The proposed metamaterial absorber (MMA) has the following advantages: first, the structure of the MMA consists of one planar metallic resonator, which presents a new design approach to obtain a multiband absorption response, rather than using multiple unit-cells in the one large unit cell or stacking different layers. Second, the simultaneous realization of triple-band and dual-band absorption (or bi-functional absorption) at five different frequencies can integrate the respective advantages of the triple functions of the triple-band MMA and double-band MMA, and therefore, the bi-functional MMA will find more application prospects than multiple-functional devices of triple-band and dual-band. Third, the authors simulated the three combinations of MMA here, which is indium tin oxide (ITO)-Polyimide-ITO, ITO-Teflon-ITO and ITO-polyethylene terephthalate (PET)-ITO for the same planar structure and achieve a high absorption rate. Finally, the proposed structure is polarization and angle independent in nature.

This absorption device consists of the top circular resonator, the middle insulating SiO₂ medium layer and the bottom metallic copper ground plane placed on a substrate. The conductivity of the copper metal is s = 5.8 × 10⁷ s/m. As the transmission of the MMA structure is zero, the substrate materials can be selected randomly. Totally four combinations of terahertz MMA are designed and simulated here which are ITO- SiO₂ –ITO, ITO-Polyimide-ITO, ITO-Teflon-ITO and ITO- PET-ITO for the same planar structure.

The literature on information technology outsourcing (ITO) prioritises monetary considerations and overlooks human aspects. This qualitative study adopts a contextualised approach to address a research gap in understanding agency workers’ intent to stay in the ITO sector.

In contrast to previous studies that focus on intra-organisational factors and use quantitative designs, this study takes a qualitative approach. It analyses data from 85 in-depth interviews with agency workers in the Chinese ITO supply chain and project managers of supplier and client firms.

The study constructs an integrated framework covering 15 factors at three levels and shows how they interact to influence Chinese agency workers’ intent to stay in the ITO supply chain. Variations in outsourcing management styles and practices among U.S., Japanese and Chinese client firms are presented to enrich the understanding of outsourcing dynamics in a global context.

This study contributes to the ITO literature by providing new insights into the retention of highly skilled agency workers and deepening the contextual understanding of this issue, throwing light on the human aspects often overshadowed by monetary considerations.

This paper aims to explain how small- and medium-sized firms (SMEs) create information technology (IT) business value through blended IT outsourcing (ITO). The explanatory framework it proposes enables SMEs to replicate IT capability outcomes (i.e. enhance their economic, strategic and technological competences, namely, ITO success) by endorsing an ITO strategy catalyzed by IT vendor integration.

This study uses covariance-based structural equation modeling to test the proposed research model. Data are collected from 251 knowledge-intensive business SMEs located in Science and Technology Parks in Spain.

The results demonstrate empirically that SMEs can replicate IT capability benefits (i.e. enhance their non-IT competences) through blended ITO in which IT, conceptualized as a transversal supporting activity, is outsourced to an IT vendor while the value creation process remains with the buyer. The integration (i.e. process integration and information sharing) of an IT-proficient vendor catalyzes ITO success. More specifically, the results show that, although process integration is not directly related to competence enhancement, fosters information sharing, which directly facilitates ITO success. The results also show that IT vendor proficiency accounts for ex ante trust.

Managers should think of transformational ITO as a strategy to enhance firm competences. For blended ITO strategies to succeed, managers must have a comprehensive understanding of the business they run, as it is important to create conditions that foster inter-firm information sharing. To achieve these conditions, managers should take special care in selecting boundary spanners, who are the pivotal links in competence enhancement.

While most research focuses on ongoing trust (i.e. trust develops as ITO evolves), this study focuses on initial (i.e. ex ante) trust and analyzes IT vendor proficiency (expert, experienced and reputed) to examine trust as an antecedent of ITO. This study also draws on previous conceptualizations of vendor integration to develop and analyze a two-step integration model to explain how IT vendor integration (i.e. process integration and information sharing) catalyzes enhancement of the buyer’s non-IT competences. This study focuses on SMEs, which are often neglected in ITO studies.

A multitude of factors influence the information technology outsourcing (ITO) decision. Organizations must systematically evaluate these factors prior to making the ITO decision. The purpose of this paper is to provide an in-depth analysis toward understanding the critical factors in affecting ITO decision in the context of e-banking services.

The effect of technological, organizational, and environmental attributes on e-banking services outsourcing decision were investigated in this paper. The study was carried out using the quantitative research methodology based on a survey of 23 banks. The partial least squares technique was utilized as the method of data analysis.

The results of the data analysis illustrated that nine out of 11 assumed factors (i.e. perceived complexity, perceived cost, service observability to the client, cultural fit between client and supplier, perceived loss of organizational knowledge, prior outsourcing experience, external pressure, market volatility, and suppliers’ power) influence the outsourcing decision of e-banking services. The findings also confirmed that the nature of the service and client IT capabilities did not exert any influence on the outsourcing decision.

The study is among the first kind of ITO decision research which empirically investigates the effect of service observability, cultural fit, perceived loss of organizational knowledge, external pressure, market volatility, and suppliers’ power amongst other factors on the ITO decision. The findings from this study provide insights for the banks and service providers to better understand the factors affecting the outsourcing decisions of e-banking services in contexts of less developed countries. Implications based on a specific situation of the Iranian banking sector is also proposed.

This paper aims to provide an in-depth analysis toward understanding the critical factors in affecting information technology outsourcing (ITO) decision in the context of e-banking services in Iran. Within the recent decades, outsourcing IT processes and services as a strategic decision has been widely adopted throughout industries. In this regard, scholars have investigated a wide range of factors influencing ITO decision in various contexts.

This research examines a conceptual model that shows impacts of different attributes including technological, organizational and environmental on the Iranian banks’ ITO decision. To validate the research hypotheses, the partial least squares (PLS) technique for data analysis, is utilized.

The results of this study derived from the theoretical discussion of hypotheses illustrated that 9 of 11 assumed factors (i.e. perceived tangible benefits, perceived intangible benefits, perceived risks, perceived information security/privacy, complete contract establishment capability, making strong trustworthy relationship capability, uncertainty in business requirements, external pressure and market maturity) influence ITO decision in the target industry. The findings also confirmed that the size of the bank and competitors’ absorptive capacity did not exert any influence on their service outsourcing decision.

The sampling was confined to experts in the banking industry. Also, the results of this study reflect Iranian perspective. Consequently, generalization based on this sample would be interpreted cautiously and a limitation of the context should be kept in mind.

Insights into policymaking for suitable drivers to outsource e-banking services in the context of a less developed country are the main outcomes of the current research.

The purpose of this research was to uncover perceptions of information technology outsourcing (ITO) project leaders and project teams regarding knowledge transfer between client and vendor partners during opening and closing transition phases of ITO projects.

Qualitative methods and exploratory case study design were used. Purposeful sampling was used to identify ITO knowledge assets including project team members and organizational documents and artifacts that may provide information regarding the knowledge transfer processes during the transition phases of the ITO project. Sample criteria were ITO project team members from one US-based client organization and the company’s international vendor partners. The study population included project managers, analyst, developers, subject matter experts (SMEs) and other ITO knowledge workers involved in the ITO project from one US-based organization. Interview and document analysis were done using of NVivo Pro 11^® research software.

Four themes emerged from participant responses relative to the opening and closing phases of ITO projects including KT approaches to plans and processes; KT dependencies relative to IT project team member’s reliance on project tools, processes and artifacts; determinants of KT success or failure relative to project team members’ perceptions; and role of documentation relative to communication and distribution of KT outcomes.

This research may provide insights into additional aspects of knowledge transfer during ITO transition phases, which may be used by IT leaders and project teams to plan for successful knowledge transfer during the transition phases of ITO projects.

The information technology (IT) outsourcing (ITO) decision is a key issue in strategic and operational management and is considered a main critical factor influencing successful organizational performance and technology assessment. The purpose of this paper is to propose a framework combining value-focused thinking (VFT) methodology and the FITradeoff method to support decisions regarding ITO.

This study answers the following questions: How to identify, in a structured way, the objectives that should be considered in an ITO decision process in a changing environment? How to identify new IT services to be outsourced from the established objectives? The VFT method is recommended in this case to structure and model the problem. Moreover, the FITradeoff multicriteria method was considered in this study to support the evaluation and prioritization of IT services in an ITO decision

The framework provides promising results for ITO decisions. This study revealed that a lack of strategic and fundamental objectives is a critical issue in making ITO decisions. Although the VFT methodology is subjective in nature, it promotes a better understanding of goals and values, and FITradeoff allows the decision-maker to make comparisons of consequences based on his/her preferences.

The recommendations of the study are restricted to the case study and cannot be generalized. In addition, applying the method requires attention in determining the criteria used for outsourcing IT.

The strategic analysis of ITO provides a holistic view of the current situation since (i) the VFT methodology enables the IT manager to generate new alternatives to assist future decisions and (ii) FITradeoff has been demonstrated as a suitable option to evaluate ITO decisions.

To the best of our knowledge, this is the first paper to utilize a problem structuring method (VFT) to identify criteria and alternatives based on the organizational values and objectives. This is integrated with a multicriteria method that uses partial information and may consequently lead to fewer inconsistencies (FITradeoff) in the context of ITO.

The purpose of this paper is to explore the influence of PRINCE2 (PRoject IN Controlled Environments 2) standard on customer satisfaction jointly with vendor relationship management capability in the information technology outsourcing (ITO) context. This paper further tries to explore the above underlying mechanism by studying the mediating effect of deliverable quality.

This paper develops a mediated moderation model to explain the underlying influence processes of PRINCE2 standard, vendor relationship management capability and deliverable quality on ITO customer satisfaction. By conducting a pair-wise survey of 260 project managers in seven Iranian firms, the model and hypotheses are empirically tested with the partial least squares method.

Our results suggest that firms benefit more in terms of IT costs reduction when they have a higher level of complementary investment in an external standard, especially through an interplay effect of the external standard and internal relational aspect. Firms can make business processes more amenable to outsourcing and facilitate monitoring of vendor performance and effective coordination with vendors. More interestingly, we find that this interactive effect is fully mediated by deliverable quality, which, in turn, directly increases ITO customer satisfaction.

This study adds some new knowledge and provides new views to study ITO customer satisfaction by addressing the importance of PRINCE2 standard. This study further enhances our understanding in terms of the underlying pathway through which the PRINCE2 standard jointly affects customer satisfaction with vendor relationship management capability and deliverable quality. With the effort of explicitly explaining the complex mechanisms, this study helps ITO managers proactively escort outsourcing activities and projects.

Indium tin oxide (ITO) thin film as a gas sensor has a good stability and performance. The purpose of this paper is to compare the effect of depositing different metal layers in various structures on the gas sensing properties of ITO toward ethanol and carbon dioxide.

In this work, the authors have investigated the effect of depositing an ITO layer by Electron Beam Evaporation technique under, on top and in the middle of the metal layers. Surface morphology and the response of the fabricated sensors were compared and the changes in the response of the sensors to ethanol and carbon dioxide gases were studied at various gas concentrations and operating temperatures. The sensing mechanism and result of the other studies were also discussed.

Comparing various sensor structures reported in this study showed that the ITO nanorods which grow over distinct Ag nano-islands in the ITO/Ag structure has the highest response of 420 per cent to ethanol which is 6 times more than the single-layer ITO sensor. Further, gold nanoparticles on ITO nanorods in Au/ITO/Ag structure produce a very complex structure that exhibits the best response of 150 per cent to carbon dioxide which is 6.5 times more than the single-layer ITO sensor. The response and the recovery times were improved also.

Different ITO-metal gas sensor structures were studied and compared toward ethanol and carbon dioxide. Response enhancement and various surface changes through a series of experiments and analysis were discussed and compared to the literature.

IT outsourcing (ITO) has developed into an established practice for organizations but the interorganizational and oftentimes international collaboration it involves comes at a price: Reports from academia and practice suggest that more than 25% of all ITO projects fail, many because of cultural differences between client and provider organizations. Against this background, this paper analyzes the complex nature of cultural distance and its multi-faceted effect on ITO success.

This paper builds upon extant literature on culture on the national, organizational and team level, conceptualizes its effect on relationship quality and ITO success, and hypothesizes a model on potential moderators and management techniques to offset culture-induced challenges. It then evaluates and refines the model by means of an interpretive qualitative research design for an in-depth single-case study of ProSiebenSat.1 Media SE (P7S1), a leading European media company that reconfigured its IT sourcing model three times in 10 years.

The results from interviews with top managers from client and provider organizations represent one of the first integrated views on the critical importance of cultural compatibility on multiple levels, provide manifold examples for its complex effect on ITO success, as well as moderators and potential management techniques to promote ITO success.

This paper contributes relevant empirical insights to the growing body of literature on culture and its underestimated role in ITO success. It builds on tentative theory that is confirmed and refined.

The paper helps in substantiating the complex and intangible nature of culture and demonstrates means for its effective management.
