Review of Armed Offenders Squad and Special Tactics Group fitness policy for the New Zealand Police : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Exercise and Sport Science at Massey University, Wellington, New Zealand

Phase One: Web based survey questionnaire. Recruitment into the New Zealand Police’s Armed Offenders Squad [AOS] and Special Tactics Group [STG] depends on successful completion of selection courses, as detailed in their respective physical fitness policies. Importantly, these physical assessments must be justified as being relevant and representative of the necessities of job duties. Therefore, as part of a review of the physical fitness policies of the AOS and STG of the New Zealand Police, Phase One of this research sought to objectively determine similarities and relationships between the AOS and STG, and the relevance of physical selection tasks utilised. A web-based survey questionnaire was developed to: 1) provide a demographic profile of the AOS and STG; 2) identify why candidates chose to participate in selection; 3) identify potential barriers for gaining entrance into the AOS and STG; 4) identify physical preparation methods for selection tests; 5) identify troublesome tests; and 6) establish the validity between fitness assessments and the perceived relevance of job demands. A total of 179 AOS (N = 298) and 35 (N = 38) STG members volunteered to participate in the on-line survey document. The main findings revealed that the 12 minute bridge test had the lowest perceived relevance of all selection tests, while the rope pull-up had moderate perceived relevance but was coupled with a high failure rate. This provided evidence to further research the aforementioned assessments in Phase Two of this project. Abstract Review of AOS and STG fitness policy for NZ Police 2 Phase Two: Analysis of the rope pull-up and twelve minute rotational bridge. The rope pull-up and 12 minute bridge test are physical assessments utilised to identify whether STG members possess appropriate levels of physical fitness required to perform their role. Due to a lack of empirical research, and Phase One findings, this study sought to: 1) determine whether the rope pull-up is a suitable assessment tool to assess operational climbing ability; and 2) determine whether the 12 minute rotational bridge test is a safe and suitable assessment of core endurance. Nineteen STG members (mean ± SD; 40 ± 5 y, 184 ± 5 cm, 93.6 ± 7.4 kg, 25.4 ± 1.9 kg·m²) volunteered to participate in this research. Surface electromyography was utilised to measure peak muscle activity of the brachioradialis, biceps brachii, mid-deltoid, upper pectoralis major, mid-trapezius, lower trapezius, latissimus dorsi and infraspinatus during rope pull-up, ladder climb and rope climb tasks. Average muscle activity and signal frequency of the rectus abdominis, external oblique, internal oblique, mutlifidus, lumbar erector spinae, thoracic erector spinae, latissimus dorsi and mid-deltoid were measured during the 12 minute bridge test. Results revealed significantly higher activation of the pectoralis major during the ladder climb when compared to the rope pull-up (81.2 vs. 47.1 %MVIC), and of the pectoralis major (102.6 vs. 47.1 %MVIC) and infraspinatus (81.9 vs. 57.4 %MVIC) during the rope climb, when compared to the rope pull-up (all, P .05), indicated that muscular fatigue was minimal. Based on the present study, the rope pull-up was deemed non-appropriate to assess operational climbing ability; while the rotational bridge served as a practical endurance assessment of all major muscles involved in core stability, with the 12 minute duration not likely to cause fatigue related injury

Partial report is the wrong paradigm

Is consciousness independent of the general-purpose information processes known as ‘cognitive access’? The dominantmethodology for supporting this independence hypothesis appeals to partial report experiments as evidence for perceptual consciousness in the absence of cognitive access. Using a standard model of evidential support, and reviewing recent elaborations of the partial report paradigm, this article argues that the paradigm has the wrong structure to support the independence hypothesis. Like reports in general, a subject’s partial report is evidence that she is conscious of information only where that information is cognitively accessed. So partial report experiments could dissociate consciousness from cognitive access only if there were uncontroversial evidence forconsciousness which did not imply reportability. There is no such evidence. An alternative, broadly Marrian methodology for supporting the independence hypothesis is suggested, and some challenges to it outlined. This methodology does not require experimental evidence for consciousness in the absence of cognitive access. Instead it focuses on a function of perceptual consciousness when a stimulus is cognitively accessed. If the processes best suited to implement this function exclude cognitive access, the independence hypothesis will be supported. One relevant function of consciousness may be reflected in reason-based psychological explanations of a subject’s behaviour

Carbon Nanotube Bonding Strength Enhancement Using Metal "Wicking" Process

Carbon nanotubes grown from a surface typically have poor bonding strength at the interface. A process has been developed for adding a metal coat to the surface of carbon nano tubes (CNTs) through a wicking process, which could lead to an enhanced bonding strength at the interface. This process involves merging CNTs with indium as a bump-bonding enhancement. Classical capillary theory would not normally allow materials that do not wet carbon or graphite to be drawn into the spacings by capillary action because the contact angle is greater than 90 degrees. However, capillary action can be induced through JPL's ability to fabricate oriented CNT bundles to desired spacings, and through the use of deposition techniques and temperature to control the size and mobility of the liquid metal streams and associated reservoirs. A reflow and plasma cleaning process has also been developed and demonstrated to remove indium oxide, and to obtain smooth coatings on the CNT bundles

Bump Bonding Using Metal-Coated Carbon Nanotubes

Bump bonding hybridization techniques use arrays of indium bumps to electrically and mechanically join two chips together. Surface-tension issues limit bump sizes to roughly as wide as they are high. Pitches are limited to 50 microns with bumps only 8-14 microns high on each wafer. A new process uses oriented carbon nanotubes (CNTs) with a metal (indium) in a wicking process using capillary actions to increase the aspect ratio and pitch density of the connections for bump bonding hybridizations. It merges the properties of the CNTs and the metal bumps, providing enhanced material performance parameters. By merging the bumps with narrow and long CNTs oriented in the vertical direction, higher aspect ratios can be obtained if the metal can be made to wick. Possible aspect ratios increase from 1:1 to 20:1 for most applications, and to 100:1 for some applications. Possible pitch density increases of a factor of 10 are possible. Standard capillary theory would not normally allow indium or most other metals to be drawn into the oriented CNTs, because they are non-wetting. However, capillary action can be induced through the ability to fabricate oriented CNT bundles to desired spacings, and the use of deposition techniques and temperature to control the size and mobility of the liquid metal streams and associated reservoirs. This hybridization of two technologies (indium bumps and CNTs) may also provide for some additional benefits such as improved thermal management and possible current density increases

A comparison of limited-stretch models of rubber elasticity

In this paper we describe various limited-stretch models of non-linear rubber elasticity, each dependent on only the first invariant of the left Cauchy-Green strain tensor and having only two independent material constants. The models are described as limited-stretch, or restricted elastic, because the strain energy and stress response become infinite at a finite value of the first invariant. These models describe well the limited stretch of the polymer chains of which rubber is composed. We discuss Gent's model which is the simplest limited-stretch model and agrees well with experiment. Various statistical models are then described: the one-chain, three-chain, four-chain and Arruda-Boyce eight-chain models, all of which involve the inverse Langevin function. A numerical comparison between the three-chain and eight-chain models is provided. Next, we compare various models which involve approximations to the inverse Langevin function with the exact inverse Langevin function of the eight-chain model. A new approximate model is proposed that is as simple as Cohen's original model but significantly more accurate. We show that effectively the eight-chain model may be regarded as a linear combination of the neo-Hookean and Gent models. Treloar's model is shown to have about half the percentage error of our new model but it is much more complicated. For completeness a modified Treloar model is introduced but this is only slightly more accurate than Treloar's original model. For the deformations of uniaxial tension, biaxial tension, pure shear and simple shear we compare the accuracy of these models, and that of Puso, with the eight-chain model by means of graphs and a table. Our approximations compare extremely well with models frequently used and described in the literature, having the smallest mean percentage error over most of the range of the argument

We have previously shown that Notch4 expression was upregulated in various renal cells in human immunodeficiency virus (HIV)-associated nephropathy (HIVAN) patients and rodent models of HIVAN. In this study, we examined whether the Notch pathway can be distinctly activated by HIV-1 gene products and whether Notch4, in particular, can influence disease progression. Using luciferase reporter assays, we did not observe activation of the NOTCH4 promoter with the HIV protein Nef in podocytes. Further, we observed upregulated expression of a gamma secretase complex protein, presenilin 1, but not Notch4, in podocytes infected with an HIV-1 expression construct. To assess the effects of Notch4 on HIVAN disease progression, we engineered Tg26 mice with global deletion of the Notch4 intracellular domain (Notch4dl), which is required for signaling function. These mice (Notch4d1/Tg26+) showed a significant improvement in renal function and a significant decrease in mortality compared to Tg26 mice. Histological examination of kidneys showed that Notch4d1/Tg26+ mice had overall glomerular, tubulointerstitial injury and a marked decrease in interstitial inflammation. A significant decrease in the proliferating cells was observed in the tubulointerstitial compartments of Notch4d1/Tg26+ mice. Consistent with the diminished inflammation, kidneys from Notch4d1/Tg26+ mice also showed a significant decrease in expression of the inflammatory cytokine transcripts Il-6 and Ccl2, as well as the master inflammatory transcription factor NF-κB (Nfkb1 transcripts and p65 protein). These data identify Notch4 as an important mediator of tubulointerstitial injury and inflammation in HIVAN and a potential therapeutic target.National Institutes of Health (R01DK108433 awarded to M.S.
