In the simulation ZUG UM ZUG 2015, participants form union and management negotiation teams to negotiate with each other (first level) and with a management or union “tariff commission,” which has to approve proposed contracts (second level). To increase the degree of realism and the teaching effectiveness of the simulation, real-world negotiation experts negotiate in tariff commissions directly with participants. The authors also introduce a negotiation process to facilitate an efficient knowledge transfer from experts to learners

Plasma and CSF NfL are differentially associated with biomarker evidence of neurodegeneration in a community-based sample of 70-year-olds.

Neurofilament light protein (NfL) in cerebrospinal fluid (CSF) and plasma (P) are suggested to be interchangeable markers of neurodegeneration. However, evidence is scarce from community-based samples. NfL was examined in a small-scale sample of 287 individuals from the Gothenburg H70 Birth cohort 1944 study, using linear models in relation to CSF and magnetic resonance imaging (MRI) biomarker evidence of neurodegeneration. CSF-NfL and P-NfL present distinct associations with biomarker evidence of Alzheimer's disease (AD) pathology and neurodegeneration. P-NfL was associated with several markers that are characteristic of AD, including smaller hippocampal volumes, amyloid beta (Aβ)42, Aβ42/40, and Aβ42/t-tau (total tau). CSF-NfL demonstrated associations with measures of synaptic and neurodegeneration, including t-tau, phosphorylated tau (p-tau), and neurogranin. Our findings suggest that P-NfL and CSF-NfL may exert different effects on markers of neurodegeneration in a small-scale community-based sample of 70-year-olds

Ontogeny of domestic dogs and the developmental foundations of carnivoran domestication

Whereas hundreds of breeds of domestic dogs are known, only several dozen domestic cat breeds are currently recognized, and the ferret is not classified into specific breeds. We studied pre- and postnatal patterns of development and growth in the domesticated forms of these three carnivoran species. We present the most comprehensive staging system for domestic dog embryos to date and define qualitative characters for phylogenetic comparisons. For postnatal development, we present analyses of new and literature measurements of cranial and limb proportions. We analyze changes in the progress of growth among different domestic dog and domestic cat breeds. All three domesticated forms drastically differ in the relative timing of prenatal development. This is correlated with ontogenetic plasticity at birth, which enables artificial selection to act. For postnatal development, we detected a greater shape variance in domestic dog ontogeny when compared to that of the domestic cat. We conclude that ontogenetic preconditions as well as body size constrain the species’ capability for artificial selection in domestic dogs and cats. However, we speculate that the human requirements for functional performance of their domesticates might render some developmental biases substantially. Although ferrets would be preferable for artificial selection given their plastic embryonic development, they have been of less interest for domestication due to their small body size - by which they were already well adapted for hunting in burrows - and due to the fact that other relevant tasks were already assumed by domestic cats and dogs since earlier phases of human cultural evolution

Value-based pricing in competitive situations with the help of multi-product price response maps

This article introduces multi-product price response maps for various value pricing applications in competitive situations. The maps are based on the direct elicitation of individual willingness to pay (WTP) as a range for competing products; they reveal an individual's or market's choice probability for a focal product, at its own and competing products' prices. Transforming the price response into profit, revenue, or unit sold maps supports optimal pricing decisions. The maps are also useful for optimizing profit differences from the closest competitor and for portfolio pricing. Managers can use a consumer indecisiveness map, gained from the WTP range data, to devise complementary marketing measures at prices where consumer uncertainty is high. The illustration of this approach uses two empirical examples, featuring two or more competing consumer goods, and demonstrates the predictive and external validity of these proposed maps

Situational strategic versus personal influences on negotiation medium choice

Purpose This study aims to compare predictions from media synchronicity theory (MST) with the influence of personality variables in an attempt to explain how negotiators choose the communication media for negotiation. Design/methodology/approach The authors examine media choice in two scenario-based experimental studies with students (n = 209) and professionals (n = 302) in a negotiation setting. For the analysis of the data, the authors use multilevel modeling. Findings This study offers support for the central proposition of MST, namely, that the type of communication subtask (conveyance or convergence) determines the degree of media synchronicity needed and therefore media choice (face-to-face or email). The support for its boundary conditions and contingent situational determinants is weaker. With the affect for communication channel scale, this study also captures individual media preferences for face-to-face or email communication, which have consistent influences on negotiators’ media choice. The personal influence variables on average account for similar variance in the data compared with the MST-based determinants. Originality/value This study sheds new light on diverging empirical results concerning media influences in negotiation and offers some reconciling suggestions. Furthermore, this study is the first to test boundary conditions of MST. Also, it stresses the importance of negotiators’ media preferences for media choice. </jats:sec
