The impact of foreign direct investment and openness on Vietnamese economyThai, Tri Do January 2005 (has links)
This thesis examines the impact of foreign direct investment (FDI) on Vietnamese economy based on Partial Adjustment Model and time series data from 1976 to 2004. FDI is shown to have not only short run but also long run effect on gross domestic product (GDP) of Vietnam. However, elasticity of GDP with respect to FDI is small and it will take many years to fully manifest itself. The impact of trade openness on GDP has also been examined and it is shown to be stronger than that of FDI. The paper offers a number of explanations and discusses briefly suggestions in order to increase the contribution of FDI to Vietnam’s economic development.

ROLE OF LINEAR REPRESENTATION OF LARGE MAGNITUDES ON UNDERSTANDING AND ESTIMATIONResnick, Ilyse Michelle January 2013 (has links)
Having a linear representation of magnitude across scales is essential in understanding many scientific concepts (Tretter, et al., 2006a) and is predictive of a range of mathematical achievement tests (Siegler & Booth, 2004). Despite the importance of understanding magnitude and scale, people have substantial difficulty comparing magnitudes outside of human perception (e.g., Jones, et al., 2008). The present work aims to examine the way people learn to represent and reason about large magnitudes through the development of two science of learning activities based on hierarchical alignment activity and corrective feedback. The hierarchical alignment activity utilizes several analogical reasoning principles: hierarchical alignment, progressive alignment, structural alignment, and multiple opportunities to make analogies. Study 1 examines the effectiveness of hierarchical alignment by contrasting it with a conventional activity that uses all the analogical reasoning principles described above except for hierarchical alignment. Study 2 examines a corrective feedback activity, based on the same analogical reasoning principles used in study 1, except, using corrective feedback instead of progressive alignment and hierarchical alignment. Thus, study 2 examines the necessity of hierarchical and progressive alignment. That both activities were successful in developing linear representations of geologic time (and for study 1, astronomical distances), suggests that multiple opportunities to make analogies through structural alignment are key components in developing analogies for learning magnitude. There appears to be an additive benefit of including hierarchical alignment (i.e., practice aligning magnitude relations across scales) in analogies for learning about magnitudes. Corrective feedback may also be a useful strategy in learning about scale information. Pedagogical implications are discussed. Both activities were based on the hypothesis that magnitudes at scales outside human perception are represented and reasoned about in the same way as magnitudes at human scales. The Category Adjustment Model (Huttenlocher, et al., 1988) suggests magnitude at human scales is stored as a hierarchical combination of metric and categorical information. People may use category boundaries to help make estimations in lieu of precise metric information. Variation in estimation, therefore, occurs because of imprecision of category boundaries (Shipley & Zacks, 2008; Zacks & Tversky, 2001). The current studies provided salient category boundaries to develop a more linear representation of magnitude. Thus, the effectiveness of the hierarchical alignment activity and the corrective feedback activity supports the hypothesis that people use hierarchically organized categorical information when making estimations across scales and across dimensions; and that providing people with more salient category boundary information improves estimation. Similarities and differences among temporal, spatial, and abstract line estimations are identified. Theoretical implications, including the potential application of the Category Adjustment Model to mental number lines, are discussed. / Psychology

Assessing Fraud Risk, Trustworthiness, Reliability, and Truthfulness: Integrating Audit Evidence from Multiple SourcesAbell, Meghann Lynn 14 June 2010 (has links)
To assess fraud risk, auditors collect evidence in a sequential manner by reviewing workpaper documentation, and by collecting corroborating and clarifying information from financial (management) personnel and nonfinancial (operating) personnel. SAS 99 (AICPA, 2002) noted that audit evidence gathered from financial personnel may be susceptible to deception. In addition, prior researchers have found auditors to be poor at detecting deception immediately following deceptive communication. Though the audit process is sequential and iterative, these studies measured auditors– ability to detect deception at a single point and did not provide corroborating evidence after the deceptive communication for auditors to revise their judgments. In this study, I examined auditors’ fraud risk assessments and truthfulness judgments throughout the audit process when there was an attempt at deception by management (financial) personnel. The belief adjustment model provided a framework to examine auditors’ initial judgments, their judgments directly following a deception attempt by financial personnel, and their judgments after receiving corroborating evidence from nonfinancial personnel.
Sixty-four experienced auditors electronically completed one of four randomly assigned cases and, within each case, assessed the fraud risk, truthfulness, trustworthiness, and reliability of financial personnel at multiple points for a fictitious client. I manipulated the presence (absence) of fraud and the level of experience of the source of corroborating evidence (operating personnel). I hypothesized that auditors would not be able to differentially evaluate fraud risk and truthfulness judgments of financial personnel between the fraud and no fraud conditions when exposed to workpaper documentation and deceptive client inquiry evidence by management (financial personnel). However, I expected to find that auditors– would update their fraud risk and truthfulness judgments as they reviewed audit evidence from nonfinancial (operating) personnel.
The results indicate that auditors in this study are not able to appropriately assess fraud risk and the truthfulness of financial personnel following the review of workpaper and client inquiry evidence. While the client was deceptive in the fraud condition only, auditors did not differentially assess the fraud risk and truthfulness of financial personnel between the fraud and no fraud conditions. After auditors reviewed evidence from nonfinancial personnel, in the presence of fraud, auditors increased their fraud risk and decreased their truthfulness judgments of financial personnel as inconsistent evidence was presented from a corroborating source. Therefore, in the presence of fraud, auditors improved the effectiveness of the audit process by appropriately increasing their fraud risk assessments in light of inconsistent audit evidence from nonfinancial (operating) personnel. Of equal importance, in the absence of fraud, auditors decreased their fraud risk assessments as consistent evidence was presented from a corroborating source. Therefore, auditors increased the efficiency of the audit process by appropriately decreasing their fraud risk assessments after integrating consistent audit evidence from nonfinancial personnel into their judgments. Further, I observed that these auditors revised their fraud risk assessments to a greater extent when audit evidence was provided by a source with a higher level of experience.
Though prior research has found auditors to be poor at detecting deception, the results of this study indicate that auditors will increase or decrease their fraud risk assessments and truthfulness judgments based on the consistency of audit evidence gathered from a corroborating source. Therefore, in practice, auditors may be able to detect deception as the audit progresses. / Ph. D.

Oil Dependencies and Peak Oil's Effects on Oil Consumption : A case study of six countriesTekin, Josef, Hagman, Jens January 2007 (has links)
During the year of 2007, the world has experienced historically high oil prices both in nominal and in real terms, which has reopened discussions about energy sustainability. We therefore found it interesting to research oil dependencies and elasticities for Brazil, China, Norway, South Korea, Sweden and USA; and their possible oil consumption response to a Peak Oil phenomenon. Peak Oil in this thesis, implies that oil production will reach its climax and decline thereafter. To help draw conclusions, appropriate statistical analysis on macroeconomic variables was used as well as the modified Nerlove’s partial adjustment equation to calculate price and income elasticities both in the short and long-run. Regression results have shown that short-run price elasticities were low in all countries; in addition income elasticities were also inelastic but more elastic in relation to oil price elasticities. This indicates that oil consumption is more sensitive to changes in income than to changes in oil price. It was concluded that oil dependencies among nations differ and the trend is that developing countries are increasing their oil dependency while developed countries tend to decrease their oil dependency over time. Peak Oil will lead to higher oil prices, which in the short-run will change developing countries oil consumption to a greater extent than developed countries, but in the long-run their response are more similar. It was also noticed, that when GDP decreases in net-oil-importing countries, oil consumption will decrease even further. The opposite could be true for net-oil-exporting countries like Norway and Brazil. / Under år 2007 har världen upplevt historiskt höga oljepriser, både i nominella och reala termer, vilket återigen har lyft upp energiförsörjningen på agendan. Vi fann det därför intressant att undersöka oljeberoenden i Brasilien, Kina, Norge, Sydkorea, Sverige, USA och se hur dessa länders oljekonsumption kan påverkas av Peak Oil. Peak oil betyder att oljeproduktionen når sitt maximum och minskar därefter. För att kunna dra slutsatser har lämpliga statistiska verktyg använts på olika makroekonomiska variabler och applicerat ”Nerlove’s partial adjustment model” på data har pris-och inkomstelasticiteten av olja i varje land både på kort och lång sikt kunnat utvinnas. Från regressionen har framträtt; priselasticiteten var låg på kort sikt i alla länder och detta gäller även för inkomstelasticiteten, dock var inkomstelasticiteten relativt mer elastisk i alla länder. Detta indikerar att oljekonsumtionen är mer känslig för förändringar i inkomst än för förändringar i pris. Slutsatsen från studien är att olika länder har olika nivåer av oljeberoende och att utvecklingsländer tenderar att öka sitt relativa oljeberoende över tid medan de industrialiserade länderna tenderar att minska sitt relativa oljeberoende över tid. Peak Oil leder till högre oljepriser vilket på kort sikt kommer att påverka utvecklingsländernas oljekonsumtion mer än de industrialiserade ländernas, dock minskar skillnaden på lång sikt. En observering från denna forskning är att när BNP minskar hos olje-importörerna kommer även oljekonsumtionen att minska. För oljeexportörer som Brasilien och Norge kan oljekonsumptionen öka när BNP inkomsterna ökar från Peak Oil.

An Analysis of Corporate Real Estate Strategies to the Return and Risk of Shareholders: Taiwan¡¦s CaseCho, Sheng-En 07 July 2011 (has links)
This study examines whether different corporate real estate (CRE) strategies affect the stock outperformance and systemic risk of various companies. The sample of 443 listed companies of 17 industries in Taiwan during 2000 to 2010 was divided into four groups for the different corporate real estate strategies. The pairwise abnormal return and systemic risk of composite and business (without the affect from real estate market) series were empirically examined and compared using a partial adjustment model. This study also conducts the two-stage least squares procedure to determine whether four CRE strategies were considered diversifiable factors when evaluating the firm¡¦s value
The results do not indicate an increasingly abnormal return performance associated with the company implementing a certain CRE strategy, but companies with a stable profession and consistent adjustment strategies are considered a good diversifier by stock investors. Aggressive adjustment strategies do not diversify the systematic risk to overall industry, otherwise the scale of total assets would be considered a diversification in companies with aggressive strategies. The companies using an aggressive profession strategy to increase leverage are regarded as risky phenomen for stock investors, and companies with stable profession strategies face higher systemic risk if their book value is greater than their market value. Therefore, this study determines that CRE strategies affect companies¡¦ systematical risk.

EXTENDING THE CATEGORY ADJUSTMENT MODEL: LOCATION MEMORY BIASES IN 3-DIMENSIONAL SPACEHolden, Mark Paul January 2011 (has links)
The ability to remember spatial locations is critical to human functioning, both in an evolutionary and an everyday sense. And yet, spatial memories and judgments often show systematic errors. Explanations for such errors have ranged from assumptions that memories are nonmetric, to the use of imperfect inferences, to the optimal combination of multiple sources of information. More recently, bias has been explained through the Category Adjustment Model - a Bayesian model in which fine-grained and categorical information are optimally combined (Huttenlocher, Hedges, & Duncan, 1991). However, experiments testing this model have largely used locations contained in simple geometric shapes. Use of this paradigm raises the issue of whether the results generalize to location memory in the complex natural world, as it should if it is to provide an over-arching framework for thinking about spatial memory. Here, this issue is addressed using a novel extension of the location memory paradigm that allows for testing of location memory in an everyday, 3D environment. The results support two predictions of the Category Adjustment Model - that memory for locations is biased toward central values, and that the magnitude of error increases with the retention interval. Future directions for testing the model in an increasingly ecologically valid manner are discussed. / Psychology
