Adoption and feminism: Towards framing a feminist response to contemporary developments in adoption

In 2004 the sociologist Rosemary Pringle remarked that the 'climate of apology' surrounding adoption in Australia, linked with understandable shame regarding past adoption practices and the 'stolen generation' of Aboriginal children, meant that it had become 'almost impossible' to endorse adoption as a policy option (Pringle 2004, 225). In 2004, this was an apt call for all the reasons outlined astutely by Pringle

Assessment of Seasonal Variations in Forage Quality in Saanane Island National Park, Mwanza, Tanzania

Seasonal variations in proteins, vitamin A, vitamin C, carbohydrates and minerals (Ca, Fe, Na, K and P) for seven most grazed and four most browsed plant species were assessed using laboratory analysis to determine what nutrient resources were available to grazers and browsers inhabiting the Saanane Island. The results indicated great seasonal variations in proteins, vitamin A, vitamin C and carbohydrates which were statistically significant with P < 0.01, F 3.444 at DF 5. Similarly, the minerals (Ca, Fe, Na, K and P) showed greater seasonal variations with K and P being higher during wet season, while Na and Fe were higher in dry season. The levels of proteins, vitamins, fibres and minerals were well above daily dietary requirements for grazers and browsers. These results suggested that both grazers and browsers were benefiting from seasonal differences in terms of available resources at disposal as animal health is regulated by levels of proteins and vitamins available in grazing and browsing materials.  Keywords: Forage Quality, Minerals, Protein Saanane, Seasonality, Vitamin

'Why can't I have my baby tomorrow?': A legislative periodisation of intercountry adoption in Victoria and Australia from the early 1970s to the present

Intercountry adoption involves relatively small and currently declining numbers. But it is a platform for Australia's engagement with the wider world, and a highly contested field. Efforts to rationalise and regulate the field have to reconcile many competing interests, inside and outside Australia. This periodic overview focuses on government responses to the evolving practice of intercountry adoption from the end of the Vietnam War, charting the emergence of the current regulatory regime. It uses Victoria as a case study, to show the intricacies of a split state/federal jurisdiction, the challenge of transnational regulation in a globalised world, the flow-on effect of enabling legislation, and the impact of public scandals

Unilateral vs. bilateral hamstring strength assessments: comparing reliability and inter-limb asymmetries in female soccer players

The aims in the present study were to assess reliability for two unilateral and two bilateral field-based hamstring assessments and compare magnitude, direction and agreement of inter-limb asymmetry between tests and sessions. Twenty-nine female soccer players (age: 21.1±4.5 years; height: 169.7±5.8 cm; body mass: 66.2±6.4 kg) performed three repetitions per leg of unilateral isometric 30° (ISO 30°) and 90° (ISO 90°) knee flexion (KF) tasks, and three repetitions total for a bilateral 90° isometric (kneeling ISO) KF and Nordic hamstring exercise (NHE). Absolute reliability of most methods within- and between-session were acceptable (<10%). Relative reliability within-session demonstrated fair to excellent reliability (ICC≥0.784; lower bound 95%CI ≥0.623). Greater variability in between-session relative reliability was observed during the unilateral tests, demonstrating poor to good (ICC=0.698–0.798; lower bound 95%CI = 0.274–0.638). Bilateral assessments demonstrated similar ranges of poor to excellent (ICC=0.679–0.963; lower bound 95%CI = 0.231–0.790). Agreement between-session for inter-limb asymmetry identification was slight and fair in the unilateral tests, with moderate to substantial agreement demonstrated in the bilateral. Being the most reliable within- and between-sessions, demonstrating substantial agreement in asymmetry between-sessions, the NHE would be most appropriate to identify inter-limb asymmetry and assess chronic changes in hamstring strength

The application of change of direction deficit to evaluate cutting ability

The purpose of this study was to examine the application of the change of direction deficit (CODD) to a 90° cut test in order to examine whether CODD provides a unique evaluation of an individual’s cutting ability. Thirty-six male collegiate team–sport (23 Rugby/ 13 Soccer) athletes (age: 20 ± 1.4 years; height: 1.80 ± 0.08 m; mass: 83 ± 13.2 kg) participated in the study. Each athlete performed 3 trials of a 20 m sprint (with 5 m and 10 m splits) and 2 change of direction [COD] tests (90° cut and 505 tests) cutting/ turning from both limbs. Completion times for all sprint and COD tests were measured using timing cells. For both COD tests, CODD was determined (COD completion time – 10 m sprint time). Pearson’s correlation was used to explore relationships between sprint times and CODD and completion times. Significant (P 0.05) trivial to small correlations (r ≤ 0.199) were found between sprint variables and 90° cut CODD. Significant (P < 0.001) large to very large correlations (r ≥ 0.531) were revealed between left and right 90° cut and 90° cut CODD. The results suggest the CODD could be applied to isolate and assess cutting ability in COD speed tests that involve a single cutting maneuver. Failure to inspect CODD could lead to incorrect evaluation of an athletes cutting or COD ability

Strong "quantum" chaos in the global ballooning mode spectrum of three-dimensional plasmas

The spectrum of ideal magnetohydrodynamic (MHD) pressure-driven (ballooning) modes in strongly nonaxisymmetric toroidal systems is difficult to analyze numerically owing to the singular nature of ideal MHD caused by lack of an inherent scale length. In this paper, ideal MHD is regularized by using a $k$-space cutoff, making the ray tracing for the WKB ballooning formalism a chaotic Hamiltonian billiard problem. The minimum width of the toroidal Fourier spectrum needed for resolving toroidally localized ballooning modes with a global eigenvalue code is estimated from the Weyl formula. This phase-space-volume estimation method is applied to two stellarator cases.Comment: 4 pages typeset, including 2 figures. Paper accepted for publication in Phys. Rev. Letter

Analytical Modeling of a Large Local Area Network - Part I: Internet Traffic Characterization

The goal of both IP network operators and the end users is to get the highest performance from the system for a given cost. This makes Performance a key criterion in the design, procurement, and use of computer and communication systems. In order to address problems associated with performance degradation of operational communicationssystems, over the last decade, traffic engineering techniques have emerged in an attempt to optimize communication systems’ performance and ensure more efficient use of their resources. One of these techniques is analytical modeling. Analytic performance models are an excellent tool for quickly evaluating the performance of operational or new systems. They are also well suited to comparing the performance of several alternative designs. However, analytical models can only be developed once detailed knowledge of characteristics of trafficcarried by a network is available. In Part I of this paper, traffic characterization of traffic carried by the largest Local Area Network (LAN) in Tanzania, University of Dar es Salaam Network (UDSMNET) is carried out. In Part II of this paper, an analytical model based on the Discrete Time Markov Modulated Poisson Process is proposed and validated for performance analysis of IP networks
