Authors: Chaganty Saisunder Shashank , Meril G Rex , Sundass Avinash , James Deeptiman
Published: June 2021

Introduction: Better understanding of disruption of bony and ligamentous constraints of the radiocapitellar joint in complex capitellum fracture is essential for optimizing the surgical care and outcome. This report highlights the need for modification in surgical fixation technique to address an unusual variant of this rare injury.
Case Report: We report a three-part capitellum fracture pattern with a Y-shaped split of distal humerus with a sheared anterior fragment and a single, large, non-articular posterolateral fragment in a young male patient. Articular fragment was fixed with two countersunk anterior-distal to posterior-proximal oblique screws. Additional screw was used to fix the posterolateral fragment to prevent posterolateral rotational instability. Mayo elbow performance score was 95 with no rotational instability at 2 years follow-up.
Conclusion: Additional fixation of posterolateral fragment in this three-part variant of Bryan and Morrey Type IV capitellum fracture ensured rotational stability and good function.
Keywords: Complex capitellum fracture, anterior-posterior fixation, elbow posterolateral rotatory instability, posterolateral capitellum fracture.

Published: June 2021

Introduction: Severe open injuries of limbs, especially of the femur and tibia when associated with vascular injuries, present major challenges in management. The decision to amputate or salvage can often be a difficult one even for experienced surgeons. Mangled lower extremity results due to high-energy trauma, especially due to motor vehicle accidents, and is defined as injury to three of the four systems in the extremity that is soft tissues, bone, vascular, and nerve. Open fractures are classified by Gustilo and Anderson’s classification in which type 3B is an injury where soft-tissue loss and primary closure of the wound are not possible and type 3C is any open fracture with vascular compromise.
Case Report: We report a series of six ipsilateral fractures of the femur and the tibia treated at the Department of Orthopaedics, Sri Ramachandra Medical College and Hospital, Chennai, Tamil Nadu, over a 3-year period (2014–2017). The mean age of our patients was 30 years old, and there were five men and one woman. The right side lower limb was frequently involved (five cases), and the main etiology was road traffic accidents (six cases). Articular involvement was found in six cases. Skin wounds were noticed in all cases (type III C of the Gustilo classification). Urgent wound care, fluid replacement, and antibiotic therapy were undertaken for open fractures. According to modified Fraser classification, all six cases was classified under type II-C. Mangled extremity severity score for five cases was 7 and for one case it was 8. Ganga Hospital Open Injury Severity Score was also used which was found to be in borderline range of 16 score for three cases, 15 score for two cases, and 14 score for one case. All six cases were managed with serial wound debridement + Ilizarov fixator + soft-tissue repair with involvement of orthopedic, vascular, and plastic surgery team. Limb salvage was done for all six cases after considering all the factors. Postoperatively, rehabilitative
Capacity of underwater optical wireless communication systems over salinity-induced oceanic turbulence channels with ISI
Authors: Boluda-Ruiz Rubén , Salcedo-Serrano Pedro , Castillo-Vázquez Beatriz , García-Zambrana Antonio , Garrido-Balsells José María
Published: June 2021

Point-to-point underwater optical wireless communication (UOWC) links are mainly impaired by scattering due to impurities and turbidity in the open water, resulting in a significant inter-symbol interference (ISI) that limits seriously both channel capacity and the maximum practical information rate. This paper conducts, for the first time, the channel capacity analysis of UOWC systems in the presence of ISI and salinity-induced oceanic turbulence when the undersea optical channel is accurately modeled by linear discrete-time filtering of the input symbols. In this way, novel upper and lower bounds on channel capacity and mutual information are developed for non-uniform on-off keying (OOK) modulation when different constraints are imposed on the channel input. The results show that the capacity-achieving distribution, which is computed through numerical optimization, is discrete and depends on the optical signal-to-noise-ratio (SNR). Moreover, a non-uniform input distribution significantly improves the channel capacity of such systems affected by ISI and oceanic turbulence, especially at low optical SNR. Monte Carlo techniques are employed to test the developed bounds for different undersea optical channels with one, two and three casual ISI coefficients.

Background

Buruli ulcer disease (BUD) results in disabilities and deformities in the absence of early medical intervention. The extensive role of caregiving in BUD is widely acknowledged, however, associated caregiver burden is poorly understood. In this paper we assessed the burden which caregivers experience when supporting patients with BUD in Ghana.

Method/ principal findings

This qualitative study was conducted in 3 districts in Ghana between August and October 2019. 13 semi-structured interviews were conducted on caregivers of BUD patients in the local language of Twi. Data was translated into English, coded into broad themes, and direct content analysis approach was used to analyse results. The results show the caregivers face financial, psychological and health issues as a consequence of their caregiving role.

Conclusion/ significance

This study found significant caregiver burden on family members. It also highlighted the psychological burden caregivers experience and the limited knowledge of the disease within endemic communities. Further research is needed to quantify the caregiver burden of BUD at different economic levels in order to better understand the impact of possible caregiver interventions on patient outcomes.

Savannah tsetse flies avoid flying toward tsetse fly-refractory waterbuck (Kobus defassa) mediated by a repellent blend of volatile compounds in their body odor comprised of δ-octalactone, geranyl acetone, phenols (guaiacol and carvacrol), and homologues of carboxylic acids (C5-C10) and 2-alkanones (C8-C13). However, although the blends of carboxylic acids and that of 2-alkanones contributed incrementally to the repellency of the waterbuck odor to savannah tsetse flies, some waterbuck constituents (particularly, nonanoic acid and 2-nonanone) showed significant attractive properties. In another study, increasing the ring size of δ-octalactone from six to seven membered ring changed the activity of the resulting molecule (ε-nonalactone) on the savannah tsetse flies from repellency to attraction. In the present study, we first compared the effect of blending ε-nonalactone, nonanoic acid and 2-nonanone in 1:1 binary and 1:1:1 ternary combination on responses ofGlossina pallidipesandGlossina morsitans morsitanstsetse flies in a two-choice wind tunnel. The compounds showed clear synergistic effects in the blends, with the ternary blend demonstrating higher attraction than the binary blends and individual compounds. Our follow up laboratory comparisons of tsetse fly responses to ternary combinations with different relative proportions of the three components showed that the blend in 1:3:2 proportion was most attractive relative to fermented cow urine (FCU) to both tsetse species. In our field experiments at Shimba Hills game reserve in Kenya, whereG.pallidipesare dominant, the pattern of tsetse catches we obtained with different proportions of the three compounds were similar to those we observed in the laboratory. Interestingly, the three-component blend in 1:3:2 proportion when released at optimized rate of 13.71mg/h was 235% more attractive toG.pallidipesthan a combination of POCA (3-n-Propylphenol, 1-Octen-3-ol, 4-Cresol, and Acetone) and fermented cattle urine (FCU). This constitutes a novel finding with potential for downstream deployment in bait technologies for more effective control ofG.pallidipes,G.m.morsitans, and perhaps other savannah tsetse fly species, in ‘pull’ and ‘pull-push’ tactics.
How predictability affects habituation to novelty
Authors: Ueda Kazutaka , Sekoguchi Takahiro , Yanagisawa Hideyoshi
Published: June 2021

One becomes accustomed to repeated exposures, even for a novel event. In the present study, we investigated how predictability affects habituation to novelty by applying a mathematical model of arousal that we previously developed, and through the use of psychophysiological experiments to test the model’s prediction. We formalized habituation to novelty as a decrement in Kullback-Leibler divergence from Bayesian prior to posterior (i.e., information gain) representing arousal evoked from a novel event through Bayesian update. The model predicted an interaction effect between initial uncertainty and initial prediction error (i.e., predictability) on habituation to novelty: the greater the initial uncertainty, the faster the decrease in information gain (i.e., the sooner habituation occurs). This prediction was supported by experimental results using subjective reports of surprise and event-related potential (P300) evoked by visual-auditory incongruity. Our findings suggest that in highly uncertain situations, repeated exposure to stimuli can enhance habituation to novel stimuli.
Perceptions of cervical cancer prevention among a group of ethnic minority women in Denmark—A qualitative study
Authors: Badre-Esfahani Sara , Petersen Lone Kjeld , Tatari Camilla Rahr , Blaakær Jan , Andersen Berit , Seibæk Lene
Published: June 2021

Background

Cervical cancer screening (CCS) and human papillomavirus vaccination (HPVV) are effective measures against cervical cancer (CC). Attendance in HPVV and CCS provides the greatest protection, while combined non-attendance in HPVV and CCS provides little to no protection. It is hence concerning that some large ethnic minority groups show considerably lower HPVV and CCS attendance than other women–especially women from Middle-Eastern and North African (MENA) countries and Pakistan. Little is, however, known about the reasons for this low combined attendance pattern n.

Aim

To explore perceptions of and barriers to HPVV and CCS, among MENA and Pakistani women in Denmark.

Method

Focus group interviews were conducted. Data was transcribed verbatim, and analysed using systematic text condensation.

Findings

Seventeen long-term resident women originating from six major MENA countries and Pakistan were included. Mean age was 36 years. We found that these women, across different age groups and descent, had sparse knowledge and understanding about CC, and their perceived relevance of disease prevention was low. Compared to HPVV, their barriers to CCS were more fixed and often linked to socio-cultural factors such as taboos related to female genitals and sexuality. Moreover, they presented unmet expectations and signs of mistrust in the healthcare system. However, at the end of the interviews, participants became more attentive toward CC prevention, particularly toward HPVV.

Conclusion

Elements of insufficient knowledge and understanding of CC and its prevention were found among a group of MENA and Pakistani women. Their socio-cultural background further represents a barrier particularly towards CCS. Additionally, negative experiences and unmet expectations lessen their trust in the healthcare system. All of which underlines the need for new tailored CC preventive strategies for this group. Based on our findings we suggest that future studies develop and evaluate interventions aiming to improve HPVV and CCS, including user-involvement.
Autonomic biomarkers of shock in idiopathic systemic capillary leak syndrome
Authors: Wu Maddalena Alessandra , Catena Emanuele , Castelli Antonio , Rech Roberto , Borghi Beatrice , Ottolina Davide , Fossali Tommaso , Cogliati Chiara , Colombo Riccardo
Published: June 2021

Objective

The term Idiopathic Systemic Capillary Leak Syndrome (ISCLS) refers to an uncommon condition of severe distributive shock, resulting from an abrupt shift of fluids and proteins from the intravascular to the interstitial compartment. We hypothesise that the autonomic nervous system (ANS) fails in regulating the response to hypovolemia in acute ISCLS and that ANS variables characterise the progression to the recovery.

Design

Prospective cohort study of patients admitted to ICU for severe ISCLS flares.

Setting

Single, referral center in Italy for ISCLS.

Patients

Analysis of cardiovascular signals recorded during seven severe ISCLS attacks and one prodromal period in five patients.

Interventions

ANS was studied non-invasively by means of heart rate variability (HRV) and blood pressure variability analysis, as an estimation of vagal and sympathetic modulation directed to the heart and vessels. Heart rate and systolic arterial pressure (SAP) variability were also used to assess baroreflex sensitivity. ANS variables were measured during the subsequent phases which characterise ISCLS flares, namely the acute phase, the post-acute phase, and the recovery phase.

Measurements and main results

HRV was severely depressed during the acute phase accounting for the loss of ANS modulation during massive capillary extravasation. This phase was characterised by shock and impaired baroreflex control, which allowed SAP to oscillate driven by respiratory activity. Impending shock and transition from shock to a post-acute phase were marked by change of baroreflex spectral variables. The baroreflex control was fully restored during recovery.

Conclusions

ANS modulation and baroreflex control are severely impaired during the acute haemodynamic instability which characterises ISCLS crises and their progressive restoration may be a clue of improvement. ANS indices during ISCLS flares might serve as useful biomarkers, able to timely announce the transition from one phase to the subsequent one, thus helping to adapt therapy accordingly.
Estimating societal benefits from Nordic catchments: An integrative approach using a final ecosystem services framework

Published: June 2021

Nordic catchments provide a variety of ecosystem services, from harvestable goods to mitigation of climate change and recreational possibilities. Flows of supplied ecosystem services depend on a broad range of factors, including climate, hydrology, land management and human population density. The aims of this study were: 1) to quantify the total economic value (TEV) of consumed ecosystem services across Nordic catchments, 2) to explain variation in ecosystem service value using socio-geographic and natural factors as explanatory variables in multiple linear regression, and 3) to determine which societal groups benefit from these ecosystem services. Furthermore, we tested the scientific rigour of our framework based on the concept of final ecosystem services (FES). We used a spatially explicit, integrative framework for ecosystem services quantification to compile data on final ecosystem services provision from six catchments across Denmark, Finland, Norway and Sweden. Our estimates showed a broad variation in TEV and in the proportion contributed by separate services, with the highest TEV of €7,199 ± 4,561 ha-1 y-1 (mean ± standard deviation) in the Norwegian Orrevassdraget catchment, and the lowest TEV of €183 ± 517 ha-1 y-1 in the Finnish Simojoki catchment. The value of material services was dependent on both geographic factors and land management practices, while the value of immaterial services was strongly dependent on population density and the availability of water. Using spatial data on land use, forest productivity and population density in a GIS analysis showed where hotspots of ecosystem services supply are located, and where specific stakeholder groups benefit most. We show that our framework is applicable to a broad variety of data sources and across countries, making international comparative analyses possible.
Does cultural distance energize employees? The moderating role of psychological safety
Authors: Yuan Yingjie
Published: June 2021

The increasingly globalized workforce and the growing need for boosting employee energy have engendered both practical and research interest in stimulating employee energy in intercultural interactions. Yet neither the culture research nor the energy literature has explored the link between cultural distance and employee relational energy—the heightened level of psychological resources in social relations. This paper presents empirical evidence of cultural distance stimulating relational energy. Further, building upon the threat-rigidity theory, I propose that cultural distance stimulates relational energy more when employees perceive high levels of psychological safety. Two studies were conducted to test these two hypotheses. One laboratory experiment on 202 international students at a Dutch university provided causal evidence of the positive relationship between cultural distance and relational energy. Next, a two-wave field study on 373 international employees was conducted to replicate this main effect of cultural distance and further investigate the moderating role of psychological safety. Results supported that employees with higher levels of psychological safety are more prone to experience enhanced relational energy as a result of cultural distance. These findings contribute to the scarce research on possible positive influence of cross-cultural communication at work, and also advance the growing research on the antecedents of employee relational energy. The implications for practitioners to energize employees are also discussed.
The impact of COVID-19 on hospital admissions and emergency department visits: A population-based study
Authors: Rennert-May Elissa , Leal Jenine , Thanh Nguyen Xuan , Lang Eddy , Dowling Shawn , Manns Braden , Wasylak Tracy , Ronksley Paul E.
Published: June 2021

Background

As a result of the novel coronavirus disease 2019 (COVID-19), there have been widespread changes in healthcare access. We conducted a retrospective population-based study in Alberta, Canada (population 4.4 million), where there have been approximately 1550 hospital admissions for COVID-19, to determine the impact of COVID-19 on hospital admissions and emergency department (ED visits), following initiation of a public health emergency act on March 15, 2020.

Methods

We used multivariable negative binomial regression models to compare daily numbers of medical/surgical hospital admissions via the ED between March 16-September 23, 2019 (pre COVID-19) and March 16-September 23, 2020 (post COVID-19 public health measures). We compared the most frequent diagnoses for hospital admissions pre/post COVID-19 public health measures. A similar analysis was completed for numbers of daily ED visits for any reason with a particular focus on ambulatory care sensitive conditions (ACSC).

Findings

There was a significant reduction in both daily medical (incident rate ratio (IRR) 0.86, p<0.001) and surgical (IRR 0.82, p<0.001) admissions through the ED in Alberta post COVID-19 public health measures. There was a significant decline in daily ED visits (IRR 0.65, p<0.001) including ACSC (IRR 0.75, p<0.001). The most common medical/surgical diagnoses for hospital admissions did not vary substantially pre and post COVID-19 public health measures, though there was a significant reduction in admissions for chronic obstructive pulmonary disease and a significant increase in admissions for mental and behavioral disorders due to use of alcohol.

Conclusions

Despite a relatively low volume of COVID-19 hospital admissions in Alberta, there was an extensive impact on our healthcare system with fewer admissions to hospital and ED visits. This work generates hypotheses around causes for reduced hospital admissions and ED visits which warrant further investigation. As most publicly funded health systems struggle with health-system capacity routinely, understanding how these reductions can be safely sustained will be critical.
Comparison of intravenous magnesium sulphate and lidocaine for attenuation of cardiovascular response to laryngoscopy and endotracheal intubation in elective surgical patients at Zewditu Memorial Hospital Addis Ababa, Ethiopia
Authors: Misganaw Abebaw , Sitote Mulualem , Jemal Suliman , Melese Eyayalem , Hune Metages , Seyoum Fetene , Sema Alekaw , Bimrew Dagim
Published: June 2021

Background

Laryngoscopy and endotracheal intubation are essential components of general anesthesia. But it is always associated with side effects called reflex cardiovascular responses. Many methods have been identified to attenuate these responses like intravenous lidocaine, deep inhalational anesthesia, vasodilators, intravenous magnesium sulphate even though therapeutic superiority remains understudied.

Methods

An institutional-based cohort study on 112 adult patients aged between 18–60 years was applied. 37 patients in the non-exposed group (Group N), 37 in the lidocaine group (Group L), and 38 in magnesium sulphate (Group M) were included. The hemodynamic parameters like heart rate, systolic, diastolic and mean arterial blood pressure at various time points up to 7 minutes post-intubation were recorded and the effect of both drugs to reduce hemodynamic responses was compared. Parametric data were analyzed using ANOVA and nonparametric data using the Kuruska-Wallis H rank test. P-value < 0.05 considered statistically significant.

Results

In all three groups, there was a statistically significant rise in heart rate and blood pressure from baseline. There was a statistically significant difference in mean heart rate throughout study minutes among the groups (p<0.001). However, there was no statistically significant difference in mean heart rate between Groups M and L at all post-intubation time intervals. In blood pressure at all three parameters there was statistically significant difference among groups at all-time points except no difference at 7th minutes in DBP. There was significantly lower blood pressure in group M compared to both groups.

Conclusion

In conclusion, prophylactic administration of magnesium sulphate and lidocaine was effective in attenuating hemodynamic responses to the stress effect of laryngoscopy and intubation. But based on our finding prophylaxis of magnesium sulphate is associated with a more favorable hemodynamic response.

Human immunodeficiency virus (HIV) vaccines have not been successful in clinical trials. Dimeric IgA (dIgA) in the form of secretory IgA is the most abundant antibody class in mucosal tissues, making dIgA a prime candidate for potential HIV vaccines. We coupled Positron Emission Tomography (PET) imaging and fluorescent microscopy of64Cu-labeled, photoactivatable-GFP HIV (PA-GFP-BaL) and fluorescently labeled dIgA to determine how dIgA antibodies influence virus interaction with mucosal barriers and viral penetration in colorectal tissue. Our results show that HIV virions rapidly disseminate throughout the colon two hours after exposure. The presence of dIgA resulted in an increase in virions and penetration depth in the transverse colon. Moreover, virions were found in the mesenteric lymph nodes two hours after viral exposure, and the presence of dIgA led to an increase in virions in mesenteric lymph nodes. Taken together, these technologies enablein vivoandin situvisualization of antibody-virus interactions and detailed investigations of early events in HIV infection.
Storming off the tracks: Zombies, high speed rail and South Korean identity in Train to Busan
Authors: Gardener Ryan
Published: June 2021

This article focuses on how the recent blockbuster hit Train to Busan (Yeon 2016), in transposing the zombie horror genre into the South Korean setting, allows South Korean history and social context to actively shape the manner in which it appropriates a genre largely untested by the local film industry. It argues that the film uses genre as a global vernacular through which to speak of specifically Korean issues (in particular, the Korean War, and the issues of South Korea’s speed-oriented Ppalli-Ppalli culture), and locates such practice within the broader context of contemporary South Korean cinema.

El marco teórico de esta investigación, a su vez informa a la metodología mediante las sugerencias de varios autores orientadas a promover la participación de las audiencias. Por este motivo, este estudio aplicó la investigación-acción participativa, métodos cualitativos, epistemología decolonial, y un análisis que combina la teoría de los dos pasos, teoría del framing y teoría del médium. Esta metodología se aplicó en el co-diseño de estrategias comunicacionales en dos programas de salud, uno para niños (Estados Unidos) y otro para adolescentes (Ecuador), que promueven hábitos saludables.

 

El co-diseño de este proyecto: (a) facilitó el diálogo entre investigadores y sus audiencias; (b) permitió crear estrategias comunicacionales adaptadas a las audiencias; y (c) se propusieron guías de comunicación científica que evidencian la importancia del involucramiento de los investigadores como voceros del contenido científico, criterios de diseño de mensajes científicos para no-expertos, y criterios para la selección de canales comunicacionales.
La comunicación online de la RSC en materia medioambiental. El caso de las empresas de moda rápida y moda lenta
Authors: García-Huguet Laura
Published: June 2021

La preocupación de la ciudadanía por el impacto medioambiental de sus acciones les ha llevado a replantear sus hábitos de consumo hacia unos más sostenibles con su entorno. Las empresas, como entes sociales y tanto por este motivo como por su impacto medioambiental, social y económico, han de replantear su estrategia de negocio hacia una más sostenible y comprometida con estas tres esferas en un paradigma empresarial en la que la correcta gestión de los intangibles, como la Responsabilidad Social Corporativa, puede inferir en una buena reputación. Sobre todo, en el caso de la moda rápida, que se convierte en una de las más contaminantes del mundo. El presente trabajo pretende analizar las comunicaciones sobre RSC que estas empresas comparten en Facebook y si existe una hegemonía o diferencia entre las comunicaciones de este tipo que realizan las organizaciones de moda lenta, con un modelo de producción y confección totalmente sostenible. De esta investigación se concluye que, a pesar de realizar acciones sostenibles como informan en sus páginas corporativas, las empresas de moda rápida no las comunican en su perfil de Facebook, a diferencia de las de moda lenta que las comunican de forma constante.

‘To work more, produce more and defend the revolution’: Copper workers from socialism to neoliberalism
Authors: Whitaker Georgia , Vergara Ángela
Published: June 2021

On 11 July 1971, Chile’s National Congress, in a historic vote, unanimously approved reforming the constitution, which opened the door to nationalise the large-scale copper industry. Traditional historical accounts of the nationalisation of copper had emphasised a history of negotiations between foreign capital and the Chilean government, documenting how economists and political leaders experimented with different approaches to obtain a share of the profits from the country’s most valuable commodity. By focusing exclusively on the political economy, however, scholars have overlooked the role of workers during and after the process of nationalisation and failed to account for why copper miners continued to fight to protect a state-owned company. Influenced by Peter Winn’s Weavers of Revolution and recent studies on people’s experience during the Popular Unity (UP) era, this article looks at the nationalisation of copper from below. It analyses how workers fought for, understood and experienced the nationalisation; how the UP transformed labour relations at the local level; and how the military, after 1973, redesigned the state company. By placing workers at the centre of the nationalisation, this article can help better understand its importance as a matter of both political economy and workers’ power and explain why the copper mines became the first site of labour resistance against the military regime.
Concluding reflections
Authors: Volk Steven S.
Published: June 2021

In October 2020, Chilean voters resoundingly elected to abandon the constitution left behind by the Pinochet dictatorship. A new charter will be written by a fully elected, gender-balanced, constitutional convention. Given that Chilean political leaders have floated the idea of jettisoning the 1980 constitution for the last 35 years, what accounts for their decisive step at this point? Summarising and reflecting on the contributions to this special issue, I argue that the October 2020 vote was, in a sense, the result of decades of popular resistance, nurtured and informed by rich and tragic historical memories and experiences. The October result demonstrated an understanding of how to mobilise and energise a huge and diverse base of popular support as well a keen awareness of how to prepare for the violence that inevitably was launched against it.
Accuracy of the ultrasound attenuation coefficient for the evaluation of hepatic steatosis: a systematic review and meta-analysis of prospective studies

Published: June 2021

Purpose: The accurate detection and quantification of hepatic steatosis using a noninvasive method are important for the management of nonalcoholic fatty liver disease. We performed a systematic review and meta-analysis of the accuracy of the ultrasound-measured attenuation coefficient (AC) in the evaluation of hepatic steatosis.Methods: The PubMed, Embase, and Cochrane databases were searched for prospective studies reporting the diagnostic accuracy of AC for assessing hepatic steatosis. The meta-analytic pooled sensitivity and specificity of AC for any grade of steatosis (S≥1) and advanced steatosis (S≥2) were estimated using a bivariate random-effects model. Meta-regression analysis was conducted to investigate the causes of heterogeneity among studies.Results: Thirteen studies including 1,509 patients were identified. The pooled sensitivity and specificity of AC for S≥1 were 76% (95% confidence interval [CI], 73% to 80%; I2=43%) and 84% (95% CI, 77% to 89%; I2=74%), respectively, while for S≥2 they were 87% (95% CI, 83% to 91%; I2=0%) and 79% (95% CI, 75% to 83%; I2=59%), respectively. Study heterogeneity was associated with body mass index (BMI) and the prevalence of steatosis or significant fibrosis.Conclusion: AC can be clinically useful for assessing hepatic steatosis, with good overall diagnostic performance. The data reported in the published literature differed according to BMI and the prevalence of steatosis or significant fibrosis, and careful interpretation with consideration of these factors might be needed.

Employee’s commitment is an important work attitude for an organization. Supervisors can play a role in increasing it by conducting downward influence tactics. This study examines the relationship between employee competency and downward influence tactics (consultation, ingratiation, and exchange tactics), the relationship between these tactics and employee’s commitment to the supervisor and the organization, and the mediating effect of these tactics on the relationship between employee competency and employee’s commitment. Data were collected from 203 non-managerial employees who work in various industries in Surabaya, Indonesia. We analyzed the collected data by using PLS-SEM. This study found that employee competency has a significant positive relationship with downward influence tactics (consultation, ingratiation, and exchange tactics). In addition, consultation and ingratiation tactics have a significant relationship with one’s commitment to one’s supervisor, but only consultation tactic has a significant relationship with organizational commitment. The consultation tactic has a mediation effect on the relationship between employee competency and organizational commitment, and the commitment to the supervisor.

This research examines the effect of perceived usefulness, perceived ease of use, trust in the sellers, and perceived sellers’ risk on the intention to repurchase in online marketplaces by respondents from Thailand and Germany. This research also integrates the theoretical framework of cultural values to explore whether these determinants’ effect on the intention to repurchase in online marketplaces differs significantly between the respondents from these two nations. Online survey data were collected from 404 Thai and 405 German participants, and partial least squares structural equation modeling was used for data analysis. The results confirmed the significant effect of perceived usefulness, perceived ease of use, trust in the sellers, and perceived sellers’ risk on the intention to repurchase in online marketplaces. Moreover, the moderating effect analysis showed that the effect of perceived usefulness, perceived ease of use, and trust in the sellers were significantly higher in Thai than in German respondents. However, there was no significant difference between the two nationalities in the effect of perceived sellers’ risk on the intention to repurchase in online marketplaces.

Despite the importance of consumer engagement in social media, the theoretical meaning and dimensionality remain unclear to date. This paper addressed this void by proposing consumer engagement as a multi-dimensional model consisting of cognitive, affective and behavioral dimensions and testing the model along with its antecedents (brand and product involvement) and consequence (brand loyalty) in the context of brand-hosted social media communities in South Korea. This study used a web-based survey method for data collection (N = 364). Results of SEM provided empirical evidence that supports consumer engagement as a three-dimensional construct. Further, both brand involvement and product involvement were found to positively influence all three dimensions of consumer engagement which further contribute to brand loyalty. This study contributes to the social media marketing literature by validating the three-dimensional model of consumer engagement within brand social media communities. Additionally, the results guide marketers to take consumer differences in product and brand involvement into account in facilitating consumer engagement with brand communities on social media.

Published: June 2021

Worldwide, the time spent online and in digital media has been increasing, thus becoming the primary source of health and medical information. This phenomenon is driving all business, including the pharmaceutical industry, in gearing toward digital marketing strategies. Developing countries like Thailand still extend existing laws to regulate digital media despite the differences with traditional media, and consumers face the risks of buying drugs illegally and products that overclaim despite stringent pre-approval regulations on drug marketing. This study utilizes design thinking as a human-centric research method to propose appropriate and practical digital marketing guidelines for the pharmaceutical industry, using 53 informants. The problems were that consumers face persuasive risks and the need for reliable sources of drug information. The current regulatory process places a high burden on regulators and the laws that enforce it. However, several new digital strategies such as unbranded information and targeted marketing are not covered by existing laws. Regulations on teleconsultation are also needed, but no legislation currently exists for such activities. And finally, experts have articulated four domains as follows: eRegulations, e-Information sources, and e-Consultation to provide easy access to professionals, and e-Ethics, a supportive mechanism toward ethical drug marketing

Authors: Rosół Rafał
Published: June 2021

Artykuł przedstawia różne wątki łączące stadiony piłkarskie w Polsce z Zagładą społeczności żydowskiej. Wydaje się prawdopodobne, że sugerowane tematy mogą być wykorzystane do celów edukacyjnych w szkołach lub innych instytucjach. Są to następujące tematy: 1. obóz pracy przymusowej na stadionie w Poznaniu (na podstawie filmu krótkometrażowego Stadion); 2. selekcja Żydów na stadionie w Będzinie (dziennik Rutki Laskier); 3. masowy grób na terenie kompleksu Skry Warszawa (książka Franza Blättlera Warszawa 1942 i film dokumentalny pt. Niedokończony film); 4. cmentarze żydowskie przerobione na boiska piłkarskie (relacja mieszkańca Kleczewa); 5. stadiony dawnych klubów żydowskich dzisiaj (z nawiązaniem do reportażu Maccabi Voices).

Pomoc wykluczonych, czyli o daremności – Zagłada w Śladach Ludwika Heringa
Authors: Przymuszała Beata
Published: June 2021

Artykuł pokazuje sposób przedstawiania Zagłady w opowiadaniach Ludwika Heringa. Skupia się na konstrukcji narratora i bohatera, analizując ich stosunek do sytuacji Żydów. W kontekście przywoływanego w tekstach antysemityzmu protagoniści nie tylko się wobec niego dystansują, ale starają się pomóc Żydom. Zdają sobie jednak przy tym sprawę z ograniczonego charakteru tej pomocy, odsłaniają jej realia. Pomagający Polak, sam społecznie wykluczony, ma świadomość siły społecznych reguł, które samą pomoc niszczą.
