GLOBALIZACIJA SEKTORA PRIVATNE BEZBEDNOSTI I DRUŠTVENA ODGOVORNOST
Authors: Simović Slobodan
Published: November 2021

Odgovornost, pod kojom se podrazumeva verovatnoća da će neko odgovarati za neku svoju radnju, veoma je složen pojam, jer ta složenost obuhvata odnos čoveka prema društvu, ali i čovekov odnos prema samom sebi. Društvena odgovornost podrazumeva obavezu menadžmenta da preduzme one akcije koje će doprineti blagostanju i interesima društva, ali i organizacija. Korporativna društvena odgovornost obuhvata odgovoran odnos kompanija prema društvu, pri čemu se taj odnos zasniva na ukupnosti društvenih, etičkih, ekoloških i ekonomskih vrednosti značajnih za proces odlučivanja. Prema tome, korporativna društvena odgovornost se odnosi na ponašanje organizacija prema društvu, a ponašanje organizacija prema društvu se zasniva na vrednostima koje društvo ističe kao dominantne i značajne za njegov dalji razvoj. Posebno danas kada se globalna industrija privatne bezbednosti drastično uvećala. Ne treba i pominjati da se današnje kompanije u svom poslovanju sve više susreću sa pritiscima i zahtevima socijalne sredine da se odgovorno ponašaju, posebno u oblasti zaštite životne sredine, u delu koji se odnosi na ostvarivanje ljudskih prava i sloboda, zahteva se i odgovornost o pitanju zaštite prava potrošača, u oblasti javnosti rada i kontrole rada kompanija od strane javnog mnjenja i sl.
BSC SOFTWARE TO EFFICIENCY AND PERFORMANCE
Authors: Pravdić Predrag , Kučinar Gačić Rada
Published: November 2021

Management processes directed primarily to the user and thus improve the efficiency and effectiveness of operations in exceeding user demands and expectations. So that organizations realize the benefits on all levels, as compared with external partners and business environment, as well as internally within the organization. But in practice, systems for managing corporate change often point to the shortcomings and lack of commitment at the level of corporate governance in order to improve the efficiency of the process. Taking into account the problems they face at the same company, Balanced Scorecard - BSC stands out as especially suitable tool for the management of corporate change. BSC translates mission and strategy of the organization in the comprehensive set of measures that provide a framework for the implementation of the strategy. But many senior managers recognize that no single measurement can provide enough information about the critical areas of the business. Therefore, a balanced set of measurements is needed. Organizations today use decentralized business units that focus on intangible knowledge, capabilities, and relationships created by employees. Some organizations understand that strategy must become a continual and participative process. The change from centralized command, and financial measures that come from past actions can no longer measure the objectives that need to be addressed. We must measure the strategy and the best tool to do this is balanced scorecard. BSC makes it possible to establish a model in the profit organization, so that the strategic aspects of the observed set relevant objectives and include features that will be measured. BSC aims to improve business processes for a streamlined process can improve product quality to customer satisfaction. So satisfied and loyal customer is a guarantee of higher profits. The balanced scorecard combines an effective measurement system that helps solidify a company’s strategic objectives with a management system that can help drive change in key areas such as product, process, customer, and market development. The measures of the balanced scorecard helps focus a company’s strategic vision, encourages thinking about current and future success and helps provide a balance between external and internal measures. This paper presents BSC modeling of key success factors represented in strategy map of profit organization and how it affects the organization’s measurement system.

Published: November 2021

The research gives an overview of the Heavenly (in/inma/immu/inmu, lit: ‘heaven/heavenly earth’) area, its construction, and its gods. Udmurt narratives about the creation of the world are related to biblical subjects and images. In their folklore we find the image of a heavenly stove and heavenly table, i.e. the constellation of Ursa Major. The supreme deities include the creator God (Inmar, Kuaz’, Kyldys’in/Kylchin) and the female deities (Kaldyk-mumy/Kaltak, Shundy-mumy, “Mother-Sun / Mother of the Sun”, Invu-mumy “Mother of Heavenly Water / Heavenly Grace”, Invozho-mumy “Mother-Invozho, Goddess of Summer Feast Time, i.e. Transitional Time”, Gudyri-mumy, Thunder-Mother, Muz’’yem-mumy, Mother-Earth).
Inmar, the Udmurt God, in Modern Udmurt Literature
Authors:   Russian Academy of Sciences Scientific Centre in Kazan, Arzamazov Aleksey
Published: November 2021

One of the productive directions of research into Udmurt literature (and more broadly other Finno-Ugric ‘small’ literary traditions) is the identification and interpretation of multidimensional mythological clusters, textual representativeness and semantic ambivalence. In this work I have focused on only one aspect, the functional and semantic field of a particular character in Udmurt mythology and national poetry at the turn of the 21st century. The chosen mythological character is Inmar/God. The study has predominantly focused on ethnic and futuristic poems by Petr Zakharov, Viktor Shibanov, and Larisa Orekhova, characterised by a high concentration of mythological symbols. The presented research demonstrates how complex the image of Inmar is for direct artistic understanding.

Forest spirits are widely represented in the Udmurt traditional belief system. The present study is aimed at systematising traditional folk beliefs about the best-known mythological beings living in the woods, namely the n’ulesmurt (‘forest man’), palesmurt (lit: ‘half-man’), and obyda (‘forest woman’). The article provides a detailed description of the appearance of forest spirits, analyses their distinctive features and functions, and presents how beliefs about those mythological beings have evolved over the last centuries.
Tradition and Diversity among Udmurt Sacrificial Priests
Authors:   Institute of Eastern Languages and Cultures (INALCO), Paris, Toulouze Eva , Niglas Liivo ,   University of Tartu, Estonia
Published: November 2021

In the Udmurt diaspora of Northern Bashkortostan the traditional Udmurt religion is very much alive and is part of the villagers’ everyday lives. Rituals are regularly held both at the village level and in the wider community, composed of several villages, involving the whole population. Since 1990, a revitalisation process has taken place in almost all villages of the region, so that by the beginning of the 2020s, the huge majority of villages have their own ceremonies and their own sacrificial priests, even where the tradition had been interrupted for decades. This article focuses on the key figure in Udmurt ritual, the sacrificial priest, called the vös’as’, and attempts to sketch a pattern of function-performance and transmission, taking into account practice in groups of villages. It also reflects on its historical perspective in a Finno-Ugric context in which the practice of ethnic religions is often seen and/or used as a marker of ethnicity.
The Ritual Importance of the Chuk, a Symbolic Bundle of Thread

The article aims to analyse one of the specific objects of Udmurt traditional culture, chuk (in southern dialects) / tug (in northern dialects), i.e. red thread/yarn; a bunch or bundle of different coloured threads, fringes, ribbons, shreds; towels, bedspreads, and kerchiefs. The multifunctional nature of the object is revealed in everyday and ritual contexts; it can be of different forms and convey various meanings. Depending on the situation, chuk is regarded as a label, a protective charm, a sacrifice gift, or a tangible symbol of a substitute for the human soul. In everyday situations chuk is used in apotropaic magic and folk medicine. For example, red thread/yarn is worn around the ring finger to cure a sty, or it can be worn on an infant’s right wrist to protect him or her against the evil eye. A bunch of wool or linen threads is attached to knitted and woven things when their pattern is copied. The custom of marking young animals with brightly coloured strips of material, usually red, has survived to this day. Chuk is an essential attribute in the Udmurt calendar rites of the spring and summer cycles, wedding ceremonies and recruit rites. In calendar rituals chuk is recognised as a kind of sacrificial offering or gift. Praising flourishing nature alongside youth and early adulthood, the rites of welcoming spring and summer (Vöy, Shrovetide; Akashka/Byddzh’ynnal, Easter; Gershyd, Whitsunday) are regularly marked by the offering of different types of cloth (towels, kerchiefs, head towels for young married women) to mark passage through different stage of life. At different stages of the wedding ceremony (including pre- and post-wedding) the semantics of chuk depends on how it correlates with the participants of the ceremony: in regard to the bride chuk is definitely recognised as a gift, in regard to the groom’s relatives and friends as a way to personify a humorous image of strangers. In recruits’ rites chuk is hammered into the main ceiling beam of the recruit’s house and serves as a material symbol of, or substitute for, the human soul of the recruit, combining the functions of a label, a protective charm and a sacrifice.

Authors:   Universidade Federal Fluminense, Niterói, Brazil., Sarmento Marcus , Ribeiro Ferreira Miguel Luiz
Published: November 2021

Executing projects according to its estimated cost and schedule is fundamental to guarantee the economic and financial viability of the businesses associated with them. In this context, the estimated duration of an activity is very important for the development of the project schedule and budget. Therefore, determining the main factors that contribute to labor productivity becomes imperative. This research identified the main factors affecting labor productivity in construction projects around the world. Then, it was verified the pertinence of these factors to the Brazilean industry . The 56 factors identified were prioritized, according to the importance index, and categorized into four main groups: management, labor, external and technological. Factors such as: poor material management, lack of construction manager’s leadership, site supervision inefficiency, strikes and lack of tools are at the top of the list. It was also observed the balance between the management, technological and external groups. Finally, when compared to researches carried out in other countries, there is a reasonable correlation between the results identified by this research and those found by previous researches.
mega events paradox

Published: November 2021

Considering the urban transformations and the development of the hotel sector in the City of Rio de Janeiro driven by the 2016 Olympic Games, this study aims to understand how the hotel industry behaves in terms of organic growth and investments during periods of mega international events. To this end, a qualitative case study research was carried out that included 7 different hotel brands whose results were coded and categorized resulting in a theoretical-conceptual framework responsible for identifying some competitive pressures on traditional hospitality, including 6 different challenges: (1) political institutional insecurity, (2) perceptions of the media, (3) public security, (4) other national and foreign locations, (5) new videoconference technologies, and (6) Online Travel Agencies. It was found that the exponential growth in the number of beds in the city in the years leading up to the 2016 Olympics generated several complications for the industry at that time. The logic of this expansion is discussed throughout the paper during different phases and the aim is to help fill a gap left by empirical research in the area, which has little explored the logic behind the option of investing during Olympic Cycles.
Socio-Economic Factors Influencing Youth Participation in Local Government Planning and Budgeting in Iringa Municipality
Authors: Mpwehwe Paul Balivumu
Published: November 2021

This study focused at exploring the socio-economic factors influencing youth participation in planning and budgeting in Local Government Authorities (LGA) in Iringa Municipal Council. The study employed a mixed approach where data were collected through questionnaires and interviews. Findings from the study indicated that the youth did not participate in any activity in their LGA in the past three years whereby it was only 31(19.1%) of the youth respondents who participated in at least one of the local government activities in the past three years. Findings further indicated more male participation in planning and budgeting than female. On the other hand findings revealed that education has influence on youth participation in planning and budgeting whereby the more educated youth participated more than none educated youth. Based on the findings, it was concluded that there was an information gap between leaders and youth especially on local government planning and budgeting; hence the study recommended for creation of awareness on the right of the youth to participate in planning and budgeting. The study also recommended regular meetings with the youth in the wards/ streets to hear out their challenges and needs. Furthermore, the study urged the government to use youth friendly tools to create awareness to the youth on planning and budgeting processes and opportunities available in their locality and how they can tap into that pool of opportunity.

Published: November 2021

Since the early 2000s, pineapple from Côte d’Ivoire has suffered a discount in its marketing due to the heterogeneity of the quality of its fruit and the arrival of MD2 on the international market. In order to help pineapple from Côte d'Ivoire once again win back the international market, Ananas comosus hybrids with an early natural coloring have been developed at the CNRA. The agronomic performances of these hybrids were tested at the research station of Anguédédou. Vegetative characteristics such as plant fresh mass, stem fresh and dry mass, number of leaves generated and leaf D fresh mass of these hybrids H1, H2, H3 and H4 were compared to those of cultivars Smooth Cayenne and MD2 at 2, 4 and 6 months. The results obtained showed no statistically significant difference in plant mass between hybrid H4 (2675 g) and cultivars MD2 (2645 g) and Smooth Cayenne (2763 g) after 6 months of planting. The fresh and dry mass of the stems of these three varieties were also statistically identical. Hybrid H4 leaf D fresh mass was very low (55 g) at six months of planting compared to the two cultivars (73 g each). Hybrids H2 and H3 at this same period gave leaf masses of over 80 g. Regarding the characteristics assessed, hybrids H4 and H3 had much more conformity with cultivars Smooth Cayenne and MD2.

Background: Diabetes Mellitus has emerged as one of the most challenging public health problems in the 21st century, it is a serious public health problem that threatens the quality of life of patients which can lead to acute and chronic complications. This study, therefore, assessed knowledge and level of diabetes management compliance among clinic attendees at Jericho specialist hospital, Ibadan, Nigeria

Methods: A descriptive cross-sectional study that employed a two-stage sampling technique was designed to fill this gap. The records revealed that the ratio of males to females was 1:3, the respondents were stratified by gender, so the proportion of females and males selected was based on the aforementioned ratios.  Systematic random sampling was then used in selecting respondents who chose to participate in the study using the list of males and females in the hospital register who was at the clinic on the day of the interview as sampling frames. A pre-tested semi-structured questionnaire was used to obtain information on two hundred and twenty respondents. Knowledge scores of ≤7, >7 was rated poor and good respectively. Data were analyzed using descriptive and inferential statistics.

Results: The mean age was 49.7±10.29 years which many (72.2%) were female. Almost all the respondents (98.2%) had good knowledge of compliance with the management of diabetes. Many (74.1%) ascertained that they sometimes forget to take their diabetes drugs. Meanwhile, most (82.5%) reported that taking medication every day is a real inconvenience for some people as they could get annoyed about sticking to their blood glucose treatment plan.

Conclusion: There was generally good knowledge on the compliance to diabetes management which there is a need to consider the certain sociodemographic factors of the patients before recommending management.

Published: November 2021

Background: Visha (Poison) is a substance, which after entering the body, disturbs natural and physiological functions of body (i.e. Dosha, Dhatu, Mala). Due to its potency, it may potentially cause death in a relatively short period. A significant proportion of Indians live in villages distant from the city and work in agriculture with their lower extremities exposed. Snake-rat habitat is more prevalent in rice and sugarcane fields.

Aims and Objective: To study the efficacy of Sanjeevani Vati in common cobra venom poisoning and Russell’s viper venom as a first aid measure.

Materials and Methods: The preparation of Sanjeevani Vatiis carried out in Department of Rasashastra, Govt. Ayurved College, Nagpur and venom was collected from snake farm’, Haffkine Institute for Training Research and Testing, Mumbai. Animal Experiment for efficacy of Sanjeevani Vati as a first aid measure on Common cobra venom and Russell’s viper venom was carried out in National Toxicology Center (NTC) Pune.

Results: The results of survival period in Russell’s viper venom group were proved to be statistically significant. P value is 0.0055(Unpaired t-test; Two tail).But in results of Common Cobra venom, it was observed that there is no delay in appearance of paralysis, convulsion & survival period. In fact all these symptoms appear near about at same time, when Sanjeevani Vati was given orally after ingestion of Cobra Venom.

Conclusion: Sanjeevani Vati property is an ophidian. If you have Russell's viper venom, it is helpful as a first aid measure since it extends its life time. Poly Valent Anti snake venom serum does not interact with it (PVASVS).

Este artigo objetiva refletir sobre o feminismo negro no Brasil, trazendo algumas vozes teóricas que traçam um percurso desse movimento. Para tanto, duas escritoras contemporâneas farão coro à essas vozes. Verificaremos de que forma o canto libertário de Jarid Arraes ecoa em seus versos cordelianos bem como sob qual perspectiva a narrativa áspera de Miriam Alves aponta-nos caminhos para outros olhares sobre racismo, violência e sexismo. Dessa forma, tanto os versos de Arraes quanto a prosa de Alves são como uma “cusparada na cara” dos preconceitos e estereótipos criados contra a mulher negra.Palavras-chave: Feminismo negro.

Authors: Gonçalves Patricia Ivanca de Espíndola , Lyra Jorge , De Lucena Mota Mirella
Published: November 2021

Este estudo teve como objetivo analisar as ações de enfrentamento à violência contra as mulheres realizadas pela equipe multiprofissional da Secretaria da Mulher de Garanhuns (SecMul) e pelo Centro Especializado de Atendimento à mulher em situação de violência – Joana Beatriz de Lima e Silva (CEAM-JB). Trata-se de uma pesquisa que parte da perspectiva construcionista do conhecimento e das epistemologias feministas. A partir dos resultados, foi possível perceber que a SecMul e o CEAM-JB organizam as ações de enfrentamento a partir de três eixos: prevenção, atendimento e articulação intersetorial. No que se refere à prevenção, as profissionais relataram que esta se configura como a “porta de entrada” das usuárias no serviço. Em relação ao atendimento, as interlocutoras relataram dificuldades para escuta e intervenção das mulheres em situação de violência e, por isso, utilizam da discussão coletiva de alguns casos que mobilizaram a equipe. O uso de metodologias participativas nas ações de prevenção, as intervenções pautadas a partir de uma perspectiva de gênero e o fortalecimento de ações intersetoriais são elementos principais das ações de enfrentamento à violência contra as mulheres realizadas pela equipe multiprofissional da SecMul e do CEAM-JB.

A system for real‐time monitoring of breath‐hold via assessment of internal anatomy in tangential breast radiotherapy
Authors: Vasina Elena N. , Greer Peter , Thwaites David , Kron Tomas , Lehmann Joerg
Published: November 2021

The deep inspiration breath‐hold (DIBH) technique assists in sparing the heart, lungs, and liver during breast radiotherapy (RT). The quality of DIBH is currently assessed via surrogates which correlate to varying degrees with the patient's internal anatomy. Since modern linacs are equipped with an electronic portal imaging device (EPID), images of the irradiated anatomy streamed from EPIDs and analyzed in real time could significantly improve assessment of the quality of DIBH.

A system has been developed to quantify the quality of DIBH during tangential breast RT by analyzing the “beam's eye view” images of the treatment fields. The system measures the lung depth (LD) and the distance from the breast surface to the posterior tangential radiation field edge (skin distance, SD) at three user‐defined locations.

LD and SD measured in real time in EPID images of two RT phantoms showing different geometrical characteristics of their chest wall regions (computed tomography dose index [CTDI] and “END‐TO‐END” stereotactic body radiation therapy [E2E SBRT]) were compared with ground truth displacements provided by a precision motion platform. Performance of the new system was evaluated via static and dynamic (sine wave motion) measurements of LD and SD, covering clinical situations with stable and unstable breath‐hold. The accuracy and precision of the system were calculated as the mean and standard deviation of the differences between the ground truth and measured values.

The accuracy of the static measurements of LD and SD for the CTDI phantom was 0.31 (1.09) mm [mean (standard deviation)] and –0.10 (0.14) mm, respectively. The accuracy of the static measurements for E2E SBRT phantom was 0.01 (0.18) mm and 0.05 (0.08) mm. The accuracy of the dynamic LD and SD measurements for the CTDI phantom was –0.50 (1.18) mm and 0.01 (0.12) mm, respectively. The accuracy of the dynamic measurements for E2E SBRT phantom was –0.03 (0.19) mm and 0.01 (0.11) mm.

Published: November 2021

Objective

The study objective was to test the acceptability of a self‐management program (SMP) for adolescents with juvenile idiopathic arthritis (JIA) focused on disease information, self‐management, and social support needs.

Methods

This study was conducted using inductive qualitative methods to explore the acceptability of an in‐person/videoconference SMP. Two groups of four adolescents with JIA (mean age = 13.5, SD = 0.8) and two groups of pediatric rheumatology health care professionals (n = 4, n = 5) participated in four feedback sessions each. The SMP was presented to study participants, and feedback was provided on the content, format, and structure of the program. Thematic analysis was used to analyze the data.

Results

Adolescents felt that the content was appropriate and would be effective in supporting self‐management of their arthritis. Participants advised that the trustworthiness of the information would be increased if a rheumatology health care provider facilitated the session. Potential barriers to participation included distance and availability (weekdays and times), but the option for videoconference‐based participation was an appropriate solution to both of these issues. Minor changes were made to content and format, and required changes were made to address participant recommendations for improvement.

Conclusion

This study confirmed the acceptability of an in‐person/videoconference SMP for patients with JIA. Modifications were made to the SMP based on the focus group feedback, and future directions include a pilot randomized controlled trial to assess feasibility and preliminary effectiveness of the program.
Quantitative Determination of Contradictory Bandgap Values of Bulk PdSe2 from Electrical Transport Properties
Authors: Nishiyama Wataru , Nishimura Tomonori , Ueno Keiji , Taniguchi Takashi , Watanabe Kenji , Nagashio Kosuke
Published: November 2021

2D PdSe2, a Group 10 noble metal dichalcogenide, has been reported to have a strong thickness‐dependent bandgap energy, ranging from ≈1.6 eV (monolayer) to ≈0.05 eV (bulk) and a high photoresponsivity for bulk samples in the far infrared wavelength range of 10.6 μm. However, a middle bandgap of ≈0.5 eV has been contradictorily reported for bulk PdSe2 via optical absorption measurements. In this study, detailed electrical transport measurements are conducted to solve this contradiction. The key difference between narrow gap and middle gap semiconductors is the contribution of a depletion layer to the transfer characteristics. Hall measurements reveal intrinsic p‐type carrier densities of ≈1.9 × 1018 cm−3 at 300 K and the contribution of the depletion layer to the transfer characteristics for bulk PdSe2, suggesting a middle bandgap. Moreover, the maximum depletion width (WDm) is determined from top‐ and back‐gate coupling in dual gate transistors to be ≈17–18 nm. Based on the WDm – acceptor density diagram, the bandgap of bulk PdSe2 is quantitatively estimated to be ≈0.3 eV. Although this is not a desirable result from the viewpoint of far infrared material, it helps us to correctly understand the mechanism for the photoresponse of PdSe2.

Hyperbolic phonon polaritons (HPhPs) sustained in polar van der Waals (vdW) crystals exhibit extraordinary confinement of long‐wave electromagnetic fields to the deep subwavelength scale. In stark contrast to uniaxial vdW hyperbolic materials, recently emerged biaxial hyperbolic materials, such as α‐MoO3 and α‐V2O5, offer new degrees of freedom for controlling light in two‐dimensions due to their distinctive in‐plane hyperbolic dispersions. However, the control and focusing of these in‐plane HPhPs remain elusive. Here, a versatile technique is proposed for launching, controlling, and focusing in‐plane HPhPs in α‐MoO3 with geometrically designed curved gold plasmonic antennas. It is found that the subwavelength manipulation and focusing behaviors are strongly dependent on the curvature of the antenna extremity. This strategy operates effectively in a broadband spectral region. These findings not only provide fundamental insights into the manipulation of light by biaxial hyperbolic crystals at the nanoscale but also open up new opportunities for planar nanophotonic applications.

Understanding novel actuating materials which respond to a variety of stimuli is key in the development of micro/nanoscale robotics. In this work, the mechanism of actuation in nickel hydroxide/oxyhydroxide actuators by the intercalation/deintercalation of water is examined. This effect is studied under the stimuli of visible light, photoactuation, and by increased environmental temperature, thermoactuation. The photoactuation is modelled using a mechanical model, and it is demonstrated that the experimentally observed intrinsic strain can be achieved with a low deintercalation of water, around 1%. This low level of water exchange is supported by structural changes observed during heating using thin film X‐ray diffraction (XRD), as well as time of flight secondary ion mass spectrometry (ToF‐SIMS) by isotopic exchange using D2O. These results show the water intercalation hypothesis is both possible and measurable. Future development must take this mechanism into account when designing materials for improved actuation performance.

The resulting interfacial stress in heteroepitaxial nanocomplex usually has negligible influence on its performance, but at high pressures (HP) the effect can be significantly amplified. In order to unravel the underlying mechanism and search for high quality pressure sensors, a simple object is employed, NaErF4@NaLnF4 (Ln = Y, Lu, Gd) and its Tm3+‐doped derivatives, to comparatively study the effect of interfacial stress on upconversion (UC) luminescence. Specifically, the doping enhances greatly mechanosensitivity because of the anisotropic local geometry of the dopant ions of which the structural distortion is amplified by HP. The generated compressive strain does extend into the core as witnessed by the effect of tensile strain in the shell on the core and the fact that Lu‐shelled nanoparticles are the most sensitive to external force among Tm3+‐doped system. This compressive strain in concert with the external HP intensifies the coupling between Er3+ and Tm3+, making the attenuation of green UC emission more pronounced. The red to green UC emission ratio of this material, robust both in structural and optical properties, increases linearly with pressure in the range from ambient to 9 GPa. The study opens a new horizon for understanding the effect of interfacial stress on UC luminescence.

This study was designed to determine the influence of the thermal level and duration of chilling period on the initiation and progress of gonadogenesis and gametogenesis under controlled conditions in pikeperch (Sander lucioperca). A set of 120 fish was distributed into eight tanks (15 fish per tank). The effects of two temperatures (6 or 12°C) in combination with two durations of chilling period, either short (S; 75 days at 6°C and 125 days at 12°C) or long (L; 135 days at 6°C and 185 days at 12°C), were investigated for the effect on growth, gonadosomatic index (GSI), hepatosomatic index (HSI), gamete developmental stage and sex‐steroid levels (17 beta‐estradiol‐E2 and testosterone‐T). These zootechnical and physiological parameters were selected as they reflect the progressive advancement of gametogenesis in percids including pikeperch. The results show that the temperature did not affect the reproductive parameters but down‐regulated the HSI and the condition factor in females. In addition, the exposure to a longer chilling period, whatever the temperature, allowed for (1) further advancement of gonadogenesis in females (GSI = 6.5% vs. 11%), (2) further advancement of gametogenesis (0% vs. 60% of oocytes at late vitellogenesis, 15% vs. 80% of spermatozoa in males) and (3) the maintenance or increase of plasma sex steroids in both sexes (e.g. 10 ng/mL vs. 27 ng/mL of T in females). Together with already published data, these results suggest that, depending on the features of fish populations and photothermal programmes, the maintenance of temperature at either 6 or 12°C does not necessarily impact pikeperch gonad maturation. However, the duration of the chilling period is an important factor for the optimization of gonadogenesis and gametogenesis achievement before reproduction.

Intelligent response carriers have been developed and widely used in agriculture to improve pesticide utilization. However, there are few tailored response carriers that are targeting the cotton aphid pest. Based on the temperature‐dependent growth and reproduction of cotton aphids, we constructed a tailored temperature‐responsive star‐shaped polymer to achieve on‐demand controlled release of imidacloprid (IMI) to more effectively kill cotton aphids. In this work, a series of star‐shaped polymers based on β‐cyclodextrin (β‐CD), 2‐(2‐methoxyethoxy)ethyl methacrylate (MEO2MA), and tert‐butyl acrylate (tBA) were synthesized via atom transfer radical polymerization (ATRP). Next, β‐CD‐PMEO2MA (β‐CD‐P0) micelles were developed having different controlled release rates of IMI at different temperatures (14, 21, or 27°C) following the cotton aphid growth and reproduction cycle. At 21°C, the micelle underwent a phase transition from a solution state to a turbidity state. By inducing this structural change, release of IMI was increased to adapt to the reproduction of the cotton aphid population which is highest at 21–27°C. In vitro release experiments showed that 48% of IMI was released from β‐CD‐P0 after the phase transition temperature (PTT). An aqueous solution of the β‐CD‐P0 polymer micelle was stable at 4°C for at least 28 days. Therefore, this intelligent response release model has enormous potential as a novel carrier for various pesticides.
Insurrection in the U.S. Capitol: Understanding psychotic, projective and introjective group processes
Authors: Rudden Marie G.
Published: November 2021

Leader‐follower and intra‐group dynamics are analyzed for two large groups who participated in the January 6, 2021 attack on the U.S. Capitol building. Psychotic, projective and introjective defenses are seen to have increasingly developed within these groups in the months leading up to the Insurrection. These were amplified by three incendiary forces: escalating feelings of victimization, an undermining of a sense of truth and of trust in the national government, and an amplification of false messages by social media barrages. This exploration uses as data the multiple reports of journalists who witnessed the Capitol uprising or who conducted individual interviews with group members, as well as reports from the U.S. Department of Justice.

We report the synthesis and structural characterization of two coordination polymers (CPs), namely; [{Zn(L)(DMF)4} ⋅ 2BF4]α (1) and [{Cd(L)2(Cl)2} ⋅ 2H2O]α (2) (where L=N2,N6‐di(pyridin‐4‐yl)naphthalene‐2,6‐dicarboxamide). Crystal packing of 1 reveals the existence of channels running along the b‐ and c‐axis filled by the ligated DMF and lattice anions, respectively. Whereas, crystal packing of 2 reveals that the metallacycles of each 1D chain are intercalating into the groove of adjacent metallacycles resulting in the stacking of 1D loop‐chains to form a sheet‐like architecture. In addition, both 1 and 2 were exploited as multifunctional materials for the detection of nitroaromatic compounds (NACs) as well as a catalyst in the ipso‐hydroxylation of aryl/heteroarylboronic acids. Remarkably, 1 and 2 showed high fluorescence stability in an aqueous medium and displayed a maximum 88% and 97% quenching efficiency for 4‐NPH, respectively among all the investigated NACs. The mechanistic investigation of NACs recognition suggested that the fluorescence quenching occurred via electron as well as energy transfer process. Furthermore, the ipso‐hydroxylation of aryl/heteroarylboronic acids in presence of 1 and 2 gave up to 99% desired product yield within 15 min in our established protocol. In both cases, 1 and 2 are recyclable upto five cycles without any significant loss in their efficiency.
The peaked spectrum and compact steep spectrum sources: Issues and opportunities
Authors: O'Dea Christopher
Published: November 2021

The peaked spectrum (PS) radio sources are sub‐kpc in size and have a peak in the radio spectrum. The compact steep specrum (CSS) sources range from about 1 kpc to an adopted upper limit on projected linear size of 20 kpc. Because of their galactic‐scale range of size, the PS and CSS radio sources interact strongly with the ISM of this host galaxy. This means that the PS and CSS sources can be a significant source of the AGN feedback. The PS and CSS sources are a key phase in radio source evolution. Yet, there is substantial uncertainty regarding the origin of these sources, their lifetimes, and their evolution. There are many interesting open questions regarding the PS and CSS radio sources. Here, in this short introduction to the topic, I focus on the origin stories for these sources and how progress might be made.
