This study modeled knowledge hiding as a formative second-order construct that consists of three dimensions of evasive hiding, playing dumb, and rationalized hiding respectively. First, the collinearity test of VIF demotes that the related dimensions are independently forming knowledge hiding behavior. Furthermore, we tested the lower and higher weights of each first-order dimension that aims to reveal the different propensity of knowledge hiding categories. The bootstrapping results illustrated that all three first-order constructs were significantly related to knowledge hiding. Thus, this model included with knowledge hiding is a reflective-formative type II model (Becker et al., 2012) (as shown in Table 3).

Defensive silence and defensive voice measurements were adopted from Dyne et al. (2003), each with five items ranging from (1) “strongly disagree” to (5) “strongly agree” have been applied in this study.

Even though the diffraction effect is known for more than 300 years, DOEs have only started to be used more widely in the last few years. Today, the applications range from security features on banknotes to beam shapers for laser welding and multifocal microscopy lenses, to name just a few. DOEs are very attractive because they can create light patterns of almost any shape from a simple laser beam while being flat and thin plus offering high efficiency.

This study proposes that defensive silence and defensive voice result in counterproductive work behavior by conducting knowledge hiding behavior. In other words, knowledge hiding represents the mediating role of the relationships between defensive traits and negative organizational dynamics. Rooted in SOR, knowledge hiding was stimuli by defensive silence when employees conceal the desire of expression, and often seen as self-protection from negative social opinions. Analogously, defensive voice is conceived as unwilling to attract attention within the group rather than invading others’ cognitive superiority (Unler and Caliskan, 2019). Based on the defensive bondages, employees gained decreased intrinsic drive to disseminate knowledge. Both defensive silence and defensive voice breach employees’ psychology safety (Detert and Burris, 2007; Jiang et al., 2019) that undermines the trust between knowledge disseminators and knowledge recipients. Thereafter, knowledge hiding blocks the chain of knowledge dissemination (Losada-Otálora et al., 2020), leading to a colossal waste of human capital toward the unfavorable work attitude of counterproductive work behavior. Thus, we propose that:

DOEs are powerful optical elements offering possibilities that are not able to be achieved with any other refractive optical element. But their proper use and implementation needs to be carefully considered, and the fabrication method needs to match the requirements of the application. Helbling can provide support with know-how in the field of refractive and diffractive optics, optical design capabilities, and experience in product development.

The present study deepens the predictors of knowledge hiding and indicates its related outcome of counterproductive work behavior through the lens of stimulus-organism-response (SOR). Meanwhile, this study contributes to knowledge hiding literature in various ways. First, specifying the differences of silence and voice under defensive behaviors enables the application of SOR to better explore the antecedents of knowledge hiding. Second, examining the negative consequence of counterproductive work behavior with attempting empirical validation is pressed for further deterrent measures. Third, academic knowledge workers should gregariously self-assured the benefits from ecology-based knowledge setting in the quest for coexistence.

Knowledge hiding was according to Connelly et al. (2012) with five dimensions: evasive hiding, playing dumb, rationalized hiding, lack of sharing, and knowledge hoarding. This study adopted three dimensions of evasive hiding, playing dumb, rationalized hiding to investigate the knowledge hiding behavior within academic relationships. A total of 12 items have been applied through the seven-point Likert scale which is ranging from “strongly disagree” to “strongly agree.”

Stimulus emphasizes the outer environment that is outlined by organizational competence climate to influence the defensive traits of employees. Defensive silence and defensive voice are on describing employee withhold expression because of the fear of negative social opinions. Hence, defensive silence and defensive voice as the predictors of knowledge hiding obtained theoretical support from the role of stimulus.

The digitalization of diversified information channels portrays volatile knowledge management due to suspicious processing capability and unanalytical elaboration (Fan et al., 2021; Trittin-Ulbrich et al., 2021). However, both individuals and organizations are primarily dependent on the competitive advantage of knowledge management to cope with the dynamic and uncertain environment. The current workplace characterized by increasing competition and decreasing knowledge sharing seeks to dissect the potential risk into the formation of knowledge hiding (Anand et al., 2021). Researchers conceptualize counterproductive knowledge behavior as individuals who intend to conceal knowledge for group members in need (Connelly et al., 2012; Connelly and Zweig, 2015). Hence, investigating the antecedents and consequences of knowledge hiding has gained increased prominence in the priorities of knowledge institutions.

The measurement content applied in this study was validated through pre-testing to reduce the response bias, all of the measures were finalized by the means of back-translation procedures (Brislin, 1980). The current sample consists of 460 knowledge workers in Chinese academic institutions. About 57.4% of them are men, 42.6% are women. The largest age group is 36∼45 years old (37.2%). In the terms of educational background, 58.3% of them graduated as masters and 39.6% of them are Ph.D. There are 37% of academic knowledge workers worked less than 5 years. The sciences study field occupies 55.7% compared with the arts study field 44.3%.

The measurement model was assessed through convergent validity, discriminant validity, and reliability. As indicated in Table 1 and Figure 2, all the measurements’ loadings surpassed 0.40 (Hair et al., 2013) and exceeded the cut-off value of average variance extracted (AVE) (Fornell and Larcker, 1981), implying sufficient convergent validity. In addition, the composite reliability of each construct was above the suggested threshold of 0.708 for achieving expected construct reliability (Hair et al., 2013). Another assessment of discriminant validity has been proven through the heterotrait-monotrait ratio of correlations (HTMT) (as shown in Table 2). HTMT was used to estimate the factor correlation and upper limit (Henseler et al., 2015).

The theoretical foundation of this study is drawn on the SOR (Mehrabian and Russell, 1974). Rooted in environmental psychology, SOR assumed the outer environment as the stimuli (S) that lead to internal organism (O), which shape the people’s behavior response (R). This model based on SOR was extensively developed to deepen the understanding of knowledge hiding results from defensive silence and defensive voice in emphasizing the negative consequence of counterproductive work behavior.

Given previous literature by Connelly et al. (2012), this study empirically validated knowledge hiding as a formative second-order construct that compromises essential ingredients as evasive hiding, playing dumb, and rationalized hiding. The finding suggests that playing dumb is the most significant contributor to knowledge hiding with the highest weightage, followed by evasive hiding and rationalized hiding. The multidimensional construct enables to differentiate various hiding behaviors based on holistic understanding.

Computer models that simulate light patterns are used to determine the required microstructures for a DOE. But modeling DOEs is difficult due to their large number of microstructures distributed over their macroscopic size. Ray tracing, the most commonly used tool for refractive optics, does not take diffraction effects into account. Simulating wave propagations fully from each microstructure over the entire DOE requires a huge amount of computational power. Therefore, suitable modeling methods for DOEs rely on making simplified assumptions.

The versatility of DOEs sparks the creation of innovative products. For example, an active intraocular lens containing a DOE was developed in a collaboration between Helbling and Elenza, an innovative American medtech start-up. Artificial intraocular lenses are used to treat cataracts. In most cases, monofocal lenses are used, which only enable the patient to see sharp images at one distance and still require a pair of glasses to see at the other distance. Combining a DOE with a liquid crystal cell allows the optical power to be switched automatically simulate the natural accommodative ability of the lens of the eye.

Thin-element approximation (TEA) is very frequently used since it enables fast simulation with low memory requirements. This method assumes that the light only changes its phase while passing through the DOE but not its direction. It works well for thin DOEs and small light angles but gives faulty results in other cases.

Academic knowledge workers in academic institutions are often involved in high intensive knowledge activities (Ghani et al., 2020). The main factors that formed knowledge hiding initially become urgent problems to be reckoned with, which would foster greater knowledge interactivity to enhance both sustainable academic and research performance (Chen et al., 2021). Despite this, there was rare research which reveals knowledge hiding toward counterproductive work behavior being fully implemented by knowledge workers.

Response as the main purpose to develop SOR, describing stimulus and organism may simultaneously lead to significant changes in response. The response converts to behavior, intention, decision, and choice. A number of researchers have examined responses, such as behavior (Kim and Moon, 2009; Siu et al., 2012) and affect (Daunt and Harris, 2012). This study considered counterproductive work behavior as response to investigate how defensive employees conceal knowledge because of fear to express opinions.

The structural equation modeling (SEM) analysis comprises measurement model and structural model by applying Smart partial least square (PLS) (Ringle et al., 2015). Common method bias (CMB) associated with the cross-sectional collection panel was based on the different scales of single source data. First, an unmeasured marker variable was used to access the changes of R2 value after an extra construct arrowed into the research model (Malhotra et al., 2006). The marker variable involved in the difference of R2 value on the endogenous construct of CWB is 1.1%, which is much less than 10%. Second, according to Kock and Lynn (2012), we tested variance inflation factor (VIF) to eliminate the full collinearity issue. The VIF values of underlying constructs are lower than the threshold of 3.3 (Diamantopoulos and Siguaw, 2006). Overall, the above steps may prove that CMB is not a concern in this study.

Theoretically, this study validates the SOR model to enrich the existing literature of knowledge hiding, justifying the significant predictors of defensive silence and defensive voice as stimulus (S), knowledge hiding as organism (O), and CWB as response (R) among academic knowledge workers. Findings obtained from this study indicated that knowledge workers with defensive behaviors caused by competitive stress or lack of psychological safety are fear to propose their ideas, information, and suggestions, which are used to avoid potential disputes from external environment. Consequently, academic knowledge workers tend to act CWB through knowledge hiding that impedes knowledge-oriented performance, such as reducing effective knowledge dissemination, leading to inefficient knowledge reciprocation. Hence, SOR in conjunction with the mediating role of knowledge hiding has been supported from the role of response.

The findings of this study have three implications for practicing managers. First, both defensive silence and defensive voice lead to knowledge hiding, which have the detrimental effects on knowledge management. To better encourage knowledge workers from defensive traits, organizations or academic institutions may improve the team psychological safety climate (Qian et al., 2020) and team mastery climate (Černe et al., 2017) through co-creation positive working attitude for fostering knowledge sharing. Second, knowledge hiding exerts the mediating role on CWB. Organizations may process reward systems (Bock et al., 2005), place support on prosocial motivation (Škerlavaj et al., 2018), and ingrain knowledge sharing among academic knowledge workers. Finally, this study shows the consequence of knowledge hiding on CWB, the crucial role of knowledge-oriented leadership might be highlighted to enhance work enthusiasm and professional ethics (Donate and de Pablo, 2015).

DOEs are usually made as thin plates with microstructures on the surface that cause diffraction effects. These structures can have smooth or step profiles, which define the light pattern behind the DOE.

Organism is associated with knowledge hiding consisting of evasive hiding, playing dumb, and rationalized hiding. Although organism was considered as the important connection part in an SOR model, much remains unknown about employees’ activities that link the relationship between stimulus and response in the knowledge management of academic institutions (Zhai et al., 2020). In this study, knowledge hiding driven by defensive traits on fear to express examined the role of organism in concealing knowledgeable information to workplace members.

The bootstrapping method with 5,000 samples was applied in the hypotheses testing. We found that the positive significant relationship between defensive silence and knowledge hiding (ß = 0.267, t = 4.880, p < 0.001); the positive relationship between defensive voice and knowledge hiding (ß = 0.202, t = 3.785, p < 0.001); the positive relationship between knowledge hiding and CWB (ß = 0.440, t = 10.600, p < 0.001). Apart from direct relationships, an indirect relationship of mediation analysis has been supported. The significant mediating role of knowledge hiding exists between defensive silence and CWB (ß = 0.118, t = 4.160, p < 0.001); the significant mediator of knowledge hiding links defensive voice and CWB (ß = 0.089, t = 3.569, p < 0.001). Hence, H1, H2, H3, H4, and H5 are all supported and consistent with our prediction (as shown in Table 4).

Knowledge economy strategically represents the label of productive forces, as reflected in the pioneers through various industries (Di Vaio et al., 2021). Furthermore, academic knowledge workers have been undertaken voluntary initiatives to the academic civilization and social cognition by knowledge behavior (Ramayah et al., 2014). However, many academic knowledge workers engage in knowledge hiding due to scarce psychological safety (Men et al., 2020), which leads to undesired productive consequences. Literature suggests that knowledge hiding results in counterproductive work behavior wherein employees feel distrust and then inconsistent with a reciprocal role in organization (Arain et al., 2020), adversely affecting their well-being (Khoreva and Wechtler, 2020). Employees who conduct knowledge hiding behaviors may lower task performance (Xiong et al., 2019) by workplace deviance (Singh, 2019). Even though the negative consequences of knowledge hiding have been explored by foregoing discussion, rare empirical study highlights the counterproductive work behavior in academic setting. Therefore, this study accordingly predicts that:

Rising negative emotions are like “time bombs” that impede productivity in the workplace. The present investigation provides an insight into the effects of defensive silence and defensive voice on counterproductive work behavior through knowledge hiding in the context of knowledge workers in Chinese academic institutions. Partial least square structural equation modeling (PLS-SEM) was applied to the current samples. The study obtained conjecture the proposed mediating role of knowledge hiding between the negative working attitude and counterproductive work behavior, which is against the organizational norms and performance. The result indicates that the positive relationships exist from defensive silence and defensive voice to counterproductive work behavior, mediated by knowledge hiding. This study links knowledge hiding literature and stimulus-organism-response (SOR) to better explore the academic behavior in a knowledge setting.

Defensive silence has been characterized as employees purposely withholding ideas, information, and suggestion at work-related expression (Dyne et al., 2003). Various reasons behind defensive silence have been further explored in knowledge hiding literature. Pinder and Harlos (2001) highlighted employee silence associated with injustice, explaining the reason why employees withhold information. Jahanzeb et al. (2020) elucidated organizational injustice increase knowledge hiding because employees feel disconnected from the organization’s identity. Moreover, many studies revealed psychological safety as the main lens to knowledge behavior, enforcing work focus and reducing worries (Jiang et al., 2019), and boosting harmonious interpersonal trustful climate. On the contrary, scant psychological safety trigger knowledge hiding when employees suffer from intragroup relationship conflict (Peng et al., 2020) and competition (Semerci, 2019). Employees do not express themselves due to psychological insecure that fear negative repercussions. Since limited knowledge management research investigated the defensive silence as the antecedents of knowledge hiding, we propose that:

Mediation analysis in both paths provides support for the arguments above. This study drew on SOR to justify when knowledge workers perceived defensive traits (e.g., defensive silence and defensive voice), they may have direct response to CWB through knowledge hiding (H3 and H4). Knowledge hiding explained the mechanism from employees’ fear to express toward floppy working attitude. The consequence of knowledge hiding on CWB draws attention for academic knowledge workers (H5). When employees feel misfit with organizational identity, they are more likely to engage in knowledge hiding due to distrust (Zhao et al., 2019). Failing in connecting with the organizational identity, CWB is governed by deficient goals and beliefs (Götz et al., 2020). Hence, a positive relationship exists between knowledge hiding and CWB.

Considering the several current limitations may leave avenues for potential future attempts. First, the sample limits the generalizability to solely focus on the context of knowledge workers in Chinese academic institutions. Future studies may conduct cross-cultural research to compare the cultural-oriented factors that affect knowledge hiding behavior. Second, although the limitation regarding cross-sectional design is avoided by several tests, such studies could yield longitudinal design to expand causality. Third, specifics related to other boundary conditions and derived by personal differences could be further explored, investigating the potential phenomenon. In addition, further study may investigate knowledge management leadership within a participative climate to enhance the effective knowledge implementation (Pellegrini et al., 2020).

Defensive voice entails the perceptions of employees intentionally expressing the agreement rather than radicalizing against group (Dyne et al., 2003). Defensive voice focuses on the positive aspect of work-related information rather than accounting for the flaw in problems, diverting attention from workplace criticism. Alternatively, employees typically tend to protect themselves from negative social opinions by refraining from showing their knowledge ability and quality. On this basis, knowledge hiding behavior refers to the concealing or partially sharing knowledge to recipients is motivated by the traits of defensive voice. Meanwhile, the strong effect of leadership on voice behavior decides how employees speak out their opinions with psychological safety (Detert and Burris, 2007). Dark leadership, such as exploitative leadership (Guo et al., 2021) and abusive supervision (Khalid et al., 2018; Pradhan et al., 2019) indulge in interpersonal injustice that employees are involved in aggressive knowledge hiding by defensive voice. Therefore, exploring the defensive voice as a predictor of knowledge hiding remains a significant domain. We hypothesize that:

Understanding the requirements of your application and how they affect the DOE design is critical for successful product development. Important aspects to consider include target cost per device, production volume, required quality, and the operating environment. The characteristics of the light source (wavelength, optical power, etc.) also play a major role in the DOE design. These various aspects inform the selection of the DOE material (glass, plastic, etc.), the fabrication technology (photolithography, injection molding, etc.), and the optical design (step profile, smooth profile, element thickness, etc.). As a neutral partner, Helbling can evaluate the different options independently and select the most suitable material and fabrication process.

In the current study, we address an underexplored boundary condition in the knowledge hiding literature by differentiating defensive silence and defensive voice in understanding focal reasons. The results are congruent with previous literature, which found a positive relationship between defensive silence and knowledge hiding (H1). While employees’ defensive silence influenced by weakened psychological safety evokes employees in knowledge hiding (Semerci, 2019). Besides, workplace ostracism dampens the employees’ beliefs and confidence so that they fortify the potential threat by defensive silence (Chenji and Sode, 2019). Knowledge hiding derives from workplace ostracism highlights the significant role of moral disengagement (Zhao et al., 2016), specifically explaining the link between defensive silence and knowledge hiding. Another finding appears to be that defensive voice for personal purpose at work shows a positive relationship with knowledge hiding (H2). Since defensive voice avoids the idea related to innovation and improvement, erecting a barrier to knowledge management.

In this study, academic knowledge workers with defensive traits (defensive silence and defensive voice) would easily trigger knowledge hiding behavior due to the fear of invading others’ cognitive superiority and disclosure deficiency, which leads to counterproductive work behavior through the disconnect with organizational identity (see Figure 1).

In essence, the radicalized knowledge hiding mirrors unfavorable strategic position as it leads to less team creativity (Fong et al., 2018), contentious work relationships at organizational level through interpersonal conflict (Losada-Otálora et al., 2020), and deviance (Singh, 2019) by considering the employees’ job attitude on empowerment (Offergelt et al., 2019). Therefore, negative emotions related to job attitude can be commonly deemed to be the source of knowledge hiding (Yao et al., 2020b). Even though previous studies have discussed the reasons for knowledge hiding, such as gossip (Yao et al., 2020a), work incivility (Irum et al., 2020), and workplace ostracism (Zhao et al., 2016), limited studies have been conducted to explore the links between both defensive silence and defensive voice to knowledge hiding. This study aimed to fill this literature gap in the context of academic knowledge workers in China.
