Increased Production of Recombinant O-Phospho-L-Serine Sulfhydrylase from the Hyperthermophilic Archaeon Aeropyrum pernix K1 Using Escherichia coli
Authors: Nakamura Takashi , Takeda Emi , Kiryu Tomoko , Mori Kentaro , Ohori Miyu , Kikugawa Eiki , Ishikawa Kazuhiko
Published: August 2019

Background:

O-phospho-L-serine sulfhydrylase from the hyperthermophilic archaeon Aeropyrum
pernix K1 (ApOPSS) is thermostable and tolerant to organic solvents. It can produce nonnatural
amino acids in addition to L-cysteine.

Objective:

We aimed to obtain higher amounts of ApOPSS compared to those reported with previous
methods for the convenience of research and for industrial production of L-cysteine and non-natural
amino acids.

Method:

We performed codon optimization of cysO that encodes ApOPSS, for optimal expression in
Escherichia coli. We then examined combinations of conditions such as the host strain, plasmid, culture
medium, and isopropyl β-D-1-thiogalactopyranoside (IPTG) concentration to improve ApOPSS yield.

Results and Discussion:

E. coli strain Rosetta (DE3) harboring the expression plasmid pQE-80L with
the codon-optimized cysO was cultured in Terrific broth with 0.01 mM IPTG at 37°C for 48 h to yield
a 10-times higher amount of purified ApOPSS (650 mg·L-1) compared to that obtained by the conventional
method (64 mg·L-1). We found that the optimal culture conditions along with codon optimization
were essential for the increased ApOPSS production. The expressed ApOPSS had a 6-histidine tag at
the N-terminal, which did not affect its activity. This method may facilitate the industrial production of
cysteine and non-natural amino acids using ApOPSS.

Conclusion:

We conclude that these results could be used in applied research on enzymatic production
of L-cysteine in E. coli, large scale production of non-natural amino acids, an enzymatic reaction in organic
solvent, and environmental remediation by sulfur removal.

BACKGROUND

Health games provide opportunities for the treatment and prevention of childhood obesity. We developed a motion-controlled serious game for children that addresses 3 core topics of nutrition, physical activity, and stress coping. It is the first serious game that extensively targets the dietary energy density principle (DED-P) in relation to nutrition. The game is intended to provide an additional educational component for the prevention and treatment of obesity in children.

OBJECTIVE

The Kids Obesity Prevention study aimed to evaluate the newly developed game and to evaluate how well children are able to understand and apply the DED-P.

METHODS

This cluster randomized controlled trial collected data from 82 primary school children aged 9 to 12 years and their parents at baseline (T0), at 2 weeks after study commencement (T1), and at the 4-week follow-up (T2). The dropout rate was 3.6%. The intervention group (IG) played the game within 2 weeks (2 sessions with different game modules). One part of the game involves selection of food with the lower energy density when presented with a pair of foods. This allows assessment of whether the children have understood the DED-P and whether they can apply it to unknown foods under time pressure. The control group (CG) received a brochure about the food pyramid concept and physical activity. The primary outcome was the gain in knowledge (nutrition and stress coping) and measured with a pretested questionnaire. The secondary outcomes were the maintenance of knowledge, application of the DED-P, feelings during game play, game acceptance, and behavioral measures (physical activity, media consumption, and dietary intake).

RESULTS

The knowledge score ranging from 0 to 100 increased from T0 (IG: 53 [SD 10], CG: 50 [SD 11]) to T1 (IG: 69 [SD 11], CG: 52 [SD 12]) in IG versus CG (P<.001). At T2, the knowledge score of IG remained at the same level as that of T1. Game data showed that after DED-P education, the classification under time pressure of unknown versus known food pairs according to their DED category was similar (hit rate around 70%). Overall, 95% of the children liked the game very much or much. No group changes were observed at the behavioral level.

CONCLUSIONS

The Kids Obesity Prevention program sustainably increased knowledge in the areas of nutrition and stress coping, and children were able to apply the DED-P.

educación como bien público y común. Reformular la gobernanza de la educación en un contexto cambiante
Authors: Locatelli Rita
Published: August 2019

El concepto de educación como bien público ha constituido durante mucho tiempo un principio fundamental del discurso internacional sobre el desarrollo de la educación. Tradicionalmente, ha supuesto la responsabilidad primordial de las instituciones públicas de impartir y financiar las oportunidades educativas. Sin embargo, esta función se pone cada vez más en cuestión por la mayor diversificación de los agentes implicados y de las fuentes de financiación a todas las escalas de la educación. En este documento se revisa el principio de la educación como bien público a la luz de las tendencias actuales de privatización y mercantilización de la educación. Teniendo en cuenta las implicaciones tanto económicas como políticas de la privatización, se reformula el debate teórico sobre la educación en el ámbito público. Partiendo de la necesidad de restablecer un espacio democrático de participación, se sostiene que el concepto de educación como bien común puede representar un marco complementario útil para su gobernanza en un contexto cambiante.

UsingTCP(TransmissionControlProtocol)inwirelessnetworkscanaffectitsperformanceduetoits lack of ability to identify packets losses properly, causing the triggering of its congestion control mechanism. Some TCP variants were proposed to improve this control, being TCP-UEM one of them. This variant allows the evaluation of the link reliability in wireless networks in time intervals, keeping the end-to-end semantics. TCP-UEM was implemented in FreeBSD OS and its performance with relation to segment transfer rate (in Mbps) was compared to two other variants, TCP-NEWRENO and TCP-CUBIC. This paper describes TCP-UEM, discusses results of the tests and the statistical analysis that were carried out using two scenarios. For each scenario, 30 samples of 30 seconds of execution time with different loss rates were collected. The results showed that TCP-UEM presented a good performance, achieving a performance higher than the other two variants in the majority of the tests, with different loss rates.

Este artigo engendra uma discussão acerca dos empreendimentos imobiliários, neste caso, os espaços residenciais fechados e a natureza mitificada produzida sobre uma estrutura ideológica. Os espaços residenciais fechados promovem a criação de ambientes urbanos, fictícios de retorno a natureza, sintetizam e simplificam a realidade da cidade e promovem a fragmentação socioespacial. Buscou-se entender teorias e conceitos construídos ao longo da historia sobre a natureza e a cidade. E no caso concreto analisar o condomínio Boulevard das Colinas na Cidade de Caetité – BA, onde os incorporadores imobiliários apropriam do discurso ideológico do “natural”, através de propagandas, que têm como objetivo a valorização do empreendimento. Observa-se, que através das propagandas muitas ideias de afastamento, diferenciação começam a se materializar no espaço urbano.

Third party ownership arrangements: Is a ban in football really appropriate?
Authors: Herberger Tim A. , Oehler Andreas , Wedlich Florian
Published: August 2019

Football companies (equivalent to professional sport teams) are increasingly challenged with raising capital. However, future athletic success is highly uncertain and associated cash flows are difficult to predict which makes it difficult to attract investors. An alternative financing instrument that has become more popular in recent years is Third Party Ownership arrangements (TPOs). TPO is a way for financiers to invest in the player squad of a football company and therefore reducing investment risks. Due to the wide usage in football and legal concerns about TPOs, FIFA has forbidden the implementation of TPOs since 2015. But, the question arises, whether a ban of TPOs is really appropriate avoiding a potential conflict of interests as well as problems in ethics and compliance. To address these aspects and finally to judge the appropriateness of TPOs for football companies and the ban itself, a financing-theory-oriented view on the design and functional possibilities of TPOs is needed, but still missing in the literature. Our paper tries to fill this gap and sets the economic basics for a profound legal and economic discussion on the use of TPOs in football as well as sports in general.
Information Dissemination through Embedded Financial Analysts: Evidence from China
Authors: Li Zengquan , Wong T. J. , Yu Gwen
Published: August 2019

When emerging market firms disclose relationship-based transactions, they face a trade-off in which greater transparency may help lower their cost of capital at the cost of revealing proprietary information. We find that firms overcome this challenge by relying on analysts within their private networks (i.e., connected analysts) who, through repeated interaction with the firm, can better verify relationship-based transactions. Using Chinese firms, we show that firms with more connected analysts have more accurate consensus forecasts and lower forecast dispersion. When a connected analyst departs and stops covering a firm, the accuracy and informativeness of the unconnected analysts' forecasts decrease, suggesting that information spills over from the connected analyst to analysts outside the network. We find a potential mechanism for this information spillover: communication through common institutional clients, which suggests that embedded financial analysts—those sharing close connections with firms and analysts—serve as a channel for disseminating proprietary, hard-to-verify information.

The Effects of Economic and Social Bonds with Clients on Tax Professionals' Recommendations
Authors: Vermeer Beth Y. , Spilker Brian C. , Curatola Anthony P.
Published: August 2019

This study provides new insights about how tax professionals' economic and social relationships with clients separately and jointly affect tax professionals' propensity to recommend aggressive tax positions to clients when resolving ambiguous issues. In an experiment with 133 practicing tax professionals, we manipulate the economic importance of the client and client identification (a social construct). We find that as the economic importance of the client increases, professional recommendations follow an inverted U-shaped pattern. Tax professionals more strongly recommend aggressive positions for clients of moderate economic importance than for clients of low or high economic importance. We also find that tax professionals with high versus low client identification provide more aggressive recommendations for clients of low or moderate economic importance, but not for clients of high economic importance. This paper contributes to the literature by identifying a boundary condition on client identification that has not been considered in prior accounting research.
The Impact of Vivid Graphical Presentation of Financial Information in Digital Annual Reports on Investors' Impressions of Management and Firm Performance
Authors: Zhang James (Yibo)
Published: August 2019

This study examines the effect of graphical vividness on nonprofessional investors' impressions of management and firm performance when the financial performance news is either positive or negative. Conducting a 2 × 2 between-participants experiment with 470 participants from Amazon Mechanical Turk (M-Turk), I find that when the news is positive, nonprofessional investors have more positive impressions of management, which, in turn, leads to more positive impressions of firm performance when the graphical presentation is vivid versus pallid. In contrast, when the news is negative, presenting graphs vividly has little effect on nonprofessional investors' impressions. The study contributes to regulators and practice by demonstrating that allowing a high degree of presentation flexibility in digital annual reports has behavioral outcomes to nonprofessional investors' judgments and decisions. The study also contributes to the strategic disclosure literature by demonstrating the impact of graphical vividness in presenting financial performance information.

The results can be summarized as follows: (1) In implementing the family domestic work, there have been kecederungannya collaboration between husband and wife, in this case the husband has been carrying out domestic work, although limited to certain jobs fatherly. However, the participation of the husband, not because of their responsibilities within the family, but because his wife wanted to help ease the job. This means there is still gender bias in the family, especially mengkotakkan work between men and women. (2) The role of mothers in the family economy in the family economy provides a substantial contribution, even among those who earn more than their husbands, but the presence of tersebutmasih permanent income defined as the additional revenue. This recognition not only by their husbands, but also the opinions of these mothers. (3) In making decisions, it seems there has been cooperation between the husband and wife, but the things which ranges around the daily needs of the domestic like procurement, the issue of household appliances, clothing problems of children and so forth, it was entirely in the hands of the istri.Jadi thus still there is gender bias in the research area of decision making.

The essence of national development is to build on a solid foundation and strong foundation in the form of certain conditions in various national life. Community development there are two challenges that need to be considered to build the organization (organization development) and economic development (economic development). In the development of organizations, the organization is the frame work of every form of cooperation to achieve a common goal, therefore it needs to be built on the basis of a democratic, dynamic and harmonious relationship. Likewise with the elderly community groups, based on Boyle's taxonomic thinking about the type of non-formal education is divided into three types: developmental, institutional, and informational. Developmental programs are also called community development programs, where the main program objectives are solving social, economic, cultural, political, and defense and security problems facing the target group through action programs. An instituional program is also called a training program aimed at mastering a set of capabilities (knowledge, attitudes and / or skills) by the target group. While the informational program can be called also with counseling or publicity, aims to achieve a set of information by the target group. Thus the community development program is one of the types of non-formal education programs.

PAUD institutions are often interpreted as a place of learning for children who are only oriented to the skills and knowledge of reading, writing, counting, and drawing. PAUD institutions should focus on children's development related to religious and moral, physical, cognitive, language, social, emotional and artistic aspects. Thus the educational services provided by PAUD institutions must be able to facilitate all aspects of child development through enjoyable learning activities and help increase understanding of parents or the surrounding community about playing as a fun learning activity. Fun learning activities for early childhood need to be designed to help children get real life simulations in their daily activities. PAUD institution learning activities need to be adjusted to the stages of child development based on experiential learning model learning principles. On that basis, an activity is needed that facilitates the creation of learning experiences for managers and parents or community members in PAUD institutions about experiential learning.Keywords: Childhood Education (PAUD), Experiential Learning

Analysing a Resilience Development Program: who benefits?
Authors: Heather Jonathon , Shannon Elizabeth , Pearson Sue
Published: August 2019

Objective: This article presents findings from an analysis of resilience and resilience development. Design: Convergent, mixed-methods research used an online survey to gather data from participants in a resilience development program, in combination with a small number of semi-structured interviews with managers. Setting: The research was carried out on public sector health and human services managers and staff, during a time of ‘downsizing’ and organisational restructuring. Main outcome measures: The Wagnild Resilience Scale was used to measure resilience levels and their association to respondent demographic, educational and professional groupings. Results: Interviews with senior managers found a consensus of opinion that resilience was important; and the resilience development program either had, or potentially had, benefits for their workforce. Perceptions about exactly who would benefit differed between senior managers and participants in the program. Participant survey results indicated that respondent characteristics (age, occupational group, highest level of education and departmental role) were associated with differing levels of resilience. Conclusions: This study found that resilience development may benefit two groups of employees in particular: non-nursing staff under 50 years of age, and managers. These findings add to the body of knowledge associated with staff resilience development, organisational change management and organisational learning. These results inform health service manager practice by suggesting potential target groups for resilience development.
