Macao ( 30 Km2) is a territory characterized by small granitic intrusions, located along the coastal region of Southeast China (Cathaysia Block). Granitoids occur as different facies, including microgranite dykes, with distinct textural, mineralogical and geochemical features, for which a middle-upper Jurassic age ( 164 Ma) has been proposed. New data suggest that these granitoids are mostly high-K calc-alkaline metaluminous (A/CNK = 0.8 - 1.1) biotite granites, consistent with total absence of primary muscovite. They show variable amounts of SiO2 (67-77%), reflecting different degrees of magmatic evolution. There is also variability in terms of trace elements, particularly Rare Earth Elements (REEs), evidenced by decreasing (La/Sm)N, (Gd/Lu)N, (Ce/Yb)N and (Eu/Eu*)N towards the more evolved samples, which can be partly attributed to fractional crystallization processes. Most of the granitoids are characterized by (La/Yb)N = 3 - 10.8, showing negative Ba, Nb, Sr, Zr, P, Ti and Eu anomalies. On the other hand, microgranite dykes, along with a few more evolved granites, show an opposite tendency, being usually enriched in HREEs relatively to LREEs with (La/Yb)N = 0.4 - 1.1. Our data suggests intermediate genetic affinities between I-type and A-type granites. Although these granitoids are mostly metaluminous (characteristic of I-types), Ga/Al ratios, usually used to identify A-types, are close to the accepted boundary between A-type and other granite types. The affinities with A-type granites are more marked for the more evolved facies, which depict higher values of FeOt/MgO (14 - 60) and K2O/MgO (60 - 250). Their trace element characteristics are also transitional between WPG (Within-plate granites) and Syn-COLG (Collision Granites). We interpret those transitional characteristics (A/I and WPG/Syn-COLG) of Macao granitoids as reflecting an origin by melting of infracrustal sources over a period of high heat transfer from mantle to crust during an extensional tectonic setting probably contemporaneous with the subduction of the paleo-Pacific plate beneath the Eurasia, whose paleo-suture is thought to be located in the east flank of the Central Range, Taiwan.

Kruger and Dunning (1992) found that unskilled people were typically unaware of their own performance and ability. In this context, unskilled performers were shown to overestimate their performance and ability, whereas skilled performers often accurately predicted their own performance and ability. Such miscalibration in self-assessment is usually attributed to a lack of so-called metacognitive skills necessary for performance evaluation. However, it remains unknown to what extent the miscalibration of performance judgment and optimistic bias is observed in the Chinese culture. This thesis examines patterns of miscalibration of performance judgment and specific optimistic bias. This thesis also builds on a range of previous studies of performance judgment and optimistic bias. In order to investigate the performance judgment and optimistic bias in this context, two studies were conducted as part of the research aspect of this thesis. In the first study, participants were given a reasoning task on which they had to predict their performance before completing the task and estimate their performance upon completion of the task. The second study followed similar methodology, with two additional tasks – Institute For Tourism Studies (IFT) module and the respective midterm examination. Results from both studies indicate that biases in performance judgment occur in the Chinese culture, and may yield negative consequences to those persons who exhibit such judgments. Although metacognitive ability provides some explanation for the miscalibration of performance judgment, the results of the current study indicate that task optimistic bias provides another, equally viable explanation for the miscalibration of performance judgment. The findings presented in this thesis suggest that inaccurate judgments of performance occur within various domains (general and specific iii performance contexts) and that there are a range of implications associated with these biases. Keywords: Miscalibration of performance judgment, optimistic bias, absolute optimistic bias, comparative optimistic bias, overestimation, overplacement, underestimation, underplacement

This paper introduces a concept proposal for accessing driving behavior in public transportation through Mobile Crowd Sensing (MCS), as part of a long-term research project on Advanced Public Transportation System (APTS). The proposed concept makes use of mobile device's accelerometer and passengers' qualitative evaluation to identify aggressive driving behavior, which is believed to be a major factor for unnecessary accidents and fuel consumption. A survey and comparison of IT services (mobile applications and websites) provided by Macau Government and private bus companies in Macau, regarding bus-related information, such as fares, routes and route diversions is also provided.

Secondary schools do not have the same technical resources and capabilities as universities. They usually need to rely on ready-to-use tools to fulfill their information and communication technology (ICT) structure. Social networking site (SNS) has emerged as a practical solution to this need. However, few have collected empirical data on the application of SNS in a secondary school setting. This paper probes into the current condition of SNS usage among secondary school students using a sample of 851 students in Macau, a Special Administrative Region (SAR) of China. Data in terms of access, profile and activities are collected. The activities on SNSs are analyzed by regression techniques to produce a prediction model relating perceived academic benefit and SNS activities. The model yields a strong positive relationship between that benefit and activities such as raising questions and engaging in study-related discussions. The model also yields a weak dependency on activities such as searching for information and entertainment. The paper also evaluates the actual academic utilization of a Facebook Group for one class of secondary school students for a period of one year. At the end of the year, various opinion parameters are measured, and improvements are observed in most parameters.
