    Child work and schooling under trade liberalization in Indonesia

    Get PDF
    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

    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

    Get PDF
    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 Labor and Trade Liberalization in Indonesia

    Get PDF
    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

    Economic Causes of Deforestation in the Brazilian Amazon: A Panel Data Analysis for 2000s

    Get PDF
    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

    The Status of the Third Party Confession in Virginia: In Search of a Trustworthiness Standard

    Get PDF
    The issue of third party confessions generates great controversy. The basic inquiry is, should confessions allegedly uttered by persons other than the defendant be admitted into evidence in a criminal trial? If so, under what conditions? How much discretion should a trial judge be afforded in determining whether this evidence should be admitted to exculpate a person charged with murder, armed robbery, or rape? Should the trial judge or the jury determine the reliability of the witness, the declarant, or the content of the confession itself? These considerations, in addition to due process arguments, have troubled criminal courts, legislators, and recently the Supreme Court of Virginia in Ellison v. Commonwealth

    Opportunistic Key Management in Delay Tolerant Networks

    Get PDF
    Key Management is considered to be a challenging task in Delay Tolerant Networks (DTNs) operating in environments with adverse communication conditions such as space, due to the practical limitations and constraints prohibiting effective closed loop communications. In this paper we propose opportunistic key management as a more suitable solution for key management in networks requiring opportunistic behaviour. We show that opportunistic key management is better exploited and utilized when used in conjunction with routing decisions by security aware DTN nodes

    DHP Framework: Digital Health Passports Using Blockchain - Use case on international tourism during the COVID-19 pandemic

    Get PDF
    In order to contain the COVID-19 pandemic, several countries enforced extended social distancing measures for several weeks, effectively pausing the majority of economic activities. In an effort to resume economic activity safely, several Digital Contact Tracing applications and protocols have been introduced with success. However, DCT is a reactive method, as it aims to break existing chains of disease transmission in a population. Therefore DCT is not suitable for proactively preventing the spread of a disease; an approach that relevant to certain use cases, such as international tourism, where individuals travel across borders. In this work, we first identify the limitations characterising DCT related to privacy issues, unwillingness of the public to use DCT mobile apps due to privacy concerns, lack of interoperability among different DCT applications and protocols, and the assumption that there is limited, local mobility in the population. We then discuss the concept of a Health Passport as a means of verifying that individuals are disease risk-free and how it could be used to resume the international tourism sector. Following, we present the DHP Framework that uses a private blockchain and Proof of Authority for issuing Digital Health Passports. The framework provides a distributed infrastructure supporting the issuance of DHPs by foreign health systems and their verification by relevant stakeholders, such as airline companies and border control authorities. We discuss the attributes of the system in terms of its usability and performance, security and privacy. Finally, we conclude by identifying future extensions of our work on formal security and privacy properties that need to be rigorously guaranteed via appropriate security protocols

    SSD: New Challenges for Digital Forensics

    Get PDF
    ICT changes continuously and we are used to look at IT in a slightly dif-ferent way every year. Things are developed and manufactured to be smaller and faster but few changes are truly technologically revolutionary. Some changes creep up on us as they arrive under cover of previously known technology. Solid State Disks (SSD) is such a technology. The use of SSD is simple enough and for many purposes it can be used as if it was a normal hard disc but many times faster and with a very much lower power consumption. But, SSD is not an evolution of hard disc technology, it is a completely new technology which imitates the behav-iour of a hard disc. There are major underpinning differences which have serious consequences for security and for digital forensic. Due to how the SSDs work it is not always certain that deleted data are purged from the disc. On the other hand SSD‟s can sometimes purge data all by themselves even if they are not connected to any interface with only the power on. This means that normal guidelines aimed at hard discs for how to preserve digital forensic evidence are not just inappropri-ate but could if followed result in potential evidence being lost, destroyed or deemed unvalid as evidence. This paper gives an overview of some of the princi-pal and unexpected challenges that SSDs have brought with them for Digital Fo-rensics investigations
