Synthesis and reactivity of copper(I) phosphine-alkene complexes: X-ray crystal structure of CuCl(Ph2PCPh=CH2)(2)
No full textCopper(I) chloride complexes containing bifunctional phosphine/alkene ligands of the form CuCl(Ph2PCH=CH2)(n) (n = 1, 3) and CuCl( Ph2PCPh=CH2)(2) have been synthesized, with the latter being characterized by single crystal X-ray diffraction. Complexes decompose rapidly on reaction with hydroborating agents NaBH4 and Na[B(OMe)(3)H], although the thermally unstable Cu(BH4) (Ph2PCPh=CH2)(2) may be observed by NMR spectroscopy. The complexes show considerable resistance to thermally initiated alkene polymerization, the only significant reactivity for diphenylvinylphosphine complexes being trace ligand dissociation and subsequent aerobic oxidation to Ph2P(O)CH=CH2. Similar dissociation/oxidation is not observed for CuCl(Ph2PCPh=CH2)(2). Lewis acid initiated polymerization, using Et2O . BF3, results in the facile formation of copper(I) coordinated polymeric phosphine ligands for diphenylvinylphosphine complexes, but again no reactivity is induced in the more sterically hindered alpha-styrenyl analogue
Co-design for conceptual spaces: an agile design methodology for m-learning
No full textM-learning tools function in a number of different spaces, including physical contexts (visiting, at home, at work, etc.), and application areas (location-based information, communication, in-situ recording, etc). We have been exploring m-learning tools that operate in a conceptual space, in our case mobile tools to assist nursing students on placement. These tools are required to connect the user’s placement experience with the competency models required by the nursing professional bodies and National Health Service. Designing for conceptual spaces requires developers to work closely with domain specialists in order to model the space correctly, and to create functionally valuable tools. In this paper we present an agile co-design approach to developing mobile tools, which focuses on the requirements and analysis stage. This is largely ignored in current methodologies although it is critical for mobile systems working in conceptual spaces. We demonstrate the use of this methodology through the case study of our nursing placement project
Overcoming Geographical Obstacles: The Use Of Skype In A Graduate-Level Social Media And Marketing Course
No full textThis paper presents the results of a three-year research and teaching effort that focused on measuring the perceived effectiveness of Skype as a delivery platform for presentations made to students enrolled in a Professional MBA program by nationally acclaimed authors working in the area of social media. The research also investigated the authors ’ acceptance of Skype as a platform for delivering remote presentations to college audiences. The results indicated that both students and authors strongly supported the use of Skype as a presentation platform. The author presentations greatly enhanced the learning environment and contributed to achieving several specific course objectives
A Mobile Toolkit for Placement Learning
No full textStudents whose professional qualifications are gained through work placement-based learning are assessed as to their competency to carryout tasks. These students are usually supported by mentors, qualified practitioners who regularly meet with them and give feedback on their progress. This support can be highly variable, affecting the quality of the students’ learning experience. Through a process of co-design the mPLAT project has created a mobile toolkit to connect students’ placement experiences with the professional competency model that they are assessed against. The toolkit does this by matching their learning requirements to a placement and producing an Action Plan that acts as a focus for their reflection and for their meetings with their mentors
PRODUCT QUALITY AND VALUE FOR PROCESSED FOODS
No full textThis study investigates quality and value comparisons between national and private label brands of processed food products. Regression analyses indicate a weak relationship between price and quality for such products. Private label and national brands offer similar product quality while private labels offer better values for consumers
Social media: The new hybrid element of the promotion mix
No full textThe emergence of Internet-based social media has made it possible for one person to communicate with hundreds or even thousands of other people about products and the companies that provide them. Thus, the impact of consumer-to-consumer communications has been greatly magnified in the marketplace. This article argues that social media is a hybrid element of the promotion mix because in a traditional sense it enables companies to talk to their customers, while in a nontraditional sense it enables customers to talk directly to one another. The content, timing, and frequency of the social media-based conversations occurring between consumers are outside managers' direct control. This stands in contrast to the traditional integrated marketing communications paradigm whereby a high degree of control is present. Therefore, managers must learn to shape consumer discussions in a manner that is consistent with the organization's mission and performance goals. Methods by which this can be accomplished are delineated herein. They include providing consumers with networking platforms, and using blogs, social media tools, and promotional tools to engage customers.Integrated marketing communications Social media Consumer-generated media Promotion mix
