This paper aims to enhance the reliability of self-validating multifunctional sensors.

An effective fault detection, isolation and data recovery (FDIR) strategy by using kernel principal component analysis (KPCA) coupled with gray bootstrap and fault reconstruction methods.

The proposed FDIR strategy is able to the address fault detection, isolation and data recovery problem of self-validating multifunctional sensors efficiently.

A KPCA-based model which can overcome the limitation of existing linear-based models is used to achieve the fault detection task. By using gray bootstrap method, the position of all faulty sensitive units can be calculated even under the multiple faults situation. A reconstruction-based contribution method is adopted to evaluate the amplitudes of the fault signals, and the fault-free output of the faulty sensitive units can be used to replace the fault output.

This paper aims to explore how enforced forms of social isolation arising from the first COVID-19 lockdown influenced experiences of problem substance use, relapse and coping strategies for recovery in individuals engaging with harm reduction recovery services.

A qualitative semi-structured interview design was adopted for this research. Seven participants were recruited from a harm reduction recovery organisation. During their initial interview, participants volunteered information regarding their experience of the first lockdown due to emerging concerns of the COVID-19 pandemic. Participants completed a second semi-structured interview at the end of the first lockdown regarding their experience of enforced isolation during this time.

Three themes identified from the analysis were isolation resulting in hindered human capabilities; adjusting to a new normal: an individual experience; and unexpected benefits to recovery resulting from isolation. While some participants reported boredom, loneliness and relapse events, others reported that the national response to the virus did not adversely affect them as they had already adjusted to living in a state of anxiety, isolation and uncertainty. These findings illuminate negative, neutral and positive aspects of substance use recovery throughout the COVID-19 lockdown as well as highlighting the complex and individualised role that social connectedness plays in relapse occurrence.

Participants reported differences in how they were affected by the pandemic, leading to theoretical implications for the effect of social isolation on recovery. For this reason, individuals with a history of dependency should be considered potentially vulnerable to the effects of enforced isolation and should be supported accordingly.

This study used Data Envelopment Analysis (DEA) to measure and evaluate the operational efficiency of 26 isolation hospitals in Egypt during the COVID-19 pandemic, as well as identifying the most important inputs affecting their efficiency.

To measure the operational efficiency of isolation hospitals, this paper combined three interrelated methodologies including DEA, sensitivity analysis and Tobit regression, as well as three inputs (number of physicians, number of nurses and number of beds) and three outputs (number of infections, number of recoveries and number of deaths). Available data were analyzed through R v.4.0.1 software to achieve the study purpose.

Based on DEA analysis, out of 26 isolation hospitals, only 4 were found efficient according to CCR model and 12 out of 26 hospitals achieved efficiency under the BCC model, Tobit regression results confirmed that the number of nurses and the number of beds are common factors impacted the operational efficiency of isolation hospitals, while the number of physicians had no significant effect on efficiency.

The limits of this study related to measuring the operational efficiency of isolation hospitals in Egypt considering the available data for the period from February to August 2020. DEA analysis can also be an important benchmarking tool for measuring the operational efficiency of isolation hospitals, for identifying their ability to utilize and allocate their resources in an optimal manner (Demand vs Capacity Dilemma), which in turn, encountering this pandemic and protect citizens' health.

Despite the intensity of studies that dealt with measuring hospital efficiency, this study to the best of our knowledge is one of the first attempts to measure the efficiency of hospitals in Egypt in times of health' crisis, especially, during the COVID-19 pandemic, to identify the best allocation of resources to achieve the highest level of efficiency during this pandemic.

Describes a study to measure the quality of service provided by food‐poisoning surveillance agencies in England and Wales in terms of the requirements of a representative consumer ‐ the egg producing industry ‐ adopting “egg associated” outbreak investigation reports as the reference output. Defines and makes use of four primary performance indicators: accessibility of information; completeness of evidence supplied in food‐poisoning outbreak investigation reports as to the sources of infection in “egg‐associated” outbreaks; timeliness of information published; and utility of information and advice aimed at preventing or controlling food poisoning. Finds that quality expectations in each parameter measured are not met. Examines reasons why surveillance agencies have not delivered the quality demanded. Makes use of detailed case studies to illustrate inadequacies of current practice. Attributes failure to deliver “accessibility” to a lack of recognition on the status or nature of “consumers”, combined with a self‐maintenance motivation of the part of the surveillance agencies. Finds that failures to deliver “completeness” and “utility” may result from the same defects which give rise to the lack of “accessibility” in that, failing to recognize the consumers of a public service for what they are, the agencies feel no need to provide them with the data they require. The research indicates that self‐maintenance by scientific epidemiologists may introduce biases which when combined with a politically inspired need to transfer responsibility for food‐poisoning outbreaks, skew the conduct of investigations and their conclusions. Contends that this is compounded by serious and multiple inadequacies in the conduct of investigations, arising at least in part from the lack of training and relative inexperience of investigators, the whole conditioned by interdisciplinary rivalry between the professional groups staffing the different agencies. Finds that in addition failures to exploit or develop epidemiological technologies has affected the ability of investigators to resolve the uncertainties identified. Makes recommendations directed at improving the performance of the surveillance agencies which, if adopted will substantially enhance food poisoning control efforts.

The purpose of this paper is to explore two research questions: how do people with concurrent substance abuse and mental health disorders (concurrent conditions) experience and describe meaningful activities? And how do meaningful activities influence the recovery process?

This qualitative study uses an explorative and interpretive design in a phenomenological-hermeneutic approach. Transcribed interviews are analysed using a phenomenological-hermeneutic method for researching lived experience. The study was submitted to the Norwegian Center for Research Data where it was approved (Case No. 54661).

Structural analysis resulted in three overarching themes: achieving a positive identity through actions and feeling worthwhile; physically outside but inside the norms of society, and idleness, isolation, and obstacles on the road to recovery. Meaningful activities, considered a cornerstone in the recovery process, vary widely and are primarily described in social contexts, thereby confirming the significance of social aspects of recovery in addition to recovery as an individual journey. The findings also show that experiencing meaningful activities contributes to recovery capital and the development of recovery-promotive identities.

The study consisted of a small sample size, recruited at one location which served as a primary research limitation.

This paper provides insights for health care practitioners and health care decision makers regarding the importance of meaningful activities viewed through a recovery perspective.

Few studies to date have used a comprehensive approach to describe the influence of experiencing meaningful activities on the recovery process.

This study aims to explore whether frontline employees' service recovery performance as well as customers' recovery satisfaction (RS) act as mediating mechanisms that simultaneously transmit the positive influence of an integrated service recovery system (SRS) on customers' service loyalty (SL).

A total of 134 useable retail banking branch cases (including responses from 134 branch heads, 439 frontline employees and 941 customers) were used to test our model using the partial least squares structural equation modeling (PLS-SEM) approach.

Service recovery system, measured as a higher-order multidimensional construct, has a strong and positive influence on customers' SL. Besides, service recovery performance partially mediates, along with RS, the relationship between SRS and SL. Finally, customers' recovery satisfaction has the strongest influence on service loyalty.

This study strongly suggests that practitioners not only focus on implementing an effective SRS but also on leveraging service recovery performance and RS to build sustained customers' loyalty. Practitioners must provide more attention to training their frontline employees, reward and recognize employees and continually evaluate their employees' recovery efforts.

The role of frontline employees' service recovery performance and customers' RS as mediating mechanisms in transmitting the positive effect of SRS on customers' SL is investigated using the combined perspectives of social-technical system theory and interdependence theory.

This paper will use the latest research within the extended transaction models and replication methods to illustrate how to design distributed enterprise resource planning (ERP) software with high performance and availability. In a distributed ERP system, an e‐commerce server is an ordinary sales location with or without its own stock, and, therefore, the e‐commerce system is totally integrated in the ERP system. The author has cooperated with one of the major ERP software companies in analyzing how the company can design such a distributed version of their ERP system.

When a failure occurs with a self-service technology (SST), do customers want to give back the “self” in self-service? The authors explore employee’s role in a self-service failure and how the presence of other customers can change that role. Specifically, they examine how the self-monitoring of customers behavior during a failure can change recovery preferences.

Data were collected from customers of a movie self-service ticket kiosk and a grocery self-checkout. Three experiments were conducted.

Results from these studies find that customers want employees to fully take over a transaction after a failure if it takes place in isolation. If other patrons are present or waiting in line, then customers prefer the employee to simply correct the problem and let them complete the transaction. Finally, the servicescape along with the presence of other customers in a self-service area can induce self-monitoring behaviors and alter optimal recovery strategies.

These findings have implications on the appropriate amount of recovery assistance customers need in a self-service experience.

This research reveals the social and functional complexities associated with executing a satisfactory SST failure recovery, particularly with respect to determining the extent to which the employee or customer should control the attempt.

This is the first study to examine the employee’s role in a self-service failure. While other studies have examined customers’ intentions in a self-service failure, authors examine how a service provider can assist in the recovery of a self-service failure.

The aim of the study is to explore the experience of eating disorder support group participants. The research question is “What is the experience of adults recovering from an eating disorder in a professionally-led monthly support group?”

This qualitative study explored the experience of adults recovering from an eating disorder in a professionally-led monthly support group. Participants were 18 adults recovering from an eating disorder who attended a monthly support group. The data were collected using an online anonymous survey and then analysed using a thematic analysis.

The main themes that emerged were: (1) sharing the pain and promise, (2) cautions and concerns and (3) facilitators have influence. The findings indicate that the support group provided a safe space to share their lived experience, that it reduced stigma and isolation, and improved participants' motivation and engagement. Moreover, the results revealed some challenges to the functioning of the group. These included management of discussions and dominant members, need for psycho-educational information and managing intense feelings, relating to body-related comparison and other mental disorder comorbidities.

This is the first study highlighting the valuable role of the facilitator in balancing content with compassion, in ensuring safety in the group, and potentially fulfilling a valuable education function in supporting participants in their eating disorder recovery journey.

The purpose of this paper is to uncover the desired qualities and behaviours that patients believe general practitioners (GPs) should have in medical (service recovery) encounters. In particular, the authors try to reveal the qualities and behaviours of GPs that patients value, to understand the underlying benefits that they look for during personal (service recovery) encounters, and to graphically illustrate the findings in a so‐called hierarchical value map. This will prove to be important in order to understand patients' needs and desires correctly.

An exploratory research study using the qualitative laddering interviewing technique was regarded as appropriate as it allows researchers to gain a deeper insight into an underdeveloped research subject. In total, in‐depth laddering interviews with 38 respondents were conducted.

In case of a service recovery encounter, patients believe that GPs need to show competence, friendliness and empathy in order to restore trust in them. GPs should also listen actively and do the appropriate checks in order to find the root cause of the problem. “Health” was the main value sought by patients. This value is considered by patients to be the gateway to moving on with their everyday lives and search the attainment of other values such as well‐being, belongingness, accomplishment, and self‐realization. Moreover, respondents would like to gain knowledge about their disease in order to prevent them in the future and to have some sense of control over the decision of the treatment. Patients also want a more active role in the medical (service recovery) encounter, which calls for a more shared approach by GPs in the interaction with their patients.

This paper gives a valuable first insight into the desired qualities and behaviours of GPs during medical (service recovery) encounters. The study results especially indicate that complaining patients are people first and patients second, where the primary importance is the satisfaction of basic social needs. The fact that this study has revealed the highest number of values in published laddering studies so far shows how crucial these medical (service recovery) encounters in general and GP qualities and behaviours in particular are for patients. Another strong contribution of this paper is the finding that all the identified concepts from the laddering interviews that are shown in the hierarchical value maps must not been seen in strict isolation, as in previous research, but have to be understood as a network of interrelated concepts.
