Who to show the ad to? Behavioral targeting in Internet advertising
Authors: Xiong Wei , Xiong Ziyi , Tian Tina 
Published: March 2022

PurposeThe performance of behavioral targeting (BT) mainly relies on the effectiveness of user classification since advertisers always want to target their advertisements to the most relevant users. In this paper, the authors frame the BT as a user classification problem and describe a machine learning–based approach for solving it.Design/methodology/approachTo perform such a study, two major research questions are investigated: the first question is how to represent a user’s online behavior. A good representation strategy should be able to effectively classify users based on their online activities. The second question is how different representation strategies affect the targeting performance. The authors propose three user behavior representation methods and compare them empirically using the area under the receiver operating characteristic curve (AUC) as a performance measure.FindingsThe experimental results indicate that ad campaign effectiveness can be significantly improved by combining user search queries, clicked URLs and clicked ads as a user profile. In addition, the authors also explore the temporal aspect of user behavior history by investigating the effect of history length on targeting performance. The authors note that an improvement of approximately 6.5% in AUC is achieved when user history is extended from 1 day to 14 days, which is substantial in targeting performance.Originality/valueThis paper confirms the effectiveness of BT on user classification and provides a validation of BT for Internet advertising.
The role of public relations in shaping service ecosystems for social change
Authors: Fehrer Julia A. , Baker Jonathan J. , Carroll Craig E. 
Published: March 2022

PurposeWicked problems require holistic and systemic thinking that accommodates interdisciplinary solutions and cross-sectoral collaborations between private and public sectors. This paper explores how public relations (PR) – as a boundary-spanning function at the nexus of corporate and political discourse – can support societies to tackle wicked problems.Design/methodology/approachThis conceptual paper synthesizes literature on PR with a service ecosystem perspective. The authors use the service ecosystem design framework to structure the PR literature and develop a model of service ecosystem shaping for social change, which highlights the important role that PR can play in shaping processes.FindingsThe authors explicate how PR can (1) facilitate value cocreation processes between broad sets of stakeholders that drive positive social change, (2) shape institutional arrangements in general and public discourse in particular, (3) provide a platform for recursive feedback loops of reflexivity and (re)formation that enables discourse to ripple through nested service ecosystems and (4) guide collective shaping efforts by bringing stakeholder concerns and beliefs into the open, which provides a foundation for collective sense-making of wicked problems and their solutions.Originality/valueThis paper explains the complexity of shaping service ecosystems for positive social change. Specifically, it highlights how solving wicked problems and driving social change requires reconfiguration of the institutional arrangements that guide various nested service ecosystems. The authors discuss in detail how PR can contribute to the shaping of service ecosystems for social change and present a future research agenda for both service and PR scholars to consider.

Authors: Zhang Rong , Chang Yu-Teng 
Published: March 2022

PurposeThe purpose of this research is to explore the critical success factors of mobile animation games, by exploring the game itself, information systems, game motivation and promotional activities, as well as conducting research and analysis on mobile animation game players.Design/methodology/approachThis research used the Analysis Hierarchy Process (AHP) method and the consistent fuzzy preference relationship for data analysis. In this study, collect 1,286 valid questionnaires through online questionnaire surveys. And comparing the two games “Legend Showdown” and “Tower of Gods and Demons”, players believe that the more successful mobile animation game is “Legend Showdown”.FindingsThrough experimental design, and the consistent fuzzy preference relationship for data analysis. The results found that the critical factors considered by the player in relation to the mobile animation game were firstly the information system, followed by promotional activities, game motivation and finally the game itself.Research limitations/implications Because this research does not involve the concept of fuzzy theory at all, it is easy to produce subjective, uncertain and ambiguity issues when comparing pairwise. We recommended that follow-up researchers can use fuzzy semantic preference relations to solve this problem.Originality/valueThis study proposed a new approach that takes the critical factors for the mobile animation game. According to the research results, the critical success factor of mobile animation games is the information system, as it could provide a reference direction for game manufacturers when designing or formulating marketing strategies in the future.

Authors: Acharya Keshav K. , Scott John 
Published: March 2022

PurposeCorruption and dishonesty in the political and bureaucratic realms have impeded the ability of local governments to provide services and social justice in Nepali society. In light of this, the purpose of this research is to answer the key research question: what are the possibilities and limitations of local government in implementing constitutionally guaranteed rights in order to transform local communities?Design/methodology/approachThis study gathered qualitative data from 14 local governments in seven provinces. A total of 56 in-depth interviews were held with elected representatives, political parties, and government officials at both the national and local levels. Both open-ended and open-structured questionnaires were employed for the interviews.FindingsThe results indicate that capacity is a major constraint for local governments, which should be addressed to achieve successful local governance, inclusive citizen engagement, and strong technical, administrative and fiscal capabilities. Lack of local autonomy, political conflict and social class differences, external engagement, and conservative hierarchic government bureaucracy are major hurdles to growing capacity.Originality/valueThis paper analyses the capacity of newly restructured local governments through qualitative approach. It attempts to understand to what extent the Nepali local governments are capable in delivering the services at the local level as closest unit of the citizens.

AbstractObjectiveThe aim of this study was to assess the added value of the soluble fms‐like tyrosine kinase‐1 (sFlt‐1) and placental growth factor (PlGF) ratio for adjusting the periodicity of ultrasound examinations in early‐onset fetal growth restriction (FGR) and small for gestational age (SGA).DesignA prospective, observational study.SettingTertiary referral hospital.PopulationOne hundred and thirty‐four single pregnancies with ultrasonographic estimated fetal weight (EFW) below the 10th centile between 20+0 and 31+6 weeks of gestation with antegrade umbilical artery flow.MethodsThe time from Doppler and sFlt‐1/PlGF assessment to delivery was recorded and classified into four ranges: <1, <2, <3 and <4 weeks.Main outcome measuresSensitivity (Sn), specificity (Sp), positive predictive value (PPV) and negative predictive value (NPV) of sFlt‐1/PlGF values to predict the time to delivery.ResultsIn the SGA cohort, the NPV calculated for an sFlt‐1/PlGF cut‐off value of 38 was 100% for delivery before 3 weeks, and 98% for delivery before 4 weeks after diagnosis (95% CI 0.89–1.00). In the FGR cohort, the NPV calculated for an sFlt‐1/PlGF cut‐off value of 38 was 100% for delivery before 2 weeks after diagnosis (95% CI 0.92–1.00). By contrast, more than 50% of cases with an sFlt‐1/PlGF value of >85 required an elective delivery before 1 week.ConclusionssFlt‐1/PlGF values in early‐onset SGA and FGR are predictive of the time to delivery and could be used for planning fetal surveillance, by reducing the frequency of ultrasound in cases with sFlt‐1/PlGF < 38 and by providing closer follow‐up in cases with sFlt‐1/PlGF >85.Tweetable abstractsFlt‐1/PlGF values in early‐onset SGA/FGR could be used in addition to Doppler for planning fetal surveillance.

AbstractAimThe aim of this study was to evaluate if the application of Artificial Intelligence (AI) Colonoscopy CLN (ENDO‐AID) could increase the polyp detection rate (PDR).Methods and MaterialsA single center retrospective study was performed in Tin Shui Wai Hospital. PDR in CLN from 11/2020 to 03/2021 after the application of ENDO‐AID (AI group) was compared to the cases from 12/2019 to 11/2020 before the application of the practice (non‐AI group). Procedures were performed by a single endoscopist with experience in performing > 3,000 CLN. Variables, such as patients' demographic data, indications, incidence of PDR, Boston Bowel Preparation Scale BBPS, withdrawal time, post CLN complication rate between the 2 groups, were compared. Categorical and continuous variables were analyzed by using the Chi‐Square test (Fisher exact test if appropriate) and Mann‐Whitney test respectively. Results were considered to be significant if p‐value < 0.05.ResultsTotal 234 patients were recruited. 115 patients (49.1%) were in the non‐AI group while 119 patients (50.9%) were in the AI group. The mean age of the non‐AI was higher than the AI group (65.3 vs 59.2, p< 0.001*), otherwise, there was no significant difference in sex (p = 0.05), percentage of smokers (20.8% vs 27.7%, p = 0.22), past medical history of IBD (0 vs 0, p = 1.0), family history of colorectal cancer (9 vs 9, p = 0.94), indications for CLN (e.g. follow up CLN for polyp/ cancer, per‐rectal bleeding, altered bowel habit etc. p > 0.05), BBPS (7.88 vs 8.04, p = 0.217), withdrawal time (7.65 min vs 7.48 min, p = 0.935), completion rate (95.6% vs 98.3%, p = 0.27) and complication rate (0% in both groups,p=1.0) between groups. In the contrary, PDR was significantly higher in the AI group than the non‐AI group (64.7% vs 46.0%, p = 0.003*). Besides, adenoma detection rate was also found significantly higher in the AI group than the non‐AI group (52.9% vs 37.4%, p = 0.017*).ConclusionsAI CLN can improve the PDR.

Published: March 2022

AbstractIntroductionT4 nasopharyngeal carcinoma (NPC) with close proximity to critical organs at risk (OARs) is usually underdosed during radiotherapy in order to respect radiation constraints. N3 disease has high risk of distant metastasis. Induction chemotherapy (IC) provides advantages of sparing of OARs during subsequent chemoradiotherapy (CCRT) and early eradication of micrometastasis. However, factors predicting successes of IC in this patient group are not well‐studied.Methods104 T4 or N3 NPC patients were retrospectively reviewed during 2007–2018. They were planned for IC followed by CCRT using intensity‐modulated radiotherapy.ResultsIn the whole group, five‐year failure‐free survival (FFS), locoregional failure‐free survival (LRFS), distant failure‐free survival (DFFS) and overall survival (OS) were 40.9%, 45.7%, 46.9% and 53.6% respectively. Isolated marginal failure rate was 5% (4/80) among patients with primary tumours located close to critical OARs. Pre‐IC gross tumour volume primary (GTVp) total volume > 110 cm3 correlated with worse five‐year LRFS (OR 6.37, P = 0.008), DFFS (OR 8.89, P = 0.003) and OS (OR 50.12, P < 0.001). In the T4 subgroup, IC improved D100% GTVp from 61.39 Gy to 64.71 Gy (P < 0.001) and V100% GTVp from 98.78% to 99.28% (P < 0.001).ConclusionOur study demonstrated improved dosimetric parameters and low isolated marginal failure rate. It supported the use of IC and CCRT for tumours located close to critical OARs. Further research is warranted to compare predictive roles of pre‐ and post‐IC tumour volumes. For high‐risk patients being defined by pre‐IC volume or other prognostic models, treatment escalation should be considered.

AbstractPurposeTo present a case study with Epidermolysis bullosa (EB) in Cyprus and to determine the nursing care plan, explaining the nursing interventions and showing the importance of nursing care of patients with EB.MethodsLiterature review on EB and semi‐structured interviews commenced through a direct discussion with open‐ended questions to the research subject as well as to a close relative describing his feelings, experiences, and concerns about the disease.FindingsThematic analysis approach was used to identify and analyze patterns in the data. Then, data were synthesized using the standardized nursing terminology of NANDA‐I and the Nursing Interventions Classification. The accuracy of the diagnoses and the appropriateness of the nursing interventions were supported by the positive health outcomes of the patient.ConclusionsNurses should apply evidence‐based practice interventions for EB wound care, pain management, nutrition, psychological and social support to these patients.Implications for nursing practiceAlthough EB is classified in the category of rare diseases, the presentation of a case study in Cyprus and the nursing care plan contribute further bibliographically to the holistic and at the same time individualized nursing practice.
Dummy and effects coding variables in discrete choice analysis
Authors: Hu Wuyang , Sun Shan , Penn Jerrod , Qing Ping 
Published: March 2022

AbstractDiscrete choice models typically incorporate product/service attributes, many of which are categorical. Researchers code these attributes in one of two ways: dummy coding and effects coding. Whereas previous studies favor effects coding citing that it resolves confounding between attributes, our analysis demonstrates that such confounding does not exist in either method, even when a choice model contains alternative specific constants. Furthermore, we show that because of the lack of understanding of the equivalence between the two coding methods, a sizeable number of previously published articles have misinterpreted effects coded results. The misinterpretation generates conflicting preference ordering and renders t‐statistics, marginal willingness to pay, as well as consumer surplus/compensating variation estimates invalid. We show that severe misinterpretation occurs for any categorical attribute that contains more than two discrete levels. The frequency of two‐level attributes used in discrete choice analyses may have led some past studies to overlook this error. Given its equivalence and lower likelihood of misinterpretation, we recommend dummy coding.

SummaryAlthough patient safety related to airway management has improved substantially over the last few decades, life‐threatening events still occur. Technical skills, clinical expertise and human factors contribute to successful airway management. Checklists aim to improve safety by providing a structured approach to equipment, personnel and decision‐making. This audit investigates adherence to our institution's airway checklist from 1 June 2016 to 31 May 2021. Inclusion criteria were procedures requiring airway management and we excluded all procedures performed solely under regional anaesthesia, sedation without airway management or paediatric and cardiovascular surgery. The primary outcome was the proportion of wholly performed pre‐induction checklists. Secondary outcomes were the pattern of adherence over the 5 years well as details of airway management, including: airway management difficulties; time and location of induction; anaesthesia teams in operating theatres (including teams for different surgical specialities); non‐operating theatre and emergency procedures; type of anaesthesia (general or combined); and urgency of the procedure. In total, 95,946 procedures were included. In 57.3%, anaesthesia pre‐induction checklists were completed. Over the 5 years after implementation, adherence improved from 48.3% to 66.7% (p < 0.001). Anticipated and unanticipated airway management difficulties (e.g. facemask ventilation, supraglottic airway device or intubation) defined by the handling anaesthetist were encountered in 4.2% of all procedures. Completion of the checklist differed depending on the time of day (61.3% during the day vs. 35.0% during the night, p < 0.001). Completion also differed depending on location (66.8% in operating theatres vs. 41.0% for non‐operating theatre anaesthesia, p < 0.001) and urgency of procedure (65.4% in non‐emergencies vs. 35.4% in emergencies, p < 0.001). A mixed‐effect model indicated that urgency of procedure is a strong predictor for adherence, with emergency cases having lower adherence (OR 0.58, 95%CI 0.49–0.68, p < 0.001). In conclusion, over 5 years, a significant increase in adherence to an anaesthesia pre‐induction checklist was found, and areas for further improvement (e.g. emergencies, non‐operating room procedures, night‐time procedures) were identified.
Practical extended use of antimicrobial silver (PExUS)
Authors: May Andrew , Kopecki Zlatko , Carney Bernard , Cowin Allison 
Published: March 2022

AbstractBackgroundAntimicrobial silver has had a role in wound antisepsis throughout history and, with the rise in acquired antibiotic resistance, silver dressings are once again commonly used. Issues with silver dressings include the important environmental consideration of nanoparticle manufacture, and the significant financial cost of these products. One solution to these problems may be to adopt an opened‐but‐unused model of wound care whereby dressing materials are used in piecemeal fashion and excess stored in between dressing changes. Due to a lack of literature on the topic, this project was designed with the aim of testing the antimicrobial efficacy of available silver dressings during storage after opening.MethodsFour commonly used silver dressings were tested for antimicrobial activity using a zone of inhibition assay against clinically important pathogens. The assay was performed on opening of dressings and repeated over 3 months in storage at 4, 25 or 37°C. Analysis was performed using repeated measures ANOVA. Swab cultures were taken at each simulated dressing change to detect microbial contamination of the dressings during storage.ResultsThere was no effect of time or storage temperature on the zone of inhibition over the 12 week test period. No swabs taken returned culture consistent with microbial contamination of stored dressings.ConclusionOpened silver dressings maintain antimicrobial activity for at least 12 weeks in storage and are resistant to contamination. An opened‐but‐unused model for wound care is likely to improve cost‐effectiveness while preserving effectiveness and safety.
