Using Involvement to Enhance Employee Engagement in it Firms: Examining Leadership Initiatives in a Key Developing National Context

Many organisational leaders increasingly use employee involvement to serve their interests, spurred by the unitarist rationale of leader&#8208;member exchange (LMX). Existing research into employee involvement and participation (EIP) management has mainly focused on manufacturing firms in advanced economies and has not kept pace with developments in settings where practice is primarily governed by organisational leaders plus greater use is made of informal and technologically assisted EIP. Consequently, this paper investigates the management of EIP in IT firms at the forefront of these developments in India. The findings reveal how an array of informal initiatives, including social media, are being used to permeate traditional LMX and EIP boundaries to reinforce unitarist leadership goals. Limitations to some of these initiatives are elucidated, as they are unevenly used and contested by employees. Thus, the paper contributes to critiques of LMX as an ancillary framework for EIP.
An Assessment of the Knowledge, Attitude, and Practice of Phone Use While Driving and Crash Outcomes Among Drivers in Oyo State, Nigeria

This study aims to assess the relationship between crash outcomes and the knowledge of mobile phone hazards, attitude towards mobile phone use, and practices of mobile phone use among urban Nigerian drivers. The study used a quantitative cross-sectional analytical design. A total of 377 completed responses were obtained through a self-administered questionnaire. The outcome measures were self-reported crash involvement, self-reported crash injury, and self-reported mobile phonerelated crash involvement. The main predictor variables were the knowledge of mobile phone hazards while driving, attitude towards mobile phone use while driving, and practices of phone use while driving. Age, sex, marital status, level of education, and driving experience were used as potential confounders. Univariate and multivariate logistic regression analyses were used to compute the unadjusted and adjusted odds of each crash outcome. The results show almost 75% of the study population reported that they had been involved in a crash event and sustained crash injuries in the past. Drivers with poor knowledge of mobile phone hazards while driving had significantly elevated odds of self-reported crash outcomes compared to those with good knowledge of mobile phone hazards while driving. Similarly, poor attitude towards phone use while driving and bad practice of phone use while driving were associated with significantly elevated odds of self-reported crash outcomes. The conclusion calls for a need for greater awareness and intervention aimed at improving knowledge, influencing attitude, and changing the practices around mobile phone use among Nigerian drivers.

It adopted ROPMIS model and Weighted Mean Rank, Gap Model and spearman rank correlation to assess the customers’ satisfaction and port services quality. The result showed a significant relationship between customers’ satisfaction and port services quality. The study recommends that government should prioritize the construction of access roads in and out of the port and port management should focus on the most and least impacting port services to improve on service delivery quality to ensure increased customers’ satisfaction
Excitation Energy Transfer and Trapping in Higher Plant Photosystem II Complexes with Different Antenna Sizes Excitation energy transfer and trapping in higher plant Photosystem II complexes with different antenna sizes

We performed picosecond fluorescence measurements on well-defined Photosystem II (PSII) supercomplexes from Arabidopsis with largely varying antenna sizes. The average excited-state lifetime ranged from 109 ps for PSII core to 158 ps for the largest C2S2M2 complex in 0.01% a-DM. Excitation energy transfer and trapping were investigated by coarsegrained modeling of the fluorescence kinetics. The results reveal a large drop in free energy upon charge separation (>700 cm ) and a slow relaxation of the radical pair to an irreversible state (~150 ps). Somewhat unexpectedly, we had to reduce the energy-transfer and charge-separation rates in complexes with decreasing size to obtain optimal fits. This strongly suggests that the antenna system is important for plant PSII integrity and functionality, which is supported by biochemical results. Furthermore, weused the coarse-grainedmodel to investigate several aspects of PSII functioning. Theexcitation trapping time appears to be independent of the presence/absence of most of the individual contacts between light-harvesting complexes in PSII supercomplexes, demonstrating the robustness of the light-harvesting process. We conclude that the efficiency of the nonphotochemical quenching process is hardly dependent on the exact location of a quencher within the supercomplexes.
Trust in Electronic Markets, A Review and Synthesis of Theories

Electronic markets have grown substantially, and they are considered as a significant form of retail. Despite this growth, the lack of physical transactions between different parties as well as concerns about the privacy of users and the security of transactions has led to a decline in users’ trust in these platforms. This deficiency has motivated many researchers to study the concept of trust in the e-commerce environment. In this paper, we have created a comprehensive and up-to-date framework that synthesises the findings of the previous studies. To achieve this aim, we use a systematic literature review method. We searched 17 top-ranked information systems journals and conferences and reviewed the resultant pool of 127 papers. Beyond investigating the antecedents and consequences of trust in e-commerce, we reviewed the theoretical basis used in the literature. The study concludes with implications of the literature for practice and a critical agenda for future research.
Outcomes of Surgical and Transcatheter Closure of Congenital Coronary Artery Fistulas: Results from a National Audit Database

Congenital coronary arterial venous fistulae are very rare anomalies. We analyzed data from a national procedure database and identified 79 (0.09%) catheter and surgical closures of coronary fistulae out of total of 88061 procedures performed over a 12 year period. Thirty four patients (43%) underwent surgical closure while 45 (57%) patients had catheter closure. Sixty six patients (83.5%) had complete follow-up. There were no early deaths, and mortality at 10 years was 4.8%. Freedom from fistula reintervention was 91.2% for the trans catheter group vs . 100% in the surgical group (p=0.11). We found no differences in outcomes between patients with isolated fistulas and those associated with other congenital defects. Surgical or catheter treatment of coronary fistulae is attainable with no early mortality and good medium term outcomes. However, reintervention rates appear to be higher in trans catheter patients.
Onset of Electron Captures and Shallow Heating in Magnetars

The loss of magnetic pressure accompanying the decay of the magnetic field in a magnetar may trigger exothermic electron captures by nuclei in the shallow layers of the stellar crust. Very accurate analytical formulas are obtained for the threshold density and pressure, as well as for the maximum amount of heat that can be possibly released, taking into account the Landau–Rabi quantization of electron motion. These formulas are valid for arbitrary magnetic field strengths, from the weakly quantizing regime to the most extreme situation in which electrons are all confined to the lowest level. Numerical results are also presented based on experimental nuclear data supplemented with predictions from the Brussels-Montreal model HFB-24. This same nuclear model has been already employed to calculate the equation of state in all regions of magnetars.
Evaluating the Effect of Redundant Resources on Corporate Entrepreneurial Performance

Redundant resources are indispensable resources in corporate entrepreneurship. Nowadays, establishing how to evaluate the impact of redundant resources on corporate entrepreneurial performance has become a critical issue considered by managers. However, few studies have addressed this issue. Based on the perspective of resource bricolage and corporate resource interaction, this work constructs a theoretical model to analyze the influence of redundant resources on corporate entrepreneurial performance. Data were collected in Chinese enterprises. A structural equation modeling (SEM) technique was used. We obtained four valuable conclusions. First, redundant resources have a significant positive effect on corporate entrepreneurial performance. Second, redundant resources exert a significant positive influence on resource bricolage. Third, resource bricolage has a significant positive influence on corporate entrepreneurial performance. Fourth, resource bricolage plays a partial mediation effect between redundant resources and corporate entrepreneurial performance. The insights can provide theoretical and practical guidance for enterprises that intend to use redundant resources to carry out entrepreneurial activities.
Measuring Tourism Destination Brand Equity by Using Associative Networks

A holistic approach to measuring tourism destination brand equity is proposed by using associative networks analysis, to overcome the shortage in the other traditional methods. three Egyptian destinations’ brand equity is tested through data collected by the brand concept map technique. The findings showed a significant relationship between the tourism destination brand equity and two characteristics of brand associations (strength and uniqueness) and a nonsignificant relationship with the third characteristic (favorability). Moreover, the findings indicated a significant relationship between the Central characteristics (degree centrality, betweenness centrality, and closeness centrality) of brand associations and the tourism destination brand equity. Furthermore, managerial Implications for strategic brand development and management are deduced.
Conformational Structure, Infrared Spectra and Light-Induced Transformations of Thymol Isolated in Noble Gas Cryomatrices

The conformational space of the natural product thymol (2-isopropyl-5-methylphenol) was investigated using quantum chemical calculations at the B3LYP and MP2 levels, which revealed the existence of four types of conformers differing in the orientation of the isopropyl and hydroxyl groups. Thymol monomers were isolated in noble gas (Ar and Xe) matrices (at 15 K) and characterized by IR spectroscopy. With the support of B3LYP harmonic vibrational calculations, the two most stable trans-OH-conformers, differing in the isopropyl orientation, were identified in the cryomatrices. The two less stable cis-OH conformers were not detected as they shall undergo fast tunneling to the most stable ones. Annealing experiments in a Xe matrix up to 75 K did not lead to any conversion between the two isolated conformers, which is in accordance with the significative energy barrier computed for rotamerization of the bulky isopropyl group (~24 kJ mol−1). Vibrational excitation promoted by broadband or by narrowband irradiation, at the 2ν(OH) frequencies of the isolated conformers, did not lead to any conversion either, which was interpreted in terms of a more efficient energy transfer to the hydroxyl rotamerization (associated with a lower energy barrier and a light H-atom) than to the isopropyl rotamerization coordinate. Broadband UV irradiation experiments (λ > 200 nm) led to a prompt transformation of matrix isolated thymol, with spectroscopic evidence suggesting the formation of isomeric alkyl-substituted cyclohexadienones, Dewar isomers and open-chain conjugated ketenes. The photochemical mechanism interpretation concords with that reported for analogous phenol derivatives.
How do algae oils change the omega-3 polyunsaturated fatty acids market?

The health benefits of a diet rich in omega-3 long chain polyunsaturated fatty acids (n-3 LC-PUFA) no longer need to be proven. However, while health authorities attempt to increase the consumption of the n-3 LC-PUFAs eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), data from the latest intake surveys demonstrate that EPA and DHA consumption is still too low. A push towards greater sustainability, and a rise in vegetarianism are pushing manufacturers to move from traditional fish oils towards alternative sources. Microalgae oils provide a source of n-3 LC-PUFA with a lower environmental impact and are produced using processes that limit damage to the oils. This review aims to report on oleaginous microalgae strains available for n-3 LC-PUFA production, the processes used for their growth and the extraction and refining processes for their oils. It also addresses the challenges inherent in these products and their fabrication, and some of the novel characteristics of microalgal oils, including their very high n-3 LC-PUFA content and the chemical structure of their triglycerides, that lead to exciting opportunities in their use as functional food ingredients.
Epidemiology of Pediatric Gymnastics Injuries Reported in US Emergency Departments: Sex- and Age-Based Injury Patterns

Background: Despite increasing participation rates in youth gymnastics, the majority of epidemiologic literature focuses on older elite athletes or stratifies athletes by level of competition. Hypothesis: The authors hypothesized that sex- and age-based patterns in youth gymnastics–related injuries exist, which are otherwise overlooked in an unstratified population. Study Design: Descriptive epidemiology study. Methods: Publicly available injury data from the National Electronic Injury Surveillance System were collected on pediatric gymnastics injuries presenting to emergency departments in the United States. Participation data from the National Sporting Goods Association were used to calculate national injury incidence rates in 7- to 11-year-olds (childhood) and 12- to 17-year-olds (adolescence) from January 1, 2012, to December 31, 2018. Z tests were conducted for the comparison of injury rates between girls and boys within each age group and for overall injury rate across age groups. Results: Girls participated in gymnastics at a frequency 6.5 times that of boys in childhood and 13.5 times that of boys in adolescence. An estimated 72,542 youth gymnastics–related injuries were reported in US emergency departments each year. A large proportion (61.3%) occurred in childhood, with female predominance in both age groups. Overall, there was no difference in weighted annual injury rate (injuries per 100,000 athlete-days per year) by age group (6.9 [childhood] vs 8.8 [adolescence]; P = .19) or sex (7.4 [girls] vs 8.1 [boys]; P = .65). In adolescence, boys were more likely than girls to experience injury (16.47 vs 8.2; P = .003). Wrist and lower arm fractures were more common in childhood than adolescence (1.07 vs 0.43; P = .002) and specifically in girls (childhood vs adolescence, 1.06 vs 0.37; P = .001). Ankle injuries and concussions were more common in adolescence vs childhood (P = .01 and .0002). Conclusion: Upper extremity injuries predominated among childhood gymnasts, particularly girls. In adolescence, girls and boys experienced increases in concussions and foot and ankle injuries. Although representing a lower overall number of training gymnasts as compared with girls, adolescent boys experience a higher rate of injuries overall.
Nanocomposites Based on Antiferroelectric Liquid Crystal (S)-MHPOBC Doping with Au Nanoparticles

Modification of the physical properties of the (S)-MHPOBC antiferroelectric liquid crystal (AFLC) by doping with low concentrations of gold nanoparticles is presented for the first time. We used several complementary experimental methods to determine the effect of Au nanoparticles on AFLC in the metal–organic composites. It was found that the dopant inhibits the matrix crystallization process and modifies the phase transitions temperatures and switching time, as well as increases the helical pitch and spontaneous polarization, while the tilt angle slightly changes. We also showed that both the LC matrix and Au nanoparticles show strong fluorescence in the green light range, and the contact angle depends on the temperature and dopant concentration.
A Spatial Spectrum Estimation Method for Optimization and Improvement of Resource Allocation and Management of Public Sport and Health Facilities

With the improvement of people's health awareness, the state increases the construction of public sport facilities, which complicates the allocation and management of resources. The existing spatial spectrum estimation method cannot eliminate the relevant interference data, resulting in duplicate data in the results of resource allocation and management, reducing the accuracy of resource allocation and management. In order to optimize the allocation and management of public sport facilities resources, this study proposes a spatial spectrum estimation method, which is used to deeply tap the potential information in public sport facilities resources and optimize the allocation and management. First, analyze the resources of public sport facilities and put forward the feature vector of allocation and management optimization. Then, use the spatial spectrum estimation method to learn the test samples, get the optimal threshold and weight, and build the resource allocation and management model of public sport facilities. Finally, the accuracy of spatial spectrum estimation method is 98% and the variation range is (0, 10), which is better than the accuracy of the original algorithm is 80% and the variation range is (0, 20). Moreover, change of the spatial spectrum estimation method is smoother, and the correlation between various analyses is better. In unit time, the amount of configuration and management data of spatial spectrum estimation method is higher than that of existing algorithms, which indirectly indicate that the configuration and management time of the spatial spectrum estimation method is short. At the same time, unstructured data account for a large proportion of the data tested this time. Therefore, the accuracy and variation range of the spatial spectrum estimation method is good, which is suitable for the construction of public sport facilities and realizes the optimization of resource allocation and management.
Interaction of impact parameters for simulated falls in sport using three different sized Hybrid III headforms

ABSTRACT This study describes the interaction of impact parameters on peak head acceleration and strain variables for test conditions represented in sport. The Hybrid III 6-year-old child, 5th percentile female, and 50th percentile adult male headforms were subject to parametric tests using a monorail drop tower at four impact velocities (1.5, 3.0, 4.5, and 6.0 m/s), three surfaces (unprotected, protected/helmeted, and well-padded/mat), and four impact locations (frontal, sagittal, combined-plane motions, and a rotationally dominant motion). Scaled finite-element models of the brain were used to obtain peak strains. Regression analyses revealed that compliance produced the greatest increases in head acceleration, while impact velocity was for strain. Smaller headforms were associated with higher responses. Non-uniform trends for impact location were noted and are likely a result of localised headform properties interacting with velocity and compliance. These findings support the need for size-appropriate parameters in the design and development of head protection.
Cenospheres-Reinforced PA-12 Composite: Preparation, Physicochemical Properties, and Soaking Tests

The main aim of this research was the preparation of a polymer–ceramic composite with PA-12 as the polymer matrix and modified aluminosilicate cenospheres (CSs) as the ceramic filler. The CSs were subjected to an early purification and cleaning process, which was also taken as a second objective. The CSs were surface modified by a two-step process: (1) etching in Piranha solution and (2) silanization in 3-aminopropyltriethoxysilane. The composite was made for 3D printing by FDM. Raw and modified CSs and a composite with PA-12 were subjected to the following tests: surface development including pores (BET), real density (HP), chemical composition and morphology (SEM/EDS, FTIR), grain analysis (PSD), phase composition (XRD), hardness (HV), and static tensile tests. The composites were subjected to soaking under simulated body fluid (SBF) conditions in artificial saliva for 14, 21, and 29 days. Compared to pure PA-12, PA-12_CS had generally better mechanical properties and was more resistant to SBF at elevated temperatures and soaking times. These results showed this material has potential for use in biomedical applications. These results also showed the necessity of developing a kinetic aging model for aging in different liquids to verify the true value of this material.
