Three Conceptions of Sovereignty in Contemporary Investment Law
Authors: John Taylor St
Published: May 2023

Contemporary investment law is often depicted as a field in which transnational corporations and other private actors float freely above territorially bound, constrained states. Investment law epitomises fears about the erosion of sovereignty in these depictions. Yet sovereignty is a concept with layers of meaning, and a loss of policymaking autonomy, while important, is only one story of sovereignty in investment law. This chapter draws out three conceptions of sovereignty and how they manifest to officials negotiating investment law reform at the United Nations today. The first conception is sovereignty as control, as supreme authority within a defined territory. Concerns that investment law has eroded the ability of states to make policy fit here. The second conception is sovereignty as eligibility, as recognition that a government is eligible to participate in intergovernmental deliberations. Recognised states are the only actors eligible to participate formally in investment law reform at the United Nations. The third conception is sovereignty as capability, as being able to participate meaningfully in intergovernmental deliberations. While all governments are eligible, their actual participation in reform varies. In investment law, the persistence of sovereignty serves as a bridge to enduring questions about who should participate in rulemaking.
El Niño, Cholera, and the Productive Uncertainties of Water in Nairobi
Authors: Fontein Joost
Published: May 2023

2015 was an El Niño year. In Nairobi, before the first expected deluge of the ‘short’ rainy season (October to December), alerts were issued about the impending risk of floodings and cholera. Much of this anticipation was based on memories of the devastating 1997 El Niño, when floodings, landslides and cholera killed thousands of people across the country. Focusing on the nexus of weather, sanitation and disease in Mathare, one of Nairobi’s many ‘neglected slums’, this chapter explores how material and corporal flows – and the processes that manage and contain, or not, such flows – are deeply imbricated in the production, reproduction and contestation of different forms of sovereignty and legitimacy in the city. The scarcity of toilets, drinking water and sanitation in Nairobi’s ‘slums’, reflects their social, economic and political ‘marginality’ from the central state, and can generate deep (sometimes life-threatening) deprivations. But it also offers opportunities for different emergent structures and practices of authority and sovereignty to emerge, as ‘reformed’ gangs, community groups, NGOs and city authorities jostle to assert control over service provision. This chapter explores what the anticipation of the 2015 El Niño afforded for contested regimes of sovereignty and legitimacy to do with water in Mathare.
Exile, Music, and Cultural Translation: Gerhard’s Transnational Chronotopes
Authors: Llano Samuel
Published: May 2023

What was the meaning of exile’s impact on Gerhard's life and music? To what extent did he experience exile as trauma, or as a “stimulus for creation” (Bartra)? To overcome the limiting dualism trauma/creativity, this chapter considers the ways in which Gerhard navigated the complex map of continuities and ruptures that forced migration placed him on. Through what acts of cultural translation did he make meaning of exile? Through recourse to Bakhtin's theory of the chronotope, this chapter analyses the impact of exile on the “connectedness of temporal and spatial relationships” to which Gerhard strove through his music. I consider the extent to which exile threatened and undermined this connectedness and assess the ways in which Gerhard's music may be regarded as constitutive of a peculiar chronotope of exile. I also take advantage of literary theory's understanding(s) of the chronotope to probe the conflicting temporalities of Spanish modernity (Balibrea) and their manifestation in and through Gerhard's music. Gerhard's post-1939 music lends itself particularly well to this type of analysis because of the complex ways in which it re-creates Spain and Catalonia as multi-layered archives of memory.
The Mobility and Migration Revolution in 3rd Millennium BC Europe
Authors: Heyd Volker
Published: May 2023

Mobility and migrations are key for understanding cultural change. Recent advances in isotopic and aDNA studies make this apparent for the Early Neolithic, as well as the Copper Age/Early Bronze Age transition of the 4th/3rd millennium BC. However, there is no consensus on the scale, extent, directions, or speed of events. We likewise lack good models for the mechanisms behind the changing records. This paper focuses on four events in which archaeology and genetic studies show westward movements: Yamnaya, Early Corded Ware, Later Corded Ware, and ‘steppe’ Bell Beaker. Noted is the role of volatile boundaries of the forest-steppe region between the Dnieper and Dniester Rivers for the formation of Corded Ware, and the border triangle of France, Germany, and Switzerland for ‘steppe’ Bell Beaker groups. Models for further testing include the possible origins of gendered burial customs of Corded Ware and Bell Beaker cultures in the north-Pontic Zhivotilovka-Volchansk group, the role of Bohemia and the Elbe River in the earliest spread of Corded Ware, and changes of eastern origin affecting France.
Bronze Age Travellers
Authors: Kristiansen Kristian
Published: May 2023

This paper reconstructs the geographical and social horizons of some typical Bronze Age travellers and wanderers, the institutions that supported them, and distances covered. From this, we may deduce that they travelled along well-trodden paths in familiar landscapes and with familiar destinations of social peers along the route. The same was true of maritime journeys, where destinations were marked by coastal cairns along the route and safe natural harbours for resting. In their vicinity, we often find rock art panels whose motifs point to ceremonies when meeting your peers and celebrating guest-friendship. These peers all belonged to the chiefly elites of free farmers, whether warriors, traders, craft specialists, learned persons, whether male or female, children, teenagers, or grown-ups.
Marriage, Motherhood, and Mobility in Bronze and Iron Age Central Europe
Authors: Rebay-Salisbury Katharina
Published: May 2023

Female mobility, traced through interdisciplinary studies of human remains, is commonly explained by exogamy and patrilocal residence patterns. In order to understand how female movement might have shaped societies, we need to examine marriage and motherhood as social conventions and institutions. This paper explores the meaning of marriage in prehistoric societies, its relationship to motherhood, as well as mobility in the context of post-marital residence, drawing on evolutionary origins and cross-cultural observations. Polygyny, the marriage of a man with several women, and serial monogamy resulting from women dying in childbirth may impact how marriage networks may have operated. The age at which women had their first children, maternal mortality, as well as the total number of children per woman may constitute decisive variables for mobility. Exploring the intersections of marriage, motherhood, and gendered mobility significantly advances our knowledge of the social configurations in Bronze and Iron Age Central Europe.

Authors:   Asia Metropolitan University, Malaysia., Niu Xu Ren
Published: May 2023

As a positive psychological resource possessed by individuals, psychological capital can effectively resist the double impact of the new crown epidemic and entrepreneurial pressure on digital entrepreneurs. Therefore, it is of great significance to pay attention to the level of psychological capital of digital entrepreneurs. The purpose of this thesis reviews and summarizes the relevant literature on digital entrepreneurship and psychological capital and finds that the psychological capital of digital entrepreneurs refers to the ability of digital entrepreneurs to positively influence when they encounter certain special events (such as the emergence of new digital technologies or opportunities). In this model, digital entrepreneurship ability is used as an intermediary variable. Research design based on exploratory factor analysis, confirmatory factor analysis and Pears on correlation analysis were used to test the reliability and validity of the questionnaire, and hypothesis testing was carried out by constructing structural equation model and bootstrap method. The findings and results obtained show that most of the hypotheses proposed in this thesis are supported by data and verified by methods. The main research implications and conclusions are as follows: (1) The psychological capital of digital entrepreneurs significantly and positively affects entrepreneurial performance; (2) The psychological capital of digital entrepreneurs significantly and positively affects entrepreneurial performance ; Capital positively affects digital entrepreneurial ability ; (3) Digital entrepreneurial ability has a significant positive relationship with entrepreneurial performance ; ( 4 ) Digital entrepreneurial ability plays a partial mediating role between digital entrepreneurial psychological capital and entrepreneurial performance ; (5) environmental dynamism plays a significant positive moderating role between psychological capital and digital entrepreneurial ability, and between digital entrepreneurial ability and entrepreneurial performance.

Introduction. With the beginning of the pandemic caused by the COVID-19 virus, restrictions on movement, the so-called “lockdown” were applied by many governments. As a result of these actions taken against the transmission of the COVID-19 virus, the use of digital devices has increased, i.e. the time spent in front of screens has increased. Methods. This paper dealt with a bibliometric analysis of scientific publications on the topic of screen time in children and adolescents during the COVID-19 pandemic. The Dimensions database was chosen as the data source. No time frame is given, but given the topic, publications from 2020-2023 are included in the analysis. The data were analyzed in the VOSviewer program, specified for bibliometric and visual data analysis. Results. Map of word co-occurrence show that there are three different clusters. In the red cluster, consisting of 53 terms, the most frequent terms are sleep (124), lifestyle (103) and restriction (83), while in the green cluster, consisting of 41 terms, family (126), education (88), relationship (86) are the most represented. The blue cluster consists of significantly fewer terms, 12 of them, of which anxiety (91), symptom (81), depression (58) are the most represented. Conclusion. Based on the bibliometric analysis, we can conclude that the scientists were mostly concerned with the impact of the screen time phenomenon on the physical health of children and adolescents. In addition, screen time has been linked to mental health, education and socio-emotional relationships.

Authors:   M. R. Ambedkar dental college and hospital, India, Ramdev Poojya , Shruthi C. S. , Jangada Rimmi , Kothari Disha
Published: May 2023

Osseointegration is a critical factor for the clinical success of any oral implants. The unique characteristics of zirconia as a material for dental implants being high toughness and strength, aesthetic factor, excellent osseointegration behaviour and biocompatibility. Implants with rough surface favour bone anchoring, biomechanical stability, increased bone implant contact and removal torque or push in strength values compared to smooth surface implants. Greyish discoloration of peri-implant mucosa is a challenge especially in anterior titanium implant restoration. Zirconia abutments customized for single crown showed excellent survival for 5 years. Restoring single tooth and up to 3 adjacent missing teeth with zirconia implants are compatible to titanium implants. Evidence exists on improved osseointegration on surface modification of zirconia implants with enhanced cell response. Zirconia implants with modified surface displays features of osseointegration similar to titanium implants. Results are promising for dental application in future.

Studies have indicated deranged post-exercise physiological responses in hypohydrated subjects. The study investigated the effect of pre-exercise water ingestion on metabolic, autonomic and cardiovascular responses to prolonged exercise in mildly active male Nigerian students. 36 mildly active young males who emerged from random sampling were assigned into exercise groups I, II and III and were administered 0 L, 0.5 L and 1 L of drinking water at 15°C respectively. Responses were evaluated as % change between post- and pre-exercise levels and statistical analysis was conducted using SPSS-23. When compared with group I, baroreflex sensitivity (BRS), pulse rate (PR), systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse pressure (PP), mean arterial blood pressure (MAP), rate pressure product (RPP), double product (DoP), Calculated Cardiac Output (CCO) and Peripheral Oxygen Saturation (SP02) responses were significantly raised in groups II and III. Alanine transaminase (ALT), aspartate transaminase (AST) and alkaline phosphatase (ALP) responses were significantly lower in group III when compared with group I or group II. Peak PR, DoP and CCO responses occurred in group II while ALT, AST and ALP responses reached the nadir in group III. As far as groups II and III were concerned, hematocrit, hemoglobin and RBC responses did not significantly differ from group I but BRS positively and negatively correlated with DoP (r=0.952, P<0.05) and SPO2 (r=-0.568, P<0.05) respectively in both groups. In conclusion, the study showed that ingestion of 1 liters of water prior to prolonged exercise modulated neurovascular, cardiovascular and metabolic responses to prolonged exercise in mildly active male students.
Therapeutic Potential of NAD+ Precursors and Aging-related Diseases
Authors:   Cranbrook Kingswood Upper School, 550 Lone Pine Rd, Bloomfield Hills, MI 48304, USA, Gan Estella
Published: May 2023

Nicotinamide adenine dinucleotide (NAD+) plays fundamental roles in human life and health as an essential cofactor and substrate for a great number of vital biological processes. A growing body of evidence has demonstrated that the development of many age-related degenerative diseases, including dementia, heart failure, and diabetes, are linked with an age-dependent depletion in cellular NAD+ levels. Preclinical studies have shown that the restoration of NAD+ levels through NAD+ precursors, nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) supplementation, reduces the risk of heart failure, ameliorates the manifestations of Alzheimer's and Parkinson's, and improves insulin-sensitivity in type 2 diabetes. In recent years, multiple clinical studies have indicated that NR and NMN supplements are well tolerated and effectively stimulate NAD+ metabolism in healthy subjects. Further efficacy studies of NR and NMN supplements in patients with degenerative diseases are under clinical trial. This article reviews the recent preclinical and clinical progress of NR and NMN supplements as potential therapies to treat aging-related diseases with a focus on cardiovascular disease, neurodegenerative disorders, and diabetes studies.

Schizophrenia is a severe mental disorder that affects approximately 1% of the U.S population and it is characterized by a wide range of symptoms including hallucination, delusion, and lack of pleasure. It is believed both genetic and environmental influences contribute to schizophrenia onset. Among environmental influences, vitamin D has been extensively studied as a risk factor for schizophrenia. Both developmental and adult vitamin D deficiencies have been demonstrated to be associated with schizophrenia. Developmental vitamin D supplementation during an early year of life could dramatically reduce the rate of schizophrenia development. In addition, adult vitamin D supplementation in schizophrenia patients was shown to decrease the disease’s severity. In this article, we review recent advances in the connection, therapeutic potential, and pathogenetic mechanism of vitamin D in schizophrenia.
Effect of Requisite Nutrition for Athletes of Endurance Training: A Non-Empirical Review
Authors:   Department of Human Kinetics and Health Education, Faculty of Education, Ahmadu Bello University, Zaria, Nigeria, Nwokoleme Vincent
Published: May 2023

Weakness during endurance exercise is associated with a reduction in muscle glycogen beyond the physiological basal level, the response to compensate for this effect has been through the increase in carbohydrate uptake. Also, other dietary combinations have shown effectiveness in the required carbohydrate supply in improving the performance of athletes before and during endurance workouts. The search was made in Green Science Hub, PubMed, Free Full PDF, and World Wide Web for randomized trials published from 1995 to 2022 with a basic interest in performance in endurance exercise. All citations amounted to 22 which were examined based on the inclusion criteria of randomization or crossover allocation to diet and the basic result was endurance performance. Four full-text articles qualified for inclusion and were added to the current review. In the days to weeks before testing, one trial with an increased fat diet versus carbohydrate enhanced performance, others proved infinitesimal in effect. There was no advantage in changing protein for carbohydrates during this period, but hazelnut consumption improved performance. In the pre-event meal, fat improved performance in combination with carbohydrate intake. During endurance events, interchanging carbohydrates with protein had different results on performance and should be studied more. Conclusively, carbohydrate provides the highest energy before and during activities for all endurance performance compared to other ones needed in high amount, including water.

This study determined the effect of Mind mapping instructional techniques (MMIT) on learners’ interest in secondary school (SS) Technical Drawing (TD). The interest of learners exposed to instruction in TD using MMIT was compared with learners exposed to instruction in TD using the traditional approach as control. Three research questions and 3 null hypotheses guided the study. A quasi-experimental research design was employed. The Participants were 298 SSII TD students for the 2018/2019 Academic session in Gwagwalada Area Council of Federal Capital Territory, Abuja. The sample was 86 TD students drawn through a multistage sampling technique. TD Interest Inventory (TDII) developed by the researcher and validated by three experts was the instrument used for data collection. The instrument was trial tested and its internal consistency index was determined using the Chronbach alpha procedure. A reliability coefficient index of 0.69 was obtained for the TDII. Data collected were analysed using mean and ANCOVA. Findings revealed that MMIT was more suitable for improving learners’ interest in TD than the Conventional or traditional method. Gender was not an established fact or variable that contributed to learners’ interest in TD when exposed to MMIT. Lastly, the research outcomes show a significant interaction effect of gender and treatment on interest. The study suggested adequate training of teachers on the use of MMIT in TD for secondary schools.

Authors: ANOM SURYA
Published: May 2023

Kondisi Hutan Mangrove di Pulau Panjang Kabupaten Serang saat ini dalam kondisi yang memprihatinkan, banyak diantaranya telah mati dan dalam kondisi yang buruk, keadaan tersebut mengakibatkan Pulau Panjang sering terkena abrasi dan banjir rob yang masuk pada wilayah pemukiman masyarakat. Penyebab kondisi tersebut oleh aktifitas penebangan mangrove oleh masyarakat sekitar. Bahwa kurangnya rasa memiliki masyarakat terhadap hutan mangrove yang ada pada wilayahnya karena faktor kebutuhan terhadap kayu mangrove dan pola fikir tentang keuntungan dari mangrove tersebut. Penulis melihat bahwa permasalahan itu perlu adanya terobosan pada masyarakat agar memiliki rasa memiliki terhadap mangrove dan berkeinginan untuk terus melestarikan keberadaan mangrove di lingkungannya. Terobosan berupa  pemberian insentif bagi masyarakat yang melestarikan mangrove. Ketentuan pelestarian mangrove telah banyak diatur oleh hukum positif, termasuk dalam Peraturan Daerah di Kabupaten Serang, namun Kabupaten Serang belum menerapkan peraturan atau regulasi tentang pemberian insentif pelestarian mangrove sehingga masyarakat cenderung melihat secara umum mangrove tidak memberikan keuntungan pada mereka. Dalam penulisan ini dilakukan dengan metode yuridis normatif, yaitu mengkaji faktor-faktor peraturan yang mengatur objek penulisan yang kemudian pengumpulan data melihat keadaan faktual yang kemudian menyimpulkan permasalahan tersebut

Perkembangan praktek korupsi dari tahun ke tahun semakin meningkat, baik dari kuantitas atau jumlahkerugian keuangan negara maupun dari segi kualitas semakin sistematis, canggih serta lingkupnya sudahmeluas dalam seluruh aspek masyarakat. Metode penelitian yang digunakan adalah suatu penelitian hukumnormatif dengan didukung data wawancara. Berdasarkan hasil penelitian diketahui bahwa pentingnyapenyadapan dan perekaman untuk dapat menjadi alat bukti yang sah dalam perkara tindak pidana korupsidikarenakan penyadapan dan perekaman merupakan salah satu faktor yang dapat mengungkap kejahatan yangdilakukan secara tertutup dan rapi yang cukup sulit pembuktiannya. Bagi seluruh aparat penegak hukum (KPK,Polri dan Kejaksaan) dalam hal melakukan penyadapan harus disesuaikan dengan peraturan perundangundangan yang berlaku di Indonesia, sehingga tidak terjadi kesewenang- wenangan dalam melaksanakan tugasmaupun fungsi masing-masing penegak hukum.

The current pandemic of coronavirus disease 2019 (COVID-19) introduced the need for the development and optimization of new alcohol-water based disinfectant formulations. Moreover, the limited supply chain of traditional active ingredients such as ethanol (EtOH) has excessively increased the base formula cost, thus, novel platforms are needed to design new strategies for disinfectant development. In this work, we devise a novel quantification method of disinfectant turbidity and foam thickness based on photographic image analysis of disinfectant to optimize formula preparation, which improves critical physicochemical parameters related to colloidal stability. Next, the numerical data obtained from the pixel photograph's values were ordered by applying a 24 factorial design, considering each disinfectant ingredient, followed by an analysis of variance (ANOVA) and counter with contour and surface plots, respectively. Furthermore, our novel method was validated using a linear regression test, consequently outlining the method's error value. Our results suggest that the photographic image analysis supported by the statistical model correlated satisfactorily with the real physicochemical behavior of disinfectant, showing that the EtOH-H2O system plays a crucial role in turbidity and foam height control. In addition, we predicted by Minitab Optimizer Tool the physicochemical and aesthetic conditions of the disinfectant, having an error of 5%. Our current approach opens up a novel path to incorporate novel active ingredients for a rapid formulation and potentially scalable method to fabricate disinfectants.

Due to the development of the third-generation semiconductors representative of gallium nitride (GaN), the microwave power devices are developing towards higher power, higher efficiency and high integration. However, the electromagnetic field effects are more significant inside the device. As a result, circuit-level based simulation techniques can no longer satisfy the accuracy requirements of device design. Therefore it is necessary to urgently establish the field-circuit co-simulation techniques to couple the active GaN devices with passive electromagnetic structures. In this work, we propose a high-precision discontinuous Galerkin time-domain method to analyze the performances of GAN-based high-power microwave devices. The extracted large-signal compact model of the GaN HEMT is incorporated into the electromagnetic field equations. A local time-stepping technique is adopted to remove the constraints of nonlinear compact models and multiscale elements on the stability conditions of the global algorithm. The comparisons among numerical simulations, experimental results, and software calculations demonstrate the excellent accuracy and efficiency of the proposed method, which can provide a theoretical analysis and design tool for the high reliability design of advanced high-power microwave devices.

In this paper, we conduct the experiment and simulation on 31D5/2+6S1/2(F = 4) Cs2 ultralong-range Rydberg molecules (ULRMs). These molecules are prepared by employing a two-photon photoassociation scheme. Two distinct ultralong-range Rydberg molecular signals are observed at the detuning –162.8 MHz and –66.6 MHz of 31D5/2 atomic resonant line, which are bound by the pure triplet potential and mixed singlet-triplet potential, respectively. We use the model of scattering interaction between the Rydberg electron and ground-state atom to perform the simulation. The molecular potential-energy curves are obtained by solving the Hamiltonian on a grid of intermolecular distances R. The calculations of the binding energy of pure triplet and mixed singlet-triplet v = 0 vibrational states are compared with the experimental measurements. The calculated and measured values of the binding energy are in good agreement. The s-wave pure triplet and singlet zero-energy scattering length are obtained to be \begin{document}${a}_{{\rm{s}}}^{{\rm{T}}}({0})=-{19.16}{a}_{0}$\end{document} and \begin{document}$ {a}_{{\rm{s}}}^{{\rm{S}}}(0)=-{1.92}{a}_{0} $\end{document}, respectively. This kind of molecule with large size, abundant vibrational states and large permanent electric dipole moment is an excellent candidate for studying low-energy collision dynamics. The study of these molecules will further deepen and enrich the understanding of the special binding mechanism and exotic properties of the ULRMs.

The power of femtosecond lasers based on Ti: sapphire or Yb-doped gain media has reached a high level by using chirped pulse amplification. The dispersive elements are normally employed in CPA devices, thereby increasing the complexity and cost of the laser system. However, for the Nd-doped laser, its power can be amplified to hundreds of microjoules or even several millijoules directly without CPA technology. So compressing the picosecond pulse to obtain femtosecond laser pulses with hundreds of microjoules pulse energy by post-compression technology becomes meaningful. The pulsed post-compression technology is the combination of nonlinear spectral broadening and dispersion compensation. Currently, the most effective method of nonlinear spectral broadening is achieved through self-phase modulation. The multi-pass cell (MPC) device based on self-phase modulation for broadening spectral bandwidth has been extensively studied, since it was demonstrated. The MPC concept demonstrates significant practical benefits. Essentially, it requires only two curved mirrors and a Kerr medium in between, making it a cost-effective and easily implementable method. Moreover, the MPCs are robust, quite insensitive to beam pointing, and can evendeal with small mode mismatch without transmission losses. These favorable characteristics make MPCs very attractive not only for scientific applications, but also for commercial and facility laser systems where reliability is crucial. The striking progress of the technique in the past six years has made it possible to obtain high average power femtosecond laser.

In this work, we demonstrate the generation of a high average power femtosecond laser pulse by nonlinearly compressing the picosecond pulse in the Herriott multi-pass cell device, and the distribution of eigenmode is analyzed. With this efficient and robust scheme, the spectrum is broadened from 0.20 nm to 2.75 nm, with a broadening ratio of 13.75, and the pulse duration of a picosecond amplifier is compressed from 1.25 ps to 780 fs, with a compression factor of 16. The average power before and after pulse compression are 100 W and 71.3 W respectively, so the overall transmission reaches 71.3%. The present scheme offers a viable route to low-cost and simple-configuration high-power femtosecond lasers driven by Nd-doped picosecond amplifiers.
