Black Box ” between Authentic Leadership and Follower Commitment

The aims of present study was to test the theoritical linking model of authentic leadership with personal identification, social identification, trust to leader, and organizational commitment in higher education institution. The quantitative methodology used in this study incorporates cross-sectional survey method. Analysis was conducted on the sample of 150 academic and administrative staff from one of private business school in Yogyakarta special region. The direct effect between variables analyzed using path analysis and mediating mechanism using procedure from Baron and Kenny (1986) and Sobel test. Results reveal positive and significant direct effect of authentic leadership to personal identification, social identification, trust to leader and organizational commitment. Folower’s personal identification mediate the effect of authentic leadership to follower’s trust and commitment. Follower’s trust to leader mediate the relationship between authentic leadership and follower’s commitment. Meanwhile, social identification does not mediate the effect of authentic leadership to follower’s commitment and trust to leader. Implication for management theory and practice are discussed.

INTRODUCTION
Organizations are increasingly concerned about the moral aspects of economic, geo-political and technological developments (Clapp-Smith et al., 2009).Further, manage ment scholars have responded to these calls by pursuing research in authentic leadership.
The concept of authentic leadership was developed on the basis of the attitudes and behaviors of leaders who positively influence their followers and the models that incorporated positive organizational beha vior (Rego et al., 2016).Authentic leadership has been identified as a leadership model that influence the leader who exhibit multiple leadership style, and open up an unexplored area in leadership research (Clapp-Smith et al., 2009).Compare to other leadership style, authentic leaders act to capture positive self-develop ment following the interna lized moral values and thus tend to win strong trust of follo wers (Walumbwa et al., 2008).
Authen tic leadership consist of four dimen sions: 1) Self-awareness, defined as the extent to which leaders are aware of their strength, weakness, and motivation, as well as know very well how employees view their leaders; 2) Balanced proces sing, means asking others (subordinates) opinions to process informa tion and make decisions; 3) Relational trans pa rancy refers to exposing oneself, such as expressing feelings and sharing thought and information; 4) Inter nalized moral perspective, shows that leader's behaviors are guided by moral standard, certain belief and internal values (Avolio et al., 2004;Luthans et al., 2005;Walumbwa et al., 2008).
There is a gap in our knowledge of how leadership makes a difference; that is, we do not know the mechanism involved in influencing the most effective and sustain able outcomes (Wong et al., 2010).One of the main objectives of this study is to extend the development of authen tic leadership theories, especially exploring the process by which authentic leadership can increase positive work behavior.The development of theory through empirical research is still needed to build a strong theoretical model.Moreover, through this hypothesis tes ting, we expec ted to provide support for the justification model that has been built pre viously.
Consis tent with an authentic leader ship mo del developed by Avolio et al. (2004), we involve personal identi fication and social identification as the key mecha nisms.We look for the potential mediating effect from these variables in their roles in connecting authentic leaders and commit ments (Hogg, 2001;Kark et al., 2003;Avolio et al., 2004).Shamir et al. (2000) states that the process of identification both individual and social is part of the self-concept.Furthermore, Individual's high degree of selfconcept will be able to cultivate a moti vational attitude and en courage a person to show positive attitude and behavior for himself and his group.Some studies point out the influence of authentic leadership on organi zational commitment (Walumbwa et al., 2008).Individual's commitment to their organi zation has been considered a critical issue in management studies (Rego et al., 2016).It is well known that organizational commitment becomes an important and vocal variable to support employee perfor mance.
Prior study suggest that leader perceived authentic by subordinates can raise trust (Walumbwa et al., 2011).In its relationship on leader trust, authentic leadership is described as the root component of effective leader ship required to build trust (Avolio et al., 2004).Specifically, this model of leadership focuses on the positive role modeling of honesty, inte grity and high ethical standards to build leader-follower relation ship (Wong et al., 2010).Accor dingly, employees can carry out their duties faithfully through the leader's authentic leadership.This leads to employee's identi fication within the organization based on their trust in leaders, which is ultimately improving job performance (Lee et al., 2016).
Although there has been theoretical support for authentic leadership, so far there has been little empirical research to better understand the mechanism by which authentic leaders exert their influence on work attitudes (Wong et al., 2010), not to mention re search of au thentic leadership in higher education context.In this study, originality and expected contribution lays in several ways.First, this research bridges the gap between authen tic leadership, trust to leader, and organi zational commitment.Through testing the mediating mechanism, this research ex plores the mechanism on how authentic leadership can affect trust and organizational commitment.
Second, this study pro vides some empirical evidence to testify the pre dictive and nomological validity of this construct (Liu et al., 2015).The third con tri bution related to the research context.Literature review by Gardner et al. (2011) shows that the context of authentic leadership research is dominated by Wes tern cultural back grounds with more than 60 percent of research conducted in the United States and surrounding area.The present study provides the first test theoretical linking model in a higher education sample in Indonesia con text.This research will add to our knowledge based on empirical evidence from different cultural contexts, caused by different cultural backgrounds.The people of South East Asia are more paternalistic in nature and require long term, fair, and trusted relationship with their leader and organization.
Finally, this study will provide empirical evidence on the role of follower's identification with their leader and social identification with organization in relation to forming a positive work attitude derived from authentic leadership (Hogg, 2001;Kark et al., 2003;Avolio et al., 2004).

Hypothesis Development Authentic Leadership and Trust
Trust has been widely recognized as vocal variable in leadership study (Dirks & Ferrin, 2002;Stander, 2015).The widely accepted definition of trust is the willin g ness of a person or a particular person to be vulnerable to the other's attitude based on the expectation that the other side is acting with certain actions important to the truster, regardless of the ability to control such other party (Mayer et al., 1995).
Compare to other leadership style, authentic leaders act to capture positive selfdevelop ment following the interna lized moral values and thus tend to win strong trust of follo wers (Walumbwa et al., 2008;Leroy et al., 2015).Prior study suggest that leader perceived authentic by subordinates can raise trust (Walumbwa et al., 2011;Hsieh & Wang, 2015).When authentic leaders take an ethical approach to decision making and engage in balanced processing instead of making snap decision, followers may be more willing to place trust in the leader's future action because they can use past experience to predict future response (Clapp-Smith et al., 2009).Authentic leadership show their member personal consideration and respect, which enhan cing trust (Avolio et al., 2004).
The social exchange theory that has been applied to the study of leader-member exchange can be used as a connecting theory between authentic lea der ship and trust.Employees treated fairly with leader's concern might have more reciprocity (Mayer at al., 2009).The theory of social ex change is trust-based relationships that the people involved in exchange will be mutually beneficial.Furthermore, it is used to confirm the relationship between supe rior's leadership and follower's trust beyond economic and transactional ex change between them (Lee et al., 2016).Leaders with positive psychological capa bilities (i.e.authentic leaders) are trusted by members (Norman et al., 2010), and its a must that as a leader they must shows their consideration, because it is impossible to build trust without it (George & Sims, 2010).We have therefore formulated the following hypothesis: H1: Authentic leadership posi tively affect individual's trust to leader.

Authentic Leadership and Organi zational Commitment
Organizational commitment is an important concept in the organizational behavior (Dhar, 2015).Organizational commit ment is described as a psycho logical state that shows employees' association with the organization and see the implications of employee deci sions to stay or leave the organization (Allen & Meyer, 1990).While Wartini and Harjiyanti (2014) define organizational commitment as the process of employees to identify themselves with the rules, values and objectives of the organization.
Social exchange theory used to explore the relationship between authentic leadership and organizational commitment.The fundamental premise of the theory of social exchange is the sense of duty to reciprocate the favorable attitudes received in the future.This is because authentic leadership is characterized by being trans parent, truthful, walk their talk accordance with their values, and maintain genuine relationship (Gardner et al., 2005;Walumbwa et al., 2008).Both parties, leader and subordinates, will know clearly others come with a high congruence of compatibility between the basis of trust and action.
Over time, subordinates realize that decisions that will or have been made by the leader has been through an open process and the results of the information gathering.When a psycho logical contract is esta blished, a common understanding of the ac tion plan and responsibilities of each party also arises.The conformity of expectations from each side will create a trust foundation that enhances existing relationships and commitment between superiors and leader (Gardner et al., 2005).This means that the higher the level of perceived authenticity, the more commit ted individuals are to achieve goals objectives (Kernis, 2003).We have therefore formulated the following hypothesis: H2: Authentic leadership posi tively affect individual's organiza tional commitment.

Authentic Leadership and Mediating Mechanism Personal Identification and Social Identification as Mediating Variables
The importance of personal and social identification in the leadership process as well as the impact on follower behaviors showed by several prior studies (Kark et al., 2003;Wong et al., 2010).Perceptions of personal identification appear in when subordinates believe their leader to be a self-referential (Pratt, 1998).Moreover, personal identification refers to the process of the emergence of one's beliefs about another (leader) that their leader represents the subordinate's self or reflects themselves (Kark & Shamir, 2013).
The identification of employees with leaders is a relational subordinate relation ship with their superiors, which differs from relational relations to social identity based on group membership and social identifi cation processes (Kark et al., 2003;Wang & Rode, 2010).The identification of employees with their leaders typically portrays the process of personal identifi cation in two different ways: first, subor dinates perceive that they share the same values as superiors, and the second subor dinates generate the desire to change their self-concept to be similar to the leader (Pratt, 1998).Leaders that perceived authentic by followers facilitate personal identification by connecting the self-concept of followers (Avolio et al., 2004).Authentic leaders rouse sense of personal identifi cation, deeper sense of personal commit ment and greater clarity about personal identity by setting personal example of high standars of integrity (Walumbwa et al., 2008).
The concept of social identity was introduced by Tajfel (1972), referring to the process of identifying a person to a group, being proud of group involvement, and feeling his membership towards a particular group is an important identity for him.Furthermore, social identity is the individual's key that he/she is part of a certain group, and emo tionally tied and perceive his/her membership is very valuable.
Based on social identity theory, Ashforth and Mael (1989) define social identification as belongingness to some human aggregate.This means that the higher the level of social identification a person has, the identification of his/ her social group will be more prominent in his/ her self-concept, assuming him/herself to have a fa bric and destiny with the group, regard group success as personal success.A person with a high social identi fication will direct his/her behavior according to group norms, and dedicate him/ herself to behave for the group's suc cess (Shamir et al., 2000).
Followers' identification with their organization occure when they feel pride in belonging to the group.Authentic leadership facilitate the emerge of this identity by expressing high value standard and honesty in their dealings with followers (Avolio et al., 2004).Employees who are willing to work hard, adopt change and take initiative when they personally identified them with the organization (Meyer et al., 2004).When followers value their leader's personality and spokes person for overall organization, they indulge in the process of personal and social identification (Javaid, 2015).According to Avolio et al. (2004) the behavior of followers (organiza tional identification) impact their organiza tion commitment as well (Javaid, 2015).
As already mentioned, authentic lea dership influences personal identi fication, social identification and trust to leader.It can be assume that authentic leadership directly and/or indirectly influence trust to leader with personal and social identi fication.Based on the evi dence from prior research and literature review, we argue that personal and social identification mediates the affect of authentic leadership to trust and organizational commitment.Thus, assert the following hypotheses on mediation: H3a: Personal identification medi ates the positive relationship between authentic leadership and trust to leader.H3b: Social identification mediates the positive relationship between authentic leadership and trust to leader.H4a: Personal identification mediates the positive relationship between authentic lea-dership and organizational commitment.H4b: Social identification medi ates the positive relationship between au then tic leadership and organizational commit ment.

Trust to Leader as a Mediating Variable
Clapp-Smith et al. ( 2009) stated that the more followers perceived their leaders are being true to themselves and behaving in accordance with their deeply held beliefs, the more followers may take a risk by offering further dedication to organization.In addition, followers who perceive their leader as being authentic are theorized to experience both greater levels of trust as well as development of their own capacities for authenticity and engagement in their work (Gardner et al., 2005).
It is difficult to display leader's ability unless a leader gets member's trust even though a leader has professional capability.The members who trust their leader tend to tell them the truth about the organization.Otherwise, while they do not feeling unfairly treated, it will decreases engage ment (Morrison & Robinson, 1997).Nota bly, employees' trust in a leader is the main factor causing individual attitude and behavior.In addition, trust brings more positive job attitudes and behaviors (Dirks & Ferrin, 2002) such as organizational commitment.
There is limited empirical research evidence in linking authentic leadership and trust as mediating effect (Avolio et al., 2004;Wong et al., 2010).Therefore, we suggest that authentic leadership will contribute to followers trust to leader and in turn result in an increased of organi zational commitment: H5: Trust to leader mediates the positive relationship between authentic leadership and organizational commitment.
Based on propositions from authentic leadership theory and review of the lite rature, we hypothesized that followers per cep tion of authentic leadership have direct positive effect on their organiza tional commitment and indirectly effect through personal identification, social iden tification and trust to leader (Figure 1).

METHOD
Respondent drawn from one of the private university in Yogyakarta Special Region.We used purposive sampling method.Respondent must have a mini mum of two years tenure in order to be included in the data analysis.Robinson et al. (1994) argued that perceived of employee's obligation to his or her organization dynamically changes within two years.Self-administered sur vey distri buted to 150 respondents and 140 returned (93.3% response rate).We had to drop eleven questionnaires because did not meet the minimum required working period.All items were measured on Likert-type scales from 1 (strongly disagree) to 5 (strongly agree).Because all the scales were originally developed in English and intended for use in Bahasa, we did translation and back-translation method.Before dis tri buted to res pon dents, translated questionnaire was con sul ted with an organizational behavioral expert.
Authentic Leadership was measured with nine-item adapted from The Authentic Leadership Questionnaire developed by Walumbwa et al. (2008) that explains four dimensions include (1) self-awareness, (2) rational transparency, (3) internalized moral perspective, and (4) balanced processing.Sample items include "My leader encourage everyone to speak their mind" and "My leader make difficult decision based on high standards of ethical conduct".The cronbach's α for this scale is 0.84.
Personal Identification was measured with four-item drawn from Identification with Leader Scale (Shamir et al., 1998).A sample item is "he represents values that are important to me".The cronbach's α for this scale is 0.82.To measure Social Identification, we used fouritem scale drawn from Organizational Identification Scale (Mael & Ashforth, 1992).A sample item is "this school success is my success".The cronbach's α for this scale is 0.77.
Trust to Leader was measured by fouritem adapted from The Trust In Management Scale (Mayer & Gavin, 2005).A sample item is "I have complete faith in the integrity of my manager".The cronbach's α for this scale is 0.85.In measuring Organizational Commitment, a five-item based on Organizational Commitment Questionnaire developed by Mowday et al. (1979).Sample items include "I am willing to put in a great deal of effort beyond that normally expected in order to help this organization be successful" and "I am proud to tell others that I am part of this organization".The cronbach's α for this scale is 0.79.
Corrected item-total correlation is used to test the validity, next step is calculate the cronbach alpha value as the reliability indicator for each variable.Item statement from the questionnaire will not be dropped if corrected itemtotal correlation value greater than 0.4 (Ladhari, 2010) and variables considered reliable if its cronbach alpha value greater than 0.6 (Hair et al., 2010).After performing the validity test, descriptive statistics, reliability estimates and Pearson's correlation are computed (Table 2) for all study variables.Path analysis was used to perform hypothesis testing.The four-step procedure from Baron and Kenny (1986) was also conducted to examine mediating effect in the model.Sobel test was applied to complement the mediating analysis test from previous procedure.

RESULT AND DISCUSSION
The profile of respondent is dominated by male (72.1%), with age above 45 years old (66.7%).Majority of education levels are high school gra duates (51.9%) and 64.3% of respondent have more than 20 years tenure.Face validity method used by asking the behavioral science expert to check tran slated items from English to Bahasa.The results of validity test using corrected total-item correlation for four-item trust to leader, five-item organi zational commit ment, and four-item personal identification showed that all items are valid (> 0.4 as cut-off value) (Ladhari, 2010).For authentic leadership measure ement, one item (AL5) was dropped because its value less than the cut-off, while for social identification variables, two item state-ments (SI3 & SI4) were dropped.Cronbach's α score is used to checked the reliability of the measures (≥ 0.70).Table 1 (listed in the diagonal in parentheses) shows that the cronbach's α score for each variable exceed the cut-off value 0.70.Thus, the items can be used for further analysis.
The means, standard deviations, and inter-correlation for the study variables are found in Table 1.The correlation between authentic leadership with others variables range from 0.747 to 0.411 (all p < 0.01).Respondent perceived their leader to be high score in authentic (M = 3.65).The organizational commitment sub scale was rated the highest (M = 4.05).One possibility that cause high score of organizational commit ment is high respondents tenure (> 20 years).Overall, respondents have a high score for personal identification, social identification, and trust to leader (average score > 3).
The result of pearson correlation between variables in Table 1 do not indicate a multicollinearity problem.Corre lation test results also indicate a signi ficant correlation between independent and dependent variables in this study, so that the model test with structural equation modeling can be proceed.

Result of Hypothesis Testing and Effect Estimates
Only standardized effect of coefficient is discussed here (Figure 1 and Table 2).Authentic leadership had a significant positive direct effect on personal identification (β = 0.698; p < 0.01) and social identification (β = 0.411; p < 0.01).As hypothesized authentic leadership had a significant positive di rect effect on trust to leader (β = 0.747; p < 0.01).Therefore, H1 is supported.From followers identification, only personal iden tification had a positive direct effect to trust to leader (β = 0.738; p < 0.01) but social identification had not significant direct effect to trust to leader.
In addition, there is no significant direct effect from social identification to organizational commitment, only personal identification had significant positive direct effect toward organi zational commitment (β = 0.471; p < 0.01).As hypothesized, authentic leader ship had significant positive direct effect on organizational commitment (β = 0.448; p < 0.01).Thus, H2 is supported.In addition, trust to leader also had significant positive direct effect on organi zational commitment with re gression coefficient β = 0.592 (p < 0.01).

Result of Mediating Analysis
In this study, we also examine mediating mechanism of authentic leader ship proposed by Avolio et al. (2004).According to Avolio et al. (2004) 'linking model, the relationship between authentic leadership and followers outcomes medi ated by the degree of personal and social identification with the trust in the leader.In addition, this study also examines organizational commitment as work atti tudes.
Causal four step approach was adopted to test mediating effect (Baron & Kenny, 1986).First, the relationship between authentic leadership to trust through personal identification was tested.The first step in the analysis here involved regressing authentic leadership to trust.The result presented in Table 2 shows a positive and significant affect (β = 0.747; p < 0.01).The second step in mediation analysis involve regressing authentic leadership to personal identification.Table 2 indicate positive and significant authentic leadership affect on personal identification (β = 0.698; p < 0.01).
The third step of the mediation analysis involve regressing personal identification to trust.Table 3 indicate positive and significant affect of personal identification on trust (β = 0.738; p < 0.01).In the final step of mediation analysis trust was regressed on authentic leadership and personal identification.As predicted, the result (Table 3 in step 4a) indicate that when personal identi fication was entered into the equation, the standardized beta coefficient of the relationship between authentic leadership and trust to leader remained significant but its value reduced (β = 0.46; p < 0.05).At the same time the effect of personal identification on trust to leader remained significant.It confirms the partial mediation effect of personal identification on the authentic leadership and trust.Therefore, H3a is supported.
Complementing the causal step approach, the Sobel test was conducted to determine the significance of the indirect effect of authentic leadership on trust through personal identification (Table 4).Calculation result with Sobel test confirm the mediating effect of personal identification (Z-value = 4.70; p < 0.001) in relationship between authentic leader ship and trust to leader.Furthermore, the values of the Aroian test and Goodman test (Table 5) also provide the same result.Therefore, indirect effect of authen tic leadership on trust through personal identification was confirmed.
We conducted identical step from mediating analysis before to test the relationship of authentic leadership to organizational commitment through per so nal identification.Jumped to final step of mediation analysis (Table 3 step  4b), organizational commitment was regressed on personal identification and authentic leadership.As predicted, the result indicates that when personal identification was entered into the equation, the positive effect of authentic Organi zational Commitment leadership to organi zational commitment is no longer signi ficant (β = 0.19; p > 0.05).At the same time the effect of personal identification on organizational commitment remained significant.Therefore, it confirms that personal identification fully mediated the effect of authentic leadership on organi za tional commitment.The result of Sobel test confirm the mediating effect of personal identification (Z-value = 5.57; p < 0.001) and also the two other tests show the same result (Table 7).There fore, hypothesis 4a is supported.
A similar four-step mediation ana lysis was applied to test the relationship of authentic leadership to organizational commitment through trust to leader.At the final step of mediation analysis (Table 3 step 4d) organizational commitment was regressed on authentic leadership and trust to leader.The result (Table 4 step 4d) showed that when trust to leader was entered into the equation, the positive effect of authentic leadership to organiza tional commitment is no longer signi ficant (β = 0.01; p > 0.05).At the same time the effect of trust to leader on organizational commitment remained significant (β = 0.58; p < 0.05).There fore, it confirms that trust to leader fully mediated the effect of authentic leader ship on organizational commitment.The result of Sobel test also confirms the result (Zvalue = 7.77; p < 0.001) and also the two other tests show the same result (Table 6).Therefore, hypothesis 5 is supported.
There are actually other authentic leadership mediation hypotheses that involve social identification.We did not conduct further analysis because the basic assumption of mediation analysis based on Baron and Kenny (1986) is not met.As shown in Figure 1, social identification has no significant direct effect on both trust to leader and organizational commitment (Table 2).Thus, automatically H3b and H4b that state social identification has a mediating role in authentic leadership model is rejected.
Although we have not previously stated in hypothetical form, we also examine the possibility of mediating role comes from trust to leader in relationship between personal identification and organizational commitment.We also conducted identical step from mediating analysis before jump to final step of mediation analysis (Table 4 step 4c) organizational commitment was regressed on personal identification and trust to leader.As predicted, the result (Table 4 step 4c) indicate that when trust to leader was entered into the equation, the positive effect of personal identification to organizational commitment is no longer significant (β = 0.15; p > 0.05).At the same time the effect of trust to leader on organizational commitment remained significant.Therefore, it confirms that trust to leader fully mediated the effect of personal identification on organiza tional commitment.The result of Sobel test confirms the mediating effect of trust to leader (Z-value = 7.78; p < 0.01) and also the two other tests show the same result (Table 5).
As stated in previous analysis of H1, this study found the positive and significant direct effect of directly and indirectly (through personal identifi cation) affect trust to leader.This finding is similar with study from Wong et al. (2010) and Clapp-Smith et al. (2009).When followers perceive that their leaders are authentic, they also will believe they can trust those leaders.These findings are in line with Wong et al. (2010).Further, increased trust was positive and significantly related to organizational commitment.In this study, we confirmed positive and direct effect of authentic leadership to organizational commitment on H2.This fin ding consistent with Walumbwa et al. (2008) and Rego et al. (2016).
Support for H5 provides additional empirical test of the relationship between authentic leadership on both trust to leader (H1) and organiza tional commitment (H2).Authentic leadership directly and indirectly affect trust to leader and organizational commitment.It confirmed that trust to leader actively mediating the relationship between authentic leadership to organi zational commitment.Trust has been suggested as a mediator to perfor mance for many leadership theory (Clapp-Smith et al., 2009).
As hypothesized, H3a and H4a show that personal identification mediated the relationship between au then tic leadership and its outcomes.This finding is in line with prior studies, shows that personal identification has a role as mediating variable between authentic leadership and employees attitudes (Wong et al., 2010;Liu et al., 2015).Contrary to what we hypothesized and proposition by Avolio et al. (2004), follower's social identification with their organization does not indicate its role as mediator for the relationship between authentic leadership to organizational commitment and trust to leader (H3b and H4b rejected).
The direct effect of social identification to trust and commitment was not found.These findings is similar to Kark et al. (2003) and Wong et al. (2010) in case of transformational leadership to social identification.Some alternative explanations may be the cause of it.
Social identification means the extent to which individuals feels sense of belonging and identifies themselves with their work group.According to the theory of social exchange, the golden rule that makes the employee feel obliged to reciprocate favorable attitudes towards them into trust and commitment sourced from leaders who represent the orga nization.We suspect that the absence of the influence from social identification to organizational commitment and trust caused by the role of social identification is bigger in social life of the respondent with the working group.Organizational commitment and trust in leaders place a leader as represent of organization as the object or target of employee commitment and trust.Social identification variables are thought to have no direct effect because the source of social identification is not directly related to the organization, such as co-workers, working atmosphere, or emotions related to the company's external environment.

CONCLUSION AND RECOMMENDATION
The main objective of this study is to investigate the effect of authentic leadership on several important variables by proposing a theoretical linking model from Avolio et al. (2004) includes personal identification, social identification, trust to leader, and organi zational commitment in a higher edu cation staff.Majority of our findings support the theoretical framework build by Avolio et al. (2004).Personal identification and trust to leader connect authentic leadership to its consequences.We found that the authentic leadership affect employee to identify with him/her self could emerge trust and commitment.With increasing challenge for higher education institution to enhance competitive advantage and address global challenge and also of course the rapid dynamic change of business world, authentic leadership can be great alter native to provide positive direction for higher education and best leadership practices to optimize and continuously improve the quality and its outcomes.
These findings suggest a number of practical implications for managers.In order to promote and enhance follower's commitment and trust, leaders can apply the advantages of authentic leadership by applying their four dimensions, which is sharing information, being open and truthful to staff, ask for feedback from the staff, and actively involving staff to decision ma-king while point out the importance of ethical standard in these processes.Leaders also actively set an example for followers, expressing true feelings, and genuinely build leader-follower good relation.Even though this research has theoretical contributions and practical implications, there are some limitations to this study.
First of all, we gathered the respondent from employees working in one of higher education in Yogyakarta special region, and this requires caution for interpreting the findings of the study.It is recommended for further studies to test the model in several regions to generalize the findings better.
Second, this study is about leader of higher education insti tution, big possibilities there may be different results from the study on leaders in various type of organization.Further research should examine leadership in several types of organization or industries to better capture the phenomena.
Third, we do not distinguish respondents into specific categories.While responses to organizational commitment and trust may differ for employees of a particular background (i.e.responses may differ between educators such as lecturers and non-academic employees, based on posi tion or hierarchy, upper level employees and lower level employees have different response).Future research may be required for multi-group analyses to investigate the differences among employee groups.
