Design and development of a digital platform for seasonal jobs: Improving the hiring process
Nuno Martins,Sérgio Dominique-Ferreira,Cátia Lopes 한국마케팅과학회 2022 마케팅과학연구 Vol.32 No.3
The seasonality of employment in tourism consists of challenges of hiring. The primary goal of this study was to develop a digital recruitment platform for the tourism industry. A two-step multidimensional approach was applied to the challenge. The first step was based on benchmarking and interviews with key stakeholders. The second step was based on visual identity factors, prototyping, and usability tests. Authors found that it was possible to develop a simple and intuitive digital platform that positively adjusted the dynamic hiring process for seasonal jobs. Improvements to the platform should include new metrics, such as evaluation of candidates who used this platform previously, based on different elements, such as emotional intelligence. In this way, profile matching could be optimized, and the platform tool would become more robust and useful. This study’s medium- and high-fidelity models of a digital platform to be utilized in human resources tasks are the new additions to toolkits that may streamline HR functions.

Contemporary architecture has an increasing importance in tourism. The marketing implications of digital or mobile content in this niche tourism space has not been previously studied. With this project we aim to build a mobile app to cater to this market and show that it can positively impact tourism in Portugal. A two-step multidimensional approach was applied to achieve this goal. The first step was based on benchmarking, as well as interviews with two architects. The second step was based on visual identity factors, prototyping, and usability tests. We found that it was possible to develop an intuitive app that positively adjusted to the needs and preferences of future users. Improvements to the platform should include new metrics, blog links, and augmented reality.

Objective: Lithium is a drug of choice in the treatment of bipolar disorder and refractory depressive disorders. However, previous research suggests lithium has a negative cognitive impact in recovery from electroconvulsive therapy (ECT) and a higher risk of delirium, so patients are often required to stop taking lithium before ECT, despite risk of relapse. We studied the cognitive impact of serum lithium levels in patients undergoing ECT. Methods: This was an observational prospective study. Serum lithium levels, thyroid and biochemical parameters were measured prior to each ECT session. Time elapsed from the anesthetic induction to the electrical stimulus and then to the patients’ reorientation was recorded, as well as the motor seizure duration and electroencephalogram (EEG) seizure duration. A statistical analysis using a linear mixed model was run while adjusting for confounding factors. Results: Ten participants underwent a total of 86 ECT sessions (41% right unilateral ultrabrief pulse, and 59% bilateral brief pulse). A negative interaction between lithium levels and reorientation time was found among those doing bilateral brief pulse ECT. No association was observed in patients doing unilateral ultrabrief pulse ECT. No significant relationship was observed between lithium and both motor and EEG-assessed seizure duration. Conclusion: This study suggests that low to moderate serum lithium levels (< 0.7 mmol/L) might have no harmful cognitive effects in patients under right unilateral ultrabrief pulse and bilateral brief pulse ECT.
Self-sustained n-Type Memory Transistor Devices Based on Natural Cellulose Paper Fibers
Martins, Rodrigo,Pereira, Luis,Barquinha, Pedro,Correia, Nuno,Goncalves, Goncalo,Ferreira, Isabel,Dias, Carlos,Correia, N.,Dionisio, M.,Silva, M.,Fortunato, Elvira The Korean Infomation Display Society 2009 Journal of information display Vol.10 No.4
Reported herein is the architecture for a nonvolatile n-type memory paper field-effect transistor. The device was built via the hybrid integration of natural cellulose fibers (pine and eucalyptus fibers embedded in resin with ionic additives), which act simultaneously as substrate and gate dielectric, using passive and active semiconductors, respectively, as well as amorphous indium zinc and gallium indium zinc oxides for the gate electrode and channel layer, respectively. This was complemented by the use of continuous patterned metal layers as source/drain electrodes.

Study Design: This study is a post hoc analysis of a multicenter prospective randomized controlled trial which compared artificial disc replacement and anterior cervical discectomy and fusion. Purpose: Useful radiographic parameters for assessing cervical alignment include the Cobb angles, T1 slope (T1S), occipitocervical inclination (OCI), K-line tilt (KLT), and cervical sagittal vertical axis (cSVA). This study aimed to determine measurement accuracy and reliability for these parameters. Overview of Literature: Various authors have assessed repeatability by comparing different methods of measurement, but knowledge of measurement error and minimal detectable change is scarce. Methods: We evaluated 758 lateral cervical radiographs. One medical student and one spine surgeon (i.e., measured ×2 within 4 weeks) independently measured the parameters obtaining 5,850 values. Standard error of measurement (SEm) and minimum detectable change (MDC) were calculated for each parameter. The accuracy and reliability of the Cobb angle measurements were calculated for the different types of angles: cervical lordosis, prosthesis angle, segmental angle with two bone surfaces (SABB), and segmental angle with one bone and one metal surface. Reliability was determined with intraclass correlation coefficient (ICC). Results: SEm was 1.8° and MDC was 5.0° for the Cobb angle, with an intraobserver/interobserver ICC of 0.958/0.886. All the different subtypes of Cobb angles had an ICC higher than 0.950, except SABB (intraobserver/interobserver ICC of 0.922/0.716). The most accurate and reliable measurement was for KLT. Conclusions: This study provides normative data on SEm and MDC for Cobb angles, T1S, KLT, OCI, and cSVA in cervical lateral radiographs. Reliability was excellent for all parameters except SABB (e.g., good).
