Abstract Motivation is an important feature of emotion. By driving approach to positive events and promoting avoidance of negative stimuli, motivation drives adaptive actions and goal pursuit. The amygdala has been associated with a variety of affective processes, particularly the appraisal of stimulus valence that is assumed to play a crucial role in the generation of approach and avoidance behaviors. Here, we measured amygdala functional connectivity patterns while participants played a video game manipulating goal conduciveness through the presence of good, neutral, or bad monsters. As expected, good versus bad monsters elicited opposing motivated behaviors, whereby good monsters induced more approach and bad monsters triggered more avoidance. These opposing directional behaviors were paralleled by increased connectivity between the amygdala and medial brain areas, such as the OFC and posterior cingulate, for good relative to bad, and between amygdala and caudate for bad relative to good monsters. Moreover, in both conditions, individual connectivity strength between the amygdala and medial prefrontal regions was positively correlated with brain scores from a latent component representing efficient goal pursuit, which was identified by a partial least square analysis determining the multivariate association between amygdala connectivity and behavioral motivation indices during gameplay. At the brain level, this latent component highlighted a widespread pattern of amygdala connectivity, including a dorsal frontoparietal network and motor areas. These results suggest that amygdala-medial prefrontal interactions captured the overall subjective relevance of ongoing events, which could consecutively drive the engagement of attentional, executive, and motor circuits necessary for implementing successful goal-pursuit, irrespective of approach or avoidance directions.

This research is a quantitative study that aims to determine the Millennial Generation Characteristics of Employee Engagement. The population in this study The study was conducted by taking samples of Millennials who are actively working at Micro Finance companies with a total of 150 respondents. The sample size was taken as many as 150 respondents, with probability sampling methods especially simple random sampling. Data collection was carried out through questionnaires. The analysis technique used is the PLS (Partial Least Square) analysis method. The results of this study indicate that the value of R- Square (R2) Employee Engagement is 0.786 and Employee Satisfaction is 0.647 thus indicating that the contribution of Grit, Worklife Balance, and Jon Resources variables to Employee Engagement and Employee Satisfaction are 0.786 or 78.6% and 0.647 or 64.7%. And the rest is influenced by other factors not examined.

<p>This research is a quantitative study that aims to determine the effect of financial literacy, financial technology, income, and locus of control on financial behavior. The population in this study were Lecturers at the Universitas Pembangunan Nasional Veteran Jakarta. The sample size was taken as many as 80 respondents, with methods through nonprobability sampling, purposive sampling. Data collection was carried out through questionnaires. The analysis technique used is the PLS (Partial Least Square) analysis method with SmartPLS 3.0 software. The results of this study indicate that (1) financial literacy has a significant positive effect on financial behavior. (2) financial technology has no influence and is not significant in financial behavior. (3) income has a significant positive effect on financial behavior. (4) locus of control does not influence financial behavior.</p>

Micro enterprises formed the majority of business establishments in Malaysia and play an important role in the business ecosystem. There are numerous studies of intellectual capital on large organizations and small and medium enterprises, however no study has been carried out on micro enterprises. The findings of the partial-least square analysis of one hundred and six micro enterprises found that intellectual capital has a significant relationship to organizational performance. In addition, the relationship between intellectual capital and organizational performance was significantly influenced by tacit knowledge sharing. In particular, tacit knowledge sharing proves to be extremely relevant when it comes to reinforcing the intellectual capital on the performance of micro enterprises in Malaysia. Limitations and implications for future studies are discussed.

To trigger consumer transactions in order to buy a certain product and encourage aggressive purchasing decisions. One trick is that promotion is able to stimulate demand for a product. With the promotion, it is expected that consumers will want to try these products and encourage existing consumers to buy products more often so that re-purchases will occur and the sales volume of a company's products will increase. Promotion is an important factor in realizing the sales goals of a company. In order for consumers to be willing to subscribe, they must first be able to try or research the goods produced by the company, so that buyers can be sure of these goods. Targeted promotion is expected to have a positive effect on increasing sales. Promotion is an important aspect of marketing management and is often said to be a continuous process. With promotion, people who are not interested in buying a product will be interested and try the product so that consumers make a purchase. The type of promotional mix is ​​the combination of the best strategies from the variables of advertising, personal selling, and other promotional tools, all of which are planned to achieve the goals of the sales program. This study aims to examine the effect of promotion on glove purchasing decisions. Respondents of this study used 150 research samples at various hospitals, namely doctors and health workers, the tools used in this study used the PLS (Partial Least Square) analysis method. The results of this research are the effect of promotion on purchasing decisions accepted.   Keywords: Sales Promotion, Purchasing Decision

The purpose of this study is to determine the effect of perceived value on trust and repurchase intention, the effect of trust on repurchase intention, and to determine the role of trust in mediating the effect of value perception on repurchase intention on Green coffee in Denpasar City. The population of this study are consumers of Green coffee products in Denpasar City. The samples of this study are Green coffee consumers residing in Denpasar City. The method to determine the sample used in this study is purposive sampling which is a data source sampling technique with certain considerations. The number of sample used is 100 who lives Denpasar City that have consumed Green coffee. PLS (Partial Least Square) analysis techniques is used to analyse the data. The results of this study indicate that value perception ??and beliefs have a positive and significant effect on Green coffee repurchase intention; value perceptions have a positive and significant influence on trust; and trust positively and significantly mediates the effect of perceived value on consumers' repurchase intention towards Green coffee in Denpasar City.

Abstract The main objective of the present study was to establish significant and validated QSAR models for imidazoles and sulfonamides to explore the relationship between their physicochemical properties and antidiabetic activity. Two dimensional QSAR models had been developed by multiple linear regression and partial least square analysis methods, and then validated for internal and external predictions. The established 2D QSAR models were statistically significant and highly predictive. The validation methods provided significant statistical parameters with q2 > 0.5 and pred_r2 > 0.6, which proved the predictive power of the models. The developed 2D QSAR models revealed the significance of SlogP and T_N_O_5, and Mol.Wt and SsBrE-index properties of imidazoles and sulfonamides on their antidiabetic activity, respectively. These results should prove to be an essential guide for the further design and development of new imidazoles and sulfonamides having better antidiabetic activity.
