Published: April 2022

With the tendency toward economic and strategy decoupling between China and the United States and amidst the anti-globalization trend, enterprises are facing unprecedented challenges and opportunities. In this study, we reveal how the agile intuition (AI) of top managers with respect to the external environment affects enterprise innovation behavior (IB) based on the cognition–behavior framework. Strategic learning (SL) is considered a moderator, and knowledge sharing (KS) is considered a mediator. The survey sample consists of 305 managers from 47 enterprises in China during the COVID-19 period. The empirical results show that top management agile intuition significantly promotes enterprise IB; knowledge sharing (KS) partially mediates the relationship between top manager AI and enterprise IB; and SL suppresses the promotion effect of top manager AI on enterprise IB to a certain extent, hindering blind innovation. In a surprising result, we find that strategic guidance by an external consultant does not significantly affect the enterprise IB in China.
The impact of climate change on economic output across industries in Chile
Authors: Hernandez Karla , Madeira Carlos
Published: April 2022

Using region-industry panel data for Chile over the period 1985 to 2017, we find no effect of precipitation changes on GDP and a negative impact of higher summer temperatures on Agriculture-Silviculture and Fishing. An increase of one Celsius degree in the month of January implies a 3% and 12% GDP reduction in Agriculture and Fishing, respectively. There is also a negative effect of higher temperatures in January on Construction and Electricity, Gas, and Water. Our analysis suggests that climate change did not have a big impact on the Chilean economy during this period. Stress test exercises that select only the negative and statistically significant coefficients imply that the Chilean GDP would fall between -14.8% and -9% in 2050 and between -29.6% and -16.8% in 2100, according to our model.

Published: April 2022

While a substantial amount of research has focused on the abuse of opioids and cannabinoids in human populations, few studies have investigated accidental poisoning events in pet populations. The objective of this study was to identify whether poisoning events involving opioids and cannabinoids clustered in space, time, and space-time, and compare the locations of clusters between the two toxicants. Data were obtained concerning reports of dog poisoning events from the American Society for the Prevention of Cruelty to Animals’ (ASPCA) Animal Poisoning Control Center (APCC), from 2005–2014. The spatial scan statistic was used to identify clusters with a high proportion of these poisoning events. Our analyses show that opioid and cannabinoid poisoning events clustered in space, time, and space-time. The cluster patterns identified for each toxicant were distinct, but both shared some similarities with human use data. This study may help increase awareness to the public, public health, and veterinary communities about where and when dogs were most affected by opioid and cannabinoid poisonings. This study highlights the need to educate dog owners about safeguarding opioid and cannabinoid products from vulnerable populations.
Selection and validation of reference genes for quantitative real-time PCR of Quercus mongolica Fisch. ex Ledeb under abiotic stresses
Authors: Zhan Hao , Liu Hanzhang , Wang Tianchong , Liu Lin , Ai Wanfeng , Lu Xiujun
Published: April 2022

Quercus mongolica Fisch. ex Ledeb is the main species of coniferous and broadleaved mixed forests in northeast and north China, which has high ornamental, economic, and ecological value. The appropriate reference genes must be selected for quantitative real-time PCR to reveal the molecular mechanisms of stress responses and their contribution to breeding of Q. mongolica. In the present study, we chose 11 candidate reference genes (TUA, CYP18, HIS4, RPS13, ACT97, TUB1, UBQ10, UBC5, SAND, PP2A, and SAMDC) and used four programs (GeNorm, NormFinder, BestKeeper, and RefFinder) to assess the expression stability of the above genes in roots, stems, and leaves under five abiotic stress factors (cold, salt, drought, weak light, and heavy metal). The findings revealed that under various experimental environments, the most stable genes were different; CYP18, ACT97, and RPS13 ranked the highest under most experimental environments. Moreover, two genes induced by stress, CMO and P5CS2, were chosen to demonstrate the reliability of the selected reference genes in various tissues under various stress conditions. Our research provides a significant basis for subsequent gene function studies of Q. mongolica.

Published: April 2022

Background

While institutional series have sought to define the optimal strategy for drainage of pericardial effusions, large-scale comparisons remain lacking. Using a nationally representative sample, the present study examined clinical and financial outcomes following pericardiocentesis (PC) and surgical drainage (SD) in patients admitted for pericardial effusion and tamponade.

Methods

Adults undergoing PC or SD within 2 days of admission for non-surgically related pericardial effusion or tamponade were identified in the 2016–2019 Nationwide Readmissions Database. Multivariable logistic and linear models were developed to evaluate the association between intervention type and outcomes. The primary outcome of interest was mortality while secondary endpoints included reintervention, periprocedural complications, hospital length of stay (LOS), hospitalization costs and 30-day non-elective readmission.

Results

Of an estimated 44,637 records meeting inclusion criteria, 28,862 (64.7%) underwent PC while the remainder underwent SD for initial management of pericardial effusion or tamponade. PC was associated with significantly increased odds of in-hospital mortality, reintervention and 30-day readmission relative to SD. PC was also associated with greater odds of cardiac complications but lower odds of infection, respiratory failure and blood transfusions compared to SD. Although PC was associated with shorter index hospital length of stay and costs, the two strategies yielded similar 30-day cumulative costs.

Conclusion

Management of pericardial effusion with PC is associated with greater odds of mortality, reintervention and 30-day readmission but similar 30-day cumulative costs compared to SD. In the setting of adequate hospital capability and operator expertise, SD is a reasonable initial treatment strategy for pericardial effusion.

Published: April 2022

The Atlantic Forest harbors 7% of global biodiversity and possesses high levels of endemism, but many of its component taxa remain unstudied. Due to the importance of tropical forests and the urgency to protect them, there is a compelling need to address this knowledge gap. To provide more information on its arthropod fauna, a Malaise trap was deployed for 12 months in a semi-degraded area of the southern Upper Paraná ecoregion of the Atlantic Forest. All specimens were DNA barcoded and the Barcode Index Number (BIN) system was employed to assign each specimen to a species proxy. DNA barcodes were obtained from 75,500 arthropods that included representatives of 8,651 BINs. Nearly 81% of these BINs were first records, highlighting the high rates of endemism and lack of study of arthropods from the Atlantic Forest. Diptera was the most abundant order, followed by Hemiptera, Lepidoptera and Hymenoptera. Diptera was also the most species-rich order, followed by Hymenoptera, Lepidoptera, and Coleoptera, a result consistent with studies in other biogeographic regions. Insects were most abundant in winter and most diverse in autumn and winter. This pattern, however, was caused mainly by the dynamics of dipteran diversity as other orders differed in their seasonal variation. The BIN composition of the insect community varied sharply through the year and also differed between the two consecutive summers included in the sampling period. The study of the 38 commonest BINs showed that seasonal patterns of abundance were not order-specific. Temperature had the strongest impact on seasonal abundance variation. Our results highlight the striking and understudied arthropod diversity of the highly fragmented Atlantic Forest, the predominance of dipterans, and the fact that abundance and richness in this insect community peak in the coolest months. Standardized studies like this generate fast and reliable biodiversity inventories and unveil ecological patterns, thus providing valuable information for conservation programs.

Published: April 2022

Background

The coronavirus disease 2019 (COVID-19) pandemic may have a potentially serious effect on mental health and increase the risk of anxiety, depression, and post-traumatic stress disorders in people. In this study, we aimed to determine the prevalence of psychological illness and the impact of the COVID-19 pandemic on the Libyan population’s mental health.

Method

A cross-sectional survey, conducted in both online and paper modes and consisting of five sections, was completed in more than 30 cities and towns across Libya. The first section consisted of questions on basic demographic characteristics. The second section contained a survey related to the lockdown status, activities, related stress levels, and quarantine. The third section comprised the self-administered 9-item Patient Health Questionnaire (PHQ-9). The fourth section contained the 7-item Generalized Anxiety Disorder Scale (GAD-7), and the fifth section contained the Impact of Event Scale-Revised (IES-R).

Result

Of the 31,557 respondents, 4,280 (13.6%) reported severe depressive symptoms, with a mean [standard deviation (SD)] PHQ-9 score of 8.32 (5.44); 1,767 (5.6%) reported severe anxiety symptoms, with a mean (SD) GAD-7 score of 6 (4.6); and 6,245 (19.8%) of the respondents reported post-traumatic stress disorder (PTSD), with a mean (SD) score of 15.3 (18.85). In multivariate analysis, young age, being female, unmarried, educated, or victims of domestic violence or abuse, work suspension during the pandemic, and having increased workload, financial issues, suicidal thoughts, or a family member with or hospitalized due to COVID-19 were significantly associated with a high likelihood of depressive and anxiety symptoms, as well as PTSD. Internal displacement due to civil war was also associated with PTSD.

Conclusion

To our knowledge, this is the first study to analyze the psychological impacts of the COVID-19 pandemic and civil war in Libya. Further study on the development of strategies and interventions aimed at reducing the mental disease burden on the Libyan population is warranted.
What would reduce caesarean section rates?—Views from pregnant women and clinicians in Ireland
Authors: Gallagher Louise , Smith Valerie , Carroll Margaret , Hannon Kathleen , Lawler Denise , Begley Cecily
Published: April 2022

Background

Caesarean section rates continue to rise in most parts of the world. While CS is a lifesaving procedure there is evidence that, beyond a certain threshold, CS rates may contribute to increased maternal and perinatal morbidity. This study aimed to elicit the views of pregnant women’s and clinicians’ on how CS rates might be reduced.

Methods

Pregnant women and their partners, and clinicians working with pregnant women in a maternity hospital in the Republic of Ireland of Ireland, were invited to participate in focus groups. Eligibility criteria included all women attending antenatal classes and clinicians working with pregnant women. A convenience sample was used and interviews were audio recorded, transcribed, and analysed using thematic analysis.

Results

Four focus group interviews were conducted with 30 clinicians and 15 pregnant women and two partners participated in three focus groups. A further two women were interviewed individually. Participants expressed a view that rising CS rates were impacted by a societal perception that CS had become a ‘normal mode of birth’. Suggestions for reducing CS rates were offered by clinicians and pregnant women and their partners.

Conclusions

Clinicians and pregnant women consider that CS rates can be reduced if a shared philosophy supporting normal birth is prioritised alongside adequate resourcing. Women and their partners also believe that enhanced communication with clinicians is central to reducing CS rates.

Published: April 2022

Background

Elevated rheumatoid factor (RF) levels and systemic immune activation are highly prevalent during chronic hepatitis C virus (HCV) infection. Direct-acting antiviral (DAA) therapy has been associated with normalization of various soluble immune activation parameters. Whether the RF levels relate to soluble immune activation markers during chronic HCV infection, and over what time frame RF levels normalize during and after DAA treatment is unknown and was investigated here.

Methods

In a longitudinal study, plasma and serum was obtained from HCV infected RF positive (RF+) and RF negative (RF-) participants. The levels of RF, HCV RNA and soluble markers of inflammation were determined before (week 0), during (weeks 4, 8 and 12) and after (week 24) treatment with HCV DAA therapy. In a subset of RF+ participants, the analysis was extended to over 70 weeks after therapy initiation. Hepatic and other clinical parameters were determined at baseline (week 0) in all participants.

Results

Before therapy, transient elastography (TE) score was greater in RF+ compared to RF- HCV infected participants, while the systemic levels of soluble inflammatory markers were comparable. Following DAA therapy initiation, HCV RNA levels became undetectable within 4 weeks in both the RF+ and RF- groups. RF levels declined in the first 6 months in most RF+ persons but most commonly remained positive. The levels of some soluble inflammatory markers declined, mainly within 4 weeks of DAA therapy start, in both the RF+ and RF- groups. The baseline (week 0) TE score correlated with RF levels before, during and after DAA therapy, while plasma IL-18 levels correlated with RF level after DAA therapy.

Conclusion

During chronic HCV infection, TE score is elevated in RF+ HCV infected individuals and factors other than HCV viremia (including liver stiffness or fibrosis and select markers of inflammation) likely contribute to persistence of RF after treatment of HCV with DAA.
An improved multi-view attention network inspired by coupled P system for node classification
Authors: Liu Qian , Liu Xiyu
Published: April 2022

Most of the existing graph embedding methods are used to describe the single view network and solve the single relation in the network. However, the real world is made up of networks with multiple views of complex relationships, and the existing methods can no longer meet the needs of people. To solve this problem, we propose a novel multi-view attention network inspired by coupled P system(MVAN-CP) to deal with node classification. More specifically, we design a multi-view attention network to extract abundant information from multiple views in the network and obtain a learning representation for each view. To enable the views to collaborate, we further apply attention mechanism to facilitate the view fusion process. Taking advantage of the maximum parallelism of P system, the process of learning and fusion will be realized in the coupled P system, which greatly improves the computational efficiency. Experiments on real network data sets indicate that our model is effective.
Machine learning-based modeling of acute respiratory failure following emergency general surgery operations
Authors: Hadaya Joseph , Verma Arjun , Sanaiha Yas , Ramezani Ramin , Qadir Nida , Benharash Peyman
Published: April 2022

Background

Emergency general surgery (EGS) operations are associated with substantial risk of morbidity including postoperative respiratory failure (PRF). While existing risk models are not widely utilized and rely on traditional statistical methods, application of machine learning (ML) in prediction of PRF following EGS remains unexplored.

Objective

The present study aimed to develop ML-based prediction models for respiratory failure following EGS and compare their performance to traditional regression models using a nationally-representative cohort.

Methods

Non-elective hospitalizations for EGS (appendectomy, cholecystectomy, repair of perforated ulcer, large or small bowel resection, lysis of adhesions) were identified in the 2016–18 Nationwide Readmissions Database. Factors associated with PRF were identified using ML techniques and logistic regression. The performance of XGBoost and logistic regression was evaluated using the receiver operating characteristic curve and coefficient of determination (R2). The impact of PRF on mortality, length of stay (LOS) and hospitalization costs was secondarily assessed using generalized linear models.

Results

Of 1,003,703 hospitalizations, 8.8% developed PRF. The XGBoost model exhibited slightly superior discrimination compared to logistic regression (0.900, 95% CI 0.899–0.901 vs 0.894, 95% CI 0.862–0.896). Compared to logistic regression, XGBoost demonstrated excellent calibration across all risk levels (R2: 0.998 vs 0.962). Congestive heart failure, neurologic disorders, and coagulopathy were significantly associated with increased risk of PRF. After risk-adjustment, PRF was associated with 10-fold greater odds (95% confidence interval (CI) 9.8–11.1) of mortality and incremental increases in LOS by 3.1 days (95% CI 3.0–3.2) and $11,900 (95% CI 11,600–12,300) in costs.

Conclusions

Logistic regression and XGBoost perform similarly in overall classification of PRF risk. However, due to superior calibration at extremes of risk, ML-based models may prove more useful in the clinical setting, where probabilities rather than classifications are desired.
Winter cover crops increased nitrogen availability and efficient use during eight years of intensive organic vegetable production
Authors: White Kathryn E. , Brennan Eric B. , Cavigelli Michel A. , Smith Richard F.
Published: April 2022

Efficient use of nitrogen (N) is essential to protect water quality in high-input organic vegetable production systems, but little is known about the long-term effects of organic management on N mass balances. We measured soil N and tabulated N inputs (organic fertilizers, compost, irrigation water, atmospheric deposition, cover crop seed, vegetable transplant plugs and fixation by legume cover crops) and exports in harvested crops (lettuce, broccoli) over eight years to calculate soil surface and soil system N mass balances for the Salinas Organic Cropping Systems study in Salinas, CA. Our objectives were to 1) quantify the long-term effects of compost, cover crop frequency and cover crop type on soil N, cover crop and vegetable crop N uptake, and yield, and 2) tabulate N balances to assess the effects of these factors on N export in harvested crops, soil N storage and potential N loss. Results show that across all systems only 13 to 23% of N inputs were exported in harvest. Annual compost applications increased soil N stocks but had little effect on vegetable N uptake or yield, increasing the cumulative soil system N balance surplus over eight years by 999 kg ha-1, relative to the system receiving organic fertilizers alone. Annually planted winter cover crops increased N availability, crop uptake and export; however, biological N fixation by legumes negated the positive effect of increased harvest exports on the balance surplus in the legume-rye cover cropped system. Over eight years, rye cover crops improved system performance and reduced the cumulative N surplus by 384 kg ha-1 relative to the legume-rye mixture by increasing N retention and availability without increasing N inputs. Reduced reliance on external compost inputs and increased use of annually planted non-legume cover crops can improve efficient N use and cropping system yield, consequently improving environmental performance.

Although efficacious vaccines have significantly reduced the morbidity and mortality of COVID-19, there remains an unmet medical need for treatment options, which monoclonal antibodies (mAbs) can potentially fill. This unmet need is exacerbated by the emergence and spread of SARS-CoV-2 variants of concern (VOCs) that have shown some resistance to vaccine responses. Here we report the isolation of five neutralizing mAbs from an Indian convalescent donor, out of which two (THSC20.HVTR04 and THSC20.HVTR26) showed potent neutralization of SARS-CoV-2 VOCs at picomolar concentrations, including the Delta variant (B.1.617.2). One of these (THSC20.HVTR26) also retained activity against the Omicron variant. These two mAbs target non-overlapping epitopes on the receptor-binding domain (RBD) of the spike protein and prevent virus attachment to its host receptor, human angiotensin converting enzyme-2 (hACE2). Furthermore, the mAb cocktail demonstrated protection against the Delta variant at low antibody doses when passively administered in the K18 hACE2 transgenic mice model, highlighting their potential as a cocktail for prophylactic and therapeutic applications. Developing the capacity to rapidly discover and develop mAbs effective against highly transmissible pathogens like coronaviruses at a local level, especially in a low- and middle-income country (LMIC) such as India, will enable prompt responses to future pandemics as an important component of global pandemic preparedness.

Published: April 2022

A presente pesquisa pretende compor um processo analítico que envolve o conceito de EDS e encontra representatividade junto à UNESCO e o documento referente a Década para o Desenvolvimento Sustentável (2005-2014), nesse contexto acreditamos que a EDS associa-se ao conceito de ciência régia (DELEUZE, GUATTARI, 2012). O debate aqui encabeçado considera como elemento analítico o texto literário “Leônia” presente no livro Cidades Invisíveis de Ítalo Calvino, cujos habitantes vivem assombrados pelos dejetos do tempo passado. A investigação parte dos estudos de Michel Foucault (2015) com base na problematização e conta com o apoio do Grupo de Estudos Educação, Cultura, Ambiente e Filosofia (GEECAF) da FURG. Nosso interesse é identificar elementos da ciência régia focalizada na certeza e na norma que se desdobra no âmbito curricular, por outro lado, apostamos na Educação Ambiental como potência para criar e habitar as ruínas de nosso tempo e compor outras educações ambientais possíveis.

La geografía y la historia natural en México. Producción de conocimientos y aplicaciones tecnocientíficas, 1795-1934 contribuye al examen de las prácticas científicas vinculadas con la geografía y la historia natural desarrolladas por científicos, ingenieros y funcionarios mexicanos y extranjeros, que tuvieron implicaciones epistémicas, sociales, económicas y políticas durante las postrimerías del régimen colonial y después de la Independencia. Como resultado de aquéllas, se generaron campos disciplinares y conocimientos sobre el territorio y los recursos naturales, que se expresaron en productos científicos, desarrollos tecnológicos y aplicaciones prácticas. Esta obra presenta nueve capítulos que abordan la conformación de comunidades intelectuales que dotaron a la República Mexicana de un dinamismo científico similar al de otros países europeos y americanos. La geografía y la historia natural fueron disciplinas de especial interés para los grupos en el poder y la sociedad en general, pues se consideraba que la investigación racional del territorio y los recursos naturales garantizarían el progreso material y la consolidación del Estado. De ahí que desde 1821 ambas ciencias descollaron en los proyectos políticos, económicos, educativos, industriales y culturales en los niveles regional y nacional.

PSİKODİNAMİK YAKLAŞIMA GÖRE İNSAN DAVRANIŞININ İNCELENMESİ
Authors: YILDIRIM Oğuzhan , KUMCAĞIZ Hatice
Published: April 2022

Felsefeden ayrılıp bağımsızlaşan Psikoloji biliminin amacı insan davranışını araştırmak olmuştur. Psikanalizin kurucusu Sigmund Freud ruhsal sorunların kökenindeki psikolojik etmenlere ve bilinçdışının rolüne dikkat çekmiştir. Freud’un ardından gelen birçok kuramcı Psikanalitik bakış açısını benimsemiş ancak ortaya koydukları eleştiri ve katkılar sonucunda kendi kuramlarını oluşturmuşlardır. Psikodinamik kuramın başlıca temsilcileri Sigmund Freud, Carl G. Jung, Alfred Adler, Karen Horney, Erich Fromm, Harry S. Sullivan ve Erik H. Erikson’dur. Psikodinamik yaklaşımın benimsediği determinizm (nedensellik) kavramına göre insan davranışının altında mutlaka bir neden yatmaktadır. Buna göre hiçbir davranış, duygu ve düşünce rastgele olarak meydana gelmez. Dolayısıyla insan davranışının sonuçlarına bakarak davranışın nedenlerine de ulaşılabilir. Bu doğrultuda bu araştırmada insan davranışının psikodinamik temellerinin ve nedenlerinin incelenmesi amaçlanmıştır. İnsan davranışının psikodinamik temelleri arasında Freud’un topografik modelinde yer alan bilinç, bilinçdışı, bilinç öncesi kavramları, yapısal kişilik modelinde yer alan id, ego, süperego (altbenlik, benlik, üstbenlik) kavramları, güdülenme, dürtü, gereksinim, engellenme, ruhsal örselenme, kaygı ve savunma mekanizmalarının yer aldığı görülmüştür.

Authors: ŞEN Ceylan , AY Zeynep
Published: April 2022

This research aims to present gifted and talented students’ views regarding STEM education and STEM disciplines in engineering design-oriented integrated STEM activities. The research was modeled as a case study, using a qualitative research design, and was conducted with seven 7th grade students, who were getting support education at Science and Art Center. Individual interviews were conducted to reveal the views and definitions of students about STEM disciplines before STEM activities. During implementation process, ten-week STEM activities were conducted with the students. After STEM activities, individual interviews were held with students and student views on STEM disciplines and STEM education were revealed. Observation forms and STEM activity booklet as documents were used during the STEM activities to support the interview data. Data that was collected was analyzed through content analysis. In this study, it was seen that gifted and talented students STEM disciplines separately from each other and independently from real-life situation, however after STEM education, they were able to make interdisciplinary associations and associate them with other disciplines and real life. In line with the findings, it was concluded that STEM education is effective in defining STEM disciplines and in providing interest and motivation for STEM disciplines.

The trait of self-control is receiving growing attention as it leads to plenty of positive outcomes. Besides, there are so many scales based on different theoretical approaches in the literature. In this study, we aimed to adapt two important self-control scales, namely the Dispositional Self-Control Scale (DSC; Ein-Gar & Sagiv, 2014), and Desire for Self-Control Scale (DSCS; Uzie & Baumeister, 2017) into Turkish. In this context, we evaluated factorial validity, reliability coefficients (Cronbach α and McDonald's ω), discriminant, and convergent validity of these scales among college students sample. We also tested gender differences between men and women on self-control scores for two scales. Overall findings demonstrated that DSC, and DSCS had satisfactory psychometric properties for utilization such as acceptable fit indices, a high level of reliability coefficients, and good discriminant and convergent validity. We also discussed the implications of findings and future research.

Latar belakang: Beberapa faktor yang memengaruhi produktivitas kerja guru yaitu makanan yang dikonsumsi dan status gizi. Konsumsi yang perlu diperhatikan adalah konsumsi makan siang dan jajanan.Tujuan: Menganalis hubungan konsumsi makan siang dan jajanan terhadap produktivitas kerja dan status gizi guruMetode: Penelitian dilakukan pada bulan Juni-Oktober 2021 di SMK Pelita Ciampea Bogor. Desain penelitian ini adalah cross sectional dengan melibatkan 75 orang guru sebagai responden. Variabel yang diteliti meliputi karakteristik responden (usia, jenis kelamin, Pendidikan terakhir, dan lama bekerja), asupan makan siang dan jajanan, produktivitas kerja, dan status gizi guru. Analisis data menggunakan uji korelasi Spearman dengan tingkat kepercayaan 95%.Hasil: Rerata usia guru 40 tahun, sebagian besar berpendidikan sarjana, dan rata-rata lama bekerja selama 11 tahun. Sebagian besar guru belum memenuhi asupan makan siang dan jajanan sesuai kebutuhan yang dianjurkan. Sebagian besar guru memiliki produktivitas kerja yang sangat baik (86,7%). Sejumlah 48% guru mengalami gizi lebih, 46,7% gizi normal, dan 5,3% gizi kurang. Analisis korelasi Spearman menunjukkan tidak terdapat hubungan yang signifikan antara konsumsi makan siang dengan produktivitas kerja dan status gizi (p>0,05) Pada asupan jajanan, hanya konsumsi karbohidrat jajanan yang memiliki korelasi signifikan dengan produktivitas kerja (r=-0,259; p=0,025).Simpulan: Konsumsi karbohidrat dari jajanan memiliki korelasi yang signifikan dengan produktivitas kerja guru. Semakin tinggi konsumsi karbohidrat dari jajanan, maka semakin rendah produktivitas kerja guru.

The Ctenomys population from Anillaco, La Rioja Province, Argentina has been the subject of detailed studies of circadian rhythms, vocalization, ecology and spatial dynamics. However, the taxonomy and systematics of this population as well as populations of Ctenomys inhabiting Andean areas of this province is unknown. In this study, we present the phylogenetic relationship of the “Anillaco tuco-tuco” as well as of two other populations of Ctenomys, all distributed in the northern portion of La Rioja Province, Argentina. Based on molecular analyses and morphological comparisons, we reached to the conclusion that the “Anillaco tuco-tuco” population corresponds to the species Ctenomys famosus. In addition, an undescribed species, member of the “mendocinus” lineage of Ctenomys, is recognized in the Andean portions of the province.
Structural characterization of sodium and potassium 3-nitrohydrogenphthalate coordination polymers

Published: April 2022

The synthesis, crystal structures and properties of two alkali metal 3-nitrohydrogenphthalates obtained by a 1:2 reaction of M2CO3 (M = K or Na) with 3-nitrophthalic acid (LH2) are reported. In the anhydrous potassium coordination polymer [K(LH)] (LH = 2-carboxy-3-nitrobenzoate) 1, the K+ cation is bonded to nine oxygen atoms from six symmetry related (LH)– ligands resulting in a distorted {KO9} coordination polyhedron. Five of the six oxygen atoms including a nitro oxygen atom of the crystallographically unique 2-carboxy-3-nitrobenzoate are involved in metal binding. The μ6-bridging mode of (LH)– places the K+ cations into the layers of the two-dimensional (2D) coordination polymer. Each {KO9} polyhedron in 1 shares edges with two other polyhedra along the b and c axes. A low temperature structure redetermination of [Na(L#H)(H2O)3]·H2O (L#H = 2-carboxy-6-nitrobenzoate) 2 has revealed that the (L#H)− anion is bonded to the Na+ cation in a monodentate fashion via the carbonyl oxygen atom of the –COOH group and two of the three unique aqua ligands exhibit a bridging bidentate mode stabilizing a chain polymer. The structure of compound 2 thus consists of chains of edge-sharing {NaO6} octahedra. Thermal decomposition of 1 or 2 results in the formation of metal carbonate residues.
