Experimental measurement of the porosity and the viscous tortuosity of rigid porous material in low frequency
Authors: Sadouki M
Published: February 2018

In this paper, an acoustic method is presented for measuring the porosity and the viscous tortuosity of air-saturated-porous materials at low frequencies. The proposed method is based on a temporal model of the direct and inverse problem for the reflection of low-frequency waves by homogeneous isotropic slab of porous material having a rigid frame. Reflected coefficient for a slab of porous material is derived from the responses of the medium to an incident acoustic pulse where a simple relation between flow resistivity, porosity, viscous tortuosity and the reflected waves is obtained. A numerical method and efficient tool for the estimation of the porosity and the viscous tortuosity are presented and discussed.
Effect of integrated ride and cornering dynamics of a military vehicle on the weapon responses
Authors: Banerjee Saayan , Balamurugan Varadarajan , Krishna Kumar R
Published: February 2018

The present study brings out the influence of a non-linear dynamics model of military vehicle with trailing arm suspension, on the weapon dynamics responses. A 20 degrees of freedom integrated ride and cornering dynamics model has sequentially been coupled with the 7 degrees of freedom weapon dynamics model. The 20 degrees of freedom integrated model includes the bounce, pitch, roll, longitudinal, lateral and yaw motions of the sprung mass and rotational dynamics of the 14 unsprung masses. The 7 degrees of freedom weapon model comprises the coupled elevation and azimuth dynamics. The coupled weapon model includes angular rotation of the elevation drive, breech and muzzle in elevation direction, as well as, angular rotation of the azimuth drive, turret, breech and muzzle in azimuth direction. The actual physical behaviour of each of the hydro-gas trailing arm suspension units is implemented in the governing differential equations. The non-linear governing equations also incorporate the dynamic coupling between each of the axle arms and sprung mass, which is an inherent behaviour of the trailing arm suspension, unlike their equivalent vertical representation. The integrated model has been simulated for different cornering manoeuvres at specified speeds. It is observed that the sprung mass dynamics, emanating from different manoeuvres, significantly affects the coupled elevation and azimuth dynamics responses of the weapon. The weapon dynamics model coupled with the integrated ride and cornering dynamics model of the military vehicle, would be useful for implementation of a suitable robust gun control system in military vehicles.
Widening the Lens: An Ecological Review of Campus Sexual Assault
Authors: Moylan Carrie A. , Javorka McKenzie
Published: February 2018

Varying prevalence rates of sexual violence across colleges and universities indicate the need to understand institutional factors underlying such variation; however, research often focuses exclusively on individual risk and protective factors, which both under theorizes and under explains the phenomenon of campus sexual assault. In this review, we propose that broadening to include campus- and contextual-level factors is necessary to fully explain campus sexual assault. Using an ecological approach, we identify and synthesize research related to campus-level variation in sexual violence, including availability of campus services and resources for survivors, institutional risk factors such as alcohol and party culture, athletics, and fraternities, and the impact of policies at the state and federal levels. Suggestions are made for conducting additional research at the campus level and implications of reframing campus sexual assault from an institutional lens are discussed, including the importance of this approach for practice, evaluation, and policy.
Adapting Evidence-Based Teen Pregnancy Programs to Be LGBT-Inclusive: Lessons Learned
Authors: Boyce Karen Stradford , Travers Madeline , Rothbart Betty , Santiago Vivian , Bedell Jane
Published: February 2018

Context. Lesbian, gay, bisexual, and transgender (LGBT) youth show higher rates of sexual risk behaviors than heterosexual and cisgender youth; yet, most school-based sexual health education is largely heteronormative and cisnormative and does not recognize the spectrum of sexual and gender identity. New York City’s Departments of Health and Education collaborated to create an LGBT-inclusive supplement to the Reducing the Risk curriculum and implement it in 21 South Bronx high schools. Method. Teachers completed an electronic survey to report the number of students reached and an online log to measure curriculum adherence. Students were administered an anonymous 74-item pre- and posttest to measure demographics, sexual health knowledge, and student satisfaction with the curriculum. Chi-square and t tests were used to assess differences in student demographics and changes in knowledge scores. Results. Reducing the Risk was implemented in 21 schools reaching 230 classes and 5,673 students; with 161 classes receiving the supplement. Teachers reported completing an average of 70% of LGBT supplement activities. Students who received the supplement reported higher satisfaction and greater knowledge scores than students who did not. Conclusion. New York City experience shows that being more inclusive of LGBT teens while implementing preexisting evidence-based sexual and reproductive health programs is possible and replicable.
Extrinsic Compression of the Ovation Stent-Graft Following Glue Embolization for Type II Endoleak: An Unusual Complication
Authors: Ni Wenwen , Leong Sum , Chng Jack Kian , Tay Kiang Hiong
Published: February 2018

Purpose: To describe a case of extrinsic compression of the Ovation stent-graft following glue embolization for type II endoleak. Case Report: A 75-year-old man with a past history of ischemic heart disease and endovascular aneurysm repair with an Ovation stent-graft was admitted for treatment of type II endoleaks from the right L2 and left L4 lumbar arteries with egress via the inferior mesenteric and right L4 lumbar arteries, respectively. Successful embolization was performed via a translumbar sac puncture with a combination of coils and histoacryl glue. On final angiography severe lumen narrowing of the unsupported portion of the Ovation stent-graft was seen owing to extrinsic compression by the glue. This was successfully salvaged with percutaneous transarterial kissing balloon angioplasty. Conclusion: Aortic lumen narrowing caused by extrinsic compression of an Ovation stent-graft following glue embolization of type II endoleak is an unusual and potentially problematic complication.
The changes in placental IL-10 level, placental IFN-γ level, and placental VCAM-1 expression in endothelial dysfunction model using Mus musculus which had mild regular exercise
Authors: Noor Meitria Syahadatina , Santoso Budi , Triawanti  , Widjiati
Published: February 2018

Preeclampsia is a syndrome that consists of hypertension (blood pressure ⩾ 140/⩾ 90 mm Hg) and proteinuria (⩾ 0.3 g/24 h). It occurs after 20 weeks of gestation. Preeclampsia and eclampsia are the causes of maternal mortality in Indonesia. Hypertension is the second cause of maternal mortality in Indonesia after hemorrhage. The mechanism of preeclampsia might occur through inflammation process that would cause endothelial dysfunction. Preeclampsia leads to complications both in the mother and the fetus. The effective management for preeclampsia is prevention, including mild regular exercise since early pregnancy. This research objective was to analyze the inflammation process and endothelial dysfunction in an endothelial dysfunction model using mice who had mild regular exercise since early pregnancy. There were three treatment groups with 14 mice each, namely, normal pregnancy group (K1), endothelial dysfunction group (K2), and endothelial dysfunction group with mild regular exercise since early pregnancy (K3). The mice in K3 group had mild regular exercise by doing a treadmill for 18 min once every 2 days. The results showed that the placental interleukin 10 (IL-10) level in K3 was lower than that in K2 (599.86 vs 636.36, P = 0.001), the placental interferon gamma (IFN-γ) level in K3 was higher than that in K2 (322.36 vs 299.50, P = 0.002), and the placental vascular cell adhesion molecule 1 (VCAM-1) expression in K3 was higher than that in K2 (5.33 vs 1.67, P = 0.000). It can be concluded that mild regular exercise since early pregnancy did not decrease the inflammation process and the expression of placental VCAM-1 in endothelial dysfunction model using mice.
Is ultrasound screening for vasa praevia clinically justified and a financially viable screening test? A literature review
Authors: Coleman Gillian , Venables Heather
Published: February 2018

Vasa praevia is an obstetric complication currently not screened for within the United Kingdom, which if undetected prenatally can lead to fetal death when the membranes rupture. Internationally, guidelines are available providing guidance on the best screening policy and management pathways. However, the UK National Screening Committee and Royal College of Obstetricians and Gynaecologists do not support screening due to a lack of evidence. Recent studies explore the ability of ultrasound to detect vasa praevia prenatally in both the general and high-risk populations. Whilst there is no consensus on the ‘best’ screening strategy, the majority of authors note that targeted screening of the high-risk population is the most achievable and cost-effective strategy. Although not infallible, a standard screening protocol could identify the majority of cases in the high-risk group. Introduction of a screening strategy would affect training needs of professionals within the UK and would have implications on the need to produce guidelines on management and quality assurance. Further research is also needed to define a relevant high-risk population and explore how this would impact on service provision. This review explores the current evidence base for systematic screening and the implications for service.
Validation of the Australian Football League Player Ratings
Authors: McIntosh Sam , Kovalchik Stephanie , Robertson Sam
Published: February 2018

This study investigated the validity of the official Australian Football League Player Ratings system. It also aimed to determine the extent to which the distribution of points across the 13 rating subcategories could explain Australian Football League match outcome. Ratings were obtained for each player from Australian Football League matches played during the 2013–2016 seasons, along with the corresponding match outcome (Win/Loss and score margin). The values for each of the 13 subcategories that comprise the ratings were also obtained for the 2016 season. Total team rating scores were derived as an objective team outcome for each match. Percentage agreement and Pearson correlational analyses revealed that winning teams displayed a higher total team rating in 94.2% of matches and an association of r = 0.96 (95% confidence interval = 0.95–0.96) between match score margin and total team rating differential, respectively. A Partial Decision Tree (PART) analysis resulted in seven rules capable of determining the extent to which relative contributions of rating subcategories explain Win/Loss at an accuracy of 79.3%. These models support the validity of the Australian Football League Player Ratings system and its use as a pertinent system for objective player analyses in the Australian Football League.
Lower gastrointestinal bleeding
Authors: Babakhanlou Rodrick
Published: February 2018

Lower intestinal bleeding covers a spectrum of intestinal bleeding originating distal to the ligament of Treitz. In 11% of cases, the source of bleeding will be found in the upper gastrointestinal tract. Lower intestinal bleeding can occur either in the form of fresh blood, also known as haematochezia, or in the form of black, tarry and foul-smelling stools, also known as melaena. It can be chronic and mild or severe and life-threatening. This article will focus on the common causes of lower intestinal bleeding, clinical presentation, assessment and management, as well as providing guidance for referral to secondary care.
Social media pedagogy: Applying an interdisciplinary approach to teach multimodal critical digital literacy
Authors: Talib Saman
Published: February 2018

Social media permeates the daily lives of millennials, as they use it constantly for a variety of reasons. A significant contributing factor is the availability of social media through smartphones and mobile apps. This kind of immersive and complex media environment calls for a literacy pedagogy that prepares students to understand, engage with, and adapt to social media that are inevitably going to remain a part of their lives. Research into digital literacy/literacies has sought to address the development of tools and methods to aid college students in becoming more situated and adept digital citizens. This article extends the conceptualization and application of digital media literacy through the inclusion of a critical, multimodal, and interdisciplinary pedagogical approach. The paper illustrates that critical digital literacy drawing upon multimodal and interdisciplinary analysis is imperative in preparing students to manage the predominance of social media in their lives.
Bilateral bronchial stent deployment for palliative treatment of a compressive intrathoracic mass in a cat
Authors: Borgeat Kieran , Simpson Kerry , Reese David , Wilson Helen , Potter Joanna , Ogden Daniel
Published: February 2018

Case summary

Bronchial stents may be useful to relieve clinical signs of extraluminal compression. Herein we describe a case which, to our knowledge, is the first cat where bilateral bronchial stents have been used clinically. Respiratory signs of principal bronchial compression were alleviated after the stent procedure. Minor complications occurred, specifically: severe hypoxia during stent deployment; a transient, self-limiting postoperative pneumothorax possibly associated with ventilation-induced lung injury; bronchopneumonia (possibly pre-existing); and transient worsening of cough postoperatively. Stents were well- tolerated long- term. The cat was euthanased at 44 weeks post-stent procedure, owing to clinical signs of regurgitation, seemingly related to oesophageal dysfunction associated with tumour invasion.

Relevance and novel information

In this case, it appeared that bronchial stents were feasible and the procedure was associated with long-term improvement in respiratory signs related to extraluminal bronchial compression.
ICD-10 Versus DSM-5 on Cultural Issues
Authors: Paniagua Freddy A.
Published: February 2018

Mental health practitioners in the United States often use two classification systems for mental disorders, namely, the International Classification of Diseases (ICD) and the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5). A critical issue when diagnosing people with mental disorders is to ensure that cultural variables do not potentially explain the presentation of symptoms. A fundamental difference between the two classification systems is that the ICD is mute regarding the need to consider such variables in this context of diagnosing people with mental disorders, whereas the DSM-5 does alert mental health practitioners that they should not make a diagnosis in this context without considering the cultural variables potentially affecting the assessment and diagnosis of such disorders. This difference between the two classification systems is illustrated with a sample of mental disorders in both systems.

Published: February 2018

In this study, YouTube videos concerning public education were identified and evaluated. The researcher typed the term public education into the YouTube search bar and then analyzed the first 60 videos provided by the site. Two coders (the researcher included) independently coded the videos as either negative, neutral, or positive in light of the following question: “Is public education portrayed in this video in a negative, neutral, or positive manner?” The theory of Internet information gatekeepers and the theory of social construction of reality provided the theoretical framework for the study, and the results were discussed through the lenses provided by these theories.
A Critique of Development in India’s Predominantly Adivasi Regions with Special Reference to the Hos of India’s Jharkhand
Authors: Kumar Dhiraj , Puthumattathil Antony
Published: February 2018

This article seeks to look at the idea of development interventions (DI) in predominantly Adivasi regions that focus on the extraction of abundant forest and mineral wealth to benefit regions beyond Adivasi territories. While this process deprives Adivasis of their subsistence needs, it invokes resistance and resultant conflicts. Such interventions and consequent conflict need sociological elaboration. Hence, using two case studies, we explicate DI as a self-reproducing system embodying colonialism and racism as process and praxis. This article investigates how development facilitates resource accumulation and socio-economic differentiation of a few and pauperization of the rest. It further tries to find out how these systemic processes have historically found favour with political Brahmanism (PB), the dominant taken-for-granted socio-religious and political ideology (doxa) in India. In contrast to PB, Adivasis’ alternative imaginations based on their sacral polity (SP) are highlighted. Then, we contrast SP with PB and the dominant neoliberal development paradigm. SP has been contrasted with PB and the dominant neoliberal development paradigm. This comparison facilitates the conclusion that the secret of sustainable development rests with Adivasi social formations that adhere to SP-based self-restriction and egalitarian democratic principles. However, historical domination and co-option of Adivasi engender ambivalence of violence which helps to perpetuate ‘development’ as a colonial and racist system among Adivasi in forms of DI.

Published: February 2018

Purpose

To investigate for a prognostic index (PI) to personalize recommendations for salvage intensity-modulated radiotherapy (IMRT) in patients with locally recurrent nasopharyngeal carcinoma (lrNPC).

Methods

Patients with lrNPC from two academic institutions (Sun Yat-Sen University Cancer Center [SYSUCC-A; n = 251 (training cohort)] and National Cancer Centre Singapore [NCCS; n = 114] and SYSUCC-B [n = 193 (validation cohorts)]) underwent salvage treatment with IMRT from 2001 to 2015. Primary and secondary clinical end points were overall survival (OS) and grade 5 toxicity-free rate (G5-TFR), respectively. Covariate inclusion to the PIs was qualified by a multivariable two-sided P < .05. Discrimination and calibration of the PIs were assessed.

Results

The primary PI comprised covariates that were adversely associated with OS in the training cohort (gross tumor volumerecurrence hazard ratio [HR], 1.01/mL increase [ P < .001], agerecurrence HR, 1.02/year increase [ P = .008]; repeat IMRT equivalent dose in 2-Gy fractions [EQD2] ≥ 68 Gy HR, 1.42 [ P = .03]; prior radiotherapy-induced grade ≥ 3 toxicities HR, 1.90 [ P = .001]; recurrent tumor [rT]-category 3 to 4 HR, 1.96 [ P = .005]), in ascending order of weight. Discrimination of the PI for OS was comparable between training and both validation cohorts (Harrell’s C = 0.71 [SYSUCC-A], 0.72 [NCCS], and 0.69 [SYSUCC-B]); discretization by using a fixed PI score cutoff of 252 determined from the training data set yielded low- and high-risk subgroups with disparate OS in the validation cohorts (NCCS HR, 3.09 [95% CI, 1.95 to 4.89]; SYSUCC-B HR, 3.80 [95% CI, 2.55 to 5.66]). Our five-factor PI predicted OS and G5-TFR (predicted v observed 36-month OS and G5-TFR, 22% v 15% and 38% v 44% for high-risk NCCS and 26% v 31% and 45% v 46% for high-risk SYSUCC-B).

Conclusion

We present a validated PI for robust clinical stratification of radioresistant NPC. Low-risk patients represent ideal candidates for curative repeat IMRT, whereas novel clinical trials are needed in the unfavorable high-risk subgroup.

Published: February 2018

Objective:

To evaluate the quantification performance of the perfusion fraction (f) measured with intravoxel incoherent motion (IVIM) MR imaging in a comparison with the histological vascular density in meningiomas.

Methods:

29 consecutive patients with meningioma (59.0 ± 16.8 years old, 8 males and 21 females) who underwent a subsequent surgical resection were examined with both IVIM imaging and a histopathological analysis. IVIM imaging was conducted using a single-shot SE-EPI sequence with 13 b-factors (0, 10, 20, 30, 50, 80, 100, 200, 300, 400, 600, 800, 1000 s mm−  2) at 3T. The perfusion fraction (f) was calculated by fitting the IVIM bi-exponential model. The 90-percentile f-value in the tumor region-of-interest (ROI) was defined as the maximum f-value (f-max). Histopathological vascular density (%Vessel) was measured on CD31-immunostainted histopathological specimens. The correlation and agreement between the f-values and %Vessel was assessed.

Results:

The f-max (15.5 ± 5.5%) showed excellent agreement [intraclass correlation coefficient (ICC) = 0.754] and a significant correlation (r = 0.69, p < 0.0001) with the %Vessel (12.9 ± 9.4%) of the tumors. The Bland-Altman plot analysis showed excellent agreement between the f-max and %Vessel (bias, −2.6%; 95% limits of agreement, from −16.0 to 10.8%). The f-max was not significantly different among the histological subtypes of meningioma.

Conclusion:

An excellent agreement and a significant correlation were observed between the f-values and %Vessel. The f-value can be used as a noninvasive quantitative imaging measure to directly assess the vascular volume fraction in brain tumors.

Advances in knowledge:

The f-value measured by IVIM imaging showed a significant correlation and an excellent agreement with the histological vascular density in the meningiomas. The f-value can be used as a noninvasive and quantitative imaging measure to directly assess the volume fraction of capillaries in brain tumors.

Reflections on the use of the World Health Organization’s (WHO) OneHealth Tool: Implications for health planning in low and middle income countries (LMICs)
Authors: Wong John Q. , Haw Nel Jason , Uy Jhanna , Bayani Diana Beatriz
Published: February 2018

The World Health Organization (WHO) launched the OneHealth Tool (OHT) to help low and middle income countries to develop their capacities for sector-wide priority setting. In 2016, we sought to use the OHT to aid the Philippine Health Insurance Corporation (PHIC), the national health insurer of the Philippines, in decisions to expand benefit packages using cost-effectiveness analyses. With technical support from the WHO, we convened health planning officers from the Philippine Department of Health (DOH) and the Philippine Health Insurance Corporation (PHIC) conduct generalized cost-effective analyses (GCEA) of selected un-financed noncommunicable disease interventions using OHT. We collected epidemiological and cost data through health facility surveys, review of literature such as cost libraries and clinical practice guidelines, and expert consultations.

Although we were unable to use GCEA results directly to set policy, we learnt important policy lessons which we outline here that might help inform other countries looking to inform service coverage decisions. Additionally, the entire process and GCEA visualizations helped high-level policymakers in the health sector, who have traditionally relied on ad hoc decision making, to realize the need for a systematic and transparent priority-setting process that can continuously provide the evidence needed to inform service coverage decisions.

Ancestral morbid fascinations: Reformulating local culture through metal music in Puerto Rico
Authors: Rivera-Segarra Eliut , Varas-Díaz Nelson , Mendoza Sigrid , Díaz Xaymara
Published: February 2018

There has been an increased interest in and attention to the integration of local culture into the metal music, including metal being produced in Puerto Rico. During the 1990s, the metal genre, a musical style still perceived as a foreign (read: US) entity, incorporated Puerto Rican culture to its musical output in a celebratory manner. This tendency has changed, however, and today the scene is experiencing a thematic consolidation through lyrics and imagery that moves away from the celebratory strategies, opting instead for a more critical perspective regarding local culture. This article documents how the metal community in Puerto Rico has brought together metal music and local culture in a critical manner by emphasizing the reformulation of local elements. We undertook a case study that includes tools such as interviews and the analysis of visual documents. While cultural productions have usually been received by local audiences in an irreflexive and celebratory manner, more recently, the genre has produced music and art that use cultural elements to question this traditional manner of reception, highlighting through a critical gaze the way in which cultural productions have also alluded to morbid and grim fascinations. This examination will focus on the vejigante, a figure greatly depicted throughout cultural celebrations and in the arts in Puerto Rico. We discuss the way in which metal music employs its cultural production as a reflection of the dark side of Puerto Rican society, a topic which the majority of the population would rather leave untouched.
‘If you got a tape on, you’re committed’: The revival of cassette tapes in Toronto’s New Wave of Traditional Heavy Metal scene
Authors: Udarchik Anastasia
Published: February 2018

At the height of music digitization and dematerialization, we still find collectivities of people who use obsolete forms of music media not out of necessity, but as a conscious and meaningful choice. This article focuses on a case study of a surprising revival of cassette tapes in the New Wave of Traditional Heavy Metal (NWOTHM) scene in Toronto, Canada. I consider two broad questions. First, if the music of the bands in the scene can be easily downloaded or ripped off of a CD, and conveniently stored on computers and other devices, what is the appeal of cassette tapes for their consumers? And second, what new meanings have been ascribed to cassette tapes in the Toronto NWOTHM scene – has the main function of cassettes as a music storage medium changed entirely? In this article, I (1) propose that Toronto NWOTHM scene members have rekindled an attraction to physical media formats to close the tangibility gap between music and listener; (2) suggest that subjective media associations between various time periods and/or music genres foster the historically informed consumption of cassettes; (3) demonstrate these two points in the traditional heavy metal subculture in Toronto and (4) outline new meanings that cassettes have undertaken in this context, such as souvenir, materialization of subcultural capital and symbol of commitment.
Throat singing as extreme Other: An exploration of Mongolian and Central Asian style in extreme metal
Authors: Spracklen Karl
Published: February 2018

Throat singing is a form of singing practised in a number of cultures, but it is not part of the premodern folk cultures of Western Europe that shaped contemporary Western popular culture. In contemporary Western music, throat singing from Central Asia is used or sampled in global fusion and dance music as an example of the mystical, timeless orient. In world music, another Western form of music, artists from China, Mongolia and Tuva who incorporate throat singing and roots music forms have become popular acts at festivals and the touring circuit. Throat singing has also been used by extreme metal bands from Asia to signify their authenticity and their connection to this traditional culture. In this article, I explore how throat singing is used by performers and consumers to construct belonging, authenticity, identity and extremity. I focus in particular on how throat singing and traditional cultural tropes are used by the Chinese folk metal band Tengger Cavalry, and Darkestrah, a black metal band from Kyrgyzstan.
Decay as a black metal symbol
Authors: Hoffin Kevin
Published: February 2018

This article intends to dissect black metal’s interestingly twisted relationship with decay. A deep study encompassing symbols of atrophy, with the eventual intention of observing and analysing them through a kaleidoscope of philosophical thought, influenced by, amongst others, the musings of Bataille, Kant and Nietzsche. Issues appearing in both the real and the metaphorical will be placed under inspection, and a suitably blackened light will be shone towards the extent of how black metal exists and thrives in the organic collapse of matter and sound. There will be discussions on how black metal has itself become attuned to decay and how the two processes feed off each other, exist in harmonic conjunction and on rare occasions, oppose the other’s being. How black metal has metastasized with atrophy. Here we shall see two forces inexplicably intertwined, the numerous links given exposure and attempted understanding in the realm of black metal theory.
Expressive and creative writing in the therapeutic context: From the different concepts to the development of writing therapy programs
Authors: Costa Ana Catarina , Abreu Manuel Viegas
Published: February 2018

One of the main aims of this scoping selective review is to clarify the differences between expressive and creative writing in the mental health context, not only at a conceptual level but also regarding its therapeutic effects. The other one is to identify the more efficient ways to develop therapeutic creative writing programs for a clinical population. Considering these specific aims, we employed a selective review on the writing therapeutic literature. We found that, although expressive writing is clearly defined and its benefits on mental health empirically well established, creative writing lacks a consistent conceptualization in clinical settings. Similarly, we reported several studies focusing in the therapeutic benefits of poetry, but other writings genres receive much less attention and are even more insufficiently defined. Since some studies support the idea that giving a significant content to a text is more beneficial, and considering that writing creatively offers new perspectives and meanings to the information, we propose that the development of creative writing programs should be tried. Aiming to develop such programs in the future, we give some suggestions based on already studied expressive writing methods.

(OR) plant, which is used for folk-medicine and food in the Sanliurfa region of Turkey. The antioxidant activity of the extract was investigated using total phenolics, flavonoids, ABTS and CUPRAC methods. Phenolic component analysis of the plant extract was performed by LC-MS/MS. The anti-cancer property of OR extract was investigated on human colon (DLD-1), endometrium (ECC-1) cancer cells and embryonic kidney (HEK-293) cells. Cytotoxic effects were defined with MTT, apoptotic activity with DNA fragmentation ELISA and AO/EB fluorescent staining, the genotixic effect with the comet assay and the intracellular oxidative status with TAS and TOS methods. As a result of the study, it was determined that OR extract showed an antioxidant effect, and as a result of the content analysis made with LC/MS-MS, phenolic components were determined, the most abundant being cosmosiin, followed by cinnamic acid, p-coumaric acid and Quinic acid. OR extract showed cytotoxic activity on DLD-1 and ECC-1 cancer cells, while the cytotoxic effect on HEK-293 cells was determined to be low.  It was determined that through OR extract, by increasing the intracellular amount of free radicals on cancer cells, led to DNA damage, which consequently led to apoptosis of the cancer cells.

Citrus Limon Oil (CLO) is known as antioxidant resource and contains limonoids, flavonoids and phenolic compounds. This study was conducted to investigate the effects of different levels of CLO on blood parameters and antioxidant status in Afshari ewes. Six adults Afshari ewes (3-4 years old and 51±5 kg) were randomly allocated to 3í—3 Latin square design with three diets in 21 days period. Dietary treatments included:1) control diet, 2) control diet with 200 mg/day CLO, and 3) control diet with 400 mg/day CLO. To evaluate the antioxidant effect of the CLO, sustainable elimination of free radicals by DPPH and ABTS methods were used. The antioxidant activity of essential oils in DPPH method at doses of 32.5, 45, 130, 260 and 520 mg/ml were 9, 16, 31, 49 and 89%, respectively. Also, antioxidant activity of essential oils in ABTS method at doses of 32.5, 45, 130, 260 and 520 mg/ml were 49, 73, 81, 89 and 95%, respectively. CLO treatments did not affect glucose, blood urea nitrogen, albumin, total protein, low density lipoprotein, while improved the concentration of high-density lipoprotein (P>0.01). Results showed that supplementation with CLO significantly decreased (P<0.01) cholesterol, triglycerides and very low density lipoprotein concentrations compared with control. There was no significant difference in analyzed blood bio-chemicals and serum enzymes level between different antioxidant activity methods and groups, suggesting general well-being of ewes. These results suggest that, CLO supplementation had a positive impact on blood traits and antioxidant status of the Afshari ewes.

Celem artykułu jest ujawnienie ograniczeń związanych ze standaryzacją CSR. W pierwszej części dokonano rekonstrukcji celów i form standaryzacji CSR, następnie przedstawiono spektrum standardów CSR, pokazując możliwe ich uporządkowania. Kolejna część artykułu sięga do danych empirycznych weryfikujących efektywność standardów CSR. Okazuje się że często nie spełniają one swojej roli, a nawet zwiększają poziom nieodpowiedzialności. W ostatniej części artykułu podjęto analizę przyczyn zawodności tych standardów.
Indeksy społecznej odpowiedzialności jako metoda pomiaru działań CSR w przedsiębiorstwach
Authors: Czopik Szymon
Published: February 2018

W ostatnich latach zauważalny jest wzrost znaczenia koncepcji społecznej odpowiedzialności biznesu (corporate social responsibility – CSR) w przestrzeni gospodarczej. W związku z tym coraz większym powodzeniem wśród inwestorów cieszą się narzędzia pozwalające ocenić działalność spółek pod kątem ich społecznej odpowiedzialności. Szczególne znaczenie sprawozdawczości w tym zakresie jest zauważalne po ostatnim kryzysie finansowym, który nadszarpnął zaufanie na rynku globalnym. Wychodząc naprzeciw oczekiwaniom inwestorów, instytucje finansowe publikują indeksy społecznej odpowiedzialności. Obecnie funkcjonuje kilkadziesiąt indeksów giełdowych tworzonych zgodnie z kryteriami CSR, a wśród nich najpopularniejsze to Dow Jones Sustainability Index oraz FTSE4GOOD Index, a także pierwszy w Europie Środkowo-Wschodniej – RESPECT Index. Przedsiębiorstwa coraz chętniej wdrażają rozwiązania z zakresu CSR i chętnie zgłaszają się do indeksów społecznej odpowiedzialności. Niestety mimo dużej świadomości istnienia indeksów nie są one kluczowym kryterium branym pod uwagę przy podejmowaniu decyzji inwestycyjnych przez uczestników rynku.
Pojęcie zasad prawa w świetle idei pojęć co do istoty kwestionowanych
Authors: Obuchowski Szymon
Published: February 2018

Pomimo istnienia wielu opracowań dotyczących teoretycznych właściwości „zasad prawa” żadna z koncepcji obecnych w polskim porządku prawnym nie została dotąd uznana za dominującą i bezsprzecznie trafniejszą niż pozostałe. Podobna sytuacja panuje w światowej teorii prawa. W niniejszym opracowaniu podjęto próbę zbadania przyczyn tego stanu rzeczy przez zaprezentowanie założeń mało znanej w nauce polskiej idei „pojęć co do istoty kwestionowanych” (essentially contested concepts – ECC), stworzonej przez Waltera B. Galliego i zastosowanie jej do analizy pojęcia zasad prawa. Istnieją dwie główne możliwe interpretacje idei. Zależnie od poglądów przyjętych w tej kwestii, może ona pełnić rolę analitycznego wzorca opisującego typowy zestaw cech charakteryzujących pojęcia wyjątkowo w nauce sporne, w świetle których warto je wraz z otaczającą dyskusją przestudiować. Drugą możliwość stanowi uznanie jej za ontologiczną „hipotezę wyjaśniającą”, zgodnie z którą każdemu ECC z konieczności towarzyszy nierozstrzygalność debaty o właściwy sposób użycia. Niezależnie od zajętego stanowiska, prześwietlenie „zasad prawa” z wykorzystaniem metodologii ECC pozwala pełniej spojrzeć na dotyczącą ich dyskusję z perspektywy „zewnętrznej”. To zaś pozwala sformułować tezę, że argumentacja za konkretnymi koncepcjami zasad powinna w większym stopniu obejmować użyteczność uważanej za słuszną teorii niż konwencjonalne z natury argumenty dotyczące tego, czym zasady w rzeczywistości są.
The effect of serum proteins on apatite growth for 45S5 Bioglass and common sol-gel derived glass in SBF
Authors: Lin Sen , Jones Julian R.
Published: February 2018

The inhibitive effects of serum proteins on apatite growth was compared between melt-derived 45S5 Bioglass® and sol-gel derived bioactive glass of the 70S30C (70 mol% SiO2, 30 mol% CaO). By using techniques of XRD, TEM and Raman spectroscopy, the transformation of amorphous calcium phosphate to crystalline apatite, and the resulting size and aspect ratio of the crystals, in simulated body fluid (SBF), was seen to decrease in the presence of serum. XRD showed more rapid HA formation on Bioglass particles, compared to that forming on 70S30C particles, however TEM showed similar size and frequency of the needle-like crystals. Phosphate reduction in SBF was similar for Bioglass and 70S30C. Calcium carbonate formation was more likely on the phosphate-free sol-gel glass than on Bioglass.

A novel Dye-decolorizing peroxidase from the basidiomycete Pleurotus sapidus was screened for dyedecolorizing peroxidase activity with 2,2‘-azino-bis(3- ethylbenzothiazoline-6-sulfonic acid), Remazol Brilliant Blue R and Guaiacol. Additionally, the catalytic efficiency on degrading β-carotene into volatile products, and the catalyst storage stability with three different additives were also studied. The apparent inhibition constant (KS) was 51.7 μM. Optimal reaction rates (Vmax) and affinity constants (Km) towards the reducing substrates were obtained using Michaelis-Menten kinetic theory. The trend in the calculated Km’s was found to be 7.0 mM > 0.524 mM > 0.051 mM for Guaiacol, 2,2‘-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) and Remazol Brilliant Blue R. The storage stability of the catalyst was evaluated with 7.0% w/v PEG400, 7.0% w/v PEG1450 and 0.1% w/v Tween®80 at 5°C over a period of 45 days. The study revealed the longest activity conservation with PEG1450, where rDyP had lost 30% of initial activity. The enzyme solution presented similar pH and temperature dependence to known fungal dye-decolorizing peroxidases with most prolific enzymatic activities registered at pH 4.0 and temperatures below 30°C. An interesting property of the catalyst was oxidation observed in the absence of hydrogen peroxide.

Published: February 2018

There has been a strong interest worldwide in developing suitable technologies that can derive chemicals and materials from renewable biomass in a number of applications, including corrosion inhibitors. In spite of the efficacy of conventional inhibitors in corrosion control, current corrosion inhibitors exhibit toxicity and/or are non-biodegradable. Therefore, industry efforts are leading to the development of non-toxic and environmentally friendly “green” corrosion inhibitors from renewable resources. Extensive studies of different bio-based inhibitors show that a vast number of phytochemicals can be used as efficient corrosion inhibitors. This paper provides a comprehensive review of the corrosion inhibition properties of plant-derived chemicals classified under the parameters provided by botanical chemistry.
Prissy’s Quittin’ Time: The Black Camp Aesthetics of Kara Walker
Authors: Stephens Brian
Published: February 2018

Through a close reading of Walker’s first silhouette instalment-the audaciously titled Gone, An Historical Romance of a Civil War as it Occurred Between the Dusky Thighs of One Young Negress and Her Heart (1994)-this article examines how Walker utilises black camp to undermine both white supremacist and restrictive black uplift discourse. To be sure, the article is not an attempt to conflate these two, for the former is powerfully worse than the latter. However, it is necessary to explore how both discourses reinforce essentialist articulations of blackness and also to examine how black camp is a provocative analytic for their simultaneous disruption. Camp is usually understood as a queer-derived cultural practice that inflates identity to expose the constructed nature of gender. However, this article shows that black articulations of camp inflate identity to demonstrate the fiction of race as well.
