Not All Reviews are Equal - a Literature Review on Online Review Helpfulness
(Association for Information Systems, 2019)
The amount of online reviews is growing significantly. Between 2014 and 2017, the number of reviews for TripAdvisor grew by 300% and for Yelp by 208%. However, not all online reviews are equally valuable. Some reviews are perceived to be more helpful or trustworthy then others. Hence, plethora of scholars have investigated the role of online reviews and researched factors and characteristics determining its helpfulness. Nevertheless, mixed findings were found. Consequently, the purpose of our paper is to present a ...

Ergebnisse und Redundanz in der Diskussion um eWOM: Eine kritische Literaturauswertung
(Universität Paderborn, 2014)
Electronic Word-Of-Mouth (eWOM) und Online Rezensionen (OR) werden als einer der Schlüsselfaktoren für erfolgreichen E-Commerce identifiziert. Jedoch sind die beeinflussenden Motivationsfaktoren für das Verfassen sowie das Lesen von OR bis heute gesamtheitlich nur unzureichend untersucht. Die vorliegende Literaturauswertung sammelt die bisherigen Forschungsergebnisse mit dem Ansatz, ein möglichst breites Bild der Motive für eWOM-Aktivitäten zu geben. Das Ergebnis der extensiven Literaturanalyse zeigt, dass für ...

El discurso de los santos en Gonzalo de Berceo. Actos de habla y perfiles dialógicos desde la perspectiva de la pragmática histórica. In: Emilio Montero Cartelle
(Meubook, 2012)
Los textos hagiográficos de Gonzalo de Berceo son caracterizados con toda razón como textos marcados en gran medida por la representación mimética de la interacción dialógica. Esta representación dialógica abarca también la caracterización de los propios santos cuyas acciones ejemplares quedan ampliamente reflejadas en escenas de habla y diálogos. En mi análisis se enfocan actos de habla y perfiles dialógicos desde la perspectiva de la pragmática histórica. Las siguientes interpretaciones lingüísticas y filológicas ...

Multicomponent Injection Molding Of Thermoplastics And Liquid Silicone Rubber (LSR) – Either Cured By Heat Or UV Light
(Society of Plastics Engineers, 2016)
For processing thermally curing liquid silicone rubber (LSR) as well as UV light curing LSR for multicompo-nent injection molding with thermoplastics in an compa-rable way a processing center was designed and set into operation.
For the production of the multicomponent specimens a modular tool was designed. In there a thermoplastic plate gets molded on the one side, then gets transferred auto-matically by a robot system and gets overmolded by the silicone on the other side. The complete silicone side of the tool is ...

Influence Of The Fiber-Matrix-Interaction On The Fracture Behavior Of Regenerated Cellulose Fiber Reinforced Polypropylene
(Society of Plastics Engineers, 2017)
This investigation focuses on the fiber-matrix-interaction of man-made cellulose fibers (RCF) in a PP matrix with an additional MAPP content using an energetic evaluation of the single fiber pull-out test (SFPT). Furthermore glass fibers were characterized for reference purposes. With the SFPT the interfacial shear strength (IFFS) and the critical fiber length (lc) as well as the consumed energy of a fiber pull-out and a fiber rupture were determined. In a following step the resulting values of lc were related to the ...

Blending CA with PBS to increase the bonding strength in two-component injection molding
(Society of Plastics Engineers, 2019)
Since CA shows no adhesive properties in the two-component injection molding process with bio based TPU, blends of CA and PBS were produced to decrease the interfacial tension between the materials. While the interfacial tension was calculated from the results of a drop shape analysis, the adhesion strength was measured in peel tests according to the guideline VDI 2019. The comparison of the results gave information about whether the drop shape analysis is a valid method to analyze the adhesive characteristics of ...

Natural fiber reinforced technical (bio-) composites modified with halogen-free flame retardants
(Society of Plastics Engineers, 2019)
Under the aspect of sustainability and the use of alternative materials, engineering thermoplastics such as polybutylene terephthalate (PBT) will be reinforced with renewable raw materials such as regenerated cellulose fibers.
The University of Kassel is developing cellulose regenerated fiber reinforced technical thermoplastics in a state-funded project with further companies. Since pure natural fibers cannot withstand the high operating temperature of engineering thermoplastics (Ts>230°C), regenerated cellulose ...

UV light irradiation of fibers in thermoplastic pultrusion for higher surface energy
(Society of Plastics Engineers, 2018)
Pultrusion is a common way to produce thermoplastic composites reinforced with different kinds of fibers. There are many different opportunities to improve the properties of a thermoplastic material. Different kind of fibers where pultruded in combination with different thermoplastic materials. The fiber content was set to 30wt% comparing the roving strain with the pultruded strain. UV-C light was used in the process to improve the fiber matrix adhesion. The pultruded strain was granulated and injection molded to ...
