Abstract:

Internet of Things (IoT) systems are complex systems that can manage mission-critical, costly operations or the collection, storage, and processing of sensitive data. Therefore, security represents a primary concern that should be considered when engineering IoT systems. Additionally, several challenges need to be addressed, including the following ones. IoT systems’ environments are dynamic and uncertain. For instance, IoT devices can be mobile or might run out of batteries, so they can become suddenly unavailable. To cope with such environments, IoT systems can be engineered as goal-driven and self-adaptive systems. A goal-driven IoT system is composed of a dynamic set of IoT devices and services that temporarily connect and cooperate to achieve a specific goal. Several approaches have been proposed to engineer goal-driven and self-adaptive IoT systems. However, none of the existing approaches enable goal-driven IoT systems to automatically detect security threats and autonomously adapt to mitigate them. Toward bridging these gaps, this paper proposes a distributed architectural Approach for engineering goal-driven IoT Systems that can autonomously SElf-adapt to secuRity Threats in their environments (ASSERT). ASSERT exploits techniques and adopts notions, such as agents, federated learning, feedback loops, and blockchain, for maintaining the systems’ security and enhancing the trustworthiness of the adaptations they perform. The results of the experiments that we conducted to validate the approach’s feasibility show that it performs and scales well when detecting security threats, performing autonomous security adaptations to mitigate the threats and enabling systems’ constituents to learn about security threats in their environments collaboratively.

Full text

Abstract:

This paper gives two results that show that the dynamics of a time-periodic Lagrangian system on a hyperbolic manifold are at least as complicated as the geodesic flow of a hyperbolic metric. Given a hyperbolic geodesic in the Poincaré ball, Theorem A asserts that there are minimizers of the lift of the Lagrangian system that are a bounded distance away and have a variety of approximate speeds. Theorem B gives the existence of a collection of compact invariant sets of the Euler–Lagrange flow that are semiconjugate to the geodesic flow of a hyperbolic metric. These results can be viewed as a generalization of the Aubry–Mather theory of twist maps and the Hedlund–Morse–Gromov theory of minimal geodesics on closed surfaces and hyperbolic manifolds.

Abstract:

Eagleson’s theorem asserts that, given a probability-preserving map, if renormalized Birkhoff sums of a function converge in distribution, then they also converge with respect to any probability measure which is absolutely continuous with respect to the invariant one. We prove a version of this result for almost sure limit theorems, extending results of Korepanov. We also prove a version of this result, in mixing systems, when one imposes a conditioning both at time 0 and at time $n$.

Abstract:

Knowledge-based systems have often been criticised for the limited theoretical base upon which they are constructed. This view asserts that systems are often developed in an ad hoc, individual way that leads to unmaintainable, unreliable and non-rigorous systems. The last decade, however, has seen an increased effort to produce methodologies to counter this view as well as continued research into validation and verification techniques. This paper presents a brief discussion of some of the important research in knowledge-based system life cycles and development methods. Methodologies are considered and are discussed in light of two sets of quality assurance criteria.

This article considers problems arising from conventional techniques used to diagnose faults in the rolling-element bearings of rotor-bearing systems, with dampers used in centrifugal milk processing machinery. Such machines include milk separators and related processing machinery. The article asserts that where the rotor-bearing system is equipped with vibration dampers, conventional fault diagnostic measurements produce inadequate results. Hence, for rotor-bearing systems of this type, this article suggests a different way to diagnose faults in bearings and monitor conditions.

Abstract:

In this paper, we give necessary and sufficient conditions to ensure the validity of confidence intervals, based on the central limit theorem, in simulations of highly reliable Markovian systems. We resort to simulations because of the frequently huge state space in practical systems. So far the literature has focused on the property of bounded relative error. In this paper we focus on ‘bounded normal approximation’ which asserts that the approximation of the normal law, suggested by the central limit theorem, does not deteriorate as the reliability of the system increases. Here we see that the set of systems with bounded normal approximation is (strictly) included in the set of systems with bounded relative error.

Abstract:

The analysis of a sample of characteristic commercial shop signs in today's Limassol, Cyprus, asserts their anchorage function as syncretic/polysemiotic texts relying upon the synergy of semiotic systems, in their commercial and broader informational function. The study of intersemiosis, i.e. of the translation between pictorial and linguistic semiotic systems and their hierarchy, can provide the basis for an in-depth semiotic study of the socio-economic and historical-aesthetic landscape of the city. This study offers a preliminary methodological separation of sign systems on the shop signs in Limassol, showing up the ways intersemiosis remains the standard historical communication method of shop signs since the advent of mass commerce.

Abstract:

During the last two decades, Asian countries have attempted to establish several aligned academic credit systems as part of the harmonization process of their higher education systems. However, these systems have not been widely used among universities in the Asian region. This article analyzes the current trends in credit-related governmental regulations and university systems in 24 Asian countries and territories. Moreover, it asserts the concept of “Asian Academic Credits,” (hereafter, AACs) as a new widely effective aligned system of academic credit transfer within Asia and also with other regionally aligned credit systems in the world. AACs can serve as one of the vital components for a new era of Asian higher education that provides a regionally aligned, flexible, and innovative learning environment for students throughout the entire Asian region.

Abstract:

In his book Making Globalization Work, Joseph Stiglitz proposes reforms to address problems arising from the global spread of capitalism, problems that he asserts are not inherent to globalization or capitalism but are due to the way those systems have been “managed.” Conversely, postcolonial feminist theorist Chanda Talpade Mohanty’s analysis of those same systems demonstrates that capitalism is not compatible with global justice. In this essay I use Mohanty’s analysis to argue that Stiglitz’s proposed reforms would not achieve his stated goals and that the global capitalist system must be dismantled if global justice is to be achieved.

Full text

Abstract:

This paper asserts that neoliberal forms of governance are increasingly found in construction systems in Spain, a fact which becomes especially problematic when considering vernacular construction systems. Technological management and policy are both becoming more focussed on the promotion and consolidation of ‘expert systems’ at the expense of ‘different’ (and in particular) vernacular systems, which are processes which influence minds, and fundamentally shape subsequent actions. This paper adopts an ethnographic approach, undertaking investigation into the complexity of commonly found building systems, based upon empirical evidence gathered in the region of Catalonia. Focussing research on local vernacular construction systems reveals the extent to which the operation of distinct sets of managing ‘technologies’—embedded in specific practices such as auditing—becomes instrumental in shaping local construction practices. Currently, locally distinctive practices are deeply impacted by social influences generated far away, which have the consequences of significantly influencing, diluting, or even erasing vernacular building systems, even where these represent an important source of sustainable building techniques.

Abstract:

The holographic bound asserts that the entropy S of a system is bounded from above by a quarter of the area [Formula: see text] of a circumscribing surface measured in Planck areas: [Formula: see text]. This bound is widely regarded a desideratum of any fundamental theory of nature. In fact, the bound is known to be valid for generic systems in three spatial dimensions. However, in this essay we explicitly show that hyperentropic systems (those violating the holographic entropy bound) do exist in higher-dimensional spacetimes. This is a new and surprising result which should be taken into account in the construction of any fundamental quantum theory of gravity.

Full text

Abstract:

To answer the interaction problem, dual-process theories of reasoning must explain how seemingly disparate reasoning systems affect each other and underlie the apparent unity of subjective experience. Wastell (2014) proposes complex emergence modular theory, which asserts that complex virtual reasoning modules emerge from basic reasoning modules. We contend that Wastell’s proposal fails to address the interaction problem. First, we claim that the attempt to integrate emergence with virtual modules proliferates the interaction problem instead of solving it. Second, we argue that there is no interaction problem in human reasoning if “emergence” is employed in accordance with typical applications of complex systems theory in cognitive science and psychology. Alternatively, we suggest that in order to understand human reasoning within a complex systems framework, researchers should forego conceiving of reasoning as informationally encapsulated modular systems, and instead investigate system state transitions.

It further asserts that social ordering deriving from transnational governance that is democratic will be legitimate.

Abstract:

The debate between H.L.A. Hart and Lord Devlin on the limits of the law is a significant contribution to legal theory, ethical theory, and social philosophy. Hart's "separation thesis" argues that moral considerations are unnecessary for the efficient functioning of legal systems, while Devlin's "The Enforcement of Morals" asserts that law and morality are inseparable and dependent on each other. This conflict has significant implications for legal theory and practices, including the role of ethical considerations in legal systems, the debate on individual liberty and societal coherence, the decision-making process in legal matters, and the significance of embracing the present moment. The Hart-Devlin argument influences ongoing discussions on topics such as decriminalization, marriages, and criminal justice.

For today's practitioners, the paper asserts that architectural works are geometric constructs and reminds them that CAD is based on the arithmeticization of geometry.

Abstract:

The study aimed to evaluate the implementation, and problems encountered in the implementation of Philippine National Police Electronic – Project Systems in Lipa City Batangas. The descriptive research design was used employing a self-made survey questionnaire distributed purposively to 120 internal stakeholders as the respondents of the study. The basic statistical tools were used to interpret and analysed the data gathered. The study revealed that e-Subpoena, e-Gallery, e-Warrant System, and e-Blotter Report are implemented in Lipa City, Batangas within the indicators of an effective implementation plan. However, the study also revealed that the stakeholders encountered serious problems in the implementation of PNP’s e-Project Systems within the bounds of the criteria used. This study asserts that although the PNP’s e-Project Systems in Lipa City Batangas are implemented, the regular conduct of capability building is necessary for the monitoring, supervision and management of the project.

Abstract:

We construct a quantumness witness following the work of Alicki & van Ryn (AvR). We reformulate the AvR test by defining it for quantum states rather than for observables. This allows us to identify the necessary quantities and resources to detect quantumness for any given system. The first quantity turns out to be the purity of the system. When applying the witness to a system with even moderate mixedness, the protocol is unable to reveal any quantumness. We then show that having many copies of the system leads the witness to reveal quantumness. This seems contrary to the Bohr correspondence, which asserts that, in the large-number limit, quantum systems become classical, whereas the witness shows quantumness when several non-quantum systems, as determined by the witness, are considered together. However, the resources required to detect the quantumness increase dramatically with the number of systems. We apply the quantumness witness for systems that are highly mixed but in the large-number limit that resembles nuclear magnetic resonance (NMR) systems. We make several conclusions about detecting quantumness in NMR-like systems.

With few models on which to draw, the EAC must find a way to address the convergence of the telecommunications and financial sectors to enable maximum benefits from mobile banking, especially for the poor.

Abstract:

This paper treats the Pinsker algebra of a dynamical system in a way which avoids the use of an ordering on the acting group. This enables us to prove some of the classical results about entropy and the Pinsker algebra in the general setup of measure-preserving dynamical systems, where the acting group is a discrete countable amenable group. We prove a basic disjointness theorem which asserts the relative disjointness in the sense of Furstenberg, of $0$-entropy extensions from completely positive entropy (c.p.e.) extensions. This theorem is used to prove several classical results in the general setup. For example, we show that the Pinsker factor of a product system is equal to the product of the Pinsker factors of the component systems. Another application is to obtain a generalization (as well as a simpler proof) of the quasifactor theorem for $0$-entropy systems of Glasner and Weiss.

Full text

Abstract:

I propose that archaeologists, in pursuing a renewed interest in studying technological change, construct general theories and models of invention processes. As an example, this paper presents the “cascade” model for investigating invention processes in the context of “complex technological systems.” Building on the recognition that the vision of a new complex technological system is often obvious, the cascade model asserts that the hard work of invention takes place in a series of invention “cascades,” as people strive to achieve acceptable values of a new technology's core or critical performance characteristics during life-history processes (i.e., fashioning a prototype, replication or manufacture, use, and maintenance). The cascade model is illustrated by means of the nineteenth-century electromagnetic telegraph, and implications are drawn for studying invention processes in the complex technological systems of small-scale societies.

Full text

Abstract:

AbstractDuring the design of complex systems, a design process may be subjected to stochastic disruptions, interruptions, and changes, which can be described broadly as “design impulses.” These impulses can have a significant impact on the transient response and converged equilibrium for the design system. We distinguish this research by focusing on the interactions between local and architectural impulses in the form of designer mistakes and dissolution, division, and combination impulses, respectively, for a distributed design case study. We provide statistical support for the “parallel character hypothesis,” which asserts that parallel arrangements generally best mitigate dissolution and division impulses. We find that local impulses tend to slow convergence, but systems also subjected to dissolution or division impulses still favor parallel arrangements. We statistically uphold the conclusion that the strategy to mitigate combination impulses is unaffected by the presence of local impulses.

Full text

Abstract:

To secure information systems, the security risks and requirements must be clearly understood before the proper security mechanisms can be identified and designed. Todayâ€™s security requirement specifications are generally incomplete and narrowly focused, which leads to ineffective security designs of information systems. The author asserts that multiple viewsâ€”management, threat, resource, process, assessment, and legalâ€”of information systems provides an opportunity for a better understanding of security risks and requirements. In this paper, the author proposes a six-view perspective of a system security framework to identify a more complete set of security risks and requirements. The proposed framework presents a synergistic view of the system security in which the author presents an extensive list of heuristics/guidelines under each view, discussing security issues, risks, and requirements. Through a case study, the authors shows that a multiple view perspective of system security is effective in determining a more complete set of security requirements than the traditional approach of focusing on threats alone.

Abstract:

AbstractWe consider the elliptic equation {-\Delta u=u^{q}|\nabla u|^{p}} in {\mathbb{R}^{n}} for any {p>2} and {q>0}. We prove a Liouville-type theorem, which asserts that any positive bounded solution is constant. The proof technique is based on monotonicity properties for the spherical averages of sub- and super-harmonic functions, combined with a gradient bound obtained by a local Bernstein argument. This solves, in the case of bounded solutions, a problem left open in [2], where the case {0<p<2} is considered. Some extensions to elliptic systems are also given.

Abstract:

The main problem that postmodernism faces in solving its own problems and in achieving its own goals is the relationship between arguments expressed in terms of a rational paradigm and attempts to avoid the system of rationalism. Analysis of postmodern experiences shows that new concepts, signs, communications, and systems of thought that can give new, fundamentally working models will never be born in the same state of thought, in the same images and their meanings. In this context, it is important to vesnitskii experience different experiences and awareness of reality, and asserts its right to participate in shaping the world's future.

Abstract:

This paper is a brief but critical survey of some theories of organizational culture. It outlines the theories of culture borrowed from anthropology by social scientists interested in 'complex organizations', and locates these theories in an historical debate regarding their 'proper' use. The paper argues the need for a conceptual distinction between culture and social structure, and asserts that the culture of organizational life cannot be analyzed in terms of a universal unitary concept. The argument concludes by suggesting 'conceptual tools' for interpreting culture — symbol, ideational systems, myth and ritual — and how they might be used in analysis.

Abstract:

We study systems which in characteristic coordinates have the formwhere A is a k × k diagonal matrix with distinct real eigenvalues. The nonlinearity F is assumed to be asymptotically homogeneous in the sense, that it is a sum of two terms, one positively homogeneous of degree one in u and a second which is sublinear in u and vanishes when u = 0. In this case, F(t, x, u(t)) is meaningful provided that u(t) is a Radon measure, and, for Radon measure initial data there is a unique solution (Theorem 2.1).The main result asserts that if μn is a sequence of initial data such that, in characteristic coordinates, the positive and negative parts of each component, , converge weakly to μ±, then the solutions coverge weakly and the limit has an interesting description given by a nonlinear superposition principle.Simple weak converge of the initial data does not imply weak convergence of the solutions.

Abstract:

The effect of user participation on system success is one of the most studied topics in information systems, yet still yields inconclusive results. Contingency-based concepts attempt to resolve this issue by providing a plausible explanation which indicates that users can only generate expected results when there is a need for users to participate in the development process. As a different approach, this study adopts a mediating perspective and asserts that influence due to the effectiveness of participation determines the final outcomes. Based on control theory, and viewing user participation in reviews as one kind of control, we propose that the influence users can generate through participation determines project outcomes. Data collected from 151 information systems personnel confirms the relationships and that an ability to achieve quality interactions among developers and users heightens the achievement of user influence.

Abstract:

This article considers the relationship between customary law (kastom) and the official legal system in Vanuatu. It looks at the limitations of the reasons propounded for the lack of integration of customary law and the official legal system and argues that the integration should be a two-way process. The author asserts that a new methodological approach is required to assess the issue regarding the current extent of integration, desirability of integration and capacity for integration of the two systems. Rather than merely analysing case law or legislation, the author argues that the reality behind this picture needs to be investigated and empirical research undertaken.

A classical result of Paley and Marcinkiewicz asserts that the Haar systemh=hkk≥0on0,1forms an unconditional basis ofLp0,1provided1<p<∞. That is, if𝒫Jdenotes the projection onto the subspace generated byhjj∈J(Jis an arbitrary subset ofℕ), then𝒫JLp0,1→Lp0,1≤βpfor some universal constantβpdepending only onp. The purpose of this paper is to study related restricted weak-type bounds for the projections𝒫J. Specifically, for any1≤p<∞we identify the best constantCpsuch that𝒫JχALp,∞0,1≤CpχALp0,1for everyJ⊆ℕand any Borel subsetAof0,1. In fact, we prove this result in the more general setting of continuous-time martingales. As an application, a related estimate for a large class of Fourier multipliers is established.

Abstract:

This study tackles the complex task of constructing a dynamic model of a navigator, planning their experience trajectory, and making decisions under navigational risks in the maritime industry using automated control systems. the proposed mathematical model accounts for individual skills, experiences, and personalities, while considering unpredictable industry dynamics. the study asserts the importance of adaptable automated control systems capable of simulating navigation risk situations and determining suitable career and development paths. in addition, it discusses the importance of assessing external factors such as economic, technological, and regulatory changes and ensuring compliance with industry standards, data security, and privacy. the paper further emphasizes the necessity for scalability and flexibility, as well as the seamless integration of automated systems with existing organizational infrastructures. the study concludes that the proposed model, optimized for the "safety of navigation" parameter using the Pontryagin maximum principle, enhances recruitment processes, creates comprehensive professional profiles for seafarers, and supports career development. the paper suggests the potential of this model's application in other maritime and related professions, ultimately enhancing individualized training and operational efficiency.

Full text

Abstract:

The query containment problem is a fundamental algorithmic problem in data management. While this problem is well understood under set semantics, it is by far less understood under bag semantics. In particular, it is a long-standing open question whether or not the conjunctive query containment problem under bag semantics is decidable. We unveil tight connections between information theory and the conjunctive query containment under bag semantics. These connections are established using information inequalities, which are considered to be the laws of information theory. Our first main result asserts that deciding the validity of a generalization of information inequalities is many-one equivalent to the restricted case of conjunctive query containment in which the containing query is acyclic; thus, either both these problems are decidable or both are undecidable. Our second main result identifies a new decidable case of the conjunctive query containment problem under bag semantics. Specifically, we give an exponential-time algorithm for conjunctive query containment under bag semantics, provided the containing query is chordal and admits a simple junction tree.

Abstract:

Using federated learning, which is a distributed machine learning approach, a machine learning model can train on a distributed data set without having to transfer any data between computers. Instead of using a centralised server for training, the model uses data stored locally on the device itself. After that, the server uses this model to create a jointly trained model. Federated learning asserts that privacy is preserved because no data is sent. Botnet attacks are detected using on-device decentralised traffic statistics and a deep autoencoder. This proposed federated learning approach addresses privacy and security concerns about data privacy and security rather than allowing data to be transferred or relocated off the network edge. In order to get the intended results of a previously centralised machine learning technique while also increasing data security, computation will be shifted to the edge layer. Up to 98% accuracy is achieved in anomaly detection with our proposed model using features like MAC IP and source/destination/IP for training. Our solution outperforms a standard centrally managed system in terms of attack detection accuracy, according to our comparative performance analysis.

Abstract:

The article evaluates the accuracy of the approximation of the aerodynamic force coefficients (moments) of the projectile and atmospheric parameters, which are significantly nonlinear. The aerodynamic force coefficients (moments) of the 155-mm Assegai M2000 projectile of the South African company Denel Naschem and atmospheric parameters defined by the international standard ISO 2533:1975/Add.1:1985(en) Standard Atmosphere are taken as basis. The estimation of the accuracy of the approximation of the tabular values is presented through the relative error (misalignment) between the given tabular data and the values of the approximated function of the aerodynamic force coefficients (moments). Analytical functions are used as approximating functions, such as the sum of a support function (error function) and a set of basic functions (Gaussian functions), which makes it possible to obtain an approximating function continuously differentiated on the segment of the change in the projectile flight parameter, which can be represented by a single expression. In the Maple software environment, analytical functions (error functions and Gaussian functions) were approximated to the tabulated values of the aerodynamic coefficients of forces (moments) of the 155-mm Assegai M2000 projectile. The obtained values of the single analytical functions of force coefficients (moments) and atmospheric parameters can be used to solve the problems of calculating firing tables, preparing data using ballistic integrating algorithms (ballistic calculators) for firing existing, new artillery systems and those systems being modernized. It is shown that by iterative procedures of approximation of tabular data of aerodynamic force coefficients (moments) and parameters of the atmosphere, it is possible to construct analytical functions in the form of a continuous function of the projectile flight parameter within the entire range of its change, ensuring the given accuracy of its approximation to the tabular data.

Abstract:

Electronic health records (EHRs) are the future of the healthcare industry; however, insufficient attention is paid to where and how the hardware systems that support EHR software are integrated in the existing environment. The physical implementation of EHRs is an underlying component of the technology program that may pose barriers and/or gateways to EHR adoption in terms of patient safety and satisfaction, clinical usability of the EHR system, cultural acceptance, and organizational workflow. After confirming that environmental interventions are most effective when coupled with cultural programs, this article asserts that hardware is a necessary complement to EHR software implementation if usage is to progress strategically and ergonomically. This article then seeks to explain how, based on evidence-based design (EBD) decisions, the built environment that supports EHR software can enhance or hinder communication. The findings of this paper posit that when EHR hardware is designed ergonomically and with provider-patient communication at the forefront of point-of-care services, EHR usage in the healthcare environment can improve the quality of health services delivery. This article is the result of a literature review, case studies, academic lectures, healthcare informatics webinars, and discussions with architects, interior design professionals, and corporate EHR leaders.

Abstract:

Mounting evidence of chemical disequilibria in the Venusian atmosphere has heightened interest in the search for life within the planet’s cloud decks. Balloon systems are currently considered to be the superior class of aerial platform for extended atmospheric sampling within the clouds, providing the highest ratio of science return to risk. Balloon-based aerial platform designs depend heavily on payload mass and target altitudes. We present options for constant- and variable-altitude balloon systems designed to carry out science operations inside the Venusian cloud decks. The Venus Life Finder (VLF) mission study proposes a series of missions that require extended in situ analysis of Venus cloud material. We provide an overview of a representative mission architecture, as well as gondola designs to accommodate a VLF instrument suite. Current architecture asserts a launch date of 30 July 2026, which would place an orbiter and entry vehicle at Venus as early as November 29 of that same year.

Full text

Abstract:

For more than a decade, healthcare reform has emphasized coordinated “patient-centered care”. To that end, policymakers have invested in integration of healthcare providers’ information flows. Research has studied healthcare providers’ information needs but overlooked communicative exchanges among participants in coordinating treatment plan decisions. Consequently, although medical literature asserts that patients should depend on information exchange with healthcare providers to enable participation in treatment plan decisions, the assertion has not been tested. In this paper, the authors conduct an empirical study to elucidate the structure of actors’ communications in support of their information dependencies. The findings illustrate that although patients are well connected through personal contact with healthcare providers, patients are disenfranchised from integrated healthcare information systems (IS) and the potential of IS to support patients’ participation in coordinated “patient-centered care” decisions. Furthermore, knowledge asymmetry between patients and healthcare providers should be considered in the selection and design of healthcare IS.

Abstract:

In the Critique of Pure Reason, Kant criticizes his predecessors, specifically Locke and Leibniz, in their one-sided reductions of representation to a single faculty. In his 1802 dialogue Bruno, Schelling develops this discussion into a criticism of Kant’s own one-sided idealism. Focusing on these developments makes clear the manner in which Schelling sees himself as advancing beyond both pre-Critical realisms and Kant’s transcendental idealism. He subsumes realism and Kantian idealism within his own absolute standpoint, providing a ground and rationale for both types of philosophical system as independent approaches, and he asserts that the ultimate foundation and unity of these systems of philosophy is in the absolute which is beyond conceptual thought.

In this essay Jay Gillen draws on his experiences as a facilitator of the Algebra Project to argue that only a generation of young people—and particularly young people in poverty—has the potential and the necessary boldness to break the caste system of schooling. In this struggle, they follow their ancestors who "earned" the insurrections required to break the slave and sharecropper systems. How young people in poverty interpret Obama's election, asserts Gillen, will determine what Obama means for educational justice.

This article asserts that the normative, institutional and policy framework of an economy moulds the structure and performance of its innovation system. Three case studies of industry-higher education partnerships in South Africa's biotechnology sector challenge both the notion of a simple convergence within and between national innovation systems and the idea of an unproblematic adoption of ‘best practice’ at the organizational level. The contribution of industry-higher education partnerships to greater economic efficiency is shaped by the social conditions in which they are embedded. Rising levels of competition and new policy initiatives provide the fundamental impetus for collaboration and generate varying patterns of strategic alliances between governmental agencies, industry and higher education institutions.

Lipset sets out to demonstrate the distinct differences between American and European notions of liberalism and conservatism. Tocqueville's coined term “American exceptionalism” reaffirms that social, political, and religious systems took a unique form in the United States. American liberals and conservatives alike have sought to extend the “good society” based on the Protestant ethic worldwide, though, ironically, both see their domestic opponents as advocates of immoral policies. The author concludes with an assessment of the current global movement toward classical liberalism: “We are all liberals-even the socialists and communists,” he asserts. As economic liberalism is not a panacea for the world's problems, Lipset predicts a return to the state-centric world in the not-so-near future.

Abstract:

The slowness with which the European Union asserts its role as a mediator in the international sphere must not be Romania’s own policy. Many EU member states or organisations have developed their own systems to provide stability as a facilitator for peace processes or have developed early warning and conflict prevention mechanisms. Romania’s membership in various external structures enables it to use international expertise in creating and implementing internal structures capable of involving the state in the prevention and resolution of conflicts in the Black Sea region or in other areas of the world. The article analyses Romania’s potential to act regionally as a mediator and to generate stability and security if such a conflict approach is embraced.
