Neoliberal Riskscapes and Preemptive Poetics in Orly Castel-Bloom’sDolly City
Authors: Alon Shir
Published: February 2019

Focusing on Hebrew writer Orly Castel-Bloom’s novel Dolly City (1993), as well as on her short stories published in the same period, this essay analyzes how neoliberal principles of risk management, primarily risk privatization and speculation, shape postmodernist literary genres and techniques. It argues that Dolly City reflects, thematically and formally, a shift between two biopolitical models of governance: from a welfare model based on a calculable and statistical futurity and on communal sacrifice, to a neoliberal model grounded in a speculative futurity and a zero-risk principle of preemption. Dr. Dolly, the narrator of the novel, who suffers from the neoliberal “illness of improbable possibilities,” applies this preemptive principle to language itself, creating what this essay defines as “preemptive poetics:” a literalized and material approach to language that protects it from the infinite improbable possibilities of figurative expression. Dolly City traces the postmodernist problem of the destabilized text, detached from any knowable intention, to neoliberal political-economic principles of risk management.
The Rhythm of Unity: Irène Némirovsky’sSuite françaiseand Leo Tolstoy’sWar and Peace
Authors: Cenedese Marta Laura
Published: February 2019

Published in 2004, Irène Némirovsky’s Suite française is a historical novel set during the French debacle and the German Occupation of France (1940–42). Scholars have studied it in relation to other French novels that touch upon similar issues; however, little attention has been given to its literary sources and to Némirovsky’s creative process. This article fills this gap by presenting an analysis of the relation between Suite française and Leo Tolstoy’s War and Peace. It will also show the “creative influence” of the Russian master on Némirovsky, addressing how Suite française engages creatively with War and Peace and its reception. Building on archival material and close textual analysis, the article unravels the complex relation between the two novels by exploring questions of structure, the connections between history and fiction, and the use of music as a literary tool.
Splitting the Colonizer: Discarding Centrality as Freedom
Authors: Morales Rafael Acosta
Published: February 2019

This article explores a divide between the affective effects of freedom as a political core concept and its discursive articulation. It analyzes the failure of a Hegelian discourse of freedom that is often articulated in relation to colonial relationships. Departing from the idea of the life-and-death struggle in dialectical thought, the article argues for a different goal for postcolonial thought than dialectic unity as promised in Hegelian philosophy, examining the position of four writers: Alfonso Reyes, Mário de Andrade, F. Scott Fitzgerald, and Ngũgĩ wa Thiong’o. The essay concludes that freedom is not as desirable a political goal as it would appear. First, while logically it is fairly easy to distinguish freedom from coercion, the freedom of self-mastery, and, ultimately, the freedom to impose our own world upon others, affectively, these concepts are in fact often conflated. Second, as Fitzgerald’s The Great Gatsby demonstrates, the promise of dialectic unity is unattainable not only for the colonized or oppressed; it is also beyond the reach of the oppressor. Through the study of other postcolonial authors, the article proposes certain lines of inquiry through which split consciousnesses may offer political alternatives to the use of freedom as a political goal.
CRISPR babies: a view from the centre of the storm
Authors: Lovell-Badge Robin
Published: February 2019

Towards the end of November 2018, news broke that the Chinese researcher He Jiankui had created the world's first genome-edited babies. This came shortly before the start of the Second International Summit on Human Genome Editing, where researchers, ethicists and others concerned with regulation, social issues and public engagement from around the world gathered to discuss the latest advances in the field. In this Spotlight, I provide my perspective on the events that occurred shortly prior to and at the summit, where He Jiankui gave an account of his activities. I also discuss what was wrong with his approach and how, after more research and with appropriate regulation, clinical applications of germline genome editing in humans may be justifiable.
Navigation and the developing brain
Authors: Newcombe Nora S.
Published: February 2019

As babies rapidly acquire motor skills that give them increasingly independent and wide-ranging access to the environment over the first two years of human life, they decrease their reliance on habit systems for spatial localization, switching to their emerging inertial navigation system and to allocentric frameworks. Initial place learning is evident towards the end of the period. From 3 to 10 years, children calibrate their ability to encode various sources of spatial information (inertial information, geometric cues, beacons, proximal landmarks and distal landmarks) and begin to combine cues, both within and across systems. Geometric cues are important, but do not constitute an innate and encapsulated module. In addition, from 3 to 10 years, children build the capacity to think about frames of reference different from their current one (i.e. to perform perspective taking). By around 12 years, we see adult-level performance and adult patterns of individual differences on cognitive mapping tasks requiring the integration of vista views of space into environmental space. These lines of development are continuous rather than stage-like. Spatial development builds on important beginnings in the neural systems of newborns, but changes in experience-expectant ways with motor development, action in the world and success–failure feedback. Human systems for integrating and manipulating spatial information also benefit from symbolic capacities and technological inventions.

Published: February 2019

Place recognition is a complex process involving idiothetic and allothetic information. In mammals, evidence suggests that visual information stemming from the temporal and parietal cortical areas (‘what’ and ‘where’ information) is merged at the level of the entorhinal cortex (EC) to build a compact code of a place. Local views extracted from specific feature points can provide information important for view cells (in primates) and place cells (in rodents) even when the environment changes dramatically. Robotics experiments using conjunctive cells merging ‘what’ and ‘where’ information related to different local views show their important role for obtaining place cells with strong generalization capabilities. This convergence of information may also explain the formation of grid cells in the medial EC if we suppose that: (1) path integration information is computed outside the EC, (2) this information is compressed at the level of the EC owing to projection (which follows a modulo principle) of cortical activities associated with discretized vector fields representing angles and/or path integration, and (3) conjunctive cells merge the projections of different modalities to build grid cell activities. Applying modulo projection to visual information allows an interesting compression of information and could explain more recent results on grid cells related to visual exploration. In conclusion, the EC could be dedicated to the build-up of a robust yet compact code of cortical activity whereas the hippocampus proper recognizes these complex codes and learns to predict the transition from one state to another.
The potential of virtual reality for spatial navigation research across the adult lifespan
Authors: Diersch Nadine , Wolbers Thomas
Published: February 2019

Older adults often experience serious problems in spatial navigation, and alterations in underlying brain structures are among the first indicators for a progression to neurodegenerative diseases. Studies investigating the neural mechanisms of spatial navigation and its changes across the adult lifespan are increasingly using virtual reality (VR) paradigms. VR offers major benefits in terms of ecological validity, experimental control and options to track behavioral responses. However, navigation in the real world differs from navigation in VR in several aspects. In addition, the importance of body-based or visual cues for navigation varies between animal species. Incongruences between sensory and motor input in VR might consequently affect their performance to a different degree. After discussing the specifics of using VR in spatial navigation research across species, we outline several challenges when investigating age-related deficits in spatial navigation with the help of VR. In addition, we discuss ways to reduce their impact, together with the possibilities VR offers for improving navigational abilities in older adults.
The internal maps of insects
Authors: Webb Barbara
Published: February 2019

Insect navigation is strikingly geometric. Many species use path integration to maintain an accurate estimate of their distance and direction (a vector) to their nest and can store the vector information for multiple salient locations in the world, such as food sources, in a common coordinate system. Insects can also use remembered views of the terrain around salient locations or along travelled routes to guide return, which is a fundamentally geometric process. Recent modelling of these abilities shows convergence on a small set of algorithms and assumptions that appear sufficient to account for a wide range of behavioural data. Notably, this ‘base model’ does not include any significant topological knowledge: the insect does not need to recover the information (implicit in their vector memory) about the relationships between salient places; nor to maintain any connectedness or ordering information between view memories; nor to form any associations between views and vectors. However, there remains some experimental evidence not fully explained by this base model that may point towards the existence of a more complex or integrated mental map in insects.

Published: February 2019

Introduction

Cancer cachexia is characterized by loss of muscle mass and function. Increased protein catabolism, inflammation, impaired anabolism, and mitochondrial function markedly contribute to the pathogenesis of this syndrome. Physical activity has been suggested as a useful tool to prevent or at least delay the onset and progression of cancer-induced muscle wasting. Two main types of exercise can be adopted, namely, resistance and endurance training. The present study is aimed to investigate the effectiveness of a combined (resistance + endurance) exercise protocol in preventing/reverting cancer-induced muscle wasting.

Methods

Mice bearing the C26 colon carcinoma have been used as a model of cancer cachexia. They have been exposed to combined exercise training during 6 wk (4 before tumor implantation, 2 during tumor growth). Climbing a 1-m ladder inclined at 85° has been used for resistance training, while aerobic (endurance) exercise has been carried out on the same day using a motorized wheel.

Results

In C26-bearing mice, both muscle mass and strength are improved by combined training, while just the latter increased in exercised healthy animals. Such a pattern is associated with modulations of two markers of autophagy, namely, LC3B-I/II ratio, increased in sedentary tumor hosts and reduced in exercised C26-bearing mice, and p62, steadily increased in both sedentary and trained tumor-bearing animals. Finally, combined training is not able to modify PGC-1α protein levels, but it improves succinate dehydrogenase activity, both reduced in the muscle of the C26 hosts.

Conclusion

The data reported in the present study show that combined training improves muscle mass and function in the C26 hosts, likely modulating autophagy and improving mitochondrial function; these observations suggest that combined exercise might become part of a multimodal approach to treat cancer cachexia.
Ovarian remnant syndrome after laparoscopic ovariectomy in a cat
Authors: Properzi R. , Boschi P. , Leonardi F.
Published: February 2019

The first case of accidental implantation of ovarian tissue at the port site after laparoscopic ovariectomy in a cat was described. A 2-year-old, spayed female, domestic cat showed recurrent behavioral oestrus signs (vocalization, increased playfulness, and lordosis) four months after laparoscopic ovariectomy. Abdominal ultrasound revealed bilateral endometrial hyperplasia and an inhomogeneous mass attached to the abdominal wall at the port site of previous laparoscopic ovariectomy. Ovarian remnant syndrome was supposed. Diagnostic laparoscopy confirmed the presence of a mass that was 2 cm in diameter and macroscopically similar to ovarian tissue. Laparoscopy was converted to laparotomy to remove the abnormal tissue and the uterus. Histopathological findings showed follicles of various maturation stages in the mass, and confirmed endometrial hyperplasia. Histology underscored that ovarian remnant tissue resumed function. No clinical signs consistent with ovarian remnant syndrome were reported six months after removal of the abnormal tissue. In conclusion, removal of the ovaries through the laparoscopic port site may cause fortuitous ovarian tissue implantation at the abdominal wall in the cat.

Published: February 2019

This Research Paper addresses the hypothesis whether in dairy ewes: periparturient β-hydroxybutyric acid (BHBA) and non-esterified fatty acids (NEFA) concentrations are associated with milk yield, composition and udder halves with increased somatic cell counts (SCC ≥ 0.5 × 106 cells/mL). A total of 186 Chios ewes reared under intensive system were used for this research. Serum BHBA and NEFA concentrations were measured before lambing (-30d,  -15d), and BHBA concentrations after lambing (+7d, +15d, +30d, +45d). Milk samples were collected at 15, 30 and 45days in milk (DIM). Total milk yield (MY) of the first 30, 60 and 90 DIM and total fortnightly milk yield (FMY) produced from 15 to 59 DIM were recorded. Positive associations between BHBA at +7d and MY of the first 30, 60 and 90 DIM were revealed (P < 0.001). For every increased unit of BHBA at +15d, +30d and +45d, FMY was decreased (DIM: 15 – 29 and 30 – 44) (P = 0.001 and P = 0.015, respectively) or increased (DIM: 45 – 59) (P < 0.001). BHBA before lambing (-30d, -15d) affected the number of halves presented SCC ≥ 0.5 × 106 cells/mL at 15 and 30 DIM (P = 0.011, P = 0.014, P = 0.009, P = 0.096, respectively). Finally, for every increased unit of BHBA during lactation (+15d, +30d, +45d) a decrease in the concentration of milk in proteins, solids not fat and lactose was noted (P < 0.001). This work demonstrates the associations of periparturient blood biochemical parameters (BHBA, NEFA) with milk yield and specific milk production characteristics.

Mycoplasma bovis infection in grazing dairy cows has not been reported in the Republic of Serbia to date. It is important to monitor its seroprevalence on the field. The presence of specific antibodies against M. bovis in the blood serum of grazing dairy cows is investigated in the present study. A total of 131 blood serum samples of clinically healthy dairy cows were examined. Sampling was performed during 2013 from five different areas in Serbia: Zasavica, Pozarevac, Gruza, Novi Sad and Banatski Karlovac. A commercial ELISA kit for diagnosis of M. bovis antibodies in blood serum samples, manufactured by Bio-X Diagnostics, Belgium, was used. Specific antibodies against M. bovis were identified in 13 out of 131 samples (9.92%) from 4 locations; the only negative location was the most southern Gruza. The revealed seroprevalence is evidence for the presence of M. bovis in grazing dairy cows in different locations of Serbia.

The term gut health is currently becoming more important for domestic animals including poultry. Gut health refers to the fundamental organ system which covers multiple positive functions like effective digestion, stabilizing intestinal microbiota, gut pH and modulation of effective immune response. Gut health depends on proper balance of microbial population. A wide range of feed and pathogen associated factors influence this balance, and adversely affect the animal health status and production performance. Antibiotic stimulators have been used in farm animals to achieve maximum production. But drug resistance and residual effects of antibiotics in animal products (milk, meat and egg etc.) have raised serious issues in human life. Therefore, The European Union (EU) has strictly banned the application of antibiotic stimulators in livestock nutrition in several others countries including China. As a result, an alternative to antibiotic growth promoters are required to support the profitable and sustainable animal production system. Probiotics as nutraceuticals has been categorized as an alternative natural feed supplement for commercial utilization. Such products have been recognized as safe feed additives in animal industry. Very few studies have comparatively described the effect of probiotics on gut health of domestic animals. Therefore, the aim of this review is not only to explore the beneficial effects of probiotics in improving gut health of domestic animals as an alternative to antibiotic growth promoters, but also to evaluate the probiotics associated health and risk factors, and to provide comprehensive scientific information for researchers, scientists and commercial producers.

Published: February 2019

Iodine is an essential trace element for humans and animals. The incidence of iodine poisoning in cattle is low. In the present study, we evaluated the clinical findings, serum glucose and cholesterol, thyroid hormone and urine iodine levels in cattle exposed to excess iodine. All of the clinical data were determined following the addition of potassium iodide to the drinking water. Inappetence, cough, and hyperthermia were notable clinical findings. We detected a very high iodine level (470 μg /L) in an analysis of the drinking water samples. A biochemical analysis revealed that the serum cholesterol levels in the affected cattle were significantly lower (p<0.05) than in healthy cattle. However, the serum glucose in the affected cattle was significantly higher (p<0.05) compared to healthy cattle. The iodine concentration in the urine of the affected animals was also significantly higher (p<0.05) than in the healthy animals. Importantly, a hematological analysis indicated leukocytosis with neutrophilia. Several clinical signs, including hyperthermia, tachycardia, alopecia, and a naso-oral discharge, based on suspected history can suggest iodine intoxication. In addition, biochemical parameters, such as urine iodine, serum glucose and cholesterol levels, were observed to be different between healthy and affected cattle. The thyroid function in affected cattle should also be studied.
First report of Angiostrongylus vasorum in red foxes (Vulpes vulpes) in Serbia
Authors: Gavrilović P. , Todorović I. , Pavlović I. , Živulj A.
Published: February 2019

Angiostrongylosis caused by Angiostrongylus vasorum is an emerging disease in Europe and the red fox (Vulpes vulpes) is considered as a main reservoir species for this parasite. Since there have been no reports of A. vasorum in red foxes in Serbia at the time of carrying out our investigations, the aim of the investigations was to explore the role of red foxes in South Banat (northern Serbia) as reservoirs for A. vasorum. Legally hunted foxes were autopsied in the Veterinary Specialised Institute “Pančevo”. The heart, lungs and pulmonary artery were examined macroscopically for evidence of gross lesions and for the presence of adult specimens of A. vasorum. Impression smears of the changed lung tissue were examined microscopically for the presence of first stage larvae of A. vasorum and histopathological examination was performed on lung samples. Out of 24 examined foxes hunted in different locations, 13 had lesions manifested in the lungs, which were suspected to be indicative of angiostrongylosis. In the majority of the foxes distal parts of the pulmonary lobes were swollen, firm, and discoloured to dark-red, dark-yellow and darkbrown. The characteristic lesions in distal parts of the pulmonary lobes were completely consistent with the presence of adult parasites in the right heart and pulmonary arteries, and with the presence of the first stage larvae in the impression smears. The present finding contributes to the knowledge of geographic distribution of angiostrongylosis in red foxes in Europe and provides valuable information that should raise awareness in veterinarians to consider this parasitosis in dogs with signs of cardiopulmonary diseases.
MUC1 and E-cadherin immunohistochemistry of endometrium cannot predict the outcome of in vitro fertilization: A case-control study
Authors: Chakravarty Saumitra , Kamal Mohammed
Published: February 2019

Background:Althoughin vitrofertilization (IVF) has played a major role in the management of infertility, its failure rate is still 60-80% and most of the causes failure are unknown. Therefore, a histomorphology-based predictive tool to forecast IVF outcome that utilizes expression data of certain cellular adhesion molecules in endometrium pertaining to successful implantation might provide the theoretical basis to develop a low-cost laboratory investigation suited for low to middle income countries as opposed to the expensive gene expression based tools like endometrial receptivity array. In this study, mucin 1 (MUC1) and E-cadherin immunohistochemistry of endometrium from aspiring IVF women were analyzed to see if there is any correlation between signal intensities and endometrial receptivity in terms of IVF outcome.

Methods:This was a case-control study conducted among women of reproductive age with infertility who underwent IVF at the Centre for Assisted Reproduction (CARe), Dhaka between March and December 2017. Endometrial biopsy samples were collected and routine histological as well as immunohistochemical analysis was performed on those samples at the Department of Pathology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka. A total of 21 patients, 17 cases (IVF failure) and four controls (IVF success), were included in the study by consecutive convenient sampling. Relevant history and medical records of each of the patients were also obtained accordingly.

Results:No statistically significant correlation was found between IVF outcomes and the signal intensities in endometrium produced by MUC1 and E-cadherin immunohistochemistry.

Conclusions:Despite the fact that this study did not find any statistically significant correlation between endometrial immunohistochemistry of MUC1 and E-cadherin and IVF outcome, further studies may incorporate gene expression arrays to supplement or revise those findings.

The article discusses a quite new sphere of management which response for creating a corporative informational environment. Communication management is investigated in this case as the development of a complex of strategically necessary measures and processes directed both inside and outside the company. Analyzing the features of communication management in modern conditions, the authors focus their attention on the information and analytical aspect of communication management, which allows to realize its objectives and goals. Information is intended to serve the interests of the organization, employees must be able to analyze it in order to avoid over-saturation, and also to determine its authenticity. Creating a favorable communication climate, and in the wake of this, and effective information exchange strategies inside and outside the company is possible only if the following conditions are met: knowledge of the overall structure of the organization’s communication management processes, clear formulation of corporate values and goals, establishment of information exchange channels within the organization, serious analyzing the requests of various groups of consumers and creating an adequate “answer”. In general, effective communication management in the context of information culture seems to be a necessary tool for creating a competitive advantage of an organization on the modern market.

Dynamic Pricing of Wireless Internet Based on Usage and Stochastically Changing Capacity
Authors: Batur Demet , Ryan Jennifer K. , Zhao Zhongyuan , Vuran Mehmet C.
Published: February 2019

Problem definition: Inspired by new developments in dynamic spectrum access, we study the dynamic pricing of wireless Internet access when demand and capacity (bandwidth) are stochastic. Academic/practical relevance: The demand for wireless Internet access has increased enormously. However, the spectrum available to wireless service providers is limited. The industry has, thus, altered conventional license-based spectrum access policies through unlicensed spectrum operations. The additional spectrum obtained through these operations has stochastic capacity. Thus, the pricing of this service by the service provider has novel challenges. The problem considered in this paper is, therefore, of high practical relevance and new to the academic literature. Methodology: We study this pricing problem using a Markov decision process model in which customers are posted dynamic prices based on their bandwidth requirement and the available capacity. Results: We characterize the structure of the optimal pricing policy as a function of the system state and of the input parameters. Because it is impossible to solve this problem for practically large state spaces, we propose a heuristic dynamic pricing policy that performs very well, particularly when the ratio of capacity to demand rate is low. Managerial implications: We demonstrate the value of using a dynamic heuristic pricing policy compared with the myopic and optimal static policies. The previous literature has studied similar systems with fixed capacity and has characterized conditions under which myopic policies perform well. In contrast, our setting has dynamic (stochastic) capacity, and we find that identifying good state-dependent heuristic pricing policies is of greater importance. Our heuristic policy is computationally more tractable and easier to implement than the optimal dynamic and static pricing policies. It also provides a significant performance improvement relative to the myopic and optimal static policies when capacity is scarce, a condition that holds for the practical setting that motivated this research.
Dynamic Pricing of Omnichannel Inventories
Authors: Harsha Pavithra , Subramanian Shivaram , Uichanco Joline
Published: February 2019

Omnichannel retail refers to a seamless integration of an e-commerce channel and a network of brick-and-mortar stores. An example is cross-channel fulfillment, which allows a store to fulfill online orders in any location. Another is price transparency, which allows customers to compare the online price with store prices. This paper studies a new and widespread problem resulting from omnichannel retail: price optimization in the presence of cross-channel interactions in demand and supply, where cross-channel fulfillment is exogenous. We propose two pricing policies that are based on the idea of “partitions” to the store inventory that approximate how this shared resource will be utilized. These policies are practical because they rely on solving computationally tractable mixed integer programs that can accept various business and pricing rules. In extensive simulation experiments, they achieve a small optimality gap relative to theoretical upper bounds on the optimal expected profit. The good observed performance of our pricing policies results from managing substitutive channel demands in accordance with partitions that rebalance inventory in the network. A proprietary implementation of the analytics is commercially available as part of the IBM Commerce markdown price solution. The system results in an estimated 13.7% increase in clearance-period revenue based on causal model analysis of the data from a pilot implementation for clearance pricing at a large U.S. retailer.

Optimal Retail Location: Empirical Methodology and Application to Practice
Authors: Glaeser Chloe Kim , Fisher Marshall , Su Xuanming
Published: February 2019

We empirically study the spatiotemporal location problem motivated by an online retailer that uses the Buy-Online-Pick-Up-In-Store fulfillment method. Customers pick up their orders from trucks parked at specific locations on specific days, and the retailer’s problem is to determine where and when these pickups occur. Customer demand is influenced by the convenience of pickup locations and days. We combine demographic and economic data, business location data, and the retailer’s historical sales and operations data to predict demand at potential locations. We introduce a novel procedure that combines machine learning and econometric techniques. First, we use a fixed effects regression to estimate spatial and temporal cannibalization effects. Then, we use a random forests algorithm to predict demand when a particular location operates in isolation. Based on the predicted demand and cannibalization effects, we solve the spatiotemporal integer program using a quadratic program relaxation to find the optimal pickup location configuration and schedule. We estimate a revenue increase of at least 51% from the improved location configuration and schedule.

Kita dapat menyaksikan banyaknya tindak kriminalitas ataupun kenakalankenakalan reamaja yang ada disekitar kita. Remaja saat ini banyak menirukan tindakan–tindakan yang tidak pantas yang ada di internet maupun media lainnya. Kebanyakan anak-anak maupun remaja kurang memiliki bentang yang kuat dalam diri mereka untuk membentengi diri dari pengaruh dunia luar. Di Dusun Krapyak Wetan yang merupakan perbatasan daerah kota dengan desa dimana msyarakatnya sudah heterogen menimbulkan banyak masuknya budaya dari luar ke Dusun Krapyak Wetan.
