Abstract

Purpose

Ensuring quality is one of the most significant challenges in microtask crowdsourcing tasks. Aggregation of the collected data from the crowd is one of the important steps to infer the correct answer, but the existing study seems to be limited to the single-step task. This study aims to look at multiple-step classification tasks and understand aggregation in such cases; hence, it is useful for assessing the classification quality.

Design/methodology/approach

The authors present a model to capture the information of the workflow, questions and answers for both single- and multiple-question classification tasks. They propose an adapted approach on top of the classic approach so that the model can handle tasks with several multiple-choice questions in general instead of a specific domain or any specific hierarchical classifications. They evaluate their approach with three representative tasks from existing citizen science projects in which they have the gold standard created by experts.

Findings

The results show that the approach can provide significant improvements to the overall classification accuracy. The authors’ analysis also demonstrates that all algorithms can achieve higher accuracy for the volunteer- versus paid-generated data sets for the same task. Furthermore, the authors observed interesting patterns in the relationship between the performance of different algorithms and workflow-specific factors including the number of steps and the number of available options in each step.

Originality/value

Due to the nature of crowdsourcing, aggregating the collected data is an important process to understand the quality of crowdsourcing results. Different inference algorithms have been studied for simple microtasks consisting of single questions with two or more answers. However, as classification tasks typically contain many questions, the proposed method can be applied to a wide range of tasks including both single- and multiple-question classification tasks.

Abstract

Purpose

The purpose of this paper is to focus on ethical and judicial themes related to technology and the older adults.

Design/methodology/approach

Different consecutive phases in technology design and allocation will be discussed from a range of perspectives.

Findings

Longevity is one of the greatest achievements of contemporary science and a result of development of social relations. Currently, various non-communicable diseases affect older adults and impose the greatest burden on global health. There is a great emphasis across Europe on caring for the older person in their own homes. Technology has a mediating role in determining the possibilities for good quality of life (QOL). The concept of assisting the older adult through the use of technology so as to access healthcare services has enormous potential. Although the potential of technology in healthcare is widely recognised, technology use can have its downsides. Professionals need to be aware of the risks, namely, those related to the privacy of the older person, which may accompany technology use.

Research limitations/implications

By 2050, there will be more people aged over 65 than there are children. This phenomenon of global ageing constitutes a massive challenge in the area of health protection.

Practical implications

Professionals need to be aware of the risks, for example, related to the privacy of the older person, that may accompany technology use.

Social implications

There is a great emphasis across Europe on caring for the older person in their own homes. Technology has a mediating role in determining the possibilities for QOL.

Originality/value

The concept of assisting the older adult through the use of technology to avail of healthcare has enormous potential. Assistive technology, social media use and augmentative and alternative communication can have a positive effect on the QOL of older people, as long as they are supported enough in use of these technologies. However, ethical and juridical considerations are at stake as well.

Abstract

Purpose

This micro-level study unpacks the recruitment and retention of international professionals to small and medium-sized enterprises (SMEs). The study highlights the influence of the founders' international experience when applying organisational-level (meso) policies and practices. With their insider experience as skilled migrants, we share how the founders in each of the SMEs mobilised career capital into human resource management (HRM) strategies.

Design/methodology/approach

Combining literature on SMEs and skilled migrants' careers, we draw upon intelligent career theory to illuminate the recruitment and retention of self-initiated expatriates and skilled migrants in SMEs. With three SME case studies as samples–one micro, one small and one medium-sized organisation in Ireland–we consider the influence of the founders' international experience in the design and application of formal and informal HRM strategies (at the organisational level) that are operationalised to recruit and retain international talent to/in these organisations.

Findings

The HRM practices in the three SME cases in this paper, each run by migrant founders, vary from formalised (for our medium-sized organisation), semi-formalised (for our small-sized organisation) to ad hoc and tailor-made (for our micro-sized organisation). These particular SMEs were often more receptive to hiring other migrants. The important role of the three SME case studies' skilled migrant founders and their own international career experiences was apparent in the particular HRM approaches they adopted. The relevance of intelligent career theory when applying micro-level findings at the meso-organisational level is shown.

Originality/value

The paper presents how the international experience of founder–managers, in turn, impacts on the HRM practices and policies that are implemented to recruit and retain international employees. The study highlights how both organisation size and founder-manager international experience influence the degree of customisation of HRM practices and policies in SMEs, specifically pertaining to the recruitment and retention of self-initiated expatriates and skilled migrant employees. The heterogeneity within the sub-categories encompassed under the umbrella label of SME is emphasised; validating our case study approach, where nuance and detail of the specific organisation can be shared.

Abstract

Purpose

The purpose of this study is to explore the impact of the Covid-19 crisis at the level of individual information behavior among citizens from the German-speaking countries, Austria, Germany and Switzerland.

Design/methodology/approach

An online survey was conducted among 308 participants gathered through convenience sampling in April and May 2020, focusing on how citizens changed their mix and usage intensity of information sources and according to which criteria they chose them during the Covid-19 crisis. A Wilcoxon signed-rank test was used for testing central tendencies. Effect sizes were considered to support the interpretation.

Findings

The results show first that the Covid-19 crisis has led to an increased demand for reliable information. This goes alongside a significant increased use of public broadcasting, newspapers and information provided by public organizations. Second, the majority (84%) of the participants reported being satisfied with the information supply during the Covid-19 crisis. Participants who were less satisfied with the information supply used reliable sources significantly less frequently, specifically public television, national newspapers and information provided by public organizations. Third, the amount of Covid-19-related information led some participants to a feeling of information overload, which resulted in a reduction of information seeking and media use.

Originality/value

This paper is one of the first to analyze changes of information behavior patterns of individuals during crises in the current information environment, considering the diversity of resources used by individuals.

Abstract

Purpose

In this article, the author discusses works from the French Documentation Movement in the 1940s and 1950s with regard to how it formulates bibliographic classification systems as documents. Significant writings by Suzanne Briet, Éric de Grolier and Robert Pagès are analyzed in the light of current document-theoretical concepts and discussions.

Design/methodology/approach

Conceptual analysis.

Findings

The French Documentation Movement provided a rich intellectual environment in the late 1940s and early 1950s, resulting in original works on documents and the ways these may be represented bibliographically. These works display a variety of approaches from object-oriented description to notational concept-synthesis, and definitions of classification systems as isomorph documents at the center of politically informed critique of modern society.

Originality/value

The article brings together historical and conceptual elements in the analysis which have not previously been combined in Library and Information Science literature. In the analysis, the article discusses significant contributions to classification and document theory that hitherto have eluded attention from the wider international Library and Information Science research community. Through this, the article contributes to the currently ongoing conceptual discussion on documents and documentality.

Abstract

Purpose

The purpose of the paper is to examine how media synchronicity facilitates the emergence of social exchange (i.e. trust and reciprocity) in organizations’ information and communication technology (ICT)-mediated interactions. A model of media synchronicity in organizational social exchange (MSiOSE) is proposed.

Design/methodology/approach

The paper has a design and review approach. The theoretical analysis is based on social exchange theory (SET) and media synchronicity theory (MST).

Findings

The authors propose that, in general, social exchange benefits from both asynchronous and synchronous communication processes. However, media synchronicity has different boundary conditions (i.e. pros and cons) in relation to the emergence of social exchange, determined in accordance with the mutually interacting patterns of trust and reciprocity predicted by SET. The authors provide testable theoretical propositions to support the analysis.

Originality/value

Social exchange is a critical business factor for organizations due to its well-known positive outcomes, such as the strengthening of social ties. The need for successful social exchange in remote work conditions is particularly emphasized. However, with regard to the communication and behavioral patterns that lead to social exchange via ICT, the theoretical understanding is limited. The study reveals previously unmapped heuristics between social exchange and physical media capabilities. Thus, the study's propositions can be used to study and analyze social exchange in the ever-changing media landscape. As a practical contribution, the study helps organizations to improve their communication strategies and use of ICT.

Abstract

The world over is becoming urbanized, and people are migrating to cities in large numbers in search of opportunities. The increased urbanization has posed challenges such as congestion, rising crime, and growing urban poverty. The governments respond by providing amenities such as schools, hospitals, and housing to meet to increase in demand for these facilities. However, there is a need for the provision of facilities that meets the expectations of the people, particularly on the proximity of amenities and bundles of utility-bearing housing characteristics. In an attempt to address the challenge mentioned, the study estimated the hedonic characteristics influencing the willingness to accept and willingness to pay for housing facilities in the Eastern Cape Province, South Africa. Using a multiple linear regression model and artificial neural network, the study found out that properties with a bathroom, garage and large floor size have a higher value compared to properties without these facilities.When making decisions to acquire a property, buyers consider the availability of discounts and the prevailing property price. Overall, willingness to pay and accept decisions are mainly determined by location and the price at which homogeneous neighborhood properties were sold. Therefore, the study recommends that urban town planners and other housing authorities prioritize the construction of properties with larger floor areas, parking bays, and bathrooms using a cost-effective mechanism that makes the properties affordable to residents.

Abstract

People are starting to doubt business recovery in office market after global financial crisis in 2008. And most institutional and individual portfolios are undiversified in real estate : incurring enormous transaction costs than other financial products. Especially office market has more risks than other real estate market for high transaction costs and many related industries. Although this stuff can lead to increase the risk of investment in office market, nor are there markets that would allow individuals and institutions to hedge their risks. The establishment of office price index future and option markets is likely to hedge away large risk in office market, and provides lowering transaction costs for trading in real estate. We estimate Office Price Index using S&P/Case-Shiller repeat sale estimator which is proposed by Robert. J. Shiller in 1991. The estimator is a sort of Feasible Generalized Two Stage Least Squares, which compute Value weighted Arithmetic Price Index.

Abstract

Purpose

The purpose of this paper is to examine the awareness of intellectual disabilities (ID) amongst professionals in the criminal justice system (CJS) and their knowledge of those persons, either as victims, witnesses, suspects, accused or defendants.

Design/methodology/approach

A survey of the professionals in the CJS (n=388), combined with a series of focus group interviews with experienced professionals (n=20), was conducted.

Findings

One out of three respondents (police, district attorneys and judges) reported that they have regular contact with suspects who have an ID. Differences in knowledge of ID amongst professionals in the CJS can explain awareness and detection of persons with ID.

Research limitations/implications

Non-responders may represent professionals with no knowledge or less interest in these issues.

Originality/value

Reflections on ID have not previously been studied in the Norwegian CJS. The findings serve as a basis and status quo for further research.

Abstract

Purpose

The purpose of this paper is to present a model depicting the relationship between the behavioral intention of tourists in the conditions prevailing during a pandemic and other variables.

Design/methodology/approach

In constructing the research procedure, two measurements of tourist behavioral intention were taken into account, which were taken far apart in time. In verifying the developed model, the results of surveys of 1,615 people carried out in June 2021 and 917 people carried out in December 2021 were considered.

Findings

As a result of the habituation process, tourists show greater acceptance of the restrictions.

Practical implications

Information on the basis of which companies make management decisions plays a significant role in the creation of company value. In the tourism sector, the information concerns primarily consumer behavior.

Originality/value

Changes over time in risk perception, health protection motivation, and reactance due to perceived pandemic-related restrictions were taken into account in the context of behavioral intention towards tourism.
