University ‘Pay-for-grades’: the bait and switch search engine optimization strategies of contract cheating websites in the United States

This paper presents the first systematic investigation into the search engine optimization practices of major contract cheating websites in the United States. From a business perspective, visibility in organic search engine results is considered one of the top client recruitment tools. The current understanding of student recruitment strategies by these companies remains largely unexplored in both academic literature and popular press. Replicating the business research practices used in the search engine optimization industry, comprehensive search engine ranking and traffic data was obtained for the 38 largest contract cheating websites in the US. The overall objective was to illuminate the strategies that these companies take to get their services at the top of the search results of as many students as possible – not just the relatively small proportion of students actively cheating. The results show that these companies dominate the search results for not just students searching to cheat, but also for naïve search efforts, when students are simply doing genuine research or classwork. These nefarious companies use highly sophisticated search engine manipulation strategies to bait naïve student searchers onto their sites, thus enabling the potential to switch them to cheaters. Higher education institutions, armed with the specific details provided in this study, can use the strategies outlined in the discussion to directly and negatively impact on the success of these contract cheating services

Feeding ecology, residency patterns and migration dynamics of bull sharks (Carcharhinus leucas) in the southwest Indian Ocean

Bull sharks (Carcharhinus leucas) are globally distributed top predators that play an important ecological role within coastal marine communities. However, little is known about how the spatial and temporal scales of their habitat use are associated with their ecological role. In this study, a population of sub-adult and adult bull sharks were investigated within a remote subtropical marine community in the southwest Indian Ocean off the coast of southern Mozambique. The main objectives of the study were to test a minimally invasive remote biopsy sampling method; to investigate the feeding ecology of bull sharks; and to investigate the temporal and spatial scales of bull shark residency patterns and migration dynamics. Biopsy tests on free-swimming bull sharks showed that the devised sampling technique provided a minimally invasive and consistent method (biopsy retention rate = 87%) to obtain muscle tissue samples sufficiently large enough (310±78mg, mean ± SD) for stable isotope analysis. Results from the stable isotope analysis showed that adult bull sharks appeared to exhibit a shift towards consistentlyhigher trophic level prey from an expanded foraging range compared to sub-adults, possibly due to increased mobility linked with size. Additionally, bull sharks had significantly broader niche widths compared to top predatory teleost assemblages with a wide and enriched range of δ13C values relative to the local marine community, suggesting that they forage over broad spatial scales along the east coast of southern Africa. Results from the passive acoustic telemetry investigation, conducted over a period between 10 and 22 months, supported these findings showing that the majority of tagged adult sharksexhibited temporally and spatially variable residency patterns interspersed with migration events. Ten individuals undertook coastal migrations that ranged between 433 and 709km (mean = 533km) with eight of these sharks returning to the study site. During migration, individuals exhibited rates of movement between 2 and 59km.d-1 (mean = 17.58km.d-1) and were recorded travelling annual distances of between 450 and 3760km (mean = 1163km). These findings suggest that adult bull sharks are not the sedentary species once thought to be but rather, consistently move over broad spatial scales on the east coast of southern Africa and play an important predatory role shaping and linking ecological processes within the southwest Indian Ocean

Impacts of international trade policy on fisheries-dependent coastal communities: a Newfoundland case study

This thesis examines how international trade policy impacts fisheries and local fishing communities. The case study for the research is the Canada-European Union (EU) Comprehensive Economic and Trade Agreement (CETA), which came into effect in 2017. The study region is the Great Northern Peninsula (GNP), on the northwest coast of Newfoundland, Canada, where fishing communities depend on the export-oriented fisheries. By means of interactive governance theory, an institutional analytical approach is employed to examine the change in the fisheries and the governing system that CETA may bring, as well as the compatibility between the policies and principles of CETA with those governing the case-study region. Subsequently, informant interviews were conducted with fish harvesters, community members, and local and provincial governments to gauge initial responses to CETA and the change that it has already induced. Results indicate that CETA impacts governing interactions in the case-study region by first, expanding market access, and second, by weakening regionally specific protections of the inshore fishery. Furthermore, initial responses show that current stressors facing the region, including lack of adequate resource access and processing sector vulnerability, may be exacerbated, rather than mitigated, by CETA. This research highlights the importance of an early appraisal of the overall impact of trade policy from the governance perspective and according to local communities that are directly and indirectly affected by such policy. Specifically, the research offers: (1) a methodological approach to assess international trade policy through a governance lens; (2) an illustration of interactions between international trade and coastal communities; and (3) a broadening of discussion about implications of the seafood trade and international trade policy at all levels

An Investigation into Seasonal Trends of Terpene Emissions from Biogenic Sources: A Focus on Monoterpene and Sesquiterpene Emissions of Native Colorado Tree Species

Plants naturally emit a variety of highly reactive hydrocarbon compounds, classified as biogenic volatile organic compounds (BVOC), which are known to have large implications for atmospheric chemistry. Once released into the troposphere, BVOC participate in reactive nitrogen, hydroxyl and ozone chemistry as well as secondary organic aerosol formation. The resulting air quality impacts warrant a thorough understanding of BVOC emission behavior, critical for effective regional modeling and legislative decision-making. This work aims to improve the database and algorithms used in biogenic emission models by examining the seasonal trends of two classes of BVOC, monoterpene (MT) and sesquiterpene (SQT) hydrocarbons. A field site established at a local tree nursery provided an opportunity to easily monitor the emissions of naturally growing vegetation throughout a growing season. The emission rates of five tree species native to Colorado forests were measured monthly between February 2009 and February 2010. Biogenic emissions were found to exhibit seasonal variation with higher emission rates observed between spring and late summer, falling to a low through winter months. The seasonal behavior of BVOC emissions proves to be very complex. These findings are discussed and call into question the methods used for estimating annual emission rates

Stakeholder’s experiences of living and caring in technology-rich supported living environments for tenants living with dementia

We are grateful to our peer-researchers for their time and commitment to the TESA-DRI project. The project was funded by the Health and Social Care Research and Development Division Public Health Agency and Atlantic Philanthropies (COM/4955/14).Background: Technology innovation provides an opportunity to support the rising number of people living with dementia globally. The present study examines experiences of people who have dementia and live in technology enriched supported care models. Additionally, it explores caregiver’s attitudes towards technology use with the housing scheme. Methods: A qualitative research design was adopted, and eight housing schemes consented to take part in the study. A technology audit was undertaken in addition to participant interviews and caregiver survey. Seven peer researchers conducted semi-structured interviews with 22 people living with dementia. Interviews were analysed using thematic analysis. Informal and formal caregivers were invited to complete a survey to capture their attitudes towards technology use. A total of 20 informal and 31 formal caregiver surveys were returned. All surveys were input into Survey Monkey and downloaded into excel for analysis. Closed questions were analysed using descriptive statistics and open-ended questions were organised into themes and described descriptively. Results: The technology audit identified that technologies were in place from as early as 2002. Technology heterogeneity of, both passive and active devices, was found within the housing schemes. Technologies such as wearable devices were reportedly used according to need, and mobile phone use was widely adopted. The themes that developed out of the tenant interviews were: Attitudes and Engagement with Technology; Technology Enhancing Tenants Sense of Security; Seeking Support and Digital Literacy; and Technology Enabled Connection. A lack of awareness about living alongside technology was a major finding. Technologies enabled a sense of reassurance and facilitated connections with the wider community. The interaction with technology presented challenges, for example, remembering passwords, access to Wi-Fi and the identification of its use in an emergency. The caregiver survey reported a range of facilitators and barriers for the use of technology within care. Both types of caregivers held relatively similar views around the benefits of technology, however their views on issues such as privacy and consent varied. Safety was considered more important than right to privacy by family caregivers. Conclusions: The present study provides new insight into stakeholder’s experiences of living, working and caregiving alongside technology in supported living environments. As the generation of people living with dementia become more tech savvy, harnessing everyday technologies to support care could enable holistic care and support the transition through the care continuum. Advance care planning and technology assessments are at the very core of future technology provision. It is evident that a paternalistic attitudes towards technology use could impact the multitude of benefits technology can play in both health and leisure for people living with dementia and their caregivers.pubpu

Wireless impact sensing headband - W.I.S.H.

The prevalence of undiagnosed head injuries in the athletic world, and their associated health risks, is too great to ignore. This is especially true in non-helmeted sports where the availability of impact monitoring technologies is few and far between. In this paper, we discuss our wireless impact sensing headband technology that aids in the awareness and detection of potential concussions, from inception through design completion. Through the use of a custom-built validation system capable of simulating impact collisions, along with a series of experiments and revisions, our team was able to build a device that can sense and transmit data throughout the majority of the impact range of standard concussions. This system has the potential to help millions of athletes around the world be much better prepared in the event of a potentially life-threatening head impact. However, while our system is able to accurately detect and transmit impact data in real time, we found that additions such as the ability to sample at a much higher rate than experimented with, a more ergonomic design, and a lightweight, durable enclosure would be needed in order for our product to be a viable mass-market competitor. Although the product is not ready for the mass market as of today, it will be a vital part to larger systems used for predictive analytics and more innovative and robust athletic game strategy

Partnering with older people as peer researchers

Brendan McCormack - ORCID: 0000-0001-8525-8905 https://orcid.org/0000-0001-8525-8905Background: The term peer researcher describes the role of a person who has similar characteristics and can identify with the participant group in a research study. This paper describes the methodological approach and experiences of older people who were peer researchers on a study that explored the lived experience of people with dementia who lived in technology-enriched housing.Methods: Nine people responded to a public recruitment campaign through nongovernment organisations using multiple methods such as seniors' forums, development officers and social media. Mandatory training across 2 days was provided and seven peer researchers successfully completed the training. A total of 22 interviews were undertaken by the seven peer researchers. The data collected from the training feedback proforma (N = 7), interview debrief forms (N = 22) and final evaluation forms (N = 5) were analysed using content analysis and triangulated.Results: Five core themes emerged from the data using a content analysis approach to examine the peer researchers' experience: (1) skill development; (2) recognition of competencies; (3) connection; (4) supplementary information; and (5) the triad dynamic.Conclusions: Considerations to enhance the peer researcher experience emerged including enhanced communication training, consideration of the optimum number of peer researchers to balance workload and identification of the characteristics that enable people to connect as peer researchers. Future research should consider the impact that experiential skill development has on the data collected.Public Contribution: Older people conducted qualitative interviews as peer researchers with people living with dementia to cocreate knowledge.Health and Social Care Research and Development Division Public Health Agency and Atlantic Philanthropies, Grant/Award Number: COM/4955/14https://doi.org/10.1111/hex.1333124pubpub

Review article: the effects of antitumour necrosis factor-α on bone metabolism in inflammatory bowel disease.

BACKGROUND: Patients with inflammatory bowel disease (IBD) are at increased risk of osteoporosis. A number of studies have emerged in recent years indicating that tumour necrosis factor (TNF) blockade appears to have a beneficial effect on bone mineral density (BMD) in IBD patients. AIMS: To provide a review of the available data regarding the effect of the currently licensed anti-TNF-α therapies on bone metabolism and BMD in IBD patients. METHODS: A Medline search was performed using the search terms \u27infliximab\u27, \u27bone metabolism\u27, \u27IBD\u27, \u27BMD\u27, \u27bone markers\u27, \u27adalimumab\u27, \u27bone disease\u27, \u27Crohn\u27s disease\u27 and \u27ulcerative colitis\u27. RESULTS: Infliximab has a beneficial effect on bone turnover markers in Crohn\u27s disease (CD) patients in the short term. The longest study to date comprising 24 CD patients showed an overall improvement in two bone formation markers - b-alkaline phosphatase (P = 0.022) and osteocalcin (P = 0.008) at 4 months post-treatment. Moreover, the largest study to date comprising 71 CD patients showed significant improvement in sCTx, a bone resorption marker (P = 0.04) at week-8 post-treatment. There is little data looking at the effect of anti-TNF-α therapy on bone metabolism in ulcerative colitis. Moreover, the long-term effects of anti-TNF-α therapy on bone structure and fracture risk in IBD patients are currently not known. The effect of cessation of anti-TNF-α therapy on bone metabolism is also unknown. CONCLUSION: Properly controlled long-term trials are needed to fully evaluate the impact of TNF blockade on bone mineral density
