Objective Patients with schizophrenia are characterized by compromised working memory (WM) performance and increased distractibility. Theta synchronization (especially over the frontal midline areas) is related to cognitive control and executive processes during WM encoding and retention. Alpha event-related desynchronization (ERD) is associated with information processing and attention. Methods Participants (35 patients and 39 matched controls) performed a modified Sternberg WM task, containing salient and non-salient distractor items in the retention period. A high-density 128 channel EEG was recorded during the task. Theta (4-7 Hz) and fast alpha (10-13 Hz) event-related spectral perturbation (ERSP) were analyzed during the retention and encoding period. Results Patients with schizophrenia showed worse WM performance and increased attentional distractibility in terms of lower hit rates and increased distractor-related commission errors compared to healthy controls. Theta synchronization was modulated by condition (learning vs. distractor) in both groups but it was modulated by salience only in controls. Furthermore, salience of distractors modulated less the fast alpha ERD in patients. Conclusions Our results suggest that patients with schizophrenia process salient and non-salient distracting information less efficiently and show weaker cognitive control compared to controls. Significance These differences may partly account for diminished WM performance and increased distractibility in schizophrenia.

Objectives To compare the clinical effectiveness of Hawley retainers (HRs) and modified vacuum-formed retainers (mVFRs) with palatal coverage in maintaining transverse expansion during a 12-month retention period. Materials and Methods Data were collected from postorthodontic treatment patients who met the inclusion criteria. A total of 35 patients were randomly allocated using a centralized randomization technique into either mVFR (n = 18) or HR group (n = 17). The outcome assessor and data analyst were blinded to the retention method. Dental casts of patients were evaluated at debond, 3 months, 6 months, and 12 months of retention. Intercanine width (ICW), interpremolar width (IPMW), interfirst molar mesiobuccal cusp width 1 (IFMW1), and interfirst molar distobuccal cusp width 2 (IFMW2) were compared between groups over time using mixed analysis of variance. Results No statistically significant differences were found between the two groups for ICW (P = .76), IPMW (P = .63), IFMW1 (P = .16), and IFMW2 (P = .40) during the 12-month retention period. Conclusions The null hypothesis could not be rejected. HR and mVFR had similar clinical effectiveness in the retention of transverse expansion cases during a 12-month retention period.

Objective The aim of this study was to assess to what extent simultaneously-obtained measures of listening effort (task-evoked pupil dilation, verbal response time [RT], and self-rating) could be sensitive to auditory and cognitive manipulations in a speech perception task. The study also aimed to explore the possible relationship between RT and pupil dilation. Design A within-group design was adopted. All participants were administered the Matrix Sentence Test in 12 conditions (signal-to-noise ratios [SNR] of -3, -6, -9 dB; attentional resources focussed vs divided; spatial priors present vs absent). Study sample Twenty-four normal-hearing adults, 20-41 years old (M = 23.5), were recruited in the study. Results A significant effect of the SNR was found for all measures. However, pupil dilation discriminated only partially between the SNRs. Neither of the cognitive manipulations were effective in modulating the measures. No relationship emerged between pupil dilation, RT and self-ratings. Conclusions RT, pupil dilation, and self-ratings can be obtained simultaneously when administering speech perception tasks, even though some limitations remain related to the absence of a retention period after the listening phase. The sensitivity of the three measures to changes in the auditory environment differs. RTs and self-ratings proved most sensitive to changes in SNR.

This paper provides an overview on how content can be managed with a blockchain or other distributed ledger technology (DLT), and what challenges need to be addressed in managing this content as part of transactions. Transactions on a blockchain may require supporting documents, for example, photos, reference documents, or actual contracts. As DLTs becoming an increasingly popular method to complete transactions and share information, several issues are arising that need to be addressed, such as: Where should this electronic content in documents be stored? Will the storage system have the features and functionality to properly manage this content through the "information lifecycle", including the retention and disposition of business records based on legal and regulatory requirements? The paper presents an overview of the emerging technology involved with distributed storage systems. It presents five solutions currently available, including their designs, how they secure and store files, and whether or not these files can be deleted in order to meet record disposition requirements and regulations. The discussion points out the need for alignment between multiple stakeholders and consortium members in a distributed ledger-based community with shared ecosystem scaling objectives. The challenges of scaling include the need to protect personal and sensitive information, especially when this information should normally be disposed after a record's retention period has ended.

We examined the effects of acute alcohol on eyewitness memory for a simulated armed robbery under laboratory conditions. Alcohol and placebo participants viewed a slide series showing a target male taking a laptop from a helpdesk assistant, either on loan or at gunpoint. Following a brief retention period, participants responded to “central” multiple-choice questions, about the target's actions face and clothing, and “peripheral” questions about other scene features. Alcohol participants shown the no-weapon scene displayed poorer peripheral memory than placebo controls, though alcohol did not impair peripheral memory among weapon scene viewers. Alcohol participants also showed a weapon focus effect, providing less accurate responses to central questions related to details about the target male than no-weapon controls. These findings are consistent with alcohol myopia theory and suggest intoxicated eyewitnesses may be more susceptible to weapon focus than sober counterparts.

Purpose Accountability in personnel records management is to a large extent, dependent on the availability of personnel records, there has been very little recognition of the need to address the management of personnel records as evidence for accountability either in relation to Freedom of Information (FOI) or Open Data. It is in this regard, therefore, the purpose of this study is to investigate the legal frameworks for personnel records management in support of accountability. The study used a descriptive design which combined both qualitative and quantitative approaches where both qualitative and quantitative information was involved in the study. Founded on the records life cycle and the records continuum, the study aimed to fulfil its main objective: establishing legal frameworks for personnel records management at Garissa County Government (GCG). Purposive sampling was used to select 11 Human Resource Management Officers (HRMO), 11 Personnel Record Management Officers (PRMO) and 11 Personnel Records Management Clerks (PRMC) and 55 staff members who made the total sample of 88 respondents. Data collected were analysed using descriptive statistics with the help of a Statistical Package for Social Scientists (version 17) was used to perform the analysis of quantitative data and presented through frequency tables, percentages, means and standard deviations. Results indicated that the County Government does not have legal frameworks in personnel records management. Several challenges were identified including lack of personal records management policy, lack of integrity, lose of documents/file and poor communication system. Generally, the study shows that legal frameworks in personnel records management is very important in accountability, therefore, GCG management needs to take measure to improve legal frameworks in personnel records management infrastructure and develop personnel records management policy. Design/methodology/approach The study was conducted using a descriptive design. This design ensures that data collected are analysed and findings are reported to establish a better understanding of a physical or social phenomenon. The descriptive design combined both qualitative and quantitative approaches where both qualitative and quantitative information was involved in the study. The study was conducted at the County Government of Garissa’s Head Quarters; it targeted staff involved in personnel records management. Garissa town was selected because it is a centre of various activities in County Government of Garissa. The target population comprising HRMO, PRMO, PRMC and staff from different ministries who depended on the personnel records management activities. Purposive sampling was used to select 11 HRMO, 11 PRMO, 11 PRMC and 55 staff members who made the total sample of 88 respondents from the population. Questionnaire method was used to collect data from HRMO, PRMO, PRMC and staff members quickly and give more freedom (in terms of time and flexibility) to the respondents. Interviews were used to obtain more in-depth information from the PRMO, HRMO and PRMC being the individuals’ in-charge of personnel records were to provide information on legal frameworks for personnel records management at GCG. Findings Lack of a policy signifies a lack of accountability and awareness of the personnel records management standards, meaning that the staffs are not aware of their responsibilities towards the management of the County’s records. This is therefore likely to contribute significantly to poor performance (Mampe and Kalusopa, 2012). This then puts the County in a precarious position regarding personnel records due to lack of guidelines on classing and handling of personnel records. Lack of a policy also shows a lack of commitment in the area, purporting neglect, where responsibilities are not clearly assigned and remain unclear. Weak institutional capacity and the absence of, for example, comprehensive personnel records management policies have been cited as one of the main causes of archival (as well as records management) underdevelopment in Africa (Ngulube and Tafor 2006). From the reactions of the existence of a draft policy, the staff indicated that it covered among other things: a policy statement, scope, definition of terms, applicable legislation and procedures, mail management encompassing both incoming and outgoing mail, filing classification, retention and disposal, as well as a statement of responsibilities. The study revealed that: personnel records management in Kenya operates under the framework and guidance of the Kenya National Archives and Documentation Services – KNADS which is supported by the Public Archives and Documentation Services Act, Cap 19. Besides the Cap 19, of 1965 of the Laws of Kenya, there are also various legislations that support the management of records in Kenya including the Ministry of State for Public Service (MSPS) (DPM) Circular on personnel records reference number DPM. 12/6A Vol. I (71) of 12th March 2008, the Records Management Procedure Manual for the Public Service, May 2010, prepared by the MSPS in consultation with the KNADS to provide guidelines and procedures to be followed in the day to day management of records in the public service. It is meant to be used alongside existing laws and legislation governing records management in the service. The effective utilization of the manual as stated by the Ministry is to contribute towards the government’s quest to achieve good governance and accountability in the Public Service. Adherence to the Manual is also meant to streamline personnel records management practice leading to effectiveness and efficiency in service delivery and the Government Financial Regulations and Procedures, chapter 23, section 4:2–5 give guidelines on the retention period for financial records. The management of personnel records is guided by various legislations and circulars such as Public Archives and Documentation Service Act, (Cap.19, Laws of Kenya) revised 1991, The Employment Act Chapter 226, revised in 1977 and 2007, The Regulation of Wages and Conditions of Employment Act Chapter 229, Income Tax Act Chapter 470 revised 1989, The National Social Security Fund Act Chapter 258 revised 1989, The Service Commission Act Chapter 185 of 1967 and DPM.12/6A VOL. I (71) dated 12th March 2008 on the destruction of personnel records. Compliance to all the above legal frameworks will ensure that personnel records management in support of accountability at GCG is achieved. Research limitations/implications The lack of effective personnel records management programme in a county agency was in itself non-conformity to the requirements and guidelines issued by the public services, thus leading to a lot of caution on how much could be revealed regarding the same. The focus of the study was on the assessment of paper-based and electronic personnel records management within the County Government. The assessment excluded other electronic records, such as online databases, with only personnel records being considered. Practical implications Nonexistence of personnel records management legal frameworks implies that the responsibilities for cooperate record management to GCG plans and guidelines of managing personnel records were inefficient. As a result of the absence of written personnel records management policy, there was also a lack of guidelines for appraisal, disposition and schedules of records. On legal frameworks for personnel records management at GCG, the findings revealed that there were many policies in GCG but personnel records management policy was missing which is very crucial. Record management policy will also enhance human resource management policy. The missing of the personnel records management policy reduces the accountability to people who deal with records management in general, increases lack of integrity and indicate that there is a presence of irrational decision. Social implications The missing of the personnel records management policy reduce the accountability to people who deal with records management, in general, increases lack of integrity and indicate that there is a presence of irrational decision. Originality/value The purpose of the study was to investigate the management of personnel records in support of accountability in devolved governments: A case of GCG.

Sleep has a beneficial effect on memory consolidation. However, its role in emotional memory is currently debated. Here, we investigate the role of sleep and a similar period of wakefulness on the recognition of emotional pictures and subjective emotional reactivity. Forty participants without any major physical, neurological or psychological condition were randomly assigned to the Sleep First Group or Wake First Group. The two groups underwent the encoding phase of an emotional images task with negative and neutral pictures at either 09:00 hours (Wake First Group) or 21:00 hours (Sleep First Group). Then participants performed an immediate recognition test (T1), and two delayed tests 12 hr (T2) and 24 hr (T3) later. Perceived arousal and valence levels were collected for each picture. Sleep parameters were recorded at participants' homes with a portable device. No differences were observed at T1, whereas at T2 the Sleep First Group showed a higher memory performance than the Wake First Group. At T3, performance decreased in the Sleep First Group (who spent the previous 12 hr awake), but not in the Wake First Group (who slept during the previous 12 hr). Overall, negative images were remembered better than neutral ones. We also observed a positive association between memory performance for negative items at the immediate test and the percentage of rapid eye movement sleep the night before the encoding. Our data confirm that negative information is remembered better over time than neutral information, and that sleep benefits the retention of declarative information. However, sleep seems not to preferentially improve emotional memory, although it may affect the encoding of negative information.

Background. Nowadays, the number of orthodontic care requests has increased significantly. The technical capabilities of orthodontics have improved exponentially with technological progress. The necessary care can now be provided at almost any age, and the need for aesthetic results has increased, as motivated by the mass media. As a result, patients have high demands to orthodontists. New technologies, such as cortical support, can solve dental abnormalities that previously could only be cured by surgery. However, maintaining high-quality results remains a challenge. Materials and methods. The objective parameters of orthodontic treatment were analyzed and compared with the subjective assessment of patients. Conclusion. The patients motivation, the desire to cooperate with the doctor, and a clear understanding of the treatment goals enable to obtain and retain high-quality results for a sufficiently long period of time.

The aims of this study were to measure treatment effects of aligner treatments in adult patients directly after treatment and the stability of these effects after a short-term retention period using the Peer Assessment Rating (PAR) Index.This double-center trial consecutively screened 98 adult patients of whom 33 patients were treated according to predefined inclusion and exclusion criteria. The study sample was shown to be representative for adult orthodontic reality with regard to gender, age, and distribution of malocclusion type. Malocclusion severity was rated by using the PAR Index measured at baseline (T0), after finishing orthodontic treatment with Invisalign® (T1; Align Technology Inc., Santa Clara, CA, USA) and after a mean retention period of 10 months (T2). Furthermore, to better understand the observed treatment modality, specific treatment characteristics were recorded and analyzed.The average PAR score at T0 was 22.18 (standard deviation [SD] ± 8.68). Posttreatment PAR score was 4.64 (SD ± 4.23) at T1 and was stable after a retention period of 10.07 months at T2 (SD ± 126.80 days; PAR 4.36, SD ± 3.93). All of the study cases showed a significant reduction of the total PAR score between T0 and T1 (p 0.001), but no further difference between T1 and T2 (PAR 4.64 vs. 4.36). Cases were either classified 'improved' (n = 23) or 'greatly improved' (n = 10); no case was classified into the third PAR Index category 'worse or no different'. On average, 72 aligners (SD ± 22) with 12 attachments per treatment (SD ± 4) were used to align teeth. Six patients needed a case refinement with a mean of 23 (SD ± 8) further aligners. The maximum number of needed ClinCheck® (Align Technology Inc., Santa Clara, CA, USA) treatment plan revisions was 18 (mean 7, SD ± 4).The detected improvement rate indicated a good standard of orthodontic treatment using aligners. Treatment effects were stable throughout a short-term retention period using a specific retention protocol. Effectiveness and stability were equally achieved in mild, moderate, and rather severe cases within this consecutive sample. A critical focus should be placed on accurate treatment planning in order to make tooth movements predictable, realistic, and stable.ZIELSETZUNG: Ziele dieser Studie waren zum einen die Behandlungseffektivität von Aligner-Behandlungen erwachsener Patienten mittels PAR(Peer-Assessment-Rating)-Index zu evaluieren und zum anderen die Stabilität dieser Behandlungseffekte zu untersuchen.Im Rahmen des Forschungsprojektes wurden 98 Patienten aus zwei Studienzentren konsekutiv gescreent, von denen 33 Patienten gemäß Ein- und Ausschlusskriterien rekrutiert werden konnten. Zahnfehlstellungen und Okklusionsabweichungen wurden mittels PAR-Index vor der entsprechenden Behandlung mit Invisalign® (Align Technology Inc., Santa Clara/CA, USA; T0), nach der aktiven kieferorthopädischen Behandlung (T1) und nach einer durchschnittlichen Retentionszeit von 10 Monaten (T2) ermittelt. Darüber hinaus wurden behandlungsspezifische Details vor Bestätigung erfasst und analysiert.Der durchschnittliche PAR-Summenwert zu T0 betrug 22,18 (Standardabweichung [SD] ± 8.68). Durch die kieferorthopädische Behandlung konnte dieser auf 4,64 (SD ± 4,23) zu T1 reduziert werden und blieb nach 10,07 Monaten zu T2 mit 4,36 stabil (SD ± 3,93). Bei allen Patienten wurde eine signifikante PAR-Index-Reduktion zwischen T0 und T1 (p 0,001) ermittelt. Zwischen T1 und T2 stellten sich keine signifikanten Veränderungen ein (PAR 4,64 vs. 4,36). Alle Patientenfälle wurden entweder als „improved“ (n = 23) oder „greatly improved“ (n = 10) eingestuft; keine Behandlung fiel in die dritte PAR-Index-Kategorie „worse or no different“. Durchschnittlich 72 Aligner (SD ± 22) mit 12 Attachments (SD ± 4) pro Behandlung wurden zur Begradigung der Zahnfehlstellungen und zur Einstellung der Okklusion genutzt. Sechs Patienten benötigten ein „case refinement“ mit durchschnittlich 23 (SD ± 8) Alignern. Sieben Revisionen des ClinCheck®-Behandlungsplans waren im Mittel vor entsprechender Bestätigung nötig (SD ± 4).Die vorliegende Studie zeigt, dass ein guter kieferorthopädischer Standard zusammen mit einer hohen Behandlungseffektivität durch Aligner-Behandlungen erzielbar ist. Die Behandlungseffekte waren innerhalb des untersuchten Zeitraums stabil. Ein besonderer Fokus sollte auf einer genauen digitalen Behandlungsplanung liegen, damit entsprechende Zahnbewegungen durch Aligner realistisch erzielbar und stabil sein können.

Background and Objectives: Retention is important stage of orthodontic treatment that preserves teeth in new positions. To make occlusion stable after orthodontic treatment, retention protocol is recommended. There is great variation among orthodontists regarding type, duration and strategies of retention following orthodontic treatment. Therefore, the aim of current survey was to identify the common retention procedures and to evaluate the results with similar studies conducted in different countries. Patients and methods: thirty five questionnaires in total with 20 questions were sent to all members of the Iraqi Orthodontic Society living in the Kurdistan region- Iraq. 35 orthodontists were responded to questionnaires. The questionnaire represents specific information about socio-demographic status of the respondents, selection of a retention system, details of commonly used retainers, the duration of the retention period, supervision of the retainers, instructions for patients. After receiving of the completed 35 questionnaires, the data were statistically analyzed. Results: Bonded retainer was the most common retainer for both maxillary (48.57%) and mandibular (65.71%) arches. 28.54% of the orthodontist ended bonded retention within 2 years, while 37% of orthodontists continued retention for more than 2 years. 77.14 % of participants advised to wear the removable appliances on a full-time basis during the first 6 months. Conclusion: All Orthodontists prescribe retention system. Fixed lingual retainer are the most common retainer among orthodontists. This is comparable to the most common prescribed type of retainers in other countries, but there are differences about duration and follow-up protocols.

Relevance. An open bite in children and adolescents makes up about 2-3% of all dentoalveolar disorders and is one of the most difficult pathological bites to treat. Aesthetic changes in children with vertical dislocation of the dentition are complicated by impaired functions of chewing, breathing and speech formation. The treatment of this pathology is complicated by an extensive list of etiological factors affecting the development of this pathology of the dentition. In most cases, after a successful hardware correction of an open bite, the pathology appears again after the completion of the active phase of orthodontic treatment.Purpose. To analyze the retention period in children and adolescents with vertical disocclusion of the dentition. Materials and methods. In order to analyze the retention period in children and adolescents with vertical disocclusion of the dentition, 17 children aged 5 to 15 years were taken for orthodontic treatment. Six of them showed vertical disocclusion (mild, 1 degree) of the dentition. 7 children and adolescents had vertical disocclusion of moderate severity. 4 patients aged 13-15 years had an open bite of a severe form. All patients underwent orthodontic treatment using removable and non-removable orthodontic appliances.Results. During the retention period in all patients of different groups specially made for this purpose were used demountable and non- removable devices , such as the Hawley device, medical devices in the inactivated state, non- removable wire retainers, single- jawed retention Kappa, retainers of their own design. ign. Examination of patients 6 and 12 months after the beginning of the retention period showed stability of the achieved therapeutic result in patients aged 5-12 years , and in patients of the older age group, the retention period was extended to 18-24 months due to the need to adapt bone structures.Conclusions. The analysis of the retention period of pediatric patients with vertical disocclusion of the dentition revealed a number of significant temporal differences. The average retention period in patients with open bite from the age of 5-12 years was 8-12 months. Its duration in patients aged 13-15 years was 15-24 months.

Field studies were conducted to evalaute the effectivess and active food-bait retention periods of 12 bait-stations with four stuffing materials and three stuffing techniques for 2 months in citrus, mango and guava orchards. GF-120 (commercially available food-bait) was used as standard. Results revealved that active retention-period of GF-120 was maximum in bait-station stuffed with three layers of jute (BSJ-3) after 6 weeks. BSJ-3 proved more effective for the application of food-bait followed by bait-station stuffed with two layers of jute (BSJ-2), that stuffed with three layers of coconut-husk (BSCH-3), that stuffed with two layers of foam (BSF-2), that stuffed with three layers of foam (BSF-3) and that stuffed with three layers of dried lufa (BSL-3) which were equally effective. The results also revealed that jute proved better stuffing material followed by foam, coconut-husk and dried-lufa while three-layer stuffing technique proved better followed by two-layers and one-layer for the preparation of bait-station for B. zonata. So three-layer stuffing of jute with GF-120 may be helpful in the development of bait station for the management of B. zonata.

Execution redundancy, defined as varying technique for a similar outcome, is a newer defined type of variability which opens new avenues of thinking about tennis training. 19 club-level tennis players were put through different training interventions: low variability where players had to rally to hit a target and maintain technique; and, high variability where players did the same but varied technique slightly. The high variability group improved after a retention period of 1 week in a test of accuracy (measuring average distance of 4 balls hit to a target) and success (measuring number of balls over the net and within a target radius of 500cm). The results suggest that that varying technique for a similar outcome improves performance more than low variability, possibly due mechanisms surrounding increased exploration creating better adapted motor patterns. The results show positive support for variability of this kind of training, but care needs to be taken to ensure that sound biomechanical and technical principles are observed.

Protecting working-memory content from distracting external sensory inputs and intervening tasks is an ubiquitous demand in daily life. Here, we ask whether and how temporal expectations about external events can help mitigate effects of such interference during working-memory retention. We manipulated the temporal predictability of interfering items that occurred during the retention period of a visual working-memory task and report that temporal expectations reduce the detrimental influence of external interference on subsequent memory performance. Moreover, to determine if the protective effects of temporal expectations rely on distractor suppression or involve shielding of internal representations, we compared effects after irrelevant distractors that could be ignored vs. interrupters that required a response. Whereas distractor suppression may be sufficient to confer protection from predictable distractors, any benefits after interruption are likely to involve memory shielding. We found similar benefits of temporal expectations after both types of interference. We conclude that temporal expectations may play an important role in safeguarding behaviour based on working memory – acting through mechanisms that include the shielding of internal content from external interference.

This retrospective cohort study analyzed the turnover rate and the risk factors of turnover among newly hired nurses at tertiary and secondary hospitals in South Korea. Using National Health Insurance Service data, this study created a cohort of 21,050 newly hired nurses across 304 hospitals in 2018, with a follow-up period of 18 months. Retention and turnover risk factors were analyzed at 6-month intervals. Differences in retention period according to hospitals’ organizational characteristics and nurses’ individual characteristics were analyzed using the chi-squared test. The likelihood of staying at work was analyzed using Kaplan–Meier survival curves with the log-rank test, and the hazard ratios of turnover at each retention period were analyzed using multilevel Cox proportional hazards analysis. The turnover rate of newly hired nurses within 1 year of employment was 26.4%, with 20.1% resigning within 6 months, and 6.3% resigning between 7 and 12 months. For all retention periods, turnover risk was associated with a higher bed-to-nurse ratio and older age. Higher standardized monthly income was associated with lower turnover between 13 and 18 months. Hospitals should develop nurse-retention strategies that consider risk factors for turnover. To reduce turnover, adequate nursing personnel should be maintained and fair compensation should be offered.
