A network perspective on organizational learning research in tourism and hospitality

Purpose The purpose of this paper is to review existing literature on organizational learning (OL) through networking activities in tourism and hospitality (T&H) research. Referring to theories and concepts from the mainstream literature in OL and inter-organizational network research, the study provides an overview of the existing level of knowledge in T&H research, elaborates theoretical and practical implications and suggests future research directions. Design/methodology/approach A systematic literature review approach was used to identify and analyze relevant literature. The literature search involved six scientific online databases, namely, EBSCOhost, Emerald, ProQuest, Sage, ScienceDirect and Web of Knowledge, which were systematically scanned with defined keywords. Relevant articles were evaluated, selected, analyzed and synthesized to find out what is already known and what is yet to be known. Findings A total of 69 articles were identified that present insights into OL through networking activities in T&H research. The review reveals that the resource, and especially the knowledge-based view of the firm, social capital theory, the relational view and trust and agglomeration theory represent insightful theoretical approaches to study OL phenomena and OL outcomes such as innovation, value creation and competitive advantage. Originality/value According to the author’s information, this paper represents the first attempt to provide a comprehensive review of T&H-specific OL literature from a network perspective. The findings call for increased attention to this research field, especially regarding the adaptation of OL concepts to a T&H-specific context as a networked industry.
COMPANY CHARACTERISTICS ON THE CORPORATE SOCIAL REPORTING INDEX OF CORPORATE SOCIAL AND ENVIRONMENTAL DISCLOSURE IN INDONESIAN PUBLIC COMPANIES

Corporate Social and Environmental Disclosure (CSED) is a form of reporting on the implementation of social and environmental responsibilities that must be included in the company's annual report. However, how extensive or how much information must be delivered is still voluntary. This paper attempts to examine the effect of earnings management, managerial ownership, profitability and firm size on corporate social and environment disclosure. The findings of this study reveal that earnings management, managerial ownership, company size and company profitability have a significant positive effect on the extent of corporate social responsibility and environmental disclosure. This finding encourages the government to stipulate regulations that explicitly and clearly regulate the practice and disclosure, and supervision of Corporate Social Responsibility (CSR) in companies in Indonesia so that the practice and disclosure of CSR in Indonesia is increasing.
A Study of Social Media Usage among Estate Surveyors and Valuers in Real Estate Agency in Uyo, Nigeria

The use of social media in our present society is phenomenal, and this work aims to examine its usage among estate surveyors and valuers (Real Property Practitioners) in Uyo, Akwa Ibom State, Nigeria. There was an enumeration survey of thirty-six (36) estate surveying and valuation firms in Uyo. The data were analyzed using simple percentages and relative importance index. In the study, it was found that all firms and their clients have made use of social media and that Facebook, WhatsApp, and Twitter are the most used social media by estate firms. The study also found that some of the challenges encountered by estate surveyors and valuers in their use of the social media platforms include network issues, the high cost of data, unawareness of the platform and non-availability of power, etc. It amongst other matters suggested the production of practice guidelines on the use of social media by relevant regulatory bodies and agencies.
Hydrogen sulfide against preeclampsia exposure-induced oxidative mitochondrial damage in HTR-8/SVneo cells

Extravillous trophoblast invasion disorder caused by oxidative stress is involved in the pathogenesis of preeclampsia (PE). In order to identify whether hydrogen sulfide (H2S) can prevent oxidative stress injury in extravillous trophoblasts. HTR-8/SVneo cells were detected by H2S inhibiting H2O2 induced oxidative mitochondrial damage. Reactive oxygen species (ROS) were detected, as well as malondialdehyde (MDA), catalase (CAT), and superoxide dismutase (SOD). JC-1 detected the potential of the mitochondrial membrane in this experiment. Then to detect the expression level of the apoptosis-inducing protein B-cell lymphoma-2 (Bcl-2) associated X protein (Bax), caspase 3, p53, p-p53, the apoptosis-inhibiting protein Bcl-2, PRAP, and the mitochondria fission protein Drp1, p-Drp1. CCK-8 assay, it was demonstrated that cell proliferation in the NaHS group was significantly higher than that in the Mod group, indicating that H2S may induce cell proliferation. Transwell assay elucidated that cell invasion in the NaHS group was recovered compared to the Mod group. ROS concentration no matter in cells or mitochondria was decreased by NaHS, which we could get from the comparison between the Mod group, PAG group, and NaHS group. The concentration of MDA was significantly lower in the NaHS group, and the concentration of SOD was extremely high in the NaHS group. Utilized JC-1 to detect mitochondrial membrane potential and found that cells from the NaHS group had a stable potential while cells from the Mod group and PAG group partly lost their potential, which could demonstrate that NaHS could maintain mitochondrial membrane potential. The western blot results revealed that p-Drp1 had a significant decline in the NaHS group, which means mitochondria fission was decreased in the NaHS group. The expression level of Bax and caspase 3 was significantly lower than in the Mod group and PAG group, and the expression level of Bcl-and PRAP was significantly higher in the NaHS group. That could prove that NaHS protect HTR-8/SVneo cell by inhibiting cell apoptosis. These promising results show that H2S elicits its effects on cell apoptosis by decreasing ROS concentration, maintaining mitochondrial membrane stability, and promoting apoptosis-inhibiting protein expression in cells.
Financial literacy and voluntary savings for retirement: novel causal evidence

ABSTRACT We utilise recent Household Finance and Consumption Survey microdata to report first causal effects of financial literacy on voluntary private pension schemes participation for a Central and Eastern European (CEE) country, namely Slovakia. Savings for retirement in the supplementary pension schemes are positively associated with financial literacy after controlling for a set of relevant socio-economic variables. One additional correctly answered financial literacy question leads to a 5.6 percentage points increase in the probability of having a voluntary pension savings plan in our ordinary least squares estimates. The causal impact of financial literacy increases to 19.5 percentage points when we address potential endogeneity problems by novel to the literature instrumental variables.
Global Risks in the Currency Market

Global risks allow theoretical models of the currency market to explain currency risk premia. Yet, there is no consensus in the empirical literature on which factors can represent global risks. We develop an asset pricing test for global risk factors that relies on the key assumption of a distinct U.S. global risk exposure. Using numeraire-invariant test assets that are particularly suitable for studying global risks, we apply the test on a large set of factors used in recent studies of currency risk. We find that only equity market risk can represent a global risk in the currency market.
Estimating the Cost of Capital for Renewable Energy Projects

Many models in energy economics assess the cost of alternative power generation technologies. As an input, the models require well-calibrated assumptions for the cost of capital or discount rates to be used, especially for renewable energy for which the cost of capital differs widely across countries and technologies. In this article, we review the spectrum of estimation methods for the private cost of capital for renewable energy projects and discuss appropriate use of the methods to yield unbiased results. We then evaluate the empirical evidence from 46 countries for the period 2009–2017. We find a globally consistent rank order among technologies, with the cost of capital increasing from solar PV to onshore wind to offshore wind power. On average, the cost of capital in developing countries is significantly higher than in industrialized countries, with large heterogeneity also within the groups of industrialized or developing countries.
How valid are 11‐plus tests? Evidence from Kent

Despite profound influence of selection-by-ability on children’s educational opportunities, empirical evidence for validity of 11-plus tests is scarce. This study focused on secondary selection in Kent, the largest grammar school area in England. We analysed scores from the ‘Kent Test’ (the 11-plus test used in Kent), Cognitive Assessment Tests (CAT4), and Key Stage 2 Standardised Assessment Tests (KS2) using longitudinal data of two year cohorts (N1=95, N2=99) from one primary school. All the assessment batteries provided highly overlapping information, with the decisive effect of content area (e.g. verbal versus maths) over task type (e.g. knowledge-loaded versus knowledge-free). Thus, the value in differentiating ‘pure’ (i.e. knowledge-free) ability in 11-plus testing is questionable. KS2 and Kent Test aggregated scores overlapped very strongly, sharing nearly 80% of variance; moreover, KS2-based eligibility decisions had higher sensitivity than the Kent Test in predicting the actual admissions to grammar schools after Head Teacher Assessment (HTA) appeals have taken place. Finally, the use of multiple pass marks for each Kent Test component as well as the total score was found to increase the chance of false rejection. This study provides preliminary evidence that national examinations could be a good basis for selection to grammar schools; it challenges the use of complex admission rules and multiple decisions and questions the value of 11-plus tests.
Life-stage dependent response of the epiphytic lichen Lobaria pulmonaria to climate

Lichens are poikilohydric organisms, whose internal water content tends to reflect external humidity conditions. After drying, they can reactivate their metabolic activity through water vapor uptake or liquid water input. Thus, lichen water-related functional traits are important as they are involved in the duration of the hydrated period. Models predicting the effect of environmental conditions on lichens are based mainly on the presence or absence of adult thalli. Nevertheless, ecological conditions required by lichens might vary during their life cycle, for example during propagule establishment or in the first stages of thallus development. Little is known about the different ecological requirements at the different development stages in lichens. In this work, we measured water holding capacity (WHC) and specific thallus mass (STM) of adult and juvenile thalli of the model species Lobaria pulmonaria along a climatic gradient to constrain the process-based model LiBry. The LiBry model allows accounting for the productivity of lichens with different physiological strategies under various environmental conditions. We simulated the activity and performance of adult and juvenile thalli in 9 regions of Italy and Corsica. The model was used to test if adult thalli of L. pulmonaria have a higher survival probability due to their higher aerodynamic resistance. In the current climatic condition, the LiBry model predicts a higher survival probability of adults with decreasing absolute survival rates of both life stages with increasing temperature. Adult thalli also result in having higher active time, STM, and relative growth rate (RGR). We discuss the main implications of our simulation outputs, provide future perspectives and possible implementations of the LiBry model.
DETERMINANTES DA UTILIZAÇÃO DE COVENANTS CONTÁBEIS NAS DEBÊNTURES EMITIDAS PELAS EMPRESAS LISTADAS NA BOLSA BRASIL BALCÃO

Os covenants contabeis tem como finalidade reduzir potenciais conflitos de agencia entre empresa e credores, bem como reduzir o risco relacionado a incerteza quanto a futura capacidade de pagamento da divida. Os fatores que direcionam o uso dos covenants variam em funcao do pais ou tipo de divida contratada, podendo afetar tanto a decisao de utilizar (ou nao) covenants quanto a quantidade utilizada. Nesse contexto, o objetivo desta pesquisa e identificar fatores determinantes da utilizacao de covenants contabeis nas debentures emitidas no Brasil. Este estudo justifica-se pela caracteristica brasileira de baixa protecao aos direitos dos credores, o que tende a aumentar a importância dos covenants como mecanismo complementar de protecao ao capital fornecido. A amostra analisada e composta por 287 debentures emitidas entre 2010 e 2016 pelas empresas listadas na Bolsa Brasil Balcao. Para a identificacao dos determinantes da utilizacao de covenants contabeis, foram especificados modelos de regressao logistica e de Poisson com dados em painel com 10 variaveis testadas, as quais representam: (a) caracteristicas economicas e financeiras das empresas; (b) caracteristicas de governanca corporativa, e; (c) caracteristica da divida. Os resultados indicam que as caracteristicas da divida somente afetam a decisao de se utilizar (ou nao) covenants contabeis, enquanto as caracteristicas das empresas (economicas e governanca) afetam tanto a decisao de utilizacao quanto a quantidade de covenants contabeis utilizada. Como contribuicao pratica, este estudo mostra que as empresas podem adotar mecanismos substitutos a utilizacao de covenants contabeis e, assim, evitar as restricoes a flexibilidade financeira impostas por eles. Esses mecanismos consistem na emissao de dividas com prazo mais curto, emissao de divida com garantia real ou, ainda, o reforco das caracteristicas internas de governanca corporativa.
Efficacy of PD-1/PD-L1 inhibitors in patients with advanced gastroesophageal cancer: An updated meta-analysis based on randomized controlled trials

Background: This study aimed to investigate the clinical efficacy of programmed death-1 receptor and ligand-1 (PD-1/PD-L1) inhibitors in gastroesophageal cancer patients and the relationship between their clinicopathological features and curative treatment effects. Methods: A systematic search was conducted for articles published before April 2022 from online databases (PubMed, EMBASE, Web of Science and the Cochrane Library). The main outcome was overall survival (OS). Results: This meta-analysis comprised 16 studies involving 9,304 participants. The results indicated that compared with chemotherapy, patients treated with PD-1/PD-L1 inhibitors had significantly improved OS (HR = 0.80; p < 0.001) but no significant improvement in progression-free survival (PFS) (p = 0.185). Subgroup analyses demonstrated that PD-1/PD-L1 inhibitors combined with chemotherapy, esophageal squamous cell carcinoma, male, Asian patients and combined positive score (CPS) ≥1 were significantly associated with better survival outcomes. Further, subgroup analysis of gender revealed that the OS of all subgroups containing male patients was significantly improved compared with chemotherapy, unlike that of female patients. In addition, the line of therapy, Lauren classification, age and eastern cooperative oncology group (ECOG) performance status were not associated with PD-1/PD-L1 inhibitors efficacy. Conclusion: The results indicated that PD-1/PD-L1 inhibitors could prolong the OS of advanced gastroesophageal cancer patients. Clinicopathological features such as therapeutic schedules, tumor types, histological type, gender, geographical region and PD-L1 expression status (CPS) seemed to be associated with survival outcomes.

Based on the results of multiple linear analyses the effect of service quality on customers satisfaction of Islamic banking in West Java is 70.1% while the remaining 29.9% is influenced by other variables which are not examined in this study. © 2019 by the authors; licensee Growing Science, Canada
Making sense of neural machine translation

The last few years have witnessed a surge in the interest of a new machine translation paradigm: neural machine translation (NMT). Neural machine translation is starting to displace its corpus-based predecessor, statistical machine translation (SMT). In this paper, I introduce NMT, and explain in detail, without the mathematical complexity, how neural machine translation systems work, how they are trained, and their main differences with SMT systems. The paper will try to decipher NMT jargon such as “distributed representations”, “deep learning”, “word embeddings”, “vectors”, “layers”, “weights”, “encoder”, “decoder”, and “attention”, and build upon these concepts, so that individual translators and professionals working for the translation industry as well as students and academics in translation studies can make sense of this new technology and know what to expect from it. Aspects such as how NMT output differs from SMT, and the hardware and software requirements of NMT, both at training time and at run time, on the translation industry, will be discussed.
The significance of coastal bathymetry representation for modelling
the tidal response to mean sea level rise in the German Bight

Abstract. Due to climate change an accelerated mean sea level rise is expected. One key question for the development of adaptation measures is how mean sea level rise affects tidal dynamics in shelf seas such as the North Sea. Owing to its flat coastal areas, especially the German Bight (located in the south-east of the North Sea) will be affected. Numerical hydrodynamic models help to understand how mean sea level rise changes tidal dynamics. By definition models cannot represent all processes in overall detail. One limiting factor is the resolution of the model grid. In this study we investigate which role the representation of the coastal bathymetry plays when analysing the response of tidal dynamics to mean sea level rise. Using a shelf model including the whole North Sea and a high-resolution hydrodynamic model of the German Bight we investigate the changes in M2 amplitude due to a mean sea level rise of 0.8 m and 10 m. To the mean sea level rise of 0.8 m the shelf model and the German Bight Model react in different ways. In the shelf model the M2 amplitude generally increases in the region of the German Bight. In contrast, the M2 amplitude in the German Bight Model increases only in some coastal areas and decreases in the northern part of the German Bight. In two case studies we adjust the German Bight Model in order to more closely resemble the shelf model. We find that a different resolution of the bathymetry results in different energy dissipation changes in response to mean sea level rise. Our results show that the resolution of the bathymetry especially in flat intertidal areas plays a crucial role for modelling the impact of mean sea level rise in the order of 1 m. For higher mean sea level rise scenarios (10 m) the resolution of the bathymetry is less important.
Gender-related differentially expressed genes in pancreatic cancer: possible culprits or accomplices?

Pancreatic cancer (PC) is one of the leading causes of cancer mortality worldwide, and its incidence and mortality rate in several regions is higher in male patients. Although numerous efforts have been made to enhance the clinical outcomes of existing therapeutic regimens, their efficiency is still low, and drug resistance usually occurs in many patients. In addition, the exact underlying molecular basis that makes PC slightly more prevalent among males remains unknown. Providing information regarding the possible association between gender and PC tumorigenesis may offer important clues for how certain molecular cross-talks can affect PC initiation and/or progression. In this study, we used several microarray expression data to identify the common up- and downregulated genes within one specific gender, which were also specified to have binding sites for androgen and/or estrogen receptors. Using functional enrichment analysis among the others, for all the gene sets found in this study, we have shed light on the plausible importance of the androgenic effectors in tumorigenesis, such as the androgen-regulated expression of the GLI transcription factor and the potential role of testosterone in the extracellular matrix (ECM)–cell interaction, which are known for their importance in tumorigenesis. Moreover, we demonstrated that the biological process axon guidance was highlighted regarding the upregulated genes in male patients. Overall, identification of gene candidates as the possible link between gender and PC progression or survival rates may help in developing strategies to reduce the incidence of this cancer.
