“Please Miss, Please!”: An observational study of young people’s social and emotional experiences post-transition to secondary school

The secondary school transition is considered a critical life event by practitioners and researchers alike, and the challenges presented by the pupils during this transition continues to be high-profile in educational, social and political contexts. This study focused on Year 7 pupils aged 11 to 12 years old in their first year of secondary school. Classroom observations of around 120 pupils using an open framework recording procedure offered real-time insights into the everyday lived experiences of these adolescents. The paper illustrates the skills and behaviours that children brought to their secondary school transition, and as such reveals how the transition should be perceived as both an event and a social and emotional learning process. The findings of this study highlight the challenges of flexibility and diversity within peer networks after the move to secondary school and the impact the transition can have on the pupils’ sense of self. The analysis is discussed in terms of implications for schools, practitioners and researchers with suggestions for further studies with this under-researched and vulnerable group.
A COMPARATIVE STUDY ON POWER CALCULATION METHODS FOR CONVEYOR BELTS IN MINING INDUSTRY

ABSTRACT This paper covers different methods to evaluate the power consumption of several conveyor belt systems (CBSs) used in the Turkish Mining Industry (TMI). Based on each CBS’s operational features, the power consumption (Pc, kW) was measured directly on motorised head-pulleys. The Pc was investigated through several conventional, statistical, and machine learning methods. This study shows that the DIN 22,101 could be the most convenient conventional method for the investigated CBSs. On the other hand, based on the nonlinear regression (NLR) and genetic expression programming (GEP) models, two new approaches were suggested for the design and optimisation of the Pc.
Cyber4Dev‐Q: Calibrating cyber awareness in the developing country context

Citizens of the hyper‐connected world face tremendous challenges in managing their personal online risks; that is to preserve their cyber safety, cyber security and cyber privacy. Governments allocate significant resources to raising awareness about these three areas among their citizens to equip them to manage their online risks. To ensure maximum efficacy, these endeavors must be able to gauge existing levels of awareness to ensure that awareness‐creation drives target population‐level awareness gaps. A number of excellent and rigorously developed questionnaires exist for this purpose. However, these may not be as accurate in revealing awareness gaps and issues in developing countries. Developing country citizens face a range of context‐specific challenges, distinct from those faced by developed country citizens. These are likely to impact their cyber awareness development and maintenance. A context‐sensitive cyber awareness measurement instrument designed for such a context has a better chance of revealing particular awareness aspects requiring attention. To meet this need, we developed and validated a cyber awareness questionnaire, the cyber awareness calibration instrument for developing countries (Cyber4Dev‐Q), for use in developing countries to measure the cyber awareness of their citizens in all three core cyber areas in a context‐sensitive fashion.
The negation of cualquier NP

Even though the interpretation of Free Choice Items such as any has been on debate for more than 50 years (Vendler, 1974, Dayal, 1998, Horn, 2000, etc.), it is relatively more recent in Spanish (Menéndez-Benito, 2005, Giannakidou and Quer, 2013, among others). Some have analyzed it as a universal quantifier, neither taking its free choiceness into account nor contexts which seem to be problematic for the universal account (see, for instance, Etxepare and Uribe-Etxebarria, 2011). In this article, we defend that cualquier is a universal indeterminate pronoun which involves freedom of choice (as in the original proposal by Vendler, 1974). We will take into account data (taken from https://www.corpusdelespanol.org/web-dial) which has not been properly considered. We will analyze the interaction of negation and cualquier in Rioplantese Spanish in the subject position of negative generic statements, in the object position in negative episodic statements, and in a non argumental position. We will combine an alternative semantics approach to the analysis of the FCI cualquier, inspired in Menéndez-Benito (2010) and Aloni (2019), with a syntactic approach to negation inspired in Etxepare and Uribe-Etxebarria (2011).
MODELACIÓN HIDROLÓGICA BAJO ESCENARIOS DE CAMBIO CLIMÁTICO PARA UN EMBALSE DE ABASTECIMIENTO DE AGUA EN LA PAZ, BOLIVIA

El embalse Milluni Grande depende principalmente de la precipitación, siendo vulnerable ante periodos de sequía, de forma que puede afectar a la seguridad hídrica de las ciudades de La Paz y El Alto. Por lo tanto, el presente estudio busca determinar la variación de la cantidad de agua disponible en el embalse bajo el set de escenarios de cambio climático establecidos en el quinto informe del Panel Intergubernamental sobre el Cambio Climático (IPCC) para el periodo 2022-2090. El área de estudio se limitó a la microcuenca Milluni, tomando el embalse Milluni Grande como punto de desemboque. La modelación hidrológica se realizó mediante la herramienta Water Evaluation and Planning System (WEAP) utilizando el ensamble de datos diarios de precipitación y temperatura generado a través de la herramienta Gridded Meteorological Ensemble Tool (GMET). Se incorporaron los escenarios de cambio climático empleando el Modelo 1 del Sistema Terrestre de Noruega NorESM1-M, reduciendo su escala mediante el método no paramétrico de vecinos más cercanos (knn-bootstrap). Se obtuvieron las siguientes tendencias para el periodo y área de estudio: incremento general de temperatura, incremento de precipitación en época seca y reducción de precipitación en época húmeda, lo cual puede generar situaciones de sequía. Por otra parte, el caudal de entrada al embalse Milluni Grande tiene tendencia a variar de forma directamente proporcional a la precipitación, mientras que su volumen tiene tendencia a reducirse. Asimismo, puede existir un déficit en la cobertura de los requerimientos de los sitios de demanda, llegando a valores mínimos de 45% para el sistema de distribución Achachicala y 27% para el sistema Meseta. Todos los resultados son acentuados en el escenario pesimista RCP 8.5.
Beta ridge regression estimators: simulation and application

Abstract The beta regression model is commonly used when analyzing data that come in the form of rates or percentages. However, a problem that may encounter when analyzing these kinds of data that has not been investigated for this model is the multicollinearity problem. It is well known that the maximum likelihood (ML) method is very sensitive to high inter-correlation among the explanatory variables. Therefore, this paper proposes some ridge estimators for the beta regression model to remedy the problem of instability of the traditional ML method and increase the efficiency of estimation. The performance of ridge estimators is compared to the ML estimator through the mean squared error (MSE) and the mean absolute error (MAE) criteria by conducting a Monte-Carlo simulation study and through an empirical application. According to the simulation and application results, the proposed estimators outperform the ML estimator in terms of MSE and MAE.
Serial RRAM Cell for Secure Bit Concealing

Non-volatile memory cells are exposed to adversary attacks since any active countermeasure is useless when the device is powered off. In this context, this work proposes the association of two serial RRAM devices as a basic cell to store sensitive data, which could solve this bothersome problem. This cell has three states: ‘1’, ‘0’, and masked. When the system is powered off or the data is not used, the cell is set to the masked state, where the cell still stores a ‘1’ or a ‘0’ but a malicious adversary is not capable of extracting the stored value using reverse engineering techniques. Before reading, the cell needs to be unmasked and it is masked afterwards until the next reading request. The operation of the cell also provides robustness against side-channel attacks. The presented experimental results confirm the validity of the proposal.
Exploring the potential of cycloidal computed tomography for advancing intraoperative specimen imaging

A preliminary investigation into the use of cycloidal computed tomography for intraoperative specimen imaging is presented. Intraoperative imaging is applied in time-sensitive clinical settings, where obtaining a high-resolution, highquality image within minutes is paramount in evaluating the success of operations and/or the need for additional surgery. As a flexible imaging method that is compatible with x-ray phase contrast imaging, cycloidal computed tomography can provide both high spatial resolution and high image contrast, whilst keeping scan times short thanks to an effective under-sampling approach. To gather early evidence, the method was tested on resected breast and oesophageal tissue. The results, although preliminary, indicate that cycloidal imaging may indeed be beneficial for intraoperative specimen imaging, although further studies are required to confirm this potential.
Potential Impact of Photoinhibition on Microphytobenthic Primary Production on a Large Intertidal Mudflat

Microphytobenthos (MPB) are a key primary producer of intertidal mudflats. MPB face strong variability in incident irradiance during low tides. Despite photoprotection and photoacclimation, such variations can translate into the photoinhibition of MPB cells. This study explores the effect of photoinhibition on MPB primary production (PP) over a large and productive temperate mudflat (Brouage mudflat, NW France). We used a regional and high‐resolution tri‐dimensional hydrodynamic model coupled to an MPB model with or without photoinhibition. Photoinhibition leads to a 20% (−0.79 × 103 t C) decrease of the simulated MPB PP over the entire mudflat. As the upper shore is exposed to light more frequently and longer than the lower shore, the decrease of MPB PP is higher on the upper shore (−29%) than on the lower shore (−5%). With the highest photosynthetically active radiation cumulated over the mudflat, the decrease of MPB PP due to photoinhibition is the highest during spring and spring tides (−22% and −23%, respectively). The model suggests MPB photoinhibition is sensitive to the photoacclimation status of MPB cells through the light saturation parameter. This first modeling attempt to account for MPB photoinhibition is highly constrained by our current theoretical knowledge and limitations on the MPB growth physiology, but it suggests that this process can have a substantial impact on the MPB PP. As such, assessing the MPB photosynthetic response to the highly variable environmental conditions that prevail in large and productive intertidal mudflats is a real challenge for quantifying MPB PP from a synoptic to inter‐annual time scale.

Surge voltage reduction method for dual active bridge matrix converter using circulating current

This paper proposes an extended method of zero‐voltage switching (ZVS) range for a dual active bridge (DAB) matrix converter with a discontinuous current mode (DCM). In the traditional DAB converter, ZVS cannot be achieved at a light load condition. The duty ratio calculation to achieve power factor correction and ZVS is explained using a circulating current. From the experimental results using a 5‐kW prototype, the ZVS operation with zero transmission power is achieved by increasing the circulating current. In addition, the grid current distortion is lower than 5.0% at the rated power regardless of the DC voltage variation of plus or minus 20%.
Mutual Trust in the City Strategy Implementation

: This chapter describes benefits of simultaneous implementation of data co-production and co-pro-cessing in crisis management to carry out joint operations of city divisions. Operations are part of the pre-paredness process, which sustain situational awareness of the common resource-based view. Based on the action research, the choice of spreadsheet software was a function for emergency management team, which strengthen mutual trust of the team members. The use of tool brought benefits to the value chain securing by taking into account the customer-oriented functions of the city, and co-processed data analysing. The goal of the value chain securing is to maintain, for example, cost-effective, waste-free assistant logistics, which implements city strategy during the crisis. Experience-based information in the chapter is valuable to assess the implementation of the strategies, and to creating opportunities accelerate recovery from the crisis.
Relative entropy-based modulation format identification for coherent optical communication system

Modulation format identification (MFI) is widely used in elastic optical networks, such as optical performance monitoring and signal compensation. We propose an MFI scheme, through extraction of the amplitude probability distribution feature of the received signals and an analysis of the relative entropy, which is also known as the Kullback–Leibler divergence (KL). The modulation formats (MFs) can be distinguished via calculation of the KL value. Through this method, four commonly used transmission formats were investigated, namely, polarization-division multiplexing (PDM)-QPSK/16QAM/32QAM and 64QAM. A simulation transmission model was created, and the results were analyzed. The simulation results show that the MFs investigated can be distinguished when the optical signal-to-noise ratio (OSNR) is less than or equal to the corresponding theoretical 7% forward error correction (FEC) limit (bit error ratio = 3.8 × 10 − 3). In addition, two important factors, i.e., fiber nonlinearity and sample size, were investigated in relation to the proposed method. The results show that the method exhibits a certain tolerance to fiber nonlinearity and can be used to identify the MF at the FEC threshold even when the sample number is 1000. Furthermore, the experimental verifications were conducted to ensure the practicality of the proposed method.
Risk Management in Digital Advertising: An Analysis from the Advertisers’ Media Management Perspective

ABSTRACT For advertisers, media management is the downstream part of advertising: After creative content is produced, advertisers manage different distribution channels to reach the right target audiences in efficient and effective ways. In the last five years, new technologies have disrupted this space and supported the exponential growth of digital advertising. Creative content may be distributed via internet-connected devices, such as desktop, mobile, or connected TV. Advertisers must understand the benefits and risks of each channel to best allocate their marketing budgets and drive both growth and cost savings. Tech and data-driven digital advertising promises many benefits to advertisers, ranging from precision targeting and measurable results to automation and real-time optimization. At the same time, advertisers face major challenges from a host of actors in the media ecosystem that often have misaligned incentives. Several studies have investigated how digital advertising activities affect business results in order to understand their positive and negative impacts. Very few studies, however, have focused on risk management in relation to digital advertising. In this article, we aim to fill this gap. Specifically, we identify the main risks in the paid distribution of digital advertising and the corresponding mitigation strategies. We examined digital advertising from the advertisers’ media management perspective. Interestingly, we found that risks and corresponding mitigation strategies can be clustered in specific groups that can help chief marketing officers and media executives drive the right actions.
Interaction of miR-146a-5p with oxidative stress and inflammation in complications of type 2 diabetes mellitus in male rats: Anti-oxidant and anti-inflammatory protection strategies in type 2 diabetic retinopathy

Objective(s): This study aimed to evaluate the role of miR-146a-5p in the pathogenesis of diabetic retinopathy and its interaction with oxidative stress and inflammation in the ocular tissue of rats with type 2 diabetes mellitus (T2DM). Materials and Methods: Twenty adult male Sprague Dawley rats (220 ±20 g) were randomly assigned to control and diabetic groups. A high-fat diet was used for three months to induce T2DM which was confirmed by the HOMA-IR index. After that, the levels of glucose and insulin in serum, HOMA-IR as an indicator of insulin resistance, the ocular level of oxidative markers, TNF-α, IL-1β, MIPs, and MCP-1 along with ocular gene expression of NF-κB, Nrf2, and miR-146a-5p were evaluated. Results: The level of lipid peroxidation along with metabolic and inflammatory factors significantly increased and the antioxidant enzyme activity significantly decreased in diabetic rats (P<0.05). The ocular expression of NF-κB and TNF-α increased and Nrf2, HO-1, and miR-146a-5p expression decreased in diabetic rats (P<0.05). In addition, a negative correlation between miR-146a-5p expression with NF-κB and HOMA-IR and a positive correlation between miR-146a-5p with Nrf2 were observed. Conclusion: It can be concluded that miR-146a-5p may regulate Nrf2 and NF-κB expression and inflammation and oxidative stress in the ocular tissue of diabetic rats.
Standardized Management Systems in the Context of Active Employee Participation in Occupational Health and Safety

Purpose: This paper seeks to conceptualize and clarify the active employee participation in health and safety (taking into account scope and depth ) and develop a scale to measure it and use this indicator in practice for comparative analysis. Design/Methodology/Approach: The conceptual and theoretical model for employee participation in OHS is tested on a sample of 289 respondents. The research was conducted using the PAPI (Paper & Pen Personal Interview) method. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used. The developed construct (characterized by an adequately high level of validity and reliability) was used to compare companies in the implemented management system. In comparative analysis was used Mann–Whitney U test. Findings: It was found that it is possible to measure active participation in OHS (EFA and CFA analyzes) and that proactive indicator consists of one dimension (15 items). The comparative analyses conducted corroborate the relationship between implementing a standardized management system and a level of active participation of employees in OHS. Practical Implications: The measurement and identification of determinants impacting on a high level of employee engagement in OHS will allow the management to take adequate and effective actions in respect of the safety of all organization members because employee participation in OHS is a condition necessary for the successful implementation of OHS management system and establishing high OHS culture which is correlated with a level of security in the company. Originality/Value: The study presents an original approach to the problem of active participation in OSH - completes the theoretical gap. To the best of our knowledge, this is the first study to provide a comprehensive, psychometrically sound, operationally valid measure of participation in OHS. The model for active employee participation in OHS and the universal measurement scale developed and validated in this study represents a step forward towards the effective and reliable measurement of employee participation.
The Origin of Late Cenozoic Magmatism in the South China Sea and Southeast Asia

Basaltic lavas sample recycled crustal materials from their mantle source. Constraining the location and residence time of these recycled materials in the mantle is critical to understand global mantle dynamics. In this study, we present new whole‐rock major and trace element abundances, Sr‐Nd‐Mo‐Os isotopes, water contents and He isotopes of volcanic glasses, U‐Pb ages of zircons, and compositions of melt inclusions, spinels and olivines from the South China Sea (SCS) seamounts lavas. These new data are compared with literature data from intraplate volcanism of similar age from Southeast (SE) Asia. The isotope data of late Cenozoic lavas from the SCS seamounts and SE Asia can be explained by mixing between enriched mantle 2 (EM2) and depleted mid‐ocean ridge basalt mantle components. Our data are consistent with the EM2 signature of late Cenozoic lavas derived from recycled young oceanic crust and sediments. The compositions of olivine phenocrysts indicate an olivine‐dominated (peridotitic) mantle source. There is currently no evidence for a high‐3He/4He mantle plume component beneath the SCS. Our results combined with geophysical data and plate reconstructions suggest that the late Cenozoic magmatism is related to the upwelling of instabilities from the mantle transition zone (MTZ) triggered by a stagnant slab. The SCS seamount lavas sample an enriched MTZ containing young recycled materials, consistent with regional past subduction. Our study provides additional evidence that storage and recycling of crustal materials in or near the MTZ is an important mechanism to develop global mantle heterogeneities sampled by intraplate volcanoes.
Binary and Rotational Coded-Aperture Imaging for Dynamic Light Fields

SUMMARY Coded-aperture imaging has been utilized for compressive light ﬁeld acquisition; several images are captured using di ﬀ erent aperture patterns, and from those images, an entire light ﬁeld is computationally re-constructed. This method has been extended to dynamic light ﬁelds (moving scenes). However, this method assumed that the patterns were gray-valued and of arbitrary shapes. Implementation of such patterns required a special device such as a liquid crystal on silicon (LCoS) display, which made the imaging system costly and prone to noise. To address this problem, we propose the use of a binary aperture pattern rotating along time, which can be implemented with a rotating plate with a hole. We demonstrate that although using such a pattern limits the design space, our method can still achieve a high reconstruction quality comparable to the original method. key words: light ﬁeld, CNN, coded aperture camera
