This study aims to provide the best estimate of a stock's next day's closing price for a given day with the help of the hidden Markov model–Gaussian mixture model (HMM-GMM). The results were compared with Hassan and Nath’s (2005) study using HMM and artificial neural network (ANN).

The study adopted an initialization approach wherein the hidden states of the HMM are modelled as GMM using two different approaches. Training of the HMM-GMM model is carried out using two methods. The prediction was performed by taking the closest closing price (having a log-likelihood within the tolerance range) to that of the present one as the closing price for the next day. Mean absolute percentage error (MAPE) has been used to compare the proposed GMM-HMM model against the models of the research study (Hassan and Nath, 2005).

Comparing this study with Hassan and Nath (2005) reveals that the proposed model outperformed in 66 out of the 72 different test cases. The results affirm that the model can be used for more accurate time series prediction. Further, compared with the results of the ANN model from Hassan's study, the proposed HMM model outperformed 24 of the 36 test cases.

The study introduced a novel initialization and two training/prediction approaches for the HMM-GMM model. It is to be noted that the study has introduced a GMM-HMM-based closing price estimator for stock price prediction. The proposed method of forecasting the stock prices using GMM-HMM is explainable and has a solid statistical foundation.

Drawing on goal orientation theory, this study intends to investigate whether, how and when developmental leadership influences employees’ feedback seeking behavior (FSB) and feedback avoidance behavior (FAB).

The authors used a two-wave survey of 416 full-time employees in China. The hypotheses were tested with path analyses.

Developmental leadership exerts a positive influence on employees’ FSB and a negative impact on FAB through learning goal orientation (LGO). Additionally, leaders’ high performance expectations (LHPE) not only strengthen the positive effects of developmental leadership on FSB but also intensify its weakening effects on FAB.

The findings enrich current understanding by associating developmental leadership with employees’ FSB/FAB, offering a new viewpoint on its positive impacts. This study also provides deeper insights into when the benefits of developmental leadership are intensified.

The purpose of this study is to investigate the effects of leaders' managerial coaching on followers' organizational citizenship behavior (OCB), creativity and task performance. This study also examined the mediating role of intrinsic motivation and self-efficacy, recognizing the follower’s attitude and cognition as essential elements of behavioral changes.

This study collected data from 20 companies across multiple industries in South Korea, and a total of 386 leader–follower dyads' data were used.

The results show that leaders' coaching is positively associated with OCB directly, but a direct impact of coaching on creativity and task performance was not supported. The results also showed that intrinsic motivation partially mediates the effect of coaching on OCB and fully mediates the effect of coaching on creativity and task performance. Self-efficacy played a role as a full mediator between coaching and task performance.

This study considered both the cognitive and affective aspects of managerial coaching and examined the influence of managerial coaching on the followers' in-role and extra-role behaviors (i.e. OCB, creativity and task performance) using responses from both the leaders and the followers at multiple organizations. Specifically, the results of this study empirically illustrated that managerial coaching by leaders serves as a mechanism mediated through intrinsic motivation and self-efficacy, linking to employees' OCB, creativity and task performance. This provides a clear explanation of the processes through which managerial coaching impacts employees and offers insights into the specific aspects that organizational leaders should focus on when engaging in managerial coaching.

Construction management researchers have acknowledged that the use of buildability could improve outcomes of project. Efficient use of resources required for the procurement of construction projects is important for the economy. This study aims to aggregate the current knowledge on buildability within the construction management domain into an understandable whole using the systematic review approach.

An interpretivist epistemological approach was used as a lens for the systematic review of published research on buildability. The selected articles cover the time period between 1987 and 2020. The articles published in 2021 and 2022 were excluded to ensure that the scope of the current study is distinct and clear. In this research, qualitative content analysis was used to scrutinise the selected journal papers.

Based on the analysis of literature, the trends and gaps in the current knowledge on the topic of interest were identified. It was found that stakeholder’s knowledge and commitment play a huge role in the extent of adoption of buildability as a practice in the construction sector. Also, the study confirms that the use of buildability is beneficial to the project and its stakeholders.

The study maps the current state of knowledge on buildability and provides information on the gaps that could be explored in the future by researchers.
