An assessment of the potential to use water chemistry parameters to define ground water flow pathways at Grand Canyon National Park, Arizona

The purpose of this study is to assess the potential to use water chemistry parameters to determine ground water flow pathways at the south rim of Grand Canyon National Park, Arizona. South rim spring, ground, and surface waters and one north rim spring were sampled from September 1992 through September 1993. Field measurements (pH, electrical conductivity, alkalinity, temperature, total dissolved solids, and dissolved oxygen), major anion (fluoride, chloride, bromide, nitrate, phosphate, and sulfate) concentrations, selected trace element concentrations, and the ratios of the stable isotopes of oxygen and hydrogen. Major anion, trace element, and field measurement data were analyzed using the multivariate statistical technique Principal Component analysis as a quantitative means for differentiating between waters according to hydrochemistry. The analysis suggests that springs issuing from similar lithologic units and/or geographic localities have analogous chemistry; that local ground water hydrochemistry is similar to south rim springs water chemistry, and particularly those issuing from the Redwall-Muav Limestones.

Determining and addressing the needs of transracial Korean adoptees in higher education

One out of ten Korean Americans is estimated to be an adoptee (McGinnis, 2007). The majority of these adopted Korean Americans are transracial adoptees (TRAs), a group that has not received enough attention despite their unique experiences, perspectives, and needs. On top of the unique challenges TRAs face throughout life in general, most young adults go on to pursue a higher education which is a developmentally challenging time for anyone, pushing students to define their own values and personal identity (Long, 2012). According to the U.S. State Department Bureau of Consular Affairs (2018), there were 20,800 transracial Korean adoptees (TRKAs) adopted between 1999 and 2018. Hoffman and Peña’s (2013) study about TRKAs for application in higher education suggested that, based upon the previous statistic, there are probably a significant number of TRKAs currently in higher education and will be for the next several years. The purpose of this study was to advocate for these students, and identify the unique supports they may require in order to develop successfully as well rounded individuals

Observing Rapport-Based Interpersonal Techniques to Gather Information from Victims

The observing rapport-based interpersonal techniques (ORBIT) behavioral coding manual (Alison, Alison, Noone, Eltnib, & Christiansen, 2013) was used to code 103 hr of investigative interviews with sexual offense victims—a sample of 86 single-victim cases conducted by 26 police interviewers in South Korea. In all cases, there was a subsequent conviction. ORBIT is comprised of two key psychological approaches previously used most often in counseling but applied here to law enforcement. These are (a) humanistic approaches that are honest, empathic and nonjudgmental and (b) an interpersonal behavior circle of dyadic interaction between interviewer and victim based on power-submission and conflict-cooperation dimensions, which can be managed in a prosocial (adaptive) or antisocial (maladaptive) way by the interviewer. Information/evidence yield was coded as a dependent variable. Coding was conducted every 15 min, representing 316 coding units. Results showed that (a) humanistic approaches positively influence adaptive interactions between interviewer and victim while simultaneously reducing maladaptive ones, the consequence of which is an increase in yield; (b) interviewer adaptive behaviors directly increase victim adaptive behavior (with the same effect for maladaptive behavior); and (c) victim adaptive behavior is positively associated with interview yield, and victim maladaptive behavior is negatively associated with it. These results suggest that interviews conducted in a humanistic-consistent fashion strongly positively influence adaptive victim behavior, which, in turn, increases interview yield

INTRODUCTION TO THE SPECIAL ISSUE: PAPERS FROM THE CONFERENCE “RECENT ADVANCES IN THE ARCHAEOLOGY OF EAST AND SOUTHEAST ASIA”

This special issue of the Journal of Indo-Pacific Prehistory Association presents some of the results of a small conference entitled “Recent Advances in the Archaeology of East and Southeast Asia.” The event was held in Madison, Wisconsin, and brought together a collection of scholars from the US and abroad. Organized by Nam Kim and Alison Carter, the conference was hosted at the University of Wisconsin-Madison (March 15-16, 2013), and was jointly sponsored by the Department of Anthropology, the Center for East Asian Studies, and the Center for Southeast Asian Studies

Immigration Legislation and Issues in the 111th Congress

[Excerpt] The Speaker of the House and the Senate Majority Leader have pledged to take up comprehensive immigration reform legislation at some point in the 111th Congress. Efforts to enact broad immigration reform in the 109th and 110th Congresses were unsuccessful. It is unclear what the components of any immigration reform proposals that the 111th Congress may consider will be. In the past, comprehensive bills have addressed border security, enforcement of immigration laws within the United States (interior enforcement), employment eligibility verification, temporary worker programs, permanent admissions and, most controversially, unauthorized aliens in the United States. The 111th Congress has considered various immigration issues and has enacted a number of targeted immigration provisions. It has passed legislation (P.L. 111-8, P.L. 111-9, P.L. 111-68) to extend the life of several immigration programs—the E-Verify electronic employment eligibility verification system, the Immigrant Investor Regional Center Program, the Conrad State J-1 Waiver Program, and the special immigrant visa for religious workers—all of which are currently authorized until October 31, 2009. With respect to these programs, the House-passed and Senate-passed versions of the Department of Homeland Security Appropriations Act, 2010 (H.R. 2892), include different provisions to further extend E-Verify. The Senate-passed bill also would extend the other three programs. Among the other subjects of legislation enacted by this Congress are refugees (P.L. 111-8) and border security (P.L. 111-5, P.L. 111-32). This report discusses these and other immigration-related issues that have seen legislative action or are of significant congressional interest. Department of Homeland Security (DHS) appropriations are addressed in CRS Report R40642, Homeland Security Department: FY2010 Appropriations, and, for the most part, are not covered here. This report will be updated as legislative developments occur

Appropriate Methodologies to Better Measure Consumer Preferences for Postal Services

This report summarises work undertaken testing the use of stated preference discrete choice experiments to measure consumer preferences for postal services. It discusses the importance of understanding and quantifying consumer priorities in the postal sector and presents different methods used for valuing non-market goods. We recommend the use of stated preference discrete choice experiments, and test the use of this approach in three member states. We provide the findings for these member states, as well as a “tool kit” for applying this methodology in other member states in future.Consumer preferences, postal services, discrete choice, two-sided market

Energy saving measures for automotive air conditioning (AC) system in the tropics

Air conditioning (AC) is an integral component of modern cars in the tropics. However, AC usage in this region consumes a large amount of energy. In conventional internal combustion engine cars, it consumes up to 30% of the fuel, while in battery electric cars, AC may reduce the battery range by up to 40%. Fortunately, there are various ways to improve the efficiency of automotive ACs in the tropics. In this paper, three energy saving measures are discussed. These include a higher indoor temperature setting, a smaller temperature lift and a separate dehumidification system. The study suggests that increasing the indoor temperature setting alone from 20°C to 24°C can save about 22% of the compressor power and increase the COP by up to 13%. Reducing the temperature lift by reducing the temperature difference between the condensing and ambient temperatures can potentially save up to 30% of the compressor power and increase the COP by 45%. An important requirement of this method is the need for a compact and lightweight heat exchanger design. The separation of dehumidification and cooling is very effective as it reduces the thermal load and allows for a higher evaporating temperature. About 50% compressor power saving can be achieved with a dehumidification system. An important requirement is that the energy for regeneration of the dehumidifier must come from waste energy. Finally, combination of all the methods can save compressor power requirement of automotive AC systems in the tropics by up to 70%
