True and apparent scaling : the proximity of the Markov-switching multifractal model to long-range dependence

In this paper, we consider daily financial data of a collection of different stock market indices, exchange rates, and interest rates, and we analyze their multi-scaling properties by estimating a simple specification of the Markov-switching multifractal (MSM) model. In order to see how well the estimated model captures the temporal dependence of the data, we estimate and compare the scaling exponents H(q) (for q=1,2) for both empirical data and simulated data of the MSM model. In most cases the multifractal model appears to generate ‘apparent’ long memory in agreement with the empirical scaling laws.

Teaching and learning in collaborative group design projects

The 200 years of apprentice/master tradition that underpins the atelier studio system is still at the core of much present-day architectural design education. Yet this tradition poses uncertainties for a large number of lecturers faced with changes in the funding of tertiary education. With reductions in one-to-one staff/student contact time, many educators are finding it increasingly difficult to maintain an atelier teaching model. If these deficiencies remain unchecked and design-based schools are unable to implement strategies to reduce the resource intensity of one-to-one studio teaching programmes, then, for many higher-education providers, current architectural education may be based on an untenable course structure. Rather than spreading their time thinly over a large number of individual projects, an increasing number of lecturers are setting group projects. This allows them to coordinate longer and more in-depth review sessions on a smaller number of assignment submissions. However, while the group model may reflect the realities of the design process in professional practice, the approach is not without shortcomings as a teaching and learning archetype for the assessment of individual student skill competencies. Hence, what is clear is the need for a readily adoptable andragogy for the teaching and assessment of group design projects. The following is a position paper that describes – with a focus on effective group structures and assemblage and fair assessment models – the background, methodology and early results of a Strategic Teaching and Learning Grant currently running at the School of Architecture and Building at Deakin University in Australia.

The impact of teaching models, group structures and assessment modes on cooperative learning in the student design studio

As a result of ever diminishing teaching resources, an increasing number of architectural educators are setting group design projects, rather then spreading their time thinly over a large number of individual projects. This allows them to co-ordinate longer and more in-depth review sessions on a smaller number of assignment submissions. However, while the group
model may offer an authentic learning model by reflecting design in practice, the approach is not without its obvious shortcomings as a teaching archetype for the assessment of the knowledge and skill competencies of individual students. Hence, what is clear is the need for a readily adoptable andragogy for the teaching and assessment of group design projects.
The following paper describes the background, methodology and findings of a Strategic Teaching and Learning Grant funded research project carried out in the year 2005 at the School of Architecture and Building at Deakin University. The project aimed to inform a change of classroom/studio practice governing the assemblage, teaching and assessment of student design teams. The development through these changes of cooperative and student centred learning principles focused on effective design collaboration and fair assessment should, it will be argued, lead to an enhanced group-learning experience in studio, which will subsequently and ultimately enhance professional practice.

How well does the gudjonsson suggestibility scale for children, version 2 predict the recall of false details among children with and without intellectual disabilities?

Purpose. This study explored the effectiveness of the Gudjonsson Suggestibility Scale for Children, version 2 in predicting the tendency of older school-aged children (with and without intellectual disabilities) to generate errors in an independent suggestibility paradigm.

Method. Sixty-nine children with an intellectual disability (aged 9-14 years) and 50 mainstream children matched for chronological age participated in a 30-minute magic show that was staged at their school. Three days later, the children participated in a separate biasing interview that provided seven true and seven false details about the magic show. The following day, the children participated in a second interview where they were required to recall the magic show in their own words and answer a series of cued-recall questions. Between 1 and 2 weeks later, the children were administered the Gudjonsson Suggestibility Scale-2 (GSS-2).

Results. While there was no significant association between performance on the GSS-2 and the independent suggestibility paradigm for the children with an intellectual disability, the chronological age-matched children's yield scores predicted their reporting of both false-new details and false-interviewer suggestions for the independent event.

Conclusion. When predicting children's recall of false details, the GSS-2 appears to be more useful with mainstream school-aged children compared with children who have an intellectual disability.

Comparing codes of ethics among the top companies in Australia, Canada and the USA

In the twentieth century, industrialized economies around the world enacted legislation to protect free and fair trade. These legislative initiatives were often precipitated by exposure to unethical business practices. With the fairly recent corporate business scandals around the world, ethics is once again at the forefront of concerns about commercial exchanges. This situation has become more complex with the globalization of commercial trade. Subsequently, there have been various attempts by international organizations to regulate the conduct of global corporations. One key technique to try to regulate the conduct of corporation is the use of codes of ethics. This study examines corporate codes of ethics and the measures in place to communicate the ethos of the codes to both internal and external stakeholders in three countries. A questionnaire that was non-sponsored and unsolicited was sent to the top companies operating in the private sector within Australia, Canada and the USA. Nine key areas of corporate ethics are examined and they are divided into two categories as follows:

Regulation
Consequences for a Breach
Ethical Perfonnance Appraisal
Conduct Ethical Audits

Staff Support
Support of Whistle blowers
Guide to Strategic Planning
Ethics Committee
Ethics Training Committee
Staff Training
Ethics Ombudsman.

Iraq and the Arab revolutions : protesting the failure to democratise governance

As the Arab Revolutions swept across the Middle East and North Africa in late 2010 and into 2011, Iraqis were confronted with the failures of their own democracy to deliver on the many promises made to them since 2003. This led to weeks of scattered protests across Iraq, culminating in the “Day of Rage” (February 25, 2011) in which thousands of protestors took to the streets in at least 17 separate demonstrations across the country following Friday prayers. On the surface, these protests shared much in common with others across the region: the use of Facebook and other social media to promote the protests, and the focus on corruption, unemployment and poor public infrastructure. Also similar was the reaction of key Iraqi political figures such as Maliki and Barzani who met Iraqi protests with a mixture of brutal suppression and modest political and economic concessions. However, as this paper will demonstrate, upon closer inspection the Iraqi protests are in fact very different to others across the MENA and are therefore among the most significant for the future of democracy in the region. The Iraqi people were not protesting against an autocratic regime or an entrenched monarchy that had held power for decades, but a relatively new – and supposedly ‘democratic’ - political elite who had been brought to power in the wake of the US invasion. Indeed, while protestors across the region called for more democracy in the form of a written constitution, free and fair elections, a robust media sphere and the rule of law, Iraqis were protesting against the failures of the Iraqi government to democratise such mechanisms of governance (all of which they more or less have). They felt routinely disenfranchised by a state that has manipulated the very institutions and discourses of democracy to retain, rather than diffuse, power.

Manipulating Islam and democracy in Iraq’s ‘Pluralised Authoritarianism’

With the realisation that the initial motives for the 2003 invasion of Iraq – Saddam’s alleged stockpile of Weapons of Mass Destruction (WMD) and his links to Al-Qaeda – were grievous intelligence errors the Bush administration, with varying degrees of success, were able to spin the war’s rasion d’etre and redefine the parameters of victory. A central tenet of this approach was to begin speaking about democracy as if it had always been one of the aims of the war itself. For the first few years, the effort to democratise Iraq appeared to gain some credible momentum: a complex array of political, religious and ethno-sectarian factions formed political parties and civil society movements; uncensored news was enthusiastically consumed across the nation; Iraqi citizens took to the streets to protest key government decisions; and millions of Iraqis voted in relatively free and fair national elections (Davis, 2004, 2007, Isakhan, 2008, 2011b). Central to each of these developments were various Iraqi religious establishments – but especially those of the Shia Arab population of Iraq – who saw no distinction between their Islamic faith and the notion of democracy. Not surprisingly, a body of literature has emerged which has been very optimistic about Iraq’s engagement with both ‘Islam’ and ‘democracy’ in the post-Baathist period, while acknowledging the challenges it faces in creating a stable, egalitarian and democratic society (Al-Musawi, 2006, Cole, 2006, Davis, 2005, Dawisha, 2009, Isakhan, 2011a, Stansfield, 2007).

However, there have been virtually no studies which have sought to question this optimism in the light of more recent events. Addressing this lacuna, this paper documents the last few years (2006- 2011) which have seen many elements within the Iraqi political elite – most notably the Maliki government and his State of Law Coalition (SLC) – demonstrate what has been referred to in literature on other Arab states alternatively as ‘liberalised autocracy’ (Brumberg, 2002), ‘semi-authoritarianism’ (Ottaway, 2003) or ‘pluralised authoritarianism’ (Posusney and Angrist, 2005). That is to say, that these states consolidate their incumbency while putting in place measures that can be considered more or less liberal. To do this, the regime actually utilises (and controls) nominally democratic mechanisms such as elections, media freedoms, political opposition and civil society as part of their strategy to retain power. Of particular interest here are the ways in which the Maliki government – and Shia Arab Iraqi political factions more broadly – have manipulated both ‘Islam’ and ‘democracy’ towards such ‘pluralised authoritarianism’.

Dynamic threshold determination by local and global edge evaluation

In this paper we consider two methods for automatically determining values for thresholding edge maps. In contrast to most other related work they are based on the figural rather than statistical properties of the edges. The first approach applies a local edge evaluation measure based on edge continuity and edge thinness to determine the threshold on edge magnitude. The second approach is more global and considers complete connected edge curves. The curves are mapped onto an edge curve length/average magnitude feature space, and a robust technique is developed to partition this feature space into true and false edge regions. A quantitative assessment of the results on synthetic data shows that the global method performs better than the local method. Furthermore, a qualitative assessment of its application to a variety of real images shows that it reliably produces good results.

Relationships between stress-related working conditions and performance : a comprehensive investigation

The study examined if and how prominent stress-related working conditions were longitudinally associated with multiple employee performance behaviours. The findings revealed the positive influence of workload demands and the positive curvilinear effects attributed to relationship-based resources (support from colleagues, fair interpersonal treatments and fair information sharing) on performance long-term.

On self-propagating methodological flaws in performance normalization for strength and power sports

Performance in strength and power sports is greatly affected by a variety of anthropometric factors. The goal of performance normalization is to factor out the effects of confounding factors and compute a canonical (normalized) performance measure from the observed absolute performance. Performance normalization is applied in the ranking of elite athletes, as well as in the early stages of youth talent selection. Consequently, it is crucial that the process is principled and fair. The corpus of previous work on this topic, which is significant, is uniform in the methodology adopted. Performance normalization is universally reduced to a regression task: the collected performance data are used to fit a regression function that is then used to scale future performances. The present article demonstrates that this approach is fundamentally flawed. It inherently creates a bias that unfairly penalizes athletes with certain allometric characteristics, and, by virtue of its adoption in the ranking and selection of elite athletes, propagates and strengthens this bias over time. The main flaws are shown to originate in the criteria for selecting the data used for regression, as well as in the manner in which the regression model is applied in normalization. This analysis brings into light the aforesaid methodological flaws and motivates further work on the development of principled methods, the foundations of which are also laid out in this work.
