Online platforms not only serve to exchange information and goods but increasingly also service work provided by the self‐employed. The emergence of crowdsourcing of paid work has created a global market for online labour where services can be fully acquired and provided irrespective of location via platforms such as upwork.com or freelancer.com. Drawing on a content analysis of the websites of 44 globally operating platforms, this study has investigated the discursive construction of this new type of labour market. The findings show that platforms address the online workforce in different ways, for instance, as workers or freelancers. Contrary to their blanket characterisation as an anonymous crowd in previous academic debate, in most cases, online workers are forced to present themselves as talented experts to distinguish themselves from the mass of competitors. The control over online labour that these platforms exercise challenges existing conceptions of professionalism and self‐employment.

This paper presents the argument that we are witnessing a fundamental transformation in society’s disposition of labor capacity, seen in changes in the labor strategy of large employers. This may be leading to a new type of labor power that could be called ‘self-entrepreneurial’. In the paper’s first part the concept of the ‘entreployee’ (Arbeitskraftunternehmer) is presented briefly, after which, the second part examines several important theoretical objections to the concept, raised in the course of current German debate.

SUMMARY1. The effects of air humidity on respiratory rate have been studied in conscious goats exposed to an air temperature of + 33 'C. Before the experiments the animals had been chronically implanted with hypothalamic thermodes and intravascular heat exchangers to manipulate hypothalamic and general body core temperatures.2. Raising air humidity from 37 to 96% at constant air temperature resulted in a rise of respiratory rate, an immediate increase in hypothalamic temperature and a delayed smaller increase in general body core temperature.3. The rise cf respiratory rate was smaller when general body core temperature was clamped at its control level and was absent when hypothalamic and general body core temperatures were clamped at their control levels during the humid air phase.4. It is concluded that the effect of high air humidity on respiratory rate in goats is predominantly the result of a rise in hypothalamic temperature acting on local thermosensitive structures. The carotid rete heat exchanger is thought to provide the thermal link between the evaporating surfaces of the upper respiratory tract and the hypothalamus.5. This function of the carotid rete heat exchanger is restricted to heat stressed animals. In animals subject to central cooling no local effects on hypothalamic temperature could be observed when the temperature of the inspired air was altered from + 33 to -17 'C.

The development of agriculture in the past decades has been determined worldwide by modernization measures. Mechanization and intensificarion of production. rationalization of farm management and adaptation (0 urban-industrial lifestyles were the goals of modernization wh ich were also pursued by the various disciplioes of agricultural science. In so far as any attention at all was paid to farm people's cu lture, i.e. tbe totality of ways of life and rules of behaviour among the farming population (wh ich must be differentiated according to region), it was usually regarded as
