Privacy and user awareness on Facebook

Users’ privacy on social media platforms continues to be important as users face numerous threats to their personal data. Social media sites such as Facebook store large amounts of users’ personal data which make such sites prime targets for hackers. Research has shown that users have been subjected to privacy attacks in which hacked personal data are sold to online marketers. These incidents have prompted the need to protect users’ privacy against data theft by third parties. We investigated the privacy risks that social media users on Facebook face when online. The privacy awareness of regular users of Facebook was evaluated through the observation of their online activities. Facebook was selected as a case study because it is the largest and most popular social media platform in South Africa. A sample group of Facebook users was selected for this study based on their activeness (or frequency of posting, uploaded or liking) on the site. Findings indicate that users’ personal data can be obtained as they are publicly available on Facebook. The implication of this finding is that users lack adequate awareness on protection tools designed to protect their personal data, and as a result, they risk losing their data and privacy. Significance: • This study serves as an assessment tool for the privacy and security features of the social media site Facebook. This assessment tool can help users of social media sites to evaluate their own behaviour and usage patterns on Facebook. It can also assist social media site designers in considering the effectiveness of current measures, which are designed to ensure that the privacy and safety of users are protected.
Just a Matter of Time? Women’s Career Advancement in Neo-Liberal Academia. An Analysis of Recruitment Trends in Italian Universities

Recently, the Italian higher education system has experienced two profound changes: the strong feminization of its academic staff and the implementation of market-based reforms aimed at fostering cost efficiency and economic productivity. Such reforms include the reshaping of the academic career ladder envisaged by the last university reform, the so called Gelmini reform (law 240/2010), and the adoption of a performance-based funding system. Both elements occurred in parallel with a strong cut in turnover. By accessing unique data on recruitment covering the last two decades, which were provided by the Italian Ministry of Education, University, and Research’s statistical office, this study aims at investigating these changes from a gendered perspective. More specifically, it firstly aims at analyzing if the feminization of the academic staff is due to an effective improvement of gender equality in recruitment or, rather, to demographic dynamics; secondly, it investigates to what extent the recent neo-liberal transformations, and more specifically the reshaping of the career structure combined with the limitations on hiring, has had any implications in terms of women’s recruitment and advancement. The results suggest that the road to gender equality is extremely slow and non-linear. The introduction, with the Gelmini reform, of the new fixed-term assistant professor has tightened female access to the tenure track. Moreover, female recruitment remained substantially unchanged over the period among associate and full professors, thus suggesting that the feminization of the academic staff is not due to an effective improvement of gender equality in recruitment, but also to demographic dynamics, such as the retirement of men who are concentrated in the older cohorts.
Observations of Flow Separation and Mixing around the Northern Palau Island/Ridge

Turbulent mixing adjacent to the Velasco Reef and Kyushu–Palau Ridge, off northern Palau in the western equatorial Pacific Ocean, is examined using shipboard and moored observations. The study focuses on a 9-day-long, ship-based microstructure and velocity survey, conducted in November–December 2016. Several sections (9–15 km in length) of microstructure, hydrographic, and velocity fields were acquired over and around the reef, where water depths ranged from 50 to 3000 m. Microstructure profiles were collected while steaming slowly either toward or away from the reef, and underway current surveys were conducted along quasi-rectangular boxes with side lengths of 5–10 km. Near the reef, both tidal and subtidal motions were important, while subtidal motions were stronger away from the reef. Vertical shears of currents and mixing were stronger on the northern and eastern flanks of the reef than on the western flanks. High turbulent kinetic energy dissipation rates, 10−6–10−4W kg−1, and large values of eddy diffusivities, 10−4–10−2m2s−1, with strong turbulent heat fluxes, 100–500 W m−2, were found. Currents flowing along the eastern side separated at the northern tip of the reef and generated submesoscale cyclonic vorticity of about 2–4 times the planetary vorticity. The analysis suggests that a torque, imparted by the turbulent bottom stress, generated the cyclonic vorticity at the northern boundary. The northern reef is associated with high vertical transports resulting from both submesoscale flow convergences and energetic mixing. Even though the area around Palau represents a small footprint of the ocean, vertical velocities and mixing rates are several orders magnitude larger than in the open ocean.

5G: the Network of the Future. Benefits and Perils

The fifth generation mobile network (5G) is a set of emerging global telecommunications standards, generally using high-frequency spectrum, to offer network connectivity with reduced latency and greater speed and capacity relative to its predecessors. One example is emerging autonomous cars and intelligent transportation, to which small latency is essential. It is argued that the current communications infrastructure is highly energy-inefficient and the 5G should be designed to solve this problem, by increasing energy efficiency by several orders of magnitude. To meet 5G requirements, we need dramatically new network architectures and technologies, such as heterogeneous ultra-dense networks, massive multiple-input-multiple-output (MIMO), and millimetre wave communications.
Alteraciones hematológicas encontradas en caballos (Equus caballus) infectados con Babesia caballi y Theileria equi

The intraerythrocytic parasites Babesia caballi and Theileria equi are the etiological agents of equine piroplasmosis. This disease affects different horse breeds and it has a significant economic impact on the horse industry. The objective of the present study was to determine the presence of B. caballi and T. equi by blood smear and their association with the hematological parameters. Fifty-eight blood samples were taken from clinically healthy horses, which were diagnosed with B. caballi and T. equi infections by blood smear; in addition, the hematological examination of the red and white series was carried out. The mean value of all the hematological parameters evaluated was among the physiological values described for the horse species. From the total samples analyzed, intraerythrocytic formations compatible with B. caballi and T. equi were observed in 3/58 (5.2 %) and 8/58 (13.8 %) animals, respectively. Of these animals, 6/11 (10.3 %) had hematocrit values lower than those physiological. The association between positive animals and possible risk factors (age, sex, presence of ticks and contact with bovines) was evaluated. The statistical analysis showed significant differences when evaluating the relationship between hematocrit values and positive samples to T. equi . 0 Links
A Technique for Better Energy Management of Single-Stage Topology of Stand-Alone Photovoltaic System

This paper proposes a technique for the energy management of a stand-alone photovoltaic system. The proposed system employs a power processing inverter that has a high PV voltage at the input to mitigate the magnitude of AC signal at the output, thus eliminating the use of DC-DC converter and reducing the input capacitor size of PV array. To meet the power requirement of load and to maintain the maximum power point operation of PV array, a battery bank is utilized with a bi-directional converter. An impedance model of the complete system is executed. Based on the model, the control architecture is designed which works in four modes: 1) if load demands > MPP of PV, additional current is extracted from the battery; 2) if load demands < MPP of PV array, extra current is given to the battery; 3) only load management is utilized since the battery bank is not available because of overcharging or under-charging; 4) if irradiation varies then the first mode is used for load requirement. The technique is designed which guarantees the maximum power point tracking of the PV system even without using any intermediate stage of a DC-DC converter, hence making it a single-stage system. MPPT is achieved by effectively controlling the bi-directional converter used for battery charging and discharging purposes. To ensure better utilization of dc voltage, enhanced efficiency, and low less harmonic distortion, a sinusoidal PWM technique is used to drive the inverter. Simulation results are carried out for ensuring better energy management along with MPPT operation demonstrated under uniform operating conditions.
Replacing fish meal with a blend of poultry by-product meal and feather meal in diets for giant croaker (Nibea japonica).

An 8-week feeding trial was conducted to evaluate the potential of replacing fish meal with poultry by-product meal (PBM) and feather meal (FEM) in giant croaker (Nibea japonica) diet. The control diet (C) contained 400 g/kg fish meal, and 20%, 40%, 60% and 80% of the fish meal in diet C was replaced by a blend of PBM and FEM (PBM: FEM = 7:3) in diets B20, B40, B60 and B80, respectively. The weight gain and feed intake of fish fed diet C did not differ from those of fish fed diets B20 and B40 (p > .05), but were higher than those of fish fed diets B60 and B80 (p .05). Ratio of fish meal consumption to fish production linearly declined with the decrease in dietary fish meal level. This study indicates that dietary fish meal for giant croaker could be reduced to 240 g/kg by inclusion of the blend of PBM and FEM.
Body-Centric Terahertz Networks: Prospects and Challenges

Following recent advancements in Terahertz (THz) technology, THz communications are currently being celebrated as key enablers for various applications in future generations of communication networks. While typical communication use cases are over medium-range air interfaces, the inherently small beamwidths and transceiver footprints at THz frequencies support nano-communication paradigms. In particular, the use of the THz band for in-body and on-body communications has been gaining attention recently. By exploiting the accurate THz sensing and imaging capabilities, body-centric THz biomedical applications can transcend the limitations of molecular, acoustic, and radio-frequency solutions. In this paper, we study the use of the THz band for body-centric networks, by surveying works on THz device technologies, channel and noise modeling, modulation schemes, and networking topologies. We also promote THz sensing and imaging applications in the healthcare sector, especially for detecting zootonic viruses such as Coronavirus. We present several open research problems for body-centric THz networks.
Equatorial Pacific Warming Attenuated by SST Warming Patterns in the Tropical Atlantic and Indian Oceans

Most climate models project an enhanced mean sea surface temperature (SST) warming in the equatorial Pacific and Atlantic, and a zonal SST dipole in the Indian Ocean. The remote influences of these SST change patterns remain uncertain. To examine the extent to which the patterns of SST changes in the tropical Indian and Atlantic Oceans modulate the warming in the tropical Pacific Ocean, we compare nudging experiments with prescribed structured and uniform SST changes in the tropics outside the Pacific. We find that the warming patterns in the tropical Indian and Atlantic Oceans, respectively, drive a canonical La Niña‐like and elongated equatorial cooling through the Bjerknes feedback, acting to attenuate the warming in the equatorial Pacific substantially. The different SST cooling responses emanate from subtle differences between the initial wind forcing driven by the two basins' SST change patterns. These results have significant implications for future climate change projections.
Residents’ Spatial Perceptions of Urban Gardens Based on Soundscape and Landscape Differences

In this study, four types of urban gardens, namely modern commercial, cultural heritage, historical preservation, and natural and ecological areas, were comprehensively described and analyzed based on soundscape and landscape differences, and a multinomial logit model was used to explore potential influencing factors shaping residents’ preferences regarding urban gardens. The results suggest that variations in soundscape are closely related to the characteristics of the garden areas and the timing of residents’ activities; the noise level measurements at different observation points varied considerably according to the time of day and displayed different trends. Residents strongly preferred natural sounds, and traffic noise was the most disliked category of sound. Further, a negative correlation was found between residents’ subjective perception of loudness and the favorability of the area, while a clear positive correlation existed between the degree of favorability and the degree of landscape-soundscape coordination. Regarding landscape differences, residents generally preferred urban gardens without artificial transformation and prioritized the maintenance of natural landscaping and the historical and cultural heritage of urban gardens. In particular, residents’ preferences reflected the trade-offs between natural and artificial forms of urban gardens. These results offer useful information for planners, developers, and governmental organizations related to urban gardens by providing data to design urban gardens with increased practical value and natural benefits.
“We Are the Forgotten of the Forgottens”: The Effects of Charter School Reform on Public School Teachers

In this article, Erika Kitzmiller analyzes the reactions of teachers to district officials’ decision to close their traditionally managed public school and reopen it as a privately managed charter school. While many scholars have examined the impact of this reform on communities, families, and youth, little attention has been paid to the effects of charter school reform on the public school teachers who worked in these schools. Here Kitzmiller considers one of the key but largely overlooked stakeholders in charter school reform: public school teachers.
A Conceptual Investigation at the Interface between Wireless Power Devices and CMOS Neuron IC for Retinal Image Acquisition

In this paper, a conceptual investigation of the interface between wireless power devices and a retina complementary metal oxide semiconductor (CMOS) neuron integrated circuit (IC) have been presented. The proposed investigation consists of three designs: design-I, design-II, and design-III. Design-I involves a slotted loop monopole antenna as per American National Standards Institute (ANSI) guidelines, which achieve an ultra-wide band ranging from 3.1 GHz to 10.6 GHz. The biocompatible antenna is made on silicon-nitride substrate using on-wafer packaging technology and it is used as a receiver device. The performance of antenna provides a wideband, sufficient power to receive, and low losses due to the avoidance of printed circuit board (PCB) fabrication. A CMOS based multi-stack power harvesting circuit achieves the output power ranging from 4 mW to 2.7 W and corresponds from the selected Radio Frequency (RF) bands of loop antenna is exhibited in design-II. The power efficiency of 40% to 82%, with respect to output powers of 4 mW to 2.7 W, is achieved. Design-III includes a CMOS based retina neuron circuit that employs a dynamic feedback technique and support to achieve the number of read-out spikes. At the end of the interface between wireless power devices and a CMOS retina neuron IC, 50 mV read-out spikes are achieved, with varying light intensity, from 0 mW/cm2 to 2 mW/cm2. The proposed design-II and design-III are implemented and fabricated using commercial CMOS 0.065 µm, Samsung process. The antenna and RF power harvesting IC could be placed on a contact lens platform while retina neuron IC can be implanted after ganglions cells inside the eye. The antenna and harvesting IC are physically connected to the retina circuit in the form of light. This conceptual investigation could support medical professionals in achieving an interfacing approach to restore the image visualization.
High-Torque Oscillating Wind Energy Generator

This research investigates a novel concept in small-scale wind-energy generation. Instead of rotating turbine blades, the present concept produces reciprocating motion that is achieved by alternately activating boundary layer control (slot blowing) on opposite sides of a circular cylinder. This is commonly called the Coandă-effect, and here we deploy it periodically on a spring-stabilized vertical cylinder, to produce reciprocating motion. This Co andă-based Re ciprocating (CoRe) system converts wind energy to mechanical work. Compared to wind turbines and windmills, the CoRe system generates higher torque and is therefore well suited to directly driving positive displacement pumps for drip-irrigation or reverse osmosis water desalination. This new approach necessitates the investment of energy in order to extract energy from the wind and therefore a major challenge is to maximize the output/input ratio in order to render the concept viable. Previous preliminary wind tunnel tests conducted on the CoRe system produced gross and net power coefficients of 10% and 3% respectively. However, the blowing slot design has a decisive impact on output power. On the basis of data presented in the literature and our computational analysis, the CoRe system produces significantly greater torque than all types of wind turbines with net power coefficients over 10%.
Primary-Secondary Transition – Building Hopes and Diminishing Fears Through Drama

This case study explores how pupils might address the issues of bullying and friendships during primary-secondary transition through drama conventions. The research was implemented on the west coast of Scotland during the final four weeks of primary education in three associated primary seven classes. Research methods included pupil questionnaires (primary and secondary school), teacher observations, researcher’s diary, semi-structured interviews (teachers) and a focus group (pupils). The data suggest that some pupils conceptualized their primary-secondary transition as ‘moving up’. However, as the drama developed pupils recognized the multiple and multi-dimensional aspects of their transition. In addition, pupil and teachers indicated that when pupils engage with a drama transition curriculum, it supports the promotion of friendships while diminishes fears and provides strategies for those who might encounter bullying.
A Genre Analysis of Kurdish Death Announcement Notices

The present paper examines the genre of death announcement notices (DANs) in Kurdish. Those notices have been regularly used but never been subject to an academic investigation in the context of Kurdish language. This study aims at outlining the linguistic structure of DANs as well as the socio-cultural influences that contribute to their final composition. To illustrate the basic components of the notices, some 60 samples of women and men DANs or funeral posters, which were hanged in different locations such as mosques and major intersections of the research area were collected and analyzed using Swale’s (1990) genre move analysis. The analysis revealed three moves, namely, Signaling the Event, Identifying the Deceased and Funeral Arrangements as the obligatory components of the DANs in Kurdish. The notices were to some extent grounded in Islamic and Arabic traditions. Traces of gender bias were found in the corpus.
