Editor\u27s Notes
This issue of the Review is respectfully dedicated to Professor Rudolph H. Nottelmann who has served the Review in various capacities for the past thirty-four years. The picture of Professor Nottelmann appearing in this issue is from a portrait hanging in Condon Hall which was dedicated in 1956 on the completion of Professor Nottelmann\u27s twenty-ninth year of teaching at the University of Washington. The Editorial Board and the staff of the Review join with Professor Richards (see page 103) in wishing Rudy the best in his post retirement endeavors
The Washington Law of Arrest Without Warrant—Incidental Search
The scope of this comment is limited to considerations of the substantive law of arrest without a warrant and the permissible scope of searches and seizures incidental thereto. The discussion of substantive requirements for arrest without warrant and its incidental search will be confined to present Washington case law as measured against the federal constitutional and common law backgrounds
Winning Isn’t Everything: Corruption in Sumo Wrestling
Although theory on corruption is well developed, it has proven difficult to isolate corrupt behavior empirically. In this paper, we provide overwhelming statistical evidence documenting match rigging in Japanese sumo wrestling. A non-linearity in the incentive structure of promotion leads to gains from trade between wrestlers on the margin for achieving a winning record and their opponents. We show that wrestlers win a disproportionate share of the matches when they are on the margin. Collusion, rather than increased effort, appears to explain the results. Wrestlers who are victorious when needing a victory lose more often than would be expected the next time they meet that same opponent, suggesting that part of the payment for throwing a match is future payment in kind. Cheating disappears in times of high media scrutiny. In addition to collusion by individual wrestlers, there is also evidence of reciprocity agreements across stables of wrestlers, suggesting a centralized element to the match rigging
Identifying invertebrate invasions using morphological and molecular analyses: North American Daphnia ‘pulex’ in New Zealand fresh waters
We used a DNA barcoding approach to identify specimens of the Daphnia pulex complex occurring in New Zealand lakes, documenting the establishment of non-indigenous North American Daphnia 'pulex'. Morphological delineation of species in this complex is problematic due to a lack of good morphological traits to distinguish the species, as there is a relatively high degree of morphological stasis within the group through evolutionary time. Accordingly, genetic analyses were used to determine the specific identity and likely geographic origin of this species. Morphologically, individuals most closely resembled Daphnia pulicaria or Daphnia pulex sensu lato, which cannot be separated morphologically. Furthermore, each of these taxa comprises separate species in North America and Europe, despite carrying the same names. We identified individuals using a 658 bp nucleotide portion of the mitochondrial cytochrome c oxidase subunit 1 gene (COI) as North American Daphnia 'pulex', being distinct from European Daphnia pulex sensu stricto and D. pulicaria from Europe or North America. Cellulose allozyme electrophoresis was used to confirm that individuals were not hybrids with D. pulicaria. North American Daphnia 'pulex' in New Zealand were first recorded in New Zealand from South Island lakes that are popular for overseas recreational fishers, indicating a possible source of introduction for this species (e.g. on/in fishing gear). Our study provides an additional example of how genetic techniques can be used for the accurate identification of non-indigenous taxa, particularly when morphological species determination is not possible. The growth of global databases such as GenBank and Barcode of Life Datasystems (BOLD) will further enhance this identification capacity

Winning Isn't Everything: Corruption in Sumo Wrestling
Although the theoretical literature on corruption is well developed, empirical work in this area has lagged because it has proven difficult to isolate corrupt behavior in the data. In this paper, we look for evidence of corruption in an unlikely place: the highest echelons of Japanese sumo wrestling. This paper provides strong statistical evidence documenting match rigging in sumo wrestling. A non-linearity in the incentive structure of promotion leads to gains from trade between wrestlers on the margin for achieving a winning record and their opponents. We show that wrestlers win a disproportionate share of the matches when they are on the margin. Increased effort can not explain the findings. Winning on the bubble is more frequent when the two competitors have met often in the past. Success on the bubble tends to rise over the course of a wrestler's career, but declines in his last year, consistent with the game theoretic predictions. Wrestlers who are victorious when on the bubble lose more frequently than would be expected the next time they meet that opponent, suggesting that part of the payment for throwing a match is future payment in kind. Systematic differences across wrestling stables suggest that the stables play a role in facilitating the corruption. In times of increased media scrutiny, the match rigging disappears.
Examining the use of drama to develop epistemological understanding about the nature of science: A collective case from experience in New Zealand and England, UK
Understanding the nature of science (NoS) is perplexing for young children because it is concerned with not only understanding how evidence is generated but also what kind of meanings can be made from information collected. However, acting as a scientist-in-role, making independent decisions about what information to collect and deciding how to go about it, can enable students to experience scientific practices that empower them to better appreciate and understand the NOS. This paper illustrates how drama processes, in two international settings in Wellington, New Zealand and Oxford, United Kingdom encouraged nine to ten year old children to engage in the scientific ‘as-if’ world. The data collected from these two locations was analysed deductively to illustrate how working-in-role can influence the nature of learning and shape the scientific practices experienced that consequently inform how the NoS is understood. The children in Wellington (New Zealand) worked in-role as atmospheric scientists to design a reduced-emissions race track. The class in Oxford (UK) adopted the role of technological scientists theorising about properties of materials to create and test original carriers designed to transport a range of everyday objects. How drama promoted working-in-role to experience scientific practices supporting the understanding of the NoS, are discussed. The findings suggest that being in-role as a scientist offered learners various opportunities to be agentive, to think and act scientifically, better appreciate the nature of work that scientists do and consequently appreciate the NoS
Triangulum II: Not Especially Dense After All
Among the Milky Way satellites discovered in the past three years, Triangulum
II has presented the most difficulty in revealing its dynamical status. Kirby
et al. (2015a) identified it as the most dark matter-dominated galaxy known,
with a mass-to-light ratio within the half-light radius of 3600 +3500 -2100
M_sun/L_sun. On the other hand, Martin et al. (2016) measured an outer velocity
dispersion that is 3.5 +/- 2.1 times larger than the central velocity
dispersion, suggesting that the system might not be in equilibrium. From new
multi-epoch Keck/DEIMOS measurements of 13 member stars in Triangulum II, we
constrain the velocity dispersion to be sigma_v < 3.4 km/s (90% C.L.). Our
previous measurement of sigma_v, based on six stars, was inflated by the
presence of a binary star with variable radial velocity. We find no evidence
that the velocity dispersion increases with radius. The stars display a wide
range of metallicities, indicating that Triangulum II retained supernova ejecta
and therefore possesses or once possessed a massive dark matter halo. However,
the detection of a metallicity dispersion hinges on the membership of the two
most metal-rich stars. The stellar mass is lower than galaxies of similar mean
stellar metallicity, which might indicate that Triangulum II is either a star
cluster or a tidally stripped dwarf galaxy. Detailed abundances of one star
show heavily depressed neutron-capture abundances, similar to stars in most
other ultra-faint dwarf galaxies but unlike stars in globular clusters.Comment: accepted to ApJ, Table 5 available as a machine-readable table by
