Review of the Green Composite: Importance of Biopolymers, Uses and Challenges

Polymers can be utilized for a wide variety of applications since they are lightweight and inexpensive, and their mechanical qualities are usually more than enough. Polymers often undergo a petrochemical production process and have a relatively lengthy elimination time. Green chemistry and green production are crucial in today's technology, which relies increasingly on non-toxic polymers made from natural ingredients. Biopolymers are a type of organic polymer that can break down naturally and pose no threat to human health or the environment. Here, we will take a quick look at the polymer structures that go into making eco-friendly composites in the future. Important polymer types and engineering studies for material manufacturing have been uncovered as a means of avoiding green production's negative effects on the environment. Possible future use of biopolymers as binders in composite materials and their effects on the environment.

EEG-based univariate and multivariate analyses reveal that multiple processes contribute to the production effect in recognition

The production effect (PE) is the finding that reading words aloud rather than silently during study leads to improved memory. We used electroencephalography (EEG) techniques to detect the contributions of recollection, familiarity, and attentional processes to the PE in recognition memory, using Chinese stimuli. During the study phase, participants encoded each list item aloud, silently, or by performing a non-unique aloud (control) task. During the test phase, they made remember/know/new recognition judgments. We recorded EEG data in both phases. The behavioral results replicated the typical pattern with English stimuli: Recognition was better in the aloud condition than in the silent (and control) condition, and this PE was due to enhanced recollection and familiarity. At study, the amplitude of the P3b ERP component was greater in the aloud than in the silent/control conditions, suggesting that reading aloud increases attention or preparatory processing during the intention phase. At test, the recollection-based LPC old/new effect was largest in the aloud condition; however, the familiarity-based FN400 old/new effect was equivalent between the aloud condition and the silent/control conditions. Only the LPC effect correlated with the behavioral effect. Moreover, multivariate pattern analysis (MVPA) showed that accurate classification of items as ‘aloud’ versus ‘new’ mainly occurred in the later period of the recognition response, consistent with the LPC old/new effect. Our findings suggest that the within-subject PE in recognition memory reflects enhanced attention and distinctiveness, rather than increased memory strength. More broadly, our findings suggest that encoding strategies such as production enhance recollection more than familiarity.

The role of precision agriculture in food security

AbstractPrecision agriculture (PA) is the application of information technology to better manage crop and livestock production, heralded as another tool to advance food security around the world. Precision agriculture has the potential to increase productivity, improve resource allocation for inputs such as pesticides, fertilizers, water, feed, and labor, provide for more stable production, and reduce agricultural production's environmental effect. But PA is an approach that can be very different depending on farm characteristics, such as crops and livestock raised, farm size, management, the farms’ access to technical support, and the characteristics of the operator such as age and education. As a result, the adoption of PA has been slower and less uniform compared with some other agricultural innovations. Modern PA management systems are rarely implemented on small low‐mechanization farms, which comprise much of the world's agricultural production, and these farms are common in areas of the world that are the least food secure. And like other farm technology, its benefits go primarily to its adopters and society as a whole, but those who do not, or cannot adopt are left at a relative disadvantage, which unfortunately at present are most farmers around the world. Food security's four main principles according to the Food and Agriculture Organization of the United Nations are food availability, access, utilization, and stability. Precision agriculture has an aspect unlike its predecessor innovations that were primarily production related–because it is based on information, it has the capacity also to better inform and to allow adjustment all along the food supply/demand chain.

Offshore production's effect on Americans’ attitudes toward trade

AbstractAmerican discontent with offshore production features heavily in trade policy debates. But Americans more typically encounter offshore production in apolitical contexts as consumers. We argue that these ostensibly apolitical encounters with offshore production are, in fact, freighted with political consequences. This paper asks: When and for whom does consumer-based exposure to offshore production reduce support for free trade? This is an important in its own right, but also sheds light on the contexts in which more overtly political references to offshore production are likely to find the most fertile ground. We answer these questions using a survey experiment that embeds an offshoring “prime” into an advertisement for pet furniture, varying the location of production across different treatment groups. We find that our experimental exposure to offshore production depressed enthusiasm for free trade, but only when production occurred in China, and mainly among white men living near trade-related job loss. That heterogeneity resonates with work on the economic and social aspects of the decline in American manufacturing employment.

The Treadmill of Information

The world is facing a crisis of global warming due to the release of CO2 and other greenhouse gasses by human activities. Many scholars and stakeholders argue that information and communication technology (ICT) development will mitigate CO2 emissions. Advocacy of technological solutions to CO2 mitigation is consistent with ecological modernization theory's assertion that reflexive societies will modernize sustainably. In contrast, we define the “treadmill of information” as the unique contribution of ICT development to environmental degradation. We examine the impact of ICT development on total CO2 emissions and source-sector emissions from electricity, buildings, manufacturing, and transportation using a multilevel growth model for panel data from 113 countries split into the world, developed country, and less-developed-country samples. We find that the level of fixed telephone development is a strong predictor of higher CO2 emissions in less-developed countries, while internet use predicts higher CO2 emissions in developed countries. The effect of mobile telephone development is not significant. Thus, it appears that ICTs are not having an ameliorative effect on global warming as expected by ecological modernization theorists, and instead reinforce the treadmill of production's negative effect.

The effect of vocal production on vocabulary learning in a second language

The Production Effect (PE) is a memory phenomenon, referring to memory advantage for produced items (read aloud) over non-produced items (read silently). Since vocalizing shows consistent memory benefits, it has been suggested as a mnemonic that can be used to assist vocabulary learning. The present study investigated the PE in L2 vocabulary learning and examined whether learning is durable over time. Hebrew speaking students learned new words in Esperanto, either by vocal production or by no-production. Retention interval varied between participants – from immediate, 1-week, and 2-weeks following the learning phase. The results showed a significant PE – a memory advantage for vocally produced over non-produced words across all learning intervals. Memory performance was higher in the immediate tests than in the delayed tests. The produced words were more durable and showed less memory decay over time. These findings support using vocalization as a simple yet effective memory tool in the first stages of L2 learning, as a classroom activity and as a homework practice assignment.

Green Bank Telescope Observations of 3He+: H ii Regions

Abstract During the era of primordial nucleosynthesis, the light elements , , , and were produced in significant amounts, and these abundances have since been modified primarily by stars. Observations of in H ii regions located throughout the Milky Way disk reveal very little variation in the abundance ratio—the “ Plateau”—indicating that the net effect of production in stars is negligible. This is in contrast to much higher abundance ratios found in some planetary nebulae. This discrepancy is known as the “ Problem”. Stellar evolution models that include thermohaline mixing can resolve the Problem by drastically reducing the net production in most stars. These models predict a small negative abundance gradient across the Galactic disk. Here we use the Green Bank Telescope to observe in five H ii regions with high accuracy to confirm the predictions of stellar and Galactic chemical evolution models that include thermohaline mixing. We detect in all the sources and derive the abundance ratio using model H ii regions and the numerical radiative transfer code NEBULA. The over 35 radio recombination lines (RRLs) that are simultaneously observed, together with the transition provide stringent constraints for these models. We apply an ionization correction using observations of RRLs. We determine a abundance gradient as a function of Galactocentric radius of −(0.116 ± 0.022) × kpc−1, consistent with stellar evolution models including thermohaline mixing that predict a small net contribution of from solar mass stars.

Production Effect in Adults With ADHD With and Without Methylphenidate (MPH): Vocalization Improves Verbal Learning.

Reading aloud (vocal production) enhances memory relative to reading silently, the Production Effect (PE) in memory. Thus, vocalization has been suggested as a mnemonic device. The current study tested the PE in a sample of adults with ADHD and in a control sample, evaluating verbal learning. Twenty adults with ADHD and 21 controls learned a list of words, half by reading aloud and half by reading silently. Free recall test followed. The participants with ADHD performed the task twice (in two different sessions in a counterbalanced order), before self-administration of a single dose of methylphenidate (MPH) and 60-min after dosage. PEs were found for all groups. Memory was better for the controls than for the ADHD group (with or without MPH). In the ADHD group, recall rates and the PE were higher with than without MPH. These results suggest that vocalization yields a larger memory gain with MPH. Possibly, MPH enables the ADHD participants to better shift their attention to the aloud words, enhancing their retrieval rates. Theoretically, these findings stress the role of attention in the PE. (JINS, 2019, 25, 230-235).

The Effect of Presentation Mode and Production Type on Word Memory for Hearing Impaired Signers.

Production effect (PE) is a memory phenomenon referring to better memory for produced (vocalized) than for non-produced (silently read) items. Reading aloud was found to improve verbal memory for normal-hearing individuals, as well as for cochlear implant users, studying visually and aurally presented material. The present study tested the effect of presentation mode (written or signed) and production type (vocalization or signing) on word memory in a group of hearing impaired young adults, sign-language users. A PE paradigm was used, in which participants learned lexical items by two presentation modes, written or signed. We evaluated the efficacy of two types of productions: vocalization and signing, using a free recall test. Twenty hearing-impaired young adults, Israeli sign language (ISL) users, participated in the study, ten individuals who mainly use manual communication (MC) (ISL as a first language), and ten who mainly use total communication (TC). For each condition, we calculated the proportion of study words recalled. A mixed-design analysis of variance was conducted, with learning condition (written-vocalize, written-signed, and manual-signed) and production type (production and no-production) as within-subject variables, and group (MC and TC) as a between-subject variable. Production benefit was documented across all learning conditions, with better memory for produced over non-produced words. Recall rates were higher when learning written words relative to signed words. Production by signing yielded better memory relative to vocalizing. The results are explained in light of the encoding distinctiveness account, namely, the larger the number of unique encoding processes involved at study, the better the memory benefit.

The impact of different background noises on the Production Effect

The presence of background noise has been previously shown to disrupt cognitive performance, especially memory. The amount of interference is derived from the acoustic characteristics of the noise; energetic vs. informational, steady-state vs. fluctuating. However, the literature is inconsistent concerning the effects of different types of noise on long-term memory free recall. In the present study, we tested the impact of different noises on recall of items that were learned under two conditions – silent or aloud reading, a Production Effect (PE) paradigm. As the PE represents enhanced memory for words read aloud relative to words read silently during study, we focused on the effect of noise on this robust memory phenomenon. The results showed that (a) steady-state energetic noise did not affect memory, with a recall advantage for aloud words (PE), comparable to a no-noise condition, (b) fluctuating-energetic noise and fluctuating-informational (eight-talkers babble) noise eliminated the PE, with similar recall for aloud and silent items. These results are discussed in light of their theoretical implications, stressing the role of attention in the PE. Ecological implications regarding studying in noisy environments are suggested.

Production on hold: delaying vocal production enhances the production effect in free recall

ABSTRACTThe Production Effect (PE) represents superior memory for produced (read aloud) relative to non-produced (silently read) items. Another method of improving memory is taking a test on the study material – the Testing Effect. We evaluated the combined influence of both effects on free recall memory, using delayed vocal production, in which study words were vocally produced only after their disappearance. Such procedure involves an initial instant test since participants had to vocally retrieve the words (rather than read them aloud). In five experiments, participants were presented with study words that they were instructed to learn by no-production (reading silently), immediate production (reading aloud), delayed reading aloud, or delayed vocal production (instant retrieval). The results showed superior recall for delayed production over all other conditions. We suggest that the source of this superiority is the desirable difficulty induced by the addition of the initial test (retrieval effort) to the vocal production. The novel delayed production condition forms a superior mnemonic.

Sustained lean transformation of working conditions: A Swedish longitudinal case study

AbstractStudies of lean production's effect on working conditions are mixed but point toward worsened conditions. The aim of this longitudinal study was to assess how lean contributes to transforming work characteristics in a medium‐sized specialized industrial family business. A mixed methods approach was used to combine an external assessment of work characteristics with self‐reported employee questionnaires. Favorable psychosocial working conditions were indicated, with role conflicts decreasing over time. The assessment of work provided descriptions of how lean practices contributed to decreased task control due to standardized work and simplified work processes. At the same time, employees still had opportunities to influence their long‐term work assignment. There was also a trend toward job enlargement through new, higher‐skilled tasks, multiskilling, and extended opportunities to influence work through different continuous improvement activities. The participative lean approach and type of skilled jobs may have contributed to this transformation.

The production effect in adults with dysarthria: improving long-term verbal memory by vocal production

ABSTRACTPeople show better memory for words read aloud relative to words read silently, the Production Effect (PE). Vocalisation at study makes the produced (aloud) words more distinct than the non-produced (silent) words, hence more memorable. Such encoding distinctiveness is related to the additional processing of aloud words that is later used during retrieval. This study investigated the PE in dysarthric adults, characterised by speech production difficulties. Their memory performance (recognition) was compared to a group of healthy adults. Results showed a PE for both groups. The production benefit was significantly larger for the dysarthric adults, despite their overall memory performance being reduced relative to controls. The results demonstrate long-term verbal memory deficits in dysarthria, and suggest that vocalisation (although impaired) may assist in remembering. Hence, vocalisation may be used in intervention contexts with this population, to compensate for memory decrease.

Evaluating the basis of the between-group production effect in recognition.

Reading a list of words aloud can improve recognition over silently reading them. This between-groups production effect (PE) cannot be due to relative distinctiveness because each group studies only 1 type of item. We tested 2 other possibilities. By a strategy account, a pure-aloud group might benefit from use of a production-based distinctiveness strategy at test (e.g., "Did I say this word aloud?"). By a strength account, aloud items may simply be more strongly encoded than silent items. To evaluate these accounts, we tested whether a between-group PE occurs when participants experience a salient within-group manipulation of font size, generation, or imagery at study. The answer was yes, except when imagery was the within-group task. This pattern, and aspects of participants' strategy reports, fit well with a strategy account if it is assumed that the imagery task led participants to abandon a production-based strategy. However, many of our findings were also compatible with an evaluated strength account if it is assumed that the imagery task led participants to abandon evaluating memory strength. In conjunction with recent findings, we suggest that multiple processes may contribute to the PE, and the relevant subset in play will differ as a function of study design, study task, and memory test.

Influence of retrieval mode on effects of production: Evidence for costs in free recall.

Study modality (visual, auditory) of words as well as production mode (reading aloud, writing down) have been shown to influence the production effect (PE). When study words are presented visually, reading them aloud yields superior memory. However, when the same study words are presented aurally, writing them down leads to superior memory. Missing in PE studies is the variable of retrieval mode (written, aloud), which was addressed in the present study. In a pair of experiments, we manipulated the 3 variables-study modality, production mode, and retrieval mode-in a factorial fashion. With visual study, aloud production mode (vocalizing) was found to be superior to written production, in both retrieval modes (written and aloud). However, the difference between the productions was significantly smaller in the aloud retrieval mode relative to the written retrieval mode. With auditory study, written production mode was superior to aloud production mode, in the written as well as in the aloud retrieval modes. Here, the difference between the productions was significantly smaller in the written relative to the aloud retrieval mode. In other words, the difference between productions was smaller for the retrieval mode that matched the superior production. We interpret these findings using a retrieval-cost account.

Auditioning the distinctiveness account: Expanding the production effect to the auditory modality reveals the superiority of writing over vocalising

The production effect (PE) documents the advantage in memory performance for words that are read aloud during study, rather than words that are read silently. Until now, the PE was examined in the visual modality, as the participants read the study words. In the present study, we extended the PE phenomenon and used the auditory modality at study. This novel methodology provides a critical test of the distinctiveness account. Accordingly, the participants heard the study words and learned them by vocal production (saying aloud) or by writing, followed by a free recall test. The use of the auditory modality yielded a memory advantage for words that were written during study over words that were vocally produced. We explain this result in light of the encoding distinctiveness account, suggesting that the PE is determined by the number of different encoding processes involved in learning, emphasising the essential role of active production.

Electric elephants and the lively/lethal energies of wildlife documentary film

Amid growing enthusiasm for documentary filmmaking as a more‐than‐human research methodology, particularly in geography, I interject a cautionary reflection on the possibilities and limitations of this medium, emphasising documentary film production's effects on nonhuman life. From one of the first films ever made, in which Thomas Edison electrocutes Topsy the elephant, to contemporary wildlife documentaries that observe the lives and deaths of animals, film's affective potential to electrify, animate or enliven has existed in tension with its reliance on an encounterable, killable and invade‐able animal life. Accordingly, this paper first briefly reviews the emerging context of filmmaking as a research tool for more‐than‐human or animal geographies, focused on the relationship between animal documentary film and affect. I then complicate this lively energy through an examination of the conditions of production for animal film, particularly wildlife documentary, underscoring the speciesism that positions animals as disposable objects. Drawing on historical and contemporary examples as well as my own ambivalent experience making a short research film on wild animals circulating within global live wildlife trade, I show that a reliance on an encounterable animal, and a persistent taking of or impinging on animal life, underpins wildlife documentary film's ability to bring animals to life on film screens. At a time when documentary filmmaking is poised to become a dominant method in more‐than‐human geography and animal studies more broadly, this long history of violence, or film's lethal energies, must be considered more centrally.

The Effects of Large-Scale Hog Production on Local Labor Markets

Although the negative externalities of large-scale hog production have been well studied, econometric estimates of its potentially positive labor markets effects are lacking. We use the geographic shifts in large-scale hog production between 1992 and 2007 to estimate such production's effects on local farm and nonfarm labor markets. We find that every additional 1000 head at large-scale facilities in a county generates 0.57 additional large-scale hog operation jobs, 0.04 fewer small-scale hog operation jobs, 0.16 fewer nonhog-related agricultural jobs, and 0.59 additional nonfarm jobs, for a total of 0.96 jobs. Our total estimate is lower than previous ones based on input-output modeling.

Don't Plan! The Use of the Notion of ‘Culture’ in Transforming Obsolete Industrial Space

AbstractHow is the notion of ‘culture’ understood and used in planning the transformation of obsolete industrial space? This article analyses the evidence from a current planning project in Suvilahti, Helsinki. It shows that ‘culture’ is imagined and employed as an instrument capable of producing difference in urban space. The transformation of the Cable Factory in Helsinki and the subsequent consensus on the importance of ‘culture’ are shown to have influenced the planning of Suvilahti. On the one hand, planning is being carried out with a deliberate minimization of planning interventions and the promotion of the spontaneous, non‐planned practices of cultural producers: the future Suvilahti is imagined as a ‘cultural enclave’ and its community is characterized as a ‘living organism’. On the other, ‘culture’ is planned in terms of its supposedly positive effects on urban space. Planners do not want to interfere with the non‐planned character of ‘cultural production’, yet at the same time they express certainty about cultural production's positive spatial and socioeconomic effects. The transformation of Suvilahti is playing an important part in the large‐scale planning project to redevelop the old industrial harbour in Kalasatama, Helsinki. The changes in the nature of planning are analysed under the concept of cultural governmentality.

Real options and a large producer: the case of electricity markets

In this paper we extend the real option theory to consider the situation of a large producer and we employ the model to electricity markets. This is important because many producers in these markets affect the market supply and, therefore, also the electricity price. This production price effect influences not only on the assets that the energy company owns but also on its investment opportunities. We show that this production's price effect has to be considered in the investment analysis if the company is not able to hedge the price effect in the financial markets and if there is no competition on the investment opportunity.
