Good governance - not just for the big boys governance in organizations in New Zealand

Good governance is recognized as a fundamental indicator of the success of a company. For a small- midsized company, this is particularly so, as such companies must be able to competitively demonstrate their flexibility in the face of market forces. This flexibility is the primary advantage they hold over larger firms (Dalton, Daily, Ellstrand and Johnson, 1998). Such companies, however, can find it difficult to attract good directors (Daum and Neff, 2003) and this makes developing improved strategies of governance a challenge. Taylor, Chait and Holland suggest top directors are not attracted to small/ medium companies because “the stakes remain low, the meetings process-driven, the outcomes ambiguous, and the deliberations insular” (Taylor, Chait and Holland, 2001). We suggest that the attraction of quality directors is a uniquely impacting situation for small and mid-size firms, as it is there where additional management resources should be needed most urgently. Directors on the boards of small-medium sized businesses are often lagging behind directors of large companies in that they are less likely to be independent external directors and are less likely to represent a diversity of attributes (Dalton, Daily, Ellstrand and Johnson, 1998). Arthur Levitt, former United States Securities and Exchange Commission Chair, describes the culture of medium sized business directorships as a “kind of a fraternity of CEOs who serve on one another's boards” (Stainburn, 2005). In addition, evidence suggests directors of small- medium businesses are often insufficiently trained for the role. Uncertain directors may, for example, be unwilling to ask crucial questions of managers before making major decisions. “Board members sometimes are made to feel that asking a thorny question or advancing an alternative opinion is disloyal to the administration” (Taylor, Chait and Holland, 2001). Small and medium businesses, however, are a growing contributor to the national economies of countries internationally. In New Zealand, small and medium-size firms recording large GDP values, ahead of many large businesses, which makes our investigation into good governance practices of SMEs relevant to suggest areas in which these firms can improve their governance policies and practices. We have reviewed more than 2,000 directors, executives and investors in New Zealand, making this one of the largest non-government surveys in governance. Supported by 16 large corporate organizations, such as KPMG, Business New Zealand, Simpson Grierson, Brook Asset Management, Porter Novelli, Sheffield and ‘Management’ Magazine, this work suggests that the current processes through which directors are selected and trained to serve on Boards of small and medium businesses needs to be altered. We are also concerned over the lack of director education and the close involvement of the Chief Executives as members of the Boards. There is a general concern over the lack of director independence and whether directors are effective in their roles. We are recommending an alternative process for SMEs to select directors, which will hopefully expand the available pool of directors in quantity and quality.

Predicting psychological and subjective well-being from personality: incremental prediction from 30 facets over the Big 5

This study investigated the relationship between the Big 5, measured at factor and facet levels, and dimensions of both psychological and subjective well-being. Three hundred and thirty-seven participants completed the 30 Facet International Personality Item Pool Scale, Satisfaction with Life Scale, Positive and Negative Affectivity Schedule, and Ryff’s Scales of Psychological Well-Being. Cross-correlation decomposition presented a parsimonious picture of how well-being is related to personality factors. Incremental facet prediction was examined using double-adjusted r2 confidence intervals and semi-partial correlations. Incremental prediction by facets over factors ranged from almost nothing to a third more variance explained, suggesting a more modest incremental prediction than presented in the literature previously. Examination of semi-partial correlations controlling for factors revealed a small number of important facet-well-being correlations. All data and R analysis scripts are made available in an online repository.

A general communication cost optimization framework for big data stream processing in geo-distributed data centers

With the explosion of big data, processing large numbers of continuous data streams, i.e., big data stream processing (BDSP), has become a crucial requirement for many scientific and industrial applications in recent years. By offering a pool of computation, communication and storage resources, public clouds, like Amazon's EC2, are undoubtedly the most efficient platforms to meet the ever-growing needs of BDSP. Public cloud service providers usually operate a number of geo-distributed datacenters across the globe. Different datacenter pairs are with different inter-datacenter network costs charged by Internet Service Providers (ISPs). While, inter-datacenter traffic in BDSP constitutes a large portion of a cloud provider's traffic demand over the Internet and incurs substantial communication cost, which may even become the dominant operational expenditure factor. As the datacenter resources are provided in a virtualized way, the virtual machines (VMs) for stream processing tasks can be freely deployed onto any datacenters, provided that the Service Level Agreement (SLA, e.g., quality-of-information) is obeyed. This raises the opportunity, but also a challenge, to explore the inter-datacenter network cost diversities to optimize both VM placement and load balancing towards network cost minimization with guaranteed SLA. In this paper, we first propose a general modeling framework that describes all representative inter-task relationship semantics in BDSP. Based on our novel framework, we then formulate the communication cost minimization problem for BDSP into a mixed-integer linear programming (MILP) problem and prove it to be NP-hard. We then propose a computation-efficient solution based on MILP. The high efficiency of our proposal is validated by extensive simulation based studies.

Big change questions : can we create a form of public education that delivers high standards for all students in the emerging knowledge society?

Within many Anglophone nation states there is significant debate about
the future of public education and its ongoing capacity to provide quality
education. The new knowledge economy not only challenges the position
of educators as the primary producers, disseminators and authorizers of
what is valued knowledge, but also requires them to prepare students for
new ways of working with that knowledge. In the service economies of
post-industrial Western nations, 'knowledge work' is critical to national
productivity and international competitiveness. At the same time, the
globalization logic suggests that the nation state is under threat, and therefore its role as provider of universal services such as education is also threatened.

What are we looking at, and how big is it?

Some of the most important outcomes of physical therapy treatment have to do with behaviour and quality of life. This article involves examining what it is we are measuring in physical therapy research and what those measurements mean. In looking at differences between groups (e.g. placebo-control) or strength of association between variables (e.g. correlation, regression) the practitioner/researcher must consider what are meaningful magnitudes of effects. Depending on the variable that one measures, a medium effect size (e.g. Cohen's d=0.50) may, in the real world, be insignificant, or in the case of elite athletic performance such an effect size might be gigantic. A major problem in the sports sciences is the confusion of p values and significance testing with the results of interest, the magnitudes of effects. Also, the prevalence of possible Type II errors in the sports sciences and medicine may be quite high in light of the small sample sizes and the paucity of power analyses for non-significant results. We make an appeal for determining a priori minimal meaningful differences (or associations) to use as the primary metrics in discussing results.

Who's afraid of the big bad fish? Rethinking what the law wishes to have

This article aims to re-evaluate the contribution of Stanley Fish to legal studies. In  "The Law  Wishes to Have a Formal existence", Fish accused the law of maintaining a formal,  positivistic self-image as principled; an activity rhat rises above processes of interpretation and of moral judgement. For this `antiformalist‘ Fish there is thus a false sense of self-sufficent closure to the law's discourse. More recently however: in discussing the practice of another profession (namely literary criticism) Fish demonstrates that the basis of aclivity per se is internal intelligibility - that is intelligibility  within a defined community. These apparent  inconsistencies are explored. Re-reading `The Law Wishes to Have a Formal Existence' one can discern errors in Fish's account of a key case and one can also find support for the  professionalism position that he subsequently articulates. It is therefore argued that  Fish's account of the general characteristics of professional practice, including legal, are of value. The implications of his account of professionalism in the law are, however, incompatible with the usual understanding of his more combative statements about the role of formal language and principle-based argument of the law.

Using the Big Mac index for comparing construction costs internationally

This paper explores the use of purchasing power parity (PPP) in the comparison of construction costs between different countries, and whether the development of construction-specific indices will improve reliability.

The approach adopted is to compare the construction cost of a typical five star international hotel per square metre in each of ten major cities using a range of PPP methods and to comment on their variability. In particular, this paper looks at whether an index based on the price of a McDonalds Big Mac3 hamburger is a viable alternative when compared against the mainstream methods. The recent publication of construction-specific indices as part of the Eurostat-OECD joint PPP program is also compared against generic indices and the discrepancy is calculated.

The paper concludes with reflections about which approach is preferable when attempting to assess global construction relativities and what further research is needed.

The power of rhythm and words : from little things big things grow

Primary literacy teacher educators need to re-conceptualise the ways in which they work together to model effective interdisciplinary practice. This paper reports on such practice in a team teaching unit for postgraduate students undertaking the Bachelor of Teaching (Primary/Secondary) at Deakin University, Melbourne. The interdisciplinary (Social Education, Language and Music) unit, a first in the Faculty of Education was conceptualised to challenge both lecturer and student (local and international) to 'rethink' their understandings of pedagogy, multi-literacies and teacher preparedness. For the purpose of this paper, the authors reflect on a particular team teaching experience whereby a text (song) was used to teach both the elements of music and literacy pedagogy. It opened up new possibilities for students to engage and participate with each discipline as well as how one area can inform and further deepen the understanding for learners of the other. For example, musical notation and score was used to explain and use the 4 resource model (Luke and Freebody, 1990). The authors contend that crossdisciplinary work cannot be reduced to simple cooperation among disciplines but that primary literacy teacher educators need to develop new conceptual frameworks for learning that will enhance their understandings of pedagogy and assist in preparing teachers in a challenging world.

Identification of an integral plasma membrane pool of protein kinase C in mammalian tissues and cells

Protein kinase C (PKC) is a family of serine/threonine protein kinases that are pivotal in cellular regulation. Since its discovery in 1977, PKCs have been known as cytosolic and peripheral membrane proteins. However, there are reports that PKC can insert into phospholipids vesicles in vitro. Given the intimate relationship between the plasma membrane and the activation of PKC, it is important to determine whether such “membrane-inserted” form of PKC exists in mammalian cells or tissues. Here, we report the identification of an integral plasma membrane pool for all the 10 PKC isozymes in vivo by their ability to partition into the detergent-rich phase in Triton X-114 phase partitioning, and by their resistance to extractions with 0.2 M sodium carbonate (pH 11.5), 2 M urea and 2 M sodium chloride. The endogenous integral membrane pool of PKC in mouse fibroblasts is found to be acutely regulated by phorbol ester or diacylglycerol, suggesting that this pool of PKC may participate in cellular processes known to be regulated by PKC. At least for PKCα, the C2–V3 region at the regulatory domain of the kinase is responsible for membrane integration. Further exploration of the function of this novel integral plasma membrane pool of PKC will not only shed new light on molecular mechanisms underlying its cellular functions but also provide new strategies for pharmaceutical modulation of this important group of kinases.

Purchase commitments : Big business bias or solution to the 'neglected diseases' dilemma?

Miniscule research resources are allocated to researching the diseases of developing countries such as malaria, tuberculosis (TB), dengue fever, river blindness, Chagas disease and leishmaniasis, and the strains of HIV prevalent in Africa. Plainly, the patent system and the commercial model of drug research fail to respond to the needs of the poor for the simple reason that the poor exercise little purchasing power. But pressures are mounting on governments and corporations to tackle the ‘neglected diseases’ calamity. An important argument in an intense global debate is that corporations would respond to the needs of developing countries if the diseases of the poor could be made profitable. This is the idea developed by Kremer and Glennerster in a crisply written book, Strong Medicine: Creating Incentives for Pharmaceutical Research on Neglected Diseases.
