Risk Factors, Mechanisms and Treatments of Thromboangiitis Obliterans: An Overview of Recent Research
Authors: Li Meng-di , Wang Yi-fan , Yang Mei-wen , Hong Fen-fang , Yang Shu-long
Published: August 2019

Background::

Thromboangiitis obliterans (TAO) is a nonatherosclerotic thromboticocclusive vasculitis that affects the vessels of the small and medium-sized extremities. No explicit etiology or pathogenesis of TAO has been proven, and more effective treatments are needed.

Objective: :

The study aimed to summarize and present an overview of recent advances regarding the risk factors, mechanisms and treatments of TAO and to organize the related information in figures to provide a comparatively complete reference.

Methods::

We searched PubMed for English-language literature about TAO without article type limits, including articles about the risk factors, pathological mechanisms and treatments of TAO in the last 10 years with essential supplements (references over ranges and English abstracts of Russian literature).

Results::

After screening content of works of literature, 99 references were evaluated. We found that risk factors of TAO include smoking, gene factors and periodontal diseases. The underlying mechanism of TAO involves oxidative stress, immunity, hemodynamic changes, inflammation and so on. Moreover, similarities in genetic factors and cigarette relevance existed between periodontal diseases and TAO, so further study of relationship was required. For TAO treatment, medicine, endovascular intervention and revascularization surgery, autologous cell therapy and novel therapies were also mentioned. Besides, a hypothesis that infection triggers autoimmunity in TAO could be speculated, in which TLR4 plays a key role.

Conclusions::

1. A hypothesis is put forward that infections can trigger autoimmunity in TAO development, in which TLR4, as a key agent, can activate immune signaling pathways and induce autoimmune cytokines expression. 2. It is suggested to reconsider the association between periodontal diseases and TAO, as they share the same high-risk population. Controlling periodontal disease severity in TAO studies may provide new clues. 3. For TAO treatment, endovascular intervention and autologous cell therapy both showed promising long-term therapeutic effectiveness, in which autologous cell therapy is becoming more popular, although more clinical comparisons are needed.

Published: August 2019

Repurposing already approved drugs as new anticancer agents is a promising strategy considering the advantages such as low costs, low risks and less time-consumption. Disulfiram (DSF), as the first drug for antialcoholism, was approved by the U.S. Food and Drug Administration (FDA) over 60 years ago. Increasing evidence indicates that DSF has great potential for the treatment of various human cancers. Several mechanisms and targets of DSF related to cancer therapy have been proposed, including the inhibition of ubiquitin-proteasome system (UPS), cancer cell stemness and cancer metastasis, and alteration of the intracellular reactive oxygen species (ROS). This article provides a brief review about the history of the use of DSF in humans and its molecular mechanisms and targets of anticancer therapy, describes DSF delivery strategies for cancer treatment, summarizes completed and ongoing cancer clinical trials involving DSF, and offers strategies to better use DSF in cancer therapies.

Published: August 2019

Background

The frequency of occurrence of extrapulmonary tuberculosis (EPTB) has been increasing globally over the last two decades. In Morocco, EPTB cases account for 46% of the patients reported with a new episode of tuberculosis (TB). Lymph node TB (LNTB) is the most common form of EPTB. In line with the guidelines of the National TB Program, the diagnosis is mainly based on clinical evidence, including histopathology.

Objective

This study aimed to evaluate the yield of histopathology testing in the diagnosis of LNTB.

Methods

This cross-sectional, prospective study was conducted among patients with cervical lymph node who were enrolled in the study from November 2016 to May 2017 in three regions of Morocco. We compared the outcomes of histopathological testing with those of bacteriology. Sensitivity (Se), specificity (Sp), positive predictive value (PPV), and negative predictive value (NPV) of histopathology testing were calculated. Culture and Xpert tests were used as the gold standard Laboratoty Testing.

Results

A total of 262 patients were enrolled in this study. The Se, Sp, PPV, and NPV of histopathology testing were 95.6% (129/135), 64.6% (82/127), 74.1% (129/174), and 93.2% (82/88), respectively, in the presence of granuloma with or without caseous necrosis and were 84.4% (114/135), 74.8% (95/127), 78.1% (114/146), and 81.9% (95/116), respectively, in the presence of granuloma with caseous necrosis. The granuloma with caseous necrosis was associated with increased PPV and Sp of histopathology testing (P<.05).

Conclusions

The presence of the granuloma with caseous necrosis in the histopathological examination had significantly improved the yield of histopathology testing for the diagnosis of LNTB. The findings recommend to maintain histopathology testing in establishing the LNTB diagnosis and to explore other techniques to improve it.

Authors: Nowell William Benjamin , Curtis Jeffrey R , Nolot Sandra K , Curtis David , Venkatachalam Shilpa , Owensby Justin K , Poon Jiat Ling , Calvin Amy B , Kannowski Carol L , Faries Douglas E , Gavigan Kelly , Haynes Virginia S
Published: August 2019

Background

Rheumatoid arthritis (RA) is a condition with symptoms that vary over time. The typical 3- to 6-month interval between physician visits may lead to patients failing to recall or underreporting symptoms experienced during the interim. Wearable digital technology enables the regular passive collection of patients’ biometric and activity data. If it is shown to be strongly related to data captured by patient-reported outcome (PRO) measures, information collected passively from wearable digital technology could serve as an objective proxy or be complementary to patients’ subjective experience of RA symptoms.

Objective

The goal of this study is to characterize the extent to which digital measures collected from a consumer-grade smartwatch agree with measures of RA disease activity and other PROs collected via a smartphone app.

Methods

This observational study will last 6 months for each participant. We aim to recruit 250 members of the ArthritisPower registry with an RA diagnosis who will receive a smartwatch to wear for the period of the study. From the ArthritisPower mobile app on their own smartphone device, participants will be prompted to answer daily and weekly electronic PRO (ePRO) measures for the first 3 months.

Results

The study was launched in December 2018 and will require up to 18 months to complete. Study results are expected to be published by the end of 2021.

Conclusions

The completion of this study will provide important data regarding the following: (1) the relationship between passively collected digital measures related to activity, heart rate, and sleep collected from a smartwatch with ePROs related to pain, fatigue, physical function, and RA flare entered via smartphone app; (2) determine predictors of adherence with smartwatch and smartphone app technology; and (3) assess the effect of study-specific reminders on adherence with the smartwatch.

Validation of an Independent Web-Based Tool for Measuring Visual Acuity and Refractive Error (the Manifest versus Online Refractive Evaluation Trial): Prospective Open-Label Noninferiority Clinical Trial.
Authors: Wisse Robert P L , Muijzer Marc B , Cassano Francesco , Godefrooij Daniel A , Prevoo Yves F D M , Soeters Nienke
Published: August 2019

Background

Digital tools provide a unique opportunity to increase access to eye care. We developed a Web-based test that measures visual acuity and both spherical and cylindrical refractive errors. This test is Conformité Européenne marked and available on the Easee website. The purpose of this study was to compare the efficacy of this Web-based tool with traditional subjective manifest refraction in a prospective open-label noninferiority clinical trial.

Objective

The aim of this study was to evaluate the outcome of a Web-based refraction compared with a manifest refraction (golden standard).

Methods

Healthy volunteers from 18 to 40 years of age, with a refraction error between –6 and +4 diopter (D), were eligible. Each participant performed the Web-based test, and the reference test was performed by an optometrist. An absolute difference in refractive error of <0.5 D was considered noninferior. Reliability was assessed by using an intraclass correlation coefficient (ICC). Both uncorrected and corrected visual acuity were measured.

Results

A total of 200 eyes in 100 healthy volunteers were examined. The Web-based assessment of refractive error had excellent correlation with the reference test (ICC=0.92) and was considered noninferior to the reference test. Uncorrected visual acuity was similar with the Web-based test and the reference test (P=.21). Visual acuity was significantly improved using the prescription obtained by using the Web-based tool (P<.01). The Web-based test provided the best results in participants with mild myopia (ie, <3 D), with a mean difference of 0.02 (SD 0.49) D (P=.48) and yielding a corrected visual acuity of >1.0 in 90% (n=77) of participants.

Conclusions

Our results indicate that Web-based eye testing is a valid and safe method for measuring visual acuity and refractive error in healthy eyes, particularly for mild myopia. This tool can be used for screening purposes, and it is an easily accessible alternative to the subjective manifest refraction test.

Exploring an Existing Weight Management App for Use With Adolescents and Young Adults With Spina Bifida: Usability Study
Authors: Stiles-Shields Colleen , Garcia Brittney , Villota Kimberly , Wartman Elicia , Winning Adrien M , Holmbeck Grayson N
Published: August 2019

Background

Adolescents and young adults with spina bifida (AYA-SBs) have unique user needs, given their variable and complex symptom profile. Owing to multiple barriers to prevention and intervention treatments for secondary conditions (eg, obesity), AYA-SBs may benefit from the use of behavioral intervention technologies (BITs). However, as BITs are often designed and tested with typically developing individuals, it is unclear if existing BITs may be usable for AYA-SBs.

Objective

This study aimed to evaluate the usability of a high-quality, publicly available, weight management–focused mobile BIT (smartphone app) for AYA-SBs.

Methods

Overall, 28 AYA-SBs attending a Young Men’s Christian Association–based summer camp completed 4 structured usability tasks using a weight management app designed for the general public called My Diet Coach (Bending Spoons). Learnability was measured by (1) time to complete task, (2) number of user errors, and (3) correct entry of data when requested by the app. Satisfaction and general usability were measured via self-reported questionnaires and qualitative feedback following interactions with the app.

Results

The majority of the sample were able to complete the tasks, with increased completion rates and improved times on second attempts of the tasks (Ps<.05). Errors were common, and discrepancies emerged between quantitative and qualitative feedback such that self-reported measures indicated dissatisfaction but qualitative feedback was generally positive. Suggested improvements to the app included (1) tutorials, (2) simplifying the design, (3) more activity options for those who ambulate by wheelchair, and (4) notifications to prompt use.

Conclusions

AYA-SBs were able to learn how to complete specific tasks independently on a weight management app, but design changes consistent with previously proposed user needs were recommended. Rather than designing entirely new BITs, it may be possible to adapt existing technologies to personalize BITs for specific populations such as AYA-SBs.
Jathilan Horse Dance: Spirit Possesion Beliefs and Practices in The Present-day Java
Authors: Rapoport Eva
Published: August 2019

Jathilan is one of the names for traditional Javanese trance dance which takes its roots in the most archaic levels of local culture but remains very popular nowadays. It is also described as a horse dance for the horse effigies made of woven bamboo are the hallmark props used by the performers. Horse dance is a part of the folk culture, still untouched by institutionalization or commodification; it can be performed for both ritual and entertainment purposes. Trance is its main attraction, though through the lens of local beliefs it is interpreted in terms of spirit possession thus it is understood that spirits can enter performers’ bodies and fulfill their needs while being manifest in material world, but also allow the dancers to perform various feats demonstrating invulnerability to physical harm (like eating glass, walking over hot coals, being whipped or even ran over by a motorcycle).The purpose of this paper is to provide a thorough description of how trance in jathilan is performed and understood, based on existing literature, practitioners’ first-hand accounts and numerous performances observed and documented; but also to consider it in the wider context of Javanese beliefs and practices involving spirits, possession, and exorcism, which persist alongside with Islam.
History of Rakhine State and the Origin of Rohingya Muslims
Authors: Mohajan Haradhan Kumar
Published: August 2019

Myanmar is a resource-rich country especially in oil and gas. The country is involved in ethnic conflicts since its independence in 1948. Recently violation of human rights against the Rohingya Muslims become severs. The main cause of Rohingya crisis is a question about its origin. Rakhine (or Arakan) is a State located in the west coast of Myanmar. The population of Arakan State is largely agrarian and more than 43.5% live below the poverty line. The Rohingya, a Muslim ethnic minority group in Rakhine, consider as the most persecuted, vulnerable, and oppressed minorities around the globe. Recently, the persecution on Rohingya Muslims has increased due to Buddhist nationalism in Myanmar. Rohingyas are continued to suffer from several forms of restrictions and human rights violations in Myanmar due to deny Myanmar citizenship. They are victim of various oppressions, such as, arbitrary taxation, land confiscation, destruction of mosques, torture and ill-treatment, extrajudicial executions, restrictions on movements, forced eviction and house destruction, forced laborers on roads and at military camps, and financial restrictions on marriage.  Oppression on Rohingya started since 1962, when General Ne Win took power of Myanmar after a coup. Since the 1970s, a number of crackdowns on the Rohingya in Rakhine have forced hundreds of thousands to flee to neighboring countries. Sever Rohingya oppression took place in 2017 and 2018. More than one million Rohingya have migrated in Kutupalong-Balukhali, and Nayapara refugee camps, respectively, in Ukhia, and Teknaaf of Cox’s Bazar district of Bangladesh. This article deals with the origin of Rohingyas and their citizenship in the Rakhine State of Myanmar.
Postcolonial Hermeneutics: Concepts and Contribution to Understanding Socio-Religious Problems in Southeast Asia
Authors: Dewi Novita
Published: August 2019

Scrutiny of unequal power-relations between the “East” and the “West” in politics, culture, economy, and various aspects of life is the concern of postcolonial studies. Foucault's concept of power is central in postcolonial theory with which Edward Said is celebrated for his dismantling of Orientalist views. Postcolonial literature, likewise, has contributed to the growth and development of postcolonial criticism. The first objective of this article is to give a brief overview of different terms attached to the word “postcolonial”, i.e. postcolonial literary criticism, postcolonial literature and postcolonial theory, since these terms enrich one another theoretically. The second objective is to discuss postcolonial hermeneutics as a reading tool to examine various mundane practices in Southeast Asian postcolonial society. The purpose is to achieve a balanced, reciprocal exchange of perspectives while providing legitimacy for alternative interpretations to the hegemony shown in “Western” discourse. Citing traditional ways of conflict resolution and eco-friendly land management as examples, this article concludes that postcolonial reading may shed light on how socio-religious conflicts, hybrid experiences of faiths, and other social practices operate and get their respective meanings in postcolonial countries across Southeast Asia.
Secularism and Religious Nationalism: A Historical Study of Ethnic Conflict in Myanmar
Authors: Thang Ram Hlei
Published: August 2019

Myanmar, also known as Burma, has been plagued by ethnic conflict and civil war for decades since its independence in 1948. Applying historical method, this study examines the relationship between the issue of secularism and ethnic conflict in the country by focusing on the rise of religious nationalisms. This study finds that the rise of Buddhist nationalism among Burmese majority, as well as the rise of Christian nationalism among minority ethnics-have challenged peaceful coexistence  and vision of a secular state as aspirated by Burmese founding fathers. This study argues that this failure to adopt the principles of secularism was the root cause of ethnic conflict that has raged the country for over six decades.
A Relation Shaped by Geopolitical Ambitions: The United States and Cambodia during the Cold War
Authors: Neak Vibol
Published: August 2019

The diplomatic relation between the United States and Cambodia began during the Cold War, before Cambodia achieved independence from France in 1953. This article  examines the political constellation between the two states during the Cold War. The United States had been an ally and a firm supporter of Cambodia at certain times, while also being controversial enemies in other moments. The relationship worsened during the Cold War, and the two countries had gone from allies to enemies. It could be argued that the relationship deteriorated due to several reasons: the US’ foreign policy, which was crafted to contain communism, Cambodia’s failure to be truly neutral as it was often biased to the communist bloc, and the impact of third-party states.
Illustrating Political Discourse: Comics and the Rohingya Refugee Crisis
Authors: Manaysay Ferth Vandensteen
Published: August 2019

This article explores the possibility of examining a storytelling platform, which has largely been ignored by scholars of visual politics about Southeast Asia: comics. It particularly describes how comics can serve as a discursive mechanism for visual representation within the purview of the Rohingya refugee crisis in the region. Drawing from post-structuralism and visual discourse analysis as the theoretical and methodological basis of the research, the article considers a case of a long-form online comic’s engagement withthe refugee crisis,with particular attention to the criticisms about Aung San Suu Kyi and the bloody military campaign against the Rohingya minorities in Myanmar. By specifically looking into the text-image discourses and inter-textual components of the comics, this article attempts to demonstrate that the ability of comics to “speak” politics is still dependent on international news sources and wider debates, which shape the ways in which the comic artists are able to frame their work. In this case, the use of comics as a story-telling platform, however, also suggests the agency of refugees to be portrayed as political-security actors. Although the article generally focuses on the case of the Rohingya refugee crisis, it also draws attention to the contention that scholars of Southeast Asian visual politics can most profitably engage with other regional issues by turning their attention to the dynamic role of comics as an alternative medium and source of data towards the analysis of threat construction and political-security discourse about Southeast Asia.
Remediation and Counter-Hegemony of Gender Dichotomy in Indonesian Family: Multimodal Discourse Analysis of Two Kecap Advertisements
Authors: Adiprasetio Justito , Larasati Annissa Winda
Published: August 2019

Until now hegemonic gender dichotomyin Indonesia has worked in various spheres of human life, in various social roles, even in the smallest unitof social organizations: family. The dichotomy was caused by the ideology of "State Ibuism" which was disciplined during the New Order era between 1965 and 1998, where women would play the role of mothers as a subject of private work, serving various domestic needs of the family, while men play the right role conversely. Discipline works through various media formalized through the Marriage Act 1974, which explains the role of men and women in a married relationshipand Panca Dharma Wanita principles, which lays the foundation of theideal women. These ideals remained entrenched even after the New Order regime’s fall. Kecap ABC advertisements attempt to counter the hegemony over gender dichotomy and patriarchal division of work roles. This article uses Kress and Van Leeuwen’s multimodal discourse analysis to show how an attempt to counter ideologies wasmadeto be remediated through the modalities contained in these advertisements. This research elaborates on how these advertisements represent women as superior in terms of dealing with exploitation that occurs in a family, and shows how the renegotiation of domestic work is possible. This research also elaborates how the male body as a mediator of masculinity is actively mediated through modalities such as speech, gestures and moving images, by showing how men can also do domestic work.

Authors: D.C. Okafor , I.M. Agunwah , C.C. Ezegbe , C.L. Ekeoma , N.C. Onuegbu
Published: August 2019

Syrup production was done via enzyme hydrolysis. Enzymes used were crude enzymes from malted sorghum, wheat and millet and exogenous enzyme by name amyloglucosidase (AMG) which hydrolyzed Cassava (Manihot esculenta,), water yam (Dioscorea alata) and potato white (Ipomoea batatas L) starches. Syrup sugars were determined using high performance liquid chromatography (HPLC) and the sugar profile found are fructose; glucose, sucrose, maltose, D-xylose, and D-Raffinose which manifested as a result of the interaction between starches and enzymes. The sugar Fructose was in the range of 17.34 ± 0.651 g/l to 28.16 ± 0.982 g/l, Glucose sugar was in the range of 6.09 ± 0.165 g/l to 177.04 ± 1.229 g/l. The highest glucose yield (177.04 ± 1.229 g/l) was observed in Cassava starch reaction with the commercial enzyme –AMG. Sucrose content was in the range of 5.78 ± 0.180 g/l to 21.59 ± 0.536 g/l, Maltose (23.71 ± 0.125 g/l to 48.04 ± 0.125 g/l) was the most predominant sugar in all syrups gotten from the starch and crude enzymes interaction. The hydrolysis of starches using different enzyme sources yielded sugar spectra of different sugars concentrations with each starch source predisposed to the natural activity of the enzyme peculiar to their variety or cell structure. D-xylose and D-Raffinose were in the range of 0.004-0.225 g/l which is very small in quantity compared to other sugars seen while no D-stachyose was detected.

The author shares the rationale behind the assignment, the processes and strategies the students used to create the home-school literacy bags, the results of the parent satisfaction survey that was collected, and the pre-service teacher candidates’ reactions and reflections of the learning assignment.
The effect of stereotype activation on spontaneous inferences
Authors: Wang Pei , Tao Ai-hua , Gao Fan , Xie Yi-wen
Published: August 2019

We adopted the probe recognition paradigm to examine the effect of stereotype activation on spontaneous inferences among Chinese undergraduates (N = 48). First, behavioral sentences involving trait-implying behavior and corresponding situational information were simultaneously
presented. We then selected stereotype labels of the actor's behavior that were consistent or inconsistent with the behavior, and which were activated either supraliminally or subliminally. The results showed that whether a stereotype was activated supraliminally or subliminally, the influence
on spontaneous inferences was the same. Specifically, when the stereotype was inconsistent with the actor's behavior, spontaneous situational inferences were facilitated, and when the stereotype was consistent with the actor's behavior, spontaneous trait inferences were not facilitated. As
Chinese people may be more prone to spontaneous (vs. trait) inferences, this indicates that human inferences are deeply influenced by culture.
Networking and creativity: Entrepreneurial teams in high-technology startup enterprises in China
Authors: Long Jing , Wang Li
Published: August 2019

Using cross-case analysis with a survey of a large sample drawn from recently established high-technology entrepreneurial teams in China, we explored the interaction mechanism effect of the teams' internal and external networking behavior on their creativity. Results showed that external
networking behavior (such as maintaining business connections, expanding external social interaction, and participating in external professional activities) and internal networking behavior (such as increasing internal transparency) generate a positive influence on entrepreneurial teams' creativity.
Further, this influence is boosted by an interactive effect between the external and internal networking behavior of the entrepreneurial teams. Theoretical and managerial implications are discussed.
Occupational self-efficacy, organizational commitment, and work engagement
Authors: Liu Erli , Huang jiatao
Published: August 2019

We examined how occupational self-efficacy is related to organizational commitment, and how it indirectly influences work engagement. Participants were 328 part-time Master of Business Administration students in China. We used structural equation modeling and chi-square difference tests
to analyze the data and assess the proposed mediating effect. Results showed that occupational self-efficacy had a direct effect on organizational commitment and an indirect effect on work engagement through the mediator of organizational commitment. Our findings extend previous results and
show that occupational self-efficacy can be used to predict work engagement.
A meta-analysis of the relationship between occupational commitment and job performance
Authors: Wang Qiong , Jiang Yifan , Weng Qingxiong , Wang Qian
Published: August 2019

Using a random effects model, we meta-analytically estimated the true correlations between occupational commitment (OCC) and performance outcomes. We analyzed 69 empirical studies related to OCC and job performance correlations, and addressed 4 issues: First, we identified that OCC
was significantly related to task performance and overall organizational citizenship behavior. Second, we distinguished between the effects of OCC on individual and organizational citizenship behavior. Third, we identified potential moderators of the OCC–performance correlation. Finally,
we compared the predictive validity of affective organizational commitment versus OCC in predicting performance outcomes. The results support that OCC explains incremental variance in task performance and organizational citizenship behavior, which suggests that OCC should be given greater
emphasis in performance management programs.

Published: August 2019

We investigated the relationship between salespersons' internal service quality and turnover intention through the mediators of their job involvement and sales performance. To that end, we distributed surveys to salespersons in Korea and used structural equation modeling to examine
the hypotheses. The results of this study were as follows: First, internal service quality had a significant and direct impact on salespersons' job involvement and sales performance, and also their turnover intention. Second, job involvement mediated the relationship between internal service
quality and turnover intention. Third, internal service quality had a significant indirect effect on sales performance through the mediator of job involvement. Fourth, in a 2-stage mediation model internal service quality had a significant indirect relationship with turnover intention through
the mediators of job involvement and then sales performance. Theoretical and practical implications are discussed for marketing management research.

The area will be used as a Tourism Special Economic Zone (Kawasan Ekonomi Khusus). This research purpose is to find out how the feasibility of Puncak Damar and Tanjung Duriat Ecotourism as tourist destinations. The design used is qualitative with a case research approach. The result of the research showes that Puncak Damar and Tanjung Duriat have not fulfill the principle of ecotourism. Puncak Damar Ecotourism has attractions, (1) the views of Jatigede Reservoir, (2) taking pictures at viewdeck, (3) camping, (4) offroad. While in Tanjung Duriat, that are (1) the view of the Jatigede Reservoir, (2) taking photos in tree towers, (3) camping, (4) fishing, (5) boating. In terms of accessibility, the road conditions of both ecotourism are damaged and rocky and there is no public transportation. The facilities of the infrastructure in both ecotourism are not yet complete. The obstacles in Puncak Damar Ecotourism are (1) damaged road conditions, (2) no clean water, (3) no food stall that operate, (4) relations between managers. In Tanjung Duriat there obstacles are: (1) damaged road conditions, (2) no electricity system, (3) relations between managers. Both of these ecotourism are still not feasible for tourist destinations. It is because there are still many attractions that cannot support tourism activities at Puncak Damar and Tanjung Duriat Ecotourism objects.

Mengkapan Mangrove Ecotourism, located in Siak Regency, Riau Province, was once visited by a large number of visitors soon after it was opened for public in 2015. Nevertheless, since the beginning of 2016, the number of visitors has been drastically dropped. One of the causes of this unfortunate condition is that there is no established planning to guide the development of the mangrove ecotourism. Therefore, this study was aimed to formulate strategies for developing the Mengkapan Mangrove Ecotourism by using the SWOT analysis. The data was collected through conducting interviews with related stakeholders, distributing questionnaires to them, and performing field observations. The collected data was then analyzed inductively to capture the key strategy alternatives. Based on the results of SPACE Matrix and SWOT Matrix, this study formulates the following priority strategies: diversifying tourist attractions and promoting them massively by using online media, creating tour packages, and making a cooperation with travel agents.

The quality of a good or service is mostly determined by the consumers. Accordingly, satisfying consumers can be attained by providing good quality products which are not only affected by the service quality itself, but also by other factors, including price. Price issues faced by Queen Star Waterpark in Siak Regency of Riau Province in the past three years have decreased the number of visitors and raised visitors’ complaints. This study, therefore, was aimed at finding out the effect of price on visitor satisfaction. The data was collected through conducting interview with the waterpark manager and distributing questionnaires to 100 respondents as the samples chosen randomly through accidental sampling. To analyze the collected data, simple regression was used, while the hypothesis testing was performed through t-test and analysis of the coefficient of determination (R). The analysis results showed that the variable x (price) was proven to significantly affect the variable y (visitor satisfaction). This implies that the waterpark management should take this into consideration and adopt a new approach to pricing.

Authors: Putra Trisna
Published: August 2019

The popularity of village tourism, as a possibility to spend the vacation has increased in Indonesia. There are about 83.344 villages spread all around Indonesia and each of them has their own characteristic with social and culture prosperous. However there is still limited number of village being managed as a product and applied village tourism program successfully. Furthermore, the program does not seem on the right track, not focus and is poorly understood and very weak on implementation. Since the scarce availability of human resources in the village, thus the involvement of different actors and stakeholders become critical and their role as well as participations is matter. The Penta Helix of Government-Community-Business-Academics-Social Entrepreneur is a combination of stakeholder in developing tourism destination. This study applies the content analysis methodology by reviewing seven current journal articles related to village tourism development in Indonesia. This study reviews an extensive literature on village tourism study using the institutional database. Based on the reviews of the articles, this study aims in identifying the stakeholders involved in village tourism development. Furthermore, this study assessed the actor’s specific roles in village tourism development. The result of the study showed that not all tourism stakeholders as proposed by the penta helix model play significant roles in village tourism development. Most of the study on village tourism did not pay attention on the role of academician and social entrepreneur, as the community, government and business were much preferred.

Increased of the number of visitor at Gelatik Cave is a challenge in terms of cave management. In natural conditions, Caves are vulnerable with environmental changes especially microclimates condition. The change of microclimate inside the cave can destruct cave ornaments.Therefore, it is necessary to calculate the cave carrying capacity with microclimates as the main parameter. This research aims to (1) explore the daily variation of speleoclimate in Gelatik Cave Tourism and (2) analyze the cave tourism capacity in Gelatik Cave. Microclimate parameter that was measured in this research was temperature, relative humidity, and carbon dioxide inside the cave. Measurement of microlimate parameter was carried out automatically for 24 hours during peak season in December 2017 and low season in May 2018. Cave tourism capacity was measured using Lobo method (Lobo, 2015). The results showed that temperature, relative humidity, and carbon dioxide in the Gelatik Cave varry due to tourism activities. The most sensitive parameter is the carbon dioxide concentration inside the cave. The maximum of tourists allowed to visit Gelatik Cave is 76 visitors/ day during holidays and working days. Meanwhile, the maximum time of stay accepted for a particular area inside Gelatik Cave is 17 minutes 10 seconds during weekdays and 12 minutes 53 seconds during the holiday season.

The construction sector is one of the sectors that have strategic value in the national economy. Economic activity in an area is measured using the Gross Regional Domestic Product (GRDP). The development of economic activities in the construction sector can be seen from the GRDP of the construction sector. The Geographically and Temporally Weighted Regression (GTWR) model is a development of the Geographically Weighted Regression (GWR) model taking into account the diversity of locations and times. This study used secondary data, namely the data of GRDP the construction sector as a response variable and four explanatory variables, namely the number of population, local revenue, area, and the number of construction establishments. The purpose of this study is to determine the factors that influence each regency/municipality and each year observing the GRDP of the construction sector in Java with the GTWR model. GTWR model is more effective to describe the value of GRDP the construction sector of regencies/municipalities in Java Island in 2010-2016. This is indicated by the decrease in values of Root Mean Square Error (RMSE), Mean Absolute Deviation (MAD), and the Mean Absolute Percentage Error (MAPE).

One of the drawbacks of developing plants for the rehabilitation of degraded land in Indonesia is the relative lack of information about species that are suited to the local conditions. Therefore, spatial information on land degradation and the plants suitable for rehabilitation is crucial. The objectives of this study were to map the susceptibility of land to degradation and to identify some alternative species for its rehabilitation. The research was conducted in Jang Watershed, Bintan Island, Kepulauan Riau Province, Indonesia. A quick assessment of land degradation was carried out to classify the degree of land susceptibility. The land suitability evaluation was conducted manually by matching the existing biophysical condition and plant growth requirements using a geographic information system. This analysis was applied for annual plants, such as Acacia mangium, Durio zibethinus, Artocarpus champeden, Theobroma cacao and Hevea brassiliensis. Furthermore, the maps of land susceptibility to degradation and species suitability were overlaid and the result was used to provide recommendations for rehabilitating the degraded land. This study showed that 22% of the Jang Watershed area can be categorised as highly susceptible to degradation. The suitability analysis illustrated that 59% of the degraded areas were suitable for Acacia mangium. The planting of fast-growing species such as Acacia mangium is expected to improve the physical, chemical and biological properties of the soil.
