Promises and perils of experimentation: The mutual internal validity problem
Authors: Lin Hause , Werner Kaitlyn M. , Inzlicht Michael
Published: March 2020

Researchers run experiments to test theories, search for and document phenomena, develop theories, or advise policymakers. When testing theories, experiments must be internally valid but do not have to be externally valid. However, when experiments are used to search for and document phenomena, develop theories, or advise policymakers, external validity matters. Conflating these goals and failing to recognize their tensions with validity concerns can lead to problems with theorizing. Experimenters in psychology should be aware of the mutual-internal-validity problem, long recognized by experimental economists. When phenomena elicited by experiments are used to develop theories that, in turn, influence the design of theory-testing experiments, experiments and theories can become wedded to each other and lose touch with reality. They capture and explain phenomena within but not beyond the laboratory. We highlight how triangulation can address validity problems by helping experiments and theories make contact with ideas from other disciplines and the real world.
Efficacy of Attachment-Based Family Therapy compared to Treatment as Usual for Depressed Adolescents in Community Mental Health Clinics
Authors: Waraan Luxsiya , Rognli Erling , Czajkowski Nikolai Olavi , Aalberg Marianne , Mehlum Lars
Published: March 2020

Background: Major Depressive Disorder (MDD) is a disabling mood disorder, profoundly affecting a large number of adolescent’s quality of life. To date, no obvious treatment of choice for MDD in adolescents is available and progress in the treatment of depressed adolescents will have important public health implications. Attachment-Based Family Therapy (ABFT), as the only empirically supported family therapy model designed to treat adolescent depression, aims to repair interpersonal ruptures and rebuild an emotionally protective parent-child relationship.Objective: To study the efficacy of ABFT compared with Treatment as Usual (TAU) delivered within child- and adolescent mental health services (CAMHS) to adolescents with MDD.Method: Sixty adolescents, aged 13-18 years, with MDD referred to two CAMHS were randomized to receive 16 weeks of ABFT or TAU. ABFT consisted of weekly therapy sessions (family/individual or both) according to the treatment manual. TAU was not monitored. Primary outcomes were clinician-rated (Hamilton Depression Scale, HAMD) and self-reported (Beck Depression Inventory-II, BDI-II) depressive symptoms assessed at baseline and post-treatment by blinded evaluators for HAMD and at baseline, and after 4, 6, 8, 10,12, 14, and 16 weeks for BDI-II. Analyses were performed according to intent-to-treat principles.Results: At post-treatment, clinician-rated remission rates on the HAMD (5 % in ABFT and 3.33% in TAU, p =1, OR=1.54, Fisher’s exact test) and self-reported symptoms of depression on the BDI-II did not differ significantly between groups (X2[2, N = 60] =0.06 , p = 0.97). In both treatment groups participants reported significantly reduced depressive symptoms, but the majority of adolescents were still in the clinical range after 16 weeks of treatment.Conclusion: In this sample of adolescents treated for MDD in community mental health clinics, ABFT was not associated with more favorable outcomes than TAU in terms of remission rates on clinician rated and self-reported depressive symptoms. Remission and response rates were low in both groups, suggesting a need for continued improvement of the treatment methods.
Toward a new comparative musicology
Authors: Savage Patrick E. , Brown Steven
Published: March 2020

We propose a return to the forgotten agenda of comparative musicology, one that is updated with the paradigms of modern evolutionary theory and scientific methodology. Ever since the field of comparative musicology became redefined as ethnomusicology in the mid-20th century, its original research agenda has been all but abandoned by musicologists, not least the overarching goal of cross-cultural musical comparison. We outline here five major themes that underlie the re-establishment of comparative musicology: (1) classification, (2) cultural evolution, (3) human history, (4) universals, and (5) biological evolution. Throughout the article, we clarify key ideological, methodological and terminological objections that have been levied against musical comparison. Ultimately, we argue for an inclusive, constructive, and multidisciplinary field that analyzes the world’s musical diversity, from the broadest of generalities to the most culture-specific particulars, with the aim of synthesizing the full range of theoretical perspectives and research methodologies available.
The emergence of deviance: Experiments testing the personal effects of violating a social norm
Authors: Gomila Robin , Paluck Elizabeth Levy
Published: March 2020

Social norms are such powerful drivers of human behavior that people conform to social norms even when they would prefer to violate them or when conforming is not in their personal material interest. Researchers have theorized that in these cases, people conform to avoid the social and psychological costs of deviance (e.g., guilt, self-deprecation, punishment). Notwithstanding the possible costs, people do decide to violate norms. We conducted two randomized experiments (N = 3,499) to explore the behavioral and psychological consequences of deviating from norms. Participants played behavioral games governed by norms of cooperation, without a mechanism for players to punish one another. Participants assigned to the treatment condition, unlike those in the control condition, were offered a monetary incentive to deviate from a strong norm of cooperation in one round of the game. Violating this norm significantly increased their propensity to violate other social norms in new settings involving new groups and new games (with no incentive to deviate). Post-treatment survey data suggest that violating norms causes people to depreciate their expectation of the costs associated with violation, but does not lead them to update their views of the self. Together, these results challenge and inform traditional views of deviance as personality or a stable individual motivation or trait, and suggest that deviance can emerge from an experience of deviance at any point in one's life.
Gender Differences in Russia’s Job Mobility and Its Rewards
Authors: Privalko Ivan
Published: March 2020

This article considers age and gender differences in the probability and consequences of job mobility; specifically firm exits and promotions in Russia. Russia's labour market should have high rates of job mobility, but we will show using IMF figures that the rate between 2011 and 2015 is on par with the 1980's. Beyond this, little is known about who is mobile and whether mobility has any impact on wages once the characteristics of movers are controlled for. In other words, we will ask whether job mobility is a sorting mechanism, or whether it has premiums in pay in and of itself. Results show a gender difference in the likelihood of firm exit but not in the likelihood of promotion. When several personal and job characteristics are held constant, young men and women have similar odds of promotion. However, promotions have a positive effect only on the wages of young women; young men's wages are not affected. On the topic of firm exits, when several personal and job characteristics are held constant, exit is more common among young men when compared to young women; this is also true of middle aged men and women. Further, young men see a significant decrease in wages following an exit, while young women are not affected by exit. These results are flipped for middle aged workers; middle aged men see no change in wages following an exit, but middle aged women see significant declines in wages following an exit. Using these results, the article shows that the early stages of a respondent's career are marked by periods of high mobility, which is similar to the experience of young workers in other countries. After this period, mobility becomes increasingly unlikely. Part of this result could stem from the premiums tied to promotion. Results help to understand processes of inequality in wages and conditions that occur due to sorting, and the importance of promotions (internal job changes with the same employer) as 'life chances' which improve earnings in the immediate sense. Gender differences in securing these life chances help to understand wider gender gaps in earnings, which emerge later.
Acute to random workload ratio is ‘as’ associated with injury as acute to actual chronic workload ratio: time to dismiss ACWR and its components
Authors: Impellizzeri Franco Milko , Wookcock Stephen , Coutts Aaron J. , Fanchini Maurizio , McCall Alan , Vigotsky Andrew David
Published: March 2020

Aim: The aim of this study is to assess the presence and implications of statistical artefacts created by a commonly used indicator of injury risk in both research and practice: the ratio between acute workload (AL) and chronic workload (CL), named ACWR. Methods: Using previously published data, we generated a contrived ACWR by dividing the AL by fixed and randomly generated CLs, and we compared these results to real data. Results: After reproducing the original analyses with only the ACWR showing effects compatible with higher injury risk (odd ratios, OR: 2.45, 95%CI 1.28 to 4.71), we demonstrated similar findings by dividing AL by the “contrived” fixed and randomly generated CLs: OR=1.95 (1.18 to 3.52) dividing by 1510 (average CL); and OR using random CL= 1.53 (mean), ranging from 1.16 to 2.07. Random ACWR calculated reducing the variance of the original AL further inflated the ORs (mean OR=1.89, from 1.42 to 2.70). ACWR causes artificial reclassification of players compared to AL alone. Finally, neither ACWR nor AL alone confer a predictive advantage to an intercept-only model, even within the training sample (c-statistic = 0.574/0.544 vs. 0.5 in both ACWR/AL and intercept-only models, respectively).Discussion: ACWR is a rescaling of the explanatory variable (AL, numerator), in turn magnifying its effect estimates and decreasing its variance despite conferring no predictive advantage. Other ratio-related transformations (e.g., reducing the variance of the explanatory variable and unjustified reclassifications) further inflate the OR of AL alone with injury risk. These results also disprove the etiological theory behind this ratio and its components. We suggest ACWR be dismissed as a framework and model, and in line with this, injury frameworks, recommendations, and consensus be updated to reflect the lack of predictive value of and statistical artefacts inherent in ACWR models.

Kurzfassung

Der große Erfolg des Wertstromdesigns basiert auch darauf, dass mit eindeutig formulierten Gestaltungsrichtlinien ein methodischer Weg zur optimalen Gestaltung der Produktion gewiesen wird. Dies ist bemerkenswert, da sich eine Systemgestaltung nicht deduktiv wie bei der Anwendung von Naturgesetzen ableiten lässt. Aufgrund ihrer hohen technikwissenschaftlichen Bedeutung sollte die Erstellung von Gestaltungsrichtlinien jedoch nicht freihändig erfolgen. Deshalb werden erstmals aus wissenschaftstheoretischer Perspektive Richtlinien zu deren Erstellung formuliert.

A case of alcohol-related emphysematous cystitis
Authors: Sancı A. , Aydoğ E. , Karaburun M.C. , Süer E.
Published: March 2020

Emphysematous cystitis (EC) is a very rare urinary tract infectious disease that can be fatal if not treated. In general, it frequently occurs in diabetic women and is thought to be associated with gas-producing bacteria. Type 2 diabetes mellitus, immunosuppression, drugs (mostly steroids), neurogenic bladder and instrumentation are the major risk factors of this type of infection.

We present a case of emphysematous cystitis in a 53-year-old male, in which the patient does not have any classical risk factors associated with EC other than alcohol consumption. To the best of our knowledge, the only case in the literature where this type of infection develops without a classical risk factor and negative urine culture. It is also one of the rare EC cases that may be associated with alcohol use.
Kidneys and microbiota
Authors: Semydotska Zh. , Chernyakova I. , Avdeyeva O.
Published: March 2020

The review article analyzes the results of studies of the bi-directional relationship of the intestinal microbiota and kidneys, the so-called colorenal interactive axis of interaction.  The intestinal microbiota is considered as a kind of organ that influences the brain, cardiovascular and immune systems, as well as the kidneys of the "host".  Short-chain fatty acids (SCFA) formed in the colon as the result of microbial metabolism from plant components of dietary fiber and acting as ligands for the olfactory receptor, paired G-proteins in the kidneys are recognized as the markers of this symbiosis.  With the help of modern omix technologies, the development of dysbiosis taking into account patients with chronic kidney disease (CKD) has been proved, which leads to the accumulation of precursors of uremic toxins, a decrease in the production of SCFA, which have nephroprotective properties and play a key role in energy homeostasis.

 Changes in the composition of the intestinal microbiota in CKD, an increase in the content of uremic toxins in the intestinal lumen contribute to the appearance of the “leaky” intestinal barrier syndrome, the movement of bacteria from the intestine into the general circulation, the development of systemic inflammation, oxidative stress, comorbidity, the progression of CKD, and an increase in mortality. Diets with restriction of protein and potassium quotas, violation of nutritional status lead to the development of dysbiosis in CKD.  A decrease in the diet of vegetables and fruit causes the expansion of bacteria producing uricase and urease, which are enzymes in the formation of uremic toxins and reduce the number and variety of bacteria producing short-chain fatty acids.  Potential targeted effects on the axis of “intestinal microbiota - chronic kidney disease” are being discussed: the use of a diet enriched in plant fibers, heat-treated, then chilled potatoes and rice as prebiotics (sources of resistant starch), nuts, plant seeds, and pro-, pre-, synbiotics, fecal transplantation.  Most of the proposed interventions in the structure and functions of the microbiota are not dangerous, side effects are minimal.

Differential Diagnosis of a Glenoid Cyst in Omarthrosis: Hemangioma of the Glenoid – Resection and Reconstruction Using Autologous Bone-Graft and Special Implant
Authors: Junker Marius , Kircher Jörn , Junker Marius , Farkhondeh-Fal Milad
Published: March 2020

Hemangiomas belong to the benign tumors, that can occur in any bone of the human body. The typical localization are the vertebral spine and the skull. There is no reported case of an intraarticular glenoidal hemangioma so far. The current paper presents a case of a 48-year-old female with joint pain that started 2 years before. The clinical manifestations included limited range of motion (ROM) and load dependent, non-load dependent and night pain. Roentgenogram and magnetic resonance imaging (MRI) of the left shoulder showed degenerative changes of the glenohumeral cartilage and a big (11.8mm x 10.3 mm) intraglenoidal mass affecting the joint line. The postoperative pathological diagnosis was that of a cavernous hemangioma. The aim of the present study was to present the imaging presentation of glenoidal hemangioma and to show therapeutic options in case of glenohumeral osteoarthritis (OA) with glenoidal bone loss due to hemangioma. In the present case no recurrence of the hemangioma and no complications of the implant in terms of loosening, infection or consisting were observed.
Cas particuliers de la prise en charge de la pathologie hémorroïdaire
Authors: Bessi G. , Higuero T.
Published: March 2020

La maladie hémorroïdaire a une prise en charge spécifique lorsqu’elle survient au cours de la grossesse, au cours d’une maladie inflammatoire chronique intestinale (MICI), si un traitement antiagrégant ou anticoagulant est en cours ou en cas d’antécédent d’irradiation pelvienne. Le traitement médical reste globalement inchangé (laxatifs, fibres…). Une attention particulière doit être portée sur la prescription des anti-inflammatoires non stéroïdiens et des antalgiques. Le traitement instrumental est contre-indiqué en cas de grossesse, MICI active, notamment avec une suppuration anopérinéale ainsi que chez un patient sous anticoagulant ou antiagrégant autre que l’aspirine. Le traitement chirurgical est envisageable sous aspirine, en cas de complication sévère résistante au traitement médical en cas de grossesse et en cas de MICI quiescente sans atteinte anorectale ni de suppuration. L’anticoagulation augmente le risque hémorragique postopératoire. Une radiothérapie pelvienne limite fortement la prise en charge thérapeutique.

oxidation instability. Chitosan is a biocompatible, biodegradable and non-toxic nanoparticles

forming polymer. Ultrasonication is a materials mixing technique under high vibration energy.

The ultrasonication time affects the particle size. The aim of this study was to determine the effect

of the ultrasonication time on physical characteristics of chitosan nanoparticles of suji (Pleomele

angustifolia) leaf ethanol extract and its physical stability after cycling test. Ethanol extract of suji

leaves (EEDS) was obtained by maceration using 70% ethanol. Chitosan EEDS nanoparticles were

made under ionic gelation method using an ultrasonication time of 3 minutes (FI), 6 minutes (FII),

and 9 minutes (FIII). The physical characterization of nanoparticles includes particle size,

polydispersity index, and zeta potential. Chitosan EEDS nanoparticles with the best physical

characteristics (FIII) were tested for stability using cycling test method. The data obtained were analyzed using the Anova statistical method with a 95% confidence level. The size of EEDS

chitosan nanoparticles (nm) was significantly different in all formulas, FI (374.47), FII (288.43),

and FIII (233.37). The polydispersity index of FI (0.38) and FIII (0.65) were significantly different,

while FII (0.41) was not significantly different. The zeta potential (mV) FI (51.70), FII (46.10), and

FIII (48.60) were not significantly different in all formulas. The physical characteristics of

Formula III after Cycling Test showed a particle size of 455.0 nm, a polydispersity index of 0.174,

and a zeta potential of 20.1 mV.

Magnetic levitation stages for planar and linear scan application with nanometer resolution1
Authors: Gloess Rainer , Goos Alexander
Published: March 2020

This article describes design rules for the magnetic constrains, the sensors and the controller for planar and linear stages for a scanning application with a resolution at nanometer level. The main advantage of magnetic levitated systems in relation to “standard” air bearing systems or mechanical guided systems is that they provide perfect cleanroom conditions. The other advantage is that there is no influence by inaccurate guiding. Because of closed-loop control in all 6 DOFs, there is also stationary accuracy and the highest repetition, which only depends on the resolution of the hysteresis-free sensor system. Most of industrial applications require free access to the movable top plate, requiring that all types of sensors should be placed below the platform. The main challenge for pushing the technology into “industry nanometer level” is how to get it to work with low-price distance sensors at nanometer resolution and a motion range of millimeters. A key point is the design of the controller structure for fast access of the actuators and many sensors, in case of the new planar system there are 24 coil pairs and 23 sensors working in the servo loop at 20 kHz.

Heavy Equipment Study Program, Jakarta State Polytechnic, has a warehouse that aims to store spare parts. These spare parts are used to meet the practical needs of students when lectures take place every semester. During this time, to lend and report spare parts, heavy equipment warehouse technicians still use forms and spare parts cards. This method is less effective when the stakeholders such as the Head of Workshop and Head of Study Program want to know the amount of spare parts stock that is still owned by the warehouse or data warehouse cannot be seen in real time. From these problems, the warehouse needs a way to speed up the process. One method that can be used to overcome this problem is to create a web-based system or application that can carry out an inventory, record, process, and report the spare parts data contained in the heavy equipment warehouse. This writing aims to design and build warehouse management applications for heavy equipment spare parts. So, with this web-based application, stake holders can view reports from the warehouse with the right target, accurate, and efficient.

The purpose of this study is to observe the pattern of fluid flow on a bulb making machine. The design problem of a mercury suction device is some of the mercury and the exhaust heat from the chimney is sucked in imperfectly towards the outlet. These imperfections occur due to the chimney design and power at the outlet fan. Variations in speed at the bulb-making machine outlet are the most effective looking simulation. CFD simulation is done using fluent ansys. The results of the simulation show the heat transfer phenomenon that occurred. At a speed of 6 m/s the maximum heat air produced is 30.5C. The speed variation in the most effective bulb making machine in this study is 15 m/s. because the surrounding air is almost close to initial temperature which is equal to 27.7C. Keep in mind that by increasing the speed value it will reduce the level of efficiency of the tool.
El mandato del hermano: antígona para la posmodernidad
Authors: Junco Ethel
Published: March 2020

De las muchas posibilidades de lectura de Antígona de Sófocles destacamos la naturaleza del conflicto trágico, que tiene sus raíces en valores anteriores al orden social establecido y que puede considerarse material útil para una refundación del estatuto político en la posmodernidad. A partir del comentario de texto señalamos que Antígona no atenta contra el orden social, sino que espera consolidarlo en un fundamento imperturbable; que encarna la crítica de la racionalidad instrumental, inaugurada por la sofística y reavivada sucesivamente en la modernidad; que afirma existencialmente una ética del amor fraterno como humanización del orden del universo. Proponemos ampliar la noción de hermano consanguíneo y extenderla a la idea de hermano como “el otro” en el marco de las sociedades posmodernas, espacios de intención multicultural, para tener un principio de rescate ético. En esta re-lectura se actualizan las nociones arcaicas de religiosidad, honra fúnebre y piedad familiar.
Alegres, libres y ruidosas: el espacio de lo soez y la trampa
Authors: Rodríguez F. Mario , Grandón O. Mauricio
Published: March 2020

Esta investigación busca dar cuenta de los espacios que habitan los personajes del cuento Alegres, libres y ruidosas (2015) de Pedro Juan Gutiérrez. Mediante los detalles que nos entrega el narrador, revisaremos los “operadores tonales”, estableciendo los enunciados descriptivos y los detalles inherentes a ellos, en cuanto a la composición de los personajes, así como el tipo de espacio en que se realizan, construyendo una identidad transgresora bajo la perspectiva de la poética de lo soez. En este sentido, los personajes serán “máquinas deseantes” que irrumpen en la realidad con un flujo sistemático de líquidos descompuestos (esperma) que arrastran residuos políticos, éticos y estéticos presentes en la Cuba contemporánea. Así, podríamos hablar de un sexo eminentemente político que no se presenta denotativamente en el cuento sino en las metáforas construidas por aquellos operadores que fijan el “tono” del relato (desenfadado, soez, libertario). Por último, postulamos que los detalles funcionan como “pistas” de una historia secreta (la historia de una trampa) que funciona bajo la historia visible que se narra en el cuento.

Una de las actividades profesionales que conllevan mayor compromiso con la historia del libro y la cultura en general consiste en rescatar autores y obras que, debido a posibles circunstancias: a los avatares del destino personal, o a las políticas editoriales del tiempo dentro del cual se gestan, o a la censura del poder religioso y político, o a una exclusión oficial merced los criterios discriminatorios de la literatura, o una simple jugarreta del infortunio que lleva a desaparecer a la obra en manuscrito, o, en el peor de los casos, a todo lo anterior; no han logrado el sitio que merecen en el gran panorama de la producción textual de la humanidad...
Vinculabilidad entre cuidado y mismidad en los §§. 39-42 de ser y tiempo: Heidegger y la mismidad del Dasein
Authors: Garrido-Periñán Juan José
Published: March 2020

Este artículo de investigación, desde los límites intrínsecos de los §§. 39-42 de la obra Ser y Tiempo, busca tematizar la mismidad del Dasein, en tanto saber de un sí-mismo no cósico que es correlato de la existencialidad y la facticidad de este ente, desde el modo de aparecer del existenciario cuidado, precisamente aquel encargado de dotar de unidad o totalidad estructural a los momentos constitutivos del ser-en-el-mundo como tal. Este análisis es ejercido con el fin de potenciar una posible vinculación entre cuidado y mismidad, donde, según parece, la mismidad se constituye como condición necesaria y suficiente del cuidado, responsable no solo de favorecer su unidad temática, sino el tránsito de la impropiedad a la propiedad existencial.

Published: March 2020

In the era of renewable energy development, one of the most important problems is the utilisation of residues of production of the so-called clean energy. In the case of biogas plants, the problem is the utilisation of waste after the anaerobic methane fermentation process of the organic substrate. One of the ways to use it is to produce organic and mineral fertilisers. However, the fertiliser plant may be exposed to a number of threats
that may prevent its functioning. To avoid this, the factors that carry the risk need to be identified. The purpose of the article is to identify external risk factors for a fertiliser plant based on digestate. The following types of risk were identified as a result of the research: risk of supplying fertiliser components of inadequate quality; risk of non-compliance with deadlines for the delivery of raw materials or their total absence; risk of the presence
of eggs of parasites and pathogenic bacteria in fertiliser; price risk; cyclical risk; risk of competition; currency, credit and interest rate risk.

Deoksiribonükleik asitin (DNA) 1953 yılında keşfedilmesi ve 2003 yılında “İnsan Genom Projesi” nin tamamlanması ile birlikte genetik alanındaki ilerlemeler çok ciddi bir ivme kazanmıştır. Genetik alanındaki araştırmalarda multidisipliner çalışma yaklaşımları da yer bulmaya başlamıştır. Bu yaklaşımlardan birisi de beslenme ve genetiktir. Epigenetik, DNA baz diziliminde herhangi bir değişiklik olmadan, gen ifade profilinin farklılaşarak sonraki kuşaklara aktarılmasıdır. Epigenetik mekanizmalar genlerin ifadesini arttırıp azaltabildiği gibi genlerin sessizleştirilmesinde de etkilidir. DNA metilasyonu, histon modifikasyonları ve kodlanmayan ribonükleik asitler (RNA) başlıca epigenetik mekanizmalardır. Epigenetik modifikasyonlar erken embriyonik dönemdeki gelişim açısından da önemlidir. Son yıllarda yapılan çalışmalar besinlerde bulunan biyoaktif bileşenlerin epigenetik mekanizmalar üzerinde etkili olduğunu göstermiş ve bu alandaki araştırmalar için ilgi çekici olmuştur. Bu derlemede, kromatin yapı, temel epigenetik mekanizmalar açıklanmış ve epigenetik modifikasyonları etkileyen besin biyoaktif bileşenleri ile ilgili yapılmış çalışmalara yer verilmiştir.

Abstract Determination of the best employees in a company aims to improve competitiveness and give awards to employees who have high dedication to the company. Difficulties in evaluating employees are the many assessment factors and characteristics of the appraisal and who will provide the appraisal, so that the appraisal is appropriate and transparent. Employee performance appraisal is carried out by 2 assessors namely the company manager and the head of the human resource management department (HRD) and consists of a number of criteria. The assessment will be difficult if done manually considering that each assessor has their own preferences in conducting the assessment. To overcome this we need a computer system that helps decision making, namely a group decision support system (GDSS) determining the best employees in a company

The group decision support system developed in this study uses the AHP and BORDA methods to assist group decision making. AHP method is used for decision making in each appraiser, while the Borda method is used to combine the decision results of each appraiser so that the final result is the best employee in the company. Based on the final results of the best employee determination system in the form of ranking the final value of each employee. The highest value is used as a recommendation as the best employee.
