Title redacted: the impact of negative online review censorship

Purpose Consumers are increasingly using review sites to exchange product information, whereas companies attempt to maintain control of brand-related communications. One method marketers may take to retain control is to remove negative opinions about the brand. This paper aims to examine the impact on consumer’s brand perceptions when negative reviews are censored. Design/methodology/approach Two experimental studies were conducted to assess whether censorship of a negative online review, in the form of removal by the company, weakens brand relationship quality (BRQ) dimensions. Findings The results show that censoring negative online reviews has a damaging effect on BRQ. Additionally, the findings indicate that a brand may not be able to increase BRQ when a negative review has been posted, however strategic measures can be taken to diminish the potentially harmful impact. Originality/value As many brands still do not adequately understand how to handle negative online reviews, this research offers valuable implications in furthering the examination of negative electronic word-of-mouth and ways to diminish its harmful effects. Additionally, while substantial research focuses on the positive consequences of brand relationships, this research answers calls to examine the negative impacts to BRQ.

ANALYSIS OF THE IMPACT OF SOCIAL NETWORKS ON CUSTOMERS’ DECISION TO BUY ONLINE: RESEARCH CONCEPT

The article discusses in detail the theoretical foundations of the development of Internet commerce and the factors influencing the decision to buy online from the point of view of the concept of Web 2.0. The authors have developed and substantiated the concept of marketing research aimed at studying the factors of social networks in making a purchase decision. In this case, the independent variables are factors such as customer support, information exchange, product rating, the dependent variable in the developed study is customer intention to purchase. To test the hypotheses formulated in the article, it is proposed to conduct a survey with a detailed study and justification of the factors that influence online purchases. This topic is undoubtedly relevant in modern market conditions.

Development of E-Business towards Labor Market for Higher Education

The internet business is used for information exchange, product catalogs, promotional media, e-mails, bulletin boards, electronic questionnaires, and mailing lists. The internet can also be used to dialogue, discuss, and consult with consumers online, so that consumers can be involved proactively and interactively in the design, development, marketing, and sale of products. By using the internet, we can run an electronic business or commonly called e-business as a means of expanding employment opportunities. Given the smaller quota to find employment, that ebusiness is the right solution for college graduates.

The sequences near Chi sites allow the RecBCD pathway to avoid genomic rearrangements

Bacterial recombinational repair is initiated by RecBCD, which creates a 3′ single-stranded DNA (ssDNA) tail on each side of a double strand break (DSB). Each tail terminates in a Chi site sequence that is usually distant from the break. Once an ssDNA-RecA filament forms on a tail, the tail searches for homologous double-stranded DNA (dsDNA) to use as template for DSB repair. Here we show that the nucleoprotein filaments rarely trigger sufficient synthesis to form an irreversible repair unless a long strand exchange product forms at the 3′ end of the filament. Our experimental data and modeling suggest that terminating both filaments with Chi sites allows recombinational repair to strongly suppress fatal genomic rearrangements resulting from mistakenly joining different copies of a repeated sequence after a DSB has occurred within a repeat. Taken together our evidence highlights cellular safe fail mechanisms that bacteria use to avoid potentially lethal situations.

Lactide polymerization with iron alkoxide complexes

This report presents the results of a study on the preparation of iron alkoxide complexes chelated by diiminopyridine ligands and their role in the room temperature polymerization of rac-lactide. Reaction of N,N′-(p-R-C6H4CH2)2-diiminopyridines (R = H (1), F (2)) with FeX2 (X = Cl, Br) yielded the homoleptic complexes [(1)2Fe][FeX4] or [(2)2Fe][FeX4], respectively. Treating the latter with Na[BPh4] afforded the anion exchange product [(2)2Fe][BPh4]2, which was characterized by 1H NMR and absorption spectroscopy, combustion analysis, and single crystal X-ray diffraction. Various attempts to grow crystals of [(1)2Fe][FeX4] and [(2)2Fe][FeX4] culminated in the isolation of single crystals of [(2)2Fe][Cl6Fe2O] that was characterized by X-ray diffraction. Attempted synthesis of well-defined, mononuclear alkoxide derivatives from [(1)2Fe]2+ or [(2)2Fe]2+ gave mostly intractable products, but in one case we obtained the crystallographically characterized sodium iron cluster Na4Fe2(OC6H4F)8(THF)2. An aryloxide derivative proved accessible by reaction of NaOC6H4F with the mono-ligand precursor LFeCl2 (L = N,N′-dimesityl-diiminopyridine), but characterization of LFe(OC6H4F)2 was limited to a single crystal X-ray diffraction analysis, owing to unsuccessful attempts at isolating pure samples. The difficulties encountered in the isolation of pure alkoxide derivatives prompted us to use in-situ generated LFe(OEt)2 for studying the polymerization of rac-lactide. This system was found to be moderately active at room temperature and with a slight preference for the formation of a heterotactic polymer (Pr = 0.54–0.65). Large polydispersities of 1.5–2.0 indicated the presence of transesterification side-reactions, which were confirmed by the presence of peaks with m/z = n 144 + M(EtOH) + M(Na+) and m/z = (n + 0.5) 144 + M(EtOH) + M(Na+) in MALDI-MS.

A Model of the Geometric Tolerances Modeling and Representation Process

Fundamental to the IMP, is the requirement to provide a harmonized data model and represent it appropriately, including geometric tolerances information that can be understood well by computers and users. In this paper, we propose a layered conformance level geometric tolerances representation model. This model uses the widely applied ASME Y14.5M-1994 as its foundation layer by abstracting most information from this standard. Thus, different application domains in an enterprise can use this data model to exchange product information. This model is further transformed with XML Schema that can be used to generate XML instance file to satisfy geometric tolerances representation requirements in IMP.

OXIDATION MECHANISM OF THE BUTADIYNYL RADICAL, C4H: ANALOGUE OF C2H OR NOT?

Reactions of the carbon-chain radicals are of great importance in the combustion and astrophysical processes. The kinetics of the butadiynyl radical, C 4 H , has received recent attention. While there has been sufficient knowledge concerning the oxidation of the ethynyl radical, C 2 H , oxidation of the higher even-numbered members C 2n H (n > 1) is hardly known. In this paper, to enrich the C 4 H -chemistry, we report the first study of the oxidation mechanism of C 4 H . At the CCSD(T)/aug-cc-pVTZ//B3LYP/6-311++G(d,p)+ZPVE level, the potential energy surface (PES) survey is presented covering various product channels P1( CO + HC 3 O ) (-152.7 kcal/mol), P2( C 3 H + CO 2) (-117.9), P3( HCO + C 3 O ) (-108.5), P4( HC 4 O +3 O ) (-45.2), and P5( OH + C 4 O ) (-33.2) accompanied by the master equation rate constant calculations. Despite the similarity in the PES, the kinetics of C 4 H +3 O 2 differs dramatically from that of the analogous C 2 H +3 O 2 reaction. For the C 4 H +3 O 2 reaction, the O -abstraction product P4( HC 4 O +3 O ) is almost the exclusive product, whereas the lowest C , O -exchange product P1( CO + HC 3 O ) and other products have little importance. By contrast, the C 2 H +3 O 2 reaction favors the C , O -exchange product HCO + CO . Being overall barrierless and mainly associated with the molecular → atomic oxygen conversion, the C 4 H +3 O 2 reaction should play an important role in the soot formation and interstellar chemistry where C 4 H is involved.

Global Dynamics Analysis of Homogeneous New Products Diffusion Model

A mathematical model with stage structures is presented that incorporates the awareness stage and the decision-making stage; individuals exchange product information by two channels: mass media and interpersonal communication. When the persuasive advertisement is neglected in the decision-making stage, we find a threshold value about whether new products diffusion is successful or not. When the persuasive advertisement is considered, there must exist a positive equilibrium under some parameter condition; moreover, it must be globally asymptotically stable as long as it exists. Results show that the persuasive advertisement in the decision-making stage does not influence new products' successful diffusion, but the critical value that new products diffuse successfully decreases when the persuasive advertisement is considered. Some numerical simulations confirm our theoretical analysis and demonstrate the influence of parameters on the system. Corresponding to the analysis results, some diffusion strategies are provided.
