On the complexity of collaborative cyber crime investigations
This article considers the challenges faced by digital evidence specialists when collaborating with other specialists and agencies in other jurisdictions when investigating cyber crime. The opportunities, operational environment and modus operandi of a cyber criminal are considered, with a view to developing the skills and procedural support that investigators might usefully consider in order to respond more effectively to the investigation of cyber crimes across State boundaries
Economic Causes of Deforestation in the Brazil Amazon: A Panel Data Analysis for the 2000s
We use under-explored municipality level datasets to assess the recent economic and policy determinants of deforestation in the Brazilian Amazon. We estimate yearly panel data models (from 2002 to 2009) for 457 municipalities in the region. The results show that recent deforestation is related to economic incentives, and especially to fluctuations in product (meat and soybean) prices. Moreover, we document that the increasing monitoring efforts of the Brazilian environmental police (IBAMA) were effective in reducing deforestation rates.Brazil, Amazon, deforestation
Child work and schooling under trade liberalization in Indonesia
We examine the effects of trade liberalization on child work and schooling in Indonesia. Our estimation strategy identifies geographical differences in the effects of trade policy through district and province level exposure to reduction in import tariff barriers. We use seven rounds (1993 to 2002) of the Indonesian annual national household survey (Susenas), and relate workforce participation and school enrolment of children aged 10-15 to geographic variation in relative tariff exposure. Our main findings show that increased exposure to trade liberalization is associated with a decrease in child work and an increase in enrolment among 10 to 15 year olds. The effects of tariff reductions are strongest for children from low skill backgrounds and in rural areas. However, a dynamic analysis suggests that these effects reflect the long term benefits of trade liberalization, through economic growth and subsequent income effects, while frictions and negative adjustment effects may occur in the short term.child labor, trade
Economic Causes of Deforestation in the Brazilian Amazon: A Panel Data Analysis for 2000s
We use newly launched and some never before analyzed datasets, to assess the recent economic and policy determinants of deforestation in the Brazilian Amazon. We estimate panel data models for the years between 2002 and 2007 for 368 municipalities in the region using municipality fixed effects and GMM. The results show that recent deforestation is driven by fluctuations in meat and soybean prices, it increases with rural credit availability, and with the size of rural reform settlements, while it decreases with protected areas. Moreover we find that higher presence of the Brazilian environmental police (IBAMA) was effective in reducing deforestation rates. --Deforestation,Amazon,Economic causes,Brazil
Child Labor and Trade Liberalization in Indonesia
We examine the effects of trade liberalization on child work in Indonesia. Our estimation strategy identifies geographical differences in the effects of trade policy through district level exposure to reduction in import tariff barriers. We use a balanced panel of 261 districts, based on four rounds (1993 to 2002) of the Indonesian annual national household survey (Susenas), and relate workforce participation of children aged 10-15 to geographic variation in relative tariff exposure. Our main findings show that increased exposure to trade liberalization is associated with a decrease in child work among the 10 to 15 year olds. The effects of tariff reductions are strongest for children from low skill backgrounds and in rural areas. Favorable income effects for the poor, induced by trade liberalization, are likely to be the dominating effects underlying these results.poverty, trade liberalization, child labor, Indonesia
System Estimates of Cyclical Unemployment and Cyclical Output in the 15 European Union Member-States, 1961-1999
The purpose of this paper was to estimate cyclical unemployment and cyclical output in the 15 European Union member-states using a system of Phillips curve and Okun’s law equations. Treating both the NAIRU and the potential output growth rate as time varying unobserved stochastic processes, a state-space maximum likelihood estimation method - using Kalman filter where the state variables were random walks - was followed in order to estimate the 15 systems of equations. Overall, the estimated with the new approach systems of conditional equations suggested that the extent and direction of changes of cyclical unemployment and cyclical output over the period 1961-1999 is mixed across the 15 EU member states. The paper concludes that the application of “common” policies across the 15 EU member states may be questionable because of the different expected effects of these policies on the various economies.Phillips curve, Okun’s law, Kalman filter, Cyclical unemployment, Potential output growth rate, NAIRU, Europe
Poverty, Labour Markets and Trade Liberalization in Indonesia
We measure the effects of trade liberalization over the period of 1993-2002 on regional poverty levels in 259 Indonesian regions, and investigate the labour market mechanisms behind these effects. The identification strategy relies on combining information on initial regional labour and product market structure with the exogenous tariff reduction schedule over four three-year periods. We find that poverty reduced more in regions that were more strongly exposed to import tariff liberalization. Among the potential channels behind this effect, we highlight the formalization of the unskilled labour force and structural reallocation of labour. We also show that job formation and increases in unskilled wages were related to reductions in import tariffs on intermediate goods and not to reductions in import tariffs on final outputs. These results point towards increasing firm competitiveness as a driving factor behind the beneficial poverty effects

Cryptographic Key Management in Delay Tolerant Networks (DTNs): A survey
Since their appearance at the dawn of the second millennium, Delay or Disruption Tolerant Networks (DTNs) have gradually evolved, spurring the development of a variety of methods and protocols for making them more secure and resilient. In this context, perhaps, the most challenging problem to deal with is that of cryptographic key management. To the best of our knowledge, the work at hand is the first to survey the relevant literature and classify the various so far proposed key management approaches in such a restricted and harsh environment. Towards this goal, we have grouped the surveyed key management methods into three major categories depending on whether the particular method copes with a) security initialization, b) key establishment, and c) key revocation. We have attempted to provide a concise but fairly complete evaluation of the proposed up-to-date methods in a generalized way with the aim of offering a central reference point for future research
The impact of fiscal and political decentralization on local public investments in Indonesia
We investigate the effects of the Indonesian decentralization and democratization process on budget allocation at the sub-national level. Based on panel data for 271 Indonesian districts for the years of 1994 to 2009, we address the determinants of local investment expenditures in public infrastructure in the sectors of education, health, and physical infrastructure. We find that after the dramatic expenditure decentralization of 2001, districts with relatively lower levels of public infrastructure started to invest more in these sectors. In contrast to the marked budgeting changes following the fiscal and administrative decentralization, we find no consistent effects of the democratization process on local public investments. Our results reflect initial improvements in local targeting but show no evidence of increasing electoral accountability
