Salmon Fishery

The salmon fishery of the United States illustrates the major principles and problems of fishery management: regulation of the fishery, maintenance of the environment, and artificial augmentation of the stocks. It also includes controls both in fresh water and on the high seas. The industry has experienced the age-old conflicts between large- and small-scale fisheries, and administrators have had to wrestle with the problem of allocating the catch among various contenders. This problem has been confused with that of conservation. Prohibition of salmon traps, restrictions on size and mode of operation of purse seines, and prohibition of monofilament gillnets are examples of the kinds of compromises made between allocation and conservation.Dams, pollution, and other modifications of the freshwater environment have endangered salmon stocks. An early response was to raise salmon artificially and release them. For many years this technique was unsuccessful, and when it was evaluated most hatcheries were closed. In recent years the preservation of the genetic identity of the stock and improved diets and schedules of release have resulted in greater success of hatcheries. Spawning channels show promise of additional success. Another practice of value has been development of devices to pass fish over dams, both upstream and down.Control of fishing to provide adequate spawning has concentrated on manipulation of individual population units, an enormously complicated task since the number of these in United States streams is in the order of 10,000. Of these about 100 major ones are under separate control. Regulations depend on forecasts, since fishing takes place before the salmon reach spawning grounds. Forecasts have improved greatly in recent years, although much remains to be done.Among problems on which no great progress has been made are: extent and consequences of genetic change produced by selective fishing; causes of cycles, and alterations in these; effects of changing environment, especially subtle ones of temperature, dissolved oxygen, and pollution; control of recruitment, including release of hardy young. Difficult economic problems include: the tendency for regulations to favor inefficient operators; high costs of research and regulation, borne not by users but by public funds.Administrative achievements include: a high degree of environmental protection; remarkably parallel regulations in the three States principally involved, Alaska, Washington, and Oregon; successful joint regulation of international fisheries in cooperation with Canada and Japan.Problems which will continue to exist and increase in difficulty include protection of the environment of the salmon, rivalries between many diverse interest groups, and improvement in culture operations. The major step of restricting entry into the commercial salmon fishery is being contemplated in several locations.

Abstract Medical error is now recognized as one of the leading causes of death in the United States. Of the medical errors, diagnostic failure appears to be the dominant contributor, failing in a significant number of cases, and associated with a high degree of morbidity and mortality. One of the significant contributors to diagnostic failure is the cognitive performance of the provider, how they think and decide about the process of diagnosis. This thinking deficit in clinical reasoning, referred to as a mindware gap, deserves the attention of medical educators. A variety of specific approaches are outlined here that have the potential to close the gap.

The main problem posed in this study is: What are the content and structure of Jewish and American identity? The Jewish-American Identity Scale, which was adapted and refined for this study, was administered in 1971 to four samples, totaling 1006 Jewish-American college students from various parts of the United States. Initially, factor analysis was applied to the separate samples. Intersample comparisons of factor structures indicated a high degree of congruency; consequently, the samples were combined for subsequent analyses. Factor analysis of the test scores demonstrated that most of the common factor variance was appropriated by two relatively orthogonal factors. Items dealing with American identity and those dealing with Jewish identity had medium to high loadings on the two respective factors. These findings supported the hypothesis of the duality and the orthogonality of dimensions of Jewish and American identity, and cast doubt on the notion forwarded by some researchers that Jewish-American identity forms a bipolar continuum.

Abstract Background. The United States’ large-scale poultry meat industry is energy and water intensive, and opportunities may exist to improve sustainability during the broiler chilling process. After harvest, the internal temperature of the chicken is rapidly cooled to inhibit bacterial growth that would otherwise compromise the safety of the product. This step is accomplished most commonly by water immersion chilling in the United States, while air chilling methods dominate other global markets. A comprehensive understanding of the differences between these chilling methods is lacking. Therefore, we assessed the meat quality, shelf-life, microbial ecology, and technoeconomic impacts of chilling methods on chicken broilers in a university meat laboratory setting. Results. We discovered that air-chilling (AC) methods resulted in superior chicken odor and shelf-life, especially prior to 14 days of dark storage. Moreover, we demonstrated that AC resulted in a more diverse microbiome that we hypothesize may delay the dominance of the spoilage organism Pseudomonas. Finally, a technoeconomic analysis highlighted potential economic advantages to AC when compared to water-chilling (WC) in facility locations where water costs are a more significant factor than energy costs. Conclusions. In this pilot study, AC chilling methods resulted in a superior product compared to WC methods and may have economic advantages in regions of the U.S. where water is expensive. As a next step, a similar experiment should be done in an industrial setting to confirm these results generated in a small-scale university lab facility.

Assessing the output of past foreign policy is instrumental for any country to learn policy-relevant insights, to appreciate its experience, and to improve its future conduct. To glean such insights, this article borrows Baldwin’s framework in assessing the success and failure in foreign policy. Using a case study analysis, it assesses the United States’ (U.S.) influence attempt towards Indonesia to resolve the 1999 East Timor humanitarian crisis. President Clinton’s decision to undergo an influence attempt primarily aimed to change Indonesia’s policy while gaining support from U.S. allies in the process. The article finds that Clinton’s decision was a highly successful attempt. This finding is based on several factors: (1) the attempt effectively attained the intended primary and secondary goals at a considerably high degree; (2) it was conducted at a considerably low cost for the U.S.; (3) it inflicted a high cost towards Indonesia; (4) the increase in Clinton’s stake strengthened the U.S. resolve to pursue the influence attempt; and (5) Clinton had successfully overcome the difficult undertaking as Indonesia possessed higher stake over East Timor. These findings provide some lessons for both U.S. and Indonesian foreign policymakers to chart future relations for the two nations.

The United States has exceptionally strong Constitutional protections for free speech, but also for religious freedom. This chapter considers how this unique legal framework affects hate spin in the country. It finds that although hate speech can be expressed with a high degree of impunity, strong anti-discrimination laws limit the harms caused by such speech. Hate spin can, nonetheless, succeed in fostering fear and cultivating prejudice against minorities. The chapter examines how a network of anti-Muslim activists have used hate spin to campaign against mosque building, to oppose multi-cultural textbooks, and to introduce legislation protecting states from the fabricated threat of encroaching Muslim law. Beyond their stated goals, which may be frustrated by courts, these campaigns often have the symbolic purpose of spreading Islamophobia.

The last decade has witnessed the rapid growth of mobile communication devices and wireless technologies across the globe. The convergence of mobile devices and wireless technologies has not only changed the way many activities are conducted, but has also provided a foundation for a new type of technology-aided commerce called mobile commerce (m-commerce). As e-commerce’s next evolutionary stage, m-commerce opens up new business opportunities in business-to-consumer (B2C) markets in addition to extending current operations in e-commerce and traditional brick-and-mortar businesses (Varshney & Vetter, 2002). The significant power of m-commerce is primarily a result of the anytime-anywhere connectivity of wireless devices, which provides unique experiences and services (Figge, 2004; Zwass, 2003). One of the most promising and value-added m-commerce services is mobile banking (Lee, McGoldrick, Keeling, & Doherty, 2003; Mallat, Rossi, & Tuunainen, 2004). Mobile banking is the newest electronic delivery channel to be offered by banks in which technology has become an increasingly vital element, and it provides convenience and enhanced value to both banks and customers. With its clear benefits, mobile banking is now gaining rapid popularity in European and Asian countries with the significant market penetration of mobile handsets and the optimally designed marketing tactics of service providers (Suoranta & Mattila, 2004). However, mobile banking is still marginally adopted across the globe, and especially in the U.S., the growth appears much slower than anticipated (Mallat et al., 2004). In the United States, there are only a small number of banks that have actually introduced mobile banking services, and most other mobile banking efforts are in small-scale trials (Charny, 2001). Therefore, the technology which will be employed in the United States market has been of interest not only to financial institutions, but also to mobile technology developers and future users.

Abstract The parasitic mite Varroa destructor (Acari: Varroidae) is a major cause of overwintering honey bee (Apis mellifera) colony losses in the United States, suggesting that beekeepers must control Varroa populations to maintain viable colonies. Beekeepers have access to several chemical varroacides and nonchemical practices to control Varroa populations. However, no studies have examined large-scale patterns in Varroa control methods in the United States. Here we used responses from 4 yr of annual surveys of beekeepers representing all regions and operation sizes across the United States to investigate use of Varroa control methods and winter colony losses associated with use of different methods. We focused on seven varroacide products (amitraz, coumaphos, fluvalinate, hop oil, oxalic acid, formic acid, and thymol) and six nonchemical practices (drone brood removal, small-cell comb, screened bottom boards, powdered sugar, mite-resistant bees, and splitting colonies) suggested to aid in Varroa control. We found that nearly all large-scale beekeepers used at least one varroacide, whereas small-scale beekeepers were more likely to use only nonchemical practices or not use any Varroa control. Use of varroacides was consistently associated with the lowest winter losses, with amitraz being associated with lower losses than any other varroacide product. Among nonchemical practices, splitting colonies was associated with the lowest winter losses, although losses associated with sole use of nonchemical practices were high overall. Our results suggest potential control methods that are effective or preferred by beekeepers and should therefore inform experiments that directly test the efficacy of different control methods. This will allow beekeepers to incorporate Varroa control methods into management plans that improve the overwintering success of their colonies.

Post Cold War

In December 1979, Soviet troops entered the small, poor, landlocked, Islamic nation of Afghanistan, assassinated the communist president, Hafizullah Amin, and installed a more compliant Afghan leader. For almost ten years, Soviet troops remained entrenched in Afghanistan before finally withdrawing in February 1989. During this period, the United States undertook a covert program to assist the anti-communist Afghan insurgents—the mujahideen—to resist the Soviet occupation. Beginning with President Jimmy Carter’s small-scale authorization in July 1979, the secret war became the largest in history under President Ronald Reagan, running up to $700 million per year. The Central Intelligence Agency (CIA) acted as the war’s quartermaster, arranging supplies of weapons for the mujahideen, which were funneled through Pakistan’s Inter-Services Intelligence directorate (ISI), in coordination with Saudi Arabia, China, Egypt, and others. No Americans were directly involved in the fighting, and the overall cost to the American taxpayer was in the region of $2 billion. The Afghan cost was much higher. Over a million Afghans were killed, a further two million wounded, and over six million refugees fled to neighboring Pakistan and Iran. For the Soviet Union, the ten-year war constituted its largest military action in the postwar era, and the long and protracted nature of the conflict and the failure of the Red Army to subdue the Afghans is partially responsible for the internal turmoil that contributed to the eventual breakup of the Soviet empire at the end of the 1980s. The defeat of the Soviet 40th Army in Afghanistan proved to be the final major superpower battle of the Cold War, but it also marked the beginning of a new era. The devastation and radicalization of Afghan society resulted in the subsequent decades of continued conflict and warfare and the rise of militant Islamic fundamentalism that has shaped the post-Cold War world.

Novel Coronavirus

The novel coronavirus reached the United States and Canada almost at the same time. The first reported American case was January 20, 2020, and in Canada it was January 15, 2020 (Canada, 2020; Holshue et al., 2020). Yet, the response to this crisis has been different in the two countries. In the US, President Donald Trump, prominent Republicans, and conservative media initially dismissed the dangers of COVID-19 (Stecula, 2020). The pandemic became politicized from the early days, and even though Trump and Republicans have walked back many of their initial claims, there continue to be media reports of partisan differences in public opinion shaped by that early response. At the same time, the response in Canada has been mostly characterized by across-the-board partisan consensus among political elites (Merkley et al., 2020).
