Upholding the 4th estate—exploring the corporate governance of the media ownership form of business foundations

ABSTRACT Whereas media ownership issues have interested scholars for decades, research has largely ignored the implications of specific ownership forms on the corporate governance of media companies, that is, how these companies are directed and controlled. This article attempts to address this gap by exploring the corporate governance of the ownership form of business foundations—a type of ownership that is increasing in different countries around the world. We analyze the corporate governance of three business foundations in the Swedish newspaper sector that together hold 26% of the market and outperform their industry peers. The control function, which is at the heart of corporate governance, is typically performed by companies’ owners. However, foundations do not have a physical person as owner; thus, this control function is replaced by the foundation’s charter, which stipulates the aim of the foundation’s business activities. When steered by professional top management, the charter’s long-term orientation facilitates the careful implementation of strategic directions without short-term performance pressures. We conclude the article by outlining several advantages and disadvantages of this ownership form for the media industry.
Enterprise Modelling: The Next Steps

Enterprise modelling is at the core of Information Systems and has been a subject of intensive research for about two decades. While the current state of the art shows signs of modest maturity, research is still facing substantial challenges. On the one hand, they relate to shortcomings of our current knowledge. On the other hand, they are related to opportunities of enterprise modelling that have not been sufficiently addressed so far. This paper presents a personal view of future research on enterprise modelling. It includes requests for solving underestimated problems and proposes additional topics that promise to promote enterprise models as more versatile tools for collaborative problem solving. In addition to that, the paper presents requests for (re-)organising research on enterprise modelling in order to increase the impact of the field.
SUPPLY CHAIN FINANCE, A SOLUTION TO IMPROVE BUSINESS EFFICIENCY

The social and economic environment of the Romanian companies is under the influence of several factors, among them being the announced protectionist measures which are reducing the exports, the unknown impact of the Brexit, the probability of the incoming recession in the U.S., the uncertainty of the legal and political climate, the lack of stability and predictability in the Romanian legislation etc. The companies are facing the problem of lacking capital and the necessity of reducing their working capital. Until now, the only viable solution was stocks reduction, but supply chain finance (SCF) can be the solution to reduce the payment term, reduce risk, working capital optimization and to improve the relationship between supplier and buyer. The mechanism of the SCF enables the suppliers to benefit from the financing facilities of the buyer, by leveraging the buyer’s better credit rating. Key words: Factoring, working capital, reverse factoring, supply chain finance, invoice discounting, business efficiency
Shopping centres beyond purchasing of luxury goods: a tourism perspective

ABSTRACT This study sought to identify the main dimensions of shopping experiences shared online by tourists after visiting luxury shopping centres and to ascertain the main narratives linked with any dissatisfaction these tourists express. A mixed content analysis was conducted on 1050 reviews describing shopping experiences in seven luxury shopping centres. The results reveal the existence of eight dominant themes: shopping, luxury, day, place, food, walk, expensive (goods) and people. The main theme linked with dissatisfaction is that of expensive. The concept map of these themes confirms that experiences in luxury shopping centres diverge from those in general goods shopping centres.
Feedback design for linear control systems with exogenous and system disturbances: Robust statement

A simple but versatile approach to robust control design for linear systems with system and exogenous disturbances is proposed. The proposed approach is based on the technique of linear matrix inequalities and the concept of invariant ellipsoids. The approach is easily implemented computationally, its efficacy is demonstrated on the benchmark example of the F-16 aircraft model.
Design consideration for three-axis MEMS accelerometers using an asymmetric proof mass

This paper presents three different designs of three-axis accelerometers using a thick epitaxial surface micromachining process. The designs have a common serpentine spring topology, providing a resonant frequency of around 1.5 kHz, with a spring length of 350 μm and have capacitive sensitivities in the region of 5 to 10 fF/g for the X and Y sensing. The Z-axis sensing is performed by means of torsional springs of 370 μm in length. The sensing techniques include varying gap differential combs for the XY-axes; varying gap differential electrodes and varying overlap area for the Z-axis. The acceleration range for all designs is ±10 g and the overall sensitivity was increased by having a large nominal capacitance.
"Convex Until Proven Guilty": Dimension-Free Acceleration of Gradient Descent on Non-Convex Functions

We develop and analyze a variant of Nesterov's accelerated gradient descent (AGD) for minimization of smooth non-convex functions. We prove that one of two cases occurs: either our AGD variant converges quickly, as if the function was convex, or we produce a certificate that the function is "guilty" of being non-convex. This non-convexity certificate allows us to exploit negative curvature and obtain deterministic, dimension-free acceleration of convergence for non-convex functions. For a function $f$ with Lipschitz continuous gradient and Hessian, we compute a point $x$ with $\|\nabla f(x)\| \le \epsilon$ in $O(\epsilon^{-7/4} \log(1/ \epsilon) )$ gradient and function evaluations. Assuming additionally that the third derivative is Lipschitz, we require only $O(\epsilon^{-5/3} \log(1/ \epsilon) )$ evaluations.
Ultrafast spin dynamics in ferromagnetic nickel.

Fast magnetization changes can be achieved in a ferromagnet using optical pulses. Such changes which are due to an increase of the spin temperature above the Curie point are generally induced by the temperature elevation of the lattice induced by pico-nanosecond pulses [1,2]. In this case, the electron and phonon population are in equilibrium, and the delay between spin and lattice dynamics has been attributed to spin phonons interactions. As reported in this paper, the initial hot electron distribution created by femtosecond pulses can induce an ultrafast spin heating via electron-spin collisions. It is shown that in the first picosecond a new situation occurs where the electrons, spins and phonons are out of equilibrium and where an ultrafast demagnetization takes place [3].
Investment of financially distressed firms: The role of trade credit

We study the relationship between net trade credit and firms' investment levels, focusing on financially distressed firms. First, we introduce a theoretical model to predict the role played by net trade credit as a coordination device differentiating firms by their degree of financial distress. Then, we test these predictions by using a large panel of more than 10 million firms in 23 EU countries over the period 2004-2014. Our main result is that, whereby net trade credit has an overall negative impact on capital formation due to liquidity effects, the effect is less pronounced for firms that are in financial difficulties. The main explanation is that through capital expenditures distressed companies try to maintain vital business relations with their customers in order to participate in the final profits via trade credit repayments.
Craft and industry : investigating the nature and value of collaboration between crafts practitioners and manufacturers within the new product development process

The thesis investigates the nature and value of crafts knowledges in the context of the new product development (NPD) process. Its aim is to develop an empirically-derived understanding of the potential benefits for both crafts practitioners and manufacturers of collaborative NPD, and of the factors influencing its outcome.The study adopted a grounded theory methodology, deriving theory from the lived experiences of participants in collaborative projects. Crafts practitioners, crafts-based manufacturers and designers with differing backgrounds and motivations were interviewed in relation to their own perceptions and experiences of the NPD process and its management. From this study, a network of inter-related case studies was developed, enabling comparative evaluation to be undertaken. Data analysis was conducted in relation to an emerging theoretical framework which drew upon an ongoing, critical review of literature relating to theories of design management, cognitive psychology, communication in design, and craft and design epistemologies. The thesis finds that the manufacturers' NPD activities were facilitated by the involvement of crafts practitioners, which resulted in significant intangible gains in addition to successful product outcomes. Collaboration was discovered in exemplary cases to enhance competitiveness, mobilising latent knowledge-based resources and learning capabilities, whilst initiating developments in organisational culture. For the crafts practitioners interviewed, the industrial environment was discovered to offer new affordances and constraints, which could then become a catalyst to creativity.In summary, the research: identifies the impact of crafts knowledges on the NPD process and its intangible outcomes. proposes strategies for the rejuvenation of the crafts-based industries. identifies problems inherent in collaboration and factors influencing project outcome. proposes implications for practitioners, manufacturers, educators and training providers. critiques theoretical advocacy for crafts-industry collaboration.
Hopf Algebras in Quantum Computation

In this thesis, we use string diagrams to study the theory of Hopf algebras in the context of Categorical Quantum Mechanics. First, we treat the theory of representations of a Hopf algebra diagrammatically. The category of representations of a quasitriangular Hopf algebra Rep(H) is a braided tensor category and can be understood as a process theory of particles in Topological Quantum theory. We provide diagrammatic proofs of equivalences relating the Drinfeld center construction on Rep(H) to the category of Quantum double modules Rep(DH). We then use similar tools to generalize Kitaev’s lattice models for Topological Quantum computation and give a categorical perspective on Permutational Quantum computation. Finally, we discuss functorial semantics in the context of quantum computation, by constructing a braided language for stabilizer quantum gates.
Omphalocele in three generations with autosomal dominant transmission

We report a family with nine subjects over three generations affected with an omphalocele requiring surgical intervention within the first few days of life. Because of the vertical transmission and male to male inheritance in our family, we conclude that an autosomal dominant gene caused the omphalocele in the affected family members. The paternal great grandfather of the proband was not clinically affected but produced two children with omphaloceles with different spouses.

A flexible three-phased object-oriented data mining approach for sequential transactions

Recently, the object concept has been very popular and used in a variety of applications, especially for complex data description. In the past, data mining is most commonly used in attempts to induce association rules from transaction data. As to object-oriented data mining, Huang et al proposed an algorithm for finding interand intra-class knowledge. This paper will improve it and propose a modified mining algorithm to derive sequential patterns from object-oriented data with more pruning effects. There are three kinds of knowledge to be discovered: sequential inter-class patterns, intra-class association rules and sequential inter-intra patterns. There are three phases in the algorithm, with each for a kind of knowledge. The results from the previous phase can be used to prune candidates in the current phase. The candidates generated will thus become much less than those without pruning. Besides, the approach can be easily modified to stop at an intermediate phase if only the desired kind of knowledge is to be obtained. An example is also given to illustrate the proposed algorithm.
Reaper‐induced dissociation of a Scythe‐sequestered cytochrome c‐releasing activity

Reaper is a potent apoptotic inducer critical for programmed cell death in the fly Drosophila melanogaster. While Reaper homologs from other species have not yet been reported, ectopic expression of Reaper in cells of vertebrate origin can also trigger apoptosis, suggesting that Reaper‐responsive pathways are likely to be conserved. We recently reported that Reaper‐induced mitochondrial cytochrome c release and caspase activation in a cell‐free extract of Xenopus eggs requires the presence of a 150 kDa Reaper‐binding protein, Scythe. We now show that Reaper binding to Scythe causes Scythe to release a sequestered apoptotic inducer. Upon release, the Scythe‐sequestered factor(s) is sufficient to induce cytochrome c release from purified mitochondria. Moreover, addition of excess Scythe to egg extracts impedes Reaper‐induced apoptosis, most likely through rebinding of the released factors. In addition to Reaper, Scythe binds two other Drosophila apoptotic regulators: Grim and Hid. Surprisingly, however, the region of Reaper which is detectably homologous to Grim and Hid is dispensable for Scythe binding.
Do Internet-Based Promotion Efforts Work? Evaluating MarketMaker

MarketMaker is one of the most extensive collections of electronic searchable food industry-related data engines in the country with over 17,500 profiles, including over 7,600 agricultural producers. This article summarizes the results of a survey that assesses the impact of MarketMaker on agricultural producers registered on the website. Results indicate that, by participating on MarketMaker, producers' annual sales have increased by about $121. The number of contacts received, new customers gained, and increased annual sales due to participation in the site are positively related to self-registration on the MarketMaker site, time since registration, and monthly time devoted to the website .
JPSS-1 VIIRS prelaunch RSB/DNB RVS characterization and water vapor correction

The accuracy of pre-launch VIIRS response versus scan angle (RVS) characterization is vitally important to the quality of calibrated radiance products. The RVS correct the optical system’s scan angle dependency with respect to the calibrator scan angle. In this document, we describe the methodology used in JPSS-1 RSB RVS characterization and the efficacy of MODTRAN5 in water vapor correction. The RVS is characterized using a 2nd order polynomial fit over the measured scan angles. The results show high fitting accuracy for all bands except for M9 due to water vapor absorption. To improve M9 RVS, MODTRAN®5 is used to correction water vapor absorption variation during the RVS measurements. This correction greatly reduced M9 RVS characterization uncertainty with a RVS that is up to 0.4% difference compared with RVS prior to water vapor correction.
Analysis of excitation source features of speech for emotion recognition

During production of emotional speech there are deviations in the components of speech production mechanism when compared to normal speech. The objective of this study is to capture the deviations in features related to the excitation source component of speech, and to develop a system for automatic recognition of emotions based on these deviations. The emotions considered for this study are: anger, happy, neutral and sad. The study shows that there are useful features in the deviations of the excitation source features at subsegmental level, and they can be exploited to develop an emotion recognition system. A hierarchical binary decision tree approach is used for classiﬁcation.
COSTS OF HEALTH CARE AND SOCIAL SERVICES DURING THE FIRST YEAR AFTER ISCHEMIC STROKE

Objectives: Knowledge of resource use and costs can be useful when evaluating existing services or planning new services. This study investigates the use of health care and social services during the first year after a stroke. Total costs are calculated, costs are compared across subgroups of patients, and resource items of major importance for the total costs are identified. Methods: The study is based on a database comprising data on all stroke patients admitted to a university hospital in Copenhagen, Denmark, over a 1-year period, 1994–95. Patients were followed for 1 year after the stroke, and data on resource use during and after hospitalization were collected prospectively at interviews. This paper focuses on a subset of 385 patients who were admitted because of cerebral infarct or unspecified stroke. Results: The mean cost, based on all patients, of health care and social services during the first year was 142,900 DKK (US $25,500). The hospital care until the first discharge, including acute care and rehabilitation, cost 101,600 Danish krones (DKK) (US $18,100), i.e., 71% of the total cost. Major resource items after discharge were nursing homes, readmissions, outpatient rehabilitation, and home help. The cost during the first year varied with a number of factors, with the most important being survival and degree of disability. Patients who survived the acute phase and who had severe disability (Barthel Activities of Daily Living [ADL] Index: 0–9) 7–10 days after admission had a total cost during the first year that was five times as high as patients with no disability (Barthel ADL Index: 20). Conclusion: Costs of health care and social services during the first year after a stroke vary considerably. Disability as measured with the Barthel ADL Index is a stronger predictor of costs than Scandinavian Stroke Scale scores and other clinical and demographic variables.
General behavior inventory identification of unipolar and bipolar affective conditions in a nonclinical university population.

Validated the General Behavior Inventory (GBI), revised to identify unipolar as well as bipolar affective conditions, in a nonclinical sample (n = 201) against naive, interview-derived diagnoses. For bipolar and unipolar conditions, respectively, the GBI had high positive (.94, .87) and negative (.99, .93) predictive power with the effect of prevalence considered, adequate sensitivity (.78, .76), high specificity (.99, .99), and adequate selection ratios for sampling of affective and nonaffective subjects from nonclinical populations for research purposes. The utility of the GBI in several different research contexts is discussed.
Endovascular management of RFA-induced hepatic arterial injury.

Radiofrequency ablation (RFA) is a widely accepted alternative treatment for unresectable primary and metastatic hepatic tumours with favourable survival and excellent local control rates. We describe the case of a patient with HCC who underwent ultrasound-guided RFA of a subcapsular lesion followed by vascular injury leading to haemoperitoneum which was managed by successful intra-arterial embolization of the bleeder.
Modeling Water Vapor and Clouds in an Idealized GCM

3 This paper introduces an idealized general circulation model (GCM) in which water vapor 4 and clouds are tracked as tracers, but are not allowed to affect circulation either through 5 latent heat release or cloud radiative effects. The cloud scheme includes an explicit treatment 6 of cloud microphysics and diagnoses cloud fraction from a prescribed sub-grid distribution 7 of total water. The model is capable of qualitatively capturing many large-scale features of 8 water vapor and cloud distributions outside of the boundary layer and deep tropics. The 9 subtropical dry zones, mid-latitude storm tracks and upper-tropospheric cirrus are simulated 10 reasonably well. The inclusion of cloud microphysics (namely rain re-evaporation) has a 11 significant effect of moistening the lower troposphere in this model. When being subjected 12 to a uniform fractional increase of saturated water vapor pressure, the model produces little 13 change in cloud fraction. A more realistic perturbation, which considers the non-linearity 14 of the Clausius-Clapeyron relation and spatial structure of CO2-induced warming, results in 15 a substantial reduction in the free-tropospheric cloud fraction. This is reconciled with an 16 increase of relative humidity by analyzing the probability distributions of both quantities. 17 The implications of these results and the utility of the idealized model for understanding 18 cloud feedback are discussed. 19
Do Private Equity Firms Pay for Synergies?

Stylized facts suggest that strategic acquirers can pay for synergies, while private equity (PE) firms cannot because of the missing operating fit with the portfolio company. However, if PE firms initiate buy-and-build strategies, there is potential for an operating fit between the portfolio firm and its add-on acquisitions. Thus, synergistic value could be priced in at entry. We analyze the pricing of 1,155 global PE buyouts and find strong support for a valuation effect from buy-and-build strategies. Our results indicate that PE sponsors pay a premium of up to 47% at entry when the portfolio company acquirers add-ons in the same industry within a two-year time window after the buyout. Consistent with bargaining power theory, the effect strengthens when the portfolio firm has acquisition experience, and when the PE sponsor faces pressure to invest because of unspent fund capital (referred to as “dry powder”) or deal competition. These findings remain robust after addressing alternative explanations, endogenous selection, and reverse causality. They have important implications for the literature on strategic versus financial bidders in takeovers.
Translational regulation of light-induced ribulose 1,5-bisphosphate carboxylase gene expression in amaranth

The regulation of the genes encoding the large and small subunits of ribulose 1,5-bisphosphate carboxylase was examined in amaranth cotyledons in response to changes in illumination. When dark-grown cotyledons were transferred into light, synthesis of the large- and small-subunit polypeptides was initiated very rapidly, before any increase in the levels of their corresponding mRNAs. Similarly, when light-grown cotyledons were transferred to total darkness, synthesis of the large- and small-subunit proteins was rapidly depressed without changes in mRNA levels for either subunit. In vitro translation or in vivo pulse-chase experiments indicated that these apparent changes in protein synthesis were not due to alterations in the functionality of the mRNAs or to protein turnover, respectively. These results, in combination with our previous studies, suggest that the expression of ribulose 1,5-bisphosphate carboxylase genes can be adjusted rapidly at the translational level and over a longer period through changes in mRNA accumulation.
