The thre­at of in­s­er­ting hard­ware Tro­jans du­ring the de­sign, pro­duc­tion, or in-field poses a dan­ger for in­te­gra­ted cir­cuits in re­al-world ap­p­li­ca­ti­ons. A par­ti­cu­lar cri­ti­cal case of hard­ware Tro­jans is the ma­li­cious ma­ni­pu­la­ti­on of third-par­ty FPGA con­fi­gu­ra­ti­ons. In ad­di­ti­on to at­tack vec­tors du­ring the de­sign pro­cess, FPGAs can be in­fil­tra­ted in a non-in­va­si­ve man­ner after ship­ment through al­te­ra­ti­ons of the bit­stream. First, we pre­sent an im­pro­ved me­tho­do­lo­gy for bit­stream file for­mat re­ver­sing. Se­cond, we in­tro­du­ce a novel idea for Tro­jan in­s­er­ti­on.

This paper presents an analytical framework of the product take back legislation in the context of product reuse. We characterize existing and proposed forms of E-waste legislation and compare their environmental and economic performance. Using stylized models, we analyze an OEM’s decision about new and remanufactured product quantity in response to the legislative mechanism. We focus on the 2012 waste electrical and electronic equipment directive in Europe, where the policy-makers intended to create additional incentives for the product reuse. Through a comparison to the original 2002 version of the directive, we find that these incentives translate into improved environmental outcomes only for a limited set of products. We also study a proposed policy that advocates a separate target for the product reuse. Our analysis reveals that from an environmental standpoint, the recast version is always dominated either by the original policy or by the one that advocates a separate target for the product reuse. We show that the benefits of a separate reuse target scheme can be fully replicated with the aid of fiscal levers. Our main message is that there can not be a single best environmental policy that is suitable for all products. Therefore, the consideration of product attributes is essential in identification of the most appropriate policy tool. This can be done either by the implementation of different policies on each product category or by implementation of product based target levels.

Crowdfunding has gained traction as a mechanism to raise resources for entrepreneurial and artistic projects, yet there is little systematic evidence on the potential of crowdfunding for scientific research. We first briefly review prior research on crowdfunding and give an overview of dedicated platforms for crowdfunding research. We then analyze data from over 700 campaigns on the largest dedicated platform, Experiment.com. Our descriptive analysis provides insights regarding the creators seeking funding, the projects they are seeking funding for, and the campaigns themselves. We then examine how these characteristics relate to fundraising success. The findings highlight important differences between crowdfunding and traditional funding mechanisms for research, including high use by students and other junior investigators but also relatively small project size. Students and junior investigators are more likely to succeed than senior scientists, and women have higher success rates than men. Conventional signals of quality–including scientists’ prior publications–have little relationship with funding success, suggesting that the crowd may apply different decision criteria than traditional funding agencies. Our results highlight significant opportunities for crowdfunding in the context of science while also pointing towards unique challenges. We relate our findings to research on the economics of science and on crowdfunding, and we discuss connections with other emerging mechanisms to involve the public in scientific research.

In recent years, the German banking sector has overcome major challenges such as the global financial crisis and the European debt crisis. This paper analyses a recent development as a particular determinant of the future outlook for the German banking sector. Interest rates are at historically low levels and may remain at these levels for a considerable period of time. Such levels pose a specific challenge to banks which are heavily dependent on interest income, as is the case for most German banks. We consider different interest rate scenarios and analyse the extent to which they cause a further narrowing of the interest rate margin. Our results indicate that a projected decline in this margin will result in no more than 20% of German banks earning a cost of capital of 8% by the end of this decade. This decline is somewhat alleviated by the fact that German banks can apply a special feature of German accounting standards by using hidden and open reserves.

The case tells a story of young European female manager joining a start-up operating in South-East Asia and facing challenges in adjusting to the work and life in a new environment. The protagonist finds it difficult to cope with a work situation where self-imposed expectations of excellence are difficult to achieve and with a life situation where social support is missing. The case culminates in the protagonist’s breakdown in an office meeting due to perceived failure to deliver on work tasks and to meet the expectations of the boss she respects and admires.

This book is a collection of challenging cases in executive coaching from the annals of the ESMT-Berlin Coaching Colloquia - yearly events for experienced professionals committed to advancement of the coaching profession. In the period of 2009-2018, hundreds of difficult cases were discussed by coaches from all over the world in an intensive but safe environment of the ESMT Berlin Campus. This volume presents a few of those cases to the interested public and offers a unique opportunity to explore the work of coaches from within and to reflect upon ways professionals approach ambiguous moments in their practice. The cases do not serve the purpose to endorse or critique a particular coaching choice, but rather give the reader an opportunity to think about their own ways of handling professional challenges in coaching engagements. The book can be an exciting self-development tool or instructional material for courses in coaching training or supervision.

In personal selling, the inspirational appeal (IA) is a widely promoted tactic that aims at stimulating customers’ values and ideals, thereby evoking emotions and arousing their enthusiasm for a product. However, whether IAs in fact improve or undermine salespeople’s success in sales talks remains controversial. Therefore, the present study examines consequences and key contingencies of IAs in customer–salesperson interactions in a retailing context, using multi-source data from several retailing industries for three quantitative studies, comprising a total sample of 590 customer and 174 salesperson responses. Drawing on the Multiple Inferences Model (MIM), the authors show that an IA is likely to drive the customer’s inference that the salesperson holds ulterior motives. IAs seem to be particularly detrimental for salespeople with a lack of customer orientation. Beyond expanding research on influence tactics and the ambivalent role of IAs in retailing interactions, these findings can guide practitioners about when to refrain from using an IA.

We examine whether start-ups attract employees with different pecuniary and non-pecuniary motives than small or large established firms. We then explore whether such differences in employee motives may lead to differences in innovative performance across firm types. Using data on more than 10,000 U.S. R&D employees, we find that start-up employees (“joiners”) place lower importance on job security and salary but greater importance on independence and responsibility. Start-up employees have higher patent output than employees in small and large established firms, and this difference is partly mediated by employee motives - especially joiners’ greater willingness to bear risk. We discuss implications for research as well as for managers and policy makers concerned with the supply of human capital to entrepreneurship and innovation.
