Efficient Privacy-Preserving Building Blocks in Cloud Environments under Multiple Keys

With the rapid growth of big data, clients lack in storage and computational resources tend to outsource their data and computation tasks to cloud service providers. Due to concerns of privacy leakage in cloud, data owners encrypt the data via their own keys before outsourcing. However, it’s rather difficult for cloud servers to perform computations over those encrypted data, since most of existing solutions are restricted to single key setting and may reveal the final output to adversary. In this paper, we propose two sets of privacy-preserving building blocks to support outsourced computation. Specifically, these schemes allow the cloud servers to evaluate basic arithmetic functions including addition, multiplication, and exponentiation over ciphertexts under different keys by utilizing the property of proxy re-encryption technique to transform ciphertexts. They are proven to be secure in the semi-honest model and secure against eavesdropping attacks. Experimental results on local testbed and real cloud environment demonstrate that the proposed solutions achieve great performance improvements with low overhead on data owners.
Physical Disability, Discrimination, and Public Subsidies : Evidence from a Field Experiment Controlling for Workplace Accessibility

We investigate the effectiveness of government sponsored wage subsidies in mitigating labor market discrimination facing persons with physical disabilities using a large scale field experiment. Applications were randomly sent to 1477 private firms posting vacancies across the province of Québec (Canada). Applications vary disclosure of a disability (wheelchair users) and availability of a government sponsored wage subsidy. We find that average callback rates of non-disabled and disabled applicants are respectively 14.4% and 7.2%. We find that mentioning eligibility to a government subsidy does not increase callback rates. Results are robust to controls for accessibility constraints that apply to wheelchair users. Finally, We show how callback rate diffentials can be used to estimate the lower bound of the proportion of discriminating firms. Our estimates suggests at least 49.7% of firms discriminate.

Frozen Shoulder-Comparsion of Physiotherapy Alone And Along With Subacromial or Combined Subacromial and Intraarticular Steroid Injections

Introduction: Symptomatic improvement after sub-acromial steroid injections, in the initial part of treatment, has led us to conduct this study that compares the effects of physiotherapy alone, and combined with subacromial injection and also combined with both intra-articular and sub-acromial steroid injections for primary frozen shoulder. Material and Method: 75 patients with primary frozen shoulder were randomly divided into 3 groups: group 1 for physiotherapy only, group 2 for the sub-acromial injections followed by physiotherapy and group 3 for sub-acromial and intra-articular injections followed by physiotherapy. Patients were evaluated using a visual analog scale for pain, Constant score, range of motion and American Shoulder and Elbow Surgeons Score at 3, 6 and 12 weeks after starting treatment. Results: There was significant improvement in all parameters in Group 2 and 3 at 3 & 6 weeks. There was no difference between the groups at 12 weeks follow up. Group 2 and 3 were similar in outcomes at all follow ups. Conclusion: Steroid injections followed by physiotherapy were superior to physiotherapy alone for patients with primary frozen shoulder as they led to earlier pain relief. Steroid injection combined with physiotherapy is an alternative modality for treatment of primary frozen shoulder.

Mental Health Clinical Assessment of Persons With Mental Retardation and Developmental Disabilities: History

D iagnosis is the key to treatment and history is the key to diagnosis. In all fields of medicine, in fact in all fields of human services, only the history of how a problem evolved will reveal the nature of that problem. Knowing that a patient has, for example, hallucinations tells us nothing except where to start looking for a diagnosis. Only a history that reveals the slow, insidious loss of affect, interest and social judgment, or the disruption of sleep and appetite and onset of deep sadness and suicidal thoughts, or the onset of sleeplessness, overactivity, and grandiosity, will distinguish the source of the hallucinations in an episode, respectively, of Schizophrenia, Major Depressive Disorder, or Bipolar Disorder. The gathering of a history is a basic skill taught in the early years of medical school, with each specialty adding its list of things to look for and ask about. Psychiatry is no exception. Without a good history, the mental health clinician cannot easily make a diagnosis, because diagnosis relies on knowing the course and context within which the symptoms developed. This is especially true for the patient with mental retardation or developmental disability (MR/DD). Standard textbooks of psychiatry assume that the history will be obtained from the patient, perhaps supplemented by a review of past hospital records if they exist. Diagnosis usually 10
Progressive Multifocal Leukoencephalopathy in the Setting of Immune Reconstitution Syndrome: A Case Report and Review of the Literature

JC virus-associated progressive multifocal leukoencephalopathy (PML) continues to be an important cause of opportunistic infections in patients infected with human immunodeficiency virus (HIV). Here, we report a case of a 25-year-old man with a 2-year history of untreated HIV infection who presented with left hand weakness. After the initiation of highly active retroviral therapy, his viral load decreased, but his left-sided neurologic symptoms worsened. Findings from magnetic resonance imaging were consistent with PML, but no JC virus was detected in the central nervous system. The patient underwent brain biopsy, which revealed JC virus infection and changes associated with PML. This case illustrates the histopathologic findings in PML-immune reconstitution inflammatory syndrome, the phenomenon of paradoxical worsening of PML after initiation of HIV antiretroviral therapy, and highlights the limitations of JC virus detection in the cerebrospinal fluid for diagnosis.
Teachers' Work and Professionalization: The promised land or dream denied?

The goal of this article is to discuss the process of teachers’ professionalization, debating the risks of the neo-liberal discourse on professionalization in the context of conservative educational reform, particularly in Brazil. Teachers’ professionalization is understood as a process immersed in unequal relations of race, gender, and social class. In this sense, it is closely related to process of proletarianization, feminization, and racial democracy. Alongside the aspects above mentioned is also considered the relations between teachers’ professionalization and globalization of the market based on neo-liberal economic model in order to understand clearly what teachers are currently experiencing in their labor process in terms of pedagogical autonomy and control.
Lifestyle and Employees ’ Health-A Critical Review

This study critically examines the correlate between lifestyle and workers health. Specific habits such as smoking, drugs and alcohol abuse, unhealthy dietary, football fanaticism and their connection to workers health was central in our discussion. The study argues that these habits are importantly responsible for a great number of health issues and high mortality rate among workers in the past two decades. We posit that, underscoring these habits as in the past has and will continue to spell doom on workers’ health and productivity. The paper however did not undermine other causal factors of health challenges among workers but posit that a combination of strategies that addresses working conditions, insurance policies, safety regulations with “proper workers’ lifestyle” will be a panacea for healthy living and greater productivity among employees in both developed and developing countries. We therefore recommended among others policy options that encourages proper lifestyle sensitization programmes among workers.

*These authors contributed equally to this work Background: Nipple-sparing mastectomy (NSM) is becoming increasingly accepted as a treatment for breast disease; however, nipple-areolar complex (NAC) necrosis, a frequent severe postoperative complication, inhibits the popularity of this procedure. This study reports the technical aspects and short-term postoperative outcomes of NSM. Methods: A single-center, retrospective review of 110 patients treated with NSM at our institution from November 2015 to September 2018 was performed. The primary outcome was the incidence of NAC necrosis. Results: A total of 130 NSMs performed on 110 patients were included in our study. Median patient age was 42 years. We performed a sharp dissection by using a scalpel, raising 3–5 mm thick flaps, and continuing onto the undersurface of the NAC. None of the 110 patients appeared to have NAC necrosis or mastectomy skin flap necrosis. However, discoloration or ischemia of the NAC with eschar formation presented between postoperative days 3 and 7 in six nipples; four nipples were ischemic, and two were discolored. No infection was detected in any of the 110 patients. All NACs were intact after an average follow-up of 30 months, and no local or systemic recurrence was detected in those breast cancer cases. Conclusion: NSM can be safely performed in properly selected patients. Nipple necrosis was avoided using a special surgical technique, and other complications occurred at an acceptable rate.
The Information Content in the Term Structure of Commodity Prices

In this paper, we investigate the term structure of agricultural commodity prices. Using corn as an example, we demonstrate that commodity futures price curve can be wellapproximated by three latent factors: level, slope, and curvature obtained from a dynamic latent factor model. Relating the three unobserved factors to observable economic fundamentals, we find that real economic activity and relative scarcity of the commodity play an important role in the evolution of the corn futures price curve. Using Granger causality tests, we find that all three unobserved factors of the futures price curve contain predictive information on real economic activity and the relative scarcity of the commodity. Consistent with the theory of storage, there is a forwardlooking element embedded in the term structure of commodity prices that contain information regarding subsequent market fundamentals.
DNN-based Distributed Multichannel Mask Estimation for Speech Enhancement in Microphone Arrays

Multichannel processing is widely used for speech enhancement but several limitations appear when trying to deploy these solutions in the real world. Distributed sensor arrays that consider several devices with a few microphones is a viable solution which allows for exploiting the multiple devices equipped with microphones that we are using in our everyday life. In this context, we propose to extend the distributed adaptive node-specific signal estimation approach to a neural network framework. At each node, a local filtering is performed to send one signal to the other nodes where a mask is estimated by a neural network in order to compute a global multichannel Wiener filter. In an array of two nodes, we show that this additional signal can be leveraged to predict the masks and leads to better speech enhancement performance than when the mask estimation relies only on the local signals.
Transfusion of Stored Red Blood Cells in Critical Illness: Impact on Tissue Oxygenation

Blood transfusion is a common requirement in the intensive care setting. Improved tissue oxygenation is the therapeutic objective of transfusion for normovolaemic anaemia. However, the efficiency with which red blood cells (RBCs) carry oxygen to the tissues has been questioned, particularly after prolonged storage. We measured the impact on oxygen transport variables (base excess, lactate and ScvO2) of transfusion of a unit of stored RBCs in 45 critically ill adults. There were no significant changes in these variables, except for ScvO2, which increased with older units (≥ 20 days storage), suggesting impaired oxygen uptake by the tissues. The role of the storage lesion (structural and functional changes in the RBC acquired in storage media) is discussed with reference to its impact on oxygen delivery.
Rethinking Grounding 0

The grounding problem is, generally speaking, the problem of how to embed an artificial agent into its environment such that its behaviour, as well as the mechanisms, representations, etc. underlying it, can be intrinsic and meaningful to the agent itself, rather than dependent on an external designer or observer. This paper briefly reviews Searle’s and Harnad’s analyses of the grounding problem, and then evaluates cognitivist and enactive approaches to overcoming it. It is argued that, although these two categories of approaches differ in their nature and the problems they have to face, both, so far, fall short of solving the grounding problem for similar reasons. Further it is concluded that the reason the problem is still somewhat underestimated lies in the fact that modern situated and embodied AI, despite its emphasis of agent-environment interaction, still fails to fully acknowledge the historically rooted integrated nature of living organisms and their environmental embedding.
Running head: EROTIC TARGET IDENTITY INVERSIONS

Background: Erotic target identity inversions (ETII) are poorly studied paraphilias which involve sexual arousal by the idea or fantasy of being the object of one’s sexual desires. Aim: To conduct a large non-clinical online survey to investigate self-reported sexual arousal, behavioral expression, and psychological correlates of four proposed ETIIs. Methods: A total of 736 natal males and 549 natal females responded to items about selfreported sexual arousal to the idea of acting as an animal (autoanthropomorphozoophilia), idea of acting as a child or infant (autonepiophilia), natal males reporting arousal to the idea of acting as a woman (autogynephilia), and natal females reporting arousal to the idea of acting as a man (autoandrophilia). Data pertaining to sexual orientation, childhood gender nonconformity, gender identity discomfort, autism, masochism, and humiliation were also collected. Outcomes: The main outcome was a measure of selfreported arousal and expression of the ETIIs being explored using four items: arousal level (-3-3) when imagining being the erotic target exemplar; frequency of engagement in dressing or behaving like their preferred target (0-4); strength of feeling that they would be better off as the target (0-4); and the frequency of consideration of making physical changes to look or function more like the target (0-4). Results: Mild levels of reported sexual arousal to the idea of being the preferred erotic target was common among the four groups, characterizing about half of them. Gender identity discomfort was associated with autogynephilia, autoandrophilia, and autoanthropomorphozoophilia. Greater gender nonconformity was associated with autogynephilia, autoandrophilia, and autonepiophilia. Autism scores were associated with EROTIC TARGET IDENTITY INVERSIONS 3 autoandrophilia and autonepiophilia. Masochism was not associated with ETII scores, but
Do Birds of a Feather Flock Together? The Personality Traits of Administrative and Political Elites in Municipal Denmark

The recent increased interest in behavioral public administration has brought with it a plethora of concept imported from psychology. Personality is such a concept an emerging literature suggest that personality has a host of consequences for how politicians and administrative elites behave. However, we only have few studies which systematically examine how the personalities elected and administrative elites are distributed on the Big Five personality dimensions. We fill this hole in the literature by presenting a comparison of municipal top civil servants’ (n =530, 31 % response rate) and politicians’ (n = 1200, 50% response rate) personality traits as measured by a pre-validated 30-item big five instrument (Wellnitz et al., Forthcoming; Soto and John, 2016). We find some similarity between the samples, as extraversion, agreeableness, open-mindedness and conscientiousness are truncated towards the high end of the scale for both groups, and negative emotionality towards the lower end of the scale for both groups. However, we find significant differences between politicians and bureaucrats in all five traits: Bureaucrats show higher openness and extraversion, and politicians show higher conscientiousness, agreeableness and negative emotionality. Furthermore, we explore the differences between mayors and politicians, and municipal directors and managers. Mayors are less open and more emotionally stable than regular city councilors, and no differences between directors and managers are found. Implications for representativeness, management, and the relations between politicians and administrators are discussed.

Behavioral and Psychiatric Disorders in Children and Adolescents With Down Syndrome

children with intellectual disability (ID) have more behavioral and psychiatric problems than children without a developmental disability. The public often has a mythical image of children with Down syndrome (DS). Articles in peer-reviewed journals typically describe children with DS as “cheerful, happy, and sociable. ” 54 Some children with DS, however, do suffer from psychopathology, though the rates are less than their counterparts with other developmental disabilities. This paper will cover the behavioral 22
PERFORMANCE OF TASKS WITH HIGH DEMANDS OF ANTICIPATION AND CONCENTRATION UNDER VARIOUS CONDITIONS OF PHYSICAL EXERTION

Introduction Research on the impact of physical exertion on performance of cognitive tasks requiring concentration, decisionmaking and anticipation has produced conflicting results. Whilst some studies found that steady-paced aerobic exercise improved subjects’ decision-making and problemsolving ability, other studies reported no impact on cognitive performance following exercise. This unequivocal situation is possibly due to inconsistent designs and procedures employed. Research findings and anecdotal evidence suggest that moderate aerobic exercise may bring about positive impact on performance of cognitive tasks but that effect appears to diminish following high intensity exercise. The implications of this phenomenon to sport are particularly relevant to those in which decision-making and anticipation is paramount. This study aimed to investigate the effects of physical exertion on concentration and anticipation, and heart rate response during performance of cognitive tasks. Methods Twenty physically active adults volunteered to participate in this study. Their mean age, height and weight were: 22.63 61617; 1.66 yrs, 179.63 61617; 3.41 cm and 76.38 61617; 3.90 kg respectively. Participants performed the Stroop colour-word test to measure concentration, and the Bassin Anticipation Timer to measure anticipation, under three conditions: rest, moderate and high intensity physical exertion. An incremental protocol on a cycle ergometre was used to induce the different levels of physical exertion which were estimated by both heart rate reserve (HRR) and rating of perceived exertion (RPE). Participants were required to perform the tasks from a sitting position on a cycle ergometer and to maintain the cycling cadence during performance. Testing conditions were counterbalanced. Results Repeated Measures ANOVA indicted no significant differences on performance of the Stroop test or the coincidence anticipation under the three experimental conditions (rest, 50% and 80% of Maximal HRR). The results of the paired t-tests indicated that there was a significant difference (T (17) = 4.546, p =. 000) in heart rate before and during performance of the anticipation task (81.7bpm and 75.2bpm respectively). However, the difference in heart rate before and during performance of the Stroop test was not significant (82.39bpm and 79.94bpm respectively). Discussion The findings of this study indicated that physical exertion has limited impact on performance of tasks with high demands on concentration and anticipation. However, performing cognitive tasks appear to cause lowering of heart rate. This may have been caused by focus of attention on the task which in turn impacted on the parasympathetic nervous system taking over. The findings also suggest that the nature of the task being performed may determine the extent of the adverse impact of physical exertion on performance. Further research on cognitive motor skills is needed to develop an understanding of how exercise affects performance.
