Abstract: Marine environmental monitoring has tended to focus on site-specific methods of investigation. These traditional methods have low spatial and temporal resolution and are relatively labour intensive per unit area/time that they cover. To implement the Marine Strategy Framework Directive (MSFD), European Member States are required to improve marine monitoring and design monitoring networks. This can be achieved by developing and testing innovative and cost-effective monitoring systems, as well as indicators of environmental status. Here, we present several recently developed methodologies and technologies to improve marine biodiversity indicators and monitoring methods. The innovative tools are discussed concerning the technologies presently utilized as well as the advantages and disadvantages of their use in routine monitoring. In particular, the present analysis focuses on: (i) molecular approaches, including microarray, Real Time quantitative PCR (qPCR), and metagenetic (metabarcoding) tools; (ii) optical (remote) sensing and acoustic methods; and (iii) in situ monitoring instruments. We also discuss their applications in marine monitoring within the MSFD through the analysis of case studies in order to evaluate their potential utilization in future routine marine monitoring. We show that these recently-developed technologies can present clear advantages in accuracy, efficiency and cost.

Abstract: The academic department remains understudied as a context of faculty work, particularly in institutional settings beyond the research university. In this article, we report findings from a study of faculty experiences within academic departments in liberal arts colleges, through analysis of interviews with 55 faculty members representing a 13-member consortium of liberal arts institutions in the mid-western U.S. Through inductive analysis and deductive coding from existing models, we identified five functions of departments in liberal arts colleges, including: (a) faculty hiring, retention, and promotion; (b) new faculty socialization; (c) informal interactions, mentoring, and network-building; (d) establishing and communicating institutional and departmental policies, practices, and procedures; and (e) the structuring of academic work. Findings suggest that departmental functions in liberal arts colleges are generally the same as those in other institution types, but play out differently and thus have different consequences for academic careers. Across functions, liberal arts colleges seem to be undergoing an evolution, or perhaps revolution, that has implications for academic work in such contexts.

Abstract:

Fieldwork conducted in the Wasatch Formation in and around Fossil Butte has yielded a diverse assemblage of early Eocene vertebrates. Fossil vertebrates are distributed through three discrete stratigraphic intervals within the uppermost 180 m of the main body of the Wasatch Formation underlying the Green River Formation. These assemblages were derived primarily from fluvial overbank mudstone units overprinted with variably well-developed paleosols. The lowest (20 m) and highest (60 m) sections are characterized by less mature and more hydromorphic paleosols, whereas the middle section (100 m) is typified by more mature paleosols and more abundant channel sandstones.

The combined assemblages contain at least 46 species of mammals. Faunal characteristics include high abundances of equid perissodactyls and a relatively high abundance and diversity of notharctines primates, an apparent absence of omomyid primates, relatively high rodent diversity, and relatively diverse and abundant artiodactyls. One new genus (Eoictops new genus) and three new species (Eoictops novaceki new species, Palaeosinopa lacus new species, and ?Notoparamys blochi new species) are included in the Fossil Butte assemblage. Also recorded are late occurrences of two hyopsodontid condylarths and an early occurrence of a rare phenacodontid condylarth. The relatively high abundances of equids and notharctines suggest that vertebrate samples were derived from relatively open paleohabitats that included forested areas along water courses.

All three assemblages contain characteristic Lysitean (Wasatchian biochron Wa-6) elements, but the occurrence of the palaeotheriid perissodactyl Lambdotherium in the uppermost horizon indicates a Lostcabinian (Wa-7) age for at least the top of the Wasatch Formation. The overlying predominantly fish-bearing Fossil Butte Member of the Green River Formation also contains Lambdotherium and is therefore Wa-7 in age as well.

Abstract: Surfaces of cultural monuments are covered with diverse surface-associated microbial assemblages as a result of the substrata such as limestone that the monuments are constructed with as well as the impacts of various environmental pressures on these perpetually exposed structures over a long period. The aim of this study was to examine and compare the epilithic microbial assemblages on two Maya (i.e. Altun Ha and Xunanthunich) sites located in Belize.

High-throughput 454 pyrosequencing approach was utilized to elucidate microbial community assemblages on two monuments. Overall, the taxonomic composition of the epilithic assemblages on both sites revealed the numerical dominance by members of the Proteobacteria at 43% and 36.9%, and the Cyanobacteria at 25.8% and 16.6% on Altun Ha and Xunanthunich, respectively. Comparatively, sequence diversity appeared more pronounced among the epilithic assemblages found on Xunanthunich than those on Altun Ha.

Abstract: In this article we report on a study that represents the first step in a multi-year, multi-institutional research project, “Faculty Across Career Stages: Building Capacity for Undergraduate Research, Scholarship, and Creative  Work,” which aims to develop a more comprehensive portrait of faculty mentors of undergraduate researchers. We analyze archival data from two liberal arts colleges and one public research institution. The dataset  included demographic information on 198 faculty members who supervised undergraduate researchers in formal experiences between 2009 and 2014. The undergraduate research (UR) included supervised summer and academic-year experiences, but it was defined differently by different institutions, depending on their records. Discipline and faculty rank were important characteristics associated with faculty mentoring of undergraduate researchers, but gender was not. The study highlights a need for mixed-method research to understand better departmental and institutional influences on faculty members’ engagement in UR. We believe directors of undergraduate research programs should document faculty mentors’ participation according to at least three standard categories—faculty rank, discipline, and gender.

Abstract:  Previous study of subducted continental crust within the Luliang Shan terrane in Northwest China has documented metasomatic formation of thick, hydrated phengite + garnet-rich selvages at the interface between mafic eclogite blocks and quartzofeldspathic host gneiss. Whole rock concentrations of Cs and Ba within the selvage are enriched by two orders of magnitude relative to the eclogite blocks and host gneiss. We performed in situ ion microprobe analyses of Li, Be, B, Rb, Sr, Cs and Ba and δ11B of phengite within the Luliang Shane terrane to better constrain the source(s) of the infiltrating fluid. The phengite within the selvage are enriched in Li, Cs and Ba and yield δ11B values between −30‰ and −9‰, values that are lower than mantle values. High Ba/Rb, Cs/Rb coupled with low B/Be, B/Li and highly negative δ11B values indicate that the high-pressure fluid that formed the selvage was derived from highly devolatilized rocks within the subduction channel. In contrast, muscovite, which crystallized in the adjacent host gneiss during a subsequent lower pressure phase of fluid infiltration at approximately 0.9 GPa depths, has much lower Li, Cs and Ba relative to the high-pressure phengite. These retrograde muscovite have very high concentrations of B (up to 5500 ppm) and Be (up to 50 ppm) and high (−2 to +8‰) δ11B values that are consistent with crystallization from a fluid derived from shallower and less devolatilized regions of the subduction zone. Additional host gneiss samples, regionally distributed and kilometres away from the studied area lack the B-rich signature and indicate that the late stage fluids were likely localized to the region near the studied traverse.

Abstract: It is important to assess periodically how introductory textbooks portray our discipline because introductory psychology is the most popular psychology course, almost all teachers use textbooks for it, and textbooks play a major role in defining the course for students. To do so, past studies have used textbook citation analyses. We analyzed current textbooks to update the citation findings of these studies for the most cited articles, books, and psychologists. Many highly cited articles and books have decreased in citation frequency, likely due to a currency bias and authors’ citation preferences. Freud had the highest citation page count, reinforcing students’ misconception of his importance in contemporary scientific psychology. Our findings should help teachers in making choices about course content and emphases.

Abstract: This article focuses on the challenges faced by faculty members in a consortium of 13 Liberal Arts Colleges (LACs). We present findings, by academic rank, from a mixed-methods study of faculty development needs and experiences within the consortium. Relying on human resource principles, we advocate a greater focus on the development of the person, rather than task-specific skill improvement, as a means of creating faculty development programming that is particularly tailored to the rank-based needs of faculty members. We offer recommendations to achieve this focus amidst the unique faculty development challenges and opportunities available at LACs.

Abstract: This study investigated students’ attitudes, engagement, satisfaction, and performance in Introduction to Environmental Science after it was transformed from a typical large lecture to a student-centered learning environment. The instructors of the course collaborated with the Office of Teaching, Learning & Technology and radically redesigned the course by adopting evidence-based pedagogical methods and instructional technology to offer a rich active learning environment. Students’ engagement, satisfaction, and performance in the transformed course were compared to the students in the same course that was traditionally taught in a previous semester in order to measure the effect of the transformed course on student learning. Four self-reported surveys and a focus group interview were administered during the semester, and performance scores, prior learning data, and demographic information were collected at the end of the semester. The assessment results indicate that the students in the transformed course prepared for the class significantly more, engaged in the course significantly better, and were significantly more satisfied with the course than were the students in the traditional lecture-format course. Most of all, multiple linear regression indicates that the students in the transformed course earned, on average, about three-fourths of a letter grade higher on their final grade after controlling for cumulative grade point average. The students in the transformed course reported that online learning materials and frequent formative assessments using online quizzes were helpful in their learning, and they perceived the course was relevant to real-world applications that matter to their daily life.

Schoene, M. (2016). Urban Continent, Urban Activism? European Cities and Social Movement Activism. Global Society, 1-22.

Abstract: The European Union is currently experiencing a major protest wave. Citizens all over the continent are taking to the streets in droves to express their dissatisfaction with austerity policies, high unemployment, ineffective leadership and other issues. Many of these protests have been centred in large cities, but while some scholarly work notes the expressly urban nature of contemporary social movement activity, no studies test the effect of urban residential status on the likelihood of social movement participation in the presence of other factors. I hypothesise that cities positively influence the prevalence of social movement activity in the countries of the European Union. Using the multilevel 5th wave of the European Social Survey, I examine how urbanity, resources and grievances influence the likelihood of participation in four different forms of activism: wearing a protest badge, boycotting a product, signing a petition and participating in a demonstration. A series of multilevel mixed-effects regression models indicate that resources and urban status best predict the likelihood of participation in the four activities, indicating that cities offer better environments for social movement activity. I conclude with a discussion about European movement activity and urban society.

Publishers Description: Traditional choirs, folk ensembles or any other group of singers will enjoy this collection of songs from the Republic of Georgia selected, notated and recorded by Clayton Parr and Carl Linich. Like folk songs from the rest of the world, Georgian songs are traditionally connected with events of daily life – work songs, laments, lullabies, songs about historical events or figures, ritual songs, healing songs, traveling songs, comic songs, and dance songs. Table songs are a particularly important genre, and the tradition of the supra (ritual banquet), with elaborate toasts and songs, occupies a central position in Georgian traditional culture. Traditionally, these songs are in three polyphonic voice parts, and the authors have provided many pedagogical tools for learning: recordings, pronunciation guides, lyric sheets, song backgrounds and recordings.

Abstract: This paper describes a cross-sectional study of the combined influence of sleep and screen time behaviors on the odds of overweight and obesity among low-income youth. One of those most notable strengths of this study is the significant proportion of our sample who identify as members of an ethnic minority, most notably Hispanic and African American (approximately 84% of the total sample). This improves upon previous studies that often report data on almost entirely white samples, who often also do not qualify as low-income. Thus, we feel that this study makes a substantial contribution to the literature in spite of the null findings.

Abstract: We conducted a content-analysis of the websites of 100 institutional members of the Council of Undergraduate Research in order to examine the relationship between messages communicated on websites as compared to messages expressed within institutional procedures and policies. Findings show that public research institutions were more likely than baccalaureate institutions to have an Office of Undergraduate Research. Further incentives and supports provided by such offices are predominantly directed to students. Lastly, our analysis of promotion and tenure policies reveals that only 14 institutions out of the 100 in our sample explicitly mentioned mentoring undergraduate researchers in the evaluation criteria for faculty members. We offer implications for research and practice.

“What is it about the city of New Orleans? History, location, and culture, continue to link it to France while distancing it culturally and symbolically from the United States. This book explores the traces of French language, history, and artistic expression that have been present there over the last three hundred years. This volume focuses on the French, Spanish, and American colonial periods to understand the imprint that French socio-cultural dynamic left on the Crescent City. The migration of Acadians to New Orleans at the time the city became a Spanish dominion and the arrival of Haitian refugees when the city became an American territory oddly reinforced its Francophone identity. However, in the process of establishing itself as an urban space in the antebellum South, the culture of New Orleans became a liability for New Orleans elite after the Louisiana Purchase. New Orleans and the Caribbean share numerous historical, cultural, and linguistic connections. The book analyzes these connections and the shared process of creolization occurring in New Orleans and throughout the Caribbean Basin. It suggests ‘French’ New Orleans might be understood as a trope for unscripted ‘original’ Creole social and cultural elements. Since being Creole came to connote African descent, the study suggests that an association with France in the minds of whites allowed for a less racially-bound and contested social order within the United States.” (Provided by publisher)

Argon, oxygen, and boron isotopic evidence documenting 40ArE accumulation in phengite during water-rich high-pressure subduction metasomatism of continental crust. Earth and Planetary Science Letters, 446, 56-67.

Abstract: The Luliang Shan area of the North Qaidam high pressure (HP) to ultrahigh pressure (UHP) metamorphic terrane in northwestern China features thick, garnet- and phengite-rich metasomatic selvages that formed around gneiss-hosted mafic eclogite blocks during HP conditions. Here we present new 40Ar/39Ar, δ18O, and δ11B results from a previously studied 30 m, 18 sample traverse that extends from the host gneiss into a representative eclogite block. Previous thermobarometry and new mica-quartz oxygen isotope thermometry from the traverse reveal that the phengite-rich selvage formed at temperatures similar to those recorded by the eclogites at peak pressure. Quartz and white mica δ18O data from the selvage cannot be explained by simple mixing of gneiss and eclogite, and indicate a fluid/rock ratio >1 during regional-scale infiltration of high δ18O (ca. 14‰) fluids. Heavy δ18O overgrowths of metamorphic zircon over lighter δ18O detrital grains indicate that the gneiss was similarly affected. Starkly contrasting boron content and δ11B compositions for the host gneiss and the selvage also cannot be explained by local-scale devolatilization of the gneiss to form the selvage. Instead, the boron systematics are best attributed to two distinct phases of fluid infiltration: (1) low-boron selvage phengite with δ11B from −10 to −30‰ grew under HP conditions; and (2) tourmaline and boron-rich muscovite with generally positive δ11B crystallized in the host gneiss under subsequent lower pressure epidote–amphibolite facies conditions as the Luliang Shan gneiss terrane was exhumed past shallower portions of the subduction channel. Consistent with observations made worldwide, we were able to identify uptake of excess argon (40ArE) in phengite as a high pressure phenomenon. Phengite 40Ar/39Ar ages from massive eclogite exceed the ca. 490 Ma zircon U–Pb age of eclogite metamorphism by a factor of 1.5. However, phengite ages from the more permeable schistose selvage were even older, exceeding the time of eclogite formation by a factor of 1.7. In contrast, lower pressure retrograde muscovite present within the host gneiss and in discrete shear zones cutting the selvage yield 40Ar/39Ar ages that were younger than the time of HP metamorphism and consistent with regional cooling age patterns. Our observation of high 40ArE concentrations in phengite from schistose rocks infiltrated by regionally extensive fluids at HP conditions runs contrary to widely held expectations. Conventional wisdom dictates that low phengite/fluid partition coefficients for argon (View the MathML sourceView the MathML source) coupled with the dry, closed systems conditions that are widely reported to characterize HP metamorphism of continental crust explains why high concentrations of 40ArE partitions are able to accumulate within phengite. We alternatively propose that phengite/fluid partition coefficients for argon increase linearly with pressure to values as high as 10−2 to allow phengites to accumulate large amounts of 40ArE from aqueous fluids under HP to UHP conditions

Abstract: Borings in fossil turtle shells collected from the lowermost beds of the early Eocene Cathedral Bluffs Tongue of the Wasatch Formation in the northwestern part of the Green River Basin near South Pass, Wyoming, are herein described. Individual turtle shells in the study area are characterized by as few as one or two and as many as >100 borings. The borings include both non-penetrative forms (those which do not pass fully though the shell) as well as penetrative forms (those which pass fully from the exterior to the interior surface of the shell). All non-penetrative forms occur on external surfaces of the carapace and plastron (i.e. those that would have been accessible while the host taxon was alive). Two new ichnogenera and four new ichnospecies are established to describe these borings. Karethraichnus (new ichnogenus) includes three ichnospecies: K. lakkos (new ichnospecies), K. kulindros (new ichnospecies), and K. fiale (new ichnospecies). Karethraichnus lakkos are shallow (non-penetrating), hemispherical pits with rounded, to flattened bases. Karethraichnus kulindros are deep, non-penetrative traces with a cylindrical profile, an axis approximately perpendicular to the substrate surface and with rounded to flattened, hemispherical termini. Karethraichnus fiale are penetrative traces with a cylindrical to bi-convex or flask-shaped profile, and an axis approximately perpendicular to the substrate surface. Thatchtelithichnus (new ichnogenus) Thatchtelithichnus holmani (new ichnospecies) consist of non-penetrative borings into a bone substrate. They consist of a ring-shaped trace, with a central pedestal or platform. The position of the borings on the shells, and evidence of syn-emplacement healing of the borings in several of the turtles, indicates that these borings were emplacement by ectoparasites/mesoparasites while the animals were living. Similar traces in modern emydid turtles are attributed to ticks, leeches, or spirorchid liver flukes.

Abstract: In the course of a taxonomic revision of several clades of Greater Antillean Melastomataceae, we discovered a previously undescribed species, Miconia abscondita, from the Massif de la Hotte, Haiti. Miconia abscondita is based on a vegetative collection by Swedish botanist, E. L. Ekman, which was made in 1926. This new species is a member of the Mecranium clade, a group well supported on the basis of both morphological and molecular data, but which is highly embedded within the phylogenetic structure of the genus Miconia. Miconia abscondita is clearly placed within the Mecranium clade on the basis of DNA sequence data, and this placement also is supported by the form of its hairs and, especially, the pattern of stem indumentum; however, it matches no currently described species. Miconia abscondita is thus described, illustrated, and compared with putatively related and/or phenetically similar species. The discovery of M. abscondita brings to 25 the number of recognized species within the Mecranium clade and to 11 the number of species occurring in the Massif de la Hotte, Haiti, a region of exceptional biodiversity that is under continuous threat from anthropogenic pressure.

Abstract: The Harappan site of Desalpur is located in the western part of Kachchh District, Gujarat, India. This site was dicovered in the 1950s and was excavated in 1963‐64 (IAR 1963‐64), the brief report of which gives us the great potentiality of this site as this site was reported to have massive peripheral walls along with cultural deposits more than 2 m in thickness. The discovery of steatite and copper seals also adds importance to this site. However, the details of the excavations have not been published making it difficult to properly evaluate the significance of this site.

The Kachchh region has been known for the distribution of many Indus sites such as Dholavira, Juni Kuran, Kanmer, Shikarpur, Surkotada, Khirsara and so on. This region, surrounded by the Rann, which is presumed to have been filled with seawater during the third millennium BC, is highly likely to have flourished with sea trade as well as with land route trade connecting with Sindh, Balochistan and Gujarat. Therefore the investigations of archaeological sites of this region (Fig. 1) can contribute for better understanding of the urban society of the Indus Civilization that was sustained by rigorous inter‐regional interactions and trading networks. In this sense, the site of Desalpur has an imporatnce not only for establishing the local chronology but also for understanding the inter‐regional interactions between the Arabian Penninsula, Sindh and Gujarat.

This paper examines the ceramic evidence collected from Desalpur by Department of Archaeology, the University of Kerala in order to assess the archaeological importance of this site.

Abstract:

Objectives. Angiogenesis plays a critical role in SSc (scleroderma). The aim of this study was to examine the expression of growth-regulated protein-γ (Gro-γ/CXCL3), granulocyte chemotactic protein 2 (GCP-2/CXCL6) and their receptor CXCR2 in endothelial cells (ECs) isolated from SSc skin and determine whether these cells mount an angiogenic response towards pro-angiogenic chemokines. The downstream signalling pathways as well as the pro-angiogenic transcription factor inhibitor of DNA-binding protein 1 (Id-1) were also examined.

Methods. Skin biopsies were obtained from patients with dcSSc. ECs were isolated via magnetic positive selection. Angiogenesis was measured by EC chemotaxis assay.

Results. Gro-γ/CXCL3 and GCP-2/CXCL6 were minimally expressed in both skin types but elevated in SSc serum. Pro-angiogenic chemokine mRNA was greater in SSc ECs than in normal ECs. SSc ECs did not migrate to vascular endothelial growth factor (VEGF), Gro-γ/CXCL3, GCP-2/CXCL6 or CXCL16. The signalling pathways stimulated by these chemokines were also dysregulated. Id-1 mRNA in SSc ECs was lower compared with normal ECs, and overexpression of Id-1 in SSc ECs increased their ability to migrate towards VEGF and CXCL16.

Conclusion. Our results show that SSc ECs are unable to respond to pro-angiogenic chemokines despite their increased expression in serum and ECs. This might be due to the differences in the signalling pathways activated by these chemokines in normal vs SSc ECs. In addition, the lower expression of Id-1 also decreases the angiogenic response. The inability of pro-angiogenic chemokines to promote EC migration provides an additional mechanism for the impaired angiogenesis that characterizes SSc.

Abstract: Studies of doctoral education have included an interest not only in processes, structures, and outcomes, but also in students’ experiences. There are often useful recommendations for practice within individual examinations of the doctoral experience, yet there remains a need to strengthen the application of lessons from research to the behaviors of students and others engaged in the doctoral process. This paper is the first to synthesize research about doctoral education with the particular aim of informing practical strategies for multiple stakeholders. In this article, we summarize findings from a literature review of the scholarship about doctoral education from the past 15 years in a stage-based overview of the challenges of doctoral education. Our aim is to apply theory to practice through the systematic consideration of how research about doctoral education can best inform students and those who support them in the doctoral journey. We first present an overview of the major stages of doctoral education and related challenges identified in the research. We then consider key findings of that research to offer recommendations for doctoral students, faculty members, and administrators within and across stages.

Wilson, D. P. (2016). Protruding Features of Viral Capsids Are Clustered on Icosahedral Great Circles. PLoS ONE, 11(4), e0152319.

Abstract: Spherical viruses are remarkably well characterized by the Triangulation (T) number developed by Casper and Klug. The T-number specifies how many viral capsid proteins are required to cover the virus, as well as how they are further subdivided into pentamer and hexamer subunits. The T-number however does not constrain the orientations of these proteins within the subunits or dictate where the proteins should place their protruding features. These protrusions often take the form of loops, spires and helices, and are significant because they aid in stability of the capsid as well as recognition by the host organism. Until now there has be no overall understanding of the placement of protrusions for spherical viruses, other than they have icosahedral symmetry. We constructed a set of gauge points based upon the work affine extensions of Keef and Twarock, which have fixed relative angular locations with which to measure the locations of these features. This work adds a new element to our understanding of the geometric arrangement of spherical viral capsid proteins; chiefly that the locations of protruding features are not found stochastically distributed in an icosahedral manner across the viral surface, but instead these features are found only in specific locations along the 15 icosahedral great circles. We have found that this result holds true as the T number and viral capsids size increases, suggesting an underlying geometric constraint on their locations. This is in spite of the fact that the constraints on the pentamers and hexamer orientations change as a function of T-number, as you need to accommodate more hexamers in the same solid angle between pentamers. The existence of this angular constraint of viral capsids suggests that there is a fitness or energetic benefit to the virus placing its protrusions in this manner. This discovery may have profound impacts on identifying and eliminating viral pathogens, understanding evolutionary constraints as well as bioengineering for capsid drug delivery systems. This result also suggests that in addition to biochemical attachment restrictions, there are additional geometric constraints that should be adhered to when modifying protein capsids.

DeBruhl, H., Albertson, R., Swider, Z., & Sullivan, W. (2016). Rop, the Sec1/Munc18 homolog in Drosophila, is required for furrow ingression and stable cell shape during cytokinesis. Journal of Cell Science, 129(2), 430-443.

Abstract: Physically separating daughter cells during cytokinesis requires contraction of an actin-myosin ring and vesicle-mediated membrane addition at the cleavage furrow. To identify vesicle trafficking proteins that function in cytokinesis, we screened deficiencies and mutations of candidate genes by live imaging the mitotic domains of the Drosophila embryo. In embryos homozygous for some of these deficiencies, we observed several cytokinesis phenotypes, including slow furrow ingression and increased membrane blebbing. We also found that cytokinesis required the Sec1/Munc18 homolog Rop, which interacts with syntaxin and mediates exocytosis at the plasma membrane. In a temperature-sensitive Rop mutant (Rop(TS)), the contractile ring disassembled during furrow ingression, indicating that maintenance of the ring required vesicle addition. Furthermore, in some dividing Rop(TS) cells, the shape of the daughter cells became unstable, causing cytokinesis failure. These results further highlight the importance of vesicle trafficking in animal cytokinesis and show that vesicle fusion influences cell shape during cytokinesis.

Yoshii, M. (2014). The U.S. Stance Toward the 1962 Sino-Japanese Trade Agreement. Crossroads: Studies on the History of Exchange Relations in the East Asian World, 10, 197-212.

Abstract: On November 9, 1962, Japan concluded a five-year trade agreement with China, promising an exchange of $50 million worth of goods during 1963. U.S. Secretary of State, Dean Rusk, sent a message to Tōkyō criticizing Japan’s approach to Beijing especially as the timing of this deal coincided with the Sino-Indian border war. This paper examines the Kennedy administration’s policy toward Japan’s approach to Beijing. Rusk’s preoccupation with the Cold War and lack of a grasp of East Asian conditions led him to believe that the agreement was Japan’s first step toward recognizing Beijing. In contrast, the department’s East Asian specialists, particularly Ambassador Edwin O. Reischauer, had a better comprehension of the Sino-Japanese relations in the early 1960s based on their historical, cultural, and economic considerations. This paper provides not only the complex layers of the U.S. policy makers’ intentions, but also a fresh new look at the historical relations between Beijing and Tōkyō a decade before China’s mending of relations with the U.S. and Japan.
