The proposed Sliding Mode Control-Global Regressive Neural Network (SMC-GRNN) algorithm is an integration of Global Regressive Neural Network (GRNN) and Sliding Mode Control (SMC). Through this integration, a novel structure of GRNN is designed to enable online and. This structure is then combined with SMC to develop a stable adaptive controller for a class of nonlinear multivariable uncertain dynamic systems.

In this study, a new hybrid (SMC-GRNN) control method is innovatively developed.

A novel structure of GRNN is designed that can be learned online and then be integrated with the SMC to develop a stable adaptive controller for a class of nonlinear uncertain systems. Furthermore, Lyapunov stability theory is utilized to ensure the hidden-output weighting values of SMC-GRNN adaptively updated in order to guarantee the stability of the closed-loop dynamic system. Eventually, two different numerical benchmark tests are employed to demonstrate the performance of the proposed controller.

This article proposes a chattering‐free sliding mode control scheme with unidirectional auxiliary surfaces (UAS‐SMC) for small miniature autonomous helicopters (Trex 250).

The proposed UAS‐SMC scheme consists of a nested sequence of rotor dynamics, angular rate, Euler angle, velocity and position loops.

It is demonstrated that the UAS‐SMC strategy can eliminate the chattering phenomenon exhibiting in the convenient SMC method and achieve a better approaching speed.

The proposed control strategy is implemented on the helicopter and flight tests clearly demonstrate that a much better performance could be achieved, compared with convenient SMC schemes.

Sexual violence prevention programs on college campuses have proliferated in recent years. While research has also increased, a number of questions remain unanswered that could assist campus administrators in making evidence-based decisions about implementation of prevention efforts. To that end, the field of prevention science has highlighted the need to examine the utility of booster sessions for enhancing prevention education. The purpose of this paper is to examine how two methods of prevention delivery – small group educational workshops and a community-wide social marketing campaign (SMC) – worked separately and together to promote attitude change related to sexual violence among college students.

The two-part study was conducted at two universities. Participants were from successive cohorts of first year students and randomly assigned to participate in a bystander based in-person sexual violence prevention program or a control group. Participants were later exposed to a bystander based sexual violence prevention SMC either before or after a follow-up survey. Analyses investigated if attitudes varied by exposure group (program only, SMC only, both program and SMC, no prevention exposure).

Results revealed benefits of the SMC as a booster for attitude changes related to being an active bystander to prevent sexual violence. Further, students who first participated in the program showed enhanced attitude effects related to the SMC.

This is the first study to look at the combination of effects of different sexual violence prevention tools on student attitudes. It also showcases a method for how to investigate if prevention tools work separately and together.

The purpose of this paper is to analyze the existing mechanism of school management committees (SMCs) and to propose an improved framework for strengthening its process and outcomes. In 2005, the Education and Literacy department, Government of Sindh decentralizes the administrative and operational authorities to school level in the form of SMCs. These committees have been vested with several roles and responsibilities in accordance with the objective of SMCs set in by government in assistance with different international donor agencies.

The purposively selected respondent that includes 35 stakeholders among which 25 stakeholders has been interviewed individually while other ten has been interviewed in the form of two focused groups consisting of five members each. The findings based on the interviews are analyzed using the thematic analysis. This study analyzes the formation of SMCs, roles and responsibilities of members, Allocation SMC funds and its utilization methods. The study includes the challenges faced by these committees in school administration and operations with their recommendations for overcoming such challenges. Some common challenges include limited financial resources, interference of landlords and potential people of the community, limited administrative authorities and lack of interest of government toward government schools.

The recommendations have been categorized into three broad themes: strengthening of mechanism, strengthening through functions, roles and responsibilities and revising SMC fund allocation and its utilization.

The study proposed an improved framework for strengthening the process and outcomes of SMC.

The increasing use of social media after work hours for work purposes, termed social media connectivity (SMC), is an emerging phenomenon in supply chain management. Although SMC can have debilitating effects on supply chain professionals and their organizations, research on its effects on work-related attitudes, especially turnover intentions, remains largely unexplored. The purpose of this paper is to investigate the influence of SMC on voluntary turnover of supply chain professionals and the resulting implications for them and their organizations.

The study draws from the conservation of resources theory and the concept of information overload to explain how SMC leads to emotional exhaustion and impacts turnover intentions of supply chain professionals, contingent on work–life balance. The model is tested using survey data (n=325) collected at multiple times from a large Chinese pharmaceutical manufacturer and distributor with spatially dispersed workforce and distribution facilities.

The results confirm that emotional exhaustion mediates the association between SMC and turnover intentions and that SMC exacerbates the intentions of supply chain professionals to quit their jobs. However, work–life balance is found to dampen the exhausting effects of SMC on emotional exhaustion thereby reducing its debilitating effects on turnover intentions of supply chain professionals.

The focus on SMC highlights the need for greater understanding of the dark side of social media on supply chain professionals and their organizations and how SMC can be better managed in an age of social media ubiquity.

This paper aims to examine the extent to which social media competence (SMC) determines exporting companies’ actual adoption of social media applications, which eventually might impact these firms’ performance. Quantitative study where data were collected through a web-based survey addressed to Spanish exporters. SEM is employed for testing the hypotheses. SMC has an influence on the firm’s actual use of these social media applications, which in turn has an impact on the firm’s performance. However, the intention to use social media applications mediates the relationship between the firm’s SMC and its social media usage.

This study aims to investigate the impact of the source of the content in social media communication and the content distribution intensity on consumer-based brand equity (CBBE) dimensions and how the study will eventually impact purchase intention.

A total of 521 samples were collected using an online survey questionnaire. The respondents' validity was verified using purposive sampling techniques, and the responses were analysed using SmartPLS 3.0.

The authors outlined the fundamental mechanisms of what makes social media communication effective and discovered that emotional-based brand equity dimensions (brand association and brand loyalty) remained significant in influencing purchase intention. However, attribution-based brand equity dimensions (perceived quality, brand trust and brand awareness) are found to have no impact.

This study decomposed social media communication into three different dimensions, and the authors' result showed that the dimensions do not impact CBBE to the same extent. The authors concluded that some CBBE dimensions, which appear to be a rigour determinant of purchase intention over time, have a feeble effect during the pandemic. The existing relationship between the CBBE dimensions with purchase intention might not hold in the pandemic context. The authors suggested that anxiety or pandemic fear could alter the normal consumer buying process and make some well-established relationships not hold. As research indicates that pandemics are reoccurring events, the authors' study contributes to the global effort to dampen some of the pandemic-related effects on business and marketing.

The purpose of this study was to examine factors influencing user selection of individual works in a collection of digitized sheet music.

Google Analytics page view data were grouped by source (directing link) and correlated with five factors: inclusion in a collaborative indexing project (Sheet Music Consortium); browse list order; cover appearance; inclusion in mini-collections; and presence of links to audio versions.

Four of the five factors examined showed some influence on user selection: Works listed in the Sheet Music Consortium had more views/work than those not listed; Works at the top of the Sheet Music Consortium browse list had more views by Consortium users than those lower down; Works with cover graphics had more views/work than those with covers containing words alone; Works included in mini-collections received more views/work from users with access to those mini-collections; Works with links to audio versions did not have more views/work than works without links.

The most important finding of this study is that the best way to increase the use of individual collection items may be to participate in a large and well-known collaborative index such as the Sheet Music Consortium.

This is the first study using Google Analytics to examine factors influencing user selection of individual digital collection items.

This paper intent to design, develop, and fabricate a robust cascaded controller based on the dual loop concept i.e. Fuzzy Sliding Mode concept in the inner loop and traditional Proportional Integral controller in the outer loop to reduce the unknown dynamics and disturbances that occur in the DC-DC Converter.

The proposed Fuzzy sliding mode approach combines the merits of both SMC and Fuzzy logic control. FSMC approach reduces the chattering phenomena that commonly occurs in the sliding mode control and speed up the response of the controller.

In most of the research work, the inner current loop of cascaded controller was designed by sliding mode control. In this paper FSMC is proposed and its efficacy is confirmed with SMC -PI. In most uncertainties, FSMC-PI produces null maximum peak overshoot and a very less settling time of 0.0005 sec.

The presence of Fuzzy SMC in the inner loop ensure satisfactory response against all uncertainties such as steady state, circuit parameter variations and sudden line and load disturbances.

This study examines a moderated moderation model in which the hardiness of chief marketing officers (CMOs) moderates the relationship between CMOs' future focus and firms' sustainability marketing commitment (SMC), and this moderating effect is moderated by CMOs' proactive personality.

A sample of 298 CMOs of firms in Vietnam was surveyed to collect data. Confirmatory factor analysis was employed to validate the measures of the constructs used in the model and structural equation modeling (SEM) was used to test the model and hypotheses.

The SEM results reveal that CMOs' future focus had a positive relationship with firms' SMC. Furthermore, both CMOs' hardiness and its interaction with CMOs' future focus had positive effects on firms' SMC. Finally, the three-way interaction between CMOs' future focus, hardiness and proactive personality had a positive effect on firms' SMC.

The study findings assist firms in emerging markets in understanding the roles of some key personality-based resources of CMOs in fostering firms' SMC.

This study is among the first to investigate the roles of CMOs' personality-based resources (i.e. future focus, hardiness and proactive personality) in firms' SMC, offering insight into the sustainability marketing literature.
