Design/methodology/approach In-depth interviews and documentary analysis, analysed qualitatively, as well as a review of theoretical and empirical literature. Findings Public school teachers and public university lecturers in Uganda who frequently engage in industrial action mainly rationalise their engagement by the absence, or the ineffectiveness of alternative conflict resolution mechanisms. The findings also show that industrial action, even in resource-constrained settings like Uganda, is stimulated more by the desire to achieve equity rather than by the basic desire to improve working conditions. It is also notable that new, often unstructured, forms of workplace militancy continue to emerge in the public sector, and waves of industrial action are shifting from the industrial to the public sector. Practical implications Whereas industrial action is a protected labour right, the findings of this research strongly suggest that public employees do not necessarily enjoy their right to engage, but only reluctantly take industrial action as a "last resort". The findings will, therefore, help public managers and policymakers to appreciate their responsibility in reducing the compulsion for industrial action among public employees. Originality/value This paper provides a general explanation for industrial action from the perspective of the people involved, rather than explaining the causality of specific strike actions.

Therefore, the availability of reliable and robust co-transfection methods and defined selection criteria for their use in, e.g., expression of multimeric proteins or mixed RNA/DNA delivery is of utmost importance. Here, we investigated different co- and successive transfection approaches, with particular focus on in vitro transcribed messenger RNA (IVT-mRNA). Expression levels and patterns of two fluorescent protein reporters were determined, using different IVT-mRNA doses, carriers, and cell types. Quantitative parameters determining the efficiency of co-delivery were analyzed for IVT-mRNAs premixed before nanocarrier formation (integrated co-transfection) and when simultaneously transfecting cells with separately formed nanocarriers (parallel co-transfection), which resulted in a much higher level of expression heterogeneity for the two reporters. Successive delivery of mRNA revealed a lower transfection efficiency in the second transfection round. All these differences proved to be more pronounced for low mRNA doses. Concurrent delivery of siRNA with mRNA also indicated the highest co-transfection efficiency for integrated method. However, the maximum efficacy was shown for successive delivery, due to the kinetically different peak output for the two discretely operating entities. Our findings provide guidance for selection of the co-delivery method best suited to accommodate experimental requirements, highlighting in particular the nucleic acid dose-response dependence on co-delivery on the single-cell level.}, language = {en} } @article{NeufeldBobrovaDavletovetal.2020, author = {Neufeld, Maria and Bobrova, Anastacia and Davletov, Kairat and Stelemekas, Mindaugas and Stoppel, Relika and Ferreira-Borges, Carina and Breda, Joao and Rehm, J{\"u}rgen}, title = {Alcohol control policies in Former Soviet Union countries}, series = {Drug and alcohol review}, volume = {40}, journal = {Drug and alcohol review}, number = {3}, publisher = {Wiley}, address = {Hoboken}, issn = {0959-5236}, doi = {10.1111/dar.13204}, pages = {350 -- 367}, year = {2020}, abstract = {Issues The last Soviet anti-alcohol campaign of 1985 resulted in considerably reduced alcohol consumption and saved thousands of lives. But once the campaign's policies were abandoned and the Soviet alcohol monopoly broken up, a steep rise in mortality was observed in many of the newly formed successor countries, although some kept their monopolies. Almost 30 years after the campaign's end, the region faces diverse challenges in relation to alcohol. Approach The present narrative review sheds light on recent drinking trends and alcohol policy developments in the 15 Former Soviet Union (FSU) countries, highlighting the most important setbacks, achievements and best practices. Vignettes of alcohol control policies in Belarus, Estonia, Kazakhstan, Lithuania and Uzbekistan are presented to illustrate the recent developments.
Key Findings Over the past decade, drinking levels have declined in almost all FSU countries, paralleled by the introduction of various alcohol-control measures. The so-called three 'best buys' put forward by the World Health Organization to reduce alcohol-attributable burden (taxation and other measures to increase price, restrictions on alcohol availability and marketing) are relatively well implemented across the countries. Implications In recent years, evidence-based alcohol policies have been actively implemented as a response to the enormous alcohol-attributable burden in many of the countries, although there is big variance across and within different jurisdictions. Conclusion Strong declines in alcohol consumption were observed in the 15 FSU countries, which have introduced various alcohol control measures in recent years, resulting in a reduction of alcohol consumption in the World Health Organization European region overall.}, language = {en} } @article{ErmolinaTiberius2021, author = {Ermolina, Alena and Tiberius, Victor}, title = {Voice-controlled intelligent personal assistants in health care}, series = {Journal of medical internet research : international scientific journal for medical research, information and communication on the internet ; JMIR}, volume = {23}, journal = {Journal of medical internet research : international scientific journal for medical research, information and communication on the internet ; JMIR}, number = {4}, publisher = {Healthcare World}, address = {Richmond, Va.}, issn = {1438-8871}, doi = {10.2196/25312}, pages = {11}, year = {2021}, abstract = {Background: Voice-controlled intelligent personal assistants (VIPAs), such as Amazon Echo and Google Home, involve artificial intelligence-powered algorithms designed to simulate humans. Their hands-free interface and growing capabilities have a wide range of applications in health care, covering off-clinic education, health monitoring, and communication. However, conflicting factors, such as patient safety and privacy concerns, make it difficult to foresee the further development of VIPAs in health care.
Objective: This study aimed to develop a plausible scenario for the further development of VIPAs in health care to support decision making regarding the procurement of VIPAs in health care organizations. Methods: We conducted a two-stage Delphi study with an internationally recruited panel consisting of voice assistant experts, medical professionals, and representatives of academia, governmental health authorities, and nonprofit health associations having expertise with voice technology. Twenty projections were formulated and evaluated by the panelists. Descriptive statistics were used to derive the desired scenario.
Results: The panelists expect VIPAs to be able to provide solid medical advice based on patients' personal health information and to have human-like conversations. However, in the short term, voice assistants might neither provide frustration-free user experience nor outperform or replace humans in health care. With a high level of consensus, the experts agreed with the potential of VIPAs to support elderly people and be widely used as anamnesis, informational, self-therapy, and communication tools by patients and health care professionals. Although users' and governments' privacy concerns are not expected to decrease in the near future, the panelists believe that strict regulations capable of preventing VIPAs from providing medical help services will not be imposed.
Conclusions: According to the surveyed experts, VIPAs will show notable technological development and gain more user trust in the near future, resulting in widespread application in health care. However, voice assistants are expected to solely support health care professionals in their daily operations and will not be able to outperform or replace medical staff.}, language = {en} } @article{LassGronau2020, author = {Lass, Sander and Gronau, Norbert}, title = {A factory operating system for extending existing factories to Industry 4.0}, series = {Computers in industry : an international, application oriented research journal}, volume = {115}, journal = {Computers in industry : an international, application oriented research journal}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0166-3615}, doi = {10.1016/j.compind.2019.103128}, pages = {8}, year = {2020}, abstract = {Cyber-physical systems (CPS) have shaped the discussion about Industry 4.0 (I4.0) for some time.

In particular, insured individuals with a healthy lifestyle can receive a reduction of their contributions to be paid. However, this potential is hardly used in practice. Objective This study aims to identify which barrier factors impede the usage of wearables for assessing individual risk scores for health insurances, despite its technological feasibility, and to rank these barriers according to their relevance. Methods To reach these goals, we conduct a ranking-type Delphi study with the following three stages. First, we collected possible barrier factors from a panel of 16 experts and consolidated them to a list of 11 barrier categories. Second, the panel was asked to rank them regarding their relevance. Third, to enhance the panel consensus, the ranking was revealed to the experts, who were then asked to re-rank the barriers. Results The results suggest that regulation is the most important barrier. Other relevant barriers are false or inaccurate measurements and application errors caused by the users. Additionally, insurers could lack the required technological competence to use the wearable data appropriately. Conclusion A wider use of wearables and health apps could be achieved through regulatory modifications, especially regarding privacy issues. Even after assuring stricter regulations, users' privacy concerns could partly remain, if the data exchange between wearables manufacturers, health app providers, and health insurers does not become more transparent.}, language = {en} } @article{Wegmann2022, author = {Wegmann, Simone}, title = {Policy-making power of opposition players}, series = {The Journal of Legislative Studies}, volume = {28}, journal = {The Journal of Legislative Studies}, number = {1}, publisher = {Routledge, Taylor \& Francis Group}, address = {Abingdon}, issn = {1357-2334}, doi = {10.1080/13572334.2020.1843233}, pages = {1 -- 25}, year = {2022}, abstract = {The organisation of legislative chambers and the consequences of parliamentary procedures have been among the most prominent research questions in legislative studies.

Thus, hospitals search for efficient opportunities to discover and integrate useful digital health innovations into their existing IT landscapes. In addition, although a multitude of digital innovations from digital health startups enter the market, numerous barriers impede their successful implementation and adoption. Against this background, the aim of this study was to explore typical digital innovation barriers in hospitals, and to assess how a hospital data management platform (HDMP) architecture might help hospitals to extract such innovative capabilities. Subject and methods Based on the concept of organizational ambidexterity (OA), we pursued a qualitative mixed-methods approach. First, we explored and consolidated innovation barriers through a systematic literature review, interviews with 20 startup representatives, and a focus group interview with a hospital IT team and the CEO of an HDMP provider. Finally, we conducted a case-study analysis of 36 digital health startups to explore and conceptualize the potential impact of DI and apply the morphological method to synthesize our findings from a multi-level perspective. Results We first provide a systematic and conceptual overview of typical barriers for digital innovation in hospitals. Hereupon, we explain how an HDMP might enable hospitals to mitigate such barriers and extract value from digital innovations at both individual and organizational level. Conclusion Our results imply that an HDMP can help hospitals to approach organizational ambidexterity through integrating and maintaining hundreds of systems and applications, which allows for a structured and controlled integration of external digital innovations.}, language = {en} } @article{Zhu2017, author = {Zhu, Jinshan}, title = {Assessing China's price review policy on Clean Development Mechanism projects}, series = {European Journal of Law and Economics}, volume = {43}, journal = {European Journal of Law and Economics}, publisher = {Springer}, address = {New York}, issn = {0929-1261}, doi = {10.1007/s10657-016-9550-3}, pages = {285 -- 316}, year = {2017}, abstract = {The Kyoto Protocol's Clean Development Mechanism (CDM) allows developed countries to meet part of their obligational emission reductions by carrying out emission reduction projects in developing countries.

This paper furthers the neoclassical perspective on land taxes by endogenizing land allocation decisions in a multi-sector growth model. Based on von Th{\"u}nen's observation, agricultural land is created from wilderness through conversion and cultivation, both of which are associated with costs. In the steady state of our general equilibrium model, land taxes not only may reduce land consumption (associated with environmental benefits) but may also affect overall economic output, while leaving wages and interest rates unaffected. When labor productivity is higher in the manufacturing than in the agricultural sector and agricultural and manufactured goods are substitutes (or the economy is open to world trade), land taxes increase aggregate economic output. There is a complex interplay of conservation policy, technological change and land taxes, depending on consumer preferences, sectoral labor productivities and openness-to-trade. Our model introduces a new perspective on land taxes in current policy debates on development, tax reforms as well as forest conservation.}, language = {en} } @article{PawassarTiberius2021, author = {Pawassar, Christian Matthias and Tiberius, Victor}, title = {Virtual reality in health care}, series = {JMIR Serious Games}, volume = {9}, journal = {JMIR Serious Games}, edition = {4}, publisher = {JMIR Publications}, address = {Toronto, Kanada}, issn = {2291-9279}, doi = {10.2196/32721}, pages = {1 -- 19}, year = {2021}, abstract = {Background: Research into the application of virtual reality technology in the health care sector has rapidly increased, resulting in a large body of research that is difficult to keep up with.

The decentralisation process has been utilised by ruling domestic elites for political purposes. Donors have rather focused on the technical side and ignored this informal dimension. By analysing the diverging objectives and perceptions of external and internal actors, as well as the instrumentalisation of formal democratic structures, it becomes clear, that the 'informal has to be seen as normal'. At a theoretical level, the analysis contributes to elite-oriented approaches of post-conflict democratisation by adding 'the informal' as an additional factor for the dynamics of external-internal interaction.
