Authors: Neera Neera , Gopalan N , Murali H S
Published: November 2022

A total of 45 cereal samples (35 paddy and 10 sorghum) were collected from Mandya and Mysore districts of Karnataka during March, 2019 to study the mycotoxigenic Fusarium strains present in the field and market samples. All samples were brought to DFRL, Mysore and screened for Fusarium presence by agar plating method on Selective Fusarium Agar (SFA) containing streptomycin (1 mg/ml) with incubation at 25 ± 2°C for 3–5 days. In the study, almost 10 different Fusarium species association was revealed with the collected cereal samples. Fusarium species were micromorphologically identified and further confirmed by PCR-based detection using ITS1 and ITS4 primers followed by sequencing. PCR studies confirmed that all the tested fungal isolates belonged to Fusarium spp. with the amplicon size of 590 bp. NCBI data base confirmed the sequence similarity of 99 % to the genus Fusarium and accession numbers were obtained by submitting the sequences to the GenBank. The study disclosed the diversity in phytopathogenic Fusarium spp. in paddy and sorghum growing in different agro-climatic regions of Mysore and Mandya districts of Karnataka, India.

Published: November 2022

Some survivors of humidifier disinfectants (HDs) complain of chronic, inexplicable fatigue, and post-exertional malaise (PEM). Two-day cardiopulmonary exercise tests (CPETs) performed 24 hours apart (2-day CPET protocol) are increasingly employed to evaluate PEM and related disabilities among individuals with chronic fatigue syndrome (CFS). The purpose of this study was to assess the reproducibility of CPET variables in individuals who had been exposed to HD and to show that 2-day CPET is an objective means of differentiating between fatigue conditions in people with CFS symptoms who have been exposed to HDs. Twenty-nine HD survivors with CFS symptoms were enrolled in this study. To document and assess PEM in CFS, a 2-day CPET was conducted to measure baseline functional capacity (CPET1) and provoke PEM. Twenty-four hours later, a second CPET assessed changes in related variables, focusing on PEM effects on functional capacity. This CPET also measured changes in energy production and physiological function, objectively documenting PEM effects. In the 2-day CPET, the peak oxygen consumption (VO2peak), VO2 at ventilatory threshold (VO2@VT), time to reach VO2peak, and time to reach VO2@VT were significantly decreased (p<0.001). The peak O2 pulse and O2 pulse at VT also decreased significantly (p<0.001). A 6-minute walk test revealed significantly decreased distance (p<0.01). This is the first study to conduct a 2-day consecutive CPET in previously exposed HD participants with CFS symptoms. Our results confirm previous work that demonstrated abnormal responses to PEM in CFS patients. Therefore, a 2-day CPET is an objective measure to differentiate fatigue conditions in people with CFS symptoms who have been exposed to HDs.
Multiple-object Tracking Based on Movement Direction Assumption and Potential Re-appearance Position with Object Flow Visualizations
Authors: Yun Sup Lee , Ilao Joel
Published: November 2022

This paper proposes a multiple-object tracking (MOT) approach that adopts the tracking-bydetection strategy, which is composed of two steps: detection and tracking. This study aims to improve the tracking module by integrating a kernelized correlation filter (KCF). The filter is modified to be scale-adaptive to manage the varying size of the target object. Moreover, the tracking module’s data linking is performed in two steps, i.e. data association and reidentification (ReID). Here, two novel assumptions – namely, the movement direction assumption and potential re-appearance position – are incorporated. The first assumption considers the target object’s expected movement direction, while the second assumption postulates the possible position that a missing object may re-appear in. Using selected videos in 2DMOT2015 and PNNL Parking Lot benchmarking datasets, this study demonstrates that the proposed method outperforms the baseline model. In addition to MOT, this study further introduces a simple yet effective technique called trajectory accumulation to visualize the target objects’ flow of movement using the trajectories generated by the proposed tracker.

Published: November 2022

Base excision repair (BER) pathway involves repair of damaged DNA caused by spontaneous decay of DNA, reactive oxygen species, and ionizing radiation. Polymorphisms of genes involved in the pathway have been reported to be associated with cancer risk. In this study, the association of BER gene polymorphisms with breast cancer risk in Filipino women was assessed. The polymorphisms studied included X-ray repair cross-complementing group 1 (XRCC1, Arg399Gln), 8-oxoguanine DNA glycosylase (OGG1, Ser326Cys), and apurinic/apyrimidinic endonuclease 1 (APE1, Asp148Glu; –141T/G). A total of 186 participants (93 breast cancer cases and 93 breast cancer-free control) were recruited for the study. The genotyping of samples was performed using polymerase chain reaction with confronting two-pair primers (PCR-CTPP). The association of polymorphisms of BER genes with breast cancer risk and gene-environment interaction was determined using the unconditional logistic regression model. Distributions of OGG1 and APE1 genotypes were in Hardy-Weinberg equilibrium (HWE); however, XRCC1 genotype distribution deviated from HWE and was not further analyzed. The analysis showed that OGG1 Ser326Cys, APE1 Asp148Glu, and APE1 –141T/G had no significant association with breast cancer risk. Also, there is no significant interaction between the three BER gene variants and family history of cancer. Lastly, no significant increased risk was observed when the combined effects of risk alleles of the three BER gene variants were determined. In conclusion, the study suggests that OGG1 Ser326Cys, APE1 Asp148Glu, and APE1 –141T/G are not good indicators of breast cancer risk in Filipino women.

Published: November 2022

Zinc deficiency is linked to linear growth and is considered as one of the risk factors of stunting. Stunting persists as a public health problem in the Philippines, affecting 30% of children below 5 yr old. This study assessed the adequacy of dietary zinc intake and the prevalence and associated factors of serum zinc deficiency among preschool-age children 6–71 mo old. Data from the 8th National Nutrition Survey (NNS) conducted in 2013, involving 2,892 preschool-age children, were analyzed. Zinc intake was collected using two non-consecutive 24-hr food recalls, while dietary zinc inadequacy was intake below 100% of the estimated average requirement (EAR) for zinc prescribed by the 2015 Philippine Dietary Reference Intakes (PDRI). Serum zinc level was analyzed using atomic absorption spectrophotometry. Factors associated with zinc deficiency such as micronutrient status, wealth status, food security, and dietary adequacy were identified using multivariate logistic regression analysis. Almost half (47.2%) of preschool-age children had inadequate zinc intake. The national prevalence of serum zinc deficiency was 17.9%, and it is highest among children 6–23 mo old and those from rural, poorest, and food-insecure households relative to other subgroups. Poor wealth status was found to be a strong predictor of zinc deficiency (OR 4.0; 95% CI = 2.22–6.00). Stunting (OR 1.37; 95% CI = 1.06–1.76) and serum vitamin A deficiency (OR 1.80; 95% CI = 1.43–2.26) were associated with higher odds of zinc deficiency. Adequate vitamin A intake was an important protective factor against zinc deficiency. The odds of a child being zinc deficient is significantly predicted by poor wealth status, stunting, and vitamin A deficiency, while adequate nutrient intake serves as a crucial protective factor. Strengthening programs on micronutrient supplementation (including zinc), food fortification, and dietary diversification – combined with micronutrient-dense food consumption among preschool-age children – could help achieve long-term nutrition and health outcomes.
Molecular and Morphological Identifications of Anisakis Dujardin, 1845 (Nematoda: Anisakidae) from a Rare Deraniyagala’s Beaked Whale (Mesoplodon hotaula Deraniyagala, 1963) and Blainville’s Beaked Whale (Mesoplodon densirostris Blainville, 1817) Stranded Off Southern Philippines

Beaked whales are among the definitive host of the parasitic worm Anisakis Dujardin, 1845. In this study, molecular [using ribosomal internal transcribed spacer (ITS) region and mitochondrial DNA cytochrome c oxidase subunit 2 gene (mtDNA COX2)] and morphological (light microscopy and scanning electron microscopy) identifications of Anisakis from a rare Deraniyagala’s beaked whale Mesoplodon hotaula Deraniyagala, 1963 and Blainville’s beaked whale Mesoplodon densirostris Blainville, 1817 stranded in Davao Gulf, Southern Philippines are presented. Results conclusively revealed that the worm samples were A. ziphidarum, representing an additional geographical record for the species along the West Pacific region and a first record examined from the rare Deraniyagala’s beaked whale, representing a new host record for the species. Interestingly, both molecular and morphological data further revealed that the worms collected from Deraniyagala’s beaked whale consisted of two subgroups under the A. ziphidarum clade suggesting possible cryptic species, one of which is closely related to the Atlantic species while the other could be a local variant specific to the West Pacific.
Genetic Diversity and Structure of Oryza rufipogon Griff. Populations in the Philippines

Published: November 2022

Oryza rufipogon Griff., or “Rufi” in the Philippines, was previously known to be found only in Lake Apo, Bukidnon. However, a new population was identified in Lake Napalit in the same province. A better understanding of the genetic diversity of both Rufi populations using molecular methods may be beneficial to further ascertain its usefulness in rice breeding and in the development of effective conservation strategies. Population genetic analysis was conducted to estimate the degree of genetic diversity and population structure of the two Philippine Rufi populations using 98 genome-wide simple sequence repeat (SSR) markers. Four Oryza sativa indica and three O. sativa japonica cultivars were added for comparison. Results indicate that both Rufi populations exhibit low genetic diversity but with significant population structure and differentiation. Low genetic diversity suggests that both populations might be in a genetic bottleneck, perhaps due to observed unsustainable farming practices near their habitat and lack of awareness among locals of their importance. Also, geographical isolation that prevented gene flow between the two populations, as well as the unique climatic conditions between the two lakes might have contributed to the significant population structuring and differentiation. Thus, in situ and ex situ conservation should be observed for both Rufi populations in the Philippines.
Cytochrome C Oxidase Subunit I and II (COI and COII) Sequences Support Recognition of Papilio chikae Igarashi and Papilio hermeli Nuyda as Distinct Species

Published: November 2022

Papilio chikae and P. hermeli are two endemic swallowtail butterflies in the Philippines found primarily in the Cordillera region and Mindoro Island, respectively. Their species status is still subject to debate due to opposing interpretations of their genitalia and morphological traits. This study aims to delineate these taxa through the use of mitochondrial cytochrome C oxidase subunit I(COI) gene marker, with additional information on their cytochrome C oxidase subunit II(COII) gene. The COI nucleotide sequences from our Philippine P. chikae samples were surprisingly identical to P. hermeliEF514465.1 on the GenBank, whereas our P. hermelisamples showed a 100% similarity with P. hermeliEF514464.1.Based on our phylogenetic analysis, P. chikae and P. hermeli exhibit distinct COI barcodes supported by a high bootstrap value (85%). The P. hermeli voucher specimen with GenBank Acc. No. EF514465.1 clustered with our P. chikae samples, separate from the cluster containing our P. hermelispecimens. Nonetheless, the 3.1–3.4% genetic distance observed in the COI region supported by the formation of two separate clusters suggests species status for these taxa. Moreover, species-specific molecular markers obtained from the COII region displayed a 2.4% distance between these two taxa. These molecular markers could therefore be utilized to distinguish P. chikae from P. hermeli. Nevertheless, a thorough examination of their morphology, behavior, and ecology is still imperative to firmly establish their taxonomic status.
Richness and Distribution of Orchids (Orchidaceae) in the Forests of Mount Busa, Sarangani, Southern Mindanao, Philippines
Authors: Saavedra Aljohn Jay , Pitogo Kier Mitchel
Published: November 2022

Orchids are one of the most diverse yet threatened plant families in the world and the Philippines. Despite the new species discoveries of orchids in the country in recent years, diversity and distribution studies are still severely lacking. Here, we provide a list of orchid species found among different forest types in Mount Busa and provide information on the species’ altitudinal and vertical distributions and ornamental use. We recorded 108 species of orchids from 51 genera, of which 53 species are endemic to the Philippines and 15 species are known only to occur on Mindanao island. Species composition differed among forest types, with the MASLEF (mixed advanced secondary lowland evergreen forest) hosting the highest number of orchid species recorded, followed by the UMF (upper montane forest), LMF (lower montane forest), and MESLEF (mixed early secondary lowland evergreen forest). Our results suggest a relatively rich and distinct orchid diversity among different forest types in Mount Busa that reinforces the high conservation value of the mountain range.

Published: November 2022

Functional groups or guilds are now becoming popular in biodiversity conservation and monitoring as representative of the condition and status of a habitat as a whole. These can provide a rich source of additional evidence that can supplement evidence from studies based on taxonomic composition. In this study, we assessed differences in bird species and feeding guild assemblages across three habitat types within the Pantabangan-Carranglan Watershed and Forest Reserve (PCWFR), a major watershed in the Philippines located in the province of Nueva Ecija on central Luzon island. We sampled three habitat types during the wet and dry seasons from 2012–2016 using ground and canopy nets. After 4084 mist-net days, we captured 1191 bird individuals of 92 species and 41 families. Both species and feeding guild assemblages differed between habitats based on PERMANOVA (p = 0.001). Nineteen species and five feeding guilds differed in abundance between habitats. Our study demonstrated significant responses of the species and feeding guild assemblages of birds within the PCWFR to a disturbance gradient. We also found that feeding guild assemblage patterns were significantly correlated to species assemblage patterns. The use of guilds in bird monitoring can, thus, help facilitate the involvement of indigenous people and local communities, whose knowledge of birds is based on their observations of the environment, including traits that define these feeding guild classifications. However, there is potential to obscure the presence of taxonomically distinct lineages, such as the many endemic species and subspecies found on Luzon island and the Philippines. This concern is especially important in a megadiverse region like the Philippines. As such, we recommend the use of a functional approach in tandem with the traditional taxonomic approach in studying bird communities.
Butterflies and Moths of Kawa-Kawa Hill Natural Park, Ligao City, Southern Luzon, Philippines
Authors: Mape Niño , Concepcion Steven
Published: November 2022

With the scarcity of published lepidopterological studies in the Bicol Region, especially focusing on urban biodiversity, this study aimed to determine the species diversity of butterflies and moths in Kawa-Kawa Hill Natural Park, Ligao City, Albay, Philippines. A survey using visual encounter and photo documentation was conducted for nine field days in June–August 2020 in the three established sampling sites identified based on vegetation types – secondary forest, grassland, and bamboo forest. A total of 63 species of Lepidoptera comprising 50 species of butterflies and 13 species of moths were recorded. The butterfly family Nymphalidae (30%) was the most speciose taxon, while the moth family Lasiocampidae and Sphingidae (2%) both ranked the least. The highest species richness and diversity were recorded in the grassland (S = 48; D = 0.95), followed by the bamboo forest (S = 37; D = 0.94) and then the secondary forest (S = 31; D = 0.93). Despite its exposure to anthropogenic disturbance, Kawa-Kawa Hill is still diverse (D = 0.94) in Lepidopteran species – which include seven Philippine endemics, one Southern Luzon endemic, and an endangered species (Troides rhadamantus rhadamantus). These findings suggest that habitat modification in Kawa-Kawa Hill promotes butterfly and moth diversity.

Published: November 2022

The Busa Mountain Range hosts one of the last remaining forests in southern Mindanao, Philippines. Previous bird surveys were confined only to the northern slope, leaving the southern slope in Sarangani Province a relatively understudied area in terms of avian fauna. To augment this gap, we did a rapid inventory survey of bird presence in the Busa Mountain Range employing a combination of line transects, point counts, opportunistic listing, and observation from vantage points, which were supplemented by secondary data from a previous avifaunal assessment. We recorded a total of 116 bird species from 45 families and 88 genera. Despite the significant number in species tally, our survey of birds in the Busa Mountain Range is still inadequate because of the few field sites visited (10 localities) and limited survey time for each locality (82.85 person-hr on average). The presence of several threatened species (DAO 2019- 09: 16.37%, n= 19; IUCN V3.1: 13.79%, n= 16), endemic species (53.44%), and anthropogenic disturbance indicate the strong need for protection of the bird fauna and their habitats in the Busa Mountain Range.

Published: November 2022

Seagrasses are an important coastal resource that serves as homes and breeding grounds of fishes and other marine organisms and are useful indicators for the detection of changes in the coastal environment since they are vulnerable to bio-physical stressors. This study assessed the seagrass resources in terms of composition, percent cover, community similarity, and diversity in four municipalities (Banaybanay, Governor Generoso, Lupon, and San Isidro) situated in the southwest coast of Davao Oriental province facing Davao Gulf. Thirty-six (36) transects, each with ten quadrats arranged in an alternate manner, were laid perpendicular to shore yielding a total of 360 plots. A total of eight seagrass species were observed: Cymodocea rotundata, Enhalus acoroides, Halodule pinifolia, Halophila minor, Halophila ovalis, Halophila spinulosa, Syringodium isoetifolium, and Thalassia hemprichii. Governor Generoso (33.77%) and San Isidro (26.01%) were classified to have fair seagrass bed conditions while Banaybanay (24.31%) and Lupon with the lowest coverage (15.90%) had poor status. T. hemprichii dominated the seagrass community in Banaybanay and Governor Generoso while C. rotundata were dominant in Lupon and San Isidro. The two most abundant species, T. hemprichii (41%) and C. rotundata (34.48%), had fair coverage comprising 75% of the entire seagrass while the remaining 25% cover was shared by Enhalus acoroides (19%) and other five species with very poor cover (0.30–2.43%). Diversity analysis using percent cover data revealed low diversity with overall Shannon index, H’= 1.2955, evenness J = 0.6657, and Simpson’s index of diversity, D = 0.3577. Dice community of coefficient grouped Banaybanay, Governor Generoso, and San Isidro together, indicating high similarities while separating Lupon, which had the poorest seagrass condition in terms of coverage. The status of seagrass diversity on the southwest coast of Davao Oriental calls for immediate attention and effective strategies to alleviate poor conditions and protect the seagrass beds
Mapping Hotspots of Human Impact on Native Dendroflora Biodiversity in Cebu Island, Philippines
Authors: Quijano Isabella Pauline , Flores Mary Joyce , Patiño Chito
Published: November 2022

The continuing pressure on the natural environment exerted by human activities such as land conversion has been threatening to drive tens of thousands of species to extinction globally for decades. Species conservation requires identifying species ranges impacted by threats, which helps predict localized extirpations and potential extinctions. This paper assessed the human pressures that threaten the local biodiversity in Cebu Island, Philippines, to help prioritize actions to manage and mitigate human impacts on local biodiversity. Hotspots, where modeled dendroflora species richness is compromised, were identified through a spatial overlay of pre-defined high-resolution human pressure variables. A notable observation was that the largest and only protected KBA – the Central Cebu Protected Landscape (CCPL) – had the highest percentage occurrence of medium to high threats within its boundaries, which could be attributed to its proximity to highly populated municipalities and cities. More importantly, possible areas of refuge for key species were identified. These areas could be appropriated as local restoration sites by the local government units of Mt. Lanaya and Nugas forest in the south of Cebu since these KBAs had high dendroflora richness but with less occurrence of high threats. The resulting maps could also be used as important references for targeted conservation management programs to help mitigate the threats that are driving local species to their decline and for preemptive planning of local and national conservation agenda.

Published: November 2022

Population genetics has been widely employed in conservation studies to assess genetic diversity, gene flow, and population structure. This information can be used to understand the population’s fitness. The Philippine dawn bat Eonycteris robusta is a nectarivorous fruit bat that is ecologically important because of its capability to pollinate trees. It is categorized as “Vulnerable” in the Philippine Red List and the IUCN (International Union on the Conservation of Nature) Red List. Fragmentation and loss of forest habitats along with biogeographical factors might impact gene flow and affect the genetic diversity of this species. Thus, a population genetic study was done to assess gene flow and population structure of this species from two sites in the island of Luzon: Palanan, Isabela and Puning Cave, Doña Remedios Trinidad, Bulacan. Ten (10) microsatellite markers were developed from the whole genome of E. robusta and these were used for genotyping individuals. Observed heterozygosity (Ho) was generally lower than the expected (He), suggesting loss of heterozygosity. The inbreeding coefficient values (F) across all loci were greater than 0.5, which meant that mating between closely related individuals was frequent. A low level of gene flow was detected between Palanan and Puning Cave with the presence of structuring (Fst = 0.190 ± 0.003; Nm = 1.068 ± 0.020). Deviations from the Hardy-Weinberg equilibrium (HWE) were also observed for most of the loci tested. Clustering was also evident in the principal coordinates analysis (PCoA) plots, showing a distinct cluster of Puning Cave samples separate from Palanan, Isabela. This study has shown that within island clustering is possible, which may be driven by ecological factors such as discontinuity of available habitats for E. robusta or by biogeographical features like distance and topography

Published: November 2022

To increase flexibility or to develop covariate models in various ways, new parameters can be added to existing families of distributions or a new family of distributions can be compounded with well-known standard normal distribution. In this paper, a trigonometric-type distribution was developed in order to come up with flexible distribution without adding parameters, considering Exponential distribution as the baseline distribution and Sine-G as the generator. The proposed distribution is referred to as Sine Exponential Distribution. Statistical features, including the moment, moment generating function, entropy, and order statistics were obtained. The proposed distribution's parameters were estimated using the Maximum Likelihood method. Using real datasets, the model's importance was demonstrated. The newly developed model was proven to be better than its competitors.

En 2017 publiqué en Eikasía un artículo dedicado, como este, a Ricardo Sánchez Ortiz de Urbina, titulado «Hablar, leer, escribir». Ahora, en este merecido homenaje, vuelvo sobre aquellas impresiones intentando aplicar las enseñanzas de Urbina, inagotables, necesarias y esenciales. Es pues un acto de reconocimiento.

Escribir es una acción que afronta un horizonte impreciso, puesto que al inicio, en las primeras frases, no podemos intuir cual será su desarrollo, las variaciones, las complejidades, los obstáculos con los que tropezaremos a medida que avancemos en la escritura. Hay pues un aspecto teleológico en el verbo «escribir». Escribimos sobre esto o aquello, incluso por el «mero hecho» de escribir. Pero, en cualquier caso, «escribir» implica o requiere una idea reguladora, o un argumento, como Juan Benet destacaba como condición para escribir una novela.

Del Diálogo del Guerrero al Diálogo del Hogar: para una fenomenología de los celos

Published: November 2022

Estas líneas están escritas como homenaje a Ricardo Sánchez Ortiz de Urbina, con todo el cariño y con la esperanza de ser acogido con la benevolencia que demanda el ensayo. En todo caso, nunca podré dejar de agradecer a nuestro maestro que me permitiera salir sin brusquedad del encierro al que me había conducido el sujeto gnoseológico, el sujeto de la ciencia, siempre omnipresente en toda investigación. Siguiendo la estela de la matriz fenomenológica configurada por Urbina, entreví en el nivel superior ―el nivel de máxima ambigüedad―, y mediante trasposiciones sucesivas, el origen humano de los celos, que desbordan el simple comportamiento o el mero afecto. Los celos como fondo siempre desbordante en el proceso que nunca concluye de fijación de la identidad humana. Un camino que habían recorrido, con los medios de que disponían, los escritores del Barroco español en el contexto de los conversos hispanos y Miguel de Cervantes como centro.
La identidad del arte
Authors: Sánchez Ortiz de Urbina Ricardo
Published: November 2022

A principios del siglo XX se produjo la distinción entre conocimientos físicos clásicos y conocimientos físicos cuánticos. Con la relatividad especial (el espacio-tiempo y la equiparación de energía y materia), culmina la física clásica; y con la cuantización de Planck, se inicia una física nueva, con extrañas síntesis sin identidad: transprobabilidad. Pero, en 1915, apareció una distinción aún más profunda, la de los conocimientos propios (que engloban lo clásico y lo cuántico), y los conocimientos impropios. Todo empezó cuando, en la relatividad general de Einstein, no estaba claro que se cumpliese el principio sagrado de la conservación de la energía. Hilbert afirmó (su famosa Behauptung) que se trataba de un conocimiento impropio; pero no supo explicar el porqué. Fue la matemática Emmy Noether, experta en invariantes, la que, con sus dos teoremas de 1918, explicó la diferencia radical entre conocimientos propios (conservación de la energía, de los momentos lineal y angular, de las “cargas” ...), y los conocimientos impropios (segundo teorema). Pero la razón más profunda de la conservación impropia, que Noether encontró en los grupos de infinito no enumerable de Lie, está en el campo intencional de la fenomenología renovada. La encontramos cuando se recorre el campo intencional no “desde arriba hacia abajo” (el movimiento de la mínima acción), sino “desde abajo hacia arriba”: la simple invariancia sin atención al movimiento. Y ahí encontramos la sorprendente identidad del arte, frente a la identidad de la ciencia. El arte es una forma de conocimiento impropio, fuerte y englobante.
Nietzsche y la “visión del mundo” (Weltanschauung) en El nacimiento de la Tragedia

Published: November 2022

La “visión del mundo” (Weltanschauung) es una cuestión que ha sido pasado por alto por un gran número de investigadores en el pensamiento de Nietzsche, aunque aparece con frecuencia en sus escritos. Pocos intérpretes han tocado esta noción, y dirigen únicamente su atención en puntos muy concretos de vista, destacando algunos aspectos menos esenciales de la misma. Parece que el concepto de Weltanschauung nunca ha sido considerado como un objeto independiente dentro de la obra de Nietzsche. Este trabajo pretende elaborar un recorrido interpretativo, resaltando su importancia y, sobre todo, el lugar que posee dentro de uno de sus primeros escritos, El Nacimiento de la Tragedia.

Mujer e histeria. El Real lacaniano como espacio de habitancia revolucionaria
Authors: Valdés Alicia
Published: November 2022

La relación entre el inconsciente y la revolución ha sido ampliamente estudiada por Skott-Myhre (2014). Este autor defiende la idea del inconsciente como el espacio potencial para la revolución, ergo, la subjetividad neoliberal ha de ser desafiada al nivel del deseo inconsciente. La presente conferencia tiene como objetivo seguir la línea de argumentación esgrimida por Bethany Morris (2017) en la que se define al sujeto mujer como un sujeto que posee un surplus de inconsciente, elemento que determina a la mujer como sujeto revolucionario. Partiendo de esta capacidad revolucionaria del sujeto mujer, esta conferencia defiende la idea de que la mujer no existe, sino que ex-siste desde fuera de la realidad, habitando así un espacio de vulnerabilidad y resistencia que le permite actuar como un sujeto revolucionario mediante la puesta en marcha del discurso de la histérica. A través de la traducción político-feminista de las ideas lacanianas de la posición sexual y del discurso de la histérica proponemos la introducción de una lectura heterodoxa del Real lacaniano como un espacio de habitancia política disruptiva.
La sinrazón y la razón sistemática: apuntes sobre psicopatología en clave kantiana
Authors: G. Ferrer Soledad
Published: November 2022

Dice Kant que la locura no consiste en un desarreglo de la razón. No es que el loco razone incorrectamente, sino que su razonamiento opera desde otros presupuestos diferentes y se aplica a otros datos, pero sus principios siguen siendo los mismos. La oposición de Kant a todo innatismo le lleva, entre otras cosas, a hablar de usos más que de contenidos de la razón. Y entre esos usos están los de la razón científica, los del entusiasmo revolucionario, los del fanatismo y también los de la locura. La psicología moderna ha dejado de lado toda la reflexión kantiana acerca de la psicopatología que, aunque fragmentaria y asistemática, aún puede proporcionar consecuencias interesantes en este terreno. Vamos, pues, a analizar alguno de los rasgos de este uso de la razón que genéricamente se ha llamado locura y que cobran una especial relevancia desde las críticas que desde hace ya unos 50 años se le han venido haciendo a una cierta medicalización de la psicología. Este análisis habrá de remitirnos irremediablemente al problema de la constitución de la subjetividad y tendremos que enfrentarnos al nuevo concepto de sujeto que Kant propone a la filosofía y que todavía, en mi opinión, dos siglos y medio después, no hemos acabado de entender. Sean, pues, estas reflexiones una modesta contribución también a este entendimiento.
Los principios ontológicos del pensamiento de Antonio Escohotado en Realidad y substancia
Authors: Molina Ruiz Santiago
Published: November 2022

El presente trabajo persigue aclarar y explicitar los fundamentos ontológicos presentes en el tratado Realidad y substancia, de Antonio Escohotado. De modo sintético el sujeto se funda en la nada el recorrido de la esencia, que se redefinirá como invenir para alcanzar el mayor grado de objetividad en el acto, en la actividad de lo real. Al fin, inmerso en una realidad dinámica se postula la vida, ya no como sujeto, para ahondar en la experiencia como un tránsito en el que el conocimiento es posible dentro de lo indeterminado.
Los derechos de los gobernados en el debate en torno al orden jurídico en la filosofía de Michel Foucault
Authors: Blengino Luis Félix
Published: November 2022

En artículo se propongo analizar el problema del «derecho de los gobernados en Foucault» a partir de algunos artículos del dosier «Michel Foucault y el derecho» de la revista Dorsal, n.° 7. A partir de los principales problemas y argumentos presentados en tales artículos procuraré organizar los ejes centrales que articulan el debate actual en torno a la cuestión del derecho en la obra de Michel Foucault. En un segundo momento, a partir de dos conceptos expondré una cuestión insuficientemente problematizada en dicho dosier. A saber, los conceptos de «derecho del pueblo» y «deber de los gobernantes» y el problema del alcance de los derechos de los gobernados así como las condiciones de su ejercicio y las garantías que implica.

Sexo, estirpe y estilo en la aproximación de Heidegger a la poesía de Trakl
Authors: Alvarado Cabellos Ángel
Published: November 2022

El presente texto constituye, por un lado, una continuación de una aproximación materialista al concepto de “raza” a partir de los Cuadernos negros de Heidegger, la cual nos llevó, luego de reconocer su carácter análogo a la “corporalidad”, a pensarla no como una determinación naturalista o biológica, sino como la posibilidad de un “mestizaje ontológico”. Por otro lado, “sexo”, “estirpe” y “estilo” hacen alusión a la polisemia del concepto de “Geschlecht” como una figura de lo que hemos llamado la ambigüedad fenomenológica del eros en términos de una “prohibición y transgresión arquitectónicas”. Ello se traducirá, por un lado, en la prioridad del “estilo” como reunión del decir poético en lo impronunciado del poema, y no, como propondremos, en la “excripción” de una “transposición metonímica”, y, por otro lado, en el silenciamiento por Heidegger de la figura del “incesto” en la poesía de Trakl.
Moralidad sin concepto Estudio interdisciplinar
Authors: Colón Rodríguez Ilia
Published: November 2022

La interioridad de lo viviente ha sido ignorada en una descripción científica del comportamiento humano. Hoy en día, sin embargo, la autopoiesis como paradigma de auto-organización, ha continuado incorpo- rando esos primeros atisbos de la interioridad de lo viviente que Kant desarrolló en la tercera Crítica. No hay organismo sin teleología y no hay teleología sin interioridad, nos dice, y sin un segmento teleológico el proyecto total de la moral se vuelve ininteligible. Hay un cambio de una ética basada en el imperativo categórico a una moralidad sin concepto basada en otro aspecto del imperativo categórico presente en la estética kantiana. Con F.Varela surge la convicción de la inminencia de un cambio de paradigma que se trasluce como la primacía de lo concreto y la oposición a todo análisis deliberado e intencional. Estas características ya se habían manifestado en Kant y en Husserl como el cambio de lo exterior a lo interior, donde prima el abandono de toda regla o principio y la contundencia de la evidencia intuitiva. Se han de reconocer la importancia de los impulsos pre-conscientes y los instintos, por lo cual he incluido un Apéndice. Este camino dio lugar a las experiencias límite de lo sublime y de la epojé ética universal, la cual, según N. Depraz, filósofa francesa especializada en Husserl, no tienenada de misterioso o esotérico aunque está lejos de ser autoevidente.
Sobre el problema ontológico en la ciencia: una alternativa para la investigación cualitativa en función de Max Scheler
Authors: Mujica Johnson Felipe Nicolás
Published: November 2022

La ciencia a lo largo de su historia ha estado fundamentada por múltiples enfoques filosóficos, sin embargo, han existido dos tradiciones hegemónicas que componen el dualismo de la investigación cualitativa y cuantitativa. En este artículo, además de criticar dicho dualismo, se propone una ontología alternativa de investigación cualitativa que supere el reduccionismo subjetivista. Para ello, se considera la concepción de la realidad de Max Scheler. En dicha nueva ontología, la ciencia cualitativa estudiaría un mundo compuesto por aspectos objetivos y subjetivos. En este sentido, su objeto de estudio se ampliaría a diferentes posibilidades, por ejemplo, la intención de explicar, predecir, controlar, explorar y comprender los fenómenos de la realidad.
Del cuerpo o el combate del pensamiento. Notas agónicas entre filosofías y deportes
Authors: Diaz Santiago
Published: November 2022

El cuerpo es el espacio de pensamiento que permite acercar la actividad del pensamiento filosófico y la reflexión deportiva. Este trabajo no trata de elaborar una tesis sobre la filosofía del deporte, sino encontrar un agón común que motive a pensar tanto en la filosofía como en el deporte. Con esto se intenta proponer, a partir de las filosofías de Gilles Deleuze y de Michel Serres, que el cuerpo es una fuerza que libera un combate sobre el pensamiento, sea en lo filosófico como en lo deportivo. En ambos casos, el cuerpo y sus tensiones, moviliza el pensamiento en ambas disciplinas citadas, provocando un devenir- atleta del filósofo y un devenir-filósofo del atleta.
Sobre el tejido histórico y su fundamento ahistórico
Authors: Aguirre Martínez Guillermo
Published: November 2022

Se comprende un concreto tejido histórico como un constructo. La aceptación de esta condi-ción irreal permite relativizar las ideas que sostienen dichos constructos, mientras que su comprensión como objetos absolutos nos sumerge en el curso trágico de la historia, esto es, en un magma de dinámicas dialécticas. Comprendemos, asimismo, que sin una conciencia ahistórica de lo existente, tanto en un ámbito colectivo como en uno individual, el sujeto de-viene en esclavo de sus propias ideaciones.

The COURAGE Registry: A Gateway to the Cultural Heritage of Eastern European Nonconformism

The COURAGE Registry is a digital research tool that allows exploring the legacy of cultural opposition in former Eastern European socialist countries by cataloging and describing relevant collections on dissident culture across Eastern Europe and worldwide. The linked database reveals a great variety of nonconformist cultural practices that were formerly largely unknown and promotes comparative research of similar phenomena in Eastern European societies and cultures. The researchers on the project tended to treat visual sources as traces of the past equally as important as written documents. Images were not only illustrations of the given narratives but, in some cases, visual documents were the only sources that preserved the memory of the alternative or underground activity, while in other cases, it was the act of taking pictures that resulted in the confrontation with official cultural policy. This article aims to provide insight into the basic dilemmas and issues that the project faced dealing with images for the database through three examples. Firstly, we focus on the photo documentation of an exhibition of the Hungarian art group Inconnu that was made by the secret police following the destruction of the artworks. Secondly, we show how photos were also taken by official photographers who operated in the so-called “grey zone.” Finally, our third example refers to Fortepan, a unique public initiative that focuses on the digital preservation of private photographs created between 1900 and 1990.
Servitization in the Manufacturing Industry: Where Do We Stand? Where Do We Come From?
Authors: Akalan Rodi , Böhm Eva , Eggert Andreas
Published: November 2022

Manufacturers are increasingly shifting their strategic focus from products to services to create customer value and defend a competitive edge in the marketplace. The transition process from product- to service-centric logic is referred to as servitization. Despite a large and growing body of academic literature, we are missing a descriptive view on the current state and the varying transition trajectories towards servitization in manufacturing industries. Against this backdrop, we provide a comprehensive empirical analysis of the servitization process in the U.S. manufacturing industry over the last 10 years. Using a unique panel dataset of 1,381 U.S. manufacturers, we draw a pronounced picture of firms’ servitization trajectories. Our descriptive results establish servitization as an ongoing trend in several sectors of the manufacturing industry. The commercial machinery and electronic equipment sectors put the strongest emphasis on services, while services play only a minor role in the chemical products sector. Moreover, we distinguish different service types and reveal their specific role in the servitization process. Product-oriented services, such as maintenance and repair services, have reached a high yet saturated level of strategic importance; customer-oriented services, such as systems and solutions, have become the major focus of the ongoing servitization process. A fine-grained analysis reveals considerable differences between large and medium-sized enterprises. These insights help managers to benchmark and improve their servitization strategy.
