A design and implementation methodology for high variety electronics assembly systems

Small indigenous manufacturers of electronic equipment are coming under increasingly severe pressure to adopt a strong defensive position against large multinational and Far Eastern companies. A common response to this threat has been for these firms to adopt a 'market driven' business strategy based on quality and customer service, rather than a 'technology led' strategy which uses technical specification and price to compete. To successfully implement this type of strategy there is a need for production systems to be redesigned to suit the new demands of marketing. Increased range and fast response require economy of scope rather t ban economy or scale while the organisation's culture must promote quality and process consciousness. This paper describes the 'Modular Assembly Cascade' concept which addresses these needs by applying the principles of flexible manufacturing (FMS) and just in time (,JlT) to electronics assembly. A methodology for executing the concept is also outlined. This is called DRAMA (Design Houtirw !'or· Adopting Modular Assembly).

Reactive stalking:a new perspective on victimisation

Although much has been learnt about the psychological and physical harm caused to victims of stalking and cyberstalking, relatively little is known about the impact of stalking on social behaviour and relationships. This paper argues that victims of stalking sometimes go on to employ stalking behaviours against others. Although often arising from an instinctive need for self-protection, such reactive stalking can be defensive or offensive in nature. Those who engage in such behaviour may do so from a need to assert control over their lives, or from fear of further victimisation. In pursuing this argument, a case study is used to illustrate the behaviours described. The case study focuses on the experiences of three stalking victims and describes attempts to victimise the author during his research. The article also discusses some of the implications of reactive stalking for the criminal justice system and the way in which victims receive support.

Structure of glassy GeO2

The full set of partial structure factors for glassy germania, or GeO2, were accurately measured by using the method of isotopic substitution in neutron diffraction in order to elucidate the nature of the pair correlations for this archetypal strong glass former. The results show that the basic tetrahedral Ge(O-1/2)(4) building blocks share corners with a mean inter-tetrahedral Ge-O-Ge bond angle of 132(2)degrees. The topological and chemical ordering in the resultant network displays two characteristic length scales at distances greater than the nearest neighbour. One of these describes the intermediate range order, and manifests itself by the appearance of a first sharp diffraction peak in the measured diffraction patterns at a scattering vector k(FSDP) approximate to 1.53 angstrom(-1), while the other describes so-called extended range order, and is associated with the principal peak at k(PP) = 2.66( 1) angstrom(-1). We find that there is an interplay between the relative importance of the ordering on these length scales for tetrahedral network forming glasses that is dominated by the extended range ordering with increasing glass fragility. The measured partial structure factors for glassy GeO2 are used to reproduce the total structure factor measured by using high energy x-ray diffraction and the experimental results are also compared to those obtained by using classical and first principles molecular dynamics simulations.

Numerical solution of parabolic Cauchy problems in planar corner domains

An iterative method for the parabolic Cauchy problem in planar domains having a finite number of corners is implemented based on boundary integral equations. At each iteration, mixed well-posed problems are solved for the same parabolic operator. The presence of corner points renders singularities of the solutions to these mixed problems, and this is handled with the use of weight functions together with, in the numerical implementation, mesh grading near the corners. The mixed problems are reformulated in terms of boundary integrals obtained via discretization of the time-derivative to obtain an elliptic system of partial differential equations. To numerically solve these integral equations a Nyström method with super-algebraic convergence order is employed. Numerical results are presented showing the feasibility of the proposed approach. © 2014 IMACS.

Biosynthesis and analysis of plant oxylipins

The term oxylipin is applied to the generation of oxygenated products of polyunsaturated fatty acids that can arise either through non-enzymatic or enzymatic processes generating a complex array of products, including alcohols, aldehydes, ketones, acids and hydrocarbon gases. The biosynthetic origin of these products has revealed an array of enzymes involved in their formation and more recently a radical pathway. These include lipoxygenases and α-dioxygenase that insert both oxygen atoms in to the acyl chain to initiate the pathways, to specialised P450 monooxygenases that are responsible for their downstream processing. This latter group include enzymes at the branch points such as allene oxide synthase, leading to jasmonate signalling, hydroperoxide lyase, responsible for generating pathogen/pest defensive volatiles and divinyl ether synthases and peroxygenases involved in the formation of antimicrobial compounds. The complexity of the products generated raises significant challenges for their rapid identification and quantification using metabolic screening methods. Here the current developments in oxylipin metabolism are reviewed together with the emerging technologies required to expand this important field of research that underpins advances in plant-pest/pathogen interactions.

Manipulatív marketing: fogyasztói észlelések és reakciók

A marketing koncepciónak kezdetektől fogva a vevőorientáció az egyik kulcsfogalma. Tulajdonképpen annak a szemléletváltásnak köszönheti felemelkedését és más menedzsmentdiszciplínától való elhatárolását is, amellyel a vevői igényeket helyezte a vállalati gondolkodás középpontjába. Későbbiekben azonban a kutatók rájöttek arra, hogy maguk az igények az üzleti gyakorlat során nagymértékben kontrollálhatók, és az eladói oldal azóta is él ezekkel a lehetőségekkel. A kutatás arra volt kíváncsi, hogy a vállalatok manipulációs gyakorlata hogyan csapódik le a fogyasztókban, melyek azok a manipulációs eszközök, amelyeket észlelnek, és azokra milyen válaszreakciókat adnak. Azonosíthatók-e tipikus gondolkodási sémák, magatartási mintázatok, amelyek jól jellemzik egyes vevők viszonyát a vállalati manipulációval. A tanulmány feltáró interjúkra épít, amely segít megérteni a fogyasztókban végbe menő komplex mechanizmusokat. Az eredmények azt sugallják, hogy kétfajta folyamat játszódik le a vevői oldalon Egyrészt a fogyasztók idővel rutinszerű magatartásmintákat vesznek fel, amely során a manipulációs eszközök érvényesülése nem tudatos, és a vállalatoknak kedvező reakciókat vált ki. Másrészt, a fogyasztói társadalom is egyfajta érési folyamaton megy át, aminek hatására megtanulják a vállalatok gondolkodásmódját, és – bár a kognitív korlátok miatt azokat nem tudják teljes mértékben lekövetni – igyekeznek önvédő heurisztikákat beépíteni a követett magatartásukba. A kutatás alapján hipotetikusan öt vevőtípust azonosítottunk, akiket egymástól eltérő reakciók jellemeznek. Customer orientation has been the key concept of marketing since the beginning. As a matter of fact, the emergence of marketing and the conceptual distinction between marketing and the related management disciplines can be attributed to this new approach, which put customer needs in the focus of company attention. Later, researchers revealed that the needs themselves can be controlled to a greater extent and sellers have been taking advantage of it since then. The main focus of the research concentrated on the effects of manipulation practices of companies on consumers, which manipulation tools are recognised and how consumers react to them. Furthermore the research also investigated whether typical cognitive, emotional and behavioural patterns, which reflect the relationship between consumers and the manipulation practices of companies, can be identified. The study relies on explorative interviews, which help understand the complex mechanisms of consumer attitudes. The results indicates that the opposite process occur on the consumer side. On the one hand, consumers tend to follow behavioural routines after a while, which help manipulation tools work in an unconscious way that triggers reactions for the favour of companies. On the other hand, the generations of consumers are getting more and more mature and learning the companies’ mentality and, despite having cognitive limitations to identify all the tricks and deceptive attempts, they try to develop and follow defensive heuristics. Based on the data explored we identified five customer types and we described their diverse reactions to manipulation.

Without women: Masculinities, gay male sexual culture and sexual behaviors in Miami, Florida

Recent studies have reported alarmingly high rates of HIV infection and risky sexual behaviors among gay men in Miami, Florida. Previous research has suggested that the risky sexual behaviors of many gay men reflect the pursuit of intimacy and love, and that barriers to intimate relationships among gay men may stem from traditional masculinity norms. This dissertation examines the meanings which gay men ascribe to their sexual behaviors, as well as the intersections of those meanings with both traditional masculinity constructions and Miami's gay male sexual culture. ^ The study is based upon participant observation, print media content analysis, surveys and ethnographic interviews of a purposive snowball sample of 30 Cuban American, Puerto Rican, African American and Anglo gay men who reside in Miami-Dade County, Florida. Analysis of research questions was accomplished through grounded theory methods and descriptive and non-parametric statistics, including Pearson chi-square, Fisher's Exact and Mann-Whitney U tests. ^ The study shows that culturally-specified masculinity norms vary in the relative importance ascribed to heterosexual prowess, economic providership and competitiveness. These cultural differences appear important not only to the timing of sexual awareness and to the strength of homosexual stereotyping as effeminacy, but also to men's strategies in coming out as gay. The meanings men attributed to their sexual behaviors were, however, constructed in response to both inherited masculinity norms and the hypermasculine structure of Miami's gay male sexual culture. In addition to providing an ethnographic account of this subculture, the study elaborates men's issues relative to casual sex and committed relationships. Unprotected anal intercourse with casual partners during the previous twelve months was associated with growing up without one's father in the home, having been teased for effeminacy during childhood, being defensive about one's masculinity, not trusting men, having been cheated on by boyfriends, and believing that long-term gay male relationships are problematic. ^ It is concluded that the continuing epidemic of HIV infections among local gay men, as well as the hypermasculine form of the gay sexual subculture itself, are nihilistic symptoms embedded in the masculinist gender structure of the larger society. ^

Aggression toward homosexuals: Prevalence, correlates, and motives for antigay behaviors among adolescents and young adults

This study examined the motivating factors for perpetrators of antigay harassment and violence among 752 college freshmen. Large numbers of lesbians, gay men and bisexuals (LGB) are victimized solely because of their sexual orientation. The physical and psychological harm suffered by many of these individuals is alarming. In particular, victimization at school is correlated with a variety of other health risks for LGB students. In order for prevention efforts to be effectively tailored, it may be helpful for researchers to first identify what motivates the assailants. This study tested variables capturing demographic, psychosocial, and attitudinal factors. This purposive sample was selected because these students represent the age group most likely to become perpetrators. The findings suggest that harassment of gay people is common and, in many cases, not motivated by particularly negative attitudes toward homosexuals. Instead, LGB individuals may be viewed as a socially acceptable target by others to harass out of boredom, anger at someone else, or in an attempt to assert their own threatened heterosexuality. Social norms, along with the variety and weakness of individual predictors for antigay harassment, further suggest that heterosexism is endemic and pervasive in our society. Physical attacks against homosexuals, although less common, represent a more serious problem for the victims. This study discovered that there were some leading predictors for these assaults, namely, being male, having been maltreated, being a heavy social drinker, and having defensive, antigay attitudes. The implications of these findings and imperatives for social workers are discussed.

Soviet and Western bloc competition in the less developed world and the collapse of Détente

The purpose of my dissertation was to examine the competition between the U.S.-led Western bloc and the Soviet bloc in the less developed world during Détente. I assessed whether or not the Soviet bloc pushed for strategic gains in the less developed world in the middle-to-late 1970's and whether this contributed to the U.S. decision to abandon Détente in 1979. I made the attempt to test the international relations theory of balance of threat realism (Walt, 1992). I accomplished the test in two ways. First, I measured the foreign aid allocations (military and economic) made by each respective bloc towards the Third World by using a quantitative approach. Second, I examined U.S. archives using the process-tracing/historical method. The U.S. archives gave me the ability to evaluate how U.S. decision-makers and U.S. intelligence agencies interpreted the actions of the Soviet bloc. They also gave me the chance to examine the U.S. response as we evaluated the policies that were pushed by key U.S. decision-makers and intelligence agencies. On the question of whether or not the Soviet bloc was aggressive, the quantitative evidence suggested that it was not. Instead, the evidence found the Western-bloc to have been more aggressive in the less developed world. The U.S. archives also showed Soviet actions to have been defensive. Key U.S. decision-makers and intelligence agencies attested to this. Finally, the archives show that U.S. officials pushed for aggressive actions against the Third World during the final years of Détente. Thus, balance of threat realism produced an incorrect assessment that U.S. aggression in the late 1970's was a response to Soviet aggression during Détente. The evidence suggests structural Marxism and domestic politics can better explain U.S./Western actions. The aggressive foreign aid allocations of the West, coupled with evidence of U.S. decision-makers/agencies vehemently concerned about the long-term prospects of the West, strengthened structural Marxism. Domestic politics can also claim to explain the actions of U.S. decision-makers. I found extensive archival evidence of bureaucratic inter-agency conflict between the State Department and other intelligence agencies in areas of strategic concern to the U.S.

Comparison of snail density, standing stock, and body size between Caribbean karst wetlands and other freshwater ecosystems

Synthesizing data from multiple studies generates hypotheses about factors that affect the distribution and abundance of species among ecosystems. Snails are dominant herbivores in many freshwater ecosystems, but there is no comprehensive review of snail density, standing stock, or body size among freshwater ecosystems. We compile data on snail density and standing stock, estimate body size with their quotient, and discuss the major pattern that emerges. We report data from 215 freshwater ecosystems taken from 88 studies that we placed into nine categories. Sixty-five studies reported density, seven reported standing stock, and 16 reported both. Despite the breadth of studies, spatial and temporal sampling scales were limited. Researchers used 25 different sampling devices ranging in area from 0.0015 to 2.5 m2. Most ecosystem categories had similar snail densities, standing stocks, and body sizes suggesting snails shared a similar function among ecosystems. Caribbean karst wetlands were a striking exception with much lower density and standing stock, but large body size. Disparity in body size results from the presence of ampullariids in Caribbean karst wetlands suggesting that biogeography affects the distribution of taxa, and in this case size, among aquatic ecosystems. We propose that resource quality explains the disparity in density and standing stock between Caribbean karst wetlands and other categories. Periphyton in Caribbean karst wetlands has high carbon-to-phosphorous ratios and defensive characteristics that inhibit grazers. Unlike many freshwater ecosystems where snails are key grazers, we hypothesize that a microbial loop captures much of the primary production in Caribbean karst wetlands.

A state of war: Florida from 1939 to 1945

World War II profoundly impacted Florida. The military geography of the State is essential to an understanding the war. The geostrategic concerns of place and space determined that Florida would become a statewide military base. Florida's attributes of place such as climate and topography determined its use as a military academy hosting over two million soldiers, nearly 15 percent of the GI Army, the largest force the US ever raised. One-in-eight Floridians went into uniform. Equally, Florida's space on the planet made it central for both defensive and offensive strategies. The Second World War was a war of movement, and Florida was a major jump off point for US force projection world-wide, especially of air power. Florida's demography facilitated its use as a base camp for the assembly and engagement of this military power. In 1940, less than two percent of the US population lived in Florida, a quiet, barely populated backwater of the United States. But owing to its critical place and space, over the next few years it became a 65,000 square mile training ground, supply dump, and embarkation site vital to the US war effort. Because of its place astride some of the most important sea lanes in the Atlantic World, Florida was the scene of one of the few Western Hemisphere battles of the war. The militarization of Florida began long before Pearl Harbor. The pre-war buildup conformed to the US strategy of the war. The strategy of theUS was then (and remains today) one of forward defense: harden the frontier, then take the battle to the enemy, rather than fight them in North America. The policy of "Europe First," focused the main US war effort on the defeat of Hitler's Germany, evaluated to be the most dangerous enemy. In Florida were established the military forces requiring the longest time to develop, and most needed to defeat the Axis. Those were a naval aviation force for sea-borne hostilities, a heavy bombing force for reducing enemy industrial states, and an aerial logistics train for overseas supply of expeditionary campaigns. The unique Florida coastline made possible the seaborne invasion training demanded for US victory. The civilian population was employed assembling mass-produced first-generation container ships, while Floridahosted casualties, Prisoners-of-War, and transient personnel moving between the Atlantic and Pacific. By the end of hostilities and the lifting of Unlimited Emergency, officially on December 31, 1946, Floridahad become a transportation nexus. Florida accommodated a return of demobilized soldiers, a migration of displaced persons, and evolved into a modern veterans' colonia. It was instrumental in fashioning the modern US military, while remaining a center of the active National Defense establishment. Those are the themes of this work.

Data compilation on the biological response to ocean acidification: environmental and experimental context of data sets and related literature

The exponential growth of studies on the biological response to ocean acidification over the last few decades has generated a large amount of data. To facilitate data comparison, a data compilation hosted at the data publisher PANGAEA was initiated in 2008 and is updated on a regular basis (doi:10.1594/PANGAEA.149999). By January 2015, a total of 581 data sets (over 4 000 000 data points) from 539 papers had been archived. Here we present the developments of this data compilation five years since its first description by Nisumaa et al. (2010). Most of study sites from which data archived are still in the Northern Hemisphere and the number of archived data from studies from the Southern Hemisphere and polar oceans are still relatively low. Data from 60 studies that investigated the response of a mix of organisms or natural communities were all added after 2010, indicating a welcomed shift from the study of individual organisms to communities and ecosystems. The initial imbalance of considerably more data archived on calcification and primary production than on other processes has improved. There is also a clear tendency towards more data archived from multifactorial studies after 2010. For easier and more effective access to ocean acidification data, the ocean acidification community is strongly encouraged to contribute to the data archiving effort, and help develop standard vocabularies describing the variables and define best practices for archiving ocean acidification data.

Influência dos odores de gato e de cobra no comportamento defensivo e expressão de fos do sistema hipotalâmico de defesa de camundongo

Studies using neuronal tract-tracer in rat have shown that the anterior hypothalamic nucleus, dorsomedial division of the ventromedial nucleus of the hypothalamus and dorsal premammillary nucleus are highly connected. When the rat is exposed to predator or its odor these nuclei have shown a expression of Fos and their lesion reduces defensive behavior against predator. This set of nuclei was named the Hypothalamic Defense System. However, little is known about the response of this system to the odor of different predators or its role in mice. In this work, we exposed Swiss mice to two different predators odor (cat and snake) to verify the Fos expression in the Hypothalamic Defense System, as well as the defensive behaviors displayed. The analysis showed that the mice exposure to cat odor had an increased expression of Fos protein compared to control, while those exposed to snake odor showed no rise in Fos expression, which was corroborated by the behavioral data. Our results indicate that this distinct circuit in mice seems to act differentially to odorous stimuli of different predators, causing distinct behavioral responses of mice and that the odor of snake seems not to be perceived by Swiss mice as a threatening stimulus.

O Programa Nacional Biblioteca da Escola - PNBE: da gestão ao leitor na educação infantil de Natal-RN

This study aims to investigate the process of implementation of Programa Nacional Biblioteca da Escola, PNBE, and the reader's training on Childhood Education level in Natal. The promotion of literary reading is the opportunity of inclusion in a world that is connected to citizenship, to human rights and social justice, because the reading is the way which gives meaning to the life and, therefore, it is a right for everybody. The study is characterized as a qualitative research with evaluative approach. The methodological procedure that constitutes this corpus took place in three stages: the first one was about the analysis of laws and documents of national public policies for the reading promotion; questionnaires were applied by Managing Committee - Natal/RN to CMEIs and the available websites from MEC that provide distribution of the acquis; in the second stage, we adopted the semi-structured interview as a methodological procedure elaborated with open questions that focus on the program management and to the acquis of PNBE; and in the third step we visited the 21 centers of childhood education in Natal for interviewing and to do the exploratory observation in places of reading. The Informant actors in this research are: the advisors of SME - Natal and FNDE, managers and teachers in Municipal Childhood Education Centers who totalize 30 informants. This theoretical and methodological framework follows the studies of Amarilha (1993; 1994; 2002; 2006; 2010; 2012), Bardin (2001), Bogdan; Biklen (1994), Castro (2007; 2008; 2012), Demo (2000; 2006; 2008), Fischer (2006), Moreira; Caleffe (2008), Paiva (2008; 2012), Secchi (2010; 2012), Soares (2003; 2008) and Zilberman (2001; 2003; 2008). The analysis indicates that decentralization strategy which is adopted in public management model will transfer responsibilities and assumption of the PNBE, exempting the actors to planning actions ensuring the efficiency and efficacy implementation on reading policy to national and municipal levels. The qualified acquis that is distributed by MEC reaches every Childhood Education center and does not depend on teacher's desire or it action, only a few of them know about it and they do not have information about the PNBE, neither receive specific training in order to articulate it to the practice of reading with children from Childhood Education. The reading project implemented by private education system in Natal overlaps the PNBE, making it invisible. The reading places that are available for that schooling stage are summarized to the reading corners. In some CMEI, books remain stored in boxes or they are locked in the closet, out of use to the teachers and students. Thus, care for the acquisition, selecting acquis, and a preoccupation to the supply of the reading and books for this education level are lost into volumes of closed boxes, teachers are jettisoned to this process and children do not have any enchantment to the reading or books. In this context, this paper draws attention to how much we should still investigate in order to understanding the perspectives, stresses and challenges from public policies for the reading promotion in our country. We hope that the research will help to improve the management model of the PNBE, ensuring the reading democratization and therefore the reader's training in early Childhood Education.
