Purpose The purpose of this paper is to know whether organizational citizenship behavior mediates the effects of personality, organizational commitment, and job satisfaction. Design/methodology/approach This research was conducted in the city of Makassar with the entire population being lecturer with the status from a permanent lecturer foundation. By using the Slovin formula, a sample of 295 respondents was obtained. Structural equation modeling (SEM) was used as an inferential statistical analysis technique to test the hypothesis of the research. Findings The results of the study found the mediating effect (indirect effect) of variable organizational citizenship behavior was found in between personality, organizational commitment and job satisfaction on performance, which thus indicates that the higher the personality, organizational commitment and job satisfaction the higher the performance, and if mediated, organizational citizenship behavior is also higher. Originality/value Organizational citizenship behavior research has been conducted on student classroom and career success. Additionally, organizational citizenship behavior has been researched for a critical review of the theoretical and empirical literature, which has provided suggestions for future research. Thereby, on paper originality the variables shown to be used are personality, organization commitment, job satisfaction, organizational citizenship behavior, and performance. Furthermore, the method used in this research is the SEM. The investigation was performed at two private colleges in Indonesian Muslim University and Muhammadiyah University Makassar, South Sulawesi, Indonesia, where no studies were conducted on the same topic previously.

Purpose This research aims to examine the moderating effect of strategic orientation on the effect of environmental uncertainties on business performance and the moderating effect of innovations on the effect of environmental uncertainties on performance of the business in the aviation industry in Indonesia. Design/methodology/approach Research data were collected in stages by means of interviews with corporate leaders of Indonesian airlines and branch managers of several airports, as well as with the Directorate of Civil Aviation as the regulator. A pre-test and focus group discussion (FGD) were conducted to directly determine the questionnaire aspects of the research object, following which an immediate revision was made to the questionnaire. The data from the survey used in each variable were obtained from the mail questionnaire survey. The data collected using the survey are the main data used in the present study. Findings The model of environment–strategy–performance (ESP) can work well in improving performance if supported by innovations. These findings deepen the ESP paradigm in the aviation industry (Miles and Snow, 1978; Segev 1987; Covin and Slevin, 1989; Miller and Shamsie, 1996) that during conditions of high environmental uncertainties, strategic orientation, rather than a single response, will be effective if supported by innovations that provide the strategy with flexibility. The initial implications of these modeling results generate the findings that the effect of environmental uncertainties in the aviation industry (classified as strictly regulated) on performance of a company is largely determined by the direction of the strategic orientation and the innovation level. Research limitations/implications Interactions between innovations and environmental uncertainties have a significant negative effect on the achievement of business performance of the branches with a coefficient of 0.02 and a t-value of 2.00, meaning that the innovation level of a branch has an increasingly stronger influence on the business performance of the branch in the uncertain environment with limitations or underestimated by the branch manager or the innovation level of the branch is not supported with airport facilities and services, which means that the provision of airport facilities and services is inversely proportional to the needs of the airline branches. In other words, the variable “innovations” is a moderating variable for the effect of environmental uncertainties on business performance. Practical implications The results of the modeling performed in this research also show that innovations play a major role in the implementation of the ESP model (Blumentritt and Danis, 2006). The empirical phenomena and descriptive analysis results suggest that the Indonesian airlines which have been quite successful and have demonstrated an above-average performance possess higher levels of innovations. This finding corroborates that of previous studies that environmental uncertainties and direction of strategic orientation will determine the ability of a company to overcome the barriers to innovations, by maximizing innovative resources in achieving the target of innovations (Manu, 1992; O’Regan and Ghobadian, 2005; Hult et al., 2003), and more specifically, it indicates that strategic orientation that is prospective in nature leads to a high level of innovations (Salavou et al., 2004). Social implications The research findings indicate that innovations have a central role in the ESP models and are able to offer a new concept as a modification of the ESP model which in the study is called ESIP. The role of innovations in the ESIP model puts innovations as a variable moderating the effect of environmental uncertainties on performance and the effect of strategic orientation on performance. Moreover, based on the summary of the results for the analysis of the ESIP model, the following can be explained: first, environmental uncertainties have a significant and positive effect on the innovation level or the higher the level of environmental uncertainties, the more is the number of the innovations that an Indonesian airline branch creates. External environmental conditions that are likely to be complex and dynamic found in the area of operations make the branch management more able to identify barriers to innovations and manage resources to be more creative and productive for the attainment of the targets of innovations. Originality/value Innovations in business models as a new effort in improvisation specific to the business stage of the basic model (not very valuable) become more advanced business processes to produce products that are more valuable for consumers, at a more efficient cost with better profitability (Chesbrough, 2007b). So far, research on the role of innovations in response to environmental uncertainties and implementation of strategies to improve the performance of the ESP model is still done partially, so that there is no comprehensive model to describe the role of innovations in this ESP model, or let us say that a gap exists between theories and opportunities to conduct further research on the role of innovations in the ESP model.

Purpose This study aims to more deeply examine the various types of testing mediations and use the comparison test by using test-based mediation Sobel models and Bayesian approach. The purpose of this study are to apply the traditional (using indirect effect) and Sobel test, extend Yuan and MacKinnon (2009) work on Bayesian mediation analysis. Both analysis methods of mediation (Traditional, Sobel Test and Bayesian estimation) should apply in the research of management, by using structural equation modeling (SEM) in a structural model, with one mediation, one exogenous (independent) and one endogenous variable. The meta-analysis approximation has been used to investigate the job satisfaction as a mediation in the relationship between employee competence and performance (endogenous). Design/methodology/approach Data were collected from ten dissertations of students of the Management Doctoral Program at the Brawijaya University from 2009 until 2013; data were analyzed for the mediation variable of job satisfaction (M) in the relationship between employee competence (X) and employee performance (Y) (Muindi and Obonyo, 2015; Olcer, 2015; Sattar et al., 2015; Khan and Ahmed, 2015). A researcher can determine the mediating variable and whether it is complete or partial or if mediation exists in several ways. Findings The results of the above findings using meta-analysis showed that 60% of previous research states that job satisfaction is a partial mediation on relationship competence of the performance, 10% of previous research states that job satisfaction is a full mediation on relationship competence of the performance and 30% stated that job satisfaction is not pemediasi (pemediasi means Mediation variable) on the relationship between competence and performance. This research found that all three approaches provide similar conclusions for ten previous research. Research limitations/implications The findings showed that the Sobel approach and the Bayesian approach provide results that are more sensitive than the traditional approach. Practical implications In my opinion, the rule to investigate the mediation variable should be completed with the conditions (1) q (theta) is not statistically significant, (2) α (alpha) and β (beta) are significant, and (3) q’ (theta) is significant, and increase when M is include as an additional predictor. This condition called partial mediation. Social implications The traditional method is simpler and easy. The method is less sensitive and is not sufficient for investigating the mediating variables. In general, the method results in a mediation variable, but it cannot be used to determine either partial or complete mediation variables. So, investigation by Baron and Kenny Methods (in Hair et al., 2010), the rule or testing called Sobel Test and another approach such as Bayesian to determine the mediation variable is necessary. Originality/value Various methods for detecting mediating/intervening have been widely used in previous research as a method of measurement using indirect effect (Hair et al., 2010), and calculations have been performed using Sobel test (Baron and Kenny, 1986) and Bayesian approach (Enders, 2013). In this study, I wanted to more deeply examine the various types of testing mediations, and use the comparison test by using the test-based mediation Sobel models and Bayesian approach (Baron and Kenny, 1986; Enders, 2013). The statistical application should not be complicated and difficult, it but must rather be simple and easy, so that it is user-friendly. The traditional method is simpler and easier than the other methods, but how sensitive is it? This research is conducted to investigate this problem. The evaluation of mediating mechanisms has become a critical element of behavioral science research (Enders, 2013), especially in the field of management, not only to assess whether (and how) interventions achieve their effects but also, more, broadly, to understand the cause of behavioral change. Methodologists have developed mediation analysis techniques for a broad range of substantive applications. However, methods for estimating mediation mechanisms with various methods have been understudied. The purpose of this study is to apply the traditional (using indirect effect) and Sobel tests and extend Yuan and MacKinnon’s (2009) work on the Bayesian mediation analysis. Both analyses methods of mediation (traditional and Sobel test and Bayesian estimation) should apply in the research of management, by using structural equation modeling (SEM) in a structural model, with one mediation, one exogenous (independent) and one endogenous variable. The meta-analysis approximation has been used to investigate job satisfaction as the mediation in the relationship between employee competence and performance (endogenous). This study uses software R to complete the mediating effect (Enders, 2013). R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers et al. R provides a wide variety of statistical analyses such as SEM and Mediation test. R provides an open source route for participation in that activity. The Bayesian estimation approach provides an R function and a macro that applies the method of mediation analysis.

Purpose This study aims to (1) examine the mediating effect of strategic orientation on the effect of environmental uncertainties on business performance, and (2) examine the mediating effect of innovations on the effect of environmental uncertainties on performance of the business in the aviation industry in Indonesia. Design/methodology/approach The research design was conducted through a survey, and the testing form was carried out using “Relationship Causal Studies” or a study to analyze the causality among environmental uncertainties, strategic orientation, innovations and performance of branches/stations of airlines in the Indonesian aviation industry. The sample was selected by determining the number of branches/stations of the Indonesian airlines to be selected into the sample, then more than one unit managers were selected as respondents representing their respective branches/stations. The number of the target sample in this study was 250 branches. Techniques used to address the hypotheses of the present study were Descriptive Analysis and Structural Model Analysis. The inferential statistical analysis focuses on the subject of the analysis and data interpretation to draw conclusions. Findings These research findings provide a contextual overview of the aviation industry in Indonesia that activities to make innovations in airline branches play a vital role in encouraging business performance. Moreover, the analysis shows that the more innovative a branch the better its business performance. This corroborates the finding (Spacapan and Bastic, 2007; Talke, 2007) that being highly innovative can ensure sustainable and long-term business performance. Research limitations/implications The findings of this research suggest that innovations mediate the effect of environmental uncertainties on business performance. These findings corroborate the results of previous studies that suitability between strategic orientation and innovations of a company in response to environmental uncertainties will affect performance of the company (Li and Gima, 2001; Manu, 1992). These findings also strengthen the view that companies with a higher level of innovations (innovative) have better business performance and competitive advantages (Kessler and Chakrabarty, 1996; Salavou et al., 2004; Spacapan and Bastic, 2007). Furthermore, based on findings, it can be interpreted that management that is able to overcome barriers to innovations, maximize innovation resources and achieve the target of innovations in the form of creation of better products/services will have better performance. The ability of the management to identify and overcome barriers to innovations and maximize the sources of innovation will generate products or services that can be accepted by the customers and eventually these products and services will be able to compete with better business performance (Blumentritt and Danis, 2006). Practical implications Findings of this research indicate the positive and significant mediating effect between environmental uncertainties on business performance, through the mediation of innovations, competitive conditions of the industrial environment which can encourage organizations to evolutionarily be more innovative in managing business to compete in the long term (Franke, 2007). This is also consistent with the theory of evolutionary economics (Nelson and Winter, 2000) that the old strategy may not suit the changes in the environment, and therefore companies should continue to seek new breakthroughs with persistent improvement and innovations. Social implications Dynamic and competitive conditions of the industrial environment require organizations to more intensively explore sources (capabilities) of innovations and accelerate generation of the innovations (Franke, 2007; Berry et al., 2006; Dobni, 2006; Davila et al., 2006; Spacapan and Bastic, 2007). Contextually, it appears that the competitive conditions of the aviation industry in either the short term or in the long term require business actors to be more innovative and to survive (Franke, 2007). Originality/value Innovations in business models as a new effort in improvisation specific to the business stage of the basic model (not very valuable) become more advanced business processes to produce products that are more valuable for consumers, at a more efficient cost with better profitability (Chesbrough, 2007b). So far, research on the role of innovations in response to environmental uncertainties and implementation of strategies to improve the performance of the environment-strategy-performance (ESP) model is still done partially so that there is no comprehensive model to describe the role of innovations in this ESP model, or let us say that a gap between theories and opportunities to do further research on the role of innovations in the ESP model exists.

Purpose The aim of this research is to investigate the consistency between the criterion validity and the unidimensional validity – case study in management research. Design/methodology/approach The investigation of construct validity and criterion validity by using confirmatory factor analysis is presented in this paper. Data were found from three dissertations of Doctoral Program of Management on Brawijaya University and Airlangga University. It consists of seven variables. The first data consist of three variables, i.e. X1, X2 and Y1; the second data consist of two variables, i.e. X2 and Y1; and the third data consist of two variables, i.e. X3 and Y1. Findings The measurement instrument of latent variables must be valid. There are many methods of construct validity, i.e. unidimensional validity and criterion validity. The criterion validity is less sensitive than unidimensional validity, that is, it is more simple and easy for application. Research limitations/implications The research is limited to only analyzing criterion validity and unidimensional validity. Practical implications The unidimensional validity is more sensitive than criterion validity, that is, it is more complex and difficult for application. But if structural equation modeling (SEM) is used to analyze data, the unidimensional validity test must be used; this causes SEM to have constraint, i.e. factor indeterminacy. Social implications Majority in Dissertation of Doctoral Program (Brawijaya University and Airlangga University) using criterion validity to investigate the instrument validity, without investigating the unidimensional validity, is included in this paper. Originality/value To investigate the instrument validity, no studies have focused on the selection of instrument validity, particularly in the field of management.
