Author supplied from the article: Abstract A temperature compensated hydrogen sensor was designed and made capable of detecting H2 within a broad range of 100–10.000 ppm while compensating instantaneously for large (±25 °C) temperature variations. Two related operational constraints have been simultaneously addressed: (1) Selective, and sensitive detection under large temperature changes, (2) Fast warning at low and increasing H2 levels. Accurate measurements of hydrogen concentrations were enabled by matching relevant time-constants. This was achieved with a microchip having two temperature coupled palladium nanowires. One of the H2 sensitive Pd nanowires was directly exposed to hydrogen, whilst the other nanowire was used as a temperature sensor and as a reference. A drop forging technique was used to passivate the second Pd wire against H2 sensing. Temperature effects could be substantially reduced with a digital signal processing algorithm. Measurements were done in a test chamber, enabling the hydrogen concentration to be controlled over short and long periods. An early response for H2 sensing is attainable in the order of 600 milliseconds and an accurate value for the absolute hydrogen concentration can be obtained within 15 s.

In recent years business process management (BPM) and specifically information systems that support the analysis, design and execution of processes (also called business process management systems (BPMS)) are getting more attention. This has lead to an increase in research on BPM and BPMS. However the research on BPMS is mostly focused on the architecture of the system and how to implement such systems. How to select a BPM system that fits the strategy and goals of a specific organization is largely ignored. In this paper we present a BPMS selection method, which is based on research into the criteria that are important for organizations, which are going to implement a BPMS.

From Science direct: One of the nanowires was covered with a 2-Hydroxyethyl methacrylate based compound to prevent hydrogen from reaching the wire. The compound was dried by a UV source and tested in chamber for comparison with previous measurements. The results shows that temperature effects can be reduced by a digital signal processing algorithm without measuring temperature near or at the substrate. With this method no additional temperature probes are necessary making this solution a candidate for ultra low power wireless applications.

Study level/applicability Teaching formats for both BA/MA students and MBA/PhD students in sustainable entrepreneurship and strategic management are offered in the teaching notes. Subject area This case juxtaposes the company’s core values of gender equality, sustainability and inclusivity, with the financial pressures of expanding global operations in COVID-19 times. Case overview This case illustrates the founding and growth of i-did in the broader context of the global circular textile industry. Being the first company that reclaims value of discarded textiles by making design products out of felt, the dilemma is on how i-did can create a blueprint for sustainable leadership in a scalable (financial) business case. Expected learning outcomes The learning outcomes of this case are as follows: to understand the concepts of circular economy and social impact and how they can be translated to business; to apply their knowledge of strategy and entrepreneurship for sustainable business innovation; to be able to analyze a company according to the Sustainable Development Goals, specifically around gender issues, inclusivity and diversity; to evaluate opportunities for multiple value creation in business; and to have the knowledge and capacity to create a circular business with the help of the Business Model Template. Social implications This case engages students in critically reflecting on sustainability concepts in relation to i-did (theoretical value) and applying novel business model innovation tools to a real-world enterprise (practical value). The students get the chance to explore the ethical challenges the two entrepreneurial leaders face between short-term economic gains (or maybe even survival) and their core values of (gender) inclusivity, circularity and diversity. Supplementary materials Teaching notes and a summarizing two-pager are available for educators. Poldner, K. and Blanken, R.

Europeans live their lives at a time when certain collective expectations of how the world should function no longer seem to describe their experience of what actually happens. This bifurcation of experience and expectation is causing some severe symptoms of dislocation. Truth turns relative and his- tory seems in need of radical revision. Even time itself seems topsy-turvy, in a way that some Messianic beliefs find very much to their taste. This is the hallmark of the contemporary moment and why, this essay will argue, that in lieu of any other generalising term, we need to make the most use of ‘contemporary’ and ‘contemporaneity’ for emancipatory purposes.

From the article: "After 1993, the concept of strategic alignment is evaluated from the connection between IT and business to much broader definitions in which the connection between all business functions, horizontally and vertically, and later also with projects and stakeholders is mentioned. To achieve stategic alignment there must be a coordination between the strategy of organizations and those who contribute to the implementation of the strategy and the actual performance of an organization. This process is called Human Oriented Performance Management (HOPM). The HOPM model consists of four dimensions: strategy translation, information and visualization, dialogue and action orientation, and continues improvement and organizational learning. To measure the effect of strategic alignment a range of financial performance indicators are used. Based on a literature review this paper explores which financial performance indicators could be used to measure the effect of HOPM. The literature was selected over a period from 1996 – 2015. The research is not only focused on the top of the strategy map, but also on the cause-effect relationships in the strategy map. The underlying performance indicators in the strategy map can show on which figures the dialogue in the HOPM model about strategy implementation must be based. This dialogue is the input to action in which strategic alignment comes about. The goal of the research is to optimize this dialogue by looking for performance indicators that can show the effect of HOPM" The article is used for the course: 'corporate policy' minor MSMM (Masterclass Strategic Marketing Management).

In recent years, the debate about the design of the monetary system has become increasingly prevalent. A major topic within this debate is central bank digital currency or CBDC for short. A survey by the Bank of International Settlements (BIS) shows that in 2022, nine in ten central banks (CB) explored a digital variant of their own currency (Kosse & Mattei, 2022). In the euro area, the European Central Bank (ECB) is conducting a wide-range study of the pros and cons of a CBDC, in the form of a digital euro. Other CBs are at different stages of the research cycle. The Chinese central bank is experimenting extensively with its e-CNY and has been conducting research since 2014 (Luo, 2022; Prasad, 2021). The Swedish Riksbank published its first report on the possible designs and effects of the e-krona in September 2017 (Sveriges Riksbank, 2017). Against all these various studies and experiments is the Bahamian Sand dollar, the world's first, by 2020, fully implemented CBDC. The Bahamas is not the only country; in 2022, Jamaica fully introduced the JAM-DEX (CBDC Tracker, 2023). Since CBDCs are a relatively new phenomenon, there is logically little empirical data to support the potential advantages and disadvantages. The fully implemented Sand dollar can confirm or refute some of the claimed theoretical advantages and disadvantages, and lessons can be distilled from this case for the introduction of other CBDCs. This paper first discusses the (theoretical) motivations for implementing the Sand dollar, then discusses its operation and current low adaptation rates. Finally, it derives lessons that can be used in other CBDC cases.

Het besef groeit dat het stedelijk groen meer is dan ecologie en biodiversiteit. Dat besef is in het hedendaagse groenbeheer nog geen gewoongoed. Daarom willen we vanuit de praktijk van Hogeschool Van Hall Larenstein in dit boek proberen aan te geven wat er in het groenbeheer mogelijk is met strategische inzet van groen in de stad, en welke competenties groenbeheerders hiervoor nodig hebben.

Saliva diagnostics have become increasingly popular due to their non-invasive nature and patient-friendly collection process. Various collection methods are available, yet these are not always well standardized for either quantitative or qualitative analysis. In line, the objective of this study was to evaluate if measured levels of various biomarkers in the saliva of healthy individuals were affected by three distinct saliva collection methods: 1) unstimulated saliva, 2) chew stimulated saliva, and 3) oral rinse. Saliva samples from 30 healthy individuals were obtained by the three collection methods. Then, the levels of various salivary biomarkers such as proteins and ions were determined. It was found that levels of various biomarkers obtained from unstimulated saliva were comparable to those in chew stimulated saliva. The levels of potassium, sodium, and amylase activity differed significantly among the three collection methods. Levels of all biomarkers measured using the oral rinse method significantly differed from those obtained from unstimulated and chew-stimulated saliva. In conclusion, both unstimulated and chew-stimulated saliva provided comparable levels for a diverse group of biomarkers. However, the results obtained from the oral rinse method significantly differed from those of unstimulated and chew-stimulated saliva, due to the diluted nature of the saliva extract.
