If the gift and the reciprocation both come from private resources, it is clearly a gift. If what is reciprocated after a gift is given comes from an organization, or is a government resource rather than from “one’s own pocket” then it is most likely a bribe. This study reviews the anthropological literature on gift giving and constructs a typology for examining the gift/bribe distinction in public administration. This classification helps distinguish analytically among different gift practices and clarify conceptual ambiguity of the terms gift and bribe

Pharyngeal pressure-flow analysis (PFA) of high resolution impedance-manometry (HRIM) with calculation of the swallow risk index (SRI) can quantify swallow dysfunction predisposing to aspiration. We explored the potential use of artificial neural networks (ANN) to model the relationship between PFA swallow metrics and aspiration and to predict swallow dysfunction.
Methods
Two hundred consecutive dysphagia patients referred for videofluoroscopy and HRIM were assessed. Presence of aspiration was scored and PFA software derived 13 metrics and the SRI. An ANN was created and optimized over training cycles to achieve optimal classification accuracy for matching inputs (PFA metrics) to output (presence of aspiration on videofluoroscopy). Application of the ANN returned a value between 0.00 and 1.00 reflecting the degree of swallow dysfunction.
Key Results
Twenty one patients were excluded due to insufficient number of swallows (<4). Of 179, 58 aspirated and 27 had aspiration pneumonia history. The SRI was higher in aspirators (aspiration 24 [9, 41] vs no aspiration 7 [2, 18], p < 0.001) and patients with pneumonia (pneumonia 27 [5, 42] vs no pneumonia 8 [3, 24], p < 0.05). The ANN Predicted Risk was higher in aspirators (aspiration 0.57 [0.38, 0.82] vs no aspiration 0.13 [0.4, 0.25], p < 0.001) and in patients with pneumonia (pneumonia 0.46 [0.18, 0.60] vs no pneumonia 0.18 [0.6, 0.49], p < 0.01). Prognostic value of the ANN was superior to the SRI.
Conclusions & Inferences
In a heterogeneous cohort of dysphagia patients, PFA with ANN modeling offers enhanced detection of clinically significant swallowing dysfunction, probably more accurately reflecting the complex interplay of swallow characteristics that causes aspiration

To view a copy of this license, visit http://creativecommons.org/licenses/by/4.0/The application of high-resolution genetic data has revealed that oceanographic connectivity in marine species with planktonic larvae can be surprisingly limited, even in the absence of major barriers to dispersal. Australia’s southern coast represents a particularly interesting system for studying planktonic larval dispersal, as the hydrodynamic regime of the wide continental shelf has potential to facilitate onshore retention of larvae. We used a seascape genetics approach (the joint analysis of genetic data and oceanographic connectivity simulations) to assess population genetic structure and self-recruitment in a broadcast-spawning marine gastropod that exists as a single meta-population throughout its temperate Australian range. Levels of self-recruitment were surprisingly high, and oceanographic connectivity simulations indicated that this was a result of low-velocity nearshore currents promoting the retention of planktonic larvae in the vicinity of natal sites. Even though the model applied here is comparatively simple and assumes that the dispersal of planktonic larvae is passive, we find that oceanography alone is sufficient to explain the high levels of genetic structure and self-recruitment. Our study contributes to growing evidence that sophisticated larval behaviour is not a prerequisite for larval retention in the nearshore region in planktonic-developing species
Effects of Ramipril and Telmisartan on Plasma Concentrations of Low Molecular Weight and Protein Thiols and Carotid Intima Media Thickness in Patients with Chronic Kidney Disease

Although inhibitors of the renin-angiotensin system (RAS) exert salutary effects on blood pressure control and proteinuria in CKD patients, their activity towards traditional and novel oxidative markers is largely unknown. We studied the effects of 6-month treatment with telmisartan versus a combination of telmisartan and ramipril on plasma concentrations of low molecular mass (LMW, including homocysteine and cysteine) and protein thiols (PSH) plasma concentration and their relationships with carotid intima media thickness (IMT), in 24 hypertensive CKD patients (age 60+/-12 years, 8 females and 16 males). Pretreatment PSH concentrations were independently associated with IMT. Neither treatment affected plasma LMW thiols, in both reduced and total form. By contrast, both treatments increased PSH plasma concentrations and reduced IMT, although significant differences were only observed in the combined treatment group. Our results suggest that the beneficial effects of combined RAS inhibitor treatment on IMT in hypertensive CKD patients may be mediated by a reduction of oxidative stress markers, particularly PSH
Immunosuppressive drug assaying: A challenge for renal transplantation in the Northern Territory, Australia

Renal transplant patients of the Northern Territory (NT) of Australia, suffer poor transplant outcomes including graft rejection, infection and increased mortality, therefore requiring stringent immunosuppressive drug assay monitoring. Best practice dictates that drug assay results should be received within 24 hours and at the most no later than 48 hours post blood collection. Assays from the Royal Darwin Hospital (RDH) are processed at an interstate laboratory, therefore prolonging the time to dosage adjustment.
Aims
To assess the time delay that exists between blood sample collection at the Royal Darwin Hospital (RDH) and the faxing of results from an interstate laboratory to RDH.
Methods
We conducted a retrospective audit of immunosuppressive drug assay samples and results between the 4th of January 2013 and the 22nd April 2014. Time delay was divided into intervals: T1: Total time between collections to faxing of results back to RDH, T2: Time between blood collection, sending of samples and reporting at an interstate laboratory, T3: Time between results reporting and the faxing of results back to RDH.
Results
A total of 389 drug assays from 49 renal transplant patients were analysed. Median times in hours (interquartile ranges) were T1=53.48 (31.68-78.55), T2=47.18 (28.80-76.18), T3=2.70 (1.87-3.90). 13.3 per cent of the results led to the requirement for dosage changes with the potential risk of under-dosing or overdosing.
Conclusion
The long median time delay between sample collection and receiving of results illustrates the challenges of immunosuppression in this setting and the need for on-site immunosuppressive drug assaying
Protein hydrolysates produced from rock lobster (Jasus edwardsii) Head: emulsifying capacity and food safety
No full texthis is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.Lobster protein hydrolysates (LPH) were produced by an enzymatic process using a proteinase Alcalase, and a chemical process at strong alkaline condition (pH of 14), from rock lobster head (RLH), respectively. The chemical process recovered about 30% more protein than the enzymatic process (84.9% recovery of total protein in RLH by the chemical process and 54.5% recovery of total protein in RLH by the enzymatic process). The emulsifying capacity of LPH produced by the chemical process (69.7 m2/g) was significantly higher than the emulsifying capacity of the LPH produced by the enzymatic process (20.7 m2/g), and also exceeds the emulsifying capacity of cow gelatine (50.3 m2/g), a commercial emulsifier in the food industry. LPH produced by the chemical process possess 30.3% essential amino acids. This content is comparable with the essential amino acid content of fish protein, a commonly recognized food resource for essential amino acid supplement for human. The content of heavy metals, including inorganic arsenic, of LPH is lower than the standard levels regulated by Food Standard Australia and New Zealand (FSANZ). These results demonstrated the potential value of LPH used as a safe emulsifier with significant nutritional value for the food industry

Emerging evidence from the last 20 years has highlighted a drastic shift in the known epidemiology of CDI, with disease outside of hospitals apparently occurring more frequently and causing severe disease in populations that were thought to be at low risk. This narrative review summarises potential pathways for infection outside of the hospital environment and highlights likely routes of transmission. Further, evidence is presented on potential risk factors for development of disease. Understanding the epidemiology of CDI outside of hospitals is essential to the ability to prevent and control disease in vulnerable populations
Australian Food Safety Policy Changes from a “Command and Control” to an “Outcomes-Based” Approach: Reflection on the Effectiveness of Its Implementation

Over the past decade in Australia, despite advances in microbiological detection and control methods, there has been an increase in the incidence of foodborne illness. Therefore improvements in the regulation and implementation of food safety policy are crucial for protecting public health. In 2000, Australia established a national food safety regulatory system, which included the adoption of a mandatory set of food safety standards. These were in line with international standards and moved away from a “command and control” regulatory approach to an “outcomes-based” approach using risk assessment. The aim was to achieve national consistency and reduce foodborne illness without unnecessarily burdening businesses. Evidence demonstrates that a risk based approach provides better protection for consumers; however, sixteen years after the adoption of the new approach, the rates of food borne illness are still increasing. Currently, food businesses are responsible for producing safe food and regulatory bodies are responsible for ensuring legislative controls are met. Therefore there is co-regulatory responsibility and liability and implementation strategies need to reflect this. This analysis explores the challenges facing food regulation in Australia and explores the rationale and evidence in support of this new regulatory approach. View Full-Tex
Quantitative urinalysis using aggregation-induced emission bioprobes for monitoring chronic kidney disease
No full textOpen Access Article. This article is licensed under a Creative Commons Attribution 3.0 Unported Licence.Early detection and appropriate management of chronic kidney disease can reduce the progression of kidney failure and cardiovascular disease. The urine albumin to creatinine ratio (UACR) test is a standard urine test for identifying individuals at high risk of developing progressive kidney disease. In this study, IDATPE, a novel fluorescent probe with aggregation-induced emission (AIE) features, is successfully developed for creatinine detection and quantitation. An excellent correlation between fluorescent light intensity and creatinine concentration is achieved. In addition, BSPOTPE, a reported excellent AIE bioprobe for human serum albumin (HSA) quantitation, is used together with IDATPE in artificial urine for UACR testing. The mutual interference of HSA and creatinine when the bioprobes are used for quantitation is characterised, with promising results. Further improvements and potential applications in CKD quantitation are highlighted
Reducing the generalised Sudoku problem to the Hamiltonian cycle problem
Get PDFPublishing Services by Elsevier B.V. This is an open access article under the CC BY-NC-ND license (http://creativecommons.org/licenses/by-nc-nd/4.0/).The generalised Sudoku problem with NN symbols is known to be NP-complete, and hence is equivalent to any other NP-complete problem, even for the standard restricted version where NN is a perfect square. In particular, generalised Sudoku is equivalent to the, classical, Hamiltonian cycle problem. A constructive algorithm is given that reduces generalised Sudoku to the Hamiltonian cycle problem, where the resultant instance of Hamiltonian cycle problem is sparse, and has O(N3)O(N3) vertices. The Hamiltonian cycle problem instance so constructed is a directed graph, and so a (known) conversion to undirected Hamiltonian cycle problem is also provided so that it can be submitted to the best heuristics. A simple algorithm for obtaining the valid Sudoku solution from the Hamiltonian cycle is provided. Techniques to reduce the size of the resultant graph are also discussed
