Co-Designing a Real-Time Classroom Orchestration Tool to Support Teacher–AI Complementarity
Authors: Holstein Kenneth , McLaren Bruce M. , Aleven Vincent
Published: August 2019

Involving stakeholders throughout the creation of new educational technologies can help ensure their usefulness and usability in real-world contexts. However, given the complexity of learning analytics (LA) systems, it can be challenging to meaningfully involve non-technical stakeholders throughout their design and development. This article reports on the iterative co-design, development, and classroom evaluation of Konscia, a wearable, real-time awareness tool for teachers working in AI-enhanced K-12 classrooms. In the process, we argue that the co-design of LA systems requires new kinds of prototyping methods. We introduce one of our own prototyping methods, REs, to address unique challenges of co-prototyping LA tools. This work presents the first end-to-end demonstration of how non-technical stakeholders can participate throughout the whole design process for a complex LA system—from early generative phases to the selection and tuning of analytics to evaluation in real-world contexts. We conclude by providing methodological recommendations for future LA co-design efforts.
Teaching with Analytics: Towards a Situated Model of Instructional Decision-Making
Authors: Wise Alyssa Friend , Jung Yeonji
Published: August 2019

The process of using analytic data to inform instructional decision-making is acknowledged to be complex; however, details of how it occurs in authentic teaching contexts have not been fully unpacked. This study investigated five university instructors’ use of a learning analytics dashboard to inform their teaching. The existing literature was synthesized to create a template for inquiry that guided interviews, and inductive qualitative analysis was used to identify salient emergent themes in how instructors 1) asked questions, 2) interpreted data, 3) took action, and 4) checked impact. Findings showed that instructors did not always come to analytics use with specific questions, but rather with general areas of curiosity. Questions additionally emerged and were refined through interaction with the analytics. Data interpretation involved two distinct activities, often along with affective reactions to data: reading data toidentify noteworthy patterns and explaining their importance in the course using contextual knowledge. Pedagogical responses to the analytics included whole-class scaffolding, targeted scaffolding, and revising course design, as well two new non-action responses: adopting a wait-and-see posture and engaging in deep reflection on pedagogy. Findings were synthesized into a model of instructor analytics use that offers useful categories of activities for future study and support

Desenvolvimentismo, plano-piloto e segregação
Authors: Silva Meire Oliveira
Published: August 2019

Brasília, contradições de uma cidade nova (1967) é um filme de Joaquim Pedro de Andrade cujo projeto foi encomendado e financiado pela Olivetti. No entanto, por não atender às exigências da empresa, e por correr o risco de se embater com o governo vigente, não chegou a ser exibido na época. A recusa deveu-se à exposição das fissuras da desigualdade presentes na capital federal, cujo plano inicial ancorava-se no intuito de dissipar qualquer desnível social, capaz de alçar o Brasil aos patamares progressistas da década de 1960. Todavia, mostra uma cidade nova e planejada capaz de concentrar e desnudar todas as contradições sociais existentes no país, sobretudo com a migração nordestina que foi relegada às cidades-satélites. Todos essesparoxismos associam-se ao desmantelamento educacional, por meio da paralisação da Universidade de Brasília, espécie de microcosmo do sistema educacional brasileiro, no documentário. E tal contiguidade reflete o próprio caos social do país em todas as suas esferas.
A emergência das heterogeneidades enunciativas no discurso indigenista oficial brasileiro

Published: August 2019

Este trabalho objetiva problematizar emergências de heterogeneidade(s) enunciativa(s) (AUTHIER-RÉVUZ, 1990, 1998, 2004) no Documento Base, elaborado para embasar a 1ª Conferência Nacional de Política Indigenista. Alicerça-se nos estudos da AD de origem francesa e no método arquegenealógico (FOUCAULT, 2015), em sua perspectiva dicursivo-desconstrutiva (CORACINI, 2007, GUERRA, 2011). Os resultados obtidos indicam que a utilização das aspas na materialidade discursiva analisada se deu, primeiro, como recurso preventivo contra a apropriação da ideia alheia, depois pela necessidade de o sujeito enunciador eximir-se da responsabilidade sobre o sentido de determinados itens lexicais e, por fim, como questionamentodo efeito de sentido evocado pelas palavras aspeadas.
Wittgenstein and Derrida on the Possibility of Meaning: Hierarchy or Non-Hierarchy, Simple or Non-simple Origin, Deferral or Non-Deferral
Authors: MacDonald Neil B
Published: August 2019

Meaning understood in terms of teachability and learnability is crucial to Wittgenstein’s later work. As regards the resolution of philosophical problems – and epistemological problems in particular - this approach seems to posit a hierarchy of meaning that excludes endless deferral. This is the basis of Wittgenstein’s attack on philosophical scepticism. Derrida’s approach to language seems to require both non-hierarchy and endless deferral. Consequently fundamental to his concept of origin is identity and difference simultaneously, irreducibly, non-simply. One question is whether it is possible for there to be a compromise between the two philosophers: a hierarchy of meaning that does not in principle exclude endless deferral.

Published: August 2019

Objectives. The reconstruction after nasal skin cancer (NSC) resection is often practiced differently. The objective of this study is to evaluate the influence of patient-, tumor- and management-related factors on the role of surgery and choice of reconstruction.Methods. This was a monocentric retrospective study of patients who were diagnosed with a NSC (squamous cell or basal cell carcinoma) and suffered from an extended defect after ablative surgery between 2003 and 2013. Twenty-five patients were included. Tumors were staged using the Union for International Cancer Control (eighth edition) TNM classification for primary cutaneous skin cancer of the head and neck. Preferred treatment was surgery in all patients. Health-related quality of life (HRQoL) measurement was evaluated by one generic (36-Item Short Form Health Survey [SF-36]) and two organ-specific questionnaires (Rhinoplasty Outcome Evaluation [ROE] and Functional Rhinoplasty Outcome Inventory 17 [FROI-17]) after therapy. Survival data were estimated by the Kaplan-Meier method and statistical analysis was performed by log-rank, analysis of variance, Levene’s and t-tests. The median follow-up time was 2.1 years.Results. According to the Union for International Cancer Control classification, 13 of 25 tumors were staged as pT1 (52%), four as pT2 (16%), seven as pT3 (28%) and one as pT4a (4%). Seventy-two percent of patients (n=18) chose plastic reconstruction, and for the remaining 28% (n=7) of the patients opted for an implant-retained prosthesis. The overall survival was 69.5% after 5 years, the 5-year recurrence-free survival was 90.9% and the 5-year disease-specific survival was 100%. There was no significant difference in the HRQoL outcome between both rehabilitation methods.Conclusion. Surgery in NSC gives an excellent oncologic prognosis. Nasal reconstruction and prostheses are both very viable options depending on tumor stage and biology, the patient’s wishes as well as the experience of the surgeon.

Published: August 2019

Background: Polycystic ovarian syndrome (PCOs) is one of the most common endocrine disorders in women throughout the world affecting their sexual/ reproductive health (SRH). Objective: This scoping review aims to identify SRH needs of women with PCOs
Methods: PubMed, SCOPUS, Google Scholar, MEDLINE, Science Direct, Ovid and the Cochrane Library were screened from 2000 to 2019. English or Persian peer reviewed and gray literature sources were included. In the primary search, 52 articles were obtained; and finally by narrative synthesis framework for quality assessment, and data analysis and synthesis 27 articles were analyzed.
Results: From the 27 selected articles, 9 main themes were obtained i.e.: Complications and problems affecting patients, Lifelong effect of PCOs on reproductive patterns , PCOs and adverse reproductive and pregnancy outcomes, Information needs and preferences of patients about health outcomes and their application for treatment and management of lifelong health outcomes, Financial burden of disease, The effect of PCOs on life experiences and quality of life of affected women, Sexual disorders, Psychological concerns and issues, Femininity feelings and roles
Conclusion: Comparison of the 9 themes developed in this study with SRH needs in women, revealed that some of the issues, such as psychological challenges, patients' femininity feelings and roles and financial burden of disease have been ignored in providing SRH services, and should be taken into consideration.

Authors: Asrat Dereje Zena , Achamyeleh Anemaw Asrat , Ayalew Agumas Fentahun
Published: August 2019

Background: One of the major problems in developing countries is the increasing growth of population which in fact is a serious threat for the global community. Modern Contraceptive use allows people to attain their desired number of children and determine the spacing of pregnancies. The main objective of this study is to assess the Prevalence of modern contraceptive utilization and associated factors among women of reproductive age from 36-49 years in Ethiopia.
Methodology: A community based, cross-sectional study was employed from January 1 to June 30, 2016, among women of reproductive age from 36-49 years in all regions of Ethiopia. A multi-stage sampling procedure was used to select 3260 study participants. A pretested structured questionnaire was used to collect data, and data collectors who had completed high school were involved in the data collection process. A bivariate, multivariable logistic regression model was fit and statistical significance was determined with odds ratios and 95 % confidence level. Before preceding data analysis, the necessary assumptions for the application of multiple logistic regressions was checked by Hosmer and Lemeshow Test through forward LR method.
Result: The overall modern contraceptive prevalence rate was found to be 17%. Being wealthy (Adjusted Odds Ratio=4.120 95%CI (2.853, 5.949), higher educated (Adjusted Odds Ratio =3.329, 95%CI (2.065, 5.368) and having more numbers of living children (Adjusted Odds Ratio =1.714, 95% (1.328, 2.212) was significantly associated with use of modern contraceptive methods.
Conclusion: The utilization of modern contraceptive method was low. Contraceptive utilization was associated with some socio-economic and socio-demographic factors like age, educational status, women wealth index and number of children. Therefore, expanding contraceptive services confers substantial benefits on women, their families and society. All stakeholders, including the Ethiopian government and the private sector, should increase their investment in modern contraceptive services

The grapevine homeobox gene VvHB58 influences ovule and fruit development through multiple hormonal signaling pathways
Authors: Li Yunduan , Zhang Songlin , Dong Ruzhuang , Wang Li , Yao Jin , Nocker Steve van , Wang Xiping
Published: August 2019

Abstract
Background: Seedlessness is one of the most valuable traits in grapevine (Vitis vinifera), especially for the raisin and table grape industries. Previous transcriptome analyses of seed development in grape hybrids suggested that specific homeodomain transcription factors are involved in seed abortion in seedless cultivars. However, the molecular mechanism of homeobox gene regulating seed abortion is rarely reported.
Results: Here, we report that the grapevine VvHB58 gene, encoding a homeodomain-leucine zipper (HD-Zip I) transcription factor, participates in regulating fruit size and seed number. The VvHB58 gene was dramatically differentially expressed during seed development between seedless and seeded cultivars. Subcellular localization assays revealed that the VvHB58 protein was located in the nucleus. Transgenic expression of VvHB58 in tomato led to loss of apical dominance, a reduction in fruit pericarp expansion, reduced fruit size and seed number, and larger endosperm cells. Analysis of the sequence and cytosine methylation within the VvHB58 promoter indicated that the differential expression during seed development between seedless and seeded grapes may be caused by different transcriptional regulatory mechanisms rather than promoter DNA methylation. Measurements of five classic endogenous hormones and expression analysis of hormone-related genes between VvHB58 transgenic and nontransgenic control plants showed that expression of VvHB58 resulted in significant changes in auxin, gibberellin and ethylene signaling pathways. Additionally, several DNA methylation-related genes were expressed differentially during seed abortion in seedless and seeded grapes, suggesting hypomethylation during ovule development may be associated with seed abortion.
Conclusion: VvHB58 has a potential function in regulating fruit and seed development by impacting multiple hormonal pathways. These results expand understanding of homeodomain transcription factors and potential regulatory mechanism of seed development in grapevine, and provided insights into molecular breeding for seedless grapes.

Published: August 2019

Background

Patients with oligometastatic disease can potentially be cured by using an ablative therapy for all active lesions. Stereotactic body radiotherapy (SBRT) is a non-invasive treatment option that lately proved to be as effective and safe as surgery in treating lung metastases (LM). However, it is not clear which patients benefit most and what are the most suitable fractionation regimes. The aim of this study was to analyze treatment outcomes after single fraction radiosurgery (SFRS) and fractionated SBRT in patients with lung oligometastases and identify prognostic clinical features for better survival outcomes.

Methods

Fifty-two patients with 94 LM treated with SFRS or fSBRT (Cyberknife, Novalis) between 2010 and 2016 were analyzed. The characteristics of primary tumor, LM, treatment, toxicity profiles and outcomes were assessed. Kaplan-Meier and Cox regression analyses were used for estimation of local control (LC), overall survival (OS), progression free survival and distant metastases free survival (DMFS).

Results

Ninety-four LM in 52 patients were treated using SFRS/fSBRT with a median of 2 lesions per patient (range: 1–5). The median prescription dose for SFRS was 24 Gy (range: 17-26) compared to 48 Gy (range: 24-75) in 2-12 fractions in fSBRT. The median follow-up time was 21 months (range: 3-68). LC rates at 1 and 2 years for SFSR vs. fSBRT were 89% and 83% vs. 75% and 59%, respectively (p=0.026). LM treated with SFSR were significantly smaller (p=0.001). The 1 and 2-year OS rates for all patients were 84% and 71%, respectively. In univariate analysis treatment with SFRS, an interval of ≥ 12 months between diagnosis of LM and treatment, non-colorectal cancer histology and BED <100 Gy were significantly associated with better LC. However, none of these parameters remained significant in the multivariate Cox regression model. OS was significantly better in patients with negative lymph nodes (N0), Karnofsky performance status (KPS) > 70% and DMFS ≥ 12 months. There was no grade 3 acute or late toxicity.

Conclusions

We observed good LC and low toxicity rates after SFRS for small lung metastases. Long DMFS, good KPS and N0 predicted longer OS in patients with lung oligometastases.

Published: August 2019

Background

There is no conclusive evidence regarding a causal relationship between periodontitis and atherosclerosis. In this study, we examined the microbiome in the oral cavity and atheromatous plaques from atherosclerosis patients with or without periodontitis to investigate the role of oral bacteria in the formation of atheromatous plaques. We chose four patients with and without periodontitis, who had undergone carotid endarterectomy. Bacterial samples were extracted from saliva on the tongue surface, from periodontal pocket (during the oral examination), and from the atheromatous plaques. We investigated the general and oral conditions from each patient and performed next-generation sequencing analysis for all bacterial samples.

Results

There were no significant differences between both groups concerning general conditions. However, the microbiome patterns of the gingival pocket showed differences depending on the absence or presence of periodontitis, while those of the saliva were relatively similar. The microbiome pattern of the atheromatous plaques was entirely different from that in saliva present on the tongue surface and gingival pocket, and oral bacteria were seldom detected. However, the microbiome pattern in atheromatous plaques was different in the presence or absence of periodontitis.

Conclusion

These results indicated that oral bacteria did not affect the formation of atheromatous plaques directly. However, the metabolic products of microbiome or the host inflammatory response might indirectly influence the composition of atheromatous plaques.
House-hold contact tuberculosis screening adherence and associated factors among tuberculosis patients attending at Health facilities in Gondar town, Northwest, Ethiopia
Authors: Shiferaw Dessie Alemnew , Mekonnen Habtamu Sewunet , Abate Addisu Taye
Published: August 2019

Abstract
Background: Contacts of patients with tuberculosis have a substantial risk of developing the disease. Household contact screening has recently been recommended as a strategy to enhance case detection in high-burden countries but there is no enough information in Gondar Town regarding household contact screening practice among TB patients.
Objective: The aim of this study was to assess the magnitude of household contact screening adherence and associated factors among adult tuberculosis patients attending at health facilities in Gondar Town, Northwest Ethiopia.
Methods: An institution-based cross-sectional study was conducted from March 1 to 30, 2019 on 404 tuberculosis patients attending at health facilities in Gondar Town. Epi-Info version 7 for data entry and SPSS version 20 for data analysis were used. Descriptive statistics were carried out to illustrate the means, standard deviations, and frequencies of study variables. Bivariable and multivariable logistic regression analyses were used to identify variables having a significant association with the dependent variable.
Results: From 412 study populations, 404 participated with 98.06% response rate. The overall household contact TB screening adherence was 47.5% (95% CI: 43.1, 52.5). In the multivariable analysis, certificate and above educational level (AOR=2.83, 95% CI:1.40,5.67), sufficient knowledge on TB (AOR=8.26, 95% CI:4.34,15.71), satisfied patients with delivered health care service (AOR=3.26, 95% CI:1.58,6.76), health education given by health care worker (AOR=2.60, 95% CI:1.54,4.40),and HIV/AIDS co-infection (AOR=3.54, 95% CI:1.70,7.39), were factors associated with household contact TB screening adherence.
Conclusion: Compared to other previous studies, the current finding was high but it was low as compared with WHO and Ethiopian Ministry of Health recommendations (all persons having TB contact should be screened). Educational status, knowledge on TB, satisfaction with delivered health care service, health education given by HCWs about TB and HIV/AIDS co-infection were factors associated with household contact TB screening practice. Thus, strengthening household TB contact screening and educational programs regarding the risk of getting TB infection from household contacts is crucial.

Expression of cytoglobin and PGC-1α is high during tail tissue regeneration of the house gecko (Hemidactylus platyurus)
Authors: Novianti Titta , Juniantito Vetnizah , Jusuf Ahmad Aulia , Arida Evy Ayu , Sadikin Mohamad , Jusman Sri Widia A.
Published: August 2019

Abstract
Background
Tissue regeneration is a process that need a high demand of oxygen and energy supply. Cytoglobin (Cygb) is a hexacoordinate globin superfamily that possesses strong oxygen-binding ability. Cygb also has a role in preventing cells from oxidative stress and carrying oxygen into the mitochondria. The production of energy for regeneration is associated with mitochondria, especially mitochondrial biogenesis. The peroxisome proliferator-activated receptor gamma coactivator (PGC-1α) is aprotein that plays an important role in regulating mitochondrial biogenesis. The house gecko (Hemidactylus platyurus) is a reptile with high ability for tissue regeneration in its tail. The house gecko was selected as the animal model for this research to analyse the role of Cygb which is associated with oxygen supply and PGC-1α that is related to energy production in tissue regeneration.
Results
The curve for the tail growth showed three different phases. Cygb mRNA was highly expressed during tissue regeneration. PGC-1α mRNA was expressed earlier than Cygb, with a lower expression but still higher than the control.
Conclusions
During the tail tissue regeneration process of the house gecko, the expression of Cygb and PGC-1α were dynamic and relatively higher than their expression observed in the control. Cygb and PGC-1α were suspected to have a significant role in the tissue regeneration process.
Financial shielding that Bitcoin grants to capitals in the world

Published: August 2019

Market forces are not the only influence on currency exchange rates. They can change due to monetary and fiscal policies among other international repercussions. Bitcoin, for its independence from all the central banks worldwide, has a natural shield that will change the direction in the economic policy of the industrialized countries. The research aim is to analyze the influence that indicators and financial assets can have on Bitcoin. The study tries to confirm the reasons why it has begun to be the solution in economies with unstable currencies.The behavior of the different agents appears as the core of the study. It is creating a backward 5-year work horizon. The data are continuous values, and they are the numerical variables for Pearson correlation analysis. The time series in fixed periods are the basis for the study of projections. Besides, the Relative Strength Index or Relative Strength Index called Welles Wilder is useful in the research. Bitcoin does not get influenced by the Dow Jones, gold price, and Gross Domestic Product (GDP). The independence in the creation of this cryptocurrency could in the long term end up turning it into a currency of world use. As a result, the understanding and management of this cryptocurrency could generate new ways of building the future monetary system. The new direction of the economy will be registered in the blockchain and not in a central bank.
Achieving water security in peri-urban Yangon: exploring the local governance processes
Authors: Groot Rebecca , Bayrak Mucahid Mustafa
Published: August 2019

Many cities in the Global South lack the capacity to provide water security to their inhabitants. Peri-urban areas are especially vulnerable to water insecurity. This study concerns the impact of (good) governance on water security among formal and informal settlers residing in Hlaing Thar Yar Industrial Zone (HTIZ), a peri-urban area belonging to Yangon, Myanmar. Through employing mixed methods, we investigate the dynamics of water security by studying the governing processes which shape it on a local level. In HTIZ, various challenges related to water security come together. Our findings reveal that water security in HTIZ was achieved for the majority of the formal settlers, whereas this was not the case for the majority of the informal (riverbank) settlers. Although a well-organized needs-driven system of local water vendors supplied water to the local population there was a high risk of contamination by domestic pollution (e.g., Escherichia coli) and industrial effluent, in addition to the relatively high price of the water. The identified water insecurities were driven on an institutional level by the lack of capacity and priority given to supplying and protecting informal settlers. Absence of environmental monitoring and enforcement, and the perceptions of government officials further exacerbated water insecurity.
Determinants of water lobbying: irrigators' behavior in a water-stressed basin
Authors: Esteban Encarna , Dinar Ariel , Albiac José
Published: August 2019

The design and implementation of water policies to address scarcity problems are largely shaped by the behavior of interest groups and their ability to influence policymakers. Different and opposed interests of stakeholders regarding policies trigger water conflicts and, frequently, lead to the failure of the implemented regulation. Departing from political economy theory, we empirically estimate the determinants that affect the level of lobbying effort and effectiveness by water interest groups for influencing water policy. The findings are based on data collected by a survey administered among different irrigators' groups, in a water-stressed river basin (the Jucar River Basin in Spain) that vie to increase their water allocations. Our results demonstrate how lobbying effort depends on the involvement of the interest groups, the energies exerted to sway water authorities, and on the variation among the group members. Lobbying effectiveness is a function of the effort exerted. Furthermore, both functions depend on the intrinsic characteristics of the group's members. While the empirical results corroborate several main statements of the theory of lobbying and interest groups, some deviations based on the empirical application remain.
Advancing the Science of Recruitment for Family Caregivers: Focus Group and Delphi Methods
Authors: Hansen Dana , Petrinec Amy , Hebeshy Mona , Sheehan Denice , Drew Barbara L
Published: August 2019

Background

Successful recruitment of participants is imperative to a rigorous study, and recruitment challenges are not new to researchers. Many researchers have used social media successfully to recruit study participants. However, challenges remain for effective online social media recruitment for some populations.

Objective

Using a multistep approach that included a focus group and Delphi method, researchers performed this study to gain expert advice regarding material development for social media recruitment and to test the recruitment material with the target population.

Methods

In the first phase, we conducted a focus group with 5 social media experts to identify critical elements for effective social media recruitment material. Utilizing the Delphi method with 5 family caregivers, we conducted the second phase to reach consensus regarding effective recruitment videos.

Results

Phase I utilized a focus group that resulted in identification of three barriers related to social media recruitment, including lack of staff and resources, issues with restrictive algorithms, and not standing out in the crowd. Phase II used the Delphi method. At the completion of Delphi Round 1, 5 Delphi participants received a summary of the analysis for feedback and agreement with our summary. Using data and recommendations from Round 1, researchers created two new recruitment videos with additions to improve trustworthiness and transparency, such as the university’s logo. In Round 2 of the Delphi method, consensus regarding the quality and trustworthiness of the recruitment videos reached 100%.

Conclusions

One of the primary challenges for family caregiver research is recruitment. Despite the broad adoption of social media marketing approaches, the effectiveness of online recruitment strategies needs further investigation.

Seaweeds are potential foodstuff and source of bioactive substances that are very useful in the food and pharmaceutical industries. The objective of this study was to evaluate toxicity of aqueous extracts of seaweeds by Brine shrimp lethality test (BLT) and cytotoxicity test.  The seaweeds used in this study were Enteromorpha sp. and Laurencia sp. collected from the Gunungkidul coastal line. The cytotoxicity test was performed against a normal cells line of Vero cells and a cancer cells line of HeLa cells. The cells lines were cultured in M119 medium with addition of 10% FBS and incubated at 37°C in CO2 incubator until confluent. Cells were harvested and cultured in 96 microplate with an initial density of 2x104 cells / 100 ml / well.  The cells lines were treated with seaweed extracts at 24 hours after incubation. After additional 24 h incubation, the cell proliferation was observed by MTT method (3- [4,5-dimethylthiazol-2-yl] -2,5- diphenyltetrazolium bromide.The results showed that the two aqueous extract were not toxic in the BLT test, and did not exhibited any cytotoxicity activity against HeLa and Vero cells lines. Concentration-dependent cell proliferation was also not found. This results indicated that Enteromorpha sp.  and Laurencia sp. extracts were no cytotoxic and might be consumed safely. These overall results suggested that the two seaweeds might be developed to be a new foodstuff  for humans.

Mentoring families and people with cleft lip and palate surgery to treatment are still not optimal in Jember city. Due before 2014, there is no hospital that specializes in the treatment of cleft lip and palate social concept, partnering with community empowerment companion. It is also caused by a lack of specific strategies used by the facilitators for this. The existence of a social marketing volunteer strategy, a strategy that has been shown to have positive implications for the handling of cleft lip and palate due to effective direct communication between social worker with sufferers and their families so that patients and families more easily understanding the process of handling lip and palate. This improved can reduce the morbidity and even mortality rates in Jember agroindustry area. In this community service, we engage in activities that consist of 1) the stage of pre-hospitalization, 2) phase of hospitalization and, 3) the stage of post-hospitalization. The purpose of this public service is to apply the strategy social marketing volunteers in order to streamline the handling of cleft lip and palate. Mentoring families and people with cleft lip and palate surgery to treatment using strategy volunteer social marketing are very efficient.
Determinación Mejorada del Volumen de Pesas Patrón por Medición Geométrica

Published: August 2019

Purpose  ̶  to develop an improved mathematical model for volume determination of standardized weights by geometric measurement.

Methodology  ̶  the new model eliminates an assumption considered in the current model published in the OIML R 111-1 recommendation, since it considers existing deviations from the assumed shape of the weights in the current model, specifically in the so-called knob and ring sections. These deviations might originate during the manufacturing processes of the weights.

Results  ̶  an improved mathematical model for the calculation of the volume of standard weights by geometric measurement was deduced. Additionally, the model has the advantage of eliminating the risk of scratching the weights, which makes it possible to extend the use of the new model to higher accuracy classes.

Limitations  ̶  the proposed model involves the possibility of making geometric measurements without surface contact of the weights, for example, with an optical comparator.

Findings  ̶  an assessment of the current model against data previously published allows highlighting the relevance and higher accuracy of the new model, which makes it possible to calculate the density of standard weights, even for E class, through only geometric measurements.

A finales del siglo XVI, varios españoles realizaron solicitudes de mercedes al virrey por alguna porción de tierra. Juan del Castillo hizo una solicitud por 4 caballerías de tierras, 3 de ellas a las faldas del cerro Tultepec. El objetivo del presente artículo es analizar un pleito entre los indios de Tultepec y Juan del Castillo resultado de dicha solicitud, de la cual hay un mapa. Asimismo, se relacionará dicho mapa con el paisaje actual, para conocer los cambios y permanencias de un paisaje rico en recursos naturales.

Learners should learn English language basic skills and also the components such as grammar, pronunciation, and vocabulary. The learners will have a difficulty in understanding interlocutor’s mean or expressing their ideas without having a sufficient vocabulary. In learning vocabulary, students may have various strategies used to improve their vocabulary. High-achiever students are considered as students who perform well in school and have a high academic achievement. This research is conducted to find out the most common strategy in learning vocabulary used by high achiever students and the reasons in choosing the strategy. Mixed methods, which combine quantitative and qualitative research design was applied for this research. Then, the instruments of this research are questionnaire and interview. The researcher takes seventh-semester high-achiever students as population and 26 high-achiever students who have Grade Point Average (GPA) 3, 51 - above were taken as the sample of this research. The result showed that the most common strategy employed by high-achiever student is cognitive strategy with mean score of 79.8. The strategies involved were note-taking, highlighting, analyzing, dictionary-use, etc. The high-achiever students preferred to use cognitive strategy because it helped them in learning English skill, easy to apply, to make them speak English well, effective and also it is comfortable to use during learning process Therefore, appropriate learning strategies would help the students perform their English well.
Doğu Akdeniz Bölgesi Dört ve Beş Yıldızlı Şehir Otellerinde İşgören Devir Hızı Üzerine Bir Araştırma

Turizm Sektöründe
işgören devrinin yüksek olduğuna ilişkin genel bir kabul olmasına karşın
Türkiye’de konuyla ilgili yapılan araştırmalar genellikle yalnızca bir
destinasyonu ya da bir ili kapsamaktadır. Bu konuda kapsamlı bilimsel veriler
elde edebilmek için daha geniş alanları kapsayan çalışmalar yapılması
gerekmektedir. Bu ihtiyaçtan hareketle turizm sektörünün bir parçası olan
konaklama işletmelerinde yaşanan işgören devir oranı ve bu işgören devrinin
nedenleri bölgesel düzeyde araştırılmıştır. Araştırma, Doğu Akdeniz
Bölgesi’ndeki 4 ve 5 yıldızlı şehir otellerinde gerçekleştirilmiştir. Çalışma
nicel bir araştırma olup veriler anket aracılığı ile toplanmıştır. Elde edilen
veriler, analiz edilerek yorumlanmıştır. Araştırma sonuçlarında Doğu Akdeniz
Bölgesi işgören devir hızının yüksek olduğu, kendi isteği ile ayrılanların
ayrılma sebeplerinin ücreti yetersiz bulma ve zorunlu nedenler olduğu; yönetim
tarafından çıkarılma nedenlerinin ise, işgörenin işinin gerektirdiği
performansı gösterememesi ve işletme kurallarına uyulmaması olduğu
belirlenmiştir. İşletmelerin işgören devrinden gördükleri zararı en aza
indirmek amacıyla, işletmenin idari bölümlerine daha deneyimli işgörenleri
istihdam etmeleri gerekmektedir.
Beyond White Architecture: Therapeutic gardens for patients with tuberculosis in the sanatoria of the Greater Lisbon area (1870-1970)
Authors: Avelãs Nunes José
Published: August 2019

This article discusses the concept of therapeutic garden— its definition and importance, — in the context of the specific architecture of sanatoria for the treatment of tuberculosis, in particular the case of Lisbon’s sanatoria from 1870 to 1970.

It contemplates both national and international networks of circulation and transfer of knowledge before and after the medical and architectural revolutions at the turn of the twentieth century. These revolutions were accompanied by significant changes in the city’s structure concerning the control of epidemics and social diseases. Architects and physicians, among other experts, are the main characters to be scrutinized, alongside with their architectural and scientific production and their entanglements. At the same time, I seriously take into consideration their interactions with the spheres of power, specifically in what relates to management and decision making.
A Bit More Than a Bit Is More Than a Bit Better
Authors: Hafiz Syed Mahbub , Henry Ryan
Published: August 2019

We study both the practical and theoretical efficiency of private information retrieval (PIR) protocols in a model wherein several untrusted servers work to obliviously service remote clients’ requests for data and yet no pair of servers colludes in a bid to violate said obliviousness. In exchange for such a strong security assumption, we obtain new PIR protocols exhibiting remarkable efficiency with respect to every cost metric—download, upload, computation, and round complexity—typically considered in the PIR literature.

The new constructions extend a multiserver PIR protocol of Shah, Rashmi, and Ramchandran (ISIT 2014), which exhibits a remarkable property of its own: to fetch a b-bit record from a collection of r such records, the client need only download b + 1 bits total. We find that allowing “a bit more” download (and optionally introducing computational assumptions) yields a family of protocols offering very attractive trade-offs. In addition to Shah et al.’s protocol, this family includes as special cases (2-server instances of) the seminal protocol of Chor, Goldreich, Kushilevitz, and Sudan (FOCS 1995) and the recent DPF-based protocol of Boyle, Gilboa, and Ishai (CCS 2016). An implicit “folklore” axiom that dogmatically permeates the research literature on multiserver PIR posits that the latter protocols are the “most efficient” protocols possible in the perfectly and computationally private settings, respectively. Yet our findings soundly refute this supposed axiom: These special cases are (by far) the least performant representatives of our family, with essentially all other parameter settings yielding instances that are significantly faster.
Monte Carlo and Reconstruction Membership Inference Attacks against Generative Models
Authors: Hilprecht Benjamin , Härterich Martin , Bernau Daniel
Published: August 2019

We present two information leakage attacks that outperform previous work on membership inference against generative models. The first attack allows membership inference without assumptions on the type of the generative model. Contrary to previous evaluation metrics for generative models, like Kernel Density Estimation, it only considers samples of the model which are close to training data records. The second attack specifically targets Variational Autoencoders, achieving high membership inference accuracy. Furthermore, previous work mostly considers membership inference adversaries who perform single record membership inference. We argue for considering regulatory actors who perform set membership inference to identify the use of specific datasets for training. The attacks are evaluated on two generative model architectures, Generative Adversarial Networks (GANs) and Variational Autoen-coders (VAEs), trained on standard image datasets. Our results show that the two attacks yield success rates superior to previous work on most data sets while at the same time having only very mild assumptions. We envision the two attacks in combination with the membership inference attack type formalization as especially useful. For example, to enforce data privacy standards and automatically assessing model quality in machine learning as a service setups. In practice, our work motivates the use of GANs since they prove less vulnerable against information leakage attacks while producing detailed samples.
