The More Learning, the Better? The Curvilinear Relationship between Technological Learning and New Product Commercialization

Managers entrusted with new product development (NPD) have to seek the optimal balance between prior competencies and learning activities to generate successful products. Yet prior NPD research has largely taken a positivistic view of learning despite an inkling that too much learning can lead to dysfunction. This study attempts to contribute the NPD literature by analyzing whether and, if so, when technological learning engenders shortcomings and affects new product commercialization. We use a multi-informant longitudinal design combining unique survey and patent data on a multi-industry sample of about 163 product-based R&D collaborations in Germany. The results of a Cox regression reveal that prior technological knowledge is pervasively important for NPD and confirm that an inverted U-shaped relationship holds between the likelihood of commercialization and technological learning. The inverted U-shaped relationship supports the characterization of learning as a double-edged sword that helps overcome rigidities but also has downsides if taken too far. Exploitive learning, in particular, is the later of the two to incur downsides. This draws attention to the inherent uncertainty and costs of experimentation when learning is geared to exploration. As expected, technological progress determines NPD, but the influence is negligibly small. We argue that inertia dominates NPD projects, at least in the short-term. Our findings mainly contribute to the NPD literature by demonstrating a differentiated learning-performance relationship. The results reveal whether and, if so, when, learning can become a drag to NPC and traps may occur. Managers are advised to ensure, at least, a fit between project requirements and prior competencies, but also to ensure adequate learning. Irrespective whether learning is geared to exploration or exploitation, it is advisable to maintain it at an appropriate level. This article suggests a patent-based instrument to monitor and manage learning efforts

Was the fishing village of Lepenski Vir built by Europe’s first farmers?

It is now widely accepted that agriculture and settled village life arrived in Europe as a cultural package, carried by people migrating from Anatolia and the Aegean Basin. The putative fisher-forager site of Lepenski Vir in Serbia has long been acknowledged as an exception to this model. Here, the Mesolithic–Neolithic transition—possibly inspired by interaction with the new arrivals—was thought to have taken place autochthonously on site. Our reinterpretation, based on ancient genomes, as well as archaeological and isotopic evidence, indicates that here, too, house construction, early village society and agriculture were primarily associated with Europe’s first farmers, thus challenging the long-held view of Lepenski Vir as a Mesolithic community that adopted Neolithic practices. Although aspects of the site's occupation, such as the trapezoidal houses, were inspired by local Mesolithic traditions, it is far from certain that the village was founded by Iron Gates foragers. A detailed timeline of population changes at the site suggests that Aegean incomers did not simply integrate into an established Mesolithic society, but rather founded new lineages and households. Iron Gates foragers and their admixed descendants largely appear to have been buried separately, on the fringes of the settlement. The diet of those buried outside in pits shows no major shift from aquatic to terrestrial food resources

Remote Sensor for Spatial Measurements by Using Optical Scanning

In this paper, we propose a low-cost contact-free measurement system for both 3-D data acquisition and fast surface parameter registration by digitized points. Despite the fact that during the last decade several approaches for both contact-free measurement techniques aimed at carrying out object surface recognition and 3-D object recognition have been proposed, they often still require complex and expensive equipment. Therefore, alternative low cost solutions are in great demand. Here, two low-cost solutions to the above-mentioned problem are presented. These are two examples of practical applications of the novel passive optical scanning system presented in this paper

Ancient genomes provide insights into family structure and the heredity of social status in the early Bronze Age of southeastern Europe

Twenty-four palaeogenomes from Mokrin, a major Early Bronze Age necropolis in southeastern Europe, were sequenced to analyse kinship between individuals and to better understand prehistoric social organization. 15 investigated individuals were involved in genetic relationships of varying degrees. The Mokrin sample resembles a genetically unstructured population, suggesting that the community's social hierarchies were not accompanied by strict marriage barriers. We find evidence for female exogamy but no indications for strict patrilocality. Individual status differences at Mokrin, as indicated by grave goods, support the inference that females could inherit status, but could not transmit status to all their sons. We further show that sons had the possibility to acquire status during their lifetimes, but not necessarily to inherit it. Taken together, these findings suggest that Southeastern Europe in the Early Bronze Age had a significantly different family and social structure than Late Neolithic and Early Bronze Age societies of Central Europe

Screening archaeological bone for palaeogenetic and palaeoproteomic studies.

The recovery and analysis of ancient DNA and protein from archaeological bone is time-consuming and expensive to carry out, while it involves the partial or complete destruction of valuable or rare specimens. The fields of palaeogenetic and palaeoproteomic research would benefit greatly from techniques that can assess the molecular quality prior to sampling. To be relevant, such screening methods should be effective, minimally-destructive, and rapid. This study reports results based on spectroscopic (Fourier-transform infrared spectroscopy in attenuated total reflectance [FTIR-ATR]; n = 266), palaeoproteomic (collagen content; n = 226), and palaeogenetic (endogenous DNA content; n = 88) techniques. We establish thresholds for three different FTIR indices, a) the infrared splitting factor [IRSF] that assesses relative changes in bioapatite crystals' size and homogeneity; b) the carbonate-to-phosphate [C/P] ratio as a relative measure of carbonate content in bioapatite crystals; and c) the amide-to-phosphate ratio [Am/P] for assessing the relative organic content preserved in bone. These thresholds are both extremely reliable and easy to apply for the successful and rapid distinction between well- and poorly-preserved specimens. This is a milestone for choosing appropriate samples prior to genomic and collagen analyses, with important implications for biomolecular archaeology and palaeontology

Low Prevalence of Lactase Persistence in Bronze Age Europe Indicates Ongoing Strong Selection over the Last 3,000 Years

Lactase persistence (LP), the continued expression of lactase into adulthood, is the most strongly selected single gene trait over the last 10,000 years in multiple human populations. It has been posited that the primary allele causing LP among Eurasians, rs4988235-A [1], only rose to appreciable frequencies during the Bronze and Iron Ages [2, 3], long after humans started consuming milk from domesticated animals. This rapid rise has been attributed to an influx of people from the Pontic-Caspian steppe that began around 5,000 years ago [4, 5]. We investigate the spatiotemporal spread of LP through an analysis of 14 warriors from the Tollense Bronze Age battlefield in northern Germany (∼3,200 before present, BP), the oldest large-scale conflict site north of the Alps. Genetic data indicate that these individuals represent a single unstructured Central/Northern European population. We complemented these data with genotypes of 18 individuals from the Bronze Age site Mokrin in Serbia (∼4,100 to ∼3,700 BP) and 37 individuals from Eastern Europe and the Pontic-Caspian Steppe region, predating both Bronze Age sites (∼5,980 to ∼3,980 BP). We infer low LP in all three regions, i.e., in northern Germany and South-eastern and Eastern Europe, suggesting that the surge of rs4988235 in Central and Northern Europe was unlikely caused by Steppe expansions. We estimate a selection coefficient of 0.06 and conclude that the selection was ongoing in various parts of Europe over the last 3,000 years
