Retirement timing in a future welfare state: a Finnish Delphi study
Authors: Niemi Tuukka , Komp Kathrin 
Published: August 2018

Purpose
European welfare states, including Finland, have recently introduced reforms that aim to delay the average timing of retirement. The degree of success of these reforms will depend on future institutional and societal developments that influence retirement timing. The purpose of this paper is to identify such scenarios in the Finnish context.

Design/methodology/approach
The study employs the Delphi method by interviewing anonymous experts from a variety of relevant organisations and fields in Finland, then sending them a scaled on-line questionnaire from the initial findings to elicit views on the likelihood of different scenarios influencing retirement timing over the next 20 years.

Findings
While the experts perceived that a raised state pension age and a removal of early retirement options will inevitably delay retirement on average, multiple scenarios were believe to hinder this trend. These included domestic elderly care becoming more common, technology-induced restructuring of labour markets and shortening working weeks, all of which were associated with widening socioeconomic inequalities in retirement timing. The predicted inequalities were attributed to a polarisation concerning older workers’ abilities to extend their careers and to plan their retirement. The planned mass privatisation of health and social services in Finland was perceived to accelerate this outcome.

Practical implications
The study suggests that a significant policy challenge in face of upcoming societal trends is to make delayed retirement a more equally viable option.

Originality/value
This paper demonstrates the usefulness of scenario building for anticipating possible developments that may influence the success of policies aimed at delaying retirement.
Revealing the effect of acculturation process on e-commerce acceptance
Authors: Lacka Ewelina , Yip Nick K.T. 
Published: August 2018

Purpose
The popularity of e-commerce has increased significantly over recent years. However, this growth is not shared by all European Union states. One reason for this discrepancy is culture which impacts on e-commerce acceptance. The purpose of this paper is to reveal the effect of acculturation process on e-commerce acceptance.

Design/methodology/approach
Structural equation modelling is employed to test three research models: technology acceptance model, theory of planned behaviour model and motivational model.

Findings
The findings show that attitudes towards e-commerce change in relation to the perception of control and the influence of subjective norms, which impact intentions to use e-commerce before movement to a host country’s culture. However, its effect diminishes after the exposure to the influence of a host culture.

Originality/value
This is the first study to demonstrate the existence of the effect of acculturation process on mingling and migrating consumers and their changing attitudes towards e-commerce acceptance.
Framework for continuous agile technology roadmap updating
Authors: Carlos Rafael , Amaral Daniel C. , Caetano Mauro 
Published: August 2018

Purpose
Roadmapping has been used as an approach to support market, product and technology-integrated planning, resulting in a document commonly known as a roadmap. Despite the gains made in relation to the technique, recent studies indicate that most users leave or have difficulties in sustaining the process (i.e. maintaining the updated roadmaps). This paper aims to present a framework for continuous roadmap updating that incorporates principles from agile management fields.

Design/methodology/approach
The framework was developed through action research in a manufacturing firm in the construction industry.

Findings
The results demonstrate a positive impact on the degree of continuous information monitoring, roadmap credibility and use of the roadmap during innovation strategy decisions.

Originality/value
The key contribution of this framework is the demonstration of a new strategy for carrying out the maps in which information is internalized by the organization itself, using agile teams, without commissioned specialists and as part of the work standards.
Contextual and individual characteristics effects on students’ corruption perception and behaviours in higher education
Authors: Tomo Andrea , Todisco Lucio , Mangia Gianluigi 
Published: August 2018

Purpose
The purpose of this paper is to provide an analysis of the effects that the perceived corruption has on students’ behaviours. In more detail, the analysis will explain how the individual and contextual variables influence students’ behaviours and corruption perception.

Design/methodology/approach
The authors employed a structured questionnaire administered to 200 Italian students attending Bachelor and Master Degrees courses, based on a theoretical background that considers corruption in higher education as the result of the interplay between the various actors and institutions in the field.

Findings
Findings have both interesting academic and practical implications, since the study advances the literature on corruption in higher education and also advances a framework explaining how contextual and individual characteristics influence students’ behaviours and corruption perception.

Originality/value
The study presents manifold interesting implications both for academics, practitioners and policy-makers on the impact that students’ corruption perception has on the whole higher education system.
The surprising lack of connection between social networks and the enterprise success of ultra-religious female micro-entrepreneurs
Authors: Monnickendam-Givon Yisca , Schwartz Dafna , Gidron Benjamin 
Published: August 2018

Purpose
The utilization of social networks is known to have an impact on micro-enterprise success. This study aims to examine the contribution of social networks in acquiring resources and their role in the enterprise’s success.

Design/methodology/approach
A business’s success is influenced by its network structure and the network’s resources. The authors examine whether unique religious-cultural characteristics affect the social networks contribution to a business’s success. This model examines the network utilization of women entrepreneurs who own micro-enterprises in ultra-religious groups. The sample consists of 123 surveys completed by Jewish ultra-Orthodox women entrepreneurs in Israel. Data collection was conducted between February and June 2013. The authors used a snowball sampling approach where interviewees were asked to refer us to other entrepreneurs. In the hour-long interview, a questionnaire was used with open and closed questions.

Findings
Findings indicate that strong personal ties provide a micro-enterprise with social legitimacy, emotional support and assistance in the management and operation of daily activities. However, contrary to the existing literature, network utilization did not contribute to enterprise success. That is, in religious communities in particular, social networks enable the existence of businesses, but do not contribute to their success.

Practical implications
The practical implications of this paper are the mapping of the social network resources used by the business owner, such as financial consultations or professional assistance, as well as distinguishing between strong and weak ties, which reflect the intensity of the contact for better use of the social network by the entrepreneurs.

Originality/value
This study examined social networks’ contribution to the acquisition of resources, as well as the part they play in the success of ultra-orthodox women micro-entrepreneurs and perhaps other religious and minorities groups.
The role of cooperative alliances in internationalization strategy
Authors: Morais Flávio , Franco Mário 
Published: August 2018

Purpose
From the network approach, the purpose of this paper is to provide empirical evidence about the role of international cooperative alliances (CAs) in the decision of small- and medium-sized enterprises (SMEs) to internationalize and remain in the external market.

Design/methodology/approach
To fulfill the proposed objective, qualitative research was carried out through analyzing two SMEs (case studies) in the Portuguese textile sector. Data collection was based on structured interviews, direct observation and some documental analysis.

Findings
The results show that the analyzed SMEs internationalized immediately after their creation, with this decision not being influenced by CAs but rather by the founder’s role and above all by a saturated domestic market.

Practical implications
Alliances are determinant in subsequent developments in the foreign market, allowing SMEs to reach new markets, increase their market share and consolidate their name in the international market. Thus, managers/entrepreneurs should adopt strategies that stimulate the firm’s expansion in the external market, prioritizing the formation of CAs with international partners.

Originality/value
This study suggests that none of the dominant models can exclusively explain the internationalization process of the studied SMEs. Therefore, this research has implications for the recent stream of literature that argues for a holistic view of internationalization models, considering the arguments of all models instead of only one.
Impact of mentoring on practicing engineers: a meta-synthesis
Authors: Wong Silky S.K. , Cross Jennifer A. , Mueller Phillip S. 
Published: August 2018

Purpose
This paper aims to present a literature review to examine the career development outcomes on practicing engineering novices who are being mentored at work, and factors of mentoring that contribute to those career development outcomes.

Design/methodology/approach
Through a meta-synthesis, the research premises and findings of 12 articles identified through a systematic search of nine databases were examined and synthesized, to identify the most common career development outcomes and the most influential factors contributing to these outcomes.

Findings
The most common contributing factors were found to be job characteristics, career development mentoring support, psychosocial mentoring support and mentoring methods. The most frequent career outcomes were career satisfaction and promotion.

Research limitations/implications
The sample consisted of only 12 articles; however, according to the guidelines of meta-synthesis and Critical Appraisal Skills Program (CASP), the sample size was ideal. Further, articles were all of high or very high quality, and, in all studies, multiple contributing factors were measured to investigate the relationships among those factors and career outcomes. The factors and outcomes can be considered by researchers as study variables in future studies.

Practical implications
Organizations and practitioners can use factors that influence mentoring outcomes and the mentoring outcomes found in this study to develop more effective mentoring programs.

Originality/value
To the authors’ knowledge, this is the first systematic review of prior research regarding mentoring for practicing engineers. This paper allows researchers and practitioners to identify key findings and trends in past works, recognize research gaps and propose future research directions.
Social learning constructs and employee learning performance in informal Web-based learning environments
Authors: Lee HyunKyung , Lee MyungGeun 
Published: August 2018

Purpose
The purpose of this paper is to investigate the relationship between social learning constructs and perceived learning performance in corporate informal Web-based learning environments. The study aims at providing significant implications for corporate educators who have worked on designing social learning environments in the workplace.

Design/methodology/approach
To identify the casual relationship of the proposed research model, data collected from 523 South Koreans who were corporate employees and social media users were analyzed using structural equation modeling.

Findings
The results indicate that self-motivation, learning community and social media usage were significantly related to perceived learning performance. In addition, social media usage mediated the relationship between the other social learning constructs and the learning performance.

Originality/value
Given that corporate personnel typically gain job-related knowledge and skills through social learning, corporate educators need to provide learners with social learning environments that are conducive to self-motivation and learning community. Social media, when used as a learning tool, might not sufficiently improve learning performance without the help of other social learning constructs. Findings shed light on which social learning constructs are essential to effective social learning environment design in the workplace.
Understanding intellectual capital disclosure in online media Big Data
Authors: Ndou Valentina , Secundo Giustina , Dumay John , Gjevori Elvin 
Published: August 2018

Purpose
Intellectual capital disclosure (ICD) in universities is gaining increasing attention, especially through the adoption of innovative technologies. Online media, as a relevant source of Big Data, is shifting ICD. The purpose of this paper is to explore how Big Data generated through online media, such as websites and platforms like Facebook, can be used as rich sources of data and viable disclosure channels for ICD in a university.

Design/methodology/approach
This is an exploratory case study, following the methodology in Yin (2014), that examines how online media data contributes to closing the ICD gap. The IC disclosed through different online media channels by a private university in Albania is analysed using Secundo et al.’s (2016) collective intelligence framework. The online data sources include the university’s website, Facebook page, periodic reports and statements outlining future goals.

Findings
What the authors discover in this research is that IC is an important part of how universities operate, and IC is communicated through social media, although unintentionally. However, this only serves to highlight the importance of IC, and if researchers want to discover IC and understand how it works in an organisation, they need to include social media and a prime resource for developing that understanding.

Research limitations/implications
Most importantly, the findings add to a growing consensus that ICD researchers, and researchers in other management and accounting disciplines, who traditionally rely on annual corporate social responsibility and other periodic reports, they need to change their medium of analysis because these reports no longer can be relied on to understand IC and its impact on an organisation.

Originality/value
Online media tools and the advent of Big Data have created new opportunities for universities to disclose their IC information to stakeholders in a timely manner and to gain relevant insights into their impact on the society. The originality of the paper resides in the contribution of Big Data to the ICD research stream.

Authors: Jalali Farahani Gholamreza , Hosnavi Reza , Ataee Mohamad Hasan , Ghanbary Nasab Ali , Ataee Mohammad Ali 
Published: August 2018

PurposeThe purpose of this paper is to determine and prioritize man-made threats that have the probability of occurring in civilian airports, as an important part of critical infrastructures in each country.Design/methodology/approachThe paper is practical-developmental in terms of research type and its approach is descriptive. Desktop research methods and interviews (qualitative) have been used in identifying deliberate man-made threats that are faced by the civilian airports. Moreover, a questionnaire (quantitative) has been utilized to assess the civilian airports’ assets that are targets likely to be threatened and assess threats by determining and prioritizing.FindingsThe results of the paper show that the main threat faced by civilian airports is “Air and missile strikes.” An additional 15 threats endangering civilian airports that have been extracted and presented through integrating specialized literature were prioritized in the main components of civilian airports. This prioritization has been performed on the basis of the following five indicators: “Damage Severity,” “Threat Precedent,” “Target Attractiveness,” “Negative Consequences for the Enemy” and “Enemy Ability.”Originality/valueThis paper is extracted from master’s thesis that identifies and assesses the threats to civil airport, and prioritizes them, and the results were confirmed by the experts.
Self-emulsified waterborne epoxy hardener without acid neutralizers and its emulsifying and curing properties
Authors: Yin Hao , Wan Yun , Zhou Jinjun , Sun Dewen , Li Bo , Ran Qianping 
Published: August 2018

Purpose
The purpose of this study is to prepare a new self-emulsified waterborne epoxy hardener which can emulsify the liquid epoxy resin in aqueous media without addition of acid neutralizers.

Design/methodology/approach
Two synthetic steps were adopted to prepare novel self-emulsified amine-epoxy adduct type hardener composition based on the reaction of a commercially available polyetheramine, bisphenol A epoxy resin and triethylene tetramine. The different factors affecting the synthesis of the waterborne epoxy hardener were explored by emulsifying and curing properties. The process and products were analyzed and confirmed by FIRT.

Findings
Compared to an introduction of polyether as a hydrophilic segment in previous literature, whose reaction required Lewis acid catalysts and strict control of the presence of water, the introduction of polyetheramine to obtain a novel self-emulsified waterborne epoxy hardener were concise and convenient by mere two amine-epoxy addition steps in this research. Moreover, the final product offered good film formation with a practical value of mechanical properties, glass transition temperature and water-resistant property.

Practical implications
The self-emulsified waterborne epoxy hardener can be used to prepare water-resistant waterborne coatings from liquid epoxy resins while also providing the option of zero VOC formulations.

Originality/value
Introduction of hydrophilic polyether amine to prepare self-emulsified waterborne epoxy hardener without acid neutralizers has not been systematically studied previously.
Tensile behavior of aloe vera fiber reinforced epoxy and polyester resin matrix composites
Authors: Jenarthanan M.P. , Marappan Karthikeyan 
Published: August 2018

Purpose
This paper aims to investigate the tensile behavior of epoxy and polyester matrix composites reinforced with continuous and aligned aloe vera fibers.

Design/methodology/approach
Composites with different volume fractions (30, 40 and 50 Vol. %) were fabricated by laying the fibers in a steel mould and pouring liquid resin, either DEGEBA/TETA epoxy or methyl-ethyl ketone hardened orthophthalic polyester, under pressure of 3 MPa. The specimens were cured for 24 h at room temperature and then tested in a universal Instron testing machine, model 5582, at 298 K (25°C).

Findings
The fracture surface was analyzed by scanning electron microscopy (SEM) under an acceleration voltage of 15 kV. SEM fractography revealed a poor adhesion between both the epoxy and polyester matrices with the aloe vera fiber. The results showed that in both cases the introduction of aloe vera fibers had a minor effect on the matrix reinforcement.

Originality/value
Investigation and comparison of tensile behavior of epoxy and polyester matrix composites reinforced with continuous and aligned aloe vera fibers have not been attempted so far.
Environmental safety: Air pollution while using MIRUS™ for short‐term sedation in the ICU
Authors: Herzog‐Niescery Jennifer , Vogelsang Heike , Gude Philipp , Seipp Hans‐Martin , Uhl Waldemar , Weber Thomas P. , Bellgardt Martin 
Published: August 2018

BackgroundMIRUS™ is a device for target‐controlled inhalational sedation in the ICU in combination with use of isoflurane, or sevoflurane, or desflurane. The feasibility of this device has recently been proven; however, ICU staff exposure may restrict its application. We investigated ICU ambient room pollution during daily work to estimate ICU personnel exposure while using MIRUS™.MethodsThis observational study assessed pollution levels around 15 adult surgical patients who received volatile anaesthetics‐based sedation for a median of 11 hours. Measurements were performed by photoacoustic gas monitoring in real‐time at different positions near the patient and in the personnel's breathing zone. Additionally, the impact of the Clean Air™ open reservoir scavenging system on volatile agent pollution was evaluated.ResultsBaseline concentrations [ppm] during intervention and rest periods were isoflurane = 0.58 ± 0.49, = 5.72; sevoflurane = 0.22 ± 0.20, = 7.93; and desflurane = 0.65 ± 0.57, = 6.65. Refilling MIRUS™ with liquid anaesthetic yielded gas concentrations of = 2.18 ± 1.48 ppm and = 13.03 ± 9.37 ppm in the personnel's breathing zone. Air pollution in the patient's room was approximately five times higher without a scavenging system.ConclusionAmbient room pollution was minimal in most cases, and the measured values were within or below the recommended exposure limits. Caution should be taken during refilling of the MIRUS™ system, as this was accompanied by higher pollution levels. The combined use of air‐conditioning and gas scavenging systems is strongly recommended.

AbstractRemodeling of the extracellular matrix is a key component of the metabolic adaptations of adipose tissue in response to dietary and physiological challenges. Disruption of its integrity is a well‐known aspect of adipose tissue dysfunction, for instance, during aging and obesity. Adipocyte regeneration from a tissue‐resident pool of mesenchymal stem cells is part of normal tissue homeostasis. Among the pathophysiological consequences of adipogenic stem cell aging, characteristic changes in the secretory phenotype, which includes matrix‐modifying proteins, have been described. Here, we show that the expression of the matricellular protein periostin, a component of the extracellular matrix produced and secreted by adipose tissue‐resident interstitial cells, is markedly decreased in aged brown and white adipose tissue depots. Using a mouse model, we demonstrate that the adaptation of adipose tissue to adrenergic stimulation and high‐fat diet feeding is impaired in animals with systemic ablation of the gene encoding for periostin. Our data suggest that loss of periostin attenuates lipid metabolism in adipose tissue, thus recapitulating one aspect of age‐related metabolic dysfunction. In human white adipose tissue, periostin expression showed an unexpected positive correlation with age of study participants. This correlation, however, was no longer evident after adjusting for BMI or plasma lipid and liver function biomarkers. These findings taken together suggest that age‐related alterations of the adipose tissue extracellular matrix may contribute to the development of metabolic disease by negatively affecting nutrient homeostasis.
