The preliminary results of physiotherapy scoliosis-specific exercises on spine joint position sense in adolescent idiopathic scoliosis: A randomized controlled trial
Authors: Akyurek Elcin , Zengin Alpozgen Ayse , Akgul Turgut 
Published: June 2022

Background:
It has been observed that there are difficulties in maintaining spinal harmony in the absence of proprioceptive information, which has an important role in achieving postural control in scoliosis. One of the tests used to evaluate proprioceptive mechanisms is joint position reproduction.

Objective(s):
The main aim of our study was to investigate the effect of physiotherapy scoliosis-specific exercise (PSSE) on spine joint reposition (JR) sense. The second aim was to determine the effects of PSSE on the angle of trunk rotation (ATR), posture, and deformity perception in adolescent idiopathic scoliosis.

Methods:
Twenty-nine patients with adolescent idiopathic scoliosis (mean age 13.79 ± 1.82 years) were randomly allocated to two groups. “Schroth” exercises were applied to the PSSE group for 8 weeks (16 sessions). The control group was placed on the waiting list. Patients' JR error (dual inclinometer), ATR (scoliometer), posture parameters (PostureScreen Mobile, Posterior Trunk Asymmetry Index, and Anterior Trunk Asymmetry Index), and deformity perception (Walter Reed Visual Assessment Scale [WRVAS]) were assessed at the first session and at the end of 8 weeks.

Results:
The initial demographic characteristics, Cobb (thoracal: 19.41 ± 7.03 degrees; lumbar: 20.76 ± 7.24 degrees) and ATR (thoracal: 5.86 ± 3.98 degrees; lumbar: 5.66 ± 3.33 degrees) and clinical test parameters of the groups (JR, posture parameters, and WRVAS) were similar (P > .05). According to the findings, thoracal and lumbar JR error values (P < .05), ATR (P ≤ .001), posture parameters (P ≤ .001), and WRVAS (P = .048) were significantly improved in the PSSE group. Besides, when the groups were compared, a significant difference was found in favor of PSSE except for the deformity perception (P < .05).

Conclusions:
Schroth exercises have a positive contribution for improving JR sense of the spine, vertebral rotation, and posture.

ABSTRACTAdvanced high-grade serous ovarian cancer (HGSC) is an aggressive disease that accounts for 70% of all ovarian cancer deaths. Nevertheless, 15% of patients diagnosed with advanced HGSC survive more than 10 years. The identification of predictive markers associated with tumors developed from these long-term survivors (LTS) is crucial to identifying therapeutic targets for the disease, and thus improving patient survival rates. Reports to date have not fully established the stromal heterogeneity of the tumor microenvironment (TME) in ovarian cancer and its association with clinical outcomes. We used a spatial transcriptomics platform to generate spatially resolved transcript profiles in treatment naïve advanced HGSC from LTS and short-term survivors (STS), and determined whether cancer-associated fibroblasts (CAFs) heterogeneity is associated with survival in patients with advanced HGSC. We integrated spatial transcriptomics with single-cell RNA sequencing data to distinguish tumor and stroma regions, and developed a method to investigate spatially resolved ligand-receptor interactions between various tumor and CAF subtypes in the TME. In addition, we used multiplex immunohistochemistry techniques to validate our findings. We found that a specific subtype of CAFs and its spatial location relative to a particular ovarian cancer cell subtype in the TME correlate with long-term survival in advanced HGSC patients. We also demonstrated that significant APOE-LRP5 crosstalk occurred at the stroma-tumor interface in tumor tissues from STS compared to LTS, suggesting that such crosstalk plays a crucial role in modulating the malignant phenotype of HGSC, and could serve as a predictive biomarker of patient survival.

AbstractObjectiveTo investigate clinical symptoms, cognitive performance and cortical activity following mild traumatic brain injury (mTBI).MethodsThirty individuals in the sub-acute phase post mTBI and 28 healthy controls with no history of head injury were compared on clinical, cognitive and cortical activity measures. Measures of cortical activity included; resting state EEG, task related EEG and combined transcranial magnetic stimulation with electroencephalography (TMS-EEG). Primary analyses investigated clinical, cognitive and cortical activity differences between groups. Exploratory analyses investigated the relationships between these measures.ResultsAt 4 weeks’ post injury, mTBI participants exhibited significantly greater post concussive and clinical symptoms compared to controls; as well as reduced cognitive performance on verbal learning and working memory measures. mTBI participants demonstrated alterations in cortical activity while at rest and in response to stimulation with TMS.ConclusionsThe mTBI group demonstrated neurophysiological markers of altered excitatory and inhibitory processes which impact neural function. Further research is needed to explore the relationship between these pathophysiologies and clinical/cognitive symptoms in mTBI.

AbstractThe transition to technologically-assisted communication has permeated all facets of human social life; yet, its impact on the social brain is still unknown and the effects may be most notable during key developmental transitions. Applying a two-brain perspective, the current pre-registered study measured mother-child brain-to-brain synchrony using hyperscanning EEG at the transition to adolescence during live face-to-face interaction versus technologically-assisted remote communication. The live interaction elicited 9 significant cross-brain links between densely inter-connected frontal and temporal areas in the beta range [14-30 Hz]. Mother’s right frontal region connected with child’s right and left frontal, temporal, and central regions, suggesting its regulatory role in organizing the two-brain dynamics. In contrast, the remote interaction elicited only 1 significant cross-brain-cross-hemisphere link, attenuating the robust right-to-right-brain connectivity during live social moments that communicates socio-affective signals. Furthermore, while the level of social behavior was comparable between the two interactions, brain-behavior links emerged only during the live exchange, suggesting that remote interactions yield a somewhat thinner biobehavioral experience. Mother-child right temporal-temporal synchrony linked with moments of shared gaze and the degree of child engagement and empathic behavior was associated with right frontal-frontal synchrony. Our findings indicate that human co-presence is underpinned by specific neurobiological processes, suggest potential reasons for "zoom fatigue", and open a much-needed discussion on the cost of social technology for brain maturation, particularly among youth.HighlightsTechnologically-assisted communication is prevalent; yet, its impact on the social brain is unknownWe measured mother-child brain-to-brain synchrony during live and technologically-assisted remote interactionThe live interaction elicited 9 cross-brain links between densely inter-connected frontal and temporal areas in the beta rangeThe remote interaction yielded only 1 significant cross-brain cross-hemisphere linkBrain-behavior linked emerged only during the live interactionFurther research should examine the cost of social technology to brain maturation, particularly among youth.

AbstractAge-related cognitive impairment is multifactorial, with numerous underlying and frequently co-morbid pathological correlates. Amyloid beta (Aβ) plays a major role in Alzheimer’s type age-related cognitive impairment, in addition to other etiopathologies such as Aβ-independent hyperphosphorylated tau, cerebrovascular disease, and myelin damage, which also warrant further investigation. Classical methods, even in the setting of the gold standard of postmortem brain assessment, involve semi-quantitative ordinal staging systems that often correlate poorly with clinical outcomes, due to imperfect cognitive measurements and preconceived notions regarding the neuropathologic features that should be chosen for study. Improved approaches are needed to identify histopathological changes correlated with cognition in an unbiased way. We used a weakly supervised multiple instance learning algorithm on whole slide images of human brain autopsy tissue sections from a group of elderly donors to predict the presence or absence of cognitive impairment (n = 367 with cognitive impairment, n = 349 without). Attention analysis allowed us to pinpoint the underlying subregional architecture and cellular features that the models used for the prediction in both brain regions studied, the medial temporal lobe and frontal cortex. Despite noisy labels of cognition, our trained models were able to predict the presence of cognitive impairment with a modest accuracy that was significantly greater than chance. Attention-based interpretation studies of the features most associated with cognitive impairment in the top performing models suggest that they identified myelin pallor in the white matter. Our results demonstrate a scalable platform with interpretable deep learning to identify unexpected aspects of pathology in cognitive impairment that can be translated to the study of other neurobiological disorders.

Published: June 2022

PurposeThe aim of this paper is to study the challenges of digital advertising from the characterization of the influencer phenomenon based on the perceptions of two different and non-consecutive generations, explored from the perspective of parasocial relationshipsDesign/methodology/approachUsing a quantitative methodology design and a descriptive approach, a study is presented on a sample of 449 individuals belonging to two generational niches, generation Z (N = 227) and generation X (N = 222). For the study, characterization parameters have been defined based on existing literature, defining five-dimension conceptualization: strength, fairness, engagement, trustworthiness and social role.FindingsThe results point to a different perception of the phenomenon in some aspects that allow an intergenerational portrait of the figure of the influencer to be made. The findings of the study are innovative because they were not previously available and transcend academia to serve the companies that proliferate in the representation and management of influencers, as the characterization of this figure is important for the identification of key aspects in the adjustment of products and messages offered to a certain public of a specific population niche, both for advertising companies and for media and institutions.Originality/valueThe study reveals interesting challenges for digital advertising from the audience's perceptions about influencers, highlighting the relevance of influencers which clearly contributes to a better understanding of more efficient strategies on digital advertising.
How emotional regulation and conscientiousness break the reciprocal circle between customer mistreatment and surface acting: an experience sampling study
Authors: Lan Junbang , Gong Yuanyuan , Liu Tao , Wong Man-Nok , Yuan Bocong 
Published: June 2022

Purpose
Drawing on the conservation of resource theory and emotional contagion perspective, this study aims to propose that customer mistreatment has an indirect effect on subsequent customer mistreatment by triggering high levels of surface acting. In other words, there is a vicious circle formed as a result of customer mistreatment and surface acting. This paper further argues that emotional regulation and conscientiousness are effective in breaking this vicious circle.

Design/methodology/approach
An experience sampling study was conducted on 97 frontline service employees in a hotel chain’s restaurants in China, with two daily surveys for ten consecutive days. Multilevel path analyses were used to test the hypotheses.

Findings
The results indicate that employees experiencing customer mistreatment in the morning would adopt the surface acting strategy more frequently in the afternoon, which in turn induces more customer mistreatment in the afternoon. Further, this indirect effect can be mitigated by high (versus low) levels of emotional regulation and conscientiousness.

Originality/value
Recently, there has been growing recognition of the vital links between customer mistreatment and negative employee outcomes. However, these studies have failed to consider the carryover effect of customer mistreatment. To the best of the authors’ knowledge, this is the first pioneer study on whether and how customer mistreatment can affect subsequent instances of customer mistreatment, thereby offering a more comprehensive understanding of the consequences of customer mistreatment.

Authors: Yap Ching Seng , Keling William , Abdullah Shamsul Kamariah 
Published: June 2022

PurposeThis study aims to examine the information acquired and shared by floods victims in Sarawak, Malaysia, and the individuals’ perception of social media information quality and awareness of social media emergency services.Design/methodology/approachThe research data were gathered from 118 victims in two flood-ravaged villages with a researcher-administered questionnaire survey. Meanwhile, the research instrument was adopted from Reuter and Spielhofer (2017).FindingsResultantly, 93% of the respondents employed social media for information-seeking and sharing during floods. For example, Facebook was the most extensively employed digital platform. The most highly sought and exchanged information involved eyewitness pictures or videos, road or traffic conditions and weather conditions or warnings. Although social media information quality reflected faster obtainability, higher accessibility and enriched content, respondents’ viewpoints of social media information quality regarding accuracy and reliability proved negative. Notably, over half of the respondents were unaware of the two social media emergency services: Twitter Alerts and Facebook Safety Check.Originality/valueThis study denoted one of the rare empirical works that explored social media usage for information-seeking and sharing by the flood victims in Sarawak based on the boundary object perspective.
Linking environmental scanning and organizational learning with organizational resilience of Egyptian SMEs: the moderating role of environmental uncertainty
Authors: YahiaMarzouk Yasmine , Jin Jiafei 
Published: June 2022

Purpose
This study aims to examine the impact of environmental scanning on organizational resilience through organizational learning based on organizational information processing theory (OIPT) in Egyptian small and medium-sized enterprises (SMEs) during the COVID-19 pandemic. Furthermore, this study aims to examine the moderating role of environmental uncertainty in this relationship.

Design/methodology/approach
The data for the mediation analysis was obtained using a cross-sectional design. Using a self-administered questionnaire, the authors collected data from a sample of 249 Egyptian SMEs. The authors tested the hypotheses using the smart partial least square structural equation modeling approach.

Findings
Organizational learning affects organizational resilience. Environmental scanning does not have a direct effect on organizational resilience. However, organizational learning fully mediates the relationship between environmental scanning and organizational resilience. Furthermore, environmental uncertainty does not moderate the indirect relationship between environmental scanning and resilience.

Research limitations/implications
The sample included only Egyptian manufacturing SMEs. The results in the service sector and in other countries may differ. This study was cross-sectional, which was limited in its ability to trace the long-term effects of environmental scanning and organizational learning on organizational resilience.

Practical implications
Egyptian SMEs’ managers should experience organizational learning as a pathway for environmental scanning to build organizational resilience.

Originality/value
To the best of the authors’ knowledge, this study is the first to investigate the role of environmental scanning in building organizational resilience through organizational learning and the moderating role of environmental uncertainty in this relationship.
A binding tie: why do customers stick to omnichannel retailers?
Authors: Lin Sheng-Wei , Huang Eugenia Y. , Cheng Kai-Teng 
Published: June 2022

PurposeThis study employed the commitment–trust theory in social psychology and relationship marketing to explore female customers' perception of channel integration quality in omnichannel retailing and its influence on their relationship commitment to and trust in the relationship with retailers, and thus on their stickiness. Channel integration quality consists of two dimensions: channel service configuration (channel choice breadth and channel service transparency) and integrated interactions (content consistency, process consistency and perceived fluency).Design/methodology/approachThe study was carried out via a questionnaire survey, to which 868 valid responses were collected. The partial least squares technique was used to test the hypotheses.FindingsChannel service transparency and perceived fluency influence relationship commitment; content consistency, process consistency and perceived fluency all have significant effects on trust. Interestingly, although less influential than integrated interactions, channel service configuration is the foundation of channel integration quality, testifying to its significant role.Originality/valueThis study provides strong evidence on how channel integration quality affects customer stickiness. Moreover, this study replicates the finding of significant relationships among relationship commitment, trust and stickiness in omnichannel retailing.
Agency costs and auditor choice: moderating role of board’s expertise and internal control
Authors: Behbahaninia Parisa Saadat 
Published: June 2022

Purpose
This study aims to examine the effects of agency cost on auditor choice. This paper also deals with the moderating role of the board’s financial expertise (Bfe) and the status of the internal control (Intecon) system on the relationship between agency cost and auditor selection.

Design/methodology/approach
This study’s sample consists of 1,040 firm-year observations of Iranian nonfinancial companies listed on the Tehran Stock Exchange from 2012 to 2019. The information required for this research is mainly extracted from Comprehensive Database of All Listed Companies (in Iran Stock Exchange). Data from 130 companies were obtained during the research period. This study used logistic regression to test the hypotheses.

Findings
The findings indicate that companies with higher agency costs choose the auditor from lower classes. As the proportion of financial expert members on the board increases, the intensity of this relationship will be reduced. Companies with higher agency costs choose the auditor from the lower classes, but the higher the ratio of financial expert board members, the more these companies will choose high-quality auditors. However, findings showed that the status of the Intecon system has no moderating effect on the relationship between agency costs and auditor selection.

Originality/value
The results of this study can expand the existing literature on the relationship between auditor selection and agency costs and the factors affecting this relationship, especially the Bfe and Intecon. This research has significant suggestions for regulators, stakeholders, shareholders and analysts in emerging economies that may encounter similar contextual implications.
Becoming an “owner” in a learner-centred context: a Sri Lankan experience at a postgraduate taught course in management and technology
Authors: Gunatilaka Hemamalie , Jayawickrama Withanage Dushan 
Published: June 2022

Purpose
There is a need for a shift of the pedagogy to student-centeredness in the teaching–learning process of the higher education sector in countries such as Sri Lanka, where the education system is still identified with the dominant “teacher-centeredness” pedagogy. Within this backdrop, this study aims to understand whether a learner-centred teaching (LCT) can be practised effectively within a postgraduate taught course in Sri Lankan public sector university system.

Design/methodology/approach
Ontologically, this study is placed within the interpretivist paradigm and adopted qualitative methodology. Reflections and experiences of 2 facilitators and 63 participants were thematically analysed.

Findings
Four themes emerged from the data as key phases of LCT-based learning process, namely: “changing role of the facilitators,” “emerging a collaborative learning environment,” “creating a platform for contextualising the knowledge gained in class” and “becoming an owner of the learning.”

Originality/value
Within the learning process, participants became “owners” rather than “renters” because of facilitators maintaining low power distance and participants developing a sense of empowerment, leading to engaging in the learning process willingly. Further, this study shows how the classroom shifted from the state of learner-centred to learner-driven. These novel findings become the main theoretical contribution of this research to existing knowledge.
