Description
Extensive cross-linguistic data document a wide gamut of semantic and pragmatic uses of the diminutive that revolve around the fundamental concepts of `small' and `child'. As typical inventory of informal registers, diminutives are utilized as pragmatic markers of politeness in a wide range of contextual meanings. This dissertation is intended to fill some major gaps in the systematic and empirical research on the formation and pragmatic uses of the diminutives in Macedonian and to explore the role of diminutivization in a broader linguistic framework, by examining the consistency of the field of diminutives, the core and peripheral meanings of the diminutive, their typology, as well as their pragmatic potential. The morphology and pragmatics of the diminutive is examined by combining data from electronic and printed sources, video recordings of natural conversations, as well as from material collected from participant and non-participant observations. At the level of morphology, it is argued that three fundamental semantic constraints underlie the formation of diminutives: [-big], [+ emotional], and [+ informal]. Furthermore, it is shown how diminutive combinability is rule governed in Macedonian by proposing sets of formal constraints for all grades of diminutives. At the level of pragmatics, the pragmatic functions of the diminutives proper and the related periphrastic diminutive malku are investigated in a variety of contexts involving child-directed speech (CDS) and adult communication. By analyzing the pragmatic functions of the diminutive in a series of speech acts, and drawing upon cross-cultural interpretations suggested by Wierzbicka (1991), it is argued that, in Macedonian, social bonding, cordiality, intimacy or affection are pragmatically more salient than personal autonomy in the Anglo-Saxon societies, realized through non-imposition, tentativeness, or similar pragmatic strategies for saving face. Additionally, it is contended that there exist cultural differences in the assessment of the concept of imposition between these societies. The analyses of the pragmatic potential of the diminutive proper and the periphrastic diminutive 'malku' give rise to the claim that Macedonian culture is predominantly founded on the pragmatic principle of positive politeness.

Description
Batrachochytrium dendrobatidis (Bd), the amphibian chytrid fungus causing chytridiomycosis, is the cause of massive amphibian die-offs. As with any host-pathogen relationship, it is paramount to understand the growth and reproduction of the pathogen that causes an infectious disease outbreak. The life-cycle of the pathogen, Bd, is strongly influenced by temperature; however, previous research has focused on Bd isolated from limited geographic ranges, and may not be representative of Bd on a global scale. My research examines the relationship between Bd and temperature on the global level to determine the actual thermal maximum of Bd. Six isolates of Bd, from three continents, were incubated at a temperature within the thermal range (21°C) and a temperature higher than the optimal thermal range (27°C). Temperature affected the growth and zoosporangium size of all six isolates of Bd. All six isolates had proliferative growth at 21°C, but at 27°C the amount and quality of growth varied per isolate. My results demonstrate that each Bd isolate has a different response to temperature, and the thermal maximum for growth varies with each isolate. Further understanding of the difference in isolate response to temperature can lead to a better understanding of Bd pathogen dynamics, as well as allow us the ability to identify susceptible hosts and environments before an outbreak.

Description
The amphibian chytrid fungus Batrachochytrium dendrobatidis (Bd) has captured human attention because it is a pathogen that has contributed to global amphibian declines. Despite increased research, much is still unknown about how it develops. For example, the fact that Bd exhibits phenotypic plasticity during development was only recently identified. In this thesis, the causes of phenotypic plasticity in Bd are tested by exposing the fungus to different substrates, including powdered frog skin and keratin, which seems to play an important role in the fungus's colonization of amphibian epidermis. A novel swelling structure emerging from Bd germlings developed when exposed to keratin and frog skin. This swelling has not been observed in Bd grown in laboratory cultures before, and it is possible that it is analogous to the germ tube Bd develops in vivo. Growth of the swelling suggests that keratin plays a role in the phenotypic plasticity expressed by Bd.
