This study examined how inclusive leadership in the workplace promotes proactive behavior in employees based on self-determination theories and a model of motivation for proactive behavior.

Using a sample of 270 employees from various provinces in China, we investigated the relationship between inclusive leadership (measured at Time 1), workplace gratitude (measured at Time 1) and proactive behaviors (measured at Time 2). To test our hypotheses, SEM analysis was conducted to measure the path coefficients, followed by bootstrapping analysis to assess the indirect impacts of gratitude at work.

The results suggest that inclusive leadership could enhance subordinates’ propensity to be grateful, which in turn will increase the frequency of their proactive behaviors.

First, the evidence presented further validates the proposed association between inclusive leadership and proactive behavior, and it also enriches related theories. Second, our study introduced workplace gratitude as a mediator, deepening the understanding of the mechanisms linking inclusive leadership and proactive behavior.

This paper aims to examine the effect of product market competition on firms’ unethical behavior (FUB) in the Chinese insurance industry and to further explore the boundary conditions of the main effects. On the basis of China’s commercial foundation, the study constructs a conceptual framework of FUB by drawing from the perspective of horizontal competition.

Data were collected from 52 property insurance firms at the branch level observed over the six-year period, 2011-2016. Within this framework, market power and market concentration were used to describe product market competition at firm and industry levels, respectively. The moderating effect of market munificence was analyzed to reveal the theoretical boundaries of the main effect. By drawing upon cost–benefit analysis and social network theory, the study used negative binomial model and Poisson model to quantitatively examine the relationship.

The relationship between product market competition and FUB is curvilinear. Especially at the firm level, market power exhibits a U-shape relationship with FUB; at the industry level, market concentration exhibits a U-shape relationship with FUB. In addition, market munificence positively moderates the impact of firm’s market power on FUB, whereas, market munificence negatively moderates the impact of industrial market concentration on FUB.

This paper explored a new type of unethical behavior that concerns consumers or the third party by emphasizing horizontal competitive contexts; it also provides a better understanding of the FUB–financial performance relationship from the perspective of competition. The moderating effects suggest that when the cause of FUB is different (market power vs market concentration), firms may make opposite ethical choice. However, the sample is from a single industry; it will be fruitful to further verify these findings in other industries such as the manufacturing sector. Moreover, the definition of FUB is confined to explicit forms such as participation or collusion but there is no way to measure the implicit forms of FUB.

First, the governance of FUB should not only focus on the firms themselves, but also take into account the industrial market structure. Second, proper use of governance measures for FUB can increase firms’ benefits from “compliance with the law”, enticing firms to decrease FUB. The third, firms with weak market positions, facing fierce competition, should not be involved in FUB for short-term benefit; indeed, a low-cost strategy can be adopted as the dominant competitive strategy. While, in cases of highly concentrated market structure, firms should strive to avoid involvement in FUB through collusion with other rivals.

As it is a very common phenomenon that firms in competitive relationships may adopt FUB toward third parties or consumers, this trend has become a hot topic in the economic and social development in China. The study’s conclusions reveal that a more proactive and ambitious ethical decision is desirable for all kinds of firms; moreover, firms should make a rational choice between “short-term interest” and “long-term survival”. When firms identify the compliance of business ethics as an opportunity to differentiate themselves and perceive the benefits of decreasing FUB as outweighing the costs, the level of FUB will be inhibited, and social welfare will increase.

The primary contribution of this research resides in identifying product market competition as a previously unexplored predictor of FUB, thus revealing the dark side of product market competition. In addition, nonlinear relationships between product market competition and FUB indicate that situations of competition exert an important influence on FUB both at the firm and industry level. This paper’s conclusion provides a more meticulous theoretical explanation for FUB. This research demonstrates that the traditional ethical framework is not sufficient to explain FUB in a horizontal competitive context. Indeed, resource constraints and competitive pressures should also be considered.

The purpose of this study is to design carbon electrode materials for high performance electric double-layer capacitors (EDLCs) with pores that are large enough and have suitable pore size distribution for the electrolyte to access completely to improve EDLCs’ electrochemical performance.

This study develop an improved traditional KOH activation method, and a series of micro-meso hierarchical porous carbons have been successfully prepared from phenol formaldehyde resin by combining polyethylene glycol (PEG) and conventional KOH activation.

As evidenced by N₂ adsorption/desorption tests, the obtained samples present Types IV and I-IV hybrid shape isotherms compared with KOH-activated resin (typical of Type I). The sample AC2-7-1, which the addition quantity of PEG is 25 per cent PF (weight ration) activated at 700? For 1 h is considered as the optimum preparation condition. It exhibits the highest specific capacitance value of 240 F/g in 30 wt% KOH aqueous electrolytes because of its higher specific surface area (2085 m2/g), greater pore volume (1.08 cm3/g) and the maximum mesoporosity (43 per cent). In addition, the capacity decay of this material is only 3.1 per cent after 1000 cycles.

The materials that are rich in micropores and mesopores show great potential in EDLC capacitors, particularly for applications where high power output and good high-frequency capacitive performances are required.

The study aims to carry out the production of a bulk heterojunction organic solar cell in a laboratory scale using a blend of poly (3-hexylthiopene) (P3HT) and [6, 6]-phenyl (C61) butyric acid methyl ether (PCBM).

Four inverted geometry organic solar cells were prepared based on 1:1 ratio of P3HT to PCBM and subjected to post annealing at different temperatures of 32, 120, 130 and 140°C. Solar cells were fabricated with structure glass/ITO/P3HT:PCBM/PEDOT:PSS/Au and characterized using Keithley 2400 series sourcemeter and a multimeter interfaced to a computer system with a LabVIEW software, which showed both dark and illumination current–voltage characteristic curves. Four reference cells were also fabricated with structure soda lime glass/P3HT:PCBM and annealed at different temperatures of 32, 120, 130 and 140°C.

The third organic solar cell prepared, Sample CITO, had the best performance with power conversion efficiency (PCE) of 2.0281 per cent, fill factor (FF) of 0.392, short circuit current of −0.0133 A and open circuit voltage of 0.389 V. Annealing of active layer was found to improve cell morphology, FF and PCE. Annealing of the active layer at 140°C resulted in a decrease of the PCE to 2.01 per cent.

These findings are in good agreement with previous investigation in literature which reported that best annealing temperature for a 1:1 ratio blend of active material is 130°C. Ultraviolet–visible spectra on reference cells showed that sample CITO had wider absorption spectra with peak absorbance at a wavelength of 508 nm.
