The synergistic activity of eravacycline in combination with colistin on carbapenem-resistant A.baumannii (CRAB) isolates was evaluated in this study. Minimum inhibitory concentrations (MICs) of eravacycline and colistin were determined by the broth microdilution method. MICs values ranged between 1 to 4 mg and 0,5 to 128 mg/L for eravacycline and colistin, respectively. In-vitro synergy between eravacycline and colistin was evaluated by using the chequerboard methodology. Synergistic activity was found in 10 % of the strains, and additive effect in 20 %. No antagonism was detected. Similar activity was also observed in colistin resistant CRAB isolates. The result of this study indicates that eravacycline and colistin combination may be a potential therapeutic option for the treatment of CRAB related infections.

Human land use threatens global biodiversity and compromises multiple ecosystem functions critical to food production. Whether crop yield-related ecosystem services can be maintained by few abundant species or rely on high richness remains unclear. Using a global database from 89 crop systems, we partition the relative importance of abundance and species richness for pollination, biological pest control and final yields in the context of on-going land-use change. Pollinator and enemy richness directly supported ecosystem services independent of abundance. Up to 50% of the negative effects of landscape simplification on ecosystem services was due to richness losses of service-providing organisms, with negative consequences for crop yields. Maintaining the biodiversity of ecosystem service providers is therefore vital to sustain the flow of key agroecosystem benefits to society.

Published: February 2019

MINFLUX offers a breakthrough in single molecule localization precision, but suffers from a tiny field-of-view and a lack of practical parallelism. Here, we combine centroid estimation and illumination pattern induced photon count variations in a conventional widefield imaging setup to extract position information over a typical micron sized field-of-view. We show a near twofold improvement in precision over standard localization with the same photon count on DNA-origami nano-structures.
Specific inhibition of DPY30 activity by ASH2L-derived peptides suppresses blood cancer cell growth
Authors: Shah Kushani , Whitaker Robert H , Busby Theodore , Hu Jing , Shi Bi , Wang Zhenjia , Zang Chongzhi , Placzek William J , Jiang Hao
Published: February 2019

DPY30 facilitates H3K4 methylation by directly binding to ASH2L in the SET1/MLL complexes and plays an important role in hematologic malignancies. However, the domain on DPY30 that regulates cancer growth is not evident, and the potential of pharmacologically targeting this chromatin modulator to inhibit cancer has not been explored. Here we have developed a peptide-based strategy to specifically target DPY30 activity. We have designed cell-penetrating peptides derived from ASH2L that can either bind to DPY30 or show defective or enhanced binding to DPY30. The DPY30-binding peptides specifically inhibit its activity in interacting with ASH2L and enhancing H3K4 methylation. Treatment with the DPY30-binding peptides significantly inhibited the growth of MLL-rearranged leukemia and other MYC-dependent hematologic cancer cells. We also revealed subsets of genes that may mediate the effect of the peptides on cancer cell growth, and showed that the DPY30-binding peptide sensitized leukemia to other types of epigenetic inhibitors. These results strongly support a critical role of the ASH2L-binding groove of DPY30 in promoting blood cancers, and demonstrate a proof-of-principle for the feasibility of pharmacologically targeting the ASH2L-binding groove of DPY30 for potential cancer inhibition.
Classification of visual cortex plasticity phenotypes following treatment for amblyopia
Authors: Balsor Justin L. , Jones David G. , Murphy Kathryn M.
Published: February 2019

Monocular deprivation (MD) during the critical period (CP) has enduring effects on visual acuity and the functioning of the visual cortex (V1). This experience-dependent plasticity has become a model for studying the mechanisms, especially glutamatergic and GABAergic receptors, that regulate amblyopia. Less is known, however, about treatment-induced changes to those receptors and if those changes differentiate treatments that support the recovery of acuity versus persistent acuity deficits. Here we use an animal model to explore the effects of 3 visual treatments started during the CP (n=24, 10 male and 14 female); binocular vision (BV) that promotes good acuity versus reverse occlusion (RO) and binocular deprivation (BD) that causes persistent acuity deficits. We measured recovery of a collection of glutamatergic and GABAergic receptor subunits in V1 and modeled recovery of kinetics for NMDAR and GABAAR. There was a complex pattern of protein changes that prompted us to develop an unbiased data-driven approach for these high-dimensional data analyses to identify plasticity features and construct plasticity phenotypes. Cluster analysis of the plasticity phenotypes suggests that BV supports adaptive plasticity while RO and BD promote a maladaptive pattern. The RO plasticity phenotype appeared more similar to adults with high expression of GluA2 and the BD phenotypes were dominated by GABAAα1, highlighting that multiple plasticity phenotypes can underlie persistent poor acuity. After 2-4 days of BV the plasticity phenotypes resembled normals, but only one feature, the GluN2A:GluA2 balance, returned to normal levels. Perhaps, balancing Hebbian (GluN2A) and homeostatic (GluA2) mechanisms is necessary for the recovery of vision.
MISTERMINATE Mechanistically Links Mitochondrial Dysfunction with Proteostasis Failure

Published: February 2019

Mitochondrial dysfunction and proteostasis failure frequently coexist as hallmarks of neurodegenerative disease. How these pathologies are related is not well understood. Here we describe a phenomenon termed MISTERMINATE (mitochondrial stress-induced translational termination impairment and protein carboxyl terminal extension), which mechanistically links mitochondrial dysfunction with proteostasis failure. We show that mitochondrial dysfunction impairs translational termination of nuclear-encoded mitochondrial mRNAs including complex-I 30kD subunit (C-I30) mRNA, occurring on mitochondrial surface in Drosophila and mammalian cells. Ribosomes stalled at the normal stop codon continue to add to the C-terminus of C-I30 certain amino acids non-coded by mRNA template. C-terminally-extended C-I30 is toxic when assembled into C-I and forms aggregates in the cytosol. Enhancing co-translational quality control prevents C-I30 C-terminal extension and rescues mitochondrial and neuromuscular degeneration in a Parkinson’s disease model. These findings emphasize the importance of efficient translation termination and reveal unexpected link between mitochondrial health and proteome homeostasis mediated by MISTERMINATE.

Published: February 2019

Bacillus velezensis JT3-1 is a probiotic strain isolated from feces of the domestic yak (Bos grunniens) in the Gansu province of China. It has strong antagonistic activity against Listeria monocytogenes, Staphylococcus aureus, Escherichia coli, Salmonella Typhimurium, Mannheimia haemolytica, Staphylococcus hominis, Clostridium perfringens, and Mycoplasma bovis. These properties have made the JT3-1 strain the focus of commercial interest. In this study, we describe the complete genome sequence of JT3-1, with a genome size of 3,929,799 bp, 3761 encoded genes and an average GC content of 46.50%. Whole genome sequencing of Bacillus velezensis JT3-1 will lay a good foundation for elucidation of the mechanisms of its antimicrobial activity, and for its future application.

Viral genetic tools to target specific brain cell types in humans and non-genetic model organisms will transform basic neuroscience and targeted gene therapy. Here we used comparative epigenetics to identify thousands of human neuronal subclass-specific putative enhancers to regulate viral tools, and 34% of these were conserved in mouse. We established an AAV platform to evaluate cellular specificity of functional enhancers by multiplexed fluorescent in situ hybridization (FISH) and single cell RNA sequencing. Initial testing in mouse neocortex yields a functional enhancer discovery success rate of over 30%. We identify enhancers with specificity for excitatory and inhibitory classes and subclasses including PVALB, LAMP5, and VIP/LAMP5 cells, some of which maintain specificityin vivoorex vivoin monkey and human neocortex. Finally, functional enhancers can be proximal or distal to cellular marker genes, conserved or divergent across species, and could yield brain-wide specificity greater than the most selective marker genes.
Self-advocacy and self-determination of autistic students: a review of the literature
Authors: Zuber William James , Webber Colin
Published: February 2019

Purpose

The purpose of this paper is to examine current research on self-advocacy and self-determination of autistic students in order to provide an overview of the research and to critically evaluate researcher’s methods of inclusivity of autistic people. Additionally, this paper will critically analyse the discourse of the current research to assess the extent of deficit, stigma and pathology discourse.

Design/methodology/approach

Research will be selected from a list of criteria which is to seek research that is inclusive of autistic people. The research will be analysed using elements of critical discourse analysis, critical disability studies and critical autism studies. The critical autism studies approach used in this paper is emancipatory to promote autistic scholarship, autistic inclusivity and autistic led research methods.

Findings

The result of this paper is that by prioritising, and including autistic individuals in the studies about them provides valuable educational insights and often challenges assumptions, stigmas and stereotypes of autistic individuals.

Research limitations/implications

The findings of the paper may be limited by the selection of literature reviewed and generalizability, therefore, researchers are encouraged to explore further.

Practical implications

This paper holds potential implications that question the consistency of current discourse and research into self-advocacy for autistic individuals in addition to providing effective research, teaching and support strategies based on insight. This paper also highlights some research that challenges assumptions of autistic individuals.

Social implications

This paper challenges assumptions and stigmas associated with autistic individuals and demonstrates the importance of self-advocacy and self-determination. This research transforms the paradigm of autism and education practice that has the potential to improve autistic individuals’ education and ultimately, improve their lives.

Originality/value

This research is important and valuable as there is limited research in this area. The potential of this research is that it can shift the broad perceptions of autism and make improvements in education and autistic individuals lives.
Prosocial process fit: normatively expected purchasing increases the prosocial premium
Authors: Mathmann Frank , Pohlmeyer Lisa , Higgins E. Tory , Weeks Clinton
Published: February 2019

Purpose

This paper aims to investigates the effect of normative expectations in the purchase process on consumers’ value perceptions for prosocial products (e.g. environmentally friendly products) relative to conventional non-prosocial products. It extends the literature on both prosocial products and regulatory fit.

Design/methodology/approach

Five factorial experiments are employed, testing diverse samples, including Dutch university students and American online panel participants from the general population.

Findings

Findings show that regulatory fit between the prosocial product orientation and an emphasis on normative expectations in the purchase process (termed prosocial process fit) increases perceptions of prosocial product value (relative to conventional products). This effect is mediated by engagement.

Research limitations/implications

The current research is limited to investigating how value perceptions of prosocial products can be increased (i.e. through prosocial process fit). Future research is warranted that analogously considers conditions that would increase value for non-prosocial products as well (e.g. by creating a fit with a non-prosocial process).

Practical implications

The research shows how prosocial manufacturers and retailers can redesign the purchase process to increase customers’ engagement, perceptions of prosocial product value and prosocial product purchase.

Social implications

This work serves to explain differences in consumers’ value perceptions for prosocial products. Hence, it shows how socially responsible consumption can be better supported in society.

Originality/value

This work demonstrates a new kind of regulatory fit based on fit between prosocial products and normative expectations in the purchase process (i.e. moving beyond the types of regulatory fit previously examined in this context, such as with fit between regulatory focus orientation and goal pursuit). The authors use this to provide a much needed explanation for the heterogeneity in the literature regarding the value that consumers experience for prosocial products relative to conventional ones.
Investigating the role of customers’ perceptions of employee effort and justice in service recovery
Authors: Yani-de-Soriano Mirella , Hanel Paul H.P. , Vazquez-Carrasco Rosario , Cambra-Fierro Jesús , Wilson Alan , Centeno Edgar
Published: February 2019

Purpose

The purpose of this paper is, first, to identify the relationship, if any, between customers’ perceptions of justice (functional element) and employee effort (symbolic element) and their effects on satisfaction and loyalty in the context of service recovery and, second, to determine the impact of cross-cultural differences on these relationships.

Design/methodology/approach

Survey data from actual customers were gathered in three countries ( n = 414) and analyzed using structural equation modeling to test the proposed hypotheses.

Findings

The results demonstrate the role of the constructs of perceived employee effort and perceived justice in influencing post-recovery satisfaction and loyalty across cultures. While perceived justice is valued across cultures, customers from feminine (masculine) cultures require more (less) employee effort to influence post-recovery satisfaction positively. Customers from low (high) uncertainty cultures are more (less) willing to give the provider another chance after a service recovery.

Research limitations/implications

The study shows that both functional and symbolic elements of service recovery are important determinants of customer satisfaction and loyalty and that their influence can be significant in a cross-cultural context.

Practical implications

International service managers must consider the nature of cultural differences in their markets to develop and implement tailored recovery strategies that can result in satisfied customers.

Originality/value

This study is the first to integrate the functional and symbolic elements of service recovery, their impact on customers’ behavioral responses and the influence of cultural variations.
The effect of music tempo on consumer impatience in intertemporal decisions
Authors: Kim Kyu , Zauberman Gal
Published: February 2019

Purpose

This paper aims to examine the effect of music tempo on impatience in intertemporal tradeoff decisions. It finds that fast (vs slow) tempo music increases impatience. This occurs because fast (vs slow) tempo music makes temporal distance, and hence the waiting time until the receipt of delayed benefits, feel subjectively longer.

Design/methodology/approach

The study tests the hypotheses through four laboratory experiments.

Findings

In Studies 1a (N = 88) and 1b (N = 98), the results demonstrate that when participants listen to fast (vs slow) tempo music, they judge temporal distance to be longer. In Study 2 (N = 94), the results demonstrate that when participants listen to fast (vs slow) tempo music, they become more impatient when considering a smartphone purchase. In Study 3 (N = 218), the results demonstrate that when participants listen to fast (vs slow) tempo music, they become more impatient when considering a gift certificate, and that this delay discounting effect is attributable to the change in their temporal distance judgment.

Research limitations/implications

The current research reports a novel factor that influences impatience in intertemporal decisions and temporal distance judgment.

Practical implications

This research provides useful guidelines for retail managers and marketers regarding the effect of background music in stores.

Originality/value

This is the first study demonstrating a music tempo effect on temporal distance judgment and impatience in intertemporal tradeoff decisions.
Co-constructing loyalty in an era of digital music fandom
Authors: Obiegbu Chinedu James , Larsen Gretchen , Ellis Nick , O’Reilly Daragh
Published: February 2019

Purpose

This paper aims to answer the following question: How can a discursive approach to how music fans construct loyalty in a digital context contribute to a theoretical understanding of brand loyalty?

Design/methodology/approach

Drawing on insights from theories of brand loyalty and fandom, this interpretive inquiry makes use of data from an online forum dedicated to the rock music band, U2, and interviews with forum members. A combination of online ethnography and discourse analysis are used.

Findings

The analysis shows that music fans mobilise particular discursive resources in constructing loyalty in the digital context, specifically length of time spent as a fan, obsession and the opposition of obligation and choice. These discursive resources reflect a grounded account of an experientially rooted brand loyalty that extends beyond attitudinal and behavioural loyalty and which is particularly salient in music consumption.

Research limitations/implications

This is a single case study, but as a rich and vibrant online community, it provides fruitful insights into the discursive construction of loyalty. The processes of negotiation, accommodation and conflict, engaged in through online discourse, are important in laying bare the preferences, value systems and meanings that frame the experiences of loyal consumers.

Practical implications

This socially constructed view of loyalty facilitates a more sensitive and nuanced application of brand loyalty, with implications for segmentation and targeting activities. It provides a possible basis through which precise insights can be gained into the meanings and practices of loyal fans and consumers.

Originality/value

Examining loyalty through the lens of online music fandom enables a discursive understanding of consumers’ experience of brand loyalty. It shows how online engagement with other consumers of a brand facilitates a deep engagement with the notion of loyalty.
Experiencing nostalgia through the lens of life satisfaction
Authors: Khoshghadam Leila , Kordrostami Elika , Liu-Thompkins Yuping
Published: February 2019

Purpose

This paper aims to examine the role of life satisfaction in consumers’ reaction to nostalgic music in an advertisement in terms of attitude toward the brand and purchase intention. It suggests that life satisfaction forms the lens through which individuals interpret and reconstruct past emotional experiences evoked by nostalgia. It further investigates the role of product category involvement in the interplay between life satisfaction and nostalgic music.

Design/methodology/approach

Two experiments were conducted. The first study featured a 2 (nostalgic vs non-nostalgic music) × 2 (high vs low involvement) between-subjects design and tested the research hypotheses with 208 consumers. The second study featured two involvement conditions (high vs low) and explored the underlying process behind the hypotheses. Linear regression was used to analyze the data in both studies.

Findings

For the low involvement product category, nostalgic music was more effective than non-nostalgic music for consumers with high life satisfaction, whereas non-nostalgic music was more effective for consumers with low life satisfaction levels. For the high involvement product category, life satisfaction did not moderate consumers’ reaction to nostalgic music.

Research limitations/implications

This research suggests that past experiences evoked through nostalgic music are not static but are subject to bias and interpretation depending on an individual’s current mindset. Hence, the eventual effect of nostalgia is determined by how past events are reconstrued based on the individual’s current state.

Practical implications

This paper warns against the blind use of nostalgic appeals in advertising, points to the need to consider the audience’s state of mind, and suggests an opportunity to leverage life satisfaction influencers in designing effective advertising campaigns.

Social implications

The findings have strong implications for public policymakers. The results are crucial as policymakers often use public service announcement (PSA) to change the attitude of the public toward some phenomena. Knowing the current state of life satisfaction in society, they can increase the efficiency of public service announcements by including a nostalgic song in them.

Originality/value

To the best of the authors’ knowledge, this research is the first one in the marketing literature that looks at the efficiency of nostalgic songs in advertisements. The authors tested the conceptual framework by using two studies and offered novel implications to both marketers and scholars.
Internship and employability prospects: assessing student’s work readiness
Authors: Kapareliotis Ilias , Voutsina Katerina , Patsiotis Athanasios
Published: February 2019

Purpose

Changes in the workplace have raised serious concerns about the future of work and the effectiveness of undergraduate academic programs to sufficiently prepare students for business. The purpose of this paper is to address this concern by exploring how internship employment (placement) is implicated in the young business graduates’ employability prospects.

Design/methodology/approach

This research explored the students’ perceptions regarding their degree of “work readiness” after completing an internship program. The concept of “work readiness” is conceptualized in terms of role clarity, ability and motivation. An institution of higher education in Greece provided the sampling frame for this research. Online survey data have been used.

Findings

Students who attend internship programs assessed positively all aspects of the work readiness construct. They knew what it was expected by employers from them to do at work. They were able to effectively apply basic academic skills, high-order skills and professional skills required by employers on the job and placed greater importance to the intrinsic rewards than the extrinsic ones.

Research limitations/implications

This is an exploratory study and is designed as a foundation for future empirical studies. Further research could examine the dimensions of the work readiness concept in other geographic contexts and validate the scale measurement with larger samples.

Originality/value

The integration of scattered pieces of literature on graduates’ employability through the lenses of “work readiness” is a novel theoretical approach to explore the effectiveness of internship programs on employability prospects in the Greek context.
Improving financial literacy in college of business students: modernizing delivery tools
Authors: Kuntze Ronald , Wu Chen (Ken) , Wooldridge Barbara Ross , Whang Yun-Oh
Published: February 2019

Purpose

The purpose of this paper is to develop and test through an experiment, an innovative online video teaching module that significantly improves financial literacy in college of business students. Specific business major financial literacy levels are also tested.

Design/methodology/approach

A total of 244 college of business students were given a financial literacy test. Half of the students were exposed to the “treatment” (watched a video module), while other half were not. The videos comprised 67 min of micro-lectures that students could download, free of charge, at their own convenience. The researchers analyzed the impact of a previous personal finance course on students’ financial literacy levels and tested across four business majors.

Findings

The video intervention was the most successful at increasing financial literacy, surprisingly more so than having taken a past personal finance course. Interaction effects were not significant. Four college majors were tested with a shorter, improved financial literacy measure – finding, to our surprise that non-quantitative business majors (particularly marketing students) are not less financially literate than other majors. Supporting past research, the authors found that female and African-American college students performed significantly lower on the test.

Originality/value

The research adds value to the literature by developing and testing a modern, novel teaching innovation to improve financial literacy in young adults. Using an experimental setting, the authors showed that the innovation was more effective than the commonly proscribed personal finance course. This is one of the few studies to measure financial literacy levels for specific college of business majors.
Consumers’ responses to invitations to write online reviews
Authors: Zhang Lu , Yang Wan
Published: February 2019

Purpose

The main purpose of the current research is to investigate the effectiveness of messages sent out by firms inviting customers to write online reviews. The joint effect of message framing, power and individuals’ need for status (NFS) on consumers’ intentions to write a review was examined.

Design/methodology/approach

This study uses a 2 (message framing: self-vs other-focused) × 2 (power state: high vs low) × 2 (NFS: high vs low) factorial design with message framing being manipulated and power and NFS being measured.

Findings

The results show that customers low in power are more likely to be persuaded by a message focused on others (vs self), and customers high in power show similar levels of behavioral intention regardless of message framing. Furthermore, this effect is significant only among those with a high (vs low) NFS.

Practical implications

Hospitality practitioners may consider customizing the invitation message based on target consumers’ individual traits. They may either prime consumers’ status seeking intentions and/or sense of power, or gain such insights through outside marketing research companies. Depending on the characteristics of the recipients, companies can choose either a self-focused or an other-focused message to increase its persuasiveness.

Originality/value

This is one of the first studies examining the joint effect of message framing, power and NFS on consumers’ willingness to write online reviews.
Mental healthcare interfaces in a regional Irish prison
Authors: Gulati Gautam , Otuokpaikhian Kizito , Crowley Maeve , Pradeep Vishnu , Meagher David , Dunne Colum P.
Published: February 2019

Purpose

The purpose of this paper is to study the demographic, clinical characteristics and outcomes for those prisoners referred to secondary mental healthcare in a regional Irish prison and the proportion of individuals diverted subsequently from prison to psychiatric settings.

Design/methodology/approach

The authors conducted a retrospective review of 130 successive psychiatric assessment case records at a regional mixed gender prison serving six southern Irish counties. The authors analysed demographics, clinical characteristics and outcomes. Where diversion out of prison was undertaken, Dangerousness, Understanding, Recovery and Urgency Manual (DUNDRUM) scores were retrospectively completed to assess security need.

Findings

In total, 8.6 per cent of all committals from liberty were referred by a general practitioner and 8.1 per cent subsequently assessed by the visiting psychiatrist. Predominantly, these were young males charged with a violent offence. In all, 42.2 per cent of those assessed by secondary care were diagnosed with a substance misuse disorder and 21.1 per cent with a personality disorder. In total, 20.3 per cent suffered from a psychotic disorder and 10.6 per cent with an affective disorder. Of those seen by psychiatric services, 51.2 per cent required psychotropic medication, 29.2 per cent required psychological input and 59.3 per cent required addiction counselling. In all, 10.6 per cent of those assessed were diverted from prison, the majority to approved centres. Mean DUNDRUM-1 scores suggested that those referred to high and medium secure hospitals were appropriately placed, whereas those diverted to open wards would have benefited from a low secure/intensive care setting.

Originality/value

The multifaceted need set of those referred strengthens the argument for the provision of multidisciplinary mental healthcare into prisons. The analysis of security needs for those diverted from prisons supports the need for Intensive Care Regional Units in Ireland.
An evaluation of Take Home Naloxone program implementation in British Columbian correctional facilities
Authors: Pearce Lindsay A. , Mathany Lauren , Rothon Diane , Kuo Margot , Buxton Jane A.
Published: February 2019

Purpose

To understand how the Take Home Naloxone (THN) program is implemented in two pilot correctional facilities in British Columbia (BC), Canada, in order to identify areas for program improvement and inform the expansion of the program to other Canadian correctional facilities The paper aims to discuss these issues.

Design/methodology/approach

Two focus groups and one interview were conducted with healthcare staff at two pilot correctional facilities. Sessions were audio recorded, transcribed verbatim and divergent and convergent experiences within and between the facilities were explored in an iterative process. Key themes and lessons learned were identified and later validated by focus group participants.

Findings

Key themes that emerged included: challenges and importance of the train-the-trainer program for healthcare staff conducting participant training sessions; potential for improved prison population engagement and awareness of the program; tailoring program resources to the unique needs of an incarcerated population; challenges connecting participants to community harm reduction resources following release; and clarifying and enhancing the role of correctional officers to support the program.

Research limitations/implications

The correctional setting presents unique challenges and opportunities for the THN program that must be considered for program effectiveness.

Originality/value

This evaluation was conducted to inform program expansion amidst a historic opioid overdose epidemic in BC, and adds to the limited yet growing body of literature on the implementation and evaluation of this program in correctional settings globally.
An exploration of MDT views on key factors to consider when determining a service users required level of security
Authors: Khan Zulaikha , Chidambaram Arun , Thomson Michaela , Hurst Courtney
Published: February 2019

Purpose

The purpose of this paper is to identify what key factors multi-disciplinary teams (MDT) deem as most important when making the decision to move service users from one level of security (including low, medium and high secure services) to another. The researchers used the findings from this study to further develop a tool; the assessment for level of security tool (ALS), which aims to structure and streamline this decision-making process.

Design/methodology/approach

Data from 18 interviews (MDT staff) were analysed using the Delphi technique (Dalkey and Helmer, 1963). This revealed a range of factors discussed when considering service users moves. Participants were asked to rate these factors in accordance with the Delphi which resulted in the removal of certain less important factors based on their scores. The researchers then compared these factors of relevance with a checklist of 16 items previously proposed by a consultant psychiatrist within the trust. This comparison allowed the researchers to highlight any similarities and differences present.

Findings

Findings from staff interviews revealed a range of 20 clinical factors perceived as essential to this process including procedural, relational and physical security aspects. However, variations were evident between the MDT priorities (20 items) and the originally proposed list. This emphasised the need for a tool which facilitates a holistic and streamlined approach.

Practical implications

The findings from this research have resulted in the development of the ALS tool comprising of 18 key factors.

Originality/value

It is envisaged the development of the ALS tool will not only facilitate and structure the decision-making process but also ensure a person-centred approach. This is because the ALS allows for a holistic approach based on an array of factors deemed important to that particular service user. Furthermore, the ALS tool contributes towards the paucity of published structured professional judgement tools needed to make such decisions.
Gig-workers’ motivation: thinking beyond carrots and sticks
Authors: Jabagi Nura , Croteau Anne-Marie , Audebrand Luc K. , Marsan Josianne
Published: February 2019

Purpose

High-quality employee motivation can contribute to an organization’s long-term success by supporting employees’ well-being and performance. Nevertheless, there is a paucity of research concerning how organizations motivate workers in non-traditional work contexts. In the algocratic context of the gig-economy, the purpose of this paper is to understand the role that technology can play in motivating workers.

Design/methodology/approach

Drawing on the self-determination theory, job-characteristic theory and enterprise social media research, this conceptual paper explores how the architecture of the digital labor platforms underlying the gig-economy (and the characteristics of jobs mediated through these IT artifacts) can impact key antecedents of self-motivation.

Findings

Combining theory and empirical evidence, this paper develops a mid-range theory demonstrating how organizations can support the self-motivation of gig-workers through the thoughtful design of their digital labor platforms and the integration of two social media tools (namely, social networking and social badging).

Research limitations/implications

This paper answers calls for psychologically-based research exploring the consequences of gig-work as well as research studying the impacts of advanced technologies in interaction with work contexts on motivation. In theorizing around a large set of social-contextual variables operating at different levels of analysis, this paper demonstrates that individual-level motivation can be influenced by both task-based and organizational-level factors, in addition to individual-level factors.

Originality/value

The proposed theory provides novel insight into how gig-organizations can leverage widely accessible social media technology to motivate platform workers in the absence of human supervision and support. Theoretical and practical implications are discussed.

Purpose

With continuous concerning on the toxic of element Pb, Pb-free solder was gradually used to replace traditional Sn-Pb solder. However, during the transition period from Sn-Pb to Pb-free solder, mixing of Sn-Pb and Pb-free is inevitable occurred in certain products, and in China where Sn-Pb solder was still used extensively in certain areas especially. Correspondingly, understanding reliability of Sn-Pb solder joints was very important, and further studies were needed.

Design/methodology/approach

Thermal shock test between −55°C and 125 °C was conducted on Sn-37Pb solder bumps in the BGA package to investigate the microstructure evolution and the growth mechanism of interfacial intermetallic compound (IMC) layer. The effects of thermal shock on the mechanical property and fracture behavior of Sn-37Pb solder bumps were discussed.

Findings

Pb-rich phase was coarsened and voids were increased at first; Pb-rich phase was refined and voids were decreased secondly with the increase of thermal shock cycles; the shear strength of solder bumps was slightly decreased after thermal shock, but was back up to 73.67MPa at 2,000 cycles; interfacial IMCs of solder bumps was from typical scallop-type into smooth, the composition of IMCs was from Cu6Sn5 into Cu6Sn5 and Cu3Sn after thermal shock with 1,500 and 2,000 cycles; 20.0 per cent of solder bumps at 1,500 cycles and 9.5 per cent of solder bumps at 2,000 cycles were failure respectively.

Originality/value

Compared with the board level test method, the impact shear test for the single solder bump is more convenient and economical and is actively pursued by the industries. The shear strength of solder bumps was slightly decreased after thermal shock, but was back up to 73.67 MPa at 2,000 cycles; 20.0 per cent of solder bumps at 1,500 cycles and 9.5 per cent of solder bumps at 2,000 cycles were failure.

Vertical–vertical controlled‐source electromagnetic is an alternative to other techniques for providing three‐dimensional resistivity images of the subsurface. It utilizes a large and powerful vertical dipole transmitter and arrays of E‐field receivers with vertical and horizontal dipole sensors. The necessary instrumentation and acquisition procedures which differ strongly from other controlled‐source electromagnetic methods are described in the paper.
Routes to achieving sustainable intensification in simulated dairy farms: The importance of production efficiency and complimentary land uses
Authors: White Patrick J. C. , Lee Mark A. , Roberts Dave J. , Cole Lorna J.
Published: February 2019

Sustainable intensification (SI) is a global challenge, aiming to increase food production whilst conserving biodiversity and ecosystem services. This is contrary to the observed trend of agricultural intensification degrading environmental quality. We developed a framework integrating animal nutrition, crop yields and biodiversity modelling to explore SI potential in multiple model dairy farming systems through varying crop composition to provide cattle feed rations. We then identified key drivers of biodiversity gain that may be applicable at a wider scale.

We developed multiple feed rations to meet the nutritional demands of a high‐yielding, housed dairy herd. The land area required varied due to productivity and nutritional differences between crops, generating spare land. We used published biodiversity models to compare alpha‐ and beta‐diversity of spiders and plants across 36 scenarios that used the spare land in different ways, for either biodiversity maximisation or additional production.

Alpha and beta‐diversity for both taxa was the greatest in scenarios that maximised spare land and utilised this for species‐rich extensive grassland. However, commensurate biodiversity gains for plant alpha‐diversity, and spider and plant beta‐diversity (respectively 100%, 76% and 86% gain relative to that optimal scenario) were achievable when spare land was used for additional crop production.

Maximising compositional heterogeneity and adding complementary productive land uses to spared land were key to increasing production and beta diversity, while adding species‐rich productive land uses drove increasing production and alpha diversity.

Synthesis and applications. This study indicates the potential for the sustainable intensification of dairy farming systems through the manipulation of feed rations to increase land efficiency and spare land, which could then be used to enhance production and biodiversity. The optimum land composition depends on target goal(s) (e.g. maximising production and/or biodiversity). The greatest ‘win‐wins’ can be achieved by making land cover more diverse and selecting crops that complement each other in the species they support; highlighting the important role of heterogeneity in the crop matrix. Our study provides a framework that integrates agricultural production efficiency and biodiversity modelling to explore potential routes to achieve sustainable intensification goals.
The politics of interbasin transfers: socio‐environmental impacts and actor strategies in Tunisia
Authors: Ben Fraj Wafa , Elloumi Mohamed , Molle François
Published: February 2019

Mediterranean wetlands are of key interest in the preservation of biodiversity. However, their ecological water requirement is in constant competition with human uses, particularly in a context of aridity and climate change. This paper examines the case of the Ichkeul Lake‐Lagoon system located in the north of Tunisia in a river basin that is heavily contributing to the water supply of southern regions through water transfers. It maps out the various actors involved, their stakes, discourses and strategies, and explains the current degradation of the Ichkeul system by unpacking the decision‐making power of these actors. It confirms that marginal social groups, ecosystems and next generations are the main parties affected by current water allocation patterns.
Review article: Non‐fatal strangulation: Hidden injuries, hidden risks
Authors: De Boos Julia
Published: February 2019

Non‐fatal strangulation (NFS) can be a cause of severe injury. However, the prevalence and rates of injuries from NFS are unknown, as few victims present to medical attention after strangulation. As up to 40% of fatal strangulations have no external signs, and the majority of surviving victims have few or minor injuries, finding those people severely injured remains challenging. The majority of the evidence regarding NFS is largely based on case reports and case series with no robust studies estimating rates of injuries or the best investigation tools. The injuries that are reported make clear that strangulation is a potentially lethal form of injury that should not be ignored in those presenting having been strangled, or in those presenting with neurological symptoms, including strokes, seizures and vascular abnormalities. The safety implications of strangulation are also important as it can be a prelude to homicide. A search of the literature was carried out with the following terms: Nonfatal strangulation (10), Nonfatal strangulation (17), ‘Strangulation injuries’ (19), ‘Manual strangulation’ (92) – laboratory testing eliminated, and ‘choking game’. The PubMed database was used first, followed by the collections of Monash University and the Strangulation Institute (as some articles were too old to find electronically). This article summarises the injuries that can occur following strangulation and discusses the quality of the evidence thus far.
