The purpose of this paper is to study the effect of whey and whey components on the production of dialyzable non‐heme iron – an in vitro indicator of bioavailable forms of the mineral.

Whey, processed whey and whey components were mixed with ferric iron and digested in vitro with pepsin and pancreatin/bile using a dialysis bag containing bicarbonate for pH adjustment. Total and ferrous dialyzable iron were measured and compared to values from protein and non‐protein controls.

Whey produced much more dialyzable iron than egg albumin but less than deproteinized whey. Most of the iron was ferric. Whey protein concentrate was as effective as egg abumin but whey protein isolate, α‐lactalbumin and β‐lactoglobulin slightly reduced dialyzable iron formation. Milk salts produced more dialyzable iron than whey and about as much as deproteinized whey. The major component of whey producing dialyzable iron was citrate, which competes for iron chelation with the whey protein.

This study demonstrates that whey generates a large amount of dialyzable iron from ferric iron sources and that the iron is primarily due to chelation with citrate rather than to digestion of whey proteins. However, the effect of citrate is reduced by whey proteins.

This study aims to explore the relationship between IT and HRM in the context of manufacturing SMEs, more specifically the relationship between strategic HRM and e-HRM as well as the performance effects of this relationship. The conceptual framework is founded upon the resource-based view (RBV), specifically upon the strategic HRM and e-HRM capabilities of SMEs and upon the strategic alignment of these capabilities in the form of capability configurations or “gestalts.”

To answer the research questions, a questionnaire was constructed and mailed to 1854 manufacturing SMEs in the province of Quebec, Canada, producing 216 valid responses that were used for statistical analysis purposes. Capability configurations were identified through a cluster analysis of the e-HRM and strategic HRM capabilities developed by these firms.

Using structural equation modeling to validate the research model, a causal analysis confirmed a positive influence of the sampled SMEs’ strategic orientation upon their development of strategic HRM capabilities. More importantly, a higher level of alignment between the SMEs’ strategic HRM and e-HRM capabilities was associated to a higher level of strategic HRM performance.

To our knowledge, ours is the first study to show interest in the effect of the strategic alignment of HRM and IT capabilities upon HRM performance, by adopting a configurational perspective and considering organizational IT from a functional point of view. Given the specific context of SMEs, the focus was on e-HRM capabilities related to the IT infrastructure of these organizations and the IT competencies of individuals related to HRM.

This research provides accounting-ethics authors and administrators with a benchmark for accounting-ethics research. While Bernardi and Bean (2010) considered publications in business-ethics and accounting’s top-40 journals this study considers research in eight accounting-ethics and public-interest journals, as well as, 34 business-ethics journals. We analyzed the contents of our 42 journals for the 25-year period between 1991 through 2015. This research documents the continued growth (Bernardi & Bean, 2007) of accounting-ethics research in both accounting-ethics and business-ethics journals. We provide data on the top-10 ethics authors in each doctoral year group, the top-50 ethics authors over the most recent 10, 20, and 25 years, and a distribution among ethics scholars for these periods. For the 25-year timeframe, our data indicate that only 665 (274) of the 5,125 accounting PhDs/DBAs (13.0% and 5.4% respectively) in Canada and the United States had authored or co-authored one (more than one) ethics article.

This chapter adopts a problem-solving perspective to analyze the competitive dynamics of innovation ecosystems. We argue that features such as uncertainty, complexity, and ambiguity, entail different knowledge requirements which explain the varying abilities of focal firms to coordinate the ecosystem and benefit from the activities of their suppliers, complementors, and users. We develop an analytical framework to interpret various instances of coupling patterns and identify four archetypical types of innovation ecosystems.

Purpose: The purpose of this study is to assess the main and interaction effects of activity-based costing (ABC), internal information systems integration (IISI), and external information systems integration (EISI) on manufacturing plant operational performance, controlling for plant characteristics.

Methodology/approach: The study uses survey data from a cross-section of 369 U.S. manufacturing plants. Data were analyzed using hierarchical regression model.

Findings and implications: The results indicate partial support for the main and two-way interaction effects on plant operational performance. The three-way interaction effects are significant and positive, suggesting that deploying all three resources (i.e., ABC, IISI, and EISI) leads to the higher plant operational performance.

Originality/value: The paper significantly extends prior research and contributes to the understanding of the main and interaction effects of ABC, IISI, and EISI on manufacturing plant operational performance. The paper would also be of interest to practitioners interested in keeping up with academic literature.

The appearance of social media in small and medium enterprise (SME) business operations seems to be increasing in recent years. SME owners have started to understand that digital marketing tools can benefit their businesses significantly. Hence, in this study, we explore further the relationship between organisations and customers, and how SMEs use social media as an opportunity to develop their enterprises. We report the results by relying on qualitative methods to explore the insights from a wider stakeholder perspective. The findings contribute to the existing literature in agreement with the latest theories that SMEs in Greece are aware of the hidden opportunities and try to apply branding with the combination of social media. This study explores further the role of electronic word of mouth (eWOM) in a business transition, customers' experience and competitive business advantage.

The quality of students' relationships with their teachers plays a significant role in their success in school. Social and emotional learning (SEL) curriculums show great promise for supporting student development. However, quality implementation requires that teachers recognize and understand how their behavior and interactions with students impact the development of these skills. The Prosocial Classroom Model proposes that teacher social and emotional competencies (SECs) play a critical role in creating and maintaining a classroom where everyone feels safe, connected, and engaged in learning. In this chapter, we extend the understanding of SEC to include leadership styles as defined by evolutionary motivational systems theory. We argue that a critical dimension of effective SEL instruction and teacher SEC is effective leadership that skillfully applies an understanding of the social and emotional dimensions of classroom interactions that promote motivation, engagement, and learning. Implications for educational theory, policy and practice, and research are discussed.

This paper aims to examine the impact of research and development (R&D) investment on firms’ stock price from the perspective of investors.

Building on signaling theory, the authors propose that R&D investment sends important signals to the investment community regarding future growth, which in turn impacts investor reaction to such investment.

Using a sample of listed pharmaceutical firms in China from 2007 to 2011, the authors find that R&D investment has a positive effect on firms’ stock price, indicating that investors have a positive reaction to R&D investment signals. Further, the authors find that the signaling role of new product announcements mediates this relationship between R&D investment and investor reaction.

The authors also find that the signaling role of development capacity (DC) has a moderating effect on the relationship between innovation activities (i.e. R&D investment and new product announcements) and investor reaction, such that DC strengthens the positive effect of R&D and new product announcements on investors.
