Layanan Informasi Pembayaran Biaya Kuliah Berbasis SMS Interaktif Pada Sekolah Tinggi XYZ
Authors: Sihotang Fransiska Prihatini , Jumeilah Fithri Selva
Published: July 2019

Sekolah Tinggi XYZ adalah salah satu perguruan tinggi yang sudah menggunakan elearning. Sistem ini digunakan oleh dosen, mahasiswa, dan administrator. Dosen dan mahasiswa menggunakan sistem ini untuk menunjang proses belajar mengajar. Sedangkan administrator menggunakannya untuk mengirimkan informasi yang berkaitan dengan akademis seperti jadwal perkuliahan, jadwal ujian, pengumuman pembayaran, dan lainnya. Setiap semester, administrator akan mengumumkan informasi pembayaran Biaya Pengembangan Pendidikan (BPP) dan biaya Satuan Kredit Semester (SKS) sesuai dengan jadwal yang telah ditentukan. Namun, pengumuman itu hanya sampai kepada para mahasiswa dan belum sampai pada orang tua. Sampai sekarang orang tua mahasiswa masih belum terbiasa dengan penggunaan internet sehingga mereka tidak bisa mengakses situs e-learning anaknya. Karena itu, masih banyak mahasiswa yang terlambat melakukan pembayaran. Pembayaran terlambat dapat menyebabkan siswa membayar denda atau menunda kuliah. Untuk mencegah hal ini, sebuah sistem informasi dibuat untuk menyebarkan informasi jadwal pembayaran melalui SMS gateway. Sistem akan dibangun menggunakan Gammu sebagai server SMS gateway dan menggunakan framework Ruby on rails. Dengan sistem ini informasi jadwal pembayaran akan tiba langsung ke orang tua siswa. Jika orang tua ingin bertanya tentang jadwal pembayarannya, orang tua cukup mengirim SMS sesuai dengan format yang telah ditentukan.

Wine and the "Spirit" of the Territory: The Langhe Case as a Successful Wine Tourism Destination "System"
Authors: Giacosa Elisa , Rossi Matteo , Festa Giuseppe , Ferraris Alberto
Published: July 2019

The emerging importance of wine tourism clearly affects not only wineries but also, and above all, wine territories. When this happens, the territory can become not only a wine tourism destination but also a wine tourism destination "system." Thus, the article's focus is to deeply analyze
the successful and internationally famous Italian case of Piedmont (Italy) as a wine tourism destination and more specifically the area of Langhe as a wine tourism destination "system." There are two main findings of this research. First, we have verified why the Langhe is more than an emerging
wine tourism destination through a theoretical/empirical framework and the natural systemic functioning for the normal essence of this territory. In addition, we have also verified how the "business model" of this wine tourism destination system is sustainable, considering that this area has
been able to reengineer its way of surviving and growing, putting wine at the center of this restructuring. This research has several theoretical and practical implications. First, it emphasizes the role of different common goods in the creation of a successful wine tourism destination system.
Practical implications may involve various types of stakeholders, and the main implications concern both private and public operators.

Authors: Candelo Elena , Casalegno Cecilia , Civera Chiara , Büchi Giacomo
Published: July 2019

This study is focused on the issue of agritourism in developing countries, which is a growing phenomenon and an understudied topic by the academic literature. By developing an investigation on coffee tourism based on multiple stakeholder perspectives around the subject, we contribute to further the debate over potentialities and benefits of coffee tourism development. We applied grounded theory methodology and through an iterated process involving literature review, a case study on Costa Rica, interviews with coffee experts, and a survey with European tourists, we designed a theoretical framework of the benefits that coffee tourism can have on both local farmers, who are vulnerable and lowpower stakeholders within the coffee supply chain, and on actual and potential coffee tourists. Our research pointed out that empowerment and cooperation, business diversification, sustainability, and creation of a destination image are the four main benefits for the local communities of farmers and their families and are also perceived to be creating favorable and attracting conditions for tourists.

Published: July 2019

Introduction: Total pancreatectomy for pancreatic ductal adenocarcinoma has historically been associated with substantial patient morbidity and mortality. Given advancements in perioperative and postoperative care, evaluation of the surgical treatment options for pancreatic adenocarcinoma should consider patient outcomes and long-term survival for total pancreatectomy compared with partial pancreatectomy. Methods: The U.S. National Cancer Database was queried for patients undergoing total pancreatectomy or partial pancreatectomy for pancreatic adenocarcinoma during 1998–2006. Demographics, tumour characteristics, operative outcomes, 30-day mortality, 30-day readmission, additional treatment, and Kaplan–Meier survival curves were compared. Results: The database query returned 807 patients who underwent total pancreatectomy and 5840 who underwent partial pancreatectomy. More patients who underwent total pancreatectomy than a partial pancreatectomy had a margin-negative resection (p < 0.0001). Mortality and readmission rates were similar in the two groups, as was long-term survival on Kaplan–Meier curves (p = 0.377). A statistically significant difference in the rate of surgery only (without additional treatment) was observed for patients in the total pancreatectomy group (p = 0.0003). Conclusions: Although total compared with partial pancreatectomy was associated with a higher rate of margin-negative resection, median survival was not significantly different for patients undergoing either procedure. Patients who underwent total pancreatectomy were significantly less likely to receive adjuvant therapy.

Published: July 2019

Introduction: The pan-Canadian Oncology Symptom Triage and Remote Support (costars) team is studying how to improve the quality and consistency of cancer symptom management. Methods: A 1-day invitational meeting was held 24 October 2017 in Ottawa, Ontario, to review the current evidence from costars projects and to establish research priorities for a future largescale implementation study. The meeting included 36 participants who were clinicians from adult oncology, pediatric oncology, and homecare; policymakers from national, provincial, and regional organizations; researchers; and a patient. Half the day involved summarizing evidence from four costars studies and experiences with implementing the costars symptom practice guides. The second half of the day used a modified nominal group technique to generate research questions within small groups, presentation of research questions to all participants, and two rounds of voting to reach consensus on research priorities. Results: Participants proposed 4 research categories: (1) User-centred augmentation to enhance usability (for example, designing a mobile costars solution); (2) Outcome measurement (for example, determining key competencies for clinicians); (3) Regular renewal of costars to keep pace with evolving evidence (for example, updates for novel therapies); (4) Integration into clinical practice (for example, meaningful engagement of patients and caregivers in study design). Conclusions: Across categories, the top 3 priorities were effect on health services use, competency development, and a mobile costars solution. Future research will address identified priorities, reflecting the needs and perspectives of diverse stakeholders. Stakeholder collaboration will continue to guide our approach to operationalizing this priority research agenda.
Association of Preoperative Anemia and Perioperative Allogenic Red Blood Cell Transfusion with Oncologic Outcomes in Patients with Nonmetastatic Colorectal Cancer
Authors: Kwon H. Y. , Kim B. R. , Kim Y. W.
Published: July 2019

Background: We investigated whether preoperative anemia and perioperative blood transfusion (PBT) are associated with overall survival and recurrence-free survival in patients with nonmetastatic colorectal cancer. Methods: From 1 January 2009 to 31 December 2014, 1003 patients with primary colorectal cancer were enrolled in the study. Perioperative clinical and oncologic outcomes were analyzed based on the presence of preoperative anemia and PBT. Results: Preoperative anemia was found in 468 patients (46.7%). In the anemia and no-anemia groups, PBT was performed in 44% and 15% of patients respectively. Independent predictors for PBT were preoperative anemia, higher American Society of Anesthesiologists score, laparotomy, lengthy operative time, advanced TNM stage, T4 stage, and 30-day morbidity. The use of PBT, but not preoperative anemia, was found to be an independent adverse prognostic factor for overall survival. In terms of recurrence-free survival, the presence of preoperative anemia was similarly not a significant prognostic factor, but the use of PBT was an independent factor for an unfavourable prognosis. Conclusions: The use of PBT, but not preoperative anemia, was independently associated with worse overall and recurrence-free survival in nonmetastatic colorectal cancer. For better oncologic outcomes, our findings indicate a need to reduce the use of blood transfusion during the perioperative period.
Direct Comparison of the Thickness of the Parietal Peritoneum Using Peritoneal Biopsy and Ultrasonography of the Abdominal Wall in Patients Treated with Peritoneal Dialysis

Published: July 2019

Background

Long-term treatment with peritoneal dialysis (PD) results in peritoneal fibrosis. Peritoneal biopsies have been used to determine the severity of fibrosis. Ultrasonography (US) of the abdominal wall has been used to measure peritoneal thickness non-invasively. However, direct comparison of both methods in the same patient has never been done. Furthermore, the validity of US to measure peritoneal thickness has not been investigated.

Methods

We performed 3 studies: 1) a human biopsy study to compare US measurement of peritoneal thickness with histological examination; 2) a human cadaver study to investigate the effect of removing the peritoneum on US results; and 3) a phantom study in which we used US to measure the thickness of membrane-like structures with a known thickness to investigate the influence of different US settings.

Results

The median thickness in biopsies of the peritoneum was 113 μm (interquartile range [IQR] 72 –129 μm), while this was 370 μm (IQR 324 – 458 μm) when measured by US ( p < 0.0001). The mean difference between the 2 measures was -257 μm (limits of agreement -4.6 and -511 μm). In the cadaver study, removal of the peritoneum did not have an effect on the presence or thickness of the hyperechoic line reported to represent the peritoneum. In the phantom study, results were highly dependent on frequency of the transducer, scan depth, and gain settings.

Conclusions

Ultrasonography results differ markedly from histological measurement using peritoneal biopsies. However, the hyperechoic line generated by US represents the interface between 2 neighboring tissues and not a separate morphological structure. Moreover, its thickness is greatly influenced by user-defined US settings.
Remote Patient Monitoring Program in Automated Peritoneal Dialysis: Impact on Hospitalizations
Authors: Sanabria Mauricio , Buitrago Giancarlo , Lindholm Bengt , Vesga Jasmin , Nilsson Lars-Göran , Yang Dongyan , Bunch Alfonso , Rivera Angela
Published: July 2019

Background

Automated peritoneal dialysis (APD) is a growing PD modality but as with other home dialysis methods, the lack of monitoring of patients’ adherence to prescriptions is a limitation with potential negative impact on clinical outcome parameters. Remote patient monitoring (RPM) allowing the clinical team to have access to dialysis data and adjust the treatment may overcome this limitation. The present study sought to determine clinical outcomes associated with RPM use in incident patients on APD therapy.

Methods

A retrospective cohort study included 360 patients with a mean age of 57 years (diabetes 42.5%) initiating APD between 1 October 2016 and 30 June 2017 in 28 Baxter Renal Care Services (BRCS) units in Colombia. An RPM program was used in 65 (18%) of the patients (APD-RPM cohort), and 295 (82%) were treated with APD without RPM. Hospitalizations and hospital days were recorded over 1 year. Propensity score matching 1:1, yielding 63 individuals in each group, was used to evaluate the association of RPM exposure with numbers of hospitalizations and hospital days.

Results

After propensity score matching, APD therapy with RPM ( n = 63) compared with APD-without RPM ( n = 63) was associated with significant reductions in hospitalization rate (0.36 fewer hospitalizations per patient-year; incidence rate ratio [IRR] of 0.61 [95% confidence interval (CI) 0.39 – 0.95]; p = 0.029) and hospitalization days (6.57 fewer days per patient-year; IRR 0.46 [95% CI 0.23 – 0.92]; p = 0.028).

Conclusions

The use of RPM in APD patients is associated with lower hospitalization rates and fewer hospitalization days; RPM could constitute a tool for improvement of APD therapy.
TESS Reveals that the Nearby Pisces–Eridanus Stellar Stream is only 120 Myr Old
Authors: Curtis Jason L. , Agüeros Marcel A. , Mamajek Eric E. , Wright Jason T. , Cummings Jeffrey D.
Published: July 2019

Pisces–Eridanus (Psc–Eri), a nearby (d ≃ 80–226 pc) stellar stream stretching across ≈120° of the sky, was recently discovered with Gaia data. The stream was claimed to be ≈1 Gyr old, which would make it an exceptional discovery for stellar astrophysics, as star clusters of that age are rare and tend to be distant, limiting their utility as benchmark samples. We test this old age for Psc–Eri in two ways. First, we compare the rotation periods for 101 low-mass members (measured using time-series photometry from the Transiting Exoplanet Survey Satellite) to those of well-studied open clusters. Second, we identify 34 new high-mass candidate members, including the notable stars λ Tauri (an Algol-type eclipsing binary) and HD 1160 (host to a directly imaged object near the hydrogen-burning limit). We conduct an isochronal analysis of the color–magnitude data for these highest-mass members, again comparing our results to those for open clusters. Both analyses show that the stream has an age consistent with that of the Pleiades, i.e., ≈120 Myr. This makes the Psc–Eri stream an exciting source of young benchmarkable stars and, potentially, exoplanets located in a more diffuse environment that is distinct from that of the Pleiades and of other dense star clusters.
ALMA Spectral Imaging of Titan Contemporaneous with Cassini's Grand Finale

Published: July 2019

The Cassini mission performed 127 targeted flybys of Titan during its 13 yr mission to Saturn, culminating in the Grand Finale between 2017 April and September. Here we demonstrate the use of the Atacama Large Millimeter/submillimeter Array (ALMA) to continue Cassini’s legacy for chemical and climatological studies of Titan’s atmosphere. Whole-hemisphere, interferometric spectral maps of HCN, HNC, HC3N, CH3CN, C2H3CN, C2H5CN, and C3H8 were obtained using ALMA in 2017 May at moderate (≈0.″2, or ≈1300 km) spatial resolution, revealing the effects of seasonally variable chemistry and dynamics on the distribution of each species. The ALMA submillimeter observations of HCN and HC3N are consistent with Cassini infrared data on these species, obtained in the same month. Chemical/dynamical lifetimes of a few years are inferred for C2H3CN and C2H5CN, in reasonably close agreement with the latest chemical models incorporating the sticking of C2H5CN to stratospheric aerosol particles. ALMA radial limb flux profiles provide column density information as a function of altitude, revealing maximum abundances in the thermosphere (above 600 km) for HCN, HNC, HC3N, and C2H5CN. This constitutes the first detailed measurement of the spatial distribution of HNC, which is found to be confined predominantly to altitudes above 730 ± 60 km. The HNC emission map shows an east–west hemispheric asymmetry of 13% ± 3%. These results are consistent with very rapid production (and loss) of HNC in Titan’s uppermost atmosphere, making this molecule an effective probe of short-timescale (diurnal) ionospheric processes.
Jet Geometry and Rate Estimate of Coincident Gamma-Ray Burst and Gravitational-wave Observations
Authors: Mogushi Kentaro , Cavaglià Marco , Siellez Karelle
Published: July 2019

Short gamma-ray burst (SGRB) progenitors have long been thought to be coalescing binary systems of two neutron stars (NSNS) or a neutron star and a black hole. The 2017 August 17th detection of the GW170817 gravitational-wave (GW) signal by Advanced LIGO and Advanced Virgo in coincidence with the electromagnetic observation of the SGRB GRB 170817A confirmed this scenario and provided new physical information on the nature of these astronomical events. We use SGRB observations by the Neil Gehrels Swift Observatory Burst Alert Telescope and GW170817/GRB 170817A observational data to estimate the detection rate of coincident GW and electromagnetic observations by a GW detector network and constrain the physical parameters of the SGRB jet structure. We estimate the rate of GW detections coincident with SGRB electromagnetic detections by the Fermi Gamma-ray Burst Monitor to be between ∼0.1 and ∼0.6 yr−1 in the third LIGO-Virgo observing run and between ∼0.3 and ∼1.8 yr−1 for the LIGO-Virgo-KAGRA network at design sensitivity. Assuming a structured model with a uniform ultrarelativistic jet surrounded by a region with power-law decay emission, we find the jet half-opening angle and the power-law decay exponent to be θ

 ∼ 7°–22° and s ∼ 5–30 at a 1σ confidence level, respectively.
Probing the Pulsar Population of Terzan 5 via Spectral Modeling

Published: July 2019

Terzan 5 is the only Galactic globular cluster that has plausibly been detected at very high energies by the High Energy Stereoscopic System. It has an unexpectedly asymmetric very high energy morphology that is offset from the cluster center, in addition to a large-scale, offset radio structure and compact diffuse X-ray emission associated with this cluster. We present new data from the Fermi Large Area Telescope on this source. We model the updated broadband spectral energy distribution, attributing this to cumulative pulsed emission from a population of embedded millisecond pulsars, as well as unpulsed emission from the interaction of their leptonic winds with the ambient magnetic and soft-photon fields. In particular, our model invokes unpulsed synchrotron and inverse Compton components to model the radio and TeV data and cumulative pulsed curvature radiation to fit the Fermi data, and it explains the hard Chandra X-ray spectrum via a “new” cumulative synchrotron component from electron–positron pairs within the pulsar magnetospheres that has not been implemented before. We find reasonable spectral fits for plausible model parameters. We also derive constraints on the millisecond pulsar luminosity function using the diffuse X-ray data and the Chandra sensitivity. Future higher-quality spectral and spatial data will help discriminate between competing scenarios (such as dark matter annihilation, white dwarf winds, or hadronic interactions) proposed for the broadband emission, as well as constraining degenerate model parameters.
New Probe of Gravity: Strongly Lensed Gravitational-wave Multimessenger Approach
Authors: Yang Tao , Hu Bin , Cai Rong-Gen , Wang Bin
Published: July 2019

Strong gravitational lensing by galaxies provides us with a unique opportunity to understand the nature of gravity on galactic and extra-galactic scales. In this paper, we propose a new multimessenger approach using data from both the gravitational wave (GW) and the corresponding electromagnetic (EM) counterpart to infer the constraint of the modified gravity (MG) theory denoted by the scale dependent phenomenological parameter. To demonstrate the robustness of this approach, we calculate the time-delay predictions by choosing various values of the phenomenological parameters and then compare them with that from general relativity (GR). For the third generation ground-based GW observatory, with one typical strongly lensed GW+EM event, and assuming that the dominated error from the stellar velocity dispersions is 5%, the GW time-delay data can distinguish an 18% MG effect on a scale of tens of kiloparsecs with a 68% confidence level. Assuming GR and a Singular Isothermal Sphere mass model, there exists a simplified consistency relationship between time-delay and imaging data. This relationship does not require the velocity dispersion measurement, and hence can avoid major uncertainties. By using this relationship, the multimessenger approach is able to distinguish an 8% MG effect. Our results show that the GW multimessenger approach can play an important role in revealing the nature of gravity on galactic and extra-galactic scales.
A Giant Lyα Nebula and a Small-scale Clumpy Outflow in the System of the Exotic Quasar J0952+0114 Unveiled by MUSE∗

The well-known quasar SDSS J095253.83+011421.9 (J0952+0114) at z = 3.02 has one of the most peculiar spectra discovered so far, showing the presence of narrow Lyα and broad metal emission lines. Although recent studies have suggested that a proximate damped Lyα absorption (PDLA) system causes this peculiar spectrum, the origin of the gas associated with the PDLA is unknown. Here we report the results of observations with the Multi Unit Spectroscopic Explorer (MUSE) that reveal a new giant (≈100 physical kpc) Lyα nebula. The detailed analysis of the Lyα velocity, velocity dispersion, and surface brightness profiles suggests that the J0952+0114 Lyα nebula shares similar properties with other QSO nebulae previously detected with MUSE, implying that the PDLA in J0952+0144 is covering only a small fraction of the solid angle of the QSO emission. We also detected bright and spectrally narrow C iv
λ1550 and He ii
λ1640 extended emission around J0952+0114 with velocity centroids similar to the peak of the extended and central narrow Lyα emission. The presence of a peculiarly bright, unresolved, and relatively broad He ii
λ1640 emission in the central region at exactly the same PDLA redshift hints at the possibility that the PDLA originates in a clumpy outflow with a bulk velocity of about 500 km s−1. The smaller velocity dispersion of the large-scale Lyα emission suggests that the high-speed outflow is confined to the central region. Lastly, the derived spatially resolved He ii/Lyα and C iv/Lyα maps show a positive gradient with the distance to the QSO, hinting at a non-homogeneous distribution of the ionization parameter.

We have imaged the Sunyaev–Zel’dovich (SZ) effect signals at 140 and 270 GHz toward 10 galaxy clusters with Bolocam and AzTEC/ASTE. We also used Planck data to constrain the signal at large angular scales, Herschel–SPIRE images to subtract the brightest galaxies that comprise the cosmic infrared background (CIB), Chandra imaging to map the electron temperature

of the intra-cluster medium, and Hubble Space Telescope imaging to derive models of each galaxy cluster’s mass density. The galaxy clusters gravitationally lens the background CIB, which produced an on-average reduction in brightness toward the galaxy clusters’ centers after the brightest galaxies were subtracted. We corrected for this deficit, which was between 5% and 25% of the 270 GHz SZ effect signal within R
2500. Using the SZ effect measurements, along with the X-ray constraint on

, we measured each galaxy cluster’s average line of sight (LOS) velocity v

z
within R
2500, with a median per-cluster uncertainty of ±700 km s−1. We found an ensemble-mean

v

z

of 430 ± 210 km s−1, and an intrinsic cluster-to-cluster scatter

of 470 ± 340 km s−1. We also obtained maps of v

z
over each galaxy cluster’s face with an angular resolution of 70″. All four galaxy clusters previously identified as having a merger oriented along the LOS showed an excess variance in these maps at a significance of ≃2–4σ, indicating an internal v

z
rms of ≳1000 km s−1. None of the six galaxy clusters previously identified as relaxed or plane-of-sky mergers showed any such excess variance.
Les dispenses d’instruction. De la pertinence et des dangers d’un outil régulateur
Authors: Fardet Christophe
Published: July 2019

Historiquement, les hypothèses de dispenses d’instruction n’étaient en rien un préjugement parce qu’elles n’étaient pas un refus de jugement. Il ne s’agissait que de décisions insusceptibles de recours aboutissant à un jugement final collégialement délibéré. Or, le droit positif révèle une toute autre logique en y ajoutant les ordonnances susceptibles de recours mais constituant elles-mêmes le jugement. Ainsi, de Juger sans instruire, le mécanisme s’est mué en Refus de juger sans instruire. Ce faisant, les dispenses d’instruction ne portent pas atteinte qu’au principe du contradictoire : elles interdisent au juge de connaître de tous les éléments du dossier. Deux problèmes en résultent. D’une part, l’article L. 5 CJA permet seulement la dérogation à la contradiction et non pas à l’instruction : l’absence de dérogation à l’instruction, n’exclut-elle pas toute dérogation à la nécessaire instruction des affaires ? D’autre part, dans certaines hypothèses, la dispense d’instruction peut s’inscrire dans un cumul de suppression de garanties qui, finalement, peut faire douter du respect dû au droit au recours tel qu’il est constitutionnellement et conventionnellement protégé.
L’apport des parties à la qualité de l’instruction
Authors: Caille Pascal
Published: July 2019

Sans être radicalement ignorée de la jurisprudence administrative, la qualité de l’instruction n’est pas une question essentielle pour elle. L’enjeu est pourtant double. Il en va pourtant, en premier lieu, de la durée raisonnable de jugement, en second lieu, du fond, en ce que l’instruction conditionne l’issue du litige et concourt à la qualité de la décision juridictionnelle. En effet, d’une part, par leur aptitude à les placer dans les meilleures conditions pour se faire comprendre du juge et d’éviter notamment qu’il se méprenne sur le sens des conclusions et la portée des moyens, les écritures des parties sont un vecteur de correcte appréhension de leur argumentation ; d’autre part, par leur complétude et leur cohérence, et donc leur pertinence, les écritures deviennent un vecteur du correct déroulement de la contradiction. Dans ces conditions, il est permis de dire que les parties exercent une influence sur l’intelligibilité de l’instruction. Mais les parties exercent également une influence sur la sincérité de l’instruction. Sans qu’il ne soit l’objet, dans la présente étude, de s’interroger sur l’intérêt qu’il y aurait à consacrer formellement le principe de loyauté dans le procès administratif, aujourd’hui réclamé par une part importante de la doctrine, il convient d’admettre qu’un comportement loyal des parties revêt un intérêt certain pour la qualité de l’instruction. En effet, dès lors qu’il ne saurait tout régler, les parties ne pouvant utilement combattre toutes les manœuvres adverses, le principe du contradictoire est impuissant à surmonter à lui-seul tous les obstacles. En intervenant au soutien de la contradiction, la loyauté des parties concourt ainsi à la qualité de l’instruction. Par ailleurs, en dépit de l’affirmation bien connue suivant laquelle la procédure administrative juridictionnelle est inquisitoriale, l’action du juge reste trop souvent limitée pour qu’émerge, par sa simple intervention, la « vérité » judiciaire. En adoptant un comportant loyal, chaque partie apporte sa pierre à la qualité de l’instruction et il est permis, dans ces conditions, de dire que la loyauté des parties est un complément du caractère inquisitorial de la procédure. En conséquence de tout ce qui précède, il est permis de soutenir que, variables au cours de chaque procès, la qualité des écritures et la qualité des comportements offrent une constante : en tant qu’elles influent sur son intelligibilité et sur sa sincérité, les parties influent sur la qualité de l’instruction.
Les litiges entre personnes publiques en matière d’urbanisme : l’exemple du contentieux existant autour des plans de prévention des risques d’inondation (PPRI)
Authors: de Bernardinis Christophe
Published: July 2019

La décentralisation de l’urbanisme, le développement de l’intercommunalité et l’intégration du développement durable dans toutes les politiques publiques ont fait naître des hiérarchies et des rapports juridiques complexes entre les personnes publiques et sont la source de certains litiges. Si l’urbanisme concerté est la règle, il y a des contentieux particuliers comme ceux liés à la mise en place des plans de prévention des risques d’inondation (PPRI) où existe, chez les différents acteurs, des intérêts assez antagonistes. Si le PPRI, fixé par l’Etat, doit faciliter la gestion de l’occupation des sols tout en imposant une contrainte sur l’urbanisation aux échelles locales, les conséquences catastrophiques des inondations survenues récemment confirment que l’occupation des sols, fixée par les autorités locales, ne prend pas systématiquement en compte le risque. L’échec de la collaboration initiale se matérialise à travers le contentieux de la légalité, où la combinaison des prescriptions du PPRI et de la police générale du maire (art. R. 111-2 CU) est source de conflit, mais aussi à travers le contentieux de la responsabilité lorsqu’il faut faire le bilan des différentes omissions ou actions menées. Le transfert récent de la compétence GEMAPI étant, paradoxalement, source d’une complexité accrue dans l’identification des responsabilités.
Les nouvelles routes de la soie en Méditerranée, construction d’un mythe contemporain ou réalité préoccupante ?
Authors: Tourret Paul
Published: July 2019

Depuis 2013, la Chine développe une politique relativement vaste de nouvelles routes de la soie qui inclue notamment des constructions d’infrastructures et des prises de position portuaires. Les nouvelles routes de la soie suscitent de nombreuses interrogations. C’est pourquoi, il est nécessaire de comprendre de quelles réalités, ces nouvelles routes sont le nom, et quelles sont les représentations et les mythes qui les entourent. Malgré sa distance, la Méditerranée est aussi concernée par ces nouvelles routes de la soie car elle est l’une des rives du grand marché européen et permet d’accéder aux pays de la rive Sud. Des positions portuaires ne font pas une stratégie géopolitique, mais la politique ambitieuse de Pékin peut se faire avec des outils économiques que sont les géants maritimes chinois.

Cet article explore la manière dont se sont construites et ont évolué les relations entre la Chine et trois pays du Maghreb (Maroc, Algérie et Tunisie). Il montre la place prépondérante qu’occupe l’Algérie dans les relations entre la Chine et Maghreb, hier comme aujourd’hui. Il interroge les fondements de ces relations aux intérêts multiples et les met en perspective en décrivant notamment le passage d’une solidarité aux fondements idéologiques à des relations économiques aux fondements plus pragmatiques. Inscrivant, sa présence dans sa stratégie globale, notamment via les forums sino-arabes et sino-africains et de la nouvelle route de la soie, la Chine privilégie l’échelle bilatérale dans ses relations avec les pays du Maghreb.

We propose a bootstrap‐based
calibrated projection procedure to build confidence intervals for single components and for smooth functions of a partially identified parameter vector in moment (in)equality models. The method controls asymptotic coverage uniformly over a large class of data generating processes. The extreme points of the calibrated projection confidence interval are obtained by extremizing the value of the function of interest subject to a proper relaxation of studentized sample analogs of the moment (in)equality conditions. The degree of relaxation, or critical level, is calibrated so that the function of
θ, not
θ itself, is uniformly asymptotically covered with prespecified probability. This calibration is based on repeatedly checking feasibility of linear programming problems, rendering it computationally attractive.

Nonetheless, the program defining an extreme point of the confidence interval is generally nonlinear and potentially intricate. We provide an algorithm, based on the response surface method for global optimization, that approximates the solution rapidly and accurately, and we establish its rate of convergence. The algorithm is of independent interest for optimization problems with simple objectives and complicated constraints. An empirical application estimating an entry game illustrates the usefulness of the method. Monte Carlo simulations confirm the accuracy of the solution algorithm, the good statistical as well as computational performance of calibrated projection (including in comparison to other methods), and the algorithm's potential to greatly accelerate computation of other confidence intervals.

At most of elementary school, students learn cube nets from a books and teacher stories. As a three dimentional structure, a cube alsochapter should be taught using three dimentional media. It helps students to imagine the concept of the chapter. A cube has eleven nets, therefore it may be hard to get all of the nets and present them as media in front of students. This paper proposes a media education for cube nets learning. The media is software that developed for desktop utilizing. The software product from this method is tested to elementary school student. A pre test and post test is applied to know student’s skills about cube nets, before and after they used the application. Using Wilcoxon test, the result shows that p-value (0.017) < α (0.05). In other word, the students gain more scores after they use the educational media. The students are also given a questionnaire to valuate the application. From the questionnaire, conclude that the motivational affordance gain 87.14% while the physicological outcome gets 91.67%. Whereas the students give 90.57% for behavioural outcome

Classroom Response Systems is a scanner system in the form of technology that is used in the classroom, which allows students to answer a question with an input directly inputted into the data, so that the application of learning outcome measurement becomes effective and efficient. This study uses qualitative methods and is implemented in 120 students and is a formative research. This study describes the use of Classroom Response Systems (CRS) when measuring student learning outcomes. The research subjects were students of the Mathematics Education and Elementary School Teacher Education Department who had heterogeneous abilities. Research findings show that students consider CRS can improve class dynamics in theoretical lectures. On the other hand, almost all students have agreed with the assertion that CRS is easy to use, although some of them have warned that recipients do not always record their responses.

Published: July 2019

Massive open online courses (MOOC) transcends the time and space limits of traditional classroom teaching, and promotes the sharing of teaching resources. However, the effect of this emerging teaching mode is yet to be determined. In this paper, the big data analysis is introduced to evaluate the MOOC teaching quality. Taking several online courses as an example, a video player was de-signed to compute the learning time using the Hadoop platform. On this basis, the author constructed a teaching quality evaluation platform. In addition, the learning cost coefficient was calculated by the naive Bayesian model, and the evaluation results were analysed in details. The research findings shed practical new light on the evaluation of MOOC teaching quality.

INCORPORATING SUSTAINABILITY PRINCIPLES INTO ARCHITECTURAL DESIGN EDUCATION: RESULTS OF AN EXPERIMENTAL DESIGN STUDIO
Authors: Mohamed Kamal Eldin , Elias-Ozkan Soofia Tahira
Published: July 2019

Design is a structured process or a tactical guideline to accomplish a unique expectation of a product, while a design studio is the environment where students are taught the skills to design the product, which may be a building. Hence, the design studio course is the most important component of the architectural education curriculum; it is where the students get an opportunity to apply the theoretical knowledge gained through lecture-based courses. Yet most theory is not put into practice; consequently, the principles of sustainable design solutions are developed. There is an urgent need to teach future architects how to integrate sustainable design principles into their projects in order to prevent or mitigate environmental degradation due to the negative impacts of building projects. This experimental study initiated a new design studio pedagogy and a novel teaching structure for integrating sustainability principles into the architectural design projects of 3rd year students. It also evolved a testing method to assess the success of the new pedagogy and the students' final design projects. This paper presents the results of the experimental design studio and delivers recommendations for subsequent sustainable design studio courses.

Published: July 2019

This paper discusses the application of Integrated Design Process for the design of low-cost housing in Chile. It aims to question common practice for the development of housing based on prescriptive regulations and non-interdisciplinary work, which has resulted in poor quality building requirements. The first stage consisted in defining performance requirements for aspects such as energy demand, U value, air tightness and indoor air quality for a specific case of low-cost houses located in the city of Temuco. An integrated design process was carried out by an interdisciplinary team of professionals specialized in each of the performance aspects that were taken into account. The construction and post-occupancy stages were characterized by verifying the performance requirements, which resulted in a low-cost house prototype that included strategies for energy efficiency and a healthy indoor environment.

Authors: Pushkar Svetlana , Verbitsky Oleg
Published: July 2019

Leadership in Energy and Environmental Design Commercial Interiors (LEED-CI) is more relevant to interior design, which, according to the sharing layer concept, differs from exterior design (which is usually evaluated with the LEED New Construction sub-scheme). LEED-CI requires separate empirical analyses of LEED-CI certified buildings to further improve this sub-scheme. Therefore, in this study, Silver and Gold projects certified under LEED-CI-2009 in 14 US states were considered. Three project performance analyses, (i) certification, (ii) category, and (iii) cross-certification, were studied. The following results were revealed: (i) the range of the medians for Silver- and Gold-certified projects were 51–57 pts and 62–71 pts, respectively; (ii) in both Silver- and Gold-certified projects, Sustainable Sites (SS), Water Efficiency (WE), and Innovation in Design (ID) were the best-performing; Energy and Atmosphere (EA) and Indoor Environmental Quality (EQ) were intermediate-performing; and Material and Resources (MR) was the worst-performing categories; and (iii) in Silver-Gold cross-certification, category-focused (in 10 of 14 states) and category-unfocused (in four of 14 states) strategies were determined; in the category-focused strategy, the highest popular category was EA; the intermediate popular categories were WE, MR, and ID; and the lowest popular category was SS. Pooling all projects and all states into one frame can lead to the obscurement of the actual LEED-CI-2009 strategy(ies) in the transition from Silver to Gold certification in the US.

Published: July 2019

Electronic word of mouth (e-WOM) is rapidly becoming an empowering tool for consumers to express their experiences on services or products, on social media or other platforms. Beyond the obvious implications of such content to potential consumers, interest is also high among researchers, industry players, and other stakeholders who strive to analyze before-and-after sales expectations, emotions, and perceptions of customers. The need to find efficient ways of extracting and then analyzing online content rendered the reuse of tools and methodologies initially applied in other fields as well as the development of new approaches. In this chapter, the authors identify high-impact scientific work related to e-WOM and point out the analytical methods for analyzing e-WOM content. Furthermore, this chapter refers to the most relevant studies employing such methods and their findings. More specifically, it discusses clustering, sentiment analysis, supervised and unsupervised machine learning, lexicon-based approaches, corpus-based approach, summarization and predicting, and regression analysis.
