Direct Digital Manufacturing

Direct digital manufacturing (DDM), is advancing rapidly in capability and commercial potential. Directly from CAD data, parts are manufactured without traditional cutting, forming or casting methods. Some of the main developments of the recent past in DDM are discussed in this article. Microstructural and property data will be presented for each type of process, illustrating the benefits and limitations of direct digital manufacturing on various materials, and focusing on emerging and projected applications of metal and ceramic materials by direct digital manufacturing. The review is based on an extensive literature review covering academic publications, company documents and web site information.

Buying Behaviour

In the last years, research investigating consumer behaviour and how their decision-making process has advanced and has become an important topic in the marketing society and literature. To advance the research further, this paper presents an extensive literature review of academic publications in the area of buying decision-making process in marketing and its status. Furthermore, the paper presents latest trends and themes that emerge there. Based on 24 journal articles, reports and marketing books, the core models and theories in this area were evaluated and discussed. Moreover, a framework of “moments that matter” in consumer decision-making process and factors that influence them was elaborated for a possibility to influence consumer behaviour in favour of company’s offers. Furthermore, recommendations for marketers were suggested for deeper understanding the consumer behaviour and their buying strategies to empower marketing campaigns and be a success in the market. The paper also suggests several directions for future research related to buying behaviour.

O estudo se desenvolveu por meio da fabricação e posterior ensaio de corpos de prova confeccionados por meio de Direct Digital Manufacturing (DDM), usinagem de placas extrudadas e injeção de polímeros. Um comparativo das propriedades mecânicas obtidas pelos ensaios de tração foi realizada. A avaliação das aplicações de peças DDM, especialmente por se tratar de uma tecnologia relativamente jovem e que ainda não tem todo seu potencial explorado, foi o que motivou a realização desse trabalho. Cada um dos três processos avaliados apresentou particularidades. Os ensaios de peças usinadas e injetadas apresentaram resultados bem característicos, sendo o material usinado mais resistivo à forças trativas do que o material injetado. As peças fabricadas por DDM se mostraram tão eficientes quanto à injeção no ensaio de tração.

Purpose – In order to continue to respond to patron needs in a relevant way, it is necessary to continuously reevaluate the central message that the library website is intended to convey. It ' s necessary to question assumptions, listen to user needs, and shift our paradigm to make the library web presence as effective as possible. Design/methodology/approach – This is a regular viewpoint column. A basic literature review was done prior to the column being written. Findings – The library Web site remains, in many respects, the “first face” of the library for patrons. To remain relevant, traditional methodologies used in library science may need to be set aside or catered to the needs of the patron. Originality/value – Various methods regarding design philosophy are explored which may be of use to information professionals responsible for the design and content of the library Web sites.

Research Questions

Although the number of countries that have adopted e-voting has decreased lately, the number of academic publications on e-voting adoption has increased in the last two years. To date, there is no coherent narrative in the existing literature that explains the progress of the research on e-voting adoption. This article aims to answer the following research question: “How has research on the topic of e-voting adoption progressed over the last 15 years?” The article provides a semi-systematic review of 78 studies that were conducted from 2005 to 2020. In this article, I argue that although the studies on e-voting adoption are dominated by a single case study, by research in the United States, and by the positivist paradigm, scholars have employed the term “e-voting adoption” diversely and the research on e-voting adoption has evolved to address more specific research questions. Recommendations for the future agenda of research on e-voting adoption are also discussed.

Cognitive Legitimacy

Customer cognitive legitimacy is an important factor in a new business venture’s survival. Based on an extensive literature review of customer cognitive legitimacy, this book examines the consistent conceptualisation of the concept and its dimensional structure. This consistent conceptualisation facilitates the development of the reliable and valid three-dimensional customer cognitive legitimacy scale in 10 studies. The scale is based on potential customers’ interest in acquiring knowledge about a product and the company responsible for it, their perception of the company’s and the product’s future, and their perception of how competent the company’s managers are.

Background. Pseudomyxoma peritonei (PMP) is a rare neoplasm involving the peritoneum. Most PMPs are low-grade appendicular mucinous neoplasms (LAMNs). There have been no reports of PMP originating from a transverse colonic mucinous adenocarcinoma and causing metastatic mucinous adenocarcinoma. Case Presentation. We report a 46-year-old woman who presented with a right abdominal mass of more than 4-month duration. Transverse colonic mucinous adenocarcinoma, PMP, and ovarian metastatic mucinous adenocarcinoma were diagnosed. The patient’s diet was normal, and she had no abdominal pain or bloating. The abdomen mass increased in the month before treatment. After chemotherapy, the transverse colon mass and ovarian giant cyst were resected and about 2000 mL of gelatinous tumor tissue was removed. Postoperative histology confirmed PMP from the transverse colonic mucinous adenocarcinoma, ovarian metastatic mucinous adenocarcinoma, and mesocolon metastatic cancer. Multiple lung metastases appeared 8 months after surgery. The patient died 29 months after surgery because of an inability to eat and poor nutrition. A systematic literature review of the management and outcome of all known similar cases is also presented. Conclusions. This is the first report of PMP originating from a transverse colonic mucinous adenocarcinoma. It was diagnosed during resective surgery, involved ovarian metastasis, and survival was short. We did an extensive literature review in order to describe the clinical characteristics, histopathological findings, genetic profile, and potential treatments of PMP caused by nonappendiceal mucinous adenocarcinoma.
