Half-Maxwell fisheye lens with photonic crystal waveguide for the integration of terahertz optics
Authors: Headland Daniel , Fujita Masayuki , Nagatsuma Tadao
Published: January 2020

Currently, optics such as dielectric lenses and curved reflector dishes are commonplace in terahertz laboratories, as their functionality is of fundamental importance to the majority of applications of terahertz waves. However, such optics are typically bulky and require manual assembly and alignment. Here we seek to draw inspiration from the field of digital electronics, which underwent rapid acceleration following the advent of integrated circuits as a replacement for discrete transistors. For a comparable transition with terahertz optics, we must seek mask-oriented fabrication processes that simultaneously etch multiple interconnected integrated optics. To support this goal, terahertz beams are confined to two dimensions within a planar silicon slab, and a gradient-index half-Maxwell fisheye lens serves to launch such a slab-mode beam from a terahertz-range photonic crystal waveguide that is coupled to its focus. Both the optic and the waveguide are implemented with through-hole arrays and are fabricated in the same single-etch process. Experiments indicate that a slab-mode beam is launched with ∼86% efficiency, over a broad 3 dB bandwidth from ∼260 to ∼390 GHz, although these reported values are approximate due to obfuscation by variation that arises from reflections within the device.
Frequency induced rotation of high-contrast angular intensity fringes from an uncoated SPP device
Authors: Rumala Yisa S. , McMahon Matthew D.
Published: January 2020

High-contrast angular intensity fringes are generated by reflecting laser light from an uncoated spiral phase plate (SPP) device for the first time, to the best of our knowledge. As the laser frequency going into the device is tuned, the fringes rotate. Measured transverse fringe patterns match their theoretical predicted values. They have unity contrast, and their measured intensity varies with laser frequency in a fashion similar to a Fabry–Perot etalon. This effect can be used to enable new miniature devices for angle metrology, imaging, and microscopy.
Parallel structured optical fiber in-line Fabry–Perot interferometers for high temperature sensing
Authors: Cui X. L. , Zhang Hua , Wang D. N.
Published: January 2020

We propose and demonstrate parallel structured optical fiber in-line Fabry–Perot interferometers for high temperature sensing. The device consists of three Fabry–Perot cavities in parallel connection, which allows three independent fringe patterns superimposed at its output, and, as a result, a number of dominant fringe peaks/dips appear, thus enabling unambiguous measurement in a large range. The device is featured with compact size, robust structure, and excellent high temperature sustainability, which makes it promising in extreme environment monitoring.

Authors: Ren Xinyi , Dai Hu , Li Detian , Huang Kun , Hu Mengyun , Lv Tianjian , Yan Ming , Zeng Heping
Published: January 2020

In this Letter, we utilize an acoustic-optic frequency shifter in a feedforward manner for automatic interpolation of dual-comb spectroscopy, where frequency tuning can be achieved at 5.45 THz/s with the step size precisely locked to the line spacing (54.5 MHz) of a referenced optical comb without complicated electronics or control programs. Our dual-comb spectrometer involves two near-infrared electro-optic combs at 25 GHz line spacings, nonlinearly converted into the mid-infrared region, revealing fundamental absorption lines of methane gas at 54.5 MHz resolution within a spectral range from 88.04 to 89.04 THz. The method and the system may be useful in many applications, including gas sensing.

Published: January 2020

We present a novel adaptive liquid lens actuated by electrofluid. The deformation of electrofluid under the combined action of vertical electric fields and magnetic fields controls the hydraulic pressure in the lens chamber. Both the study of electrohydrodynamics and the study of optical properties of the prototype have been carried out. The measured focal length of the liquid lens decreases from 34.55 mm to 5.12 mm, as the current increases from

Published: January 2020

Quasi-phase-matched interactions in waveguides with quadratic
nonlinearities enable highly efficient nonlinear frequency conversion.
In this paper, we demonstrate the first generation of devices that
combine the dispersion engineering available in nanophotonic
waveguides with quasi-phase-matched nonlinear interactions available
in periodically poled lithium niobate (PPLN). This combination enables
quasi-static interactions of femtosecond pulses, reducing the pulse
energy requirements by several orders of magnitude compared to
conventional devices, from picojoules to femtojoules. We
experimentally demonstrate two effects associated with second harmonic
generation (SHG). First, we observe efficient quasi-phase-matched SHG
with

<

f
J

of pulse energy. Second, in the limit
of strong phase-mismatch, we observe spectral broadening of both
harmonics with as little as 2 pJ of pulse energy. These results lay a
foundation for a new class of nonlinear devices, in which
coengineering of dispersion with quasi-phase-matching enables
efficient nonlinear optics at the femtojoule level.

A gestão democrática da escola pública em contextos de reformas educacionais locais: Estudo comparado entre Brasil e Espanha
Authors: Batista Neusa Chaves , Pereyra Miguel A.
Published: January 2020

A gestão democrática, como modo de organização da escola pública, pode ser traduzida, em sua historicidade contemporânea, como uma ação coletiva que exige mudanças na estrutura autocrática e hierárquica da unidade escolar. Neste artigo analisamos o processo de construção da legislação sobre gestão escolar democrática em contextos de reformas educacionais locais, tomando por base os casos brasileiro e espanhol. Metodologicamente, entendemos a legislação educacional como documentos que incorporam discursos revestidos de autoridade legítima, especialmente de Estado, que difundem concepções de mundo fruto de disputas por hegemonia no campo das políticas educacionais. Em termos de resultados, nosso estudo aponta que, ao longo do processo de produção de legislação para a gestão escolar democrática, os dois países que investigamos apresentam avanços e recuos em relação tanto à especificação dos atores escolares que deveriam participar nos processos de tomada de decisões sobre as questões escolares, quanto sobre quais seriam as instâncias de participação na gestão escolar.
Towards bridging theory and practice

Published: January 2020

Graph is a ubiquitous structure representing entities and their relationships applied in many areas such as social networks, web graphs, and biological networks. One of the fundamental tasks in graph analytics is to investigate the relations between two vertices (e.g., users, items and entities) such as how a vertex
A
influences another vertex
B
, or to what extent
A
and
B
are similar to each other, based on the graph topology structure. For this purpose, we study the problem of hop-constrained
s-t
simple path enumeration in this paper, which aims to list all simple paths from a source vertex
s
to a target vertex
t
with hop-constraint
k.
We first propose a polynomial delay algorithm, namely BC-DFS, based on barrier-based pruning technique. Then a join-oriented algorithm, namely JOIN, is designed to further enhance the query response time. On the theoretical side, BC-DFS is a polynomial delay algorithm with
O
(
km
) time per output where
m
is the number of edges in the graph. This time complexity is the same as the best known theoretical result for the polynomial delay algorithms of this problem. On the practical side, our comprehensive experiments on 15 real-life networks demonstrate the superior performance of the BC-DFS algorithm compared to the state-of-the-art techniques. It is also reported that the JOIN algorithm can further significantly enhance the query response time.
Operationalizing individual fairness with pairwise fair representations
Authors: Lahoti Preethi , Gummadi Krishna P. , Weikum Gerhard
Published: January 2020

We revisit the notion of individual fairness proposed by Dwork et al. A central challenge in operationalizing their approach is the difficulty in eliciting a human specification of a similarity metric. In this paper, we propose an operationalization of individual fairness that does not rely on a human specification of a distance metric. Instead, we propose novel approaches to elicit and leverage side-information on equally deserving individuals to counter subordination between social groups. We model this knowledge as a fairness graph, and learn a unified Pairwise Fair Representation (PFR) of the data that captures both data-driven similarity between individuals and the pairwise side-information in fairness graph. We elicit fairness judgments from a variety of sources, including human judgments for two real-world datasets on recidivism prediction (COMPAS) and violent neighborhood prediction (Crime & Communities). Our experiments show that the PFR model for operationalizing individual fairness is practically viable.

A non-uniform dip slip formula to calculate the coseismic deformation: Case study of Tohoku Mw9.0 Earthquake
Authors: Zhang Yongzhi , Wang Yipeng , Duan Hurong , Gao Yang , Jiao Jiashuang
Published: January 2020

The distribution of slip faults along the fault plane plays a special role in the kinetic pattern of tectonic deformation. To better understand the coseismic deformation and geodynamics of the earthquake, this paper applied the pile-up theory and derived an analytical formula to describe the non-uniform slip distribution along the fault width. To validate the new formula, it was tested with the coseismic displacements at the global positioning system (GPS) stations for the Tohoku earthquake in 11 March, 2011. Then, the computed horizontal and vertical displacements calculated using NDSM were compared to back-slip model (BSM) using GPS data obtained from the Jet Propulsion Laboratory (JPL). Finally, the theoretical analysis revealed that the analytical formulas derived here can be perceived as the expansion and perfection of the uniform dislocation model. Meanwhile, our results showed that the characteristics of the spatial distribution deformation from NDSM are similar to those derived by GPS measurements. Furthermore, the near-field RMS errors indicated that the horizontal displacements estimated using NDSM is 27.5%, and 35.6% for the vertical components. Our new formulas and findings could assist better portray the crustal deformation in some region and geodynamics in specific earthquake.
The Impacts of Climate Change on Maximum Daily Discharge in the Payab Jamash Watershed, Iran
Authors: Parandin Farzad , Khoorani Asadollah , Bazrafshan Ommolbanin
Published: January 2020

One of the most crucial consequences of climate change involves the alteration of the hydrologic cycle and river flow regime of watersheds. This study was an endeavor to investigate the contributions of climate change to maximum daily discharge (MDD). To this end, the MDD simulation was carried out through implementing the IHACRES precipitation-runoff model in the Payyab Jamash watershed for the 21st century (2016-2100). Subsequently, the observed precipitation and temperature data of the weather stations (1980-2011) as well as 4 multi-model outputs of Global Climate Models (GCMs) under the maximum and minimum Representative Concentration Pathways (RCPs) (2016-2100) were utilized. In order to downscale the output of GCMs, Bias Correction (BC) statistical method was applied. The projections for the 21st century indicated a reduction in Maximum Daily Precipitation (MDP) in comparison with the historic period in the study area. The average projected MDP for the future period was 9 mm/day and 5 mm/ day under 2.6 and 8.5 RCPs (4.6% and 2.6% decrease compared with the historical period), respectively. Moreover, the temperature increased in Jamash Watershed based on 2.6 and 8.5 RCPs by 1∘C and 2∘C(3.7% and 7.4% increase compared with the historical period), respectively. The findings of flow simulation for the future period indicated a decrease in MDD due to the diminished MDP in the study area. The amount of this decrease under RCP8.5 was not remarkable (0.75 m3/s), whereas its value for RCP2.6 was calculated as 40m3/s (respectively, 0.11% and 5.88% decrease compared with the historical period).

Prescription Opioid Misuse and Risky Adolescent Behavior
Authors: Bhatia Devika , Mikulich-Gilbertson Susan K. , Sakai Joseph T.
Published: January 2020

OBJECTIVES:

Misuse of opioid medications (ie, using opioids differently than how a doctor prescribed the medication) is common among US adolescents and associated with preventable health consequences (eg, severe respiratory depression, seizures, heart failure, and death).1 New guidelines and recommendations have made providers more attuned to overprescribing and more vigilant about screening for opioid misuse.2 We hypothesized that youth who misused prescription opioids were more likely to report engaging in a broad range of other risky behaviors.

METHODS:

We used the Centers for Disease Control and Prevention’s 2017 Youth Risk Behavior Surveillance Survey (n = 14 765), a cross-sectional, nationally representative survey of high school students. Students were sampled by using a 3-stage random cluster design. We conducted weighted logistic regressions to determine the strength of the association between our independent variable, ever misusing prescription opioids, and 22 dependent variables in the following categories: risky driving behaviors (4 variables), violent behaviors (3 variables), risky sexual behaviors (4 variables), substance use (10 variables), and suicide attempt (1 variable).

RESULTS:

In 2017, 14% of US adolescents reported ever misusing opioids. Those who misused prescription opioids were significantly more likely to have engaged in all 22 risky behaviors (adjusted odds ratios ranged from 2.0 to 22.3; P < .0001 for all tests) compared with other adolescents.

CONCLUSIONS:

Adolescents reporting ever misusing prescription opioids were more likely to have engaged in a broad range of risky behaviors. Health care providers screening for prescription opioid misuse may be ideally positioned to identify these high-risk youth and initiate early interventions.

Application of Target Costing method in the Hospitality Industry
Authors: Pajrok Andor
Published: January 2020

Traditional approaches to managing costs are based on the costs that are the result of existing capabilities and resources in the company. Adding to these costs a specified margin or profit, leads to the sales price. If the market is not ready to accept such a selling price, managers need to find opportunities for rationalization and cost reduction. Target cost management begins the process of managing the sales price and the planned profit that the market can accept, and only then is it possible to determine the cost of the product. In the planning phase of the product and the manufacturing process the approach is to finding a method to lower costs and to reduce them as much as possible. The aim this of study is to investigate the application of target (strategy) cost accounting methods in the Hospitality Industry.
How women, designated as poor, reconstruct identities and ways of life? — the PRSI or the processes of re-qualifying social-identity
Authors: De Fátima Toscano Maria
Published: January 2020

The sociological qualitative analysis of social identities and of the meanings of social action, the grounded theory and the ‘writing as analytical praxis qualitative-method’ have permitted me the co-creation of women biographies of un-qualifying/re-qualifying — oral discourses about their migration at the Pays Basque. I argue that the “poverty studies traditions” reproduce and contains seven (7) epistemological obstacles and formulations on negative terms, and I underline theoretical contributors to the Identities Sociology, discussing the oppositions “personal/social” (Social-Psi), and “determined-objectives identities/assumed-subjective identities” (Karl Marx, Émile Durkheim, Talcott Parsons and Pierre Bourdieu). So, I define “social identities” as the way the social-actor becomes a social-sujet (on the tradition of Touraine), considering three components (to explain). Defining oral discourses as the condition to co-construct the social experience, I identify and explain, at the re-qualifying processes: 1) several reaction phases – on positive terms – and social-identities territory’s implicated, as multiple meanings of the social action and identity-strategies (Risc, Strategic-Sacrifice); 2) four identity resources-capitals negotiated, affected, connected or stimulated.
Cost-effectiveness of alternative strategies for vaccination of adolescents against serogroup B IMD with the MenB-FHbp vaccine in Canada
Authors: Breton Marie-Claude , Huang Liping , Snedecor Sonya J. , Cornelio Noelle , Fanton-Aita Fiorella
Published: January 2020

Objective

Serogroup B meningococci (MnB) are now the largest cause of invasive meningococcal disease (IMD) in Canada. We assessed the clinical and economic impact of 3 adolescent MenB-FHbp immunization strategies.

Methods

A population-based dynamic transmission model was developed to simulate the transmission of MnB among the entire Canadian population over a 30-year time horizon. Age group-based IMD incidence, bacterial carriage and transmission, disease outcomes, costs, and impact on quality of life were obtained from Canadian surveillance data and published literature. The vaccine was assumed to provide 85% protection against IMD and 26.6% against carriage acquisition. The model estimated the impact of routine vaccination with MenB-FHbp in 3 strategies: (1) age 14, along with existing school-based programs, with 75% uptake; (2) age 17 with 75% uptake, assuming school vaccination; and (3) age 17 with 30% uptake, assuming vaccination outside of school. Costs were calculated from the Canadian societal perspective.

Results

With no vaccination, an estimated 3974 MnB cases would be expected over 30 years. Vaccination with strategies 1–3 were estimated to avert 688, 1033, and 575 cases, respectively. These outcomes were associated with incremental costs per quality-adjusted life-year of $976,000, $685,000, and $490,000.

Conclusions

Our model indicated that if the vaccine reduces risk of carriage acquisition, vaccination of older adolescents, even at lower uptake, could have a significant public health impact. Due to low disease incidence, MnB vaccination is unlikely to meet widely accepted cost-effectiveness thresholds, but evaluations of new programs should consider the overall benefits of the vaccination.

Results: The self-care behaviors of the renal dialysis patients showed a statistically significant positive correlation with autonomous motivation (r=.33, p<.001), health provider’s support (r=.34, p<.001), and family support (r=.40, p<.001), a negative correlation with depression (r=-.31, p=.001). A stepwise regression analysis was performed to examine the factors affecting self-care behaviors in renal dialysis patients. Family support, depression and autonomous motivation were significant predictors of self-care behaviors in renal dialysis patients, and these variables accounted for 23.5% of self-care behaviors. Conclusions: This study was to find out the relationship between self-care behaviors related variables in renal dialysis patients and to provide basic data for management, maintenance, and promotion of self-care behaviors. Family support, depression and autonomous motivation of renal dialysis patients were most important variables related to self-care behaviors. Therefore, it is necessary to develop a plan that can intervene in depression in renal dialysis patients early and effectively to improve family support and subject’s autonomous motivation.

Authors: Kim Hyun-Ah , Lee Jayoung
Published: January 2020

Background: The purpose of this study was to examine the mediating effects of achievement goals (performance approach goal, mastery approach goal, performance avoidance goal) on the link between role stress and burnout and engagement. Methods: A total 224 non-commissioned officers agreed to the purpose of this study were participated. A correlation analysis was performed by using SPSS 21.0, and Structural Equation Modeling (SEM) was performed by using AMOS 20.0. Results: This study were as follows. As a result of comparing the research model including the performance approach goal and the competition model except the performance approach goal, the competition model was excellent. In addition, performance avoidance goal was partially mediated in the relationship between role stress and burnout. In addition, the mastery approach goal was partially in the relationship between role stress and engagement. Conclusions: The results imply that improving mastery approach goal and decreasing performance avoidance goal is very important for non-commissioned officers. Therefore, the military authorities should develop various strategies to decrease performance avoidance goal and improve the mastery approach goal.

Bu çalışmanın amacı
ülkemizdeki antrenörlerin spor psikolojisi bilgi düzeylerine ilişkin
algılarının belirlenmesi ve antrenörlerin bu algılarının spor psikolojisi
danışmanlığına yönelik tutumları ile ilişkisinin incelenmesidir. Çalışmaya
farklı spor branşlarından toplam 313 antrenör katılmıştır. Antrenörlerin spor
psikolojisine ilişkin bilgi düzeyleri araştırmacılar tarafından ilgili
literatürden hareketle geliştirilen anket ile ölçülmüştür. Antrenörlerin spor
psikolojisi hizmetlerine yönelik tutumlarının ölçümü için ise Antrenörlerin
Spor Psikolojisi Tutumları Ölçeği Kısaltılmış Versiyonu (Shortened Version of
the Sport Psychology Attitudes Revised Coaches – 2, SPARC-2) Türkçe’ye
uyarlanarak kullanılmıştır. Bulgular tüm antrenörlerin spor psikolojisi
bilgilerinin sınırlı olduğunu ve daha üst antrenörlük kademesine sahip
antrenörlerin spor psikolojisi hizmetlerine daha açık olduklarını ortaya
koymuştur. Bu sonuçlar ülkemizde spor psikolojisi hizmetlerinin arttırılması
adına antrenörlerin spor psikolojisi eğitimlerinin önemini ortaya koymaktadır.
Olumlu ve Olumsuz Mesaj Stratejileri Bağlamında Siyasi Liderin Seçmen Algısı Üzerine Etkisi: 31 Mart 2019 Mahalli İdareler Seçimi Örneği
Authors: CAN Efe Numan , GÜLLÜPUNAR Hasan
Published: January 2020

Liderlik en genel tanımıyla belirli bir amaç için bir grup insanı bir araya getirme, etkileme,
yönlendirme ve harekete geçirme kabiliyetidir. Siyasi arenada da liderlik en önemli faktörlerden
biridir. Ülkemiz siyasi tarihinin her aşamasında siyasi liderlerin olumlu ya da olumsuz etkileri
olduğunu söylemek yanlış olmayacaktır. Bilhassa seçim süreçlerinde halkın karşısına çıkan ve
onları ikna edip desteklerini almaya çalışan siyasi liderlerin mücadeleleri seçim sonuçlarına
doğrudan etki etmiştir. Seçim sürecinde kullanılan stratejiler de savaş meydanlarında
uygulananları aratmamıştır. Muktedir olmak isteyen siyasi aktörler bu bağlamda birbirlerine
saldırmaktan veya negatif söylemlerde bulunmaktan kaçınmamışlardır. Bunun için her türlü
siyasal iletişim faaliyeti kullanılmıştır. Bu faaliyetlerde olumlu ve olumsuz mesaj stratejileri
de uygulanmıştır. Her toplum tarzı ne olursa olsun bir yönetim biçimine sahiptir. Bazı ülkeler
güçlü seçim sistemlerine sahipken bazılarında saltanatlar, kabilecilik ya da diktatörlük hüküm
sürmektedir. Demokratik sistemin yerleştiği toplumlarda iktidar, temsil yoluyla siyasal aktörlere
devredilir. Bunun için seçimler yapılır ve çoğunluğun desteğini arkasına alan siyasi partiler
belirli süreler için göreve gelirler. Bu süreç, birçok faktörün bir araya gelmesiyle işleyen bir
mekanizmadır. Bu faktörler içerisinde siyasal liderliğin rolü oldukça önemli bir yer tutmaktadır.
Özellikle Türkiye gibi siyasal katılım oranın yüksek olduğu ülkelerde siyasal liderler, çoğunlukla
partileriyle özdeşleştirilmekte hatta kimi durumlarda partilerinin bile önünde yer almaktadır.
Bu kapsamda Ak Parti ve CHP’nin 31 Mart 2019 Mahalli İdareler Seçimine yönelik yayınladıkları
seçim beyannamelerinden elde edilen olumlu ve olumsuz mesajlar nitel içerik analizi yöntemiyle
incelenmiş ve ölçek geliştirilerek katılımcılara yöneltilmiştir. Aksaray Üniversitesi’nin çeşitli
bölümlerinde öğrenim gören 430 öğrenciyle yapılan araştırmada yapılan analizler neticesinde
siyasi liderin kullandığı mesaj stratejilerinin katılımcılar üzerinde etkili olduğu anlaşılmaktadır.
Reklamdan Kaçınma Bağlamında Geleneksel ve Modern Film İzleme Ortamlarının Genç İzleyiciler Üzerinden Karşılaştırılması: Netflix ve Sinema Salonları Örneği
Authors: AKINCI Semra , BAŞER Emrah
Published: January 2020

Gelişen teknoloji gündelik hayat pratiklerimizi büyük bir hızla değiştirmeye ve dönüştürmeye devam etmektedir. Söz konusu alanlardan biri de modern bireyin film izleme alışkanlığı olarak ele alınabilir. Yeni iletişim teknolojilerinin getirdiği bir takım olanaklar dâhilinde birey film izleme eylemini farklı şekillerde gerçekleştirebilme şansına sahip olmuştur. Film izlemek için de sinemaya gitme zorunluluğu, teknolojik gelişim sürecinin bir çıktısı olarak değerlendirilebilecek online içerik sağlayıcı platformlar aracılığıyla ortadan kalkmıştır. Son yıllarda popülerliği hızla artan online içerik sağlayıcı platformlar günümüz bireyine istediği filmi, istediği zamanda, istediği yerde izleyebilme olanağı sunmuştur. Söz konusu platformlardan içerik çeşitliliği, erişilebilirliğinin yüksek olması ve servis sağlama kalitesinin niteliğiyle öne çıkanlardan belki de ilk akla geleni Netflix’tir. Netflix’i öne çıkaran ve çekici kılan bir takım özellikleri bulunmaktadır. Bu çekici faktörlerden birisi reklamdan kaçınma olanağıdır. Bundan hareketle bu çalışmada, Netflix’in gençlerin film izleme alışkanlıkları üzerinde nasıl bir değişime sebep olduğu, reklamdan kaçınma isteğinin gençlerin Netflix abonesi olmaları noktasında ne tür bir etkiye sahip olduğu, Netflix ve sinema karşılaştırıldığında gençlerin günümüz dünyasında bu iki film izleme ortamına dair genel görüşlerinin ortaya çıkarılması amaçlanmaktadır. Bu amaçla; yarı yapılandırılmış görüşme tekniği, veri toplama aracı olarak kullanılmıştır ve Netflix aboneliği bulunan gençler araştırma örneklemine dâhil edilmiştir. Bu bağlamda, on yedi genç ile derinlemesine görüşme yapılmıştır. Reklamdan kaçınma eğiliminin Netflix abonesi olma üzerinde etkili olması bu çalışmada ulaşılan en önemli sonuçtur.

This special issue proposes a reexamination of public service broadcasting (PSB) in the light of the most recent technological, political and economic developments. Traditional public service broadcasters, ideally designed to serve citizens rather than consumers to inform the national conversations in well-informed democracies, face the double challenge of commercialization (since the 1980s) and digitization (since the 1990s). The question of their survival in this context has been posed again and again. The need for a redefinition seems inevitable.
Public Broadcasting Footage in the Commons

Around the release of the documentary series The Mind of the Universe (2017), public broadcaster VPRO and The Netherlands Institute for Sound and Vision collaborated to distribute the raw materials shot for the series to be released under open licenses. This article reflects on those experiences and gives recommendations for the various stages of production for open licensing. It aims to lower the threshold for other public broadcasters that wish to publish materials in the commons.
Audience Participation in PSM from a Media-centric to a Society-centric Approach
Authors: Vanhaeght Anne-Sofie
Published: January 2020

Audience participation in production of public service media programs appears to achieve objectives that are more often media-centric than society-centric. The Monitor, a journalism program of Dutch public broadcaster NPO chooses not to focus on participation in production but on participation in the information-gathering phase. We investigate whether and how participation in this stage involves society-centric participation. We carry out expert interviews with the journalists, questioning their intentions and how they evaluate audience input in terms of societal objectives. In the conclusion, we discuss how participation in pre-production can help journalists to step out of their bubble.
A acolhida humanitária com a lei 13.445/17: rumo a um tratamento digno ao migrante forçado no Brasil
Authors: Salles Denise Mercedes Nuñez Nascimento Lopes , Riggo Renata Freitas Quintella , Santos Lara De Freitas
Published: January 2020

O número de migrantes e refugiados cresceu vertiginosamente nos últimos anos no Brasil. Entre diversos fluxos de migrantes forçados, encontram-se os provenientes de contextos apontados como de graves crises humanitárias. A finalidade desta análise é compreender a política de emissão de vistos humanitários à luz da nova lei de migração brasileira e, assim, considerar em que medida esta mudança legislativa traz benefícios em termos de uma política de direitos humanos a estes novos migrantes de sobrevivência. Dessa forma, parte-se da caracterização da migração humanitária no mundo atual e da análise da mudança de legislação migratória no Brasil; que passou de uma ótica de securitização para uma perspectiva de direitos humanos em relação ao migrante. Em seguida, recuperam-se as ações humanitárias do governo Dilma com relação aos haitianos e sírios até a forma como foi aprovada a previsão legal deste tipo de visto na Lei 13445/17. Por fim, também será debatido o Decreto 9.199/17 que, ao regulamentar a nova legislação, deixou de tratar da forma específica de efetivação destes tipos de vistos e a acolhida humanitária, criando um paradoxo em relação a perspectiva da lei vigente no país.
