Streptococcus pneumoniae is a major cause of pneumonia, wherein infection of respiratory mucosa drives a robust influx of neutrophils. We have previously shown that S. pneumoniae infection of the respiratory epithelium induces the production of the 12-lipoxygenase (12-LOX)–dependent lipid inflammatory mediator hepoxilin A3, which promotes recruitment of neutrophils into the airways, tissue damage, and lethal septicemia. Pneumolysin (PLY), a member of the cholesterol-dependent cytolysin (CDC) family, is a major S. pneumoniae virulence factor that generates ∼25-nm diameter pores in eukaryotic membranes and promotes acute inflammation, tissue damage, and bacteremia. We show that a PLY-deficient S. pneumoniae mutant was impaired in triggering human neutrophil transepithelial migration in vitro. Ectopic production of PLY endowed the nonpathogenic Bacillus subtilis with the ability to trigger neutrophil recruitment across human-cultured monolayers. Purified PLY, several other CDC family members, and the α-toxin of Clostridium septicum, which generates pores with cross-sectional areas nearly 300 times smaller than CDCs, reproduced this robust neutrophil transmigration. PLY non–pore-forming point mutants that are trapped at various stages of pore assembly did not recruit neutrophils. PLY triggered neutrophil recruitment in a 12-LOX–dependent manner in vitro. Instillation of wild-type PLY but not inactive derivatives into the lungs of mice induced robust 12-LOX–dependent neutrophil migration into the airways, although residual inflammation induced by PLY in 12-LOX–deficient mice indicates that 12-LOX–independent pathways also contribute to PLY-triggered pulmonary inflammation. These data indicate that PLY is an important factor in promoting hepoxilin A3–dependent neutrophil recruitment across pulmonary epithelium in a pore-dependent fashion.

The African clawed frog, Xenopus laevis, is a model species for amphibians. Before metamorphosis, tadpoles do not efficiently express the single classical MHC class I (MHC-I) molecule Xela-UAA, but after metamorphosis, adults express this molecule in abundance. To elucidate the Ag-presenting mechanism of Xela-UAA, in this study, the Xela-UAA structure complex (pXela-UAAg) bound with a peptide from a synthetic random peptide library was determined. The amino acid homology between the Xela-UAA and MHC-I sequences of different species is <45%, and these differences are fully reflected in the three-dimensional structure of pXela-UAAg. Because of polymorphisms and interspecific differences in amino acid sequences, pXela-UAAg forms a distinct peptide-binding groove and presents a unique peptide profile. The most important feature of pXela-UAAg is the two–amino acid insertion in the α2-helical region, which forms a protrusion of ∼3.8 Å that is involved in TCR docking. Comparison of peptide–MHC-I complex (pMHC-I) structures showed that only four amino acids in β2-microglobulin that were bound to MHC-I are conserved in almost all jawed vertebrates, and the most unique feature in nonmammalian pMHC-I molecules is that the AB loop bound β2-microglobulin. Additionally, the binding distance between pMHC-I and CD8 molecules in nonmammals is different from that in mammals. These unique features of pXela-UAAg provide enhanced knowledge of T cell immunity and bridge the knowledge gap regarding the coevolutionary progression of the MHC-I complex from aquatic to terrestrial species.

Published: November 2019

Near infrared spectroscopy (NIR) is a technique widely used for the prediction of different chemical-physical features of wood. In this study, the technique was used to assess its potential to predict the mechanical characteristics of wood. Castanea sativa samples of three different European provenances were collected and laboratory tests were performed to assess the mechanical properties of wood samples. Modulus of elasticity (MOE), load-deflection curve and modulus of rupture (MOR) were calculated by using INSTRON machine with three points bending strength with elastic modulus, while density (D) was calculated according to the current standard. Samples were then analysed by means of NIR spectroscopy. The raw spectra were pre-processed and regression models were developed. Variables selection techniques were used to improve the model performance. In detail, MOE regression model returned an error of 696.01 MPa (R2=0.78). Instead, MOR and D prediction models must be further investigated on a wider number of samples considering the high variability in physical characteristics of chestnut wood. The results demonstrated the possibility to use NIR technique for the prediction of the mechanical properties of wood providing useful indications in evaluation-screening processes. Indeed, the presence of the principal wood compounds (cellulose, hemicellulose and lignin) and their influence in the characterisation of mechanical stress reactions were confirmed.

Psychological strengths: An interpretative phenomenological analysis of Muslim women leaders
Authors: Amla Fahrial , Buitendach Johanna H.
Published: November 2019

Orientation: The nature and representation of psychological strengths is an emerging area of positive psychology. Individual differences occur in strengths profiles between people, which may be attributed to educational, occupational, gender and cultural influences and can be qualitatively explored using interpretative phenomenological analysis (IPA). The application of strengths measurement is underway in South Africa, but locally developed, context-specific strengths taxonomies are currently lacking, as well as research linking psychological strengths and leadership. Muslim women in leadership deal with general gender-related leadership challenges as well as specific cultural and religious issues, and the application of psychological strengths may serve as enabling factors.Research purpose: This study aimed to explore and describe the psychological strengths demonstrated by a minority sub-population of South African women leaders in the workplace.Motivation for the study: Psychological strengths are linked to flourishing and well-being. Understanding their representation and their context of application can enhance both the academic literature and organisational practices surrounding them. A minority leadership group of Muslim women were appointed for this study, bearing in mind their particular leadership challenges and the enabling strengths they employ as a point of interest, as possible indicators for future strengths and leadership development initiatives.Research approach/design and method: Qualitative, semi-structured interviews were conducted with 15 Muslim women leaders from various employment industries who held senior management or leadership roles. IPA method was used for the analysis and interpretation of the results.Main findings: Interpretative phenomenological analysis of the interview data revealed a taxonomy of 28 psychological strengths, which were categorised as cognitive, emotional, interpersonal, values/motives or behavioural.Practical/managerial implications: The strengths may be focussed on for leadership development and it is recommended that the study should be replicated across various cultural groups to identify and develop the strengths that occur in the diversity of leaders within the South African work context.Contribution/value-add: This exploratory study contributes to the knowledge base of psychological strengths. It also highlights specific strengths to be considered when implementing leadership development programmes, particularly those for Muslim women in South African workplaces.

Другой взгляд на принцип максимума для задач оптимального управления с бесконечным горизонтом в экономике
Authors: Aseev Sergey Mironovich , Veliov Vladimir M.
Published: November 2019

В статье представлен недавно полученный авторами полный вариант принципа максимума Понтрягина для класса задач оптимального управления с бесконечным горизонтом, возникающих в экономике. Главной отличительной чертой данного результата является определение сопряженной переменной посредством явной формулы, аналогичной формуле Коши для решений линейных дифференциальных систем. В некоторых случаях эта формула влечет выполнение "стандартных" условий трансверсальности на бесконечности. Более того, она может использоваться в качестве их альтернативы. Приведены примеры, иллюстрирующие преимущества предлагаемого варианта принципа максимума. В частности, рассмотрено его применение к примеру Халкина, к модели оптимального экономического роста Рамсея, а также к базовой модели оптимальной эксплуатации невозобновляемого ресурса. Кроме того, дана экономическая интерпретация полученной характеризации сопряженной переменной.

Abstract. In a warming Arctic the increased occurrence of new
particle formation (NPF) is believed to originate from the declining ice
coverage during summertime. Understanding the physico-chemical properties of
newly formed particles, as well as mechanisms that control both particle
formation and growth in this pristine environment, is important for
interpreting aerosol–cloud interactions, to which the Arctic climate can be
highly sensitive. In this investigation, we present the analysis of NPF and
growth in the high summer Arctic. The measurements were made on-board
research vessel Polarstern during the PS106 Arctic expedition. Four
distinctive NPF and subsequent particle growth events were observed, during
which particle (diameter in a range 10–50 nm) number concentrations
increased from background values of approx. 40 up to 4000 cm−3. Based
on particle formation and growth rates, as well as hygroscopicity of
nucleation and the Aitken mode particles, we distinguished two different
types of NPF events. First, some NPF events were favored by negative ions,
resulting in more-hygroscopic nucleation mode particles and suggesting
sulfuric acid as a precursor gas. Second, other NPF events resulted in
less-hygroscopic particles, indicating the influence of organic vapors on
particle formation and growth. To test the climatic relevance of NPF and its
influence on the cloud condensation nuclei (CCN) budget in the Arctic, we
applied a zero-dimensional, adiabatic cloud parcel model. At an updraft
velocity of 0.1 m s−1, the particle number size distribution (PNSD)
generated during nucleation processes resulted in an increase in the CCN
number concentration by a factor of 2 to 5 compared to the background CCN
concentrations. This result was confirmed by the directly measured CCN
number concentrations. Although particles did not grow beyond 50 nm in
diameter and the activated fraction of 15–50 nm particles was on average
below 10 %, it could be shown that the sheer number of particles produced
by the nucleation process is enough to significantly influence the
background CCN number concentration. This implies that NPF can be an important
source of CCN in the Arctic. However, more studies should be conducted in
the future to understand mechanisms of NPF, sources of precursor gases and
condensable vapors, as well as the role of the aged nucleation mode
particles in Arctic cloud formation.

Published: November 2019

Abstract. Regional transport of air pollutants controlled by both emission sources and meteorological factors results in a complex source-receptor relationship of air pollution change. Wuhan, a metropolis in the Yangtze River Middle Basin (YRMB) of central China experienced heavy air pollution characterized by excessive PM2.5 concentrations reaching 471.1 μg m−3 in January 2016. In order to investigate the regional transport of PM2.5 over China and the meteorological impact on wintertime air pollution in the YRMB area, observational meteorological and other relevant environmental data from January 2016 were analyzed. Our analysis presented the noteworthy cases of heavy PM2.5 pollution in the YRMB area with the unique “non-stagnant” meteorological conditions of strong northerly winds, no temperature inversion and additional unstable structures in the atmospheric boundary layer. This unique set of conditions differed from the stagnant meteorological conditions characterized by near-surface weak winds, air temperature inversion, and stable structure in the boundary layer observed in heavy air pollution over most regions in China. The regional transport of PM2.5 over central-eastern China aggravated PM2.5 levels present in the YRMB area, thus demonstrating the source-receptor relationship between the originating air pollution regions in central-eastern China and the receiving YRMB regions. Furthermore, a backward trajectory simulation using FLEXPART-WRF to integrate the air pollutant emission inventory over China was used to explore the patterns of regional transport of PM2.5 governed by the strong northerly winds in the cold air activity of the East Asian winter monsoon over central-eastern China, which contributes markedly to the heavy PM2.5 pollution in the YRMB area. It was estimated that the regional transport of PM2.5 of non-local air pollutant emissions could contribute more than 65 % of the PM2.5 concentrations to the heavy air pollution in the YRMB region during the study period, revealing the importance of the regional transport of air pollutants over central-eastern China in the formation of heavy air pollution over the YRMB region.
Nitric oxide (NO) in the Bohai Sea and the Yellow Sea

Published: November 2019

Abstract. Nitric oxide (NO) is a short-lived compound of the
marine nitrogen cycle; however, our knowledge about its oceanic distribution
and turnover is rudimentary. Here we present the measurements of dissolved
NO in the surface and bottom layers at 75 stations in the Bohai Sea (BS) and
the Yellow Sea (YS) in June 2011. Moreover, NO photoproduction rates were
determined at 27 stations in both seas. The NO concentrations in the surface
and bottom layers were highly variable and ranged from below the limit of
detection (i.e., 32 pmol L−1) to 616 pmol L−1 in the surface layer
and 482 pmol L−1 in the bottom layer. There was no significant
difference (p>0.05) between the mean NO concentrations in the
surface (186±108 pmol L−1) and bottom (174±123 pmol L−1) layers. A decreasing trend of NO in bottom-layer concentrations
with salinity indicates a NO input by submarine groundwater discharge. NO in
the surface layer was supersaturated at all stations during both day and
night and therefore the BS and YS were a persistent source of NO to the
atmosphere at the time of our measurements. The average flux was about
4.5×10-16 mol cm−2 s−1 and the flux showed
significant positive relationship with the wind speed. The accumulation of
NO during daytime was a result of photochemical production, and
photoproduction rates were correlated to illuminance. The persistent
nighttime NO supersaturation pointed to an unidentified NO dark production.
NO sea-to-air flux densities were much lower than the NO photoproduction
rates. Therefore, we conclude that the bulk of the NO produced in the mixed
layer was rapidly consumed before its release to the atmosphere.
A novel rotor blade fatigue test setup with elliptical biaxial resonant excitation
Authors: Melcher David , Bätge Moritz , Neßlinger Sebastian
Published: November 2019

Abstract. The full-scale fatigue test of rotor blades is an important and complex part of the development of new wind turbines. It is often done for certification according to the current IEC (2014) and DNV GL AS (2015) standards. Typically, a new blade design is tested by separate uniaxial fatigue tests in both main directions of the blade, i.e. flapwise and lead-lag. These tests are time consuming and rather expensive due to a high number of required load cycles, up to 5 million. Therefore, it is important to run the test as efficiently as possible. During fatigue testing, the rotor blade is excited at or near its resonant frequency. The trend for new rotor blade designs is toward longer blades, leading to a significant drop in their natural frequencies, and a corresponding increase in test time. In order to reduce the total test time, a novel test method aims to combine the two consecutive uniaxial fatigue tests into one biaxial test. The biaxial test excites the blade in both directions at the same time and at the same frequency, resulting in an elliptical deflection path of the blade axis. Using elliptical loading, counting of damage equivalent load cycles is simplified in comparison to biaxial tests with multiple frequencies. In addition, the maximum loads in both main directions remain separated, while off axis loading is introduced. To achieve such a test, specific load elements need to be arranged to equalize the natural frequencies of the test setup for both test directions. This is accomplished by adding stiffness or inertial effects in a specific direction.
SemOutQuote: Using semantics for innovation offshore outsourcing management

Published: November 2019

In an increasingly globalised world, changes in organisations have also affected innovation processes. In the Information Technology (IT) domain, corporations are adopting outsourcing ad offshoring models for innovation, each time more carefully. The benefits of the combination of both practices, which demonstrate a decrease in corporate costs, indicate an incentive for the adoption of such practices as corporate strategies. In such a scenario, a two-sided challenge presents itself. In the first place, the companies contracting must establish selection measures and strategies for control of their suppliers. Secondly, the business offering outsourcing services must adopt appropriate measures to develop themselves as reliable partners in these types of relationships, a crucial aspect for both parties. The current work presents SemOutQuote, a semantics-based environment for the selection of stable partners for trustworthy innovation processes. The fusion of the capacities of interconnection and communication provided by the internet with the functionalities of the use of semantics represent a novel approach to the management of innovation in organisations

Defining the Integrated Performance Measurement Systems in Small and Medium Enterprises: An Advanced Model
Authors: Maria Grazia Pirozzi , Francesco Agliata , Danilo Tuccillo , Francesco Pirozzi
Published: November 2019

Purpose: The purpose of this paper is to propose an “Integrated Performance Measurement System” (PMS) addressing the measurement and management of the financial and non-financial performance and “Intellectual Capital” (IC) for the “Small and Medium Entreprises” (SMEs). The paper relies on the “Integrated New Model” (INM) by Pirozzi and Ferulano (2016) that deals with the same task applied to a specific sector. Thus, we propose the modification of the INM model to define a “Renewed and Advanced Model” called “INM*” as integrated PMS for SMEs.

Design/methodology approach: We used a qualitative method with an inductive and deductive approach to obtain an advanced model INM*. Thus, the SMEs characteristics are translated in our advanced INM* model according to the INM* structure and the IC framework. Moreover, we integrated in our proposed model INM* the “Strategic Management Accounting” (SMA) and the “Systems of Innovation” (SI) perspectives.

Findings: We proposed the advanced model INM* as integrated PMS. This is a model supporting entrepreneurial and innovative SME as well as a conceptual framework summarizing the interactions and the knowledge conversions that occur between the IC components within the innovation processes. Thus, the proposed model is a useful tool for SMEs organizations.

Originality/value: The renewed and advanced model INM* is useful in the academic and practical communities. It exhibits the advantages related to the innovative usage of a unique measurement system devoted to accomplish all the measurement tasks activated by SMEs. In addition, two other models are proposed and, in turn, are available for further research.
The Influence of Orthotics on Lower Limbs Biomechanics in CP
Authors: Krasowicz Krzysztof
Published: November 2019

The biomechanics of the human body has a direct impact on the quality of gait cycle. Patients with Cerebral Palsy (CP) often present incorrect gait patterns associated with structural deformities which directly influence the locomotor functions. The key to therapeutic success in those patients is the use of lower limb orthotics of the AFO type. This type of orthopedic devices should correct the skeletal deformities, optimize function and ensure high quality of daily use. Alignment of the lower limb supported by orthotics in all planes is crucial for changing the abnormal position of the ground reaction force (GRF) vector during a pathological gait cycle. GRFs produce an external moment of forces that causes extension or flexion of the lower limb in the sagittal plane. At the same time, those external conditions are balanced by an internal moment of forces generated by muscles. Some of the muscles are not directly attached to the joints but still support their function. This mechanism is called biomechanical coupling. This interesting relationship is also related to the inclination or reclination of the shank vertical angle (SVA) against the foot fixed on the ground in the midstance (MST) phase of gait. An optimal SVA angle is 7–12 degrees of tibial inclination. An insufficient or excessive SVA angle can be controlled by ankle foot orthotics (AFO). Those types of splints provide for better control of foot clearance during the swing phase and support distal stability of the lower limb chain during the stance phase of the gait cycle. An interdisciplinary approach is the key to success in the therapy of CP children who use lower limb orthotics. Nowadays, tridimensional gait analysis is an important tool for objective monitoring of those patients. It shows all kinematic and kinetic data recorded during gait with AFO and therefore helps to fine-tune orthotics used by CP patients.
Analysis and interpretation of air-conducted ocular vestibular-evoked myogenic potentials (AC-oVEMP) – our experience in healthy adults
Authors: Zwierzyńska Klaudyna , Lachowska Magdalena , Tataj Emanuel , Niemczyk Kazimierz
Published: November 2019

Background: Ocular vestibular-evoked myogenic potential (oVEMP) is one of recently introduced tests used to assess the function of the equilibrium system. It is still under research and no consensus has been reached yet. Aim: To analyze AC-oVEMP response parameters in subjects with no history of neurological or vestibular deficits. Material and Methods: The AC-oVEMPs collected from 50 subjects (100 ears) were analyzed in this prospective study for the response presence in the time domain, the latencies and amplitudes of the waves. Results: No statistically significant differences were observed between the right and left ear considering both N1 latency, and amplitude. Significant differences were noted when comparing the groups <40 yo vs ≥40 yo (shorter latencies and higher amplitudes were observed in subjects <40). Conclusions and Significance: This thorough AC-oVEMP analysis in a group of healthy volunteers facilitated the proposal of reference ranges with a simultaneous indication of age-related differences. Shorter oVEMP latencies and higher amplitudes were observed in subjects <40 yo, while in the subjects ≥40 yo the latencies were longer and the amplitudes lower.
Constructing Trade
Authors: Schram Sophie
Published: November 2019

This discourse analysis examines the trade policy interests of the province of Quebec during the CETA negotiations between Canada and the EU (2006–2014). The negotiation of the agreement’s chapters ‘Public Procurement’, ‘Foreign Direct Investment’ and ‘Agriculture’ from Quebec’s perspective documents that the provincial government drew upon existing repertoires of ideas in order to develop Quebec’s interests in a complex transatlantic setting and advance them skilfully. Canadian federalism as well as economic, political and cultural development discourses provided the framework for interpreting current and historical events, and for forging alliances to assert the province’s position. This study is based on the systematic quantitative analysis of parliamentary debates in Quebec and the qualitative evaluation of structured interviews with members of government, civil servants, business associations and NGOs.

Published: November 2019

A obra de Schenker convida a uma reflexão histórica sobre o apogeu do pensamento tonal e sua relação com as técnicas de contraponto. Embora prioritariamente associado ao pensamento harmônico funcional, o repertório tonal requer para sua interpretação uma compreensão dos processos contrapontísticos empregados para apresentar, manter e resolver as dissonâncias em vários níveis. Portanto, desconsiderar o contraponto presente nas obras do alto classicismo significa traduzir uma língua sem o conhecimento dos códigos apropriados e pode acarretar a perda da vitalidade original, improvisatória, deste repertório. Os artigos que examinaremos a seguir fazem parte do segundo volume do anuário Das Meisterwerk in der Musik, (1926) e serão acompanhados de uma reflexão histórica sobre a sonata K533 de Mozart.
Factors Affecting the Consumers Decision Behavior of Buying Green Products
Authors: AL-Ghaswyneh Odai Falah Mohammad
Published: November 2019

Objective: The study tackles the factors affecting customer’s behavior in making decisions regarding the purchase of eco-environmental-friendly-energy-saving green appliances in countries that moved to clean energy.

Methodology: The study follows the mixed-method approach by reviewing previous studies and analyzing collected data from study instruments that had been designed based on review results. The statistics were performed such as the mean and the standard deviation for all items in the questionnaire. ANOVA test was performed to determine the difference in the purchase decision for green products according to demographic characteristics. Exploratory Factor Analysis (EFA) was performed to improve the strength of the factors extracted from the questionnaire. Multiple regression analyses were performed to examine the relationship between Purchase Decision for green products and other factors. Finally, Confirmatory Factor analysis (CFA) was used for confirming the (EFA) result and the sample includes 232 customers of the electric appliances exhibits.

Results: Findings revealed that there is a strong positive correlation between the social, cultural, personal and psychological variables and the purchase decision taken by the consumer. Meanwhile, the psychological factors are the most effective in the decision-making process of purchase followed by the consumers’ place of residence (desert or mountainous). In addition, the social factor plays a critical role in making decisions about purchasing green products. However, cultural factors played a significant role in this regard. The study indicates that the least effective factors are personal factors, the energy consumption rate, and the monthly income.

Limitations: Study limitations include the targeted markets only that of rich-oil countries exclusively Saudi Arabia, and focused in the use of air conditioner machines. The time limitation is 2018-2019.

Practical implications: The study is useful as a roadmap for interested people in the field of energy and marketing inside oil countries and the era after oil utilization or within current decades of decreasing environmental effects done by burning oil and its’ driven materials.

Public Knowledge
Authors: Asher Michael
Published: November 2019

Writings by the conceptual artist Michael Asher—including notes, proposals, exhibition statements, and letters to curators and critics—most published here for the first time.

The California conceptual artist Michael Asher (1943–2012) was known for rigorous site specificity and pioneering institutional critique. His decades of teaching at CalArts influenced generations of artists. Much of Asher's artistic practice was devoted to creating works that had no lasting material presence and often responded to the material, social, or ideological context of a situation. Because most of Asher's artworks have ceased to exist, his writings about them have special significance. Public Knowledge collects writings by Asher about his work—including preliminary notes and ideas, project proposals, exhibition statements, and letters to curators and critics—most of which have never been previously published.

Asher gave few interviews, didn't write art criticism, and rarely published extensive accounts of his own work. Yet writing was central to his artistic practice, serving as a tool for working out ideas, negotiating institutional parameters, and describing thought processes. In these texts, he considers writing and documentation, discusses artistic practice, offers notes for gallery and museum talks, presents artist statements for exhibition-goers, describes individual works and their situational context, and reflects on teaching and art education. Among other things, Asher provides his definition of site specificity, addresses the function of art in public space, and analyzes the intersection of teaching art and institutional models of education. Readers will see an artist at work, formulating ethical and political strategies for making art in a situational world.
The Structure of Moral Revolutions
Authors: Baker Robert
Published: November 2019

A theoretical account of moral revolutions, illustrated by historical cases that include the criminalization and decriminalization of abortion and the patient rebellion against medical paternalism.

We live in an age of moral revolutions in which the once morally outrageous has become morally acceptable, and the formerly acceptable is now regarded as reprehensible. Attitudes toward same-sex love, for example, and the proper role of women, have undergone paradigm shifts over the last several decades. In this book, Robert Baker argues that these inversions are the product of moral revolutions that follow a pattern similar to that of the scientific revolutions analyzed by Thomas Kuhn in his influential book, The Structure of Scientific Revolutions.

After laying out the theoretical terrain, Baker develops his argument with examples of moral reversals from the recent and distant past. He describes the revolution, led by the utilitarian philosopher Jeremy Bentham, that transformed the postmortem dissection of human bodies from punitive desecration to civic virtue; the criminalization of abortion in the nineteenth century and its decriminalization in the twentieth century; and the invention of a new bioethics paradigm in the 1970s and 1980s, supporting a patient-led rebellion against medical paternalism. Finally, Baker reflects on moral relativism, arguing that the acceptance of “absolute” moral truths denies us the diversity of moral perspectives that permit us to alter our morality in response to changing environments.
Nihilism
Authors: Gertz Nolen
Published: November 2019

An examination of the meaning of meaninglessness: why it matters that nothing matters.

When someone is labeled a nihilist, it's not usually meant as a compliment. Most of us associate nihilism with destructiveness and violence. Nihilism means, literally, “an ideology of nothing. “ Is nihilism, then, believing in nothing? Or is it the belief that life is nothing? Or the belief that the beliefs we have amount to nothing? If we can learn to recognize the many varieties of nihilism, Nolen Gertz writes, then we can learn to distinguish what is meaningful from what is meaningless. In this addition to the MIT Press Essential Knowledge series, Gertz traces the history of nihilism in Western philosophy from Socrates through Hannah Arendt and Jean-Paul Sartre.

Although the term “nihilism” was first used by Friedrich Jacobi to criticize the philosophy of Immanuel Kant, Gertz shows that the concept can illuminate the thinking of Socrates, Descartes, and others. It is Nietzsche, however, who is most associated with nihilism, and Gertz focuses on Nietzsche's thought. Gertz goes on to consider what is not nihilism—pessimism, cynicism, and apathy—and why; he explores theories of nihilism, including those associated with Existentialism and Postmodernism; he considers nihilism as a way of understanding aspects of everyday life, calling on Adorno, Arendt, Marx, and prestige television, among other sources; and he reflects on the future of nihilism. We need to understand nihilism not only from an individual perspective, Gertz tells us, but also from a political one.
Beyond the Valley
Authors: Srinivasan Ramesh
Published: November 2019

How to repair the disconnect between designers and users, producers and consumers, and tech elites and the rest of us: toward a more democratic internet.

In this provocative book, Ramesh Srinivasan describes the internet as both an enabler of frictionless efficiency and a dirty tangle of politics, economics, and other inefficient, inharmonious human activities. We may love the immediacy of Google search results, the convenience of buying from Amazon, and the elegance and power of our Apple devices, but it's a one-way, top-down process. We're not asked for our input, or our opinions—only for our data. The internet is brought to us by wealthy technologists in Silicon Valley and China. It's time, Srinivasan argues, that we think in terms beyond the Valley.

Srinivasan focuses on the disconnection he sees between designers and users, producers and consumers, and tech elites and the rest of us. The recent Cambridge Analytica and Russian misinformation scandals exemplify the imbalance of a digital world that puts profits before inclusivity and democracy. In search of a more democratic internet, Srinivasan takes us to the mountains of Oaxaca, East and West Africa, China, Scandinavia, North America, and elsewhere, visiting the “design labs” of rural, low-income, and indigenous people around the world. He talks to a range of high-profile public figures—including Elizabeth Warren, David Axelrod, Eric Holder, Noam Chomsky, Lawrence Lessig, and the founders of Reddit, as well as community organizers, labor leaders, and human rights activists.. To make a better internet, Srinivasan says, we need a new ethic of diversity, openness, and inclusivity, empowering those now excluded from decisions about how technologies are designed, who profits from them, and who are surveilled and exploited by them.
Recovering Lost Species in the Modern Age
Authors: Jørgensen Dolly
Published: November 2019

A groundbreaking study of how emotions motivate attempts to counter species loss.

This groundbreaking book brings together environmental history and the history of emotions to examine the motivations behind species conservation actions. In Recovering Lost Species in the Modern Age, Dolly Jørgensen uses the environmental histories of reintroduction, rewilding, and resurrection to view the modern conservation paradigm of the recovery of nature as an emotionally charged practice. Jørgensen argues that the recovery of nature—identifying that something is lost and then going out to find it and bring it back—is a nostalgic practice that looks to a historical past and relies on the concept of belonging to justify future-oriented action. The recovery impulse depends on emotional responses to what is lost, particularly a longing for recovery that manifests itself in such emotions as guilt, hope, fear, and grief.

Jørgensen explains why emotional frameworks matter deeply—both for how people understand nature theoretically and how they interact with it physically. The identification of what belongs (the lost nature) and our longing (the emotional attachment to it) in the present will affect how environmental restoration practices are carried out in the future. A sustainable future will depend on questioning how and why belonging and longing factor into the choices we make about what to recover.
