Gangs, gangsters, and ganglands: towards a global comparative ethnography

Gangs occupy a key position in the global imaginary of violence, widely perceived and represented as primary sources of brutality and insecurity. This can be related to the fact that they are one of a small number of truly global phenomena, found in almost every society across both time and space. At the same time, however, as almost 100 years of gang research have highlighted, the phenomenon can vary significantly in form, dynamics, and consequences. While there have been many insightful studies of gangs, the overwhelming majority have focused on a single group or location, and we still lack a proper sense of what kinds of gang dynamics might be general, and which ones are specific to particular times and places. The GANGS project will develop a systematic comparative investigation of global gang dynamics, to better understand why they emerge, how they evolve over time, whether they are associated with particular urban configurations, how and why individuals join gangs, and what impact this has on their potential futures. It will draw on original ethnographic research carried out in multiple locations, adopting an explicitly tripartite focus on “Gangs”, “Gangsters”, and “Ganglands” in order to better explore the interplay between group, individual, and contextual factors. The first will consider the organisational dynamics of gangs, the second will focus on individual gang members and their trajectories before, during, and after their involvement in a gang, while the third will reflect on the contexts within which gangs emerge and evolve. Research will combine innovative collaborative ethnography in Nicaragua, South Africa, and France, a ground-breaking comparison of 35 individual gang member life histories from across Africa, Asia, Europe, North and South America, and unique joint ethnographic investigations into the political economy of three gang-affected cities in Nicaragua, France, and South Africa.
Vitreoretinal influences on lens function and cataract

The lens is composed of a thin metabolically active outer layer, consisting of epithelial and superficial fibre cells. Lying within this outer shell are terminally differentiated, metabolically inactive fibre cells, which are divided into an outer cortex and central nucleus. Mature fibre cells contain a very high protein concentration, which is important for the transparency and refractive power of the lens. These proteins are protected from oxidation by reducing substances, like glutathione, and by the low-oxygen environment around the lens. Glutathione reaches the mature fibre cells by diffusing from the metabolically active cells at the lens surface. With age, the cytoplasm of the nucleus becomes stiffer, reducing the rate of diffusion and making nuclear proteins more susceptible to oxidation. Low pO 2 is maintained at the posterior surface of the lens by the physical and physiological properties of the vitreous body, the gel filling the space between the lens and the retina. Destruction or degeneration of the vitreous body increases exposure of the lens to oxygen from the retina. Oxygen reaches the lens nucleus, increasing protein oxidation and aggregation and leading to nuclear cataract. We suggest that maintaining low pO 2 around the lens should prevent the formation of nuclear cataracts.
A Scalable Limited Feedback Design for Network MIMO Using Per-Cell Product Codebook

In network MIMO systems, channel state information is required at the transmitter side to multiplex users in the spatial domain. Since perfect channel knowledge is difficult to obtain in practice, limited feedback is a widely accepted solution. The dynamic number of cooperating BSs and heterogeneous path loss effects of network MIMO systems pose new challenges on limited feedback design. In this paper, we propose a scalable limited feedback design for network MIMO systems with multiple base stations, multiple users and multiple data streams for each user. We propose a limited feedback framework using per-cell product codebooks, along with a low-complexity feedback indices selection algorithm. We show that the proposed per-cell product codebook limited feedback design can asymptotically achieve the same performance as the joint-cell codebook approach. We also derive an asymptotic per-user throughput loss due to limited feedback with per-cell product codebooks. Based on that, we show that when the number of per-user feedback-bits Bk is {O}( NnTnR log2(ρgksum)), the system operates in the noise-limited regime in which the per-user throughput is {O} ( nR log2 (nRρgksum/NnT)). On the other hand, when the number of per-user feedback-bits Bk does not scale with the system SNR ρ, the system operates in the interference-limited regime where the per-user throughput is {O}(nRBk/(NnT)2). Numerical results show that the proposed design is very flexible to accommodate dynamic number of cooperating BSs and achieves much better performance compared with other baselines (such as the Givens rotation approach).
Postchemotherapy Retroperitoneal Lymph Node Dissection in Patients With Nonseminomatous Testicular Cancer: A Single Center Experiences

Testicular cancer accounts for about 1 - 1.5% of all malignancies in men. Radical orchiectomy is curative in 75% of patients with stage I disease, but advance stage with retroperitoneal lymph node involvement needs chemotherapy. All patients who have residual masses ≥ 1 cm after chemotherapy should undergo postchemotherapy retroperitoneal lymph node dissection (PC-RPLND).Treatment of advanced nonseminomatous testicular cancer is usually a combination of chemotherapy and surgery. We described our experience about postchemotherapy retroperitoneal lymph node dissection (PC-RPLND) in our center.In a retrospective cross-sectional study between 2006 and 2011, patients with a history of postchemotherapy retroperitoneal lymph node dissection (PC-RPLND) in Imam Khomeini hospital were evaluated. All patients had normal postchemotherapy serum tumor markers and primary nonseminomatous cancer. We reviewed retrospectively clinical, pathological, and surgical parameters associated with PC-RPLND in our center.Twenty-one patients underwent bilateral PC-RPLND. Mean age was 26.3 years (ranged 16 - 47). Mean size of retroperitoneal mass after chemotherapy was 7.6 cm. Mean operative time was 198 minutes (120 - 246 minutes). Mean follow-up time was 38.6 months. Pathologic review showed presence of fibrosis/necrosis, viable germ cell tumor and teratoma in 8 (38.1%), 10 (47.6%) and 3 (14.28%) patients, respectively. One patient in postoperative period of surgery and three patients in two first years after surgery were expired. Of 17 alive patients, only two (11.8%) had not retrograde ejaculation.PC-RPLND is one the major operations in the field of urology, which is associated with significant adjunctive surgeries. In appropriate cases, PC-RPLND was associated with good cancer specific survival in tertiary oncology center.

The device includes an expandable tampon made of at least one absorbent material, having a proximal portion and a distal portion, designed to collect and absorb said active liquid dispensed in the intracorporeal cavity and to expand and bear in a leak tight manner against mucous membrane of the intracorporeal cavity, and a source of liquid phase including a capsule, at least the proximal part of which is at least partially surrounded by the expandable tampon.
Congenital diffuse infiltrating facial lipomatosis

Congenital diffuse infiltrating lipomatosis of the face (CDIL-F) is a rare pathological entity belonging to the subgroup of lipomatous tumors. Till date only a handful of cases has been documented and known to occur exclusively in infancy. On microscopical examination, it is characterized by diffuse infiltration of mature adipose tissue over normal muscle fibers, rapid growth, associated osseous hyperplasia, and a high recurrence rate after surgical intervention. An attempt has been made to identify and characterize all the 49 documented cases of CDIL-F in literature along with describing a report of a male child with CDIL-F. Follow-up of 8 years has been documented. The pathogenesis and spectrum of treatment modality are discussed with identified clinical features.

Three-dimensional, one-point collision with friction

This paper deals with one-point collision with friction in three-dimensional, simple non-holonomic multibody systems. With Keller’s idea regarding the normal impulse as an independent variable during collision, and with Coulomb’s friction law, the system equations of motion reduce to five, coupled, nonlinear, first order differential equations. These equations have a singular point if sticking is reached, and their solution is ‘navigated’ through this singularity in a way leading to either sticking or sliding renewal in a uniquely defined direction. Here, two solutions are presented in connection with Newton’s, Poisson’s and Stronge’s classical collision hypotheses. One is based on numerical integration of the five equations. The other, significantly faster, replaces the integration by a recursive summation. In connection with a two-sled collision problem, close agreement between the two solutions is obtained with a few summation steps.
Automedicação entre pacientes dos ambulatórios de especialidades de uma universidade pública do estado do Rio Grande do Norte

A automedicação configura-se como um problema de saúde pública, e o uso racional pode poupar recursos nos casos de tratamento e de terapêutica para doenças menores. Segundo a OMS, metade de todos os fármacos é prescrita de forma incorreta, além de vendida e dispensada também de forma equivocada. Nesta pesquisa objetivou-se conhecer os hábitos de automedicação e fatores que influenciam essa prática, caracterizando o perfil do grupo a partir dos dados sociodemográfico, frequência, necessidade de prescrição, busca informativa, motivos e tipos de medicações em uso no contexto da automedicação entre os pacientes atendidos pelo Ambulatório da Faculdade de Ciências da Saúde (FACS) da Universidade do Estado do Rio Grande do Norte. Tratou-se de um estudo de corte transversal com abordagem qualitativa realizado com pacientes que frequentam os ambulatórios de especialidades da Universidade. A coleta deu-se por meio da realização de uma entrevista semiestruturada. O perfil dos pacientes entrevistados mostra-se majoritariamente utilizador de sintomáticos, com notoriedade para as queixas de dores gerais e cefaleia, com prevalentes de caracteres adultos, do sexo feminino, casado, procedentes da mesma cidade onde se localiza o serviço ambulatorial pesquisado. Enquadra-se em sua maior quantidade no serviço de ginecologia e obstetrícia, que se automedicam em tempos atuais, sem prescrição habilitado. Apesar do balconista de farmácia ter sido o mais mencionado como recomendado dos medicamentos, não foi, paradoxalmente, o ente mais procurado para busca de informações sobre os medicamentos. A automedicação ainda consiste em um grave dilema da saúde pública nacional e global, e seu uso indiscriminado pela população caracteriza-se deletério sob a ótica de inúmeros problemas físicos e psicossociais. Em estudos posteriores, sugere-se que o mapeamento demográfico, social, cultural e com os traços do perfil “consumístico” medicamentoso seja ampliado.
A superlotação das prisões na América Latina

Uma das consequências do crescimento da população carcerária no Brasil e em outros países latino-americanos são prisões cada vez mais abarrotadas de pessoas e com condições precárias para o cumprimento das penas. Tal realidade desencadeia uma série de outros problemas no sistema prisional, em uma espécie de efeito dominó. Nesse contexto, o presente artigo busca fazer uma análise das prisões na América Latina. O texto tem como base a doutrina sobre o tema e como objetivo abordar as más condições carcerárias e a superlotação nos ambientes prisionais de diferentes países.

A retrievable subsurface well conduit engaging apparatus having releasable engaging means which are movable outwardly to engage a well conduit and which may be released by up and down movement of an operating means. Locking means maintains the well conduit engaging means in engagement with the well conduit until the operating means is moved upwardly which releases a coupling means from the locking means and allows disengagement of the apparatus.
LAYING AND PROTECTING CABLE INTO EXISTING COVERING SURFACES

To construct an underground cable line in-situ, cut and immediately evacuate a void in the existing covering surface. Next, lay or apply cable(s) into the void. Then, flow a non-shrinking composition into a portion of the void around the cable to fill a portion of the void. Upon rigidification the cable is encased in the void by the non-shrinking composition. Last, apply a topping material to the exposed surface of the composition in such volume as to fill any remaining portion of the void.
Dual targeting of senescence and tumor immunity for cancer therapy

We have previously demonstrated that cellular senescence opposes tumorigenesis thereby opening up new potential opportunities for cancer treatment. Senescence and tumor immunity in cancer are tightly interconnected. Tumor-infiltrating immune cells promote the clearance of senescent tumor cells thereby contributing to the tumor suppressive function of senescence. Moreover, T lymphocytes can drive senescence in cancers by secreting different cytokines in the tumor microenvironment. We have also recently reported that GR1+ myeloid cells antagonize treatment-induced senescence (TIS) and that compounds that block the tumor recruitment of GR1+ cells enhance TIS. Major objective of this proposal is to characterize the immune landscape of different prostate cancer mouse models in order to develop novel treatment modalities that combine pro-senescence compounds with immunotherapy. Using proteomics and bioinformatics approaches, we will assess how the genetic background of prostate tumors, shapes the tumor microenvironment and immune response during TIS. Next, we will define the mechanisms that regulate the recruitment and activation of myeloid derived suppressive cells, macrophages and B-lymphocytes in Pten deficient prostate tumors by focusing on a novel class of secreted factors identified in these tumors. We will also assess in vivo whether the secretome of tumor cells can transmit senescence to TILs and compounds that interfere with the secretome can prevent immunosenescence. Finally, we will develop monoclonal antibodies directed towards senescent tumors cells that we will use as diagnostic and therapeutic tools. These antibodies will be used as biomarkers to detect senescent tumor cells in prostate cancers and will be tested in pre-clinical trials to assess whether they improve tumor clearance during TIS. Our findings will form the basis for future clinical trials in prostate cancer patients.
Parallelization Strategies for Local Search Algorithms on Graphics Processing Units

The purpose of this paper is to propose effective parallelization strategies for Local Search algorithms on Graphics Processing Units (GPU). We consider the distribution of the 3-opt neighborhood structure embedded in the Iterated Local Search framework. Three resulting approaches are evaluated and compared on both speedup and solution quality on a state-of-the-art Fermi GPU architecture. Solving instances of the Travelling Salesman Problem ranging from 100 to 3038 cities, we report speedups of up to 8.51 with solution quality similar to the best known sequential implementations and of up to 45.40 with a variable increase in tour length. The proposed experimental study highlights the influence of the pivoting rule, neighborhood size and parallelization granularity on the obtained level of perfor-
An improved hashing based password security scheme using salting and differential masking

In this era of digitization, the foremost requirement is information security which is normally secured by some authentication process. Password security is a major issue for any authenticating process and different researches in past have proposed different techniques like hashing, salting, honeywords to make the process most secured. Here, we propose a new technique which involves hashing, then salting and a crash list generation formed by differential masking process. The crash list for any user is stored in the password file. Any security breach with the password file can lead to login attempts by hacker using one of these passwords from the list. An attempt to log in using any of these crash list words raises an alarm for the application and the application can block that user or address. This process performs a unique hashing algorithm with very low time complexity as most of the steps involved simple binary operations.
Vaccine development against variable pathogens

Vaccination is the most effective strategy to prevent infectious diseases but despite years of research there are no vaccines against variable pathogens such as HIV-1. Contrary to what is required for non-variable pathogens, vaccines against genetically variable pathogens need to elicit antibodies specific for conserved epitopes to protect against the majority of strains. These antibodies are termed broadly neutralizing antibodies (bNAbs). bNAbs against the genetically variable HIV-1 surface protein Env are highly somatically mutated and develop in a fraction of infected individuals, but have thus far failed to be elicited by vaccination. For a vaccine to elicit antibodies against a specific epitope of a variable pathogen, it needs to specifically expand rare precursor cells in the presence of a polyclonal B cell response that bind other parts of the same antigen. Furthermore, it needs to guide the rare precursor cells through repeated germinal center reactions to induce high numbers of somatic mutations, a critical characteristic for the potency of HIV-1 bNAbs. To develop such vaccines, we need to understand the regulation of antigen-driven affinity maturation of B cells in a polyclonal immune system in response to complex antigens. To study this, we will perform immunization experiments of wild type mice, adoptively transferred to include a limited pool of naïve B cells from novel HIV-1 Env-specific human antibody knock-in mice. In contrast to conventional antibody knock-in mice that have been used to study B cell activation previously, naïve precursor B cells from these knock-in mice are specific for a complex pathogen-derived antigen. Detailed characterization of the immune responses that develop in response to Env- and non-Env-based antigens, will enable us to generate vaccines that more efficiently drive protective immune responses against variable pathogens such as HIV-1 and Influenza, as well as potential emerging diseases.
Sustainable approach to cultural Heritage for the urban Areas Requalification in Europe

The diversity of the cultural heritage assets, ranging from museums, to buildings to archives, to cultural itineraries and events, is a cornerstone in European identity and a catalyst for social inclusion. It also plays a specific role in achieving the Europe 2020 strategy goals for a smart, sustainable and inclusive growth, given its relevance not only in culture, but also in social and economic development, cohesion, education, tourism and innovation. However, pressure applied by visitors and residents means that heritage professionals, institutions and stakeholders face growing challenges to keep cultural assets and the territory around it protected, enhanced and, at the same time, accessible to all. SHARE aims at exchanging experiences in cultural heritage policies in urban settings, in order to identify best practices and innovative methods to develop a sustainable and smart approach to its management and use. The project will target ways in which smart cities projects can be effectively improved by including a smart and sustainable agenda for cultural assets in urban centers. The exchange of experience method will be based on a review of existing policy tools, European policy outlines and best practices and will include specific researches to be carried out in each partner’s area. The result of the interregional exchange process, lasting 24 months during Phase 1 of the project, will be conveyed in 6 Action Plans, that will indicate ways to successfully transfer of SHARE’s outputs into mainstream policies, with particular reference to 4 ERDF funds. The partners represent a variety of public bodies, agencies and academic centers coming from 7 Countries across Europe dealing with cultural heritage and smart cities policies and will commit to effectively share results of the project with local stakeholders groups and the MAs and institutions implementing local policies, and to ensure monitoring of the Action Plans over the 2-years period Phase 2 of the project.
A Concise History of Chinese Psychology of Religion

The history of religious thought and the history of human thought are closely interrelated, so the study of Chinese psychology of religion should pay attention to the study of Chinese history. In this paper, we summarize the history of Han Chinese psychology of religion in three stages from the perspectives of the history of Chinese thought, the history of Chinese religion, and the history of Chinese psychology. In the accumulation stage during the Spring and Autumn and Warring States periods, debates about “human nature” were central to a psychology of religion. We hope that this will be helpful for the further study of Chinese psychology of religion.
Grounding of Primary System for LV Networks

Secondary or low-voltage (LV) networks are applied in many large cities throughout the U.S., and in some other countries. Various grounding schemes have been employed for the primary systems supplying these secondary networks. In this paper, characteristics of the different grounding schemes for the substation and primary feeders that supply the LV networks are reviewed. The impacts of primary system grounding on the ground fault currents, the unfaulted line-to-ground voltages, as well as the voltage sags in the LV network have been considered for the single line-to-ground fault on the primary. The differences between systems with network transformers having the delta- or grounded-wye-connected primary windings are discussed. The relationships between grounding characteristics and protection settings, including actual examples, have been documented.
