arduino nRF24l01 microcontroller module and five flex sensors for five fingers. These sensors are used to collect data about the curvature of each finger. Then those data will be received by the Arduino microcontroller and sent by the nRF24l01 module. The hand's microcontroller will process that information and control five servo motors so that the five fingers of the robotic hand are moved. The result of this research is to produce a robotic hand that accurately simulates the curvature of a user's finger and mimics the motion of a glove well. Moreover, the robot hand can grip objects of different sizes (from 0.1 to 1 kg) and shapes, from which this robot helps users easily manipulate objects
