New Firm Growth: Exploring Processes and Paths

This paper provides a new methodology for the diachronic study of new firm growth, theoretically grounded in the work of Penrose (1995). We show that a model of firm growth as an unfolding process makes possible draw simple, measurable inferences from firm level to aggregate evidence on growth paths of new firms, expressed as propositions. Metrics on growth paths of new firms in three longitudinal samples of new firms are examined for evidence at the aggregate level consistent with the dynamic model. Dynamic processes in the early development of young firms result in variations in the timing, magnitude, duration and rate of change of growth as between firms and in the same firm over time. The conceptual and methodological framework in this paper provides a basis for future research aimed at explaining the development of new firms.entrepreneurship;Penrose;growth paths;new firm growth;resource-based perspective

Martian impact basins: Morphology differences and tectonic provinces

Detailed geomorphic and structural mapping of five Martian basins and preliminary study of eleven other basins reveal four characteristic styles of modification that relate to the degree and age of past tectonic activity. Within regions that exhibit no evidence for tectonic activity, the modification style can be used to distinguish areas dominated by different exogenic processes. A framework for understanding these different styles of basin modification is provided

Апробация программно-технологического инструментария автоматизации имитационного моделирования процессов предоставления услуг

Приведены результаты апробации программно–технологического инструментария процессов предоставления услуг, полученные во время его внедрения в работу двух отделений связи г. Гомеля. Описана методика анализа качества предоставления услуг, которая легко распространяется на другие проблемне области. На конкретном примере рассмотрена технология системного анализа динамики изменения «узких мест» в ходе имитационного эксперимента, позволяющая исследовать сложные процессы в условиях, значительно отличающихся от существующей практики организации работы отделений связи.Наведено результати апробації програмно-технологічного інструментарію надання послуг, отримані під час його впровадження у роботу двох відділень зв’язку м. Гомеля. Описано методику аналіза якості надання послуг, яка розповсюджується на інші проблемні сфери. На конкретному прикладі розглянуто технологію системного аналізу динаміки зміни «вузьких місць» у процесі імітаційного експерименту, яка дозволяє досліджувати складні процеси в умовах, що значною мірою відрізняються від наявної практики організації роботи відділень зв’язку.The results of the trial of program and technological tools for automation of service process simulation obtained via applying them to the operation of two Homel regional post offices are discussed. Methods for analysis of the quality of postal services are described. They are spread trivially over other problem areas. Technology of the system analysis of the “bottlenecks” change in the course of simulation experiment is considered. It permits one to study complicated processes under conditions markedly different from the conventional operation of post offices

Scattering matrices and expansion coefficients of Martian analogue palagonite particles

We present measurements of ratios of elements of the scattering matrix of Martian analogue palagonite particles for scattering angles ranging from 3 to 174 degrees and a wavelength of 632.8 nm. To facilitate the use of these measurements in radiative transfer calculations we have devised a method that enables us to obtain, from these measurements, a normalized synthetic scattering matrix covering the complete scattering angle range from 0 to 180 degrees. Our method is based on employing the coefficients of the expansions of scattering matrix elements into generalized spherical functions. The synthetic scattering matrix elements and/or the expansion coefficients obtained in this way, can be used to include multiple scattering by these irregularly shaped particles in (polarized) radiative transfer calculations, such as calculations of sunlight that is scattered in the dusty Martian atmosphere.Comment: 34 pages 7 figures 1 tabl

The (un)making of Dutch ‘care girls’: An ethnographic study on aspirations, internship experiences and labour market perspectives

In this study, we focus on the role of Dutch Level 2 senior vocational training in care work in relation to the prospects and options it provides for students who follow this programme. Similar to the ‘care girls’ from previous studies our participants are young women from lower-class backgrounds who aspire to various jobs in the care sector, but are steered away from their original aspirations by their vocational training programme. The major difference between this research and previous studies is that we examine the Dutch institutional and broader structural context of care work. In the Netherlan

A grid of polarization models for Rayleigh scattering planetary atmospheres

We investigate the intensity and polarization of reflected light from planetary atmospheres. We present a large grid of Monte Carlo simulations for planets with Rayleigh scattering atmospheres. We discuss the disk-integrated polarization for phase angles typical of extrasolar planet observations and for the limb polarization effect observable for solar system objects near opposition. The main parameters investigated are single scattering albedo, optical depth of the scattering layer, and albedo of an underlying Lambert surface for a homogeneous Rayleigh scattering atmosphere. We also investigate atmospheres with isotropic scattering and forward scattering aerosol particles, as well as models with two scattering layers. The model grid provides a tool for extracting quantitative results from polarimetric measurements of planetary atmospheres from solar system planets and extrasolar planets, in particular on the scattering properties and stratification of particles in the highest atmosphere layers. Spectropolarimetry of solar system planets offers complementary information to spectroscopy and polarization flux colors can be used for a first characterization of exoplanet atmospheres. From limb polarization measurements, one can set constraints on the polarization at large phase angles.Comment: 19 pages, 21 figures. Minor changes. Published in Astronomy and Astrophysic

How does learning drive sustainability transitions?: Perspectives, problems and prospects from a systematic literature review

Learning has been put forward as a critical aspect to achieve sustainable transformation of societal systems. However, there is a lack of a systematic review of empirical evidence on how learning is related to sustainability transitions. To bridge this gap, we systematically reviewed 113 empirical papers that addressed the role of learning in transitions. Our results show that the complexity of the relationship between learning and transitions is not deeply analysed and that there is a need to distinguish more precisely between learning processes and learning outcomes. Further, there is a need to shift the focus towards analysing regime-level learning to increase our understanding of how learning contributes to system transformation. Finally, networks, trust, disagreement, and power are key aspects related to learning that will require further examination, especially in terms of how they play out dynamically in learning for sustainability transitions
