description: (Abridged) The star-formation rate (SFR) quantitatively describes the star-formation process in galaxies. Current ways to calibrate this rate do not usually employ observational methods accounting for the low-mass end of stellar populations as their signatures are too weak. Accessing the bulk of protostellar activity within galactic star-forming regions can be achieved by tracing signposts of ongoing star formation. One such signpost is molecular outflows, which are bright in molecular emission. We propose to utilize the protostellar outflow emission as a tracer of the SFR. In this work, we introduce a novel version of the galaxy-in-a-box model, which can be used to relate molecular emission from star formation in galaxies with the SFR. We measured the predicted para-H2O emission at 988 GHz and corresponding SFRs for galaxies with LFIR = $10^8$ - $10^{11}$ L$_\odot$ in a distance-independent manner, and compared them with expectations from observations. We evaluated the derived results by varying the star formation efficiency, the free-fall time scaling factor, and the initial mass function. For the chosen H2O transition, relying on the current Galactic observations and star formation properties, we are underestimating the total galactic emission, while overestimating the SFRs, particularly for more starburst-like configurations. The current version of the galaxy-in-a-box model accounts for a limited number of processes and configurations, that is, it focuses on ongoing star formation in massive young clusters in a spiral galaxy. Therefore, the inferred results, which underestimate the emission and overestimate the SFR, are not surprising: known sources of emission are not included in the model. To improve the results, the next version of the model needs to include a more detailed treatment of the entire galactic ecosystem and other processes that would contribute to the emission.

description: Leucopis bursaria Rondani, 1848
ORIGINAL DESCRIPTION: 1848a: 437.
TYPE LOCALITY: Rondani gave no type locality in his original description but presumably it is Parma (Italy) because he referred to observations made by himself and E. Berté (from Parma).
TYPE MATERIAL: 1 ♂, lectotype (with puparium, dissected) (MZUF: Box 35): Leucopis Mgn / bursaria Rnd., [illegible words] … in galle ulmi / 1818 / Lectotypus Leucopis bursaria Rondani det. G. Morge, Ex. 15 [not designated] / Lectotypus ♂ Leucopis (Leucopis) bursaria Rondani, 1847 [sic!], A. Raspi det.
PARALECTOTYPE NOT EXAMINED: 1 ♂ (MZUF: Box 35): Leucopis Mgn / bursaria Rnd., [illegible words] … in galle ulmi / 1818 / Syntypus Chamaemyia bursaria (Rond.), det. G. Morge, Ex. 16.
CURRENT STATUS: valid species (Tanasijtshuk 1984: 226, Nartshuk et al. 1995: 7, Raspi 2003: 101).
REMARKS: Rondani (1848a: 437) described Leucopis bursaria from two specimens received from E. Berté who reared them from larvae mining the leaves of the black poplar Populus nigra Linnaeus, 1753. Raspi (2003: 105) designated a lectotype (♂) but did not mention an additional male in the MZUF numbered “1818” (this additional specimen is a paralectotype).

The relationship between acculturation and neuropsychological test performances.
Creators: name: Tan, Yi Wen

description: Many neuropsychological tests are described as biased toward Western cultural orientations, thus may not be accurately measuring cognitive abilities of ethnic minorities. Such tests are theorised to also measure the construct of acculturation. However, the operationalisation of acculturation, and neuropsychological tests are inconsistent across the literature. Therefore, the relationship between acculturation and test performances, and the practical value of acculturation during clinical examination is unclear. Four major investigations were conducted in this thesis to assess the relationship between acculturation and test performance. A systematic literature review revealed heterogeneity over different studies, but higher levels of adoption in acculturation broadly influenced better performance. The effects of acculturation could be unique to sample characteristics within each study, and the clinical use of acculturation was inconclusive. Limitations identified among these studies informed subsequent investigations in this thesis. An empirical study found that the language component of adoption predicted tests of language, and cultural knowledge predicted tests of orientation. However, a different measure of historical experiences with language predicted rates of false positives for a group of healthy ethnic minorities, better than ratings of acculturation. The introduction of ethnicity could have altered findings for rates of false positives on test performances. However, ethnicity and ratings of acculturation did not interact when predicting test performances, each predicted different types of tests independently. A further investigation revealed that dimensions of cultural intelligence could be underlying mechanisms involved in domains of acculturation. In conclusion, the domain of language and culturally specific knowledge were most likely influential toward test performance, but it was uncertain what type of neuropsychological tests would be more sensitive to these domains. The practical use of ratings of acculturative scales, when assessing for the probability of scoring a true negative, was reduced to language proficiency. Other factors (motivation, test length, fatigue) should not be overlooked when testing ethnic minorities. Limitations of the study, original contributions, and future directions were discussed.

description: The Landau-Ginzburg (LG) model for membranes is numerically studied on triangulated spheres in ${\bf R}^3$. The LG model is in sharp contrast to the model of Helfrich-Polyakov (HP). The reason for this difference is that the curvature energy of the LG (HP) Hamiltonian is defined by means of the tangential (normal) vector of the surface. For this reason the curvature energy of the LG model includes the in-plane bending or shear energy component, which is not included in the curvature energy of the HP model. From the simulation data, we find that the LG model undergoes a first-order collapse transition. The results of the LG model in the higher dimensional spaces ${\bf R}^d (d>3)$ and on the self-avoiding surfaces in ${\bf R}^3$ are presented and discussed. We also study the David-Guitter (DG) model, which is a variant of the LG model, and find that the DG model undergoes a first-order transition. It is also found that the transition can be observed only on the homogeneous surfaces, which are composed of almost uniform triangles according to the condition that the induced metric ${\partial_a {\bf r}}\cdot{\partial_b {\bf r}}$ is close to $δ_{ab}$.

description: We construct a noncommutative version of a general renormalizable SO(10) GUT with Higgses in the 210, $\overline{126}, 45, 10$ and 120 irreps of SO(10) and a Peccei-Quinn symmetry. Thus, we formulate the noncommutative counterpart of a non-supersymmetric SO(10) GUT which has recently been shown to be consistent with all the physics below $M_{GUT}$. The simplicity of our construction --the simplicity of the Yukawa terms, in particular-- stems from the fact that the Higgses of our GUT can be viewed as elements of the Clifford algebra $\mathbb{C}\rm{l}_{10}(\mathbb{C})$; elements on which the SO(10) gauge transformations act by conjugation. The noncommutative GUT we build contains tree-level interactions among different Higgs species that are absent in their ordinary counterpart as they are forbidden by SO(10) and Lorentz invariance. The existence of these interactions helps to clearly distinguish noncommutative Minkowski space-time from ordinary Minkowski space-time.

description: PSR J1528-3146 is a 60.8 ms pulsar orbiting a heavy white dwarf (WD) companion, with an orbital period of 3.18 d. This work aimed at characterizing the pulsar's astrometric, spin and orbital parameters by analyzing timing measurements conducted at the Parkes, MeerKAT and Nançay radio telescopes over almost two decades. The measurement of post-Keplerian perturbations to the pulsar's orbit can be used to constrain the masses of the two component stars of the binary, and in turn inform us on the history of the system. We analyzed timing data from the Parkes, MeerKAT and Nançay radio telescopes collected over $\sim$16 yrs, obtaining a precise rotation ephemeris for PSR J1528-3146. A Bayesian analysis of the timing data was carried out to constrain the masses of the two components and the orientation of the orbit. We further analyzed the polarization properties of the pulsar, in order to constrain the orientations of the magnetic axis and of the line-of-sight with respect to the spin axis. We measured a significant rate of advance of periastron for the first time, and put constraints on the Shapiro delay in the system and on the rate of change of the projected semi-major axis of the pulsar's orbit. The Bayesian analysis yielded measurements for the pulsar and companion masses of respectively $M_p = 1.61_{-0.13}^{+0.14}$ M$_\odot$ and $M_c = 1.33_{-0.07}^{+0.08}$ M$_\odot$ (68\% C.L.), confirming that the companion is indeed massive. This companion mass as well as other characteristics of PSR J1528$-$3146 make this pulsar very similar to PSR J2222-0137, a 32.8 ms pulsar orbiting a WD whose heavy mass ($\sim 1.32$ M$_\odot$) was unique among pulsar-WD systems until now. Our measurements therefore suggest common evolutionary scenarios for PSRs J1528-3146 and J2222-0137.

description: Cosmological hydrodynamical simulations are studied in order to analyse generic trends for the stellar, baryonic and halo mass assembly of low-mass galaxies (M_* < 3 x 10^10 M_sun) as a function of their present halo mass, in the context of the Lambda-CDM scenario and common subgrid physics schemes. We obtain that smaller galaxies exhibit higher specific star formation rates and higher gas fractions. Although these trends are in rough agreement with observations, the absolute values of these quantities tend to be lower than observed ones since z~2. The simulated galaxy stellar mass fraction increases with halo mass, consistently with semi-empirical inferences. However, the predicted correlation between them shows negligible variations up to high z, while these inferences seem to indicate some evolution. The hot gas mass in z=0 halos is higher than the central galaxy mass by a factor of ~1-1.5 and this factor increases up to ~5-7 at z~2 for the smallest galaxies. The stellar, baryonic and halo evolutionary tracks of simulated galaxies show that smaller galaxies tend to delay their baryonic and stellar mass assembly with respect to the halo one. The Supernova feedback treatment included in this model plays a key role on this behaviour albeit the trend is still weaker than the one inferred from observations. At z>2, the overall properties of simulated galaxies are not in large disagreement with those derived from observations.

From the entanglement assisted construction we can reach an alternative definition of partially entanglement breaking channels.

description: Mass fractions of Cu, Zn, Ga, Ag, Cd, In, Sn and Tl were determined via isotope dilution quadrupole ICP-MS in twenty-one geological reference materials (RMs) and the carbonaceous chondrites Orgueil (CI1), Murchison (CM2) and Allende (CV3). The RMs comprise basaltic/mafic (BCR-2, BE-N, BHVO-1, BHVO-2, BIR-1, BRP-1, JB-2, OKUM, W-2, WS-E), intermediate/felsic (AGV-2, G-2, JA-2, RGM-1), ultramafic (DTS-2b, MUH-1, PCC-1, UB-N) and sedimentary (MAG-1, OU-6) rocks. Pressure digestion was applied for nonbasaltic samples to ensure effective sample digestion. For basaltic RMs, hot plate digestion was found to be sufficient for a quantitative recovery of the target elements. To minimise interferences and increase ion beam intensities during isotope ratio analyses by ICP-MS, separation of the target elements was carried out from single sample aliquots using a novel anion exchange procedure. The intermediate precision (2s) estimated from two to four replicate analyses was usually < 4% and results are in agreement with literature data, where available. Especially for Ag and Tl, the intermediate precision was compromised, likely due to low ion beam intensities and, hence, higher background and blank contributions. For ultramafic RMs, nugget effects and incomplete digestion might compromise the intermediate precision. Results for the carbonaceous chondrites Orgueil (CI1), Murchison (CM2) and Allende (CV3) agree well with previously reported data.

description: The valley-orbit coupling in a few-electron Si quantum dot is expected to be a function of its occupation number N. We study the spectrum of multivalley Si quantum dots for 2 <= N <= 4, showing that, counterintuitively, electron-electron interaction effects on the valley-orbit coupling are negligible. For N=2 they are suppressed by valley interference, for N=3 they vanish due to spinor overlaps, and for N = 4 they cancel between different pairs of electrons. To corroborate our theoretical findings, we examine the experimental energy spectrum of a few-electron metal-oxide-semiconductor quantum dot. The measured spin-valley state filling sequence in a magnetic field reveals that the valley-orbit coupling is definitively unaffected by the occupation number.

description: The Higgs boson plays a central role in the Standard Model, as well as in theories which go beyond it. This article is therefore divided into two parts. The first takes s historical approach and shows how the mass problem entered weak interaction theory from the beginning and how it was solved by invoking the Higgs boson. This is followed by a construction of the Glashow-Salam-Weinberg model, again stressing the role played by the Higgs doublet. This part culminates in the Higgs boson discovery of 2012. The second part first discusses the shortcomings of the Standard Model and then touches upon the major theories which try to improve upon it, mostly with profound consequences on the Higgs sector. This is followed up by short descriptions of a number of popular extensions of the Higgs sector, and culminates in a brief introduction to effective field theory approaches to studying the Higgs sector.

description: Convection in planetary mantles is in the so-called mixed heating mode; it is driven by heating from below, due to a hotter core, as well as heating from within, due to radiogenic heating and secular cooling. Thus, in order to model the thermal evolution of terrestrial planets, we require the parameterization of heat flux for mixed heated convection in particular. However, deriving such a parameterization from basic principles is an elusive task. While scaling laws for purely internal heating and purely basal heating have been successfully determined using the idea that thermal boundary layers are marginally stable, recent theoretical analyses have questioned the applicability of this idea to convection in the mixed heating mode. Here, we present a scaling approach that is rooted in the physics of convection, including the boundary layer stability criterion. We show that, as long as interactions between thermal boundary layers are properly accounted for, this criterion succeeds in describing relationships between thermal boundary layer properties for mixed heated convection. The surface heat flux of a convecting fluid is locally determined by the properties of the upper thermal boundary layer, as opposed to globally determined. Our foundational scaling approach can be readily extended to nearly any complexity of convection within planetary mantles.

A bow-shock will form as a consequence of the interaction of the jet with the winds of stars and particles can be accelerated up to relativistic energies in these shocks. We compute the non-thermal radiation produced by relativistic electrons from radio to gamma-rays. This radiation may be significant, and its detection might yield information on the properties of the stellar population in the galaxy nucleus, as well as on the relativistic jet. This emission is expected to be relevant for nearby non-blazar sources.

description: Trending topics are the online conversations that grab collective attention on social media. They are continually changing and often reflect exogenous events that happen in the real world. Trends are localized in space and time as they are driven by activity in specific geographic areas that act as sources of traffic and information flow. Taken independently, trends and geography have been discussed in recent literature on online social media; although, so far, little has been done to characterize the relation between trends and geography. Here we investigate more than eleven thousand topics that trended on Twitter in 63 main US locations during a period of 50 days in 2013. This data allows us to study the origins and pathways of trends, how they compete for popularity at the local level to emerge as winners at the country level, and what dynamics underlie their production and consumption in different geographic areas. We identify two main classes of trending topics: those that surface locally, coinciding with three different geographic clusters (East coast, Midwest and Southwest); and those that emerge globally from several metropolitan areas, coinciding with the major air traffic hubs of the country. These hubs act as trendsetters, generating topics that eventually trend at the country level, and driving the conversation across the country. This poses an intriguing conjecture, drawing a parallel between the spread of information and diseases: Do trends travel faster by airplane than over the Internet?

The interactions of these strategies and their plasticity are, however, affected by soil nutrient status throughout plant growth. Such plasticity is decisive for plant phosphorus (P) acquisition in P‐limited soils. We investigated the P acquisition strategies and their plasticity of two maize genotypes characterized by the presence or absence of root hairs. We hypothesized that in the absence of root hairs plant growth is facilitated by traits with complementary functions, e.g., by higher root mycorrhizal colonization. This dependence on complementary traits will decrease in P fertilized soils. At early growth stages, root hairs are of little benefit for nutrient uptake. Regardless of the presence or absence of root hairs, plants produced average root biomass of 0.14 g per plant and exhibited 23% root mycorrhizal colonization. At later growth stages of maize, contrasting mechanisms with functional complementarity explained similar plant biomass production under P limitation: the presence of root hairs versus higher root mycorrhizal colonization (67%) favored by increased fine root diameter in absence of root hairs. P fertilization decreased the dependence of plant on specific root traits for nutrient acquisition. Through root trait plasticity, plants can minimize trade‐offs for developing and maintaining functional traits, while increasing the benefit in terms of nutrient acquisition and plant growth. The present study highlights the plasticity of functional root traits for efficient nutrient acquisition strategies in agricultural systems with low nutrient availability.

description: The nature of the interaction between low-excitation gas filaments at ~10^4 K, seen in optical line emission, and diffuse X-ray emitting coronal gas at ~10^7 K in the centers of galaxy clusters remains a puzzle. The presence of a strong, empirical correlation between the two gas phases is indicative of a fundamental relationship between them, though as yet of undetermined cause. The cooler filaments, originally thought to have condensed from the hot gas, could also arise from a merger or the disturbance of cool circumnuclear gas by nuclear activity. Here, we have searched for intrinsic line emission polarization in cool core galaxy clusters as a diagnostic of fundamental transport processes. Drawing on developments in solar astrophysics, direct energetic particle impact induced polarization holds the promise to definitively determine the role of collisional processes such as thermal conduction in the ISM physics of galaxy clusters, while providing insight into other highly anisotropic excitation mechanisms such as shocks, intense radiation fields and suprathermal particles. Under certain physical conditions, theoretical calculations predict of order ten percent polarization. Our observations of the filaments in four nearby cool core clusters place stringent upper limits (<0.1%) on the presence of emission line polarization, requiring that if thermal conduction is operative, the thermal gradients are not in the saturated regime. This limit is consistent with theoretical models of the thermal structure of filament interfaces.

The experience of entrepreneurial exit : an exploratory study of average micro and small business owners
Creators: name: Pauley, Matthew Kevin
Publisher: name: University of St Andrews
Year: 2019
Subjects: subject: HB615.P2

description: This thesis develops a typology and a test of how micro and small business owners experience the entrepreneurial exit process and the primary factors triggering such action. The current study explores the narratives of 40 entrepreneurs from diverse industries in the Southern Ontario region of Canada that discuss 51 retrospective accounts of exits. The departure process is a series of actions and/or events that trigger the relinquishment, by the entrepreneur’s own accord or not, of all ownership shares; operational duties and physical commitments to their venture. Entrepreneurship is significant for job creation; investment; economic growth and innovation. Society is set to experience the significant demographic shift of ‘baby boomers’ from the market, which is concerning for entrepreneurship as Canadian exit rates are increasing and a third have no succession plan. Much of the entrepreneurial exit literature explores the association between exit planning and outcomes on macro, organisational-levels. Because of its infancy as a field of study, exit literature tends to be piecemeal; crude and develops in isolation to other complimentary academic fields such as family business that can contribute knowledge on the succession process. The exit subfield lacks qualitative and processual contributions to understand the motivations of why entrepreneurs are exiting, which can tie existing academic contributions and develop a greater understanding on discontinuance. The current research contributes to the entrepreneurial exit; entrepreneurship and family business literatures by developing a typology and test of the exit experiences of Model A: financial harvest exits and Model B: nonfinancial harvests. Key findings identify that the entrepreneurial exit process takes over a year to complete and has five distinct phases: starting; operating; triggering; exiting and post-exiting. Within the exit journey, Model A entrepreneurs rely on their weak networks to achieve a financial harvest, whereas Model B entrepreneurs seek alternative employment for stability before realising their intention to exit. Financial harvests; dissolving and defaulting exit types are planned outcomes whereas bankruptcy is a catastrophic result. The strong networks of the entrepreneur provide emotional support throughout the process which is necessary given the gradual decline in the entrepreneurs’ well-being throughout the journey. Having greater adaptability in the exiting process is beneficial compared to planning an exit strategy early in the venture.

Dalmannia parvula

description: Dalmannia parvula Rondani, 1857
ORIGINAL DESCRIPTION: 1857: 251.
TYPE LOCALITY: Meigen (1824: 150) gave no type locality in the original description of Dalmannia marginata (Meigen, 1824), but presumably it is Europe because the work deals with European species.
TYPE MATERIAL: see Remarks.
CURRENT STATUS: junior synonym of Dalmannia marginata (Meigen, 1824) (Chvála & Smith 1988: 271, Rivosecchi & Scaramozzino 1995: 4, Stuke 2017: 140).
REMARKS: Rondani (1857: 251) considered the males of Dalmannia marginata (Meigen, 1824) and Dalmannia marginella (Zetterstedt, 1844) and the females of Dalmannia flavipes Robineau-Desvoidy, 1830 as belonging to the same species but, instead of applying the Principle of Priority, incorrectly proposed the substitute name Dalmannia parvula. It has always been considered as a synonym of Dalmannia marginata (Meigen, 1824) (Schiner 1861a: 390, Schiner 1864: 113, Becker 1905: 272, Kröber 1925: 42, Chvála & Smith 1988: 271, Rivosecchi & Scaramozzino 1995: 4, Stuke 2017: 140), never as a valid species. The type material for Dalmannia parvula will be the same as for the name it was proposed to replace, i. e., Dalmannia marginata. Meigen (1824: 151) reported the types of Dalmannia marginata in M. Baumhauer’s collection. The holotype of Dalmannia marginata is in the MNHN (Muséum national d’Histoire naturelle 2020). Stuke (2017: 140) incorrectly reported the holotype of Dalmannia parvula as in the MZUF. Under the name Dalmannia parvula in the MSNC there is one specimen (non-type).

description: We report on a bright, nondegenerate type-I parametric down-conversion source, which is well suited for passive decoy-state quantum key distribution. We show the photon-number-resolved analysis over a broad range of pump powers and we prove heralded higher-order $n$-photon states up to $n=4$. The inferred photon click statistics exhibit excellent agreements to the theoretical predictions. From our measurement results we conclude that our source meets the requirements to avert photon-number-splitting attacks.

ORIGINAL DESCRIPTION: 1856: 58.
TYPE LOCALITY: “ in agri parmensis collibus [Parmese hills (Italy)]”.
TYPE MATERIAL: 1 ♂, syntype (MZUF: Box 8): Haustellia Desv. Gonirhynchus Rnd. / dispar Rnd., ♂ / 414; 2 ♀♀, syntypes (MZUF: Box 8): Haustellia Desv. Gonirhynchus [sic!] Rnd. / dispar Rnd. occulta Wdn, ♀ / 414.
CURRENT STATUS: junior synonym of Myopa occulta Wiedemann in Meigen, 1824 (Chvála & Smith 1988: 264, Rivosecchi & Scaramozzino 1995: 3, Stuke 2017: 147).
REMARKS: Rondani’s (1856: 58) key for the genus Gonirhynchus Rondani, 1856 lists Gonirhyncus dispar as its type species, but he did not provide a detailed description, number or sex of the specimens. He later (Rondani 1857: 241) redescribed this nominal species in detail, providing specific characters for the male and female. Stuke (2017: 1147) reported one male and two females in the MZUF. We also found three syntypes in this study.

description: This Insight argues that the rise and spread of the notions of "European sovereignty" and "European Union sovereignty" must be taken seriously. Since 2017, they have become central categories in the main political discourses on the EU. The paper first addresses the question whether European (or EU) sovereignty is an adequate concept to give account of the nature, or the future, of European integration. It answers negatively. Then the Insight describes the claim for "European sovereignty" as a discursive form. As such, it performs different functions that must be analysed: the notion of European sovereignty permits to mobilise the EU actors who aim to 'rebuild' Europe and it serves to accommodate conflicting visions of what the EU is and should be. To focus on language permits to understand why "European sovereignty" gains momentum in the discourses and the literature on EU integration.
Towards Participation in Museum Architecture

description: This thesis sets out to explore how museums can use the planning processes of museum buildings as a vehicle for fulfilling their social role, even before their establishment as physical entities. Considering people as experiential co-designers who hold a valuable tacit knowledge of design and museum matters, museums can transform the planning processes into a participatory endeavour. The thesis examines two examples of innovation in practice, two museum buildings built from scratch or redeveloped through participatory processes: The Maria Manetti Shrem Museum of Art (USA) and The Derby Silk Mill Museum of Making (UK). The first key finding of the thesis is that participatory intentions are not solely results of a purely social agenda, but also of a wider institutional agenda that could potentially seek to legitimise certain inequalities through a participatory endeavour. The research also found that the role of leadership is key for both inspiring and sustaining participatory initiatives. Another key finding is that a project widely communicating its participatory character could in fact involve similar forms and degrees of participation with a project with a less systematic approach towards its participatory nature. Additionally, the research shed more light on the systematisation of participatory planning processes of museum buildings and their key challenges and found that the source of funding could impact the degree of experiential co-designers’ participation in the project and “alienate” the outcomes from the initial participatory intentions. Finally, this thesis found that participatory planning processes are not necessarily antithetical to conventional planning processes and can be realised within the tangible, bureaucratic reality that frames any building project. Articulating the first steps towards a participatory model for museum architecture, this thesis manifests that participatory planning processes of museum buildings are a viable option and encourages both museum and design professionals to take little steps towards change.

description: (abridged) Far-infrared (FIR) line emission provides key information about the gas cooling and heating due to shocks and UV radiation associated with the early stages of star formation. Gas cooling via FIR lines might, however, depend on metallicity. We aim to quantify the FIR line emission and determine the spatial distribution of the CO rotational temperature, ultraviolet (UV) radiation field, and H2 number density toward the embedded cluster Gy 3-7 in the CMa-l224 star-forming region, whose metallicity is expected to be intermediate between that of the LMC and the Solar neighborhood. By comparing the total luminosities of CO and [O I] toward Gy 3-7 with values found for low- and high-mass protostars extending over a broad range of metallicities, we also aim to identify the possible effects of metallicity on the FIR line cooling within our Galaxy. We studied SOFIA/FIFI-LS spectra of Gy 3-7 covering several FIR lines. The spatial extent of CO high-J (J>14) emission resembles that of the elongated 160 um continuum emission detected with Herschel. The CO transitions from J=14-13 to J=16-15 are detected throughout the cluster and show a median rotational temperature of 170+/-30 K on Boltzmann diagrams. Comparisons to other protostars observed with Herschel show a good agreement with intermediate-mass sources in the inner Galaxy. Assuming an origin of the [O I] and high-J CO emission in UV-irradiated C-shocks, we obtained pre-shock H2 number densities of 10^4-5 cm-3 and UV radiation field strengths of 0.1-10 Habing fields. Far-IR line observations reveal ongoing star formation in Gy 3-7, dominated by intermediate-mass Class 0/I young stellar objects. The ratio of molecular-to-atomic far-IR line emission shows a decreasing trend with bolometric luminosities of the protostars. However, it does not indicate that the low-metallicity has an impact on the line cooling in Gy 3-7.
