MANAGING MARKETING COMPETENCIES: A framework for understanding antecedents of marketing capability and its relation to the company’s core competencies

Core competencies are the crown jewels of a company and, therefore, should be carefully identified, nurtured and developed. Based on the resource-based theory, this study explores how core competence can lead to firms’ competitive advantage, and how a marketing firm can identify its core competence in the sector to attain competitive advantage

The market reaction to unexpected earnings via discretionary accruals and sustainability reporting

We investigate the impact of earnings management on the sustainability reporting and branding position among the listed companies in the UK. We pay particular attention to the roles of discretionary accruals and find that they are negatively related to future stock returns. Key points This study builds on this prior work regarding the contribution of accruals to explaining future returns To understand the association between returns and earnings in accounting. Attempts to investigate the relationship by linking earnings management in annual financial and sustainability reporting A considerable body of research is concerned with the relation between accounting stock returns and earnings. To find positive or negative earnings management can create positive or negative returns. Managers may try to manage their earnings by using discretionary accruals. To show the ability of accruals for both actual and simulated earnings management

Extra virgin olive oil in maternal diet increases osteogenic genes expression, but high amounts have deleterious effects on bones in mice offspring at adolescence

Objective(s): Maternal high-fat diet has been shown to have deleterious effects on the offspring bones. However, there is no study to assess the effects of type and amount of maternal dietary oil in an isocaloric diet, with focus on extra virgin olive oil (EVOO). The objective of the current study was to test the hypothesis that type of maternal dietary oil has more effects than its amount in an isocaloric diet during gestation and lactation on bone genes expression in offspring in adolescence. Materials and Methods: Virgin female C57BL/6 mice were impregnated and fed either the AIN 93G diet (received 16% of calories as soybean oil, as a control diet, or EVOO) or a high fat AIN 93G diet (received 45% of calories as soybean oil or EVOO) from the time of vaginal plug confirmation until offspring’s weaning. Results: After adjusting for the amount of oils, osteoprotegerin/ receptor activator of nuclear factor NF-κB ligand (OPG/RANK-L) and OPG expressions were 6.1- and 2.8-folds higher in offspring born to EVOO compared with soybean oil-fed mothers. OPG, beta-catenin, and OPG/RANK-L expression were 88%, 94%, and 70% lower in offspring born to the 45% oil-fed mothers compared with the 16% group. In contrast, peroxisome proliferator-activated receptor gamma-2 (PPARγ2) gene expression was higher in the 45% oil group, adjusted for the types of oil. Conclusion: Maternal EVOO consumption, but not soybean oil increased osteoblastic gene expression, and high amounts of both oils decreased osteoblastic and increased adipogenic genes expression in adolescent offspring

INTO THE UNKNOWN: Impact of Coronavirus on UK hotel stock performance

As the Coronavirus disease (COVID-19) spread in March 2020, it crashed economies across the world, including in the UK. This study investigates the impact of the COVID-19 pandemic outbreak on the stock return of publicly listed hotels in the UK. By employing the event-study approach, this study (i) scrutinizes the effect of the Coronavirus pandemic on UK hotel stock price changes, (ii) examines how the magnitude of the COVID-19 outbreak has affected stock price movements in the UK market place, and (iii) examines how COVID-19 has impacted the hotel industry via the reactions of the stock market. Our results show that listed hotels in the stock market experienced substantial negative cumulative abnormal returns. This article’s findings could be useful for businesses to be better prepared for similar future pandemics

Promoter Hypermethylation of Estrogen Receptor Alpha Gene Is Correlated to Estrogen Receptor Negativity in Iranian Patients with Sporadic Breast Cancer

Objective: Breast Cancer is the most common cancer in Iranian women. Breast tumors are classified based on the estrogen receptor alpha (ERα) expression status into ER negative and ER positive tumors. ER negative tumors tend to have worse prognosis and less likely to respond to endocrine therapy. Aberrant methylation of gene promoter is one of the mechanisms for gene silencing in breast tumors. Because of its reversible nature, promoter methylation is a good target for new therapeutic strategies. We aimed to evaluate the frequency of this epigenetic event in ERα gene and its association to clinicopathological features in Iranian breast cancer patients.Materials and Methods: In this case control study the patient series consisted of 100 sporadic primary breast cancer cases (51 ER negative and 49 ER positive tumors). None of the participants had chemo or radiotherapy before surgery. In breast tumors ERα promoter methylation were assessed with methylation specific polymerase chain reaction (MSP). Data was collected on clinicopathological features of the patients. Correlation between ERα methylation and clinicopathological characteristics of the patients was investigated by Pearson Chi-Square and Fisher’s exact test.Results: ERα methylation was detected in 98% of ER negative and 65% of ER positive breast tumors. A strong correlation was found between ERα methylation and ER negativity in tumors (p<0.0001). Also, ERα methylation has associated to progesterone receptor negativity (p<0.008) and double receptor negative status (p<0.0001) in breast tumors.Conclusion: ERα methylation occurs with high frequency in the breast tumors of Iranian breast cancer patients and may play a considerable role in pathogenesis of ERα negative tumors as a poor prognosis and more aggressive category. The reversible nature of DNA methylation may provide new therapeutic possibilities in ER negative breast tumors

TMPRSS2 polymorphism (rs12329760) and the severity of the COVID-19 in Iranian population.

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has been responsible for the recent pandemic since early 2020. Due to the wide range of clinical symptoms of this disease, from asymptomatic to severe and critical forms, it seems that genetic differences among patients, along with other factors (such as gender, age, and underlying diseases), can explain part of the variation in disease symptoms. The TMPRSS2 enzyme plays a vital role in the early stages of the interaction of the SARS-CoV-2 with the host cells by facilitating viral entry. There is a polymorphism in the TMPRSS2 gene, called rs12329760(C to T) as a missense variant, which causes the replacement of valine to methionine in the TMPRSS2 protein at position 160. The present study investigated the association between the TMPRSS2 genotype and the severity of the Coronavirus disease 2019 (COVID-19) in Iranian patients. The TMPRSS2 genotype of 251 COVID-19 patients (151 patients with asymptomatic to mild and 100 patients with severe to critical symptoms) was detected on genomic DNA extracted from patients' peripheral blood via the ARMS-PCR method. Our results showed a significant association between the minor T allele and the severity of the COVID-19 (P-value = 0.043) under the dominant and additive inheritance model. In conclusion, the results of this study showed that the T allele of the rs12329760 in the TMPRSS2 gene is a risk allele for severe form of COVID-19 in Iranian patients in contrast to most previous studies on this variant in European ancestry populations which suggested this variant as a protective allele. Our results reiterate to the ethnic-specific risk alleles and hidden unknown complexity behind the host genetic susceptibility. However, further studies are needed to address the complex mechanisms behind the interaction of the TMPRSS2 protein and the SARS-CoV-2 and the role of rs12329760 polymorphism in determining the disease severity
