Can a Paradigm Shift from Risk Management to Critical Reflection Improve Child-Inclusive Practice?

Child protection systems within Anglophone countries have been increasingly dominated by neoliberal managerial, risk-dominant paradigms over the past three decades. Assumed to deliver a cost-effective strategy to increase the safety of children, there are many ways this paradigmatic combination systematically undermines child welfare, participation, and well-being. This paper specifically focuses on the ways that risk assessment, neoliberal, and managerial discourses have infiltrated practice and operate to silence and exclude children’s voices. It draws on two case studies to showcase key findings of a comprehensive, state-wide research project called Empowering Children’s Voices, which was initiated by UnitingCare, a non-government organisation within Queensland, Australia, and conducted in partnership with researchers from Queensland University of Technology. It will be argued that a paradigm shift towards a critically reflective reinterpretation of risk can be far more effective at promoting child-inclusive practice and establishing children’s empowered voices as a protective factor against harm.
Effects of Riblets on the Loss Behavior of a Highly Loaded Compressor Cascade

An experimental investigation of the influence of riblet surface structures on the loss behavior of a highly loaded compressor cascade V103-180 featuring a large chord length for high spatial resolution of the flow phenomena was performed. The cascade experiments were carried out at the High Speed Cascade Wind Tunnel of the University of the Armed Forces Munich in order to simulate realistic Mach and Reynolds numbers. The riblets used for the first investigation are of symmetric v-groove type with heights of 0.0762, 0.1143 and 0.1524 mm, respectively [1]. With two total pressure probes simultaneously traversed over one pitch behind the center airfoil, the local total pressure difference between the structured and the smooth blade is determined. From these measurements, the total pressure loss coefficient can be evaluated. For a better understanding of the flow phenomena, the profile pressure distribution is measured for the smooth and the structured blade. Boundary layer calculations were performed in order to optimise the riblet size for the design conditions of the compressor cascade. Resulting from the measurements an optimised riblet configuration (size and shape) has been manufactured and transferred to the cascade. Further flow measurements have been performed in order to evaluate the total pressure loss coefficient. Additional insight into the flow phenomena of the boundary layer has been achieved by laser-two-focus measurements. The experimental results indicate that the riblets mainly influence the suction side boundary layer behaviour. The ideal dimensionless groove height is obtained h+ = 9 leading to a reduction of the loss coefficient of 6–8%. Values of h+ > 20 cause an increase of the loss coefficient due to the development of a turbulent boundary layer separation.Copyright © 2002 by ASME
State of the art of semiconducting glazed insulators for transmission lines in heavily contaminated area

Semiconducting glazed insulators were developed long time ago. They, however, have been used in quite limited areas because of long-term reliability of performance was uncertain. Recent investigation results on our semiconducting glazed insulators applied in the field for 14 years showed good long-term performance without any failures. It was achieved by proper design of the insulators and improved material of semiconducting glaze. Good performance was verified by field and laboratory test results. Contamination withstand voltage was around 2-3 times higher than that of ordinary glazed insulators. In addition, the semiconducting glazed insulators could reduce corona discharge under contaminated conditions very much. Therefore, they can be applied for actual transmission lines and can make it possible to built compact lines.
How malleable are cognitive abilities? A critical perspective on popular brief interventions.

A number of popular research areas suggest that cognitive performance can be manipulated via relatively brief interventions. These findings have generated a lot of traction, given their inherent appeal to individuals and society. However, recent evidence indicates that cognitive abilities might not be as malleable as preliminary findings implied and that other more stable factors play an important role. In this article, I provide a critical outlook on these trends of research, combining findings that have mainly remained segregated despite shared characteristics. Specifically, I suggest that the purported cognitive improvements elicited by many interventions are not reliable, and that their ecological validity remains limited. I conclude with a call for constructive skepticism when evaluating claims of generalized cognitive improvements following brief interventions.

Becoming generous and respecting honor: An experiment based on donation and trust-game with multiple trustees

This research explores the reoccurring conflict of speculations and explanations among social scientists regarding why people do charity or behave generously. Our participants were 256 subjects, 34% males and 65.2 % females. Based on a donation task we elicit the most honorable member in a group of four participants. This participant receives a substantial monetary reward and recognition as the most generous donor in the group. An unannounced subsequent phase confronts the honor participant with the task of a single contributor in a best-shot trust game. Without knowing what this honor participant has contributed, the three other participants independently compensate the contributor. We view the contribution level as measuring honor and compensations as measuring respect of honor. With the help of these choice data and additional information from the initial phase as well as from post experimental questionnaires, we assess whether respect of honor reacts monotonically to contributions and how aspects deciding who is honored influence contribution levels and respective compensations. Treatments vary in the (non) linearity of contribution costs. In both treatments we find that honor participants contribute generously to increase their group’s welfare, even at the cost of their own profit. Honor participants seem to care for their role and justify their entitlement to this position. Other participants reward respect to honor participants by compensating them.
OTA-C realisation of general high-order transfer functions

OTA-C technology has become a very important topic in continuous-time integrated circuits owing to its advantages over other realisation techniques. In the research of OTA-C filters, the synthesis of second-order filters has been widely investigated but the realisation of high-order transfer functions has not received similar attention. The authors propose a novel higher-order OTA-ground capacitor network and explicitly formulate realisation techniques for general transfer functions. >
Smartphone Addiction, Social Support, and Cybercrime Victimization: A Discrete Survival and Growth Mixture Model

ABSTRACT In recent decades, criminological theories have identified a set of vulnerabilities in potential victims that seek to explain their victimization. When it comes to explaining cybercrime victimization, however, the important role that addiction to the vulnerabilities associated with technological devices can play has tended to be overlooked. In this paper we empirically link smartphone addiction, social support, and cyberfraud victimization in a nationally representative sample of 716 smartphone users followed for three years. The results of discrete survival and growth mixture models suggest that the probability of cyberfraud victimization is lower among users with a decrease in smartphone addiction and an increase in social support over the three years. These results allow us to suggest new avenues in the study of cybercrime victimization, with special emphasis on the psychosocial consequences that the deregulated use of these technological devices may entail.

We will then discuss the applications of IQA measures in the design and optimization of advanced image processing algorithms and systems, where we perceive both great promises and major challenges. Finally, we will show how IQA measures could play important roles in an even more extended field of applications and provide a vision of the future.
The Relationship between Personality and Career Decision Making Self Efficacy Among Pra-University Student at Machang, Kelantan.

This study was conducted to explore the differences in personality and level of career decision-making self-efficacy (CDMSE) by gender among pre-university students. Besides, this study also conducted to identify the relationship between personality and CDMSE among pre-university students. This study uses a mixed method design in determining the relationship between personality and self-efficacy in career decision making. The respondent be selected by using simple random sampling method, as 175 student Pre-University and 5 respondents were selected to interview in obtaining qualitative findings. Data was collected by using Big Five Inventory-2 (BFI-2) and Career Decision Making Self-efficacy Scale Short Form (CDMSE-SF). Data analyzed using Statistical Package Social Science 25.0 (SPSS). The results showed no difference between conscientiousness (t(173)=0.280,p<0.05), openness (t(173)=0.613,p<0.05), neuroticism (t(173)=1.434,p<0.05), agreeableness (t(173)=0.857, p<0.05, extraversion (t(173)=-0.559, p<0.05) and level of CDMSE (t(173)=1.558, p<0.05). The finding also revealed that conscientiousness, (r=0.505**, n=175, p<0.05) openness, (r=0.212**, n=175, p<0.05) neuroticism, (r=0.366**, n = 175, p<0.05) and extraversion (r=0.486**, n=175, p<0.05) had a significant relationship with CDMSE among Pre-University students. However, there is no significant relationship between agreeableness and CDMSE (r=0.128, n=175, p<0.05). The result was supported by qualitative findings, which show the relationship between personality and CDMSE. This study is significant for students, counselor, and educators in helping students related to their careers.
Can quasi-static drops climb uphill on an oscillating substrate? - BIFD 2011 -

Everyday experience suggests that, in the absence of a towel, the best way to remove liquid drops from an object is to shake it, so the drops would slide down and, eventually, fall off. In a recent paper, however, Brunet, Eggers, and Deegan [1] have shown experimentally that, on a sloping plate vibrating vertically, drops can actually climb uphill. An attempt to explain the effect of climbing drops was carried out by Benilov [2] who examined the problem using a quasi-static approximation (assuming the oscillations to be slow, so the drop’s shape is determined by the balance of surface tension, gravity, and inertial force). It was argued that the drop can climb uphill provided the time dependence of the plate’s acceleration, a(t), involves narrow/deep ‘troughs’ and wide/low ‘crests’ (or rather ‘plateaus’). However, this wasn’t the case in the experiments of [1] where a(t) was sinusoidal and, thus, had symmetric troughs and crests. Another theoretical study of the results of [1] was carried out by Benilov and Billingham [3]. Not employing the quasi-static approximation, they assumed that the inertial force and gravity are weaker than surface tension, whereas the Reynolds number is large. Within the framework of such a model, drops were shown to indeed be able climb uphill for a sinusoidal a(t). Still, one discrepancy remained: in a significant proportion of the experiments reported in [1], the drops were indeed quasi-static, for which case [2] appears to predict that they cannot climb uphill (which disagrees with the experiments). Another shortcoming of both theoretical studies [2-3] is that they considered two-dimensional drops (where the real-life drops are, of course, three-dimensional. The present work resolves the above discrepancy. It is shown that an asymptotic regime was missed in [2] where quasi-static drops can indeed climb uphill due to interplay between the inertial force and hydrostatic pressure. The results obtained are extended to three-dimensional drops. Finally, it is shown that, if a(t) involves narrow/deep troughs and wide/low plateaus, the drop climbs uphill much faster than that in the case of sinusoidal a(t). REFERENCES
Optimal pacing strategy in competitive athletic performance

The present study was designed to examine the role of central and peripheral fatigue on 4000-m cycling time trial performance by comparing changes in mechanical power output (Ptot) and integrated electromyography (iEMG) in differently paced maximal efforts. Eight well-trained males performed three randomly ordered time trials with different pacing strategies, in which the first 2000 m were manipulated to evoke an increasing, even and decreasing power output profile (SUB, EVEN and SUPRA respectively). Subjects were instructed to finish the last 2000 m of all trials in the shortest time possible. iEMG of the rectus femoris (RF), vastus lateralis (VL) and biceps femoris (BF) muscle, Ptot and gas exchange variables were measured. Anaerobic and aerobic contributions to mechanical power output were calculated from gas exchange data. The increase in Ptot during the SUB-time trials was always associated with an increase in iEMG in all muscles. A decrease in Ptot near the end of the time trials was also marked by an increase in iEMG for all muscles, except for the RF. Comparing the last 2000-m interval with the first, aerobic power output increased for all strategies. Anaerobic power output increased in SUB and decreased in EVEN en SUPRA. The relationship between iEMG and Ptot pattern was consistent with peripheral fatigue rather than central downregulation of Ptot. Specifically anaerobic energy resources seem to be of importance in regulating pacing strategy.
Theoretical Study of Solvent Effects on the Electronic and Thermodynamic Properties of Tetrathiafulvalene (TTF) Molecule Based on DFT

Tetrathiafulvalene () is an organosulfur compound used in the production of molecular devices such as switches, sensors, nonlinear optical devices and rectifiers. In this work, a theoretical study on the effects of solvent on TTF molecule was investigated and reported based on Density Functional Theory (DFT) as implemented in Gaussian 03 package using B3LYP/6-31++G(d,p) basis set. Different solvents were introduced as a bridge to investigate their effects on the electronic structure. The HUMO, LUMO, energy gap, global chemical index, thermodynamic properties, NLO and DOS analysis of the TTF molecule in order to determine the reactivity and stability of the molecule were obtained. The results obtained showed that the solvents have effects on the electronic and non-linear-optical properties of the molecule. The optimized bond length revealed that the molecule has strong bond in gas phase with smallest bond length of about 1. 0834Å than in the rest of the solvents. It was observed that the molecule is more stable in acetonitrile with HOMO-LUMO gap and chemical hardness of 3.6373eV and 1.8187eV respectively. This indicates that the energy gap and chemical hardness of TTF molecule increases with the increase in polarity and dielectric constant of the solvents. The computed results agreed with the results in the literature. The thermodynamics and NLO properties calculation also indicated that TTF molecule has highest value of specific heat capacity (Cv), total dipole moment () and first order hyperpolarizability () in acetonitrile, while acetone has the highest value of entropy and toluene has a slightly higher value of zero point vibrational energy (ZPVE) than the rest of the solvents. The results show that careful selection of the solvents and basis sets can tune the frontier molecular orbital energy gap of the molecule and can be used for molecular device applications.
Cochlear blood supply: an update on anatomy and function

Thorough familiarity with the cochlear blood supply is extremely useful to improve the rate of hearing preservation after pontocerebellar tumor removal and to understand the pathophysiology of sensorineural hearing loss caused by vascular disease. Current knowledge on the cochlear blood supply is reviewed herein. The vascular anatomy of the cochlea shows that preservation of the internal auditory artery is crucial to hearing preservation after pontocerebellar tumor removal. Vascular cochlear partition is relevant to the symptoms of hearing loss due to vascular causes. The close dependency of the endolymphatic potential on the stria vascularis explains the vulnerability of otoacoustic emissions to ischemia. In conclusion, detailed knowledge of cochlear vascular anatomy is essential in order to preserve hearing during pontocerebellar tumor surgery. Evaluations of cochlear blood flow measurements using laser Doppler velocimetry may provide insights into the pathophysiology of sensorineural hearing loss caused by vascular disease.

An interleaved boost DC-DC converter with large conversion ratio

A new PWM dc-dc converter is introduced in which large voltage step-up ratios can be achieved without high duty-cycle, with low voltage and current stress and without transformer. The proposed circuit is an extension of the boost interleaved converter, incorporating a multistage capacitor multiplier. A simple nondissipative snubber can be used reducing the reverse recovery current of the diodes and also obtaining low turn-on and turn-off losses. The modularity of the structure allows the increment of the current, voltage and power levels, using the same range of components and maintaining high efficiency, only increasing the number of series and parallel stages. The paper gives a theoretical analysis, and experimental data on a 400 W example that was built and tested: 24 Vdc input, 200 Vdc output, and 40 kHz switching frequency. The measured performance agreed well with the theoretical predictions and the measured efficiency obtained is equal to 95% at full load.
Real-Time Optimization of Retinal Ganglion Cell Spatial Activity in Response to Epiretinal Stimulation

Retinal prostheses aim to improve visual perception in patients blinded by photoreceptor degeneration. However, shape and letter perception with these devices is currently limited due to low spatial resolution. Previous research has shown the retinal ganglion cell (RGC) spatial activity and phosphene shapes can vary due to the complexity of retina structure and electrode-retina interactions. Visual percepts elicited by single electrodes differ in size and shapes for different electrodes within the same subject, resulting in interference between phosphenes and an unclear image. Prior work has shown that better patient outcomes correlate with spatially separate phosphenes. In this study we use calcium imaging, in vitro retina, neural networks (NN), and an optimization algorithm to demonstrate a method to iteratively search for optimal stimulation parameters that create focal RGC activation. Our findings indicate that we can converge to stimulation parameters that result in focal RGC activation by sampling less than 1/3 of the parameter space. A similar process implemented clinically can reduce time required for optimizing implant operation and enable personalized fitting of retinal prostheses.
Congenital portosystemic shunt concurrent with an atrial septal defect in a Maltese dog

Background: Portosystemic shunt and atrial septal defect (ASD) are generally congenital diseases in dogs. Rarely, dogs with congenital vascular anomalies could be related to other vascular anomalies. Case Description: A 1-year-old male Maltese dog, neutered and weighing 1.7 kg, was brought in for an additional assessment of a congenital portosystemic shunt (CPSS). CPSS was diagnosed as portocaval shunt by computed tomography. Surgical attenuation was performed. Although prognosis after CPSS attenuation was good, the dog was presented with exercise intolerance 1 year after the operation. Thoracic radiographs observed generalized cardiomegaly. Echocardiography revealed pulmonary hypertension and right-to-left shunting ASD. Conclusion: The present study reports a rare case of CPSS concurrent with ASD in a dog. As dogs with CPSS might have been associated with other vascular anomalies; therefore, echocardiography is recommended for early diagnosis of other cardiovascular anomalies.
Influence of operational sex ratio and male age on mating competition intensity in reindeer (Rangifer tarandus)

The operational sex ratio (OSR), the ratio of sexually active males to sexually receptive females, is one of the main measures used to predict the intensity and direction of mating competition, influencing the opportunity for sexual selection. Here, we conducted the first experimental study to investigate how OSR and male age impacts the intensity of mating competition in reindeer (Rangifer tarandus), under semi-natural conditions during the rut. We manipulated OSR on two levels in two enclosures, a female biased treatment (3♂:6♀ = OSR 0.5) and a sex balanced treatment (3♂:3♀ = OSR 1), over 2 years with males from two age groups, and with females of various ages. We found some support for prevailing OSR theory, notably with female intrasexual competition occurring at lower frequencies in OSR 1 than OSR 0.5, and male intrasexual competition occurring at higher frequencies in the older male age group. Courtship behaviour was found to occur at higher frequencies in OSR 1 than OSR 0.5; however, there was no effect of male age. To successfully pass on genes to the next generation, one needs access to mates and winning a competitive bout is not always indicative of successfully accomplishing gene flow. Studies on OSR have the potential to help us understand the drivers behind sexual competition and how best to predict breeding outcomes during a rut.
