  Cancer care is expensive. Cancer care provided by practice organizations varies in total spending incurred by patients and payers during treatment episodes and in quality of care, and this unnecessary variation contributes to the high cost.To use the variation in total spending and quality of care to assess oncology practice attributes distinguishing “high value” that may be tested and adopted by others to produce similar results.“Positive deviance” was used in this exploratory mixed-methods (quantitative and qualitative) analysis of interview results. To quantify value, oncology practices located near the US Pacific Northwest and Midwest with low mean insurer-allowed spending were identified. Among those, practices with high quality were selected. A team then conducted site visits to interview practice personnel from June 2, 2015, through October 3, 2015, and to probe for attributes of high-value care. A qualitative analysis of their interview results was performed, and a panel of experienced oncologists was convened to review attributes occurring uniquely or frequently in low-spending practices for their contribution to value improvement and ease of implementation. Four positive deviant (ie, low-spending) oncology practices and 3 oncology practices that ranked near the middle of the spending distribution were studied.Thematic saturation in a qualitative analysis of high-value care attributes.From the 7 oncology practices studied, 13 attributes within the following 5 themes emerged: treatment planning and goal setting, services supporting the patient journey, technical support and physical layout, care team organization and function, and external context. Five attributes (ie, conservative use of imaging, early discussion of treatment limitations and consequences, single point of contact, maximal use of registered nurses for interventions, and a multicomponent health care system) most sharply distinguished the high-value practice sites. The expert oncologist panel judged 3 attributes (ie, early and normalized palliative care, ambulatory rapid response, and early discussion of treatment limitations and consequences) to carry the highest immediate potential for lowering spending without compromising the quality of care.Oncology practice attributes warranting further testing were identified that may lower total spending for high-quality oncology care.

• Towards Emancipatory Aspects of Women’s Entrepreneurship: An Alternative Model of Women’s Entrepreneurial Self-Efficacy in Patriarchal Societies

  Mikkelsen, K. (2018). Towards Emancipatory Aspects of Women’s Entrepreneurship: An Alternative Model of Women’s Entrepreneurial Self-Efficacy in Patriarchal Societies.

  This chapter considers societal gender mechanisms in an effort to shed light on the antecedents of women’s entrepreneurial self-efficacy (ESE). While numerous studies have repeatedly assessed the relevance of ESE for developing entrepreneurial intentions, making clear that women tend to express significantly lower levels of ESE, there are hardly any contributions dealing with the antecedents of ESE. Social mechanisms resulting from national cultural attitudes appear significant when it comes to this topic. By integrating gender as a category into this investigation, a major focus lies upon the analysis of societal processes of doing gender and its effect on the construction of women’s ESE. A better understanding of this construction process is an important step towards a more gender-sensitive entrepreneurial ecosystem that supports women. The following investigation of German and Danish women entrepreneurs showed that despite a higher rate of gender egalitarianism in their country, Danish women face obstacles similar to those found in Germany on their path towards becoming self-employed. In addition, founding their own business appears to be the result of an overall emancipatory process. The relation between societal processes and the construction of ESE is presented in the model of entrepreneurial self-efficacy in patriarchal structures.

• Existenzgründung von Frauen im Care-Bereich – Effekte von Arbeitszeit, Arbeitsform und Einkommen auf die Arbeits- und Lebenszufriedenheit

  Ebbers, I., Mikkelsen, K., & Piper, A. (2018). Existenzgründung von Frauen im Care-Bereich – Effekte von Arbeitszeit, Arbeitsform und Einkommen auf die Arbeits- und Lebenszufriedenheit.

  Der Anteil von Unternehmensgründungen von Frauen im Gesundheitssektor ist in Relation zu anderen Branchen mit ca. 48 % relativ hoch. Es darf vermutet werden, dass ein Grund hierfür in dem ohnehin hohen Beschäftigungsanteil von Frauen in diesem Sektor liegt, welcher 87 % beträgt. Es darf jedoch auch angenommen werden, dass die Entscheidung für eine Gründung darin bestehen könnte, eine persönliche Verbesserung der Erwerbsarbeit zu erlangen. Diese Annahme führt zu der Frage, ob unternehmerisch selbstständige Frauen im Gesundheitssektor zufriedener mit ihrer Arbeits- und Lebenssituation sind als angestellt erwerbstätige Frauen. Auch interessiert die Frage vor dem Hintergrund eines Geschlechtervergleichs. Es wurden diesbezüglich Daten zu Arbeitszeit, Arbeitsform und Einkommen erhoben und deren Effekte auf Job- und Lebenszufriedenheit analysiert sowie abschließend diskutiert.

• A sustainable aggregate production planning model for the chemical process industry

  Hahn, G. J., & Brandenburg, M. (2018). A sustainable aggregate production planning model for the chemical process industry. Computers & Operations Research, 94, 154–168. http://doi.org/10.1016/j.cor.2017.12.011

  Abstract

  Process industries typically involve complex manufacturing operations and thus require adequate decision support for aggregate production planning (APP). In this paper, we focus on two relevant features of APP in process industry operations: (i) sustainable operations planning involving multiple alternative production modes/routings with specific production-related carbon emission and the social dimension of varying operating rates, (ii) integrated campaign planning with the operational level in order to anticipate production mix/volume/routing decisions on campaign lead times and WIP inventories as well as the impact of variability originating from a stochastic manufacturing environment. We focus on the issue of multi-level chemical production processes and highlight the mutual trade-offs along the triple bottom line concerning economic, environmental and social factors. To this end, production-related carbon emission and overtime working hours are considered as externalized factors as well as internalized ones in terms of resulting costs. A hierarchical decision support tool is presented that combines a deterministic linear programming model and an aggregate stochastic queuing network model. The approach is exemplified at a case example from the chemical industry to illustrate managerial insights and methodological benefits of our approach.

• Information Push and Pull in Tactile Pedestrian Navigation Support

  von Jan, V., Bertel, S., & Hornecker, E. (2018). Information Push and Pull in Tactile Pedestrian Navigation Support. In Proceedings of the 20th International Conference on Human-Computer Interaction with Mobile Devices and Services Adjunct (S. 55–62).

  For pedestrian navigation support, we report on how the feeling of being in control about receiving updates impacts navigation efficiency and user experience. In an exploratory field study, 24 participants navigated to previously unknown targets using a wristband which conveyed tactile information about targets bearing. Information was either pulled by the user at times of her choosing via a simple arm gesture, or was pushed by the armband at a regular, preset interval. While the push mode resulted in higher efficiency, more users preferred actively pulling information, possibly as this afforded feeling more in control. Interestingly, mode preference was independent of individual navigation ability. Results suggest that properties of the specific navigation context should be used to determine whether an interface offers push or pull modes for navigation support.
