We analyze sibilant harmony in the Santiago Atitlán dialect of Tz’utujil (Mayan), a phenomenon that was briefly described by Dayley (1985). Novel data show that the obligatory harmony process (i) is asymmetrical (triggered only by [+ant] sibilants), (ii) progressive, and (iii) applies long-distance. Furthermore, we argue that the process is not stem-controlled. In contextualizing the phenomenon within the typology of sibilant harmony (Hansson 2010), we conclude that it is unique. Finally, we suggest that Santiago Tz’utujil sibilant harmony has been stable diachronically because the target segment /ʃ/ is always in the stressed syllable, thus being salient in the input during acquisition.

Harmonic Grammar

Positional Licensing constraints can compel a feature to spread to a prominent position such as a stressed syllable.  In Harmonic Grammar, this spreading takes a pathological form: over long distances, spreading can be blocked because it would accumulate too many faithfulness violations.  The result is an unattested system in which there is an arbitrary upper bound to the distance across which a feature can spread.  This defect is remedied here by modifying Positional Licensing so that rather than simply assigning one violation for an unlicensed feature, it assigns violations in proportion to the distance between the feature and its licensor.  It can therefore counter faithfulness regardless of the distance between trigger and target.  This reformulation necessitates other changes to avoid new problems: Positional Licensing must reward licensed features instead of penalizing unlicensed ones, and it must be couched in Serial Harmonic Grammar.  This result provides new support for those theoretical constructs, and it helps clarify the differences between OT and HG.

Distance Transport

Long distance transport in plants takes place in phloem tissue which has characteristic cells, the sieve elements. At maturity these cells have sieve areas in their end walls with specialized perforations. They are associated with companion cells, parenchyma cells, and in some species, with transfer cells. The protoplast of the functioning sieve element contains a high concentration of sugar, and consequently a high hydrostatic pressure, which makes it extremely difficult to fix mature sieve elements for electron microscopical observation without the formation of surge artifacts. Despite many structural studies which have attempted to prevent surge artifacts, several features of mature sieve elements, such as the distribution of P-protein and the nature of the contents of the sieve area pores, remain controversial.

Atherosclerotic Risk Factors

On the occasion of diagnosing a popliteal entrapment syndrome in a 59-year old man with no cardiovascular risk factors, who developed acute ischemic leg pain during long distance running, we give an overview on this entity with emphasis on patients’age. The different types of the popliteal artery compression syndrome are summarized. The diagnostic and therapeutic approaches are discussed. The most important clinical sign of a popliteal entrapment syndrome is the lack of atherosclerotic risk factors in patients with limited walking distance. Not only in young athletes but also in patients more than 50 years old the popliteal entrapment syndrome has to be taken into account.

This study aimed to explore the relationships between attachment styles, proximity, and relational satisfaction. This was achieved by assessing a distinct type of long distance romantic relationship of flying crews, compared with proximal (non-flying crew) romantic relationships. The responses of 139 expatriate professionals revealed significant associations between proximity and anxious and avoidant attachment dimensions. The role of the avoidant dimension in comparison with that of the anxious dimension was found to be a significant predictor of relational satisfaction. This study contributes significantly toward addressing the role of proximity and attachment in relational satisfaction in a new context of geographic separation.
