Tau as a fluid biomarker of concussion and neurodegeneration
Authors: Hossain Iftakher , Blennow Kaj , Posti Jussi P , Zetterberg Henrik
Published: December 2022

Concussion is predominant among the vast number of traumatic brain injuries that occur worldwide. Difficulties in timely identification, whether concussion led to neuronal injury or not, diagnosis and the lack of prognostic tools for adequate management could lead this type of brain injury to progressive neurodegenerative diseases. Tau has been extensively studied in recent years, particularly in repetitive mild traumatic brain injuries and sports-related concussions. Tauopathies, the group of neurodegenerative diseases, have also been studied with advanced functional imaging. Nevertheless, neurodegenerative diseases, such as chronic traumatic encephalopathy, are still conclusively diagnosed at autopsy. Here, we discuss the diagnostic dilemma and the relationship between concussion and neurodegenerative diseases and review the literature on tau as a promising biomarker for concussion.

Authors: González--Betancourt Aurea Yahaira , González-Partida Eduardo , Carrillo-Chávez Alejandro , Iriondo Alexander
Published: December 2022

En este trabajo se pretende observar los cambios en los patrones de sedimentación y fauna de las Formaciones Eagle Ford e Indidura que afloran en el estado de Coahuila. Estas sucesiones sedimentarias se depositaron dentro del rango Cenomaniano-Turoniano en el interior de la cuenca de Sabinas y se componen de facies arcillosas, carbonatadas, bioclásticas y arenosas. Fueron descritas nueve microfacies (Mf), la Mf-1 mudstone; la Mf-2 lutita y wackestone con foraminíferos oportunistas; la Mf-3 wackestone de foraminíferos especialistas, la Mf-4 wackestone y packstone de radiolarios; la Mf-5 wackestone y packstone con filamentos; la Mf-6 grainstone peloidal; la Mf-7 grainstone bioclástico; la Mf-8 calcarenitas; y la Mf-9 tobas volcánicas intercaladas en la sucesión. La ocurrencia del evento oceánico anóxico OAE-2 (OAE del inglés: Oceanic Anoxic Event) está presente dentro de la sucesión sedimentaria, indicado por los depósitos de lutitas negras ricas en materia orgánica, la muerte masiva de foraminíferos planctónicos, abundantes filamentos, cristales de pirita y las concentraciones elevadas de elementos redox como el V, Mo y Mn. Sin embargo, las condiciones de depósito presentan una variación en la concentración de oxígeno, micronutrientes y materia orgánica a lo largo de la paleogeografía. Elementos como Ni y Zn en las microfacies 1, 2, 3 y 4 evidencian una alta productividad, la cual está asociada a la presencia de organismos planctónicos y/o radiolarios. Otros elementos químicos como el Al, K y Zr muestran un incremento en el aporte de material detrítico dentro de la cuenca asociado a las microfacies arcillosas y arenosas. El contenido de materia orgánica es más elevado de la microfacies 2 a la 5 y además se considera de origen autóctono. La variación en las condiciones óxico-anóxicas es notoria gracias a la relación de foraminíferos planctónicos-bentónicos y las relaciones geoquímicas entre los elementos de Mo, Va, Ni y S. En la Formación Indidura las edades de U–Pb en granos de circón procedentes de capas de tobas restringen el depósito entre 98.2 ± 0.9 Ma a los 91.7 ± 0.8 Ma, es decir Cenomaniano- Turoniano, aunque la presencia de Praeglobotruncana a la base restringe el depósito al Cenomaniano tardío- Turoniano. Mientras que la edad de la Formación Eagle Ford está indicada por los géneros Rotalipora cushmani, Hedbergella y Helveglobotruncana helvética del Cenomaniano y Turoniano.
A new coral family and three new genera from the Lower Cretaceous of Puebla and Sonora (Scleractinia; Mexico)
Authors: Löser Hannes
Published: December 2022

Solitary corals currently assigned to the genus Plesiosmilia are common elements in Late Jurassic to Early Cretaceous coral faunas. The genus itself is poorly defined and its systematic position is questionable. Moreover, examination of type material has shown that the genus lumps corals of different morphologies. Here, one common coral type is separated in a new solitary coral genus as well as two new phaceloid coral genera with a comparable morphology. The three new and another three existing genera are collected in a new family. The newly described material comes from the Upper Valanginian-Lower Hauterivian of San Juan Raya (Puebla) and the Lower Albian of Rayón (Sonora, both Mexico).
New Trigonometrically Method for Solving Non-Linear Transcendental Equations
Authors: S Pavithra , T Priyadharshini.
Published: December 2022

Abstract: The transcendental equations' non-zero positive real roots can be found using a new approach presented in this research. The proposed approach is based on the union of the Newton-Raphson method and the inverse tan(x) function. To ensure the method's applicability, it is implemented in MATLAB and applied to various issues. The suggested approach is evaluated on a variety of numerical instances, the results show that our approaches are superior and more efficient than widely used methods. For both the new proposed method and the currently accessible existing methods, error calculations have been made. When compared to well-known procedures, the mistakes were quickly minimised, and the genuine root was discovered in fewer repetitions. The proposed method's convergence is studied, and it is demonstrated that it reduces to the quadratic convergent Newton-Raphson method. This method will also assist in the production of a non-zero real root of a specified nonlinear equation in the commercial software (transcendental, algebraic, and exponential).

Abstract: In this present time, authentication is the way of giving persons access to system object based on user's uniqueness. If the codes match, the process will be succeed and user will get the consent to access the system. Text based password scheme follows the guidelines such as at least 8 characters long, should combine upper-case and lower-case and digit. user have problem to remember their complicated password over time due to the limitation of human brain, user tend to forget about their password. User tend to use the same password for all type of account. So if one account is hacked, the possibility for other account to be hack is a high. Graphical password can be used as alternative to solve the issue related to the text-based authentication based on the fact that humans can tend to remember pictures batter then text. Now a day’s many computer system, Network and internet based environment are trying to use of graphical authentication technique in this paper we make a survey of the basic authentication and its technique and also presents a comprehensive study of graphical password authentication method and graphical password system.

Apego al lugar y percepción del riesgo volcánico en personas mayores de Ñuble, Chile
Authors: Sandoval-Díaz José Sebastián , Monsalves-Peña Saron Rosa , Vejar-Valle Viviana , Bravo-Ferretti Cristobal
Published: December 2022

Chile has a high degree of exposure and susceptibility to disaster risk scenarios, and it is among the top five countries in the world regarding active volcanoes. Meanwhile, sustained population aging is making the older population vulnerable to potential socio-natural disasters. This article, using these concepts, seeks to understand the relationship between place attachment and the perception of volcanic risk among the older population, focusing on older adults residing in the hazard zone of the Nevados de Chillán volcanic complex in the Ñuble Region in southern Chile. Using a phenomenological qualitative case design, 15 semi-structured interviews and a focus group were applied, with the analysis carried out based on grounded theory. The results indicate that the older population has a low perception of volcanic risk, entailing i) the minimization of the surrounding natural hazards, ii) informal knowledge based on previous experiences, and iii) ignorance of the natural risk characteristics and their negative consequences. On the other hand, it is seen that place attachment and social vulnerability act not only as contextual barriers to accepting the volcanic risk but also lead to a lack of engagement, acquisition, and deployment of individual and collective coping mechanisms. In conclusion, the authors outline the importance of including “aging in place” and the active agency of the older population in socio-natural disaster risk planning and local management processes.
Ciclos de estabilidad, cambios y variables lentas-rápidas en el paisaje del Área Metropolitana de Concepción a partir de estudios de sistemas socio ecológicos: un análisis exploratorio
Authors: Ojeda-Leal Carolina Grace , Bergamini Ladrón de Guevara Kay Joaquín
Published: December 2022

Landscapes can maximize their strengths in moments of stability by deeply developing their character and, thus, managing the pressures or disturbances behind slow and fast changes in the Socio-Ecological Systems (SES) to avoid their transformation. Fast variables explain short-term changes and violent rupture processes in stability/change cycles for natural disaster issues. On the other hand, slow variables explain long-term changes and more complex processes in stability/change cycles. The work below focused on studying the Concepción Metropolitan Area (AMC, in Spanish), Chile, which has undergone relevant changes throughout its history but has not been studied as an SES using its slow and fast variables. An exploratory literary review of 150 articles was made in scientific databases without using scientific support software, considering "Concepción" and "Concepción Metropolitan Area" as keywords. The main results highlight short-term phenomena cycles -fast variables- with a major impact, exemplified in natural disasters (earthquakes, tsunamis, floods, fires, and drought), changes in urban planning (urban plans and hygienism), as well as long-term phenomena -slow variables-, with more notable impacts in certain key areas, namely political (conquest and war between indigenous/Spanish/Chilean peoples), economic (boom/bust of business cycles) and environmental (wetland intervention, creation of different protection laws).
Design of Influent Distribution System in Domestic Wastewater Treatment Units
Authors: Macías Astrid L. , Rodríguez Diana C. , Molina Francisco J.
Published: December 2022

The efficient treatment of domestic wastewater is associated with good operational practices in wastewater treatment plants (WWTP) and the proper design of each treatment unit, which ensures the correct hydraulic performance of each WWTP. For this reason, the objective of this article was to study the design of the multiple influent distribution systems of a high-rate primary sedimentary, a UASB (Upflow Anaerobic Sludge Blanket) reactor, and an up-flow anaerobic filter (FAFA) in the WWTPs of the municipalities of San Carlos and San Roque, and in the township of Santiago, respectively, located in Antioquia-Colombia. For this purpose, the methodology proposed by Hudson in 1981 was used to evaluate the performance of the current design and, subsequently, a pre-dimensioning was carried out to distribute the flow uniformly, to have velocities within the ranges recommended by the literature, and to obtain the total head loss generated by the distribution manifold in each treatment unit evaluated. It was found that the existing design is not efficient and that the new pre-dimensioning ensures homogeneous flow distribution and provides velocities that contribute positively to the treatment process. The study concludes that the smaller the number of orifices and the larger the pipe diameter, the more uniform the flow distribution, and that the total head loss depends on both the velocity head and the head loss coefficient. The diameter of the orifice was the predominant parameter to control the inlet velocity of the treatment units.

Published: December 2022

Image representation is one of the major aspects of automatic classification algorithms. In this paper, different feature extraction techniques have been utilized to represent medical X-ray images. They are categorized into two groups; (i) low-level image representation such as Gray Level Co-occurrence Matrix(GLCM), Canny Edge Operator, Local Binary Pattern(LBP) , pixel value, and (ii) local patch-based image representation such as Bag of Words (BoW). These features have been exploited in different algorithms for automatic classification of medical Xray images. We then analyzed the classification performance obtained with regard to the image representation techniques used. These experiments were evaluated on ImageCLEF 2007 database consists of 11000 medical X-ray images with 116 classes. Experimental results showed the classification performance obtained by exploiting LBP and BoW outperformed the other algorithms with respect to the image representation techniques used.
Greedy Interaction Elements Coverage Analysis for AI-Based T-Way Strategies
Authors: Al-Sewari AbdulRahman A. , Khamis Norazlina , Zamli Kamal Z.
Published: December 2022

Recently, many researchers have started to adopt Artificial Intelligence AI-based strategies for t-way testing. Here, each interaction is covered at most once whenever possible. In many AI-based strategies, sampling for the most optimal test cases is given utmost priority, but measuring of the interaction coverage metric per test case is often neglected. In the situation where not all test cases can be executed due to constraints on project deadline, the availability of interaction coverage metric per test case can be a useful indicator on how greedy each AI-based strategy of interests is. In this manner, test engineers can make informed decision on the selection of suitable strategies for use. In this paper, this study presents a systematic analysis of existing AIbased strategies including that of Hill Climbing HC, Simulated Annealing SA, Tabu Search TS, Great Flood GF, Particle Swarm Optimization PSTG and Harmonic Search Strategy HSS as far as its rate of coverage per test case is concerned. In doing so, this paper demonstrates that HSS, in most cases, gives competitive interaction coverage rate as compared to competing AI-based strategies but with less number of iterations.
Conhecimento ancestral e conhecimento científico

Published: December 2022

Este artigo reúne elementos de um trabalho de pesquisa sobre o conhecimento ancestral identificado na comunidade Páez de Valle del Cauca e problematiza a ausência de diálogo com o conhecimento científico que é ensinado na escola. Para o desenvolvimento deste estudo é assumida uma metodologia qualitativa com abordagem descritiva, projetando instrumentos de coleta de informações, como a entrevista semiestruturada. Além disso, a comparação de duas visões sobre a origem da vida, da comunidade Nasa Paez e da ciência. Os resultados da investigação destacam aspectos significativos da visão de mundo sobre a natureza e o território ao redor de moorland, lagoas e plantas da região e contrastam com as visões que são ensinadas nas aulas de ciências. Identificou-se uma ruptura entre comunidade, conhecimento ancestral e ensino de ciências naturais, de forma que o conhecimento ancestral é apresentado como folclórico deixando-o de lado nos processos educativos. Conclui-se sobre a necessidade de novas abordagens que estabeleçam um diálogo entre saberes e que permitam a comunicação entre o conhecimento ancestral e o conhecimento científico.
Leadless versus Transvenous Single-Chamber Ventricular Pacemakers: Three Year Follow-Up of the Micra CED Study
Authors: Crossley George , Piccini Jonathan , Longacre Colleen , Higuera Lucas , Stromberg Kurt , El-Chami Mikhael
Published: December 2022

Background: The Micra Coverage with Evidence Development (CED)
Study is a novel comparative analysis of Micra (leadless VVI) and
transvenous single-chamber ventricular pacemakers (transvenous VVI)
using administrative claims data. Objective: To compare chronic
complications, device reinterventions, heart failure hospitalizations,
and all-cause mortality after 3 years of follow-up.  Methods:
U.S. Medicare claims data linked to manufacturer device registration
information were used to identify Medicare beneficiaries with a de
novo implant of either a Micra VR leadless VVI or transvenous VVI
pacemaker from March 9, 2017-December 31, 2018. Unadjusted and
propensity score overlap-weight adjusted Fine-Gray competing risk models
were used to compare outcomes at 3 years.   Results: Leadless
VVI patients (N=6,219) had a 32% lower rate of chronic complications
and a 41% lower rate of reintervention compared with transvenous VVI
patients (N=10,212) (chronic complication hazard ratio [HR] 0.68;
95% CI, 0.59-0.78; reintervention HR 0.59; 95% CI 0.44-0.78).
Infections rates were significantly lower among patients with a leadless
VVI (<0.2% versus 0.7%, P<0.0001). Patients with a
leadless VVI also had slightly lower rates of heart failure
hospitalization (HR 0.90; 95% CI 0.84-0.97). There was no difference in
the adjusted 3-year all-cause mortality rate (HR 0.97; 95% CI,
0.92-1.03).  Conclusion: This nationwide comparative evaluation
of leadless VVI versus transvenous VVI de novo pacemaker implants
demonstrated that the leadless group had significantly fewer
complications, reinterventions, heart failure hospitalizations, and
infections than the transvenous group at 3 years, confirming that the
previously reported shorter-term advantages associated with leadless
pacing persist and continue to accrue in the medium-to-long-term.
Kids and COVID-19: they are winning with their immunity
Authors: Bayazed Husham
Published: December 2022

Background: As the COVID-19 pandemic evolves, many pediatricians and
infants’ parents have been left with renewed questions about the
consequences of infection on children and steps to be taken if their
child has symptoms of, or tests positive for, COVID-19. Methods &
Results: Literature reviews and recent studies revealed that children
are better than adults at combating SARS –CoV‑2. There was conflicting
evidence on age-related differences in ACE2 expression in the nose and
lungs. However, measurements of SARS-CoV-2 viral load’ have shown no
clear difference. Strikingly, cross-reactive antibodies from previous
exposure to coronavirus common cold do not offer any special protection
in both children and adults. The kid’s immune response against SARS‑
CoV-2 infection is initiated with low immunological tone to prevent
overactive immunity and is characterized by rapid lung damage repair in
contrast to stormy waves in adults. Conclusion: One of the few silver
linings of the COVID-19 pandemic is that children are relatively spared
and wining with their immunity.

Controlling the process of CHO cell fed-batch culture is critical for
biologics quality control. However, the biological complexity of cells
has hampered the reliable process understanding for industrial
manufacturing. In this study, a workflow was developed for the
consistency monitoring and biochemical marker identification of the
commercial-scale CHO cell culture process through H
NMR assisted with multivariate data analysis (MVDA). Firstly, a total of
63 metabolites were identified in this study object in
H NMR spectra of the CHO cell-free supernatants.
Secondly, multivariate statistical process control (MSPC) charts were
used to evaluate process consistency. According to MSPC charts, the
batch-to-batch quality consistency was high, indicating the CHO cell
culture process at the commercial scale was well-controlled. Then, the
biochemical marker identification in the cell logarithmic expansion,
stable growth, and decline phases were provided through orthogonal
partial least square discriminant analysis (OPLS-DA) based S-line plots.
L-glutamine, pyroglutamic acid, 4-hydroxyproline, choline, glucose,
lactate, alanine, and proline were determined as biochemical markers of
the logarithmic growth phase. Isoleucine, leucine, valine, acetate, and
alanine were determined as biochemical markers of the stable growth
phase. Acetate, glycine, glycerin, and gluconic acid were identified as
biochemical markers of the cell decline phase. The workflow proposed in
this study demonstrates that the combination of MVDA tools and
H NMR technology is highly appealing to the research
of the biomanufacturing process, and applies well to provide critical
guidance in future work on consistency evaluation and biochemical marker
monitoring of the production of other biologics.
Dynamic Frequent Trajectory Mining Algorithm Based on Confidence of Suffix Subsequence
Authors: He Fan , Liu mandan , Zhong Chao
Published: December 2022

With the popularization of smart devices and the continuous development
of wireless communication technology, a large amount of trajectory data
is recorded in wireless networks, and frequent item mining for
trajectory data has become a research hotspot. In order to rapid update
frequent trajectory set when new data is added to the original
trajectory database, and to solve the problem that trajectory database
occupies a large amount of storage space, we propose a new dynamic
PrefixSpan algorithm based on the confidence of suffix subsequence
(CSS-PrefixSpan). This algorithm makes full use of the information of
the frequent trajectory set and estimates the support of infrequent
trajectory by using the confidence of infrequent trajectory suffix
subsequence. When incremental trajectory data is added to the original
trajectory database, CSS-PrefixSpan can dynamically update frequent
trajectory set and no longer need to store the original trajectory data
after mining frequent trajectories. Through two trajectory dataset
mining experiments, the accuracy of the support estimation and the
effectiveness of proposed algorithm are verified.

Published: December 2022

Soil microbes are key players in wetland ecosystems. The biogeography of
bacterial and fungal communities and their underlying mechanisms for
generating and maintaining lakeshore wetlands are important in microbial
ecology but remain unclear. Here we investigated the biogeographical
patterns and the factors shaping bacterial and fungal communities in
lakeshore wetland soils at a regional scale in northern China. Our
results revealed that the diversity of soil bacterial and fungal
communities in lakeshore wetlands had significant geographical
distribution patterns in both longitude and latitude gradients; and
notably the geographical distribution pattern of α-diversity is mainly
manifested in species richness. Climate, edaphic properties, and plant
diversity together determined the geographical distribution patterns of
bacterial and fungal community diversity, contributing 66.05% and
49.66% of the diversity variation, respectively. As droughts intensify,
the assembly of bacterial communities is gradually dominated by
deterministic processes dominated of habitat filtration, while fungal
communities are dominated by random processes of species dispersal.
Structural equation modelling revealed that the differences in
temperature and precipitation originating from geographical distances
directly modulated the geographical distribution of fungal community
diversity, while bacteria were indirectly regulated by influences of
local soils and plants. Our findings highlight that different
sensitivity of soil bacteria and fungi to climate change and different
responses to soil communities in lakeshore wetlands may have profound
implications for the stability and functioning of wetland ecosystems.

Problemática: el artículo trata de los riesgos financieros que afrontan las mipymes que desarrollan actividades comerciales en la ciudad de Villavicencio, en el departamento del Meta. El horizonte temporal de análisis es el de los años 2017-2019. Objetivos: analizar las condiciones en que las mipymes están enfrentando los posibles riesgos financieros derivados de su operación comercial. Realizar una revisión de bases de datos relacionadas con la actividad comercial de las mipymes objeto de estudio, determinar sus condiciones de operación, así como su relación con los posibles riesgos financieros, y determinar relaciones entre los riesgos de mercado, liquidez, crédito y operación, en el período de análisis. Materiales y métodos: la investigación es de tipo descriptiva y exploratoria. Su enfoque es cuantitativo. El estudio se basa, en primer lugar, en el análisis de fuentes secundarias con base en los datos de las cámaras de comercio; en segundo lugar, en la aplicación de una encuesta con 19 ítems a una muestra aleatoria de 31 mipymes en la ciudad de Villavicencio. Resultados y discusión: en el período de análisis, las condiciones económicas de las mipymes encuestadas presentan una situación de equilibrio de mercado, la cual les permitió contar con la liquidez necesaria para un manejo adecuado de sus fuentes de autofinanciamiento y crédito externo en pro del desarrollo de sus operaciones comerciales. Conclusiones: los riesgos de mercado (relación de clientes y proveedores) representan la posible aparición de riesgos de liquidez (mora en cobros a clientes y morosidad en pagos a proveedores), que conduce o no a enfrentar riesgos de crédito (accesos a endeudamiento externo). De este mecanismo secuencia depende la aparición de riesgos de operación para las mipymes de actividad comercial en Villavicencio. Contribución: la investigación se direccionó hacia el mejoramiento continuo y la perdurabilidad de las micro, pequeñas y medianas empresas, fundamentalmente las inscritas en actividades comerciales a nivel de las operaciones en ciudades de características de mercados similares a Villavicencio.
On the Seidel integral graphs which belong to the class αKa,a ∪ βKb,b

We say that a simple graph G is Seidel integral if its Seidel spectrum
consists entirely of integers. If ?Ka,a ? ?Kb,b is Seidel integral, we show
that it belongs the class of Seidel integral graphs [kt/? x0 + mt/?z]Ka,a ?
[kt/? y0 + a/?z]nKb,b, where (i) a = (t+?n)k+?m and b = ?m; (ii) t, k, ?,m,
n ? N such that (m, n) = 1, (n, t) = 1 and (?, t) = 1; (iii) ? = (a,mt) such
that ? | kt; (iv) (x0, y0) is a particular solution of the linear
Diophantine equation ax ? (mt)y = ? and (v) z ? z0 where z0 is the least
integer such that (kt/? x0 + mt/?z0)? 1 and (kt/? y0 + a/?z0) ? 1. In
particular, we demonstrate that ?Ka ? ?Kb is integral in respect to its
ordinary adjacency matrix if and only if ?Ka,a ? ?Kb,b is Seidel integral.

The polar derivative of a polynomial P(z) of degree n with respect to a
complex number ? is a polynomial nP(z) + (??z)P?(z) of degree at most n?1
and is denoted by D?P(z). We consider the class of polynomials P(z) = a0 + ?n
v=? avzv, ? ? 1, of degree n such that P(z) ?0 in |z| < k, k ? 1 and
establish some upper bound estimates for the maximum modulus of D?P(z) on the
unit disk by involving some of the coefficients of P(z). The obtained
results refine and generalize some well known polynomial inequalities.

Published: December 2022

Introduction. Around 2% of all cutaneous neoplasms arise in the scalp and can be classified as either primary or metastatic. The intracranial extension is rare in cutaneous malignancies but can generally occur if left un-treated. Squamous cell carcinoma (SCC) is the second most common type of nonmelanoma skin cancer after basal cell carcinoma. About 3?8% of SCCs are located on the scalp and can cause skull and dural invasion in rare cases. Case report. A 49-year-old male patient presented with a large and painful lesion in the parietooccipital region of the head. Magnetic resonance imaging (MRI) revealed a large inhomogeneous, necrotic lesion with infiltration of the underlying skull and dura. The patient underwent surgical removal of the tumor with excision of invaded skin, bone, and dura with a safety margin of 1 cm, followed by custom prefabricated 3D-printed cranioplasty with polymethylmetacrilate. Pathohistological analysis revealed invasive SCC with immunohistochemistry staining revealing CK5/6 and CK7 positivity. Conclusion. Some cases of scalp SCCs can cause invasion of the underlying skull and dura if left untreated. Imaging modalities like computed tomography (CT) and MRI play a crucial role in evaluating the degree of neo-plastic extension and potential calvarial and dural invasion, thus being of significant importance in preoperative planning and management.
The Gestalt Whitehead
Authors: Desmet Ronny
Published: December 2022

The aim of the first part of this article is to highlight some of the historical roots of the affinities of Whitehead’s philosophy with Gestalt psychology by identifying a number of physicists as well as philosopher-psychologists playing a relevant role in both the genesis of Whitehead’s thought and that of Gestalt psychology. The article goes beyond identifying Faraday and Maxwell as well as James and Bergson as relevant in this respect. It also focuses on others who have influenced Whitehead: Lorentz as well as Lotze and Brentano, Ward and Stout. The aim of the second part of this article is to introduce three of Whitehead’s key ideas by means of a number of simple Gestalt experiments: his idea of what mathematics is all about, his idea of what is wrong with Einstein’s interpretation of special and general relativity, and his idea of the role of recognition in the subjective form of feeling.
Process Ethics and Business: Applying Process Thought to Enact Critiques of Mind/Body Dualism in Organizations
Authors: Macklin Rob , Mathison Karin , Dibben Mark
Published: December 2022

The study of organizational ethics continues to be the focus of significant academic attention, however it is a discourse that remains largely informed by a form of morality that is perhaps best described as ordered and cognitive. Traditional approaches to questions of organizational ethics emphasize a fundamentally static view of organizations and the people within them, reinforcing notions of mind/body dualism and reifying ethics as an outcome of human agency, choice, and deliberate intention (see MacKay and Chia). We challenge this approach and instead argue in favor of ethics research that adopts an ontology grounded in process metaphysics. Escaping the confines of Cartesian dualism, we reconceptualize organizational ethics as something that is in fact not held constant, is not a static termination point or an outcome of events, but is rather an input into the continually reconstituting context of the organization over time (see Langley, et al). The process ethics we articulate provides a grounding for moral critique in diverse communities that is not undermined by relativism. Moreover, it provides guidance to managers and employees facing moral problems without forcing them to face a tyranny of principles. We consider how a process ethics would be enacted in organizations through managerial decision-making and in the treatment of employees.
Transcendent Creativity
Authors: Ford Lewis S.
Published: December 2022

Immanent creativity activates the concrescence of each actual occasion. Transcendent creativity lies beyond all occasions and is the source of their creativity. God, here conceived as purely temporal, is the subjectivity of transcendent creativity.
THE DEPTHS OF COMPASSION
Authors: Buchanan John H.
Published: December 2022

Some notion of compassion must play a central role in conceiving of a true process psychology. In Whitehead’s metaphysics, "feeling the feelings of others" is how reality itself is constructed. By placing primitive feeling at the heart of perception, experience, and the nature of reality, process philosophy helps psychology envision compassion as a way of connecting directly to the depths of others, of nature, and of ourselves. This paper focuses on some deeper experiences of compassion, as elucidated by transpersonal psychology, and how these spiritual experiences might be accessed and utilized in these challenging times.
"A Dialectic of Contrasts": Robert Duncan and Denise Levertov’s Ecological Writing
Authors: Hoeynck Joshua S.
Published: December 2022

"A Dialectic of Contrasts" details how the mid-twentieth century American poets Robert Duncan and Denise Levertov employed their understanding of Whitehead’s notion of "contrast" to imagine poems closely linked to ecology and cosmology. Exploring the references to Whitehead’s heterogeneous dialectic of contrasts in the Duncan/Levertov correspondence, the article displays the forcible role Whitehead’s thought played in directing the two poets to a linguistic-organic poetics invested in nonhuman agency.
A Response to G.B. Bagci’s "Ghirardi-Rimini-Weber Collapse Theory and Whiteheadian Process Philosophy"
Authors: Kallfelz William M.
Published: December 2022

I examine G.B. Baga’s arguments for the Ghirardi-Rimini-Weber (GRW) interpretation of non-relativistic quantum mechanics as ideally suited for Whitehead’s philosophy. Much of Bagci’s claims are in response to Michael Epperson, who argues in the same vein in favor of decoherence accounts (Omnès; Zureck). Pace Epperson, I do not think that decoherence is the final arbiter here, and instead I contrast GRW with several other accounts addressing foundational problems of quantum theory (Finkehtein; Green; Peres and Temo; etc.), which aho account for relativistic covariance, while GRW does not. I argue that such latter research programs align themselves in a more convincing manner with Whitehead’s scheme, in epistemic as well as metaphysical senses, than GRW.
Process Ecology: Philosophy Passes into Praxis
Authors: Ulanowicz Robert E.
Published: December 2022

Mechanical reductionism, which deals entirely with homogeneous variables, will constrain and enable the activities of richly heterogeneous living systems, but it cannot determine their outcomes. Such indeterminism owes to problems with dimensionality, dynamical logic, intractability, and insufficiency. The order in any living structure arises via an historical series of contingencies that were selected endogenously by stable autocatalytic processes in tandem with, and usually in opposition to, conventional external influences (natural selection). The development of living communities thereby resembles a Heraclitean dialectic between processes that build up and those that tear down. Investigating this unconventional dynamic requires metaphysical assumptions that are complementary to those that have guided science over the past three centuries. The new dynamics can be represented in terms of weighted networks of interacting processes, which facilitate the statement of testable hypotheses. Network analysis thereby implements and tests ideas that heretofore could only be addressed as verbal propositions.
Whiteheadian Societies as Open-Ended Systems and Open-Ended Systems as Whiteheadian Societies
Authors: Bracken Joseph A.
Published: December 2022

In this essay I defend two interrelated theses. The first is that Whiteheadian structured societies are best understood as open-ended systems akin to those currently being proposed in the natural and social sciences by Stuart Kauffman, David Sloan Wilson, and Niklas Luhmann. The second is that an open-ended system is best understood in terms of an ongoing interplay of subjectivity and objectivity, which I derive from a modest rethinking of the workings of a Whiteheadian structured society.
Cosmos, Logos, and the Limits of Science
Authors: Valenza Robert J.
Published: December 2022

Following the introduction of the special and general theories of relativity and development of consequent cosmological models, the extent to which time and space play a starkly abstract role in physics has become more and more apparent. We examine here whether the full force of such abstract characterizations comes ultimately into opposition with the practice of science and implies some hard limitations on the scope of scientific discourse.
The Categoreal Scheme in Hua-yan Buddhism and Whitehead’s Metaphysics
Authors: Yu Yih-hsien
Published: December 2022

If, after a century of analysis there is a turn to synthesis, Hua-yan and Whitehead will become important resources. Especially given the radical difference of their historical contexts, their similarity is striking, but they differ on time. Whitehead is clear that relations to the future always differ in kind from those to the past, and Theravada Buddhists agree. But Hua-yan is open to a greater symmetry in enlightened experience.
Whitehead, Buddhism, and the Reversibility of Time
Authors: Yokota John Shunji
Published: December 2022

Pure Land Buddhism ascribes to Amida some of the roles ascribed to God by Whitehead. The failure of Whiteheadians to clarify how God can play these roles also leaves doubtful the claim of Pure Land Buddhism. On the other hand, Whitehead’s emphasis on perpetual perishing reinforces the original Buddhist teaching of impermanence and together they provide the basic insight for authentic life.
Death and the Dipolar Category of the Ultimate
Authors: Voskuil Duane
Published: December 2022

If the Category of the Ultimate requires every actual entity to be, as Whitehead says, both a processing subject and a superject existing objectively immortal, death of a personally ordered social nexus seems impossible since a personal nexus cannot die unless it has a last member. How that is possible is examined, concluding that actual entities of necessarily existing personal societies always have enough creative power to integrate their physical prehensions into new satisfaction/superjects, but others in contingently existing personal societie inevitably do not.
Allan’s Atheism
Authors: Ford Lewis S.
Published: December 2022

This article examines the strongest case to date in favor of a Whiteheadian atheism. But this case proves inadequate to account for genuine novelty.
Introducing a Time Horizon into Ethics
Authors: Hayashi Yoshihiro
Published: December 2022

Modern technology has radically altered the conditions for human action, endowing us with tremendous power to affect the future. Patterns of action that appear positive in their short-term effects must sometimes be judged unsustainable. Hans Jonas and Thomas Berry are among those who emphasize the necessity of transforming ethics in light of these considerations. In a Whiteheadian framework, this needed transformation is rooted in the nature of things.
Between Hartshorne and Molina: A Whiteheadian Conception of Divine Foreknowledge
Authors: Malone-France Derek
Published: December 2022

The doctrine of inerrant divine "middle knowledge" of future contingent events, first developed by the sixteenth century Jesuit theologian Luis de Molina, has resurfaced as a prominent position within contemporary debates over divine foreknowledge, creaturely freedom, and the ontological status of possibilities. As yet, the only substantive response to the new Molinism from a process perspectiv has come in a brief section on "Hartshorne and the Challenge of Molinism," in an essay on Hartshorne’s view of "The Logic of Future Contingents" by George W. Shields and Donald W. Viney, in Shields’ edited anthology Process and Analysis. Shields and Viney offer an insightful critique of Molinism. However, their use of Hartshorne’s understanding of possibility presents problems for those, like me, who prefer Whitehead’s more robustly realist notion of eternal objects. Here, I defend Whitehead’s Platonism from the main lines of criticism leveled against it by Hartshorne, while demonstrating that a "thick" conception of the objective content of the possible within the context of the divine understanding need not cross over into a deterministic conception of God’s foreknowledge, à la Molina.
