Intercultural Communication Jul 2025

Intercultural Communication

Communication Research Trends

For the survival and development of important human values, the study of intercultural communication may be one of the critical areas of communication research. One has only to witness "Kojak" and "Starsky and Hutch" bouncing off satellites into the intimacy of minds and homes in cultures of India and Thailand to realize this. Vendors of communication technology are rushing to pen a Pandora's box of influences which may erode cultural ideals created over thousands of years. Once again we are not prepared to cope with the human and social implications of communication technology.

But the focus of research in intercultural …


Crucial Components Of An English Literacy Curriculum For Moroccan Adults, Philip J. Byler Mr. Jul 2025

Crucial Components Of An English Literacy Curriculum For Moroccan Adults, Philip J. Byler Mr.

Capstone Collection

This research paper examines the lived experiences and expertise of Moroccan teachers of English in teaching English literacy to Moroccan adults. Current research indicates that approximately 33 percent of Moroccan adults are illiterate. While there is research highlighting the need for adult literacy and its benefits, there is a lack of studies on how to develop an effective English literacy curriculum for Moroccan adults. Additionally, existing research underscores the growing importance of English in Morocco and the increasing desire among Moroccans to learn English.

Using a qualitative approach, this study explores the crucial components of an English literacy curriculum based …

Qualitative Tools To Enhance Data Analysis From Diverse Sources Of International Education Policy In Order To Create A More Perfect Evaluation Toolset, Robert J. Schulenburg

Capstone Collection

Abstract

This project proposes a new protocol for implementing meta-synthesis as a research tool. Meta-synthesis allows researchers to combine data sets from multiple sources that appear unconnected; it allows data sets to be extracted from multiple domains and knowledge banks that present as being unable to be combined or cross-transferable. This project presents a protocol designed to guide meta-synthesis which was used to extract critical relevant data from the Sustainable Development Goals (SDGs) related to inclusive education and inclusive work and rehabilitation policies and practices. The project shows with deliverables how, with this data in hand, newly aggregated extracted data …

Combat Motivation And Swift Trust In Canada’S Battle Of Hong Kong, 1941, Robert C. Engen, Maxwell Putnam Jul 2025

Combat Motivation And Swift Trust In Canada’S Battle Of Hong Kong, 1941, Robert C. Engen, Maxwell Putnam

Canadian Military History

Abstract: In December 1941, the British Crown Colony of Hong Kong was the site of a doomed last stand, when the Imperial Japanese Army assaulted the British enclave near-simultaneously with the strike on Pearl Harbor. Among Hong Kong’s multinational defenders were two battalions of Canadian infantry, designated “C Force.” They held out for a significant period and inflicted heavy casualties upon the Japanese, despite the fact that the Canadians were under-trained, under-equipped and fighting a battle that could not be won. This article is the first major study of combat motivation in the Battle of Hong Kong, taking the Canadian …


“Border Line Pilots”: Rcaf Aircrew, Crash Investigations And No. 22 Otu, Wes Cross Jul 2025

“Border Line Pilots”: Rcaf Aircrew, Crash Investigations And No. 22 Otu, Wes Cross

Canadian Military History

Abstract : In 1941, RAF Bomber Command Operational Training Units (OTU) in the United Kingdom were created to produce crews for the bomber offensive from graduates of the British Commonwealth Air Training Plan. Of the 4,000 RCAF deaths attributed to non-operational accidents, 1,498 occurred in this OTU phase. A study of No. 22 OTU accident reports, where the largest number of RCAF training fatalities occurred, provides insight into the stated official causes and underlying issues of the high accident rate. Of more recent interest is how one No. 22 OTU 1944 aircraft crash site decades later became a center of …


"That Movie Changed Me!" Effect Of Induced Mood On Story Interpretation, Rachel Deborah Thayer Jul 2025

"That Movie Changed Me!" Effect Of Induced Mood On Story Interpretation, Rachel Deborah Thayer

2025 Symposium

Studies have found that mood can affect a variety of aspects of cognition, such as memory, comprehension, and decision making. In one such study, participants identified with the character that reflected their hypnotically induced mood, and in another, story endings that were incongruent with the film clip-induced mood were more difficult to process. In the current study, film clips were used to induce moods, and participants were asked to write an ending to an ambiguous story. The prediction is that participants’ completions will reflect their induced mood. To date, 25 Eastern Washington University undergraduate students have been recruited and screened …

Examining Weight Bias Attitude Changes After Exposure To A Brief Photovoice Assignment, Gretchen L. George, Hillary L. Roberts, Kristin Rose, Madison Clemens, Kate G. Burt Jul 2025

Examining Weight Bias Attitude Changes After Exposure To A Brief Photovoice Assignment, Gretchen L. George, Hillary L. Roberts, Kristin Rose, Madison Clemens, Kate G. Burt

Journal of Dietetic Education

Weight bias is present among pre-health professional students (e.g., nutrition, dietetics, nursing, physical therapy, medicine). Educators need support and guidelines about how to enhance learning through engaging assignments while also meeting accreditation requirements. This pilot study examined the impact of an innovative weight bias assignment using photovoice and reflection within existing nutrition education courses, measured through pre-post assessments from the Fat Attitudes Assessment Toolkit. While not all subscales showed significant change, improvements in the Fat Acceptance and Attribution Complexity Composites suggest these methods may be effective in shifting attitudes about fatness. Further research is needed to assess the long-term impact …

Development Of Dietetics Students’ Skills And Self-Efficacy In The Nutrition Care Process, Kristen Heitman, Marcia Nahikian-Nelms, Holly Estes-Doetsch, Kristen M. Roberts, Jennifer A. Garner, Julie Kennel, Christopher A. Taylor

Journal of Dietetic Education

The Nutrition Care Process (NCP) is a systematic framework for providing nutrition care and a cornerstone of dietetics practice. Dietetics education relies on development of skills to achieve competence and demonstrate readiness for practice. The relationship between development of fundamental skills and self-efficacy among dietetics students preparing for clinical practice remains unclear. The purpose of this study was to examine the development of dietetics students’ skills in NCP documentation and their self-efficacy in performing the skills over one academic year. Student nutrition notes (n = 120 notes, n = 30 students) from standardized patient encounters were evaluated for quality using …

Use Of An Honest Signal By Red-Footed Boobies Sula Sula In Response To Kleptoparasitism By Great Frigatebirds Fregata Minor, Lin Chao Jul 2025

Use Of An Honest Signal By Red-Footed Boobies Sula Sula In Response To Kleptoparasitism By Great Frigatebirds Fregata Minor, Lin Chao

Marine Ornithology

On Genovesa Island (00.3°N, 089.9°W) in the Galápagos Islands, Ecuador, Great Frigatebirds Fregata minor kleptoparasitize (i.e., steal food from) Red-footed Boobies Sula sula. In five of eight cases that I observed, the frigatebirds harassed the boobies until the latter regurgitated their forage, which the frigatebirds consumed. In three cases, the booby responded with a honk-like call and the frigatebirds stopped harassing. I propose that the honk is an “honest signal” by a booby having little food to divulge. Boobies loaded with forage do not honk because the call could trigger regurgitation. Thus, frigatebirds harass with escalation only non-honking boobies. The …


Relative Abundance, Seasonal Occurrence, And Distribution Of Marine Birds In The Northern Gulf Of Mexico, J. Christopher Haney, Pamela E. Michael, Jeffrey S. Gleason, Randy R. Wilson, Yvan G. Satgé, Kathy M. Hixson, Patrick G.R. Jodice Jul 2025

Relative Abundance, Seasonal Occurrence, And Distribution Of Marine Birds In The Northern Gulf Of Mexico, J. Christopher Haney, Pamela E. Michael, Jeffrey S. Gleason, Randy R. Wilson, Yvan G. Satgé, Kathy M. Hixson, Patrick G.R. Jodice

Marine Ornithology

Marine birds in the U.S. Gulf of Mexico have long been poorly studied. Given statutory obligations to protect migratory birds and endangered species, three broad-scale vessel and aerial programs initiated since 2010 have now surveyed the entire northern Gulf. Vessel coverage alone exceeds 700 d and 74,000 km of observer effort using 300-m strip transects. We supplemented these survey data with earlier, smaller-scale studies, eBird checklists, literature reviews, and other less accessible sources to create snapshot summaries of relative abundance, seasonal occurrence, and regional distribution for 117 taxa of marine and water birds reported from the northern Gulf (113 of …


Status Of Craveri’S Murrelet Synthliboramphus Craveri In The Midriff Islands, Gulf Of California, Mexico, Francisco Jaime Martínez Reyes, Lauren A. Dolinski, Lorayne R. Meltzer, Paulina De L. Camarena Gomez, Noah L. Oas Jul 2025

Status Of Craveri’S Murrelet Synthliboramphus Craveri In The Midriff Islands, Gulf Of California, Mexico, Francisco Jaime Martínez Reyes, Lauren A. Dolinski, Lorayne R. Meltzer, Paulina De L. Camarena Gomez, Noah L. Oas

Marine Ornithology

The Craveri's Murrelet Synthliboramphus craveri is an endangered seabird (family Alcidae) endemic to northwestern Mexico, where it breeds on rocky islands throughout the Gulf of California (GOC). Nesting records are scarce for most of these islands, and much of the available information relies on historical data collected more than 50 years ago. Beginning in 2009 through to 2023, we performed intermittent nest searches on five islands in the Midriff Islands of the GOC. Starting in 2018 on Alcatraz Island and starting in 2022 on San Pedro Mártir Island, we monitored nests to determine average clutch size and hatching success. We …


Nape Coloration Varies With Sex, Not Age, Among Great Shearwaters Ardenna Gravis, Ewan D. Wakefield, Anna R. Robuck, Kevin D. Powers, Robert A. Ronconi, Peter G. Ryan, David N. Wiley Jul 2025

Nape Coloration Varies With Sex, Not Age, Among Great Shearwaters Ardenna Gravis, Ewan D. Wakefield, Anna R. Robuck, Kevin D. Powers, Robert A. Ronconi, Peter G. Ryan, David N. Wiley

Marine Ornithology

Most petrels (family Procellariidae) exhibit little or no obvious variation in plumage with age or sex, either because plumage performs no sexual function or does so in a way poorly perceptible to humans. This limits the inferences that can be made from visual observations of petrels at sea. However, it has been suggested that nape coloration of Great Shearwaters Ardenna gravis whitens with age. Here we test this supposition using observations of known-age-class individuals. We necropsied birds bycaught around Gough Island, a major breeding colony in the South Atlantic Ocean, and in Massachusetts Bay, a wintering area off the northeastern …


Spatial And Temporal Variation Of Beached Birds In Northern Argentine Patagonia, Victoria Magdalena Pizá, Patricio Javier Pereyra, Juan Pablo Seco Pon Jul 2025

Spatial And Temporal Variation Of Beached Birds In Northern Argentine Patagonia, Victoria Magdalena Pizá, Patricio Javier Pereyra, Juan Pablo Seco Pon

Marine Ornithology

Beached birds on marine coastal beaches, along with other megafauna, are a valuable source of biological information, offering insights into species occurrence and factors that negatively affect their populations. The main objective of this study was to evaluate the spatial and temporal variation, and species composition, of coastal and marine birds found on sandy beaches in the Bahía de San Antonio Protected Natural Area (Río Negro Province, Argentina), and to relate resulting species abundance and richness to oceanographic and environmental variables. A biweekly survey was carried out over two years (2020-2022), during which 672 beached birds were recorded. The overall …


Thick-Billed Murres Uria Lomvia At Cape Parry, Northwest Territories: Core-Use Areas, Morphometrics And Chick Diets, Rosana Paredes, Stephen, J. Insley, Sebastian Luque, Piia Kortsalo Jul 2025

Thick-Billed Murres Uria Lomvia At Cape Parry, Northwest Territories: Core-Use Areas, Morphometrics And Chick Diets, Rosana Paredes, Stephen, J. Insley, Sebastian Luque, Piia Kortsalo

Marine Ornithology

Cape Parry is home to the only colony of Thick-billed Murres Uria lomvia in the western Canadian Arctic, but ecological information for this small, isolated population is lacking. To address this information gap, we investigated the spatial distribution, diving behaviour, diet, and morphometrics of male and female Cape Parry Thick-billed Murres during the breeding season. We tracked 23 chick-rearing adults (seven females and 16 males) using Global Positioning System (GPS) tags with depth sensors (2021) and collected chick diet data (2021, 2022) using observations and photos. Cape Parry murres foraged relatively close to the colony (4.5 ± 3.3 km) and …


Comparison Of Offspring Growth Models In Atlantic Puffins Fratercula Arctica , Katja H. Kochvar, Raul Zabala Belenguer, Pierre-Paul Bitton Jul 2025

Comparison Of Offspring Growth Models In Atlantic Puffins Fratercula Arctica , Katja H. Kochvar, Raul Zabala Belenguer, Pierre-Paul Bitton

Marine Ornithology

Growth of morphological traits in the offspring of many seabirds, including Atlantic Puffins Fratercula arctica, has typically been characterized by linear models despite displaying nonlinear patterns. We assessed the fit of six typical avian growth models to measurements of puffling mass, wing length, and tenth primary length. Across all three biometrics, the first- and second-best performing models were nonlinear (i.e., quadratic, logistic, extreme value function); these models were then used to generate separate growth curves for individual pufflings and extract easily interpretable and comparable parameter estimates. We recommend the reported models in future studies incorporating metrics of puffling growth and …


Breeding Season Movements Of Aleutian Terns Onychoprion Aleuticus: Implications For Population Assessment And Monitoring, Kelly Nesvacil, Grey W. Pendleton, John P. Skinner, Susan Oehlers, Jeff Mondragon, Donald E. Lyons Jul 2025

Breeding Season Movements Of Aleutian Terns Onychoprion Aleuticus: Implications For Population Assessment And Monitoring, Kelly Nesvacil, Grey W. Pendleton, John P. Skinner, Susan Oehlers, Jeff Mondragon, Donald E. Lyons

Marine Ornithology

In 2017 and 2018, satellite transmitters were deployed (n2017 = 13, n2018 = 14) on Aleutian Terns Onychoprion aleuticus in two areas of Alaska, USA, to investigate breeding season movements and temporal patterns of colony activity. The effort was intended to aid in the development of a large-scale population-assessment framework. Across the two years, we observed dispersal to seven confirmed or potential (putative) colonies, none of which were previously documented, ranging in distance from 0.4 to 64.2 km from tag deployment sites. Although most terns did not associate with any known colonies during the breeding season, several individuals from the …


Modeling Breeding Habitat Preferences Of Tahiti Petrel Pseudobulweria Rostrata On Ta‘Ū, American Samoa, A. J. Titmus, C. A. Lepczyk Jul 2025

Modeling Breeding Habitat Preferences Of Tahiti Petrel Pseudobulweria Rostrata On Ta‘Ū, American Samoa, A. J. Titmus, C. A. Lepczyk

Marine Ornithology

Understanding the prevalence and use of breeding habitat of seabird species is important for evaluating appropriate conservation and management strategies. Seabirds are one taxonomic group for which we have relatively few species distribution studies, particularly on remote islands. To address this limitation, the goals of this study were to (1) build and use a species distribution model to identify which differences in habitat structure, physical characteristics, and environmental conditions affect Tahiti Petrel Pseudobulweria rostrata nesting presence on the island of Ta‘ū, American Samoa; and (2) evaluate how important nesting habitat characteristics can identify the fine-scale extent and location of suitable …


Technological Evolution Generates New Answers And New Ways Forward: A Progress Report From The First Decade At The Karlsö Auk Lab, Jonas Hentati-Sundberg, Per-Arvid Berglund, Agnes B. Olin, Aron Hejdström, Henrik Österblom, Astrid A. Carlsen, Quentin Queiros, Olof Olsson Jul 2025

Technological Evolution Generates New Answers And New Ways Forward: A Progress Report From The First Decade At The Karlsö Auk Lab, Jonas Hentati-Sundberg, Per-Arvid Berglund, Agnes B. Olin, Aron Hejdström, Henrik Österblom, Astrid A. Carlsen, Quentin Queiros, Olof Olsson

Marine Ornithology

In 2008, we built an artificial nesting construction for Common Murres Uria aalge, the Karlsö Auk Lab, on an island in the Baltic Sea (Hentati-Sundberg et al., 2012). The aim was to create an environment in which the birds could be readily monitored and accessed, and technological equipment easily installed. In this current paper, we report on murre recruitment to the Auk Lab over the first decade, assess the performance of the birds living on the lab compared to natural cliff ledges, and revisit the original research questions. We conclude that the tremendous developments in sensor technology (video surveillance, automated …

Mixed Metrics And The Need To Adjust Remote-Sensing Data In The Evaluation Of Key Biodiversity Areas For Colonial-Nesting Seabirds: An Example With Glaucous-Winged Gulls Larus Glaucescens, Michael S. Rodway, Douglas F. Bertram, Lindsay A.R. Lalach Jul 2025

Mixed Metrics And The Need To Adjust Remote-Sensing Data In The Evaluation Of Key Biodiversity Areas For Colonial-Nesting Seabirds: An Example With Glaucous-Winged Gulls Larus Glaucescens, Michael S. Rodway, Douglas F. Bertram, Lindsay A.R. Lalach

Marine Ornithology

Conservation initiatives such as the Key Biodiversity Areas (KBA) Programme use standardized criteria based on estimates of species abundance to identify critical habitats. They therefore depend on accurate estimates of population sizes for target species. It is essential that the metrics used to measure abundance at a candidate site are consistent with those used to estimate total abundance at national or global scales, because only then can it be determined whether abundance at a site meets threshold criteria. Imagery gathered by remotely piloted aircraft systems (RPAS, or drones) has rapidly become a tool for determining abundance of surface-nesting seabirds and, …


Updated Distribution And Population Dynamics Of Magellanic Penguin Spheniscus Magellanicus Colonies In The Strait Of Magellan, Chile, Manuel Ochoa-Sánchez, Jorge Acevedo, Claudio Moraga, Katherine Gaete, Pedro Valenzuela, Valeria Souza, Eliana Paola Acuña Gomez Jul 2025

Updated Distribution And Population Dynamics Of Magellanic Penguin Spheniscus Magellanicus Colonies In The Strait Of Magellan, Chile, Manuel Ochoa-Sánchez, Jorge Acevedo, Claudio Moraga, Katherine Gaete, Pedro Valenzuela, Valeria Souza, Eliana Paola Acuña Gomez

Marine Ornithology

The Magellanic Penguin Spheniscus magellanicus exhibits a broad latitudinal distribution in southern South America. However, the locations of many breeding colonies remain poorly known on the Pacific side, particularly in the southernmost region. Here, we provide information for six Magellanic Penguin colonies in the Strait of Magellan and adjacent waters that have been known by the local community for years but were unknown in the scientific literature until now: Rupert Islet, Tuckers Islet 1, Tuckers Islet 2, James Island 1, James Island 2, and Monmouth Island. These locations differ in population size and in vegetation coverage: most colonies are characterized …

Mesopelagic Diet As Pathway Of High Mercury Levels In Body Feathers Of The Endangered Black-Capped Petrel (Diablotin) Pterodroma Hasitata, Yvan G. Satgé, Sarah E. Janssen, Gemma Clucas, Ernst Rupp, J. Brian Patteson, Patrick G.R. Jodice

Marine Ornithology

The Diablotin or Black-capped Petrel Pterodroma hasitata is an endangered gadfly petrel found in the western North Atlantic, Caribbean Sea, and northern Gulf of Mexico. An estimated ~2000 pairs nest at five known sites on Hispaniola, Greater Antilles, although only 120 nests have been located to date. We collected breast feathers and feces from breeding adults in the Dominican Republic in April 2018 (n = 10) and from non-breeding adults at sea offshore of North Carolina, USA, in May 2019 (n = 10). We measured mercury burden in feathers and used fecal DNA metabarcoding to compare diets. We found higher …

Black Oystercatcher Haematopus Bachmani Productivity In California And Oregon And The Effects Of Nest Site And Environmental Covariates, Anna Weinstein, Joseph Liebezeit, Daniel Orr, Ryan D. Carle, Timothy D. Meehan

Marine Ornithology

Black Oystercatcher Haematopus bachmani is a species of conservation concern due to its small global population, reliance on somewhat restricted intertidal habitat, and vulnerability to climate change impacts. Concern for this species, along with a lack of demographic information from the southern portion of its range, gave rise to a community science project to monitor pair productivity, nest characteristics, and nest disturbance from 2012 through 2022 across three study regions in Oregon and California. A clear spatial gradient existed in productivity, with relatively low values in the southern region (0.37 fledged young per pair per year, 95% confidence interval [CI] …

Robert Kohley, Jessica Behnke, Brooke Mcfarland, Katherine Finney, Hob Osterlund, Julie Murphy, Angela Serota, Louise Barnfield, Yuka Green, Kim S. Rogers, Cathy Granholm

Marine Ornithology

In the 1960s and 1970s, Laysan Albatrosses Phoebastria immutabilis colonized several sites in the Pacific from which they had been extirpated or had not been known to nest previously, including the US Navy’s Pacific Missile Range Facility (PMRF) on Kaua‘i, Hawai‘i, USA, where they increased to become a bird aircraft strike hazard (BASH). To reduce their population at PMRF, albatross eggs were destroyed or removed as part of a BASH reduction program until 2005, when an alternate plan was devised by the Navy, US Fish and Wildlife Service, and US Department of Agriculture Wildlife Services, in which eggs from PMRF …

A Regionally Significant Population Of White-Tailed Tropicbirds Phaethon Lepturus On Kurehdhoo (Lhaviyani Atoll), Republic Of The Maldives, James C. Russell, Sebastian Steibl, Guy M.W. Stevens

Marine Ornithology

Coral atoll islands are important breeding sites for tropical seabird species, but on many of these islands, disturbances from humans and introduced mammals have extirpated breeding colonies. In the Republic of the Maldives (Indian Ocean), little published information exists on the location and extent of seabird breeding colonies. Here, we document what appears to be a regionally significant breeding site for White-tailed Tropicbirds Phaethon lepturus on Kurehdhoo, the northern-most inhabited island of Lhaviyani Atoll in the central Maldives. We systematically surveyed the entire island on two separate occasions, six months apart, to count the number of White-tailed Tropicbird nests, their …
