A new method for deriving priority weights by extracting consistent numerical-valued matrices from interval-valued fuzzy judgement matrix

It is important to derive priority weights from interval-valued fuzzy preferences when a pairwise comparative mechanism is used. By focusing on the significance of consistency in the pairwise comparison matrix, two numerical-valued consistent comparison matrices are extracted from an interval fuzzy judgement matrix. Both consistent matrices are derived by solving the linear or nonlinear programming models with the aid of assessments from Decision Makers (DMs). An interval priority weight vector from the extracted consistent matrices is generated. In order to retain more information hidden in the intervals, a new probability-based method for comparison of the interval priority weights is introduced. An algorithm for deriving the final priority interval weights for both consistent and inconsistent interval matrices is proposed. The algorithm is also generalized to handle the pairwise comparison matrix with fuzzy numbers. The comparative results from the five examples reveal that the proposed method, as compared with eight existing methods, exhibits a smaller degree of uncertainty pertaining to the priority weights, and is also more reliable based on the similarity measure. © 2014 Elsevier Inc.

Do we know how to design effective health coaching interventions: a systematic review of the state of the literature

 Objective. To systematically review health coaching interventions regarding effectiveness of health coaching for specific outcomes, optimal intervention approaches, and identification of specific techniques associated with effectiveness.
Data Source. Articles were sourced from CINAHL, Global Health, PsycINFO, Academic Search Complete, Health Source, Psychology and Behavioral Sciences Collection, and Medline.
Study Inclusion and Exclusion Criteria. Randomized controlled trials were included if the study (1) employed health coaching according to a predefined criterion; (2) clearly reported the use of health coaching; or (3) incorporated the use of coaching.

Data Extraction. Aims, participants, approach, behavior change techniques (BCTs), and findings pertaining to each study were summarized. BCTs were classified according to the CALO-RE taxonomy.

Data Synthesis. Data were synthesized by cross-tabulation of BCTs with study outcomes.
Results. Fifteen of 16 eligible studies reported a positive intervention effect in at least one outcome. Nine studies (56%) did not define health coaching; the number of intervention sessions provided ranged from 2 to 48; and in three studies, one or more intervention details were unclear. It was hence difficult to synthesize the studies to adequately address our research questions.
Conclusion. Health coaching is a promising strategy for health improvements; however, future research should ensure clarity in reporting intervention details, clearer definitions of health coaching/theoretical bases, consistency in reporting BCTs, and the inclusion of process variables as outcome measures.

On the determination of the number of factors using information criteria with data-driven penalty

As is well known, when using an information criterion to select the number of common factors in factor models the appropriate penalty is generally indetermine in the sense that it can be scaled by an arbitrary constant, c say, without affecting consistency. In an influential paper, Hallin and Liška (J Am Stat Assoc102:603–617, 2007) proposes a data-driven procedure for selecting the appropriate value of c. However, by removing one source of indeterminacy, the new procedure simultaneously creates several new ones, which make for rather complicated implementation, a problem that has been largely overlooked in the literature. By providing an extensive analysis using both simulated and real data, the current paper fills this gap.

A non-contact measurement system for the range of motion of the hand

An accurate and standardised tool to measure the active range of motion (ROM) of the hand is essential to any progressive assessment scenario in hand therapy practice. Goniometers are widely used in clinical settings for measuring the ROM of the hand. However, such measurements have limitations with regard to inter-rater and intra-rater reliability and involve direct physical contact with the hand, possibly increasing the risk of transmitting infections. The system proposed in this paper is the first non-contact measurement system utilising Intel Perceptual Technology and a Senz3D Camera for measuring phalangeal joint angles. To enhance the accuracy of the system, we developed a new approach to achieve the total active movement without measuring three joint angles individually. An equation between the actual spacial position and measurement value of the proximal inter-phalangeal joint was established through the measurement values of the total active movement, so that its actual position can be inferred. Verified by computer simulations, experimental results demonstrated a significant improvement in the calculation of the total active movement and successfully recovered the actual position of the proximal inter-phalangeal joint angles. A trial that was conducted to examine the clinical applicability of the system involving 40 healthy subjects confirmed the practicability and consistency in the proposed system. The time efficiency conveyed a stronger argument for this system to replace the current practice of using goniometers.

The effect of transition to specialty practice programs on Australian emergency nurses' professional development, recruitment and retention

BACKGROUND: To date, emergency nursing Transition to Specialty Practice Program (TSPP) evaluations have been single-site observational studies. The aim of this paper was to examine the professional development, recruitment and retention outcomes of Australian emergency nursing TSPPs. METHODS: An explanatory sequential design was used. Data were collected via online surveys and interviews of emergency Nurse Unit Managers and Nurse Educators. Survey data from EDs with TSPPs and EDs without TSPPs were compared. Qualitative data were analysed using content analysis. RESULTS: Data were collected from 118 EDs, and 13 interviews. TSPPs were offered in 72.1% of EDs. EDs with TSPPs had higher proportions of nurses with postgraduate qualifications (Mdn 28.3% vs. 22.1%, p=0.45) and Clinical Specialists (Mdn 16.4% vs. 6.3%, p=0.04). The median proportion of currently rostered nurses with TSPP completion was 34.2% in EDs with TSPPs introduced in 2000-2005 indicating ED high levels of retention. CONCLUSION: Emergency nursing TSPPs have had a positive effect on nursing professional development, recruitment and retention. To ensure consistency in outcomes and optimise reliability of emergency nursing skills and knowledge, a national emergency nursing TSPP framework is needed.

Disciplinary proceedings against doctors who abuse controlled substances

Study examined 27 reports from disciplinary tribunals against medical practitioners who abused narcotic analgesics (often combined with other drugs of addiction) between 2010 and 2015. The study covered all States and Territories except Tasmania (no reports were accessible for this jurisdiction. The reports revealed that 12 medical practitioners were in their 40s; five in their 30s; and one person still in the 20s. Although majority were General Practitioners (15 out of 27), other medical specialties were also represented. Self-administered Pethidine was the most prevalent opioid (11 out of 27), and was the only drug used alone. Morphine was self-administered by six doctors; the same number used high doses of Panadeine Forte, Codeine and Codeine Phosphate, and Fentanyl was abused by five doctors. Surprisingly, fewer medical practitioners appear to use such opiates such as Propofol, Tramadol and Tramol, Oxycodone and Endone. The examination of cases suggests lack of consistency in the imposition of professional sanctions and penalties by the relevant tribunals. The study concludes that disciplinary tribunals should apply the test of proportionality in the form of ‘reasonable necessity’ when deciding whether to remove or suspend the addicted medical practitioner from the Register.

Comparison of medication policies to guide nursing practice across seven Victorian health services

Objectives The objective of this paper is to review and compare the content of medication management policies across seven Australian health services located in the state of Victoria. Methods The medication management policies for health professionals involved in administering medications were obtained from seven health services under one jurisdiction. Analysis focused on policy content, including the health service requirements and regulations governing practice. Results and Conclusions The policies of the seven health services contained standard information about staff authorisation, controlled medications and poisons, labelling injections and infusions, patient self-administration, documentation and managing medication errors. However, policy related to individual health professional responsibilities, single- and double-checking medications, telephone orders and expected staff competencies varied across the seven health services. Some inconsistencies in health professionals' responsibilities among medication management policies were identified. What is known about the topic? Medication errors are recognised as the single most preventable cause of patient harm in hospitals and occur most frequently during administration. Medication management is a complex process involving several management and treatment decisions. Policies are developed to assist health professionals to safely manage medications and standardise practice; however, co-occurring activities and interruptions increase the risk of medication errors. What does this paper add? In the present policy analysis, we identified some variation in the content of medication management policies across seven Victorian health services. Policies varied in relation to medications that require single- and double-checking, as well as by whom, nurse-initiated medications, administration rights, telephone orders and competencies required to check medications. What are the implications for practitioners? Variation in medication management policies across organisations is highlighted and raises concerns regarding consistency in governance and practice related to medication management. Lack of practice standardisation has previously been implicated in medication errors. Lack of intrajurisdictional concordance should be addressed to increase consistency. Inconsistency in expectations between healthcare services may lead to confusion about expectations among health professionals moving from one healthcare service to another, and possibly lead to increased risk of medication errors.

The personality behind cheating: behavioural types and the feeding ecology of cleaner fish

The complex mutualistic relationship between the cleaner fish (Labroides dimidiatus) and their 'clients' in many reef systems throughout the world has been the subject of debate and research interest for decades. Game-theory models have long struggled with explaining how the mixed strategies of cheating and honesty might have evolved in such a system and while significant efforts have been made theoretically, demonstrating the nature of this relationship empirically remains an important research challenge. Using the experimental framework of behavioural syndromes, we sought to quantitatively assess the relationship between personality and the feeding ecology of cleaner fish to provide novel insights into the underlying mechanistic basis of cheating in cleaner-client interactions. First, we observed and filmed cleaner fish interactions with heterospecifics, movement patterns and general feeding ecology in the wild. We then captured and measured all focal individuals and tested them for individual consistency in measures of activity, exploration and risk taking (boldness) in the laboratory. Our results suggest a syndrome incorporating aspects of personality and foraging effort are central components of the behavioural ecology of L. dimidiatus on the Great Barrier Reef. We found that individuals that exhibited greater feeding effort tended to cheat proportionately less and move over smaller distances relative to bolder more active, exploratory individuals. Our study demonstrates for the first time that individual differences in personality might be mechanistically involved in explaining how the mixed strategies of cheating and honesty persist in cleaner fish mutualisms.

Internal consistency and validity of the Stroke Impact Scale 2.0 (SIS 2.0) and SIS - 16 in an Australian sample

Background and Purpose: The impact of stroke is multidimensional however standard stroke measures do not discriminate well when stroke patients are less physically impaired. The Stroke Impact Scale 2.0 (SIS 2.0) is a multidimensional measure of the impact of stroke but its'' psychometric properties require further testing. The SIS-16 is a measure of physical functioning designed to be more sensitive to differences in physical functioning than current stroke outcome measures but there is only preliminary information detailing its'' reliability and validity. The current study examined the internal consistency and validity of the SIS 2.0 and SIS-16 in an Australian sample of stroke patients. Methods: The SIS 2.0, SIS-16, World Health Organization Bref-Scale (WHOQOL-BREF) and Zung''s Self-Rating Depression Scale (SDS) were completed by 74 stroke patients in rural Victoria, Australia.
Results: The item convergent validity index indicated good item convergence of the SIS-16 and SIS 2.0 domains. The item discriminant validity index had only adequate divergence for most SIS 2.0 domains. Internal consistencies of the SIS-16 and SIS 2.0 domains were acceptable (agr = 0.87–0.95). Correlations between the SIS-16 and SIS 2.0 and the WHOQOL-BREF and SDS supported the convergent and discriminant validity of the SIS-16 and all the dimensions of the SIS 2.0 except lsquoParticipationrsquo which lacked discriminant validity. Conclusions: The SIS 2.0 and SIS-16 had good psychometric properties with support for the internal consistency and validity of both measures.

The consistency of false suggestions moderates children`s reports of a single instance of a repeated event: predicting increases and decreases in suggestibility.

Participants (6- and 7-year-olds, N = 130) participated in classroom activities four times. Children were interviewed about the final occurrence (target event) either 1 week or 4 weeks later, during which half of the event items were described inaccurately. Half of these suggestions were consistent with the theme of the detail across the occurrences (e.g., always sat on a kind of floor mat) or were inconsistent (e.g., sat on a chair). When memory for the target event was tested 1 day later, children falsely recognized fewer inconsistent suggestions than consistent suggestions, especially compared with a control group of children who experienced the event just one time. Furthermore, the longer delay reduced accuracy only for consistent suggestions. Source-monitoring ability was strongly and positively related to resistance to suggestions, and encouraging children to identify the source of false suggestions allowed them to retract a significant proportion of their reports of inconsistent suggestions but not of consistent suggestions. The results suggest that the gist consistency of suggestions determines whether event repetition increases or decreases suggestibility.

Extensible detection and indexing of highlight events in broadcasted sports video

Content-based indexing is fundamental to support and sustain the ongoing growth of broadcasted sports video. The main challenge is to design extensible frameworks to detect and index highlight events. This paper presents: 1) A statistical-driven event detection approach that utilizes a minimum amount of manual knowledge and is based on a universal scope-of-detection and audio-visual features; 2) A semi-schema-based indexing that combines the benefits of schema-based modeling to ensure that the video indexes are valid at all time without manual checking, and schema-less modeling to allow several passes of instantiation in which additional elements can be declared. To demonstrate the performance of the events detection, a large dataset of sport videos with a total of around 15 hours including soccer, basketball and Australian football is used.
