Six carp and carp based culture technologies were selected to examine the sustainability of supplementary feed-based aquaculture through availability of domestic feeds compared to the total requirement in Bangladesh. The study covered seven districts of Bangladesh with a sample size of 376. It was found that farmers used a good number of feeds (more than 35) for the selected technologies but they maintained no standard doses for them. There were important differences among the prices of different feeds and other inputs used for different technologies in different parts of the country. Prices of all inputs were found to be increasing and this increase has been greater in recent years as compared to previous years. Though all the technologies were found to be profitable, the feed situation was not satisfactory. Except for rice polish, the supplies of other local feeds were unable to meet the national demand. If this situation persists and no measures are taken to secure the local feed supply, the present development of supplementary feed-based aquaculture will become dependent on imported feeds and would not be sustainable in the future. This study strongly suggests that the authorities should handle the matter with proper attention, considering its significant impact in the economy of the country.

We cannot be sure exactly what will happen, we can only estimate by using a particular method, where each method must have the formula to create a regression equation and a formula to calculate the confidence level of the estimated value. This paper conveys a method of estimating the future values, in which the formula for creating a regression equation is based on the assumption that the future value will depend on the difference of the past values divided by a weight factor which corresponding to the time span to the present, and the formula for calculating the level of confidence is to use "the Haryadi Index". The advantage of this method is to remain accurate regardless of the sample size and may ignore the past value that is considered irrelevant.

The article deals with the development of the coregency system of Augustus and Agrippa from 29 to 18 BC: from formal and actual disparity of the coregents to their formal equality with the dominance of the princeps auctoritas. Particular attention is paid to the earlier stages of this development and to the crisis of 23 BC. The coregency system created by Augustus is often regarded by modern historians as means of ensuring uninterrupted succession of power. Agrippa as his coregent often is thought to have assumed the role of the regent who temporally replaces the princeps, just as it was in formal monarchies, or that of the tutor of the future rulers. However, the Roman system of state administration did not allow such type of regency. The princeps coregent, who was his equal in formal credentials but his inferior in terms of auctoritas, in case of the princeps death had to become the next princeps as his immediate successor. It is unlikely that later he was expected to voluntarily give up his power in favour of younger heir and to vanish from the political life altogether. The inheritance system under Augustus was like a ladder with the princeps at the top, the coregent who was also the immediate successor one step below, heirs of the next degree further down. In case of death of one of them, successors shifted one step up. The coregency had one more function: geographically it allowed Augustus and Agrippa to rule jointly the empire while staying in different parts of it.В статье исследуется развитие системы соправления Августа и Агриппы с 29 по 12 гг. до н. э.: от формального и фактического неравенства соправителей до их формального равенства при преобладании auctoritas принцепса, причём особое внимание уделяется раннему этапу этого развития и кризису 23 г. до н. э. Институт соправления, созданный Августом, часто рассматривается, как средство обеспечения бесперебойного перехода власти, причем Агриппе, как соправителю, НЕРЕДКО отводится роль регента, временно замещающего принцепса или воспитателя будущих правителей. Однако римская система государственного управления не предполагала регентства. Соправитель принцепса, равный ему по формальным полномочиям, но уступавший по auctoritas, в случае его смерти должен был СТАТЬ следующим принцепсом, ближайшим его наследником. Вряд ли предполагалось, что в будущем он должен добровольно уступить власть более молодому наследнику и исчезнуть из политической жизни. Система наследования при Августе представляла собой нечто вроде лестницы, на вершине которой стоял принцепс, на следующей ступени соправитель, он же избранный преемник, ниже наследники следующей очереди в случае смерти когото из них происходило продвижение наследников по ступеням вверх. Кроме того, соправление имело и иное значение позволяло Августу и Агриппе совместно управлять империей, находясь в разных ее частях.

Mobility and transportation mean different things to people, even to those who work in various aspects of the ecosystem - from the movement of people or goods to the development of the infrastructure that enables mobility. For decades these different parts of the ecosystem have been approached as entirely independent industries, but the quickened pace of technological change has driven the need to reconsider how these distinct groups create the vibrant tapestry that is our mobility ecosystem. This book seeks to capture the varied perspectives as a collection of diverse views on the future of mobility, to provide a clearer view on the broad base of possibility and opportunity across this interconnected system.

"Amazing roster of thought leaders come together to paint a picture of a whole new mobility paradigm in the interest of safety, sustainability, and equity." -- Sven Beiker, PhD.

This paper was written in response to a request by the editors of the AP: Online Journal of Public Archaeology, Jaime Almansa Sánchez and Elena Papagiannopoulou, for Claire Smith to write on the future of public archaeology in Australia. In Australia, public archaeology focusses on high profile colonial sites such as The Rocks in Sydney (Karskens 1999) and Port Arthur in Tasmania (Steele et al. 2007; Frew 2012), tourism (e.g. Cole and Wallis 2019) or enhancing school curricula (Nichols et al. 2005; Owens and Steele 2005). However, given her decades-long relationships with Jawoyn and Ngadjuri people (Smith 1999; Smith et al. 2016; Smith et al. 2020), Claire Smith decided that a useful way of approaching this topic would be to obtain Indigenous views on the subject. Accordingly, she contacted the Aboriginal co-authors of this article and invited them to co-author the paper. The possibility to write in free form was a boon. The ‘conversation’ format we settled on was designed to facilitate the voices of individuals, to present a range of Indigenous views, to allow people to express their views frankly, and to deal with the constraints of people being located in different parts of Australia as well as occasional lock-downs due to COVID-19. We decided on five topics/questions that would be the basis of the conversation. Each Aboriginal author gave their views either by email or by phone. These views were interwoven into a ‘conversation’. The language has been edited lightly for clarity and to simulate a real-life conversation. The final text was approved by all authors.

During the UK’s membership of the EU, the EU structures have provided a degree of external oversight, ensuring that environmental obligations are fulfilled. To fill the gaps left by the removal of these structures, the different parts of the UK are currently developing their own proposals for environmental principles and governance, which are briefly outlined. The different national schemes adopt different approaches and have to fit into different legal and policy backgrounds. Although collaboration is desirable it seems unlikely to be achieved, if only because of the different timescales for turning proposals into action. Progress with the different national schemes may be disrupted by the need to meet any commitments made by the UK government in international agreements. These agreements may include environmental provisions, and the “Backstop” to the Withdrawal Agreement between the UK and the EU contains substantial commitments on environmental governance. Some firm suggestions are made for enhancing future collaboration.

This paper traces aspects of the development of a 'green' criminology. It starts with personal reflections and then describes the emergence of explicit statements of a green criminological perspective. Initially these statements were independently voiced in different parts of the world but they reflected shared concerns. These works have found unification as a 'green', 'eco-global' or 'conservation' criminology. The paper reviews the classifications available when talking about not only legally - defined crimes but also legally perpetrated harms, as well as typologies of such harms and crimes. It then looks at the integration of 'green' and 'traditional' criminological thinking before briefly exploring four dimensions of concern for today and the future.

This research paper basically discussed about the empirical gaps when identifying the relationship between student engagement and their academic achievement, which would be useful for the future researches on the topic. Secondary data collection was used. A critical Literature Review was conducted using a sample size of 22 articles. The first gap is about the sample size, where the sample is being limited to just one university/school/institute. The second gap is about the way the researchers have measured the academic achievement, where most have done using a single subject result, which would be impractical. Thirdly, lack of qualitative approaches to measure the relationship between student engagement and academic achievement is identifies as a gap. As the fourth gap, students from all the years and variety of faculties should be taken, as student engagement might vary with them. As the fifth gap, many researchers have identified that most researches have been carried out targeting one country, which might be failed to give an overall result on the relationship. The sixth gap identified was that many of the researchers have paid to the respondents in filling the survey and therefore the researchers have faced restrictions due to unavailability of sufficient financial resources. The last gap which was identified throughout the literature was that information technology nowadays has an influence on student engagement and the fact was not taken into account by most of the researches. At the latter part of the research, the recommendations to the future researchers were given.

Ze względu na plebiscytowy charakter wyborów z czerwca 1989 roku przyszłych posłów i senatorów opozycyjnego Obywatelskiego Klubu Parlamentarnego de facto wyłoniono w kwietniu tego roku, kiedy zamykano listy wyborcze Komitetu Obywatelskiego. Te swoiste prawybory miały różny przebieg w różnych częściach kraju i nie były wolne od sporów (zarówno na szczeblu regionalnym, jak i na linii „teren”–Warszawa). W wyborach nie wystartowała zresztą część czołowych działaczy opozycji, idąc za przykładem Lecha Wałęsy. Ten ostatni był jednak mocno obecny w kampanii wyborczej osób reprezentujących Komitet Obywateski, których wyróżnikiem – w zdecydowanej większości – było wspólne zdjęcie z przewodniczącym Solidarności. Niewątpliwie ta nie zawsze w pełni demokratycznie wyłoniona solidarnościowa drużyna osiągnęła w wyborach sukces, obsadzając niemal wszystkie miejsca w Sejmie i Senacie PRL, które potencjalnie mogła zdobyć. Wybrani do parlamentu przedstawiciele opozycji utworzyli w nim Obywatelski Klub Parlamentarny. Due to the referendum nature of the elections in June 1989, the future deputies and senators of the opposition Civic Parliamentary Club were actually elected in April that year, when the election lists of the Citizens’ Committee were closed. These peculiar primary elections varied in different parts of the country and were not free from disputes (both at the regional level and on the “regional” – Warsaw line). Besides, some of the leading opposition activists did not take part in the elections, following the example of Lech Wałęsa. The latter, however, was strongly present in the election campaign of people representing the Citizens’ Committee, whose distinguishing feature – in the vast majority – was a photo taken with the leader of “Solidarity”. Undoubtedly, this “Solidarity” team, not always fully democratically elected, achieved success in the elections, filling almost all the seats in the Sejm and Senate of the Polish People’s Republic, which it could potentially win. The opposition representatives elected to the parliament formed there the Civic Parliamentary Club.

<p>While exploring different topics and issues—examining everything from the importance of our Pacific genealogies, to the analysis of Hawaiian language literature, to the power of prophecies and predictions for the future, to the need to be reflexive in the creation of culture, and finally to the act of building a nation—each chapter of this thesis is connected by one shifting concept: Kahiki. Furthermore, they are joined by the idea that there is life to be found there. As an ʻōlelo noʻeau, or a Hawaiian proverb, states, “Aia ke ola i Kahiki,” “Life is in Kahiki”. This adage has served as the foundation of this research and each chapter has been written with the belief that there is life—in the form of reconstructed knowledge, new interpretations, and growing understandings—to be found in Kahiki.  Encapsulated in this one term are our ancestral memories of migration. When islanders traveled to different parts of the Pacific region, they maintained knowledge of their homelands. Although the names of these homelands differ throughout the Pacific, the concept is the same: islanders knew that their life in a particular place, a particular group of islands, was dependent on other places and peoples that although out of sight were never completely out of memory. After generations, however, the specificity of these “homelands” was blurred, and one name came to represent the genealogical connection that people shared with other places in the Pacific. What was Pulotu for some, therefore, became Hawaiki for others, and eventually became Kahiki for my ancestors in Hawaiʻi. Thus, Kahiki became a general term for all lands in the region outside of Hawaiʻi, and more importantly, became a way for Hawaiians to explain their existence to themselves. In later generations, however, particularly when people from other parts of the world came to Hawaiʻi, Kahiki became a term used to refer to all lands beyond Hawaiʻi’s shores.  This thesis, therefore, studies the life of this one concept through time: looking at it as part of our Pacific genealogies, as presented in oral traditions; examining it as a means of making nationalistic statements, and sometimes, even as a means of justifying colonialism in the nineteenth century; and then exploring contemporary articulations and engagements with Kahiki, particularly in the era following the Hawaiian renaissance, when a group of men on the Big Island of Hawaiʻi built a single-hulled canoe, brining tools, teachers, and knowledge from Kahiki to give new “life” to their people. Studying the way this one concept has shifted through time provides a means of understanding how people in each generation used one term to make sense of their experiences. Furthermore, it gives us the chance to examine our contemporary movements and to reengage with Kahiki in a way that will empower us to do and be more for our people, our region, and the world.</p>
