Solution-processed hybrid perovskite photodetectors with high detectivity

Fast-response and high-sensitivity deep-ultraviolet (DUV) photodetectors with detection wavelength shorter than 320 nm are in high demand due to their potential applications in diverse fields. However, the fabrication processes of DUV detectors based on traditional semiconductor thin films are complicated and costly. Here we report a high-performance DUV photodetector based on graphene quantum dots (GQDs) fabricated via a facile solution process. The devices are capable of detecting DUV light with wavelength as short as 254 nm. With the aid of an asymmetric electrode structure, the device performance could be significantly improved. An on/off ratio of ∼6000 under 254 nm illumination at a relatively weak light intensity of 42 μW cm–2 is achieved. The devices also exhibit excellent stability and reproducibility with a fast response speed. Given the solution-processing capability of the devices and extraordinary properties of GQDs, the use of GQDs will open up unique opportunities for future high-performance...

Entrepreneurial intention is a rapidly evolving field of research. A growing number of studies use entrepreneurial intention as a powerful theoretical framework. However, a substantial part of this research lacks systematization and categorization, and there seems to be a tendency to start anew with every study. Therefore, there is a need to take stock of current knowledge in this field. In this sense, this paper carries out a review of the literature on entrepreneurial intentions. A total of 409 papers addressing entrepreneurial intention, published between 2004 and 2013 (inclusive), have been analyzed. The purpose and contribution of this paper is to offer a clearer picture of the sub-fields in entrepreneurial intention research, by concentrating on two aspects. Firstly, it reviews recent research by means of a citation analysis to categorize the main areas of specialization currently attracting the attention of the academic community. Secondly, a thematic analysis is carried out to identify the specific themes being researched within each category. Despite the large number of publications and their diversity, the present study identifies five main research areas, plus an additional sixth category for a number of new research papers that cannot be easily classified into the five areas. Within those categories, up to twenty-five different themes are recognized. A number of research gaps are singled out within each of these areas of specialization, in order to induce new ways and perspectives in the entrepreneurial intention field of research that may be fruitful in filling these gaps.

A systematic literature review on entrepreneurial intentions: citation, thematic analyses, and research agenda

Recent shifts in education and labour market policy have resulted in universities being placed under increasing pressure to produce employable graduates. However, contention exists regarding exactly what constitutes employability and which graduate attributes are required to foster employability in tertiary students. This paper argues that in the context of a rapidly changing information- and knowledge-intensive economy, employability involves far more than possession of the generic skills listed by graduate employers as attractive. Rather, for optimal economic and social outcomes, graduates must be able to proactively navigate the world of work and self-manage the career building process. A model of desirable graduate attributes that acknowledges the importance of self-management and career building skills to lifelong career management and enhanced employability is presented. Some important considerations for the implementation of effective university career management programs are then outlined.

The graduate attributes we've overlooked : enhancing graduate employability through career management skills

This study is motivated by highly concentrated ownership, the relatively large government stake in listed firms in the GCC (Gulf Cooperative Council) region, and the rapid stock market development and developing investor protection environment. The results point to heterogeneity in governance quality across exchanges. For the first time, we find that the positive relationship between governance quality and firm performance is maintained and is stronger at low levels of concentrated ownership. More interestingly, we find that the relationship between governance and firm performance is an increasing function of dispersed ownership and that the value addition of good governance is not necessarily maintained at high levels of ownership concentration. Furthermore, such a relationship reaches its highest level when the government or local corporations are the firm’s major shareholders.

Corporate Governance Practices, Ownership Structure, and Corporate Performance in the GCC Countries

This paper examines the effect of corporate governance denoted by board size, duality, agency cost etc. on theperformance of selected 24 GCC banks based on the criteria of total assets for the financial year 2012-13.Tobin’s Q and Return on Total Assets (ROTA) are adopted as a measurement of accounting and financialperformance respectively.The results indicate that smaller boards are more capable for monitoring the management closely in GCCbanking sector. Dual role of Chief Executive Officer (CEO) are likely to improve the GCC bank performance.The presence of block holders in ownership structure of GCC banks tends to have a positive effect on theperformance of banking sector. Overall, the study concludes that the corporate governance poses a significantinfluence on the financial and accounting performance of GCC banking sector.

Low-frequency noise properties of 100 nm-thick Langmuir–Blodgett (LB) films of stearic acid in a metal–insulator–semiconductor (MIS) structure have been studied as a function of frequency and leakage current. The excess noise is found to be consistently 1/f-like within a range of frequencies between 1 Hz to 1 kHz when leakage current is varied from 10−8 A to 10−4 A. The sources of noises are identified; the trap density is estimated to be 3.6 × 1018 m−2 eV−1.

Employers now require employees who mastered the technical and employability skills. Unfortunately employability skills acquired by does not meet the criteria education institution graduates by employers. This study aims to evaluate the level of employability skills on engineering students at higher education institutions from the perspective of employers. The descriptive study used quantitative approach involve a total of 171 respondents which is the engineering employers who were provided placement for industrial training to students of technical institutions. The instrument used in this study were adapted from the instruments of Modul Kemahiran Insaniah Kementerian Pengajian Tinggi Malaysia, Secretary’s Commission on Achieving Necessary Skill (SCANS) Amerika, Malaysian Qualification Framework (MQF), MyGSI and IKGPP and severel models from previous studies. The variables of this study are communication skills, spiritual skills, teamwork, leadership, lifelong learning and information management, critical thinking and problem solving, entrepreneurship, ethics and morality, technology skills, and social skills. Data collected were analyzed using descriptive and inferential analysis statistics. The results showed that the level of employability skills among engineering students from the employer's perspective is moderately high. The results also showed that there are no significant differences between student’s employability skills that are assessed against the nature of the industry, the position and the employer experience, and the location of the industry.

The purpose of the present study is to test how do the four important psychological
antecedents, namely need for achievement (nAch), propensity to risk (PtR), self-confidence
(SeC), internal locus of control (IlC) are mediated by the entrepreneurial selfefficacy
(ESE) to predict the entrepreneurial intention (EI) in a traditionally oil-based
Saudi economy striving for economic diversification. Hypotheses are tested by applying
the partial least square (PLS) structural equation modeling (SEM) to a sample of
282 undergraduate business students (male and female) collected from a public university
of Kingdom of Saudi Arabia (KSA). The results suggest that psychological variables
and self-efficacy play a fundamental role in enhancing entrepreneurial intention (EI)
of Saudi students. Personality-related variables have direct influence over EI in other
context, but in Saudi context, psychological variables are necessary but not sufficient to
develop entrepreneurial intention unless combined with self-efficacy. Self-efficacy has
a strong mediating effect between psychological variables and entrepreneurial intentions
in Saudi context.
