Deep Salient Object Detection with Contextual Information Guidance.

Integration of multi-level contextual information, such as feature maps and side outputs, is crucial for Convolutional Neural Networks (CNNs) based salient object detection. However, most existing methods either simply concatenate multi-level feature maps or calculate element-wise addition of multi-level side outputs, thus failing to take full advantages of them. In this work, we propose a new strategy for guiding multi-level contextual information integration, where feature maps and side outputs across layers are fully engaged. Specifically, shallower-level feature maps are guided by the deeper-level side outputs to learn more accurate properties of the salient object. In turn, the deeper-level side outputs can be propagated to high-resolution versions with spatial details complemented by means of shallower-level feature maps. Moreover, a group convolution module is proposed with the aim to achieve high-discriminative feature maps, in which the backbone feature maps are divided into a number of groups and then the convolution is applied to the channels of backbone feature maps within each group. Eventually, the group convolution module is incorporated in the guidance module to further promote the guidance role. Experiments on three public benchmark datasets verify the effectiveness and superiority of the proposed method over the state-of-the-art methods.

Real-time decoding of question-and-answer speech dialogue using human cortical activity

Natural communication often occurs in dialogue, differentially engaging auditory and sensorimotor brain regions during listening and speaking. However, previous attempts to decode speech directly from the human brain typically consider listening or speaking tasks in isolation. Here, human participants listened to questions and responded aloud with answers while we used high-density electrocorticography (ECoG) recordings to detect when they heard or said an utterance and to then decode the utterance’s identity. Because certain answers were only plausible responses to certain questions, we could dynamically update the prior probabilities of each answer using the decoded question likelihoods as context. We decode produced and perceived utterances with accuracy rates as high as 61% and 76%, respectively (chance is 7% and 20%). Contextual integration of decoded question likelihoods significantly improves answer decoding. These results demonstrate real-time decoding of speech in an interactive, conversational setting, which has important implications for patients who are unable to communicate.

An innovative method for clinical practice guideline contextualisation for chronic musculoskeletal pain in the South African context

BackgroundClinical guidelines produced in developed nations may not be appropriate in resource-constrained environments, due to differences in cultural, societal, economic and policy contexts. The purpose of this article is to describe an innovative and resource-efficient method to develop a clinical practice guideline (CPG), using the CPG contextualisation approach.MethodsThe four phased contextualisation framework was applied to produce a contextualised, multidisciplinary CPG for the primary health care of adults with chronic musculoskeletal pain (CMSP) in the South African context. The four phases were: a contextual analysis, evidence synthesis, contextual integration and external evaluation. Qualitative methodology was used to investigate context factors influencing health care in this environment. A systematic review was conducted to identify current, high-quality CPGs on the topic, and to synthesise a core set of clinical recommendations from the CPGs. Consensus methods were used to integrate context information with recommendations. A multidisciplinary panel of local experts authenticated and contextualised recommendations. The resultant CPG was externally reviewed using a survey.ResultsThe results from the contextual analysis phase indicated a wide range of contextual factors that could influence the applicability and implementability of the recommendations, including: the personal characteristics of the patient and clinician, social and environmental circumstances, healthcare interventions available, and healthcare system factors. During phase two, six existent high quality CPGs were identified and a core set of multidisciplinary recommendations were sourced from them. The contextual integration phase produced the validated recommendations, accompanied by its underpinning body of evidence and context specific information. The outcome of phase four (external review) was that the recommendations were confirmed as relevant for the intended setting.ConclusionCPG contextualisation was found to be a practical approach to develop a contextualised multidisciplinary CPG for the primary health care of adults with CMSP in a South African setting. The contextualisation approach enhanced the integration of multiple stakeholder perspectives and highlighted the importance of considering clinical, social and economic complexities during CPG development. Attention to contextual information is advocated to enhance the uptake of CPG recommendations, particularly in resource constrained settings.Trial registrationHealth Research Ethics Committee of Stellenbosch University, South Africa (S14/01/018); the review protocol was registered on PROSPERO (registration number CRD42015022098).

Double-checking emotions: Valence and emotion category in contextual integration of facial expressions of emotion

Faces showing happy, angry or fearful expressions were presented in emotionally congruent or incongruent situational contexts (short sentences describing events that would usually provoke happiness, anger or fear). The participants were assigned the task of judging whether the expression was appropriate or not to the context (congruency judgment task). Effects of emotional congruency were observed at both the behavioral and electrophysiological levels. Behavioral results showed evidence of congruency effects based on specific emotion content (e.g., less accurate and slower responses to fear faces in angry contexts). Event-related-potentials (ERP) results also showed emotional congruency effects at different post-stimulus onset latencies, beginning with the face-sensitive N170 component. An effect of emotional congruency was also shown on the N400 component that is typically sensitive to semantic congruency. Finally, a late positive potential (LPP), appearing at 450–650 ms post-stimulus onset showed a complex pattern of effects with modulations driven by the different combinations of contexts and target expressions. These results are interpreted in terms of a double process of valence and emotion checking that is supposed to underlie affective processing and contextual integration of facial expressions of emotions.

Integration of curated and high-throughput screening data to elucidate environmental influences on disease pathways

Addressing the complex relationship between public health and environmental exposure requires multiple types and sources of data. An important source of chemical data derives from high-throughput screening (HTS) efforts, such as the Tox21/ToxCast program, which aim to identify chemical hazard using primarily in vitro assays to probe toxicity. While most of these assays target specific genes, assessing the disease-relevance of these assays remains challenging. Integration with additional data sets may help to resolve these questions by providing broader context for individual assay results. The Comparative Toxicogenomics Database (CTD), a publicly available database that builds networks of chemical, gene, and disease information from manually curated literature sources, offers a promising solution for contextual integration with HTS data. Here, we tested the value of integrating data across Tox21/ToxCast and CTD by linking elements common to both databases (i.e., assays, genes, and chemicals). Using polymarcine and Parkinson’s disease as a case study, we found that their union significantly increased chemical-gene associations and disease-pathway coverage. Integration also enabled new disease associations to be made with HTS assays, expanding coverage of chemical-gene data associated with diseases. We demonstrate how integration enables development of predictive adverse outcome pathways using 4-nonylphenol, branched as an example. Thus, we demonstrate enhancements to each data source through database integration, including scenarios where HTS data can efficiently probe chemical space that may be understudied in the literature, as well as how CTD can add biological context to those results.

„A little Drama“ (G. M. Tucker)

Abstract The use of a narrative imperfect in Am 7:10–17 after 7:1–9 and the abrupt shift to 8:1–3 frequently compelled critics to determine its literary form. For diachronic studies defining classifications include ‘third-party report’ and ‘apophthegma’. By contrast, synchronic studies emphasize the contextual integration of Am 7:10–17 and concentrate on a narrative analysis. Within this focus it is striking, that the passage is often associated with a ‘drama’ but without assessing the methodological ramifications of such a claim. The present article takes this ‘synchronic gap’ up and relates it to approaches to view drama as a possible genre for prophetic books. In doing so, a reading of Am 7:10–17 as part of a narrator-mediated discourse using a dramatic mode shows that the passage can be deemed an entrance with three speeches integrated into the wider context of 7:1–8:3. Particularly the classification of 7:10a, 12aα, 14aα as narrator’s discourse using a dramatic mode makes this claim plausible.

The congruent, the incongruent, and the unexpected: Event-related potentials unveil the processes involved in schematic encoding

Learning is most effective when new information can be related to a preexisting knowledge structure or schema. In the present study, event-related potentials (ERPs) were used to investigate the temporal dynamics of the processes by which activated schemata support the encoding of schema-congruent information. Participants learned category exemplar words that were either semantically congruent or incongruent with a preceding category cue phrase. Congruent words were composed of expected (high typicality, HT) and unexpected (low typicality, LT) category exemplars. On the next day, recognition memory for the exemplars and the category cues they were presented with was tested. Semantically related lures were used in order to ascertain that memory judgements were based on episodic memory for specific category exemplars. Generally, congruent (HT and LT) exemplars were remembered better than incongruent exemplars. ERPs recorded during the encoding of the exemplar words were compared for subsequently remembered and forgotten items. Subsequent memory effects (SME) emerged in the N400 time window at frontal electrodes and did not differ between congruent and incongruent exemplars. In the same epoch, an SME with a parietal distribution was specific for congruent exemplars, suggesting that activated schemata strengthened memory for congruent exemplars by supporting the encoding of item-specific details. Subsequently remembered LT exemplars were associated with a late frontal positivity that is assumed to reflect expectancy mismatch-related processing such as the contextual integration of an unexpected word by the suppression of strongly expected words. A correlation analysis revealed that the greater the involvement of the processes reflected by the frontal positivity, the lower the level of false positive memory responses in the test phase one day later. These results suggest that the contextual integration of schema-congruent but unexpected events involves a weakening of the representations of semantically related, but unstudied items in memory and by this benefits subsequent memory.

Innate colour preferences of a hawkmoth depend on visual context.

Solitary insects that feed on floral nectar must use innate knowledge to find their first flower. While innate preferences for flower colours are often described as fixed, species-specific traits, the nature and persistence of these preferences have been debated, particularly in relation to ontogenetic processes such as learning. Here we present evidence for a strong context-dependence of innate colour preferences in the crepuscular hawkmoth Manduca sexta. Contrary to expectations, our results show that innate colour biases shift with changes in the visual environment, namely illuminance and background. This finding reveals that innate responses might emerge from a contextual integration of sensory inputs involved in object class recognition rather than from the deterministic matching of such inputs with a fixed internal representation.

Out of Context, Beyond the Face: Neuroanatomical Pathways of Emotional Face-Body Language Integration in Adolescent Offenders.

Background: Adolescent offenders (AOs) are characterized by social-norm transgression and aggressive behaviors. Those traits have been associated with alterations in socio-cognitive processes, including facial emotion recognition. While this would suggest that AOs tend to interpret negative emotional cues as threatening information, most research has relied on context-free stimuli, thus failing to directly track integrative processes typical of everyday cognition.Methods: In this study, we assessed the impact of body language and surrounding context on facial emotion recognition in AOs and non-offenders (NOs). We recruited 35 AOs from a reform school for young male offenders and 30 NOs matched for age and sex with the former group. All participants completed a well-validated task aimed to determine how contextual cues (i.e., emotional body language and surrounding context) influence facial emotion recognition through the use of congruent and incongruent combinations of facial and bodily emotional information.Results: This study showed that AOs tend to overvalue bodily and contextual signals in emotion recognition, with poorer facial-emotion categorization and increased sensitivity to context information in incongruent face-body scenarios. This pattern was associated with executive dysfunctions and disruptive behaviors, as well as with gray matter (GM) of brain regions supporting body-face recognition [fusiform gyrus (FG)], emotion processing [cingulate cortex (CC), superior temporal gyrus (STG)], contextual integration (precuneus, STG), and motor resonance [cerebellum, supplementary motor area (SMA)].Discussion: Together, our results pave the way for a better understanding of the neurocognitive association between contextual emotion recognition, behavioral regulation, cognitive control, and externalized behaviors in AOs.

Design requirements for contextual integration for train stations (Iraqi stations as a model)

The buildings of the railway stations are one of the important buildings that distinguish the cities and give them their identity and their special character through their association with the memory of the society that contains them. The importance of these centers as commercial and cultural centers, as well as their main function in transporting passengers and goods, To the atrophy of its effectiveness, so it must be protected and developed to contribute effectively in the performance of its diverse activities in an integrated manner and to serve the community at various levels and encourage the use of public transport. Therefore, many studies dealing with the concept of contextual integration of train stations have been discussed in an implicit or major manner. However, these studies were characterized by selectivity and lack of comprehensiveness in the treatments, especially with respect to the aspects of the contextual integration of the station in terms of design. Thus, the research problem was identified "the need to create a comprehensive theoretical view of the concept of contextual integration in the design of attractive local train stations " was identified. The aim of the research is to "crystallize a comprehensive theoretical conception of the aspects of contextual integration in the design of attractive local train stations".

Primary Care and Public Health Collaboration Reports: A Qualitative Review of Integration Aims, Participants, and Success Determinants.

This qualitative review of 57 published case reports aimed to analyze primary care and public health integration efforts in 45 states to summarize collaboration aims, participants, and systemic, organizational, and interactional success determinants. Chronic disease management, maternal and child health, and wellness and health promotion were the most commonly reported aims of collaboration between primary care and public health entities in the United States. Typical participants were government public health structures, health delivery systems, communities, academia, state professional medical associations, and employers and businesses. Systemic, organizational, and interactional determinants included adequate funding, multiple stakeholder engagement, leadership, data and information sharing, capitalization on collaborator resources, community engagement, steering committees, effective communication, regular meetings, shared mission, vision, and goals, previous positive relationships, collaborations, and partnerships. The present study contributes to the body of knowledge of when, where, and under what contextual circumstances collaboration and integration have been perceived as effective. Future research could extrapolate which determinants are more essential than others and focus on how systemic, organizational, and interactional factors are interrelated. To advance the practice of successful integration between primary care and public health entities, longitudinal research is needed to examine the degree of integration and sustainability.

A meta-analysis of context integration deficits across the schizotypy spectrum using AX-CPT and DPX tasks.

Schizotypy and schizophrenia involve disrupted context integration (CI), the ability to assimilate internal and external information into coherent mental representations. Research has primarily examined patients with schizophrenia, with fewer studies assessing CI in schizotypy-spectrum groups. The literature shows overall CI deficits, but mixed results for specific performance patterns and associations with clinical symptoms. Furthermore, conclusions are limited by small samples and heterogeneity across studies. To examine CI deficits across the schizotypy spectrum using AX-Continuous Performance Task (CPT) and Dot Pattern Expectancy task (DPX) performance. Systematic review involved searching 4 databases and 12 journals, examining key references, and contacting 227 researchers for published and unpublished data. Search terms included AX-CPT/DPX/dot pattern expectancy task/CNTRACs/context* integration/context* processing and schizo*/prodromal/high risk/psychosis; context* and ultra high risk. Independent data from studies with diagnostically or psychometrically assessed schizotypy-spectrum groups and AX-CPT/DPX tasks with 10+ trials and 60+% AX trials were included. Articles were independently coded by two authors using predefined coding schemes with good agreement. Meta-analyses pooled outcomes using random-effects models. Forty-one studies met inclusion criteria. CI impairment was present across the schizotypy spectrum. CI deficits in schizophrenia were substantial and associated with disorganized and negative symptoms. Outcomes were comparable between patients with chronic and first-episode schizophrenia. At-risk groups demonstrated moderate CI impairment. Results were robust across task parameters and there was no evidence that reporting biases grossly impacted outcomes. Findings lend support to theories suggesting that CI is a stable vulnerability factor for schizophrenia. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Paramedic and physician perspectives on the potential use of remotely supported prehospital ultrasound.

During remotely supported prehospital ultrasound (RSPU), an ultrasound operator performs a scan and sends images to a remote expert for interpretation. This novel technology has been undergoing investigation in the randomised controlled SatCare trial, which seeks to assess the capability of RSPU to improve patient outcomes and standard of prehospital care in the Highlands of Scotland. This study aimed to explore the views of emergency medicine physicians and paramedics prior to starting the trial. An interview schedule was prepared a priori and was based upon normalisation process theory (NPT), which can be used to assess ways in which practitioners work to embed novel technologies in clinical practice. Semi-structured interviews were conducted with four consultant physicians and eight paramedics, who were recruited using purposive sampling until theoretical saturation. Analysis used open and hierarchical axial coding, and NPT as a framework to assist in the management and analysis of codes. The prospect of RSPU evoked significantly different responses from emergency care physicians and paramedics. Paramedics thought of RSPU as a logical progression of prehospital care, which addresses core prehospital challenges such as lack of decision-making support and a limited ability to identify life-threatening occult conditions. Paramedics saw RSPU as part of a trend to increase their skills and responsibilities, and viewed ultrasound as a validated tool within emergency medicine. Paramedics felt that ultrasound was simple to learn and would be practical for use within the prehospital arena. In contrast, physicians expressed a greater spectrum of views; most saw limited value to prehospital diagnosis and were concerned that RSPU would distract both paramedics and physicians from their existing roles (particularly in the context of the increasing demand and workload within Scotland's publicly funded National Health Service). Physicians were also concerned that ultrasound skills were poorly incorporated into training and practice in the British emergency medicine system. Furthermore, they believed that ultrasound was difficult to learn, prone to misinterpretation and easy to become deskilled in. Both sets of participants believed that the relational skills required between the two groups and the practical complexities of RSPU may pose challenges in its implementation. In particular, concerns were raised regarding the time that would be required to conduct the ultrasound scans and difficulties with transmission and communication in the Highlands. Both groups questioned the likelihood of measurable benefits from RSPU for patients. Furthermore, both groups were unsure how the technology would benefit those patients in urban areas close to the emergency department or whether RSPU would be effectively utilised in rural areas where serious emergencies are infrequent. There are substantial differences in emergency physician and paramedic perspectives on RSPU; however, both parties were willing to engage with the research process. Both groups have reservations, especially the emergency physicians who perceive significant barriers to the acquisition of skills, as well as the relational and contextual integration of RSPU. This study demonstrates the importance of conversations with physicians and paramedics throughout the research process, particularly as the role of prehospital care remains controversial.

Background Odors Modulate N170 ERP Component and Perception of Emotional Facial Stimuli.

Successful social interaction relies on the accurate decoding of other peoples’ emotional signals, and their contextual integration. However, little is known about how contextual odors may lead to modulation of cortical processing in response to facial expressions. We investigated how unpleasant and pleasant contextual background odors affected emotion perception and cortical event-related potential (ERP) responses to pictures of faces expressing happy, neutral and disgusted facial expressions. Faces were, regardless of expression, rated more positively in the pleasant odor condition and more negatively in the unpleasant odor condition. Faces were overall rated as more emotionally arousing in the presence of an odor, irrespective of its valence. Contextual odors also interacted with facial expressions, such that happy faces were rated as especially non-arousing in the unpleasant odor condition. The early, face-sensitive N170 ERP component also displayed an interaction effect. Here, disgusted faces were affected by the odor context such that the N170 revealed a relatively larger negativity in the context of a pleasant odor compared with an unpleasant odor. There were no odor effects on the responses to faces in other measured ERP components (P1, VPP, P2, and LPP). These results suggest that odors bias socioemotional perception early stages of the visual processing stream. However, effects may vary across emotional expressions and measurements.

Automatized integration of a contextual model into a process with data variability

Existent process models can hardly cope with the emerging issue of modelling exponential variable data volumes in systems’ workflow, from specifications to operation. Given the strong relation between data context and data variability, this paper considers the automated integration of contextual models for processes with data variability. The proposed approach extends methodologically a platform independent model process, using a contextual data model, to obtain automatically the corresponding platform specific model. Contextual data are thus integrated to a process as a model, within a process. Two particular cases of contextual data models are studied in detail: substitution, when the contextual data model defines generated code, and enhancement, when learned data descriptions constitute the contextual data model. The feasibility and value of integrating a contextual model into a process to handle data variability are shown in detail describing these two use cases. Contextual model integration by substitution to include automatically variable ready to use application services to generate code, and contextual model integration by enhancement applied to supervised image classification based on variable descriptors. Results show that relating data variability and its context by means of automated integration of a designed system component model, simplifies variable data processing of system process models.

Effects of affective and emotional congruency on facial expression processing under different task demands

Contextual influences on responses to facial expressions of emotion were studied using a context-target paradigm that allowed distinguishing the effects of affective congruency (context and target of same/different valence: positive or negative) and emotional congruency (context and target representing the same/different emotion: anger, fear, happiness). Sentences describing anger, fear or happiness-inducing events and faces expressing each of these emotions were used as contexts and targets, respectively. While between-valence comparisons (context and target of similar/different valence) revealed affective congruency effects, within-valence comparisons (context and target of similar valence and same/different emotion) revealed emotional congruency effects. In Experiment 1 no evidence of emotional congruency and limited evidence of affective congruency were found with an evaluative task. In Experiment 2 effects of both affective and emotional congruency were observed with an emotion recognition task. In this case, angry and fearful faces were recognized faster in emotionally congruent contexts. In Experiment 3 the participants were asked explicitly to judge the emotional congruency of the target faces. Emotional congruency effects were again found, with faster judgments of angry and fearful faces in the corresponding emotional contexts. Moreover, judgments of angry expressions were faster and more accurate in happy than in anger contexts. Thus, participants found easier to decide that angry faces did not match a happy context than to judge that they did match an anger context. These results suggest that there are differences in the way that facial expressions of positive and negative emotions are discriminated and integrated with their contexts. Specifically, compared to positive expressions, contextual integration of negative expressions seems to require a double check of the valence and the specific emotion category of the expression and the context.

Preserving sense of place at historic waterfronts in malaysia

Historical preservation is important to protect significant historic resources from destruction and inappropriate changes. Urban waterfronts are unique cultural resources that have its own identity, represent the lifestyle of surrounding communities. Over the years, the activities along the waterfront have changed along with city development, resulting in the loss of sense of place. In recent years, the agenda of preservation the cultural value of waterfront areas has been a research focus among the civil society and NGOs. However, in the midst of rapid development, this aspect is often overlooked and deteriorates the historical values of the place. At the same time, the quality of life of waterfront communities is also affected. This conceptual paper is a call for a set of actions to ensure that historical values at these places are protected. Through content analysis from previous literature reviews, this paper investigates how regeneration of historic waterfronts can help in preserving sense of place and improve the quality of life among waterfront communities. Findings from the literature revealed that contextual integration is important for successful redevelopment of historic waterfronts in order to preserve their sense of place.

Drug target ontology to classify and integrate drug discovery data

BackgroundOne of the most successful approaches to develop new small molecule therapeutics has been to start from a validated druggable protein target. However, only a small subset of potentially druggable targets has attracted significant research and development resources. The Illuminating the Druggable Genome (IDG) project develops resources to catalyze the development of likely targetable, yet currently understudied prospective drug targets. A central component of the IDG program is a comprehensive knowledge resource of the druggable genome.ResultsAs part of that effort, we have developed a framework to integrate, navigate, and analyze drug discovery data based on formalized and standardized classifications and annotations of druggable protein targets, the Drug Target Ontology (DTO). DTO was constructed by extensive curation and consolidation of various resources. DTO classifies the four major drug target protein families, GPCRs, kinases, ion channels and nuclear receptors, based on phylogenecity, function, target development level, disease association, tissue expression, chemical ligand and substrate characteristics, and target-family specific characteristics. The formal ontology was built using a new software tool to auto-generate most axioms from a database while supporting manual knowledge acquisition. A modular, hierarchical implementation facilitate ontology development and maintenance and makes use of various external ontologies, thus integrating the DTO into the ecosystem of biomedical ontologies. As a formal OWL-DL ontology, DTO contains asserted and inferred axioms. Modeling data from the Library of Integrated Network-based Cellular Signatures (LINCS) program illustrates the potential of DTO for contextual data integration and nuanced definition of important drug target characteristics. DTO has been implemented in the IDG user interface Portal, Pharos and the TIN-X explorer of protein target disease relationships.ConclusionsDTO was built based on the need for a formal semantic model for druggable targets including various related information such as protein, gene, protein domain, protein structure, binding site, small molecule drug, mechanism of action, protein tissue localization, disease association, and many other types of information. DTO will further facilitate the otherwise challenging integration and formal linking to biological assays, phenotypes, disease models, drug poly-pharmacology, binding kinetics and many other processes, functions and qualities that are at the core of drug discovery. The first version of DTO is publically available via the website http://drugtargetontology.org/, Github (http://github.com/DrugTargetOntology/DTO), and the NCBO Bioportal (http://bioportal.bioontology.org/ontologies/DTO). The long-term goal of DTO is to provide such an integrative framework and to populate the ontology with this information as a community resource.

Managing Persistent Tensions on the Frontline: A Configurational Perspective on Ambidexterity

AbstractAmbidexterity research has noted that firms’ simultaneous pursuit of exploration and exploitation causes organizational tensions that are difficult to resolve. To make these tensions manageable, scholars have generally suggested that senior managers take the central role in designing organizational solutions, such as the structural separation or contextual integration of the exploratory and exploitative tasks. Yet, in an inductive study of ten corporate innovation initiatives, we find that our informants assigned far less importance to the senior managers’ initial design choices than to the frontline managers’ subsequent configurational practices. Frontline managers used these practices to constantly adapt and align their initiatives’ organizational contexts, which allowed them to cope with persistent exploration‐exploitation tensions in their daily business activities. Based on these empirical insights and drawing on paradox theory, we develop a configurational perspective on ambidexterity, where frontline managers play a more central, proactive, and strategic role than purported by the established design perspective on ambidexterity.

Modeling socially responsible consumption and the need for uniqueness: a PLS-SEM approach

PurposeThe purpose of the present study is intended to fill a research gap, by advancing a conceptual model which brings novel insights on the relationships between socially responsible consumption and consumer’s need for uniqueness.Design/methodology/approachRelying on a questionnaire-based survey for data collection, the proposed model was tested using the partial least squares (PLS) algorithm for structural equation modeling (SEM), which allows the assessment of the models containing both formative and reflective constructs.FindingsThe research found that 73.7 per cent of the variance in the consumer’s belief in the importance of personal power to make a difference through socially responsible choices is explained by the proposed model. Moreover, four of the five factors of socially responsible consumption fully mediate the positive effect of the consumer’s need for uniqueness on the importance attached to personal socially responsible choices in driving positive change.Research limitations/implicationsThe study avails a phenomenological perspective by offering novel insights from a Romanian sample. The limitation associated with a country-centric vision is compensated through the contextual analysis and integration of a new point of reference in the overall framework of socially responsible consumption.Practical implicationsThe evidence is indicative of new consumption insights and should be closely considered by companies.Originality/valueThe study draws upon a conceptual model integrating the relationships between socially responsible consumption and a psychological characteristic – the consumer’s need for uniqueness – which has been never tested as such before.
