To present the state of the arts application of semantic web technologies in web portals and corresponding achievable improvements for identifying the potential improvement made by semantic web technology.

An evaluation scheme is proposed to investigate various web portals that make use of semantic web technologies in order to identify their strengths and weaknesses. This scheme consists of three layers: information access, information processing and grounding technologies. Two academic portals and two commercial portals are selected based on the definition of semantic web portal. Detailed evaluation based on the proposed scheme is conducted on these four select portals.

Semantic web technologies can definitely increase the information consistency and the information processing quality of web portals by using ontologies to model portal structure and consensus knowledge. Furthermore, semantic web services will be acting as the key technologies to lift current portals to next level.

This paper proposes an elaborated evaluation method for investigating various portals. It reveals the current status of semantic web applications in web portals.

Terrorism has historically been spawned by inequitable, unjust systems with inadequate democratic options to articulate popular aspirations and ensure conflict resolution. The event of September 11, 2001 changed it all when terrorism hit the center of the increasingly globalized post-Cold War international system. The 9/11 incident has played as the role of a catalyst in initiating joint governmental policies to combat international terrorism both in India and the USA. After the incident, the former US President, George W. Bush, announced to the world community to fight against international terrorism collectively on the basis of a zero-tolerance policy. India has been the victim of cross-border terrorism promoted by Pakistan for a long time. India is the world’s largest democracy and one of its fastest-growing economics. Due to the recurrence of terrorist attacks, its security system and its socioeconomic structure have had to face tremendous pressure. Just after the 9/11 incident (attack on WTC) world’s largest (India) and oldest (USA) democracies have come closer to jointly fight against international terrorism. Both al-Qaida and the Taliban were the common enemies for Washington and New Delhi. At the governmental level, a number of policies and working groups have been organized by the two countries in order to diminish global terrorism. This chapter intends to explore the effects of joint governmental policies by India and the USA for combating international terrorism.

Terrorism finance (TF) has been aptly termed as the lifeblood of terrorism. TF provides funds for terrorist activities. Terrorists mobilize funds by using the formal banking system, informal value-transfer systems, hawalas, Hundis, and the oldest method of asset transfer. They may raise funds from legitimate sources, such as personal donations and profits from businesses and charitable organizations, as well as from criminal sources, like the drug trade, the smuggling of weapons and other goods, fraud, kidnapping, and extortion. Countering the financing of terrorism is a far greater challenge throughout the world. The objectives of the chapter are as follows: (1) to identify the different sources of terrorism financing, (2) to analyze various ways of moving terrorism funds globally, and (3) to examine the initiatives taken to counter terrorism financing.

The threat of terrorism is not just limited to a particular nation, rather it has affected the economies of several developed and developing nations. In this study, we have tried to analyze how terrorism has been sought to be tackled and how it can be tackled. In this context, we present the extent to which the method adopted by the USA after the 9/11 attacks, which is popularly called the Global War on Terror (GWOT), has been successful in eliminating terrorism from the world. Only qualitative methodology has been used in this chapter, and most of it has been derived from secondary sources. Through this study, we seek to show that the successes of GWOT have been limited in nature, in spite of tall claims. In fact, what the US has achieved by GWOT in the name of success is the killing of the leaders of some terrorist organizations, successful disruption of their sanctuaries, passing several legislations in order to launch counterterrorism operations, and the freezing the finances of these terrorist organizations by banning some of their charity-based organizations. This chapter lists the gains obtained as a result of GWOT and also highlights what may be called the failures of this global endeavor. Such a proposition aims at showing why GWOT is not only but possibly the best solution to eradicate terrorism. The unexpected outcomes, however, have been many, not only for terrorism but also for international politics, thereby impacting international organizations and also the third-world nations.

This paper uses data from 2010 to 2016 across 32 states and union territories to investigate the determinants of crime in India. Results indicate the significance of macroeconomic, demographic, socioeconomic and deterrence factors in accounting for various categories of crime.

Due to the evidence of heteroskedasticity and cross-sectional dependence, linear regression with panel-corrected standard errors is implemented.

It has been found that among the macroeconomic factors, only GSDP per capita was found relevant in explaining total crime rates. However, the unemployment rate and price level are crucial in explaining some categories of crime. The demographic factor, that is, population density, socioeconomic factors, that is, income inequality, poverty rate, literacy rate exhibit important and significant relationship with crime rates in India. Further, out of the four deterrence factors, charge-sheeting rate, conviction rate, pendency in police cases are important in explaining various categories of crime rates in India.

While implications of some socioeconomic variables are consistent with those found in previous studies, literacy rates and deterrence variables were found to have a positive association with crime. In particular, in a developing country such as India, white-collar crimes tend to increase as literacy rates increase. This calls for implementing policies that lead to greater employment opportunities for the educated masses. This paper also sheds light on the relationship between deterrence factors and crime rates in India. Deficiencies in the legal and judicial system have been detrimental to the nation's ability to curb crime rates.

Rio de Janeiro has a high tourism potential, and it is the only Brazilian city among the 100 most visited in the world. However, the National Confederation of Commerce of Goods, Services and Tourism estimates that from the total loss of revenue from tourism activities of the State of Rio de Janeiro in 2017, approximately 29 percent of this loss can be attributed to increased violence in the State. Thus, this study aims to estimate the impact of violence on tourist arrivals to Rio de Janeiro.

The analysis is based on a sample of tourist arrivals to Rio de Janeiro from 51 countries, for the period between 2003 and 2016. Violence is represented by violent deaths in the State of Rio de Janeiro as well as in the capital. The estimates are based on panel data methodology. This study reports fixed-effect estimates as well as dynamic panel data estimates obtained through S-GMM. The study runs regressions for the full sample and also for two other samples: one with tourists coming from developed countries and another with tourists from developing countries.

The results reveal that violence negatively impacts tourism to Rio, and it shows that tourists from developed countries are more affected by violence than tourists from developing countries. The findings indicate that for each violent death in the capital of Rio de Janeiro, almost four tourists from developed countries and approximately three tourists from developing countries quit going to Rio de Janeiro.

The paper is one of the few to investigate the impacts of urban violence on tourism. The paper provides two contributions. First, it addresses the effect of violent deaths on tourism, bringing evidence to a destination with a high tourism potential, but which suffers from urban violence. Second, the study is the first to investigate whether this relation is different for tourists from countries with distinct levels of development (and thus with different levels of violence).

The purpose of this study is to investigate the effect of corruption on stock returns in the USA. In particular, this study examines the relationship between corruption in a state (i.e. local corruption) and stock returns of firms headquartered in that state (i.e. local returns).

This paper uses the Fama–MacBeth two-step regressions. In the first step, the authors estimate the coefficients on the market, size, value and momentum factors for individual stocks. In the second step, they use those coefficients along with the corruption score of the state where stocks are headquartered to explain stock returns.

This paper finds that corruption in a state adversely affects stock returns of firms headquartered in that state. It further documents that the effect of corruption on stock returns is limited to geographically concentrated firms.

To the best of the authors’ knowledge, this paper is the first to document the effect of state-level corruption on individual stock returns in the USA using the Fama–MacBeth regressions. This study contributes to the literature by documenting the effect of local corruption on local stock returns in a low corruption country.

Due to the high levels of crime in Rio de Janeiro, the purpose of this paper is twofold. The first one is to analyze the effects of deterrence variables (such as the adoption of Pacifying Police Units (UPPs) and incarcerations) on violence in the municipalities of the State of Rio de Janeiro, as well as to verify the existence of “revenge effect.” The second is to analyze the effects of socio-economic development on violence, using development indicators.

Besides usual OLS method for panel data analysis, the study makes use of dynamic panel data framework through D-GMM and S-GMM. The estimates are based on a sample of 82 municipalities of Rio de Janeiro, and the period runs from 2003 to 2013. As dependent variables, the estimates use violent deaths (i.e. aggregation of intentional homicides and armed robberies followed by death) and homicides resulting from opposition to police intervention (i.e. civilians killed as a result of police actions against criminals – “opposition deaths”).

The estimates indicate that incarceration presents marginal capacity to reduce violence. Regarding the findings for the adoption of UPPs, the evidence suggests that this project increased violence and, therefore, the possibility of displacement of violence to other regions of the State. With respect to the effect of police deaths over violence, the results are unprecedented and suggest the existence of a “revenge effect.” Besides, the study points to the importance of socio-economic development to reduce violence.

Once the study analyzes the effects of incarceration and UPPs, it contributes to the literature by providing new evidence on the ability of anti-crime policies of reducing (or not) violence. In addition, when considering the death of policemen in the estimates, the study shows an unprecedented way, the effect that these deaths cause over violence (the so-called “revenge effect”). Moreover, the study considers the impacts of the development of employment and income, health and education on violence. When analyzing these development indicators, the study contributes with the literature that looks for non-police alternatives to control crime.

The purpose of this paper is to examine the influence of major non-economic events, such as the announcement of Greek national parliamentary elections during the period 2000-2009, and search for stock manipulation and methods to detect and recover ill gotten assets. The Financial Sector in Greece is one of the most important and fast growing sectors during recent years and accounts to about 16.17-17.74 per cent of gross domestic product. The ten largest Greek banks listed in the Athens Stock Exchange, accounted to 38.34 per cent of the whole capitalisation of the Athens Stock Exchange during year end 2009.

By using event study methodology and Market Model and analyzing data of all Greek bank stocks prices listed in Athens Stock Exchange, before and after the announcement of four Greek national parliamentary elections during period 2000-2009, we find interesting results about stock market manipulation.

Using daily data from the Athens Stock Exchange, the results of this paper claim that the four Greek national parliamentary elections during the period 2000-2009, had no statistically significant effect on the Greek banks stocks. The results show that Cumulative Average Abnormal Returns (CAARs) were slightly positive or negative for Greek banks’ stocks, but not statistically significant in 5 and 10 per cent confidence levels. Results show no manipulation effect in banks’ stocks even if single-party governments in Greece caused elections early, sudden or even opportunistic timing, having an incentive to attempt to manipulate stocks to increase their chances of re-election.

Results show that CAARs were slightly positive or negative for Greek banks stocks, but not statistically significant in 5 and 10 per cent confidence levels, but when illicit funds or assets have been acquired from stock manipulation, as small as can be, then one fact remains constant. Proceeds from illicit activities must be disguised in some way to avoid being discovered and then being recovered. Especially, during current the financial crisis, debt crisis and the extraordinary liquidity support measures taken by the European Central Bank (ECB), International Monetary Fund (IMF) and European Commission to support Greek economy, using methods to detect and recover ill gotten assets are extremely important. Indirect methods such as net worth analysis, bank deposit analysis, expenditure method or sources and application of funds analysis, to detect ill gotten assets, and then when ill gotten income and assets from bank stock manipulation are found, a restraining order or court order will help to recovery assets by freezing and finally confiscating them by two types of forfeiture – criminal and civil forfeitures. Establishing a code of conduct informing employees of the risks and consequences of insider trading, creating a culture of honesty and high ethics and implementing Controlled Foreign Corporation legislation to cope with off-shore companies trading, can help to recover ill gotten assets.

The paper examines if there is banks stocks manipulation around announcement of Greek national parliamentary elections during the period 2000-2009; suggesting methods to detect and recover ill gotten assets and improving the current position of the Greek economy. Findings offer important positive implications for investors, political analysts and society as a whole, as Greek banks stocks show that they are not subject to political risk and manipulation and that there are methods to detect and recover ill gotten assets. A stable bank sector is prerequisite for economy growth.
