Household adoption of rainwater harvesting (RH) systems recently boomed in Australian urban centres. As a sustainable supplement to the mains supply, water authorities regarded RH as a demand management device. Yet what actually motivated household RH adoption was not well understood. Burawoy's ‘extended case method’ was used to link grounded enquiry with 13 core theoretical concepts drawn from an original synthesis of ecological modernisation and diffusion of innovation theories. This framework means the household experience extends ideas drawn from existing theory to explore issues that influence the household RH adoption decision. The framework was interrogated with data drawn from a self-report survey of 560 homes. It accommodated 100% of the RH adoption issues identified by households. Further staged quantitative and qualitative analyses particularized these core concepts out to 36 discrete ‘subfactors’ which were used in discriminant function analyses. 17 subfactors contribute to a discriminant function grouping 89.2% of households to the correct ‘adopter’ or ‘nonadopter’ category (p < 0.000). The model provides a transparent, robust, empirical basis for understanding the issues that influence household RH adoption and can be applied to social marketing aimed at facilitating further penetration of household RH.

Player Experience

Measuring theoretical concepts, so-called constructs, is a central challenge of Player Experience research. Building on recent work in HCI and psychology, we conducted a systematic literature review to study the transparency of measurement reporting. We accessed the ACM Digital Library to analyze all 48 full papers published at CHI PLAY 2020, of those, 24 papers used self-report measurements and were included in the full review. We assessed specifically, whether researchers reported What, How and Why they measured. We found that researchers matched their measures to the construct under study and that administrative details, such as number of points on a Likert-type scale, were frequently reported. However, definitions of the constructs to be measured and justifications for selecting a particular scale were sparse. Lack of transparency in these areas threaten the validity of singular studies, but further compromise the building of theories and accumulation of research knowledge in meta-analytic work. This work is limited to only assessing the current transparency of measurement reporting at CHI PLAY 2020, however we argue this constitutes a fair foundation to asses potential pitfalls. To address these pitfalls, we propose a prescriptive model of a measurement selection process, which aids researchers to systematically define their constructs, specify operationalizations, and justify why these measures were chosen. Future research employing this model should contribute to more transparency in measurement reporting. The research was funded through internal resources.

ObjectivePhysicians' attitudes and adoption behavior toward the delivery of prenatal tests take vital significance for its influence on their professional practice and patient acceptance. This study aimed to identify how physicians have perceived the diffusion of non-invasive prenatal testing (NIPT) in China.MethodsA cross-sectional study was conducted from July 2016 to October 2016 in Shanghai, and Fujian and Sichuan Provinces in China. Physicians working on prenatal screening completed a self-report questionnaire. Following Roger's diffusion of innovation model, multivariable logistic regressions were performed separately for the following key elements of the theory which influence diffusion: physician-perceived attributes of NIPT, communication channels, the nature of the social system, the extent of change agent (who introduces innovations into a society), promotion efforts, and physicians' benefits from adopting NIPT.ResultsMost specialists had a positive attitude (53.2 percent) toward NIPT, whereas 58.9 percent of physicians had already adopted NIPT in their clinical practice. Physician adoption of NIPT was positively associated with the strength of HTA evidence (p = .03), perceived communication frequency with colleagues (p = .04), adoption by other physicians (p = .07), hospital competition (p = .06), hospital teaching status (p = .02), perceived for-profit genetic testing company's promotion (p < .001), and perceived clinical practice skill improvement (p = .02). However, the adoption behavior toward NIPT may be negatively associated with physician-perceived ethical concerns of NIPT (p = .06).ConclusionObstetricians and gynecologists’ positive perceptions facilitate the adoption of NIPT. Combined with cost-effectiveness analysis of prenatal screening methods, health policy makers can promote the adoption of appropriate, cost-effective prenatal screening in pregnant women.

Performance Enhancing

Doping, or performance enhancing drug use, has long been a social and health problem among athletes. Despite the issues associated with doping and the illegality of using these drugs, little criminological research has examined why athletes engage in this deviant behavior. The present study seeks to do so by applying key theoretical concepts derived from, and testing the predictive efficiency of, situational action theory on professional athletes’ past, current, and future performance enhancing drug use. We employ self-report data from a random sample of 680 professional athletes from Rasht, Iran. Ordinary least squares regression is used to analyze these data. Findings suggest that crime propensity and criminogenic exposure increase athletes’ doping behavior. In addition, we find the interaction term between crime propensity and criminogenic exposure influences performance enhancing drug use among professional athletes, while increasing the model’s predictive power. Finally, in contrast to situational action theory, we find that known correlates of deviance (education, age, and gender) still influence athletes’ doping behavior even when key theoretical variables are included in the model.

Purpose – The purpose of this paper is to develop a research model that links Radio Frequency Identification (RFID) adoption issues with established technology adoption stages suggested by Rogers theory of diffusion of innovation (DOI). The research model proposed in this study suggests that RFID adoption in retail industry progresses in different stages. Design/methodology/approach – A mixed methodological perspective is used in this research. Key research issues were identified from a systematic content analysis of trade and academic articles in the first phase. Findings – Data collected from Delphi study is used to test the propositions. It confirms key research issues associated with different adoption stages. Finally, it also confirms that the stages (knowledge, persuasion, design and decision, and implementation) influence RFID adoption decision. Research limitations/implications – The propositions that are developed in the model can be used in future studies for further development. More relevant items should be added to measure each variable. It can also allow future researchers and practitioners to take a more comprehensive approach to look at RFID adoption process as a whole and thus focus on relevant issues across all adoption stages. Practical implications – The research model can provide insights to practitioner to make more informed RFID adoption decisions. Originality/value – Rogers stage model is very important for technology diffusion studies but is not explored much. There is limited research on understanding the overall RFID adoption process. This study is an attempt to bridge that gap and draw attention toward future research in that direction. The research model that is developed links RFID research with existing research in the area of DOI.

Background Creating greater stability in the teacher labor force and improving teacher quality is an important education policy priority in the United States. While there is a robust literature on the external, environmental reasons teachers stay in or leave the occupation, little is known about the role internal, person-level factors play in teacher retention, especially among academically elite teachers. Focus of Study This study explores the role of personality, holistically defined, in teacher commitment. Participants The sample for this study consists of 107 graduates of a single teacher preparation program. They are classified as “academically elite,” as this preparation program is very selective and demands high GRE scores. Research Design Discriminant function and regression analyses are used to test which of a rich set of personality measures, both traditional self-report measures and coded narrative accounts of life and career high points, predict long-term commitment to teaching in this sample. Results Discriminant function analysis exploring differences between very long-term committers (15+ years) and short-term committers (7- years) suggests that long-term committers are distinguished by a “special kind of ambition”: they set goals that are both more difficult and more prosocial than their counterparts with a shorter commitment to the occupation, and in personal narratives they more often show “enlightened self-interest,” a combination of self-interest/self-promotion with concern for and connection to others. In addition, regression analyses show that these personality variables significantly predict retention in the sample as a whole, even when controlling for school advantage. Conclusions These results provide evidence that personality does play an important role in teachers’ occupational commitment, call into question pervasive stereotypes in the United States of teachers as unambitious, and suggest ways academically elite teachers might be able to shift the ways they think about their work in order to sustain themselves in the occupation.

The City

The effects of climate change on rainfall in the Mediterranean region are manifested in an overall decreasing trend, and greater irregularity in annual volumes and the city of Alicante is no exception. In addition, there has also been a spread of the urbanised area, which has led to an increase in the flood risk in urban areas (due to a greater runoff and the occupation of flood hazard areas) and drought events due to an increase in the water demand. In light of these new scenarios, the Mediterranean cities should design adaptation systems based on rainwater harvesting within the framework of a circular economy. This study analyses the integration of rainwater in flood and water demand management in the city of Alicante (Southern Spain). In recent years, this city has developed infrastructures in order to use these resources. To do this, different databases have been analysed (rainfall and volume of water collected in the green infrastructure systems). The results reveal that stormwater has become highly important in urban water management in Alicante as the city is now using a resource that previously went to waste and created problems (flooding and pollution). By way of conclusion, it is worth mentioning that the incorporation of rainwater for urban use in Alicante has reduced the pressure on traditional resources in satisfying water demand and has also acted as a measure for adapting to climate change.

The expansion of online social networking sites and the relative accessibility to personal information provided by these sites has raised concerns about the risks for a variety of negative experiences, including cyberstalking. The present study investigated whether the theoretical concepts of Routine Activities Theory (RAT) could account for patterns of cyberstalking victimization among social networking site users. The study employed a self-report survey design using a convenience sample of 321 female undergraduate students. RAT was operationalized in the cyber context by measuring the level of online disclosure, frequency of internet use (online exposure) and general proclivity for risk-taking behaviours among participants. Personal experiences of cyberstalking were also assessed. Analyses specifically examined the relationship between RAT variables and cyberstalking outcomes and the extent to which a specific form of guardianship, online disclosiveness, served as a mediator between online activities and the risk for victimization. Online exposure and a proclivity for social risk-taking were associated with cyberstalking victimization. Levels of online disclosure demonstrated a direct positive impact on cyberstalking victimization, however our findings elucidating the role of online disclosure as a guardianship effort mediating the effects of exposure on cyberstalking victimization were mixed.

Recent years have seen a growing interest in more distributed approaches towards stormwater management, often integrated with other forms of distributed management of urban water such as water demand management technologies. This paper focuses on the role of green roofs (GR), rainwater harvesting (RWH) and greywater reuse and their integration at the building level. A number of models were developed to simulate these systems, and provide design curves able to simultaneously minimise both total runoff volumes and the amount of potable water used in the building (for irrigation and toilet flushing). The models developed were applied to the design of stormwater infrastructure for the building of the National Gallery, in Athens, Greece. A sensitivity analysis of various model parameters was conducted, with results suggesting, inter alia: (i) a significant decrease of total runoff volumes for rainfalls of medium-to-small return periods; (ii) a significant influence of the plant factor on water requirements (with implications for selecting vegetation for GR in a Mediterranean climate); and (iii) a significant impact of latent heat peaking during the months of June and July. The trade-off, on runoff volumes, between percentage of green roof area and the dimensions of the water storage tank was also investigated. The results suggest that the most preferable solution for conserving potable water was RWH combined with greywater recycling, while for runoff minimisation the best option was the combination of green roof and greywater recycling.
