    Get PDF
    © 2018 Journal of Innovation & Knowledge The Middle East, as a region, contributes proportionally less to new knowledge generation than other parts of the world. The United Arab Emirates (UAE) has sought to correct this imbalance through efforts to promote a knowledge-based economy and through educational investment. In light of these advances, significant challenges still remain in the promotion and production of high quality research in the social sciences, including business. The current monograph highlights the vital importance of such research to the social and economic development of the UAE. Reflecting on nearly a decade of conducting research in the UAE with varying degrees of success the authors highlight critical incidents, experiences and observations which serve to illustrate the challenges of new knowledge creation in the business and social sciences. Discussions focus on identifiable barriers to high quality research at both the micro and macro levels, within and outside the UAE, with specific recommendations on how such barriers can be overcome

    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

    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 Ύ13C 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

    The trophodynamics of the numerically dominant mesozooplankton (200-2000 m) in the vicinity of the Subtropical Convergence (STC) in the Indian sector of the Southern Ocean during austral autumn (April / May) 2007 were investigated as part of the Southern Ocean Ecosystem Variability Study. The survey consisted of six north-south transects each bisecting the STC between 38Âș to 43ÂșS and 38Âș to 41Âș45’E. In total, 48 stations situated at 30 nautical mile intervals were occupied over a period of ten days. Hydrographic data revealed a well defined surface and sub-surface expression of the STC, which appeared to meander considerably between 41ÂșS and 41Âș15’S. Surface chlorophyll-a (chla) concentrations were low, ranging between 0.08 and 0.68 mg chl-a.m-3 and were generally dominated by the picophytoplankton (0.05). Total integrated mesozooplankton abundance and biomass during the study ranged between 3934.9 and 308521.4 ind.m-2 (mean = 47198.19; SD±62411.4 ind.m-2) and between 239.8 and 4614.3 mg Dwt.m-2 (mean = 1338.58; SD ±1060.5), respectively. Again, there were no significant spatial patterns in the total mesozooplankton abundance or biomass within the region of study (p>0.05). No significant correlations were found between biological (chlorophyll-a concentrations and zooplankton abundance) and physico-chemical variables (temperature and salinity) (p>0.05). The total mesozooplankton community was numerically dominated by copepods of the genera Pleuromamma, Calanus, Oncaea and Oithona. Other important representatives of the mesozooplankton community included the tunicate, Salpa thompsoni, and the pteropod, Limacina retroversa. At the 40% similarity level, numerical analysis identified five distinct mesozooplankton groupings within the survey area. Differences between the groupings were associated with changes in the relative contribution of numerically dominant species rather than the presence or absence of individual species. No groupings were associated with any specific feature of the front within the survey area. The feeding rates of the six most numerically abundant mesozooplankton species (Calanus simillimus, Limacina retroversa, Pleuromamma abdominalis, Clausocalanus breviceps, Oncaea conifera, Salpa thompsoni) accounting for on average 39% of the total mesozooplankton counts, were investigated using the gut fluorescence technique. For all species, the total gut pigment contents during the night time were significantly higher than the daytime values (p60%) was typically associated with those stations where the pteropod, L. retroversa, and the tunicate, S. thompsoni, contributed more than 5% of the total mesozooplankton counts. No significant differences were found in the grazing impact of any or all selected species situated either north, south or in the immediate vicinity of the front (p>0.05 in all cases). The lack of defined spatial patterns in the mesozooplankton abundance and community structure suggests that the STC did not act as a significant biogeographic barrier to the distribution of mesozooplankton during the study. It is presumed that the large scale mixing event caused by a storm prior to this study was responsible for the observed lack of elevated biological activity within the region of the STC

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

    Get PDF
    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

    From Springer Nature via Jisc Publications RouterHistory: received 2021-12-22, registration 2023-01-12, accepted 2023-01-12, pub-electronic 2023-02-01, online 2023-02-01, collection 2023-12Publication status: PublishedAcknowledgements: Acknowledgements: We would like to acknowledge the wider research team that worked within the TESA-DRI Project. 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
