Abstract. Factorial survey experiments are increasingly used in the social sciences to investigate behavioral intentions. The measurement of self-reported behavioral intentions with factorial survey experiments frequently assumes that the determinants of intended behavior affect actual behavior in a similar way. We critically investigate this fundamental assumption using the misdirected email technique. Student participants of a survey were randomly assigned to a field experiment or a survey experiment. The email informs the recipient about the reception of a scholarship with varying stakes (full-time vs. book) and recipient’s names (German vs. Arabic). In the survey experiment, respondents saw an image of the same email. This validation design ensured a high level of correspondence between units, settings, and treatments across both studies. Results reveal that while the frequencies of self-reported intentions and actual behavior deviate, treatments show similar relative effects. Hence, although further research on this topic is needed, this study suggests that determinants of behavior might be inferred from behavioral intentions measured with survey experiments.

This paper deals with the structural identifiability and the identification of the parameters of a reduced order model used for control of a single reactor activated sludge process doing nitrification and denitrification. This reduced order model is splitted into two submodels, one 3-dimensional state submodel in aerobic conditions and one 2-dimensional state submodel in anoxic conditions. The identifiability analysis is based on on-line oxygen and nitrate concentrations data. It has been shown that the reduced order model is structurally identifiable. The parameter identification has been carried out by using the simplex method of Nelder and Mead. Simulation results performed over a range of six hours (two aerobic/anoxic cycles), show that there exists a good fit between the simulated solution and the actual behavior of a lab scale pilot plant.

Traveling to die in another country is a morbid, but pertinent, topic that remains underresearched in tourism. This project aims to address this research gap by examining the underlying motivations of actual individual travelers who have travelled to Switzerland as their final life destination to commit physician-assisted suicide (PAS). Using documentaries from major news channels, content analysis was conducted to systematically examine interviews conducted with actual PAS travelers ( n = 26) before they ended their life legally through PAS in Switzerland. An extension of the theory of planned behavior with anticipated guilt was commissioned as the theoretical lens to investigate the actual behavior of travelers who have committed PAS. A total of three key attitudes, three social groups, and four perceived constraints were identified. Results identified putting an end to suffering and to die with dignity as key attitudinal items influencing PAS behavior. The reference groups of family and relatives emerged as key salient normative groups. With regard to perceived difficulties, lack of access to facilities and high financial costs were key constraints in the decision to commit PAS. A key contribution of this research found evidence of anticipated guilt as an additional theory of planned behavior variable in actual PAS behavior.

PurposeThis paper builds on and extends the theory of planned behavior (TPB) by examining empirically the underlying mechanism through which red tape is associated with employee change-supportive intention (CSI). It investigates red tape as an antecedent of CSI and examines the mediation role of change-related attitude, subjective norm and perceived behavioral control (PBC) in the relationship between red tape and CSI.Design/methodology/approachTo test the study's hypotheses, cross-sectional data were collected from 183 employees working at a public organization in the Kurdistan Region of Iraq that was going through a major change. Regression analyses and the PROCESS macro for SPSS were used.FindingsConsistent with our expectations, the results indicate that red tape negatively predicts CSI. Red tape also predicts change-related attitude, subjective norm and PBC, which consequently predict CSI. The results also reveal that the relationship between red tape and CSI is mediated by change-related attitude and subjective norm.Research limitations/implicationsThe study is limited in using cross-sectional data at a point in time and in investigating intention only, rather than actual behavior.Originality/valueWhile prior work shows that red tape is a relevant factor that may affect employee responses to change in public sector, the psychological processes on which this relationship is based are still not fully explained. Therefore, this is the first study that aims to shed some light on this relationship.

The results of a first experimental research program on masonry vaults strengthened by means of GFRP meshes embedded in a thin layer of lime mortar, are herein presented. The tests were designed to reproduce the pattern of a transversal horizontal load proportional to the vault self-weight. The typical simplified loading patterns generally used for the experimental tests concern concentrated vertical loads at the crown section or at 1/4 of the span, but some numerical investigations evidenced that these configurations are not able to reproduce the actual behavior and the effectiveness of the reinforcement. So a specific rig was designed to apply the horizontal load pattern.Solid brick masonry barrel vaults were considered (thickness 120 mm, arch span 4000 mm, arch rise/radius = 0.75). Three quasi-static cyclic tests were performed: the first concerned an unreinforced vault, the second a vault reinforced at the extrados through the application of a mortar coating reinforced with a GFRP mesh and the third reinforced at the intrados surface with the same technique. The experimental results demonstrated the technique effectiveness and the important increment of ductility of the vaults.

In recent years, post-consumer textile waste has become an important issue that attracts attention from activists, scientists and the media. The production and use of clothing has more than doubled in the last fifteen years due to declining costs, streamlined operations and rising consumption under the influence of fast fashion. According to research, the average European buys as much as 26 kg of textiles each year and discards 11 kg, while a very small share of post-consumer textile waste is recycled. This article presents the findings of a study on household textile waste in the capital of Ljubljana. The research showed that despite the significant declarative environmental awareness of people for sustainable behavior in the field of textile waste, the share of those decreases with exposure to actual behavior. However, there are few people who are completely uninterested in reducing textile waste, as most people are aware of the problem and pay more and more attention to it. The authors study the management of textile waste and its creation by the inhabitants of Ljubljana in the broader context of the influences of fast fashion, as well as the cultural specifics of the Slovenian society.

Information Exchange (IE) is an important area of research in Information System (IS), yet there is a lack of theory that explains it. Existing studies usually borrow different theories from other fields to explain IE, but these theories describe the aspects that are associated with IE, not the actual behavior of IE. Additionally, a framework that guides the design of an IE platform to support IE among multiple stakeholders with the purpose of improving the decision-making process does not exist. To address these literature gaps, this dissertation first proposes a theory of Information Exchange (ToIE) to explain IE behavior and its impact on the decision-making process among multi-stakeholders. A qualitative evaluation of ToIE demonstrates that it meets the virtues of a good theory. Second, this dissertation develops an Information Exchange Decision Support (IEDS) framework that can guide the design of IE platforms for multiple stakeholders. The qualitative evaluation shows that the IEDS framework is useful for identifying the stakeholders, specifying the needed information to be exchanged, and maintaining the needed system factors necessary for IE. The IEDS framework is further instantiated to an IE platform named SES-IE. The SES-IE platform is a web-based application that facilitates the information exchange among scholarship organizations, employers, and students, and supports their decision-making process. The SES-IE platform was evaluated using a mixed-methods approach to measure the usability, usefulness, and satisfaction of the system. The successful instantiation of the SES-IE platform shows that the IEDS framework is useful for building an effective IE platform. This dissertation makes theoretical and practical contributions.
