Purpose - People have long thought that disorderly space would influence their lives negatively. However, disorderly space may have positive impact such as increasing sales for new products for store managers. Borrowing the prior findings that disorderly space enhances creativity, we developed two hypotheses regarding space order, product newness, and new product adoption. We hypothesize that space order negatively influences new product adoption and that the proposed negative effect of space order on new product adoption is moderated by product newness. Research design, data, and methodology - We conducted a pre-test in China using 70 undergraduate students to test whether two newly developed cosmetic products were appropriate for the experimental stimuli. We confirmed that a fragrance patch concept, which is unavailable in the market, is a RNP (Really New Product), and an edible fragrance, which is available in the market, is an INP (Incrementally New Product). Next, we conducted a main experiment with a 2 (Space order: orderly vs. disorderly) × 2 (Product newness: RNP vs. INP) between-subjects design in China using 100 undergraduate students. Half of the participants answered questions on the disorderly desk and the other half answered questions on the orderly desk. Results - We obtained evidence from the main experiment that consumers' new product adoption is the function of space order and product newness. First, participants were more likely to adopt the RNP when they were in the disorderly space than in the orderly space. However, the effect of space order on new product adoption disappeared when the product was INP; the adoption rates for the INP did not differ between the participants who answered questions on the disorderly desk and the participants who did so on the orderly desk. Conclusions - Our findings are counter intuitive. Contrary to the conventional wisdom that neat and tidy space benefits store managers, the research demonstrated that disorderly space increases sales, providing fresh insights into store managers to manage their stores and shops to sell new products. In order to help store visitors understand the value of really new products, store managers will have to sacrifice space order to some extent.

In manufacturing companies, engineering information is a central data which defines a product to be produced. This is changed by various factors such as changes of product configuration, changes of drawings information of a technology's licensor, etc, and these changes essentially accompany the changes of a product BOM (Bill of Materials) structure. Thus, engineering changes gives a heavy burden to information management within enterprise because the changes of product BOM have an influence on each departmental BOM such as a procurement BOM, a manufacturing BOM, a quotation BOM, etc. Especially, these changes of product BOM due to the engineering changes is inevitably and frequently happened by a customer's requirements in a customer-oriented make-to-order manufacturing environments. In these manufacturing environments, information gap among each department from the first contact point of customer to engineering, materials, production, quality, and management is very close, and thus it is very important that the change information of product BOM due to changes of product specification and engineering information are efficiently communicated among each department. This paper describes a procedure of determining product specification and of generating product BOM, and proposes an efficient management scheme for the change process of product BOM information due to changes of product specification and engineering. Also, to show the effectiveness of the proposed product BOM management scheme, a product BOM management system is implemented for the ship engine division of 'H' company, one of customer-oriented make-to-order manufacturing enterprises.

This study employed high performance liquid chromatography (HPLC) coupled to an on-line $ABTS^+$ radical scavenging detection (RSD) system along with HPLC-electro spin impact/mass spectrometry (ESI/MS), to rapidly determine and identify antioxidant compounds occurring in blueberry extract. The extract was separated by HPLC, and then the radical scavenging activities of the separated compounds were evaluated by the on-line coupled $ABTS^+$-RSD system. The negative peaks of the $ABTS^+$-RSD system, which indicates the presence of antioxidant activity, were monitored by measuring the decrease in absorbance at 734 nm. The active components in the blueberry extract were identified by HPLC-ESI/MS using their MS spectra and retention times. According to the data acquired from the on-line HPLC-$ABTS^+$-based assay and HPLC-ESI/MS systems, the antioxidant compounds detected in the blueberry extract were identified as chlorogenic acid and 11 anthocyanins.

A product family design has received much attention over the last several decades, since a product family-based development shortens lead-times and reduces cost, as well as increases efficiency and effectiveness of the product realization process. It is challenging work, however, to define the product family design in the heterogeneous product development environments, due to myriads of products related information described in different ways across products in any companies. In this paper, we provided a way of defining product family design framework using formal concept analysis and ontology language. Based on this, the specific product family can be derived by ontological reasoning, and the new product concept can be also expanded in the framework. The proposed framework is formalized using OWL (Web Ontology Language) and implemented in $Prot{\acute{e}}g{\acute{e}}$. Actual product family design algorithm is carried out using FaCT++ engine, a plug-in to $Prot{\acute{e}}g{\acute{e}}$, and the benefits of the proposed method are also demonstrated through a case study.

The internet has become an important part of the many aspects of people's daily lives such as work, study, entertainment and in form of electronic commerce, shopping. Electronic commerce is growing rapidly in Kenya. There are many successful business-to-business, business-to-customer and customer-to-customer online shopping companies in Kenya. As a consequence, competition between vendors is intense and, therefore, mitigating the negative effects of high product uncertainty is necessary requirement as it remains a biggest hindrance for success of the online shopping. The purpose of this research is to investigate how online product description, third party product assurance, customer service and website design mitigate the negative impact of high product uncertainty. A questionnaire with 28 items is designed to collect data from online customers. Using multiple regression analysis, the relationship between dependent variable (product uncertainty) and independent variables such as product description, third party assurance, website design and customer service is tested. The result shows that all the independent variables are negatively correlated with dependent variable, which means that product description, third party assurance, website design and customer service can be used by online vendors to lessen the problem of product uncertainty in online markets.
