Addicted to cruises? Key drivers of cruise ship loyalty behavior through an e-WOM approach
Authors: Castillo-Manzano José Ignacio , Castro-Nuño Mercedes , Pozo-Barajas Rafael 
Published: November 2021

Purpose
This paper aims to identify the drivers that explain loyalty behavior in cruise tourism with the aim of achieving a better understanding of repeat cruisers’ intentions to sail on the same ship or on another ship belonging to the same cruise line or cruise corporation.

Design/methodology/approach
Based on over 150,000 online reviews about their satisfaction and experience posted by cruisers using so-called electronic Word of Mouth (e-WOM), the authors apply both a graphic and an econometric technique through input-output circular plots and discrete choice models.

Findings
The main results show that cruisers’ behavior is influenced by multiple onboard attributes, such as the service crew, entertainment options, type of cabin, some characteristics of the ship (age, capacity) and the cruise line (Premium-Luxury versus mainstream), and, specifically, the quality and variety of the gastronomic experience.

Practical implications
The results highlight that repeats cruisers are predominantly linked to a cruise company or a cruise corporation rather than a particular ship. This result provides information on the moderators that can influence the customers’ repetition behavior, which might be useful for planning revenue management and extending knowledge on hospitality loyalty in general and in the cruise industry in particular, specifically under the current uncertainty due to the COVID-19 pandemic.

Originality/value
The previous literature has essentially examined revisit intentions in the cruise market from a qualitative approach and the authors have found no study to date that has simultaneously addressed this issue in three dimensions, namely, ship, cruise line and cruise corporation. The research fills this gap by determining the reasons why passengers would repeat a cruise either on the same ship, with the same cruise line or the same cruise corporation based on previous experience.

Published: November 2021

PurposeMoral aspects of food are gaining increased attention from scholars due to growing complexity of the food system. The foodservice system is a complex arrangement of stakeholders, yet has not benefited from similar scholarly attention on the moral facets. This gap is of significance given that the foodservice system has increased in importance with the larger proportion of food consumed in foodservice environments. This paper aims to focus on the foodservice system with the goal of applying moral perspectives associated with the theoretical discussion on the principles of food ethics.Design/methodology/approachFood ethics is described within the theoretical framework of three principles, namely, autonomy, justice and well-being. These ethical principles are reviewed in context of the foodservice system comprised of food distribution (supply chains), preparation (foodservice establishments) and consumption (consumer demand). The review also includes international perspectives on foodservice system ethics to assess relativism (versus universalism) of moral issues.FindingsAs the foodservice system increases in complexity, greater discussion is needed on the ethics of this system. This study observes that ignoring ethical principles can negatively impact the ability of consumers, businesses and communities to make informed choices, and on their well-being. Alternatively, a focus on understanding the role of food ethics can provide an anchor for research, practice and policy development to strengthen the foodservice system. While these moral principles are universal truths, they will require relative introspection globally, based on local experiences.Originality/valueThis paper presents a moral principle-based description of food ethics that incorporates the various components of the expanding foodservice system.
Do green features increase housing value in Malaysia?
Authors: Goh Zhen-Ting , Low Sheau-Ting , Choong Weng-Wai , Wee Siaw-Chui 
Published: November 2021

Purpose
The purpose of this paper is to identify the perception of valuers towards the contribution of green features in residential property valuation. The concept of green housing was designed to reduce the negative impacts on the environment and humans. The cost of green housing is higher than the conventional building and is reflected in the selling price, which is further enhanced by the increasing demand for green buildings in the housing market. Such a scenario could be a challenge to the valuers when they carry out a valuation on housing with green features, as there is a lack of information to guide valuers.

Design/methodology/approach
This study used a quantitative research method. A comprehensive review of the international green rating tools was carried out to ascertain the relative green features in residential buildings. There are 14 green features identified and grouped into four main categories. A total of 147 valid responses were collected by an online platform and face-to-face distribution among licensed valuers in Malaysia.

Findings
The result confirmed that the 14 green features are contributing to the residential property valuation with a reasonable range of adjustment from 2.0% to 6.5%.

Originality/value
The understanding of the range of adjustment for each green feature may provide a guide to the valuer in determining the range of adjustment based on green features associated with residential property in Malaysia. The findings contribute ideas and options to the future development of residential projects by taking into consideration the specific green features that potentially lead to environmental sustainability and building value.
Investigating digital technological competencies amongst black Asian minority ethnic construction students in the UK
Authors: Balogun Teslim Bamidele , Awonuga Olukayode Olusola , Abowen-Dake Rukaya 
Published: November 2021

Purpose
This study aims to investigate digital technology (DT) competencies, training and awareness amongst Black Asian Minority Ethnic (BAME) construction students in the UK.

Design/methodology/approach
This study uses a quantitative online survey to investigate both BAME Construction Undergraduates Graduate Students (CUGS) and staff studying on and teaching on Construction programmes. The investigation examined their opinions as to their own awareness of their competencies and training regarding DT.

Findings
Findings indicate that BAME CUGS were mostly “very proficient” in the use of basic DT, such as required to complete an authentic assessment that typifies a real-life scenario. For example, sending and receiving emails, Excel, Word, computer literacy/basic IT skills, browsing searching materials, PowerPoint, specialist IT skills, mobile devices, tablet and social media handles. However, findings revealed that training awareness and competencies in new DT is shallow, and BAME CUGS are probably not ready for the digitalised construction world. Respondents were mainly within the “probably aware” range, and very few were within the “definitely aware” range, on the Likert scale adopted. New DTs that fell within the “definitely aware” range are BIM, offsite construction and manufacturing, 3D printing, cloud computing and collaboration.

Research limitations/implications
It is acknowledged that expanding the sample size to other universities and exploring BAME industry professionals’ narratives could further enrich the discussion. However, these limitations did not impact the robust practical and theoretical implications provided to CUGS, Higher Education (HE)sectors, University staff and industry emerging from the analysis and findings achieved in the study. Still, it is being recommended for future work to consider.

Originality/value
The study provides valuable recommendations helpful to HE institutions, industry and government. Recommendations provided include a need to review and update the current curriculum, robust partnership between academia and industry, increase government funding, upskilling and training staff in the new DT.

Authors: Tyagi Sunil 
Published: November 2021

Purpose
This study aims to measure the global research landscape on Pharmacovigilance (PV) indexed in the Scopus database for six years period spanning from 2015 to 2020. The study examines growth rate, author productivity and prominent authors, institutions and countries.

Design/methodology/approach
The research literature on PV published globally and indexed in the Scopus core collection database was retrieved using the search string “pharmacovigilance” as per the Medical List of Subject Heading. A total of 1,272 documents were retrieved based on the query set. Quantitative and visualization technologies were used for data analysis and interpretation. Network visualization maps including research collaboration of authors, journals, institutions and countries were created by using the VOSviewer program.

Findings
A total of 1,272 global scientific research output on PV were retrieved with an annual average growth rate of 21.70% and with a proportion of 3.84% compound annual growth rate. The relative growth rate for the world’s PV publications decreased gradually from the rate of 0.71 to 0.20. On the other hand, the doubling time (DT) of PV publications displays an increasing trend from the rate of 0.97 to 3.46. The mean relative growth and DT of PV publication for six years is 0.32 and 1.87, respectively. The global publications on PV registered a total of 6,387 citations with an average citation impact of 5.02 citations per paper. The average number of authors per paper was 0.76 and the average productivity per author was 1.33. The most productive journal was Drug Safety with a total of 74 papers. France has the highest number of publications with a total of 251 papers accounting for 19.73%. Uppsala Monitoring Center, Sweden dominated in research productivity on PV with a proportion of 1.89% papers. There is a considerable research output in the areas of medicine accounting for 77.43% of total publications.

Practical implications
The outcome of the study may help regulators, drug manufacturers, medical scientists and health-care professionals to identify the progress in PV research. In addition, it will also help to identify the prolific authors, journals, institutions and countries/territories in the development of research.

Social implications
PV across the globe has become an important public health issue concerning to regulators, drug manufacturers and health-care professionals, therefore, it is feasible to know the research landscape to safeguard of public health.

Originality/value
The investigation is the first attempt to the scientometric assessment of PV research output at the global level.
Energy‐mediated responses to changing prey size and distribution in marine top predator movements and population dynamics
Authors: Gallagher Cara A. , Chimienti Marianna , Grimm Volker , Nabe‐Nielsen Jacob 
Published: November 2021

Abstract

Climate change is modifying the structure of marine ecosystems, including that of fish communities. Alterations in abiotic and biotic conditions can decrease fish size and change community spatial arrangement, ultimately impacting predator species which rely on these communities. To conserve predators and understand the drivers of observed changes in their population dynamics, we must advance our understanding of how shifting environmental conditions can impact populations by limiting food available to individuals.

To investigate the impacts of changing fish size and spatial aggregation on a top predator population, we applied an existing agent‐based model parameterized for harbour porpoises Phocoena phocoena which represents animal energetics and movements in high detail. We used this framework to quantify the impacts of shifting prey size and spatial aggregation on porpoise movement, space use, energetics and population dynamics.

Simulated individuals were more likely to switch from area‐restricted search to transit behaviour with increasing prey size, particularly when starving, due to elevated resource competition. In simulations with highly aggregated prey, higher prey encounter rates counteracted resource competition, resulting in no impacts of prey spatial aggregation on movement behaviour.

Reduced energy intake with decreasing prey size and aggregation level caused population decline, with a 15% decrease in fish length resulting in total population collapse Increasing prey consumption rates by 42.8 ± 4.5% could offset population declines; however, this increase was 21.3 ± 12.7% higher than needed to account for changes in total energy availability alone. This suggests that animals in realistic seascapes require additional energy to locate smaller prey which should be considered when assessing the impacts of decreased energy availability.

Changes in prey size and aggregation influenced movements and population dynamics of simulated harbour porpoises, revealing that climate‐induced changes in prey structure, not only prey abundance, may threaten predator populations. We demonstrate how a population model with realistic animal movements and process‐based energetics can be used to investigate population consequences of shifting food availability, such as those mediated by climate change, and provide a mechanistic explanation for how changes in prey structure can impact energetics, behaviour and ultimately viability of predator populations.
The ability to disperse large seeds, rather than body mass alone, defines the importance of animals in a hyper‐diverse seed dispersal network
Authors: Ong Lisa , McConkey Kim R. , Campos‐Arceiz Ahimsa 
Published: November 2021

Abstract

Large‐bodied animals play irreplaceable roles in seed dispersal, partly due to their capacity to disperse large seeds. Understanding this role at a community level has been limited by the paucity of network studies that include large vertebrates, and the almost complete absence of studies including synzoochoric dispersers. Synzoochoric dispersers can disperse seeds disproportionately large for their body size, potentially overlapping the roles of large‐bodied animals. A comprehensive network, inclusive of large vertebrates and synzoochorous dispersers, is imperative to understand seed dispersal at a community level.

Here, we analysed the seed dispersal network of a hyper‐diverse Sundaic forest in Malaysia using local ecological knowledge and including multiple forms of endozoochorous and synzoochorous dispersal. We evaluated the extent to which three disperser traits: body mass, seed‐handling ability (size of the largest seed dispersed) and diet explained the importance of animals in the network. We evaluated dispersers' relative importance using four network metrics—degree of specialisation (nested rank), species strength, within‐module connectivity (z‐value) and between‐modules connectivity (c‐value).

We found that seed‐handling ability had the biggest effect on a disperser's importance, with strong effects on three network metrics (species strength, ecological specialisation and z‐value) and moderate effects on connectivity between modules. Body mass was important in defining interactions within modules, and dietary differences defined the ecological specialisation of species in seed dispersal.

Important dispersers in our network were large‐seed dispersers (e.g. rats, gibbons), large‐bodied animals, in particular the Asian elephant, and animals with frugivorous diets such as hornbills.

Synthesis. Our work uncovers the significance of seed‐handling ability in identifying pivotal seed dispersal roles in tropical rainforests. Key dispersers include large‐bodied herbivores and medium‐sized frugivores that could disperse large seeds by endozoochory, and smaller rodents that dispersed similar‐sized seeds by synzoochory. Many of the species that emerged as particularly important for the seed dispersal network are currently threatened (e.g. the Asian elephant, gibbons and hornbills). Their protection or reintroduction should be a top conservation priority.
Mycorrhizal symbiosis alleviates plant water deficit within and across generations via phenotypic plasticity
Authors: Puy Javier , Carmona Carlos P. , Hiiesalu Inga , Öpik Maarja , de Bello Francesco , Moora Mari 
Published: November 2021

Abstract

Phenotypic plasticity is essential for organisms to adapt to local ecological conditions. It is expected that mutualistic interactions, such as arbuscular mycorrhizal (AM) symbiosis, mediate plant phenotypic plasticity, although it is not clear to what extent this plasticity may be heritable (i.e. transgenerational plasticity).

We tested for plant plasticity within‐ and across‐generations in response to AM symbiosis and varying water availability in a full factorial experiment over two generations, using a genetically uniform line of a perennial apomictic herb, Taraxacum brevicorniculatum. We examined changes in phenotype, performance and AM fungal colonization of the offspring throughout plant development.

AM symbiosis and water availability triggered phenotypic changes during the life cycle of plants. Additionally, both factors triggered adaptive transgenerational effects especially detectable during the juvenile stage of the offspring. Water deficit and absence of AM fungi caused concordant plant phenotypic modifications towards a ‘stress‐coping phenotype’, both within and across generations. Parental environment also affected AM fungal colonization of the offspring. Juvenile offspring of amply watered parents and adut offspring of mycorrhizal parents had increasing length of root colonized by AM fungi when they were under water stress.

Synthesis. We show that, in addition to providing beneficial transgenerational effects in offspring traits proxies of fitness (such as increased biomass, survival or nutritional status), AM symbiosis can trigger transgenerational plasticity in anatomical and physiological traits related to resource‐use acquisition, and further influence offspring AM fungal colonization. Our results show that AM symbiosis could improve plants' ability to cope with environmental stress, not only within, but also across generations.

Authors: Jiménez‐Gutiérrez José M. , García‐Juárez Ignacio , Olivas‐Martinez Antonio , Ruiz Isaac 
Published: November 2021

ObjectiveThis study aimed to evaluate outcomes in cirrhotic patients diagnosed with spontaneous bacterial empyema (SBE) compared with those without this complication.MethodsWe performed a retrospective cohort study of cirrhotic patients from a tertiary care center. The primary outcome was time to death or liver transplantation (LT) within one year after diagnosis of infection. We integrated three groups: patients with SBE (group A), patients with spontaneous bacterial peritonitis (SBP; group B), and cirrhotic patients without SBP or SBE (group C), matched by age, model for end‐stage liver disease‐sodium (MELD‐Na) score and year of infection. Outcomes were analyzed using a Cox regression model adjusted for cardiovascular risk factors and MELD‐Na score.ResultsBetween January 1999 and February 2019, 4829 cirrhotic patients were identified. Among them, 73 (1.5%) had hepatic hydrotorax, of whom 22 (30.1%) were diagnosed with SBE. Median age in group A was 58 years, 50% were men, and median MELD‐Na was 21.5. Compared with group C, the hazard ratio of death or LT during the first year after infection was 2.98 (95% confidence interval [CI] 1.43‐6.22, P = 0.004) for group A and 1.23 (95% CI 0.65‐2.32, P = 0.522) for group B.ConclusionsOur results suggest that patients with SBE have a worse outcome during the first year after infection is diagnosed. Patients who develop SBE should be promptly referred for transplant evaluation. SBE may emerge as new indication that could benefit from MELD exception points.
Autochthonous fungi are central components in microbial community structure in raw fermented sausages

Published: November 2021

SummaryRaw meat sausage represents a unique ecological niche rich in nutrients for microbial consumption, making it particularly vulnerable to microbial spoilage. Starter cultures are applied to improve product stability and safety as well as flavour characteristics. However, the influence of starter cultures on microbial community assembly and succession throughout the fermentation process is largely unknown. In particular the effect on the fungal community has not yet been explored. We evaluate the microbiological status of four different raw meat sausages using high‐throughput 16S rRNA gene and ITS2 gene sequencing. The objective was to study temporal changes of microbial composition during the fermentation process and to identify potential keystone species that play an important role within the microbial community. Our results suggest that fungi assigned to the species Debaryomyces hansenii and Alternaria alternata play a key role in microbial community dynamics during fermentation. In addition, bacteria related to the starter culture Lactobacillus sakei and the spoilage‐associated genera Acinetobacter, Pseudomonas and Psychrobacter are central components of the microbial ecosystem in raw fermented sausages. Elucidating the exact role and interactions of these microorganisms has the potential to have direct impacts on the quality and safety of fermented foods.
