Cloud-aided online/offline ciphertext-policy attribute-based encryption in the standard model

Attribute-Based Encryption (ABE) is a useful encryption method that allows users to encrypt messages based on their attributes. However, the computational cost of ABE system is very high, because it often scales with the number of attributes. This makes ABE difficult to apply in practice. In this paper, we use the cloud computing technology as well as pre-computing technology to solve this problem, and introduce the cloud-aided online/offline ciphertext-policy ABE system. In this system, Private Key Generator (PKG) could per-compute intermediate keys offline before online key generation phase, encryptor could pre-compute intermediate ciphertexts offline before online encryption phase, and decryptor could call their cloud computing servers to transform the ciphertexts to the partially decrypted ciphertexts before decryption phase. This greatly reduces the local computational cost of these three phases. It is significant for mobile devices to use ABE. Then, we propose a specific scheme, and prove its adaptive security in the standard model. Finally, we introduce how to deploy our new scheme in the mobile cloud computing environment.
Consumer Environmental Attitude and Willingness to Purchase Environmentally Friendly Products: An SEM Approach

It has been found that in spite of showing concern for the environment and advocating environmentally safe activities, the Indian consumer is still not ready to accept the hard truth that it the responsibility of one and all to minimize their contribution to the overall environmental pollution. This article aims at studying socio-psychological factors which contribute in the formation of environmental attitude of consumers. It further aims at establishing the connection between environmental attitude of the consumer and his/her willingness to buy environmentally friendly products (WTB-EFPs). A conceptual model has been proposed and tested using structural equation modelling (SEM). It has been found that the dimensions, such as environmental knowledge (EK), perceived seriousness of environmental (PSE) problem, interpersonal influence (IPI), collectivism and long-term orientation (LTO), have positive relationship with consumer environmental attitude (CEA). It has also been observed that consumer with favourable environmental attitude expresses their WTB-EFPs. This is an original study conducted for the first time in India using five antecedents of CEA with the application of SEM. No demographic factors have been studied in this article in order to put more focus on their socio-psychological dimensions.
IGSPICE Simulation of Induction Machines with Saturable Inductances

A novel approach to the dynamic analysis of induction machines with saturable inductances is presented. The machine dynamics are represented by a set of nonlinear time-varying differential equations. The machine parameters (i.e. saturable inductances) are modeled by closed-form nonlinear functions. The equations which define the machine operation are modeled by d and q equivalent circuits. The equivalent circuits are simulated using the IGSPICE software package. >
Overcoming Challenges to Struvite Recovery from Anaerobically Digested Dairy Manure

Recovering struvite from dairy manure has consistently posed problems for researchers. This study separated solids from anaerobically digested dairy manure using a filtration system. Filtrate was rich in free magnesium (160 to 423 mg/L), ammonium (320 to 1800 mg N/L) and orthophosphate (93 to 332 mg P/L). High concentrations of free calcium (128 to 361 mg/L) and alkalinity (3309 to 6567 mg/L as CaCO3), however, may hinder struvite precipitation. Batch precipitation tests were conducted to identify and overcome factors that interfere with struvite formation. Precipitation tests at pH 9 identified calcium and ionic strength as most probable interferences. Calcium addition did not significantly change phosphorus removal efficiency, but decreased struvite purity because of formation of calcium phosphates when Ca:P activity ratio was greater than 0.5 to 1. Batch tests demonstrated effective calcium removal from anaerobically digested dairy manure through precipitation of calcium carbonate at pH 9 to 10 while retaining magnesium and orthophosphate, lessening hindrance to struvite formation.
Pure-transvaginal natural orifice transluminal endoscopic surgery (NOTES) ovariohysterectomy in bitches: a preliminary feasibility study

Natural orifice transluminal endoscopic surgery (NOTES) is a relatively new surgical access for minimally invasive surgery, which is being widely studied in human medicine. However, few studies focusing on its applicability in the small animal practice have been performed so far. The aim of the current study was to evaluate the feasibility of pure-NOTES transvaginal ovariohysterectomy in bitches. Five bitches were evaluated. The abdomen was accessed through an 11mm trocar inserted through a vaginal incision. Using a rigid endoscope with working channel, the ovarian pedicles were coagulated and sectioned using bipolar diathermy. The uterine horn was pulled into the trocar and exteriorized along with the cannula. The uterine body and vessels were coagulated or ligated. The uterine stump was replaced into the abdominal cavity and the pneumoperitoneum drained. Pure-NOTES OHE was successfully accomplished in four out of five bitches. In the first try, it was converted to a hybrid-NOTES technique due to instrument failure. Mean surgical time was 52.1 (SD±11.5 minutes) for the pure-NOTES technique. Pure-NOTES OHE is feasible in bitches, which may result in no major complications and excellent surgical recovery.
New Trends and Issues Proceedings on Humanities and Social Sciences

While the ubiquity and usage of Mobile Instant Messaging (MIM) applications such as WhatsApp has recorded unprecedented growth, their role for teaching and learning remains unclear. To address this gap, this paper systematically reviews empirical studies by examining the educational effects, designs, tools and settings of MIM. For this purpose the databases of PsycINFO, ERIC, Ovid MEDLINE, Web of Science and Google Scholar were systematically searched. Thematic analysis was adopted to analyze and synthesize qualitative data. Findings suggest that MIM is primarily used as group learning platform to enhance pre-existing education formats in a wide range of subjects. The use of MIM in education settings augments the transactional roles of students and requires learners and educators to balance the social and cognitive dimensions of interactional engagement.
VGLUT 1 / VGAT CO-EXPRESSION SUSTAINS GLUTAMATE-GABA CO-RELEASE AND IS REGULATED BY ACTIVITY

In adult neocortex, VGLUT1, the main glutamate vesicular transporter, and VGAT, the GABA vesicular transporter, are co-expressed in a subset of axon terminals forming both symmetric and asymmetric synapses, where they are sorted to the same vesicles. However, the functional consequence of this co-localization in cortical neurons has not been clarified. Here, we tested the hypothesis that cortical axon terminals co-expressing VGLUT1 and VGAT can evoke simultaneously monosynaptic glutamate and GABA responses and investigated whether the amount of terminals co-expressing VGLUT1 and VGAT is affected by perturbations of excitation-inhibition balance. In rat primary cortical neurons, we found that a proportion of synaptic and autaptic responses were indeed sensitive to consecutive application of selective glutamate and GABAA receptor blockers. These “mixed” synapses exhibited paired-pulse depression. Notably, reducing the activity of the neuronal network by glutamate receptor antagonists decreased the amount of “mixed” synapses, whereas reducing spontaneous inhibition by bicuculline increased them. These synapses may contribute to homeostatic regulation of excitation/inhibition balance.
Perceptions regarding the use of physical restraints with elderly persons: comparison of Israeli health care nurses and social workers

In view of the difficulty involved in decision-making regarding the use or removal of physical restraints and the recent pattern encouraging the use of interdisciplinary teams for elder care issues, the present study compared the perceptions of Israeli nurses and social workers in health care settings regarding the use of physical restraints. Data were collected from a convenience sample of 50 nurses and 69 social workers working in long-term and acute care settings. The findings indicated that participants in all professions attributed moderate to low importance towards the use of physical restraints. Social workers' perceptions were similar to those of nurses in psychiatric hospitals and slightly more favourable to the use of physical restraints than those of nurses in nursing homes. Patients' safety (as reflected in the scores of the items related to protecting an older person from falling and protecting an older person from pulling out a catheter) was the most important reason for using physical restraints for both groups. Increased attention should be given to the role of social workers as team members in the process of decision-making regarding the use or removal of physical restraints, especially as mediators between the elderly person, family members and staff members.
Adult Nestin‐expressing Subependymal Cells Differentiate to Astrocytes in Response to Brain Injury

The adult brain contains a small population of central nervous system (CNS) cells in the subependyma which, like embryonic CNS progenitor cells, express the intermediate filament nestin. In this report, the differentiation capacity in vivo of these cells was analysed following a standardized trauma. Before the trauma, the subependymal cells expressed nestin but not the astrocytic and neuronal differentiation markers glial fibrillary acidic protein (GFAP) and neurofilament respectively. In response to injury, the majority of the subependymal cells coexpressed nestin and GFAP, but never nestin and neurofilament. Furthermore, cells coexpressing nestin and GFAP were found progressively further away from the subependyma and closer to the lesion at later time points after the injury, indicating that these cells migrate towards the lesion. Nestin was in addition re‐expressed in reactive astrocytes near the lesion and in non‐reactive astrocytes very far from the lesion throughout the ipsilateral cortex. In conclusion, our data indicate that the nestin‐positive subependymal cells are an in vivo source for the generation of new astrocytes but not neurons after injury, and that nestin re‐expression in astrocytes following traumatic stimuli can be used as a sensitive marker for astroglial activation.
Subjective wellbeing in psychosis: Mediating effects of psychological distress on happiness levels amongst individuals diagnosed with paranoid schizophrenia

A correlational study examined the suppositions of Headey and Wearing’s four-dimension model of subjective wellbeing (SWB) and psychological distress amongst people experiencing psychosis. The research objective was to replicate the model with the studied sample and to examine how emotional distress resulting from psychosis affects the individuals’ satisfaction with life and positive affect levels. Forty-seven individuals with a diagnosis of paranoid schizophrenia completed self-report measures of psychoticism, paranoid ideation, depression and anxiety (Brief Symptom Inventory), positive affect (Affect Balance Scale), and life satisfaction (Satisfaction With Life Scale). Correlational patterns of the four-dimension model were replicated with individuals experiencing psychosis. Although the levels of depression and anxiety were clearly elevated in comparison with general population norms, the levels of positive affect remained similar to those in the general population, and the average life satisfaction appeared only slightly decreased. Depression was found to act as a dominant mediator between the severity of experiences of psychosis and satisfaction with life. Possible explanations for the findings are proposed and implications from the positive clinical psychology perspective are suggested. Based on the study outcomes it is argued that: (1) psychosis does not equal unhappiness, (2) psychosis does not immobilize adaptive mechanisms of SWB, (3) psychosis does not exempt individuals from positive mood set-points, and (4) psychosis does not indiscriminately lower life satisfaction.
GROSS MUSCULAR ANATOMY OF LIMULUS POLYPHEMUS (XIPHOSURA, CHELICERATA) AND ITS BEARING ON EVOLUTION IN THE ARACHNIDA

Abstract Due to their widespread use as model systems and their reputation as living fossils, horseshoe crabs (Xiphosura) have been studied intensively by physiologists and paleontologists. The close phylogenetic relationship between horseshoe crabs and arachnids might also have been expected to inspire studies of xiphosurans by comparative arachnologists, but surprisingly few have been undertaken. Here, the first exhaustive survey of muscular anatomy of the Atlantic horseshoe crab is conducted as part of an on-going study of the evolutionary morphology and phylogeny of arachnids. Dissections of adult and immature individuals established 113 muscle groups comprising over 750 individual muscles, with several being recognized or correctly described for the first time. New insights into skeletomuscular evolution and phylogeny of arachnids were derived primarily from the axial muscle system. Specifically, it is argued that Limulus retains a box-truss axial muscle system like that of plesiomorphic members of other arthropod groups, that this is also a plesiomorphic condition for Chelicerata, and that arachnids are united by the loss of one component of this system, the anterior oblique muscles. Combined with comparative morphological and molecular evidence from previous studies, this study adds greater weight to the widely held view that, among extant chelicerates, Xiphosura and Arachnida are monophyletic sister groups and counters recent speculation that scorpions are more closely related to xiphosurans than to spiders, whipscorpions and other arachnids.
Prenatal exclusion of stickler syndrome

Stickler syndrome is an autosomal dominant disorder of the connective tissue which includes ocular and systemic manifestations. We report on a large kindred in which we were able to demonstrate very tight linkage between the disease and the type II collagen gene (COL2A1) (LOD score 3·91 at θ=0). In a family in which the father and one of his daughters were severely affected, DNA analysis from a chorionic villus sample demonstrated that the fetus possessed the normal allele of COL2A1. Thereafter a normal child was born.
Cyclical Dispersion in Expected Defaults

A growing literature shows that credit indicators forecast aggregate real outcomes. While researchers have proposed various explanations, the economic mechanism behind these results remains an open question. In this paper, we show that a simple, frictionless model explains empirical findings commonly attributed to credit cycles. Our key assumption is that firms have heterogeneous exposures to underlying economy-wide shocks. This leads to endogenous dispersion in credit quality that varies over time and predicts future excess returns and real outcomes.Received August 7, 2017; editorial decision June 26, 2018 by Editor Stijn Van Nieuwerburgh.

Ultrasound Evaluation of Diaphragm Force Reserve in Patients with Chronic Obstructive Pulmonary Disease.

RATIONALE Diaphragm function is a key determinant of dyspnea in COPD; however, it is rarely assessed in clinical practice. Lung hyperinflation can also impair diaphragm function. Ultrasound can assess the activity, function and the force reserve of the diaphragm. OBJECTIVES To compare diaphragm activity, function, and force reserve among patients with COPD and in healthy controls. METHODS 80 patients with stable COPD and 20 healthy controls were enrolled (97% of them were male). Ultrasound was used to measure the thickening fraction of the diaphragm during tidal breathing and maximum volitional effort. Outcome measures were: 1) the difference in diaphragm force reserve, activity, and function between COPD patients and controls, 2) the correlation between lung volumes and diaphragm force reserve, activity, and function, and 3) the relationship between diaphragm force reserve and the rate of moderate to severe exacerbation of COPD. RESULTS The tidal thickening fraction of the diaphragm during resting breathing (TFdi-tidal) was higher in COPD patients than in controls (P = 0.002); it was approximately twice as high in patients with severe COPD than in controls. Patients with COPD had poorer diaphragm function than controls as assessed by the maximal thickening fraction of the diaphragm (TFdi-max) during Muller maneuver (P < 0.01). Diaphragm force reserve ratio assessed by 1 - (TFdi-tidal/TFdi-max) was lower in COPD patients than in controls and it fell with increasing GOLD stages (P < 0.001); it correlated with inspiratory capacity (r = 0.46) and the BODE index, a multidimensional scoring system (r = -0.49). Patients who developed exacerbation during the following two years had less force reserve than patients without exacerbation (P = 0.024). CONCLUSIONS Male patients with COPD have increased diaphragm workload, impaired diaphragm function, and reduced force reserve compared to healthy subjects. Ultrasound assessment of the diaphragm in COPD provides important functional information. Clinical trial registered with Thai Clinical Trials Registry (#TCTR20160411001).
Unitriangular Factorization of Twisted Chevalley Groups

Unitriangular factorization is a presentation of a linear group as a product of unipotent radicals of a Borel subgroup and its opposite. Whether this decomposition is known for Chevalley groups over rings of stable rank 1 and some Dedekind rings of arithmetic type, the case of twisted groups has been studied only over finite fields. In the present paper we give a much simpler proof for twisted groups over finite fields and the field of complex numbers.
The Impact of Policy Changes on Milk and Beverage Consumption of Texas WIC Children

Major changes in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) food packages that were implemented in 2009 included reductions in the amount of milk and 100% juices, as well as the removal of whole milk from food packages. In analyzing the effect of these changes on the beverage consumption of Texas WIC children ages two to four, we found a significant decrease in the amount of whole milk consumed, and this decrease was partially offset by the increase in the amount of lower-fat milks consumed. Intakes of both desirable and undesirable nutrients from milk were decreased.
Adult Survival and Movement in Males of the Damselfly Hetaerina cruentata (Odonata: Calopterygidae)

During a mark-recapture study of the territorial damselfly Hetaerina cruentata (Rambur), several changes in population size, survivorship and birth rates occurred, probably caused by physical conditions and a natural seasonal decline in population size. The average survival rate of males (expected value per day = 0.978) was the highest reported for the Calopterygidae and possibly all Odonata. This value could have been affected by factors that reduced energy expenditures at the end of the season. Analysis of male dispersion showed aggregated distributions, which are expected for territorial species. While most males dispersed, no age-class showed a tendency to move upstream or downstream. Adult females were rare; however, the sex ratio of nymphs was not significantly different from one.
Delivery of Multiple Epitopes by Recombinant Detoxified Adenylate Cyclase of Bordetella pertussisInduces Protective Antiviral Immunity

ABSTRACT CyaA, the adenylate cyclase toxin from Bordetella pertussis, can deliver its N-terminal catalytic domain into the cytosol of a large number of eukaryotic cells and particularly into professional antigen-presenting cells. We have previously identified within the primary structure of CyaA several permissive sites at which insertion of peptides does not alter the ability of the toxin to enter cells. This property has been exploited to design recombinant CyaA toxoids capable of delivering major histocompatibility complex (MHC) class I-restricted CD8+ T-cell epitopes into antigen-presenting cells and to induce specific CD8+cytotoxic T-lymphocyte (CTL) responses in vivo. Here we have explored the capacity of the CyaA vector carrying several different CD8+ T-cell epitopes to prime multiple CTL responses. The model vaccine consisted of a polyepitope made of three CTL epitopes from lymphocytic choriomeningitis virus (LCMV), the V3 region of human immunodeficiency virus gp120, and chicken ovalbumin, inserted at three different sites of the catalytic domain of genetically detoxified CyaA. Each of these epitopes was processed on delivery by CyaA and presented in vitro to specific T-cell hybridomas. Immunization of mice by CyaA toxoids carrying the polyepitope lead to the induction of specific CTL responses for each of the three epitopes, as well as to protection against a lethal viral challenge. Moreover, mice primed against the vector by mock CyaA or a recombinant toxoid were still able to develop strong CTL responses after subsequent immunization with a recombinant CyaA carrying a foreign CD8+ CTL epitope. These results highlight the potency of the adenylate cyclase vector for induction of protective CTL responses with multiple specificity and/or broad MHC restriction.
The impact of financial and non-financial disclosure on corporate reputation among non-professional stakeholders

This paper examines the impact of corporate social responsibility (CSR) disclosure on corporate reputation as perceived by non-professional stakeholders. Proponents of CSR disclosure argue that CSR disclosure can be considered as a tool for reputation management. We empirically investigate this claim using a reputation index which tracks the general public’s perceptions of corporate reputation over time. In our analysis, we focus on disclosure in stand-alone CSR reports and control for CSR performance. We find that, in contrast to the common belief, stand-alone CSR reports do not influence corporate reputation among non-professional stakeholders. However, we are able to document that stand-alone CSR reports influence corporate reputation among professional stakeholders. We also provide some evidence that transparent CSR disclosure on corporate websites can influence corporate reputation among non-professional stakeholders.
