On the Effect of Interference and Misalignment Error in Mixed RF/FSO Systems Over Generalized Fading Channels

In this paper, the end-to-end performance of a mixed radio frequency (RF)/free space optical (FSO) affected by co-channel interference (CCI), is studied. We consider that the RF link experiences <inline-formula> <tex-math notation="LaTeX">$\eta -\mu $ </tex-math></inline-formula> fading and the FSO link is subjected to atmospheric turbulence, which is modeled by the <inline-formula> <tex-math notation="LaTeX">$\alpha -\mu $ </tex-math></inline-formula> distribution. Also, the statistics of the FSO link is presented for the case of zero and non-zero boresight pointing errors. Furthermore, we assume intensity modulation with direct detection (IM/DD) and coherent demodulation. In particular, we present a closed-form expression for the probability density function of the FSO link, which is then used to obtain a closed-form and an asymptotic expression for the outage probability. In order to quantify the system performance, we utilize this asymptotic result to yield the system’s coding gain and diversity order. Moreover, we have presented analytical expressions for the average bit error rate (BER) and ergodic capacity for the system design. In order to gain more insights, high signal-to-noise ratio (SNR) approximations expressions for the BER and ergodic capacity, are also derived. Finally, the analytical results presented in the paper are validated through computer simulations.
Comparative Analysis of MLR, ANN, and ANFIS Models for Prediction of Field Capacity and Permanent Wilting Point for Bafra Plain Soils

ABSTRACT Soil hydraulic parameters like moisture content at field capacity and permanent wilting point constitute significant input parameters of various biophysical models and agricultural practices (irrigation timing and amount of irrigation to be applied). In this study, the performance of three different methods (Multiple linear regression – MLR, Artificial Neural Network – ANN and Adaptive Neuro-Fuzzy Inference System – ANFIS) with different input parameters in prediction of field capacity and permanent wilting point from easily obtained soil characteristics were compared. Correlation analysis indicated that clay content, sand content, cation exchange capacity, CaCO3, and organic matter had significant correlations with FC and PWP (p < .01). Validation results revealed that the ANN model with the greatest R2 and the lowest MAE and RMSE value exhibited better performance for prediction of FC and PWP than the MLR and ANFIS models. ANN model had R2 = 0.83, MAE = 2.36% and RMSE = 3.30% for FC and R2 = 0.81, MAE = 2.15%, RMSE = 2.89% for PWP in training dataset; R2 = 0.80, MAE = 2.27%, RMSE = 3.12% for FC and R2 = 0.83, MAE = 1.84%, RMSE = 2.40% for PWP in testing dataset. Also, Bayesian Regularization (BR) algorithm exhibited better performance for both FC and PWP than the other training algorithms.
Justice-restoring responses: a theoretical framework for understanding citizen complaints against the police

ABSTRACT In an effort to provide a theoretical framework for understanding citizens’ decisions to complain about the police, this paper suggests that citizen complaints can be viewed as a justice-restoring response and tests six hypotheses using a factorial vignette experiment. The findings indicate that individuals are more likely to complain when they perceive the interaction as procedurally unfair, distributively unfair, and when the outcome is unfavourable. Positive pre-existing attitudes towards the police result in an increased likelihood of engaging in a justice-restoring response. Despite drawing on Tyler’s legitimacy theory, these findings differentiate justice-restoring responses from legitimacy by the comparatively greater impact of outcome favourability and the differing direction of the effect of pre-existing attitudes towards the police.
The Ethics of Human Intervention on Behalf of ‘Others'

I regularly pass several homeless persons surviving on the streets even in winter. One sits on a folded scrap of a blanket leaning against a wall looking thin, pale and resigned, doing some calligraphy of messages on card for those who want them. Almost everyone walks quickly past, some manoeuvring to the opposite side of the wide pavement, others almost treading on some of their sparse belongings. Hardly anyone makes eye contact. The harsh reality of living on the street is some days without enough food and basic provisions.
Enacting education policy reform in Portugal – the process of change and the role of teacher education for inclusion

ABSTRACT The international trend to develop inclusive systems, has resulted in pressure on national governments to develop policies that promote quality education for all. In 2017–18 Portugal has adopted progressive educational policies with regards to inclusive education, that attempt to reconcile school values, curriculum and pedagogies. This article critically analyses changes proposed by this wave of educational policy reform and establishes the need for a strong continuous professional development of mainstream teachers to support them to develop as reflexive and inclusive practitioners. The analysis applies two models of change to examine the ‘policy ecology’ and consider the initiatives used to enact change in Portuguese schools. The policies have prioritised the development of schools in which all students are welcome, able to participate and succeed. While this wave of policy reform has relied both on formal and non-formal forms of teacher education, there is a danger of superficial approaches that may not support teachers in the process of change.
Bursting the Filter Bubble: Fairness-Aware Network Link Prediction

Link prediction is an important task in online social networking as it can be used to infer new or previously unknown relationships of a network. However, due to the homophily principle, current algorithms are susceptible to promoting links that may lead to increase segregation of the network—an effect known as filter bubble. In this study, we examine the filter bubble problem from the perspective of algorithm fairness and introduce a dyadic-level fairness criterion based on network modularity measure. We show how the criterion can be utilized as a postprocessing step to generate more heterogeneous links in order to overcome the filter bubble problem. In addition, we also present a novel framework that combines adversarial network representation learning with supervised link prediction to alleviate the filter bubble problem. Experimental results conducted on several real-world datasets showed the effectiveness of the proposed methods compared to other baseline approaches, which include conventional link prediction and fairness-aware methods for i.i. d data.
The (negative) impact of supply-side labour market reforms on productivity: an overview of the evidence1

In spite of impressive stories about artificial intelligence or Industry 4.0, the USA, Japan and Western Europe experience a severe productivity crisis since about 2005. This article fills a gap in recent attempts at understanding the productivity crisis, arguing that there is a negative impact of supply-side labour market reforms on innovation and productivity. The negative impact of more flexible labour relations is significant in medium-high and high-tech sectors with a high ‘cumulativeness’ of knowledge, that is if the historical accumulation of firm-specific and often tacit knowledge is important for innovative competencies. In low-tech sectors as well as for high-tech entrepreneurship, where cumulativeness of knowledge is low, there is little or no effect.
Association Between Cigarette Package Warning Messages, Self-Efficacy, and Smoking Behavior Among Students at Health Polytechnic in Surakarta, Indonesia

Background: Total number of smokers around the worldwide is approximately 140 million. The number of deaths caused by tobacco smoking related diseases is approximately 300,000 per year. Average age to start smoking is 17.6 years. The high number of smokers at young age indicates that public awareness of the dangers of smoking is still very low. This study aimed to determine the association between cigarette package warning messages, self-efficacy, and smoking behavior among students.Subject and Methods: This was an analytical observational study with cross sectional design, carried out in Surakarta, Indonesia. A total of 71 students at Polytechnic of health and sciences were selected by using random sampling technique. The dependent variable was smoking behavior. The independent variables were illustrated the dangers of cigarette smoking advertising and self-efficacy. The data was collected by questionnaire and analyzed by using regression logistic.Results: there is a relationship between an ad illustrated the dangers of cigarette smoking with smoking behavior (OR= 2.87; 95% CI= 0.91 to 9.03; p = 0.071). There is a relationship between the smoking behavior of yourself with the efficacy (OR = 0.23; 95% CI= 0.07 to 0.74; p = 0.013). The ads illustrated the dangers of cigarette smoking and self-efficacy was able to explain the smoking behavior of 16.2% and amounted to 83.8% explained by factors other than the research model.Conclusion: there is a connection between the ads illustrated the dangers of cigarette smoking and the smoking behavior of self-efficacy with the students.Keywords: cigarette package warning messages, self-efficacy, smoking behaviorCorrespondence: Roy Romey Daulas Mangunsong.

Corporate governance and turnaround: Evidence from Australia

We examine the relationship between ownership and outside director attributes and corporate turnaround outcomes using matched samples of 99 turnaround and 99 non-turnaround listed Australian firms during the 2004–2015 period. Based on agency theory principles, we propose that key shareholder groups (block ownership, director ownership, institutional ownership) and outside directors are related to firm-level turnaround outcomes, and particularly changes in these attributes across decline to turnaround periods. Our results provide evidence that turnaround and non-turnaround firms differ in terms of their ownership and board composition structures, and that changes in director ownership and the degree of board independence are important in determining the likelihood of turnaround success.

Optimal Energy-Delay Scheduling for Energy-Harvesting WSNs With Interference Channel via Negatively Correlated Search

Network resource allocation is an important issue for designing energy-harvesting wireless sensor networks (EH-WSNs). This article considers the capacity assignment problem in EH-WSNs with the interference channel for fixed data and energy flow topologies. We focus on the optimal data rates, power allocations, and energy transfers, minimizing the total network delay for the network. We first consider a simplified model where the data flow is fixed on each data link and optimizes transmit power at each sensor node for a single energy harvest in a time slot. However, the optimization problem is nonconvex, making it difficult to find the optimal solution. Unlike the most traditional methods that approximate the original optimization problem as a convex optimization problem by considering the relatively high signal-to-interference-plus-noise ratio (SINR), this article aims to directly solve the original nonconvex formulation by employing a powerful evolutionary algorithm, i.e., negatively correlated search (NCS). Then, we investigate the joint optimization problem of capacity and flow for the entire EH-WSNs, and develop a novel multiobjective NCS algorithm (MOEA/D-NCS) to deal with the complicated nonlinear constraints and optimize the data rates, power allocations, and energy transfer simultaneously, so as to minimize the total network delay. The numerical results demonstrate that solving the nonconvex problem with approximated approach is a good alternative for solving the approximated convex problem with accurate optimization approaches; the joint optimization of capacity and flow is a good solution for EH-WSNs; and the scheme of partial transmission for data flow is an advantage in respect of decreasing the network delay. The solution of this article could also be beneficial to other complex optimization problems in the wireless network design.
Layer-Specific Inhibitory Microcircuits of Layer 6 Interneurons in Rat Prefrontal Cortex

GABAergic interneurons in different cortical areas play important roles in diverse higher order cognitive functions. The heterogeneity of interneurons is well characterized in different sensory cortices, in particular in primary somatosensory and visual cortex. However, the structural and functional properties of the medial prefrontal cortex (mPFC) interneurons have received less attention. In this study, a cluster analysis based on axonal projection patterns revealed four distinct clusters of L6 interneurons in rat mPFC: Cluster 1 interneurons showed axonal projections similar to Martinotti-like cells extending to layer 1, cluster 2 displayed translaminar projections mostly to layer 5, cluster 3 interneuron axons were confined to the layer 6, whereas those of cluster 4 interneurons extend also into the white matter. Correlations were found between neuron location and axonal distribution in all clusters. Moreover, all cluster 1 L6 interneurons showed a monotonically adapting firing pattern with an initial high-frequency burst. All cluster 2 interneurons were fast-spiking, while neurons in cluster 3 and 4 showed heterogeneous firing patterns. Our data suggest that L6 interneurons that have distinct morphological and physiological characteristics are likely to innervate different targets in mPFC thus play differential roles in the L6 microcircuitry and in mPFC-associated functions.
Institutional responsibilities: providing placement for international students

ABSTRACT Recent years have seen a rapid increase in the number of international students studying health professional degrees such as social work in Australia and internationally. Research indicates that placement educators perceive that extra time and effort is required to support international students on placement due to, for example, language barriers and cultural and educational differences. This paper reports on findings from a nationwide study investigating the experiences and support needs of placement educators who supervise international social work students. The data consists of 15 in-depth interviews and 66 survey responses from placement educators across Australia. Findings reveal that placement educators feel pressure from education providers to supervise international students, yet they also feel they lack support from the education provider to do so adequately. Placement educators cite a need to increase contact and coordination between agencies and education providers, including clarity around the education providers’ expectations of their supervision. Placement educators want closer working relationships between agencies and education providers to ensure rewarding and enriching experiences for both students and placement educators. Such findings suggest that increased institutional support for, and collaboration with, placement educators is required to sustainably maintain quality placements for international students.

ABSTRACT Background and Aim: Neuropathic pain results from nerve injury and nortriptyline, an antidepressant drug, has been approved for the treatment of several types of neuropathic pain. In this study we investigated the antinociceptive effect nortriptyline (45mg/kg body weight) of nortriptyline on thermal and acetic acid induced pain in mice. Methods: nortriptyline was dissolved in distillated water and injected i.p to male mice 15 minute before the onset of experiment. Writhing and hot-plate tests were applied to study the analgesic effect of nortriptyline and compared with that of diclofenac sodium (30 mg/kg, i.p.) or morphine (8 mg/kg, i.p). To investigate the mechanisms involved in antinociception, glutamic acid, naloxone, yohimbine, atropine, propranolol and ondansetron were used. These drugs were injected intraperitoneally 15 min before the administration of nortriptyline. The number of writhes were counted in 30 minutes and analyzed. Results: In this study nortriptyline exhibited a significant antinociceptive effect in both chronic and acute pain in mice. The antinociceptive effect induced by this gum in the writhing and hot plate test was reversed by the systemic administration of propranolol (β-adrenergic antagonist) and ondansetron but glutamic acid, naloxone and atropine did not reverse this effect. Conclusion: The findings of this study indicated that nortriptyline induced its antinociceptive through the adrenergic and/ or serotonergic system.
Weighing Up the Evidence and Local Experience of Residential Care

Therapeutic residential care is currently seen as an answer to managing the increasing disruption experienced by many young people in care. Yet the history of residential care in Australia is problematic and the international evidence for the efficacy of therapeutic approaches is very poor. The author's own agency's experience of providing residential care also indicates that caution is needed before increasing the numbers of residential ‘beds’. Problems include young people's dislike of residential options and the stressfulness of an environment that involves shift workers and multiple transient relationships. Further, residential care can be a financial drain on child welfare budgets (being tendered to non-government agencies at over seven times the cost of community care), and has the potential danger – when beds are empty – of being used for young people who do not need this level of care. Residential care may appear to be the only option for a handful of adolescents no longer suited to foster care; but before developing therapeutic residential care further, government must be able to guarantee, at a minimum: a safe environment, a nurturing and healing environment, continuity of care, and the capacity to meet young people's developmental and permanency needs. These standards must be met, not just now, but over the long term.
Turning out to turn down the EU: the mobilisation of occasional voters and Brexit

ABSTRACT Large amounts of occasional voters participated in the Brexit referendum. Did the increase in turnout affect the referendum outcome? For an answer, we exploit exogenous variation in voting costs, as large amounts of rainfall made voting more inconvenient in some areas. With an instrumental variable approach, we show that citizens whose voting benefits just surpassed costs under normal circumstances predominantly supported Leave. Hence, the turnout increase likely led to a larger Leave vote share. Exploring the reason for this with survey data, we show that Leave support was not generally higher in the population of low-propensity voters. Rather, the mobilisation of Leave-leaning, compared to Remain-leaning occasional voters was lopsided: The former were more likely to turn out. Our research highlights that the issue-specific mobilisation of low-propensity voters helps to explain electoral outcomes. This is particularly so in referendums with weak partisan preferences, and where single issues dominate voter decision making.
Transforming Fair Decision-Making about Sea-Level Rise in Cities: The Values and Beliefs of Residents in Botany Bay, Australia

Sea-level rise (SLR) is a threat to coastal areas and there is growing interest in how social values, risk perception and fairness can inform adaptation. This study applies these three concepts to an urban community at risk of SLR in Botany Bay, Australia. The study engaged diverse groups of residents via an online survey. Cluster analysis identified four interpretive communities: two groups value work-life balance, are concerned about SLR and would likely engage in collective adaptation. The third group value everything about Botany Bay and are active in organisations that could prove to be an important outreach. The fourth group were older men, disengaged from both SLR and policy but could respond to individual consultation and targeted communication. Thus, multifarious approaches can engage diverse communities in fair decision-making and transform community-facilitated adaptation.
Drivers’ Perceptions of Events: Implications for Theory and Practice

People are known to naturally segment meaningful units of activity into individual events. Though an influential body of work demonstrating the relationship between event perception and human performance in daily tasks does exist, less consideration has been given to ideas that event perception can shape driving performance. This paper offers an introduction to event perception for the transportation community with a study measuring drivers’ perceptions for events in simulated driving scenes. The results demonstrate consistency in drivers’ perceptions of events and that specific features of a driving scene can predict event boundaries. This study also provides some evidence for a relationship between event perception and driving skill as measured by driving frequency. Discussed are the study’s implications to predict and shape the cognitive performance of drivers, along with potential benefits for driver training programs.
From cellular memory to the memory of trauma: Social epigenetics and its public circulation

Trauma is associated with the appearance of the concept of ‘accident’ as a social and legal entity, as well as with the successive discoveries of surgery, psychiatrics, and psychoanalysis. Today, epigenetics has redefined trauma as an extreme form of social adversity. Because of the exceptional nature of the events studied and also the social and political significance of its results, the social epigenetics of historical trauma has received undeniable public success. The present article investigates the general dynamics of this research front, as well as the forms and consequences of its public circulation. We highlight the specificity of the circulation modes associated with social epigenetics and the myriad ways it has been used socially and politically. This study addresses four registers of action in particular: to attest, to repair, to intervene, and to treat. The social circulation of the epigenetics of trauma is as influenced by the public’s willingness to see it as socially and politically relevant as it is by the ability of researchers to prepare this collective appropriation through different forms of public engagement. Finally this study allows us to refute the dichotomic conception of the genetics/epigenetics relationship, which is too frequently the foundation for making epigenetics academically acceptable in the social sciences.
