Synthesis of novel dyes based on thiophene analogues with antibacterial activity for dyeing polyester fabrics
Authors: Abomelha Hanna 
Published: May 2019

Purpose
This study aims to the synthesis of some novel 4-arylazo-3-hydroxythiophene analogues containing sulphapyridine and sulphathiazole dyestuffs and studying their application in dyeing polyester fabrics and rendering their antibacterial efficacy.

Design/methodology/approach
Simultaneous dyeing and antibacterial finishing for polyester fabric using a new antibacterial disperse dye having a modified chemical structure to thiophene dyes were studied. Construction of the thiophene dyes was carried out by diazo-coupling of diazotized sulphonamide-containing heterocyclic rings sulphapyridine and sulphathiazole with ethyl α-phenylthiocarbamoyl-acetoacetate followed by cyclizing the produced 2-arylazo-thioacetanilide with various α-halogenated reagents. All newly synthesized compounds were characterized by elemental analysis and extensive study of their spectral data (IR and 1H-NMR). The dyeing characteristics of these thiophene dyestuffs were evaluated at optimum conditions. Antibacterial activities of the obtained thiophene dyes were studied against some Gram-positive and Gram-negative bacteria.

Findings
The synthesized thiophene-containing sulphonamides dyes were applied on polyester fabric. The modified dyes exhibited a good fastness properties and antibacterial efficacy against some Gram-positive and Gram-negative bacteria. Synthesized dyes showed higher antibacterial potency than the reference standard drug.

Research limitations/implications
Synthesis of these disperse azo dyes for textile dyeing had never been reported previously.

Practical implications
The dyestuffs derived from thiophene are reasonable azo disperse dyestuffs giving good all-round fastness properties on polyester fabrics.

Originality/value
Thiophene dyes are used for dyeing polyester fabrics with brilliant colour and good fastness properties. The presence of sulphonamides moieties increase their fastness properties and elevate their antibacterial properties. Moreover, they can be used as antimicrobial finish due to their bactericidal properties on dyed textiles. This work afforded a new thiophene colorant that can be used in many different uses like polyester packing, thread Surgery, blends and other uses in medical textile.
Orientation towards social responsibility of North-West African firms
Authors: Sánchez-Hernández M. Isabel , Carvalho Luísa Cagica , Paiva Inna Sousa 
Published: May 2019

Purpose
Corporate social responsibility orientation (CSRO) is considered a crucial strategy to enhance long-term competitiveness around the world, and it is starting to be a broader issue in Africa. Based on recent works addressing the CSRO–performance relationship in countries outside the African continent, this paper aims to assess CRSO in North-West Africa.

Design/methodology/approach
In this study a questionnaire was distributed among 122 managers in two countries in North-West Africa: Guinea-Bissau and the Ivory Coast. Partial least squares (PLS) structural equation modelling (SEM) is used to assess the path or relationships for the North-West African context.

Findings
The results show that there is a generally positive perception of the economic, social and environmental dimensions of CSRO, although special emphasis is laid on the economic and social issues, mainly when they are related to human resources. The study also revealed the important role of innovation as mediator between CSRO and firm performance.

Practical implications
The study points out the role of managers in promoting a culture of social innovation by focussing on the CSR philosophy for improving the competitive success of African businesses.

Social implications
The social, economic and legal contexts of Guinea-Bissau and the Ivory Coast are vulnerable. The findings raise concerns about whether governments and regulatory efforts improve the development of the strategies towards social responsibility of African firms and whether they also increase the role of the firms in producing positive externalities to the market through CSRO.

Originality/value
Very few studies have investigated CSRO in Africa. Aiming to switch from the current CSRO in developed countries to an African perspective of CSRO, this paper contributes to filling the existing gap through the study of managers’ perceptions about CSR in two countries in North-West Africa: Guinea-Bissau and the Ivory Coast.
Corporate sustainability accounting information systems: a contingency-based approach
Authors: Dagiliene Lina , Šutiene Kristina 
Published: May 2019

Purpose
This paper aims to explore the development of sustainability accounting information systems through lens of contingency theory. In this digital age when companies are confronted with massive sets of data, integration of financial and non-financial data, little empirical evidence exists on how sustainability issues are integrated or linked within internal corporate information systems.

Design/methodology/approach
A questionnaire-based survey, hypothesis testing, principal component methods and hierarchical clustering are used to provide original empirical evidence from major Lithuanian companies.

Findings
The main findings reveal that most companies surveyed include a sustainability strategy in their core strategy, but there is a lack of linkage with measuring and integrating sustainability outcomes within the entirety of corporate financial results. Unexpectedly, the association between stakeholders' involvement and sustainability accounting information system design was not as strong as hypothesized theoretically. Therefore, it deserves further investigation, constituting an important implication for future research. Specifically, three profiles of sustainability accounting information systems were explained, namely, integrated, fragmented and compliance systems.

Research limitations/implications
The limitations of this study relate to the small sample size, as sustainability-related information is still regarded quite confidential.

Practical implications
This result could serve as a specific reference for companies to apply integrated sustainability accounting information systems that might serve as a good practice model for companies, however, fragmented and compliance profiles are the prevailing ones.

Social implications
The findings are important for fostering corporate social responsibility by developing sustainability accounting information systems.

Originality/value
This paper contributes to the sustainability accounting and information systems literature by providing empirical evidence linking contingent factors with the development of sustainability accounting information systems.
The growth and development of the cruise sector: a perspective article
Authors: Papathanassis Alexis 
Published: May 2019

Purpose
The cruise sector has undergone a significant transformation over the past decades, rendering it amongst the fastest growing tourism segments. Nevertheless, cruise holidays represent a relatively small fraction of the entire tourism sector; and so do their economic impacts and externalities. The cruise business has emerged as a result of technological developments in passenger air-transportation and the resulting decline of passenger-shipping. While the increased visibility and over-exposure of its market and product developments may have enabled the re-invention and growth of the cruise sector, they are also amplifiers for its economic and sustainability risks. The purpose of this paper is to relativise both the potential risks and benefits to contribute to more pragmatism in future destination development investments and policies.

Design/methodology/approach
Based on a brief historical analysis of cruising and current trends, a realistic future is painted where the passenger and capacity growth rates of cruise tourism gradually level out.

Findings
Moreover, the cruise business becomes increasingly technologically driven to maintain profitability and establish its position in the wider experience portfolio of holiday consumers.

Originality/value
Traditionally, the relevance argument for cruise tourism research is based on the reported sector's growth rates and corresponding impacts, positive and negative, on destinations. Yet, the mere reproduction of growth rates and passenger numbers in isolation may well foster a misconception and even an overstatement of the cruise sector's significance and role within the wider tourism context. Arguably, the historical analysis and the comparative statistics contained in this paper paint a much-needed realistic picture and contribute to a deeper understanding of the sector's current dynamics.
Nature-based experiences in tree houses: guests’ online reviews
Authors: Brochado Ana 
Published: May 2019

Purpose
This study aims to examine nature-based tourists’ experiences in tree houses using user-generated content in Web reviews. The research objectives were to identify the main dimensions of tree house experiences and test whether these dimensions vary according to different traveller-type market segments.

Design/methodology/approach
A sample of 722 Web reviews was analysed using mixed content analysis methods. Leximancer software provided computer-assisted qualitative data analysis that identified the main themes, after which further qualitative analysis identified the key narratives associated with experiences.

Findings
The results reveal that tourists are extremely satisfied with their stays in tree houses. The main themes that encompass the dominant narratives are tree house, Costa Rica, staff, morning, walk, wildlife, rainforest, opportunity to learn, trip, experience and recommendation. The narratives vary according to type of traveller.

Originality/value
The valuable insights gained emphasise the advantages of using user-generated content in tourism studies. The results also offer a better understanding of the key dimensions of this type of nature-based tourism, including a graphic representation of the main themes and concepts in guests’ narratives. In addition, the findings emphasise that nature-based tourists are not a homogeneous group and that they can be segmented according to type of traveller.
Local authority sustainable planning for tourism: lessons from Ireland
Authors: McLoughlin Emmet , Hanrahan James 
Published: May 2019

Purpose
Sustainability is an essential word in the vocabulary of modern planning; it is the key principle that underpins the Irish planning process. Yet, despite decades of academic and practical debate on sustainable planning and its application to tourism, there still exist many gaps, especially when it comes to its implementation. The purpose of this paper is to highlight, over a 10-year period, how Local Authorities in Ireland have responded to the increasing tourism arrivals, which is having major implications for tourism planning.

Design/methodology/approach
This study used a multi-method approach to determine the level of sustainable planning for tourism as evident from all legally required Local Authority County Development Plans (CDPs) in Ireland.

Findings
While findings have identified a slight increase in the provision for sustainable planning for tourism over the decade, there continues to be poor levels of policy provision in key areas. Despite the responsibilities placed on Local Authorities to sustainably plan for tourism, findings continue to question the ability of Local Authorities in Ireland to plan sustainably for tourism and protect the tourism product.

Originality/value
This research provides the first longitudinal study on the level of sustainable planning for tourism by Local Authorities in Ireland. It provides an assessment of the current state of sustainable planning as evident from CDPs in 2016 compared to the original study of 2006, while developing new knowledge on Local Authority sustainable planning for tourism and the incorporation of tourism indicators.
Oil/fat blending strategy for improving milk fat globule membrane stability and its effect on fatty acid composition
Authors: Ali Fatma , Wang Jianming , Ullah Niamat 
Published: May 2019

This study examined the effect of blending with cumin essential oil (CEO) on the stabilisation of milk fat globule membrane (MFGM) emulsions, as well as the particle migration rate, fatty acid composition and phospholipid content after pasteurisation. Blending the MFGM with 20% CEO at pH 6.6 (CM4) led to a decrease in the creaming rate. With increasing CEO ratio, the creaming measurements increased to a 30 mm height with 20% CEO at pH 5.5 (CM3) from 25 mm with 10% CEO at pH 5.5 (CM2). The CM4 migration rate was 0.55 mm/h, and this sample showed no significant forward movement during implementation. The droplet size increased with increasing CEO ratio from 1.69 to 2.07 µm. A total of 20% CEO at pH 6.6 (CM4) was the best blending condition for MFGM stabilisation. This study showed enhanced creaming rate and droplet size, indicating greater destabilisation of the MFGM emulsion, when the CEO ratio was increased.
How seed defense and seed abundance predict dispersal and survival patterns in Camellia
Authors: XIAO Zhishu , HUANG Xiaoqun 
Published: May 2019

AbstractLittle is known about how seed defense and seed abundance interact with behavioral responses of seed dispersers to predict dispersal and survival dynamics in animal‐dispersed plants. By tracking the fate of individual seeds in Camellia stands with high and low seed abundance in Southwest China in 2007, we investigated the dispersal and survival of 2 high‐saponin Camellia species (Camellia oleifera and Camellia sinensis and 1 non‐saponin species (peanut Arachis hypogaea) as a control. Saponins in Camellia seeds are chemical compounds that act as seed defense. Our results were most consistent with the predictions based on the predator satiation hypothesis and the plant defense hypothesis. At the abundant Camellia stand (predators and dispersers were satiated), more Camellia seeds survived at the source but fewer were hoarded and survived at cache sites. At the sparse Camellia stand (predators and dispersers were not satiated), no Camellia seeds survived at the source, but more Camellia seeds were hoarded and survived at cache sites. Unlike Camellia seeds, no peanuts survived at the source at both stands, while more peanuts were hoarded and then survived at cache sites in the abundant Camellia stand compared to none at the sparse Camellia stand. In addition, the 2 Camellia species showed similar trends for seed fates across different dispersal stages. Our study indicates that the combined effects of seed abundance and seed defense, compared to their separate effects, provide a more accurate prediction for dispersal and survival patterns in animal‐dispersed Camellia species.
Controlling Effects of Tight Reservoir Micropore Structures on Seepage Ability: A Case Study of the Upper Paleozoic of the Eastern Ordos Basin, China
Authors: YANG Bo , QU Hongjun , PU Renhai , TIAN Xiahe , YANG Huan , DONG Wenwu , CHEN Yahui 
Published: May 2019

AbstractIn this study, the types of micropores in a reservoir are analyzed using casting thin section (CTS) observation and scanning electron microscopy (SEM) experiments. The high‐pressure mercury injection (HPMI) and constant‐rate mercury injection (CRMI) experiments are performed to study the micropore structure of the reservoir. Nuclear magnetic resonance (NMR), gas‐water relative seepage, and gas‐water two‐phase displacement studies are performed to examine the seepage ability and parameters of the reservoir, and further analyses are done to confirm the controlling effects of reservoir micropore structures on seepage ability. The experimental results show that Benxi, Taiyuan, Shanxi, and Shihezi formations in the study area are typical ultra‐low porosity and ultra‐low permeability reservoirs. Owing to compaction and later diagenetic transformation, they contain few primary pores. Secondary pores are the main pore types of reservoirs in the study area. Six main types of secondary pores are: intergranular dissolved pores, intragranular dissolved pores, lithic dissolved pores, intercrystalline dissolved pores, micropores, and microfracture. The results show that reservoirs with small pore‐throat radius, medium displacement pressure, and large differences in pore‐throat structures are present in the study area. The four types of micropore structures observed are: lower displacement pressure and fine pores with medium‐fine throats, low displacement pressure and fine micropores with fine throats, medium displacement pressure and micropores with micro‐fine throats, and high displacement pressure and micropores with micro throats. The micropore structure is complex, and the reservoir seepage ability is poor in the study areas. The movable fluid saturation, range of the gas‐water two‐phase seepage zone, and displacement types are the three parameters that well represent the reservoir seepage ability. According to the characteristic parameters of microscopic pore structure and seepage characteristics, the reservoirs in the study area are classified into four types (I–IV), and types I, II, and III are the main types observed. From type I to type IV, the displacement pressure increases, and the movable fluid saturation and gas‐water two‐phase seepage zone decrease, and the displacement type changes from the reticulation‐uniform displacement to dendritic and snake like.
Parsing out the role of dopamine D4 receptor gene (DRD4) on alcohol‐related phenotypes: A meta‐analysis and systematic review
Authors: Daurio Allison M. , Deschaine Sara L. , Modabbernia Amirhossein , Leggio Lorenzo 
Published: May 2019

AbstractGenetics account for moderate variation of individual differences in developing alcohol use disorder (AUD), but it is unclear which genetic variations contribute to AUD risk. One candidate gene investigated due to its association with AUD is the dopamine D4 receptor gene (DRD4), which contains a 48–base pair variable number tandem repeat (VNTR) in exon 3 of its coding region. To date, no quantitative synthesis of the published literature on the effects of DRD4 VNTR variation on alcohol‐related phenotypes has been conducted. MEDLINE, Embase, Web of Science, and PsycInfo were searched for studies that reported on alcohol craving, alcohol consumption, severity of AUD, and case‐control (AUD versus no diagnosis of AUD) studies in DRD4L (seven repeats or more) carriers compared with DRD4S (six repeats or less) homozygotes. Random‐effects meta‐analysis was used for all analyses. A pooled sample size of 655 to 13,360 of 28 studies were included. Compared with DRD4S homozygotes, DRD4L carriers had increased number of drinking days (SMD: 0.205; 95% CI: 0.008 to 0.402), binge drinking days (SMD: 0.217; 95% CI: 0.0532 to 0.380), and severity of AUD (SMD: 0.143; 95% CI: 0.028 to 0.259). There was no difference between DRD4 VNTR genotypes on drinks per drinking day, largest number of drinks per day/occasion, and case‐control analysis. It was not possible to conduct a meta‐analysis of the craving data, but a systematic review of this literature found mixed results on DRD4 VNTR genotype effect. The present meta‐analysis suggests DRD4 VNTR variation may be a risk factor for problematic alcohol use. Our findings are limited, however, by the absence of ancestry data from studies included in our analysis, precluding our ability to adjust for population stratification. Due to the likelihood of type I error in candidate gene approaches, our work highlights the critical need for studies with larger and more inclusive samples that account for sex and genetic ancestry to fully understand this relationship.
Perspectives on successful ageing: The views of Chinese older adults living in Australia on what it means to age well
Authors: Hui Chian Teh Jane , Brown Laura J.E. , Bryant Christina 
Published: May 2019

AbstractObjectivesHigh immigration has resulted in a culturally diverse ageing population. This study aims to examine the meaning of successful ageing among late‐life immigrants ageing in a new cultural environment.MethodsSemi‐structured interviews focused on the subjective experience of ageing well were conducted with 11 Chinese older adults who had moved to Australia in later life. Interviews were conducted in participants’ native language and analysed using thematic analysis.ResultsEleven themes were identified. A collectivist cultural ideal relating to avoiding burden to children underpinned a number of themes, including the importance of good health and financial security. Preferences regarding retaining or relinquishing traditional cultural expectations of dependence on adult children varied between participants, suggesting some postmigration shift in values.ConclusionsThis study provides insights into the nuances of ageing from a novel cultural perspective, and highlights the role of postmigration adaptation in cultural values.

Published: May 2019

BackgroundWhile pelvic floor ultrasound is commonly utilised in high‐resource locations, our understanding of pelvic floor characteristics in women suffering with obstetric fistula and unrepaired fourth degree obstetric tears in low‐resource areas is limited.AimsThis study aimed to assess the pelvic floor ultrasound characteristics of Ugandan women suffering with obstetric fistula, unrepaired fourth degree obstetric tears and pelvic organ prolapse, and determine whether obstructed labour resulting in obstetric fistula causes more levator muscle defects compared to parous women without a history of obstructed labour.Materials and MethodsThis was a prospective study in western Uganda assessing 82 women with obstetric fistula, unrepaired fourth degree obstetric tears and pelvic organ prolapse with a pelvic floor ultrasound scan.ResultsDemographic characteristics were significantly different, with women suffering pelvic organ prolapse being older and more parous. Hiatal area on Valsalva was significantly smaller in the obstetric fistula group (mean 21.45 cm2) compared to non‐obstetric fistula group (unrepaired fourth degree obstetric tears and pelvic organ prolapse; mean 30.44 cm2); a mean difference of 9.0 cm2 (95% CI: 5.4–12.6 cm2, P < 0.001). Overall, levator muscle defects were significantly more common in women with obstetric fistula (66.7%) compared to the non‐obstetric fistula group (44.7%) with P = 0.048; however, there were no significant differences in complete levator muscle defects between obstetric fistula (28.6%) and non‐obstetric fistula (23.7%).ConclusionsIncreased hiatal area on Valsalva was noted in the non‐obstetric fistula group compared to women with obstetric fistula; however, there were no differences in proportions of complete levator muscle defects.
