To better respond to user needs for personalized information services in the context of academic libraries, this study aims at developing a prototype to provide mobile curation services by using the concept of content curation.

This study used a mobile application software development process, which consisted of five phases: user and organizational requirements, architecture design, navigation design, page design and implementation and usability testing. Usability testing was conducted with a total of 20 college students by online surveys at a university.

Meta-analysis identified key user needs: diversification of services, more personalized services, active communication with librarians, quality improvement of information and interface improvement. User and organizational requirements derived four main service modules – namely, Curation Services, Live Chat, My Page and My Log. Usability testing regarding ease of use, perceived usefulness and satisfaction indicated that participants were satisfied with the prototype.

The study extends the discussion of quality academic library services by introducing the concept of content curation that uses the advantages of mobile technologies to overcome existing limitations in library services insufficient for meeting individual user needs.

Although many studies have discussed mobile library services, few studies have focused on developing a system for such services. The model developed in the study fills the research gap. Above all, the key modules specified by the prototype – Curation Services, Live Chat, My Page and My Log services – are expected to improve existing research and learning support services currently offered by academic libraries.

Based on the transactional theory of stress and coping, this study aims to understand the daily impact of coronavirus disease 2019 (COVID-19) on employee goal progress. In particular, the authors explore how COVID-19 induces anxiety related to task setbacks that consequently influences one's goal progress.

A daily diary study was conducted with a total of 558 observations from 60 participants. The data were analyzed using multilevel path analysis with random slopes.

The perceived risk of COVID-19 infection was positively associated with COVID-19 task setback anxiety, which in turn improved end-of-day goal progress. Lower employee conscientiousness strengthened the relationship between perceived risk of COVID-19 infection and COVID-19 task setback anxiety, and lower supervisor bottom-line mentality strengthened the relationship between COVID-19 task setback anxiety and end-of-day goal progress.

Although COVID-19 task setback anxiety results in higher end-of-day goal progress, the authors recommend caution as the cost of coping exists. Thus, supervisors should focus on supporting the employees rather than having a bottom-line mentality.

This study advances stress and coping literature by examining how employees appraise and cope with COVID-19 in work context. The authors demonstrate that a perceived risk of COVID-19 induces task setbacks related to anticipatory anxiety, which in turn influences employee outcomes. In addition, the authors identify employee conscientiousness and supervisor bottom-line mentality as a boundary condition of this process.

Because of importance of technological learning for less developed countries, the notion has received increasing attention of scholars. The purpose of this paper is to investigate technological learning systematically by assessing the effect of technology transfer actors on technological learning in less developed countries context.

The paper presents assessment model by adopting technological learning concept based on technology absorption and incremental innovation at firm level and identifying key roles of technology transfer actors (State – Scientific and technological infrastructure – Industry) that affect technological learning. The paper follows survey as research methodology. Thus, a questionnaire was addressed to 33 Syrian textile factories to examine the assessment model. Simple linear, multiple linear and ordinal regression analyses are preformed to examine relationships of model components.

The regression models show notable ability of technology transfer actors to explain technological behavior of firms to accumulate operative capability and consequently to generate passive incremental innovation. The findings indicate passive technical change system of Syrian textile industry. Therefore, goal-oriented evaluation of actual technology policy is preliminary step for achieving improvements, as well as activating scientific and technological infrastructure role by enabling strong relationships with industry and supporting interactions of domestic firms of textile industry and with foreign players.

The paper enriches technological learning literature by proposing systematic approach that sets the nature of technical change process of less developed countries in core of analysis. Moreover, it provides a guide for technological learning practices at firm level and for policymakers based on assessing actual status of Syrian textile industry.

This study was conducted to examine the effect of co-branding, a brand partnership tactic involving two or more brands, on consumer behavior within the sport industry. As such, the primary aim was to examine differences regarding consumers' perceptions of self-image congruence and perceived product quality when considering solo-branding and co-branding conditions. Further, under the co-branding condition, relationships among consumers' self-image congruence, perceived product quality, image fit, product evaluation and purchase intention were investigated.

A scenario-based quasi-experiment consisting of hypothetical co-branding initiatives between existing brands was conducted.

Results from a repeated multivariate analysis of variance (MANOVA) indicated that consumers' symbolic and functional perceptions of co-branding as well as evaluations were statistically higher than in the solo-branding condition. Additionally, structural equation modeling indicated positive relationships between consumers' symbolic and functional perceptions, image fit, evaluation and behavior intention.

This study is one of the first papers to investigate the impact of co-branding on consumers within the sport industry and provides evidence of the positive impact of co-branding strategies on consumer behavior within the sport industry.

To solve the shortcomings of existed search and rescue drones, search and rescue the trapped people trapped in earthquake ruins, underwater and avalanches quickly and accurately, this paper aims to propose a four-axis eight-rotor rescue unmanned aerial vehicle (UAV) which can carry a radar life detector. As the design of propeller is the key to the design of UAV, this paper mainly designs the propeller of the UAV at the present stage.

Based on the actual working conditions of UAVs, this paper preliminarily estimated the load of UAVs and the diameters of propellers and designed the main parameters of propellers according to the leaf element theory and momentum theory. Based on the low Reynolds number airfoil, this paper selected the airfoil with high lift drag ratio from the commonly used low Reynolds number airfoils. The chord length and twist angle of propeller blades were calculated according to the Wilson method and the maximum wind energy utilization coefficient and were optimized by the Asymptotic exponential function. The aerodynamic characteristics of the designed single propeller and coaxial propeller under different installation pitch angles and different installation distances were analyzed.

The results showed that the design of coaxial twin propellers can increase the load capacity by about 1.5 times without increasing the propeller diameter. When the installation distance between the two propellers was 8 cm and the tilt angle was 15° counterclockwise, the aerodynamic characteristics of the coaxial propeller were optimal.

The novelty of this work came from the conceptual design of the new rescue UAV and its numerical optimization using the Wilson method combined with the maximum wind energy utilization factor and the exponential function. The aerodynamic characteristics of the common shaft propeller were analyzed under different mounting angles and different mounting distances.
