Improved air valve design using evolutionary polynomial regression
Authors: Balacco G. , Laucelli D.
Published: June 2019

Air valves are usually sized by heuristic methods or, sometimes, even oversized. Although the technical literature has long focused on the correct sizing of air valves to reduce the overpressure generated by the filling of a pipe, the phenomenon is complex and does not seem to be representable by physically based equations in an easy way, to be of practical use for technicians and designers. In this paper, air valve design is approached through an alternative data-modelling approach, based on evolutionary polynomial regression, with the aim to provide symbolic formulas of variable complexity and accuracy, suitable for physical interpretation, and at the same time easy to be used and applied for design purposes. The present investigation suggests a design formula that, given the geometric parameters of the pipeline system where the air valve is installed, provides the maximum tolerable overpressure, thus allowing the optimal air valve orifice size to be identified.
La2O3-modified MCM-41 for efficient phosphate removal synthesized using natural diatomite as precursor
Authors: Jia Xiaoning , He Xiaojuan , Han Kaixuan , Ba Yuhong , Zhao Xia , Zhang Qingfang
Published: May 2019

In this study, an ordered mesoporous silica modified with lanthanum oxide was synthesized using diatomite as silica source and applied for adsorption of phosphate from aqueous solution. By taking cost-effectiveness for practical application into consideration, the adsorbent with a theoretical La/SiO2 molar ratio of 0.2 (La0.2M41) possessed a promising performance. In the batch adsorption tests, the adsorbents with La2O3 loading possessed markedly enhanced adsorption capacities. Phosphate uptake by La0.2M41 was pH-dependent with the highest sorption capacities observed over a pH range of 3.0–6.0. Coexistent anions displayed an adverse effect on phosphate adsorption following the order of CO32−  > F−  > NO3− > Cl− > SO42−. In the kinetic study, phosphate adsorption onto La0.2M41 followed the pseudo-second-order equation better than the pseudo-first-order, suggesting chemisorption. The Langmuir isothermal model well described the adsorption isotherm data, showing a maximum adsorption capacity for phosphate of up to 263.16 mg/g at 298 K. In a real treated wastewater effluent with phosphate concentration of 2.5 mg P/L, La0.2M41 efficiently reduced the phosphate concentration to 28 µg P/L.
The Worrying Trend of Diabetes Mellitus in Saudi Arabia: An Urgent Call to Action
Authors: Robert Asirvatham A. , Al Dawish Mohamed A.
Published: May 2019

From last few years, the pervasiveness of diabetes mellitus (DM), in Saudi Arabia, is growing
at a frightening rate. Overall, one-fourth of the adult population is affected by DM, which is further
predicted to rise to more than double by the year 2030. The most alarming is possibly the escalation
propensity of diabetes, in recent years, where a nearly ten-fold increase has been witnessed over the past
thirty years in Saudi Arabia. However, the number of research arbitrations on the prevalence and incidence
of DM is woefully inadequate, as compared to developed countries. Apart from this, most of the
existing research data carried out in Saudi Arabia is cross-sectional, with small sample sizes, which
most often involve only certain parts of the country. Consequently, the present scenario demands more
multidimensional and multisectoral research to strengthen the evidence base and to accumulate greater
knowledge as a basis for measures and programmes to confront diabetes and its complications. Thus,
the present report makes an attempt to depict the current trend of diabetes as well as intends to put forward
essential measures for controlling diabetes in Saudi Arabia.
Gene-environment Interaction on the Risk of Type 2 Diabetes Among Ethnic Minority Populations Living in Europe and North America: A Systematic Review
Authors: Zafarmand Mohammad H. , Tajik Parvin , Spijker René , Agyemang Charles
Published: May 2019

Background:

The body of evidence on gene-environment interaction (GEI) related to type 2
diabetes (T2D) has grown in the recent years. However, most studies on GEI have sought to explain
variation within individuals of European ancestry and results among ethnic minority groups are inconclusive.

Objective:

To investigate any interaction between a gene and an environmental factor in relation to
T2D among ethnic minority groups living in Europe and North America.

Methods:

We systematically searched Medline and EMBASE databases for the published literature in
English up to 25th March 2019. The screening, data extraction and quality assessment were performed
by reviewers independently.

Results:

1068 studies identified through our search, of which nine cohorts of six studies evaluating
several different GEIs were included. The mean follow-up time in the included studies ranged from 5 to
25.7 years. Most studies were relatively small scale and few provided replication data. All studies included
in the review included ethnic minorities from North America (Native-Americans, African-
Americans, and Aboriginal Canadian), none of the studies in Europe assessed GEI in relation to T2D
incident in ethnic minorities. The only significant GEI among ethnic minorities was HNF1A
rs137853240 and smoking on T2D incident among Native-Canadians (Pinteraction = 0.006).

Conclusion:

There is a need for more studies on GEI among ethnicities, broadening the spectrum of
ethnic minority groups being investigated, performing more discovery using genome-wide approaches,
larger sample sizes for these studies by collaborating efforts such as the InterConnect approach, and
developing a more standardized method of reporting GEI studies are discussed.
Diagnosis of Lower Genital Tract Infection in Pregnancy: Routine Midtrimester High Vaginal Swab Followed by Gram Staining, Seems to be the Best Strategy
Authors: Poojari Vidyashree Ganesh , Vasudeva Akhila , Dawson Samantha , Kaipa Geetha , Eshwara Vandana , Tellapragada Chaitanya , Kumar Pratap
Published: June 2019

Background:

Screening of lower genital tract infection (LGTI) in mid-trimester prevents
preterm birth (PTB). There is no consensus on best screening methods for LGTI-symptoms, speculum
findings, a point of care tests or high vaginal swab microscopy.

Aim:

To know diagnostic accuracy of screening of lower genital tract infection (LGTI) in midtrimester
by clinical symptom/signs and point of care tests (viz Amsel’s criteria) as against the gold
standard microscopic tests using gram stain.

Settings and Design:

Prospective observational study in a tertiary care hospital over two years. The
study population included 228 antenatal women between 18th-24th weeks.

Materials and Methods:

Symptoms of vaginal discharge were noted. Speculum examination was
performed on all, to detect the type of discharge. High vaginal swabs were collected, subjected to
the point of care tests (Amsel’s criteria) as well as gram staining. Microscopy (Eg: Nugent’s criteria)
was taken as the gold standard, to which other methods were compared.

Results:

Thirty women (13.5%) were symptomatic. Among 198 that were asymptomatic,
91(45.92%) had LGTI. Speculum examination showed discharge in 221 (96.9%), but gram staining
showed LGTI in only 104 (45.61%), among whom 45 (19.7%) had partial Bacterial vaginosis (BV),
14(6.1%) had full BV, and 40(17.5%) had candidiasis. The commonest discharge was homogenous
thin white, suggestive of BV but 51% among them had normal vaginal flora (NVF); whereas 27%
of those labelled physiological discharge were positive for BV. The appearance of discharge and
gram stain thus did not correlate well. Amsel’s criteria had poor diagnostic accuracy compared to
Nugent’s, although negative predictive value were high.

Conclusion:

There is a high prevalence of LGTI, especially BV among asymptomatic pregnant
women at mid-trimester, best detected with a routine high vaginal swab and gram staining rather
than relying on symptoms/speculum findings/point of care tests. Such testing may guide appropriate
treatment for reducing the risk of PTB.
‘The game becomes the mediator of all your relationships’: Life Narrative and Networked Intimacy in Nina Freeman’s Cibele
Authors: Gallagher Rob
Published: June 2019

Nina Freeman’s 2015 videogame Cibele recounts its creator’s experience of falling in love with a fellow player of an online game. An interactive autobiography about a young woman sharing her life online, Cibele explores the terms on which new media enable users to narrate their experiences, represent themselves and forge identities. This article locates the game in relation to recent developments in life writing and independent game design, asking what digital technologies offer autobiographers as medium and as subject matter. It also frames Cibele as an attempt to challenge two dominant discourses about online culture: offering a counterpoint to narratives stressing the dangers facing young women who seek intimacy on the internet, Cibele also questions framings of networked intimacy as a necessarily deficient substitute for “the real thing.” Its oblique approach, however, in tandem with its commitment to witnessing the ambivalences and incoherencies of digital culture, have, I argue, led to these points being missed or misinterpreted by players, reflecting a longstanding tendency to dismiss and devalue women’s life writing.
processo de transição para a TV digital no Brasil
Authors: Cirne Lívia
Published: May 2019

O objetivo deste trabalho é apresentar uma reflexão crítica sobre o contexto de implementação da televisão digital (TVD) no Brasil. Neste sentindo, expõe-se sobre as tecnologias adotadas, as propriedades técnicas do sistema, a falta de inserção da sociedade civil e o processo de mudança de analógico para o digital. Observa-se que as barreiras técnicas e as discussões políticas no país, desde o primeiro momento, somadas às indefinições na regulamentação e as disputas comandadas pelos radiodifusores dificultaram o desenvolvimento e a disseminação da TV digital, provocando sequenciais adiamentos do switch-off (desligamento do sinal analógico). Enquanto isso, outras tecnologias de interatividade emergiram em paralelo (serviços de streaming nas smart TVs, chromecast, Apple TV, boxee, etc.), o que tornou a proposta do sistema brasileiro de TV digital mais obsoleta.

Authors: Maia Lídia Raquel Herculano
Published: May 2019

As eleições presidenciais brasileiras de 2014 foram marcadas por intenso processo de debates nas redes e nas ruas. O que propiciou o estabelecimento de vínculos dos eleitores entre si e com equipes de campanha. Nesse contexto, este artigo investiga os processos interacionais desenvolvidos nas páginas dos três principais candidatos à Presidência no Facebook. A partir de uma pesquisa empírica de viés qualitativo, discutimos a midiatização da política e tensionamos a circulação de sentidos em três prismas: a) o da participação do eleitor como coprodutor dos conteúdos que lhe são endereçados; b) o da formação de zonas de contato entre internautas e equipes de campanha e c) o das zonas de embates tecidas pelos eleitores no espaço destinado aos comentários. Concluindo que a política dos eleitores é a da disputa discursiva em espaços públicos simbólicos construídos nas redes sociotécnicas.

THE ANTI-TERRORIST FUNCTION OF THE RUSSIAN STATE: THE CONCEPT AND THE BASIC SIGNS
Authors: Mits Denis S
Published: May 2019

The article compares the important organizational and legal trends and prospects of antiterrorist activity, as well as the associated conceptual apparatus and the essence of terrorism. In the theory of criminal law, terrorism is defined as a threat to public security, in contrast to other areas of knowledge. This criminal phenomenon is implemented through the impact on a third party to the conflict (primarily ordinary citizens), that is, to encourage them to transform the foundations of statehood. In this regard, the system of management of information counteraction to terrorism, extremist activity and other forms of encroachment on the constitutional system, as well as other spheres of state functioning is gaining momentum.
MARIO FILHO E A "INVENÇÃO" DO JORNALISMO ESPORTIVO PROFISSIONAL
Authors: Capraro André Mendes
Published: May 2019

Mario Filho é apontado como a principal referência do jornalismo esportivo brasileiro. O objetivo do presente artigo é o de investigar como foi construída a máxima de que este agente seria o “inventor” do jornalismo esportivo moderno. Seguindo alguns “indícios”, principalmente a análise de crônicas esportivas, concluiu-se que foi sobretudo na cidade do Rio de Janeiro que Mario Filho se tornou uma celebridade do esporte. Por outro lado, seu alcance era limitado em outros centros. Quanto à transmissão recorrente de que o jornalista foi o “inventor” do jornalismo esportivo moderno, destaca-se a importância do reforço feito por reconhecidos jornalistas, intelectuais e artistas. No seio deste grupo, o mais engajado foi seu próprio irmão, Nelson Rodrigues.

Published: June 2019

Este artigo tem por objetivo apresentar as narrativas de mulheres em processo de envelhecimento diante de seus objetos de penteadeira, tratando mais especificamente de observar como a velhice é vista por elas. Estudos de autores como Guita Debert (1994; 1998; 1999), Maurice Halbwachs (2003), Ecléa Bosi (1994), Gilberto Velho (1986), entre outros, se entrelaçam aos conceitos apresentados por essas mulheres em seus relatos. A metodologia utilizada é a etnografia com observação participante, no espaço urbano em nossa sociedade contemporânea. A escuta atenta aos relatos de mulheres sobre o processo de envelhecimento aponta para a relevância de se refletir sobre o cotidiano dessas mulheres pertencentes a diferentes etnias, crenças e gerações no contexto da região do Vale dos Sinos/RS. As narrativas apresentam a sociabilidade, os laços familiares e o percurso profissional como dimensões fundamentais de reordenação de suas identidades de gênero ao chegarem na fase da velhice. A memória individual dessas mulheres dialoga com a memória coletiva desse espaço e lugar.

Published: May 2019

Chronic hepatitis C virus (HCV) is a risk factor for type 2 diabetes. In the era of interferon-based HCV therapy, type 2 diabetes was associated with decreased likelihood of sustained virologic response (SVR). Preliminary studies suggest that type 2 diabetes may not reduce the efficacy of regimens involving direct-acting antiviral (DAA) medications. We aimed to determine whether preexisting type 2 diabetes is associated with a reduced rate of SVR achieved 12 weeks after treatment of HCV with DAA-based regimens.
Microstructure evolution during selective laser melting of metallic materials: A review
Authors: Zhang Xing , Yocom Christopher J. , Mao Bo , Liao Yiliang
Published: May 2019

Selective laser melting (SLM) is an additive manufacturing technology that uses a laser beam to melt powder materials together layer by layer for solid part fabrication. Due to its superior rapid prototyping capability of three-dimensional structures, SLM has been used for widespread industrial applications including aerospace, automotive, electronics, and biomedical devices. As a state-of-the-art technology, ongoing investigations are being conducted to improve the efficiency and effectiveness of SLM. In particular, understanding of microstructure evolution during SLM is essential to achieve improved process control and ensure the performance of laser-fabricated components. This paper is to review the recent research and development progress in SLM of metallic materials with a focus on the process–microstructure relationship. The grain growth and porosity evolution as affected by laser processing parameters in the SLM process are discussed. Phase transformation in SLM of steel and titanium alloys is studied. The formation of precipitates in SLM of titanium, nickel, and aluminum/magnesium alloys is reviewed. The balling phenomenon and cracking behaviors during SLM are discussed. In addition, the recent development of computational modeling of microstructure evolution during SLM is investigated.

TEKNOLOGI TERAPAN PENGHALAU BURUNG OTOMATIS BAGI PETANI PADI DI SALINGKA KAMPUS UNIVERSITAS ANDALAS
Authors: Lina Eka Candra , Zaini Zaini , Puspita Yesi
Published: June 2019

Sumatera Barat merupakan provinsi yang penduduknya rata-rata bekerja sebagai petani. Produksi padi di Sumatera Barat cukup tinggi, mencapai 55.532 ton per tahunnya. Namun, petani mengalami kesulitan dalam mengahadapi serangan hama, salah satunya yaitu hama burung. Hama burung menyebabkan kehilangan hasil mencapai 30% bahkan 100% pada tingkat serangan yang parah, dan pada tanaman serelia lainnya mampu memnyebabkan kehilangan hasil mencapai 67%. Akibat kehilangan hasil yang cukup tinggi, perlu dilakukannya pengendalian terhadap hama burung. Tetapi, pengendalian hama burung tidak sama dengan hama lain yang dapat dikendalikan secara praktis menggunakan pestisida karena hama burung yang bersifat mobile atau aktif bergerak. Saat ini petani masih menggunakan pengendalian secara mekanis yang di Sumatera disebut dengan istilah ‘Manggaro’. Dimana petani menunggui sawah dan ladangnya selama fase pengisian bulir hingga panen. Pengendalian seacara mekanis ini menghabiskan waktu petani untuk menghalau kedatangan hama burung.

Berdasarkan permasalahan tersebut, maka dibutuhkan suatu usaha dan teknologi yang mampu digunakan untuk menghalau burung tanpa perlu diawasi oleh petani, hemat waktu dan lebih efisien dalam pengendalian serta dapat digunakan dalam jangka panjang. Kegiatan penelitian yang diusulkan meliputi pemasangan alat penghalau burung otomatis dengan sistem deteksi panas tubuh dan motor pengayun sumber bunyi di lahan sawah yang berada disalingka kampus Unand Limau Manis. Pengamatan yang dilakukan adalah hasil produksi padi terhadap 3 perlakuan yang diberikan yaitu penggunaan alat penghalau otomatis hama burung, penggunaan jaring burung dan lahan tanpa menggunakan alat atau dsebut juga sebagai kontrol. Selanjutnya,data yang diperoleh akan dianalisis untuk melihat efektivitas alat penghalau hama burung otomatis. Manfaat alat ini dapat membantu petani dalam pengendalian hama burung. Dimana petani tidak harus berada dilahan persawahannya seharian penuh untuk menghalau hama burung yang menyerang lahan persawahan tersebut.

Perancangan Alat Penyambung Universal pada Transporter Mini Tandan Buah Segar Kelapa Sawit
Authors: Arkeman Arlimda
Published: June 2019

Every palm oil plantation has different characteristics. In Indonesia, some of the palm oil plantations are unique because of its peaty, muddy, and bumpy features. Today, the existing Fresh Fruit Bunch (FFB) transport equipment is rigid and unable to follow the contour of outline of plantation ground, which limits its mobility. Therefore, it is necessary to design FFB transport equipment that offers ease of mobility. The new design has a universal joint feature that connects the front of part of the equipment (driver section) with the load carrier part (rear part). The design includes three-dimensional images with its simulations, two-dimensional images and the strength analysis of the joint. Both design drawings and strength analysis are carried out using SolidWorks engineering software. The result is a design of a universal joint with a dimension of 0.2 m in length and 0.15 m in width, and is capable of rotating in two directions; each at 30 degree on Y axis and 16 degree on X axis. All components of the universal joint are SS400 steel which has a tensile strength of 250 MPa. Calculation of strength with a tensile load of 1 ton results in a safety factor of 833. This safety factor ensures the maximum life span and strength of the universal joint.

Fatty Acid Fueled Transmembrane Chloride Transport
Authors: N.W. Howe Ethan , Gale Philip
Published: June 2019

We report an example of the use of fatty acids to drive chloride transport by creating a pH gradient across a vesicular lipid bilayer membrane. Addition of an unselective squaramide-based chloride transporter (which transports both H+and Cl-) facilitates the transport of HCl from the vesicle (driven by the pH gradient) so creating a chloride gradient. Addition of further aliquots of fatty acid ‘fuel’ can initiate further transport of chloride out of the vesicle by re-establishing the pH gradient. This is an example of a prototypical chloride pumping system.

Hierarchical molecular assembly directed by cell-regulated aqueous solvent is a fundamental strategy for manufacturing various proteinaceous structures that are of intense interest for nanotechnology, sustainable manufacturing and regenerative medicine. However, to translate the natural strategy into advanced digital manufacturing like three-dimensional (3D) printing remains a tremendous technical and theoretical challenge. This work presents a 3D printing technique of a particular protein, silk fibroin, by rationally designing an de novo aqueous salt bath capable of directing the hierarchical assembly of the protein molecules. This technique, conducted under aqueous and ambient conditions, results in 3D proteinaceous architectures characterized by intrinsic biocompatibility/biodegradability and remarkable mechanical performance. The versatility of this method is shown in a diversity of 3D shapes and a range of functional components integrated into the 3D prints. Exceptional manufacturing capability and one promising application is exemplified by the single-step construction of perfusable microfluidic chips, also an analogy of small-diameter vascular grafts, which eliminates the use of supporting or sacrificial materials owing to optimized crosslinking dynamics and compartmentalized printing parameters. The 3D shaping capability of the protein material can benefit a multitude of biomedical devices, from drug delivery to surgical implants to tissue scaffolds.

A avaliação de políticas sociais no contexto da reforma gerencial do Estado:
Authors: Moreira Marcelo , Fernandes Fernando , Sucena Luiz Fernando
Published: June 2019

O debate sobre avaliação de políticas sociais deveria procurar dimensioná-la histórica e politicamente no processo de reforma gerencial do Estado brasileiro, criticando a ascendência de seu entendimento como elemento como elemento eminentemente técnico da gestão. Por este raciocínio, os objetivos da avaliação caminhariam para a resolução de determinados problemas da gestão que recorre à informação científica para subsidiar com a "razão" suas escolhas. Em essência, tal postura não seria prejudicial à população, mas isso ocorre à medida que a gestão encara que, primeiro, é necessário determinar padrões de articulação entre formuladores, implementadores e executores; depois, que é preciso pautar suas ações por indicadores e práticas de eficiência, eficácia e efetividade, abandonando a equidade; só então, com este desenho metodológico definido, é que aborda as demandas do cidadão, manietado ao papel desprestigiado de usário, beneficário, cliente ou consumidor. O presente artigo visa redefinir esse caminho, tendo como concepção teórica fundante e permanente interação e a não-autonomia do econômico sobre social e político, o que deve refletir diretamentente na atuação dos pesquisadores/avaliadores, na sociedade civil organizada e na gestão pública. Para tanto, propõe-se uma análise metodológica que contempla a interação teoria-prática e concebe os desejos, anseios e demandas dos destinatários na políticas sociais como cerne da práxis avaliativa.

Nesta pesquisa são analisadas as interfaces entre a família e as políticas sociais no Brasil, na perspectiva de gênero. São apresentados diversos dados sobre a estrutura familiar e o trabalho das mulheres. Focaliza-se, principalmente, a questão da maior sobrecarga feminina referente ao cuidado dos dependentes, considerando-se a existência de um déficit nos serviços relacionados às necessidades da reprodução familiar oferecidos pelo poder público. Ao se identificar as novas tendências na constituição das relações de gênero e nas ações do Estado, caracterizando especialmente a situação na área da educação e da saúde, objetiva-se contribuir para a reflexão das determinações sociais do bem-estar das famílias. Destaca-se, ademais, a importância da participação das mulheres na construção de uma divisão sexual do trabalho mais equitativa, na qual a dominação masculina, os estereótipos e discriminações de gênero sejam cada vez mais reduzidos, tanto no espaço público quanto na esfera doméstica.
The Role of ICT in Addressing Corruption Across Political Regimes
Authors: Dyussenov Mergen
Published: May 2019

The paper reviews existing literature on the role of the internet in addressing corruption by breaking it down into instrumental, important, and critical roles, across two types of political regimes – (semi-)authoritarian and democracies. It analyzes the key resources and strategies utilized by governments and activists across these regimes, and looks into the common themes that emerge as a result of analyzing literature sources, i.e. the notion of crisis, lack of a single accepted definition of corruption across nations, factors found to positively correlate with reduced corruption, and the evolving nature of the internet. The paper finds that neither regime can be perfectly immune against mass-scale protests caused by dissatisfaction with worsening corruption. However, the regimes differ in the nature of protests, with semi-authoritarian regimes witnessing more violent and aggressive uprisings fueled by long-accumulated social disappointment with previous repressive regimes than across much of democracies.

Authors: Piano A.M.P. , Castillo-Israel K.A.T.
Published: June 2019

The study aimed to evaluate the physico-chemical quality and microbial safety of ready-to
-eat fresh-cut watermelon and pineapple sold in selected wet markets and supermarkets in
Imus, Cavite. These two fruits are the top-selling fresh-cut fruits in the area based on a
prior survey conducted. Higher water soaking scores were obtained from fresh-cut fruits in
wet markets while lower visual quality scores were obtained from wet market samples
compared with those from supermarkets. Comparing fresh-cuts from whole fruits, lower
vitamin C content was observed on fresh-cut samples than whole fruit samples. For Total
plate count of fresh-cut watermelons, no sample exceeded the maximum tolerance level
(107 CFU/mL) for the production day for the supermarket samples while 3 out of 6
samples from the wet markets had exceeding levels. For pineapple, the number of samples
which exceeded the tolerance levels were 4 out of 6 from supermarkets and 3 out of 6
from wet markets. For yeast and molds count, (maximum tolerance level is 104
), all
watermelon samples did not have exceeding levels while 5 out of 6 samples both from
supermarkets and wet markets had exceeding levels. For Total coliforms, maximum
tolerance is 102
. All watermelon samples exceeded this level. For pineapple, all from
supermarkets and 3 out of 6 samples from wet markets exceeded the levels. All fresh-cut
pineapple and watermelon samples were negative for Escherichia coli. For watermelon, 2
samples each from supermarkets and wet markets were positive for Salmonella while for
pineapple, 1 sample from the supermarket and 3 from wet markets turned out positive.
Impact of Corporate Reputation on Firm Risk: An Analysis of Pakistan Stock Exchange Listed and PACRA Rated Firms
Authors: Bakhsh Allah , Akhtar Muhammad Hanif , Akhtar Adeel
Published: May 2019

This study has examined the impact of corporate reputation on risk exposure of the firms listed at Pakistan Stock Exchange (PSX) and rated by Pakistan Credit Rating Agency (PACRA). It has employed firm’s credit ratings as a proxy for corporate reputation. It has covered the time period from 2007-2016 and unbalanced and undated panel regression analysis has been carried out to observe the significance of the relationship among corporate reputation and the firm risk i.e. total risk and its parts (systematic and unsystematic risk). It has been found that corporate reputation has a significant negative relationship with total risk and systematic risk of the firm. It is however found that corporate reputation is insignificant in explaining the unsystematic risk of the firms. Leverage and profitability (the control variables) are also found significant in explaining the risk exposures of the firms.
