title: Oblique and rippled heliosphere structures from the Interstellar Boundary Explorer.

authors: Zirnstein, Eric J.

subjects: Astrophysical plasmas

abstract: Past analysis has shown that the heliosphere structure can be deduced from correlations between long-scale solar wind pressure evolution and energetic neutral atom emissions. However, this required spatial and temporal averaging that smoothed out small or dynamic features of the heliosphere. In late 2014, the solar wind dynamic pressure increased by roughly 50% over a period of 6 months, causing a time and directional-dependent rise in around 2-6 keV energetic neutral atom fluxes from the heliosphere observed by the Interstellar Boundary Explorer. Here, we use the 2014 pressure enhancement to provide a simultaneous derivation of the three-dimensional heliospheric termination shock (HTS) and heliopause (HP) distances at high resolution from Interstellar Boundary Explorer measurements. The analysis reveals rippled HTS and HP surfaces that are oblique with respect to the local interstellar medium upwind direction, with significant asymmetries in the heliosphere structure compared to steady-state heliosphere models. We estimate that the heliosphere boundaries contain roughly ten astronomical unit-sized spatial variations, with slightly larger variations on the HTS surface than the HP and a large-scale, southwards-directed obliquity of the surfaces in the meridional plane. Comparisons of the derived HTS and HP distances with Voyager observations indicate substantial differences in the heliosphere boundaries in the northern versus southern hemispheres and their motion over time.

title: Competing discourses of conservation and sustainability in state-sponsored tourism development: A critical analysis of the Lake Toba case in Indonesia

authors: Mujib, Taufiqul

subjects: Critical discourse analysis

abstract: The Indonesian government has an ambitious project to develop the tourism sector and to increase the state's foreign exchange: the National Tourism Strategic Area (KSPN).
The project has been prioritised in ten regions, one of which is Lake Toba in the province of North Sumatera. In promoting this project, the government has claimed that the Lake Toba tourism development programme will conserve nature and contribute positively to the economic development of the local community of North Sumatera province. The project has, however, faced resistance from the locals, and in particular the community of Sigapiton village in the Tobasa regency, because the land claimed by the Lake Toba Tourism Authority or Badan Otorita Pariwisata Danau Toba (BOPDT) is customary land belonging to local clans. In examining this conflict, this study investigates how the discourses of conservation and sustainability have been deployed by the government and challenged by the local community in the struggle for control over natural resources in the Lake Toba region.

This study uses the critical discourse analysis (CDA) approach to uncover and analyse the discourses used by the government to control natural resources in the context of
ecotourism in Lake Toba. Specifically, the study adopts Fairclough's (2012) notion of three domains that must be analysed, namely text (speech, writing, visual images, or a combination of all three); discursive practices that include the production and consumption of texts; and
social practices.

The analysis demonstrates that the government not only uses the discourses of sustainability and conservation to govern the natural resources at Lake Toba but also
optimises policy setting and development incentives to implement an institutional arrangement through the establishment of the forestry estate as a process of
"territorialisation" of land claimed as state forest. The arrangement requires the existence of binding agreements and regulations to determine who has the right to and control over natural resources, as well as formulate their conditions to access it. 

Furthermore, the government uses two issues to promote the Lake Toba tourism project, namely environment (nature conservation) and social-economic welfare. The
government argues that the project aims to conserve nature and improve the local economy.The government also claims that the project can stimulate local awareness of the need for nature conservation. Civil society has countered government arguments by advancing the concept of “green grabbing”. They believe that in fact Lake Toba represents a new model of community exclusion, where communities are excluded from their traditional lands and living space on the grounds of ecotourism.

Ko tā te tuhinga nei he whakakite i ngā āwangawanga o te kaituhi mō te maha o te hunga taiohi kua tipu mai i raro i te ātaarangi o te Kōhanga Reo, o te Kura Kaupapa Māori, o te wharekura hoki, kua noho ko te reo Māori hei reo tuatahi, engari mō te aronui ki te reo me tōna katoa kore kore rawa atu. Kei te kōrerohia ōna hītori me tōna whakapapa. I ahu mai tō tāua reo i hea? I pēhea tō tāua reo i ngā wā o mua? I pēhea tō tāua reo i te taetanga mai o tauiwi i te takiwā o te 1800? I ahatia tō tāua reo e tauiwi i tērā rautau i kīa ake he reo koretake noa te reo Māori? Nā wai tō tāua reo i ruke ki rāhaki i ngā tau 1900? Ka mutu, nā wai tō tāua reo i whakahoki mai ki te kōpū o tēnei whakatipuranga? Nā ēnei tūmomo urupounamu au i karanga ki te ihi o tōku whare kōrero. 
Ko te ngako o ngā kōrero o roto i te tuhinga nei he whakatewhatewha, he matapaki i te kūare o te hunga taiohi ki te whakapapa, ki te hītori o te reo Māori. Koia ko ōna piki me ōna heke, ngā whakapātaritari i ngana ki te whakapoko i te ahi o te reo Māori i te tata whāngaromanga ōna. Ko te nuinga o ngā kōrero he mea rangahau mai i ngā pukapuka me te whakatakoto i ngā kitenga hei pānuitanga mā te hunga e tāpara ana ki ngā kai o roto. Me whakanui ka tika ngā pēhitanga o te hunga i takatakahi i te ara papatoiake hei whaitanga mā tātau ka tahi, ka rua me kōkuhu ēnei tūmomo mātauranga ki ngā marau whakaako tamariki me kore noa e tahuri mai te hunga taiohi ki tōna reo me tōna katoa. E ora ai te whakapapa o te reo me ōna hītori me whakakōpā e tātau  tōna whakapapa, me ōna kōrero ki ngā tamariki kōhanga mai, kura kaupapa mai, wharekura mai, ā huri atu ki ngā pia whare wānanga hoki. Mā te whakaako i te hītori ki a ngāi taiohi ākene pea ka tipu te kauanuanu ki tōna reo. Kia kekeno atu au ki tōku reanga kei te kitea he momo whakahīhī kua puea ake ai ki roto tonu i a tātau. Ko te momo o tēnei whakahīhī he mea tūkino i te hunga kore reo, he mea whakaiti i ngā tāngata kua noho rehurehu ki ngā kawenga a tāua te Māori. E whakapono ana au mā te kauanuanu o tōku reanga ki tōna reo ka tipu hoki te kauanuanu ki te hunga kāore pea i rongo i ngā hua o te reo, rātau te hunga kua noho pōhara, kua noho manene nā ngā rā pōkākā o te whakapākehātanga. Atu i te whakahīhī o te ngākau kua puea hoki tētahi momo e patu nei i te kōrerotanga o tō tātau reo, arā ake ko te ngākau māngere. I te korenga o te aronui o tōku reanga ki te reo kua tipu ake ētahi, ahakoa i pakeke mai i roto i te Kōhanga Reo mō te kōrero Māori atu kia pakeke ana rātau he aha te aha. Mā te ako i ngā hītori o tō tātau reo e titi ai ki te whatu manawa te hiranga o tō tātau reo, mā tērā e kore rawa te tangata e noho hāneanea me te pōhēhē ka pai noa te reo Māori, ka mutu kāore he tino take kia kaha kōrerotia. 
Ko te tino whāinga o tēnei tuhinga he ngana ki te whakarārangi mai ko hea te huarahi e tuwhera ai ngā kuaha o te ao Māori ki te katoa e tū rangatira ai tātau. Ahakoa pakeke mai taiohi mai rānei, ahakoa matatau ki te reo tauhou ki te reo rānei ko te mea nui kia tū whakahīhī, kia tū māia te iwi Māori ki raurangi.
