Micromechanical Modeling of Viscoelastic Response of GMT Composite
Authors: Megnis Modris , Varna Janis , Allen David H. , Holmberg Anders
Published: January 2017

Experimental studies have been performed to obtain creep compliance functions of polypropylene (PP) and Glass Mat reinforced Thermoplastics (GMT) with PP matrix. It was found that both GMT and PP in the considered loading region may be considered as linear viscoelastic materials. The obtained viscoelastic compliance functions were successfully used to describe material behavior in the stress relaxation test. A micromechanical model based on the correspondence principle in the Laplace domain was developed to describe the viscoelastic behavior of GMT. This model considers the GMT composite with a given fiber orientation distribution function as consisting of an infinite number of unidirectional layers with orientations corresponding to this distribution function. The viscoelastic properties of the unidirectional layer are calculated using Hashin's concentric cylinder model that uses the experimentally determined viscoelastic properties of PP matrix. The predictions for GMT have been compared with experimental data. The model predicts rather good initial properties of GMT but it gives slightly less time dependence than compared to experimental data for both relaxation functions and compliance. The cause of the difference (debonding) between matrix and fiber, nonuniform fiber spatial distribution, stress concentrations etc.) is discussed.
Viscoelastic Properties of an Epoxy Resin during Cure
Authors: O'Brien Daniel J. , Mather Patrick T. , White Scott R.
Published: January 2017

The cure dependent relaxation modulus of an epoxy resin was investigated over the entire range of cure extent. Parallel plate rheometry was used to measure the material behavior below the gel point of the epoxy network. Creep testing in three-point bend was used for specimens cured past gelation. All data were converted to the stress relaxation modulus for comparison of the material behavior among the various cure states and between the two experimental techniques. The data were used to develop a practical model for predicting the cure dependence of the relaxation modulus throughout cure under varying processing conditions.
Referring Abused Women: Does Police Assistance Decrease Abuse?
Authors: Willson Pam , McFarlane Judith , Lemmey Dorothy , Malecha Ann
Published: January 2017

To evaluate if abused women's use of the police reduced further violence experienced, 90 abused women were interviewed at a large urban police department and followed for 6 months. Frequency and severity of violence as well as danger of homicide were measured before and at 3 and 6 months after women sought police help. Women seeking police help had significantly reduced threats of abuse (F = 124.62, df = 2,81, p < .0005), actual abuse (F = 90.11, df = 2,81, p < .0005), and danger of being killed (F = 188.69, df = 2,81, p < .0005) by her intimate partner. Bonferroni post hoc tests showed that significantly fewer threats of abuse, physical abusive acts, and risk indicators for homicide had occurred from prefiling to 3 months (p < .0005) and prefiling to 6 months (p < .0005). The data indicate that referring abused women to the police is an appropriate intervention.
God in Control: Women's Perspectives on Managing HIV Infection
Authors: Woodard Elizabeth K. , Sowell Richard
Published: January 2017

Women with HIV face a number of challenges in living with this chronic, life-threatening illness: economic, physical, social, and emotional. When discussing their illness the importance these women place on having a strong spiritual life is a consistent theme. In this study, women were asked to describe and explain what spirituality meant to them, and how they used it in living with HIV. The results indicate that, in opposition to what some contemporary providers fear, HIV+ women use their spiritual life to enhance the care prescribed by providers, rather than using their faith to avoid mainstream sources of care. In addition, women related the importance of spirituality in dealing with everyday life. Knowledgeable providers can incorporate discussions of spirituality in their care of women with HIV and, in the process, potentially improve the therapeutic results of their HIV-specific care.
An Observational Study of the Development of a Nurse-Patient Relationship
Authors: Lotzkar Michelle , Bottorff Joan L.
Published: January 2017

The purpose of this exploratory descriptive case study was to identify features of nurse-patient interactions (NPI) in the development of a nurse-patient relationship (NPR). Observations of interactions in a cancer treatment unit included 60 videotaped, sequential naturally occurring NPIs involving one dyad over a 3-day period. A microanalysis of the interactions was conducted using qualitative ethological methods. The analysis focused on identifying important recurring behavioral clusters and characteristic patterns of behavior that comprised these clusters. Important features of NPIs in the development of an NPR were identified and described in detail. The active and complementary roles of both participants in this process and the contribution of social exchange, trust, and humor are highlighted. The findings illustrate the importance of continuity of nursing care if NPRs are to be used to their fullest extent to address complex patient care needs.
Counseling Hypertensive Patients: An Observational Study of 21 Public Health Nurses
Authors: Drevenhorn Eva , Håkansson Anders , Petersson Kerstin
Published: January 2017

This study observed the public health nurse's and the patient's activity level during blood pressure measurement and the kind of nonpharmacological treatment that was given. Using the Nurse Practitioner Rating Form, three structured observations were made of 21 public health nurses at their offices at health care centers. The nurses were randomly selected from 22 health care centers in Southern Sweden. The public health nurses used nonpharmacological treatment at 18 out of 63 visits, mainly diet and physical activity. The nonpharmacological conversation had a psychosocial aspect at 15 observations. During the visits, most of the facts and advice concerned somatic aspects of health promotion. Almost all patients were asked about their medication. At more than half of the observations, the nurses and the patients met at the same medium or high communication level. The nurses need training and information about nonpharmacological treatment to practice health promotion in hypertension care.
Adult Patients' Postoperative Pain Descriptions and Responses to the Short-Form McGill Pain Questionnaire
Authors: McDonald Deborah Dillon , Weiskopf Constance Spagnola
Published: January 2017

This study examined the clinical usefulness of the Short-Form McGill Pain Questionnaire (SF-MPQ). Thirty postoperative patients were asked to describe their postoperative pain and then administered the SF-MPQ. Eighteen (60%) used exact SF-MPQ sensory or affective words or synonyms to describe their postoperative pain during the interview. These results provide further evidence of the clinical relevance of the SF-MPQ sensory and affective scales. Pain descriptions by patients that go beyond pain intensity descriptions may communicate more precise information about the pain and lead to more effective pain interventions. Patients with difficulty describing their pain might be assisted by using the SF-MPQ.
An international registry of survivors with Hb Bart's hydrops fetalis syndrome
Authors: Songdej Duantida , Babbs Christian , Higgs Douglas R.
Published: January 2017

Hemoglobin (Hb) Bart's hydrops fetalis syndrome (BHFS) resulting from α0-thalassemia is considered a universally fatal disorder. However, over the last 3 decades, improvements in intrauterine interventions and perinatal intensive care have resulted in increasing numbers of BHFS survivors. We have initiated an international registry containing information on 69 patients, of which 31 are previously unpublished. In this perspective, we analyze the available clinical information to document the natural history of BHFS. In the future, once we have accrued sufficient cases, we aim to build on this study and provide information to allow counseling of at-risk couples. To date, 39 patients have survived beyond the age of 5 years, 18 of whom are now older than 10 years. Based on the available cases, we find evidence to suggest that intrauterine therapy provides benefits during the perinatal and neonatal period; however, it may not provide additional benefits to long-term growth and neurodevelopmental outcomes. Growth retardation is a major adverse long-term outcome among BHFS patients with ∼40% being severely affected in terms of weight and ∼50% in terms of height. There is also an increased risk of neurodevelopmental delay as we find 20% (11/55) of BHFS survivors suffer from a serious delay of ≥6 months. Most patients in the registry require lifelong transfusion and often have associated congenital abnormalities and comorbidities. This perspective is a first step in gathering information to allow provision of informed counseling on the predicted outcomes of affected babies.

Published: January 2017

Data on primary ciliary dyskinesia (PCD) epidemiology is scarce and published studies are characterised by low numbers. In the framework of the European Union project BESTCILIA we aimed to combine all available datasets in a retrospective international PCD cohort (iPCD Cohort).

We identified eligible datasets by performing a systematic review of published studies containing clinical information on PCD, and by contacting members of past and current European Respiratory Society Task Forces on PCD. We compared the contents of the datasets, clarified definitions and pooled them in a standardised format.

As of April 2016 the iPCD Cohort includes data on 3013 patients from 18 countries. It includes data on diagnostic evaluations, symptoms, lung function, growth and treatments. Longitudinal data are currently available for 542 patients. The extent of clinical details per patient varies between centres. More than 50% of patients have a definite PCD diagnosis based on recent guidelines. Children aged 10–19 years are the largest age group, followed by younger children (≤9 years) and young adults (20–29 years).

This is the largest observational PCD dataset available to date. It will allow us to answer pertinent questions on clinical phenotype, disease severity, prognosis and effect of treatments, and to investigate genotype–phenotype correlations.
Respiratory illness in children with disability: a serious problem?
Authors: Proesmans Marijke
Published: January 2017

Key points

Children with neurocognitive impairment often present with chronic or recurrent respiratory problems.

The respiratory problems have an important impact on quality of life and life expectancy.

The underlying causes are multiple: risk of aspiration, insufficient cough, upper airway obstruction and progressive kyphoscoliosis.

There is often a complex interplay between these known risk factors.

The diagnostic and therapeutic approach should be multidisciplinary.

Educational aims

To provide data on the prevalence of respiratory problems in children with disability and to increase awareness on this topic.

To provide insight into the complex interplay of the underlying causes and risk factors for chronic lung infection and respiratory failure.

To give an overview of the diagnostic approaches relevant in this context.

To highlight possible therapeutic approaches.

To touch on ethical considerations in this group of vulnerable and complex patients.
Medical‐grade footwear: the impact of fit and comfort
Authors: Hurst Bessie , Branthwaite Helen , Greenhalgh Andrew , Chockalingam Nachiappan
Published: January 2017

Background

Pressure‐related skin lesions on the digits are a significant cause of discomfort. Most foot pain related to ill‐fitting shoes occurs in the forefoot and digital areas. Pain has been associated with poor shoe fit, reduced toe box volume, as well as contour and shape of the shoe Off‐the‐shelf medical‐grade footwear is designed as an intervention for chronic lesions on the digits. These shoes are designed with a flexible neoprene fabric upper that is thought to reduce pressure on the forefoot and reduce discomfort associated with ill‐fitting shoes. The aim of this study was to investigate the effect of an off‐the‐shelf, medical‐grade shoe on dorsal digital pressure and perceived comfort when compared to participant's own preferred shoe.

Methods

Thirty participants (18 females, 12 males) scored their perceived comfort whilst wearing each footwear style using a visual analog comfort scale. Dorsal digital and interdigital pressures were measured in using the WalkinSense® in‐shoe pressure system. Sensors were placed on predetermined anatomical landmarks on the digits. Participants were randomly assigned the test shoe and their own shoe. Once wearing the shoe, the participants walked across a 6 m walkway and pressure data from each sensor was collected and processed to obtain peak pressure, time to peak pressure and contact time.

Results

Participants scored the test shoe with higher comfort points than their own footwear. Overall peak pressure, pressure time integral and contact time decreased, whilst the time taken to reach peak pressure increased across all anatomical landmarks whilst wearing the test shoe. Statistically significant changes were observed for all of the measured variables relating to pressure on the medial border of the first metatarsophalangeal joint.

Conclusion

The test shoe provided greater comfort and reduced the amount of pressure on the forefoot. The medical‐grade footwear therefore, is a viable alternative to custom made prescription footwear and is more suitable than a regular everyday shoe when treating digital lesions associated with pressure.
Audiometric findings with voluntary tensor tympani contraction
Authors: Wickens Brandon , Floyd Duncan , Bance Manohar
Published: January 2017

Background

Tensor tympani contraction may have a “signature” audiogram. This study demonstrates audiometric findings during voluntary tensor tympani contraction.

Methods

Five volunteers possessing the ability to voluntarily contract their tensor tympani muscles were identified and enrolled. Tensor tympani contraction was confirmed with characteristic tympanometry findings. Study subjects underwent conventional audiometry. Air conduction and bone conduction threshold testing was performed with and without voluntary tensor tympani contraction.

Main outcome measure

Changes in air conduction and bone conduction thresholds during voluntary tensor tympani contraction.

Results

Audiometric results demonstrate a low frequency mixed hearing loss resulting from tensor tympani contraction. Specifically, at 250 Hz, air conduction thresholds increased by 22 dB and bone conduction thresholds increased by 10 dB.

Conclusions

Previous research has demonstrated a low frequency conductive hearing loss in the setting of tensor tympanic contraction. This is the first study to demonstrate a low frequency mixed hearing loss associated with tensor tympani contraction. This finding may aid in the diagnosis of disorders resulting from abnormal tensor tympani function. Tensor tympani contraction should be included on the differential for low frequency mixed hearing loss.
Complete genome sequence and whole-genome phylogeny of Kosmotoga pacifica type strain SLHLJ1T from an East Pacific hydrothermal sediment
Authors: Jiang Lijing , L’Haridon Stéphane , Jebbar Mohamed , Xu Hongxiu , Alain Karine , Shao Zongze
Published: January 2017

Kosmotoga pacifica strain SLHLJ1T is a thermophilic chemoorganoheterotrophic bacterium isolated from a deep-sea hydrothermal sediment. It belongs to the physiologically homogeneous Thermotogaceae family. Here, we describe the phenotypic features of K. pacifica together with its genome sequence and annotation. The chromosome has 2,169,170 bp, organized in one contig. A total of 1897 candidate protein-encoding genes and 177 RNA genes were identified. The 16S rRNA gene sequence of this strain is distantly related to sequences of some relatives classified in the same genus (K. olearia 7.02% and K. shengliensis 7.83%), with dissimilarity percentages close to the threshold generally described for genus delineation. Nevertheless, the percentage of conserved proteins (POCP), which is much higher than 50% (around 70%), together with phenotypic features of the isolates, confirm the affiliation all Kosmotoga species described so far to the same genus.
Indian Slaves from Guiana in Seventeenth-Century Barbados
Authors: Arena Carolyn
Published: January 2017

The economy of Barbados benefited both from the labor of Indian captives and from their isolated position away from indigenous zones of conflict and economic competition. The Anglo-Barbadians accessed labor in Guiana, the region between the Orinoco and Amazon Rivers. Barbados was a secure location, away from the indigenous war zones, trade routes, and markets for captives in Guiana. In this context, the Barbadian sugar industry flourished without threat from Indians’ reprisals. Seventeenth-century ethnographies and modern scholarship have emphasized the limited nature of this Indian slave trade, or the finite roles that Indian slaves played in colonial economies. However, the archival sources I use provide evidence that colonists routinely exploited Guiana for native slaves, and once on Barbados, the latter contributed a broad range of skills to the early economy of the island.

Unwork and the Duchampian Contemporary
Authors: Barker Stephen
Published: January 2017

The implications of Bernard Stiegler's critique of the amateur are far-reaching for art, aesthetics, and critical thought. In the three lectures on aesthetics published in this special issue, Stiegler explores those implications and their relation to the amare—the loving that is etymologically at the root of the word amateur—that is required for art-work. For Stiegler, Marcel Duchamp is an exemplar of this work precisely because of his libidinal discourse with art, most evident in the readymades, referred to by Stiegler as “not a burning scandal but something like a mute surprise.” This essay reconsiders the nature of Duchamp's love affair with art as désamour, or lovelessness, in which work ceases to be work and art is “trans-formed” into “anart.” Duchamp's trajectory from the Nude Descending a Staircase, No. 2 of 1912 and the infamous Fountain of 1917, the period Stiegler addresses, is complex and worth tracking, not from 1912 but from 1910, with the transitional Bilboquet, in which the very nature of art-making is interrogated. Nothing less than the nature of art and the love of art are at the heart of this adventure. Following Duchamp's path from Bilboquet onward yields insights into both Duchamp's désoeuvrement and Stiegler's pivotal concern with the pharmakon. Duchamp is thus revealed as his own best “mute surprise,” his own most provocative artwork, and the key to his lasting contemporaneity.
Compression in Philosophy
Authors: Galloway Alexander R. , LaRivière Jason R.
Published: January 2017

This essay superimposes technical definitions of data compression onto philosophical discussions of aesthetics. Two basic approaches are addressed: abstract compression and generic compression. The first, outlined well in the work of Bernard Stiegler, concerns the classic phenomenological and metaphysical debates around expression, revealing, representation, mimesis, and the “extensions of man.” The second, rather ill-defined thus far, deals with a different set of concerns: encryption, obliteration, unilateral determination, irreversibility, and generic humanity. With the theme of compression in hand, this essay offers an alternative reading of Stiegler's aesthetic theory on the grounds that it is not yet compressive enough.
Impossible, Unprincipled, and Contingent: Bernard Stiegler's Project of Revolution and Redemption
Authors: Colebrook Claire
Published: January 2017

Bernard Stiegler's corpus is at once a diagnosis of the human organism's capacities and incapacities in relation to technè at the same time as it couples this organology with the refusal and affirmation of a properly human technological life. His work is at once destructive of any notion of human autonomy at the same time as it laments a certain automatism of the human in its captivation by the very systems that enable its ongoing life. Differing significantly from other forms of deconstruction that posit a possible future in a formal opening that is made possible by any repeatable text (such that to repeat a text is to allow for its transformation), Stiegler locates the pharmakon in a specifically inorganic relation the human bears to itself as an organism. In order to function as a relatively stable and autonomous self, the human must be open to inscriptive systems that are as incapacitating as they are enabling. This leaves the problem of the decision regarding the future as at once ungrounded while also bounded by the archive of the human species.
When social behaviour is moulded in clay: on growth and form of social insect nests
Authors: Perna Andrea , Theraulaz Guy
Published: January 2017

The nests built by social insects are among the most complex structures produced by animal groups. They reveal the social behaviour of a colony and as such they potentially allow comparative studies. However, for a long time, research on nest architecture was hindered by the lack of technical tools allowing the visualisation of their complex 3D structures and the quantification of their properties. Several techniques, developed over the years, now make it possible to study the organisation of these nests and how they are built. Here, we review present knowledge of the mechanisms of nest construction, and how nest structure affects the behaviour of individual insects and the organisation of activities within a colony.
Modification of feeding circuits in the evolution of social behavior
Authors: Fischer Eva K. , O'Connell Lauren A.
Published: January 2017

Adaptive trade-offs between foraging and social behavior intuitively explain many aspects of individual decision-making. Given the intimate connection between social behavior and feeding/foraging at the behavioral level, we propose that social behaviors are linked to foraging on a mechanistic level, and that modifications of feeding circuits are crucial in the evolution of complex social behaviors. In this Review, we first highlight the overlap between mechanisms underlying foraging and parental care and then expand this argument to consider the manipulation of feeding-related pathways in the evolution of other complex social behaviors. We include examples from diverse taxa to highlight that the independent evolution of complex social behaviors is a variation on the theme of feeding circuit modification.
Abnormal expression of ATP1A1 and ATP1A2 in breast cancer
Authors: Bogdanov Alexey , Moiseenko Fedor V. , Dubina Michael
Published: January 2017

Breast cancer is the first in incidence and the second in death among all solid tumors occurring in women. The identification of molecular genetic abnormalities in breast cancer is important to improve the results of treatment. In the present study, we analyzed microarray data of breast cancer expression profiling (NCBI GEO database, accessionGSE65194), focusing on Na+/K+-ATPase coding genes. We found overexpression of theATP1A1and down-regulation of theATP1A2. We expect that our research could help to improve the understanding of predictive and prognostic features of breast cancer.
A simple method for calculation of basic molecular properties of nutrients and their use as a criterion for a healthy diet
Authors: Veljkovic Veljko , Perovic Vladimir , Anderluh Marko , Paessler Slobodan , Veljkovic Milena , Glisic Sanja , Nicolson Garth
Published: January 2017

Background: Healthy nutrition is vital for good health and well-being. Despite the important role of a healthy nutritional diet, recommendations for healthy eating remain elusive and are mainly based on general properties of nutrients. The present study proposes an improved characterization of the molecular characteristics of nutrients, which are important for biological functions and can be useful in describing a healthy diet. Methods: We investigated the electronic properties of some known nutrient ingredients. In this analysis, we used the average quasi valence number (AQVN) and the electron-ion interaction potential (EIIP), which are molecular descriptors that represent the basic electronic properties of organic molecules.  Results: Our results show that most nutrients can be represented by specific groups of organic compounds according to their basic electronic properties, and these differ from the vast majority of known chemicals. Based on this finding, we have proposed a simple criterion for the selection of food components for healthy nutrition. Discussion: Further studies on the electronic properties of nutrients could serve as a basis for better understanding of their biological functions.
Online Shopping and Platform Design with Ex Ante Registration Requirements
Authors: Morath Florian , Münster Johannes
Published: January 2017

We study platform design in online markets in which buying involves a (nonmonetary) cost for consumers caused by privacy and security concerns. Firms decide whether to require registration at their website before consumers learn relevant product information. We derive conditions under which a monopoly seller benefits from ex ante registration requirements and demonstrate that the profitability of registration requirements is increased when taking into account the prospect of future purchases or an informational value of consumer registration to the firm. Moreover, we consider the effectiveness of discounts (store credit) as a means to influence the consumers’ registration decision. Finally, we confirm the profitability of ex ante registration requirements in the presence of price competition.

Spillover Effects Within Business Groups: The Case of Korean Chaebols
Authors: Joe Denis Yongmin , Oh Frederick Dongchuhl
Published: January 2017

We examine the spillover effects that occur within Korean business groups (i.e., chaebols) by focusing on the market reactions of event firms to announcements of credit rating changes. We find that there are positive spillovers (caused by positive market reactions) and negative spillovers (caused by negative market reactions) that are driven by the market reactions of event firms. Our analyses indicate that negative spillovers are more dominant than positive spillovers. Moreover, a spillover that is driven by a leading firm within a business group has stronger effects on other firms in the group than a spillover that is driven by a nonleading firm. This suggests that the market evaluation of a business group is conducted more on the basis of a leading firm than a nonleading firm within a group. Finally, we show that the spillover effects that are analyzed in our study are more noticeable when the business relationship between an event firm and other affiliated firms is closer.

Barriers to paramedic education in black and ethnic minority (BME) groups
Authors: Farquharson Natalie , Dudley Robert , Hardwick Sharon , Zandbeek Jennifer
Published: January 2017

Purpose:

To gain an understanding of how Black and Minority Ethnic (BME) groups respond to information about paramedic courses, their experience of the enrolment processes and their experience of paramedic training.

Methodology:

Telephone interviews were conducted with qualified paramedics and student paramedics from BME groups.

Findings:

Interviews revealed issues in relation to the accessibility and understanding of information on paramedic education and a lack of information in preparation for paramedic courses, causing unrealistic expectations. A lack of diversity in the student population, incidences of racial offence (unconscious or conscious), and a lack of visibility of BME staff in the ambulance service as well as in the wider community were identified.

Practical implications:

The results produced from this evaluation may contribute towards a series of recommendations in order to better inform practice to increase the diversity of students entering into paramedic science and in order to avoid issues such as student attrition
Zinc-Chromium oxide catalyst for gas-phase ketonisation of pentanoic acid
Authors: Al-ghamdi Mohammed , Bayahia Hossein
Published: January 2017

Oxides of Zinc and Chromium mixed catalyst with different atomic ratios of Zinc and Chromium were tested in the ketonisation of pentanoic acid in the gas phase. These catalysts were active to form 5-nonanone, at 300 – 400 oC and ambient pressure.  It found that Zn-Cr with an atomic ratio (10:1) gave the best catalytic performance in  comparison with other oxides with higher or lower atomic ratio of Zn and Cr mixed oxides, ZnO and Cr2O3. In this test, Zn-Cr (10:1) gave 82% selectivity of 5-nonanone as the main product at 86% conversion of acid at 350oC. The catalyst showed stable performance at the best selected conditions with a small decrease of acid conversion. For catalyst characterization, BET surface area and porosity technique, X-ray diffraction and DRIFTS of pyridine adsorption were used.
Integrating superdiversity in urban governance: the case of inner-city Lisbon
Authors: Oliveira Nuno , Padilla Beatriz
Published: January 2017

This paper analyses how urban governance incorporated migration-driven superdiversity combining cultural and economic development policies. We use the case of Mouraria, a Lisbon neighbourhood, as a site where city strategies accommodate old and new diversities to render a cosmopolitan sense associated to a ‘diversity advantage’ approach. We identify three strategies shaping urban governance: de-ethnicisation of superdiversity and urban growth policies, diversity aestheticisation and the rationale of encounter, and place marketing and city branding. We find that urban governance in a superdiverse neighbourhood relies on policies of economic development and market creation that incorporate cultural diversity from a de-ethnicised perspective.
NEGATIVE INTEREST RATES AND HOUSING BUBBLES
Authors: Stroukal Dominik , Kadeřábková Božena
Published: January 2017

In years after the financial crisis economists started to propose negative interest rates as away how to escape from a liquidity trap. Negative interest rate was considered to be impossible butfew countries have already set them below the lower zero bound. However, it has been done onlyin the central banks but not in the commercial banks. The main thesis of this paper is that lowinterest rates can inflate a housing bubble and as a result negative interest rates would only inflateit more. First, proposals how to make interest rate negative even in commercial banking arepresented in the paper. Then we discuss general consequences of negative interest rates such asredistribution, initiation of a business cycle and most importantly, inflation. Finally, we look at thehousing market and present theoretical and some empirical evidence of a possible ongoing bubble.The theory suggests that the negative interest rate would inflate the bubble necessarily.Consequences of a later decrease of housing prices have to be taken into account whenevernegative interest rates are proposed.
GEOTECHNICAL PROPERTIES OF LATERITIC SOIL STABILIZED WITH THE ASHES OF OIL PALM FRONDS
Authors: Nnochiri Emeka , Aderinlewo Olufikayo
Published: January 2017

This study assesses the geotechnical properties of lateritic soil stabilized with the ashes ofoil palm fronds. These properties are then compared with those of the same soil stabilized withcement to determine how well the ashes perform since cement is considered to be the beststabilizer. Laboratory tests such as specific gravity, moisture content, Atterberg limits, particle sizedistribution, compaction, unconfined compressive strength (UCS) and California bearing ratio(CBR) tests were first carried out to determine the basic properties of the lateritic soil (without thestabilizers). Based on the results of these tests, the soil was classified according to AASHTO soilclassification system as an A-7-5 soil which is a poor soil. Hence, the need for stabilization.Thereafter, strength tests such as California bearing ratio (CBR), unconfined compressive strength(UCS) and compaction tests were performed on the soil to which the ashes and cement wereadded in percentages of 2, 4, 6, 8 and 10 by weight of the lateritic soil. The compaction testshowed that the highest maximum dry densities (MDD) were recorded in the case of the oil palmfrond ash (OPFA) and cement at 4% (MDD = 2.02kg/m3) and 6% (MDD = 2.40kg/m3) respectively.The highest CBR values obtained were 32.6% and 87.32% at 4% OPFA content and 6% cementcontent respectively.The unconfined compressive strengths (UCS) of the soil were highest at 4%OPFA content (234.86kN/m2) and 6% cement content (588.32kN/m2). The chemical testsperformed on the OPFA and the cement showed that the highest oxide component were SiO2(33.67%) and CaO (60.83%) respectively.
IMPACT OF IMAGE RESOLUTION ON PAVEMENT DISTRESS DETECTION USING PICUCHA METHODOLOGY
Authors: Salini Reus , Xu Bugao , Souliman Mena
Published: January 2017

An accurate and regular survey of the road surface distresses is a key factor for pavementrehabilitation design and management, allowing public managers to maximize the value of thecontinuously limited budgets for road improvements and maintenance. Manual pavement distresssurveys are labor-intensive, expensive and unsafe for highly-trafficked highways. Over the years,automated surveys using various hardware devices have been developed and improved forpavement field data collection to solve the problems associated with manual surveys. However,the reliable distress detection software and the data analysis remain challenging. This studyfocused on the analysis of a newly-developed pavement distress classification algorithm, called thePICture Unsupervised Classification with Human Analysis (PICUCHA) method, particularly theimpact of image resolutions on its classification accuracy. The results show that a non-linearrelationship exists between the classification accuracy and the image resolution, suggesting thatimages with a resolution around 1.24 mm/pixel may provide the optimal classification accuracywhen using the PICUCHA method. The findings of this study can help to improve more effectiveuses of the specialize software for pavement distress classification, to support decision makers tochoose cameras according to their budgets and desired survey accuracy, and to evaluate howexisting cameras will perform if used with PICUCHA.

A remark on local fractional calculus and ordinary derivatives
Authors: Almeida Ricardo , Guzowska Małgorzata , Odzijewicz Tatiana
Published: January 2017

In this short note we present a new general definition of local fractional derivative, that depends on an unknown kernel. For some appropriate choices of the kernel we obtain some known cases. We establish a relation between this new concept and ordinary differentiation. Using such formula, most of the fundamental properties of the fractional derivative can be derived directly.
Group 14 metalloles condensed with heteroaromatic systems
Authors: Ohshita Joji
Published: January 2017

There has been keen interest in group 14 metalloles
as building units of conjugated organic functional
materials. This short review summarizes our recent work
on group 14 metalloles condensed with heteroaromatic
systems, including thiophene and pyridine. These condensed
metalloles show interesting properties depending
on both the group 14 metallole elements and the heteroaromatic
systems. High planarity of the condensed systems
and interaction between the element σ*-orbital and

Authors: Pereira Anderson Siqueira , Dutra-Thomé Luciana , Koller Silvia Helena
Published: January 2017

Este estudo objetivou avaliar relações entre habilidades sociais e pensamentos negativos com fatores de proteção e de risco na adultez emergente. Participaram 521 adultos entre 18 e 30 anos (M = 22,68; DP = 3,21). Os participantes foram agrupados com base em seus escores de habilidades sociais e presença de pensamentos negativos frente a interações sociais. Foram desenvolvidas ANOVAS para comparação das médias entre os grupos. Comparações de grupos demonstraram diferenças significativas entre eles, em que o grupo socialmente competente apresentou medias superiores de fatores de proteção e inferiores nos fatores de risco em relação aos demais. Habilidades sociais podem ser consideradas fator de proteção, sua presença está associada a melhores índices de autoestima, autoeficácia e qualidade nos relacionamentos.
A (im)possibilidade do “conhecimento” de Deus em Kant: o Sumo Bem, objeto necessário da razão
Authors: Rohden Luiz , De Jesus Valdinei Vicente
Published: January 2017

O sumo bem, tal qual apresentado na CRPr, consiste na união da moralidade com a felicidade. Como esta ligação não pode ser assegurada necessariamente pelo próprio homem durante a sua finita e imperfeita existência, resta que se existe uma síntese; a mesma apenas pode ser elucidada em um suposto juízo sintético a priori que possa unir a vida terrena virtuosa com a felicidade post mortem que é o que parece exigir uma síntese desta natureza (CRPr, A 215). Frente a esta questão, defendemos que há boas razões para sustentar que o sumo bem é um objeto necessário da razão prática pura com base no pressuposto metafísico da constituição peculiar da faculdade de apetição de seres racionais finitos sem comprometer, com isso, o caráter de universalidade desta pretensão. O artigo culmina apontando alguns pontos de vista de aproximação da figura do sumo bem deixando claro que não há uma prova cabal; mas a fecundidade de um conjunto de perspectivas teóricas e práticas que permitem uma série de aproximações desse conceito até o ponto em que, por razões bem fundamentadas, não parece mais razoável sustentá-lo apenas como um ideal meramente dialético.

Hashtag 0161
Authors: Rymajdo Kamila
Published: January 2017

Bugzy Malone is Manchester’s first grime artist to hit the mainstream with a UK album chart top ten entry for his 2015 debut EP Walk With Me. A career kick-started by a highly-publicized beef with London artist Chip, he has remained a controversial figure by frequently repeating the refrain ‘0161, Manny on the map’ while shunning collaboration with other local musicians. This article aims to decipher Bugzy’s rise to fame, underscoring his musical persona’s similarity to Bret Easton Ellis’s Patrick Bateman in American Psycho, to argue that the artist’s unique trajectory cemented a new individualistic era in grime culture, away from its London roots of solidarity within crews.
Revisão bibliométrica no tema Empreendedorismo Imigrante e Étnico
Authors: Cruz Eduardo Picanço , Falcão Roberto Pessoa de Queiroz
Published: January 2017

O debate sobre a imigração de milhares de refugiados para Europa e sua assimilação pela sociedade e economia locais, apresenta-se como um tema em voga na atualidade. Adicionalmente, o empreendedorismo internacional de enclave étnico tem sido estudado como uma das formas de mobilidade social e integração destes grupos. Diversas comunidades de imigrantes de várias etnias têm sido objeto de estudo, no entanto, o brasileiro imigrante tem sido pouco estudado quanto a seu perfil, cultura e comportamento empreendedor. As pesquisas bibliométricas realizadas dentro do tema de empreendedorismo imigrante e étnico, apontam para uma mudança em seu enfoque original em ‘economias de enclave’, ‘empresas étnicas’ e ‘enraizamento social’ para investigações relacionadas aos ‘empresários imigrantes’, às ‘redes de negócios imigrantes’ e aos ‘empresários transnacionais’. Este artigo pretende, portanto, apresentar o resultado de um estudo bibliométrico contemplando os trabalhos seminais, as principais teorias internacionais a respeito de empreendedorismo imigrante e de enclaves étnicos, assim como identificar lacunas da literatura brasileira e internacional, expandindo este campo de pesquisa. Como principais resultados, os autores apresentam uma análise de conceitos, teorias e artigos mais citados neste campo de pesquisa e apontam para possíveis caminhos futuros de investigação.

Authors: Camargo Mercedes Rodríguez , Solá-Martínez Tomás , Chaves-Barboza Eduardo
Published: January 2017

This paper seeks to analyse the students' perception (population; 1997; sample size: 252) in three Colombian universities regarding the administrative management of the virtual distance-learning programs in which they participate. In order to reach this objective, twelve items with a four-point Likert scale were measured regarding the administrative management. In regard to the data the following tools are used: a descriptive analysis and inferential statistics; the Pearson correlation coefficient; an analysis of variance using Wilcoxon and Kruskal-Wallis tests; and a Kaiser- Meyer-Olkin multivariate factorial analysis with Varimax rotation.The results reveal that the programs have an adequate administrative management in the process of induction, training, extension, and support to the academic work. From the students' perspective, the administrative management is improved if the right technological infrastructure is promoted with the purpose of allowing the access to administrative services and to research.
Organizational Voice Behaviour and its Investigation in Terms of Organizational Variables
Authors: Kok Sabahat Bayrak , Sarikaya Mehtap , Coban Hatice
Published: January 2017

Organizational voice described as employees’ attitude of expressing their opinions to influence organizational activities reluctantly has three varieties of “acquiescent voice” including acquiescence behaviour relying on submission; “defensive voice” including self-defence behaviour because of a certain fear; and “prosocial voice” behaviour toward others relying on cooperation; and these varieties differentiate according to the motives underneath of organizational voice. In the present study, it was investigated whether organizational voice behaviour and varieties of organizational voice behaviour significant origin of organizational change and development exhibit significant difference according to the demographical variables, or not. To that end, a survey study was conducted on the white-collar employees of the Denizli City companies ranked in the ISO 500 list. In the analysis of data collected from 202 white-collar employees, T-Test and ANOVA methods were employed. As a result of these analyses, it was revealed that organizational voice behaviour varieties displayed by employees were not significantly correlated with any demographical variable statistically.
