A proposed definition of the engineering methodology

BACKGROUND An adequately concise and accurate definition of the profession of engineering that can simultaneously encompass a majority of the profession and be reasonably understood by a majority of society arguably remains as an elusive goal yet to be attained.While numerous definitions of the profession exist they tend to describe specific methods or approaches deployed in the practice of engineering rather than be suitably descriptive of the profession of engineering.The lack of an adequate, accurate and relevant definition of the profession of engineering has, and continues to, present disadvantages to the profession. While acknowledging this problem the profession continues to rely on existing inadequate, inaccurate, or irrelevant definitions of itself as it struggles to attain the degree of awareness, recognition, and appreciation of its significant benefits that directly impact society and the individual.Accordingly in many countries the choice of engineering as a career path often ranks below other profession choices such as medicine, law, and management - especially with adolescent girls. Also the relevance and role of professional engineering in socio-economic and socio-political contexts is often undervalued or neglected – especially in national and international policy discussions and development.PURPOSETo provide a clear, concise, and accurate definition of the profession of engineering that is acceptable for most, if not all, major stakeholders.METHOD A review of historical and contemporary definitions of professional engineering is provided. Using Koen’s definition of the engineering method in conjunction with Shulman’s set of characteristics common to professions a more generic definition is derived that seeks to simultaneously accommodate the homogenous multi-disciplinary attributes of professional engineering as well as accommodate the discipline specific attributes.RESULTS A proposed definition of the engineering methodology has been developed. A background introduction and justified derivation is provided for the proposed definition.CONCLUSIONS The limitations and inadequacies of historical and contemporary definitions of professional engineering have been considered. Using Koen’s definition as a basis a more generic multi-disciplinary and more contemporary definition is derived and presented. The goal of the proposed definition of the engineering methodology is to provide a more concise, more accurate, and most importantly a more comprehensible definition of the profession of engineering for the purpose of being applied to all major stakeholders of the profession.

Enabling construction innovation : The role of a no-blame culture as a collaboration behavioural driver in project alliances

A no-blame culture is widely accepted as a collaboration driver yet we see surprisingly scant literature on the theoretical underpinnings for the construction and project management context. A no-blame culture in project alliances, as conducted in Australasia, promotes innovative thinking in action. Innovation is dependent upon collaboration and true collaboration is inextricably linked with behavioural drivers. Foremost of these is a culture of openness and willingness to share the pain and gain from experimentation, one that requires that collaborators be protected from the threat of being blamed and held accountable for experimental failure. The Australasian project alliance procurement form has a unique 'no-blame' behavioural contract clause that can result in the type of breakthrough thinking crucial in developing a collaborative culture where innovation can evolve through a process of trial and error. © 2014 Taylor & Francis.

MicroRNA pathways : an emerging role in identification of therapeutic strategies

For years researchers have exerted every effort to improve the influential roles of microRNA (miRNA) in regulating genes that direct mammalian cell development and function. In spite of numerous advancements, many facets of miRNA generation remain unresolved due to the perplexing regulatory networks. The biogenesis of miRNA, eminently endures as a mystery as no universal pathway defines or explicates the variegation in the rise of miRNAs. Early evidence in biogenesis ignited specific steps of being omitted or replaced that eventuate in the individual miRNAs of different mechanisms. Understanding the basic foundation concerning how miRNAs are generated and function will help with diagnostic tools and therapeutic strategies. This review encompasses the canonical and the non-canonical pathways involved in miRNA biogenesis, while elucidating how miRNAs regulate genes at the nuclear level and also the mechanism that lies behind circulating miRNAs.

The influence of mindfulness meditation on angry emotions and violent behavior on Thai technical college students

Introduction: Violence among technical college students is a significant issue in Thailand, South East Asia, and yet few interventions are available for use with this group. In this study the outcomes of a culturally appropriate intervention, mindfulness meditation (MM), on anger and violent behavior are reported. The MM intervention was delivered over three consecutive weeks to technical college students (n = 40) and the effects compared to a comparison group (n = 56) who attend classes as usual. Methods: Both the intervention and comparison group completed a series of validated self-report measures on aggressive and violent behavior perpetration and victimization on three occasions (pre-intervention, 1 month and 3 month post-intervention). Results: Program participants reported lower levels of anger expression at one month follow-up, but there were no observed group. ×. time interactions for self-reported violent behavior. Rates of victimization changed over time, with one interaction effect observed for reports of being threatened. Conclusions: MM may have the potential to improve emotional self-control, but is likely to only impact on violent behavior when this is anger mediated.

When is it OK to learn at work? The learning work of organisational practices

Purpose – The purpose of this paper is to examine the use of “learning” through what we have termed “integrated development practices”. These are common organisational practices that both enhance organisational effectiveness and contribute to organisational and employee learning.Design/methodology/approach – The paper analyses the ways in which learning and being a learner were talked about and enacted with regard to one of the integrated development practices identified in a study of four different organisations – safety practices, and how learning and being a learner regarding safety were legitimate in one of the organisations. Data are drawn from semi‐structured interviews with members of a variety of workgroups in one major division of the organisation.Findings – Interviewees' responses reflected that learning was fully embedded as an accepted part of a necessary function of the organisation. This use of a learning discourse is discussed in the light of findings from an earlier study on informal learning at work that suggested that learning and the identity of being a learner were sometimes resisted in the everyday culture of work.Originality/value – Using the theorisations of practice of Schatzki and the lifelong education framework of Delors the paper discusses the implications of these findings to examine when it is acceptable to articulate learning as part of work and be identified as a learner at work.

Airplane grows in the tummy of clouds: living through relations in the early years of life

Using a child's expression that illustrates his mental image of constituted relations of living things, the author conceptualizes relationality, an interrelated view of being, and its importance for early childhood education. The difference between relation and interaction, and the significance of inter-human relationship are discussed as significant aspects for early childhood teachers to understand as they work with children. In particular, this paper seeks to provide insights into the potential contribution of relationality towards early childhood teaching practice.

Environmental and genetic determinants of vitamin D insufficiency in 12-month-old infants

We aimed to investigate the relationship between genetic and environmental exposure and vitamin D status at age one, stratified by ethnicity. This study included 563 12-month-old infants in the HealthNuts population-based study. DNA from participants' blood samples was genotyped using Sequenom MassARRAY MALDI-TOF system on 28 single nucleotide polymorphisms (SNPs) in six genes. Using logistic regression, we examined associations between environmental exposure and SNPs in vitamin D pathway and filaggrin genes and vitamin D insufficiency (VDI). VDI, defined as serum 25-hydroxyvitamin D3(25(OH)D3) level ≤50 nmol/L, was measured using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Infants were stratified by ethnicity determined by parent's country of birth. Infants formula fed at 12 months were associated with reduced odds of VDI compared to infants with no current formula use at 12 months. This association differed by ethnicity (P;bsubesub;= 0.01). The odds ratio (OR) of VDI was 0.29 for Caucasian infants (95% CI, 0.18-0.47) and 0.04 for Asian infants (95% CI, 0.006-0.23). Maternal vitamin D supplementation during pregnancy and/or breastfeeding were associated with increased odds of infants being VDI (OR, 2.39; 95% CI, 1.11-5.18 and OR, 2.5; 95% CI, 1.20-5.24 respectively). Presence of a minor allele for any GC SNP (rs17467825, rs1155563, rs2282679, rs3755967, rs4588, rs7041) was associated with increased odds of VDI. Caucasian infants homozygous (AA) for rs4588 had an OR of 2.49 of being associated with VDI (95% CI, 1.19-5.18). In a country without routine infant vitamin D supplementation or food chain fortification, formula use is strongly associated with a reduced risk of VDI regardless of ethnicity. There was borderline significance for an association between filaggrin mutations and VDI. However, polymorphisms in vitamin D pathway related genes were associated with increased likelihood of being VDI in infancy. © 2014 Elsevier B.V. All rights reserved.

Clustering of diet, physical activity and sedentary behaviour among Australian children: cross-sectional and longitudinal associations with overweight and obesity

BACKGROUND/OBJECTIVES: Evidence suggests diet, physical activity (PA) and sedentary behaviour cluster together in children, but research supporting an association with overweight/obesity is equivocal. Furthermore, the stability of clusters over time is unknown. The aim of this study was to examine the clustering of diet, PA and sedentary behaviour in Australian children and cross-sectional and longitudinal associations with overweight/obesity. Stability of obesity-related clusters over 3-years was also examined. SUBJECTS/METHODS: Data were drawn from the baseline (T1: 2002/03) and follow-up waves (T2: 2005/06) of the Health Eating and Play Study. Parents of Australian children aged 5-6 (n=87) and 10-12 years (n=123) completed questionnaires. Children wore accelerometers and height and weight were measured. Obesity-related clusters were determined using K-medians cluster analysis. Multivariate regression models assessed cross-sectional and longitudinal associations between cluster membership, and BMI z-score and weight status. Kappa statistics assessed cluster stability over time. RESULTS: Three clusters, labelled 'most Healthy', 'Energy-dense (ED) consumers who watch TV' and 'high sedentary behaviour/low moderate-to-vigorous physical activity' were identified at baseline and at follow-up. No cross-sectional associations were found between cluster membership, and BMI z-score or weight status at baseline. Longitudinally, children in the 'ED consumers who watch TV' cluster had a higher odds of being overweight/obese at follow-up (OR=2.8; 95% CI: 1.1, 6.9; P<0.05). Tracking of cluster membership was fair to moderate in younger (K=0.24; P=0.0001) and older children (K=0.46; P<0.0001). CONCLUSIONS: This study identified an unhealthy cluster of TV viewing with ED food/drink consumption which predicted overweight/obesity in a small longitudinal sample of Australian children. Cluster stability was fair to moderate over three years and is a novel finding. Prospective research in larger samples is needed to examine how obesity-related clusters track over time and influence the development of overweight and obesity.International Journal of Obesity accepted article preview online, 24 April 2015. doi:10.1038/ijo.2015.66.

Developing teacher competencies through videos for facilitation of mathematical modelling in Singapore primary schools

Mathematical modelling tasks which are situated in real-world contexts encourage students to draw connections between school-based mathematics and the real-world, enhancing their engagement in learning. Such tasks often require varied interpretations of the real-world problem context resulting in multiple pathways of solutions. Although mathematical modelling has been introduced in the Singapore mathematics curriculum since 2007, its incorporation in schools has been limited. One reason for this could be that teachers are challenged by how best to facilitate for rich student mathematisation processes during such tasks. This chapter reports how a multi-tiered teaching experiment using design research methodology was conducted to build teachers’ capacity in designing, facilitating, and evaluating student mathematisation during mathematical modelling tasks with an intact class of Primary 5 students (aged 10-11). The use of videos was critical because grounded images helped capture the dynamics and complexity of authentic classroom interactions. This chapter highlights how video recordings of teacher-student interactions during a modelling task were harnessed during design methodology cycles, particularly during the Retrospective Analysis phase, to activate critical moments of learning for the teacher towards developing her competencies in facilitating students’ mathematisation processes.

Prevalence of cardiovascular and metabolic events in patients prescribed clozapine: a retrospective observational, clinical cohort study

BACKGROUND: The efficacy of clozapine for the treatment of schizophrenia has been demonstrated. However, a range of adverse events have been associated with its use. To date, there remains a paucity of data regarding the prevalence of clozapine-induced cardiovascular (CV) and parameters associated with the development of metabolic syndrome, alongside associated risk factors for their development. METHODS: An observational, clinical cohort study design of 355 clozapine patients who were enrolled in the Barwon Health Clozapine Program at Geelong Hospital, Victoria, Australia, between 2008-12. Medical records were accessed retrospectively. Multivariate logistic regression was used to determine associations with adverse event(s). RESULTS: Older age of commencement with clozapine was consistently associated with increased risk of CV abnormalities, with the exception of tachycardia where older age was protective (Odds Ratio [OR]: 0.97; 95% Confidence Intervals [CI]: 0.95, 0.99). Males had significantly greater odds of most metabolic disturbances with the exception of being obese (BMI: ≥30 OR: 0.45; 95% CIs: 0.24, 0.85). Older age of commencement was a significantly associated variable with High- Density Lipoprotein-cholesterol (OR: 1.03; 95% CIs: 1.01, 1.07) and fasting glucose (OR:1.04; 95% CIs: 1.02, 1.07). An increase in BMI was consistently and significantly associated with all metabolic events. CONCLUSION: Male patients who are obese at any point during treatment and older at treatment commencement may be the most vulnerable to adverse CV and metabolic events. While future studies using a matched case-control design may be required to verify these findings, we recommend that treating clinicians consider these risks when assessing patient suitability to clozapine therapy.

How active are people in metropolitan parks? An observational study of park visitation in Australia

BACKGROUND: Parks are generally an under-utilized resource in the community with great potential to enhance levels of physical activity. If parks are to attract more visitors across a broad cross-section of the population and facilitate increased physical activity, research is needed to better understand park visitor characteristics and how visitors spend their time in parks. The Recording and EValuating Activity in a Modified Park (REVAMP) study is a natural experiment monitoring a park upgrade in a low socioeconomic status (SES) neighborhood. This study described the observed baseline characteristics of park visitors (age, sex) and characteristics of visitation (weekday or weekend day, period of the day) and explored how these characteristics were associated with observed park-based physical activity in two metropolitan parks located Melbourne, Australia. METHODS: Direct observations of park visitors were conducted using a modified version of SOPARC (the System for Observing Play and Recreation in Communities) on four weekdays and four weekend days. During weekdays, observations were conducted every hour from 7:30 am-4:30 pm and on weekend days from 8:30 am-4:30 pm. This equated to a total of 1460 scans across the two parks. Chi-square tests examined bivariate associations between park-based physical activity, and socio-demographic and park visitation characteristics. Logistic regression models examined the odds of being observed engaging in moderate- to vigorous-intensity physical activity relative to lying/sitting/standing according to socio-demographic and park visitation characteristics. RESULTS: In total, 4756 park visitors were observed with the majority visiting on weekend days (87 %) and in the afternoon (41 %). Most visitors (62 %) were lying, sitting or standing, with only 29 % observed engaging in moderate-intensity and 9 % in vigorous-intensity physical activity. Park use differed by time of day, sex, age group, and neighborhood SES. Physical activity was lower for women than men (OR 0.76) and higher among visitors in the high SES area (OR 1.52). CONCLUSIONS: Parks offer substantial opportunities for people of all ages to engage in physical activity; however, this study showed that a large proportion of the park visitors observed were engaged in sedentary pursuits. Further research on how park design, amenities and programming can optimize park visitation and park-based physical activity is needed.

Hip to be hyper: the subculture of excessively local news

Local news is nothing new, but there is an unmistakable hype around its reinvention in the digital age through the hyperlocal phenomena. This article applies the lens of subculture theory to move beyond questions related to who produces hyperlocal news, how to pay for it and its democratic potential, to focus on its social and cultural values and meanings. In doing so, it engages with the normative and political economy approaches that dominate this niche of journalism studies. We argue that a cultural approach can generate much-needed critical perspectives on the significance of what we term “excessively local news” and the future of mainstream journalism in this globalized world. In the process, it challenges media scholars and practitioners who cleave to traditional hierarchies of value about what hyperlocal news is and should be, even at the risk of being unfashionable in the digital age.

New tools for understanding the local asymptotic power of panel unit root tests

Abstract Motivated by the previously documented discrepancy between actual and predicted power, the present paper provides new tools for analyzing the local asymptotic power of panel unit root tests. These tools are appropriate in general when considering panel data with a dominant autoregressive root of the form ^ρi=1+^ciN-^κT-^τ, where i=1,...,N indexes the cross-sectional units, T is the number of time periods and ^ci is a random local-to-unity parameter. A limit theory for the sample moments of such panel data is developed and is shown to involve infinite-order series expansions in the moments of ^ci, in which existing theories can be seen as mere first-order approximations. The new theory is applied to study the asymptotic local power functions of some known test statistics for a unit root. These functions can be expressed in terms of the expansions in the moments of ^ci, and include existing local power functions as special cases. Monte Carlo evidence is provided to suggest that the new results go a long way toward bridging the gap between actual and predicted power.

New trends in the making of international commercial law

This paper analyzes trends in the making of international commercial law including the impetus for generating conventions, the growth of regional conventions, and soft law.There has never been a better time to be an international commercial law scholar. After decades of being held hostage to state-centered ideas, international commercial law has finally broken through to become more solution oriented. Increasingly, nation states are becoming less important in the creation of international commercial law with the growth of regional organizations, non-state actors, and international arbitration. This is spurred on by the march of globalization and the need for international commercial law. The term "harmonization will be used as a surrogate to discuss the creation of international commercial law as it is the primary means by which international commercial law is created. This article seeks to explore two preponderant trends that have become visible in the making of international commercial law. In Part I, I shall describe the background. In Parts II and III, I will highlight the growing role of regional endeavors at harmonization, and the rise of non-binding instruments.

Changes in gait performance over several years are associated with recurrent falls status in community-dwelling older women at high risk of fracture

Background: gait analysis is a recommended geriatric assessment for falls risk and sarcopenia; however, previous research utilises measurements at a single time point only. It is presently unclear how changes in gait over several years influence risk of recurrent falls in older adults.Methods: we investigated 135 female volunteers (mean age ± SD: 76.7 ± 5.0 years; range: 70-92 years) at high risk of fracture. Gait parameters (speed, cadence, step length, step width, swing time and double support phase) were assessed using the GAITRite Electronic Walkway System at four annual clinics over ?3.7 ± 0.5 years. Participants reported incident falls monthly for 3.7 ± 1.2 years.Results: increasing gait speed (odds ratio: 0.96; 95% confidence interval 0.93, 0.99) and step length (0.87; 0.77, 0.98) from baseline to final follow-up was associated with reduced likelihood of being a recurrent faller over the study period. No significant associations were observed for baseline gait parameters (all P ≥ 0.05). At the second follow-up (2.8 ± 0.6 years), an increase in swing time (0.65; 0.43, 0.98) was associated with reduced likelihood, while an increase in double support phase (1.31; 1.04, 1.66) was associated with increased likelihood, for being a recurrent faller in the subsequent 1.3 years following this time point.Conclusion: changes in gait parameters over several years are significantly associated with the likelihood of being a recurrent faller among community-dwelling older women at high risk of fracture. Further research is required to develop gait monitoring guidelines and gait parameter decline cut points that may be utilised by clinicians to identify older adults at risk of incident falls and sarcopenia.
