Pictorial Guide to the Groupers (Teleostei: Serranidae) of the Western North Atlantic
This guide was developed to assist with the identification of western North Atlantic grouper species of the genera Alphestes, Cephalopholis, Dermatolepis, Epinephelus,
Gonioplectrus, Mycteroperca, and Paranthias. The primary purpose for assembling the guide is for use with projects that deploy underwater video camera systems. The most
vital source of information used to develop the guide was an archive of underwater video footage recorded during fishery projects. These video tapes contain 348 hours of
survey activity and are maintained at the National Marine Fisheries Service (NMFS), Pascagoula, Mississippi. This footage spans several years (1980-92) and was recorded
under a wide variety of conditions depicting diverse habitats from areas of the western North Atlantic Ocean, Caribbean Sea, and Gulf of Mexico. Published references were
used as sources of information for those species not recorded on video footage during NMFS projects. These references were also used to augment information collected from video footage to provide broader and more complete descriptions. The pictorial guide presents information for all 25 grouper species reported to occur in the western North Atlantic. Species accounts provide descriptive text and illustrations depicting documented phases for the various groupers. In addition, species separation sheets based on important identification features were constructed to further assist with species identification. A meristic table provides information for specimens captured in conjunction with videoassisted fishery surveys. A computerized version enables guide users to amend, revise,
update, or customize the guide as new observations and information become available. (PDF file contains 52 pages.
Field Guide to the Searobins (Prionotus and Bellator) in the Western North Atlantic
Species identifications of Prionotus and Bellator are often difficult under field conditions owing to the large number of species and their overlapping taxonomic characteristics. This key is intended to provide a simplified, accurate means to identify adult searobins greater than 10 cm standard length. All recognized species from the
western North Atlantic, the Gulf of Mexico, and Caribbean Sea are included. (PDF file contains 30 pages.
Taming the interoperability challenges of complex IoT systems
of communication protocols and data formats; hence ensuring diverse devices can interoperate with one another remains a significant challenge. Model-driven development and testing solutions have been proposed as methods to aid software developers achieve interoperability compliance in the face of this increasing complexity. However, current approaches often involve complicated and domain specific models (e.g. web services described by WSDL). In this paper, we explore a lightweight, middleware independent, model-driven development framework to help developers tame the challenges of composing IoT services that interoperate with one another. The framework is based upon two key contributions: i) patterns of interoperability behaviour, and ii) a software framework to monitor and reason about interoperability success or failure. We show using a case-study from the FI-WARE Future Internet Service domain that this interoperability framework can support non-expert developers address interoperability challenges. We also deployed tools built atop the framework and made them available in the XIFI large-scale FI-PPP test environment
Motivations, expectations and experiences of Australian rural and regional planners
Despite playing an extremely important role in shaping communities, the role and contribution of planners is not widely understood or acknowledged. At the same time, there is a shortage of planners in Australia, especially in non-urban areas. Thus, though an online survey of 185 rural and regional planners, this research explores their motivations, expectations and experiences. Most enjoyed and felt confident in their role, explaining that they valued the relaxed family orientated rural lifestyle and the varied nature of the planning work. Although they sometimes felt isolated, the non-urban location provided quicker progression to senior roles, the ability to engage directly with the community and to see the consequences of their decisions. Only half felt their education had prepared them well for their role, citing gaps in terms of computerised modelling, team leadership and conflict resolution skills. Their feedback centred on providing a more practical course, focussing more on regional planning, and encouraging urban and rural experience placements. As the first study to quantifiably explore rural and regional Australian planners perceptions of their role and challenges, the findings illustrate current experiences, key planning challenges, perceived educational gaps and future priorities

Scaffolding cognitive and metacognitive strategy instruction in regular class lessons
The quality of teachers’ knowledge about how people learn influences students’ learning outcomes. Similarly, the quality of students’ knowledge about how they learn influences their engagement in self-regulated learning and consequently, their learning achievement. There is a gap between research findings that support these two premises and teaching-learning practices in classrooms. In this paper we describe attempts to reduce this gap. In Study 1 we surveyed early adolescent students’ cognitive and metacognitive strategy use and demonstrated that students’ cognitive and metacognitive strategy knowledge has substantial room for improvement. In Studies 2 and 3 we collaborated with teachers to embed explicit cognitive and metacognitive strategy instruction, using learning protocols, into regular class lessons. Studies 2 and 3 showed that the learning protocols slipped readily into teachers’ typical lesson designs, scaffolded teachers’ delivery of strategy instruction, and scaffolded some students’ acquisition of strategy knowledge, although progress was sometimes slow. Recommendations are presented for supporting teachers and students to engage with cognitive and metacognitive strategy instruction
Store Image as a Mediator of Consumer Purchase Intention in Kenyan Supermarkets
The intensity of competition in the retail sector in Kenya is driving supermarket managers to position store image as a tool of competitive advantage. This study examined the mediating effect of store image on the relationship between psychographic and psychological factors and consumer purchase intention in anchor supermarkets in Kenya. Descriptive cross sectional survey was applied on a sample of 384 consumers. The composite construct of psychographic and psychological factors was regressed on consumer purchase intention, resulting in a positive significant effect. It was established that store image partly mediates the relationship between psychographic plus psychological factors and consumer purchase intention. The study recommends building of positive reputation of the supermarket to attract and enhance the consumer’s intention to purchase.
