Defining Dad: Media Depiction Of The Modern Father In Print Advertising

From an advertising perspective fathers are a highly attractive consumer demographic. In order to market to this audience it is important to understand how fathers are framed. With an increase in the number of fathers identifying themselves as caregivers according to the 2012 census, effective marketers would be well-served if they understood what type of frame applies when fathers are employed vs. stay at home. This analysis used framing theory to determine how message givers use frames within their advertisements to explain which particular aspects of the father are given salience. This study is a content analysis of father frames in advertising over a variety of highly circulated men’s magazines from 2009-2014. This analysis divided the magazines into two-time periods and looked for examples of care-giving fathers, wage-earning fathers, and recreational fathers in advertisements. In addition, the analysis looked at the question of competence in these advertisements, observing if the fathers were depicted as competent or not. The research supported that the dominant father frame of the pre-2012 time period was the care-giving father and the dominant father frame of the post-2012 time period was the recreational father. Fathers were not mostly observed as competent. This study supported the idea that the post-2012 father frame in male-based highly circulated magazines is more likely to be a father who leads their children in leisurely activities

Board independence, sub-committee independence and firm performance: evidence from Australia

This study investigates whether the monitoring of company management by an independent board of directors serves to enhance firm performance in Australia. The paper explores in detail the impact of the level of independence of the main board and sub-committees including audit, remuneration and nomination on performance in a sample of 250 listed companies. From the perspective of a regulator, the study’s findings have implications and suggest that an independent main board produces superior results. The shareholding of independent directors is also found to negatively impact performance for this data, suggesting that their role as independent arbiter is restricted by shareholding. Interestingly, the returns to firm performance engendered by independence did not extend to the composition of sub-committees, where the presence of outside directors did not significantly influence performance

The bearing of studies of expertise and experience on ethnography

In a recent article published in this journal, Atkinson and Morris explore the kinds of expertise and competence needed by ethnographic researchers. In doing so, they refer to the work of Collins and Evans and, in particular, the idea of interactional expertise, which they dismiss as largely unhelpful to their project. In this response, we show that the Atkinson and Morriss miss-represent this work in important ways and that, if these mistakes are corrected, interactional expertise provides a useful way of addressing the methodological concerns they identify

DPOS: A metalanguage and programming environment for parallel processors

Journal ArticleThe complexity and diversity of parallel programming languages and computer architectures hinders programmers in developing programs and greatly limits program portability. All MIMD parallel programming systems, however, address common requirements for process creation, process management, and interprocess communication. This paper describes and illustrates a structured programming system (DPOS) and graphical programming environment for generating and debugging high-level MIND parallel programs. DPOS is a metalanguage for defining parallel program networks based on the common requirements of distributed parallel computing that is portable across languages, modular, and highly flexible. The system uses the concept of stratification to separate process network creation and the control of parallelism form computational work. Individual processes are defined within the process object layer as traditional single threaded programs without parallel language constructs. Process networks and communication are defined graphically within the system layer at a high level of abstraction as recursive graphs. Communication is facilitated in DPOS by extending message passing semantics in several ways to implement highly flexible message passing constructs. DPOS processes exchange messages through bi-directional channel objects using guarded, buffered, synchronous and asynchronous communication semantics. The DPOS environment also generates source code and provides a simulation system for graphical debugging and animation of the programs in graph form

Using utilization profiles in allocation and partitioning for multiprocessor systems

Journal ArticleThe problems of multiprocessor partitioning and program allocation are interdependent and critical to the performance of multiprocessor systems. Minimizing resource partitions for parallel programs on partitionable multiprocessors facilitates greater processor utilization and throughput. The processing resource requirements of parallel programs vary during program, execution and are allocation dependent. Optimal resource utilization requires that resource requirements be modeled as variable over time. This paper investigates the use of program profiles in allocating programs and partitioning multiprocessor systems. An allocation method is discussed. The goals of this method are to (1) minimize program execution time, (2) minimize t h e total number of processors used, (3) characterize variation in processor requirements over the lifetime of a program, (4) to accurately predict the impact on run time of the number of processors available at any point in time and (5) to minimize fluctuations in processor requirements to facilitate efficient sharing of processors between partitions on a partitionable multiprocessor. An application to program partitioning is discussed that improves partition run times compared to other methods

A communication-ordered task graph allocation algorithm

technical reportThe inherently asynchronous nature of the data flow computation model allows the exploitation of maximum parallelism in program execution. While this computational model holds great promise, several problems must be solved in order to achieve a high degree of program performance. The allocation and scheduling of programs on MIMD distributed memory parallel hardware, is necessary for the implementation of efficient parallel systems. Finding optimal solutions requires that maximum parallelism be achieved consistent with resource limits and minimizing communication costs, and has been proven to be in the class of NP-complete problems. This paper addresses the problem of static allocation of tasks to distributed memory MIMD systems where simultaneous computation and communication is a factor. This paper discusses similarities and differences between several recent heuristic allocation approaches and identifies common problems inherent in these approaches. This paper presents a new algorithm scheme and heuristics that resolves the identified problems and shows significant performance benefits

Critical Casimir Forces and Colloidal Phase Transitions in a Near-Critical Solvent : A Simple Model Reveals a Rich Phase Diagram

From experimental studies it is well-known that colloidal particles suspended in a near-critical binary solvent exhibit interesting aggregation phenomena, often associated with colloidal phase transitions, and assumed to be driven by long-ranged solvent mediated (SM) interactions (critical Casimir forces), set by the (diverging) correlation length of the solvent. We present the first simulation and theoretical study of an explicit model of a ternary mixture that mimics this situation. Both the effective SM pair interactions and the full ternary phase diagram are determined for Brownian discs suspended in an explicit two-dimensional supercritical binary liquid mixture. Gas-liquid and fluid-solid transitions are observed in a region that extends well-away from criticality of the solvent reservoir. We discuss to what extent an effective pair-potential description can account for the phase behavior we observe. Our study provides a fresh perspective on how critical fluctuations of the solvent might influence colloidal self-assembly.Comment: 4 pages, 4 figure
