The customer engagement ecosystem

ABSTRACT Consumer engagement has been widely discussed in both the academic and practitioner literature, but there is no consensus about its meaning, what phenomena constitute engagement or what its antecedents and consequences are. Therefore, we propose that the term engagement should be eluded and that more specific terms should be used for the different phenomena. Building on the previous literature, we propose the customer engagement ecosystem, a conceptual model that encompasses brand actions, other actors, customer brand experience, shopping behaviours, brand consumption and brand-dialogue behaviours. The model posits that interactions between these elements are non-linear and reactive; meaning that each action causes a reaction of not only the intended recipient of the message, but the whole ecosystem. Hence, the model reflects the interconnected character of today’s marketing environment. It also recognises the growing importance of empowered consumers by distinguishing different forms of brand dialogue behaviours, which describe customers’ non-purchase focused behaviours.
Prescribing 10,000 Steps Like Aspirin: Designing a Novel Interface for Data-Driven Medical Consultations

Due to the prevalence of personal health tracking, cases of self-logged data being utilized in the clinic are gradually increasing. However, obstacles to clinicians' ability to further adopt such data-driven medical consultations in the existing workflow remain, such as lack of time and poor interoperability. In this paper, we conducted a workshop to design a clinician interface supporting the integration of data-driven consultation into the existing workflow and investigate the role of the interface in situ. After implementing the clinician interface designed based on the workshop results, we observed 32 cases of actual use within the clinical context. We found that our interface, DataMD, helped the clinician construct a new workflow, enhanced the clinician's counseling skills, and facilitated more in-depth conversation. This paper contributes to empirically identifying the role of a clinician interface through a user-centered design approach.
Faster-than-at-speed test for increased test quality and in-field reliability

Faster-than-at-speed testing is an effective approach to screen small delay defects (SDDs) and increase test quality and in-field reliability. This paper presents a novel framework of faster-than-at-speed test to minimize the slack of the sensitized path for each fault. The basic strategy is to use multiple faster-than-at-speed test timings with endpoint masking for each pattern. By performing a detailed analysis of the sensitized path delay for active faults and active endpoints in each pattern, we can minimize the slack for the detectable faults while preventing a large increase in pattern count. We also present methods to maximize the sensitized path delay and further reduce the pattern count under a constraint on the allowable slack size, instead of minimizing the slack. Experimental results for ITC'99 benchmark circuits show the effectiveness of the proposed methods in terms of slack size and sensitized path delay for detectable faults, statistical delay quality level (SDQL) and pattern count.
All-trans Retinoic Acid Enhances Murine Dendritic Cell Migration to Draining Lymph Nodes via the Balance of Matrix Metalloproteinases and Their Inhibitors1

Cancers escape immune surveillance through the manipulation of the host’s immune system. Sequestration of dendritic cells (DCs) within tumor tissues and the subsequent inhibition of their migration is one of the several mechanisms by which tumors induce immunosuppression. In view of recent findings depicting the improvement of tumor immune responses in cancer patients following all-trans retinoic acid (ATRA) treatment, we sought to identify the effects of ATRA on DC mobility in the context of tumor immunotherapy. Our results demonstrate that ATRA, added to differentiating murine bone marrow progenitor cells, enhances the invasive capacity of the resulting DCs. Immature DCs injected intratumorally in mice show increased accumulation in draining lymph nodes, but not in nondraining lymph nodes and spleens, when differentiated in the presence of ATRA. The in vitro migration of mature DCs through the basement membrane matrix toward the lymphoid chemokines CCL19 and CCL21 is enhanced in these cells, albeit not in the presence of a matrix metalloproteinase (MMP) inhibitor. An increase in MMP production with a simultaneous decrease in the production of their inhibitors (tissue inhibitors of matrix metalloproteinase or TIMPs) is provoked by ATRA. This affects the MMP/TIMP balance in DCs, in particular that of MMP-9 and TIMP-1, favoring protease activity and thus allowing for enhanced DC mobilization. In conclusion, this study demonstrates that ATRA is capable of improving DC trafficking in a tumor milieu and, in view of the encouraging results obtained in the clinic, further supports the notion that ATRA might be a valuable chemical adjuvant to current immunotherapeutic strategies for cancer.
A Globally Stabilizing Path Following Controller for Rotorcraft With Wind Disturbance Rejection

This brief addresses the design and experimental evaluation of a global controller to steer a quadrotor vehicle along a predefined path in the presence of constant wind disturbances. The proposed solution consists of a nonlinear adaptive state feedback controller for thrust and torque actuation that: 1) guarantees global convergence of the closed-loop path following error to zero in the presence of constant wind disturbances and 2) ensures that the actuation can be bounded as a function of the position and velocity errors without imposing a maximum for that bound, allowing for high performance control action. A prototyping and testing architecture, developed to streamline the implementation and tuning of the controller, is also described. Simulation results and experimental results, which include a hovering flight in the slipstream of a mechanical fan, are presented to assess the performance and robustness of the proposed controller.
A Unified-Model-Based Analysis of MRAS for Online Rotor Time Constant Estimation in an Induction Motor Drive

Depending on the functional candidates, such as rotor flux, stator voltage, electromagnetic torque, and reactive power, various schemes based on a model reference adaptive system (MRAS) have been proposed to update rotor time constant. In this paper, a unified model for rotor time constant identification based on MRAS in an induction motor drive with indirect field-oriented control is developed. It is shown that kinds of MRAS-based models are of unity in essence and share a unified mathematical expression despite their different implementations, providing a new viewpoint to analyze the estimation models and supplying theoretical basis for evolutions and comparisons among them. Furthermore, to expand the effective range of the estimation model, stator frequency or q-axis stator current must be incorporated into the corresponding adaptive mechanism. From the closed-loop transfer function of the system, established in this paper, the properties of high nonlinearity and strong coupling behind the seemingly simple structure of these MRAS-based identification methods are exposed, paving a basis to improve the performance further. The validity of the proposed theory is verified by simulations and representative experimental results.
Predictors of Literacy and School Attainment among Orphan Heads of Households Involved in a Community-Based Empowerment Program in Semi-Rural Kenya

Completion of primary and secondary education, and literacy, are significant determinants of health and livelihood status in later life. Orphans and vulnerable children (OVC) in sub-Saharan Africa have higher risk of lower education and literacy attainment than non-OVC. The present study evaluates factors associated with the ability to read two simple sentences and increase years of schooling among OVC heads-ofhousehold participating in a multisectoral empowerment program in semi-rural Kenya. Methods of analysis include simple and multivariable quantile regression of school years completed, and simple and multivariable logistic regression of ability to completely read two sentences, primary and secondary completion. Findings show recency of sexual intercourse, orphan type, improved primary drinking water, resilience, self-efficacy, gender, age, household income and program participation are significantly associated with outcomes of interest. Support for multisectoral empowerment programs may successfully target multiple outcomes of interest, including increases in educational attainment.
Effects of increasing amounts of Lupinus albus seeds without or with whole egg powder in the diet of growing pigs on performance

In a growth trial with pigs, the effect of the inclusion of 150 and 300 g of Lupinus albus seeds/kg of feed in the diet was investigated. Parameters studied were: growth, feed utilization, digestibility of nutrients, slaughter and carcass characteristics. Spray dried whole egg powder, a speci®c inhibitor of lectins in L. albus seeds was also added (50 g/kg of feed), with the aim of verifying whether the unfavourable effects of high levels of lupin seeds could be neutralized. Feeding the diet containing 300 g of lupin seeds/kg lowered the average daily gain from 727 to 674 g and feed intake from 2.32 to 2.05 kg, while feed conversion ratio remained unaltered. The presence of whole egg powder in the lupin seed diets did not abolish the negative effects. Apparent faecal digestibility of most nutrients in the diets was not in ̄uenced by addition of lupin seeds or egg powder, except for the crude fat fraction, whereas the digestibility coef®cient increased from 0.51 to 0.61. Crude ®bre digestibility also increased, but only at the lowest lupin seed level. Carcass weight and dressing percentage were lower in the groups fed the highest lupin seed level. Fatty acid pro®le of backfat was determined and slightly higher proportions of C18:1 were observed when lupin seeds were fed. Possible reasons accounting for the lower performance of animals receiving lupin seeds are discussed, but the exact reason could not be derived from this experiment. # 2000 Elsevier Science B.V.

Using data envelopment analysis to compare suppliers for supplier selection and performance improvement

Data envelopment analysis (DEA) has been widely applied to address various decision analysis problems due to its usefulness in evaluating multi‐criterion systems and providing improvement targets for such systems. A supplier selection problem is inherently a multi‐criterion decision problem, and DEA has been applied to evaluate suppliers for an individual product. This paper proposes and demonstrates the application of DEA in evaluating the overall performances of suppliers in a manufacturing firm. A simplified DEA model for supplier selection is first presented to evaluate the overall performances of suppliers with a strategic orientation of being able to reduce the number of suppliers. A case study is then presented to demonstrate supplier performance evaluation using DEA for supplier selection and performance improvement considerations.
Development of Real-time HDTV-to-8K TV Upconverter

Recent reports show that 4K and 8K TV systems are expected to replace HDTV in the near future. 4K TV broadcasting has begun commercially and the same for 8K TV is projected to begin by 2018. However, the availability of content for 8K TV is still insufficient, a situation similar to that of HDTV in the 1990s. Upconverting analogue content to HDTV content was important to supplement the insufficient HDTV content. This upconverted content was also important for news coverage as HDTV equipment was heavy and bulky. The current situation for 4K and 8K TV is similar wherein covering news with 8K TV equipment is very difficult as this equipment is much heavier and bulkier than that required for HDTV in the 1990s. The HDTV content available currently is sufficient, and the equipment has also evolved to facilitate news coverage; therefore, an HDTV-to-8K TV upconverter can be a solution to the problems described above . However, upconversion from interlaced HDTV to 8K TV results in an enlargement of the images by a factor of 32, thus making the upconverted images very blurry. An upconverter with super resolution has been proposed in this study in order to fix this issue.
Interfirm Collaboration in the Shipbuilding Industry: The Shipbuilding Cycle Perspective

This paper investigates the interfirm cooperative strategies of shipbuilding firms. This paper aims to understand the system nature and dynamics of interfirm cooperative strategies adopted by firms in the shipbuilding industry related to the phase of the shipbuilding cycle. A theory-building approach from case studies is applied in this study. The study is based on interviews with managers of the Norwegian, Danish, Polish and Ukrainian shipbuilding firms. In addition, secondary data were collected. Issues relating to the aims of joining cooperative agreements; resources and competences which the shipbuilding firms and their collaborators contribute to joint ventures, strategic alliances and other collaborative arrangements; and how collaborative strategies were related to the phase of the shipbuilding cycle were explored. Implications for further research, practitioners and policy-makers are provided.
Solution of a Divide-and-Conquer Maximin Recurrence

The solution of the divide-and-conquer recurrence\[ M(n)\mathop {\max }\limits_{1 \leqq k < n} (M(k) + M(n - k) + \min (f(k),f(n - k))) \]is found for a variety of functions f. Asymptotic bounds on $M(n)$ are found for arbitrary nondecreasing f, and the exact form of $M(n)$ is determined for f nondecreasing and weakly concave. As a corollary to the asymptotic bounds, it is shown that $M(n)$ remains linear even when f is almost linear. Among the exact forms determined: For $f(x) = \lfloor {\lg x} \rfloor $, the solution is $M(n) = (M(1) + 1)n - \lfloor {\lg n} \rfloor - \nu (n)$ where $\nu (n)$ is the number of 1-bits in the binary representation of n. For $f(x) = \lfloor {\lg x} \rfloor $, the solution is $M(n) = (M(1) + 1)n - \lceil {\lg n} \rceil - 1$, while for $f(x) = \lceil {\lg (x + 1)} \rceil $, thesolution is $M(n) = (M(1) + 2)n - \lfloor {\lg n} \rfloor - \nu (n) - 1$.
Information Technology readiness index for adoption of e-procurement

This paper devises an Information Technology (IT)-readiness index for evaluating the present IT-related status of the government organisations for e-procurement adoption. Understanding the fact that there are many factors influencing the IT-readiness of an organisation, this paper is intended to measure the IT-readiness index considering the most important of these factors. In contrast to the majority of the indices in the literature, the proposed index is built upon defining and collecting data of IT-infrastructure, skilled-people, financial-support and effective-training programmes. Thereafter, IT-readiness index for 11 state government organisations was computed considering the employees' opinions and using multi-criteria decision making techniques.
A randomized controlled trial of internet-based cognitive-behavioural therapy for bulimia nervosa or related disorders in a student population

Background Bulimic eating disorders are common among female students, yet the majority do not access effective treatment. Internet-based cognitive-behavioural therapy (iCBT) may be able to bridge this gap. Method Seventy-six students with bulimia nervosa (BN) or eating disorder not otherwise specified (EDNOS) were randomly assigned to immediate iCBT with e-mail support over 3 months or to a 3-month waiting list followed by iCBT [waiting list/delayed treatment control (WL/DTC)]. ED outcomes were assessed with the Eating Disorder Examination (EDE) at baseline, 3 months and 6 months. Other outcomes included depression, anxiety and quality of life. Results Students who had immediate iCBT showed significantly greater improvements at 3 and 6 months than those receiving WL/DTC in ED and other symptoms. Conclusions iCBT with e-mail support is efficacious in students with bulimic disorders and has lasting effects.
Inspiratory muscle workload due to dynamic intrinsic PEEP in stable COPD patients: effects of two different settings of non-invasive pressure-support ventilation.

BACKGROUND In severe stable hypercapnic COPD patients the amount of pressure time product (PTP) spent to counterbalance their dynamic intrinsic positive end expiratory pressure (PEEPi,dyn) is high: no data are available on the best setting of non invasive pressure support ventilation (NPSV) to reduce the inspiratory muscle workload due to PEEPi,dyn. METHODS The objectives of this randomised controlled physiological study were: 1. To measure the inspiratory muscle workload due to PEEPi,dyn 2. To measure the effects on this parameter of two settings of NPSV in stable COPD patients with chronic hypercapnia admitted in a Pulmonary Division of two Rehabilitation Centers. Twenty-three stable COPD patients with chronic hypercapnia on domiciliary nocturnal NPSV for 30 +/- 20 months were submitted to an evaluation of breathing pattern, PEEPi,dyn, inspiratory muscle workload and its partitioning during both assisted and unassisted ventilation. Two settings of NPSV were randomly applied for 30 minutes each: i- "at patient's comfort" (C): Inspiratory pressure support (IPS) was the maximal tolerated pressure able to reduce awake PaCO2 with the addition of a pre-set level of external PEEP (PEEPe); ii- "physiological setting" (PH): the level of IPS able to achieve a > 40% and < 90% decrease in transdiaphragmatic pressure in comparison to spontaneous breathing (SB). A PEEPe level able to reduce PEEPi,dyn by at least 50% was added. RESULTS During SB the tidal diaphragmatic pressure-time product (PTPdi/b) was 17.62 +/- 7.22 cmH2O*sec, the component due to PEEPi,dyn (PTPdiPEEPi,dyn) being 38 +/- 17% (range: 16-65%). Compared to SB,PTPdiPEEPi,dyn was reduced significantly with both settings, the reduction being greater with PH compared to C. CONCLUSIONS In conclusion in severe COPD patients with chronic hypercapnia the inspiratory muscle workload due to PEEPidyn is high and is reduced by NPSV at a greater extent when ventilator setting is tailored to patient's mechanics.
Coupled Dictionary Learning for Unsupervised Feature Selection

Unsupervised feature selection (UFS) aims to reduce the time complexity and storage burden, as well as improve the generalization performance. Most existing methods convert UFS to supervised learning problem by generating labels with specific techniques (e.g., spectral analysis, matrix factorization and linear predictor). Instead, we proposed a novel coupled analysis-synthesis dictionary learning method, which is free of generating labels. The representation coefficients are used to model the cluster structure and data distribution. Specifically, the synthesis dictionary is used to reconstruct samples, while the analysis dictionary analytically codes the samples and assigns probabilities to the samples. Afterwards, the analysis dictionary is used to select features that can well preserve the data distribution. The effective L2p-norm (0 < p <1) regularization is imposed on the analysis dictionary to get much sparse solution and is more effective in feature selection.We proposed an iterative reweighted least squares algorithm to solve the L2p-norm optimization problem and proved it can converge to a fixed point. Experiments on benchmark datasets validated the effectiveness of the proposed method
Organizational Levels of Analysis of Communication Satisfaction and Identification in Relation to Job Satisfaction

The central theme of this article is burnout and sleep quality among head teachers. The paper aims to investigate whether there is a relationship between the burnout dimensions exhaustion, cynicism, and competence and sleep quality. Adopting a quantitative approach, the most widely acknowledge tool for measuring burnout, the Maslach burnout inventory (MBI), was incorporated in the questionnaire. The Pittsburgh Sleep Quality Index was used to measure sleep quality. The questionnaire was then distributed to 600 head teachers in Malaysia. Responses to the MBI revealed that head teachers in Malaysia exhibited a high level of burnout. Respondents also reported a low level of sleep quality. In addition a negative relationship exists between burnout and sleep quality. Expansion of the quantitative data with respondents’ comments indicated that head teachers perceived that their workload has reached a level that they cannot sustain and which constitutes a serious risk their quality of life. This article pinpoints the many “problems” faced by head teachers how it causes burnout and also thereafter affect their sleep quality. This study also indicated the need for simultaneous assessment of burnout and sleep quality.
Influences on Nonword Repetition in Young Children

Nonword repetition (NWR) tasks have become popular in recent years as measures of phonological short term memory (PSTM) in research settings, and as potential markers of language impairment in clinical settings. This has increased interest in the subskills that potentially NWR performance. The current study investigated the influence of PSTM, vocabulary skills, articulatory output skills, literacy, and speech perception on NWR in children ages 4;0-6;5. Partial correlations and regression analysis were used to establish an in-depth picture of the skills that constrain NWR, and to differentiate the skills that underlie this measure when the language skills of test takers and the wordlikeness of NWR items were taken into account. Results indicated that both PSTM and vocabulary were independently related to NWR performance when the entire sample was considered. When the sample was divided by language scores, higher-scoring participants’ NWR performance was influenced by PSTM, while only vocabulary scores were related to NWR performance in lower-language scoring children. Wordlikeness of nonword items also affected the skills related to NWR performance, in that scores on highly wordlike stimuli were principally related to vocabulary skills, while scores on less wordlike stimuli were significantly related to PSTM only. These results indicate that despite its popularity as a measure of PSTM, NWR cannot be considered a monolithic measure of this skill in all cases. In general, NWR performance in the current study were influenced by both PSTM and vocabulary skills, and that influence varied with the language skill of participants and the wordlikness of NWR items.
Does Transparency Overcome Conflicts of Interest? Evidence from Investment Managers and Their Brokers

The relationship between investment managers and brokers has been identified by regulators in Europe and the US as a potential source of conflicts of interest, with investment managers buying a bundle of services – including trade execution and sell-side research – from brokers at the expense of the investors. Little systematic evidence is available, however, on this complex relationship. This paper reports the outcome of a landmark ruling under the UK Freedom of Information Act, whichallowed us to obtain, from UK public pension funds, information on commissions, trading activity, payments for research and other variables. Following an important regulatory change in the UK that increased transparency, we find that average commission rates have fallen, and the proportion spent on research – rather than execution – has increased slightly. However, trading has increased significantly: the average churn rate increased from 27% to 73% from 2005-08, resulting in total commission payments to brokers nearly doubling.
