Practical electromagnetic compatibility studies of a CubeSat
Authors: Sibanda Matthew , van Zyl Robert Ryk 
Published: November 2016

Purpose
Incorporating electromagnetic compatibility (EMC) in the design life of traditional satellites is entrenched in the satellite industry. However, EMC treatment of CubeSats has not been widely pursued, for various possible reasons. CubeSats are a young technology platform initially intended for students and researchers at universities to create awareness and excitement amongst them for space technology. This and other factors limited the need for stringent EMC planning. As CubeSats mature in complexity, the success of future missions will rely on incorporating proper EMC designs in their development. This paper aims to address the experimental investigation of known EMC culprits within a CubeSat’s context.

Design/methodology/approach
Electromagnetic interference suppression effectiveness of cable trays in CubeSats, as well as crosstalk in high-speed/frequency data links, is investigated, using the PC/104 connector stack. Some recommendations for improving the EMC and, therefore, enhancing satellite mission success are provided.

Findings
It was found that, if physically feasible in the CubeSat, cable trays are significant radiation suppressors. A further investigation into crosstalk between pins of the PC/104 connector stack showed that grounding a pin in between two signal pins leads to a significant reduction in the coupled signal.

Originality/value
This paper addresses EMC within the context of a CubeSat and outlines experiments done resulting in cost-effective methods of reducing interference by using already available material (such as unused signal pins available in the PC/104 connector).
Design of a heat pump water heater performance monitoring system
Authors: Tangwe Stephen Loh , Simon Michael , Meyer Edson L. 
Published: November 2016

Purpose
This paper aims to show that by using air source heat pump (ASHP) water heater in the residential sector, the energy consumption from sanitary hot water production can be reduced by more than 50 per cent. Hence, this study quantitatively and qualitatively confirms that domestic ASHP water heater is a renewable and energy efficient device for sanitary hot water production.

Design/methodology/approach
Design and building of a data acquisition system comprises a data logger, power meters, flow meters, temperature sensors, ambient and relative humidity sensor and an electronic input pulse adapter to monitor the ASHP water heater performance. All the sensors are accommodated by the U30-NRC data logger. The temperature sensors are installed on the inlet pipe containing a flow meter and the outlet pipe of the ASHP unit, the vicinity of both evaporator and expel cold air. An additional temperature sensor and a flow meter that cater for hot water drawn off measurements are incorporated into the data acquisition system (DAS).

Findings
The result from a specific monitoring split type ASHP water heater gives an average daily coefficient of performance (COP) of 2.36 and the total electrical energy of 4.15 kWh, and volume of hot water drawn off was 273 L. These results were influenced by ambient temperature and relative humidity.

Research limitations/implications
The cost involved in purchasing the entire sensors and data logger limits the number and categories of ASHP water heaters whose performance were going to be monitored. Pressure sensors were excluded in the data acquisition system.

Practical implications
The data acquisition system can easily be designed and the logger can also be easily programed. Hence, no high technical or computer skills are needed to install the DAS and to be able to read out the results.

Social implications

Hence, the data acquisition system can be installed on the entire domestic Eskom roll out air source heat pump water heaters to effectively determine the coefficient of performance and demand reductions.

Originality/value
This DAS is the first of its kind to be built in South Africa to be used to determine the performance of an ASHP water heater with high accuracy and precision. DAS is also robust.
Respect in the workplace: an evaluation of a short online intervention program
Authors: Lee Smith Shauna , Kelloway E. Kevin 
Published: November 2016

Purpose
The purpose of this paper is to evaluate the effectiveness of a short, online training program focused on respect in the workplace.

Design/methodology/approach
Using a wait-list control design the authors collected measures of workplace behaviors prior to, immediately following and six weeks following the training from a sample of long-term care employees.

Findings
The training was associated with a small increase in reported civility. Post hoc subsample analyses suggested that the training was particularly effective in increasing civility and efficacy perceptions among those respondents who had themselves reported engaging in incivility.

Practical implications
The data offer support for the effectiveness of the training but suggest that more intensive interventions may be necessary. Results also suggest that the effects of training may vary across subgroups of employees.

Originality/value
Training is one of the most frequently advocated solutions to incivility in the workplace. The findings offer support for a short, online training program.
Development and implementation of a multifaceted well-being intervention
Authors: Mills Maura J. , Fullagar Clive J. , Culbertson Satoris S. 
Published: November 2016

Purpose
The purpose of this paper is to develop and implement an intervention to increase individuals’ hedonic well-being (HWB) and/or eudaimonic well-being (EWB) via cognitive reframing and action-based behaviors.

Design/methodology/approach
Time 1 and Time 2 data were collected two weeks apart from 76 participants (comprised of city employees, extension agents, and students) in an intervention group (23) and a characteristically similar control group (53). The intervention included an in-person facilitated meeting with a series of follow-up e-mails designed to focus participants on well-being improvement strategies and provide them resources for continued well-being development.

Findings
Intervention participants evidenced a significant increase in EWB after two weeks, particularly the personal growth dimension. No significant increase resulted for HWB.

Research limitations/implications
The present intervention indicates the importance of targeting well-being at a facet level, including a focus on multidimensional EWB. The intervention also serves to guide the informed development of future well-being programs.

Practical implications
These findings have important implications for organizations in light of increased employee desire for personal and professional growth opportunities supported by their employer. Group interventions such as the one reported herein are an important way for organizations to develop and invest in employees.

Originality/value
This paper traces the development of prior well-being interventions, evaluating their successes and failures and using those to guide the informed development of the present intervention. By utilizing both in-person and follow-up components, and incorporating both hedonic and multidimensional eudaimonic components, the proposed intervention serves as an important step toward a feasible organizational intervention that can benefit many.
Assessment committees: good practices from ARL libraries
Authors: Brannen Michelle H. , Cunningham Sojourna J. , Mays Regina 
Published: November 2016

Purpose
Assessment activities in academic libraries continue to grow as libraries explore assessment endeavors. Ranging from basic stats gathering and reporting to surveys, focus groups, and usability studies and beyond. Many practitioners are finding it necessary to create new processes and programs, with little guidance. The purpose of this paper is to paint a broad picture of assessment activities in Association of Research Libraries (ARL) university libraries with the goal of creating a resource for libraries developing or improving their assessment programs.

Design/methodology/approach
A survey was developed that asked questions about assessment personnel, activities, mission, and website. A total of 113 surveys were sent to academic library members of ARL. Survey results were analyzed to compile a list of recommended good practices for assessment and working with assessment committees in academic libraries.

Findings
The investigators had a response rate of 43 percent. The open-ended nature of the survey questions allowed for the respondents to specifically narrow down the problems and opportunities inherent in library assessment committees.

Originality/value
This study takes the temperature of the current state of assessment programs in ARL libraries, demonstrating the growth of assessment programs. It begins to document the practices of these libraries, particularly in regards to the sometimes informal and hard to track use of committees and other in-house collaborations, as a first step toward developing best practices for the field. The results illuminate productive areas for further study, including investigating how to measure a culture of assessment and maximizing impact of assessment information presented on assessment websites.
Shaping solutions from learnings in PAIs: a blueprint
Authors: Dosanjh Nawtej , Jha Pushkar P. 
Published: November 2016

Purpose
The paper outlines a portal that facilitates learning through sharing of experiences. This flow is between experience sharers and solution seekers in the domain of poverty alleviation interventions (PAIs). Practitioners working on PAIs are often confined to searching from within “lessons learned” repositories and also from within limited disparate networks configured by aid agencies and consultancies. They do not, as of yet, have access to a comprehensive portal that explores the pool of knowledge carriers and also evaluates their efficacy in contributing to customised solutions.

Design/methodology/approach
The paper critiques the sufficiency of existing processes for feedback generation and its use in PAIs. In relating to varying contexts of PAIs and experiences that exist from practice, it presents a template of an internet enabled interface to support experience sharing. The authors then illustrate how the portal can deliver to specific issues and problems in different PAI contexts.

Findings
The SOLVER portal and its process map aim to create an interfacing environment between sharers and seekers for shaping customized solutions from past experiences.

Originality/value
Improving the performance of PAIs is crucial for societal goals of equitable living and access to opportunity spaces. PAI practitioners are aware of the wealth of past experiences but then struggle to find a coherent and approachable portal that can churn these in response to their specific and contextual needs.
Plant–phytopathogen interactions: bacterial responses to environmental and plant stimuli
Authors: Leonard Simon , Hommais Florence , Nasser William , Reverchon Sylvie 
Published: November 2016

SummaryPlant pathogenic bacteria attack numerous agricultural crops, causing devastating effects on plant productivity and yield. They survive in diverse environments, both in plants, as pathogens, and also outside their hosts as saprophytes. Hence, they are confronted with numerous changing environmental parameters. During infection, plant pathogens have to deal with stressful conditions, such as acidic, oxidative and osmotic stresses; anaerobiosis; plant defenses; and contact with antimicrobial compounds. These adverse conditions can reduce bacterial survival and compromise disease initiation and propagation. Successful bacterial plant pathogens must detect potential hosts and also coordinate their possibly conflicting programs for survival and virulence. Consequently, these bacteria have a strong and finely tuned capacity for sensing and responding to environmental and plant stimuli. This review summarizes our current knowledge of the signals and genetic circuits that affect survival and virulence factor expression in three important and well‐studied plant pathogenic bacteria with wide host ranges and the capacity for long‐term environmental survival. These are: Ralstonia solanacerarum, a vascular pathogen that causes wilt disease; Agrobacterium tumefaciens, a biotrophic tumorigenic pathogen responsible for crown gall disease and Dickeya, a brute force apoplastic pathogen responsible for soft‐rot disease.
Enclisis/Proclisis Alternations in Romance: Allomorphies and (Re)Ordering
Authors: Manzini M. Rita , Savoia Leonardo M. 
Published: November 2016

AbstractRomance clitic pronouns appear to the left of the verb in I and to the right of the verb in C. This alternation correlates with: (a) allomorphy, specificallyl‐vs. zero; (b) stress shifts; and (c) reordering of the clitic string. The alternations in (a)–(c) are also observed between non‐negative and negative contexts. The key points of our analysis are: (i) thel‐ segment is associated with definite content; (ii) interpretively, pronouns scope out of modal/non‐veridical operators; (iii) syntactically, the exponent for modality/non‐veridicality may have the pronoun in its domain; (iv) externalization of thel‐segment is found when semantic scope (ii) and syntactic configuration (iii) are mismatched. Therefore allomorphies (including stress), far from being morphophonological quirks, contribute to the externalization of syntactico‐semantic notions of non‐veridicality. In dealing with clitic (re)ordering we propose a model based on the dissociation between Merge and linear order. Phrasal constituents are ordered to the right of the verb in Romance; clitics mirror them in that they are ordered to the left, while keeping the Merge relations constant.
The Role of Non‐Use Values in Dairy Farmers’ Willingness to Accept a Farm Animal Welfare Programme
Authors: Schreiner Julia A. , Hess Sebastian 
Published: November 2016

AbstractChoice experiments about a hypothetical farm animal welfare (FAW) programme were presented to a sample of randomly selected German dairy farmers. Based on the theory of social interactions, it was hypothesised that the probability of participating in the programme would increase with (i) the ease of implementing programme attributes on the farm, (ii) perceived use values such as increased milk yield, and (iii) stated levels of non‐use existence values derived from improved animal welfare conditions and extrinsically motivated non‐use values from enhanced prestige among relevant peer groups. It was found that non‐use existence values were negatively related to programme acceptance because relatively high personal standards may not be in line with the programme design and may make the programme seem unnecessary. In addition, the intention of enhancing public acceptance of dairy farming appeared to have an influence on some farmers’ willingness to accept the programme, which can be explained by the relevance of social interactions among peers in the context of farmers’ provision of FAW.
Under Our Nose: The Use of GIS Technology and Case Notes to Focus Search Efforts
Authors: Bunch Ann W. , Kim Moonsun , Brunelli Ronald 
Published: November 2016

AbstractMissing person searches can entail much time, effort, and resources. With scientific data and techniques increasingly available to law enforcement and investigations units, can these tools be used to predict likely areas where persons or remains may be discovered, especially in cases where little to no information about the disappearance is available? A retrospective study of seventy‐three (73) cases was conducted in Onondaga County, New York, U.S.A., in order to explore this question. Quantitative (geospatial) and qualitative (investigator notes) data were utilized to determine whether patterns exist that may assist in investigations of recent and “cold” missing person cases. Results showed a majority of cases with relative proximity (<5 miles) between victim last seen (VLS) and body recovered (BR) locations. Furthermore, investigators’ notes demonstrated repeated descriptors reflecting natural or cultural features associated with hidden, clandestine provenance (e.g., near bodies of water, wooded areas). With future external validation of this study, consistent priority areas may be identified as foci of searches; these priority areas ideally should be thoroughly checked/cleared before the search zone is expanded.
Comparing Methods to Assess Intraobserver Measurement Error of 3D Craniofacial Landmarks Using Geometric Morphometrics Through a Digitizer Arm
Authors: Menéndez Lumila Paula 
Published: November 2016

AbstractIntraobserver error (INTRA‐OE) is the difference between repeated measurements of the same variable made by the same observer. The objective of this work was to evaluate INTRA‐OE from 3D landmarks registered with a Microscribe, in different datasets: (A) the 3D coordinates, (B) linear measurements calculated from A, and (C) the six‐first principal component axes. INTRA‐OE was analyzed by digitizing 42 landmarks from 23 skulls in three events two weeks apart from each other. Systematic error was tested through repeated measures ANOVA (ANOVA‐RM), while random error through intraclass correlation coefficient. Results showed that the largest differences between the three observations were found in the first dataset. Some anatomical points like nasion, ectoconchion, temporosphenoparietal, asterion, and temporomandibular presented the highest INTRA‐OE. In the second dataset, local distances had higher INTRA‐OE than global distances while the third dataset showed the lowest INTRA‐OE.
Geo‐spatial analyses in education research: the critical challenge and methodological possibilities
Authors: Lubienski Christopher , Lee Jin 
Published: November 2016

AbstractThe usefulness of spatial perspectives in education research is well known, particularly in fields such as school choice that are operationalised in multiple institutional, demographic, and local geographies. But the modes of spatial inquiry, even as they can potentially lend themselves to integrated research strategies, tend to be fragmented and isolated, failing to take into account multiple dimensions of contextual factors. Our purpose is to provide critical deliberations on geo‐spatial methods in school choice research and suggest an integrative approach to enhance research on school choice from a geographic perspective. This paper first demonstrates the linkage of spatial approaches to school choice, and then surveys geo‐spatial research as typically leveraged on this issue. We argue that there are inherent limitations to the typical conceptions of space in geo‐spatial analyses and discuss two of the major challenges to these conceptions as provided by critical theorists and geographers. But we also point out that these challenges suggest alternatives that themselves have serious shortcomings. The concluding discussion sets out some of the possibilities of a more integrated approach to spatial inquiry in education research, and school choice more specifically.
Owning the tooth: exploring the ethical and legal issues relating to the use of extracted human teeth in dental education in Australia
Authors: Holden ACL , Dracopoulos SA 
Published: November 2016

AbstractExtracted human teeth have been used to practice operative techniques for a very long time. As a natural surrogate for a live tooth in vivo, their use has traditionally been very important for the development of skills in trainee dentists, as well as their qualified colleagues who wish to practise existing or new skills. As synthetic alternatives develop greater authenticity, alongside a society in which many retain their natural dentition well into old age, the current paradigm relating to how extracted teeth in dental education are used needs to be revisited. An ethical and legal dilemma that must be addressed within dental education relates to where and how teeth may be sourced. This article will seek to question whether there is a legal or ethical requirement to gain consent for the use of extracted teeth from patients, as well as exploring the status of whether extracted dental tissue can be considered to be the property of either patient or surgeon. Whilst synthetic alternatives are being utilized more frequently in education, it is unlikely that they will completely replace extracted natural teeth in the immediate future. It is therefore imperative that their use complies with legal doctrine and contemporary ethical thought.
Antenatal ultrasound features in fetuses with gastroschisis and its prediction in neonatal outcome
Authors: Robertson Jessica A. , Kimble Roy M. , Stockton Kellie , Sekar Renuka 
Published: November 2016

BackgroundGastroschisis is the most common major congenital anomaly managed by paediatric surgeons. The significance of certain associated antenatal ultrasound features in determining fetal outcome is under discussion.AimThe study aims to define if associated antenatal ultrasound features of gastroschisis are useful prognostic markers for fetal outcome. By establishing the significance of features, including extra‐ and intra‐abdominal bowel dilatation, stomach herniation, stomach dilatation, bowel matting, growth restriction, abnormal umbilical artery (UA) Doppler ultrasounds, and abnormal amniotic fluid volume, it is hoped clinicians will have enhanced ability to counsel parents about the likely outcomes for their infant.Materials and MethodsRetrospective analysis of ultrasound images, reports and medical records of 101 pregnancies affected by fetal gastroschisis managed by the Royal Brisbane and Women's Hospital Maternal and Fetal Medicine Department over a 13 and a half year period was performed. The presence of ultrasound features during antenatal surveillance corresponded to fetal outcome measures, including the diagnosis of postnatal complex gastroschisis, the number of operations required, length of parenteral feeding and length of stay in neonatal intensive care.ResultsThe only statistically significant predictor of complex cases of gastroschisis was extra‐abdominal bowel dilatation. Although a statistically significant feature, approximately three‐quarters (44/59) of all infants with gastroschisis with associated extra‐abdominal bowel dilatation had simple gastroschisis.ConclusionsExtra‐abdominal bowel dilatation is a statistically significant marker of complex gastroschisis and associated morbidity. Its presence in infants who had uncomplicated outcomes, suggests that clinically, its usefulness in antenatal counselling is still debatable.
