Authors: Ugwu Cyprian Ifeanyi , Ejikeme AN
Published: July 2022

The purpose of this study was to investigate the mediating effect of organizational culture on the relationship between knowledge management practices and the job performance of academic librarians in university libraries in Nigeria. The study employed a quantitative research methodology. A total of five hypotheses were proposed for testing, and a conceptual model was developed to test these hypotheses for significance at the .05 level. A questionnaire survey was used and a total of 230 academic librarians agreed to participate in the study. The data collected was analysed with the aid of SPSS. The results of the study reveal that knowledge management and organizational culture made positive and significant contributions to job performance. The results of the study also provide compelling evidence in support of the impact of organizational culture on the relationship between knowledge management and the job performance of academic librarians in university libraries in Nigeria.
Driver Psychology Latent Classes as Predictors of Traffic Incident Occurrence in Naturalistic Driving Study Data
Authors: Sharmin Sadia , Ivan John N. , Marsh Kerry L. , Paxton Alexandra , Tucker Andrew
Published: July 2022

Crash risk depends on several factors, driver factors being the most significant of all. Previous studies have tended to use roadway and driver demographic information to explain crash risk, overlooking driver psychological characteristics, which are also important for crash risk estimation. Crash data from police reports are available only for reportable crashes and do not detail driver characteristics or comparable information on driving activities. Naturalistic driving studies (NDSs) offer unique opportunities to obtain information about driver attributes, behavior, or other precrash factors for predicting crash occurrence. This study estimated NDS event-oriented models to evaluate the interaction between driver attributes and roadway environmental factors for predicting safety critical events. A latent class clustering approach was used to uncover categories of drivers by psychological, perceptual, and cognitive characteristics, and by driving experience. The results revealed four driver types: risk-taker, careful-impaired, careful-unimpaired, and distractible. These types were incorporated in mixed-effects binary logistic models, with roadway, traffic, and environmental variables to estimate and predict crash risk. The models that included driver factors more successfully predicted crash risk than those without. Risk-takers showed the highest probability of being in crashes. However, careful-impaired drivers—those whose impairments made it difficult to identify the location of another vehicle, visualize missing information, who had difficulties with visual–spatial perception and executive functioning—posed a higher crash risk in roadway conditions such as snow, lack of lane markings, and certain traffic operating conditions. The results point to novel avenues for educational and behavioral interventions to improve road safety.
Surgeons’ Survey of the Aging Face With a Focus on the Aging Nose
Authors: Ehland Elise L. , Ali Khan Husain
Published: July 2022

Introduction:

The purpose of this study was to evaluate how facial cosmetic surgeons rank different areas of the aging face by comparing those areas for the greatest impact on surgical rejuvenation. It was hypothesized that the nose would be ranked lower than most other areas of the aging face.

Materials and Methods:

Fifty surveys were included in this study and were completed by surgeons from the following specialties: oral and maxillofacial surgery, oculoplastic surgery, otolaryngology, general surgery, plastic surgery, dermatology, and obstetrics/gynecology. The 12 ranked areas of the face (from 1 to 12) were skin, hair/hairline, brows, periorbital area, nose, ears, cheeks, midface/nasolabial area, dentition, perioral area, lower face/chin/jowls, and neck. Each of these areas of the face was also rated based on the surgeons’ assessment of the level of importance when evaluating and treating the aging face on a 5-level scale, ranging from level 1 (not important) to level 5 (very important).

Results:

The average rank for the nose was 9.30. The highest average ranking was the periorbital region with 2.74 and the lowest average ranking was the ears at 11.02. The surgeons’ ratings of the nose were 0% for level 1 (not important), 20% for level 2 (slightly important), 30% for level 3 (somewhat important), 26% for level 4 (important), and 16% for level 5 (very important). The average level rating of the nose was 3.413 (somewhat important). In comparison, the highest average rating was for the periorbital region at 4.837 (very important) and the lowest average rating was the ears at 2.957 (somewhat important). Using a significance level of P < .05, the nose is both ranked and rated as less important than 7 out of 11 other areas of the face: the periorbital area, the lower face, the skin, the neck, the midface, the perioral area, and the cheeks. The difference between the ranking and rating of the nose and that of the brows, dentition, hairline, and the ears was not considered significant.

Discussion:

This study confirmed the hypothesis that when comparing the areas of the aging face that would have the most effect on surgical facial rejuvenation, the nose was ranked lower than most other areas of the face except the ears. The nose undergoes multiple anatomical changes with age that affect both appearance and nasal function. Therefore, the rhinoplasty for the aging nose should not be overlooked as an important contributor to facial rejuvenation and a potential to improve nasal function.

Conclusion:

The nose is most often considered of lower importance compared with other areas of the face by facial cosmetic surgeons when evaluated for impact on surgical facial rejuvenation.

Published: July 2022

The COVID-19 pandemic produced unprecedented adoption and deployment of technology in rural and northern areas; however, this expansion widened the digital divide for many. Evidence shows that older adults’ use of technology has increased. Coupled with an increasing number of available technologies to enhance healthcare delivery, social engagement, meaningful activities, and support to carers, we are at a crossroads for change. Emerging strategies used by organizations to promote technology and support efforts to bridge and close the digital divide are discussed. In a post-pandemic society, policy-makers can play a critical role to ensure that improvements, efficiency gains, and lessons learned are fully leveraged to reap the benefits of technology use by older adults, care partners, and the healthcare system. Recommendations are given for policy-makers to capitalize on this opportunity to narrow the digital divide for those in rural and northern communities.
Prognostic Implication of Pre-Cannulation Cardiac Arrest in Patients Undergoing Extracorporeal Membrane Oxygenation for the Management of Cardiogenic Shock
Authors: Whiteside Hoyle L. , Hillerson Dustin , Abdel-Latif Ahmed , Gupta Vedant A.
Published: July 2022

Background

The application of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) in contemporary management of cardiogenic shock (CS) has dramatically increased. Despite increased utilization, few predictive models exist to estimate patient survival based on pre-ECMO characteristics. Furthermore, the prognostic implications of pre-ECMO cardiac arrest are not well defined.

Methods

Utilizing an institutional VA-ECMO database, all consecutive patients undergoing VA-ECMO for the management of CS from January 1, 2014, to July 1, 2019, were identified. Survival to hospital discharge was analyzed based on cannulation indication in patients with and without pre-ECMO cardiac arrest. Patients who received extracorporeal cardiopulmonary resuscitation (eCPR) were analyzed separately.

Results

Of the 214 patients identified, 110 did not suffer a cardiac arrest prior to cannulation (cohort 1), 57 patients had a cardiac arrest with sustained ROSC (cohort 2), and 47 were cannulated as a component of eCPR (cohort 3). Despite sustained ROSC (cohort 2), the presence of pre-ECMO cardiac arrest was associated with a significant reduction in survival to hospital discharge (22.8% vs. 55.5% in cohort 1; p < 0.001). Comparatively, survival to discharge was similar in patients undergoing eCPR (22.8% vs. 17.0%; p = 0.464). Finally, patients with a cardiac arrest were significantly more likely to have a neurological etiology death with VA-ECMO than patients supported prior to hemodynamic collapse (18.3% vs. 2.7%; p < 0.001). This result is seen in those with sustained ROSC (21.1% vs. 2.7%; p < 0.001) and those with eCPR (14.9% vs. 2.7%; p = 0.004).

Conclusion

In our cohort, pre-ECMO cardiac arrest carries a negative prognostic value across all indications and is associated with an increased prevalence of neurological-etiology death. This finding is true in patients with sustained ROSC as well as those resuscitated with eCPR. Cardiac arrest can inform survival probability with VA-ECMO as early implementation of VA-ECMO may mitigate adverse outcomes in patients at the highest risk of hemodynamic collapse.
Carbon dots with intrinsic theranostic properties for photodynamic therapy of oral squamous cell carcinoma
Authors: Kong Tingting , Liu Tongjun , Zhang Yujun , Wang Mingguo
Published: July 2022

Carbon dots (CDs) are one of the carbon-based materials with remarkable optical properties, good water dispersibility and high biocompatibility. However, few studies have emphasized the intrinsic photodynamic and anticancer properties of CDs. Herein, we used CDs as photosensitizers to explore their photodynamic therapy (PDT) effect on oral squamous cell carcinoma (OSCC) cells. The obtained CDs had an effective cellular internalization capacity and possessed good biocompatibility in both CAL-27 and UM1 cells. After irradiation, the CDs showed obvious photodynamic effects on the test cells, which were confirmed by apoptosis analysis. In addition, the CDs exhibited excellent intracellular ROS generation under irradiation, and the subsequent induced cell death may be related to a lysosome-associated pathway.

Published: July 2022

The 3D printed porous titanium alloy scaffolds are beneficial to enhance angiogenesis, osteoblast adhesion, and promote osseointegration. However, titanium alloys are biologically inert, which makes the bond between the implant and bone tissue weak and prone to loosening. Inspired by the natural biological marine mussels, we designed four-claw-shaped mussel-derived bioactive peptides for the decoration of porous titanium alloy scaffolds: adhesion peptide-DOPA, anchoring peptide-RGD and osteogenic-inducing peptide-BMP-2. And the bifunctionalization of 3D-printed porous titanium alloy scaffolds was evaluated in vivo in a rabbit model of bone defect with excellent promotion of osseointegration and mechanical stability. Our results show that the in vivo osseointegration ability of the modified 3D printed porous titanium alloy test piece is significantly improved, and the bifunctional polypeptide coating group E has the strongest osseointegration ability. In conclusion, our experimental design partially solves the problems of stress shielding effect and biological inertness, and provides a convenient and feasible method for the clinical application of titanium alloy implants in biomedical implant materials.

Authors: Arlinghaus Katherine R. , Schroeder Mary , Gold Abby , Goodman Lenora P. , Wagner Gerit , Pass Molly , Hunt Shanda , Stang Jamie
Published: July 2022

Objective

Recognition programs are designed to incentivize early care and education (ECE) settings to implement childhood obesity prevention standards, yet little is known regarding their efficacy. This scoping review details characteristics, methodologies, and criteria used to evaluate recognition programs, identifies gaps in evaluation, and synthesizes existing evidence.

Data Source

A public health librarian created the search strategies for six databases: Ovid MEDLINE, AGRICOLA, CAB Abstracts, PAIS Index, ERIC, and Scopus.

Study Inclusion and Exclusion Criteria

Inclusion criteria include recognition program, ECE setting, nutrition or physical activity, and qualitative or quantitative outcomes. Exclusion criteria include programming without recognition component, no ECE setting, no nutrition or physical activity outcome, case studies, or not written in English.

Data Extraction

Three researchers independently extracted and complied data into an Excel spreadsheet.

Data Synthesis

Tables were created describing location, recognition program criteria, award incentive, study design, study sample, risk of bias, and outcomes (e.g., menu nutrition) evaluated in each study.

Results

Three unique recognition programs (described in 7 studies) provided technical assistance, incentives, and training. While outcome measures and study designs varied across programs, it is clear that recognition programs are well accepted and feasible, and one study demonstrated beneficial weight outcomes.

Conclusion

Although additional evaluation is needed, recognition programs may be a promising strategy to improve obesity prevention practices in ECE.
Empirical modeling and optimization of kerf characteristics in Nd-YAG laser cutting of Al 6061-T6 sheet
Authors: Sharma Amit , Joshi Priyanka , Saxena Kuldeep K
Published: July 2022

Al alloys are the second most useful metal worldwide after the steel due to its high strength-to-weight ratio and corrosion resistance properties. In the present scenario, for creating contours in the sheet metals with close tolerances and high precision, laser beam cutting is preferred. During laser beam cutting of Al alloys, the reflectivity of the alloy possesses some difficulties to absorb the laser light. Such problems can be avoided using the shorter wavelength laser. This paper presents the modeling and optimization of kerf characteristics in Nd-YAG laser cutting of Al 6061-T6 sheet. In this study, kerf width (top and bottom side) and top kerf deviation are considered as kerf characteristics which are the functions of lamp current, pulse width, pulse frequency, and cutting speed. Box–Behnken design has been used for conducting the experiments and the experimental results have been further used for developing the response surface models and optimizing the responses using response surface methodology and grey relational analysis, respectively. Application of grey relational analysis has reduced the bottom kerf width by 12.5% and 7.75% along with straight and curved cut profiles respectively.
Aero-engine on-board model based on big Quick Access Recorder data
Authors: Ren Li-Hua , Ye Zhi-Feng , Zhu Ye , Xu Zhan-Yan , Zhao Yong-Ping
Published: July 2022

With the development of the Full Authority Digital Engine Controller (FADEC) technology, the aero-engine on-board model is widely used in Engine Health Management (EHM) and control. Due to the FADEC’s limited computational capability and storage capacity, the model should not be very intricate; consequently, the interpolation model is widely utilized. Although the interpolation model’s low precision precludes further development of on-board models for EHM and control. To address the trade-off between precision and complexity, a novel on-board modeling method is proposed based on the Nonlinear Autoregressive with Exogenous Inputs Backpropagation neural network (NARX-BPNN) trained using the mini-batch Levenberg–Marquardt (LM) algorithm on large Quick Access Recorder (QAR) data. The NARX model’s features and time delay are chosen by referring to the line interpolation model, which gives interpretability for feature selection. The combination of a shallow neural network and big data training can guarantee the on-board model’s real-time and storage requirements, as well as its generalizability. The mini-batch LM method can avoid both the local optimum problem in the shallow neural network and the storage difficulty associated with massive data while still achieving a rapid convergence rate due to the LM algorithm’s global view. The NARX-BPNN models are compared to an existing line interpolation model using 100 different aero-engines' QAR data. The results reveal that accuracy may be increased by approximately 30% while maintaining superior dynamic performance and anti-noise capacity compared to the line interpolation approach.
Green innovation and environmental sustainability: Do clean energy investment and education matter?
Authors: Li Liang , Li Gang , Ozturk Ilhan , Ullah Sana
Published: July 2022

Rapid modernization and industrialization have significantly intensified carbon emissions and worsened environmental sustainability around the globe. Despite the significant importance of green innovation, clean energy consumption, and education in every aspect of life, the role of all these variables in determining environmental sustainability has not been explored quite extensively in case of China. Under this premise, the present study aims to investigate the role of green innovation, clean energy investment, and education on environmental sustainability in highly polluted Asian economies for the period of 1991–2019 by employing the autoregressive distributed lag (ARDL) model. The findings infer that increase in green innovation reduces CO2 emissions in China, India, and Japan in the long-run. However, an increase in clean energy investment and education tends to decline CO2 emissions in Russia and Japan. The findings confirm that green innovation, clean energy investment, and education improve environmental sustainability in long-run, while short-run estimates are diverse. Thus, governments of highly polluted economies should increase investment in education, clean energy, and technology to mitigate CO2 emissions.

Authors: Farhan Mohammed , Rani Prathvi , Moledina Fatimazahra , George Thomas , Tummala Hari Prabhath , Mallayasamy Surulivelrajan
Published: July 2022

Objectives

To build a lamotrigine (LTG) physiologically based pharmacokinetic (PBPK) model (LTG PBPK) and compare it to the clinical data from South Asian Indian patients and use this model to understand the drug interactions of LTG and explore the optimal doses.

Methods and Material

The PBPK model was developed using the PK-Sim software platform and qualified with LTG plasma concentration data from an Indian study. The European population database was chosen as the patient setting in the software. Physiochemical data of LTG and enzyme kinetic data were incorporated from the literature. Dosing protocols were as per the previous study. Interaction models for drug interactions with carbamazepine and valproate were also simulated.

Results

Most of the model predicted concentration-time profiles of LTG at steady-state were well within the observed concentrations. The developed models were suitably qualified. The drug interaction model was used to assess the impact of induction and inhibition of the pharmacokinetic profile of LTG.

Conclusions

The predicted plasma concentrations of the developed PBPK models using the European population database were very similar to the data from Indian patients. The developed LTG PBPK models are applicable in predicting the impact of drug interactions and can yield appropriate LTG doses to be administered.

Published: July 2022

This study aimed at identifying the interplay between individual and organizational factors and predictors of work motivation, job satisfaction, and burnout. This was a cross-sectional study, conducted with 460 early education teachers in Kosovo. Based on the results, job satisfaction and professional development are significant positive predictors whereas burnout is a significant negative predictor of work motivation. Conversely, burnout is a significant negative predictor of job satisfaction, whereas work motivation, job satisfaction, and professional development are significant negative predictors of burnout. The findings provide useful insights which can help policy makers take necessary action to ensure improving early education quality.
Factors Affecting Request & Receipt of I-deals: An Investigation in the Context of Older Workers
Authors: Sykes-Bridge Imogen , Bordia Prashant , Garcia Patrick Raymund James M. , Amarnani Rajiv K. , Bordia Sarbari
Published: July 2022

I-deals are a key method for organizations to retain and motivate employees, yet little research has investigated employee motivations for seeking i-deals and antecedents to request and receipt. We examine these largely invisible antecedents of i-deals in the context of older workers, a cohort of increasing importance in the workplace. Through thematic analysis of 82 in-depth interviews with Australian workers over the age of 50, we develop a model of i-deal emergence that delineates the motivation, request, and receipt stages of i-deals. We identified four motivational influences to seek i-deals: to improve work–life balance, to repair psychological contract breach, and to craft satisfactory retirement pathways; high levels of existing job-role autonomy acted as a demotivator to request i-deals. We also identified three factors associated with an i-deal request being granted: an older worker’s value to the organization, positive employee–manager relationships, and emphasis of mutual benefit for employee and employer. We identified a novel antecedent for i-deals: feasibility—an older worker’s perception of how likely they are to be successful when requesting a desired i-deal. Feasibility perceptions are informed by organizational practices and policies around i-deals, co-worker i-deal experiences, and job-role constraints. Feasibility can influence an employee’s decisions to request an i-deal and also directly affect attitudes toward the employer, regardless of whether an i-deal is present, desired, or otherwise. Theoretical and practical implications are discussed and future directions outlined.

Authors: Howard Theodore , Reichert Ines , Giddie Jasdeep , Ahluwalia Raju
Published: July 2022

Background:

Revision surgery in the presence of infection carries high risks. We describe our results using a new technique to treat these challenging problems. We treated infected nonunions with cavitary voids with adjuvant antibiotic loaded calcium sulfate–hydroxyapatite paste composite and autologous bone graft (ABG) layer technique coupled with stable fixation.

Methods:

Thirty consecutive patients who underwent revision foot and ankle surgery for an infected nonunion were prospectively studied. Following multidisciplinary team workup, surgical debridement and biopsies were undertaken. Bone voids were measured and classified according to containment and size. ABG was mixed and layered with an adjuvant antibiotic-loaded calcium sulfate–hydroxyapatite paste followed by surgical reconstruction including arthrodesis and fixation. Empirical and pathogen-specific antibiotics were instituted until intraoperative sample-specific antibiotics were identified and used. Patients were prospectively followed up for a minimum of 1 year.

Results:

The male-female ratio was 16:14, mean age was 51.3 years, and 23.3% smoked at definitive surgery. Void volume was <1 cm3 (n=9), 1-2 cm3 (n = 13), and >2 cm3 (n=8). No patients either were lost to follow-up or had a further infective episode at a mean of 38.3 months; 86.7% united with fusion on imaging. Four patients had radiographic evidence of nonunion; 3 were asymptomatic and 1 required revision surgery (void >2 cm3). Independent ambulation was achieved at an average of 12 weeks, at 1 year mean American Orthopaedic Foot & Ankle Society score was 77.7 (SD 9.59), and the Manchester-Oxford Foot Questionnaire reached an effect size >0.5 in all domains at 1 year following surgery. The union rate was independent of smoking status and vitamin D deficiency ( P = .94).

Conclusion:

Layered autologous bone grafting with adjuvant antibiotic-loaded calcium sulfate–hydroxyapatite paste has been shown to be effective and safe in revision arthrodesis, with low comorbidities in void gaps without infection recurrence.
Cutting the Bunk: Comparing the Solo and Aggregate Effects of Prebunking and Debunking Covid-19 Vaccine Misinformation
Authors: Amazeen Michelle A. , Krishna Arunima , Eschmann Rob
Published: July 2022

An online experiment among a nationally representative YouGov sample of unvaccinated U.S. adults ( N = 540) leverages inoculation theory as a preliminary step in uniting the prebunking and debunking literature. By testing how prior attitudes toward Covid-19 vaccines interact with varying message interventions, the study finds that specific inoculation messages protect against misinformation, but only among those with preexisting healthy attitudes. Generic inoculation messages have wider application, offering both prophylactic and therapeutic benefits. However, the therapeutic benefits of generic inoculations disappear when debunking messages are present. Nonetheless, generic inoculations do not appear to have detrimental effects on those infected with unhealthy attitudes, unlike specific inoculation messages. Whether the messages are truly a form of inoculation by generating threat merits further research.
“They Killin’ Us for No Reason”: Black Lives Matter, Police Brutality, and Hip-Hop Music—A Quantitative Content Analysis
Authors: Mozie Dante
Published: July 2022

A quantitative content analysis of rap lyrics released after the 2020 death of George Floyd ( n = 66) was conducted to examine the dominant emotions of artists who use their songs to address police brutality and other forms of racism. A large, negative, and statistically significant correlation between negative emotions toward the police and a desire for retaliation was found. This finding may lend support for the African American Offending Theory, which is explained in this study. The rap songs examined could also be seen as a form of alternative commentary not found in news coverage of the 2020 protests.
Toward a (“Dissolved”) Psychology of Interdisciplinary and Transdisciplinary Relations: A Complexity-Informed Proposal
Authors: Teixeira de Melo Ana
Published: July 2022

Our world is in a state of critical transition demanding new, creative, ecosystemically fit and sustainable responses to complex challenges. We need both new types of knowledge and new modes of knowledge production. Interdisciplinarity and Transdisciplinarity have the potential to support more congruently complex forms of knowledge (differentiated, integrated, recursive, emergent, ecosystemically fit). Their success is dependent on a deeper understanding of their own organizational complexity. In this paper, I highlight key knowledge gaps and research questions for the development of a richer knowledge base to guide the intentional management and facilitation of Interdisciplinarity and Transdisciplinary Relations toward creative and abductive outcomes. I defend the investigation of creativity and abduction, as hallmarks of the complexity of Interdisciplinarity and Transdisciplinarity, from a process, relational and complexity-informed perspective, mobilizing contributions from Psychology. I discuss Psychology’s modes of engagement with Interdisciplinarity and Transdisciplinarity in addressing complex challenges. In this context, I introduce the notion of “dissolution” as an Interdisciplinary and Transdisciplinary relational process supporting the theoretical, methodological and pragmatic enrichment or transformation and increased complexity of different disciplines, bodies of knowledge or modes of knowing. Finally, I propose a new domain for research and practice: a (“Dissolved”) Psychology of Interdisciplinary and Transdisciplinary Relations.
Do Handwritten Notes Benefit Online Retailers? A Field Experiment
Authors: Kim Sanghwa , Choi Jeonghye , Kim Seung Hyun
Published: July 2022

Despite the technological advances in online retailing, the human touch continues to be essential to relationships between retailers and customers. Although a handwritten note is proposed as a simple means to help establish a personal relationship, its economic significance and alignment with current practices have been insufficiently studied. In this article, the authors evaluate the benefits of a handwritten note for an online retailer and reveal the boundary conditions of its benefits. A randomized field experiment demonstrates that presenting a handwritten note has a positive and significant effect on customer spending. More importantly, the authors observe that an additional marketing incentive (i.e., giveaway, price discount) attenuates this beneficial effect. Further, the study shows that these two effects arise with loyal customers, but not with nonloyal customers. A follow-up experiment reveals that warmth underlies the key findings, lending support for the theoretical prediction. The article concludes with a general discussion that the authors hope will inspire future research on relationship management in online retailing.
Greenwashing in workplace: The influencing mechanism of psychological contract fulfillment and the moderating role of ethical work climate
Authors: Zhao Hairong , Xu Yan , Wang Xinrui
Published: July 2022

Although green strategies are advocated, not all organizations follow the environmentally friendly rules as they claim. The term of greenwashing is applied to organizations that exaggerate their efforts in protecting the environment and provide misleading information about the greenness of their service. Employees may undertake unethical pro-organizational behaviors (e.g., greenwashing), when they are equipped with less environmentally friendly products. This investigation explores the mechanism of psychological contract fulfillment affecting greenwashing behavior in the hospitality context. We use a mixed-method approach and conduct two studies by collecting both quantitative and qualitative data. Findings suggest that psychological contract fulfillment increases the level of greenwashing behavior, with moral disengagement playing a mediating role. Further, an ethical climate moderates the relation between psychological contract fulfillment and moral disengagement; specifically, when employees work in a team with a high-level ethical climate, the positive relation between psychological contract fulfillment and moral disengagement is weakened. This research deepens the existing insight into the mechanism of influencing service workers’ greenwashing behaviors.
Meta-analytically linking the marketing mix to hospitality organizations’ performance
Authors: Lim SangGon (Edward) , Ok Chihyung (Michael)
Published: July 2022

The body of work investigating marketing and strategic initiatives based on the marketing mix to enhance hospitality organizations’ performance has grown considerably over the last few decades. However, the literature has returned mixed findings that call into question the theoretical and practical effectiveness of the marketing mix. This study meta-analytically examines associations between multiple variables from the marketing mix and hospitality organizations’ performance through a synthesis of 185 relationships across 72 studies. The most impactful predictors were marketing expenses, franchising, and internationalization (objective measures), and quality control, strategic alliances, and market orientation (subjective measures). Marketing trends were also considered by assessing the moderating role of publication year in the respective relationships of brand image, internationalization, franchising, marketing expenses, and strategic alliances with performance. The identified antecedents offer insight into how hospitality managers strategically allocate organizational resources. Results offer compelling evidence for the hospitality marketing and strategic management literature.
The effects of loading direction on the compression after impact strength of quasi-isotropic face sheet honeycomb core sandwich structure
Authors: Nettles Alan T , Guin William E , Sadowski Isabelle
Published: July 2022

This study presents experimental results of compression after impact (CAI) testing of aluminum honeycomb core sandwich structure with face sheets made of quasi-isotropic carbon/epoxy with two orthogonal directions of testing. In a previous study examining the CAI strength of honeycomb sandwich structure,1 it was found that that specimens had different CAI strengths depending on whether the core was oriented in the “L” or “W” direction. Since the face sheets were quasi-isotropic and the core should not (theoretically) affect the CAI strength for a given amount of damage (if the specimens fail by face sheet failure), this result was puzzling. In the study presented in this paper, further CAI tests, along with open hole compression testing were used in an attempt to ferret out the cause of the differing CAI strengths in the aforementioned study. The results showed that the lower CAI strength values were not due to the core orientation, but to the change in the quasi-isotropic face sheet ply sequence due to the 90° rotation.

Published: July 2022

Background:

Serum stem cell factor is elevated in end-stage renal disease (ESRD) patients. This study aimed to investigate the expression of the c-kit receptor, which is the specific membrane receptor of stem cell factor, in failed autologous arteriovenous fistulas (AVFs) in end-stage renal disease patients.

Methods:

A total of 14 ESRD patients with initial AVFs creation and 16 ESRD patients with reconstruction were enrolled in this study. Hematoxylin and eosin (H&E) and elastic Verhoeff-Van Gieson (EVG) staining were used for histomorphometric analyses. Immunohistochemistry was used to examine the expression of c-kit in the intima, and a correlation analysis was performed with the intimal area and the percentage of area stenosis. A double-label immunofluorescence method was used to explore the colocalization of c-kit with α-smooth muscle actin (α-SMA) and CD31. The expression of c-kit and the related PI3K/Akt signaling axis, including PI3K, P-PI3K, Akt, P-Akt473, P-Akt308, and mTOR, was measured by western blotting.

Results:

Internal elastic lamina (IEL) area, intimal area, percentage of area stenosis, and average optical density (AOD) of c-kit in the intima were significantly higher in the failed group than in the preoperative group ( p ⩽ 0.001). The AOD of c-kit in the intima was positively correlated with the intimal area and the percentage of stenosis (intimal area: R = 0.744, p < 0.001; the percentage of stenosis: R = 0.923, p < 0.001). C-kit colocalized with α-SMA but not with CD31 in studies of c-kit target cells. Moreover, the levels of c-kit and P-PI3K, P-Akt473 and mTOR in the PI3K/Akt axis were also higher in the failed group than in the initial group ( p < 0.05).

Conclusions:

C-kit and related proteins associated with the PI3K/Akt pathway were elevated in failed AVFs among ESRD patients and that the expression level of c-kit in the intima correlates with the degree of AVF stenosis.
BioAlign: An Accurate Global PPI Network Alignment Algorithm
Authors: Ayub Umair , Naveed Hammad
Published: July 2022

Motivation:

The advancement of high-throughput PPI profiling techniques results in generating a large amount of PPI data. The alignment of the PPI networks uncovers the relationship between the species that can help understand the biological systems. The comparative study reveals the conserved biological interactions of the proteins across the species. It can also help study the biological pathways and signal networks of the cells. Although several network alignment algorithms are developed to study and compare the PPI data, the development of the aligner that aligns the PPI networks with high biological similarity and coverage is still challenging.

Results:

This paper presents a novel global network alignment algorithm, BioAlign, that incorporates a significant amount of biological information. Existing studies use global sequence and/or 3D-structure similarity to align the PPI networks. In contrast, BioAlign uses the local sequence similarity, predicted secondary structure motifs, and remote homology in addition to global sequence and 3D-structure similarity. The extra sources of biological information help BioAlign to align the proteins with high biological similarity. BioAlign produces significantly better results in terms of AFS and Coverage (6-32 and 7-34 with respect to MF and BP, respectively) than the existing algorithms.

Evaluation of pitting susceptibility and tribocorrosion behaviors of AISI 304 stainless steel in marine environments
Authors: Alkan Sabri
Published: July 2022

There is an increasing concern over simultaneous wear and corrosion (tribocorrosion) issues that cause the material failure of stainless steel in marine environments. The main objective of this study is to understand the effect of tribocorrosion conditions on pitting susceptibility and synergistic material loss for AISI 304 stainless steel. For this purpose, tribocorrosion tests were conducted in a natural seawater-filled corrosion cell integrated with a tribometer. An alumina ball of 6 mm radius slid against AISI 304 stainless steel plates under 5 N and 7.5 N loads in natural seawater. The cyclic polarization scans were carried out under corrosion and tribocorrosion conditions in the natural seawater by applying different loads. Also, tribocorrosion tests were conducted under anodic (0.3 V), cathodic (−0.5 V) and Open Circuit Potential (OCP) to determine the effect of electrochemical potential on pitting susceptibility and material loss rate. The study revealed that electrochemical potential significantly affects pitting corrosion and material loss, and the material losses increased significantly from the cathodic potential to the anodic potential. Furthermore, the material loss of AISI 304 alloy during tribocorrosion in natural seawater due to corrosion was significantly lower than wear. The wear-corrosion synergism played an essential role in total material loss, confirming that wear and corrosion affect accelerated material loss positively. The material loss of AISI 304 is mainly due to pure mechanical wear and corrosion-induced wear.
Moving from physical literacy to co-existing physical literacies: What is the problem?
Authors: Young Lisa , Alfrey Laura , O’Connor Justen
Published: July 2022

This paper explores how various ideological positions or ‘cosmoses’ associated with physical literacy (PL) have come to be and, in doing so, extends scholarship by examining and presenting PL as a multiplicity of physical literacies. Drawing on Stengers’ notion of ‘cosmopolitics’ and Venturini's ‘cartography of controversies’ method, 167 scholarly articles and 23 non-scholarly texts were analysed to observe and describe how PL has been framed over time as a result of dynamic political factors. Findings reveal that three ‘waves’ of PL cosmoses have unfolded over time (PL as health-promoting physical activity, PL as motor competence and PL as phenomenological embodiment). Whilst all three seek to promote engagement in physical activity and have loose ties to ‘health’, each PL cosmos is bound by different objectives, actors and obligations and is orientated towards solving a different problem. Rather than continued confusion and controversy, we propose that PL be understood as a multiverse wherein the three different PL cosmoses are held apart as physical literacies that play co-existing roles based on the problem that each cosmos is trying to solve. While understanding PL as a multiverse is not a solution to the controversy and uncertainty surrounding PL, it provides those who are interested in or tasked with enacting PL an opportunity to become aware of and understand what the different PL cosmoses or physical literacies constitute and thus make possible (or not) on the basis of their ontological differences.

Authors: Hauch Didde , Fjorback Lone Overby , Juul Lise
Published: July 2022

Aim:

The aims of this this study was to examine the psychometric properties, including internal consistency and construct validity, of the Short Warwick-Edinburgh Mental Well-Being Scale (SWEMWBS) in a sample of Danish schoolchildren aged 10–16 years.

Method:

A total of 1155 schoolchildren (54% girls) aged 10–16 years ( Mage=12 years, SD=1.3) responded to an electronic questionnaire as part of the Danish SELFCARE study. To examine the internal consistency and construct validity of the SWEMWBS, we performed descriptive statistics, reliability and correlation analyses in Stata as well as confirmatory factor analysis (CFA) in Mplus. Correlations between scores on the SWEMWBS and scores on scales from the Strengths and Difficulties Questionnaire (SDQ) were calculated using Spearman’s rank correlation coefficients. The analysis was conducted on the general study population and in subgroups divided by sex and class (age groups).

Results:

CFA confirmed SWEMWBS one-dimensional factor structure, and the model fit the data well (CFI=0.984, TLI=0.97, RMSEA=0.062 and SRMR=0.021). The scale showed satisfactory internal consistency (ɑ=0.78) and composite reliability (ω=0.82). In addition, the scale was shown to have acceptable construct validity. Thus, correlations between scores on the SWEMWBS and SDQ subscales were in line with expectations. Corresponding results were found for subgroups divided by sex and class (age groups).

Conclusions:

Our study indicates that the Danish translation of the SWEMWBS is valid for measuring well-being among Danish schoolchildren aged 10–16 years. This construct validation study is among the first to validate the SWEMWBS in younger populations.
Organising family and business: Affective value prioritisation amongst older entrepreneurs
Authors: Stirzaker Rebecca , Kapasi Isla , Galloway Laura
Published: July 2022

This paper explores the entrepreneurial motivations of older entrepreneurs, specifically the importance of affective motivations and the influence of family and personal wellbeing on older entrepreneurs’ decisions to start-up and their subsequent business model choices. Departing from the extant literature examining the effects of family on firm and vice versa, the focus here is on the influence of family outside the boundary of the firm. Drawing on socioemotional selectivity theory (SST), the paper reports a study of older entrepreneurs who report motivations that prioritise family-based affective value external to the enterprise itself. As such, the paper contributes new knowledge on motivations for entrepreneurship and the embedded nature of family and business, particularly for older entrepreneurs.
Onflow and consumption: Affect and first encounters
Authors: Lonergan Paddy , Patterson Maurice , Lichrou Maria
Published: July 2022

In this paper, we are concerned with how we might account for the under-appreciated relation of intensities that flow through and around consumption experiences. In pursuing clarity, researchers have tended to treat consumer experiences as bounded and discrete, segregated from the messy unfolding of life around them. In this work, we look to acknowledge this everyday unfolding of the experience to appreciate how we might articulate the more-than-representational excess of seemingly un-spectacular, quotidian moments of encounter, and how we might attune ourselves to the constant unfolding of consumer experiences. In addressing these concerns, we produce a series of narratives designed to reveal both the ecologies and processual registers of experience. These narratives seek not just to inform, but also to evoke and provoke. Moreover, they work to engage readers with the messiness of everyday life attempting to give form to phenomena that are essentially formless and in continuous circulation.
Storytelling otherwise: Decolonising storytelling in planning
Authors: Ortiz Catalina
Published: July 2022

This article argues that the role of storytelling in planning needs to be rethought learning from the decolonial turn in social sciences. I ask how to decolonise storytelling in planning theory and practice. The aim is to explore how key notions from Latin American decolonial thinking, such as pluriverse, epistemological disobedience, border thinking and sentipensar, can help us to reframe storytelling in planning. This reframing can contribute to finding different avenues to build ontological relationality in a framework of epistemological justice and healing to bring about new imaginations for shaping urban planning otherwise.
Presidential Approval, Tolerant Attitudes, and Economic Performance: The Case of Latin America
Authors: Sendra Mariana , Bohigues Asbel
Published: July 2022

Due to the historical centrality of presidents in Latin America, we argue that presidential approval can be a source of group membership among citizens, creating a division between “ingroups” and “outgroups.” We test the effects of such division on tolerant attitudes toward the rights of system critics to participate in political life in four ways (from the least to the most threatening for the ingroup): voting, giving speeches on television, running for office, and demonstrating peacefully. We further argue that this effect is conditioned by the economic context, and that the ingroup/outgroup divide is activated when an economy performs poorly. Analysis of the AmericasBarometer 2018/2019 survey is consistent with our expectations. Specifically, our results suggest that the main predictor for tolerant attitudes is presidential approval, and that the individual-level effect dissipates in a context of good performance of the economy, which causes the presidential ingroup to not feel threatened by any outgroup.
