Free Trade Agreements - Boon or Bane?": Through the Lens of PACER
Authors: Kelsey Jane
Published: September 2019

This paper examines three dimensions of the Pacific islands’ relationship with Australia and New Zealand under the Pacific Agreement on Closer Economic Relations (PACER): first the context, where Pacific governments appear increasingly nervous about free trade negotiations, but believe they have few alternatives; second, how the complex and opaque legal framework of PACER and onerous requirements for WTO compatibility set the terms for future trade negotiations with Australia and New Zealand; and third, the inter-relationship between PACER and the Pacific Plan. It concludes that free trade negotiations risk determining the development options for the Pacific islands and leave no room for Pacific governments or people to explore genuine development alternatives.
The Democratic Challenge of Incorporation: International Human Rights Treaties and National Constitutions
Authors: Harrington Joanna
Published: September 2019

According to Canadian Supreme Court Justice Claire L’HeureuxDubé, the global judicial community is engaged in a process of dialogue, especially in cases involving the determination of constitutionally protected human rights. However, as this author notes, if there is a process of dialogue taking place, it does not always include the international treaty monitoring bodies supported by the United Nations, even when there is a treaty link between the international body and the domestic state. The author considers the approach taken by courts in South Africa, the United Kingdom and Ireland with respect to the judicial consideration of international human rights decisions, linking the prospects for dialogue to the express mandates to consider such case law within their constitutions, while contrasting the experience with that of Canada and New Zealand, where no such express imperative exists. The author concludes by suggesting that such a constitutionallydeterminedapproach may well be the most democratic means of reconciling a state’s international commitments with its domestic law.
Regionalising International Refugee Law in the European Union: Democratic Revision or Revisionist Democracy?
Authors: McAdam Jane
Published: September 2019

This paper questions whether the process of harmonisation of the European Union’s asylum laws has strengthened the region’s commitment to international law and international standards, or has instead diluted them in order to accommodate regional (and domestic "democratic") concerns about forced migration. Harmonisation has taken place in a political environment that is suspicious of asylum seekers, that seeks restrictive entrance policies and that is wary of large numbers of refugees. This paper argues that such factors have heavily influenced the scope of the common asylum laws – who is eligible for protection – and the rights to which beneficiaries are entitled – what that protection actually is. It looks in particular at the confinement of protection to "third country nationals", a restriction which contravenes the 1951 Refugee Convention and denies international protection to groups within the EU such as the Roma, whose discrimination is welldocumented and has historically led to many being recognised as refugees. Furthermore, the paper considers that the EU citizen’s right to free movement is not synonymous with a right to residence, and is especially complicated for nationals of the 12 new accession States. It argues that harmonisation has occurred at the expense of a comprehensive and systematic analysis of international law, responding instead to "democratic" political compromise and pragmatism.
Democratic Custom v International Customary Law
Authors: Roughan Nicole
Published: September 2019

This article responds to the criticism that customary international law is undemocratic, by arguing that the criticism takes too narrow a view of conceptions of democracy and custom.  The author suggests that democracy can be conceived as a process of participation rather than representation; and presents a conception of "compound custom" which combines the elements of custom as a source of law, as a mode of rights, and as a foundation of interaction.  With this conception of compound custom in mind, customary international law has a greater democratic potential.
For the Rights of "Nobodies": the Globalising Tension between Human Rights and Democracy
Authors: Teraya Koji
Published: September 2019

In this article, the author suggests that democracy should not be accepted as a wholly positive ideal without question, examining in particular the assumption that democracy always ensures the protection of human rights. To highlight this concern, the author focuses on the creation of “Nobodies” – individuals within democratic states that are expelled and, as a result, are deprived of human rights, including those who are deprived of nationality and those who are expelled by the operation of law, concluding that blind efforts to reduce “democratic deficit” may in fact aggravate the violation of Nobodies’ rights.
The Legal Environment of Salmond's Time
Authors: Finn Jeremy
Published: September 2019

This paper examines through multiple lenses the world of the lawyer in early 20th century New Zealand. It considers, and places in their social and political context, the major issues with which Parliament and the courts were dealing, notably issues to do with alienation of Māori land and attempts to prohibit the liquor trade,  but also looking at law reform by private members' Bills. The reported decisions of the courts are analysed to consider the areas of frequent litigation, particularly land law (including Māori land cases), administrative and public law cases thrown up by the prohibition question and the very large volume of torts cases. It then examines the position of the judiciary and the courts, paying particular attention to agitation by the profession for increased judicial salaries and to the debates about the role of the Privy Council following its judgment in Wallis's case. It concludes with a discussion of the organisation and membership of the legal profession, the state of legal education and the development of a body of locally-generated legal literature.
"Salmond's Bench": The New Zealand Supreme Court Judiciary 1920-1924
Authors: Morris Grant
Published: September 2019

John Salmond dominated the New Zealand legal environment during the early twentieth century. Salmond performed many roles in the New Zealand legal system. This article focuses on his final legal role, as a Supreme Court judge, and looks at the nature of the Supreme Court Bench from 1920 to 1924. Some of New Zealand's greatest legal names sat with Salmond during this time. Twentieth century New Zealand legal history is a relatively unexplored area and requires more attention from historians. This article provides the basis for possible future work on the Supreme Court Bench during the early 1920s. In discussing the nature of "Salmond's Bench" the backgrounds of the different Supreme Court justices are explored. Following this, selected cases are analysed revealing distinctive factors relating to how this group of judges worked together and the nature of their judgments. Particular attention is paid to the divisions on the Bench regarding the crucial social issue of divorce. Viewing the decisions made by Salmond's Bench in the context of the political and social backgrounds of the judges and the historical background of this period provides a vital third dimension to the judgments. Salmond's distinctive approach to judicial decision-making becomes clearer when directly compared with the approaches of his judicial peers.
"Treaty Principles": Constitutional Relations Inside a Conservative Jurisprudence
Authors: McHugh PG
Published: September 2019

This article looks at the impact and afterlife of the groundbreaking Maori Council judgments handed down in the late 1980s by the Court of Appeal presided by the late Sir Robin Cooke (as he then was). This article refutes any notion of constitutional relations with Māori being founded on race despite unilateral (and long discarded) legal design tending towards that characterisation. The true pattern has been iwi-based and it has arisen from the continuity of whakapapa in the organization of Maori political life and relations with the state notwithstanding meddlesome but ultimately ineffectual legislative attempts to dilute tribalism. Over the past twenty plus years, the Treaty claims processes initiated in 1985 have accentuated and revitalised that tribalism. Far from licensing judicial interventionism "Treaty principles" are part of an embedded and conservative jurisprudence of Māori affairs. Their elimination from legislation would amputate a major segment of that jurisprudence. The courts, whose profile in this broad field (Treaty claims processes most notably) is mostly a resiling one, would respond by generating their own version. The legacy of Sir Robin Cooke’s court is deep-rooted and thoroughly integrated into the New Zealand legal system.
Administrative Review of the Treaty of Waitangi Settlement Process
Authors: Andrew Jessica
Published: September 2019

This paper looks at administrative review of the negotiation and settlement process for Treaty of Waitangi historical claims. The foundation is an analysis of the current treatment of these claims within the political arena, the Waitangi Tribunal and the courts. This includes a detailed analysis of the effectiveness of political and Waitangi Tribunal responses, and a hard look at the validity of the courts' continued stance that Treaty settlement cases are non-justiciable.Due to the non-binding nature of its recommendations, the effectiveness of the Waitangi Tribunal depends largely on the existence of political buy-in from the Executive and political branches of government. Analysis of the evidence illustrates that this buy-in is lacking. Despite the intensity of Waitangi Tribunal scrutiny in this area, very few meaningful outcomes are being achieved. Finally, the discussion of the courts' response to Treaty settlement claims looks closely at the concept of non-justiciability and the courts' continued application of broad precedents without meaningful analysis. This paper argues that a thorough understanding of the cases brought before the courts illuminates differences between those precedents being applied and the cases now being heard. Declaring a case non-justiciable has serious consequences and should not be done lightly.
New Zealand's Accident Compensation Scheme and Man-Made Disease
Authors: Hook Maria
Published: September 2019

This paper proposes that cover provided for "personal injury" within the current Injury Prevention, Rehabilitation, and Compensation Act 2001 should be extended to include man-made disease. The concept of man-made disease is used to distinguish between naturally occurring diseases and diseases that are predominantly caused by human activities.  An analysis of the existing principles within the accident compensation scheme reveals that such an amendment is supported by three principles in particular: the replacement of the right to sue for personal injury, community causal responsibility and prevention. It is argued that as well as introducing long-needed consistency into the scheme, cover for man-made disease would remedy some of the problems regarding compensation for work-related diseases.

The author discusses the relationship between common law and statute, a topic in which Lord Cooke had a real interest and on which he and the author discussed in person.
Felix Cohen and the Spanish Moment in Federal Indian Law: A Study in Law, Politics and Historiography
Authors: Boast Richard P
Published: September 2019

One of the best-known discussions of the historical foundations of native title law is Felix Cohen's famous paper on the Spanish Origins of Federal Indian Law, published originally in 1942 and since then reprinted many times.This article cites Cohen's paper in its political and historiographical context, paying particular attention to Cohen's role as one of the architects of the Indian Reorganisation Act of 1934, and considering also shifts in American historiography and legal writing relating to the Spanish legacy as exemplified by legal historians such as James Brown Scott and historians such as H E Bolton. This article also considers fully Cohen's analysis of the precise ways in which Spanish law penetrated the legal framework of Federal Indian Law in the United States and concludes that, as a historical discussion, Cohen's work is in need of substantial revision. In particular Cohen's arguments that Spanish law influenced federal Indian law via international law and by means of judicial consideration of old Spanish land claims seem difficult to sustain.
Civil Jurisdiction, Settler Politics, and the Colonial Constitution, circa 1840-58
Authors: Ward Damen
Published: September 2019

In early colonial politics, decisions about lower court jurisdiction often reflected competing ideas about the relationship between different parts and functions of government. In particular, court structure and jurisdiction could be seen as having important implications for the role and power of the governor. Appreciating the importance of jurisdiction as a way of defining, and arguing about, the distribution and exercise of political and legal authority in the colonial constitution allows connections to be drawn between different elements of settler politics in the 1840s and 1850s. The closing of the Court of Requests by Governor Grey in 1848, and the decisions of the Supreme Court judges in subsequent litigation, provide examples of this. Debate over the role of the governor in emerging systems of representative and responsible government after 1852 contributed to lower court jurisdiction remaining politically significant, particularly in relation to Māori.  This is shown by considering parliamentary debates about the Stafford ministry's 1858 proposals for resident magistrates' jurisdiction over "native districts". The politics of jurisdiction were part of wider contests about the establishment and consolidation of particular political and institutional relationships within the colonial constitution. This multi-faceted construction of government authority suggests a need to reconsider elements of Pākehā colonial politics and law.

Observations sur la situation politique de la Polynesie Francaise au travers de quelques principies de bonne Gouvernance enonces par le PNUD 1997 et le Pacific Plan 2006-15
Authors: Sage Yves-Louis
Published: September 2019

Since 2004, the political situation in French Polynesia has been marked by chronic instability. Waves of electoral reform initiatives undertaken by the government in order to improve political life have not been successful. This is not surprising since these reforms have been adopted without appropriate consultations with the population and often against the wishes of the local assembly. As a result, these reforms have in fact accentuated the problems they were supposed to resolve. This situation, criticised by a large majority of Polynesian voters, is the result of the violation by the principal political actors in French Polynesia of the principles of good governance developed by the United Nations Development Programme in 1997 and by the Pacific Islands Forum in the Pacific Plan 2006-15. Yet, these are not unsolvable problems should the political actors show the will to tackle them efficiently.
L'Europa Cinquanta Anni Dopo
Authors: Patrono Mario
Published: September 2019

In this article, the author offers a few reflections on the long journey of the European continent from an economic community built against the backdrop of war towards a legal construct expanding both geographically towards Eastern Europe and substantively in search of greater legal and political integration. From its humble beginnings in the 1950s to its latest round of enlargement in 2007, the article surveys the principal legal instruments and political initiatives developed by the European Community and addresses its achievements as well as its failures. The legal and political struggles related to the attempts of European Union leaders to favour greater integration are also discussed. The article then assesses the impact of the past 50 years on the European citizens before examining the role of the European Union on the global stage. In this age of globalisation and technological advances, the challenges facing the European Union remain significant; they must be tackled decisively.
To be, or not to be: Enhanced Cooperation in International Divorce Law within the European Union
Authors: Boele-Woelki Katharina
Published: September 2019

Professor Tony Angelo has throughout his career devoted much of his energy to the conflict of laws and in particular to problems created by different substantive rules relating to family law. It is therefore appropriate in this article that Professor Boele-Woelki reviews the recent European attempts to integrate the European Union's approach to international divorce. Professor Boele-Woelki reviews the process that led to the formulation of the proposals known as 'Rome III' and why those proposals ultimately failed. She argues, in part, that the failure of the international divorce process, at least at the moment, reflects significant disagreement amongst members as to the substantive content of their own laws. She expresses some concern that the ultimate solution to that substantive disagreement may be the further employment of the concept "enhanced cooperation" amongst those members who can reach agreement on substantive content of divorce law, but which leaves others behind. The professor's concern is that while that such an enhanced cooperation regime may enable an agreement to be concluded, it has significant impact on the universality that the European Community and the European Union have previously sought to impose upon members, and creates further risk of a "two-speed" European Union.

Authors: Halomoan Nico , Nugroho Astri R
Published: September 2019

ABSTRACTThe fixation of carbon dioxide (CO2) by microalgae is seen as an economical and environmentally friendly way to reduce CO2 emissions. Variations in the CO2 mass flow rate were carried out to asses the effectiveness of CO2 biofixation on the production of microalgae through microalgae Scenedesmus obliquus activity in bubble column photobioreacters through the mass transfer process. The amount of microalgae production is one of the common parameters that are often used to assess the performance of photobioreactors in addition to CO2 removal efficiency. The microalgae growth rate was measured by measuring the concentration of biomass and cell density, concentration of CO2 input, CO2 output, dissolved CO2 with acidity alkalinity test. The flow rate used is 2 L/ min, 5 L/min and 8 L/min, concentrations of CO2 (v/v) flowed into the photobioreactor f 2%, 5% and 10%. The results showed that variation of flow rate influenced growth rate and cell density of microalgae Scenedesmus obliquus.Keywords: carbon dioxide, flow rate, photobioreactor, Scenedesmus obliquusABSTRAKFiksasi karbondioksida (CO2) oleh mikroalga dipandang sebagai cara yang ekonomis dan ramah lingkungan untuk mengurangi emisi CO2.

Published: September 2019

ABSTRAKPerubahan bentuk dan dimensi sudu akan menurunkan kinerja turbin angin. Perubahan bentuk dan dimensi sudu sangat dipengaruhi oleh kekakuan dan kekuatan sudu turbin tersebut. Pada kasus di lapangan, ditemui bahwa sudu turbin angin sumbu vertikal yang dibuat dengan bahan komposit serat karbon ternyata tidak memiliki kekakuan yang baik jika hanya dibuat dengan satu lapis (layer) serat karbon. Untuk mengatasi masalah kekakuan ini, maka dilakukan penambahan tulang penguat (stiffener rib) dari bahan yang sama pada sudu turbin angin. Pengujian yang telah dilakukan menunjukan bahwa penambahan tulang penguat pada sudu turbin angin sumbu vertikal telah menambah kekakuan sudu secara signifikan yang cenderung mengikuti grafik eksponensial. Kekakuan (K) sudu dengan tinggi tulang 6 mm adalah 0,0258 kg/mm. Kekakuan sudu dengan tinggi tulang 9 mm adalah 0,0740 kg/mm. Kekakuan sudu dengan tinggi tulang 12 mm adalah 0,2250 kg/mm. Di sisi lain, kekuatan lentur sudu turbin juga meningkat. Dengan penambahan tulang 6mm, kekuatan lentur maksimum (􀀀max) mencapai 4,008 kg/mm2, dengan penambahan tulang 9 mm kekuatan lentur mencapai 4,145 kg/mm2, dengan penambahan tulang 12 mm kekuatan lentur mencapai 4,544 kg/mm2.Kata kunci: sudu turbin angin sumbu vertikal, inersia penampang, kekakuan, kekuatan lentur.ABSTRACTChanges in shape and dimension of the blade will decrease the wind turbine performance. These change are strongly influenced by the stiffness and strength of turbine blade. It was found that vertical axis wind turbine blades which is made with carbon fiber composite did not have good stiffness if it was made with only one layer of carbon fiber. To overcome this stiffness problem, stiffener rib with the same material was applied on wind turbine blade. The test that has been done shows that the addition of the stifferner rib to the vertical axis wind turbine blade has significantly increased the stiffness that tends to follow the exponential graphic. The stiffness (K) of the blade with 6 mm rib height is 0.0258 kg/mm. The blade stiffness with 9 mm rib height is 0.0740 kg/mm. The blade stiffness with 12 mm rib height is 0.2250 kg/mm. On the other hand, the bending strength of the turbine blade is also increased. With the addition of 6mm rib, the maximum flexurall strength (smax) reaches 4,008 kg/mm2. With the addition of 9 mm rib, the strength reaches 4,145 kg/mm2. With the addition of 12 mm rib, the strength reaches 4,544 kg/mm2.Keywords: vertical axis wind turbine, inertia, stiffness, flexurall strength.

Для врахування можливих змін ситуацій обстановки, що призводять до необхідності суттєвого зростання обсягу інформації для відображення, доцільно використовувати комбіновану структуру інформаційної моделі. Наведено співвідношення, які надають можливість оцінити характеристики структури інформаційних моделей на етапі їх ергономічного проектування і визначити кількість інформаційних елементів в одній програмі відображення з урахуванням мінімізації часу пошуку заданих елементів. Наведено можливі варіанти спільного використання засобів відображення інформації як індивідуального так і групового та колективного користування. Запропоновано структуру процесу та послідовність і зміст операцій при розробці вимог до форми інформаційних елементів. Наводяться дослідження ефективності використання різних форм подання інформаційних елементів. В підсумку наводяться структура, зміст та послідовність етапів методу проектування і синтезу інформаційних моделей для інформаційної підтримки прийняття рішень з оцінки обстановки, який на відміну від існуючих враховує етапи діяльності та специфіку задач, що вирішуються операторами в автоматизованих системах управління повітряним рухом.

У статті розглянуто метод розрахунку максимальних інтенсивностей інформаційних потоків у гіперконвергентній системі. Мета статті – розробка методу розрахунку максимальних інтенсивностей інформаційних потоків при централізованому управлінні, котрий повинен враховувати особливості централізованого управління і відсутність гетерогенності програмних і апаратних засобів. Результати дослідження. Проведений попередній аналіз причин затримки пакетів в гіперконвергентній системі показав, що для її розрахунку достатньо мати значення таких параметрів: інтенсивність інформаційних потоків; довжина маршрутів; час комутації пакета; пропускна здатність каналів зв'язку; довжина пакета. Розроблений метод базується на двохетапному підході до вирішення завдання. На першому кроці здійснюється обчислення прогнозованої середньої затримки пакета. На другому кроці виконується обчислення значень інтенсивностей потоків даних, що циркулюють в системі, та запускається процес ітеративного розподілу для отримання значень максимально можливих інтенсивностей інформаційних потоків. Слід зазначити, що запропонований метод орієнтований на централізоване управління наявними ресурсами. Висновок. Запропонований метод орієнтований на централізоване управління наявними ресурсами та дозволяє підвищити ефективність експлуатації гіперконвергентних систем.

Program Rujuk Balik (PRB) merupakan program yang berpotensi memberi banyak manfaat bagi peserta BPJS Kesehatan yang menderita penyakit kronis. Kajian ini bertujuan mengkaji proses pelaksanaan PRB Badan Penyelenggara Jaminan Sosial (BPJS) Kesehatan. Data diperoleh dengan panduan wawancara terstruktur yang ditanyakan kepada manajemen BPJS Kesehatan, penanggung jawab PRB di Puskesmas dan Rumah Sakit serta penanggung jawab apotek yang bekerjasama dengan BPJS Kesehatan. Identifikasi kendala proses pelaksanaan PRB menggunakan pendekatan sistem, sedangkan pendekatan Root Cause Analysis digunakan untuk mencari penyebab yang mendasarinya. Hasil penelitian menengarai masalah utama pelaksanaan PRB adalah 1) ketersediaan obat PRB di Puskesmas terbatas, 2) penumpukan pasien di Fasilitas Kesehatan Rujukan Tingkat Lanjut (FKRTL) sehingga waktu tunggu memanjang, 3) notifikasi status pasien â€œpotensi PRBâ€ pada program VCLAIM di FKRTL cenderung diabaikan, 4) rendahnya kepatuhan tenaga medis di FKRTL dalam melengkapi form rujuk balik, dan 5) sosialisasi mekanisme PRB kepada masyarakat masih kurang. Penyebab dasar timbulnya masalah ini adalah tidak adanya metode evaluasi dan sumber daya manusia dari BPJS yang secara khusus melakukan proses pengawasan dan evaluasi berkala. Direkomendasikan kepada BPJS agar menugaskan staf khusus untuk memantau PRB secara berkesinambungan dan menyeluruh, serta bersama kolegium profesional kedokteran untuk segera menyusun standar ketentuan pasien stabil setiap penyakit yang termasuk dalam PRB.

Stunting adalah suatu keadaan dimana indeks tinggi badan menurut umur di bawah -2 SD berdasarkan dari standar WHO. Keadaan ini adalah manifestasi jangka panjang dari faktor konsumsi diet berkualitas yang rendah, penyakit infeksi yang terjadi berulang dan factor lingkungan. Tujuan penelitian ini adalah untuk mengetahui faktor-faktor yang berhubungan dengan kejadian stunting. Hasil penelitian menunjukkan bahwa stunting dipengaruhi oleh tingkat asupan energi, riwayat durasi penyakit infeksi, berat badan lahir, tingkat pendidikan ibu dan tingkat pendapatan keluarga. Metode penelitian ini adalah studi literature dengani berbagai referensi, seperti artikel atau jurnal penelitian, review jurnal, annual  report, buku dan data-data yang mendukung dengan kejadian stunting yang diterbitkan dari tahun 2009 - 2019. Pencarian dilakukan menggunakan mesin pencari google di internet dengan kata kunci yang terkait, seperti: stunting, faktor resiko, penyakit infeksi, imunisas dan vaksin. Pencarian database dilakukan di PubMed, PLoS, Reaserchgate, WHO dan Depkes RI. Kesimpulan dari penelitian ini adalah memberi saran kepada pemerintah, instansi kesehatan, dan pihak terkait untuk berkolaborasi menerapkan kebijakan untuk mengurangi risiko stunting. Selain itu, masyarakat disarankan mendapatkan pendidikan yang berkualitas, memberikan asupan nutrisi yang seimbang serta meningkatkan derajat kesehatan anak dan pengembangan EST (Eco Support Theory) dalam rangka mengurangi stunting di Indonesia.

L’effet-tuteur dans l’accompagnement des élèves présentant un trouble neurodéveloppemental
Authors: KALUBI Jean-Claude , ANGRAND Rosly
Published: September 2019

Plusieurs travaux portant sur la réussite scolaire ont mis l’accent sur les facteurs d’impact et les gestes favorisant une mobilisation adéquate des approches d’enseignement. Les communautés éducatives à travers le monde exposent d’innombrables ressources en vue d’ajuster les pratiques enseignantes sur le terrain. Elles aident aussi à trouver des moyens pour rendre visibles les apprentissages des élèves. Leurs préoccupations convergent aussi autour des rôles déterminants joués par les enseignants. Ces derniers assurent aussi la mission de connecter les systèmes éducatifs aux technologies nouvelles. Le processus de médiation symbolique relié aux fonctions de tuteurs produit des effets transformateurs relevant de quelques facteurs de protection. Le contexte d’utilisation de la technologie est variable, à l’école, à la maison comme dans la communauté. Une recherche exploratoire a été menée concernant l’encadrement des élèves présentant un trouble neurodéveloppemental. Associant la recension des travaux scientifiques à des entrevues semi-dirigées (élève, parent, enseignant), ce texte met en évidence les atouts de l’effet-tuteur, considéré comme une force dans l’accompagnement des élèves.
