Published: February 2017

Abstract
The objective of this study is to investigate the nature of the social function principles of land rights within the theoretical and juridical perspective and its implementation in Indonesia. This research used the sociological or empirical research method to view the effectiveness of law in society. The result of research shows that the nature of social function principles of land rights theoretically is an acknowledgement of individual, social, and public interests in lands. The juridical basis of the social function principles of land rights refered to Article 6 of Law Number 5 of 1960 regarding Basic Regulations for Agrarian
welfare. The social function principles are materialized in various law norms that are land reform, land consolidation, land redistribution, abandoned land controlling, and land provision for public interest. The government through the National Land Agency controls land affairs as to protect its citizens’ land rights. The implementation of the social function principles of land rights is also done through the community empowerment program, namely: Pokmasdartibnah (community groups which are aware of land affairs) established by the National Land Agency and participation through Consortium Agrarian Reform, which establishes Damara (Advanced Land Reform) villages.

Keywords: Social function principles, theory, implementation

Beethoven and Byzantium: How does Film Music Help to Tell a Story?
Authors: Sanders Barry 
Published: February 2017

What is the relationship that exists between film characters and film music and does this relationship affect the audience’s understanding of film narrative? In order to answer these questions, this article explores how the terms ‘diegetic’ and ‘non-diegetic’ have been defined, and summarises the alternative interpretations which have been proposed by musicologists to date. In addition, it considers a psychological survey conducted in 2013 by Matthew Spackman, Elizabeth Wakefield and Siu-Lan Tan, which tests how narrative is shaped by film music. Finally, this article focuses on the use of the Adagio (movement II), from Beethoven's piano sonata Op. 2 No. 3, in the film Byzantium to discuss how both its diegetic and its non-diegetic presentation of this sonata helps director Neil Jordan to articulate the complexity of the narrative that is unveiled as the film progresses.
Media freedom with integrity and ethics
Authors: Nandan Satendra 
Published: February 2017

In Fiji, too much damage had been done by tendentious propaganda by a few that had frayed the fabric of the Fijian society at so many levels of social harmony and political growth of a young democratic nation. And once a nation (and a person) suffers heart-attacks, it must take care of its daily diet and exercise both restraint and responsibility. This is never more important than during an election. This commentary argues that freedom of the press, academic freedom and parliamentary privilege, are advanced and strengthened by those who practise these with professional ethics and personal integrity and conscientiously deepen public trust, individually and collectively. When the institutions are diminished, everybody is diminished.
Media, politics and the threats to journalists in Pakistan
Authors: Aslam Rukhsana 
Published: February 2017

This article examines how the fundamental right of freedom of expression for news media in Pakistan continues to be threatened both by the government and conflicting parties, an issue that is compounded by the threat to the journalists’ safety and survival. Giving examples of three Pakistani journalists who lost their lives after their investigations during the America’s so called ‘War on Terror’, the article gives an account of the nature of the dangers and threats that are faced by the journalists in Pakistan who report on armed political conflicts. Drawing on the experiences of five other journalists, who were interviewed during research visits to Pakistan in 2012 and 2014, the author also reflects on the role of journalists in the light of the social responsibility theory and explores some of the factors that contribute towards making conflict reporting a dangerous business in Pakistan.Pictured: Figure 1: The Press in Stress report in 2012.

Frontline: ‘Cloud forest’, court battles and competing narratives: A Pacific research journalism case study
Authors: Davies Kayt 
Published: February 2017

This Frontline article documents and analyses the process of creating a piece of journalism about an Indigenous-run legal bid in the Solomon Islands to challenge potentially corrupt government logging approvals. It also documents the responses of 12 editors to whom the piece was presented to, including the reasons, in terms of standard newsworthiness criterion, that some of them gave for not running the article. This process illustrates how the criteria exclude coverage of some international issues. According to lawyers working on it, this case could set important legal precedents that change the way companies deal with both the government and traditional land owners in the Solomon Islands. Spreading its relevance to other places, the story, when told at length, differs from and therefore challenges stereotypical narratives about PacificIslanders. In doing so, it contributes to a process called ‘social bridging’ described by Ward (2010) as being an aim of ethical journalistic practice. The writing and publication process are analysed with reference to Foucault’s (1972) model of discourse and enunciative modalities.Pictured: Figure 1: ‘Cloud forest’: Mt Rano from the crater rim near Mt Veve on Kolombangara Island.

What role does, could or should theology play in current discussions about our political realities? Is there a place for theological worldviews in the public conversation about policy making? Should theology critically unmask the underlying theological and metaphysical sources of contemporary politics?
The contributors to this volume reflect on new questions in public and political theology, inspired by the theology of Edward Schillebeeckx. They discuss a variety of theological traditions and theories that could offer substantial contributions to current political challenges, and debate whether theology should contribute to the liberation of communities of poor and suffering people.
An activity index for geomagnetic paleosecular variation, excursions, and reversals
Authors: Panovska S. , Constable C. G. 
Published: February 2017

AbstractMagnetic indices provide quantitative measures of space weather phenomena that are widely used by researchers in geomagnetism. We introduce an index focused on the internally generated field that can be used to evaluate long term variations or climatology of modern and paleomagnetic secular variation, including geomagnetic excursions, polarity reversals, and changes in reversal rate. The paleosecular variation index, Pi, represents instantaneous or average deviation from a geocentric axial dipole field using normalized ratios of virtual geomagnetic pole colatitude and virtual dipole moment. The activity level of the index,
, provides a measure of field stability through the temporal standard deviation of Pi. Pi can be calculated on a global grid from geomagnetic field models to reveal large scale geographic variations in field structure. It can be determined for individual time series, or averaged at local, regional, and global scales to detect long term changes in geomagnetic activity, identify excursions, and transitional field behavior. For recent field models, Pi ranges from less than 0.05 to 0.30. Conventional definitions for geomagnetic excursions are characterized by Pi exceeding 0.5. Strong field intensities are associated with low Pi unless they are accompanied by large deviations from axial dipole field directions.
provides a measure of geomagnetic stability that is modulated by the level of PSV or frequency of excursional activity and reversal rate. We demonstrate uses of Pi for paleomagnetic observations and field models and show how it could be used to assess whether numerical simulations of the geodynamo exhibit Earth‐like properties.
Modification of dry‐spun Suplon polyimide fibers by mixed‐acid oxidation and their effects on the properties of polypropylene‐resin‐based composites

Published: February 2017

ABSTRACTIn this study, the effects of mixed‐acid oxidation on the contents of surface elements, morphology, fiber fineness, mechanical properties, mass change rate, chemical structure, and microaggregate structure of dry‐spun Suplon polyimide (PI) fibers were systematically investigated with wet chemical treatment with HNO3/H2SO4. Experiments investigating both the improvement in the O/C ratio of the fiber surface elements and the changes in other performance features were conducted through the functional modification of the fibers. Meanwhile, the causes of specific changes in the mechanical properties of the oxidized PI‐fiber‐reinforced polypropylene‐resin‐based composites were studied and are discussed. The results of this study demonstrate that the treatment of the fibers with HNO3/H2SO4 mixed‐acid oxidation resulted in significant changes in the properties of the fibers; these changes included an uneven surface, increased specific surface area and surface roughness, a locally etched surface, increased surface energy and O/C ratio, an enhanced wettability, an increased fiber fineness, reduced mechanical properties, and a mass gain in the fibers. Although the chemical structures of the fibers treated by oxidized HNO3/H2SO4 were not significantly changed compared to those of the untreated fibers, the microscopic aggregation of the treated fibers changed to some degree, and the ratio of the amorphous regions significantly increased. Taken together, the functional modification of the PI fiber surface was achieved efficiently through the use of a suitable HNO3/H2SO4 oxidation process and with other performance features of the fibers taken into account. This was favorable for the enhancement of the interfacial properties of the polypropylene fibers and the matrix resins, and thus, the modification improved the mechanical properties of the composites. © 2017 Wiley Periodicals, Inc.

School composition, school culture and socioeconomic inequalities in young people's health: Multi‐level analysis of the Health Behaviour in School‐aged Children (HBSC) survey in Wales

Health inequalities emerge during childhood and youth, before widening in adulthood. Theorising, testing and interrupting the mechanisms through which inequalities are perpetuated and sustained is vital. Schools are viewed as settings through which inequality in young people's health may be addressed, but few studies examine the social processes via which institutional structures reproduce or mitigate health inequalities. Informed by Markham and Aveyard's theory of human functioning and school organisation, including their concept of institutional boundaries, critical theories of marketisation and the concept of micro‐political practices within schools, this paper presents analysis of student survey data (N = 9055) from 82 secondary schools in Wales. It examines the role of socioeconomic composition, social relationships at school and institutional priorities in mitigating or perpetuating health inequality. It finds that affluent schools were most unequal in terms of student health behaviours and subjective wellbeing. In relation to health behaviours, students from affluent families accrue a disproportionate benefit. For wellbeing, students from poorer families reported lower subjective wellbeing where attending more affluent schools. Student–staff relationships appear to be a key mechanism underpinning these effects: poor relationships with staff were predicted by a pupil's position within schools’ socioeconomic hierarchy and associated with worse health outcomes. That is, students from the poorest families reported better relationships with teachers where attending less affluent schools. Universal approaches engaging with these social processes are needed to reduce health inequalities.

AbstractZinc is important for cell physiology and alteration of its levels during development can modulate a series of biological events. The aim of this study was to investigate whether dietary zinc deficiency or supplementation during morphogenesis and early postnatal development could interfere in prostate maturation. Pregnant rats were exposed to a standard diet (NZ:35 mg Zn/kg chow), low‐zinc diet (LZ:3 mg of Zn/kg chow) and zinc‐supplemented diet (HZ:180 mg/Kg chow) from gestational day 10 (GD10) through postnatal day 21 (PND21). After weaning, male offspring were divided into three groups that were submitted to the same food conditions as their mothers until PND53. The animals were euthanized at PND53 and PND115. The ventral prostate was removed, weighed and its fragments were subjected to histological, western blot and zymography analysis. PND53: body and prostate weight were lower in LZ compared to NZ; the epithelial compartment was reduced while the stromal compartment was increased in LZ compared to NZ; there was an increase in the amount of collagen and reduction in AR and SIRT1 expression in LZ compared to NZ. PND115: body weight was lower in LZ compared to NZ and prostate weight was similar among the groups; peripheral physiological hyperplasia was observed, as well as an increased epithelial proliferation index and reduced PAR4 expression in LZ and HZ compared to NZ. Zinc deficiency during prostate morphogenesis and differentiation is potentially harmful to its morphology, however, by restoring the standard dietary environment, the gland responds to the new microenvironment independent of the previous dietary condition.
