Evaluating Strategic and Dynamic Property Asset Allocation Approaches for Australian Superannuation Funds

Abstract For Australians, the $325 billion not-for-profit industry superannuation funds are a popular retirement saving option. To achieve their investment objectives, industry funds commonly apply the strategic asset allocation approach across seven diversified benchmarked asset classes. Fund managers regularly make adjustments to the strategic policy to reflect changes in investment markets. However, more recently, the volatile behaviour of the global financial markets has made it difficult for institutions to follow long-term strategies and polices. Consequently Australian fund managers are increasingly changing their asset allocation strategies to shorter term timeframe. In particular, adopting the dynamic asset allocation approach, which works on a medium term (3+ years) timeframe, is now viewed as a more effective strategy by fund managers. Covering a 17 year period, this research compares the performance of the industry fund strategic investment approach against two dynamic asset allocation models. In addition, the research investigates the role of property in these asset allocation strategies. The results show that the dynamic investment models provide a better risk-adjusted return profile compared to the industry fund strategic investment approach with scope to increase the property allocation level from current 10% to the 15-28% range.
Assessment practices of Canadian occupational therapists working with adults with mental disorders

Background. Little is known about assessment practices of occupational therapists working with adults with mental disorders. Purpose. This study investigates the assessment practices of occupational therapists working with clients experiencing symptoms of schizophrenia or major depressive disorder. Method. We conducted a national survey of assessment practices using case vignettes of hypothetical clients. Findings. From 343 vignettes completed by 286 respondents, 68.4% included the use of one or more standardized measures during treatment. Measures were rarely repeated. Results showed that the Canadian Occupational Performance Measure was the most frequently used, suggesting a focus on assessing global functioning, while the Assessment of Motor and Process Skills was listed as the most desired assessment tool. Implementing nonstandardized assessments was common. Implications. Despite wide variations in occupational therapists’ assessment practices, the use of standardized assessments is prevalent. The low rate of repeated measures (0% to 25.9%) suggests a need to better monitor changes and treatment outcomes.
The dynamic effects of shocks to labour markets: evidence from OECD countries

This paper uses a set of plausible long-run identifying restrictions on a three-variable system, including output growth, real wage growth, and the unemployment rate, to isolate three independent structural shocks which drive fluctuations in those variables in a sample of 16 OECD countries during 1950-96. These shocks are interpreted as aggregate demand, productivity, and labour supply disturbances. As a by-product of the previous analysis, the cyclical behaviour of real wages in response to a demand shock is re-examined and two indices of real wage rigidity are derived.

Prion interference with multiple prion isolates

Co-inoculation of prion strains into the same host can result in interference, where replication of one strain hinders the ability of another strain to cause disease. The drowsy (DY) strain of hamster-adapted transmissible mink encephalopathy (TME) extends the incubation period or completely blocks the hyper (HY) strain of TME following intracerebral, intraperitoneal or sciatic nerve routes of inoculation. However, it is not known if the interfering effect of the DY TME agent is exclusive to the HY TME agent by these experimental routes of infection. To address this issue, we show that the DY TME agent can block hamster-adapted chronic wasting disease (HaCWD) and the 263K scrapie agent from causing disease following sciatic nerve inoculation. Additionally, per os inoculation of DY TME agent slightly extends the incubation period of per os superinfected HY TME agent. These studies suggest that prion strain interference can occur by a natural route of infection and may be a more generalized phenomenon of prion strains.
Dynamic Equilibrium and the Real Exchange Rate in a Spatially Separated World

Two homogeneous stocks of physical capital are located in two different countries, separated by an "ocean. " They are consumed by local residents, invested in a random production process yielding real returns, or transferred abroad. Under proportional transfer costs, trade, consumption, and capital imbalances are shown to be persistent. The heteroskedastic process for the relative price of capital in the two countries has a nonlinear, mean-reverting drift. Nevertheless, the conditional probability of the price moving from the parity value of unity is greater than the probability of it moving toward parity. The real interest-rate differential incorporates a simple risk premium.

Dimerization of the hepatitis C virus nonstructural protein 4B depends on the integrity of an aminoterminal basic leucine zipper

The hepatitis C virus (HCV) nonstructural (NS) protein 4B is known for protein–protein interactions with virus and host cell factors. Only little is known about the corresponding protein binding sites and underlying molecular mechanisms. Recently, we have predicted a putative basic leucine zipper (bZIP) motif within the aminoterminal part of NS4B. The aim of this study was to investigate the importance of this NS4B bZIP motif for specific protein–protein interactions. We applied in silico approaches for 3D‐structure modeling of NS4B‐homodimerization via the bZIP motif and identified crucial amino acid positions by multiple sequence analysis. The selected sites were used for site‐directed mutagenesis within the NS4B bZIP motif and subsequent co‐immunoprecipitation of wild‐type and mutant NS4B molecules. Respective interaction energies were calculated for wild‐type and mutant structural models. NS4B‐homodimerization with a gradual alleviation of dimer interaction from wild‐type towards the mutant‐dimers was observed. The putative bZIP motif was confirmed by a co‐immunoprecipitation assay and western blot analysis. NS4B‐NS4B interaction depends on the integrity of the bZIP hydrophobic core and can be abolished due to changes of crucial residues within NS4B. In conclusion, our data indicate NS4B‐homodimerization and that this interaction is facilitated by the aminoterminal part containing a bZIP motif.
On data: a case study of the evolution of income inequality across time and across countries

This paper takes income distribution as a case study of the role of data in economics. After describing the transformation which has taken place with regard to the availability of data on income inequality, it discusses how the comparability of these estimates is brought into question by differences in methodology that cannot be eliminated by simple adjustments. Recent analyses of the relationships between income inequality and growth or globalisation are shown to be based on time series plagued by discontinuities which can seriously affect regression results. The paper concludes by calling for greater attention to data quality in applied economics.
Diode-Laser Wavelength-Modulation Absorption Spectroscopy for Quantitative in situ Measurements of Temperature and OH Radical Concentration in Combustion Gases.

The in situ quantitative profiles of temperature and OH radical concentration in a postflame region of methane-air premixed counterflow flames were measured by wavelength modulation spectroscopy with a 1.5-mum external cavity diode laser. The second harmonic (2f) signal was generated from absorption by overtone vibrational-rotational transitions of OH: the ? (3/2) (v? , v? ) = (2, 0) P11.5e (nu(0) = 6421.35 cm(-1)) or the ? (3/2) (v? , v? ) = (3, 1) P5.5f (nu(0) = 6434.61 cm(-1)) transitions. The absorption occurred in the postflame region between methane-air premixed twin flames stabilized in a two-dimensional laminar counterflow burner (Tsuji burner) with a 60-mm line-of-sight path length. The temperature and OH concentration profiles at an equivalence ratio of phi = 0.85 were determined by least-squares fitting of theoretical 2f line shapes to the experimental counterparts and by calculation of the ratio of the line intensities of the two different OH transitions (two-line thermometry). The measured temperature and OH concentration profiles were cross checked by Rayleigh scattering thermometry, thermocouple measurements, and two-dimensional numerical prediction of premixed combustion by use of a detailed chemical kinetic mechanism. The measurements and the prediction showed reasonable agreement.
On the Goals of Successful Family Companies

Providing clear goals for a company and communicating them are among the most powerful means for guiding the behavior of the people in an organization. In this article, we explore the range of objectives or goals of family-owned and -managed companies and identify those most commonly regarded as important by owner-managers. Further, we describe six major empirical dimensions of goals that we derived by factor-analytic procedures. Finally, we suggest how researchers, managers, and consultants can use our work to help owner-managers clarify and communicate their goals.
Complicated Appendicitis–Is the Laparoscopic Approach Appropriate? A Comparative Study with the Open Approach: Outcome in a Community Hospital Setting

Good outcome has been reported with the laparoscopic approach in uncomplicated appendicitis, but a higher incidence of postoperative intraabdominal abscesses has been reported after laparoscopic appendectomy in complicated appendicitis. This retrospective comparative study compares outcome after laparoscopic (LA) and open appendectomy (OA) in complicated appendicitis. All patients who had LA or OA for complicated appendicitis between January 2003 and February 2006 were included in the study. Data collection included demographics, operative time, estimated blood loss, length of stay (LOS), complications, readmission, and reoperative rates. The primary end points for analysis were postoperative intraabdominal abscess and complication rates and secondary end points were LOS and operative time. All data were analyzed on an intent-to-treat basis. Of 104 patients, 43 patients underwent LA and 61 had OA. The mean age (24.8 ± 16.5 versus 31.3 ± 18.9, P = 0.08) in the LA group was lower than the OA group because there was a significantly higher proportion of pediatric patients (34.8% versus 14.8%, P = 0.02) who had LA. There was no significant difference in gender (female/male, 14/29 versus 27/34, P = 0.3) or American Society of Anesthesiologists class distribution (American Society of Anesthesiologists 1/2/3/4/, 35/7/1/0 versus 45/12/3/1, P = 0.68) between the two groups. The operative time (100.5 ± 36.2 versus 81.5 ± 29.5 minutes, P = 0.03) was significantly longer and the estimated blood loss (21 mL versus 33 mL, P = 0.01) was lower in LA when compared with OA, but there was no significant difference in the number of patients with preoperative peritonitis versus abscesses (7/36 versus 13/48, P = 0.6) in both groups. There was no difference in the median LOS (6 [interquartile range 5–9] versus 6 [interquartile range 4–8], P = 0.7) in the two groups. The conversion rate in LA was 18.6% (n = 8). There was also no significant difference in the complication (17/43 [39.5%] versus 21/61 [34.4%], P = 0.54), reoperative (3/43 [7%] versus 0/61 [0%], P = 0.07), and 30-day readmission (5/41 [11.6%] versus 3/61 [4.9%], P = 0.23) rates between the two groups. The rate of postoperative intraabdominal abscesses was significantly higher in the LA group when compared with the OA group (6/43 [14%] versus 0/61 [0%], P = 0.04) and the wound infection (1/43 [2.3%] versus 5/61 [8.2%], P = 0.4) and pulmonary complication (0/43 [0%] versus 3/61 [4.9%], P = 0.26) rate was higher in the OA group. There was no mortality in the LA group, but there was one mortality in the OA group resulting from postoperative myocardial infarction. Laparoscopic appendectomy can be performed in patients with complicated appendicitis with a comparative operative time, LOS, and complication rates but results in a significantly higher intraabdominal abscess rate and lower wound infection rate when compared with OA.
Working With Adult English Language Learners With Limited Literacy: Research, Practice, and Professional Development

Center for Applied Linguistics 4646 40th Street NW Washington, DC 20016-1859 Background on Adult Learners Adult education programs serve both native English speakers and learners whose first, or native, language is not English. Native English speakers attend adult basic education (ABE) classes to learn basic skills needed to improve their literacy levels; they attend adult secondary education (ASE) classes to earn high school equivalency certificates. Both ABE and ASE instruction help learners achieve other goals related to job, family, or further education. English language learners attend English as a second language (ESL), ABE, or workforce preparation classes to improve their oral and literacy skills in English and to achieve goals similar to those of native English speakers.
Bootstrapping Financial Time Series

It is well known that time series of returns are characterized by volatility clustering and excess kurtosis. Therefore, when modelling the dynamic behavior of returns, inference and prediction methods, based on independent and/or Gaussian observations may be inadequate. As bootstrap methods are not, in general, based on any particular assumption on the distribution of the data, they are well suited for the analysis of returns. This paper reviews the application of bootstrap procedures for inference and prediction of financial time series. In relation to inference, bootstrap techniques have been applied to obtain the sample distribution of statistics for testing, for example, autoregressive dynamics in the conditional mean and variance, unit roots in the mean, fractional integration in volatility and the predictive ability of technical trading rules. On the other hand, bootstrap procedures have been used to estimate the distribution of returns which is of interest, for example, for Value at Risk (VaR) models or for prediction purposes. Although the application of bootstrap techniques to the empirical analysis of financial time series is very broad, there are few analytical results on the statistical properties of these techniques when applied to heteroscedastic time series. Furthermore, there are quite a few papers where the bootstrap procedures used are not adequate.
Neurological, functional, and biomechanical characteristics after high-velocity behind armor blunt trauma of the spine.

BACKGROUND Behind armor blunt trauma (BABT) describes a nonpenetrating injury to the organs of an individual wearing body armor. The aim of this study was to investigate the neurologic and functional changes that occur in the central nervous system after high-velocity BABT of the spine as well as its biomechanical characteristics. METHODS This study evaluated 28 healthy adult white pigs. Animals were randomly divided into three experimental groups: (1) 15 animals (9 in the exposed group and 6 in the control group) were tested for neurologic changes; (2) 10 animals (5 in the exposed group and 5 in the control group) were used for studies of cognitive function; (3) and 3 animals were used for examination of biomechanics. In the group tested for neurologic changes, 9 anesthetized pigs wearing body armor (including a ceramic plate and polyethylene body armor) on the back were shot on the eighth thoracic vertebrae (T8) with a 5.56-mm rifle bullet (velocity appropriately 910 m/s). As a control, six pigs were shot with blank ammunition. Ultrastructural changes of the spinal cord and brain tissue were observed with light and electron microscopy. Expression levels of myelin basic protein, neuron-specific enolase (NSE), and glial cytoplasmic protein (S-100B) were investigated in the serum and cerebrospinal fluid using enzyme-linked immunosorbent assays. Electroencephalograms (EEGs) were monitored before and 10 minutes after the shot. Pressures in the spine, common carotid artery, and brain were detected. Acceleration of the 10th vertebrae (T10) was tested. Finally, cognitive outcomes between exposed and control groups were compared. RESULTS Neuronal degeneration and nerve fiber demyelination were seen in the spinal cord. The concentrations of neuron-specific enolase, myelin basic protein, and S-100B were significantly increased in the serum and cerebrospinal fluid 3 hours after trauma (p < 0.05). The electroencephalogram was suppressed within 3 to 6 minutes after trauma. The pressure detected in the brain was higher than that detected in the common carotid artery (p < 0.01). The trauma resulted in paralysis of two hind limbs and in cognitive dysfunction. CONCLUSION The results from our animal model indicate that high-velocity BABT of the spine generates high pressure and acceleration in the spine, induces varying degrees of paralysis of hind limbs, and disturbs cerebral function. The neuronal degeneration caused by the pressure wave may be one of the important pathologic events involved in the development of trauma-related complications.
Using Random Utility Models to Estimate the Recreational Value of Estuarine Resources

In this paper we describe a model using a household production framework to link measures of nonpoint source pollution to fishing quality and a random utility model to describe how that quality influences sport fishing parties' decisions in North Carolina. The results provide clear support for using a model that evaluates the effects of pollution on the activities and decisions associated with the fishing activity once a trip is taken. Site selection decisions are then conditioned on the anticipated quality of fishing sites. The framework also has the advantage of linking the spatial, technical, and economic information required to evaluate the management plans required for estuaries under the National Estuarine Program.
Sustainable Development and Social Justice: Expanding the Rawlsian Framework of Global Justice

This article makes two arguments. First, that social justice constitutes an inherent part of the conception of sustainable development that the World Commission on Environment and Development outlined in Our Common Future (1987). The primary goal of the Commission was to reconcile physical sustainability, need satisfaction and equal opportunities, within and between generations. Sustainable development is what defines this reconciliation. Second, it is argued that this conception of sustainable development is broadly compatible with liberal theories of justice. Sustainable development, however, goes beyond liberal theories of justice in many respects. It is based on three assumptions, which are for the most part ignored in liberal theories: an accelerating ecological interdependence, historical inequality in past resource use, and the 'growth of limits'. These assumptions create a conflict between intra- and intergenerational justice, which is ignored in liberal theories, but which sustainable development tries to solve. It does so by imposing duties on developed countries that goes beyond liberal demands, and by abandoning the focus 'solely on protection' that dominates non-anthropocentric approaches to environmental sustainability.
Governing U.S. Metropolitan Areas

How are fragmented metropolitan areas characterized by multiple actors and multiple relationships governed? This has been a question of enduring interest in the study of local politics and policy. Recent works have made progress in understanding the emergence of self-organizing networks for individual service relationships. However, in the context of multiple service relationships, patterns of service networks that evolve as a consequence of local governments’ actions to address transaction problems have been long overlooked. This article begins to fill this gap in the literature by analyzing pay-for-service contracts across multiple municipal services in one metropolitan county in Florida. The results obtained from matrix correlation and matrix regression based on a quadratic assignment procedure reveal that local jurisdictions develop cross-service reciprocity networks in a multiple services contract environment to resolve credibility of commitment problems they encounter in entering and maintaining interlocal service contracts.
Segmenting Travel Markets with the International Tourism Role (ITR) Scale

Although many attempts have been made to segment travel markets, few studies have used conceptually-based, standardized instrumentation. This study illustrates how the International Tourism Role (ITR) scale by Mo, Howard, and Havitz (1993), developed using the conceptual framework of Cohen's (1972) tourist role typology, can be used to segment international tourist markets. Cluster analysis of ITR factor scores indicated the 461 respon dents could be classified into four distinct clusters. The clusters were confirmed by selected sociodemographic and behavioral trip characteristic variables. The composition of the clusters partially supported Cohen's classification scheme, but also revealed nuances result ingfrom the ITR scale's multidimensional interpretation of novelty in international tourism. Although results cannot be generalized beyond the study population, this study shows the potential for segmenting international travel markets with the ITR scale.
The Impact of Financial Participation and Employee Involvement on Financial Performance

In recent years, considerable attention has been given to the impact of various forms of financial participation on financial performance. However, financial participation is only one of a number of different schemes attempting to elicit better performance and is itself heterogeneous. Moreover, financial participation schemes are typically introduced in conjunction with employee involvement schemes and their combined effect can be very different from their individual contributions. Indeed, concentrating on only one type of participation can seriously distort its relationship with financial performance. In this paper, a range of different employee participation schemes is examined, including two types of financial participation. The results indicate that financial participation has important interaction effects with particular types of employee involvement scheme and that the two main types of financial participation scheme have negative interactions. Furthermore, some employee involvement schemes are found to have a lower or even negative relationship with financial performance when introduced in isolation.
