As one of the most cutting-edge technologies in the digital age, facial enhancement technology (FET) has greatly enhanced consumer online shopping experience and brought new e-commerce opportunities for cosmetics retailers. The purpose of this paper is to extend the unified theory of acceptance and use of technology (UTAUT) model in the context of FET. In addition to the concepts from the original model, the new FET-UTAUT model features (low) body esteem, social media addiction and FET adoption.

A purposive sampling of FET users in China via an online questionnaire yields 473 respondents. To analyze the data, this research uses the structural equation modeling method via statistical package for the social sciences and analysis of a moment structures software. A two-step approach, exploratory factor analysis and confirmatory factor analysis, was used to test the hypotheses and generate the findings.

Performance expectancy, effort expectancy, social influence, facilitating conditions and (low) body esteem have positive relationships with FET adoption. FET adoption has a positive relationship with online purchase intention of branded color cosmetics, and the empirical evidence for the moderating role of social media addiction in the relationship between FET adoption and online purchase intention is inconclusive.

This research extends the traditional UTAUT model by proposing a novel FET-UTAUT model that incorporates additional key concepts such as body esteem, FET adoption and social media addiction. Managerial implications of this research are provided for FET designers and branded color cosmetic retailers.

The Further Education and Training (FET) sector is being positioned as a centrepiece of the government's post-pandemic recovery. However, issues of capacity and staff churn are threatening the potential success of this strategy. Unfortunately, there has been almost no strategic analysis of teacher churn in the English FET system or of the derivative issues of recruitment and retention, both of which jeopardise the sector's capacity to deliver high-quality teaching and improve workforce skills. This paper examines these issues for policymakers and sector leaders and makes suggestions on how these can be redressed. A call for a more joined-up FET sector is presented.

This is a follow-up paper to a report published by the Education and Training Foundation in 2022 on teacher recruitment in the English FET sector. This paper pulls together all of the most recent research on the English FET sector on teacher recruitment and retention and frames these against the DfE's Skills for Jobs policy commitments. It also analyses a number of proposed solutions, reflecting on their merits and potential consequences.

An updated profile of FET institutions within the college, private training and adult subsectors is offered, showing how the FET sector in England has been in steady decline, which is juxtaposed against the rhetoric of industrial productivity and economic renewal. Four variables, namely funding, institutional numbers, staffing and learner numbers are examined to explore this disparity. A more in-depth analysis of recruitment and retention research follows, showing that pay, job insecurity and status are the factors influencing the decision to start an FET career. Strategies for remedying the “crisis” are assessed, including the role of national campaigns and professional bodies.

The first point for any research programme is to draw together the research data and themes that have been previously discussed in order to build a platform for future investigation, which is what this paper does. There are clear steers on where future research might be located: staff well-being, professional status, recruitment methods and what is meant by an FET career. These are factors that affect the desirability of FET work and the sector's ability to recruit high-quality candidates. The consequences of not doing this research is the likely continuation of the status quo, which is unsustainable for the FET sector and potentially catastrophic to UK productivity.

Policymakers and sector leaders are presented with analysis and advice on the impact of teacher shortages and the factors that contribute to this. The evidence to support these factors is explored and solutions discussed in light of this evidence. A research agenda is suggested including an appeal for professional organisations and FET stakeholders to work together to solve the recruitment and retention crisis. The power of research to enlighten and inform is one of several conclusions proposed.

Addressing the factors that corrode staff professionalism and increase teacher attrition is an essential component of a wider discourse to improve the desirability of an FET career. Issues of status and esteem are interwoven in this analysis, as are the implications of not recruiting talented teachers and assessors. This includes staff well-being – a rare topic in FET journal papers – as well as organisational culture and importance of the FET mission, which is considered to be embedded in an ethic of public service. This mission is linked via the Augur Report to the sector's transformational properties to raise social mobility.

There is no precedent for this paper. It is the first article that has provided a comprehensive examination of teacher recruitment and retention issues affecting the whole FET sector in England. Whilst its comparative analysis builds on the Education and Training Foundation (2022) earlier report, it uniquely draws on other contemporary research that triangulates and discusses these findings, including setting out a new agenda for change and future research. In doing so, new issues are introduced for discussion including professional status and staff well-being.

The purpose of this paper is to present a DNA hybridization detection sensor. An inexpensive fabrication procedure was used so that the sensors can be disposed economically after the measurement is completed.

Field effect transistor (FET) devices are used in the proposed structure. The FET device acts as a charge detection element and produces an amplified output current based on surface charge variations. As amplification is performed directly at the sensor frontend, noise sources have less effect on the detected signal, and thus, acceptably low DNA concentrations can be detected with simple external electronics. ZnO nano layers are used as the FET active semiconductor channel. Furthermore, a photobiasing approach is used to adjust the operating point of the proposed FET without the need for an additional gate terminal.

The proposed sensor is evaluated by applying matched and unmatched target DNA fragments on the fabricated sensors with capture probes assembled either directly on the ZnO surface or on a nano-platinum linker layer. It is observed that the presented approach can successfully detect DNA hybridization at the nano mole range with no need for complex laboratory measurement devices.

The presented photobiasing approach is effective in the adjustment of the sensor sensitivity and decreases the fabrication complexity of the achieved sensor compared with previous works.

This paper aims to examine the prospect for international investment disputes in the aftermath of the COVID-19 pandemic due to measures implemented by the Australian government to tackle the pandemic.

Doctrinal research. Contains qualitative analysis.

This paper finds that claims based on the protections in the International Investment Agreements (IIAs) signed by Australia are unlikely to succeed and that Australia’s COVID-19 measures can be justified as necessary measures under the general and security exception clauses included in more recent IIAs and under customary international law.

In the context of the COVID-19 pandemic, scholars have written papers apprehending possible claims by international investors against emergency measures adopted by host countries to face the pandemic which might also have damaged the interest of the foreign investors. The existing literature is too vague and general. To the best of the authors’ knowledge, this is the first paper that draws some specific conclusions in this regard applicable to the COVID-19 regulatory measures taken by Australia. While the existing literature projects the possibility of such investor claims, this paper argues that at least no such claim would succeed against the COVID-19 measures taken by Australia.

Smart biosensors that can perform sensitive and selective monitoring of target analytes are tremendously valuable for trinitrotoluene (TNT) explosive detection. In this research, the pre-developed sensor was integrated with biological receptors in which they enhanced the sensitivity of the sensor. This is due to conjugated polydiacetylene onto a peptide-based molecular recognition element (Trp-His-Trp) for TNT molecules in graphene field-effect transistors (GR-FETs) as biosensor that is capable of responding to the presence of a TNT target with a colorimetric response. The authors confirmed the efficacy of the receptor while being attached to polydiacetylene (PDA) by observing the binding ability between the Trp-His-Trp and TNT to alter the electronic band structure of the PDA conjugated backbones. The purpose of this paper is to demonstrate a modular system capable of transducing small-molecule TNT binding into a detectable signal. The details of the real-time and selective TNT biosensor have been reported.

Following an introduction, this paper describes the way of fabrication GR-FETs with conventional photolithography techniques and the other processes, which is functionalized by the TNT peptide receptors. The authors first determined the essential TNT recognition elements from UV-visible spectrophotometry spectroscopy for PDA sensor unit fabrication. In particular, the blue percentage and the chromic response were used to characterize the polymerization parameter of the conjugated p backbone. A continuous-flow trace vapor source of nitroaromatics (two, four, six-TNT) was designed and evaluated in terms of temperature dependence. The TNT concentration was measured by liquid/gas extraction in acetonitrile using bubbling sequence. The sensor test is performed using a four-point probe and semiconductor analyzer. Finally, brief conclusions are drawn.

Because of their unique optical and stimuli-response properties, the polydiacetylene and peptide-based platforms have been explored as an alternative to complex mechanical and electrical sensing systems. Therefore, the authors have used GR-FETs with biological receptor-PDAs as a biosensor for achieving high sensitivity and selectivity that can detect explosive substances such as TNT. The transport property changed compared to that of the field-effect transistors made by intrinsic graphene, that is, the Dirac point position moved from positive Vg to negative Vg, indicating the transition of graphene from p-type to n-type after annealing in TNT, and when the device was tested from RT, the response of the device was found to increase linearly with increasing concentrations. Average shifting rate of the Dirac peak was obtained as 0.1-0.3 V/ppm. The resulting sensors exhibited at the limit ppm sensitivity toward TNT in real-time, with excellent selectivity over various similar aromatic compounds. The biological receptor coating may be useful for the development of sensitive and selective micro and nanoelectronic sensor devices for various other target analytes.

The detection of illegally transported explosives has become important as the global rise in terrorism subsequent to the events of September 11, 2001, and is at the forefront of current analytical problems. It is essential that a detection method has the selectivity to distinguish among compounds in a mixture of explosives. So, the authors are reporting a potential solution with the designing and manufacturing of electrochemical biosensor using polydiacetylene conjugated with peptide receptors coated on GR-FETs with the colorimetric response for real-time detection of TNT explosives specifically.

Mentoring processes and relationships can prove crucial to teachers in the initial phases of the teacher education continuum. Limited research exists regarding mentoring in further education and training (FET) in Ireland. This paper attempts to address this gap, illuminating and unpacking the “mentoring stories” of five teachers in FET.

The overall project adopted a narrative approach. Data were collected via in-depth interviews, part of which clearly focussed on participants' lived experience of mentoring. Thematic analysis revealed four overarching themes.

The themes reveal a spectrum of practices and perspectives on the role of mentors. There are ample instances of collegiality, mutual respect and an appreciation of the professional life stage of the mentee. However, evidently a lack of understanding of who mentors are and what they do persists, leading to some informal approaches and opening up the potential for misinterpretation and misalignment.

This paper sheds light on an area of FET practice that has been relatively unseen before now. It gives voice to those who have experienced mentoring in the Irish FET sector that, to a degree, has seen structural and attitudinal transformations in recent times.

The purpose of this paper is to present computer‐aided simultaneous signal and noise modeling and analysis for mm‐wave field‐effect transistors (FETs) based on scattering parameters approach.

A mm‐wave FET is modeled as three active‐coupled transmission lines, and the developed wave approach is applied to this model to calculate both signal and noise performances of the device.

The measurements show a good match with the calculated data from the point of view of both signal and noise performances of the device.

This CAD‐oriented analysis and modeling can be easily applied to the mm‐wave simulators to improve the simultaneous signal and noise optimization, modeling and analysis of mm‐wave devices, especially for traveling wave transistors in which the distributed model seems to be more exact than the usual lumped models. Also the proposed routine compared to the admittance approach is conceptually more compatible with scattering representations of active and passive circuits. The developed algorithm has been applied successfully to mm‐wave MESFETs and HEMTs.

Workplace learning (WL) is a key part of vocational education and training (VET) because it allows students to develop their skills in a work environment, and provides important information about how well VET studies prepare skilled workers. Therefore, the purpose of this paper is to develop and validate an instrument to evaluate WL efficacy in VET.

The research presented in this paper was based on a quantitative design, after having identified factors that influence training efficacy. The factors to evaluate transfer in WL (FET-WL) questionnaire was formed of 57 items (five-point Likert scale) and applied to a stratified probabilistic sample of 1,026 VET students in the Barcelona area (Spain).

After conducting an exploratory factor analysis, the model explained 48.42 per cent of the variance and six factors merged: coherence of the training of the school with the WL, school tutor’s sole, host company tutor’s role, the possibilities of developing the WL, integration into the company and student’s motivation.

Results show that the FET-WL may be a useful tool for the various agents involved in WL since it may improve the organization and management of VET and thereby increase its efficacy.

It has been observed that the students attending the bachelor’s degree programmes offered by the Faculty of Engineering Technology (FET) at the Open University of Sri Lanka (OUSL) take extraordinarily longer period to complete their degrees. The purpose of this paper is to identify the institutional barrier, student-related personal barrier and psychological barrier behind the prolonged duration of completion of the said degrees.

A well-developed questionnaire was administered among a selected sample of graduates who were awarded the Bachelor of Technology (Engineering) and Bachelor of Industrial Studies degrees within the past ten years.

Results indicate that institutional barriers such as poor academic counselling and guidance; laboratory sessions being inappropriate/not sufficient to understand the course material; inadequate facilities, such as library resources, and lack of laboratory facilities at the regional centres have contributed immensely to the lengthy duration taken to complete the degrees. Personal factors such as work-related challenges, travelling time and cost of commuting to the main centre located in Colombo and inability to spend the required time expected of the programme have played major roles in the prolonged completion. Results indicate that the cost of tuition is not a major barrier for on-time completion. Psychological barriers such as possessing a limited repertoire of study strategies, lack of understanding of open and distance learning (ODL) methods and deficiency of continuous motivation had a tremendous impact on the delayed graduation. A high satisfaction rate was observed regarding the ODL tools that were used within the programmes and the formative and summative evaluation criteria. Approximately 75 per cent of the sample approved of the five remedies suggested.

Findings of this study provide insight for shortening the duration of the bachelor’s degree programmes offered by the FET at the OUSL.
