Abstract
Purpose
This paper evaluates the precision of four metasearch engines (MSEs) – DuckDuckGo, Dogpile, Metacrawler and Startpage, to determine which metasearch engine exhibits the highest level of precision and to identify the metasearch engine that is most likely to return the most relevant search results.
Design/methodology/approach
The research is divided into two parts: the first phase involves four queries categorized into two segments (4-Q-2-S), while the second phase includes six queries divided into three segments (6-Q-3-S). These queries vary in complexity, falling into three types: simple, phrase and complex. The precision, average precision and the presence of duplicates across all the evaluated metasearch engines are determined.
Findings
The study clearly demonstrated that Startpage returned the most relevant results and achieved the highest precision (0.98) among the four MSEs. Conversely, DuckDuckGo exhibited consistent performance across both phases of the study.
Research limitations/implications
The study only evaluated four metasearch engines, which may not be representative of all available metasearch engines. Additionally, a limited number of queries were used, which may not be sufficient to generalize the findings to all types of queries.
Practical implications
The findings of this study can be valuable for accreditation agencies in managing duplicates, improving their search capabilities and obtaining more relevant and precise results. These findings can also assist users in selecting the best metasearch engine based on precision rather than interface.
Originality/value
The study is the first of its kind which evaluates the four metasearch engines. No similar study has been conducted in the past to measure the performance of metasearch engines.

Abstract
Exploring subjective experiences of people living with dementia through qualitative research has become increasingly common in recent decades. Nonetheless, researchers have shared a number of ethical challenges in involving people living with dementia in research. A concept that has been influential in discussions about ethics within the field of dementia care, in particular, is person-centredness. A person-centred approach reflects values of respect for personhood and the rights of a person and of building mutual trust and understanding. This chapter presents my experience of adopting person-centred ethical practices in a sensory ethnographic study involving older adults living with dementia. I highlight person-centred ethical considerations at the design stage of my study and occasions during the conduct of my research when research methods and processes were adapted to further meet the needs of the participants. A person-centred approach required that I continually assessed the need to make ethical decisions in every aspect of the research process throughout its duration. Building and drawing on positive researcher–participant relationships to inform those decisions and an adaptable research design allowing research practices to be adapted in situ were therefore essential.

Abstract
Purpose
Variations in customer expectations pose a challenge to service quality improvement in the airline industry. Understanding airline customers' expectations and satisfaction help service providers improve their offerings. The extant literature examines airline passengers' expectations in isolation, neglecting the overall impact of online reviews on service quality improvement. This paper systematically evaluates the airline industry's passengers' expectations and satisfaction using expectation confirmation theory (ECT) and the SERVQUAL framework. The paper analyzes online reviews to examine the relationship between airline service quality attributes and passengers' satisfaction.
Design/methodology/approach
The SERVQUAL framework was employed to examine the effects of customer culture, the reason for traveling, and seat type on customer's expectations and satisfaction across a large sample of airline customers.
Findings
A total of 17,726 observations were gathered from the Skytrax review website. The lowest satisfaction ratings were from passengers from the USA, Canada and India. Factors that affect perceived service performance include customer service, delays and baggage management. Empathy and reliability have the biggest impact on the perceived satisfaction of passengers.
Research limitations/implications
This research increases understanding of the consumer expectations through analysis of passengers' online reviews. Results are limited to a small sample of airline industries.
Practical implications
This study provides airlines with valuable information to improve customer service by analyzing online reviews.
Social implications
This study provides the opportunity for airline customers to gain better services when airline companies utilize the findings.
Originality/value
This paper offers insights into passengers' expectations and their perceived value for money in relation to seat types. Previous studies have not investigated value for money as a construct for passengers' expectations and satisfaction relative to service quality dimensions. This paper addresses this need.
