Empirical Evidence on Human Trafficking and Migration-Debt Contracts in Bangladesh

Abstract

This article presents an analysis of the payments illegal migrants make to traffickers. It covers the total amounts of these payments, the incidence of migration-debt (or shared) contracts, and the value of the deferred payment component under these shared contracts. Data on illegal migrants from three field surveys conducted in Bangladesh from April 2009 to November 2010 are used. The results show that the total payments made to traffickers vary with easily observed characteristics (gender, age, marital status) but do not vary with details of the migration process (training provided, time spent in the trafficker’s queue). These relationships are consistent with exploitation. Migration-debt contracts are more prevalent when the costs of illegal migration are relatively high, which adds empirical support to theoretical models such as Friebel and Guriev (2006). Contrary to existing reports, we document variations in fees for illegal passage across individuals.     

Tax Evasion and the Role of the State Actor(s) in Bangladesh

Little attention has been paid to tax evasion in developing countries due to a lack of data. This article addresses this lacuna by investigating the tax evasion practices and finds significant increases in tax evasion in Bangladesh. The study makes a major contribution to the literature in tax evasion, and indicates that the norms of state actor(s) (i.e. the National Board of Revenue–the sole tax authority in Bangladesh) lie in the interests of politicians and the continuation of corruption. The legitimacy of the state actors in this case means that they act as facilitators for increasing tax evasion practices. Therefore, the current system has endured remarkably robustly to date, and coercive isomorphism is indeed needed in the institutionalization process.     

Causes of the US Hostage Crisis in Iran: The Untold Account of the Communist Threat

This article provides a revisionist account of the occupation of the US embassy in Tehran in November 1979, one of the most conspicuous manifestations of anti-Americanism in recent history. Drawing solely upon primary documents, largely from various Iranian communists and Islamists, it questions the conventional wisdom that the Islamists' takeover of the embassy was a grassroots reaction to American policies, particularly after President Carter admitted the ailing Shah. It also challenges the argument that the radical students stormed the embassy primarily to bring down the nationalist provisional government. Instead, I introduce a critical overlooked factor and argue that the Hostage Crisis can be better explained as a preemptive act by the Islamists to outbid the leftists' anti-American activities. I demonstrate that the United States and the Islamists were seeking to maintain normal relations during and even after the 1979 revolution. However, various communist organizations that surfaced after the revolution posed an existential threat to the new Islamist-nationalist government, quickly dominating universities, labor unions, and intellectual circles throughout the country and accusing the Islamists and their nationalist allies of collaborating with the United States. In this climate, the Islamists strategically adopted the Left's anti-imperialist language and eventually occupied the US embassy to establish their anti-American credibility.     

Thermal requirements of immature stages of Chrysomya albiceps (Diptera: Calliphoridae) as a common forensically important fly

Entomological material may be used to estimate the time since death occurred (postmortem interval, PMI) in forensically obscure cases. The method that is commonly used to calculate minimum post-mortem interval (mPMI, i.e., the least amount of time since one can be confident death occurred) is based on the relationship between insect development and ambient temerature. Isomegalen and isomorphen diagrams are among methods allowing to calculate the age of necorphagous insects, yet thermal summation models provide the most precise and acurate estimations. The digrams are prepared based on the length or the developmental stages of the larvae as a function of time and mean ambient temperature. A knowledge of thermal requirements, in particular lower temperature threshold (D_z) at which development of a species terminates, is of essential importance to calculate ADD (Accumulated Degree Days). In this study different temperature regimes were used to construct the isomorphen diagram, examinate changes in larval body length at different ambient temperatures and to estimate the thermal requirements for developemnt of Chrysomya albiceps, the most common dipteran species reported on human and animal cadavers in Iran. Six development events including hatching, 1st ecdysis, 2nd ecdysis, wandering, pupariation and eclosion were studied under eleven constant temperature regims (17–37 ⁰C). The development rate of Ch. albiceps increased as temperature increased. The larval length peaked at the end of third stage and then decreased at wandering stage. The maximum larval length occurred at 72 h post oviposition at either 31, 33, or 35 °C. At 17 °C, larvae did not hatch from eggs and at 37 °C wandering larvae did not proceed to pupariation, and thus larval development were analysed at the nine left over temperatures. The development stages required at least (D_z ± SE) 13.04 ± 0.37, 14.29 ± 0.45, 15.69 ± 0.56, 15.18 ± 0.56, 14.94 ± 0.48, and 11.23 ± 0.41 °C to reach one of the successive developmentl events, respectively. The estimated thermal summation constant (k) for those the six events were 10.43 ± 0.27, 19.31 ± 0.32, 27.87 ± 1.3, 55.94 ± 1.82, 66.69 ± 3.5, and 143.52 ± 5.61 ADD accordingly.     

关于孟加拉国卡西族社会经济特点的研究

本文提供了关于孟加拉国卡西族的原始资料。此项研究目的在于揭示孟加拉国卡西族的社会经济特点和其家庭的生活水平。锡尔赫特地区中两块区域被选作此次研究的试验地。每个区域中共有 4 0个家庭被调查取样。结果显示 38%的家庭没有自已的土地 ,其中只有7%的家庭是大家庭。绝大多数的小农场主和他的家庭成员都没受过正式的教育。卡西族人家庭主要从事的都是农业 ,并且生活水平都不高。有一些卡西族人家庭是从商的。他们面临着不少问题 ,不断增加的政府发展计划正逐渐改善他的生活水平。
