Abstract Purpose: Frontotemporal lobar degeneration (FTLD) encompasses a group of neurodegenerative disorders characterized by gradual and progressive decline in behavior and/or language. Identifying the subtypes of FTLD can be challenging with traditional assessment tools. Growing empirical evidence suggests that language measures might be useful in differentiating FTLD subtypes. Method: In this paper, we examined the performance of five individuals with FTLD (two with frontotemporal dementia, two with semantic dementia, and one with progressive nonfluent aphasia) and 10 cognitively normal older adults on measures of semantic binding (Semantic Object Retrieval Test and semantic problem solving) and abstracted meaning (generation of interpretive statement and proverb interpretation). Results and Conclusion: A differential profile of impairment was observed in the three FTLD subtypes on these four measures. Further examination of these measures in larger groups will establish their clinical utility in differentiating the FTLD subtypes.

This article aims to confront four theories of firm growth – Optimum Firm Size, Stage Theory of Growth, The Theory of the Growth of the Firm and Dynamic Capabilities – with empirical data derived from a backward-looking longitudinal qualitative case of the growth trajectory of a Brazilian capital goods firm. To do so, we employed Degree of Freedom-Analysis for data analysis. This technique aims to test the empirical strengths of competing theories using statistical tests, in particular Chi-square test. Our results suggest that none of the four theories fully explained the growth of the firm we chose as empirical case. Nevertheless, Dynamic Capabilities was regarded as providing a more satisfactory explanatory power.

The purpose of this constructivist grounded theory article is to identify, explore, and theorize the social and psychological processes used by people with Parkinson disease. Analytic procedures generated the five-stage theory of Preserving self of people with Parkinson disease: (a) making sense of symptoms, (b) defining turning points, (c) experiencing identity dilemmas, (d) reconnecting the self, and (e) envisioning a future. Reminders of former selves and capabilities were painful; participants desperately sought normalcy. Participants developed creative methods for maintaining independence but frequently overestimated their abilities and took risks. Participants were 15 men and 10 women (ages 40–95), most of whom lived with their families. Disease status was ascertained through medication logs and two scales: Hoehn and Yahr staging and Activities of Daily Living. Data included 62 in-depth interviews, nonparticipant observation, and participant photos, videos, and related documents. Recommendations were derived from the theory to support processes of Preserving Self as interventions designed to reduce the loss of self and to enhance Preserving self. These recommendations included developing relationships, teaching expected and unexpected feelings and behaviors, and involvement with sensory integrating activities.

Over the last twenty-five years children around the world have observed and responded to researchers who pour water from beaker to beaker, roll plasticene into snake-like figures, and arrange matchsticks into a potpourri of shapes. These cross-cultural experiments have been undertaken to test Piaget's theory of genetic epistemology, which posits a hierarchical, universal, and invariant sequence of stages of cognitive development. Piagetian research in varying cultures has revealed both striking similarities and marked differences in performance on cognitive tasks, some in apparent conflict with the basic assumptions of Piagetian stage theory. In this article Professor Ashton reviews a range of cross-cultural Piagetian research, analyzes the sometimes divergent findings from this research, and suggests methodological improvements which may help to resolve past dilemmas and to further future understanding of cognitive growth in different cultures.
