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.

AbstractThe use of oleogels is an innovative and economical option for the technological development of some food products, among them ice creams. The aim of this study was to establish the best processing conditions to obtain an emulsion which form oleogels with the lowest ζ-potential and average droplet size (ADS) for use as ice cream base. Using surface response methodology (SRM), the effects of three numerical factors (microfluidization pressure, oil and whey protein concentration, WP) and four categorical factors (oil type, temperature, surfactant, and type of WP) on formation of emulsions were assessed. The response variables were ζ, ADS, polydispersity index (PDI), viscosity (η), hardness, cohesiveness and springiness. Additionally, a numerical optimization was performed. Two ice creams containing milk cream and oleogel, respectively were compared under the optimization conditions. Results suggest oleogels obtained from the microfluidization of whey and high oleic palm oil are viable for the replacement of cream in the production of ice cream.

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.
