WHO CAN FISH WHAT AND WHERE: CHILE'S TRADEOFFS IN HIGH SEAS FISHING OF STRADDLING STOCKS

Chile has not yet ratified the U.N. 1995 Agreement on straddling/ highly migratory fish stocks. This paper discusses key economic issues at stake from the viewpoint of a coastal state with important stakes in a straddling stock. The Chilean jack mackerel stock, one of Chile's most important fish resources, is in this category. This stock is currently caught on adjacent high-seas only by a Chilean-flag fleet, and currently there is no evidence of imminent competition from distant water fishing nations (DWFNs). We argue that ratification of the Agreement could imply negative effects on: (i) coastal states' sovereignty upon management measures within its Exclusive Economic Zone (EEZ) and (ii) national fishing companies' competitiveness. Despite this, the net cost/benefit balance depends on how binding the threat of DWFNs' fishing competition is expected to be. If the Agreement does go into force, coastal states with important stakes in straddling fish stocks will feel increased pressure to ratify as well. For the case of states that become parties to the Agreement, we discuss pending obstacles for achieving effective fishery management in the adjacent high-seas. We speculate about possible solutions to the 'New Member' and 'Interloper' problems. Regarding the former, enforceable closed access would seem to be legally feasible under the Agreement. In terms of effective enforcement against fishing by illegal interlopers, innovation in enforcement tools would be needed. In some cases, the latter may require further adjustments to the Law of the Sea Convention.Resource /Energy Economics and Policy,

Policy and Practice Brief 6: Considerations for Using ACCESS Test Scores in Decision-Making

Since the implementation of The No Child Left Behind Act of 2001 (NCLB), all students identified as English learners (ELs) in U.S. public schools have been required to take an annual assessment of English language proficiency (ELP) for federal accountability. Virginia and many other state education agencies (SEAs) use the WIDA ACCESS for ELLs© test (ACCESS), not only to comply with this mandate, but also to inform a variety of high-stakes decisions for EL instruction, such as determining when multilingual learners have reached English proficiency, deciding about Language Instruction Educational Program (LIEP) entry and exit, informing classroom instruction and assessment, monitoring year-to-year student progress, deciding on staffing levels, and evaluating teachers. Despite the test’s long history, widespread adoption, multiple uses, and costs, few independent evaluations of the test have been conducted; however, study of Virginia EL teachers raised questions about the reliability of ACCESS and the validity of decisions based on the test scores. In light of these questions, considerations and recommendations for the administration of ACCESS and use of scores in high-stakes decision-making are presented

The Evolution of Interstate Security Crisis-ManagementTheory and Practice in China

As the frequency and scope of China’s paramilitary and military presence activities in the East and South China Seas have increased in the last few years, officials and analysts inside and outside China have worried more and more about the potential for military crises erupting between China and other actors. Given the perceived high stakes of many of these potential disputes—they touch on sovereignty, territorial integrity, national dignity, and development resources—some observers are concerned about the risks of escalation to military conflict, whether deliberate or accidental.1 Adding to the worries is uncertainty about China’s commitment to crisis management and escalation control.

Countdown to Consensus for Creating Marine Reserves in Antarctica's Southern Ocean

The seas surrounding the frozen continent of Antarctica harbor some of the most pristine marine ecosystems left on our planet, supporting an abundant yet fragile web of life. Whales, penguins, and seals share the waters of the Southern Ocean with thousands of spectacular but little-known creatures, such as bioluminescent worms, brilliant starfish, and ghostlike octopuses. Twenty-four countries and the European Union will soon decide whether to safeguard two vital areas of the Southern Ocean -- the Ross Sea and the East Antarctic -- from increasingly intensive fishing and other industrial activities

Exit Exams and High School Dropout

In this paper, I consider the impact of the expansion of exams students must pass in order to graduate high school on dropout rates. "Exit exams," as these tests are known, have become more common, and more difficult. These exams are controversial, with opponents claiming they drive marginal students out of school, and proponents arguing they align student interests with those of the school and encourage teachers and administrators to provide effort and resources on the students' behalf. I make use of the fact that when states implement exit exams, they first affect a specific graduating class. So in some states, some students in high school are required to pass these exams, while students in the grade above are not. Using a state-grade panel constructed from the Common Core of Data I find evidence that the recent expansion of exit exams has resulted in a modest increase in high school dropout rates in the aggregate, but a large increase among students in 12th grade, where additional attempts to pass exams are not possible. I also find that a policy often used to limit the impacts of exit exams on high school completion has only limited effect: Dropout rates in states where students can earn a diploma or credential even when unable to pass exit exams, dropout increases in 12th grade at about the same rate as in other states without such alternative pathways. This suggests that at least some of the impact is due to stop-out on the part of students.high school dropout, exit exams, accountability, attainment

An investigation of environmental factors associated with the current and proposed jetty systems at Belle Pass, Louisiana

The history of the existing jetty system at Belle Pass was investigated to determine its past effect on the littoral currents and beach erosion. Present flow patterns and erosion rates were also studied, along with the prevailing recession rates of local beaches not influenced by the jetty system. Aerial photographs and maps were used in conjunction with periodic hydraulic measurements, ground observations, and physical measurements of beach erosion. A scale model was constructed to further the study of flow patterns and velocities. It is shown that the existing jetty has not adversely affected the coastline in the area; erosive processes have been retarded by the jetty and its companion groin. Future erosion patterns are predicted, and projected effects of the proposed jetty system are given

Tidal influence on Rutford Ice Stream, West Antarctica: observations of surface flow and basal processes from closely-spaced GPS and passive seismic stations

High-resolution surface velocity measurements and passive seismic observations from Rutford Ice Stream, West Antarctica, 40 km upstream from the grounding line are presented. These measurements indicate a complex relationship between the ocean tides and currents, basal conditions and ice-stream flow. Both the mean basal seismicity and the velocity of the ice stream are modulated by the tides. Seismic activity increases twice during each semi-diurnal tidal cycle. The tidal analysis shows the largest velocity variation is at the fortnightly period, with smaller variations superimposed at diurnal and semi-diurnal frequencies. The general pattern of the observed velocity is two velocity peaks during each semi-diurnal tidal cycle, but sometimes three peaks are observed. This pattern of two or three peaks is more regular during spring tides, when the largest-amplitude velocity variations are observed, than during neap tides. This is the first time that velocity and level of seismicity are shown to correlate and respond to tidal forcing as far as 40 km upstream from the grounding line of a large ice stream

Dewey, Bruner, and Seas of Stories in the High Stakes Testing Debate

This paper proposes that many of the questions surrounding high stakes testing being debated today are important, yet fall short of moving teachers, parents, students, administrators and legislators to think deeply about how optimal teaching and learning can be achieved in a high stakes testing environment. Finally, the high stakes testing debate is viewed, to borrow a term from Bruner, as a sea of stories in which the stakeholders see the same things, but come away with remarkably differing stories of what is happening (1996, p. 147). The principles of learning espoused by Dewey and Bruner put these seas of stories into a different light by offering alternative ways of perceiving learning and teaching
