Oil Market Factors as a Source of Commonality in Liquidity in International Equity Markets

When stock markets are less liquid or illiquid, investors are expected to require compensation for taking the risk of not being able to sell quickly. Many studies have documented the existence of the co-movements (commonality) of market liquidity in equity markets as a priced factor. The primary objective of this paper is to introduce the oil market as a potential source of commonality in liquidity. We hypothesize that conditions specific to the oil market can contribute to commonality in liquidity affecting both supply-side and demand-side factors because of its importance to the global economy in general. To this aim, a sample of firms is drawn from 50 countries spanning the period from January 1995 to December 2015. We examine two channels that transmit the effect of oil market movements to the liquidity commonality in international equity markets, namely, oil price returns and oil price volatility. Seemingly unrelated regressions (SUR) are utilized to estimate the effect of oil factors on commonality in liquidity. We find that the returns and volatility of oil prices explain the commonality in liquidity in countries with higher integration with oil markets. In addition, we show that the effect of oil volatility is more pronounced for net oil exporters as opposed to net oil importers after controlling for oil sensitivity. These results are robust to controlling for possible sources of commonality in liquidity as found in the literature and alternative estimation specifications.
Ecolabeling as a Policy Instrument for More Sustainable Development: The Evidence of Supply and Demand Interactions from Russia

Ecolabeling can complement more conventional policy instruments such as taxes and subsidies to stimulate more sustainable development of the economy. However, in practice, ecolabels may not always comply with legal requirements in terms of reliability, accuracy and clarity, and sometimes deliberately mislead the consumer. In Russia and many other developing countries, the problem of inaccurate information on the environmental properties of goods and services is still not recognized. The only regulatory document that currently defines the basic principles for developing and using environmental labels and declarations is the national versions of international standards ISO 14020/14021/14024/14025-Environmental Labels Package. This paper contributes to the literature in two main dimensions. It assesses the degree of prevalence of ecolabeling in the Russian market of everyday goods and the reliability and informational content of frequently used labels (supply-side research). Second, it estimates the consumers’ awareness and reaction to ecolabeled products (demand-side research). The most obvious finding to emerge from this study is that low consumer awareness keeps the level of greenwashing low, but at the same time does not stimulate eco-innovations. We suggest developing smartphone applications that allow buyers to check the compliance of ecolabels on a product with ISO standards directly during the shopping process. We propose to use this approach as a cost-effective and straightforward way to simultaneously raise consumer awareness of ecolabeling and reduce the likelihood of greenwashing.
Exemplifying Stratified Deforestation in Four Protected Areas in Madagascar

Protected areas (PAs) are a cornerstone for conservation biodiversity. Madagascar, as a hotspot for biodiversity, has a network of 114 terrestrial protected areas covering the main forest types occurring on the island. Deforestation continues unabated despite the network covering 11% of the island. Here we present a case study approach reporting on four PAs from the humid forests, dry western forests, and southwestern dry and spiny forests and thickets. To describe deforestation in and around the case sites, we have considered a time window of 30 years for analysis, focusing on six years with reliable data: 1990, 2000, 2010, 2015 (the year of latest PA network update), and 2017. We have considered forest versus other land covers within the PAs in “buffers” at a distance of 500 m, 2.5 km, 5 km, and 10 km from the border of the PA. These buffers were set from the border towards the center of the PA (inside the PAs) and from the border outside the PAs. The smallest PAs, Kasijy (IUCN IV), and Behara Tranomaro (no IUCN category), showed the least forest loss. Tsaratanana (IUCN I) had the highest deforestation rates within the last two years of analysis, with deforestation concentrated in the core area. Ranobe PK-32 (no IUCN category), originally with the largest forest extent, has lost most of its forest cover and showed the highest annual deforestation rate (3.5%) between 2015 and 2017. All four cases prove to be very challenging to manage. Future conservation activities require tailored interventions to account for site-specific current and potential future threats, as detailed in this contribution.
Impact of Nitrogen Rate in Conventional and Organic Production Systems on Yield and Bread Baking Quality of Soft Red Winter Wheat

Soft red winter wheat (SRW) is characterized by high yield and relatively low protein content. In Kentucky, there is growing demand from local artisan bread bakers for regionally produced flour, requiring production of grain with increased protein content and/or strength. The objective of this two-year field experiment was to evaluate the effect of nitrogen (N) management on five cultivars of winter wheat on yield and bread baking quality traits of modern and landrace SRW cultivars (Triticum aestivum L.). All five cultivars were evaluated using two N application rates in conventional and organic production systems. All traits measured were significantly affected by the agricultural production system and N rate, although plant height and other quality traits varied by study year. Significantly higher yields were achieved in the conventional system at a relatively low N rate (67.2 kg ha−1) in both study years (2017–2019) (p < 0.01). Results were variable by cultivar and a locally bred, high-yielding cultivar (Pembroke 2014) had the highest lactic acid solvent retention capacity score and thousand kernel weight of the cultivars evaluated. In addition, a landrace cultivar (Purple Straw) had the highest grain N and plant height. A French soft wheat, Soissons, had the highest sedimentation value and Pembroke 2016 achieved the highest yield. The findings from this study suggest the possibility of attaining a desirable grain with quality traits of SRW wheat that meets the needs of local bread wheat production in Kentucky through improving the optimization of cultivar selection, N management and specific considerations for conventional and organic systems.
Sustainability and green practices: the role of stakeholder power in fast-food franchise chains

Purpose This paper aims to explore how the power of salient stakeholders involved in the green waste management of franchise chains can impact the ability of the chains to change their green practices. Design/methodology/approach This qualitative study is based on interview data from 19 franchisors and their head office staff operating in the fast-food sector in France where franchise chains have been ‘named and shamed’ as continuing to ignore waste management regulation. Findings The findings suggest that both the form and bases of power of different stakeholder groups have important implications for the implementation of green practices, even those required by law. The authors find that the franchisees’ central network position alters the ability of franchisors to directly engage in dialog, consult with, and educate key stakeholders, creating additional challenges for franchisors in the implementation process. Research limitations/implications The qualitative nature of the study limits the extent to which the findings can be generalized. Future studies could develop an instrument to assess franchisor perceptions of stakeholder power. Practical implications The findings suggest that franchisors should consider carefully how they communicate changes to green practices to their franchisees to ensure not only their compliance but also their motivation to engage with those stakeholders with whom they have regular interactions. The findings can also help governments to better understand how to involve other stakeholders to ensure effective environmental legislation. Originality/value The study is the first, to the authors’ knowledge, to consider the role of stakeholders in the implementation of green practices in franchise chains. By examining franchise chains, this paper provides new insights into the role of an additional stakeholder, the franchisee, and enriches the literature on green practices in the hospitality sector.
Efficacy and Pharmacological Mechanism of Poria cocos-Based Formulas Combined With Chemotherapy for Ovarian Cancer: A Integrated Systems Pharmacology Study

Previous studies have shown that Poria cocos-based formulas combined with chemotherapy can improve the quality of life of ovarian cancer patients. However, the results are still controversial. We systematically searched the literature from eight databases to evaluate the efficacy and safety of Poria cocos-based formulas in combination with paclitaxel-carboplatin in treating ovarian cancer (OC). Subsequently, network pharmacology, molecular docking and cell experiments were performed to further verify the underlying molecular mechanism. Thirteen randomized controlled trials, including 922 patients with OC, were enrolled in the study. The results indicated that Poria cocos-based compounds combined with paclitaxel-carboplatin significantly improved patients’ tumor response rate, traditional Chinese medicine syndrome score, Karnofsky Performance Scale, physical and social function, and reduced side effects of chemotherapy compared to the paclitaxel-carboplatin alone. According to the network pharmacological analysis, tumulosic acid were the most bioactive compounds of Poria cocos. BCL2L1 is highly expressed in OC and is associated with a worse prognosis which could become potential drug target. Functional enrichment analysis suggested that the anti-OC effect of Poria cocos may be related to PI3K-Akt signaling pathway. The molecular docking results indicated that tumulosic acid might inhibit OC by regulating BCL2L1. Vitro experiment confirmed tumulosic acid that induced cell apoptosis by modulating PI3K/AKT signaling and BCL2L1. Our study may provide a clinical basis and theoretical rationale for combining Poria cocos-based formulas with chemotherapy for OC. In addition, the integrated pharmacological strategy proposed in our study provides an excellent example for exploring the mechanism of complex formulas.
Large scale synthesis of hexagonal boron nitride nanosheets and their use in thermally conductive polyethylene nanocomposites

Despite their isostructural similarity to graphene, large‐scale preparation of hexagonal boron nitride nanosheets (hBNNs) has been challenging, mainly due to their strong interlayer interactions initiated by the electronegativity difference in their elemental components. In this study, a large‐scale synthesis of hBNNs via a ball milling (BM) technique is reported. The hBN exfoliation was optimized by analyzing the effect of the ball milling process parameters (ball to powder ratio, speed, and time) on the quality and yield of hBNNs. hBNNs prepared at the optimum milling conditions (10:1 ball to powder ratio, 250 rpm rotation speed, and 1.5 hours) were examined in terms of yield, stability, structure, and surface chemistry. The yield of hBNNs was significantly high and reached 38% and 60% at 30 minutes and 4.5 hours milling times, respectively. hBNNs prepared at the optimum milling conditions were utilized to fabricate thermally conductive linear low‐density polyethylene (LLDPE) nanocomposites. The ultimate application of these nanocomposites is replacing metal evaporators in multi‐effect distillation desalination. Therefore, it is a prerequisite to have high thermal conductivity and is essential to have enhanced mechanical durability, thermal stability, and wettability. Thus, the performance of these nanocomposites and conventional composites containing bulk hBN were analyzed in terms of processability, thermal conductivity (κ), and mechanical properties. Finally, a mitigation method to alleviate BM‐induced defects and amorphizations was proposed and investigated. This treatment was essential in alleviating hBNNs defects and enhancing the thermo‐mechanical properties of LLDPE nanocomposites, making them excellent candidates for heat exchanger applications.
Goji Berry Intake Increases Macular Pigment Optical Density in Healthy Adults: A Randomized Pilot Trial

Age-related macular degeneration (AMD) is the third leading cause of blindness worldwide. Macular pigment optical density (MPOD), a biomarker for AMD, is a non-invasive measure to assess risk. The macula xanthophyll pigments lutein (L) and zeaxanthin (Z) protect against blue light and provide oxidant defense, which can be indexed by MPOD. This study examined the effects of Z-rich goji berry intake on MPOD and skin carotenoids in healthy individuals. A randomized, unmasked, parallel-arm study was conducted with 27 participants, aged 45–65, who consumed either 28 g of goji berries or a supplement containing 6 mg L and 4 mg Z (LZ), five times weekly for 90 days. After 90 days, MPOD was significantly increased in the goji berry group at 0.25 and 1.75 retinal eccentricities (p = 0.029 and p = 0.044, respectively), while no changes were noted in the LZ group. Skin carotenoids were significantly increased in the goji berry group at day 45 (p = 0.025) and day 90 (p = 0.006), but not in the LZ group. Regular intake of goji berries in a healthy middle-aged population increases MPOD may help prevent or delay the development of AMD.
Organizational Differences among Universities in Three Socioeconomic Contexts: Finland, Spain and Ecuador. Relational Coordination Approach

The knowledge of local culture is essential to establish competitive strategies in higher education. The objective of this research was to identify the organizational differences among three universities with different international contexts and satisfaction level. An approach was made regarding Relational Coordination (RC) attributes: accurate, frequent and problem-solving communication, shared knowledge, mutual respect and shared goals, by discriminant analysis method. A random sample of 300 students, 100 belonging to each university, was surveyed on the 23 RC variables in 2017–2018. First, the RC variables were evaluated by general linear model (GLM). The three universities—Arcada University of Applied Science (ARCADA) in Finland, University of Cordoba (UCO) in Spain and Agricultural Polytechnic of Manabi “MFL” (ESPAM) in Ecuador—and the two levels of student satisfaction—Low and High—were used as fixed factors. Second, a discriminant model was built with RC variables. A higher level of RC practices concerning to accurate, frequent and problem-solving communication achieved higher levels of satisfaction, regardless of the universities’ socioeconomic context. RC differentiation among three universities showed that shared goals with lecturers and administrative officers and problem-solving communication among classmates were the variables with the highest discriminant power. Two clusters were obtained, where UCO was the most differentiated university. In conclusion, organizational practices made a difference among the three universities. Discriminant analysis can be adapted and extended to different universities to improve quality.
Putting Terror in Its Place: An Experiment on Mitigating Fears of Terrorism among the American Public

An American’s yearly chance of being killed by a terrorist attack sits at roughly 1 in 3.5 million. Yet, over 40 percent of Americans consistently believe that they or their family members are likely to be a terror victim. Can these inflated estimates of the risks of terrorism be brought closer to reality? With trillions of dollars spent on the “War on Terror,” this question is not just theoretically but practically important. In order to investigate, we use an experimental approach assessing whether people update their beliefs about terrorism when given factual information about the relative risks it presents. We find that public fear of terrorism and demand for countering it can be sharply reduced with better information, dropping essentially to pre-9/11 levels after the treatment and staying that way two weeks later. These results suggest that countering the indirect costs of terrorism may largely require providing more context and perspective.
Social function and psychological wellbeing among older Australian users of computer-mediated communication: does social distancing impact use?

ABSTRACT Older adults were at particular risk for loneliness during the height of the COVID-19 pandemic. In this instance, the use of computers for communication (i.e. computer-mediated communication, CMC) may help to enhance older people’s social interactions and relationships. In the present study, 113 community-dwelling users of CMC, aged 65 years and over, were surveyed in order to better understand the effects of CMC in addition to the individual characteristics contributing to patterns of online communication. An opportunity to examine the impact of the pandemic on CMC behaviours presented approximately 12 months after the initial study with 70 participants resurveyed. High levels of social functioning, in addition to good physical and psychological health, were reported by this group of digitally active users. A positive association between high CMC use and social functioning was noted, even after controlling for differences in personality, frequency of face-to-face communication, health, gender, and relationship status. Interestingly, the pandemic saw a reduction in weekly CMC use, although CMC-based behaviours remained unchanged. The present findings highlight the important role that technology has in facilitating and maintaining supports and, potentially, reducing social isolation by helping older adults stay in touch with family and friends.
Delayed interval BNT162b2 mRNA COVID-19 vaccination provides robust immunity

Shortages of COVID-19 vaccines have results in delayed dosing intervals as a strategy to immunize a greater proportion of the population. The effect of this strategy on vaccine immunogenicity is not well studied. Humoral (anti-RBD levels and neutralization) and cellular immune responses were compared in health care workers receiving two doses of BNT162b2 (Pfizer-BioNTech) vaccines at standard (3-6 week) and delayed (8-12 week) intervals. In the delayed group, anti-RBD antibody titres were significantly enhanced compared to the standard interval group. Neutralizing antibody responses were excellent and comparable in both groups. A slight decrease in Spike-specific polyfunctional CD4+ T-cells expressing interferon-γ and IL-2 as well as monofunctional CD4+ T-cells was seen in the delayed group. Both polyfunctional and monofunctional CD8+ T-cell responses were comparable. Our data suggest that the strategy of delayed second dose mRNA vaccination is not overtly detrimental, and specifically may lead to an enhanced humoral immune response.
Stimulus business writing: Using case studies and reports in a cross-cultural Virtual Exchange

ABSTRACT We evaluate the use of a Virtual Exchange (VE) writing task, Stimulus Writing, which we assigned to groups of UK and Finnish business students. There were two learner cohorts in the study: one in the UK (mainly Chinese students), the other in Finland (mainly Finns). The Finnish students wrote authentic case studies about Nordic businesses, while the students in the UK adopted our Stimulus Writing approach to write a report based on a case study given to them by the Finnish students. In Smith & Keng (2017) we reported on the experiences of the Finnish students in the collaboration. In this study, we examine the perceptions of the UK-based Chinese students. They found the approach motivating, and believed that through it their academic English skills improved, as did their understanding of business and culture.
On the Accuracy of uRANS and LES-Based CFD Modeling Approaches for Rotor and Wake Aerodynamics of the (New) MEXICO Wind Turbine Rotor Phase-III

This work presents a comparison study of the CFD modeling with two different turbulence modeling approaches viz. unsteady RANS and LES, on a full-scale model of the (New) MEXICO rotor wind turbine. The main emphasis of the paper is on the rotor and wake aerodynamics. Simulations are carried out for the three wind speeds considered in the MEXICO experiment (10, 15, and 24 ms−1). The results of uRANS and LES are compared against the (New) MEXICO experimental measurements of pressure distributions, axial, radial, and azimuth traverse of three velocity components. The near wake characteristics and vorticity are also analyzed. The pressure distribution results show that the LES can predict the onset of flow separation more accurately than uRANS when the turbine operates in the stall condition. The LES can compute the flow structures in wake significantly better than the uRANS for the stall condition of the blade. For the design condition, the mean absolute error in axial and radial velocity components along radial traverse is less than 10% for both the modeling approaches, whereas tangential component error is less than 2% from the LES approach. The results also reveal that wake recovers faster in the uRANS approach, requiring further research of the far wake region using both CFD modeling approaches.
Memorial Ambivalences in Postcommunist Romania: Generational Attitudes towards the Symbolic Legacy of Communism

After the demise of state socialism, public space became an issue of contention that occupied an important place within societies’ efforts to come to terms with the recent past. Extant scholarship documented extensively how postcommunist societies in Central and Eastern Europe have reconfigured the public space by removing the symbolic presence of the former regime (e.g., monuments and statues, but also place- and street names). However, there is a scarcity of research done on exploring the reception of these broad changes brought to the public statuary and urban nomenclature. In this study, we aim to contribute to this nascent strand of literature by investigating the generational differences in social attitudes towards the symbolic transformation of public space in postcommunist Romania. Data collected through a national web-survey conducted in February 2021 (n = 1156) revealed significant intergenerational differences regarding the removal of monuments and the renaming of streets. In particular, higher approval of such memory work was found among the generations born during communism in comparison to the postcommunist generation. Taking stock of these generational differences, as well as the factors underpinning them, contributes to a better understanding of how ordinary people relate to the politics of memory enacted in transforming societies.
