Abstract:
The notion of productive forces is usually grasped from a narrow perspective which reduces its content to technology and productivity. The distinction between force (Kraft) and its expression (Äußerung) plays a key role in Marx's dialectical analysis. Insofar as force is the outcome of a relation in dialectics, productive forces comprise an active element, namely labor. It is through the mediation of this active element that relations of production intervene in the process of expression of productive forces, which indicates the agency, that is the subversive subject, its empowerment and possibilities. Under capitalism, all aspects of individual and social life are reduced parameters to serve the overriding principle of profit maximization. Only the empowerment of working people can avoid such parameterization of society, which requires the abolition of the law of value as well as private property in the means of production, but is not granted by this abolition. The empowerment of workers is not an outcome of the advancement of productive forces, but is rather a significant element of the latter.

Abstract:
AbstractThis article returns to the debate about the relative importance of the productive forces and the relations of production in the feudal mode of production. It argues, using western medieval evidence, that this relation is an empirical one and varies between modes, maybe also inside modes; and that, in the specific case of feudalism, not only were the relations of production the driving force, but developments in the productive forces actually depended upon them.

Abstract:
The article summarizes the scientific material on the topic, substantiates the idea that the decisive condition for economic and social growth of the country is the reproduction of productive forces, the territorial features, condition and nature of which depend on the modern development of all regions of Ukraine. The categorical and meaningful characteristic of the concept of «productive forces» is understood, by which we understand the totality of human, material and other force elements, with their inherent forming effect, which are involved in the production of means, maintenance of the conditions of human existence, social progress and self-reproductive capacity of nature, and social community, but taking into account the principle of improving the environmental situation, which will require the greening of consciousness, legislation, management. The principles of allocation of productive forces are given, among them: rational and complex placement of production, balance and proportionality of distribution of production, domestic and international division of labor, limited centralism. It is proved that the process of globalization of the world economy creates the need for European integration of Ukraine, which, in turn, will contribute to radical transformations in the way of increasing the level of socio-economic development of a democratic state and the restoration of productive forces through the restoration of all factors of production.

Abstract:
This article uses Foucault’s lecture courses to illuminate his reading of Marx’s Capital in Discipline and Punish. Foucault finds in Marx’s account of cooperation a precedent for his own approach to power. In turn, Foucault helps us rethink the concepts of productive force and labour power in Marx. Foucault is shown to be particularly interested in one of Marx’s major themes in Capital, parts III–IV: the subsumption of labour under capital. In Discipline and Punish and The Punitive Society, Foucault offers a genealogy of the forms of labour power ( Arbeitskraft) and productive force ( Produktivkraft). One of his central problems is to understand how labour power is converted in productive force and how, prior to that, productive subjects who can properly bear and dispose of their labour power are formed. Foucault’s reading of Capital resonates with those currents of Marx interpretation today that seek to repoliticize the concept of productive force and to offer a materialist account of subject formation.

Abstract:
In this paper the regional organization of collective services in socialist countries is discussed. Social infrastructure is a key aspect of regional activity. Within socialist economies shortage, or unsatisfied demand, is a driving force which stimulates natural tendencies to management stabilization in which bureaucratic structures control the distribution of goods and services. There are two rival models of regional infrastructure provision: Orientation to places of production, or orientation to places of residence. Within either model a hierarchical structure is necessary. It is becoming necessary in socialist countries to appraise the administrative consequences of social goods provision as well as of productive forces. This creates major challenges to link the productive and residence orientation of administration. This, in turn, suggests a need for a more flexible rather than a uniform approach to settlement planning.

Abstract:
Le cadre général où s’inscrit cette thèse est celui de la restructuration productive qui a introduit l’innovation technologique et de nouvelles formes de gestion et de mobilisation de la force de travail dans le cadre d’un nouveau rapport de force entre capital et travail à partir de la crise structurelle des années soixante dix. Plus précisément, le sujet de la recherche est celui de la tension entre efficacité productive et contrôle hiérarchique dans le cadre d’une automatisation croissante. Pour bien saisir cette tension, nous avons étudié avec une méthodologie ethnographique, l’organisation et les stratégies de mobilisation et de contrôle de la force de travail de deux entreprises pétroliers en Bolivie. Sur la base des résultats de notre recherche, nous avons trouvé que la tendance de la division technique du travail a suivi un processus contradictoire qui illustre la tension entre les exigences de l’efficacité technique dans les automatismes, tel que l’intégration du travail et les rapports de dominations et de hiérarchie qui sont essentiels au sein de l’entreprise capitaliste. Le processus contradictoire, qui d’un coté incite à l’intégration du travail, et d’un autre coté met en œuvre des contraintes à l’intégration. Par conséquent, si on introduit une approche d’ensemble du processus et, dans un même sens, on considère non seulement, la forme mais le contenu des rapports sociaux de production ; on trouve l’aspect inégal et contradictoire d’un processus qui, à la fois, cherche l’exploitation et la subordination de la force de travail et ouvre des espaces à de nouvelles sources de productivité à partir de l’implication des ouvriers
The general context, in which this thesis is located, is the situation of the productive restructuring that has introduced innovative technology and new forms of management and mobilization of the workforce as part of a new balance of power between capital and labour from the structural crisis of seventies. Specifically, the research subject is the tension between efficiency and hierarchical control through increasing automation. To understand this tension we have studied with ethnographic methodology, organization and ways of controlling the labour force of two companies working oil in Bolivia. Based on the results of our research, we found that the trend of the technical division of labour has taken a contradictory process that illustrates the tension between the demands of technical efficiency in automation, such as the integration of work and relations of domination and hierarchy that are essential within the capitalist enterprise. The process, one side encourages the integration of work and elsewhere implements constraints to integration. Consequently, if we introduce a comprehensive approach to the process and, in the same direction, we consider not only the form but the content of social relations of production, abut and adversarial process that while looking for the exploitation and subordination of the labour force, opens spaces for new sources of productivity from the involvement of workers

Abstract:
The aim of this study is to compare the effects of the instructions based on cognitive bridging and cognitive conflict approaches and gender on 9th grade students&lsquo
conceptual understanding of force and motion, self-efficacy, and epistemological beliefs. The study was conducted with a sample of 206 students in two different schools. The instructional method (traditional, cognitive conflict, and cognitive bridging) and students&lsquo
gender were used as independent variables in a 3x2 factorial design. Within this design, three treatment groups were constructed, one was control group with no researcher intervention and the other two were used as experimental groups. In one of the experimental groups, students received cognitive bridging instruction and students in the other group received cognitive conflict instruction. Pretests and posttests were administered to assess students&lsquo
conceptual understanding of force and motion, self-efficacy, and epistemological beliefs. Multivariate Analysis of Covariance (MANCOVA) was used to explore the main effects of teaching methods and gender, and possible interactions between them. The results showed that teaching method had a significant effect on students&lsquo
conceptual understanding of force and motion in favor of experimental groups. Nevertheless, no significant difference was detected between the effects of cognitive conflict and cognitive bridging. There was no significant difference between male and female students either on the dependent variables of conceptual understandings of force and motion, self-efficacy, and epistemological beliefs. Finally, the present study couldn&lsquo
t capture any significant interaction between teaching method and gender on the combined dependent variables.

Abstract:
Although audition may appear to be the dominant sensory modality in speech production, the capacity for intelligible speech following severe hearing loss suggests that other sensory information - for example, somatosensory feedback - may also contribute to the achievement of speech targets. The aim of this thesis is to explore the role of somatosensory feedback in speech produced by healthy adults.
The first study aimed at providing a test of whether somatosensory feedback plays a role in speech production beyond the language acquisition period in early childhood. In order to achieve this goal, we designed a pattern of forces that affects jaw movements during speech production, but at the same time has no measurable acoustic effect. We found that subjects compensated for such a distortion in speech movement trajectories, even though it had no impact on the sounds. In contrast, no adaptation was observed in matched non-speech jaw movements, indicating that this was not an inevitable consequence of exposing the orofacial apparatus to this pattern of forces. This is the first demonstration that somatosensory information on its own drives the achievement of articulator positions in speech.
In study one, it was observed that subjects only adapted to the loads in the opening phase of the jaw movement. In order to elucidate this somewhat unexpected finding, we carried out experiments in which we manipulated the linguistic content of the training utterance. We found that subjects compensated for the perturbations only in portions of the movement that contained a vowel-to-vowel transition. It was suggested that the required kinematic precision during a transition between two vocal tract shapes associated with vowels is higher than during transitions between a consonant and a vowel. It also points to the speech-like nature of the observed adaptation.
The third study aimed at investigating the extent to which speech motor learning generalizes across acoustic contexts. We trained subjects to produce utterances while exposed to a velocity dependent force field. After learning, the subjects were tested with new utterances, matched on dynamics to the ones used in training. Note that even if the acoustic contents of the test and the training utterances were different, the loads had a similar effect on both speech movements. We showed that learning did not transfer to the test utterances; therefore adaptation was restricted to the specific training context. These results point to the specificity of speech motor learning.

Abstract:
The global marketplace is highly competitive and organisations who want to survive long-term, have to continuously improve, change and adapt in response to market demands. Improvements in a company's performance should focus on cost cutting, increasing productivity levels, quality and guaranteeing deliveries in order to satisfy customers. Total Productive Maintenance (TPM) is one method, which can be used to achieve these goals. TPM is an approach to equipment management that involves employees from both production and maintenance departments. Its purpose is to eliminate major production losses by introducing a program of continuous and systematic improvements to production equipment. TPM should be developed and expanded to embrace the whole organisation and all employees should be involved in the process as members of improvement teams. This thesis describes the development of TPM and the TPM implementation process. Research is focused on the implementation process of TPM. The author has had the opportunity of both monitoring and steering a company through part of its TPM implementation program and has conducted a longitudinal study. The implementation process takes several years and this thesis focuses on the initial three years of the process. This study demonstrates that driving forces, obstacles and difficulties often are dependent on the organisation, its managers and the individual employees. It also shows that the TPM implementation process has many similarities to the implementation of other improvement concepts. The analysis of these findings forms the basis for recommendations and guidance for organisations, who intend to implement TPM.

Abstract:
One key component of powertrains is gears which are used in a continuously increasing quantity with improving quality. A productive process for finishing gears is the generating gear grinding process. The process is used mainly for large-batch production of small or mid-size gears after case hardening, especially in the automotive sector. Currently, the knowledge regarding the generating grinding process is limited and research is based mostly on empirical studies. The reasons for this are complex contacting conditions as well as the undetermined interactions between various process parameters. This paper focusses on current questions about generating gear grinding such as new approaches for a simulation based process design in consideration of cutting forces as well as the changing contact conditions.

Abstract:
The aim of this study was the identification of spatial differentiation of agricultural productive potential and the assessment of effectiveness of its use in Poland. According to the EUROSTAT data in 2011 Polish agriculture comprised 8.35 % of agricultural area of the European Union and 20 % of the labour force of the EU agricultural sector. At the same time Poland’s share in the EU agricultural production was only 5.79 %. In order to evaluate the differentiation level of agricultural productive potential as well as the effectiveness of its use a synthetic measurement was employed that used the TOPSIS method. The research was based on the statistical data obtained form the Main Statistical Office for the year 2011. Based on the synthetic measure 4 typological groups of regions were singled out due to their productive potential. The measure used ranged from 0.27 to 0.63 and for the majority of voivodships it did not exceed the average value for Poland. The research shows that Poland is also a country that is extremely diverse as regards the effectiveness of use of production capacity of agriculture. The synthetic measures showed here a strong differentiation ranging from 0 to 0.86. Moreover, the research findings indicate that the effectiveness of productive potential in agriculture in the highest in the regions characterised by a high socioeconomic development.

Abstract:
ABSTRACT: Field observation shows a challenge to pull out a cemented casing without cutting it into pieces due to the limitation of pulling force. Required force can often be beyond the capacity of pulling equipment and it can also be beyond the material strength of the casing causing failure if one should be able to use excessive force for removal. For cases where removal of the cemented casing is necessary different approaches have been considered. Introducing grooves to the casing lowers the pulling force to remove it from the cemented wellbore and has been conceptually considered. This method has been demonstrated successfully in lab-scale experiments. The simulations, based on lab-scale geometry, verify the experimental observation and frictional cohesion, the key parameter to control pulling force, is quantified. The field-scale simulation indicates a significant reduction of the pulling force even with small grooves (5 mm width). The peak of the pulling force also illustrates the possibility of pulling a 10-meter grooved casing without cutting it into pieces. This study demonstrates a potential to shorten the non-productive time and save cost on plug and abandonment tasks. 1. INTRODUCTION Pulling a 20-inch surface casing from cemented borehole encounters challenges. In a field scenario, the evaluated pulling force can be more than 1000 tons to trip out a 10-meter surface casing. The downhole pulling tool limits the pulling force up to 350 tons in many situations. This allows only a 3-meter casing section to be pulled out at each run. With such restrictions, a 10-meter casing would be cut into 3 pieces (3 meters for each piece) and pulled out one by one. These restrictions increase the non-productive operational time and cost. Therefore, novel technics are demanded to lower the pulling force if mechanical casing removal is to be applied further. The aim is to pull at least one 10-meter casing at once.

Abstract:
Abstract Control line integrity is fundamental to ensure operability of intelligent completion systems. Damage to control lines can normally occur during string deployment (by shock), or during productive life (by vibration-related fatigue). This work aimed to investigate how encapsulation will affect control line survivability throughout their entire life cycle. Numerical simulations were carried out using geometrical arrangements of control lines typically found in completion valves and tubings. For installation loads, lines were submitted to shock simulations, both inside and outside of protection clamps. The role of flatpack material was studied, as to which kind of material would better absorb impact energy. For productive life loads, the flow-induced vibration was taken into account for high-rate injector wells. Vibration loads were based on force results obtained by Computational Fluid Dynamics (CFD). Structural Finite Element Analysis (FEA) was performed to obtain local tensions to estimate productive life of lines.

Abstract:
The issues of land rents are of particular importance today, the new times have brought them to the fore, now they are new dimensions. Previously in the works of Plato, Xenophon and others it was mentioned but not used as a term. With the entry of capitalism into agricultural politics - everyone talks about it. Agriculture became the main branch of social production, and rent became the object of study. Contribution to the development of the problem have: У. Petit, Fr. F. P?ti, F. Kenet, A. Smith, D. The work of Marx is indisputable. The neoclassical theory advocates a subjective treatment of the problem -opposed to Marx. The reasons are to be sought in the following circumstances: capitalism has undergone fundamental changes; it has entered a stage of global integration; the scientific-technical revolution has raised it to a greater height; new technologies have entered the economy; electronization, robotization, computerization, science has penetrated all spheres of life, has become an immediate productive force; it is rising to a higher level; production is being naturalized, it is becoming a field of application of science. History, however, follows its own logic. The immature economic forms of production do not submit to exact theoretical reflections; as they change, so do our ideas about them.

Abstract:
The challenge of producing high performance, productive and precise machine tools must be accepted by the machine tool industry. These requirements can be reached by increasing the grinding machine parameters, such as the cut depth or the feed rate. Both will increase the grinding force during the grinding process, and can result in an excitation of the machine structure. Based on this excitation, the machine structure shows an undesired dynamic behavior which can result in machine vibrations. These vibrations can cause chatter marks on the workpiece surface, and if large enough can result in a stop in production. To minimize the chance of this situation, the machine user often chooses machine parameters which will not excite the machine structure. This is a disadvantage, because the machine design allows much more efficiency. To employ the complete efficiency of the design, this paper presents an approach which allows the active reduction of possible vibrations during a grinding process.

Abstract:
Reducing the cost of manufacturing products can be realized by high performance, precise and productive machine tools. This goal is often obtained by the user increasing the adjustable machine parameters, which include the feed rate or the cut depth. Both will increase the grinding force during the grinding process, which can result in an excitation of the machine structure. If the excitation is too high, the machine structure can show an undesired dynamic behavior, which can cause the machine to vibrate. These vibrations can result in chatter marks on the work piece surface and if large enough can result in a production stop. One possibility to minimize the chance of excessive vibration is a conservative choice of machine parameters which are well below the optimal set for a particular machine. This paper presents an approach which shows the first results of an active tool holding device aimed at reducing unwanted vibrations resulting from an aggressive parameter choice.

Full text
Abstract:
Abstract As hydrocarbon formation continues, owing to its natural sourcing, technologies have continually emerged on how these hydrocarbons can be effectively produced at a commercial benchmark. Asides its natural drive system, the enhanced oil recovery methods have been one key approach that has been effected towards increasing hydrocarbon's production rate, from its reservoirs. The natural reservoir energy has allowed for about 10% production of original oil in place. And, extending a field's productive life by employing the secondary recovery has further improved production to 20 to 40%, with EOR amounting to about 30 to 60% production. This however, would tell of the impending need towards further developments on increasing upon this production rate. Hence, the approach on using a pneumatic operated assembly with considerations made on onshore wells. This paper seeks to depict a focal on "Pneumatic IOR (Improved Oil Recovery)" as a method to be effected for onshore wells towards improving its productivity. The pneumatic system uses compressed air, contained in a cylinder - through specialized tubing, alongside pressure control systems, that helps regulate the flow and amount of the compressed air; to propel a metallic bar that will act on the reservoir surface. A force of impact, which will induce vibrations inwards, is generated. The mechanical motion of the metal bars for which this compressed air acts upon will provide the travel force, which when it acts on the reservoir surface of interest, will induce geologic stresses. This stresses and vibrations are important constituents in increasing pressure, downhole. Thereby, enabling fluid flow upwards through the wellbore to the surface. And, this will proffer the necessary physics, needed for pressure development downhole, which will be of importance in improving Oil Recovery.

Lazonick, William. Investing in Innovation: A Policy Framework for Attaining Sustainable Prosperity in the United States. Institute for New Economic Thinking Working Paper Series, March 2022. http://dx.doi.org/10.36687/inetwp182.

Full text
Abstract:
“Sustainable prosperity” denotes an economy that generates stable and equitable growth for a large and growing middle class. From the 1940s into the 1970s, the United States appeared to be on a trajectory of sustainable prosperity, especially for white-male members of the U.S. labor force. Since the 1980s, however, an increasing proportion of the U.S labor force has experienced unstable employment and inequitable income, while growing numbers of the business firms upon which they rely for employment have generated anemic productivity growth. Stable and equitable growth requires innovative enterprise. The essence of innovative enterprise is investment in productive capabilities that can generate higher-quality, lower-cost goods and services than those previously available. The innovative enterprise tends to be a business firm—a unit of strategic control that, by selling products, must make profits over time to survive. In a modern society, however, business firms are not alone in making investments in the productive capabilities required to generate innovative goods and services. Household units and government agencies also make investments in productive capabilities upon which business firms rely for their own investment activities. When they work in a harmonious fashion, these three types of organizations—household units, government agencies, and business firms—constitute “the investment triad.” The Biden administration’s Build Back Better agenda to restore sustainable prosperity in the United States focuses on investment in productive capabilities by two of the three types of organizations in the triad: government agencies, implementing the Infrastructure Investment and Jobs Act, and household units, implementing the yet-to-be-passed American Families Act. Absent, however, is a policy agenda to encourage and enable investment in innovation by business firms. This gaping lacuna is particularly problematic because many of the largest industrial corporations in the United States place a far higher priority on distributing the contents of the corporate treasury to shareholders in the form of cash dividends and stock buybacks for the sake of higher stock yields than on investing in the productive capabilities of their workforces for the sake of innovation. Based on analyzes of the “financialization” of major U.S. business corporations, I argue that, unless Build Back Better includes an effective policy agenda to encourage and enable corporate investment in innovation, the Biden administration’s program for attaining stable and equitable growth will fail. Drawing on the experience of the U.S. economy over the past seven decades, I summarize how the United States moved toward stable and equitable growth from the late 1940s through the 1970s under a “retain-and-reinvest” resource-allocation regime at major U.S. business firms. Companies retained a substantial portion of their profits to reinvest in productive capabilities, including those of career employees. In contrast, since the early 1980s, under a “downsize-and-distribute” corporate resource-allocation regime, unstable employment, inequitable income, and sagging productivity have characterized the U.S. economy. In transition from retain-and-reinvest to downsize-and-distribute, many of the largest, most powerful corporations have adopted a “dominate-and-distribute” resource-allocation regime: Based on the innovative capabilities that they have previously developed, these companies dominate market segments of their industries but prioritize shareholders in corporate resource allocation. The practice of open-market share repurchases—aka stock buybacks—at major U.S. business corporations has been central to the dominate-and-distribute and downsize-and-distribute regimes. Since the mid-1980s, stock buybacks have become the prime mode for the legalized looting of the business corporation. I call this looting process “predatory value extraction” and contend that it is the fundamental cause of the increasing concentration of income among the richest household units and the erosion of middle-class employment opportunities for most other Americans. I conclude the paper by outlining a policy framework that could stop the looting of the business corporation and put in place social institutions that support sustainable prosperity. The agenda includes a ban on stock buybacks done as open-market repurchases, radical changes in incentives for senior corporate executives, representation of workers and taxpayers as directors on corporate boards, reform of the tax system to reward innovation and penalize financialization, and, guided by the investment-triad framework, government programs to support “collective and cumulative careers” of members of the U.S. labor force. Sustained investment in human capabilities by the investment triad, including business firms, would make it possible for an ever-increasing portion of the U.S. labor force to engage in the productive careers that underpin upward socioeconomic mobility, which would be manifested by a growing, robust, and hopeful American middle class.

Quak, Evert-jan. The Link Between Demography and Labour Markets in sub-Saharan Africa. Institute of Development Studies (IDS), January 2020. http://dx.doi.org/10.19088/k4d.2021.011.

Full text
Abstract:
This rapid review synthesises the literature from academic, policy, and knowledge institution sources on how demography affects labour markets (e.g. entrants, including youth and women) and labour market outcomes (e.g. capital-per-worker, life-cycle labour supply, human capital investments) in the context of sub-Saharan Africa. One of the key findings is that the fast-growing population in sub-Saharan Africa is likely to affect the ability to get productive jobs and in turn economic growth. This normally happens when workers move from traditional (low productivity agriculture and household businesses) sectors into higher productivity sectors in manufacturing and services. In theory the literature shows that lower dependency ratios (share of the non-working age population) should increase output per capita if labour force participation rates among the working age population remain unchanged. If output per worker stays constant, then a decline in dependency ratio would lead to a rise in income per capita. Macro simulation models for sub-Saharan Africa estimate that capital per worker will remain low due to consistently low savings for at least the next decades, even in the low fertility scenario. Sub-Saharan African countries seem too poor for a quick rise in savings. As such, it is unlikely that a lower dependency ratio will initiate a dramatic increase in labour productivity. The literature notes the gender implications on labour markets. Most women combine unpaid care for children with informal and low productive work in agriculture or family enterprises. Large family sizes reduce their productive labour years significantly, estimated at a reduction of 1.9 years of productive participation per woman for each child, that complicates their move into more productive work (if available). If the transition from high fertility to low fertility is permanent and can be established in a relatively short-term period, there are long-run effects on female labour participation, and the gains in income per capita will be permanent. As such from the literature it is clear that the effect of higher female wages on female labour participation works to a large extent through reductions in fertility.

Full text
Abstract:
We study the labor market effects of the Venezuelan migration shock on female labor market outcomes in Colombia using a Bartik-instrument approach.For our identification strategy we leverage regional variation from pull factors and time variation from push factors. Our findings show that in the labor market, female immigrants can act as substitutes or complements for native-born women depending on native women’s education level; immigrant workers are substitutes in the labor market for native-born low-educated women as they compete for similar jobs. Hence, the low-educated native women’s labor force participation decreases. At the same time, time spent doing unpaid care increases for low-educated native women, possibly further preventing the job search for this group. On the other hand, we find an increase in labor force participation of 1.6 p.p. for highly educated women with minors at home and a 1 p.p. higher likelihood of becoming entrepreneurs due to the migratory shock, which supports the complementary-skill hypothesis. Finally, we don’t find evidence that the migratory shock induced households to outsource more home-production as a means for high-educated women to spend more time at paid work.

Abstract:
Software is a hybrid object in the world research as it is equally a driving force (as a tool), a result (as proof of the existence of a solution) and an object of study (as an artefact). This specific status means we need to define strategies, tools and procedures which are adapted to the various issues it raises. These include the citation of contributions to software design and production, the reproducibility of research results involving software and the wider usage and long-term sustainability of the software heritage created. This opportunity note by the Committee for Open Science's Free Software and Open Source Project Group describes the issues at stake and formulates actionable recommendations.

Abstract:
Agriculture is an important source of employment in Latin America and the Caribbean. In rural areas, some 54.6 per cent of the labour force is engaged in agricultural production. Although much of the region shares the same language and cultural heritage, the structure and scale of the agriculture sector varies significantly from country to country. Based on the review of 131 digital agriculture tools, this report, prepared by GSMA and IDB Lab, provides a market mapping and landscape analysis of the most prominent cases of digital disruption. It highlights some of the major trends observed in five digital agriculture use cases, identifies opportunities for digital interventions and concludes with recommendations for future engagement that could deliver long-term, sustainable economic and social benefits for smallholder farmers.

Abstract:
Armed forces in the Indo-Pacific region remain dependent on weapon systems imported from foreign suppliers. This is despite the efforts of many governments in the Indo-Pacific to implement policies that support the development of local arms industrial capabilities with the aim of increasing self-reliance. This report develops three indicators to give a score and regional ranking of self-reliance to twelve jurisdictions in the Indo-Pacific region: Australia, China, India, Indonesia, Japan, South Korea, Malaysia, Pakistan, Singapore, Taiwan, Thailand and Viet Nam. Overall, this report contributes to knowledge and debates on armament trends and military modernization in the Indo-Pacific. In a region where tensions among neighbours are rising, it further contributes to transparency with regard to levels of self-reliance in domestic arms production, allowing for an independent assessment of the region’s respective arms industries.
