Effective communication and emotional support of parturient women improve the outcome of childbirth. Reduction in Duration of labor, cesarean rate, use of anesthesia, and 5 minute Apgar Score less than 7 can achieve. This study was a part of a large mixed method study during 2013-2014. In this qualitative study, in-depth interviews were conducted with 32 participants (16 mother and 16 midwife), using semi-structured interviews. Participants were recruited by pur-posive sampling with maximum diversity in terms of age, occupation, education and etc. Educational hospital of Arak University of Medical Sciences was considered as the setting. Each interview was conducted at a private and convenient location and took about 30 to 45 minutes. Interviews were audio taped and transcribed verbatim. Conventional content analysis was done for data analysis. Interviews continued until data saturation was obtained. Data were coded in MAXQDA software (version 11). The main category emerged as “outcome” of midwife-mother relationship. Facilitating childbirth, positive experience, mental health promotion and improvement in quality of life were derived as subcategories. Good midwife-mother relationship could promote positive outcome in labour. Results could assist midwives in providing holistic quality care to mothers during labour, thus providing positive consequence in child birth. Also, results could provide a framework and guidance for policymakers to create appropriate context for the midwife-mother relationship in maternity care. 展开更多

Purpose:The research is undertaken to help the Chinese public libraries answer the growing needs for library services to the elderly.Based on an investigation of the current situation of the services to older adults in China and a comparative analysis of the services in the U.S.,we attempt to explore what improvements the Chinese public libraries can make to better serve the needs of older adults.Design/methodology/approach:We empirically analyzed the older adults services of 271public libraries in China from 2002 to 2011 via content analysis of both the print materials such as the regulations and policies released by these libraries and the related information on the libraries' websites and the Internet Web pages.Findings:Great strides have been made in the Chinese public libraries' services to older adults in constructing service systems,providing facilities and equipment,exploring cooperative programming,and planning diversified and regularly scheduled activities.Compared with American counterparts,however,the Chinese public libraries need to catch up in understanding the elderly people as library users,planning customized services,formulating service guidelines and evaluation systems,and working with other local agencies for cooperative programming for seniors in communities.Research limitations:It is hard to collect more data covering more geographical areas and longer periods of time.The content analysis of libraries' policies and regulations is a very rough approximation of the libraries' 'real' services.The study should be extended to visits to public libraries in the future.Practical implications:This study provides useful information for the Chinese library policymakers to formulate regulations and policies to provide services to older adults.Originality/value:To the best of our knowledge,the comprehensive survey reported in this paper is the first in-depth investigation of the current situation of public library services to older adults in China,providing the analysis framework for more in-depth surveys in the future. 展开更多

Content analysis of scientific papers emanating from Antarctic science research during the 25 years period (1980-- 2004) has been carried out using neural network based algorithm-CATPAC. A total of 10 942 research articles published in Science Citation Indexed (SCI) journals were used for the study. Normalized co-word matrix from 35 most-used significant words was used to study the semantic association between the words. Structural Equivalence blocks were constructed from these 35 most-used words. Four-block model solution was found to be optimum. The density table was dichotomized using the mean density of the table to derive the binary matrix, which was used to construct the network map. Network maps represent the thematic character of the blocks. The blocks showed preferred connection in establishing semantic relationship with the blocks, characterizing thematic composition of Antarctic science research. The analysis has provided an analytical framework for carrying out studies on the con- tent of scientific articles. The paper has shown the utility of co-word analysis in highlighting the important areas of research in Antarctic science. 展开更多

The aim of this exploratory study is to analyze the effectiveness of website communications regarding thermal tourism and to evaluate the website attributes of thermal tourism facilities in Turkey. In order to achieve this aim, seven main categories (contact information, general information, facility information, thermal/medical and wellness services information, surrounding area information, booking and external contracts information, and technical items) and 55 sub-items are identified. Then websites are analyzed with a content analysis method. One hundred and sixty four thermal facilities in Turkey could be listed and accepted as the population. Systematic sampling method was used with a sample size of 33 thermal facilities. After the frequency analysis, results showed that most of the thermal facilities do not have an efficient website management in Turkey. Although official websites are very critical tools for effective marketing communication, thermal facilities are utilizing only a small potential of their websites. 展开更多

The main purpose of this paper was to examine female roles portrayed by advertising. More specifically, the questions that motivated this research project were "What messages about women have been given to society through advertisement?" and "Have these portrayals been changed during the past decades?" The study consisted of a systematic content analysis of Brazilian commercials from 1973 to 2000. The population from which this sample was drawn consisted of Brazilian commercials which got an award in international and national festivals. A probabilistic sample procedure was employed. Ninety five pieces were selected. The categories and operational rules used in the study were developed based on previous research. This study has proposed that female images in advertising are depicted in three different ways: stereotyped, idealized, and plural portrayals. Our results have revealed that some specific images have changed, however, they continued to be stereotyped and idealized. 展开更多

Picture books are a staple in the kindergarten classroom for teaching content, social expectations, and the joy of reading. The purpose of this study is to explore the representation and depiction of multicultural families in children's picture books within kindergarten classroom libraries. Children's pictures books are a microcosm of today's society. They convey cultural messages and values about society, and help children learn about their heritage and the heritage of others. Children's literature is increasingly more reflective of diverse cultures. Children need to see themselves reflected in literature in order to see the lives of others, and in order to see themselves as able to transverse between groups and worlds. America (U.S.) has been and will always be a diverse nation. Likewise, the Republic of Korea (ROK) is quickly becoming a multicultural society as well, and the influx of multicultural families is growing exponentially. Books depicting this growing diversity can dispose of stereotypes that children may have about races other than their own. Children's literature is still not authentically portraying a multiethnic Korea. The results of this study show that children who interact with current picture books predominantly see Korean faces. Finding books depicting non-Korean characters, particularly books depicting culturally specific elements, is rare, although there are books depicting culturally neutral and generic characters However, although our classrooms are culturally and ethnically diverse, the books predominantly found in classrooms portray only one race. What does that tell our students? Seeing diverse populations in children's literature needs to become the norm, not the exception. 展开更多

This study used Ecopath model of the Jiaozhou Bay as an example to evaluate the effect of stomach sample size of three fish species on the projection of this model. The derived ecosystem indices were classified into three categories:(1) direct indices, like the trophic level of species, influenced by stomach sample size directly;(2)indirect indices, like ecology efficiency(EE) of invertebrates, influenced by the multiple prey-predator relationships;and(3) systemic indices, like total system throughout(TST), describing the status of the whole ecosystem. The influences of different stomach sample sizes on these indices were evaluated. The results suggest that systemic indices of the ecosystem model were robust to stomach sample sizes, whereas specific indices related to species were indicated to be with low accuracy and precision when stomach samples were insufficient.The indices became more uncertain when the stomach sample sizes varied for more species. This study enhances the understanding of how the quality of diet composition data influences ecosystem modeling outputs. The results can also guide the design of stomach content analysis for developing ecosystem models. 展开更多

Pictures books are one of the communication tools for talking with children about severe diseases. However, little research is available about the contents of picture books about cancer for children. Therefore, this study aimed to examine the contents of children’s picture books about cancer and explore the advantages and disadvantages of using picture books to communicate with children about cancer.<strong> Methods:</strong> We searched the picture books about cancer written for children aged under ten years old on the Amazon.com Web site on 5 July 2019 and hand-searched on the cancer-related institutes’ Web site. We extracted the texts of relevant picture books and conducted a content analysis of them. <strong>Results:</strong> We identified 2555 picture books and included 30 of them. We identified three main contents, 1) cancer-related knowledge, 2) impacts of cancer, and 3) dealing with cancer. These contents were written with simple words and illustrations. Some of them included the essential contents, which might be misunderstood by children.<strong> Conclusions:</strong> Picture books might be helpful for children to understand about cancer. However, as these books do not include all contents, it is necessary to select and use multiple books depending on the content which is wanted to tell the child. Further research should evaluate the impacts of these books as a communication tool when talking with children diagnosed with cancer. 展开更多

Aphids are phloem-feeding insects that reduce crop productivity due to feeding and transmission of plant viruses.When aphids disperse across the landscape to colonize new host plants,they will often probe on a wide variety of nonhost plants before settling on a host suitable for feeding and reproduction.There is limited understanding of the diversity of plants that aphids probe on within a landscape,and characterizing this diversity can help us better understand host use patterns of aphids.Here,we used gut content analysis(GCA)to identify plant genera that were probed by aphid vectors of potato virus Y(PVY).Aphids were trapped weekly near potato fields during the growing seasons of 2020 and 2021 in San Luis Valley in Colorado.High-throughput sequencing of plant barcoding genes,trnF and ITS2,from 200 individual alate(i.e.,winged)aphids representing nine vector species of PVY was performed using the PacBio sequencing platform,and sequences were identi-fied to genus using NCBI BLASTn.We found that 34.7%of aphids probed upon presumed PVY host plants and that two of the most frequently detected plant genera,Solanum and Brassica,represent important crops and weeds within the study region.We found that 75%of aphids frequently probed upon PVY nonhosts including many species that are outside of their reported host ranges.Additionally,19%of aphids probed upon more than one plant species.This study provides the first evidence from high-throughput molecular GCA of aphids and reveals host use patterns that are relevant for PVY epidemiology. 展开更多

The relationship between design and science in architecture continually receives attention from scholars,but to our knowledge,no substantial and systematic literature reviews have been undertaken to generate insights into how the relationship between the two has developed in recent times.As most of the related debate remains theoretical,this paper presents evidence acquired through content analysis of selected 782 peer-reviewed papers published in the last four decades,a period in which design requirements continue to grow in complexity and research efforts increasingly concentrate on design methods.In response,this study departs from the two keywords,architectural science and building science,and develops search strings to support examination of the relationship between science and architectural design since the 1980s,when research that addresses the building environment started to intensify.The analysis employs tools based on machine learning algorithms for text analytics in combination with traditional content analysis methods.The presented research method is fully replicable and stands as one of the contributions of this study.The findings capture the expansion of the research context concerned with the built environment through a careful selection of defining terms,and generate an informed discussion on how the role of science in the architectural design process has changed. 展开更多

Gut content analysis is a useful tool when studying arthropod predator-prey interactions. We used polymerase chain reaction (PCR) technique to examine how detection of prey DNA in the gut content of predators was influenced by digestion time and temperature. Such knowledge is critical before applying PCR-based gut content analysis to field collected predators. Larvae of the two-spotted ladybeetle (Adalia bipunctata L.) were fed with the bird cherry-oat aphid (Rhopalosiphum padi L.) at either 21℃ or 14℃. After consuming one aphid, the predators were allowed to digest the prey for a range of time periods up to 24 hours. The influence of temperature on A. bipunctata feeding behavior was also recorded. From the fed larvae, total DNA was extracted and PCR reactions with R. padi specific primers were run. The number ofA. bipunctata that tested positive for R. padi DNA was negatively related to the length of digestion time. Temperature influenced larval feeding behavior but did not have a significant effect on R. padi DNA detection. After pooling the data from both temperature treatments we estimated the time point when R. padi DNA could be amplified from 50% of the fed A. bipunctata by PCR to be 4.87 hours. With such a rapid decrease in prey DNA detection success, positive PCR reactions will most likely be the result of predation events occurring shortly before capture. If a defined digestion temperature range has proven not to influence prey detection, PCR data obtained from predators collected within that particular range can be interpreted in the same way. 展开更多

Although many existing movie recommender systems have investigated recommendation based on information such as clicks and tags, much less efforts have been made to explore the multimedia content of movies, which has potential information for the elicitation of the user's visual and musical preferences. In this paper, we explore the content from three media types (image, text, audio) and propose a novel multi-view semi-supervised movie recommendation method, which represents each media type as a view space for movies. The three views of movies are integrated to predict the rating values under the multi-view framework. ~rthermore, our method considers the casual users who rate limited movies. The algorithm enriches the user profile with a semi-supervised way when there are only few rating histories. Experiments indicate that the multimedia content analysis reveals the user's profile in a more comprehensive way. Different media types can be a complement to each other for movie recommendation. And the experimental results validate that our semi-supervised method can effectively enrich the user profile for recommendation with limited rating history. 展开更多

This study aims to explore how the topic of sustainability in Higher Education Institutions(HEI)has been addressed in the scientific literature.It presents a systematic literature review of peer-reviewed journal articles published between 1975 and 2019.After that,bibliometric and content analyses were performed in order to identify the behavior and evolution of the literature and identify the frequency with which they appear in the text,making it possible to raise replicable and valid inferences to the data.The results of this study indicate that the theme is emerging since the year 2010 and with a strong focus on qualitative studies,focused on critical theory.The results indicate that although studies involve the tripod environment,economy,and society,there is still a gap in studies that deal with specific issues to solve practical problems and that analyze the impacts from a more holistic perspective.The combination of methods made it possible to identify and interpret the articles in the selected sample,but based on results reported by other authors,with little room for quality control and integrity. 展开更多
