Indigenous lead firms in rural regions: geography of global production networks revisited

ABSTRACT This paper examines regional distribution of indigenous lead firms in global production networks (GPNs). The paper triangulates unique evidence at the firm-level from a large innovation survey, extensive field interviews and detailed case studies in Czechia. The results indicate that lead firms are not predominantly urban species, as often assumed in the literature, but tend to be located to a surprisingly high extent in rural areas. Nevertheless, rural lead firms differ significantly from the urban ones in many respects. Urban regions turn out to be a seedbed for young, ambitious, close to the market and networked lead firms in new industries, which conforms to typical urbanization economics in action, whereas rural regions tend to harbor mature, established and relatively self-reliant lead firms with strong technical know-how in traditional industries, which build on location-specific resources and traditions. The results call for a more nuanced view on the coupling between GPNs and location advantages and more granular take on the regional dimension of innovation policy.
Damage Identification in Composites Based on Hilbert Energy Spectrum and Lamb Wave Tomography Algorithm

Lamb wave has already been known as one of the most prominent and promising tools in the field of nondestructive testing due to its wide range in detection and high sensitivity to damages. This paper put forward a method for damage location imaging on the basis of Hilbert Energy Spectrum and Lamb Wave Tomography. The damage localization imaging of composites were realized by simulation and experiment respectively. Firstly, the characteristics possessed by propagation of Lamb Wave before and after damages of composite plate were analyzed through the employment of simulation. The array of circular sensor was evenly arranged on the composite plate selected, and the each sensor acts as an actuator in turn for the purpose of generating Lamb Wave. In addition, other sensors were responsible for the collection of response signal. Finally, the damage factor was determined by the calculation on the difference between signals with or without damage by using Hilbert Energy Spectrum, and the location imaging of damage was achieved by adopting the probability imaging algorithm. It was shown by the experimental results that the maximum errors for imaging location of single damage and multiple damages were 5.00 mm and 9.22 mm, respectively. This method adopted avoids the extraction process of complex reflection signal, and thus it has great potential in damage location and identification conducted for composite materials.
Income Inequality and Status Symbols: The Case of Fine Wine Imports

Abstract This survey investigates the inequality-fine wine imports nexus. To this end, the study employs cointegration techniques to analyze two panel datasets, one of which will analyze data from 12 countries between 1871 and 2018, and another that analyzes data from 66 countries between 1995 and 2017. Estimations indicate that income inequality leads to more fine wine imports in the long run. Changes in income have only a short-term effect on fine wine imports. Nonlinear autoregressive distributed lag (NARDL) estimators reveal an asymmetric long-run relationship between income inequality and fine wine imports in the cases of Argentina and the United States.

Materiality in integrated and sustainability reporting: A paradigm shift?

This paper investigates the implementation of integrated reporting (IR) by Generali, one of the most important listed companies in Italy. The research questions we aim at answering are the following: Is the IR approach to materiality inherently different from the sustainability reporting (SR) approach? Does IR lead to the identification of different material topics than does SR? On the one hand, institutional theory suggests that IR and SR material topics are going to be significantly different because IR is mainly driven by a market logic, whereas SR is inspired by a stakeholder logic. On the other hand, organizational change theory predicts there will be some resistance to change by the organization, therefore leading to IR and SR topics being similar. In order to answer our research questions, we implement two empirical analyses. First, we propose and develop an innovative methodological approach on the basis of content analysis, which allows measuring the materiality of different issues under the IR approach. Second, we rely on evidence obtained through interviews, which suggests that IR and SR approaches to materiality are inherently different.

The Design of a European Unemployment (Re)Insurance Scheme: Lessons from US Experience

The American system of unemployment insurance (UI) is often cited as a model for potential European unemployment re-insurance schemes. While oversimplified comparisons are to be avoided, there are lessons Europe can learn from US federal-state relations regarding UI. We distinguish three aspects of the US system: first, in the 1930s the federal government was able to solve a collective action problem that impeded the development of state-level UI programs; second, during the 1950s Congress enacted a federal backstop for depleted state UI trust funds that are used to finance regular UI benefits; third, in the 1970s the federal government added an extra layer of UI to the state system, based on an intergovernmental co-financing of benefits which intensifies during crises and thus reinforces protection and stabilization where and when it is most needed. The second and third aspects now exercise European interest, which is about buttressing national systems with a supranational layer of insurance. The American experience shows that federal-state cooperation has overcome problems of collective action and enhanced stabilization. It proved to be of great importance in the Great Recession to effectively expand the protection of unemployed workers and to backstop state UI programs in a period of high and rising unemployment and thereby to contribute in a relevant way to the stabilization efforts of the Obama Administration. However, there are also some structural weaknesses in the American system. With a view to what might be developed in the EU, we identify two risks when an extra layer of unemployment protection is added at the supranational level. First, depending on the set-up of the system, federal-level financing of UI can lead to retrenchment of state-level efforts in terms of UI schemes and macroeconomic stabilization. Second, state-level retrenchment can lead to divergence between state UI programs. The US UI model is vulnerable to these two risks, although this may not be its main current challenge. Simultaneously, these risks – and the other problems besetting the American model – are not insurmountable. We draw both positive and cautionary lessons from the American experience. A lesson is that minimum requirements regarding generosity and coverage levels of UI programs are fundamental prerequisites for any supranational re-insurance.
Internationalism Under Platform Capitalism: Brexit and the Organisation of UK Fast Food Workers

In October 2018, a coalition of UK trade unions and civil society organisations called a strike across the UK’s fast food sector in support of a living wage, union recognition and the end to zero‐hour contracts in the sector. This paper takes the day of action—labelled the McStrike—as a starting point for an account of the place of the EU and Brexit in the campaign for fast food rights, as well as the contrasting political standpoints adopted by the different trade unions involved in the action. Brexit is used as a prism through which to analyse aspects of Britain’s contemporary food politics, especially those pertaining to freedom of movement, workplace organisation, and the role of EU legislation in protecting workers’ rights. In exploring the international dimensions of union organisation among the UK’s fast food workers, other, more conceptual considerations regarding the changing nature of public and private food consumption and the incorporation of food‐to‐go into the gig economy are also broached.
Recent development of automotive LiDAR technology, industry and trends

Autonomous driving technology is one of the core technologies for intelligent connected vehicles. For autonomous vehicles with L3 and higher-level capabilities, LiDAR is indispensable. Based on the substantial industry information of the sector and technical development, this paper systematically sorts through and analyzes a variety of LiDAR sensor technologies, the global automotive LiDAR industry ecosystem, major startups, the state-of-the-art products and so on. In addition, this paper provides in-depth research of the automotive LiDAR development trends and judgment on the prospects of automotive LiDAR integrated with the intelligent connectivity industry development trends. This paper considers that the LiDAR sensor has become a bottleneck hindering autonomous vehicles deployment, and predicts the future development paths of automotive LiDAR.
Youth perceptions of agriculture: influence of cognitive processes on participation in agripreneurship

ABSTRACT This article investigates the nature of youth perceptions and their influence on youth’s intentions of engaging in agripreneurship. The study findings reveal that the youth held positive economic perceptions of the agricultural sector. Along with the provision of secondary school agricultural education and a significant amount of financial support, these perceptions positively influenced their intentions to participate in agripreneurship. The findings affirm the need for improving awareness of the economic opportunities available in the agricultural sector. The study recommends that programmes that aim to encourage agripreneurship target both the socio-economic and cognitive limitations of youths.
Reversibele dementie bij gebruik van valpro?nezuur

A progressive dementia syndrome (DSM IV) with frontal-subcortical features developed in a 72-year-old woman during valproate therapy (Depakine). Discontinuation of valproate resulted in complete recovery. Drugs are a common cause of reversible dementia. The association of dementia with valproate therapy is rare. Features of a subcortical dementia are indicative of a reversible cause. In addition, the possible role of drugs should always be considered in patients with cognitive decline.
Disminuir el costo de las pensiones: una alternativa desde los mercados financieros de Colombia y México

Un elemento determinante para las finanzas públicas de los países latinoamericanos corresponde a la estimación del monto de las reservas actuariales correspondientes a las pensiones financiadas total o parcialmente por los gobiernos centrales, federales y regionales. En este artículo se propone una estrategia de gestión de portafolios pensionales, que considera la dinámica estocástica de los precios de los activos e integra una estrategia de cobertura dinámica que permite reducir el costo de las rentas vitalicias, aplicado a Colombia y México. En el primer caso, la estrategia de gestión del portafolio propuesta representa un ahorro promedio en el gasto público de 44.56%, equivalente a $3,803 millones de dólares aproximadamente, en el segundo caso, el ahorro es de 38.06%, equivalente a $16,631 millones de dólares aproximadamente. El planteamiento es relevante puesto que permitiría liberar recursos públicos invertidos en reservas actuariales pensionales o comprometidos para vigencias futuras, con los beneficios fiscales y principalmente sociales que ello conlleva, al dar soporte a una mayor cobertura de los sistemas de retiro o su utilización en la cobertura de otro tipo de necesidades de la población.
Overview of Emergency Department Visits in the United States, 2011

Emergency departments (EDs) provide a significant source of medical care in the United States, with over 131 million total ED visits occurring in 2011. Over the past decade, the increase in ED utilization has outpaced growth of the general population, despite a national decline in the total number of ED facilities. In 2009, approximately half of all hospital inpatient admissions originated in the ED. In particular, EDs were the primary portal of entry for hospital admission for uninsured and publicly insured patients (privately insured patients were more likely to be directly admitted to the hospital from a doctor’s office or clinic).

Clinical picture of orf in Northern California.

: Eighteen cases of orf are reported, six with multiple lesions and twelve with only one. Iridoform bullae were seen in every case, and untraumatized lesions healed without scar. The fingers and hands were involved in fourteen instances, the remainder occurring on the forearms, nose, forehead, and eyelid. Lack of systemic symptoms was usual, although several patients had regional adenopathy, malaise, and fever. Treatment was purely symptomatic, and x-ray therapy was not effective.
Towards Automated Parameter Optimisation of Machinery by Persisting Expert Knowledge

Commissioning of machines takes up a considerable share of time and money of the total cost of developing a machine. Our project aims at developing an approach to decrease the time needed to commission machines by automating parameter optimisation with the help of formalised expert knowledge. The approach will be developed on the Fused Deposition Modelling (FDM) process, which is an additive manufacturing technique. We pay particular attention to keeping the approach sufficiently abstract to be applied to machines from other domains to benefit its industrial application.
A Sensing Mode Reconfigurable Analog Front-End IC for Capacitive Touch and a-IGZO TFT-Based Active-Matrix Capacitive Fingerprint Sensors

In this paper, we propose a sensing mode reconfigurable analog front-end (AFE) IC for a capacitive touch sensor (CTS) and amorphous indium-gallium-zinc-oxide (a-IGZO) thin-film transistor (TFT)-based active-matrix capacitive fingerprint sensor (CFS). The CTS consists of the transmit and receive electrodes for enabling the mutual-capacitance (C<sub>M</sub>) sensing mode, which can detect the multi-touch. The CFS has the array of a-IGZO TFT and a sensing electrode for enabling the self-capacitance (C<sub>S</sub>) sensing mode to achieve the high sensitivity. In addition, it can reduce the number of sensing lines by adopting the active-matrix type structure to achieve the low-manufacturing cost. To sense the CTS and CFS, the proposed AFE IC is reconfigured to operate the C<sub>M</sub> and C<sub>S</sub> sensing modes, respectively. The proposed AFE IC was fabricated using a <inline-formula> <tex-math notation="LaTeX">$0.13~\mu \text{m}$ </tex-math></inline-formula> CMOS process technology with 20 V high-voltage devices, and demonstrated with a <inline-formula> <tex-math notation="LaTeX">$128\times 72\,\,32$ </tex-math></inline-formula>-inch CTS and a <inline-formula> <tex-math notation="LaTeX">$96\times 96\,\,0.27$ </tex-math></inline-formula>-inch CFS, which represents a pixel resolution of 500 pixel-per-inch. The proposed AFE IC achieves the signal-to-noise ratios of 47.8 dB and 25.0 dB for the CTS and CFS, respectively.
Social Media Affordances in Entry‐Level Employees’ Socialization: Employee Agency in the Management of Their Professional Impressions and Vulnerability During Early Stages of Socialization

This study examined how entry&#8208;level employees interacted with social media during three stages of organizational socialization. They navigated between four different media affordances (persistence, editability, visibility, and association) while experiencing them as both enabling and constraining in different socialization stages. Qualitative interview data analysis revealed during anticipatory socialization, job applicants realized visibility and persistence in relation to institutional and individualized socialization. During encounter, new employees managed personal and professional life boundaries carefully against the association and visibility affordances. Although some participants used both public and enterprise social media for obtaining job&#8208;related information and understanding coworkers and company culture, during metamorphosis, most interviewees adopted passive information seeking strategies and experienced a paradoxical tension between the enabling and constraining affordances of social media. Findings are discussed with regards to employees&#8217; exertion of agency in managing their professional impressions and coping with high levels of uncertainty and vulnerability during early stages of socialization.
The corporate sustainability index (CSI) and the impacts on indebtedness and risk perception

This study investigated whether the way firms fund themselves is affected by their participation in the Corporate Sustainability Index (CSI). As a complementary objective, we analyzed the relationship between the CSI and risk, based on signaling theory, which presents possible solutions to mitigate adverse selection problems caused by asymmetric information, used when there is a need to make decisions about investments in uncertain settings. We used a natural experiment based on a sample of 378 firms, divided into a treatment and a control group, with panel data and double fixed effect. The results indicate that the signaling of corporate ISSN 1519-7077 * Artigo apresentado no Congresso ANPCONT em 2010. Evimael Alves Teixeira, Valcemiro Nossa e Bruno Funchal R. Cont. Fin. – USP, Sao Paulo, v. 22, n. 55, p. 29-44, jan./fev. /mar./abr. 2011 30 social responsibility (CSR) was negatively related to indebtedness and risk when compared with firms that did not engage in such signaling. These results shed light on the relevance of sustainability indexes as a credible way for firms to indicate their commitment to CSR.
The Correlation between Serum Total Adiponectin and Hemoglobin in Type 2 Diabetic Patients without Microalbuminuria

Low serum total adiponectin is associated with a high incidence of type 2 diabetes or coronary artery disease in the general population. Paradoxically, serum total adiponectin is elevated in patients with chronic kidney disease (CKD), such as overt diabetic nephropathy. The current study aimed to investigate whether or not anemia to be dependently associated with serum level of total adiponectin in non-albuminuric male patients with type 2 diabetes . The study included 42 type 2 diabetic male patients. Anemia was dei¬ned as hemoglobin (Hb) below 14.0g/dL. All the patients were without microalbuminuria, to exclude diabetic nephropathy. The diabetic patients were divided into 2 groups according to the hemoglobin level in addition to 16 healthy control group. Serum total adiponectin levels were measured by a sandwich enzyme-linked immunosorbent assay. In all 42 patients with type 2 diabetes, serum total adiponectin levels were correlated positively with serum creatinine and age, whereas, negative correlations were found with Hb. A stepwise regression analysis demonstrated that among several signii¬cant variables, Hb had the strongest independent ini¬‚uence on total adiponectin (I² = -0.512, at P < 0.01). In conclusion, anemia could be associated with a marked elevation in serum total adiponectin levels of diabetic patients without a detectable nephropathy (-ve microalbuminuria). Key words: Type2 Diabetes, Adiponectin, Hemoglobin,Microalbuminuria.
Regulators of an ancient polyphenism evolved through episodic protein divergence and parallel gene radiations

Polyphenism is a form of developmental plasticity that transduces environmental cues into discontinuous, often disparate phenotypes. In some cases, polyphenism has been attributed to facilitating morphological diversification and even the evolution of novel traits. However, this process is predicated on the origins and evolutionary maintenance of genetic mechanisms that specify alternate developmental networks. When and how regulatory loci arise and change, specifically before and throughout the history of a polyphenism, is little understood. Here, we establish a phylogenetic and comparative molecular context for two dynamically evolving genes, eud-1 and seud-1, which regulate polyphenism in the nematode Pristionchus pacificus. This species is dimorphic in its adult feeding-structures, allowing individuals to become microbivores or facultative predators depending on the environment. Although polyphenism regulation is increasingly well understood in P. pacificus, the polyphenism is far older than this species and has diversified morphologically to enable an array of ecological functions across polyphenic lineages. To bring this taxonomic diversity into a comparative context, we reconstructed the histories of eud-1 and seud-1 relative to the origin and diversification of polyphenism, finding that homologues of both genes have undergone lineage-specific radiations across polyphenic taxa. Further, we detected signatures of episodic diversifying selection on eud-1, particularly in early diplogastrid lineages. Lastly, transgenic rescue experiments suggest that the gene's product has functionally diverged from its orthologue's in a non-polyphenic outgroup. In summary, we provide a comparative framework for the molecular components of a plasticity switch, enabling studies of how polyphenism, its regulation, and ultimately its targets evolve.
Moulding three-dimensional curved structures by selective heating

It is of interest to fabricate curved surfaces in three dimensions from homogeneous material in the form of flat sheets. The aim is not just to obtain a surface which has a desired intrinsic Riemannian metric, but to get the desired embedding in R3 up to translations and rotations. In this paper, we demonstrate three generic methods of moulding a flat sheet of thermo-responsive plastic by selective contraction induced by targeted heating. These methods do not involve any cutting and gluing, which is a property they share with origami. The first method is inspired by tailoring, which is the usual method for making garments out of plain pieces of cloth. Unlike usual tailoring, this method produces the desired embedding in R3. The second method just aims to bring about the desired new Riemannian metric via an appropriate pattern of local contractions, without directly controlling the embedding. The third method is based on triangulation, and seeks to induce the desired local distances. This results in getting the desired embedding in R3. The second and the third methods, and also the first method for the special case of surfaces of revolution, are algorithmic in nature. We explain these methods and show examples.
