Assisted reverse electrodialysis for CO2 electrochemical conversion and treatment of wastewater: A new approach towards more eco-friendly processes u…
2020
Abstract In this paper, the utilization of assisted reverse electrodialysis (A-RED), recently used for pre-desalination, is proposed as a general method to reduce the energy requirements of electrolysis processes and evaluated for two model processes: (i) the cathodic conversion of carbon dioxide to formic acid; (ii) the anodic treatment of water contaminated by organics. In A-RED, two solutions with different salt content and an external potential difference, applied in the direction of the natural salinity gradient, are both used to drive redox processes. It was shown, for the first time, that the cathodic conversion of CO2 to formic acid can be performed by both reverse electrodialysis (…
Example, please! Comparing the effects of single customer reviews and aggregate review scores on online shoppers' product evaluations
2014
Many websites of online retail stores display two forms of electronic word of mouth on a single product site, namely single customer reviews and aggregate review scores. This study compares the effects of simultaneously presented single customer reviews and aggregate review scores on product evaluations of visitors of online retail stores. We hypothesize that well-argued single customer reviews should be more influential than aggregate review scores that display the mean rating of all published reviews of a product. Drawing on a 2 × 2 factorial online experiment, we show that a single customer review is effective, even when potential buyers do not perceive it as representing overall custome…
A systematic review of maternal smoking during pregnancy and fetal measurements with meta-analysis
2017
Maternal smoking during pregnancy is linked to reduced birth weight but the gestation at onset of this relationship is not certain. We present a systematic review of the literature describing associations between maternal smoking during pregnancy and ultrasound measurements of fetal size, together with an accompanying meta-analysis. Studies were selected from electronic databases (OVID, EMBASE and Google Scholar) that examined associations between maternal smoking or smoke exposure and antenatal fetal ultrasound measurements. Outcome measures were first, second or third trimester fetal measurements. There were 284 abstracts identified, 16 papers were included in the review and the meta-anal…
Associations between structures, processes and outcomes in inter-municipal cooperation in out-of-hours services in Norway: A survey study
2020
Abstract Inter-municipal cooperation (IMC) has gained widespread recognition as a beneficial strategy for improving efficiency and quality in the provision of out-of-hours emergency care services (OOH services). Little attention, however, has been given to the additional costs of cooperation and the relational processes through which benefits and costs are likely to result. Based on survey data from 266 (77%) Norwegian municipalities involved in IMC in OOH services in 2015, this study aimed to investigate how the structure (governance form, complexity and stability) and quality (trust and consensus) of cooperation processes interact to influence the perceived outcomes (benefits and costs) o…
Incidence of long COVID-19 in people with previous SARS-Cov2 infection: a systematic review and meta-analysis of 120,970 patients
2022
The long-term consequences of the coronavirus disease 19 (COVID-19) are likely to be frequent but results hitherto are inconclusive. Therefore, we aimed to define the incidence of long-term COVID signs and symptoms as defined by the World Health Organization, using a systematic review and meta-analysis of observational studies. A systematic search in several databases was carried out up to 12 January 2022 for observational studies reporting the cumulative incidence of long COVID signs and symptoms divided according to body systems affected. Data are reported as incidence and 95% confidence intervals (CIs). Several sensitivity and meta-regression analyses were performed. Among 11,162 papers …
The Role of Artificial Intelligence in Social Media Big data Analytics for Disaster Management -Initial Results of a Systematic Literature Review
2018
When any kind of disaster occurs, victims who are directly and indirectly affected by the disaster often post vast amount of data (e.g., images, text, speech, video) using numerous social media platforms. This is because social media has recently become a primary communication channel among people to report either to public or to emergency responders (ERs). ERs, who are from various emergency response organizations (EROs), usually consider to gain awareness of the situation in order to respond to occurred disaster. However, with the occurrence of the disaster, within minutes, the social media platforms are flooded with various kinds of data which become overwhelmed for ERs with big data. Fu…
Antecedents and consequences of problematic smartphone use: A systematic literature review of an emerging research area
2021
Abstract This article provides a systematic review of existing research on problematic smartphone use (PSU) to guide other researchers in search of relevant studies, and to propose areas for future research. In total, 293 studies were analyzed leading to the development of an overview model in the field of PSU, presenting findings on demographic factors, explanations for smartphone use and why this use becomes problematic, consequences of PSU, and how such use can be corrected. In addition, we considered in which contexts, with which methods, and with which theoretical lenses this stream of research has been studied to date. Smartphone use is most often explained by the smartphone design, a…
When care situations evoke difficult emotions in nursing staff members: an ethnographic study in two Norwegian nursing homes
2015
Background Caring practice in nursing homes is a complex topic, especially the challenges of meeting the basic needs of residents when their behaviour evokes difficult emotions. Cognitive and physical changes related to aging and disability can contribute to behaviours considered to be unacceptable. For example, resident behaviours such as spitting, making a mess with food or grinding teeth are behaviours that most people do not want to see, hear or experience. The aim of this study was to gain a deeper understanding of how nursing home staff members deal with such behaviours in care situations. Methods This article draws on ethnographic data to describe how nursing home staff members manag…
Sharing economy and dynamic pricing: Is the impact of Airbnb on the hotel industry time-dependent?
2021
Abstract Prior literature has reported significant price and revenue reductions in the hotel industry due to the emergence of Airbnb. Other studies have documented that hotels' price reactions to the penetration of Airbnb depend on their service level, e.g., low/medium-end versus high end. Relying on a large sample from the Italian market, we contribute by showing that the effect of Airbnb on hotels' price decisions does not only depend on incumbents’ quality level, but also on the difference between booking and check-in time. That is, the effect of the penetration of Airbnb on hotels' dynamic price decisions varies over time depending on the core segment hotels target.
Exploring the role of the sharing economy in disasters management
2020
Abstract Improvements in information and communications technologies (ICTs) have facilitated the inclusion of the sharing economy (SE) in societies more than ever. In the aftermath of recent disasters, the SE played significant roles to help the affected people and support official responders. However, the literature has not effectively explored these roles, and thus, no framework can support the systematic inclusion of the SE in disasters management. This paper aims to address the gap through a two-stage exploratory research approach. First, we conduct a systematic literature review to identify the extent to which the SE is taken into consideration in disasters. After that, we investigate …
