Shared Memory Architecture for Simulating Sediment-Fluid Flow by OpenMP
Authors: Gunawan Putu Harry , Utomo Ardhito
Published: May 2019

Simulation of fluid flow using Shallow water equations (SWE) and sediment movement below it using Exner equation is given. Both of the equations will be combined using splitting technique, in which SWE would be computed using Harten-Lax-van Leer and Einfeldt (HLLE) numerical flux, then Exner would be computed semi-implicitly. This paper elaborates the steps of constructing SWE-Exner model. To show the agreement of the scheme, two problems will be elaborated: (1) comparison between analytical solution and numerical solution, and (2) parallelism using OpenMP for Transcritical over a granular bump. The first problem is going to tell the discrete $L^{1}$-, $L^{2}$-, and $L^{\infty}$-norm error of the scheme, and the second one will show the simulation result, speedup, and efficiency of the scheme, which is around $56.44\%$.

A bacia hidrográfica do rio Caldas possui área de drenagem de aproximadamente 1.288,00 km², abrange onze municípios e seu curso d’água principal é afluente do rio Meia-Ponte, um dos mananciais que abastecem Goiânia. Objetivou-se analisar: a) os conflitos de uso do solo por atividades antrópicas na bacia hidrográfica do rio Caldas, estado de Goiás, enfatizando as ocorrências destas atividades nas Áreas de Preservação Permanente (APPs) de cursos d'água, de acordo com a Lei 12.651/2012 (Código Florestal); b) o histórico da ocupação irregular das APPs para um período de 32 anos (1985 – 2017), observando se após a aprovação do Código Florestal ainda há irregularidades no uso do solo desses locais. A metodologia consistiu na consulta a documentos legais, avaliação cartográfica e na classificação de imagens de satélites para os anos de 1985, 2008, 2012 e 2017. Constatou-se que 35,903 km² são ocupados pelas APPs amostradas neste estudo, aproximadamente 2,8% da área da bacia. Para o ano de 1985 quantificou-se uma área de 30,93 km² de conflitos de uso do solo nas APPs, passando para 19,9 km² em 2008, 22,67 km² em 2012 e 17,18 km² em 2017. Pastagem foi a classe que mais ocupou áreas nas APPs em todos os anos avaliados. As alterações ocorridas na legislação após 1985 influenciaram na redução da ocupação das APPs, porém, em 2017 mais de 47% dessas áreas ainda são ocupadas ilegalmente. Os resultados mostram que as APPs estudadas sofreram intervenções antrópicas durante todo o período analisado, evidenciando o não cumprimento da legislação ambiental federal.

Testosterone Replacement Therapy Has Limited Effect on Increasing Bone Mass Density in Older Men: a Meta-analysis
Authors: Junjie Wang , Dongsheng Hao , Lei Sun , Hongzhuo Li , Changying Sun
Published: May 2019

Background:

Testosterone insufficiency may play a role in age-related decreases in bone mass density (BMD) and osteoporosis in aging men. Testosterone replacement therapy (T therapy) seems to be a simple and convenient way to increase BMD and improve the condition of osteoporosis.

Objective:

To evaluate the effects of T therapy in increasing BMD among older men with low serum testosterone concentrations.

Methods:

A comprehensive search in the PubMed, EMBASE, Web of Science and Cochrane Central databases was undertaken for randomized controlled trials (RCTs) on the effect of T therapy on osteoporosis in aging men. Primary outcome measures were the change in BMD, bone turnover markers, prostate symptoms, body composition, metabolic and endocrine system markers. The final search was performed in October 2018.

Results:

Seven RCTs were included. A total of 800 patients met the inclusion criteria. T therapy did not significantly reverse the trend toward decreasing BMD in the spine, femoral neck, Ward’s triangle and the whole body, with the exception of the trochanter and total hip. In addition, T therapy increased prostate size, lean mass, sex hormone levels; reduced HDL concentration; and had no statistical effect on prostate symptoms, body composition, serum hormones and metabolism.

Conclusion:

T therapy is not effective in increasing BMD in older men. In addition, it has limited effects on prostate-specific antigen (PSA), the International Prostate Symptom Score (IPSS), body mass index (BMI), fat mass, parathyroid hormone (PTH), 25-VitD and lipid metabolism, although it can increase prostate size, lean mass, and sex hormone levels, and reduce glucose levels and HDL concentrations.

Published: May 2019

Background:

Griseofulvin - a mold metabolite produced by Penisilium griseofulvum is known as an antifungal drug.

Objective:

Thus, the goal of this paper is the design and synthesis of new griseofulvin derivatives and evaluation of their antifungal activity.

Methods:

Forty-two new compounds were synthesized using classical methods of organic synthesis and evaluated for their antimicrobial activity by microdilution method.

Results:

All forty-two new compounds exhibited very good activity against eight tested micromycetes with MIC ranging from 0.0075-0.055 mg/ml and MFC from 0.02-024 mg/ml. All compounds exhibited better activity than reference drugs ketoconazole (7-42 times) and bifonazole (3-16 fold). The most promising was compound 15. The most sensitive fungal was found to be T. viride, while the most resistant, as was expected, was A. fumigatus. It should be mentioned that most of compounds exhibited better activity than griseofulvin.

:

The molecular docking studies revealed that the most active compound have the same hydrophobic and H-bonding interactions with Thr276 residue observed for griseofulvin forming 3 hydrogen bonds while griseofulvin only one. In general, the molecular docking results coincide with experimental.

Conclusion:

Forty-two giseofulvin derivatives were designed, synthesized and evaluated for antimicrobial activity. These derivatives revealed good antifungal activity, better than reference drugs ketoconazole, bifonazole, and griseofulvin as well.

An analysis of plasma dynamic processes and shock waves interactions in supersonic jet at plasma spherical formation initiation was made using the high-speed digital image recording. The dynamics of the spherical plasmoid which creates discontinuities, affecting the bow shock wave in front of the model was investigated with a high temporal resolution. It was shown that during the time of plasmoid electric current (about 100-130 microseconds) the structure of supersonic flow around the model changes: the shock layer is transformed, bow shock wave detached distance on the symmetry axis is significantly increased due to a change of oncoming flow parameters and structure.

AbstractThe crystalline structure of intermetallic Cu_3Sn synthesized by successively condensing thin layers of copper and tin on a substrate at 150°C has been studied. Cu_3Sn compound exists in a very narrow homogeneity range and has a long-period close-packed ordered D0_19 superstructure. It has been found that the crystal lattice exhibits many slip traces associated with dislocation motion. The dislocation motion is due to the stressed state of the crystal, which can be characterized as uniform extension. Electron micrographs show that slip traces in the Cu_3Sn crystal are parallel to the ( $$\bar {1}\bar {1}21$$ ) and ( $$11\bar {2}1$$ ) planes belonging to pyramidal slip system II, which is a main slip system along with pyramidal and basal ones. Slip traces result from the motion of partial dislocations, as indicated by the amount of slip, which is equal to half the interplanar distance. Since the crystal is ordered, slip is accomplished by a pair of superpartial dislocations and a slip trace may be a superstructural or complex stacking fault.

AbstractVariations of the morphology and field-emission properties of surface-structured n - and p -type silicon wafers have been studied. The silicon surface has been structured by etching in a fluorine–carbon plasma and depositing subnanodimensional island carbon masks. It has been shown that surface structuring in a fluorine–carbon plasma makes it possible to reach desired field-emission currents in electric fields of different strengths. Physicochemical models of field emission mechanisms and models of destruction of surface-modified multipoint silicon array cathodes have been considered.

The formation of non-covalent electrostatic complexes based on the water-soluble fullerene derivative (WSFD) and chlorin e6, dissolved in water or in ethanol was showed by absorption and fluorescent spectroscopy methods. As a result of the formation of such complexes, the chlorine e6 absorption spectrum changed with a bathochromic shift and its fluorescence was effectively quenched. The Stern-Volmer constants of complex are 7.3·10^5 and 2·10^5 M^-1 in water and ethanol, respectively. It was found that complex consists of 1 molecule of WSFD and 3 dye molecules in aqueous solution, while in ethanol this ratio is 1:1.

AbstractLight scattering in water and aqueous solutions of NaCl and glucose under the action of a magnetic field with an induction of 0.43 mT is studied. It is established that the magnetic field does not affect the light scattering in water and aqueous solution of NaCl. For an aqueous glucose solution, the switching on of a field leads to the appearance of large fluctuations in the scattering intensity. It has been shown that these fluctuations are due to turbulization of the solution that is caused by the magnetic field.

An Internet-Based Cognitive Behavioral Therapy Program Adapted to Patients With Cardiovascular Disease and Depression: Randomized Controlled Trial (Preprint)
Authors: Johansson Peter , Westas Mats , Andersson Gerhard , Alehagen Urban , Broström Anders , Jaarsma Tiny , Mourad Ghassan , Lundgren Johan
Published: May 2019

BACKGROUND

Depression is a common cause of reduced well-being and prognosis in patients with cardiovascular disease (CVD). However, there is a lack of effective intervention strategies targeting depression.

OBJECTIVE

The study aimed to evaluate the effects of a nurse-delivered and adapted internet-based cognitive behavioral therapy (iCBT) program aimed at reducing depression in patients with CVD.

METHODS

A randomized controlled trial was conducted. A total of 144 patients with CVD with at least mild depression (Patient Health Questionnaire–9 [PHQ-9] score ≥5) were randomized 1:1 to a 9-week program of iCBT (n=72) or an active control participating in a Web-based discussion forum (online discussion forum [ODF], n=72). The iCBT program, which included 7 modules, was adapted to fit patients with CVD. Nurses with an experience of CVD care provided feedback and a short introduction to cognitive behavioral therapy. The primary outcome, depression, was measured using PHQ-9. Secondary outcomes were depression measured using the Montgomery-Åsberg Depression Rating Scale–self-rating version (MADRS-S), health-related quality of life (HRQoL) measured using Short Form 12 (SF-12) survey and EuroQol Visual Analogue Scale (EQ-VAS), and the level of adherence. An intention-to-treat analysis with multiple imputations was used. Between-group differences in the primary and secondary outcomes were determined by the analysis of covariance, and a sensitivity analysis was performed using mixed models.

RESULTS

Compared with ODF, iCBT had a significant and moderate treatment effect on the primary outcome depression (ie, PHQ-9; mean group difference=−2.34 [95% CI −3.58 to −1.10], P<.001, Cohen d=0.62). In the secondary outcomes, compared with ODF, iCBT had a significant and large effect on depression (ie, MADRS-S; P<.001, Cohen d=0.86) and a significant and moderate effect on the mental component scale of the SF-12 (P<.001, Cohen d=0.66) and the EQ-VAS (P<.001, Cohen d=0.62). Overall, 60% (n=43) of the iCBT group completed all 7 modules, whereas 82% (n=59) completed at least half of the modules. No patients were discontinued from the study owing to a high risk of suicide or deterioration in depression.

CONCLUSIONS

Nurse-delivered iCBT can reduce depression and improve HRQoL in patients with CVD, enabling treatment for depression in their own homes and at their preferred time.

Published: May 2019

The purpose of this study is to determine the symbol sense and structure of mathematical sense in terms of students' ability to solve algebraic problems or other mathematical problems that require symbol expression or structure. Difficulties experienced by students in solving mathematical or algebraic problems may be due to the ability of symbol sense and low structure sense or didactic design that the teacher conveyed is not in accordance with the category of symbols and structure sense that students have. A student with good symbols and structure sense is able to appreciate the power of symbols, knowing when to use the right symbols and being able to manipulate and understand symbols in various contexts. The method used in the study used a qualitative descriptive method. The population of this study was seventh grade students of the Islamic junior high school, the instruments used were symbol and structure sense tests, questionnaires, and interview forms. The results of the study indicate that the ability of symbol sense and student structure sense is still low because of a lack of conceptual knowledge and algebraic manipulation, for this reason it is necessary to have an appropriate learning model to improve both of these abilities.

This exposition is centred around a video essay, which uses some parts of Animal Years, a series of one-year performance-projects recorded on Harakka Island in the years 2002-2014, as examples to create a form of "digital autotopography". Returning to the site of the performance Year of the Rooster (2006) and Christmas of the Rooster - Tomten (2006) twelve years later serves as a starting point for reflections on the materiality of the site, on the birches growing there as co-performers, and on revisiting and assembling old works as way of doing things with performance.
Strategies of Fiction
Authors: Stephen Bain
Published: May 2019

Fictional Worlds as Structures for Public Space Performance is an exposition that fractures into multiple parts, text, performance, spatial design, and creative writing. Fiction is seen as a device for creating shared experience, a familiar process in the performing arts but also observed in the public domain of politics, where a key example is taken to discuss the dynamics of how fiction may be both symbol and action. Relating aesthetics to politics through fiction as a method, a collective influence is confirmed by the event.
Fiction is split into various strategies in a poetic reflection on archetypes of space, proposed as 8 distinct fiction-types that open the way for common understanding. Using the format of a screenplay, 8 types are fleshed out and supported by reflections on influential international artworks and theories. Finally these types are used as a tool to analyse my own public space performance experiments in Auckland, New Zealand.
The experience of ‘something’ in performance
Authors: Tero Nauha
Published: May 2019

This paper regards the notion of ‘something’ in the context of performance and performative speech-acts. ‘Something’ is a crisis, an element of systemic cycles: it distorts both as a signal and terminal crisis for any system or standards of thought or practice. My aim is to consider this crisis in loose connection with performativity, economy, and philosophy – or through a broad articulation of ‘performance with something’. We can question why there is a notion of experiencing ‘something’, which does not signify anything but only ‘something.’ Is ‘something’ something else when the quotation marks are left out, when ‘something’ or “something” becomes something? Is something then the act of becoming, eluding us as it moves, escaping its inverted commas? Many concepts can be used to approach this issue, such as Gilles Deleuze’s construction of the terms ‘aliquid’ and ‘sense’. We can regard how decisionality, the term that François Laruelle has proposed as a decisive element for all philosophical inquiries, might cut off something and slice it into pieces. Or we can consider whether something is simply gnosis, an expression of the mystical and mystifying experience of the Gnostics – an approach that recognizes our epoch’s search for a correlation with the paranormal. Still, is something the thing-in-itself, which we may not ever possess except as a correlation with consciousness? We might even ask if something is the foreclosed Real, something that cannot be captured with a noun, something that cannot, in the nature of things – the nature of somethings – be captured at all.

Evaluation of approximate comparison methods on Bloom filters for probabilistic linkage
Authors: Brown Adrian P , Randall Sean M , Boyd James H , Ferrante Anna M
Published: May 2019

Introduction The need for increased privacy protection in data linkage has driven the development of privacy-preserving record linkage (PPRL) techniques. A popular technique using Bloom filters with cryptographic analyses, modifications, and hashing variations to optimise privacy has been the focus of much research in this area. With few applications of Bloom filters within a probabilistic framework, there is limited information on whether approximate matches between Bloom filtered fields can improve linkage quality.

Objectives In this study, we evaluate the effectiveness of three approximate comparison methods for Bloom filters within the context of the Fellegi-Sunter model of recording linkage: Sørensen–Dice coefficient, Jaccard similarity and Hamming distance.

Methods Using synthetic datasets with introduced errors to simulate datasets with a range of data quality and a large real-world administrative health dataset, the research estimated partial weight curves for converting similarity scores (for each approximate comparison method) to partial weights at both field and dataset level. Deduplication linkages were run on each dataset using these partial weight curves. This was to compare the resulting quality of the approximate comparison techniques with linkages using simple cut-off similarity values and only exact matching.

Results Linkages using approximate comparisons produced significantly better quality results than those using exact comparisons only. Field level partial weight curves for a specific dataset produced the best quality results. The Sørensen-Dice coefficient and Jaccard similarity produced the most consistent results across a spectrum of synthetic and real-world datasets.

Conclusion The use of Bloom filter similarity comparisons for probabilistic record linkage can produce linkage quality results which are comparable to Jaro-Winkler string similarities with unencrypted linkages. Probabilistic linkages using Bloom filters benefit significantly from the use of similarity comparisons, with partial weight curves producing the best results, even when not optimised for that particular dataset.
Tourism and terrorism The determinants of destination resilience and the implications for destination image
Authors: Benjamin Cassiopée , Lapointe Dominic , Sarrasin Bruno
Published: May 2019

Safety is essential in order for a destination to maintain and increase tourism activities (Gupta et al., 2010; Hall et al., 2004). In comparison, terrorist attacks are more likely to have negative effects on tourism than natural disasters (Sönmez et al., 1999). During the last decades, several terrorist acts have been committed in touristic cities of the North and South (including Boston, Istanbul, Manchester, New Delhi, New York, Paris, and Tunis). Security concerns and the threat of violence perpetrated by certain groups with radical political and religious demands do not only affect a destination’s image and reputation and individual decisions about whether to visit a given destination. They also influence the political and economic balance, which in turn affects the environment in which the tourism industry operates (Hall et al., 2004). While some destinations appear to be suffering the long-term consequences of terrorist attacks on their tourism industry (Liu and Pratt, 2017), others are successfully keeping their industry afloat and avoiding significant economic downturns (Gurtner, 2007; Putra and Hitchcock, 2006). We are therefore seeking to understand the reasons why some destinations manage to maintain their image and remain attractive to tourists despite terrorist acts and others struggle to overcome the consequences of such acts on their industry, even years after the fact.
Managing the reputation of cruise lines in times of crisis A review of current practices
Authors: Liu-Lastres Bingjie , Johnson Amy M
Published: May 2019

Serving as both a luxury hotel and a traveling city, the cruise line industry acts as one of the fastest growing sectors within the tourism and hospitality industry. With a 62% growth in demand from 2005 to 2015, the cruise line industry expects to welcome 28 million global passengers on board (Cruise Line International Association [CLIA], 2018). According to CLIA (2018), the top five source markets of the global cruise industry are the United States (11.5 million passengers in 2016), China (2.1 million passengers in 2016), Germany (2 million passengers in 2016), United Kingdom (1.9 million passengers in 2016), and Australia (1.3 million passengers in 2016). Although the United States ranks as one of the most important markets for the cruise industry, the number of domestic cruise line companies remains relatively small, which is due to the necessity of obtaining substantial capital investment, and the intense competition (Ryschka et al., 2016). Within such a competitive market, reputation has become one of the key assets that cruise line companies cannot simply overlook (Weaver, 2005). Reputation refers to “the prestige or status of a product of service, as perceived by the purchaser, based on the image of the supplier” (Petrick, 2002:125). Reputation helps distinguish a particular brand from others as well as affecting peoples’ attitude, perceptions, and purchasing intentions (Petrick 2002, 2011; Weaver, 2005). The strong relationship between reputation and consumer decisions and behaviors has been well reported by numerous empirical studies, including both the general marketing literature (e.g. Olshavsky & Granbois, 1979) and the cruise tourism literature (e.g. Perick, 2002, 2011).
Theoretical foundations for the study of image and reputational management in tourism and hospitality
Authors: Walters Gabby , Mair Judith
Published: May 2019

Risk and reputation recovery in tourism should not be viewed as independent or isolated from other discipline areas. Frameworks, processes and theories cited in studies that explore tourism crisis recovery often include those from service recovery, public relations (PR) and communication, marketing, branding and consumer psychology. Many of the contributed case studies in this book demonstrate the use and application of these concepts, all of which are introduced and explored in this chapter. This chapter is organised into five sections. First, an understanding of the psychology behind consumer behaviour in times of crises is important to organisations and destinations seeking to maintain or recover their reputation. This chapter then begins by exploring the consumer behaviour concepts commonly employed by those seeking to better understand the impact of crisis and disasters on tourist demand. Following this, the influence of the media on the formation of tourists’ image perceptions and subsequent behaviour is discussed. The next section discusses the role of marketing communications strategies and branding to the recovery process and in then we introduce the relationship between resilience and reputation and image recovery, a phenomena that features in two of our contributed cases yet remains understated in the current academic literature. The chapter concludes with a discussion on service recovery and its importance to image and reputation recovery within the tourism and hospitality sector.
Service failures as triggers of superior brand evaluations
Authors: Hutzinger Clemens , Weitzl Wolfgang
Published: May 2019

In pursuit of better purchasing decisions (e.g., choosing the right restaurant or hotel), prospective customers increasingly turn to social media, such as Facebook, to source information about new products, services and brands. On Facebook, a brand’s former, current and potential customers are not only exposed to marketer-created brand postings, but also to other customers’ subjective evaluations, personal thoughts and feelings regarding their consumption experiences (Hennig-Thurau et al., 2010). Research has shown that consumers strive for multifaceted goals when sharing consumption-related postings online. For instance, some satisfied customers want to help the company by posting favorable statements about a positive brand experiences, known as positive electronic word of mouth or PeWOM (Hennig-Thurau et al., 2004), while others want to help their fellow shoppers by giving a neutral description of a regular brand experience (ReWOM). However, many dissatisfied customers also use Facebook brand-pages as a public platform to express their unfavorable thoughts and negative emotions (e.g., anger) after a service failure by means of an online complaint or negative electronic word of mouth (NeWOM; Ward & Ostrom, 2006; Weitzl et al., 2018).
Consumers that are directly affected by the service failure and involved in the recovery process are referred to as complainants. The reasons why customers spread NeWOM are diverse. They range from venting (i.e., lessening his/her frustration and reduce anger), via revenge (i.e., intentionally sabotaging and harming the company; Grégoire et al., 2009), warning others (Willemsen et al., 2011), to advice seeking (to acquire new skills/information to better use and/or repair the product; Willemsen et al, 2013). Earlier research demonstrates that online complaints can have strong and diverse detrimental effects, particularly on a brand’s potential customers (so-called online complaint bystanders), including unfavorable attitudes and an increased willingness to criticize the involved brand to others (e.g., Chevalier & Mayzlin, 2006; Sen & Lerman, 2007). However, evidence also exists that ‘webcare’, which is company’s online complaint handling response to a public complaint can repair negative reactions of these bystanders to some extent (e.g., Weitzl & Hutzinger, 2017). It remains, nevertheless, unclear how far such positive reactions can be stimulated with webcare among NeWOM bystanders.
Rubbish and reputation How unsustainable waste management impacts tourism
Authors: Miller Rohan , Howell Gwyneth

Tourism is recognised as having a two-way relationship with the environment (Halleux, 2017). On the positive side, many tourists are attracted to destinations to experience product attributes such as cultural heritage, flora and fauna, sea and sand. Implicitly, sustainability practices and maintaining the destination’s environmental integrity are critical to this form of tourism (Ecorys, 2013). On the darker side, however, it is recognised that tourism places significant pressure on a destination’s natural environment through pollution, ecosystem degradation and additional strain on natural resources (Weston et al., 2016). Thus, many tourist destinations have reputations that are intrinsically linked to their management of the environment and potentially negative product attributes that can impact on the environment (such as garbage, waste and sewage) (Inversini et al., 2009). In this context, Fombrun et al.’s (1999:72) definition that reputation is considered as “a perceptual representation of a company’s [or destination’s] past actions and future prospects that describes the firm’s overall appeal to all of its key constituents when compared with other leading rivals” is applied in this chapter.
Reputation and perceived resilience in developing countries bidding for major sports events
Authors: Shipway Richard , Miles Lee
Published: May 2019

Increasingly, international sports events (ISEs) are viewed as attractive opportunities for developing nations seeking to enhance their global profile in terms of both global prestige, economic development, and tourism (Chappelet & Parent, 2015; Shipway & Fyall, 2012). From a resilience perspective, the dimension of changing host locations, often due to the increasingly competitive bidding agenda of many host cities and nations, represents a significant proposition that has major implications with regards to the resilience of such events, in terms of crisis and disaster management. As such, changing host locations, from a resilience perspective, requires not only attention to the capacity of sports venues and infrastructure to absorb shocks and still maintain function, but to also include the propensity to facilitate adaptation, renewal and even re-organisation (Shipway, 2018). Whether these are natural disasters or man-made terrorist attacks, any disturbance creates an opportunity for both undertaking new actions (innovation), and for more effectively reacting to their onset (ongoing development) (Berkes et al., 2003; Holling, 1973; Gunderson 2000). Similarly, crisis management is influential in being an assessment of the ability of the country, including its emergency services, political elite, medical services, military and disaster management system to handle emergencies and/or disasters (Shipway & Miles, 2018).
The road to recovery Reimagining Kaikoura after a natural disaster

Published: May 2019

It is widely recognized that tourist destinations are vulnerable to disruptions caused by natural disasters, and understanding tourism response and recovery to natural disasters is a critical topic of research internationally (Mair et al., 2016). Post-disaster recovery is defined as: “the development and implementation of strategies and actions to bring the destination back to a normal (pre-event) condition or an improved state” (Mair et al., 2016: 2). Recovery may commence immediately following a crisis or disaster, or can be delayed if a destination has been considerably damaged and residents and businesses profoundly affected. Scott et al. (2008) have suggested that the disaster recovery process contains three phases – recovery of damaged infrastructure, marketing responses (revolving around communication and recovery marketing), and adaptations to the new system. These phases may occur sequentially or simultaneously, with different stakeholder groups managing them (Mair et al., 2016).

Previous studies highlight the relationship between Corporate Governance and Corporate Social Responsibility. Good corporate governance has been found significantly influence the level of a company social responsibility whether in conventional or Islamic companies context. Most of the studies focus of the studies focus on conventional banks or Islamic banks belong to government or provate actors. However, limites or even none of the studies has tried to compare the impact of corporate governance on social responsibility between government and private owned syariah banks. Through quantitative method, we studied the differences between government and private owned syariah banks using six syariah banks samples. The sample was purposively selected from Indonesian Bank website. Our data analysis shows that all three variables; independent commissioners, boards of directors, and sharia supervisory boards are significantly impact the companiesâ€™ corporate social responsibility pactices. Eventhough, the difference between government and private owned syariah banks in social responsibilty practices is not significant, the result shows that the level compliance of government syariah banks towards social responsibiity is higher than private syariah banks. This might prove that government syariah banks might more commit to social welfare than private syariah banks. Future reseach with more samples and variables might be required to make the finding more valid.
