Activating the implementers: The role of organizational expectations, teacher beliefs, and motivation in bringing about reform

2019

Abstract Internationally the research community has been seeking a deeper understanding about how to shape the work of educators over decades of educational reforms. This study attempts to contribute to this understanding by answering: “What motivates educators to implement the Common Core State Standards (CCSS)?” Using data from all school educators in one highly diverse school district in California and structural equation modeling to investigate the relationships between teachers' CCSS-related action and associated organizational and individual factors, findings suggest both organizational (expectation) and intrinsic (motivations and beliefs) factors are directly and indirectly influenci…

Millenials’ intentions to book on Airbnb

2018

The sharing economy has witnessed a significant growth in recent years, enhanced by the development of online platforms. In particular, Airbnb has witnessed a significant worldwide year-on-year growth. Given the importance and popularity of Airbnb, it is crucial to examine which factors affect intentions to book on this website. This study proposes and tests a model based on the Theory of Reasoned Action, to examine millennials’ determinants of intentions to book on Airbnb. Based on two online surveys targeting millennials from Germany and China, the results show that intentions to book on Airbnb is mostly influenced by subjective norm, desire for unique accommodation and variety, attitude …

The impact of social media and offline influences on consumer behaviour. An analysis of the low-cost airline industry

2016

This study analyses the impact of social media as well as offline environments upon tourist online purchase and recommendation behaviour of low-cost airline services. Drawing on the Theory of Reasoned Action (TRA), this research considers the effect of offline social influences (interpersonal and external influences) and analyses online Consumer-to-Consumer (C2C) information exchanges as a driver of customer attitude towards online purchases. We propose that these factors improve online repurchase intentions and positive word-of-mouth communication (WOM and e-WOM) in low-cost settings. Using structural equation modelling, the conceptual model is tested with a sample of 441 Spanish Internet …

Recognition of Chip Forms by Means of Dynamic Force Spectrum Analysis

1993

In this study the ability to identify chip forms occurrs in the turning of austenitic stainless steel using dynamic force spectrum analysis has been tested. For this purpose the frequency spectra obtained from various metal cutting tests were recorded along with the static cutting forces. A dual channel analysis, based on the Fast Fourier Transform (FFT), was adopted to help identify the continuous/discontinuous (favourable/unfavourable) chip forming boundary. The results showed an acceptable correlation between the types of the frequency spectra and the types of chip forms. Finally, an original classification of the spectra obtained during turning of AISI 304 (DIN 1.4301) stainless steel i…

Modelling safety climate in the prediction of levels of safety activity

1998

Abstract This study examined the architecture of the relationships between components of organizational safety climate, including employee attitudes to safety issues and perceptions of the work environment, and related this to self-reported levels of safety activity. Data were collected from a large multinational manufacturing organization by questionnaire. A total of 915 valid questionnaires were returned and formed the basis for structural equation modelling and subsequent analyses. These data showed that a common structure, or architecture, of attitudes to safety issues and perceptions of the work environment could be constructed that explained levels of safety activity. The strength of …

Flexural Test on a Full-Scale 60-kW Wind Turbine-Tower Telescopic Steel Pipe

2019

A full-scale static test to failure was conducted on 6-m (236.22 in.)-long steel pipes constituting a segment of a telescopic wind tower with a 60-kW wind turbine. The diameter of the circular cross section of the steel pipes was 900 mm (35.43 in.), and the nominal thickness was 10 mm (0.39 in.). The steel grade was 355 MPa (51,488 psi). The tests were conducted in a force-controlled mode in a four-point bending test with a shear-to-span ratio of 2.05. The flexural limit states developed in the form of ovalization of the cross section and of local buckling. The buckling occurred in the plastic range because of the diameter-to-thickness ratio of the section. Although local buckling caused sl…

Modelling of Final Plastic Deformation in the Case of Continuous Straight-Edged Oblique Cutting

1992

This paper presents a complex oblique cutting model for the case of varying chip formation conditions and its practical application in relation to the results of degree of final plastic deformation in the primary shear zone is considered. A computer procedure for prediction of the shear angle is given and the place of the oblique cutting process among the results obtained previously is established.

Masonry structures subjected to tsunami loads: Modeling issues and application to a case study

2020

Abstract Tsunamis are among the most dangerous natural disasters for coastal areas experiencing tsunami hazard. One of the major concerns in the assessment of strategies for the risk mitigation is to estimate vulnerability of structures and infrastructures. However, reliable approaches for the evaluation of the structural capacity under tsunami loads are nowadays not always available for all the types of structures, especially masonry. On this aim, the paper deals with the modeling issues of 3D masonry structures subjected to tsunami loads and the effect on the structural behavior of different modeling approaches. First, a brief state of the art on the available studies is presented regardi…

Capturing methodological trends in mobile communication studies

2013

This study investigates methodological trends in mobile communication studies. The articles published over the past 20 years in five journals (Communication Research, Journal of Communication, Journal of Computer-Mediated Communication, New Media & Society, and Information, Communication & Society) are analysed. The results show that the quantitative and qualitative studies have increased while theoretical accounts have remained few. The quantitative approach is the most applied. The studied articles reflect a structural problem of science communication that stems from the lack of cumulativity of scientific results and cross-national analyses and from the standard length of articles that po…
