Granted, the plural idiom is sometimes reducible to the singular, e.g. ‘2 and 3 are prime is equivalent to ‘2 is prime and 3 is prime’. ‘Are prime’, however, belongs to the special class of predicates known as distributives. No such reductions are possible for the general case of collective (nondistributive) predicates, and they are to be found everywhere, from the everyday (‘Whitehead and Russell wrote Principia Mathematica’) to the heart of logic itself (‘The axioms are consistent’, ‘Those premises imply this conclusion’). It is no good dismissing grammatical number as a logically irrelevant complication like person or gender, since plural expressions are crucially involved in valid patterns of argument. To take an elementary example, ‘The Brontë sisters supported one another; the Brontë sisters were Anne, Charlotte and Emily; so Anne, Charlotte and Emily supported one another’. There can be no warrant for ignoring such patterns wh...

A Grounded-Theory Study of Meta-Attention in Golfers

Eight male golfers (7 competitive-elite and 1 successful-elite) were interviewed about their experiences of attentional processes in competitive golf. A Straussian grounded-theory approach was used throughout the research process, and interview transcripts were analyzed using open, axial, and selective coding. Results indicated that meta-attention is resource based, with metacognitive reflections of logistic and shot resources that facilitate attentional control. Attentional control required successful target selection, consistent preshot routines, and consistent postshot routines. Failures in wider or immediate resources or failure to initiate control routines can lead to internal distraction. The emergent theory provides an understanding of the function of meta-attention in golf performance that can be used by golfers, coaches, or psychologists to improve attentional strategies.

Addition of a Cyclophosphine to Nitriles: An Inorganic Click Reaction Featuring Protio, Organo, and Main-Group Catalysis

The reaction produces electron-rich heterocycles (four lone pairs) and features homoatomic -bond heterolysis, thereby combining the key features of the 1,3-dipolar cycloaddition chemistry of azides and cyclopropanes. We also report the first catalytic addition of P-P bonds to the CN triple bond. The coordination chemistry of the new heterocycles is explored. S. S. C. and V. T. A. acknowledge the Natural Sciences and Engineering Research Council of Canada for postdoctoral fellowships.

We chart its development, in which ‘On Denoting’ plays a part but not the part one might expect, before explaining why it eventually fails. We go on to consider many-valued functions, since they too bring in plural terms—terms such as ‘�4 ’ or the descriptive ‘the inhabitants of London ’ which, like plain plural descriptions, stand for more than one thing. Logicians need to take plural reference seriously if only because mathematicians take many-valued functions seriously. We assess the objection (by Russell, Frege and others) that many-valued functions are illegitimate because the corresponding terms are ambiguous. We also assess the various methods proposed for getting rid of them. Finding the objection ill-founded and the methods ineffective, we introduce a logical framework that admits plural reference, and use it to answer some earlier questions and to raise some more.

Uplink QoS-aware admission control in WCDMA networks with class-based power sharing

First International Conference on Quality of Service in Heterogeneous Wired/Wireless Networks

Efficient Call Admission Control (CAC) techniques are of paramount important in UMTS networks to ... more Efficient Call Admission Control (CAC) techniques are of paramount important in UMTS networks to satisfy the Quality of Service (QoS) requirements of different traffic classes and to utilize the system resources in an efficient manner. In this paper, we propose a novel uplink CAC framework to enhance existing UMTS networks on three related accounts. First, we introduce a measurement-based component to calculate the current load of the system; second, this measurement-based component is integrated with a power prediction module to estimate the load increment that the new call will bring into the system; and third, the proposed framework feeds the results obtained to a call admission control algorithm with a QoS-enforcing mechanism that gives each class of traffic different treatment based on the QoS requirement of the connections. To the best of our knowledge, ours is a first attempt towards combining the above components into one uplink CAC framework that aims to enhance system performance and to achieve per-class QoS objectives. Simulation results show that the framework is able to reduce dropping ratio for active users to zero level. Thus, it satisfies mobile users' needs resulting in a stable performance levels during heavy load periods. Furthermore, the framework provides a low blocking ratio for new calls, which translates into high resource utilization. This is a highly desirable property from the service provider point of view. 1 Hereafter, the term "RAB" will be used instead of a "call" to signify a radio connection. It more accurately captures the nature of 3G communications because a UMTS link can involve not only traditional voice calls but also multimedia transmissions and Web browsing sessions.
