The Brazilian sectoral innovation system in the field of Tissue Engineering and Bioprinting: actors, challenges and perspectives
Authors: Massaguer Pedro Xavier Rodriguez , Millás Ana Luiza Garcia Massaguer
Published: February 2020

The objective of this work is to map the main actors within the Brazilian innovation system framework in the field of tissue engineering and bioprinting, and analyze the main conditioners related to entrepreneurship and innovation. While keeping as a backdrop, the history of 3D Biotechnology Solutions startup, its challenges and projects. Tissue engineering is a subcategory of regenerative medicine with the purpose of repairing or substituting, partially or completely, tissues or organs that have been affected by some disease or lesion. The conventional methods used for the production of these biomaterials via tissue engineering do not have the capacity to mimic the reality of native structures in the nano, micro and macro scales, while guaranteeing the reproducibility andscalability ofthematerials. Technologies such as 3D bioprinting or additive manufacturing could change the way that many diseases are treated in the medium term by replacing the damaged tissues with custom bio-similar constructs. Mapping and reflections based on the innovation systems framework contribute to organize stimulus policies, stimulate interaction between actors, identify gaps and technological demands and periodically organize the analysis and expansion of this system in Brazil.

Published: February 2020

Biopolymers such as polysaccharides are compounds that have functional groups and they are very susceptible to be used in chemical modifications and also allows them to synthesizer of new copolymers (used as graft-like chains). Poly (N-Isopropylacrylamide) PNIPAm, is a thermosensitive synthetic polymer widely used in the preparation of intelligent gels for the biomedical field, but have some limitations in use as biodegradable matrix or scaffolds. In this research wered the synthesis and characterization of copolymers their PNIPAm grafted with the polysaccharides: chitosan (CS) or hyaluronic acid (HA), were performed to obtain new biodegradable and biocompatible biomaterials that conserve the intelligent character (thermosensitivity).The PNIPAm was in first chemically modified with 3-butenoic acid in order to generate carboxyl end groups on the graft-polymer chain (PNIPAm-co-COOH) which serve as anchor points and then covalently graft the polysaccharides. For the specific case of grafting with hyaluronic acid, it was necessary to perform a second modification using piperazine (PIP) and obtain the graft-polymers PNIPAm-co-COO-g-PIP. All this modification process was previously reported (Carrero et al, 2018). In this case, the polysaccharides used as grafts-like chains were: (1) chitosan oligomers obtained by acid degradation and (2) hyaluronic acid. The characterization of all copolymers obtained was follow by infrared spectroscopic (FT-IR); the differential scanning calorimetric (DSC) technique was used to determine the lower critical solution transition temperature (LCST), resulting in the range of 29-34 °C. Its morphology was studied using scanning electron microscopy (SEM), but previously was simulate an inject process, for the reversible gel character presented by these novel copolymers; resulting a high porosity and interconnection between pores (scaffold-like micrometric structures). Hemocompatibility assays were performed on agar/blood systems, showing non cytotoxicity. All these results give these graftcopolymers a high potentiality of use as scaffolds in tissue engineering and also for pharmacological applications.

Authors: Garcia Claudio Fernandes , Martins Virginia C. A. , Plepis Ana M. G.
Published: February 2020

To obtain a material with potential for use in tissue engineering, anionic collagen was obtained from porcine serosa (S) and bovine tendon (T) by alkaline hydrolysis for 72h. Part of this collagen was mixed with water to obtain 4 % (weight/weight) collagen suspension and part was solubilized in acetic acid pH 3.5 to obtain 1.5% (w/w) gel. The suspensions were mixed with their respective gels (2:1) (suspension: gel) and grape seed extract, whose main product is proanthocyanidin, was added at concentrations of 0.03% and 0.5%, thus obtaining the scaffolds SC (serosa collagen suspension and gel), TC (tendon collagen suspension and gel), SCP003 (SC with 0.03% extract), TCP003 (TC with 0.03% extract), SCP05 (SC with 0.5% extract added) and TCP05 (TC with 0.5% extract). The materials were analyzed by differential scanning calorimetry (DSC), scanning electron microscopy (SEM) and characterized by phosphate buffered saline absorption assay and in vitro biological stability assay. By DSC it is observed that the addition of 0.5% of extract increases the denaturation temperature (Td) of collagen, indicating that at this concentration the extract acts as polymer crosslinking agent. SEM shows disorganized cross-section pores in all scaffolds, not exceeding 130 ?m. Absorption and degradation assays indicated that the addition of 0.5% extract increases the absorption of phosphate buffered saline (PBS) by the scaffolds and decreases the degradation percentage by collagenase. These results suggests that the scaffolds can be used for different applications, e.g. as hemostatic agent.

Authors: Morais Fernanda Gonçalves de Abreu Rocha de , Oliveira Rayssa Caroline de , Gusmão Ricardo Otávio Maia
Published: February 2020

Introdução: A clínica com a psicose produz enigmas que se apresentam no contexto da Atenção Psicossocial e instituições. Este estudo de revisão narrativa teve por objetivo produzir considerações teóricas e críticas acerca das especificidades à clínica da psicose a partir das contribuições da psicanálise. Revisão Bibliográfica: em Freud, utilizou-se: “Caso Schereber” (1911/1996), “Introdução ao narcisismo” (1914/1996), “A teoria da libido e o narcisismo” (1916-1917/1996), “Neurose e Psicose” e “A perda da realidade na Neurose e Psicose”, ambos de (1924/1996). Em Lacan, usou-se: “Seminário - livro 3 “As Psicoses” (1955-6/1998) e “De uma questão preliminar a todo tratamento possível na psicose” (1958/ 1998). Além disso, artigos de  estudiosos de Freud e de Lacan foram usados. A discussão foi apresentada através dos seguintes tópicos: Teoria do narcisismo na psicose; As manifestações de corpo na clínica da psicose; O desencadeamento psicótico e a estabilização; A questão da transferência na psicose; e Impasses institucionais na clínica da psicose. Considerações Finais: as alterações no processo da linguagem implicam nas manifestações bem características dessa clínica, como exemplo acontecimentos de corpo, alucinações e delírios. Apesar disso, Lacan em seu ensino propõe a possibilidade de pensar o manejo da transferência na clínica da psicose pela via do secretariado.

Cancer is an uncontrolled growth of rapidly dividing cells.  Decreased efficacy of current anticancer drugs urges to further screening and investigation for a better alternative to current chemotherapeutics. Natural products of marine origin are great sources of potential new drugs of enhanced biological activities. Thus, the work aims to investigate the cytotoxic effects along with the mode of cell death exerted by SC-8, SC-9, HN-3, HN-4 and HN-5 fractions prepared from Stichopus chloronotus and Holothuria nobilis marine-sponge on the human cervical cell line, HeLa. The fractions produced effective cytotoxicity with IC50 values at 72hr of less than 30 μg/ml in the order of HN-3 > HN-4 > SC-9 > SC-8 > HN-5. These fraction induced cytotoxicity via mediating apoptosis in HeLa cells. The early apoptosis was done by fractions via exposure of protein phosphatidylserine (PS) to the outer leaflet of the plasma membrane and late apoptosis confirmed due to the presence of fragmented DNA in treated cells. The presence of potentially bioactive compounds in these fractions might be responsible for inducing apoptosis and, thus, own potential to be a successful candidate for exploring forthcoming chemotherapeutic drugs

Sleep is a naturally recurring state of mind and body in which the main features are the changes in the level of consciousness, reduced sensory and motor activity and reduced interactions with the environment. We need to have adequate sleep to maintain an optimal health and wellbeing.  Human beings need to sleep at least 6 hours during night to maintain optimal health. People who are sleeping five hours or less than five hours can alter the level of blood pressure. Sleep promotes general health, concentration and regulates the blood stress hormones and it keeps our nervous system healthy. If a person doesn’t have adequate sleep for a longer period, can change the level of stress hormone in the blood and it can increase the level of blood pressure. This study was done to find out the relationship between quality of sleep and the level of blood pressure among working adults. The descriptive research design was used to assess the relationship between qualities of sleep with the history of changes in the level of blood pressure of working adults. The study was done among the working people who are living in Jazan region. Based on the inclusion and exclusion criteria, a total of 30 participants were selected by using convenient sampling technique. The Quality of sleep of the participants was assessed by using Pittsburgh Sleep Quality Index questionnaire (PSQI). The total number of male participants were 4 and female participants were 26. Majority of them were in the age group between 30 and 40 years, and most of them had a preference for mixed food habits. Majority of them were in the age group between 30 and 40 years, and most of them preferred mixed food habits. Assessment of the quality of sleep of participants shows that overall 60% of the participants have poor sleep quality.

The crude proteins were isolated using 0.125 M Tris-HCl with 50 mM NaCl at pH 7.4. The protein content of the crude extract was determined using the Lowry assay and was found to be 4.28 mg/mL.  The major band which corresponds to the major protein has an approximate molecular weight of 20 KDa. The isolated crude proteins were subjected to enzymatic digestion using pepsin, trypsin, chymotrypsin, and thermolysin for 3, 4, 12, and 24 hours. The 24-hour digest was found to have the highest percent anti-Angiotensin Converting Enzyme (ACE) activity (36.02%) while the 12-hour digest was found to have the highest anti-oxidative activity (33.14%) using 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. The 24-hour digest was subjected to Ultra-Performance Liquid Chromatography (UPLC) to determine the peptide fraction responsible for the ACE inhibitory activity. Three peptide fractions (PF1, PF2 and PF3) were chosen and PF2 exhibited the highest percent inhibitory activity (32.21) against ACE. PF2 was subjected to thin layer chromatography (TLC) and the possible identity is EK based on the Rf value traveled by glutamic acid (E) (0.43) and Lysine (K) (0.13). In silico analysis was done to correlate the results with the presence of putative peptides with antioxidative and antihypertensive activities. Results showed that antihypertensive peptides EK, GS, TY, FNE, FP, LKA, PT, PP, FAL and antioxidative peptides IR and VPW were found based on the sequence of the protein in “Saba” banana. The presence of the antihypertensive peptide EK was verified using thin layer chromatography (TLC).

Authors: Ganado Rey Joseph J. , Franco Francisco, Jr. C.
Published: February 2020

The increasing oil demand and exhaustion of reserves have initiated stimulus to search for new and sustainable sources of fuels and fine chemicals. Lignocellulosic biomass turned out to be a promising and renewable feedstock for these applications. 5-hydroxymethylfurfural (HMF) is one of the most promising building blocks for bio-based chemicals that can be derived from lignocellulosic biomass which can be potentially applied for large scale production. However, one of the main factors holding its transition is the need for sustainable, green and financially feasible processes. This review provides the studies made towards catalytic systems used for HMF production, as well as the various solvents and heating system applied. Research efforts to unravel the interactions among catalysts, solvents, and heating systems are encouraged, thereby engineering a synergistic conversion system for biomass valorization.

Published: February 2020

A kinetic study for the phosphorus release of a formulated CaHAP-Z fertilizer was done to observe its behavior when applied to clay loam soil. The study of release kinetics of CaHAP-Z was done along with CaHAP and the control fertilizer Solophos™ to determine whether the formulated fertilizer can be an alternative for the conventional fertilizer. Results showed that the formulated fertilizer CAHAP-Z contains 3.73% phosphorus with 513.10 nm particle (Dynamic Light Scattering) indicating that the formulated fertilizer can be classified as a nanofertilizer. The formulated CaHAP-Z fertilizer showed the slowest release kinetics compared to the controls. In addition, this study showed that the simple Elovich kinetic model is the general equation that best fits to describe the phosphorus release of fertilizers.
Alkali Lignin from Talahib Grass (Saccharum spontaneum L.) as An Adsorbent for Chromium (III) and Phenolphthalein: Analysis of the Adsorption Kinetics and Mechanism
Authors: Marquez Kevinilo P. , Ramos Rufus Mart Caesar R.
Published: February 2020

The study aims to quantitatively assess the capability of lignin extracted from Saccharum spontaneum L. (talahib grass) as an adsorbent of chromium (III) and phenolphthalein in aqueous solution through kinetic methods. Results show that using lignin as an adsorbent, the percentage removal for both chromium (III) and phenolphthalein in aqueous solution are 31.70% and 74.98%, respectively, based on the optimum exposure time of the adsorbent, which is 6.5 hours for chromium (III) and 60 minutes for phenolphthalein. Results from the mechanistic analysis show that a pseudo-second order adsorption kinetic model fits better than a pseudo-first order model for both substrates. Also, among the six selected adsorption isotherm models used in this study, the Flory-Huggins isotherm can best predict the properties of the adsorption process of both phenolphthalein and chromium (III) at equilibrium. Further improvement of the extracted lignin through various physical and chemical modifications may improve its ability to remove the contaminants.

Published: February 2020

Numerous cases of arsenic (As) poisoning from contaminated groundwater have been reported worldwide including the Philippines. The maximum contamination limit has been set by World Health Organization (WHO) for arsenic in drinking water at 10 ppb. This study determined the As(III) and total As content of groundwater samples in selected sites of Bulacan, Batangas, and Laguna by differential pulse anodic stripping voltammetry (DPASV). The pH, temperature, conductivity, total solids, turbidity, and salinity of the groundwater samples were also determined during sample collection. Groundwater samples from Laguna were naturally warm, with collection temperatures exceeding 30 oC, compared to water samples from Batangas and Bulacan ((T = 27 to 29.5 ˚C). The pH and turbidity of all samples were found to comply with the limits based on acceptability set by the WHO and the Philippine National Standards for Drinking Water (PNSDW). However, some samples had total dissolved solids and salinity beyond the limits set by the WHO and PNSDW guidelines. Moreover, some of the samples tested contained arsenite As(III), the more toxic form of arsenic, above 10 ppb whereas only one water sample tested had less than 10 ppb total arsenic content.

Hydrocolloids retard lipid digestion in whipping cream
Authors: Srikaeo K. , Doungjan S.
Published: February 2020

This paper evaluated the effects of two hydrocolloids, pectin and carrageenan, on physical
properties and lipid digestion of whipping cream. Hydrocolloids were added to the creams
at 0.5, 1.0 and 1.5% by weight. Their physical properties and lipid digestion were
examined. It was found that both pectin and carrageenan affected lipid droplet size and ζpotential of the emulsions, causing the volume-surface average diameter to decrease while
the net negative charges of the lipid droplets increased. Hydrocolloids provided the key
benefits to whipped creams as they improved foaming properties and delayed lipid
digestion rate. Overrun and serum loss of the whipped creams were improved.
Hydrocolloids reduced the rate of lipid digestion as evidenced by lipid droplet
aggregations either by coalescence or flocculation mechanisms. The released free fatty
acids which are the end products of lipid digestion were reduced as a consequence of
hydrocolloid addition. The decrease of lipid digestion rate depended on the types and
concentrations of hydrocolloids. Carrageenan was found to be more effective than pectin
in terms of delaying lipid digestion.

Fenton Oxidation using Easily Recoverable Catalyst of Magnetite (Fe3O4) as an Efficient Approach to Treatment of Rhodamine B Dyeing Effluent in Traditional Fabrics Industry
Authors: Prasetyo Imam , Akbar Febry , Prabandari Anindya Widi , Ariyanto Teguh
Published: February 2020

A direct release of dye wastewater to a water environment without pre-treatment could cause negative impacts. To solve them, an effective method for degrading wastewater contaminants is needed. In this research, the Fenton reaction using Fe3O4 catalyst for removal of wastewater contaminants taken from a traditional fabrics industry was studied. For this purpose, reaction temperature was varied in the range of 27–90°C. Furthermore, catalyst concentration was also varied in the range of 2–6 g/L solution. The results showed that increasing both temperature and catalyst concentration will increase the performance of the Fenton reaction in degrading wastewater contaminants. The contaminant degradation was measured by detecting chemical oxygen demand and inspecting the color of wastewater. The highest reduction of color intensity was 98.96% at 90°C temperature and 2 g Fe3O4/L solution.

L’avènement des technologies de l’information et de la communication (TIC) dans la vie quotidienne et professionnelle nous pousse à profiter des avantages de l’accès à ces outils dans le domaine de l’enseignement et l’apprentissage du français en Iran. Les TIC nous conduisent à une nouvelle interpénétration des lieux et des pratiques  de formation. Grâce aux classes inversées, les contextes traversent les quatre murs de la classe. La façon de « faire la classe » se transforme en un modèle plus pratique encourageant des méthodes pédagogiques et des activités interactives pendant le temps précieux de la classe. Le partage des savoirs, la régulation de l’apprentissage par des partenaires pédagogiques et l’interactivité augmentent dans l’espace d’apprentissage.

La nécessité de la prise en considération des paramètres locaux nous amène à une application contextualisée et appropriée de la classe inversée qui aurait des effets considérables sur l’évolution des pratiques d’enseignement et d’apprentissage du FLE en Iran. Cette étude a donc pour origine deux questions à répondre : quels sont les facteurs contextuels et éducatifs qui influent davantage sur l’application contextualisée de la classe inversée dans le cours du FLE en Iran ? Quels sont les enjeux de l’application des TIC dans la mise en place de la classe inversée ? Nos résultats s’inscrivent au croisement d’entretiens semi-directifs avec les enseignants du FLE et de questionnaires comprenant des questions ouvertes et des questions fermées auprès des apprenants du FLE en Iran. Nous avons montré l’importance de la prise en considération des facteurs contextuels et éducatifs dans l’introduction de nouvelles démarches telles que la classe inversée ainsi que les enjeux de l’application des TIC dans les cours de français en Iran.

Ispahan, moitié du monde Dimension géocritique de l’espace dans Vers Ispahan de Pierre Loti Et L’Usage du monde de Nicolas Bouvier
Authors: Tork Ladani Safoura
Published: February 2020

La littérature décrit le lieu réel et géographique tout en profitant de l’imagination d’une manière très neuve en le transformant en un espace imaginaire et rêvé. Les villes et les lieux décrits dans les récits de voyage fascinent de plus en plus les lecteurs passionnés par l’Ailleurs. Dans cet article, nous avons essayé, à l’aide de l’approche géocritique de Bertrand Westphal, d’examiner l’image d’Ispahan dans Vers Ispahan de Pierre Loti, voyageur et écrivain français qui a visité l’Iran à l’époque qâdjâr à la fin du XIXe siècle, et L’Usage du monde de Nicolas Bouvier qui a parcouru l’Iran au XXe siècle à l’époque Pahlavi. En s’appuyant sur quatre éléments principaux de la géocritique comme la multifocalisation, la polysensorialité, la stratigraphie et l’intertextualité, on va examiner comment les deux voyageurs ont essayé chacun à son tour de représenter une image spéciale et unique de cette ville avec un décalage d’un siècle. Une image bien poétique, riche et pleine de figures littéraires chez Loti qui l’appelle “ la ville des roses ”, mais parfois avec un sentiment de la nostalgie du passé chez Bouvier. Celui-ci représente alors la ville en une image brève, associée au sentiment de l’absurdité face à cet “autre monde”.
L'islamisme, le temps et la femme dans Je viens d'ailleurs de Chahdortt Djavann
Authors: Nini Karim Zakaria
Published: February 2020

Chahdortt Djavann est une écrivaine franco-iranienne de langue française installée en France depuis 1993. Ayant passé sa jeunesse en Iran et ayant vécu la Révolution iranienne, elle écrit son premier roman, Je viens d’ailleurs (2002), en français, une langue qu’elle ne connaissait pas à son arrivée en France. Dans ce roman autobiographique, Djavann raconte son retour en Iran des années après avoir quitté le pays. A la recherche de l’Iran de son adolescence, Djavann se heurte à la réalité brutale d’un pays qui a rompu avec son passé. Un pays qui écrit désormais une nouvelle page de son Histoire, une page de laquelle le passé de l’écrivaine, son militantisme, ses amitiés et ses bons souvenirs sont effacés.

Dans cet article, il sera question de montrer comment l’écrivaine livre dans son premier roman un point de vue franc et acéré sur la société iranienne postrévolutionnaire. Nous proposons ainsi d’étudier comment la société iranienne régie par l’islamisme est écrite et représentée dans le roman de Djavann. Dans Je viens d’ailleurs, le persan est écrit en français et la société iranienne postrévolutionnaire est décrite au prisme de la francophonie. Héritière du lyrisme persan et hôte de la culture francophone, Chahdortt Djavann illustre le mariage parfait entre deux cultures littéraires à la poétique exacerbée.

Précurseurs d’une esthétique minimaliste : Samuel Beckett et Bahrâm Sâdeghi Cas d’une interférence ou d’un échange?
Authors: Arabi Atiyeh , Karimian Farzaneh
Published: February 2020

Résumé

L’étiquette de minimaliste, celle de la nouvelle tendance littéraire et artistique de la fin des années soixante-dix, réunit des auteurs aux textes brefs, qui dans un mouvement de tabula rasa, partagent certaines inclinations esthétiques. Partisans de l’art de simplicité et de l’esthétique de la concision reconnue dans l’écriture par sobriété de l’expression, réduction de la trame narrative, «atomisation de l’intrigue», absence de sens historique, de grandes idées philosophiques, personnages anonymes, etc., ces auteurs se considèrent unanimement redevables à un avant-coureur commun : Samuel Beckett. Il en va de même pour les écrivains minimalistes d’Iran qui reconnaissent ouvertement leur dette envers Bahrâm Sâdeghi dont l’œuvre, parue pendant 1957- 1972, constitue l’une des explorations les plus originales de la narrativité minimaliste, avant que le courant soit répandu au pays. Précurseur du minimalisme en Iran, ce dernier s’approprie une figure marquante de son époque tenant compte du traitement particulier qu’il inflige au personnage et du parcours que poursuit cette ombre flottante dans une intrigue basée sur rien. Ainsi nous proposons-nous, dans cette étude, de cerner les aspects littéraires du minimalisme, notamment beckettien, dans la tentative scripturale de Sâdeghi. Nous y montrerons comment Sâdeghi  a reproduit des procédés similaires dans son œuvre, notamment dans La Tranchée et les gourdes vides, en retrouvant les échos, directs/indirects, de l’écriture de Beckett chez l’auteur iranien. Les deux auteurs optent pour un processus de réforme dans lequel ils engagent leur système de littérature minimaliste afin de présenter leur position de contestation de l’ordre établi à leur manière ; une lecture comparative et intertextuelle permet de souligner leur démarche commune.  

Mots-clés : Sâdeghi, Beckett, minimalisme, échange, interférence, avant-garde.
United by Rage, Self-Loathing, and Male Supremacy: The Rise of the Incel Community
Authors: Labbaf Farshad
Published: February 2020

Since the 1990’s the internet has fundamentally transformed social relations by giving rise to cyber-communities, which have brought new kinds of polymorphous, highly personalized, and lifestyle-oriented social groups. They have also given rise to new political movements, including extremist internet groups, that can be severely detrimental to the sustainable wellbeing of society (Delanty 2018, 200). Over the past decade, a fringe internet group known as the involuntary celibates (Incels) have developed mainstream infamy for their extreme misogynistic rhetoric and reactionary anti-feminist language, which has manifested into several terrorist attacks (Olheiser, 2018). It can be argued that Incels have developed an online community centred on the desire for society to revert to absolute patriarchy that dehumanizes women as mere sexual commodities and vehemently oppose the idea of women’s empowerment and sexual liberation (Tolentino 2018). In this paper, we will be analyzing the social dynamics and methods of communication within this fringe echo-chamber, we can better determine if the values of hate, self-loathing and misogyny can facilitate deliberation and in turn constitute the Incels as a legitimate community.
“Willing Victims”: The Prevalence of Violence And Public Discourse against Indigenous Women and Girls
Authors: Johnson Cassidy
Published: February 2020

Drawing on the current research, I argue that the extensive violence against Canada's Indigenous women and girls is enabled by public discourses that rely heavily on racist stereotypes. I use Razack's theoretical framework of "gendered disposibility" and "colonial terror" as a lense for critically viewing violence against Indigenous women and girls. To demonstrate the severity of violence, evidence from the Highway of Tears cases, incidents of police abuse, and the creation of the National Inquiry into Missing and Murdered Indigenous Women and Girls are all covered.
Outing Biology: Finding a Place for the Natural Sciences in Queer Discourses
Authors: Marlow Sarah
Published: February 2020

This paper critically responds to Stacy Alaimo’s “Eluding Capture: The Science, Culture and Pleasure of Queer Animals” (2010), from Queer Ecologies by Bruce Erickson and Catrina Mortimer-Sandilands. Here, I focus on how the author addresses the relationship between social sciences and natural sciences, how social structures impact the ways in which we understand and interpret scientific data, and how she suggests we embrace the concept of “Naturecultures” in order to move forward in recognizing that heteronormative accounts of life, while dominant, are not the only possible lenses through which nature and sex can/should be seen. I explore Alaimo’s arguments against various different accounts of “same-sex” sexual activity in nature, whilst also reiterating that she does not wish to use animal sex as a form of validation for the LGBTQ+ community, reducing its mere existance to that of biological essentialism and erasing any possible discussions of gender/sexual fluidity by doing so. Instead, she cleverly uses rhetoric regarding animal sex and their perceived sexuality to expose the intrinsic heteronormativity that permeates even the supposedly “empirical” biological sciences, whilst bringing forward what I perceive as a very valuable discussion regarding how social life influences biological life, as opposed to the other way around.

The Victimization of Criminalized Women and Trauma Trails: Pathways to Criminalization and the Dichotomy of the Victim/Offender Continuum
Authors: Coughlan Georgia
Published: February 2020

This paper explores the victimization/criminalization dichotomy as women who are criminalized are often marginalized and have extensive histories of trauma; they have often experienced victimization through abuse, colonialism, familial instability, poverty, addiction, and mental health struggles. The trauma women experience further informs their life courses, and in many instances results in further victimization. The ways in which the criminal justice system and correctional institutions contribute to the victimization of women is addressed. There is no catch-all solution to the issues that contribute to the criminalization of marginalized women—many of the challenges that they face are multifaceted and systemic. Despite this, criminalized women cannot only be considered victims of circumstance, and their voices are necessary to improving the system that perpetuates their marginalization.
