Overcoming the insider: reducing employee crime through Situational Crime Prevention

Information security has become increasingly important for organizations, given their dependence on ICT. Not surprisingly, therefore, the external threats posed by hackers and viruses have received extensive coverage in the mass media. Yet numerous security surveys also point to the 'insider' threat of employee computer crime. In 2006, for example, the Global Security Survey by Deloitte reports that 28% of respondent organizations encountered considerable internal computer fraud. This figure may not appear high, but the impact of crime perpetrated by insiders can be profound. Donn Parker argues that 'cyber-criminals' should be considered in terms of their criminal attributes, which include skills, knowledge, resources, access and motives (SKRAM). It is as a consequence of such attributes, acquired within the organization, that employers can pose a major threat. Hence, employees use skills gained through their legitimate work duties for illegitimate gain. A knowledge of security vulnerabilities can be exploited, utilising resources and access are provided by companies. It may even be the case that the motive is created by the organization in the form of employee disgruntlement. These criminal attributes aid offenders in the pursuit of their criminal acts, which in the extreme can bring down an organization. In the main, companies have addressed the insider threat through a workforce, which is made aware of its information security responsibilities and acts accordingly. Thus, security policies and complementary education and awareness programmes are now commonplace for organizations. That said, little progress has been made in understanding the insider threat from an offender's perspective. As organizations attempt to grapple with the behavior of dishonest employees, criminology potentially offers a body of knowledge for addressing this problem. It is suggested that Situational Crime Prevention (SCP), a relative newcomer to criminology, can help enhance initiatives aimed at addressing the insider threat. In this article, we discuss how recent criminological developments that focus on the criminal act, represent a departure from traditional criminology, which examines the causes of criminality. As part of these recent developments we discuss SCP. After defining this approach, we illustrate how it can inform and enhance information security practices. In recent years, a number of criminologists have criticised their discipline for assuming that the task of explaining the causes of criminality is the same as explaining the criminal act. Simply to explain how people develop a criminal disposition is only half the equation. What is also required is an explanation of how crimes are perpetrated. Criminological approaches, which focus on the criminal act, would appear to offer more to information security practitioners than their dispositional counterparts. Accordingly, the SCP approach can offer additional tools for practitioners in their fight against insider computer crime

Final report to BP.The Prudhoe Bay oil fields, Alaska were discovered in 1968, and commercial production commenced in 1977 with the completion of the Trans-Alaska Pipeline. Oil production has been declining since 1989, although additional exploratory drilling continues. Support facilities for oil production are built on permafrost soils that surface-thaw in summer to form extensive wetlands composed of moist meadows, sedge marshes, moist sedge-dwarf shrub tundra, grass marshes, small ponds and lakes (Walker and Acevedo 1987). To prevent thawing and subsidence of subsurface, ice-rich soils, gravel pads, 2m (6 ft) or more thickness have been built to support drilling sites as well as roads, airstrips and building pads (Kidd et al. 2006). As well sites are decommissioned, the gravel is wholly or partially removed resulting in the need for site rehabilitation and/or restoration to support wetland plants and, in some instances, enhance wildlife habitat (McKendrick 1991, Jorgenson and Joyce 1994, Kidd et al. 2004, 2006). Since the 1970s, methods to revegetate arctic wetlands have included a variety of planting techniques, seed treatments, seeding with native and non-native species (mostly grasses), and fertilizer applications (Chapin and Chapin 1980; Bishop and Chapin 1989, Jorgenson 1988, Kidd and Rossow 1998, Kidd et al. 2004, 2006, Maslen and Kershaw 1989, McKendrick 1987, 1991, 2000, McKendrick et al. 1980, McKendrick and Mitchell 1978, Mitchell et al. 1974). Treatments also have included sprigging and plug transplantation (Kidd et al. 2004, 2006), surface manipulation (Streever et al. 2003), as well as natural re-colonization (Ebersole 1987, Schwarzenbach 1996). These methods have been partially successful. The gravelly soils often are dry, nutrient-poor, and have a higher pH and lower organic matter content than surrounding soils, so natural recolonization does not occur readily (Bishop and Chapin 1989, Jorgenson and Joyce 1994). Methods such as sprigging and plug transplanting are slow, labor intensive and expensive compared to direct seeding. Fertilization, especially with phosphorus, is recommended for long-term survival of plants grown on gravelly sandy soils (BP Exploration and McKendrick 2004). Two common species in the arctic coastal wetlands are water sedge, Carex aquatilis Wahlenb. and cotton sedge, Eriophorum angustifolium Honck. Carex aquatilis in particular forms large populations that spread vegetatively by rhizomes and often dominate these wetland environments (Shaver and Billings 1975). Despite their abundance, these species have not been considered for revegetation because of poor seed germination and inadequate information on seed development and viability (Dr. William Streever, BP Alaska, pers. comm.). Both Carex and Eriophorum in arctic environments produce abundant seeds, but seed viability and germination often is low and highly variable among years and locations (Archibold 1984, Billings and Mooney 1968, Ebersole 1989, Gartner et al. 1983). Germination recommendations for both species vary by location and have included an array of pretreatments such as light, alternating temperatures, cold stratification, scarification, and high and low temperature dry storage (Amen 1966, Billings and Mooney 1960, Bliss 1958, Hunt and Moore 2003, Johnson et al. 1965, Phillips 1954 and Steinfeld 2001). The purpose of this project was to explore methods of seed germination of Carex aquatilis and Eriophorum angustifolium, to learn the conditions for germination and dormancy control mechanisms, and identify seed treatments that might enhance germination for eventual use in direct-seeding or plug production for arctic wetland revegetation

Preparations for Independence and Financial Security in Later Life: A Conceptual Framework and Application to Canada

In this paper, we develop a conceptual framework to describe an individual's preparations for later life. Situated in the life course perspective, this provides a framework that invites a more comprehensive and systematic study of preparations for later life. It describes a dynamic process that portrays the interplay between social structure and human agency. Through its consideration of collective preparations (the public protection programs offered by the state), individual preparations (financial and non- financial), and the interplay between the two, this framework provides fresh insight into the existing literature on retirement planning, the timing of retirement, savings, and consumption behaviour in later life. Moreover, the model may be used to structure research questions, to guide policy decision making and to point the direction for the design and content of future research studies. While the purpose of this paper is primarily the development of a conceptual model, we draw on empirical examples from the 1991 Survey of Aging and Independence (SAI) to illustrate some aspects of the model to Canada. We conclude by suggesting a number of research and questions that may be generated from the model.retirement planning; savings; SAI

Evaluating Unpaid Time Contributions by Seniors: A Conceptual Framework

In the past, considerable research in gerontology has focused on services provided to seniors. Recently, however, there has a been a growing recognition of the contributions made by seniors to their families, communities and to society. Empirical estimates have been provided by researchers to show how much these contributions are worth in terms of savings in dollar amounts. A critical review of the literature identifies unresolved issues concerning which contributions to count and how to measure and value these contributions. As yet, no clear criteria exist that readily identify the distinction between volunteer activities and unpaid work, what specifically should be counted as an unpaid time contribution, how it should be quantified, and how this unit of contribution should be monetarily valued. The market replacement approach and the opportunity cost approach that are used to assign value to unpaid work often use very different wage rates or levels of income loss. This paper reviews the relevant literature and identifies important issues in evaluating unpaid time contribution of seniors. The authors propose a framework which addresses some of the methodological shortcomings identified in previous research and which provides a guide for future research in this area.seniors; valuing unpaid work

Care of the chronic, non-acutely ill elderly person in acute hospitals in light of the biomedical science approach

The purpose of this study was to investigate aspects and specific events of health care intervention techniques rendered to chronic, non-acutely ill elderly patients, (henceforth known as CNIE), while in an acute care hospital. The patients' own perceptions were sought to ascertain if the care given was patient-centred or more characteristic with the traditional biomedical science approach (BMS). This latter approach, according to many researchers, remains the primary mode of hospital health care intervention. The BMS approach is described by sociologists and others as a health care strategy that is overly cure oriented rather than care oriented. It is impersonal, objective, and dualistic - the very opposite of a patient-centred approach. Using a patientcentred care survey to carry out empirical research, I set out to ascertain, at a local level, the extent and degree a BMS approach existed within Thunder Bay's three acute care hospitals. The sample included 32 participants who were or remain heavy users of health services. These individuals were either waiting for placement or recently placed into another care facility. At the time of the interview, qualified participants were located either in one of three Thunder Bay acute care hospitals, a private nursing home, one of two city Homes for the Aged, or in their own home. All shared their perceptions of the care they received while in hospital. CNIE patient demographic characteristics - sex, age, marital status, length of present hospitalization, former occupation, mother tongue, hospital recently treated at and reason for hospitalization - were documented. Six care indices were embodied in the patient-centered survey. These included Communication, Education, Emotional Support, Patient Needs and Preferences, Consistency of Quality of Care and Physical Comfort. Descriptive statistics were used for analysis of the results. Based on the comments obtained from the CNIE population sample, findings suggest that, although present or former patients were satisfied overall with the care they received while in an acute care hospital, there are particular reported problems in different domains of the care rendered to them which are congruent with characteristics/aspects of the traditional biomedical science approach. Results also suggest that the need for a paradigm shift - from a solely objective, rational and impersonal approach (vis a vis a biomedical science orientation) to a more biopsychosocial-like approach, (a "revolution” in the Kuhnian sense of the term), may not be as monumental a task as some researchers would suggest. Recommendations for further research are made

Microarray screening of Guillain-Barré syndrome sera for antibodies to glycolipid complexes

Objective: To characterize the patterns of autoantibodies to glycolipid complexes in a large cohort of Guillain-Barré syndrome (GBS) and control samples collected in Bangladesh using a newly developed microarray technique. Methods: Twelve commonly studied glycolipids and lipids, plus their 66 possible heteromeric complexes, totaling 78 antigens, were applied to polyvinylidene fluoride–coated slides using a microarray printer. Arrays were probed with 266 GBS and 579 control sera (2 μL per serum, diluted 1/50) and bound immunoglobulin G detected with secondary antibody. Scanned arrays were subjected to statistical analyses. Results: Measuring antibodies to single targets was 9% less sensitive than to heteromeric complex targets (49.2% vs 58.3%) without significantly affecting specificity (83.9%–85.0%). The optimal screening protocol for GBS sera comprised a panel of 10 glycolipids (4 single glycolipids GM1, GA1, GD1a, GQ1b, and their 6 heteromeric complexes), resulting in an overall assay sensitivity of 64.3% and specificity of 77.1%. Notable heteromeric targets were GM1:GD1a, GM1:GQ1b, and GA1:GD1a, in which exclusive binding to the complex was observed. Conclusions: Rationalizing the screening protocol to capture the enormous diversity of glycolipid complexes can be achieved by miniaturizing the screening platform to a microarray platform, and applying simple bioinformatics to determine optimal sensitivity and specificity of the targets. Glycolipid complexes are an important category of glycolipid antigens in autoimmune neuropathy cases that require specific analytical and bioinformatics methods for optimal detection

A Lovelock black hole bestiary

We revisit the study of (A)dS black holes in Lovelock theories. We present a new tool that allows to attack this problem in full generality. In analyzing maximally symmetric Lovelock black holes with non-planar horizon topologies many distinctive and interesting features are observed. Among them, the existence of maximally symmetric vacua do not supporting black holes in vast regions of the space of gravitational couplings, multi-horizon black holes, and branches of solutions that suggest the existence of a rich diagram of phase transitions. The appearance of naked singularities seems unavoidable in some cases, raising the question about the fate of the cosmic censorship conjecture in these theories. There is a preferred branch of solutions for planar black holes, as well as non-planar black holes with high enough mass or temperature. Our study clarifies the role of all branches of solutions, including asymptotically dS black holes, and whether they should be considered when studying these theories in the context of AdS/CFT.Comment: 40 pages, 16 figures; v2: references added and minor amendments; v3: title changed to improve its accuracy and general reorganization of the results to ameliorate their presentatio

Who's minding the shop? The role of Canadian research ethics boards in the creation and uses of registries and biobanks

<p>Abstract</p> <p>Background</p> <p>The amount of research utilizing health information has increased dramatically over the last ten years. Many institutions have extensive biobank holdings collected over a number of years for clinical and teaching purposes, but are uncertain as to the proper circumstances in which to permit research uses of these samples. Research Ethics Boards (REBs) in Canada and elsewhere in the world are grappling with these issues, but lack clear guidance regarding their role in the creation of and access to registries and biobanks.</p> <p>Methods</p> <p>Chairs of 34 REBS and/or REB Administrators affiliated with Faculties of Medicine in Canadian universities were interviewed. Interviews consisted of structured questions dealing with diabetes-related scenarios, with open-ended responses and probing for rationales. The two scenarios involved the development of a diabetes registry using clinical encounter data across several physicians' practices, and the addition of biological samples to the registry to create a biobank.</p> <p>Results</p> <p>There was a wide range of responses given for the questions raised in the scenarios, indicating a lack of clarity about the role of REBs in registries and biobanks. With respect to the creation of a registry, a minority of sites felt that consent was not required for the information to be entered into the registry. Whether patient consent was required for information to be entered into the registry and the duration for which the consent would be operative differed across sites. With respect to the creation of a biobank linked to the registry, a majority of sites viewed biobank information as qualitatively different from other types of personal health information. All respondents agreed that patient consent was needed for blood samples to be placed in the biobank but the duration of consent again varied.</p> <p>Conclusion</p> <p>Participants were more attuned to issues surrounding biobanks as compared to registries and demonstrated a higher level of concern regarding biobanks. As registries and biobanks expand, there is a need for critical analysis of suitable roles for REBs and subsequent guidance on these topics. The authors conclude by recommending REB participation in the creation of registries and biobanks and the eventual drafting of comprehensive legislation.</p

Nature of Sonoluminescence: Noble Gas Radiation Excited by Hot Electrons in "Cold" Water

We show that strong electric fields occurring in water near the surface of collapsing gas bubbles because of the flexoelectric effect can provoke dynamic electric breakdown in a micron-size region near the bubble and consider the scenario of the SBSL. The scenario is: (i) at the last stage of incomplete collapse of the bubble the gradient of pressure in water near the bubble surface has such a value and sign that the electric field arising from the flexoelectric effect exceeds the threshold field of the dynamic electrical breakdown of water and is directed to the bubble center; (ii) mobile electrons are generated because of thermal ionization of water molecules near the bubble surface; (iii) these electrons are accelerated in ''cold'' water by the strong electric fields; (iv) these hot electrons transfer noble gas atoms dissolved in water to high-energy excited states and optical transitions between these states produce SBSL UV flashes in the trasparency window of water; (v) the breakdown can be repeated several times and the power and duration of the UV flash are determined by the multiplicity of the breakdowns. The SBSL spectrum is found to resemble a black-body spectrum where temperature is given by the effective temperature of the hot electrons. The pulse energy and some other characteristics of the SBSL are found to be in agreement with the experimental data when realistic estimations are made.Comment: 11 pages (RevTex), 1 figure (.ps

Pharmaceuticals and the Elderly: A Comparative Analysis

This paper compares and contrasts outpatient pharmaceutical policies for the elderly in seven OECD nations: Australia, Canada, Germany, Japan, New Zealand, the United Kingdom, and the United States. Each country is facing an increasing financial burden due to rapidly growing numbers of elderly citizens, in number and as a percentage of population, and rising drug costs. As a result, they are struggling to balance varying levels of commitment to providing drugs for the elderly with the need to contain costs. Although each country\u27s healthcare system is unique, the methods that each country is using to control rising pharmaceutical costs are similar. Many countries are gravitating toward the use of last-dollar rather than first-dollar coverage. All provide inpatient pharmaceutical coverage
