Utilitarian and Hedonic Shopping Behavior in the Face of Natural Disaster

Terror management theory suggests that events which make one’s mortality salient also lead to compensatory processes and behaviors meant to alleviate existential anxiety. Applications within the field of consumer behavior have led to the proposal that any such event may also impact materialism and consumption decisions as a protectant from such anxiety. With this in mind, the current study sets out to investigate the personal experiences and subsequent shopping behavior of those impacted by Hurricane Matthew in the coastal southeastern region of the United States. While Hurricane Matthew had nowhere near the destructive impact of Katrina within the continental United States, as the most powerful Atlantic tropical storm in nearly a decade, Hurricane Matthew caused widespread disruptions to services and difficulties for consumers over a very large area, to include Florida, Georgia and the Carolinas. A survey (n = 268) was administered in this region within two weeks from the time the hurricane subsided, regarding both utilitarian (preparation) shopping and hedonic (enjoyment/stress-reduction) shopping activity, both at times directly before and directly after the hurricane. Several scales such as fear during the storm, general tendency for risk aversion, and present temporal presentation were also administered to investigate the relationships between individual differences and their influences on consumer’s perception about the impact of natural disaster on consumers. Results reveal that respondents in our sample engaged in significantly more utilitarian shopping than hedonic shopping both before and after the hurricane. However, initial findings reveal that groups with higher levels of fear during the storm, general tendency for risk aversion, and those with present temporal presentations were more likely to report feeling that they must purchase more ‘of everything’ during the storm, delay purchase of unnecessary/luxury goods, and show concern about crowded shopping areas and becoming a more conscious shopper than low-fear participants

The Perils of Using Self-Deprecating Humor: Customer Evaluations of the Firm after a Service Failure

The current study investigates the firm’s potential use of self-deprecating humor in response to a service failure and examines resulting consumer evaluations. This study utilizes two scenario-based experiments conducted in the contexts of online retailing and restaurant service. The findings indicate that self-deprecating humor leads to customers’ negative evaluations of the company by decreasing forgiveness intentions toward the company. The mechanism which explains low forgiveness intentions is found to involve heightened perception of dishonesty. Moreover, when perceived benignness of the failure is low (vs. high), self-deprecating humor has a stronger adverse effect on perceived dishonesty. This study suggests that firms need to be mindful of the negative consequence of using self-deprecating humor if they are to implement it as a tool for service recovery

The effects of harm directions and service recovery strategies on customer forgiveness and negative word-of-mouth intentions

This study aims to investigate the direction of harm and the role of service recovery strategies on customer positive (i.e., forgiveness) and negative (i.e., word-of-mouth) intentions. We found that customer intentions are stronger among those who are directly affected by the service failure than indirectly affected customers. Further, we assess the role of service recovery in customer intentions after the service failure. The study findings contribute to the development of theory on the “other customers” effect by comparing the consequences of service failure directed at the focal customer and other customers and provide solutions to practitioners to reduce this damaging effect

Hypergraph Motifs and Their Extensions Beyond Binary

Hypergraphs naturally represent group interactions, which are omnipresent in many domains: collaborations of researchers, co-purchases of items, and joint interactions of proteins, to name a few. In this work, we propose tools for answering the following questions: (Q1) what are the structural design principles of real-world hypergraphs? (Q2) how can we compare local structures of hypergraphs of different sizes? (Q3) how can we identify domains from which hypergraphs are? We first define hypergraph motifs (h-motifs), which describe the overlapping patterns of three connected hyperedges. Then, we define the significance of each h-motif in a hypergraph as its occurrences relative to those in properly randomized hypergraphs. Lastly, we define the characteristic profile (CP) as the vector of the normalized significance of every h-motif. Regarding Q1, we find that h-motifs' occurrences in 11 real-world hypergraphs from 5 domains are clearly distinguished from those of randomized hypergraphs. Then, we demonstrate that CPs capture local structural patterns unique to each domain, and thus comparing CPs of hypergraphs addresses Q2 and Q3. The concept of CP is extended to represent the connectivity pattern of each node or hyperedge as a vector, which proves useful in node classification and hyperedge prediction. Our algorithmic contribution is to propose MoCHy, a family of parallel algorithms for counting h-motifs' occurrences in a hypergraph. We theoretically analyze their speed and accuracy and show empirically that the advanced approximate version MoCHy-A+ is more accurate and faster than the basic approximate and exact versions, respectively. Furthermore, we explore ternary hypergraph motifs that extends h-motifs by taking into account not only the presence but also the cardinality of intersections among hyperedges. This extension proves beneficial for all previously mentioned applications.Comment: Extended version of VLDB 2020 paper arXiv:2003.0185

Assembly of different length of polyubiquitins on the catalytic cysteine of E2 enzymes without E3 ligase; a novel application of non-reduced/reduced 2-dimensional electrophoresis

AbstractIn this study using non-reduced/reduced 2-dimensional electrophoresis (NR/R-2DE), we clearly demonstrated that E3-independent ubiquitination by Ube2K produced not only unanchored but also Ube2K-linked polyubiquitins through thioester and isopeptide bonds. E3-independent assembly of polyubiquitins on the catalytic cysteine of Ube2K strongly supports the possibility of ‘en bloc transfer’ for polyubiquitination. From the same analyses of E3-independent ubiquitination products by other E2s, we also found that different lengths of polyubiquitins were linked to different E2s through thioester bond; longer chains by Cdc34 like Ube2K, short chains by Ube2g2, and mono-ubiquitin by UbcH10. Our results suggest that E2s possess the different intrinsic catalytic activities for polyubiquitination

Changes in the Outdoor Wear Market: Focused on the South Korean Market

People have become interested in wellness and health, which has led to well-being trends and increased participation in activities. Therefore, the outdoor wear market has shown growth for several years. However, the outdoor wear market of South Korea is becoming saturated. Moreover, Outdoor wear consumers are tired of same design products. The sportswear companies are trying to develop athleisure products. Therefore, it is time to develop outdoor products for emotional approach. According to results, when consumers purchase outdoor wear, they consider the functionality of the materials more than they do when purchasing ordinary clothes. Outdoor wear consumers\u27 pursued images were classified into three types: urban, minimalist, and active. Outdoor wear selection criteria were classified into two types: instrumental function and expressive function. Outdoor wear brands need to qualify their products functionally and meet their segmented consumers\u27 demands by developing products depending on their image from the planning stage

Brand trust and avoidance following brand crisis : a quasi-experiment on the effect of franchisor statements

Although franchising has become an important growth strategy in severalindustries over the last few decades, there are few empirical studies about the effects of franchisor communication strategy on customer responses in the context of franchise brand crisis. Two quasi-experimental studies were conducted to test the effect ofa franchisor ownership separation statement on brand trust and brand avoidance following a brand crisis situation. Results show that a franchisor’s explicit communication of the franchise brand’s individual ownership business structure is useful in preventing further negative spillover effect throughout the franchised chain when thebrand crisis occurs at a single franchise location. The authors also investigate the mechanism through which such communication influences customer behavior and the moderating effect of the brand crisis severity in affecting brand evaluation. These results offer guidance to franchise brand managers by providing insight into how to overcome a franchise brand crisis and by suggesting franchise context-specific managerial recommendation

Burden of Human papillomavirus (HPV)-related disease and potential impact of HPV vaccines in the Republic of Korea

Background: We aimed to review the burden and the potential impact of human papillomavirus (HPV) vaccines on HPV-related diseases in the Republic of Korea and to discuss cervical cancer prevention practices in this country. Methods: Cancer burden statistics were retrieved from GLOBOCAN-2018 and Statistics Korea. HPV disease burden was assessed via systematic review. Vaccine types relative contribution (RC) was estimated using data from an international project using formalin-fixed paraffin-embedded specimens. Results: Despite a downtrend in cervical cancer in recent years, Korean rates remain high. In contrast, oropharyngeal cancer incidence has gradually increased and other anogenital cancers remain rare. In Korea, HPV prevalence in general population is around 20%. In cervical cancer, RC of HPVs 16/18 (74.0%) increased to 92.0% when including HPVs 31/33/45/52/58. Limited information was available for other HPV-related cancer sites. Regarding prevention, since the inclusion of the HPV vaccine into the National Immunization Program, almost half (49%) of the target cohort in 2016 had received the first dose of vaccine. Further, percentage of women screened with pap has increased from 41.1%-2009 to 53.0%-2016. Conclusions: HPV-related disease burden in Korea is significant. Results suggest that the combination of effective and high coverage HPV vaccination and screening programmes could substantially impact on HPV-related disease in Korea

Identification of dendritic cell precursor from the CD11c+ cells expressing high levels of MHC class II molecules in the culture of bone marrow with FLT3 ligand

Dendritic cells (DCs) are readily generated from the culture of mouse bone marrow (BM) treated with either granulocyte macrophage-colony stimulating factor (GM-CSF) or FMS-like tyrosine kinase 3 ligand (FLT3L). CD11c+MHCII+ or CD11c+MHCIIhi cells are routinely isolated from those BM cultures and generally used as in vitro-generated DCs for a variety of experiments and therapies. Here, we examined CD11c+ cells in the BM culture with GM-CSF or FLT3L by staining with a monoclonal antibody 2A1 that is known to recognize mature or activated DCs. Most of the cells within the CD11c+MHCIIhi DC gate were 2A1+ in the BM culture with GM-CSF (GM-BM culture). In the BM culture with FLT3L (FL-BM culture), almost of all the CD11c+MHCIIhi cells were within the classical DC2 (cDC2) gate. The analysis of FL-BM culture revealed that a majority of cDC2-gated CD11c+MHCIIhi cells exhibited a 2A1-CD83-CD115+CX3CR1+ phenotype, and the others consisted of 2A1+CD83+CD115-CX3CR1- and 2A1-CD83-CD115-CX3CR1- cells. According to the antigen uptake and presentation, morphologies, and gene expression profiles, 2A1-CD83-CD115-CX3CR1- cells were immature cDC2s and 2A1+CD83+CD115-CX3CR1- cells were mature cDC2s. Unexpectedly, however, 2A1-CD83-CD115+CX3CR1+ cells, the most abundant cDC2-gated MHCIIhi cell subset in FL-BM culture, were non-DCs. Adoptive cell transfer experiments in the FL-BM culture confirmed that the cDC2-gated MHCIIhi non-DCs were precursors to cDC2s, i.e., MHCIIhi pre-cDC2s. MHCIIhi pre-cDC2s also expressed the higher level of DC-specific transcription factor Zbtb46 as similarly as immature cDC2s. Besides, MHCIIhi pre-cDC2s were generated only from pre-cDCs and common DC progenitor (CDP) cells but not from monocytes and common monocyte progenitor (cMoP) cells, verifying that MHCIIhi pre-cDC2s are close lineage to cDCs. All in all, our study identified and characterized a new cDC precursor, exhibiting a CD11c+MHCIIhiCD115+CX3CR1+ phenotype, in FL-BM culture

Original Article

99 cases were operated while we could not use antibiotics. The author traced X-ray photos on paper and measured areas of the peeled cavities with a planimeter. Results were as follows. 1) 66 cases had increasing stage and the rates were more than 30 %. 2) Cases with good developments showed larger original areas (50〜100cm^2) and smaller increasing rates (less than 30 %). 3) Also their X-ray photos showed coinciding or almost coinciding lines of the apices of lungs and the bases of cavities, but we had to take precautions against suppuration when they showed a horizontal line several days after operation. 4) Most of too high degree of adhesion or thickning of pleura did not show good results. When we found a cord which we must manage with some procedures by pneumolysis we must attend to suppuration too. 5)We ought to resect 4th or 5th rib more than 20 cm and 5th or 4th several cm supplementary. 6) As a method of constriction we commend the INVAGI.NATION method. 7) The author noticed in a considerable number of cases that the areas of cavities increased again after they kept long balanced stages
