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

Strength, gender, and volunteering: the lived experiences of Para-powerlifters in the Republic of Ireland

This study provides the first meaningful examination of para-powerlifting in Ireland. A sport practiced around the world, para-powerlifting has not yet received a great deal of academic attention despite research done in related fields such as wheelchair bodybuilding (Sparkes, Brighton, and Inckle 2018). Irish para-powerlifting is distinguished by the fact that the competitors are women operating in a hyper-masculine space. Semi-structured interviews were conducted with athletes, coaches, parents and former volunteers. Interviews revealed the following: (i) athletes face material and ideological barriers to participation; (ii) entrance pathways stemmed predominantly from wheelchair basketball (iii) para-powerlifting had a beneficial crossover in athletes’ daily lives (iv) participation changed athletes’ relationships with their own bodies and (v) gender played a key role in staying in, or leaving, the sport. We conclude that while para-powerlifting is not unique in suffering from a lack of resources, efforts to maintain and increase female participation help to subvert traditional masculine tropes within this sport For policymakers, para-powerlifting simultaneously highlights the need to take seriously accessibility in Ireland while also offering an opportunity to invest in a sport with the potential to earn medals in competition.</p

Oyster (Crassostrea virginica) Mortality Studies Along the Texas Coast

Mortality rates among oysters (Crassostrea virginica) of different sizes and from different bay areas were compared in three separate studies in Galveston, Matagorda, and Aransas Bays. A general pattern of spring and late summer mortality cycles was observed in Galveston and Aransas Bays with higher mortalities occurring in late summer. An unusual fall (November) mortality period was observed in Matagorda Bay. Dermocystidium appeared to be the major cause of mortality among oyster stocks in Galveston Bay but was not responsible for the extreme mortalities in Matagorda and Aransas Bays. The presence of Aransas Bay Organisms (ABO) in these areas was suspected but not confirmed

The Psychological Assessment of Language: A Philosophical Critique of the Illinois Test of Psycholinguistic Abilities.

It is argued in this paper that the Illinois Test of Psycholinguistic\ud Abilities (ITPA), a test widely used in the assessment\ud of certain language abilities in children, does not measure what it\ud purports to measure; in psychometric terminology, it does not have\ud construct validity. Specifically it is contended that the inferences\ud concerning the processing of language which are made on the basis of\ud children's performance on the tasks of the test are not warranted.\ud Three competing versions of the intended inferences are characterized •\ud at the outset of the paper, with particular attention being paid to\ud the logical relations obtaining between a given inference and the\ud test performance on which it is based. Central among these competing\ud interpretations is that wherein the psycholinguistic processes\ud postulated by Charles E. Osgood in his mediational response (neobehaviorist)\ud theory of communication are taken to be under assessment.\ud Considerable attention and criticism is brought to bear on Osgood's\ud theory because of the central role it played in the development of\ud the ITPA and because, at least on one interpretation of the test,\ud the processes specified by him are under assessment. The latter\ud interpretation is rejected on the grounds that Osgoodian theory is\ud incorrect, vitiated by an equivocation on his central theoretical\ud construct. The two other interpretations of the test, which do not\ud depend upon the correctness of Osgood's theory for their own validity,\ud are challenged and rejected independently. The conclusion reached\ud is that under none of the adopted formulations, all of which are\ud supported by the ITPA literature and have adherents amono the test's\ud many commentators, does the ITPA succeed in providing the information\ud about children's processinc of language which-it purports to provide.\ud The manifest consequences for educational decisions and programs\ud predicated on the belief that the test doeS do so are noted
