scholarly journals The Phylogenetic Status of Pacific Coast Athabaskan: A Computational Assessment

Justin Spence

In lieu of an abstract, here is a brief excerpt:The present study considers the status of the Pacific Coast Athabaskan languages, both in relation to each other and in relation to the rest of the family, by applying computational approaches to phylogenetic inference adapted from the biological sciences that have invigorated historical linguistic research over the past decade. These methods have shed light on previously intractable problems, and in some cases sparked new controversies, in language families as diverse as Indo-European (Gray and Atkinson 2003; Atkinson and Gray 2006; Nakhleh et al. 2005; Bouckaert et al. 2012), Bantu (Holden and Gray 2006, Marten 2006), Austronesian (Bryant 2006, Dunn et al. 2008), and Pama-Nyungan (Bowern and Atkinson 2012).

Earthquakes in the past few thousand years have left signs of land-level change, tsunamis, and shaking along the Pacific coast at the Cascadia subduction zone. Sudden lowering of land accounts for many of the buried marsh and forest soils at estuaries between southern British Columbia and northern California. Sand layers on some of these soils imply that tsunamis were triggered by some of the events that lowered the land. Liquefaction features show that inland shaking accompanied sudden coastal subsidence at the Washington-Oregon border about 300 years ago. The combined evidence for subsidence, tsunamis, and shaking shows that earthquakes of magnitude 8 or larger have occurred on the boundary between the overriding North America plate and the downgoing Juan de Fuca and Gorda plates. Intervals between the earthquakes are poorly known because of uncertainties about the number and ages of the earthquakes. Current estimates for individual intervals at specific coastal sites range from a few centuries to about one thousand years.

Microcotyle is one of the most diverse and controversial genera within the family Microcotylidae. To date, 131 species have been described in Microcotyle; however, more than half have been transferred to other genera, and several others have poor descriptions. Therefore, less than half of all Microcotyle species may be considered valid. In Chile, two species have been recognized, and unidentified Microcotyle have been found on several littoral fish, but there has been no effort to properly identify them. In this study, two new species of Microcotyle are taxonomically described from intertidal fish of the central (33°S) and south-central (36°S) regions of Chile. In this study, Microcotyle sprostonae n. sp. (collected mainly from Scartichthys viridis in central Chile) and M. chilensis n. sp. (collected mainly from Calliclinus geniguttatus in south-central Chile) were identified based on morphological and molecular analyses (ITS2 and 18S genes). Both species of Microcotyle principally differed from one another and from other valid species in the number of testes and clamps. The two new species also differed from one another by one base pair in the ITS2 and 18S genes and differed from other species of Microcotyle by several base pairs of both genes. Intertidal fish are mostly endemic to the Pacific coast of South America, and they have a limited geographical distribution that does not overlap with the type hosts of other Microcotyle species. Therefore, the two new species described here are distinguished from other congeneric species by morphological, genetic, and biological characteristics.

Chinese time adverbs describe status of behavior, modal frequency, or that the behavior has occurred, occurred in the past, present or future. When describe a time, it usually emphasizes the meaning. Indonesian time adverbs describe an event or action occurred at a time. It indicates the status of behavior, modal or indicates whether the conduct has occurred, has not happened, will happen, repeat and describe the act or thing is not yet completed. This study attempts to shed light on why students incline to make mistake in using Chinese time adverbs. Furthermore, students face difficulty in differentiating between Chinese and Indonesian time adverbs. Chinese Indonesia have the similar meaning of time adverb, such as: gang, yijing, cengjing, zhengzai, jiang, hai, mashang but function in a sentence not exactly same.

The Panamic biogeographic province has long been thought to harbour a rich pyramidellid fauna. In the compilation of Keen (1971) the family is second only to the Turridae in being the most speciose gastropod family in the region, and no less than 350 species are listed. However a number of these have later been recognized to be synonyms, and in the update of the compilation by Skoglund (2002) the number of pyramidellids was reduced to 258.

Peniculus asinus, a new species of copepod parasitic on Sebastes (Pisces: Teleostei) off the Pacific coast of Canada is described and illustrated. The copepod is an unique member of its genus in that it possesses cephalothoracic holdfast processes. The discovery of a Peniculus with these processes is taken as evidence confirming the place of this genus in the family Pennellidae.

In the past two years an Afrocolombian hip-hop band from the Pacific region of Colombia has been getting a lot of attention in the media, especially after winning a Latin Grammy Award in 2010 and being nominated to several categories of the Grammy Music Awards in 2011 and 2012.  In their lyrics, they claim to represent the black population of the Pacific coast, people of African descent who have traditionally lived in marginalized conditions of poverty and exploitation of different sorts.  By borrowing some insights from African American criticism, the afrocentricity in Choquibtown's songs is explored.  Additionally, through a postcolonialist approach, this band's musical production is analyzed as a voice of widespread racism and as means of resistance to political and cultural oppression.

Review of Idyllic No More: Pacific Island Climate, Corruption and Development Dilemmas, by Giff Johnson. Majuro, Marshall Islands: CreateSpace. 2015. 153 pp. ISBN 978-1-512235-58-6Giff Johnson’s latest work, Idyllic No More: Pacific Islands Climate, Corruption and Development Dilemmas, is a call to serious planning and more. The Marshall Islands Journal editor summons leaders to recognise that life has changed in the country and the status quo is the road to disaster. There was a time when this might not have been true—when people who wanted to kick back and live a simple island life could quietly opt out of school and retire to the family land to provide for themselves as their ancestors had done for generations in an island society that offered the resources, physical and social, to support its population.

Liopropoma aragai Randall & Taylor 1988 is redescribed based on the holotype and non-type specimens from Japan and Taiwan. Diagnostic characters of the species and the status of Taiwanese specimens previously referred to L. aragai are reassessed. Liopropoma lemniscatum Randall & Taylor 1988, previously recorded only from the Pacific coast of Japan and the Ryukyu Archipelago, and L. lunulatum (Guichenot 1863), previously known from Okinawa Island (Japan), Guam, Réunion, Rarotonga and Tahiti, are redescribed, both being confirmed for the first time by voucher specimens from Taiwanese waters. A detailed description of each species and a key to Taiwan Liopropoma Gill 1861 is provided.
