Exploring determinants of consumers' attitudes toward real-time bidding (RTB) advertising
Authors: Zhang Sixuan , Wakefield Robin , Huang Jinsong , Li Xi 
Published: June 2020

PurposeSince its inception in 2009, the growth of real-time bidding (RTB) advertising has been dramatic. Yet, there is a dearth of research in the information system (IS) literature despite the potential for negative e-commerce outcomes. The purpose of this paper is to identify salient antecedents of users’ attitude toward RTB advertisements.Design/methodology/approachA research model was constructed and tested with data from 437 respondents. SmartPLS 3.0, a partial least square (PLS) structural equation modeling (SEM) tool, was used to evaluate the research model and test the hypotheses.FindingsThe findings indicate that user attitude is determined by opposing influences from the cognitive and affective attributes of an RTB advertisement. A surprise is found to elicit greater perception of advertisement personalization, timeliness and relevance, as well as privacy and intrusiveness concerns. While RTB advertisement relevance appears to lessen the effect of advertisement intrusiveness, privacy concern is exacerbated when the advertisement is more personalized. The authors discuss the implications of this study for click-through intentions and e-commerce.Originality/valueAt this point in the evolution of RTB advertising, the findings indicate that the surprise generated by the appearance of an RTB advertisement is not currently a “bad” surprise. In addition, the formation of positive user attitude toward RTB is complex because cognitive factors interact with users' concerns to strengthen or weaken the negative effects. The authors also demonstrate that attitude and stimulus–organism–response (S–O–R) theories are useful theoretical bases for the development of causal models to predict RTB attitude and click-through intentions.
Trade show networks, trust and organizational learning: the effect of network ties
Authors: Bettis-Outland Harriette , Mora Cortez Roberto , Johnston Wesley J. 
Published: June 2020

Purpose
This paper aims to evaluate the behavior of micro and macro business networks in a trade show context. The following questions are addressed: How do business networks impact organizational learning at trade shows? Can relational ties between networks influence organizational learning? Does trust play a role between different network types and organizational learning?

Design/methodology/approach
The theoretical framework for this research is based on the broad spectrum of social exchange theory (Cropanzano and Mitchell, 2005; Foa and Foa, 1974, 1980; Kelley and Thibault, 1978; Kelley, 1997). Social exchange theory has several different interpretations; one common view of this theory involves a series of interactions that result in obligations for the participating members (Emerson, 1976; Cropanzano and Mitchell, 2005). This model extends the Levin and Cross (2004) model presented in their article, “strength of weak ties you can trust: the mediating role of trust in effective knowledge transfer”.

Findings
This paper is a review and synthesis of trade show, trust, organizational learning and business network literature. This conceptual paper concludes with eight propositions, which delve into connections between micro and macro networks, strong and weak ties in these networks and the effect on organizational learning. Trust is the mediating variable between networks and organizational learning. High levels of trust could change the learning approach (adaptive, generative or transformative) of the different networks.

Research limitations/implications
The propositions integrate extant research on trade shows and will guide future research regarding the relationship between types of business networks, trust and organizational learning.

Practical implications
This conceptual paper looks at trade shows from a network perspective; specifically, how do trade show networks impact organizational learning. Trade show participation results in different approaches to organizational learning, which can be modified based on the level of trust that exists between network members. Trade show participation enables both adaptive and generative learning. However, atypical interactions between business networks occasionally produce transformative learning.

Originality/value
This conceptual paper offers an innovative approach to trade show research by analyzing the relationship between trade shows and organizational learning from a network perspective, using trust as the mediating variable.
Marketing-specific intellectual capital: conceptualization, scale development and empirical illustration
Authors: Peñalba-Aguirrezabalaga Carmela , Sáenz Josune , Ritala Paavo 
Published: June 2020

PurposeThe aims of this paper are to identify and classify the knowledge resources that shape intellectual capital (IC) within the marketing function, to develop and validate a related scale and to demonstrate the scale's applicability in an empirical context.Design/methodology/approachA literature-based approach was adopted to identify and classify knowledge assets in the field of marketing. The new scale's content was then tested in a number of companies with different profiles. A subsequent survey of a representative sample of 346 Spanish firms sought to validate the scale and to assess those companies' marketing-related IC.FindingsThe literature search provided the basis for a marketing-related IC architecture comprising three main categories, nine subcategories and eighty items whose validity was tested and confirmed. The survey revealed that marketing-specific human capital (HC) is the most developed knowledge resource in Spanish firms, followed by marketing-specific relational capital (RC), while marketing-specific structural capital (SC) is the least developed. Significant differences were also found among companies with different profiles (B2C vs B2B, high-tech vs low-tech and manufacturing vs services).Originality/valueThis study makes a valuable contribution to the IC literature as one of the first to deploy the general IC framework in a specific functional area (here: marketing and sales) for more meaningful and in-depth assessment of firm-specific knowledge resources.
Intellectual capital and corporate governance: an evaluation of Oman's financial sector companies
Authors: Dalwai Tamanna , Mohammadi Syeeda Shafiya 
Published: June 2020

PurposeThe purpose of this study is to empirically investigate the relationship between intellectual capital and corporate governance of Oman's financial sector companies. Intellectual capital has been found to successfully contribute to the economic wealth creation of firms in germane literature. Unfortunately, financial statements do not necessarily capture and reflect the contributions of intellectual capital, thereby leading to an information asymmetry between companies and users of financial statements. The research also investigates the relationship between corporate governance and intellectual capital efficiency across various financial subsectors.Design/methodology/approachData are collected from annual reports available on Muscat Securities Market for 31 listed financial sector companies for the period 2012 to 2016 and analyzed using a multiple regression model. Intellectual capital is measured using Pulic's efficiency measure of value-added intellectual coefficient (VAIC). Corporate governance individual components such as board characteristics, audit committee characteristics and ownership structure are presented as independent variables.FindingsThe findings suggest that board size and frequency of audit committee meetings have a significant association with the intellectual capital efficiency of Oman's financial sector. VAIC and human capital efficiency of banks are also significantly influenced by most of the corporate governance mechanisms; however, other subsectors do not report such findings. Corporate governance of banks in comparison to other subsectors effectively engages in utilizing the potential of intellectual capital efficiency. Agency theory and resource dependency theory find limited support as a result of this study. The GMM results are not robust to the alternative instruments.Research limitations/implicationsThe sample size is small as the study is limited to the listed financial sector of Oman. Future studies can be extended to include all of Oman's or GCC’s listed companies. Additionally, the intellectual capital is measured using the construct of VAIC which suffers some limitations and can be overcome using other tools such as content analysis.Practical implicationsThe findings of this study suggest that Oman's regulators can create an awareness strategy on highlighting the importance of intellectual capital for companies (board of directors and managers), investors, debtors and creditors. Further, Oman's Capital Market Authority and Muscat Securities Market need to strengthen the regulations related to intellectual capital.Originality/valueThis study extends intellectual capital and corporate governance literature by presenting the research outcome for Oman's financial sector. It is useful for Oman's financial sector companies to direct corporate governance measures for driving value creation of firms through the management of intellectual capital efficiency.
Measures that matter: an empirical investigation of intellectual capital and financial performance of banking firms in Indonesia
Authors: Soewarno Noorlailie , Tjahjadi Bambang 
Published: June 2020

PurposeThis study aims to investigate the intellectual capital–financial performance relationship using two models, namely the conventional Value-Added Intellectual Coefficient (VAIC) model and the adjusted Value-Added Intellectual Coefficient (A-VAIC) model.Design/methodology/approachThis study is designed as a quantitative research focusing on the relationship between intellectual capital and financial performance of the banking industry in Indonesia. As many as 114 data are derived from the publicly listed banks on the Indonesia Stock Exchange for the period of 2012–2017. The multiple regression analysis is employed to test the hypotheses studied.FindingsIn general, the result confirms that intellectual capital affects financial performance. Although not all hypotheses of the study are supported by either the VAIC model or the A-VAIC model, the results provide a deeper and new insight on how each component of intellectual capital efficiency (human capital, structural capital, capital employed, innovation capital) relates to financial performance (return on asset, return on equity, asset turnover, price to book ratio). The results also justify that further improvements in measuring intellectual capital are still needed in the future.Research limitations/implicationsThis study limits its generalization since the sample is only in the Indonesian banking industry. Notwithstanding the limitation, the results imply that the Indonesian banking managers need to be aware of intellectual capital management because of its strategic role in enhancing financial performance.Practical implicationsThis study contributes to the intellectual capital literature by providing empirical evidence on the use of both models, namely the conventional VAIC and the A-VAIC in the Indonesian banking industry research setting which is never been studied before.Social implicationsThis study has the social implication to the enhancement of the quality life of the society. The higher the quality of intellectual capital in the banking firms, the better the banks serve the needs of the community.Originality/valueThis study contributes to the IC literature by providing empirical research on the use of the VAIC model and the A-VAIC model in the Indonesian banking industry.

Authors: Nath Subrata Deb , Gupta Gautam , Kearns Martin , Gulsoy Ozkan , Atre Sundar V. 
Published: June 2020

Purpose
The purpose of this paper is to investigate effects of layer thickness on densification, surface morphology, microstructure and mechanical and corrosion properties of 420 stainless steel fabricated by laser-powder bed fusion (L-PBF).

Design/methodology/approach
Standard specimens were printed at layer thickness of 10, 20 and 30 µm to characterize Archimedes density, surface roughness, tensile strength, elongation, hardness, microstructural phases and corrosion performance in the as-printed and heat-treated condition.

Findings
Archimedes density slightly increased from 7.67 ± 0.02 to 7.70 ± 0.02g/cm3 and notably decreased to 7.35 ± 0.05 g/cm3 as the layer thickness was changed from 20 µm to 10 and 30 µm, respectively. The sensitivity to layer thickness variation was also evident in properties, the ultimate tensile strength of as-printed parts increased from 1050 ± 25 MPa to 1130 ± 35 MPa and decreased to 760 ± 35 MPa, elongation increased from 2.5 ± 0.2% to 2.8 ± 0.3% and decreased to 1.5 ± 0.2, and hardness increased from 55 ± 1 HRC to 57 ± 1 HRC and decreased to 51 ± 1 HRC, respectively. Following heat treatment, the ultimate tensile strength and elongation improved but the general trends of effects of layer thickness remained the same.

Practical implications
Properties obtained by L-PBF are superior to reported properties of 420 stainless steel fabricated by metal injection molding and comparable to wrought properties.

Originality/value
This study successfully the sensitivity of mechanical and corrosion properties of the as-printed and heat-treated parts to not only physical density but also microstructure (martensite content and tempering), as a result of changing the layer thickness. This manuscript also demonstrates porosity evolution as a combination of reduced energy flux and lower packing density for parts processed at an increasing layer thickness.

Published: June 2020

SummaryPhylogenetic analysis of more than 4000 annotated bacterial acid phosphatases was carried out. Our analysis enabled us to sort these enzymes into the following three types: (1) class B acid phosphatases, which were distantly related to the other types, (2) class C acid phosphatases and (3) generic acid phosphatases (GAP). Although class B phosphatases are found in a limited number of bacterial families, which include known pathogens, class C acid phosphatases and GAP proteins are found in a variety of microbes that inhabit soil, fresh water and marine environments. As part of our analysis, we developed three profiles, named Pfr‐B‐Phos, Pfr‐C‐Phos and Pfr‐GAP, to describe the three groups of acid phosphatases. These sequence‐based profiles were then used to scan genomes and metagenomes to identify a large number of formerly unknown acid phosphatases. A number of proteins in databases annotated as hypothetical proteins were also identified by these profiles as putative acid phosphatases. To validate these in silico results, we cloned genes encoding candidate acid phosphatases from genomic DNA or recovered from metagenomic libraries or genes synthesized in vitro based on protein sequences recovered from metagenomic data. Expression of a number of these genes, followed by enzymatic analysis of the proteins, further confirmed that sequence similarity searches using our profiles could successfully identify previously unknown acid phosphatases.
Conceptualising policy for sustainable agriculture development
Authors: Clune Timothy 
Published: June 2020

AbstractPolicy frameworks supporting sustainable agriculture development are critical in the delivery of the food and fibre needs of a burgeoning global population. A sustainable and resilient Australian agriculture sector is considered essential if it is to capitalise on the world's growing food and fibre needs. However, an increasingly dynamic climate, changing demographics of regional Australia, and economic factors in a global market constrain sustainable development of the agriculture sector. Although current policy supports investment in research and development and infrastructure, action to increase market access and competitiveness, as well as a suite of agricultural welfare options, it is flawed in its failure to contemplate the relative readiness of individuals and businesses to act on the interventions of government. This paper proposes the adoption of the capability approach to refocus the policy framework to prioritise delivery of outcomes that are valued by individuals and businesses. It proposes a conceptual model that provides a scalable, continuous improvement structure against which policy action can be implemented, monitored, evaluated, and adapted enabling design of more holistic agriculture policy settings that support the sustainable development of the sector and ensure that it can capture the opportunities of future global food and fibre demand.
Independent review of emergency economic stimulus measures: Global Financial Crisis and COVID‐19
Authors: Wilkins Peter , Gilchrist David , Phillimore John 
Published: June 2020

AbstractMajor government emergency interventions demand, and generally receive, independent scrutiny. This article looks back at reviews of the Australian government's economic stimulus measures introduced in the aftermath of the 2008 Global Financial Crisis (GFC), in anticipation of reviews of responses to the COVID‐19 emergency, noting similarities and differences between the two crises. We examine 10 independent reviews of the Australian government's response to the GFC with a particular focus on their nature and the context in which they occurred. As a result, we identify five themes: when and how often reviews are conducted; recognition of context; the need for clear program objectives; explicit design principles; and governance. We develop a typology of independent reviews that has three key and interrelated dimensions: purpose, timing, and reviewer. We observe that there was patchwork coverage of the GFC measures, with no single report providing a holistic assessment of what was achieved or lessons learnt. We contend that, notwithstanding differences between crises, the typology will aid understanding of the role, key issues, and contributions of reviews that have already been, or will be, commissioned into COVID‐19 and future emergency economic stimulus measures.
Mortality and renal prognosis in isolated metformin‐associated lactic acidosis treated with continuous renal replacement therapy and citrate‐calcium‐anticoagulation
Authors: Uusalo Panu , Järvisalo Mikko J. 
Published: June 2020

IntroductionUse of metformin increases plasma lactate concentration and may lead to metformin‐associated lactic acidosis (MALA). Previous studies have suggested severe MALA to have a mortality of 17%‐21%, but have included patients with other coincident conditions such as sepsis. The treatment of choice is continuous renal replacement therapy (CRRT), which has been performed using heparin analogues or no anticoagulation in former studies.Materials and MethodsPatients admitted to the Intensive Care Unit of Turku University Hospital Finland with lactic acidosis without any other recognizable etiology than concomitant metformin treatment who required CRRT between years 2010 and 2019 were included. CRRT was performed using regional citrate‐calcium‐anticoagulation. Data extracted included patient demographics, comorbidities, and clinical parameters at 6‐hour intervals about 72 hours from admission. Creatinine and estimated glomerular filtration rate (eGFR) were measured at 1 year after MALA.ResultsA total of 23 patients with isolated MALA were included in the study. Median (IQR) pH was 6.88 (6.81‐7.07) and lactate 16.1 (11.9‐23.0) mmol/L on admission. Median (IQR) duration of CRRT was 62 (41‐70) hours. Seven patients (30%) required mechanical ventilation with a mean duration of 6.0 ± 3.0 days. 90‐day mortality was 4.3% and 1‐year mortality 13.0%. Creatinine (P = .02) and eGFR (P = .03) remained significantly altered at 1 year of follow‐up compared to baseline.ConclusionsMALA can be treated effectively and safely with CRRT and citrate‐calcium‐anticoagulation, usually required for 2‐3 days. Mortality of patients with MALA treated with CRRT is low when other conditions inducing lactic acidosis are excluded. MALA episode may be associated with long‐lasting kidney injury.

Published: June 2020

AbstractProblemThe mechanism(s) by which antinuclear antibodies (ANA) induce implantation failure are not clear, and little information regarding the function of autoantibodies in reproductive tissues is available.Methods of StudyA total of 380 patients who underwent in vitro fertilization and embryo transfer (IVF‐ET) were divided into control, serum positive, and follicular fluid (FF) positive groups based on the results of indirect immunofluorescence assay for ANA in the serum and FF. Immunofluorescence assay was performed to evaluate the existence of ANA in granular cells and endometrial tissues. Presence in FF of soluble apoptotic markers, including Bcl‐2, Caspase‐3, cleaved PARP, Cytochrome C, GAPDH, and p53, was assessed using magnetic bead based assays.ResultsThe patients in the FF positive group had the lowest numbers of retrieved oocytes, fertilizations, and high‐quality embryos. The fertilization rate, and the proportion of two pronuclear (2PN) embryos in patients in the FF positive group were significantly lower than those in the other two groups. The FF positive group also had the lowest clinical pregnancy rate, and the highest early miscarriage rate. Granulosa cells and endometrial tissues in patients in the FF positive group were ANA positive. High levels of BCL‐2, Caspase‐3, Cytochrome C, GAPDH, and p53 were found in the FF of patients in the FF positive group.ConclusionsAntinuclear antibodies in FF and endometrial tissues may cause imbalanced apoptosis, resulting in poor IVF‐ET treatment outcomes. Local autoimmunity and cell apoptosis in reproductive tissues could be considered new therapeutic targets for improving IVF‐ET treatment efficacy.
