The purpose of this paper is to investigate: first, the effects of a user’s grandiosity on the loneliness of another user on Facebook who detected it in terms of his/her well-being status; second, the mediational role of envy between grandiosity and loneliness; and, third, whether different effects are given on narcissism, envy, and loneliness depending on social or para-social relationships on Facebook.

This study’s focus is to investigate how observing others’ grandiose behaviors impact on individuals’ feeling of loneliness. The authors propose that this relationship is mediated by the feeling of envy. The authors further postulate that social relationships that participants may have with other Facebook users would play a key role in feeling different types of envy (i.e. malicious vs benign). Therefore, the current study employed a 2 (levels of grandiosity: high vs low) × 2 (social relationship: para-social vs social) between-subjects design.

The authors found that one’s grandiosity as reflected on Facebook significantly affects other users’ loneliness through malicious envy. However, no moderated mediation via envy (either benign or malicious) was found within the social relationship group.

Social comparison generated by the use of Facebook was found to have an effect on the user’s loneliness through the mediation of envy. In particular, the possibility that such effects could be triggered in para-social relationships was identified.

The secondary phase decreased the corrosion resistance because of the segregation of Cr and Mo. Therefore, this paper aims to study the precipitation condition and the effect of secondary phase with volume fraction on corrosion behavior.

Secondary phase precipitated approximately from 375°C to 975°C because of saturated Cr and Mo at grain boundary by growth of austenite. Therefore, heat treatment from 800°C to 1,300°C was applied to start the precipitation of the secondary phase.

The secondary phase is precipitated at 1,020°C because of segregation by heterogeneous austenite. The growth of austenite at 1,000°C needs the time to saturate the Cr and Mo at grain boundary. When the volume fraction of austenite is 56 per cent (14 min at 1,000°C), the secondary phase is precipitated with grain boundary of austenite. The secondary phase increased the current density (corrosion rate) and decreased the passivation. That is checked to the critical pitting temperature (CPT) curves. The 1 per cent volume fraction of secondary phase decreased CPT to 60°C from 71°C.

The precipitation of secondary phase not wants anyone. Casted super-duplex stainless steel (SDSS) of big size precipitates the secondary phase. This study worked the precipitation condition and the suppression conditions of secondary phase.

Manufacturers need precipitation condition to make high-performance SDSS.

The corrosion resistance of SDSS is hard the optimization because SDSS is dual-phase stainless steel. The precipitation of the secondary phase must be controlled to optimize of the corrosion resistance of SDSS. Anyone not studied the precipitation condition of secondary phase and the effect of secondary phase with volume fraction on corrosion behavior of SDSS.

The purpose of this paper is to investigate the mediating role of innovative behavior on the relationships between organizational structure, such as centralization, formalization, integration, and organizational innovation performance.

The authors collected data from 140 functional managers of manufacturing organizations in the Republic of Korea. The authors used structural equation modeling procedure to evaluate the validity of proposed hypotheses.

The results suggest that innovative behavior mediates the links among centralization, formalization, and organizational innovation performance. However, the findings indicate that innovative behavior does not mediate the relationship between integration and organizational innovation performance.

This work is the first to examine the mediating role of innovative behavior on the associations among centralization, integration, and organizational innovation performance.

In this study, super duplex stainless steel (SDSS) was heat-treated. The purpose of this study is to assess the effect of the cooling rate after heat treatment on the pitting corrosion of SDSS.

The heat treatment from 1,000°C to 1,300°C was applied to SDSS to check the effect of the cooling rate.

The heat treatment temperature produced a different SDSS microstructure, and the cooling rate led to the growth of austenite. The casted SDSS indicated the presence of heterogeneous austenite, and the precipitation secondary phase under 1.6 per cent precipitated to bare metal. By applying heat treatment and cooling SDSS, its corrosion resistance changes because of the change in the chemical composition. The cooling rate at 5,600 J/s has the highest critical pitting temperature (CPT) at 1,100°C, and the cooling rate at 1.6 J/s has the highest CPT at 1,200°C. Low cooling rate (0.4 J/s) made the secondary phase at all temperature range.

The effect of secondary phase not consider because that is well known to decreasing corrosion resistance.

Solution annealing is taken into account to optimize the corrosion resistance. But that is not consider the cooling rate at each temperature. This study assessed the effect of the cooling rate at each temperature point.

Manufacturers need to know the effect of the cooling rate to optimize the corrosion resistance, and this study can be applied in the industrial scene.

SDSS is hard the optimization because SDSS is a dual-phase stainless steel. Corrosion resistance can be optimized by controlling heat treatment temperature and the cooling rate. Anyone not studied the effect of the cooling rate at each temperature. The effect of the cooling rate should be considered to optimize the corrosion resistance.

The purpose of this study is to examine the relationship between psychological contracts and subsequent internship outcomes, with a specific focus on employer obligations with regard to career development. The study also examines the potential moderating role of person–organization (P–O) fit.

Online surveys were administered to 196 college students both prior to and upon completing their summer internships. Moderated mediation analyses were performed following Hayes (2018).

The results show that employer fulfillment of career development is positively associated with organizational attractiveness, as mediated by intern skill acquisition. In addition, high levels of P-O fit ameliorated low developmental situations, with high P-O fit resulting in stronger attraction to the organization than low P-O fit.

The study underlines the importance of career development and the associated attainment of instrumental resources in the psychological contract process between organizations and interns. For the former, the provision of career development may increase interns' attraction to the organization. For interns, such opportunities can enhance skill acquisition, with differential effects for those with high and low P-O fit.

This study is the first to provide an empirical assessment of the instrumental outcomes of psychological contract fulfillment with regard to career development prior to formal organizational entry. It further sheds light on the interactive effect of skill acquisition and P-O fit in predicting individual perceptions of the organization.

A key concern in sports sponsorship decisions is knowing under what conditions sponsorship can effectively act as a brand building tool. The purpose of this study is to list attributes to use when examining congruency in the sponsorship of national football teams. The second aim was to test whether being a client of the sponsor brand and being involved with the sponsee moderates the relationship between image congruence and sponsorship response.

Data were collected on four sponsors of the Portuguese national team, just before the 20th Fédération Internationale de Football Association World Cup. Analyses were conducted on a representative national sample of fans. The research design encompassed a two-step approach. First, qualitative analysis identified the main attributes that fans associate with the national team. In the second quantitative phase, moderated regression analysis was used to test the proposed model.

This study confirmed sponsor–sponsee congruence in seven attributes (i.e. national symbol, strength, strong emotions, happiness, optimism, connection and positive feelings) enhances positive brand image and fans’ involvement with the national team moderates this relationship. Positive sponsorship outcomes tend to be higher for sponsors when fans are currently clients of the sponsor brand.

This study adds to previous research by using mixed methods to study sponsor–sponsee congruence regarding national teams and by testing whether fans being clients of sponsors and being involved with sponsees moderate sponsor–sponsee congruence.

AlSi10Mg alloy is commonly used in laser powder bed fusion due to its printability, relatively high thermal conductivity, low density and good mechanical properties. However, the thermal conductivity of as-built materials as a function of processing (energy density, laser power, laser scanning speed, support structure) and build orientation, are not well explored in the literature. This study aims to elucidate the relationship between processing, microstructure, and thermal conductivity.

The thermal conductivity of laser powder bed fusion (L-PBF) AlSi10Mg samples are investigated by the flash diffusivity and frequency domain thermoreflectance (FDTR) techniques. Thermal conductivities are linked to the microstructure of L-PBF AlSi10Mg, which changes with processing conditions. The through-plane exceeded the in-plane thermal conductivity for all energy densities. A co-located thermal conductivity map by frequency domain thermoreflectance (FDTR) and crystallographic grain orientation map by electron backscattered diffraction (EBSD) was used to investigate the effect of microstructure on thermal conductivity.

The highest through-plane thermal conductivity (136 ± 2 W/m-K) was achieved at 59 J/mm³ and exceeded the values reported previously. The in-plane thermal conductivity peaked at 117 ± 2 W/m-K at 50 J/mm³. The trend of thermal conductivity reducing with energy density at similar porosity was primarily due to the reduced grain size producing more Al-Si interfaces that pose thermal resistance. At these interfaces, thermal energy must convert from electrons in the aluminum to phonons in the silicon. The co-located thermal conductivity and crystallographic grain orientation maps confirmed that larger colonies of columnar grains have higher thermal conductivity compared to smaller columnar grains.

The thermal properties of AlSi10Mg are crucial to heat transfer applications including additively manufactured heatsinks, cold plates, vapor chambers, heat pipes, enclosures and heat exchangers. Additionally, thermal-based nondestructive testing methods require these properties for applications such as defect detection and simulation of L-PBF processes. Industrial standards for L-PBF processes and components can use the data for thermal applications.

To the best of the authors’ knowledge, this paper is the first to make coupled thermal conductivity maps that were matched to microstructure for L-PBF AlSi10Mg aluminum alloy. This was achieved by a unique in-house thermal conductivity mapping setup and relating the data to local SEM EBSD maps. This provides the first conclusive proof that larger grain sizes can achieve higher thermal conductivity for this processing method and material system. This study also shows that control of the solidification can result in higher thermal conductivity. It was also the first to find that the build substrate (with or without support) has a large effect on thermal conductivity.

How to model blind image deblurring that arises when a camera undergoes ego-motion while observing a static and close scene. In particular, this paper aims to detail how the blurry image can be restored under a sequence of the linear model of the point spread function (PSF) that are derived from the 6-degree of freedom (DOF) camera’s accurate path during the long exposure time.

There are two existing techniques, namely, an estimation of the PSF and a blind image deconvolution. Based on online and short-period inertial measurement unit (IMU) self-calibration, this motion path has discretized a sequence of the uniform speed of 3-DOF rectilinear motion, which unites with a 3-DOF rotational motion to form a discrete 6-DOF camera’s path. These PSFs are evaluated through the discrete path, then combine with a blurry image to restoration through deconvolution.

This paper describes to build a hardware attachment, which is composed of a consumer camera, an inexpensive IMU and a 3-DOF motion mechanism to the best of the knowledge, together with experimental results demonstrating its overall effectiveness.

First, the paper proposes that a high-precision 6-DOF motion platform periodically adjusts the speed of a three-axis rotational motion and a three-axis rectilinear motion in a short time to compensate the bias of the gyroscope and the accelerometer. Second, this paper establishes a model of 6-DOF motion and emphasizes on rotational motion, translational motion and scene depth motion. Third, this paper addresses a novel model of the discrete path that the motion during long exposure time is discretized at a uniform speed, then to estimate a sequence of PSFs.
