Household food wastage in Albania: causes, extent and implications
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2020-04-02)
Food waste (FW) is a very serious issue not only in ethical and social terms, but also given its economic and environmental impacts (cf. resource wastage and depletion). Recent data show that more than half of food wastage in the European Union is generated in households. FW is unfortunately not well addressed in Albania. For this reason, an exploratory online survey was carried out in the period August–November 2016 with 185 Albanians to analyse the causes, extent and implications of household food wastage in Albania. ...

Investigation of the functional synergy and involvement of different tRNA modifications in translational control
(2020-07-02)
Transfer RNAs are essential adapter molecules employed in the translational process and are highly modified all over their structure. Specific modification of the four canonical ribonucleotides (A, U, C, G) is accomplished by various proteins and/or protein complexes, ranging from simple isomerisations (e.g. Ψ) and methylations (e.g. m5C) up to complex chemical structures (e.g. mcm5s2U, ct6A). The functions of tRNA modifications are linked to the specific position and may influence translation by supporting the native ...

Caught in the Act: Predicting Cheating in Unproctored Knowledge Assessment
(2020-05-20)
Cheating is a serious threat in unproctored ability assessment, irrespective of countermeasures taken, anticipated consequences (high vs. low stakes), and test modality (paper-pencil vs. computer-based). In the present study, we examined the power of (a) self-report-based indicators (i.e., Honesty-Humility and Overclaiming scales), (b) test data (i.e., performance with extremely difficult items), and (c) para data (i.e., reaction times, switching between browser tabs) to predict participants’ cheating behavior. To ...

Antecedents, Interpretations and Consequences of Strategic Change: A Business Model Perspective
(2020-10-15)
Firms increasingly face challenges caused by changes in their environment like shifts in custom-er preferences, the development of new (digital) technologies, or threats by new, disruptive business models (BM). Firm survival and achieving long-term success often require a firm’s reaction to these challenges. Therefore, firms mostly engage in and initiate strategic change like business model innovation (BMI), a dynamic process that alters strategies, structures, and iden-tities and involves various actors. Due to the ...

Optimization of cassava dried noodle using hydrocolloid and protein isolates: a tropical noodle
(2020-11-29)
Cassava flour has the potential to be used as a substituent of flour in making dry noodles. This study aims to obtain the optimum formulation of flour, hydrocolloid content and protein isolate content. Formula optimization of cassava noodle has been done by using two types of cassava flour: native and pre-gelatinization, adding additional food additives such as hydrocolloid (xanthan gum and konjac glucomannan) and pea protein isolate. The design of the formulation and optimization is done by D-optimal combined design ...

On the Trail of Creativity: Dimensionality of Divergent Thinking and its Relation with Cognitive Abilities, Personality, and Insight
(2020-12-02)
Divergent thinking (DT) is an important constituent of creativity that captures aspects of fluency and originality. The literature lacks multivariate studies that report relationships between DT and its aspects with relevant covariates, such as cognitive abilities, personality traits (e.g. openness), and insight. In two multivariate studies (N = 152 and N = 298), we evaluate competing measurement models for a variety of DT tests and examine the relationship between DT and established cognitive abilities, personality ...

Seasonal variation in mycoflora associated with asymptomatic maize grain from small-holder farms in two provinces of South Africa
(2020-11-27)
Seed quality plays an important role in the establishment of healthy crop stands. The aim of this study was to identify the mycoflora associated with maize grain collected over two growing seasons, one experiencing severe drought, from small-holder farms across KwaZulu-Natal (KZN) and the Eastern Cape (EC), two important provinces with maize producing small-holder farmers in South Africa. Asymptomatic maize ears were collected at harvest during two maize growing seasons from farms located in Hlanganani (KZN), ...

A comparison of individual and group behavior in a competition with cheating opportunities
(2020)
While it is well established that individuals and groups make different economic decisions, the reasons for the behavioral differences are still not fully understood. We experimentally compare individual and group behavior in a competitive setting where cheating can be used to outperform the competitor. Our design allows us to exogenously control for the type of the decision maker, the type of the competitor, and whether the competitor is able to cheat or not. The results show that there is much more cheating in ...

Process optimisation and development of non-invasive monitoring approaches for the drying of apples
(2020)
Drying is of great importance particularly in the field of preserving agricultural products. It plays a very critical role by delivering nutrient rich products with a long shelf-life as well as help to combat food loss. Drying processing techniques have changed and improved significantly over time, helping to ensure food abundance in both aesthetical and nutritional regards. Convective hot air drying is one of the most common technique practiced by 85 % of industries. It can be easily applied in the remote areas of ...
