New biostratigraphical data (calcareous nannofossils, ammonites) and Early to Late Barremian transition in the Urgonien Jaune facies and Marnes de la Russille complex of the Swiss Jura Mountains
Authors: De Kaenel Eric , Mojon Pierre-Olivier , Pictet Antoine
Published: December 2020

In the central Jura Mountains (Western Switzerland), the Urgonien Jaune (UJ) facies with the Marnes de la Russille beds (MRu) have provided very rich nannofloras associated with very rare Tethyan ammonites. A late Early Barremian nannoflora of the Mid-Barremian Event (MBE, following a regional tectonic event of an earliest Barremian synsedimentary tectonic crisis) was found in MRu of the lower UJ and includes 42 genera with 90 species. Among them, Biscutum jurensis De Kaenel, n. sp., Flabellites eclepensensis De Kaenel, n. sp., Palaeopontosphaera giraudii De Kaenel, n. sp., Rhagodiscus buisensis De Kaenel, n. sp., and Vagalapilla rutledgei De Kaenel, n. sp., are recognized as five new species. This nannoflora is a mixture of Boreal and Tethyan taxa with 20 nannofossil markers (Assipetra terebrodentarius, Broinsonia galloisii, Calcicalathina oblongata, Cyclagelosphaera rotaclypeata, Diloma placinum, Ethmorhabdus hauterivianus, Flabellites eclepensensis, Gorkaea pseudoanthophorus, Nannoconus abundans, Nannoconus pseudoseptentrionalis, Palaeopontosphaera giraudii, Palaeopontosphaera pinnata, Placozygus howei, Placozygus reticulatus, Reinhardtites scutula, Rhagodiscus buisensis, Rhagodiscus eboracensis, Tegulalithus septentrionalis, Tubodiscus jurapelagicus, Zeugrhabdotus moulladei) indicating very precisely the nannofossil Zones LK19 (Boreal)–NC5D (Tethyan) as well as the Elegans (Boreal) and Moutonianum (Tethyan) ammonite Zones of the latest Early Barremian. The ammonites in the basal UJ facies of Early Barremian age are reworked Lyticoceras claveli (Nodosoplicatum Zone, Early Hauterivian) and reworked Cruasiceras cf. cruasense (Sayni Zone, early Late Hauterivian), and Pseudometahoplites sp. juv. (Compressissima to Vandenheckii Zones, Early to Late Barremian transition) from the basal MRu. The new palaeontological and sequential results of this study allow a revision of previous data from Godet et al. (2010) precisely assigning a Barremian age to the MRu of the central Jura Mountains (Tethyan Compressissima to lower Sartousiana and Boreal uppermost Fissicostatum to middle Denckmanii ammonite Zones, Boreal LK20B-LK19-LK18 and Tethyan NC5D nannofossil Zones), within the Early to Late Barremian UJ (Tethyan Hugii to lower Sartousiana and Boreal Rarocinctum to middle Denckmanii ammonite Zones, Boreal LK20C to LK18 and Tethyan NC5C-NC5D nannofossil Zones) and below the Late Barremian Urgonien Blanc facies (Tethyan Sartousiana ammonite Zone).

A rational emotive behavior therapy-based intervention for binge eating behavior management among female students: a quasi-experimental study
Authors: Yang Jiwon , Han Kuem Sun
Published: December 2020

Background

Binge eating behavior is highly likely to progress to an eating disorder, with female students particularly at risk.

Objective

This study aimed to verify the effect of a binge eating behavior management program, based on rational emotive behavior therapy (REBT), on binge eating behavior and related cognitive and emotional factors among female college students.

Method

The study, conducted from November 1 to December 2, 2016, involved a pretest-posttest design and nonequivalent control group. The sample included 24 and 22 first- to third-year students, from a college in South Korea, in the experimental and control groups, respectively. Data were collected using self-esteem, covert narcissism, perfectionism, body dissatisfaction, anxiety, depression, and binge eating scales and analyzed via frequency analysis, χ2 tests, t tests, and analysis of covariance.

Results

The results indicated that the REBT-based binge eating behavior management program exerted positive effects on participants’ self-esteem, reducing covert narcissism, body dissatisfaction, anxiety, depression, and binge eating. However, there was no significant difference in perfectionism, although the experimental group’s mean score decreased from pretest to posttest.

Conclusions

Based on the results, the program was considered to be effective, and is expected to be useful in preventing the development of eating disorders among female college students by treating binge eating behavior and related cognitive and emotional factors. This intervention could ultimately contribute to the improvement of female college students’ health and quality of life.

For me, the SEG Annual Meeting is our Society's prime venue for sharing technology, learning about new products and services, meeting old friends, and forging new alliances. For SEG as an organization, it is not only all of those things but also the largest expense and the biggest revenue generator of the year. Therefore, as the transmission of COVID-19 increased, it was with considerable organizational anxiety that SEG moved from the traditional in-person convention, to a hybrid convention, to the fully digital convention held from 11–16 October 2020.

Although the complete assessment of the meeting will take some time for our organization to construct, I feel qualified to provide a limited assessment of the pros and cons from the perspective of researchers, academics, and students.
The value of geophysical data for geothermal exploration: Examples from empirical, field, and synthetic data
Authors: Trainor-Guitton Whitney
Published: December 2020

The value of information (VOI) metric requires geophysicists to clearly link their measurements to important subsurface parameters in geothermal exploration, such as temperature, permeability, and fluid information. The metric quantifies the increase in the expected (average) value outcome of a decision. The decision is made with a certain type of additional information, compared to if the decision was made without the information. VOI has challenges that are similar to those faced by machine learning enthusiasts. Labeled data sets are needed in which the labels are the decision variables and the features are the geophysical observables. This paper presents three examples of how the statistical relationship, or reliability, may be calculated for geothermal exploration applications. VOI provides a way to document successes and identify opportunities for improvement in derisking geothermal prospecting with geophysical information.

Improving prescribing of extended prophylaxis for venous thromboembolism at discharge in patients who underwent surgery for colorectal cancer
Authors: Ong Chea Tze , Leung Edmund , Shah Adarsh P
Published: December 2020

Aims/Background

Prophylaxis at discharge is important in mitigating venous thromboembolism events from colorectal cancer and major abdominopelvic surgery, both of which are risk factors for venous thromboembolism. Foundation doctors frequently rotate between departments, and so rely on departmental induction and/or handing down of knowledge to prescribe extended venous thromboembolism prophylaxis upon discharge.

Methods

A retrospective audit of all patients who underwent surgery for colorectal cancer at The County Hospital, Hereford, between 1 August 2018 and 31 August 2019, was undertaken to assess departmental compliance with guidance from the National Institute for Health and Care Excellence.

Results

A total of 181 patients underwent elective surgery and 29 patients had emergency surgery. The initial audit revealed a cyclical 4-monthly decline that coincided with foundation doctors' rotations. Six multidisciplinary interventions were implemented. Reaudit demonstrated 100% compliance with prescribing of extended venous thromboembolism prophylaxis at discharge. No venous thromboembolism events 30 days post operation were noted.

Conclusions

A multidisciplinary approach involving educating health professionals about the importance of extended venous thromboembolis prophylaxis in patients who have undergone surgery for colorectal cancer can be effective in improving compliance with prescribing practices at discharge.

Efficient generation of triangular optical pulses in an erbium-doped
chalcogenide fiber amplifier by exploiting the time transformation
technique
Authors: Chatterjee Roshmi , Basu Mousumi
Published: December 2020

The time transformation (TT) technique is used to study the nonlinear pulse reshaping towards triangular pulse (TP) generation by efficiently optimizing the pulse parameters in an erbium-doped chalcogenide fiber amplifier (EDCFA), for the first time, to the best of our knowledge. The effects of input chirp parameter, optical gain, and dipole relaxation time are also depicted in the context of TP generation. The results obtained from the TT approach when compared with that from the nonlinear Schrodinger equation show excellent agreement. The study also reveals that spectral pulse doubling can be achieved at a shorter length when a pre-chirped Gaussian pulse is propagated through the proposed EDCFA.

Published: December 2020

Children and adolescents commonly suffer from sleep and circadian rhythm disturbances, which may contribute to poorer mental health and wellbeing during this critical developmental phase. Many studies however rely on self-reported sleep measures. This study assessed whether accelerometry data collection was feasible within the school setting as a method for investigating the extent of sleep and circadian disruption, and associations with subjective wellbeing, in Scotland. Fourteen days of wrist-worn accelerometry data were collected from 69 pupils, aged 10–14 years. Objective measures of sleep timing, sleep duration and circadian rest-activity patterns were derived. Questionnaires assessed subjective sleep timing, depressive symptoms, and experiences of wearing the accelerometer. Pupils slept on average less than 8 hours per night, failing to meet standard age-specific recommendations. Sleep timing was later and duration longer on weekends compared to weekdays (B = 0.87, 95% confidence interval (CI) 0.70, 1.04; B = 0.49, 95% CI 0.29, 0.69), indicating social jetlag. Lower daytime activity was correlated with higher depressive symptoms (r = -0.84, p = 0.008). Compared to primary school pupils, secondary pupils had shorter sleep window duration and lower circadian relative amplitude. Over half of participants reported some discomfort/inconvenience wearing the accelerometer. These data highlight that inadequate sleep is prevalent in this sample of schoolchildren. Future, larger scale investigations will examine in more detail the associations between sleep, circadian function and physical activity with mental health and wellbeing.

Authors: Zhou Zhigang , Liu Yanyan , Yu Hao , Ren Lihua
Published: December 2020

The aims are to explore the construction of the knowledge management model for engineering cost consulting enterprises, and to expand the application of data mining techniques and machine learning methods in constructing knowledge management model. Through a questionnaire survey, the construction of the knowledge management model of construction-related enterprises and engineering cost consulting enterprises is discussed. First, through the analysis and discussion of ontology-based data mining (OBDM) algorithm and association analysis (Apriori) algorithm, a data mining algorithm (ML-AR algorithm) on account of ontology-based multilayer association and machine learning is proposed. The performance of the various algorithms is compared and analyzed. Second, based on the knowledge management level, analysis and statistics are conducted on the levels of knowledge acquisition, sharing, storage, and innovation. Finally, according to the foregoing, the knowledge management model based on engineering cost consulting enterprises is built and analyzed. The results show that the reliability coefficient of this questionnaire is above 0.8, and the average extracted value is above 0.7, verifying excellent reliability and validity. The efficiency of the ML-AR algorithm at both the number of transactions and the support level is better than the other two algorithms, which is expected to be applied to the enterprise knowledge management model. There is a positive correlation between each level of knowledge management; among them, the positive correlation between knowledge acquisition and knowledge sharing is the strongest. The enterprise knowledge management model has a positive impact on promoting organizational innovation capability and industrial development. The research work provides a direction for the development of enterprise knowledge management and the improvement of innovation ability.

Authors: Gautam Vaishali , Bhardwaj Pankaj , Saxena Deepak , Kumar Nitesh , S. Dileepan
Published: December 2020

Background

Annually, in India, millions of dog bite cases occur; most of them are inflicted by a stray dog. There are over 25 million dogs in the country. The rate of stray dog vaccination is suboptimal in India. This study aims to develop an intervention strategy, using Intervention Mapping framework, tailored for the target community to achieve canine rabies controlled zone.

Methodology

This is an exploratory, cross-sectional study conducted at a tertiary care Medical Institute at Jodhpur, Rajasthan, India, from 2018–2019. The semi-structured, In-Depth Discussion was conducted with a multidisciplinary planning group comprising of members from veterinary, health, and administrative sectors. The In-Depth Discussion focused on knowledge regarding complete stray dog vaccination schedule, self-efficacy (to prevent dog bites), challenges, and barriers faced by residents to achieve canine rabies controlled zone. Further, discussion with veterinary stakeholders focused on challenges faced for rigorous implementation of stray dog vaccination and sterilization.

Results

In-Depth Discussion revealed the following challenges: Lack of participation by the study population for canine vaccination, incomplete knowledge about annual canine vaccination schedule, lack of understanding of dog gestures, lack of infrastructure and resources at veterinary hospitals. The majority of the dogs in the study area were stray dogs that were partially or non-vaccinated and non-sterilized. An intersectoral collaboration was achieved between the community members, veterinary stakeholders both private and Non-Governmental organisations, and heath sector. Following which 35 (76.0%) stray dogs were vaccinated, and 17 (35.4%) were sterilized with community support. Burden of dog bite cases also decreased. The stray dog density map was prepared, and community engagement activity on dog gestures was conducted.

Conclusion

The present study demonstrates the feasibility of achieving canine rabies controlled zone. When implemented in a phase-wise manner across all Medical and Residential complex, this strategy would ensure achieving canine rabies controlled zone through multi-stakeholder engagement.

Aim

To determine the prevalence and causes of blindness, vision impairment and cataract surgery coverage among Rohingya refugees aged ≥ 50 years residing in camps in Cox’s Bazar, Bangladesh.

Methods

We used the Rapid Assessment of Avoidable Blindness (RAAB) methodology to select 76 clusters of 50 participants aged ≥ 50 years with probability proportionate to size. Demographic and cataract surgery data were collected using questionnaires, visual acuity was assessed per World Health Organization criteria and examinations were conducted by torch, and with direct ophthalmoscopy in eyes with pinhole-corrected vision <6/12. RAAB software was used for data entry and analysis.

Results

We examined 3,629 of 3800 selected persons (95.5%). Age and sex adjusted prevalence of blindness (<3/60), severe visual impairment (SVI; >3/60 to ≤6/60), moderate visual impairment (MVI; >6/60 to ≤6/18), and early visual impairment (EVI; >6/18 to ≤6/12) were 2.14%, 2.35%, 9.68% and 14.7% respectively. Cataract was responsible for 75.0% of blindness and 75.8% of SVI, while refractive error caused 47.9% and 90.9% of MVI and EVI respectively. Most vision loss (95.9%) was avoidable. Cataract surgical coverage among the blind was 81.2%. Refractive error was detected in 17.1% (n = 622) of participants and 95.2% (n = 592) of these did not have spectacles. In the full Rohingya cohort of 76,692, approximately 10,000 surgeries are needed to correct all eyes impaired (<6/18) by cataract, 12,000 need distance glasses and 73,000 require presbyopic correction.

Conclusion

The prevalence of blindness was lower than expected for a displaced population, in part due to few Rohingya being ≥60 years and the camp’s good access to cataract surgery. We suggest the United Nations High Commissioner for Refugees include eye care among recommended health services for all refugees with long-term displacement.
Data and documentaries: Methodological hybridizations in activism
Authors: Gutiérrez Miren
Published: December 2020

Hybridization permeates all fields of communication: documentaries are no exception. One example is The Left-to-Die Boat by Forensic Architecture (FA), an audio-visual account of how 63 refugees lost their lives in 2011 when their ship was adrift in the waters of Libya. The Left-to-Die Boat combines documentary techniques with data analysis and visualizations to expose a tragedy, change migration policies and sustain court cases. Based on critical data and documentary studies, this article inspects the methodological hybridization proposed by FA in six documentaries. The questions are: how does FA hybridize? What are the outcomes of this hybridization? What is hybridization today? The analysis links these documentaries’ characteristics with functions and outcomes, offering a taxonomy that can be employed beyond this study. The findings indicate that activism is taking multidimensional forms, blurring the boundaries separating documentaries, data science and art in search of impact.

The optimal control will aim to minimize the number of infected population and control measures. Numerical experiments will be performed to illustrate and compare the graph of Covid-19 spread model with and without control.
MODELING PREDICTIVE TRACKING CONTROL FOR MAX-PLUS LINEAR SYSTEMS IN MANUFACTURING
Authors: Aulia Lathifatul , Widowati Widowati , Tjahjana R. Heru , Sutrisno Sutrisno
Published: December 2020

Discrete event systems, also known as DES, are class of system that can be applied to systems having an event that occurred instantaneously and may change the state. It can also be said that a discrete event system occurs under certain conditions for a certain period because of the network that describes the process flow or sequence of events. Discrete event systems belong to class of nonlinear systems in classical algebra. Based on this situation, it is necessary to do some treatments, one of which is linearization process. In the other hand, a Max-Plus Linear system is known as a system that produces linear models. This system is a development of a discrete event system that contains synchronization when it is modeled in Max-Plus Algebra. This paper discusses the production system model in manufacturing industries where the model pays the attention into the process flow or sequence of events at each time step. In particular, Model Predictive Control (MPC) is a popular control design method used in many fields including manufacturing systems. MPC for Max-Plus-Linear Systems is used here as the approach that can be used to model the optimal input and output sequences of discrete event systems. The main advantage of MPC is its ability to provide certain constraints on the input and output control signals. While deciding the optimal control value, a cost criterion is minimized by determining the optimal time in the production system that modeled as a Max-Plus Linear (MPL) system. A numerical experiment is performed in the end of this paper for tracking control purposes of a production system. The results were good that is the controlled system showed a good performance.

Published: December 2020

Kawasan karst merupakan ekosisten unik dan dijumpai gua-gua yang merupakan objek wisata yang potensial untuk dikembangankan. Salah satu kawasan wisata gua yakni Kali Suci Caving dan Tubing. Kelompok Sadar Wisata Desa Pacarejo (KSWDP), Kecamatan Ponjong, Kabupaten Gunungkidul mengelola Kali Suci Caving dan Tubing (KSCT) sejak tahun 2012. Untuk merespon keinginan pengunjung area wisata  maka perilaku manejemen pengelola dan perilaku pengunjung sebaiknya dikaji namun sedikit sekali pengelola area wisata mengkaji hal tersebut. Bagaimana KSWDP tersebut mengelola KSCT untuk merespon keinginan pengunjung dilakukan kajian perilaku pengelola dan perilaku pengunjung. Bauran pemasaran diaplikasikan pada kajian ini. Parameter yang dikaji yakni produk yang ditawarkan pengelola wisata kepada pengunjung, penentuan harga tiket dan penilaian pengunjung terhadap harga tiket, dan jenis promosi yang dilaksanakan oleh pengelola. Tokoh kunci dan responden yang diwawancarai yakni: Kepala Desa Pacarejo, Ketua KSWDP, dan pemandu wisata.   Data bauran pemasaran tersebut dianalisis dengan pendekatan kualitatif sedangkan untuk mengetahui perilaku pengunjung  dilakukan survei terhadap 72 orang responden dan dianalisis dengan pendekatan kuantitatif. Hasil penelitian menunjukkan bahwa: 1). Objek Wisata Kali Suci merupakan objek wisata minat khusus yang terdiri dari gua, di dalamnya terdapat sungai bawah tanah yang memiliki daya tarik untuk caving dan tubing dengan menghabiskan waktu sekitar 35 – 40 menit. Untuk meningkatkan kepuasan pengunjung, maka 1) secara fisik objek wisata KSCT perlu diperpanjang ke arah hulu Sub DAS Kali Suci, sehingga waktu pengunjung untuk menikmati wisata caving dan tubing menjadi lebih lama, 2). Harga tiket kegiatan rekreasi sebesar Rp. 80.000,-/orang dan dikatakan wajar oleh seluruh pengunjung yang diwawancarai, sesuai dengan jasa wisata yang ditawarkan, dan 3). Promosi telah dilakukan oleh pengelola area wisata Kali Suci melaui media sosial, biro travel, dan melalui pengunjung yang pernah mengunjungi Kali Suci, namun demikian jumlah pengunjung mulai tahun 2016 mengalami penurunan.  Menurut pengelola KSCT, penurunan jumlah pengunjung akibat dari Badai Cempaka yang terjadi pada tahun 2017. Di sisi lain, jumlah kunjungan wisata di Kabupaten Gunungkidul sebagai daerah semestanya memengalami kenaikan sejak tahun 2008–2017. Oleh karena itu, pengelola KSCT perlu memahami lingkungan bisnis pariwisata dan perilaku pengunjung objek wisata minat khusus yang memiliki segmen pasar: petualang yang sebagian besar berumur muda, dan berpendidikan. Promosi perlu difokuskan pada segmen pasar tersebut. Di samping penguasaan  caving dan tubing, pemandu wisata perlu dibekali pengetahuan tentang pembentukan dan ekosistem gua, sehingga dapat menjelaskan secara komprehensif tentang ekosistem gua tersebut.

Lobster air tawar (Cherax quadricarinatus) merupakan salah satu udang air tawar yang sudah dikembangkan sejak tahun 2000. Karakteristik yang signifikan terkait kelangkaan stok benih adalah sifat kanibalisme. Sifat kanibal biasanya muncul pada stadia benih terutama saat moulting. Upaya yang dapat dilakukan dengan penambahan triptofan dalam pakan. Triptofan merupakan asam amino esensial yang diduga dapat berperan sebagai pengendali kanibal. Penelitian ini bertujuan untuk mengkaji penambahan triptofan dalam pakan buatan terhadap tingkat kanibalisme dan pertumbuhan lobster air tawar. Udang uji yang digunakan adalah lobster air tawar dengan bobot 1,47±0,16 g/ekor. Pakan diberikan dengan metode relative feeding rate yaitu 3%. Benih dipelihara pada ember padat tebar 1 ekor/L. Penelitian ini dilakukan dengan metode eksperimental menggunakan rancangan acak lengkap (RAL) dengan 4 perlakuan dan 5 ulangan. Perlakuan A, B, C, dan D adalah pakan buatan dengan dosis triptofan masing-masing sebesar 0, 1, 2, dan 3%. Variabel yang diamati meliputi total konsumsi pakan (TKP), efisiensi pemanfaatan pakan (EPP), protein efisiensi rasio (PER), laju pertumbuhan relatif (RGR), kelulushidupan (SR) dan tingkat kanibalisme (TK). Hasil penelitian menunjukkan bahwa triptofan pada pakan memberikan pengaruh nyata (P<0,05) terhadap TKP, EPP, PER, RGR, SR, dan TK. Perlakuan B (1%) menghasilkan nilai tertinggi pada TKP yaitu sebesar 16,54±0,91g, EPP 74,54±3,77%, PER 2,12±0,11%, RGR 1,99±0,16%, dan SR 82±8,37%, TK 10,00±7,07%. Dosis optimum untuk menekan tingkat kanibalisme dan meningkatkan pertumbuhan berkisar antara 1,55-1,61%. Parameter kualitas air selama penelitian berada pada kisaran yang layak untuk kehidupan benih lobster air tawar. Disimpulkan bahwa penambahan dosis triptofan dalam pakan buatan mampu menekan tingkat kanibalisme dan meningkatkan pertumbuhan benih lobster air tawar secara maksimal.

Authors: Oliveira Fernando Ailton Castellani de , Brandalise Nilson
Published: December 2020

Companies are increasingly seeking methods to eliminate costs, and one of the big problems in companies is rework. The objective of this study was to identify costs and rework through the application of quality tools, allied to the Monte Carlo method (MMC), comprising the productive process of tire retreading, through an exploratory study. The applied methodology was in a tire retreading industry, located in the southern Fluminense region, in the state of Rio de Janeiro. One can conclude from the use of quality tools that the main failures within the process were the vulcanization, bonding and scarification / repair and also analyze by the Monte Carlo method the costs presented in the tire reform process through 5000 interactions. Through the tools, we can quantify the failures occurred in each stage. The main contribution of this work is the identification of the costs caused by the rework in the tires of automobiles and of load.

Constant raising the requirements for logistics service of end-consumer expand sales markets and economic relationships that are formed under conditions of uncertainty and instability of the environment, leading to the need to consider not only the logistics system of internal factors but also external. This issue is especially important for Commonwealth of Independent States that rebuilt to a market economy. Nowadays, the grocery logistics network distribution system that would fit for end-consumer and logistics systems owner simultaneously have not fully developed. On the one hand, consumers are looking for minimal cost, which can be provided by direct logistic channels, but minimal cost do not give flexibility in quantity and volumes or other services. On the other hand, the multilevel system provides high level of service and diversity in channel, but products are more expensive in it. Finding the balance between rational price and level of service for end-consumer and logistics system profits in period is been up-today issue in consumer-oriented logistics. The development of mechanisms makes it possible to assess the scale of the rational use of direct and multi-level logistics for the distribution of material flows, which was demonstrated with the numbering of participants in the logistics system in the current situation (external and internal factors). The paper considers the functioning of the system for delivering goods on a direct and multilevel distribution channel. An integrated approach to evaluate the efficiency of the functioning of the logistics system and the consumer had been used.

Published: December 2020

The purpose of this study was to investigate the influence principals’ relationship management (RM) on the organizational commitment (OC) of secondary school teachers in county governments in Kenya as moderated by teachers’ self-efficacy. This study hypothesized that principals’ RM has no significant relationship on the teachers’ OC. Survey research design was employed to establish the relationship between principals’ RM and teachers’ OC. Simple random sampling was used to draw a sample of 120 principals and 480 teachers from Nairobi, Machakos, Kajiado, and Kiambu counties in Kenya. The method of data collection was through the use of questionnaires. This study established that principals’ RM was a significant predictor of teachers’ OC. The study also established that teachers’ self-efficacy moderated the relationship between principals’ RM and teachers’ OC and that self-efficacy had positive influence on teachers OC. The study recommends that Teachers’ Service Commission (teachers’ employer) should put more emphasize on training of RM among principals in secondary schools in Kenya. This study makes useful contribution in the advancement of knowledge on the effects of principals’ RM on teachers’ OC in Kenya.

The study investigates the joint market efficiency hypothesis of the OPEC countries by obtaining monthly stock price data from seven OPEC countries from January, 2005 to April, 2016.  The study confirms the risk-return tradeoff in the OPEC stock markets.  While most relationships are positive only a pair of country shows strong negative association   Results of both parametric and nonparametric tests indicate that all OPEC members’ monthly stock return, except Qatar, are not weak-efficient. This implies that not all OPEC stock markets are efficient.  Meanwhile, the study finds that current monthly stock return of one country member can be predicted using the historical monthly price movement of another OPEC member.  As a whole, the monthly stock price of OPEC countries are not jointly weak efficient.  Recommendations were offered based on these important discoveries.

Published: December 2020

Introduction: Theory and research suggest the need to expand research on emotion regulation (ER) within borderline personality disorder (BPD). This research examined the relations of BPD symptoms to interpersonal (venting, reassurance-seeking) and socially-oriented (social comparison) ER strategies (in addition to acceptance and avoidance), and explored the role of trait social comparison orientation (SCO) in these relations.

Methods: In Study 1, a nationwide community sample of women completed questionnaires. In Study 2, a university sample of young women completed questionnaires and an online social interaction task (following which they reported on the strategies they used to regulate emotions during the task).

Results: Results revealed significant indirect relations of BPD symptoms to venting and reassurance-seeking through trait SCO, reassurance-seeking and social comparison through upward SCO, and the in-vivo use of downward social comparison and avoidance strategies during the social interaction task through upward SCO.

Discussion: Results highlight the relevance of trait SCO (particularly upward SCO) to socially-oriented ER strategies among women with heightened BPD symptoms.
Causal Evidence for a Double Dissociation between Object- and Scene-Selective Regions of Visual Cortex: A Preregistered TMS Replication Study
Authors: Wischnewski Miles , Peelen Marius V.
Published: December 2020

Natural scenes are characterized by individual objects as well as by global scene properties such as spatial layout. Functional neuroimaging research has shown that this distinction between object and scene processing is one of the main organizing principles of human high-level visual cortex. For example, object-selective regions, including the lateral occipital complex (LOC), were shown to represent object content (but not scene layout), while scene-selective regions, including the occipital place area (OPA), were shown to represent scene layout (but not object content). Causal evidence for a double dissociation between LOC and OPA in representing objects and scenes is currently limited, however. One TMS experiment, conducted in a relatively small sample (N= 13), reported an interaction between LOC and OPA stimulation and object and scene recognition performance (Dilks et al., 2013). Here, we present a high-powered preregistered replication of this study (N= 72, including male and female human participants), using group-average fMRI coordinates to target LOC and OPA. Results revealed unambiguous evidence for a double dissociation between LOC and OPA: relative to vertex stimulation, TMS over LOC selectively impaired the recognition of objects, while TMS over OPA selectively impaired the recognition of scenes. Furthermore, we found that these effects were stable over time and consistent across individual objects and scenes. These results show that LOC and OPA can be reliably and selectively targeted with TMS, even when defined based on group-average fMRI coordinates. More generally, they support the distinction between object and scene processing as an organizing principle of human high-level visual cortex.

SIGNIFICANCE STATEMENTOur daily-life environments are characterized both by individual objects and by global scene properties. The distinction between object and scene processing features prominently in visual cognitive neuroscience, with fMRI studies showing that this distinction is one of the main organizing principles of human high-level visual cortex. However, causal evidence for the selective involvement of object- and scene-selective regions in processing their preferred category is less conclusive. Here, testing a large sample (N= 72) using an established paradigm and a preregistered protocol, we found that TMS over object-selective cortex (lateral occipital complex) selectively impaired object recognition, while TMS over scene-selective cortex (occipital place area) selectively impaired scene recognition. These results provide strong causal evidence for the distinction between object and scene processing in human visual cortex.
