Geophysics and the search of freshwater bodies: A review

Geophysics may assist scent dogs and divers in the search of water bodies for human and animal remains, contraband, weapons and explosives by surveying large areas rapidly and identifying targets or environmental hazards. The most commonly applied methods are described and evaluated for forensic searches. Seismic reflection or refraction and CHIRPS are useful for deep, open water bodies and identifying large targets, yet limited in streams and ponds. The use of ground penetrating radar (GPR) on water (WPR) is of limited use in deep waters (over 20 m) but is advantageous in the search for non-metallic targets in small ditches and ponds. Large metal or metal-bearing targets can be successfully imaged in deep waters by using towfish magnetometers: in shallow waters such a towfish cannot be used, so a non-metalliferous boat can carry a terrestrial magnetometer. Each device has its uses, depending on the target and location: unknown target make-up (e.g. a homicide victim with or without a metal object) may be best located using a range of methods (the multi-proxy approach), depending on water depth. Geophysics may not definitively find the target, but can provide areas for elimination and detailed search by dogs and divers, saving time and effort.     

Casualisation and international labour standards： The role of trade unions in Nigeria

Casualisation is a new form of work arrangement occasioned by globalisation and trade liberalisation. This development was facilitated by the technological improvements in communication and information technology. Scholars have attributed the shift from standard work arrangements to nonstandard work arrangements to the fact that employers use it to avoid the mandates and costs associated with labour laws which are designed to protect permanent employees. Casualisation became a feature of Nigerian labour market in the late 1980＇s and is traceable to the adoption of the Structural Adjustment Programme in line with the neoliberal policies prescribed by the International Monetary Fund and the World Bank. One of the effects of this policy was the retrenchment of workers in the public sector which created large scale unemployment. However, the private sector which was to be strengthened by government policies to absorb these workers could not absorb all the retrenched workers from the public sector. Therefore, many of them were employed as casual and contract workers with low remuneration, limited benefits and lack of right to organise. This development led to a ＇race to the bottom＇ of labour standards. This paper seeks to examine the adequacy of labour laws governing trade unionism in Nigeria in ensuring the right of nonstandard workers to freedom of association, as well as their conformity to international labour standards. It is argued that Nigerian labour laws are inadequate and need to be reformed in order to give protection to casual and contract workers in many sectors of the economy and to guarantee their right to unionise in order to enable them improve their rights at works.     

Characteristics of men and women completing cognitive/behavioral spouse abuse treatment

Although abuse in relationships is widespread and often escalates without intervention, the scant extant data indicate that people in abusive relationships often fail to complete treatment programs. We compared demographic characteristics, Male-Female Relations Inventory scores (MFRI), and selected MilIon Clinical Multiaxial Inventory I (MCMI-I) scale scores of men and women who did and did not complete an 8-session 4-week cognitive/behavioral group treatment program. The 16 completer men had lower scores on MCMI-I scales related to drug abuse as compared with the 18 noncompleter men. Court-referred men completed more often than other men. The 23 completer women also had lower scores on MCMI-I scales related to drug abuse than the 17 noncompleter women. Fewer of the completer women were employed and fewer had children than the noncompleter women. Scores on the MFRI were not different for completer or noncompleter men or women. Implications for interventions are discussed.     

When Equality Is not Equity:Homosexual Inclusion in Undue Influence Law

In Barclay's Bank v. O'Brien(1993) the House of Lords extended the undue influence rules to heterosexual and homosexual cohabitees, a move that was widely welcomed and has been endorsed in Royal Bank of Scotland v. Etridge (No. 2) (2001). The paper argues that the extension to homosexual couples is inappropriate, since undue influence is largely a problem of heterosexuality. It is not accidental that there have been no reported cases of undue influence between lesbian or gay partners, not because abuses of power do not occur within such relationships, but because they are free of the central causal factor of undue influence: not intimacy per se but the gendered power dynamic within heterosexual intimacy that has characterised almost all reported cases. The first part of the paper examines the courts' treatment of gay and lesbian couples in other areas of equity and concludes that the absence of gender role assumptions leads courts to treat lesbian and gay claimants more equitably than they do heterosexual women. The second part focuses on the potential for gay and, especially, lesbian relationships to act as models of more egalitarian relationships than heterosexual ones. The dominant discourse of inclusion within the gay and lesbian legal lobby is problematised, and the paper concludes that what is needed is social and judicial recognition of what is different, not what is the same, about our relationships.

Long‐term Geophysical Monitoring of Simulated Clandestine Graves using Electrical and Ground Penetrating Radar Methods: 4–6 Years After Burial

This ongoing monitoring study provides forensic search teams with systematic geophysical data over simulated clandestine graves for comparison to active cases. Simulated “wrapped,” “naked,” and “control” burials were created. Multiple geophysical surveys were collected over 6 years, here showing data from 4 to 6 years after burial. Electrical resistivity (twin electrode and ERI), multifrequency GPR, grave and background soil water were collected. Resistivity surveys revealed that the naked burial had low‐resistivity anomalies up to year four but then difficult to image, whereas the wrapped burial had consistent large high‐resistivity anomalies. GPR 110‐ to 900‐MHz frequency surveys showed that the wrapped burial could be detected throughout, but the naked burial was either not detectable or poorly resolved. 225‐MHz frequency GPR data were optimal. Soil water analyses showed decreasing (years 4 to 5) to background (year 6) conductivity values. Results suggest both resistivity and GPR surveying if burial style unknown, with winter to spring surveys optimal and increasingly important as time increases.     

Lessons Learned from Two Decades of Alternative Dispute Resolution Programs and Processes at the U.S. Environmental Protection Agency

Mediation, facilitation, and other alternative dispute resolution (ADR) techniques are being used in federal agencies, state and local governments, private-sector organizations, and among private citizens in an effort to prevent and resolve disputes in a timely, cost-effective, and less adversarial manner. The U.S. Environmental Protection Agency (EPA), one of the pioneers in the application of ADR processes and techniques to public policy disputes, recently announced that it plans to in-crease the use of ADR techniques and practices across all agency programs. This article reports the results of a four-part evaluation of the use of ADR in enforcement actions at the EPA during the last two decades. Funded by the Hewlett Foundation, this effort utilized in-depth telephone interviews, government statistics, and archival records. The four groups interviewed were EPA's alternative dispute resolution specialists, potentially responsible parties (defendants) to EPA enforcement lawsuits, mediators and facilitators to EPA cases, and agency enforcement attorneys who had participated in agency enforcement ADR processes. Concluding that there are generally high levels of satisfaction with the EPA's enforcement ADR program, this article examines the sources of obstacles and assistance to ADR efforts at the EPA, suggests ways in which the EPA might improve its ADR programs, and draws lessons from the EPA's experiences that may be helpful to other public programs or organizations.
