Empirical studies of pair programming for CS/SE teaching in higher education: a systematic literature review

The objective of this paper is to present the current evidence relative to the effectiveness of pair programming (PP) as a pedagogical tool in higher education CS/SE courses. We performed a systematic literature review (SLR) of empirical studies that investigated factors affecting the effectiveness of PP for CS/SE students and studies that measured the effectiveness of PP for CS/SE students. Seventy-four papers were used in our synthesis of evidence, and 14 compatibility factors that can potentially affect PP's effectiveness as a pedagogical tool were identified. Results showed that students' skill level was the factor that affected PP's effectiveness the most. The most common measure used to gauge PP's effectiveness was time spent on programming. In addition, students' satisfaction when using PP was overall higher than when working solo. Our meta-analyses showed that PP was effective in improving students' grades on assignments. Finally, in the studies that used quality as a measure of effectiveness, the number of test cases succeeded, academic performance, and expert opinion were the quality measures mostly applied. The results of this SLR show two clear gaps in this research field: 1) a lack of studies focusing on pair compatibility factors aimed at making PP an effective pedagogical tool and 2) a lack of studies investigating PP for software design/modeling tasks in conjunction with programming tasks.

The effect of software engineers' personality traits on team climate and performance: a systematic literature review

Context Over the past 50 years numerous studies have investigated the possible effect that software engineers' personalities may have upon their individual tasks and teamwork. These have led to an improved understanding of that relationship; however, the analysis of personality traits and their impact on the software development process is still an area under investigation and debate. Further, other than personality traits, "team climate" is also another factor that has also been investigated given its relationship with software teams' performance. Objective The aim of this paper is to investigate how software professionals' personality is associated with team climate and team performance. Method In this paper we detail a Systematic Literature Review (SLR) of the effect of software engineers' personality traits and team climate on software team performance. Results Our main findings include 35 primary studies that have addressed the relationship between personality and team performance without considering team climate. The findings showed that team climate comprises a wide range of factors that fall within the fields of management and behavioral sciences. Most of the studies used undergraduate students as subjects and as surrogates of software professionals. Conclusions The findings from this SLR would be beneficial for understanding the personality assessment of software development team members by revealing the traits of personality taxonomy, along with the measurement of the software development team working environment. These measurements would be useful in examining the success and failure possibilities of software projects in development processes. General terms Human factors, performance.

A systematic review of body dissatisfaction and sociocultural messages related to the body among preschool children.

This systematic review examines body dissatisfaction and the influence of sociocultural messages related to body image among preschool children. The review was conducted according to the PRISMA guidelines and 16 studies were included in the final analysis. Findings suggest that children under the age of 6 years old experience body dissatisfaction, however, the proportion of children who are dissatisfied varied from around 20% to 70%, depending on the method of assessment. The literature was divided on whether preschool aged girls experience more body dissatisfaction than boys. Parental influence appears to be an important factor in the development of preschool children's body dissatisfaction and attitudes. However, more research is needed to understand the influences of children's peers and the media. The need for more sensitive measures of body dissatisfaction and prevention programs for preschool children is discussed.

A multiple case history and systematic review of adoption, diffusion, implementation and impact of provincial daily physical activity policies in Canadian schools

BACKGROUND : Few children meet physical activity (PA) recommendations, and are therefore at increased risk for overweight/obesity and adverse health outcomes. To increase children's opportunities for PA, several Canadian provinces have adopted school-based daily PA (DPA) policies. It is not clear why some jurisdictions have adopted DPA policies, and others have not, nor whether these policies have been implemented and have achieved their intended outcomes. The purpose of this study was to understand the processes underlying adoption and diffusion of Canadian DPA policies, and to review evidence regarding their implementation and impact.

METHODS: We adopted a multiple case history methodology in which we traced the chronological trajectory of DPA policies among Canadian provinces by compiling timelines detailing key historical events that preceded policy adoption. Publicly available documents posted on the internet were reviewed to characterize adopter innovativeness, describe the content of their DPA policies, and explore the context surrounding policy adoption. Diffusion of Innovations theory provided a conceptual framework for the analyses. A systematic literature search identified studies that had investigated adoption, diffusion, implementation or impact of Canadian DPA policies.

RESULTS: Five of Canada's 13 provinces and territories (38.5%) have DPA policies. Although the underlying objectives of the policies are similar, there are clear differences among them and in their various policy trajectories. Adoption and diffusion of DPA policies were structured by the characteristics and capacities of adopters, the nature of their policies, and contextual factors. Limited data suggests implementation of DPA policies was moderate but inconsistent and that Canadian DPA policies have had little to no impact on school-aged children's PA levels or BMI.

CONCLUSIONS: This study detailed the history and current status of Canadian DPA policies, highlighting the conditional nature of policy adoption and diffusion, and describing policy and adopter characteristics and political contexts that shaped policy trajectories. An understanding of the conditions associated with successful policy adoption and diffusion can help identify receptive contexts in which to pioneer novel legislative initiatives to increase PA among children. By reviewing evidence regarding policy implementation and impact, this study can also inform amendments to existing, and development of future PA policies.

A systematic mapping study of mobile application testing techniques

The importance of mobile application specific testing techniques and methods has been attracting much attention of software engineers over the past few years. This is due to the fact that mobile applications are different than traditional web and desktop applications, and more and more they are moving to being used in critical domains. Mobile applications require a different approach to application quality and dependability and require an effective testing approach to build high quality and more reliable software. We performed a systematic mapping study to categorize and to structure the research evidence that has been published in the area of mobile application testing techniques and challenges that they have reported. Seventy nine (79) empirical studies are mapped to a classification schema. Several research gaps are identified and specific key testing issues for practitioners are identified: there is a need for eliciting testing requirements early during development process; the need to conduct research in real-world development environments; specific testing techniques targeting application life-cycle conformance and mobile services testing; and comparative studies for security and usability testing.

Parent-related mechanisms underlying the social gradient of childhood overweight and obesity: a systematic review

BACKGROUND: Low socio-economic status (SES) is a significant risk factor for childhood overweight and obesity (COWOB) in high-income countries. Parents to young children buffer and accentuate social and cultural influences, and are central to the development of this disease. An understanding of the parent-related mechanisms that underlie the SES-COWOB relationship is needed to improve the efficacy of prevention and intervention efforts. OBJECTIVE: A systematic review of relevant literature was conducted to investigate the mechanisms by which levels of SES (low, middle and high) are associated to COWOB, by exploring mediation and interaction effects. METHOD: Six electronic databases were searched yielding 5155 initial records, once duplicates were removed. Studies were included if they investigated COWOB, SES, parent-related factors and the multivariate relationship between these factors. Thirty studies were included. Factors found to be mediating the SES-COWOB relationship or interacting with SES to influence COWOB were categorized according to an ecological systems framework, at child, parent, household and social system level factors. RESULTS: High parent body mass index, ethnicity, child-care attendance, high TV time (mother and child), breastfeeding (early weaning), food intake behaviours and birthweight potentially mediate the relationship between SES and COWOB. Different risk factors for COWOB in different SES groups were found. For low SES families, parental obesity and maternal depressive symptoms were strong risk factors for COWOB, whereas long maternal working hours and a permissive parenting style were risk factors for higher SES families. None of the studies investigated parental psychological attributes such as attitudes, beliefs, self-esteem and so on as potential mechanisms/risk factors. CONCLUSIONS: Families from different SES groups have different risk and protective factors for COWOB. Prevention and intervention efforts may have improved efficacy if they are tailored to address specific risk factors within SES.

A systematic investigation into a novel method for preparing carbon fibre–carbon nanotube hybrid structures

By electrospraying solvent dispersed carbon nanotubes (CNTs) with a binder onto carbon fibre (CF), hybrid structures, with an end aim to improve interfacial bonding in composites, were formed. The electrospray parameters controlling the modification of the CNT morphologies were studied. High-speed camera observations found applied voltage was critical for determining spray mode development. Electric field simulations revealed a concentrated electric field region around each fibre. Both voltage and distance played an important role in determining the CNT morphology by mediating anchoring strength and electric field force. The forming mechanism investigation of different surface morphologies suggested that binder with appropriate wetness gives freedom to the CNTs, allowing them to orientate radially from the CF surface. Linear density (LD) measurements and thermogravimetric analysis revealed that a 10 min coating increased the LD of a single CF filament by up to 31.7% while a 1 h treatment increased fibre bundle mass by 1%.

Validity of short food questionnaire items to measure intake in children and adolescents: a systematic review

BACKGROUND: Short food questions are appealing to measure dietary intakes. METHODS: A review of studies published between 2004 and 2016 was undertaken and these were included in the present study if they reported on a question or short item questionnaire (≤50 items, data presented as ≤30 food groups) measuring food intake or food-related habits, in children (aged 6 months to 18 years), and reported question validity or reliability. Thirty studies met the inclusion criteria. RESULTS: Most questions assessed foods or food groups (n = 29), with the most commonly assessed being fruit (n = 22) or vegetable intake (n = 23), dairy foods and discretionary foods (n = 20 studies each). Four studies assessed food habits, with the most common being breakfast and meal frequency (n = 4 studies). Twenty studies assessed reliability, and 25 studies determined accuracy and were most commonly compared against food records. Evaluation of question performance relied on statistical tests such as correlation. CONCLUSIONS: The present study has identified valid and reliable questions for the range of key food groups of interest to public health nutrition. Questions were more likely to be reliable than accurate, and relatively few questions were both reliable and accurate. Gaps in repeatable and valid short food questions have been identified that will provide direction for future tool development.

Understanding the bereavement care roles of nurses within acute care: a systematic review

AIM AND OBJECTIVES: To investigate nurses' roles and responsibilities in providing bereavement care during the care of dying patients within acute care hospitals.

BACKGROUND: Bereavement within acute care hospitals is often sudden, unexpected and managed by nurses who may have limited access to experts. Nurses' roles and experience in the provision of bereavement care can have a significant influence on the subsequent bereavement process for families. Identifying the roles and responsibilities nurses have in bereavement care will enhance bereavement supports within acute care environments.

DESIGN: Methods: A mixed-methods systematic review was conducted utilising the databases Cumulative Index Nursing and Allied Health Literature (CINAHL Plus), Embase, Ovid MEDLINE, PsychINFO, CareSearch and Google Scholar. Included studies published between 2006 to 2015, identified nurse participants, and the studies were conducted in acute care hospitals. Seven studies met the inclusion criteria and the research results were extracted and subjected to thematic synthesis.

RESULTS: Nurses' role in bereavement care included patient-centred care, family-centred care, advocacy and professional development. Concerns about bereavement roles included competing clinical workload demands, limitations of physical environments in acute care hospitals and, the need for further education in bereavement care.

CONCLUSIONS: Further research is needed to enable more detailed clarification of the roles nurse undertake in bereavement care in acute care hospitals. There is also a need to evaluate the effectiveness of these nursing roles and how these provisions impact on the bereavement process of patients and families. 

A systematic review and meta-analysis on the longitudinal relationship between eating pathology and depression.

OBJECTIVE: Undertake a meta-analysis to provide a quantitative synthesis of longitudinal studies that assessed the direction of effects between eating pathology and depression. A second aim was to use meta-regression to account for heterogeneity in terms of study-level effect modifiers. METHOD: A systematic review was conducted on 42 studies that assessed the longitudinal relationship between eating pathology and depression. Of these 42 studies, multilevel random-effects meta-analyses were conducted on 30 eligible studies. RESULTS: Meta-analysis results showed that eating pathology was a risk factor for depression (rm  = 0.13) and that depression was a risk factor for eating pathology (rm  = 0.16). Meta-regression analyses showed that these effects were significantly stronger for studies that operationalized eating pathology as an eating disorder diagnosis versus eating pathology symptoms, and for studies that operationalized the respective outcome measure as a categorical variable (e.g., a diagnosis of a disorder or where symptoms were "present"/"absent") versus a continuous measure. Results also showed that in relation to eating pathology type, the effect of an eating disorder diagnosis and bulimic symptoms on depression was significantly stronger for younger participants. DISCUSSION: Eating pathology and depression are concurrent risk factors for each other, suggesting that future research would benefit from identifying factors that are etiological to the development of both constructs. RESUMEN OBJETIVO: Llevar a cabo un meta-análisis para proporcionar una síntesis cuantitativa de los estudios longitudinales que evaluaron la dirección de los efectos entre la alimentación patológica y la depresión. Un segundo objetivo fue utilizar la meta-regresión para dar cuenta de la heterogeneidad en términos de modificadores del efecto a nivel de estudio. MÉTODO: Una revisión sistemática se llevó a cabo en 42 estudios que evaluaron la relación longitudinal entre la alimentación patológica y la depresión. De estos 42 estudios, se realizaron meta-análisis de multinivel de efectos aleatorios en 30 estudios elegibles. RESULTADOS: Los resultados del meta-análisis mostraron que la alimentación patológica era un factor de riesgo para depresión (rm=0.13) y que la depresión era un factor de riesgo para la alimentación patológica (rm=0.16). Los análisis de meta-regresión mostraron que estos efectos eran significativamente más fuertes para estudios que operacionalizaban la alimentación patológica como un diagnóstico de trastorno de la conducta alimentaria versus síntomas de alimentación patológica, y para los estudios que operacionalizaban la medida respectiva de resultado como una variable categórica (e.g., un diagnóstico de trastorno o cuando los síntomas estaban "presentes"/"ausentes") versus una medida continua. Los resultados mostraron que en relación al tipo de alimentación patológica, el efecto de un diagnóstico de trastorno de la conducta alimentaria y síntomas bulímicos en la depresión era significativamente más fuerte para participantes más jóvenes. DISCUSIÓN: La alimentación patológica y la depresión son factores de riesgo concurrentes uno para el otro, lo que sugiere que la investigación futura se beneficiaría de identificar factores que son etiológicos al desarrollo de ambos constructos. © 2015 Wiley Periodicals, Inc.

Early childhood education and care educators supporting parent-child relationships: a systematic literature review

Building strong relationships between children and parents is vital for children’s social and emotional development. A majority of children attend early childhood education and care (ECEC) settings where they experience a range of relationships (educator–child, educator– parent, parent–child). Educators build relationships with children and parents, yet their influence on parent–child relationships is not well understood. Therefore, an evaluation of interventions/programs designed to promote parent–child relationships in ECEC settings (long day care, occasional care and preschool) and a range of settings (play groups, community groups and health centers) was conducted. The search revealed 21 peer-reviewed studies and seven interventions: two conducted in ECEC settings and five in a range of parent–child support settings. All studies reported intervention efficacy, yet none examined educators’ influence on parent–child relationships. Investigation into current educator practices is recommended to ensure educators are supported to promote and nurture parent– child relationships, consequently strengthening children’s social and emotional development.

Developing physical and physiological employment standards: translation of job analysis findings to assessments and performance standards - a systematic review

Physical employment standards (PES) are developed with the aim of ensuring that an employee's physical and physiological capacities are commensurate with the demands of their occupation. While previous commentaries and narrative reviews have provided frameworks for the development of PES, this is the first systematic review of the methods used to translate job analysis findings to PES tests and performance standards for physically demanding occupations. A search of PubMed and Google Scholar was conducted for research articles published in English up to and including March 2015. Two authors independently reviewed and extracted data.

The search yielded 87 potentially eligible papers, including 60 peer reviewed journal articles and 17 technical reports. 57 papers were excluded leading to a final data set of 31 papers, representing 22 studies. Job analysis was most commonly conducted through subjective determination of job tasks followed by objective quantification and validation. Determination of criterion tasks was evenly distributedthrough subjective and objective methods with criterion tasks being defined most commonly as most demanding, critical and/or frequent. Generic predictive and task-related predictive tests were more commonly observed in isolation or in combination when compared to task simulation tests. Performance standards were more commonly criterion-referenced than norm-referenced with a variety of statistical methods utilised. This review provides recommendations for researchers when developing physical employment standards for a variety of occupations.
