This study explored whether early elementary school aged children’s externalizing problems impede academic functioning and foster negative social experiences such as peer victimization, thereby making these children vulnerable for developing internalizing problems and possibly increasing their externalizing problems. It also explored whether early internalizing problems contributed to an increase in externalizing problems. The study examined 1,558 Canadian children from ages 6 to 8 years. Externalizing and internalizing problems, peer victimization, and school achievement were assessed annually. Externalizing problems lead to academic underachievement and experiences of peer victimization. Academic underachievement and peer victimization, in turn, predicted increases in internalizing problems and in externalizing problems. These pathways applied equally to boys and girls. No links from internalizing to externalizing problems were found. 相似文献

Abstract The music business is facing hard times with declining CD sales and increasing piracy. Whereas the economic downturn is one reason for lower sales, the industry has decided to target the second factor, the fast diffusion of technologies such as CD burners and peer‐to‐peer networks like KaZaA allowing massive illegal distribution of music. Some labels focused on an offensive strategy to promote their artists. New services are being added to so called Enhanced CDs that create a new user experience. These CDs offer bonus content (i.e. videos, additional songs, pictures, or lyrics) stored directly on the CD that can be accessed on the PC. Other CDs offer (additionally) online access to actual bonus content or services (i.e. tour dates or news) if the CD is entered in the FC. The impact of these services on consumer experience has not yet been researched in depth and it remains unclear if consumers actually use the offered services on Enhanced CDs. The music label Arista has introduced several new albums on Enhanced CDs to the market providing more value to the user instead of reducing the utility by focusing only on copy protection. This article analyzes the usage of such services provided by Arista and focuses on Santana's new album “Shaman”;. Using a unique data set provided byfavakitty Media (Bandlirik) and Arista, we show for the first time what services are actually used by Santana fans and compare the results to albums of other artists such as TIC or Toni Braxton. Our results indicate that Enhanced CDs are used frequently by a relatively small group of fans, providing more value to the customer and creating a stronger relation between fans and artists. 相似文献

Results of an experiment about the influence of network television news coverage of combat in Iraq on viewers indicated that, compared with a control condition which featured news stories about combat operations in Iraq described by news anchors, news reports also featuring footage of combat operations increased viewer involvement levels about the war and reduced viewer support for continued military presence in Iraq. Television news footage of combat operations also reduced viewers' pride in U.S. military presence but did not affect other emotions. However, regardless of how news stories were packaged, women experienced greater emotional response to network news stories about combat operations than men. The results also shed light on the potential of inoculation to deflect such influence. 相似文献

Although the Internet features excess demand for media, especially movie downloads, the motion picture industry lacks sustainable business models for this market. An enriched form of the theory of planned behavior can identify drivers of consumer intentions to adopt a legal movie download service. Using a large data set, this study estimates structural equation model parameters. The magnitude of specific influences is subject to unobserved heterogeneity, according to a finite mixture approach with partial least squares estimation. Not only attitude, but also social influence, perceived technical feasibility, innovativeness, compatibility, and past behavior drive adoption decisions. 相似文献

This short report explores the quality of the care process for children with intellectual disabilities. A Delphi procedure was used to identify a set of indicators for the quality of the care process reflecting the perspectives of the care providers, the parents and the experts. The sample consisted of 59 individuals involved in different ways in the process of the caring for children with intellectual disabilities. The first round of the Delphi procedure resulted in 56 themes, distributed across four different phases of the care process. In the second round of the Delphi procedure, these themes were elaborated into 346 indicators that were, in turn, evaluated on their importance for the quality of the care process by the respondents. Finally, 328 indicators did meet the 85% criterion for consensus. Six themes proved to be relevant in all phases of care: transfer of information, report, consultation, attitude of care provider, respect and appointments. The operationalization of quality of care presented in this study points in the direction of actually measuring, monitoring and improving the quality of care for children with intellectual disabilities. 相似文献

Preconceptions of first‐year university students of the constituents of matter and the notions of acids and bases were investigated on a total of 400 students. The procedure used consisted of free interviews, semi‐structured interviews and questionnaires. It was found that the constituents of matter were well known to students, but that interactions between these constituents were either totally unknown or were the subject of severe misconceptions. The students’ knowledge tended to be qualitative and formal, with a worrying lack of connection with everyday life. 相似文献

IntroductionTwo new formulas, the Martin-Hopkins and the Sampson formula, were recently developed to overcome shortcomings of the Friedewald formula for calculating LDL-cholesterol. We aimed to compare the concordance of the two formulas with apolipoprotein B (apoB), a surrogate marker of the number of LDL particles.Materials and methodsIn a study of serum lipid data of 1179 patients who consulted the AZ St-Jan Hospital Bruges for cardiovascular risk assessment, the correlation and concordance of the Friedewald, Martin-Hopkins and Sampson formulas with apoB concentration, measured by immunonephelometry, were determined and compared.ResultsThe Martin-Hopkins formula showed significantly higher correlation coefficient than the Friedewald formula with apoB in the entire dataset and in patients with low LDL-cholesterol < 1.8 mmol/L. Both Martin-Hopkins and Sampson formulas yielded > 70% concordance of LDL-cholesterol with regard to treatment group classification based on population-equivalent thresholds of apoB in hypertriglyceridemic patients (2-4.5 mmol/L), with the highest concordance (75.6%) obtained using Martin-Hopkins formula vs. 60.5% with Friedewald formula.ConclusionThe Martin-Hopkins (and, to a lesser extent, Sampson) formula is more closely associated with the number of LDL particles than Friedewald formula. This, in combination with literature evidence of lesser accuracy of the Friedewald formula, is an argument to switch from Friedewald to a modified, improved formula. 相似文献
