Simultaneous Temperature and Strain Sensing Based on M-Shaped Single Mode Fiber

We propose a novel M-shaped single mode fiber (M-SMF) sensor based on stimulated Brillouin scattering of higher-order acoustic modes for simultaneous temperature and strain measurement. Numerical investigation of longitudinal acoustic modes in the M-SMF shows that multi-peak Brillouin spectrum in M-SMF is contributed by the couplings between the LP<sub>01</sub> optical mode and multiple acoustic modes. The Brillouin characteristics in the M-SMF are compared with those of standard single mode fiber. Utilizing the multi-peak feature of Brillouin gain spectrum, sensing characteristics of the M-SMF under different temperature and strain conditions were studied. Thanks to the widely spaced <inline-formula> <tex-math notation="LaTeX">$L_{01}$ </tex-math></inline-formula> and <inline-formula> <tex-math notation="LaTeX">$L_{02}$ </tex-math></inline-formula> acoustic mode peaks in the Brillouin spectrum of M-SMF, the proposed fiber enables discriminative sensing of temperature and strain at an accuracy of 0.47 °C and <inline-formula> <tex-math notation="LaTeX">$12.3~{\mu \varepsilon }$ </tex-math></inline-formula>, respectively.
Influence of Organisational Learning and Human Resource Outcomes on Commercial Banks’ Performance in Nigeria

Abstract Most service organisations around the world are faced with the challenges of technological innovations and sustainable competitive advantage. To overcome these challenges, an understanding of organisational learning culture and human resource outcome becomes imperative. This study examined the influence of organisational learning culture and human resource (HR) outcomes on organisational performance. Two hypotheses were formulated to examine the extent to which learning and HR outcomes influence performance in the banking industry. The researchers adopted a mixed methods approach, that is, the use of a structured questionnaire (n=250), personal interviews (10 managers), observations (5 days) and other documented evidence (annual reports/statements of accounts for three consecutive years). The study used a convenience sampling technique to select the respondents. The findings revealed that team learning and HR outcomes have a marked influence on organisational performance. This study proposed that there is a strong positive relationship between organisational learning culture and HR outcomes that jointly serve as a better predictor of organisational performance among commercial banks in Nigeria.
ASSOCIATIONS BETWEEN PERSONALITY TRAITS AND AGGRESSION AMONG MALAY ADULT MALE INMATES IN MALAYSIA

Objective: A sizable body of criminology literature has suggested that personality factors are critical to the development of aggressive behaviour. While research on personality focusing on aggression often revolves on "Eynseck Three Factor Model" and "Big Five Model", research on "Alternative Five Factor Model" (AFFM) is rather inadequate. Objective: The present study aimed to examine the association between five types of personality traits and subscales of aggression. Methods: This observational cross-sectional study was conducted in two prisons in Peninsular Malaysia among 198 Malay adult male inmates. The participants were selected based on the purposive sampling method fro m those who were convicted for various types of crime. Two psychometric instruments adapted to the Malaysian context were used: Malay version of Zuckerman-Kuhlman Personality Questionnaire-40-Cross Culture (ZKPQ-M-40-CC) and Aggression Questionnaire (AQ-M). Pearson correlation coefficient test was conducted to determine the association between five types of personality traits and subscales of aggression. Results: The results showed that there was a significant association between certain types of personality traits and subscales of aggression. The results were discussed in relation to theory and the context of crime. Conclusion: There is evidence that personality traits are linked to aggressive behaviour which may lead a person to commit offenses.

Financial implications of choice of dialysis type of the revised Medicare payment system: an economic analysis.

BACKGROUND In 2011, the Medicare Improvements for Patients and Providers Act replaced the case-mix-adjusted composite payment system for Medicare outpatient dialysis facilities with a bundled end-stage renal disease prospective payment system (PPS). We assessed the economic implications for modality choice of the revised Medicare payment system. STUDY DESIGN Microeconomic analyses. SETTING & POPULATION Patients eligible for dialysis in the United States. MODEL, PERSPECTIVE, & TIMEFRAME The perspective of this analysis is that of a financial administrator of a representative dialysis center in the United States. Data were obtained from the Medicare Payment Advisory Commission, the US Renal Data System, the DOPPS (Dialysis Outcomes and Practice Patterns Study) Practice Monitor, the US Bureau of Labor Statistics, and Medicare fee schedules. INTERVENTIONS Recently implemented end-stage renal disease PPS versus the prior case-mix composite payment system. OUTCOMES Medicare payment per month, center fixed and variable costs per month, net difference in revenue and variable costs (direct contribution), and net difference in revenue and total costs (operating margin). RESULTS The direct contribution and operating margin for in-center hemodialysis and peritoneal dialysis are expected to be positive under the new bundled PPS. For Medicare fiscal intermediaries/administrators, paid treatments for home hemodialysis vary from 3.2 to more than 4.8 per week. The direct contribution and operating margin are expected to be negative for home hemodialysis if the number of paid treatments is similar between in-center and home hemodialysis; they are almost identical when the number of paid treatments increases for home hemodialysis by approximately 1 per week. LIMITATIONS Experience across centers and intermediaries/administrators may vary. Sensitivity analyses were conducted to assess the robustness of findings and determine which variables most influenced results. CONCLUSIONS The new bundled PPS created a financial incentive for increased use of peritoneal dialysis. Use of home hemodialysis may be influenced by number of paid treatments per week.
Error removal in microchip-synthesized DNA using immobilized MutS

The development of economical de novo gene synthesis methods using microchip-synthesized oligonucleotides has been limited by their high error rates. In this study, a low-cost, effective and improved-throughput (up to 32 oligos per run) error-removal method using an immobilized cellulose column containing the mismatch binding protein MutS was produced to generate high-quality DNA from oligos, particularly microchip-synthesized oligonucleotides. Error-containing DNA in the initial material was specifically retained on the MutS-immobilized cellulose column (MICC), and error-depleted DNA in the eluate was collected for downstream gene assembly. Significantly, this method improved a population of synthetic enhanced green fluorescent protein (720 bp) clones from 0.93% to 83.22%, corresponding to a decrease in the error frequency of synthetic gene from 11.44/kb to 0.46/kb. In addition, a parallel multiplex MICC error-removal strategy was also evaluated in assembling 11 genes encoding ∼21 kb of DNA from 893 oligos. The error frequency was reduced by 21.59-fold (from 14.25/kb to 0.66/kb), resulting in a 24.48-fold increase in the percentage of error-free assembled fragments (from 3.23% to 79.07%). Furthermore, the standard MICC error-removal process could be completed within 1.5 h at a cost as low as $0.374 per MICC.
Identification of the template binding polypeptide in the pea chloroplast transcriptional complex

We have identified the template-binding polypeptide in the pea chloroplast transcriptional complex by photoaffinity labelling. This polypeptide has an apparent molecular weight of about 150 kDa and binds to both, chloroplast ribosomal (16S rRNA) and messenger (psbA) promoters. The 16S rRNA and psbA promoters were amplified from chloroplast DNA by the polymerase chain reaction and labelled with a photoactive analogue of TTP, 5-bromodeoxy UTP, as well as with alpha-32P-dCTP. Using the filter-binding assay, the conditions for binding of the RNA polymerase complex to chloroplast promoters were optimized. The polypeptide directly interacting with the template was photo-crosslinked to it and resolved by denaturing gel electrophoresis. The photoaffinity labelling of the 150 kDa polypeptide was dependent on photoactivation by UV irradiation, and the presence of chloroplast promoters. Competition experiments showed that the protein formed a strong interaction with the plastid promoters which could not be displaced by lambda-phage DNA or synthetic polynucleotides. The photo-crosslinked and nuclease-treated promoter-polypeptide complex was resistant to further digestion with DNase and RNase, but could be hydrolyzed by Proteinase K. Binding of the promoters by the 150 kDa polypeptide could not be surpressed by transcription inhibitors like rifampicin and alpha-amanitin. However, heparin (0.001%) inhibited the formation of the enzyme-promoter complex, and interfered with the photoaffinity labelling of the 150 kDa polypeptide. The extent of photoaffinity labelling of 150 kDa polypeptide exhibits some degree of correlation to total transcriptional activity under various salt concentrations. The results demonstrate that the 150 kDa polypeptide is a functional template binding polypeptide of the pea chloroplast transcription complex.
Life Course Influences on African American Men's Depression

What are the processes from adolescence to adulthood that shape the mental health prospects of African American males? This research considers factors over the life course that specifically affect levels of depression in Black men. Regarding how processes that contribute to adult depression differ by race, previous research on depression has been limited in three important ways. First, relatively little research has been done on how factors over the life course influence depression in African Americans, and even less research has specifically investigated the case of African American males. Second, because studies of depression tend to rely on crosssectional data collected at a single time point, it is very difficult to know which past elements of individuals' lives contribute to current levels of depression. Third, studies typically use pooled samples to assess the effects of factors on the mental health outcomes of African Americans. It is possible that with large sample sizes, even controlling for race, that the effects of variables pivotal to understanding the status of African American males are masked or exaggerated. Given the disproportionate number of psychosocial stressors faced by African American males (Gibbs, 1993) compared to their White counterparts, it is especially important to clearly understand how the processes revealed in subsample analyses may differ from those in a pooled sample. The current study contributes to our knowledge of the factors that mold the mental
Microstructure and properties of CoCrNi medium-entropy alloy produced by gas atomization and spark plasma sintering

A homogeneous structured CoCrNi medium-entropy alloy was synthesized by gas atomization and spark plasma sintering (SPS). The mechanical properties, corrosion resistance, and magnetic properties were reported in this study. The as-atomized CoCrNi MEA powder, with a spherical morphology in shape and a mean particle diameter of 61 µm, consisted of a single face-centered cubic (FCC) phase with homogeneous distributions of Co, Cr, and Ni elements. Also, the cross-sectional microstructure of powder particles gradually transformed from fully cellular structure into equiaxed-type structure with increasing particle size. After being sintered by SPS, the CoCrNi MEA consisted of a single FCC phase with a mean grain size of 20.8 µm. Meanwhile, the CoCrNi MEA can capable of offering an ultimate tensile strength of 799 MPa, yield strength of 352 MPa, elongation of 53.6%, and hardness of 195.3 HV. In addition, this MEA showed superior corrosion resistance to that of 304 SS (stainless steel) in both 0.5 mol/L HCl and 1 mol/L NaOH solutions. The magnetization loop indicated that this MEA has good soft magnetic properties.
Effects of Lumbosacral Spinal Cord Epidural Stimulation for Standing after Chronic Complete Paralysis in Humans

Sensory and motor complete spinal cord injury (SCI) has been considered functionally complete resulting in permanent paralysis with no recovery of voluntary movement, standing or walking. Previous findings demonstrated that lumbosacral spinal cord epidural stimulation can activate the spinal neural networks in one individual with motor complete, but sensory incomplete SCI, who achieved full body weight-bearing standing with independent knee extension, minimal self-assistance for balance and minimal external assistance for facilitating hip extension. In this study, we showed that two clinically sensory and motor complete participants were able to stand over-ground bearing full body-weight without any external assistance, using their hands to assist balance. The two clinically motor complete, but sensory incomplete participants also used minimal external assistance for hip extension. Standing with the least amount of assistance was achieved with individual-specific stimulation parameters, which promoted overall continuous EMG patterns in the lower limbs’ muscles. Stimulation parameters optimized for one individual resulted in poor standing and additional need of external assistance for hip and knee extension in the other participants. During sitting, little or negligible EMG activity of lower limb muscles was induced by epidural stimulation, showing that the weight-bearing related sensory information was needed to generate sufficient EMG patterns to effectively support full weight-bearing standing. In general, electrode configurations with cathodes selected in the caudal region of the array at relatively higher frequencies (25–60 Hz) resulted in the more effective EMG patterns for standing. These results show that human spinal circuitry can generate motor patterns effective for standing in the absence of functional supraspinal connections; however the appropriate selection of stimulation parameters is critical.
Pet191 Is a Cytochrome c Oxidase Assembly Factor in Saccharomyces cerevisiae

ABSTRACT The twin-Cx9C motif protein Pet191 is essential for cytochrome c oxidase maturation. The motif Cys residues are functionally important and appear to be present in disulfide linkages within a large oligomeric complex associated with the mitochondrial inner membrane. The import of Pet191 differs from that of other twin-Cx9C motif class of proteins in being independent of the Mia40 pathway.
Non‐animal assessment of skin sensitization hazard: Is an integrated testing strategy needed, and if so what should be integrated?

There is an expectation that to meet regulatory requirements, and avoid or minimize animal testing, integrated approaches to testing and assessment will be needed that rely on assays representing key events (KEs) in the skin sensitization adverse outcome pathway. Three non‐animal assays have been formally validated and regulatory adopted: the direct peptide reactivity assay (DPRA), the KeratinoSens™ assay and the human cell line activation test (h‐CLAT). There have been many efforts to develop integrated approaches to testing and assessment with the “two out of three” approach attracting much attention. Here a set of 271 chemicals with mouse, human and non‐animal sensitization test data was evaluated to compare the predictive performances of the three individual non‐animal assays, their binary combinations and the “two out of three” approach in predicting skin sensitization potential. The most predictive approach was to use both the DPRA and h‐CLAT as follows: (1) perform DPRA – if positive, classify as sensitizing, and (2) if negative, perform h‐CLAT – a positive outcome denotes a sensitizer, a negative, a non‐sensitizer. With this approach, 85% (local lymph node assay) and 93% (human) of non‐sensitizer predictions were correct, whereas the “two out of three” approach had 69% (local lymph node assay) and 79% (human) of non‐sensitizer predictions correct. The findings are consistent with the argument, supported by published quantitative mechanistic models that only the first KE needs to be modeled. All three assays model this KE to an extent. The value of using more than one assay depends on how the different assays compensate for each other's technical limitations. Copyright © 2017 John Wiley & Sons, Ltd.
Life-course socio-economic factors, skin colour and abdominal obesity in adulthood in a Brazilian birth cohort

Abstract Objective Obesity is an increasingly prevalent nutritional disorder throughout the world. In particular, abdominal obesity is associated with cardiovascular and metabolic risk. The present study aimed to evaluate the effects of skin colour and life-course socio-economic indicators on waist circumference (WC), hip circumference (HC) and waist:hip ratio (WHR) in young adults. Design Population-based birth cohort study. Individuals born in 1982 in Pelotas (southern Brazil) were visited on a number of occasions from birth to age 23–24 years. A sample of the cohort was sought in 2006 and 972 individuals were located. The analysis was restricted to individuals with complete data available (442 males, 414 females). Results In men, family income at birth and in 2004–5 were positively associated with WC and HC, but not with WHR. Regardless of current income, men born to wealthier families had larger WC and HC as adults. Skin colour was not associated with any of the outcomes. In women, early poverty was associated with smaller HC, and current poverty with larger WC. Poverty at any age thus led to higher WHR. Black women had larger WC and HC than white women, but there were no differences in WHR. All the associations were partially mediated by education and behavioural variables. Conclusions The effects of early socio-economic position on WC and HC persist even after adjustment for adult socio-economic position, highlighting the importance of interventions during the first years of life.
Sustaining improvement in schools in challenging circumstances: a study of successful practice

Achieving sustainable improvement in schools facing challenging circumstances remains a major challenge for policy-makers and practitioners alike. This paper analyses the strategies used within a group of English secondary schools that have succeeded in increasing and sustaining attainment levels over time in order to learn more about the factors that are associated with success. The evidence presented does not lead to a ‘recipe’. Rather it suggests that the most appropriate way forward is to focus on determining the right sort of ‘ingredients’, mixed to suit the contexts and circumstances of individual schools.
Embedding and integrating language and academic skills: An innovative approach

A growing body of research into the provision of learning support suggests that good practice is exemplified by the integration of language and academic skills (LAS) into specifically targeted core discipline units. There are many reasons offered: that contextualised support picks up weaker students who commonly fail to self-select for voluntary workshops; that students favour contextualised workshops over general workshops, often perceiving the latter to have little relevance to them; that the number of students in Australian universities with English as an additional language (EAL) has increased markedly over the past decade; and that in some units the delivery of contextualised support serves to “up-skill” academic staff. The authors of this paper argue that integrated learning support makes good use of limited resources for all stakeholders: discipline academics, learning advisors and students. The paper explores the experiences of these stakeholders in a core management unit of the MBA at Edith Cowan University over a period of three semesters. It outlines the various tasks involved in this innovative embedding project both in terms of team meetings for the discipline staff and learning advisor, and class time allocated to LAS development. It also evaluates the benefits through student feedback and interviews with members of the embedding team. The authors conclude that the approach taken in this project was effective in supporting incremental, discipline-specific LAS development for students and in raising awareness among discipline teaching staff of the importance of LAS development.
Hold-In, Pull-In, and Lock-In Ranges of PLL Circuits: Rigorous Mathematical Definitions and Limitations of Classical Theory

The terms hold-in, pull-in (capture), and lock-in ranges are widely used by engineers for the concepts of frequency deviation ranges within which PLL-based circuits can achieve lock under various additional conditions. Usually only non-strict definitions are given for these concepts in engineering literature. After many years of their usage, F. Gardner in the 2nd edition of his well-known work, Phaselock Techniques, wrote “There is no natural way to define exactly any unique lock-in frequency” and “despite its vague reality, lock-in range is a useful concept. ” Recently these observations have led to the following advice given in a handbook on synchronization and communications: “We recommend that you check these definitions carefully before using them. ” In this survey an attempt is made to discuss and fill some of the gaps identified between mathematical control theory, the theory of dynamical systems and the engineering practice of phase-locked loops. It is shown that, from a mathematical point of view, in some cases the hold-in and pull-in “ranges” may not be the intervals of values but a union of intervals and thus their widely used definitions require clarification. Rigorous mathematical definitions for the hold-in, pull-in, and lock-in ranges are given. An effective solution for the problem on the unique definition of the lock-in frequency, posed by Gardner, is suggested.
Space Structure and Clustering of Categorical Data

Learning from categorical data plays a fundamental role in such areas as pattern recognition, machine learning, data mining, and knowledge discovery. To effectively discover the group structure inherent in a set of categorical objects, many categorical clustering algorithms have been developed in the literature, among which k-modes-type algorithms are very representative because of their good performance. Nevertheless, there is still much room for improving their clustering performance in comparison with the clustering algorithms for the numeric data. This may arise from the fact that the categorical data lack a clear space structure as that of the numeric data. To address this issue, we propose, in this paper, a novel data-representation scheme for the categorical data, which maps a set of categorical objects into a Euclidean space. Based on the data-representation scheme, a general framework for space structure based categorical clustering algorithms (SBC) is designed. This framework together with the applications of two kinds of dissimilarities leads two versions of the SBC-type algorithms. To verify the performance of the SBC-type algorithms, we employ as references four representative algorithms of the k-modes-type algorithms. Experiments show that the proposed SBC-type algorithms significantly outperform the k-modes-type algorithms.
