Optimization of orbital assignment and specification of service areas in satellite communications

The mathematical nature of the orbital and frequency assignment problem for communications satellites is explored, and it is shown that choosing the correct permutations of the orbit locations and frequency assignments is an important step in arriving at values which satisfy the signal-quality requirements. Two methods are proposed to achieve better spectrum/orbit utilization. The first, called the delta S concept, leads to orbital assignment solutions via either mixed-integer or restricted basis entry linear programming techniques; the method guarantees good single-entry carrier-to-interference ratio results. In the second, a basis for specifying service areas is proposed for the Fixed Satellite Service. It is suggested that service areas should be specified according to the communications-demand density in conjunction with the delta S concept in order to enable the system planner to specify more satellites and provide more communications supply

Empowering Students of Color to Study Abroad: Effective Approaches for Predominantly White Institutions

Traditionally studying abroad is an opportunity afforded to college students. For many, it is perceived as a desirable and essential component to the college experience. Initially developed by a white professor for white students at a predominantly white institution (PWI) to immerse themselves in European culture. The study abroad model in higher education was not designed with inclusivity in mind. However, research suggests that access to such opportunities depends on a student’s network to include: social, cultural, and financial capital as well as the university’s investment in empowering students to participate in study abroad programs. Historically, government funded initiatives have sought to increase the number of students studying abroad, and more recently enhancing the participation of students of color. Studies imply that accessibility and awareness for all college students is not equal. This study uses the community cultural wealth framework and transformative learning theory to explore how students of color attending a PWI perceive study abroad programs and how enhanced support, awareness, and targeted marketing can improve their participation in study abroad opportunities. Ultimately, inclusive marketing on PWI campuses will assist in dispelling the stereotypical images and thoughts associated with studying abroad

Implementing Service Innovations in European Hotels

This paper examines the impact of postadoption innovation implementation strategies on five distinct performance outcomes. Using a sample of 85 hotels in Europe, the study explores which implementation strategies are most strongly linked to specific innovation outcomes and competitive performance. The results reveal that employee enabling implementation strategies have a positive direct effect on employee performance and indirect effects on customer sentiment outcomes and the operational performance of the innovation. Administratively driven implementation strategies had a positive direct effect on customer comparative performance, and an indirect effect on a firm’s comparative operational performance as hypothesized. Finally, owners were more likely to be idea generators and principal early supporters of successful innovations, highlighting the power of top-down approaches to championing change within the European context

Applying interprofessional education to the practice setting.

Interprofessional education is a key requirement identified in various professional and regulatory body education standards in the UK. However, recent high-profile investigatory reports into adverse incidents in NHS organisations have demonstrated failures of translating interprofessional education into practice. This paper explores how a university in the south of England uses service improvement projects to address this. Working with key senior clinicians, small groups of students from a variety of professional backgrounds collaborate to address an identified problem in practice to bring about better, safer practice to benefit patients. This style of learning enables students to acquire essential attributes in preparation for employment, such as critical thinking, teamworking, ethical practice and leadership

Geomorphological control on boulder transport and coastal erosion before, during and after an extreme extra-tropical cyclone

Extreme wave events in coastal zones are principal drivers of geomorphic change. Evidence of boulder entrainment and erosional impact during storms is increasing. However, there is currently poor time coupling between pre- and post-storm measurements of coastal boulder deposits. Importantly there are no data reporting shore platform erosion, boulder entrainment and/or boulder transport during storm events – rock coast dynamics during storm events are currently unexplored. Here, we use high-resolution (daily) field data to measure and characterise coastal boulder transport before, during and after the extreme Northeast Atlantic extra-tropical cyclone Johanna in March 2008. Forty-eight limestone fine-medium boulders (n = 46) and coarse cobbles (n = 2) were tracked daily over a 0.1 km2 intertidal area during this multi-day storm. Boulders were repeatedly entrained, transported and deposited, and in some cases broken down (n = 1) or quarried (n = 3), during the most intense days of the storm. Eighty-one percent (n = 39) of boulders were located at both the start and end of the storm. Of these, 92% were entrained where entrainment patterns were closely aligned to wave parameters. These data firmly demonstrate rock coasts are dynamic and vulnerable under storm conditions. No statistically significant relationship was found between boulder size (mass) and net transport distance. Graphical analyses suggest that boulder size limits the maximum longshore transport distance but that for the majority of boulders lying under this threshold, other factors influence transport distance. Paired analysis of 20 similar sized and shaped boulders in different morphogenic zones demonstrates that geomorphological control affects entrainment and transport distance – where net transport distances were up to 39 times less where geomorphological control was greatest. These results have important implications for understanding and for accurately measuring and modelling boulde
