Optimization algorithms based on convex separable approximations for optimal structural design often use reciprocal-like approximations in a dual setting; CONLIN and the method of moving asymptotes (MMA) are well-known examples of such sequential convex programming (SCP) algorithms. We have previously demonstrated that replacement of these nonlinear (reciprocal) approximations by their own second order Taylor series expansion provides a powerful new algorithmic option within the SCP class of algorithms. This note shows that the quadratic treatment of the original nonlinear approximations also enables the restatement of the SCP as a series of Lagrange-Newton QP subproblems. This results in a diagonal trust-region SQP type of algorithm, in which the second order diagonal terms are estimated from the nonlinear (reciprocal) intervening variables, rather than from historic information using an exact or a quasi-Newton Hessian approach. The QP formulation seems particularly attractive for problems with far more constraints than variables (when pure dual methods are at a disadvantage), or when both the number of design variables and the number of (active) constraints is very large.

Herein, we contextualize, problematize, and offer some insights for moving beyond the problem of monolingual comparative normativity in (psycho) linguistic research on bilingualism. We argue that, in the vast majority of cases, juxtaposing (functional) monolinguals to bilinguals fails to offer what the comparison is supposedly intended to do: meet the standards of empirical control in line with the scientific method. Instead, the default nature of monolingual comparative normativity has historically contributed to inequalities in many facets of bilingualism research and continues to impede progress on multiple levels. Beyond framing our views on the matter, we offer some epistemological considerations and methodological alternatives to this standard practice that improve empirical rigor while fostering increased diversity, inclusivity, and equity in our field.

PurposeThe purpose of this study is to assess if the mediating effect of green innovation capability (GIC) in the relationship between green market orientation (GMO) and new product success (NPS) was conditional on the moderating effects of green knowledge acquisition (GKA) and green brand positioning (GBP).Design/methodology/approachThe analysis was based on primary data gathered using a structured questionnaire, which was developed on a five-point Likert scale of 1-Strongly disagree to 5-Strongly agree. There were 259 manufacturing firms engaged in the study, with data analyzed using PROCESS macro (v.3.4) for SPSS (v.23).FindingsThe research revealed that GMO had no direct effect on NPS among manufacturing firms, the relationship was rather mediated by GIC of the firms. The effect of GMO on GIC was moderated by GKA, whereas the effect of GIC on NPS was moderated by GBP. Overall, the mediating effect of GIC in the relationship between GMO and NPS was conditional on the moderating effects of GKA and GBP.Research limitations/implicationsThe study focused on only knowledge acquisition (green), without recourse to assimilation, transformation and exploitation. These may, however, be very important in explaining the role of knowledge in green innovation.Practical implicationsGreen market-oriented manufacturing firms must seek to also make investments in GIC to transform those concepts into successful innovative products.Originality/valueDespite the increasing number of studies on GMO, very limited concentration has been paid to how firms could leverage on the potentials of GMO to enhance the success of new products introduced into the market. This study did not just establish the effect of GMO on the success of new products but also identified some intervening variables in this relationship.

Purpose This paper aims to determine one explanation for how the self-brand connection is associated with brand loyalty through the brand experience. Brand experience should verify the self-brand connection by acting as a mechanism through which a self-brand connection is associated with brand loyalty. Design/methodology/approach Data were obtained from 317 adults through paid Facebook Boosting of an online survey and analyzed using structural equation modeling. Findings Analyses confirm that brand experience fully mediates the association between self-brand connection and brand loyalty. Research limitations/implications Ensuring a positive brand experience is critical for brand managers opting to maintain consumers’ self-brand connections and brand loyalty. Causality suffered owing to the cross-sectional design of the study. Practical implications Self-brand connection is viewed as consumer-driven. However, by identifying the brand experience to verify the self-brand connection and as a factor that mediates the self-brand connection–loyalty relationship of consumers, brand experience is recognized as a new factor which brand managers can control to manage self-brand connections and brand loyalty. Originality/value This paper is the first to apply the self-verification theory to the self-brand connection–loyalty relationship by explicating brand experience as a mediator of this relationship. This paper argues self-verification is not context-specific and lived experiences with the brand, irrespective of context, establish consumer–brand relationships. This paper confirms the second-order factor structure of the brand experience scale (Brakus et al., 2009) as a mediator in this self-brand connection–loyalty model.

Work fatigue is one of the commonest issue in today's modern industrial world. It has various risk factors ranging from individual factors up until work environment. Not to mention technology developments which surely would affect the conditions of workers. Apron section, in an airport is one of the busiest place where many workers and many activities conducted simultaneously. This requires the workers stay healthy and fit. Fatigue will reduce the level of awareness and performance. Therefore it is substantial to conduct more research related to the risk factors of fatigue and their impact upon apron workers’ performance specifically at Makassar Airport. This study used a cross-sectional design and was conducted in November 2022 with samples of 122 apron workers. The data were analyzed using Path Analysis. This was to see direct and indirect effects through intervening variable (fatigue). The analysis results showed that age (p=0.034), nutritional status (p=0.029), working period (p=0.035), workload (p=0.040), noise (p=0.034) and hot working climate (p=0.040) had correlation or indirect effect on performance through fatigue the intervening variable (p <0.05). It was conclusive that nutritional status, workload, noise and hot working climate had a direct and indirect effect on performance through fatigue as the intervening variable.

The developments of information technology and the advent of new normal in Indonesia had transformed how transaction was conducted, increasing the importance of e-wallet. This study aimed to analyze the effect of perceived ease of use, perceived usefulness, and customer satisfaction on e-wallet continuance intention. This study focused on customers of e-wallets in Indonesia. This research was quantitative research with data collection used the purposive sampling technique. This sampling was conducted by distributing questionnaires to 97 e-wallet customers in Indonesia, with eight questionnaires being rejected due to unmet criteria. Partial Least Square Path Modeling (PLSPM) was used to test the hypotheses. The study found that perceived ease of use had a direct positive influence on continuance intention as well as an indirect positive influence on it through customer satisfaction as an intervening variable, perceived enjoyment did not directly influence continuance intention but had indirect positive influence on it through customer satisfaction as an intervening variable, and customer satisfaction positively influenced continuan­ce intention

PurposeThe purpose of this study is to investigate the impact of Inclusive Leadership (IL) and Organizational Justice (OJ) on employees’ Happiness at Work (HAW). Utilizing a mediation mechanism, the study additionally uncovers the mediating impact of Workplace Inclusion (WI).Design/methodology/approachThe research involved a cross-sectional study with a quantitative methodology, collecting data from 311 employees working in IT sector firms in India by administering standardized questionnaires. Statistical analyses, including Partial Least Square Structural Equation Modelling using SmartPLS4.0, were conducted to examine the relationship between constructs.FindingsThe hypothesized mediation model was supported. WI mediated the relationship partially between OJ and HAW, whereas there is a full mediating effect of WI on the IL–HAW relationship. Overall, the study shows that by providing fair treatment, inclusive leaders promote inclusivity among employees, further enhancing HAW.Research limitations/implicationsThe study’s implications suggest that leaders, with their inclusive behaviour and fair practices, can have a significant positive impact on employees’ workplace happiness when accompanied by a sense of inclusivity among employees.Practical implicationsOrganizations and leaders can utilize this study’s findings to promote inclusiveness and HAW, which can be a key to organizational growth and development in a post-pandemic era.Originality/valueThis study contributes to the research literature by addressing the unexplored relationship between IL, OJ and HAW. The exclusive as well as inclusive focus on the mediating role of WI adds new insights and enriches the understanding of the intricate conceptualization of the variables under study.

IntroductionFew is known regarding the intervening variables between pathological narcissism and sadism personality. Specifically, envy is a psychoanalytical construct that appears especially promising in illuminating such relationships.ObjectivesTo extend the knowledge regarding the nomological network of pathological narcissism.MethodsWe administered to a sample of Italian adults a battery of self-report questionnaires including the Italian version of the Benign and Malicious Envy Scale, the Assessment of Narcissistic Personality, The Narcissistic Admiration and Rivalry Questionnaire and the Pathological Narcissism Inventory.ResultsFirst, the Italian version of the Benign and Malicious Envy Scale showed good fit indexes confirming the original factorial structure as well as configural invariance. We found that only the grandiosity facet of the Pathological Narcissism Inventory, the Rivalry subscale of the Narcissistic Admiration and Rivalry Questionnaire and the Malicious subscale of the Benign and Malicious Envy Scale positively and significantly predicted Assessment of Narcissistic Personality scores. Moreover, throughout a structural equation modeling approach, the hypothesis that rivalry and malicious envy both mediate the relationship between grandiosity and sadism was empirically supported.ConclusionsThe use of the Benign and Malicious Envy Scale resulted to be promising in the investigation of the nomological network of pathological narcissism. Limitations and future directions are discussed.DisclosureNo significant relationships.

The purpose of this study aims (1) Investigate the role of the item constructs access to information, labelling and peer pressure, sense of retribution, and circular economy perception on green individuals feelings; (2) Evaluate the role of green business orientation and product quality on perceived of green marketing strategic orientation through the second-order analysis test. As a design methodology we involved 178 respondents at Starbucks outlets in Makassar City, Indonesia, with purposive random sampling. The analysis was conducted through a second-order analysis approach to test the variable constructs and through direct and indirect testing by involving attitude towards green marketing and brand integrity as intervening variables. The result of this study shows all items have a significant role in shaping the perceived of green marketing strategic orientation and green individuals feelings through the second-order analysis approach. Direct test showed a positive and significant effect except in the relationship between perceived of green promotion and innovation and brand integrity. Indirect test shows that the relationship between perceived of green marketing strategic orientation, perceived of green promotion and innovation, and purchase intention with attitude towards green marketing as an intervening variable is not significant. Similarly, the relationship between green individuals feelings, purchase intention, brand integrity, and perceived of green promotion and innovation as intervening variables is also not significant.

PurposeExisting research on knowledge management processes (KMPs) and absorptive capacity (ACAP) is primarily conceptual and descriptive in nature, and empirical research confirming the real impact of KMPs when developing ACAP is lacking. Furthermore, the relationship between ACAP and organizational performance (OP) has not been adequately studied. Hence, the purpose of this paper is to introduce a comprehensive, delineated and integrated conceptual model which encompasses KMPs, ACAP and OP. Then, an empirical investigation is undertaken to test the relationships among the proposed study model variables.Design/methodology/approachIn total, 245 questionnaires were useable. Partial least square 3.3.3 is utilized to examine the validity of the measurement model and test the hypotheses.FindingsThe findings of this study suggest that KMPs influence ACAP and ACAP affects OP. Finally, the results show that KMPs affect OP directly and indirectly through ACAP (mediator).Practical implicationsThe results of this study help managers to ascertain the managerial practices that can be employed as well as determine the level of effort and resources necessary to enhance ACAP. Additionally, managers should shed additional light on the ACAP's positive implications for OP.Originality/valueThis study focuses on the conceptualization of KMP and empirically tests the effect of these individual processes on ACAP and on OP. Finally, the relationship between KMPs and OP, although implied, needs to be addressed empirically in the research literature through utilizing ACAP as mediator between KMPs and OP, this appears to be the first study to try to achieve this main objective.
