This article reports results of a field experiment in which two hundred e-mails were sent to authors of recent articles in economics that had promised to send the interested reader supplementary material, such as alternative econometric specifications, "upon request." The e-mails were sent either by a researcher affiliated at Columbia University, New York or the University of Warsaw, Poland; furthermore, the authors' position (assistant professor) was specified in half the e-mails only. Overall, 64% of the approached authors responded to our message, of which two thirds (44% of the entire sample) delivered the requested materials. The frequency and speed of responding and delivering were very weakly affected by the position and affiliation of the sender. Gender or affiliation of the author, number of citations or journal impact factor or the type of object in question seemed to make no difference. However, authors of published articles were much more likely to share than authors of working papers.  相似文献

This article presents the results of an empirically based research study that addresses two objectives: to examine the affiliations of authors of articles published in social work journals, and to determine if there is an increase in each category of affiliation over time; and to examine if there is an increase in the number of multiple authorships of articles in journals over time. The findings support the contention that university and college professors publish more than practitioners and they also account for the increasing amount of literature published. Additionally, 17% of all articles were co-authored with only a slight increase in co-authorship over time.  相似文献

Non‐governmental organizations (NGOs) and the government of Nepal have made some effort to reduce poverty in Nepal by creating women's affiliation groups, some of which are micro‐credit organizations. Using capabilities as defined by Amartya Sen (Development as freedom, Oxford University Press, New Delhi, 2000), which includes employment opportunities, women's ownership in productive resources such as land and/or homes, educational opportunities, and women's participation in decision‐making in the family, this study evaluated the extent to which women's ethnic group or caste affiliation affected a woman's likelihood of being empowered by participation in these groups. We analyzed a sample of 8,973 women which was taken from the 2011 Nepal Demographic and Health Survey. Previous research has demonstrated that participation in gender‐based groups is correlated with higher economic status. This study adds to the literature on women's affiliation groups by investigating the impact of structural factors, such as caste and ethnicity, on women's self‐help group participation (women's groups and credit groups).  相似文献

This study aimed to investigate the current status and policy of Conflict of interest (COI) reporting in biomedical journals in China. Thirty Chinese-language medical journals and 37 English-language biomedical journals indexed by Journal Citation Reports categories were included into this study. These 67 journals were all published in China. All articles published in the most recent two issues were checked for identifying the disclosure statement in the text or not. Twenty-one of 30 (70%) Chinese-language journals required a disclosure of author’s potential COI. No journals require editors or referees to disclose the conflicts of interest to the readers. In total, 1,212 publications in Chinese-language were evaluated. Only two journals reported COI in their publications. For the 37 English-language journals, 32 (86.5%) required author’s potential COI disclosure, and four of them required only research articles or original articles to disclose COI. A total of 1,170 publications were evaluated. Among them, 50% editorials, 79.3% review articles, and 73.6% original articles reported presence or absence of COI. In our studied journals, the percentage of the policies requiring author COI disclosure is still low. Biomedical journals published in China should enforce COI disclosure policies to authors, editors, and referees.  相似文献

The syntax or codes used to fit Structural Equation Models (SEMs) convey valuable information on model specifications and the manner in which SEMs are estimated. We requested SEM syntaxes from a random sample of 229 articles (published in 1998–2013) that ran SEMs using LISREL, AMOS, or Mplus. After exchanging over 500 emails, we ended up obtaining a meagre 57 syntaxes used in these articles (24.9% of syntaxes we requested). Results considering the 129 (corresponding) authors who replied to our request showed that the odds of the syntax being lost increased by 21% per year passed since publication of the article, while the odds of actually obtaining a syntax dropped by 13% per year. So SEM syntaxes that are crucial for reproducibility and for correcting errors in the running and reporting of SEMs are often unavailable and get lost rapidly. The preferred solution is mandatory sharing of SEM syntaxes alongside articles or in data repositories.  相似文献

ABSTRACT

Using a data set combining two surveys that were conducted by Birzeit University in Palestine, the study investigates the role that trust in government plays in the provision of social services in Palestine (N= 1,314). The relationship between trust in government and selected sociodemographic characteristics is also explored. Results from the bivariate and regression analyses performed reveal that perceived trust in government is significantly related to government performance and a respondent's gender, income, education, and political affiliation. Implications for practice and future research are discussed.  相似文献

Correspondence should be sent to Dr. Peter Huxley, Mental Health Social Work Research Unit, Department of Psychiatry, Manchester University, Stopford Building, Oxford Road, Manchester M13 9PT. Summary Of 158 clients referred to two area offices and six generalpractice attached social workers, 141 weré interviewedusing standardized social and psychiatric research interviews.The General Health Questionnaire (GHQ) was completed by 138clients. Their social worker completed the Case Review Form.Scores of 5 or more on the PSE Index of Definition (for theclient) were used to indicate psychiatric caseness. Using IDscores of 5 or more, 53% of the sample were identified as ‘cases’.The GHQ (cut-off 4/5) identified 73% of the clients as cases;and the GHQ (cut-off 10/11) identified 51% cases. Morbidity was significantly greater in the general practicesetting. Social workers' judgement (about the presence or absenceof mental illness/emotional disorder) was not significantlybetter than chance in the identification of specific disorders,but was significant in relation to the whole sample. The results are discussed and further studies are being conductedusing more sophisticated judgements of ’caseness’,and extending the enquiry beyond an inner city population.  相似文献

The importance of transparency with financial ties in biomedical research is widely recognized, and most peer-reviewed journals require declarations of Conflicts of Interest (COI). Nonetheless, variability in the consistency of declarations of COI has been sparsely assessed. To assess consistency and rates of COI declarations in the ophthalmic literature and the effectiveness of journal COI policies. We analyzed consistency and completeness of declaration of COI in the ophthalmic literature and compared the levels of completeness to specific journal requirements. Six-hundred forty-two peer reviewed articles satisfied the inclusion criteria. In 64%, COIs were unreported, in 25% declaration of COI was incomplete, and 11% of the articles reviewed had complete declaration of COI. Of the 33 journals in which the most frequently published authors’ articles appeared, 10 required the authors to complete the International Committee of Medical Journal Editors (ICMJE) form or an equivalent form, but this did not affect the rates of COI declaration. In a random sampling of the most frequently published authors in the field of ophthalmology, declaration of COI was low and highly inconsistent. Requiring a standardized COI form has no significant effect on the rate of accurate COI reporting. Our findings lend support to the growing body of literature that shows that journals and editors may need to take a more active role in ensuring accurate and consistent COI reporting.  相似文献

Violations of dominance in pricing judgments   总被引:1,自引:1,他引:0  
The dominance principle states that the judged price of gamble A should be equal to or greater than the judged price of gamble B whenever A's outcomes are equal to or better than the corresponding outcomes of B, holding everything else constant. Subjects often violate the dominance principle by assigning a higher price to a gamble with some probability of winning a positive amount, Y, otherwise zero, than to a superior gamble with the same chances of winning Y, otherwise winning X. Violations also occur with losses. Results are consistent with a configural-weight theory in which the decision weight for each outcome depends on the rank of the outcome with respect to the other outcomes in the lottery and the value of the outcome (zero vs. nonzero).The authors thank Shi-jie Chang, Duncan Luce, and Lisa Ordóñez for comments on an earlier draft. This research was supported by a National Science Foundation grant to the first author (BNS-8451368).

The effects of stability versus change in adolescents' affiliation with delinquent or nondelinquent friends over a two-year period (T1–T2) on delinquent behavior one year later (T3) were examined. In addition, T1 predictors of stability and change in the affiliation with delinquent or nondelinquent friends from T1 to T2 were assessed. Participants were 152 adolescents (77 girls, mean age 12.1 years at T1). Friends' delinquent behavior was assessed through friends' self-reports. The T1 predictor variables included adolescents' own delinquent behavior, attitude toward delinquent behavior, and parental monitoring. Adolescents' friendship affiliations at T2, but not at T1, predicted delinquent behavior at T3, suggesting a recency effect of friendship affiliation. Attitude toward delinquent behavior at T1 was the main predictor of stability versus change in adolescents' affiliation with delinquent or nondelinquent friends from T1 to T2.  相似文献

This research aimed to clarify the correlates of gang awareness in inner city youth as a function of age, gender and peer group affiliation. It is proposed that the influence and hegemony of street gangs is a distinguishing feature of inner city neighborhoods, and that this influence is mediated by development. Participants (N = 489) were African American boys and girls from the 1st, 4th, and 7th grades in four inner city public schools. Students’ knowledge of gangs in the local community was determined. Social networks for 4th and 7th grade students were identified. Girls’ and boys’ familiarity with local gangs increased with age and differed by peer group affiliation. The relationship of gang familiarity to teacher and self‐ratings of aggression, popularity, and academic competence changed with age. These findings support the proposition that neighborhoods have nontrivial effects on social development, and these effects are likely to interact with developmental status and social affiliations.  相似文献

China has achieved a dramatic development in scientific research over the last few decades. However, just like many other countries, it has also seen a surge of scientific misconducts. With its expansion of international publications, retractions due to suspected research misconduct are also on the rise. A transcultural case study was conducted by investigating the perception of research misbehaviors by Chinese researchers compared to their Belgian Flemish colleagues. The study was designed to find out variation in research practices in different countries and to see how research was shaped and influenced by cultural contexts. An online questionnaire was sent to 3,236 researchers by e-mails and it received a response rate of 13.09%. They were asked to score 32 research misbehaviors on a 5-point scale. The findings suggested that compared to Flemish respondents, the Chinese had a significantly higher acceptance toward most research misbehaviors. To be more specific, the Chinese respondents felt less unacceptable toward behaviors violating such values as honesty, fairness, and verifiability than the Flemish, while their perceptions of behaviors that violated such values as responsibility, objectivity, and truth were not different compared to the Flemish. This case study implies that the Chinese research community is in an urgent need of training in responsible conduct of research and strong as well as sound guidelines for responsible research practices in place.  相似文献

Both the scientific community and the general public have expressed concern over scientific misconduct. The number of retracted articles has increased dramatically over the past 20 years and now comprises about .02% of the 2 million articles published each year. Retraction of publications available in large public databases can be analyzed as an objective measure for scientific misconduct and errors. In this project, we analyzed retractions of scientific publications using the Web of Science (WoS) and PubMed databases. We found that a power law is applicable to distributions of retracting authors and retracted publications with exponents of about ?.6 and ?3.0, respectively. Application of a power-law model for retracted publications implies that retraction is not a random event. Analysis of the retraction distributions suggests that a small fraction (1–2%) of retracting authors with ≧5 retractions are responsible for around 10% of retraction. The probabilities for their repeating retraction are calculated using a statistical model: 3–5% likelihood of repeat retraction for authors with a single retraction at five years after the latest retraction and 26–37% for authors with five retractions at five years after the latest retraction. By focusing on those with repeated retractions, this analysis could contribute to identification of measures to reduce such repetition of retractions.  相似文献

An introduction is provided to this Social Development Quartet in which the articles focus on parent emotion socialization in the context of psychopathology and risk. In two articles, the samples of children and/or adolescents have a psychiatric diagnosis [oppositional defiant disorder (ODD) or depressive disorder]. The other two articles feature samples in which children and families have experienced serious risks [exposure to inter‐parental violence (IPV) or maternal incarceration]. The articles in this Social Development Quartet extend our knowledge of the impact of parental emotion socialization practices to contexts in which children and parents experience higher than normative risks. The work reported in these articles builds upon research on emotion socialization in normative contexts, illustrating the buffering effects of supportive parenting as well as its limits.  相似文献

Objective. The objective of this article is to test Strömberg's (2001) prediction that newspapers will devote more space to costs of tariffs than to their benefits, using the recent steel tariff issue as a test case. Method. A content analysis was performed on a sample of 123 New York Times (NYT) and 177 Wall Street Journal (WSJ) articles published between January 1 and September 10, 2002. The articles were coded sentence by sentence for pro‐, anti‐, and neutral‐tariff content. Comments or information deemed supportive of the tariffs, that is, touting their benefits, were coded +1, while those emphasizing the costs of tariffs were coded –1. A statement that was neutral with regard to the tariff issue was coded 0. The proportion of sentences coded –1 was then compared with the proportion coded +1. Results. The coders found 395 sentences devoted to the negative impacts of steel tariffs versus 124 sentences devoted to their benefits out of a combined total of 3,207 sentences. The results also reveal a mild “slant” toward free trade in the WSJ relative to the NYT. In the WSJ, the proportion of lines criticizing tariffs (0.11) exceeds the proportion supporting tariffs (0.02) by a wider margin than in the NYT (0.13 vs. 0.06). Conclusions. This article provides empirical support for Strömberg's (2001) political economy model of the media. The model implies that mass media will weaken the power of special‐interest lobbies relative to unorganized interests. Specifically, the data support Strömberg's prediction that more newspaper space would be devoted to the costs of steel tariffs—which are widely dispersed—than to their benefits—which are narrowly targeted.  相似文献

In January 1990, a short letter was sent to the editor of the international medical journal, Pediatrics, to alert its readers that the standard, highly quoted paper by Singer and Ophaug on fluoride intake by infants, published in 1979 in the same journal, required revision/correction in order to protect one group of infants from receiving substantial overdoses of fluoride. This group comprises infants who are fed almost entirely on powdered formula which is reconstituted with fluoridated water.

The letter was based on the well‐established pediatric guidelines of water intake by infants and the fundamental toxicological principle of protecting groups at highest risk. It did not question the fluoridation of public water supplies. Nevertheless, the letter, together with a response to it by Ophaug, was rejected by the editor of Pediatrics, “due to a large backlog of articles.”; Following a protest, the letter was reviewed by three referees, two of whom conceded its main point, but was still not published.

In the present paper, the original, previously unpublished letter on fluoride intake by infants is first reproduced verbatim, and then the comments of the referees and editors are reported and examined. It is concluded that the most plausible explanation for the rejection of the letter is that it might assist the anti‐fluoridation movement. Another possible contributing explanation is that publication of the letter might reduce the status of the scholars who had defended the previous position and might be perceived to diminish the status of the journal.  相似文献

The "contemporary setting" was the midst of total war and its social and economic circumstances. The flavour is recaptured in a 1942 newsreel. The effect on members of the armed forces is examined. The reaction of the coalition government and the responses of the Conservative party and of the Labour party showed divisions within each, documented in archives of party conferences, current periodical articles, and interviews conducted in 1992 with expert witnesses Lord Longford (Frank Pakenham) and Lord Hailsham (Quintin Hogg). Beveridge's Liberal party affiliation is reasserted and reviewed. The report's influence on other European countries merits further investigation, as many governments and forces in exile were in Britain in 1942.  相似文献

Objectives. This article seeks to understand the development of partisanship among Asian Americans since a significant portion do not choose either major party affiliation, but select an independent or a truly nonpartisan status. With a rapidly growing Asian‐American population, examining its pattern for both partisan and nonpartisan identification has been ignored. This research took a developmental process in which acquisition of any partisan affiliation/identification is a critical juncture for Asian‐American political incorporation. Therefore, considering contributing factors that affect the acquisition of any partisan affiliation as a precursor to specific Asian‐American partisan affiliation/behaviors is our direction. Methods. Using a logistical regression model and data from the Pilot National Asian American Political Survey, a category of variables, including sociodemographic, Asian‐American subgroup status, U.S. political orientations and attitudes, and experiences with U.S. society, are used to understand a partisan and nonpartisan affiliation. Results. This study reveals that aspects of socioeconomic status, political attitudes, and immigrant experiences are important, in varying degrees (especially Asian subgroup status) to understand partisan acquisition for Asian Americans. More so, Asian‐American subgroups, persons with lower educational and income levels, and participants in the labor force are less likely to assume a partisan affiliation. Levels of interest in U.S. politics and length of time in the United States do contribute to a partisan affiliation. Conclusions. Viewing partisan affiliation as a developmental process is an important research avenue to approach the Asian‐American community. The inclusion of not only sociodemographic variables, but experiences and evaluation of the U.S. political system, as well as recognizing the political “culture” of Asian‐American subgroups, provides a more complete understanding of the partisan acquisition process.  相似文献
