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

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

Subjective cognitive complaints in schizophrenia:relation to antipsychotic medication dose, actual cognitive performance, insight and symptoms

Background: Subjective cognitive complaints are prevalent in those affected by functional psychoses and a variety of possible associated factors have been investigated. However, few studies have examined these potential factors within single studies or analyses. Methods: Patients with a history of a schizophrenia spectrum disorder (n = 115) and a non-clinical comparison group (n = 45) completed the Subjective Scale to Investigate Cognition in Schizophrenia (SSTICS) and the Brief Assessment of Cognition in Schizophrenia (BACS). The patient group also completed the Positive and Negative Syndromes Scale (PANSS), the Birchwood Insight Scale (IS), and the Hospital Anxiety and Depression Scale (HADS). Results: The BACS and SSTICS scores were associated in the non-clinical comparison group, but not in the patient group. In the patient group worse subjective cognition was associated positively with good insight, greater dysphoria and greater positive symptoms. Linear regression revealed that, once other variables had been accounted for, dysphoria (HADS anxiety and depression factor) was the only significant predictor of SSTICS scores. Conclusions: Subjective cognitive impairment in patients with psychosis in the absence of formal testing should not be taken as evidence of impaired cognitive functioning. Mood should be investigated when patients present with subjective cognitive complaints
