Digital channels for building collaborative consumption communities
Authors: Garrett Alex , Straker Karla , Wrigley Cara 
Published: April 2017

PurposeCollaborative consumption firms leverage networked peers, communicating, collaborating and even delivering services to one another through a central marketplace channel. This raises questions as to the nature of this new form of digital channel strategy and deployment from a firm’s perspective. As a first step, this research seeks to help bridge the gap in knowledge by establishing an understanding of the digital channel usage of collaborative consumption firms.Design/methodology/approachA qualitative content analysis of 30 collaborative consumption firms was conducted using multiple data sources and coded into typologies against a predetermined coding scheme. These results were then compared against existing literature on digital channel usage in regards to a wider company usage.FindingsThis study identifies the digital channel usage and digital channel typology of each of the 30 firms associated within the collaborative consumption domain. The study shows a distinct increase in the use of social and community digital channels between traditional firms and collaborative consumption firms. As a result of this study, a concise definition of a collaborative consumption firm is provided, the digital channel usage of collaborative consumption firms is detailed and insights are provided for each sub-type of collaborative consumption.Research limitations/implicationsThis study contributes to the understanding of the collaborative consumption phenomena, the business model of collaborative consumption firms and digital channels. This study assists in describing the shift from traditional firms to peer-to-peer systems. Finally, a theoretical model is provided that demonstrates the nuance of collaborative consumption channel choice within each subcategory for future researchers to test and reflect upon.Practical implicationsThis study demonstrates how collaborative consumption firms are allowing customers to drive interaction rather than traditional business-to-customer messages. A theoretical model is provided which shows contemporary marketers how to best dictate a digital channel strategy for a collaborative consumption style initiative.Originality/valueContributions include: a definition of what a collaborative consumption firm and its channels pertain to and how to design a collaborative consumption digital channel strategy. This study presents a digital channel comparison between collaborative consumption firms and traditional organisations.
An indicator of the impact of journals based on the percentage of their highly cited publications
Authors: González-Betancor Sara M. , Dorta-González Pablo 
Published: April 2017

Purpose
The two most used citation impact indicators in the assessment of scientific journals are, nowadays, the impact factor and the h-index. However, both indicators are not field normalized (vary heavily depending on the scientific category). Furthermore, the impact factor is not robust to the presence of articles with a large number of citations, while the h-index depends on the journal size. These limitations are very important when comparing journals of different sizes and categories. The purpose of this paper is to propose an alternative citation impact indicator, based on the percentage of highly cited articles in the journal.

Design/methodology/approach
This alternative indicator is empirically compared with the impact factor and the h-index, considering different time windows and citation percentiles (levels of citation for considering an article as highly cited compared to others in the same year and category). The authors use four journal categories (Clarivate Analytics Web of Science) which are quite different according to the publication profiles and citation levels (Information Science & Library Science, Operations Research & Management Science, Ophthalmology, and Physics Condensed Matter).

Findings
After analyzing 20 different indicators, depending on the citation percentile and the time window in which citations are counted, the indicator that seems to best homogenize the categories is the one that considers a time window of two years and a citation level of 10 percent.

Originality/value
The percentage of highly cited articles in a journal is field normalized (comparable between scientific categories), independent of the journal size and also robust to the presence of articles with a high number of citations.
Innovative silk dyeing using enzyme and Rubia cordifolia extract at room temperature
Authors: Vankar Padma S. , Shukla Dhara , Wijayapala Samudrika , Samanta Asish Kumar 
Published: April 2017

Purpose
Natural dyes are mostly used for dyeing of natural fibre textiles to improve their eco-friendly features. For successful commercial use of natural dyes, the appropriate and standardized dyeing techniques need to be adopted. Appropriate scientific techniques or procedures need to be derived from scientific studies on dyeing methods, dyeing process variables, dyeing kinetics and compatibility of selective natural dyes with minimal use of hazardous chemicals.

Design/methodology/approach
In the present study, different enzymes (protease, amylase, xylanase, pectinase, phytase) were used efficiently with Rubia dye by using simultaneous and two-step processes; both the processes were developed with an aim for conservation of time and energy, for the ease of industrial use. The highlights of the study are twofold: eco-friendly natural dyeing by using enzyme replacing metal mordant and room temperature dyeing, which is a completely new concept.

Findings
Experiments showed that enzymatic treatment can give good colour strength to silk fabric using Rubia as a dye source and has good potential for commercial dyeing. It is a non-toxic dye. Use of enzymes were a deliberate attempt to avoid metal mordanting in silk dyeing, as it would make textile dyeing eco-friendlier. The order of reactivity of enzymes in one-step process was found to be protease > phytase > xylanase > amylase > pectinase. Similarly, for two-step dyeing process, the order of reactivity of enzymes observed was protease > amylase > xylanase = pectinase > phytase. Protease enzyme was the best option in both the cases. Overall, it can be concluded that in the case of enzymatic treatment, the two-step process was better in terms of larger K/S values, colour coordinate values and dye adherence.

Research limitations/implications
A new domain of room temperature dyeing technique has been introduced.

Originality/value
In the present study, different enzymes (protease, amylase, xylanase, pectinase, phytase) were used efficiently with Rubia dye by using simultaneous and two-step processes; both the processes were developed with an aim for conservation of time and energy, for the ease of industrial use. The highlights of the research are twofold: eco-friendly natural dyeing by using enzyme replacing metal mordant and room temperature dyeing, which is a completely new concept. Overall, the ease of use for industrial application. Rubia dye from Sri Lanka has been used in conjunction with different enzymes to show that metal mordanting can be easily replaced by the use of eco-friendly and biodegradable enzymes. The most attractive feature of this study is the low-temperature dyeing at 30-40°C. For any dyeing house, this process can be easily adapted on jigger, winch or even in continuous padding machine. Good fastness properties and dye adherence have been the other highlights of this study.

Published: April 2017

Purpose
The purpose of this paper is to link customer satisfaction, switching intentions, perceived switching costs, and perceived alternative attractiveness in the context of the Bangladeshi mobile telecommunications market (MTM). In addition, this study develops three key formative determinants of customer satisfaction: financial factor, technological factor, and customer service factor.

Design/methodology/approach
A model is developed and tested using PLS-SEM with a sample size of 442 respondents. The three key formative determinants of customer satisfaction were developed using a panel of five industry experts.

Findings
Financial, technological, and customer service factors were found to have significant positive effects on customer satisfaction. Customer satisfaction and perceived switching costs were found to have a significant direct effect on switching intentions, and perceived switching costs and perceived alternative attractiveness were found to have significant moderating effects on switching intentions through customer satisfaction. However, no significant direct effect of perceived alternative attractiveness on switching intentions was found.

Originality/value
This is the first study to link customer satisfaction, switching intentions, perceived switching costs, and perceived alternative attractiveness using structural equation modeling in the context of the Bangladeshi MTM. In addition, three key formative determinants of customer satisfaction are developed.

A trap of optimizing skills use when allocating human resources to a multiple projects environment
Authors: Leite Marco , Baptista António J. , Ribeiro António M.R. 
Published: April 2017

Purpose
The purpose of this paper is to highlight possible hidden risks when allocating multi-skilled human resources to teams working in a multi-project environment. Are allocation strategies maximizing the use of skills for each project, the only way to improve the chances of all projects being successful? What are the risks in this strategy? What are the available alternatives?

Design/methodology/approach
Simulation was used for different allocation strategies to evaluate, using two different metrics, the staffing of human resources in different projects. Three categories of companies were studied, and for each typology, virtual companies were created and several scenarios of collaborators, projects and tasks were simulated to evaluate the staffing process.

Findings
It is shown that for different simulations, different allocation strategies and metrics are possible for evaluation and that there is no golden rule of staffing in organizations with multiple projects and with multiple skills collaborators. The staffing is very much dependent on the context of the company.

Practical implications
The numerical method provides general managers with a useful tool to enable a better distribution of staff collaborators in teams handling multiple projects that require multi-skilled human resources. This method can also be used to evaluate training needs and hiring strategies, as it presents an overview of all human resources skills and motivations.

Originality/value
For academics, the methodology developed enables the study of characteristics of human resources, skills and motivations, which are interesting for team formation. To practitioners, the numerical method is a practical tool for staffing in multiple skills and multiple projects. This tool can also diagnose each company situation regarding current collaborators’ skills and motivations, serving as a tool for training and for hiring.

AbstractA 70‐year‐old woman was diagnosed with a malignant melanoma of the occipital skin which was resected; however, multiple lung metastases were detected. Nivolumab therapy was initiated and partial response was obtained. However, the patient was diagnosed with grade 2 interstitial pneumonitis. Prednisolone administration was initiated and the interstitial pneumonitis shadow disappeared. However, then a right rib metastasis was noticed and given radiation therapy. After progressive disease was obtained, the metastatic lesion was resected, and no relapse occurred until skeletal muscle metastasis was found. According to whole‐exome sequencing and gene expression profiling, the rib and skeletal muscle metastatic lesions showed an upregulated expression of programmed death‐ligand 1 mRNA and a high single‐nucleotide variant (SNV) number. The current melanoma case is representative of a patient who responded to nivolumab therapy, and showed typical immunological markers for responders such as high PD‐L1 expression and high SNV.
Managing trap‐nesting bees as crop pollinators: Spatiotemporal effects of floral resources and antagonists

Published: April 2017

Abstract

The decline of managed honeybees and the rapid expansion of mass‐flowering crops increase the risk of pollination limitation in crops and raise questions about novel management approaches for wild pollinators in agroecosystems. Adding artificial nesting sites, such as trap nests, can promote cavity‐nesting bees in agroecosystems, but effectiveness could be limited by the availability of floral resources in the surrounding landscape and by natural antagonists.

In two European regions, we exposed artificial trap nests in paired field boundaries adjacent to oilseed rape (OSR) fields or non‐flowering crops for 2 years within 32 landscapes covering two independent gradients of OSR cover and semi‐natural habitat (SNH) cover in the landscape. We analysed the effects of local and landscape‐wide floral resource availability, land‐use intensity, landscape complexity and natural antagonists on community composition and population dynamics of trap‐nesting bees.

Numbers of brood cells showed a strong, three‐fold increase in response to the additional nesting sites. Species richness and abundance of cavity‐nesting bees that were active during OSR flowering increased significantly with increasing amounts of early season landscape‐wide floral resource availability, such as the cultivation of OSR. Later foraging species benefited instead from the availability of late‐season alternative flower resources or SNH cover once the mass‐flowering had ceased. Density‐dependent parasitism increased following mass‐flowering, while no density‐dependent effect was found during mass‐flowering.

Structural equation modelling revealed that the influence of floral resource availability on community growth rate was mediated by community size. Community size showed a strong negative effect on community growth rate. Despite positive density‐dependent parasitism, antagonists had only weak regulating effects on community growth rate.

Synthesis and applications. Trap‐nesting bee populations grow markedly with the increasing availability of food resources in the landscape and effectiveness of trap nests is only marginally limited by natural antagonists. Thus, trap nests could be a simple pollinator‐supporting strategy to accompany the current expansion of mass‐flowering crops and to ensure pollination services for insect‐pollinated crops. Trap nests benefit, not only early season active generalist bees during oilseed rape flowering, but also species with later phenology if accompanied by other pollinator‐supporting practices.
Enhanced ecosystem functioning following stream restoration: The roles of habitat heterogeneity and invertebrate species traits
Authors: Frainer André , Polvi Lina E. , Jansson Roland , McKie Brendan G. 
Published: April 2017

Abstract

Habitat restoration is increasingly undertaken in degraded streams and rivers to help improve biodiversity and ecosystem functioning. Follow‐up assessments focused on outcomes for biodiversity have often found scant evidence for recovery, raising concerns about the efficacy of habitat restoration for improving ecological integrity. However, responses of other ecological variables, such as ecosystem process rates and the functional trait composition of biological assemblages, have been little evaluated.

We assessed how the restoration of habitat heterogeneity affected multiple functional parameters in 20 boreal stream reaches encompassing both more and less extensively restored sites, as well as channelised and natural reference sites. We further assessed relationships between our functional parameters and a fluvial geomorphic measure of habitat heterogeneity.

Leaf decomposition was positively related to habitat heterogeneity. This was associated with shifts in the functional composition of detritivore assemblages, with the most obligate litter consumers more prominent in reaches showing higher habitat heterogeneity. The deposition of fine particulate organic matter was consistently higher in restored than channelised sites, and was positively related to the heterogeneity gradient. Algal biomass accrual per unit area did not vary either with restoration or the heterogeneity gradient.

Synthesis and applications. Our findings demonstrate that restoration of river habitat heterogeneity can enhance retention and decomposition of organic matter, key ecosystem properties underpinning ecosystem functioning and service delivery. Significantly, enhanced litter decomposition was linked with a change in the functional composition rather than diversity of detritivore assemblages. Future evaluation of the success of habitat restorations should incorporate quantification of ecosystem processes and the functional traits of biota, in addition to measures of fluvial geomorphology and more traditional biotic metrics, to facilitate a more comprehensive and mechanistic assessment of ecological responses.

AbstractAlbumin leakage during hemodialysis (HD) presents a clinical dilemma. However, protein‐binding uremic toxins are suggested to be responsible for increased mortality. No one has investigated the relationship between albumin leakage and mortality. Therefore, the purpose of this observational study was to analyze the association of albumin leakage with mortality in 690 HD patients who survived one year after enrollment. They were divided to three groups who received HD with large (3 g or more per HD session), middle (1 to 3 g) or small (less than 1 g) amount of albumin leakage, respectively. A propensity score analysis minimizing indication bias was performed. Consequently, in a 7‐year observation period, 212 patients died. Albumin leakage 3 g or more per HD session provided better prognosis than albumin leakage less than 3 g per HD session. In conclusion, clinically acceptable large albumin leakage provides beneficial effects on mortality in maintenance HD patients.

Published: April 2017

Background and ObjectivesYoung adults might engage in many risk behaviors, including alcohol and drug use, which could lead to mental health problems, such as suicide. The aim of this study was to examine specific psychosocial and clinical factors that could influence the possible relationship between polysubstance use (PSU) and suicide risk in a sample of young Colombian participants.MethodsA sample of 274 young participants (mean age = 21.3 years) was evaluated with two substance use screening tests (ASSIST and AUDIT) and five scales for clinical and psychosocial factors and suicide risk: The Center for Epidemiologic Studies Depression scale, Zung Self‐Rating Anxiety scale, Family APGAR, the Childhood Trauma Questionnaire, and the Plutchik Suicide Risk scale. Correlation and multiple regression analyses were conducted.ResultsUse of cannabis and tobacco was significantly correlated with suicide risk in the total sample (p < .05). Depressive and anxiety symptoms, family functioning, and emotional abuse during childhood were significantly associated with suicide risk (p < .001), while alcohol use, anxiety symptoms, and family functioning were variables significantly related to PSU.Discussion and ConclusionsOur findings are consistent with previous evidence suggesting a relationship between substance use, several psychosocial factors, and suicide risk in young participants.Scientific SignificanceOur study is one of the first reports the relationship between substance use and suicide risk in a Latin American population.

Published: April 2017

Background and ObjectivesDepression is common among persons with opioid use disorder. We examined the perceived need for depression treatment (PNDT) among opioid‐dependent patients and the relationship of PNDT to depression screening result.MethodsBetween May and December 2015, we surveyed consecutive persons (n = 440) seeking inpatient opioid detoxification. We used the Patient Health Questionnaire‐2 (PHQ‐2) to screen for depression. To assess perceived need for depression services, participants were asked, “Do you believe you should be treated for depression?” Response options were recorded into four categories: “Not Depressed (ND),” “Perceive Need for Depression Treatment (PNDT),” “Depressed/Don't Want Treatment,” and “Currently Treated.”ResultsParticipants’ mean age was 32.3 (±8.7) years; 70.7% were male. Nearly two out of three persons screened positive for depression yet only 8.2% were being treated for depression prior to admission. Screening positive for depression was associated with a 2.95 (95%CI 1.82–4.81, p < .005) fold increase in the expected odds of PNDT. But nearly half of those depressed (48%) did not perceive the need for treatment. Approximately 40% of the participants (n = 177) perceived that they were not depressed; of these persons, 52% screened positive for depression.Discussion and ConclusionsDetoxification program staff should screen patients for depression, and if a clinical diagnosis is confirmed, discuss treatment options, exploring the level of interest in mental health treatment for depression.Scientific SignificanceScreening for and addressing depression, including patients’ interest in treatment, should be central to post‐detoxification aftercare planning.
