New ventures: how team motivation affects financial outcomes
Authors: Debrulle Jonas , Maes Johan , Gardiner Elliroma 
Published: August 2020

Purpose
The purpose of this paper is to contribute to understanding the impact of entrepreneurial team composition on new venture performance. Different types of entrepreneurship motivation among founding team members are defined. Using a relatively recent theory as a framework (i.e. self-determination theory), the authors group these motives into two categories: autonomous and controlled motivation. The business impact of the level of each type of motivation within the team, as well as the impact of having team members with different motivational drivers, is examined. New venture performance is modelled in two different ways: financial performance (i.e. return on assets) and innovation performance.

Design/methodology/approach
The analyses are based on 66 founding teams active in diverse activity sectors. The teams represent a total of 142 business founders. Data was collected through structured interviews, a company questionnaire and a secondary data source (i.e. certified financial statements).

Findings
The results confirm that the level of autonomous motivation within the team contributes to start-up financial performance, whereas the level of controlled motivation hampers innovation performance. No direct effects of diversity of team member motivation on start-up performance were discovered.

Originality/value
This is one of the first papers to study multiple firm performance effects of the composition of entrepreneurial founding teams in terms of motivation.
Dignity of the heritage and the heritage communities
Authors: Alatalu Riin 
Published: August 2020

PurposeThe purpose of this paper is to discuss the reasons why the human rights-based approach should be used in the preservation of cultural heritage.Design/methodology/approachThe article is a combination of an essay and illustrative case studies. The thesis is based on experience in heritage protection on national and international level and the discussions of the “Heritage and Human Rights” training in Estonia 1.-6.05.2019.FindingsCultural heritage is the common good regardless of its ownership. The protection of something, especially in living environments, includes compromises in the rights of one or another counterpart. Restrictions are often ground for conflicts that can be settled with good communication, but sometimes just communication is not enough. In these cases, human rights-based approaches enable to identify the problems, scale the rights of different stakeholders and thus enable discussion to reach consensus.Practical implicationsThe research is useful for heritage conservationists, policy makers and urban planners with regards to management and implementation of human rights-based approach and community involvement in heritage protection on World Heritage, national and local levels.Originality/valueThe research is a part of a series of discussions, trainings and project reports of the Our Common Dignity – Rights Based Approaches (OCD-RBA) working group of the International Council on Monuments and Sites (ICOMOS) and contributes to the follow-up activities worldwide.
Internal communication education in universities of applied sciences in the Netherlands
Authors: Hendrawan Bram , Elshof Marjon , Verkuil Lisanne 
Published: August 2020

PurposeA growing body of scholarly research focuses on internal communication (IC), which, over the past decade, has become an important specialisation within the field of communication. However, little scholarly attention has been paid to IC education, resulting in a lack of academic knowledge about the state of IC education. This paper focuses on investigating IC education in communication studies curricula at Dutch universities of applied sciences.Design/methodology/approachUsing a combination of content analysis of IC modules in Bachelor of Communication programmes (n = 19) and qualitative analysis of semi-structured interviews with IC educators (n = 8), this article sheds lights on the contours of IC education and its relationship with practice.FindingsEducation has become an integral part of the IC profession in the Netherlands. The analysis shows that while the modules address some important topics found in the literature on IC, there are some gaps. In regard to knowledge topics, the modules reflect broader trends in IC by addressing important topics like change management, internal branding and digitalisation. However, there is a gap in the competencies in the modules and what is considered important in the literature.Practical implicationsThe findings can help educators improve the quality of their curriculum. For IC practitioners, professional associations in particular, this paper provides insight into the state of education of future IC professionalsOriginality/valueStudies that look at the education of communication professionals have focused mainly on the field of public relations. This paper reports on the first empirical study to investigate the state of IC education in the context of higher education.
Bracketing: a phenomenological theory applied through transpersonal reflexivity
Authors: Dörfler Viktor , Stierand Marc 
Published: August 2020

PurposeThe purpose of this study is to improve our understanding of bracketing, one of the most central philosophical and theoretical constructs of phenomenology, as a theory of mind. Furthermore, we wanted to showcase how this theoretical construct can be implemented as a methodological tool.Design/methodology/approachIn this study we have adopted an approach similar to a qualitative meta-synthesis, comparing the emergent patterns of two empirical projects, seeking synergies and contradictions and looking for additional insights from new emerging patterns.FindingsOn a philosophical level, we have found that bracketing, as a theoretical construct, is not about the achievement of objectivity; quite to the contrary, it embraces subjectivity and puts it centre-stage. On a theoretical level, we have achieved a better understanding of Husserl's phenomenology, as a theory of mind. On a methodological level, we have achieved a powerful way of supplementing and/or clarifying research findings, by using a theoretical construct as a methodological tool.Originality/valueOur paper contributes to the phenomenology literature at a philosophical, theoretical and methodological level, by offering a better understanding and a novel implementation of one of the central theoretical constructs of phenomenology.
Ultraviolet light-initiated preparation of phase change material microcapsules and its infrared imaging effect on fabric
Authors: Gu Mingqi , Zhang Wei , Hao Shang , Liu Xiaochen , Zhang Zichao , Shao Fenjuan 
Published: August 2020

Purpose
This study aims to explore the infrared imaging effect of fabrics coated with phase change material microcapsules (PCM-MCs), which are prepared by the initiation of ultraviolet (UV) light.

Design/methodology/approach
PCM-MCs were prepared by UV polymerization using paraffin (PA) as core material, polymethyl methacrylate as wall material and ferric chloride as photoinitiator. The effects of emulsifier dosage and emulsification temperature on the properties of PA emulsion were investigated. Scanning electron microscopy, particle size analysis, infrared spectroscopy, differential scanning calorimetry and infrared imaging test were used to characterize the properties of microcapsules.

Findings
The PCM-MCs with good morphology and particle size were prepared with 25 cm of the distance between light source and the liquid. The average particle size was 1.066 µm and the latent heat of phase transition was 19.96 J/g. After 100 accelerated thermal cycles, the latent heat only decreased by 1.8%. It had good heat storage stability and thermal stability. The fabric coated by the microcapsules exhibited a variable temperature hysteresis effect when placed in the sun, and presented a color close to the infrared images of the human palm under the external environment temperature close to the human body temperature.

Research limitations/implications
The PCM-MCs prepared based on UV light initiation showed good thermal properties and its coated fabrics had an infrared decoy effect below the temperature of the human body.

Practical implications
This study explored the application of microcapsules in textiles.

Originality/value
The microcapsules had a certain application potential in infrared decoy effect.

Authors: Zhao Yuzhen , Zhao Yang , Kang Xiaoxi , Miao Zongcheng , Zhang Haiquan 
Published: August 2020

Purpose
This paper aims to compare the electronic properties of perylene diimide derivatives (DFPDI) and its anion radical (DFPDI.-k.+) thin film by drop-coating of organic molecules on the interdigitated electrodes.

Design/methodology/approach
The authors compared the electronic properties of perylene diimide derivatives and its anion radical by drop-coating of organic molecules on interdigitated electrodes. Significantly, the current of perylene diimide derivatives anion radical increased by 2∼3 orders of magnitude compared to perylene diimide derivatives under a bias of 5 V, and the maximal current of anion radical that from tetrahydrofuran solution can reach 3.6 mA. Furthermore, DFPDI.-k.+ thin film showed time-resistance sensitivity for acetic acid. When DFPDI.-k.+ thin film was placed in acetic acid of 3.1 × 105 ppm, the current was decreased 46 times under a bias of 6 V after 8 min.

Findings
We developed the new method to prepare ambient stable perylene diimide derivatives anion radical, which shows sensitivity of absorption spectra to acid.

Originality/value
Perylene diimide derivatives anion radical thin film showed time-resistance sensitivity for acetic acid, suggesting potential application of perylene diimide derivatives anion radical as acid sensor.
Fieldworking the relational complexity of organizations
Authors: Mosleh Wafa Said , Larsen Henry 
Published: August 2020

PurposeThe purpose of this paper is to present researcher's reflexive writing about emergent events in research collaborations as a way of responding to the process-figurational sociology of Norbert Elias in the practice of organizational ethnography.Design/methodology/approachDrawing parallels between Norbert Elias' figurative account of social life and auto-ethnographic methodology, this paper re-articulates the entanglement of social researchers in organizational ethnographic work. Auto-ethnographic narration is explored as means to inquire from within the emerging relational complexity constituted by organizational dynamics. Writing about emergent events in the research process becomes a way of inquiring into the social figurations between the involved stakeholders; thus nurturing sense-making and increasing the awareness and sensitivity of the researcher to her own entanglement with the relational complexity of the organization under study.FindingsIn the paper, we argue that the writing of auto-ethnographic narratives of emergent field encounters is a process of inquiry that continuously depicts the temporal development of the relational complexity in organizations. Viewing that from the perspective of Elias' concept of figuration, we find a common commitment to the processual nature of research processes, which insists on moving beyond objectifying empirical insights.Originality/valueThis paper encourages awareness of the interdependency between ourselves as social researchers and field actors as we engage with the field. It moves beyond simplifying the ethnographic research agenda to that of “studying” and “describing” organizations. It offers unique insights into the organizational context, and increased sensitivity toward the social entanglement of the experiences that we, ourselves, as researchers are part of.
Effects of rotation and varying gravity on the onset of convection in a porous medium layer: a numerical study
Authors: Yadav Dhananjay 
Published: August 2020

Purpose
The purpose of this study is to examine the influence of rotation and varying gravitational strength on the onset of thermal convection in a porous medium layer numerically. The porous layer is acted to uniform rotation and inconsistent downward gravitational field which changing with depth from the layer. The authors presented three categories of gravitational strength deviancy, namely, linear, parabolic and exponential.

Design/methodology/approach
The higher-terms Galerkin weighted residual procedure is applied to get the eigenvalue of the problem.

Findings
The results illustrate that both rotation parameter and gravity variation parameter suspend the arrival of convection. The measurement of the convection cells decreases on enhancing the rotation parameter and gravity variation parameter.

Originality/value
It is also found that the scheme is more stable for category exponential, whereas it is more unstable for category parabolic.

AbstractAimTo evaluate left ventricular (LV) dysfunction in patients with rheumatoid arthritis (RA) and to determine the impact of biological treatment on LV function in these patients using global circumferential strain (GCS), global longitudinal strain (GLS) and global radial strain (GRS) values assessed by feature tracking cardiac magnetic resonance (FT‐CMR) imaging.MethodsEighty patients with RA and 20 controls without cardiovascular disease underwent non‐contrast CMR imaging. Patients with RA received conventional synthetic disease‐modifying antirheumatic drugs (csDMARDs) or biologic DMARDs (bDMARDs). Global strains were calculated in 16 LV segments.ResultsNo significant differences in cardiovascular risk factors were found between the RA group and controls. GCS was 21% lower in the RA group compared with controls (P < 0.001) and was 14% lower in the csDMARDs group compared with the bDMARDs group (P = 0.002), whereas, there was no significant difference in GLS and GRS between the RA group and the controls. In regard to strain rates, diastolic GCS and GRS rates were significantly lower in the RA group (P < 0.001, 0.011, respectively). In univariate analyses, GCS was significantly associated with the Simplified Disease Activity Index, bDMARDs, swollen joint count, anti‐cyclic citrullinated peptides antibodies and matrix metalloproteinase‐3, but in multivariable analysis, only bDMARDs was significantly associated with GCS (P = 0.021).ConclusionGlobal circumferential strain, GLS and GRS assessed by FT‐CMR can reveal subclinical LV dysfunction in patients with RA. Furthermore, they can be used to determine the normalization of LV regional dysfunction induced by bDMARDs possibly related to disease activity reduction.

Published: August 2020

BackgroundBone metastasis (BoM) is common in patients with advanced non‐small cell lung cancer (NSCLC) and considered as one of the negative prognostic factors. However, the impact of BoM on clinical outcomes of patients with advanced NSCLC treated with immune checkpoint inhibitors (ICIs) remains unclear.MethodsA total of 103 patients treated with ICI monotherapy and 101 patients treated with ICIs combined with chemotherapy or antiangiogenesis therapy were retrospectively analyzed. The differences in progression‐free survival (PFS), overall survival (OS) and objective response rate (ORR) between BoM+ and BoM− were investigated.ResultsOf those 101 patients who received combination therapy, no significant difference between BoM− and BoM+ in terms of both median PFS and median OS (median PFS, 10.1 vs. 12.1 months, P = 0.6; median OS, NR vs. 24.6 months, P = 0.713) was determined. In contrast, of the 103 patients who received ICI monotherapy, BoM+ patients had an inferior PFS (4.2 vs. 6.7 months, P = 0.0484) and OS (12.5 vs. 23.9 months, P = 0.0036) compared with BoM− patients. The univariate and multivariate analysis in the ICI monotherapy group also identified BoM as an independent factor attenuating the efficacy of ICI monotherapy. Of all BoM+ patients who received ICI monotherapy, neither palliative radiotherapy nor bisphosphonate drugs improved OS (palliative radiotherapy: 12.5 vs. 16.7 months, P = 0.487; bisphosphonate drugs: 12.5 vs. 9.7 months, P = 0.568).ConclusionsBoM attenuated the efficacy of ICI monotherapy in patients with advanced NSCLC. Of BoM+ patients who received ICI monotherapy, neither palliative radiotherapy nor bisphosphonate drugs improved OS. Other therapeutic strategies are needed for patients with BoM.
Signifiers for the divine
Authors: ITZHAK NOFIT 
Published: August 2020

ABSTRACTLe Rocher is a Catholic charismatic NGO concerned with ameliorating the living conditions of immigrant populations in the French cités, or peripheral neighborhoods. While scholarly accounts define humanitarian practice through the idiom of compassion, Le Rocher's volunteers find compassion irrelevant to their endeavor. Instead, they articulate their mission in terms of their relationship with God, and in doing so they introduce God as an agent into the relational dynamic of the humanitarian encounter. This introduction of a third element into an otherwise dyadic relationship opens up possibilities for mutuality in a social setting in which relationships are typically defined as nonreciprocal. This highlights the need to take seriously God's agency in shaping the lives of religious actors, raising questions about the broader role that mediation, divine or otherwise, plays in establishing social relations in the contexts of aid and beyond.

AbstractLactobacillus rhamnosus GG (LGG) is increasingly applied in functional food products and acts as a probiotic model in nutritious and clinical studies. Increasing evidences have revealed the immune modulation of LGG on macrophages. The aim of this study is to investigate the effect of LGG on macrophage polarization of murine bone marrow‐derived macrophages (BMDMs). BMDMs were treated with 108 colony‐forming units (CFU)/ml LGG for 1.5, 3, and 6 hr. Results showed that LGG obviously upregulated the mRNA expression of M1‐associated cytokines (p < .05), including interleukin‐1 beta (IL‐1β), IL‐6, tumor necrosis factor‐alpha (TNF‐α), and inducible nitric oxide synthase (iNOS), whereas had no effect on the expression of M2‐associated markers (p > .05), including arginase 1 (Arg1), mannose receptor, and chitinase‐like protein 3 (YM1). Furthermore, LGG markedly increased the expression of pro‐inflammatory cytokines (IL‐12p40, cyclooxygenase‐2 [COX‐2], and interferon‐γ [IFN‐γ]) (p < .05) and anti‐inflammatory cytokines (IL‐10, IL‐4, and transforming growth factor‐β [TGF‐β]) (p < .05). In addition, we also found that TLR2/MyD88/MAPK signaling pathway was required for LGG‐induced M1 macrophage polarization and M1‐related cytokines expression. Together, these findings demonstrate that probiotic LGG facilitates M1 polarization of BMDMs, suggesting that LGG may have an immunotherapeutic potential in regulating the host defense against pathogen invasion.
Rhabdomyomatous mesenchymal hamartoma presenting as a chin nodule in a 15‐year‐old male

Published: August 2020

AbstractRhabdomyomatous mesenchymal hamartoma (RMH), also known as congenital midline hamartoma and striated muscle hamartoma, is a rare congenital malformation presenting most commonly in midline sites of the head and neck region. Since its first description in 1986, 67 cases have been reported to date. We report a case of RMH presenting as a chin nodule in an otherwise healthy 15‐year‐old male. The patient presented with a dome‐shaped subcutaneous lesion on his chin which had been present since birth, but had grown and was interfering with his ability to shave. He otherwise had no history of congenital anomalies or malformations. Histopathological examination of the excised lesion revealed a haphazard proliferation of striated muscle admixed with adipose tissue and adnexal structures within the dermis and subcutaneous tissue, consistent with a diagnosis of RMH. While the majority of reported cases are of newborns or children under 3 years of age, RMH may not come to clinical attention until later in life. This rare malformation should be included in the differential diagnosis of lesions containing dermal striated muscle and/or adipose tissue, to include nevus lipomatosus superficialis, fibrous hamartoma of infancy, neuromuscular choristoma, fetal rhabdomyoma, and rhabdomyosarcoma.
A comparison of global and egocentric network approaches for assessing peer alcohol use among college students in the United States
Authors: Russell Alex M. , Barry Adam E. , Patterson Megan S. 
Published: August 2020

AbstractIntroduction and AimsPerceptions of peer alcohol use have a strong influence on college students' personal alcohol consumption. Common strategies for measuring students' perceptions of peer alcohol use rely on global student body questions (e.g. ‘typical’ student use), which overlook the true social contexts of college students. Simply put, persons most likely to influence an individual's behaviour are their closest, most proximal peers. Our objective was to compare whether social norms measures or network measures of peer alcohol use better assess participant alcohol use. Specifically, we compared: (i) perceptions of the ‘typical’ student's drinking behaviours; versus (ii) egocentric social network measures, in which respondent's report perceptions of the drinking behaviours of personally identified peers.Design and MethodsThree hundred and nine college students reported demographics, personal alcohol use and global perceptions of peer alcohol use. Egocentric network composition was calculated using E‐Net. Descriptive statistics and hierarchical linear regression analyses predicting personal drinking (AUDIT‐C) were conducted in SPSS.ResultsRespondent's perceptions of peers' drinking behaviours accounted for 9.7% of the variance in personal alcohol use beyond demographics, global perceptions of peer alcohol use and network composition demographics [F(3,280) = 13.391, P < 0.001]. Egocentric social network measures explained more variability in peer influence on personal alcohol consumption than global campus measures.Discussion and ConclusionsPersonally identified peers have a greater influence on personal alcohol consumption than perceptions of ‘typical students’. Thus, future studies would benefit from utilising an egocentric network approach to examine the complex, interpersonal nature of alcohol use among college students.
